Introduction. Diaper dermatitis (DD) is a common inflammatory disorder among children and infants. The objective of the present randomized and double-blind trial was to compare the therapeutic efficacies of Aloe vera cream and Calendula officinalis ointment on the frequency and severity of DD in children. Methods. Sixty-six infants with DD (aged < 3 years) were randomized to receive either Aloe cream (n = 32) or Calendula ointment (n = 34). Infants were treated with these drugs 3 times a day for 10 days. The severity of dermatitis was graded at baseline as well as at the end of trial using a 5-point scale. The adverse effects of study medications were assessed during the trial. Results. Although improvement in the severity of DD was observed in both treatment groups (P < 0.001), patients receiving Calendula ointment had significantly fewer rash sites compared to Aloe group (P = 0.001). No adverse effect was reported from either of the medications. Discussion. The evidence from this study suggests that topical Aloe and in particular Calendula could serve as safe and effective treatment for the treatment of diaper dermatitis in infants.
During the past few years, there have been several studies for portfolio management. One of the primary concerns on any stock market is to detect the risk associated with various assets. One of the recognized methods in order to measure, to forecast, and to manage the existing risk is associated with Value at Risk (VaR), which draws much attention by financial institutions in recent years. VaR is a method for recognizing and evaluating of risk, which uses the standard statistical techniques and the method has been used in other fields, increasingly. The present study has measured the value at risk of 26 companies from chemical industry in Tehran Stock Exchange over the period 2009-2011 using the simulation technique of Monte Carlo with 95% confidence level. The used variability in the present study has been the daily return resulted from the stock daily price change. Moreover, the weight of optimal investment has been determined using a hybrid model called Markowitz and Winker model in each determined stocks. The results showed that the maximum loss would not exceed from 1259432 Rials at 95% confidence level in future day.
Background: Renal cell cancer (RCC) is the tenth most common malignancy in adults. In recent years, several approaches of active and passive immunotherapy have been studied extensively in clinical trials of patients with RCC. The aim of this systematic review was to assess the clinical efficacy of various approaches of specific immunotherapy in patients with RCC. Methods: We searched Medline, Scopus, CENTRAL, TRIP, DART, OpenGrey and ProQuest without any language filter through to 9 October 2015. One author reviewed search results for irrelevant and duplicate studies and two other authors independently extracted data from the studies. We collated study findings and calculated a weighted treatment effect across studies using Review Manager (version 5.3. Copenhagen: The Nordic Cochrane Centre, the Cochrane Collaboration). Results: We identified 14 controlled studies with 4013 RCC patients after excluding irrelevant and duplicate studies from 11,319 references retrieved from a literature search. Overall, five autologous tumor cell vaccines, one peptide-based vaccine, one virus-based vaccine and one dendritic cell (DC)-based vaccine were studied in nine controlled studies of active specific immunotherapies. A total of three passive immunotherapies including autologous cytokineinduced killer (CIK) cells, auto lymphocyte therapy (ALT) and autologous lymphokine-activated killer (LAK) cells were studied in four controlled studies. The clinical efficacy of tumor lysatepulsed DCs, with CIK cells was studied in one controlled trial concurrently. The overall quality of studies was fair. Meta-analysis of seven studies showed that patients undergoing specific immunotherapy had significantly higher overall survival (OS) than those in the control group [hazard ratio (HR) = 0.72; 95% confidence interval (CI) = 0.58-0.89, p = 0.003]. In addition, a meta-analysis of four studies showed that there was a significant difference in progressionfree survival (PFS) between patients undergoing specific immunotherapy and patients in control groups (HR = 0.86; 95% CI = 0.73-1, p = 0.05). Conclusions: Results of this systematic review suggest that some specific immunotherapies such as Reniale, ACHN-IL-2, Newcastle disease virus (NDV) virus-infected autologous tumor cells, ALT and CIK treatment could be beneficiary for the treatment of patients with RCC.
Background and objective: Prostate cancer is one of the most widespread cancers among men throughout the world. In addition, it is the second cause of death after lung cancer. Occurrence of the prostate cancer is variable in various regions of the world. Solely, there are three known risk factors for the prostate cancer, including: Age, inheritance and ethnic origin. ELAC2 protein is a phosphodiesterase enzyme encoded by ELAC2 gene in human. This gene is placed on chromosome 17, and it is believed that product of the mentioned gene is an endonuclease contributed in puberty of mitochondrion’s tRNA. From clinical viewpoint, variables of ELAC2 gene such as Ser217Leu and Ala541Thr Missense mutations which are accompanied by hereditary prostate cancer ( HPC2 ).Objective of this study is to investigate Ser217Leu (rs4792311) and Ala541Thr (rs5030739) polymorphisms in the individuals with prostate cancer or those who are suspicious of prostate cancer with family past record/history. Study method: In this study conducted by case-control method in 2018, 102 men with prostate cancer and 98 men being suspicious of prostate cancer out of 10 families referred to shahid Rajaei Hospital in Tonekabon county to study and check were investigated. After collection of data using questionnaire, sampling from individuals and performance of the rest steps, study of polymorphism was carried out by PCR sequencing technique, and the results were analyzed by Chromas software. Finding: Of the total studied 102 individuals, 44 individuals (43.1%) were homozygote for Ser217Leu mutation, 36 individuals (35.2%) were heterozygote and 22 individuals (21.5%) lacked Missense mutation. for Ala541Thr mutation, 18 ones (17.6%) were heterozygote and 84 ones (82.3%) lacked Missense mutation. For Ser217Leu mutation, out of 98 suspicious individuals, 21 individuals (21.4%) were homozygote. 6 individuals (6.1%) were heterozygote and 71 individuals (72.4%) lacked the mutation. For Ala541Thr mutation, 15 ones (15.3%) were homozygote and 84 ones (84.6%) lacked the studied mutation. Conclusion: Results of this research showed that, in the individuals with the prostate cancer, there is a relationship between Ser217Leu and Ala541Thr polymorphism of ELAC2 gene and/with prostate cancer, and the suspicious individuals gotten involved in the mutation must take action to prevent this cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
