RESUMO
Abstract: The objective of this study is to present a tool to help understand how variables associated with oral cancer prevention relate to each other in a social network. A search of the Scopus database was performed using terms related to oral cancer and prevention from 2000 to 2020. The keywords were used as nodes and were analyzed using NodeXL, which produced the network graphic analysis. From the 1004 publications available, 4038 different keywords were obtained and then grouped into 75 constructs based on conceptual similarity. The most influential nodes were risk factors, comorbidities, epidemiology, and treatment. However, topics such as technology, telemedicine, self-examination, and diagnostic delay remain far removed from central relations. Network analysis enabled us to observe the bias of biological and basic science in the field and identify a need for studies concerning primary prevention, behavioral interventions, and inequalities in oral cancer.
RESUMO
Introduction: Kaposi sarcoma is a vascular neoplasm composed of endothelium-lined vascular spaces and spindle-shaped cells. It often manifests with multiple vascular nodules on the skin and other organs. Kaposi sarcoma is rare in HIV negative patients and it is associated with HHV-8 infection. There are four types: classic, endemic, iatrogenic and HIV-associated. Patients with HIV/AIDS are also at increased risk of developing Kaposi sarcoma. Objective: The aim of this article is to present two cases of Kaposi sarcoma in the hard palate of HIV/AIDS male patients. Case report and conclusion: Kaposi sarcoma should be considered in the differential diagnosis of any AIDS patient who presents with bluish, smooth, firm, nonpulsatile macule or nodule in the region of the hard palate. Development of Kaposi sarcoma in the oral cavity also has prognostic implications for untreated HIV patients, who are found to have higher death rates than patients affected only by cutaneous disease.
