Background
Mongolia has been undergoing an epidemiological transition since 1990s. As a result, lifestyle and health behavior related diseases such as cardiovascular diseases, diabetes, cancer and injuries are growing steadily and have become the leading causes of population mortality. According to the Mongolian STEPS Survey on the Prevalence of NCD Risk Factors (2009), the summary of combined NCD risk factors demonstrates that 1 in 5 (26.4%) Mongolian adults have three or more common
modifiable NCD risk factors and consumption of alcohol in the past 30 days was reported by 38.6% of the population.
Goal
The goal of the survey was to determine the prevalence of alcohol consumption among Bugat soum population of Bulgan province.
Materials and Methods
The cross-sectional survey used a questionnaire of the WHO STEPS survey and adapted it to the local specifics. Alcohol consumption was assessed using the concept of “standard drinks”. A total of 201 randomly selected 15-64 year old residents of both sexes of Bugat soum were involved in the survey. The survey data was collected in September, 2011. The survey data was fully collected using small handled computers (PDAs).
Results
The survey respondents, 30.3% consisting of males (16.9%) and females (41.2%) were past 12 months abstainers. Of the alcohol users, 69.7% (males 83.1% and females 58.8%) reported drinking during the past 12 months and 47.3% were current drinkers or reported alcohol use during the past 30 days. In contrary, 60.9% of males and 36.8% of females were current drinkers or reported alcohol use during the past 30 days. In terms of the frequency of alcohol use by respondents reporting drinking in the past 12 months, 39.3% drank occasionally, 21.4% drank alcohol for 1-3 days a month, 2.5% drank 1-4 days a week, 4.5% drank 5-6 days a week, and 2.0% reported daily consumption of alcohol.
Conclusions
The survey results showed that current drinking or consumption of alcohol in the past 30 days was reported by 47.3% in herdsmen of Bugat soum. Of these 60.9% are men and 36.8% are women. As for the quantity of consumption, the current drinkers consumed 13.3 standard drinks for men and 5.0 for women. Frequency of alcohol drinking was higher in males compared to females. The prevalence of binge drinking was 2.5% in men and 0.4% in women, and binge drinking was 6 times more common in males compared to females.

WHO informed that across world an average of 565 young eople aged 10 to 29 die every day through interpersonal violence. Some studies mentioned that anxiety was most frequently occurred as one of the psychological onsequences among victims of child abuse. Recent research on effects of adverse early life experiences on central nervous system as stress systems (hypothalamus-pituitary-adrenal axis-HPA) has provided a greater understanding of the link between childhood abuse and susceptibility to anxiety disorder. Therefore, this research was done to study nxiety among abused adolescents, some physical parameters and level of cortisol in saliva.Total number of participants were 149 children aged between 11-16 years (number cases were 53, matched control subjects were 96). The Spence Children’s Anxiety Scale (SCAS; Spence, 1997) is a 38-item self-report uestionnaire that assesses multiple symptoms of childhood anxiety disorders based on current diagnostic criteria. All participants were measured the cortisol in the saliva by Cortisol ELISA kit, Sigma, USA. Average age of all subjects in the study was 13.52±1.57 and 102 of all subjects were female and 47 were male. All anxiety symptoms of case group was statistically significance higher (p<0.01) than control group. The average amount of salivary cortisol of case group was (21.3±8.1 ng/ml) statistically significantly lower (p<0.01) than average amount of control group (31.56±16.9 ng/ml). Anxiety was more frequently occurred among abused children and blunted cortisol responses might indicate a level of impaired HPA functioning that could constitute a vulnerability to psychopathology with exposure to anxiety.

To detect factors influencing infant’s weight growth during the last few years and to do comparing analysis between mother’s and infant’s weight. 3600 birth histories were chosen and used out of all childbirths happened in 2010-2014 in Ulaanbaatar’s First Maternity hospital using random sampling method. Questionnaires consisting of 21 questions were performed within primiparas, mothers giving birth not for the first time and mothers giving birth by cesarean section. Processing of all the workings were done by using Microsoft Word 8 and Microsoft Excel 2007.According to the results of the research there is a tendency to weight growth of the infants. Comparing weights of the first child of the woman (women giving birth repeatedly and women giving birth by cesarean section) with the second one there is an increasing number of infants with heavier weight. And also as per research done within primiparas there is an increasing number of children born weighting more than 4010 grams during last 5 years. To compare heights of the women giving birth, there is a dominating number of women whose heights are between 155-160,9. However, there is a tendency of birth rate to increase in women whose heights are 161cm. According to the research 63% of all women giving birth were 21-30 years old, average age of women is 28,1 years old. We also detected that there is a dominating number of women giving birth for the 2nd time, but also we concluded that there is an increase in a frequency of women giving birth for the 3rd and 4th times as well. Birth frequency\5 years average\: according to the research we have done we are concluding that 46% of all women are giving birth for the 2nd time, 48%- for the 3rd time, 5% of all women are giving birth for the 4th time and 1% of them are having their 5th child. Significants of cesarean section: 338 are repeated cesarean section, 228 are chronic hypoxia, 131are preeclampsia, beech presentation are171 and other. Childbearing time comparing there is an increase in childbearing of 40-41 weeks.. Comparison between first child’s weight and second child’s weight. As per comparison done between a women’s previous child’s weight and a present child’s weights there is a decrease in a number births of children weights of whose are between 3000-3500 g of 8%, and also an increase in number of births of the children weighting 3510-4000 g by 9,2%, of the children weighting 4010-4500 g by 3% and of the children weighting more than 4510 g by 1,4% was seen. Compare between weights of the first child and second child of the women giving birth by cesarean section done between first and second children’s weights we detected that there is an increase in a number of children weighting 3000-3500 g by 10,4%, weighting 3510-4000 g by 10,2%, weighting 4010-4500 by 12,8% and weighting more than 4510 by 2,59%. Women’s first child’s weight comparison are showing there is a dominating number of children born weighting 3000-4000 grams, however, we also see that there is a slightly increase in number of children born weighting more than 4010 grams. As per research we have done between average heights of the women giving birth in a last 5 years we are concluding following: height of 13% of all women who were involved in a research was 149-154 cm, 39%’s height was 155-160,9 cm, 27%- 161- 166,9 cm and 19% of them were taller than 167cm. According to the research we see dominating number of over weighted women. Despite of sampling method not showing good enough picture of weight index increase we can conclude that number of 2r and 3r levels of overweight mothers are not only staying at the same level but also has some tendency to grow. It was observed that the fact of weight gaining, bad eating habits, not doing sports during pregnancy and increasing of women height acceleration and post-term pregnancy are influencing infant’s weight gain which leads to infant’s morbidity and pathology and to complications during pregnancy and childbirth.When women give birth repeatedly with every birth they give there is an increase in a child’s weight. And also between primiparas there is an increased number of children born weighting more than 4010 grams.Between women involved in a research there is a dominating number of women who are 155-160,9 cm tall, however, it is 46% of them whose heights are more than 161 cm. It shows that average height of Mongolian women is increasing.According to weight index not only women with overweight are dominating, but also number of women with 2 and 3r levels of overweight never goes down and slightly increases. From this we may conclude that overweight problems of women are influencing weight of the baby and also contributes to childbirth and pregnancy complications.

In United States, person is diagnosed with blood cancer in every 3 minutes. In 2015, there were 1.665.540 total cancer cases and 9.4% of them lymphoma and leukemia . In 2015, there were 95 cases of lymphoma in Mongolia when compared 4 times increase to 2015 from 2010 . Bone marrow examination is an established diagnostic modality in the evaluation of various hematological disorders. BM examination can serve to establish or confirm a primary diagnosis of lymphoma or to determine the extent of disease dissemination for staging purposes. Biopsy is essential for diagnosis in a dry tap or blood tap which occurs when the marrow is fibrotic or densely cellular. Only a biopsy allows a complete assessment of marrow architecture and pattern of distribution of any abnormal infiltrates. In 2015.01-2016.01 fifty five bone marrow biopsies were retrieved from the files of the National First Clinical Hospital-Department of Hematology. These all statistical analysis was performed using by SPSS 17. Bone marrow processing and staining: The hematologist is instructed to place the freshly obtained BMTB specimens directly into buffer substance fixative and transport it immediately to the histopathology department, on the same day as the procedure.The next morning (after 20–24 h), the solution is decanted (with a strainer) and the biopsy specimen is washed in distilled water for 30 min. The biopsy specimens are left to decalcify for about 6 h before being processed and embedded in paraffin wax, with procedures similar as for other specimens.Sections, 1-mm thick (microtome set for 1 mm sections), are cut from the paraffin-wax blocks with the routine rotary microtomes in the laboratoryA total of 55 cases were reviewed from December 2014 to November 2015. The age of the subjects ranged from twenty two years to seventy eigth years with a male predominance (1.7:1). Data of 55 trephine biopsies were reviewed. The percentage of trephine biopsies in different length ranges was calculated. Twenty two biopsieswere of recommended length, i.e., ≥1.5 Cm while remaining 33 were less than the recommended length. The rate of positivity for diagnosis was 95.4% in group-1, 94.1% in group-2, 63.6% in group-3 and 40% in group-4 In all cases in our study 73% (n=40) were satisfactory and 27%(n=15) unsatisfactory slides .Our study showed that 40% trephan biopsies were of revommended length i.e >=1.5cm with 95.4% positive of diagnosis. However biopsies measuring 1-1.4 cm also had comparable result 94.1% .

GoalTo evaluate the quality, results, and processing of cytology analyses of early detection program ofuterine cervical cancer implemented in Mongolia, which based on Pap test, at Ulaanbaatar city level.Materials and MethodsInformation was collected from the databases of the recalling system of screening program of theCancer registration and information unit of the NCC of Mongolia and districts pathology laboratoreis.Statistical significant level of 1.96 (95% CI) andthe margins of error 0.05 were considered andsample size was calculated by using the information that 10% of unsatisfied results appear onquality assurance of international level. Thus calculations were madefortotal of 1723 (585 positiveand negative 1138) samples, by collecting 287smears from each district.At the district level all the selected slides were reviewed blindly and compared to the previouscytological conclusion. Diagnostic validity was defined by calculating parameters such as specificityand sensitivity, positive and negative predicted values. The Kappa index criteriais used for statisticalcalculation of the cytological diagnosis conclusion matches.ResultsThe target group women coverage of cervical cancer screening program is 40.8%. Out of all positiveresults of early screening cytology, 77% were at an early stage and 23% were at an advanced stage.Thus positive signs were showed with increased detection results in early stage of uterine cervicalcancer (P = 0.05). Positive results of Pap test were follows; ASCUS (53.2%), ASC-H (10.0%), LSIL(19.2%), HSIL (13.4%), CIS (3.4%), and SCC (0, 8%). Out of total slides, 86.7% were as satisfactory.The test results conducted at the district level were90.1% of sensitivity, 88.8% of specificity and9.9% of false negative response. The discrepancy of results of cytology test in districts and repeatedseen is 31.4% (K = 0.749; p = 0.001).ConclusionThe coverage of cervical cancer screening program that has been implementing in our country isnot enough. There are problems at the district level including severe damages of uterine cervix andincomplete diagnosis. The quality of the cytology test is relatively unsatisfied.

Among world population, 23.4% have different kinds of hearing disorders and 56% are middle ear disorders, 30% are inner ear disorder, 10% are congenital deaf and 4% are congenital mixed outer and middle ear disorder (WHO info, 2006).In 1995, by the German research, 2% of newborn babies were deaf therefore, among children from 1-18, 16% had middle ear disorder and 0.8% had inner ear disorder. In most cases (54%) cause of hear loss and deaf as sound transmitting apparatus. Later in 2010, sound transmitting apparatus related disorder was decreased by 22.4% J.Helms1995 , K.Schwager 2010 . Doctors proved that 62% of sound transmitting apparatus related disorders are middle ear diseases, 16,2% out of the diseases have the defect of malleus, 44,1 % have the defect of incus and discontinuity of incus and stapedius, and 39,7% is totally absent of ossicular chain 120 tympanoplasty III type surgeries were operated in 2011-2013 in Mongolia. Clinical and operative features of the tympanoplasty III type surgeries were prospectively recorded. Aim: To recover sound transmitting related hear loss with titan prosthesis implant. 120 tympanoplasty III type surgeries were operated in 2011-2013 in Mongolia. Clinical and operative features of the tympanoplasty III type surgeries were prospectively recorded. Out of the surgeries, 51 cases (42.5%) were cholesteatoma, 53 cases (44.2%) were granuloma middle ear and 16 cases (13.3%) were adhesive otitis media. The air and bone gap of all patients were above 15-35 dB. HEINZKURZ firm’s TTP-Variac system’s titan prosthesis was used. Titan prosthesis PORP was carried out in 86 cases (71.6%). For 40 (45.5%) out of the 86 cases, size of titan prosthesis PORP 2.25 mm was chosen. Hearing level increased for 72% out of patients by 10-25 dB after the operation. However, for 46 (54.5%) out of the 86 cases, size of titan prosthesis PORP 2.5 mm was chosen. Hearing level increased for 82% out of patients by 10-30 dB after the operation. Titan prosthesis TORP size 4-4.25 mm waschosen for 34 (28.4%) out of 120 cases. Hearing level increased by 10-30 dB for 80% out of patients involved after the operation Out of the surgeries, 51 cases (42.5%) were cholesteatoma, 53 cases (44.2%) were granuloma middleear and 16 cases (13.3%) were adhesive otitis media.Titan prosthesis PORP was carried out in 86 cases (71.6%).

BackgroundHuman-induced climate change will affect the lives of most populations in the next decade and beyond. The impact of meteorological conditions on human health has been reported globally. There is a need to conduct surveys for correlation between climate change and human health.GoalTo study the impact of air temperature on human health in selected aimags and city districts.Materials and MethodsIn order to study how climate change and air quality parameters affect human health we selected Zavhan, Selenge, Dornod, and Umnugobi aimags which represent different climate zones and 2 districts of Ulaanbaatar city during 2009-2011. All data for respiratory system disease J00-J99, circulatory system disease I00-I99, were collected from soum, district’s hospital, and aimag and soum’s Department of health.ResultsDuring the study period, a total number of 8649 incidences of respiratory disease are registered. From them 74.2 percent are influenza and pneumonia (J09-J18), 17.6 percent are other acute lower respiratory infections (J20- J22), and 8.2 percent are asthma (J45-J45.9). For cardiovascular disease 15288 incidences are registered. From them 65.6 percent are hypertensive disease (I10-I15), 23.6 percent are ischemic heart disease, and 10.8 percent are cerebrovascular diseases (I60-I69). The lower the air temperature, higher the incidence of influenza and pneumonia, acute lower respiratory infections, hypertensive, and ischemic heart disease.ConclusionsCold weather is correlated with a higher incidence of respiratory and cardiovascular diseases.

BackgroundClimate change, as defined by the United Nations Convention on Climate Change, is a “Change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and is observed over time”. In 2001 an Initial Communication on Climate Change was prepared by the Government as part of its obligations under the UNFCCC. One of its recommendations was for “creating public awareness among a wide range of stakeholders including public, private and community sector organizations”. GoalThe main goal of the study was to develop recommendations and measures on prevention from diseases and adaptation to climate change by assessing knowledge, attitude and practice (KAP) of population towards climate change. Based on the main goal the following objectives were setup. Therefore addressing the different levels of knowledge and types of attitudes and practices people have towards climate change must initially be dealt with at the local level where site specific variations can be accounted for. Once research has been undertaken at the local level it can later inform decisions and policy at the regional, continental and global levels on how to incorporate site specific variations with in the greater context of the global threat.Objectives:1. To determine knowledge and attitude of population towards climate change;2. To determine practice of population on some adverse consequences of climate change;3. To develop recommendations and measures on prevention from and adaptation to climate change;Materials and MethodsThe study was at once carried out by means of questionnaire. In order to assess KAP of population, the data was collected using a card with 38 questions in three chapters which previously produced and ratified. The questionnaire was structured into 4 sections; demographics, knowledge, attitudes and practices. Two sums in an aimag from each climate zone of Mongolia were selected. In total, 2258 respondents aged 15 to 64 were involved from eight sums in four aimags (Zavkhan, Selenge, Dornod and Umnugovi), and two districts in Ulaanbaatar. The study data was input to computer using EPIDATA-3.6 software and statistically analyzed using SPSS-18.0 software.ResultsA total of 2258 individuals were interviewed. 44.1% 44.1% (995) of the participants was residents of Ulaanbaatar city and remained percentages accounted for residents living in the center of aimags and soums. 56.7% (1281) of participants were women and 43.3% (977) were men aged with 35.2±15.1 in average. Most of the study participants had educated with medium level (34.8%) and high level (30.0%). Employment percentage is 47.5% (1073). However, most respondents interpreted the meaning of climate change as “a change in weather,” “a change in normal climate conditions,” or “a change in temperature” – answers that requires more common sense than climate change savvy. Global warming is one of the evident of climate change. To know study participants awareness about climate change we used terminology of global warming. 25.3% (571) of the total participants answered that climate change revealed by the overheating or warming earth surface. 42.4% of the respondents answered the climate change could affect to health, 33.2% to environment and 16.3% to economy. 84.5% (1908) of the study participants agreed with that climate change has been started. Most of them (71.3%, 1824) allowed that people’s improper use of nature tend to global warming. When ranging the protection practices during the strong storm means of timbering the houses or gers accounted for 42.5% (960). Study participants supported the following activities; 41.2% (931) agreed that is it necessary to increase health services and 34.1% (769) suggested that it is better to enhance training and propagation for increasing awareness of population about climate change adaptation procedures and some information on climate changes and protection events. 85.2% (1923) of the study participants answered that they want to get the information on climate change from public TV.ConclusionsAlthough knowledge on global warming as the climate change was poor among the respondents, they agreed the climate change has already been started worldwide as well as in Mongolia. Only half of the respondents have had practice to prevent themselves from natural disaster.

Otosclerosis is a disease that involves the cochlea and it is developed when the structure ofconnecting tissue in the area of stapedius and the oval window has changed and become unmovable.Consequently, conductive hearing loss and therefore severe sensorineural hearing loss are caused.The causes of otosclerosis have not been discovered yet but many factors impact on this disease. Anyresearch works has not been done on otosclerosis in Mongolia until now and we have conducted theresearch in 2008-2013. Therefore, we aimed to identify the hearing condition after surgery treatmentof otosclerosis.41 patients /47 ears/ who were diagnosed of having otosclerosis with conductive hearing loss, nomiddle ear infection through the comprehensive ear and hearing examinations were selected in thisstudy which was done at EMJJ Clinics between 2007 and 2013. The hearing improvement after thesurgery has been tested under bone and air conduction frequency 500, 1000, 2000, 4000, 8000 Hzand the results before and after the surgery were statistically processed on Excel 2010 and SPSS 17.0software programs. Stapedotomia and Stapedoectomia surgery approaches were applied and afteropening of attics, the hearing bones are palpated and the diagnosis of stapes otosclerosis is confirmedby the surgeon, who removes the stapes. Then a titanium K-piston (prosthese or implant) is thenplaced into this opening and connected to the malleus, or the incus.Out of 41 patients (85.4% female) involved in the study and 36 people had one ear side otosclerosisand 5 people had both ear otosclerosis. After the surgery 25 patients did not have dizziness andvomiting symptoms and 14 patients did not have dizziness with movement after 12 hours, andfor 4 patients all symptoms were disappeared after 24 hours. As for the result from the hearingexamination after 21, 60 days of the surgery, bone conduction was normal, air conduction, andhearing for 32 patients improved completely, and after 120 days of the surgery, the hearing of 33patients improved completely, bone conduction became 2000 Hz at 4000 Hz frequency 12-15 dB,average of air conduction 15,4±10,1 dB, bone-air gap 10,4±3,1 dB for 5 people, and bone conduction2000 Hz-4000 Hz, at 8000 Hz frequency 20-40dB, air conduction became 25-45dB 10,4±5,1db for 9patients and all patients had no hearing loss except for 4 people who still had tinnitus.After surgery stapedotomia and stapedoectomia for the otosclerosis, the hearing improvement was95.2% and it has been concluded that there is full possibility to perform surgeries of stapedotomia andstapedoectomia for the otosclerosis in Mongolian situation.
