Nuclear medicine techniques play an important role in the diagnosis and management of SPN. In the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (PET) using 18-F-FDG, and 11-C-Methionine, and single photon emission computerized tomography (SPECT) using somatostatin receptor scintigraphy, 201-Thallium, and 99m-Tc-MIBI. <br/> Mashhad University of Medical SciencesJournal of Cardio-Thoracic Medicine2345-24471320131001Anterior Trans Cervicothoracic Approach for Complete Resection of Cervicothoracic Mediastinal Neurogenic Tumors7983189110.22038/jctm.2013.1891ENReza BagheriToracic Surgeon,Cardio- Thoracic Surgery & Transplant Research Center, Emam Reza Hospital, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, IranMohammad Taghi Rajabi MashadiGeneral Surgeon,Minimally Invasive and Endoscopic Surgery Research Center, Mashhad University of Medical Sciences, Mashhad, IranHossein Mashhadi NejadNeurosurgeon,Mashhad University of Medical Sciences, Mashhad, IranShima SheibaniGeneral Practitioner, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, IranMaryam SalehiCommunity Medicine Specialist, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, IranJournal Article20130729Introduction:Neurogenic mediastinal tumors comprise a wide range of benign and malignant diseases. A group of these tumors, located at thoracic apex, sometimes spread to cervical spaces causing numerous surgical difficulties. In thoracotomy approaches, due to proximity of the tumors to major blood vessels, complete removal of these tumors from cervical spaces is impossible or may cause intraoperative severe bleeding or other dangerous incidents Because of the adjacent major vessels that are not visible.The aim of this study is to report cases of surgical treatment of such tumors using Anterior Trans Cervicothoracic Approach (ATCA). <br/>Materials and Methods:All patients with neurogenic tumors and cervicomediastinal (CM) spread who underwent surgey with ATCA technique during 2005-2011 were included in our study. Then they were evaluated in terms of age, sex, clinical symptoms, radiological and pathological findings, technical success rate of the surgery, surgical complications and first-year relapse rate after the surgery. <br/>Results:Our study included 10 patients from whom 9 were female and 1 was male (M/F= 1/9) and the mean age was 27 years. The most common symptoms were pain and feeling of a lump. All patients were operated by this technique successfully. The most common pathological finding was neurofibroma (in 5 patients) and surgical complications occurred in 2 patients (20%) (Wound infection in 1 patient and brachial plexus injury in another patient). There was no mortality. Disease relapse was reported in 1 patient ganglioneuroblastoma who underwent surgical resection for the second time. <br/>Conclusion: <br/>Considering the successful removal of the tumors and favorable exposure of major vessels in cervicomediastinal spaces, this technique is recommended to resect mediastinal tumors with spread to cervical spaces. However, a more definite conclusion requires further studies.Mashhad University of Medical SciencesJournal of Cardio-Thoracic Medicine2345-24471320131001The Evaluation of Pulmonary Function Tests in Patients with Polycystic Ovary Syndrome8488189210.22038/jctm.2013.1892ENDavood AttaranPulmonologist, Chronic Obstructive Pulmonary Disease Research Center, Faculty of Medicine, Mashhad University of

As a common endocrine dysfunction, polycystic ovary syndrome (PCOS) could significantly influence the level of sex hormones in PCOS patients. Regarding the possible role of sex hormones in airway physiology, the present study was conducted to survey the effects of PCOS on pulmonary function test parameters. <br/>Materials and Methods: In this cross-sectional study 30 recently diagnosed patients with PCOS without history of pulmonary disease were enrolled and 20 healthy women were considered as the control group according to their age, weight, and height. The patients and the controls underwent body plethysmography to measure pulmonary function tests. <br/>Results: The mean age of the patients and the controls were 29.43±7.8 and 30.0±7.6 years respectively. There were no statistically significant differences in all pulmonary function test parameters between the patients and the controls (p>0.05). After dividing the patients into 2 groups based on their body mass index (BMI), BMIConclusion: Our results showed that pulmonary function test parameters are not different in PCOS patients comparing to healthy women. Only the deleterious effects of high BMI on pulmonary function can be occurred in these patients.Mashhad University of Medical SciencesJournal of Cardio-Thoracic Medicine2345-24471320131001The Evidence of Hyperinflation on Chest X Ray and its Correlation with Air Flow Obstruction in COPD Patients8994189310.22038/jctm.2013.1893ENHassan GhobadiPulmonologist, Emam Khomeini Hospital, Faculty of Medicine, Ardabil University of Medical Sciences, Ardabil ,Iran.Farhad PourfarziCommunity Medicine Specialist, Ardabil University of Medical Sciences, Ardabil, IranHassan AnariRadiologist, Emam Khomeini Hospital, Faculty of Medicine, Ardabil University of Medical Sciences, Ardabil ,Iran.Zohreh Hassani-NassabGeneral Practitioner, Faculty of Medicine, Ardabil University of Medical Sciences, Ardabil ,Iran.Journal Article20130315Introduction: <br/>According to the latest statistical and epidemiological studies, COPD will become the fourth leading cause of death in 2030 worldwide. Scientists are studying on methods to diagnose COPD in the patients in early stages, because it is a curable and preventable disease in early stages. In this study, evidences of hyperinflation on CXR of COPD patients were compared with pulmonary function test (PFT) finding. <br/>Materials and Methods: <br/>This cross-sectional study was done on 100 patients who were referred to the pulmonary clinic with symptoms of chronic cough and dyspnea. After taking history and performing physical examination, demographic information, history of smoking and bakery and frequency of exacerbations were recorded. Standard spirometry was performed and the severity of COPD was determined by GOLD (Global initiative for chronic Obstructive Lung Disease) staging. Additionally, they underwent CXR examination (PA and lateral). Collected data were analyzed in SPSS ver. 18. <br/>Results: <br/>In this study, there were 79 male and 21 female. .. . . The patients, 64% of whom were urban and 36% were rural dwellers. There was significant correlation between FEF50%predict with sterno-diafragmatic angle and retro-sternal lucency (p=0.01, r=-0.26 and p=0.01, r=-0.25 respectively). Also there were significant correlations between the FEV1/FVC with retro-sternal lucency (p=0.006, r=-0.27) and FEV1%predict with sterno-diaphragmatic angle (p=0.002, r=-0.31). <br/>Conclusion: <br/>The study showed some evidences of lung hyperinflation on CXR which significantly associated with PFT parameters. Sterno-diaphragmatic angle and retro-sternal lucency can be used to predict the severity of airway obstruction in patients with COPD, although the CXR finding cannot be substituted for PFT and CT data. <br/> Mashhad University of Medical SciencesJournal of Cardio-Thoracic Medicine2345-24471320131001Atypical Radiological Findings in Patients with Hydatid Cysts of the Lung, Study of 1024 Cases9599190210.22038/jctm.2013.1902ENMajid MirsadraeePulmonologist, Medical school-Islamic Azad University, Mashhad Branch,Mashhad,IranSeyed Ziaollah HaghiThoracic Surgeon,Cardio- Thoracic Surgery & Transplant Research Center, Emam Reza Hospital, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, IranSadegh VaziriGeneral Practitioner, Zakaria Research Center, Medical School, Islamic Azad University , Mashhad Branch ,Mshhad,IranSaeed NaghibiRadiologist, Subspecialty fellow of computed tomography, Assistant professor, Islamic Azad University-Mashhad branch, IranSaeed MirsadraeeSenior clinical lecturer in radiology- Honorary consultant radiologist, Queen`s Medical Research Institute, University of Edinburgh, UKJournal Article20130718Introduction : The objective of this study was to give a description of the most prominent atypical radiological presentations of lung hydatidosis. <br/>Materials and methods: <br/>All patients diagnosed with pulmonary hydatidosis by surgical exploration were included in this study. Standard chest roentgenogram and computed tomography CT) were evaluated before surgery for lung cysts or unknown lesions. Radiological findings were divided into two categories: 1- Typical hydatid cysts that were previously presented by imaging as a hydatid cyst in the form of an intact cyst, water lily sign and crescent sign. 2- Atypical hydatid cysts that were not similar to typical previously mentioned hydatid cysts. <br/>Results: During a 26-year period, 1024 subjects with pulmonary hydatidosis were diagnosed and operated on. Chest X-rays (interpreted in 832 cases) showed perforated cysts in 190 (23%) and atypical findings such as mass, alveolar type infiltration, abscess and collapse in 113 (13%) patients. Seventy-nine patients had a thoracic CT scan in which atypical cysts were detected in 32 subjects (40.5%) such as: thick wall cavity in 9 patients (28%), solid masses in 7 (21%), abscesses in 6 (18%), consolidation in 3 (9%), fungus balls in 3 (9%), collapse (atelectasis) in 2 (6%) and round pneumonia in 2 (6%). Cavity was significantly more frequent in the right lung (90%) and mass-like opacity was significantly more frequent in the lower lung field (100%). <br/>Conclusion: Hydatid cysts should be considered for most of localized radiological pictures of the lung without respect to localization, size and count of lesions.Mashhad University of Medical SciencesJournal of Cardio-Thoracic Medicine2345-24471320131001Effect of Pioglitazone on Plasma Levels of Phenytoin in Rats100103189410.22038/jctm.2013.1894ENHamed GhavimiLiver and Gastrointestinal Diseases Research Center

Patients affected by both type 2 diabetes and epilepsy may be prescribed pioglitazone and an anti-epileptic drug such as phenytoin concurrently. The aim of this study was to consider the interaction of pioglitazone with phenytoin in an experimental model. According to the result of this study, concurrent use of phenytoin and pioglitazone in clinic may cause therapeutic failure of phenytoin which may cause seizures and during seizures the cardiac function may be affected. <br/>Material and Methods: Two groups of rats were treated for 30 days. In group 1 (control group) saline (10 ml/kg) and phenytoin (30 mg/kg) were administered daily by intragastric gavage. In group 2 (test group) , pioglitazone (10 mg/kg) was administered daily 60 minutes before phenytoin (30 mg/kg). Two hours after the last intragastric gavage, animals were anesthetized with ether and 2 ml of blood was drawn from the heart into a syringe containing Ethylenediaminetetraacetic (EDTA), and phenytoin concentration in rat plasma was determined by High performance liquid chromatography (HPLC).The study consisted of 2 groups of 10 male adult Wistar rats. <br/>Results: Compared with control group, concurrent use of pioglitazone and phenytoin was associated with significantly lower mean plasma concentrations of phenytoin : 2.08 ± 0.03 µg/ml <em>VS</em> 1.2 ± 0.02 µg/ml. <br/>Conclusion: Concurrent use of pioglitazone and phenytoin was associated with a significant decrease in plasma concentration of phenytoin in this experimental model. In clinic, this interaction may cause seizures and it has been shown that both cardiac and respiratory functions may affected by seizures.Mashhad University of Medical SciencesJournal of Cardio-Thoracic Medicine2345-24471320131001Acute Myocardial Infarction in a 17-Year-Old Boy Secondary to Lightning Strike104106189510.22038/jctm.2013.1895ENAli AzariCardiac Surgeon, Cardiovascular Research Center, Ghaem Hospital School of Medicine, Mashhad University of Medical Science, Mashhad, IranLeila BigdeluCardiologist. cardiovascular research Center.
