Page 2IntroductionHemimandibular hyperplasia is a facial deformity which may develop in any age and includes a unilateral enlarged mandibular condylar head, deviation of mandible and chins, elongated condylar neck or ramus, and an occlusal cant with open bite. Different surgical treatments are proposed in the literature from simple low or high condylectomy to more complex procedures combining osteotomies in different sites of the mandible. Surgical procedure is defined by the clinical evaluation and scintigraphic diagnosis of activity or inactivity in the center of condylar growth..Case PresentationThis case report describes a 30-year-old female patient with left hemimandibular hyperplasia with activity of condylar growth, that was successfully treated with low condylectomy, asymmetric lefort I osteotomy and inferior border ostectomy on the affected side, and associated with a unilateral sagittal split ramus osteotomy on the contra-lateral side..DiscussionThe innovation on nerve dissection by removing the overlying buccal bone and performing inferior ostectomy under direct visualization of the nerve, proved to be a safe technique with a low risk of nerve damage..Keywords: Hyperplasia, Surgery, Face

Page 3BackgroundIn the recent years, the focus of consumers to less popular fruits such as Cornus mas, with unusual flavor as well as rich antioxidant and anthocyanins content has increased. C. mas fruits have been used for treatment of gastrointestinal disorders..ObjectivesThe aim of this study was to investigate the hepatoprotective effect of C. mas fruits extract (CMFE) against carbon tetrachloride-induced hepatic damage in male albino rats..Materials And MethodsHepatotoxicity was induced by administration of CCl4 (1 mL/kg i.p. (Intraperitoneal)) in olive oil with 1:1 dilution ratio. To evaluate the effect of CMFE on the disease progression, serum marker enzymes, serum total protein and albumin, liver lipid peroxidation and antioxidant enzymes activities were determined in CCl4-induced hepatotoxicity..ResultsOral administration of CMFE to rats for 16 days, afforded significant (P < 0.05) hepatoprotection against CCl4-induced elevation in serum marker enzymes activities, serum total protein and albumin, and liver lipid peroxidation, as well as significant (P < 0.05) reduction in liver antioxidant enzymes activities, such as superoxide dismutase, catalase and glutathione peroxidase activities..ConclusionsThe present study indicated that the beneficial effect of C. mas extract might be due to the presence of some antioxidant components with membrane-stabilizing effects..Keywords: Carbon Tetrachloride, Free Radicals, Lipid Peroxidation

Page 4BackgroundAppropriate management of chronic conditions requires full knowledge of the situation-related complications and preventive behaviors, which can improve or eliminate these complications. It is also essential to evaluate treatment methods regularly, with respect to the features of each social group and the available resources..ObjectivesThis study aimed to evaluate the level of knowledge, attitudes and practices of adolescents with severe hemophilia, with regard to the prevention of related complications..Patients andMethodsA pilot study was conducted in a hemophilia center (East Azerbaijan, Iran). In total, 40 adolescents with severe hemophilia were included in the study. The Nazzaro et al. questionnaire was conducted using a telephone interview. Data were analyzed using SPSS (version 13). Results were expressed as frequencies, means and standard deviations..ResultsA relatively large proportion of the subjects (46% and 64%) had not been informed of the transmission methods of hepatitis B and C, respectively. Bleeding episodes (61%) and joint disorders (26%) were the main concerns for the majority of subjects. Less than half (38%) of the respondents had had an experience of managing a bleeding episode within a one hour period. Half of the subjects were involved in vigorous activity, which ranged from one to more than five days per week, and only 37% of the subjects participated in moderate physical activity for more than 5 days per week..ConclusionsThe current study highlights the need to improve the level of knowledge, attitudes and practices of adolescents with severe hemophilia. The prevention of complications, can be assisted by providing; education, skill sessions and group discussions..Keywords: Complications, Prevention, Control, Knowledge, Attitude, Adolescents

Page 5BackgroundPolycyclic Aromatic Hydrocarbons (PAHs) are the most important environmental contaminants all over the world where wide studies have been conducted on their hazards on environment and living organisms; especially human..ObjectivesThe aim of this study was to investigate the quantitative uptake of Phenanthrene’s (as one of the most important PAHs in crude oil) by Salicorniaeuropea and also the effectiveness of crude oil content on normal condition of this plant especially at various concentrations..Matherials andMethodsSalicornia plantlets were taken from Eshtehard plant bank which is located in Alborz, Iran. They were transplanted and exposed to various t concentrations of crude oil (4.5-16-27.5-32-36.5 g/kg soil). Spectrophotometery and Gas Chromatography-Mass Spectroscopy methods were used to determine and identify the phenanthrene uptake in roots and stalks, also the plants’ appearance were checked out..ResultsThe highest uptake was at eight mg crude oil, per one g of soil and the least uptake was at 13.75 mg crude oil, per one g of soil. It seems that physical characteristics of crude oil are the main reasons of damages to plant tissue..ConclusionsConcerning the ability of Salicorniaeuropea to survive in the contaminated areas, it might be suitable that endemic types of this plant would be cultivated in contaminated coast lines..Keywords: Petroleum, Polycyclic Hydrocarbons, Aromatic, Biodegradation, Environmental Hazard

Page 6BackgroundDiabetes mellitus and its complications are the leading causes of mortality and morbidity in human..ObjectivesThe aim of this study was to determine the prevalence of diabetes mellitus and prediabetes among adults older than 20 years in Ilam province..Materials And MethodsThis cross sectional–descriptive study was carried out on 3915 subjects aged older than 20 years. The sampling was done by census. Fasting blood glucose and two hours post prandial glucose level after administration of 75 g oral glucose were measured. American Dietic Association criteria were used for diagnosis of diabetes mellitus and prediabetes..ResultsThe prevalence of diabetes was 7.04% (4.52% women, 2.52% men) and the prevalence of prediabetes was 8.58% (5.59% women, 2.98% men). Thehighest prevalence of diabetes and prediabetes were observed on sixth and fifth decades, respectively Approximately two percent % of population, mostly men, were unaware of their pre-existing diabetes..ConclusionsBecause of increasing prevalence of prediabetes at earlier age, it seems necessary to reconsider the screening age in urban areas and perform the screening in all adults at younger ages..Keywords: Prevalence, Insulin Resistance, Screening, Lifestyle

Page 8BackgroundHumor is a valuable tool for establishing a conducive environment in classroom learning. From the teachers’ point of view, “how” to teach effectively is a challenging task. It demands creativity and imagination to capture students’ attention and interest in one’s teaching. From students’ point of view, a monotonous lecture would hinder their interest to concentrate in the classroom..ObjectivesThe present study had two objectives; firstly to explore students’ perspectives on the use of humor in classroom teaching and secondly to explore students’ perspectives regarding teachers, using humor in classroom teaching..Materials And MethodsStudents were requested to respond to two questionnaires focusing on items related to the use of humor in classroom teaching, on a 4-point Likert scale (4 = Strongly agree; 3 = Agree; 2 = Disagree; 1 = Strongly disagree). Data were summarized using median grade with interquartile range (IQR). Frequency analysis of the responses was performed and agreement to each item was calculated by adding the frequencies of strongly agree and agree responses. Disagreement to each item was calculated by adding the frequencies of strongly disagree and disagree responses..ResultsStudents (n = 157; 97.5%) opined that humor if incorporated appropriately in classroom teaching is a good thing and also helps in better retention of the topic being taught (n = 141; 75.15%). Majority of students (n = 158; 98.12%) responded that use of humor in classroom teaching facilitates a good teacher-student relationship. Majority of students (n = 146; 90.67%) also felt that having a good sense of humor is an attribute of an effective teacher..ConclusionsThe present study revealed that students prefer humor to be integrated into classroom teaching. The thoughtful use of humor fosters better teacher-student relationship which might culminate in better student learning..Keywords: Humor, Teaching, Education, Medical, Undergraduate
