Bipolar cautery and internal thermal sclerostomy in a rabbit model.

Internal thermal sclerostomy (ITS) was performed unilaterally in 35 adult New Zealand rabbits using a pinpoint bipolar cautery probe and radio-frequency power supply, with the nonoperated eyes serving as controls. Standard trabeculectomy using a limbal-based flap was also performed on 10 additional rabbits, and served as a second bench mark for comparison with the ITS technique. Intraocular pressure (IOP) was measured in all eyes preoperatively and on postoperative days 2, 4, 6, and 8. A significant (P = .005) difference between the reduction in IOP in the ITS eyes and in the control eyes was found up to postoperative day 8; on that day the reduction in IOP was 5.2 mm Hg. IOP in the eyes undergoing standard trabeculectomy was significantly (P = .05) reduced up to postoperative day 2, and gradually decreased, to 2.5 mm Hg, on postoperative day 8. The greatest reduction in IOP (2.9 mm Hg) for these eyes also occurred on postoperative day 2. Complications of ITS included iris burn (23%), peripheral corneal edema (17%), and iritis (9%). No ruptured blebs, flat anterior chambers, hyphemas, or lens damage occurred. The potential advantages of the ITS procedure using the bipolar cautery probe include a decreased risk of cataract formation because of the curved probe design. The procedure is also technically simple to perform and requires only inexpensive and readily-available equipment.

Prevalence of rheumatic diseases as causes of disability and complaints by ambulatory patients.

Data from the National Health Survey reveal that musculoskeletal diseases are the most prevalent cause of chronic disability among the civilian, noninstitutionalized population. Because of the frequency of musculoskeletal injuries, rheumatic disorders are the second most common cause of acute disability. Problems referable to the musculoskeletal system constitute the second most frequent class of complaints presented by patients to office-based physicians. Only respiratory and circulatory diagnoses are recorded more often by such physicians.

Clinical diagnosis of psychogenic rheumatism.

Rheumatic symptoms that are a somatic expression of emotional disturbance are common, and often are mistakenly attributed by physicians to organic disease. Psychogenic rheumatism is encountered most frequently among middle-aged women. The typical complaint is of widespread pain and stiffness, often with report of swelling and paresthesia, but symptoms characteristically are vague. Overt psychiatric disturbance may be apparent. Distinction from organic disease should not be difficult if physicians recognize the typical presentation, and find that symptoms fail to correspond to patterns of organic disorders. When organic disease coexists with psychogenic rheumatism, as often is the case, the objective abnormalities are insufficient to explain the symptoms.

Physical and occupational therapy for arthritic patients: a cooperative effort among hospital departments.

The importance of a team approach for optimum management of arthritis is recognized, but small hospitals and clinics may have difficulty supporting a team when the number of arthritic patients treated by any one department is not large. A cooperative effort of our 500-bed hospital's sections of rheumatology, physical medicine, and orthopedic surgery provides a physical therapist and an occupational therapist to work exclusively with arthritic patients. By working across departmental lines the therapists perform enough services to pay their salaries. Patients benefit not only from the availability of therapist specialists but also from continuity of care. Presence of the therapists has permitted extension of care to a satellite clinic and to patients' homes. The cooperating sections have acquired personnel and capabilities not available to them if acting independently.

A study of the optical micrometer, the coin gauge, and the diamond knife micrometer in diamond knife calibration.

Reproducible results in refractive keratectomy are greatly influenced by an accurate setting of the diamond knife blade length. In this study, we evaluated the accuracy and reproducibility of three existing techniques of blade calibration: the KOI coin gauge, the KOI diamond knife handle micrometer, and the Magnum optical micrometer. Serial blade length measurements of three similarly designed KOI diamond knives were made using each of the above calibration methods. The three knife handle micrometers had the largest measurement error (3.55%, 2.83%, 1.82%), and therefore the sole reliance of the handle micrometer for blade calibration was not recommended. The measurements made by the coin gauge on the three knives had measurement errors of 1.03%, 1.64%, and 1.46%. The optical micrometer achieved an accuracy of 0.005 mm and an interobserver precision of 0.009 mm. We prefer using the optical micrometer because the potential for parallax error is eliminated; it has a lower risk of blade damage; it is easier to use; and it also allows detection of defects in the footplates, the diamond knife, and of the wobbling blade, which may contribute to calibration error.
