Antimicrobial resistance among urinary tract Escherichia coli isolates from inpatients and outpatients in a tertiary care center in São Paulo, Brazil

Abstract

hallucinations is unusual for intoxication with atropine or scopolamine, but could be explained by delayed digestion of non-ground Jimson weed seeds. Postprandial 'inability to vomit', followed by unconsciousness and auditory hallucinations, as reported by this patient, clearly is consistent with tropane alkaloid poisoning, and, together with laboratory results (50 seeds D. stramonium/kg of grain), confirm contamination by Jimson weed to be the cause of this event. Foodborne disease outbreaks are recognized by the occurrence of illness within a variable but usually short time period after a meal, among individuals who have consumed foods in common. Prompt and thorough laboratory evaluation of cases and implicated foods is essential. Food poisoning due to Jimson weed may mimic B. cereus food intoxication and therefore should be considered as a differential diagnosis. The increasing propagation of organic farming with the refusal to use pesticides may increase the occurrence of food poisoning due to Jimson weed in the future. Conflict of interest: No conflict of interest to declare.

Susceptibility to Antibiotics in Urinary Tract Infections in a Secondary Care Setting From 2005-2006 and 2010-2011, in São Paulo, Brazil: Data From 11,943 Urine Cultures

“…The proportion of females (77.6% vs. 69%-88.8% in studies), the female-to-male ratio by age group, the age group most affected (15-64 years: 57.2%) and the first isolated agent ( E. coli , 70.2%) and frequency is very similar to that found in many published studies 2,4,9,10,15,19,20,25,26 . The percentage of E. coli that is isolated from UTIs, according to international literature, is 75% to 95% 15 .…”

“…All studies of this type in Brazil, except for one 10 , are retrospective and exclude many demographic variables, except gender and age, as well as clinical, radiological or laboratory variables, which does not allow multivariate analysis, and thus, greatly reduces the impact of these publications 1,2,4,9,19,20,25,26 .…”

“…The susceptibility of E. coli in 10 Brazilian studies of community-acquired UTIs showed that only TMP/SMX, cephalothin and norfloxacin presented < 80% susceptibility 1,2,4,9,10,11,19,20,25,26 . In addition to nitrofurantoin, to which P. mirabilis presents intrinsic resistance, TMP/SMX and cephalothin were not good options for treatment of UTIs.…”

“…In clinical practice, physicians and their patients commonly insist that urine tests are necessary for the diagnosis of uncomplicated UTIs. The greatest proof of these assertions is evident from retrospective studies in several regions of Brazil, which were only possible because of this “breach of protocol” 2,4,5,9,10,19,20,22,24,25,26 .…”

“…In Fortaleza in the northeast of Brazil, a lower resistance rate of 7.5% was described for norfloxacin ( Araújo et al , 2011 ). In Europe, a multicentric study showed a ciprofloxacin resistance rate from 1.4% to 12.9% ( Schito et al , 2009 ), whereas a higher rate (31%) was registered in the hospitalized population in Ribeirão Preto, Brazil ( Santo et al. , 2006 ).…”
