Surgical procedures involving the rehabilitation of the maxillofacial region frequently require bone grafts; the aim of this research was to evaluate the interface between recipient and graft with cortical or cancellous contact. 6 adult beagle dogs with 15 kg weight were included in the study. Under general anesthesia, an 8 mm diameter block was obtained from parietal bone of each animal and was put on the frontal bone with a 12 mm 1.5 screws. Was used the lag screw technique from better contact between the recipient and graft. 3-week and 6-week euthanized period were chosen for histometric evaluation. Hematoxylin-eosin was used in a histologic routine technique and histomorphometry was realized with IMAGEJ software. T test was used for data analyses with p<0.05 for statistical significance. The result show some differences in descriptive histology but non statistical differences in the interface between cortical or cancellous bone at 3 or 6 week; as natural, after 6 week of surgery, bone integration was better and statistically superior to 3-week analyses. We conclude that integration of cortical or cancellous bone can be usefully without differences. HubMed – rehab

Methadone maintenance treatment (MMT) has been scaled up by the Chinese government alongside persistent compulsory drug user detention, but the extent to which detention interferes with MMT is unknown. The study systematically reviews Chinese MMT retention rates, reasons for drop out, and behavioural changes.Chinese and English databases of literature are searched for studies reporting retention rates, drug use and sexual behaviours among MMT participants in China between 2004 and 2013. The estimates are summarized through a systematic review and meta-analysis.A total of 74 studies representing 43,263 individuals are included in this analysis. About a third of MMT participants drop out during the first three months of treatment (retention rate 69.0% (95% CI 57.7-78.4%)). Police arrest and detention in compulsory rehabilitation was the most common cause of drop out, accounting for 22.2% of all those not retained. Among retained participants, changing unsafe drug use behaviours was more effective than changing unsafe sexual behaviours. At 12 months following MMT initiation, 24.6% (15.7-33.5%) of MMT participants had a positive urine test, 9.3% (4.7-17.8%) injected drugs and only 1.1% (0.4-3.0%) sold sex for drugs. These correspond to 0.002 (<0.001-0.011), 0.045 (0.004-0.114) and 0.209 (0.076-0.580) times lower odds than baseline. However, MMT participants did not have substantial changes in condom use rates.MMT is effective in drug users in China but participant retention is poor, substantially related to compulsory detention. Reforming the compulsory drug user detention system may improve MMT retention and effectiveness. HubMed – rehab

Cardiac syndrome X is a relatively common disorder, and still not much is known about the causative factors or its pathophysiology, which makes it difficult to cure. Due to its chronic nature and debilitating symptoms, many patients have significantly reduced quality of life (QOL).The purpose of this study was to assess the impact of phase III cardiac rehabilitation (CR) and relaxation on the QOL of patients.This research is a randomized clinical trial study. Forty eligible and consenting women (age 30-65 years) were randomly assigned to four groups. In the first group (n = 11), progressive muscle relaxation (PMR); in the second group (n = 11), phase III CR; and in the third group (n = 11), PMR along with phase III CR were performed for 8 weeks at home. The fourth group (n = 7) was used as the control group. Short form of QOL questionnaire (SF-36) was used for data gathering. Data analysis was performed using ?(2), Kruskal-Wallis, and rank sum difference tests.After phase III CR, relaxation, and combination of CR and relaxation, patients demonstrated improved QOL (P < 0.001). The results of post-test multiple comparisons showed that there were statistically significant differences between control and all intervention groups (P < 0.05). There was also statistically significant difference between relaxation and combination of phase III CR and relaxation groups (P < 0.5).An 8-week phase III CR program together with relaxation improved QOL of patients with cardiac syndrome X. We suggest phase III CR program together with relaxation as an effective treatment in these patients. HubMed – rehab
