[Risk factors for dislypidemia in obese children and adolescents].

Objective: To assess the risk of dislypidemia associated with obesity in children and adolescents.

Material And Methods: A cross sectional study was conducted with 62 obese children (BMI > 95 centile and tricipital skinfold thickness > 90 centile) and 70 non-obese children (BMI 5-85 centile) ages 5-15 years, without chronic diseases. Subjects' characteristics and family background of chronic diseases were collected and a lipid profile was determined.

Nutritional support with nucleotide addition favors immune response in severely malnourished infants.

Background: Adequate nutritional support of severe primary protein energy malnutrition (PEM) is indispensable for achieving normal immune response. However, an ideal dietetic criterion has not yet been established or accepted by the majority of health professionals caring for malnourished infants. Our objective was to demonstrate improvement in immune response in infants with PEM who received starting infant formula with nucleotides.

Peginterferon alfa-2a plus ribavirin for treating chronic hepatitis C virus infection: analysis of Mexican patients included in a multicenter international clinical trial.

Treatment with polyethylene glycol-modified interferon alfa-2a (peginterferon) alone produces significantly higher sustained antiviral responses than treatment with interferon alfa-2a alone in patients with chronic hepatitis C virus (HCV) infection. We compared the efficacy and safety of peginterferon alfa-2a plus ribavirin, interferon alfa-2b plus ribavirin, and peginterferon alfa-2a alone in the initial treatment of chronic hepatitis C. Thirty-two patients were randomly assigned to treatment, and received at least one dose of medication consisting of 180 microg of peginterferon alfa-2a once weekly plus daily ribavirin (1,000 or 1,200 mg, depending on body weight) (n = 14), weekly peginterferon alfa-2a plus daily placebo (n = 6), or three million units of interferon alfa-2b thrice weekly plus daily ribavirin for 48 weeks (n = 12).

Effect of renutrition on natural and cell-mediated immune response in infants with severe malnutrition.

Background: The purpose of this study was to evaluate whether a 4-week nutritional recovery period with a starting infant formula and 3.35 kJ/mL energy density would favorably affect the natural and cell-mediated immune response in infants with severe and primary protein-energy malnutrition.

Methodology: The study included 12 severely malnourished infants, 3 to 18 months of age.

Human papillomavirus in tonsillar and nasopharyngeal carcinoma: isolation of HPV subtype 31.

We retrospectively studied biopsy specimens obtained from 16 patients who had carcinoma of the tonsil or nasopharynx. Polymerase chain reaction testing detected the presence of human papillomavirus (HPV) in 13 samples (81.3%)--six tonsillar and seven nasopharyngeal.
