Abstract
Background: Post-menopausal hemorrhage is one of the most common complains in gynecologic clinics. More than 60% of these cases have abnormal findings in diagnostic work ups. There is contraversy about the best diagnostic method for evaluating post-menopausal hemorrhage. The aim of this study was to evaluate the results of Trans-Vaginal Ultrasonography and compare its result to ones derived from direct endometrial biopsy and Hysteroscopy findings.
Methods: In a cross-sectional study, menopausal women who attended the outpatient clinic of Arash Hospital, Tehran University of medical Sciences, from April 2005 to March 2006 with the complain of hemorrhage were evaluated. In all of these patients, after getting informed consent, Trans-Vaginal Ultrasonography, Dilatation and Curettage and Hysteroscopy were performed.
Results: The total number of 90 women was recruited to the study with the age range of 41-80 years. The mean age of participants was 53.84 ± 6 years and 4.3 ± 5.1 years had passed from their menopause. The mean thickness of endometrium, measured by Trans Vaginal ultrasonography was 6.25 ± 3.7 millimeter. In the biopsy derived specimens, the most finding pathological presentation was atrophy (48.9%) and the Proliferative endometrium had the second prevalence (36.7%). Atrophy (44.4%) and Proliferative endometrium (33.3%) were the most prevalent finding in Hysteroscopy. There was a significant difference in endometrial thickness between groups of different pathological findings. A significant difference in endometrial thickness was also seen between groups with different Hysteroscopic finding. By grouping the data according to endometrial thickness, it became evident that endometrial thickness can predict the outcome of endometrial biopsy and Hysteroscopic finding efficiently. We used ROC curves to find the best grouping threshold for endometrial thickness to achieve the best sensitivity and specificity.
Conclusion: Measuring the endometrial thickness by Trans-Vaginal Ultrasonography is an appropriate non-invasive test for screening post-menopausal hemorrhage.

Abstract
Background: Exposure to low levels of lead increases blood pressure in humans and animals. Although there are controversial reports about the exact mechanisms of lead-induced hypertension, many factors such as alteration in the cardiovascular responsiveness to endogenous substances including catecholamines could be one of the mechanisms involved. In the present study, the effect of lead acetate on the systolic blood pressure and responsiveness to β-adrenergics was investigated in rats.
Methods: Through their drinking water, three groups of rats were exposed to 100 ppm lead acetate for periods of 4, 8 or 12 weeks. The blood pressures of the rats were monitored throughout the study. The rat hearts were isolated and perfused with Krebs-Henseleit solution (pH=7.4) at 37˚C and gassed with 95% O2 + 5% CO2. The heart rate (chronotropic) and contractile (inotropic) responses were recorded before and after adding isoproterenol at multiple concentrations to the perfusion solution.
Results: The mean blood pressures in the 8 and 12-week lead-treated groups were significantly higher than that of the control group (P<0.01). The chronotropic response to many doses of isoproterenol was significantly increased in the 12-week lead-treated group compared to that of the control group (P<0.05). The inotropic response to this drug was significantly increased in both the 8- and 12-week lead-treated rats (P<0.05 and P<0.01, respectively).
Conclusions: Our results indicate that low-levels of lead increase systolic blood pressure as well as both chronotropic and inotropic effects of β-adrenergics, which could imply an important role in the pathogenesis of lead-induced hypertension.

Background: Chlamydia
trachomatis is a common and curable STI that may be
symptomatic or asymptomatic. The few studies on C. trachomatis among Iranian women have
had, for the most part, small sample sizes and are therefore unsuitable for
epidemiological deductions. The aim of this study was to estimate the
prevalence of urogenital C. trachomatis infections by PCR on urine samples of married women in their
fertile years in order to determine the need for a C. trachomatis screening program for
asymptomatic women in Iran.
Methods: This descriptive-analytical and cross-sectional study
was performed on 991 married women. The research material consisted of
questionnaires and urine samples, which were transported daily to Avesina
Research Institute, Tehran,
Iran, to
extract their DNA and prepare them for PCR tests. The gathered data were
analyzed by SPSS, version 13, and evaluated statistically by t-test, chi-square
test, Fisher's exact test and logistic regression, considering p<0.05 as
significant.
Results: Of all the subjects, 127 (12.8%) were positive by PCR for C. trachomatis.
The mean age of the participants was 28.88±
6.19 years. Infection was more prevalent among
those with lower levels of education, who were employed and not pregnant. This
infection was more prevalent among those who were using contraception, especially
condoms. Reproductive history revealed that infection was more prevalent among
participants with a history of vaginal discharge, pelvic pain, infertility and
low birth-weight infants, and less prevalent among those with a history of abortion,
preterm delivery and ectopic pregnancy. However, these patterns were not statistically
significant.
Conclusion: In populations with C. trachomatis prevalences higher than 4%,
screening programs are recommended. Thus, Chlamydia screening should be part of the health care program in Iran to reduce the
burden of this disease.

Abstract
Background: Although nonoperative management is as an alternative method for surgery in the management of blunt splenic trauma, there are many contraversies in criteria for appropriate selection of the best method of management in patients. This study was conducted to find clinical and diagnostic criteria for selection of patients for surgery.
Methods: One hundred and one patients with blunt splenic injury entered in our prospective observational and cross sectional study. Patients with unstable hemodyna-mics and obvious abdominal symptoms underwent emergency splenectomy was performed. In stable patients, abdominal and pelvic CT scan with IV contrast was performed. Patients with stable hemodynamics who lack obvious abdominal symptoms, admitted in ICU ward. Patients' demographics, blood pressure changes, hemoglobin concertration, severity of trauma with injury severity score (ISS) scoring system, CT scan findings, amount of blood transfusion Hospitalization time and mechanism of injury were recorded.
Results: From 101 patients, 61(60.3%) underwent early laparotomy. 40 patients were planned for conservative management. In 30 patients (29.7%) nonoperative management was successful. In 10 patients (9.9%) This management failed and they underwent surgery. Hypotension, hemoglobin concentration dropping more than one episode and blood transfusion requirement more than one time, increased the risk of operation. Higher ISS number and ISS≥16 had a direct relation with operative management. In patients who underwent early laparotomy CT grade of injury was higher. CT findings correlated well with laparotomy findings.
Conclusion: Nonoperative management was successful in 75% of selected patients. With correct selection of patients and concerning to homodynamic status, hemoglobin concentration changes and injury severity score in conjunction with CT findings, we can use this management in greater number of patients.

Abstract
Background: Over the past 50 years, subtotal or supracervical hysterectomy has come to be viewed as a suboptimal procedure reserved for those rare instances in which when concern over blood loss or anatomic distortion dictates limiting the extent of dissection, the aim of this study was to compare total and subtotal laparoscopic hysterectomy.
Methods: The patients who were candidates for hysterectomy with benign disease, with no contraindication for laparoscopic surgery entered the study in Arash Hospital, from March 2007 to April 2009. By simple randomization 45 patients (25 for TLH and 20 for SLH) were selected. Demographic Details and intra and post operative complications, were recorded by the staff and were compared between two groups.
Results: The average time for TLH operations look significantly longer than SLH operation (148.6±29.7 minutes 128.5±25.64 minutes, p=0.03). Although, the hemoglobin (gr/dl) drop in TLH was significantly higher than SLH (1.54 Versus 0.9, p<0.05) Blood transfusion were common in SLH (1 case Versus 3 Cases). The total length of hospital stay, was significantly shorter after SLH than TLH (3.6±1.47 day and 2.85±0.59, p=0.04). The drug requirements to control pain during hospitalization after both surgeries with analgesic injection were not significantly different, but with suppositories analgesic in SLH more than TLH. The time of return to normal activity was reported (p<0.0001) significantly shorter after SLH than TLH (13.12±18.1 and 5.04±1.79, p=0.0001). Sexual function had no significant difference between two groups but dysparunia in SLH was significantly lower than TLH (p=0.02). Cyclic bleeding and cervical prolaps, was not reported in two groups. Finally intra and post operative complications were more frequent in TLH.
Conclusions: SLH is a safe and effective surgery. Our data suggest that SLH can replace TLH in selected cases.

Background: Neuroleptic
malignant syndrome is an idiosyncratic and potentially fatal reaction to
neuroleptic drugs and is characterized by fever, muscular rigidity, altered
mental status, autonomic dysfunction, elevated serum CPK and
leucocytosis Neuroleptic malignant syndrome is treated with dantrolene,
bromocriptin, amantadin and electroconvulsive therapy.
Case: A 22 years old,
schizophrenic female was refered to the Emergency ward of Roozbeh hospital in
Tehran, Iran in December 2008 with aggression, impulsivity, and reduced sleep.
After injection of haloperidol, the patient developed a high grade fever,
diaphoresis and muscular stiffness. She was diagnosed as neuroleptic malignant
syndrome and the treatment with dantrolen, bromocriptin and amantadin
initiated. Although fever subsided, other signs continued, therefore we applied
electroconvulsive therapy to this case.
Conclusion: Due to excellent response of the patient to electroconvulsive
therapy and the rare reports of electroconvulsive therapy in neuroleptic
malignant syndrome in the
Iranian population, this case may lead to develop studies for further
investigations of this issue.

Abstract
Background: Botulinum
toxin (Dysport) is a powerful semi-biological toxin. It has proved to be a
remarkable therapeutic agent for treatment of benign anal disorders. Different
results have been achieved from injection of botulinum toxin in order to
treatment of anal fissure since 1993. The aim of this study was to evaluate the efficacy of
botulinum toxin injection in the treatment of chronic anal fissure Comparing
with lateral internal anal sphincterotomy (LIS).
Methods: 36 patients
entered into two groups, Dysport injection and Lateral Internal Sphincterotomy,
randomly. Dysport group were treated by injection of 50 units of
botulinum toxin, 25 units of drugs in each side, and LIS was done in
surgery group by open method in left side. Pain, recovery and incontinency were
compared between two groups during six months of follow up.
Results: Based on this study,
treatment of anal fissure does not affected by age and gender. Regarding to
location of fissure, there was no difference between two different genders. Mean of age and ratio of gender were similar in both
groups. The severity of pain in surgery group was lower than Dysport group six
months after treatment (0.4±0.7 and 3.2±2.6 respectively, p<0.001). Recovery ratio in surgery group was higher than Dysport after six
months (95% Vs. 44.4% p<0.001). Gas or fecal incontinency did not reported after
six months in both groups.
Conclusion: Botulinum toxin is not efficacious in patients
with chronic anal fissure, comparing with LIS. More future studies are necessary for final judgement.

Abstract
Background: Chlamydia trachomatis is the most common bacterial sexually transmitted infection in the world, but the effect of this infection on male fertility is still controversial. Despite reports of interaction between Mycoplasma genitalium and sperm, this pathogen in semen samples of infertile men is less studied. We studied, the prevalence of Chlamydia trachomatis and Mycoplasma genitalium infection in infertile men.
Methods: Among attending Avicenna Infertility Center, 120 men who had abnormal semen analysis tests were selected and the samples were taken. After detailed analysis of semen quality, DNA was extracted from each sample by chelex. Samples were evaluated for these two pathogens by multiplex PCR. Results were statistically analyzed.
Results: Chlamydia trachomatis and Mycoplasma genitalium was detected in 23/3% and 12/5% of the samples, respectively. Although, Mycoplasma genitalium infection rises by increasing (P=0.640) and decreasing in age of first sexually activity (P=0.203), and also positive cases of Chlamydia trachomatis infection showed increase regarding age increase (P=0.619) and age decrease in first sexually activity (P=0.511), but these differences were not statistically significant.
Conclusion: All in all, regarding to the increased prevalence of Chlamydia trachomatis infection compared with the only similar study in Iran and high prevalence of Mycoplasma genitalium infection in infertile men, this assessment was done. A multiplex PCR protocol rapidly and simultaneously identify these organisms in comparison with uniplex from clinical samples. Based on our results screening for Chlamydia trachomatis and Mycoplasma genitalium infection among infertile men seems to be valuable.

Abstract
Background: Meningitis is one of the serious and dangerous infections in the infancy and childhood and rapid diagnosis of meningococcal disease is important, especially in infants. C-reactive protein (CRP) is a protein found in blood and is an acute phase protein. CRP sensitive reactive that used for diagnosis of infection. This study conducted to assessment of the relationship between cerebrospinal fluid C-reactive protein, and neonatal meningitis, as well as diagnostic value of test.
Methods: Forty nine hospitalized infant that suspected to meningitis were enrolled in this analytic cross sectional research via non probable accessible sampling. 28 patients (52.7%) of all the patients were male and 21 patients (42.8%) were female. The average age of the patients was 22.6±11.88 days. Data from clinical examinations and laboratory tests entered in a questionnaire and all of samples divided in two bacterial (septic) and non-bactria (aseptic) meningitis group. All data including cerebrospinal fluid CRP of newborns were statistically analyzed.
Results: In total, the mean and standard deviation of age was 22.6±11.88 days. 57.2% of infants were male and 42.8% were female. In total, 40.82% of infants were diagnosed with septic meningitis. There was no significant difference between septic and aseptic groups in terms of sex (P= 1.00) also in terms of age (P= 0.1). The mean and standard deviation of CRP level in septic meningitis group was 0.95±0.68 mg/L and in aseptic group was 0.16±0.36 mg/L. The CRP level difference in septic meningitis group compare with aseptic group was statistically significant (P<0.000). The finding showed that cut off point for CRP level as a diagnostic test was 0.17 mg/L, sensitivity was 95% and specificity was 86%.
Conclusion: In the present study, newborns with septic meningitis had higher cerebrospinal fluid CRP level than newborns with aseptic meningitis, and CSF-CRP can be used in rapid diagnosis of septic and aseptic meningitis. Although this result has been seen in many studies, but more research is needed.

Abstract
Background: Severity of respiratory infection in children is depended on various fac-tors such as causative organism and the host immunologic response to the organism. Vitamins and micronutrients play an important role in this response with supporting the immune system and therefore, the response to infections. Nutritional deprivations in children, especially vitamins and micronutrients such as zinc, vitamin A and vitamin D are very common in middle east and other countries in Asia, which is due to inappro-priate diet and nutrient loss in recurrent infections. This study aimed to evaluate the se-rum levels of vitamins A, D and zinc in hospitalized children aged six months to five years.
Methods: This analytic cross-sectional study was performed in 65 children aged six months to five years who were hospitalized in pediatric and surgical wards of Rasul Akram Hospital and Bahrami Hospital in Tehran. All of samples were evaluated ac-cording to WHO cri-teria for acute respiratory infection, and underwent measurement of serum vitamin A, vitamin D and zinc levels by using Atomic, Elisa and spectropho-tometer methods.
Results: Serum levels of vitamins A in patients with acute respiratory infection was 0.27±0.16 µg/ml and in children without infection was 0.41±0.2 µg/ml, that different wasn’t statistically significant (P=0.4). Serum levels of vitamins D in patients with acute respiratory infection was 35.37±34.68 ng/ml and in children without infection was 45.78±21.05 ng/ml, that different wasn’t statistically significant (P=0.1). Serum levels of zinc in patients with acute respiratory infection was 87.93±23.34 µg/dl and in chil-dren without infection was 106.95±23.70 µg/dl, the difference was statistically signifi-cant (P=0.002).
Conclusion: According to finding in this trial, there is a correlation between lower levels of zinc in serum, and chance of respiratory tract infection in children. Future larger studies could provide the correlation between serum levels of vitamins A & D and chance of respiratory tract infection.

Abstract
Background: Toxic shock syndrome (TSS), a dangerous consequence of Toxic shock syndrome toxin-1 (TSST-1) caused by Staphylococcus aureus. The early detection for infections of Staphylococcus aureus in burned children is very important, also the pre-vention for consequences of TSST-1. Fever is one of the most noticeable sign in burned children. On the other hand, fever is one of the important consequences of TSST-1 pro-duction.
Methods: This study aimed to assess the toxic shock syndrome toxin-1 level in the wound’s specimens of two groups febrile and afebrile in the hospitalized burned chil-dren in Motahari hospital Tehran, Iran in the year 2013. In this case-control study, 90 children who admitted to the burn unit, divided in two groups of 45 patients: febrile (cases group) and afebrile (control group). All of burned children under went wound biopsy, and then all of wound’s specimens were tested by PCR for specific primer of toxin producing genome. Finally all of data collected and statistically analyzed. This data include group febrile and afebrile, demographic characteristics, percentage of burned surface severity and result of PCR.
Results: The positive result for PCR test, production of TSST-1 in febrile burned chil-dren (cases group) was 37.7% and in afebrile burned children (control group) was 11.1% that this different was statistically significant (P=0.003). The mean and stan-dard deviation for percentage of burned surface (severity) in samples with positive re-sult for PCR test was 30.9±16.93 and in samples with negative result for PCR test was 20.09±11.02 that this different was statistically significant (P=0.01). There was no dif-ference between positive PCR result and negative PCR result of age and sex.
Conclusion: Direct association was approved between the production of TSST-1 and the occurrence of fever in burned children. Increased surface severity of burns also re-lated to the production of TSST-1. Further research is recommended.

Abstract
Background: Assessment of the serum lead’s concentration in the newborn immediately after birth can be effective for the detection of lead poisoning in the early stages and prevent of developmental disorders and neuropsychiatric behaviors. This study aimed to assess the serum lead levels of cord blood in some of the hospitalized newborns.
Methods: This cross-sectional analytic study conducted in the newborns ward of two hospitals (Rasoul Akram and Akbar Abadi) From December 2011 to October 2012 in Tehran, Iran. After non-probability sampling, 60 newborns in the first days after birth, underwent the cord blood sampling and the cord blood lead levels were measured by atomic absorption spectrophotometer. Then all of data were collected and analyzed. The serum lead concentration greater than 5 μg/dl was considered valuable.
Results: In total, 61.4% of samples were boys. The mean (±SD) of gestational age was 37.4±2.64 weeks and mean (±SD) of birth weight was 2701±642.8g. The mean (±SD) of maternal age was 29.20±6.73 years. 70% of mothers were urban. 13% of mothers had a history of drug use, and 5% were current smokers. The mean (±SD) of the serum lead level of cord blood was 2.97±2.24 μg/dl. This level was not associated with fetal gender, place of residence, drug history and current smoking. This level in the 16.7% of samples was greater than 5 μg/dl (high risk cases). High risk level was associated with maternal age, weight and fetal age (P=0.02, P=0.004, P=0.03), but this level was not associated with fetal gender, place of residence, drug history and current smoking.
Conclusion: Serum lead level of cord blood was relatively higher than other studies, although the prevalence of the high risk newborns (serum blood lead levels greater than 5 μg/dl) was low. Further research has recommended assessing the serum lead level in other newborns in the different areas to identify risk factors of neuromotor outcome in infants to prevent.

Abstract
Background: In Nov 2013, the instruction for controlling high cholesterol has been released by the American College of Cardiology (ACC) and the American Heart Association (AHA) which need to be assessed in the different communities.
Methods: Of total 6275 individual aged 40-75 years who entered at the Tehran Lipids and Glucose Study from March 1999 to 20 March 2010 in first examination cycle, 5153 with the median follow-up of more than ten years were eligible to enter in this study. The 10-year risk of hard cardiovascular disease (Hard CVD) for Statin therapy based on ACC/AHA clinical guideline was calculated and this risk was calculated for each subgroup of the guideline who recommended for statin therapy comparing to the risk in individuals with prevalent CVD.
Results: Of nearly 6.5 million urban population of Iran (according to the 1996 census) about 4 million individuals (2.55 million men and 1.4 million women) were eligible for statin therapy. With respect to the urban population growth from the 1996 to the 2011 census (about 2.5 percent increases) the number of individuals for receiving statin increased by 50% (5 million men and 3 million women). Also, the risk in non-diabetic men with calculated risk of 5-7.5% and diabetic women with calculated risk of <5% for hard CVD was lower than 0.2. By removing these people from total eligible population, the burden of statin therapy will reduced about 8% which is about 540.752 persons, according to the Census 1996 and 1.155.079 individuals based on the census 2011.
Conclusion: The new guideline of ACC/AHA for statin therapy is relatively reasonable except for some subgroups. To reduce the burden of medical expenses, statin prescription can be ignored by physicians in these subgroups. Of course further research is required to calculate the net benefit for estimating the clinical usefulness of statin therapy in recommended guideline subgroups.

Abstract
Background: Cerebrospinal Fluid (CSF) culture for distinction between aseptic and bacterial meningitis can be difficult and long-term, and other diagnostic methods are under studying. This study aimed to assess the diagnostic value for the levels of Interleukin 1 (IL-1), IL-6 and IL-8 of CSF in the children and adolescent with meningitis.
Methods: Fifty-one patient with meningitis between one month and 18 year included in a Cross-Sectional Studies in the Rasul Hospital, Tehran, from 2012 to 2014. All of samples underwent aspiration of CSF. The routine tests performed that include culture coloring and biochemical of CSF. The concentrations of IL-1, IL-6 and IL-8 were determined by Enzyme-linked immunosorbant assay (ELISA) method and all of data were analyzed.
Results: Frequency of bacterial and aseptic meningitis was equal (49%). 64.7% of samples were boys and gender had not different between two bacterial and aseptic group (P=0.7). Mean (±SD) of the age in total was 358.46±858.40, and bacterial group had a higher mean of age than aseptic group (P=0.047). The level of IL-1 was 10.87±37.04 pg/ml in bacterial and 0.55±1.64 pg/ml in aseptic group, that had not different (P=0.168). The level of IL-6 was 90.51±139.3 pg/ml in bacterial and 21.36±67.84 pg/ml in aseptic group, that had significant different (P=0.030). The level of IL-8 was 365.40±765.52 pg/ml in bacterial and 50.66±59.34 pg/ml in aseptic group, that had significant different (P=0.047). Diagnostic value of IL-1 was noted in the 80.77% of bacterial and 68.00% of aseptic group that had not different (P=0.349). Diagnostic value of IL-6 was noted in the 53.85% of bacterial and 64.00% of aseptic group that had not different (P=0.572). Diagnostic value of IL-8 was noted in the 80.77% of bacterial and 28.00% of aseptic group that had significant different (P=0.000). There was not different between two group of CSF variables include coloring degree, WBC and RBC index, glucose and protein.
Conclusion: Although the concentration of IL-6 and IL-8 was higher in bacterial meningitis than in aseptic patients, only IL-8 had suitable diagnostic value for distinction between different types of meningitis.

Abstract
Background: Helicobacter pylori (H. pylori) cause various diseases especially gastrointestinal disorders. Clinical diagnosis of H. pylori infection can be done in different ways, and new diagnostic methods are under study .This study aimed to assess the levels of interleukin (IL) 6, 17 and 23 in the middle ear effusion of patients with otitis media, and the association between these levels with H. pylori infection.
Methods: This cross-sectional study conducted in 40 patients who nominated for ventilation tube (VT) placement due to otitis media with effusion, and admitted to ear, nose, and throat (ENT) clinics of Tehran University of Medical Sciences from March 2012 to August 2013. All of patients underwent myringotomy with VT insertion, and then aspirated effusion sample was tested. H. pylori infection diagnosed by polymerase chain reaction (PCR) and bacterial culture. The concentration of IL-6, IL-17 and IL-23 measured by enzyme-linked immunosorbent assay (ELISA). The levels of each interleukins were compared between the two positive and negative PCR groups.
Results: In all of samples, PCR test result was positive in 22.5%. The mean and standard deviation of IL-6 level was 10.11±2.95, IL-17 was 5.89±0.91 and IL-23 was 4.07±1.34. The mean±standard deviation (SD) of IL-6 level in patients with a positive PCR (H. pylori) was 22.29±6.40 and in patients with a negative PCR was 6.16±3.88 that difference was significant (P=0.01). The mean±SD of IL-17 level in patients with a positive PCR was 6.16±1.29 and in patients with a negative PCR was 5.81±1.13 that difference was not significant (P=0.42). The mean±SD of IL-23 level in patients with a positive PCR was 6.15±3.77 and in patients with a negative PCR was 3.42±1.33 that difference was not significant (P=0.27).
Conclusion: According to finding, association between H. pylori infection and increased levels of IL-6 in the middle ear effusion was approved. It is recommended to conduct researches aimed to identify other cytokines as inflammatory markers.

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: Determination of mortality causes precisely, is very important in developing countries. Mortality rate is a helpful index for evaluating the quality of health in every society. However, recording of life events as well as mortality rates are difficult and conducted only in a few developing countries which account for a large percentage of the world’s mortality. Thus, it was attempted to conduct a study on mortality cases of under 18 year’s old corpses referred to the dissection laboratory of forensic medicine in Tehran from 2014 to 2015.
Methods: In this cross-sectional descriptive study, all cases of accidental deaths less than 18 years old which were referred to forensic medicine in Tehran have examined. All mortality data between April 2014 and April 2015 was completed by a questionnaire. This data were classified by age, sex, cause of referral, type of death, underlying disease, and cause of death based on autopsy results and positive findings of autopsy, pathology, and toxicology.
Results: In 2014 and 2015, 495 and 508 cases of under 18 years old were sent to the dissection laboratory of forensic medicine in Tehran, consequently. The mortality rate of 520 males and 483 females was recorded and it has risen from 2014 to 2015. The most common mortality causes are accidents, suspicious death, suicide, and car accidents.
Conclusion: The results showed that the mortality rate in males was higher than females, which is in line with the global findings. This may be due to cultural issues or the vulnerability of males. Study on causes of deaths, which recorded over two years showed that deaths in Tehran province are due to accidents, falls, strangulation, life-threatening poisoning and electrocution, birth disorders and suicides, which requires more studies on these subjects.

Abstract
Background: Cubital tunnel syndrome, a neuropathy of ulnar nerve, is the second most common entrapping syndrome in the upper limb surpassing carpal tunnel syndrome. This syndrome arises from a high pressure decompressing the nerve for a long time. Patients with cubital tunnel syndrome show numbness in the ring and small fingers. The aim of this study was to evaluate the etiology of cubital tunnel syndrome in patients who underwent surgery for treatment of the syndrome.
Methods: In this retrospective study, medical records of 100 patients who underwent surgery for treatment of cubital tunnel syndrome at Department of Neurosurgery, Poursina Hospital, Rasht, Iran from March 2008 to March 2017, were checked. The etiology of cubital tunnel syndrome including inflammatory, tumoral, vascular, orthopedic causes and anomalies in nerve site and information about age, gender, job, and weight were collected and analyzed.
Results: In this study, the mean±SD of age was 33.8±11.5 years. Females and males constituted 21% and 79% of the cases, respectively. Idiopathic and orthopedic etiologies were seen in 84% and 13% of the operated cases, respectively. Vascular, tumoral, and inflammatory causes were found in 1% of the cases. Regarding location of nerve involvement, 57% of the cases had the ulnar nerve entrapment between MCL (medial collateral ligament) and Osborne ligaments; and in 22% of the cases, the cubital tunnel was involved. Arcade of Struthers and medial epicondyle and medial intermuscular septum were involved in 8%, 8%, and 5% of the patients, respectively. Forty-five percent of the cases performed a repetitive manual task by hand and 1.9% of cases were vibrator workers. Moreover, 12.4% of cases had a history of cubitus valgus or cubitus varus. Finally, 20.9% and 18% of the cases suffered from obesity (BMI>30) and diabetes mellitus, respectively. Furthermore, one patient had a history of head injury with contractions of upper limb flexion and one patient had arthritis of medial epicondylitis.
Conclusion: The evidence from the present study indicates that the idiopathic cubital tunnel syndrome constituted the bulk of involvement on ulnar nerve in the patients. Job, obesity, and diabetes were the most important accompanying factors with cubital tunnel syndrome.

Abstract
Infertility as a vital process in human reproduction involves many couples worldwide. Although many genetic causes of infertility are known, the genetic basis of infertility in men is largely unknown. Therefore, the identification of genetic biomarkers in this field is important and genetic polymorphisms in key genes of the spermatogenesis pathway can be valuable biomarkers in this field. Gene's polymorphisms with specific genetic background and/or environmental factors can lead to the dysfunction in testicular function or the process of sperm production. Matrix metalloproteinases (MMPs) are a family of zinc-dependent enzymes that play an important role in extracellular matrix remodeling by activating gelatinases, collagenases, and proteolytic enzymes. These enzymes are essential for the regulation of cellular connections in the testis. Extracellular matrix degradation and connective tissue remodeling are important structural changes in germ cell migration that are controlled through important genes, including MMPs and their biological inhibitors. Given the important role of MMPs in the structural and functional characteristics of reproductive organs, genetic polymorphisms in MMP genes are significant because they can influence gene transcription and the biological function of proteins. Studies have shown that matrix metalloproteinases are involved in the degradation of extracellular matrix and play an important role in the process of spermatogenesis and sperm quality. This review article aims to evaluate the role of two common, functional MMP2 G1575A and MMP9 C-1562T polymorphisms in male infertility. The findings indicate that polymorphisms of MMP2 G1575A and MMP9 C-1562T can affect gene transcription, protein level, and enzymatic activity, and also, these variants can be as one of the genetic causes in male infertility among different ethnic populations. Therefore, identifying these molecular changes can help to adopt appropriates therapeutic and diagnostic measures as well as guide therapeutic approaches to intelligent therapies. To achieve a definitive conclusion and confirm the association of these polymorphisms with male infertility, evaluations of gene-gene and gene-environment interactions can be important for larger sample sizes of different ethnicities.
