  • Background: Drug-eluting stents are contributing to the exponential growth of percutaneous coronary intervention, and even in the patients with left main coronary artery disease, owing to the decreased restenosis rate. Our study aimed at comparing the one-year results after coronary artery bypass grafting versus percutaneous coronary intervention with drug-eluting stents in patients with left main coronary artery disease. Material and Method: Those patients who underwent coronary bypass surgery or stenting at our hospital under the diagnosis of left main coronary artery disease were divided in two groups. The variables for comparison were the preoperative disease severity, the length of the hospital stay, the early mortality and the cumulative incidence of mortality, myocardial infarction and repeated revascularization. Result: There were 101 cases in the surgery group and 78 cases in the stent group. Age, gender, the risk factors, the left ventricular ejection fraction and the proportion of acute coronary syndrome showed no significant differences between the two groups. The surgery group showed a more severe condition according to the Euroscore, a greater incidence of urgency, a longer hospital stay and a greater incidence of multi-vessel disease. The early mortality and one-year cumulative mortality were not different between the groups. The Euroscore-matched comparison for the surgery group (41 patients) and the stent group (78 patients) showed no significant differences in the Euroscore, age, gender, risk factors and the proportion of acute coronary syndrome. The surgery group in the Euroscore-matched comparison showed more multi-vessel disease and a longer hospital stay. The surgery group showed lower early mortality and lower one-year cumulative mortality, but this was statistically insignificant (0% vs 2.6%, respectively, p=0.55; 0% vs 6.6%, respectively, p=0.30). The rates of repeated revascularization and major adverse events (death or myocardial infarct) were lower in the CABG group, but this was not statistically significant (13.3% vs 6.3%, respectively, p=0.48; 10.0% vs 0%, respectively, p=0.09). Conclusion: Percutaneous coronary intervention using drug-eluting stents in low-risk patients with left main coronary artery disease resulted in a shortened length of the hospital stay, as compared with that of the CABG group of patients. However, the patients who underwent percutaneous coronary intervention using drug-eluting stents showed a tendency for an increased rate of repeated revascularization and higher one-year cumulative mortality. Further studies with large populations and longer follow-up will be necessary to reaffirm our findings.

  • The abnormalities in Hypothalamic-pituitary-adrenal(HPA) axis are associated with many psychiatric symptoms including depression. We present a report of a 71 year old man who was admitted to the psychiatric department presenting symptoms of headache, avolition, loss of energy, psychomotor retardation, poor appetite, insomnia, anxiety resulting from adrenal insufficiency and hypopituitarism. Hypothyroidism and electrolyte disturbance were managed and headache, insomnia, anxiety, GI symptoms were improved. But he remained in anergic state. After discharge, he was readmitted to infection department with high fever and drowsy mentality. Adrenal insufficiency was recognized and he was treated with corticosteroid replacement therapy. Finally his diagnosis was made as panhypopituitarism and overall symptoms were resolved. In this case, we showed how the atypical symptoms resulting from hypopituitarism develop and progress. Hypothyroidism, adrenal insufficiency, and growth hormone deficiency resulting secondarily from panhypopituitarism were associated with various nonspecific symptoms such as loss of energy, fatigue, insomnia, weight loss, decreased appetite etc. In clinical situation, differential diagnosis with depression is needed when clinicians were met a patient with these nonspecific symptoms. It is important that laboratory tests and differential diagnosis with endocrine diseases should be conducted, especially in geriatric patients with nonspecific symptoms like anergia, fatigue, poor appetite and so on.

  • Purpose: We aimed to investigate the correlation between serum cystatin C and clinical manifestations in pediatric patients with urinary tract infections (UTIs). Methods: We studied 137 patients admitted with UTIs from June 2012 to May 2014. Depending on the presence of renal cortical defects on 99m Tc-dimercaptosuccinic acid scintigraphy, we classified patients into non-renal and renal defect groups. Laboratory and clinical parameters were analyzed, including the levels of serum cystatin C. The correlation between cystatin C and other variables was assessed. Results: Serum cystatin C levels did not differ between the non-renal and renal defect groups. In both groups, serum cystatin C levels increased after 4-5 days of treatment, compared with the level at admission (P<0.001). However, mean levels were within normal ranges. The concentration of serum cystatin C positively correlated with serum creatinine and negatively correlated with age (P <0.05). In contrast, there was no correlation between serum cystatin C and other variables. Conclusion: Serum cystatin C does not appear to be a useful biomarker for renal defects in pediatric patients with UTIs. Further studies are necessary to conclude whether serum cystatin C is helpful in predicting deterioration in renal function in pediatric patients with UTIs.

  • Purpose: Despite the fact that enteroviral meningitis is the most common cause of meningitis in children with signs of meningeal irritation and has benign course, most clinicians routinely perform an invasive lumbar puncture (LP) that result in inadequate antibiotic therapy and unnecessary long-term hospitalization. This study was aimed to compare the clinical characteristics of childhood enteroviral meningitis according to LP. Methods: Children over 2 years of age who can clearly express signs of meningeal irritation in the pediatric department of Eulji university hospital from July 2013 and August 2016 were enrolled. The patients were diagnosed by reverse transcriptase polymerase chain reaction in stool and/or cerebrospinal fluid. We retrospectively reviewed their clinical records. Results: A total of 257 patients were diagnosed with enterovirus meningitis and median age was 6.3 (2.1-7.9) years. One hundred fifteen patients (44.7%) with confirmed enterovirus in the stools underwent supportive care without LP. Mostly, there was no statistically significant difference in age, sex, clinical symptoms, except gastrointestinal involvement (abdominal pain, diarrhea), and serologic findings when compared with patients who underwent LP. But patients who underwent LP had longer hospital stay (4 vs 3 days, P<0.001). Four of them (2.8%) were readmitted with back pain and persistent headache, probably related to LP procedure. All patients were discharged without neurologic complications. Conclusion: Rapid detection of enteroviruses in stool specimens that can be easily obtained in children with signs of meningeal irritation may reduce invasive LP.

  • The study was performed to measure structural relationship among service value, brand image, and royalty of patients in regional public hospitals in Korea. Based on the analysis, the study aims to establish strategic direction of the regional public hospitals. Through a review of related literatures, measurement variables were identified, and a path model was developed for the study. Five regional public hospitals were chosen, and questionnaire has been collected from 387 outpatients and 358 inpatients. The study found that service value has a positive direct effect on brand image, and brand image has a positive direct effect on loyalty. Based on the findings, it is desirable for the regional public hospitals should mange the issues with lower level of perception and those with bigger effect, and establish low pricing strategy with improving the quality of service they provide.

  • Purpose: The purpose of this study was to evaluate a community-based cancer patient management program (CBPCMP) which was collaborated between a hospice center and public health centers. Methods: The CBPCMP proceeded on four steps; 1) Signing agreements with three public health centers, 2) Enrolling the domiciliary terminal cancer patients, 3) Providing home hospice service, and 4) Inquiring patient's level of satisfaction. From February 1 to December 31 in 2009, 43 terminal cancer patients were referred and provided with home hospice service. The hospice team made a total of 605 visits. Medical records for each visit and data from satisfaction surveys were analyzed. Results: 76.7% of patients were older than 60 years, and 90.7% of the patients were alert. The level of functional status for 76.7% of patients rated as lower than ECOG grade 1. 62.8% of the patients or their caregivers signed hospice service agreements. On the initial evaluation, the most frequent reasons for referral were general weakness (86.0%), followed by anorexia (72.1%). Nurses visited the patients' most frequently (371 visits), followed by volunteers (216 visits). Nurses provided emotional support and health promotion counseling on 95.1% and 22.9% of visits, respectively. The mean satisfaction score rated by patients and their family was 4.45 out of 5. Conclusion: This study tested CBPCMP in collaboration with hospice centers and public health centers. CBPCMP showed a possibility to improve the quality of end of life care. To insure the quality care, however, the guidelines for home hospice service should be developed.

  • Background: Clopidogrel is widely used just before coronary artery bypass surgery, yet its pharmacological effect can cause postoperative bleeding-related complications. The purpose of this study was to find the effect of preoperative clopidogrel exposure on the blood transfusion requirement and on the rate of reexploration for bleeding control and the rate of readmission caused by bleeding in patients who undergo off-pump coronary artery bypass surgery (OPCAB). Material and Method: This study included 103 patients who had been on clopidogrel preoperatively and they underwent OPCAB by one surgeon from January, 2005 to November, 2007. We divided the patient into two group. Group 1 consisted of 45 patients who stopped cloidogrel 5 days before surgery and group 2 consisted of 58 patients who were taking clopidogrel within 5 days before surgery. Two groups were compared in terms of the bleeding related reoperation rate and the readmission rate, the amount of postoperative bleeding and the required amount of transfusion. Result: There were no significant differences between the two groups concerning the demographic, echocardiographic and hematologic features. There were no significant differences in the postoperative bleeding amount, but the amount of required transfusion was greater in group 2 (p=0.018). While group 1 showed a 0% reoperation rate for hemostasis and 0% readmission rate as related to postoperative bleeding, group 2 showed a 6.9% reoperation and a 5.2% readmission rate, but three were no statistically significant differences between the two groups. Conclusion: Continuous use of clopidogrel did not cause postoperative major bleeding, but can increase the amount of bleeding and the amount of required transfusion postoperatively. We that discontinuation of clopidogrel for a while before elective OPCAB can help the patient's postoperative recovery.

  • Purpose : Although the rotavirus-related neonatal death occurred in western part of Kyeonggi Province recently, there were just a few reports about rotavirus gastroentertis in domestic since 2000. We proposed to investigate changes of epidemiology and clinical features of rotavirus gastroenteritis for the last 2 years. Methods : We selected 166 patients diagnosed as gastroenteritis from January, 2002 to July, 2003 and reviewed the admission records retrospectively such as age distribution, sex ratio, seasonal distribution, admission period, laboratory data and dehydration type in the rotavirus group(RVG) and non-RVG. Results : The percentage of patient under 3 years was 77% on RVG. The non-RVG showed even age distribution(P<0.05). In RVG, patients occurred in March frequently and 52% occurred from January to March. In non-RVG, patients occurred highly in February and July(P<0.05). The average of admission period was higher in RVG than non-RVG(P<0.05). The percentage of patient admitted for over 10 days was 8% in the RVG. In dehydration severity, the RVG showed mild(51%), moderate(44%) and severe(5%) respectively, but non-RVG showed only mild dehydration(P<0.05). The laboratory findings' did not have statistic significance between RVG and non-RVG. Conclusion : Compared to the previous studies, seasonal peak prevalence of rotavirus gastroenteritis changed from autumn to spring and patients over 3 years increased. Therefore, we suggest that there are variable serotypes of rotavirus domestically and there is a need for reinvestigation about clinical features and serotypes of rotavirus gastroenteritis.

  • Purpose: The current study was designed for development of a simplified malnutrition screening tool (SMST) for hospitalized patients using readily available laboratory and patient information and for evaluation of its reliability compared to well-established tools, such as PGSGA and NRS-2002. Methods: Anthropometric and biochemical measurements, as well as a few subjective assessments, of 903 patients who were preclassified by their nutritional status according to PGSGA were analyzed. Among them, a combination of factors, including age, BMI, albumin, cholesterol, total protein, hematocrit, and changes in body weight and food intake, were statistically selected as variables for SMST. Results: According to SMST, 620 patients (68.7%) were classified as the normal group and 283 patients (31.3%) were classified as the malnutrition group. Significant differences in age, albumin, TLC, BMI, hemoglobin, hematocrit, total protein, cholesterol, and length of stay were observed between the two groups. For inter-methods reliability, the screening results by SMST were compared with those by PGSGA and NRS-2002. The comparison with PGSGA and NRS-2002 showed 'Substantial agreement' (sensitivity 94.4%, specificity 88.4%, ${\kappa}$ = 0.747) and 'Moderate agreement' (sensitivity 96.1%, specificity 79.5%, ${\kappa}$ = 0.505), respectively, indicating that SMST held high inter-methods reliability. Conclusion: In conclusion, SMST, based on readily available laboratory and patient information and simple subjective assessments on changes in food intake and body weight, may be a useful alternative tool with a simple but reliable risk index, especially in resource-limited domestic hospitals.

  • Propose : Tsutsugamushi fever is a acute febrile disease, which is caused by O. tsutsugamushi. Recently, this disease is increasingly reported in children. This study was undertaken to investigate clinical features of tsutsugamushi fever in children. Methods : This study involved 17 children with tsutsugamushi fever who were admitted to Masan Samsung hospital between September 1997 and December 2000. We investigated the age, sex ratio, clinical manifestations, laboratory findings, response of therapy and prognosis. Results : The age of patients was $6.9{\pm}3.6$ years, ranging from 6 months to 12 years and male predilection(58.8%) was noted and all cases of patients occured in October or November. The most common symptoms were fever in all cases and headache in 8(47.1%). The most common signs were skin rash in all cases, eschar in 14(82.4%) and lymphadenopathy 8(47.1%). Locations of the eschars were back and inguinal area in each 3 cases, neck and chest in each 2, popliteal area in 2, scalp and thigh in each 1. Laboratory findings included anemia in 1 case, leukopenia and thrombocytopenia in each 5, hematuria and proteinuria in each 1, ESR elevation in 2 and positive CRP in 12, AST elevation in 9 and ALT elevation in 7. Serologic diagnosis was made by passive hemagglutination assay(PHA) in 8 cases(47%) on admission, 4 cases in initial negative group were performed follow-up test at 2nd or 3rd weeks of illness and then all cases of 4 were converted to positive reaction. Clinical improvement was noticed in all cases after treatment to chloramhenicol or doxycycline. Mean duration for defervescence after treatment was $1.4{\pm}0.8$ days. Complications were interstitial pneumonia in 1 case and aseptic meningitis in 3, but all cases of patients were recovered without sequelae or recurrence. Conclusions : Tsutsugamushi fever in children was similiar to adult in the clinical features except male predilection. Early diagnosis and empirical treatment based on clinical manifestations such as fever, skin rash, eschar, lymphadenopathy is important and serologic diagnosis need to perform follow-up test at 2nd or 3rd weeks of illness.
