Introduction: Tachyarrhythmias in Wolf Parkinson White (WPW) syndrome, can be a life threatening factor. Antiarrhythmic drug therapy in this syndrome, has not been completely acceptable. Efficacy, safety and economy of Radio Frequency Catheter Ablation (RFCA) in western studies, has made it as the treatment of choice. In the present study, efficacy of RFCA in the ablation of accessory pathway(s) and also, its complication and recurrence rate were studied in Modarres Hospital, Tehran, Iran. Methods: In this clinical trial study, 63 patients with WPW syndrome and over 16 years old were selected. Accessory pathway(s) in Electrophysiologic Study (EPS) laboratory was confirmed and ablation with radiofrequency energy was performed. If successful, the patients were followed up for one year. The results were analyzed with Mc Nemar’s method and p<0.05 was considered significant. Results: Out of sixty three patients, 36 were male and 27 were female with the mean age of 38.4±14.9 years. The most common accessory pathways were in left free wall (52.4%) and then in septal region (31.7%), right free wall (9.5%) and multiple accessory pathways (6.3%). The success rate in the ablation of accessory pathways, in general, was 90.5%. Maximum success was in septal pathways (95%) and minimum in right accessory pathways (83%) and in multiple accessory pathways (75%). There was no meaningful relationship between efficacy of RFCA and age or sex. There was not any complication. The recurrence rate in a one year period was 4.8%. Conclusion: In this study, the result of RFCA in ablation of accessory pathway (s) and treatment of arrhythmia was comparable with previous western studies. So in our country, RFCA as the first therapy of choice in WPW syndrome is recommended.

Introduction: Congestive Heart Failure (CHF) is a pathophysiologic state in which an abnormality of cardiac function is responsible for the failure of the heart to pump blood at a commensurate rate with the requirements of the metabolizing tissues and/or allows it to do so only from an abnormally elevated diastolic volume. In this study, the prevalence of precipitating factors of CHF in Semnan, Iran is investigated. Methods: This is a cross-sectional study on all CHF patients who were hospitalized from April 2002 to May 2003, in Fatemieh University Hospital of Semnan. A pre-designed questionnaire including demographic characteristics of the patients, drug consumption method, clinical and para clinical findings, and the final precipitating factor of their heart failure, was completed for all patients and the results were presented using descriptive methods.Results: A total of 248 patients containing 130 females (52.4%) and 118 males (47.6%) were investigated. The most prevalent intensification cause of congestive heart failure was lack of patients’ compliance in taking medicine and nutrition regimen. Uncontrolled hypertension in 32.2% of the cases and acute coronary syndrome in 23.4% of cases were the other most prevalent causes of CHF.Conclusion: It seems that educating patients about their medicine and diet regimen will reduce the exacerbation factors of heart failure.

Introduction: Tooth decay is the most prevalent human disease after common cold. Although, fluoride in drinking water and daily meals can prevent teeth decay, its over consumption may cause fluorosis. This research was designed to study fluorosis prevalence rate in Bandar Abbas pupils, Iran.Methods: In this cross-sectional study, 867 pupils were randomly selected using a multi-stage sampling technique. Demographic characteristics of the pupils were collected and fluorosis degree based on Dean criteria was classified. Descriptive methods and t, ANOVA and Chi-Square tests were used for analysis and p<0.05 was considered as the significance level. Results: A total of 867 pupils were investigated. Mean fluoride rate for drinking water was 73% mg/l. Mild, moderate and severe fluorosis rate was 19.63%. The rates for male and female pupils were 18.9% and 19.26%, respectively. This difference was not statistically significant. Conclusion: High rate of fluoride in Bandar Abbas drinking water and high prevalence rate of fluorosis in pupils necessitate preventive measures and education programs for families.

Introduction: Aging may lead to increase or decrease in the level of total cholesterol, LDL and HDL. Furthermore, prevalence of thyroid dysfunctions increase with age in iodine sufficient area. The present study is designed to evaluate lipid profile and thyroid function tests in a group of elderly population in Hormozgan province.Methods: In this cross-sectional study, 60 (19 females and 41 males) elderly residents of Hormozgan elderly residence center were evaluated. After physical examination, the level of lipid profile and thyroid function tests were measured in fasting state. Kruskal-wallis and Mann-Witnney U test and Pearson correlation were used for statistical analysis. Results: The mean age and BMI were 66±11.6 years and 21.4±5.8 kg/m2. The BMI of men was greater than that of women p<0/05. Prevalence of obesity (BMI≥30kg/m) and low body weight (BMI<20kg/m2) were 10% and 25%, respectively. Prevalence of Hypercholesterolemia (≥240mg/dl). Hypertriglyceridemia (≥200mg/dl) and high risk LDL (≥160mg/dl) were 5%, 5% and 3.3%, respectively. Although aging led to decrease in level of TG, Cholesterol level and LDL in both sexes, BMI, HDL, cholesterol/ HDL and LDL/HDL did not show any change. There was no difference in lipid profile value between persons suffering from thyroid dysfunction and healthy population. Conclusion: Prevalence of Hypercholesterolemia, high risk LDL and hypertriglycemidia in this study was relatively low and it seems that aging, independent of BMI has a decreasing effect on level of some plasma lipoproteins. In contrast to other studies, the prevalence of thyroid dysfunction in this study (in an iodine sufficient area) was relatively low.

Introduction: Iron deficiency anemia is the most known form of nutritional deficiency in the world. It particularly occurs in women during .their fertility age. The current researches indicate that maternal iron deficiency anemia is associated with preterm delivery and low birth weight. This study was conducted to estimate the prevalence of iron deficiency anemia in pregnant women who referred to Dr. Shariati hospital in Bandar Abbas.Methods: In this descriptive-analytical study, 401 pregnant women were randomly selected. Hemoglobin, hematocrit, serum iron, serum ferritin, and red blood cell morphology of the patients were investigated and less than 11 gr/dl hemoglobin was considered anemia. For statistical analysis of the data, chisquare, Hest and logistic regression were used and p<0.05 was considered significant.Results: The results indicated that prevalence of anemia and iron deficiency anemia among subjects were 17.5% and 13%, respectively. The risk of iron deficiency anemia was 3.07 for those women who had pica during their pregnancy (p<O.OOI) and it was 2.19 for those women who had premature delivery (p<O.OOI). Based on the results, there was a significant relationship between iron deficiency and the number of bleeding days during menstruation (p<0.05).Conclusion: Iron deficiency anemia is a preventable disease and pregnant women are highly at risk of the disease. It seems that more preventive programs and pregnancy care can reduce the risk of the disease.

Introduction: Natural volcanic ash soil is one of minerals whose major contents are metal oxides. In this study absorption of copper (Cu2+) and nickel (Ni2+) on natural volcanic ash soil has been investigated at 27±1˚c as a function of PH, metal concentration, contact time and the amount of sorbet, using batch experiments. Methods: The necessary samples of natural volcanic ashes were collected from Anar region in Kerman province, Iran. The samples were analyzed by using quantitative and qualitative methods. In qualitative method, Gile’s classification and in quantitative method, Langmuir and Freundlich isotherms were used. Results: Both Langmuir and Freundlich models described the Cu2+ and Ni2+ absorption processes adequately, with correlation coefficient (R2) values ranging from 0.97-0.99. The results show that equilibrium is reached quickly, indicating that the adsorption sites are well exposed. The increase in initial metal ions concentration decreased the percent adsorption and increased the amount of metals uptake perunit weight of the sorbet (mg/g).Conclusion: The results indicated that the absorption capacity of the volcanic ash soil increased with an increase in the pH. The uptake of copper was found to be greater than nickel.

Introduction: Treatment is a complicated phenomenon which is influenced by a lot of factors. An important factor which directly affects patients' treatment is the relationship between patient and physicians. This study was conducted to investigate the expectations of patients from their physicians. Methods: The target population in this cross-sectional study was all patients who, for the first time, refer to internists, psychiatrists and surgeons. Fifty patients from each group were randomly selected. Before medical examination, they completed two separate pre-designed questionnaires. The first one was a demographic questionnaire and the second one was about expectations of the patients from physicians. The collected data were analyzed using statistical test for proportions.Results: The results showed that characteristics such as age, marital status, job, number of children and income have little or no significant effect on patients' expectations from physician. The only characteristics which significantly affect their expectations were sex and education level. Providing necessary information, matching the information with their education level, spending enough time to examine patients and providing information about drug side effects were other factors which were emphasized.Conclusion: Paying attention to patients' expectations has an effective role in their recovery. It seems that physicians management during medical examination and giving more information about the disease and the medications are effective in patients' satisfaction.

Introduction: The vital role of reproductive health in different aspects of human health and socio-economic development of the community on the one hand, and male teenagers’ knowledge about it on the other hand, necessitate priority setting and programming of health education. This study is conducted to investigate reproductive health knowledge level of male high school students in Shiraz, Iran. Methods: In this cross-section study, 360 high school male students studying in Shiraz high schools were randomly selected, using cluster sampling technique. All students completed a pre-designed questionnaire and the results were analyzed using SPSS statistical software. Results: Students’ knowledge regarding some items such as proper age for marriage of girls and the best age for pregnancy, was very good, but regarding some other information, such as contraception methods, the knowledge scores were very low and unacceptable. Among male contraception methods, condom was the most well known method, but, the female contraception methods were more familiar for them. Regarding sexually transmitted diseases, the students’ knowledge scores were low.Conclusion: In spite of acceptable knowledge of the students about some aspects of reproductive health, education programs, especially about sexually transmitted diseases are necessary.

Introduction: Premenstrual syndrome (PMS) and dysmenorrheal are experienced by majority of women in reproductive age and in 1% of the women it is severe enough to interfere with social interaction and work performance. Many investigations on treatment of this problem, in particular on treatment with chemical drugs, have been carried out. The aim in this study is to find whether or not herbaceous drugs such as Fennel and Chamomile, which are generally used in traditional medicine, are effective in treatment of dysmenorrheal and PMS. Methods: In this clinical trial study, 60 women over 16 years of age with a convincing history of premenstrual syndrome were randomly selected and their PMS and dysmenorrheal experiences were investigated in 5 menstruation cycles. During the 1st cycle, they didn’t take any medication, during the 2nd and 3rd cycles they took Fennel extract and during 4th and 5th cycles, they took Chamomile extract. After each cycle they completed a questionnaire containing 16 PMS symptoms. Friedman statistical test was used to compare the results from different cycles. P<0.05 was considered significant. Results: Based on the results, there was a significant difference between severity of symptoms in the control cycle, and other cycles in 3 of the 16 PMS symptoms (p<0.05). These three symptoms were pelvic and abdominal pains, fatigue and lethargy, depression and anger. As for other symptoms, the severity in the Fennel and Chamomile herbal drugs cycles was less than that of the control cycle, but this difference was not statistically significant. Conclusion: According to this study, Fennel and Chamomile are effective in reducing some PMS disorders. Fennel is more effective in pelvic and abdominal pain and depression but Chamomile is more effective in fatigue and lethargy.

Introduction: Oxyuriasis is an important parasitological diseases especially in children. The most striking symptom of the infection is pruritus. Some other symptoms are nocturia, sleepiness, insomnia, nightmares, intestinal pain and convulsion. Since the female worms migrate to annus to deposit their eggs, stool exam is usually negative for worms egg, but scotch tape test is the best method to demonstrate the infection. This study tried to detect oxyuriasis rate in Isfahan kindergartens. Methods: In this descriptive study, using stratified sampling method, 261 children were selected from 13 different regions of the city. Graham method was taught to the children’s parents and they did Graham test and filled in a pre-designed questionnaire. After microscopic investigation of the samples, the results were analyzed using SPSS statistical software. Results: 252 samples were collected from 13 different kindergartens of the city. Only 6 (2.38%) cases were infected by oxyure (4 boys and 2 girls). The cases were observed in 3 different kindergartens. Conclusion: The oxyuriasis infection rate was 2.38% which is significantly lower than the rates from previous studies. This result shows that oxyure infection in Isfahan kindergartens has reduced in recent years.
