[Hungary is among the countries with the highest rates of stroke mortality. Accuracy of data in international statistical reports have been crlticized by several authors. The aim of the present study was to give a methodological description of the database, to report basic patient characteristics and to discuss causes of discrepancies between national and hospital stroke morbidity and mortality data. Data from a stroke unit with a catchment area of 210 000 inhabitants were used to create a database from about 100 parameters per patient discharged from the stroke unit during a 12-month period. During this period 505 patients with acute stroke were treated at the stroke unit. Of the patients admitted 15% did not have stroke. Fatality among inpatients with acute stroke was 18.6% (n=94). Assuming that all stroke patients of the catchment area were treated at the stroke unit and that stroke mortality in the catchment area equals that of the national value, 410 deaths should have occurred at the unit. The discrepancy between the number of the expected and detected stroke fatality cases might imply that either a large number of stroke patients from the catchment area do not reach the stroke unit, or actual stroke mortality is lower in our region than the national average. To examine these hypotheses, a population based prospective study should be performed. ]

[Experiences of surgically treated temporal epileptic patients - multicentre study ]

BALOGH Atilla, BORBÉLY Katalin, CZIRJÁK Sándor, HALÁSZ Péter, JUHOS Vera, KENÉZ József, VAJDA János

[Our experiences on surgically treated temporal lobe epileptic patients are presented. Involved in the disease are the process of preoperative investigations, clinical data, types of operation and their indications, and the postoperative controls. Pre- and postoperative data of 36 surgically treated, intractable temporal lobe epileptic patients were analysed. A postoperative follow-up of longer than two years was carried out on 24 patients. The experiences of these patients on postoperative seizure frequency were evaluated using Engel's classification. Among these 24 temporal lobe epileptic patients 19 are seizure free (Engel I.), the seizure frequency significantly decreased in 3 of them (Engel II.), in the case of 2 patients the number of seizures was reduced (Engel III.). Our experiences show that neurosurgical investigation seems to be an increasingly useful, alternative way for treating intractable temporal lobe epileptic patients.]

[Lumbar pseudoradicular pain part 1: anatomical principles]

KASÓ Gábor, DÓCZI Tamás, DÁVID Károly

[Most low back and leg pain, caused by degenerative disorders of the lumbar spine can be classified as referred (projected) pain. One of the types of referred pain is pseudoradicular pain originating from the characteristics of innervation of the spinal motion segment. Ventral parts of the spinal motion segment are supplied by the sinuvertebral nerve and the sympathetic nervous system, while the dorsal compartment is innervated by dorsal rami of the spinal nerves and both systems show considerable segmental overlap]

VIDA Zsuzsanna, FOLYOVICH András, GÁCS Gyula

[Based on five cases a description is given n-hexane induced polyneuropathy caused by laundry cleaning gasoline, a kind of exposition that has not been published up till now. The symptoms (subacute sensomotor polyneuropathy) and the peculiar course (further deterioration after the exposition has ceased) of hexacarbon polyneuropathy caused by gasoline were similar to that of other cases induced by other n-hexane containing materials such as diluting agents, glues, lacquers etc.]

[Short- term video EEG analysis in a useful tool in the diagnosis of epileptic phenomena]


[Short-term (30–120 min) video- EEG recording and split-screen analysis is a very useful tool in investigating short- lasting epileptic or non- epileptic phenomena. The authors use this technique in different clinical situations as follows: frequent seizure- like episodes of suspected or proven epileptic etiology, with special reference to absence like and myoclonus- like episodes; motor manifestations, paroxysmal psychic phenomena, and fits induced by visual stimulation. Further indications were as follows: long-lasting pathological stupor states of suspected epileptic origin, long-lasting EEG discharges with unclear clinical correlations, precise analysis of partial epileptic seizures. The results show that, depending on patient selection, video- EEG analysis significantly contributed to precise diagnosis of epileptic seizures as well as to differentiation between epileptic and nonepileptic fits. In a few cases, rare, unsuspected epileptic conditions could only be identified by means of video- EEG analysis. The paper has been completed with a few brief illustrative case reports.]

[Phrenic nerve pacemaker- the first implantation in Hungary]

KLAUBER András, MORVAY Balázs, GERHARD Exner, PASI Talonen

[As a result of a traffic accident on July 15, 1994 a 20 years-old girl immediately became tetraplegic at the C2 level. She had no spontaneous respiration and she needed a respirator. The neurological status has not changed, the total spinal cord lesion has not improved. Her general condition was satisfactory after the treatment of complications (some pneumonia, decubitus, etc.). She underwent an operation on May 31, 1995 and she was given a phrenic pacemaker. The equipment has been working without any problem for fifteen months. Although phrenic nerve pacing is not new for experts, our case is worth presenting since she was the first in Hungary who survived the high cervical spine injury. She lives at home without a respirator, restrained but yet tolerably. ]

Fluoxetine use is associated with improved survival of patients with COVID-19 pneumonia: A retrospective case-control study

NÉMETH Klára Zsófia, SZÛCS Anna , VITRAI József , JUHÁSZ Dóra , NÉMETH Pál János , HOLLÓ András

We aimed to investigate the association between fluoxetine use and the survival of hospitalised coronavirus disease (COVID-19) pneumonia patients. This retrospective case-control study used data extracted from the medical records of adult patients hospitalised with moderate or severe COVID-19 pneumonia at the Uzsoki Teaching Hospital of the Semmelweis University in Budapest, Hungary between 17 March and 22 April 2021. As a part of standard medical treatment, patients received anti-COVID-19 therapies as favipiravir, remdesivir, baricitinib or a combination of these drugs; and 110 of them received 20 mg fluoxetine capsules once daily as an adjuvant medication. Multivariable logistic regression was used to evaluate the association between fluoxetine use and mortality. For excluding a fluoxetine-selection bias potentially influencing our results, we compared baseline prognostic markers in the two groups treated versus not treated with fluoxetine. Out of the 269 participants, 205 (76.2%) survived and 64 (23.8%) died between days 2 and 28 after hospitalisation. Greater age (OR [95% CI] 1.08 [1.05–1.11], p<0.001), radiographic severity based on chest X-ray (OR [95% CI] 2.03 [1.27–3.25], p=0.003) and higher score of shortened National Early Warning Score (sNEWS) (OR [95% CI] 1.20 [1.01-1.43], p=0.04) were associated with higher mortality. Fluoxetine use was associated with an important (70%) decrease of mortality (OR [95% CI] 0.33 [0.16–0.68], p=0.002) compared to the non-fluoxetine group. Age, gender, LDH, CRP, and D-dimer levels, sNEWS, Chest X-ray score did not show statistical difference between the fluoxetine and non-fluoxetine groups supporting the reliability of our finding. Provisional to confirmation in randomised controlled studies, fluoxetine may be a potent treatment increasing the survival for COVID-19 pneumonia.

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

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.

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.

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.
