Esophagic atresia type and its association with heart malformations in a Northern Mexico hospital.

Objective: To know the cardiac malformations frequency associated with esophageal atresia and its type in patients of the Children's Specialties Hospital of Chihuahua as well as related sociodemographic characteristics.

Method: The epidemiology, clinic and evolution of patients with esophageal atresia diagnosis who were admitted to this hospital for a period of two years were studied. Variables such as sex, gestational age, birth weight, Apgar score, atresia type, associated congenital malformations, hospital complications and parental related aspects were analyzed.

Cost-benefit of serum pepsinogen screening for gastric adenocarcinoma in the Mexican population.

Introduction And Aim: Helicobacter pylori (H. pylori) is known to be capable of causing chronic inflammation of the gastric mucosa that slowly progresses through the premalignant stages, reaching localized gastric adenocarcinoma (GAC). Its outcome is closely related to the stage at which diagnosis is made.

Kawasaki disease shock syndrome: Unique and severe subtype of Kawasaki disease.

Background: Kawasaki disease shock syndrome (KDSS) is an uncommon presentation of Kawasaki disease (KD). KDSS has been associated with more severe markers of inflammation, coronary abnormalities and i.v.

Vital Signs as Predictor Factors of Intravenous Immunoglobulin Resistance in Patients With Kawasaki Disease.

Kawasaki disease (KD) is the most common cause of acquired heart disease in children. Intravenous immunoglobulin (IVIG) may significantly lower the frequency of coronary artery complications. However, some patients do not respond to initial therapy and are at higher risk of developing coronary artery lesion.

Fractional exhaled nitric oxide has a good correlation with asthma control and lung function in latino children with asthma.

Background: Although the measurement of fractional exhaled nitric oxide (FE(NO)) has been recommended for observational studies and clinical trials of asthma, FE(NO) has not been examined in studies of childhood asthma in Latin America,

Objective: To examine the relationship between FE(NO) and indicators of disease control or severity [asthma control test/childhood asthma control test (ACT/C-ACT), lung function, and exercise challenge test (ECT)] in Mexican children with persistent asthma,

Methods: Children (6-18 years of age) with persistent asthma were consecutively recruited in a tertiary asthma clinic and divided into two groups, e.g. FE(NO) < 20 parts per billion (ppb) and ≥20 ppb.

Seven-year incidence and progression of obesity. Characterization of body fat pattern evolution in low-income Mexico City urban population.

Background: There are no prospective data regarding the natural history of obesity in Mexico. The objective of this research was to investigate the incidence and progression of obesity in a low-income sector of Mexico City and to characterize evolution of body fat pattern distribution.

Methods: We carried out a population-based, prospective survey.

Prevalence of hepatitis B virus infection and related risk factors in a rural community of Mexico.

A cross-sectional survey of the seroprevalence of hepatitis B virus (HBV) markers among healthy people was conducted in San Juanito, a rural community in the northern state of Chihuahua, Mexico. The overall prevalence in 970 people was 6.6% for antibody to hepatitis B core antigen.
