OBJECTIVES Since it is still controversial whether-low-to moderate long-term lead exposure below current threshold values causes neurobehavioural deficits in adults, we investigated executive functions of the prefrontal cortex, attention, and visuospatial and visuomotor functioning in lead-exposed subjects. METHODS Forty-seven lead-exposed subjects with a(More)
OBJECTIVES Many antineoplastic drugs were found to have carcinogenic, mutagenic and teratogenic potential. The aim of this study was to carry out cytogenetic and internal dose monitoring of hospital pharmacy personnel regularly involved in the preparation of cytostatic agents, in order to test possible cytostatics-induced genotoxic effects due to(More)
BACKGROUND Mercury poisoning presents a variety of clinical pictures depending on chemical structure, the route of exposure, amount absorbed and individual factors. Thus, an injection of metallic mercury can be considered relatively harmless in contrast to inhalation of mercury vapor. Injection of elemental mercury is rare, and a total of only 78 cases have(More)
HISTORY AND ADMISSION FINDINGS 3 years ago, a 63-year-old man underwent laparotomia due to clinical signs of acute abdominal pain. The anemia was treated with erythrocyte concentrates. Several weeks before the current admission to our outpatient department, the patient was again hospitalized because of acute abdominal pain and anemia. The patient was then(More)
HYPOTHESIS Does occupational exposure to solvents in combination with alcohol intake give rise to acquired color vision defects? METHOD A total of 138 individuals exposed to solvents (toluene, xylene, trichloroethylene, tetrachloroethylene) were examined using Lanthony's D-15 test and compared with 100 nonexposed controls. The extent of color vision loss(More)
HISTORY AND REASON FOR ADMISSION A 44-year-old man had anginal-like complaints. He was convinced that cardiac problems had been caused by electromagnetic fields. INVESTIGATIONS Apart from hypertension and hyperlipidaemia there were no other significant findings. ECG, ergometry Holter-ECG were normal. EXPERIMENT We tried to verify with a double-blind(More)
It was our aim to study whether chronic exposure to vanadium reduces cognitive abilities. We investigated effects on attention, visuospatial and visuomotor functioning, reaction time, short-term memory, and prefrontal functioning. Forty-nine vanadium exposed subjects with a mean vanadium level in urine (VanU) of 14.4 micro/L and 49 controls (VanU: 0.8(More)
