Symptomatic urinary infection in childhood: presentation during a four-year study in general practice and significance and outcome at seven years.

Thirty-eight children (12 boys and 26 girls) with symptomatic urinary infection have been studied in general practice. Patients were collected over a four-year period and we report an incidence of urinary infection according to Kass's criterion of 7.7 per 1,000 girls at risk per year and 3.8 per 1,000 boys at risk per year. Eighty-four per cent of the children had symptoms which suggested an origin in the genitourinary tract. Proteus infection was found in five of the boys and only one of the girls. At the end of the four-year study period follow-up had taken place over a mean period of 25 months and recurrent infection had been demonstrated in four boys and 12 girls. All the children had an excretion urogram and two children, both girls, were found to have pyelonephritic scarring. Twelve children with recurrent infection were investigated for vesicoureteric reflux, which was found only in the two children with scarring. At seven years 31 of the children remained in the practice and, with a mean follow-up of 42 months, no significant alteration in the figures for recurrent infection was demonstrated. Guidelines are suggested for the management of childhood urinary infection in general practice.

Galactosaemia: estimated live birth incidence in New Zealand.

194 cord blood samples were studied in both a fluorimetric assay and an electrophoresis method for Gal-1-PUT. From this the expected live birth incidence was 1:37000. The New Zealand neonatal screening programme has detected 5 cases in 223326 live births--an apparent incidence of 1:44600. The Beutler testing of dried blood spots collected on filter paper cards is a satisfactory method of detecting galactosaemia in the neonate.

Familial leukaemia: a study of 909 families.

A family survey was conducted among 909 patients with leukaemia of all types, with the purpose of establishing the incidence of further cases of leukaemia among relatives. Among a total of 41,807 relatives 8,349 were deceased, and the cause of death was objectively confirmed in 5,011. 72 patients had one or more relatives with leukaemia. First degree relatives with leukaemia were much more frequent in families of patients with chronic lymphocytic than in those of patients with chronic granulocytic leukaemia. The incidence of leukaemia among first degree relatives was established to be 2.8-3.0 times, among more distant relatives about 2.3 times, and overall about 2.5 times that expected. This excess is of the order of that observed in relatives of patients with certain solid tumors. Genetic factors may have accounted for much of the excess incidence in chronic lymphocytic and acute leukaemia, but there was little evidence for a genetic background in chronic granulocytic leukaemia. With the possible exception of one family with multiple cases, a simple Mendelian mechanism did not appear to be involved in the leukaemia families investigated. It appeared more likely that a polygenic mechanism led to a heightened susceptibility to the disease in these families.
