This article discusses nutritional contributions to hair health and highlights the need for identifying risk factors for deficiencies but reports no new clinical findings.

This study describes a case of vitamin D resistant rickets in a young girl due to end organ unresponsiveness, highlighting a possible new subtype of the disorder with distinct clinical features.

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

This review addresses clinical findings in parathyroid disease and discusses the metabolism of calcium, phosphorus, vitamin D, and parathyroid hormone, reporting no new results.

The conclusion is that different blood diseases cause specific oral symptoms and require varied treatments to manage these symptoms and improve patient health.

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 examines non-invasive methods for diagnosing inflammatory skin diseases like lupus erythematosus and psoriatic inflammation using samples from plucked hair and skin tape-strips, but no new clinical results are presented.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

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.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This study found that selective deletion of Ctip2 in epidermal keratinocytes in adult mice leads to atopic dermatitis-like inflammation and suggests Ctip2 plays a crucial role in skin barrier maintenance and inflammatory regulation.

This study provides evidence-based recommendations for the off-label use of topical vitamin D in treating certain skin conditions, but highlights the need for higher quality studies for further validation.

In this study, researchers analyzed spaceflight data from various sources and found that skin issues during spaceflight are linked to DNA damage, mitochondrial dysregulation, and gene alterations, while also highlighting the skin's adaptability post-flight.

This case study highlights the complexity of managing autoimmune polyglandular syndrome type 1, emphasizing the need for thorough clinical history, high suspicion for early diagnosis, and continuous long-term follow-up.

In this retrospective study of eight Saudi children with hereditary vitamin D resistant rickets, researchers observed that adjunctive cinacalcet appeared safe and showed initial promise in improving serum PTH levels, though further investigation is needed to confirm its efficacy.

This review highlights recent advances in dermatology, including innovations in skin cancer treatments, acne and psoriasis management, trends in cosmetic procedures, and the impact of telemedicine, emphasizing ongoing research's role in enhancing patient care and outcomes.

Vitamin D is crucial for skin health and managing skin diseases.

This study found that DPP4 is significantly involved in matrix deposition and fibrosis in human skin fibroblasts, although the exact functions of DPP4 remain unclear.

This study found that mice lacking REDD1 experienced an expansion of dermal white adipose tissue through both hypertrophy and hyperplasia, suggesting a potential therapeutic target for skin adipogenesis regulation.

This study found that BRG1 is crucial for keratinocyte migration during skin wound healing, as its suppression impairs wound closure by inhibiting migration without affecting cell proliferation or apoptosis.

This study suggests that unliganded vitamin D receptors in mice may cause more severe skeletal and mineral ion defects than VDR-null conditions, and vitamin D analogues may restore function in specific VDR mutations.

A man with a rare skin condition and a new gene mutation developed high calcium levels due to his treatment.

This dissertation reported that the loss of Ovol2 impairs hair follicle regeneration and wound repair in mice, highlighting its role in regulating directional migration of epithelial cells.

The document concludes that rapid identification, isolation, and strict infection control are crucial to manage SARS outbreaks.

This case report documents a female toddler with novel compound heterozygous mutations in the VDR gene causing hereditary 1,25-dihydroxyvitamin D-resistant rickets, expanding the known mutation spectrum for this disease.

A man's chest hair turned white after a shingles infection, possibly due to virus-damaged pigment cells.

In this study, a Chinese Han family with hereditary vitamin D-resistant rickets was found to have a homozygous missense mutation in the VDR gene, and the affected individual uniquely responded well to treatment with oral calcium and low-dose calcitriol.

This pilot study found no significant relationship between blood and hair mineral concentrations in generally healthy adults, though hair analysis may have potential for assessing long-term mineral trends.

This case report suggests that systemic lupus erythematosus can be a rare cause of severe hypercalcemia, potentially due to stimulating parathyroid hormone receptor autoantibodies.
