- چکیده انگلیسی: Background: Perianal fistula is a complicated disorder and most difficult to manage. New treatment methods would help surgeons to achieve a better outcome in patients with perianal fistula. Human amniotic membrane (HAM) has positive effects on wound healing in several conditions. The present study aimed to further determine the effect of HAM on wound healing of perianal fistula in rabbits.Methods: In a prospective experimental study, 14 male rabbits (aged 4-6 months and weighing 3-4 kg) were randomly divided into 2 groups. After 12 weeks, the high type perianal fistula was repaired with endorectal flap (ERF) and ERF plus HAM in the control and case groups, respectively. In all rabbits of the case group, a 1×1 cm width wrap of HAM was applied and fixed around the ERF site. Three weeks later, the repaired site of the perianal fistula was sent for pathologic wound healing scoring. The results were analyzed with the SPSS 21.0 software using Mann-Whitney test. Results: Six rabbits of each group survived the study period. There was a statistically significant difference in wound healing between the case and control groups (P<0.001). Wound healing process in the case group occurred better and faster than the control group.Conclusion: HAM has an effective role in enhancing the ERF procedure and considered appropriate. A combination of HAM with other methods is recommended.

- چکیده: . مطالعه حاضر سواد سنجش درک مطلب دو گروه از معلمان ایرانی دروس زبان انگلیسی برای اهداف ویژه در رشته های پزشکی را از نظر سنجش تکوینی مورد مطالعه و بررسی قرار داد. برای این کار ، 21 مدرس زبان ویژه ، 8 مدرس محتوا و 13 مدرس زبان انگلیسی ، از پنج دانشگاه در این مطالعه شرکت کردند. داده های مورد نیاز ازطریق یک پرسشنامه 40 سوالی ، مصاحبه نیمه ساختار و مشاهدات غیر مشارکتی جمع آوری شد . نتایج توصیفی داده های کمی و کیفی نشان داد که عملکرد سنجش درک مطلب مدرسین زبان انگلیسی و محتوا تقریباً یکسان است. همچنین نتایج نشان داد که معلمان محتوا دانش کمی در مورد سنجش تکوینی کلاس درسی داشتند. اگرچه مربیان زبان انگلیسی در مورد دانش توافق گسترده تری داشتند ، اما در عمل رد و اثر کمی از آن یافت شد. از نظر اصول ، هم مدرسین زبان انگلیسی و هم محتوا توافق داشتند که اصول سنجش برای اندازه گیری پیشرفت دانشجویان ضروری میباشد. برای مقوله مهارت ، برخلاف معلمان محتوا ، مدرسین زبان انگلیسی بر این عقیده بودند که این مقوله بسیار اساسی است.ولی ،آنها این مقوله را در فعالیتهای ارزیابی خود بکار نبردند..
- چکیده انگلیسی: The current study investigated the language assessment literacy of two groups of Iranian medical ESP practitioners while teaching reading comprehension under formative assessment lens. To do so, 21 ESP instructors, 8 content and 13 ELT instructors, from five universities in Iran were recruited to participate in the study. A 40-item questionnaire, semi-structured interview, and non-participatory observations were employed by the researchers to collect the required data. The descriptive results of both quantitative and qualitative data indicated that the ELT and content teachers’ reading assessment performances were almost the same. The results also revealed that the content teachers had limited knowledge about formative classroom assessment (FCA). Although the ELT instructors were in broader agreement on the knowledge category, in practice, little trace of it was found. In terms of the principles, both the ELT and content instructors agreed that assessment principles were necessary for measuring students’ achievement. For the skill category, contrary to the content teachers, the ELT instructors were on the belief that this category was crucial; however, they did not implement it in their assessment activities.

- چکیده:
- چکیده انگلیسی: Background: Fecal incontinence is an embarrassing problem and decreases the woman’s quality of life. The literature has shown that women with obstetric trauma especially by episiotomy had damaged anal sphincter (Internal and External). We aimed to find the role of episiotomy in the fecal incontinence in women after delivery.
Methods: In this study, 71 females with previous vaginal deliveries were investigated by endoanal ultrasonography. The degree of FI was measured using the incontinence score of Wexner. The number of episiotomies was measured for each patient.
Results: The mean Wexner score was 9.0±0.7 in the incontinent patients. The mean of normal vaginal delivery was 3.48±0.3 and 33.8% of the patients whom had a history of hemorrhoidectomy. Of patients, 70% had undergone one or more prior episiotomies during their deliveries.
Conclusion: Episiotomy could be one of the risk factors in fecal incontinence but we did not find any significant difference in Wexner score between patients with or without episiotomy. Endoanal sonography seems an effective tool to evaluate and prediction of anal injury during episiotomy in some critical cases.- انتشار مقاله: 09-04-1399

- چکیده:
- چکیده انگلیسی: Background: Cancer research is highly dependent of large amount of data and high quality samples which can be provided by networks to enable large-scale multi-center research projects. Biologic materials, such as blood, tissue samples, DNA, body fluids and the related data obtained in cohorts and clinical trials are valuable sources for research which should be managed by policies and standard operating procedures as biorepositories or biobanks.
Methods and evidence acquisition: The authors investigated and summarized pubmed database articles using biobanks and describing the policies.
Conclusion: biobanking as a young discipline in different countries needs new technologies, standards and harmonization. In this review article, we have an overview on biorepository, cancer biobanking and the emerging registry in Iran.

- چکیده انگلیسی: Abstract
Background: Colorectal cancer causes many deaths worldwide and rectal cancer includes one-third of them. Surgical mesorectal excision along with preoperative neoadjuvant chemoradiotherapy is known as the standard treatment for rectal cancer. However, inaccurate preoperative staging is a main concern which leads to large number of patients not being treated with neoadjuvant therapy. Selection of the best treatment approach for these patients is controversial. Although significant better survival was observed is patients who received postoperative adjuvant chemoradiation compared with patients who treated with surgery alone, other studies did not find such results. Due to these contradictory results, this study was designed to further evaluate the survival outcomes in rectal cancer patients who received adjuvant chemoradiotherapy without neoadjuvant therapy. Methods: Totally 197 rectal cancer patients who received adjuvant chemoradiation were included in this study. The demographic and clinico-pathological characteristics of the patients were evaluated by statistical analysis. Results: Based on the univariate cox regression, poor disease free survival (DFS) was significantly associated with male sex and T3 stage. Poor overall survival (OS) was also associated with stage II/III, T3/T4, NI/NII, grade II/III, positive node number (> 3), perineural invasion, lymphovascular invasion, and margin involvement. According to the multivariate cox regression, independent predictive factors for DFS were T3 andT4 stage, and for OS were also T3/ T4 stage, grade II/ III and lymphovascular invasion. Conclusions: Taken together, obtained results indicated that combined adjuvant chemoradiation contributes to improve survival outcomes in the rectal cancer patients who did not received neoadjuvant therapy.- انتشار مقاله: 06-09-1398

- چکیده:
- چکیده انگلیسی: Context: The incidence of colorectal cancer has significantly increased in Iran during the last decade. Accumulating evidence suggests
that there is a significant correlation between genetic variations such as polymorphisms and colorectal cancer. Therefore,
identification of critical polymorphisms related to colorectal cancer can contribute to find individuals at high risk of CRC.
Evidence Acquisition: The focus of this review was on published articles in English about the association between different single
nucleotide polymorphisms and colorectal cancer in the Iranian population. Evidences were gathered by searching online medical
databases including Google scholar, Pubmed, Scopus and Science Direct.
Conclusions: Various single nucleotide polymorphisms of critical genes indicated significant association with colorectal cancer in
the Iranian population. New polymorphism markers for high risk individuals have been recognized through further investigations
to reduce the incidence and mortality of colorectal cancer.
