[Evaluation of gliomas by means of multi-model techniques]

BORBÉLY Katalin

[Gliomas constitute more than 50% of brain tumours. Primary malignant forms recur within 1/2 to 1 year after surgery, and even totally removed benign forms may recur. 50% of recurrent astrocytomas are more malignant than the original tumour. The time elapsing until recurrence strongly depends on the degree of malignity and the surgical removal. However, the age of the patient also plays an important role. Survival of the patient after the establishment of diagnosis also depends on the therapy. Effective treatment requires a knowledge of the degree of malignity as well as differentiation between recurrent tumour and radiation necrosis. CT and MRI scans offer high sensitivity, but poor specificity. Evaluation of tumour metabolism by means of 18F-fluoro-deoxy-glucose positron emission tomography (PET-FDG) helps to determine the degree of malignity of the gliomas, and recurrent tumour can safely be differentiated from necrosis following radiation therapy.]

[Symptomps, localization of cerebral lesions and aetiology of "letter-by-letter" reading]

SÉRA László, MÁRKUS Atilla, BERNÁTH László

[The symptoms, localization of cerebral lesions and aetiology were analysed literally data of 78 patients suffering from pure alexia (letter-by-letter reading). During the 100 years since Déjerine's first case study on the issue was been published our knowledge on the clinical and pathomorphological characteristics of pure alexia has become more exact. On the one hand, clinical symptomatology has narrowed, eg. right homonymous hemianopsia is no regarded as a compulsory concomintant symptom on the other hand, the locus of damage underlying the symptoms may be at various areas of the brain (eg. subangular), not only at the occipital regions. The role of the posterior trajectory system in the reading process emphasized. In addition however, taking into account recent neuropsychological findings, the importance of other areas of the brain is presumable. In accordance with cognitive psychological research of the reading process it is concluded that it is essential the is for our understanding of the whole reading process that all of these factors are taken into consideration.]

[Transoral and posterior fixation for inveterated fracture of odontoid process - Case report]

VERES Róbert, LAKATOS István, KENÉZ József, PENTELÉNYI Tamás

[Combined operative treatment is reported of a fixed malpositioned type III. (according to Anderson-D'Alonso) oblique anterior odontoid process fracture. Due to the ventral and dorsal compression of the spinal canal a part of the dens and a part of the C.li body were transorally removed, and a part of the arch of the atlas also removed by a dorsal approach. The position was fixed by means of a combined method of a transoral Harms-plate and a posterior C.I.-C.II. fransarticular screwing according to Magerl. With this method were achiered proper decompression and stabile C.1.-C.II. arthrodesis.]

[Cerebral aspergillosis]

ILLÉS Zsolt, GARZULY Ferenc, BRITTIG Ferenc, PERENYEI Miklós

[Four cases of cerebral aspergillosis are reported. Brain abscesses developed in a patient with chronic alcoholism and pyogenic urogenital process, and in a baby, treated for aplastic anaemia. Haemorrhagic necroses were found in the other two cases, one of them suffered from agressive hepatitis, the other had lymphoid leukaemia. Pulmonary alterations were observed as part of generalised aspergillosis in all the cases. Early diagnosis of pulmonary processes should be emphasized as the disease can hardly be influenced when neurologic symptoms appear.]

[The effect of the cue-controlled modification of the level of vigilance on the intentional inhibition of seizure in patients with partial epilepsy]

SZUPERA Zoltán, RUDISCH Tibor, BONCZ István

[The cue-controlled modification of the level of vigilance, as one of the methods of self-control appeared to be a practicable therapeutic intervention for the intentional inhibition of epileptic seizures in some special cases of epilepsy. The authors worked out a variation of the above self-control technique, in which the aura imagined in hypnosis was associated with the change in vigilance in patients suffering from partial epilepsy, in order to enable them to try to inhibit the epileptic fits with this associated modification of the level of alertness during auras. The authors report two cases of intractable partial epileptic patients, in which the patients attained the application of this self-control method. The first patient carried out intentional seizure inhibition in 73 cases over one year, reducing the frequency of the fits from the previous 115 to 77. In the second case, the patient was able to decrease considerably even the number of epileptic auras by learning and applying the technique, consequently the number of auras decreased to 7 compared with the 38 fits observed in the previous 8 months, further he was able to terminate the attack in 6 cases out of auras. The authors think, that their method might be useful for a certain group of patients suffering from partial epilepsy to inhibit epileptic attacks, and would mean a new possibility in the management of intractable cases.]

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.
