ABSTRACT
INTRODUCTION: Allergic reactions caused by animals are a common and significant occupational health concern. In a large population-based study on occupational asthma in Europe, farming has been among the occupations with the highest risk. OBJECTIVES: Characteristics of cattle-allergic farmers are described in a retrospective observational design. METHODS: The study covers farmers from all regions of Germany which were reported to the Agricultural Institutions for Statutory Accident Insurance and Prevention (Landwirtschaftliche Berufsgenossenschaften, LBGs) between 1990 (January) and 2002 (December) with a suspected occupational cattle-allergic airways disease. For these farmers, the following parameters were considered: age, gender, onset of airways symptoms related to contact with cattle, begin of employment disability, total and specific Immunoglobulin E (IgE) against cattle allergens, and results of lung function measurements. RESULTS: A total of 513 patients (age 14-74, mean 40.7 years; 45.6% women, 54.4% men) had been reported for a suspected occupational cattle-allergic airways disease. Of these patients 24.8% showed cattle-related symptoms of asthma, 11.7% of rhinitis, and 60% of both asthma and rhinitis, while only 34.5% of all reported patients showed an airways obstruction in the first documented lung function test. A total of 62.5% out of the group of patients with an officially recognized occupational disease (42.1%, n=216) have an initial employment disability with a rating of 20% or above. CONCLUSIONS: Our results underline the high public health relevance of cattle allergy in farmers, especially in the light of the large number of young patients. Considering the known difficulties in diagnosing cattle allergy due to the number of false negative test results, we are convinced that its relevance is even higher than the number of reported cases suggests. The high rate of initial employment disability among the affected patients underlines the need for improved preventive measures.

AIMS: To analyse the effect of diabetes (DM) on diastolic function in hypertensive patients. METHODS: 439 hypertensive patients were selected for participation in this study. All participants had an echocardiographic evaluation of systolic and diastolic function. The overall degree of diastolic function and specific parameters (e.g. E/Ea ratio) were analysed. RESULTS: We divided the cohort (63+/-10 years) into those with diabetes mellitus (DM(+), n=124) and without diabetes mellitus (DM(-), n=315). The prevalence of normal diastolic function was lower in DM(+) than DM(-) (19.4% vs. 30.8%); mild (65.3% vs. 60.0%) and moderate/ severe diastolic dysfunction were more frequent in DM(+) (15.3% vs. 9.2%, p=0.022). The E/Ea ratio, an estimate of left ventricular end-diastolic pressure, was significantly higher in DM(+) (12.3+/-4.4) as compared to DM(-) (10.8+/-3.6, p<0.001). Sex-specific analysis revealed that the effect of DM on diastolic function was mainly limited to the male subgroup. Multivariate logistic regression analysis showed that diabetes affected diastolic function in males independent of blood pressure, left ventricular mass index, concomitant medication and prevalence of coronary artery disease. CONCLUSION: Diabetes negatively affects diastolic function in patients with arterial hypertension. This effect is mainly confined to the male subgroup.

For the identification of susceptibility loci in complex diseases the choice of the target phenotype is very important. We compared results of genome-wide searches for linkage or for association related to three phenotypes for alcohol use disorder. These are a behavioral score BQ, based on a 12-item questionnaire about drinking behavior and the subject's report of drinking-related health problems, and ERP pattern and ERP magnitude, both derived from the eyes closed resting ERP measures to quantify brain activity. Overall, we were able to identify 11 candidate regions for linkage. Only two regions were found to be related to both BQ and one of the ERP phenotypes. The genome-wide search for association using single-nucleotide polymorphisms did not yield interesting leads.
