Renin in Wilms' tumor: prorenin as an indicator.

In a prospective study, 25 children with nephroblastoma (Wilms' tumor) had preoperative plasma prorenin and renin concentrations measured. The mean plasma renin and prorenin concentrations in the patients were raised compared with a control group of patients without nephroblastoma. Four children had recurrence of tumor and, in three, this was associated with an increase in plasma prorenin concentration. Nephroblastoma tissue contained immunoreactive renin and renin messenger RNA, and the renin protein was immunologically and biochemically similar to normal human renin. We conclude that prorenin concentrations in plasma are an indicator of nephroblastoma.

A prospective survey of radiological bone and joint changes in primary biliary cirrhosis.

A prospective survey of radiological bone and joint changes was undertaken in 42 patients with primary biliary cirrhosis (PBC) and 23 patients with alcoholic or cyptogenic cirrhosis who formed a control population. PBC patients were commonly found to have hypertrophic osteoarthropathy (38%), joint erosions (31%) and osteoporosis, these results being significantly different from the control group. Hypertrophic osteoarthropathy most frequently affected the first metacarpal and was rarely associated with finger clubbing or clinical symptoms. Joint erosions were most evident in the hands, often associated with a positive rheumatoid factor but only accompanied by symptomatic arthritis in four cases. Patients with PBC show a high prevalence of symptomless bone and joint changes which may become manifest clinically only as the disease progresses; radiography of the hands is recommended as a screening test for these changes.
