Auscultatory and echocardiographic and phonocardiographic studies were performed on 26 patients who had a total of 11 Lillehei-Kaster, 16 Björk-Shiley, and 18 St Jude heart valve prostheses functioning normally in the aortic or mitral positions or both. With all types and positions of prostheses a distinct closing sound was always detected. It was frequently heard in two parts which, according ...

OBJECTIVE This paper reports on the long-term outcome of patients with Kennedy Class IV partial edentulism treated in the Implant Prosthodontic Unit (IPU) at the University of Toronto, Toronto, Ontario. METHODS The information for this paper was gathered from the charts of the first 30 consecutive, partially edentulous patients treated at the IPU. These patients all had Class IV edentulism an...

Objective To show the relationship between dental prostheses and the incidence and type of oral lesions developed in the Seridó region of Brazil. Methods 77 patients were registered. All were over 21 years of age, of both sexes, non-alcoholic and / or chronic smokers, and residents of the municipalities of the region corresponding to Seridó. They also all had some type of oral lesion and had be...

The survivorship oftotal hip replacements in patients operated on at the Royal National Orthopaedlc Hospital has been analysed using standard actuarial methods. Between 1%3 and 1972 173 metal-on-metal prostheses of various developmental designs were inserted. Between 1969 and 1972 248 prostheses of one design using a metal femoral component and plastic cup were used. The patients were surveyed ...

Color matching to the surrounding skin is extremely important in patients wearing maxillofacial prostheses. It is of utmost importance to know the different techniques of color matching and coloring in maxillofacial prostheses. The purpose of this study is to review the literature data with regard to color matching in maxillofacial prosthetics. An electronic search of peer review restricted to ...

Most of current concepts for a visual prosthesis are based on neuronal electrical stimulation at different locations along the visual pathways within the central nervous system. The different designs of visual prostheses are named according to their locations (i.e., cortical, optic nerve, subretinal, and epiretinal). Visual loss caused by outer retinal degeneration in diseases such as retinitis...

No random surveys have been done to determine how effectively veterans with amputation can utilize their prostheses, and only one limited survey has been done of Scandinavians' use of lower-limb prostheses. A pilot survey of prosthetic problems was sent to all 170 US veteran soldiers who had traumatic amputations over the last 10 years, whose addresses could be supplied by the VA, and whose med...

Fracture of hip prostheses is a rare occurrence. A case of bilateral hip prostheses fracture is described here. The need to follow-up and remain vigilant post hip replacement is highlighted.

INTRODUCTION Over 80% of patients with esophageal cancer are qualified only for palliative treatment. The main goal of the therapy is to eliminate symptoms of dysphagia. AIM To analyze complications after insertion of prostheses and stents in patients with inoperable cancer of the esophagus/cardia. MATERIAL AND METHODS From 1996 to 2015 prostheses of the esophagus were implanted in 1309 pat...

Marginal gaps, overhanging frameworks and residual cement result in plaque accumulation, finally leading to peri-implantitis. The aim of this study was to radiographically evaluate marginal adaptation, residual cement and overhanging frameworks in implant-supported fixed prostheses. In the present descriptive/cross-sectional study, 96 implant-supported fixed prostheses fabricated and delivered ...
