[Osteoarticular amyloidosis caused by dialysis].

The accumulation of amyloid in the bone and joint system has recently been recognized as a peculiar disease in patients undergoing long-term hemodialysis (5 years at least), especially in those who use cuprophan membranes. The pathology of amyloidosis is characterized by deposits of amyloid (beta 2-microglobulin mainly) in the bone, in the synovia, and in pericapsular soft tissues. The skeleton of 46 long-term hemodialysis patients (19 males and 27 females) was studied by X-ray: bone and joint abnormalities due to amyloid deposition were observed in 45% of cases. The shoulder, hip, and wrist were the most frequently involved joints. Destructive spondyloarthropathy was present in 15% of cases. The radiographic patterns of AOD are generally divided into axial and peripheral lesions. In the appendicular skeleton abnormalities include: well-defined lytic areas (geodes), pathologic fractures, marginal erosions, and periarticular soft tissue swelling. Destructive spondyloarthropathy is frequently present in the cervical spine (85% of our cases), and is characterized by narrowing of the intervertebral space, marginal erosion, and subchondral bone sclerosis of the vertebral body.

Genitourinary tuberculosis: the importance of early diagnosis and management. Case presentation.

Genitourinary tuberculosis is the second most common form of extrathoracic tuberculosis. The most common signs are persistent sterile pyuria in up to 90% of patients, irritative voiding symptoms and painless hematuria in up to 80% of the patients. In Puerto Rico the incidence of tuberculosis is rising, being 9.2 per 100000 population in 1992. A.I.D.S. has had a steady rise since 1983. With the rise in the incidence of both diseases and with the influx immigrants from countries were tuberculosis is endemic we should expect a rise in the number of cases of genitourinary tuberculosis. Chemotherapy is the mainstay of treatment. Surgery is performed less often. Early recognition and management is important to avoid irreversible damage to the genitourinary tract. The cases of a 43 y/o man and a 30 y/o male with A.I.D.S. are discussed.
