[INTRODUCTION - The loss in quality of life caused by mental illnesses has been growing in developed countries. This study aims to quantify the possible gains in quality of life by advantages of cariprazine therapy while treating patients with negative symptoms of schizophrenia in Hungary. Comparator therapy was defined as the currently available second-generation oral antipsychotic drugs. METHODS - In order to estimate the reachable gain in quality of life with cariprazine, an 8-state deterministic Markov cohort model was developed. Data was gathered from relevant scientific literature and public databases. The main assumptions regarding patient pathways have been validated by clinical experts, based on their real-life experience. The number of patients with negative symptoms of schizophrenia was estimated by the same methods as well. Sensitivity analyses were conducted on the input parameters. RESULTS - When compared with currently available second-generation oral antipsychotics, cariprazine generated an estimated increase of 0.05 quality-adjusted life years per patient in 2 years run. The deterministic sensitivity analysis confirmed the robustness of the results. Based on data of the National Health Insurance Fund and the scientific literature, a total gain of 450 quality-adjusted life years is expected at national level over a time horizon of 2 years. Even higher gains of QALY can be expected for longer time horizons. CONCLUSION - Based on conservative estimates significant health gain can be ge­ne­rated, if all patients with negative symp­toms of schizophrenia would receive the adequate cariprazine therapy in Hungary in­stead of the currently used se­cond-ge­ne­ration oral antipsychotic drugs. ]

[Experiences with the Hungarian version of the Sexual Risk Behavior Beliefs and Self-efficacy Scales ]

EÖRSI Dániel, CZEGLÉDI Edit

[INTRODUCTION - One of the most em­phasized areas of school health education is sexual safety. For risk reduction, adolescent’s beliefs and self-efficacy about sexual safety are decisive; however, no Hungarian measurement tool for this construction was available before. The aims of the present study were to adapt the Sexual Risk Behavior Beliefs and Self-efficacy Scales (SRBBS) to Hungarian, to explore the gender differences, and to assess predictors of condom use among high school students. METHOD - 9th and 10th class high school students in a north-Hungarian city were involved in our cross-sectional study (N = 649; 52.5% boys; mean age: 16.7 years; SD = 1.01 years). Measures: SRBBS questionnaire, sexual behavior issues. RESULTS - The psychometric analysis of SRBBS has yielded encouraging results. The theoretical factor structure is largely supported, the internal consistency of the scales is adequate and its test-retest reliability is mostly acceptable. 35.5% of the participants had sexual intercourse during their lifetime and 65.8% had used condoms at the last occasion. The boys (OR = 2.17, p = 0.021) and those who had more positive attitude towards condom use (OR = 1.24, p = 0.002) were significantly more likely to use a condom during the last act than girls, and subjects with less favorable attitude towards condom use. CONCLUSIONS - SRBBS questionnaire should be introduced into domestic research to measure the effectiveness of health check-ups and school health education programs. ]

[Medical therapy of peripherial artery disease]

BENCZÚR Béla

[Care of PAD (peripherial arterial disease) is one of the most negligent area of cardiovascular diseases: on one hand patients suffering from PAD are the most uncared, less educated and health-minded population (it’s enough to keep in mind the high rate of smoking and alcohol-abuse among them) in addition the number of angiologists is insufficient for the treatment of PAD. Although detection of PAD would be easy as a widely applicable, cheap screening method, the ankle-brachial index is available which is an obligatory screening investigation in general care. Therapeutic options are better and better since cilostazol was launched we have an evidence-based treatment which can solve the symptoms, slower the progression which is strongly recommended (IA recommendation) in both American and Hungarian guidelines. Cilostazol, a PDE3-inhibitor has complex pharmacological effect but contraindicated in several clinical conditions as pentoxiphylline is not totally excluded from the therapeutic arsenal of PAD. The place of antiplatelet agents is well-defined in the most recent European guidelines in the treatment of PAD. The jumping development of interventional radiology beyond medical therapy contributed a lot to prevent limb amputations in the case of early detection of PAD. ]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]

VÁLYI Péter

[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.
