The term "pineal anlage tumor" has been recently proposed and few cases have been reported. We report the first Korean case of pineal anlage tumor in a 6-year-old girl who complained of headache and vomiting for 2 months. Brain MRI revealed a well defined, lobulated, calcifying mass in the pineal region. Tumor was totally removed. Pathological examination revealed a primitive pineal parenchymal tumor with melanotic epithelial component that was similar to histologic findings of melanotic neuroectodermal tumor of infancy, so-called retinal anlage tumor and of the developing pineal gland. The tumor was composed mostly of small, undifferentiated cells, Flexner-Wintersteiner rosettes, and ganglionic differentiation. The tumor also contained the cartilage and skeletal muscle cells.

Oral mucositis continues to be a major complaint of patients who have chemotherapy for the acute leukemia. An innovative and inexpensive remedy which produces favorable results for those afficted is not yet introduced. So we tried to develop two oral care protocols for reducing the level of oral mucositis during cytotoxic therapy through literature review and our clinical experience. The one is sodium bicarbonate-normal saline gargling, and the other consists of chlorhexidine gargling. This quasi-experimental study was performed to compare the efficacy of these two different oral care protocols. Twenty subjects were assigned to one of the two specific diagnosis of leukemia, aim of the chemotherapy. The Oral Assessment Guide(OAG), the Beck's perception of oral comfort, WHO Grading system fot mucositis and the discomfort of oral gargling solution were used to assess oral status and subject's oral discomfort during chemotherapy. Each subjects were observed daily from the start of the chemotherapy until Absolute Neutrophil Count(ANC) reached 1,000. It continued about 2-4 weeks. The data analyzed by Mann-Whittney U test and ANCOVA. The result was follows as: The patient who used sodium bicarbonate-normal saline gargling showed significantly higher mean score of the discomfort of oral gargling solution than chlorhexidine gargling. The other scores were not significantly different between two groups. However the subjects using the sodium bicarbonate-normal saline gargling showed a lower level of oral mucositis. We concluded that oral using sodium bicarbonate-normal saline gargling was between to reduce the level of oral mucositis during chemotherapy and nursing assessments of the oral cavity seemed to promote patient's compliance with the oral care regimen.

To differentiate the postoperative changes from the recurrence of tumor and to evaluate MR imaging of early postoperative leptomeningeal seeding in medulloblastoma, We have retrospectively analysed 34 cases of MR images of 17 patients who were confirmed as medulloblastoma by histopathology. Noncontrast and postcontrast T1 weighted MR images were obtained in all patients. In 11 patients follow-up MR was done more than once (average:1.5 times) and average interval of MR imaging was 6 months. The timing of 34 MR images was as follow: 6 case within 2 months, 9 cases between 2 months and 1 year, 19 cases more than 1 year after surgery respectively. MR images within 2 month after surgery revealed contrast enhancement at operation site and adjacent meninges, hemorrhage, residual tumor. In patients who had no evidence of tumor recurrence, these early postoperative changes were markedly decreased within 6 month after sugery. MR images obtained more than 1 year after sugery showed no abnormal contrast enhancement or mild focal dural enhancement at operation site. Diffuse moderate dural enhancement was noted in one patient who had the history of post-surgical subdural hemorrhage. In six patients with tumor recurrences which were detected from as early as 9months to 6 years after surgery, the findings of recurrence included leptomeningeal enhancement of brain stem and cerebellar surface at early stage, variable sized enhancing leptomeningeal nodules, linear or irregular sulcus obliterating enhancing lesions, enhancing mass at primary or metastatic site. We have concluded that leptomeningeal enhancement detected after 6 months of surgery is an important MR finding suggesting the possibility of tumor recurrence. Small nodular and linear enhancement of leptomeninges at brainstem or cerebellar surface is considered as the early manifestation of intracranial tumor seeding.

The incidence of ectopic pregnancy is a marked increase in both the absolute number and rate in recent years. But dramatic decrease in death from ectopic pregnancies probably due to improved diagnosis and management. The aim of the study was to investigate the effect of intramuscular Methotrexate(MTX) injection on the treatment of ectopic pregnancy. The method of the study was made by the retrospective clinical observations on the 32 cases of unruptured ectopic pregnancies in Chung Goo Sung Sim hospital, department of Obstetrics & Gynecology. The results were as follows: 1) The most frequent age group was 25-29 year group(37.5%). 2) Nullipara was 31.3% and the case who experienced artificial abortion was 75%. 3) A previous history of abdominal or pelvic surgery was in 40.6% and pelvic inflammatory in 6.3%. 4) The mean ectopic gestational week was 6.4 weeks, 5) On symptomatological analysis, lower abdominal pain was encounted 53.1%, vaginal spotting was 40.6%. 6) The resolution of patients was obtained in 29 cases(90.6%)of 32 unruptured tubal pregnancies with intramuscular methotrexate treatment. 7) The mean resolution duration was 23.8 days. 8) The side effects of methotrexate were observed in 10 cases(31.2%)of 32 unruptured tubal pregnancies, but the severity of symptoms was mild. Consequently, tveatment by intramuscular injection of MTX expects to be one of the therapies alternating to surgery. However success rate remained 90.6% with and toxicity rate 31.2% with MTX injection. Therefore patients selection criteria and MTX dosage adjustment are more stricdy required for rising success rate and avoidance of toxic complication.

8.Effectiveness of the Self-determination Theory based a Motivational Interviewing YOU-TURN Program for Smoking Cessation among Adolescents.
Journal of Korean Academy of Nursing 2015;45(3):347-356
PURPOSE: In this study, the effectiveness of a motivational interviewing smoking cessation YOU-TURN program for adolescents was examined. The program was based on the self-determination theory. METHODS: The study was carried out with a nonequivalent control group pretest-posttest design. Participants in the present study were 136 high school students living in D city. The students were assigned to the experimental group (n=52) who participated in the motivational interviewing smoking cessation YOU-TURN program based on self-determination theory, or to the control group (n=84) who participated in a general smoking cessation program. Data were collected from September 1, 2013 through April 30, 2014. Collected data were analyzed using SPSS PC+ 21.0 with Chi-square test, Fisher's exact test, t-test, Mann-Whitney U test, Repeated Measures ANOVA, and MANOVA-Wilk's Lambda. RESULTS: The experimental group had a significant increase in basic psychological needs, and duration of quitting-smoking in comparison with the control group. The experimental group had a significant decrease in cigarettes smoked per day and cotinine in urine in comparison with the control group. CONCLUSION: The motivational interviewing YOU-TURN program, when delivered to adolescents who smoked, was effective in discouraging smoking, and can be utilized as an effective nursing intervention for adolescents who smoke.

OBJECTIVES: The purpose of this study was to find the protective effects of garlic on the halogenated hydrocarbon induced hepatotoxicities, and the possible protection mechanisms involved. METHODS: Male Sprague-Dawley rats received garlic (0.5 %) or regular diet, for 4 weeks. This was followed by a single dose of corn oil (the controls), carbon tetrachloride (400mg/kg body weight) and trichloroethylene (2,000mg/kg body weight) being administered to each diet group. Blood samples were collected 24 hours following the administration, and the serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities measured. The liver samples were studied for their cytochrome P450 and CYP2E1 contents, lipid peroxidation and histopathology. RESULTS: The results for the group receiving the 0.5 % garlic diet showed a slight decrease of CYP2E1 expression compared with the regular diet group. Carbon tetrachloride was significantly decreased the CYP2E1 contents in both the regular and garlic diet groups, but the trichloroethylene remained unchanged. Garlic did not decrease the lipid peroxidation of the liver in the control group, but attenuated the increase of lipid peroxidation caused by carbon tetrachloride. Garlic attenuated the increase of both the serum AST and ALT activities caused by carbon tetrachloride. The histopathological observations also showed that garlic attenuated centrilobular necrosis and vacuolar degenerative changes significantly in the carbon tetrachloride treated group. Conclusions : The results indicate that garlic attenuates the carbon tetrachloride-induced hepatotoxicity, through the prevention of the metabolic activation and lipid peroxidation.

OBJECTIVES: Cadmium (Cd), a toxic and non-essential metal, is recognized as a human carcinogen, which has a tendency to accumulate in the human body. The levels of Cd in renal cortex and liver are good indicators as an index of Cd exposure in the general population. In this study, we present an estimation of reference Cd levels in tissue (renal cortex and liver) and total body burden in the general population of Korea. MEDTHODS: Cd and zinc (Zn) were analyzed in renal cortex and liver from 254 autopsies (male : 188 cases, female : 66 cases) aged 0 to 87 years. RESULTS: Geometric mean concentration of Cd was 27.4 and 3.1 ua/g wet weight in renal cortex and liver, respectively. The level of Zn in renal cortex and liver was 35.4 and 42. 6 v/g wet weight, respectively. The result suggests that kidney is the target organ for Cd accumulation. The accumulation of Cd in renal cortex was age-dependent with a biphasic pattern. The level of Cd in renal cortex increased with age up to the fifties, and then leveled off thereafter. Based on the data, the regression model for Cd accumulation in renal cortex by age is predicted by : Log KCd = 0. 2325 + 0. 0553 Age 0. 0005 Age. The highest Cd accumulation in renal cortex of Koreans was estimated at 43. 3 ua/g wet weight at 50. 8 years old. In addition, the total Cd body burden by age was estimated by the following equation: Total Cd Body Burden = -4. 5948 + l. 2278 Age - 0. 0121 Age. The highest body burden of Cd was estimated at 26. 5 mg at age 50. 7 years in the Korean general population. The positive correlation between Zn and Cd was observed in renal cortex and liver. CONCLUSIONS: The level of Cd exposure in Korean was found to be lower than in Japanese, but same as or higher than in American and Europeans.
