[Value of procalcitonin measurement in materno foetal infection]

Materno foetal infection [MFI] remains one of the major causes of neonatal morbidity and mortality. Early detection of neonatal sepsis can be difficult, because the first signs of the disease may be unspecific and similar to symptoms of other non-infectious processes. We aimed to investigate the role of procalcitonin [PCT] in the diagnosis of fetal infection [MFI], and to compare it with those of the C-reactive protein [CRP]. We have conducted a prospective study during 20 months; which concerned 25 new-borns suspected of MFI and admitted before 12 hours of life. All newborn had anamnestic and / or physical signs of possible infection. MFI was confirmed in newborns with positive bacterial analysis. CRP and PCT were determined in the sera at H12, H24, H36 and H48. Newborns were divided into: patients with recognized MFI [group 1], patients with possible MFI [group 2] and non infected newborns [group 3]: The specificity of PCT was 80% versus 27% for the CRP. Negative predictive value of PCT was 85% versus 66% for the CRP. The mean values, at H12, H24, H36 and H48, of PCT for newborn who had MFI were statistically grater than those for no infused group [p <0.05]. No statistical difference was observed concerning CRP values. PCT may a useful tool in early diagnosing of MFI; it has better specificity and negative predictive value than CRP

[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
