[Hemodynamic adaptation of fetal brain]

JAKOBOVITS Ákos, HENDRIK Jörn

[Doppler color ultrasonography of the middle cerebral and umbilical arteries was performed on 104 fetuses born at term. A total of 254 investigations were carried out. Of the 104 fetuses studied, 52 infants had birth weights appropriate for gestational age (mean 3409.2 g) and 52 infants were small for gestational age (mean 2272.1 g). Cerebral hemodynamic adaptation was observed in growth retarded fetuses due to placenta! insufficiency. ln these cases the elevated umbilical vascular resistance... tovább »

[Distal Ulnar Neuropathies]

KISS Gábor, KÓMÁR József

[Compression of the distal part of the ulnar nerve is an uncommon entrapment neuropathy. Depending on the site of compression it may result in pure motor symptoms. The atrophy of the small hand muscles without sensory deficit may mimic motor neuron disease. Correct clinical examination and electrophysiology including measurement of ulnar distal motor latency to the first dorsal interosseous muscle can reveal the correct diagnosis. 46 surgically treated cases of distal ulnar neuropathy are... tovább »

[Importance of sociological and psychological factors in pathogenesis of ischaemic stroke]

MENDE Lilla, JÓRI Birkás Adrien, FAZEKAS Gábor, FAZEKAS András

[The authors investigate sociological and psychological factors in the pathogenesis of ischaemic stroke, as a follow up of their earlier study. In the first part of the recent study patients and control subjects are compared in terms of frequency, severity, type and the temporal distribution of life events within the 5 years preceding the stroke. In the second part the importance of coping-style and psychological characteristics are studied. It is shown that the likely factors leading to stroke... tovább »

[Transoesophageal echocardiography after stroke]

NAGY Lajos, SÁMOCYI Marianna, TARJÁN Jenő, GARZULY Ferenc

[40 stroke patients were studied by both transoesophageal and transthoracic echocardiography. The diagnosis of stroke was based on medical history, physical examination and computerized tomographic brain scan. 39 patients underwent carotid duplex scan as well. Transoesphageal echocardiography was used to examine 40 patients of whom 19 had cardiac source of embolism. Out of these, 7 patients had definitive, whereas 12 had possible cardiac source of embolism. Transthoracic echocardiography was... tovább »

[Prognosis of neuroepithelial tumours by means of cell proliferation studies]

GYÖMÖRI Éva, MÉSZÁROS István, MÉHES Gábor, DÓCZI Tamás, PAJOR László

[Cell-kinetic analysis of tumours has recently been widely used in clinical oncology for prognosis of patients treated with malignant neoplasms and for controlling the efficiency of treatment protocols. Definition of biological nature of neuroepithelial tumours was based on grading depending on the severity of cellular anaplasia. Neuroepithelial tumours can be characterized not only by the histological features but also by the DNA content and abnormalities of the cell proliferation – though the... tovább »

[Apolipoprotein E4 as a genetic risk factor in Alzheimer's Disease]

KÁLMÁN János, JANKA Zoltán

[Apolipoprotein E (apoE) is a glycoprotein participating in the lipid transport and metabolism and in the neuronal regeneration processes. The gene of apo (APOE) is localized on the long arm of chromosome 19. The genetic polymorphism of APOE is manifested in three common alleles. The frequencies of these alleles, APOE2, APOE3, APOE4 are different in various human populations depending on their geographical origin. The APOE alleles have been considered to be responsible for the inter-individual... tovább »

KTP/532 precutaneous laser decompression for lumbar disc prolapse

MARTIN T. N. Knight, SAMUEL T. Pantoja

The efficacy of percutaneous laser disc demompression with the potassium titanyl phosphate laser (KTP/PLDD) for the treatment of sciatica due to lumbar disc prolapse was evaluated in a consecutive series of 109 patients. All patients had low-back pain and leg pain with positive tension signs and had received conservative treatment for an average of 11.4 (1-28) months without relief of symptoms. Disc porlapse was confirmed by computed tomography or magnetic resonance imaging and evaluated with... tovább »

[Trigeminovascular hypothesis of cluster headache]

TAJTI János, SZOK Délia, VÉCSEI László

[Cluster headache is a rare, very severe disorder which is clinically well characterized with a relatively poorly defined pathomechanism. Concerning the pathomechanism of cluster type headache, from the clinical symptoms three things can be inferred. The fact that head pain is centred dominantly around the eye and fore head makes it probable that the unilateral trigeminal nociceptive pathways are involved. Lacrimation and rhinorrhoea suggest the activation of the parasympa thetic, while ptosis... tovább »
