[Subtype diagnosis, treatment, complications and outcomes of primary aldosteronism and future direction of research: a position statement and consensus of the Working Group on Endocrine Hypertension of the European Society of Hypertension – excerpts]

KOVÁTS Viktória, ALFÖLDI Sándor

[Primary aldosteronism is a frequent cause of secondary hypertension requiring a specific pharmacological treatment with mineralocorticoid receptor antagonist or with unilateral adrenalectomy. These treatments have shown to reduce the excess of cardiovascular risk characteristically associated with this disease. In this consensus, we discussed the procedures for the diagnosis of primary aldosteronism, we address the strategies for the differential diagnosis of primary aldosteronism subtypes and therapy. We also discuss the evaluation of outcomes and provide suggestions for follow-up as well as cardiovascular and metabolic complications specifically associated with primary aldosteronism. ]

[Unattended automated office blood pressure measurement versus classic office automated blood pressure measurement in a hypertension outpatient clinic]

LÉGRÁDY Péter, FEJES Imola, CZOMBOS András, ÁBRAHÁM György

[Accurate measurement of blood pressure is a fundamental prerequisite requirement for an appropriate management of arterial hypertension. In order to eliminate the well-known limitations of classic office blood pressure measurements, the so-called unattended automatic office blood pressure measurement method can be a solution. In 52 patients arriving for regular followup into one of the Hypertension Outpatinet Clinic of the Nephrology-Hypertension Center of the University of Szeged 3-3 blood pressure measurements were made at 1-1 minute intervals first by a doctor with an MIT5 automatic device and then in a separate room unattended, starting alone by the patient with a Hem-907 device. ]

[Effect of beta-blockers with or without vasodilating properties on central blood pressure]

BENCZÚR Béla

[Beta-blockers are more and more excluded as frist-line option in recent hypertension guidelines – they are mainly used in the case of compelling indication. However beta-blockers are not a homogeneous drug-class as several differences exist between them regarding their effect on metabolism or vasoconstriction/vasodilation. The clinical implication of central blood pressure has recently arisen into the focus of interest in the light of the fact that different antihypertensives exert different effect on central blood pressure. The theory of ”stiffness-gradient” may help us to deepen our knowledge regarding the physiology of central blood pressure. Several studies investigated the effects of different beta-blockers on central blood pressure. Based on the unique effect of beta-blockers with vasodilating properties it can be emerged to form this group of drugs as a new antihypertensive class. ]

[Hypertension, cognitive function and dementia – Significance of antihypertensive therapy]

GAJDÁN Nikolett, ÁBRAHÁM György

[The significance of hypertension as one of the major cardiovascular risk factor is unquestionable. By achieving target blood pressure values differentiated by age and comorbidities, the risk of cardiovascular events can be significantly reduced. However, it is essential to the quality of life the patient spends the extra years of life thus gained. This is a really complex issue affecting many co-disciplines, but one of the most important of these is the mental health, maintaining cognitive functions, and avoiding dementia. High blood pressure impairs the blood supply to the target organs, including the brain, by damaging the smooth muscle of the arteries and accelerating atherosclerosis, which increases the risk, the frequency and the severity of mental decline in proportion to the degree of tension. This means serious implications not only for the individual, but for the family and the society, as well. A particular contradiction is that treating blood pressure to the target range does not automatically means preserving cognitive functions and avoiding the risk of dementia. Meta-analyzes of large studies have shown differences between the individual antihypertensive groups have been confirmed in this respect as well. Inhibitors of the renin-angiotensin system and calcium antagonists – mainly dihydropyridines – appear to be a priority in this regard. The authors provide an overview of the relationship between hypertension and mental abilities, with a review of the literature on the effects of antihypertensive therapy, with particular reference to the effects on cognitive function and dementia. ]

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.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[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.]

XU Yifan, HE Yuxin , XU Wu, LU Tianyu, LIANG Weibang, JIN Wei

Background – Up to now, the risk factors related to intracranial infections after transsphenoidal pituitary adenomectomy remain controversial. Purpose – To analyze the risk factors related to intracranial infections after transsphenoidal pituitary adenomectomy under an endoscope, and to provide evidence for preventing and controlling the occurrence and development of infections. A total of 370 patients receiving endoscopic transsphenoidal pituitary adenomectomy in our hospital from January 2014 to October 2017 were selected. The risk factors related to postoperative intracranial infections were analyzed. The hospitalization lengths and expenditures of patients with and without intracranial infections were compared. Of the 370 patients, 18 underwent postoperative intracranial infections, with the infection rate of 4.86%. Intraoperative blood loss >120 mL, cerebrospinal leakage, diabetes, preoperative use of hormones, macroadenoma as well as surgical time >4 h all significantly increased the infection rate (P<0.05). Preoperative use of antibacterial agents prevented intracranial infection. Compared with patients without intracranial infections, the infected ones had significantly prolonged hospitalization length and increased expenditure (P<0.05). Discussion – It is of great clinical significance to analyze the risk factors related to intracranial infection after endoscopic transsphenoidal pituitary adenomectomy, aiming to prevent and to control the onset and progression of infection. Intracranial infections after endoscopic transsphenoidal pituitary adenomectomy were affected by many risk factors, also influencing the prognosis of patients and the economic burden.

Valproic acid associated pleuropericardial effusion: case report

DEMIR Figen Ulku

Introduction - Valproic acid is an effective antiepileptic and mood stabilizer used in the treatment of many neurological and psychiatric disorders. Although there are frequently seen side effects, effusions between layers of pleural and pericardial membranes are rare to be seen. Case - Pleuropericardial effusion was detected in a 23 years old woman who was under valproic acid treatment because of epileptic seizure. After 1 year of valproic acid treatment, patient complained of dyspnea. As all the researches intended on etiology were usual, valproic acid has been thought to be responsible for the matter. Control examination after 1.5 months regarding the end of treatment revealed complete recovery of pleuropericardial effusion. Discussion - Pleural and pericardial effusions are rarely seen complications related to the use of valproic acid. It must also be kept in mind that valproic acid causes a potential for such side effects which can be blamed etiologically when the other possibilities for patients are excluded.
