Porokeratosis is a group of chronic dermatoses characterized by the presence of cornoid lamellae. Disseminated superficial actinic porokeratosis (DSAP) is a common subtype, presenting as multiple small annular scaly lesions primarily in sun-exposed areas. While previous studies have documented DSAP in prostate cancer patients, the association with androgen deprivation therapy (ADT) has not been reported. In this report, we describe an elderly patient with advanced prostate cancer, who developed DSAP subsequent to undergoing ADT. We present the clinical, dermoscopic, and histopathological evaluations, and discuss the potential role of ADT in the pathogenesis of DSAP.

Background: An increased frequency of hand sanitizer use and washing hands with soap seems to increase the incidence of hand eczema (HE). Objectives: The aim was to analyze HE in nonmedical personnel, its severity, and the effect of hand sanitizer use on transepidermal water loss (TEWL) and skin capacitance. Methods: This observational cross-sectional study was conducted from July to September 2022. Subjects were recruited based on the study criteria with cluster random sampling method. Each subject's identity, data related to hand sanitizer use and handwashing, atopic stigmata, and duration of HE were documented. The severity of HE was assessed with the HE Severity Index (HECSI). TEWL and skin capacitance were measured with the Tewameter® TM 300 and Corneometer® CM 825 instruments. Results: Out of 240 subjects who were selected randomly, 24 normal subjects and 24 subjects with HE were recruited. The incidence of HE in nonmedical personnel using hand sanitizer was 10%, with a median disease duration of 22 weeks and a mean HECSI score of 9.25 ± 6.33. There was no significant difference in TEWL and skin capacitance between the groups (P > 0.05). There was no significant correlation between TEWL and skin capacitance with the HECSI score (P > 0.05). Subjects with HE washed their hands more frequently than subjects without HE (6 vs. 4.5 times per day; P 0.005). Conclusion: Most nonmedical personnel with HE had a mild form of the condition. There were no significant barrier function and skin hydration differences between the groups.

Research has begun to illustrate a favorable efficacy and side-effect profile for many systemic agents used in pediatric dermatological conditions (i.e. atopic dermatitis, psoriasis, scleroderma, alopecia areata, chronic spontaneous urticaria, autoimmune blistering disorders, and hidradenitis suppurativa) despite not having extensive randomized clinical trials. The purpose of this article is to summarize the available data on the treatment regiments, safety, and efficacy of systemic immunosuppressants, including the newer biologics, focusing on the most up-to-date systematic reviews or randomized clinical trials. The review demonstrates that many of the present studies lack data on long-term efficacy and consist of small patient populations. Further research into the long-term safety of these systemic medications is of vital importance especially due to the chronic nature of most pediatric dermatological conditions that require the use of systemic agents.

Diagnostic procedures in pediatric dermatology are different and significantly more challenging than those in adult patients, especially on how to approach the patients. We need to acknowledge that pediatric patients have unique anatomical, physiological, and psychological aspects. Compared to adults, children have smaller procedure area, are less cooperative, and more difficult to understand. For these reasons, we should perform diagnostic procedures on children cautiously. Having extensive knowledge in this field can facilitate us to carry out an ethical, efficient, targeted procedure with less risk. This article reviewed the most appropriate, most comfortable, and least invasive diagnostic procedures for children. Some of the most commonly performed pediatric dermatology procedures highlighted in this article are potassium hydroxide examination, Gram staining examination, acid fast bacilli examination, skin test for allergies, and skin biopsy for children. We also discuss the process of obtaining a written informed consent from the parents who were involved in decision making process and play a crucial role in assisting physicians to calm their children during the diagnostic procedures.
