Muscle Histology in Rheumatic and Control Cases: A Study of One Hundred and Nineteen Biopsy Specimens.

Our conception of the pathology of rheumatoid arthritis has become modified as the result of recent studies of the Jwidespread changes taking place in the non-articular tissues in this disease. Gibson and others (1946) confirmed the work of Freund and others (1945) by showing that the affected tissues were all of mesodermal origin and that the lesions found in muscles consisted of a perivascula...

Mislabeling of cases, specimens, blocks, and slides: a college of american pathologists study of 136 institutions.

CONTEXT Accurate specimen labeling is a major patient-safety initiative by the Joint Commission and the College of American Pathologists. Inadequate specimen labels have led to patient injury from wrong patient diagnosis, wrong side treatment, and delay in diagnosis. OBJECTIVES To quantify the rates of mislabeled cases, specimens, blocks, and slides and to identify the sources of error and th...

Unusual findings in appendectomy specimens: Evaluation of 2458 cases and review of the literature

Simplifying collection of corneal specimens in cases of suspected bacterial keratitis.

Identification of the causative organisms in suspected bacterial keratitis traditionally involves collecting multiple corneal scrapes, which are plated directly onto different solid agar culture media. Difficulties have been reported with this practice, so the development of a simpler diagnostic method in suspected bacterial keratitis would be useful. It is unclear whether a single corneal scra...
