Scoliosis

A lateral curvature of the spine occurring in association with actual rotation of the vertebral body and spine, in the direction of the concavity of the curve.There is wedging of the vertebral body and discs.The resulting prominence of the posterior part of the ribs on the side of the convexity may give a false impression of kyphosis. Scoliosis can be broadly divided into three categories, the commonest of which is the idiopathic form. Otherwise, scoliosis may be congenital, or may develop as a...

Alkaptonuria

An autosomal recessive disease, in which there is reduced activity of homogentisic acid oxidase, so that homogentisic acid cannot be metabolised. Ochronosis (the presence of brown black pigment), which is caused by abnormal accumulation of oxidised homogentisic acid, occurs in skin, connective tissue, and cartilage, including the cardiac valves. 1. The urine becomes dark, from homogentisic aciduria, after exposure to air or alkali.There is bluish discoloration of nails, auricles and axillae,...

Amyloidosis

Amyloidosis is a general term for a variety of different disease processes involving the deposition of fibrillary material in tissues.This is formed of protein subunits sharing a common beta-pleated sheet structure, but derived from proteins of great chemical diversity. These fibrils are resistant to normal proteolytic digestion and share a common histochemical staining property to Congo red. In the light of advances in the understanding of the structural chemistry of amyloid, the disease is...
