Lupus erythematosus cell preparation-antinuclear factor incongruity. A review of diagnostic tests for systemic lupus erythematosus.

The cases of 20 patients, each of whom has a positive lupus erythematosus cell preparation and a negative antinuclear factor test, are presented. The concept of a false-positive lupus erythematosus preparation is suggested. Five common mechanisms causing a false-negative antinuclear factor test are discussed and evaluated. Clinical material from the 20 patients is described and pitfalls in diagnosing systemic lupus erythematosus are reviewed.

Approach to systemic vasculitis.

Systemic vasculitis is a confusing subject which has been difficult to classify and understand. Improvements in therapy increase the importance of early diagnosis. This paper reviews the clinical and pathological differences of the systemic vasculitides, and a working approach to the differential diagnosis of vasculitis is formulated based on the size of the vessel involved. Vessel size and histopathology determine to what group of diseases a particular syndrome belongs, thereby allowing subclassification and a more rational approach to management.
