Strangulation ileus caused by malposition of the ureter.

Ileus is one of the most severe diagnoses of the group of acute abdomen events. Some patients with certain forms of bowel obstruction respond well to conservative therapy. However, the diagnosis of strangulation ileus can be delayed in some situations, resulting in high morbidity and mortality in such cases.

Different cardiac loading conditions and haemodynamic monitoring in animal models.

Objective: To develop models of various cardiac loading conditions in an experimental study.

Materials And Methods: A total of 78 piglets, average weight 24 kg were divided into 4 groups under different cardiac loading conditions: Group A were spontaneously breathing pigs without haemodynamic changes, Group B were ventilated animals with increased left ventricular afterload, Group C ventilated with increased right ventricular preload and Group D ventilated with increased afterload of both heart ventricles. Haemodynamic parameters were invasively measured at 60 and 120 minutes.

[Mucinous adenocarcinoma of the appendix--case report].

The authors are describing a case of a patient with the diagnosis of the appendicular cancer. The 66-year-old patient underwent appendectomy because of signs of acute appendicitis, and than in the next step right-sided hemicolectomy because of histological finding of the mucinous adenocarcinoma of the appendix. Mucinous adenocarcinoma is the most common type of appendicular cancer, none the less this diagnosis is very rare.

Comparison of Doppler flow Tei-indexes with pulmonary artery thermodilution measurement of cardiac output in an experimental porcine model.

The objective of our study was to compare Doppler echocardiography imaging with pulmonary artery thermodilution measurement during mechanical ventilation. Total 78 piglets (6 weeks old, average weight 24 kg, under general anesthesia) were divided into 4 groups under different cardiac loading conditions (at rest, with increased left ventricular afterload, with increased right ventricular preload, and with increased afterload of both heart ventricles). At 60 and 120 min the animals were examined by echocardiography and simultaneously pulmonary artery thermodilution was used to measure cardiac output.
