In this case report from People's College of Medical Sciences, a 20-year-old man initially misdiagnosed with Addison's disease was ultimately found to have strongyloidiasis, with his symptoms and weight loss improving after antihelminthic treatment.

This review explores the role of transient receptor potential vanilloid channels in the pathogenesis of osteoarthritis but reports no new clinical results.

This study found that systemic ovalbumin–aluminum sensitization followed by cutaneous challenge in mice induced thermal hyperalgesia, increased spinal cord gliosis, and sprouting of nociceptive fibers, along with elevated mast cell and nerve profile densities in the skin compared to controls.

This review discusses various microneedle technologies for long-acting drug delivery, highlighting design considerations and challenges in bringing these minimally invasive devices to market, but it reports no new clinical results.

This study observed that multimodal therapy, including platelet-rich plasma, minoxidil, finasteride, and lifestyle modifications, significantly improved hair diameter and density among individuals with androgenetic alopecia and other noncicatricial hair loss conditions, especially in less advanced cases, after at least 8 sessions.

This research highlights that engineered mice lacking the vitamin D receptor show multiple health issues similar to human vitamin D deficiency, underscoring the widespread impacts of the vitamin D endocrine system.

This review explores the diverse physiological roles of the vitamin D endocrine system, discussing current research on receptor structure, transcription details, murine models, and alternative receptors, but reports no new findings.

This study identified new dietary ligands for the human vitamin D receptor, including curcumin and gamma-tocotrienol, which may influence its biological functions.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

This article compares two rare genetic diseases, vitamin D-dependent rickets type 1 and type 2, focusing on their similar presentations of hypocalcemia and rickets in infancy, but reports no new clinical results.

This study found that mice lacking the vitamin D receptor (VDR) developed skin tumors more rapidly than those with normal VDR activity, regardless of 1,25-dihydroxyvitamin D(3) presence.

This review explores the impact of vitamin D deficiency on the skin from a dermatological perspective, but reports no new clinical results.

This study observed that the vitamin D receptor is crucial for hair follicle formation and altering tumor development in the Wnt signaling pathway, suggesting therapeutic potential for vitamin D analogues in related tumors.

This review examines the impact of vitamin D signaling in extraskeletal tissues and notes that expected benefits from animal and cell studies have not been consistently replicated in human clinical trials.

This abstract reviews hereditary vitamin D-resistant rickets, a rare genetic condition causing severe early childhood rickets, and reports no new results; effective treatment typically requires high doses of calcium to address hypocalcemia and secondary hyperparathyroidism.

Lack of vitamin D receptor increases skin tumor risk by boosting hedgehog signaling.

This article outlines the potential for upregulating the vitamin D receptor in treating hair disorders, emphasizing the need for further studies to evaluate vitamin D's role in the hair cycle.

This study found that measuring 24-OHase induction by 1,25(OH)2D3 in cultured skin fibroblasts is a sensitive test for detecting genetic defects in the 1,25(OH)2D effector pathway.

This study found that Hairless (Hr) acts as a corepressor of the vitamin D receptor (VDR) in human keratinocytes, blocking the action of vitamin D on keratinocyte differentiation.

Vitamin D3 affects cell differentiation in specific skin areas.

This study found that AR/VDR-targeted agonist hormone therapy can inhibit cell viability in HR2-av triple-negative breast cancer cell lines through multiple mechanisms and may enhance the effects of chemotherapy.

This study suggests that vitamin D and its receptor may protect against the development of epidermal tumors following UV radiation by regulating specific cellular signaling pathways.

This article reviews the role of vitamin D receptor in protecting the skin from UV radiation-induced damage and tumor formation, but it reports no new clinical results.

This review discusses the various roles of vitamin D in skin disorders, including established use in psoriasis and potential applications for atopic dermatitis and skin cancer prevention, but reports no new clinical results.

This study found no protective effect of topical calcipotriol on hair loss in chemotherapy patients, and the authors propose the term "atrophic telogen effluvium" for this type of hair loss.

In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This review discusses the multifaceted role of vitamin D in the body, noting its influence on calcium balance, hair cycle maintenance, cell proliferation, cardiovascular function, and immune modulation, with no new clinical results reported.

This study found that in a mouse model with hereditary 1,25-dihydroxyvitamin D resistant rickets, a mutant vitamin D receptor lacking hormone-binding ability could restore normal hair cycling and affect parathyroid hormone regulation.
