Summary
Onychomycosis, a common nail infection, was clinically diagnosed in 48% of surveyed outpatients in Mexico. Many cases went undiagnosed, highlighting the need for proactive screening in general practice.
Area of Science:
- Dermatology
- Mycology
- Epidemiology
Background:
- Onychomycosis is a prevalent nail infection caused by fungi like dermatophytes, Candida, and molds.
- Early detection and treatment are crucial for managing this condition and preventing complications.
Purpose of the Study:
- To estimate the frequency of onychomycosis among outpatients in private practice across Mexico.
- To identify the prevalence of nail involvement and associated patient demographics.
Main Methods:
- A national survey was conducted in ten Mexican cities involving 12,637 ambulatory patients.
- Patients completed 17 questions regarding onychomycosis, irrespective of clinical suspicion.
- Data was collected from 300 physicians' private offices.
Main Results:
- 48% of patients received a clinical diagnosis of onychomycosis.
- Toenails were most commonly affected (88%), followed by fingernails (5%) and both (7%).
- Nail thickening and aesthetic changes were the primary complaints; diabetes (22%) and hypertension (21%) were common comorbidities.
Conclusions:
- The study revealed a high frequency of onychomycosis in the surveyed outpatient population.
- An intentional search for onychomycosis, with mycological confirmation, is recommended for patients presenting with other complaints.
- Proactive screening can help detect undiagnosed cases in general practice settings.

01:20Candidiasis
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...
01:23Skin 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...

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:15Antifungal 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...
01:29Fungal 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...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
