This report describes four trichoblastoma cases rich in Merkel cells, suggesting these tumors may mimic fetal skin development where Merkel cells are numerous.

This study reported significant short-term scalp hair regrowth and increased density in a 4-year-old with Marie Unna hereditary hypotrichosis following topical 5% minoxidil treatment, suggesting its potential benefit in this condition.

This study suggests that Rushton’s hyaline bodies form through both epithelial changes leading to hair keratin production and hemorrhage supplying erythrocytic substances, resolving previous debates about their origin.

This study found that human adipose tissue-derived mesenchymal stem cells inhibited A549 tumor growth but significantly promoted HT-29 tumor growth in mouse models, highlighting opposing effects depending on the cancer type.

This study found a previously unreported ST14 gene mutation in a patient with ichthyosis-hypotrichosis syndrome, highlighting novel skin and hair characteristics and emphasizing the critical role of the Asp482 amino acid in matriptase activation.

This study found that minoxidil stimulates the Kir6.2/SUR2 potassium channel, leading to tumor growth arrest in an ovarian cancer xenograft model by disrupting mitochondrial function and inducing cell death.

This case report describes a man diagnosed with Hoffman syndrome, characterized by muscle hypertrophy and weakness due to severe hypothyroidism, who had an excellent response to thyroid hormone replacement.

This study found that high stress levels among medical students were significantly associated with their performance in the UKMPPD certification exam, with academic stressors being the primary contributors.

In this study, 2.5% mineral-rich spring water showed a potential hair growth-promoting effect in SKH-1 hairless mice, suggesting it may be a novel approach for managing hair loss.

This review discusses Limbal Mesenchymal Stem Cell Secretome therapy for ocular chemical injuries, noting its potential in reducing inflammation and corneal opacity, but reports no new clinical results.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

This review presents a comprehensive evaluation of medical reasoning using large language models, highlighting a significant gap between exam-level performance and true clinical decision-making accuracy.

This study demonstrated that keratin K124 is specific to equine hoof lamellar tissue and established monoclonal antibodies that can specifically recognize K124 without cross-reacting with other tissues.

This study found that 70-MHz ultrasound can detect early signs of hidradenitis suppurativa linked to severity, including hair follicle abnormalities and keratin fragmentation, aiding in diagnosis and management.

This study observed that male pattern hair loss patients are getting diagnosed earlier and presenting with milder forms, possibly due to early puberty, and noted frequent familial predisposition and comorbidities like seborrheic dermatitis.

This case report describes a successful treatment of sarcoidal foreign body reactions caused by permanent makeup ink with local steroid injections, while also identifying the involvement of M2 macrophages in the reaction.

This study suggests that expanding the Egyptian premarital screening program to include dermatological conditions, sexually transmitted diseases, and andrological disorders could enhance marriage stability.

In this case study, an 8-day-old neonate with holocarboxylase synthetase deficiency showed dramatic improvement in lactic acidosis and overall clinical condition following biotin mega-dose therapy, highlighting the importance of early genetic testing and timely treatment in such metabolic disorders.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This study found that Minoxidil had biphasic effects on normal human keratinocytes, stimulating proliferation at micromolar doses, but showing antiproliferative, pro-differentiative, and cytotoxic effects at millimolar concentrations.

This review discusses identifying keratosis pilaris, its common mimics, and its associated skin diseases across different skin tones but reports no new results.

This paper explores the relationship between the dermal extracellular matrix and cutaneous malignant melanoma, suggesting that ECM involvement may play a key role in the cancer's growth, invasiveness, and initial metastasis.

This study found that SHJ extract increased hair growth and melanogenesis in mice, suggesting potential use in cosmeceuticals for hair care.

This study found that KF19418 stimulated hair follicle growth in vitro and accelerated hair regrowth in a mouse alopecia model, with effects comparable to minoxidil.

This study found that in a sample of girls and adolescents aged 15–24 years, the prevalence of PCOS was 22.5% according to the Rotterdam criteria.

This study found that human TMEM2 does not function as a hyaluronidase but is involved in regulating hyaluronan metabolism.

Mutations in the DSG4 gene cause specific hair and scalp issues.

This study found that multimodal recruitment strategies successfully achieved target recruitment quickly and created a racially diverse cohort to study ovulation and menstruation health, with higher survey completion rates noted among participants recruited via the internet and community fairs than in clinics.
