Along with the global fervor over evidence based medicine (EBM), certain measures have been taken in Iran too. Many educational workshops and national and international seminars have been held. Multiple educational packages have been prepared and even included in the educational curriculum. In recent years, policies have been directed toward encouraging clinical guidelines, health technology assessment reports and policy briefs. Also, recently, the 'National Strategic Program in Evidence-Based Health Care in the Islamic Republic of Iran' has been defined by the Ministry of Health and Medical Education. In spite of all these efforts, studies that follow the uptake of evidence-based contents at the bedside show that EBM is not used in practice and at the bedside. The overall effect of the efforts mentioned is the knowledge promotion of the participants of the educational programs and or increasing their abilities in articles' critical appraisal; nothing has been added in the practice arena. It seems that, in Iran, EBM's current and future needs are to focus on its implementation, what is in other words called 'knowledge translation' or the application of scientific evidence.

The government of the United Republic of Tanzania has initiated the Integrated Management of Childhood Illness program to improve the health and wellbeing of children.Tanzania's under-five mortality rate is still 1.7 times higher than the world average and, in order to achieve its Millennium Development Goal 4 target, its annual reduction rate is quite low at 2.2. The main aim of the study is to examine under-five mortality combined with the Data from the Tanzania Demographic and Health Survey 2008 data was used. Odds ratios for infant and under-five mortality were estimated using logistic regression; crude and adjusting models were adopted.Mortality cases (18.3%) have been reported to children born with an interval of <24 months. Mothers with no education reported 14.6%, primary education mothers reported 11.1% and higher education reported only 5.3% (P<0.001). Therefore, maternal education plays is a major role on fertility and infant and under-five mortality behavior.Maternal education also influences a mother's behavior in her usage of available health services to improve the health of the children. Further in-depth analysis is immensely needed in this situation.

South Africa (SA) is experiencing a rapid epidemiologic transition as a consequence of political, economic and social changes. In this study we described, based on hospital data, the mortality patterns of Non communicable Diseases (NCD), Communicable Diseases (CD), the NCD/CD ratios, and the trends of deaths.We conducted a cross-sectional survey of all deaths occurring in several public hospitals in the Eastern Cape Province of SA between 2002 and 2006. Causes of deaths were coded according to the ICD 10 Edition.A total of 107380 admissions responded to the inclusion criteria between 2002 and 2006. The crude death rate was 4.3% (n=4566) with a mean age of 46±21 years and a sex ratio of 3.1 men (n=3453): 1 woman (n=1113). Out of all deaths, there were 62.9% NCD (n=2872) vs. 37.1% CD (n=1694) with NCD/CD ratio of 1.7. The ratio NCD/CD deaths in men was 1.3 (n=1951/1502) vs. NCD/CD deaths in women of 1.9 (n=735/378). The peak of deaths was observed in winter season. The majority of NCD deaths were at age of 30-64 years, whereas the highest rate of CD deaths was at age< 30 years. The trend of deaths including the majority of NCD, increased from 2002 to 2006. There was a tendency of increase in tuberculosis deaths, but a tendency of decrease in HIV/AIDS deaths was from 2002 to 2006.Non-communicable diseases are the leading causes of deaths in rural Eastern Cape province of SA facing Post-epidemiologic transition stages. We recommend overarching priority actions for the response to the Non-communicable Diseases: policy change, prevention, treatment, international cooperation, research, monitoring, accountability, and re-orientation of health systems.

A retrospective cohort study, in the context of household transmission, to estimate the serial interval (SI) of pH1N1 influenza in the island of Tierra del Fuego was carried out.We collected data from the epidemiological surveillance system during disease outbreak in Ushuaia and Rio Grande, the two main cities of the southernmost province of Argentina. Only the records of patients and households with a positive result of RT-PCR assay for pH1N1 virus were used.A total of 283 laboratory confirmed cases were detected, from 550 samples analyzed. Hospitalizations were necessary in 13.8% of patients, yet no deaths were reported. Complete data of household contacts were available in 13 patients. We calculated an SI of 2.0 days (95% CI = 1.5 - 2.6 days), fitting to a log-normal distribution, the one that presented the best adjustment.These results were consistent with estimates of SI calculated from Mexico, but lower than estimations from Canada, Germany and USA. We discuss these differences in relation to limitations of the current study design.

Substance abuse in adolescents and its often tragic consequences, including addiction, is one of the preventable major public health problems. The aims of this paper were to estimate the prevalence of substance abuse and to evaluate its some associated factors in adolescents of Tabriz City (northwest of Iran).A self-administered questionnaire was completed in 4903 randomly selected students with mean age of 15.7 years old. The aim of the questionnaire was obtaining information on substance abuse, socio-economical information, cigarette smoking behavior, general risk taking behavior, self-esteem, attitude towards smoking and self-injury as well as demographical characteristics.Prevalence of substance abuse was 1.4% (95% CI: 1.1-1.7) which was different statistically significant between boys (2.4%) and girls (0.6%) (P<0.001). Older age (OR=1.43), not living with parents (OR=2.34), having general risk taking behavior (OR=2.26), higher smoking stage (OR=2.39), lower self-esteem (OR=1.09) and positive attitude toward smoking (OR=1.08) were factors associated with student's ever use of substance.The result has shown low prevalence of substance abuse in Iranian adolescents. Our findings showed some associated factors such as lower self-esteem with adolescent's substance abuse.

Serum levels of zinc, copper, vitamin B12, folate and immunoglobulins in individuals with giardiasis
Giardia lamblia is one of the most important intestinal parasites. The aim of this study was to measure serum levels of IgA, IgE, zinc, copper, vitamin B12 and folate in individuals with giardiasis in comparison to normal subjects.The study was carried out among 49 Giardia positive and 39 age and sex matched healthy volunteers. Examination of stool samples was done by direct wet smear and formol-ether concentration method. Serum samples were obtained for further laboratory examination. IgA levels were measured by Single Radial Immune Diffusion (SRID). IgE levels were measured by ELISA kit. Zinc and copper levels was measured by Ziestchem Diagnostics Kit and colorimetric endpoint-method respectively. Vitamin B12 and folate levels were measured by DRG Diagnostics Kit and Enzyme Immunoassay method respectively. All data were analyzed using SPSS version 17.There was a statistically significant difference in IgA, IgE, copper and zinc levels between positive and negative groups (P<0.05). There was no significant difference between vitamin B12 and folate levels between the two groups. Mean values of Giardia positive and negative groups for IgA were 309.26 and 216.89 mg/dl, IgE 167.34 and 35.49 IU/ml, copper 309.74 and 253.61 μg/dl and zinc 69.41 and 144.75 μg/dl respectively.The results showed levels of IgA may correlate more closely with giardiasis than IgE. Regarding trace elements, giardiasis elevated serum copper levels, while it decreased serum zinc. Finally, there was no significant difference in serum levels of vitamin B12 and folic acid between the two groups.

In the previous studies, the rate of primary infertility was reported differently. It seems the main reasons are related to the different methods of data collection and information analysis. Therefore, introducing a precise method to determine the infertile couples and the population exposed to the risk of infertility is an important issue to study primary infertility.The proposed methodology for assessing primary infertility rate has been designed and applied by Avicenna Research Institute in a national survey. Sampling was conducted based on probability proportional to size cluster method. In this survey, after reviewing the former studies, the reproductive history was used as a basis for data collection. Every reproductive event was recorded with a code and a date in the questionnaire. To introduce a precise method, all possible events were considered thoroughly and for each situation, it was determined whether these cases should be considered in numerator, denominator or it should be eliminated from the study. Also in some situations where the correct diagnosis of infertility was not possible, a sensitivity analysis was recommended to see the variability of results under different scenarios.The proposed methodology can precisely define the infertile women and the population exposed to the risk of infertility. So, this method is more accurate than other available data collection strategies. To avoid bias and make a consistent methodology, using this method is recommended in future prevalence studies.

We estimated the prevalence of HIV, sexually transmitted infections (STIs), and risky behaviors among female sex workers (FSW) in Kerman City, Iran.Women, 18 years or older, who reported selling sex for at least 6 months during their lifetime and had at least one sexual contact with a client in the recent 12 months were sampled using Responding Driven Sampling (RDS). Participants were interviewed about their sexual behaviors and provided whole blood for HIV, syphilis, and Herpes simplex type 2 (HSV2) testing. Data were analyzed using RDSAT Version 6.0 software.Among samples of 177 FSW, we did not find any HIV positive cases. The weighted prevalence of syphilis and HSV2 were 7.2% and 18.0%, respectively. The reported STI syndromes for the proceeding year of the survey were 36%. Unprotected sexual contact was about 17-22% and link to injecting drug users through injection was about 18%.While this survey found no HIV, there were findings of risky sexual behaviors and STI, markers for potential infection for HIV. The prevalence of STI and sexual risk behaviors for HIV is considerably high in this subpopulation that alarming for an urgent public health preventive measures and national control-plan to be developed and implemented.

Computable general equilibrium models are known as a powerful instrument in economic analyses and widely have been used in order to evaluate trade liberalization effects. The purpose of this study was to provide the impacts of trade openness on pharmaceutical industry using CGE model.Using a computable general equilibrium model in this study, the effects of decrease in tariffs as a symbol of trade liberalization on key variables of Iranian pharmaceutical products were studied. Simulation was performed via two scenarios in this study. The first scenario was the effect of decrease in tariffs of pharmaceutical products as 10, 30, 50, and 100 on key drug variables, and the second was the effect of decrease in other sectors except pharmaceutical products on vital and economic variables of pharmaceutical products. The required data were obtained and the model parameters were calibrated according to the social accounting matrix of Iran in 2006.The results associated with simulation demonstrated that the first scenario has increased import, export, drug supply to markets and household consumption, while import, export, supply of product to market, and household consumption of pharmaceutical products would averagely decrease in the second scenario. Ultimately, society welfare would improve in all scenarios.We presents and synthesizes the CGE model which could be used to analyze trade liberalization policy issue in developing countries (like Iran), and thus provides information that policymakers can use to improve the pharmacy economics.

Stress is not always a direct result of stressful conditions, but rather the way they are perceived. Thus individual variables that may be associated with perceived stress should be examined in stress studies. This study investigates the intermediary role of self-efficacy in relation with stress, glycosylated haemoglobin and health-related quality of life in patients with type2 diabetes.All women with diabetes in Yazd Diabetes Research Centre, in 2012, were considered and 80 women were selected by random sampling. They completed Shirer's self-efficacy scale questionnaire, depression, anxiety and stress scale (DASS), and ADDQ0L19 questionnaire. Then they were introduced to the lab for blood test. Data were analysed by SPSS software and stepwise regression method.Pearson correlation test results showed that the hemoglobin A1c (r = 0.35) and Quality of Life (r = -0.22) are associated with stress (P <0.05). As so hemoglobin A1c (r = 0.83) and Quality of Life (r = 0.37) with variable of self efficacy are associated positively and significantly (P <0.05). Results of stepwise regression also showed that self efficacy and stress scales 0.697 of variance hemoglobin A1c and 0.140 of variance of Quality of life explaining to do.The impact of stress on blood sugar and patients' health-related quality of life can be influenced by their self-efficacy; therefore it is suggested that an educational intervention is done to increase patients' self-efficacy to better cope with stress in their life.

Visual sciences have been progressing quickly in recent decades through globalization phenomenon. An enormous change has taken place in ocular health issues, however, there are various problems facing ophthalmic public health worldwide. In the previous years, the World Health Organization and the International Agency for the Prevention of Blindness in partnership launched the global initiative to eradicate avoidable blindness by the year 2020, VISION 2020 the Right to Sight. It has concentrated on the prevention of blindness disability and recognized a health issue-sight as a human right. In view of challenges ahead of visual sciences, close collaboration between international agencies at the global level to implement new strategies and monitor the progress will be mandatory. In these circumstances non-governmental organizations should not be neglected. World Sight Day 2012 would be a great opportunity to be a focus on importance of visual impairment as an important public health issue and discovering new challenges ahead.

The aim of this study was to appraisal the effect of highly cited papers in the field of public health and find out whether the unusual citations affect the ranking order of the journals in this field or not. A total number of 142 journals titles were listed in Journal Citation Report (ISI Thomson) in the field of "Public, Environmental & Occupational Health". All but one of them had published papers at least for a year from 2009 to 2010. Journal title, number of citations and publication year of 45685 papers were collected from ISI web of knowledge database at December 25, 2011. About half of the papers (23226) had no citations and 89.4% (40835) had less than 6 citations. We concluded that the ranking of journals in the field of public health is not affected by the individual papers with unusual number of citations.

Brucellosis is a zoonotic disease mostly transmitted to humans through consumption of unpasteurized dairy products and can lead to a systemic disease with any organ involvement. In this report, we describe a case of brucellosis-induced avascular necrosis of the hip. Brucellosis was diagnosed through serological tests, and avascular necrosis of the femoral head was confirmed by pelvic MRI. The patient was treated with a combination of antimicrobial treatments and referred to the orthopedic service for total hip arthroplasty. Brucellosis may present with unusual manifestations and should be always taken into consideration, particularly in endemic areas.
