Purpose: In order to provide a systematic and standardized treatment course for MVD patients, a critical pathway (CP) program was developed and the results of its long term application were analyzed. Methods: This was a methodological study. The CP was established and applied to 75 (step I) and 1,216 (step II). Another group of 56 with similar features was used as a control group. Results: The application of CP turned out to be useful in many regards: the rate of hearing loss was reduced from 1.8% to 0% (step I) and 0.5% (step II), and low cranial nerve palsy was reduced from 1.8% to 1.3% and 0.7%, respectively. The length of hospitalization decreased by 2.56 days (25.2%) for step I and 3.05 days (30.0%) for step II. Days of ICU stay were reduced by 7.9% and 1.8%. The total cost per patient was reduced by 14.8% (step I). The cost per day was increased by 13.7% and 52.4%. An increase in the patient satisfaction index was noted, as shown in the ICU information guide (p=.002). Conclusion: The development and application of CP was found to improve the quality of medical treatment and the efficacy of hospital management in MVD patients. Well organized and efficient system and multidisciplinary teamwork are the key component of the successful application of CP.

Purpose: Most of the patients who underwent surgery feels variable kinds of fear or anxiety; an uncomfortable mood state that happens without specific object affects patient's satisfaction before and after the surgery. As music therapy is rather noninvasive method generally used in reducing patient's anxiety, the authors researched about the extent of anxiety with the change of vital sign before the operation while comparing with the cases of patients who took the music therapy at closed reduction under general anesthesia. Method: We divided the patients in 4 groups; A with the premedication (Midazolam, Dormicum$^{(R)}$) before the operation, B with the premedication and music therapy, C with only music therapy, D with no premedication or therapy. And we measured the vital signs after the arrival at the operation room, after induction and 20 minutes after the operation. Also we observed the changes of anxiety index with the STAI (State Trait Anxiety Inventory)-K (Korea)YZ 1 hour before and 8 hours after the surgery. Result: The group B showed the least changes in blood pressure as the group D showed the highest change. Both group C and A showed increase in blood pressure but the upswing in group A was lower than group C. At the change of pulse rate group B showed the lowest upswing also group D showing the highest. Group B showed quite a few upswing but lower than group D, but, at the same time, group A showed lower upswing when comparing two cases. After analysis of STAI-KYZ score, the anxiety relatively decreased in group B and C in comparison with group D. And the index of anxiety state of group A showed just as much to group D. Conclusion: The music therapy is better healthcare method compared to other therapies in reducing anxiety also with satisfying effect who underwent operation. The authors recommend music therapy assisted with use of premedication for better relief of anxiety.

To evaluate the current practices of the tube feeding and the status of tube feeding patient 76 adult in-patients at 6 hospitals located in Seoul and Chung-buk province were examined through reviewing patient charts observing patients and interviewing patients nurses dietitians patients' family or care-givers. The results were as follows : 1) An average age of the patients was 54.5 years with 41% over 60 years old. Patients with decreased mental status dysphagia esophageal obstruction and respiratory problem were fed by tubes. 2) The range of duration of tube feeding is between 4 days and 6 years. Most patients were received formula through nasogastric tube(89.5%) while 7.9% of gastrostomy and 2.6% of jejunostomy. Administration method for formula were bolus feeding regardless of the route of formula delivery. 3) Mean total calories received for men were 1590 kcal and 1450 kcal for female. Mean volume per meal was 282m, l and mean frequency of feeding was 5.68 while mean feeding interval 3$\frac{1}{4}$ hours and mean rate of infusion 68.4ml/min. All patients received hospital-blenderi-zed formula as the major source of nutrition. Home-blenderized formula and commercial formula as a supplement were used 35%, 13.2% respectively. 4) Thirty-eight percent of patients was hypoalbuminemia and 61% was at the moderate level of deficiency in hemoglobin. 5) Complications associated with tube feeding were diarrhea (22.4%) constipation(21.1%) vomiting(11.8%) and so on. 6) Serum albumin levels of patients who have complications associated with tube feeding were significantly lower than those of patients without complications In planning a tube feeding regimen the type of a formula must be integrated with both a delivery system and a protocol for administering the tube feeding. the multidisciplinary effort required to deliver enteral therapy is essential to improve current practices used at hospitals.

Foreign body (FB) ingestion of children is a common pediatric emergency requiring medical attention. Pediatric emergency physicians and gastroenterologists often encounter nervous and distressed situations, because of children presenting with this condition in the common clinical practice. When determining the appropriate timing and indications for intervention, physicians should consider multiple patient- and FB-related factors. The utilization of a flexible endoscopy is considered safe and effective to use in these cases, with a high success rate, for the effective extraction of FBs from the gastrointestinal tract of a child. Additionally, a Foley catheter and a magnet-attached Levin tube have been used for decades in the case of FB removal. Although their use has decreased significantly in recent times, these instruments continue to be used for several indications. Using a Foley catheter for this purpose does not require special training and does not necessarily require sedation of the patient or fluoroscopy, which serve as advantages of utilizing this method for foreign object retrieval. An ingested magnet or iron-containing FB can be retrieved using a magnet-attached tube, and can be effective to retrieve an object from any section of the upper gastrointestinal tract that can be reached. Simple and inexpensive devices such as Foley catheters and magnetattached tubes can be used in emergencies such as with the esophageal impaction of disk batteries if endoscopy cannot be performed immediately (e.g., in rural areas and/or in patients presenting at midnight in a facility, especially in those without access to endoscopes or emergency services, or in any situation that warrants urgent removal of a foreign object).

Purpose: The present study aimed to study the immunogenicity of the ChAdOx1 nCoV-19 vaccine in patients with hematologic malignancies. Materials and Methods: This prospective cohort study of hematology patients aimed to evaluate their antibody levels against the receptor-binding domain of the severe acute respiratory syndrome coronavirus 2 spike protein and seroconversion rates following two doses of the ChAdOx1 nCoV-19 vaccine. Between June and July 2021, we enrolled 61 patients and included 44 patients in our analysis. Antibody levels were assessed 8 and 4 weeks after the first and second injections, respectively, and compared with those of a healthy group. Results: Eight weeks after the first dose, the geometric mean antibody level was 1.02 binding antibody units (BAU)/mL in the patient group and 37.91 BAU/mL in the healthy volunteer group (p<0.01). Four weeks after the second dose, the geometric mean antibody level was 9.44 BAU/mL in patients and 641.6 BAU/mL in healthy volunteers (p<0.01). The seroconversion rates 8 weeks after the first dose were 27.27% and 98.86% in the patient and healthy volunteer groups, respectively (p<0.001). The seroconversion rate 4 weeks after the second dose was 47.73% in patients and 100% in healthy volunteers. Factors leading to lower seroconversion rates were rituximab therapy (p=0.002), steroid therapy (p<0.001), and ongoing chemotherapy (p=0.048). Factors that decreased antibody levels were hematologic cancer (p<0.001), ongoing chemotherapy (p=0.004), rituximab (p<0.001), steroid use (p<0.001), and absolute lymphocyte count <1,000/mm³ (p=0.009). Conclusion: Immune responses were impaired in individuals with hematologic malignancies, particularly patients undergoing ongoing therapy and B-cell-depleting therapy. Additional vaccinations should be considered for these patients, and further investigated.

Objectives: This study aimed to verify the impact of dental health care insurance coverage policy by analyzing the changes in dental care utilization and expenditures over 5 years from 2012 to 2016, when the dental health insurance coverage expansion policy was implemented. From the national cohort data collected by the Korea Health Panel Survey, a retrospective study was conducted for all household members using dental services. Methods: This study statistically verified the difference in the dependent variables by frequency analysis, chi-square test, t-test, and one-way analysis of variance (SPSS version 22, IBM Co. USA, p<0.05). Results: The annual utilization rate steadily increased from 23.4% to 26.1% between 2012 and 2016. Although there were differences in utilization rates by gender, age, and income level, patients kept using the dental services in 2016 regardless of the type of health insurance. The average annual copayment for patient expenditures (out-of-pocket amount) increased from ￦463,844 to ￦537,401 in 2012 and 2016, respectively. Of the dental care expenditures over 5 years, the ratio of uninsured expenses by the elderly decreased from 38.5% to 25.9%, and the national health insurance service coverage increased from 40.3% to 49.1%. Conclusions: Although this policy did not reduce overall patient expenditures, it has been found that there was a positive effect on the elderly and low-income groups; it increased the utilization and access to dental services.

Background: For AVR using conventional prosthetic valves in adult patients with a narrow aortic root, aortic root enlargement is necessary to reduce postoperative pressure gradient across the aortic valve (ΔP). An evaluation of early and mid-term results of aortic root enlargement with AVR and echocardiographic follow up of ΔP and left ventricular function was performed. Method: From Aug. 1991 to Feb. 1998, eighteen patients aged 17 to 59 years(mean, 38$\pm$12 years) underwent Manouguian procedure with AVR. Aortic annular circumstance was enlarged 10.0mm to 18.0mm(mean, 12.6$\pm$6.3mm). Eight patients(44.0%) had NYHA class III status before operation, and seven cases of them underwent concomitant MVR. Valve pathology was ASr in 6 cases, AS in 4 cases, nd ASr+MSr in 8 cases. Replaced valve size was 21mm in 8 cases and 23 mm in 10 cases, and St. Jude Medical mechanical valve was used in 10 cases and Carbomedics in 8 cases. Result: Follow-up duration was 6 to 57 months (mean, 26$\pm$18 months), and total follow-up was 287 patient-year. There were one hospital death and one late death, therefore, actuarial survival rate was 85.7% at 56 months. Peak ΔP wad decreased significantly at postoperative mid-term period as 13$\pm$5mmHg, compared with thepreoperative one (42$\pm$8mmHg) (p<0.01). LVM(gm/$m^2$) was also diminished as 35.8%(115$\pm$36gm/$m^2$)at postoperative mid-term period, compared with preoperative one (179$\pm$56gm/$m^2$)(p<0.05). Conclusion: There were no specific complications related to the procedure. And we could have adequate enlargement of aortic annulus to suitable prosthetic valve that have no effect of patient-prosthese mismatch.

As medical insurance had been implemented for Magnetic Resonance Imaging (MRI) from January 1, 2005, this study investigated whether there had been any change in the amount of the medical care utilization of patients who undertook MRI before and after the insurance coverage, and was to examine factors affecting the amount of medical care utilization of MRI. Data were collected from patients who undertook MRI before and after the insurance coverage for a year at a general hospital in Kyeanggi-do. $X^2$ and t-test were used for the analysis of their general characteristics, the number of MRI, and its medical costs before and after the insurance coverage, and hierarchical multiple regression analysis for the factors affecting the amount of the medical care utilization of MRI. The results of this study were as follows. First, the number of MRI after the insurance coverage was significantly decreased. Second, there was no significant difference in the total medical costs of MRI after the insurance coverage, but a significant difference was found in patient's share of medical costs. Third, six variables were found to be affecting the amount of the medical care utilization of MRI, and the variables showed to lead the number of MRI decrease after the insurance coverage. These six factors explained 21.4% of the total number of MRI. As MRI had been covered by insurance, the use of MRI and patient's share of the costs were deceased, but the total medical costs were not affected. Reasons for that could be found in that MRI insurance, different from the case of CT insurance coverage, was allowed not to cover some items and the kinds of diseases subjected to the insurance coverage were extremely limited, lowering insurance prescription rate. In addition to that, the average medical cost of MRI was not changed after the insurance coverage. Therefore, as future measures for the MRI insurance, coverage, it should be considered to allow insurance coverage to no coverage items and to expand the scope of benefit coverage, or to lower patient's share of the costs. Furthermore, researches should be done to explore how recipients will act and how suppliers will react if the coverage is expanded, including expanding the scope of coverage and reducing patient's share of the costs, as well as to conduct research on its economic analysis according to case mix.

연구목적: 64 절편 MDCT를 이용한 심장 CT의 진단일치도를 알아보고, 심박동수와 관상동맥 석회화가 진단일치도에 영향을 미치는지 확인하여 심장 CT 검사 시 기초 자료로 활용하고자 함이다. 연구방법: 심장 CT와 관상동맥 조영술을 함께 시행한 178명(남자 84명, 여자 94명)을 대상으로 심장 CT에서 관상동맥 협착과 심박동수, 석회화 수치를 측정하였고, 관상동맥조영술에서 좌전하행동맥, 좌회선동맥, 우관상동맥의 유의한 협착($\geq50%$)이 있는지 확인하였다. 관상동맥 조영술의 결과를 표준으로 심장 CT의 민감도, 특이도, 양성예측도, 음성예측도, kappa index($\kappa$)를 계산하였다. 연구결과: 환자별 협착의 정도를 평가한 결과 심장 CT의 정확도는 96.6%였다. 혈관별로는 LAD, LCX, RCA 각각 86.5%, 84.3%, 92.1%로 높은 진단일치도를 보였다. 체질량지수와 혈압은 심장 CT의 진단일치도에 영향을 미치지 않았다. 심박동수는 60/min 미만에서 정확도 90.1%, $\kappa$값 0.78이었고, 70/min 이상에서는 정확도가 75.8%, $\kappa$값 0.52이었다. 관상동맥 석회화지수 100 미만에서는 정확도가 91.3%, $\kappa$값 0.81이었고, 석회화지수 400 이상에서는 정확도 68.6%, $\kappa$값 0.33으로 떨어졌다. 결론: 64 절편 MDCT를 이용한 심장 CT는 관상동맥 조영술과 거의 비슷한 진단일치도를 나타냈다. 하지만 심박동수 70/min 이상, 관상동맥 석회화지수 400 이상에서는 진단일치도가 저하되었기 때문에 심장 CT 검사 시 심박동수와 관상동맥 석회화지수를 확인하여 검사하여야 하고, 심박동수가 70/min 이상이면 베타차단제를 사용하여 심박동수를 조절하여야 한다.
