[State of the nervous system of workers engaged in painting with bituminous lacquers].

The neurological and electroencephalographic examinations involved a group of 82 workers dealing with the protection of railway carriage assemblies against corrosion. For anamnesis "The Höck and Hess ailments questionnaire" was used to evaluate the neurotic syndrome. The results have been compared in varnishing workers under better and worse toxicological conditions. The evaluation of the varnishing workers' nervous system did not reveal any specific clinical picture. More frequent neurotic ailments and EEG deviations in those working under worse toxicological conditions may be indicative of enhanced neurotoxic effects of organic solvents, used for lacquers dilution, upon the brain disfunction.

Psychologic investigation in the estimation of the effects of hypotensive therapy in hypertensive patients working in the railway and highway traffic security.

Sixty four hypertensive patients working in railway and highway traffic security (engine operators, drivers, switchmen, etc.) were studied clinically and paraclinically and were also submitted to psychologic tests since the characteristics of their work requires a normal psychophysical state. The patients investigated, mostly males (93%), mean age 45.2 years, had essential arterial hypertension (AH) stages I (36 patients) and II (28 patients). After 3-4 days of low salt diet, therapy with propranolol (8 to 360 mg/day) and diuretics was started in most of the patients. In 8 patients with AH stage II, hydralazine (50-100 mg/days) was added to the treatment. The psychologic tests used were: the pencil-paper test "Labyrinth", "Barrage" and "A.D. Praga" and a motor test "Piorkowsky" used 2 times, i.e., before and after treatment. After 15 days of treatment the blood pressure values decreased: systolic from a mean value of 155 +/- 25 mmHg to 136 +/- 81 mmHg; diastolic from 102 + 18 mmHg to 84 +/- 11 mmHg. The marks for the psychologic test were: very poor, poor, medium, good, very good. The post-therapeutic changes obtained were noted in percentages. Improvements obtained: for the "Praga" test in 54% of the patients, for the "Barrage" in 44% of the patients and for the "Labyrinth" in 66% of the patients. Improvements for the first "Piorkowsky" test (slow rate stimuli) were obtained in 54% of the patients and for the second (faster rate stimuli) in 69%. No decrease of psychologic performance was observed in any of the patients. Therefore the psychologic tests used may contribute to the follow-up of the effectiveness and of the side effects of modern hypotensive therapy especially in patients working in traffic security in whom the psychophysical state should be at its best.
