Background: Because of more frequency of suicidal attempts in females, we need to study about its relationship with the female hormones. The aim of this study was to evaluate the serum estrogen and progesterone concentration and their relationship with suicidal attempt ranking in the attempted females. Materials and Methods: The studied cases chose from patients who had referred to clinical toxicology emergency of Noor Hospital (Isfahan, Iran), during 2012, because of suicidal attempt. The estrogen and progesterone serum level of the 111 females were measured during 24 hours after suicidal attempt. The rank of their suicide, the demographic properties, and the menstrual cycle phase of them were also registered, as the patient's statement. The results were analyzed by ANCOVA and Kruscal-Wallis under SPSS16. Results: Mean serum concentration of the estrogen was 76.8 pg/mL, and the mean serum concentration of progesterone was 2.99 ng/mL. Of them, 62.2% were in the luteal phase, and 37.8% were in the follicular phase, as they said. The serum progesterone concentration of the patients with more than two times suicidal attempts was significantly higher than the others. Conclusion: The suicidal attempt ranks significantly related to the serum progesterone concentration and the luteal phase.

Background: Preoperative assessment of anatomical landmarks andclinical factors help detect potentially difficult laryngoscopies. The aim of the present study was to compare the ability to predict difficult visualization of the larynx from thefollowing preoperative airway predictive indices, in isolation and combination: Neck circumference to thyromental distance (NC/TMD), neck circumference (NC), modified Mallampatitest (MMT), the ratio of height to thyromental distance (RHTMD), and the upper-lip-bite test (ULBT). Materials and Methods: We collected data on657 consecutive patients scheduled for elective caesarean delivery under general anesthesia requiring endotracheal intubation and then evaluated all five factors before caesarean. An experienced anesthesiologist, not informed of the recorded preoperative airway evaluation, performed the laryngoscopy and grading (as per Cormack and Lehane's classification). Sensitivity, specificity, and positive and negative predictive values for each airway predictor in isolation and in combination were determined. Results: Difficult laryngoscopy (Grade 3 or 4) occurred in 53 (8.06%) patients. There were significant differences in thyromental distance (TMD), RHTMD, NC, and NC/TMD between difficult visualization of larynx and easy visualization of larynx patients (P < 0.05).The main end-point area under curve (AUC) of the receiver-operating characteristic (ROC) was lower for MMT (AUC = 0.497; 95% Confidence Interval = CI,0.045-0.536) and ULBT (AUC = 0.500, 95% CI, 0.461-0.539) compared to RHTMD, NC, TMD, and NC/TMD score ([AUC = 0.627, 95% CI, 0.589-0.664], [AUC = 0.691; 95% CI, 0.654-0.726], [AUC = 0.606; 95% CI, 0.567-0.643], [AUC = 0.689;95% CI, 0.625-0.724], respectively), and the differences of six ROC curves were statistically significant (P < 0.05). Conclusion: The NC/TM Discomparable with NC, RHTMD, and ULBT for the prediction of difficult laryngoscopy in caes are an delivery.

Background: Several studies have been shown that antidepressant drugs have contradictory effects on cognitive processes. Therefore, the aim of this study was to investigate the effects of amitriptyline and fluoxetine on synaptic plasticity in the dentate gyrus (DG) of the hippocampal formation in rat. Materials and Methods: Experimental groups were the control, the fluoxetine, and amitriptyline. The rats were treated for 21 days and then, paired pulse facilitation/inhibition (PPF/I) and long-term potentiation (LTP) in perforant path-DG synapses were assessed (by 400 Hz tetanization). Field excitatory post-synaptic potential (fEPSP) slope and population spike (PS) amplitude were measured. Results: The results of PPF/I showed that PS amplitude ratios were increased in 10-70 ms inter-stimulus intervals in the amitriptyline group compared to the control group. In the fluoxetine group, EPSP slope ratios were decreased in intervals 30, 40, and 50 ms inter-stimulus intervals compared to the control group. The PS-LTP was significantly lower in the fluoxetine and the amitriptyline groups with respect to the control group. Conclusion: The results showed that fluoxetine and amitriptyline affect synaptic plasticity in the hippocampus and these effects is probably due to the impact on the number of active neurons.

Background: prevention of suicide is one of priority world health. Suicide is one of the preventable causes of death. The aim of this study is evaluation of telephone follow up on suicide reattempt. Materials and Methods : This randomized controlled clinical trial is a prospective study which has been done in Noor Hospital of Isfahan-Iran, at 2010. 139 patients who have suicide attempt history divided in one of two groups, randomly, 70 patients in" treatment as usual (TAU)" and 69 patients in "brief interventional control (BIC). Seven telephone contact with BIC group patients have been done "during six months" and two questionnaires have been filled in each session. The data has been analyzed by descriptive and Chi-square test, under SPSS. Results : No significant differences of suicide reattempt has been found between two groups (P = 0.18), but significant reduction in frequency of suicidal thoughts (P = 0.007) and increase in hope at life (P = 0.001) was shown in intervention group. Conclusion : Telephones follow up in patients with suicide history decrease suicidal thought frequency" and increase hope in life, significantly.

Background: Inadequate pain control has a significant role in maternal and neonatal health in early post-partum period which interferes with breastfeeding and has a negative influence on child normal growth. The aim of this study is evaluation of subcutaneous methadone effectiveness on post-operative pain control. Materials and Methods: Double blind randomized prospective clinical trial involving 60 term pregnancy patients through 2008 to 2009 Undergo cesarean. Inclusion criteria: Prime gravid candidate of elective cesarean and spinal anesthesia class 1 or 2. Known case of drug allergy and methadone interaction, addiction, uncontrolled medical disease excluded. Case group injected 10 mg of subcutaneous methadone in the site of incision before final suture. Morphine was a pain reliever in follow up examination. Data include mean of pain, nausea and vomiting, MAP, etc., collected and analyzed by independent-T test and Man Whitney test. Results: Although mean usage of morphine between groups was not significant statistically but the mean pain severity (P value < 0.05) and mean satisfactory (P value = 0.02) was statistically significant between groups. Other parameters were not statistically significant. Conclusion: We suggest subcutaneous methadone as a safe pain reliever in post cesarean section patients.

Background: Pterygium is a common disorder of the ocular surface. It causes vision impairment -usually irregular type astigmatism- through different mechanisms. In addition, it is believed that surgical excision of the pterygium improves visual problems. The appropriate method to investigate irregular astigmatism is using wavefront analysis. This study was aimed to evaluate wavefront analysis pre and post pterygium surgery. Materials and Methods: This study was performed on 32 patients who underwent surgical excision of pterygium in January 2012. Data were recorded and compared after pre and postoperative comprehensive ophthalmologic examinations including uncorrected and best corrected visual acuity, Orbscan, wavefront analysis and autorefraction to figure out the effects of surgery on different parameters. Results: Comparison of pre and postoperative parameters showed that surgical treatment of the pterygium improves numerous parameters significantly including uncorrected and best corrected visual acuity, spherical and cylinder refractive error, higher order aberration, quadrafoil (Z440), corneal astigmatism and 3 and 5 mm central zone corneal irregularity (all P-values < 0.0001). In addition, it improves vertical coma (P:0.003) and secondary astigmatism (Z420) (P:0.004). Conclusion: It is concluded that surgical excision of the pterygium improves visual acuity, refractive errors and most of the corneal topographic indices and wavefront analysis parameters.

Background: There are considerable attempts worldwide on herbal and traditional compounds to validate their use as anti-cancer drugs. Plants from Moringaceae family including Moringa oleifera possess several activities such as antitumor effect on tumor cell lines. In this study we sought to determine if callus and leaf extracts of M. oleifera possess any cytotoxicity. Materials and Methods: Ethanol-water (70-30) extracts of callus and leaf of M. oleifera were prepared by maceration method. The amount of phenolic compounds of the extracts was determined by Folin Ciocalteu method. The cytotoxicity of the extracts against Hela tumor cells was carried out using MTT assay. Briefly, cells were seeded in microplates and different concentrations of the extract were added. Cells were incubated for 48 h and their viability was evaluated by addition of tetrazolium salt solution. After 3 h medium was aspirated, dimethyl sulfoxide was added and absorbance was determined at 540 nm with an ELISA plate reader. Cytotoxicity was considered when more than 50% reduction on cell survival was observed. Results: Callus and leaf extracts of M. oleifera significantly decreased the viability of Hela cells in a concentration-dependent manner. However, leaf extract of M. oleifera were more potent than that of callus extract. Conclusion: As the content of phenolic compounds of leaf extract was higher than that of callus extract, it can be concluded that phenolic compounds are involved in the cytotoxicity of M. oleifera.

Background: Free radicals are the known mechanisms responsible for inducing colitis with two origins: Inflammatory cells and tissues. Only the inflammatory cells can be controlled by corticosteroids. Our aim was to assess the importance of neutrophils as one of the inflammatory cells in inducing colitis and to evaluate the efficacy of corticosteroids in the treatment of inflammatory bowel disease (IBD). Materials and Methods: Thirty-six mice were divided into six groups of six mice each. Colitis was induced in three groups by exposing them to acetic acid through enema (group 1), ex vivo (group 3), and enema after immune suppression (group 5). Each group had one control group that was exposed to water injection instead of acetic acid. Tissue samples were evaluated and compared based on macroscopic damages and biochemical and pathological results. Results: Considering neutrophilic infiltration, there were significant differences between groups 1, 3, 5, and the control of group 1. Groups 3, 5, and their controls, and group 1 and the control of group 3 had significant differences in terms of goblet depletion. Based on tissue originated H ₂ O ₂ , we found significant differences between group 1 and its control and group 3, and also between groups 5 and the control of group 3. All the three groups were significantly different from their controls based on Ferric Reducing Ability of Plasma (FRAP) and such differences were also seen between group 1 with two other groups. Conclusion: Neutrophils may not be the only cause of oxidation process in colitis, and also makes the effectiveness of corticosteroids in the treatment of this disease doubtful.

Background: In the previous studies, fasting insulin and apo-lipoproteins are considered as one of the risk-factor of coronary artery disease (CAD) but did not have the same results. In this study, we attempted to define the association of high fasting insulin and apo-lipoproteins of serum in non-diabetic patients who were afflicted with coronary arteries disease with severity of coronary arteries involvement. Materials and Methods: This study was conducted between September 2011 and February 2012 on three groups, each one consisting of 100 members while using angiographic scores of Gensini with three equal groups with low, medium, and high stenosis of coronary arteries. The evaluation of non-diabetic patients afflicted with CADs, included the fasting glucose level less than 126 mg/dl or non-consumption of blood glucose reduction drugs or negativity history of diabetes. Results: In this study, there were 300 non-diabetic patients afflicted with CAD in three groups of low, medium, and high extremity. Due to attained results, the patients afflicted with high CAD had a higher level of insulin (18.3 ± 0.8) in relation with low and medium groups (P < 0.001). As it was observed, the level of serum apo-lipoproteins of A1 (APO-A1) in low group of CAD (175 ± 36.4) is meaningfully higher than its quantity in high-CAD group (158 ± 42.4, P < 0.001). Furthermore, the quantity of serum apo-lipoproteins of B (APO-B) in mild CAD group (139 ± 30.4) is meaningfully less than severe CAD group (155.21 ± 29.7, P < 0.001). Conclusion: Our findings show that insulin, APO-A1, APO-B, and total cholesterol measurement is a good case for defining the severity of coronary artery involvement, while high-density lipoprotein, low-density lipoprotein, and triglyceride are not important risk-factors.

Background: Increasing antibiotic resistance of Helicobacter pylori (H. pylori) which is associated with diseases of the upper gastrointestinal tract, has made alternative treatments necessary. This study compares the efficacy of adding N-acetyl cysteine (NAC) to standard regimen for H. pylori eradication. Materials and Methods: We conducted a randomized, open-label trial, comparing the efficacy of 14 days of quadruple therapy with Amoxicillin, Bismuth citrate, Omeprazole, Clarithromycin (group A) versus 14 days of above regimen plus NAC (group B) in adult patients with dyspepsia. Primary objective was H. pylori eradication.Compliance and side effects were determined by questionnaires. Our analysis was by intention-to-treat (ITT) and per-protocol. This study is registered with www.IRCT.ir, number: IRCT201201078634N1. Result: A total of 121 participants aged 21-76 years with a mean age of 44.5 ± 14.1, and 52.9% female, were randomly allocated a treatment: 60 with 14-day standard therapy and 61 with 14-day standard therapy with NAC. The eradication rate in groups A and B with ITT analyses was 49/60 (81.7%; 95% [confidence intervals] CI = 71.6-91.8%) and 50/61 (82%; 95% CI = 72-91.9%), respectively ( P = 0.96). In per-protocol analysis, the rate of H. pylori eradication in groups A and B was 45/54 (83.3%; 95% CI = 73.1-93.6%) and 45/53 (84.9%; 95% CI = 74.9-94.9%), respectively ( P = 0.82). Minor well tolerated side effects were reported in 15 (34.9%) and 21 (35.6%) patients of groups A and B, respectively, and only one therapy cessation in group A was created. Conclusion: Standard 14-day triple-drug therapy with NAC is not preferable to standard drug regimens for H. pylori infection.

Background: Normal bladder function is necessary for micturition. Many causes such as urinary tract infection, bladder outlet obstruction, and neuropathic bladder can influence bladder wall thickness (BWT).This study was designed to determine normal BWT in Iranian children. Materials and Methods: This was a cross-sectional study done in Isfahan in 2012 comprising 82 children aged 2-14 years without any urinary complaint. We measured thickness of posterior and lateral walls of the bladder in all children. Mean bladder wall thickness (MBWT) and mean bladder volume (BV) were also calculated. Results: In this study, we included 82 children (40 boys and 42 girls). Patients' mean age was 6.43 ± 2.89 years, mean weight was 21.32 ± 8.40 kg, mean height was 111.57 ± 20.51 cm, and mean Body Mass Index was 17.12 ± 4.93. Mean lateral bladder wall thickness (LBWT) was 1.75 ± 0.32 mm and mean posterior bladder wall thickness (PBWT) was 1.59 ± 0.34 mm. Mean BV was 111.65 ± 72.11 ml and MBWT was 1.67 ± 0.28 mm. BVW all Index (BVWI) was 1249.05 ± 701.67. Conclusions: LBWT was1.75 ± 0.32 mm and PBWT was 1.59 ± 0.34 mm.

Background: Postoperative pain is one of the most common complaints after elective laparoscopic cholecystectomy. The present study was aimed to evaluate the effect of paravertebral block using bupivacaine with/without fentanyl on postoperative pain and complications after laparoscopic cholecystectomy. Materials and Methods: This study was done on 90 patients scheduled to undergo elective laparoscopic cholecystectomy. Patients were assessed in two groups: The case group received bupivacaine and fentanyl, and the control group received bupivacaine and normal saline. Primary outcomes were severity of postoperative pain at rest and during coughing. Secondary outcomes were postoperative cumulative morphine consumption and the incidence of side-effects. Results: Pain score at rest before surgery, after recovery, hour-1 and hour-6 was not significantly different between the groups. But in hour-24 cases, the pain score during coughing was significantly higher than controls. Severity of pain at rest in time points was not different between groups. The frequencies (%) of moderate pain at mentioned times in case and control groups were 64, 31, 16, 9, 0 versus 67, 16, 7, 4, and 0, respectively. Pain score during coughing was lower in controls at hour-24 in comparison with cases, but in other time points was not significant. The control group significantly received more total dose of morphine in comparison with cases group. Nausea, vomiting and hypotension were similar in groups, but pruritus was significantly different between the groups. Conclusion: Adding fentanyl to bupivacaine in paravertebral block did not significantly improve the postoperative pain and complications after laparoscopic cholecystectomy. However, further studies are needed to be done.

Background: Myocardial blush grade (MBG), thrombolysis in myocardial infarction (TIMI) and corrected TIMI frame count (cT F C) are indices of successful angiographic reperfusion. This study sought to determine the predictors of angiographically successful reperfusion including demographic, clinical and angiographic factors in patients with ST elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). Materials and Methods: A cross-sectional study of patients with a confirmed diagnosis of STEMI undergoing pPCI was designed. Eligible patients referring to a university heart center were enrolled in the study from March 2012 to December 2012. Successful epicardial reperfusion was defned as TIMI flow grade 3 or cTFC<= 28 frames and successful myocardial reperfusion as MBG 2 or 3. Results: The study population consisted of 100 patients, including 74 males and 26 females, with mean ± standard deviation age of 58.27 ± 11.60 years. Achieving open microvasculature (MBG 2/3) was positively associated with a history of nitrate intake (P = 0.03) and history of calcium channel blocker (CCB) intake (P = 0.005). Hyperglycemia was inversely associated with achieving a final cTFC ≤ 28 frames (r = −0.32, P = 0.001). Conclusions: Our findings suggest that patients with a history of nitrate and CCB intake had a higher likelihood of successful PCI. In addition, patients with a higher blood glucose level on admission may have a reduced rate of reperfusion success. Future studies with a larger sample size are recommended to investigate the significant relationships observed in this study.

Background: 1,2 ICSRA, introduced by Aidembery et al., is a well-established technique, with up to 100% union rate among different studies . The purpose of our study was to evaluate the outcome of scaphoid nonunion undergoing 1,2 ICSRA bone graft in Iran. Materials and Methods: All participants who presented sequentially over a period of 24 months between 2010 and 2013 with nonunion scaphoid fracture with AVN in proximal pole were included in the study. Anteroposterior and lateral view plain radiographs of carpal bones were obtained for diagnosis of nonunion, and a diagnosis of avascular necrosis was made by MRI of the scaphoid. Subjects underwent 1,2 ICSRA bone graft surgery. Patients were assessed based on radiographs and the Mayo Wrist Score (MWS) questionnaire on before and after surgery. Data were analyzed using SPSS ver. 18 by paired t test. Results: Overall, 16 patients (100% male) were included in the study. Mean age of subjects was 27.50 ± 5.86 (18 to 38). Mean Mayo score was 36.63 ± 8.92 and 83.75 ± 9.22 before and 6 month after surgery, respectively, and the difference was statistically significant (P < 0.001). after 8 weeks, 10 (62.5%) had union, and after 12 weeks, all subjects had union. Nine (56.25%) of our patients had excellent functional outcome, 5 (31.25%) had good and 2 (12.5%) had satisfactory functional outcome. Conclusion: 1,2 ICSRA is a proper pedicle of vascularized bone graft due to the ease of visibility and dissection. The functional results and union rates were satisfactory in our study.

Background: No ideal treatment has been established for Striae distensae (SD), particularly in the late phase (Striae Alba (SA)) .Various types of lasers have been recently proposed as treatment options for SD. This study aims to compare the clinical efficacy of a fractional CO2 laser as well as a combination of fractional CO2 laser and Pulsed dye Laser (PDL) in the treatment of SA. Materials and Methods: Eighty-eight SA lesions in three female patients were included. Lesions on each half of the body were randomly enrolled in each group. Group 1 (n = 44) were treated by Fractional CO2 laser resurfacing and group 2 (n = 44) by a combination of PDL and Fractional CO2 laser, alternately. Digital Photographs were taken and the surface area of each lesion was measured digitally (using the PictZar Digital Planimetry Software) at the baseline and four weeks after treatment. The clinical improvement was assessed by comparison of the pre- and post-treatment photos and the participants' views about their degree of improvement, using a 10-point verbal analog scale (VAS). Results: The mean surface area decreased significantly in both groups after treatment. The mean difference between the pre- and post-treatment surface area was 0.62 ± 053 for group 2 and 0.41 ± 0.43 for group 1 (P-value = 0.03). Mean VAS and dermatologist assessed improvement scale in group 2 (6.68 ± 0.77 and 2.2 ± 0.76 respectively) were significantly higher than those in group 1 (5.45 ± 0.90 and 1.8 ±0.72 respectively, P-value <0.001 and 0.04 respectively). Conclusion: The combination of PDL and fractional CO2 laser was more effective than fractional CO2 laser alone and could be suggested as a clinical option in the treatment of SA.

Background: The aim of this study was to examine the effects of preoperatively administered i.v. hypertonic saline on hypotension following induction of general anesthesia. Materials and Methods: Fifty-four patients who scheduled for elective surgery were randomly allocated to two groups of 27 patients who received hypertonic saline 5% (2.3 ml/kg) or received normal saline (13 ml/kg). Infusion of hypertonic saline was done half an hour before induction of anesthesia during 30 minutes. Anesthesia was conducted in a standard protocol for all patients. Age, sex, body mass index (BMI), systolic and diastolic blood pressure (SBP, DBP), heart rate (HR) and mean arterial pressure (MAP) were assessed in all patients. Results: The mean age of patients was 36.68 ± 10.8 years. Forty percent of patients were male. The mean SBP at min 2 and min 5, mean of DBP at min 2, 5, and 15, mean of HR at all time points and mean of MAP at min 2 and 15 between groups were no significantly different (P > 0.05), but mean of SBP at min 10 and 15, mean of DBP at min 10, and mean of MAP at min 5 and 10 in hypertonic saline group was significantly more than the normal group (P < 0.05). Trend of SBP, DBP, HR and MAP between groups were not significantly different (P > 0.05). Conclusions: Infusion of hypertonic saline 5% (2.3 mg/kg) before the general anesthesia led to a useful reduction in MAP and reduced heart rate, with no episodes of severe hypotension.
