@article{ author = {Kadkhodaei, Hamid Reza and Vasigh, Mahtab}, title = {Retrospective study of management of chronic organized empyema with thoracoscopy versus thoracotomy}, abstract ={ Background: Empyema remains a challenging issue for thoracic surgeons. In the early stages of empyema antibiotic therapy and pleural space drainage are the treatment of choice. In organized empyema with pleural peel and re-expandable underlying lung, decortication is the procedure of choice. There is agreement about the value of Video Assisted Thoracoscopic Surgery (VATS) in the management of stages I and II empyema, but there are doubts about its efficacy in stage III empyema. We seek to evaluate the comparative merits of thoracoscopic versus open decortication in the surgical management of patients with chronic postpneumonic pleural empyema.  Methods: From March 2004 to December 2010, 50 patients (43 males, 7 females, mean age: 37.6 years, range: 13-75 years) with chronic postpneumonic pleural empyema underwent decortications. It was a retrospective cross-sectional study. The data was gathered by investigating the patients medical records and analysed by SPSS17. Results: Decortication was performed by open thoracotomy in 29 (58%) patients and VATS in 21 (42%). Mortality was 6.5% .There was no difference in terms of re-operation, mortality and success rates. The operation time in (OT) thoracotomy group was shorter (p=0.03). Hospital stay, drainage duration and antibiotic therapy in VATS group was shorter. There was no statistical difference in regard to the success rate between the two groups. Conclusion: According to the results of this study we found that success rate of VATS decortication is comparable to open thoracotomy, however, a multicentric-randomized trial should be performed before video thoracoscopic decortication becomes the gold standard for the treatment of pleural empyema.  }, Keywords = {Thoracotomy, Thoracoscopic surgery, Empyema, Decortication.}, volume = {19}, Number = {105}, pages = {1-7}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-2394-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-2394-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2013} } @article{ author = {Vahabi, Zahra and Nafisi, Shahriar and Safarian, Fatemeh and Safarian, Zahra and Amirzargar, Ali Akbar and Soltanzadeh, Akbar and Sikarodi, Hajir}, title = {Serologic and electrophysiologic evaluation of patients with Myasthenia gravis}, abstract ={ Background: Myasthenia gravis is an autoimmune disorder mainly caused by antibodies to the muscle acetylcholine receptors (AChR-Ab) at the neuromuscular junction. Loss of these receptors leads to a defect in neuromuscular transmission with muscle weakness and fatigue. This antibody is not detected in all the patients and electrophysiologic study is necessary in some patients as a diagnostic tool. The serologic and electrophysiologic tests in Myasthenia gravis are evaluated in this study. Methods: One hundred twelve patients entered in a cross-sectional study. Serum AChR-Ab was measured and Repetitive nerve stimulation (RNS) was done. The frequency of positive AChR-Ab and abnormal RNS and the relationship between them were determined.   Results: Thirty (26.8%) patients were males and 82 (73.2%) were females. Mean of age was 37.6±15.4 years. AChR-Ab was positive in 71 (63.4%) and negative in 41 (36.6%). RNS was done in 101 patients and was abnormal in 74 (73.3%) and normal in 27 (26.7%) patients. Ratio of abnormal RNS was 84.4% and 53.7% in seropositive and seronegative patients, respectively (p=0.001).  Conclusion: There is significant relationship between serologic and electrophysiological findings in Myasthenia gravis.

There are known risk factors for MS. However, there is uncertainty in its protective factors. Few studies have demonstrated that some chronic infections may have protective effects on this disease. We carried this study to investigate the relation between Helicobacter pylori (HP) infection and the prevalence and severity of MS. Methods: In this case-control study, 163 MS patients and 150 sex- and age- matched controls were included. Blood samples for IgG and IgM anti HP antibodies were collected from all individuals. Also the Expanded Disability Status Scale (EDSS) was used to evaluate the MS patients. Suitable statistical analysis was applied. Results: A significant difference was observed in seropositivity between these two groups. (p<0.001), but no significant difference was seen in seropositivity between conventional and opticospinal MS (p=0.522). No significant difference was observed in seropositivity among ages (p=0.075) and between genders (p=0.204). A significant difference was seen in EDSS value between seropositive and seronegative patients (p=0.017). Conclusion: We concluded that patients with HP infection had lower incidence of multiple sclerosis and MS patients with HP infection showed lower neurologic complications, which can demonstrate that HP infection may have a protective influence on MS pathogenesis. }, Keywords = {Helicobacter pylori, Multiple sclerosis, Immunological influences, Iranian patients.}, volume = {19}, Number = {105}, pages = {15-20}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-2396-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-2396-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2013} } @article{ author = {Shahmoradi, Mohammad Kazem and Khavaninzadeh, Morteza and MousaviKani, Kaveh}, title = {Catheter related complications and survival among Iranian ESRD patients treated in Hasheminejad hospital 2010-2011}, abstract ={ Background: With the innovative idea of Central Vein Catheter at the end of 80’s, treatment of hemodialysis patients faced a significant change. Nowadays CVC’s are widely used and as a result CVC related complications have become important for surgeons. In this study survival and complications associated with CVC’s have been studied in End Stage Renal Disease (ESRD) patients referring to Shahid Hasheminejad Hospital during 2010-11. Methods: In this cross- sectional and descriptive study,  all documents of ESRD patients’ that had catheter insertion at Hasheminejad Kidney Center during 2010-11 were included and demographic data, catheter related side effects, site of catheter, and duration of catheter utilization were taken from the records and major catheter related complications, reasons of catheter removal were obtained by descriptive analyses. We also calculated survival of catheters by Kaplan-meyer analytic method.  Results: In this study 150 records were enrolled with 122 male and 28 female patients, and a mean age of 56±15 years (range of 19-87 yrs). Regression analyses had shown that increasing age (p=0.003, RR=0.78), Hb (anemia), (p=0.04, RR=0.34), increased BUN (p=0.014, RR=0.37) and Cr (p=0.023, RR=0.45) levels had significant correlation with the side-effects.

In fact, there were six different test conditions. Data was collected by the VICON Motion Analysis system and Force plate set. The Paired T-test was performed to study the effects of groove depth and surface contamination on the Coefficient of Friction (COF) and Fluctuations Rate of Ankle (FRA). Results: The results showed that on slippery and dry surfaces, increase in groove depths leads to increase of COF and decrease of FRA (p<0.05). Also values of COF on slippery surface were less than dry surface significantly (p<0.01).  Conclusion: The aim of this study was to find the groove depth which has the optimal stability.

According to its high prevalence in Iran, using a diagnostic procedure with more rapid result than culture, more sensitive and specific than smear and near to culture can help us to diagnose and treat the disease rapidly and accurately, and thus control it in the community. So we decided to evaluate PCR for the diagnosis of Tuberculosis in Broncho-alveolar Lavage (BAL) and compare it with smear.  Methods: Patients who were admitted at Hazrat Rasoul Akram Hospital during 2 years of 2010-11 with the impression of tuberculosis and underwent bronchoscopy were included.  Their BAL was sent for smear, culture and PCR for tuberculosis diagnosis. Data were analyzed by mean and standard deviation and p Value under 0.05 was considered significant. Results: Forty seven patients with probable pulmonary tuberculosis underwent bronchoscopy. BAL cultures were positive in 6 (12.8%) patients, smears in 5 (10.6%) patients and PCR in 3 (6.4%) patients.
