Abstract

Injuries, particularly linear fractures of the radial head, may be difficult to detect in the routine radiographic study of the elbow (1). Kulowski (4) has expressed the need for more accurate diagnoses in elbow fractures. Meschan (8), without elaborating, has stated that the periarticular soft tissues may show evidence of swelling. Norell (9), in an excellent observation, has described fat pad displacement about the humeral fossae in the presence of fractures involving the elbow joint, although he erroneously described the fat as “extracapsular.” A survey of the American radiological and orthopedic literature fails to reveal any report of this “fat pad sign.” The purpose of the present paper is to show that the pads described by Norell are “extrasynovial” and “intracapsular,” and to demonstrate further their value in radiographic interpretation of obscure elbow joint injuries. Displacement of these pads can also be of aid in evaluating the elbow in those local and generalized disease processes which resu...

Abstract

A modified thyroid-stimulating hormone (TSH) radioimmunoassay with particular sensitivity at the bottom end of the normal range was developed using dog serum in standard tubes and reduced quantities of TSH labeled with radioactive iodine (125I) and antiserum. The standard deviation of B0 points was 1%, implying an assay sensitivity of less than 0.1 microU/mL. This procedure was used to measure serum TSH levels in 32 normal subjects, 18 patients with hyperthyroidism, and seven patients with elevation of serum triiodothyronine (T3) levels. The range of values obtained from normal subjects was less than 0.1 to 4.1 microU/mL, with 97% of the subjects' values greater than 0.2 microU/mL. All of the hyperthyroid patients had values less than or equal to 0.2 microU/mL. Hence, the modified TSH assay was thought to be of use in distinguishing hyperthyroid from normal subjects. The TSH levels in subjects with elevated T3 levels ranged from less than 0.1 to 1.8 microU/mL. These results were thought to indicate heterogeneity within this group and suggest that only certain of these individuals merit the diagnosis of "T3 toxicosis."
