Abstract: Background: Colorectal cancer ranked the second cancers in the Kingdom of Saudi Arabia, accounting for 10.4% of all newly diagnosed cancers in 2010. There are several risk factors affecting the incidence of colorectal cancer where some factors influence the risk more than others. Colorectal cancer is easily preventable through screening which can detect the disease in its early stages and improve survival rates. Aim: We aimed to determine the level of knowledge, attitude and practice of colorectal cancer and its risk factors among mall adult visitors in Riyadh, Saudi Arabia. Methods: Across-sectional study was conducted in five randomly selected malls (120 from each mall were randomly recruited), using a modified validated questionnaire. Means, standard deviations, frequencies, percentages were calculated for the differences in the level of awareness among the study participants. Results: The response rate was 70% (55% were females and 45% were males). More than one-third of the participants identified cigarette smoking, family history of colorectal cancer and inflammatory bowel disease as risk factors for the disease. In addition, the majority of responses reported that screening tools are useful in colorectal cancer prevention and control. Conclusion: Implementation of awareness programs is needed to establish a strong link between the public, health centers and educational institutions to increase the level of awareness of colorectal cancer

Abstract: Mucoepidermoid carcinoma (MEC) is one of most prevalent carcinomas of salivary glands in which the histoathological grading is very important in treatment and prognosis. In this study we are going to compare mast cell density in different kinds of mucoepidermoid grading by Toluidine blue staining. Materials and Methods. Paraffin blocks of 19 cases of low grade and 21 cases of high grade mucoepidermoid carcinoma were selected and stained by toluidine blue.The number of mast cells were observed in two manners(absolute and ordinal).T student was used for absolute counting and Mann Whitney for ordinal counting. in absolute counting,we defined a number for counting, for ordinal counting, we defined an interval range for mast cell numbers. Results. In absolute Counting,the mean of mast cell density in low grade cases was 19.7+/-15.7and in high grade cases was 20.3+/-21.07and there was no significant difference between two groups(p=0.920). In ordinal counting, there was no significant difference between two groups in mast cell density(p=0.729). Conclusion. According to this study, the mast cell counting can not be used for histopathological grading of MEC

Abstract: Early diagnosis of biliary tract tumors is important in accurate staging, to choose the best possible treatment and improve their prognosis. Multidetector row Computed Tomography is an ideal method to evaluate patients with suspected biliary tract obstruction and thereby biliary tract malignancy. Aims and Objective: To evaluate the accuracy of Multidetector row Computed Tomography (MDCT) in evaluation of level of obstruction and to study the imaging features of various causes of biliary tract malignancy. Material and Method: MDCT of 40 patients with clinically suspicion of biliary tract obstruction were prospectively reviewed and only malignant causes were included in the study. Final diagnosis was based on endoscopic retrograde cholangiopancreatography, surgical and histopathological diagnosis. The MDCT diagnosis and final diagnosis was compared for level and imaging features of malignant lesions. Results: The sensitivity, specificity, PPV, NPV and diagnostic accuracy of MDCT in determining the level of malignant obstruction is 100%, 83.33%, 97.77%, 100%, 98%, and cause of malignant obstruction is 97.73%, 83.33%, 97.72%, 83.33%, 96%. MDCT with its high sensitivity and specificity values plays an essential role in the diagnosis of malignant tumors of biliary tract and for the evaluation of therapeutic options. Conclusion: MDCT has a vital role to play in biliary tract malignancy with its high degree of accuracy in establishing the level of obstruction and in defining the imaging features of the malignant lesions.
