Background: Human papillomavirus (HPV) is the primary cause of cervical cancer, with HPV genotypes 16 and 18 classified as high-risk types. In Mongolia, HPV testing has been increasingly implemented in recent years, alongside updates to the national screening program. These developments highlight the need for additional testing approaches to encourage regular participation in the national screening program, improve diagnostic accuracy, and facilitate timely treatment planning. These considerations provided the rationale for this study. Aim: To detect HPV infection in cervical samples collected by healthcare professionals and vaginal samples self-collected by women, determine the concordance between the test results, and evaluate the feasibility of self-sampling for cervical cancer screening. Materials and Methods: A total of 206 women aged 25–68 years participated in the study. Two types of samples for HPV testing and one sample for PAP smear were collected from the participants. 14 high-risk of HPV genotypes were classified into three groups, and cytological findings were evaluated according to the 2014 Bethesda System. Statistical analyses were performed using SPSS version 30.0. Results: The concordance between the two sampling methods for HPV detection kappa was 0.949. High-risk HPV genotypes were detected in 50 women (35.2%) among the participants with available test results. Cytological abnormalities were identified in 51% of women who tested positive for HPV. Conclusion Self-sampling is a reliable method for HPV detection, demonstrating good concordance with healthcare professional-collected cervical samples. It has considerable potential to increase cervical cancer screening coverage and improve access to screening, particularly in geographically remote areas.

In Europe, colorectal cancer (CRC) is the second most frequent malignancy and the second commonest cause of death from cancer. -The prognosis of CRC patients is dependent on the stage of disease at the time of diagnosis. Contrast-enhanced computed tomography (CT) examinations allows simultaneous assessment of tumor’s local staging, estimation of its possible invasion into neighboring organs, and detection of nodal and distant metastases; which is essential for appropriate treatment planning and estimation of its outcomes. The lack of reports on CT findings in CRC in Mongolia, increase in CRCmorbidity, and significant potential benefits of early detection served as background for this study.We investigated subjects with histologically proven adenocarcinoma who underwent CRC-related operative treatment either at National Cancer Center, First State Central Hospital, or Ulaanbaatar Songdo Hospital (UBSH) in 2009-2012. We retrospectively reviewed and analyzed from the UBSH’ database their preoperative CT, colonoscopy, surgical and pathohistologic reports using PACSPLUS,OCS operation systems. CECT examinations were performed at Siemens Somatom 64 multidetector scanner.Countrywide, 111 patients underwent surgery for colorectal cancer in 2009-2012. Totally, we involved86 subjects, whose age ranged from 25 to 87 years (mean 61.3years ±13.7SD). The F: M= 48 (55.8%) :38 (44.2%).The CECT determined T2 staging in 10/86 (11.6%),T3 in 61/86 (70.9%); T4 in 15/86 (17.4%);a significant difference in T-staging between CECT and histopathological examination (х2=41.28, p=0.00 (p<0.05)) was found. The CECT detected no peritumoral lymphadenopathy (N0) in 39/86 (45.3%), N1 in 18/86 (20.9%) and N2 in 29/86 (33.7%) patients; there was a significant difference in N-staging between CT and histopathological evaluation (х2=17.74, p=0.007(p<0.05)). For T-staging, CECT evaluation yielded sensitivity of 50% in T2 , 83.6% in T3, 71.4% in T4 staging; Diagnostic accuracy of CT for T2 staging was 89.7%, for T3- 78.2%, for T4- 88.7%. For N-staging, CECT had sensitivity of 88.2%, specificity of 64% and accuracy of 73.8%.Preoperative colorectal cancer patients in Mongolia receive initial MDCT in late stage. The similarsensitivity in staging of T-parameter to that of the international comparable studies. Nodal heterogeneity on CECT was more sensitive for nodal metastases than the size.

IntroductionThere are an estimated 246 million people with diabetes mellitus globally and this figure is predictedto rise to 380 million by 2025, with the most rapid growth in developing countries, among the workingage group of the population.Now in Mongolia, the more than half of population live in cities and settlements, following thisurbanization the population`s diet and lifestyle has been changed to more western style and morepeople affected by diabetes mellitus.Diabetic retinopathy is the most common chronic and devastating complication of diabetes whichleads to visual impairment and blindness. Diabetic retinopathy develops in nearly all persons withtype 1 diabetes and in more than 77% those with type 2 who survive over 20 years with disease. Thecurrent estimates of the prevalence of diabetic retinopathy vary in different countries. The WHO hasestimated that diabetic retinopathy is responsible for 4.8% of 37 million cases of blindness throughoutthe world.Significant independent predictors of proliferative diabetic retinopathy determined by multivariableanalysis were fasting plasma glucose level, duration diabetes, plasma cholesterol, systolic bloodpressure and therapeutic regimen.In recent years a number of randomized clinical trials have shown that interventions to improvemetabolic control, careful monitoring and treatment reduce late diabetic complications.GoalTo establish the prevalence, severity and risk factors of diabetic retinopathy type 2 diabetic patientsin Ulaanbaatar.Materials and MethodsThe study conducted by cross sectional study. Randomly selected 235 patients type 2 diabetic patientsfrom Bayanzurh districts of city Ulaanbaatar. Participants provided a detailed medical and personalhistory, underwent an ocular examination including funduscopy. Fasting blood glucose-FBG, totalcholesterols, triglyceride, HDL were determined by methods of laboratory in venous plasma.ResultsThe prevalence of diabetic retinopathy among people with type 2 diabetes was 37.4%. The prevalencenon-proliferative diabetic retinopathy was 17% (40), pre-proliferative diabetic retinopathy was 8.1%(19), and of proliferative diabetic retinopathy was 12.3 %( 29).The mean age of participants with diabetic retinopathy was 57.4 years (range 26-79). The meanage of participants with non-diabetic retinopathy was 53.6 years (range 26-76). The prevalence of diabetic retinopathy did not vary significantly with age. Retinopathy was positively associated with alonger reported duration of diabetes and with higher fractions of blood glucose (p<0.05).Progression of diabetic retinopathy positively associated with high level fasting blood glucose (6.2mmol/l), total cholesterol (4.5 mmol/l), systolic pressure (130 mm Hg) diastolic pressure (90 mm Hg),triglyceride (2.2 mmol.l) and low level HDL (1.1 mmol/l).ConclusionRisk factors for diabetic retinopathy were found to be high level of blood glucose, longer duration ofdiabetes. Diabetes poor control was significantly associated with progression of diabetic retinopathy.

Background An impotant step in maintaining smile to replace missing teeth. When teeth are missing, the remaining ones can change position, drifting the surruonding space. Teeth that are out of position can damage tissues in the mouth. A denture helps you properly chew food, a diffi cult task when you are missing teeth. In addition, a denture may improve speech and prevent sagging face by providing support for lips and cheeks. A partial denture is suitable for those who have some natural teeth remaining.While missing one and two adjacent teeth can often be best restored fi xed bridge or implant, partail denture work best to replace multiple missing teeth. Removable partial denture usually consist of replacement teeth attached to pink or gum- colored plastic bases, which are connected by framework. Removable patial dentures attach to your natural teeth with metal clasp or devices called precision attachment. Precision attachments are generally more estetic and cost more than those metal clasps. Denture with metal and wrought wire clasps are generally more fi t and stay in place much better than (provisional) denture. Objective The main purpose of this study is to develop of provisional denture. Materials and Methods This study has been used to study medicine. Enerel dental clinic served 1481 people whom they were made denture between 2003 and 2005. from those people were made denture with wrought clasp for 60 people. By experimental study, jawing activity test has been used by I.S.Rubinov method. Results Denture with wrought clasp needs was increasing gradually until 56 percents in 2003, 82.1 percents in 2004, 93 percents in 2005. A large number of denture with wrought clasp was made 32.4 percent of maxilla, 47.1 percent was mandible but this denture were used and suited for people 78 percent, 22 percent of people who made those type of denture did not and uncomfortable for them. Denture with wrought clasp jawing activity was 1.920.13 seconds and jawed things weight was1.89 0.1, lost of jawing activity was 2.691.44 (=0.001). Conclusion Method of denture with wrought clasp is simpler and nearly minted removable denture.
