OBJECTIVE: To evaluate the positive predictive value for BI-RADS (Breast Imaging Reporting and Data System) categories 3, 4 and 5, correlating mammographic and histological diagnosis in non-palpable breast lesions. MATERIALS AND METHODS: Analytical-descriptive study of 169 women submitted to stereotactic localization for surgical biopsy of non-palpable breast lesions. Mammographic and histological findings were correlated, analyzing the predictive positive value for each category. RESULTS: Forty-two (24.8%) cases were diagnosed with breast cancer - only one in category 3, 19 in category 4, and 22 in category 5. The positive predictive value for categories 3, 4A, 4B, 4C and 5 were, respectively, 3.4%, 10.3%, 11.3%, 36% and 91.7%. Microcalcifications were the most frequent finding related to malignancy, present in 61.5% of these cases. CONCLUSION: The present study has demonstrated that BI-RADS allows a safe prediction of high suspicion of malignancy in lesions category 5 and low suspicion for category 3. As regards the category 4, the positive predictive value has shown a progressive increase in subcategories A, B and C, demonstrating that this subclassification represents an invaluable contribution for a more detailed and accurate assessment of lesions suspicious for malignancy.

Purpose: To establish the prevalence of refractive errors and ocular disorders in preschool and schoolchildren of Ibiporã, Brazil. Methods: A survey of 6 to 12-year-old children from public and private elementary schools was carried out in Ibiporã between 1989 and 1996. Visual acuity measurements were performed by trained teachers using Snellen's chart. Children with visual acuity <0.7 in at least one eye were referred to a complete ophthalmologic examination. Results: 35,936 visual acuity measurements were performed in 13,471 children. 1.966 children (14.59%) were referred to an ophthalmologic examination. Amblyopia was diagnosed in 237 children (1.76%), whereas strabismus was observed in 114 cases (0.84%). Cataract (n=17) (0.12%), chorioretinitis (n=38) (0.28%) and eyelid ptosis (n=6) (0.04%) were also diagnosed. Among the 614 (4.55%) children who were found to have refractive errors, 284 (46.25%) had hyperopia (hyperopia or hyperopic astigmatism), 206 (33.55%) had myopia (myopia or myopic astigmatism) and 124 (20.19%) showed mixed astigmatism. Conclusions: The study determined the local prevalence of amblyopia, refractive errors and eye disorders among preschool and schoolchildren.

PURPOSES: 1) To verify the impact of the creation of the Single Technical Record (STR) at the University of Campinas (Unicamp) Hospital das Clínicas, on the preservation period of corneas which were used in elective penetrating keratoplasties, and 2) to compare the primary failure incidence in cornea penetrating keratoplasties regarding the periods before and after the creation of STR. METHODS: A retrospective study was conducted at the Unicamp Hospital, which evaluated 15 consecutive cornea penetrating keratoplasties between January 1st and April 30th, 2000 and 24 consecutive penetrating keratoplasties between May 1st and September 20th of the same year (corneas under the control of the STR), totaling 39 keratoplasties. RESULTS: The mean time between cornea preparation and transplantation was 3.8 days (±1.78) in the period before STR creation, and 6.0 days (±2.97) after STR creation, representing a 36.7% increase in the preservation time. There was a statistically significant difference (p=0.02) between the two groups. No corneal primary failure was observed among the 39 transplanted patients in both groups. CONCLUSION: Based on the results of this study, it can be concluded that this new concept of the State Transplantation System has caused a statistically significant increase in the conservation period of corneas, which may reduce the period of a clear transplant due to an increased loss of endothelial cells, as well as increase the primary failure incidence or result in a high number of corneas that cannot be used due to having exceeded the preservation time recommended by the literature.
