[Alumni of medical sciences and their life satisfaction].

OBJECTIVES AND METHODS: Medical doctors are especially burdened with psychological and social aspects of their occupation. These circumstances may lead to low life satisfaction and substance abusing behaviour and burn out symptoms are probable. In this paper we investigate, if alumni of medical sciences show lower life satisfaction compared to their peers. If so, we want to know, which factors influence this result. This survey is based on n = 671 alumni of medicine in seven German universities. RESULTS: The life satisfaction of alumni differs significantly from the peer sample. Outstanding are the highly significant and powerful differences to the scale "leisure". It was evident by an iterative regression that the variables "extreme input at work", "instrumentality/masculinity", "effort-reward imbalance", "expressivity/femininity" as well as "career self-efficacy-expectation", clarify 43 % of the variance in the group of alumni working by the time of enquiry. CONCLUSIONS: The results point out, that already alumni of medical science are in the "circle of burn-out". Their life satisfaction is more affected, if the workload is perceived high and the perceived benefits are low. Individual as well as external aspects influence life satisfaction and can be a starting-point for prevention.

Knowledge and attitudes towards preimplantation genetic diagnosis in Germany.

BACKGROUND: Preimplantation genetic diagnosis (PGD) is a technique which is often related to emotional debates because of its ethical and social implications. Worldwide there are different forms of legislation; Germany constitutes an interesting case because of the historical background concerning eugenics and dealing with handicapped persons at the time of national socialism. PGD is currently not legal but there are still polarized positions and legalization remains an issue. Studies about the attitudes of the general population towards PGD are rare. METHODS: Data were collected in a representative survey carried out in November 2003. Subjects were 2110 persons in Germany aged 18-50 years. RESULTS AND CONCLUSIONS: Respondents had little knowledge about PGD. There were incorrect assumptions about the diagnostic possibilities and a lack of basic genetic knowledge. A tendency towards a general acceptance of PGD for medical indications was found. Non-medical indications such as sex selection were generally not accepted. It could be observed that respondents who already had a notion about PGD overestimated the diagnostic possibilities and would eventually use PGD in the future more than respondents who had never heard about PGD before.

[Investigation and evaluation of fumonisin contamination of native and imported cereals].

Cereal varieties cultivated in Germany, such as wheat, rye, grain-maize, barley, and oats were analyzed for fumonisins, including also imported maize from Argentina. In a total of 410 wheat samples and 140 rye samples of two harvesting years (1993, 1994) and in random samples of barley and oats no fumonisins were detected at all. In german grain-maize of 1993, only low fumonisin contents (17-33 ng/g) were detected occasionally. Some grainmaize samples of the 1994 harvest contained significantly higher fumonisin amounts, partly up to the mg/kg-range, which obviously is due to the extremely high temperatures during summer. In some samples of variety tests of the country the fumonisin B1 content amounted up to 4828 ng/g and the total fumonisin content (FB1-FB3) up to 7132 ng/g respectively. In 1994 a total of 317 native grain-maize samples was tested, of it 109 samples of German cultivation and 208 samples from variety tests of different federal states. Maize samples from Baden-Württemberg, which are representative to the maize harvest of this state, had a fumonisin contamination of 14%, the mean value of the contaminated samples amounting to 206 ng/g. Of the imported maize from Argentina, all the investigated 21 samples had a fumonisin content (FB1-FB3) of 14-1106 ng/g, the mean fumonisin content amounting to 175 ng/g.

[Determination of the activities of lipase, lipoxygenase and peroxidase in native and extruded cereal brans].

To avoid fat deterioration in grain products during storage the cereal inherent enzymes lipase, lipoxygenase and peroxidase have to be inactivated. Known methods for the determination of the enzymes activity are tested and their applicability evaluated. Own optimized methods are presented. In laboratory and semiindustrial extrusion tests (laboratory single screw extruder, twin screw extruder, short screw extruder) the degree of enzyme inactivation of wheat bran, rye and maize bran, and oat bran is determined in dependence on the extrusion parameters. The enzymes mentioned already had been inactivated at mild extrusion conditions (temperature < 120 degrees C, moisture 20%, low mechanical stress). Only in brans of high fat content (10-14%) or high moisture (> 25%) minor residual activities of peroxidase and lipase were observed.

[Rheumatic fever. Its current status based on 4 cases].

We report on 4 patients with rheumatic fever hospitalized and investigated in our clinics within a 12 month period between 1990 and 1991. In each case a clinically non-severe sore throat preceded the outbreak of rheumatic fever. In three cases diagnosis was according to the revised Jones criteria. Polyarthritis was the only major symptom in these cases. One patient suffered from monarthritis. Minor symptoms were fever, arthralgia, elevated blood sedimentation rates and elevated values for CRP and for antistreptolysin O. The joint symptoms were treated with nonsteroidal drugs and subsided. One of the patients had a recurrence 9 months after the first attack even though correct secondary prophylaxis with a 4-weekly intramuscular regimen of 1.2 million units of benzathine penicillin was carried out. We discuss some epidemiological aspects and diagnostic difficulties resulting from a changing clinical pattern of the disease, and emphasize the need for streptococcal sore throat treatment and continuous secondary prophylaxis to prevent recurrences.
