This study found that in healthy men, higher levels of free testosterone were associated with a stronger immune response to the influenza vaccine, suggesting androgens may function as immunomodulators rather than strict immunosuppressants.

This review argues that the immunocompetence hypothesis, linking masculine facial features to attractiveness through health benefits, lacks sufficient evidence and sidesteps alternative explanations.

The authors describe drug repurposing as a promising strategy for finding new uses for existing drugs, noting it is efficient, cost-effective, and poses lower risks than traditional drug discovery processes, potentially aiding in the treatment of rare and difficult-to-treat diseases.

This case report highlights two instances of suspected human herpesvirus 6 reactivation in patients with existing psychiatric disorders, underscoring the need for further research into the relationship between viral reactivation and psychiatric conditions.

In this review, researchers reported that pyroptosis, a type of inflammatory cell death linked to inflammasome activity, is a key factor in the pathogenesis of alopecia areata and may present new therapeutic opportunities, though most treatments are still in early research stages.

In this study, demodicoses were found to be relatively common among immunocompetent patients, with a notable overlap with papulopustular rosacea.

This study demonstrated that gene-corrected 3D skin constructs from RDEB patient-derived iPSCs, grafted onto immunocompetent mice, showed normal collagen VII expression after two months.

This article discusses a novel hypothesis on the role of hair follicles in dandruff pathogenesis, focusing on immune response and inflammation due to scalp microbiota changes and sebum by-products, but reports no new clinical results.

The study reported that Demodex musculi infestation was notably higher in immunodeficient mice, while infested immunocompetent mice, particularly the BALB/c strain, showed increased IgE levels and developed alopecia over time.

This study observed that in varicella, the varicella-zoster virus spreads to dermal endothelial cells before reaching keratinocytes, whereas in herpes zoster, it first involves cutaneous nerves and pilosebaceous units.

This study found that hair follicles may provide a safe space for tumor cells in mice, suggesting a potential target for cancer prevention during the dormant phase of tumor development.

This study observed that reduced activation of SMAD2/3 proteins in cutaneous squamous cell carcinoma tissue compared to adjacent tissue may indicate a tumor suppressor role in disease progression.

This review summarizes current evidence on how beta-human papillomavirus and Merkel cell polyomavirus may contribute to the development of nonmelanoma and Merkel cell skin carcinomas, respectively, but it reports no new clinical findings.

This study found that while men's facial appearance, specifically attractiveness and masculinity, correlated with cardiometabolic indicators like insulin resistance and triglycerides, these links disappeared after adjusting for factors such as age, adiposity, and testosterone levels, suggesting that facial cues do not reliably indicate metabolic health.

This study suggests that finasteride treatment may improve pulmonary immune response in mice following trauma and sepsis, indicating potential as a therapeutic option after major trauma.

This study found that increasing commensal bacterial load on the skin enhances wound-induced hair follicle neogenesis in mice, mediated through IL1R-MyD88 signaling pathways.

In this study, most hair disorders among HIV-1 positive patients were associated with low helper T cell counts, with papulosquamous conditions like seborrheic dermatitis and psoriasis being the most common.

This study found that short-chain fatty acids produced by the skin microbe Propionibacterium acnes may drive inflammatory gene expression in sebocytes, potentially contributing to acne.

This study suggests that human and mouse hair follicle stem cells may support nerve repair and provide a practical source of stem cells for neurological therapies.

This study found that arctiin, a compound from Arctium lappa, demonstrated protective effects against oxidative stress-induced dysfunction in human hair dermal papilla cells, suggesting potential therapeutic use for alopecia.

In this letter, thrombocytosis was associated with the use of low-molecular-weight heparin in a patient with adrenal cortical carcinoma, highlighting a potential side effect of this treatment.

This article reports the first case of group B streptococcal meningitis in an HIV-positive patient who had previously undergone a splenectomy.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

This report documented a case of thrombocytopenia and leukopenia linked to the long-term use of itraconazole in a patient with acute myelogenous leukemia.

This article discusses a report on reversible alopecia associated with fluconazole therapy and mentions other possible causes of hair loss but presents no new findings.

This review discusses the roles of hair follicles and sebaceous glands in percutaneous transport and reports no new results, noting a lack of adequate models and methodologies.

This review summarizes current evidence on the use of contact immunotherapy, excluding alopecia areata, for various skin diseases, discussing its safety, efficacy, and the underlying mechanisms as reported from studies in the PubMed database.

Transplant patients often get skin problems, with treatments varying by condition.

This correspondence reported significant variability between quantitative PCR and bDNA assays for measuring Hepatitis C virus RNA in high-titer specimens, challenging the reliability of the Chiron assay.

In 1995, international medical graduates did better than U.S. graduates on a medical exam.
