PURPOSE: The purpose of this study was to identify relationships between quality of sleep, symptom cluster, depression, environmental disorder, and quality of life among hospitalized cancer patients. METHODS: The subjects were 114 patients who underwent chemotherapy for colon cancer, gastric cancer, gynecologic cancer and breast cancer. They were recruited from the cancer center of a university hospital. Data were collected from August 4th to 30th, 2011. The questionnaires included the Korean sleep scale A (quality of sleep), MDASI-K (symptom cluster), the environmental sleep disturbing scale, Zung's depression scale, and the Korean version of EORTC QLQ-C30. The collected data was analyzed by t-test, ANOVA, multiple regression analysis using the SPSS 19.0 program. RESULTS: Functional QOL was negatively associated with symptom QOL (r=-.798, p<.001). Symptom cluster, depression, & spouse (46.3%) were the most powerful predictors for functional QOL (46.3%) and symptom QOL (53.4%). CONCLUSION: It is evident that oncology nurses need to evaluate two dimensions of quality of life for cancer patients, for example, functional and symptom QOL. We recommend nurses develop specific protocols for relieving physical symptoms and alleviating depression, and furthermore test the effectiveness of them.

Myotonic dystrophy is a multisystemic disorder inherited as an autosomal dominant trait. The characteristic clinical features include the presence of myotonia, atrophy of the muscles of the face and the sternocleidomastoids and numerous nonmusclar manifestations such as cataracts, frontal baldness, gonadal dysfunctions and cardiac abnormalities. We experienced one case of myotonic dystrophy with prolonged atrial flutter in 30-year-old male who was admitted because of palpitation. We present this case with reviewing literatures.

BACKGROUND: Nosocomial urinary tract infection (UTI) is the most frequent nosocomial infection and could be prevented through the intensive nosocomial infection control (NIC) or restricting the use of indwelling urinary catheter. The efficiency of the intensive NIC to prevent UTI for the patients with indwelling urinary catheter was investigated. METHODS: Study population consisted of 296 patients with indwelling urinary catheter in the intensive care unit (lCU) who didn't have UTI on admission. The incidence rates of nosocomial UTI were compared between 146 patients being provided with ordinary NIC from March 15 to July 31, 1995 (control group) and 150 patients being provided with intensive NIC from January 16 to October 31, 1996 (NIC group). RESULTS: There was significant decrease in the incidence of nosocomial UTI in the NIC group (35 UTI among 150 patients, 23.8%) than in me control group (68 UTI among 146 patients, 46.6%) (P<0.01). But there were no differences in age distribution, sex, admission route to the ICU and underlying diagnoses between two groups. Interval between insertion of urinary catheter and development of UTI was significantly prolonged in the NIC group (10.0 +/- 3.5 days) than in the control group(7.6 +/- 3.9 days) (p < 0.01) despite there were no differences in the duration of urinary catheterization in two groups. The most common organism isolated from the urine of the patients was Candida tropicalis in both groups and the other organisms were in the order of Enterococcus faecium, Pseudomonas putida, Staphylococcus epidermidis in the control group and in the order of Staphylococcus aureus, Acinetobacter baumannii, Enterococcus faecalis in the NIC group. Four of five Staphylococcus aureus isolated in NIC group were MRSA. CONCLUSION: This study result confirms the efficiency of intensive NIC fur decrease in the incidence of nosocomial UTI in patients with indwelling urinary catheter. But the incidence of nosocomial UTI should be decreased further through the continuous emphasis on NIC and it seems to be necessary to study the effect of each component of NIC with proper control of the risk factors for the development of nosocomial UTI in the future.

BACKGROUND: Stunned myocardium may be mediated by intracellular Ca2+ overloading or oxygen derived-free radicals. Halothane and propofol have been shown to block Ca2+ channels. Propofol is also known to have antioxidant properties. The present study was aimed to investigate the effects of anesthetics on recovery of postischemic, reperfused myocardium in open-chest dogs. Incidence of ventricular arrhythmia upon ischemia and reperfusion was also determined. METHODS: Forty dogs were subjected to 15 min occlusion of left anterior descending coronary artery (LAD) followed by 3 hr reperfusion during halothane (n=10), fentanyl (n=12), or propofol plus fentanyl (n=11) anesthesia. Regional contractile function was assessed using percent systolic shortening (%SS), the preload recruitable stroke work slope (Mw), and peak systolic intramyocardial pressure (IMPs). Diastolic function was evaluated using time constant for isovolumic intramyocardial pressure decline of left ventricle (IMP-tau) and percent post-systolic shortening (%PSS). RESULTS: %SS in the halothane, fentanyl, and propofol-fentanyl groups was similar at 3 hours of reperfusion (58%, 60%, and 55% of baseline value, respectively). Moreover, Mw recovered to the baseline values in the early reperfusion period in all three groups. However, IMP-tau was significantly prolonged in the halothane group throughout the 3 hour reperfusion period, whereas it remained unchanged in the fentanyl and propofol-fentanyl groups. Coronary occlusion was associated with 9, 33, and 0% mortality rate due to ventricular fibrillation upon ischemia and reperfusion in the halothane, fentanyl, and propofol-fentanyl groups, respectively. CONCLUSION: These findings indicate that halothane, but not fentanyl and propofol- fentanyl, impairs myocardial relaxation, while recovery pattern of contractile function do not differ among three groups, and that halothane and propofol reduce reperfusion arrhythmia in the canine model of myocardial stunning.

Objective: The present study aimed to assess the relationship between incidental abnormalities on thoracic computed tomography (CT) and mortality in a general screening population using a long-term follow-up analysis. Materials and Methods: We retrospectively collected the medical records and CT images of 840 participants (mean age ± standard deviation [SD], 58.5 ± 6.7 years; 564 male) who underwent thoracic CT at a single health promotion center between 2007 and 2010. Two thoracic radiologists independently reviewed all CT images and evaluated any incidental abnormalities (interstitial lung abnormality [ILA], emphysema, coronary artery calcification [CAC], aortic valve [AV] calcification, and pulmonary nodules). Kaplan–Meier analysis with log-rank and z-tests was performed to assess the relationship between incidental CT abnormalities and all-cause mortality in the subsequent follow-up. Cox proportional hazards regression was performed to further identify risk factors of all-cause mortality among the incidental CT abnormalities and clinical factors. Results: Among the 840 participants, 55 (6%), 171 (20%), 288 (34%), 396 (47%), and 97 (11%) had findings of ILA, emphysema, CAC, pulmonary nodule, and AV calcification, respectively, on initial CT. The participants were followed up for a mean period ± SD of 10.9 ± 1.4 years. All incidental CT abnormalities were associated with all-cause mortality in univariable analysis (p < 0.05). However, multivariable analysis further revealed fibrotic ILA as an independent risk factor for all-cause mortality (hazard ratio, 2.52 [95% confidence interval, 1.02–6.22], p = 0.046). ILA were also identified as an independent risk factor for lung cancer or respiratory disease-related deaths. Conclusion Incidental abnormalities on screening thoracic CT were associated with increased mortality during the long-term follow-up. Among incidental CT abnormalities, fibrotic ILA were independently associated with increased mortality. Appropriate management and surveillance may be required for patients with fibrotic ILA on thoracic CT obtained for general screening purposes.

BACKGROUND: Myocardial calcium overload during reperfusion may contribute to myocardial stunning. The protective effect of nicardipine against post-ischemic myocardial dysfunction was investigated. METHODS: Twenty-two halothane-anesthetized dogs were subjected to 15 minutes of left anterior descending coronary artery (LAD) occlusion and subsequent 3 hour reperfusion. One group of dogs (n=11) received nicardipine (1 microgram/kg/min) and another group (n=11) received saline (0.5 ml/kg/h) through intracoronary catheter for 1 hour beginning 15 minutes before LAD occlusion. Systolic shortening (%SS) and preload recruitable stroke work slope (Mw), as an index of regional myocardial contractility, and IMP-tau (time constant of myocardial relaxation based on intramyocardial pressure (IMP)) and post-systolic shortening (%PSS), as an index of regional diastolic function, were evaluated. LAD blood flow was measured by Doppler flowmeters as well. RESULTS: Regional systolic as well as diastolic functions during acute myocardial ischemia were similar between the two groups. However, Mw recovered to the baseline value with the onset of reperfusion in the nicardipine group but was significantly decreased throughout the reperfusion period in the controls. After 3 hours of reperfusion, the nicardipine group had recovered 67% of %SS, compared with 20% of the control group. IMP-tau was restored to the baseline value by 60 min of reperfusion in the control group but was significantly prolonged in the nicardipine group throughout the reperfusion period. CONCLUSIONS: Intracoronary nicardipine enhances the recovery of regional contractile function but prolongs myocardial relaxation in the canine model of myocardial stunning.

It was reported that the etiologies of recurrent spontaneous abortion are immunologic factors, endocrinologic problems, anatomical abnormalities, genetic abnormalities, infection, and unexplained factors. Among those etiologic factors, genetic abnormalities occur in about 5% of the couples who experience recurrent spontaneous abortions, and most common parental chromosomal abnormality contributing to recurrent abortion is balanced translocation. The advent of in vitro fertilization (IVF), the development of skills associated with the handling of human embryo, and an explosion of knowledge in molecular biology have opened the possibility of early diagnosis of genetic disease in preimplantation embryos. Therefore preimplantation genetic diagnosis (PGD) is indicated for couples, infertile or not, at risk of transmitting a genetic disease. A case of successful pregnancy and term delivery by PGD using fluorescence in situ hybridization (FISH) technique in patient with recurrent spontaneous abortion due to balanced translocation is presented with brief review of literatures.

BACKGROUND: Polymerase chain reaction (PCR) methods from direct specimen are widely used for the rapid and accurate detection of mycobacteria infection. In this study, we evaluated two domestically developed detection kits for Mycobacterium tuberculosis (MTB) and nontuberculous mycobacteria (NTM) using real-time PCR. METHODS: A total of 348 samples from patients with suspected tuberculosis were tested with real-time PCR over seven months. We performed real-time PCR using the recently developed Anyplex plus MTB/NTM Detection kit (Seegene) with the CFX 96TM Realtime PCR System (Bio-Rad Laboratories) and the conventional AdvanSure TB/NTM real-time PCR kit (LG Life Sciences) with the SLAN Real-time PCR detection system (LG Life Sciences) to evaluate their performance for detecting MTB and NTM. RESULTS: The two real-time PCR systems showed 96.8% concordance rate for MTB-positive, NTM-positive, and negative results. Based on culture results, the sensitivity and specificity for the detection of MTB using PCR were 71.0% and 94.9% for Anyplex plus, and 78.1% and 93.9% for AdvanSure, respectively. For the detection of NTM, the sensitivity and specificity were 33.3% and 98.4% for Anyplex plus, and 51.7% and 97.9% for AdvanSure. Both PCR systems showed high MTB positive results in bronchial washing and sputum samples. CONCLUSION: In detecting MTB and NTM, Anyplex plus MTB/NTM (Seegene) and AdvanSure TB/NTM real-time PCR (LG Life Sciences) showed high concordance rate with each other in all samples. Therefore both detection kits can be used as rapid and reliable detection tool for MTB.

PURPOSE: A graft patency is influenced by various factors; the degree of preoperative ischemia, type of procedure, kinds of the conduit and the stati of inflow and outflow vessels. The aim of this study was to evaluate the patency rate according to the distal anastomosis level, kinds of conduit and the impact of runoff score. METHODS: Between August 1998 and August 2003, 141 lower extremity arterial bypass operations were performed. The runoff scores of the outflow arteries were graded according to the system proposed by the Ad Hoc Committee on Reporting Standards, SVS/ISCVS. The graft patency was determined by clinical examination, and ABI measurements, and with a Duplex scan if required, and assessed by a regular follow-up schedule. RESULTS: The primary patency rates according to the level of distal anastomosis at 1, 3 and 5 years were as follows; femoral artery (FA) 94.8, 87.1 and 87.1%, above-knee popliteal artery (AKPA) 83.7, 79.3 and 68.0%, below-knee popliteal artery (BKPA) 85.9, 64.4 and 42.9%, respectively, and the secondary patency rates; FA 95, 87.6 and 87.6%, AKPA 91.6, 68.3 and 38.6%, BKPA 83.8, 69.9 and 46.6%, respectively. The patency rates of below-knee popliteal bypass showed no statistical difference between each conduit, but showed a tendency to increase in the order: PTFE, vein patch and vein graft. No significant difference in the patency rate was shown except between a runoff score of 1 and above 1 at each level. CONCLUSION: The patency rates for the relatively proximal site of the distal anastomosis were superior to those of the distal site. The choice of conduit influenced the patency of infrapopliteal bypass grafts. The patent outflow vessels and the autogenous vein graft at infrapopliteal artery were more favorable for good graft patency. The recommended runoff score system seems to be revision in order to improve the predictability of a graft patency.

OBJECTIVE: In recent years there has been an enormous increase of neuroscience research using the facial expressions of emotion. This has led to a need for ethnically specific facial expressions data, due to differences of facial emotion processing among different ethnicities. METHODS: Fifty professional actors were asked to pose with each of the following facial expressions in turn: happiness, sadness, fear, anger, disgust, surprise, and neutral. A total of 283 facial pictures of 40 actors were selected to be included in the validation study. Facial expression emotion identification was performed in a validation study by 104 healthy raters who provided emotion labeling, valence ratings, and arousal ratings. RESULTS: A total of 259 images of 37 actors were selected for inclusion in the Extended ChaeLee Korean Facial Expressions of Emotions tool, based on the analysis of results. In these images, the actors' mean age was 38+/-11.1 years (range 26-60 years), with 16 (43.2%) males and 21 (56.8%) females. The consistency varied by emotion type, showing the highest for happiness (95.5%) and the lowest for fear (49.0%). The mean scores for the valence ratings ranged from 4.0 (happiness) to 1.9 (sadness, anger, and disgust). The mean scores for the arousal ratings ranged from 3.7 (anger and fear) to 2.5 (neutral). CONCLUSION: We obtained facial expressions from individuals of Korean ethnicity and performed a study to validate them. Our results provide a tool for the affective neurosciences which could be used for the investigation of mechanisms of emotion processing in healthy individuals as well as in patients with various psychiatric disorders.
