Összefoglaló. Bevezetés és célkitűzés: A terápiarezisztens fokális epilepsziák sebészeti kezelése elterjedten használt kezelési lehetőség. Célunk az epilepsziasebészet-hatékonyság változásának vizsgálata egy évtizednyi távlatból a budapesti centrumban. Módszerek: Az Országos Klinikai Idegtudományi Intézetben reszektív epilepsziasebészeti beavatkozásokon átesett fokális epilepsziás betegek adatai kerültek feldolgozásra. A vizsgált 10 év beteganyagát két periódusra osztottuk a műtét időpontja szerint (2006-2010 és 2011-2016). Vizsgálati szempontjaink: demográfiai adatok, az epilepszia kezdete és típusa, mágnesesrezonancia-lelet, preoperatív rohamfrekvencia, műtéttípus és szövettani lelet. Az epileptológiai kimenetelt az Engel-klasszifikáció alapján értékeltük. Eredmények: Epilepsziasebészeti beavatkozás 187 betegen történt, akik közül 137-nél került sor reszekciós műtétre. A betegek 65%-ában temporalis, 18%-ában frontalis, míg 7%-ában olyan multilobaris epilepszia igazolódott, mely a temporalis vagy a frontalis lebenyt érintette. Teljes rohammentességet (Engel I/A) az 1. évben 68%-ban, a 2. évben 64%-ban, míg az 5. évben 63%-ban mértünk. A két intervallum összehasonlításakor az 1 éves rohammentesség aránya 60%-ról (temporalis: 67%, extratemporalis: 50%) 73%-ra (temporalis: 79%, extratemporalis: 62%) javult a második periódusban. Az etiológia szempontjából a hippocampalis sclerosis aránya 28%-ról 14%-ra csökkent, a fokális corticalis dysplasiák aránya 22%-ról 31%-ra növekedett. Következtetés: A sebészeti kezelés fokális epilepsziák esetén - alapos előzetes kivizsgálást követően - általában biztonságos és a legnagyobb arányban sikeres beavatkozás. A legkedvezőbb kimenetel temporalis lokalizációban érhető el. A hatékonyság az évek során egyre javuló tendenciát mutatott az egyre nehezebb sebészeti esetek ellenére. Ez magyarázható a sebészeti technikák fejlődésével, illetve a jobb, műtét előtti elektrofiziológiai és képalkotó technikákkal, amelyek bevezetésével pontosabb lokalizáció adható. Orv Hetil. 2021; 162(6): 219-226., Introduction and Objective: The surgical treatment of medically intractable focal epilepsies is a well established practice. Our aim was to examine the efficacy of epilepsy surgery within a decade long period in our centre in Budapest., Methods: Data of drug-resistant patients with resective epilepsy surgery in the National Institute of Clinical Neurosciences were evaluated. The examined 10-year period was divided based on the year of the operation in two parts (2006-2010 and 2011-2016). The following data were collected: demography, beginning and type of epilepsy, magnetic resonance, preoperative seizure frequency, type of surgery and histology. Epileptological outcome was based on modified Engel's classification., Results: Out of 187 surgeries, we identified 137 patients with resective intervention: 65% temporal lobe, 18% frontal, and 7% multilobar epilepsy. Seizure-freedom (Engel I/A) was 68% in the first postoperative year, 64% in the second, and 63% in the fifth year. In the first period, 1-year seizure freedom was 60% (temporal: 67% extratemporal: 50%), while in the second period it was 73% (temporal 79%, extratemporal 62%). Hippocampal sclerosis ratio dropped from 28% to 14%, while focal cortical dysplasia ratio increased from 22% to 31%., Conclusion: Surgical treatment in focal epilepsy - after thorough presurgical evaluation - is generally safe and successful. The most favorable outcome is in temporal localization. The efficacy tended to improve over time despite of the more challenging cases. This can be explained with the development of surgical techniques and improvement of presurgical localization. Orv Hetil. 2021; 162(6): 219-226.

Introduction: In some surgical wards residents start to do laparoscopic operations using both hands, while in other places they only use their dominant hand, and only start to use both hands later. There are no data at the moment about which method is more effective., Methods: We divided 20 students with no laparoscopic experience into 2 groups: one group practised one hand at a time (1K), the other group used both hands (2K) during the 5 days. On the last day both groups had to do every exercise with one hand and two hands as well, then they had to do 3 new exercises, which needed both hands. We measured the time taken, and gave points for the videos taken inside the training box based on OSATS. For statistical analysis we used t-tests, p < 0.05 being significant., Results: On the first day, there was no significant difference between the 1K and 2K groups considering the time taken (518/500 s) and the OSATS points (87/84; 54/55 points). Both groups improved in the mean time and points (1K: 52%, 77% 2K: 50%, 70%) as well, but there was no significant difference between them. In the case of new exercises on the last day, there was no difference between mean time (1K: 425 s, 2K: 411 s) and points (53/59 and 56/52), but there was a significant difference considering the points given for bimanuality., Conclusion: Based on our study, we cannot exactly state that the bimanuality needed for expert laparoscopic surgery would be easier to learn with immediately practising with both hands.

Medication-overuse headache affects 1 to 2 percent of the population. Any kind of painkiller, if taken regularly at least 10 days per month can cause medication-overuse headache, and therefore the possibility of this headache has to be raised whenever a patient with a preexistent headache notices a significant increase in headache frequency during a period of frequent painkiller consumption. Medication-overuse headache is most prevalent in females between 40 and 50 years of age. Its main risk factors are smokig, obesity, depression, and anxiety. The pathomechanism of medication-overuse headache is complex, with a probable genetic propensity and other biological (neurochemical and neurophysiological), as well as psychological and behavioural factors (such as anticipatory anxiety, catastrophisation of pain and consequentially a compulsive painkiller use) contributing to its genesis. The prerequisite of successful treatment is the withdrawal of the overused substance, other necessary elements of the therapy include the treatment of withdrawal symptoms including rebound headache, the introduction of an effective preventative therapy, taking into consideration the highly prevalent comorbid disorders as well, and the education and psychological support of patients. As the relapse rate can be as high as 30 to 40% regardless of effective treatment, the prevention of medication-overuse headache is of paramount importance, and the role of general practitioners can hardly be overstated.

Background: Migraine affects more than 10% of the Hungarian population, causes significant disability and severely affects patients' generic and condition-specific quality of life. Despite these facts, a significant proportion of patients is not diagnosed and not treated adequately. Headache centres can provide care for only a fraction of all patients. The task of primary care providers would be greatly simplified by a reliable self-administered migraine screening questionnaire., Objective: To develop a short and reliable questionnaire as a migraine screening tool., Methods: Outpatients at the Headache Service, Department of Neurology, Semmelweis University completed a self-administered questionnaire which contained 9 yes/no questions about their headaches' characteristics. The number of 'yes' answers (the patients' total score) was evaluated in connection with the diagnosis based on the International Headache Society criteria. We calculated the sensitivity, specificity, positive and negative predictive value as well as the misclassification rate for each total score value and used these to establish the final cutoff value of the questionnaire. 306 patients (242 females, mean age 39.1 ± 13.3 years) were enrolled. The diagnosis was migraine in 244., Results: Completing the questionnaire did not pose any difficulty for the patients. At a cutoff value of 5 points the questionnaire's sensitivity was 0.96 and specificity was 0.61. The positive predictive value was 0.91 and the negative pre- dictive value was 0.81. The misclassification rate was 0.11., Discussion: Our results show that the questionnaire may help the diagnosis of migraine. In order to use it in medical practice, its further evaluation is necessary on a large representative sample of the Hungarian population.
