Volume 64, Issue 4 (7-2006)
Abstract

Background: Rotator cuff tendon tear injury is one of the most frequently seen orthopaedic conditions, and surgical repair of rotator cuff tears is a common procedure. The purpose of the present study was to determine the results of full-thickness rotator cuff repair and to look for predictors of outcomes.

Methods: we studied 27 patients (17 men and 10 women with a mean age of 57.7 years) who underwent open rotator cuff repair surgery for full-thickness tear between 2001 and 2005 at the Imam Khomeini Hospital and were subsequently followed-up for 6 and 12 months after surgery. The shoulder function was assessed by Constant classification and factors potentially associated with outcomes were

Results: The mean of preoperative Constant score (CS) was 45.8 ± 14.1 after 12 months, 6 patients (22.2%) had good results and 21 patients (77.8%) had excellent result according to CS. Pain relief was generally satisfactory. Using multiple regression analysis, treatment was significantly correlated preoperative CS and acromio-humeral interval (AHI) however, no correlation was found between the result of the treatment and pretreatment atrophy, tear size, acromial morphology, preoperative symptom duration and age.

Conclusion: In this study, a standard rotator cuff repair technique reduced pain severity and was associated with good results, however larger studies are necessary to define the long-term outcome of this procedure.

Feizy V, Ghazi P, Dolatshahi M, Hatmi Z N,
Volume 65, Issue 4 (7-2007)
Abstract
Background: This study aimed to assess the quality of life in vitiligo sufferers and its relationship with a number of variables such as age, gender, educational level, place of residence, marital status, disease duration, disease extension, visibility of lesions and skin phototype (SPT).
Methods: In this study we evaluate the quality of life in patients with vitiligo attending Razi Hospital in July and August 2005. Permission from Professor Finlay was obtained to use the DLQI (Dermatology Life Quality Index) questionnaire to evaluate the quality of life. One hundred patients with at least one vitiligo patch (age range= 14–57) answered the question-naire. Other survey questions about mentioned variables were also answered. Scoring was done according to Finlay`s guidelines. The higher the score, the greater the impairment of quality of life.
Results: The mean DLQI score in our study was 8.16 (sd=5.423) with a minimum of 0 and a maximum of 28. There were statistically significant relationships between DLQI scores and marital status, skin phototype and disease extension independently, but not between DLQI scores and other variables. The mean DLQI score was significantly higher in married compared to single patients. In fact this difference was significant in women. Married women had a statistically higher score than single women while single and married men had no significant difference. Patients with Skin Phototype IV showed a higher DLQI score than other SPTs, which was statistically notable (p=0.000). The patients with more disease extension had higher score that was statistically significant (p=0.000).
Conclusions: This study shows that vitiligo has a major impact on the quality of life and indicates specific groups that are most affected by the disease. Hence, dermatologists should pay attention to the psychologic effects of this cosmetic disease and try to decrease its extension and disfiguring effects by various treatment modalities.

Laal M, Granpaye L, Khodadi F, Salavatipour A, Sadeghi Ar,
Volume 66, Issue 6 (9-2008)
Abstract

Background: Various imaging tests as well as different scoring systems based on symptoms, signs and laboratory findings are commonly used to improve diagnostic accuracy in acute appendicitis. The aim of this study was to compare the diagnostic accuracy of MANTRELS scoring system (designed by Alfredo Alvarado), which is based on symptoms, signs and laboratory results, with sonographic findings.

Methods: In this prospective observational study, 106 patients with acute abdomen suspicious of acute appendicitis at Sina Hospital, Isfahan, Iran, were studied from March 2004 to February 2006.

Results: The disease was most common in patients aged 20-29 years, with male predominance. All patients had appendectomies. One hundred patients had acute appendicitis and six had negative appendectomy. Among the patients with acute appendicitis, 88% had an Alvarado score of ≥6 and 12% had a score of ≤5. Among the six patients with negative appendectomy, 66.7% had Alvarado scores of ≤5 and 33.3% had scores of ≥6, which was significantly different (p=0.005). The sonographic results were abnormal in 71.9% of patients with acute appendicitis and in 25% of patients with negative appendectomy, which was not significantly different (p=0.08). In our study, the diagnostic accuracy of an Alvarado score ≥6 was 88% and that of the sonographic results was 71.9% for acute appendicitis. If the Alvarado score ≥6 and abnormal sonographic findings are considered together, the diagnostic accuracy improves to 97.2%.

Ahmadi Amoli H, Zafarghandi Mr, Tavakoli H, Davoodi M, Khashayar P,
Volume 66, Issue 11 (2-2009)
Abstract

Background: Trauma is a common problem in the world, predominately affecting young adults. Considering the high mortality rate in patients suffering from thoracic trauma, the condition is considered to be extremely important. The purpose of this study was to evaluate the prevalence and the epidemiology of chest trauma as well as the severity of the resulted injury in Tehran, Iran.

Methods: This prospective, descriptive study was conducted on patients admitted to three medical centers in Tehran during June 1997 and 1998 due to chest trauma. The data on the demographic information of the patients, the mechanism of the trauma and the severity of the injury were collected and analyzed.

Results: Three hundred forty two patients were admitted to hospital due to thoracic trauma the majority of which were male adults. Blunt trauma especially secondary to motor vehicle accidents were the most frequent cause of chest injury in the studied patients. In 280(82%) of the cases, another form of trauma was also reported. Chest wall injury was the most common type of thoracic trauma in these patients. The trauma was reported to be mild in 181(53%) of the patients (ISS<7). Only 42(12%) patients required surgical intervention. The overall mortality rate was 14% which was reported to be ISS- related.

Conclusion: Chest injury is quite prevalent among trauma patients and is associated with other injuries in a considerable number of the patients. This type of trauma is associated with a high mortality rate among elderly and therefore needs special attention and care.

Niroumanesh Sh, Mohebi M,
Volume 67, Issue 1 (4-2009)
Abstract

Background: Previous studies have suggested the presence of a relationship between the increase of NRBC and the duration and intensity of asphyxia. The purpose of this study was to evaluate the relationship of fetal heart rate pattern and the number of NRBC's in umbilical cord blood sample at birth.

Methods: We enrolled 322 pregnant women with healthy, term fetuses who referred to Mirza Kouchak Khan Hospital for pregnancy termination in 2005 in a case-control study. All patients underwent continuous FHR monitoring and based on their FHR pattern, they were divided into two groups with normal FHR pattern and at least one abnormality in FHR pattern (including absence of beat to beat variability absence of proper acceleration and early, late, variable and prolonged deceleration). Samples of umbilical cord blood were evaluated for NRBC count and pH immediately after birth. The variables were compared in these two groups.

Results: The mean NRBC count was significantly higher in patients with any kind of deceleration (late, variable, early or prolonged) in comparison with controls (respectively 11.88±4.406, 8.32±4.64, 10.58±5.366, and 4.11±4.913 vs. 0.93±1.790 in controls). Furthermore the mean NRBC count was significantly higher in patients with absence of acceleration or beat to beat variability (10.73±5.07 and 13.73±3.58 vs. 1.47±2.50). There was a negative correlation between 5th minute Apgar score and umbilical cord blood sample with mean NRBC count of umbilical cord blood sample.

Conclusion: Any abnormality in FHR pattern is associated with a significant increase in mean NRBC count of umbilical cord blood sample. There is also a significant relationship between the 5th minute Apgar score and umbilical cord blood sample pH, and mean NRBC count in umbilical cord blood sample.

Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: This study was designed to explore the contribution of risk factors for coronary artery disease (CAD) in patients with indication for coronary angiography. Coronary angiography is defined as the radiographic visualization of the coronary vessels after injection of radio opaque contrast media. Despite the recognition of risk factors for CAD, the association between related risk factors and angiographic findings remains controversial. The aim of the present study was to explore the association between Gensini scores and major cardiovascular risk factors in patients with indications for coronary angiography.
Methods: We retrospectively enrolled 495 patients who had been hospitalized at Dr. Shariati Hospital during September 2009 to September 2010 and had undergone coronary angiography. The patients were evaluated for the severity of coronary lesions on the angiogram by Gensini scoring system. The patients were also evaluated for the presence or absence of DM, hypertension, family history of cardiac diseases, low HDL, hyperlipoproteinemia, hypertriglyceridemia and cigarette smoking. Statistical analysis wad done to find any relationship between Gensini scores and cardiovascular risk factors.
Results: The study population consisted of 249 men (50.3%) and 245 woman (49.5%) with a mean age of 58.1±10.3 years. A positive correlation was found between age (P=0.04), sex (P=0.008), HDL (P=0.04) smoking (P=0.0001) and diabetes (P<0.013) with Gensini scores.
Conclusion: In patients with indications of angiography, Gensini scores provide valuable prognostic information on cardiovascular risk factors. Age, sex, HDL, smoking and diabetes are related to the severity of coronary lesions on the angiograms.

Volume 69, Issue 10 (1-2012)
Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: One of the difficulties in acetabulum surgery is appropriate exposure of the site of surgery. Trochanteric flip osteotomy is one of the surgical methods for superoposterior and posterior acetabulum exposure. However, due to possible complications some surgeons prefer to avoid this procedure. This study was undertaken to determine the outcome of surgical treatment of acetabular fracture using trochanteric flip osteotomy.
Methods : In this prospective cohort study, 14 patients with acetabular fracture who had been admitted in Imam Khomeini Hospital in Tehran, Iran, during 2003-2006 underwent trochanteric flip osteotomy. The patients were followed for at least one year post-surgically. Demographics, radiologic findings, intensity of pain using visual analogue scale (VAS), Harris hip score (HHS), force of hip abductors and complications were noted. Data analysis was performed using SPSS ver. 13.
Results : The mean HHS was 82.5 (55-95). Heterotopic ossification was observed in three patients. There were no cases of postoperative infection or non::::union::::. Only two patients showed displacement of osteotomized fragments. Reduction was anatomic in 10 patients. In one patient, the force of hip abductors was three-fifth. The mean hip pain was 3.4 based on VAS. There were no cases of femoral head osteonecrosis. With respect to HHS, the final hip status was excellent and good in four and six patients, respectively. Three patients had fair and only one patient had poor condition.
Conclusion: It seems that trochanteric flip osteotomy has much fewer complications in comparison to other methods justifying its use in such cases.

Abstract

Background: Inadequate ventilation, esophageal intubation and difficult intubation are the most common adverse respiratory outcomes in patient undergoing anesthesia .The aim of this study was to compare Mallampati test in supine and sitting positions in traditional approach and during phonation for predicting difficult laryngoscopy and intubation.
Methods: In this study performed in Imam Khomeini Hospital in Tehran, Iran, Mallampati test was performed on 661 patients who met the inclusion criteria for the study. The test was done in supine and sitting positions with and without phonation by a rater who was blind to Mallampati test. Subsequently, laryngoscopy view and difficult intubation were evaluated in the four aforesaid positions by Mallampati test for predicting difficult laryngoscopy and intubation. For each situations, sensitivity, specificity, positive and negative predictive values and accuracy were calculated.
Results: Overall, 28 (4.2%) patients had difficult laryngoscopy and 9 (1.4%) patients had difficult intubation. The highest sensitivity for Mallampati test in predicting difficult laryngoscopy and intubation was in supine and sitting positions without phonation, and the highest specificity was seen in sitting position with phonation. Negative predictive values were more than 95% in all different positions for Mallampati tests and the highest positive predictive value was seen in supine position with phonation.
Conclusion: According to our findings, the highest correlation between Mallampati test and different positions in predicting difficult laryngoscopy and intubation was seen in supine position with phonation. Phonation improved Mallampati score in supine rather than sitting position.

Af Zand Parsa, N Gilani Larimi, A Esteghamati, M Motevalli,
Volume 71, Issue 2 (5-2013)
Abstract

Background: It has been shown that coronary artery calcium scoring (CACS) can be used as a diagnostic method in coronary artery disease (CAD). The relationship between CACS and calcium metabolism in the body has been shown. The arterial calcification is an organized process similar to bone formation which is controled by parathormone (PTH). The relationship between PTH as an osteoregulatory factor and CACS has been also indicated. In this study, we tried to assess the value of serum PTH and CACS in patients planned to undergo coronary angiography (CAG) in order to find a simple, cost -benefit, noninvasive way, for ruling in/out obstructive CAD.
Methods: In a cross sectional study in Imam Khomeini hospital in 1390, CACS by using non-enhanced multi detector computed tomography (MDCT) and measurement of serum level of PTH, Calcium and Phosphate were done in 178 patients suspected to CAD which were scheduled to undergo coronary angiography serum PTH was measured by immuno-radiometric assay (IRMA) and serum Ca and Phosphate were measured by spectrophotometry methods.
Results: Of 178 Patients, 50 patients were females and 126 patients were male. Mean age of them was 56.2±11.6. The correlation coefficient between CACS and Gensini score (0.507, P<0.001), PTH (0.037, P=0.693), Ca (0.062, P=0.499) and Phosphate (0.061, P=0.506) were obtained. The level of serum PTH in the patients with and without coronary artery disease were 21.8±11.6 pg/dl, 23.2±11.5 pg/dl (P=0.427) respectively.
Conclusion: Our study showed association between CACS and CAD that was statistically significant while no relationship was found between PTH, CACS and CAD.

Abstract
Background: Acquired paralysis of the diaphragm is a condition caused by trauma, surgical injuries, (lung cancer surgery, esophageal surgery, cardiac surgery, thoracic surgery), and is sometimes of an unknown etiology. It can lead to dyspnea and can affect ventilatory function and patients activity. Diaphragmatic plication is a treatment method which decreases inconsistent function of diaphragm. The aim of this study is to evaluate the outcome of diaphragmatic plication in patients with acquired unilateral non-malignant diaphragmatic paralysis. Methods: From 1991 to 2011, 20 patients with acquired unilateral diaphragmatic paralysis who underwent surgery enrolled in our study in Ghaem Hospital Mashhad University of Medical Science. Patients were evaluated in terms of age, sex, BMI, clinical symptoms, dyspnea score (DS), etiology of paralysis, diagnostic methods, respiratory function tests and complication of surgery. Some tests including dyspnea score were carried out again six months after surgery. We evaluated patients with SPSS version 11.5 and Paired t-test or nonparametric equivalent. Results: Twenty patients enrolled in our study. 14 were male and 6 were female. The mean age was 58 years and the average time interval between diagnosis to surgical treatment was 38.3 months. Acquired diaphragmatic paralysis was mostly caused by trauma (in 11 patients) and almost occurred on the left side (in 15 patients). Diagnostic methods included chest x-ray, CT scan, ultrasonography and sniff. Test prior to surgery the average FVC was 41.4±7 percent and the average FEV1 was 52.4±6 percent and after surgery they were 80.1±8.6 percent and 74.4±1 percent respectively. The average increase in FEV1 and FVC 63.4±4, 61.1±7.8. Performing surgery also leads to a noticeable improvement in dyspnea score in our study. Conclusion: In patients with acquired unilateral non-malignant diaphragm paralysis diaphragmatic plication is highly recommended due to the remarkable improvement in respiratory function tests and dyspnea score without mortality and acceptable morbidity.

Volume 71, Issue 11 (2-2014)
Abstract
Background: Genu valgum deformity is exaggerated valgus alignment of lower extremity mechanical axis in knee with a joint line that slopes superolaterally and is corrected by distal femoral osteotomy. In this study the results of treatment and satisfaction in patients with genu valgum were evaluated according to knee society score (KSS) and changes in pre-operation and post-operation lower extremity mechanical axis were compared to each other. Methods: The present study is a cross-sectional study that was performed on 27 patients (30 knees) who have had distal femoral varus osteotomies between 2005 to 2011. Patient’s data were collected from hospital documents, pre-operation and post-operation alignment views and physical exams of operated patients. Radiographs were from the lower extremities and including three joints of hip, knee and ankle (alignment view). Mechanical axis of femur and tibia were drown and they were compared to each other. For measuring patient satisfaction, KSS score was used. All data was collected and evaluated by SPSS 16 software. Results: In this study, 30 knees (in 27 patients) by mean of 30.7±3.36 months follow- up, (range, 5-76 months) were evaluated. The mean of ages in patients was 19.66±4.35, (range 10-34 years). Ten cases (37%) of valgus were on the right side and 14 cases (52%) on the left side and three (11%) cases were reported on both sides. Based on Student’s t-test, there was a significant difference in post- operation lower extremity mechanical axis. The mean of KSS score was 82.52 and the score was defined as 60.7% excellent, 25.1% good, 7.1% fair, and 7.1% poor in patients. According to the results of study, in five patients were non-::::union:::: and re-operated. Conclusion: Distal femoral varus osteotomy is a reliable procedure in knees with valgus correction. This procedure with precise selection of patients, have acceptable end results.

Volume 71, Issue 11 (2-2014)
Abstract
Background: Although a few studies have shown the positive correlation between patients’ serum concentration of 25 OH-Vitamin D3 and type II diabetes mellitus, metabolic syndrome, and insulin resistance, there are controversies regarding the relationship between 25 OH-Vitamin D3 as a risk factor for cardiovascular atherosclerotic diseases that has to be cleared. The aim of this study was to evaluate the association between the rate of 25 OH-Vitamin D3 and the presence and severity of coronary artery disease (CAD) in Patients with suspected CAD. Methods: This study was a cross sectional study that has been conducted in the department of cardiology in Imam Khomeini Hospital complex in collaboration with endocrinology research center. In this study 178 patients with suspected coronary artery disease (CAD) were enrolled. Based on their history and clinical findings coronary angiography was performed in all patients. Severity of CAD has been assessed by using Gensini score, based on their coronary angiography findings. The relationship between severity of CAD and their serum level of 25 OH-Vitamin D3 was evaluated. Serum level of 25OH- Vitamin D3 was measured by the enzyme-linked immunosorbent assay (ELISA) method by Euroimmiune kits (from Germany). Results: Of 178 patients, 50 (28.1%) were female and 128 (71.9%) were male. Mean±SD of their ages was 56.2±11.8 years old. Significant coronary artery stenosis (stenosis more than 50% luminal diameter) was observed in 91 (51.1%) of patients. Mean±SD of serum level of vitamin D3 in patients with CAD was 45±35 nm/l and in patients without CAD was 55±44 nm/l (P= 0.047). Mean±SD of Gensini score was 26.3±21.1, as well. Therefore correlation coefficient between 25 OH-Vitamin D3 and Gensini score was -0.262 (P= 0.043). Conclusion: Although there is a trend toward association between deficiencies of 25 OH-Vitamin D3 and the presence of CAD but their association is not statistically significant. For achieving more convincing findings larger studies are needed.

Volume 72, Issue 10 (1-2015)
Abstract
Background: Short-stem prosthesis for total hip arthroplasty (THA) have been designed to overcome the weakness of standard-stem prostheses and improve surgical outcomes. The aim of this study was to compare short-stem with standard-stem prosthesis outcomes. Methods: This study was performed as a randomized clinical trial. Subjects were selected among patients referred to Sina University Hospital, Tehran, Iran from April 2010 to 2012. THA were performed with short-stem or standard-stem prostheses after obtaining written informed consent from patients. Balanced block randomization method was used to get a random sample in each group. Clinical outcomes were evaluated based on Harris Hip Score (HHS). Patients were followed up for at least one year. All patients were examined at 2 weeks, 6 weeks, 3 months, 6 months and one year after surgery. In each visit, Control X-ray was obtained and bone and prosthetic position were assessed. Also, the symptoms such as infection, pain, claudication, ability to climb stairs, using crutches and weight bearing were rechecked. Student t-test was used to compare outcomes in the two groups. Results: A total of eighty four THA were studied. 13 patients were lost to follow-up or had infection and failure. One patient died with the prosthesis in situ from causes not related to the surgery. Therefore, a total of 70 patients were analyzed. Of these, 34 and 36 hips underwent small stem and standard stem THA, respectively. The mean age of the patients at the time of operation was 61.1±8.68 years (range, 48-86 years). Most common reasons for arthroplasty were osteoarthritis, avascular necrosis and dysplasia of hip. There were significant differences between the two study groups in bleeding during surgery (P=0.001). There were no significant differences among the study groups in HHS except for 6th week and 3th month (P=0.000). Conclusion: The use of short-stem prosthesis can improve the performance of patients in short-term but no significant difference with standard-stem prosthesis in long- term.

Volume 74, Issue 7 (10-2016)
Abstract

Background: The ability to recognize the severity of the disease in those who their survival depend entirely on admission to the intensive care unit, is very valuable clinically. This study aimed to evaluate the clinical effectiveness of modified sequential organ failure assessment (MSOFA) scale to predict mortality and length of stay in intensive care unit patients respectively.

Methods: This was a retrospective cross-sectional study conducted on hospital records of patients admitted to the intensive care unit. All patients’ records who admitted to the intensive care unit of Kowsar Hospital, Semnan city (the capital of the province), Iran, in 2015 considered as the sample. Collecting data were done during 4 weeks in April and May 2016. The data collection tool was a demographic questionnaire and modified sequential organ failure assessment scale. Exclusion criteria included discharge in the first 24 hours after admission, the patient died a few hours after admission and incomplete information to complete the modified sequential organ failure assessment form.

Results: The study of 105 patients' records of the intensive care unit showed that 45.7% of patients were died, 15.2% and 39% were discharged and moved to other wards respectively. The results of logistic regression analysis and receiver operating characteristic (ROC) curve showed that this criterion had moderate sensitivity and specificity for prediction of mortality and length of stay in ICU patients (Area=0.635, CI= 0.527-0.743) and each unit increase in modified sequential organ failure assessment score is accompanied by increasing 32 percent chance of death (OR=1.325; 95% CI:1.129,1.555; P= 0.001(. Also each unit increase in modified sequential organ failure assessment (MSOFA) score accompanied by increasing 19% length of stay in ICU (OR=1.191; 95% CI: 1.034, 1.371; P= 0.015(.

Conclusion: The results of this study showed that the modified sequential organ failure assessment scale is not useful tool to predict the length of stay and mortality of patients admitted to the intensive care unit.

Volume 76, Issue 10 (1-2019)
Abstract
Background: Genital warts are one of the most common sexually transmitted infections, 1% of sexually active population have anogenital warts (AGWs). According to previous studies, the disease affects people's quality of life and imposes financial costs on health systems.
Methods: The present study is a case-control study at spring of 2018. The quality of life of 65 patients with anogenital warts that were referred to Boali-sina Hospital in Sari, Iran compared with 65 control subjects. The World Health Organization Quality of Life Brief (WHOQOL-BREF) questionnaires was used.
Results: According to the results, among the patients with anogenital warts, the quality of sexual contact in majority them were not affected by the disease (70%). The total cost of treatment was less than the monthly income of the family until the time of participating in the study (92%). There was no significant difference between the mean and standard deviation of physical health scores and mental health scores in the control and patient groups. (Respectively P=0.14, P=0.93). There was no significant relationship between the mean of physical health scores with disease severity. However, there was a significant difference between the mental health score in the two groups of patients with low and high levels of severity (P=0.01). Physical health scores in the whole sample have a significant relationship with gender, so that, in women, physical health score was lower than that of male, but the mean score of mental health in both male and female patients was not significantly different (P=0.18). In the control group the score of mental health was lower in women (P=0.041).
Conclusion: In patients with anogenital wart, quality of life doesn’t change significantly, although, mental health scores directly related with disease severity.

Abstract
Background: Prostate cancer has been reported as a worldwide important kind of cancer and the second most common cause of cancer-related mortality among men. Prostate-specific antigen (PSA) serum level is one of the most important markers of prostate cancer diagnosis. While PSA level helps predict the risk of prostate cancer development, researchers still looking for ways to increase the accuracy of prognostic models. To increase the specificity of PSA and decrease of unnecessary biopsies and morbidity, PSA-related parameters such as PSA doubling time (PSADT) have been used. In this study, the relationship between this factor and the severity of prostate cancer was evaluated.
Methods: In this retrospective study, the data of patients who were subjected to transrectal ultrasound-guided (TRUS) biopsy of the prostate and referred to Imam Khomeini Hospital, Tehran, between 2009 and 2017 were reviewed. We enrolled the men with at least two consecutive elevated PSA level within three months to calculate PSADT. Based on the pathology report, primary and secondary Gleason score (GS) were determined. Correspondingly, considering GS, the patients were divided into two groups with high-grade and low-grade tumor (GS<7 considered as low-grade and GS>7 considered as high-grade tumor).
Results: Totally, 1712 cases of TRUS biopsy of the prostate were studied. Among them, 547 (32.3%) had prostate cancer, of whom 73 cases were eligible based on inclusion criteria and were consented to enroll in the study. According to the data obtained, we found a significant difference in PSADT between the two groups of patients with high-grade and low-grade malignancy (mean±SD PSADT, 9.8±14.2 vs. 16.1±14.9 respectively, P=0.004). Considering the seven months as the cut-off point for PSADT in determining malignancy, there was a significant difference between the two groups according to Fisher's exact test (P=0.01).
Conclusion: In our study, PSADT cut-off of 7 months provided the greatest accuracy for differentiation between low-grade and high-grade malignancy, and PSADT has acceptable accuracy for the diagnosis of high-grade tumors.

Abstract
Background: Opioid poisoning is the most common type of poisoning in intensive care units (ICUs). This group usually includes patients who have been drug abusers for a long time and now require hospitalization either because of acute overdose or due to side effects of routine opioid use. This study aimed to compare the severity and prognosis of patients using common mortality predictors Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score (SAPS II), Acute Physiology And Chronic Health Evaluation (APACHE II, APACHE IV) on different days of hospitalization.
Methods: This cross-sectional study was performed on all patients with opioid poisoning admitted to the ICU, Imam Reza Hospital, Mashhad, Iran, from the beginning of April 2016 to March 2017 (Persian Calendar). For all poisoned patients enrolled in the study, the four mortality predicting tools were filled daily in the first three days of hospitalization and then every other day until discharge from the ICU or patient's death.
Results: Overall, 57 patients were evaluated of whom 72% (41 patients) were male. The mean age was 49.9±19.8 (median 53, range 18-94) years. The mean length of stay in the ICU was 13.5±17.5 (median 7, range: 75-75) days. The mortality rate was 17.5% (10 patients). The scores of SOFA, SAPS II, APACHE II, and APACHE IV were significantly higher in deceased patients than in discharged ones. The highest diagnostic accuracy (area under the curve) for all four predicting tools was observed in the second week of hospitalization. On the other hand, SAPS II (74%) on the first day, APACHE-II (76%) on the second day, APACHE-II (82%) on the third day, SOFA (77%) on day 4-5, and SAPS II (82%) on day 6-7 had the highest diagnostic accuracy.
Conclusion: In the present study scores of all four mortality predicting tools at admission were significantly associated with mortality. The accuracy of SAPS II, APACHE IV, and APACHE II are appropriate for estimating prognosis, especially after the second week of admission.

Abstract
Background: Multiple Sclerosis (MS) is one of the most debilitating disease among young adults. Understanding the disability score (Expanded Disability Status Scale (EDSS)) of these patients is helpful in choosing their treatment process. Calculating EDSS takes a lot of time for Neurologists, so having a way to estimate EDSS can be helpful. This study aimed to estimate the EDSS score of MS patients using statistical models including Artificial Neural Network (ANN) and Decision Tree (DT) models.
Methods: This cross-sectional study was performed on MS registry study data of Kermanshah province from April 2017 to November 2018. From the total data available in the registry system, The 12 variables including demographic information, information about MS disease and their EDSS score were extracted. EDSS scores were also estimated using ANN and DT models. The performance of the models was compared in terms of estimation error, correlation and mean of an estimated score. Data were analyzed using Weka software version 3.9.2 and SPSS software version 25 with a significance level of 0.05.
Results: In this study, 353 people were studied. The mean age of the patients was 36.47±9.1 years, the mean age of onset was 9.2±30.34 years, the mean duration of the disease was 6.20±5.7 years and the mean EDSS score was 2.46±1.8. Estimation errors in the DT model were lower than in the ANN model. The real EDSS score was significantly correlated with scores estimated by DT (r=0.571) and ANN (r=0.623). The mean EDSS estimated by the DT model (2.46±1.1) was not significantly different from the real EDSS mean (P=0.621) but the mean EDSS estimated by the ANN model (2.87±1.3) was significantly higher than the real EDSS mean. (P<0.05).
Conclusion: The DT model could better estimate the EDSS score of MS patients than the ANN model and made predictions that were closer to the actual EDSS scores. Therefore, the DT model can accurately estimate the EDSS score of MS patients.

Abstract
Background: Prostate cancer is the most common malignancy in men and the second leading cause of death in all countries of the world. The exact mechanism of prostate cancer is not known. On the other hand, early detection of prostate cancer can lead to a complete cure. Several clinical experiments including Digital Rectum Examination (DRE), biochemistry such as Prostate Specific Antigen (PSA), and pathology such as Trans Rectal Ultra Sonography (TRUS) are used to assess the size and spread of prostate cancer. In this study, the relationship between mean serum PSA and Gleason score as a standard method in patients with prostate cancer was compared using the parameters extracted from DCE MRI.
Methods: This applied-fundamental study was performed on 90 patients with prostate cancer, according to McDonald's criteria who were referred to Shafa Imaging Center in Isfahan, from March 2020 to October 2020. Quantitative analysis is based on modeling the change of concentration of the contrast agent using pharmacokinetic modeling techniques. The pathologist then determined the Gleason score using anatomical landmarks (such as prostate urethra) in the same areas suspected of being cancerous. Existing commercial software captures DCE-MRI data and creates parametric maps such as Ktrans and Kep maps that can be used for diagnostic purposes.
Results: Kep and Ktrans maps showed a significant difference between healthy and cancerous tissue. Kep and Ktrans in prostate cancer were significantly higher than in healthy tissue (P<0.05). Pearson correlation coefficient was used to investigate the relationship between DCE-MRI parameters and histopathological findings. No significant relationship was observed between Gleason score and DCE MRI parameters.
Conclusion: DCE MRI parameters significantly improve the accurate diagnosis of prostate cancer and are useful and effective for diagnosis, management, and evaluation of men with prostate cancer, but should not be considered as a substitute for tissue biopsy.
