OBJECTIVE To examine the usefulness of determining extended serum cytokine profiles in patients with juvenile rheumatoid arthritis (JRA), for the purpose of improving differential diagnosis and monitoring disease activity. METHODS In a 2-year prospective study, serum levels of interleukin-1 beta (IL-1 beta), soluble IL-2 receptor (sIL-2R), IL-6, IL-8,(More)
Aspergillosis is not a rare disease of the paranasal sinuses; more than 80 cases were reported from 1976 to 1982 in the University ENT Clinic at Graz, Austria. Of 59 patients studied, 27 presented almost metal-dense x-ray shadows resembling foreign bodies in one of the sinuses. By means of light and electron microscopic investigations as well as x-ray(More)
PURPOSE The aim of the study was to investigate the heart rate turn point (HRTP) in the time course of the heart rate performance curve (HRPC) in patients after myocardial infarction, and the relationship between the HRTP, the left ventricular function, and the second lactate turn point (LTP2). METHODS We studied the degree and the direction of the HRPC(More)
815 recent clinical isolates of different species representing pathogenic or saprophytic constituents of human microbial flora were submitted to agar dilution tests. In concentrations above 64 micrograms/ml tyrothricin is in general equally as gramicidin or slightly more effective whereas below 8 micrograms/ml gramicidin is mostly more effective than(More)
The purpose of this investigation was to study myocardial function at rest, during three phases of energy supply, and during recovery. Radionuclide angiography was performed during the aerobic phase (phase I, rest-first lactate increase), the aerobic-anaerobic transition phase (phase II, first lactate increase-second lactate increase), the anaerobic phase(More)
Hematopoietic progenitor cell levels were monitored in the peripheral blood of ten healthy adults receiving a single dose of recombinant human granulocyte colony-stimulating factor (rhG-CSF). The objective was to determine the time and number of progenitor cells released into the peripheral blood, induced by a single dose of 15 micrograms/kg rhG-CSF(More)
The authors evaluated suppressed in vitro functions of peripheral blood lymphocytes (PBL) as a possible tool in the early diagnosis of human lymphoma. In 13 of 22 patients with recent onset of various types of nonleukemic lymphomas (Mb. Hodgkin and non-Hodgkin's lymphomas of B-cell and T-cell origin) the mitogen response of PBL against phytohemagglutinin(More)
In about 10% of patients who are operated on for chronic sinusitis, an aspergilloma is found in the affected paranasal sinus. In order to detect possible underlying immune defects, 25 patients with aspergillomas were subjected to an immunological screening program. The data obtained were compared with those of patients with non-mycotic chronic sinusitis and(More)
A retrospective radiographic study was performed on 142 proven cases of Aspergillosis in the paranasal sinuses. In all but two cases the mycosis was unilateral and in all cases the maxillary sinus was infected. A common radiographic presentation was a homogeneous opacity of the infected maxillary sinus, while about 50% of the cases showed nonspecific(More)
The paper presents a feature-based approach regarding on-line signature recognition, by employing the TESPAR DZ matrices extracted from every signature. These matrices describe the different signature features shapes, such as x, y coordinates, x, y velocity, pressure etc. For better results, the fusion of different features was studied. Three signature(More)
