Intralesional corticosteroid therapy (ICT) is a recommended management strategy for various inflammatory hair loss disorders. Pain from ICT can limit the use of this treatment, particularly in younger people and those with needle phobia. We present data demonstrating that vibration assisted analgesia, is a safe, effective and easy to use technique, which minimises pain from ICT, allowing its use in a wider cohort of patients.

BACKGROUND
The benefit of Glucagon-like Peptide-1 (GLP-1) receptor agonists (RAs) in weight reduction against potential harms remains unclear. This study aimed at evaluating the benefit-harm balance of initiating GLP-1 RAs versus placebo for weight loss in people living with overweight and obesity but without diabetes.
METHODS
We performed benefit-harm balance modelling, which will be updated as new evidence emerges. We searched for randomised controlled trials (RCTs) in PubMed, controlled trials registry, drug approval and regulatory documents, and outcome preference weights as of April 10, 2024. We synthesize data using pairwise meta-analysis to estimate the effect of GLP-1 RAs to inform the benefit-harm balance modelling. We predicted the absolute effects of the positive and negative outcomes over 1 and 2 years of treatment using exponential models. We applied preference weights to the outcomes, ranging from 0 for least concerning to 1.0 for most concerning. We then calculated whether the benefit of achieving 5% and 10% weight loss outweighed the harms on a common scale. The analyses accounted for the statistical uncertainties of treatment effects, preference weights, and outcome risks.
FINDINGS
We included 8 RCTs involving 8847 participants. The pooled average age was 46.7 years, with the majority being women (74%) and people living with obesity (96%). Of 1000 persons treated with GLP-1 RAs for 2 years, 375 (95% confidence interval 352 to 399) achieved a 10% weight loss, and 318 (296 to 339) achieved a 5% weight loss compared to those treated with placebo. Several harm outcomes were more frequent in the GLP-1 RA group, including 41 abdominal pain events per 1000 persons over 2 years (19 to 69), cholelithiasis (8, 1 to 21), constipation (118, 78 to 164), diarrhoea (100, 42 to 173), alopecia (57, 10 to 176), hypoglycaemia (17, 1 to 68), injection site reactions (4, -3 to 19), and vomiting (110, 80 to 145) among others. Achieving a 10% weight loss with GLP-1 RA therapy outweighed the cumulative harms, with a net benefit probability of 0.97 at year 1 and 0.91 at year 2. The absolute net benefit was equivalent to 104 (100 to 112) per 1000 persons achieving a 10% weight loss over 2 years without experiencing any worrisome harm. A 5% weight loss did not show a net benefit, with probabilities of 0.13 and 0.01 at year 1 and year 2, respectively. However, these benefits were sensitive to preference weights, suggesting that even a 5% weight loss could be net beneficial for individuals with less concern about harm outcomes. The net benefit for a 10% weight loss was highest for semaglutide, followed by liraglutide and tirzepatide, with 2-year probabilities of 0.96, 0.72, and 0.60, respectively.
INTERPRETATION
The benefit of GLP-1 RAs exceeded the harms for weight loss in the first 2 years of treatment, yet the net benefit was dependent on individual' treatment goals (10% or 5% weight loss) and willingness to accept harms in pursuit of weight loss. This implies that treatment decisions have to be personalized to individuals to optimize benefits and reduce harms and overuse of treatments. Due to varying evidence, especially regarding harm outcomes across studies, it is necessary to continuously update and monitor the benefit-harm balance of GLP-1 RAs.

Telogen effluvium is characterized by excessive hair shedding usually following a stressful event. Ferritin has been used in clinical practice as a biomarker of nonanemic iron deficiency in cases of telogen effluvium. During the years of the COVID19 pandemic, telogen effluvium was reported as a part of post covid manifestations. As ferritin was also a biomarker for inflammation in cases with covid infection, this study was designed to evaluate the value of ferritin in cases with postcovid telogen effluvium one hundred patients recovering from covid 19 for 4-12 weeks were included in the study, detailed drug and laboratory history was obtained and serum ferritin level was measured. the mean serum level of ferritin among telogen effluvium patients was significantly lower than controls (68.52 ± 126 and 137 ± 137.597 ug/L respectively). Patients with telogen effluvium used significantly more azithromycin and ivermectin and significantly less vitamin C, D, lactoferrin and zinc than the controls Although serum ferritin is lower among telogen effluvium patients, it was still higher than the cutoff value for diagnosing nonanemic iron deficiency, we suggest that it will not be a good biomarkers in these cases. Our secondary outcomes showed that dietary supplements used during active infection such as vitamin C, D, lactoferrin and zinc might have a preventive value on postcovid hair loss, while azithromycin and ivermectin could have a negative long term effect on telogen effluvium.

Review
Gluten, a polypeptide hapten, found in many cereals such as barley, wheat, rye, oats, and others, has been recently implicated in a range of cutaneous disorders ranging from chronic plaque psoriasis through psoriatic arthritis, urticaria (chronic as well as paediatric onset), and angioedema to lichen planus, vitiligo, and rosacea. The evidence for them is still not well reviewed. To generate evidence for the causal role of gluten in various dermatological disorders. The Pubmed, MedLine, and EMBASE databases were searched using the keywords "Gluten" and one of the dermatoses, namely, "Atopic Dermatitis", "Vasculitis", "Psoriasis", "Psoriatic Arthritis", "Acne", "Alopecia Areata", and "Immunobullous disorders". All articles published in English for which free full text was available were taken into consideration. The search strategy returned in a total of 1487 articles which were screened for relevance and elimination of duplicates. Ultimately, around 114 articles were deemed suitable. The data were extracted and presented in the narrative review format. A simple and cost-effective solution to many of these chronic and lifelong conditions is to restrict gluten in the diet. However, the dermatologist would do well to remember that in the vast majority of dermatological disorders including the ones listed here, gluten restriction is not warranted and can even lead to nutritional deficiencies. The evidence varied from Grade I for some disorders like psoriatic arthritis to Grade IV to most disorders like acne, vitiligo, vasculitis, and atopic dermatitis. Herein, we review the evidence for each of these conditions and make practical recommendations for gluten restriction in them.

BACKGROUND
Telogen effluvium (TE) is the most common cause of alopecia in women. Treatment should address the etiological factors and may include adjuvant therapies. In practice, physicians may employ modified approaches and utilize various combinations of topical and oral molecules.
AIMS
In this real-life observational study, the aim was to evaluate the response of TE to iron supplementation.
MATERIALS AND METHODS
The population consisted of all patients who sought consultation for TE at our dermatology department between March 2021 and February 2022. Eligible participants were women, aged between 18 and 65, having a clinical diagnosis of TE, and intended for treatment with iron supplementation. Exclusion criteria comprised current pregnancy, chronic or active inflammatory disease, newly discovered dysthyroidism, concurrent use of hair supplements, topical minoxidil, or any other medications. The response was assessed based on the patient's level of satisfaction, a significant indicator, given the substantial psychological impact of TE on women's daily lives.
RESULTS
The analysis included 200 women. The average age was 32.9 ± 11.4 years. A recent history of COVID-19 or treated dysthyroidism was present in 18.5% and 8% of patients, respectively, but did not impact their response. Significantly, patients with baseline ferritin ≥50 ng/ml were mostly "very satisfied", those with baseline ferritin <50 ng/ml were mostly "not satisfied", and those with unknown levels were mostly "partially satisfied" with iron supplementation. A high dose of elemental iron and a prolonged duration of treatment significantly improved the patients' level of satisfaction.
CONCLUSION
Iron supplementation can improve the patient's level of satisfaction in TE even if serum ferritin is not low.

In recent years, with the increased usage of tumour necrosis factor (TNF) inhibitors, more side effects have been revealed. Paradoxical psoriasis, including psoriasis vulgaris, palmoplantar pustulosis, scalp psoriasis and their combinations, is a common adverse effect. However, erythrodermic psoriasis associated with alopecia due to anti-TNF-α is rarely reported in the literature. We report a 44-year-old woman who developed erythrodermic psoriasis associated with diffuse alopecia during her treatment with adalimumab for palmoplantar pustulosis.

Review
Patterned hair loss (PHL) is a severe hair condition that affects both sexes. Mesotherapy is a treatment that involves microinjecting medications and/or vitamins into the middle layer of the skin. Mesotherapy reduces systemic adverse effects by delivering drugs directly to the hair follicle, increasing local bioavailability while lowering systemic exposure. Local side effects and reactions may develop due to mesotherapy. This study systematically evaluated the safety and efficacy of mesotherapy to minoxidil 5%, as well as addressing its limitations, dosing, and technique, with the intent of providing valuable trials and insights for clinicians and patients considering mesotherapy for improved androgenetic alopecia (AGA) outcomes. The literature search carried out by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria yielded 11 relevant studies from an initial pool of 18 articles. These studies covered various aspects of the role of mesotherapy and minoxidil in AGA, including techniques, complications, limitations, and outcomes. In conclusion, available trials and research on mesotherapy and minoxidil demonstrated excellent statistical significance and a high patient satisfaction rate, with the exception of two publications that took into account certain uncommon adverse effects of mesotherapy. However, recent research suggests that a mesotherapy method for alopecia with a low risk of side effects is effective.
