Simple devices for the physically disabled.

A report is given on a number of devices for the disabled that have been developed in the Biomedical Engineering Department at the Mississippi Methodist Rehabilitation Center. The primary criteria used in selection of devices to be included use simplicity, ease of fabrication and low cost.

Distancing for intimacy in lesbian relationships.

The authors present a collaborative treatment model designed to help the closely merged, troubled lesbian relationship. Therapeutic techniques focus on change in territorial, temporal, monetary, cognitive, emotional, and environmental space. A case example illustrates the interventions, which include individual and conjoint work, collaboration between therapists, education, bibliotherapy, referral to gay community resources, and specific suggestions for behavior change. The therapeutic goal is to restore intimacy to the relationship by offering each partner increased distance, personal space, and individual autonomy.

Mitral valve aneurysm: clinical features, echocardiographic-pathologic correlations.

Aneurysm of the mitral valve occurs most commonly in association with infective endocarditis of the aortic valve. The probable mechanism of its formation is destruction of the aortic valve which results in a regurgitant jet that strikes the anterior leaflet of the mitral valve, creating a secondary site of infection leading to the development of an aneurysm. Perforation of these aneurysms may occur, resulting in mitral regurgitation and pulmonary edema from a ventricle already volume overloaded from aortic regurgitation. This report describes the clinical and echocardiographic-pathologic findings in five patients with pathologically proven aneurysm of the mitral valve. There are no clinical features that appear specific for this abnormality. The two-dimensional echocardiographic feature that is helpful in the diagnosis is a bulge of the mitral valve leaflet toward the left atrium that persists throughout the cardiac cycle. Preoperative diagnosis is important because a mitral valve aneurysm may produce serious complications and is frequently overlooked during surgery. Repair of the aneurysm may be feasible; otherwise, valve replacement becomes necessary. Careful two-dimensional echocardiographic examination should be done in patients with left-sided infective endocarditis to detect an aneurysm of the mitral valve.

Isolated chronic tricuspid insufficiency due to closed chest trauma: report of a case with long-term follow-up.

A case of isolated chronic tricuspid insufficiency due to closed chest trauma is described in this report. Studies for carcinoid syndrome were negative. At surgery the posterior leaflet of the tricuspid valve appeared to be torn and disrupted. The other leaflets were shortened and atrophic. The results of pre- and postoperative cardiac catheterization with long-term follow-up to the present, and the available literature on this rare entity has been briefly reviewed.

Surgical management of the small aortic annulus. Hemodynamic evaluation.

Replacement of the aortic valve can be accomplished with ease and safety in most instances. The presence of a small aortic root, however, remains a problem in that both mechanical and stent-mounted tissue valves produce higher resting gradients in the smaller sizes. To avoid this, a technique has been developed to enlarge the aortic annulus. In a series of 253 patients undergoing aortic valve replacement, 22 required division of the aortic annulus. Extension of the incision inferiorly to the anterior leaflet of the mitral valve and a resulting separation of the annulus facilitated implantation of a larger valve. The resulting defect is obliterated with a woven Dacron patch. Hemodynamic data obtained on 12 patients who had recatheterization one to ten months postoperatively disclosed an average resting transvalvular gradient of 13.5 mm Hg. This procedure has been used successfully in combined aortic and mitral valve replacement and heart block has not occurred. Based upon encouraging follow-up studies of the Hancock glutaraldehyde-stabilized porcine heterograft, we use this prosthesis in patients with annular diameters of less than 25 mm. Our experience suggests that enlargement of the aortic annulus is necessary in a significant number of patients undergoing aortic valve replacement.

Techniques and complications of esophageal foreign body extraction in children and adults.

To assess the success rates and complications of esophageal foreign body extraction in adult and pediatric patients, the charts of 76 adults and 116 children with endoscopically or radiographically documented esophageal foreign body impaction were retrospectively reviewed. Success rates for rigid esophagoscopy (100%) and flexible endoscopy (96.2%) were not significantly different (p > 0.05). Overall, rigid esophagoscopy had a higher complication rate than flexible endoscopy (10% versus 5.1%, p > 0.05), but this trend did not reach statistical significance. The Foley catheter technique was used predominantly in children with proximally located blunt objects. Our study shows that flexible and rigid esophagoscopy are both safe and effective methods of removing esophageal foreign bodies, but rigid esophagoscopy carries a higher complication rate and therefore should be reserved for patients in whom flexible endoscopy is unsuccessful. The Foley catheter technique is suited only for proximally located blunt objects, and its routine use is not recommended.
