This study identified that patients with compound heterozygous mutations in FOXN1 exhibited severe T-cell lymphopenia but retained normal hair and nail development, indicating a distinct clinical phenotype from classic FOXN1 cases.

This study found that in HIV-infected men, erectile dysfunction was influenced by the duration of HIV infection but not associated with serum testosterone or HAART therapy.

This study found that while a transscrotal testosterone patch increases serum testosterone levels in hypogonadal men with AIDS and weight loss, it does not improve weight, body cell mass, or quality of life.

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.

In this study, researchers found that children with alopecia areata exhibited immune system imbalances, including increased autoimmune and allergic markers and decreased phagocytic activity, along with a higher prevalence of autoimmune thyroiditis and allergic rhinitis compared to children without alopecia.

This article reviews the relationship between the skin and the immune system and discusses how skin manifestations can indicate immunodeficiencies but reports no new research findings.

This review summarizes recent findings on FOXN1's essential role in thymus and skin biology and discusses emerging therapeutic approaches for immune disorders with athymia, but reports no new clinical results.

This study found that Aire‒/‒ mice spontaneously developed persistent AA-like lesions, highlighting a potential role for AIRE in hair follicle biology and pathogenesis of alopecia areata.

In this retrospective case–control study, researchers observed that patients with alopecia areata had a higher prevalence of iron deficiency anemia compared to controls, suggesting a potential comorbidity that may require assessment and management.

This review discusses the potential risk mechanisms for COVID-19 in women with polycystic ovarian syndrome due to hyperandrogenism and calls for further research, but reports no new findings.

This study describes the case of a 22-year-old female with alopecia areata linked to vitamin D deficiency, highlighting the importance of early diagnosis and management of deficiency to prevent broader health issues.

This study suggests that while vitamin D3 deficiency is linked to alopecia areata severity, evidence for the effectiveness of supplementation or topical calcipotriol treatment remains inconsistent and low quality.

In this study, a novel homozygous mutation in the STAT5B gene was identified in a 17-year-old boy with growth hormone-refractory growth failure, severe eczema, and autoimmune disease, suggesting a similarity to known STAT5B deficiency phenotypes.

This study reported significant transcriptomic changes in keratinocyte and immune cell populations in a mouse model with EGFR-deficient epidermis, suggesting possible targets for mitigating adverse skin events in EGFR-targeted cancer therapy.

In this study, mouse models with EGFR deficiency showed that disrupted hair follicle cycling leads to increased mast cell numbers and inflammation, suggesting EGFR's role in managing hair cycle transitions and preventing folliculitis.

This study found that human hair follicles serve as a crucial reservoir for Langerhans cells, which repopulate the epidermis depleted by ultraviolet B exposure.

This case report documented a 20-year-old male with alopecia areata who experienced slight hair regrowth following treatment with cyclosporine and methylprednisolone, highlighting the importance of individualized treatment plans and consideration of medication side effects.

This study found that CRP levels were elevated in alopecia areata patients, with an inverse linear association between serum vitamin D and CRP levels specifically noted in ophiasis AA.

In this case report, researchers observed that two sisters with congenital immune disorders experienced partial hair regrowth while receiving tofacitinib for severe alopecia areata, highlighting the need for careful clinical and laboratory monitoring due to potential infection risks associated with JAK inhibitor therapy.

In this case report, an 11-year-old girl with acrodermatitis enteropathica experienced a complete resolution of symptoms following oral zinc therapy, highlighting its effectiveness in managing this condition.

This is the first report of the FOXN1 p.R255X mutation from India, demonstrating the global spread of this genetic mutation previously found only in an Italian community.

This study found that chromosomal microarray analysis identified copy number variations in 12% of patients with dysmorphic features and congenital anomalies, demonstrating its potential as a diagnostic tool, especially for rare CNVs and immune deficiency linked to the deletion of CTLA4.

This review analyzes the molecular and genetic roles of zinc, its connection to diarrheal disease, dietary recommendations, and the impacts of zinc deficiency on health, but reports no new data.

This narrative review discusses advancements in the understanding and treatment of dermatitis herpetiformis as a manifestation of celiac disease and reports no new research results.

This study identified the presence of apoptotic or necrotic keratinocytes and hair shaft dystrophy as potential markers of hair loss in patients with HIV-1 infection.

This review outlines various causes and manifestations of hair loss, highlighting that each type has distinct underlying mechanisms and requires specific treatment approaches, without reporting new clinical results.

This review discusses zinc supplementation as a complementary therapy for chronic hepatitis C, noting its potential benefits in improving treatment outcomes and reducing side effects, but reports no new clinical results.

This review discusses the mechanisms of zinc transport, its role in human health, and the effects of zinc imbalance, without reporting new results.

This journal serves as a platform for diverse perspectives on vaccine-related issues, but the abstract itself reports no new scientific findings.

This case report describes a 25-year-old woman with alopecia areata and nail spooning, which regressed almost completely after treatment with oral corticosteroids.
