ABSTRACT
Amoebiasis is a parasitosis, mainly caused by Entamoeba histolytica (E. histolytica). It is a common disease in tropical and subtropical regions. E. histolytica possesses different mechanisms of pathogenicity, and might lead to the invasion and lysis of the intestinal epithelium. Outside of the high-risk regions, acute intestinal amoebiasis is a very rare condition, often leading to misdiagnosis and death, if not promptly treated. We discuss the cases of 18 and 43 year-old men without medical history, who presented to the emergency department complaining of acute abdominal pain along with fever. Following imaging features and clinical presentation, appendicitis and a complicated form of Crohn's disease were respectively suspected. Given the severity of the symptoms, an explorative laparotomy was performed showing in both cases an inflammatory aspect of the intestine. Histological examination concluded intestinal amoebiasis, a diagnosis that wasn't suspected at first. The learning point of these cases is considering invasive intestinal amoebiasis in patients presenting with an acute abdominal syndrome, even with no history of traveling abroad or immunodeficiency.
ABSTRACT
Background - The infections associated with care (IAS) constitute a major public health problem by the morbi- mortality than they generate as well as by their cost to support. The prevention of these infections has become a priority for several years everywhere in the world and in the occurrence in Tunisia. Aim - The purpose of our study is to assess the prevalence of nosocomial infections as well as develop their microbiologic profiles in the different departments of the hospital of FSI Marsa Tunisia and try to highlight the risk factors that can influence these infections Methods - It was a retrospective study about patients with noscomila infection who were admitted in the different care unit of the Hospital of FSI Marsa and this on a period of 6 years from 1 January 2009 to 31 December 2014 Results - We have identified seventy(70) patients having contracted a nososcomial infection during the period of study for 24600 hospital admission, with a prevalence rate of 0.28%. The unit of intensive care had the highest prevalence rate (30%), followed by the general surgery unit (17.1%) and orthopaedics (15.7%). Four bacterial species accounted for almost ¾ of germs isolated: Pseudomonas aeruginosa (22.86%), Staphylococcus ( 15.71%), Klebsiella pneumoniae (15,71 %) and Escherichia coli in 8.75% of the helth care associated infections. Conclusion - Nosocomial infections represent an important indicator of the quality of care. Serious efforts but simple, especially as regards the respect of the rules of aseptic and hand hygiene are effective to significantly reduce the occurrence of infections in hospital.
