BACKGROUND. Otitis media (OM) is any inflammation of the middle ear. It is very common in children. The purpose of Survey is to analyzing result that insertion of tympanostopmy tube treatment for children who had otitis media. METHOD. The study covers total 482 tympanostomy surgery cases conducted, between 2013-2015, at ENT Surgery Department, National Center for Child and Maternal Health. Titanium tube had been placed for the patients with either adhesive otitis media and otitis media with effusion. In order to evaluate surgery results, follow up examinations were carried out in 2 weeks, 1, 3 and 6 months using otoscopy, audiometer, ABR and ASSR test. RESULTS. Most of the children (82.4%) in whom a ventilating tube have been placed in tympanic membrane had exudative otitis and the remaining (17.6%) children had adhesive otitis. In means of age group, children with 0-2 years, 3-4 years, 5-6 years, 7 and more were, 39.9% (n=173), 42.7% (n=206), 15.6% (n=75) and 5.8% (n=28) respectively. After the tympanostomy surgery tympanic membrane color gets better, turns pearl grey, fluctuation improves, membrane cavity pressure lowers to -50daPa and hearing status ranged 20.4-5.4dB which allows the patient to continue normal speech development. CONCLUSION. Among 482 patients whom involved surgical procedure of Insertion of tympanostomy tube treatment last 3 years in Department of Pediatric Otolaryngologists in Maternal and Child Health of Mongolia and otitis media with effusion and adhesive otitis media type were occurred 30% to 40% from above cases. After tube placement tympanic membrane movement improved and color of tympanic membrane is getting pearl-grey and middle ear pressure decreasing until to 50daPa and children hearing range changed 20.4 to 5.4 db. So we could prevent these children suffer speech disorder .

Introduction. There is group of mental disorder characterized by several physical symptoms are not fully explained by general medical condition, individuals visit many doctors and undergo numerous physical examinations, diagnostic tests associated with their suffer but no physical cause can be found. A third somatoform pattern is somatization disorder, characterized by numerous and recurrent physical complaints that begin by age 30. The prevalence of this disorder is 1-2% among adult population and it is occurred more female than male. Goal. To study some clinical symptoms among people with somatization disorder. Materials and Methods. This study was conducted with quality research method semi-structure questionnaire among the 30 people, who admitted to state and private hospital and sanatorium in the Chingeltei, Songinokhairkhan, Khan-Uul, Sukhbaatar, Bayanzurkh and Bayangol district in Ulaanbaatar city province for medical care. We did random sampling for unexplained somatic symptom individuals by diagnostic criteria as followings: 1.Multiple, recurrent, clinically significant somatic complaints no physical cause can be found over the last 2 years. 2. There must be a history of a visit at least 3 times for professional medical help due to their constant suffer. 3. Did not accept their medical diagnose and conclusion, even though no evidence of somatic symptoms. Results. There were 20 female and 5 male patients in our study, aged 23-78 years old were involved into our interview, and the average age was 44±0.8. We were clarifying clinical symptoms, such as gastrointestinal, cardiovascular, sexual function and urinary tract for all participants. The most of participants occurred gastrointestinal symptoms, such as nausea, vomit and timpanists. Also, all of the participants experienced heart beat symptom. As four of the 5 males reported loss of libido and majority of the females occurred pollakuria and sensopathy symptoms.Conclusion. Gastrointestinal symptoms (nausea, vomit and timpanists), cardiovascular symptom (heart beat), sexual function and urinary tract (loss of libido and pollakuria) and sensor conversion (sensopathy) occur mostly for somatization disorder.

Rotenone is a specific inhibitor of the NADH dehydrogenase complex. In mitochondria, rotenone inhibitsthe oxidation of NADH to NAD, thereby blocking the oxidation of NAD and the substrates such asglutamate, alpha-ketoglutarate, and pyruvate. Rotenone also inhibits the mitochondrial respiratory chainbetween diphosphopyridine nucleotide and flavine.2, 4-Dinitrophenol – (DNP) is lipophilic weak acids that pick up a proton, transport across the mitochondrialinner membrane into the matrix, deprotonate, then exit as anions before repeating the catalytic cycle,and dissipating the proton gradient. In this situation, electrons continue to pass through the electrontransport system, reduce oxygen to water and metabolic rate, heat are increased, but ATP is lesssynthesized in this process.The macrolide antibiotic - oligomycin binds to the surface of the c8-10 ring of the Fo domain of ATPsynthase, making contact with two neighboring molecules and blocking proton flow, which explains theinhibitory effect on ATP synthesis. Intraperitoneal injection of oligomycin into the rat (0.5 mg per kg)reduces the oxygen consumption by about 50%; decreases ATP production by the aerobic pathway andincreases formation of lactate in blood serum. These changes may cause a decelerated metabolism andan increased formation of free radicals or ROS in membranes.

The oral hygiene is not relatively good cause of smoking, ignoring oral hygiene, not having enough self-care skills and independent living in case mental illness. Their grinding the teeth, serotonin decreases when the people are depressed and then it makes the carbohydrates increases, loses the sense of taste. Therefore they use a lot of sweet, the salivary output decreases, increase in the number of lactobacili and then it makes the cause ofabnormal disease detections including tooth decay, trigeminus neural pain in temporomandibular joint /TMJ/, oral yeast infection, oral bad breath, burning sensation of the tongue, chronic facial pain. Also the oral can disease detects from drug causes like using the anti-depression drugs for at least 6 months.Using analytical research permanent design, I got 55 patients to take part in the survey who are staying in 5th flat , National Clinic of Mental Health from 22nd of September 2014 until 26th of September. When I do the research for history of their patients: among the diagnosis of 16 people disorder depressed, the 13 patients agreed to have a preventive examination voluntary, one of them declined to do it. I use many methods of researching like questionnaire methods interview method, prevention oforal cavity and clinical examinations, respectively Study shows that curriculum contents of School of Nursing, Mongolian National University of Medical Sciences have comparatively less contents of understanding about healthy person, assessment on human, giving advice healthy human, path anatomy, physiology, communication skills.The most of the survey participant patients have holes in their teeth, gum inflammation, and tongue stress disorder. It shows that it decreased to pay attention on their oral hygiene associated with symptoms and it effects directly related to the decrease in salivary output.Depressed People are so bad at paying attention to their oral hygiene habits.

BACKGROUND. Hearing loss is likely to be the most common congenital abnormality in newborns, with a reported prevalence of 1 to 2 per 1000 live births. It is vitally important to diagnose infant hearing loss or deafness at its early stages. Early detection and intervention is critical to prevent the adverse consequences of a delayed diagnosis on speech, language and cognitive development. Universal screening of hearing loss has been introduced in practice with distortion product of otoacoustic emission (DPOAE). The automated auditory brainstem response (AABR) screener is a dedicated hearing screening device which provides information not only about the outer and middle ear and cochlea but also about the auditory pathway up to the brainstem. METHODS. The study was descriptive and based on a retrospective analysis of the two year period databases (2014-2016) from the newborn hearing screening program. We have started the hearing screening from December 2012. Between 2014 to 2017 we have been screened total of 11218 newborns. We tested automated audiotory brainstem response of the newborns in their 1- 3 days of birth, using Maico MB11 Beraphone machine (German) according to the Joint Committee on Hearing Screening guidence. We assessed the test result of “pass” as “normal hearing, “refer” as to rescreen and tested again after 1 month. Infants referred again were gone to a specialist for further audio logic analysis (behavioral tests, auditory brainstem response, otoacoustic emissions and auditory steady state response). RESULTS. Our study was the first in Mongolia. Total of 10290 newborns passed bilaterally out of 11218 and 1323 referred in the first screening. For the rescreen test, 1088 out of 1134 infants resulted with “pass” and 46 infants with “refer”. For those infants, we did ABR test in their 3 and 6 months, and result of 9 children (18 ears) have bilateral profound hearing loss, 2 children (2 ears) have bilateral mixed profound hearing loss and 13 (26 ears) have bilateral profound conductive hearing loss. Coverage rate was 34,7%. First refer rate was 11,7%. Follow rate was 39,7%. We conducted the cochlear implantation surgery for 2 children out of 11. Currently, we are preparing other infants with bilateral profound hearing loss of 0-3 years old for the follow up CI surgery. CONCLUSION. In Mongolia, the data of infant hearing difficulties and prevalence of deafness is lacking. Although newborn hearing screening program has been approved in 2014 and brought opportunities to conduct universal neonatal hearing screening program. But at the moment, its only available at NCMCH which located in Ulaanbaatar city. 11 cases have a bilateral profound hearing loss out of 11218 newborns. Our study result shows similiar pattern (1.1 - 1.3 ear deafness in every 1000 birth. Lenarz et all.2008). Automated audiotory brainstem response was efficient in early identification of newborn hearing loss with high sensitivity and specification rates. Small population in the remote locations, high birth percentage, short period in the hospital after birth, lack of technology and human resources, and other factors result in higher level of referral rate newborn hearing screening and lower level of follow up and confirmation rate referals in Mongolia.

Background. Low back pain is a frequently encountered symptom. Although 70-80% of the entirepopulation have low back pain complaints in their lives, only 2-4% of them require surgical intervention.’Department of Neurosurgery, Shastin 3rd Central Hospital about 200 patients who undergo back surgery,while 90% of patients who have prolapsed lumbar disc surgery from 2010 to 2012. There are variousstudies indicating that exercise improves pain and disability in chronic low back pain and in those whohave had surgery. The main objectives of the postoperative rehabilitation programmes are to accelerateand maximize function recovery as much as possible, and to prevent further injury by restricting theprogression of degenerative changes. We evaluated the effectiveness of rehabilitation treatments thatare used in our department which is the first time in our country.Goal. To evaluate the effectiveness of rehabilitation after lumbar discectomy.Materials and Method. We examined 83 patients were included the Shastin central hospital, Departmentof neurosurgery and rehabilitation after lumbar discectomy at a single level and operated in the periodfrom May 15, 2013 to September 15, 2014. All patients were evaluated at the beginning and at theend of treatment by Oswestry Disability Index which is a specific functional questionnaire for back pain.Pretreatment values are one month after surgery and posttreatment values three months after surgery.All patients received the intensity specific exercise and back school education programme 3 days aweek for eight weeks.Results. All patients pain intensity are reduced after treatment evaluated by VAS (p<0.000). Functionalability had significantly increased after treatment which is evaluated by Oswestry Disability Index in allpatients (p<0.000). 46 from all patients had minimal disability before treatment and this number wasincreased in to 79 after treatment. The number of moderate and severe disabled patients ability wasincreased after treatment.Conclusion: Back school education and specific exercise programme should be one of the parts oftreatment after lumbar discectomy. After treatment was increased functional ability and early painrelief.

BACKGROUND. Sensorineural hearing impairment (SNHI) is the most common inherited sensory defect, affecting about 3 per 1000 children. More than 50% of these patients have a genetic cause (i.e. hereditary hearing impairment; HHI). Mutations in certain genes were noted to be extraordinarily popular in the deaf patients across different populations, making molecular screening feasible for these common deafness genes. One of the most important characteristics that we have learned concerning hereditary hearing loss is that common deafness genes and their mutations are usually different according to the ethnic background. As demonstrated in our previous studies performed in Taiwanese patients, the mutation spectrums of common deafness genes, such as the GJB2 gene and the SLC26A4 gene, are different from those in the Caucasian or even other Asian populations. These findings further underscore the indispensability of the collection of local data in terms of genetic counseling. In the collaborative project, we have successfully established a cohort of >100 hearing-impaired families, and clarified the genetic epidemiology of deafness in the Mongolian population. We identified several special deafness mutations such as GJB2 c.23+1G>A, c.559_604dup, and SLC26A4 c.919-2A>G, and our results revealed that Mongolian patients demonstrate a unique genetic profile in deafness as compared to other East Asian populations (paper in preparation). Meanwhile, by organizing a seminar at National Taiwan University Hospital in March 2017, we have transferred crucial concepts and techniques regarding how to perform genetic testing for deafness to the Mongolian colleagues. In the future, we plan to strengthen the mutual collaboration by expanding the clinical cohort and upgrading the genetic examination platform using the NGS techniques.

Background: Some findings of an artifacts have revealed that nature based the raw have been used for the treatment of mankind's diseases over 60 000 years ago. WHO estimates that about 80 percentage of the world's population are consume the traditional medical care, and uses more than 21,000 plant species for therapeutic purposes. In order to help guide its member countries the World Health Organization (WHO) has developed The WHO Traditional Medicine Strategy 2014-2023. Some of the strategic actions in this document include:
• To develop and share appropriate research methodologies and criteria for evaluating the safety, efficacy, and quality of TM (Traditional Medicine) products;
• To study and explain the disease prevention, health maintenance, the diagnosis and the treatment of the TM disease according to the evidence based scientific studies. Objectives: to determine the most frequently used medicinal plants for the treatment of "Rlung" in the TM. Methods: The comparison method, the synthesis and analysis method, the induction and deduction method, the listing and sorting method, the inspecting and arrange method, and the methods of documents' drafting were used in this study. Results: It is shown that over 80 raw materials of plant, mineral and animal origins has to list within 32 drug recipes which used "Rlung" disease of TM. The first five raw materials from these 80 ingredients have been repeatedly lists zadi - 30, agar (black, white, red agar) -19, arur-19, lish -18, and nin shosh -18 times. Conclusion The most frequently used the raw materialin the treatment of "Rlung" diseases is the seeds of Myristica fragrans Houtt. which contains a lot of the saturated acids with membrane-enhancing effects and strong antioxidant substances.

Background: Headache disorders are most prevalent public-health problem. Worldwide, among the adults 46% suffer from primary headache, where the migraine presents 11% and tension type headache (TTH) presents 25%. Recently, one type of the primary headache, medication overuse headache tends to increase. Nowadays, there is no sufficient study about primary headache in Mongolia. So that, it is necessary to investigate prevalence, clinical type and risk factors of the primary headache. Purpose: To study prevalence and risk factors of primary headache in Mongolia. Materials and Methods: This cross-sectional study was carried out from June to November of 2017. Participants aged 18-65 years old were randomly selected from four provinces and three districts of Ulaanbaatar city. The diagnosis of headache was made using the International Classification of Headache Disorders-3 beta. Statistical analysis was performed on SPSS-23 program. Results: A total of 2043 participants (812 men and 1231 women) were reviewed. The participant’s average age was 38.6±13.4years. 1350 (66.1%) participants reported recurrent headache within the last 1 year. Of the total study population, the prevalence rate of primary headache was 1305 (63.9%). Number of people who suffered from migraine was 494 (24.2%), significantly greater in female than male participants (p=0.0001), with most frequent attacks at age 26-45 years. The risk of migraine associated with sex, education and family history (p=0.001). 592 (29.0%) of participants had TTH, mean age of them was 37.7±5.24, significant high rate in female than men, risk of TTH depends on education and job. The medication overuse headache was diagnosed at 116 (5.7%), 29.4% in men and 70.5% in women with average of 45.6±11.4 and 43±12.7 respectively. Among the participants 38.6% used medications, 28% people had one drug, 8.5% two drugs and 2% used three or more drugs. Use of non-steroid anti-inflammatory drugs (NSAID) made up major percent in headache patients. Increased frequency of medication and multidrug affected to medication overuse headache (p=0.008). Conclusion More than half of studied population had primary headache. Migraine was in 24.2%, TTH in 29.0% of people, and associated with sex, education and family history. Use of non-steroid anti-inflammatory drugs made up major percent in headache patients.
