This report describes the first documented case of bullous pyoderma gangrenosum developing on a cesarean section scar, which improved rapidly with oral prednisolone.

This study suggests that type I 5-alpha reductase may also play a role in hair growth, with dutasteride potentially being more potent than finasteride in modulating key hair growth gene expressions.

This report describes two cases where topical squaric acid dibutylester application in alopecia totalis patients led to severe pustular lesions, necessitating systemic prednisolone treatment.

This study observed that hair follicle morphology in dairy cows changes during the peripartum period, with fluctuations in hair follicle width and anagen percentage but no overall marked changes in skin morphology parameters.

This review discusses the genetic basis of ectodermal dysplasia, highlighting that identification of gene pathologies enhances diagnosis and supports prenatal DNA testing, but it reports no new clinical results.

This letter to the editor presents a case of non-Herlitz junctional epidermolysis bullosa associated with a COL17A1 mutation and reports no new clinical findings.

This study suggests that keratin films, which model hair damage sensitivity, remained intact after shampoo and conditioner treatments and showed potential for evaluating hair texture and adsorption.

This case study describes a 3.5-month-old girl with cystic fibrosis who experienced hair and skin depigmentation, which resolved after treatment with pancreatic enzymes and vitamins.

This study found that a simplified classification based on clinical and morphological features may aid in the diagnosis and initial management of inherited keratinizing disorders, although genetic analysis is essential for definitive diagnosis.

Endré Mester is highly regarded as the 'Godfather' of phototherapy.

In this study, lysocellin induced G1 phase arrest in human osteosarcoma cells, but diminished the cytotoxic efficacy of etoposide, while its derivative alopestatin may reduce etoposide-induced alopecia in a rat model.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This case report describes a patient with adrenomyeloneuropathy, highlighting unusual MRI findings of high signal areas in the right striatum.

In this case study, a 23-year-old man initially suspected of having minoxidil-induced pericarditis was ultimately diagnosed with cardiac angiosarcoma, highlighting the need to consider malignancy in cases of recurrent pericarditis in young adults.

In this study, oral administration of strawberry guava extract promoted hair growth in both mice and humans, with active components like adenosine, fructose, digalactosyldiacylglycerol, and pedunculagin contributing by enhancing skin blood flow and activating dermal papilla cells.

This study reports the development of a natural hair-coloring system using size-controlled ink particles from cuttlefish ink combined with chitosan, achieving darker and more uniform black coloration on hair than existing plant-based natural colorants, without the need for metallic mordants.

This review found that adding immune checkpoint inhibitors to cancer treatment regimens likely increases the incidence of specific drug-related skin toxicities in adult Asian patients, highlighting the need for careful monitoring and management strategies.

This study identified a specific hemizygous intronic variant in the MBTPS2 gene associated with IFAP syndrome in a patient, revealing exon skipping and reduced normal transcript expression through long-read RNA sequencing.

This study found that androgen inactivation pathways in scalp sebaceous glands change with age, specifically noting that AKR1C expression, including AKR1C4 previously thought liver-specific, declines with age and is sex dependent, which could impact hair follicle health during aging.

This research reported that AKR1C enzyme expression, particularly AKR1C4, in scalp sebaceous glands decreases with age, suggesting potential age-related changes in androgen metabolism affecting hair follicle health. Additionally, sulforaphane treatment increased AKR1C expression in related cell types.

In this study, researchers found that androgen receptor expression and AKR1C-mediated androgen inactivation, including AKR1C4, are prominent in scalp sebaceous glands, with AKR1C expression decreasing with age and differing by sex, suggesting these changes may impact hair follicle health as people age.

This study investigated a Labrador Retriever with paw pad hyperkeratosis and identified a unique de novo heterozygous missense variant in the GJB6 gene, suggesting its potential role in the condition, analogous to Clouston syndrome in humans, although differences between species may provide further insights.

The study suggests that refractory chronic alopecia areata cases have more infiltrating skin resident memory T cells, and using a JAK inhibitor may be an effective treatment option.

This study notes the ongoing challenge in developing new drugs for androgenetic alopecia, mentioning that both minoxidil and finasteride were originally intended for treating hypertension. Results are not reported.

This study found that calanthoside, a compound isolated from Calanthe species, promotes the proliferation of human hair follicle dermal papilla cells more effectively than minoxidil.

This study reported that ritlecitinib effectively improved hair regrowth in JAK inhibitor-naïve adolescent patients with severe alopecia areata, achieving significant reductions in SALT scores within 24 weeks, but was less effective for patients who had previously been treated with baricitinib.

Chronic refractory alopecia areata has more skin-resident memory T cells, and JAK inhibitors may help reduce them.

This study found that baricitinib was effective and well tolerated for long-term scalp hair regrowth in severe alopecia areata patients, with certain predictors identified for treatment response.

This study found that cataracts, hair changes, short stature, and low bodyweight are key indicators for diagnosing Werner syndrome in patients under 30, differing from older age group symptoms.

In this study at Tohoku University Hospital, 41% of severe alopecia areata patients achieved significant hair regrowth with baricitinib treatment over 9 months, with predictors of better outcomes including shorter disease duration, female sex, initial mild disease, certain alopecia types, and prior IVMP therapy.
