PurposeActivation of Toll-like receptor 2 (TLR2) present on circulating monocytes in patients with Kawasaki disease (KD) can lead to the production of proinflammatory cytokines and interleukin-10 (IL-10). We aimed to determine the association of the frequency of circulating TLR2+/CD14+ monocytes (FTLR2%) with the outcomes of KD, as well as to compare FTLR2% to the usefulness of sIL-10.MethodsThe FTLR2% in patients with KD was measured by flow cytometry. Serum levels of IL-10 (sIL-10) were determined in 31 patients with KD before the initial treatment with intravenous immunoglobulin (IVIG) and in 21 febrile controls by using enzyme-linked immunosorbent assay. Patients were classified as having coronary artery lesions (CALs) based on the maximal internal diameters of the proximal right coronary artery and proximal left anterior descending coronary artery one month after the initial diagnosis.ResultsWe found that FTLR2% greater than 92.62% predicted CALs with 80% sensitivity and 68.4% specificity, whereas FTLR2% more than 94.61% predicted IVIG resistance with 66.7% sensitivity and 71.4% specificity. Moreover, sIL-10 more than 15.52 pg/mL predicted CALs and IVIG resistance with 40% and 66.7% sensitivity, respectively, and 73.7% and 76.2% specificity, respectively.ConclusionWe showed that measuring FTLR2% before the initial treatment could be useful in predicting CAL development with better sensitivity than sIL-10 and with results comparable to sIL-10 results for the prediction of IVIG resistance in patients with KD. However, further studies are necessary to validate FTLR2% as a marker of prognosis and severity of KD.

PurposeObesity is an important risk factor for hypertension in adolescents. We investigated the relationship of obesity-related indices (body mass index [BMI], waist-to-height ratio [WHR], and body fat percentage [%BF]) with blood pressure and the hemodynamic determinants of blood pressure in Korean adolescents.MethodsIn 2008, 565 adolescents, aged 12-16 years, were examined. The %BF of the participants was measured by bioelectrical impedance analysis. Echocardiography and brachial artery pulse tracing were used to estimate the stroke volume (SV), cardiac output (CO), total vascular resistance (TVR), and total arterial compliance (TAC).ResultsWe noted that BMI, WHR, and %BF were positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP). The positive correlation between BMI and blood pressure (SBP and DBP) persisted after adjustment for WHR and %BF. However, after adjustment for BMI, the positive associations between blood pressure (SBP and DBP) and WHR as well as %BF, were not noted. With regard to the hemodynamic factors, BMI, but not WHR and %BF, was an independent positive factor correlated with SV and CO. TVR had an independent negative association with BMI; however, it was not associated with WHR or %BF. Moreover, we noted that BMI, WHR, and %BF did not affect TAC.ConclusionIn Korean adolescents, BMI had an independent positive correlation with SBP and DBP, possibly because of its effects on SV, CO, and TVR. WHR and %BF are believed to indirectly affect SBP and DBP through changes in BMI.

School bullying has become a major social problem in Korea after the emergence of media reports on children who committed suicide after being victimized by bullies. In this article, we review the characteristics of bullying, and investigate the role of the pediatrician in the prevention of and intervention against bullying and school violence. Bullying can take on many forms such as physical threat, verbal humiliation, malicious rumors, and social ostracism. The prevalence of bullying in various countries is approximately 10% to 20%. In Korea, the prevalence of school violence is similar but seems to be more intense because of the highly competitive environment. From our review of literature, we found that children who were bullied had a significantly higher risk of developing psychosomatic and psychosocial problems such as headache, abdominal pain, anxiety, and depression than those who were not bullied. Hence, it is important for health practitioners to detect these signs in a child who was bullied by questioning and examining the child, and to determine whether bullying plays a contributing role when a child exhibits such signs. Pediatricians can play an important role in the prevention of or intervention against school violence along with school authorities, parents, and community leaders. Moreover, guidelines to prevent school violence, such as the Olweus Bullying Prevention Program, KiVa of the Finish Ministry of Education, and Connected Kids: Safe, Strong, Secure of the American Academy Pediatrics, should be implemented.

for gender, age, and height on ≥three occasions. Knowing that blood pressure values increase in children as they grow older, the purposes of this study were to measure blood pressure by an oscillometric device and to determine normal values and percentile curves for children. Methods :Systolic and diastolic blood pressures were measured twice with an oscillometric device in 3,545 boys and 3,145 girls under six years of age, in Seoul. Using this data, we determined average blood pressure values and percentile curves based on gender and age; we subdivided these values into blood pressures of 50 th , 90 th , 95 th , and 99 th percentiles, by percentile of height. The regression coefficients and standard deviations of the systolic and diastolic blood pressure values were obtained from linear regression models. Results :Older boys and girls had higher systolic and diastolic blood pressure values. Older boys and girls in the same percentile of height for age had higher systolic and diastolic blood pressure values. Taller boys and girls within the same age group had higher systolic and diastolic blood pressure values. Conclusion :Blood pressure standards based on gender, age, and height were obtained via an oscillometric method. Llimitation of this study is that the study population was not from the whole country, but exclusively from Seoul. Nonetheless, the data from this study will be helpful in diagnosing and managing hypertension in Korean children. (Korean J Pediatr 2008;51:998-1006)

Purpose : Since the infant formula milk has been produced in Korea, it has faced a low rate of breast milk feeding, though breast milk feeding is a little increasing. Therefore, the Korean Pediatric Society launched its website for breast-feeding consultation to provide information to the general public and enhance the health of growing infants. The consultation results were analyzed to identify the problems that mothers encounter during breast-feeding. Methods : From August 1, 2004 to July 31, 2007, 1001 mothers who visited the online consultation webpage (www. pediatrics.or.kr) of the Korean Pediatric Society asked 1,021 questions. The questions were divided into 3 major categories and 14 specific categories. Interesting questions asked more than 100 times were retrospectively analyzed. Results : The results for the major categories were as follows: 413 questions (40.3%) were on how to breast-feed, 315 (30.8%) on problems of feeding mothers, and 293 (28.8%) on problems of the fed babies. In the specific categories, 22.2% of the questions were on how to breast-feed. With the increasing number of working couples and working mothers, many questions were asked on the problems of breast-feeding after returning from work. Conclusion : The author expects that analyses of these consultations will contribute to the enhancement of information on the consultation website, thus enabling to provide clearer answers to people's increased interest in and concerns on breast-feeding. Furthermore, this research will help to establish correct breast-feeding practice.

Purpose:Neonatal lupus is characterized by congenital complete heart block(CCHB), cutaneous rash, and laboratory abnormalities in infants born to mothers with systemic lupus erythematosus(SLE). This study aims to examine the incidence of CCHB and clinical outcome in neonates born to mothers with SLE. Methods:The study group consisted of 49 neonates, born from 57 pregnancies of 55 women with SLE, diagnosed at Hanyang University Hospital for the period between January 1997 and January 2005. Clinical and laboratory data were retrospectively identified from medical record. Results:There were 5(8.8 percent) spontaneous abortions and one(1.8 percent) still births among 57 pregnancies of 55 mothers. Of 49 live births, 15(26.3 percent) were premature and eight(12.3 percent) were small for their gestational age. There was one(1.8 percent) CCHB suspected during pregnancy on fetal echocardiograpy in a fetus of mother with systemic lupus erythematosus and the fetus was not born by artificial abortion because of mother. There was no CCHB among EKG findings of 49 newborns. Laboratory testing showed hematologic abnormalities among 25.6 percent(10/39) of the babies. 5.1 percent(2/39) and 7.7 percent(3/39) of them were diagnosed as neutropenia, and thrombocytopenia was seen respectively. Anti-SSA(Ro) and antiphospholipid antibodies were predictive factors for prematurity(P=0.003, P=0.049). Anticardiolipin antibodies were predictive factors for ventilatory care(P=0.018). Conclusion:The incidence of CCHB among neonates born to mothers with SLE, which was measured in this study, was lower than that in earlier studies. A high incidence of hematologic abnormalities was found in our study. It is suggested that careful examination should be made of skin for the diagnosis of neonatal lupus.

Purpose: Obesity is an important risk factor for hypertension in adolescents. We investigated therelationship of obesity-related indices (body mass index [BMI], waist-to-height ratio [WHR], and body fatpercentage [%BF]) with blood pressure and the hemodynamic determinants of blood pressure in Koreanadolescents. Methods: In 2008, 565 adolescents, aged 12-16 years, were examined. The %BF of the participantswas measured by bioelectrical impedance analysis. Echocardiography and brachial artery pulse tracingwere used to estimate the stroke volume (SV), cardiac output (CO), total vascular resistance (TVR), andtotal arterial compliance (TAC). Results: We noted that BMI, WHR, and %BF were positively correlated with systolic blood pressure(SBP) and diastolic blood pressure (DBP). The positive correlation between BMI and blood pressure(SBP and DBP) persisted after adjustment for WHR and %BF. However, after adjustment for BMI, thepositive associations between blood pressure (SBP and DBP) and WHR as well as %BF, were not noted.With regard to the hemodynamic factors, BMI, but not WHR and %BF, was an independent positivefactor correlated with SV and CO. TVR had an independent negative association with BMI; however, itwas not associated with WHR or %BF. Moreover, we noted that BMI, WHR, and %BF did not affect TAC. Conclusion: In Korean adolescents, BMI had an independent positive correlation with SBP and DBP,possibly because of its effects on SV, CO, and TVR. WHR and %BF are believed to indirectly affect SBPand DBP through changes in BMI. [ABSTRACT FROM AUTHOR]
