Introduction: An international study coordinated by the International Agency for Research on Cancer (IARC) and published today in The Lancet Oncology shows that in 2001–2010, childhood cancer was 13% more common than in the 1980s, reaching an annual incidence rate of 140 per million children aged 0–14 years worldwide. Cancer incidence and mortality statistics reported by International Cancer Research Center (2016), over 300,000 children develop cancer worldwide each year, 215000 children aged 0-14 years and 85000 children aged 15-19 years. Internationally comparable data on childhood cancer incidence in the past two decades are scarce. Based on the need for comparison of childhood cancer incidence in Mongolia to the global level, the study aimed to categorize cancer among children aged 0-19 years. Goal: To study the insidence rates and trend from childhood cancer last 10 year in Mongolia Materials and Methods: The study was conducted in 786 new cases childhood who were cancer diagnosed, between 2008 and 2017 year. Age-standardized incidence rates were calculated by the direct method using age-specific incidence rates and weights based on the age distribution of the standard world population Results: Over the past 10 years, childhood cancer accounted for 1.5% of total cancer in Mongolia. By WHO and IARC data, worldwide childhood cancer age standardized rate (ASR) is 106.0, in Mongolia childhood cancer ASR (101.6) is lower than world average. The most common childhood cancers worldwide are: 1st leukemia, 2nd lymphoma, 3rd central nervous system cancer, 4th retinoblastoma, 5th soft tissue cancer. Over the past 10 years the most common childhood cancers in Mongolia are: 1st leukemia, 2nd central nervous system cancer, 3rd joint bone cancer, 4th lymphoma, 5th soft tissue cancer. Our country’s childhood cancer ASR is below compared to other countries, but expected growth rate is gradually increasing (3.0 per year). Conclusions
1. Leukemia is the most common childhood cancer in worldwide and also in Mongolia.
2. By sex, childhood cancer incidence is higher in boys than girls.
3. By age group, childhood cancer incidence is the highest in 0-4 age group.
4. By region, childhood cancer incidence is the highest in central region.
5. The overall incidence of childhood cancer (1 million children) in Mongolia is expected to increase by 3.0 over the next 5 years.

National cancer center of Mongolia has responsibility to produce National cancer registry annual reportwhich is collected cancer reports from primary, secondary and tertiary level of government hospitals andprivate hospitals, laboratories. MCR and indicators of incidence and mortality are important for planningand evaluation of all levels for cancer control, primary prevention, diagnosis, treatment, rehabilitation.ObjectiveThe aim of this study was to determine ASR and ASMRs of cancer incidence and deaths in Mongoliafrom 2008 to 2012 for comparing the results of data.Material and MethodsData on new cancer cases diagnosed in 2008-2012 in permanent residents of Mongolia, collected bycancer registry of the National Cancer Center, were used for the analysis. Incidence and mortality rateswere calculated as mean annual numbers per 100,000 residents. ASRs (Age-standardized incidencerate) and ASMRs (Age-standardized mortality rates) were calculated by the direct method from agespecificincidence and mortality rates, weighted to the World Population standard.ResultsFirst five most frequent cancers (liver, stomach, lung, esophagus, cervix uteri) comprise 76% of all newcancer cases.In males, the most frequent cancer site was liver, followed by stomach, lung, esophageal, colon andrectal cancer. In females, liver is in the first place, followed by stomach, cervical, lung, esophagealcancer.Mean annual crude incidence rate of all cancer sites was 155 per 100 000 population,in males 165, infamale 165 in 2008-2012 years.During this period, mean annual age-standardized incidence rate of all cancer sites was 218,3 per 100000 population, for male 258.9 in female 188.1with higher percentage of men.As we age, morbidity of the cancer increases approximately 2 fold in both sexes and also study revealsmen has more tendency to have cancer than women

IntroductionRheumatoid Arthritis (RA) is chronic systemic inflammatory autoimmune disorder that still remains a disease of unknown etiology and complex disease without a single treatment that is dominated by serious and debilitating sequalae resulting from synovial membrane, cartilage and progressive joint destruction involvement. There is a one major obstacle in elucidating the early events in the pathogenesis of RA has been the lack of definition of the initial features of the disease. To overcome these difficulties, various animal models have been developed. But Collagen Induced Arthritis (CIA) mouse model is known to be the most valuable animal model to explore the pathogenic process, molecular and cellular mechanisms of joint destruction, to discover the immune system respond and activation and to develop new effective treatment methods and useful drugs [1].Materials and Methods:Within this study we have used 40 male mice at age 6-8 weeksfor 0-60 days and divided into following 4 groups which are:I group–CIA induced mouse group treated with Derveger Jirgeruu (Saposhnicovia divaricata) (n=12) II group–CIA induced mouse group treated with Natriisalicylas (10%) (n=12) III group–Healthy control mouse group (n=8) IV group–CIA inducedcontrol mouse group (n=8). To induce CIA model, we have used standard method of Murali /2005/’s design. Standard drug Natriisalicylas (10mg/ 20gr), one of the often used drug anti-inflammatory and Mongolian herbal plant Derveger jirgeruu (Saposhnicovia divaricate) (0.26mg/20gr) were daily administered by orally, starting on day 21 until day 60.To evaluate and compare 2 drug’s anti-inflammatory effect, we have done clinical score evaluation (Kim W.U, 2002), laboratory testing and histological examination of the joints using standard methods.ResultTo summarize the research result, both medications have proven to be as a medication which has anti-inflammatory effect that decreased the signs and symptoms of RA by it is histological and laboratory analysis.Conclusions:1. CIA model was effectively induced, which have proven by clinical signs, laboratory result and histological examination.2. Within this study it has proven that traditional herbal medicine Derveger Jirgeruu (Saposhnicovia divaricate) (0.26mg/20g) have anti-inflammatory effect on CIA induced mouse model of Rheumatoid Arthritis, which have had similar effect asstandard non-steroid medicine Natriisalicylas (10mg/20g).

Introduction: Antimicrobial Resistance (AMR) has emerged as a significant public health and economic issue worldwide, affecting both developed and developing countries. Our research has been motivated by the increasing prevalence of carbapenem-resistant P. aeruginosa, A.baumannii, and K. pneumonia in recent years. Goal: To determine antibiotic susceptibility of the pathogens isolated from wound infection and to detect its multidrug resistance. Material and Method: Samples were collected from patients with wound infections. Pathogens were identified by using the traditional culture methods and the API system with serotypes determined phenotypically. Antibiotic susceptibility was assessed using the disk diffusion method and the MIC to analyse antibiotic resistance. Results: In the study, among 11,221 recorded cases of wound infections in 2023, bacterial pathogens were detected and identified at the species level in 10,339 cases (92.1%).
For identification results showed that A. baummannii were detected from 138 cases (1.3%), 216 cases (2.08%) of Ps. aeruginosa, 5 cases (0.04%) of B. cepacia, 1,383 cases (13.4%) of Enterobacteriaceae, 205 cases (2.0%) of Enterococcus spp., 8,329 cases (80.5%) of Staphylococcus spp., and 63 cases (0.6%) of Streptococcus spp.
Antibiotic susceptibility of these bacteria was assessed and determined multidrug resistance. We found the followings: For A. baumannii were resistant with MDR in 68 cases (49.3%), MRSA in 4,243 cases (51.1%), MDRSta. aureus in 1,805 cases (29.4%), VRE in 34 cases (16.5%), ESBL in 4.6%, KPC in 26 cases (11.1%), FRNF in 24 cases (11.6%), and CRPA in 13 cases (6.3%). Conclusion
1. Of all wound infections reported in 2023 in 92.1% there were detected pathogenic bacteria, of which S.aureus were in 80.5% and E. coli was in 13.4%
2. 60.7% of the pathogenic bacteria detected in wound infections were multidrug-resistant, with MRSA accounting for 51.1% and MDR A.baumannii accounting for 49.3%, indicating high antimicrobial resistance(AMR).

BACKGROUND: There are two general types of age-related macular degeneration: dry and wet. During wet or neovascular age-related macular degeneration new abnormal vessels grow and leak in the macula. As anti-vascular endothelial growth factor (anti-VEGF) was invented, it revolutionized the treatment of nAMD by inhibiting the progress of this disease. The incidence of AMD increases as life expectancy grows and there is a growing need to study this disease. We aimed to evaluate the outcome of anti-VEGF therapy for the treatment of nAMD and the incidence of ocular serious adverse events (SAE) after injections.. METHODS: In our retrospective, single-center study, medical records of patients receiving a single dose of anti-VEGF treatment (Bevacizumab) for nAMD between 17th of April, 2016 and October, 2017 were evaluated. Outcome measures were the change in the baseline visual acuity (VA) score at post-injective month one, incidence of ocular SAE and patients’ baseline characteristics affecting VA. Patients, whose treatment were started before April 2016 and had anti-VEGF treatment for the diseases other than nAMD, were excluded.. RESULTS: 15 eyes in 15 patients between 52 and 85 years of age received single dose of anti-VEGF (Bevacizumab/Avastin) injection. The mean baseline VA improved from pre-injective average of 0.21 to post-injective 1-month average of 0.37 by Snellen. Furthermore, there was no vision loss or other severe adverse effects, such as endophthalmitis, vitreous hemorrhage, retinal detachment, traumatic cataract after 4 weeks. CONCLUSION: Anti-vascular endothelial growth factor therapy has promising short-term outcomes on treating neovascular age-related macular degeneration.

BACKGROUND: Loss of skin elasticity due to redundancy of the upper eyelid (dermatochalasis) and falling of the upper eyelid border to a lower position (blepharoptosis) are often the earliest signs of facial aging. Upper eyelid blepharoplasty is an effective procedure to establish a good eyelid position, and is the most common facial cosmetic procedure [1]. When performing upper eyelid blepharoplasty, eyelid symmetry is essential for a satisfactory surgical outcome. Even if not possible, every surgeon tries to achieve complete symmetry when performing aesthetic eyelid surgery [2]. Several previous studies by surgeons with > 10 years of experience reported how preoperative incision markings should be made to achieve satisfactory surgical outcomes and excellent surgical results for upper eyelid blepharoplasty [3-7]. However, none of these studies investigated naturally occurring asymmetry when applying a preoperative design for upper blepharoplasty incision markings. During the preoperative design step, we noticed certain asymmetric tendencies. We therefore characterised these differences to ensure a more effective preoperative design for upper blepharoplasty incision markings for both eyelids. METHODS: This retrospective study examined 22 patients who underwent bilateral upper blepharoplasty surgery resulting from senile dermatochalasis and/or blepharoptosis. The initial preoperative incision design markings were drawn with the patient sitting upright. Then, with the patient in a supine position, preoperative design photographs were taken. We measured medial canthal excision angle (MCA), maximal lid excision height (MLH), maximal lid excision width (MLW), peak point angle, and peak point distance and compared measurements between both upper eyelids designs using Image J software. RESULTS: The mean MCA for the right side (30.68 ± 10.16°) was significantly different to that for the left side (35.39 ± 13.82°; p < 0.001). The mean MLH for the right side (1.17 ± 0.24 cm) was significantly different to that for the left side (1.24 ± 0.25 cm; p = 0.002). The mean MLW for the right side (0.72 ± 0.19 cm) was significantly different to that for the left side (0.77 ± 0.21 cm; p = 0.011). The mean peak point angle for the right side (15.67 ± 5.09°) was significantly different to that for the left side (18.11 ± 5.49°; p = 0.001). The mean peak point distance for the right side (2.41 ± 0.31°) was significantly different to that for the left side (2.22 ± 0.28 cm; p = 0.001). CONCLUSION: In upper blepharoplasty, the preoperative incision marking design measurements of the left side were significantly greater than those of the right side. The symmetry can therefore be maximised by including the asymmetries in the preoperative design.
