Abstract
Background: An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. Outliers sometimes deal with to abnormality in obtained results from collected data and information. known outlier data by researchers, physicians and other persons that work in medical fields and sciences is important and they must control data before getting result about outlier data, effect of them in information bias and how to remove & control to obtain minimum bias and exact data .in this paper we had trying by known technique and tests to control them and minimized the errors related to them.
Methods: This paper has been done on 30 student's height in Tarbiat Modares University that measured by meter in smoothing area. We applied some methods such as Z-test, Grub test and graphical methods to determine outliers. In this paper the advantage and disadvantage of methods were evaluated and finally compares with each other.
Results: The above tests showed that the data values 153, 110 among collected data were outliers. All of the methods showed that the above data were outliers. Calculation quartiles and intermediate quartiles showed that the observations under 125 and upper 141 were mind outliers and if the observation under 119 and upper 147 is the sever outliers. According to upper situations the amounts of 110 and 153 is the sever outliers and resulted from all methods.
Conclusion: The results showed that all methods were useful in determine outlier data and between them Quartiles were important to known severe and mild outliers. Also Grub test with p-Value is very useful to report outliers.

Background: Gastric cancer is the second most common cancer and known
as the second cause of death due to cancers worldwide. Adenocarcinoma is the
most fatal cancer in Iran and a patient with this kind of cancer, has a lower
lifetime than others. In this research, the survival of patients with gastric
carcinoma who were registered at Taleghani Hospital, were studied.
Methods: 291 patients with Gastric carcinoma who had received
care, chemotherapy or chemoradiotherapy, at Taleghani Hospital in Tehran from 2002 to 2007 were studied as a historical cohort. Their survival rates and its
relationship with 12 risk factors were assessed.
Results: Of the 291 patients with Gastric carcinoma, 70.1 percent were men and others (29.9%) were women. The mean age of men
was 62.26 years and of women was 59.32 years at the time of diagnosis.
Most of patients (93.91%) were advanced stage and
metastasis. The Cox proportional hazards model showed that age at diagnosis,
tumor stage and histology type with survival time had significant relationships
(p=0.039, p=0.042 and p=0.032 respectively).
Conclusion: The five-year survival rate and median lifetime of
gastric cancer patients who underwent chemotherapy or chemoradiotherapy are
very low and seems that one of the important reasons for this situation is delayed diagnosis. The
scheme of public education about the early warning signs of the disease and
diagnosis and administration of periodic examinations is unavoidable.

Abstract
Background: Primary cutaneous lymphoma is separated into two groups, cutaneous lymphoma (CTCL) and cutaneous B-CELL Lymphoma (CBCL). This study was performed to classify histopathologically and define demographic features of Persian patients with primary cutaneous lymphoma.
Methods: Twenty hundred and thirty four patients with primary cutaneous lymphoma who have been referred to Razi Hospital in Tehran, Iran during at four year period (October 2005 to October 2009), were investigated in this study. The data were gathered by reviewing their medical records andexaminedagain extant evidence andhistology slides.
Results: Among 234 Patients, the only clinical feature that could be assessed was itching. The most common involves location of disease was generalized. 189 (80.77%) cases of the patients had CTCL and 45 (19.23%) cases of the patients had CBCL. Age of patients with two lymphoma type were similar at the this time of diagnosis. Sex supremacy was with men in two groups.
Conclusion: This study provides histopathologic classification and demographic data.

Abstract
Background: The preparedness and safety of hospitals in disasters are essential to maintain the health and survival of the community. Numerous studies have shown that the level of preparedness of Iranian hospitals is moderate and low. Lack of comprehensive hospital standards for disaster preparedness is one of the reasons. This study aimed to develop hospital accreditation standards for hospital disaster risk management.
Methods: This comparative study was conducted between April and September 2016. Hospital disaster risk management accreditation standards were extracted from the hospital accreditation standards of 11 countries including the United States, Canada, Australia, Malaysia, India, Thailand, Egypt, Turkey, Saudi Arabia, Denmark and Iran. Overall, 27 hospital disaster risk management accreditation standards were introduced. The opinions of 22 disaster risk management experts were used to assess the content validity of the proposed disaster risk management accreditation standards.
Results: Differences were observed in the quality and quantity of those countries’ disaster risk management standards. The national accreditation standards of the United States, Australia, and Canada had comprehensive standards and covered all aspects of the disaster risk management cycle. Finally, 27 standards were proposed for developing Iranian hospitals’ disaster risk management accreditation standards. The CVI & CVR validity of the proposed standards were acceptable.
There were significant differences in the quantity and quality of hospital disaster risk management accreditation standards in selected countries. The most comprehensive standards belonged to the US National Standards (12 standards and 113 sub-standards), followed by the Australian and Canadian accreditation standards. The accreditation standards of the developing countries and Iran were not comprehensive and did not meet the international goals of disaster risk management. The proposed hospital disaster risk management accreditation standards had high content validity.
Conclusion: Disaster risk management accreditation standards in Iran and developing countries need to be revised and upgraded. Comprehensive standards based on international experiences and expert opinions were introduced in this study that can be used to develop hospital accreditation standards in Iran and other countries.
