PURPOSE: To analyze the clinical features of orbital wall fracture with diplopia between the surgical treatment group and the conservative treatment group. METHODS: The study comprised of 109 eyes of 109 patients with orbital wall fracture and diplopia. The patients were divided into two groups: the surgical treatment group (59 cases) and the conservative treatment group (50 cases). The groups were analyzed retrospectively according to age, gender, cause, CT, the period and severity of diplopia, and enophthalmos with time. RESULTS: In the conservative treatment group, 38 cases (64.4%) had medial wall fracture, and the average fracture size was 26alpha of the inferior wall and 33% of the medial wall. In addition, at the first visit, the patients showed diplopia within 45.5 degrees, and diplopia disappeared completely within 17 days on average (57 cases, 96.6%). In the group that underwent the reconstruction of orbital wall fracture, 27 cases (54.0%) had inferior wall fracture, and the average fracture size was 41% of the inferior wall and 35% of the medial wall. Additionally, in the first visit, the patients showed diplopia within 20.3 degrees. The muscle incarceration occurred in 12 cases (24%). In the surgical treatment group, diplopia disappeared completely within 30 days on average (45 cases, 90.0%). CONCLUSION: In the group of conservative treatment, they showed diplopia within 45.5 degrees at the first visit. Diplopia disappeared completely within 17 days on average (57 cases, 96.6%). In the group of surgical treatment, they showed diplopia within 20.3 degrees at the first visit. Diplopia disappeared completely within 30 days on average (45 cases, 90.0%).

Schilder’s disease is a rare sporadic demyelinating disease of the brain. We report a girl with Schilder’s disease who had undergone Kasai operation for biliary atresia. The patient presented with acute right hemiparesis. Brain magnetic resonance imaging (MRI) showed a single large tumefactive white matter lesion. A diagnosis of Schilder’s disease was based on clinical features and MRI findings. The patient showed dramatic clinical improvement and significant regression of the lesion in response to high-dose intravenous methyl prednisone, and remained free of relapse of other neurologic problems during the 3-year follow-up.

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.

Purpose: This study investigated whether the use of ultrasound (US) guidance in transient elastography (TE) improved the technical success and reliability of liver stiffness (LS) measurements and whether 2-dimensional (2D) shear wave elastography (SWE) provided reliable LS measurements if TE measurements failed. Methods: In this prospective study, 292 participants (male:female, 189:103; median age, 60 years) with chronic liver disease (CLD) were enrolled. LS was measured via the consecutive use of conventional TE, 2D-SWE, and US-guided TE. The technical success rates and reliable LS measurement rates of the three elastography techniques were compared. The risk factors for TE failure were assessed through univariate and multivariate logistic regression models. Results: US-guided TE was associated with a higher technical success rate (281 of 292, 96.2%) and a higher reliable measurement rate (266 of 292, 91.1%) than conventional TE (technical success: 256 of 292, 87.7%; reliable measurements: 231 of 292, 79.1%; P<0.001 for both). In participants for whom conventional TE failed, 2D-SWE provided high rates of technical success (36 of 36, 100%) and reliable measurements (30 of 36, 83.3%). TE failure was associated with female sex (odds ratio [OR], 5.85; 95% confidence interval [CI], 1.30 to 26.40), severe reverberation artifacts (OR, 8.79; 95% CI, 3.93 to 19.69), and high skin-to-liver capsule depth (OR, 1.23; 95% CI, 1.09 to 1.39). Conclusion US guidance in TE improved the technical success and reliable measurement rates in the assessment of LS in patients with CLD. In participants for whom TE failed, subsequent 2D-SWE successfully delivered reliable LS measurements.

Objective: To investigate the diagnostic performance of contrast-enhanced ultrasound (CEUS) and its role as a second-line imaging modality after gadoxetate-enhanced MRI (Gd-EOB-MRI) in the diagnosis of hepatocellular carcinoma (HCC) among at risk observations. Materials and Methods: We prospectively enrolled participants at risk of HCC with treatment-naïve solid hepatic observations (≥ 1 cm) of Liver Imaging Reporting and Data System (LR)-3/4/5/M during surveillance and performed Gd-EOB-MRI. A total of one hundred and three participants with 103 hepatic observations (mean size, 28.2 ± 24.5 mm; HCCs [n = 79], non-HCC malignancies [n = 15], benign [n = 9]; diagnosed by pathology [n = 57], or noninvasive method [n = 46]) were included in this study. The participants underwent CEUS with sulfur hexafluoride. Arterial phase hyperenhancement (APHE) and washout on Gd-EOB-MRI and CEUS were evaluated. The distinctive washout in CEUS was defined as mild washout 60 seconds after contrast injection. The diagnostic ability of Gd-EOB-MRI and of CEUS as a second-line modality for HCC were determined according to the European Association for the Study of the Liver (EASL) and the Korean Liver Cancer Association and National Cancer Center (KLCA-NCC) guidelines. The diagnostic abilities of both imaging modalities were compared using the McNemar’s test. Results: The sensitivity of CEUS (60.8%) was lower than that of Gd-EOB-MRI (72.2%, p = 0.06 by EASL; 86.1%, p < 0.01 by KLCA-NCC); however, the specificity was 100%. By performing CEUS on the inconclusive observations in Gd-EOB-MRI, HCCs without APHE (n = 10) or washout (n = 12) on Gd-EOB-MRI further presented APHE (80.0%, 8/10) or distinctive washout (66.7%, 8/12) on CEUS, and more HCCs were diagnosed than with Gd-EOB-MRI alone (sensitivity: 72.2% vs. 83.5% by EASL, p < 0.01; 86.1% vs. 91.1% by KCLA-NCC, p = 0.04). There were no false-positive cases for HCC on CEUS. Conclusion The addition of CEUS to Gd-EOB-MRI as a second-line diagnostic modality increases the frequency of HCC diagnosis without changing the specificities.

Hepatoblastoma is the most common pediatric liver malignancy and usually occurs within the first 3 years of life. In recent years, the overall incidence of hepatoblastoma has exhibited the greatest increase among all pediatric malignancies worldwide. The diagnosis of hepatoblastoma may be challenging due to the lack of a current consensus classification system. The International Pediatric Liver Tumors Consensus introduced guidelines and a consensus classification for the diagnosis of hepatoblastoma as either epithelial or mixed epithelial and mesenchymal and in the updated 5th edition of the World Health Organization Classification of Digestive System Tumors.

BACKGROUND: The testes are one of the most common extramedullary sites of relapse in boys with acute lymphoblastic leukemia(ALL). The reported incidence of isolated testicular relapse varies from 3 to 40%. If these patients are treated exclusively with testicular irradialion, a systemic relapse occurs within a few months. Recently, the use of intensive chemotherapy and testicular irradiation improved the survival rate for boys with testicular leukemia. So, we performed this study to identify clinical manifestations, disease free survival and prognostic factors of testicular leukemia in children. METHODS: We reviewed 33 patients of testicular leukemia among total 410 boys with ALL diagnosed at the Department of Pediatrics, Seoul National University Children's Hospital from Jan. 1970 to Aug. 1996. Testicular leukemia was confirmed by testicular biopsy in all 33 patients. These patients were treated with combined local testicular irradiation(2,400~2,500 cGy/8~12fractions) and systemic chemotherapy. Two patients, in whom testicular relapse was diagnosed before 1979, unilateral orchiectomy of the involved site and testicular irradiation of the opposite site were performed. Probability estimates of disease free survival (DFS) were calculated by the method of Kaplan and Meier, and the relationship of prognostic factors to DFS was compared using the chi-square test in survival analysis. RESULTS: In 410 boys with ALL, testicular leukemia occurred in 33 patients(8%). Of 33 patients, 6 patients presented with testicular involvement at initial diagnosis, 16 patients had testicular relapse while still receiving chemotherapy and 11 patients had testicular relapse 3 to 57 months(median : 15 months) after cessation of chemotherapy. The median age of 33 patients was 7.4 yrs(9 months~18 yrs) and median WBC count 7,600/ L(2,700~270,000/L). All patients presented with painless testicular enlargement and testicular leukemia was confirmed by testicular biopsy. Among 33 patients, 2 had prior CNS relapse and 11 had concomitant bone marrow and/or CNS relapse. Twenty nine patients were treated with combined local testicular irradiation and systemic chemotherapy. Eleven had second relapse(6 bone marrow, 3 CNS, 2 opposite testis). Seventeen have been followed until now: 6 patients on chemotherapy and 11 patients(37.9%) in complete remission for 48.5+/-22.3 months(19~86 months). The 3 year DFS for 29 patients was 55.3%+/-10.1%. The following prognostic factors showed no significant association with DFS in testicular relapse : age and WBC count at initial diagnosis, age at testicular relapse, and concomitant relapse. Whether testicular relapse occurred on initial therapy or off initial therapy has prognostic value in predicting DFS. The 3 year DFS for boys with testicular relapse on and off initial therapy were 40.0%+/-12.9% and 78.8%+/-13.4%, respectively(P: 0.046). CONCLUSION: With the use of chemotherapy and testicular irradiation, prolonged second re mission can be achieved in many patients with testicular leukemia. The patients with testicular relapse off initial therapy fared significantly better than patients on therapy. So, to improve the DFS for boys with testicular leukemia, a better understanding of its biology and prognostic factors is needed.

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.
