Abstract
Background: Acute and chronic wound healing has always been problematic. Stem cells with or without the scaffold carrying these cells have been proposed as new methods in the treatment of wounds. In this case study we have tried to examine the effect of scaffold made of polyether sulfone (PES) alone, with stem cells and along with stem cell and growth factor on wound healing in rats.
Methods: This experimental study was conducted in Animal Laboratory of Hazrat Fatemeh Hospital in 2012. In this study, 48 rats were randomly divided into four groups. A wound created on the back of each rat at the size of 3×3 cm. The surface of the wound in the first group is covered with PES seeded with adipose-derived stem cell (ASC) and growth factor (GF), in the second group with polyether Sulfone seeded with ASC, in the third group only with PEWS, and in the fourth group (control) with Vaseline gauze. On 20th and 35th days, the surface of the wound was assessed by photography in order to understand the process of healing. In addition, on days 20 and 45, the histopathology characteristics of the samples were studied with a biopsy of the wounds.
|
Results: The Results of wound healing in the control group was better than the other groups and its statistical difference between others was meaningful. (P=0.008, P=0.013, P=0.001) On day 20, by examining histopathological characteristics including epithelialization, the number of inflammatory cells, the amount of angiogenesis and collagen synthesis in control group, we gained better results. (P=0.000), But on day 45, the results in different parameters were not equal.
Conclusion: polyether sulfone scaffold alone or with adipose-derived stem cells couldn’t improve the process of wound healing. Also adding vascular endothelial growth factor (VEGF) did not change the results significantly.

Background: Cartilage grafts is one integral component in the various fields of plastic surgery particular rhinoplasty. Surgeons usually use from various sources, including the septum of the nose, ears and rib. Complications such deformity and reabsorbtion may be created with use of the cartilage. Area of the removal of cartilage can prevent these complications. The aim of this study was to compare the absorption rate and viability of cartilage autograft between two common donor site, the rib and the concha.
Methods: This experimental study was performed on October 2014 in animal laboratory of Hazrat Fatima Hospital, Tehran, Iran. In this study, 15 New Zealand white male rabbits, weighing 2000-2500 g, approximately 12 to 16 weeks of age were used. In each rabbit, a piece of one ear and one cartilage was excised. After careful weighting of grafts, we implanted the rib cartilage graft into the left pocket and the conchal cartilage graft into the right one. After 8 weeks, the grafts were removed and weighed precisely and photography was carried out. The specimens were fixed in 10% formalin solution for histologic examination was. An example of hematoxylin and eosin staining and cut (H&E) were performed and samples of live chondrocytes and fibrosis were examined by a pathologist.
Results: We lost 3 rabbits during our study. The results showed that the average weight of a graft from the ear within 2 months, but this increase was not statistically significant (P= 0.152). In the rib graft weight loss over 2 months, and this reduction was statistically significant (P= 0.009). The resorption between two group was not significant but the amount of fibrosis was more in conchal cartilage graft.
Conclusion: According to the study it can be concluded that absorption rib cartilage is somewhat better results than the cartilage of the ear. More studies, in addition to cartilage implants longer human studies can contribute to more accurate conclusions.

Abstract
Background: Researchers and health specialists are increasingly obtaining information on chronic illnesses from self-reports. This study validates self-reports of hypertension, based on a recently fielded survey in Mashhad City, Iran.
Methods: In this cross-sectional study, we used the results of 2015 census in Mashhad City, a population based survey of people over the age of 30 (n=300745) to determine the proportion of self-reported hypertension. In this study, the data of the studied population was extracted from the databank of Sina Electronic Health Record System (SinaEHR®) and patients with ICD10 codes including I10 and I11 approved by doctors as a reference. Finally using SPSS software, version 20 (SPSS Inc., Chicago, IL, USA) and MedCalc (https://www.medcalc.org/calc/odds_ratio.php), sensitivity, specificity, positive predictive value, negative predictive value were calculated with 95% confidence interval.
Results: Sensitivity of self-reported hypertension was 23.92% (CI95%: 23.43-24.41), specificity 97.03% (CI95%: 96.97-97.09), Positive Linkelihood Ratio 8.06% (CI95%: 7.82-8.30), Negative Linkelihood Ratio 0.78% (CI95%: 0.78-0.79), Positive Predictive Value 46.34% (CI95%: 45.60-47.08), Negative Predictive Value 92.25% (CI95%: 92.20-92.29). The self-reported sensitivity to hypertension in males, Iranian individuals, single, aged 60 and over, body mass index lower 18.5 individual with university education was higher, which was 24.67%, 31.09%, 30.07%, 32.43% and 26.03% respectively.
Conclusion: Although the sensitivity of self-reported hypertension was poor in this study, but specificity and positive and negative predictive values were fairly good.

Abstract
Background: Oxford Shoulder Score (OSS) is a specific questionnaire for the assessment of pain and function in subjects with shoulder pain. The reliability and validity of the Persian version of this questionnaire have been shown previously. But its responsiveness has not been investigated yet. This study aimed to determine the Persian OSS responsiveness in subjects with shoulder pain.
Methods: This was a prospective cohort study design conducted in the Physiotherapy Clinic, School of Rehabilitation, Tehran University of Medical Sciences in 2018. Thirty-one subjects with shoulder pain (20 females and 11 males) with a mean age of 50±15.3 participated in this study. They completed the Persian OSS, Disability of Arm, Shoulder & Hand (DASH) questionnaire, and Visual Analog Scale (VAS) before and after 10 physiotherapy sessions. After the 10th session, the Global Rating of Change (GRC) was also completed. The statistical analysis included the Effect Size (ES), Standardized Response Mean (SRM), and the Spearman or Pearson correlation coefficients.
|
Results: The results showed that the ES and SRM of the Persian OSS were 1.73 and 1.79, respectively. The correlation between the Persian OSS and the VAS scores was 0.69 and between the Persian OSS and the DASH scores was 0.89. The correlation between the Persian OSS changes and GRC was not statistically significant (r=0.25, P=0.18). However, a significant moderate correlation was identified between the VAS and DASH with the GRC scores (r=0.43, r=0.42, respectively).
Conclusion: The Persian OSS has internal and external responsiveness for the assessment of subjects with shoulder pain. The Persian OSS, as a responsive instrument, can be used to investigate the effectiveness of interventions in the clinical settings and research to detect the changes in patients with shoulder pain. Further study with larger sample of patients with shoulder pain is warranted to confirm the findings and to estimate the minimally clinically important change.

Abstract
Background: Approximately 3% to 5% of obstetric patients will experience postpartum hemorrhage (PPH). Even though the most common reason for postpartum hemorrhage, as the main cause of maternal death, is uterine atony; other complications such as laceration, hematoma, inversion, rupture; retained tissue or invasive placenta; and coagulopathy may result in PPH. The main cause of retained placenta can be traced to the history of manual placenta removal, violent and numerous curettages, uterus anatomical abnormalities, placenta accreta or placenta previa, and history of cesarean section. Here, we have presented a case of retained placenta and uterus septum.
Case Presentation: The patient, a 36 years old female, multigravid 11 live 3 ,death 1 and abortion 6, with a history of four normal vaginal deliveries, and history of preterm premature rupture of membrane since the 16th week of pregnancy, was admitted to Imam Reza hospital, Mashhad University of Medical Sciences due to labor pain in 29th week of pregnancy. After a vaginal delivery, she was transferred to the operating room due to a retained placenta. During the initial diagnosis, the patient’s cervix was dilated and manual placental removal was not possible. The ultrasound results showed an 80mm heterogeneous tissue in the fundus, extending to the left cornu. There was no sign of accreta. During hysterotomy, the retained placenta was removed from underneath a thick layer of Uterine Septum, using sponge forceps. Five days later, the patient returned with severe pelvic pain and signs of peritonitis. Laparotomy and hysterectomy were performed on account of uterine incision necrosis.
Conclusion: The most crucial step in the treatment of retained placenta lies in the early detection of its cause. The treatment includes manual or Surgical removed of placenta which can result in bleeding, infection, and a lengthy recovery.

Abstract
Background: Understanding hand structures is necessary to diagnose its diseases and injuries. Several methods have been used to teach the anatomy of this body part. In this article, we introduce a new educational tool and examine the impact of its use in learning anatomy.
Methods: Color images of different layers of hand structures were connected with a spring. On each page, the desired structure was cut and that part could be turned from another direction so that the tool was beyond a booklet and could create a three-dimensional image of the region. In this way, a multi-layered structure was made that looking at each part of it and going to the next part was equivalent to removing a layer from the palm of the hand and observing the layer beneath. After making the educational tool, 280 students who participated in the study were divided into two groups: control (A) and experimental (B). Both groups participated in a pre-test. After teaching the theory of hand anatomy for both groups, the control group received practical training using the traditional method and the experimental group using the proposed educational tool, and both groups participated in a post-test and the scores of the pre and post-test groups were compared. Data were analyzed using SPSS 24 statistical software using Mann-Whitney and Wilcoxon tests.
|
Results: The pre-test scores of groups A and B were 3.48±1.197 and 3.49±1.481, respectively. The post-test scores of groups A and B were 6.97±1.504 and 10.54±1.303, respectively. Therefore, although the pre-test scores of groups A and B were not much different (P>0.05), the post-test scores of the two groups showed a significant difference (P<0.001). Students also expressed that using this educational tool has made learning hand anatomy more interesting for them.
Conclusion: The results of this study showed that the proposed educational tool is effective in the field of hand anatomy education.

Abstract
Background: Acute coronary syndrome (ACS) is one of the causes of disability and death. Levels of Uric acid, blood glucose, and dyslipidemia are the risk factors for the disease, but their role in electrocardiographic changes has not been studied. Based on this, this study aimed to investigate the relationship between some demographic and clinical characteristics with electrocardiographic changes.
Methods: This cross-sectional study was performed on 484 patients with Acute Coronary Syndrome admitted to Shahroud Imam Hossein Hospital from the beginning of January to the end of June 2018. In this study, the relationship between demographic, clinical and laboratory variables in patients with the acute coronary syndrome with STE, STD, Dynamic changes and inverted T waves were investigated. The required information was extracted from the Patients' records using the researcher-made checklist. Statistical analysis of data was conducted by using descriptive tests for estimating mean and frequency and statistical-analytical tests including chi-square and ANOVA were performed by SPSS software version 22.
Results: The results show that the proportion of STD deviations in women with ACS was 12.6% higher than in men, but the proportion of STE and Dynamic changes in men was 10.4% and 12.2% higher than women, respectively. The proportion of STD, STE, inverted T and Dynamic changes in people with hyperlipidemia was 67.8%, 77.6%, 64.7% and 75.8%, respectively. The proportion of STD, STE, inverted T and Dynamic changes in patients with hypertension were 0.12%, 5.1%, 11.2%, and 19.1%, respectively that there was a difference with patients without high blood pressure. Between addiction, fasting blood sugar and LDL with STD; Between History of heart disease, history of angiography, hypertension, creatinine and WBC with STE; and between creatinine and fasting blood sugar statistically significant differences were observed.
|
Conclusion: There were significant correlations between electrocardiogram changes, gender, addiction, hypertension, creatinine, LDL level, fasting glucose and white blood cell count.

Abstract
Background: Nuclear medicine imaging has shown high accuracy in evaluating the metabolism of colon cancer lesions. The aim of this study was to investigate the ability of radiomics features extracted from nuclear medicine images as non-invasive biomarkers of lesion metabolism in patients with colon cancer by examining the correlation of these features with SUV (standardized uptake value) max values.
Methods: The current study was a cross-sectional study that was conducted from July 2022 to July 2023 in the nuclear medicine department of Tehran University of Medical Sciences. In this study, PET/CT (positron emission tomography/computed tomography) images of 60 patients with primary colon cancer were used. Colon cancer lesions were manually delineated on PET images by an experienced physician and saved as VOIs (volumes of interest). Thirty-two textural radiomics features were extracted from each VOI, including feature groups of gray-level co-occurrence matrix (GLCM), gray-level run-length matrix (GLRLM), neighborhood grey-level difference matrix (NGLDM), and gray-level zone length matrix (GLZLM). Then, the correlation of these features with SUVmax values was investigated using the Spearman correlation coefficient statistical test. Also, the value of p<0.05 was considered as the significance level of the test.
Results: A comprehensive analysis revealed that more than 96% of the examined radiomics features specifically, 31 out of 32 exhibited a statistically significant correlation with lesion metabolism values, as indicated by p-values less than 0.05. Among these features, GLZLM_HGZE stood out with a high correlation coefficient of 0.9881, alongside a significance level of less than 0.0001. Similarly, GLZLM_SZHGE also demonstrated a strong correlation, with a coefficient of 0.9723 and a significance level below 0.0001, indicating a robust relationship with SUVmax values. In contrast, GLZLM_LZHGE was the only feature that failed to show a significant correlation with lesion metabolism values (p>0.05).
Conclusion: The radiomics method has the potential to be used as a completely non-invasive method to evaluate the metabolism of colon cancer lesions and facilitate the monitoring and treatment of patients with colon cancer.
