Clinical Neuroscience
[High stroke morbidity and mortality in Hungary have focused to attention on stroke prevention and the organization of adequate therapy. Up till 1990 both cardiovascular and the cerebrovascular mortality had increased. The Precise analysis risk factors' determines the primary and secondary stroke prevention. The most important issues in of prevention are: proper care of hypertension, gradual change of dietary habits of the Hungarian population, and reduction of smoking. The revised stroke classification, published in 1990 suggested the further breakdown of ischemic strokes into embolic, atherothrombotic and lacunar forms. The new categories reflect the pathomechanism, and thus help in planning more successful treatment. The early treatment of embolic stroke with thrombolysis looks promising, thrombolysis in lacunar stroke implies a certain amount of risk. Hemodilution and dehydration therapy in the treatment of different forms of ischemic strokes need to be evaluated differently. Both invasive and non-invasive diagnostic examinations follow a well thought out algorithmic pattern. Since thrombolysis is a possible therapeutic choice, laboratory tests, especially the analysis of hemostatic factors have gained more significance.]

[The role of excitatory amino acids in the pathomechanism of several neuropsychiatric disorders became known in the last few years. Special attention is paid to glutamate, since this has proved to be an excitotoxin under certain pathological conditions. It acts through the ion-channel of the NMDA receptors via enormous Ca++ ion flow into the cell. NMDA antagonists may be of importance in the treatment of Parkinson's disease, which is characterized by increased glutamate hyperactivity. The clinical use of adamantane derivatives might be suggested because of their possible symptomatic and neuroprotective effect.]
Clinical Neuroscience
[Five rare case histories of intracranial occlusive cerebrovascular disease with arteriovenous malformation are presented. In 2 cases the middle cerebral artery and in a further 2 cases the internal carotid artery were occluded (3 ipsilateral frontal and 1 parietal angiomas). In the fifth case a temporal angioma and ipsilateral posterior cerebral artery occlusion was detected. In the first 4 cases extra-intracranial arterial bypass was performed before the excision of the malformation. ]
Clinical Neuroscience
[The majority of Duchenne/Becker muscular dystrophy (DMD/BMD) cases are caused by deletions affecting exons of the dystrophin gene, which results in defective protein synthesis. In order to detect deletions the multiplex PCR method was utilized on the DNA of 15 DMD/BMD patients by amplifying 9 deletion-prone exons as a first step followed by a further 5 exons when necessary. Delection were found in more than 50% of patients by this method which correlates well with that expected from the literature data. This rapid and reliable method is an important diagnostic tool in the precise characterization of muscular dystrophies.]
Clinical Neuroscience
[Fibrinogen and other laboratory variables of 348 patients with various types of stroke were statistically analysed in the acute, subacute and chronic stage of the disease. Seventy two patients with non-vascular disease served as control. The actual level of plasma fibrinogen in cerebrovascular patients was attributed to the following factors: 1. presence of atherosclerotic plaques in extra and intracranial arteries, 2. the time lag between the onset of stroke and laboratory testing, 3. degre of post stroke mobility of the patients. Initial level of fibrinogen is a predictive value of death both in hemorrhagic and ischemic patients. The highest plasma concentration of fibrinogen was found in the atherothrombotic stroke group, in which was a significant negative correlation between the plasma fibrinogen and high density lipoprotein level. It was concluded that fibrinogen is a risk factor in cerebrovascular diseases.]

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.
Clinical Neuroscience
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.

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.
Clinical Neuroscience
[The well-known gap between stroke mortality of Eastern and Western European countries may reflect the effect of socioeconomic differences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomically deprived neighborhoods. ]
