This study reports a novel LC/MS method that separates and analyzes all known ceramide subclasses in human stratum corneum, identifying a new subclass, CER [EOdS], with minimal sample preparation.

This study found that mice deficient in ceramide synthase 4 showed altered sebum composition and progressive hair loss due to obstructed hair canals.

This study found that inactivating CerS4 in mice led to hair follicle stem cell exhaustion and hair loss, indicating its role in regulating hair regeneration through ceramide composition and signaling pathways.

This study observed that in Japanese females, hair lipid composition showed significant correlations, suggesting CH and CERs may act as a barrier against sebum-derived lipids.

Ceramide Synthase 4 is crucial for healthy skin barrier function.

This study found that deleting ceramide synthase 4 in skin epidermis stem cells disrupts hair follicle and skin barrier function, leading to immune responses similar to atopic dermatitis, due to imbalances in lipid composition affecting differentiation.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This study found that inactivating CerS4 in mouse epidermis disrupts lipid homeostasis and is crucial for maintaining, but not forming, the skin barrier.

This study observed that inducible deletion of the Ugcg gene in mouse epidermis led to a significant reduction in GlcCers and epidermal POS-Cers, causing impaired skin barrier function and delayed wound healing.

This review describes the approved use and adverse effects of gefitinib in patients with advanced non-small cell lung cancer, without presenting new clinical findings.

This commentary highlights the importance of additional sun protection for individuals with alopecia, noting that common headwear like baseball caps may provide insufficient photoprotection for the scalp.

This study observed that melanoma survivors had higher odds of using sunscreen and seeking shade compared to cancer-free individuals, but their overall adherence to sun protection was less than expected given their elevated risk for new skin cancers.

This review discusses the perimenopause, its symptoms, and management options, emphasizing the role of pharmacists in educating and advising women on treatment strategies and preventive health measures, but it reports no new results.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.

In a guinea pig model of dermatophytosis, this study found that subcutaneous CD101, dosed once weekly, demonstrated significant clinical and mycological efficacy compared to the vehicle control and the oral antifungal terbinafine, suggesting potential for CD101 in treating fungal skin infections.

This study found that topical Vorinostat induced significant hair regrowth in mice with alopecia areata, suggesting it as a potential repurposable treatment for the condition.

This study identified a new PNPLA1 mutation in a Spanish family with autosomal recessive congenital ichthyosis.

This review discusses the topical use of systemic drugs for cutaneous disorders and reports a lack of strong evidence from randomized controlled trials, highlighting the need for larger comparative effectiveness studies.

This review discusses the potential link between long-term transdermal exposure to sex hormones from antiperspirants and increased breast and prostate cancer rates, calling for further research to confirm this theory.

This discussion highlights that alopecia areata incognita is challenging to diagnose and treat, with systemic corticosteroids potentially leading to remission when local treatments fail.

This review discusses the diagnostic challenges of androgen and estrogen-secreting adrenal tumors and highlights that the presence of metastases is the most reliable indicator of malignancy; it reports no new clinical findings.

This study found that in Japanese, German, and American females, changes in hair lipid patterns with age may reflect alterations in sebum excretion and affect hair texture.

This case report describes a 12-year-old boy with severe skin scaling due to novel compound heterozygous null truncation mutations in the TGM1 gene, resulting in loss of transglutaminase 1 activity.

This study in a Pakistani family identified a novel ST14 gene variant as the likely genetic cause of autosomal recessive ichthyosis with hypotrichosis syndrome.

This study identified significant morphological and sensory differences among 19 genotypes of Ziziphus jujube Mill. grown at the Slovak University of Agriculture, suggesting potential applications in organic agriculture and other practices.

This study reports new fluorogenic ceramidase substrates and highlights RBM14C24:1 as an efficient substrate for neutral ceramidase, while RBM15C18:1 is the best probe for measuring ACER1 and ACER2 activities, potentially aiding high-throughput screening for ceramidase inhibitors.

This case report illustrates that a diagnosis of Cronkhite-Canada syndrome can be made without the presence of polyps, as demonstrated by resolving symptoms with steroid treatment.

This review highlights current and future AI applications in hair restoration and diagnosis of hair disorders, including automated systems for hair detection and self-diagnosis, emphasizing the need for experts to understand their benefits and limitations.

The editor suggests removing "race" and "ethnicity" from dermatology and creating tools to objectively assess skin color and hair texture.

The abstract reports no new results but discusses Berry's belief that most changes in breast cancer incidence are due to screening, measurement adjustments, or hormone use.
