[Effects of Propofol and Thiopental on median nerve somatosensory evoked potentials and cerebral blood velocity]

MÉSZÁROS István, KASÓ Gábor, BÜKI András, HUDVÁGNER Sándor, PFUND Zoltán, DÓCZI Tamás, NAGY Ferenc

[Effects of induction doses of thiopental and propofol on median nerve somatosensory evoked potentials and cerebral blood flow velocity were investigated in 50 patients suffering from degenerative lumbar spine diseases before operation and during anaesthesia. The propofol influences the cerebral electric activity and the blood flow velocity to a less extend than thiopental. Based on our results we prefer to employ propofol during neurosurgical procedures when using intraoperativ somatosensory... tovább »

[Three dimensional time of flight magnetic resonance imaging in trigeminal neuralgia]

VÖRÖS Erika, SZENTGYÖRGYI Réka, KUNCZ Ádám, MENCSER Zsolt, KARDOS Lilla, MILASSIN Péter

[The purpose of our study was to evaluate the role of three dimensional time of flight magnetic resonance angiography in detection of neurovascular compression in patients with trigeminal neuralgia. 53 patients (26 males, 27 females mean age 57 years) with trigeminal neuralgia underwent 3D TOF MRA. Examinations were performed on 0.5 T Elscint Gyrex V Dlx equipment. The imaging parameters were 33-38/9/25 TR/TE/flip angle with 30-50 mm slab thickness and 1-1.5 mm slice thickness.

[Uremic polyneuropathy - clinical and electrophysiological analysis]

PFUND Zoltán, CZOPF József, NAGY Ferenc

[Uremic polyneuropathy is a consequence of chronic renal failure, and is one of the symptoms of the uremic syndrome. Its etiology is not well known, several neurotoxins are presumed as pathogenic factors. Both axonal lesions and demyelinization are involved in the development of neuropathy 66 electrophysiological studies (EMG, ENG) in 57 uremic patients were performed in our department between 1978 and 1988. The correlation between clinical and electrophysiological findings are discussed.... tovább »

[Mental disorders after stroke (treatment of post-stroke depression with moclobemide)]

VARGA Dániel, PÉK Márta, NAGY Zoltán

[Post-stroke states are usually characterized by residual neurologic symptoms and movement performance, while psychological disturbances remain hidden. Stroke patients frequently present mood disturbances, cognitive decline, anxiety disorders, sometimes serious schizophorm and paranoid states. Among them, post-stroke depression is the most common and possibly amenable form to therapeutic intervention. Depression has negative effect on rehabilitation, quality of life and even long term survival.... tovább »

[The genetic diagnosis of leber's hereditary optic neuropathy]

HORVÁTH Rita, ERIC A. Shoubridge, KATHERINE Fu, SOMLAI Judit, HAJDA Márta, KARCAGI Veronika, KOMOLY Sámuel

[We observed the occurence of Leber's hereditary optic neuropathy associated mitochondrial point mutations in patients with bilateral optic neuropathy. DNA samples isolated from peripheral venous blood by the phenol/chloroform method were tested with the help of PCR for the pathogenic Leber's hereditary optic neuropathy associated mitochondrial point mutations. From 14 patients suffering from bilateral visual impairment Leber's hereditary optic neuropathy associated mitochondrial point... tovább »

[Anatomical basis of endoscopic ventriculostomy - clinical application of the free hand technique]

RESISCH Róbert, PATONAY Lajos, JULOW Jenő

[The anatomical basis of the "free hand” technique in treatment of occlusive internal hydrocephalus, viz. endoscopic ventriculostomy, is discussed. In 25 cadavers the cella media of the lateral ventricle was endoscopically approached through a frontoparietal (15 cases), frontal (5) and biportal coronal (5) burr hole. Using the identified structure of the choroid plexus the foramen of Monro was investigated. Via this route, the endoscope advanced into the 3rd ventricle, then the localization of... tovább »

[Analysis of the EEG changes caused by subcortical stroke based on chaos theory ]

MOLNÁR Márk, GÁCS Gyula, ÚJVÁRI Gábor, SKINNER E. James, KARMOS György

[The conventional electrophysiological methods used to analyse the functional characteristics of the nervous system are not able to grasp its non-linear and random features. Of the methods based on chaos theory, correlation dimension analysis can be used to quantify the complexity of the analysed signal, such as the elektroencefalogram. The new version of this method - developed by the authors -, the point correlation dimension is more accurate than other currently used algorithms. The purpose... tovább »

[Report on Parkinson's Disease XII. international symposium]

DIBÓ György

[A major scientific meeting on this topic was held in London from 23 to 26 March 1997 at the Queen Elizabeth II Convention Centre, near Westminster. Two of the symposia held prior to the Congress should be highlighted: a round table on the role of the glutamate system in the treatment of Parkinson's disease, organised by Merz (Frankfurt), and a press conference on the issue of multisystem atrophies (MSA). ]
