A comprehensive eye/vision program

As an essential element of the comprehensive rehabilitation efforts at Northport VA Medical Center, and as a service whose demand is projected to increase substantially with the expanding proportion of aging veterans, eye/vision care has become increasingly important. As a result, the administration of the Medical Center decided to heed the suggestions of Congress and the Director of Optometry in VA Central Office and reorganize the delivery of eye/vision services so the ever-increasing demand could be met more rationally, efficiently and effectively. In this paper, the Northport VA Medical Center's Comprehensive Eye/Vision Program, including the residency program in rehabilitative optometry, will be described and the benefits of the reorganization will be discussed.     

Diagnosis of traumatic cardiac contusion

Cardiac contusion following blunt chest trauma remains a diagnostic problem because of a lack of sensitive diagnostic tests. This study evaluated thallous chloride Tl 201 single-photon-emission computed tomography in a series of 48 patients following blunt chest trauma. Of the 48 patients, 23 had normal scans. None of these patients proved to have serious arrhythmias during three days of continuous monitoring. Of 25 patients with abnormal or ambiguous studies, five (20%) developed serious arrhythmias requiring therapy. Single-photon-emission computed tomography scanning thus was sensitive in indicating that group of patients at risk of serious arrhythmias, and may therefore prove to be a useful screening test to determine the need for hospitalization and arrhythmia monitoring following blunt chest trauma.     

Legal issues in complementary and integrative medicine. A guide for the clinician.

Physicians integrating CAM therapies into clinical practice face many legal challenges, including the fact that legal rules governing CAM providers and practices are new and evolving in many cases. Laws vary by state, and their application depends on the specific clinical scenario in question. As more evidence accumulates regarding safety and efficacy or lack thereof of specific therapies for given conditions, physicians will find clinical knowledge more abundantly mapped and that the parameters of liability are increasingly clear. Meanwhile, good clinical practice and a working knowledge of major legal rules can help provide physicians with a good measure of legal protection in situations involving integration of CAM providers and therapies in conventional medical practice.     

Long-term effects of cochlear implants in children.

OBJECTIVE: Since 1987, when the use of multichannel cochlear implants was initiated in children, candidacy has expanded; many thousands of children have received these devices, and results have revealed a wide range of performance. However, few long-term studies exist on a large population of these children. There have been concerns expressed that cochlear implant function might degrade over time, that devices and electrodes might migrate and extrude in the growing child, or that there might even be a deleterious effect of long-term stimulation of the cochlear nerve. The purpose of this study was to explore the long-term effects of implantation as a function of performance over time, reimplantation, and educational factors. STUDY DESIGN AND SETTING: We studied 81 children who received implants at a major academic medical center and were followed for 5 to 13 years. RESULTS: Results revealed significant gains in speech perception, use of oral language, and ability to function in a mainstream environment. There was no decrease in performance over time and no significant incidence of device or electrode migration or extrusion, and device failure did not cause a deterioration in long-term outcome. CONCLUSIONS: Multichannel cochlear implants in children provide perception, linguistic, and educational advantages, which are not adversely affected by long-term electrical stimulation.     

Haemophilus parainfluenzae complicating total hip arthroplasty: a rapid failure.

We present a case of rapid failure of a total hip arthroplasty caused by infection with Haemophilus parainfluenzae. The septic loosening occurred over a period of 3 months and followed a dental extraction that had not been covered by prophylactic antibiotics. This failure occurred in a previously well-functioning and asymptomatic prosthetic joint.     

Delusions of disfigurement in a woman with acne rosacea.

A 36-year-old woman with newly diagnosed acne rosacea is presented. Her skin changes were noticeable only under closest scrutiny, but she quit her job, became despondent about her acne, and developed suicidal ideation. The diagnosis and treatment of this patient allow a broader discussion of the somatically focused patient whose ideation reaches delusional intensity.     

Initial experience with a radiology imaging network to newborn and intensive care units

A digital image network has been installed in the James Whitcomb Riley Hospital for Children on the Indiana University Medical Center to create a limited all digital imaging system. The system is composed of commercial components, Philips/AT&T CommView system, (Philips Medical Systems, Shelton, CT; AT&T Bell Laboratories, West Long Beach, NJ) and connects an existing Philips Computed Radiology (PCR) system to two remote workstations that reside in the intensive care unit and the newborn nursery. The purpose of the system is to display images obtained from the PCR system on the remote workstations for direct viewing by referring clinicians, and to reduce many of their visits to the radiology reading room three floors away. The design criteria includes the ability to centrally control all image management functions on the remote workstations to relieve the clinicians from any image management tasks except for recalling patient images. The principal components of the system are the Philips PCR system, the acquisition module (AM), and the PCR interface to the Data Management Module (DMM). Connected to the DMM are an Enhanced Graphics Display Workstation (EGDW), an optical disk drive, and a network gateway to an ethernet link. The ethernet network is the connection to the two Results Viewing Stations (RVS) and both RVSs are approximately 100 m from the gateway. The DMM acts as an image file server and an image archive device. The DMM manages the image data base and can load images to the EGDW and the two RVSs. The system has met the initial design specifications and can successfully capture images from the PCR and direct them to the RVSs.(ABSTRACT TRUNCATED AT 250 WORDS)
