This section presents 70 multiple choice questions designed for haematology specialist trainees, covering complex clinical cases and their likely diagnoses, adverse events, and management advice.

This article presents a collection of 70 multiple choice questions designed to assist haematology and core medical trainees with diagnostic and management skills, but it provides no new clinical findings.

In this study, researchers observed that dormant TRP-2+ melanoma cells in bone marrow can interact with CD8+ T cells in tumor-bearing ret transgenic mice, potentially influencing immune responses.

The document concludes that various drugs for men's health issues are in development, with treatments for sexual dysfunction and prostate conditions being the most advanced.

This chapter covers various dermatological drugs, cosmetics, and topical agents, focusing on the properties and uses of propolis, but does not present new clinical findings.

Some new drugs show potential for treating blood cancers but have serious side effects and need more research.

This case study described a girl with vitamin D-dependent rickets type 2A who developed long-standing tertiary hyperparathyroidism, yet this did not hinder the healing of her rickets or normalization of hypophosphatemia; high doses of intravenous calcium were pivotal for recovery.

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 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 minireview discusses a proposed model of the vitamin D receptor that explains how 1alpha,25(OH)2D3 can mediate both genomic and rapid responses through different ligand shapes and cellular locations, without presenting new research findings.

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.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

This study found that DrugNet, a network-based prioritization method, effectively improves drug repositioning tasks, achieving high performance in validation tests and clinical trial comparisons.

This review provides an overview of scalp psoriasis treatments but presents no new clinical results; it highlights various options including coal tar, salicylic acid, corticosteroids, and vitamin D3 analogues.

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 review outlines the oral toxic effects of chemotherapy and stresses the need for evaluating dental health prior to treatment to mitigate these complications, but it reports no new clinical results.

This review discusses advances in protecting against chemotherapy-induced alopecia and reports no new clinical results; calcitriol and cyclosporine A emerged as promising agents in animal models with broader efficacy across multiple chemotherapy drugs.

These guidelines review the management of complications and specific forms of congenital ichthyosis and report no new results; they summarize expert and evidence-based recommendations for clinicians.

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 review discusses recent data on the use of anabolic-androgenic steroids and other steroid compounds and reports no new clinical results.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This review discusses the various roles of RANK signaling in bone remodeling, immune function, and epithelial differentiation, highlighting its potential involvement in cancer mechanisms; it reports no new clinical results.

This review discusses the oral manifestations associated with hematologic conditions and nutritional deficiencies, without presenting new research results; it emphasizes the impact of blood disorders and vitamin deficiencies on oral health.

This article reviews the hormonal pathogenesis and treatment strategies for acne vulgaris, particularly in women with severe or treatment-resistant cases, associating it with hormonal imbalances and hyperandrogenism.

In this study, synthetic vitamin D3 analogs stimulated hair growth and formation of normal hair follicles in nude mice, unlike the natural form 1,25 dihydroxyvitamin D3.

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 found that the protein hairless acts as both a corepressor and coactivator of the vitamin D receptor, influencing gene transcription in a ligand-selective manner.

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.

This review discusses the potential roles of calcium in the regulation of pluripotent and tissue-specific stem cells but reports no new experimental results, highlighting areas for future research.

This case report describes an elderly multiple myeloma patient whose hair repigmentation was associated with lenalidomide use, suggesting hair graying may be reversible.
