[Glaucomatous optic nerve disease (GOND) is the axonal neuropathy of the optic nerve and this diagnosis should enter the differential diagnosis of patients complaining of progressive diminution of vision. A positive family history is one of the major risk factors. Current theories regard the elevation of intractor pressure only a risk factor of GOND, not as its cause. The pathophysiology of ganglion cell dam- age in GOND in some respect parallels processes in other neurodegenerative disease. Current therapy aims at reducing the intraocular pressure and new forms of therapy, to prevent neuronal death are being developed. ]

[Somatic defects and pain manifested at adults' drawings of a man]

GRYNAEUS Tamás

[The outhor observed that “draw-a-man tests” of mentally retarded or demented adult patients may truly reflect their somatic defects or painful disorders. Drawings of mentally intact patients could also exhibit their somatic illness if it causes pain or the compensating mechanisms are insufficient. A brief discussion is given on the possible mechanisms, in connection with the body-schema.]

[Topographic pattern of spike-waves in absence seizures]

CLEMENS Béla

[Topography of generalized ictal spike-wave patterns (absence seizures) have been investigated by voltage mapping analysis. The 31 patients investigated in this study belonged to a wide variezy of epileptic syndromes with absence seizures. Previously described different topographic patterns of the spike and the wave components have been confirmed in this study.]

[The effect os levodopa in Parkinson's disease ]

MECHLER Ferenc, DIÓSZEGHY Péter, GLAUB Theodóra, HIDASI Eszter, JOSE Rosa

[The effect of carbidopa/levodopa on clinical signs and laboratory data was studied in 21 patients with Parkinson's disease during a follow-up period of 7-12 months. The Columbia and Webster scales were used for analysis. The improvement was significant already in the first weeks of the treatment. The drug did not influence the laboratory data and the side effects were found to be insignificant. The changes due to the drug were analysed by electrophysiological methods. Certain peak amplitudes and the area of visually evoked responses increased significantly during the treatment suggesting facilitation in the function of visual pathways. On stimulating the motor system by transcranial and spinal magnetic stimulation, the motor latencies and the duration of silent period showed normalization. ]

[The prognostic relevance of apoptosis in medulloblastoma]

SCHUBERT EO Thomas, CERVOS-NAVARRO Jorge

[Apoptosis is known to be a phenomenon of prognostic significance in certain neoplasms. Several previous studies have indicated that the prognosis of desmoplastic medulloblastoma is better than that of classical medulloblastoma. We studied 5 desmoplastic and 5 classical medulloblastomas by in situ end labelling of DNA strand breaks to see whether there is any difference in amount or pattern of apoptosis in these subtypes, correlating to the different prognostic behaviour. We found no significant difference neither in amount nor in pattern of apoptosis between the two subtypes. Our results indicate that apoptosis may not be a relevant variable in the prognosis of medulloblastoma.]

[Thrombolytic therapy in acute ischemic stroke (preliminary report)]

HAFFNER Zsolt, HORVÁTH Erzsébet, HORVÁTH Éva, PAPP Gabriella, EGERVÁRI Ágnes, LIPÓTH Sarolta, CSÁNYI Attila, TUKA Andrea

[Intravenous stretiokinase infusion therapy was performed on four patients in acute occulsive cerebrovascular disease (hemorrhage was rxcluded by CT scan). The thrombolytic therapy was started not later than six hours after the onset of the first symptoms. Kabikinase (1 250 000 IU) was administered in intravenous infudion during two hours. After thrombolysis no prolonged anticoagulant therapy was applied. Improvement of the neurological symptoms was impressive and convincing: in two cases immadiate. Ino one case we could be observed during the treatment (2 hours) nor after it. The possibility of thromolytic therapy in acute occulsiv stroke should be take into consideration. So far as we are aware this is the first time that thromolysis is occulsive stroke according to a protocol like this has been used in Hungary.]

[Clinical aspects of ischaemic bowel disease]

DEMETER Pál

[Decreased blood flow through the intestines leads to mesenteric ischaemia, which is characterised by cellular damage due to the lack of oxygen and nutrients. Extensive collateralisation between splanchnic vessels serves as a protective mechanism against ischaemia. Intestinal ischaemia can be classified on the basis of its timing, location and the vessels involved. Acute mesenteric ischaemia can result from arterial embolisation, arterial or venous thrombosis, or vasoconstriction secondary to systemic circulation disorder associated with hypovolaemia. Chronic mesenteric ischaemia develops as a consequence of partial or complete occlusion of splanchnic vessels. Colonic ischaemia is mainly caused by a limited circulation disorder of the inferior mesenteric artery. Mortality rates for the various forms of acute mesenteric ischaemia are different. However, early diagnosis before bowel infarction might improve survival. This paper summarises the cilical aspects, diagnosis and therapeutic options of intestinal ischaemia.]

[Faces of dementia]

FULLAJTÁR Máté, HIDASI Zoltán

[Dementia is defined as a combination of symptoms or as a syndrome. In different types of dementia syndromes cognitive, behavioural and psychological symptoms can be distinguished according to clinical aspects. The prevalence of dementia increases continuously with age, causing significant challenges for the health care system of developed countries. Early diagnosis and early intervention by progression slowing therapy can be defined as goals in treating dementia. At the same time, the education and psy­chological support of the patients, their relatives and health care providers are also essential. A more accurate knowledge of the pathomechanisms behind the symptoms is ne­cessary in order to develop more effective therapies in the future. The authors review the most important types of mild cognitive impairment and dementia syndromes, their clinical and diagnostical criteria and therapeutic possibilities, focusing on early diagnosis and prevention.]

[New possibilities in the management of hepatocellular carcinoma]

DANK Magdolna

[The prognosis of primary hepatocellular carcinoma (HCC) has been poor until recently. Most patients are diagnosed at an advanced stage, with a poor liver function, thus therapeutic possibilities are limited. In high-risk patients, active surveillance and HCC screening is essential for early diagnosis. Experience with systemic chemotherapy has been disappointing with low response rates and high rates of adverse effects. Recently, novel treatment options have emerged, including the use of specific targeted agents, blockers of signaling pathways involved in hepatocarcinogenesis. Sorafenib, an oral multikinase- inhibitor is the first systemic agent to demonstrate survival benefit in advanced hepatocellular cancer. Several new, promising therapeutic options are being tested in clinical trials. The present review gives an overview of evolving diagnostic and therapeutic strategies.]
