ABSTRACT
OBJECTIVE: To analyze the effect of a Pulmonary Rehabilitation Program (PRP) on the levels of anxiety and depression and the quality of life of patients with chronic obstructive pulmonary disease. METHOD: Patients with chronic obstructive pulmonary disease (COPD) who completed the PRP of 3 weekly sessions of 60 min duration for 12 weeks, a total of 36 sessions, were assessed using Beck Inventory (BAI and BDI) and Saint George's Respiratory Questionnaire (SGRQ). RESULTS: A total of 125 individuals, with an average age of 63.7 ± 8.8 years, FEV1: 1.17 ± 0.57L (43.18 ± 18.79% predicted), 61.6% male and 38.4% female, were analyzed. The BAI and BDI before and after PRP were, respectively, 10.15 ± 6.32 vs. 7.67 ± 7.21; p=0.0041 and 12.60 ± 7.99 vs. 8.96 ± 7.29; p=0.00016. The results of the SGRQ domains were, respectively, Before and After symptoms (48.53 ± 20.41 vs. 32.58 ± 18.95), Activity (69.15 ± 20.79 vs. 52.42 ± 23.70), Impact (32.92 ± 18.29 vs. 20.27 ± 16.70), Total (46.69 ± 16.90 vs. 32.07 ± 16.96). When correlating the BDI to the domains of the SGRQ, weak correlations were observed (Symptoms r=0.22; p=0.01; Activity r=0.28; p=0.001; Impact r=0.52; p=2.72; Total r=0.44; p=0.17). In the same way, weak correlations were observed when correlating the BAI to the SGRQ (Symptoms r=0.28; p=0.0009; Activity r=0.32; p=0.0005; Impact r=0.42; p=7.33; Total r=0.43; p=0.74). CONCLUSION: Although the PRP improves levels of depression and anxiety as well as the quality of life in patients with COPD, no significant correlation of these analyzed variables was observed.

A 47-year-old man with a six-month history of progressive tetraparesis and sphincter disturbances developed tetraplegy after two years and died. A cervical MRI revealed an ill-defined, enhancing lesion from C1 to C6, internally attached to the dura mater and compressing the spinal cord. At necropsy, eight whitish nodes and diffuse thickening of the dura mater from C1 to C6 were found. Histological studies revealed multiple en plaque lymphoplasmacyte-rich meningiomas. The radiologic and pathologic aspects of lymphoplasmacyte-rich meningioma are reviewed and the atypical features of this case, such as macroscopic appearance and the histological variant, are described.

The purpose of this study was to compare the effectiveness of plaque control performed with electric and manual toothbrushes. Fifteen children with primary dentition and 14 children with mixed dentition were divided in two groups and randomly assigned to utilize a manual or an electric toothbrush. In the first session, professional plaque removal was performed, and the children spent 24 hours without brushing their teeth. In the second session, plaque was disclosed and assessed on all facial and lingual surfaces. After that, all children brushed their teeth with the predetermined toothbrush. The next procedure was the disclosure and measurement of residual plaque. After a period of 7 days, the children switched the kind of toothbrush, and the same procedures were repeated. According to the statistical analysis of the results, there were no significant differences concerning plaque removal when the toothbrushes were utilized by children with mixed dentition. On the other hand, the electric toothbrush promoted significantly greater plaque removal on the lingual surfaces of teeth from children with primary dentition.

Myelin phagocytosis during Wallerian degeneration and immune-mediated demyelination depends on the action of mononuclear cells of the monocyte/macrophage system. The present study investigated the role of the macrophage scavenger receptor, a trimeric membrane glycoprotein, in myelin uptake by macrophages. Two in vitro models of myelin phagocytosis were used: an organ culture model of mouse peripheral nerves exposed to cocultured macrophages and a quantitative flow cytometric assay. Different concentrations of the monoclonal rat anti-mouse scavenger receptor antibody (2F8) were applied to these systems to selectively block the macrophage scavenger receptor. Concentration-dependent effects on macrophage migration and myelin uptake were seen when the macrophage scavenger receptor was blocked by the antibody 2F8. Low concentrations reduced myelin phagocytosis by the invading macrophages; higher concentrations completely abolished macrophage invasion of the nerves. Using a quantitative flow cytometric assay it was also shown that the 2F8 antibody inhibits phagocytosis of myelin in a dose-dependent manner. These data indicate that the macrophage scavenger receptor is involved in myelin phagocytosis by macrophages.
