A case of crossing coronary arteries.

We present the case of a patient in whom coronary angiography, performed due to severe calcific aortic stenosis, revealed crossing between the left anterior descending artery and the first diagonal branch. There is only a single report presenting this particular coronary anatomy, whereas this is the eleventh case of crossing coronary arteries ever reported. The clinical implications of this variant coronary anatomy with regard to diagnostic angiography and selection of revascularization procedures are briefly discussed.

An unusual case of acute on chronic renal failure following percutaneous coronary intervention.

Contrast nephrotoxicity is a common and well-documented complication of procedures utilising x ray contrast medium. It should be looked for whenever patients are exposed to contrast medium as it carries a good prognosis if managed appropriately, with only a minority of cases requiring dialysis. It is essential, however, that other causes of renal dysfunction are excluded before making a firm diagnosis of contrast nephropathy.

Primary cardiac undifferentiated sarcoma of the right atrium presenting with cardiac tamponade.

This report illustrates the serial imaging of a primary cardiac undifferentiated sarcoma of the right atrium using echocardiography, chest X-ray, and computed tomography. Transthoracic echocardiography on presentation showed an extensive mass of the right atrial free wall with an impending cardiac tamponade. Symptoms were controlled with pericardiocentesis, pericardial window, and radiotherapy but recurred 8 months later with pleural effusion and tumor spread to the great arteries.

The incidence of type 1 diabetes mellitus in Greek-Cypriot children and adolescents in 1990-2000.

Objectives: To ascertain the exact incidence of type 1 diabetes mellitus (DM1) in Greek-Cypriots under the age of 15 yr, to analyze possible gender differences in the age of onset and to observe any seasonal variation in the manifestation of the disease.

Research Design And Methods: All cases of newly diagnosed DM1 patients under the age of 15 yr from 1990 to 2000 were collected and relevant information was obtained. The data were statistically processed in relation to the population data provided by the Department of Statistics and Research of the Ministry of Finance.
