Avaliação in vitro do aparelho DIAGNOdent para diagnóstico oclusal

The aim of this study was to determine the effectiveness and reliability of laser fluorescence measurements in relation to occlusal caries diagnosis. DIAGNOdent 2095 (Kavo, Biberach, Germany), which has been developed especially for caries diagnosis, was utilized. Five (5) teeth were examined in the pilot test; after that, ten (10) teeth were examined in order to calibrate both examiners. Data were obtained from 66 teeth (36 molars and 30 premolars), totalizing 144 sites identified through photographs of the occlusal surfaces. Reproducibility was evaluated in 10 teeth. The interexaminer Spearman correlation (r) was 0.89 and the intra-examiner, 0.93 and 0.97 (examiner A and B, respectively). Validation was carried out by histological examination (stereomicroscope). For the two examiners the sensitivity of the device was relatively high, varying from 0.81 to 1.00, while specificity varied according to which validation criterion was used (0.77 - 0.86: enamel lesion / 0.52 - 0.59: dentin lesion). It was concluded that DIAGNodent presented good capacity of identifying any alteration of the dental surface, nevertheless it presents the disadvantage of accomplishing many false-positive diagnosis when the validation criterion is dentin lesion.

Prevalência de pterígio no município de Botucatu - Estado de São Paulo, Brasil

PURPOSE: To evaluate the prevalence of pterygium in a population-based sample at Botucatu City - São Paulo State, Brazil. METHODS: A population-based cross-sectional study with randomized clustered sampling of households was conducted in the urban area of the Botucatu City -São Paulo State, Brazil and 85.1% of the intended sample was evaluated. All participants were submitted to ophthalmologic examination and the data were statistically analyzed. RESULTS: The prevalence of pterygium lesion in Botucatu City was 8.12% (7.0% < CI < 9.2%), affecting mainly males (10.4% males X 6.5% females - 8.5% < CI < 12.3% for males and 5.1% < CI < 7.8% for females) with 49.6 ± 14.9 years old in average; 32.18% of the pterygium carriers aged between 40 and 50 years. CONCLUSIONS: The prevalence of pterygium at Botucatu is 8.12%, affecting most frequently 40-50 year-old males.

Aneurisma gigante da artéria cerebral média

A case of giant aneurysm of the left middle cerebral artery, in a 28-year-old right-handed woman, successfuly operated is reported. The aneurysm measur- ing 35 x 27 x 23 mm showed clinical manifestations as a space-occupying lesion. The patient recovered completely after the total excision of the aneurysm.

Aspecto tumoral da cisticercose intracraniana: abordagem cirúrgica

The cerebral cysticercosis can produce intracranial hypertension by inflammatory obstruction of the basal cysterns or by expansive lesion in the cerebral parenchima or ventricular cavities. In the latter and in tumor cases the clinical picture is very similar and only after surgery can the etiology be determined. We present 11 operated cases of intracranial cysticercosis which presented the clinical picture of an expansive lesion. There were 7 females and 4 males with ages between 4 and 65 years. Nine patients were admitted because of headache, vomiting and visual disturbances suggestive of intracranial hypertension. One patient was admited with lymphocytic meningitis and another with focal seizures following hemiparesis. Five patients presented focal signs and six edema of the papilla. Epileptic manifestations were present in 45.5% of the cases. A plain X-ray films of the skull failed to reveal calcificatons, however signs of chronic hypertension were present in three cases. The electroencephalogram showed slow focal waves in 8 patients The spinal fluid examination revealed lymphocytosis in 4 cases, increased protein content in another 4 and complement fixation for cysticercosis was positive in 2 cases. The expansive lesions were localized by angiograph and ventriculography. In these the location was temporal in 4, frontal in 3, parietal in 2, in the third ventricle in one and in the fourth ventricle in another. At surgery we removed a large cyst from the cerebral parenchyma in six cases. Around the cyst a thick glial reaction was present. In the other cases the cyst was small but fixed to the ventricular trigone and produced dilatation of the inferior horn of the lateral ventricle. In two cases we removed a solitary intraventricular cyst from the third and fourth ventricles. In the two children operated upon there were several small hard cysts involving the cerebral parenchyma which displayed intense gliosis. There were no postoperative complications.

Astrocitoma frontal com metastase medular: registro de um caso e revisão da literatura

A case of a right frontal astrocytoma with spinal metastatic lesion in the region of the third dorsal vertebra is reported. The metastatic nodule was removed six months after the craniotomy. In the literature concerning to the dissemination of tumors cells is suggested that there is not a causal relationship between CSF seeding and operative intervention. Acess to the ventricular system or basal cisterns is of primary importance in the production of metastases.
