The European rose-hip fruit fly Rhagoletis alternata (Diptera, Tephritidae) infests hips of Rosa species. This fly includes R. rugosa, an Asian species now cultivated all over Europe, in its host range. Differences in size and biomass of hips between the ancestral host R. canina and the new host translate into better growth, shorter larval development of(More)
We describe the case of a patient with systemic lupus erythematosus, treated by corticosteroids, who presented during two successive pregnancies with serological reactivation of toxoplasmosis associated with fetal lesions. The first infected fetus died in utero with signs of hydrops. The second fetus was treated in utero with a combination of sulfadoxine(More)
BACKGROUND Indication for intubation and mechanical ventilation in premature infants may be reduced by initiating continuous positive airway pressure (CPAP) in delivery room. POPULATION AND METHODS Immediately after birth, respiratory support with CPAP was given to all infants with gestational age less than 32 weeks. In case of apnea or progressing(More)
OBJECTIVE Since 1986, quantification of G6PD activity has been a routine test for all babies born at the public maternity hospitals of Marseilles. The objective of our study was to determine the prevalence of G6PD deficiency in the population tested and to evaluate the relative risk of neonatal jaundice in newborns with G6PD deficiency. METHODS Neonatal(More)
Idiopathic thrombocytopenic purpura occurring in pregnancy has a risk for the fetus of severe thrombocytopenia. The handling of these cases obstetrically is controversial. Our experience and that derived from reading the literature suggests that counting the number of maternal platelets does not reflect on the risk for the fetus and the neonate. On the(More)
One of the aspects of prematurity in neonates is the respiratory distress syndrome. Although treatment with mechanical ventilation reduced the mortality rate, bronchopulmonary dysplasia still develops in many neonates. We have attempted to reduce intubation and mechanical ventilation by using, in the delivery room, humidified and warmed gas with fractional(More)
Intra-thoracic gaseous collections, pneumodiastinum and pneumothorax, have become more common since the use of positive expiratory pressure, either with spontaneous ventilation or in association with artificial ventilation. In our experience, the occurence rate of such collections has increased from 7 p. 100 in 1970 to 19 p. 100 in 1974, related to the use(More)
PAH clearance was carried out in 12 newborns, hospitalized in the infantile resuscitation unit for respiratory distress. 6 of these children weighed less than 2.5 kg, 4 had hyaline membrane disease, 6 had either amniotic abnormalities or transitory tachypnea, 2 were surgical patients: one right diaphragmatic hernia, one post-operative respiratory(More)
