PURPOSE: The aim of the study was to examine the role of Doppler ultrasonography of the portal vein in predicting esophageal variceal bleeding in patients with liver cirrhosis and portal hypertension by comparing the ultrasound data to the endoscopic findings. PATIENTS AND METHODS: 99 patients with liver cirrhosis and esophageal varices underwent color(More)
BACKGROUND The aim of this prospective, randomized trial was to compare analgesia, sedation, and cardiorespiratory function in children after thoracoscopic surgery for pectus excavatum repair, using two types of analgesia--epidural block with bupivacaine plus fentanyl vs patient-controlled analgesia (PCA) with fentanyl. METHODS Twenty-eight patients(More)
In two patients undergoing open heart operations, electrochemical burns developed at the sites of connection to an external pacing system. Investigation revealed that failure of the pacing generator caused a small, continuous, direct current to pass through the patients, resulting in electrolysis at the sites of contact with the pacing and grounding wires.(More)
ZIEL DER STUDIE: Erhöhte Konzentrationen des Urokinase-Typ Plasminogen-Aktivators (uPA) und seines Inhibitors (PAI 1) sind bei einer Reihe von malignen Erkrankungen mit einer schlechten Prognose verbunden. Entsprechend immunhistochemischer Messungen werden uPA und PAI 1 von den meisten Schilddrüsenkarzinomen exprimiert. Es konnte allerdings kein(More)
The performance of the Technicon Chem 1+ chemistry analyzer with the Syva Emit ethyl alcohol assay in plasma and urine was evaluated. Spiked specimens from 0 to 600 mg/dL were tested, and expected versus measured concentrations were monitored. Linear regression line equations of y = 0.9314x + 5.4 and y = 0.9005x + 4.6, and correlation coefficients (r) of(More)
OBJECTIVE The current guidelines for the management of adrenal incidentaloma advise hormonal and radiological follow-up of patients for 2-5 years after the initial diagnosis. However, the vast majority of adrenal incidentaloma are non-functional benign cortical adenomas that require no treatment, so the routine application of the current strategies often(More)
Computed tomography and/or magnetic resonance imaging were performed in 42 female patients with suspected pelvic mass. Surgical and histopathological reports were compared to the imaging findings, yielding mismatch in five (17.8%) patients. One benign cyst and one case of postirradiation fibrosis were characterized as recurrent tumors, one surgically(More)
To define reliable Doppler parameters in mural arteries of affected bowel loops for quantitative assessment of Crohn disease (CD) activity in pediatric population and compare Doppler parameters with Pediatric Crohn Disease Activity Index (PCDAI). Thirty-four pediatric patients (7 with inactive, 27 with active disease of different severity; 13 male and 21(More)
We measured number of bcl-2, apoptotic, neutrophil, and surfactant apoprotein D (SP-D) positive cells in irradiated rat lungs during different time points after the sublethal whole-thorax irradiation of rats. We also investigated the influence of pentoxifylline (PTX) therapy on these markers. Wistar rats were given 15 Gy thoracic irradiation and PTX (35(More)
