Abstract
Kawasaki disease (KD) is an extremely rare condition in infants younger than 3 months old. Cardiovascular complications are unfortunately most common in young infants and it is in this age group, incomplete Kawasaki disease (IKD) is more frequently reported. Because IKD is a diagnostic dilemma, any sign that could help early diagnosis, such as BCG reactivation is useful. Here we report on an infant less than 3 months old with IKD wherein, BCG reactivation helped us in making the diagnosis. In this article, we highlight the usefulness of this sign for early diagnosis of IKD, especially in countries where BCG vaccination is still part of the immunization schedule.

Abstract
A 21-year-old man with no known medical history presented with substernal chest pain. Serial 12-lead electrocardiography showed dynamic ST-segment elevations in the anterolateral leads. Emergent coronary angiography revealed diffuse coronary aneurysmal disease and thrombotic occlusion of the left anterior descending coronary artery. The patient underwent urgent coronary artery bypass grafting. Subsequent imaging showed intracerebral aneurysms that involved his right and left middle cerebral arteries. The incidence, multiple causes, and proposed mechanisms of coronary artery aneurysmal formation are discussed, as is the rare association of these lesions with extracardiac arterial aneurysms.This association between coronary and extracardiac aneurysms is a phenomenon that warrants further study to determine its prevalence and possible causes. Findings could influence recommendations for further screening of patients diagnosed with coronary aneurysmal disease.

Abstract
Survival of patients with congenital heart defects has improved dramatically. Many will undergo interventional catheter or surgical procedures later in life. Others will develop atherosclerotic or post-surgical coronary heart disease. The coronary artery anatomy in patients with congenital heart disease differs substantially from that seen in the structurally normal heart. This has implications for diagnostic procedures as well as interventions. The unique epicardial course seen in some defects could impair interpretation of coronary angiograms. Interventional procedures, especially at the base of the heart, risk injuring unusually placed coronary arteries so that coronary artery anatomy must be delineated thoroughly prior to the procedure. In this review, we will describe the variants of coronary artery anatomy and their implications for interventional and surgical treatment and for sudden death during late follow-up in several types of congenital heart defects including: tetralogy of Fallot, truncus arteriosus, transposition of the great arteries, double outlet right ventricle, congenitally corrected transposition of the great arteries and defects with functionally one ventricle. We will also discuss the coronary abnormalities seen in Kawasaki disease.

Abstract
BACKGROUND The optimal management of Kawasaki disease (KD) unresponsive to intravenous immunoglobulin (IVIG) therapy remains unclear. OBJECTIVE To prospectively evaluate the efficacy and safety of intravenous methylprednisolone pulse (IVMP) therapy in KD cases unresponsive to additional IVIG. METHODS KD patients who initially received IVIG (2 g/kg/24 h) and acetylsalicylic acid within nine days after disease onset were studied. Patients who did not respond received additional IVIG (2 g/kg/24 h), and those who still did not respond were given IVMP (30 mg/kg/day) for three days, followed by oral prednisolone. The response to treatment, echocardiographic findings and adverse effects were evaluated. RESULTS Among 412 KD cases, 74 (18.0%) were treated with additional IVIG; 21 (28.4%) of the latter cases subsequently received IVMP followed by prednisolone. All cases became afebrile soon after IVMP infusion and did not have a high-grade fever during treatment with prednisolone for two to six weeks. Four weeks after disease onset, coronary artery lesions (CAL) were diagnosed according to the Japanese Ministry of Health and Welfare or the American Heart Association criteria in two of the 21 cases treated with IVMP plus prednisolone; among all 412 cases, three (0.7%) and eight (1.9%) had CAL according to each criteria, respectively. All CAL regressed completely one year after disease onset. Adverse effects of IVMP, such as hypothermia and sinus bradycardia, resolved spontaneously. CONCLUSIONS In KD patients unresponsive to additional IVIG, IVMP promptly induced defervescence, and subsequent oral prednisolone suppressed recurrence of fever. IVMP followed by prednisolone therapy may prevent CAL, without severe adverse effects.

Abstract
OBJECTIVE To retrospectively compare the imaging characteristics of retropharyngeal density and associated findings for Kawasaki disease with those for non-Kawasaki disease, and identify the distinguishing features which aid the CT diagnosis of Kawasaki disease with retropharyngeal low density. MATERIALS AND METHODS Among the enhanced neck CT performed in children less than 8-years old with clinical presentation of fever and cervical lymphadenopathy over a 6-year period, only cases with retropharyngeal low density (RLD) were included in this study. The 56 cases of RLD were divided into two groups; group A included cases diagnosed as Kawasaki disease (n = 34) and group B included cases diagnosed as non-Kawasaki disease (n = 22). We evaluated the CT features including the thickness of RLD and its extent into the deep neck spaces, as well as soft tissue change in the adjacent structure. We also scored the extent of RLD into the deep neck spaces and the soft tissue changes in the adjacent structure. RESULTS The thickness of RLD was greater in group A than in group B (group A, 6.0 ± 2.1; group B, 4.6 ± 1.5, p = 0.01). The score of the RLD extent into the deep neck spaces was significantly greater in group A than in group B (group A, 2.3 ± 1.3; group B, 0.8 ± 1.0, p < 0.01). Also, the score of the adjacent soft tissue changes was greater in group A than in group B (group A, 2.0 ± 1.1; group B, 1.0 ± 1.0, p < 0.01). CONCLUSION If children present with fever and cervical lymphadenopathy that display retropharyngeal low density with extension into more deep neck spaces as well as changes in more adjacent soft tissue, the possibility of Kawasaki disease should be considered.

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 and Objectives We sought to determine parameters to guide the decision of retreatment in patients with Kawasaki disease (KD) who remained febrile after initial intravenous immunoglobulin (IVIG). Subjects and Methods A total of 129 children with KD were studied prospectively. Patients were treated with IVIG 2 to 9 days after the onset of disease. Laboratory measures, such as white blood cell (WBC), percentage of neutrophils, C-reactive protein (CRP), and N-terminal pro-brain natriuretic peptide (NT-proBNP), were determined before and 48 to 72 hours after IVIG treatment. Patients were classified into IVIG-responsive and IVIG-resistant groups, based on the response to IVIG. Results Of a total of 129 patients, 107 patients (83%) completely responded to a single IVIG therapy and only 22 patients (17%) required retreatment: 14 had persistent fever and 8 had recrudescent fever. There was no significant difference between the groups in age, gender distribution, and duration of fever to IVIG initiation, but coronary artery lesions developed significantly more often in the resistant group than in the responsive group (31.8% vs. 2.8%, p=0.000). Compared with pre-IVIG data, post-IVIG levels of WBC, percentage of neutrophils, CRP, and NT-proBNP decreased to within the normal range in the responsive group, whereas they remained high in the resistant group. Multivariate logistic regression indicated that neutrophil counts, CRP, and NT-proBNP were independent parameters of retreatment. Conclusion Additional therapy at an early stage of the disease should be administered for febrile patients who have high values of CRP, NT-proBNP, and/or neutrophil counts after IVIG therapy.

Abstract
Kawasaki disease (KD) occurs most often in children from one to three years of age. It is a common systemic vasculitis that is rare in children older than eight years of age or younger than six months of age; however, it may occur in these age groups. Boys are affected more often than girls by a ratio of 1.5 to 1. The mean annual incidence rate reported in a recent Canadian study was 13/100,000 children younger than five years of age. The highest incidence rates occur in Japan. The purpose of the present paper is to help the clinician to recognize KD in children. In particular, the paediatrician must be aware of situations in which KD poses a diagnostic challenge, such as KD in an infant younger than six months of age and the child who presents with a prolonged, unexplained fever but insufficient criteria to make a diagnosis of KD.

Abstract
Compared with adults, cardiac emergencies are infrequent in children and clinical presentation is often quite variable. In adults, cardiac emergencies are most commonly related to complications of coronary artery disease; however, in pediatric cases, the coronaries are only rarely the underlying problem. Pediatric cardiac emergencies comprise a range of pathology including but not limited to undiagnosed congenital heart disease in the infant; complications of palliated congenital heart disease in children; arrhythmias related to underlying cardiac pathology in the teenager and acquired heart disease. The emergency room physician and pediatric intensivist will usually be the first and second lines of care for pediatric cardiac emergencies and thus it is imperative that they have knowledge of the diverse presentations of cardiac disease in order to increase the likelihood of delivering early appropriate therapy and referral. The objective of this review is to outline cardiac emergencies in the pediatric population and contrast the presentation with adults.

Abstract
Kawasaki disease is the acute febrile vasculitis of childhood, predominantly affecting medium sized arteries with predilection for coronary arteries. The diagnosis is mainly clinical, though investigations are helpful in early detection of complications. We report a case of Kawasaki disease in a 5 year old child who presented to our hospital with conjunctival congestion, lymphadenopathy and fever. When on treatment with antibiotics did not help resolve symptoms, particularly conjunctival congestion Kawasaki disease was suspected. She was treated with a single dose of intravenous immunoglobulin G, over a period of 12 h. She subsequently developed a systolic murmur with grade I mitral regurgitation not a known complication of Kawasaki disease. She responded to the treatment remarkably and promptly thus evading any fatal complication.

Abstract
Kawasaki disease is an acute febrile disease predominantly seen in young children. We report a case of Kawasaki disease in a 32-year-old pregnant woman. She developed a generalized erythematous skin rash accompanied by high fever. Bilateral conjunctival congestion, tender cervical lymphadenopathy, an edematous lower lip and peripheral edema followed by desquamation were observed. She was successfully treated with aspirin and intravenous gammaglobulin (1 g/kg/day). Her course was not complicated by coronary artery aneurysm and she delivered a healthy baby. To the best of our knowledge, this is the first case of Kawasaki disease in a pregnant woman. We suggest that Kawasaki disease should be included in the differential diagnosis of a generalized, erythematous skin rash accompanied by high fever in adults.

Abstract
PURPOSE Exaggerated pro-inflammatory reactions during the acute phase of Kawasaki disease (KD) suggest the role of immune dysregulation in the pathogenesis of KD. We investigated the profiles of T regulatory cells and their correlation with the clinical course of KD. METHODS Peripheral blood mononuclear cells were collected from 17 KD patients during acute febrile and subacute afebrile phases. T cells expressing CD4, CD25, and Foxp3 were analyzed using flow cytometry, and the results were correlated with the clinical course of KD. RESULTS The percentage of circulating CD4(+)CD25(high)Foxp3(+) T cells among CD4(+) T cells was significantly higher during the subacute afebrile phase than during the acute febrile phase (1.10%±1.22% vs. 0.55%±0.53%, P=0.049). Although levels of CD4(+)CD25(low)Foxp3(+) T cells and CD4(+)CD25(-)Foxp3(+) T cells were only slightly altered, the percentage of CD4(+)CD25(+)Foxp3(-) T cells among CD4(+) T cells was significantly lower during the subacute afebrile phase than during the acute febrile phase (2.96%±1.95% vs. 5.64%±5.69%, P=0.036). Consequently, the ratio of CD25(high)Foxp3(+) T cells to CD25(+)Foxp3(-) T cells was higher during the subacute afebrile phase than during the acute febrile phase (0.45%±0.57% vs. 0.13%±0.13%, P=0.038). CONCLUSION Decreased CD4(+)CD25(high)Foxp3(+) T cells and/or an imbalanced ratio of CD4(+)CD25(high)Foxp3(+) T cells to CD4(+)CD25(+)Foxp3(-) T cells might play a role in KD development. Considering that all KD patients were treated with intravenous immunoglobulin (IVIG), recovery of CD4(+)CD25(high)Foxp3(+) T cells during the subacute afebrile phase could be a mechanism of IVIG.

Abstract
Purpose Kawasaki disease (KD) is the main cause of acquired heart disease in children. In addition to cardiovascular involvement, many complications have been recognized in KD. However, respiratory complications have been rarely reported. We investigated the differences in clinical characteristics, laboratory findings, radiography findings, and echocardiography findings of Mycoplasma pneumoniae infection and other types of pneumonia in KD patients. Methods Among 358 patients with KD, 54 developed concurrent pneumonia. Among the 54 patients, 12 (22.2%) with high titers of anti-M. pneumoniae antibody (AMA) (>1:640) were grouped in the M. pneumoniae group and 42 were included in the control group. Serum AMA was measured in each patient. Clinical laboratory findings and total duration of fever were analyzed. Results The duration of fever, serum hemoglobin, white blood cell count, platelet count, erythrocyte sedimentation rate, C-reactive protein level, albumin level, and the incidence of coronary arterial lesions showed no statistical difference in the 2 groups. Neutrophil count was significantly higher in the M. pneumoniae group than in the control group. Among various radiography findings observed in pneumonia, consolidation and pleural effusion were more frequent in the M. pneumoniae group than in the control group. On the other hand, parahilar peribronchial opacification, diffuse interstitial lesion, and normal findings prevailed in the control group. Conclusion KD patients can have concurrent infections, especially pulmonary symptoms. The cause of KD is likely to be associated with M. pneumoniae infection. Thus, immediate treatment of M. pneumoniae infection in KD patients is very important.

Abstract
During the past 15 years, clinical experience with catheter interventional treatment in patients with Kawasaki disease, including balloon angioplasty, stent implantation, rotational ablation, and transluminal coronary revascularization, has been gradually increasing. Because the coronary artery lesions in Kawasaki disease involve severe calcifications, the indications or catheter intervention techniques have not been established for adult patients with Kawasaki disease. Satisfactory acute results for coronary balloon angioplasty have been obtained in patients with a relatively short interval from the onset of disease, especially within 6 years; however, the incidence of restenosis after angioplasty is still high. Rotational ablation may be the most appropriate catheter intervention technique for patients with Kawasaki disease. The advantage of rotational ablation is the high success rate, even in patients with calcified coronary artery stenosis. Stent implantation requires larger arterial access and is not possible in younger children. Care should be paid to the detection of newly-formed aneurysms, as the formation of new aneurysms is associated with the use of additional balloon angioplasty using high pressure balloon inflation. Anticoagulation or anti-platelet regimens are essential for long-term management. Coronary intervention in Kawasaki disease requires special techniques and knowledge of cardiovascular involvement. The procedure should be managed under the close collaboration between pediatric cardiologists and coronary interventional cardiologists.

Abstract
BACKGROUND Respiratory virus infections in children are a leading cause of morbidity and mortality worldwide. METHODS A total of 897 clinical specimens were collected from February 2007 to January 2008 and transported to the National Influenza Center. Two hundred and two samples belonged to children under the age of six from 897 specimens, described above, were selected. Then they were tested for influenza virus types and subtypes by real time PCR assay subsequently, the specimens were tested for RSV and hMPV by hemi-nested multiplex PCR and parainfluenza viruses type 1-4 by hemi-nested multiplex PCR and adenovirus by hemi-nested PCR. RESULTS The throat swab was taken from the Kawasaki case with the history of chicken's contact. The specimen was tested for all influenza subtypes especially H5N1 and the results were negative. Meanwhile PCR was done for screening of other respiratory viruses that results came out positive for RSV and hMPV. CONCLUSION In the present study, we demonstrated the possibility to detect dual infection caused by RSV and hMPV, but because of the extravagant pattern of this case, more investigation is suggested specially on Kawasaki patients.

Abstract
Kawasaki disease is a disease of unknown etiology that most frequently affects infants and children under 5 years of age. Inflammation occurs in medium-sized muscular arteries throughout the body including the coronary artery, being classified as a systemic vasculitis syndrome. Histopathological investigations of Kawasaki disease have mainly focused on the coronary artery because it is directly associated with the cause of death. However, to identify the cause and pathology of Kawasaki disease, it is necessary to investigate lesions of whole organs. Thus, we attempted to review lesions in organs other than the heart and hypotheses of pathogenesis recently attracting attention.

Abstract
BACKGROUND Kawasaki disease is an acute vasculitis that occurs mainly in children. Cervical lymphadenopathy is one of the major presenting manifestations of Kawasaki disease. We report a case of Kawasaki disease with para aortic lymphadenopathy, as an unusual feature in this disease. CASE PRESENTATION This 2.5 year old girl presented with persistent high grade fever, erythematous rash, bilateral non purulent conjunctivitis, red lips, and edema of extremities. Laboratory results included an elevated erythrocyte sedimentation rate, leukocytosis, anemia, and positive C-reactive protein. On second day after admission she developed abdominal pain. Ultrasonography of abdomen revealed multiple lymph nodes around para aortic area, the largest measuring 12mm×6mm. Treatment consisted of aspirin and high dose intravenous γ-globulin. Ultrasonography and CT scan of abdomen performed one week later showed disappearance of the lymph nodes. CONCLUSION There are few previous reports of lymphadenopathy in unusual sites such as mediastinum in Kawasaki disease. Para aortic lymph nodes enlargement might be an associated finding with acute phase of Kawasaki disease. In these patients a close observation and ultrasonographic follow up will prevent unnecessary further investigation.

Abstract
Background and Objectives The pathogenesis of hyponatremia (serum sodium <135 mEq/L) in Kawasaki disease (KD) remains unclear. We investigated the clinical significance of hyponatremia, and the role of interleukin (IL)-6 and IL-1β in the development of hyponatremia and syndrome of inappropriate antidiuretic hormone secretion (SIADH) in KD. Subjects and Methods Fifty KD patients were prospectively enrolled and analyzed for clinical and laboratory variables according to the presence of hyponatremia or SIADH. Results Thirteen KD patients (26%) had hyponatremia and 6 of these had SIADH. In patients with hyponatremia, the percentage of neutrophils (% neutrophils), C-reactive protein (CRP), and N-terminal pro-brain natriuretic peptide (NT-proBNP) were higher than in those without hyponatremia, while serum triiodothyronine (T3) and albumin were lower. Patients with hyponatremia had a higher incidence of intravenous immunoglobulin-resistance but this was not statistically significant. No differences existed between patients with and without SIADH with regard to clinical or laboratory variables and the incidence of IVIG-resistance. Serum sodium inversely correlated with % neutrophils, CRP, and NT-proBNP, and positively correlated with T3 and albumin. Serum IL-6 and IL-1β levels increased in KD patients and were higher in patients with hyponatremia. Plasma antidiuretic hormone increased in patients with SIADH, which tended to positively correlate with IL-6 and IL-1β levels. Conclusion Hyponatremia occurs in KD patients with severe inflammation, while increased IL-6 and IL-1β may activate ADH secretion, leading to SIADH and hyponatremia in KD.

Abstract
Background and Objectives This was a multicenter study to evaluate the usefulness of the tumor necrosis factor-alpha (TNF-α) blocker infliximab for treatment of Korean pediatric patients with refractory Kawasaki disease (KD). Subjects and Methods Data from 16 patients throughout Korea who were diagnosed with refractory KD and received infliximab were collected retrospectively. Results Complete response to therapy with cessation of fever occurred in 13 of 16 patients. C-reactive protein (CRP) concentrations decreased following infliximab infusion in all 14 patients in whom it was measured before and after treatment. There were no infusion reactions or complications associated with infliximab except in 1 case with acute hepatitis occurring during treatment followed by calculous cholecystitis 4 months later. Fifteen patients had coronary artery (CA) abnormalities before infliximab therapy. Three had transient mild dilatation and 9 had CA aneurysms, with subsequent normalization in 4 patients, persistent mild dilatation in 3, persistent aneurysm in 2, and there were 3 cases (2 with CA aneurysm, 1 with mild CA dilatation) without follow-up echocardiography. Conclusion The results of this study suggest that infliximab may be useful in the treatment of refractory KD, and it appears that there is no significant further progression of CA lesions developing after infliximab treatment. Multicenter trials with larger numbers of patients and long-term follow-up are necessary to assess the clinical efficacy and safety of infliximab in refractory KD.

Abstract
A 6-year-old girl, a known case of Kawasaki disease, presented with acute thrombotic occlusion of right coronary artery (RCA) with symptoms of acute angina and myocardial dysfunction. She underwent beating heart off-pump coronary artery bypass graft (CABG) surgery with right internal mammary artery (RIMA) grafted to distal RCA. Follow-up computed tomography angiogram revealed well-flowing RIMA with no obstruction or kink. This case highlights the importance of CABG as a safe and life-saving procedure in expert hands, even for children in emergent conditions.

Abstract
Cutaneous vasculitides in childhood are rare and often present with clinical features distinct from adults. Diagnosis of cutaneous vasculitides in children was difficult because of lack of a satisfactory classification systems for this age group. A new international classification system for childhood vasculitis has been discussed in the following section along with important clinical features, diagnostic modalities, and recent therapeutic developments of important vasculitides in children.

Abstract
Kawasaki disease (KD) is a leading cause of non-atherosclerotic coronary artery aneurysms and, less commonly, peripheral artery aneurysms. We report an 81-year-old Japanese man from Hawaii with a history of an abdominal aortic aneurysm, bilateral iliac aneurysms, and an ambiguous right atrial cystic mass. The patient developed new-onset atrial fibrillation during lithotripsy. Angiography and magnetic resonance imaging revealed giant coronary artery aneurysms of the right coronary artery (RCA) and left anterior descending artery, and a thoracic aortic aneurysm. The RCA aneurysm was greater than 2 inches in diameter at the time of operation. Although we cannot confirm whether the patient had KD during childhood, this is the most likely diagnosis in the absence of a connective tissue disorder, systemic vasculitis, or atherosclerotic risk factors. This patient may represent the oldest case of KD, predating the earliest known case by more than 20 years. This case sheds light on the historical epidemiology of KD and its clinical course, especially regarding late vascular sequelae.

Abstract
Background and Objectives High-dose intravenous immunoglobulin (IVIG) (2 g/kg) is usually given in the treatment of Kawasaki disease (KD). According to the authors' experience, however, medium-dose immunoglobulin (1 g/kg) was also effective in the majority of patients. We performed a retrospective clinical study to validate effectiveness of the medium-dose regimen in treatment of KD. Subjects and Methods A total of 274 patients with KD who were treated with medium-dose immunoglobulin at Bundang Jesaeng General Hospital from July 1998 to October 2007 were enrolled. Results Medium-dose immunoglobulin was given once in 220 patients (group A; 80.3%) and twice or more in 54 patients (group B; 19.7%). Age and gender distributions, duration of fever before treatment, hemoglobin concentrations, and white blood cell and platelet counts did not differ significantly between the two groups (p>0.05). Concentrations of C-reactive protein, aspartate aminotransferase, alanine aminotransferase, and bilirubin were significantly higher in group B (p<0.005). Coronary arterial lesions (CAL) were found in 51 patients (23.2%) in group A and in 26 patients (48.1%) in group B during the acute stage, and in 14 patients (6.4%) in group A and in 11 patients (20.4%) in group B during the convalescent stage (p<0.005, respectively). A giant aneurysm was found in one patient in each group (0.5% in group A and 1.9% in group B; p<0.005) during the follow-up period. Conclusion A single infusion of medium-dose immunoglobulin was effective in 80% of patients with KD. About 20% of patients required two or more infusions of medium-dose immunoglobulin, who had higher concentrations of C-reactive protein, aspartate aminotransferase, alanine aminotransferase and bilirubin. The authors think that the medium-dose regimen proffers an advantage over the high-dose regimen in view of cost-effectiveness.

Abstract
BACKGROUND Kawasaki disease (KD) is a common cause of acquired heart disease in children. Recent studies have focused on the biochemical markers of the myocardium, their high sensitivity and specificity and significance in the diagnosis of KD. This study aimed to determine the serum level of brain natriuretic peptide (BNP) and its relation with the heart function of children with KD and to explore its clinical value in diagnosis of KD. METHODS Forty-three KD children, aged from 5 months to 8 years (mean 2.3±0.6 years), were admitted to Qingdao Children's Hospital from February 2007 to April 2009. Among them 27 were male, and 16 female. The 43 patients served as a KD group. Patients with myocarditis, cardiomyopathy, congenital heart disease and other primary heart diseases were excluded. Thirty healthy children, aged from 3 months to 15 years (mean 2.5±0.8 years) or 17 males and 13 females served as a control group. There were no significant differences in age and gender between the two groups (P>0.05). In the KD group, ELISA was used to measure the levels of serum BNP in acute and convalescent stages; and in the control group, the levels of serum BNP were measured once randomly. Left ventricular ejection fraction (LVEF), left ventricular shorten fraction (LVSF), cardiac index (CI) and left ventricular inflow velocity through the mitral annulus (including E-velocity and A-velocity) were measured by two-dimensional echocardiography in the acute and convalescent stages in the KD group. All data were expressed as mean±SD. The methods of analysis included Student's t test and the linear regression analysis test. P<0.05 was considered statistically significant. RESULTS The level of serum BNP in the acute stage (517.26±213.40) ng/ml was significantly higher than that in the convalescent stage (91.56±47.97) ng/ml in the control group (37.55±7.56) ng/ml (P<0.01). The levels of LVEF, LVSF and CI in the acute stage were significantly lower than those in the convalescent stage (P<0.05), but the E/A level was not significantly different between the acute and convalescent stages (P>0.05). Linear regression analysis showed that the BNP level was negatively correlated with the levels of LVEF, LVSF and CI(r=-0.63, -0.52, -0.53, P<0.05), but not significantly correlated with the E/A level (r=-0.18, P>0.05). CONCLUSION The levels of serum BNP are significantly increased in KD patients, and are negatively correlated with the levels of LVEF, LVSF, and CI. The detection of serum BNP level is of clinical significance in the diagnosis of KD.

Abstract
A male infant aged 3 months and 1 week had persistently high fever with parotitis that was unresponsive to antibiotics. Mumps was identified by serologic study, but he was finally diagnosed by clinical features as having Kawasaki disease and echocardiographic findings on the 9th day of fever. Parotitis, which is unresponsive to antibiotics, should be considered Kawasaki disease even though typical symptoms are not present.

Abstract
PURPOSE Kawasaki disease is a systemic vasculitis, and its etiology and pathogenesis are still not clear. Our study was undertaken to investigate the characteristics of the activation of B cells in the peripheral blood of Kawasaki disease (KD) patients and evidence of stimulation by superantigens. MATERIALS AND METHODS Blood samples were obtained from three patients (2 males, 1 female) with KD, who were admitted to our Hospital, Seoul, Korea. The mean age was 1.2 years. Distribution of B cells was studied in the acute and subacute phases of KD patients. From the RNA of B cells, we obtained complementary DNA (cDNA) and performed polymerase chain reaction (PCR). To determine the oligoclonal expansion of immunoglobulin M (IgM) V(H) family, we cloned and sequenced the PCR products from each group and analyzed DNA. RESULTS In the peripheral blood of acute phase patients, T cells were significantly decreased (p < 0.05), whereas B cells were significantly increased (p < 0.05). When the first PCR was done on the B cell chains, V(H)1 to V(H)6 were all found to be expressed. The number of micro gene clones obtained from 3 patients was 312, and they belonged to V(H)3, V(H)4 and V(H)5 family. M99686 germ line was most frequently used and the next most frequently used, were X92224/J, L21967 and L21964. A similar order was seen in patients. Among the clones, 20 sets of clones showed the same base sequence and this was frequent between V(H)2 and V(H)5. There was one set, which showed almost the same base sequence between different patients, and the homology was 99.5%. Twenty sets of clones that had the same base sequence showed high similarity to the germ line (94 - 100%). Among these, the clones that utilized the M99686 germ line were 4 sets which were most frequent. The 3-dimensional structure of one of these clones showed typical beta, sheet structure of immunoglobulin chains. CONCLUSION The IgM transcripts expressed by the B cells in the peripheral blood of KD patients in the acute phase of the disease clearly showed an oligoclonal expansion, suggesting that KD is caused not by stimulation of a superantigen, but rather by a conventional antigen.

Abstract
Background and Objectives Kawasaki disease (KD) is an acute inflammatory process affecting the arterial walls that results in panvasculitis. Recent studies have shown that even after resolution of the disease, endothelial dysfunction persists and may progress to atherosclerosis. The pulse wave velocity (PWV) and the ankle-brachial index (ABI) are simple and non-invasive methods for evaluating the degree of atherosclerosis, and are known as the predictors of cardiovascular disease in adults. Carotid intima-media thickness (cIMT) is also known as a predictor of cardiovascular disease. We conducted this study to determine the change in arterial stiffness by measuring the PWV, ABI, and cIMT in children who have recovered from KD. Subjects and Methods Twenty-five patients with KD and coronary aneurysm were recruited. They all recovered from KD and were normal for more than 8 years. Fifty-five healthy children were evaluated as the control group. Their height, weight, body mass index, and blood pressure (systolic, diastolic, and the mean) were measured. The PWV, ABI, ejection time (ET), and pre-ejection period (PEP) were measured by ultrasonography. The cIMT was measured by ultrasonography. Results The left brachial ankle PWV was significantly higher in the KD group (1020.6±146.5 cm/sec) than the control group (984.0±96.5 cm/sec). The ABI did not differ between the two groups. There was no difference in PEP/ET and cIMT. Conclusion The PWV in children who recovered from KD was higher than the control group. Long-term follow up is necessary in children after recovery from KD even if there is no abnormality in echocardiography.

Abstract
OBJECTIVES To describe the clinical features, diagnosis, treatment and outcome of children with Kawasaki disease (KD) treated at a large tertiary care Canadian paediatric hospital and to try to identify correlations between clinical features and the development of coronary artery abnormalities. METHODS The charts of 176 patients diagnosed with typical, atypical or incomplete KD between 1992 and 2000 at British Columbia's Children's Hospital were reviewed. RESULTS The male to female ratio was 1.8:1. The median age was 2.5 years (range two months to 14 years), with 8% nine years or older (42% Caucasian, 43% Asian). Cases occurred steadily throughout the year. One hundred two (58%) patients had typical, 18 (10%) patients had atypical and 56 (32%) patients had incomplete KD. The median time from fever onset to first intravenous immunoglobulin (IVIG) was seven days (range two to 49 days), and treatment began within 10 days of fever onset in 134 (76%) patients. All patients received one or more doses of 2 g/kg IVIG. Forty-two (24%) patients received a second dose for nonresponsiveness, of whom 10 (6%) remained nonresponsive. Eight (5%) patients received intravenous methylprednisolone. Forty-eight (27%) patients developed coronary artery abnormalities, with 10 (6%) echogenic abnormalities, 25 (14%) dilatations and 13 (7%) aneurysms (seven giant). No patient with a normal echocardiogram at four to eight weeks developed an abnormality on subsequent study. Fourteen (8%) patients had persistent abnormalities at last follow-up (median 447 days, range 62 to 3272 days): seven dilations and seven aneurysms (six giant). Five of 13 children (39%) who developed aneurysms failed to meet diagnostic criteria for typical KD, and three of those five aneurysms were present at less than one year after diagnosis. Four of eight (50%) patients receiving intravenous methyl-prednisolone for IVIG nonresponsiveness had or developed aneurysms. One patient died. CONCLUSION Some children diagnosed with KD who fail to meet the diagnostic description develop coronary artery abnormalities. There is a need for a more accurate means of diagnosis to more appropriately use IVIG, an expensive and increasingly scarce resource. The role of corticosteroids remains unclear and a randomized controlled clinical trial to determine their role is needed.
