This is the first report on the presence of flower cells in HTLV-1-infected children and adolescents. Furthermore, these cells have not previously been reported in IDH patients. The cases with flower cells probably represent precursory ATL cases, these patients being at a greater risk of developing ATL.
Subcutaneous panniculitis-like T-cell lymphomas (SPTLs) α/β are rare in childhood. The present report refers to a case of a 7-year-old male child presenting an extensive skin lesion that began when he was 5 years of age. Two biopsies were evaluated using the CD3, CD4, CD8, CD56, βF1, and TIA markers. A dense infiltrate of CD3+, CD4−, CD8+, CD56−, βF1+, and TIA+ pleomorphic lymphocytes was found in the subcutis. The previous biopsy showed cytophagic histiocytic panniculitis with a small focus on CD8+ and βF1+ malignant cells. The lesion regressed spontaneously. This case shows that prognosis may be excellent in SPTL (α/β). On the other hand, it also serves as an alert that a biopsy performed in an area of cytophagic panniculitis may lead to misdiagnosis.
ResumoO presente estudo apresenta as especificidades da EaD que se constituem em desafios para que essa modalidade de ensino se institucionalize nas Instituições de Ensino Superior. Realizou-se um levantamento dos gestores acadêmicos associados aos cursos de graduação em oferta na UFRN, traçando um perfil destes por meio da identificação dos cargos que exercem, unidades de lotação e tempo de serviço. O presente estudo assume uma natureza qualitativa, por meio de pesquisa participante, considerando tratar-se de amostra não probabilística intencional. Os resultados apontam que o processo de institucionalização ainda se encontra num estágio embrionário, embora se reconheçam os esforços dos gestores acadêmicos em compreender a importância da modalidade a distância no momento atual, com a inserção das tecnologias de informação e comunicação. Palavras-chave: Educação a Distância. Ensino Superior. Institucionalização.
IntroduçãoA Educação a Distância (EaD) constitui, nos dias de hoje, uma realidade na qual as Instituições Federais de Ensino Superior estão inseridas. Com o desenvolvimento e aprimoramento de novas Tecnologias de Informação e Comunicação (TIC), é possível estabelecer uma interação efetiva entre os sujeitos do processo de educação formativa, além de promover a disseminação de informações e, consequentemente, a construção coletiva do aprendizado por meio da mediação tecnológica.
Diffuse large B-cell lymphoma represents approximately 30%–40% of all diagnoses of non-Hodgkin's Lymphoma and may represent up to 80% of all lymphomas that arise in the palatine tonsils. Several studies have attempted to correlate clinical, laboratorial, and tissue factors with the prognosis of the lymphomas, such as the International Prognostic Index, the tissue expression of some proteins, and the lymphocyte count at the time of diagnosis, as well as to correlate Epstein-Barr virus (EBV) infection with worse prognoses. Patients with palatine tonsil DLBCL, from Salvador, Bahia, Brazil, were studied in order to identify prognostic factors. Twenty-four patients with DLBCL were studied. The factors that negatively influenced the patients' survival rates were the lymphocyte count at the time of diagnosis <1.000/mm3 and the Bcl-2 protein expression. There was no CD5 expression in these lymphomas, and neither was there an association with EBV infection.
The objective of this article is to analyze the relationship between theoretical and practical knowledge in accounting training based on the political-pedagogical foundations of higher education in the state of Paraiba. For that, we turn to the contributions of Jürgen Habermas's theory of communicative action in order to understand how the relationship is established between theoretical discourse and practical discourse, drawing on definitions of "instrumental reason" and "communicative reason". To develop this empirical classification study, with a quantitative and qualitative approach, we employed the exploratory typology through bibliographic and documentary research. For data collection we applied a questionnaire with closed questions to students/interns of the public institutions analyzed. The results of the questionnaire show that the courses have an eminently theoretical format. Full-time practices are not applied and their focus is on the "modus operandi". We note that in accounting training, practice cannot be dissociated from theory and vice versa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
