Accessory Structures of the Skin: Nails01:05

Accessory Structures of the Skin: Nails

4.4K
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...

Healing II: Complications

21
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Handwashing II: Pre-procedure and Initial Procedure Steps

1.7K
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...

Fractures: Bone Repair

6.9K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Phases of Wound Repair

10.0K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Area of Science:

  • Dermatology
  • Nail Biology

Background:

  • Worn-down nail syndrome is a nail disorder characterized by distal nail plate thinning.
  • It is typically caused by repetitive chemical or mechanical trauma.

Observation:

  • This study describes a novel cause of worn-down nail syndrome.
  • The observed cause is trauma specifically from nail filing procedures.

Findings:

  • Nail filing after acrylic nail removal can lead to worn-down nail syndrome.
  • This repetitive mechanical trauma thins the distal nail plate.

Implications:

  • Highlights a new iatrogenic cause for this nail condition.
  • Informs nail care professionals and consumers about potential risks associated with acrylic nail removal techniques.
