Time-oriented functional profile: practical applications in a stroke data-base model.

The feasibility of transferring data from a large computerized stroke data-base system (BUSTOP) to an existing time-oriented system of proven utility (ARAMIS) is demonstrated. Potential advantages of a time-oriented data-base system include: determination of prognostic indicators, suggestions for therapeutic intervention, analysis of experimental treatment programs, development of units of cost effectiveness and provision for uniform methods of auditing stroke care. This demonstration project shows that a large-scale stroke data-base system is feasible using existing computer models which are currently collecting and analyzing data-base statistics.

Asymptomatic hyperuricemia: the case for conservative management.

The management of asymptomatic hyperuricemia is controversial. Reported benefits from treatment prevention of acute gouty arthritis, chronic tophaceous gout, urolithiasis, or gouty nephropathy. A review of experimental and clinical data suggests that the risks of asymptomatic hyperuricemia are small or unknown and the efficacy of long-term treatment in preventing gout or renal disease is unproved. The costs and risks of prolonged drug administration and practical considerations such as patient compliance mitigate against long-term therapy in asymptomatic persons. We offer some recommendations for an expectant approach to the management of asymptomatic hyperuricemia.

Comparison of therapy in severe systemic lupus erythematosus employing stratification techniques.

Randomized studies, attempting to clarify the role of combined azathioprine and prednisone therapy versus prednisone alone in severe systemic lupus erythematosus have sustained rather than mollified a clinical controversy. No differences have been detected in some studies, while others have appeared to show benefit with addition of azathioprine. The present study suggests that neither small random trials nor uncorrected clinical experience can be expected to provide truly comparable control groups in conditions as variable as systemic lupus, but that stratification techniques can yield relatively similar groups. Patients meeting different entry characteristics are demonstrated to come to different outcomes. Depending upon the specifications of a subgroup, one therapy or another appears better.

Marginal benefit of renal biopsy in systemic lupus erythematosus.

The predictive information provided by renal biopsy was assessed for four systemic lupus erythematosus (SLE) patient populations and compared with the predictive information from clinical data without benefit of biopsy, both measured against actual outcome. Renal biopsy results, whether studied by light or electron microscopy, contain important prognostic information. However, the prognostic information from renal biopsies in these patient groups is generally less than that of even the simplest clinical classifications; and when combined with clinical information, the total prognostic content is essentially that of the clinical information alone. Thus, judged by presently available data, the renal biopsy in SLE provides mainly redundant prognostic information. The marginal benefit is the difference between what is known before and after a test. Quantitation of predictive accuracy allows assessment of marginal benefit, that is, the increment in accuracy afforded by an additional test. Costly and potentially hazardous procedures, such as renal biopsy, require reassessment in terms of marginal rather than absolute predictive ability.

Clinical history as a screening test for ankylosing spondylitis.

A controlled study of 138 subjects demonstrated that the clinical history may be sensitive (95%) and specific (85%) in the differential diagnosis of ankylosing spondylitis when reliance of five specific historic features is made. Back pain that is insidious in onset, in a patient younger than 40 years, persisting for at least three months, associated with morning stiffness and improving with exercise is characteristic of inflammatory spinal disease.

The close correlation between symptoms and disease expression in HLA B27 positive individuals.

Following demonstration that 20 percent of presumed "healthy" HLA B27 positive individuals develop symptomatic ankylosing spondylitis, a controlled follow-up assessment of the remaining "asymptomatic" 80 percent was performed. The clinical and radiological study revealed that there is a close correlation between symptoms and radiologic change in HLA B27 positive subjects; those individuals remaining symptom free have normal pelvic radiographs. Ankylosing spondylitis or "asymptomatic sarcroiliitis" does not exist in a subclinical manner throughout the entire group of B27 positive subjects. Evaluation of the pelvic radiographs of both symptomatic and asymptomatic HLA B27 positive subjects and symptomatic HLA B27 negative controls demonstrated that osteitis pubis and fluffy periostitis are equally distributed among the three groups, only the frequency of sacroiliitis being statistically greater in the B27 positive symptomatic subjects.
