RESUMO
OBJECTIVES: To critically analyse and discuss oral hygiene protocols in the hospital environment in patients admitted to the ICU, through a systematic review of the literature. METHODS: The electronic search was performed on Pubmed, Cochrane, Web of Science and Google Scholar databases. The indexing keywords according to the PRISMA protocol were: 'hospital dentistry', 'oral health', 'oral care' and 'intensive care unit'. RESULTS: The initial search resulted in a total of 2671 articles. Pre-selection based on titles led to the exclusion of 2510 articles and the remaining 36 were selected for abstract reading. After analysing the eligibility of the articles, eight studies were included in the review and submitted to qualitative analysis. CONCLUSION: It can be concluded that cleaning with a soft bristle brush, use of chlorhexidine and lip moisturizing are methods commonly used in dental care actions in patients hospitalized in intensive care units.
RESUMO
Syphilis can mimic, clinically and microscopically, many other diseases. By microscopy, typically syphilis presents with plasma cell infiltration, admixed with lymphocytes and macrophages, in lichenoid and/or perivascular/perineural distribution pattern. When exuberant, this inflammatory infiltrate can mimic a lymphoproliferative disorder (LPD), notably plasma cell neoplasia or lymphoma. To date, about 12 cases of secondary syphilis, all but one in extraoral location, suggesting initially a LPD, have been published. Here, to our knowledge, we report an unusual case of intraoral primary syphilis initially suggesting LPD, notably lymphoid hyperplasia (pseudolymphoma); however, mucosa-associated lymphoid tissue (MALT) lymphoma and follicular lymphoma could not be disregarded. Polyclonality of plasma cells on immunohistochemistry, in strict clinical correlation, was essential to arrive at the correct diagnosis.
