ESOPHAGEAL CANCER AND TYPE OF FOOD AND BEVERAGE CONSUMPTION

Abstract Objective-The high prevalence of esophageal cancer (EC) in northern Iran, along with its unknown etiology, continues to be a major public health problem. Ecological and casecontrol studies have discussed the probable role of dietary factors in this disease. The aim of this study was to determine the relationship between EC and the type and characteristics of consumed food and beverages at the time of the study as well as in the past. Results-There were no significant differences between the case and control groups in respect to the age, sex and ethnic origin. The case group showed significant differences in family history of cancer other than EC, history of gastroesophageal reflux, habit of rapid drinking of hot tea, and eating of hot foods. These factors were found to be related to the presence of EC, whereas eating cheese, vegetables, fresh fruits, black pepper and turmeric were found to be protective factors. Methods-A Conclusion-This study showed some differences in the diet content and habits of patients suffering from EC in comparison to normal controls. Further elaborate studies are required to reveal the true pattern of dietary divergence in these patients. Besides, the authors are aware that recall bias might have distorted some of the results. More objective measures for assessment of diets are recommended

ASSESSMENT OF IMMUNIZATION COVERAGE IN IRAN

In an effort towards complying with the WHO,s global policy of achieving Health For All by the year 2000 and also with the pledge made by the Government of Iran to that effect, a national headquarters has been set up to speed the implementation of the Expanded Programme on Immunization (EPI) in the country. This paper aims to report the results of evaluations made at various times since the beginning of the implementation of EPI in 1983

Deltamethrin-impregnated bed nets and curtains in an anthroponotic cutaneous leishmaniasis control program in northeastern Iran

<b>Background: </b> Anthroponotic cutaneous leishmaniasis (ACL) has long been a significant public health prob-lem in northeastern Iran. The objective of this study was to determine the efficacy of deltamethrin-impregnated vs. nonimpregnated bed nets (NIBs) and curtains (NICs) in ACL control. <b> Patients: </b> Deltamethrin-impregnated bed nets (IBs) and curtains (ICs) with 25 mg ai/m²were distributed among 160 households in one district and NIBs and NICs were distributed among the same number of households in another district. A third district with a similar numbers of households served as a control. Health education mes-sages were disseminated to ensure the population&#x2032;s complicance with the proper use of bed nets and curtains. Sticky paper traps were used to assess the effect of insecticide-impregnated bed nets and curtains on the density of Phlebotomus sergenti. Deltamethrin susceptibility and also bioassay tests were carried out on the species by WHO standard method. Case findings were done by house-to-house visits once a season and all the inhabitants of the selected households in each district were examined. <b> Results: </b> IBs and ICs provided good protection against sandfly bites and reduced the transmission of ACL in the intervention district, while NIBs and NICs provided no protection. There was no significant difference in monthly density of P. sergenti indoors and outdoors among the districts (P>0.05). This species was susceptible to delta-methrin in the field population in the area. Bioassays confirmed that the nets treated with deltamethrin remained effective for more than 3 months. <b>Conclusion: </b> Personal protection is an effective and sustainable means of preventing and controlling ACL and can reduce dependence on insecticides. We encourage the use of IBs and ICs to control ACL in other high-risk areas of Iran and Afghanistan during the active season of sandflies

Determination of Malaria Epidemiological Status in Iran’s Malarious Areas as Baseline Information for Implementation of Malaria Elimination Program in Iran

Background: According to willingness of the Ministry of Health, Iran and presence of appropriate conditions for disease elimination, national malaria control program decided to conduct a research to clarify malaria status in 2007 and to provide required information to perform the elimination program. This review is comprised of the basis of national malaria elimination program in vision of 2025, which was started in 2010.Methods: In this descriptive study, data were analyzed by applications of different variables at district level. All districts in the three south eastern provinces, in which malaria has local transmission, were considered. Malaria cases has been determined and studied based on the national malaria surveillance system.Results: Since vivax malaria is predominant in Sistan & Baluchestan Province, number of vivax cases is equal to malaria positive cases approximately. The important point is that Nikshahr contains the maximum number of local vivax cases in this province and the maximum number of falciparum cases is reported from Sarbaz district. Among all districts of Hormozgan Province, no case of autochthonous falciparum was detected except in Bandar Jask and one case in Minab. There was no case of autochthonous falciparum in Kerman Province, except in Kahnoj and Ghale Ganj that each of them had one case in 2007.Conclusion: It appears that the report of locally transmitted cases in Iran is increasing over the past few years, before starting malaria elimination plan. Since the Afghan refugees started to return to their own country so the main source of reporting of imported malaria cases reduced and local cases would be demonstrated more clearly

Guinea worm (Dracunculiasis) eradication: update on progress and endgame challenges

The International Commission for the Certification of Dracunculiasis Eradication (ICCDE) met in December to review progress towards eradication. The status of the programme was presented by WHO and The Carter Center, Atlanta. The Commission received reports from international certification teams that Cote d'Ivoire, Niger and Nigeria were free of transmission and should be certified, while four countries, namely Chad, Ethiopia, Mali and South Sudan, remained endemic. The Commission certified that Somalia and South Africa were free of transmission. During 2013, there was a decline of about 78% in the numbers of cases reported in South Sudan. A report of the perplexing dracunculiasis epidemiology in Chad was also discussed, where dogs have been found to be infected with Dracunculus medinensis

The LHCb upgrade I

International audienceThe LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger than that of the previous running periods. Readout of all detectors into an all-software trigger is central to the new design, facilitating the reconstruction of events at the maximum LHC interaction rate, and their selection in real time. The experiment's tracking system has been completely upgraded with a new pixel vertex detector, a silicon tracker upstream of the dipole magnet and three scintillating fibre tracking stations downstream of the magnet. The whole photon detection system of the RICH detectors has been renewed and the readout electronics of the calorimeter and muon systems have been fully overhauled. The first stage of the all-software trigger is implemented on a GPU farm. The output of the trigger provides a combination of totally reconstructed physics objects, such as tracks and vertices, ready for final analysis, and of entire events which need further offline reprocessing. This scheme required a complete revision of the computing model and rewriting of the experiment's software
