A deep learning model was developed to help diagnose trichothiodystrophy by analyzing hair patterns.

This article illustrates various hair shaft defects and suggests that dermatologists can diagnose most of them using light microscopy and polarization without needing advanced imaging techniques.

This report describes a new case of isolated trichothiodystrophy with characteristic brittle hair and suggests a simplified classification scheme for understanding sulfur-deficient hair disorders.

This study suggests that clinically apparent fragile hair in children is rarely linked to trichothiodystrophy, and the tiger-tail pattern is not wholly specific to this diagnosis.

This case report describes a patient with trichothiodystrophy presenting with autism, mental retardation, and seizures, characterized by distinct hair abnormalities under microscopy.

The researchers reported two brothers with a new variant of X-linked trichothiodystrophy associated with an RNF113A gene mutation, highlighting features such as intellectual disability and growth failure, but without previously reported endocrinological or genital abnormalities, underlining the importance of genetic counseling for such variants.

This case report describes a 3-year-old boy with trichothiodystrophy, highlighting specific MRI findings of diffuse dysmyelination and osteosclerosis that may be unique to the disorder.

In this study, researchers found that trichothiodystrophy hair brittleness is linked to abnormalities in sulfur content and structural organization, making it prone to breakage.

In this study, researchers identified a gene expression pre-pattern and implicated the Wnt inhibitor Dickkopf 4 in the formation of color patterns in domestic cat embryos.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

This article discusses the development of skin patterns during embryogenesis and postnatal life, linking them to genetic, environmental, and mathematical factors, but presents no new empirical findings.

This review discusses the advantages and limitations of various hair loss evaluation methods but reports no new results; it emphasizes the importance of cautious interpretation for these diagnostic tools.

Polarized microscopy is a quick and free method to correctly identify types of hair loss.

This review explores finasteride's effects on neuroactive steroid levels and their potential influence on disorders like depression and alcohol withdrawal but reports no new clinical findings.

This article reviews various causes and investigative techniques for different forms of alopecia and reports no new findings.

This article reviews common dermatologic conditions seen in primary care, such as acne and skin cancer, but reports no new findings.

This review discusses recent advances in trichoscopy for differentiating types of alopecia and presents a systematic approach for using its diagnostic findings, but reports no new clinical results.

This article discusses how changes in hair and nails may indicate systemic diseases, but it provides no new results; the authors emphasize their usefulness in clinical diagnosis.

This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.

This study reviews the genetic mechanisms behind cat coat patterns, revealing that specific loci determine tabby variations and suggesting these patterns could unravel broader developmental and evolutionary biology insights.

Understanding tissue self-organization can improve treatments for diseases and advance regenerative medicine.

This review discusses the current therapeutic options for female pattern hair loss and emphasizes the need for managing patient expectations of permanent regrowth, reporting no new clinical results.

This study found that Swiss cattle exhibiting rat-tail syndrome are heterozygous for genetic variants linked to pigmentation and color dilution, likely due to Holstein introgression in the Simmental breed.

This study investigated the hair of German shepherd dogs, revealing variations in color, shape, and band patterns across different body regions, while all hair types shared similar anatomical structures such as continuous, vacuolated medullas and cuticular scales with smooth or rippled margins.

In this study, pediatric patients with overt polyautoimmunity frequently had systemic lupus erythematosus as an index disease, with clustering patterns revealing familial influence on autoimmune disease aggregation.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.

In this article, the authors compile various dermatological conditions that metaphorically reference animal-related visuals, such as "buffalo hump" in HIV-associated lipodystrophy or "leonine facies" in lepromatous leprosy, to enhance learning through mnemonic and visual associations.

This chapter details the causes and diagnostic process of pediatric alopecia, including trichoscopic findings, but reports no new clinical results.

This article reviews the structural similarities and common disorders of hair and nails, highlighting their joint involvement in congenital and acquired conditions, but it reports no new clinical results.

This case report describes a 2-year-old boy diagnosed with trichothiodystrophy, characterized by fragile hair, intellectual damage, diminished fertility, and short stature.
