Abstract
Background: Cytotoxic lymphocyte antigen-4 (CTLA-4) plays an important role in regulating T cell activation. CTLA-4 gene polymorphisms are related with genetic susceptibility to various autoimmune diseases, including systemic lupus erythematosus (SLE). We analyzed the role of CTLA-4 polymorphisms at positions -318CT in patients who suffer from SLE.
Methods: This study was performed on 180 SLE patients referred to 5th Azar University Hospital in Gorgan, Iran. Three hundred and four ethnically-and age-matched healthy controls with no history of autoimmune diseases entered the study between 5th May 2008 and 23rd October 2009. DNA was extracted from blood samples according to the standard procedure. Polymerase chain reaction- restriction fragments length polymorphism (PCR-RFLP) was used to analyze the genotype and allele frequencies of this polymorphism. PCR was carried out using the following primers: forward 5′-AAATGAATTGGACTGGATGGT-3′ and reverse 5′-TTACGAGAAAGGAAGCCGT G-3′. The frequency of alleles and genotypes were assessed using direct counting. Chi-square test and Fisher’s exact test were used to compare the association between the alleles and genotype frequencies and SLE. P<0.05 were considered statistically significant.
Results: The CC genotype was observed in 94.5% of the SLE patients and 82.4% of the controls the difference was statistically significant (P=0.0001, OR=3.51, CI95%=1.77-7.53). The CT genotype, on the other hand, was more frequently observed in the control group (17.1% vs. 5.5%, P=0.0001, OR=0.28). T allele was significantly more common in the controls compared to SLE patients (P=0.0001, OR=0.26, CI95%=0.13-0.53).
Conclusion: Our results suggest that the -318C/T polymorphism of CTLA-4 gene might play a significant role in the genetic susceptibility to SLE. Therefore, further studies on populations, especially from other Middle East countries, are needed to confirm our results.

Abstract
Background: Polycystic ovary syndrome (PCOS) is a common complex condition. Evidences from studies on women with PCOS and rat PCO model suggest that the sympathetic regulatory drive to the ovary may be unbalanced (hyperactivity). Findings that support the involvement of sympathetic nervous system in the pathophysiology of PCOS are that the catecholaminergic nerve fibers in the polycystic ovaries of women with PCOS are denser than in normal ovaries. The purpose of this study was reduction of this hyperactivity.
Methods: This study was clinical trial and was performed in Reproductive Health Research Center, Tehran University of Medical Sciences, Iran, during January 2013 to 2015. A total of 61 women between aged 20-40 years and BMI under 28 kg/m2, who were previously diagnosed with PCOS were assessed. The diagnosis of PCOS was made according to joint criteria of the European Society of Human Reproduction and Embryology and the American Society of Reproductive Medicine (ESHRE/ASRM). The study objectives were explained to the patients before they entered the study, and an informed consent was obtained from all. They were divided into three groups as follows: (i) two study group (n=39) and (ii) control group (n=22). For evaluating effects of alpha-2 inhibitors (Clonidine and Yohimbine) by Eliza, the following variables were evaluated before and after drug therapy: serum cortisol adrenaline (A) noradrenalin (NA) beta-endorphin (&beta-End) insulin as well as sex hormones including FSH, LH and Estradiol.
Results: Our results showed that, Clonidine as central anti-adrenergic drug causes 61% of all pregnancies in the study group. This is high percentage of the pregnancy rate compared with yohimbine (P< 0.001). Yohimbine (Indol alkaloid) as alpha-2 adenoceptor antagonist increases follicular development in this disease. This follicle growth is higher than clonidine (P< 0.01).
Conclusion: Our findings showed that increasing the pregnancy rate and follicular development represent the strategic role of sympathetic nervous system (SNS) in polycystic ovary syndrome and) SNS may thus offer a novel biological and pharmacological target in treatment of PCOS.

Abstract
Background: Sacrococcygeal pilonidal disease (PD) is prevalent in the young adults. The cause of PD is unclear, and there are different surgical procedures for the treatment. The Pilonidal sinus disease is an unpleasant, chronic relapsing condition that is difficult to cure. There is a wide variety of surgical treatments with sub-optimal results for it. The ideal treatment for the pilonidal sinus disease has yet to be defined. There are many surgical approaches described in the literature. In this study, the long-term outcomes of four current surgical methods for PD were evaluated and compared. We aimed to assess recurrence, satisfaction, complications rate and wound healing time in the four current surgical methods for PD.
Methods: This cross-sectional study was conducted in the Department of Surgery at the Baqiyatallah University Hospital, Tehran, Iran, from April 2017 to September 2017. The study was carried out on 182 postoperative patients. Surgeries were performed in different methods such as; open, closed, semi-closed and limited excision. Diabetics, obese patients and patients with acute pilonidal abscess or prior PD surgery were excluded. All patients were followed for at least three years after surgery. During the follow -up period, patients were assessed for recurrence, satisfaction, complications rate and wound healing time. The outcomes were assessed by case notes analysis and follow-up telephone and postal questionnaires.
Results: In this study forty-four patients were operated via closed Method, 48 patients through open, 48 via semi-closed and 42 one's trough limited excision methods. The highest rate of recurrence was in the open group. There were no cases of recurrence in the closed group. There were also less postoperative hemorrhage and faster wound healing in the closed group. The average satisfaction of all patients was 88.9±8.7. The mean satisfaction rate in the closed group was 95.9±5.3 which was higher than other groups.
Conclusion: The results of this study demonstrated that in the non-recurrent cases of sacral pilonidal sinus, complete Excision and primary repair have fewer complications and shows higher satisfaction rate.

Abstract
Background: Polycystic ovary syndrome is the most common disorder in the endocrine system. Hyperandrogenism, hyperinsulinemia, chronic ovulation, and infertility are important Complications of PCOS. Health-related quality-of-life (HRQoL) has a significant reduction in women with polycystic ovary syndrome (PCOS). This reduction can be due to many disorders including: menstrual and sleep disorders, hirsutism, marital issues, infertility, and emotional/psychosocial problems. The purpose of current study was to investigate the role of sleeping and other environmental factors affecting the quality of life in patients with polycystic ovary syndrome.
Methods: This case/control study was conducted in 2017 in two groups: control and study (PCOS). The inclusion criteria were women aged 20-40 with a body mass index (BMI)<28. Exclusion criteria included no disease and no medication for all women. The participants were 180 women who were referred to the infertility center of Imam Khomeini Hospital in Tehran. Four questionnaires including Demographics (40 questions), sleep quality (PSQI) (19 items 0-3), quality of life (GHQ) (28 items) and psychometric (DASS-42) with their consent form were filled out. Student’s t-test and Chi-square were used to compare the variables between two groups and the Pearson correlation coefficient to examine the relationship between lifestyle dimensions.

Results: The mean weight and BMI (P=0.002), hirsutism and irregular menstruation cycle in the study group were greater than the control (P<0.001). In the study group the mean score of the sleep questionnaire in three dimensions: sleep problems (P=0.024), drug use (P=0.048), and the sufficiency of sleep (P=0.049) were higher than control.
Regression analysis showed that there is a significant relationship between quality of life and menstruation cycle (P=0.046), as well as the three dimensions of negative affecting situations with family income (respectively, 0.015, 0.016 and P=0.035).
Conclusion: The environmental factors can easily affect the quality of life in PCO women. Sleep patterns were not favorable, and the effect of menstruation on mood and low family income caused negative emotions in women with PCOS.
