This article highlights various endocrine disorders and other etiologies linked to alopecia and emphasizes the importance of diagnosing treatable conditions before starting hair loss treatment.

This case report details a 26-year-old woman with diffuse hair loss following treatment for thyroid cancer, subsequent thyroidectomy, and development of hypothyroidism and hypoparathyroidism managed with thyroxin.

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 the nutritional and metabolic problems following bariatric surgery, emphasizing the need for ongoing monitoring and treatment, but reports 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 observed that children with a genetically transmitted defect in the 1,25-dihydroxyvitamin D3 receptor experienced spontaneous healing of rickets as they aged, despite persistent mineral imbalances during treatment.

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 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 report describes a unique case of hereditary vitamin D-resistant rickets (HVDRR) in a dog, caused by a VDR gene mutation resulting in severe hypocalcemia and bone issues, which presented with symptoms similar to those observed in humans.

This review discusses various skin conditions linked with chronic kidney disease and highlights effective treatments but does not provide new clinical results.

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.

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 in SEDA Volume 40 summarizes new adverse reaction data for diuretics published in 2017, highlighting specific risks such as fractures with loop diuretics and hyperkalemia with spironolactone.

In this case report, researchers described how autoimmune thyroid disease can obscure primary hyperparathyroidism diagnosis, emphasizing the necessity of combining imaging, cytology, biochemical assessment, and parathyroid scintigraphy for accurate diagnosis.

In this case report, the coexistence of hypercalcemia and androgen excess in a postmenopausal woman was linked to primary hyperparathyroidism and a suspected androgen-secreting ovarian tumor, underscoring the need for a comprehensive diagnostic approach to identify overlapping endocrine disorders.

In this case report, a four-year-old girl was diagnosed with vitamin D-dependent rickets type II, manifesting as diffuse alopecia, frontal bossing, hypoplastic teeth, and skin-colored papules, due to a genetic mutation causing resistance to 1.25-dihydroxy vitamin D.

This case study reported on a 3-year-old child with vitamin D-dependent rickets type II treated in the Gaza Strip, whose condition deteriorated despite vitamin D and calcium treatments, leading to recurrent chest infections, respiratory failure, and eventual death.

This study in Italy found that APS-1, a rare disorder, is associated with various AIRE gene mutations and most individuals have autoantibodies such as IFNωAbs, which are markers of the condition.

This retrospective study found that a majority of patients with low vitamin D levels also exhibited secondary hyperparathyroidism, highlighting the relationship between vitamin D deficiency and increased parathyroid hormone levels.

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.

This study described the clinical course of six young patients with type 1 autoimmune polyglandular failure, all of whom initially presented with hypoparathyroidism followed by mucocutaneous candidiasis and adrenal failure.

This study found that preventing abnormal mineral ion homeostasis in vitamin D receptor knockout mice stopped bone abnormalities, while the animal's skin phenotype arose from direct receptor effects independent of vitamin D.

In this case report, a girl with autoimmune polyglandular syndrome type 1 experienced stabilized disease and reversal of alopecia universalis after treatment with glucocorticoids and methotrexate.

This article reviews the multifaceted roles of vitamin D beyond bone health and notes its potential involvement in reducing risks of certain cancers and autoimmune diseases, but it presents no new clinical results.

In this study, researchers observed that vitamin D deficiency is common among patients with musculoskeletal pain admitted to the hospital, with particularly low levels found in females.

This chapter reviews pharmacodynamic evaluations in endocrine disorders focusing on oral antidiabetics, insulin analogues, and hormone interactions, but reports no new results.

In this study, pruritus was the most frequent skin disorder observed in hemodialyzed patients, particularly among those undergoing long-term dialysis.

This chapter reviews various adverse effects associated with vitamins, including hypercalcemia from high doses of vitamin A, hair loss from retinoid treatment, and complications with vitamin B6 in Parkinson's therapy, but reports no new clinical findings.

This study found widespread localization of parathyroid hormone-related protein in normal and cancerous canine tissues, suggesting a potential physiological role as a paracrine or autocrine factor.

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