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...
Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
Fungal Group Zygomycota01:29

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
Fungal Phylum Ascomycota01:28

Fungal Phylum Ascomycota

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
Overview of Fungi01:29

Overview of Fungi

Fungi are a diverse group of eukaryotes more closely related to animals than other eukaryotes. Fungal cell walls comprise chitin, a polysaccharide that provides structural strength, and glucans, which contribute to flexibility and integrity. Other polysaccharides, such as mannans and galactosans, may supplement or replace chitin in some fungi. These adaptations, along with their preference for acidic environments and tolerance for high osmotic pressure, enable fungi to thrive in various...

Area of Science:

  • Dermatology
  • Epidemiology
  • Mycology

Background:

  • Onychomycosis is the most common nail disease globally.
  • Epidemiologic data from Asia offer unique insights into onychomycosis.
  • Current research is limited by inconsistent data collection methods.

Purpose of the Study:

  • To highlight the need for standardized data collection in onychomycosis research.
  • To propose the development of a common protocol for studying onychomycosis in Asia.
  • To enhance the comparability and utility of future epidemiologic studies on nail mycoses.

Main Methods:

  • Review and extrapolation of existing epidemiologic data on onychomycosis in Asia.
  • Identification of limitations due to non-uniform data collection practices.
  • Proposal for a standardized research protocol.

Main Results:

  • Extrapolated data have yielded significant insights into onychomycosis patterns in Asia.
  • Lack of uniformity in data collection compromises the reliability and generalizability of findings.
  • A clear need exists for a unified approach to studying this prevalent nail condition.

Conclusions:

  • Standardized protocols are essential for advancing the understanding of onychomycosis.
  • A common protocol will facilitate more robust and comparable research on nail diseases in Asia and worldwide.
  • Improved data uniformity will strengthen future epidemiologic investigations into onychomycosis.
