BACKGROUND Recurrent acute respiratory tract infections (RARTIs) in children are related to IgG subclass deficiencies. The aim of the trial was to evaluate the effect of OM-85 BV in the number of RARTIs as well as in the IgG subclass levels. METHODS This was a randomized, double-blind, placebo-controlled clinical trial. Patients of ages three to six(More)
A 12-year-old female diagnosed with human immunodeficiency virus infection at age 1 was admitted to our hospital with complaints of headache, left hemiparesis, and blurry vision. On admission, her CD4+ count was 97 cells/mm(3) (13%) and her viral load 44,783 ribonucleic acid copies/mL. Treatment had been initiated 3 months before admission with(More)
OBJECTIVE To carry out a pilot study to discover the frequency of colonization in healthy children under five years old and teenagers, as well as the distribution of the different N. meningitidis serogroups isolated from nasopharyngeal samples collected from the population under study. MATERIAL AND METHODS The population included youth between 15 and 19(More)
OBJECTIVE To define epidemiologic relationships to determine the prevalence and potential risk factors for nasopharyngeal colonization by antibiotic-resistant pneumococci, their serotypes and their antibiotic susceptibility patterns in children attending a daycare center (DCC). MATERIAL AND METHODS A prospective cohort study was conducted among children(More)
OBJECTIVE The aim of this study was to determine the prevalence of asymptomatic nasopharyngeal carriage of Streptococcus pneumoniae, which is a major factor in the transmission of this bacterium. MATERIAL AND METHODS Nasopharyngeal cultures were performed on children attending 32 day-care centers in 12 states in Mexico. RESULTS Streptococcus pneumoniae(More)
Abdominal actinomycosis is a rare finding in pediatric patients and its location in the urinary bladder is exceptional. On the other hand, immunodepression can be found in several disorders including that of actinomycosis. The purpose of this study was to report a case of urinary bladder actinomycosis seen in a seven year old girl. No risk factors were(More)
OBJECTIVE To assess the epidemiologic characteristics of invasive pneumococcal diseases (IPD) among a population in a pediatric hospital in Mexico City and analyze mortality-related risk factors, serotype distribution and antibiotic susceptibility related to S.pneumoniae. MATERIAL AND METHODS We performed a retrospective review of IPD cases at a third(More)
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(More)
Mucormycosis (zygomycosis) normally occurs among individuals with predisposing factors such as prematurity, use of broad spectrum antibiotics, metabolic acidosis or advanced stages of immunosuppression. There have been reports of sporadic cases of cutaneous mucormycosis related to predisposing skin lesions and contact with contaminated material such as(More)
