[Effects of maternal epilepsy and antiepileptic therapy in women during pregnancy]

VANYA Melinda, ÁRVA-NAGY Nóra, SZILI Károly, SZOK Délia, BÁRTFAI György

[Objective - The aim of this study was to analyse the effects of epilepsy and antiepileptic drug (AED) treatment on pregnancy and the perinatal outcome, retrospectively. Methods - We examined the obstetric and fetal outcomes among women with epilepsy (WWE), who were followed-up at the Department of Neurology, and who delivered at the Department of Obstetrics and Gynaecology (n=91) between 31th December 2000 and 31th March 2014. Statistical comparisons of different obstetric and fetal parameters on a sample of 91 WWE and 182 non-WWE were assessed by the chi-square-test, the independent sample t-test. Results - The rate of major congenital malformations (MCMS) among the newborns of all AEDs exposed mothers was 7.69%. There were three peaks of seizures: during the third trimester, during delivery and in the puerperium. The prevalence of miscarriages, post-term birth and the rate of caesarean section were significantly higher among the WWE than among the non-WWE (p=0.001; p<0.001; p=0.02). Parameters of neonates (birth weight, birth length, head-, and chest circumference) were significantly different between the WWE group and the non-WWE group (p=0.003, p<0.001, p<0.001, p<0.001) Conclusions - In contrast with recent publications, there were significant differences in the parameters of neonates between the two groups. Our results are in accordance with those of previous studies from the aspect of AED-related MCM, the elevated risk of miscarriages and pre-existing hypertension. ]

[Shifting function of working memory in psychotic disorders]

DOMJÁN Nóra, GREMINGER Nóra, DRÓTOS Gergely, JANKA Zoltán, SZENDI István

[Background and aims - Mental disorders with psychotic features are overlapping in many ways and there are a growing number of comparative studies in the last decades regarding this. Cognitive deficit is well underpinned in schizophrenia, but fewer studies are conducted in this area including patients with bipolar affective disorder. Therefore the aim of the present study was to investigate the cognitive performance of these two patient groups and healthy controls. The Wisconsin Card Sorting Task is a very sensitive measure of the shifting function. Schizophrenic patients perform consistently poorer on this task than healthy controls, while there are not much data about individuals with bipolar affective disorder. Methods - The Wisconsin Card Sorting Task and clinical symptom rating scales were administered to 26 patients with schizophrenia, 24 with bipolar affective disorder and 21 healthy controls. Results - Significant differences were found among the performance of the three groups using four different dimensions of the Wisconsin Card Sorting Task. The schizophrenic group made more perseverative errors and achieved less conceptual level responses and completed fewer categories compared to healthy controls. Patients with schizophrenia were able to complete fewer categories and had fewer conceptual level responses than the bipolar group. No significant differences were observed between patients with bipolar disorder and healthy controls. Conclusions - According to these results, patients with schizophrenia and bipolar affective disorder showed no similarities on the Wisconsin Card Sorting Task. Bipolar patients performed the task on the same level as healthy individuals did. The two mental disorders influence cognitive performance differently.]

[Measuring of functional impairment of lumbal spine]

VALASEK Tamás, VARGA Péter Pál, KLEMENCSICS István, SZÖVÉRFI Zsolt, BOZSÓDI Árpád, ÉLTES Péter Endre, LAZÁRY Áron

[Background and purpose - The purpose of our study was to outline the Hungarian validation process of the Oswestry Disability Index, the Quebec Back Pain Disability Scale, the Roland-Morris Disability Questionnaire and the Core Outcome Measurement Index, as well as to draw up recommendations regarding their future applications. Methods - The Hungarian versions were brought to life after a cultural and linguistic adaptation. Next to the above-mentioned questionnaires, the questionnaire booklet used for validation also contained the WHOQoL-BREF general quality of life questionnaire and a pain measuring Visual Analog Scale. The data of low-back pain patients were registered twice in two weeks. We determined the internal homogeneity (Cronbach alpha), reproducibility, standard error of measurement and the minimal detectable change of the questionnaires. Patients were assigned into different two subgroups (surgical / non-surgical, with / without affection of nerve roots) and differences between the subgroups were examined with the help of the questionnaires. We determined the physical subscale of the WHOQoL-BREF and the correlation between the pain and the studied questionnaires. Results - The value of Cronbach alpha was between 0.85 and 0.95. All four questionnaires showed significant differences (p<0.001) between the subgroups. The correlation studies brought strong and significant results (p<0.001, r>0.5) in every case. The values of reproducibility were between 0.93-0.92. The results of standard measurement error: 4.8 (Oswestry), 5.2 (Quebec), 1.6 (Roland-Morris), 0.59 (Core Index). The minimal detectable change was 13; 14; 4, and 2 points, respectively. Conclusion - The Hungarian versions of all four questionnaires are valid. They can be applied with scientific certainty to measure low back pain patients. From the studied questionnaires, we especially recommend the wide-raging application of the Oswestry Disability Index and the Core Outcome Measurement Index based on their psychometric and application features. ]

[Proconvulsive effect of antiepileptic drugs]

KELEMEN Anna

[Antiepileptic drugs can provoke and worsen seizures, what is called paradoxical effect. Paradoxical seizure worsening can occur as a nonspecific manifestation of drug intoxication in number of antiepileptic drugs. The other type is a specific type, when antiepileptic drugs with pure GABAergic and sodium channel blocker mechanism of action provoke myoclonic, absence and atonic seizures in specific epilepsy syndromes, mainly in idiopathic generalized epilepsies. Antiepileptic drug-induced exacerbation of seizures is a common, often unrecognized clinical problem, which can be avoided by a careful syndromic diagnosis and by using broad spectrum antiepileptic drugs.]

[Do previous offences predict violent acts in psychiatric patients? A retrospective study in Hungary]

BARAN Brigitta, SZABÓ Ádám Ferenc, KARA Borbála, KOVÁCS Magdolna, UZONYI Adél, ANTAL Albert, UNGVARI S Gabor, GAZDAG Gábor

[Aim - To investigate the presence of offences in the previous past history of perpetrators of violent acts who have undergone forced medical treatment. Methods - The documentation of all patients released over a 10-year period from the National Institute of Forensic Psychiatry (IMEI) was reviewed. A comparison was drawn between patients who were convicted of any type of offense before the violent act (patients with previous offences-PPO) and those who were not (patients with no previous offences-PNO). Results - Eighty-six (29%) and 208 (71%) patients formed the PPO and PNO groups, respectively. Prior contact with psychiatric services was significantly higher in the PPO group (p=0.038) and this group was also more likely to offend under the influence of a psychoactive substance (p<0.001). Exceptional brutality and other qualifying factors were more frequent in the PNO group (p=0.019). Conclusion - As IMEI is the only forensic institution in Hungary, the picture presented here reflects the situation in the entire country. A recidivism rate of 29% is within the internationally published range. ]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[LADA type diabetes, celiac diasease, cerebellar ataxia and stiff person syndrome. A rare association of autoimmune disorders]

SOÓS Zsuzsanna, SALAMON Mónika, ERDEI Katalin, KASZÁS Nóra, FOLYOVICH András, SZŰCS Anna, BARCS Gábor, ARÁNYI Zsuzsanna, SKALICZKI József, VADASDI Károly, WINKLER Gábor

[Celiac disease - in its typical form - is a chronic immunemediated enteropathy with typical clinical symptoms that develops against gliadin content of cereal grains, and is often associated with other autoimmune diseases. In cases of atypical manifestation classic symptoms may be absent or mild, and extra-intestinal symptoms or associated syndromes dominate clinical picture. The authors present a longitudinal follow-up of such a case. A 63-years old woman was diagnosed with epilepsy at the age of 19, and with progressive limb ataxia at the age of 36, which was initially thought to be caused by cerebellar atrophy, later probably by stiff person syndrome. At the age 59, her diabetes mellitus manifested with type 2 diabetic phenotype, but based on GAD positivity later was reclassified as type 1 diabetes. Only the last check-up discovered the celiac disease, retrospectively explaining the entire disease course and neurological symptoms. By presenting this case, the authors would like to draw attention to the fact that one should think of the possibility of celiac disease when cerebellar ataxia, progressive neurological symptoms and diabetes are present at the same time. An early diagnosis may help to delay the progression of disease and help better treatment.]

[Acoustic CR®-neuromodulation - first experiencies in Hungary with novel patented method in therapy of chronic subjectiv tinnitus]

BENCSIK Beáta, GÁBORJÁN Anita, HARNOS Andrea, LÁSZLÓ Klára, VÉGSŐ Péter, TAMÁS László

[Objective - Acoustic CR®-neuromodulation is a novel patented method for the therapy of chronic subjective tinnitus and has been tested in Hungary, as one of the first European countries introducing this procedure. It can be used for the treatment of monaural or binaural tonal tinnitus. Suitability of patients for this therapy was assessed by the help of an appropriate set of criteria. Aim of our study was to analyze 6-month therapy and related measurement data of patients first treated with this method in Hungary and evaluate the results. Method - 27 outpatients (20 males, seven females) with a minimum of 6-month long history of subjective tinnitus were assessed (four detected on the right side, six on the left side, 17 on both sides) who were treated for six months by Acoustic CR®-neuromodulation. On 44 treated ears (21 right, 23 left), changes of tinnitus frequency and loudness were measured and analysed, using Visual Analogue Scale (VAS) loudness/annoyance/pitch scores and Tinnitus Handicap Inventory tests, which were performed at defined intervals during the treatment period. Results - During this 6-month treatment period, significant decrease was detected in tinnitus frequency and loudness by tinnitometry (irrespective of the affected side), and an improvement in VAS annoyance/pitch scores and THI test results. VAS loudness did not show any significant changes. Conclusion - Acoustic CR®-neuromodulation therapy may be a useful treatment of subjective chronic tinnitus, but its efficacy should be proved in controlled clinical trials.]

[The examination of the factors which are the underlying causes of the intrauterine fetal death]

ZUBOR Mónika, SZABÓ László, KARÁCSONY Ilona Hajnalka

[The aim of the study: Nowadays the most common obstetric complication is the stillbirth. The affected families suffer spiritually as well. The aim of our research was to identify those most common maternal factors which lead to the intrauterine death of the fetus. Material and methods: The retrospective research was carried out between January of 2007 and December of 2014 in Markusovszky Educational Hospital in Szombathely. During the non-random, targeted sampling, the research was carried out with the help of an essay which included the data of 50 people. Beside the descriptive statistics the authors also used Chi-squared test with the help of the Microsoft Excel program (p<0,05). Results: If we take into account the frequency of stillbirth, there is significant relationship between singular pregnancies and twin pregnancies (p<0,05). Among women from different ages there is a significant relationship between the frequency of endocrine diseases and stillbirth as well (p<0,05). According to the results the most common cause of the intrauterine death was hypoxia (32,6%). Conclusion:With the identification of high risk pregnancies at an early age and with the prevention the complications we could reduce the number of stillbirths.]
