Fukuyama congenital muscular dystrophy in two Australian female siblings.

The clinical course of two female siblings with congenital muscular dystrophy is briefly described, and includes congenital cerebral malformations consisting of pachygyria, polymicrogyria and white matter abnormalities. The first sibling died in infancy; the second is now 18 years of age. The changes found at autopsy in the first sibling are identical to MRI changes in the surviving sibling.

'Dialysis related arthropathy': a survey of 95 patients receiving chronic haemodialysis with special reference to beta 2 microglobulin related amyloidosis.

Ninety five patients receiving chronic haemodialysis (CHD) were surveyed to determine the prevalence of rheumatic disease and, where possible, its aetiology. At least three distinct rheumatic syndromes were identified--a group of patients with a syndrome consisting of large and medium joint synovial swelling, restricted hips and shoulders, tenosynovitis, carpal tunnel syndrome, and bone cysts due to deposition of beta 2 microglobulin related amyloid (AM beta 2m); a second group with erosive azotaemic osteoarthropathy; and a third group with age related degenerative disease of small, large, and axial joints. The data presented suggest that in patients receiving CHD (a) the prevalence of AM beta 2m deposition and the associated syndrome increases with duration of dialysis, but in patients who have been dialysed for more than 10 years the risk of developing AM beta 2m is related to age; (b) AM beta 2m deposition in subchondral cysts, but not synovium, causes joint destruction; also, AM beta 2m may be more prone to deposition in synovium of joints already damaged by other processes; (c) in the absence of synovial iron deposition synovial AM beta 2m is not associated with an inflammatory infiltrate; (d) hyperparathyroidism and perhaps other factors such as synovial iron deposition are probably more important than AM beta 2m as causes of peripheral joint degeneration and destructive spondyloarthropathy in patients receiving CHD.

Primary malignant tumors of the thyroid gland: a clinicopathologic study of 254 cases.

Of 254 primary malignant tumors of the thyroid gland diagnosed in the pathology department of the University of Cape Town, 212 (83.5%) were differentiated carcinomas. In this differentiated group, tumors composed exclusively of papillary structures exhibited the most favorable prognosis; local recurrences and/or spread were noted in tumors with a mixed papillary and follicular pattern and, more commonly association with 21 tumors (8.3%) but an associated multinodular goitre was found in only nine patients (3.5%). In addition to the well-known preponderance of thyroid carcinoma in women, a majority of lesions occurred in white patients in this series despite a higher hospital admission rate for coloreds (mulattos).

Virilization with diffuse involvement of ovarian androgen secreting cells.

A case is reported in which virilization of long duration and gradual progression was found in association with ovarian hyperthecosis and bilateral hilar cell lesions. The frequency occurrence of both masculinizing and nonmasculinizing ovarian tumors in association with ovarian hyperthecosis and polycystic ovaries is discussed.
