Lixo Extraordinário e Estamira: exclusão e “delírios” entre história e ficção

Trabalho de Conclusão de Curso (Graduação)Jardim Gramacho, o maior aterro sanitário do mundo, fechado em 2012 é retratado em duas superproduções brasileiras, Lixo Extraordinário (2010) do artista plástico Vik Muniz, e Estamira (2006) do antropólogo e cineasta Marcos Prado. Dois filmes com panoramas distintos que relatam os problemas sociais do lixo, perpassando as questões da exclusão social, e da loucura. O primeiro documentário representa um coletivo de catadores que tiravam seu sustento nos materiais descartados pela sociedade, e no delinear de suas falas eram tecidos quadros que condiziam com suas trajetórias. O segundo apresenta as angústias de uma catadora esquizofrênica que viveu por 22 anos no aterro, e que cria um discurso messiânico e resistente em torno da realidade que viveu. Neste trabalho delinearei em meio às escolhas cinematográficas de cada obra as injustiças sociais percebidas naquele local, bem como as relações de poder que descartam os materiais e seres que acreditam serem desvalidos

Cemento-Osseous Dysplasias: Imaging Features Based on Cone Beam Computed Tomography Scans

<div><p>Abstract Imaging exams have important role in diagnosis of cemento-osseous dysplasia (COD). Cone beam computed tomography (CBCT) stands out for allowing three-dimensional image evaluation. This study aimed to assess the prevalence of cases diagnosed as COD on CBCT scans, as well identify the main imaging features related to these lesions. An analysis was performed in a database containing 22,400 radiological reports, in which all cases showing some type of COD were initially selected. These CBCT exams were reevaluated to confirm the radiographic diagnosis and determine the prevalence and distribution of the types of COD with regard to gender, age and preferred location, while describing its most common imaging aspects. Data were presented using descriptive analyses. There were 82 cases diagnosed as COD in the CBCT images (prevalence of 0.4%). The distribution of patients was 11 (13.4%) male and 71 (86.6%) female, with a mean age of 49.8 years (age-range 17-85 years). There were 47 (57.3%) cases of periapical COD, 23 (28%) of focal COD and 12 (14.6%) of florid COD. The mandible was more affected than the maxilla. In most cases, the lesions were mixed or hyperdense. All COD had well-defined limits and there were no cases of tooth displacement. In conclusion, periapical COD was the most common type and the most affected bone was the mandible. Imaging evaluation is critical for diagnosis and dentists should bear in mind all possible radiographic presentations of COD in order to prevent misleading diagnoses and consequently, inadequate treatments.</p></div
