During the Middle East respiratory syndrome (MERS) outbreak in 2015, the Ministry of Health and Welfare (MOHW) of the Republic of Korea provided outbreak information targeting international visitors and foreign residents through multiple channels. The MOHW created a MERS portal website in Korean and English on 10 June 2015; in addition, the existing MOHW website provided English-language press releases beginning 28 May. A toll-free telephone hotline also started service in English on 12 June; it expanded to include 18 other foreign languages on 15 June. This report describes the usage of these multi-language communication channels during this MERS outbreak.

The 2015 Middle East respiratory syndrome (MERS) outbreak in the Republic of Korea, which started with an imported case and spread throughout the country with a total of 186 cases, revealed the vulnerabilities of the health-care system of the country. The situation was compounded by the unique health-care settings in the Republic of Korea, including crowded emergency departments and large numbers of hospital visitors seeking care at multiple hospitals. To assist with the outbreak response, the Ministry of Health and Welfare of the Republic of Korea hosted several international joint missions that provided valuable information and recommendations for MERS control and prevention of future outbreaks. This report briefly summarizes the missions’ outcomes and discusses their positive impacts.

BACKGROUND: This study aims to find the direction of health care and health insurance system reform to strengthen primary care in Korea. METHODS: A comparative analysis was performed on health care system and health insurance system between Korea, Japan, and Taiwan. RESULTS: (1) Functional differentiation between the hospital and the clinic is unclear and many clinics run beds for in-patient care. However, Japan and Taiwan have clear rule on the function of the hospital and the clinic, and only temporary observation beds are allowed for the clinic. (2) Health service delivery system is not defined in the Korean Health care Act. However, Japan and Taiwan have rules on health service delivery system in their health care act. (3) The system of co-payment ceiling is operated in Japan and Taiwan, but not in Korea. And Taiwan has various co-payment system including exemption of co-payment to fulfill the mission of health security. (4) Japan and Taiwan have many fee schedules for enforcing primary care, while Korea has little. CONCLUSION: Health care and health insurance system should be reformed in order to strengthen primary care. Most of all, the role of the hospital and the clinic should be classified. Fee schedule for primary care should be changed to encourage coordinated management of chronic diseases. Reform of co-payment system is also required.

This study was performed to radiographically examine the prevalence of aspiration sites and to evaluate their atomical correlation with the bronchial pattens. Ten healthy beagle dogs were repeatedly radiographed, at weekly intervals, in the left and right lateral, ventrodorsal (VD) and dorsoventral (DV) positions. Three mililiters of iohexol distilled with same volume of saline was infused into the tracheal inlet. Which lung lobe was aspirated was decided upon by the presence of a significant alveolar pattern due to the contrast medium. Alveolar patterns were identified at the left (100%) and right cranial lung lobes (77%) with the dogs in dependant lateral recumbency, at the right caudal lung lobe (71%) with the dogs in VD recumbency and at the right middle lung lobe (59%) with the dogs in DV recumbency, respectively. The anatomical correlation was evaluated by performing computed tomography. The right principal bronchus (165.8 +/- 1.6 degrees) was more straightly bifurcated than was the left principal bronchus (142.7 +/- 1.8 degrees, p < 0.01). In VD position, the right side lung had a greater opertunity to become aspirated. The ventrally positioned right middle lobar bronchial origin was more easily to be aspirated the other laterally positioned ones. We think that these anatomical characteristics can be one of the causes for aspiration pneumonia to occur more frequently in the right side lung.

BACKGROUND: Because of their large size and excellent computerized records of illness and services rendered, the importance of national insurance program is getting much attentions from the public health researchers and the national and local health authorities. In reality, however, most health records from medical insurance program suffer very much from inaccurate disease coding, and therefore, they are practically in no use. METHODS: Pattern of incorrect disease coding of 6 Notifiable Acute Communicable Diseases that believed not to have been occurred in Korea lately was reviewed. The reasons of such incorrect codings in different level of medical institutions were studied. This study also attempted to see how an official intervention asking the medical institutions to correct their coding behavior works by comparing the frequencies of incorrect disease coding before and after the intervention. RESULTS: Study results showed that more incorrect disease codings came from clinics than hospitals, and non-physician personnel in clinics and hospitals seemed to be responsible for most of the incorrect disease codings. Most frequent diseases coded incorrectly such as cholera and poliomyelitis were the ones that physicians and non-physician personnel in the clinics and hospitals had been familiar with for a long time period. CONCLUSION: Even a simple official intervention asking the clinics and hospitals to correct their coding behavior was very effective : total number of incorrect disease codings before intervention (398 cases from 144 institutions) dramatically decreased (14 cases from 8 institutions) after intervention. Significant decrease in incorrect disease coding was found more in small institutions such as clinics and public health facilities than large institutions.

PURPOSE: Despite the benefits of minimally invasive surgery for cervical cancer, there are a lack of randomized trials comparing laparoscopic radical hysterectomy and abdominal radical hysterectomy. We compared morbidity, cost of care, and survival between abdominal radical hysterectomy and laparoscopic radical hysterectomy for cervical cancer. MATERIALS AND METHODS: We used the Korean nationwide database to identify women with cervical cancer who underwent radical hysterectomy from January 1, 2011 to December 31, 2014. Patients who underwent abdominal radical hysterectomy were compared to those who underwent laparoscopic radical hysterectomy. Perioperative morbidity, the use of adjuvant therapy, and survival were evaluated after propensity score balancing. RESULTS: We identified 6,335 patients, including 3,235 who underwent abdominal radical hysterectomy and 3,100 who underwent laparoscopic radical hysterectomy. The use of laparoscopic radical hysterectomy increased from 46.1% in 2011 to 51.8% in 2014. Patients who were younger, had a more recent year of diagnosis, and were treated in the metropolitan area were more likely to undergo a laparoscopic procedure (p < 0.001). Compared to abdominal radical hysterectomy, laparoscopic radical hysterectomy was associated with lower rates of complication, fewertransfusions, a shorter hospital stay, less adjuvant therapy, and reduced total medical costs (p < 0.001). Laparoscopic surgery was associated with a better overall survival than abdominal operation (hazard ratio, 0.74; 95% confidence interval, 0.64 to 0.85). CONCLUSION: In the postdissemination era, laparoscopic radical hysterectomy was associated with more favorable morbidity profiles, a lower cost of care, and comparable survival than abdominal radical hysterectomy.

Objective: The need to perform genetic sequencing to diagnose the polymerase epsilon exonuclease (POLE) subtype of endometrial cancer (EC) hinders the adoption of molecular classification. We investigated clinicopathologic and protein markers that distinguish the POLE from the copy number (CN)-low subtype in EC. Methods: Ninety-one samples (15 POLE, 76 CN-low) were selected from The Cancer Genome Atlas EC dataset. Clinicopathologic and normalized reverse phase protein array expression data were analyzed for associations with the subtypes. A logistic model including selected markers was constructed by stepwise selection using area under the curve (AUC) from 5-fold cross-validation (CV). The selected markers were validated using immunohistochemistry (IHC) in a separate cohort. Results: Body mass index (BMI) and tumor grade were significantly associated with the POLE subtype. With BMI and tumor grade as covariates, 5 proteins were associated with the EC subtypes. The stepwise selection method identified BMI, cyclin B1, caspase 8, and X-box binding protein 1 (XBP1) as markers distinguishing the POLE from the CN-low subtype. The mean of CV AUC, sensitivity, specificity, and balanced accuracy of the selected model were 0.97, 0.91, 0.87, and 0.89, respectively. IHC validation showed that cyclin B1 expression was significantly higher in the POLE than in the CN-low subtype and receiver operating characteristic curve of cyclin B1 expression in IHC revealed AUC of 0.683. Conclusion BMI and expression of cyclin B1, caspase 8, and XBP1 are candidate markers distinguishing the POLE from the CN-low subtype. Cyclin B1 IHC may replace POLE sequencing in molecular classification of EC.

This study was conducted to evaluate the usefulness of coronary arterial profiles from normal dogs (11 animals) and canines (six dogs) with experimental myocardial infarction (MI) induced by ligation of the left coronary artery (LCA). Blood velocity of the LCA and right coronary artery (RCA) were evaluated following transthoracic pulsed-wave Doppler echocardiography. The LCA was observed as an infundibular shape, located adjacent to the sinus of Valsalva. The RCA appeared as a tubular structure located 12 o'clock relative to the aorta. In normal dogs, the LCA and RCA mean peak diastolic velocities were 20.84 +/- 3.24 and 19.47 +/- 2.67 cm/sec, respectively. The LCA and RCA mean diastolic deceleration times were 0.91 +/- 0.14 sec and 1.13 +/- 0.20 sec, respectively. In dogs with MI, the LCA had significantly (p < 0.01) lower peak velocities (14.82 +/- 1.61 cm/sec) than the RCA (31.61 +/- 2.34 cm/sec). The RCA had a significantly (p < 0.01) rapid diastolic deceleration time (0.71 +/- 0.06 sec) than that found in the LCA (1.02 +/- 0.22 sec) of MI dogs. In conclusion, these profiles may serve as a differential factor for evaluating cardiomyopathy in dogs.

OBJECTIVE: To evaluate the cost-effectiveness of nodal staging surgery before chemoradiotherapy (CRT) for locally advanced cervical cancer in the era of positron emission tomography/computed tomography (PET/CT). METHODS: A modified Markov model was constructed to evaluate the cost-effectiveness of para-aortic staging surgery before definite CRT when no uptake is recorded in the para-aortic lymph nodes (PALN) on PET/CT. Survival and complication rates were estimated based on the published literature. Cost data were obtained from the Korean Health Insurance Review and Assessment Service. Strategies were compared using an incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed, including estimates for the performance of PET/CT, postoperative complication rate, and varying survival rates according to the radiation field. RESULTS: We compared two strategies: strategy 1, pelvic CRT for all patients; and strategy 2, nodal staging surgery followed by extended-field CRT when PALN metastasis was found and pelvic CRT otherwise. The ICER for strategy 2 compared to strategy 1 was $19,505 per quality-adjusted life year (QALY). Under deterministic sensitivity analyses, the model was relatively sensitive to survival reduction in patients who undergo pelvic CRT alone despite having occult PALN metastasis. A probabilistic sensitivity analysis demonstrated the robustness of the case results, with a 91% probability of cost-effectiveness at the willingness-to-pay thresholds of $60,000/QALY. CONCLUSION: Nodal staging surgery before definite CRT may be cost-effective when PET/CT imaging shows no evidence of PALN metastasis. Prospective trials are warranted to transfer these results to guidelines.

OBJECTIVE: The aim of this study was to examine the clinical characteristics of patients with ovarian cancer who underwent enterostomy. METHODS: Via medical record review, we obtained clinical information of 51 ovarian cancer patients who underwent enterostomy in our hospital, from 1990 to 2006. We compared the clinical characteristics according to the indication of enterostomy: primary cytoreduction (PC), secondary cytoreduction (SC), and palliative only (PO). In addition, we investigated the correlations among clinical characteristics to find prognosticators. RESULTS: Patients were older (P=0.061), had less upper gastrointestinal symptoms (P=0.000), underwent colostomy rather than ileostomy (P=0.037), and received more postoperative chemotherapy (P=0.000) according to the following order: PC, SC, PO groups. Older patients had more postoperative complications (P=0.035). In the PC group, older patients had less chance of optimal debulking (P=0.020). In the PO group, preoperative gastrointestinal symptoms were associated with the type of enterostomy. CONCLUSIONS: Clinical characteristics of patients were different according to the indication of enterostomy. Careful examination of clinical characteristics and gastrointestinal symptoms might be helpful to predict the postoperative quality of life.
