This review discusses the anatomical and histological characteristics of facial fat compartments and reports no new clinical results, emphasizing a need for further research on their role in facial aging.

This case report highlights that a woman experienced arsenic toxicosis from kelp supplements, manifesting as alopecia and memory loss, which resolved after stopping the supplements.

This review explores the mechanisms of hair cell death due to factors like noise, ototoxic drugs, and aging and reports no conclusive clinical results; ongoing research may eventually enable preventive treatments for hearing loss.

This review found that many low-level light therapy studies report beneficial effects but often fail to provide adequate measurement details, affecting the reliability and repeatability of the research.

In this study, four children with recurrent atypical teratoid rhabdoid tumors experienced disease stabilization or regression after treatment with alisertib, suggesting its potential role in future trials for this condition.

This review discusses the biology of hair follicle stem cells and highlights their potential for applications in regenerative medicine, drug, and gene delivery, but reports no new clinical results.

This review describes various types of folliculitis based on their causes, clinical manifestations, and treatments, but reports no new clinical results.

Vitiligo causes white skin patches and is linked to autoimmune issues.

This article reviews the use of finasteride for treating male pattern hair loss, highlighting its mechanism of action in reducing DHT and noting its safety profile with some common adverse effects.
