To report safety of ocrelizumab (OCR) up to 7 years in patients with relapsing multiple sclerosis (RMS) and primary progressive multiple sclerosis (PPMS) enrolled in clinical trials or treated in real-world postmarketing settings. Safety analyses are based on integrated clinical and laboratory data for all patients who received OCR in 11 clinical trials, including the controlled treatment and open-label extension (OLE) periods of the phase 2 and 3 trials, plus the phase 3b trials VELOCE, CHORDS, CASTING, OBOE, ENSEMBLE, CONSONANCE, and LIBERTO. For selected adverse events (AEs), additional postmarketing data were used. Incidence rates of serious infections (SIs) and malignancies were contextualized using multiple epidemiologic sources. At data cutoff (January 2020), 5,680 patients with multiple sclerosis (MS) received OCR (18,218 patient-years [PY] of exposure) in clinical trials. Rates per 100 PY (95% confidence interval) of AEs (248; 246-251), serious AEs (7.3; 7.0-7.7), infusion-related reactions (25.9; 25.1-26.6), and infections (76.2; 74.9-77.4) were similar to those within the controlled treatment period of the phase 3 trials. Rates of the most common serious AEs, including SIs (2.01; 1.81-2.23) and malignancies (0.46; 0.37-0.57), were consistent with the ranges reported in epidemiologic data. Continuous administration of OCR for up to 7 years in clinical trials, as well as its broader use for more than 3 years in the real-world setting, are associated with a favorable and manageable safety profile, without emerging safety concerns, in a heterogeneous MS population. This analysis provides Class III evidence that long-term, continuous treatment with OCR has a consistent and favorable safety profile in patients with RMS and PPMS. This study is rated Class III because of the use of OLE data and historical controls. The phase IIIb A Study to Evaluate the Effects of Ocrelizumab on Immune Responses in Participants With Relapsing Forms of Multiple Sclerosis (VELOCE) study (NCT02545868) assessed responses to selected vaccines in ocrelizumab (OCR)-treated patients with relapsing multiple sclerosis. Patients were randomized 2:1 into the OCR group (n = 68; OCR 600 mg) or control group (n = 34; interferon beta or no disease-modifying therapy). All received tetanus toxoid (TT)-containing vaccine, Pneumovax (23-valent pneumococcal polysaccharide vaccine [23-PPV]), and keyhole limpet hemocyanin (KLH). The OCR group was subdivided into OCR1 (n = 33) and OCR2 (n = 35) at randomization. The OCR1 group received Prevnar (13-valent conjugate pneumococcal vaccine) 4 weeks after 23-PPV; the OCR2 and control groups received influenza vaccine. Vaccinations started 12 weeks after OCR initiation (OCR group) or on day 1 (control group). Positive response rate to TT vaccine at 8 weeks was 23.9% in the OCR vs 54.5% in the control group. Positive response rate to ≥5 serotypes in 23-PPV at 4 weeks was 71.6% in the OCR and 100% in the control group. Prevnar did not enhance response to pneumococcal serotypes in common with Pneumovax. Humoral response to KLH was decreased in the OCR vs control group. Seroprotection rates at 4 weeks against 5 influenza strains ranged from 55.6% to 80.0% in the OCR2 group and 75.0% to 97.0% in the control group. Peripherally B-cell-depleted OCR recipients mounted attenuated humoral responses to clinically relevant vaccines and the neoantigen KLH, suggesting that use of standard nonlive vaccines while on OCR treatment remains a consideration. For seasonal influenza vaccines, it is recommended to vaccinate patients on OCR because a potentially protective humoral response, even if attenuated, can be expected. This study provides Class II evidence confirming that the humoral response to nonlive vaccines in patients with relapsing multiple sclerosis after OCR treatment is attenuated compared with untreated or interferon beta-treated patients, but they can still be expected to be protective.

Recently launched esthetic botulinum toxin serotype A (BoNT/A) products include Nabota/Jeuveau, Meditoxin/Neuronox, and Botulax, which contain nontoxic accessory proteins and excipients. Clinical evidence supporting these formulations, including their purity and potential immunogenicity or their link to treatment failures, is limited. Any nonhuman protein, including nontoxin accessory proteins, can initiate immune reactions, especially if administered repeatedly, yet the issue of BoNT/A-induced immunogenicity is widely contested. However, there have been multiple reports of treatment failures and observations of BoNT/A-induced neutralizing antibodies. Compared with the purified formulation in Xeomin, these recently launched toxins contain higher total neurotoxin quantities, much of which is inactive and exposes patients to potentially immunogenic nontoxin proteins or inactive neurotoxins that increase their risk of developing treatment failure. Well-established products [especially abobotulinumtoxinA (Dysport), onabotulinumtoxinA (Botox) and Xeomin] are accompanied by comprehensive and long-ranging clinical evidence on safety and efficacy in esthetic facial indications, which still remains undisclosed for many of the recently introduced toxins. Clinicians need this information as patients will require repeated BoNT treatments and may be unnecessarily but cumulatively exposed to potential immunogens. To underscore the need for caution and further evidence, we review some of the issues surrounding BoNT/A-induced immunogenicity and antibody-induced treatment failures and argue that using highly purified toxins that do not negatively impact patient outcomes is a prudent clinical decision. All protein-based therapeutics, such as botulinum neurotoxin type A (BoNT/A), are potentially immunogenic and can lead to anaphylaxis, autoimmunity, or diminished or complete absence of therapeutic efficacy, especially if administered repeatedly. Therefore, the protein quantity in BoNT/A products is an important consideration when selecting products for treatment. However, essential formulation data are not always publicly accessible. The neurotoxin protein content of products newly introduced in Asia, such as (listed alphabetically) Botulax®, Meditoxin®, Nabota®, and Relatox®, was measured by sandwich enzyme-linked immunosorbent assay with antisera directed against BoNT/A compared to Xeomin®. Compared to Xeomin with no inactive neurotoxin, although Botulax and Nabota contained 844 and 754 pg of neurotoxin protein, respectively, the percentage of inactive neurotoxin was calculated to be 103 and 81, respectively, while the potency per pg of neurotoxin was 0.118 and 0.133 U, respectively. Meditoxin and Relatox had 575 and 578 pg of neurotoxins, respectively, marginally higher than that of Xeomin, while the percentage of inactive neurotoxins was 38 and 33, respectively, and the potency per pg of neurotoxin was 0.174 and 0.173 U, respectively. However, Xeomin, which has 416 pg/vial of purified neurotoxin and 0.240 U of efficacy per pg of neurotoxin, has the lowest neurotoxin protein content and consequently the highest specific potency compared to the four Asian BoNT/A preparations in this study. Although Botulax and Nabota had more neurotoxin than Xeomin in an equivalent volume, they contained greater amounts of inactive neurotoxin. In addition, although Meditoxin and Relatox had slightly more neurotoxin than Xeomin, both contained greater amounts of inactive neurotoxin. To review the medical literature on the outcomes and complications of various Food and Drug Administration-approved botulinum toxins for benign essential blepharospasm (BEB) and hemifacial spasm (HFS). Literature searches were last conducted in February 2017 in PubMed for articles published in English and in the Cochrane Library database without language limitations; studies published before 2000 were excluded. The combined searches yielded 127 citations. Of these, 13 articles were deemed appropriate for inclusion in this assessment, and the panel methodologist assigned ratings to them according to the level of evidence. A combined total of 1523 patients (1143 with BEB and 380 with HFS) were included in the 13 studies. Five studies provided level I evidence, 2 studies provided level II evidence, and 6 studies provided level III evidence. Pretarsal injections were more efficacious than preseptal injections (96% vs. 86%, respectively). Pretarsal injections also resulted in a higher response rate on clinical scales (P < 0.05) and a longer duration of maximum response for both HFS and BEB. Patients with HFS require lower overall doses of onabotulinumtoxinA than patients with BEB for a similar duration of effect. Adverse events were dose related, and they occurred more frequently in patients who were given more units. Level I evidence supports the efficacy of Botox (Allergan Corp., Irvine, CA), Meditoxin, and Xeomin (Merz Pharmaceuticals, Frankfurt am Main, Germany) for the treatment of BEB. Meditoxin and Botox have equivalent effectiveness and incidence of adverse events for BEB and HFS. Dysport (Ipsen Biopharmaceuticals, Inc, Paris, France) seems to have efficacy similar to Botox and Meditoxin for BEB and HFS, but any definitive conclusions from the 2 level II studies in this review are limited by differences in the methodologies used. Higher doses of Botox and Dysport result in more adverse events. Repeated treatments using Botox seem to maintain efficacy for treatment of facial dystonias over a follow-up period of at least 10 years, based on level III evidence. In the present study, we investigated the treatment efficacy and clinical outcomes of botulinum neurotoxin-A (BoNT-A) administered for longer than 5 years to patients with essential blepharospasm. We retrospectively reviewed 19 patients (male : female = 8 : 11) diagnosed with essential blepharospasm between March 2006 and July 2016 who underwent BoNT-A injections for over 5 years and were followed. Efficacy of 297 injections of Botox (n = 162), Meditoxin (n = 75), Hugel-tox (n = 40), or Dysport (n = 20) was based on the symptom improvement score at the final injection (-1, worse; 0, same; 1, better). Injection dose (botox unit), duration of efficacy (months), and adverse events were also investigated. Based on product type, significant differences in patient age (59.3 ± 9.8 years), disease period (5.0 ± 5.4 years), number of botulinum neurotoxin injections before visiting our clinic (1.6 ± 2.6), and follow-up period (7.2 ± 1.6 years) were not observed. Treatment efficacy score and injection dose of repetitive injections were 0.1 ± 0.5 and 39.1 ± 4.0 units, respectively, and did not show significant differences with repeated injections. Duration of response was 5.9 ± 5.4 months, but this significantly decreased as the injections were repeated (p < 0.01). Among the 297 injections, adverse events occurred 12 times (4.0%) with no severe sequelae. In this study, we showed that repetitive, long-term BoNT-A injections are considered a stable and effective treatment for essential blepharospasm in terms of consistent injection dose and maintenance of treatment efficacy. However, the duration of long-term efficacy could be decreased in patients injected repetitively. This study examined changes in masticatory function after botulinum toxin type A (BTX-A) injection using objective and subjective tests during 12 weeks. Also, we compared differences in masticatory function between group in which only masseter muscle (M group) was injected and group in which masseter and temporal muscle (M-T group) were injected. Forty subjects were assigned into two groups; M group (n = 20) and the M-T group (n = 20). The Meditoxin(®) was used as BTX-A injection. The mixing ability index (MAI) was used as the objective indicator, and visual analogue scale (VAS) and food intake abilit

Riehl's melanosis is a hyperpigmentation disorder that has a significant psychological and social impact on individuals. In the past 10 years, new categories have been developed, raising questions about how to classify Riehl's melanosis. The mechanism of this disease remains unclear, although the type IV hypersensitivity response caused by allergic sensitization, as well as genetic, ultraviolet radiation, and autoimmune factors, is to blame. Clinical manifestation, dermoscopy, reflectance confocal microscopy, patch/photopatch testing, histopathology, and a novel multimodality skin imaging system have been used for the diagnosis. A variety of therapies including topical skin-lightening agents, oral tranexamic acid, glycyrrhizin compound, chemical peels, and lasers and light therapies (intense pulsed light, 1064-nm Q-Switched Nd: YAG laser, 755-nm PicoWay laser, nonablative 1927-nm fractional thulium fiber laser, new pulsed-type microneedling radiofrequency), with improved effectiveness. The latest findings on possible biomarkers and their relationship to other autoimmune diseases were also summarized. Until recently, quality-switched nanosecond lasers have been the workhorse lasers in treating pigmented lesions. However, the recently commercialized picosecond lasers have provided physicians with a novel method to manage pigmented lesions. Most recently, the first picosecond laser with a 730-nm wavelength was developed to specifically target melanin and melanocytes. We report on two Asian patients with freckles, lentigines, and melasma who were successfully treated with a novel 730-nm Ti:Sapphire picosecond laser (Picoway®; Syneron Candela, Corp). The clinical outcome was measured by the global percent of clearance, which was evaluated by blinded observers by comparing the post-treatment photographs with the baseline photographs. In both patients, a significant pigmentary reduction was achieved with only one treatment session. In both patients, the treatments were well tolerated with minimal discomfort even without topical anesthesia. No post-inflammatory hyperpigmentation or repigmentation was observed until the 6-week follow-up. The pigmentary conditions treated included freckles, lentigines, and melasma. Both subjects showed clinical improvement, with the best results observed for the treatment of freckles such that 95% of the lesions achieved excellent response (75-94% lightening). The results of this case report indicate that a novel 730-nm Ti:Sapphire picosecond laser may be effective and safe in treating pigmentary disorders in darker-skinned patients. Therefore, further well-designed, prospective clinical trials are warranted to establish the potential of 730-nm picosecond lasers and determine the optimal treatment parameters in comparison to existing laser and light modalities.

Data on the treatment of the hyperpigmented component of scars are sparse. The authors aimed at evaluating the efficacy of the fractional 1,064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) picosecond laser in the treatment of the hyperpigmented component of scars. Sixteen patients with hyperpigmented scars underwent 3 to 8 treatment sessions at 3- to 6-week intervals with the 1,064-nm Nd:YAG picosecond laser (PicoWay, Candela, Resolve handpiece). The treatment response was evaluated by 2 noninvolved dermatologists on a global assessment scale (GAS) of 1 to 4. A Mexameter quantitatively evaluated the melanin content of the scar before and after laser treatments. The average GAS score of the 2 noninvolved dermatologists was 3.31 ± 0.57. The patients assessed their level of tolerance as good or excellent and their satisfaction level as moderate or high. The Mexameter showed that the melanin index decreased considerably (by 39.11 ± 11.58%) in all patients after treatment. The fractionated nonablative picosecond Nd:YAG laser was effective for the treatment of the hyperpigmented component of scars.

Various rejuvenation surgeries, including hyaluronic acid (HA) fillers, aim to address mid-face volume loss. However, literature on the comparative efficacy and safety of different HA fillers for the zygomatic area remains limited. This systematic review and network meta-analysis (NMA), adhering to NMA PRISMA 2020 and Cochrane guidelines. Searches were conducted on different bases. Eligible studies included patients with mid-face volume loss undergoing HA interventions. The primary outcome was the Global Aesthetic Improvement Scale (GAIS) at different time points and the incidence of adverse events. Among 1742 articles, six randomized controlled trials (RCTs) met the inclusion criteria with a total of 579 patients. The studies evaluated Giselleligne, VYC-20, Neuramis Lidocaine and ART-Filler. Results showed that Giselleligne demonstrated superior safety compared to VYC-20, ART-Filler and Neuramis-Lidocaine (Risk Ratios (RR) = 0.27, 95% Confidence interval (CI) [0.14; 0.54]), (RR = 0.36, 95% CI [0.17; 0.75], & RR = 0.22, 95% CI [0.07; 0.67]) respectively However, there were no significant differences in the Global Aesthetic Improvement Scale Assessment (GAIS) scores between HA fillers at 1, 3, and 6 months. While no significant differences were observed in efficacy among HA fillers, Giselleligne emerged as a potentially safer option for the cheeks volume restoration. The study emphasizes the need for further well-designed RCTs to explore the long-term safety and durability of HA fillers. These findings contribute valuable insights for clinicians and patients in making evidence-based decisions regarding mid-face rejuvenation options. Hyaluronic acid (HA)-based dermal fillers have been approved for various clinical indications, both cosmetic and medical. Previous studies that have assessed the performance of HA dermal fillers have primarily focused on evaluating filler durability, and only a few have studied their distribution within the tissues. The present study aimed to compare tissue integration of various types of HA dermal fillers having different clinical indications and varying injection depths. To examine the local inflammatory response and distribution pattern of 14 HA dermal fillers (six Neuramis [NEU], one Belotero [BEL], three Juvéderm [JUV], and four Restylane [RES]), each product was injected intradermally and subcutaneously at the backs of two male miniature pigs. Histopathological evaluation and visual examination of the tissue sections were conducted 1 and 4 weeks after injection. Mean inflammatory cell infiltration scores tended to be lower in response to fillers from the NEU and BEL series than to those from the JUV and RES series after intradermal and subcutaneous injection. Furthermore, the inflammatory response to fillers with higher physicochemical properties specifically designed for injection into deeper layers of the skin tended to be slightly higher than those designated for injection into more superficial layers. There was no significant difference in tissue integration according to clinical indication and injection depth, although fillers from the NEU and BEL series exhibited better tissue integration than those from the JUV and RES series. Our findings not only suggest that the local inflammatory response and tissue integration differ across HA dermal filler products, but also that these parameters could vary according to the recommended clinical indication and injection depth of the products. The long-term effectiveness and safety of hyaluronic acid fillers in mid-face volume restoration in Asians remain unclear. The objective of this study was to compare the long-term effectiveness and safety of Neuramis Volume Lidocaine (SHAPE-NVL) and Juvederm Voluma with Lidocaine (VYC-20L) in mid-face volume restoration in Asians. Overall, 88 Korean subjects with moderate-to-severe age-related mid-face volume deficit on the Mid-Face Volume Deficit Scale (MFVDS) received SHAPE-NVL on one side and VYC-20L on the contralateral side of the face. Of the 81 subjects who completed the 48-week primary study, 69 subjects were enrolled in an extension study lasting 104  weeks. MFVDS score and global aesthetic improvement were assessed at each visit. Response was defined as a ≥1-point reduction in MFVDS. At weeks 36 and 48, the responder rates for SHAPE-NVL were 81.93% and 80.72%, while those for VYC-20L were 85.54% and 81.92%, respectively. At the 104-week visit, the responder rates were 73.91% and 72.46% for SHAPE-NVL and VYC-20L, respectively. No subjects experienced any serious adverse events during the trial. SHAPE-NVL and VYC-20L showed comparable longevity and safety in mid-face volume restoration over 2  years in Asians. Both had durable effects for up to 2  years with minimal safety concerns. There have been few studies using hyaluronic acid fillers to restore mid-face volume deficit especially in Asians. This study compared the efficacy and safety of two highly cohesive hyaluronic acid fillers, Neuramis® Volume Lidocaine and Juvederm® Voluma® with Lidocaine (VYC-20L), for temporary restoration of mid-face volume in Asians. A total of 88 subjects with moderate to severe age-related mid-face volume deficit on the Mid-Face Volume Deficit Scale (MFVDS) received Neuramis® Volume Lidocaine on one side and VYC-20L on the other side of the face. Response was defined as a ≥1 point reduction in MFVDS at 24 weeks after the injection by photographic assessment. Secondary end points included photographic and live assessments of MFVDS and its changes at week 4, 12, and 24; global aesthetic improvements, as assessed by the investigators and the subjects at each visit; and the proportion of subjects who received touch-up treatment. The response rates of the sides treated with Neuramis® Volume Lidocaine and VYC-20L were identical (96.39%) at week 24, demonstrating that Neuramis® Volume Lidocaine was noninferior to VYC-20L. Photographic and live assessments of MFVDS and its changes, global aesthetic improvement, and the proportion of subjects who received touch-up treatment did not differ significantly during follow-up. Neuramis® Volume Lidocaine was not inferior to VYC-20L in temporarily restoring mid-face volume at 24 weeks after treatment. Both of these highly cohesive hyaluronic acid fillers can be used effectively and safely for the correction of mid-face volume loss in Asians. Hyaluronic acid dermal fillers are most frequently used for unwanted wrinkles. Recently, lidocaine has been incorporated into hyaluronic acid fillers to reduce injection discomfort. A randomized, multicenter, double-blind, intraindividual trial was designed to compare a new lidocaine-containing monophasic hyaluronic acid filler (Neuramis Deep Lidocaine) with a lidocaine-containing biphasic hyaluronic acid filler (Restylane Perlane-L) in moderate to severe nasolabial folds. Fifty-eight patients with moderate to severe nasolabial folds were randomized to an injection of Neuramis or Perlane-L in the left or right side of the face. Clinical efficacy and safety were assessed by blinded investigators, independent expert panels, and patients based on the Wrinkle Severity Rating Scale and the Global Aesthetic Improvement Scale at weeks 8, 16, and 24 after the injection. Wrinkle Severity Rating Scale improvement from baseline with Neuramis (1.64 ± 0.74) was significantly greater than with Perlane-L (1.45 ± 0.54) at week 24 (p < 0.05). The mean Global Aesthetic Improvement Scale score at week 24 was 2.36 ± 0.55 for Neuramis and 2.00 ± 0.50 for Perlane-L (p < 0.05). However, the difference in pain reduction between Neuramis- and Perlane-L-treated sides was not statistically significant. The efficacy and safety of Neuramis are comparable to those of Perlane-L in Wrinkle Severity Rating Scale and Global Aesthetic Improvement

Henneguya sp. is a crucial myxosporean parasite known to cause milky flesh or tapioca disease in the freshwater fish population, leading to heavy mortality. Studies to investigate its host range and to monitor their prevalence in wild and aquacultured fish are necessary. The infected orange-spotted snakehead (Channa aurantimaculata) fish samples showing clinical signs such as severe ulceration and open wounds on the mouth and operculum were collected from an ornamental fish-rearing unit in Chennai, Tamil Nadu. The sample was diagnosed with myxosporean infection by microscopic observation, morphological records and DNA sequencing followed by phylogenetic analysis. The Henneguya infection was identified in C. aurantimaculata for the first time. Necropsy of the infected fish revealed characteristic multifocal whitish-yellow, oval-shaped cysts measuring 3-5 mm in length on the liver and spleen. The wet mount of cysts showed numerous mature Henneguya spores that were uninucleate, elongated, lenticular and ellipsoidal with the bluntly rounded anterior end gradually tapering off to the posterior with a caudal elongation. The spore body measured 12.1 ± 0.9 μm (10.1-14.7 μm) × 7.1 ± 0.6 μm (5.3-8.5 μm) with two slightly unequal pyriform polar capsules of 6.1 ± 0.5 μm (5.1-7.4 )× 2.5 ± 0.4 μm (1.6-3.9) (large); 6.0 ± 0.4 μm (5.2-6.4) × 2.5 ± 0.3 μm (1.7-3.1) (small) and a caudal elongation of 16.1 ± 1.2 μm in length. The parasite was confirmed to be a Henneguya sp. by PCR amplification of SSrRNA followed by gene sequencing. The sequence generated was submitted in the GenBank under accession number PP852214.1 The maximum likelihood analysis revealed that the obtained sequence is a close relative of H. exilis with pairwise sequence variation of 3.3% and a homology of 99.04%. The findings highlight the potential impact of Henneguya sp. on ornamental fish health, underscoring the need for vigilant monitoring and management in India. Proliferative gill disease (PGD), caused by the myxozoan Henneguya ictaluri, has been the most notorious parasitic gill disease in the US catfish aquaculture industry. In 2019, an unusual gill disease caused by massive burdens of another myxozoan, Henneguya exilis, was described in channel (Ictalurus punctatus) × blue (Ictalurus furcatus) hybrid catfish. Targeted metagenomic sequencing and in situ hybridization (ISH) were used to differentiate these conditions by comparing myxozoan communities involved in lesion development and disease pathogenesis between massive H. exilis infections and PGD cases. Thirty ethanol-fixed gill holobranchs from 7 cases of massive H. exilis infection in hybrid catfish were subjected to targeted amplicon sequencing of the 18S rRNA gene and compared to a targeted metagenomic data set previously generated from clinical PGD case submissions. Furthermore, serial sections of 14 formalin-fixed gill holobranchs (2 per case) were analyzed by RNAscope duplex chromogenic ISH assays targeting 8 different myxozoan species. Targeted metagenomic and ISH data were concordant, indicating myxozoan community compositions significantly differ between PGD and massive branchial henneguyosis. Although PGD cases often consist of mixed species infections, massive branchial henneguyosis consisted of nearly pure H. exilis infections. Still, H. ictaluri was identified by ISH in association with infrequent PGD lesions, suggesting coinfections occur, and some cases of massive branchial henneguyosis may contain concurrent PGD lesions contributing to morbidity. These findings establish a case definition for a putative emerging, myxozoan-induced gill disease of farm-raised catfish with a proposed condition name of massive branchial henneguyosis of catfish (MBHC). Proliferative gill disease (PGD) in Channel Catfish Ictalurus punctatus and hybrid catfish (Channel Catfish × Blue Catfish I. furcatus) is attributed to the myxozoan Henneguya ictaluri. Despite evidence of decreased H. ictaluri transmission and impaired parasite development in hybrid catfish, PGD still occurs in hybrid production systems. Previous metagenomic assessments of clinical PGD cases revealed numerous myxozoans within affected gill tissues in addition to H. ictaluri. The objective of this study was to investigate the development and pathologic contributions of H. ictaluri and other myxozoans in naturally and experimentally induced PGD. Henneguya species-specific in situ hybridization (ISH) assays were developed using RNAscope technology. Natural infections were sourced from diagnostic case submissions in 2019. Experimental challenges involved Channel Catfish and hybrid catfish exposed to pond water from an active PGD outbreak, and the fish were sampled at 1, 7, 10, 12, 14, 16, 18, and 20 weeks postchallenge. Nine unique ISH probes were designed, targeting a diagnostic variable region of the 18S ribosomal RNA gene of select myxozoan taxa identified in clinical PGD cases. Partial validation from pure H. ictaluri, H. adiposa, H. postexilis, and H. exilis infections illustrated species-specific labeling and no cross-reactivity between different myxozoan species or the catfish hosts. After experimental challenge, mature plasmodia of H. ictaluri and H. postexilis formed in Channel Catfish but were not observed in hybrids, suggesting impaired or delayed sporogenesis in the hybridized host. These investigations also confirmed the presence of mixed infections in clinical PGD cases. Although H. ictaluri appears to be the primary cause of PGD, presporogonic stages of other myxozoans were also present, which may contribute to disease pathology and exacerbate respiratory compromise by further altering normal gill morphology. This work provides molecular confirmation and more resolute developmental timelines of H. ictaluri and H. postexilis in Channel Catfish and supports previous research indicating impaired or precluded H. ictaluri sporogony in hybrid catfish.

Background: Rosacea is a chronic facial skin disease in which persistent erythema is a significant clinical problem, often resistant to standard therapies. Intensive pulsating light (IPL) has become a recognised and effective method of treating erythema and telangiectasia. The latest recommendations emphasise the advantage of combining subjective clinical assessments with objective imaging analyses in monitoring therapy effects. Methods: A total of 20 patients with rosacea qualified for this study. They were subjected to three polychromatic light procedures (Lumecca, Inmode; wavelength of 515-1200 nm) at 21-day intervals. The skin condition was documented photographically, and the degree of erythema was assessed on the basis of the Clinician Erythema Assessment (CEA) scale and objective analysis of the skin texture, using the parameters of contrast and homogeneity of the grey level co-occurrence matrix (GLCM). Results: A series of three polychromatic light treatments yielded a significant clinical improvement in all patients. The mean CEA value decreased by 61.11%, whereas the GLCM contrast in all the analysed facial areas dropped by about 17%, and homogeneity increased by 4-5%. The effects persisted for at least three months after the treatments. A high correlation of CEA scale results with GLCM parameters (R = 0.81-0.94 for contrast; R = -0.77 to -0.83 for homogeneity) was observed. Conclusions: Three polychromatic light treatments proved to be a very effective method of reducing erythema in rosacea, confirmed by both clinical evaluation and objective imaging analysis. The effects of therapy were durable and clear. Integration of the subjective method (CEA) with GLCM analysis can be a path for future research and clinical practice in the assessment of erythematous skin lesions. Background/Objectives: "Ozempic face" is an aesthetic side effect associated with the use of the antidiabetic agent Ozempic (semaglutide), characterized by a prematurely aged and fatigued facial appearance due to rapid weight loss. Currently, treatment options for this condition are limited. In this study, we present our clinical experience with the BodyTite device, provided by InMode Italy S.r.l. (Rome, Italy). Materials and Methods: We report a case series involving 24 patients (19 women and 5 men, aged 27-65 years), treated with subdermal bipolar radiofrequency (Endotissutal Bipolar Radiofrequency) between 2023 and 2024. All patients underwent a minimum follow-up of 12 months. At the end of the follow-up period, patients rated their satisfaction on a from 0 to 10 scale, and an independent expert assessed the stability of clinical outcomes. Results: The majority of patients reported high satisfaction levels (≥8), which correlated with the independent expert's evaluation of treatment efficacy and result stability. The only observed adverse event was transient cutaneous erythema. Conclusions: "Ozempic face" is an increasingly common side effect associated with newer classes of antidiabetic medications. Although these drugs offer significant metabolic benefits, the accompanying facial volume loss and aging are often poorly tolerated by patients. Our findings suggest that subdermal bipolar radiofrequency represents a safe, low-risk, and cost-effective therapeutic option for the aesthetic management of Ozempic face. Autonomic nerves and ganglia that affect bladder sensation and detrusor contractility are present below the proximal urethra and trigone. Radiofrequency energy has been shown to potentially ablate/modulate these nerves in overactive bladder (OAB) patients. In this study, we intended to establish the safety and efficacy of transvaginal radiofrequency energy delivered via a vaginal Morpheus (Inmode) microneedling device in female patients with OAB. Women with known OAB, both primary and refractory as well as urge-predominant mixed urinary incontinence, were treated in the office setting using transvaginal detrusor nerve radiofrequency ablation to a depth of 7 mm.The primary outcome was the change in urge incontinence episodes on a 3-day voiding diary at 3 months after procedure. Secondary outcomes were the following at 1 and 3 months: the change in urinary frequency and incontinence, Incontinence Impact Questionnaire-7 (IIQ-7), Urinary Distress Inventory-6 (UDI-6), and Patient's Perception of Bladder Condition (PPBC). A pain assessment was collected immediately after the procedure and a Patient Global Impression of Improvement questionnaire was collected at 3 months. From 07/2023 to 02/2024, 32 were enrolled and 31 were followed for 3 months after treatment. Episodes of urgency incontinence, IIQ-7, UDI-6, PPBC, urinary frequency, and episodes of severe urinary urgency, had statistically significant improvement. Significant Analysis of Variance (ANOVA) testing ( P  < 0.001) was encountered with the IIQ-7, UDI-6, PPBC, urinary frequency, and urgency incontinence. No adverse events were encountered. Across all outcome metrics, the transvaginal detrusor nerve radiofrequency ablation for treatment of overactive bladder showed statistically significant improvements. Background: The techniques of choice used in the treatment of extensive vascular lesions of the face are methods based on high-energy light sources, such as lasers and IPL (intense pulsed light). The techniques commonly employed to detect blood vessel abnormalities in skin primarily rely on semi-quantitative or qualitative scales. Methods: The study was conducted on a group of 38 volunteers; a series of three treatments was performed using an IPL source (Lumecca, Inmode, Israel). The vessels' response to the high-energy light was verified using the following quantitative methods: mexametric measurements, hyperspectral imaging, and directional reflectance measurements. Results: In the mexameter measurement, statistically non-significant differences were obtained in the hemoglobin content in the skin condition prior to and following multiple intense pulsed light sessions. Studies performed using a hyperspectral camera showed that at a wavelength of 580 nm, the increase in skin reflectance after the treatment was statistically significant. Total directional reflectance measurements showed that at wavelengths of 400-540 nm and 480-600 nm, following the IPL treatment, the skin reflectance increased statistically significantly. Implementing three consecutive intense pulsed light procedures appears adequate to obtain a clinically satisfactory reduction in vascular changes in the facial skin. Mexametric measurements do not enable the assessment of the reaction of blood vessels to IPL. Conclusions: Hyperspectral imaging is an effective method for the quantitative assessment of skin vascular lesions. The best results in the assessment of vascular lesions using hyperspectral imaging are obtained at wavelengths of 420 nm and 580 nm. The hemispheric directional reflectance method allows for a quick, accurate, and repeatable assessment of vascular skin changes. Surgeons and providers in aesthetic medicine seek noninvasive devices that can be utilized for safe, efficient, and effective body contouring. Patient demand has propelled the development of novel devices that can simultaneously improve skin laxity, adipolysis along with stimulation of muscle hypertrophy. To determine the efficacy of body contouring after 3 treatments using the noninvasive Transform (InMode, Lake Forest, CA) device. A prospective, multicenter study was performed. Outcomes evaluated include: standardized caliper and ultrasound measurements of abdominal skin/soft-tissue thickness, waist circumference, histologic evaluation, patient comfort, and satisfaction assessments. Forty-four patients were successfully enrolled in the study and completed the series of 3 treatments which involved combined electrical muscle stimulation (EMS) and noninvasive bipolar radiofrequency (RF). Abdominal ultrasound measurements reveal a

Dry eye disease (DED), also known as dry eye syndrome, is a multifactorial ocular surface disease. The aim of this review is to present the details of currently approved and upcoming treatment options for DED in a nutshell. We conducted a thorough literature search using PubMed and searched US FDA website, clinicaltrials.gov, and data available in public domain for currently approved and upcoming treatment options for DED. Currently, the US Food and Drug Administration (FDA)-approved medical treatments for treatment of DED include cyclosporine formulations (RESTASIS® [cyclosporine 0.05% ophthalmic emulsion], VEVYE® [cyclosporine 0.1% ophthalmic solution], and CEQUA™ [cyclosporine 0.09% ophthalmic solution]), XIIDRA® (lifitegrast), a leukocyte function-associated antigen-1 (LFA-1)/intracellular adhesion molecule-1(ICAM-1) inhibitor, EYSUVIS™ (loteprednol etabonate ophthalmic suspension 0.25%), a corticosteroid, and MIEBO™ (perfluorohexyloctane ophthalmic solution), a semifluorinated alkane. TYRVAYA™ (varenicline solution nasal spray), a cholinergic agonist, is another formulation approved for the treatment of the signs and symptoms of DED. The medical devices approved for treating DED due to meibomian glands dysfunction (MGD) include Lumenis OptiLight™ (intense pulsed light [IPL] device), TearCare® system, and TearScience™ LipiFlow™ thermal pulsation system. Punctal plugs are another treatment option approved for management of DED. There are hundreds of clinical studies evaluating newer treatments for managing the signs and symptoms. Cyclosporine formulations TJO-087 (cyclosporine A nanoemulsion 0.08%), SCAI-001 eye drops (cyclosporine 0.01%, 0.02%) are being evaluated against RESTASIS® and other approved treatments. The potential treatments being assessed include IC 265, OK-101, PL9643, SYL1001 (tivanisiran), SHJ002, OXERVATE® (cenegermin-bkbj ophthalmic solution 0.002%), HBM9036 (tanfanercept ophthalmic solution), OCS-02 (licaminlimab), MIM-D3 (tavilermide ophthalmic solution 5%), AR-15,512, BRM421, reproxalap, and AZR-MD-001 (selenium sulphide ointment 0.5%). The pathophysiology of DED is complex and multifactorial; there is a need to understand it even deeper. The new treatments and different delivery systems seem promising and provide a hope of effective treatment for DED. The thickness and shade of a restoration will affect the transmission of light from the light-curing unit (LCU). This study determined the power (mW), spectral radiant power (mW/nm), and beam profile of different LCUs through various thicknesses and shades of a CAD-CAM resin composite (BRAVA Block, FGM). Five thicknesses: 0.5; 0.75; 1.0; 1.5, and 2.0 mm, in three shades: Bleach; A2 and A3.5 of a CAD-CAM resin (n = 5). Two single-peak LCUs: EL, Elipar DeepCure-S (3M Oral Care); and OP, Optilight Max (Gnatus), and one multiple-peak LCU: VL, VALO Grand (Ultradent), were used. The LCUs were positioned touching the surface of the BRAVA Block. The power and emission spectrum were measured using a fiberoptic spectrometer attached to an integrating sphere, and the beam profiles using a laser beam profiler. The effect of the material thickness on the light attenuation coefficients was determined. VL and EL delivered more homogeneous beam profiles than OP. The type of the BRAVA Block had a significant effect on the transmitted power, and wavelengths of transmitted light (p < 0.001). There was an exponential reduction in the power and emission spectrum as the thickness of the BRAVA Block increased (p < 0.001). The light transmission through the A2 shade was least affected by the thickness (p < 0.001). The attenuation coefficient was higher for the violet light and higher for A3.5 than the A2 or Bleach shades. No violet light from the VL could be detected at the bottom of 2.0 mm of the BRAVA Block. To analyze the effect of using the resin-based composite manufacturer's recommended exposure time on the degree of conversion (DC), Knoop hardness (KH), and elastic modulus (E) of conventional and bulk-fill resin-based composites (RBCs). Three resin-based composites (RBCs) were tested: Tetric EvoCeram Bulk Fill (TET), Opus Bulk Fill APS (OPU), and RBC Vittra APS (VIT). They were photo-activated in 2 mm deep, 6 mm diameter molds for their recommended exposure times of 10 seconds, 20 seconds, or 40 seconds from four light-curing units (LCUs). Two delivered a single emission peak in the blue light region (Optilight Max and Radii-Cal) and two delivered multiple emission peaks in the violet and blue region (VALO Cordless and Bluephase G2). After 24 hours of dry storage at 37°C in the dark, the KH (Kgf/mm2), E (MPa) and DC (%) at the top and bottom surfaces of specimens (n=5) were measured and the results analyzed by 2-way analysis of variance (ANOVA) followed by a Tukey test (α=0.05). The irradiance (mW/cm2) and spectral irradiance (mW/cm2/nm) from the LCUs were reduced significantly (8-35%) after passing through 2.0 mm of RBC (p<0.001). The DC at the bottom of VIT and TET was less than at the top surface (p<0.001). OPU had the same DC at the top and bottom surface (p=0.341). The KH and E values at the top surface of VIT and TET were substantially higher than at the bottom (p<0.001). OPU exposed for 40 seconds achieved higher mechanical properties than TET that was photo-activated for 10 seconds (p<0.001). The opacity of different bulk-fill RBCs changed differently during the polymerization; OPU became more opaque, whereas TET became more transparent. When exposed for their recommended times, the 2 mm thick RBCs that used Ivocerin or the APS photoinitiator system were adequately photo-activated using either the single or multiple emission peak LCUs (p=0.341). After 24 hours' storage, all the 2 mm thick RBCs photo-cured in 6 mm diameter molds achieved a bottom-to-top hardness ratio of at least 80% when their recommended exposure times were used. TET, when photo-activated for 10 seconds, achieved lower mechanical properties than OPU that had been photo-activated for 40 seconds. The change in opacity of the RBCs was different during photo-activation. Irradiance may decrease as the light-emitting diode (LED) is discharged. Therefore, the LED must be charged carefully to prevent the possibility of influencing the chemical, mechanical, and physical properties of composite resin. The aim of this study was to evaluate the influence of different light-emitting diode (LED) curing units and battery levels on the chemical, mechanical, and physical properties of composite resins. The irradiance for each cycle from full to completely discharged battery level was evaluated, for five different new cordless LED units: Optilight Color (Gnatus), Bluephase (Ivoclar), Valo (Ultradent), Radii Plus (SDI), and Radii Xpert (SDI). After the irradiance evaluation, composite resin specimens were prepared and light cured, while varying the battery level for each LED unit: high level (HL, 100%), medium level (ML, 50%), and low level (LL, 10%). The degree of conversion, diametral tensile strength, sorption, and solubility were also evaluated. Data were checked for homoscedasticity and submitted to two-way and three-way analysis of variance, depending on the test performed, followed by the Tukey test with a significance level of 95%. A negative correlation was found between irradiance and cycles of light curing, which was checked by the Pearson correlation test. Valo and Radii Xpert were not influenced by the battery level in any test performed. However, different battery levels for some LED units can influence the degree of conversion, diametral tensile strength, sorption, and solubility of composite resins. With the development of the light-emitting diode (LED) to photo-activate composite resin, greater intensities could be reached without greater elevation of temperature in the mass of the composite resin and in the d

Botulinum toxin (BT) is used therapeutically since the late 1980s. For many years, BT drugs were provided by a small group of manufacturers from Europe and the United States. As BT's use for aesthetic purposes surged, numerous new manufacturers entered the field, particularly from Korea. We want to give an overview about the rapidly expanding and diversifying BT landscape in Korea. Altogether, there are 15 Korean manufacturers of 19 BT drugs registered in Korea, mainly for aesthetic indications. There are 2 Class 1 drugs from 2 Korean manufacturers registered in Korea for export, domestic use and registered in the USA and Europe. These are PrabotulinumtoxinA (Daewoong/Evolus) and LetibotulinumtoxinA (Hugel/Croma Pharma). There are 12 Class 2 drugs from 10 Korean manufacturers registered in Korea for export and domestic use, including Neuronox®, the first Korean BT drug registered in 2006, NivobotulinumtoxinA/Innotox®, the world-wide first liquid BT type A preparation and Coretox®, the world-wide second BT drug without complexing proteins. Innotox® and Toxsta® are currently performing clinical studies in the USA. Additionally, there are 5 Class 3 BT drugs from 5 Korean manufacturers registered in Korea for export use only. 5 Korean manufacturers have 5 drug projects in Korea in advanced development phases. With this, Korea is now the country with the worldwide largest number of BT manufacturers and BT drugs. Gastric botulinum toxin therapy is gaining attention as a non-invasive treatment for obesity. However, existing studies show inconsistent results and standardized protocols remain lacking. We aimed to evaluate the efficacy and safety of a novel whole-stomach injection method emphasizing the antrum and fundus in obese patients in Japan. A total of 144 obese patients (mean age 42.3 years, mean BMI 30.3 kg/m²) underwent gastric botulinum toxin therapy at our institution between February 2023 and November 2024. Coretox (300-400 U) was injected endoscopically across the entire stomach, with increased concentration in the antrum and fundus. Patients were followed for six months post procedure. The primary outcome was the percentage of total body weight loss (%TBWL), and safety was assessed by the occurrence of complications per Clavien-Dindo classification. Mean %TBWL was 6.5% at one month, 10.2% at three months, and 12.2% at six months post treatment. No complications or adverse events were reported. The average procedure time was 5.7 minutes, and all patients completed follow-up as scheduled. We hypothesize that the observed efficacy may be partially attributed to our refined injection technique and individualized BMI-based dosage adjustment, although further controlled studies are needed to validate this approach. Gastric botulinum therapy using a novel full-stomach injection method focusing on the antrum and fundus was found to be both safe and effective in a Japanese obese population. This technique may offer a promising, minimally invasive option for obesity management. Further multicenter and long-term studies are warranted to validate and standardize this approach. The formation of neutralizing antibodies is a growing concern in the use of botulinum neurotoxin A (BoNT/A) as it may result in secondary treatment failure. Differences in the immunogenicity of BoNT/A formulations have been attributed to the presence of pharmacologically unnecessary bacterial components. Reportedly, the rate of antibody-mediated secondary non-response is lowest in complexing protein-free (CF) IncobotulinumtoxinA (INCO). Here, the published data and literature on the composition and properties of the three commercially available CF-BoNT/A formulations, namely, INCO, Coretox® (CORE), and DaxibotulinumtoxinA (DAXI), are reviewed to elucidate the implications for their potential immunogenicity. While all three BoNT/A formulations are free of complexing proteins and contain the core BoNT/A molecule as the active pharmaceutical ingredient, they differ in their production protocols and excipients, which may affect their immunogenicity. INCO contains only two immunologically inconspicuous excipients, namely, human serum albumin and sucrose, and has demonstrated low immunogenicity in daily practice and clinical studies for more than ten years. DAXI contains four excipients, namely, L-histidine, trehalosedihydrate, polysorbate 20, and the highly charged RTP004 peptide, of which the latter two may increase the immunogenicity of BoNT/A by introducing neo-epitopes. In early clinical studies with DAXI, antibodies against BoNT/A and RTP004 were found at low frequencies; however, the follow-up period was critically short, with a maximum of three injections. CORE contains four excipients: L-methionine, sucrose, NaCl, and polysorbate 20. Presently, no data are available on the immunogenicity of CORE in human beings. It remains to be seen whether all three CF BoNT/A formulations demonstrate the same low immunogenicity in patients over a long period of time. Botulinum neurotoxin type A (BoNT/A) causes muscle paralysis by blocking cholinergic signaling at neuromuscular junctions and is widely used to temporarily correct spasticity-related disorders and deformities. The paralytic effects of BoNT/A are time-limited and require repeated injections at regular intervals to achieve long-term therapeutic benefits. Differences in the level and duration of effectivity among various BoNT/A products can be attributed to their unique manufacturing processes, formulation, and noninterchangeable potency units. Herein, we compared the pharmacodynamics of three BoNT/A formulations, i.e., Botox® (onabotulinumtoxinA), Xeomin® (incobotulinumtoxinA), and Coretox®, following repeated intramuscular (IM) injections in mice. Three IM injections of BoNT/A formulations (12 U/kg per dose), 12-weeks apart, were administered at the right gastrocnemius. Local paresis and chemodenervation efficacy were evaluated over 36 weeks using the digit abduction score (DAS) and compound muscle action potential (CMAP), respectively. One week after administration, all three BoNT/A formulations induced peak DAS and maximal reduction of CMAP amplitudes. Among the three BoNT/A formulations, only Coretox® afforded a significant increase in paretic effects and chemodenervation with a prolonged duration of action after repeated injections. These findings suggest that Coretox® may offer a better overall therapeutic performance in clinical settings. Human serum albumin (HSA) has been widely used as a pharmaceutical excipient in Botulinum toxin serotype A (BoNT/A) products that are indicated for use in therapeutics and cosmetics. However, HSA as a human-derived material has some concerns, such as the potential risk of transmission of infectious agents, an insufficient supply, and difficulty in maintaining a certain quality. For those reasons, newly developed BoNT/A products (CORETOX®, Medytox, Inc., Republic of Korea) contained polysorbate 20, a non-human-derived excipient, to replace the HSA. However, most safety studies of polysorbate 20 have been conducted with non-invasive routes of administration, and thus there are a few studies on the safety of polysorbate 20 when administered intramuscularly. To secure the in vivo safety profile of polysorbate 20, a four-week repeated intramuscular dose toxicity study (0.02, 0.1, and 0.4 mg/kg, one injection every two weeks for a total of three injections) was conducted in 66 Sprague-Dawley (SD) rats. An intradermal irritation study was further conducted with 18 New Zealand White (NZW) rabbits. The toxicological evaluation of HSA (0.06 and 0.12 mg/kg) was also carried out as a comparative substance. Systemic and local toxicities were not observed in any of the SD rats or NZW rabbits based on clinical signs, body weight, hematology, clinical biochemistry, macroscopic findings on necropsy, histopathology of the injection site, and alle

Following Nonablative fractional Fraxel laser (NAFL), a well-established treatment for skin rejuvenation, immediate post-procedural care is essential to address any potential complications and accelerate the healing process. To evaluate the efficacy and patient satisfaction of a topical skincare regimen containing vitamin C, vitamin E, and ferulic acid-CE Ferulic serum (CEF) following NAFL treatment in the Chinese population. In this randomized, investigator-blinded, split-face, controlled trial, patients with mild-to-moderate facial photodamage were randomized to receive CEF treatment on one side of the face and normal saline (NS) on the other side immediately after the NAFL procedure and daily during the 7-day follow-up. The primary endpoint was the change from baseline in erythema score on Day 7, with key secondary endpoints including changes from baseline in erythema index (EI), melanin index (MI), transepidermal water loss, skin hydration, skin sebum content, scabbing, edema, overall patient satisfaction, and post-procedure pain. In total, 50 patients (female 45/50) were enrolled in this study, with a mean age of 31.6 years. The mean change from baseline in erythema score was significantly lower on the CEF side than on the NS side on Day 7 post-NAFL treatment (0.04 ± 0.40 vs. 0.18 ± 0.48, p = 0.011). The CEF side also exhibited improved changes in EI, MI, and skin hydration, as well as higher overall satisfaction and less pain compared with the NS side. Applying CEF after NAFL treatment reduced erythema progression, maintained skin hydration, and promoted the healing process compared with NS. Chinese Clinical Trial Registry: ChiCTR2300069246. Multicentric Castleman's disease (MCD) with cutaneous involvement has rarely been discussed in dermatologic literature, with few reports. Cutaneous lesions in MCD may induce deep scars, causing a significant impact in the daily life of the patients. The treatment of Castleman's disease (CD) is usually a challenge, especially in case of cutaneous involvement. We report the case of a 35-year-old Caucasian man with a 3-year-old history of MCD with cutaneous involvement that we treated with a combined therapy characterized by siltuximab and 1,927 nm fractional laser. The patient showed a therapeutic response, characterized by a reduction of systemic symptoms and cutaneous manifestations. We believe that the combination of siltuximab and 1,927 nm fractional laser might have a synergistic beneficial role in patients with cutaneous iMCD and maximize esthetic outcomes. Anyway, additional evidence is needed to validate our findings. Microbotox technique, intradermal injection of microdroplets of botulinum toxin, is a favorable rejuvenation approach in subjects who prefer more natural appearance. To determine the best injection techniques (dosage, concentration, as well as number and location of injection points), efficacy and side effects of this innovative technique for facial rejuvenation. We conducted a search in Pubmed, Embase, Web of Science, and Google Scholar databases from conception until October 2021 with keywords "microbotox" OR "mesobotox" OR "intradermal injection" AND "botulinum toxin" AND "rejuvenation" AND "wrinkle" AND "face-lift." Twenty articles were included in this review article. Different types of formulation including onabotulinum toxin A (OBA), abobotulinum toxin A (ABO), and incobotulinum toxin A (IBA) were used. The most used concentrations were 10-20 u/cc of OBA. Number of injection points varied from 4 (forehead and periorbital areas) to 999 (entire face) with 2 mm to 2 cm apart. Adjuvant treatment modalities were cross-linked hyaluronic acid, intense pulsed laser, and Fraxel laser. Most studies reported the initial results appeared after 5-14 days of procedure, lasting for nearly 3-6 months. Microbotox is an efficient and attractive method for facial rejuvenation, mid-lower face-lifting, and fine wrinkles reduction in forehead, periocular, and cheek regions, especially in younger-aged subjects. Furthermore, it is a suitable treatment for neck rejuvenation and recontouring of lower mandibular border, particularly in older subjects with marked skin laxity. The Fraxel Dual laser system (Solta Medical, Inc., Bothell, WA) contains a 1,550 and 1,927 nm wavelength single handpiece with different indications for each wavelength. To discuss treatment setting recommendations and best practices for select on-label and investigational applications of the 1,550 and 1,927 nm dual laser system. Eight board-certified dermatologists with 10 or more years of experience with the 1,550 and 1,927 nm laser system completed an online survey about their clinical experience with the system and then participated in a roundtable to share clinical perspectives and best practices for using the laser system. For all Fitzpatrick skin types, treatment recommendations were described for selected approved indications for the 1,550 and 1,927 nm laser system, including both lasers in combination. Treatment recommendations were also reached for investigational applications with the 1,550 nm laser and 1,927 nm laser. Best practices for using the lasers during the treatment session to achieve optimal outcomes and decrease the post-treatment recovery time were compiled. The 1,550 and 1,927 nm dual laser system is effective for a wide range of aesthetic and therapeutic applications, on and off the face and across all Fitzpatrick skin types. Following our survey, we can appreciate that a variety of laser platforms exist to rejuvenate the skin by resurfacing the outer layer of the skin as well as heating the lower layers of the dermis. Based on reliable clinical effectiveness and a limited side effect profile, we can confirm that nonablative fractionated technologies greatly improve the appearance of lentigines, rhytids; eliminate sun damage, attenuate scarring due to acne and other causes; and treat hyperpigmentation. The Fraxel (Solta Medical) laser system delivers pulses across a wide range of density and energy levels. We determined that when increasing the pulse energy this led to an increase in thermolysis microzone depth and width without damaging the surrounding tissue. Due to its performance and various clinical applications, Fraxel laser can be optimally considered to be the gold standard for skin rejuvenation. Sebaceous hyperplasia (SH) is a common skin presentation in adults. Due to their unwanted yellow papular appearance, patients may desire their removal. Although several treatment modalities have been reported, the full range and efficacy of options are unclear. To determine the efficacy of laser modalities in the treatment of SH. The authors will also specifically assess the efficacy, recurrence rate and side effect profile of SH treatment with Er:YAG wavelength using a variable long pulsed (VLP) Er:YAG laser (SP Dynamis Fotona laser, Ljubljana, Slovenia) Methods & Materials: A comprehensive literature search was performed through PubMed, EMBASE, and Web of Science, using the search terms [(sebaceous hyperplasia)] and [(laser[s], Er:Yag, Er:Glass, Fraxel, CO2, PDL, Pulse dye laser, Diode, Xe-Cl, Excimer, Argon, KTP, Ruby, Alexandrite or Nd:YAG)]. The search yielded a total of 119 results and 8 were identified as relevant to this reviewResults: Pulse dye laser (PDL) provides a wide range of treatment results from complete reduction to flattening of the SH without significant adverse events; recurrence rates were unreported. Short PDL showed faster treatment response than long PDL. CO2 laser can produce considerable positive cosmetic outcomes with marked clinical improvement without any recurrence, but significant adverse effects have been reported. The 1450-nm diode laser has been described to produce good (75%) clinical improvement and lesion shrinkage ranging from 50% to greater than 75% without lasting adverse effects. In

Facial aging, marked by skin laxity, wrinkling, and dyspigmentation, remains a common aesthetic concern. Few studies have investigated combination approaches to treat these concomitant components of aging. To investigate the effect of combining monopolar radiofrequency with fractional nonablative diode laser treatments to improve skin laxity, wrinkling, and dyspigmentation. A prospective, single-arm study enrolled 20 females with mild to moderate facial skin laxity and photoaging. Subjects underwent a sequence of one monopolar radiofrequency treatment (Thermage FLX, Solta, Bausch Medica, Bothell, WA) followed by 4 fractional 1440-/1927-nm nonablative diode laser treatments (Clear + Brilliant Touch, Solta, Bausch Medica). Assessments included clinical evaluations, blinded photographic assessments, and patient satisfaction scores. At the 6-month follow-up, a significant improvement was observed in Skin Laxity Grading Scale and Glogau Classification of Photoaging scale scores (1.65 ± 0.49-1.30 ± 0.47, p = .039, and 1.85 ± 0.36-1.35 ± 0.49, p = .00082, respectively). Blinded reviewers correctly identified 67% of post-treatment photographs, and 77% of participants were considered responders. No serious adverse events occurred. Monopolar radiofrequency combined with fractional diode led to significant efficacy, suggesting a safe and promising strategy for addressing facial skin laxity, wrinkles, and dyspigmentation. The aim of this questionnaire-based study was to measure the level of appreciation, practice patterns, and side effects of monopolar radiofrequency treatment among Korean dermatologists practicing the most updated monopolar radiofrequency device (Thermage FLX, Thermage Inc., Hayward, California). According to a total of 52 surveys analyzed, this latest device (Thermage FLX) was considered more effective (57.4%), faster with reduced treatment time (66.0%), and more painful (25.5%) compared with Thermage CPT. Asians in their 40s were considered to benefit most and skin thickness continued to be the most important determinant in terms of responsiveness to Thermage FLX. The interval between treatments was mainly 1 year (51.9%) with the 600 REP 4 cm2 new total tip being preferred by 86.5% of Thermage FLX users. The treatment energy and the complication rate of Thermage was lower than what we reported in 2017 and 2011 which is likely due to the optimized energy delivery of Thermage FLX and the subsequent gentle treatment. We hope our updated data enable dermatologists to better utilize monopolar radiofrequency in their practice.

To date, no definitive treatment exists for rosacea. Phototherapies, including intense pulsed light (IPL), have been reported to reduce its characteristic features of erythema and telangiectasias. This multicenter, retrospective study reviewed the charts of 82 patients with vascular and pigmented rosacea who underwent treatment with the Harmony XL Pro VL/PL Cooled Applicator. Lesion coverage was assessed from photographs taken before and 3-4 months after the last treatment session. Physicians assessed aesthetic improvement using the 5-point Global Aesthetic Improvement Scale. Patients rated pain experienced during the session and satisfaction with outcomes. Treatment safety was monitored throughout. A total of 82 patients with rosacea underwent up to four IPL treatment sessions. Mean patient age was 41.9 ± 15.2 years, and most were female (84.1%), with skin type II or III (96.1%) and with facial rosacea (93.9%). Clearance of > 75% was achieved in 69.5% of the patients, and the remaining 30.5% achieved 51%-75% clearance. Physician-rated aesthetic improvement was optimal (64.6%) or good (34.1%); minimal change was reported for one lesion. Skin type III was associated with 3.59 times higher odds of achieving high clearance compared to skin type I or II (95% CI: 1.2-11.3). Patients were mostly very highly (95.1%) or highly satisfied (3.7%) with treatment outcomes. Most patients reported low (39.0%) to medium (46.3%) pain during treatment. Apart from a blister reported by one patient, no adverse events were reported. IPL is a safe, effective, and versatile light-based modality for the treatment of vascular rosacea lesions in individuals of skin types I-III. Vascular lesions of the lower extremities and face, such as varicose veins and telangiectasias, are a common dilemma for the dermatologist. In recent years, laser therapy has emerged as a viable treatment option for these vascular anomalies. Although there are several types of lasers, the 1064-nm Nd:YAG in particular is popularly selected for its safety profile and versatility. The longer 1064 nm wavelength penetrates deeper into the skin while also being less absorbed by hemoglobin and melanin, thus resulting in minimized damage to surrounding structures and less pigmentation changes. The new LP1064 applicator on the Harmony XL Pro Device is one such laser. Numerous publications have corroborated the efficacy of 1064 nm Nd:YAG lasers. These studies cite at least over 75% of patients experiencing significant improvement in common vascular lesions. Efficacy of this laser is also seen for other vascular lesions such as port wine stains, hemangiomas, venous lakes, poikiloderma of Civatte, and angiokeratomas. Overall, the reported studies also show a low incidence of adverse events. The 1064 nm Nd:YAG laser, such as the Harmony LP1064 applicator, is a safe and effective tool to treat vein anomalies of the face and leg. Although commonly used for vein ablation, it has demonstrated a robust response in other indications as well. To evaluate the safety and efficacy of a specific treatment protocol using a new and improved non-ablative fractional high-power 1064-nm Q-switched Nd:YAG laser for face and neck rejuvenation. Sixteen women, aged 30 to 60 years old, were selected to undergo three consecutive treatment sessions with this new laser at maximum energy (2,400 mJ/pulse, Clear Lift laser®-Harmony XL-Pro, Alma Lasers Ltd.). Face and neck were treated in eight patients, respectively. Each treatment used the same protocol. The efficacy was evaluated by the therapist (TS), the patient (PS), and two separate independent experts who were blind to the study (E1 and E2). According to E1 and E2, the mean reduction in signs of skin aging on a Global Esthetic Improvement Scale was 30-40%. Using a 0-10 points scale, TS and PS mean (range) satisfaction rates were 9.0 (8-10); 9.2 (6-10) for the face and 8.7 (8-10); 8.0 (3-10), for the neck, respectively. The procedure was practically painless, no significant adverse effects were observed, and the patients returned to their daily and work activities without downtime. This laser was safe and effective for face and neck minimally invasive rejuvenation, with excellent results using our usual routine use conditions. Introduction: Acne vulgaris is a common skin disorder with a significant impact on patients' quality of life. There is currently no treatment designated to treat acne lesions and scars concurrently. However, mid-infrared lasers may promote neocollagenesis within atrophic scars, while exerting a beneficial effect on acne lesions. Objectives: To determine the safety and efficacy of an integrated cooling-vacuum-assisted non-fractional 1540-nm Erbium:Glass laser for the treatment of acne lesions and scars. Patients and Methods: Twenty-two patients (8 male, 14 female) with mild-to-moderate acne and moderate-to-severe acne scars were included. Patients were treated using a non-fractional 1540-nm Er:Glass laser (Harmony XL™, Alma Lasers Ltd.). Acne lesions and scars were exposed to 3-4 stacked pulses emitted at a rate of 3Hz for up to two passes per treatment session (spot size, 4 mm; fluence, 400-600 mJ/pulse), receiving overall 3-7 treatments with 2-3-week intervals. Patients were followed-up one and three months following their last treatment. Clinical evaluation including (i) overall aesthetic appearance, (ii) acne lesions, and (iii) acne scars, assessed independently by two dermatologists and graded on a scale of 0 (exacerbation) to 4 (76-100 percent improvement); and (iv) pain perception, adverse effects and patients’ satisfaction. Results: All but one patient completed treatment and follow-up and had moderate-to-significant improvement in all outcomes (overall aesthetic appearance, mean 3.9 [1 month] and 3.75 [3 month] improvement; acne lesions, 3.5 [1 month] and 2.3 [3 month] improvement; scarring 4 [1 month] and 4.2 [3 month] improvement). Pain and adverse effects were mild and transient. Patients' mean satisfaction was 4.2. Conclusion: Cooling-vacuum-assisted 1540 nm laser is a safe and effective modality for the simultaneous treatment of acne lesions and scars. The Q-switched 1064-nm laser is associated with rapid vaporization and thermal expansion stresses leading to skin mechanical damage and is typically used for correction of exogenous and endogenous deep pigmentation. Giving the common place of fractional, infrared-domain milliseconds non-ablative lasers in aesthetic dermatology, a novel non-ablative fractional Q-switched 1,064-nm laser was studied for photoaged skin concerns. Ten healthy female subjects (Age range: 35-53 years, mean: 44.3) and skin types I-IV were diagnosed with mild-to-moderate facial photo-damage, hyper-pigmentation, telangiectasia, laxity, skin roughness, and actinic keratosis. Subjects were treated with a new non-ablative fractional Q-Switched 1,064-nm Nd: YAG laser (Harmony XL, Alma Lasers Ltd.). Treatments consisted of four sessions at 2-4 week intervals. Follow-up (FU) visits were 1 and 3 months following the final treatment. Utilizing the Glogau scale, six Subjects were graded Type II (means wrinkles in motion), and four Subjects were graded Type III (means wrinkles at rest) at Baseline. At the FU2, 3-month post final treatment, 60% of the subjects were graded with at least a one-point improvement in the overall Glogau global assessment. Between baseline and FU2, Investigator assessments showed the following improvements: Hyperpigmentation 70%, Telangiectasias 80%, Laxity 80%, Tactile Roughness 60%, and actinic keratoses 60%. Pain assessment was reported between 0 and 2 in all treatments (scale 0-10). Of expected side effects, erythema was most common, occasionally being reported as high as a 2(scale 0-10). No unexpected adverse effects were reported. The non-ablative fractional Q-Switched 1,064-nm Nd: YAG laser is safe and effective in impr

Hidradenitis suppurativa (HS) remains a therapeutically challenging disease despite expanding research and evolving systemic treatments. Energy-based modalities, such as fractional microneedling radiofrequency (FMR), are being increasingly explored as novel treatment options. To evaluate the real-world efficacy and safety of Morpheus8-based FMR treatment in patients with HS. This retrospective analysis included 25 HS patients treated at a tertiary dermatology center. Seventeen patients who completed ≥ 2 FMR sessions were included in the efficacy analysis. Outcomes were assessed by the International Hidradenitis Suppurativa Severity Score System (IHS4) and IHS4-55 (≥ 55% reduction). High-frequency ultrasound (HFUS) was used in selected cases to assess treatment response and inflammatory changes. Sixteen of the 17 patients (94.1%) evaluated for efficacy showed clinical improvement, and nine (52.9%) achieved an IHS4-55 response. The mean IHS4 reduction was 4.6 ± 2.5. The highest response rates were observed in the face, chest, and gluteal regions, while groin and thigh showed the lowest. HFUS confirmed a reduction in inflammation. Treatment was generally well tolerated, with pain cited as the most common reason for discontinuation in 3 of 25 patients (12%). FMR appears to be a safe and effective treatment option for patients with moderate-to-severe HS, including those with refractory disease and lesions in anatomically challenging areas. Clinical outcomes in our cohort were comparable to those reported for advanced systemic agents and other technology-based interventions. These findings support FMR's potential role in personalized HS management - either as a standalone intervention or in combination with systemic or procedural treatments. This study evaluated a novel approach combining low-energy Morpheus8 radiofrequency (RF) microneedling and nanofat grafting for facial rejuvenation, aiming to preserve adipose tissue while enhancing skin quality. A retrospective analysis was conducted on 20 patients (aged 20-45 y) treated with nanofat injections immediately after low-energy RF microneedling. Outcomes included Global Aesthetic Improvement Scale scores and nonsurgical parameters (pore visibility, skin luminosity, and fine wrinkles), assessed at 1, 3, and 12 months posttreatment. Pretreatment Global Aesthetic Improvement Scale scores (mean = 3.35, SD = 0.61) showed significant improvement posttreatment (mean = 1.76, SD = 0.87; P < 0.001). Sustained enhancement was observed at 3 months (mean = 1.52, SD = 0.63; P < 0.001), with 85% of patients rated as "very much improved." Blinded evaluations confirmed visible reductions in pore visibility, increased skin luminosity, and diminished fine wrinkles in nonsurgical regions (malar, perioral). No adverse events were reported. The combination of low-energy RF microneedling and nanofat grafting synergistically improves facial aesthetics by targeting regenerative and structural aging markers. Specific enhancements in nonsurgical regions underscore the value of this adjunctive approach. Larger controlled studies are warranted to establish causality. In his practice, the author has been using noninvasive devices, including Evolve X-radiofrequency-based procedure for tightening of the skin, melting of the subdermal fat deposits and muscle stimulation, all done simultaneously together and truSculpt flex-electrical muscle stimulation. Minimally invasive procedures include BodyTite, FaceTite, and AccuTite, radiofrequency-based procedures for permanent fat destruction and tightening of the skin. Morpheus8 and Morpheus8 Body are radiofrequency based-procedures for tightening of the skin. VASERlipo is an ultrasound-based procedure for liposuction and muscle definition. Vibrational type of liposuction has been used for the purpose of liposuction and muscle definition in combination with VASERlipo. A subset of facelift patients have premature redevelopment of skin laxity in the lower face and neck. Many patients seek alternatives to revision facelifts to avoid high risks and costs. Radiofrequency-assisted lipolysis (RFAL) with Radiofrequency (RF) microneedling may be alternative minimally invasive options. To evaluate the efficacy of radiofrequency energy devices for treatment of premature jowl and neck skin laxity following facialplasty. This is a single-center, prospective study of patients seeking treatment for jowl and neck skin laxity 1-5 years following facialplasty. Treatment was performed with the InMode radiofrequency AccuTite® and Morpheus8® systems. Study duration was 12 months with 6 months of follow-up. Endpoints included improvement in skin tightening assessed by blinded investigators, and investigator and subject assessment of skin appearance. Subjects also rated satisfaction with treatment and pain levels. The study protocol was completed by nine patients. Based on investigator evaluations, 33% had marked improvement at 3 months, which increased to 55% at 6-month postprocedure. Patient-reported improvement was "markedly improved" in 67%, "moderate improvement" in 11%, and "slight improvement" in 22% at 3 months. Overall patient satisfaction was rated as "very satisfied" by 33% and "satisfied" by 67% at 3 months. There were no adverse events reported. The results of this study provide supporting evidence that RFAL technology can provide a safe, minimally invasive, and effective treatment for skin laxity in the jowls and neck in patients who desire further correction after undergoing primary facelift. Noninvasive and minimally invasive treatments are increasingly supplanting, or complimenting, abdominoplasty. For optimal delivery of patient care and to maintain a dominant share of the body-contouring market, plastic surgeons need to embrace these new technologies. High capital purchases, costly disposables, maintenance fees, lack of experience, conflicting anecdotal reports, energy-related complications, marketing hyperbole, and rapid obsolescence are formidable barriers to this adoption. Receptive plastic surgeons may be best served by accepting brief short-term retrospective reports by reputable innovative body contouring surgeons who present a succinct and clinically supported message.

Henneguya sp. is a crucial myxosporean parasite known to cause milky flesh or tapioca disease in the freshwater fish population, leading to heavy mortality. Studies to investigate its host range and to monitor their prevalence in wild and aquacultured fish are necessary. The infected orange-spotted snakehead (Channa aurantimaculata) fish samples showing clinical signs such as severe ulceration and open wounds on the mouth and operculum were collected from an ornamental fish-rearing unit in Chennai, Tamil Nadu. The sample was diagnosed with myxosporean infection by microscopic observation, morphological records and DNA sequencing followed by phylogenetic analysis. The Henneguya infection was identified in C. aurantimaculata for the first time. Necropsy of the infected fish revealed characteristic multifocal whitish-yellow, oval-shaped cysts measuring 3-5 mm in length on the liver and spleen. The wet mount of cysts showed numerous mature Henneguya spores that were uninucleate, elongated, lenticular and ellipsoidal with the bluntly rounded anterior end gradually tapering off to the posterior with a caudal elongation. The spore body measured 12.1 ± 0.9 μm (10.1-14.7 μm) × 7.1 ± 0.6 μm (5.3-8.5 μm) with two slightly unequal pyriform polar capsules of 6.1 ± 0.5 μm (5.1-7.4 )× 2.5 ± 0.4 μm (1.6-3.9) (large); 6.0 ± 0.4 μm (5.2-6.4) × 2.5 ± 0.3 μm (1.7-3.1) (small) and a caudal elongation of 16.1 ± 1.2 μm in length. The parasite was confirmed to be a Henneguya sp. by PCR amplification of SSrRNA followed by gene sequencing. The sequence generated was submitted in the GenBank under accession number PP852214.1 The maximum likelihood analysis revealed that the obtained sequence is a close relative of H. exilis with pairwise sequence variation of 3.3% and a homology of 99.04%. The findings highlight the potential impact of Henneguya sp. on ornamental fish health, underscoring the need for vigilant monitoring and management in India. Proliferative gill disease (PGD), caused by the myxozoan Henneguya ictaluri, has been the most notorious parasitic gill disease in the US catfish aquaculture industry. In 2019, an unusual gill disease caused by massive burdens of another myxozoan, Henneguya exilis, was described in channel (Ictalurus punctatus) × blue (Ictalurus furcatus) hybrid catfish. Targeted metagenomic sequencing and in situ hybridization (ISH) were used to differentiate these conditions by comparing myxozoan communities involved in lesion development and disease pathogenesis between massive H. exilis infections and PGD cases. Thirty ethanol-fixed gill holobranchs from 7 cases of massive H. exilis infection in hybrid catfish were subjected to targeted amplicon sequencing of the 18S rRNA gene and compared to a targeted metagenomic data set previously generated from clinical PGD case submissions. Furthermore, serial sections of 14 formalin-fixed gill holobranchs (2 per case) were analyzed by RNAscope duplex chromogenic ISH assays targeting 8 different myxozoan species. Targeted metagenomic and ISH data were concordant, indicating myxozoan community compositions significantly differ between PGD and massive branchial henneguyosis. Although PGD cases often consist of mixed species infections, massive branchial henneguyosis consisted of nearly pure H. exilis infections. Still, H. ictaluri was identified by ISH in association with infrequent PGD lesions, suggesting coinfections occur, and some cases of massive branchial henneguyosis may contain concurrent PGD lesions contributing to morbidity. These findings establish a case definition for a putative emerging, myxozoan-induced gill disease of farm-raised catfish with a proposed condition name of massive branchial henneguyosis of catfish (MBHC). Proliferative gill disease (PGD) in Channel Catfish Ictalurus punctatus and hybrid catfish (Channel Catfish × Blue Catfish I. furcatus) is attributed to the myxozoan Henneguya ictaluri. Despite evidence of decreased H. ictaluri transmission and impaired parasite development in hybrid catfish, PGD still occurs in hybrid production systems. Previous metagenomic assessments of clinical PGD cases revealed numerous myxozoans within affected gill tissues in addition to H. ictaluri. The objective of this study was to investigate the development and pathologic contributions of H. ictaluri and other myxozoans in naturally and experimentally induced PGD. Henneguya species-specific in situ hybridization (ISH) assays were developed using RNAscope technology. Natural infections were sourced from diagnostic case submissions in 2019. Experimental challenges involved Channel Catfish and hybrid catfish exposed to pond water from an active PGD outbreak, and the fish were sampled at 1, 7, 10, 12, 14, 16, 18, and 20 weeks postchallenge. Nine unique ISH probes were designed, targeting a diagnostic variable region of the 18S ribosomal RNA gene of select myxozoan taxa identified in clinical PGD cases. Partial validation from pure H. ictaluri, H. adiposa, H. postexilis, and H. exilis infections illustrated species-specific labeling and no cross-reactivity between different myxozoan species or the catfish hosts. After experimental challenge, mature plasmodia of H. ictaluri and H. postexilis formed in Channel Catfish but were not observed in hybrids, suggesting impaired or delayed sporogenesis in the hybridized host. These investigations also confirmed the presence of mixed infections in clinical PGD cases. Although H. ictaluri appears to be the primary cause of PGD, presporogonic stages of other myxozoans were also present, which may contribute to disease pathology and exacerbate respiratory compromise by further altering normal gill morphology. This work provides molecular confirmation and more resolute developmental timelines of H. ictaluri and H. postexilis in Channel Catfish and supports previous research indicating impaired or precluded H. ictaluri sporogony in hybrid catfish.

This study aims to shed light on the transformative potential of artificial intelligence (AI) in the early detection and risk assessment of non-communicable diseases (NCDs). Bibliometric analysis. Articles related to AI in early identification and risk evaluation of NCDs from 2000 to 2024 were retrieved from the Scopus database. This comprehensive bibliometric study focuses on a single database, Scopus and employs narrative synthesis for concise yet informative summaries. Microsoft Excel V.365 and VOSviewer software (V.1.6.20) were used to summarise bibliometric features. The study retrieved 1745 relevant articles, with a notable surge in research activity in recent years. Core journals included Scientific Reports and IEEE Access, and core institutions included the Harvard Medical School and the Ministry of Education of the People's Republic of China, while core countries comprised China, the USA, India, the UK and Saudi Arabia. Citation trends indicated substantial growth and recognition of AI's impact on NCDs management. Frequent author keywords identified key research hotspots, including specific NCDs like Alzheimer's disease and diabetes. Risk assessment studies demonstrated improved predictions for heart failure, cardiovascular risk, breast cancer, diabetes and inflammatory bowel disease. Our findings highlight the increasing role of AI in early detection and risk prediction of NCDs, emphasising its widening research impact and future clinical potential. Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired treatable autoimmune disorder. Due to limited availability and affordability of IV immunoglobulins and therapeutic plasma exchange in Pakistan, oral immunosuppressive drugs (ISDs) are used despite limited role in literature. The study aimed to determine the response to ISDs in CIDP patients by assessing the frequency of remission, reduction of disability using a neuropathy related disability score called Inflammatory Neuropathy Cause and Treatment score (or INCAT score), as well as reduction in steroid maintenance dose. The retrospective observational study of six months duration (May to October, 2020) was carried out in Aga Khan University Hospital, Karachi, Pakistan. Medical record of all the patients with idiopathic CIDP taking oral ISDs in last five years was selected which included bio-data, clinical signs and symptoms, medication details, and INCAT scores. Descriptive statistics were described i.e. frequency, percentages, mean/standard deviation using Microsoft Excel v.2021. Out of thirteen patients, Azathioprine was used in nine, Mycophenolate mofetil in two and Cyclosporine in two, with remission (INCAT score improvement ≥ 1) achieved in eight, one and zero patients respectively. Duration of ISDs ranged from three to twenty-four months (average 15.8 months). Patients with monoclonal paraproteinemia and prior exposure to ISDs had a poor response to the introduction of subsequent ISDs. The study describes preliminary experience of the potential role of relatively cheaper and more convenient oral ISDs (especially Azathioprine) as an alternative or sparing agent to first line agents for CIDP and sets the stage for larger scale studies and randomized controlled trials. The aim of this study was to identify and appraise the bibliometric properties of top 100 most-cited articles on regenerative periodontics surgery (RPS). The bibliometric research technique was conducted using a dataset comprising the 100 highly cited articles obtained from Elsevier's Scopus database on RPS. Information regarding the growth of articles by year, number of citations, citations per year, study design, study field, modalities, journals, authors, and countries were extracted for each article. Microsoft Excel (v.16) was utilized for data evaluation and tabulation. These articles on RPS were published over a span of 45 years, from 1975 to 2019, with citation metrics ranging from 144 to 820. Out of the 422 participating authors, 82% contributed to a single article. The 100 most cited articles on RPS were published in 45 years from 1975 to 2019 and number of citations ranged from 144 to 820. Out of the 422 participating authors, 82% contributed in a single article.. The study design with the highest number of cited articles was laboratory/animal studies. Others/not specified was the preferred modality, followed by infrabony modality. The Journal of Periodontology published about one-fourth of the articles, with W. V. Giannobile emerging as the most productive author. Among the 100 most-cited articles on RPS, authors from 25 different countries contributed, with the United States producing half of the articles (n = 51). Bibliometric investigation revealed that the most cited papers published before 2000 had higher citation counts due to their longer period of exposure. The ratio of authors per article increased after the year 2000. Infrabony emerges as a trending topic in RPS, with laboratory/animal studies, clinical trials, and literature reviews being the most frequently employed study designs. To study the impact of reorganization of European hospitals during the most severe phase of the SARS-CoV-2 pandemic on standards of care and early outcomes in patients with periprosthetic fractures. We reviewed available data collected from 14 hospitals in Northern Italy during the quarantine period between March 9 and May 4, 2020. The study included all patients admitted to emergency departments with periprosthetic fractures and scheduled for surgery within a 2-month period. Periprosthetic fractures were classified according to the Uniform Classification System (UCS). Distribution normality was tested using the Kolmogorov-Smirnov test. Accordingly, data were described as non-parametric. Statistical analysis was performed using the Microsoft Excel v. 16.0. In total, 1390 patients admitted to the Department of Orthopedics and Traumatology for emergency care throughout the follow-up period including 38 (2.7%) ones with periprosthetic fractures. There were 12 (31.5%) men and 26 (68.5%) women. Mean age was 81 years (range 70-96). Screening for SARS-CoV-2 by swab was performed in 23 out of 38 patients (60.5%) at admission. It was positive in 2 (5.3%) cases. Three out of thirty-eight patients (7.9%) were diagnosed with COVID-19 due to clinical signs. Of these, 2 patients were diagnosed with COVID-19 before surgery, 3 patients - after surgery. Although the study period coincided with quarantine, the number of admissions for periprosthetic fractures (3%) was similar to that in 2019 and accounted for 3% of the total number of visits to the traumatology and orthopedics departments. The study revealed no obvious changes in hospitalizations for periprosthetic fractures despite social restrictions during the first wave of the COVID-19 pandemic. In emergency, hospitals were still able to provide standard care for patients with periprosthetic fractures despite significant amount of resources redirected for the pandemic.

The manual identification of dental implant systems on radiographs is time-consuming, operator-dependent, and prone to diagnostic inaccuracies, particularly for patients where clinical documentation is lacking. The increasing variety of implant designs further complicates identification in prosthetic and surgical practice. The purpose of this study was to develop and evaluate a deep learning-based model for the automated identification of 7 implant systems (Adin, Dentium, Dionavi, Make It Simple (MIS), Nobel, Noris, and Osstem) using panoramic radiographs and periapical radiographs in an effort to enhance diagnostic efficiency and support clinical decision-making in prosthodontic care. A total of 4677 anonymized radiographic images with 8189 implants were curated and annotated using Roboflow with bounding boxes outlining fixture components. The preprocessing involved normalization, resizing to 640×640 pixels, and geometric augmentation (rotation, cropping, and blurring) to handle class imbalances. You Only Look Once (YOLO) v10 architecture, implemented with PyTorch, using CSPDarknet and PANet for multiscale feature fusion, was used to optimize real-time detection. Transfer learning used pretrained weights, with training for over 500 epochs (batch size: 32) on NVIDIA T4 GPUs. Data partitioning involved an 80:10:10 ratio (training: validation: testing), with performance evaluated using precision, recall, F1-score, and mean average precision (mAP). The model achieved a mAP of 98.3%, with mean precision, recall, and F1-score values of 93%, 86%, and 89%, respectively. Osstem implants demonstrated maximum discriminability (99% precision, 95% recall). In contrast, Nobel implants exhibited low recall (72.7%), attributed to the sparsity of the dataset (564 samples for Nobel compared with 2320 for Osstem) and similar radiopacity patterns. The YOLOv10 model demonstrated good performance in identifying dental implants, showing clinical promise for minimizing prosthetic mismatches. Subject to ethics and regulatory approvals, additional improvements involving 3-dimensional imaging and heterogeneous datasets may add precision and validate artificial intelligence as an evidence-based advance in implant dentistry. Implant identification is a pressing concern in dental implantology, and artificial intelligence (AI) has been evaluated for this purpose. YOLO, a state-of-the-art object detection model, is suitable for medical imaging; therefore, this study assessed YOLOv11-the latest iteration-for identifying 10 implant types in Indian clinical settings and compared its accuracy to that of dental professionals. A dataset of 3,161 radiographs, comprising both periapical and panoramic images of 10 implant types, was annotated and used to train and test YOLOv11. Training was performed on Google Colab using an NVIDIA Tesla T4 GPU (16 GB VRAM). A random sample of 200 radiographs was selected from the test dataset and presented to 50 dental practitioners for implant identification. Their responses were analysed and compared, using the chi-square test for statistical significance. YOLOv11 achieved precision of 0.87, recall of 0.85, an F1-score of 0.86, and an mAP50 of 0.899. The model achieved excellent classification accuracy for Adin (95%), MIS (94%), Bego (92%), ITI (96%), and Bicon (97%). Moderate accuracy was noted for Noris (82%), Osstem (85%), AlphaBio (88%), Dentium (77%), and Bioline (75%). YOLOv11 demonstrated higher overall accuracy and consistency than dental professionals. Dentists' accuracy ranged from 27% to 49%, whereas that of YOLOv11 ranged from 92% to 100%. YOLOv11 recognised most implant classes with over 90% accuracy, surpassing traditional manual techniques in implant detection. Although the model is dependable and efficient, certain aspects require improvement. The study also emphasises the significance of a region-specific approach for clinical relevance. The aim of our studdy is clinical evaluation of Platform switch hybrid zygoma implants. 117 zygomatic implants were followed up during this time. They included 55 Brånemark System zygoma implants, 38 Noris implants, and 24 novel iRES hybrid implants with platform switch. Bone quality and quantity are the prerequisite for successful implant treatment. Zygomatic implants are intended for patients with severely resorbed maxilla that cannot accommodate conventional implants without prior extensive bone grafting. Such regenerative procedures, like sinus lifts, prolong implant rehabilitation to several months (12-18). Furthermore, extensive grafts are less predictable showing varying degrees of graft resorption. Zygoma implants enable full, often immediate, reconstruction of the upper dental arch without the need for sinus lift treatment. The original zygoma protocol runs the implants through the sinus, requires general anesthesia, and positions the prosthetic platform of the implants on the palate, which makes prosthesis cumbersome. It also induces risk for post-op sinusitis. Extra-sinus approach with novel zygoma hybrid implants bypasses sinuses and positions the implant prosthetic platform on the crest allowing for same good prosthetics as on conventional dental implants. Furthermore, crestal threads and a platform-switch, of the novel zygoma design, increase implant anchorage and minimize marginal bone loss. The study presents evolution of zygoma implant rehabilitation protocol and zygoma implant design in our clinical practice over 15 years (2004-2019). Extra-sinus zygomatic implant placement lowers the risk of post-op sinusitis and makes procedure possible to be done in local anesthesia. The most common diagnosis for pediatric thrombocytopenia is immune thrombocytopenia. Nevertheless, in atypical cases, the hypothesis of an inherited thrombocytopenia has to be investigated. We report a series of cases of a newly described entity, genetic thrombocytopenia with mutation in the ankyrine 26 gene, diagnosed from the exploration of five pediatric cases of thrombocytopenia. This entity is characterized by a moderate thrombocytopenia with normal mean platelet volume, and poorly bleeding. Its transmission is autosomal dominant. Final diagnosis is made by sequencing of a short DNA region of ANKRD26 gene. This pathology can be considered as an hematological malignancy predisposition syndrome. We report the first cohort of pediatric patients diagnosed with thrombocytopenia with mutation in the ankyrine 26. The aim is to underline the specificities of this entity in children and bring it to the knowledge of pediatricians who may be in first place to manage these patients. • Genetic thrombocytopenia with mutation in the ankyrine 26 gene is a recently described entity, which seems to be considered as a predisposition for hematologic malignancies. • The first cohort has been reported in 2011, by Noris et al., in 78 Italian adult patients. What is New: • We describe clinical and biological features of the first pediatric cohort diagnosed with genetic thrombocytopenia with mutation in the ankyrine 26 gene. • It seemed important to consider the pediatric specificities of this entity to enable pediatricians to investigate, diagnose, and manage pediatric patients and their families. Noris and Remuzzi discuss a new study showing an association between atypical haemolytic uremic syndrome and a hybrid complement gene,CFH/CFHL1. Epidemics of tomato yellow leaf curl have occurred annually in greenhouse- and field-grown tomato (Lycopersicon esculentum Mill.) crops in southern Spain since 1992 (2). The nucleotide sequences of two tomato yellow leaf curl virus (TYLCV) isolates from this region, TYLCV-M (GenBank accession no. Z25751) and TYLCV-Alm (L27708), have been determined and these isolates are closely related to isolates reported from Italy (X61153 and Z28390), suggesting the existence of a geographical cluster of closely related TYLCV isolates in the Western Mediterranean Basin (2

Intense focused ultrasound (IFUS) is a Nonablative skin tightening technology with good safety profile, but limited efficacy. Most clinical studies have been performed to evaluate the efficacy of the Ulthera IFUS (Ulthera, Mesa, AZ) in treating redundant skin. To report our experience with Doublo IFUS (Doublo™, HIRONIC Co.) for treating neck and lower face laxity. This is a prospective study of 43 patients with neck and lower facial laxity treated using IFUS. Response was assessed by two independent dermatologists and graded on a scale of 0 (exacerbation) to 5 (75%-100% improvement). Patient's level of "sagging" and "volume loss", satisfaction and tolerance were documented. Nine subjects (52.9%) mentioned some improvement. Erythema and edema were acute and transient responses. Ultrasound appears to be a safe modality for facial skin tightening in selected patients with minor skin sagging and no volume discrepancy. Intense focused ultrasound (IFUS) is a novel modality for treating skin laxity that produces thermal effects at various depths while sparing the overlying tissue. This study assessed histologic changes and the safety and efficacy of intense focused ultrasound (Doublo(TM), HIRONIC Co., Sungnam, Korea) for tightening of facial skin in Asian patients. Eleven patients with facial laxity were treated with IFUS and evaluated before and after treatment. Mean age was 46 years (range, 35-64 years). Two available hand-pieces with different focal depths (3 mm and 4.5 mm) were used with three to five passes 1-2 mm apart. Outcome assessment included photographic evaluation by two blinded investigators, skin biopsies before and two months after treatment, and patient satisfaction. Subjective and objective analyses showed 63.6% and 72.7% improvement at the two-month evaluation, respectively. Histologic evaluation by hematoxylin and eosin (H&E) and Masson's trichrome staining showed increased collagen fibers in the lower dermis and between fat layers. Intense focused ultrasound can be used as a non-invasive skin tightening technique in Asian patients. It induced collagen generation in the dermis and fat layers and was effective and safe in our study population.

The use of hyaluronic acid (HA) fillers is rising globally. Traditionally, the rheology of HA fillers has been subject to investigations for their use in facial soft tissues. Hitherto, there has been a significant gap in understanding their rheologic properties in body applications. The requirements for body fillers are different from facial fillers as they are applied for larger volume deficits, and experience greater mechanical stress. This study aims to fill this gap by analyzing the physicochemical and rheological properties of HA body fillers to guide clinical practice. Four commercially available HA-based body fillers were analyzed under standardized laboratory conditions. The physicochemical properties, including pH, osmolality, ion concentrations, clarity, and swelling factor, were assessed. Rheological properties, including storage modulus (G'), loss modulus (G″), complex modulus (G*), and tan delta (tan δ), were assessed between 0.1 and 1 Hz. The physicochemical analysis revealed no significant differences among the fillers, indicating uniform chemical stability. However, rheological analysis showed significant variations. Infini B Body exhibited the lowest G', G″, and G* values. In contrast, HYAcorp MLF1 and MLF2 displayed higher G' and G* values, indicating greater elasticity and stiffness. Consistent rankings between 0.1 and 1 Hz suggest stable mechanical performance under dynamic and sustained loading, supporting their suitability for high-load applications such as gluteal augmentation. Selecting HA body fillers based on their rheological properties is crucial for optimizing outcomes, particularly in body contouring procedures where mechanical demands differ from those of facial applications. Clinicians should tailor filler selection to the specific requirements of each body area. Further research is required to validate these findings in long-term clinical settings. This study sought to establish an experimental aneurysm model of visualizing coil insertion using radiolucent nylon coils. Moreover, this study aimed to clarify the characteristics and differences of each coil and use them clinically as indices of coil selection. The coil insertion test was performed on the 10 mm spherical silicone aneurysm model filled to a nylon coil volume embolization ratio of 11.8%. Five types of coil were randomly tested six times, and the distribution of the coils was analyzed by fluoroscopy imaging. Indices of "Area (mm2)," "Feret's diameter (mm)," and "Circularity" were calculated from the fluoroscopic images. Among the indices, only "Area" showed a significant difference between coils (p = 0.002). On multivariate analysis, "Area" of the ED Infini was larger than those of Target XL soft and Galaxy G3 (p = 0.018 and 0.026, respectively). Furthermore, the area of the 360 soft was larger than that of G3 (p = 0.049). Analysis of the correlation between these values and the coil configuration showed that "Area" was negatively correlated with the stock-wire diameter (r = -0.50; p = 0.004) and primary coil configuration (r = -0.65; p < 0.001). When inserting the coils in the early stage, although the difference between each coil is relatively difficult to obtain, knowledge on the proper use of the coils with differences in characteristics can help in selecting the coil most appropriate for the conditions. Introduction Up to 30% of terminally ill cancer patients experiencing intense pain might be refractory to opioid treatment. Complex cancer pain can be a mixture of somatic, visceral, and neuropathic pain with few or no effective alternatives to ameliorate pain. Radiosurgery to treat refractory pain in cancer has been reported with different degrees of success. Radiomodulation in pain could be defined as a fast (<72 h), substantial (>50%) pain relief by focal irradiation to a peripheric, and/or central mediated pain circuitry. Based on our previous experience, mixed, refractory cancer pain is usually unresponsive to single target irradiation of the hypophysis. We treated three patients using a multi-target approach. Methods Three terminally ill oncological patients experiencing refractory, complex, mixed pain from bone, abdomen, thorax, and brachial plexus were treated with triple target irradiation which consisted of irradiating with a maximum dose (Dmax) of 90 Gy to the hypophysis using either an 8 mm collimator with gamma ray (Infini) (Shenzhen, China: Masep Medical Company) or a 7.5 circular collimator with Cyberknife (Sunnyvale, CA: Accuray Inc.), the other two targets were the mesial structures of the thalamus bilaterally using a 4 mm collimator with Infini and the 5 mm circular collimator with CK delivering 90 Gy Dmax to each region. Patients had a VAS of 10 despite the best medical treatment. A correlation was made between the 45 Gy and 20 Gy isodose curves of the two different technologies to the Morel stereotactic atlas of the thalamus and basal ganglia for further understanding of dose distribution reconstructions in accordance with the São Paulo-Würzburg atlas of the Human Brain Project were performed. Lastly, a scoping review of the literature regarding radiosurgery for oncological pain was performed. Results Radiomodulation effect was achieved in all patients; case 1 had a VAS of five at 72 h, three at 15 days, and three at the time of death (21 days after treatment). Case 2 had a VAS of six at 72 h, five at 15 days, and four at the time of death (29 days after treatment). Case 3 had a VAS of five at 72 h, six at 15 days, and six at the time of death (30 days). Morphine rescues for cases 1 and 2 were reduced to 84%, and 70% for case 3. Overall, there were no adverse effects to treatment although excessive sleepiness was reported by one patient. After reading the title and abstract, only 14 studies remained eligible for full-text evaluation, and only nine studies met inclusion criteria after full-text reading. For most reports (seven), the target was the hypophysis and in two reports, the target was the thalamus either with single or bilateral irradiation. Conclusions In complex, for refractory oncological pain of mixed nature (nociceptive, neuropathic, and visceral), very few, if any, treatment alternatives are currently available. We provide a small proof of concept that multitarget intracranial radiosurgery might be effective in ameliorating pain in this population. The doses administered per target are the lowest that have shown effectiveness thus far, a different strategy might be needed as opposed to single target "large" dose approach that has been tried in the past for complex mixed refractory oncological pain. By no means, in our experience, these treatments traduce in elimination of pain, clinical results might make pain to be more bearable and respond better to pain medication. Introduction Meningiomas are extra-axial central nervous system tumors. Complete resection is often curative with macroscopically complete removal of the tumor, excision of its dural attachment, and any abnormal bone. Radiosurgery is also an option for high-risk patients or in patients with surgically residual disease. Dural tail is a typical radiological sign on contrast-enhanced MRI; it can contain tumor cells or be a reaction due to vascular congestion and edema. Radiosurgical planning treatment varies regarding the identification and coverage of the dural tail. This study aimed to retrospectively analyze a series of 143 patients with WHO Grade I meningiomas treated with different radiosurgical platforms, and dosing parameters focused on planning and dose delivery to the dural tail. Methods From February 2011 to July 2020, 143 patients with histologically confirmed or radiologically assumed WHO Grade I meningiomas were treated using rotating gamma-ray Infini™ (Gamma [MASEP Medical Science Technology Develo
