Clinical Neuroscience - 1985;38(04)

[After occlusion of the internal carotid artery, focal ischemic symptoms persist in a quarter of patients. This may be due to an ulcerated surface of the stump of the internal carotid artery or to clots filling the inlet of the occluded artery, and emboli from this may enter the intracranial vessels via the internal carotid artery anastomoses. Further evidence for this hypothesis is provided by presenting the material of 10 patients in whom endarterectomy was justified in preparation for extra-intracranial anastomosis surgery to narrow the external carotid artery inlet. In this way, the carotid fork can be studied. The findings emphasize the pathogenetic role of the carotid stump and suggest its excision when endarterectomy of the external carotid artery is warranted anyway. However, it is also considered to be an option when the ulcerated entrance of the carotid stump is at risk of further embolization. Surgical management is described. ]

[On model theories of endogenous psychoses]

SIMKÓ Alfréd

[The author presents variations in the interpretation of so-called "endogenous" psychoses, from the vague notion of "heredodegeneration" to the nosological and axial-syndromic principle and methodologies based on the progression picture, pointing to the increasing importance of the dominant role of biological, psychopathological and social perspectives. In the models, the author sees relatively valid hypothesis constructs intended to bring together the larger body of knowledge on a topic. Their disadvantage is that their categorical validity is determined solely by their own systematising principle: therefore, models that are too closed are in danger of becoming rigid and dogmatic. Without claiming to be exhaustive, the author only sketches out the brain topological, constitutive and character typological, descriptive-phenomenological, form-phenomenological, psychoanalytic, existential-anthropological, genetic, cybernetic, and broader biological and sociogenetic models of endogenous psychoses. It highlights the importance of their flexibility, resolvability and synthesizability, without which their clinical usefulness, especially in the context of endogenous psychoses, becomes questionable. ]

[Indications for transoral neurosurgery]


[The microscopic surgical technique has made it possible to operate relatively safely on pathological lesions located in the ventral part of the craniocervical transition, often causing severe bulbar symptoms. The indications for this operation are discussed based on the experience of 11 patients operated on with transoral surgery. ]

[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.

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.]

Lege Artis Medicinae

[A short chronicle of three decades ]


[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.]

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Correlations Between Burnout and Socio-demographic and Workplace Related Factors Among Health-care Workers During The Covid-19 Pandemics]


[The present study aimed to assess the level of burn-out among health-care workers in 2020 and its correlations with socio-demographic and workplace related factors. The cross-sectional study was conducted by the means of a self-constructed online survey in the beginning of 2021. The responses of 1965 people were analysed with the help of SPSS 23.0. Descriptive statistics, chi-square and Kruskal-Wallis probes were run (p<0.05). Severe burnout was present in 46.7% of the responders. Age, marital status, type of health-care provided and years spent in the health-care system didn’t show any correlation with burnout. Unsure vision, opinion about salary raise and uncertainty at the workplace influenced the level of burnout significantly (p<0.000). The mental health of health-care workers is in continuous decline, in which the COVID-19 pandemic might play a big role. People with worse mental health feel more uncertain regarding their future and job; this might make providing health-care more and more difficult.]

[Operational Efficiency Investigation from APN Perioperative Perspective]


[In the healthcare system operating theatres have to put great emphasis on quality work, patient safety and efficiency as well, and to achieve this, optimal utilization of theatres is extremely important. The results of researches in this topic in Hungarian and international literature draw attention to a lot of aspects. The study of perioperative periods, and the evaluation of the analysed processes show that theatres could be operated more effectively. As a result of this, more operations could be carried out and waiting time would also reduce. In order to increase the efficiency of the processes, APNs can play a prominent role at several points. According to the experience, the number of people using health care and the number of people waiting for surgery is increasing, which is further increased by the development of the ongoing SARS-CoV-2 (COVID-19) epidemic. Thereby, patients are not satisfied with the service. The work of APNs would also help increasing the contentment of patients during the operation procedures. Taking advantage of the multifunctional role of the nurse due to her knowledge and training, she actively participates in the operation, in the smooth running of the scheduled daily surgical program and contributes to the reduction of the number of missed, planned surgeries.]
