Abstract
Persistent air leaks occur after Spontaneous pneumothorax both primary and secondary, and after lungs trauma and lung surgeries are sever problems encountered chest surgeons with. Persistent air leak causes longer patients hospitalization.
Materials and Methods: We used autologous blood pleurodesis in patients with persistent air leak for 30patients with more than 8 days air leaks, during a three years period 1377-1380 (1999-2002).
Results: The patients had 19 years up to 70 years old. Eight patients had thoracotomy and lobectomy and /or segmentectomies 6 with primary pneumothorax, 10 with secondary pneumothorax, and four with penetrated or blunt thoracic traumas. Blood was obtained from femoral or brachial veins and 70-150 mis. Injected in chest tubes. Chest bottle was first lied 80cm higher than body levels. After 24 hours repositioned in normal levels, and patients were supervised. Via chest tube we injected blood 70-100ml.for young patients, and 100-150 ml for older patients into intra pleural space. There were no clamped chest tubes. There were no pain, respiratory distress, fever, or cough in pleurodesized patients. The only patient's complaint was local pain in femoral vein or brachial vein because blood sampling and blood obtaining, although there was no local visible complication as hematoma or bleeding. After 48 hours in 24 patients air leak ceased. In six patients because persistent air leak autologous blood pleurodesis repeated, two patients after 48hours
air leak ceased, remaining four patients underwent for thoracotomies, success rate
was 86.6%.
Conclusion: According above success rate we suggest autologous blood pleurodesis in patients with persistent air leak is a reliable, effective, and no complicated procedure for persistent air leaks.

Abstract
Preoperative autologous blood donation is commonly used to reduce exposure to homologous blood transfusions among patients undergoing elective cardiac surgery. The aim of this study was to evaluate the effect of autologous transfusion on patients' hematocryte value, intra and postoperative blood loss, hospitalization time, the development of infective complications and other factors.
Materials and Methods: Between June 2001 to April 2002, 208 patients were underwent cardiac surgery in cardiac surgery ward in Imam Khomeini Medical Center. One or more blood units donate from 104 Patients before cardiopulmonary bypass and heparin injection, and transfused to them after CPB and Protamin injection (autologous Group, group 1). 104 patients underwent cardiac surgery routinely (control group, group 2).
Results: Mean of age was 55.9±8.6 in group 1 and 56.6±9.3 in group 2 (P=NS). 73 male and 31 females were in group 1 and 79 males and 25 females were in group 2 (P=NS). Smoking, familial history, hyperlipidemia, diabetes mellitus, renal failure, hypertension, stroke, and history of myocardial infarction was similar in two groups.
Severity of angina, urgency operation, number vessels disease, duration of cardiopulmonary bypass, duration of aortic cross clamp time, use of internal thoracic artery graft, and number of grafts was similar in both groups. Mean of bleeding post operation was 548 cc in group 1 and 803 cc in-group 2 (P=0.003). Bleeding that need to operation was 1.8% in group 1 and 8.6% in group 2 (P=0.002). Wound infection, mediastinitis, renal failure, ventilatory prolonged, stroke, need to Intra-aortic Balloon Pump (IABP), intraoperative bleeding, and hospital stay was similar in both groups. Mean of extubationt time was 10.2 hours in group 1 and 14.8 hours in group 2 (P=0.001).
Conclusion: Preoperative and intra-operative donations are safe and continue to contribute uniquely to blood conservation, providing important options in comprehensive blood conservation programs in current pediatric open-heart surgery.

Abstract
Background: The goal of this study was to evaluate, functional capacity of the knee in flexion and internal rotation after hamstring ligament harvest for Anterior Cruciate Ligament (ACL) reconstruction.
Methods: Fifty patients (male and 18-45 years old) with isolated ACL injury, randomly allocated in two equal groups (in one group, ACL reconstruction was performed with Tibialis Posterior allograft and in another group with quadruple hamstring ligament auto graft) and before and 6 months after surgery in both groups isokinetic flexion strength and isometric internal rotation strength of knee evaluated with Biodex System 4 dynamometer and rotational torque recorder, in order. Isokinetic flexion strength evaluated in sitting and prone position the later position was performed for deep flexion strength evaluation. Also subjective and objective assessment of all patients pre operatively and 6 months post operatively was documented with International Knee Documentation Committee (IKDC) questionnaire. In this study for first time, rotational torque strength of knee was recorded with new design measure, from isometric aspect and not isokinetic.
Results: Although significant improvements in IKDC scores, flexion and internal rotation capacity of the knee were observed in both groups, post operatively in respect to pre operatively there was no significant difference between 2 groups. (P<0.05 or more than 95% confidence Interval of the difference)
Conclusion: This study demonstrates that ACL reconstruction surgery, improves knee performance in flexion and internal rotation, regardless of hamstring tendon harvesting. Considering potential complications of allograft (for example: transfer of harmful diseases from donor to recipient), it is logical to use hamstring auto graft ligament for ACL reconstruction surgery. Because result of this study is not longstanding follow up and limited to male sex, for more worthfull conclusion, we suggest future study in both sex and with long duration of follow up.

Abstract
Background: Cartilage grafting is used in rhinoplasty and reconstructive surgeries. Autologous rib and nasal septum cartilage (auto graft) is the preferred source of graft material in rhinoplasty, however, homologous cartilage (allograft) has been extensively used to correct the nasal framework in nasal deformities. Autologous cartilage graft usage is restricted with complication of operation and limiting availability of tissue for extensive deformities. Alternatively, preserved costal cartilage allograft represents a readily available and easily contoured material. The current study was a formal systematic review of complications associated with autologous versus homologous cartilage grafting in rhinoplasty patients.
Methods: In this cohort retrospective study, a total of 124 patients undergone primary or revision rhinoplasty using homologous or autologus grafts with postoperative follow-up ranging from 6 to 60 months were studied. The types of grafts and complications related to the grafts were evaluated. This included evaluation for warping, infection, resorption, mobility and fracture.
Results: The total complications related to the cartilage grafts were 7 cases, which included 1 warped in auto graft group, three cases of graft displacement (two in allograft group and one in auto graft group) and three fractures in allograft group. No infection and resorption was recorded. Complication rate (confidence interval 0.95) in autologous and homologous group were 1.25(0.4-3.88) and 2.08(0.78-5.55) in 1000 months follow up. There was no statistically significant difference between autologous and homologous group complications. Onset of complication in autologous and homologous group were 51.23(49.27-53.19) and 58.7(54.51-62.91) month respectively (P=0.81).
Conclusion: The allograft cartilage has the advantage of avoiding donor-site scar. Moreover, it provides the same benefits as autologous costal cartilage with comparable complication rate. Therefore, it can be a reliable alternative material for rhinoplasty surgeries. A longer follow-up may be necessary to confirm the structural stability of the allograft cartilage grafts.
