Abstract
DNA typing is a new method with important applications in forensic medicine. In the present study, we evaluated application of DNA typing in Iran. Loci Hum LPL, Hum Tpox, Hum F13, Hum vw 31A, Hum TH01 and Hum FES/FPS of DNA short tandem repeats were studied. To determine sensitivity of the test, 85 mother-child couples (1020 chromosomes) that were referred to DNA section of legal medicine organization of Iran were included and for determination of it's specificity 42 brother-sister couples (1200 chromosomes) and 58 non-relative couples were examined. The results show lack of mutations in the studied loci and acceptable sensitivity of the test. Of 12 alleles of siblings, there were 2-6 differences, in contrast with 3-9 differences in non-relatives, so the test has 100% specificity in these loci. Considering polymorphism, power of exclusion of these 6 sites was 99%.

Abstract
Introduction: Thyroid diseases are one of the most common endocrine diseases. Incidence of thyroid diseases in women is ten times more than men. Menstrual irregularities and fertility is occasionally the first sign of thyroid diseases.
Materials and methods: In a prospective study, 325 thyroid patients were evaluated in Emam hospital. Incidence and type of menstrual irregularities were evaluated in these patients.
Results: 55.8 percent of hypothyroid patients had normal pattern ob bleeding. 44.2 hyper thyroid patients had menstrual irregularities which were in the form of oligomenorrhea and 41.7 percents of hypo-thyroid patients were irregular in the form of polymenorrhea, oligomenorrhea and menorrhagia.
Conclusion: In these patients, menstrual irregularities cured by treatment of thyroid diseases and reduced surgical interventions.

Abstract
Background: Pulmonary involvement is a common and serious complication of rheumatoid arthritis. This cross sectional study sought to determine the prevalence of pulmonary disease in patients with rheumatoid arthritis on the basis of history, physical examination, chest X-ray and PFT.
Materials and Methods: 103 patients (81 Women, 22 Men) fulfilling the ACR (American College of Rheumatology) criteria for RA (Rheumatoid arthritis) were consecutively included in a cross sectional study. Detailed medical (including respiratory symptoms and the disease activity symptoms) and drug and occupational histories and smoking were obtained. All patients underwent a complete pulmonary and rheumatologic examination and conventional chest radiography. All patients underwent PFT that comprised spirometry and body plethysmography.Results for PFTs were expressed as percentage of predicted values for each individual adjusted for age, sex, and height.
Results: On the basis of history: Their mean age was 43.3 ± 2.6 years (range: 17-74) and the mean duration of the disease was 69.3 ± 15.6 months. Rheumatoid factor was positive in% 61.2. No patients were 0.5Pack/Year smoker in whole life. Prevalence of pulmonary involvement based on radiographic and pulmonary function test detected in 41 patients (39/7%). The most frequent respiratory clinical finding was dyspnea (33%), (NYHA grade I in 17.5% and NYHA grade II in 15.5%), Cough (with or without sputum) in 13.6 %, Crackle was the most sign in pulmonary examination (5.8%). Chest X-ray was abnormal in 13.3 % that the most common finding in this study was reticulonodular pattern in 20 patients (19.4 %), and pleural effusion detected in 7 patients (6.7%). PFT was abnormal in 30 patients (29.1 %). A significant decrease of FEF 25%-75% below 1.64 SD. Small airway involvements was the most abnormal finding of PFT. No relation between rheumatoid arthritis disease activity (ESR>30, Morning stiffness>30', Anemia, thrombocytosis) with pulmonary disease was seen.
Conclusion: This study suggests a high prevalence of lung involvement in patients with rheumatoid arthritis.Therefore we recommend a complete investigation in patients with RA with any respiratory symptom.

Abstract
Background: Fibromyalgia has been defined as a constellation of complaints including diffuse chronic pain and the presence of tender points. Its frequency varies from 3% to 20%. This study was conducted to estimate the prevalence of fibromyalgia syndrome in patients who come to the general medical clinic of Dr. Shariati hospital.
Methods: Using a standard questionnaire, all patients who came to the general medical clinic were asked about their ages, presence of diffuse chronic pain, marital status, educational level, living place, number of children and presence of fatigue or sleep disorder by a physician, without any gender or age restriction and without considering their main complaints or their underground diseases. The same physician did a thorough physical examination with special attention to the tender points in order to diagnose fibromyalgia according to the ACR criteria. To rule out other differential diagnosis relevant tests would be ordered for suspected patients.
Results: Among 1004 patients who were assessed, the prevalence of diffuse chronic pain was 14.6% (95%CI: 12.4-16.8). Forty patients 4% (95%CI: 2.9-5.2) suffered from fibromyalgia syndrome, their mean age (±SD) was (48.4±14.9) years.92.5% of these cases were female and 7.5% (3 patients) were male.The prevalence of fibromyalgia among women was 5.98% (95% CI: 4.31-8.06) and among men was 0.78% (95% CI: 0.20- 2.11) (OR=8.1,95%CI:2.48-26.44). There was a meaningful statistical relation between the prevalence of fibromyalgia and gender (P=0.001). There was also a direct statistical relation between the prevalence of fibromyalgia and low educational level (P=0.003). But there was not any relation between fibromyalgia and living place or marital status.Also, there was no relationship between the prevalence of fibromyalgia and having more children (Logestic analysis).82.5% of patients with fibromyalgia suffered from sleep disorders and 92.5% of them complained of fatigue. There was remarkable statistical relations between fibromyalgia syndrome and sleep disorders or fatigue. (P<0.001)
Conclusion: Fibromyalgia syndrome is relatively prevalent among Iranian and in some extents its epidemiological aspects are comparable to those in developed countries. More extensive epidemiologic studies on fibromyalgia is recommended in general population

Abstract
Background: Laparoscopic cholecystectomy is a minimally invasive procedure whereby the gallbladder is removed using laparoscopic techniques. Monopolar electerosurgical energy is the method of dissection of gallbladder from liver bed. Ultrasonic energy causes less thermal damage and suggests an alternative to monopolar elevterocautery. Leptin is a tissue factor and C-reactive protein (CRP) is an acute phase protein that builds up in surgical damages. In laparoscopy, pneumoperitoneum and thermal damage cause this increase. In this study, after completion of surgery with both methods, plasma leptin and CPR were measured. Next, the complications and benefits of the two methods were compared.
Methods: This single blind randomized clinical trial was conducted on 78 patients who were candidate for laparoscopic cholecystectomy in surgery clinic of Razi Teaching Hospital in Ahvaz Jundishapur University of Medical Sciences from March 2013 to March 2015. Patients were divided randomly into two groups of ultrasonic and electerocautery. Then, leptin’s level and CRP’s level were measured at completion of surgery, 30 minutes after completion, 6 and 24 hours after completion of surgery in the two groups.
Results: This study shows that the average rate of leptin at completion of surgery, 30 minutes after completion, 6 and 24 hours after completion of surgery in ultrasonic group had less increase than electerocautery group and the difference was statistically significant (P= 0.0001). The average rate of CRP at completion of surgery, 30 minutes after completion, 6 and 24 hours after completion of surgery in ultrasonic group had less increase than electerocautery group and the difference was statistically significant (P= 0.0001).
Conclusion: The level of leptin and CRP shows that surgery with ultrasonic method will provoke the immune system less than electerocautery method.

Abstract
Background: Looking at the increased incidence of recurrent vulvovaginal candidiasis and refractory resulting from such non-albicans Candida species in recent decades, this study was performed aiming the use of rapid biochemical and molecular detection of drug-resistant Candida species in response to fluconazole in patients with vulvovaginal candidiasis and recurrent vulvovaginal candidiasis.
Methods: The cross-sectional study was performed at Kowsar Gynecology Center, Motahhari educational hospital and Medical Mycology Center, Faculty of Medicine, Urmia, Iran, from October 2013 to July 2015. Those patients referred to the clinic with symptoms of vaginal discharge, itching or burning that swab samples from endo-exocervix and distal fornix discharge were taken. The vaginal discharge samples submitted to Medical Mycology Center, Urmia School of Medicine for the direct microscopic examination and cultures. Identification at the level of species was performed using CHROMagar Candida and Corn meal agar media. The molecular test polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) used for confirming culture results. For the susceptibility assay, disc diffusion method was performed with fluconazole and clotrimazole.
Results: In these study 198 samples collected from patients with symptoms of vulvovaginal candidiasis, 77 vulvovaginal candidiasis cases were identified. Candida species are common in primary and recurrent cases in terms of frequency, Candida albicans (85.7%), Candida krusei (10.2%) and Candida glabrata (4.1%) were identified respectively. Total of 27 cases of recurrent vulvovaginal candidiasis, 10 cases were resistant to both clotrimazole and fluconazole (37%) was observed that the most common species are resistant to treatment were Candida albicans by (82.1%), Candida krusei (14.3%) and Candida glabrata (3.6%) respectively. Drug resistance in Candida albicans, Candida krusei and Candida glabrata causing recurrent vulvovaginal candidiasis included 69.1%, 75% and 100% respectively.
Conclusion: Our findings have shown frequency of resistant non-albicans Candida species to fluconazole and clotrimazole is increasing. There is a considerable difference between Candida albicans and non-albicans species, Candida glabrata for the resistance to fluconazole and clotrimazole. |

Abstract
Background: Diabetes mellitus has several complications. The Late diagnosis of diabetes in people leads to the spread of complications. Therefore, this study has been done to determine the possibility of predicting diabetes type 2 by using data mining techniques.
Methods: This is a descriptive-analytic study that was conducted as a cross-sectional study. The study population included people referring to health centers in Mohammadieh City in Qazvin Province, Iran, from April to June 2015 for screening for diabetes. The 5-step CRISP method was used to implement this study. Data were collected from March 2015 to June 2015. In this study, 1055 persons with complete information were included in the study. Of these, 159 were healthy and 896 were diabetic. A total of 11 characteristics and risk factors were examined, including the age, sex, systolic and diastolic blood pressure, family history of diabetes, BMI, height, weight, waistline, hip circumference and diagnosis. The results obtained by support vector machine (SVM), decision tree (DT) and the k-nearest neighbors algorithm (k-NN) were compared with each other. Data was analyzed using MATLAB® software, version 3.2 (Mathworks Inc., Natick, MA, USA).
Results: Data analysis showed that in all criteria, the best results were obtained by decision tree with accuracy (0.96) and precision (0.89). The k-NN methods were followed by accuracy (0.96) and precision (0.83) and support vector machine with accuracy (0.94) and precision (0.85). Also, in this study, decision tree model obtained the highest degree of class accuracy for both diabetes classes and healthy in the analysis of confusion matrix.
Conclusion: Based on the results, the decision tree represents the best results in the class of test samples which can be recommended as a model for predicting diabetes type 2 using risk factor data.

Abstract
Background: Metabolic syndromes have been identified as a major risk factor for people with cardiovascular disease. Metabolic syndromes are defined as a range of conditions including waist-fat, abdominal obesity, high blood pressure, diabetes, high triglycerides, and HDL. Considering the importance of controlling metabolic syndrome, the research study subject with the mentioned aim is so important in the world and Iran. One of the affecting factors that have reported contradictory results in the previous study are shift work. Therefore, this prospective cohort study was conducted to investigate the relationship between metabolic shift syndromes on labor men.
Methods: This five-year prospective cohort study has been conducted in randomly selected workers (using random cluster sampling) who work in Esfahan’s Mobarakeh Steel Company (the largest steel company in Iran country that located in Mobarkeh city in Isfahan province, Iran) from April 2011 March 2015. In this study shiftwork and metabolic syndromes considered as an independent and dependent variable respectively. In addition, age, education and work experience considered as a controlling variable. In this study, routinely rotating (ROR) and weekly rotating (WRO) shifts were scheduled with a clockwise rotation plan (two mornings, two evenings, two night and two days off for ROR and three morning shifts, three evening shifts, and one day off every two weeks, Fridays always off for WRO shifts). The morning, evening, and night shifts began at 7 AM, 3 PM, and 11 PM, respectively. Day workers (DW) worked from 7 AM to 3 PM on weekdays and had Thursdays and Fridays off.
Results: The study sample included 1321 male workers (mean age=43). Among these subjects, 528 (40%), 155 (12%) and 638 (48%) were day workers, WRO shift workers, and ROR. The 5-year odds ratio (OR) of metabolic syndrome in the ROR shift worker compared to the DW was OR=1.93, P-value=0.044 and for a WRO shift with OR=1.26, P=0.64.
Conclusion: Considering the result of this study increased risk of metabolic syndrome in ROR shift worker rather than DW has been approved but such increase in WRO shift rather day worker had not to be approved.

Abstract
Background: Death is one of the serious consequences of burns, which usually occurs as a result of hospital infections. This study was conducted with the aim of investigating the existing disagreement regarding the admission of more than 90% patients in the burn intensive care unit with the isolation room of the burn unit.
Methods: This retrospective descriptive-analytical study was conducted based on case review. The statistical population included the files of patients hospitalized in the burn wards and burn intensive care unit of Zare'e Sari Burn and Psychiatric Center from 2011 to 2023 who died. All these patients were included in the study as a census. The data was extracted through a checklist prepared by the researcher. Descriptive and inferential analysis of the data was performed using SPSS version 21 software. The variables studied included gender, age, burn percentage, burn factor, and duration of hospitalization, and determining the relationship between burn percentage and survival time in the two burn intensive care units and the isolation room of the burn unit was the main variable. The mean and standard deviation were used to describe quantitative data, and the frequency and percentage were used to describe qualitative data.
|
Results: Among 882 cases, 226 patients had burns above 90%. 143 cases were related to men (63.3%). Most patients were in the age group of 19 to 40 years (61.9%). The cause of the burn (54.9%) was flame. Among the patients (83.2%) were hospitalized in the isolation room of the burn ward. Although the average days of hospitalization of patients above 90% in the burn intensive care unit was 13.71±11.82 days and the burn isolation room was 8.66±9.11 days, the Mann-Whitney test showed that the average survival time of these patients in the burn isolation room of the burn ward was significantly different from the intensive care unit. (sig.=0.001).
Conclusion: Although the average survival time in the two groups showed a significant difference, ultimately all patients in the two groups died within a few days of each other.
