The purpose of this study was to provide basic data useful to the training of hospice care members. For this study carried out to investigate the degree of death orientation of hospice care members. The subjects of study were 22 nurses, 85 clergies, 59 volunteers who registered on Hospice Education Programs. The data were analysed by descriptive analysis, t-test, ANOVA, Duncan test and Person's correlation coefficient. The results of the study can be summarized as follows; 1. The degree of death orientation were 85.95 in nurses group, 73.05 in clergies group, and 88.49 in volunteers group. So, clergies group has more positive death orientation than others. 2. The degree of death orientation showed significant differences between age group(F=4.62, p=.004), education program group(F=27.25, p=.000), and religiosity(t=3.77, p=.000). There were no significant differences between the degree of death orientation and the others general characteristics of hospice care members. In conclusion, the urgent need for educational preparation of death orientation and spiritual care of hospice care team, especially volunteers group and nurses group is emphasized. Furthermore, all of the hospice care members those who complete the hospice education program, should be performed efficient hospice care intervention for dying patients and their families.

OBJECTIVES: The percentage of positional sleep apnea in obstructive sleep apnea (OSA) varies in different reports from 9% to 60%. If there is a positional dependency in patients with OSA, positional therapy alone could be successful in treating about 50% of all OSA cases. The aim of this report is to compare anthropomorphic and polysomnographic data between the positional sleep apnea group and non-positional sleep apnea group with OSA whose conditions were diagnosed in our sleep clinic. METHODS: This is a retrospective study of anthropomorphic and polysomnographic data of patients with OSA who was performed a nocturnal polysomnography. Positional sleep apnea was defined as having a supine apnea-hypopnea index (AHI) of twice or more compared to the AHI in the non-supine position. The patients were divided in the positional sleep apnea group and the non-positional sleep apnea group. RESULTS: In 101 patients with OSA, 81 were male, and the mean age was 49.2+/-11.9 years. Seventy-six (75.2%) were diagnosed as the positional sleep apnea. Waist to hip ratio and body mass index (BMI) were significantly higher in non-positional sleep apnea group. The frequency of severe OSA was significantly higher in this group. In the positional sleep apnea group, nocturnal sleep quality was better preserved, and consequently these patients were less sleepy during daytime. AHI was significantly lower and minimal arterial oxygen saturation during sleep was significantly higher in this group. CONCLUSION: The percentage of positional sleep apnea in OSA was 75.2%. AHI, BMI, and waist to hip ratio were lower in the positional sleep apnea group. These patients have less severe breathing abnormalities than the non-positional sleep apnea group in polysomnography.

OBJECTIVES: The Berlin Questionnaire (BQ) has been used to help identify patients at high risk of having sleep apnea in primary care. But it has not been validated in a sleep clinic for Korean patients. The aim of this study is to evaluate the usefulness of the BQ as a screening tool for obstructive sleep apnea (OSA) for Korean patients in a sleep clinic. METHODS: The BQ was prospectively applied to 121 subjects with OSA suspicion who visited to our sleep clinic. All subjects performed overnight polysomnography. OSA was defined as an apnea-hypopnea index (AHI) > or =5. We investigated the sensitivity, specificity, positive and negative predictive values of the BQ according to severity by AHI. RESULTS: In 121 subjects, 73.6% were males, with a mean age of 48.8+/-13.0 years. Twenty-five (20.6%) patients did not have OSA (AHI<5), 30 (25%) patients had mild OSA (AHI> or =5 and <15), 26 (21.4%) had moderate (AHI> or =15 and <30), and 40 (33%) had severe OSA (AHI> or =30). The BQ identified 69.4% of the patients as being at high risk for having OSA. The sensitivity and specificity of the BQ were 71.9% and 40%, for AHI> or =5, 75.8% and 38.2% for AHI> or =15, 77.5% and 34.6% for AHI> or =30, respectively. The positive and negative predictive values of the BQ were 82.1% and 27.0% for AHI> or =5, respectively. Positive and negative likelihood ratios were 1.2 and 0.7, and the overall diagnostic accuracy of the BQ was 65.3%, using an AHI cut-off of 5. CONCLUSION: Due to modest sensitivity and low specificity, the BQ does not seem to be an appropriate tool for identifying patients with obstructive sleep apnea in a sleep clinic population.

PURPOSE: The purpose of this study is to investigate clinical features and causative organisms in febrile infants younger than three months, to help identification of high risk patients for serious bacterial infection (SBI). METHODS: A total of 313 febrile infants younger than three months, who had visited Seoul National University Children's Hospital from January 2008 to December 2010 were included. Clinical features, laboratory findings, causative organisms, and risk factors of SBI were analyzed by retrospective chart review. Causative bacterial or viral pathogens were identified by gram stain and cultures, rapid antigen tests, or the polymerase chain reaction from clinically reliable sources. RESULTS: Among 313 infants, etiologic organisms were identified in 127 cases (40.6%). Among 39 cases of bacterial infections, Escherichia coli (66.7%) and Streptococcus agalactiae (12.8%) were common. Enterovirus (33.7%), respiratory syncytial virus (19.8%), and rhinovirus (18.8%) were frequently detected in 88 cases of viral infection. Patients with SBI (39 cases) showed significantly higher values of the white blood cell count (14,473+/-6,824/mm3 vs. 11,254+/-5,775/mm3, P=0.002) and the C-reactive protein (6.32+/-8.51 mg/L vs. 1.28+/-2.35 mg/L, P<0.001) than those without SBI (274 cases). The clinical risk factors for SBI were the male (OR 3.7, 95% CI 1.5-8.9), the presence of neurologic symptoms (OR 4.8, 95% CI 1.4-16.8), and the absence of family members with respiratory symptoms (OR 3.6, 95% CI 1.2-11.3). CONCLUSION: This study identified common pathogens and risk factors for SBI in febrile infants younger than three months. These findings may be useful to guide management of febrile young infants.

OBJECTIVES: Clinical Practice Guidelines (CPGs) are an effective tool for minimizing the gap between a physician's clinical decision and medical evidence and for modeling the systematic and standardized pathway used to provide better medical treatment to patients. METHODS: In this study, sentences within the clinical guidelines are categorized according to a classification system. We used three clinical guidelines that incorporated knowledge from medical experts in the field of family medicine. These were the seventh report of the Joint National Committee (JNC7) on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure from the National Heart, Lung, and Blood Institute; the third report of the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults from the same institution; and the Standards of Medical Care in Diabetes 2010 report from the American Diabetes Association. Three annotators each tagged 346 sentences hand-chosen from these three clinical guidelines. The three annotators then carried out cross-validations of the tagged corpus. We also used various machine learning-based classifiers for sentence classification. RESULTS: We conducted experiments using real-valued features and token units, as well as a Boolean feature. The results showed that the combination of maximum entropy-based learning and information gain-based feature extraction gave the best classification performance (over 98% f-measure) in four sentence categories. CONCLUSIONS: This result confirmed the contribution of the feature reduction algorithm and optimal technique for very sparse feature spaces, such as the sentence classification problem in the clinical guideline document.

PURPOSE: To analyze and compare the immunohistochemical distributions of HO-1 and HO-2 with the developmental process of retina, focusing on the time of birth and opening eyes because it is the time of the exposure to hyperoxia and light exposure. METHODS: The retina of 16-day-old embryo, 18-day-old embryo, 20-day-old embryo and postnatal rats at 0 day, 5 days, 10 days, 15 days, 20 days, 1 month, 2 months, 3 months were examined by hematoxylineeosin staining and immunohistochemistry of HO-1 and HO-2. RESULTS: Similar distribution of HO-1 and HO-2 from embryo to mature retina were observed. It was observed that HO-1 and HO-2 was contained in ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer and pigment layer of the mature retina. In the developmental process, reactivity was observed in the cell body of ganglion cells after 0 day of its birth. The reactivity was increased after 5 days of its birth, staining was observed in nerve cell and nerve fiber of ganglion cell layer, inner plexiform layer, inner segment of neuroblastic layer, pigment layer at this time. Reactivity of ganglion cell layer and pigment layer was increased intensively after 15 days of its birth and weak reactivity in some of horizontal cells and amacrine cells in inner plexiform layer was observed. The same distribution as that of mature retina was observed after 20 days of its birth. CONCLUSIONS: HO-1 and HO-2 expression was temporally and spatially correlated with the normal development of retina in rats. HO was concerned with the structure and function of retinal development by the activation of its products and with anti-oxidant mechanism on the time of birth and opening eyes.

OBJECTIVES: To determine changes in the incidence and pattern of eclampsia in Il Sin Christian Hospital over a 46-year period. METHODS: Information was collected from medical records of the 1910 eclamptic patients among 233,613 deliveries in Il Sin Christian Hospital from Jan. 1 1953 to Dec. 31 1998. Incidence, presentation, and management of eclampsia were reviewed retrospectively, and maternal mortality rate and perinatal mortality rate were calculated. Statistical analysis was done by Chi-squared and Fisher's exact test through two by two tables looking at relative changes between each study period. RESULTS: The overall incidence of eclampsia was 81.8 per 10,000 deliveries. The incidence of eclampsia had increased from 137.3/10,000 in 1953-1962 to 278.4/10,000 in 1963-1972, but the rate had reduced to 6.5/10,000 in 1993-1998. There was a statistically significant fall in the rate of eclampsia every decade between 1973 and 1992, but there has been steady decrease in the last study period. Convulsion occurred antepartum in 54% of patients, intrapartum in 29% and postpartum in 17%. With the reduction in the proportion of antepartum eclampsia, there has been a relative increase in that of intrapartum and postpartum eclampsia. Maternal death occurred in 59 cases among eclampsia, and maternal mortality rate was 3.1%. Maternal mortality rate had significantly decresed from 11.1% in 1953-1962 to 3.8% in 1963-1972, and there has been no maternal death from eclampsia since 1986. Postpartum eclampsia had increased death risk compared with antepartum or intrapartum eclampsia. There were 280 cases of perinatal death and overall perinatal mortality rate was 144.1 per 1000 deliveries. There was a significant decrease in the rate from 243.2/1000 in 1953-1962 to 141.5/1000 in 1963-1972, but the rate has risen steadily since 1983. CONCLUSIONS: With the improvement in antenatal care and management of eclampsia, the incidence of eclampsia and its associated maternal mortality has decreased over the last 46 years. But eclampsia still remains a significant complication of pregnancy with high maternal and perinatal mortality.
