Papillary Dermis01:11

Papillary Dermis

5.2K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Accessory Structures of the Skin: Hair and Hair Follicles

4.1K
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...

Area of Science:

  • Dermatology
  • Allergology
  • Immunology

Background:

  • Urticaria is a common skin condition characterized by histamine release.
  • Itching (pruritus) is a primary symptom across all urticaria forms.
  • Causes are varied, including allergies, infections, and physical stimuli, with many cases being idiopathic.

Purpose of the Study:

  • To provide a comprehensive overview of urticaria diagnosis and treatment.
  • To highlight the common pathophysiology involving histamine.
  • To guide clinicians in managing various urticaria presentations.

Main Methods:

  • Diagnosis relies primarily on patient history and physical examination.
  • Treatment strategies involve identifying and avoiding triggers.
  • Pharmacological interventions range from antihistamines to advanced therapies.

Main Results:

  • Histamine release is the common mechanism leading to pruritus.
  • Non-sedating antihistamines are first-line treatments.
  • More severe or persistent cases may necessitate systemic steroids, H2 blockers, leukotriene inhibitors, immunosuppressants, or anti-IgE therapy.

Conclusions:

  • Effective management of urticaria is achievable through appropriate diagnosis and treatment.
  • While some forms are transient, chronic urticaria can persist for years.
  • Symptomatic relief, particularly from pruritus, is an expected outcome of treatment.
