Vitamins

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...

Fungal Phylum Microsporidia

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Skin Diseases and Disorders

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...

Mutations

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Jaundice

Jaundice

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...

Summary

Viral warts prevalence was higher than expected in rural Mexican children, particularly in adolescents and females. Malnutrition was common but did not correlate with wart occurrence.

Area of Science:

Epidemiology
Dermatology
Pediatrics

Background:

Viral warts are common in resource-limited rural areas.
The link between viral warts and malnutrition in children remains understudied.

Purpose of the Study:

To investigate the prevalence of viral warts (verruca) in children from two rural communities in Oaxaca, Mexico.
To compare the occurrence of warts with the nutritional status of the studied children.

Main Methods:

A cross-sectional study involving 213 children (ages 10.24 years mean) from Santa Catarina Yahuio and Santiago Laxopa.
Assessment included recording wart presence, type, and location, alongside height and weight measurements for nutritional status evaluation.

Main Results:

A total of 14.1% of children had warts, with 80% residing in Yahuio (p = 0.0002).
Warts were more frequent in females, adolescents, and on sun-exposed areas.
Malnutrition was prevalent (all degrees affecting over 60% of children) but showed no positive correlation with warts.

Conclusions:

The study identified a higher-than-anticipated prevalence of viral warts in the studied population.
Factors associated with increased wart frequency include female sex, adolescence, sun-exposed locations, and higher altitudes, potentially linked to ultraviolet light-induced immune suppression.
