[Changes in the fibre contingent and caliberspectrum of spinal anterior roots in amyotrophic lateral sclerosis]

SZENDRŐI Mária, BOZSIK György

[Authors have processed 88 spinal anterior peduncles from 10 ALS cases. The fibre count and caliber measurement data showed that the cervical and thoracic anterior roots were most affected. Lesions were more modest in the lower thoracic and lumbar segments. The reduction in the number of root fibres was very marked in some cases. In ALS, the caliberspectrum varies, with the decrease in the number of thicker fibres (8-10 Y) being the earliest and most significant.]

[Cerebral blood flow studies using the isotope dilution method]

SZÁNTÓ József, GALLYAS Ferenc

[The authors present cerebral circulation data from a few patients in whom characteristic circulatory dynamics abnormalities were found, using their modified version of the isotope fluctuation circulation test method to demonstrate the performance of the method. The method allows a large number of circulatory data to be determined simultaneously (circulation times, blood flow through the brain, brain blood volume, cardiac output, circulating blood volume). From the shape and the relative position of the dilution curves, it is also possible to deduce circulatory dynamic abnormalities: e.g. thrombosis of the carotid intima-media, vascular malformations and, from the confusion in the arterial phasis, pathological processes of arterial origin in one hemisphere.]

[The significance of orbital congestion in the diagnosis of closed head injury]

ÁFRA Dénes, NAGY Vilmos

[Parietal congestion occurred in 43 of 259 closed head injury cases 1-6 weeks after the accident. During the subacute phase, 9 of 44 intracranial haematomas presented with congestive papilledema, while 11 of 103 patients without a space-occluding haemorrhage presented with the same fundus lesion. In the chronic period congestion of the fundus always occurred in the presence of subdural haematoma with one exception. The examination findings of the injured patients without haematoma with congestion included moderate disturbance of consciousness, neurological nodal symptoms, corresponding EEG abnormalities and abnormal CSF values. The contrast studies performed gave normal images with two exceptions. Moderate vascular dislocation in one patient and marked vascular dislocation in the second patient on AP angiogram resolved after 14 days of contrast. The subacute subocular lesion can be interpreted as a symptom of diffuse or circumscribed posttraumatic cerebral oedema, which always plays a role in the clinical picture. The suspicion of intracranial haemorrhage necessarily requires a contrast study (carotid angiography). ]

[Effect of local hypothermia on brain electrical activity. Application of Peltier effect cooling head ]

PÁSZTOR Emil, TOMKA Imre, DEÁK György

[1. The Peltier effect cooling head is suitable for localized but well-controlled surface cooling of the brain. 2. Based on theoretical calculations and practical measurements, the limits of the deep penetration of surface cooling are determined. 3. Provided new data on the effects of surface cooling on brain electrical activity and strychnine spike activity. 4. We investigated the effect of local cooling on epileptiform electrical activity during surgery in a patient with temporal epilepsy.]

[Polyarteritis nodosa manifesting as neuro-radiculo-myelitis]

KÖNYVES-KOLONICS László, PÉLEY Domokos, HARASZTI Antal

[Authors describe a monosystemic case of polyarteritis nodosa localized only to the nerves. Clinically, in addition to the typical general symptoms and the typical course of the disease, organ symptoms were observed only in the nervous system. Detailed pathological and histopathological examination was consistent with clinical signs. Typical pathological lesions were found in the brachial vaso-anatritis of the brachial plexus, the veins of the cerebellar cortex, the bridge and the upper segments of the spinal cord.]
