A woman's unique dementia was misdiagnosed, a genetic mutation increases Parkinson's risk with age, and finasteride may help with Tourette syndrome.

In this report, a 19-year-old Japanese man experienced severe and prolonged urticarial reactions following treatment with diphenylcyclopropenone for alopecia universalis, emphasizing the need for caution with potent sensitizers.

This study observed that PCE-DP may improve skin pigmentation by increasing epidermal turnover and inhibiting melanin uptake and inflammation in human epidermal keratinocytes.

This report from the UK reviews the literature on post-menopausal frontal fibrosing alopecia and highlights its under-recognition and distinctive characteristics compared to lichen planopilaris, but does not provide new results.

This article reviews the characteristics and presentation of fibrosing alopecia in a pattern distribution, a form of scarring alopecia similar to androgenetic alopecia and lichen planopilaris, but provides no new clinical findings.

This study found that loss of the folliculin protein delays transferrin receptor recycling, leading to iron deficiency and suggesting a role in the mechanisms of Birt-Hogg-Dubé syndrome.

Among pediatric alopecia areata patients treated with DPCP, this study reported complete hair regrowth in 8.8% and any regrowth in 61.8% after one year, with better outcomes for those with milder initial symptoms and longer treatment durations.

This study found that overexpressing FGF22 in dermal papilla cells enhanced hair follicle stem cell proliferation and viability, while its knockout reduced these attributes, indicating its role in hair follicle regeneration.

Androgens reduce hair growth by affecting cell differentiation and blood vessel formation.

This study found that PDGF-D acts as a potent mitogenic factor in adipose-derived stem cells, enhancing their proliferation, migration, and growth factor expression, suggesting its use as a preconditioning agent for ASC transplantation.

This study found that poly(propylene carbonate maleate) microspheres can successfully prolong finasteride release over 42 days, showing potential for long-term sustained drug delivery.

This review discusses the various roles of skin-resident dermal white adipose tissue in hair growth inhibition, antibacterial responses, and wound healing, reporting no new empirical findings.

The study concluded that poly(propylene carbonate maleate) microspheres effectively encapsulated finasteride, achieving a biphasic release with prolonged drug release over 5-6 weeks in vitro.

This study confirmed that porcine platelet-rich plasma could commercially replace fetal bovine serum due to its higher growth factor levels and effectiveness as a hair growth promoter comparable to existing serum.

This study reported that fibrosing alopecia in a pattern distribution can occur in patients of color, with clinical and histopathological features allowing for an accurate differential diagnosis.

This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

This study found that platelet-derived growth factor signaling is crucial for maintaining the hair follicle dermal stem cell pool and supporting their regenerative capacity.

This study found that dermal papilla cell-conditioned medium can protect against UV-induced skin aging in a mouse model by modulating ferroptosis pathways, highlighting its potential for treating oxidative stress-related skin conditions.

This study found that DEFB1 polymorphisms, specifically the rs1800972 CG and GG genotypes, may predict susceptibility to and severity of alopecia areata.

In this study, a single oral dose of 2,3,4,7,8-pentachlorodibenzofuran in male Fischer rats led to dose-dependent toxicity, resulting in weight loss, hepatotoxicity, and mortality.

This study from North-East India analyzed 21 cases of frontal fibrosing alopecia, noting a high prevalence in post-menopausal women and distinct histological features such as perifollicular lymphocytic infiltrate and hydropic degeneration.

This study found that Frizzled genes Fzd3 and Fzd6 are redundantly involved in controlling hair follicle polarity in mice, but operate through distinct mechanisms, highlighting their complex role in hair orientation.

In this case report, a 22-year-old female was diagnosed with follicular Dowling-Degos disease based on clinical and histological findings, with symptoms including skin lesions confined to hair follicles. The report emphasizes the importance of differentiating this rare variant from similar conditions for proper management.

This report describes a case of fibrosing alopecia in a pattern distribution in a postmenopausal woman, highlighting its distinction from other forms of lichen planopilaris and pattern hair loss.

This study suggests that PDCD4 regulates keratinocyte proliferation and contact inhibition, playing a role in epidermal homeostasis and wound healing.

This article discusses frontal fibrosing alopecia, noting potential connections to lichen planopilaris, but reports no new clinical findings.

This study found that treatment with diphenylcyclopropenone led to more than 75% hair regrowth in 33.3% of patients with alopecia totalis or alopecia universalis, despite notable side effects.

This study suggests that the transcription factor PDF2 in Arabidopsis may link lipid sensing with growth responses to phosphate starvation by acting as a sensor for lyso-PCs through its START domain.

This study found that reduced plasma DIAPH1 levels were associated with polycystic ovary syndrome, suggesting DIAPH1 as a potential predictive factor for the condition.

This laboratory study found that dendrobium officinale polysaccharide (DOP) stimulated hair follicle and hair growth in mice by activating the WNT signaling pathway.
