This report describes two cases where pemphigus lesions developed at sites of cosmetic procedures, suggesting these treatments might trigger the disease and should be distinguished from other post-surgery complications.

This review outlines the diagnosis and management of folliculitis decalvans, an inflammatory scalp disorder, and highlights Staphylococcus aureus and immune response deficiencies as key factors in its development.

This case report presents a very rare instance of pilonidal sinus in the preauricular region, marking only the second known case documented in medical literature.

In this case study, a 7-year-old boy with kerion celsi experienced persistent inflammation even after microbiological clearance; dermoscopic-guided removal of hair and keratin debris improved his condition, suggesting a novel inflammatory mechanism involving granulomatous response to keratinous debris in tinea capitis.

This review discusses environmental epigenomics and its potential impact on gene regulation and phenotypic outcomes, using the Avy mouse model to illustrate nutritional and environmental effects on the fetal epigenome without presenting new findings.

This study observed that tributyltin pollution induces imposex, reduces reproductive success, and leads to population decline in Ocinebrina aciculata, highlighting its sensitivity compared to other prosobranch species.

This review discusses various adverse drug reactions affecting the skin, hair, and nails, emphasizing the importance of recognizing and reporting these reactions but reports no new clinical findings.

Finasteride effectively blocks rat enzymes, but with varying methods and strength.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

This article discusses treatment approaches for female pattern hair loss and concludes that available medical treatments are effective in reversing or stabilizing the condition in most cases of mild-to-moderate severity.

This study found that the binding of finasteride to the enzyme 5a-reductase occurs at a slower rate than previously assumed, complicating the estimation of its real inhibitory constant.

In this study, enteroendocrine cells were shown to coordinate intestinal stem cell migration towards a wound in Drosophila by releasing a ligand that activates non-canonical Wnt signaling, aiding efficient tissue repair.

This study found that prevascularizing dermal matrices with adipose tissue-derived microvascular fragments improved vascularization and allowed earlier successful skin grafting in a bradythrophic wound model.

This study found that 62% of neutered dogs with hair cycle arrest experienced partial to complete hair re-growth after melatonin treatment, but hair re-growth was not consistently linked to normal sex hormone levels.

This review provides a practical approach to diagnosing pseudopelade of Brocq and updates on treatment options but reports no new clinical results.

This study found that in dogs with alopecia, certain steroid hormone levels were elevated, particularly progesterone, but not all hormone abnormalities were consistent across breeds, suggesting the need for breed-specific evaluation.

This study found that age and follicular miniaturization were extremely weak predictors of total hair count in women with hair loss.

Cosmeceuticals may have potential but their effectiveness and market success are still uncertain.

Finasteride treats enlarged prostate and baldness, but may cause limited urinary improvement and sex-related side effects.

This study found that GI198745 acts as a time-dependent inhibitor of rat 5α-reductase type 2 but a rapid-equilibrium inhibitor of type 1, potentially making it more effective than finasteride in preventing rat prostate growth.

This article reviews the causes and clinical presentation of pseudofolliculitis barbae, highlighting how genetic susceptibility and hair removal practices contribute to its development, but reports no new research findings.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

The exact cause of growth hormone-responsive alopecia in dogs is unclear.

This study found that hair regrowth in Pomeranians with hair cycle arrest treated with melatonin was not associated with a change in oestrogen receptor-α staining.

This study reviews the mechanisms by which SARS-CoV-2 may impact male fertility, noting potential disruptions in spermatogenesis and hormone secretion, and underscores the need for follow-up in recovered men.

This letter details a case report on platelet-rich plasma treatment for a patient with treatment-resistant frontal fibrosing alopecia, but it does not provide new clinical results.

This review outlines various brow-lifting techniques, focusing on the endoscopic brow-lift for its minimal scarring and higher patient acceptance, and reports no new clinical results.

This study suggests that a microemulsion formulation of Minoxidil effectively enhances drug delivery through hair follicles, showing significant follicular response alterations in an alopecia model.

This case report describes a 23-year-old male patient with nail discoloration that may be associated with COVID-19, suggesting possible microvascular damage.

In this study, researchers observed that purpuric, telangiectatic, lichenoid balanitis was the most common histologic pattern in cases of chronic pseudoerythroplastic balanitis, suggesting a possible link to lichen aureus.
