Abstract
Thyroid scintigraphy has been helpful in detecting and evaluation of thyroid nodules. Sodium pertechnetate Tc-99m is the most commonly used radionuclide for thyroid imaging because of its general availability, favorable dosimetric characteristics and low cost. But, there are reports of occasional disparity in isotope uptake in lesions compared with radioiodide. In order to determine percentage and clinical significance of this disparity, we screened 101 patients with solitary functioning nodules using sodium pertechnetate TC-99m in comparison with subsequent Iodine-131 scan in research institute for nuclear medicine. We conclude that sodium pertechnetate TC-99m is a reliable radiotracer for the detection and evaluation of thyroid nodules and there is no need for the subsequent Iodine-131 scan.

Abstract
Radioiodine therapy is the safest, simplest, least expensive and most effective method for treatment of Graves' disease. Due to difficulties in previous methods for dose determination, fixed dose method of 1-131 is now considered the best practical method for 1-131 therapy in Graves' disease, but there is no consensus on the dose. We compared two routinely recommended fixed doses of 5 and 10 mCi for this purpose.
Materials and Methods In this clinical trial, 59 patients with Graves' disease referred for radioiodine therapy were randomized into two groups, one group was treated with 5 mCi of 1-131 and the other with 10 mCi. All patients were followed for two years, with 6-month intervals.
Results: Totally, among 59 patients treated with 1-131, 20 (33.9%) patients became euthyroid and 19(32.2%) became hypothyroid, while failed therapy (no response or relapse) was noticed in 20 patients (33.9%). In the group treated by 5 mCi (33 patients), 10(30.3%) were euthyroid, 6(18.2%) were hypothyroid (overall cure of ^8.5%), while 17(51.5%) remained hyperthyroid by the end of the follow-up period. From the 26 patients treated with 10 mCi, the euthyroid and hypothyroid states were observed in 10(38.5%) and 13(50%)patients, respectively (overall cure rate of 88.5%), and hyperthyroid state in 3(11.5%). No relationship was noted between the outcome and age, sex, size of the thyroid gland and thyroid uptake, but the relationship between the disease outcome and the amount of administered radioiodine was significant (P<0.003). Although the incidence rate of early hypothyroidism (by the end of 2 years) in the group treated with 5 mCi is less than those treated with 10 mCi, the incidence of failed therapy is higher in the former group. In addition, it is known that long-term hypothyroidism prevalence is not significantly different by using different doses of I-131. On the other hand, if the initial dose is so little to cure, cost and time for perfect treatment, number of office visits and morbidity due to untreated hyperthyroidism are markedly increased.
Conclusion: Regarding lower rate of failed therapy with 10 mCi, and as there is no significant difference in late hypothyroidism between low doses and high doses of I-131, we concluded that 10 mci is the optimal fixed dose for treatment of Graves' disease.

Abstract
Background: The purpose of this study was to evaluate the effect of treatment with radioactive iodine on the function of gonads in males and females with follicular and papillary thyroid carcinoma.
Materials and Methods: Consenting patients in the reproductive age were grouped according to the cumulative dose of received radioiodine and followed for at least 12 months. For all men, serum levels of FSH, LH, and testosterone were measured some (53 cases) were also studied by semen analysis. For women, tests for serum levels of LH, FSH, estrogen, and progesterone were performed.
Results: Overall, 246 patients (159 females, 87 males) were studied. In 87.4% of men, there was an increase in serum FSH level after radioiodine therapy, in 20.7% of whom the level remained high during follow-up period. The average serum level of FSH after each course of treatment was significantly higher than the level before treatment (p<0.01), and there was a meaningful correlation with the cumulative dose of received iodine (p<0.001). Reduced number of sperms was shown in 35.8% of male patients, among whom 73.7% also showed reduced motility. In 36.8% of the patients with reduced sperm number (13.2% of the total), this finding was persistent during the follow-up period. Increased level of FSH was correlated with reduced sperm counts in all doses (p

Abstract
Background: Telomerase as an enzyme with reverse transcriptase activity has an essential role in telomere maintenance by adding a telomere repeat sequence to the 3' end of chromosome and is important for regulating of many processes in embryonic development including cell proliferation and differentiation. Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) with a self-renewal capacity are cells that can differentiate into various germ layer derivatives including neural cells and cardiomyocytes, and undergo biological changes during long-term cultivation. Hence, the passage number in which the cells expanded seems to be very important for proliferating and differentiating. This study was aimed at investigating the relationship between the telomerase activity and the growth rate of (hUC-MSCs) at different passages.
Methods: This experimental study was performed in Ardabil University of Medical Sciences, Iran, from March 2014 to December 2014. The umbilical cord samples were obtained from full-term neonate hospitalized in Alavi’s Hospital in Ardabil under sterile conditions. The umbilical vessels were clear off and the small pieces of the umbilical cord were cultured in Dulbecco's modified eagle's medium (DMEM) supplemented with 20% fetal bovine serum (FBS). Then, the hUC-MSCs were harvested from passage one to three to calculate the population doubling time (PDT) and extract proteins by using CHAPS lysis buffer. Finally, the telomerase activity of the cells at different passages was measured by telomeric repeat amplification protocol (TRAP) and qRT-TRAP assays.
Results: The hUC-MSCs population doubling time at passage from 1 to 3 were calculated as the average of 54.68±1.92, 55.03±1.71 and 69.41±2.54 hours, respectively, suggesting the higher cell passage number, the more extended PDT. The threshold cycles (CTs) for the telomerase activity also showed 30.58±0.51, 27.24±0.74 and 32.13±0.75 for the cell passage from one to three, respectively, representing the significant increasing in telomerase activity at passage two compared with the other passages (P= 0.021).
Conclusion: Analysis of the growth curve, PDT determination and measurement of telomerase activity of the human umbilical cord-derived mesenchymal stem cells showed that the long-term cell culture can affect on the cell proliferation and the telomerase activity.

Abstract
Background: Burns is a major health problem due to severe side effects and limited financial resources. Some herbs are cheap and available, such as Arnebia euchroma can be effective treatment of burn wounds and reduce recovery time. The aim of this study was to evaluate the effect of Arnebia euchroma ointment on healing of deep second-degree burn wound in rats.
Methods: This experimental study was conducted in animal laboratory of Hazrat Fatemeh Hospital in 2015, Tehran. In this study 24 male Sprague-Dawley rats weighing approximately 300 to 350 g were selected. After general anesthesia, back of each rat was shaved with clipping device. Then second-degree burn with the area of 2×4 cm was induced on them. Rats were randomly divided into 2 groups, 12 in each. The surface of the wound in the first group was covered with Arnebia euchroma ointment and in the second group with Vaseline. Dressing was done daily until complete recovery and the wound healing process was monitored by photographing every five days. On day 20, the samples were sent for pathological evaluation of the amount of collagen and inflammatory cells.
Results: Results showed that, during days from 5 to 15 the extent of the wounds reduced in both groups (P= 0.000). The reduction of wound size was significantly higher in Vaseline group compared to Arnebia euchroma ointment group (P= 0.040). The results of the pathological examination showed no significant difference in the amount of collagen and inflammatory cells in the two groups.
Conclusion: It seems Arnebia euchroma ointment to some extent reduced the extent of the wound especially in superficial burns compared to other dressings. However, it is better to conduct more similar studies with a larger sample size and different method and change in timing of dressing.

Abstract
Background: Head lice (Pediculus humanus capitis) are obligate ectoparasites of mankind, and are mainly transmitted head to head directly from one person to another. Human head lice treatment is faced with some challenges such as lack of complete treatment and the need for treatment repeatedly. The aim of this study was to evaluate the efficacy of two pediculicide products (substances used to treat human head lice infestation); 1% permethrin shampoo and 4% dimethicone lotion.
Methods: In this clinical trial, 140 cases of head lice infested people that were referred to the urban comprehensive health centers of Qom provincial health center related to Qom University of Medical Sciences and Health Services, Iran, from April to March 2017. The cases randomly were treated with two pediculicide products; 1% permethrin shampoo and 4% dimethicone lotion. The outcome of the treatment included removal of adult human head lice, nymphs, and nits in confirmed human cases at 14 and 21 days after starting treatments were considered.
Results: The success rate of human head lice infestation treatment in case of double use (at one-week intervals) with 1% permethrin shampoo and 4% dimethicone lotion was 65.7% and 62.9%, respectively. There was no statistical significance between the therapeutic effects of the two above-mentioned methods (odds ratio=1.22, P=0.59, CI=0.6-2.5). While the recovery rate of men compared to women was 3.8 (P=0.036), it was 3.1 (P=0.05) for housewives compared to students, and in families with one case compared to ones with more than one patient, this rate was found to be 3 (P=0.034). Family size was one of the most important variables that had a significant effect on the therapeutic rate of 1% permethrin shampoo and 4% dimethicone lotion.
Conclusion: The findings of this study do not support the reduction in efficacy of 1% permethrin shampoo and 4% dimethicone lotion as pediculicide products.

Abstract
Background: Previous researches have provided contradictory results about on working memory performance after the coronary artery bypass graft (CABG). In addition, studies have focused on the elderly community. For this reason and with regard to the importance and direct effects of working memory on the quality of life human. This study was designed to compare working memory of young CABG patients with age range of 30-55 years one year postoperatively with healthy subjects.
Methods: In this Case-control study, which was conducted from February 2017 to October 2018, two groups of people, 40 patient men with coronary artery bypass graft that admitted to the heart center of Tehran in last year and 64 healthy males were selected with using available sampling method. Both groups were tested with Wechsler's working memory scale.
Results: The results of the study showed that the mean and standard deviation of the age of coronary artery bypass graft patients were 52.65 and 5.559, respectively, and the mean and standard deviation of healthy subjects were 41.81 and 8.619, respectively. The results showed that The two group had significantly difference (P<0.01), in the sub scales of the working memory including of the forward auditory memory and reverse auditory memory, total score of auditory memory, reverse visual memory and auditory memory span and the two groups had significantly difference (P<0.05), in the total score of visual memory. But the two group had not significantly difference (P>0.05) in the forward visual memory (CABG [mean=5.40 & standard deviation=1.41] Healty people [mean=6.13 & standard deviation=3]) and visual memory span (CABG [mean=5.35 & standard deviation=1.12] Healty people [mean=5.56 & standard deviation=1.97]). The results showed that Patients with CABG than healthy people have overall poorer results for all sub scales the of working memory test.
Conclusion: The results of this study confirm the prevalence of relatively high cognitive decline, especially in working memory after CABG, and provide a pattern of persistence of cognitive decline after one year of coronary artery bypass surgery in young patients aged 30 to 55 years.

Abstract
Background: Nonpuerperal uterine inversion is a rare medical condition that many gynecologists might not be encountered even with one case during their entire medical practice. It refers to the expulsion of uterine corpus from the dilated cervix resulting in uterus being turned inside out. There are two kinds of uterine inversion, puerperal and non-puerperal, which the second condition is less common. Acute uterine inversion usually presented by crampy abdominal or pelvic pain, vaginal bleeding, anemia, and even symptoms of severe sepsis. We describe a case of uterine inversion in a postmenopausal woman.
Case Presentation: A 66 years old grand multiparous woman (6 normal vaginal delivery) who was menopause since 15 years ago, was referred to the emergency unit of an academic hospital of Mashhad University of Medical Sciences at October 2016 due to postmenopausal uterine bleeding, cramp-like abdominal pain and mass protrusion from the vagina. The vital sign was stable at the first visit but a big non-necrotizing red vaginal mass was protruded from vaginal opening that connected to other soft intravaginal mass. Abdominal ultrasonography revealed the dilated vaginal cuff and some air-fluid levels in the uterine cavity. The patient referred to the operative room and vaginal myomectomy was done with diagnosis of pedunculated submocusal leiomyoma. Then, total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed after the correction of uterine inversion by abdominoperineal approach.
Conclusion: Acute uterine inversion is a potentially dangerous condition (due to vaginal bleeding, severe abdominal or pelvic pain, and the possibility of uterine necrosis and even systemic infection). This condition should be considered as an important differential diagnosis as a vaginal mass in the post-menopausal period.

Abstract
Background: Currently, cutaneous leishmaniasis (CL) as a parasitic disease is treated with Glucantime and Pentostam in most of the endemic countries. This study aimed to identify factors affecting the glucantime therapy duration rate in patients with CL using a survival analysis model.
Methods: This retrospective descriptive-analytic study was conducted on 1017 CL patients that were referred to the urban and rural comprehensive health centers of Qom Province under the supervision of Qom University of Medical Sciences, Qom, Iran, from April 2014 to March 2019 through the census. The recovery time was measured by the Kaplan-Meier method, and then the survival function was plotted based on each variable. The Log-Rank test was applied to analyze the differences among variables, and after the evaluation of the PH assumption by Shoenfeld residuals, a stepwise forward Cox progressive regression was used to determine factors affecting intralesional or systematic treatment duration in the patients involved with cutaneous leishmaniasis.
|
Results: The recovery rate of lesions in cutaneous leishmaniasis cases was found to be 96.7% by the intralesional treatment and 93% by the systematic one. The mean recovery time for cutaneous leishmaniasis patients was 8.00 weeks for the intralesional treatment and 18.00 days for the systematic treatment. The only significant variable in the intralesional treatment was observed on cases with thigh lesions, meaning that those patients who had CL lesions on their thighs experienced a significant reduction in their recovery time. Furthermore, the lesion variable was also significant (P=0.039) as the recovery chance of those patients who had four or more CL lesions was 30% less.
Conclusion: The existence of lesions on CL patients’ thighs and a low number of lesions in CL patients can decrease the recovery time. The use of the Cox regression model in medical studies is more appropriate because not only does it consider the occurrence of the event but also it can reveal the occurrence time of the disease.

Abstract
Background: Vitamin B12 deficiency is one of the most well-known disorders due to long-term use of metformin due to interference with its absorption.
Methods: This double-blind randomized trial was conducted from June to October 2016 at Shahid Beheshti Hospital in Qom on 60 patients in the age group of 30 to 60 years with a history of type 2 diabetes for one to two years and taking metformin in the amount of one to two grams. Patients were divided into two groups of 30 people. The intervention group received metformin with 1 gram of calcium carbonate daily, and the control group received metformin without calcium. Each of the patients in the intervention group was given 200 calcium carbonate tablets. Vitamin B12 levels of the patients in both groups were measured before the start of the intervention, and they were evaluated in terms of neuropathy according to the Michigan questionnaire. Vitamin B12 of patients and neuropathy in two groups were measured before the intervention and after three months.
Results: There was a difference between the two groups in terms of gender, and no significant difference was observed between the mean ages in the two groups. The mean level of vitamin B12 before receiving calcium in group A (intervention) was lower than group B (control) (P=0.036) and after receiving calcium, the level of vitamin B12 in the intervention group increased (P=0.002). In the control group, the level of vitamin B12 decreased (P=0.030). (P=0.006), and in the control group there was no significant difference in the examination of neuropathy (P=0.2).
|
Conclusion: Oral calcium daily intake increases vitamin B12 levels in patients with type 2 diabetes and calcium may be able to moderate the decrease in serum vitamin B12 levels induced by metformin in patients with type 2 diabetes.
