Purpose: This descriptive study investigated the effects of nurses’ knowledge of withdrawalof life-sustaining treatment, death anxiety, and perceptions of hospice care on their attitudes toward withdrawal of life-sustaining treatment. Methods: Data were collected from 262 nurses at tertiary hospitals, general hospitals, or primary hospitals in Busan, Korea, and statistically analyzed using the t-test, analysis of variance, the Scheffé test, Pearson correlation coefficients, and hierarchical regression analysis. Results: The participants’ scores were 3.68±0.45 (out of 5) for attitudes toward withdrawal of life-sustaining treatment, 0.65± 0.15 (out of 1) for knowledge of withdrawal of life-sustaining treatment, 2.61±0.26 (out of 4) for death anxiety, and 4.06±0.43 (out of 5) for perceptions of hospice care. Furthermore, knowledge of withdrawal of life-sustaining treatment and perceptions of hospice care showed positive correlations with attitudes toward withdrawal of life-sustaining treatment, while death anxiety showed a negative correlation. The most significant factors influencing attitudes toward withdrawal of life-sustaining treatment were perceptions of hospice care, followed by having experienced caring for patients who withdrew life-sustaining treatment, death anxiety, having a spouse, and ethical values, and the overall explanatory power was 43.0%. Conclusion This study showed that perceptions of hospice were an important fac-tor influencing nurses’ attitudes toward withdrawal of life-sustaining treatment. Therefore,it is necessary to develop and validate educational intervention programs that can improve perceptions of hospice care.

This case report describes a severe nerve injury to the right ulnar nerve, caused by bee venom acupuncture. A 52-year-old right-handed man received bee venom acupuncture on the medial side of his right elbow and forearm, at a Traditional Korean Medicine (TKM) clinic. Immediately after acupuncture, the patient experienced pain and swelling on the right elbow. There was further development of weakness of the right little finger, and sensory changes on the ulnar dermatome of the right hand. The patient visited our clinic 7 days after acupuncture. Electrodiagnostic studies 2 weeks after the acupuncture showed ulnar nerve damage. The patient underwent steroid pulse and rehabilitation treatments. However, his condition did not improve completely, even 4 months after acupuncture.

The Q-switched lasers which was introduced under the concept of selective photothermolysis. Q-switched Nd:YAG laser, which targets dark pigments in a longer wave length (1064 nm) that has less absorption by melanin, can effectively treat deep tattoos with less pigmentary alterations. We report our experience over the past 3 years in treating 565 patients with tattoos and cutaneous pigmented lesions using the Q-switched Nd:YAG laser. Patients were exposed with a pulse duration of 10 ns and fluences of 6, 7 J/cm2(1064 nm) or 12, 14 J/cm2(532 nm), in exposure spots of 2 mm or 3 mm, at intervals of 4 weeks. Q-switched Nd:YAG laser was effective in removing deep pigmented lesion with 1064 nm, and colored inks with 532 nm. Seventy-three percent of amateur black pigmented lesion were > 75% clear after four to ten treatment. Ninty-eight percent of professional black pigmented lesion were > 75% clear after two on eyebrow, six to eight on extremity and trunk. No significant side effects, including pigmentary changes or scarring, were noted.

PURPOSE:Cardiovascular disease is the predominant cause of death in patients with end stage renal disease. Approximately 33.7% of overall mortality is due to cardiovascular disease, and about 27% of these cardiovascular deaths are attributed to acute myocardial infarction (AMI). Despite the significance of AMI, there are little data on the clinical characteristics of AMI in dialysis patients. METHODS:Thirty-two dialysis patients admitted for AMI from January 2004 to December 2007 were retrospectively analyzed. One hundred twenty-three AMI patients were included as a control. The clinical and laboratory findings of AMI were compared between dialysis patients and non-dialysis patients. RESULTS:The frequency of typical chest pain was significantly lower in dialysis patients than in non- dialysis patients (18.8% vs. 62.6%, p<0.001), and typical ECG findings of STEMI were significantly less noted (28.1% vs. 82.9%, p<0.001). Increases in CPK, CK-MB, and troponin T levels were significantly lower in dialysis patients than in non-dialysis patients ( p<0.001). In contrast, dialysis patients revealed more multi-vessel diseases on coronary angiography and more left ventricular hypertrophy and were associated with higher mortality during admission than non-dialysis patients. CONCLUSION:Although dialysis patients with AMI had less typical chest pain and typical ECG findings, and had lower increases in cardiac enzyme levels, they revealed more severe coronary vessel diseases than non-dialysis patients. Therefore, efforts for early and accurate diagnosis of AMI are needed in dialysis patients with nonspecific complaints of AMI.

OBJECTIVE: To investigate the global functional reorganization of the brain following spinal cord injury with graph theory based approach by creating whole brain functional connectivity networks from resting state-functional magnetic resonance imaging (rs-fMRI), characterizing the reorganization of these networks using graph theoretical metrics and to compare these metrics between patients with spinal cord injury (SCI) and age-matched controls. METHODS: Twenty patients with incomplete cervical SCI (14 males, 6 females; age, 55+/-14.1 years) and 20 healthy subjects (10 males, 10 females; age, 52.9+/-13.6 years) participated in this study. To analyze the characteristics of the whole brain network constructed with functional connectivity using rs-fMRI, graph theoretical measures were calculated including clustering coefficient, characteristic path length, global efficiency and small-worldness. RESULTS: Clustering coefficient, global efficiency and small-worldness did not show any difference between controls and SCIs in all density ranges. The normalized characteristic path length to random network was higher in SCI patients than in controls and reached statistical significance at 12%-13% of density (p<0.05, uncorrected). CONCLUSION: The graph theoretical approach in brain functional connectivity might be helpful to reveal the information processing after SCI. These findings imply that patients with SCI can build on preserved competent brain control. Further analyses, such as topological rearrangement and hub region identification, will be needed for better understanding of neuroplasticity in patients with SCI.

PURPOSE: The objective of this study was to provide current estimates of the prevalence and examine trends of overweight and obesity in children and adolescents. METHODS: Height and weight measurements from 183,159 (112,974 in 1997, 70,185 in 2005) children and adolescents aged 2 to 18 years were obtained via the 1997 and 2005 National Growth Survey. Obesity among children and adolescents was defined as being at or above the 95th percentile of the gender-specific body mass index (BMI) for age in the 2007 Korean National Growth Charts or a BMI of 25 or higher; overweight was defined as being at or above the 85th percentile to less than the 95th percentile BMI. RESULTS: In 2005, 9.7% (11.3% for boys, 8.0% for girls) of South Korean children and adolescents were obese; 19.0% (19.7% for boys, 18.2% for girls) were overweight or obese. The overall prevalence of obesity increased from 5.8% in 1997 to 9.7% in 2005 (from 6.1% in 1997 to 11.3% in 2005 for boys and from 5.5% in 1997 to 8.0% in 2005 for girls); the increasing trend was most evident in boys, especially those aged 13-18 years. CONCLUSION: The prevalence of obesity among children and adolescents increased significantly during the eight-year period from 1997 to 2005. This study suggests that we need to make a priority of developing strategies to control obesity in children and adolescents; the potential health effects of increases in obesity are of considerable public health importance.

Infliximab, a TNF-alpha antagonist, has been used to treat refractory rheumatoid arthritis, ankylosing spondylitis, Crohn's disease and Behcet's disease. Tuberculosis (TB) is a well-known opportunistic infection in patients receiving infliximab. Therefore, patients should be screened and treated for latent or active TB infection before being administered infliximab. Recently, we encountered a case of military TB during infliximab therapy in a patient suffering from Behcet's disease and uveitis. We report this case with a review of the relevant literature.

We aimed to determine the maternal characteristics (demographics, an obstetric history, and prior cervical excisional procedure) associated with a short mid-trimester cervical length (CL, defined as a CL of ≤ 25 mm) and whether having a short cervix explains the association between these maternal characteristics and spontaneous preterm delivery (SPTD, defined as a delivery before 34 weeks). This is a single-center retrospective cohort study of 3,296 consecutive women with a singleton pregnancy who underwent routine CL measurement between 20 and 24 weeks. Data were collected on maternal age, weight, height, parity, obstetric history (nulliparity; a history of at least 1 SPTD; and at least 1 term birth and no preterm birth [low-risk history group]), and prior cervical excisional procedure. In the multivariate regression analysis, an obstetric history, prior cervical excisional procedure, and gestational age at measurement were the variables significantly associated with short CL. In contrast, maternal weight, height, age, and parity were not significantly associated with short CL. By using the likelihood of SPTD as an outcome variable, logistic regression indicated that short CL and obstetric history, but not prior cervical excisional procedure, were significantly associated with SPTD after adjustment for potential confounders. A history of SPTD and prior cervical excisional procedure were associated with an increased risk of a short mid-trimester CL. A history of SPTD, but not prior cervical excisional procedure, is associated with an increased risk of SPTD, independent of a short CL.
