    Human papillomavirus (HPV)-related head and neck squamous cell carcinoma (HNSCC) is considered to be a distinct clinical entity with better prognosis than the classical tobacco- and alcohol-associated tumors. The increasing incidence of this neoplasia during the last decades highlights the need to better understand the role of HPV in the development of these cancers. Although the proportion of HNSCC attributed to HPV varies considerably according to anatomical site, overall approximately 25% of all HNSCC are HPV-DNA positive, and HPV-16 is by far the most prevalent type. In this review we discuss the existing evidence for a causal association between HPV infection and HNSCC at diverse anatomical head and neck subsites

    Objetivou-se identificar a percepção de enfermeiros de um hospital universitário sobre o gerenciamento do pessoal de enfermagem com estabilidade no emprego. Pesquisa qualitativa desenvolvida em 2010 com dezesseis enfermeiros. Dados coletados por entrevistas semi-estruturadas e analisados pela Análise Temática geraram duas categorias empíricas: A segurança no trabalho versus a impunidade proporcionada pela estabilidade no emprego; e O (des)comprometimento no trabalho da enfermagem e a estabilidade no emprego. Verificou-se que estabilidade no emprego oferece segurança no trabalho; essa segurança produz impunidade, e os enfermeiros resistem em conduzir processos administrativos. Conclui-se que a segurança favorece a quebra de hierarquias, a impunidade gera a banalização das transgressões, pela falta de medidas administrativas ágeis para resolução de problemas; e a estabilidade no emprego não garante a qualidade da assistência
