ABSTRACT
INTRODUCTION: Soft tissue sarcomas (STSs) are rare tumors and constitute only 1% of all tumors in adults. Indeed, due to their rarity, most cases in Brazil are not treated according to primary international guidelines. METHODS: This consensus addresses the treatment of STSs in the extremities. It was made by workgroups from Brazilian Societies of Surgical Oncology, Orthopaedics, Clinical Oncology, Pathology, Radiology and Diagnostic Imaging, and Radiation Oncology. The workgroups based their arguments on the best level of evidence in the literature and recommendations were made according to diagnosis, staging, and treatment of STSs. A meeting was held with all the invited experts and the topics were presented individually with the definition of the degree of recommendation, based on the levels of evidence in the literature. RESULTS: Risk factors and epidemiology were described as well as the pathological aspects and imaging. All recommendations are described with the degree of recommendation and levels of evidence. CONCLUSION: Recommendations based on the best literature regional aspects were made to guide professionals who treat STS. Separate consensus on specific treatments for retroperitoneal, visceral, trunk, head and neck sarcomas, and gastrointestinal stromal tumor, are not contemplated into this consensus.

A pesquisa do nistagmo de posicionamento com óculos de Frenzel foi conduzida em 340 pacientes com hipótese diagnóstica de Vertigem Posicional Paroxística Benigna (VPPB). Houve comprometimento, em ordem decrescente de prevalência, dos canais semicirculares posteriores em 285 casos, posteriores ou anterioresem 44 casos, anteriores de canal semicircular posterior é comum, enquanto que o canal anterior é pouico freqüente e o de canal lateral é mais raro; o envolvimento labiríntico unilateral é mais freqüente do que o bilateral; o substrato fisiopatológico presumido de ductolitíase é mais comum do que o de cupulolitíase.
