This study found that adolescents carrying the HLA-B27 antigen who engaged in intense physical activity were more likely to develop ankylosing spondylitis, although not all predisposed individuals were affected, indicating other genetic and environmental factors might also play a role.

In this case report, an 8-year-old boy's crusted scalp lesions and alopecia initially mimicking kerion were ultimately diagnosed as Pre-B acute lymphocytic leukemia after histopathological evaluation revealed leukemia cutis.

This case report highlights two instances of alopecia areata, demonstrating diverse presentations, and suggests upadacitinib as a promising treatment option, resulting in hair regrowth within 3–6 months, without worsening sarcoidosis-related skin lesions.

This study found that in male badgers, seasonal molting and hair growth are influenced by cycles of plasma testosterone and thyroxine, with hormones affecting the timing and progression of these processes.

This case report presents the first evidence of significant antigen presenting cells around hair follicles in a patient with alopecia due to active systemic lupus erythematosus.

This review discusses the association between cutaneous paraneoplastic syndromes and internal malignancies, noting that recognition of these skin disorders may help detect underlying cancers, but reports no new research findings.

This report describes a case of scarring alopecia in a 7-year-old girl, highlighting the presence of inflammation without true sclerosis despite normal bone age and negative fungal tests.

This review provides an overview of the molecular evolution of corneous beta-proteins in reptiles and birds, highlighting their distinct genetic origin and role in epidermal structures, but reports no new results.

This study found that the androgen precursors DHEA and androstenedione stimulated androgen-sensitive parameters in the sebaceous glands of the skin in castrated male hamsters.

This retrospective case series reported that pediatric patients with alopecia totalis and subtotalis experienced significant hair regrowth after treatment with the JAK inhibitor upadacitinib, with mild acne as the most common side effect; however, larger studies are needed to establish its efficacy and safety conclusively.

In this study, human bone marrow mesenchymal stem cells were found to affect skin adnexa growth in diabetic burn-injured rats, but the effects were not statistically significant.

Patients with GATA2 deficiency show early skin symptoms that help diagnose the condition.

This study described a case where both alopecia universalis and Crohn's ileitis in a 23-year-old man showed remarkable improvement with the JAK1 inhibitor upadacitinib, highlighting its potential as a treatment for patients with concurrent conditions.

This paper reviews adrenocortical carcinoma, discussing its prevalence, symptoms, diagnosis, and treatment options, but reports no new clinical results.

This review described how skin inspection plays a critical role in diagnosing serious endocrine disorders by identifying various cutaneous manifestations linked to conditions like insulin resistance, diabetes, and hyper and hypothyroidism, highlighting its significance in early, life-saving detection.

This case report describes the first known instance of congenital atrichia combined with situs inversus and mesocardia in a 2-year-old male.

Canine skin has two main layers: the epidermis and dermis, with a supportive subcutis layer.

This case study reports a 33-year-old man with autoimmune thyroiditis and alopecia universalis experiencing reversible CNS demyelination, possibly due to autoimmune activity against CNS antigens.

Oral JAK inhibitors are safe for alopecia areata, but baricitinib may cause more acne and infections.

This study discusses calcinosis cutis and alopecia totalis, highlighting the need for thyroid disease screening in children with alopecia areata, especially those with a history of Down syndrome or signs of potential thyroid dysfunction.

This study found that adults with sickle cell anemia exhibited androgen deficiency due to primary testicular failure, and there was a significant correlation between erythrocyte zinc levels and serum testosterone.

Hair loss is often linked to thyroid problems, especially in women and older people, and screening for thyroid issues is advised for those with hair loss.

In this study, researchers found that alpha-keratin homologs similar to those in mammalian hair are present in the claws of the lizard Anolis carolinensis, suggesting a structural role during claw formation.
