The results indicate that videodermatoscopy represents a very useful tool in the evaluation of hair loss, both for differential diagnosis (especially in early, transitional and mild forms) and for prognostic evaluation. It allows rapid, detailed, and non-invasive observation of the scalp skin and hair, and it provides high-resolution quality imaging.

Background Dietary habits may play a non‐negligible role in the development, duration, and severity of acne, as shown in past critical review articles on such association. Methods The aim of this systematic review is to supplement data available on scientific literature spanning the last 10 years by inserting the keywords “acne” or “acne vulgaris” and “diet”, “nutrition”, “food”, “chocolate”, “dairy”, “whey protein”, “fatty acid”, or “drink” in the timeframe “January 2009‐April 2020” within the PubMed database. Results Fifty‐three reviewed articles met eligibility criteria. They included 11 interventional clinical trials (seven randomized controlled trials and four uncontrolled open label studies) and 42 observational studies (17 case‐control and 22 cross‐sectional studies, and three descriptive studies). Conclusions This review reinforces the notion of a rapidly growing exponential trend of interest in this subject by the scientific community. Acne‐promoting factors include high GI/GL food, dairy products, fat food, and chocolate, whereas acne‐protective factors include fatty acids, fruit, and vegetable intake. The role played by specific dietary components pertaining to different foods, as done for milk (full‐fat/whole, reduced‐fat, low‐fat/skim milk), dairy products (milk cream, ice cream, yogurt, cheese, etc.), or chocolate (cocoa, dark/milk chocolate), remains an unsolved issue and objective of future research.

We evaluated the efficacy of squaric acid dibutylester (SADBE) contact immunotherapy for the treatment of warts on a series of 188 children. Included in the study were those children who satisfied at least two of the following criteria: single or multiple sites with several warts, warts resistant to repeated medical and/or surgical treatments, recurrent multiple warts, and patient or parent refusal to undergo destructive or surgical treatment. Excluded from the study were children with single warts or with flat warts located exclusively on the face and children less than 2 years of age. Treatment consisted of twice weekly applications of serial dilutions of SADBE (0.03-3%) for no more than 10 weeks. Of the 148 children who completed the study, 124 (84%) showed complete clinical resolution with no significant side effects. Of those with total clinical resolution, 101 completed a 24-month follow-up with no relapses. Twenty-four (16%) children were nonrespondent. No apparent correlation between treatment response and age, gender, anatomic site, lesion type, or atopy was found. Contact immunotherapy with SADBE is a relatively safe and effective alternative treatment in the management of multiple and resistant cutaneous warts in children.

Seborrhoeic dermatitis (SD) is common in Asia. Its prevalence is estimated to be 1-5% in adults. However, larger population-based studies into the epidemiology of SD in Asia are lacking, and the aetiology of SD may differ widely from Western countries and in different parts of Asia. In addition, clinically significant differences between Asian and Caucasian skin have been reported. There is a need to define standardized clinical diagnostic criteria and/or a grading system to help determine appropriate treatments for SD within Asia. With this in mind, experts from India, South Korea, Taiwan, Malaysia, Vietnam, Singapore, Thailand, the Philippines, Indonesia, and Italy convened to define the landscape of SD in Asia at a meeting held in Singapore. The consensus group developed a comprehensive algorithm to aid clinicians to recommend appropriate treatment of SD in both adults and children. In most cases, satisfactory therapeutic results can be accomplished with topical antifungal agents or topical corticosteroids. Non-steroidal anti-inflammatory agents with antifungal properties have been shown to be a viable option for both acute and maintenance therapy.

The purpose of this study is to evaluate the outcome of a series of patients with erythematotelangiectatic rosacea (ETR) affected by persistent erythema and varying degree of telangiectasias being treated with brimonidine alone or combined with a vascular laser based on the type of vascular components preliminarily evaluated by clinical and instrumental observation. Ten patients affected by ETR were enrolled in a pilot, open study. Instrumental evaluation included erythema-directed digital photography by VISIA-CR™ system and X10 dermoscopy. Those patients showing marked background erythema and minimal telangiectasias (group A) were treated with a single application of brimonidine 0.33% gel, while patients showing both marked background erythema and marked telangiectasias (group B) were treated with a session of Nd:YAG laser and reevaluated 1 month later after a single application of brimonidine. An Investigator Global Assessment (IGA) of treatment outcome was performed at the end of treatment in both groups. In group A, 6 h after brimonidine application, a marked reduction of the background erythema was observed in all patients, and IGA was rated as excellent. In group B, 6 h following the application of brimonidine, a marked reduction of the background erythema was observed in all cases, while telangiectasias remained unchanged. A further treatment with brimonidine 1 month after the Nd:YAG laser session determined complete clearing of facial erythema, and IGA was rated as excellent. In conclusion, a preliminary evaluation of the vascular component by erythema-directed digital photography and dermoscopy in ETR may be helpful to select the most appropriate therapeutic strategy.
