Audiometric configuration as a reflection of low plasma glucose and diabetes.

Forty-five subjects with a rising, progressively improving (RPI) audiometric pattern were considered for a 5-hour oral-glucose tolerance test. Results revealed that 2 nondiabetic subjects (4%) had a plasma glucose nadir of 49 mg/dl or lower and 7 nondiabetic subjects had a nadir between 50 and 57 mg/dl. A total of 21% of 42 subjects with data indicated abnormally low readings. An additional 7 subjects were found to be diabetic; 5 subjects had impaired glucose tolerance, and 9 other subjects had nondiagnostic glucose intolerance, totalling 47% of 45 subjects in the study with abnormally elevated plasma glucose levels. Therefore a total of approximately 68% of all subjects in our study indicated metabolic dysfunction based specifically on a RPI pattern.

Audiometric configuration as a reflection of diabetes.

The purpose of this study was to investigate whether or not a rising, progressively improving (RPI) sensorineural hearing loss from lower toward higher frequencies might be related to or serve as an indicator or predictor of diabetes. Forty-five subjects between the ages of 21 and 79, demonstrating a RPI audiometric pattern, were considered for a 5-hour oral glucose tolerance test. Based on the National Diabetes Data Group standard, results showed that diabetes mellitus appeared in seven subjects; five subjects had impaired glucose tolerance; and nine subjects had mild but nondiagnostic glucose intolerance. Relatively normal glucose values were demonstrated by 53% of subjects. There may be some value in an RPI audiometric pattern as an indicator or early detection sign for diabetes, but further research is necessary before such conclusions can be drawn.

Temporomandibular joint surgery: results of a 14-year joint implant study.

This paper analyzes the surgical techniques that are now used in treating organic temporomandibular joint (TMJ) disease. The authors attempt to evaluate the high condylectomy procedure which has been recommended by one group as the only surgical approach. In particular, the authors describe their experiences in using metallic and/or metal and plastic prosthetic devices for repairing damaged joints. The procedure used most frequently is a form of joint resurfacing, although total TMJ replacement is also described. On January 9, 1978, 205 questionnaires were mailed to patients who had undergone TMJ implant surgery. The population surveyed, representing 314 TMJ procedures, were asked to make a subjective overall assessment of the surgical result, and to rate the improvement, elimination, or worsening of each of 22 surgical indications (whenever such indications were applicable to themselves). The survey was done by the Clinical Research Division of a major company in the orthopedic field. The authors did not see the results of the evaluation until they were computed and analyzed by this independent group.(ABSTRACT TRUNCATED AT 250 WORDS)

Self-induced orbital emphysema as a presenting sign of Munchausen's syndrome.

A bizarre case of severe, debilitating pneumo-orbit resulting in proptosis, blindness, and eventual exenteration of the right eye and threatening the same fate for the left eye was worked up painstakingly for over 10 years before a final diagnosis of Munchausen's syndrome was uncovered. Five days after the diagnosis was made and appropriate management was instituted the severely proptotic left eye had returned to normal and the patient was discharged for out-patient psychiatric follow-up. A discussion of the differential diagnosis of pneumo-orbit is presented and Munchausen's syndrome, the final diagnosis in this case, is discussed from both an historical and psychiatric perspective.

Clinical evaluation of TMJ arthroplasties with insertion of articular eminence prosthesis on ninety patients (an eight year study).

This paper represents an analysis, accomplished over an eight-year period, of 90 individuals who have been operated on for various arthritic diseases of their temporomandibular joints (TMJ). In arthritic changes of the joint, several changes may occur: perforation of the disc, flattening of the articular eminence, asymmetrical condylar movement, and chronic synovitis. This may result in increased synovial pressure on nerve fibers within the capsule of the joint, and a variety of referred pain symptoms. Prior to operation, a careful differential diagnosis was made by an otolaryngologist and, frequently, by a neurologist/neurosurgeon and a psychologist. The prosthesis inserted during surgery was a metallic device which fits over the articular eminence in the upper portion of the joint. This prosthesis accomplished primarily three functions: elimination of the crepitus; restoration of the contour of the eminence; separation of the articular surface of the joint.
