Amoxycillin and co-trimoxazole in presumed viral respiratory infections of childhood: placebo-controlled trial.

A double-blind randomized controlled trial of amoxycillin, co-trimoxazole, and placebo was conducted on 197 children presenting with presumed viral respiratory infections. Routine throat swabs were taken to exclude streptococcal diseases. The three disease categories studied--nasopharyngitis, pharyngotonsillitis, and bronchitis (including laryngotracheobronchitis)--showed a generally similar pattern of resolution irrespective of treatment. Nevertheless, seven out of 66 children receiving placebo were withdrawn from the trial with unremitting symptoms or complications thought to require antimicrobial treatment. Only two of 56 children receiving amoxycillin and none of 75 receiving co-trimoxazole were withdrawn. Three other children receiving amoxycillin and three receiving placebo were seen during the trial but further treatment was not thought to be necessary. Thus the return consultation rate in children receiving placebo therapy was 15% compared with 4% for those receiving antimicrobial treatment. Antimicrobial treatment was associated with less nasal discharge on the eighth day of treatment. Placebo treatment allowed an earlier return to normal activity. There was a high incidence of possible side effects on all regimens including placebo. It is concluded that the benefits of antimicrobial treatment in presumed viral respiratory infections are marginal, and they should not be routinely prescribed for these conditions.

Treatment of urinary-tract infection with a single dose of amoxycillin.

31 patients with a urinary infection were treated with a single oral dose (3 g for adults and 100 mg/kg for children) of amoxycillin; 23 (74%) were cured. 20 women and 26 children were then randomly allocated to either a single dose of amoxycillin of a 5- to 7-day conventional course of the same antibiotic. The results of both treatment regimens were comparable. Single-dose therapy for the treatment of urinary-tract infections was simple, effective and well tolerated. Patients preferred taking their treatment in this manner. Failure of single-dose therapy to eradicate bacteriuria may indicate which patients require subsequent investigations of their urinary tract.

Neonatal bacteriuria: a prospective study in 1,460 infants.

In a prospective study of 1,460 virtually consecutive neonates 14 (1%) were found to have bacteriuria, established by bladder puncture. Eleven were boys and three girls. Five of the infants with bacteriuria had symptoms suggestive of infection and were treated with antibiotics. The remaining nine were asymptomatic and remained so during a period of observation-five cleared their urine of bacteria without treatment, and four received antibiotics. Only one infant with bacteriuria had bacteraemia. Six infants had more than 10 white blood cells per mm(3) in the bladder puncture urine and three had proteinuria. The blood urea was slightly raised in only two of the infants. The intravenous pyelogram was normal in all infants with bacteriuria but eight had slight or moderate vesicoureteric reflux when examined by micturating cystourethrography.

Transient asymptomatic bacteriuria in infancy.

Spontaneous clearing of bacteriuria occurred in three infants during the neonatal and early infancy period. In all cases, the presence of bacteria was confirmed by bladder puncture, no signs of clinical infection were present, and no treatment was given. The same host defence mechanisms as exist in adults were probably responsible for this phenomenon.

Pituitary gigantism in a 31 month old girl: endocrine studies and successful response to hypophysectomy.

A case of pituitary gigantism occurring in a 31 month old female child is reported. Growth records indicate that the disorder began early in the second yr of life. Apart from her size and history of excessive sweating, there were no characteristic clinical features of endocrinopathy. Elevated and autonomous secretion of GH (60-109 microgram/l) and prolactin were corrected by the removal of an eosinophilic pituitary adenoma. In the subsequent 6 yr, despite the presence of immunoreactive GH (4.6-17.3 microgram/l), plasma somatomedin was subnormal and the patient showed growth failure which responded normally to exogenous GH therapy. This case, which appears to be the youngest example of verified pituitary gigantism on record, illustrates that a successful outcome can be achieved by surgical ablative therapy.
