This study identifies a new mutation in the Scd1 gene in a strain of Kunming mice, causing skin and hair defects with the mildest impact among similar mutations.

This article reviews the use of dermoscopy in distinguishing temporal triangular alopecia from alopecia areata, emphasizing its role in avoiding invasive diagnostics and ineffective treatments; it reports no new clinical findings.

This review discusses the diagnosis, management, and hormone treatment of transsexual individuals, and examines the risks and effects of cross-sex hormone therapy without presenting new clinical results.

This study found that polymorphism in the STK11 gene does not predict metformin therapy response regarding menstrual regularity and other symptoms in women with polycystic ovary syndrome, despite observed improvements in several health markers post-treatment.

This article discusses the history and understanding of Tay syndrome, recognizing it as a distinct condition related to ichthyotic erythroderma, mental retardation, and brittle hair but reports no new clinical results.

This study reported that EGFR activation leads to suppression of Stathmin, which may promote synchronized entry into catagen in hair follicles, highlighting potential mechanisms involving EGFR in hair cycle transitions.

This case series found that low-frequency repetitive transcranial magnetic stimulation may benefit some patients with trichotillomania, although one of five patients experienced worsening symptoms after treatment.

This study suggests that a specific short sequence repeat in Malassezia restricta may be linked to increased colonization and the development or exacerbation of androgenetic alopecia.

In a pilot study with 21 patients, the niostem device increased hair counts and density and enhanced testers’ self-perception of hair growth at 6 months without reported adverse effects, suggesting potential benefits for androgenetic alopecia.

This paper reviews trichostasis spinulosa and presents a case in a 13-year-old girl, providing no new clinical research results.

This study found that trichoscopic examination can effectively differentiate between alopecia areata and trichotillomania, as specific features such as black dots and exclamation marks favor alopecia areata while hair breaking at various lengths and several unique patterns are exclusive to trichotillomania.

This review describes the clinical features of testosterone deficiency syndrome in aging men but reports no new experimental findings, highlighting the need for clinical recognition and treatment of TDS.

This review addresses concerns about finasteride and high-grade prostate cancers but reports no new clinical results.

This report presents a case where multiple steatocystomas appeared in a psoriatic patient during ustekinumab treatment, suggesting the drug may unmask a genetic predisposition to steatocystoma multiplex.

This report describes a patient with trichothiodystrophy exhibiting both specific hair abnormalities and developmental delay, contributing to the understanding of this rare disorder's clinical presentation.

The document concludes that rapid identification, isolation, and strict infection control are crucial to manage SARS outbreaks.

In this study with mice, simultaneous inactivation of Smad4 and PTEN genes led to rapid development of invasive forestomach squamous cell carcinomas, mirroring human esophageal SCCs.

This study highlights that shock wave therapy for erectile dysfunction is commonly performed by nonurologists in major U.S. metropolitan areas, with high costs and varied treatment protocols.

This study introduced and validated new spectrophotometric methods to simultaneously determine finasteride and tadalafil in Entadfi™ capsules with high sensitivity and without interference from excipients.

This study found that using superficial temporal fascia as an interposition barrier is effective in reducing the incidence of Frey syndrome following superficial parotidectomy, compared to no barrier.

This case report describes a non-mosaic Turner-Syndrome individual with global cerebral atrophy, significant cognitive impairment, and severe treatment-resistant schizophrenia.

Low testosterone levels may lead to more severe COVID-19 outcomes.

Suplatast tosilate successfully treated a woman's systemic sclerosis symptoms.

The document's conclusion cannot be provided because the document is not accessible or understandable.

In this study, epidermal stem cells were found to enhance blood vessel formation and support successful one-step transplantation of tissue-engineered skin in a rat model.

This review examined genetic factors in 46, XY differences/disorders of sex development and found that whole-exome sequencing is more effective than panel sequencing for molecular diagnosis. It identified regional genetic variation and emphasized next-generation sequencing's role in detecting variants related to gonadal and androgen-related genes.

In this study, novel mutations in the BTD gene were identified in a patient with profound biotinidase deficiency, highlighting the importance of biotinidase activity measurement and mutation analysis for early diagnosis.

This study found that contrast enhanced phototrichogram (CE-PTG) significantly improved detection of various hair types and growth stages in androgenetic alopecia compared to standard PTG and was comparable to biopsy analysis.

This study found that transgenic mice overexpressing the SSAT gene under a metallothionein promoter suffered delayed hair loss and were highly sensitive to polyamine analogues, which led to significant liver changes and mortality.
