Abstract
Background: During general anesthesia in patients with mediastinal mass compression effect on the heart, great intra thoracic vessels, or tracheal tree can lead to decrease venous return, cardiovascular collapse or tracheal obstruction. These complications may be worsened after induction of general anesthesia or prescribing muscle relaxants.
Case report: A twenty one years old female with huge anterior mediastinal mass was a candidate for right sided thoracotomy. Compression effect on the adjacent structures has been reported in chest CT scan and in echocardiography. Awake oro-tracheal intubation was performed in sitting position. Then patient positioned to left lateral decubitus for thoracotomy During surgery asystole occured. We changed the position to remove compression effect on the heart and great vessels. Fortunately these maneuvers changed asystole to sinus rhythm.
Conclusion: Decreased thoracic muscular tone and removed spontaneous ventilation after muscle relaxant may threaten patient’s life. Change of patient’s position can remove the compression effect.

Abstract
Background: Entanglement of the umbilical cord around fetal neck has been reported to be associated with birth asphyxia. On the other hand, current evidence suggests that umbilical arterial pH analysis provides the most sensitive reflection of birth asphyxia. In this study we aimed to evaluate and compare the umbilical arterial hydrogen-ion concentration (pH) and to analyze the blood gases of neonates with or without nuchal cord.
Methods: In this cohort study, 92 newborns with and 95 without nuchal cords were enrolled at Shahid Akbar Abadi Hospital in Tehran, Iran between the years 2009 and 2010. From each newborn an umbilical arterial blood sample was collected to measure pH, base excess and blood gases.
Results: There were no statistically significant differences between newborns with or without nuchal cord regarding maternal age, gestational age, and history of pregnancy. The mean pH in the newborns with nuchal cord (7.21±0.1) was significantly less than the value in the newborns without the cord (7.28±0.1), (P<0.001). In contrast, the mean base excess in the newborns with nuchal cord was more than the ones without the cord (P<0.001). Seven newborns (7.9%) in the group with nuchal cord passed meconium during labor while only one (1%) newborn did so in the other group.
Conclusion: Our finding showed that nuchal cord had a significant relationship with acidosis in newborns with nuchal cord. However, this finding needs further investigation to reach a common conclusion.

Abstract
Background: The basal levels of androgens in women decline gradually with age. These changes may reduce muscle strength and bone density leading to fatigue and psychological problems. Thus, the aim of this study was to compare the effects of resistance and endurance exercises on androgens, cortisol and lactate concentrations in elderly women.
Methods: In this study, 10 elderly women with a mean age of 54.3±3.74 years and a BMI of 24.88±2.07 kg/m2 completed an endurance exercise session (ES), a resistance exercise session (RS), and a control session (CS) in a randomized, cross-balanced design. The RS consisted of three sets of 10 repetitions of eight exercises with 80% 1RM (one repetition maximum) over of 45 minutes and the ES consisted of cycling at 60%-70% of maximum oxygen consumption for 45 minutes. During the CS, subjects performed no exercise. Before and immediately after exercises, and after 15 minutes of recovery, and also during CS blood samples were obtained an analyzed for serum testosterone, dehydroepiandrosterone sulfate, cortisol and lactate.
Results: There was a significant increase in testosterone levels following resistance and endurance exercise sessions (P<0.05). Dehydroepiandrosterone sulfate demonstrated a significant increase after resistance exercise (P<0.05). While differences in cortisol levels were not significant within groups, but they were significant (P<0.05) between groups.
Conclusion: A session of resistance exercise in elderly women can increase concentrations of androgens that are essential for their health and well-being.

Abstract
Background: Scaphoid non::::union:::: remains a challenging problem for hand surgeons. In this study, we assessed the functional outcome of scaphoid non::::union:::: treatment and the influence of a number of variables on it.
Methods: In this study we recruited 24 patients with scaphiod non::::union:::: by consecutive sampling at Dr. Ali Shariati Teaching Hospital, in Tehran, Iran in 2008-2011. We examined the patients by antero-posterior (AP) and lateral view radiographies and wrist MRIs. Functional outcome of surgery was scaled according to Mayo wrist and Quick DASH scoring systems.
Results: Among 10 cases with osteonecrosis, there were 7 (70%) cases of radiological ::::union::::. In 13 (92%) out of 14 cases who had no signs of osteonecrosis, we radiologically confirmed scaphoid ::::union:::: after the treatment. The total ::::union:::: rate was estimated to be 83% at the end of 24 months follow up (P<0.05).
Conclusion: The results showed that patients with scaphoid non::::union:::: have improved function after surgical treatment.

Abstract
Background: Abacavir is an anti-retroviral medication used to treat HIV infected/AIDS patients and its efficacy has been proven in randomized clinical trials. The most significant adverse reaction associated with abacavir is the acute hypersensitivity phenomenon which manifests in many forms and in severe cases could result in death. Hypersensitivity reaction to abacavir has been closely linked to the presence of HLA-B*57:01 allele. Avoidance of abacavir initiation in allele-positive patients is the most effective strategy in preventing possible severe hypersensitivity reactions. Previous epidemiologic studies have made great strides toward delineating HLA-B*57:01 allele frequency in different regions of the World and the available results indicate significant discrepancy between geographical regions. Despite these efforts, no study to date has determined the allele frequency among Iranian HIV-positive patients. The aim of the present study was to determine the proportion of allele-positive patients among a group of Iranian HIV-infected patients.
Methods: Between September 2012 and February 2013, 122 HIV-positive patients were selected among patients referred to Imam Khomeini Hospital’s Consultation cen-ter for high risk behaviors using the convenience sampling method. Sampling scheme was designed in a manner to include equal number of infected patients with and without clinical Acquired Immunodeficiency Syndrome (AIDS). Patient data was collected using available records and a blood sample for DNA analysis was also obtained. Presence of HLA-B*57:01 allele was determined using the Polymerase Chain Reaction- Sequence Specific Method (PCR-SSP).
Results: Seventy three patients (59.8%) were male. Co-infection with hepatitis B and C was observed in 1.7% and 40.7% of the patients, respectively. History of addiction and anti-retroviral therapy was positive in 50.0% and 60.7% of the patients, respectively. Overall, three patients were allele-positive which corresponds to a frequency of 2.46% (95% CI: 0.005-7.30). No association between presence of allele and investigated vari-ables were identified.
Conclusion: Frequency of HLA-B*57:01 allele among a group of Iranian HIV-infected patients is estimated to be 2.5%. This rate is comparable to those reported in other Middle-Eastern countries, yet is relatively lower than reports generated from South-Eastern Asia, Europe, and the United States. Future studies with larger sample sizes are needed to corroborate these findings.

Abstract
Background: Wrist arthroscopy is an evolving diagnostic and therapeutic modality which is progressively used by Iranian surgeons. Little data is published about the procedure’s indications, outcomes, complications and prognostic factors. In following study we evaluate the outcome and complications of diagnostic and therapeutic arthroscopy in our patients.
Methods: In a prospective study from September 2009 to March 2013, 100 patients entered in the study. All the patients had chronic wrist pain without any sign of improvement despite at list three months non-operative treatment and underwent diagnostic and therapeutic wrist arthroscopy. All patients were evaluated by wrist range of motion, visual analogue scale (VAS), the quick-disabilities of the arm, shoulder and hand (Q-DASH), and Mayo wrist functional score before and after arthroscopy. Patients were visited at 3, 6, 12 weeks intervals after surgery and every six months thereafter. The most frequent diagnoses were triangular fibrocartilage complex (TFCC) injury, dorsal wrist ganglion cyst and Kienbock disease which were treated with accordant arthroscopic methods. Major and minor complications of arthroscopy and prognostic factors were evaluated.
Results: Eighty nine patients participated in long term follow-up. The follow-up duration was 19±13 months. At final fallow-up there were 28.6±9.6 degrees improvement in wrist range of motion, 5.1±3.4 reduction in VAS score (P<0.04), 37.9±30 improvement in Mayo functional wrist score (P<0.02) and 47.5±33 reduction in Q-DASH score (P=0.009). 82% of patients were satisfied with postoperative results and 16% experienced recurrence. The preoperative diagnosis was not a prognostic factor for outcome of arthroscopic treatment. The rate of postoperative complications was 31.4%, which most of them were minor and transient complications. The most frequent complication of wrist arthroscopy in our patients was transient hypoesthesia in superficial ulnar nerve territory.
Conclusion: According to our results, wrist arthroscopy have acceptable outcome in TFCC injuries and Kienbock disease. With the ever-expanding list of indications and procedures that can be performed with wrist arthroscopy, it can be considered as an essential diagnostic and therapeutic tool for the orthopedic surgeon.

Abstract
Background: The most common cause of death in thalassemic patients is cardiac involvement especially cardiomyopathy. If the early stages of heart disease in people with thalassemia are diagnosed, mortality of patients reduced significantly. In this case-control study we compare the clinical symptoms, signs and para-clinic finding in thalassemia patients with control group.
Methods: In this case-control study, thalassemia patients who had visited in special clinic of Vali-e-Asr hospital of Birjand University Medical Sciences during January of 2013 to May of 2014 compared with normal subjects. They matched by age and sex. After explaining the aims of the project, the written consent was received from both groups. Clinical examinations including history taking and auscultation of heart and lungs were performed by Pediatrician. Moreover, using the standard methods, the measurement of height, weight and blood pressure were performed. In following, electrocardiography (ECG) was taken in both groups. Also, both groups underwent transthoracic echocardiography by one cardiologist.
Results: 42 thalassemia patients and 42 healthy subjects was compared in this study. Dyspnea was the only different symptom in the two groups. (23.8% in case and 4.8% in control P=0.01) In physical examination respiratory rate (RR) is only higher in patients with thalassemia that controls, but heart rate (HR), abnormal heart and lung sounds were not different significantly between two groups. In ECG, PR interval and QTc interval in patients with thalassemia was longer than healthy subject. In echocardiography, ejection fraction was lower but left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD) and size of the right ventricle and pulmonary artery pressure (PAP) was significantly higher than those in the control group.
Conclusion: According the result of this study, dyspnea was higher in patients with thalassemia from normal subjects and PR interval and QT interval was longer in thalassemic patients. As well as the size of the left ventricle, size of right ventricle, pulmonary artery pressure were higher than normal population. Also, LV ejection fraction was lower in thalassemia than normal population.
