(from the journal abstract) Objectives: The birth of a high risk infant--such as a very or extremely premature infant--can represent an important traumatic experience for parents. R. DeMier, M. Hynan et al's "Perinatal PTSD Questionnaire" aims at exploring, retrospectively, parent's posttraumatic stress reactions following the birth of a high risk infant. This paper describes the French validation of this questionnaire. Methods: Fifty-two families with a very or extremely premature infant and 25 families with a full term infant responded to the "Perinatal PTSD Questionnaire" and the "Impact of Event Scale" when children were 18 months old. Results: Parents of high risk infants can present posttraumatic stress reactions such as intrusion, avoidance or arousal symptoms. The French version of the "Perinatal PTSD Questionnaire" has satisfactory psychometric properties. Conclusions: As posttraumatic reactions are not directly related to objective descriptions of the stressful event, it may be essential to the liaison child psychiatrist to consider individual posttraumatic reactions in order to optimise preventive intervention with the parents. A questionnaire should not replace a clinical interview, however it may represent a useful screening tool. Also, this questionnaire should be useful for research purposes.

BACKGROUND: To perform a comprehensive study on the relationship between vitamin D metabolism and the response to interferon-α-based therapy of chronic hepatitis C. METHODOLOGY/PRINCIPAL FINDINGS: Associations between a functionally relevant polymorphism in the gene encoding the vitamin D 1α-hydroxylase (CYP27B1-1260 rs10877012) and the response to treatment with pegylated interferon-α (PEG-IFN-α) and ribavirin were determined in 701 patients with chronic hepatitis C. In addition, associations between serum concentrations of 25-hydroxyvitamin D(3) (25[OH]D(3)) and treatment outcome were analysed. CYP27B1-1260 rs10877012 was found to be an independent predictor of sustained virologic response (SVR) in patients with poor-response IL28B genotypes (15% difference in SVR for rs10877012 genotype AA vs. CC, p = 0.02, OR = 1.52, 95% CI = 1.061-2.188), but not in patients with favourable IL28B genotype. Patients with chronic hepatitis C showed a high prevalence of vitamin D insufficiency (25[OH]D(3)<20 ng/mL) during all seasons, but 25(OH)D(3) serum levels were not associated with treatment outcome. CONCLUSIONS/SIGNIFICANCE: Our study suggests a role of bioactive vitamin D (1,25[OH](2)D(3), calcitriol) in the response to treatment of chronic hepatitis C. However, serum concentration of the calcitriol precursor 25(OH)D(3) is not a suitable predictor of treatment outcome.
