Chronic gastritis associated with Helicobacter pylori in Mexican children: histopathological patterns.

The objective of this study was to analyze the histopathological patterns of inflammation, distribution, severity, and degree of gastric mucosa of Helicobacter pylori (Hp)-infected children in Northern Mexico, as well as the correlation between colonization density and inflammation intensity. We carried out a cross-sectional study of gastric biopsies performed on children ranging from 2 to 17 years of age who underwent upper gastrointestinal endoscopy for diverse gastroduodenal disorders. This study includes only children who were found to be Hp carriers, with positive results for tests of Hp antigens in feces and in gastric biopsy studies.

Immunochromatographic monoclonal test for detection of Helicobacter pylori antigen in stool is useful in children from high-prevalence developing country.

Background: Tests to detect Helicobacter pylori antigens in feces for diagnosis of infection in children demonstrate controversial results. One novel and fast monoclonal test improves diagnostic accuracy in adults, but clinical evidence of its usefulness at pediatric age is insufficient to date. The objective of this work was to evaluate the diagnostic accuracy of this test in a sample of Mexican children.

Background: The need for establishing criteria that facilitate decision-making has lead to search for factors that could predict prognosis and response to treatment for asthma exacerbations.

Objective: To assess which clinical factors are associated with a rapid response to short-acting beta2 agonists during asthma exacerbations.

Patients And Methods: Two hundred and twenty consecutive adults with mild to moderate asthma crisis were included.

Eustachian tube dysfunction in allergic rhinitis.

Objective: To assess eustachian tube function in patients with allergic rhinitis and compare them with a control group.

Study Design And Setting: Tympanometry was performed in 130 patients (260 ears), divided into 2 groups: 80 cases with allergic rhinitis and 50 healthy controls. Cases underwent skin hypersensitivity tests.

Serum lead, cadmium, and zinc levels in newborns with neural tube defects from a polluted zone in Mexico.

Serum lead, cadmium and zinc levels from 31 newborns with neural tube defects (NTD), and 54 healthy controls living in a polluted area in Mexico were estimated using atomic absorption spectrophotometry (AAS). NTD family history was found to be of greater importance in the case group (OR 6.95, 95% CI 1.

Acetic acid test: a promising screening test for early detection of cervical cancer.

Objective: To determine whether the acetic acid test (AAT) could be used as a screening testfor early detection of cervical cancer.

Study Design: A hospital-based study was carried out. A sample of 376 women who attended the early cancer detection program of the Instituto Mexicano del Seguro Social in the state of Durango during 1998 was included.

[Fungal spores in the environment of the asthmatic patient in a semi-desert area of Mexico].

Objective: To analyze the frequency and type of fungal spores in the habitat of sensitized asthmatic patients, its relationship with skin test reactivity to fungi and indoor factors favoring the fungi development.
