Abstract
Background: Thyroid cancer is a rare disease which includes less than 1%
percent of all human cancers. The aim of this study is to evaluate the
demographic characteristics and risk factors among patients with thyroid
malignancy at the Cancer institute and Imam Khomeini hospital in Tehran
Iran.
Methods: This is a retrospective descriptive study of the charts of 320
patients admitted with the diagnosis of thyroid malignancy based on
pathologic reports in the above- mentioned hospitals from 1992 to 2002.
Results: From the 320 patients diagnosed with thyroid malignancy 68.1%
were papillary cancer, 10.9% were follicular cancer, 10.6% were anaplastic
cancer, 9.06% were medullary cancer and 1.2% were lymphoma.
The average of the patients was 50.2 years, ranging from 12 to 98 years
60.6% were female and 39.4 %were male 22.8% of the patients had
histories of thyroid nodule and 5% had received radiation therapy.
From the anatomic point of view 57.5% of the cancers were in the right lobe
of thyroid, 38.1% were in left lobe and 4.4% in the isthmus. None of the
patients had positive family history of thyroid malignancy.
Conclusion:
Thyroid malignancy is more prevalent in the fifth decade of life and more
common among females. Therefore, among patients in this group, alarming
symptoms, such as anterior neck mass, thyroid nodule and voice change,
should be evaluated more seriously.

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: Invasive procedures such as bone marrow aspiration in children with oncologic malignancies are painful and may produce anxiety for both patients and their parents. Various pharmacologic treatments have been used to sedate children undergoing bone marrow aspiration. This prospective randomized study was designed to compare the effectiveness of these combinations, as well as their associated hemodynamic and respiratory side-effects and recovery in pediatric patients undergoing bone marrow aspiration.
Methods: Fifty children with oncologic malignancies whose ages ranged between 2-12 years were enrolled in this study. Patients were randomly assigned either to the Propofol- Alfentanyl group or the Midazolam- Ketamine group for analgesia and sedation during bone marrow aspiration in the operating room. Time to induce sedation, sedation score and recovery time were recorded.
Results: There were no statistical differences between groups in weight, age, sex and duration of procedures. Procedures were completed with satisfactory sedation levels in all patients in the study groups according to the modified Ramsay score. Induction and recovery times in the Propofol- Alfentanyl group were significantly shorter than in the Midazolam- Ketamine group (p<0.001). After Midazolam- Ketamine sedation, a statistically significant increase in systolic blood pressure and heart rate were seen, however the opposite was observed after Propofol- Alfentanyl sedation. Other side effects, such as nausea and vomiting, agitation myoclonus and aspiration, were not seen in our patients.
Conclusion: Both Propofol- Alfentanyl and Midazalam-Ketamine combinations can be used safely and effectively for sedation and analgesia during bone marrow aspiration in the pediatric patient group.

Abstract
Background: Coarctation of aorta is narrowing of proximal descending aorta. Interventional procedures such as balloon angioplasty & stent implantation has been progressively in use as alternatives for surgery in increasing number of children with diagnosis of coarctation of aorta. The aim of this study was to evaluate the use of endovascular stent in children with coarctation of aorta.
Methods: We evaluated effectiveness and safety of stenting in all patients younger than 18 years old with coarctation and re-coarctation of aorta which treated by stenting between years 2004-9 at rajaei - heart centre in Tehran, Iran.
Results: we studied 53 patients younger than 18 years old with a follow up of six months. Totally 54 stents were implanted. Mean (±SD) age of the patients was 11.6±4.2yrs. Seventeen cases (32%) were younger than 10 years old, and 36 cases (68%) were 10 years and older. Mean (±SD) weight was 39.24±18kg. 16 cases weighting less than 25kg. Peak systolic pressure gradient (SPG) decreased from 46.26±17.07 to 1.03±0.19mmHg after procedure (p<0.001). There was no significant difference (p<0.001) in the gradient before and after stenting in the patients with native coarctation (Vs re-coarctation cases), less than 25 kg and under 10 years old groups. Complications developed in 44% of cases while dominantly were minor except in two cases re-dilatation of stent was not needed during six month of follow-up of the patients.
Conclusions: Stenting of coarctation of aorta can decrease complications and can be used safely in children weighing bellow 25kg and in children below 10yrs old.

Abstract
Background: Pulmonary valve stenosis (PS) is one of the most common congenital heart disease in children. Isolated pulmonary stenosis is the most common form of pulmonary stenosis. Isolated Pulmonary stenosis is responsible for 8 to 10 percent of congenital heart disease. Balloon valvuloplasty is the choice of treatment for this cardiac disease. One of the most important complications of this disease is pulmonary regurgitation in follow-up. The purpose of this study was to characterize the status of pulmonary regurgitation on follow-up after pulmonary valvuloplasty by balloon. Methods: We studied pulmonary regurgitation after balloon valvuloplasty retrospectively in children less than 14 years old age and isolated pulmonary stenosis. These patients had not complex congenital heart disease and admitted for balloon valvuloplasty during period of September 2001 to September 2011 in Shahid Rajaee Cardiovascular
Research Center. The mean time of follow-up was 7±2.5 years.
Results: Four hundred and fifty-eight patients with mean age of 10.3±8.6 months were studied. Two hundred and fifty-five patients were male and 230 were female. Right ventricular pressure was decreased from 82.3±42.2 mmHg before procedure to 45.2±22.4 mmHg after procedure (P= 0.043). Pressure gradient between right ventricle and pulmonary artery was decreased from 75.4±18.2 mmHg to 25.7±15.13 mmHg during procedure (P= 0.032). The day after procedure, 180 (37.1%) patients had no pulmonary regurgitation echocardiographic evaluation, 175 (36.08%) had mild, and 118
(24.3%) had moderate pulmonary regurgitation. In patients with moderate pulmonary regurgitation, 7 (0.14%) of those improve to severe pulmonary regurgitation. In echocardiographic exam, 12 (2.4%) patients had severe regurgitation the day after balloon valvuloplasty. During long-term follow-up (7±2.5 years) for 3 patient pulmonary valve replacement were performed. In our study, balloon to annulus ratio in three groups of pulmonary regurgitation (mild, moderate and sever) had significant correlation (P=0.012).
Conclusion: Pulmonary regurgitation was seen after balloon valvuloplasty in some patients.In most patients it had no symptoms and long-term follow-up is necessary

Abstract
Background: A major problem in surgical procedures is postoperative pain. The effectiveness of prescribing preoperative tizanidine in reducing postoperative pain is not clear. The aim of this study was to determine the efficacy of tizanidine as a premedication in reducing pain after septoplasty.
Methods: This double blind clinical trial study was performed in 71 patients aged from 18 to 50 years, undergoing septoplastic surgery for the first time, who were classified in ASA (American Society of Anesthesiologists) classes 1 and 2 in the Ear, Nose, and Throat (ENT) Department of Shafa Hospital, in Kerman, Iran from April 2014 to March 2015. Patients were randomly assigned into two groups using numbers from a randomization table. A dosage of 4 mg of tizanidine was administered orally to the patients two hours before the surgery (septoplasty) in the intervention group. In the control group, placebo pills which were 100 mg vitamin B1 were prescribed. The severity of pain was measured and recorded after 4 and 8 hours, and the morning after the surgery.
Results: 62 patients (87.32%) were male and 9 (12.68%) were female. The mean age of the subjects was 24.6±7.5 years. The two groups were similar in regard to age (P=0.54), but the duration of surgery was different in the two groups (P=0.038) and was longer in the group that received tizanidine. The mean of pain was different between the two groups, after 4 hours and was significantly higher in the group that received tizanidine (P=0.043). The mean of pain was not significantly different between the two groups after 8 hours (P=0.95) or one day after surgery (P=0.79).
Conclusion: Although some researchers have reported that taking tizanidine before some surgeries may reduce postoperative pain, in this study the administration of tizanidine before surgery was not effective in reducing pain after septoplasty.
