PURPOSE: The purpose of this study was to identify the association between safety care activity and documentation of nursing records among nurses working in hospitals and to provide basic data for developing hospital policy for the documentation of nursing records.METHOD: By using a self-reported questionnaire, data were collected from 212 nurses working in six general hospitals in Jeju province from November 2015. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression with the SAS WIN 9.2 program.RESULTS: Safety care activity was positively correlated with the documentation of nursing records (r=.83, p < .001). The documentation of nursing records was significantly predicted by safety care activity, working department, and nursing delivery system, and 70.9% of the variance in the documentation of nursing records was explained (F=172.31, p < .001).CONCLUSION: In this study, safety care activity was the most influencing factor for the documentation of nursing records. Improving work circumstances and building a system are required for nurses' safety care activity to lead to good documentation of nursing records.

PURPOSE: The aim of this study was to identify the factors influencing nursing performance in caring for patients with delirium.METHODS: This study included 166 nurses who worked for more than 6 months at 4 general hospitals in Jeju Province, South Korea. Patients were administered a self-reported questionnaire. The study was carried out from May 20, 2014, to June 19, 2014. Data analyses were conducted using stepwise multiple regression, Pearson's correlation coefficients, t-test, and analysis of variance using the SAS WIN 9.2 program (SAS Institute, Cary, NC, USA).RESULTS: The factors associated with nurses' performance in delirium care were work position (β=.22, t=2.58, p < .001) and having received education on delirium care (β=.16, t=2.24, p=.026).CONCLUSION: The results showed that the nurses' work position and having received education on delirium care affected nursing performance in delirium care. In order to improve nurses' performance in delirium care, hospitals should provide a delirium education program for nurses and establish standard guidelines on delirium care.

Hepatoid thymic carcinoma is an extremely rare subtype of primary thymus tumor resembling “pure” hepatoid adenocarcinomas with hepatocyte paraffin 1 (Hep-Par-1) expression. A 53-year-old man presented with voice change and a neck mass. Multiple masses involving the thyroid, cervical and mediastinal lymph nodes, and lung were detected on computed tomography. Papillary thyroid carcinoma was confirmed by biopsy, and the patient underwent neoadjuvant chemoradiation therapy. However, the anterior mediastinal mass was enlarged after the treatment whereas the multiple masses in the thyroid and neck decreased in size. Microscopically, polygonal tumor cells formed solid sheets or trabeculae resembling hepatocytes and infiltrated remnant thymus. The tumor cells showed immunopositivity for cytokeratin 7, cytokeratin 19, and Hep-Par-1 and negativity for α-fetoprotein. Possibilities of germ cell tumor, squamous cell carcinoma, and metastasis of thyroid papillary carcinoma were excluded by immunohistochemistry. This report on the new subtype of thymic carcinoma is the third in English literature thus far.

We described the clinical manifestation of herpes zoster in thirteen children with underlying malignancies. Among the associated malignancies, hematologic malignancy including acute lymphotytic leukemia was the commonest and CNS tumors were also frequently associated. Pain was mild, and some showed high fever and abnormal liver function test results. Recurrent attacks were observed in 3 cases(23%). Thoracic segment and trigeminal nerve were commonly affected. In most cases, herpes zoster developed within two years after the diagnosis of the malignancy.

BACKGROUND: Coronary angioplasty has been replacing coronary artery bypass grafting (CABG) because of the relative advantage in terms of recovery time and noninvasiveness of the procedure. Compared to other Organization for Economic Cooperation and Development (OECD) countries, Korea has experienced a rapid increase in coronary angioplasty volumes. METHODS: We analyzed changes in procedure volumes of CABG and of percutaneous coronary intervention (PCI) from three sources: the OECD Health Data, the National Health Insurance Service (NHIS) surgery statistics, and the National Health Insurance claims data. RESULTS: We found the ratio of procedure volume of PCI to that of CABG per 100,000 population was 19.12 in 2014, which was more than triple the OECD average of 5.92 for the same year. According to data from NHIS statistics, this ratio was an increase from 11.4 to 19.3 between 2006 and 2013. CONCLUSION: We found that Korea has a higher ratio of total procedure volumes of PCI with respect to CABG and also a more rapid increase of volumes of PCI than other countries. Prospective studies are required to determine whether this increase in absolute volumes of PCI is a natural response to a real medical need or representative of medical overuse.

BACKGROUND: The purpose of this study is to evaluate the concentration of cardiovascular surgical procedures in a metropolitan area and investigate the perception of specialists regarding governmental policies to resolve this imbalance. METHODS: From March to May 2015, surveys were distributed to members of the Thoracic and Cardiovascular Surgery Association. The final pool of research subjects consisted of 75 respondents. Subjects were queried regarding the concentration of cardiovascular operations in metropolitan areas, alternatives to the imbalance, and governmental policies to resolve the inequalities. RESULTS: Survey participants responded that South Korea needs governmental policies to alleviate the concentration of cardiovascular surgery patients in large metropolitan hospitals. Participants agreed that the freedom to choose medical institutions and improved accessibility to metropolitan hospitals due to advanced transportation systems were some of the causes for the concentration. A majority (98.7%) of respondents thought establishing thoracic and cardiovascular surgery centers in provinces was an appropriate solution to alleviate the concentration. Thoracic and cardiovascular surgery specialists were ranked as the number one group on which to focus development. CONCLUSION: Developing and carrying out policies to establish thoracic and cardiovascular surgery centers in provinces will alleviate the regional imbalance in available heart surgery services and an overall improvement in cardiovascular disease treatment in South Korea.

Bisphosphonates have been approved for Paget's disease, cancer - related hypercalcemia, bone involvement in multiple myeloma or solid tumors and osteoporosis. Although, underlying pathophysiological mechanisms remain unclear, it seems that bisphosphonates inhibit osteoclast precursor cells, modulate migratory and adhesive characteristics and induce apoptosis of osteoclasts. Furthermore impacts on angiogenesis, microenvironment and signal transduction between osteoclasts and osteoblasts. In this report, we present a case of oral bisphosphonates induced osteonecrosis of the mandible in a 84-year-old patient who received for two years. Two tapered screw vent implants(Zimmer, USA) were placed in the area of first and second molar. Two weeks later after crowns restored, some inflammatory signs and symptoms were observed on the second molar area. Sequestrum was formed and the sequestrum was removed with the implant. Frequent follow-up checks and oral hygiene maintenances were done and the first molar implant was restored. There is insufficient evidence suggests that duration of oral bisphosphonate therapy correlates with the development and severity of osteonecrosis. Therefore, dentists should not overlook the possibility of development of bisphosphonate induced osteonecrosis in patients who have taken oral forms of medication for less than three years.
