Tumors of umbilical cord, especially angiomyxoma, are extremely rare lesions. To our knowledge, five cases of angiomyxoma have been reported previously in the umbilical cord. Sonography two weeks after the finding of an elevated serum alpha-fetoprotein, detected a mass of the umbilical cord in a 27-year-old multiparous woman at 18(+3) weeks gestation. Previous sonogram was normal (11 weeks gestational age). At 26 weeks, a premature female infant was delivered by induction and a mass was located in the region of placental insertion of the cord. Section through the mass revealed rubbery myxoid appearance. Microcopically, numerous small vascular channels with thin walls were embedded in loose myxoid matrix. A case of angiomyxoma of umbilical cord with elevation of serum alpha-fetoprotein is presented together with a review of the literature. We hope that this case will help define the natural history of primary angiomyxoma of umbilical cord.

PURPOSE: Professional nursing ethics is a living, dynamic set of standards for nurses'professional moral behavior. Furthermore, in daily clinical nursing training, nursing students are constantly confronted with decisionmaking that is moral in nature. The aim of this study was to identify the perceived ethical attitudes in the clinical training process of senior nursing students using Q-methodology to offer basic strategies for nursing ethics education and thereby improve patients'care. METHODS: Q-methodology provides a scientific method for identifying perception structures that exist within certain individuals or groups. Thirty-seven participants in a university rated 38 selected Q-statements on a scale of 1-9. The collected data were analyzed using pc-QUNAL software. RESULTS: Principal component analysis identified 3 types of ethical attitudes in nursing students in Korea. The categories were labeled Sacred-life, Science-realistic and Humane-life. Sacred-life individuals think that a life belongs to an absolute power (God), not a man, and a human life is a high and noble thing. Science-realistic individuals disagreed that allowing an induced abortion or embryo (human) duplication is unethical behavior that provokes a trend, which takes the value of a life lightly; most of them took a utilitarian position with respect to ethical decisions. Humane-life individuals exhibit a tendency toward human-centered thought with respect to ethical attitudes. CONCLUSION: This study will be of interest to educators of students of nursing and hospital nursing administrators. Also, the findings may provide the basis for the development of more appropriate strategies to improve nursing ethics education programs.

Since death is an extremely subjective and unique experience, if we take into account the lack of understanding about death due to the difficulty in methodology, it is very important to try to understand the subjectivity of death. In this respect, Q-methodology that explains and shows the respondents' subjectivity by objectifying his subjectivity is employed as a solution to the questions in this study. Therefore, the purpose of this study was to provide data on how medical personnel should treat their patients, when, it comes to death ; by finding out the opinions of those who are being treated, namely the patients, and those who are providing the treatment, namely the medical personnel. It also by examined the characteristics and relationships between these two groups on attitudes to death. The results of this study show that medical personnel have two(fate-recipient, reality-oriented) types of response and patients have three(religion-dependent, science-adherent, sardonist) types. Medical personnel saw patients as having three(life-attached, traditionalist, death-rejector) types of response and to patients saw medical personnel as having two(rationalist, humanist)types. The relationship between the above-mentioned types will be examined in a coorientation model, the subjectivity of the medical personnel and the patient toward death indicates a relatively high understanding between the two groups under the great proposition of 'death'. Therefore, in their relationship with people who are facing death, the provider of care, namely the medical personnel, should identify the subjectivity of the patient before approaching them. By doing this, they can minimize the conflicts they might experience in establishing a therapeutic relationship, reduce suffering, and help the patient in greeting a more comfortable death. Throughout the study, Q-methodology expands out understanding of coorientation model that has only been approached with R-methodology. This study confirmed Q's potentiality and its validity in human subjective matters.

In order to examine the neurotoxic mechanism of oxygen radicals on cultured bovine oligodendrocytes, cytoxic effect of oxygen radicals was examined when cultures were treated with various concentrations of xanthine oxidase (XO) and hypoxanthine (HX) in culture medium. In addition, the neuroprotective effect of iron-chelators against the neurotoxicity induced by oxygen radicals was evaluated by MTT assay. Cell viability was remarkably decreased in a time-dependent manner after exposure of cultured bovine oligodendrocytes to 20mU/ml XO and 0.1mM HX for 4 hours. In the neuroprotective effect of iron-chelators on oxidant-induced neurotoxicity, tetrakis (2-pyridylmethyl)ethylenediamine (TPEN) blocked the neurotoxicity induced by oxygen radicals, while DFX was not effective in blocking oxidant-induced neurotoxicity in these cultures. These results suggest that oxygen radicals are toxic in cultured bovine oligodendrocytes, and also selective iron-chelators such as TPEN are effective in blocking the neurotoxicity induced by oxygen radicals.

Mutation of p53 gene is one of t.he commonest genetic changes in the development of human cancer including ovary. We intvestigated the diagnostic usefulness of the demonstration of p53 gene immunoreactivity in ovarian cancers, because immunochemical demonstration of p53 immunoreactivity is inexpensive, easily controlled and can be applied in routine pathology laboratories. p53 immunoreactivity was not identified in any patients in whom there was no morphological evidence of neoplasia. ln contrast, in contrast, in 46% of patients of ovarian cancer, p53 immunoreactivity was identified. Overexpression of gene correlated with advanced stage but did not corre1ate with grade, cell type and tumor size.

Sensorineural hearing loss (SNHL) that is seldom cited as a Kawasaki disease (KD) complication is known as an additional, potentially severe, and frequently irreversible sequel. Furthermore the vestibular functions of KD have been underestimated and it could be an important complication combined with SNHL in KD. We described a case that a 4 year-old boy who developed vestibular loss with SNHL has recovered successfully with a combined treatment.

PURPOSE: Despite withdrawal of RotaShield® and the development of second generation live attenuated rotavirus vaccines, concerns remain regarding the relationship between rotavirus vaccine and intussusception. Nevertheless, since there is no study in Korea, we reviewed data from cases at Severance Children's Hospital to determine the association between rotavirus vaccine and intussusception. MATERIALS AND METHODS: Patients coded as intussusception and following a prescription of RotaTeq® from 2007 to 2013 were reviewed. We calculated comparative incidence figures (CIFs) and 95% confidence intervals (CIs) to compare the risk of intussusception in Korea with the risk in the United States. Expected cases within the four-week post-vaccination window were calculated by applying rates of intussusception from data compiled by the Health Insurance Review and Assessment Service (for a five-year period) to numbers of vaccinations. RESULTS: In total, 10530 doses of pentavalent rotavirus vaccine were administered. A total of 65 intussusception cases were diagnosed, although only two cases occurred within four weeks after vaccination. This was compared to six cases within 999123 doses in United States from April 2008 to March 2013 (CIF, 31.63; CI, 31.33–31.93). When we adjusted incidence rate differences for both countries, the CIF decreased to 7.05 (CI, 6.72–7.40). When we compared our identified cases with the expected cases from our hospital, there was no increased intussusception occurring within four weeks of vaccination. CONCLUSION: We found no association between pentavalent rotavirus vaccine and intussusception. Therefore, rotavirus vaccination should be considered due to its benefits of preventing rotavirus-associated diseases.

Medullary carcinoma of the thyroid gland(MTC) constitutes approximatesly 3% to 10% of all malignant thyroid tumors. It appears in both familial and sporadic forms. Metastases are frequently present at diagnosis and are resistant to chemotherapy and radiotherapy. Surgical resection of the primary tumor and the metastases is the mainstay of treatment. Although MTC can be detected by elevated serum calcitonin, localization of residual or metastatic foci may be difficult. Many scintigraphic methods have been used for identification of the residual tumor or metastasis. However, most of them have either low sensitivity or low specificity. MTC frequently secretes somatostatin and may express somatostatin receptors. Recently, somatostatin-receptor imaging has been known to be useful for the detection of residual and recurrent medullary thyroid carcinoma. A 25 year-old woman who was dignosed as medullary carcinoma by biopsy of thyroid mass is presented. Thirteen years ago, she underwent left thyroidectomy due to thyroid cancer(MTC). Laboratory tests revealed an increase in the levels in serum CEA(CEA=557.6 ng/ml) and calcitonin(calcitonin= 720 pg/ml). The second patient, a 30 year-old female, complained of a palpable mass in the left anterior neck. Ten years ago, she underwent a right lobectomy of thyroid gland due to adenomatous goiter. Laboratory tests revealed an increase in the levels in serum CEA(CEA=617 ng/ml) and Calcitonin (Calcitonin=2,300 pg/ml). In both cases, pre- and postoperative In-111 pentetreotide scintigraphy were done and compared with "'I scintigraphy. In-111 pentetreotide scan may be useful for the localization of residual or metastatic medullary thyroid carcinoma. Further study is warranted to define the sensitivity and specificity of the technique.
