[The Comprehensive Aphasia Test in Hungarian]


[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. ]

[Case report about the choice of care at Olajág Elderly Home in Budapest during the COVID-19 epidemic in spring 2020]

PETRÓ Kata, PETKE Zsolt, RADNAI Zoltán, SZIRMAI Viktor

[During the COVID-19 pandemic caused by the SARS-CoV-2 virus, elderly people in long-term nursing homes were espe­cially risks exposed. In this study, the au­thors analyse the causes of local outbreak at the Olajág Elderly Home Vezér street facility in Budapest and the means and ways to curb the spreading of infection. They summarise the measures, which proved to be effective in isolation and treat­ing the patients. The number of infected residents as well as the course of the disease are demonstrated by statistical data. The authors consider as pre-eminently important to identify asymptomatic but in­fec­ted residents, further the rapid introduc­tion of screening tests, strict compliance with protocols, patient path regulation and the use of enhanced, supportive communication.]

[The significance of the identification of SARS-CoV-2 virus and the possible errors of the sampling method]


[The COVID-19 pandemic caused by SARS-CoV-2 virus while emerging suddenly and spreading throughout the globe challenged seriously also the modern medicine. Diag­nostic methods recognising viral infections of the upper airways developed essentially in the last 20 years, and it was specifically progressing during the SARS and MERS epidemics thus facilitating the recognition and identifica­tion of infections by influenza, RS- and adenoviruses as well. Nevertheless the present novel coronavirus (SARS-CoV-2) also de­mon­strated that the relatively simple procedures of naso- and oropharyngeal sampling are fallible too. Thus they may have a relatively high risk of false-negative outcomes. However the correct sampling prior the RT-PCR tests provides reliable diagnosis by high sensitivity and specificity. Thus improving the quality of sampling and avoiding failures by correct training and education of the personnel make more reliable the detection of viral infection or indicate recovery after the infection. Finally, this is a key issue while overcoming the present pan­demic.]

[Minority students in Hungarian medical training]

SZÉL Zsuzsanna

[General health of minority people is usually worse than that of their majority peers and they often expe rience discrimination in the healthcare system. According to international literature, physicians belonging to any minority group are more likely to care for other mi nority people, therefore they may play a key role in reducing healthcare inequities. Anonymous, online questionnaire was distributed to medical students of the four Hungarian universities with medical schools (response rate was 8.86%). In this paper, we analyze our collected data about perceived discrimination with descriptive statistical methods. Results of confirmative statistical analyses (statistical tests) were considered exploratory in nature. 29.6% of respondents self-identified as a member of any minority. 63.0% of minority students and 53.8% of women indicated that they realized discriminated or were harassed in the last 12 months, meanwhile, 37.8% of non-minority students and 31.9% of males have experienced discrimination. Dis­cri­mi­na­tion related to ethnic origin, sexual orientation and disability are regarded as the most widespread forms of discrimination according to our respondents. Students are most likely to say that there is no age related discrimination on the grounds of age – both being under 30 years old (12.0%) and being over 55 (8.6%). Being the member of any minority group seems to have no effect on student’s/ one’s opinion how widespread the forms of dis crimination are. Minority students are more comfortable to work with a member of another minority. However male students feel more uncomfortable to work with a member of sexual or gender minorities compared to female counterparts. Mi­no­rity students tend to be more critical to the universities’ efforts to enhance diversity. Minority students and females may play a key role in reducing discrimination in medical training and in the healthcare system and in providing high-quality care for individuals who belong to any minority. Although there are more females than males in medical training they still report higher occurrence of perceived discrimination. However, it is important to emphasize the low response rate in our study, which does not allow us to draw any general conclusions.]

[Not all young, athletic university students have optimal blood pressure. Results of the May 2019 Measurement Month (MMM19)]

PATÓ Anna, NÉMETH Zoltán, JÁRAI Zoltán, KOLLER Ákos

[For about 100 years, it has been known that persistently high blood pressure (hypertension) is the leading cause of cardiovascular disease deaths, such as major risk factors for heart failure, myocardial infarction, stroke, kidney and eye disease. Unfortunately, one of the characteristics of hypertension is that it remains undetected for a long time until damage to one or more organs has already occurred. Therefore, it is very important that systemic blood pressure is monitored from time to time, especially above 45 years of age. The prevalence of hypertension is more than 35% in the Hungarian population. Recent data have pointed out that hypertension may occur at a younger age, although at a lower frequency. Our studies were conducted in the context of the May 2019 Measurement Month (MMM19), an international campaign that draws attention to hypertension and the lack of systematic screening at population level. We hypothesized that hypertension may occur in young, apparently healthy university students. The studies were conducted among students of the University of Physical Education (n = 33; 25 males, 8 females). The mean age was 24.3 years (20–34 years). To measure blood pressure, an automatic blood pressure monitor (Omron MIT5) was used, placed on individuals’ upper arms, as specified in the guidelines, in a relaxed, sitting position. The measurements were repeated three times at one-minute intervals and the average of the three measurements was statistically analyzed. Blood pressure values (mean ± SEM, averaged over 3 measurements) in the student population were systolic 121.9 ± 14.4 mmHg, diastolic 75.1 ± 9.1 mmHg, mean 90.7 ± 10.9 mmHg, and heart rate: 46.8 ± 5.3 mmHg. Although mean blood pressure was within the normal range, higher values were also found in some individuals. Systolic blood pressure fell by 33% due to elevated normal blood pressure, respectively of Grade 1 hypertension. These data confirmed our hypothesis that hypertension may occur at a young age, despite the fact that members of the study population exercise regularly, which is an important preventive factor in the development of cardiovascular disease. These results underscore the importance of regular blood pressure measurement in adolescents, which may reduce the global spread of hypertension and prevent the development of a number of cardiovascular diseases, including stroke, heart attack, renal failure and mental decline.]

[Systolic and diastolic blood pressure by height, BMI, gender and age between 14 and 18 years of age]


[The aim of the screening program was to investigate blood pressure levels in different ages according to obesity. Blood pressure, heart rate, body composition, bodyweight, height and BMI were assessed. 2202 adolescent (1326 girls, 876 boys) participated in the screening program. The mean systolic blood pressure of all screened adolescents was 126.34 ± 12.55 mmHg. Boy/girl values were 131.87 ± 13.59/117.49 ± 5.69 mmHg, p < 0.001. The mean diastolic blood pressure of all screened adolescents was 71.86 ± 8.74 mmHg. Boy/girl values were 72.61 ± 9.17/66.69 ± 5.04 mmHg, p < 0.001. The 50%, 90%, 95%, and 99% thresholds and cases for systolic, diastolic blood pressure, and the BMI and BodyFluid thresholds, detailed for 14–18 year olds, girls and boys, are tabulated. Systolic blood pressure (SBP) was over 99% in 12 girls (14- year-olds), 39 (15), 42 (16), 33 (17), 5 (18) to height. SBP was over 99% in 17 boys (14-year-olds), 73 (15), 100 (16), 33 (17), 5 (18) to height. It is emphasized that systolic blood pressure (SBP) is > 99% in 12 girls (14 years), 39 (15), 42 (16), 33 (17), 5 (18) to body height. SBP > 99% for 17 boys (14 years), 73 (15), 100 (16), 33 (17), 5 (18) to body height. Elevated diastolic values were associated with elevated systolic values, but less occurred. The percentage of high blood pressure was more frequent among boys and girls who were in the overweight group (58.6% and 18.6%). Normal blood pressure is higher in overweight and obese adolescents and is a significant risk factor for developing high blood pressure in young adulthood.]

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

[Interrelations between antidepressants and diabetes]

HARGITTAY Csenge, GONDA Xénia, MÁRKUS Bernadett, VÖRÖS Krisztián, TABÁK Gy. Ádám, KALABAY László, RIHMER Zoltán, TORZSA Péter

[Diabetes and depression are frequent comorbidities. They are a heavy burden by themselves, however, as comorbidities increase additionally the number of diabetes-related complications, morbidity, and mortality. In the background of interrelations, there are both well-known and hypothetical mechanisms. The aim of the present review is to outline these interrelations between antidepressants and diabetes and to discuss the effect of medications on carbohydrate metabolism respectively. Anti­depressant treatment on the one hand may improve mood, cognitive function and medication adherence leading to an improved glucose metabolism, on the other hand through their metabolic side effects, they may worsen carbohydrate metabolism. Concerning metabolic side effects, selec­tive serotonin reuptake inhibitors are the sa­fest, while tricyclic antidepressants and mo­noamine oxidase inhibitors should be administered under close monitoring. Se­rotonin and noradrenaline reuptake inhibitors may deteriorate gly­cae­mic control via increased noradre­nergic activation. Novel antidepressants, how­ever, have a neutral or positive impact on gly­caemic measures. Screening for and temporally adjusted treatment of depres­sion may decrease the risk of comorbidities ge­nerated complications. While caring for diabetic patients with depression, one should consider metabolic side effects of antidepressants and close monitoring of carbohydrate metabolism.]

[Event-related potentials and clinical symptoms in schizophrenia]


[The investigation of schizophrenia’s aetiology and pathomechanism is of high importance in neurosciences. In the recent decades, analyzing event-related potentials have proven to be useful to reveal the neuropsychological dysfunctions in schizophrenia. Even the very early stages of auditory stimulus processing are impaired in this disorder; this might contribute to the experience of auditory hallucinations. The present review summarizes the recent literature on the relationship between auditory hallucinations and event-related potentials. Due to the dysfunction of early auditory sensory processing, patients with schizophrenia are not able to locate the source of stimuli and to allocate their attention appropriately. These deficits might lead to auditory hallucinations and problems with daily functioning. Studies involving high risk groups may provide tools for screening and early interventions; thus improving the prognosis of schizophrenia. ]
