Abstract
The Latin word lupus, meaning wolf, was in the medical literature prior to the 1200s to describe skin lesions that devour flesh, and the resources available to physicians to help people were limited. The present text reviews the ethnobotanical and pharmacological aspects of medicinal plants and purified molecules from natural sources with efficacy against lupus conditions. Among these molecules are artemisinin and its derivatives, antroquinonol, baicalin, curcumin, emodin, mangiferin, salvianolic acid A, triptolide, the total glycosides of paeony (TGP), and other supplements such as fatty acids and vitamins. In addition, medicinal plants, herbal remedies, mushrooms, and fungi that have been investigated for their effects on different lupus conditions through clinical trials, in vivo, in vitro, or in silico studies are reviewed. A special emphasis was placed on clinical trials, active phytochemicals, and their mechanisms of action. This review can be helpful for researchers in designing new goal-oriented studies. It can also help practitioners gain insight into recent updates on supplements that might help patients suffering from lupus conditions.

Abstract
Background Reinfection with Coronavirus Diseases 2019 (COVID-19) has raised remarkable public health concerns globally. Therefore, the present retrospective cohort study intended to investigate COVID-19 reinfection in registered patients of Fars province in Iran from February 2020 to April 2021. Methods The patients' data, including the COVID-19 infection, symptoms, comorbidities, and demographics, were collected using the Health Information Systems (HISs). The patients were divided into three groups in terms of the duration between the initial infection and reinfection, including 28-44, 45-89, and more than 90 days. Following the univariate analysis, logistic regression was used to investigate the factors effective on COVID-19 reinfection. Results A total of 213768 patients had a positive Polymerase Chain Reaction (PCR) test. The reinfection rate was 0.97% (2079 patients). Of these re-infected individuals, 14.9%, 18.5%, and 66.6% had their second positive test 28-45, 45-89, and ≥90 days later, respectively. The mean duration between the initial infection and reinfection was 130.56 days (29-370 days). The chance of reinfection was significantly higher in the youths (Odds Ratio (OR)=2.055; P<0.001), men (OR=1.283; P<0.001), urban population (OR=1.313; P<0.001), and healthcare providers (OR=4.453; P<0.001). The patients with chronic pulmonary diseases, chronic kidney diseases, and malignancy were 1.421 (P=0.036), 2.239 (P<0.001), and 3.437 (P<0.001) times, respectively, more likely prone to reinfection. Conclusion The results of this study showed that there is a higher risk of reinfection in several vulnerable groups including healthcare providers, young individuals, residents of urban areas, men, and individuals with underlying diseases.

Abstract
OBJECTIVES Numerous studies have shown the pharmacological effects of pomegranate, such as: anti-cancer, cholesterol-lowering, anti-diabetic, and antihypertensive features. Pomegranate consumption has also revealed some adverse effects. This systematic review aimed to explore the adverse effects of pomegranate reported in clinical studies. CONTENT The keywords "pomegranate", "Punica granatum", "side effect", "clinical trial", and "case report or case series" were searched for in valid databases. Reports about adverse effects of pomegranate were also collected from several international registries. SUMMARY This systematic review included a total of 66 clinical articles. Eleven articles have reported side effects of pomegranate. Twenty-one articles have recorded no side effects in the pomegranate group while 34 articles have not mentioned any side effects for this plant. The study also included 7 case report studies. The most common side effects included gastrointestinal problems, flu-like symptoms, and urinary problems. In case report studies, the most significant reported side effect was allergic reaction. OUTLOOK In summary, pomegranate and its extract seem to be safe according to the reported adverse effects. Meanwhile, conducting more robust controlled trials with pomegranate products and documentation of any probable side effect is warranted.

Abstract
OBJECTIVE Coronavirus disease 2019 (COVID-19) is a debilitating disease with numerous medical and non-medical consequences. Our study aimed to evaluate the efficacy of Persian barley water in controlling the clinical outcomes of hospitalized COVID-19 patients. PATIENTS AND METHODS This was a single-blind, add-on therapy, randomized controlled clinical trial conducted in Shiraz, Iran, from January to March 2021. One hundred hospitalized COVID-19 patients with moderate disease severity were randomly allocated to receive routine treatment (per local protocols) with or without 250 ml of Persian barley water (PBW) daily for two weeks. Clinical outcomes and blood tests were recorded before and after the study period. Multivariable modeling was applied using Stata software for data analysis. RESULTS The PBW product passed our standardization and safety assessments. Length of hospital stay (LHS) was 4.5 days shorter in the intervention group than the control group regardless of history of cigarette smoking (95% confidence interval: -7.22, -1.79 days). Also, body temperature, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and creatinine significantly dropped in the intervention group compared to the control group. No adverse events related to PBW occurred. CONCLUSIONS This clinical trial demonstrated the efficacy of PBW in minimizing the LHS, fever, and levels of ESR, CRP, and creatinine among hospitalized COVID-19 patients with moderate disease severity. More robust trials can help find safe and effective herbal formulations as treatments for COVID-19.

Abstract
Primary hypothyroidism is a common disease. Some patients have persistent symptoms despite normal serum thyroid-stimulating hormone (TSH) levels. Ginger is reported to be beneficial in relieving similar symptoms. Our aim was to evaluate the efficacy of ginger supplementation in relieving persistent symptoms in these patients. In this randomized, double-blind, placebo-controlled clinical trial, 60 hypothyroid patients aged 20-60 years with normal serum TSH concentrations were randomly allocated to two equal parallel study groups of ginger (500 mg twice a day) or placebo for 30 days. Hypothyroid symptoms were evaluated as the primary outcome using the Thyroid Symptom Rating Questionnaire (ThySRQ) before and after the intervention. Anthropometric measures and laboratory indices including TSH, triglyceride (TG), total cholesterol (TChol), and fasting blood sugar (FBS) were considered as secondary outcomes. A significant lower mean total ThySRQ score (8.63 ± 5.47 vs. 15.76 ± 6.09, P < 0.001) was observed in the ginger group compared to the control group. Ginger led to significant improvements in the mean scores of the weight gain, cold intolerance, constipation, dry skin, appetite, memory loss, concentration disturbance, and feeling giddy or dizzy domains (P < 0.001). However, no significant improvements were observed in hair loss, nail fragility, hearing, hoarseness, speech, and depression or feeling down (P > 0.05). Ginger supplementation also led to a significant decrease in body weight, body mass index, waist circumference, serum TSH, FBS, TG, and TChol levels compared to the placebo. In summary according to preliminary results of this study, ginger supplementation can help relieve persistent hypothyroid symptoms. Also, it may have beneficial effects in terms of weight reduction and regulation of the FBS and lipid profile in hypothyroid patients.

Abstract
Purpose This study aimed to assess incidental abnormal findings in the paranasal sinuses and anatomical variations of the ostiomeatal complex (OMC) on magnetic resonance imaging (MRI) scans. Materials and Methods MRI scans of 616 patients (mean age, 44.0±19.4 years) were evaluated. Prior to obtaining the MRI scans, a checklist of patients’ clinical symptoms was filled out after obtaining their consent. The Lund-Mackay classification was used to assess the paranasal sinuses and OMC. The prevalence of abnormal findings and their associations with patients’ age, sex, and subjective symptoms were analyzed by the chi-square test, independent-sample t-test, and analysis of variance. The level of significance was set at 0.05. Results Abnormal findings in the paranasal sinuses were detected in 32.0% of patients, with a significantly higher prevalence in males (P<0.05), but no significant association with age (P>0.05). Epithelial thickening and retention cyst were the most common abnormal findings in the paranasal sinuses. According to the Lund-Mackay classification, 93% of the study population had normal sinuses (score<4). Concha bullosa and paradoxical concha were detected in 15.3% and 3.4%, respectively, with no significant association with the presence of septal deviation or Lund-Mackay classification (P>0.05). Conclusion Considering the relatively high prevalence of abnormal findings in the paranasal sinuses, it appears that clinical symptoms alone are not sufficient to diagnose sinusitis. A more accurate strategy would be to assess radiographic images of the paranasal sinuses and use a classification system. Sinusitis should be suspected in patients receiving a high score in this classification.

Abstract
PURPOSE To compare a zoomed EPI-DWI (z-EPI) with a standard EPI-DWI (s-EPI) in the primary diagnostics of rectal cancer and assess its potential of reduced image artifacts. METHOD 22 therapy-naïve patients with rectal cancer underwent rectal MRI at a 3 T-system. The protocols consisted of a z-EPI DWI and s-EPI DWI sequence. Images were assessed by two independent and experienced readers regarding overall image quality and artifacts on a 5-point Likert scale, as well as overall sequence preference. In a lesion-based analysis, tumor and lymph node detection were rated on a 4-point Likert scale. Apparent diffusion coefficient (ADC) measurements were performed. RESULTS Overall Image quality score for z-EPI and s-EPI showed no statistically significant differences (p = 0.80/0.54, reader 1/2) with a median score of 4 ("good" image quality) for both sequences. The image quality preference rank for z-EPI and s-EPI was given the category 'no preference' in 64 % (reader 1) and 50 % (reader 2). Most artifact-related scores (susceptibility, motion and distortion) did not show reproducible significant differences between z-EPI and s-EPI. The two sequences exhibited comparable, mostly good and excellent quality scores for tumor and lymph node detection (p = 0.19-0.99). ADC values were significantly lower for z-EPI than for s-EPI (p = 0.001/0.002, reader 1/2) with good agreement of ADC measurements between both readers. CONCLUSION Our data showed comparable image quality and lesion detection for the z-EPI and the s-EPI sequence in MRI of rectal cancer, whereas the mean ADC of the tumor was significantly lower in z-EPI compared to s-EPI.

Abstract
Background:
Crown lengthening surgery is one of the most common periodontal surgeries. The analgesic effects of benzydamine and ibuprofen tablets have been proven in various studies. The purpose of this study was to compare benzydamine hydrochloride mouthwash 0.15% with ibuprofen in decreasing the pain of patients with crown lengthening surgery who had referred to the Periodontology Department of Yazd Dentistry School in 2015.
Materials & Methods:
In this clinical trial study, 36 patients aged 30 to 60 years who referred to the Periodontal Department of the Dental Faculty of Yazd University of Medical Sciences needing a crown lengthening surgery were randomly allocated to two groups. The patients of the first group were asked to wash their mouth using benzydamine hydrochloride mouthwash 0.15% after the surgery according to the instructed protocol and the patients in the second group were asked to take an ibuprofen tablet (400 mg) every 6 hours. After 24 hours, the level of pain was measured by using the numerical criteria of the Visual Analog Scale (VAS) and the data were analyzed using SPSS software version 18. T test and Mann-Whitney test were used as appropriate.
Results:
77.8% of the participants in the first group had mild pain and rest of the participants had moderate pain. 77.8% of the participants who used ibuprofen tablet reported mild pain, 16.7% had moderate pain and 5.6% had severe pain. The results did not illustrate more effect of ibuprofen on the reduction of pain after crown lengthening surgery compared with benzydamine hydrochloride 0.15% (P=0.48).
Conclusion:
In the present study, there were no changes in the VAS index between the two groups. Therefore, in order to decrease pain after periodontal surgery, benzydamine hydrochloride mouthwash can be widely used as it has fewer side effects, lower price, and similar effects with ibuprofen.

Abstract
BACKGROUND Free gingival graft is the most commonly practiced predictable technique for gingival augmentation. OBJECTIVE To assess the effectiveness of human amniotic membrane, a biological dressing, on wound healing and post-operative pain after its application on the palatal donor site after free gingival graft surgery. METHODS Of 27 eligible patients, 15 were randomized into a test group and received human amniotic membrane dressing sutured over their palatal donor site; 12 were randomized into a control group in whom the palatal donor site was only sutured. Standard clinical photographs were taken at 7, 14, and 21 days post-operatively and evaluated by 3 periodontists. The pain score at the donor site was assessed by a visual analog score; the number of analgesics taken was also recorded. RESULTS The mean color match scores were higher in the test group than the control group at 14 (p<0.01) and 21 days after surgery (p=0.02). The difference in tissue texture (p=0.01) and inflammation (p=0.02) between the two groups was only significant on day 14 (p<0.05). The pattern of pain relief was better in the test group compared with the control group, especially in first days, although the differences were not significant in terms of the number of analgesics taken or the pain score. CONCLUSION Application of human amniotic membrane can accelerate wound healing and may decrease post-operative pain and discomfort by a limited amount.

Background Ulcerative colitis is the most common form of inflammatory bowel disease worldwide, which presents with superficial ulcers in the rectum and colon. The aim of this study was to assess the effectiveness of rose oil soft capsules over placebo on the clinical outcomes in moderate to severe ulcerative colitis. Materials and Methods This study was a pilot randomized, double-blind clinical trial, and the 40 patients were assigned into rose oil and placebo groups (n=20 per group). All patients were instructed to use their prescribed two soft capsules three times daily for two months. The clinical symptoms, quality of life the patients, and calprotectin level were evaluated via partial Mayo clinic score, irritable bowel disease questionnaire (IBDQ-9), and calprotectin kit as primary outcome measures. Results The mean age of the participants was 41±10 years. Most of them (53.6%) were male, and the remaining (46.4%) were female. The demographic and baseline data showed no differences between the two groups. Partial Mayo clinic scores decreased in both groups after the treatment, but the difference between the rose oil and placebo groups was not statistically significant (P=0.99). IBDQ-9 score also increased in both interventions before and after the treatment (P=0.012), though the differences between these two groups were not statistically significant (P=0.61). There were no significant differences between the two study groups either in terms of calprotectin level (P=0.219). Conclusion This study showed that rose oil might improve ulcerative colitis clinical outcomes, but for a better evaluation, it is imperative to conduct experiments with a large sample size and longer follow-up observation.

Abstract
Several dermal products have been introduced to substitute dermal tissues. In this study we review the effects of these products on repairing third-degree burn wounds and managing complications in animal specimens. Using an interventional approach, rats were randomly assigned to four groups (G1 to G4). Two wounds were created on the back of each rat. An open wound was left on the back of rats in G1; in G2, wounds were covered with a thick rat derived-ADM product and overlying thin skin graft; on G3 rats, similar third degree ulcers were made with one ulcer covered with harvested thin skin graft. In G4, ulcers were covered with a thin rat derived-ADM product and thin graft. Factors such as take rate, histopathological score, wound contracture and graft contracture were compared on the 7th, 15th, 21st and 30th day. Mean graft take rate on the 30th day in the thick ADM, thin ADM and graft group showed a significant difference (p=0.015). Histopathological score on the 30th day in the thin ADM, thick ADM and graft group showed no considerable difference. Mean graft take rate was significantly better in the thin ADM and graft group than in the thick ADM group. Wound contracture was significantly more severe in the thick ADM and control group than in the thin ADM and graft group.

Abstract
The aim of this study was to evaluate an engineered nanostructure to silence five important oncogenes, including BAG1, MDM2, Bcl-2, BIRC5 (survivin) and XIAP, in acute myeloid leukemia subtype 2 (AML-M2). The smart nanostructures were functionalized gold nanoparticles (FGNs) containing five antisense oligonucleotides (AOs) and one anti-CD33(+)/CD34(+) aptamer. First, the best AO for each gene was selected with the OligoWalk online software, and then different arrangements of AOs were evaluated with the RNAstructure software. Thereafter, naked gold nanoparticles (NGNs) were synthesized by the reaction of 1000 mm HAuCl4 with 10 μg ml(-1) ascorbic acid. Next, five AOs and one anti-CD33(+)/CD34(+) aptamer were attached to NGNs through serial reactions. Later, 5 ml of heparinized blood samples from five AML-M2 patients were prepared, cancerous cells were isolated and then incubated with three concentrations (75, 150 and 300 μg ml(-1)) each of FGNs, NGNs, gold nanoparticles functionalized with scrambled oligonucleotides (GNFSONs) and doxorubicin. Finally, cell death percentage and gene expressions were measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and real-time PCR, respectively. This study showed that FGNs and doxorubicin led to more cell death compared with NGNs and GNFSONs (P<0.05). Interestingly, all concentrations of FGNs led to a decrease in gene expression. As an important finding, although all concentrations of doxorubicin could also inhibit the expression of genes, FGNs had more effect (P<0.05). Moreover, both NGNs and GNFSONs could silence all genes only at a concentration of 300 μg ml(-1). For BCL2 and XIAP, a dose-dependent pattern was observed, but there was no similar pattern for others.

Abstract
Prophylactic gastropexy is a procedure that prevents the occurrence of a life threatening condition known as gastric dilation and volvulus (GDV) in dogs. The objective of this study was to compare incisional, belt loop and minimally invasive endoscopically assisted gastropexy by evaluating different parameters such as surgical time, length of scar and score of pain in dogs. Twenty-one healthy, mixed-breed adult dogs weighting 14.3 ± 2.6 kg were randomly divided into three groups. Three gastropexy techniques applied in the following order: incisional (group I), belt loop (group B), and endoscopically assisted gastropexy (group E). Surgical time, anesthetic time, length of surgical incision and score of pain 3 h after surgery were recorded for all dogs. Two weeks after the surgery, positive-contrast gastrography was used to evaluate stomach position and total gastric emptying time. Ultrasonography was also used to evaluate the gastropexy two months after the surgery. Adhesion was confirmed two months after the surgery between the stomach wall at the pyloric antrum and the right side of the body wall in all dogs by ultrasound. The mean surgical time, length of surgical incision and score of pain were significantly lower in group E compared to group I and B (P<0.05). No significant differences were found in total gastric emptying time and gastropexy thickness post-operatively (P>0.05). Due to advantages observed in the current study, the endoscopically assisted technique seems to be a suitable alternative to open incisional and belt loop gastropexies for performing prophylactic gastropexy, especially when performed by skilled surgeons.

Abstract
BACKGROUND The present study is a utilization review of outpatient services offered by specialists and underlying social factors among urban families in Fars Province, Iran. METHODS The present study conducted among 1900 residents in urban areas of Fars Province in January 2013. Sampling was carried out through a three-step method, which was designed based on utilization of health services survey. Data were analyzed using statistical tests. RESULTS About a quarter of the sample group expressed the need for outpatient services of specialists, of whom about 83% received medical attention of a specialist. Among the main reasons for not referring to specialists were financial issues as the top reason followed by refusal to visit the physician, long distances and high costs of the services. CONCLUSION About 17% of the participants who needed outpatient services of specialists failed to receive the service. This indicates the necessity of measurements to improve the access to outpatient services of specialists among different social groups.

Abstract
BACKGROUND Interleukins are a group of cytokines responsible for regulating inflammatory and infectious responses. Interleukin-8 plays an important role in chemotaxis and functioning of leukocytes and is locally produced in infected tissues; it is seen in abundance in the urine of individuals with Urinary Tract Infection. MATERIAL & METHODS Midstream sterile urine sampling was performed in different patients admitted to the Spinal Cord Injury (SCI) research center. The samples were tested to determine the level of IL-8 through the ELISA method. The commercial kit used for this study was an R & D kit built in Germany. RESULTS The mean level of IL-8 was 369.59 pg/ml and 75.42 pg/ml in male and female patients respectively. Among the 97 patients under study, 87 (89.7%) were IL-8 positive (>10 pg/ml) and 10 patients were IL-8 negative (<10 pg/ml). Among the 87 IL-8 positive subjects, 64 patients had no UTI symptoms, while 23 did. CONCLUSION SCI patients should have their urinary IL-8 levels measured on a routine and periodic basis, irrespective of their SCI severity or the presence or absence of UTI symptoms. The timely and effective diagnosis & treatment of UTI can prevent the irreversible complications caused by frequent UTI and resistance to treatment in this group of patients.

Abstract
INTRODUCTION Current risk prediction scoring systems in pancreas transplantation are limited to organ factors and are specific to predicting graft outcome. They do not consider recipient factors or inform regarding recipient morbidity. The aim of this study was to assess the utility of commonly used general surgical risk prediction models (P-POSSUM [Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity], MODS [multiple organ dysfunction score], Charlson co-morbidity index, revised cardiac risk index, ASA [American Society of Anesthesiologists] grade and Waterlow score), and to correlate them with total length of hospital stay (LOS) and critical care unit (CCU) LOS, important surrogate markers of patient outcome. METHODS All risk prediction scores were calculated prospectively for all simultaneous pancreas and kidney (SPK) transplant recipients from November 2011 to October 2013, and correlated with outcome measures. RESULTS Overall, 57 SPK transplant recipients were analysed. The mean age was 42.0 years (standard deviation [SD]: 7.60 years), 27 (52%) were male and the mean body mass index was 25.43kg/m(2) (SD: 3.11kg/m(2)). The mean pancreas and kidney cold ischaemic times were 703 minutes (SD: 182 minutes) and 850 minutes (SD: 192 minutes) respectively. The median total LOS and mean CCU LOS was 17 days (range: 8-79 days) and 7 days (SD: 4.04 days) respectively. When correlated with risk prediction scores, Waterlow score was the only significant predictor of total LOS and CCU LOS (p<0.001 [Spearman's correlation] and p=0.001 [Pearson's correlation] respectively). CONCLUSIONS Preoperative risk prediction plays an important part in planning perioperative care. To date, no validated risk prediction scoring system exists for SPK transplantation. This prospective study indicates that Waterlow score identifies high risk individuals and has value in the prediction of outcome following SPK transplantation.

Abstract
Candida glabrata was thought to be a primarily non-pathogenic organism. However, with the ever-increasing population of immunocompromised individuals, it is considered to be an opportunistic pathogen. Patients with spinal cord injuries often using a long-term urinary catheter and are high risk for Urinary Tract Infections. This case report describes a patient with spinal cord injury (thoracic region) with a pure culture of Candida glabrata in a urine sample.

Abstract
Glandular odontogenic cyst is a newly determined jaw entity with aggressive behavior and a high rate of recurrence. There is histopathologic resemblance to other lesions of the jaw such as intraosseous mucoepidermoid carcinoma. Although enucleation and curettage are not the treatment of choice for this cystic lesion, they comprise the most common method. On the other hand, filling the defect is a controversial matter, especially in lesions with large size. We introduce 4 cases of GOC, of which 2 are cases of recurrence. We applied bone material substitutes in 3 of these cases with success.

Abstract
In this paper, a new fuzzy methodology is developed to optimize water and waste load allocation (WWLA) in rivers under uncertainty. An interactive two-stage stochastic fuzzy programming (ITSFP) method is utilized to handle parameter uncertainties, which are expressed as fuzzy boundary intervals. An iterative linear programming (ILP) is also used for solving the nonlinear optimization model. To accurately consider the impacts of the water and waste load allocation strategies on the river water quality, a calibrated QUAL2Kw model is linked with the WWLA optimization model. The soil, water, atmosphere, and plant (SWAP) simulation model is utilized to determine the quantity and quality of each agricultural return flow. To control pollution loads of agricultural networks, it is assumed that a part of each agricultural return flow can be diverted to an evaporation pond and also another part of it can be stored in a detention pond. In detention ponds, contaminated water is exposed to solar radiation for disinfecting pathogens. Results of applying the proposed methodology to the Dez River system in the southwestern region of Iran illustrate its effectiveness and applicability for water and waste load allocation in rivers. In the planning phase, this methodology can be used for estimating the capacities of return flow diversion system and evaporation and detention ponds.

Abstract
In this paper, a new methodology is developed to handle parameter and input uncertainties in water and waste load allocation (WWLA) in rivers by using factorial interval optimization and the Soil, Water, Atmosphere, and Plant (SWAP) simulation model. A fractional factorial analysis is utilized to provide detailed effects of uncertain parameters and their interaction on the optimization model outputs. The number of required optimizations in a fractional factorial analysis can be much less than a complete sensitivity analysis. The most important uncertain inputs and parameters can be also selected using a fractional factorial analysis. The uncertainty of the selected inputs and parameters should be incorporated real time water and waste load allocation. The proposed methodology utilizes the SWAP simulation model to estimate the quantity and quality of each agricultural return flow based on the allocated water quantity and quality. In order to control the pollution loads of agricultural dischargers, it is assumed that a part of their return flows can be diverted to evaporation ponds. Results of applying the methodology to the Dez River system in the southwestern part of Iran show its effectiveness and applicability for simultaneous water and waste load allocation in rivers. It is shown that in our case study, the number of required optimizations in the fractional factorial analysis can be reduced from 64 to 16. Analysis of the interactive effects of uncertainties indicates that in a low flow condition, the upstream water quality would have a significant effect on the total benefit of the system.

Abstract
BACKGROUND The true extent of Methicillin-Resistant Staphylococcus aureus (MRSA) colonization and incidence of infection after solid organ transplantation in adults and children is not well-known. The aim of this study was to evaluate the incidence and the outcomes of MRSA infection following kidney and/or pancreas transplantation. MATERIAL AND METHODS We reviewed the case notes of all patients who developed MRSA colonization and infection within the first year of transplantation between September 2002 and December 2009. The primary endpoint of this study was mortality. The secondary endpoints included morbidity, graft failure, and length of hospital stay. RESULTS During the study period 1116 transplantations were performed. MRSA colonization was detected in 14 patients (1.25%) and infection occurred in 6 cases (0.53%) post-transplantation. Graft failure was not associated with MRSA colonization/infection in any of the cases. The mortality rate attributed to MRSA was 10% (n = 2). The overall median length of stay was 16 days (range, 6-243 days). CONCLUSIONS Our study demonstrates that the prevalence of MRSA colonization and infection in our unit is low in spite of immunosuppression. The incidence of MRSA infection was higher among patients who underwent pancreas transplantation. Patients who had MRSA colonization and then developed infection had higher morbidity and mortality rates.

Abstract
BACKGROUND Chronic renal failure and hemodialysis affect many ECG parameters which can affect cardiac repolarization. OBJECTIVE To investigate the change in ventricular repolarization before and after kidney transplantation in children. METHODS A total of 45 children with end-stage renal disease, 45 children at least 6 months after successful renal transplantation, and 45 normal age-matched subjects were enrolled into this study. A 12-lead ECG was recorded in the 3 groups. QT dispersion, QTc dispersion, and T peak to T end (TPE) dispersion were measured. RESULTS In the patients before and after renal transplantation and the normal children, respectively, the mean±SD QT dispersion was 0.083±0.033, 0.056±0.029, and 0.033±0.016 (p<0.01); the mean±SD QTc dispersion was 0.104±0.038, 0.066±0.033, and 0.039±0.020 (p<0.01); the mean±SD TPE interval dispersion was 0.060±0.021, 0.045±0.021, and 0.034±0.019 (p<0.01). There was a significant correlation between left intra-ventricular diastolic diameter and QT dispersion, QTc dispersion, and TPE dispersion. The systolic velocity of the mitral valve also correlated with TPE dispersion (r=0.44, p=0.01). CONCLUSION In children with chronic renal failure, indices of ventricular repolarization improve after transplantation, though they still remain longer than the normal values.

Abstract
Whole organ vascularized pancreatic transplant is a recognized treatment for diabetes and is increasingly being performed worldwide. The procedure itself is complex and is associated with significant mortality and morbidity. Despite improvements in surgical techniques, postoperative complications of pancreatic transplantation are still common and include graft rejection, pancreatitis, peripancreatic fluid collections, exocrine leaks, vascular thrombosis, and hemorrhage. In this pictorial essay, we review clinical presentation and imaging features of these complications. We also briefly discuss technique and complications of islet cell transplants.

Abstract
Persons with schizophrenia spectrum disorders (SSDs) are not only at risk because of disabling disease symptoms but because necessary medications create health risks associated with high rates of obesity. Despite the well-known benefits of exercise, persons with SSDs rarely adhere to such regimens; few interventions to motivate exercise behavior have been tested in this group.The purpose of this study is to examine effects of the Walk, Address sensations, Learn about exercise, Cue exercise behavior for persons with SSDs (WALC-S) motivational intervention upon exercise behavior. We will recruit a total of eighty outpatients 18-68 years, meeting these criteria: 1) chart diagnosis of schizophrenia, any subtype, schizoaffective disorder or schizophreniform disorder, according to the criteria described in the Diagnostic and Statistical Manual for Mental Disorders, 2) English speaking, 3) Stable medication regimen (defined as no medication changes within the last month), and 4) medical clearance for moderate exercise in writing from primary care provider. Participants will be randomly assigned to the experimental (4-week WALC-S motivational intervention), or the control group (4-week time and attention control). After the first 4 weeks, all participants will attend a 16-week walking group.The primary measures of the effectiveness of the WALC-S are attendance, persistence and compliance to the 16-week walking group. The study will be completed in approximately January 2010. In addition to hypothesis testing, this study will provide information to estimate effect sizes to calculate power and determine appropriate sample sizes for future inquiries. This paper describes the rationale and design of the study.

Abstract
Congenital palatal defects are common in animals but there is only one report of water buffalo has been recorded in Iran. One died male water buffalo calf was examined after hysterotomy operation. At necropsy findings, brachygnathia, palate cleft and small lungs were diagnosed. It is the second report of water buffalo cleft palate in Iran.

Abstract
PURPOSE We performed a randomized, prospective trial to compare the incidence of early urological complications and health care expenditures in renal transplant recipients with or without ureteral stenting. MATERIALS AND METHODS Patients receiving a renal transplant at a single center were randomized preoperatively to undergo Double-J stent or no-stent ureterovesical anastomosis from November 1998 to October 2001. Early urological mechanical complications were recorded, including urinary leakage or obstruction, or urinary tract infections within 3 months of transplantation. Direct health care costs associated with stenting, urological complications and urinary tract infection management were also collected. RESULTS A total of 201 patients were randomized to a stent (112) and a no-stent (89) group. In the no-stent group 11 patients received a stent due to intraoperative findings and were excluded from study. At 3 months there were significantly more cases of urinary leakage (8.9% vs 0.9%, p <0.008) and ureteral obstruction (7.7 % vs 0%, p <0.004) in the no-stent than in the stent group. Mean time of stent removal was 74.3 days. A significant increase in urinary tract infections was observed when stent was left greater than 30 days after transplantation compared to the rate in the no-stent group (p <0.02). An additional cost of 151 UK pounds per patient was incurred in the no-stent group vs the stent group. CONCLUSIONS Using a ureteral stent at renal transplantation significantly decreases the early urinary complications of urine leakage and obstruction. However, there is a significant increase in urinary tract infections, primarily beyond 30 days after transplantation. Stent removal within 4 weeks of insertion appears advisable.

Abstract
To investigate the inactivation of potential pathogens, we evaluated survival rates for Escherichia coli, Enterococcus faecalis, Aeromonas hydrophila and Salmonella typhi in samples taken from the Isfahan drinking water system. Chlorine residual, pH, temperature and total organic carbon levels were measured. The organism most sensitive to chlorine was A. hydrophila. It was inactived in < 100 minutes at chlorine levels of 0.11 mg/L to 0.90 mg/L. The other 3 organisms showed higher resistance. E. coli tolerated 0.30 mg/L chlorine for > 1000 minutes while Ent. faecalis and S. typhi survived at total chlorine concentration of 0.50 mg/L for 100 minutes. We concluded that total chlorine levels of less than 0.71 mg/L in water supply systems cannot provide the recommended safety levels.
