[The significance of diagnostic errors in brain tumours]

GÁTAI György

[A more significant reduction in errors can only be achieved if the sources of error are made known and if education, organisation and the various disciplines are involved and assisted. We must take every opportunity to give the issue publicity commensurate with its importance. This is the third, but not the last, reason for discussing the diagnostic problems of brain tumours and the importance of early diagnosis. ]

[Investigating factors in the development of neuromorbidity in female phonophonists]

BÁLINT István, HÓDOS Tibor

[The authors used a statistical analysis to determine the place of the textile industry, and within it the spinning mills, in the structure of the industry's neuro-morbidity. This showed that spinning mills have been ranked second or third for several years with high rates of neuro-morbidity. An investigation of the role of occupational factors in causing this neuro-morbidity was carried out in one of the spinning mills with a high neuro-morbidity rate. The most relevant components of physical stress, static work, are identified as high temperatures, high relative humidity, insufficient lighting, high noise exposure, which are now technologically unjustified. Measurement data are provided for these. The dominant factor in psychological stress is considered to be the need for sustained attention and the need for constant attention-sharing. The lack of breaks between work periods is considered to be an indication of inadequate work and rest patterns. The results of the attention span and hand tremor tests of neurotic and control groups showed that neurotics were significantly more fatigued in the middle of the shift than controls. As a call to reduce the overall workload, the instrumental test results of the control subjects at the end of the shift were found to differ only non-significantly from those of the neurotics. ]

[Amino acid distribution in cerebrospinal fluid (I.) Arginine]

SZILÁGYI Á. Katalin, PATAKY István

[Colorimetric arginine determinations were performed in CSF cerebrospinalis and serum, which were found normal by routine laboratory methods. It was concluded that the conflicting values in the world literature could be explained by the site of CSF collection and the amount of CSF taken, because the arginine content of cysternal CSF is higher than that of lumbar CSF. A correlation has been found between the arginine level in lumbar CSF and the serum level found in the same individual. There also appears to be a numerical correlation between CSF arginine levels and age (decreasing progressively with advancing age), but this correlation is not statistically proven. ]

[Changes in brain bioelectrical activity in experimental hyperoxia]

SZÁM István, NIKOLITS Ilona, GOTTSEGEN György

[The electroencephalogram of experimental rats exposed to oxygen at 3.7 atm - recorded by means of built-in cortical electrodes - shows coarse, non-specific amplitude and frequency changes and spike discharges. The onset of EEG changes precedes the onset of respiratory and cardiac impairment and the earliest phase of the development of 'hyperoxic' pulmonary oedema; arterial blood 02 saturation is also normal at this time. The sequestration of CO2 produced by the animals, and thus the prevention of CO2 rebreathing, delays the onset of EEG changes and partially prevents the development of spike potentials. Impaired bioelectrical activity in the brain is the earliest symptom of oxygen toxicity. ]

[Large intracerebral aneurysm case]

EPSTEIN Ottó, VAATAY Irén

[The authors describe a case of a large intracerebral aneurysm in the right frontal lobe, which probably caused at least two small haemorrhages and neurological symptoms. In the end, it produced mainly psychiatric lesions in addition to milder neurological symptoms, and these required the patient to be admitted to a psychiatric ward. Death was caused by intercurrent bronchopneumonia, whereas at autopsy the aneurysm was intact and the symptoms observed were causally related to the location and size of the aneurysm and the pressure it exerted. ]

[Carotid angiography in elderly and arteriosclerotic patients]

SZEGEDY László, HAITS Géza

[Authors report on 422 carotid angiographies performed in elderly patients with cerebrovascular damage. No complications were observed in any of the 482 angiographic studies. 64 patients showed marked improvement after angiography. Authors analyze the problems of angiography in vascular patients based on literature data and their own patient records. ]
