Lung function tests were performed in this study on 139 adults (mean age 36 years), as well as on 91 female persons between 16 and 18 years of age (the latter just starting on their professional careers), the lungs being healthy in each case in both groups. The findings were compared with the currently accepted reference value formulae after Quanjer et al., and Zapletal as well as further developed reference value formulae after Brändli et al., Most of the measurement data obtained by spirometry for the BGFA group of probands are between the two recommended reference values for adults with better coincidence with Brändli's predictions (exceptions being MMEF25-75 MEF 50 and MEF 25). In our studies we obtained higher values than the reference median values after Quanjer and Zapletal for IVC, FVC, FEV1 and PEF by 6-8% and 5-15%, respectively, whereas the values for adults differ from the predictions made by Brändli et al. by -4% to +5%. The flow data MMEF 75-25, MEF 50 and especially MEF 25 are set at too low levels (by 5-23%) by Zapletal's and Brändli's values. Comparatively, the values predicted by Quanjer et al. for the above mentioned flow-volume parameters (with the exception of MEF 75) are too high by 4% to 12%. There are also considerable differences in respect of the reference values for IGV to the tune of +15% in the BGFA group compared to Quanjer et al.; in the BAFAM group the values differ from those of Zapletal et al. by +17%. RV yields results in the BGFA group which are higher by 11% than according to Quanjer's formulae, whereas in the BAFAM group they are higher by 15% compared to Zapletal's predictions. In respect of Rt there are differences to the predictions by Rühle and Matthys by +16% (BGFA group) and +13% (BAFAM group), respectively. The BAFAM group differs from Zapletal's predictions by +11%. Looking at the reference limit values the overall impression is confirmed that the predictions after Quanjer et al. and mostly also those by Zapletal are too low in respect of the abovementioned lung function parameters (in the majority of cases not 5% of the examined probands, as expected, are below those levels, but only about 2%). Females, who had been underrepresented in the previous healthy proband groups, show larger deviations than males in respect of most of the parameters.(ABSTRACT TRUNCATED AT 400 WORDS)
In the animal zoo Dählhölzli Berne all ungulates are continuously monitored since 1984 (qualitatively and quantitatively) in the context of an epidemiological study on gastrointestinal strongyles. Fecal sampling occurs every two weeks in the "parasite risk group", every four to six weeks in the so called "non-risk group". Risk group-animals repeatedly show increased fecal egg counts, whereas among non-risk group-animals only ascarid eggs in Przewalski-horses and wild boars can become significant. The animals are treated (metaphylactically) only at a high egg production or at a steadily increasing egg production. A resulting slight but constant reinfection allows the build-up of an immunity, leading thereby to a decreased frequency of treatment. During the monitoring period (1984-1990) only four animals out of 80 post-mortem analysed animals had a diagnoses of an endoparasitoses as a cause of death.
Culex quinquefasciatus, which is sometimes the vector of Bancroft's filariasis, is a harmful mosquito, the immature stages of which live in collections of waste water resulting from human activity. Larval control, the most appropriate method, is at present carried out with chemical insecticides. But the toxicity of these compounds, together with phenomena of resistance, and the cost of substitute insecticides have turned research towards products of biological origin, and one of the most promising is a liquid concentrate of Bacillus sphaericus strain 2362. This was applied experimentally over an area of 200 hectares in a large city in the south of Cameroon, characterized by a short dry season during which mosquito density is at its highest. Spraying was carried out every three months for a year in a concentration of 10 g/m2 and its efficacy evaluated at the level of adult mosquitos through an indirect system of capture on human baits. The results of this study show, in essence, a reduction by 52.7% in the number of females captured in the overall study area treated, and that the impact of treatment is greater during the period of high mosquito density (55.1%) than in the low density period (40.7%). After analysis of the full set of results, the authors conclude that the pattern of rainfall, the conditions in which the insecticide is applied and reinvasions of mosquitos from untreated areas were the principal factors limiting the efficacy of this control campaign.(ABSTRACT TRUNCATED AT 250 WORDS)
The General Electric-Elscint system for telephone line transmission of rectillinear scans has been tested and with certain limitations found to be acceptable in terms of diagnostic accuracy for many scan procedures. The system tested had some logistic disadvantage requiring batch processing of the scans, and making quality control of the scans difficult with the one video data processor available at the reference centre.

The topic of article is a two-year trial of health service for doctors in the districts of Asker and Eidsvoll, under the auspices of the Akershus branch of the Norwegian Medical Association. The object of the trial was to develop a model for a health service for doctors. All doctors in the selected districts, except those covered by occupational health services, were invited to take part in the trial. Doctors recruited as doctors for colleagues, were given systematic tutoring and teaching throughout the trial period. The authors describe how the trial was organized and carried out, and summarize the practical experience gained so far. They also give a brief account of the continued efforts of the Akershus branch of the Norwegian Medical Association to develop a better health service for doctors.
Direct patient care has not fully benefited from a number of recent advances in modern technology. Many of the normal data collections tasks carried out by care providers are still done with manual, error-prone procedures. In addition, the ability to consolidate or represent patient data in a meaningful and timely fashion as required by managed care expectations is unavailable. The reported work attempts to address these problems with the application of new hand-held computing technology.

At the Ulm University Hospital 43 type-1-diabetes patients took part in a structured in-patient diabetes education program during a 12-day hospitalization period. 27 of the patients received an additional motivational support program which addressed psychological and social impediments related to the topics of the structured diabetes education program. 16 patients underwent the structured diabetes education program only. Motivational support aimed at reducing the specifically addressed sociopsychological barriers. Thus, the effects of the structured diabetes education program should be stabilized and an optimal outcome insured. All patients were asked to complete a questionnaire before, right after and 3 months after the program. Glycosylated hemoglobin (HbAlc) was evaluated before and 3 months after the program. Patients who underwent the motivational support program still felt 3 months after completion of the program that metabolic control was important, whereas patients without motivational support did not. Metabolic control--as indicated by measurement of glycosylated hemoglobin--could be maintained in the patient group with motivational support. Although their blood glucose levels had been in the normal range to start with. These encouraging results suggest implementation of a motivational support program into standard diabetes education programs for type-I-diabetes patients.
BACKGROUND: Nurses routinely "dangle" patients to evaluate and promote tolerance to changes in body position and to determine whether the level of activity should progress. Although dangling is a widespread nursing intervention, little research has been done on it, and little is known about how nurses dangle patients. OBJECTIVE: To describe dangling practices reported by critical care and acute care nurses. METHODS: A structured interview tool, developed for the study, was used to interview 51 experienced critical care and acute nurses from seven states about dangling practices. RESULTS: Most respondents said dangling was not routinely ordered and did not require a physician's order. The nurses described numerous strategies they used beforehand to promote tolerance to dangling, for example, premedicating for pain, and multiple interventions they used if patients did not seem to do well during dangling, for example, having patients take slow, deep breaths or move the feet and arms. Indicators of intolerance to dangling included marked changes in blood pressure, heart rate, and level of consciousness and patients' comments such as, "I can't stand it." Estimates of the duration of dangling varied widely, from 1 to 10 minutes; most respondents stated that duration varied "by feel" or depended on the patient's response. The most frequently mentioned personal rule about dangling was, "Get help if you're not sure how the patient will do." CONCLUSIONS: Nurses have developed numerous approaches to dangling acutely ill patients. These approaches should be described and tested to improve nursing practice and patient outcomes.

The Latino/a Research & Policy Center (LRPC), at the University of Colorado (UC) at Denver and Health Sciences Center built the Greater Denver Latino Cancer Prevention Network, a successful cancer prevention network, in 6 Denver metro area counties. The Network consisted of 23 Latino community-based organizations, health clinics, social service agencies, faith-based groups, and employee-based organizations; 2 migrant health clinics; and 14 scientific partners including the UC Comprehensive Cancer Center, the Colorado Department of Public Health and Environment, and the American Cancer Society. The Network focused on 5 significant cancers: breast, cervical, lung, colorectal, and prostate cancer. The Steering Committee initiated a review process for junior researchers that resulted in 5 NCI-funded pilot projects. Pilot projects were conducted with various Latino populations. The Network developed community education and health promotion projects including the bilingual outreach play The Cancer Monologues. The Network's partnership also started and held 2 annual health fairs, Dia de la Mujer Latina/Day of the Latina Woman, and annual health prevention summits. The Special Population Network (SPN) adapted and revised a clinical trials education outreach module that reached Network community partners. SPN partners recruited Latino/a students to cancer research through a6-week NCI training program held yearly at the UCHSC campus. The Network methodology of bringing together the Latino community with the scientific community increased the level of awareness of cancer in the Latino community and increased cancer research and the level of engagement of the scientific partners with the Latino community.

Since 1985, the French National Association ADICAP (Association for the promotion of computer use in Cytology and Anatomic Pathology) has been active in the creation a microscope workstation for developing a bank of digitized images to be used for diagnostic and educational purposes. In 1989 one of the authors (P. Dusserre) has created a first telepathology network using this workstation. Since then, 32 workstations have been set up in private and public Departments of Pathology. Two of them are located overseas, in the Martinique and Guadeloupe islands. In this paper, the authors describe this system, called Transpath, which is a multi-purpose and modulable workstation. 3-years experience and several accuracy tests have shown that the quality of transmitted images ensure a reliable diagnosis in more than 95% of cases. It has been decided to extend this service to other French overseas territories and to develop a group of experts. The images bank will also be developed and recorded on CD-ROM. The authors intend to participate in a future European project (PILOT project, i.e. Pathology International and Local Operational Telematics), with the purpose of establishing real intercommunication between European and other networks on a worldwide basis.
