Accessory Structures of the Skin: Nails

4.1K
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...

Handwashing II: Pre-procedure and Initial Procedure Steps

1.6K
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail...

Summary
This summary is machine-generated.

Artificial nails, including acrylics and gels, can harbor dangerous pathogens like Staphylococcus aureus and yeasts, posing contamination risks. Nail fragility and onycholysis are also potential adverse effects of cosmetic nail enhancements.

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Cosmetic Science

Background:

  • Cosmetic nail enhancements utilize substances that harden via solvent evaporation (varnishes) or polymerization (artificial nails, gels).
  • Pathological reactions to nail cosmetics can manifest remotely (varnishes) or locally (polymerizing substances).
  • Artificial nails, particularly polymerizing types, are associated with increased microbial carriage and potential patient contamination risks.

Purpose of the Study:

  • To investigate the association between artificial nail use and microbial contamination.
  • To examine the impact of cosmetic nail procedures on fingernail health and integrity.
  • To assess the risks posed by artificial nails in healthcare settings.

Main Methods:

  • Review of existing literature on cosmetic nail products and their associated pathologies.
  • Analysis of studies reporting microbial carriage rates in individuals using artificial nails.
  • Examination of clinical signs and causes of fingernail fragility and onycholysis related to cosmetic procedures.

Main Results:

  • Nursing staff wearing artificial nails showed increased carriage of Gram-negative organisms, Staphylococcus aureus, and yeasts, even after cleaning.
  • Artificial nails do not inherently interfere with pulse oximetry readings.
  • Fingernail fragility, fissures, distal doubling, friability, and onycholysis can result from excessive or improper cosmetic nail care.

Conclusions:

  • Artificial nails present a significant contamination risk due to increased microbial carriage.
  • While not affecting pulse oximetry, artificial nails necessitate careful consideration in infection control.
  • Cosmetic nail procedures, especially aggressive manicuring, can lead to structural damage and pathological nail conditions like onycholysis.
