[The general aspects of the epidemiology of hospital infections--the measures for prevention and control].

The author analyzes the 3 important factors of in-hospital infections--the source of infection, route of transmission and the receptive organism, with details regarding the measures of prevention and control. Emphasis is laid on the role of the hospital personal which have an effective contribution in the prevention of these diseases, namely: a) strict application of hygiene measures (hospitalization conditions, microclimate, food, water supply, removal of wastes and residues, sterilization, disinfection, cleaning, etc.); b) choice of procedures of investigations and therapy with minimum risk of infection, application of asepsis and antisepsis techniques, the judicious use of antibiotics; c) accurate, prompt evaluation of the infectious potential and receptivity of the patients; d) clinical surveillance of the patients and health of the personal; e) corresponding professional education of the entire personal of the hospital. Further indications are given regarding correct performance of disinfection and sterilization and the substances used.

[Surgical sepsis: myths and realities].

The authors review the modern knowledge of sepsis, asepsis and antisepsis in surgery; they underline some surgeon's customary attitudes and convictions no more scientifically significant today.

An aseptic method to loosen tight, relaxing sutures.

Relaxing sutures are placed to prevent wound dehiscence. These sutures sometimes become too tight, and local pain or edema ensues. An aseptic loosening of the relaxing sutures was devised and healing of the wound was accelerated.

Bacterial contamination potential of sterile, prefilled humidifiers and nebulizer reservoirs.

Contaminated respiratory therapy equipment may be responsible for the spread of pathogens to hospital patients. This study focused on the potential for contamination of prefilled, sterile, disposable water and saline systems for humidification and nebulization. Gas and liquid samples from 48 prepacked oxygen humidifier/cannula and 26 prepacked nebulization setups were taken at the initial application of devices and at 8, 24, 48, and 72 hour intervals, totaling 386 cultures. All samples from the humidifier units were found to be pathogen-free for up to 3 days. A total of six or 3.84% of the nebulizer samples showed contamination with Enterobacter cloacae after 8 to 24 hours of operation. It was concluded that the potential for contamination of the humidifiers is low for up to 72 hours, but the nebulizer units should be changed after 24 hours even though their contamination rate is markedly lower than that of conventional nondisposable units.

[Research in hospital health at the Institute of General and Community Health of the Greifswald Ernst-Moritz-Arndt University].

With a retrospect of the historical development of hygiene in Greifswald the essential tasks of research in hospital hygiene especially during the last two decades are shown. The problems of hospital hygiene have been treated already before the establishment of the Institute of Hygiene of the University. Friedrich Loeffler, who as a young researcher had already treated the problems of disinfection and antisepsis, has founded the systematic hygienic-microbiological-virological working direction in Greifswald. Out of this in the following years with different essential tasks and devotion the hospital hygiene has developed in Greifswald. During the process of differentiation and forming of the department and later the Institute of General and Communal Hygiene was the hospital hygiene an essential task of research work. As peculiarity to this a close research co-operation has been developed with the territorial Institute of Hygiene of District Hygiene Inspection Rostock.

[Various hygienic problems in ambulatory dental surgery].

Oral surgical interventions on an outpatient basis are attended by considerable hygienic hazards. The main reasons of this, which are in part subjective and in part objective, are presented. Some typical examples show that at least minimal hygienic requirements may be met by the physician and by the patient also under apparently unfavourable conditions. An optimal solution must be aimed at, but this requires certain prerequisites as to equipment and premises. In any case, it must be called for in planning and establishing greater stomatological services that sould be preferred for this reason to single practices also from the viewpoint of hygiene. Consequently, the propagation of hospitalism and infections caused by pathogenic organisms may be controlled by strict hygienic measures also in our specialty.

Practical methods for the microbial validation of sterilizing-grade filters used in aseptic processing.

Microbial challenge test methods to validate sterilizing-grade filters were developed to facilitate the use of parenteral drug products as liquid vehicles. Scaled-down filtration systems were developed in response to processing parameters, e.g., flow rates, pressures, duration, and temperature, provided by customers. Accordingly, 47 mm disc filter holders were chosen to minimize the volume of product necessary for each test. A peristaltic pump was used to produce positive pressure within the test system, and a 47mm filter sampling manifold was used to assay the entire filtrate. The resultant system was able to accommodate a variety of flow rates while maintaining the viability of the retention test microorganism, Pseudomonas diminuta (ATCC Number 19146). Experiments were conducted by challenging sterilizing-grade (0.22 micron) and 0.45 micron polyvinylidene difluoride (PVDF) (Durapore) filter discs under simulated processing conditions with P. diminuta resuspended in the pharmaceutical products. The challenge concentration was at least 10(7) colony forming units per cm2 of filter area. The 0.22 micron filters were shown to be retentive in all cases, while the 0.45 micron membranes exhibited some degree of bacterial passage as expected. The results of these experiments were communicated to the customers for inclusion in their process validation documentation.
