Accessory Structures of the Skin: Hair Growth and Types01:20

Accessory Structures of the Skin: Hair Growth and Types

2.8K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Multipotency and Niche of Bulge Stem Cell

2.9K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Accessory Structures of the Skin: Hair and Hair Follicles

5.2K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Graves Disease II: Pathophysiology

26
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor,...

Folliculogenesis01:20

Folliculogenesis

3.8K
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...

Renewal of Skin Epidermal Stem Cells

2.4K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

Summary
This summary is machine-generated.

Telogen effluvium (TE) is a hair shedding disorder with varied causes. Autoimmune TE is common, presenting with sudden hair loss, scalp pain, and stress triggers, often chronic and intermittent.

Area of Science:

  • Dermatology
  • Trichology
  • Immunodermatology

Background:

  • Telogen effluvium (TE) is a complex hair loss condition with diverse classifications.
  • The autoimmune subtype is frequently observed in clinical practice.
  • Patients typically present with sudden, significant hair shedding.

Purpose of the Study:

  • To describe the characteristics of autoimmune TE.
  • To highlight diagnostic features and patient presentation.
  • To discuss potential management strategies.

Main Methods:

  • Clinical observation and patient history analysis.
  • Differentiating TE subtypes based on clinical presentation and hair shedding patterns.
  • Reviewing analogies with other scalp conditions like alopecia areata.

Main Results:

  • Autoimmune TE is the most common presentation, characterized by sudden hair loss ('by the handful').
  • Patients often report anxiety, scalp sensitivity (trichodynia), and a chronic, intermittent course.
  • Shed hairs predominantly show exogen roots, not telogen roots.

Conclusions:

  • Autoimmune TE is a distinct entity with triggers like emotional stress and associations with Hashimoto's thyroiditis.
  • While etiopathogenesis is unclear, topical corticosteroids may be considered for treatment.
  • Further research is needed for definitive treatment protocols.
