Measurement of urinary loss in elderly incontinent patients. A simple and accurate method.

A simple method which uses beam balance scales, a portable timer, a large plastic-backed absorbent pad, and tight fitting pants has been developed to measure urinary loss in incontinent patients. Complete collection of all the urine lost was achieved in 220 (94%) of 234 incontinent episodes in patients from three long-term-care wards. The attendant's subjective assessment of "wetness", as used in other methods, was shown to be an extremely crude indicator of the degree of incontinence since the weight-gain in pads judged subjectively as being "wet" was anything from 0.7 to 341 g and there was considerable overlap between the weights of pads judged to be "dry", "damp", or "wet". In 6 healthy volunteers the mean weight-gain per pad caused by perspiration was 1.2 g/2 h and the mean change due to evaporation/leakage, determined by means of pre-wetted pads, was 1.0 g.

Impact of environmental sanitation and crowding on infant mortality in rural Bangladesh.

In two villages of Bangladesh, 2471 infants born in 1976 and 1977 were followed up for a year to study the impact of environmental sanitation and crowding on their mortality. Neonatal and postneonatal mortality rates in the study cohort were 100 and 75 per 1000 live-births, respectively. Multiple logistic regression analysis was done to estimate the effects of the selected risk factors while controlling for some socioeconomic, demographic, and biological characteristics. Risk of postneonatal mortality (PNNM) in the households which did not use latrines was 3 X 12 times (p less than 0.01) higher than in those which did and 1.5 times (p less than 0.05) higher in the households with 10 or more persons than in smaller households. PNNM in the households which did not use tube-wells (hand-pump) water was higher, but not significantly so, than in those which used tube-well water for all purposes. Neonatal mortality was completely unrelated to the environmental factors investigated.

Color measurement as a means of quantifying surface biofouling.

Laboratory reactors fitted with removable ceramic porcelain growth surfaces were inoculated with a consortium of biofilm forming environmental isolates. A Minolta colorimeter CR-200 (Minolta Camera Co., Ltd, Ramsey, NJ) was used in conjunction with a specially designed adapter to evaluate the reflective color of the porcelain disks as biofilm accumulated on them. Areal viable cell counts were monitored over a period of eleven days in two separate experiments and direct color measurements of the untreated, microbially fouled test surfaces were collected. This colorimetric assay was both non-destructive and immediate. A strong linear relationship between log cell density and log color change was observed. The Pearson product moment correlation coefficient for all 45 observations combined was r = 0.95. Separate regression lines for each experiment were not significantly different (P = 0.19). When adjusted for time, the (partial) correlation coefficient between log cell density and log color change was r = 0.87, which suggests that the relationship between the two measures can not be explained by their mutual dependence on time. Reflective color measurement provided a rapid, non-destructive and quantitative measure of biofllm accumulation.

The toilet as a transmission vector of vancomycin-resistant enterococci.

An elderly woman, admitted to the intensive care unit of a large university teaching hospital, was found to be colonized with vancomycin-resistant enterococci leading to the temporary closure of the unit. She had acquired the organism nosocomially, most likely from an environmental source, which had been contaminated when the toilet of a former patient, also colonized with vancomycin-resistant enterococci, had become blocked and overflowed throughout his and the adjoining room. This is the first report of a hospital toilet as the transmission vector for vancomycin-resistant enterococci.

Who washes hands after using the bathroom?

Handwashing is one of the most important control measures for preventing the spread of bacteria. Although young children are taught the procedure through different types of behavior modification, its effect has not been measured in older children. We have documentation that adults and health care workers have a compliance rate of only 50% with this basic control measure. This article reports on the compliance rate, duration, and handwashing techniques used by middle and high school students after using the bathroom.

Hygiene in the home: relating bugs and behaviour.

Much infectious intestinal disease (IID) arises in the home environment. If programmes to prevent infection are to be effective it is essential to both identify the particular practices that risk disease transmission, and to understand the reasons for these practices. An in-depth, multidisciplinary study of carer and child hygiene in the domestic environment in the Wirral, UK, employed structured observation, surface swabbing for polio vaccine virus and enteric marker organisms, semi-structured interviews, projective interviews and focus group discussions. Observations revealed that child carers washed hands with soap after changing a dirty nappy on 42% of occasions, and that one in five toilet users did not wash hands with soap afterwards. Microbiological samples were taken from household surfaces at sites thought likely to be involved in the transfer of faecal material. 15% of bathroom samples showed contamination with polio vaccine virus. Nappy changing took place mainly in living rooms. Contact with living room surfaces and objects during nappy changing was frequent and evidence of faecal contamination was found in 12% of living room samples. Evidence of faecal contamination was also found in kitchens, again on surfaces thought likely to be involved in the transmission of faeces (taps and soap dispensers). Key factors motivating hygiene were the desire to give a good impression to others, protection of the child and aesthetics. In this setting, the particular risk practices to be addressed included washing hands with soap after stool and nappy contact and preventing the transfer of pathogenic organisms to the kitchen. The occasion of the birth of a child may be a privileged moment for the promotion of safer home hygiene practices. Using polio vaccine virus as an indicator of faecal contamination produces results that could be used in large-scale studies of household disease transmission. A better understanding of the household transmission of the agents of IID using multidisciplinary methods is needed if effective hygiene promotion programmes are to be designed.

The fake patient: a research experiment in a Ghanaian hospital.

The authors report on a research experiment involving the admission of one of them as a pseudo-patient in a rural Ghanaian hospital. The experiment was meant to assess the feasibility of carrying out unobtrusive participant observation in a hospital setting. Practical, methodological and ethical implications are discussed.

Epidemiological survey of swine cysticercosis in two rural communities of West-Cameroon.

To determine the prevalence of porcine cysticercosis, a survey was carried out in 27 villages belonging to two rural communities of West-Cameroon (Bafou and Bamendou). Between January and August, 2000, a total of 707 pigs were examined serologically and by tongue inspection. Serum samples were examined for circulating parasite antigen using a monoclonal antibody-based sandwich enzyme-linked-immunosorbent assay (Ag-ELISA) and for antibodies against cysticerci (Ab-ELISA). Seventy eight samples (11.0%) were found positive in the Ag-ELISA and 154 (21.8%) in the Ab-ELISA, while by tongue inspection on the same animals cysticerci were detected in 43 pigs (6.1%). Gibbs sampling using results of these three tests indicated that the estimated prevalence of porcine cysticercosis was 10.9%. Analysis of the Ag-ELISA results demonstrated that adult pigs showed a significantly higher seroprevalence (15%) than young ones (8.4%). There was no statistical difference in cysticercosis prevalence in pigs raised in households with or without a latrine. Animals that were reported to be usually confined were significantly less infected (9.9%) than free-roaming pigs (16.2%). Infection rates were significantly higher in pigs that had access to human faeces (13.8%) than those which did not have access (9.1%). This study has identified some community behavioural and environmental practices that should be modified to prevent continuous transmission of porcine cysticercosis.
