[Our report, commissioned by the New Zealand National Advisory Committee on Core Health and Disability Support Services, focuses on the management of hypertension. Our recommendation is that when deciding whether to start medication for hypertension, we should consider primarily the estimated absolute risk of cardiovascular disease and not just the blood pressure value. Treatment should generally be initiated in patients with a systolic blood pressure of 150-170 mm Hg and/or a diastolic blood pressure of 90-100 mm Hg if the risk of major cardiovascular events within 10 years exceeds 20%. Results from clinical trials show that at this level of absolute risk, 150 patients would need to be treated to reduce the number of cardiovascular events by 1 in 1 year. By implementing the proposal, it is possible to reduce the number of people under 60 receiving medication (mainly women) and increase the proportion of older people receiving treatment. Treatment should start with low doses of diuretics or beta-receptor blockers, unless there are contraindications, because these two groups of drugs alone have been shown to reduce the risk of stroke and coronary heart disease in patients with hypertension. ]

[Medical management of inland catastrophes]

FARKAS József

[The author details the medical consequences of disasters and mass casualty situations. The concept of disaster is definied and compared with that of mass accident. It is pointed out that in principle there are no essential differences between them since both disasters and mass accidents require the application of compromise medicine princliples at the site of the catastrophe and during the course of the hospital treatment. The main point of medical support at the site is the triage based on a numeric system of classification. In hospital treatment it is of great importance to adopt uniform (doctrinarian) principles and practice in order to prevent or decrease complications occurring in almost every extreme situation. Further co-operation of our medical organizations and development of common disaster plans may improve the effectiveness of coping with a possible emergency in our country.]

[The value of colposcopical and cytological examination in the screening of cervical intraepithelial neoplasia]

PETE Imre, BŐSZE Péter, TÓTH Vera, LEHOCZKY Győző

[ From 1980 to 1991, 1379 women with abnormal colposcopic and/or cytologic findings were examined at the Department of Gynecological Oncology at the National Institute of Oncology, Budapest. The sensitivity and specificity of these screening tests were studied retrospectively. All women underwent either cervical excision or conisation. Cytological and colposcopical findings were compared with the histological findings. Sensitivity and specificity of cytology were 49% and 77%, retrospectively. The corresponding figures for colposcopy were 88% and 12%, and for cytology and colposcopy together, 96% and 14%. 1. The low sensitivity of cytology suggests that as many as 50% of CIN lesions will be missed if cytology alone is used for screening. This finding probably justifies our screening policy (i. e., colposcopy should be used as a primary tool). 2. We found 194 asymptomatic patients with carcinoma in situ, 40 with microinvasive and 8 with frank invasive carcinoma. This finding emphasizes the importance of cervical cancer screening. 3. To decrease the false positive and negative rates, the introduction of new scientific results into the every day screening practice is urgently needed. 4. Our data suggest the superiority of a colposcopical screening method to a cytological one; however histological examination must be done independently of a screening method if the suspicion of cervical dysplasia arises. ]

[Digoxin 2 days a week; Can what is wrong be safe?]

[The last 20-25 years have seen significant advances in the use of medication. Blood levels of drugs can now be measured using available laboratory methods, and many effects can now be accurately measured in addition to general clinical monitoring. This has created the basis for the everyday use of pharmacokinetics and pharmacodynamics and a separate discipline, clinical pharmacology.]

[Coronary Angioplasty Versus Excisional Atherectomy Trial]

MATOS Lajos

[Atherectomy reduced coronary stenosis 50% or more often (89%) than angioplasty (80%, p<0.001), and the acute increase in vessel diameter was more pronounced (p<0.001). Atherectomy was associated with more early complications (11%) than angioplasty (5%, p<0.001) and hospital costs were also higher ($11 904 vs $10 637, p<0.006). After six months, the restenosis rate was 50% for atherectomy and 57% for angioplasty (p<0.06). However, the probability of infarction or death at six months was higher in the group treated with atherectomy (86%) than after angioplasty (4,6%, p<0,007).]

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

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.]

[Diagnosis and treatment of microvascular coronary heart disease. Specialities of conditions in Hungary]

SZAUDER Ipoly

[Invasive investigations show that in two-thirds of patients the myocardial ischaemia persists without obstructive coronary disease and any other heart conditions (INOCA). The underlying cause may be microvascular dysfunction (CMD) with consecutive microvascular coronary disease (MVD) and microvascular or epicardial vasospastic angina (MVA). The modern practice of clinical cardiology while using the developed non-invasive cardiac imaging permits exact measuring of the coronary flow with its characteristic indices. All of these improve the diagnosing of CMD-induced myocardial ischemia and provide opportunity to determine primary MVD cases. Since the recognition and treatment of MVD is significantly underrep­resented in the Hungarian medical care, the primary stable microvascular angina (MVA) is described in detail below with its modern invasive and non-invasive differential diagnosis and treatment, concerning especially its frequency provoked by high blood pressure and female coronary heart diseases. There are highlighted all recommended diagnostic procedures available under domestic conditions.]
