This case report describes a 40-year-old woman with Cronkhite-Canada Syndrome whose symptoms, including gastrointestinal issues and skin changes, improved significantly with corticosteroids, co-infection treatment, and nutritional counseling.

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

The researchers observed that in cichlid fishes with different dental structures, tooth replacement accelerated more than three times following tooth extraction, alongside distinct changes in gene expression and cellular interactions over one week, providing insights into tooth regeneration mechanisms in vertebrates.

This review discusses the growing problem of alopecia and suggests that homeopathy, alongside lifestyle changes, may effectively manage different types of hair loss, though it reports no new clinical findings.

This study found that the Foxn1(-/-) nude phenotype significantly influences epithelial progeny in skin, with notable changes in stem cell niches not achievable in other models.

The document concludes that individualized treatments for hair issues are effective, certain hair changes can indicate neurocutaneous diseases, specific lotions improve skin health, laser hair removal works but needs more study on long-term effects, men's cosmetics are diverse, peeling is effective but can have side effects, and facial pigmentation is often due to overactive skin cells.

This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.

The study found that exposing Arbas Cashmere goats to a short photoperiod significantly increased cashmere production by extending the anagen phase of hair follicles, with gene expression changes identified as contributing factors.

In this review, the authors focus on understanding various forms of alopecia, emphasizing that early diagnosis is crucial, especially for scarring alopecia, where follicle changes can become irreversible.

The document reviews various hair and nail disorders, their causes, and treatments, emphasizing the need for proper diagnosis and the link between nail changes and systemic diseases.

In this case report, researchers documented a 19-year-old male professional athlete with acquired trichorrhexis nodosa, noting environmental factors like chlorine exposure during swimming may have contributed to his condition, which improved after advice on hair care changes.

This report describes a child and his father with hereditary hypotrichosis simplex, an uncommon isolated form of hair loss, with no other ectodermal or systemic abnormalities noted.

This study found that activation of the transcription factor Nrf2 in keratinocytes promotes wound healing in mice by expanding hair follicle stem cells, independent of changes in keratinocyte proliferation or migration.

This case study details the progression of a woman's skin conditions, initially diagnosed as acanthosis nigricans and later as mycosis fungoides, with changes in lesion characteristics and distribution over time.

This study developed a transgenic mouse model to explore androgenetic alopecia, finding that inducible COX2 expression led to sebaceous gland changes and hair miniaturization, with reversible effects upon reducing COX2.

In this study, ethanamizuril was found to cause alopecia, biochemical changes, and organ damage at higher doses in rats, with a no-observed-adverse-effect level of 20 mg/kg over 30 days.

Genetic changes in mice help understand skin and hair disorders, aiding treatment development for acne and hair loss.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

Pax9 is crucial for proper tongue surface development and preventing skin-like changes.

This study identified major criteria including ectodermal malformations for diagnosing ichthyosis with confetti, and revealed significant genetic variation in the disease locus within the general population.

This review explores hair signs related to nutrition disorders, such as thin and dyspigmented hair, without presenting new clinical findings; the authors highlight unknowns regarding underlying causes.

This study suggests that specific genetic changes, including mutations in protein-coding genes and noncoding regions, have contributed to the evolution of hairlessness in multiple mammalian species.

This study diagnosed a group of six girls with various ectodermal abnormalities, identifying cranio-skeletal malformations consistent with focal dermal hypoplasia (Goltz syndrome), and found heterozygous mutations in the PORCN gene in two children.

This review discusses the formation and maintenance of hair follicles through dynamic cellular changes and signaling pathways, presenting a comprehensive overview but providing no new experimental findings.

This review discusses the role of epigenetics in colorectal cancer and explains how changes like DNA methylation impact tumor development, but it reports no new results.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

This article reviews the clinical and diagnostic features of hair shaft disorders, emphasizing the role of structured patient assessments and the avoidance of hair trauma, but reports no new results.

This study observed that overexpression of the enzyme ODC in transgenic mice caused hair loss and skin changes similar to human papular atrichia, suggesting that ODC might be involved in a critical hair follicle function pathway.

In this research, RNA expression analysis of scalp biopsies from lichen planopilaris patients revealed changes in specific genes after treatments with hydroxychloroquine, narrow band UVB, or low level laser light therapy, suggesting potential biomarkers and implicating M2 macrophages in the disease's immunopathogenesis.
