Pneumocoocal infection and haemolytic uremic syndrome

Hemolytic uremic syndrome, one of the common causes of acute renal failure in children, is characterized by the triad of microangiopathy, haemolytic anemia, thrombocytopenia and acute renal failure. The diarrhoea-associated Hemolytic uremic syndrome is usually termed as a typical Hemolytic uremic syndrome. Streptococcus pneumoniae is an uncommon etiological pathogen for inducing Hemolytic uremic syndrome, and Streptococcus pneumoniae associated Hemolytic uremic syndrome is also termed as atypical hemolytic uremic syndrome. To report two pediatric cases of invasive S pneumoniae complicated with hemolytic uremic syndrome HUS. The first patient presented with pneumococcal pneumonia and empyema and the second patient presented with pneumococcal pneumonia and meningitis. The two patients were under one year of age and required peritoneal dialysis with improvement of renal function in one; the other died. Pneumococcal invasive disease may be a cause of severe 1-IUS, so a high index of suspicion is mandatory to prompt appropriate diagnosis and management

kyste hydatique du poumon chez l'enfant a propos de 54 cas

The purpose of this retrospective study is to clarify the clinical, radiological and evolutionary aspects of the hydatid cyst of the lung. Over a period of 9 years [January, 1983 - December, 2001], we brought together in the pediatric service B of Children's hospital of Tunis, 54 cases of hydatid cyst of the lung. The average age is of 7 years 3 months [extremes 2 and 14 years], and the sex- ratio of 1, 16. 61% of the children are of rural origin. Bronchpulmonary infection is the most frequent circumstance of discovery [72% of cases], hemoptysis is revealing in 37% of cases. Discovery is fortuitous in 7% of cases. The radiography of the chest is of a big diagnostic contribution. The radiological aspects obtained are: a homogeneous opaqueness [61%], a diverse opaqueness [26%], an image of lung abscess [22%], an aspect of floating membrane [4%], a pleural effusion [9%], and an opaqueness with growing gas [4%]. Chest echography was contributory in 77% of cases. 74% of the children were operated without complications. The others were lost
