A study of the etiology of referred Otalgia

Introduction: Otalgia is one of the complaints which may occur at any age. The etiology of the pain may be in the ear, structures around the ear or other head and neck structures. This is caused by the complex nervous connections in the head and neck areas, the ear, the pharynx and the nose. Since understanding the etiologies of referred otalgia can help in the assessment and treatment of the disease, this research was conducted to identify the etiologies of referred otalgia in patients visiting the ENT Clinic in Gorgan, Iran. Materials and Methods: This prospective research was conducted on patients who visited the ENT Clinic with an earache, but in initial assessments the ear was normal. Patients' data consisting of sex, age, complaint, the inflicted side, physical findings in the ear, the nose, the throat and head and neck were recorded in a questionnaire. These data were then analyzed with SPSS software. Results: Of 770 patients with otalgia, 94 patients (12.2%) had referred otalgia. Of these patients 27.7% were men and 72.3% were women. The most common etiology of referred otalgia was dental problems (62.8%), and one patient who was being treated for pharyngitis had carcinoma of the base of the tongue. In 47.8% of cases the pain was in the left ear, in 43.4% in the right ear, and in 8.7% it was bilateral. Conclusion: In view of the fact that a significant proportion of the patients who complained of otalgia had no pathologies in the ear, thorough physical examination in adjacent structures especially teeth should be performed and malignancies should be considered as a possible etiology of otalgia

Deficiencies of the microelements, folate and vitamin B12 in women of the child bearing ages in Gorgan, Northern Iran

Background: The deficiencies of folic acid, vitamin B12, and microelements during pregnancy may affect the health of newborns. Objectives: To assess the serum levels of folate, vitamin B12, iron, zinc and copper in healthy women of the childbearing ages in Gorgan, northern Iran. Methodology: This descriptive, cross-sectional study was carried out on 100 women of childbearing ages in northern Iran during November 2007-March 2008. The serum levels of folate, vitamin B12, iron, copper and zinc were evaluated by laboratory tests. Results: Iron, copper, folate, vitamin B12 deficiencies and folate with vitamin B12 deficiency were detected in 13%, 32%, 13%, 32% and 11% women of the childbearing ages, respectively. According to the ethnicity, vitamin B12, folate and iron deficiencies in the Sistani group were observed in 38.3%, 12.9% and 12.9% of the women, respectively. In the native Fars group, the above mentioned deficiencies were found in 31.1%, 13.4% and 7.5% of the subjects. Folate and vitamin B12 deficiencies were observed in the urban habitant in 32.7% and 11.5% of the subjects as compared to those in the rural habitant (in 30.4% and 15.2%of the subjects respectively). The folate deficiencies in the under and above 18 years old subjects were 22.2% and 9.9%, respectively. Conclusions: This study showed that the deficiency of the micronutrients was considerable in women of the childbearing ages in Gorgan, northern Iran

Comparative efficacy of deferiprone, deferoxamine and combination of deferiprone and deferoxamine on serum ferritin value in Beta-Thalassemia patients

Background: Iron overload is a predictable and life-threatening complication in patients with thalassemia. Effective and convenient iron chelation remains one of the main targets of clinical management of thalassemia major. The development of a safe and effective chelator has been the goal for many years. Aims and Objective: It was aimed to compare the effect of deferiprone, deferoxamine and combination of deferiprone and deferoxamine on serum ferritin value in beta-thalassemia patients. Material and Methods: This controlled clinical trial was conducted on 46 major beta-thalassemic patients. Fifteen patients in deferiprone group received deferiprone 75mg/kg/day three times a day orally. Nineteen patients in deferoxamine group received deferoxamine 30-50 mg/kg/day subcutaneously for 8-12 hours/day and 5 days per week. Twelve patients in combined therapy group received deferiprone 75 mg/kg/day three times a day orally with deferoxamine 30–50 mg/kg subcutaneously every other day. Serum ferritin value was measured at the beginning and at the end of 6th and 12th months of study. Results: The mean of serum ferritin value in deferiprone group insignificantly increased from 2731± 1398.5 μg/L at the beginning to 2788.5 ± 978.6 μg/L and to 3331.8 ± 1833.9 μg/L at the end of 6th and 12th months of study, respectively. The mean of serum ferritin value in deferoxamine group insignificantly increased from 2883.5 ± 1598.1 μg/L at the beginning to 2935.3 ± 1258.2 μg/L at the end of 6th month of study and decreased to 2773.8 ± 1216.1 μg/L and 12th month of study. The mean of serum ferritin level in combined therapy group significantly decreased from 7498.7 ± 3512.9 μg/L at the beginning to 4839.9 ± 2698.2 μg/L (P < 0.001) and to 4298.2 ± 2288.7 μg/L (P < 0.001) at the end of 6th and 12th months of study, respectively. Conclusion: Combined therapy significantly decreases serum ferritin level. Study suggests deferiprone as a significant addition to support therapy in patients with betathalassemia major on regular transfusion regimens. © 2015 Journal of Krishna Institute of Medical Sciences University

Modeling of influential predictors of gastric cancer incidence rates in Golestan Province, North Iran

Golestan province has a reputation for relatively high incidence rates of gastric cancer in Iran. Along with dietary, lifestyle and environmental influential factors, soil selenium and high levels of pesticide used may exert influence in this region. The present study was designed for modeling the influential predictors on incidence of gastric cancer in Golestan. All registered cases of gastric cancer from March 2009 to March 2010 (49 females and 107 males) were investigated. Data were gathered by both check list and researcher made questionnaire (demographic, clinical and lifestyle characteristics) and analysed using logistic regression. Mean (±SD) age at diagnosis was 62.9±13.8 years. CIR and ASR of gastric cancer showed 9.16 and 13.9 per 100,000 people, respectively. Based on univariate logistic regression, a history of smoking (OR= 2.076), unwashed hands after defecation (OR= 2.612), history of cancer in relatives (OR= 2.473), history of gastric cancer in first-degree relatives (OR= 2.278), numbers of gastric cancers in first-degree relatives (OR= 2.078), history of X-ray and dye exposure (OR= 2.395), history of CT scan encounter (OR= 2.915), improper food habits (OR= 3.320), specific eating behavior (OR= 0.740), consumption of probable high risk foods (OR= 2.942), charred flesh (OR= 1.945), and animal fat (OR= 2.716) were confirmed as a risk factors. Changes in lifestyle may be expected to increase gastric cancer incidence dramatically in the near future. Therefore, appropriate educational interventions should be designed and implemented by competent authorities

Morphometric evidences for regional variation in potential of neural plasticity

The neural plasticity showing the ability of nervous system to change its structure and function is a well-documented fact. However regional variation within a CNS structure to undergo plastic changes has been shown by limited studies. Along medial-lateral sequences of parasagittal sections, the molecular layer thickness of primary fissure borderlands in rat cerebellar left hemisphere was studied to assess the regional difference in plasticibility. Despite the homogeneity of cerebellar histology, this study showed that there is a significant interlobular difference between ML thicknesses of Prf borderlands. In addition, it revealed that the thickness alters in a significant trend within each borderland. The quantitative heterogeneity of cerebellar architecture such as variation of cortical thickness may provide some evidences to show that different regions of a homogenous cortex, even two adjacent borderlands and areas within them, can have different potentials for plasticity. © 2006 Sociedad Chilena de Anatomía

Tendency to Hookah among Adolescents in Kurdkoy City

Background and Objective: Nowadays, smoking is a widespread health problem in the world. Hookah smoking is common in many countries, especially in the Middle East and Africa. This study aimed to investigate the causes of hookah smoking in adolescents in Kurdkoy, 2013. Material and Methods: This cross-sectional study was conducted on 266 teenagers selected via multi stage sampling. The questionnaires were distributed among the people who were present at the Coffeehouses and the results were reported by descriptive statistics. Results: The results showed that 51.5% of the participants said they use Hookah every day. The reasons were pastime (56.4), unemployment (41.7), Pleasant feeling (33.8), being with friends (33.5), fatigue reduction (33.5) and the availability of hookah (32.3). Conclusion: To minimize the tendency to Hookah smoking, we recommend planning some activities for leisure time, "learning to say no" and training how to reduce anxiety and fatigue

Is opioid dependency related to coping strategies?

Using opioid for recreational purposes has a very long history in Iran. Social influence is a useful framework in understanding how the social environment affects the individual's behavioral choices to use drugs. We compared opioid dependents (n=149) with controls (n=221) on measures of coping strategies using the Jalowiec Coping Scale and some socioeconomic factors. The differences in 10 of 15 coping strategies were significant in the study groups (P<0.05). Although, the combined score of problem-oriented and affective-oriented items did not show any significant difference between the two groups. There was a significant relation between opioid dependence with smoking cigarettes (P<0.001), lower education (P=0.002), being employed (P<0.001), having children (P<0.001), and being married (P<0.001). Educational programs to improve problem solving and coping skills can be helpful to reduce the rate of dependency to opioid and smoking cigarettes. © 2015, Sadeghali Taziki, et al

Heart surgery waiting time: Assessing the effectiveness of an action

Background: Waiting time is an index assessing patient satisfaction, managerial effectiveness and horizontal equity in providing health care. Although heart surgery centers establishment is attractive for politicians. They are always faced with the question of to what extent they solve patient’s problems. Objectives: The objective of this study was to evaluate factors influencing waiting time in patients of heart surgery centers, and to make recommendations for health-care policy-makers for reducing waiting time and increasing the quality of services from this perspective. Patients and Methods: This cross-sectional study was performed in 2013. After searching articles on PubMed, Elsevier, Google Scholar, Ovid, Magiran, IranMedex, and SID, a list of several criteria, which relate to waiting time, was provided. Afterwards, the data on waiting time were collected by a researcher-structured checklist from 156 hospitalized patients. The data were analyzed by SPSS 16. The Kolmogorov Smirnov and Shapiro tests were used for determination of normality. Due to the non-normal distribution, non-parametric tests, such as Kruskal-Wallis and Mann-Whitney were chosen for reporting significance. Parametric tests also used reporting medians. Results: Among the studied variables, just economic status had a significant relation with waiting time (P = 0.37). Fifty percent of participants had diabetes, whereas this estimate was 43.58% for high blood pressure. As the cause of delay, 28.2% of patients reported financial problems, 18.6% personal problem and 13.5% a delay in providing equipment by the hospital. Conclusions: It seems the studied hospital should review its waiting time arrangements and detach them, as far as possible, from subjective and personal (specialists) decisions. On the other hand, ministries of health and insurance companies should consider more financial support. It is also recommend that hospitals should arrange preoperational psychiatric consultation for increasing patients’ emotionally readiness. © 2015, Iranian Red Crescent Medical Journal

Birth prevalence of oral clefting in northern Iran

Objective: To explore the prevalence of oral clefting in northern Iran. Setting: In the Dezyani hospital 37,951 live births from 1998 through 2003 were screened for oral clefts. Clinical and demographic factors of diagnosed cases, including birth date, ethnicity, type of oral cleft, parental consanguinity, and coexisting anomalies, were recorded for analysis. Results: The overall prevalence of oral clefting was 0.97 per 1000 live births. The prevalence of cleft lip with or without cleft palate and isolated cleft palate was 0.60 and 0.37 per 1000, respectively. The prevalence of oral clefting was 1.08 per 1000 male births and 0.86 per 1000 female births. With respect to parental ethnicity, the prevalence of oral clefting was 0.86, 0.88, and 1.47 per 1000 in Fars, Turkman, and Sistani, respectively. Conclusions: The prevalence of oral cleft among live births in the Dezyani hospital is similar to that reported in the previous studies for Iran and whites

Immunogenicity evaluation of a DNA vaccine expressing the hepatitis C virus non-structural protein 2 gene in C57BL/6 Mice

Backgrounds: Most of the hepatitis C virus (HCV) infections elicit poor immune responses and 75% to 85% of cases become chronic; therefore, the development of an effective vaccine against HCV is of paramount importance. In this study, we aimed to evaluate co-administration of HCV non-Structural Protein 2 and IL-12 DNA vaccines in C57BL/6 mice. Methods: A plasmid encoding full-length HCV NS2 protein (non-structural protein 2) was generated and used to vaccinate mice. Negative control (an empty expression vector) was also employed to evaluate the background response. To investigate immune responses against vaccine, C57BL/6 mice received three doses of the vaccine with a two-week interval. Cellular immunity was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay for lymphocyte proliferation, lactate dehydrogenase release for cytotoxic T lymphocyte (CTL) activity and cytokine assay. Results: The findings demonstrated that immunization of mice with plasmid expressing HCV NS2 induced CTL response, interferon gamma production, and lymphocyte proliferation compared to negative control. The results also demonstrated that co-administration of IL-12 with the HCV NS2 plasmid induced significantly better immune response in C57BL/6 mice. Conclusion: DNA vaccine encoding HCV NS2 is an effective candidate that can trigger CTL-based immune response against HCV. In addition, the results suggested that combining the DNA vaccine approach with immune stimulatory cytokines may significantly enhance antigen-specific immune responses
