Susceptibility to first choice antimicrobial treatment for urinary tract infections to Escherichia coli isolates from women urine samples in community South Brazil

ABSTRACT E. coli is the main pathogen of UTI. It is important to be aware the local epidemiological data for an appropriate initial treatment. Resistance to antimicrobial agents has increased, especially to first-choice antibiotics in the treatment of cystitis. There are few studies on the sensivity profile of community uropathogen in our region. Objective: To characterize antimicrobials the sensitivity profile to E. coli isolated from urocultures of women treated at Basic Health Units and Emergency Care Units of Londrina-Paraná- Brazil during a period of 12 months (June 1, 2016 to June 1, 2017). Methodology: A cross-sectional study was carried out from June 2016 to June 2017. All urine samples collected in the Basic Health Units and Emergency Departments in the city of Londrina (Paraná State, Brazil) were sent to a Central Laboratory where the identification and antimicrobial susceptibility testing were performed. Clinical Laboratory Standards Institute (CLSI) breakpoints were used for the interpretation of susceptibility testing results. Results: 56,555 urine cultures were performed in the period, of which 8,832 were positive, of which 5,377 were women. Of these samples, 4.7% were enterobacteria producing extended-spectrum beta-lactamases (ESBL) and 15.5% resistant to quinolones. TMP- SMX was resistant in more than 30% of the samples in all age groups. Among quinolone-resistant isolates, resistance to cephalothin, ampicillin and sulfamethoxazole-trimethoprim was greater than 60%. Nitrofurantoin was the only antimicrobial that showed 90% of sensitivity. Conclusion: The antimicrobials sensitivity profile was similar to that reported in the literature, with TMP- SMX resistance greater than 30% in the studied samples. Nitrofurantoin maintains high sensitivity rates greater than 90%. Resistance to quinolones increases proportionally with age, as well ESBL.

Coproparasitological survey of intestinal parasites in the city of Londrina, Parana, Brazil: a retrospective analysis

Intestinal parasites are a major public health problem. It is important to inform and educate the public about these infections, especially where such data are scarce. This study aimed to determine the prevalence of intestinal parasites from the analysis of medical records of individuals of the city of Londrina. We analyzed 11,641 fecal reports from February 2009 to December 2012. Data were cataloged after the completion of parasitological testing of Hoffmann, Pons & Janer, Faust and Kato-Katz. From 11,641 reports, 19.1% were positive for intestinal parasites. Among those, 52.1% pertained to females and 47.9% to males, with predominance of positivity of 27.1% among children 0-10 years. For the regions studied, the northern region stood out with 35.4% of cases and prevalence of 6.8%. Among the pathogenic protozoa, reports of Giardia lamblia comprised 19.1% of positivity, while hookworms were the most frequent among helminths, comprising 7.8% of positive cases. It follows that poor conditions of basic sanitation contribute to the dissemination of these parasites. Early diagnosis is a determinant of successful treatment. Additionally, epidemiological data may be used to study the risk factors for transmission and may result in measures applicable to improving living conditions in the community

Hyperreactive malarious splenomegaly and aids: a case report

Malaria is endemic in the North of Brazil. However, Hyperreactive Malarious Splenomegaly (HMS) has been rarely described. Splenomegaly in HIV/Aids infection has a large differential diagnosis, but malaria is a cause of gross splenomegaly, regardless of the HIV status. In this paper, we report the case of a 50-year-old man, HIV positive, with massive splenomegaly and multiple malaria infections in the past. He fulfilled the criteria for HMS, received a short course of anti-malarial treatment and weekly quimioprofilatic Chloroquine. In 9 months, he had great clinical and laboratorial improvement confirming the HMS, a rare diagnosis in Brazil.

Estudo da flora bacteriana nasal: estudo preliminar em equipe de enfermagem / Study of the bacteria flora nose: a nursing preliminar study

Há pouca informaçäo sobre o crescimento de microorganismos patogênicos na flora nasal em países tropicais, já que grande parte das pesquisas se realizaram em paises de clima temperado. Neste estudo, identificamos a flora nasal da equipe de enfermagem dos Hospitais universitários de Londrina, correlacionando os resultados com a literatura consultada e disponível
