Tumor dissemination via blood to distant organs is the main cause of death. Therefore, there is a critical need to set up sensitive methods for the early detection of circulating tumor cells(CTCs) and disseminated tumor cells(DTCs) in peripheral blood (PB) and bone marrow(BM) specimens of breast cancer patients. The aim of this research is to study the detection of micrometastasis using MUC2 in such patients.

In this study, PB and BM samples were collected from 50 breast cancer patients after operation and before adjuvant therapy. Mucin 2 (MUC2) was used as a tumor marker and its transcript level in the sample patients was analyzed using gene specific, quantitative real-time PCR reaction with SYBR Green technology. Samples from 20 healthy individuals were used as negative controls. HPRT was used as a reference gene.

MUC2 mRNA was detected in 8 (16%) of PB and BM samples. MUC2 mRNA was not detected in PB samples of healthy individuals. The relapse rate among MUC2-positive patients was higher than MUC2-negative patients; and it was statistically significant in BM (P<0.05).

This study shows that MUC2 can be a suitable marker for the detection of micrometastasis in breast cancer patients at early stages of cancer and that it may provide the basis for identifying women at risk of relapse.

In strategic planning, there are several procedures to perform internal assessment or strength and weakness of organizations. Among other methods created for this purpose, Wiseboard model is the one in which the following six internal dimensions are considered: Organizational Structure, Leadership, Coordination, Reward System and Communication. This study measures three of these variables in hospitals of Tehran University of Medical Sciences (TUMS). This survey is a descriptive, analytical and cross-sectional study conducted during 2010 and 2011. The research population comprised all those working at TUMS hospitals from which a random sample of about 580 people was selected. The questionnaire's reliability was estimated to be 91% and the data were analyzed by the SPSS software. Of the subjects, 75.4% were below diploma level, 13% above diploma, 7.8% higher diploma, 66.4 bachelor holders, 2.6% master holders, and 5.4% had a doctoral degree or higher. Some 72.6% of the subjects were in Clinical and 19.8% in Nonclinical fields. The mean values of Goal Setting, Organizational Structure, and Leadership came out to be 24.47, 20.37, and 22.06, respectively. Based on the findings of this research study, TUMS hospitals have weaknesses in some aspects and they need improvement in some areas in the following order: Organizational Structure, Leadership, and Goal Setting.

Pityriasis versicolor is a fungal disease with causative agent Malassezia species which is an opportunistic and lipophilic yeast. With regard to liphophilic nature of the yeast, this study was carried out for evaluation of relationship between pityriasis versicolor and triglyceride and cholesterol levels This cross - sectional study was performed on 1500 subjects ranging from 10 to 50 years old in Isfahan province. Of total subjects, 105 had pityriasis versicolor. Disease confirmation was based on direct examination, inoculation and culture on Dixon media. Measurement of total cholesterol and triglyceride of patients and control groups in fasting manner was done by Auto analyzer RA 1000. Data of patients including age, education level and job was gathered by questionnaire and analysis of results was done by t student, chi square and Pearson correlation tests. Prevalence of infection was 7% in the test group. Maximum frequent rates of infection was %3.13 in age group 20- 30 years and minimum in age group 30-40 years(% 0.87). The highest rate of total cholesterol levels was seen in age group 40-50 years (mean 215 mg/dL) and the lowest was in age group 10-20 years(mean 205 mg/dL). Total cholesterol and triglyceride levels in patients were higher than the control group but the difference was not significant(P<0.05). No correlation was seen between pityriasis versicolor and increase in the total cholesterol and triglyceride levels in patients and control groups.

Internal Evaluation is a process of providing evaluative-descriptive information based on the value and significance of educational objectives, operations and results to direct decisions, responses, information and research processes.

In this research, studying the opinions of faculty members, students, and graduates, the educational system of Medical Laboratory Sciences Department at Tehran University of Medical Sciences (TUMS) was evaluated in the year 2010. The aim the study was to remodel and adjust the educational system with the society's needs and to promote the educational quality. The employed method was a cross-sectional, descriptive one and consisted of 10 procedural steps in eight sections dealing with the evaluated factors such as faculty members and students, and the satisfaction expressed by students.

The results of the study showed that the average of the eight investigated sections was 70.6% for the Department of Medical Laboratory Sciences, which can be interpreted as desirable.

Internal evaluation can be considered as one of the best methods of improving the quality of education in the faculty of Allied Health Sciences School

Health information System (HIS) is a comprehensive software used to unify and transfer hospital data effectively. It is vastly employed to improve input quality, decrease data-transfer time, increase satisfaction level, promote health services quality, and minimize hospital costs.

This is an applied-descriptive study. The research population consisted of 120 HIS users who worked before and after the HIS application at Masih-Daneshvari Hospital. For data collection purposes, a questionnaire was used. The data were then analyzed with SPSS software, and descriptive and inferential statistical methods.

According to data analysis, the application of the existing communication system among the different sections and wards was very good (81%), the accessibility to patient medical information and facilitating treatment processes were good (44% and 61%, respectively), and the analysis of budgeting data (11%), the possibility of clinical researches (19%), the presentation of guides for operators (18%), and the accessibility to statistical and financial data (17% and 22%, respectively) were assessed as poor.

The results of this survey show that the application of Hospital Information System has a positive effect on accuracy, facility, and treatment processes, and emphasize the importance of programming to enhance the quality of hospital services.

Although vancomycine is used for the treatment of methicillin resistant Staphylococci, but vancomycine alone might not be effective for the treatment of methicillin resistant Staphylococci in compromised host. In the same time antimicrobial activity of cefepim on gram positive bacteria especially Staphylococci is well known. In this study the synergism effect of cefepim and vavcomycin on positive and negative coagulase Staphylococci in vitro condition was investigated.

In total, 100 clinical samples of coagulase positive and negative Staphylococci were isolated from urine and blood samples from patients in Imam Khomeini Hospital during one year and identified. The modified Bauer-Kirby were used for the antibiotic susceptibility and macrodilution method for the MIC according to NCCLS procedure.

The results showed that after adding vancomycin to cefepime in concentration from 0.05+ 0.5, to 0.8+8, growth reduction reached from 3.5% to 100%.The synergism effect of the two mentioned antibiotics on coagulase negative Staphylococci resistant to methicillin were shown that from concentration of 0.05+ 0.5 to 0.8+8, a reduction in growth from 4.5% to 100% was observed.

The results of this study showed that vancomycin and cefepime has synergic effect on Staphylococci.

Work engagement is defined as a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption. Since the quality of care delivery to patients depends on nurse's practices, the objective of this study was to determine work engagement & its effective factors among nurses of general hospitals of Shiraz University of Medical Sciences. This cross sectional study was performed among 273 in-patient nurses of Namazi and Faghihi hospitals using 2 stages of sampling. Our questionnaire was validated by experts opinions and Cronbach's alpha index (86%). Descriptive statistics and correlation tests were used for the analysis of data by SPSS. According to the results obtained, mean work engagement was 58.95 ± 10.51 and there was a significant correlation between work engagement and organizational - supervisor support, organizational justice, job characteristics, reward & recognition, organizational citizenship behavior, organizational commitment, job satisfaction, turnover(p<0.05). The relationship between work engagement and reward was the strongest(r=0.512). The results imply the importance of work engagement and its related factors. Nurses are one of the biggest health system groups, and their burnout disadvantages hospitals and community. Thus, work engagement should be noticed in all policy-making related to nurses.

Problems such as hypothyroidism and aggressiveness may lead the organizations to reduced and seek to increase further behaviors that have the benefits for organization, such as productivity. One of the factors that produce productivity organization is organizational citizenship behavior. The aim of this study was to determine the relationship between the component of organizational citizenship behavior with human resources productivity among selected hospital's staff in Tehran University of Medical Sciences and Shahid Beheshti University of Medical Sciences. This research was carried out in 6 Hospitals of Tehran University of Medical Sciences and Shahid Beheshti University of Medical Sciences by attitude approach survey and data has been collected via questionnaire that was distributed among 429 staff of these hospitals by 2 stage stochastic sampling method. Research methodology has been descriptive, analytical and cross sectional. For survey to accept or reject the study hypothesis, was performed spearman correlation and regression tests with SPSS software. The study results showed that, in our population perception, there was a significant relationship between organizational citizenship behavior and productivity in people. This means that, in these hospitals, implementation of organizational citizenship behavior has effect on the amount of peoples productivity. In this study, the effect of magnanimity and look over component on productivity had different results in the studied hospitals. But results are same as the initiative of individual creativity component. In addition the potential reasons for probable low levels of these components and their related indices have been analyzed and the solutions have been presented for their improvement
