Introduction: Stress occurs more frequently in groups in which the degree of responsibility and decision-making power play notable roles in society, such as professors and health professionals.
Objectives: To measure and understand the stress of professors in the undergraduate course of Medicine and Dentistry of a private educational institution in northeastern Brazil.
Methods: Observational, descriptive and exploratory study with a quantitative approach was conducted between November 2018 and September 2019.
Adenomatoid odontogenic tumor: Features of ameloblastic-like epithelial cells differentiation, secretion, and the nature of tumor cells products.

Background: This study aimed to investigate the differentiation of ameloblastic-like cells and the nature of the secreted eosinophilic materials in adenomatoid odontogenic tumors.
Methods: We studied histological and immunohistochemical characteristics of 20 cases using: cytokeratins 14 and 19, amelogenin, collagen I, laminin, vimentin, and CD34.
Results: Rosette cells differentiated into ameloblastic-like cells positioned face-to-face, displaying collagen I-positive material between them.
Article Synopsis
- Oral melanoma in HIV-positive patients is extremely rare, with only four total cases—including two new ones reported in this study involving 35- and 27-year-old women.
- Both patients exhibited significant health issues like low platelet counts, anemia, reduced CD4 cell counts, and high HIV loads.
- The tumors showed diverse cell types and were diagnosed using specific markers, but sadly, both patients had poor outcomes and died a few months after diagnosis, highlighting the need for careful differentiation from more common conditions like Kaposi's sarcoma in similar patients.
