The current situation of meningococcal disease in Latin America and recommendations for a new case definition from the Global Meningococcal Initiative.

The Global Meningococcal Initiative (GMI) is an international group of scientists and clinicians with expertise in meningococcal disease (MD). It promotes MD prevention through education and research. Given geographic differences in disease epidemiology, prevention strategies (e.

Streptococcus pneumoniae serotypes isolated from the middle ear of Mexican children diagnosed with acute otitis media.

Objective: The aim of this study was to identify the etiology and the serotypes of S. pneumoniae (Sp) in Mexican children with acute otitis media (AOM).

Materials And Methods: The study includessamples frompatientsdiagnosed with AOM at the Federico Gomez Children's Hospital of Mexico (2002-2003),with positive culture for Sp bacteriologically confirmed in middle ear fluid obtained by tympanocentesis.

Genotoxic and oxidative damage induced by Helicobacter pylori in Meriones unguiculatus.

Infection with Helicobacter pylori has been shown to be at the origin of various gastric pathologies. However, it has not yet been established whether the etiology of such diseases, particularly of gastric cancer, is related to the production of free radicals or to mutagenesis. The aim of this study was to determine whether a six-month infection with Helicobacter pylori increased the amount of lipid peroxidation, nitric oxide, and DNA damage in Mongolian gerbils (Meriones unguiculatus).

Clinical outcome of invasive infections in children caused by highly penicillin-resistant Streptococcus pneumoniae compared with infections caused by penicillin-susceptible strains.

Background: In this report based on data from the Institutional Surveillance System during 1994-1998, we document the continuing emergence of drug-resistant Streptococcus pneumoniae strains at the Hospital Infantil de Mexico Federico Gómez in Mexico City.

Methods: We evaluate the clinical course of 49 invasive pneumococcal infection outside the central nervous system (CNS) by a number of factors including the site, severity, and place where the infection was acquired, the underlying health of the patient, and the adequacy of antimicrobial therapy.

Results: An underlying illness was present in 21 of 49 (43%) patients, 37 (75%) patients had taken previous antimicrobial therapy, and 25% of the infections were nosocomially acquired.

[Intravenous diltiazem in the reversion to sinus rhythm in supraventricular tachyarrhythmias].

Unlabelled: The safety and therapeutic efficacy (sinus rythm recovery) of intravenous diltiazem vs verapamil in paroxysmal supraventricular tachycardias (PSVT), and diltiazem vs the Sokolow protocol (i.v. digital and oral quinidine) in recent onset atrial fibrillation (AF) were compared.
