Varicella post-exposure management for pediatric oncology patients.

Introduction: The objective was to evaluate health care providers' (HCP) adherence to and efficacy of varicella post-exposure prophylaxis (PEP) recommendations. It was an observational, prospective, multicenter study set in Ile-de-France, France.

Methods: All children under 18 with a cancer diagnosis, currently or within 3months of receiving cancer treatment, regardless of varicella zoster virus (VZV) serostatus or previous personal history of varicella, were eligible.

French "real life" experience of clofarabine in children with refractory or relapsed acute lymphoblastic leukaemia.

Background: Clofarabine alone or in combination with cyclophosphamide and etoposide has shown a good efficacy and a tolerable toxicity profile in previous studies of children with relapsed or refractory leukaemia. This report describes a retrospective study of 38 French patients who received clofarabine as a monotherapy or in combination for relapsed or refractory acute lymphoblastic leukaemia (ALL) outside of clinical trials after marketing authorization.

Methods: We retrospectively analysed data for 38 patients, up to 21 years old, attending 17 French centres.

Prenatal diagnosis of Crigler-Najjar syndrome type I by single-strand conformation polymorphism (SSCP).

Crigler-Najjar syndrome type I (CN-I) is a rare and severe inherited disorder of bilirubin metabolism, caused by the total deficiency of bilirubin-UDP-glucuronosyltransferase (UGT) activity. Enzymatic diagnosis cannot be performed in chorionic villi or amniocytes as UGT is not active in these tissues. The cloning of the UGT1 gene and the identification of disease-causing mutations have led to the possibility of performing DNA-based diagnosis.

Is a polymorphism of the apolipoprotein E gene associated with preeclampsia?

Objective: Apolipoprotein E (apo E) is pivotal in lipid metabolism. In women with preeclampsia, an atherogenic state is observed. We hypothesized that a particular genotype of apo E may be associated with preeclampsia.
