BACKGROUND Several studies have shown that heart rate variability plays an anti-oscillatory role in the regulation of blood pressure variability in humans. We tested whether systolic blood pressure variability in patients with a fixed ventricular pacemaker rhythm differs from that in patients with sinus rhythm. METHODS AND RESULTS In 18 patients with a(More)
The objective of this study was to compare the baroreflex sensitivity (BRS) assessed by the new, non-invasive, spontaneous sequence method (BRS-sequence) with the Valsalva manoeuvrebased BRS. Fourteen healthy volunteers were studied in the supine position, during 60 degrees head-up tilt (HUT) and during -30 degrees head-down tilt (HDT). Blood pressure and(More)
INTRODUCTION 91.5% of all chronic HCV infections are of 1b-type in Hungary. Japanese researchers found a correlation between the outcome of interferon (IFN) therapy and the structure of the PKR-Binding Region (aa: 2209-2274) of the viral NS5A domain, especially a particular subsection of the PKR-BR, the Interferon Sensitivity Determining Region (ISDR: aa(More)
A retrospective study was performed on 1040 diabetic patients. The survival time of those treated with first generation sulphonylureas (n = 227) was considerably (P < 0.001) shorter after the first attack of angina pectoris (5 +/- 1 years, mean +/- S.E.) or acute myocardial infarction (6 +/- 1 years) than of those (9 +/- 1 years) on glibenclamide treatment(More)
OBJECTIVE To compare the 24-hour sustained efficacy and safety of a new tramadol once-daily formulation (tramadol OAD) using Contramid((R)) controlled-release technology with a marketed twice-daily formulation (tramadol BID). PATIENTS, DESIGN AND SETTING: 431 patients with osteoarthritis of the knee were enrolled in this randomised, double-blind,(More)
Malignant transformation within a dermoid cyst is a rare event. The most common transformation is to squamous cell carcinoma. Patients are often elderly and present with advanced disease. The prognosis tends to be very poor. We present a case of locally invasive squamous cell carcinoma arising from a dermoid cyst in a 48-year-old lady. She underwent(More)
In Hungary, mortality rates from colorectal cancer are dramatically high, therefore the reduction by population screening as a public health measure is considered as one of the priorities of National Public Health Program. In the beginning, a human-specific immunological test was applied in the "model programs", as a screening tool, to detect the occult(More)
Pharmacological stimulation of erythropoiesis was studied in patients selected for open heart surgery, and undergoing a programme of autologous blood predonation prior to surgery. Sixteen patients (group I: ery) received 4000 I. U. of recombinant human erythropoietin (r-huepo) subcutaneously weekly three times during a 3-week period preoperatively, another(More)
Circulatory consequences of cardiac arrhythmias are not always evident. Proper interpretation of the clinical symptoms in certain cases requires assessment of the patients' other hemodynamic characteristics. The authors present the case of a patient with left ventricular hypertrophy, who developed severe circulatory failure at the time of artrioventricular(More)
