A woman's sudden hair loss was linked to her previous COVID-19 infection.

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 article reviews the thermoregulation mechanisms in African and Asian elephants and highlights challenges from climate change, with no new empirical results presented.

In this study, the varied phenotype of trichothiodystrophy was highlighted, with findings of distinctive hair shaft abnormalities and a wide range of multisystem issues, including neurologic and urologic disorders.

This review provides a comprehensive overview of multidisciplinary dermo-aesthetic interventions for breast cancer patients, aiming to establish safe protocols involving various specialists to improve quality of life, although consultation with an oncologist before treatment is advised.

This study reported that novel adipose slurry injections improved rhytides and dermis density in patients receiving facial wrinkle treatments based on evaluations at multiple follow-up intervals.

This abstract outlines a guide reviewing both FDA-approved and off-label therapies for androgenetic alopecia and proposes treatment algorithms based on scientific research, highlighting a gap in common treatments for this prevalent condition.

This case report discusses a 25-year-old woman diagnosed with acne necrotica varioliformis and highlights the diagnostic challenges and potential associations with systemic diseases.

This study observed that low-dose intrauterine exposure to finasteride alters postnatal prostate development in male and female Mongolian gerbils, showing sex-specific differences in receptor expression and tissue changes.

JAK inhibitors, like baricitinib and ritlecitinib, show promise in treating alopecia areata effectively and safely.

This retrospective cohort study found that both spironolactone and bicalutamide significantly improved Sinclair grade in women with female pattern hair loss over 24 months, but spironolactone, especially at doses above 100 mg/day, resulted in greater efficacy, required less monitoring, and maintained comparable safety.

In this case report, a 45-year-old man with treatment-resistant androgenetic alopecia experienced hair regrowth during oral bicalutamide treatment but also suffered adverse effects leading to discontinuation, highlighting the need for further studies on the safety and role of androgen receptor blockade in hair loss.

This research review observed that topical hormone replacement therapy, particularly estradiol and estradiol-testosterone combinations, significantly increased Type I and III collagen synthesis in the skin of postmenopausal women, suggesting benefits against collagen loss-related skin aging effects such as reduced elasticity and increased dryness.

This study examined three olive oil formulations of baricitinib for topical delivery in treating alopecia areata, finding that Oil A showed the highest skin retention and maintained skin integrity without irritation, suggesting its potential for further investigation.

This study reports that treating a feline with progressive pruritus, alopecia, and FIV infection with imidacloprid and moxidectin resulted in remission of clinical signs and elimination of Demodex cati mites, as confirmed by parasitological examination and genetic sequencing.

This study examined the clinicopathological characteristics of cutaneous squamous cell carcinoma on the scalp and ear but reported no new results on its association with androgenetic alopecia.

Severe alopecia areata may increase the risk of hidden artery disease.

This study found that using human induced pluripotent stem cells (iPSC) carrying the causal mutation of Epidermolysis Bullosa simplex provides a robust model for understanding its molecular mechanisms and testing potential therapeutic targets.

This article reviews the influence of vitamin D on various dermatological diseases and suggests that vitamin D supplementation might aid in maintaining skin cell homeostasis; it reports no new clinical results.

Hair restoration techniques have improved significantly.

In this study, a combined treatment of Androcur and Diane improved acne, seborrhea, hirsutism, and androgenic alopecia in women to varying degrees over two years.

This review discusses the molecular role of the vitamin D receptor in regulating various biological actions such as bone mineralization and reports no new clinical results, highlighting the complexity of vitamin D's function in multiple tissues.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This review discusses the emerging "endocrine phenotype" of COVID-19, highlighting the implications for managing diabetes, obesity, vitamin D deficiency, and other endocrine conditions in affected patients.

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 study from Los Angeles supports the idea that using permanent hair dye may increase bladder cancer risk in US women, especially those with a slow NAT2 acetylation phenotype.

This study found that transgenic mice expressing a mutant CYLD protein lacking deubiquitinase function showed signs of premature aging and spontaneous tumor development, likely due to over-activation of specific molecular pathways and chronic inflammation.

This study explores how SARS-CoV-2 interacts with endocrine organs and highlights specific endocrine molecules that help explain the progression and outcomes of COVID-19, especially in patients with certain metabolic conditions.

Nanocarriers could improve how drugs are delivered through the skin but require more research to overcome challenges and ensure safety.

This study reported that about one-third of post-COVID-19 patients experienced long-term symptoms, with women, older individuals, smokers, and those with specific blood groups at higher risk for complications.
