Resistant variants of the human leukaemic line K562 were developed using selection with the deoxynucleoside analogues cytosine arabinoside, 2-chlorodeoxyadenosine, fludarabine and gemcitabine. The resistant lines displayed a high degree of cross resistance to all deoxynucleoside analogues, with little or no cross resistance to other agents. There was a(More)
The aim of this study was to determine the performances of methods used for the neonatal diagnosis of congenital toxoplasmosis. We included 165 pregnant women infected during pregnancy over a 10-year period. Fifty-seven cases of congenital toxoplasmosis were demonstrated (34.5%). Neonatal diagnosis gave positive results in 50 cases (88%). Parasites were(More)
Two novel point mutations in the 3-hydroxy-3-methylglutaryl coenzyme A lyase gene were found in a French patient with double heterozygous 3-hydroxy-3-methylglutaric aciduria. Amplification by reverse transcriptase-polymerase chain reaction of the mRNA using five different pairs of oligonucleotides produced no differences in the fragments amplified with(More)
A novel nonsense mutation associated with the skipping of constitutive exon 2 of the 3-hydroxy-3-methylglutaryl-CoA lyase gene was found in two patients, from Portugal and Morocco, with 3-hydroxy-3-methylglutaric acidemia. By reverse transcriptase PCR and single-strand conformational polymorphism a G-T transversion was located, at nucleotide 109, of the(More)
OBJECTIVES Survey on the current medical approach to and the economic issues affecting infants with primary hyperoxaluria type 1. METHODS Questionnaire to specialized centers worldwide. RESULTS Seventy-eight infants were identified: 44% were of Muslim origin and 56% were not. The consanguinity rate was 76% and 0%, respectively. Thirty-three percent were(More)
Termination of pregnancy is usually recommended to pregnant women who have infection with Toxoplasma gondii before 26 weeks of pregnancy if the fetus is infected. No prospective studies are available on the outcome if such pregnancies are allowed to continue with anti-parasitic treatment. We prospectively studied 163 mothers with acute toxoplasma infection(More)
To illustrate the clinical and biochemical heterogeneity of peroxisomal disorders, we report our experience with 27 patients seen personally between 1982 and 1997. Twenty patients presented with a phenotype corresponding either to Zellweger syndrome, neonatal adrenoleukodystrophy, or infantile Refsum disease, 3 of whom had a peroxisomal disorder due to a(More)
Canavan disease is a severe, progressive leukodystrophy with an autosomal recessive inheritance, caused by aspartoacylase (ASPA) deficiency. The characteristic MRI features include diffuse, symmetrical white matter degeneration in the subcortical areas, with bilateral involvement of the globus pallidus. Proton magnetic resonance spectroscopy of the brain(More)
Extralobar pulmonary sequestration is part of the spectrum of bronchopulmonary foregut malformations. Usually found in the thorax, it may be located in the retroperitoneum. We report one case of subdiaphragmatic pulmonary sequestration detected by prenatal ultrasound, and diagnosed at surgery after birth. This case illustrates the diagnostic and therapeutic(More)
