Effects of Nurses' Incident Reporting Attitude, Perception of Importance on Patient Safety Management, and Patient Safety Culture on the Reporting of Patient Safety Events / 간호행정학회지

Purpose@#This study’s purpose is to examine the effects of nurses' incident reporting attitudes, their perceptions of importance of patient safety management, and patient safety culture on reporting patient safety events. @*Methods@#We used a cross-sectional design with a convenience sample of 192 nurses with more than three months clinical experience from five provincial hospitals. The data were collected through an online structured self-report questionnaire from September 25 to October 15, 2022. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. @*Results@#The most important influencing factors for the level of patient safety event reporting were perceptions of the importance of patient safety management (β=.24, p=.005), followed by patient safety culture (β=.23, p=.019), incident reporting attitude (β=.18, p=.016), and near miss reporting experience (β=.14, p=.022). The explanatory power of the model was 33%. @*Conclusion@#To increase the level of patient safety incident reporting, differentiated education and standardized work procedures are needed. Also, it is necessary to prepare policies that revitalize patient safety reporting systems at medical institutions as measures to prevent patient safety accidents and recurrences.

Primary Pulmonary Leiomyosarcoma: Could It Be Cured by Radiation Therapy?

Primary leiomyosarcoma of lung is extremely rare and often diagnosed as a mass on routine chest radiography. Although advances have been made in treatment protocols, leiomyosarcoma remains one of the more difficult soft tissue sarcomas to treat. Surgical resection is usually curative for small and well-differentiated sarcomas. For poorly differentiated and non-resectable tumors, chemotherapy and radiation therapy are used as neoadejuvant or palliative treatment options. Generally, leiomyosarcomas are known to be resistant to radiation therapy alone. The authors experienced a 68-year-old woman who was diagnosed leiomyosarcoma by routine chest radiography. Although disease progression was observed despite of chemotherapy, radiation therapy reduced the size of tumor. This paper describes the curative potential of radiation therapy for primary pulmonary leiomyosarcomas through a case report and literature review.

No Detection of Simian Virus 40 in Malignant Mesothelioma in Korea

BACKGROUND: Simian virus 40 (SV40), a polyomavirus, was discovered as a contaminant of a human polio vaccine in the 1960s. It is known that malignant mesothelioma (MM) is associated with SV40, and that the virus works as a cofactor to the carcinogenetic effects of asbestos. However, the reports about the correlation between SV40 and MM have not been consistent. The purpose of this study is to identify SV40 in MM tissue in Korea through detection of SV40 protein and DNA. METHODS: We analyzed 62 cases of available paraffin-blocks enrolled through the Korean Malignant Mesothelioma Surveillance System and performed immunohistochemistry for SV40 protein and real-time polymerase chain reaction (PCR) for SV40 DNA. RESULTS: Of 62 total cases, 40 had disease involving the pleura (64.5%), and 29 (46.8%) were found to be of the epithelioid subtype. Immunostaining demonstrated that all examined tissues were negative for SV40 protein. Sufficient DNA was extracted for real-time PCR analysis from 36 cases. Quantitative PCR of these samples showed no increase in SV40 transcript compared to the negative controls. CONCLUSIONS: SV40 is not associated with the development of MM in Korea.

A Case of Pulmonary Sarcoidosis with Elevated Carcinoembryonic Antigen (CEA) / 결핵및호흡기질환

Sarcoidosis is a multi-systemic granulomatous disorder of unknown etiology. The characteristic pathological finding is the presence of non-caseating granulomas. The lungs are primarily affected, however other organs may be involved causing various symptoms and ambiguous laboratory findings can be present. There are a few reported cases of sarcoidosis with elevated tumor markers. We describe a 68-year-old woman presenting with sarcoidosis showing elevated serum carcinoembryonic antigen (CEA). The possibility of cancer arising from serum CEA such as gastrointestinal cancer, breast cancer and lung cancer was excluded. A transbronchial lung biopsy demonstrated a non-caseating granuloma without necrosis. As a result prescribed 30 mg prednisolone daily to the patient and serum CEA was decreased after 1 month of treatment. We report a case of pulmonary sarcoidosis with elevated serum CEA.

A Case of Extensive Stage Small Cell Lung Cancer Presenting as an Acute Appendicitis with Perforation / 결핵및호흡기질환

The incidence of appendiceal metastatic cancer is quite low. In particular, in small cell lung cancer, there is a very low incidence of a metastasis to the appendix. A 75-years old man with right lower quadrant pain, cough and sputum was transferred to our hospital. Abdominal CT revealed acute appendicitis with a perforation. The patient underwent surgery. The frozen sections of the tissue obtained during surgery, indicated a malignancy, but a right hemicolectomy was not performed due to the patient's poor general condition. The histology findings of the appendix were identified as a small cell carcinoma. The abdominal CT scan and chest x-ray at admission day showed a mass in the right lower lobe, and a further evaluation of the lesion was performed including positron emission tomography and flexible bronchoscopy with a biopsy. The pathology findings of the lung mass were also small cell lung cancer. The specimens from both sites stained positive for cytokeratin, cluster designation 56, synaptophysin, chromogranin-A and thyroid transcription factor 1. It was concluded that the appendiceal small cell cancer originated from the lung.

A Case of Primary Mucosa-Associated Lymphoid Tissue Lymphoma of the Trachea and Colon / 결핵및호흡기질환

The 64-year-old female patient with cough and intermittent hemoptysis of six months duration visited our hospital. On chest computed tomography, a small, ovoid, 1.3cm sized and well enhanced lesion was detected on the distal trachea. Two multiple lobulated lesions on the sigmoid and transverse colon were revealed on the colonoscopy. The histological findings showed small and medium sized lymphocytes infiltration, CD20 and CD79a positive staining and multiple lymphoepithelial lesions on the distal trachea and colon tissues. Herein, a case of primary MALT lymphoma, with involvement of the trachea and colon, which was treated with rituximab (CD20 anti-monoclonal antibody), cyclophosphamide, adriamycin, vincristine and prednisolone (CHOP regimen), is reported.

Somatostatinoma of the Ampulla of Vater

Somatostatinoma is a rare form of neuroendocrine tumor that was first described in 1977. Most tumors have involved the pancreas, and gastrointestinal tract involvement is rare. Somatostatinomas of the ampulla of Vater are extremely rare and present distinct clinical and pathologic differences. Pancreatic somatostatinoma has been associated with a clinical syndrome of dyspepsia, mild diabetes, cholelithiasis, steatorrhea, and hypochlorhydria, but duodenal somatostatinoma, in general, has been clinically silent. A further contrast is that duodenal carcinoid tumors, mainly gastrinoma, tended to be benign, whereas ampullary carcinoid tumors, mainly somatostatinoma, exhibited malignant behavior. Therefore, definite diagnosis is important for treatment and prognosis, and is performed by image study, immunohistochemistry and electron microscopic examination. We report a case of somatostatinoma of the ampulla of Vater in a 51-year-old male. He complained of generalized abdominal pain for a few days. Gastrofiberscopically, a 1.2 cm sized bulging mass was observed on the ampulla of Vater. Radiologically, on abdomen CT, a protruding enhancing mass was revealed in the duodenum. In octreoscan, there was an abnormal focus off increased radiouptake in the infrahepatic area. He underwent a pancreatoduodenectomy. Grossly, the mass was an intraluminary protruding polypoid submucosal mass with focal ulceration in the ampulla of Vater. Histologically, it showed well-differentiated nonpleomorphic tubular cell nest and psammoma bodies. Immunohistochemically, the tumor cells showed a neuroendocrine nature with synaptophysin immunostain and intense staining only for somatostatin.

A Case of Severe Thyrotoxicosis Induced by Hydatidiform Mole / 대한내분비학회지

Human chorionic gonadotropin (HCG) is one of the glycoproteins families synthesized by the placenta, and consists of 2 noncovalently joined subunits, namely, alpha and beta. The alpha and beta-subunits have a structural homology with the alpha and beta-subunits of TSH and LH. The thyrotropic action of HCG results from its structural similarity to TSH, so beta-HCG can bind to the TSH receptor in the thyroid gland. A high level of HCG, accompanied by an increased thyroid hormone level, can be observed in gestational trophoblastic diseases (GTD), such as a hydatidiform mole or a choriocarcinoma. However, the clinical symptoms of hyperthyroidism in GTD are rarely observed. A 27-years-old woman, admitted due to an amenorrhea of 11 weeks duration, with thyrotoxic symptoms, such as weight loss, palpitation, sweating, tremor, heat intolerance and anxiety, was evaluated. Her serum free T4 level was 8 times higher than normal, and her serum beta-HCG level was over 1,000,000IU/L. She had a curettage operation, with the pathological findings of a complete hydatidiform mole. These thyrotoxic symptoms developed due to a hydatidiform mole, and were accompanied with a highly increased serum beta-HCG level. After evacuation of the molar tissue, the thyroid hormone and thyrotoxic symptoms normalized. Here, this case is reported, with brief review of the literature.

Metastatic Malignant Fibrous Histiocytoma in Lung: One Case Report / 대한흉부외과학회지

At OPD follow-up in December 1998, chest x-ray of a 42-year-old female showed a solit ary pulmonary nodule at a superior basal segment in the right lower lobe. After percut aneous transthoracic needle aspiration failure, wedge resection of the superior basal segment of lower lobe in right lung was performed for diagnosis and therapy. Three years ago, she had received surgery to remove a mass in the left buttock. The mass was pathologically diagnosed as malignant fibrous histiocytoma. She subsequently received 4500 rad radiotherapy for 35 days. Pathology confirmed metastatic malignant fibrous histiocytoma of the lung.

A Case of Inflammatory Fibroid Polyp of the Stomach / 대한소화기내시경학회지

Inflammatory fibroid polyp is a relatively rare, benign polyp which is composed of fibraus connective tissue, blood vessels, and infiltration of eosinophils. The majority of inflammatory fibroid polyps has been reported with pathologic specimen in stomach and small intestine. We performed the gastrofiberscopy and endoscopic ultrasonogram of an inflammatory fibroid polyp, which reveals central ulcerated polypoid mass originated in the submucosa of antral portion of the stomach. So we report a case of endoscopic and endoscopic ultrasonographic findings of inflammatory fibroid piolyp in stomach. The etiolagy and pathology are discussed with the review of the literatures.
