This case report aims to raise physician awareness about 'toe-tourniquet' syndrome, which can lead to digit loss if not promptly treated, and to prevent its misdiagnosis as child abuse.

This study expands the Drug Ontology to include therapeutic indications for resistant hypertension, malaria, and opioid abuse research, providing a framework for additional drug use representations beyond their original design.

This review covers gynecologic examination challenges and normal anatomical variations in prepubertal girls, emphasizing the importance of distinguishing common benign conditions from rare abuse cases; it presents no new experimental findings.

This article presents four case reports of men with porphyria cutanea tarda and hepatitis C, highlighting associations with polysubstance abuse, primarily alcohol.

This review highlights the various nonmedical uses of anabolic androgenic steroids and associated polypharmacy, suggesting that preventing their abuse should be a public health priority, but it reports no new findings.

This abstract discusses the potential link between unexplained infant crying and tourniquet syndrome, noting the importance of considering underlying causes such as abuse, but reports no new clinical findings.

This article discusses hair tourniquet syndrome, a form of penile strangulation caused by human hair often occurring postpartum, and emphasizes considering both accidental causes and the possibility of child abuse in each case.

Dr. Rasmussen disagrees with Alexander and Schor, emphasizing uncertainty in genital wart transmission and advocating for discussions on potential abuse and referrals in such cases.

The research observed that 40-nm self-assembled nanoparticles enhanced minoxidil penetration in hairy guinea pig skin compared to 130-nm nanoparticles, but this size effect was absent in hairless skin.

This study found no SARS-CoV-2 RNA in the semen and urine of a COVID-19 patient, suggesting possible viral clearance or absence in these fluids.

This study found that sodium valproate effectively stopped or reduced seizures in patients with various types of epilepsy, with best results in absence and myoclonic seizures, though it caused temporary hair loss in some cases.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This study found that alopecia in VDR-null mice persists despite undetectable vitamin D levels, indicating a defect in epithelial-mesenchymal communication due to the absence of ligand-independent receptor function.

This study found that frontal and frontoparietal hair recession is relatively common in women, especially after menopause, and may not indicate abnormal androgen metabolism absent other virilization signs.

This study found that p53 plays a crucial role in regulating apoptosis during hair follicle regression (catagen) in mice, and its absence leads to delayed progression and altered expression of apoptosis-related markers.

This study found that eosinophils are a useful diagnostic feature for alopecia areata, especially when the typical "swarm of bees" lymphoid infiltrate is absent, helping differentiate it from trichotillomania.

This study found that while calcium can substitute for the Vitamin D receptor in maintaining epidermal keratinocyte differentiation, it cannot compensate for hair follicle dysfunction caused by the absence of the receptor.

This study suggests that patients with STSD show a different pattern in androgen activation compared to healthy controls, potentially due to increased 5α-reductase activity and absent prepubertal serum DHEA surge.

This study found that androgen receptor expression varied across different types of skin appendage tumors, with specific expression patterns noted in sebaceous and sweat gland tumors but absent in hair follicle tumors.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study suggests that deep dermatophytosis is a distinct condition occurring in immunocompromised patients, characterized by nodules, an indolent course, and absence of follicular invasion, which resolves completely with systemic antifungal treatment.

This review discusses severe insulin resistance syndromes, highlighting their diagnostic challenges, potential novel therapies like leptin replacement, and suggests metformin and lifestyle changes in its absence; no new clinical results are reported.

This study found that BAF200, a subunit of the PBAF chromatin remodeling complex, is crucial for heart development and coronary artery formation in mice, as its absence led to embryonic lethality with severe cardiac defects.

This study found that negative social attractiveness ratings for bald men by same-aged women occurred only when individuating information about the target was absent, while the physical attractiveness stereotype remained active at an implicit level.

This study found that in anagen hair follicles, the basement membrane zone components showed decreased expression in the lower hair bulb, with a complete absence of BP230 at the dermal papilla junction, suggesting an incomplete hemidesmosome structure in these regions.

This study found that the hHa1-t protein variant, caused by a genetic polymorphism in the hHa1 gene, forms functional keratin filaments despite lacking a complete nonhelical tail domain, explaining the absence of a pathological hair phenotype.

This study concluded that IGF-I receptors are present on hair follicles and sebaceous glands of cashmere and Angora goats, but melatonin receptors are absent.

This study found that Akt2 and SGK3 are crucial for postnatal hair follicle development in mice, as their combined absence led to severe hair growth defects due to disrupted β-catenin-dependent transcriptional processes.

This study found that citrullinated proteins, which are implicated in rheumatoid arthritis, were abundant in outer membrane vesicles from Porphyromonas gingivalis but nearly absent in mutants, validating their approach to citrullinated peptide identification.

This study describes a mouse model for Marie Unna Hereditary Hypotrichosis, identifying mutations in the hairless gene that result in sparse or absent hair and cyst-like hair follicles.
