Skin Diseases and Disorders

2.8K
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...

Pigmentation01:19

Pigmentation

2.2K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Epistasis01:39

Epistasis

44.2K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Pleiotropy01:33

Pleiotropy

38.4K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Summary
This summary is machine-generated.

Pityriasis versicolor, a common fungal skin infection, presents as discolored, scaly patches. While generally treatable with antifungals, this review highlights the potential for recurrent infections.

Area of Science:

  • Dermatology
  • Mycology
  • Infectious Diseases

Background:

  • Pityriasis versicolor is a superficial fungal infection caused by Malassezia yeast.
  • It manifests as hypo- or hyperpigmented, scaly patches on sebaceous skin areas.
  • Prevalence in Scandinavia is 0.5%-4%, with risk factors including genetics and immunosuppression.

Purpose of the Study:

  • To review the clinical presentation, diagnosis, and management of pityriasis versicolor.
  • To discuss the factors contributing to its recurrence.

Main Methods:

  • Clinical diagnosis is primary, often supported by microscopic identification of yeast.
  • Microscopy may reveal the characteristic 'spaghetti and meatballs' fungal morphology.

Main Results:

  • The condition typically presents with asymptomatic, slightly scaly patches, though mild itch can occur.
  • Diagnosis is usually straightforward, with effective treatment options available.

Conclusions:

  • Pityriasis versicolor is a common, generally benign skin condition.
  • While treatment is effective, recurrence is a notable aspect that warrants consideration.
