[The ACE2-Ang(1-7)-Mas axis counterbalances the ACE/Ang II-AT1R axis in our body in order to maintain normal homeostasis. During the Covid-19 pandemic, this protective system came to the fore again and its beneficial effects on the cardiovascular-metabolic system, including the significant antihypertensive effect, are being clarified. In our brief summary, we analyze the essential aspects of this research.]

[Hypertension and Covid-19 - part II.]

SZÉKÁCS Béla, KÉKES Ede, NAGY Judit, KOVÁCS Tibor

[The authors review those components and mechanisms in the two major regulatory systems of circulation and inflammation-coagulation whose internal balance and interactions are pathologically altered during SARS-CoV-2 infection, thereby enhancing lung and systemic inflammation threatening to enter into severe clinical condition. They examine the question of how – in addition to potentially promoting the coronavirus cellular entry and penetration – the RAS inhibitor therapy affects these changes and whether can be supposed difference between the anti-/pro-inflammatory influence of ACEi and ARB treatment of old hypertensive patients representing a remarkably high proportion of victims in COVID-19 epidemic. The paper is focussing to the pathomechanical background of inflammation beyond the direct immunological response to the infection: to the significance of immunological alterations characterizing old hypertensive patients also in basic condition, and to the key components as angiotensin II, ACE2, angiotensin1-7, bradykinin, ARB and ACEi. In conclusion a consideration on optimal point of action is offered in RASi treated and SARS-CoV-2 infected (old) hypertensive patients.]

[The role of stress management in the care of hypertension and the treatment of cardiovascular disease]

SOMOGYI Éva, KISS Zoltán, STAUDER Adrienne

[The aim of this paper is to give an overview of the relationship between stress and hypertension and cardiovascular diseases, furthermore to introduce an evidence based stress management intervention available in Hungary. The correlation between cardiovascular disease and psychosocial factors (including concomitant mental disorders as well as personality traits or the effect of social environment) has been established in numerous studies aimed at investigating pathogenesis or various clinical endpoints. The 2016 Guidelines of the European Society of Cardiology include the assessment and the management of psychosocial problems with behavioral medicine interventions as a I.A level recommendation. The implementation of these guidelines in everyday clinical practice is crucial to decrease cardiovascular risk. This involves the training of health care professionals, the facilitation of multidisciplinary collaboration and the integration of behavioral intervention into everyday care. The Williams Life Skills (WLS) program is an evidence based behavioral medicine intervention aiming to improve stress management and communication skills which implemented internationally and also available all over Hungary. It involves the learning of simple coping strategies that facilitate the successful management of every day psychosocial stress situations and the self-conscious reduction of bodily and psychological tensions. In cardiovascular disease, this improves quality of life and survival. The WLS program is especially recommended for healthcare workers to decrease the negative health consequences of their high stress load and to prevent burnout. Stress may affect both doctors and patients during their interactions. Bálint groups have a positive impact on the physician-patient collaboration and help to reduce burnout by improving the understanding of the diseases from a more complex approach.]

[Wearing a face mask: effect on a doctor – patient relationship. Complicating factors and their compensations]

VONYIK Gabriella, FARKAS Martin, TURNER Andrea, FINTA Ervin, BORSZÉKI Judit

[Wearing face masks plays an important role to effectively decrease the chance of transmitting respiratory diseases. Face masks commonly worn during the Covid-19 pandemic to shield the mouth and the nose, cover about 60- 70% of the area of the face that is crucial for the effective verbal and nonverbal communication and perception of mental states. Face masks may complicate social interaction especially in the medical setting where communication skills and doctor-patient relationship are essential to primary care consultations. Literature was reviewed on the impact of such face masks on effective doctor and patient communication as well as useful alternative ways are suggested to compensate them in order to maintain the effective doctor-patient interaction.]

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

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

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.

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[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.]

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.
