PURPOSE: This study was to investigate patient safety perception and patient participation, and to provide basic data for the development of patient participation education programs.METHODS: The subjects of this study were 183 patients with at least one experience of the Hemato-oncology Department at a tertiary hospital in Seoul. Data were collected from April 11, 2019 to May 7, 2019 using structured questionnaires including patient safety perception and patient participation.RESULTS: The patient safety perception score was 4.23±0.48 out of 5. The patient participation score was 4.30±0.53 out of 5. Patient safety perception was significantly different according to age (p=.008), education (p=.045), employment status (p=.031), marital state (p=.037), medical department (p=.004), comorbidity (p=.046), and patient participation education (p=.010). Patient participation was significantly difference in age (p=.020), education (p=.004) and employment status (p=.005). The correlation between the patient safety perception and patient participation was statistically significant (r=.75, p < .001).CONCLUSION: It is necessary to improve the system for medical staff, patients and medical institutions in order to enable patients to communicate with medical staff in a satisfactory manner and participate in patient safety activities.

Cerebral air embolism (CAE) is a rare complication of various medical procedures. It manifests with symptoms similar to those of typical acute cerebral infarction, however the treatment is quite different. We present a case of arterial CAE that was associated with a disconnected central venous catheter and appeared as punctate dark signal intensities with aliasing artifacts on the susceptibility-weighted filtered phase magnetic resonance image. The susceptibility-weighted filtered phase image can be helpful for diagnosing CAE and the magnetic resonance imaging reflects the pathophysiology of CAE.

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.

PURPOSE: The goal of this study was to evaluate the impact of life style characteristics on the prevalence risk of metabolic syndrome (MS). METHODS: A total of 581 adults were recruited from a cardiovascular outpatient clinic. A newly developed comprehensive life style evaluation tool for MS patients was used, and patient data related to the MS diagnosis were reviewed from the hospital records. RESULTS: The overall prevalence of MS was 53.2%, and the mean of MS score was 2.6 for patients at a cardiovascular outpatient clinic (78% of the patients had hypertension). Dietary habits among the life style characteristics had significant influence on the prevalence risk of MS and MS scores. And also interestingly, the classification and regression tree (CART) model suggested that the high prevalence risk groups for MS were older adults (61.5< or =age<79.4), and adults between 48.5 and 61.5 yr of age with bad dietary habits. CONCLUSION: This study indicates that nurses should focus on dietary habits of patients (especially patients classified as high prevalence risk for MS) for improvement and prevention of MS prevalence risk.

A 20-year-old man developed necrotizing fasciitis of the left chest wall complicating acupuncture. Necrotizing fasciitis is a highly morbid soft tissue infection that rarely involves the upper torso. In the past, there has been few report on necrotizing fasciitis complicating acupunture in the English literature (based on a MEDLINE search covering 1966 to 2005). We present this extremely unusual case of a patient after taking acupuncture who survived severe necrotizing fasciitis of the chest wall following wide debridement of the necrotic tissue and broad-spectrum antibiotic therapy.

PURPOSE: Percutaneous needle aspiration biopsy under the imaging guidance in the diagnosis of intrathoracic diseases has become a standard practice. Core tissue obtained by automated gun biopsy(AGB) is believed to be more diagnostic than materials from fine needle aspiration(FNA) by many cytopathologists. The authors evauated the role of automated gun biopsy in localized pulmonary lesions with respect to the its accuracy and complications. MATERIALS AND METHODS: We performed 107 percutaneous biopsies in localized pulmonary lesions under fluoroscopic guidance among 107 patients:AGB using 18G or 20G was done in 81 patients, and both AGB and FNA was done in 26 patients. RESULTS: Biopsy samples sufficient for histologic diagnosis were obtained in 94(87.9%) of 107 patients, AG8 in 73(90.1%) of 81 patients and AGB and FNA in 21(80.8%) of 26 patients. 11 of 13 negative results were due to inadeguate specimen size for the histologic diagnosis or were composed of necrotic areas, and 2 of 13 negative results were obtained through nontarget tissue. 10 patients developed pneumothorax and 4 of them required chest tube insertion. Minimal hemoptysis was found in 3 patients. CONCLUSION: Percutaneous automated gun biopsy under fluoroscopic guidance was easy and simple method of obtaining specimens of good quality and quantity. It may be an useful procedure in the diagnosis of localized pulmonary lesions.

PURPOSE: MUC1 is a large transmembrane glycoprotein, which is overexpressed in the majority of carcinomas. The high expression of MUC1 is associated with aggressive tumors, with the MUC1 antigen used as a marker to monitor disease progression in breast cancer patients. Although the MUC1 tumor marker is both sensitive and specific for predicting a relapse in breast cancer, it is not commonly used during the follow-up of breast cancer patients. The aim of this study was to evaluate whether the differential patterns of MUC1 expression in different histological types of breast carcinoma could be used to distinguish tumors from benign lesions, and determine its prognostic relevance with other biological parameters. METHODS: 22 normal breast, 7 intraductal hyper-plasia (IDH) and 307 malignant lesions were selected and immunostained with MUC1. The patterns of reaction were classified as intraluminal border (ILB), cytoplasmic, intercellular membrane (ICM), intranuclear or mixed staining. RESULTS: All the normal breast samples showed weak cytoplasmic staining in the ducts and lobules. All the IDH samples showed moderate cytoplasmic and ILB staining. Of the 307 malignant lesions, only 2 (0.8%) showed negative staining; MUC1 positivity was observed in 4 (1.3%), with only ILB staining; 8 (2.6%) with weak cytoplasmic staining, 16 (5.2%) with weak cytoplasmic and intranuclear staining, 168 (54.7%) with moderate cytoplasmic and ILB staining, and 109 (35.5%) with strong cytoplasmic and ICM staining. MUC1 positivity with a moderate to strong staining intensity was observed in 90.6% of the infiltrating ductal carcinomas (221/244), 96.5% of the intraductal carcinomas (28/29), 87.5% of the infiltrating lobular carcinomas (7/8), 66.6% of the mucinous and secretory carcinomas (10/15), 100.0% of the apocrine carcinomas (5/5) and 100.0% of the medullary carcinomas (6/6). The expression of MUC1 was statistically significant between the histological tumor types (p = 0.034), tumor size (p = 0.046), and HER-2/neu (p = 0.004). CONCLUSION: These data suggest the expression of MUC1 was different in normal breast, IDH and malignant breast tumors, and was significantly correlated with the histological tumor types, tumor size and HER-2/neu oncogene.

PURPOSE: This study was conducted to evaluate the relationship of the biological parameters for survival after tumor recurrence or metastases for breast cancer patients. METHODS: Fifty patients with local recurrence or distant metastases after their treatment for breast cancer were selected for our study. RESULTS: These patients constituted 16.9% (50/296) of all the patients with breast cancer who were treated during the investigation period. Survival was correlated with the lymph node status (p = 0.036) and the disease free interval (DFI) (p < 0.001), but patient survival was not correlated with the patient's age (p = 0.586), the tumor type (p = 0.360), tumor grade (p = 0.353), tumor size (p = 0.886), extensive intraductal component (EIC) (p = 0.295), lymphatic invasion (p = 0.880), estrogen receptor (ER) status (p = 0.408), androgen receptor (AR) status (p = 0.386), the HER-2/neu expression (p = 0.291), the operative methods (p = 0.880), adjuvant therapy (p = 0.551) and metastatic organs and recurrence (p = 0.070). The overall median length of the DFI was 25.9 months. The 16 dead patients (32.0%) had a shorter mean DFI (19.7 months) than the mean DFI (28.8 months) of the 34 live patients (68.0%). The overall 5-year survival rate was 10.0%. CONCLUSION: We found the clinicopathological features of the presenting primary tumors that predicted a worse clinical outcome with recurrence or metastases, and these factors can be used in these types of cases as indicators for the prognosis.
