ABSTRACT
A 62-year-old woman presented with massive right-sided hydrothorax associated with cirrhosis of the liver. Chest scintigraphy after intraperitoneal injection of labelled tracer showed movement of the tracer from the peritoneal to the pleural cavity. Medical therapy and thoracocentesis were successful in this case.

This report concerns the history of a portugesian family including one case of MEN II a (female, born 1932, presenting medullary carcinoma of the thyroid--MCT--, hyperparathyroidism and suspected pheochomocytoma), and three others with MCT alone or in association with pheochromocytoma. The diagnosis of MCT has been made possible investigating six members of the kindred by use of IR - calcitonin measurements and pentagastrin injection. This provocative screening test is also of interest to follow operated patients.

Thallium-201 scintigraphy of the exercised myocardium was performed in 70 male patients admitted for coronary arteriography and left-ventricular angiography. Left ventricular scintigrams were collected in left lateral, left anterior oblique (65 degrees, 45 degrees, and 25 degrees), and anterior views, and the images were divided into eight segments: apical, anteroseptal, anterior, antero-lateral, posterolateral, posterior, inferior, and posteroseptal. A correlative study between segmental hypoperfusion on scintigram and coronary-artery stenosis visualized by contrast artriorgraphy allowed selection of specific segments for each main coronary artery. Hypoactivity in the apical and posterior segments did not appear reliable. Using selected segments, we were able to identify LAD disease in 84%, LCx disease in 49%, and RCA disease in 79% of documented significant stenosis, with specificity of 95%, 89%, and 88%, respectively. Coronary-artery disease could be detected in 95% of patients having more than 50% coronary-artery stenosis, with 93% specificity. In most cases, patients with two-vessels disease and three-vessel disease could not be distinguished from each other. Multiple-vessel disease suggested by segmental analysis of myocardial scinitgrams after exercise was confirmed artriographically in 88% of the patients, but 52% with scintigrams suggesting signle-vessel disease had, in fact, multiple-vessel disease.

Radiocardiography provides a simple method of measurement of blood volume, cardiac output, mean pulmonary circulation time, and pulmonary blood volume. The use of a computer allows the results to produced immediately provided that the circulating blood volume is measured during the test anpd that the radiocardiographic tracing is analysed by an entirely automatic method. The reproducibity of the results given by this automatic method has been studied in 35 patients, two measurements being made at 20 minute intervals. The standard deviation of the percentage difference between consecutive measurements was 5.8% for the blood volume, 10.4% for the cardiac output, 8.8% for the mean pulmonary circulation time, and 9.7% for the pulmonary blood volume.
