We present a case of mucous gland adenoma arising from the main bronchus of the lower lobe of the left lung in terms of clinicopathologic, immunohistochemical, and ultrastructural aspects as well as review of related literatures. The patient, a 31-year-old female, was admitted to Catholic University Medical College Hospital with complaints of coughing and purulent sputum for about seven years. The chest CT showed a severely calcified tumor in the left lower lobe of the lung. Grossly, the calcified tumor arising from the main bronchus protruded into the lumen and showed bronchiectasis of the lower lobe and atelectasis of the upper lobe of the lung. The tumor was pale brown-gray and sharply circumscribed and showed some small cystic spaces filled with mucoid material. Microscopically, most of the tumor showed dystrophic calcification. The growth pattern of the tumor is composed of cysts, tubules, and glands lined by cytologically bland columnar, cuboidal, or flattened mucus secreting cells. Electron micrograph of tumor cells showed some round or oval mucous granules measuring 0.5-1.8 micrometer.

Cardiac lymphangioma is one of the rarest, primary, benign tumor of the heart. We report a case of cardiac lymphangioma, which was diagnosed with CT and MRI in a 50 years old female. Plain chest film showed minimal enlargement and globular shape of the heart. On CT scan, abnormal fluid density mass lesion was noted within pericardial sac. The signal intensity was lower on T1-weighted image and hgher on T2-weighted image than that of the myocardium and located along the left atrioventricuar groove. Several small low signal spots representing hemorrhage were seen within this lesion.

To elucidate the role of p53 and nm23 in the development, progression, and metastasis of non-small cell lung cancer, we studied 91 paraffin sections of the primary non-small-cell lung cancers and the 34 paraffin sections of their metastatic lymph nodes using the immunohistochemical method. The results are as follows: 1) The incidence of p53 protein expression was positively correlated with the staging of lung cancers (p<0.025). 2) The incidence of p53 protein expression was higher in the lung cancers with lymph node metastasis than in those without lymph node metastasis (p=0.009). 3) The incidence of nm23 protein expression was lower in the adenocacinomas than in the squamous cell carcinomas (p=0.032). 4) The incidence of nm23 protein expression was lower in the lung cancers with lymph node metastasis than in those without lymph node metastasis (p=0.026). The expression of nm23 protein between the primary lung cancers and corresponding metastatic lymph nodes showed positive correlation (Kendall's Tau-b correlation coefficient=0.47140, p=0.0068). 5) The expression of p53 was not correlated with the expression of nm23 protein (Kendall's Tau-b correlation coefficient=0.11387, p=0.2800). The above results suggest that an overexpression of p53 protein and a downregulation of nm23 protein are associated with tumor progression and metastasis in non-small-cell lung cancer.

Primary pulmonary Hodgkin's lymphoma is a rare but distinct entity to be distinguished from nodal Hodgkin's lymphoma and from lymphomas involving lung secondarily. This lymphoma affects women more frequently than men, and typically involves superior portions of the lung. This case is reported to illustrate the clinical, radiographic and anatomic characteristics of the primary pulmonary Hodgkin's lymphoma. A 34-year-old woman presented for the evaluation of hemoptysis. A chest CT revealed a large poorly defined mass in the medial aspect of the right upper lobe, extending to the right mediastinum and trachea. The microscopic examination of the biopsied lesion revealed fibroblastic stroma infiltrated by a mixture of lymphocytes, histiocytes, and eosinophils. The clinical impression was inflammatory pseudotumor, presumably due to slightly favorable response to corticosteroid therapy. Two months later the patient's symptoms worsened despite the steroid therapy and a lobectomy was done. The specimen showed a soft to firm, pale yellow, ill defined mass, 10.0 8.0 cm, involving the visceral pleura. A few satellite nodules around the main mass were noted. The histologic findings were consistent with Hodgkin's lymphoma, nodular sclerosis type.

Sarcomatoid carcinomas are malignant epithelial neoplasms in which the tumor cells assume a partial or complete spindle cell pattern of growth, leading to the erroneous classification of some true carcinomas as sarcomas. These spindle cells are malignant and manifest various amount of both vimentin and cytokeratin. Positive reaction of some of the spindle cells for cytokeratin antibodies is confirmatory. Clinical features do not differ significantly from those of patients with high-grade transitional cell carcinoma. So far, 13 cases of sarcomatoid transitional cell carcinoma of the renal pelvis have been reported in English and Korean literature. In this report, we describe clinicopathologic features of recently observed two cases of sarcomatoid transitional cell carcinoma of the renal pelvis and summarize the pathologic findings of previously reported cases with review of the literature.

PURPOSE: This study has been conducted to identify factors that influence the initiation of treatment after the diagnosis of Korean patients with HIV. METHODS: A cross-sectional study design was used, and 290 patients with HIV from outpatient departments of 7 hospitals participated. Self-report questionnaires included items on the days from the primary diagnosis to the initiation of treatment, and the patients' demographic and disease related characteristics. Negative binomial regression model (NBR) was utilized to determine risk factors influencing the initiation of treatment after the diagnosis of the patients with HIV. RESULTS: The skewness of days was 6.62, and the degree of asymmetry of distribution was severe. In NBR, patients who were in their 40s and 50s, female, unmarried and living with their family, jobless, in a middle or high level of economic status, and diagnosed before 2014 showed a higher risk of delayed treatment than patients who were younger, male, married and living with family, in a low level of economic status, and diagnosed in 2014 or afterwards. CONCLUSION: The findings suggest the necessity of intervention to promote HIV patients' early entry into treatment based on the participants' characteristics.

Purpose: To explore the scope and method of applying standardized nursing terminologies to nursing diagnosis and problems used in nursing practice. Methods: A descriptive study was done with a retrospective analysis of the nursing records of 141,420 patients that were hospitalized in 4 tertiary hospitals. The nursing diagnosis and problems collected from the records were standardized, and the standardized nursing diagnosis and problems cross mapped with NANDA-I, confirmed in a nursing focus group. Results: 65 (67.7%) of the 96 standardized nursing diagnosis and problems were equal with NANDA-I and included in the 10 domains of NANDA-I. Among 86 nursing diagnosis and problems excluded from the cross mapping with NANDA-I, the 63 terms (73.3%) related to surgery/procedure were the most common. Conclusion It is meaningful that multi-tertiary hospital nursing diagnosis and problems were standardized and cross mapping with standard nursing terminologies was performed. As for the method of applying standardized nursing terminologies in nursing practice, it is appropriate to use several standardized nursing terminologies complementarily.

BACKGROUND: The Rheumatoid Factor (RF) is the only serological marker in the diagnosis of rheumatoid arthritis (RA), but its sensitivity and specificity are not satisfactory for the diagnosis of RA. Therefore, we investigated the diagnostic performance of a new anti-cyclic citrullinated peptide antibodies test (anti-CCP) by the enzyme-linked immunosorbent assay (ELISA) in RA. METHODS: A cyclic peptide variant that contains citrulline was used as an antigenic substrate in ELISA. We performed the RF and anti-CCP in 324 RA patients, 251 non-RA patients (rheumatic diseases other than RA), and 286 normal individuals. Diagnostic performances such as sensitivity and specificity were evaluated by the receiver-operator characteristics (ROC) curve at optimal cut-off values. The optimal cut-off values were determined at the maximal point of the area under the curve. RESULTS: The sensitivity and specificity of anti-CCP were 72.8% and 92% at 3.8 U/mL. The sensitivity and specificity of RF were 80.6% and 78.5% at 9 U/mL. The sensitivity and specificity of anti-CCP and RF were 67%, 95.2% and 63.3%, 90% at 8.4 U/mL, 20 U/mL, respectively. A combination of anti-CCP with RF increased the sensitivity and specificity to 79.3%, 96.4%, respectively. Anti-CCP was positive in 23.8% among 63 sero-negative RA patients. CONCLUSIONS: We considered that the anti-CCP might be useful as another new serological marker for the diagnosis of a RA combination with RF, or not, because the anti-CCP has a higher diagnostic specificity than the RF and was an easy, convenient ELISA method in performance.
