Sodium nitroprusside (SNP) and hydroxocobalamin (HC) - in molar ratios of 1:4, 1:5, and 1:8, respectively - were infused simultaneously during 4 h into two veins of separate ears of conscious rabbits. Controls received HC only. Sodium thiosulphate (ST) was infused with SNP at molar ratios of 1:4, 1:5, and 1:10. The observation period was 48 h. With the(More)
Congenital intrapericardial teratoma is a rare, usually benign tumour frequently associated with massive pericardial effusion, cardiac compression, and severe cardiorespiratory distress shortly after birth. Surgical removal is not only curative but also potentially lifesaving because these lesions often become fatal if not promptly excised. We present a(More)
The subacute development of Marchiafava-Bignami disease (MBD) is reported in a 60-year-old patient from Southern Germany with a history of chronic alcoholism and severe malnutrition. Computed tomography scans showed progressive white matter destruction over a period of 8 months, ranging from diffuse hypodensities to well-delineated, strongly hypodense areas(More)
After a period of 10 years the authors reexamined the respiratory health status of 381 dust-exposed males. Of the lung function values examined Raw, RV/TLC%, VC, TGV and PaO2 were found to be of significant prognostic importance. Among the radiological changes characteristic of silicosis the most serious B-C category, among the respiratory complaints(More)
The aim of this study was to examine the effect of intranasal salmon calcitonin therapy on bone mineral density (BMD) in idiopathic male osteoporosis without vertebral fractures. We conducted a randomized, open label, controlled trial in 71 male patients (mean age 59 +/- 6 years) suffering from idiopathic osteoporosis (femoral neck T-score < -2.5) without(More)
The results of 30 years screening of exposed workers in the hard metal industry are presented in a retrospective study. There were 11 workers who had radiographic signs of pulmonary fibrosis. No correlation was found between intensity and/or duration of exposure and the stage and progression of pulmonary fibrosis. In 45% of the cases there was progression(More)
Authors examined 43 caisson-miners with symptoms of the upper extremities because of suspicion of hand-arm vibration syndrome. Also vibration measurements were performed on the pneumatic hammer used by the workers. The acceleration of the vibration exceeded 2.5-3.5 times the maximum allowable level according to the ISO 5349. Symptoms and signs of hand-arm(More)
The possibility of early detection of asbestos-related respiratory diseases was examined on the basis of four x-ray abnormalities, namely, pulmonary fibrosis, pleural plaque, diffuse pleural thickening and diaphragmatic calcification, in a group of workers exposed to chrysotile asbestos. The frequency of these phenomena was compared to the unexposed control(More)
OBJECTIVE What is the frequency of occupational asbestos exposure among patients suffering from malignant respiratory tumours and how many of these tumours are associated with asbestos in Hungary? METHODS An internationally established questionnaire with 29 questions, covering the most characteristic activities of asbestos exposure at the workplace was(More)
