Forty-seven children, ages 1 to 14 years, with appendicular peritonitis were randomly divided into two groups: 27 were treated with the combination tobramycin-clindamycin and 20 with cephalothin followed by cephalexin. The overall rate of complications was 32%. Patients who had had their symptoms for less than 48 hours before being admitted to hospital had(More)
We followed 40 girls who had undergone antireflux surgery (the Politano-Leadbetter technique) at the mean age of 5.2 years until they reached a mean age of 9.5 years. Each girl was matched with a control. The pairs were matched for age at the onset of urinary tract infections and time of operation or selection, number as well as grade (1 to 3) of severity(More)
Thirty-two Escherichia coli strains from 30 children with pyelonephritis were examined for their haemagglutination patterns and O and K serotypes. 29 (91%) of the strains showed mannose-resistant haemagglutination (MRHA). By use of well-defined target cells, these MRHA+ strains could be shown to recognise human cells either in a P-specific manner(More)
Observations are reported from a series of 284 children, 68 boys and 216 girls, who had had one or more episodes of urinary tract infection (UTI) and had vesicoureteral reflux (VUR) of grade II, III or VI. In 6 of the boys and 43 of the girls the Politano-Leadbetter operation for correction of VUR was performed. Only in grade III or IV VUR was the cure(More)
196 episodes of urinary tract infection in children were analysed. 74 were classified as pyelonephritic (PN), 61 as cystitis (C), and 61 as asymptomatic bacteriuria (ABU) on the basis of three clinical signs (elevated temperature, erythrocyte sedimentation rate, and/or white blood cell count). The frequency of P-fimbriae was found high in PN (77%), and(More)
Serum concentrations of group I and II pepsinogens (PG I and PG II) were determined in 15 patients with chronic renal failure. Gastroduodenoscopy with biopsy and acid secretion tests were also performed. Five patients had histologically confirmed severe Brunner's gland hyperplasia manifesting as multiple polyps in the duodenal bulb. Five patients had a mild(More)
Multiple duodenal polyps were found by endoscopy in five out of 33 patients with chronic renal failure and in one of 300 controls. In the uraemic cases the polyps were caused by circumscribed nodular hyperplasia of Brunner's glands. One of these five patients later underwent surgery for duodenal obstruction caused by the polyps; the other patients were(More)
The mean concentration of free thyroxin (FT4) in serum, as determined by direct equilibrium dialysis, was decreased in patients with chronic renal failure (CRF) and increased in patients with various other nonthyroidal illnesses (NTI). The mean concentration of dialyzable free triiodothyronine (FT3) in serum was equally low in both groups of patients.(More)
