Abstract
Background: Left main coronary artery (LMCA) stenosis is a leading cause of mortality and morbidity in many countries. Metabolic syndrome (MS) is a risk factor for coronary artery disease (CAD). The effects of MS on left main coronary artery stenosis are not well-defined. The aim of this study was to examine the effects of MS on left main coronary artery stenosis.
Methods: A total number of 495 patients who underwent elective coronary angiography in the Catheter Laboratory of Cardiovascular in Shariati Hospital 2008-2010 were included in the study. MS definition was based on the National Cholesterol Education Program (NCEP)- Adult Treatment Panel III (ATP III) criteria. The stenosis in left main coronary arteries was determined by examining the coronary angiograms of the patients.
Results: The study population consisted of 249 (50.3%) men, and 246 (49.7%) women. The mean age of the participants was 58.01±10 years. MS was present in 86 (17.4%) of the patients based on NCEP- ATP III criteria. LMCA stenosis was seen in 25 (5%) patients. A positive correlation was found between MS and LMCA stenosis (r=0.305, P=0.012). Moreover, a positive correlation was found between age (r=0.192, P=0.05), sex (r=0.334, P=0.007), smoking (r=0.336, P=0.01) and diabetes (r=0.253, P=0.03) and LMCA stenosis.
Conclusion: The metabolic syndrome correlates with LMCA stenosis. LMCA stenosis and its correlation with MS is precipitated by high FBG, age, male sex, and smoking which may synergistically increase the risk for the disease.

Abstract
Background: Persistence of left ventricular hypertrophy (LVH) in renal transplant recipients is associated with unfavorable outcomes. Calcineurin-inhibitor (CNI) nephrotoxicity is a major cause of morbidity and mortality after kidney transplantation. In this study we compared sirolimus (SRL) with calcineurin-inhibitor as primary immunosuppressants for the attenuation of left ventricular hypertrophy in renal transplantation recipients.
Methods: In this prospective cohort study done in Shariati Hospital in 2010, we evaluated the effects of sirolimus and CNI on LVH of 55 renal transplant recipients. The cases (19) received sirolimus while the controls (36) received CNI while being matched for age and duration of transplantation. Data regarding blood pressure (BP), hemoglobin, serum creatinine, uric acid and lipid concentrations were assessed and changes in left ventricular (LV) mass were evaluated by echocardiography over a one-year follow-up.
Results: Left ventricular mass significantly decreased (P=0.0001) in the SRL group but blood pressure did not differ between the two groups. LV mass and LV mass index both decreased significantly (P≤0.05) but the difference was not associated with changes in BP. The difference in interventricular septal thickness at end diastole (IVSD) and posterior wall diameter (PWD) were significant (P≤0.05) in the SRL group but the difference in end diastolic diameter (EDD) was not significant.
Conclusion: Conversion from CNI to SRL-based immunosuppressive therapy in RTRs is safe and SRL may decrease LVH. SRL seems to be safe and improve renal function without cardiac compromise in kidney transplant recipients.

Abstract
Background: Endothelial dysfunction can influence fertility rate in women with polycystic ovary syndrome (PCOS) as flow mediated dilatation (FMD) is impaired in patients with the disease. The aim of this study was to compare two methods of ovulation induction by letrozole or letrozole plus human menopausal gonadotropins (HMGs) in infertile women with PCOS who were resistant to clomiphene citrate based on brachial artery ultrasound findings.
Methods: In this double -blind randomized clinical trial, 59 infertile women who had the inclusion criteria for PCOS were evaluated in the Infertility Clinic of Shariati Hospital in Tehran, Iran in 2010-2011. The patients were assigned to two letrozole and letrozole plus HMG groups and were evaluated for FMD in the brachial artery by transvaginal ultrasonography. Later, the values were recorded and analyzed statistically.
Results: In the letrozole group, infertility treatment was successful in 15 (57.7%) but it failed in 11 (42.3%) patients. In letrozole plus HMG group, the treatment was successful in 18 (54.5%) while it failed in 15 (45.5%) patients. The mean FMD values in the groups with successful and unsuccessful treatment results were 19.42±10% and 18.57±7.2%, respectively, but the difference was not statistically significant (P=0.712). Moreover, the average endometrial thickness in groups with successful and unsuccessful treatment results were 8.4±1.3 mm and 9.8±3.9 mm, respectively but the difference was not significant either (P=0.06).
Conclusion: In infertile women with polycystic ovary syndrome that are resistant to clomiphene, letrozole or letrozole combined with gonadotropin can be equally effective for ovulation induction.

Abstract
Background: The purpose of this study was to determine the prevalence and associated factors for postoperative pulmonary complications (PPCs) and extubation failure in patients having undergone intracranial surgery.
Methods: In this retrospective study done in Firozgar Hospital during 2008-2010, we followed up 254 patients through a clinical questionnaire and observation of the clinical course of participants in pre- and post-operative periods.
Results: Overall, 40 (15.74%) patients had postoperative pulmonary complications. The most common PPC was pneumonia, which was seen in 24 patients (60% of complications). The average duration of ventilation in patients with PPC was significantly higher (16.8.±10 vs. 5.09±4.5 days P=0.001) than patients without the complication. The mean Glasgow coma scale (GCS) after surgery in patients with PPC was significantly lower (11.±4 vs. 13.2±3 P=0.001) than the rest of the patients. Moreover, the mean age of patients with PPC was significantly higher (64.02±14 vs. 41.6.±17 years P=0.001). Average duration of stay in ICU in patients with PPC was also higher (24.±27 vs. 8.7±0.5 P=0.001).
Conclusion: GCS before surgery and failed extubation independently of other variables were significantly associated with pulmonary complications independent of other variables.

Abstract
Background: Induction of medical abortion during the second trimester of pregnancy is considered under certain medical conditions. Abortion in the second trimester of pregnancy could be accompanied by several side effects including hemorrhage and placenta retention. Several types of medications including oxytocin, ergots, and prostaglandins are used to control and optimize the third stage of labor and condition of delivery. The aim of this study was to compare the efficacy of intravenous oxytocin versus rectal misoprostol for the management of the third stage of labor during pregnancy termination.
Methods: In this randomized clinical trial, 80 pregnant women between 14 to 24 weeks of gestational age were randomly assigned into two intervention groups. Twenty units of intravenous oxytocin was used as the standard regimen and it was compared with 400 µg of rectal misoprostol to manage the third stage of labor.
Results: In this study, the frequency of placenta retention was significantly (P=0.034) lower in the misoprostol group (n=3, 7.5%) compared with oxytocin group (n=10, 25%). The average duration of placenta delivery was significantly lower in the misoprostol group (7.95 min Vs. 19.22 min, respectively P=0.015). Decreases in hemoglobin concentration was not significantly different between the two groups.
Conclusion: Generally, management of the third stage of labor in second-trimester abortions could reach a better outcome, regarding lower risks of placenta retention and duration of delivery, if rectal misoprostol is administered instead of intravenous oxytocin.

Abstract
Background: Evaluation of diastolic dysfunction and its relationship with TIMI frame count in patients with stable coronary artery disease referred to Ayatollah Taleghani Hospital in Tehran in the years 2010-2011 is the purpose of this study.
Methods: Patients were divided into two groups: case and control. Both groups had chronic angina. Patient information on check list has been studies based on data provided by angiography and echocardiography methods.
Results: Cases had significantly higher values of corrected TIMI frame count (TFC) for the left anterior desending artery (LAD), TFC for Circumflex artery (Cx) & Right coronary artery (RCA), (mean TFC P<0.001). Conventional echocardiography showed significantly lower maximal peak systolic velocity (sm) (cm/s), Correlation of early diastolic velocity at myocardial segments (Em) & peak systolic velocity at myocardial segments (Sm) with mean TFC in all 3 vessels were significant (P=0/0001). Ratio of maximal early to late diastolic filling (E/A), in patient with TFC≥ 21 was 0/7 & in patients with TFC≤21 was 1. DT (Deceleration time) had no significant correlation with TFC. Mean of isovolumetric relaxation time (IVRT) in cases was 91 m/s & in controls was 72 m/s Which was higher in patients with mean TFC ≥21. Correlation between mean of angiography and diastolic disfunction was significant.
Conclusion: According to this study diastolic dysfunction which estimated by echocardiography showed significant correlation with TIMI frame count in chronic stable angina patients. Due to simplicity, low cost, quality and reproducibility of this method, this will be helpful.

Abstract
Background: Previous reports showed that nucleus accumbens involved in the etiology and pathophysiology of major depression, anxiety and addiction. It is not clear that how these mechanisms occur in the brain. In the present study, the influence of direct nicotine injection in the nucleus accumbens in rats’ anxiety-related behavior was investigated.
Methods: Wistar rats were used in this study. Male Wistar rats bred in an animal house, in a temperature-controlled (22±2 ◦C) room with a 12 hour light/darkcycle. Rats were anesthetized using intraperitoneal injection of ketamine hydrochloride and xylazine, then placed in an stereotactic instrument for microinjection cannula implantation The stainless steel guide cannula was implanted bilaterally in the right and left dorsal the nucleus accumbens shell according to Paxinos and Watson atlas. After recovery, anxiety behavior and locomotor activity were tested. We used the elevated plus maze to test anxiety. This apparatus has widely been employed to test parameters of anxiety-related behaviors including the open armtime percentage (%OAT), open arm entries percentage (%OAE), locomotor activity and we record effect of drugs after injection directly in the nucleus accumbens on anxiety-related behavior.
Results: Experiments showed that bilateral injections into the nucleus accumbens Nicotine, acetylcholine receptor agonist, dose 0.1 of the dose (0.05 and 0.1, 0.25, 0.5) microgram per rat caused a significant increase in the percentage of time spent in the open arms (%OAT), compared to the control group. We did not record any significant change locomotor activity and open arm entries percentage (%OAE) in rats.
Conclusion: Nicotinic receptors in the nucleus accumbens shell involved to anxiety-like behavior in male rats.

Abstract
Background: Endometrioma of ovary is one of the common diseases during reproductive age and the effect of laparoscopic cystectomy of endometrioma on infertility is still matter of debate. We designed this case control study to evaluate the ovarian response to controlled ovarian hyperstimulation during IVF (In vitro fertilization) cycle following laparoscopic unilateral cystectomy of endometrioma.
Methods: In a case control study, we enrolled 30 women with history of unilateral laparoscopic cystectomy of ovarian endometrioma in stripping method who underwent IVF cycle in women Hospital, 2009-2012. The numbers of follicles in response to controlled ovarian hyperstimulation during IVF cycle in the ovary with history of unilateral laparoscopic cystectomy of endometrioma were compared with those from the contralateral ovary.
Results: The mean age (±SD) of patients was 32.3 (±3.4). The mean (±SD) diameter of excised ovarian endometrioma was 42.4 (±10.4) mm. Interval since ovarian surgery to induction ovulation was 2.7 (±2.6) years. Mean number of follicles in the ovary with history of unilateral laparoscopic cystectomy of endometrioma was 2.5 (±1.2) with the range of 1 to 5 and in the control ovary 3.9 (±1.4) with the range of 1 to 6. There was significant difference in the number of follicles in the ovary with laparascopic cystectomy of endometrioma compared with opposite one (P<0.001).
Conclusion: Laparoscopic cystectomy for unilateral endometrioma is associated with a reduced ovarian response to controlled ovarian hyperstimulation during IVF cycle. We did not find any statistically significant difference in reduced ovarian response with regard to patients age, body mass index, size and location of the cyst, and time duration since ovarian cystectomy.

Abstract
Background: Detection of retained foreign bodies remains a significant problem in the emergency department. Foreign bodies can go undetected causing infectious complications ultrasonography is too inaccessible and expensive. The purpose of this study is comparison of ultrasonography with radiography for the detection of cervical esophageal foreign bodies
Methods: This cross-sectional study evaluated 58 patients referred with suspected upper esophageal foreign body in the Emergency Department, Amir Alam. Patients were evaluated with ultrasonography and x-ray. After surgical exploration, different type of foreign bodies were recorded. The SPSS statistical software was used for analysis. For applicable efficacy outcome measures, a Spearman correlation was used. Differences were significant when P<0.05. All values were expressed as the frequency and present.
Results: Fifty eight patients were studied. 25 patients (43.4%) were male and 31 patients (56.9%) were female, in 28 (48.2%) patients foreign bodies were detected in radiography. 30 patients (51.8%) were not recorded in techniqe. It was found in patients 22 (78.6%) organic body, and six cases (21.4%) non-organic body. radiographic outcomes in patients with foreign bodies were positive in 26 patients (92.9%) and in two patients (7.1%) were negative. Ultrasound results were positive in 27 patients (96.4%) and in one patient (3.6%) were negative. Association of ultrasound and radiography results were significant in patients with foreign body (Spearman correlation=0.896, P=0.001 Kappa=0.890).
Conclusion: These reports suggest that result of ultrasound with radiography for the detection foreign bodies in cervical esophagus have good agreement. The use of ultrasonography in the emergency department to detect and eventually remove foreign bodies by emergency physicians is an important issue because there is not always an ultrasound technologist or radiologist available.

Abstract
Background: Recent studies have suggested that impaired fetal growth are indicators that may be present in the first trimester. The aim of this study was to investigate the relationship between crown-rump length (CRL) and pregnancy associated plasma protein-A (PAPP-A) measurements in first trimester for low birth weight (LBW).
Methods: This prospective cohort study were on 120 pregnant women in first pregnan-cy trimester, in Women's Hospital Mirza Kochak Khan in 2011-2012. Gestational age according to crown-rump length and gestational age according to last menstrual period (LMP), neonatal weight, small for gestational age, pregnancy associated plasma protein-A and low birth weight were recorded. Main outcome measures was weight and gestational age at birth. Statistical tests used included descriptive statistics, t-test, χ² and all tests were two-tailed and differences with P<0.05 were considered to be statistically significant.
Results: Our findings showed that a total of 120 cases were included CRL Z-score and log 10 (MOM PAPP-A) were positively correlated with fetal birth weight. The mean Crown-rump length Z-score was significantly can be reduced in LBW in first trimester pregnancy. (P<0.001) Mean PAPP-A in low birth weight was (0.4±0.11 MOM), but in normal weight infants was (1.04±0.7 MOM). (P=0.011) also mean PAPP-A in pregnant women with SGA infants is significantly less than other pregnant women (0.5±0.2 versus 1.1±0.7) (P<0.001).
Conclusion: Our data suggest that crown-rump length and maternal levels of PAPP-A measured during the first trimester are independent factors that influence fetal birth weight. But their predictive powers are not sufficiently good for them to be used alone for low birth weight screening.

Abstract
Background : Chemotherapy-induced nausea (CIN) in the anticipatory and acute phase is the most common side effect in cancer therapy. The purpose of this study was to investigate the effect of ginger capsules on the alleviation of this problem.
Methods : This randomized, double-blind, placebo-controlled clinical trial was performed on 80 women with breast cancer between August till December 2009 in Imam Khomeini Hospital, Tehran, Iran. These patients underwent one-day chemotherapy regime and suffering from chemotherapy-induced nausea. After obtaining written consent, samples were randomly assigned into intervention and control groups. Two groups were matched based on the age and emetic effects of chemotherapy drugs used. The intervention group received ginger capsules (250 mg, orally) four times a day (1 gr/d) and the same samples from the placebo group received starch capsules (250 mg, orally) for three days before to three days after chemotherapy. To measure the effect of capsules a three-part questionnaire was used, so the samples filled every night out these tools. After collecting the information, the gathered data were analyzed by statistical tests like Fisher’s exact, Kruskal-Wallis and Chi-square using version 8 of STATA software.
Results : The mean ± SD of age in the intervention and placebo groups were 41.8 ± 8.4 and 45.1 ± 10 years, respectively. Results indicated that the severity and number of nausea in the anticipatory phase were significantly lower in the ginger group compared with placebo group (P=0.0008, P=0.0007, respectively). Also, the intensity (P=0.0001) and number (P=0.0001) of nausea in the acute phase were significantly lower in the ginger group. On the other hand, taking ginger capsules compared with placebo did not result in any major complications.
Conclusion: Consuming ginger root powder capsules (1 gr/d) from three days before chemotherapy till three days after it in combination with the standard anti-emetic regimen can help to reduce the anticipatory and acute nausea.

Abstract
Background: To compare the success rate and side effects of letrozole and misoprostol versus misoprostol alone for medical termination of early pregnancy.
Methods: The patients requesting termination of pregnancy up to 63 days of gestation were randomized into two groups. The letrozole group received letrozole 10 mg daily for 3 days followed by 800 micrograms of vaginal misoprostol, while the placebo group received placebo for 3 days followed by the same dosage of misoprostol. The complete abortion rate and the side effects profiles of the two groups were compared. The primary outcome measure was the abortion rate.
Results: A total of 214 women were recruited. Overal complete abortion rate was 81.3%, complete abortion rate in the letrozole group was not significantly higher than that of the placebo group (84.1% compared 78.5%). After receiving 800 mcg misoprostol, 37 case (17.3%) had complete abortion that 13 cases (12%) of the misoprostol group and 24 patients (22.5%) of the cominabtion group and after receiving 1600 mcg, misoprostol, in 137 cases (77.4%) had complete abortion that 71 patients (75.5%) of the misoprostol group and 66 cases (79.5%) was obtained for the combination group. This difference was not statistically significant (P> 0.05). D & C in 40 cases (18.7%) reported that was not significantly different in the two groups, 17 cases (15.9 %) in the combination group versus 23 (21.5%) in the misoprostol group. Side effects such as fever, tachycardia, diarrhea and pain were similar in the two groups there were not significantly fewer women complaining of side effects in the letrozole group than those in the placebo group (P> 0.05).
Conclusion: Combination of letrozole and misoprostol is as effective as misoprostol alone in complete abortion rate. Based on these results, the use of misoprostol in combination with letrozole is safe and not expensive.

Abstract
Background: Acute respiratory distress syndrome (ARDS) is one of the most important complications associated with traumatic brain injury (TBI). ARDS is caused by inflammation of the lungs and hypoxic damage with lung physiology abnormalities associated with acute respiratory distress syndrome. Aim of this study is to determine the epidemiology of ARDS and the prevalence of risk factors.
Methods: This prospective study performed on patients with acute traumatic head injury hospitalization in the intensive care unit of the Shohaday-e Haftom-e-Tir Hospital (September 2012 to September 2013) done. About 12 months, the data were evaluated. Information including age, sex, education, employment, drug and alcohol addiction, were collected and analyzed. The inclusion criteria were head traumatic patients and exclusion was the patients with chest trauma. Questionnaire was designed with doctors supervision of neurosurgery. Then the collected data were analysis.
Results: In this study, the incidence of ARDS was 23.8% and prevalence of metabolic acidosis was 31.4%. Most injury with metabolic acidosis was Subarachnoid hemorrhage (SAH) 48 (60%) and Subdural hemorrhage (SDH) was Next Level with 39 (48%) Correlation between Glasgow Coma Scale (GCS) and Respiratory Distress Syndrome (ARDS) were significantly decreased (P< 0.0001). The level of consciousness in patients with skull fractures significantly lower than those without fractures (P= 0.009) [(2.3±4.6) vs (4.02±7.07)]. Prevalence of metabolic acidosis during hospitalization was 80 patients (31.4%).
Conclusion: Acute respiratory distress syndrome is a common complication of traumatic brain injury. Management and treatment is essential to reduce the mortality. In this study it was found the age of patients with ARDS was higher than patients without complications. ARDS risk factor for high blood pressure was higher in men. Most victims were pedestrians. The most common injury associated with ARDS was SDH. Our analysis demonstrates that Acute respiratory distress syndrome is common after traumatic brain injury. Management of traumatic brain injury is necessary to manage and reduce the mortality.

Abstract
Background: Cesarean delivery is the most common surgical procedure and this prevalence is on the rise. Given these trends, cesarean wound complications, such as disruption or infection, remain an important cause of post-cesarean morbidity.
Methods: We conducted a single-center randomized controlled trial that included women with viable pregnancies (≥24 weeks) undergoing cesarean delivery at Motahary University Hospital, Urmia, Iran from April to November 2014. All cesarean types were included: scheduled or unscheduled and primary or repeat cesareans. Women were excluded for the following reasons: inability to obtain informed consent, immune compromising disease (e.g. AIDS), chronic steroid use, diabetic mellitus and BMI≥30. Of 266 women, 133 were randomized to staples and 133 women to suture group.
Results: The mean±SD age of the staples group was 27.6±5.4 years and mean±SD age of suture was 28.7±5.9 years. Multiparity is the most frequent in both groups that by using Chi-square test, no significant differences were observed between the two groups (P=0.393). The most frequent indication for cesarean section in both groups was history of cesarean section in staple 40 cases (30.1%) and suture 32 cases (24.1%). The survey was conducted using the Chi-square test was not significant (P=0.381). Pain at 6 weeks postoperatively was significantly less in the staple group (P=0.001). Operative time was longer with suture closure (4.68±0.67 versus 1.03±0.07 minute, P<0.001). The Vancouver scale score was significantly less in suture closure (6.6±0.8 versus 7.5±0.9, P=0.001). Wound disruption was significantly less in suture closure (3.8% versus 11.3%, P=0.017).
Conclusion: The staple group had low pain and operation time but had a significant wound disruption and scar. The patients who have suffered a significant wound disruption were affected by age (P=0.022) and BMI (P=0.001) at compared those who were not affected by factors such as age or high BMI as risk factors for open surgical wound.

Abstract
Background: To assess patient' reaction towards bedside teaching in the nephrology ward of Imam Khomeini Hospital Complex (Tehran) and to identify the factors that may influence it.
Methods: A cross-sectional study was conducted in the nephrology ward of Imam Khomeini Hospital Complex from march to September, 2014. All inpatients present on the day of the study were interviewed using a structured questionnaire.
|
Results: 146 patients were examined in this study that 62 patients (42.5%) were women and 84 cases (57.5%) were men. 112 (76.7%) of patients had a good feeling about the training to physicians. The behavior of students was evaluated respectful by 132 individuals (90.4% of patients). Total number of 106 individuals (72.6% of patients) had trusted to the health care team and 120 people (82.2% of patients) knew that the physicians’ behaviors are associated with the respect to their religious beliefs. Not being same sex of the examiners was important for 47 individuals (32.2% of patients). The number of 123 cases (84.2% of patients) evaluated the physicians' behavior with respect to their privacy. The number of 119 individuals (81.5% of patients) received their responses from the examiners. Statistical tests indicate a significant relationship between the respectful behavior of students with patient and good feeling about training to physicians, so that the 95.5% of people who have seen the respectful behavior of students to oneself had a good feeling about training to physicians (P˂0.001). The relationship between the presence of teacher with students and good feeling on training to physicians was significant (P=0.013). Positive feeling about practicing physicians was associated with patient age. So the age average of people who feel good about practicing physicians was significantly lower than the other people (47.2±17 versus 55.6±18 and P=0.028).
Conclusion: The relationship between respectful behavior and presence of teacher with students and age and good feeling on training to physicians was significant.

Abstract
Breast cancer is the most common cancer among women and the earlier it is diagnosed, the easier it is to treat. The most common way to diagnose breast cancer is mammography. Mammography is a simple chest x-ray and a tool for early detection of non-palpable breast cancers and tumors. However, due to some limitations of this method such as low sensitivity especially in dense breasts, other methods such as 3d mammography, ultrasound and magnetic resonance imaging are often suggested to obtain additional useful information. Recently, computer-aided diagnostic or intelligent diagnostic have been developed to assist radiologists to improve diagnostic accuracy. In general, a computer system consists of four steps: pre-processing, dividing areas of interest, extracting and selecting features, and finally classification. Nowadays, the use of imaging techniques in the identification of patterns for diagnosis and automatic determination of breast cancer by mammography and even digital pathology (which is one of the emerging trends in modern medicine) reduces human errors and speeds up the diagnosis. In this article, We reviewed recent findings and their disadvantages and benefits in the diagnosis of breast cancer by neural networks, especially the artificial neural network, which is widely used in the diagnosis of cancers and intelligent breast cancers. This literature review shows that hybrid algorithms have been better at improving classification and detection accuracy. Providing a convenient way to diagnose tumors in the breast by computer-assisted diagnosis systems will be of great help to the physicians. Much work has been done in recent years to diagnose breast cancer, and many advances have been made in improving and diagnosing breast cancer by computer. All methods have a significant error percentage and are different depending on the type of breast, but compared to other types of neural networks, convolution and combining methods with convo have better results. Another advantage of the convoluted network is the automatic extraction of desirable features. Today, the best percentages of accuracy in detecting benign or malignant cancerous mass are achieved by convolution.

Abstract
Background: Spinal anesthesia is a type of neuraxial anesthesia that brings ample benefits. However, due to the fear of this type of anesthesia, many pregnant people refuse to experience it. In this study, we aimed to investigate the levels and causes of fear of spinal anesthesia in candidates for cesarean section.
Methods: The current study is a cross-sctional study performed on 67 patients undergoing cesarean section who were referred to the operation room of Shariati Hospital, in Tehran from September 2018 to September 2019. Matthey questionnaire, which consisted of three sections (demographic information, history of spinal anesthesia and fear of anesthesia), was filled out by candidates and after collecting information, the data were analyzed by SPSS software.
|
Results: Pain over the surgery showed a significant relationship with the history of spinal anesthesia in 4 pregnant women (12.9%) and in 25 women (65.8%) without a history of anesthesia (P<0.0001). In addition, the fear of being awake and looking at the cesarean section during surgery was significant in 7 patients (22.6%) with a history of spinal anesthesia and 18 patients (47.4%) without a history of disease (P<0.0001). Fear of anesthesia needle was also significantly observed in 7 patients (23.3%) with a history of spinal anesthesia and 23 patients (60.5%) with no history of spinal anesthesia (P<0.0001). Fear of back injury was seen in 9 candidates (29%) of patients with a history of spinal anesthesia and in 23 patients (60.5%) of patients without a history of anesthesia (P<0.033). The results of our study also showed a significant relationship between the history of general anesthesia and fear of nausea and vomiting (P<0.046) as well as fear of anesthesia needles (P<0.001).
Conclusion: Patients with a history of spinal anesthesia were significantly less afraid of feeling pain during surgery, seeing surgery, spinal anesthesia needles, and spinal impairments. Moreover, patients with a history of general anesthesia were significantly more afraid of spinal anesthesia, nausea and vomiting than others.

Abstract
Background: Preventing the cancellation of surgeries is an important and devastating challenge in operating room management. Cancellation of pre-scheduled surgeries at the last moment in the operation room leads to increased length of stay, patient dissatisfaction, human resource consumption and financial burden for patients and the health care system. In this study, we have investigated the effect of recording the causes of surgery cancellations in the operation room on the incidence of surgery cancellations in patients who have been candidates for non-emergent surgeries.
Methods: A total of 545 surgeries which had been canceled in different types of surgery between March 2014 and March 2015 were recorded according to the reasons for cancellation in predetermined forms and the information was analyzed. The most common reasons for cancellation included changing the plan of treatment from surgery, a high-risk comorbidity with a high probability of mortality, patient’s refusal from surgery, an unanticipated duration of previous surgery longer than anticipated, the unavailability of an ICU bed in the hospital, requested laboratory data not being ready, failing to prepare requested packed RBCs and other hospital or patient-related problems.

Results: The percentage of surgery cancellations in most groups including orthopedics, urology, cardiac surgery, general surgery, gynecology and maxillofacial surgery, decreased during the course of this study. According to our findings the most relevant cause of non-emergent surgery cancellation was the unpredictable increased duration of previous surgery. The maxillofacial surgery group reached the highest surgery cancellation reduction rate and the cardiovascular surgery group experienced the lowest cancellation reduction rate. Also, the percentage of surgery cancellations in the field of neurosurgery increased during the study period.
Conclusion: Recording the reasons mentioned by the surgical team as the reason for canceling surgeries and reducing the rate of their occurrence during the study and providing appropriate feedback and dialogue in this case had a positive effect on reducing the rate of cancellation of the surgeries and reducing the mentioned reasons.

Abstract
Background: Systemic Sclerosis (SSc) is an autoimmune disease with multi-organ involvement mostly due to fibrosis and ectopic or excessive collagen fibers production in organs. Myocardial fibrosis is the main finding of cardiac involvement in patients with systemic sclerosis. In recent studies, the presence of Fragmented QRS complexes (FQRS) has been shown in the surface electrocardiogram in relation to fibrosis.
Methods: The present study is a case-control study during March 2019 to February 2020 that was conducted in 148 patients with scleroderma referred to the Rheumatology clinic in Shariati Hospital and 101 non-ischemic individuals in the control group matched by age and sex with the patient group. All the medical records were reviewed and those who were low risk according to 10-year atherosclerotic cardiovascular disease (ASCVD) risk assessment were selected as case groups. Data of ECG were evaluated for availability of FQRS or conductive abnormalities and calculating PR, QRS, QT, QTc and Tp-e intervals.
Results: Of the 141 patients with systemic sclerosis, 127(85.81%) were female and 21(14.19%) were male. In the control group, 81 women (80.2%) were present. 61(41.2%) of patients with scleroderma and 8(7.9%) of the control group in this study had FQRS changes in their electrocardiogram. In this study, QRS, QTc and Tp-e intervals were significantly higher in patients with systemic sclerosis compared to those in the control group. The frequency of FQRS, LAHB and LPHB in patients with systemic sclerosis was significantly more than control group. The relationship between PR, QRS, QTc, Tp-e intervals with age, length of disease onset and the severity of skin involvement was assessed. There was a significant correlation between PR-interval and age. Furthermore, there were a correlation between QRS interval and Rodnan skin score, Pulmonary Artery Pressure and Finger to Palm. It is also a meaningful correlation between QTc interval and Rodnan score.
Conclusion: The FQRS finding in electrocardiogram in patients with systemic sclerosis, which has no obvious cardiac symptoms, may indicate myocardial fibrosis and predict future cardiac disorders. |
