Accessory Structures of the Skin: Nails

2.0K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

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

Accessory Structures of the Skin: Sebaceous Glands

2.3K
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...

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.

Area of Science:

  • Dermatology
  • Rheumatology

Background:

  • Nail psoriasis is a common manifestation of psoriasis, affecting up to 80% of patients.
  • It is frequently associated with more severe disease, earlier onset, and a higher risk of psoriatic arthritis.
  • Nail psoriasis significantly impacts patients' functional capacity and quality of life.

Purpose of the Study:

  • To review the clinical presentation, evaluation, and management of nail psoriasis.
  • To highlight the correlation between nail psoriasis and systemic disease severity.

Main Methods:

  • Review of clinical features, diagnostic tools, and treatment modalities for nail psoriasis.
  • Discussion of the impact of nail matrix and nail bed involvement on clinical presentation.

Main Results:

  • Nail matrix psoriasis presents with pitting, leukonychia, red lunula, and dystrophy.
  • Nail bed psoriasis is characterized by splinter hemorrhages, onycholysis, oil spots, and subungual hyperkeratosis.
  • Common assessment tools include Nail Psoriasis Severity Index (NAPSI) and Physician's Global Assessment of Fingernail Psoriasis (f-PGA).

Conclusions:

  • Nail psoriasis is a prevalent and often severe manifestation of psoriasis.
  • Effective management requires individualized treatment strategies considering disease extent and patient factors.
  • Early recognition and treatment are crucial for improving patient outcomes and quality of life.
