Analysis of the content of YouTube videos discussing acne, psoriasis, and anti-aging skincare in Arabic.

An increasing number of patients turn to YouTube for medical information, driving the growth of research on medical video content, including in dermatology. The objective was to analyze the content of YouTube videos discussing acne, psoriasis, or anti-aging skincare in Arabic. This infodemiological study analyzed the most viewed videos on these topics.

Umbilical seborrheic keratosis-like lesion developing after diode laser hair removal in an 18-year-old patient.

Objective: to report a possibly novel complication of laser hair removal.

Case Report: a white-skinned 18-year-old patient discovered an umbilical, brown, and raised lesion while shaving before his second diode laser hair removal session. He sought consultation before his fourth laser session since the lesion further thickened and darkened.

Beneficial UVB phototherapy preceding a fractional CO laser-UVB protocol in refractory non-segmental vitiligo.

Objectives: To explore the short- and long-term effects of UVB phototherapy preceding a fractional CO laser-UVB protocol in patients with resistant nonsegmental vitiligo.

Materials And Methods: This single-center, prospective, split-face/body, evaluator-blinded study included adult patients with stable vitiligo refractory to conventional treatments. Two symmetrical lesions were selected.

Clinical and pathological features associated with high-risk, multiple, and recurrent basal cell carcinomas: a retrospective cohort analysis from the Levantine coast of the Mediterranean Sea.

Basal cell carcinoma (BCC) data coming from the Levantine coast of the Mediterranean Sea are limited. The study aimed to primarily analyze the demographic, clinical, pathological, and prognostic characteristics of BCC in this region of the world and secondarily identify features associated with high-risk, recurrent, or multiple BCCs. Patients with at least one diagnosis of BCC registered in the pathology department between January 2015 and December 2019 were included in this analytical retrospective single-center cohort study.

Big toenail onychomycosis features associated with response to 1064 nm Nd: YAG laser treatment.

Background: A few studies discussed the factors correlated to response in laser treatment of onychomycosis.

Objective: This study aimed to seek big toenail onychomycosis features that correlate with response to 1064 nm Nd: YAG laser treatment.

Methods: This single-center, retrospective study included patients who had only one big toenail onychomycosis, with a confirmed mycological diagnosis and/or a high clinical suspicion.

The Multifaceted Engagement of the Dermatologist in the Covid-19 Pandemic.

Dermatologists worldwide are engaged in the struggle against Covid-19. They limited their daily activity to priority cases, intending to reduce the exposure of patients in the waiting room. Teledermatology was recommended as an efficient alternative to assure patients' needs and safety.

Searching predictive factors of efficacy and safety in a fractional CO laser.

A few studies discussed short outcomes in fractional CO laser. This study aimed to seek factors of medium-term efficacy and safety in patients treated for facial rejuvenation or acne scars. This single-center, prospective, single-arm, evaluator-blinded cohort study included patients of 18 years and older undergoing a fractional CO laser for facial skin rejuvenation or atrophic acne scars.

Sickle cell disease induces resistance to cutaneous carcinogenesis.

Background: While skin carcinomas are reported in chronic ulcers and in patients treated with hydroxyurea (HU) for myeloproliferative neoplasms, no skin carcinoma has been reported in patients with sickle cell disease (SCD), presenting chronic skin ulcers or treated with HU. The objective was to estimate the risk of cutaneous malignant transformation in SCD patients with prolonged leg ulcers or under HU therapy.

Results: In this cross-sectional study, the cohort consisted of 1543 patients.

Triggers, clinical manifestations, and management of pediatric erythema multiforme: A systematic review.

Background: Erythema multiforme (EM) is an acute inflammatory mucocutaneous condition. EM is rarely described in children and infants.

Objective: To investigate the triggers, clinical manifestations, and treatment of pediatric EM.

[Skin and pregnancy].

Skin and pregnancy. Skin manifestations during pregnancy are common and diversified. Physiological changes are the most frequently reported.

Skin disease in pregnancy.

Skin manifestations during pregnancy are common and diversified. This review will focus on the most important entities to be recognized by obstetricians. These are, on the one hand, physiological changes, where unnecessary investigations should be avoided, and on the other, the specific dermatoses of pregnancy.

[Pregnancy-specific dermatoses].

Pregnancy-specific dermatoses include polymorphic eruption of pregnancy, atopic eczema of pregnancy, and pemphigoid gestationis. Intrahepatic cholestasis of pregnancy and impetigo herpetiformis are not real pregnancy-specific dermatoses but they are important to know considering the fetal and maternal risks. Polymorphic eruption of pregnancy is a pruritic disease that usually occurs in primiparous women during the last trimester of pregnancy.

Reversibility of hyperhidrosis post axillary depilatory laser.

Hyperhidrosis and bromhidrosis were lately reported as novel side effects of laser-assisted removal of axillary hair. The goal of our study was to evaluate the reversibility of these two side effects. An observational, single-center cohort study included over a 30-month screening period 30 patients with newly reported hyperhidrosis and/or bromhidrosis related to axillary depilatory laser.

Low blood concentration of hydroxychloroquine in patients with refractory cutaneous lupus erythematosus: a French multicenter prospective study.

Objective: To study the relation between blood concentration of hydroxychloroquine and the clinical efficacy of hydroxychloroquine sulfate in a series of patients with cutaneous lupus erythematosus (CLE).

Design: Prospective multicenter study. A staff dermatologist blinded to blood hydroxychloroquine concentrations performed a standardized review of medical records and assessment of hydroxychloroquine efficacy in the following 3 categories: complete remission, partial remission (clearing of >50% of skin lesions), or treatment failure.

Nodular lesions of self-healing juvenile cutaneous mucinosis: a pitfall!

Self-healing juvenile cutaneous mucinosis (SHJCM) is a rare disorder of unknown origin, which occurs in children in good health. It is characterized by the multiplication of transient cutaneous papules and nodules, mainly located on the head and periarticular areas that spontaneously resolve. Histological features of SHJCM have been well described; therefore, the diagnosis is usually made easily when papules are biopsied.

[Neutrophilic dermatoses].

Neutrophilic dermatoses are inflammatory disorders where normal neutrophils infiltrate the skin without infection. Sweet's syndrome, pyoderma gangrenosum, subcorneal pustulosis, erythema elevatum diutinum and a few other conditions are included in the spectrum of neutrophilic dermatoses. In addition to their typical presentation, atypical and overlap forms of these disorders may be observed.
