Background: Leukemia and lymphoma demonstrate significantly incidence rates throughout the world and particularly in Iran they cause serious mortality and diagnosis and treatment expenditures for both families and the health system. Combined they account for about 11 percent of cancers in Mazandaran province, ranking number 2 in prevalent cancers. The purpose of this study was to provide a first general and specific description of leukemia and lymphoma in Mazandaran province. Materials and Methods: In this descriptive retrospective study, entire patient's data were reviewed which had confirmed diagnosis of leukemia and lymphoma with valid laboratory or pathology reports in the period 2001-2008. The data were collected by Babol health research site related to Tehran University of Medical Science. Incidence rates based on age groups, gender, city of residence and type of malignancy were calculated and analyzed. Results: In Mazandaran province, 1,146 cases of leukemia and lymphoma were encountered, 5.9 in 100,000 persons on average annually. The highest incidence rates were obtained at age of 70 or above (26.4) and the lowest at age of 0-9 (2.3).The incidence rates in males and females were 7.1 and 4.8 respectively with a ratio of 1.5. The highest incidence rate was in Babol (7.3) and the lowest was calculated in Neka and Tonekabon equally (1.5). According to the type of malignancy, non Hodgkin lymphoma, with 2.5/100,000 have the most incidence rate and myeloid leukemia with 1.8 had the lowest. Conclusions: The obtained findings indicate clear differences in incidence rates based on age, gender, residence, and type of malignancy. Therefore it's suggested that in addition to promote data collecting programs, research projects should be programmed to define leukemia and lymphoma risk factors in this province.

During the last few decades, fluid viscous dampers have been significantly improved in terms of performance and reliability. Viscous dampers dissipate the input energy into heat and the increased temperature may damage internal seals of the damper. As a result, thermal compensation is crucial for almost all fluid viscous dampers. In this study, while referring to the main working principles of the recently developed bypass viscous damper in Iran, a comprehensive case study is conducted on a RC building having diagonal braces equipped with such viscous dampers. Experimental results of a small-scale bypass viscous damper is presented and it is shown that the currently available simplified Maxwell models can simulate behavior of the bypass viscous damper with good accuracy. Using a case study, contribution of bypass viscous dampers to seismic behavior of structural and non-structural elements are investigated. A designed procedure is adopted to increase damping ratio of the building from 3% to 15%. In this way, reductions of 25% and 13% in the required concrete and steel rebar materials have been achieved. From nonlinear time history analyses, it is observed that bypass viscous dampers can greatly improve seismic behavior of structural elements and non-structural elements.

Management of Precancerous Cervical Lesions in Iran: A Cost Minimizing Study
Nahvijou, Azin,Sari, Ali Akbari,Zendehdel, Kazem,Marnani, Ahmad Barati Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.19
Background: Cervical cancer is a common, preventable and manageable disease in women worldwide. Objectives: This study was conducted to determine the cost of follow-up for suspicious precancerous cervical lesions within a screening program using Pap smear or HPV DNA test through the decision tree. Materials and Methods: Patient follow-up processes were determined using standard guidelines and consultation with specialists to design a decision tree model. Costs of treatment in both public and private sectors were identified according to the national tariffs in 2010 and determined based on decision tree and provided services (visits to specialists, colposcopy, and conization) with two modalities: Pap smear and HPV DNA test. The number of patients and the mean cost of treatment in each sector were calculated. The prevalence of lesions and HPV were obtained from literature to estimate the cost of treatment for each woman in the population. Results: Follow-up costs were determined using seven processes for Pap smear and 11 processes for HPV DNA test. The total cost of using Pap smear and HPV DNA process for each woman in the population was 36.1$ and 174$ respectively. Conclusions: The follow-up process for patients with suspicious cervical lesions needs to be included in the existing screening program. HPV DNA test is currently more expensive than Pap smear, it is suggested that we manage precancerous cervical lesions with this latter test.

Challenges to Promoting Population-Based Cancer Registration in Iran: a Workshop Report
Hadji, Maryam,Nahvijou, Azin,Seddighi, Zahra,Beiki, Omid,Mohagheghi, Mohammad Ali,Mosavi-Jarrahi, Alireza,Marnani, Ahmad Barati,Zendehdel, Kazem Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10
In December 2011, the Cancer Research Centre of the Cancer Institute of Iran sponsored a 3-day workshop on "Cancer Registration Principle and Challenges in Iran", which convened cancer registry experts. The objectives of the workshop were: to introduce standard cancer registration, to review the policy and procedure of cancer registration in Iran, and to review the best practices in the cancer registries in Iran. Challenges to cancer registration were discussed and recommendations were developed. The workshop was evaluated by participants for better organization of subsequent workshops. The objective of publication of this report is that based on Cancer in 5 Continents, many low- or middle-income countries do not meet the criteria for a standard population-based cancer registry (PBCR); on the other hand cancer is the most important cause of mortality and the essential part of any cancer control program is the cancer registry. Therefore this report focuses on problems and challenges of PBCR and provides recommendations which might help other developing countries to decrease their PBCR defects.
