PURPOSE: This study aimed to identify multidimensional factors influencing burnout in intensive care unit(ICU) nurses. METHODS: A descriptive cross-sectional design was used. Data were collected during February 2016 from a convenience sample of 222 tertiary hospital ICU nurses and analyzed using t-test, ANOVA, correlation analysis, and multiple regression analysis. RESULTS: Burnout correlated positively with compassion fatigue (CF)(r=.37, p < .001), and negatively with compassion satisfaction (CS)(r=-.66, p < .001). The regression model explained 57% of the variance in burnout. For individual characteristics in the model, perceived health status (β=-.27, p < .001) and gender (β=.14, p=.028) were the most influential factors for ICU nurses' burnout. In the model with added work-related characteristics, nursing environment (β=-.22, p=.001), perceived health status (β=-.20, p=.001), and satisfaction with department (β=-.19, p=.007) were the most influential factors. Finally, for the model with psychological characteristics added, CS (β=-.56, p < .001) and CF (β=.35, p < .001) were the most influential factors. CONCLUSION: Results reveal that most ICU nurses have a moderate level of CF and a moderate to high level of CS and burnout, and that individual, work-related and psychological factors are relevant in ICU nurses' burnout. Programs or interventions to reduce burnout should be developed taking into account these multidimensional factors.

OBJECTIVE: To determine the prevalence of osteoporosis based on the measurement of bone mineral density (BMD) and to examine the effect of menopausal status on BMD in Korean women. METHODS: Ultra-distal and distal radius BMD was measured by dual energy X ray absorptiometry (osteoplan p-DXA) in 296 women. The result was analysed, retrospectively. We diagnosed osteopenia and osteoporosis according to the WHO criteria. RESULTS: The ultra-distal and distal radius BMD and T score decreased significantly with increase of age. Of women in their thirties, the prevalence of ultra-distal and distal radial osteoporosis were 0%, 6.2%, and in their forties, they were 7.6%, 3.4% and in their fifties, they were 26.6%, 27.9% and of women in their sixties, they were 81.7%, 87.8%. Of women in their forties and fifties, premenopausal women had a higher BMD result than postmenopausal women in the same age group. Of premenopausal women in their forties, the prevalence of osteoporosis were 4.6%, 2.3% and of postmenopausal women in that age, they were 15.6%, 6.3%. Of premenopausal women in their fifties, the prevalence of osteoporosis were 8.3%, 8.3% and of postmenopausal women in that age, they were 29.9%, 31.3%. CONCLUSION: With increasing age, the prevalence of osteoporosis increased and the BMD decreased. In the postmenopausal state, this difference became larger.

BACKGROUND: This study evaluated the clinical characteristics and risk factors associated with community and hospital onset MRSA isolated from patients admitted to a tertiary care teaching hospital. METHODS: The study was carried out on MRSA isolated from clinical specimens of patients admitted into the wards and the intensive care unit in a 2,200-bed tertiary care teaching hospital from January 1st through December 31st, 2007. In order to identify the risk factors associated with MRSA acquisition, the medical records were reviewed. All statistics were computed using SPSS version 14.0. RESULTS: Of the 835 MRSA isolates, 179 (21.4%) were CO-MRSA and 656 (78.6%) were HO-MRSA. Of the 179 CO-MRSA isolates, 6 (3.4%) were CA-MRSA. Multiple logistic regression analysis showed that a history of using medical device or antibiotics within 1 year before the isolation of MRSA were significant risk factors for HO-MRSA, and a history of hospitalization within 1 year before the isolation of MRSA was a significant risk factor for CO-MRSA. Analysis on the antibiotics administered within 1 year before the isolation of MRSA showed that levofloxacin, macrolides, 1st generation cephalosporins, 3rd generation cephalosporins, 4th generation cephalosporins, vancomycin, metronidazole, and carbapenem were all significant risk factors for HO-MRSA and that TMP/SMX was a significant risk factor for CO-MRSA. Of the 6 (3.4%) CA-MRSA isolates, 1 (16.7%) was the pathogen responsible for soft tissue infection. No patients died from the CA-MRSA infection. CONCLUSION: MRSA isolated from clinical specimens of patients admitted into the wards and the ICU in a tertiary care teaching hospital was usually HO-MRSA, CO-MRSA and HO-MRSA usually had at least one of the risk factors associated with MRSA acquisition, and CO-MRSA was mainly HACO-MRSA.

PURPOSE: To investigate whether bone mineral density(BMD) occurs in association with fatty replacement oflower paraspinal muscles and whether it relates with the area ratio(Ps/V) of psoas muscle(Ps) divided by adjacentvertebral body(V). MATERIALS AND METHODS: For the evaluation of osteoporosis, 100 females underwent quantitativeCT. At L1,L2 and L3 levels, the fatty replacement of lower paraspinal muscles was numerically graded and therelationship between this and BMD of the vertebral body was evaluated. The correlation between BMD and Ps/V at L2and L3 levels was also evaluated, as was the relationship between the thickness of subcutaneous fat tissue at L1,L2 and L3 levels. RESULTS: BMD showed significant inverse correlations with the grade of the fatty replacement oflower paraspinal muscles at L1(p<.01), L2 level and L3 level(p<.001). In particular, significant differenceswere established between grade 0 and 2 (p<.05) at L1 level, and between grade 0 and 2, and 1 and 2 (p<.05) at L2and L3 levels. There was markedly low correlation (gamma=.33) between BMD and Ps/V at L3 level(p<.001) and lowercorrelation (gamma=.22) at L2 level(p<.05). At L2 and L3 levels, there was no correlation between the thickness ofsubcutanous fat tissue and BMD or Ps/V. CONCLUSION: The present study demonstrates that there was significantinverse correlation between BMD and fatty replacement of lower paraspinal muscles, and low correlation between BMDand Ps/V.

BACKGROUND: Volume overload results in higher mortality rates in patients on continuous ambulatory peritoneal dialysis (CAPD). The ratio of bioimpedance (RBI) might be a helpful parameter in adjusting dry body weight in CAPD patients. This study examined whether it is possible to distinguish between non-hypervolemic status and hypervolemic status in CAPD patients by using only RBI. METHODS: RBI was calculated as follows: RBI = impedance at 50 kHz/impedance at 500 kHz. Based on the experts’ judgements, a total of 64 CAPD patients were divided into two groups, a non-hypervolemic group and a hypervolemic group. The RBI was measured from right wrist to right ankle (rw-raRBI) by bioimpedance spectroscopy (BCM®, Fresenius Medical Care) before and after the peritosol was emptied. Other RBIs were measured from the right side of the anterior superior iliac spine to the ipsilateral ankle (rasis-raRBI) to control for the electro-physiological effects of peritoneal dialysate. RESULTS: The mean rw-raRBI of non-hypervolemic patients was higher than that of hypervolemic patients in the presence (1.141 ± 0.022 vs. 1.121 ± 0.021, P < 0.001) of a peritosol. Likewise, the mean rasis-raRBI of non-hypervolemic patients was higher than that of hypervolemic patients (presence of peritosol: 1.136 ± 0.026 vs. 1.109 ± 0.022, P < 0.001; absence of peritosol: 1.131 ± 0.022 vs. 1.107 ± 0.022, P < 0.001). CONCLUSION: The volume status of CAPD patients was able to be simply expressed by RBI. Therefore, this study suggests that when patients cannot be analyzed using BCM, RBI could be an alternative.

Enterocolic fistulas are commonly associated with previous surgery, Crohn's disease, diverticulitis, radiation therapy, and malignancy. Here, we report a rare case of enterocolic fistula caused by acute colitis in a hemodialysis patient. A 62-year-old man on maintenance hemodialysis underwent a radical nephrectomy via a paramedian incision due to spontaneous right kidney rupture and was treated with prophylactic antibiotics. On the 16th day of antibiotic therapy, he complained of abdominal pain and diarrhea. Abdominal computed tomography (CT) and ascitic fluid culture revealed acute bacterial peritonitis and sigmoidoscopy showed acute colitis. After treating these diseases with adequate antibiotics, the abdominal pain and ascites were relieved, but the diarrhea persisted. Abdominal CT obtained 7 days later showed an enterocolic fistula. To our knowledge, this is the first case of enterocolic fistula due to acute colitis in Korea.

OBJECTIVE: Our purpose of study was to investigate whether in vivo levels of tumor necrosis factor-alpha in plasma and peritoneal fluid (PF) differ in women with and without endometriosis.Design : Prospective and case-control study. METHODS: Fifty-seven women with laparotomy or laparoscopic findings of minimal to severe endometriosis, and forty-two women with no visual evidence of pelvic endometriosis and with benign gynecologic disease. Tumor necrosis factor-alpha levels in plasma and PF were determined using commercial ELISA. Tumor necrosis factor-alpha concentrations were compared among women with and without endometriosis, and then also were compared according to the revised American Fertility Society classification. RESULTS: Tumor necrosis factor-alpha concentrations were not significantly increased in the plasma and PF of women with endometriosis than in matched normal controls. Tumor necrosis factor-alpha concentrations in endometriosis stage III and IV were sightly increased, which were not increased statistically significant. CONCLUSIONS: Plasma and PF tumor necrosis factor-alpha levels were not different between women with and without endometriosis. Our RESULTS: do not rule out the hypothesis that tumor necrosis factor-alpha may be involved in the pathogenesis of some features of endometriosis.

BACKGROUND: Most of adult patients with chronic immune thrombocytopenic purpura (ITP) that was refractory or relapsed to high-dose corticosteroid have been treated with splenectomy as a 2nd line treatment. However, these patients may have increased morbidity and mortality according to the operation and the increased risk of infection for a lifetime after splenectomy. Despite of the above risks, 30~40% of these patients can't maintain remission. Furthermore, the remission rate after splenectomy is relatively lower in patients with corticosteroid-refractory chronic ITP than that in those patients with corticosteroid-responsiveness. We studied whether danazol, an attenuated androgen, is useful or safe as 2nd line treatment for chronic ITP instead of splenectomy and which factors are associated with the response to danazol. METHODS: Among the patients with chronic ITP who failed corticosteroid therapy in our hospital, 28 patients who received danazol as the 2nd line treatment were analyzed retrospectively. A complete response was defined that the platelet count was increased to 150 x 10(3)/microL, and a partial response was defined that the platelet count was increased above 50 x 10(3)/microL or there was an increased platelet count of more than 20 x 10(3)/microL from the pre-treatment platelet count when the platelet count was above 50 x 10(3)/microL at the time of danazol therapy. RESULTS: The median age of patients was 44 years (range: 19~67) and the number of male patients was 9 (32.1%) and the number of females was 19 (67.9%). The starting daily doses of danazol were variable from 200 to 600mg, though most of the patients were treated with 400mg daily (18 cases, 64.3%). The median duration of danazol therapy was 201.5 days (range: 13~973) and the median duration from ITP diagnosis to danazol treatment was 56 days (range: 20~2,430). Among the accrued 28 patients, 22 patients showed a response to danazol (78.5%); there were 6 patients (21.4%) with a complete response and 16 patients (57.1%) with a partial response. The median duration from danazol treatment to response was 30 days (range: 0~180). The median response duration of danazol treatment was 330 days (95% CI: 182~478) by the Kaplan-Meiyer method. For the danazol-responsive patients, 9 patients (40.9%) remained in remission and 13 patients (59.1%) relapsed. Grade 3~4 toxicity was observed in two patients and three patients stopped danazol because of adverse effects. Hepatotoxicity was the most common toxicity. CONCLUSION: Our findings suggest that danazol is a beneficial, safe choice as the 2nd line treatment for patients with chronic ITP that was refractory or relapsed to corticosteroid.

BACKGROUND: Philadephia chromosome negative chronic myeloproliferative disease (CMPD) is a clonal disorder which includes polycythemia vera (PV), essential thrombocythemia (ET) and idiopathic myelofibrosis (IMF). CMPD has chronic course and different clinical features with low rate of conversion to leukemia. We evaluated the clinical features of CMPD. METHODS: Since 1990, 57 cases of CMPD (18 PV, 35 ET and 4 IMF) were analysed and their clinical characteristics, survival and manner of evolution were evaluated retrospectively. RESULTS: Median age of 57 CMPD patients was 61 (range, 14~90) years and male to female ratio was 1:0.8. Most common clinical manifestations were dizziness/weakness (38.6%), headache (21.2%), cardiovascular events (19.3%) and other symptoms. Treatment with hydroxyurea was most frequent during clinical course of CMPD. Anagrelide was introduced in 12 patients recently. Complication of disease itself and treatment was not frequent except bleeding (3 cases) and thrombotic event (10 cases). Conversion to acute lekemia was none. Ten year overall survival was 83.3% in PV, 60.1% in ET and 4 cases of IMF were all alive at the 6 year follow up. CONCLUSION: CMPD is a chronic disease and long term control is much improved but definitive treatment without complication should be further investigated.

The general concept and initial approach to syncope patients has been mentioned in the general sections. This special sections have been described the characteristics, diagnosis, and treatment with patient education for the each syncope. It has been described in order of reflex syncope, orthostatic hypotension, postural orthostatic tachycardia syndrome (POTS), cardiac syncope, and unexplained syncope. Several clinical issues will have been dealt with in special issues. Neurological assessment is added when the patients were diagnosed with psychogenic pseudosyncope (PPS). Although many childhood syncope caused by reflex syncope, they are also presented as syncope caused by arrhythmic events in patients with congenital heart disease. In the elderly patients, syncope is because of not only a single cause of syncope but a combination of various conditions. In case of a syncope patient visiting the emergency department, a standardized systematic approach will be required to determine whether hospitalize the patient according to the risk of recurrence and the needs for the syncope management unit. We also mention recommendations on the limits of driving, exercising and social life style that are relevant to syncope in all patients. In this guideline, we reviewed the Korean published literatures and European/American guidelines on syncope. We, writing and publishing committee for evaluation and management guidelines of syncope in the Korean Society for Holter and Noninvasive Electrocardiography (KSHNE) under the Korean Heart Rhythm Society (KHRS) are very pleased to be able to publish this guideline. We also hope this guideline will be a good support to manage the syncope patients and a useful trigger for further research in Korea.
