Anti-N-methyl-D-aspartate receptor NMDA-R encephalitis is caused by antibodies against the NMDA-R and characterized by a severe encephalopathy with psychosis, epileptic seizures and autonomic disturbances. This disorder is often accompanied with malignancies, especially ovarian teratoma. Some patients’ EEGs show a different pattern similar to the waveforms of premature infants and this pattern is specifically named as extreme delta brush (EDB). We report a 24-year-old female having anti-NMDA receptor encephalitis and EDB patern.

[Molecular pathology of meningiomas]


[Meningiomas represent nearly one-third of all adult primary brain tumours. According to their clinical and histologic appearance, they can be divided into WHO grades I-III. Almost 90% of meningiomas are benign, showing favourable response to conventional therapies, however, patients diagnosed with grade 2 and 3 tumours may have a poor prognosis. In addition, high frequency of tumour recurrence renders treatments more challenging even in benign meningiomas. Molecular-pathological profiling of meningiomas could lead to development of more effective therapies. Although the cytogenetic background of these tumours are already wellcharacterised, the majority of related genes and mutations is still unknown. Recently, high-throughput techniques enabled better characterisation of mechanisms involved in meningioma development, progression and recurrence. Furthermore, epigenetic dysregulation could offer new opportunities for both diagnosis and treatment of meningiomas. We provide a comprehensive overview of cytogenetic and molecular genetic defects as well as epigenetic alterations in meningiomas. Many of these may serve as biomarker or therapeutic target in the near future.]

[High prevalence of burnout and depression may increase the incidence of comorbidities among Hungarian nurses]

ÁDÁM Szilvia, CSERHÁTI Zoltán, MÉSZÁROS Veronika

[Background and purpose - Poor mental health among health care professionals may have a significant impact on public health. There is limited information about the prevalence and potential consequences of burnout and depression among nurses in Hungary. The objective of this study is to explore the relationship between burnout as well as depression and somatic symptoms as well as comorbidities among nurses in Hungary. Methods - Cross-sectional study with self-administered questionnaires among 1,713 nurses. Burnout and depression were assessed by the Maslach Burnout Inventory (MBIHSS) and the Shortened Beck Depression Questionnaire, respectively. Somatisation was measured by the Patient Health Questionnaire (PHQ-15). Correlates of burnout and depression were assessed by logistic and linear regression analyses. Results - The prevalence of depressive symptom and clinical depression was 35% and 13%, respectively. The prevalence of moderate and high level emotional exhaustion, depersonalisation, and decreased personal accomplishment was 44%, 36% and 74%, respectively. We identified burnout and depression as a predictor of high prevalence of subjective somatisation. Whilst burnout showed a strong association with increased prevalence of hypertension, depression predicted almost all examined diseases, in particular, cardiac and cerebrovascular diseases, as well as neoplasms. Conclusion - We found high prevalence of burnout and depression among nurses in Hungary. As depression has been shown to be associated with higher prevalence of comorbidities than burnout, its consequences may be more significant. Appropriate prevention, diagnosis, and adequate treatment of burnout and depression may decrease the prevalence of ensuing comorbidities.]

Turkish version Quality of Life in Essential Tremor Questionnaire (QUEST): Validity and reliability study

GULER Sibel, TURAN F. Nesrin

Background - Our aim was to translate the Quality of Life in Essential Tremor Questionnaire (QUEST) advanced by Troster (2005) and to analyse the validity and reliability of this questionnaire. Methods - Two hundred twelve consecutive patients with essential tremor (ET) and forty-three control subjects were included in the study. Permission for the translation and validation of the QUEST scale was obtained. The translation was performed according to the guidelines provided by the publisher. After the translation, the final version of the scale was administered to both groups to determine its reliability and validity. Results - The QUEST Physical, Psychosocial, communication, Hobbies/leisure and Work/finance scores were 0.967, 0.968, 0.933, 0.964 and 0.925, respectively. There were good correlations between each of the QUEST scores that were indicative of good internal consistency. Additionally, we observed that all of the QUEST scores were most strongly related to the right and left arms (p=0.0001). However, we observed that all of the QUEST scores were weakly related to the voice, head and right leg (p=0.0001). Discussion - These findings support the notion that the Turkish version of the Quality of Life in Essential Tremor (QUEST) questionnaire is a valid and reliable tool for the assessment of the quality of life of patients with ET.

Anxiety management and functional magnetic resonance imaging - should it be a priority?

VANDULEK Csaba, DONKÓ Tamás, ILLÉS Anikó, EMRI Miklós, OPPOSITS Gábor, REPA Imre, KOVÁCS Árpád

Background and purpose - Studies have shown that a high proportion of patients undergoing MRI examinations experience anxiety and distress which may compromise image quality and successful data acquisition. Research on fMRI related anxiety is limited as to date, therefore, the purpose of this study was to assess the changes in anxiety as well as to examine its interactions with the implementation of a dedicated patient preparation phase prior to the examination. Methods - An fMRI examination consisting of six paradigms was performed on nine female and nine male healthy volunteers. Prior to the examination, the volunteers were subject to an extensive patient preparation phase including the professional support of a psychologist. The volunteers were subject to the State Trait Anxiety Inventory (STAI) pre and post fMRI. Blood pressure and heart rate were also measured pre and post fMRI examination. Results - A high level of trait and state anxiety was observed (STAI-T: 41.67±8.96; STAI-S: 34.78±9.79) prior to the examination. The level of state anxiety decreased significantly following the examination (STAI-S: 28.83±4.99, p<0.01). Correlation between the volunteers level of anxiety prior to the fMRI scan and the volume of the activation areas was observed in the finger-tapping (r=0.656; 0.561) and word generation (r=0.471) paradigms. Conclusion - The results of this study support the contribution of a supportive patient preparation phase inclusive of professional guidance to help reduce the volunteers’ level of distress and anxiety. These results encourage the study to be extended to clinical patients.

Quality of life of patients with non-diabetic peripheral neuropathic pain; results from a cross-sectional survey in general practices in Hungary


Background and purpose - There is a lack of data on the impact on health related quality of life of peripheral neuropathic pain in Hungary. The main aims of the study were to assess the health related quality of life of nondiabetic PeNP patients identified in general practices through screening, and to assess the relationship between condition specific pain scores and health state utilities. Methods - Non-diabetic patients aged ≥30 years were recruited in 10 general practices in Hungary. At first, patients filled in the PainDETECT Questionnaire (PD-Q) and those who have achieved ≥13 PD-Q score (unclear or possible neuropathic pain) were further assessed by the DN4 questionnaire. Patients with PD-Q score >18 or DN4 score ≥4 were considered to have PeNP and they completed the EQ-5D health questionnaire. Results - Among the 111 patients identified as non-diabetic PeNP patients the mean age was 62 (SD=14) years, 69% were women. Average EQ-5D score was 44% lower than the gender and age matched Hungarian norm (0.42 vs. 0.75, p<0.001) and it worsened with increasing pain intensity. The pain/discomfort and anxiety/depression were the most affected EQ-5D dimensions. Strong relationship was demonstrated between the PD-Q and EQ- 5D score. Most of the PeNP patients (86%) were undiagnosed. Conclusions - Non-diabetic PeNP pain has a huge negative impact on health related quality of life. Although PeNP is a serious chronic condition, the disease burden is seriously underestimated, both on the level of individuals and society, due to the fact that patients are rarely identified.

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

[Changing tendencies in retinal surgery]


[Retinal detachment, a disease caused by pathologic alteration of the vitreoretinal relationship, may decrease vision to blindness without treatment. Although some of the patients with retinal detachment become blind for the time being, last two decades produced significant improvement both in diagnosis and treatment. As a result of new surgical techniques we can perform successful surgery even in cases that were earlier inoperable. Recent methods are significantly less traumatic to the eye than they were 20 years ago. Dramatically reduced bedrest before and after surgery, regional or even topical anaesthesia instead of general anaesthesia, short term hospitalisation or one day surgery, short term restriction of physical activity after surgery are the most important consequences of the new wave of retinal detachment repair. According to recent recommendations of the prophylactic treatment of peripheral retinal lesions we treat only horse tears with sudden retinal complaints.]

[The relevancy of measuring the level of D-dimer test in clinical practice]


[Plasma levels of D-dimer may rise in a number of pathological conditions, which might be relevant for diagnosis as well as for prognosis. Its concentration increases with age, perhaps because of the wide-spread co-morbidity. In this article we demonstrate the diagnostic role of Ddimer in the well-known thromboembolic diseases. Beyond that, we highlight the importance of measuring D-dimer levels in other, lesser-known conditions, about which important findings have been published, such as cardiovascular, inflammatory or malignant diseases. It seems that in these disorders - provided that appropriate clinical conditions are available -, measuring D-dimer levels might have a role not only in diagnosis but in the prognosis as well. Furthermore, our aim was to discourage inappropriate clinical practice. Ignoring to measure the D-dimer levels (for fear of it being high) might lead to diagnostic errors. On the other hand, routinely performing the D-dimer test without clinical consideration (in the hope of it being negative) might cause diagnostic confusion in case of unexpected positivity and - mostly because of false interpretation - lead to further, unnecessary examinations.]

[Prognosis and classification of hypertensive striatocapsular haemorrhages]


[Introduction - Nontraumatic intracerebral haemorrhage accounts for 10 to 15% of all cases of stroke. Patients and method - In our study hypertensive striatocapsular haemorrhages were divided into six types on the basis of arterial territories: posterolateral, lateral, posteromedial, middle, anterior and massive (where the origin of the hemorrhage can not be defined due to the extensive damage of the striatocapsular region) type. We analysed laboratory data, clinical presentations and risk factors as alcoholism, smoking and hypertension of 111 cases. The size of the hematoma, midline shift and severity of ventricular propagation were measured on the acute CT-scan. The effect on the 30-day clinical outcome of these parameters were examined Results and conclusion - According to our results, the most important risk factor of hypertensive intracerebral haemorrhage was chronic alcoholism. Blood cholesterol, triglyceride levels and coagulation status had no effect on the prognosis, but high blood glucose levels Significantly worsen the clinical outcome. In our study, lateral striatocapsular haemorrhage was the most common while middle one was the least common type. The overall mortality is 42%, but differs by the type. The 30-day outcome significantly depends on the type of the haemorrhage, the initial level of consiousness, the size of the haematoma, the severity of ventricular propagation, the midline shift and the blood glucose levels. The clinical outcome proved to be the best in the anterior type, good in the posteromedial and lateral types. The prognosis of the massive type is poor. In our study, the classes and the mortality of the striatocapsular haemorrhages was different from the literature data. The higher mortality in our cohort could be due to the longer follow-up and the severe accompanying diseases of our patients.]

[The future in danger: a survey of the changes in the number of neurologists and a prognosis for 2010 in Hungary]

BERECZKI Dániel, CSIBA László, KOMOLY Sámuel, VÉCSEI László

[Lack of neurologists has become an obvious problem recently in Hungary, not only in small hospitals, but in major health care centers and also in university hospitals. With the current survey we set forth to estimate the number of board certified neurologists, and to evaluate the foreseeable changes in the next decade. In the beginning of 2010 there were 1310 physicians in Hungary with an official license to practice neurology. During 2009 neurological performance at least once during the year was claimed to the National Health Insurance Fund by 948 board certified neurologists. The number of those neurologists who are routinely involved in neurological patient care was estimated to be around 750. The lack of the young generation is characteristic for the age distribution of neurologists. In nine out of the 19 counties of Hungary the number of neurologists below the age of 35 is one or nil. In the ten-year period of 2000-2009 the annual mean number of new board certifications in neurology was 22. This number is much lower than that needed to replace those who get employed abroad and who leave the system for other reasons. The number of neurologists in the age range of 40-60 years will drop to 2/3 of the current number by 2020 even if emigration of neurologists will completely halt. If emigration will continue at the current rate and the number of those in neurological training will not increase considerably, then by 2020 only about 300 neurologists will have to cover neurological services throughout Hungary. As this number is insufficient for the task, and the tendency is clearly foreseeable, the health care government should urgently react to this situation to ensure an acceptable level of neurological services in the near future for the population of Hungary.]
