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

Accessory Structures of the Skin: Hair Growth and Types

3.0K
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...

Proliferative Phase01:20

Proliferative Phase

1.7K
The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...

Ovarian Cycle01:27

Ovarian Cycle

5.0K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Menopause01:28

Menopause

5.1K
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

798
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

4.3K
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...

Summary
This summary is machine-generated.

Postpartum telogen effluvium (PPTE) is often described, but this review found no data to support its common occurrence. The study suggests PPTE may not be a distinct condition due to its undefined and likely low incidence.

Area of Science:

  • Dermatology
  • Trichology
  • Obstetrics

Background:

  • Postpartum telogen effluvium (PPTE) is frequently reported but lacks robust scientific evidence regarding its incidence and pathogenesis.
  • The condition is often assumed to be common among postpartum women.

Purpose of the Study:

  • To critically evaluate existing literature to determine the actual incidence of postpartum telogen effluvium.
  • To ascertain if objective data supports the prevalence of PPTE.

Main Methods:

  • A comprehensive retrospective review of published scientific papers was performed.
  • Analysis focused on studies investigating hair shedding in pregnant and postpartum individuals.

Main Results:

  • No statistically significant data emerged from the reviewed literature to differentiate hair shedding amounts between pregnant and postpartum women.
  • The available studies failed to provide evidence for a higher incidence of hair shedding in the postpartum period.

Conclusions:

  • Postpartum telogen effluvium is not a well-defined dermatological entity with an unknown exact incidence.
  • Based on the literature review, the frequency of PPTE is considered so low and undefined that its existence as a distinct condition is questionable.
