[The subdural strip-electrode technique was introduced in the eighties in the USA. An account is given here of the first Hungarian experience with this method using implantates developed by us. The properties of the electrodes and the use of the technique are described under chronic and intraoperative conditions. In 8 patients the strips were used to localize the pacemaker zone of the seizures in those cases where the scalp EEG and neuroimaging data were discordant. Two temporal, 4 frontal and 2 parietal lobe epileptic patients were studied. Sixty-six seizures were recorded and on 15 occasions the strips were used for intraoperative corticography. The chronically implanted electrodes provided safe conditions for recording and by means of these we obtained additional information in all the cases studied thereby contributing to the indication of surgery or in the rejection of a surgical solution. The mobility and flexibility of the strips make them an ideal tool for corticography. With the strips the invasivity of presurgical evaluation was reduced.]

Clinical perspectives of the new, reversible and selective MAO-A inhibitors

VOLZ H P, GLEITER C H, MÖLLER H J

The classical monoamine oxidase inhibitors are used with great care due to their potency to induce severe side effects caused by tyramine interactions from food. With the advent of reversible and selective inhibitors of monoamine oxidase type A their interaction potential was considerably reduced. The first compounds are brofaromine and moclobemide, the latter already, registered for five years in Europe. The paper reviews the essential pharmacological properties of both compounds and gives a survey of the relevant clinical trials. Their efficacy in major depression is established. Regarding therapy resistant depressions, a certain advantage of brofaromine seems to exist. Promising trials in social phobia and panic attacks have been performed with both drugs.

[Dysfunctional personality attitudes and depression amng adolescents suffering from migraine-type headache]

CSORBA János, FARKAS Viktor, MIHÁDÁK Katalin

[Authors compared a clinical sample of adolescent migraine patients (n=28) aequal in age mean sex ratio with a group of healthy control adolescents (n=68) to demonstrate some differential psychological characteristics of adolescents suffering from migraine. The Dysfunctional Attitude Scale (Burns) and Beck's Depression Inventory were used. The patient sample achieved an increased scores on Approval, Entitlement and Omnipotence scales as well as the group showed a greater total means of the DAS scale, but an unexpectedly lower level of Depressivity has been proved in the clinical sample. Both DAS variables and BDI characterize the two groups better, than clinical features, but besides sufficient sensitivity only moderate specificity was managed to achieve on classification by means of discriminant analysis. Migraneous adolescents do not suffer from depressivity, only gradual differences between the two samples have been found.]

[Multiple aspects study of short term memory performance in two diagnostic groups of epileptic patients]

BARCS Gábor, VITRAI József, HALÁSZ Péter

[The short term verbal and the visuo-spatial memory performance of 37 temporal lobe, 30 idiopathic generalized epileptic patients, and 24 normal control individuals were studied by interactive computerized tests. The short term visuo-spatial memory performance of epileptic patients was basically determined by the Raven IQ and strongly influenced by the seizure frequency and sustained attention while the verbal memory performance seemed to be independent of these parameters. The verbal memory performance of temporal lobe epileptic patients on carbamazepine monotherapy was lower compared to the idiopathic generalized epileptic patients on valproate monotherapy and to the normal controls. The difference between the performance of temporal lobe epileptic patients and normal controls was statistically significant. The memory performance in the group of temporal lobe epileptics proved to be independent of the laterality of the affected side. Concerning the short term visuo-spatial memory, after the factors having influence on the memory were ruled out, there was no difference between the controls and patients. Memory performance was not influenced by the duration of the illness nor by the type of antiepileptics used. In a treatment resistant group of idiopathic generalized epileptic patients, without considering other factors having influences on the memory, the visuo-spatial memory performance was even lower than the performance of the temporal lobe epileptic patients.]

[Intracranial respiratory epithelial cysts: report of two cases]

VARGA Zs, VAJTAI I, BODOSI M, VÖRÖS E

[The authors report two cases of leptomeningeal cysts with unusual histologic features. Both cysts originated in the subarachnoid space of the left Sylvian fissure, being solitary in one case and multiocular in the other. Symptoms in both cases were referable to intracranial space occupation. Both lesions were resected surgically. Microscopically, the cyst walls were predominantly lined with pseudostratified and ciliated columnar or non-keratinizing squamous epithelium reminiscent of various segments of the respiratory mucosa. Ependymal covering was present only focally. The cellular elements displayed a characteristic immunophenotype and there was evidence for mucin production. Intracranial respiratory epithelial cysts are distinctly rare. While a dysontogenic origin is presumed for such cysts are distinctly rare. While a dysontogenic origin is persumed for such cysts along the spinal cord, intracranial occurrences are most plausibly interpreted as a result of metaplastic transformation of the meningeal anlage induced by cyst expansion. ]

[Simultaneous occurrence of cavernous angioma and developental venous anomaly]

KUNCZ Ádám, VÖRÖS Erika, BODOSI Mihály

[The significance of the simultaneous occurrence of cavernous angioma and developmental venous anomaly, the diagnostic possibilities and the surgical treatment are discussed based upon three cases. Angiography and magnetic resonance imaging together are necessary to get an accurate diagnosis. According to the literature and to the fact that it is the cavernous angioma that mainly causes the symptoms, the cavernosus angioma should be resected, while the developmental venous anomaly should be spared.]

Effects of valproate, carbamazepine and levetiracetam on Tp-e interval, Tp-e/QT and Tp-e/QTc ratio

YASAR Altun, ERDOGAN Yasar

Aim - To evaluate P-wave dispersion before and after antiepileptic drug (AED) treatment as well as to investigate the risk of ventricular repolarization using the Tpeak-Tend (Tp-e) interval and Tp-e/QT ratio in patients with epileptic disorder. Methods - A total of 63 patients receiving AED therapy and 35 healthy adults were included. ECG recordings were obtained before and 3 months after anti-epileptic treatment among patients with epilepsy. For both groups, Tp-e and Tp-e/QT ratio were measured using a 12-lead ECG device. Results - Tp-e interval, Tpe/QT and Tp-e/QTc ratios were found to be higher in the patient group than in the control group (p<0.05, for all), while QTmax ratio was significantly lower in the patient group. After 3 months of AED therapy, significant increases in QT max, QTc max, QTcd, Tp-e, Tp-e/QT, and Tp-e/QTc were found among the patients (p<0.05). When the arrhythmic effects of the drugs before and after treatment were compared, especially in the valproic acid group, there were significant increases in Tp-e interval, Tp-e/QT and Tp-e/QTc values after three months of treatment (p<0.05). Carbamazepine and levetiracetam groups were not statistically significant in terms of pre- and post-treatment values. Conclusions - It was concluded that an arrhythmogenic environment may be associated with the disease, and patients who received AED monotherapy may need to be followed up more closely for arrhythmia.

Management of bone metabolism in epilepsy

UÇAN TOKUÇ Ezgi Firdevs , FATMA Genç, ABIDIN Erdal, YASEMIN Biçer Gömceli

Many systemic problems arise due to the side effects of antiepileptic drugs (AEDs) used in epilepsy patients. Among these adverse effects are low bone mineral density and increased fracture risk due to long-term AED use. Although various studies have supported this association with increased risk in recent years, the length of this process has not been precisely defined and there is no clear consensus on bone density scanning, intervals of screening, and the subject of calcium and vitamin D supplementation. In this study, in accordance with the most current recommendations, our applications and data, including the detection of possible bone mineralization disorders, treatment methods, and recommendations to prevent bone mineralization disorders, were evaluated in epilepsy patients who were followed up at our outpatient clinic. It was aimed to draw attention to the significance of management of bone metabolism carried out with appropriate protocols. Epilepsy patients were followed up at the Antalya Training and Research Hospital Department of Neurology, Epilepsy Outpatient Clinic who were at high risk for osteoporosis (use of valproic acid [VPA] and enzyme-inducing drugs, using any AED for over 5 years, and postmenopausal women) and were evaluated using a screening protocol. According to this protocol, a total of 190 patients suspected of osteoporosis risk were retrospectively evaluated. Four patients were excluded from the study due to secondary osteoporosis. Of the 186 patients who were included in the study, 97 (52.2%) were women and 89 (47.8%) were men. Prevalence of low bone mineral density (BMD) was 42%, in which osteoporosis was detected in 11.8% and osteopenia in 30.6% of the patients. Osteoporosis rate was higher at the young age group (18-45) and this difference was statistically significant (p=0.018). There was no significant difference between male and female sexes according to osteoporosis and osteopenia rates. Patients receiving polytherapy had higher osteoporosis rate and lower BMD compared to patients receiving monotherapy. Comparison of separate drug groups according to osteoporosis rate revealed that osteoporosis rate was highest in patient groups using VPA+ carbamazepine (CBZ) (29.4%) and VPA polytherapy (19.4%). Total of osteopenia and osteoporosis, or low BMD, was highest in VPA polytherapy (VPA+ non-enzyme-inducing AED [NEID]) and CBZ polytherapy (CBZ+NEID) groups, with rates of 58.3% and 55.1%, respectively. In addition, there was no significant difference between drug groups according to bone metabolism markers, vitamin D levels, and osteopenia-osteoporosis rates. Assuming bone health will be affected at an early age in epilepsy patients, providing lifestyle and diet recommendations, avoiding polytherapy including VPA and CBZ when possible, and evaluating bone metabolism at regular intervals are actions that should be applied in routine practice.

[Personalised epilepsy treatment]

ALTMANN Anna

[Epilepsy is one of the most common chronic neurological disease in childhood. Patients with epilepsy – even with so-called benign epilepsy – need medication for years. During this time, children go through a very big change, not only gaining weight and height, but also changing hormonal and metabolic processes. Maturation processes in different brain areas also take place at different rates depending on age. All of these should be considered when preparing a therapeutic plan. In everyday practice after the diagnosis of epilepsy, the applied drug is most often selected based on the shape and type of seizure. However, a number of other factors need to be considered when designing a therapeutic strategy: 1. efficacy (form of epilepsy, type of seizure), 2. age, gender, 3. pharmacological properties of the drug, 4. adverse drug reaction profile, 5. lifestyle (community), figure (skinny, corpulent, obese), 6. other comorbidities (nutrition, behavioral and learning problems, circulatory disorders, kidney or liver disease), 7. expected interactions with other drugs already used, 8. genetics, 9. other aspects (drug registration and prescription rules). The purpose of this article is to help to decide which antiepileptic drugs are expected to have the least side effects in a particular child with different comorbidities and which medications should be avoided if possible.]

[Epilepsy in coronavirus pandemic]

SZŰCS Anna, HALÁSZ Péter, NARULA Lalit

[We aim to review the impact of COVID-19 pandemic on epilepsy and epilepsy-care. While the virus has no specific link with epilepsy, it may affect the nervous system both directly and indirectly, leading to seizures in several ways. The hyper-coagulable state occurring with the infection may cause strokes leading to seizures. The infection may first manifest in the form of disturbances of consciousness and behaviour, seizures, and even status epilepticus. The interactions of antiviral/antiepileptic drugs need to be taken into account during treatment. The hypercoagulable state induced by COVID-2 infection may cause stroke, which leads to seizures. The infection can occur also as an impaired consciousness of non-epileptic origin. Interactions of antiviral/antiepileptic drugs have also to be taken into account. The pandemic itself as well as quarantines and social distancing may cause anxiety and insomnia, challenge continuous antiepileptic supply; each one carrying the risk of seizing. Young epilepsy patients with learning disabilities and mental health issues are most vulnerable, justifying their hyper-protection. The danger of infection has highlighted the role of telemedicine. Internet-based video communication may ensure full care for chro­nic patients. Those methods favour bes­­ted patients with higher education. Epilepsy does not increase directly the risk of infection, but its comorbidities may worsen the course of the disease. Brain lesions and hypoxia, stress, insomnia and fever joining the infection increase seizure susceptibility. Because the danger of infection ma­de telemedicine an essential tool of pa­tient care, education and better computer supply for those in need is crucial. ]

[The role of zonisamide in the treatment of women with epilepsy]

JUHOS Vera

[The antiepileptic drugs can effect fertility, development of gynecological diseases and occurence of sexual problems. They can cause a number of “cosmetic” problem and also influence the selection of safe contraceptive method. Many antiepileptic drugs can cause congenital malformations or affect the new-born child’s psychomotor and cognitive development, therefore during pregnancy should be treated with extreme caution in women with epilepsy. Most types of epilepsies accompany the patient through their whole life. Women spend almost the third of their lives after menopause and - due to the formation of associated diseases as well - this period is also special. According to the 2013 recommendation of International League Epilepsy (ILAE), zonisamide is one of the first-line antiepileptic drugs in focal epilepsy. In my review I discuss women’s epilepsy in the viewpoint of the application of zonisamid. ]
