Background: In a study conducted in the United States, there is a possibility of negative health effects due to risky behavior. Most smokers (88%) started using tobacco before the age of 18years. In recent years, the use of e-cigarettes has increased in Mongolia, which can be seen by the fact that someone around us is using them. All tobacco products are addictive and involve risky behaviors. Risky behaviors are behaviors that pose a risk of harming one’s own or others’ health, causing morbidity or mortality. Therefore, there is no study on the level of smoking dependence and risky behavior among students, which is the basis of our study. Aim: The study is aimed to evaluate the risky behavior and cigarette smoking among students who are studying the school of university Material and Methods: The study was conducted by using a cross sectional design and a quantitative research method. All students of the School of Nursing, MNUMS were included. First to fourth course students of nursing school were included on a voluntary basis. Results: In the study, 87.8% of participants were female and 12.2% were male student. Furthermore, 50.2% of respondents are smokers. When the physical nicotine dependence test was taken from smoking students, moderate to high levels of dependence were identified, indicating there is behavioral risk. Risk behaviors are associated with factors such as safety, violence, bullying, feelings of sadness, use of tobacco and drugs, consumption of alcoholic beverages, changes in sexual orientation, and body weight. Conclusions 1. The students have limited scientific understanding and explanation regarding tobacco use. 2. Among the study participants, 5.4% had a very low level of dependence, 34% had a low level, 24.3% had a moderate level, 35.6% had a high level, and 0.54% had a very high level of dependence. 3. Risk behaviors related to health include tobacco use, alcohol consumption, marijuana use, bullying and violence, sexual activity, feelings of sadness or suicidal thoughts, screen dependence, and consumption of cola beverages.

Background: Acute appendicitis is an inflammatory disease and acommon cause of acute abdominal pain. The application of the sophisticated automated hematology analyzer more precisely define the morphology changes blood cells. According to this diagnose and treatment control issues are solved by easy and not expensive way. Recent studies haveshown that there is a negative correlation between platelet count (PC) and MPV and that theratio of these two values may be more meaningful. The aim of our study was to investigate thediagnostic value of MPV and the MPV/PC ratio in acute appendicitis. Methods: The patients were divided into two groups based on their histopathological findings: the uncomplicated and complicated appendicitis groups. Leukocyte count, PC, MPV and the MPV/PC ratio were compared all groups. Results: Total of 186 patients, including 119 men, were included in the study. The average age of all patients was 10.21±1.22 years. There was statistically significant difference of some parameters in peripheral blood between the uncomplicated and complicated appendicitis groups in terms of all index. (p<0.001). Leukocyte count had a strong discriminatory property based on the area under curve (AUC) 0.714, (p<0.001). MPV, PC and the MPV/PC ratio had weak discriminatory power with AUC values <0.663. Using receiver operating characteristic (ROC) analysis, the sensitivity and specificity of MPV were 81.56and 45.7%, respectively, and 63.78% and 71.06%, respectively, for the MPV/PC ratio. Conclusions In our study, MPV and the MPV/PC ratio were useful in the diagnosis of acute appendicitis.

Result the subtypes and effectiveness of functional endoscopic sinus surgery(FESS) using a microdebrider Introduction: Chronic rhinitis in children has been on the rise in recent years, and polyps account for the majority of benign nasal cancers in children. Surgery is necessary when drug treatment is ineffective. We use pediatric rhinoplasty. Aimed at calculating the subtypes and effectiveness of Functional endoscopic sinus surgery(FESS) using a microdebrider. Material and methods: The survey was conducted between March and April 2020, based on the Otolaryngology Surgery Department of the National Center for Maternal and Child Health, using the cross-section of analytical design under Objectives 1 and 2 and the longitudinal design under Objective 3. Under Objectives 1 and 2, participants' information was collected from a pre-prepared questionnaire from their medical history. The questionnaire has four chapters that provide general information about the patient, clinical signs, surgical structure, and biopsy results. The pain was assessed by the “Sino-Nasal Outcome Test (SNOT-20)”. A total of 98 patients were included in the statistical analysis of the survey results using the STATA 15.0 program, and the results of the surgery were evaluated by 20 patients. Results: In children with chronic rhinitis, the SNOT20 test showed a statistically significant difference of 1.6 ± 0.6 before surgery and an average of 0.51 ± 0.11 after surgery. Conclusion: In chronic rhinitis, FESS with microdebrider surgery is an effective treatment for children.
