Kim JH, Yu JJ, Lee J, Kim MN, Ko HK, Choi HS, Kim YH, Ko JK. Detection rate and clinical impact of respiratory viruses in children with Kawasaki disease. KOREAN JOURNAL OF PEDIATRICS 2012; 55:470-3. [PMID: 23300502 PMCID: PMC3534160 DOI: 10.3345/kjp.2012.55.12.470] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/03/2012] [Revised: 10/01/2012] [Accepted: 10/22/2012] [Indexed: 12/15/2022]
Abstract
Purpose The purpose of this prospective case-control study was to survey the detection rate of respiratory viruses in children with Kawasaki disease (KD) by using multiplex reverse transcriptase-polymerase chain reaction (RT-PCR), and to investigate the clinical implications of the prevalence of respiratory viruses during the acute phase of KD. Methods RT-PCR assays were carried out to screen for the presence of respiratory syncytial virus A and B, adenovirus, rhinovirus, parainfluenza viruses 1 to 4, influenza virus A and B, metapneumovirus, bocavirus, coronavirus OC43/229E and NL63, and enterovirus in nasopharyngeal secretions of 55 KD patients and 78 control subjects. Results Virus detection rates in KD patients and control subjects were 32.7% and 30.8%, respectively (P=0.811). However, there was no significant association between the presence of any of the 15 viruses and the incidence of KD. Comparisons between the 18 patients with positive RT-PCR results and the other 37 KD patients revealed no significant differences in terms of clinical findings (including the prevalence of incomplete presentation of the disease) and coronary artery diameter. Conclusion A positive RT-PCR for currently epidemic respiratory viruses should not be used as an evidence against the diagnosis of KD. These viruses were not associated with the incomplete presentation of KD and coronary artery dilatation.

Abstract
High-dose intravenous immunoglobulin (IVIG) therapy is the highly effective and standard treatment for Kawasaki disease (KD). However, ~20 % of KD patients have persistent fever or recurrence of fever after the initial IVIG treatment, which increases the risk for coronary artery lesions (CALs). Furthermore, the mechanism of IVIG resistance in KD patients still is unknown. The number of CC chemokine ligand 3-like 1 (CCL3L1) gene copies is reported to be associated with KD and IVIG resistance in Japanese patients. In addition, the authors observed significant upregulation of the CCL3L1 gene expression after in vitro immunoglobulin treatment in B cell lines derived from KD patients. Therefore, this study of 459 KD patients and 496 healthy control subjects tested whether the number of CCL3L1 gene copies is associated with a risk of KD, CALs, and/or IVIG resistance in Korean KD patients. However, the number of CCL3L1 gene copies was not associated with KD (P = 0.18), CAL formation (P = 0.062), or the IVIG resistance (P = 0.90). Therefore, the results indicate that the number of CCL3L1 gene copies does not have a role in susceptibility to KD or CALs nor with IVIG resistance in Korean KD patients.

Abstract
This study was performed in 145 pigs to develop a population pharmacokinetics (PPK) model by i.m. administration of cefquinome (CEQ) at the dose of 2 mg/kg in the neck muscle. Serum physiological and biochemical parameters for each pig were determined before administration. After administration, 2-4 samples were collected at random, with the sampling point evenly distributed in the three periods (<1 h, 1-4 h and >4 h). The plasma concentration of CEQ was determined by high performance liquid chromatography with UV detector. The pharmacostatistical analyses of concentration-time data, weight, age, gender, serum physiological and biochemical parameters were performed with nonlinear mixed effect modeling (NONMEM). A one-compartmental model with first-order absorption and elimination adequately described the data from the study group. The optimal random effect model of pharmacokinetics parameters was of log-normal distribution and the residual errors assumed a mixed-type model (proportional and additive) to best explain intra-individual variability. Covariate analysis showed that body weight is positively correlated with apparent volume of distribution (V/F) and body clearance (CL/F). The typical PPK parameters of Ka , CL, and V were 0.564/h, 5.15 L/h, and 1.36 L, respectively.

Abstract
The Connor-Davidson Resilience Scale (CD-RISC) is a brief self-rating questionnaire for measuring resilience. The aims of the present study were to describe the development of a Korean version of the CD-RISC (K-CD-RISC) and to more firmly establish its psychometric properties in terms of reliability and validity. The participants consisted of a general population sample (n=194) and psychiatric outpatients (n=127) with non-psychotic mood or anxiety disorders. The K-CD-RISC score means (standard deviation) were 65.9 (13.6) in the general population and 50.4 (20.5) in the psychiatric outpatients. The mean score of the general population was significantly higher than that of the psychiatric outpatients. Exploratory factor analysis revealed five factors, and the obtained factor structure was verified through confirmatory factor analysis. In the general population, the Cronbach's α coefficient of the K-CD-RISC was found to be 0.92. Greater resilience was found to be associated with less perceived stress, anxiety and depression and with higher levels of positive affect and purpose in life. Taken together, our findings suggest that the K-CD-RISC has good psychometric properties and is a valid and reliable tool for assessing resilience.

Abstract
OBJECTIVE The effects of celecoxib, a selective cyclo-oxygenase-2 (COX-2) inhibitor, on HeLa cervical cancer cell growth and radiosensitivity were investigated. METHODS Cytotoxicity was quantified using a 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyltetrazolium assay and effects on radiosensitivity were assessed using the lethal dose, quasithreshold dose, fraction surviving after 2 Gy irradiation and the radiosensitization ratio (SER, based on average lethal dose) determined using a single-hit multitarget model. RESULTS Celecoxib inhibited HeLa cell proliferation in a concentration- and time-dependent manner, with a half-maximal inhibitory concentration at 72 h of 44 μmol/l. Treatment with 20 μmol/l celecoxib for 72 h before irradiation was associated with an SER of 2.01. The SER of irradiated cells was 2.41 when treated with 40 μmol/l celecoxib before irradiation, 1.89 when treated simultaneously and 1.44 when treated after irradiation. Celecoxib downregulated COX-2 and vascular endothelial growth factor C (VEGF-C) expression evaluated immunohistochemically. CONCLUSION Celecoxib pretreatment radiosensitizes HeLa cells via a mechanism dependent on down-regulation of COX-2 and VEGF-C.

Abstract
Rubinstein-Taybi syndrome (RTS) is characterized by peculiar facies, mental retardation, broad thumbs, and great toes. Approximately one-third of the affected individuals have a variety of congenital heart diseases. They can also have upper airway obstruction during sleep, due to hypotonia and the anatomy of the oropharynx and airway, which make these patients susceptible to obstructive sleep apnea (OSA). In our case, pulmonary hypertension was caused, successively, by congenital heart defects (a large patent ductus arteriosus and arch hypoplasia) and obstructive sleep apnea during early infancy. The congenital heart defects were surgically corrected, but persistent pulmonary hypertension was identified 2 months after the operation. This pulmonary hypertension was due to OSA, and it was relieved by nasal continuous positive airway pressure. This case is the first report of pulmonary hypertension from OSA in a young infant with RTS.

Abstract
Several authors suggested that the clinical characteristics of incomplete presentation of Kawasaki disease are similar to those of complete presentation and that the 2 forms of presentation are not separate entities. Based on this suggestion, a diagnosis of incomplete Kawasaki disease in analogy to the findings of complete presentation is reasonable. Currently, the diagnosis of incomplete Kawasaki disease might be made in cases with fewer classical diagnostic criteria and with several compatible clinical, laboratory or echocardiographic findings on the exclusion of other febrile illness. Definition of incomplete presentation in which coronary artery abnormalities are included as a necessary condition, is restrictive and specific. The validity of the diagnostic criteria of incomplete presentation by the American Heart Association should be thoroughly tested in the immediate future.

Abstract
Background and Objectives Pulmonary arterial stenosis is a relatively common complication after corrective operation of congenital heart disease. Unilateral stenosis of pulmonary arteries could result in decrease perfusion of affected lung, pulmonary regurgitation, or elevation of right ventricular pressure. Eventually there are increasing risks of right ventricular failure, arrhythmia, or sudden death. However we have limited data of pulmonary arterial stent in paediatric population as the treatment of branch pulmonary stenosis. This study aimed at validating the effectiveness and investigating complications of pulmonary arterial stent implantation in a single institution during mid-term follow up period. Subjects and Methods A total of 42 patients (50 stents) were implanted for treating branch pulmonary arterial stenosis. We used cardiac catheterization for comparing diameter after stent implantation directly and lung perfusion scan indirectly. We also investigated any adverse effect relating the procedure. Results Percent stenosis of stenotic lesions were decreased from 54.1±10.7% to 22.8±12.5% (p<0.001) and degree of decrement in affected lung perfusion was declined from 22.7±8.0% to 10.3±9.0% (p<0.001) immediately and lasts during mid-term follow up period. Complication rate relating the procedure was 12% (6 out of 12) and there was no mortality case. Conclusion This series showed immediate and short term effectiveness of pulmonary arterial stent in congenital heart defects. We concluded that percutaneous transcatheter implantation of pulmonary arterial stent was safe and effective during short and mid-term follow up period.

Abstract
Surgical skill and strategy for the correction of tetralogy of Fallot (TOF) have improved and resulted in satisfactory outcomes. However, prematurity and low birth weight continue to remain risk factors for poor outcomes. We present a case of a 2,150 g neonate born with TOF, in whom palliation was achieved with right ventricular outflow tract (RVOT) stenting. Seventy-seven days after the procedure, stenosis of RVOT below the stent was identified. At that time his body weight was 4.9 kg and total corrective surgery was deemed feasible. Eight months following surgical repair, the patient remained well without medical intervention. RVOT stenting may be a viable interim procedure while waiting for a low birth weight neonate born with TOF and prostaglandin E1 dependency to reach optimal weight to undergo corrective surgery.

Abstract
OBJECTIVE Because perivascular echo brightness (PEB) of coronary arteries has been proposed as a criterion for diagnosis of incomplete Kawasaki disease, we assessed the clinical importance of PEB during the acute phase of disease. STUDY DESIGN We enrolled 58 patients with Kawasaki disease who underwent two-dimensional strain analysis of images of pericoronary tissue taken during the acute and the convalescent phases. Echogenicity of pericoronary tissue and of the blood pool was determined by speckle tracking in the respective areas of imaging as the averages of integrated backscatter over a single cardiac cycle. PEB was defined as echogenicity of pericoronary tissue minus blood pool. RESULTS PEB did not differ in the acute phase in patients and control subjects (P = .10) and between phases of disease (P = .25). In comparison between patient groups, the presence of pericardial effusion was higher in patients with higher PEB during the acute phase (n = 30) than in the remaining patients (33% versus 4%, P < .01). CONCLUSIONS PEB did not differ between patients and control subjects and is only associated with the presence of pericardial effusion during the acute phase of Kawasaki disease. Our data do not confirm the reliability of PEB as a useful diagnostic sign of incomplete Kawasaki disease.

Abstract
Purpose Brain natriuretic peptide (BNP) has been considered a biochemical marker for myocarditis in Kawasaki disease. We performed this study to determine its quantitative significance. Methods We attempted to correlate log-transformed BNP concentrations (log-BNP) and clinical, laboratory, and echocardiographic variables in 81 children with Kawasaki disease. Stepwise multiple linear regression analysis was used to determine the variables independently associated with log-BNP concentration. Results Serum C-reactive protein level (P<0.0001), serum alanine aminotransferase concentration (P=0.0032), white blood cell count (P=0.0030), and left ventricular mass index (P=0.0024) were positively related with log-BNP, and hemoglobin level (P<0.0001), serum albumin level (P<0.0001), Na+ concentrations (P<0.0001), left ventricular fractional shortening (P=0.0080), and peak early diastolic tissue velocity of the left ventricular basal lateral segment (P=0.0045) were negatively related to the log-BNP concentration. Multiple regression analysis showed that serum albumin concentration (R2=0.31, P=0.0098) and left ventricular mass index (R2=0.09, P=0.0004) were significantly associated with the log-BNP concentration. Conclusion Elevated BNP levels during the acute phase of Kawasaki disease may be attributable to cardiac dysfunction associated with the increase in left ventricular mass, and log-BNP concentration may be a quantitative biochemical marker of myocarditis in Kawasaki disease.

Abstract
BACKGROUND Optimal management of muscular ventricular septal defects (MVSD) is still not determined in the current era. Moreover, long-term left ventricular function after closure of MVSD is not well known. Thus, we investigated surgical outcomes including long-term left ventricular function after closure of MVSD through left ventriculotomy. METHODS We conducted a retrospective review of medical records of 20 children who underwent MVSD closure between March 1993 and August 2010. There were 10 boys (50%) and 10 girls (50%). Patient age ranged from 1.6 to 103.4 months (median, 26.4 months), and body weight from 2.8 to 31.5 kg (median, 11.9 kg). Electrocardiogram results were normal sinus rhythm in all except 1 patient with congenital complete atrioventricular block. There were 16 patients who previously had palliative pulmonary artery banding procedures before closure of MVSD. There were 13 patients (65%) with Swiss-cheese type VSD. RESULTS There was 1 hospital death of a patient with congenital complete atrioventricular block with pacemaker malfunction (5%). There was 1 late death of a patient with del 22q with adenoviral pneumonia. There was no reoperation. Median follow-up duration was 85.9 months (range, 4.7 to 166.7). The location of MVSD was apical portion in 10 patients (50%) and midtrabecular portion in 9 patients (45%). There were 6 Dacron patch closures and 13 direct closures of MVSD through left ventriculotomy. There was no complete atrioventricular block. Last follow-up echocardiographic data showed normal ejection fraction with 65.2% ± 8.2% after closure of MVSDs. There was no leakage in 8 patients; 11 patients had insignificant leakage, which disappeared spontaneously in 4 patients 17.9 months (median value) after operation. CONCLUSIONS Our acceptable long-term results of left ventricular function after left ventriculotomy proved that this technique might be a viable option in the management of MVSD.

Abstract
This study aimed to investigate left ventricular myocardial deformation in children with Kawasaki disease during the acute phase of their illness. A total of 50 patients and 35 normal control subjects were assessed. Data were obtained from the patients during the acute and convalescent phases of Kawasaki disease. Analyses of myocardial deformation [strain (epsilon), strain rate (SR)] was performed using two-dimensional speckle-tracking imaging in three directions (longitudinal, circumferential, and radial) at the basal and mid levels of the left ventricular myocardium. Basal longitudinal epsilon (P < 0.001) and midlongitudinal epsilon (P < 0.0001) were lower during the acute phase of the disease than in the control subjects and associated with serum albumin level and left ventricular mass index (LVMI). Midlongitudinal SR (P < 0.0001) was lower during the acute phase of Kawasaki disease than in the control subjects and associated with LVMI. Decreased systolic SR was not detected in any direction. In conclusion, left ventricular longitudinal systolic epsilon was significantly decreased during the acute phase of Kawasaki disease. This may be a result of myocardial swelling from myocarditis during the acute phase of the disease.

Abstract
The main purpose of this study was to examine the bidirectional relation between parental knowledge and self-control among South Korean youth using a nationwide cross-sequential data. Data included early adolescents (N = 2,844, mean age at Wave 1 = 9.86 years) and middle adolescents (N = 3,449, mean age at Wave 1 = 13.79 years) over the 3 and 4 yearly assessments, respectively. Latent growth curve models revealed that the relation between parental knowledge and adolescent self-control was not a unidirectional phenomenon, but rather bidirectional dynamic set of interactive processes. Evidence of reciprocal influences indicated that higher initial levels of adolescents' perceptions of parental knowledge of their whereabouts and activities predicted slower rates of increase in their self-control and that higher initial levels of self-control predicted slower rates of increase in parental knowledge over time. The results point to the importance of a bidirectional, transactional view for understanding parent-adolescent interactions.

Abstract
The main purpose of the present study was to investigate self-criticism as a potential mediating factor in the link between mother-adolescent relationships with aggression and perceptions of social competence. The sample consisted of 888 older (M = 14.3 years) and younger (M = 11.6 years) adolescent children from the same family. Maternal self-criticism strongly corresponded to the quality of relationships with children, and an intergenerational similarity in levels of self-criticism, particularly for older children, was found. Mother-adolescent relationships and adolescent self-criticism were significantly related to aggression and perceptions of social competence. In addition, results supported the hypothesis that self-criticism in adolescents mediates the link between mother-adolescent relationships and social competence.

Abstract
Moyamoya disease is a cerebrovascular disorder of unknown cause, characterized by slowly progressive bilateral stenosis or occlusion of the internal carotid arteries and produces collateral vessels. Moyamoya syndrome has rarely been reported in association with Graves' disease, especially in children. Several reports suggest that a cerebral infarction might have occurred in patients with clinical and laboratory evidence of hyperthyroid function. We report a case of Moyamoya disease in a girl with Down syndrome and thyrotoxicosis, and we review the relevant literature. To our best knowledge, this is the first report of Moyamoya disease associated with thyrotoxicosis in a young person in Korea.

Abstract
As a more effective in vivo drug delivery system, several methods loading anti-cancer drugs to biodegradable and biocompatible nano-particles have been explored and developed. Supposedly due to the enhanced permeability and retention (EPR) effect, systemic administration of these nano-particles have been found to result in accumulation of nano-particles into solid tumors. In this study, we prepared nano-particles using polyethylene glycol (PEG)/poly-L-lactide (PLLA) diblock copolymer and loaded doxorubicin into these nano-particles (Nano-dox). The fabricated nano-particles exhibited sustained release kinetics of the drug in vitro. To follow the in vivo biodistribution of 200-350 nm sized nano-dox particles in tumor (syngenic renal cell adenocarcinoma: RENCA) bearing mouse, the carboxylfluorescenin diacetate succinimidyl ester (CFSE) was loaded into the nano-particles. Nano-dox accumulated preferentially in tumors; however, in terms of its anti-tumor efficacy, it did not show any marked benefits, compared to freely-administered doxorubicin. This result suggests the need to re-consider and evaluate what type of anti-cancer reagents we to be used in the ongoing efforts of coupling drug delivery system with tumor EPR effects.
