RESUMO

BACKGROUND: The difficulties in reaching a good level of oral hygiene in young babies can be partly overcome with the use of baby oral wipes, which have been shown to effectively remove plaque from deciduous teeth. The presence of fluoride and calcium in these wipes could also prevent further demineralization of the teeth, as well as promote remineralization. The aim of this study is, therefore, was to analyze the preventive effect of OW containing F and CaGP on cariogenic demineralization in vitro. METHODS: For this, seventy enamel samples were treated with OW soaked in solutions containing different F concentrations (250 ppm; 500 ppm and 1500 ppm) with or not with 0.13% CaGP and distilled water for the control group. The samples were submitted to an 8-day cariogenic pH cycling. The experimental solutions were applied twice per cycle, by immersing a dry inert oral tissue into 4 mL of the solution and rubbing it over the enamel surface. Enamel microhardness was measured initially and after the experimental cycles. Environmental scanning electron microscope was taken to visualize and quantify elements on the enamel surface. RESULTS: No significant difference was observed (P=0.694), but when the groups containing CaGP were compared to the negative control solution, a significant difference was found. CONCLUSIONS: The presence of 0.13% CaGP and fluoride in concentrations greater than 500 ppm were able to provide protection of dental enamel against demineralization.

RESUMO

This case report describes the esthetic dental treatment of a patient with Cohen syndrome where microabrasion was used to treat dental fluorosis. The patient's teeth had white and light yellow spots, which were diagnosed as moderate dental fluorosis. These spots were treated with microabrasion using pumice paste and 37% phosphoric acid. The paste was applied with a rubber cup on a low-speed handpiece and manually using a wooden stick. It took four appointments to treat all of the patient's teeth. Topical neutral fluoride was applied after each appointment to decrease any dental sensitivity. The esthetic result was satisfactory. Esthetic dental treatment may result in positive emotional and behavioral changes in patients with special needs.

RESUMO

Hemangiolymphangioma is a mixed vascular malformation that is detected in the prenatal period by sonography. Five cases of prenatal diagnosis have been reported that have resulted in termination of pregnancy (two) or aggressive versus purely surgical post-natal management. We present the case of an infant with pre-natal diagnosis of a multicystic intra-abdominal mass that received surgical management followed by conservative treatment.

RESUMO

Prenatal sonographic evaluation is of utmost importance in the detection of congenital anomalies. At the Ultrasound Section of our Radiology service, we incidentally detected fetal intracranial neoplasms in two different patients using non-invasive imaging. Our presumptive diagnosis in both cases was a teratoma, the most common brain tumor in the perinatal period. Subsequent confirmation was provided with pathological samples obtained at autopsy in both patients, revealing immature teratomas. Fetal intracranial tumors are so rare and incredibly, these two unique cases presented in our section within just a few months of one another.

RESUMO

Immunohistochemistry has revolutionized the field of diagnostic pathology in the past fifteen years. Since then, it has been increasingly used as an adjunct to morphological diagnosis. The purpose of this retrospective analysis is to examine the value of this technique in the diagnosis of pediatric neoplasias in our laboratory. Forty eight pediatric cases, collected from January 1998 until May 1999, were reviewed, and classified in one of four categories: confirmed the morphological diagnosis, provided the definite diagnosis from a list of probable diagnoses, contributed by excluding other entities, and non-contributory. Immunohistochemistry confirmed the morphological diagnosis in 29 cases (60.4), provided the definite diagnosis from a list of probable diagnoses in 13 cases (27.1), was contributory by exclusion of other entities in 2 cases (4.2), and was non-contributory in 4 cases (8.3). In this preliminary study, we conclude that immunohistochemistry is being used in our laboratory mostly as a confirmatory tool for the definitive diagnosis of the lesions and once more exalts the utility of this technology in the field of diagnostic pathology.
