Abstract
Background: post operative pain is an essential problem. Epidural infusion of two different doses of bupivacaine in pain management of post orthopedic surgeries was studied.
Methods: In this double blinded randomized clinical trial we studied two groups of 42 patients undergone knee surgery. Based on block randomization, patients received two different concentration of bupivacaine (0.1% or 0.125%) in combination with fentanyl (1.7µg/ml). The beginning infusion rate was 5ml/h. Pain scores were documented by a blinded researcher 6, 12, 18, 24 and 48 hours after completion of surgery according to VAS tool. Patient satisfaction, complications and treatment failure (when increased volume of epidural infusion or other analgesics were required) were evaluated.
Results: In higher bupivacaine dose group, post operative pain scores were not significantly lower in different hours and during the follow up (both p values less than 0.001). After 48 hours, patients satisfaction were more in the higher bupivacaine group. There were no significant differences in complications. Treatment failure was more significant in lower bupivacaine dose (33.3% versus 11.9%, p=0.03).
Conclusion: continuous epidural infusion of both bupivacaine and fentanyl provide acceptable post operative pain control in orthopedic patients. Although higher concentrations of bupivacaine during first hours are more effective, lower concentrations are as effective as the higher one, during subsequent hours.

Abstract
Background: Tuberculosis is still one of the main causes of mortality and disability in developing countries. Despite of socio-economic development of communities and controlling majority of communicable diseases, With respect to importance and high incidence of Tuberculosis in marginal provinces, the present study was aimed to assess the epidemiology of Tuberculosis.
Methods: In this Descriptive-Analytical Retrospective Study, documents of 6363 patients diagnosed with TB in the beginning of March 2005 to the end of the September 2012 in Khuzestan province, Iran, by used census sampling size, were used. Demographic variables and other necessity data were recorded by TB-Register software and then these data were analyzed by SPSS 16.0 software and Chi-square and independent t-tests with a significance level of less than 5%. For comparison Tuberculosis incidence in consecutive years used by Poisson tests (with a significance level of less than 5%).
Results: mean age of patients and median age of patients were 39.3±18 and 35±6.5 years, for women mean age was older 2.1 years than men and there was significant relationship to age (P=0.0001). Of all patients 75.7% were pulmonary tuberculosis, 2.7% were infected with HIV and 91.2% were new cases. Cumulative incidence in province was 148.84/100,000. Most prevalent in Non-pulmonary TB was Lymphatic glands. Poisson test showed that changing trends of TB incidence in study years was statistically significant (P<0.05).
Conclusion: Increasing concurrent of HIV infection and TB and decreasing patients mean age (39.3±18) and median (35±6.5) in southwest of Iran has high prevalence. Screening, training and preventive activities for controlling of disease is highly recommended for the whole country and in margin provinces in particular.

Abstract
Background: Distribution of Tuberculosis (TB) has a special template affected by geographic and social factors. Nowadays Geographical Information System (GIS) software is one of the most important and useful epidemiologic devise for identifying geographic areas and high risk population for infection by TB. Aim of this study was assessment of Tuberculosis distribution by GIS in Khuzestan province, Iran.
Methods: In this retrospective cohort study, documents of 6363 TB patients identified in Khuzestan province at the beginning of 2005 until the end of the September of 2012 were assessed and sampling method was census. The data was gathered by TB-Register Center. TB incidence was evaluated by GIS maps according to climatic and vegetation with 1:25,000 scale. The data was analyzed in SPSS software and means plot and Independent’s t-test, ANOVA with a significance level of less than 5% and Eta Correlation.
Results: Spread of Tuberculosis in climatic and vegetation were plotted in GIS maps, cumulative incidence rate was calculated separately for each area. There was a statistical significant relationship between cumulative incidence rate of disease and climatic (P=0.017) and the Eta correlation coefficient was 0.379 (P=0.011). There was a statistical significant relationship between cumulative incidence rate of TB and vegetation (P=0.004) and the Eta correlation coefficient was 0.388 (P=0.188). Mean age and median age of patients were 39.3±18 and 35±6.5 years respectively. For women, mean age was 2.1 years older than men and this difference was statistically significant. (P=0.0001).
Conclusion: The risk of TB infection is closely associated with the climatic and vegetation. So the risk of TB in extra-dry climate and vegetation of highland meadows is more than other areas. Special care and services to high-risk areas is recommended.

Abstract
Background: Asthma as an airway disease is identified by increase network respon-siveness of the trachea and bronchus to a specific stimulus. Th17 cells through produc-tion of IL-17 have important role in inflammation and autoimmune diseases .In some studies has been shown which IL-17 as major cytokine of Th17 probably has im-portant role in the pathogenesis of allergy and asthma.
Methods: Total mRNA extracted from whole blood samples and sputum of 23 asthma patients and 23 normal controls. Then, total RNA was converted into cDNA according to the manufacturer’s instructions. Finally, the transcript levels of IL-17 were quanti-fied by the real-time quantitative PCR. Twenty-three patients with asthma were diag-nosed and selected according to the global initiative for asthma (GINA) and none of the patients had taken the medication at least three week before sampling. Healthy in-dividuals did not have any history of allergy, asthma and other inflammatory diseases at the time of sampling. All of experiments have done in Isfahan University of Medical Sciences, Iran during May to February, 2013.
Results: This study showed a significant increase in transcript levels of IL-17 in the blood (287±79 versus 1/18±0/13) and sputum samples of the patients (64±28 versus 0/9±0/1) in comparison with normal individuals (P= 0.000, P= 0.029 respectively). It al-so revealed that the expression levels of the cytokines in the serum samples of the asthmatics were significantly more than their levels in patient’s sputum samples (P= 0.000). However, there was no significant difference between the cytokines expression levels in serum samples and sputum samples of the controls (P> 0.05).
Conclusion: In this study, we showed which the expression of IL-17 was increased in serum and sputum of asthmatic patients compared to healthy controls, this could re-sult in elevation of neutrophils population and activation of pulmonary neutrophil.
