Aim and Objectives
The aim of this study was to evaluate changes in alveolar bone height by means of radiographic examination and Straumann implant survival rate following maxillary sinus lift augmentation using autogenous bone in combination with platelet rich plasma (PRP) versus venous blood (VB).Methods
Fifty patients requiring sinus lift augmentation procedure included in the study were divided into two groups (n = 25). During the procedure the sub antral sinus cavity was augmented using autogenous bone taken from mandibular ramus area and mixed with PRP in one group and autogenous bone mixed with VB in the other group. Orthopantomograms were taken preoperatively, immediate, at 6 months and 1 year postoperatively. Height of alveolar bone at the site of sinus augmentation was measured on the radiographs. One hundred and twenty-one Straumann dental implants were placed after healing period.Results
Age of the patients in the study groups ranged from 36 to 69 years. Differences in mean values of bone height measurements recorded in the PRP series revealed significant differences among the three subgroups (P = 0.001). Significant differences were noted between immediate postop and 6 month (P < 0.01), immediate postop and year (P < 0.01). In the VB series also significant differences were revealed among the three subgroups (P = 0.0280). Significant differences were noted between immediate postop and 6 month (P < 0.05). Comparison of results of subgroups of the two series at the three intervals revealed significant differences at ‘immediate postop’ values (P = 0.0002) and ‘sixmon’ values (P = 0.0435). Differences between ‘year’ values were not significant. Two implants were lost in PRP group.Conclusion
The results of this limited study reveals that both groups recorded a good increase in the alveolar bone height after sinus augmentation and showed no significant differences between these groups when compared to each other at 1 year postoperatively. When both sub groups compared with immediate postop to year, PRP group showed significant difference and blood group showed no significant difference. 相似文献8.

BACKGROUNDDirect-acting antiviral (DAA) therapy regimens are highly effective at eliminating hepatitis C virus (HCV) infection but rates of sustained virologic response (SVR) are lower in patients with decompensated cirrhosis or hepatocellular carcinoma. Since many of these patients will be referred for liver transplant, they will require retreatment after transplantation. Sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) is recommended by guidelines as the preferred regimen to treat HCV in DAA-experienced patients following liver transplant however there is limited data.CASE SUMMARYWe present the cases of six liver transplant recipients who had previous treatment failure with sofosbuvir-based DAA therapy prior to transplantation and who then received SOF/VEL/VOX after transplant.CONCLUSIONThis case series demonstrate the real-world efficacy and safety of SOF/VEL/VOX in the post liver transplant setting. Treatment was successful with all patients achieving SVR, it was well tolerated, and there were minimal drug-drug interactions with their immunosuppressants. 相似文献

BACKGROUND: Osteoblastic metastases are commonly induced by prostate cancer. A canine prostate carcinoma xenograft (Ace-1) was developed and used to evaluate neoplastic prostate cell growth, metastasis, and effects on bone formation in nude mice. METHODS: Characteristics of the Ace-1 cells were evaluated with histopathology, radiography, and bioluminescent imaging (BLI). Immunohistochemistry and quantitative RT-PCR were used to evaluate the expression of factors important in the development of osteoblastic metastases. RESULTS: The Ace-1 cells were invasive and induced bone formation and destruction. Radiographs demonstrated a mixed osteoblastic/osteolytic reaction. Lung and lymph node metastases occurred in 30% of mice. The tumor cells expressed parathyroid hormone-related protein (PTHrP-141 isoform), cathepsin K, keratins 8/18, and vimentin, but not keratins 5/14, and were androgen receptor negative. Intracardiac (IC) injections resulted in metastases in vertebrae and long bones. CONCLUSIONS: The Ace-1 xenograft is a useful model for investigating the pathogenesis of prostate cancer invasion and mixed osteoblastic/osteolytic bone metastases. 相似文献
