Congenital heart disease is the most common group of congenital disorder with a reported prevalence that rates from 8/1000 live births. Also, CHD accounts for nearly one-third of all major congenital anomalies. In recent years, the country’s congenital heart disorders diagnosis has improved significantly, but has been of late diagnosis of cases.Once the diagnosis of congenital heart disorders later case, the resultant complications occurred because the majority is unable to similarly cardiac surgical treatment. Therefore, early diagnosis of congenital heart defects, and thus treatment is necessary to solve the problem early.A retrospective, descriptive study was conducted from January 1st8 2012 and January 1st8 2013 there were 263 deliveries at the Urgoo maternal hospital and child health research center of Mongolia. We reviewed the medical records of all neonatal in 2012-2013 who were born in the Urgoo maternity hospital of Ulaanbaatar and NICU and NCU of National Center of Maternal and Child Health. A total of 263 infants with congenital heart disease.The number of neonatal intensive care unit and neonatal unit with Congenital heart defect was 99 (37.7%) in 2012 were as there 164 (62.3%) in 2013 increasing 1.4 times respectively. A total of 263 infants met the inclusion criteria, of whom 130 (55.1%) were males. The reasons for the higher incidence of congenital heart defect observed in infants remain unclear.The most frequently occurring conditions were patent ductus arteriosus /21.7%/, arterial septal defect with patent foramen ovale /41.2%/, other majority defect-31.9%, Dextracaria-5,2%. This raises question regarding the clinical significance of some of lesions, such as small VSDs, which are widely considered to be congenital heart defects. When all clinical presentations of heart disease were analyzed together, atrial septal defect (ASD), Ventricular septal defect (VSD), and Patent ductus arteriosus (PDA) accounted for 62.9% of all defects identified. From diagnosed CHD with percent less than was critical congenital heart defect, which required urgent surgical treatment in neonate period.CHD is expected to increase in the coming years. Thus, when the fetus is affected by a malignant diagnosis.According to the survey findings to diagnose congenital heart defects in the first weeks of the prognosis and treatment options, and shows that it is important to prevent complications. Obstetric and regional diagnostic centers in rural pediatric cardiologist and ultrasound machines shows that it is important for diagnosis and treatment.

The Jones criteria is a clinical guideline for the diagnosis of rheumatic fever(RF) and carditis. The clinical features were divided into major and minor categories. Major manifestations include carditis, joint symptoms, subcutaneous nodules, erythema marginatum and chorea. The minor manifestations comprised clinical fi ndings(fever, artralgia, cardialgia,abdominal pain, nose bleeding ) and laboratory markers(Leukocytosis, elevated erythrocyte sedimentation rate and C-reactive protein, prolonged PR on ECG). It was proposed that the presence of two major, or one major and two minor manifestations offered reasonable clinical evidence of rheumatic activity.Carditis is the single most important prognostic factor in RF; only valvulitis leads to permanent damage and its presence determines the prophylactic strategy. The clinical diagnosis of carditis in an index attack of RF is based on the presence of signifi cant murmurs (suggestive of mitral and aortic regurgitation), pericardial rub, or unexplained cardiomegaly with congestive heart failure.Myocarditis(alone) in the absence of valvulitis is unlikely to be of rheumatic origin and by itself should not be used as a basis for such a diagnosis. Two dimentional echo-Doppler and colour fl ow Doppler echocardiography are most sensitive for detecting structural abnormality, abnormal blood fl ow and valvular regurgitation. This method can detect all audible valvular regurgitations to be dThe use of 2D echo-Doppler and colour fl ow Doppler echocardiography may prevent the overdaignosis of a functional murmur as a valvular heart disease. Similarly, the overinterpretation of physiological or trivial valvular regurgitation may result in misdiagnosis of iatrogenic valvular disease. Accurate interpretation of the echocardiographic signals is therefore important.

BACKGROUND:Our previous study has shown that the prevalence and structure of the neurohereditary diseaseswere different by provinces and some form of these diseases as “indigenous” in some isolatedpopulation. There are some scientific results of our researches–genetics about consanguineous,which is more potential factor of community is some area of Mongolia. All these circumstance isgiving to carry out this study.MATERIALS AND METHODS:We used descriptive epidemiological method for revealing hereditary neurological diseases in thepopulation of 6 provinces (aimags) of Mongolia: Dornogobi (Easth-gobi), Sukhbaatar, Gobisumber,Central aimag, Bulgan, and Darkhan-Uul. Total population of these provinces is 363072. Thenumber of population in 6 provinces was fluctuated in the range from 15.000 (Govisumber) to 88.875(Darkhan-Uul). Prevalence was accounted for 100.000 populations.RESULTS:The prevalence of neurohereditary diseases makes up 17.08 cases per 100.000 populations amongthese 6 provinces. 79% of these are hereditary neuromuscular diseases i.e 49 patients from 29families. Myotonic dystrophia and genetic neuropathies Charcot-Marie-Tooth have comparativehigh prevalence over test forms of disease.The high rate neurohereditary diseases was established in the population of Bulgan (35.80•10-5),Sukhbaatar (31.17•10-5), and Dornogobi (21.33•10-5) provinces. Their prevalence’s prevailed in the7-10 times over rates Darkhan-Uul, 3-5 times over rates of Gobisumber aimags.No neuromuscular forms of neurohereditary diseases i.e spastic paraplegia (11.3%) andspinocerebeller ataxia (9.68%) accounts for 21% among all forms of neurohereditary diseases.The prevalence of neuromuscular diseases in the population of these six provinces is two times highthen the average rate of the population of Russia (1980 years). First reason is may be associatedwith high predisposition of based on consanguineous through reproductive way in some of theseprovinces of Mongolia.

Congenital heart disease (CHD) is one of the most common birth defects, with an incidence of nine out of every 1,000 live births. Critical CHD (CCHD) is defined as cardiac lesions that require surgery or cardiac catheterization within the first month (or within the first year by different definitions) of life to prevent death or severe end-organ damage. An early diagnosis and timely intervention can significantly reduce the likelihood of an adverse outcome. However, studies from the United States and other developed countries have shown that as many as 30%–50% of infants with CCHD are discharged after birth without being identified. Pulse oximetry is a tool to measure oxygen saturation, and based on the presence of hypoxemia, many cardiac lesions are detected. Due to its ease of application to the patient, providing results in a timely manner and without the need for calibrating the sensor probe, pulse oximetry offers many advantages as a screening tool. Pulse oximetry was recommended as a screening tool to detect critical CHD in 2011 by the American Academy of Pediatrics and the American Heart Association. Pulse oxymetry screening (POS) for early detection of CCHD is a simple, noninvasive, and inexpensive test, which meets the necessary criteria for inclusion to universal newborn screening panel. Wider acceptance and adoption can significantly decrease morbidity and mortality in infants with CCHD.

BACKGROUND In Mongolia, Gastric cancer is second most common cancer. 904 (603-men, 301- women) new gastric cancer cases reported in 2016 and is about twice as common in men than women. The number of new gastric cancer cases was 29.3 per 100.000 men and women in Mongolia. A greater percentage of total gastric cancer cases were III, IV stage(85.5%). In 2016, The Orkhon province had the highest rate in Mongolia (54.3 cases per 100.000 men and women). In Mongolia and Orkhon province, gastric cancer remains an important public health problem. METHODS A total of 60 gastric cancer cases diagnosed at Medipas Hospital between March 2016 and October 2017 were analyzed retrospectively. RESULTS The average age of all gastric cancer patients was 59.75±9.91 years. The men to women ratio was 1:0.28. The most common location of gastric cancer was upper third(59.7%), followed by middle third (26.9%) and lower third (13.4%) of the stomach. Thepercentage of total gastric cancer cases were advanced gastric cancer (66.7%) than early gastric cancer (31.7%). And One case(1.6%) diagnosed MALT lymphoma. 55% of total gastric cancer cases were treated by Endoscopic submucosal dissection and Gastroectomy surgery. CONCLUSION One reason the overall survival rate is poor in the Mongolia is that most stomach cancers are diagnosed at an advanced rather than an early stage. The stage of the cancer has a major effect on a patient’s prognosis.

Background: Pneumonia is one of the leading causes of morbidity and mortality in children around the world. Annually, it’s estimated about total of 120 million cases of pneumonia occur in children under the age of five around the world and about 2 million of them end in mortality. In 2017, respiratory diseases constituted 31.3% of all diseases in children under the age of five in Ulaanbaatar city. 268 cases of respiratory diseases occur in every 1000 children, making it the leading disease in children of that age group. Sonographic examination has several advantages including lack of radiation, accessibility, portable (can easily bring it next to the patient’s bed), cost effective, and can be used repeatedly on the patients. To our knowledge, currently in Mongolia, there are no published research materials on sonographic examination in children with pneumonia. Given, the lack of study, increased rate of pneumonia and advantages of ultrasonographic, the present study was performed to detect lung ultrasound sign of pneumonia and determine the specificity and sensitivity of lung ultrasound and X-ray. Methods: The study used cross-sectional studies of analytical study. 379 inpatient children aged between 1 month to 14 years old who are in the children’s hospital of Bayangol district between 1st of September 2019 to 1st of December 2019 participated in the study. Procedures included collection of questionnaires from the parents or the guardians, random collection of data from the patients’ history, and assessment of results from ultrasound and X-ray examination. The study used Stata software to analyze the statistics. Results: 56% or 210 cases showed decreased echogenicity in the ultrasound examination. Incorporated B line sign (р=0.001),, decreased echogenicity in the consolidation (р=0.001), and presence air positive bronchus (р=0.001), are shown to the major sign of pneumonia in ultrasound examination. Conclusions In pneumonia, following signs are present in lung ultrasound: Unilateral B-lines, consolidation, hypoechoic, irregular shaped consolidation, positive air bronchogramm sign in lung. From the results of our research, we discovered diagnosis sensitivity of pneumonia in ultrasound is 85%, specificity of pneumonia in ultrasound is 87%, sensitivity of pneumonia in Х ray is 78%, specificity of pneumonia in Х ray is 84%.

BackgroundEarly detection of minor strokes and their treatment that aim to prevent from complications into severe strokes is a process of secondary prevention. There is a need to extensively use image diagnostics (CT, MRI) because signs are obscure, at times without focal neurological sign but can have special mental or psychological syndromes. The start of minor stroke studies in Mongolia will enable further deepening of these studies in future and give an impetus to identification of theoreticaland practical aspects together with further improvement of diagnostics, treatment and prevention of minor strokes.GoalTo develop and introduce the diagnostic criteria of ischemic and hemorrhagic minor strokes in accordance to the concepts of minor strokes and to treat minor stokes in order to prevent complications into severe strokes.Materials and MethodCurrently there are no globally accepted diagnostic criteria for minor stroke. We support the 1981 WHO criteria of minor strokes as strokes neurological signs of which disappear in relatively short period of time. There is a general notion that it should mean all light forms of stroke other than severe strokes. In cases of neurological signs of a minor stroke, complete recovery and elimination of the symptoms take up to 3 weeks. Most scholars tend to consider ischemic lacunar strokes (arising from occlusion of arteriole vessels deep in the brain and with size of 0.5-20 mm) as minor strokes. We maintained the concept that characteristic features of these strokes are their limited focal areas and the following neurological symptoms: pure motor, pure sensory, light ataxia, etc. We also duly considered a suggestion (D. German, L. G. Koshchug et al, 2008 ) to define minor hemorrhagic strokes as strokes with diameter less than 2 cm and blood volume less than 5 cm3.We identified 60 patients with minor strokes, involved in monitoring using special research template (with a term of at least 1.5years) and involved in pathogenesis treatment. In the treatment, we maintained a principle of differential diagnosis of ischemic stroke symptoms. Specifically, we differentiated the following: signs related to an atherotromb, cardio-embolic, lacunar, hemodynamic, hemorheologic pathogenesis. To verify the diagnoses, we used MRT and CT image tests. We executed paraclinic tests in order to identify risk factors: Doppler-duplex-sonography, brain angiography, blood lipid fraction, ECG, EchoCG, heart Holter, blood hemorheology test, and identified the most affecting factors (hereditary factors, excess weight, smoking etc).Results: Our study identified the following clinical forms: lacunar stroke, non-lacunar minor stroke, and hemorrhagic minor stroke. Among the minor strokes, the lacunar stroke dominates (48%), the nonlacunar stroke is the next (27.7%), and the hemorrhagic was found to be the least common 25%. From among a host of risk factors, arterial hypertension is dominant (86%) either alone or in combination with such other diseases as diabetes, atherosclerosis etc. Diabetes occurrence was 5 cases (8,3%) which is fewer than in some foreign studies.The clinic of minor stroke also varies. The strength and expression of their symptoms compared with those of severe strokes are unique in the following:- Relatively lighter and recover faster as a result of treatment even in acute forms,- Some are without specific clinical signs (“silent stroke”).- Some minor strokes have micro focal signs, for example, “pure motor”, pure sensory, ataxia etc, in other words, the signs are limited.- In cases of lacunar strokes, predominantly deep brain arterioles are damaged.- Whereas in non-lacun strokes, embolic, ateroma, thrombotic mechanisms are predominant suchas distal branches of big artery. - In cases of hemorrhagic minor strokes, arteriopathy distortions occur not only in depth of brain but also in any small lobar vessels of brain.- Focal lesions have some variations by their pathological locations and minor stroke signs.In non-lacunar strokes (25%), the focal damages predominantly occur in branches of large intra/extra cranial arteries. In cases of lacunars strokes, the focal lesion is not in branches of large intracranial vessels, but is predominantly in basal ganglia, deep white matter, thalamus, pons and in area of deep penetrating arterial vessels. However, focal infarcts in cerebella may occur in any form of minor strokes.ConclusionAccording our study there were identified 3 subtypes of minor stroke. The finding is that lacunars and hemorrhagic minor strokes are more likely to give grounds to severe strokes. From this, it can be concluded that there are specific factors in the population of Mongolia to affect the genesis of minor strokes, namely, arterial hypertension which is directly related with these forms of minor strokes. We appropriate the WHO criteria of minor stroke that is neurological signs of a minor stroke, complete recovery and elimination of the symptoms take up to 3 weeks. In treatment of minor stroke, we suggest that minor strokes should be treating by pathogenetic therapy. Namely, antihypertensive therapy for lacunar infarction, anti-aggregation therapy for nonlacunar infarction and haemostatic and antihypertensive therapy for hemorrhagic minor stroke.

Background: Congenital heart disease (CHD) is the most common congenital disorders in the newborn and about 25% of them are complex heart diseases which needs early intervention or open heart surgery in neonate period. The incidence of CHD is varies from 8-10 in 1000 live births and half of them are major heart diseases. Abnormal ductusvenosus blood flow at 110-136 weeks has also been described in association with fetal aneuploidy, cardiac defects and adverse perinatal outcome. In the last few years the clinicians are using the nuchal translucency, ductus-venosus regurgitation in fetus as a biomarker of congenital heart disease. Objective: To assess the method of combining fetal nuchal translucency and ductusvenosus blood flow measurements in the detection of major cardiac defects in the first-trimester scan. Methods: Prospective cohort study data was derived from first-trimester screening of pregnant women at National Center for Maternal and Child Health between March 2014 and May 2017.
A total of 318 patients at 110 to 136 weeks of gestation enrolled in the study. An ultrasonography scan was performed trans abdominally (using 3 to 7.5 MHz curvilinear transducers),first, to determine gestational age from the measurement of the fetal crown-rump length; second, to measure fetal nuchal translucency thickness; and third, to assess blood flow across in the ductus-venosus. Results: During the study period, we carried out an ultrasonographic examination at 110-136 weeks in 318 singleton pregnancies with a live fetus and crown-rump length of 45-84 mm. The median age of women was 34 (range, 19-46 years). In our study 9(2,8%) of all singleton pregnancies were diagnosed with major heart defects and increased NT, ductus-venosus regurgitation was shown to be strongly associated with the CHD. The sensitivity of nuchal translucency to CHD was 83% (p-0.0001), dustus-venosus regurgitation was 75% (p-0.007), ductus-venosus PI was 80% (p-0.001). Conclusions First trimester biomarkers for fetal CHD screening can detect major heart defects. Increased NT, abnormal DV flow can be important indicators for echocardiography, which is favorablefor early prenatal diagnosis of CHD.

Background: Stroke is a leading cause of death and disability, especially in low-income and middle-income countries and it impacts a tremendous medical, emotional and fiscal burden on society. Due to advances in Western healthcare, the prevalence of stroke since 1970 has decreased by 42%, whereas it has more than doubled in low-income to middle-income countries.
Stroke is a heterogeneous, multifactorial disease regulated by modifiable and nonmodifiable risk factors. Approximately 80% of stroke events could be prevented by making simple lifestyle modifications. In fact, nationwide characterization of well-known stroke factors in all social backgrounds is essential, however; populations can differ significantly not only in their socio-behavioral, legal, and geographical conditions, but also from other, historically understudied. Therefore, it is crucial to determine characterization of risk factors for ischemic stroke among Mongolian population. Objective: To determine etiology and risk factors for ischemic stroke among Mongolian population Material and methods: Our study was conducted by case-control study design. Cases were patients with acute first stroke; controls were matched with cases, recruited in a 1.2:1 ratio, for age and sex. The case series study was conducted in Stroke center of Third State Central hospital from January 2017 to December 2017. Structured questionnaires were administered and physical examinations were done in the same manner in cases and controls. Self-reported history of hypertension and diabetes mellitus or blood pressure of 140/90 mm Hg and blood sugar 6.4 mmol/L or higher was used to hypertension and diabetes mellitus, respectively. Smoking status was defined as never, former, or current smoker. Alcohol use was categorized into never or former, low intake, moderate intake, and high or episodic heavy intake. Atrial fibrillation was based on previous history, review of baseline electrocardiograph results (for cases and controls). Odds ratios (OR) and logistic regression were calculated, with 95% confidence intervals. Results: In total, 173 patients with ischemic stroke and 146 controls were included. The patients’ age ranged from 17 to 92, the mean age was 61.2. Ischemic stroke more frequent in man than women by 27.4%. Previous history of hypertension or blood pressure of 140/90 mm Hg or higher (OR 2.40, 95% CI 1.48-3.88), diabetes mellitus (OR 3.08, 95% CI 1.44-6.57), hyperlipidemia (OR 5.09, 95% CI 2.64-9.82) atrial fibrillation (OR 8.70, 95% CI 2.01-37.64 ), current smoking (OR 2.07, 95% CI 1.26-3.40), alcohol consumption (OR 4.75, 95% CI 2.58-8.73) were all significantly associated with ischemic stroke. The mean age was lower in patients with stroke of other determined etiology. The frequency of hypertension was higher in patients with lacunar infarct than other subtypes. Smoking was high frequent in patients with large artery atherosclerosis. Conclusion 6 potentially modifiable risk factors were collectively associated with ischemic stroke and were different among ischemic stroke subtypes. The odds ratios of these risk factors are higher than other countries’ study.
