We report a case of a large asymptomatic Rathke cleft cyst in a 14-year-old boy. This cyst was of considerable size, measuring 2x1.8x1.8 cm, but did not produce any symptoms and was confined to the suprasellar area. The cyst wall was lined by pseudostratified ciliated columnar epithelium with goblet cells. The lining epithelium of the Rathke cleft cyst was immnoreactive for cytokeratin, EMA and CEA.

We experienced two cases of occupational asthma induced by Elk dander in Elk-feeders and confirmed these cases by the bronchial provocation test with Elk dander. Both of them showed dual asthmatic response. They also showed positive reaction to the skin prick test with EIK dander. Now one of them has no asthmatic symptoms at all after complete avoidnce of EIK dander.

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.

PURPOSE: Vitamin D deficiency rickets is a significant public health problem that results from insufficient exposure to sunlight and inadequate vitamin D supplementation. The purpose of this study is to identify the clinical characteristics of vitamin D deficiency rickets in infants. METHODS: Data of 35 infants diagnosed as vitamin D deficiency rickets at Sanggye-Paik Hospital, Seoul, Korea, from March 2007 to May 2009 were reviewed. Children with plasma 25-hydroxyvitamin D levels <15 ng/mL and 15-30 ng/mL were considered to have vitamin D deficiency and vitamin D insufficiency, respectively. RESULTS: Thirty-five infants (22 boys, 13 girls) were diagnosed with rickets. Mean age at diagnosis was 7.4+/-7.1 months (range: 0.1-29.8 months). Eighteen infants (51%) were vitamin D deficient and seventeen infants (49%) were insufficient. Twenty-eight of all (80%) diagnosed as subclinical rickets. Twenty-nine infants (83%) were below the age of 12months. Twenty infants (57%) had breastfed and ten infants (29%) had iron deficiency anemia. Nine of breastfed infants (45%) were vitamin D deficient and ten of their mothers were vitamin D insufficient. Overall, radiographic evidence of rickets was present in 93% of the cases. Radiographic sign of rickets was evident even in vitamin D insufficient state. CONCLUSION: It is important for the clinician to screen for subclinical vitamin D deficiency rickets in inadequately supplemented infants by pairing 25-hydroxyvitamin D levels with wrist radiographs. A nationwide epidemiological study of vitamin D deficiency rickets must be conducted and evidence-based national guidelines must be defined to prevent rickets.

BACKGROUND: It is well known that Korea is one of the endemic areas for viral hepatitis B and those who are positive for HBsAg has been reported to be about 5-10% in Korea. Since the 1980s, research and population education for prevention and vaccination for hepatitis B were implemented in Korea. Therefore, we predicted that the positive rates of HBsAg and Anti-HBs have changed since then. Young adults are considered to be the main candidates for hepatitis B vaccination, and the change in the rate of prevalence of HBsAg and Anti-HBs has been investigated in this study. METHODS: We surveyed 3760 freshmen who were positive for HBsAg and Anti-HBs who were in 1998. HBsAg and Anti-HBs was tested by RPHA/PHA. RESULTS: 3760 students included 2780 males and 980 females(mean age 19.44 years). Among them, 128(3.4%) was positive for HBsAg and 2488(66.2%) was positive for Anti-HBs. The positive rate of HBsAg was 105(3.8%) and that of Anti-HBs was 179(64.7%) among 2780 male students. The positive rate of HBsAg was 23(2.3%) and that of Anti-HBs was 691(70.5%) among 980 female students. CONCLUSIONS: As compared with previous prevalence studies of HBsAg and Anti-HBs, the positive rate of HBsAg was decreased and that of Anti-HBs was increased. The researchers hope that farther study is necessary using wider range of subjects.

In the current years, it has now become necessary to establish standards for micronutrient intake based on scientific evidence. This review discusses issues related to the development of the 2020 Dietary Reference Intakes for Koreans (KDRI) for magnesium (Mg), zinc (Zn), and copper (Cu), and future research directions. Following issues were encountered when establishing the KDRI for these minerals. First, characteristics of Korean subjects need to be applied to estimate nutrient requirements. When calculating the estimated average requirement (EAR), the KDRI used the results of balance studies for Mg absorption and factorial analysis for Zn, which is defined as the minimum amount to offset endogenous losses for Zn and Mg. For Cu, a combination of indicators, such as depletion/repletion studies, were applied, wherein all reference values were based on data obtained from other countries. Second, there was a limitation in that it was difficult to determine whether reference values of Mg, Zn, and Cu intakes in the 2020 KDRI were achievable. This might be due to the lack of representative previous studies on intakes of these nutrients, and an insufficient database for Mg, Zn, and Cu contents in foods. This lack of database for mineral content in food poses a problem when evaluating the appropriateness of intake. Third, data was insufficient to assess the adequacy of Mg, Zn, and Cu intakes from supplements when calculating reference values, considering the rise in both demand and intake of mineral supplements. Mg is more likely to be consumed as a multi-nutrient supplement in combination with other minerals than as a single supplement. Moreover, Zn-Cu interactions in the body need to be considered when determining the reference intake values of Zn and Cu. It is recommended to discuss these issues present in the 2020 KDRI development for Mg, Zn, and Cu intakes in a systematic way, and to find relevant solutions.

PURPOSE: Although breast milk is considered the best source of nutrition for infants because of its superiority over powdered milk, there are circumstances when breast milk is unavailable. Committee on Nutrition of the Korean Pediatric Society conducted an investigation into the current status of formula feeding in Korea. METHODS: This investigation was conducted using questionnaires produced by our committee and distributed to mothers of children under the age of two who were using formula feeding at 10 university hospitals and 22 public health centers nationwide between March 1999 to September 1999. A comparative analysis according to location, birth order, mother's occupation, education, housing tenure and normal birth status was performed on all 2696 questionnaires using the chi-square test. RESULTS: Formula feeding was found in 49.4% and formula feeding combined with breast milk were 21.5% of the respondents. The percentage of formula feeding was higher in working mothers who underwent a Cesarean section in metropolitan areas. The inadequacy of breast milk was the most common reason for feeding powdered rnilk followed by the unhealthy condition of the mother and mother's return to work. Of those investigated, 94.9% said that they changed products at each stage as recommended by the manufacturer. Promotions for special formulas were more active in metropolitan areas than other areas, and 57.7M said that they used special formulas based on recornmendations by the doctor and acquaintances(15.5%) or after seeing an advertisement(14.0%). CONCLUSION: This investigation revealed that many rnothers were misinformed concerning formula feeding and pediatricians should provide mothers with education, shedding light on proper feeding methods.

This study aimed to define a one portion size of food items frequently consumed for convenient use by Koreans in food selection, diet planning, and nutritional evaluation. We analyzed using the original data on 5,436 persons (60.87%) aged 20 ~ 64 years among 8,930 persons to whom NHANES 2005 and selected food items consumed by the intake frequency of 30 or higher among the 500 most frequently consumed food items. A total of 374 varieties of food items of regular use were selected. And the portion size of food items was set on the basis of the median (50th percentile) of the portion size for a single intake by a single person was analyzed. In cereals, the portion size of well polished rice was 80 g. In meats, the portion size of Korean beef cattle was 25 g. Among vegetable items, the portion size of Baechukimchi was 40 g. The portion size of the food items of regular use set in this study will be conveniently and effectively used by general consumers in selecting food items for a nutritionally balanced diet. In addition, these will be used as the basic data in setting the serving size in meal planning.
