The Montreal Adoption Survey was conducted as a cross-sectional epidemiologic study of cardiovascular risk factors in French Canadian families. Analysis included blood pressure readings of 756 adopted and 445 natural children as well as 1176 parents. A genetic model was applied to the analysis of our data. Interindividual variability of blood pressure was(More)
Seventy-seven children with chronic renal failure were examined at one hospital in the province of Quebec between 1970 and 1975; this represents an incidence of 2.5 per million population per year. The entities responsible for chronic renal failure were urinary tract malformation (in 36%), chronic glomerulonephritis (in 22%), congenital renal parenchymal(More)
Tests of homogeneity of means, variances and correlations for systolic blood pressure (BP), diastolic BP and weight among subdivisions of a smple of adoptive families are presented. The means and variances of either type of BP, but not weight, were not significantly heterogeneous among families grouped according to the number of parents and children,(More)
The long-term damaging potential of remnant nephron hyperperfusion was investigated in patients who had undergone unilateral nephrectomy in childhood. 27 such patients were examined after a mean of 23.3 years postnephrectomy. The average creatinine clearance was 83.9 +/- 16.5 ml/min/1.73 m2 or 74.3% of that in healthy controls with two kidneys; it was a(More)
The purpose of the present study was to assess the effect of intelligence, schooling, psychomotor, emotional, and social status on renal graft survival in children. Sixty-two cadaver renal transplant recipients were evaluated retrospectively and the influence of sex, age, weight, and the use of cyclosporin A (CyA) on the success rate of the graft from 1 to(More)
An analysis of the familial aggregation of blood pressure (BP) was conducted to provide estimates of the role of genes and household environment in determining the phenotypic resemblance between biologically related family members. The biological model used for this analysis parameterizes the correlations between family members into the contributions of(More)
This study presents an analysis of the role of genetic and household environment in explaining the familial aggregation of height (HT), weight (WT), and body mass indices (WT/HT1.2 and WT/HT2.0). The biologic model used for the analysis partitions the covariances between family members into the contributions of genetic and environmental variability shared(More)
Blood pressure was measured in each member of 398 French-Canadian families with at least one adopted child of the same ethnic origin. Measurements were made at home by a nurse, usually with the subject seated. One comparison per family between parents and randomly chosen index children was made, using age- and sex-adjusted scores. The correlation in blood(More)
In 1981, we reported the outcome of 25 children with FSG after a follow-up of 10 years. In 1991, all the living patients were reevaluated. Ten patients are now in sustained remission. Four patients still present heavy proteinuria with a normal glomerular filtration rate, four required dialysis and seven patients have died. The renal survival curve has(More)
