[Objective - To survey the role of pattern electroretinography (PERG) and pattern visual evoked potentials (VEPs) in the process of clinical evaluation of neuro-ophthalmological cases. The study is illustrated with the electrophysiological findings of 231 patients sent to our laboratory in 2005 because of the suspicion of damage in the optic pathway. Methods - The RETIport program of the ROLAND equipment (Wiesbaden - Germany) was used to record PERGs and VEPs. The recordings were done according to the recommendations of the International Society for Clinical Electrophysiology of Vision. Results - The combined application of PERG and VEP provided useful data on the retino-cortical conduction time and hence demyelinisation. The comparison of the N35/P50 and P50/N90 amplitudes of the PERG recordings greatly promoted the diagnostic procedure. Conclusions - The combined application of PERG and VEP methods is recommended in the assessment of optic nerve function of neuro-ophthalmological patients.]

[THE USE OF STALEVO IN HUNGARY. AN OBSERVATIONAL STUDY]

KLIVÉNYI Péter, VÉCSEI László

[The triple combination of levodopa, DDCI and entacapone (Stalevo) is used to treat motor complication in Parkinsonian patients with fluctuation. An observational investigation has been conducted in Hungary to study the effects of Stalevo on the “wearing off” phenomenon and on the quality of life in patients, who are to be treated with. The introduction of Stalevo to the treatment resulted in no changes in the number of patients taking selegiline, amantadine and dopamin agonists, while the number of patients taking anticholinergic drugs were slightly increased. This treatment significantly decreased the average Hoehn-Yahr stadium, as well as the non-motor symptoms, without any remarkable side effect. Stalevo also improved the quality of life, detected by the EQ-5D questionare and the visual analoge scale.]

[Deep brain stimulation is a widely used technique for the treatment of movement disorders. This method is a breakthrough in treatment of drug-resistant idiopathic Parkinson’s disease, essential tremor and dystonia. The aim of the present paper is to give an inside overview of the postoperative management like fine tuning of the stimulation and balancing the antiparkinsonian medication. We also discuss the advantage of the use of the (Access Therapy) patient controller. After reviewing the stimulation-related side-effects and their management, the contraindicated medical procedures are discussed.]

[Occlusive hydrocephalus caused by a fourth ventricle arachnoid cyst (in English language)]

[The case history of a woman with occlusive hydrocephalus caused by a fourth ventricle cyst is presented. She had slowly progressive complaints and symptoms - concentration and memory disturbances, low-tempered mood, then slight dizziness, loss of appetite and progressive headache - transitorily misinterpreted for signs of depression. She had been treated by psychotherapy and antidepressants for months. Since she did not improve she was referred to a psychiatric hospital. The rapidly progressing neurological syndrome with worsening headache, gait disturbance and vomiting was finally identified and it turned out to be caused by a fourth ventricle CSF blockage of unknown aetiology. An acute neurosurgical intervention was indicated. It revealed a huge fourth ventricle cyst, undetectable on MRI, occupying the whole ventricle. The resection of its walls resulted in complete recovery. We conclude that since unspecific mental complaints and symptoms suggesting depression may be misleading, their organic origin has to be excluded.]

[New chapter in visual evoked potential studies - Clinical application of the multifocal vep method ]

JANÁKY Márta, PÁLFFY Andrea, BENEDEK Krisztina, BENEDEK György

[The multifocal visual evoked potentials are the evoked responses over the visual cortex in response to the stimulation of circumscribed small areas in the central 30 degree region of the retina. The recording of multifocal visual evoked potentials was made possible by the computer algorhythm elaborated by Sutter in 1991. Multifocal electroretinograpy, developed upon the same theoretical principles, is already an routine clinical examination method for the topographic analysis of functional damages in the central part of the retina and for the differential diagnostics in neuro-ophthalmology. The multifocal visual evoked potential, however, has not been introduced into the clinical practice, although it displays the function of ganglion cells in a given region of the retina in a more detailed way than the sensitivity threshold in the perimetry. This examination makes the objective verification of defects possible in the visual pathway, too. In our department the recording of multifocal visual evoked potentials was started in 2002. In this paper we present the basics of this method and also deal with the problems concerning its application and its status in the history of visual evoked potentials.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

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.]
