[Objective - In our case report we present the treatment of a female patient suffering from therapy resistant depression. This procedure is not in practice in Hungary at present, the aim of our work to reproduce the findigs of international studies in domestic circumstances. Matter - Major depression is a common, chronic and severe mental disorder, with 16.2% lifetime prevalence. Many international randomized, placebo controlled trials found administration of ketamine infusion effective in depressed patients. Methods - Since ketamine is an anesthetic agent, its administration was performed in the post-operative monitoring room of our hospital operating-room, supervised by an anesthesiologist. According to formerly published data, a dose of 0.5 mg/kg of body weight was administered intravenously in 40 minutes by perfusor. The drug was administered in a same manner fifteen days later. Subject - The patient was admitted to our inpatient ward with severe depression. During two months of combined antidepressant therapy her condition has not improved significantly. Approval for off label drug indication was granted with urgency by the National Institute of Quality and Organizational Development in Healthcare and Medicines. Results - During the two treatments the Hamilton Depression Rating Scale 21 items rating scale score was reduced to 8 from the baseline 28, the Hamilton Anxiety Rating Scale score was reduced to 6 from 25, Beck Depression Inventory was reduced to 9 from 20. Upon administration of the drug no severe adverse event was detected, the mild dissociative state related to ketamine was ceased in a short period of time. Discussion - With administration of 0.5 mg/kg ketamine the authors managed to achieve rapid improvement in a therapy resistant depressed patient, without permanent side effects. Our future plan is to repeat the use of the drug within a double-blind, placebo controlled trial in order to prove its efficacy in hospital settings. ]

[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. ]

How to minimize the risk for headache? A lumbar puncture practice questionnaire study

JONATAN Salzer, RAJDA Cecilia, SUNDSTRÖM Peter, MATTIAS Vågberg, VÉCSEI László, ANDERS Svenningsson

Background - To lower the risk for post lumbar puncture (LP) headache the American Academy of Neurology (AAN) recommended using small bore atraumatic needles together with stylet reinsertion in a report from 2005. It is unclear whether these recommendations are followed or not. Objectives - To investigate the diagnostic LP preferences with respect to the AAN guidelines among neurologists by use of a short online questionnaire, and to review previously published literature on the subject. Results - A total of 284 respondents who performed diagnostic LPs completed the questionnaire. Almost half (41%) answered that they always use atraumatic needles. The most common reason (73%) for not using atraumatic needles was that these were not available. Less than half of the respondents who performed LPs had knowledge about the AAN guidelines for diagnostic LPs, and 48-76% agreed with the different recommendations therein. Five previously (1998-2015) published studies investigating LP practice among neurologists were identified. The reported frequency of atraumatic needle use (always/routinely) varied between 2 and 16%. Discussion - Atraumatic needle use was more common in this study compared with previous publications. There is still skepticism regarding some of the AAN recommendations, and needle availability appears to be the most important factor preventing atraumatic needle use. To increase the use of atraumatic needles we may perform additional studies investigating their potential benefits, and arrange training sessions for neurologists to increase their awareness and level of comfort with the atraumatic LP technique.

Unilateral thalamic infarction causing downward gaze palsy in a patient with uncorrected tetralogy of fallot: a case report

ANNUS Ádám, BENCSIK Krisztina, JÁRDÁNHÁZY Tamás, VÉCSEI László, KLIVÉNYI Péter

Introduction - Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease (CHD). Adults with surgically uncorrected forms of this condition are extremely rare, since operation is recommended in childhood to prevent cyanosis. Cyanotic CHD increases the risk of thromboembolic events. An endothelial dysfunction caused by chronic hypoxia and shear stress due to rheological alterations with a platelet dysfunction appear to be the explanation behind this finding. Paramedian thalamic infarction causing vertical gaze palsy without midbrain involvement is an infrequent finding. We report here a rare case of a patient with untreated TOF, who suffered a left-sided unilateral thalamic infarction presenting as downward gaze palsy and diplopia. Case presentation - A 44-year-old women complained of sudden onset diplopia and vertigo. Neurological examination revealed a downward gaze palsy with other symptoms related to a vertebrobasilar territory circulatory disturbance. The MRI scan revealed an acute infarction, 8 mm in diameter in the left medial thalamic region without midbrain involvement. Discussion - Adults with uncorrected forms of TOF are extremely uncommon, and descriptions of stroke in these patients are therefore rarities. We set out to give a concise survey of the literature regarding TOF patients with stroke. Conclusion - We present a rare case of unilateral thalamic infarction causing downward gaze palsy in an adult patient with uncorrected TOF. Cyanotic CHD is regarded as one of the risk factors of stroke. Besides other pathologic conditions, ischaemic stroke at an early age should raise the suspicion of a cardioembolic origin and, in rare cases, might result from cyanotic CHD.

Vitreous humor diffusion measurements from diffusionweighted imaging in idiopathic intracranial hypertension

CAGLI Bekir, TUNCEL Alpaslan Sedat, YILMAZ Erdem, TEKATAS Aslan, ERMIS Veli

Background - Idiopathic intracranial hypertension is a disease with uncertain etiology. It is not caused by an intracranial mass lesion or hydrocephalus and is characterized by abnormal elevation of intracranial pressure and normal composition of the cerebrospinal fluid. The orbita and intracranial area are closely related anatomically. Elevated intracranial pressure can be transmitted to the orbita through the cerebrospinal fluid around the optic nerve sheath changes at the vitreous humor on diffusion-weighted imaging have not been systemically studied in idiopathic intracranial hypertension. Purpose - The purpose of this study was to investigate diffusion changes in the vitreous humor in patients with intracranial hypertension. Methods - In this retrospective study, 25 patients with papilledema and who had been definitively diagnosed with idiopathic intracranial hypertension and 20 control participants were evaluated. Control subjects and patients were scanned with a 1.5 Tesla magnetic resonance imaging. Apparent diffusion coefficient maps were obtained from diffusion-weighted imaging with a b value of 1000 s/mm2 and apparent diffusion coefficient values were automatically calculated. These images were obtained by a radiologist who was blinded to the details of the study for center of each vitreous humor and the body of lateral ventricle. The mean apparent diffusion coefficient values of each vitreous humor and the body of the lateral ventricle were calculated for each group (control group and patients) and quantitative comparisons were performed. Results - There were no statistically significant differences in mean apparent diffusion coefficient values of the right vitreous humor, left vitreous humor and the body of the lateral ventricle between the patients with idiopathic intracranial hypertension and the control group (p=0.766, p=0.864, p=0.576, respectively). Discussion - Vitreous humor is a closed system and has no direct relationship with the cerebrospinal fluid or cerebral tissue and although morphological changes occur in the orbital structures, including the optic disk and optic nerve in idiopathic intracranial hypertension, the indirect effects of these changes on the vitreous humor may be too subtle to measure. Conclusion - We did not find a significant difference in the mean apparent diffusion coefficient value of the vitreous humor between the patients with idiopathic intracranial hypertension and the control group. However, future studies will be necessary to determine if changes in the vitreous humor can be used to diagnose intracranial hypertension.

Validation of the Hungarian PHQ-15. A latent variable approach

STAUDER Adrienne, WITTHÖFT Michael, KÖTELES Ferenc

Somatic symptoms without a clear-cut organic or biomedical background, also called “medically unexplained” or “somatoform” symptoms, are frequent in primary and secondary health care. They are often accompanied by depression and/or anxiety, and cause functional impairment. The Patient Health Question­naire Somatic Symptom Scale (PHQ-15) was developed to measure somatic symptom distress based on the frequency and bothersomeness of non-specific somatic symptoms. The study aimed to (1) evaluate the Hungarian version of the PHQ-15 from a psychometric point of view; (2) replicate the bifactor structure and associations with negative affect described in the literature; and (3) provide the Hungarian clinical and scientific community with reference (normal) values split by sex and age groups. PHQ-15, depression (BDI-R), and subjective well-being (WHO-5) scores obtained from a large (n = 5020) and close to representative community sample (Hun­garostudy 2006) were subjected to correlation analysis and linear structural equation modeling. The PHQ-15 showed good internal consistency (Cronbach’s α = 0.810; McDonald’s ω = 0.819) and moderate to strong correlation with the BDI-R (rs = .49, p < 0.001) and WHO-5 (rs = -.48, p < 0.001). Fit of the bifactor structure was excellent; in independent analyses, the general factor was strongly associated with depression (β = 0.656±0.017, p < 0.001) and well-being (β = -0.575±0.015, p < 0.001), whereas the symptom specific factors were only weakly or not related to these constructs. The PHQ-15 score was higher in females and showed a weak positive association with age. The Hungarian PHQ-15 is a psychometrically sound scale which is positively associated with depression and ne­gatively related to subjective well-being. The bifactor structure indicates the existence and meaningfulness of a gene­ral factor representing the affective-motivational component of somatic symptom distress. The Hungarian version of the PHQ-15 is a brief and usable tool for the pre-screening of somatization disorder (DSM-IV) or somatic symptom disorder (DSM-5). The reported reference values can be used in the future for both clinical and research purposes.

[Psychometric properties of the Hungarian Adult Attachment Scale]

ŐRI Dorottya, KAPORNAI Krisztina, BAJI Ildikó, KISS Enikő

[The revised Adult Attachment Scale (AAS) developed by N. L. Collins is a widely used questionnaire to measure adult attachment. However, its psychometric properties have not been investigated in Hungary. We aimed to confirm the key psychometric properties of the Hungarian version of the AAS focusing on reliability indices on a population that consis­ted of depressed and non-depressed young adults. The AAS is a self-report questionnaire, in which two different dimensional evaluating systems are possible: the original (close, depend, and anxiety) and the alternative scoring system (anxiety, avoidance). Our study population consisted of young adults with a history of major depression (n = 264, median age = 25.7 years) and their never-depressed biological siblings (n = 244, median age = 24.0). The internal consistency of close, anxiety, and avoidance scales were satisfactory (Cronbach-α >0.7). The consistency of the depend scale was slightly lower than expected (Cronbach-α = 0.62). Test-retest reliability was good for all of the scales, it ranged from 0.73 to 0.78 after 14 months of follow-up period. The scale showed good discrimination as tested by the differences of close and anxiety attachment dimensions between the groups (p<0.01). More­over, we were able to differentiate the currently dep­res­sed subjects based on these attachment dimensions. Explo­ra­tory and confirmatory factor analyses were conducted, and a bifactor solution proved optimal model fit. The three dimensions of the AAS has not been confirmed. However, the close and anxiety scales of AAS were found to be adequate. Our results also indicate that attachment features correlate with major depressive episodes in adulthood.]

[The examination of burnout among healthcare workers]

FEJES Éva, MÁK Kornél, POHL Marietta, BANK Gyula, FEHÉR Gergely, TIBOLD Antal

[Health reforms in recent decades have been largely based on economic considerations and have led to a significant problem in the sector today, with the issue of human resources being pushed back, which is exacerbated by burnout syndrome. The aim of this questionnaire-based study was to examine the complex background of burnout among health care workers in the cities of Komló, Pécs and Kecskemét. Baseline demographic data were recorded. Burnout was assessed by the Maslach Burnout Inventory (MBI), and the intensity of dysfunctional attitudes were also studied. Depression was detected by the Beck Scale and social supports, and effort-reward dysbalance were also examined. Overall 411 employees participated in our study. Age group distribution was middle aged access, vast majority of the workers was between 36 and 55 years. Mean burnout scale was 58.6 (SD = 16.3), 63 workers had mild (14.2%), 356 had moderate (80.7%) and 22 had severe (5.1%) burnout. In a multivariate analysis the type of work (OR = 1.018), age (OR = 2.514), marital status (OR = 1.148), job type (OR = 1.246) the lack of social support (OR = 1.189) and allowance (OR = 9.719) were independently associated with burnout (p < 0.05 in all cases). There was a significant association among burnout, depression and dysfunctional attitudes. The vast majority of our social workers suffered from moderate and a small, but significant proportion suffered from severe burnout. Our work draws attention to the modifiable and unmodifiable risk factors of burnout in this population, which may help in the development of preventive strategies.]

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

[Diabetes, dementia, depression, distress]

SZATMÁRI Szabolcs, ORBÁN-KIS Károly, MIHÁLY István, LÁZÁR Alpár Sándor

[The number of people living with diabetes continues to rise. Therefore neurologists or other health care practitioners may be increasingly faced with comorbid neuropsychiatric disorders commonly presented by diabetic patients. More recently there has been an increasing research interest not only in the interactions between diabetes and the nervous system, the fine structure and functional changes of the brain, but also in the cognitive aspects of antidiabetic treatments. Patients with both types of diabetes mellitus may show signs of cognitive decline, and depression. Comorbid insomnia, anxiety, and distress may also occur. The bi-directional relationships between all these phenomena as well as their connection with diabetes can lead to further health and quality of life deterioration. Therefore it is important that all practitioners involved in the care of diabetic patients recognize the presence of comorbid neuropsychiatric disturbances early on during the healthcare process. Identifying higher risk patients and early screening could improve the prognosis of diabetes and may prevent complications.]
