Tehran University Medical Journal , 2012,
Abstract: Background: Oral metronidazole has been previously demonstrated to decrease postoperative pain after open hemorrhoidectomy. The aim of this study was to evaluate the effect of topical metronidazole in reducing postoperative pain of hemorrhoidectomy.Methods : In this double-blind, clinical trial forty 20- to 40-year old male patients were scheduled for hemorrhoidectomy under spinal anesthesia at the Imam Khomeini Hospital in Urmia, Iran from April to September 2010. The participants were assigned to receive topical metronidazole (n=20) or placebo (n=20). Pain intensity was assessed using a visual analog scale (VAS), the time of first narcotic request and morphine administrations were also recorded. Results : The VAS scores were lower in metronidazole than the control group but this difference was not statistically significant, except after 24 hr post-surgically. Morphine administration in the first 24 hr was lower in the metronidazole group (P<0.05).Conclusion: Although metronidazole could not prolong the time of first analgesic request, but application of metronidazole gel is associated with lower analgesic requirement.

Abstract: Introduction: Taking into account the importance of micronutrients in health and growth of the infants, the concentrations of zinc, copper, and iron in breast milk of mothers belonging to different economic classes and their effects on infants’ growth were investigated. Methods: Milk samples and information on personal characteristics, anthropometric and 24-hour food recall were collected from 90 lactating women belonging to 3 different socioeconomic classes who had exclusively breastfed their 90-120 day old infants. Concentrations of trace elements were analyzed using atomic absorption spectrophotometry and dietary information of subjects was analyzed by Nutritionist III software program. Statistical tests included Multiple Regression, ANOVA test and Independent t-test. Results: The mean zinc concentrations in mothers’ breast milk belonging to high, moderate and low socioeconomic groups were 1.6, 1.9 and 2.3 mg/l, respectively. Copper levels were 0.41, 0.47 and 0.85 mg/l, respectively and iron levels were 0.75, 0.8 and 0.9 mg/l, respectively. Group comparisons showed significant differences (P<0.05). Although association between mineral concentrations and WAZ or HAZ of infants was not significant, the WAZ of infants whose mothers' milk zinc concentration was more than 2 mg/l was significantly higher than WAZ of other infants (P<0.03). Despite no significant correlation between trace element intake and trace elements in milk, negative and significant correlations between maternal age and milk minerals concentrations were observed. Conclusion: The concentration of studied trace elements in milk of mothers with low economic status was higher but was not related to intakes and it was probably related to mothers' age. So, dietary consultations for older lactating mothers are needed.

Abstract: Relevance feedback (RF) approaches are use to improve the performance of content-based image retrieval (CBIR) systems. In this paper, a RF approach based on modification of similarity measure using particle swarm optimization (PSO) in a medical X-ray image retrieval system is proposed. In this algorithm, using PSO, the significance of each feature in the similarity measure is modified to image retrieval. This modification causes that good features have major effect in relevant image retrieval. The defined fitness function in PSO uses relevant and irrelevant retrieved images with different strategies, simultaneously. The relevant and irrelevant images are used to exhort and penalize similarity measure, respectively. To evaluate, the proposed RF is integrated to a CBIR system based on semantic classification. In this system, using merging scheme in a hierarchical structure, the overlapped classes are merged together and determined search space for each query image. The proposed RF evaluated on a database consisting of 10000 medical X-ray images of 57 classes. The proposed algorithm provides the improvement, effectiveness more than the literature.

Abstract: The ever-increasing number of logo (trademark) in official automation systems for information management, archiving and retrieval application has created greater demand for an automatic detection and recognition logo. In this paper, a classification hierarchical structure based on Bayesian classifier is proposed to logo detection and recognition. In this hierarchical structure, using two measures false accept and false reject, a novel and straightforward training scheme is presented to extract optimum parameters of the trained Bayesian classifier. In each level of the hierarchical structure, a separable feature set of shape and texture features is used to train and test classifier based on complexity of the logo pattern. The candidate regions for logo are extracted from document images by a wavelet-based segmentation algorithm, and then recognized in the proposed structure. The proposed structure is evaluated on a variety and vast database consisting of the document and non-document images with Persian and international logos. The obtained results show efficiency of the proposed structure in the real and operational conditions.

International Journal of Fertility & Sterility , 2012,
Abstract: Background: Polycystic ovary syndrome (PCOS) patients are more prone to abnormalproduction of some regulatory peptides. In these patients, studies on the serum levels ofleptin and ghrelin are controversial. This study aims to investigate serum levels of leptinand ghrelin and their correlation with metabolic and endocrine indices in PCOS.Materials and Methods: This case-control study was conducted on 60 women; 30 withPCOS and 30 healthy women whose age and body mass index (BMI) were matched and whowere referred to Alzahra Hospital, Tabriz, Iran. Serum levels of leptin, ghrelin, insulin, luteinizinghormone (LH), follicle stimulating hormone (FSH), sex hormone-binding globulin(SHBG), and testosterone were measured. The homeostasis model assessment of insulin resistance(HOMA-IR) was calculated. Descriptive statistics and correlations were performed usingSPSS 12.0 for Windows.Results: In PCOS women, serum levels of leptin, insulin, HOMA-IR, testosterone, LH,and LH/FSH were significantly higher, while SHBG was lower than in healthy women.Ghrelin and FSH were similar in both groups. Serum levels of leptin correlated with BMI(r=0.85, p<0.001), waist to hip ratio (WHR) (r=0.55, p<0.01), insulin levels (r=0.85,p<0.001) and HOMA-IR (r=0.67, p<0.01), while ghrelin levels had an inverse associationwith testosterone (r=-0.32, p=0.04).Conclusion: The results showed increased leptin levels while ghrelin remained unchangedin PCOS patients. In PCOS patients, leptin positively correlated with BMI,WHR, insulin, and insulin resistance, while ghrelin was only associated with serumtestosterone levels.

Abstract: Background: Disordered eating attitudes are contributing factors to the development of eatingdisorders. Adolescent girls are at high risk for eating diseases. In Iran, there is few data onthe subject, especially in Azarian adolescent girls, so we did this study for assessing disorderedeating attitudes and their correlates among Iranian Azarbaijani high school girls.Methods: In a cross-sectional study, 1887 high school girls were selected. Eating AttitudeTest-26 (EAT-26) and socio economical questionnaires were used. The EAT-26 score of 20or higher defined as disordered eating attitudes. Data were analyzed using the Statistical Programfor Social Sciences, by using from descriptive and analytical statistics.Results: Reliability and validity of the translated EAT-26 were 0.80, 0.76, respectively. Instudied subjects, mean (SD) of EAT-26 was 11.71(8.48). Totally, 16.7% (C.I with 95%: 15.1-18.3%) of students had disordered eating attitudes. About half of the participants were unhappywith their body weight and considered themselves as obese. Mean of EAT-26 washigher in this group. Groups, who intent to weight loss, were smoker, and who had age ofmenarche less than 11 years, also had higher EAT-26 scores. Parent’s literacy or job, birthorder, family size or income and house ownership had not any significant effect on EAT-26score.Conclusions: Persian version of EAT-26 has good reliability and validity for assessing disorderedeating attitudes in Azarian girl adolescents. Prevalence of disordered eating attitudesamong Azarian adolescent girls are in the range of some studies, but are less than Arabiancountries, and some European ones. In adolescent girls, body weight dissatisfaction, smokingand early menarche has important role in eating attitudes.

Abstract: Introduction: This study was conducted to assess the nutritional status in Iranian major depres-sive disorder patients. We also determined the relationship between nutrients intake with depres-sion severity.Methods: Seventy major depressive patients were selected randomly from outpatient depressive subjects, referred to Razi Psychiatry Hospital in Tabriz, Iran in 2007. Dietary intakes were rec-orded and compared with dietary reference intakes (DRIs). Definition of the disease and its se-verity were according to DSM-IV-TR and Hamilton Depression Rating Scale, respectively. Nu-tritionist III program, Chi-square, correlation and t-test were used for data analyses. Demo-graphic, clinical and laboratory data were analyzed using SPSS software for windows (ver-sion13.0).Results: According to dietary analysis, 11.4% and 55% of patients had dietary protein and energy deficiency, respectively. 97.1% and 95.7% of patients had less folate and B12 intakes than recom-mended dietary allowances. The mean (Mean ± SD) for plasma folate and B12 was 5.18±6.11 ng/ml and 389.05±346.9 pg/ml, respectively. Low plasma folate and B12 was observed in 51.4% and 50.0 % of patients, respectively. There was no significant relationship between blood folate and B12 levels with depression severity. Similarly, nutrients intake had no effect on depression se-verity.Conclusions: Low plasma concentrations and low dietary intakes of folate and B12 are common among Tabrizian depressive patients. It seems that nutritional intervention for increasing folate and vitamin B12 intake must be considered as health promotive and preventative program for pa-tients suffering from depression disorders.

Health Promotion Perspectives , 2011, DOI: 10.5681/hpp.2011.015
Abstract: Background: As breast milk micronutrients content are essential for health and growth of the infants, this study was conducted to determine the breast milk zinc, copper and iron concen-trations and their possible correlations with maternal nutritional status, dietary intakes as well as socioeconomic status.Methods: Breast milk samples and information on maternal anthropometric characteristics and dietary intake were collected from 90 Iranian lactating women with 3 different socioeco-nomic status who exclusively breastfed their infants. Concentrations of trace elements were analyzed using atomic absorption spectrophotometry. Nutritionist III program, Multiple Re-gression and ANOVA test were used for data analyses.Results: The mean milk zinc, copper, and iron concentrations were 1.93 ± 0.71, 0.58 ± 0.32, and 0.81 ± 0.2 mg/l, respectively. In all three SES groups only zinc mean level was lower than the recommended range. A significant difference was observed in breast milk zinc, copper and iron concentration between high and low SES groups (Zn (P<0.001), Cu (P<0.001) and Fe (P<0.044)) and also moderate and low SES groups (Zn (P<0.03), Cu (P<0.001) and Fe (P<0.049)). After adjusting for maternal body mass index (BMI), socioeconomic status, mean dietary energy, zinc, copper, and iron intakes, there was a negative and significant association between maternal age and breast milk zinc (β=-0.28, P<0.034), copper (β=-0.18, P<0.048), and iron (β=-0.22, P<0.04) concentrations.Conclusion: In low socioeconomic group with lower mean age, breast milk mineral levels were higher than others and there was no significant correlation between mineral levels and dietary intake. Hence it is supposed that maternal age may be better predictor of breast milk mineral levels.

Abstract: This study was planned to investigate the effects of supplementation of cinnamon on fasting blood glucose levels and lipid profiles among type2 diabetic patients. 60 subjects with type 2 diabetes from both sexes (30 males and 30 females) were allocated to the intervention and control groups (30 individuals per group). The doses of 1.5 g of cinnamon were equally administered orally in the form of cinnamon powder into 500 mg per capsule with breakfast, lunch, and dinner for 60 days. Control group received capsules of containing placebo. Blood samples were obtained on the beginning day of the experiment and at the end of 60 days. The fasting blood glucose levels and lipid profiles including total cholesterol, LDL-C, HDL-C and triglycerides of types 2 subjects were measured. Fasting blood glucose levels and lipid profiles in intervention group were significantly lower than control group (p<0.05). The average of fasting blood glucose levels, total cholesterol, cholesterol LDL and triglyceride levels were decreased after consumption of cinnamon powder, significantly(p<0.05). We observed no significant changes in fasting blood glucose levels and lipid profiles after consumption of placebo in control group. Conclusion: This study showed that consumption of cinnamon supplementation may be useful in control and decreasing of fasting blood glucose levels and lipid profiles among type 2 diabetes individuals.
