Anisakiasis is a parasitic disease of the gastrointestinal tract caused by ingestion Of raw or undercooked fish containing the marine nematode larvae belong to the subfamily Anisakinae. The adult worms are intestinal parasites of marine mammals. Eggs are passed in the feces of these mammals and develop to the second stage larvae in the sea water. They are eaten by crustaceans in which the larvae develop to the third stage. When fish or squid eat the infected crustaceans the larvae migrate to the body cavity or the muscle. The infected fish or squid is eaten by marine mammals the larvae attach to the wall of the stomach and then undergo adult worm. In Korea, human anisakiasis is not rare. The clinical manifestations are variable and depend on the involving site of gastrointestinal tract. The frequent sites are stomach and small intestine, and large intestine is rarely involved. Recently we experienced two cases of ileal anisakiasis occurred in 54-year-old female and 46-year-old female patients. The symptoms were upper and lower abdominal pain, nausea, and vomiting. The resected ileums in case I and 2 measured 12.5 x 2.5 cm and 15.0 x 2.0 cm, respectively. The mucosa and submucosa were thickened. In case 1, submucosal penetration of a white thread-like parasite was seen. The ileum showed submucosal edema, and extensive infiltration of eosinophils, neutrophils, lymphocytes, histiocytes, and plasma cells from mucosa to mesentery with or without mucosal ulceration. The Anisakis larvae are found in the submucosa and propria muscle. They have thick multilayered smooth cuticle, many somatic muscle cells, triradiated esophagus with numerous tall columnar cells, renette cell, and Y-shaped lateral chords. Reproductive organ is absent. In Korea, the previously reported 14 cases and present 2 cases of the intestinal anisakiasis mainly involved ileum, but the cause was not mentioned.

Carcinosarcoma of the esophagus is a rare neoplasm composed of both carcinoma and spindle sarcomatous area. Usually the carcinoma component is a squamous cell carcinoma but rarely adenocarcinoma or undifferentiated carcinoma is found. The histogenesis of the sarcomatous component is still unknown. A case of ulcerated polypoid lesion with a stalk in esophagus was reported. Microscopically it was composed of spindle shaped cells interminled with squamous cell carcinoma and small cell carcinoma nests. No distinct transition between spindle shaped cells and carcinoma are was observed. Immunoreactivity to cytokeratin was observed in both carcinomatous and spindle cell component, but electron microscopic examination failed to demonstrated desmosome or tonofilaments in spindle cells. Undifferentiated small cell nests were reactive to neuron specific enolase and contained membrane bounded secretory granule in electron microscopy.

The secretary meningioma is a distinct variant of meningioma that revealed characteristic light microscopic, immunohistochemical and ultrastructural features of epithelial and secretary differentiation, which was named as a distinct subtype of meningioma by Alguacil-Garcia et al in 1986. We experienced 2 cases of secretary meningioma. One was a 53-year-old female who had suffered from sudden onset of dizziness for I day. The computerized tomography revealed a sharply marginated well enhanced mass in temporal lobe. The other was a 59-year-old female who had suffered from dizziness for 8 years. The computerized tomography revealed a well demarcated lobulated mass in petrosal ridge. In both cases, multiple hyaline inclusions were scattered in the background of meningothelial meningioma. They were PAS positive, diastase resistant, stained yellow with van Gieson, and did not stain with reticulin in contrast to Psammoma bodies. The immunohistochemistry revealed positive reaction for EMA, CEA, a-FP and cytokeratin. T'he electron microscopic study revealed interdigitation with desmosomes and abundant intracellular lumina. They were lined by numerous microvilli and filled with granular material which was composed of electron dense homogenous material, me branous material, and small membrane-bound vesicles. Microvilli were filled with electron dense material identical to the material in the lumina, and some of them were interconnected with electron dense material in the lumina. It was concluded that secretary activity of the meningothelial cells and degenerated microvilli were involved in the pathogenesis of hyaline inclusions.

This study was conducted to assess the prognostic value of tumor angiogenesis and Cathepsin-D in breast carcinoma, by correlating them with other clinicopathologic prognostic factors. In order to estimate microvessels within the tumor, an immunohistochemical method using monoclonal antibodies for factor VIII-related antigens (DAKO-vWf, F8/86) was used, and they were counted (perx200 field) in the most active areas of neovascularization. For the expression of Cathepsin-D, an immunohistochemical method using monoclonal antibodies (Novocastra, NCL-CDm) was performed. The microvessel count ranged from 8 to 346 per x200 field and the mean (+/-SD) was 72.46+/-54.96. The microvessel count was correlated with the estrogen receptor status, and it was also correlated with the tumor size when it was graded into four groups (1-33, 34-67, 68-100, >100), but was not correlated with other clinicopathologic parameters. Cathepsin-D was expressed in 40% (46/115) of the cases, but it was statistically correlated with the tumor size only. In conclusion, the expression of Cathepsin D and the degree of angiogenesis in breast cancer showed a correlation with the tumor size only. Therefore, they do not appear to be good prognostic parameters, according to the present study.

Invasive micropapillary carcinoma is a recently defined unusual variant of invasive breast carcinoma characterized by the formation of micropapillae within clear spaces separated by delicate fibrocollagenous stroma. This study was designed to examine clinicopathologic features of invasive micropapillary carcinoma of the breast. Sixteen cases of invasive micropapillary carcinoma were retrieved from the files of the Department of Pathology, Yeungnam University College of Medicine. We evaluated their clinicopathologic findings including patients' age, tumor size, nuclear grade, vascular invasion, axillary lymph node status, presence of extensive intraductal carcinoma, estrogen and progesterone receptors, p53, c-erbB-2, MIB-1 labelling index and follow-up data and compared this results with those of 292 cases of invasive ductal carcinoma, not otherwise specified. The incidence of invasive micropapillary carcinoma was 4.2% of all invasive breast carcinoma, and the mean age of the patients was 46 years. Nine cases were pure form (over 75% of micropapillary growth pattern in the tumor) and seven cases were mixed form. The results of clinicopathologic findings, except vascular invasion and axillary lymph node status, of the 16 cases of invasive micropapillary carcinoma were not different from those of the 292 cases of invasive ductal carcinoma, not otherwise specified (p>0.05). However, the rate of vascular invasion and axillary lymph node metastasis was significantly higher in invasive micropapillary carcinoma (p <0.05). Of 16 cases, five cases had distant metastasis during follow-up period, and one patient died of cancer. Although the mechanism of higher vascular invasion and lymph node metastasis in micropapillary growth pattern could not be determined, we propose that invasive micropapillary carcinoma should be recognized as a separate entity with increased risks of vascular invasion and axillary lymph node metastsis.

PURPOSE: The aim of this study was to develop a substantive theory on self-management conducted by the adolescents with chronic kidney disease from their lived experience. METHODS: Data was collected through in-depth interviews from May to December in 2015 with thirteen adolescents with chronic kidney disease. The data collected were analyzed on the basis of Strauss and Corbin's grounded theory. RESULTS: The core of the category found in this study was “overcoming the unstable sense of self-control and integrating disease experience into their life”. The causal conditions triggering the central phenomenon were “restriction in daily life” and “manifestation and aggravation of symptom”. The central phenomenon in the experience of self-management within the adolescents with chronic kidney disease was “unstable sense of self control”. The intervening condition for unstable self control were “micro system support” and “motivational resources”. This study found that the adolescents with chronic kidney disease followed a series of strategies when they faced the central phenomenon, including; passive coping, reappraisal of illness, active coping, compliance with treatment, controlling physical activity, and adjusting school life. With these strategic approaches, the adolescents with chronic kidney disease could maintain their active lifestyles and achieve their health behaviors. The process of self-management by these adolescents passed through four phases; limited experience caused by diseases, effort for normalization, reorganizing their daily lives, and integration with daily lives and self-management. CONCLUSION: This Study explored the process and experience of self-management of adolescents with chronic kidney disease. These findings can be used for basis for developing substantive theory and nursing intervention strategy for adolescents with chronic kidney diseases.

PURPOSE: This study was performed to investigate the effects of job embeddedness and nursing professionalism on intent to stay in hospital nurses. METHODS: The study was a cross-sectional survey. Participants were 242 nurses working at four general hospitals in P city of Gyeongbuk Province, Korea. Data were collected from August 29 to September 10, 2016. Structured questionnaires were used and analyzed with the SPSS/PC program. RESULTS: The scores were, for job embeddedness, 3.19 (out of 5.0), nursing professionalism, 3.50 (out of 5.0), and intent to stay, 5.30 (out of 8.0). The three variables were all different according to participants' general characteristics. Factors influencing intent to stay were organization fitness (one of 4 sub-factors of job embeddedness), social recognition (one of 5 sub-factors of nursing professionalism) and age (one of participants' general characteristics). These three variables explained 34% of intent to stay. CONCLUSION: To increase competent career nurses' intent to stay, nursing and hospital managers must develop and implement programs that help improve nurses' organization fitness to adjust well in their organization and healthcare institutions and nursing organizations must continue efforts to raise social recognition of nurses and to improve nurses' working conditions.

This experiment is designed to find differentially expressed genes in p388D1 cells that are specific for the serum deprived state. Serum starvation induces cells to enter the quiscent state in the cell cycle and is used to arrest cell growth or synchronize the cell cycle. Differential display and ribonuclease protection assay were used to identify quantitative change in gene expression. Nineteen genes that showed a differential expression in the differential display were cloned and 7 clones were verified by a ribonuclease protection assay. Among the 7 clones clone-16 showed same expression pattern in comparison with the differential display. Deduced amino acid sequences of clone-16 had N-glycosylation motif and seems to be a secretory protein. Getting a full sequence of clone-16 is critical for the characterization of it.
