In the present survey all together 670 students were chosen randomly. The rate of goiter prevalence was 46.3% and 55.7% among the students of Ilam and Arkavas, respectively. Goiter prevalence rate among females was higher than in males. Prevalence of giother was significantly different between the two cities, also between females and males in Arkavas and females in two cities (P<0.05). In comparison the females had better physical growth than males. Although there was no significant difference between weight and height as well as socio-economic state in comparison with thyroid size, but physical growth and socioeconomic indicators in Arkavas were lower than in Ilam. There was no significant relationship between the size of thyroid and urinary excretion of iodine. The amount of iodine in drinking water was 3.2 and 0.65 Mic.gr/Lit, respectively. Low level iodine drinking water and protein-energy malnutrition are important factors for prevalence of goiter in two cities. According to our results although the value of urinary iodine is normal but prevalence of goiter rate related to the iodine deficiency is due to the past deficiency.

Background, Materials and Methods: In order to evaluation the newborn’s nutrintional status in Bojnoard, 566 healty, Single full term newborn were examined. In this examination, the indicators of weight for age, height for age, weight for height and head circumference for age in the beginning of birth were calculated and compared to National Center of Health Statistics Standards (NCHS), with making use of fifth percentile of reference society for malnutrition edge, was specified that, nutritional status in above newborn’s is better than reference society’s newborns. Results&Conclusion: The data analysis of this research showed that between mother’s near delivery weight (P = 0.037) and mother’s nutritional attitude (P= 0.004) and numbers of family( P = 0.006 ) with height for age, between newborn’s sex (P= 0.004), mother’s age(P= 0.038), mother’s near delivery weight(P = 0.042) and mother’s nutritional practice during pregnancy (P= 0.041) with weight for height and between mother’s age (P= 0.043), mother’s near delivery weight (P= 0.048), mother’s height (P= 0.025), mother’s nutritional knowledge (P = 0.046) with head circumference for age, there is significant statistic connection. Also there was a weak statistic connection between newborn’s nutritional status and grade of birth (P= 0.09), but there is no significant meaningful connection between wanted or unwanted newborn and mother’s nutritional knowledge.

Background: Adolescence (10-19 years) is one of the most challenging periods in human development. A second period of rapid growth occurs during the teen years. Not much information is available on the effect of the socio-economic status on the outcome of nutrition education in teenage girls. Objective : The purpose of this study was to determine the effect of socio- economic status on the efficacy of nutrition education in promoting the nutritional knowledge, attitude and practice in first-grade guidance school girls in Tehran.

Material & Methods: A total of 300 students were selected from 11 guidance schools by simple sampling and divided into three groups: 1- guide-book, 2- group discussion, 3- control. The knowledge and attitude data were collected using pre-test and post-test questionnaires and the personal-socioeconomic data were collected using general questionnaires. The students in group 1 were given the guide-book and required to study it at home, while group 2 students were told to discuss among themselves the contents of the guide-book. The control group was given nothing to study or to do.

Results: Nutrition education did not have a significant effect on the increase in the attitude score in the students whose grade-point average and their mother’s education level were high. (p= 0.13, p=0.29). Only mother’s education level independently from the type of education was associated with the difference of knowledge score means (p =0.07).There was interaction between nutritional education and monthly pocket- money with regard to the increase in the knowledge score (p =0.03).

Conclusion: Overall, exception of monthly pocket money, the effect of education on the nutritional knowledge and attitude was independent from other variables. Only mother’s education associate with the difference of knowledge score means.

Background: We aimed to demonstrate the mechanism of fracture and functional outcome of patients with hip injury in our clinical setting.
Methods: In a historical cohort, all women 50 years of age and older admitted to three university hospitals of Tehran University of Medical Sciences (Shariati, Imam Khomeini and Sina) with the diagnosis of hip fracture from 21 March 2003 to 21 March 2004 were included in this study (n=115). Follow up was conducted via telephone post and even home visit to record the functional status of the patients at the time of study (5 Jan 2005) measured with Barthel index in addition to the exact mechanism of injuries.
Results: The mean and standard deviation of age were 76.3 ± 10.6 years. About 88.7% of injuries had occurred at home (65.2% on the carpet), the remaining happening in the streets. Mean length of hospitalization was 11 ± 7.9 days. Among our patients, 71% could mobilize spontaneously without aids before injuries. This had reduced to 20% at the time of follow-up. The mean Barthel index was 97.2 ± 8.2 before fracture and 75 ± 21.1 at the present. Among our patients, five cases died during hospitalization and 29 of them died afterwards (total: 34 or 29.6%).
Conclusion: The most common external cause of injuries in our cases was stumbling at home especially on carpeted surfaces. This necessitates preventive measures aimed at physical standards of houses and education of elderly on healthy locomotion, indoors.

Background: The effects of population aging are becoming apparent throughout the world. Diseases, such as cardio-vascular disease (CVD) and diabetes, are among the most important factors affecting morbidity and mortality, especially in the elderly. These diseases not only result in huge economic costs for treatment and care, but also results in hardship and time lost for relatives of the afflicted individuals. The association between nutritional status and disease is well known. In the present study, the effects of both under-nutrition and over-nutrition on the prevalence of disease are monitored in an urban Iranian elderly population. Thus far, no similar study has been performed in the Iran.
Methods: This cross-sectional study was conducted in Isfahan, Iran, during late 2003 on 1694 elderly people (731 males, 963 females), aged 60 years and older. Subjects were randomly chosen from all urban elderly people during a door-to-door and weight and height survey. They were selected using a cluster sampling method, each containing 30 clusters. From each cluster, 58 elderly were selected at random. Using each subjects body mass index (BMI), the nutritional status was categorized as overweight (BMI greater than 25), underweight (BMI less than 19) and normal (having a BMI equal to or more than 19 and equal to or less than 25). Any illnesses known to each subject were also recorded.
Results: Results showed that 4.7% of the subjects were underweight and 61.2% overweight. Women were more likely to be overweight and long periods of watching television increased the risk of overweight in all subjects. Being overweight was associated with diabetes and coronary vascular diseases, and lean people were less likely to suffer from such diseases.
Conclusion: This study indicates a high prevalence of overweight among the Iranian elderly population, indicating the need for improvement in nutritional status in order to reduce the prevalence of diabetes and CVD.

Background: Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system resulting from demyelination and axonal loss. Although treatment of MS has progressed, patients continue to have attacks and treatment for such episodes remains a subject of ongoing study. The object of this study is to determine the effect of intravenous methylprednisolone (IVMP) on the degree of disability in MS patients.
Methods: This cross-sectional study involved 63 patients with a definite diagnosis of MS, based on the MacDonald criteria, at the Iranian Center for Neurological Research at Imam Khomeini Hospital, Tehran, Iran, from March 2004 through March 2005. After obtaining informed consent, investigators gathered data including each patient's age, gender, pyramidal activity status, cortical, cerebellar and brain stem activity status, sensory signals in the extremities, including vibration, touch, pain, position, visual status, as well as bladder and intestinal activity, and Expanded Disability Status Scale (EDSS) score. SPSS version 11 was used for data analysis.
Results: A five-day regimen of IVMP (5g) significantly reduced the immediate post-treatment score from 4.595 to 3.635, which represents a 96% improvement in the EDSS. The greatest change in functional system disability was seen in the pyramidal system with a mean score of 1.13. After treatment, the rate of disability reduction in the sensory system, cerebellum, vision, bladder and intestinal activity was 0.57, 0.49, 0.46, 0.4, and 0.38, respectively. Patients who had experienced fewer relapses responded better to treatment. There was no statistically significant relationship between patient age and the level of response to treatment. However, the rate of disability reduction after treatment was greater in males than females (p=0.05).
Conclusion: These results show that IVMP treatment induces an immediate post-treatment effect that could partly account for clinical and radiological improvement in MS patients. However, further study is required to determine the possible long-term, or even intermediate-term, effects of methylprednisolone treatment on the course of this disease.

Background: Poisoning is one of the major causes of seizure in emergency medicine. Because of the varying availability of drugs in different areas and insufficient control of the sale of some dangerous industrial substances, the causes of seizure in poisoned patients may be differ in our society. In this study, we examine the causes of seizures in poisoned patients in Iran, and their outcomes.
Methods: This retrospective and analytical-descriptive study investigated the sex, age, type of poison, presence and type of seizure, seizure treatment and outcome from the records of 2,220 hospitalized poison victims from 2001 to 2003 in poison emergency departments in Noor Hospital. Data was analyzed by one-way analysis of variance and chi square tests using SPSS.
Results: Of the 2,220 patient records examined, 66 patients developed seizure. Seizure was more common in men (33 patients), and most common in the 15-40 year age group (28 patients). The most common causes of seizure were tricyclic antidepressants (TCA) (39.7%), organophosphates (17.5%), carbamazepine (7.9%) and organochlorines (6.3%). However, status epilepticus was more common in organochlorine (25%), organophosphate, TCA (18.75%), and carbamazepine (12.5%) poisoning. There was a negative relationship between age and type of seizures. Seizure was not related to previous history of seizure. Midazolam alone (25%) was the most effective drug for controlling seizures. Death occurred in six patients with or without renal complication. The mortality rate among poisoned patients with seizure was 37.5%.
Conclusion: The incidence of seizure in our study reflects the availability of certain drugs and toxins that require more steadfast control. Midazolam, with its low side effects, may be the drug of choice for the treatment of status epilepticus in poisoning.

Background: Sinus surgeries are usually associated with bleeding, thus can result in hemodynamic instability. This study investigated the hemodynamic changes induced by remifentanil plus isoflurane administration in comparison with propofol plus remifentanil in patients undergoing sinus surgery.
Methods: In this randomized clinical trial study, 96 patients were divided into two groups of isoflurane (1.2 MAC) plus remifentanil (44 patients, group A) and propofol (100 μg/kg/min) plus remifentanil (52 patients, group B). Twenty-two patients in group A and 23 in group B were male. The remifentanil dosage (0.1 μg/kg/min) was equal in both groups and all received 500 ml isotonic solution during the operation too.  Premedications and anesthetic inductions of both groups were similar. The variables included age, BMI, blood loss during surgery, systolic and diastolic blood pressures, pulse rate and mean arterial blood pressure.
Results: The mean age, BMI, amount of blood loss, mean systolic (30 minutes before and after the intervention) and diastolic blood pressures (60 minutes before and after the intervention), pulse rate (30 and 60 minutes before and after the intervention), mean arterial blood pressure (60 minutes before and after the intervention) were similar in both groups. The average mean arterial blood pressure, 30 minutes after the intervention (p=0.027) and the mean diastolic blood pressure, 30 minutes after the intervention (p=0.011) in the case group had statistically significant differences with the controls.
Conclusion: Based on this study, the combination of isoflurane plus remifentanil could better maintain the hemodynamic stability during sinus surgeries.

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Abnormal iron homeostasis such as iron deficiency or iron excess is associated with the pathogenesis of many chronic diseases including diabetes and cardiovascular disease (CVD). Iron may stimulate the progression of atherosclerosis by increasing the oxidative stress. Changes in carotid intima-media thickness (CIMT) have been validated as a vascular indicator of atherosclerosis progression. The purpose of this study was to apply CIMT to investigate the association between iron status and the initial stages of atherosclerosis.
Methods: 140 healthy premenopausal women aged 18 to 50 years who had no chronic or acute disease were selected randomly from one of the Tabriz university sub specialized clinics. Blood samples were taken to assay iron status parameters. CIMT was measured noninvasively by ultrasonography. Based on CIMT results, the subjects were classified as "healthy" (CIMT ≤0.8 mm) or "at risk" (CIMT >0.8 mm). Student's t-test was used to determine the mean differences between the two groups.
Results: The mean±SD age of the participants was 32.76±8.1 years. The mean iron, ferritin, hematocrit and mean corpuscular volume (MCV) were significantly higher and the total iron binding capacity (TIBC) was lower (P<0.05) among the "at risk" group. However, there was no significant differences in red blood cell count or hemoglobin levels between the two groups (P>0.05).
Conclusion: Results of this study showed a relative correlation between iron status parameters and CIMT as the initial indicator of CVD. Regarding the contradictions found in the literature, more research is needed to clarify the situation.

Background: Cognitive problems in patients with post-traumatic stress disorder (PTSD) include poor concentration and impaired memory. Prevalence of PTSD in all aspects of life is 8% in USA. Regarding the importance of memory in functional levels, this study was performed to review memory status in these patients.

Methods: Fifty male war veterans with PTSD and major depression and 50 male non-veterans with depression participated in this study performed at psychiatric outpatient ward in Baqiyatallah hospital during 2008-2009. The patients met the DSM-IV diagnostic criteria. Depression severity, sex, age, educational level, and marital status were matched in both groups. A psychologist completed demographic and Mississippi questionnaires, PTSD checklist (PCL), beck depression Inventory and wechsler memory scale. The collected data were analyzed using SPSS software (version 11.0). A P-value smaller than 0.05 was considered significant.

Results: The mean age of the veterans and non-veterans was 43.9±4.7 and 42±9.4 years, respectively. Memory status did not differ between the two groups (P>0.05). There was no statistically significant correlation between duration and severity of PTSD with memory impairment (P>0.05). A negative correlation was found between personal and general information with re-experiencing in the veterans (P<0.05). Impaired memory was correlated with age greater than 45, educational level lower than high school diploma, severity of depression and longer participation in war.

Conclusion: Although both PTSD and major depression affected memory, but memory status did not differ between patients with PTSD and depression and patients with chronic depression.

Background: Personal characteristics such as gender, ethnicity, disability, age, goals and personal expectations and academic variables such as the number of classes and grades are among the factors that could have an important role in the development of student satisfaction. Besides these factors, the relationship between emotional intelligence (EI) and academic satisfaction has received little attention. Methods: This descriptive cross-sectional study was done in Tehran University of Medical Sciences, Tehran, 2013. Cluster sampling was applied in this study. First, faculties randomly selected from Tehran University of Medical Sciences then randomly selected classes from the faculties. Self-report and Barr-On's emotional Intelligence questionnaires were used to collect data and measuring the variables of educational satisfaction. Questionnaires were completed by students. Overall reliability test using Cronbach's alpha coefficient was 0.73. The cut-off point of questionnaires was considered 70. This means that scores below 70 points showed the low level of satisfaction and scores more than 70 points were considered as a high level of satisfaction. Results: One hundred sixty eight students participated in the study. Average emotional intelligence was 3.25±0.45, the scale of consciousness 3.44±0.59, the self-control scale 3.90±0.59, scale spontaneous 3.17±0.46, Social skills 3.30±0.59, social consciousness 3.24±0.67, satisfactory academic 96.55±14.66 respectively. There was a significant relationship between self-consciousness and educational satisfaction (P=0.002) but self-control variable did not significantly correlated with educational satisfaction (P=0.249). The results showed that emotional intelligence on academic satisfaction can be explained. A change in the variance in one unit emotional intelligence was as much as five unit of the variance student satisfaction in based on standardized beta coefficient. There is a positive and direct relationship between them. Conclusion: The promotion of education satisfaction will increase indirectly possibility of job satisfaction in students in the future. Our results showed self-awareness and motivation skills in students increase their educational satisfaction.
