[Diagnosis of the Zollinger-Ellison syndrome. I: Significance of anamnestic, clinical and laboratory examinations].

The authors describe the diagnostic algorithm of Zollinger-Ellison's syndrome which proved useful in the diagnosis of 73 patients with a confirmed diagnosis. They evaluate the diagnostic validity of anamnestic and clinical data, of different examination methods and compare them with experience assembled abroad. For the diagnosis of sporadic gastrinomas the onset of the disease after the age of 40 years is important, the development of serious peptic complications (haemorrhage F-70%, M-59%, perforation M-54%, F-47%) and the presence of watery diarrhoea (41%).

Hypoplastic intrapulmonary vascular system with multiple peripheral stenosis of the pulmonary artery.

A case history is reported of a nine-years-old girl with a hypoplastic intrapulmonary vascular system and with multiple peripheral stenoses of the pulmonary artery. The clinical, laboratory, and X-ray symptoms of peripheral stenoses of the pulmonary artery are described. The haemodynamic effects of peripheral stenoses of the pulmonary artery on the pressure tracing recorded from the pulmonary artery trunk are analyzed.
