PURPOSE: The objective of this study was to analyse the content of health-textbooks in elementary school in order to offer the basic data required for development or revision of health-textbook for elementary school. METHODS: This study was methodological study of the content of health-textbooks. The study sample consisted of 10 health-textbooks of elementary school which were edited in 2009~2010. The components of contents divides into holistic analysis and specific areas. RESULTS: One textbook was no introductory remarks and 2 textbooks were no preface. The health-textbooks consisted of 7 areas and were comprehensive for school education. The proportion of each was different in 10 textbooks. Sexuality and health was accounted for the largest portion of the seven areas in both the fifth and sixth grade. However, given that the mortality rate for the child's safety accidents is higher than in developed countries, the proportion of accident prevention and first aid can be relatively weak area. CONCLUSION: It is essential that health-textbooks empower schoolers to make healthy decisions through the promotion of useful life skills that provide a more integrated concept of health. Therefore, there is a need for approaches to health textbook to integrate more values of health.

The K antigen, one of the 38 immunogenic antigens in the Kell blood group system, can cause severe hemolytic transfusion reactions (HTR) and hemolytic disease of the fetus and newborn (HDFN). The frequency of incidence of the K antigen varies by race (9.02% of Western populations are K＋ compared to 0.0% in Koreans), and the incidence and causes of anti-K vary accordingly. Anti-K have occasionally been detected in antibody screening/identification tests, but no hemolytic transfusion reactions have been reported in Korea so far. We conducted a retrospective review of nine cases of anti-K identified at the Samsung Medical Center over the past five years, most of which involved Koreans. No clear causes, such as the transfusion of K antigen-positive donor blood, pregnancy, or infections known to trigger anti-K, were identified. It has been speculated that the increased immigration of people of different races with the K antigen might be a reason for the anti-K formation. However, given the frequency of K＋ reported in recent literature and observed in our study, it is suggested that these “unknown causes” may be more common than previously believed. Hence, prospective studies are warranted to identify these causes more accurately.

Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity and mortality. Twin pregnancy and cesarean delivery are well-known risk factors for PPH. However, few studies have investigated PPH risk factors in mothers who have undergone cesarean delivery for twin pregnancies. Therefore, this study investigated the risk factors associated with severe PPH after cesarean delivery for twin pregnancies. Methods: We searched and reviewed the Korean Health Insurance Review and Assessment Service’s claims data from July 2008 to June 2021 using the code corresponding to cesarean delivery for twin pregnancy. Severe PPH was defined as hemorrhage requiring red blood cell (RBC) transfusion during the peripartum period. The risk factors associated with severe PPH were identified among the procedure and diagnosis code variables and analyzed using univariate and multivariate logistic regressions. Results: We analyzed 31,074 cesarean deliveries for twin pregnancies, and 4,892 patients who underwent cesarean deliveries for twin pregnancies and received RBC transfusions for severe PPH were included. According to the multivariate analysis, placental disorders (odds ratio, 4.50; 95% confidence interval, 4.09– 4.95; P < 0.001), general anesthesia (2.33, 2.18–2.49; P < 0.001), preeclampsia (2.20, 1.99–2.43; P < 0.001), hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome (2.12, 1.22–3.68; P = 0.008), induction failure (1.37, 1.07–1.76; P = 0.014), and hypertension (1.31, 1.18–1.44; P < 0.001) predicted severe PPH. Conclusions: Placental disorders, hypertensive disorders such as preeclampsia and HELLP syndrome, and induction failure increased the risk of severe PPH after cesarean delivery for twin pregnancy

PURPOSE: This study examined and compared the associations of the iron status and food intake with the blood lead, mercury, and cadmium concentrations among Korean adolescent girls, premenopausal women, and postmenopausal women. METHODS: The data from the 2010~2011 Korea National Health and Nutrition Examination Survey (KNHANES) was used. The subjects were classified into three groups: adolescent girls (n = 268), premenopausal women (n = 1,157), and postmenopausal women (n = 446). The iron status was assessed by hemoglobin, hematocrit, serum ferritin, and iron concentrations, as well as the total iron binding capacity (TIBC). The food intake was estimated by a food frequency questionnaire. RESULTS: The blood heavy metal concentrations and poisoning rate in postmenopausal women were higher than in the other groups. The iron status in the adolescent girls and postmenopausal women was higher than that in the premenopausal women. In the adolescent girls, the iron status was inversely associated with the blood cadmium concentration. The dairy food intake was inversely related to the blood lead and cadmium concentrations. In premenopausal women, the iron status was inversely associated with the cadmium concentrations. The fish and shellfish food intakes were positively associated with the mercury concentrations. In postmenopausal women, the iron status was positively associated with the mercury and cadmium concentrations. Fast foods and fried foods were inversely associated with the lead concentration. CONCLUSION: The premenopausal women showed a lower iron status than the adolescent girls and postmenopausal women. The associations of the iron status with the blood heavy metal concentrations were different among the adolescent girls, premenopausal women, and postmenopausal women. In addition, the relationships of the food intakes with the blood heavy metal concentrations differed among adolescent girls, premenopausal women, and postmenopausal women. Further studies will be needed to confirm these findings.

PURPOSE: The objective of this study was to examine the effect of the body shape discordance, the difference between true body type based on body mass index (BMI) and self-recognized body image, on nutrient intake, weight control attempt, and mental health in Korean adults. METHODS: Subjects were persons aged 19~64 years (4,382 men and 6,226 women) who participated in the 2010~2012 Korea National Health and Nutrition Examination Survey. Subjects were categorized as RL (Group recognized as lighter than BMI criteria), RA (Group with agreement between BMI criteria and self-recognized body image), and RH (Group recognized as heavier than BMI criteria) according to the difference between actual body type based on BMI and self-recognized body image. RESULTS: Means of BMI in RH groups were lower than or equal to that of RA groups in all groups. No significant differences in total energy intake were observed among the three groups in men, but total energy intake was higher in the RL group than in the RH group in 30~49 year old women. Proportion of carbohydrate was the highest in the RL group among 30~49 year old women. RH groups paid more attention to weight control and had less weight gain than other groups. Higher proportions of depressive symptoms were reported in the RH group in 19~29 year old men, while a higher proportion of depressive symptoms were reported in the RL group in 50~64 year old men. CONCLUSION: The current findings suggest an association of perceiving body shape with energy intake, weight control attempt, or depressed mood in some age groups. Body image perception can influence eating, weight control attempt, and depressed mood, therefore proper body image perception should be established in Korean adults.

IgG4-related disease (IgG4-RD) is a new disease entity characterized by elevated serum IgG4 and infiltration of IgG4+ plasma cells in tissue. IgG4-RD can involve various organs, and skin could also be affected. The manifestations of IgG4-related skin disease (IgG4-RSD) are not characteristic, however it usually presents with multiple erythematous nodules or plaques with itching sensation. We report two cases of IgG4-RSD. Histological studies of these cases revealed infiltration of numerous plasma cells and mononuclear cells in the entire dermis. Some plasma cells were strongly positive for IgG4 stain. IgG4-RSD is a treatable disease with systemic corticosteroids. Thus, clinicians should obtain a biopsy and identify IgG4-positive cells for an accurate diagnosis.
