Infection by Baylisascaris procyonis is an uncommon but devastating cause of eosinophilic meningitis. We report the first case-patient, to our knowledge, who recovered from B. procyonis eosinophilic meningitis without any recognizable neurologic deficits. The spectrum of illness for this organism may be wider than previously recognized.
The cholera epidemic in South America has reinforced the need for safe and effective oral vaccines. In a randomised, double-blind, placebo-controlled efficacy trial among 1563 Peruvian military recruits we have investigated the protective efficacy of an oral inactivated whole-cell/recombinant-B-subunit (WC/rBS) cholera vaccine. Participants were given two(More)
BACKGROUND Recommended treatment for cutaneous sporotrichosis consists of a saturated solution of potassium iodide (SSKI) administered in three daily doses (tid). Because compliance with this regimen has been a problem in our previous experience, we evaluated the use of one daily (qd) full dose of SSKI. METHODS Patients with culture-confirmed cutaneous(More)
The factors influencing the risk of acquisition of Helicobacter pylori infection are not well established. One hundred four children (0-17 years of age) requiring an endoscopy for the evaluation of gastrointestinal symptoms had demographic and dietary data collected and biopsy specimens of the gastric antrum stained for the identification of H. pylori. The(More)
OBJECTIVE Helicobacter pylori induces gastric inflammation and the the production of cytokines in infected individuals. Theoretically, this increased production of cytokines could be deleterious for the control of the glycemia of patients with diabetes. This study aimed to describe the insulin requirement among patients with type 1 diabetes and H pylori(More)
Because of the high prevalence of Helicobacter pylori infection and the morbidity and mortality associated to the disease, development of a preventive vaccine has become a priority. To this goal, we produced recombinant H. pylori urease B (rUreB) and tested its immunogenicity in BALB/c mice when administered as 3 doses (week 0, 4 and 6) by either parenteral(More)
OBJECTIVE To evaluate the palatability, cost and other compliance issues as variables in the selection of antibiotic suspensions for children. METHODS Eighty-six physicians and health care personnel randomly sampled amoxicillin (used as a standard for comparison) and 11 other antibiotics, evaluating them in categories of appearance, smell, texture, taste(More)
By the use of enzyme immunoassay and RNA electrophoresis, rotavirus serotyping was performed with stool specimens from 605 children. Serotypes 1, 2, 3, and 4 accounted for 63, 9, 9, and 19% of the cases, respectively, with considerable yearly variation. An average of three serotypes cocirculated each year.
An outbreak of influenza A pandemic (H1N1) 2009 occurred among campers and staff at a summer camp attended by children with hematologic and oncologic conditions. The overall attack rate was 36% and was highest among children and adolescents (43%), persons with cancer (48%), and persons with sickle cell disease (82%).
BACKGROUND The rhesus rotavirus tetravalent vaccine (RotaShield) had an efficacy of 75%-100% in preventing severe rotavirus disease in prelicensure clinical trials. Before RotaShield's withdrawal because of reports of intussusception, there was an opportunity to evaluate the postlicensure effectiveness of the vaccine. The objective of this study was to(More)
