Tomographic findings of gastric gastrointestinal stromal tumor and correlation with the mitotic index.

Context: Gastrointestinal stromal tumors are uncommon abdominal neoplasms and can affect any portion of the gastrointestinal tract.

Objectives: Describe the tomographic findings of the gastrointestinal stromal tumor of gastric origin, correlating it with the mitotic index.

Methods: Twenty-one patients were selected within the period of January 2000 and 2008, with histopathological and immunohistochemical diagnosis of gastric gastrointestinal stromal tumors, who presented computed tomography done before the treatment.

[Comparative study between different radiographic plans in knee osteoarthritis].

Unlabelled: Perform a comparative analysis (with the criteria of Ahlbäck original classification) of the anteroposterior (AP) weight-bearing radiograph of knee in extension and of Rosenberg(2) view, in symptomatic arthritic knees. The analysis aims at revealing agreement or disagreement between (AP) view and Rosenberg view and the degree of articular degeneration and the advantages of these views.

Patients And Methods: From January 2005 to March 2007, a prospective study was conducted with 76 selected patients (111 arthritic knees) attending the outpatient clinic, at the knee unit, and subjected to the radiographs proposed in the present study.

Sentinel lymph node identification in breast cancer: a comparison study of deep versus superficial injection of radiopharmaceutical.

Objectives: Sentinel lymph node biopsy (SLNB) has been performed for purposes of disease staging. SLN is usually located in the axillary region and internal mammary chain (IMC). Metastasis in internal mammary nodes can be an important prognostic factor and an indication for systemic treatment in patients with small carcinomas.
