Late cardiotoxicity after anthracycline chemotherapy for childhood cancer is well recognized sequelae. Many long-term survivors may have subclinical cardiac dysfunction undetectable at a baseline evaluation. Various tests have been utilized for the diagnosis of left ventricular impairment. Recently, low-dose dobutamine stress echocardiography has been(More)
BACKGROUND Primary hosts of Helicobacter heilmannii are domestic animals--cats, dogs and pigs, but rarely is it detected in gastric biopsies from humans. We found H. heilmannii in gastric biopsies obtained from patients living in a predominantly rural area. METHODS We evaluated geographic and demographic data from the area and calculated both the total(More)
AIM To verify an impact of a lymph node revealing solution (LRS) on the number of lymph nodes (LN) revealed in colorectal resection specimens. MATERIAL AND METHOD Fifty-nine cases of rectosigmoid carcinomas divided into two subgroups-stage pT2&3 (20 cases) and ypT2&3 (with pre-operative radiotherapy-39 cases)-were formalin fixed for 42-72 h, serially(More)
The authors present their initial experience with a new echocardiographic method, transoesophageal echocardiography (TEE). From an oesophageal approach it gives a remarkable view of the anatomy and functional parameters of the heart in practically all examined patients. It opens also new diagnostic possibilities. The main advantages of the method include(More)
INTRODUCTION The authors used echocardiography at rest and dynamic stress echocardiography to assess left ventricular function in asymptomatic patients treated during childhood or adolescence by chemotherapy containing anthracyclines. MATERIAL AND METHODS 137 patients were examined (81 men, 56 women) aged 16.6 +/- 4.8 years (median 17 years) where at the(More)
—We present a case study evaluating the potential for identifying placental blood vessels using MRI in large-scale virtual reality environments in order to improve the planning of twin-to-twin transfusion syndrome intervention surgery. Twin-to-twin transfusion syndrome is a condition where the blood vessels of twin fetuses are connected on the shared(More)
