Abstract
Between 1990-97 two hundered children referred to our department with end-stage renal disease (ESRD) for renal replacement therapy. The ages of these children were 1-14 years (mean 8.14). There was no significant difference in incidence of ESRD between two sexes. We evaluated these children for the causes of ESRD. The most common causes were: Pylonephritis and congenital anomalies of urinary tract (35.5%), glomerular diseases (22.5%) and hereditary kidney diseases (13.5%).

Abstract
Valvular and coronary artery disease are among the most important causes of disability and death in the world and Iran as well. Every year, half a million death because of these diseases is reported in United State. The incidence of degenerative and valvular diseases of heart is increasing. Considering the industrialization of our country, the incidence of these kind of problems are increasing as well. In this study, there is an attempt to recognize the causes of cardiac surgery. We conducted a retrospective study in 915 cardiac surgery patients (630 CABG and 285 valve replacement) from 1374 to 1377. In CABG patients, there were 46 cases of reoperation (78.3 percent male 21.7 percent female). The most reoperations for bleeding was less than 24 hours in 90.3 percent. In valvular patients the causes of reoperation were: A) Valvular complications (female/male=3/1), B) Non valvular complications (female/male=1/3). The most common nonvalvular complication was bleeding (66.6 percent). The most common valvular complication was bioprosthetic valve degeneration. The meantime between two operation in valvular complications was 11.8 years. In all cases (915) the incidence of bleeding was 3.8 percent, mediastinitis 0.8 percent, cardiac tamponade 0.8 percent and GI bleeding 0.5 percent.

Abstract
Background: Tetralogy of Fallot is the most common cyanotic congenital heart disease. The systolic and diastolic function in both ventricles is altered even after successful corrective surgery for this defect with a transannular patch. Pulmonary regurgitation, a common complication after this treatment, is usually well tolerated in childhood. The aim of this study was to assess the combined diastolic and systolic function of both ventricles using the Doppler-derived myocardial performance index (Tei index) in patients who underwent surgical repair of tetralogy of Fallot using a transannular patch. In this article we discuss the impact of pulmonary regurgitation on right ventricular function and clinical outcome, the role of echocardiographic imaging, and current management strategies for patients with pulmonary regurgitation after this treatment.
Methods: Sixty eight patients with tetralogy Fallot were studied in Shahid Rajaie referral Cardiovascular Center during 2003-2005. The studied population, 36 male and 32 female with a mean age of 7.5±4 years and a history of corrective surgery for tetralogy of Fallot using a transannular patch. These patients were randomly selected and assessed by Doppler echocardiography.
Results: Fifty-seven patients (84%) had mild to moderate pulmonary regurgitation, whereas 11 patients (16%) had severe pulmonary regurgitation. Right ventricular Tei index was significantly increased in patients with severe pulmonary regurgitation compared those with mild to moderate pulmonary regurgitation (0.54±0.18 vs 0.24±0.11, P<0.01). Left ventricular Tei index was increased in patients with severe pulmonary regurgitation compared those with mild to moderate pulmonary regurgitation (0.46±0.22 vs 0.32±0.14, P<0.05).
Conclusions: The findings of this study suggest that pulmonary regurgitation is a serious complication after repair of tetralogy of Fallot with a transannular patch. Delaying surgery in such patients risks irreversible ventricular function.

Abstract
Background: The usage of pericardium of patient himself, for support of anastomosis lines may carry benefits in patients undergoing aortic valve replacement with pulmonary autograft (Ross). The aim of the present study was to compare the short term results of aortic valve replacement with pulmonary autograft with routine and offered methods.
Methods: In a non-randomized clinical trial, 64 patients who referred to cardiac surgery ward of Imam Khomeini hospital Tehran Iran from December 2002 to December 2006 for aortic valve replacement with pulmonary autograft with two different methods. In the first two years of this study all of the patients were operated with routine procedure (group A, n=28) and during the next two years, all of them were operated with authors' offered method in which the patient`s pericardium was used for support of anastomosis lines (group B, n=36). Some of clinical parameters and outcome were compared between two groups.
Results: There were no significant differences between mean of age, sex, pathology, preoperative and postoperative EF in two groups. In group B, the mean pump time was significantly lower than group A (144.09±26 vs. 179.64±25 min). The mean Cross-clamp time was significantly lower in group B (118.5±22 vs. 136.93±19 min) Need for blood transfusion in ICU was significantly lower in group B (35.71% vs. 68.57%). Mean ICU Stay and Postoperative Hospital Stay were significantly lower in group B (1.3±0.3 vs. 1.9±0.7 and 5.2±0.9 vs. 5.9±1.5 days respectively). Overall mortality was four death (6.25%) which was not significant between two groups.
Conclusions: The usage of patient's pericardium for support of anastomosis lines in patients undergoing aortic root replacement with pulmonary autograft carry advantages to routine procedure and its utilization is advocated in other centers.

Abstract
Background: Dabigatran etexilate is one of the few direct thrombin inhibitors with anti-coagulant activities and the following distinctive features: taken orally, no need to closely monitor for complications, and no need for regular dose adjustments. Relying on the above mentioned valuable advantages, dabigatran etexilate can be considered as a premier choice for the prevention of venous thromboembolism after knee replacement arthroplasty.
Methods: Forty five patients undergoing 50 knee replacement surgeries were included in this case-series study undertaken in Hazrat Rasool Akram and Khatam-alanbia Hospitals during 2010. Dabigatran etexilate was administered for the prevention of venous thromboembolism after knee arthroplasty in doses of 110 mg in the first 1-4 h after surgery followed by daily doses of 220 mg for 10 days. Patients were examined 3 times and a color Doppler sonography was performed on the 11th day to check for venous thrombosis. Finally, the patients were re-examined at the end of the 1st and the 3rd months postoperatively.
Results: Only one out of 45 patients was diagnosed to have venous thrombosis on sonography done on the 11th day but the patient did not have any symptoms and repeat sonographies at the end of the 1st and the 3rd months postoperatively showed no venous thrombosis either. No complications were witnessed in the patients in the 3-month follow-up period.
Conclusion: Dabigatran etexilate (220 mg/d for 10 days) can be an effective drug against venous thrombosis after total knee replacement surgeries.

Abstract
Background: The patient's position during the recovery time after arthroplasty surgery can be a factor in reducing complications and improving patients’ condition. Therefore, this study was performed to compare the knee range of motion after soft tissue repair in both flexion and extension positions of total knee arthroplasty.
Methods: This study is a double-blind clinical trial. The study population was all candidates for total knee arthroplasty surgery in Al-Zahra and Kashani hospitals in Isfahan from July 2011 to September 2012. The sample size was selected using the statistical formula of 88 patients and randomly divided into two groups of flexion and extension. In the first group during the knee soft tissue repair, the knee was in flexion and in the second group it was in extension and then it was repaired. Information such as age, sex, body mass index and surgical position were recorded in the checklist. The knee range of motion was measured at the end of the first, second, fourth, eighth and twelfth weeks and recorded in a checklist. In order to compare the pattern of changes in mean knee range of motion over time in the two groups, mixed linear models and conventional marginal models to generalized estimator equations were used by STATA software.
|
Results: The results showed that there was no significant difference between the flexion and extension groups in knee range of motion. In both groups, the mean knee range of motion increased with time (P<0.001). The mean scores of knee function after the end of the twelfth week in the flexion and extension groups were 141.04±23.19 and 143.09±22.34, respectively, and this difference was not significant.
Conclusion: Soft tissue repair in a particular position is not so effective on the outcome that we want to institutionalize it by spending a considerable amount of budget for training surgeons.
