[The most prevalent of the independent headache disorders (30%) is tension-type headache (other types: migraine 4-10%, cluster 0.04-2.4%). These patients represent 50-90% of the patients in the "Headache Outpatient Clinics". This justifies a review of the latest biochemical data aimed at elucidating the pathomechanism of the disease. According to the criteria of the International Headache Society (IHS), two main forms of tension-type headache are distinguished. Tension-type episodic headache: fewer than 15 attacks per month, but at least 10 attacks lasting from 30 minutes to 7 days. Typically, they are pressing, tight, but not throbbing. Mild to moderate pain, bilateral, around the temples or forehead, pan-like, not increasing with normal physical activity, not accompanied by photophobia or phonophobia. Chronic tension-type headache: more than 15 attacks of headache per month, lasting all day and with features similar to the episodic form, for at least 6 months. In this summary, we first present the main experimental findings and then the conclusions that can be drawn from them. ]

[Reoperation of recurrent supratentorial lobar gliomas (astrocytoma, glioblastoma)]

ÁFRA Dénes, SIPOS László

[Hundred-nine patients with recurrent supratentorial gliomas were reoperated during the last 15 years at the National Institute of Neurosurgery, Budapest. The patients were grouped according to the WHO classification based on the first histology. Fifty patients with low grade (A 2), 30 with anaplastic astrocytoma (A 3) and 29 with glioblastoma multiforme (GM) were reoperated on. Nine patients with low grade astrocytoma were irradiated following the first operation. They survived 5 to 14 months (median value 7 months). Those 22 patients who were irradiated after the reoperation survived longer despite the malignant tranformation of their tumour. The median survival time was 24 months. Twenty-four patients with anaplastic astrocytoma received radiotherapy after the first operation in a total dose from 50 to 60 Gy. Six patients did not give their consent. The median survival after the second operation was 5.5 months. Four patients also received chemotherapy and 1 of them is still alive 4 years after the reoperation. Out of the 29 patients operated on with glioblastoma 20 were irradiated. The median survival after the reoperation was 3 months, and only a few patients lived longer than 6 months. Chemotherapy itself did not influence the survival time significantly in either group. The survival time was influenced significantly by the first histology. Radiotherapy after the reoperation prolonged the survival time significantly, especially in the group of patients with primary low grade astrocytoma. Reoperation of patients with malignant astrocytoma who were irradiated immediately after the first operation extended the survival time slightly.]

[Comparative human immunohistochemical investigations of peptidergic innervation of embryonal and adult cerebral blood vessels]

BÜKI András, DÓCZI Tamás, HORVÁTH Zoltán, FÜRTÖS András

[Peptidergic fibres innervating human embryonic and adult cerebral blood vessels were screened for calcitonine gene-related peptide, neuropeptide-Y and substance-P immunopositive fibres, the mediaadventitia border displayed a network-like fibre arrange ment. There was no significant difference either in the distribution of the individual peptidergic fibres or in the age-dependent appearance of peptidergic networks. On the basis of these results it seems to be unlikely that the different clinical course of juvenile and adult subarachnoid haemorrhages could be the result of an age specific difference of peptidergic fibre distribution influencing the neurogenic mecha nisms of cerebral autoregulation.]

[Statistical evaluation and pathological significance of the incidence of corpus amylaceum]

LEEL-ŐSSY Lóránt

[Objective: Semiquantitative evaluation of the corpus amylaceum (polyglucosan body) was carried out by a method reported before on a 1407 autopsy - partly biopsy - material. Design: The present report contains the data of the occurrence of corpus amylaceum in different disease groups demonstrated in tables expressed in numbers and percentage evaluated by homogenity examination. Setting: The manifold neuropathological examination enabled the reaching of some implications of clinical significance too. Material and method: The material involved a great number of cases not reported before. The cases were classified according to their ages and different diseases as well as a new grading system of quantitative evaluation of the frequency of corpus amylaceum in various localizations. Main outcome measures: The most important aspects were the examination of the predilection sites, the elucidation of the development of corpus amylaceum and occurrence in different conditions and diseases. Results: The method and examination permitted drawing conclusions as follows: 1. The chronic, recurring vascular-barriere disturbances appeared significant in the formation of corpus amylaceum. - 2. There was not an expressive difference between the ischemic and hemorrhagic vascular diseases considering the number of corpus amylaceum nor did more corpus amylaceum occur in Alzheimer's disease than in aged. - 3. Greater amount of corpus amylaceum may be found in some spinal cord lesions. – 4. The formation of corpus amylaceum was not observed in the regions of astrocytic gliosis (e.g. postraumatic) or in astrocytomas. This finding needs further study. - 5. The linear correlation between age and the increased quantity of corpus amylaceum may also be proved statistically. Conclusions: It deserves particular attention that more mechanisms may play a role in the formation of corpus amylaceum such as the insufficiency of astrocytes in the utilization of glucose which may be associated with accumulation of some carbohydrate polymers and glycogen. The increased volume of cerebrospinal fluid in the predilection sites is also an important factor. The spinal cord proved to be a prominent predilection site, where the great amount of corpus amylaceum occurred in some diseases which may be explained by the increased quantity of stress proteins. The final conclusion is that the corpus amylaceum has a pathog nostic significance, but it has a tendency for higher occurrence in some conditions.]

[Progressive myoclonus epilepsy - A review and case histories]

JANSZKY József, HALÁSZ Péter, PERÉNYI József, SISKA Éva, RÁSONYI György

[Progressive myoclonus epilepsy (PME) syndrome is a heterogeneous entity underlain by rare genetic diseases. The most frequent origins of progressive myoclonus epilepsy are: Unverricht-Lundborg disease, Lafora's disease, ceroid lipofuscinosis, MERRF (myoclonus epilepsy with ragged red fibers) and sialidosis. Action myoclonic jerks, epileptic seizures, mental deterioration, neurological impairments are the four main symptoms of PME syndrome. Nowadays in more and more cases a causal diagnosis is possible in the PME syndrome. In this paper clinical data and findings of our 10 outpatients suffering from PME were analysed retrospectively. Electrophysiological, neuroimaging and histological examinations were performed. On the basis of the findings of the 10 patients 6 suffered from Unverricht-Lundborg disease, 1 from Lafora disease and 1 from MERRF In 2 patients we were not able to find specific diagnosis. Among our patients gypsy nationality occurs in a relatively large proportion and we know of more gypsy PME cases under care of other centres. It may raise the question whether Hungarian gypsies suffer from PME more frequently. This paper - to our knowledge – is the first study dealing with a group of PME cases in Hungary.]

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

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

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. ]

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.
