Evaluation of products for treating babies' napkins.

A test is described for assessing the sanitizing effect of napkin treatment products on naturally urine-wetted and faecally-contaminated napkins. This test defines in-use conditions which closely resemble typical domestic situations. One napkin treatment product ('Napisan'), tested at two different concentrations and with challenges of different numbers of babies' napkins, performed satisfactorily under the conditions used.

Protective isolation and antimicrobial decontamination in patients with high susceptibility to infection. A prospective cooperative study of gnotobiotic care in acute leukaemia patients. III: The quality of isolation and decontamination.

In a cooperative study, the quality of protective isolation and of antibiotic decontamination of the digestive tract was studied in patients with acute leukaemia by (bio)-typing of Enterobacteriaceae species, Pseudomonas aeruginosa and Staphylococcus aureus isolated from oral washings and faecal samples. These samples were collected before and during treatment of 82 patients who were either isolated and decontaminated for which latter purposes a combination of neomycin, polymyxin, bacitracin and nystatin was used (group A); isolated without decontamination (Group B) or treated on the ward without decontamination (Group C). The results indicated that protective isolation had only been completely successful during the entire (remission induction) treatment period in one of the 32 patients in Group B. In Group A patients, who underwent antibiotic decontamination in addition, successful isolation was achieved in 57% of 28 patients. Successful antibiotic decontamination of the digestive tract for the entire treatment period as far as all potentially pathogenic species are concerned, was realized in 4 (14%) of the 28 patients of Group A. Bacteriologically confirmed infections occurred in 50% of Group A patients, in 59% Group B patients and in 64% of Group C patients. It is concluded that the quality of isolation had in general been insufficient but that it was improved by oral nonabsorbable antibiotics and, furthermore, that the antibiotic decontamination procedure also requires improvement.

Plastic isolators for treatment of acute leukaemia patients under "germ-free" conditions.

A gnotobiotic isolation system based on those developed in veterinary research has been constructed for hospital use. Fifteen patients with leukaemia and neutropenia spent a total of 110 weeks in plastic isolators, and none acquired any infection. Endogenous flora was effectively suppressed by topical antiseptics and gastrointestinal decontamination effected with nonabsorbable antibiotics. The isolator system was acceptable to patients and staff and much cheaper than the use of sterile rooms. Other advantages of the system are portability, easy storage, and use on ordinary open wards without prejudice to the microbiological protection afforded. It is as yet uncertain whether protective environments of this type will substantially improve the outcome of treatment for the acute leukaemias.

Indications for systemic antibiotic prophylaxis in neutropenic patients.

Four patients with malignant blood disease and neutropenia developed apparently localized infective lesions of the skin or conjunctiva from which Pseudomonas aeruginosa was cultured. In spite of appropriate local antimicrobial treatment all patients developed pseudomonas septicaemia within a short period and three died. It is argued that the isolation of pseudomonads from apparently localized lesions in patients with compromised antibacterial defences is an indication for systemic antibiotic therapy.
