Pancreatic involvement in Legionella pneumonia.

Legionella-associated pancreatitis has been rarely reported. Since this condition is very rarely suspected and investigated in patients with Legionella pneumonia, its incidence is probably underestimated. Here we report a case of Legionella pneumonia-associated pancreatitis and review the relevant related literature.

Prenatal features of Noonan syndrome: prevalence and prognostic value.

OBJECTIVE: Noonan syndrome (NS) is a common autosomal dominant developmental disorder, mainly characterized by congenital heart defects, short stature, and a variable degree of developmental delay. We have reviewed the prenatal findings in NS and we have correlated them with genotype and postnatal phenotype. METHODS: The cohort consisted of 47 patients with molecular diagnosis of NS. Prenatal and postnatal phenotypes were assessed by analysis of medical records, and clinical follow-up. Postnatal clinical phenotype, congenital heart disease, neuropsychomotor development, and growth pattern were arbitrarily scored in terms of severity. RESULTS: Mean age at diagnosis of NS was 7 years (ranging from birth to 38 years). Abnormal maternal serum triple screen was present in 36% of cases, nuchal translucency > 2.5 mm in 41%, polyhydramnios in 38% and fetal anomalies at prenatal ultrasonography in 21%. No statistical association was observed between prenatal findings and NS genotype or scores of postnatal clinical phenotype, congenital heart disease, neuropsychomotor development, or short stature. Presence of morphologic fetal anomalies at ultrasonography was associated with developmental delay/intellectual disabilities (p < 0.001) and juvenile myelomonocytic leukaemia (p = 0.006). CONCLUSIONS: Abnormal prenatal findings are frequent in NS pregnancies, though they are not specific and most are not useful for the prediction of the postnatal phenotype.

[Nosocomial rotavirus gastroenteritis]. / Gastro-entérites nosocomiales à rotavirus : étude rétrospective dans un service de pédiatrie générale.

Rotavirus is the most common cause of gastroenteritis in children requiring hospitalization. It is a very resistant and contagious virus causing nosocomial gastroenteritis. In France, the vaccine against rotavirus has been available since 2006, but the vaccine is not recommended for infant vaccination. The aim of this retrospective study was to describe nosocomial rotavirus gastroenteritis (NRGE) and to assess its impact on children hospitalized in the General Pediatrics Department of Robert-Debré Hospital (Paris) between 1 January 2009 and 31 December 2013. We analyzed the demographic characteristics of children (age, term birth, underlying diseases) and the severity of the NRGE (oral or intravenous hydration), and assessed whether these children could benefit from vaccination against rotavirus. RESULTS: One hundred thirty-six children presented nosocomial rotavirus infection, with an incidence of 2.5 NRGE per 1000 days of hospitalization. The incidence of NRGE was stable between 2009 and 2013 despite the introduction of specific hygiene measures. The average age of the children was 7 months (range: 0.5-111 months). Most often NRGE occurred in children hospitalized for respiratory diseases (65% of cases) and requiring prolonged hospitalization (median: 18 days). One-third of children were born premature (25%). Hydration was oral in 80 patients (59%), by intravenous infusion in 18 patients (13%), and intraosseous in one patient. Half of the patients were aged less than 5 months and could benefit from the protection afforded by vaccination. CONCLUSION: NRGE are common. Rotavirus mass vaccination should have a positive impact on the incidence of NRGE by reducing the number of children hospitalized for gastroenteritis, therefore indirectly reducing the number of hospital cross-infections of hospitalized children who are too young to be vaccinated.
