RESUMO
Objective To investigate the risk factors for acute radiation esophagitis andpneumonitis after radiation therapy in esophageal cancer (EC) patients with diabetes or hypertension.Methods A total of 373 EC patients receiving three dimensional conformal radiation therapy (3D-CRT) or intensity modulated radiation therapy (IMRT) were included in this study.Among these patients,42 showed concurrent with diabetes and 99 with hypertension.Radiation esophagitis or pneumonitis in patients with or without diabetes,and with or without hypertension were monitored in the 1-year follow up,respectively.Results The prevalence of grade 1,2,3 and 4 radiation esophagitis in diabetes and non-diabetes patients was 40.5％,38.1％,14.3％,4.8％ and 66.2％,27.8％,2.7％,1.8％,respectively,while that of the grade 1,2 and 3 radiation pneumonitis in diabetes and non-diabetes patients was 31.0％,16.7％,9.5％ and 30.8％,15.7％,1.2％,respectively.The prevalence of grade 3 or above radiation esophagitis and pneumonitis in patients with diabetes and was significantly higher than those with non-diabetes (x2 =13.573,12.279,P ＜ 0.05).The prevalence of grade 1,2,3 and 4 radiation esophagitis in hypertension and non-hypertension patients was 49.5％,38.4％,8.1％,3.0％ and 68.2％,25.5％,2.6％,1.8％,respectively,while that of the grade 1,2 and 3 radiation pneumonitis in hypertension and non-hypertension patients were 30.3％,18.2％,5.1％ and 31.0％,15.0％,1.1％,respectively.The prevalence of grade 3 or above radiation esophagitis and pneumonitis in patients with hypertension was significantly higher than those with non-hypertension (x2 =5.695、5.422,P ＜ 0.05).Diabetes is an independent risk factor for grade 3 or above acute radiation esophagitis and pneumonitis.Conclusions Diabetes or hypertension might be risk factors for severe radiation esophagitis and pneumonitis in EC patients receiving radiation therapy.
RESUMO
Objective To evaluate the outcome of surgical treatment of tricuspid valve regurgitation after valve replacement.Methods Twenty one patients with tricuspid valve insufficiency after valve replacement were performed surgical treatment.Tricuspid valve-plasty was performed in 17 patients and tricuspid valve replacement was done in 4 patients.Three patients underwent edge-to-edge tricuspid valveplasty.DeVega procedure was performed in 5 patients.Cosgrove-Edward annuloplasty ring was used in 15 patients.Four patients' valve were replaced by SJM bileallet mechanical prostheses.Results There was 3 patients dead early after operation with a mortality of 14.3％(3/21).The causes of death including multiple organ failure,cardiac arrest and low cardiac output syndrome.The rate of early postoperative complications was 33.3％ (7/21),including pulmonary edema,arrhythmia,acute renal failure and low cardiac output syndrome.The patients were followed up 9-60 months.The rate of readmission was 23.8％ (5/21).Two patients went to hospital again for pleural effusion,1 patient for left ventricular dysfunction and 2 patients for right ventricular dysfunction.The other patients recovered well.Conclusions Surgical therapy is effective on severe tricuspid valve regurgitation after valve replacement.Preoperative aggressive treatment of heart failure,a reasonable grasp of surgical indications and timing of surgery,strict perioperative management are the keys to guarantee patients a smooth recovery.
