This review discusses the influence of androgens on hair and sebaceous growth, emphasizing that response may depend more on peripheral sensitivity than on hormone levels; it reports no new empirical results.

This review discusses the physicochemical properties, binding mechanisms, and factors affecting corticosteroid-binding globulin (CBG) functions, but reports no new clinical results.

The authors present a case of punctate follicular porokeratosis, suggesting it as a distinct clinical entity distinguished by keratotic lesions originating specifically from hair follicles.

In this study, researchers identified a novel STS gene (c.287G > A; p.W96*) mutation in Pakistani individuals with X-linked ichthyosis, expanding the understanding of its genetic causes and aiding in genetic counseling.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

This article reports the first case of perforating necrobiosis lipoidica in Colombia and the 19th case worldwide in diabetic patients.

This article discusses topical keratolytic therapy for keratosis pilaris, highlighting potential benefits while noting limitations in the current evidence base, and reports no clinical results.

This source describes the development, structure, and types of skin appendage tumors, noting both benign and malignant forms, potential associations with syndromes, and categories based on follicular differentiation.

This study reports that a new mouse model with a CARD14 mutation successfully mimics key human PRP symptoms, and anti-IL-17A antibody significantly reduces these symptoms.

This case report details the ocular complications of Hutchinson-Gilford Progeria syndrome in a 20-year-old Bangladeshi patient, highlighting symptoms like dry eyes, Meibomian gland dysfunction, and cataracts.

This article describes a case of pilomatricoma in a 22-year-old male with successful surgical excision and no recurrence, highlighting its histopathological features and typical clinical presentation.

The document concludes that proper diagnosis and treatment of follicular disorders are crucial, with specific treatments for conditions like acne, drug-induced eruptions, and rosacea.

The document explains various skin conditions and their treatments.

This case report diagnosed an 8-year-old girl with trachyonychia and secondary onychomycosis, finding that spontaneous improvement is common, making specific therapy often unnecessary despite treatment challenges with associated fungal infections.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

In this study, keratin genes mHa1 and mHb4 were unable to form an extensive keratin network in one cell line, altering endogenous keratin distribution, but showed better integration in another cell line.

This study developed an in vitro model using human follicular keratinocytes to observe selective cell growth and differentiation, potentially aiding future research on hair biology and growth processes.

CTA is often mistaken for AA but doesn't respond to steroids and may require hair transplantation.

In this study, researchers found that alpha-keratin homologs similar to those in mammalian hair are present in the claws of the lizard Anolis carolinensis, suggesting a structural role during claw formation.

Different keratin proteins are expressed in various epithelial cells at different stages, affecting cell structure and function.

This article reviews the molecular characteristics of human hair keratins, noting their distinct classification from epidermal keratins and the variability in expression that may occur without noticeable hair changes, but reports no new study results.

Keratin in mouse hair follicles is complex and plays specific roles.

This study demonstrated that a keratin gel promotes nerve regeneration across critical defects in rabbit models, showing improved nerve conduction and muscle action potential compared to control treatments.
