This quiz article provides a series of dermatological diagnosis questions based on a Journal of Investigative Dermatology article and includes explanations but reports no original research findings.

In this thesis, researchers explored ways to enhance the management of myotonic dystrophy type 1 by investigating the genetic inheritance patterns, especially small-sized repeat expansions, and assessing cardiac care, energy expenditure, and body composition in affected individuals.

This case report details a middle-aged man with multiple sclerosis who developed difficult-to-evaluate skin reactions after daclizumab treatment, noting only slight improvement with additional therapies.

This study demonstrated that AtVLN4 plays a role in root hair growth by regulating actin organization in a calcium-dependent manner.

This description of dystrophy hypotrichosis associated with juvenile macular dystrophy provides an overview of this rare disorder characterized by short hair from birth and progressive loss of central vision but reports no new 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.

This case report describes a young adult female with late-stage Vogt-Koyanagi-Harada disease featuring panuveitis, retinal detachment, hearing loss, alopecia, and vitiligo, who was successfully treated in a hospital.

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.

In this case study, a rare viral infection called trichodysplasia spinulosa was diagnosed in a 10-year-old girl post-kidney transplant; she was treated successfully with reduced immunosuppression alongside leflunomide and valganciclovir, though the efficacy of valganciclovir remains uncertain.

This study identified a novel pathogenic splice-site variant of the LAMB3 gene in patients with junctional epidermolysis bullosa, highlighting the importance of gene sequencing for diagnosis.

Hair loss might be the first sign of dengue fever.

This study presents a case of a pubertal girl with type 1 diabetes who developed proliferative diabetic retinopathy shortly after diagnosis, suggesting the need for earlier screening in high-risk groups.

In this study, gene therapy using a VDR-expressing adenoviral vector promoted hair growth in Vdr-KO rats, suggesting its potential for treating alopecia associated with type II rickets.

This study found that Prdm1 is crucial for whisker development in mice, affecting multiple signaling pathways and possibly playing a role in primates' evolutionary loss of vibrissae.

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 study identified a 14,883 bp genomic deletion affecting the Plcd1 and Vill genes as likely responsible for the abnormal phenotype observed in snthr-1Bao mice.

This case report identified dystrophic anagen effluvium as a previously unreported dermatological side effect of PEG-INF-α-2a/RBV combination therapy in a patient with chronic hepatitis C infection.

In this case report, researchers observed that local radiation therapy to the orbits may not be sufficient to halt progression of new retinal lesions in older patients, even when the disease initially appears confined to the intraocular space.

In this study, the DLQI demonstrated reliable psychometric properties and a unidimensional structure for assessing health-related quality of life in Brazilian patients with various skin conditions.

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 study found that two unrelated domestic shorthair cats had novel DSG4 gene mutations causing defective hair shafts, representing the first report of pathogenic DSG4 variants in domestic animals.

In this case study, a neoadjuvant therapy combining gemcitabine and Disitamab Vedotin proved effective and safe for a muscle-invasive bladder cancer patient with severe renal insufficiency, who could not tolerate platinum-based treatments. The study suggests this regimen may be a viable alternative, pending further research.

This study found that Cannabidivarin (CBDV) promotes neuronal differentiation and inhibits oligodendrocyte maturation via TRPV1 modulation, highlighting its potential in neural stem cell research.

In this study, a 68-year-old man with muscle-invasive bladder cancer and renal insufficiency achieved a partial radiological response to neoadjuvant therapy with gemcitabine and Disitamab Vedotin, without significant adverse events, highlighting a potential alternative for cisplatin-ineligible patients.

This study demonstrated that a ligand-independent action of the vitamin D receptor significantly affects keratinocyte behavior in hair follicles and skin, pointing to its crucial role in maintaining normal hair and skin structures in rats.

Versican in dermal papilla cells is crucial for healthy hair growth.

This study reported that continuous intravenous dextran sulfate was toxic and ineffective as a treatment for symptomatic HIV infection, as it did not improve surrogate markers and caused significant side effects.

A heart transplant patient developed a skin condition called epidermodysplasia verruciformis after taking immune-suppressing drugs.
