Accessory Structures of the Skin: Hair Growth and Types

3.1K
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...

Accessory Structures of the Skin: Hair and Hair Follicles

5.9K
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...

Accessory Structures of the Skin: Sebaceous Glands

5.9K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Skin Diseases and Disorders

6.3K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Acne Infection01:27

Acne Infection

75
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Reticular Dermis01:15

Reticular Dermis

5.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Summary

Physically acting treatments for head lice, including dimeticone and 1,2-octanediol, show effectiveness. This systematic review evaluates various physical treatments for head louse (Pediculus humanus capitis) infections.

Area of Science:

  • Dermatology
  • Parasitology
  • Public Health

Background:

  • Head louse infections are common, particularly in school children.
  • Diagnosis can be challenging due to factors like egg viability and hair length.
  • Risk factors include larger family size and lower socioeconomic status.

Purpose of the Study:

  • To systematically review the clinical effectiveness of physically acting treatments for head lice.
  • To evaluate the safety and efficacy of interventions for Pediculus humanus capitis infestations.

Main Methods:

  • Systematic review of medical databases (Medline, Embase, Cochrane Library) up to March 2014.
  • Inclusion of six studies meeting predefined criteria.
  • GRADE evaluation of evidence quality for interventions.

Main Results:

  • Six studies were included in the systematic review.
  • Evidence quality was assessed using the GRADE system.
  • Effectiveness data for specific physical treatments were compiled.

Conclusions:

  • The review presents findings on the effectiveness and safety of physical treatments.
  • Interventions evaluated include 1,2-octanediol, dimeticone, herbal/essential oils, and isopropyl myristate.
  • Further research may be needed to fully elucidate treatment efficacy.
