This case report highlights a rare presentation of hair-thread tourniquet syndrome in a two-year-old child, emphasizing that prompt identification and removal of the constricting fiber is crucial for successful treatment and prevention of tissue damage.

Older adults may experience painful finger pitting due to nerve changes in aging skin, and treatments can help reduce symptoms.

In this study, researchers found that massively parallel sequencing of mitochondrial DNA (mtDNA) can improve information recovery from forensic samples, with successful full region amplification possible from as few as 2,000 mtDNA copies, albeit with variability in heteroplasmy among hair samples from the same donor.

This case report highlights the successful use of platelet-rich plasma infiltration to treat vasopressin-induced bilateral foot digit gangrene in a 20-year-old female, suggesting its potential in stimulating angiogenesis and wound healing, though further research is necessary to assess its general efficacy.

A woman with frontal fibrosing alopecia experienced unusual hair growth after using a specific topical lotion.

This review explores potential new roles for Merkel cells, including involvement in magnetoreception, fingerprint formation, and transmitting environmental information, but reports no experimental results.

This report describes the sonographic characteristics of a proliferating trichilemmal tumor in the subungual region, identifying it as a heterogeneous mass with echogenic foci, potentially representing keratin and cholesterol.

This study found that applying 2% topical minoxidil resulted in a greater nail growth rate compared to 5% minoxidil and placebo over eight weeks, with no observed side effects, suggesting 2% is an effective concentration for accelerating nail growth.

This review outlines various clinical methods for assessing ageing skin and discusses their application in supporting the efficacy claims of anti-ageing treatments, but it reports no new clinical results.

This review discusses the causes and diagnosis of traction alopecia, emphasizing education for high-risk populations as there is currently no cure, and presents no new clinical findings.

This study highlighted that diagnostic complexities can lead to misdiagnosis of alopecia areata in Black patients, commonly due to similar presentations of scarring alopecias and multiple hair loss types co-occurring within a single patient.

This article discusses the histologic features of psoriasis, including psoriasiform epidermal hyperplasia and neutrophilic involvement, but reports no new clinical findings.

This study found that women with lower 2D:4D ratios and fewer middle-phalangeal hairs reported more adverse side effects from oral contraceptives, suggesting these features may predict hormonal contraceptive side effects.

This study found that root hairs in maize, wheat, and finger millet continued to grow beyond the typical root hair zone when grown with the Turface® fertigation system, highlighting potential for understanding root hair dynamics and crop improvement.

This study found that betamethasone valerate in a foam vehicle has comparable total coverage to traditional topical corticosteroid vehicles, despite less coverage per unit of foam.

This review reports on the use of nails as an alternative biological matrix to hair for assessing long-term drug consumption, emphasizing that while there are clear differences between nail and hair samples, more standardized research is necessary for definitive conclusions.

This article presents a case of a seventeen-year-old female with dermatopathia pigmentosa reticularis and emphasizes the importance of distinguishing its clinical features from other similar disorders, supported by dermoscopic and histopathological findings.

This paper discusses the potential of millets as a dietary intervention to help manage chemotherapy side effects in cancer patients, suggesting that their nutrient profile and various health benefits could support treatment without increasing medication burden.

This study found significant correlations between scalp and nail involvement and laboratory findings in Korean patients with chronic cutaneous lupus erythematosus, highlighting their importance for diagnosis and management.

This study found no significant difference in 2D:4D ratios and autism questionnaire scores between acne vulgaris patients and healthy controls, despite investigating potential links in this novel context.

Oral alitretinoin is effective for certain types of chronic hand eczema, with mild side effects.

This study suggests that observing the acute telogen effluvium triad—frontal fringe, temporal recess, and occipital fringe—can aid in diagnosing telogen effluvium during resolution phases, despite challenges like negative pull tests.

This study identified a missense mutation in the human hairless gene associated with a rare form of recessively inherited alopecia universalis, pinpointed on chromosome 8p12.

This study found that the loss of a functional hr gene in mice leads to premature and abnormal hair follicle regression, disrupting normal hair cycling and architecture.

This review examines the dermatologic effects of tobacco use and nicotine, noting potential benefits and drawbacks for various skin conditions, but reports no new clinical results.

This study suggests that basonuclin in keratinocytes is likely a regulatory molecule linked to maintaining proliferative capacity and preventing terminal differentiation rather than a cell cycle marker.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This review discusses the role of the Slug transcription factor in various epidermal functions and its distinction from the related Snail factor, without presenting new research findings.

This review discusses the diverse roles of the TRPS1 gene in regulating cartilage, kidney, and hair follicle development, highlighting its functions and interactions, but provides no new experimental results.

In this study, a deficiency in the zinc finger protein Zfp462 in mice led to anxiety-like behaviors and excessive self-grooming, providing a new model for studying anxiety disorders.
