Accessory Structures of the Skin: Nails01:05

Accessory Structures of the Skin: Nails

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...
Trichomoniasis01:18

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Skin Diseases and Disorders01:23

Skin Diseases and Disorders

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...
Accessory Structures of the Skin: Hair Growth and Types01:20

Accessory Structures of the Skin: Hair Growth and Types

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...

Summary
This summary is machine-generated.

Trachyonychia, or rough nails, involves brittle, ridged nails and can be idiopathic or linked to skin conditions. While challenging to treat, nail abnormalities often resolve on their own.

Area of Science:

  • Dermatology
  • Nail Disorders

Background:

  • Trachyonychia, characterized by rough nails, can be an idiopathic condition or associated with other dermatological issues.
  • Nail findings include brittleness, thinning, and significant longitudinal ridging.

Purpose of the Study:

  • To summarize the key features, diagnostic challenges, and treatment considerations for trachyonychia.

Main Methods:

  • Review of histopathologic features, including spongiosis and inflammatory cell exocytosis.
  • Identification of potential associations with conditions like lichen planus and psoriasis.

Main Results:

  • Common histopathology shows spongiosis and inflammatory cell exocytosis.
  • Lichen planus or psoriasis features may also be present.
  • Identifying the underlying cause of trachyonychia is often difficult.

Conclusions:

  • Treatment for trachyonychia is frequently unsatisfactory and should target any identified underlying cause.
  • In most instances, nail abnormalities associated with trachyonychia show spontaneous improvement.
