[Its frequency is shown differently by statistics of different authors. Their ratio to total tumors of the brain, according to Anglo-Saxon authors (1), is 1.5% -3.6%. In data from Soviet neurosurgical institutes (2), 2.1–3.4% of all brain tumors were tuberculoma. The reason for the differences in the statistics is that tuberculoma often does not undergo neurosurgery but is detected only by autopsy.]

[Data on the symptoms of damage to the gyrus cinguli and the medial cerebral sulcus]

GERÉB Tibor

[Clinical symptoms of the medial surface of the left hemisphere were analyzed in connection with an astrocytoma destroying the cingulitis of the left gyrus and the contiguous part of the medial surface of the forehead and wall lobe. Some of the epileptic seizures were introduced by euphoria as an aura. This can be interpreted based on the internal organ projection relationships of the medial brain surface, which is also supported by anatomical and experimental data. The onset of epileptic seizures in the hand, resp. his appearance there alone — with anatomically proven sparing of the fibers from the arm center of preecentral cortical representation — can be traced back to the excitement of the additional motor area described by Penfield, just as the speech inhibition observed once. Disorders of personal consciousness (Kleist) were not detectable.]

[Brain tumour and pregnancy]

MAJERSZKY Klára

[1. Data from the literature differ on the association between brain tumor and pregnancy. Some say in animal experiments that pregnancy delays or has no effect on tumor growth, others say it specifically accelerates it. Few cases have been reported in humans in which pregnancy did not adversely affect brain tumor symptoms. In 80% of adverse events, childbirth exacerbated brain tumor symptoms. 2. In 14 years among 221 women with brain cancer , 17 pregnant, resp. we observed patients who already had a brain tumor during the last pregnancy. 3. In six cases, pregnancy and childbirth had no detectable effect on the tumor. With the onset of cancerous symptoms, resp. pregnancy can be directly related to pregnancy in 6 cases and childbirth in 2 cases (47%). In three cases, the co-occurrence of pregnancy and cancer symptoms is apparently an accidental encounter. 4. Based on our own cases, the essence of the issue of the relationship between pregnancy and brain tumor is not the growth retardation or in the problem of acceleratio, but the cases are approx. half of it is seen in the upset of intracranial hydrodynamic balance due to gestational disorders. 5. Things to do change from time to time. Radical neurosurgery or, if this is not possible, subtemporal or posterior scala decompression. In the latter case, cesarean delivery may be recommended. In previously operated cases, if the surgery was not radical or the tumor is prone to recurrence, an abortion is warranted if the patient's condition has not deteriorated. If you have already had threatening tumor symptoms, reoperation is the right solution. In the case of pituitary adenoma, artificial abortion must be performed when the tumor symptoms worsen.]

[Experimental data on the mechanism of the tetanus inhibitory reflex]

KIBÉDI Tibor, DIRNER Zoltán

[1. Our various tetanus interventions: During max. flexion, extension, trunk flexion, and slight compression of the chest, one or more muscle groups are always stretched. Prolongation of muscle or tendon is an adequate stimulus of proprioceptive receptors. Proprioceptive stimuli trigger the tetanus reflex. 2. Tetanus inhibition lasts only as long as the muscle is kept stretched. 3. During inhibition, the animal is capable of appropriate reflex movement. 4. The anti-tetanus reflex, when properly affected, also develops in the spinal cord of an incised animal during transection. 5. Clonus spasms caused by Cardiazol cannot be reduced by effects based on muscle or muscle elongation. 6. If the spinal cord is cut at the height of one of the dorsal segments and then the animal is poisoned with strychnine, the known effect on the pharmacy develops weaker and later during the incision.]

The yield of electroencephalography in syncope

NALBANTOGLU Mecbure, TAN Ozturk Ozlem

Introduction - Syncope is defined as a brief transient loss of consciousness due to cerebral hypoperfusion. Although the diagnosis of syncope is based on a thorough history and examination, electroencaphalography (EEG) is also an important investigational tool in the differential diagnosis in this group of patients. In this study we aimed to identify the diagnostic value of EEG in patients with syncope. Methods - We retrospectively examined EEG recordings of 288 patients with the diagnosis of syncope referred to the Cankiri State Hospital EEG laboratory, from January 2014 to January 2016. The EEG findings were classified into 6 groups as normal, epileptiform discharges (spike and sharp waves), generalized background slowing, focal slowing, hemispherical asymmetries, and low amplitude EEG tracing. The EEGs were separated according to gender and age. Results - Total of 288 patients were included in this study, 148 were females (51.4%) and 140 (48.6%) were males. Among all the EEG reports, 203 (70.5%) were normal, 8 of them (2.8%) showed generalized background slowing and 7 (2.4%) demonstrated focal slow waves. Epileptiform discharges occured among 13 patients (4.5%). Hemispherical asymmetries were detected in 10 patients (3.5%) and low amplitude EEG tracing in 47 patients (16.3%). There was no significant difference between age groups in EEG findings (p=0.3). Also no significant difference was detected in EEG results by gender (p=0.2). Discussion - Although the diagnosis of syncope, epilepsy and non-epileptic seizures is clinical diagnosis, EEG still remains additional method

[Surgically cured resistant epilepsy - caused by hemispherical dysgenesis - Case report]

NEUWIRTH Magdolna, FOGARASI András, BARSI Péter, HEGYI Márta, RUDAS Gábor, BOGNÁR László, SIEGLER Zsuzsa, KOZÁK Lajos Rudolf, LENGYEL Zsolt, SZAKÁLL Szabolcs

[A part of patients with the therapy resistant epilepsy can be cured by surgical interventions. The more concordant the presurgical evaluation data, the better prognosis the patient has postoperatively. In case of discordant examination data, multimodal evaluation or case-specific decision might be successful. We report on a five-year-old boy with bilateral (left-dominated) cortical dysplasia and therapy resistant epilepsy. The ictal EEG did not help to localize the seizure onset zone, semiology had little lateralization value; however, FDG-PET showed left hemispherial hypermetabolism. The child became almost seizure-free and showed improved development after left-sided hemispherotomy.]
