This case report describes a 5-year-old girl with biotinidase deficiency who had acute visual loss and gait disturbance but no typical symptoms, responding well to biotin therapy.

In this case report, a patient with Hodgkin's disease treated with ABVD chemotherapy became disease-free, and accompanying granuloma annulare skin lesions also improved.

This study found that while many drugs are reported to cause hair color changes, substantial evidence supporting a true relationship exists mainly for chloroquine and certain cancer chemotherapeutic agents.

This study found that distinct keratin profiles enabled the evaluation of epithelial differentiation in human hair follicles, with mesenchymal cells playing a critical role in epidermoid differentiation of follicular cells.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This study suggests that spiny keratoderma may be an ectopic hair formation on palms and soles, based on keratinization patterns observed using antikeratin antibodies and electron microscopy.

This article describes a case of multiple perifollicular fibromas and suggests that cases previously reported as such might actually be instances of Birt‐Hogg‐Dubé syndrome.

This case study highlights that breast cancer may present as alopecia refractory to usual treatments, indicating the need for consideration of underlying malignancy in such cases.

This review discusses the roles of filaggrin and trichohyalin in keratinocyte differentiation and reports no new results; the authors introduce possible hybrid granules in tongue epithelia.

This case report describes a woman with Becker's nevus and ipsilateral breast hypoplasia who showed breast enlargement after one month of spironolactone treatment, suggesting a link between hypoplasia and increased androgenic receptor activity.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

Fibroblasts help understand androgen resistance at the cellular level.

Minoxidil can cause allergic reactions like burning, itching, and red bumps.

In this study, treatments combining betamethasone and anovulatory steroids significantly reduced testosterone production in women with hirsutism, with many reporting improved hirsutism and acne, although clinical benefit did not consistently correlate with testosterone reduction.

This report describes a case of Ambras syndrome with a chromosomal inversion on chromosome 8, similar to a previous case, but not associated with altered androgen levels.

This study characterized the stress-strain properties of the human scalp and found that its stiffness increases significantly with load, providing valuable insights for planning scalp surgery procedures.

This study reports that flaky skin mice exhibit skin and nail features that closely resemble human psoriasis vulgaris, suggesting they may serve as a natural model for this condition.

In this study, Scalp Immersion Proxigraphy (SIP) was shown to produce more accurate measurements of linear hair growth rate than crude phototrichogram techniques, suggesting SIP's suitability for clinical trials monitoring hair growth.

This study observed that black-haired areas in female Saluki puppies developed hypotrichosis, with dilated hair follicles containing melanin clumps, while white-haired areas remained normal.

In this study, hair anomalies associated with acrodermatitis enteropathica in a young girl improved significantly after two years of zinc therapy.

This case study describes a pregnant woman who developed a pruritic rash with follicular lesions containing yeast-like organisms, resistant to conventional acne treatments.

This study describes a case of generalized trichorrhexis nodosa and finds that defects in alpha-keratin chain formation and low cystine levels in hair may contribute to the condition.

In this controlled study, a pulsed electrical field treatment significantly increased hair regrowth compared to baseline and the control group over 36 weeks, without observed side effects.

This study found that using 2% topical minoxidil before and after hair transplantation may improve graft outcomes by reducing initial shedding in patients with androgenetic alopecia.

Minoxidil helps hair growth, but results vary.

This study describes a co-dominant E410D mutation in keratin hHb6 associated with severe hair loss and extensive papules in homozygous individuals, with variable expression in heterozygous family members.

In this study, treating refractory alopecia universalis with low-dose cyclosporine A and prednisolone improved symptoms, with no recurring alopecia six months post-treatment and enhancements in immunologic function.

This report describes a 15-year-old male with widespread papules due to middermal epithelial cysts containing vellus hairs, also observed in his brother and father.

In this study, researchers found that oestrogen did not increase adrenal androgen secretion in children with premature adrenarche or in adolescents with gonadal dysgenesis undergoing oestrogen replacement therapy.
