Aim: To investigate the occurrence of influenza virus infection in parotitis cases in a population of Santa Fe during 2017 and analyze clinical and epidemiological characteristics of the cases. Methods: We studied patients with diagnosis of mumps without age restriction, who came for examination from week 26 to the network of clinicians forming the Sentinel Influenza Unit in Santa Fe. Results: Between epidemiological weeks 26 and 44, 22 clinical parotitis cases we enrolled. The influenza virus was detected in 68.2%, influenza A (H3N2) 93%, and influenza B, 7%. The clinical signs of cases were mild, with an average swelling development of 5 days and no complications. 74% presented with influenza-like illness in tandem with parotitis. Conclusions: This study provides evidence that a proportion of chil...

During January 2-4, 2006, at 13 sites across the city, compliance with the following traffic rules was measured: for car drivers: seat belt use and restricting minors to the rear seat; and for motorcycle drivers: helmet use and not carrying a minor on board. At total of 4 173 cars and 1 013 motorcycles were observed. Only 9% of the car drivers wore seatbelts. Of the 246 cars carrying minors, 56% had a minor in the front seat. Regarding the motorcycles drivers, only 12% wore a helmet and 6.7% had a child on board. When these observations were compared with those of the previous five years, findings showed that over the past three years compliance rates had decreased. The results of this study suggest that most drivers in city of Santa Fe do not obey the stated traffic laws. In order to reduc...

To describe the activity of influenza and assess the morbidity and mortality impact during 2005 to 2010 in Santa Fe, Argentina. Epidemiological and virological indicators were calculated based on sentinel surveillance. Mortality data from patients over and under the age of 65 were analyzed using the integrated autoregressive moving average model and an excess of mortality attributable to influenza was determined. The viral circulation effect on morbidity was measured through the evolution in the proportion of influenza-like illness (ILI) patients. Peak incidence was observed between weeks 23 and 33. An excess of deaths was identified in 2007 among patients over 65 and among those under 65 in 2009, which was related with influenza A(H3N2) and A(H1N1)pandemic virus circulation respectively, associated with a higher proportion of virus recovery and a higher ILI percentage. The sentinel surveillance of influenza is a simple and eff...

That brought the new hypothesis that many of the cases treated as amebiasis, weren't so. To identify E. hystolitica in patients with dysentery, supposed to be caused by amebae. Transversal and observational study performed between March 2005 and November 2007 in the city of Santa Fe, Argentina. Stools from children aged 2 months to 15 years-old with dysentery and direct exams with E. hystolitica/ dispar, were studied with ELISA to detect the adhesin of E. histolytica (adhesin Eh). Permanent stains for amebae were done as well as stool cultures. Clinical data were charted. 75 children were studied; 35 were male and 40, female, with a median age of 3 years-old. All of them presented diarrhea with leucocyte, 73% macroscopic blood on stool and 27% detectable on the microscope. Elisa Eh was positive in ...
