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.

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[Capability of stroke scales to detect large vessel occlusion in acute ischemic stroke – a pilot study ]

[Rapid changes of stroke management in recent years facilitate the need for accurate and easy-to-use screening methods for early detection of large vessel occlusion (LVO) in acute ischemic stroke (AIS). Our aim was to evaluate the ability of various stroke scales to discriminate an LVO in AIS. We have performed a cross-sectional, observational study based on a registry of consecutive patients with first ever AIS admitted up to 4.5 hours after symptom onset to a comprehensive stroke centre. The diagnostic capability of 14 stroke scales were investigated using receiver operating characteristic (ROC) analysis. Area under the curve (AUC) values of NIHSS, modified NIHSS, shortened NIHSS-EMS, sNIHSS-8, sNIHSS-5 and Rapid Arterial Occlusion Evaluation (RACE) scales were among the highest (>0.800 respectively). A total of 6 scales had cut-off values providing at least 80% specificity and 50% sensitivity, and 5 scales had cut-off values with at least 70% specificity and 75% sensitivity. Certain stroke scales may be suitable for discriminating an LVO in AIS. The NIHSS and modified NIHSS are primarily suitable for use in hospital settings. However, sNIHSS-EMS, sNIHSS-8, sNIHSS-5, RACE and 3-Item Stroke Scale (3I-SS) are easier to perform and interpret, hence their use may be more advantageous in the prehospital setting. Prospective (prehospital) validation of these scales could be the scope of future studies.]

[Prevalence and treatment of hypertension in patients with newly diagnosed familial hypercholesterolemia]

[Familial hypercholesterolemia (FH) is an inherited defect of cholesterol metabolism characterized by high plasma total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels and premature cardiovascular disease risk. Prevalence of hypertension in FH is not clarified, but its appearance is independent risk factor for the development of cardiovascular disease. Therefore, optimal treatment has a major priority in this high-risk population. We aimed to investigate the lipid parameters and evaluate the presence of hypertension and its treatment characteristics in 86 newly diagnosed, untreated heterozygous FH patients (27 males, 59 females, mean age 53.6±13.4 years). We diagnosed FH by using the Dutch Lipid Clinic Network criteria. The mean TC level was 8.49±1.7 mmol/l, the mean LDL-C level was 6.11±1.5 mmol/l, the mean high-density lipoprotein cholesterol (HDL-C) level was 1.62±0.5 mmol/l, while the median lipoprotein (a) level was 301 mg/l. We diagnosed 33 FH patients (38.4%) with hypertension. Beta blockers were used in 23, ACE-inhibitors in 13, ARBs in 12, calcium channel blockers in 9, and HCT in 11 cases. 11 patients was treated with monotherapy, for 10 patients double, for 11 patients triple, while for 1 patient quadruple combined antihypertensive therapy was administered. Based on our results, hypertension might be underdiagnosed in this specific patient population. Neither the types nor the combination patterns of blood pressure lowering agents are in line with current guidelines. Up to date screening and treatment of hypertension should be worth considering in this extremely high risk population with enhanced atherosclerosis.]

[Aim - Eating disorders are becoming an increasingly relevant health issue, therefore the fast and accurate screening of people at risk is of great practical importance. The aim of SCOFF questionnaire is to assess this risk and the extent to which a person is affected, by using five simple yes or no questions. The objective of our study was to assess the validity of the Hungarian version of the test Methods - 777 medical students (210 men, 567 women, mean age 22.3±2.33 years) participated in the survey. The online questionnaire contained anthropometric data, the Eating Behaviour Severity Scale and, beside the SCOFF, the Eating Disorder Inventory (EDI). Results - The SCOFF is excellent at screening clinical eating disorders. Its sensitivity was 100% and specificity 85.1%. It is less efficient at detecting subclinical cases, but it does not show worse results than EDI. According to the data SCOFF is better at identifying more serious cases. Applying on the same sample SCOFF had higher sensitivity and lower specificity than EDI. Discussion - SCOFF is suitable for primary screening of eating disorders with a non-diagnostic purpose, taken two “yes” answers out of five as the critical margin, specified by the authors.]
