To elucidate the relationship among the levels of nutrients intake, bone mineral density (BMD) and the urinary biochemical markers of bone metabolism, this survey is conducted with 225 postmenopausal women over 50 years of age. The urinary biochemical markers including deoxypyridinoline (DPD) and Ca excretion were measured. Bone mineral densities of lumbar spine (L2-L4), femoral neck, ward's triangle and trochanter were measured with dual-energy X-ray absorptiometry and the nutrient intake data obtained by 24 hr recall method. Mean age of all subjects was 64.8 years old, and the BMDs of the subjects were 0.86 g/cm2 (lumbar spine), 0.60 g/cm2 (femoral neck), 0.49 g/cm2 (trochanter), and 0.41 g/cm2 (ward's triangle). The results were compared among 3 groups with different nutrient intake levels classified by the percentage of Dietary Reference Intakes (DRIs) for Koreans as follows: low < 75% DRIs, 75% DRI < or = adequate < 125% DRIs, high > or = 125% DRIs. Bone mineral density of adequate protein intake group was significantly higher than those of low and high protein intake groups (p < 0.05). Urinary DPD excretion was lowest in protein and calcium adequate intake groups (p < 0.05, p < 0.05), respectively. In relation to urinary Ca excretion, it is revealed to be considerably lower in the groups taking protein and vitamin C adequate intake (p < 0.05, p < 0.05). The percent DRI of protein and calcium were positively correlated with the BMD of the femoral neck after adjusted age (p < 0.05, p < 0.05). These results showed that there are probably some relationships between nutrient intake levels and urinary biochemical markers. For postmenopausal women with adequate nutrition expecially protein, calcium and vitamin C, has an important role to postpone bone resorption and to prevent the decrease of bone density.

This study assessed the effects of soy isoflavones supplementation with exercise on urinary mineral (calcium, magnesium, copper, zinc) excretion as an index of bone resorption rates in 67 postmenopausal women. A total subjects were assigned to Isoflavone (90 mg/day) or placebo groups. These groups were further divided into groups that undergone a regular exercise or a rather sedentary state performing daily activity only. We conducted study eight week period. Result showed urinary zinc excretion was more significantly decreased in the isoflavone-sedentary group (-180.76 +/- 171.30 ug/day) than in the placebo-sedentary group (-31.23 +/- 146.60 ug/day), placebo-exercise group (40.93 +/- 193.44 ug/day) and isoflavione-exercise group (-1.21 +/- 160.61 ug/day) (p < 0.05), but no significant changes in the differences between the values of the pre and post study values in urinary calcium, magnesium and copper excretion. These results suggest that Isoflavone supplementation decrease urinary zinc excretion rate in postmenopausal subjects.

OBJECTIVE: To investigate individual pretreatment serum human chorionic gonadotropin (hCG) cutoff value for medical treatment success with single-dose and multi-dose regimen of methotrexate in tubal ectopic pregnancy. METHODS: Eighty-five women who received methotrexate for the treatment of tubal ectopic pregnancy during 2003 to 2015 were selected. Fifty-three women received a single-dose regimen and 32 women received a multi-dose regimen. Medical treatment failure was defined as necessity of surgical treatment. The medical treatment success rate was estimated in both regimens and the pretreatment serum hCG titer to predict the success was assessed by receiver operating characteristics curve analysis. RESULTS: Pretreatment clinical and laboratory parameters were similar between group of single-dose regimen and multi-dose regimen. Treatment success rate was 64.2% in the single-dose regimen group and 71.9% in the multi-dose regimen group (P>0.05). Pretreatment serum hCG titer was an independent prognostic factor for treatment success in each regimen. Serum hCG cutoff value to predict the treatment success was 3,026 IU/L in single-dose regimen group and 3,711 IU/L in multi-dose regimen group. CONCLUSION: We recommend use of single-dose regimen when pretreatment serum hCG <3,026 IU/L but multi-dose regimen may be favored when initial serum hCG level between 3,026 and 3,711 IU/L.

The purpose of this study was to investigate the relationship between nutrient intakes and blood parameters of cardiovascular function in 40 female college students on self-selected diet in Chungnam. Anthropometric measurements, analysis of dietary intakes and blood composition were conducted. Serum levels of triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol, CK-MB, and LDH were measured by biochemical analyzer. The results were summarized as follows. The mean age of the subjects was 22.5+/-7.2 years. The weight, height and BMI were 52.4+/-7.2kg, 161.3+/-5.7cm and 20.2+/-2.4, respectively. Daily energy and lipid intakes were 1634.2+/-437.7kcal and 46.8+/-17.0g. And the ratio of carbohydrate, protein, and lipid to energy intake was 59.2 : 14.5 : 26.3. Serum concentrations appeared to be 61.1+/-24.2mg/dl(triglyceride), 141.2+/-33.0mg/dl(total cholesterol), 64.8+/-20.1mg/dl(HDL-cholesterol), 64.1+/-25.4mg/dl(LDL-cholesterol), 7.2+/-3.2IU/iota (CK-MB), 107.9+/-23.4IU/iota (LDH). In the relation between nutrient intakes and serum parameters, vitamin B1 intake showed positive correlation with triglyceride, HDL-cholesterol, and CK-MB, respectively(p<0.001, p<0.05, p<0.05). Vitamin B2 intake had positive correlation with triglyceride(p<0.05). And vitamin C intake had negative correlation with HDL-cholesterol(p<0.05). From these results, it is suggested that the intakes of micro nutrients such as vitamin B1, vitamin B2, vitamin C have relation with cardiovascular function in female college students. However, further systematic research is needed to investigate the functions of micro nutrients in healthy persons for prevention of chronic diseases.

Ramsay Hunt syndrome (RHS) is a disease caused by varicella-zoster virus (VZV) infection that can be diagnosed through clinical symptoms with or without imaging evaluations. The typical features of RHS on imaging evaluation include signal changes and enhancement in the internal auditory canal (IAC) nerves, and the labyrinthine segment of cranial nerve VII (CN VII) and cranial nerve VIII (CN VIII). In some patients, inner ear structure (cochlear and vestibular apparatus) is involved in RHS. Neurologic complications, such as encephalitis and meningitis, are rare in RHS, but are known to occur. Therefore, magnetic resonance imaging (MRI) is necessary to detect both abnormal signal intensity in the IAC, CN VII, CN VIII, inner and ear structure, and CNS complications. We report an RHS patient with CN VII, VIII, and leptomeningeal enhancement within the cerebellar folia on 10-min delayed, contrast-enhanced (CE), three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) imaging.

Intake of soy protein the fisk factors associated with cardiovascular disease in postmenopausal women. This study was designed to effects of isoflavone supplementation on serum lipids in 16 hyperlipidemic postmenopausal women . For this purpose, an intervention study was conducted for 12 weeks. Subjects were healthy, free-living women consuming habitual diets with 0.3g/d of isoflavone. Food and nutrient intake was obtained by 24-hr recall method and anthropometric measurement were made. Systolic and diastolic blood pressure, total serum cholesterol. HDL-cholesterol and LDL-cholesterol were determined before and after the isoflavone supplementation. The results were summarized as follows. The average age, hight, weight and BMI of the subject were 65.3 years, 151.4 cm, 62.2 kg and 27.1, respectively. The systolic blood pressure and diastolic blood pressure were not reduced significantly with isoflavone supplementation. Total cholesterol (p<0.001), HDL-C(p<0.05), and LDL-C(p<0.01) were significantly increased after isoflavone concentration. In conclusion, isoflavone supplementation was not effective to modify risk factors for cardiovascular disease.

OBJECTIVES: The purpose of this study is to evaluate the preliminary effects of school-based short term mental health awareness and school bullying prevention programs. METHODS: From April to December 2013, the Child and Adolescent Mental Health Promotion team of Seoul National Hospital conducted school-based short term social skill training (N=56, 4 sessions), mental health awareness (N=84, 4 sessions) and school bullying prevention programs (N=171, 1 session) in elementary and junior high schools located in Seoul. The changes in the subjects before and after the program were assessed. RESULTS: The a social skills training program improved the 'helping' behaviors in boys (t=-2.355, p<.05) and 'sharing' (t=-3.223, p<.01), 'cooperation' (t=-2.235, p<.05), and 'comforting' (t=-2.830, p<.01) behaviors in girls, assessed using the Prosocial Behavior Questionnaire. The mental health awareness program improved 'general health awareness' (t=2.620, p<.05), measured using the Korean General Health Questionnaire. The school bullying prevention program resulted in decreased 'self esteem' (t=3.769, p<.01), measured using the Self Esteem Scale and decreased 'anger' (t=4.198, p<.01), assessed using the Novaco Anger Scale. CONCLUSION: The results of our preliminary analysis suggest that school-based mental health awareness and school bullying prevention programs may be effective even when conducted for a short term. Future investigation is necessary in order to validate the long term effects of these programs.

OBJECTIVES: "Internet-addiction" came into common use not only in clinical setting but also in everyday life. But, pathophysiology and diagnostic criteria of the internet addiction remain unknown. Because adolescents are in developing period, they might be vulnerable to the internet addiction, depression and sleep-related problem. The objectives of this study were to investigate the characteristics of internet addiction and its association with sleep pattern and depression in Korean adolescence. METHODS: Subjects were 799 middle and high school students in Seoul, Korea. We administered a self-reported questionnaire including socio-demographic data, Korean versions of Young's Internet Addiction Scale (YIAS), Pittsburgh Sleep Quality Index (PSQI), the Center for Epidemiologic Studies for Depression Scale (CES-D) and questions about internet using patterns. Data of 696 subjects were included in analysis. Chi-square tests were used to analyze proportional differences, and ANOVA with post-hoc tests were used to analyze differences among groups. Partial correlation analyses were performed to analyze the correlation of internet addiction with other variables (two-tailed, p<0.05). RESULTS: Of the 696 participants (grade 2 of middle school;M2 135 vs. grade 1 of high school;H1 238 vs. grade 2 of high school;H2 323), 2.0% (n=14) were internet-addicted (IA), 27.7% (n=193) were over-using (OU) and 70.3% (n=489) were not-addicted (NA). The mean scores of YIAS, PSQI and CES-D scores were 35.24+/-12.78, 5.53+/-3.04 and 16.72+/-8.69, respectively. In higher grade students, average total sleep time was shorter (M2 426.20+/-67.68 min. vs. H1 380.47+/-62.57 min. vs. H2 354.67+/-73.37 min., F=51.909, p<0.001), and PSQI (4.69+/-3.14 vs. 5.42+/-3.15 vs. 5.97+/-2.83, F=8.871, p<0.001) CES-D (13.53+/-8.37 vs. 16.96+/-8.24 vs. 17.87+/-8.84, F=12.373, p<0.001) scores were higher than those of lower grade students. Comparing variables among IA, OU and NA groups, computer using time not for study (96.36+/-63.31 min. vs. 134.92+/-86.79 min. vs. 213.57+/-136.87 min., F=34.287, p<0.001) and portable device using time not for study (84.22+/-79.11 min. vs. 96.97+/-91.89 min. vs. 152.31+/- 93.64 min., F=5.400, p=0.005) were different among groups. PSQI (5.26+/-2.97 vs. 6.08+/-2.97 vs. 7.50+/-4.41, F=8.218, p<0.001) and CES-D scores (15.40+/-8.08 vs. 19.05+/-8.42 vs. 30.43+/-13.69, F=32.692, p<0.001) were also different among groups. YIAS score were correlated with computer using time not for study (r=0.356, p<0.001) and portable device using time not for study (r=0.136, p<0.001). PSQI score (r=0.237, p<0.001) and CES-D score (r=0.332, p<0.001). YIAS score and PSQI score (r=0.131, p=0.001), YIAS and CES-D score (r=0.265, p<0.001), PSQI score and CES-D score (r=0.357, p<0.001) were correlated each other. CONCLUSION: These results suggested that adolescents' internet-addiction was correlated with not only computer and portable device using time not for study but also depression and sleep-related problems. We should pay attention to depression and sleep-related problems, when evaluating internet-addiction in adolescents.
