Abstract

The Authors report the results of a renal morphological study carried out on eight patients with chronic lead poisoning. The ultrastructural analysis showed changes, mainly involving the proximal tubules, as follows: 1) degenerative pattern (swollen mitochondria, dilated endoplasmic reticulum and scanty microvilli); 2) signs of metabolic hyperactivity (intranuclear granular inclusions, odd shaped nuclei); 3) regenerative pattern (poorly differentiated cells with few microvilli, shallow infoldings of basal cell membranes). In the glomeruli the most characteristic finding was a mesangial reaction. The basement membrane, in some cases, appeared to be thickened and the visceral epithelial cells hypertrophic. Interstitial fibrosis was present, as well as, occasionally, a certain degree of arteriolar hyperplasia. These data appear to confirm that chronic lead nephropathy has an extremely slow evolution.

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
