Conservative Management of Periapical Cementoblastoma: A Case Report

As a rare ectomesenchymal neoplasm, benign cementoblastoma comprises less than 6% of all odontogenic tumors. The typical treatment plan involves surgical excision and extraction of the affected tooth. Limited evidence, however, suggests the conservative management of this condition as the best treatment. This article discusses the case of a 32-year-old man who had benign cementoblastoma and underwent conservative treatment. The diagnosis was established based on clinical and radiological features analyses. Root canal therapy was performed on the tooth, followed by enucleation, curettage, apicoectomy, and guided bone regeneration (GBR) 30 days later. After a year of follow-up, there was no recurrence, and the tooth was in healthy conditions. These findings demonstrated that the tooth affected by cementoblastoma can be saved. It was treated conservatively to preserve the patient’s oral health and masticatory function

Musculoskeletal disorders in hemodialysis patients: prevalence, clinical symptoms, and associated factors

Introduction: One of the major public health problems is end-stage renal disease (ESRD). ESRD is commonly associated with musculoskeletal disorders (MSDs). Objectives: Due to the importance of MSDs in hemodialysis patients and the absence of sufficient studies in Iran, this study aims to investigate MSDs in hemodialysis patients. Patients and Methods: This cross-sectional study was conducted on 75 patients with ESRD, who were under hemodialysis at the special diseases center of Birjand university of medical sciences, south Khorasan, Iran. Inclusion criteria were history of at least 2 years of hemodialysis, and age more than 18 years. All patients with previous neurological disorders, previous rheumatic diseases, previous arthroplasty of the limbs, and severe psychological disorders were excluded from the study. Baseline characteristics and laboratory data collected. MSDs examined based on the Nordic Musculoskeletal Screening Questionnaire (NMQ). Data were described using central tendency, CHI-SQUARE test, and Fisher’s exact test were used. The significance level in this study was P0.05). Dialysis etiology, knee osteoarthritis, shins pain, knee pain and knee range of motion had significantly difference between groups (respectively, P=0.047, P=0.003, P=0.012, P=0.001, P=0.002). Conclusion: The frequency of MSDs in these patients was 84.0%. There was a significant association between MSDs with the cause of hemodialysis, lower limb pain, and knee osteoarthritis

Arsenic, Cadmium, Chromium, and Lead in Children’s Products in Iran

Background: Non-standard creativity tools and entertainment products may contain heavy metals. Children are more sensitive than adults to this potentially toxic chemicals. This study aimed at investigating harmful elements in children’s products in Iran. Methods: In this descriptive-analytical study, Iranian samples (13 play dough samples, 6 finger paint, and 1 face paint sample) and 10 imported samples were investigated by atomic absorption spectrophotometry. The statistical analyses were performed using the SPSS statistical package (version 19). Results: The results of this study showed that the lead content of 2 samples of play dough (76%), 10 samples of finger paint (100%) and 3 samples of face paint (100%) was higher than the permissible limits set by the Iranian National Standards Organization. Lead and cadmium contents of 100% of the samples of play dough, along with the face and finger paints exceeded the permissible limits set by the European Union. Conclusion: Research on prolonged exposure to harmful elements and comprehensive risk characterization for toys is recommended

Designing an Adaptive Nuero-Fuzzy Inference System for Evaluating the Business Intelligence System Implementation in Software Industry

The main goal of research is designing an adaptive nuero-fuzzy inference system for evaluating the implementation of business intelligence systems in software industry. Iranian software development organizations have been facing a lot of problems in case of implementing business intelligence systems. This system would be helpful in recognizing the conditions and prerequisites of success or failure. Organizations can recalculate the neuro-fuzzy system outputs with some considerations on various inputs to figure out which inputs have the most effect on the implementation outputs. By resolving the problems on inputs, organizations can achieve a better level of implementation success. The designed system has been trained by a data set and afterwards, it has been evaluated. The trained system has reached the error value of 0.08. Eventually, some recommendations have been provided for software development firms on the areas that might need more considerations and improvements

Perceived social support among students of medical sciences

Background: Social support is emotional and instrumental assistance from family, friends or neighbors, and has an important but different impact on individuals, mainly depending on contextual factors. Objective: To determine the status of perceived social support and related personal and family characteristics of medical sciences students in Ahvaz, Iran. Methods: In this cross-sectional study, the target population included the students of Ahvaz Jundishapur University of Medical Sciences in the second semester of 2013-2014, of whom 763 were selected by cluster random sampling method. The study tool was a two-part questionnaire containing 48 self-administered questions including 25 questions of measurements of personal and family characteristics and a Persian modified version of Vaux's social support scale (Cronbach's α=0.745). Data were analyzed with T test, ANOVA and chi-square and using SPSS version 16 and 0.05 was considered as the level of significance. Results: The mean score of the perceived social support was 17.06±3.6 and 60.3% of them reported low social support. There was a significant relationship among the perceived social support and sex (p=0.02), faculty (p<0.0001), ethnicity (p=0.034) and the duration of weekly residence in dormitory (p=0.031). But no significant relationship was found between this variable and other individual and familial characteristics. Conclusion: Based on students` low social support and importance of social support in reducing stress and academic failure, the planners need to provide efficient supportive interventions for student

Striving for Being in the Line of Life: Personal Active Ageing Strategies in Iranian Seniors

Active ageing is a multidimensional, relative, and context-dependent concept with different paths and outcomes. This qualitative study aimed to explore personal active aging strategies in a specific context. Following a directed thematic analysis procedure, we conducted semi-structured individual interviews with 39 seniors (men and women) between the ages of 60-97 years selected with purposeful sampling, data collection and analysis were concurrent. We used directed content analysis to analyze the data from interviews, written narratives, and field notes. The reliability of data was fulfilled following Lincoln and Guba criteria. We stopped data collection when no new concepts were added, and data saturation occurred. Based on the experience of seniors, we identified four categories: (a) Reventive, (b) Coping, (c) Internal Self-Control, and (d) Opportunity Exploiting Strategies. These described the active aging strategies when encountering age-related change. Utilizing these strategies, the senior accompanied the lifetime. The finding suggests that active aging is a continuous process in confronting age-related change. The identified strategies can help promote active aging by familiarizing the elderly with opportunities of life and training them in how to use these strategies
