Hypertension screening in a salami factory: a worksite hypertension study.

The prevalence, awareness and control of hypertension are important epidemiological research topics worldwide. The screening of hypertension in a workplace has some special aspects. We have screened the employees in a Hungarian salami factory (Pick Salami Factory, Szeged, Hungary) for hypertensives. In a cross-sectional survey, the blood pressure (BP) was measured with an instrument meeting accepted measuring principles (BP-TRU BP) and a questionnaire was filled. In all, 1012 factory workers were screened (600 male and 412 female) and 25.7% of the workers proved to be hypertensives. Of these, 61.5% of the hypertensive employees were aware that their BP is high. Among the treated hypertensives, 21.9% were controlled. These results suggest that the efficacy of the management of hypertension in Hungary cannot be solely responsible for the high cardiovascular morbidity and mortality. The improvement of the management of hypertension should decrease the cardiovascular risk in the hypertensive population. The worksite screening and follow-up of hypertension seem to be logical health service solutions. This has been proven to be cost-effective.

Impaired accommodation of proximal stomach in patients with alcoholic liver cirrhosis.

BACKGROUND: Impaired gastric emptying has previously been detected by ultrasonography in cirrhotic patients, and the role of the type of meal has also been discussed. While these earlier studies dealt with the distal part of the stomach, the aim of our study was to examine the effects of three different types of meal on the proximal stomach in cirrhotic patients. METHODS: The proximal stomach was examined by ultrasonography in 15 healthy volunteers and in 21 alcoholic cirrhotic patients. The subjects received a liquid meal with a low calorie content and two different semisolid test meals with a low calorie content or high calorie and fat contents. The proximal gastric size was assessed by ultrasonography in a sagittal area and a frontal diameter. On the basis of assessment of the autonomic nervous function, the cirrhotic patients were divided into two groups: autonomic neuropathy positive and autonomic neuropathy negative. RESULTS: The postcibal gastric size immediately after ingestion of the liquid test meal was significantly lower in the cirrhotic patients than in the healthy controls. In the healthy volunteers, the measures of the proximal gastric size were significantly higher than in either group of cirrhotic patients at to, and at 10, 20 or 30 min after ingestion of a semisolid test meal with low calorie and fat contents. The proximal gastric sizes in the three groups of investigated subjects did not differ when the meal with high fat and calorie contents was tested. When the liquid meal was administered, the proximal gastric size was significantly lower in the cirrhotic patients with autonomic neuropathy. A significant intragroup difference was not observed when the semisolid meals were tested. CONCLUSIONS: This study reveals an impairment of the proximal stomach in alcoholic cirrhotic patients. The low calorie liquid meal distinguishes between the two groups of cirrhotic patients and healthy controls.

Brainstem auditory-evoked potential examinations in diabetic patients.

Brainstem auditory-evoked potential (BAEP) examinations were performed in 15 patients with long-standing type-1 diabetes mellitus (DM). Cardiovascular reflex tests were applied for assessment of autonomic neuropathy. The aim of our investigation was to compare the BAEP results of this patient group with controls and to look for a possible correlation between the alteration of the auditory brainstem function and the cardiovascular autonomic neuropathy. Analysis of the latencies (waves I, II, III and V) and the inter-peak latencies (waves I-III and I-V) of BAEPs revealed a significant difference between diabetics and healthy controls. The amplitudes of waves I, III and V were definitely lower in comparison with those of healthy controls. A positive correlation was observed between the overall autonomic score and the latencies (waves III and V) and inter-peak latencies (waves I-III and I-V). These data support the hypothesis that long-standing DM and diabetic neuropathy might be related as a cause of certain dysfunctions of the central auditory pathways.
