Purpose: The purpose of this study was to apply patient-engaged bedside handoffs in comprehensive care units, and to evaluate the effects of bedsides to nurses and patients. Methods: This study employed a cluster randomized cross-over design.Electrical Medical Record (EMR)-based handoffs and patient-engaged bedside handoffs were alternatively applied to 104 patients, who were assigned to a total of 30 clusters (nursing handoff teams) in 4 comprehensive care units at the S medical center in Seoul, and the patients evaluated each type of handoffs. A total of 139 nurses were also participated in the same units and evaluated each type of handoffs. Data were analyzed using t-test, Wilcoxon rank sum test, ANOVA, and Kruskal-Walls test. Results: The patient's satisfaction of the patient-engaged bedside handoffs was higher than that of the EMR-based handoffs (Z=-5.16, p<.001). On the other hand, the nurse's satisfaction of the patient-engaged bedside handoffs was significantly lower than that of the EMR-based handoffs (t=13.21, p<.001). There were no differences in length of the reporting time between two types of handoffs (t=-0.48, p=.634). Conclusion Patient satisfaction with the patient-engaged bedside handoffs was higher than that of EMR-based handoffs, and nurses' satisfaction with the patient-engaged bedside handoffs was significantly lower than that of EMR-based handoffs. Future studies are needed regarding the impacts of patient-engaged bedside handoffs on the quality of healthcare by identifying the benefits of the handoffs.

PURPOSE: The purpose of this study was to provide basic evidence to improve community health nursing practice education by analyzing the current status of actual operation, program outcomes and evaluation methods, and the level of achieving learning goals. METHODS: Data were collected through an e-mail survey from 155 professors teaching community health nursing in April 2016. Out of 45 responses in total, 42 cases were used for analysis (response rate 29.0%). RESULTS: Community health nursing practice was a 3-credit course in most of the schools (66.7%) and included a practice at public health centers without exception. The most common diagnosis classification system was OMAHA (81.0%). The core fundamental nursing skills evaluated during the practice were subcutaneous injection, vital signs, oral administration, and intradermal injection. Among the subjects of community health nursing practice, the area with the highest potential for achieving learning goals was primary health care provision (4.4/5) and the area with the lowest potential was disaster management (2.4/5). CONCLUSION: The results of this study show that there would be active efforts to complement and improve several problems of the community health nursing practice among the community health nursing practice instructors for more effective and qualitative community health nursing practice.

Human adenovirus type 5 (hAd5) vectors have been demonstrated to be useful vehicles for gene expressions in animals. However, it has not been reported whether hAd5 transduction might be hampered in the sera of livestock animals in Republic of Korea. We collected 205 samples of livestock animals, such as pig (n=84), cattle (n=84), and goat (n=37) in Korea. The neutralizing antibody (NAb) titers to hAd5 virus were less than 15 in most of samples. Only 8% of goat samples had a NAb titer of 15 or 30. Thus, we showed that hAd5 virus was not neutralized in sera from cattle, pig, and goat, and suggest that the hAd5 vector could be used for the effective delivery of vaccines or proteins in livestock animals in the field.

OBJECTIVES: The purpose of this study was to assess the microbiological quality of unchlorinated drinking water in Korea, 2010. One hundred and eighty unchlorinated drinking water samples were collected from various sites in Seoul and Gyeonggi province. METHODS: To investigate bacterial presence, the pour plate method was used with cultures grown on selective media for total bacteria, total coliforms, and Staphylococcus spp., respectively. RESULTS: In the 180 total bacteria investigation, 72 samples from Seoul and 33 samples from Gyeonggi province were of an unacceptable quality (>10(2) CFU/mL). Of all the samples tested, total coliforms were detected in 28 samples (15.6%) and Staphylococcus spp. in 12 samples (6.7%). Most of the coliform isolates exhibited high-level resistance to cefazolin (88.2%), cefonicid (64.7%) and ceftazidime (20.6%). In addition, Staphylococcus spp. isolates exhibited high-level resistance to mupirocin (42%). Species of Pseudomonas, Acinetobacter, Cupriavidus, Hafnia, Rahnella, Serratia, and Yersinia were isolated from the water samples. CONCLUSIONS: The results of this study suggest that consumption of unchlorinated drinking water could represent a notable risk to the health of consumers. As such, there is need for continuous monitoring of these water sources and to establish standards.

Plasma cholesterol is increased in normal aging in both rodents and humans. This is associated with reduced elimination of cholesterol and decreased receptor-mediated clearance of plasma low-density lipoprotein (LDL) cholesterol. The aims of this study were: (1) to determine age-related changes in plasma lipid profiles, and (2) to determine the effect of fenofibrate, an activator of peroxisome proliferator activated receptor alpha (PPAR alpha), on plasma lipid profiles in normal rats on a standard diet. Male Sprague-Dawley (SD) rats (n=15) were fed standard chow and water from 10 to 25 weeks of age. During that period, we measured daily food intake, body weight, fasting and random blood glucose levels, plasma total cholesterol (TC), triglycerides (TG), and free fatty acid (FFA) levels. At 20 weeks of age, all rats were randomly divided into two groups: a fenofibrate group (in which rats were gavaged with 300 mg/kg/day of fenofibrate) and a control group (gavaged with water). Fenofibrate treatment lasted 5 weeks. There were no significant changes in daily food intake, blood glucose, and plasma TG level with age. Body weight, plasma TC, and FFA levels were significantly increased with age. Fenofibrate significantly decreased plasma concentrations of TC and FFA, which had been increased with age. However, fenofibrate did not influence the plasma concentration of TG, which had not increased with age. These results suggest that fenofibrate might have a novel role in preventing age-related hypercholesterolemia in SD rats on a normal diet.

BACKGROUND: Granulocyte stimulating factor (G-CSF) and bone marrow mononuclear cells (BM-MNC) were reported to improve cardiac function after myocardial infarction (MI). This study was to examine their combined beneficial effects and mechanisms of actions in reperfused MI, which have not been verified yet. METHODS:Fifteen pigs were divided into 3 groups after a 1-hour balloon occlusion and reperfusion of the left anterior descending coronary artery. G1 (n=5) was a control, G2 (n=5) was a G-CSF injected group (10 ug/kg/day, from day1 to day7 after MI), and G3 (n=5) was an autologous intracoronary BM-MNC infused group after G-CSF treatment RESULTS:Modified wall motion indices by echocardiography were similar among 3 groups at 24 hours after MI. However, they improved significantly in G2 and G3 at 35days after MI (p<0.05). The percentage of infarct area/left ventricular myocardial area measured from a triphenyltetrazolium chloride (TTC) stain was lower in G3 than in G1 or G2 (p=0.026). The number of vWF-positive vessels and the expressions of vWF and VE cardherin by RT-PCR were higher in G3 and G2 than in G1 (p<0.05). The number of TUNEL-positive cells and bcl2/bax ratio were not significantly different among 3 groups. CONCLUSION: This study suggests that intracoronary BM-MNC infusion with G-CSF treatment in reperfused MI reduced infarct size, improved left ventricular function and prevented ventricular remodeling.

PURPOSE: Computed tomography theoretically should improve detection of foreign bodies and provide more information of adjacent soft tissues. And the CT scanner and PACS program proved to be an excellent instrument for detection and localization of most facial foreign bodies above certain minimum levels of detectability. The severity of injury in penetrating trauma to the face, it is often underestimated by physical examination. Diagnosis of a retained foreign object is always critical. METHODS: From March, 2005 to February 2008 a study was done with 200 patients who had facial trauma. Axial and coronal CT images were obtained with a General Electric(Milwaukee, Wis) 9800 CT scanner at 130kV, 90mA, with a 2-mm section thickness and a 512x512 matrix. RESULTS: Axial and coronal CT images at various window widths should be used as the first imaging modality to detect facial foreign bodies. The attenuation coefficients for the metallic and nonmetallic foreign bodies ranged from -437 to +3071 HU. As a general rule, metallic foreign bodies produced more Hounsfield artifacts than nonmetallic foreign bodies, thus providing a clue to their composition. All of the metallic foreign bodies were represented by a single peak and had a maximum attenuation coefficient of +3071 HU. Of the nonmetallic foreign bodies, glass had an attenuation coefficient that ranged from +105 to +2039, while plastic had a much lower coefficient that ranged from -62 to -35. wood had the lowest range of attenuation coefficients: -491 to -437. CONCLUSION: The PACS program allows one to distinguish metallic from nonmetallic foreign bodies and to individually identify the specific composition of many nonmetallic foreign bodies. This program does not, however, allow identification of the specific composition of a metallic foreign body. We recommend this type of software program for CT scanning of any patient with an injury to the face in which a foreign body is suspected.

Blow-out fracture is frequently encountered in facial bone trauma. And the frequency of medial orbital wall fracture in Asia is high. Various approaches have been reported for medial orbital wall fractures. The field of medial orbital surgery is difficult due to lack of visualization of fracture site, blind dissection of orbital wall, susceptibility of injury of orbital structures. Recently, endoscopic reduction of orbital wall was provided good fuctional and cosmetic results. In order to address this shortcoming we have explored the use of endoscopic external short scar approach in medial orbital wall dissection to allow direct visualization of orbital content and nearly whole fracture components. In this study a direct local approach through a 2cm, modified Z-shaped incision on superior medial orbital area was used as a consistent method to reconstruct medial blow-out fractures. The incision line consist 3 limbs. The angle of the limbs is to 110 degrees. First, 1cm sized line exsists frontonasal line. Second, 5mm sized 2 limbs of the incision line were placed parallel or oblique to the relaxed skin tension line. During the follow-up period of 6 to 12 months, excellent functional and cosmetic results were observed with an inconspicuous scar. Therefore, a direct external short scar incision approach with endoscope on the superior medial orbit may be a consistent method to gain the surgical goal in treatment of blow-out fractures of the medial orbital wall.

Osteomas in the head and neck regions are benign bone neplasms usually found in the frontoethmoid area. Osteomas are usually produce symptoms secondary to pressure on adjacent structures. Although commonly discovered in the external auditory canal of the temporal bone, few cases have been reported in the mastoid or squamous portion of the temporal bone. When located in the mastoid and squamous parts of the temporal bone osteomas can cause cosmetic deformity such as external mass or an auricular protrusion. Other neoplasms of the mastoid region such as osteosarcoma and osteoblastic metastasis should be considered for the differential diagnosis. The authors experienced a case of osteoma that originated from mastoid of temporal bone. We report this rare case and its successful management with a review of the literatures.

The preauricular fistula is a congenital malformation of the ear with a small opening in the preauricular area. In general, this malformation should be treated by excision after its infection is brought under control with antibiotics. For cosmetic consideration, we performed a elliptic incision around opening, and then we dissected along the fistula tract to the cyst without sacrificing too much soft tissues. From March 2001 to March 2005, 90 patients with 102 cases of fistulas were excised including a small portion of auricular perichondrium and cartilage, where they adhered closely. Then, histologic findings of preauricular fistula were studied. The histologic findings reveal that the fistular tract is very close to auricular cartilage, and the thickness of fistular epithelium and perichondrium are about the same. There was no specific complications related to this procedure. The recurrence rate for the excision with cartilage was 2 out of 102(2%). Results of surgery in all cases were satisfactory. It is important, in preauricular fistular excision, perichondrium and auricular cartilage should be excised to prevent recurrence.
