Knowledge of Chlamydia trachomatis genital infection and its consequences in people attending a genitourinary medicine clinic.

Objectives: To assess knowledge of Chlamydia trachomatis infections, with a comparison of knowledge of Neisseria gonorrhoeae infections.

Methods: A cross sectional survey, by self completed questionnaire, of 200 subjects attending a genitourinary outpatient clinic.

Results: The response rate was 82% (90 male and 73 female).

Antimicrobial management of presumed microbial keratitis: guidelines for treatment of central and peripheral ulcers.

Aims: To determine the quantitative relation between the major risk factors for microbial keratitis of previous ocular surface disease and contact lens wear and central and peripheral infiltration, often associated with ulceration, in order to establish a rational chemotherapeutic management algorithm.

Methods: Data from 55 patients were collected over a 10 month period. All cases of presumed microbial keratitis where corneal scrapes had been subjected to microbiological examination were included.

Microbial contamination of cases used for storing contact lenses.

A survey of the hygienic practices of 178 contact lens wearers in west central Scotland was conducted along with assessment of microbial contamination of their lens storage cases. Multivariate analysis indicated that in some subgroups of lens wearers, the method of disinfection used, the use of unmodified tap water and the age of the lens, were significantly associated with microbial contamination of storage cases. In addition, statistical analysis suggested that features other than those commonly considered as important in contact lens hygiene, and therefore included in this study, may be more significant predictors of contamination of cases.

Microbial contamination of contact lens cases in the west of Scotland.

A cross-sectional study of 178 asymptomatic contact lens wearers attending 10 contact lens practices in the west of Scotland was conducted over a 4 month period. The aims of the study were to identify specific microbial contaminants in lens cases, to determine the rate of contamination of such containers and to assess the value of the steps involved in different lens care regimens in the prevention of case contamination. Microbial contamination affected 53% of lens cases.
