Management of cavernous angiomas of eloquent brain areas by means of image (MRI or CT) - guided key-hole craniotomy

KÖVÉR Ferenc, DÓCZI Tamás, VON JAKO C., BALÁS István

Details of neurosurgical management of four patients suffering from intractable epilepsy caused by cavernous angiomas of subcortical eloquent brain areas are presented. Two of four cavernomas were not visualized by CT or angiography but only by MRI. MRI or CT stereotactic image-guided key-hole craniotomy and resection of the lesion from the dominant anterior central gyrus (2 cases), from the dominant superior temporal gyrus or from the dominant supramarginal gyrus were performed without any morbidity. The postoperative hospital stay was 3-5 days and all four patients experienced improved seizure control. We conclude that stereotactic image-guided key-hole craniotomy and microsurgical resection offer significant advantages in the treatment of cavernous malformations. Surgical indications include medically refractory epilepsy, intracerebral haemorrhage and/or progressive neurological deficit.

[Examination after the first epileptic seizure]

RÓZSAVÖLGYI Margit

[106 patients were examined after the first epileptic seizure; they were divided into two groups based on the clinical data. The two groups were: the group of provoked seizure and the group of non-provoked (isolated) seizure. 95 patients were in these two groups. The others showed focal epileptiform EEG alterations or generalized epileptiform activity without seizures and, because of the very low number of patients, the author excluded them from the study. A questionnaire was used to study and to search for the history of the disease and provocative factors. The familial occurrence of epilepsy was quite often among the patients, similar to primary generali zed epilepsy (17.9%). There were no important previous illnesses, except the provoked seizure. The provocative factors played a significant role in the occurrence of the first seizure. The different provocative factors appeared in greater numbers in the different groups. The anxiety occurred as a possible provocative factor in the group of non provoked seizure. The EEG after the first epileptic seizure showed epileptiform activity in the lower percentage than was predictable from the literature. The mobile long term EEG was shown to be an effective method of examination for epileptiform activity.]

[Interpretation of the resoults of DNA image analysis in astrocytomas - biology and prognosis]

SZŰCS István, LEEL-ŐSSY Lóránt, KINDLER Miklós

[Ploidy and proliferative activity of 72 astrocytomas (except glioblastomas) were examined with nuclear DNA content by computed image analysis. The majority of samples originated from paraffin embedded material but they were partly obtained from surgical biopsy by printing or smear technique. The 72 astrocytomas were classified according to Kernohan's grading system. Different areas of tumours were evaluated according to their ploidy (euploid, diploid, aneuploid and heterogenous ranges), proliferative parameters and DNA indices. The transitional zone sometimes revealed higher proliferative index with euploidy. The DNA distribution showed greater population even in the case of moderate malignancy. Uniform – single population - DNA distribution characterized the benign type in 79% with DNA index within the diploid range. The remaining 21% had aneuploidy with another population (heterogenous). The higher the malignancy the greater the population may be found with the higher percentage of S phase cells. The mitotic forms displayed higher DNA index as well as G 2 phase even in the transitional zone of the tumour. The heterogeneity with higher percentage of S- phase correlated well with the histological type of the tumour. The follow-up study of some astrocytomas sometimes did not show a good correlation with the DNA values. However a good correlation was found between the number of cells with higher S and G 2 phases and the type of histogram in the majority of cases studied. The different parts of the tumours also varied in these respects, which should be taken into consideration during needle biopsies.]

[Suggestion for new classification of ischemic stroke]

KOPA János, RÁDAI Ferenc, SZÁSZ Krisztina, REPA Imre, HUSZÁR Péter, BESZTERCZÁN Péter, GYŐRBÍRÓ Zsolt

[The classifications of ischemic damage of the brain which have been in use cannot give a suitable orientation about the pathoanatomical background of this disease. As a result of this, the authors investigated the data of 1000 cerebrovascular indoor stroke patients who had been investigated by CT or MRI. The clinical and radiological data were compared. Their conclusion was: more than 80% of the cerebrovascular diseases are ischemic lesions. All of the ischemic patients have some vascular disturbances. In the cases of all patients having some ischemic event (transient ischemic attack, reversible ischemic neurological deficit, prolonged reversible ischemic neurological deficit, completed stroke) there are enduring ischemic lesions which can be demonstrated by CT or MRI. Comparing the neurological signs and the CT or MRI findings of the patients we could establish two groups of ischemic lesions: solitaire and multiplex infarcts. They can be divided into 3 subgroups. Among the solitaire infarcts is subgroup S-1: the patient has no neurological sign and in the CT or MR pictures there is only one lesion under 10 mm in diameter. S-2: mild neurological signs with one infarcted lesion about 15 mm in diameter; as a partial lesion in the territory of a cerebral vessel; S-3: severe neurological signs with total or almost total damage in the territory of a cerebral vessel. Among the multiple infarcted patients there is subgroup M-1: the patient has no neurological sign, but in the CT or MR pictures there are many small (under 5 mm in diameter) infarcted zones; M-2: the patient has mild neurological signs and multiple infarcted zones (5-15 mm in diameter) can be seen in the CT, MRI picture; M-3: the patient has very severe neurological signs and/or dementia. The infarcted areas consist of small and one or more sites of partial or total damage in the territory of a cerebral vessel. This classification is better in showing the state of the patients and the pathoanatomical distur bances. The authors have used this classification in clinical practice without any problems for a year.]

Analysis of IQ and genotype in duchenne and becker muscular dystrophy

LÁSZLÓ Aranka, PÓR Erzsébet, CSEPREGI Zsuzsa, ENDERFFY Emőke, RASKÓ István

The authors analysed the association of genotype and the intelligence quotient (IQ) examined with age dependent psychological methods (Wechsler, Vineland, Binet, Raven IQ tests) in 41 Duchenne (DMD), 2 intermediate MD, and 14 Becker type muscular dystrophic (BMD) patients (mean age2.5-37 y). ln 61.4% of the DMD/BMD exon deletion of dystrophin gene was found, while in 38.6% no deletion was detected. The assessment of the genotype was made by using multiple PCR method, examining the most frequent deletion of 18 exons and the muscle specific promoter. Among the deletion patients the distribution of mentol retardation was 28.5%, among patients with non deletion 22.7%. ln 21.4% of BMD patients and in 29.2% DMD patients mentol retardation was detected, the differences were not significant. Similar to the findings of other authors in 4 patients having exon deletions near the 5' end of the gene no mentol retardation was found, but in 14 of 30 patients having deletions near the 5' end of the gene there was. One patient with the largest deletion (exons 12-44) proved to be debil.

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.

[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. 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. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[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. ]

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]
