[Thrombocytopenic idiopathic purpura: predictive factors for chronic disease]

The aim of this study is to determine factors predicting development of chronic thrombocytopenic idiopathic purpura. It was a retrospective study, regarding the cases of PTI diagnosed in "service de medicine infantile C H"pital d'Enfants de Tunis" during 11 years. Acomparison was done between two groups: the first including acute PTI and the second including chronic and recurrent PTI. Factors predicting development of chronic disease were searched by the Fisher test which was significant when p < 0, 05. 33 cases of PTI were diagnosed. The ratio sex was 1.06. The mean age was five years and a half. The disease onset was insidious in three cases; all of them have had a chronic course. An haemorrhagic personnel background was present in three cases. Counselling cause was always petechies and ecchymoses. The mean platelets rate was 14555, 5/mm3. Therapeutics abstinence was carried out in five cases. 20 infants received an initial corticotherapy. The immunoglobulins were prescribed in nine cases, witch six associated to Corticotherapy. Three modes of outcome were discerned: acute PTI [n=23], recurrent PTI [n=4] and chronic PTI [n=6]. Factors predicting development of chronic disease were: haemorrhagic personnel background, an insidious disease onset and the failure of an initial therapeutic abstinence. Acute PTI is the most common. The disease had a chronic or recurrent outcome in 1/3 of cases. The search after factors predicting chronic disease allows an early prognosis. Thus, a best management of the disease can be achieved

[Aetiologies and outcome of bronchiectasis in children: a study of 41 patients]

Bronchiectasis remains an important cause of chronic suppurative lung disease in the developing world. This study is to describe the epidemiological characteristics, clinical features, underlying aetiologies and Outcome of bronchiectasis in the paediatric hospital of Tunis. A retrospective study of 41 children with bronchiectasis was conducted between January 1994 and December 2006. Diagnosis was made in patients with clinical suspicion of bronchiectasis associated with abnormalities on chest X ray [n=37] and/or on high resolution computed tomography [HRCT] [n=36]. Mean age at diagnosis was 5 years 9 months; [range: 6 months-14 years]. Persistent cough and bronchorhea were the most common symptoms. Fourteen patients [34%] had dyspnoea on first presentation, 11 of them [26.8%] had chest deformation and/or finger clubbing. Haemoptysis was noted in only two cases. Mean time to diagnosis from symptom onset was 2.7 years [range: 2 months- 4 years]. The underlying aetiologies were identified in 52% of patients. Cystic fibrosis [17%], previous pneumonic illness [9.7%], primary ciliary dyskinesia [9.7%] and immunodeficiency [9.7%] were the most common causes. After a mean follow-up of 6.6 years, the annual lower respiratory infection rate decreased from 7.2 +/- 3 to 3.1 +/- 2.6 [p<0.05], Twenty one point nine per cent of patients had chronic respiratory failure and five patients required surgery. Delays diagnosis of bronchiectasis remains important in our country. Congenital and indeterminate aetiologies are the most common forms. Prognosis is poor with a high prevalence of chronic respiratory failure

[Cholestasis in infant: a study of the children's hospital of Tunis]

Cholestasis in infant constitutes an heterogeneous group of disease; diagnosis and management are often difficult. The Aim of the study is to describe clinical, paraclinical characteristics and outcome of infants hospitalized for cholestasis in children's Hospital of Tunis. A retrospective study of 94 infants with cholestasis was conducted. Patients were hospitalized in four departments of paediatrics of our hospital between January 1995 and December 2005. Cholestasis complicating severe sepsis and visceral leishmaniasis were excluded. Incidence of cholestasis was 8.5 cases/year which represented 0.72% of the hospitalizations. Sex ratio was 1.08 and mean age at diagnosis was 105 days [extremes: 1 day- 24 months]. Biliary atresia was the most common cause of extra hepatic cholestasis [13.8%]. Normal A GT cholestasis [11.7%], benign neonatal cholestasis [11.7%] and bile duct hypoplasia [9.5%] represented the most common aetiologies of intra hepatic cholestasis. Aetiology remained unknown in 12.7% of cases. Only three infants with biliary atresia had Kasai operation. After a mean follow-up of 6 years, 18% of patients had portal hypertension, 14.8% had hepatic failure and mortality rate was 14.8%. Cholestasis of unknown aetiologies are frequent in our hospital. Poor prognosis, in our study, is due to delay to diagnosis and difficulties in medical and surgical management

[Helicobacter pylori infection in childhood revealed by hematemesis endoscopic and pathologic patterns]

Helicobacter pylon infection frequency in hematemesis was scarcely studied. To asses the frequency of this infection in children with upper gastrointestinal bleeding and to study the endoscopic and histological features. It is a retrospective study including 180 children who underwent an endoscopy for upper gastrointestinal bleeding. Our population was divided in two groups. The group 1 [n=95] has performed gastric biopsy. The group 2 [n=95] has performed gastric biopsy. For each group, we studied the personal and familial history of gastroenterologic disease, the hospital where they come from, the importance of bleeding, the gastro-agressif drugs intake, the endoscopic and histological features. The helicobacter pylon infection was present in 48%of the children. The mean age of these children was 99.8 +/- 42.1 months versus 95.7 +/- 44 months [p=0.13]. The comparison of the two groups according to Hp infection, and the others parameters don't found any differences. All the infected children have chronic gastritis 40/40 versusl3/44 in the non infected children [p>10-6]. The frequency of Hp infection was high in this group of patients with upper gastrointestinal bleeding. It was probably underestimated because the investigation was not complete. We emphasize that Hp infection has to be investigated and systematically eradicated whenever there were severe symptoms like hematemesis indicating therefore organic disease

[Chronic gastritis in children]

Active gastritis, atrophic gastritis [AG] and intestinal metaplasia are lesions associated with Helicobacter pylon [H. pylon] infection in adults. To assess the prevalence of chronic gastritis, its histological characteristics and clinical features in children. 345 children [M/F: 151/194, mean age: 8.6 +/- 3.7 years; range: 1-18 years] were enrolled, referred for upper gastrointestinal endoscopy [UGI endo] with clinical manifestations of gastritis, i.e., recurrent abdominal pain [n=232, 67.2%], upper gastrointestinal bleeding [n=59, 17.1%] and miscellaneous [n=53, 15.3%]. Four per-endoscopic gastric biopsy specimens [antrum: 2, fundua: 2] were taken. Biopsies were assessed and graded according to the updated Sydney system. H. pylon infection was considered if 2 out 3 tests were positive [culture, histology and rapid unease teat], whereas 3 concordant negative results identified H. pylon negative children. H. pylon infection and chronic gastritis were detected in 215/345 [62.3%] [M/F. 104/1 17, sex ratio M/F=0.89] and 221/345 [64.05%] children, respectively. Recurrent abdominal pain [n=149, 67.4%] was the main clinical features of chronic gastritis followed by vomiting [n=43, 19.5%] and upper gastrointestinal bleeding [n=4l, 18.6%]. Any clinical features were however found to be specific. UGI endo showed; nodular gastritis [n=90, 40.72%], congestive gastnitis [n=84, 38%], gastric ulcer [n=9], bulbar ulcer [n=5] and normal [n=47, 21 2%]. Chronic gastritis was active in 115 cases [52%] and was significantly associated with nodular gastritis [p<0.05]. Thirty two chronic gastnitis [14.4%] exhibited AG [M/F: 16/16, mean age: 9.4 +/- 3.4 years] and 30/32 [93.7%] were H. pylon positive. AG was significantly associated with H. pylon infection [p<0.0001] and nodular gastritis [p<0.005]. Active, follicular and AG were significantly associated with H. pylon infection [p <0.00001]. Three patients exhibited intestinal metaplasia. Chronic gastnitis is frequent in children. Any clinical features were found to be specific. It significantly associated H. pylon infection and nodular gastnitis. Atrophic gastnitis was found in 145%of children
