METHODS From a 6-year prospective cohort study with 268 individuals under PMT, 124 individuals had complete periodontal clinical data recorded between T1 (baseline) and T2 (final data at the last PMT appointment). Individuals were divided into two groups, being 35 individuals with depressive disorders (DD) and 89 individuals without DD (NDD). Full-mouth periodontal examination was evaluated at T1 and T2. RESULTS The periodontal status of NDD was significantly better then DD at T2. In the NDD group, the recurrence of periodontitis was 50.6% whereas in the DD group was 62.8%. Moreover, the following variables were significantly associated with recurrence of periodontitis in final multivariate logistic regression model DD, age, co-habitation status without companion, smoking and the interaction between DD and smoking. CONCLUSION Individuals with DD undergoing PMT presented higher rates of recurrence of periodontitis and tooth loss when compared to individuals without DD. Additionally, the interaction between DD and smoking significantly increased the risk for the recurrence of periodontitis.

OBJECTIVE To determine different phenotypes of T regulatory cells during the maintenance phase chemotherapy for pediatric acute lymphoblastic leukemia (ALL). MATERIALS We evaluated the percentages of regulatory T cells by flow cytometry. Soluble CTLA-4 (sCTLA-4) in plasma was evaluated by ELISA assay. RESULTS Increased percentages of CD4+CD25+ T cells, CD4+CD39+ T cells, CD4+Foxp3+ T cells, and CD4+CD25High T cells were observed in children with ALL in comparison to healthy controls. In addition, th
