[Neuroendocrine tumours of the upper gastrointestinal tract, characteristics and comparison of localization diagnostics].

In daily clinical practice it's important to think of neuroendocrine tumors, since their prevalence for the past 5 years exceeded even the common occurrences of stomach, esophageal and pancreatic cancers. Patients diagnosed early and accurately with NET, have a greater chance for complete cure. The diagnostic tools over the past century were significantly inefficient in diagnosing NET i.

[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%).

[Single-photon emission-computed tomography in the diagnosis of cerebrovascular diseases].

Background: SPECT-HM-PAO allows to detect the regional cerebral blood flow and total diminution of the brain perfusion still before morphological substrate evolution in CT scan, without invasive technologies. SEARCH GOAL: The authors have analyzed data obtained by SPECT-99mTc HM-PAO in the group of 46 patients suffering from cerebrovascular disorders and they have compared them with results aimed by CT scans. Both, the SPECT-99mTc HM-PAO and CT scan were performed within 48 hours or later after the onset of the stroke; some of CT scans were repeatedly performed.
