Prosthetic hip-joint infection associated with a penicillin-tolerant group B streptococcus.

We report a case of prosthetic hip-joint infection with Streptococcus agalactiae (Lancefield group B streptococcus). The infection recurred after 3 months' treatment with amoxycillin. On further investigation, the isolate was found to be amoxycillin-tolerant. Addition of gentamicin abolished tolerance in vitro and the patient has remained asymptomatic since receiving a 10-day course of amoxycillin and gentamicin followed by amoxycillin alone.

The pharmacokinetics of cefuroxime axetil in the sick elderly patient.

The pharmacokinetics of cefuroxime axetil (RS3 formulation) were studied in 20 elderly patients following admission for lower respiratory or urinary tract infection. The mean age was 83.9 years. A 12-hourly dose of 250 mg was given for five days. The mean time to attain maximum serum concentration was 3.2 h with a mean peak concentration of 8.5 mg/l. The mean serum elimination half-life was 3.5 h and the AUC0-infinity 60.4 mg/h.l. There was no accumulation of the drug in the patients studied after five days treatment. The data suggest that the standard dosage regimen is adequate in the sick elderly patient.

Octadeca-9,11-dienoic acid in cervical intraepithelial neoplasia: a colposcopic study.

488 women were studied to evaluate the use of the molar ratio (%MR) of octadeca-9,11-dienoic acid (18:2(9, 11] to linoleic acid (18:2(9, 12] as a new screening method for cervical cancer and pre-cancer. A combination of Papanicolaou cytology, colposcopy and %MR 18:2(9, 11)/18:2(9, 12) were employed. 86 women (17.6%) were found to have histologically proven cervical intraepithelial neoplasia (CIN). The %MR was obtained in 452 cases (92%). There was no significant difference in %MR in cervical cell scrapes from women with or without CIN. The %MR of cervical scrapes in some women with anaerobic vaginosis was significantly elevated suggesting bacterial generation of 18:2(9, 11). The %MR of 18:2(9, 11)/18:2(9, 12) is unsuitable for the diagnosis of cervical intraepithelial neoplasia.
