OBJECTIVES To assess visual inspection with acetic acid (VIA) as a screening tool for use in a well-equipped health center in Peru, to evaluate VIA as an alternative or adjunct to the Papanicolaou (Pap) smear, and to determine if VIA can play a role in settings other than low-resource ones. METHODS This was a prospective study of 1 921 asymptomatic women(More)
Hearing conservation or gain are important parameters of tympanoplastic surgery. The frequency of this surgical procedure and the difficulty in obtaining tissues due to the increased risk of H.I.V. transfer has made the use of synthetic products somewhat more acceptable in contrast with the use of organic substances (homograft ossicles, bone, cartilage and(More)
Tympanoplasty does not resolve problems such as tympanic reconstruction, pneumatic cavity and ossicular transmission mechanism. With the purpose to solve these problems, we used autografts of tragal cartilage with its perichondrial membrane. In just one surgical procedure, we built a transmission mechanism and a consistent new tympanic membrane. Results(More)
We have carried out a retrospective study of 110 ears in patients affected with otosclerosis who underwent revision of stapedectomy, from 1979 to 1991, because they did not achieve hearing improvement or still presented persistent dizziness after primary stapedectomy. In our series, the most common causes of surgical failure after the first surgery are:(More)
UNLABELLED The controversy regarding the best procedure for treating middle ear cholesteatoma has lasted over 100 years. This paper discusses our current methods for dealing with cholesteatoma, always through external ear or transmeatal mastoidectomy. We present the results of three years of follow-up. MATERIAL AND METHODS A prospective study was made of(More)
Ocular spectroscopy, which is the use of the eye to monitor optically the concentration of metabolites in the body, has been successfully applied to monitor aqueous humor glucose concentration. In the United States, 1.7 million intraocular lenses are currently implanted yearly. Because patients with diabetes are more likely to develop cataracts at an(More)
