[Angioedema: first manifestation of non-Hodgkin's lymphoma].

Angioedema can be hereditary or acquired. Hereditary angioedema is a genetic disease transmitted with an autosomal dominant mechanism. Acquired angioedema usually occurs after the second decade of life and is often related to an underlying disease.

[Aneurysms of the common trunk, anterior descending and right coronary artery in a 33 years old man with acute myocardial infarction. A case report].

Coronary artery aneurysms are often incidental findings during coronary angiography; they are mostly secondary to atherosclerosis or vasculitis, they are rarely congenital. Right coronary circumflex and anterior descending arteries are usually involved but only few cases of aneurysms of left main coronary artery are reported. A case of coronary artery aneurysms is described involving left main, right and anterior descending coronary arteries, probably secondary to atypical Kawasaki disease in a 33 years old man with acute myocardial infarction.

[Tophaceous gout in plurimetabolic syndrome].

Aim of this paper is to describe and discuss, on the basis of the available current literature, the case of a female patient affected by a tophaceous gout associated with plurimetabolic syndrome. Hyperuricemia and gout may be seen today in all the populations of developed countries, with increasing frequency on the last fifty years. Increased production or reduced urinary excretion of uric acid (and hypoxanthine and xanthine) are the most important pathogenetic mechanisms of primary or secondary hyperuricemia.

Significance of microalbuminuria in atherosclerotic vascular disease.

Microalbuminuria is considered as a sign of high risk of renal disease in type 1 diabetes mellitus, and of cardiovascular disease in types 1 and 2 diabetes. In recent years numerous studies have suggested that microalbuminuria may be associated with atherosclerotic vascular disease, independently from diabetes mellitus. The presence of microalbuminuria was investigated in 30 patients suffering from atherosclerotic vascular disease: ischemic heart disease, cerebrovascular disease or arterial disease of the lower extremities.
