This review discusses the negative effects of cigarette smoking on various skin conditions and emphasizes the importance of dermatologists advising patients to quit smoking, but it presents no new research findings.

This study found that histopathologic features of erythematous papulopustular eruption due to EGFR inhibitors vary with eruption severity and differ between cetuximab and erlotinib treatments.

This case study reports a 38-year-old epileptic man with tufted hair folliculitis that persisted despite various antibiotic treatments, showing transient improvement followed by recurrence.

In this study, researchers found that finasteride exhibits a solid-solid phase relationship that is enantiotropic at normal pressure and becomes monotropic at higher pressure.

This study determined that previous reports mistakenly identified different polymorphs of furosemide and finasteride, which are actually identical, due to incomplete data collection in single-crystal X-ray diffraction analysis.

This study found that the dissolution profiles of different finasteride polymorphs may affect the quality of finasteride capsules, highlighting the need for polymorphic quality control.

This article reviews the characteristics and diagnostic criteria of tricholemmoma and tricholemmal carcinoma, detailing their clinical presentations and associations but reports no new clinical findings.

This article discusses the structure and protective function of pangolin scales, emphasizing their composition of α-keratins and β-keratins, and highlights evolutionary keratin diversification in tetrapods; it reports no new empirical findings.

Mammalian hair scales change from smooth to wavy due to friction.

This article discusses a hypothesis on the development and evolution of scales, hairs, and feathers from fish to amniotes, based on regions of dermo-epidermal interactions in skin, but reports no new findings.

This perspective highlights the potential of reptile integument as an experimental model to understand the evolution of amniote skin structures, but reports no new research findings.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

Ichthyoses are skin disorders causing scales, with treatment depending on type and severity.

In this study, researchers explored the molecular and cellular traits of avian reticulate scales, finding that they lack localized stem cell niches for regeneration, unlike other scale types, leading to repair but not regeneration after wounding.

In this study, researchers observed that the epidermal specializations on the tail scales of Lygodactylus lizards, including sensory organs and specific secretory glands, are fully restored with similar structure and distribution on regenerated tails.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

This study found that harp seal vibrissal innervation studies focusing only on lateral vibrissae may overestimate total innervation by about 20%, highlighting the importance of considering the entire snout.

Mouse tail skin has different keratinization near hair follicles and scales.

This study provides genomic and epigenomic insights into the white wax scale insect, highlighting high methylation levels and differential hormone profiles linked to its sexual dimorphism and developmental differences.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

This abstract contains only journal subscription and informational content and does not present any research findings.

This review outlines a diagnostic framework for clinicians to distinguish different types of inherited ichthyoses and suggests further testing and treatment strategies, but reports no new clinical results.

This article describes the first documented case of acquired uncombable hair syndrome in a 39-year-old woman, contributing to the understanding of this rare condition.

Early diagnosis of hair tourniquet syndrome saved a baby's toe from being lost.

The book provides an overview of new trends and techniques in cosmetic dermatology.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

In this study, researchers used synchrotron X-ray imaging to examine rat vibrissa follicles, finding that despite variations in vibrissa length and follicle size, certain sensory structures remain consistent, suggesting specialized roles in sensory processing depending on the vibrissa type.
