Urology Journal , 2011,
Abstract: PURPOSE: To evaluate major and minor complications of percutaneous nephrolithotomy (PCNL) and their management in our consecutive cases. MATERIALS AND METHODS: We reviewed medical records of 671 patients who had undergone PCNL in our center from March 2000 to March 2006. The demographic data, stone parameters, PCNL complications, and stone-free rate were evaluated. Multiple parameters were evaluated for their association with PCNL complications using Chi-Square test. RESULTS: Complications occurred in 203 (30.3%) patients; renal parenchymal injury in 103 (15.4%), peri-operative bleeding in 42 (6.3%), late bleeding in 6 (0.9%), renal collecting ducts injury in 35 (5.2%), fever in 7 (1.0%), colon perforation in 2 (0.3%), major vessels injury in 3 (0.4%), pneumothorax in 3 (0.4%), and hemothorax in 2 (0.3%) subjects. Mortality occurred in 1 patient with colon perforation (0.15%).CONCLUSION: Percutaneous nephrolithotomy has low complication rate in experienced hands.

Urology Journal , 2008,
Abstract: Introduction: Circumcision is one of the most common surgical operations throughout the world, and meatal stenosis is one its late complications. We evaluated the topical use of a lubricant jelly after circumcision in boys in order to reduce the risk of meatal stenosis. Materials and Methods: A randomized control trial was performed, in which 2 groups of boys younger the 2 years old underwent circumcision according to the sleeve method. The parents in the study group were instructed to use petroleum jelly on the circumcision site after each diaper change for 6 months. In the control group, no topical medication was used. The children were followed up regularly and evaluated for meatal stenosis, bleeding, infection, and recovery time. Results: A total of 197 boys in each group completed the study. None of the children in the study group but 13 (6.6%) in the control group developed meatal stenosis (P < .001). Infection of the circumcision site was seen in 3 (1.5%) and 23 (11.7%) children of the lubricant and control groups, respectively (P < .001), and bleeding was seen in 6 (3.0%) and 37 (18.8%), respectively (P < .001). The mean time of recovery in the lubricant group was 3.8 ± 1.2 days, while it was 6.9 ± 4.2 days in the control group (P = .03). Conclusion: Based on the findings of this study, it seems logical to use a lubricant jelly for reducing postcircumcision meatal stenosis and other complications.

Urology Journal , 2009,
Abstract: Esophageal atresia is often associated with other anomalies. Hereditary and environmental factors may influence the incidence of associated anomalies, particularly of the urogenital system. We had 63 neonates with esophageal atresia admitted to 2 centers in Hamadan, Iran, from 2002 to 2008. They were 38 girls (60.3%) and 25 boy (39.7%). Tracheoesophageal fistula was present in 54 neonates (85.7%), and other associated anomalies in 10 (15.9%). Cardiac anomalies were found in 7 neonates; anorectal anomalies, in 4; urinary tract anomalies, in 2; and limb anomaly, in 1. Urinary tract anomalies (3.2%) were bilateral polycystic kidney in 1 neonate and unilateral hydronephrosis due to ureteropelvic junction obstruction in another. Both neonates with urinary tract anomalies were female and both had tracheoesophageal fistula, as well. Many of the associated congenital abnormalities influence the management protocol of esophageal atresia, and therefore, should be detected as soon as possible after birth.
Intrathecal Meperidine for Prevention of Shivering During Transurethral Resection of Prostate

Urology Journal , 2007,
Abstract: Introduction: The aim of this study was to investigate low-dose intrathecal meperidine for prevention or alleviation of shivering after induction of spinal anesthesia for transurethral resection of the prostate (TURP). Materials and Methods: In a randomized controlled trial, 80 patients scheduled for TURP under spinal anesthesia were assigned into two groups of case and control. Spinal anesthesia was performed using 75 mg of hyperbaric lidocaine 5% plus meperidine, 15 mg, in the patients of the case group and the same dose of lidocaine plus normal saline in the patients of the control group. Shivering episodes were recorded during the operation and in the recovery room. Data on systolic blood pressure, heart rate, arterial oxygen saturation, and body temperature were collected before the induction of anesthesia; 5, 15, and 30 minutes after the induction; and in the recovery room. Results: Maximum level of sensory block was similar in the patients of the case and control groups. Shivering was not seen in the patients who received meperidine, while in the control group, 11 (27.5%) experienced some degrees of shivering (P = .001). Blood pressure, body temperature, and arterial oxygen saturation did not have a clinically significant change and they were not different between the two groups. Side effects of opioids were unremarkable. Conclusion: Low-dose intrathecal meperidine is effective and safe in reducing the incidence of shivering associated with spinal anesthesia for TURP.

Management Science Letters , 2013,
Abstract: Organizational structure plays an important role on survival of any business units and it is important to understand different factors influencing it. In this paper, we present an empirical study to learn the effects of three parameters including formality, concentration and complexity on organizational performance. The proposed study of this paper is implemented for one of research-based organization located in city of Qom, Iran. There were 120 employees working for this organization and the proposed study of this paper has selected a sample of 100 people, designed, and distributed a questionnaire among them. The proposed study uses two methods of regression analysis as well as structural equation modeling to study the impacts of three variables on organizational performance. The results show that there are some positive and meaningful relationship between formality and concentration from one side and organizational performance from the other side. In addition, there is a meaningful and negative relationship between complexity and organizational performance. The results of structural equation modeling are also consistent with the results of structural equation modeling.

Abstract: Life on the earth is dependent on dynamic interactions between its physical, chemical and biological components. In fact, all the individual processes are responsible for regulating the environmental equilibrium which can provide biosphere for multiple forms of human life. In order to overcome on shortcomings, the use of immobilized cell bioreactor technology which provides a valuable effective for treatment of waste water is discussed. An immobilized system which in this matter is applied is about absorbed or captured microorganisms in a solid substratum to retain them in a reactor or analytical system. The multiply of these immobilized cells is done when by nutrients be supplied and then migrate to the surfaces which are referred to biofilms. The biofilms can be developed on various support systems such as polypropylene pall, rocks, sands, charcoal, ceramics, and glass beads. The controllable reaction vessels which are used for these colonized surfaces are referred to bioreactors. Bioreactors in both up flows and down flows mode which use of either batch or continuous processes principle can be operated. Synchronic with development in biotechnology, there is also an extensive development in the field of bioreactors like: pumped tower loop reactor (PTLR), liquid impelled loop reactor (LILR), multipurpose tower bioreactor (MTB), fluidized-bed and packed-bed bioreactor, that in this article are discussed them.

Abstract: Background:Although several potential risk factors have been discussed, risk factors associated with bacterial colonization or eveninfection of catheters used for regional anesthesia are not very well investigated. Design: The prospective observationaltrial. Setting: Department of Anesthesiology Shaheed Beheshti Hospital Shiraz. Period: From April 2003 to April2004. Materials & Methods:, 297 catheters at several anatomical sites where placed using a standardized technique.The site of insertion was then monitored daily for signs of infection (secretion at the insertion site, redness, swelling,or local pain). The catheters were removed when clinically indicated (no or moderate postoperative pain) or when signsof potential infection occurred. After sterile removal they were prospectively analyzed for colonization, defined as > 15colony forming units. Results: 50 (16.7%) of all catheters were colonized, and 27 (9.1%) of these with additional signsof local inflammation. Three of these patients required antibiotic treatment due to superficial infections. Stepwise logisticregression analysis was used to identify factors associated with catheter colonization. Out of 26 potential factors, threecame out as statistically significant. Catheter placement in the groin (odds-ratio and 95%-confidence interval: 3.4;1.5–7.8), and repeated changing of the catheter dressing (odds-ratio: 2.1; 1.4–3.3 per removal) increased the risk forcolonization, whereas systemic antibiotics administered postoperatively decreased it (odds ratio: 0.41; 0.12–1.0).Conclusion Colonization of peripheral and epidural nerve catheter can only in part be predicted at the time of catheterinsertion since two out of three relevant variables that significantly influence the risk can only be recordedpostoperatively. Catheter localization in the groin, removal of the dressing and omission of postoperative antibioticswere associated with, but were not necessarily causal for bacterial colonization. These factors might help to identifypatients who are at increased risk for catheter colonization.
