Abstract
Kawasaki disease (KD) is a common vasculitic disorder of childhood. Reported mortality in KD in Japan is 0.014%. We report the clinical and laboratory profile of 4 children who succumbed to KD during the period January 1994 to March 2015 at the Paediatric Allergy Immunology Unit, Advanced Paediatrics Centre, Post Graduate Institute of Medical Education and Research Centre, Chandigarh, India. A total of 460 children were diagnosed with KD based on the American Heart Association criteria. Male to female ratio was 1.96:1 and 106 children were aged 2 years or less. Children with KD received 2 g/kg of intravenous immunoglobulin (IVIg). In addition, aspirin was administered in doses of 30-50 mg/kg/day during the acute phase and 3-5 mg/kg/day thereafter. 2-D echocardiography was carried out once during the acute phase and approximately 6-8 weeks later on follow-up. Four children (2 boys, 2 girls) died during this period and their details were analysed from their clinical records. All 4 were under 2 years of age and had had significant delays in diagnosis and referral. Symptomatic myocarditis was noted in 2 children, while 2 of them had thrombocytopenia. We report a mortality of 0.87% in children with KD. Delays in diagnosis and referral contributed significantly to this mortality. To the best of our knowledge, this is the first report on mortality in KD from any developing nation.

Abstract
AIM To describe the patient characteristics, management and cardiovascular sequelae of Kawasaki disease (KD) in patients taking part in a multidisciplinary follow-up in the Emma Children's Hospital during the period January 1999-June 2010. DESIGN Retrospective, observational study. METHODS We included 392 patients who were diagnosed with complete or incomplete KD. Clinical and outpatient statuses were used to collect clinical data. RESULTS The median age at onset of the disease was 3.2 years (range: 0.1-16.4). The male-to-female ratio was 1.6 : 1. Complete KD was diagnosed in 83.9% of patients. Patients with incomplete KD were younger than those with complete KD: 2.2 versus 3.4 years (both SD: 3.0; p < 0.01). 357 patients (91.1%) were treated with intravenous immunoglobulins; 65 patients (16.6%) received a second intravenous dose. Coronary artery aneurysms were diagnosed in 83 patients (21.2%). Male gender, age < 1 year, incomplete presentation and late start of treatment (> 10 days after start of fever) were shown to be independent risk factors for developing aneurysms. These abnormalities normalized in 50 of the 83 patients. 2 patients died of the disease within a year. 5 patients underwent coronary artery bypass grafting during the follow-up period. CONCLUSION Kawasaki disease is a rare form of vasculitis seen in children, in which aneurysms of the coronary artery can develop. Clinicians should be alert to the possibility of KD in cases of persistent inexplicable fever, especially in young children, even in the absence of complete clinical disease. A timely start to treatment reduces the risk of developing coronary artery aneurysms.

Abstract
Kawasaki disease (KD) was first reported from Japan in 1967 by a young pediatrician, Tomisaku Kawasaki, while working at the Red Cross Hospital in Tokyo. Soon therafter, Marian Melish independently reported children with a similar clinical profile from Hawaii in the United States. KD has now been reported from all parts of the world, including several centers in India. Based on the epidemiology and clinical features, an infectious etiology has been suspected for long but no definitive causative agent has been implicated so far. Like many other vasculitides, the diagnosis of this condition is based on the recognition of a temporal sequence of clinical features, none of which is pathognomonic in isolation. KD is believed to be the commonest vasculitic disorder of children. Incidence rates as high as 60-150 per 100,000 children below 5 years of age have been reported from several countries. In India (as also perhaps in many other developing countries), however, majority of children with KD continue to remain undiagnosed probably because of the lack of awareness amongst pediatricians. The clinical features of KD can be confused with other common conditions like scarlet fever and the Stevens Johnson syndrome, if the clinician is not careful. Development of coronary artery abnormalities (CAA) is the hallmark of KD and accounts for most of the morbidity and mortality associated with the disease. Prompt recognition of the disease and early initiation of treatment with intravenous immunoglobulin (IVIG) results in significant reduction in the occurrence of CAA. It is, therefore, imperative for the pediatrician to diagnose and treat KD expeditiously. KD should be considered in the differential diagnosis of all febrile illnesses in young children where the fever persists for more than 5-7 days.

Abstract
The 20-year clinical outcome is excellent for the children with Kawasaki disease who underwent a bypass operation using the internal thoracic artery. This operation is feasible from 1 year-old children and in our experience with more than 110 patients, the operative and hospital mortality was 0%, and the 20-year survival was 98.4%. The recent patency rate was nearly 95% for the internal thoracic artery graft regardless of the patient's age, and the 20-year patency was 87.1%. Moreover, the wall characteristics of the internal thoracic artery was quite smooth and apparently well adapting to the somatic growth of children over 20 years after the operation. In contrast, vein grafts had a lower patency of 57% at 20 years. In addition, patent vein grafts showed irregularity of the wall and in some, atherosclerotic changes were observed. Pediatric coronary bypass operation utilizing the internal thoracic artery is proved to be a golden standard treatment modality for complicated coronary artery obstructive disease due to Kawasaki disease, based upon the 20-year clinical and angiographic follow-ups.

Abstract
AIM We conducted a prospective study to evaluate the causes and outcome in children with fever of unknown origin (FUO). METHODS From 1990 to 1999, 185 children with FUO were evaluated. Initial evaluation included routine haematological analysis, Epstein-Barr virus (EBV) serology, urine, stool or blood cultures, chest X-ray and tuberculin probe. RESULTS In 131 (70%) patients diagnosis was established, and 70 (37.8%) had infectious disease. EBV infection was the most common infection followed by visceral leishmaniasis (VL), urinary tract infection (UTI) and tuberculosis. Autoimmune disorders were diagnosed in 24 (12.9%), Kawasaki disease in 12 (6.4%), malignant diseases in 12 (6.4%) and miscellaneous conditions in 15 (8.1%) patients. In the remaining 54 (30%) patients, diagnosis was not established and most of them had self-limited disease. During the investigation, 26 (14%) patients developed serious organ dysfunction and five patients (two with virus-associated haemophagocytic syndrome, one with VL and two unknown) died. CONCLUSION The most important infectious causes of FUO in our study were EBV infection and VL. Kawasaki disease represented a significant cause of FUO at the beginning of our study because it was not recognized by primary-care physicians. We report myelodysplastic syndrome as another emerging cause of paediatric FUO. Repeated clinical examination and careful use of specific laboratory examinations, invasive diagnostic procedures or imaging are crucial in approaching paediatric FUO.

Abstract
Angiogenesis has been shown to be dysregulated in coronary artery (CA) aneurysms in the chronic phase of Kawasaki disease (KD). Neovascularization may occur in inflammatory-related vascular diseases because many angiogenesis mediators are secreted by inflammatory cells. We hypothesized that inflammation of the acute KD CA aneurysm could lead to dysregulation of angiogenesis mediators and subsequent neovascularization. To investigate this hypothesis, acute fatal KD cardiac tissues were immunostained for angiogenic inducers and inhibitors. Microvessel density was determined and the degree of inflammation assessed. Marked inflammation and angiogenesis were found in acute KD CA aneurysms and myocardium, with the highest microvessel density seen in patients who died 2-3 weeks after onset of the disease. Expression of proangiogenic proteins was higher than expression of inhibitors in KD CA aneurysms and myocardium. Angiogenesis mediators were localized to inflammatory cells in the myointima, adventitia, and myocardium. We conclude that significant neovascularization occurs in acute KD CA aneurysms and myocardium much sooner after onset of the disease than has been previously reported, that multiple angiogenesis factors are involved, and that dysregulation of angiogenesis likely contributes to KD vasculopathy.

Abstract
BACKGROUND There has been no morphological evidence that polymorphonuclear leukocytes (PMNL) infiltrate the coronary arterial lesions of acute Kawasaki disease (KD) patients, although clinical data indicate the activation of PMNL. METHODS The experimental materials consisted of eight autopsy patients who died during the acute phase of KD. Duration of the illness ranged from 6 to 32 days. The tissues were fixed and embedded in paraffin. Hematoxylin and eosin, elastica van Gieson and azan-Mallory stainings were performed for routine histological examination. In addition, antibodies to CD3, CD20, CD68 and neutrophil elastase were used for immunohistochemistry to identify infiltrating cells in arterial lesions. RESULTS The inflammatory cells that appeared in the coronary arterial lesions were mainly composed of macrophages in all patients. In addition, numerous neutrophils were also identified in the coronary arterial lesions of the patients who died 10 days after the onset of KD. Neutrophilic infiltration reached a peak earlier than the peaks of CD68+ macrophages, CD3+ T lymphocytes and CD20+ B lymphocytes. CONCLUSIONS These results suggest that neutrophils are involved in the damage occurring to coronary arteries in the early stage of KD. Vasodilation might occur as a result of injury to vascular walls caused by neutrophils, as well as macrophages.

Abstract
Kawasaki disease (KD) is the leading cause of acquired pediatric heart disease in North America and Japan. Cardiac sequelae, such as coronary artery aneurysms and myocardial infarction, are the major causes of the morbidity and mortality associated with KD. Three case scenarios are described illustrating the wide range of clinical presentations of myocardial ischemia in children after acute KD, varying from asymptomatic to fatal myocardial infarction. In addition, the present paper provides a review of the literature on myocardial infarction in association with KD and various modalities of coronary artery revascularization in children with myocardial ischemia secondary to KD.

Abstract
AIM To clarify the question of whether patients with Kawasaki disease suffer a higher mortality rate after the incidence of the disease in comparison with age-matched healthy individuals. METHODS Between July 1982 and December 1992, 52 collaborating hospitals collected data on all patients having a new, definite diagnosis of Kawasaki disease. Patients were followed up until 31 December 2001 or their death. The expected number of deaths was calculated from Japanese vital statistics data and compared with the observed number. RESULTS Of 6576 patients enrolled, 29 (20 males and 9 females) died. The standardized mortality ratio (SMR: the observed number of deaths divided by the expected number of deaths based on the vital statistics in Japan) was 1.15 (95% CI: 0.77-1.66). In spite of the high SMRs during the acute phase, the mortality rate was not high after the acute phase for the entire group of patients. Although the SMR after the acute phase was 0.75 for those without cardiac sequelae, six males (but none of the females) with cardiac sequelae died during this period; and the SMR for the male group with cardiac sequelae was 1.95 (95% CI: 0.71-4.25). The mortality from congenital anomalies of the circulatory system was elevated, but no increase in cancer deaths was observed. CONCLUSION Although it was not statistically significant, the mortality rate among males with cardiac sequelae due to Kawasaki disease appeared to be higher than in the general population. On the other hand, the mortality rates for females with the sequelae and both males and females without sequelae were not elevated.

Abstract
Coronary arterial inflammation in acute Kawasaki disease (KD) is characterized by transmural infiltration of CD8 T lymphocytes, suggesting that CD8 T lymphocyte cytotoxic activity may be important in the pathogenesis of coronary arterial damage in acute KD. We performed immunohistochemistry for the cytotoxic proteins perforin and granzyme B on paraffin-embedded, formalin-fixed coronary artery aneurysm tissue from 6 children who died in the acute stage of KD. Neither perforin nor granzyme B was detected in the KD coronary aneurysm wall. We speculate that the etiologic agent of KD interferes with expression of these cytotoxic proteins by CD8 T lymphocytes, prolonging inflammation in the arterial wall and leading to coronary artery aneurysm formation.

Abstract
BACKGROUND Chronological changes in mortality and case fatality rates from Kawasaki disease covering an extended period in Japan are still unknown. METHODS We analyzed 679 deaths of patients in Japan whose underlying cause was Kawasaki disease, by using the data of vital statistics between 1972 and 1998. RESULTS The male-to-female ratio of the number of deaths was 2.07 and the mean age at death in males was higher. Two unusual increases in the epidemic years, 1982 and 1986, were observed in the chronological changes of the number of deaths. The mortality rate of males was higher than that of females, with a few exceptional years, and the annual mortality rates were high in three epidemic years. The age-specific mortality rate was highest in infants under one year of age. Prefectures with high mortality rate clustered in some regions. The case fatality rate decreased annually, declining to as low as 0.2% among those who were born in 1986 and thereafter; and unusual increases in the case fatality rate affected by these three epidemic years were not repeated. CONCLUSIONS The case fatality rate from Kawasaki disease in Japan decreased during the 27 years of observation: improvements in treatment might account for this.

Abstract
BACKGROUND Early stage Kawasaki disease (KD) histopathology includes perivasculitis and vasculitis of the microvessels. The lesions then extend to larger vessels. Therefore the analysis of microvessel lesions is important to better understand the initial pathogenesis of KD vasculitis. METHODS AND RESULTS We studied epicardial microvessel lesions (<50 microm) and aneurysm lesions of paraffin-embedded cardiac tissues from 4 Japanese patients who died 7 to 22 days after KD onset. The cellular composition in the microvessel lesions was different from that in coronary aneurysm lesions; eosinophils were preferentially accumulated in the microvessel lesions. The average population of eosinophils was 16% of total infiltrated cells in the microvessel lesions, whereas it was 3% in the intima of aneurysm walls. We examined peripheral blood eosinophil cell counts in 95 KD patients and 95 febrile age-matched controls. Baseline eosinophil cell counts in KD patients were higher than those in febrile control patients (361 +/- 441 65 +/- 133; < 0.0001). Eosinophilia (>350 cells/microl) before therapy was documented in 36% of KD patients, but in only 4% of febrile controls ( < 0.0001). Sixty-six KD patients (69%) developed eosinophilia within 2 weeks of illness. CONCLUSIONS Because the numbers of circulating eosinophils in the body are tightly regulated, eosinophil accumulation in blood or tissues may reflect the host's immune response against KD related antigen(s).

Abstract
OBJECTIVE To determine whether patients with Kawasaki disease have a higher death rate than an age-matched healthy population after disease occurrence. STUDY DESIGN From July 1, 1982, to December 31, 1992, 52 collaborating hospitals collected data on all patients with a new definite diagnosis of Kawasaki disease. Patients were followed up until December 31, 1999, or death. The expected number of deaths was calculated from Japanese vital statistics data and compared with the observed number. RESULTS Of 6576 patients enrolled, 27 (19 male, 8 female) died. The standardized mortality ratio (the observed number of deaths divided by the expected number of deaths based on the vital statistics in Japan) was 1.25 (95% confidence interval, 0.84-1.85). Despite the high standardized mortality ratios during the acute disease phase, the mortality rate was not high after the acute phase for the entire group of patients. Although the standardized mortality ratio after the acute phase was 0.76 for those without cardiac sequelae, 6 male patients (no female patients) with cardiac sequelae died during this period, and the standardized mortality ratio for the male group with cardiac sequelae was 2.35 (95% confidence interval, 0.96-5.19). CONCLUSIONS Although it was not statistically significant, the mortality rate among male patients with cardiac sequelae due to Kawasaki disease seemed higher than that in the general population. On the other hand, mortality rates for female patients with sequelae and both male and female patients without sequelae were not elevated.

Abstract
The objective of this paper is to describe the epidemiological and clinical characteristics of Kawasaki disease (KD) in Shaanxi Province, China during the 5-year period from January 1993 to December 1997. A province-wide epidemiological survey on KD was made by the China-Japan Kawasaki Disease Study Group. The questionnaire form and the diagnostic criteria of KD, which were prepared by the Japan Kawasaki Disease Research Committee and translated into Chinese, were sent to the departments of pediatrics of all the hospitals with 100 beds or more in Shaanxi province. All the KD patients who were diagnosed during the observation period from 1993 to 1997 were asked to take part in this survey. The databases of reported KD in this survey were analysed at the Department of Pediatrics of the Shaanxi Provincial People's Hospital, Xi'an, China. All the patients that satisfied the diagnostic criteria were included in the report. A total of 105 (70 per cent) hospitals responded and 376 cases of KD were confirmed. More cases were reported in 1993 and 1994. Of the total patients reported, 69 per cent were children under 3 years old with a male to female ratio of 1.6:1. The proportion of patients with cardiac sequelae was 19 per cent with a male to female ratio of 3:1. There were four fatal cases with a fatality rate of 1 per cent. It is concluded that KD is common in China. Continuous surveillance is necessary to maintain high awareness of KD so as to find possible risk factors and their association with the disease.

Abstract
BACKGROUND Pediatric coronary artery bypass (PCAB) has been recently employed for expanding indications to treat acquired, congenital, post arterial switch, and other iatrogenic pediatric coronary artery problems. METHODS Between 1987 and 1998, 3 infants and 13 children (n = 16, mean age 6.1 years, range 2 months-18 years) underwent one or more internal thoracic artery (ITA) to coronary artery (CA) bypass grafts for Kawasaki disease (n = 4), congenital lesions (n = 3), post arterial switch (n = 4), and other iatrogenic obstructions (n = 5). Proximal left main CA arterioplasty was performed concurrently with ITA-CA bypass in 4 patients. RESULTS Survival is 93.8%. All bypass grafts in surviving patients are patent 2 months-11 years postoperation. The 11 elective patients are well (NYHA I-II). The 5 emergent operations were performed in 2 infants and 3 adolescents who had poor ventricular function prior to ITA-CA bypass due to iatrogenic injuries in 3, congenital critical left main stenosis in 1, and intraoperative iatrogenic coronary injury in 1. The 3 adolescents fared worse, resulting in death in the first, cardiac transplantation in the second, and full recovery in the third. The 2 infants have steadily improving ventricular function. CONCLUSIONS ITA-CA bypass can be successfully performed in infants and children for expanding elective and life-saving indications with excellent results. Poor preoperative ventricular function often persists, especially in those older children with iatrogenic injuries, and may result in death or cardiac transplantation.

Abstract
Kawasaki disease (KD) is an acute febrile illness of childhood of unknown origin which causes an arteritis of small and medium sized arteries. The arteritis may involve any organ, including the coronary arteries, causing diffuse dilatation, aneurysm formation, stenosis, infarction and death. This paper determines the incidence of KD in Malta and compares the incidence and morbidity of KD in Malta with that in other countries. The Maltese incidence is 3.2/100,000 population < 5 years of age, similar to that reported in non-Asiatic communities, and significantly less than that reported in Asiatic communities. None of the Maltese patients had coronary arteritis or other complications. A significant decline in delay to diagnosis was found, which is attributed to increased awareness of the disease in the medical community.

Abstract
OBJECTIVE The objective of the study is to describe recent epidemiologic patterns of Kawasaki disease based on information included in patient records that had been obtained through a nationwide hospital survey in Japan. METHODS A questionnaire and diagnostic criteria for Kawasaki disease that had been approved by the Kawasaki Disease Research Committee were sent to all pediatric departments of hospitals (2638 hospitals) with a bed capacity of at least 100. The subjects all were new patients who were treated during a 2-year period from 1995 to 1996. RESULTS A total of 12 531 children contracted the disease during the observation period. The incidence was 102.6 for 1995 and 108.0 for 1996 per 100 000 children younger than age 5 years. The male:female ratio was 1.37. The age distribution pattern showed a peak near 6 months of age. Geographic variations in the incidence suggested the existence of local outbreaks. Cardiac sequelae were seen in 12% of the patients. CONCLUSION More than 6000 patients suffered from Kawasaki disease each year, and its annual incidence is increasing steadily. The probable existence of local outbreaks is worthy of note. Other epidemiologic patterns were unchanged from previous years.

Abstract
BACKGROUND Long-term prognosis of Kawasaki disease is still unclear. METHODS In a cohort study, 6576 patients with Kawasaki disease were observed from their first medical encounter because of the disease through the end of 1994, or until death. Standardized mortality ratios (SMR) with 95% confidence intervals (CI) were calculated with vital statistics data of Japan used for the control. RESULTS Of 6576 patients who met the eligibility criteria, 6550 (99.6%) were followed through either the end of the study or the date of death. Twenty patients (14 male, 6 female subjects) died during the study period; an overall SMR of 1.35 (95% CI 0.82-2.08) was calculated. The SMR was 1.45 (95% CI 0.79-2.44) for male subjects and 1.15 (95% CI 0.42-2.52) for female subjects. During the acute phase of the disease (the first 2 months after the first visit to hospital), the SMR was higher, particularly in male subjects (SMR 10.13, 95% CI 3.72-22.08). After the acute phase, however, both boys and girls had low SMR. Nine of the 20 deaths were caused by Kawasaki disease; there were three deaths as a result of congenital heart diseases and two subjects died of malignant neoplasms of lymphatic or hematopoietic tissues. CONCLUSIONS Although the mortality rate among those with a history of Kawasaki disease was elevated in Japan, many of the deaths that caused the elevation occurred during the acute phase of the disease. The mortality rate was not increased after the acute phase of the disease.

OBJECTIVE The objective of this article is to describe the epidemiologic pictures of Kawasaki disease(KD) in Japan during the 2-year period of 1993 and 1994 based on the data obtained by the thirteenth nationwide epidemiologic survey of KD which was conducted by the Japan Kawasaki Disease Research Committee. METHODS A survey form and diagnostic criteria of KD were sent to all hospital pediatric departments (2,640) throughout Japan with 100 or more beds. The patients to be reported in this surveys were all the incident KD cases who satisfied the diagnostic criteria. RESULTS (1) A total of 1,730 (65.5%) hospitals responded, reporting 11,458(5,389 in 1993 and 6,069 in 1994; 6,729 males and 4,729 females; male/female ratio = 1.42) with an incidence rate of 95.1 per 100,000 children of age < 5 years. (2) The monthly number of patients was higher in winter and summer, although the monthly difference was not marked. (3) Age specific incidence rates showed a uni-modal peak at one year of age. (4) The proportion of patients with family history of KD in sibling was 1%. (5) The proportion of recurrent patients was 3%. (6) The proportion of patients with cardiac sequelae in one month after disease onset was 13%. (7) Number of fatal patients reported was 9, which conforms to 0.08% of total patients.

Abstract
OBJECTIVE To determine whether the mortality rate of patients with a history of Kawasaki disease is higher than that of the general population. DESIGN In a cohort study, 6585 patients with Kawasaki disease were observed from the first medical encounter because of the disease through the end of 1992, or until death. Standardized mortality ratios (SMRs) with 95% confidence intervals (CI) were calculated with vital statistics data of Japan for the control. RESULTS Of 6585 patients who met the eligibility criteria, 6550 (99.5%) were followed through either the end of the study or the date of death. Nineteen patients (14 male subjects) died during the study period; an overall SMR of 1.56 (955 CI, 0.94 to 2.43) was calculated for the entire study period. The SMR was 1.78 (95% CI, 0.97 to 2.99) for male subjects and 1.16 (95% CI, 0.38 to 2.71) for female subjects. During the acute phase of the disease (the first 2 months after onset), the SMR was higher, particularly in male subjects (SMR, 10.12; 95% CI, 3.72 to 22.07). After the acute phase, however, both boys and girls had low SMRs. Nine of the 19 deaths were caused by Kawasaki disease; there were 2 deaths as a result of congenital anomalies of the circulatory system and 2 subjects died of malignant neoplasms of lymphatic or hematopoietic tissues. CONCLUSIONS Although the mortality rate among those with a history of Kawasaki disease was elevated in Japan, many of the deaths that caused the elevation occurred during the acute phase of the disease. The mortality rate was not increased after the acute phase of the disease.

Abstract
OBJECTIVE To describe the long-term trend of incidence and other epidemiological pictures of Kawasaki disease in Japan, by using the results of 12 nationwide epidemiological surveys on Kawasaki disease that have been conducted throughout Japan (ie, surveys that have encompassed the pediatric departments of hospitals with more than 100 beds) every 2 years since 1970. RESULTS At the end of December 1992, the total number of patients with this disease was 116,848 (males, 67,815; females, 49,033; male-female ratio, 1.38). The number of cases increased year by year, with three outbreaks in 1979, 1982, and 1986. There have been no cyclical changes since 1986. The incidence was higher in males and in those children who were 1 year of age or younger. The fatality rate decreased from 1% in 1974 to 0.04% in 1992. CONCLUSIONS The patterns of descriptive epidemiology, such as seasonality and cyclical changes in incidence, supported the theory of an infectious agent as the causal agent. However, the incidence data since 1986 provide less support for an infectious theory.

Abstract
OBJECTIVE Since 1970, twelve nationwide epidemiologic surveys of Kawasaki disease (KD) have been conducted throughout Japan every two years to describe KD in Japan. By the end of 1992, a total of 116,848 cases were reported. This paper summarizes the statistical analysis of the latest survey for the 2-year period from January 1991 through December 1992. METHOD A questionnaire form and diagnostic guidelines for KD were sent to all pediatric departments of hospitals with 100 or more beds throughout Japan and information was obtained on patients with KD diagnosed during the 2-year period from January 1991 through December 1992. RESULTS The summary of the results is: 1) the number of patients reported was 11,221 (6604 males and 4617 females; male/female ratio = 1.43) with a yearly incidence rate of 90 per 100,000 children < 5 years old; 2) the monthly number of patients was higher in winter and summer, although the monthly difference was not marked; 3) age-specific incidence rates showed a unimodal peak at 1 year of age; 4) the proportion of patients with a family history of KD in a sibling was 1%; 5) the proportion of recurrent patients was 3%; 6) the proportion of patients with cardiac sequelae 1 month after disease onset was 13%; and 7) the number of patients who died was 9, which conforms to 0.08% of total patients. CONCLUSION The incidence rates of KD in Japan are ten times higher than those reported in western countries and almost constant over 6 years. The descriptive epidemiology of the disease, which supports the infection theory, does not change for years.

Abstract
Kawasaki disease in the British Isles was surveyed by an active reporting scheme, based on all cases reported to the British Paediatric Surveillance Unit that were diagnosed between 1 January and 31 December 1990. The study was prompted by the need to investigate the high case fatality rate of Kawasaki disease of 2% observed in 1988. One hundred and sixty three patients were identified of whom six (3.7%) died. Forty five children (28%) suffered cardiac complications of which 39 (24%) were coronary artery abnormalities; five children were diagnosed at postmortem examination, and coronary artery abnormalities were detected by echocardiography in 34. One hundred and forty nine children (93%) had echocardiography. High thrombocytosis, leucocytosis, duration of fever, and younger age were associated with the presence of coronary artery abnormalities. Erythrocyte sedimentation rate, sex, and the number of diagnostic criteria were not. One hundred and thirty three children (87%) received aspirin. Ninety three children (61%) received intravenous gammaglobulin (IVGG). Children were more likely to receive IVGG if they had thrombocytosis or typical Kawasaki disease. The incidence of coronary artery abnormalities was found to be similar in those treated with IVGG (29%) and those untreated (20%), including those treated within 10 days of onset. This may have reflected selection of the more serious cases to receive IVGG or that Kawasaki disease in the British Isles is a different illness to that experienced elsewhere. It amy be, however, that IVGG is less effective in the treatment of British patients with Kawasaki disease than has been the experience in the United States and Japan. These observations emphasise the need for a therapeutic trial of treatment modalities for Kawasaki disease in the UK and the Republic of Ireland.

Abstract
BACKGROUND AND METHODS It is not certain whether patients with Kawasaki disease have a higher death rate than the age-matched healthy population. We therefore undertook a study to investigate this question. Between July 1982 and December 1988, 53 collaborating treatment centers collected data on all patients who had an unequivocal new diagnosis of Kawasaki disease; patients who had recurrent disease or whose first visit to the treatment center occurred more than 14 days after the onset of symptoms were excluded. Patients were followed from the time of the first visit to the treatment center until December 31, 1989, or until death, whichever occurred first. The expected number of deaths was calculated from Japanese vital-statistics data and compared with the number observed. RESULTS Of 4676 patients who met the eligibility criteria, 4608 (98.5 percent) were followed through either the end of the study or the date of death. Thirteen patients (10 boys and 3 girls) died during the study period. The number of deaths expected was 7.61 (ratio of observed to expected deaths, 1.71; 95 percent confidence interval, 0.91 to 2.92). The ratio was 2.04 (95 percent confidence interval, 0.98 to 3.76) for boys and 1.11 (95 percent confidence interval, 0.23 to 3.23) for girls. During the acute phase of the disease (the first two months after onset), the ratios of observed to expected deaths were higher: 9.86 overall (95 percent confidence interval, 3.95 to 20.31), 13.33 for boys (95 percent confidence interval, 4.89 to 29.07), and 3.85 for girls (95 percent confidence interval, 0.10 to 21.42). After the acute phase, however, both sexes had ratios of observed to expected deaths that were lower than 1, and the difference from the control population was not statistically significant. CONCLUSIONS The mortality rate among boys with Kawasaki disease in Japan is twice that among healthy boys of the same age, and most deaths occur within two months of diagnosis. The mortality rate among girls with the disease appears similar to that among healthy girls, although the numbers are very small.

Abstract
Records of 34 children diagnosed as having Kawasaki disease in the Auckland region from 1979 to 1988 inclusive were reviewed. Diagnostic and associated features were similar to those reported from North America and Japan. The incidence (average 5.1 per year per 100,000 less than 5 years of age) was similar to that reported in Europe and North America amongst nonorientals and was similar in Polynesians and nonPolynesians. Coronary artery abnormalities were found in five cases (15%), and two cases, both of whom presented before five months of age, died. Those with abnormal coronary arteries had fever for a significantly longer period than those with normal coronary arteries.

Abstract
The heart and conduction system were studied in a 4 1/2-year-old boy with Kawasaki disease who died suddenly in the early phase of illness. Severe perivasculitis, neuritis, pancarditis, and involvement of all parts of the specialized conduction system were found. The boy's brother, born a year later, at the age of 12 months had relapsing Kawasaki disease. He received intravenous gamma globulin and recovered.

Abstract
Both immediate and long-term prognosis of Kawasaki's disease (K. D.) are due to cardiac involvement and, particularly, to coronary artery aneurysms formation. Of 19 cases that we studied, age ranging between 7 months and 8 years, 18 has been followed clinically and with echocardiographic procedure. In 1 case (10 years old), which underwent a triple bypass surgical operation due to the presence of multiple aneurysms, diagnosis was made retrospectively. In 2 of 19 cases (10.52%) coronary artery aneurysms were present. One case showed aneurysm's partial regression two years later. In 10 of 18 cases (55.5%) clinical evidence of cardiac compromise was present, whereas in no patient ECG alterations occurred at all. Our data prove the poor benefit of clinical approach and ECG interpretation in K. D., whereas we believe that echocardiographic study is the best method in early identification of aneurysms.

Abstract
We report an unselected series of eight patients younger than 6 months of age with Kawasaki disease evaluated between January 1982 and May 1984. The incidence of coronary artery aneurysms (six patients) and the mortality (two patients) were unusually high in this small series. Because of the confusing clinical presentation in three patients, diagnosis was delayed until pathologic or echocardiographic evidence of coronary vasculitis or aneurysm was discovered. The currently accepted clinical criteria for Kawasaki disease may not always identify patients with the pathologic findings of the syndrome who are younger than 6 months of age. The diagnosis of Kawasaki disease and echocardiographic evaluation of the coronary arteries should be considered in young infants with prolonged fever of unknown origin.

Abstract
Three dramatic clinical syndromes have been compared and contrasted. Of these, staphylococcal scalded syndrome is most readily recognized and least likely to have a morbid or fatal outcome. It is easy to confuse toxic shock syndrome and Kawasaki disease. Since the case fatality rate is significant in both of these diseases, and the management so different, proper recognition of the disease by its external features is critical.

Abstract
Death occurs in a small but significant percentage of patients with Kawasaki syndrome. Cardiovascular involvement is the major cause of death, which may be delayed and sudden. Much has been written about diagnosis and medical and surgical therapy. We reviewed the current understanding of this disease and its cardiovascular manifestations and offer a diagnostic and therapeutic protocol based on this review.

Abstract
Information about 261 cases of Kawasaki disease (KD) was reported to the Center for Disease Control (CDC) between July 1976 and July 1978. KD occurred at all times of the year in young, previously healthy children throughout the United States. KD was more common in infants and toddlers, males, and Asian and part-Asian children. The illness was characterized by acute onset of prolonged high fever; maculopapular or scarlatiniform rash; adenopathy; injection of the conjunctival and mucous membranes of the upper respiratory tract; redness of the palms and soles; indurative edema of the extremities; desquamation, arthralgias; and elevated white blood cell count, erythrocyte sedimentation rate, and platelet count. Complications included gallbladder disease and carditis; 2.8% died. Surviving patients were hospitalized for a mean of 8.9 days.

Abstract
A 12 year old boy had 4 symptom-free years after hospitalization for acute febrile mucocutaneous lymph node syndrome before he died suddenly from extensive myocardial infarction. Current evidence suggests that many patients with this syndrome have coronary artery disease and that those with significant cardiac findings should be studied with coronary angiography. Serial studies are recommended because of the danger of sudden death.

Abstract
Coronary artery aneurysm in childhood is a rare disease and has in most cases been ascribed to infantile periarteritis nodosa (IPN). In recent years a mucocutaneous lymph node syndrom (MLNS) has been found almost exclusively in Japan first described by Kawasaki 1967; this disease frequently involves the coronary arteries and myocardium. Four cases with coronary aneurysms are presented from Sweden and seem to be first described from Scandinavia. Three of these patients died a sudden death with cardiac arrest. Since MLNS and IPN have identical clinical and pathological features, we suggest that MLNS and IPN constitute a pathologic entity and that to separate them on a clinical or histological basis is nonsensical. The risk of coronary aneurysm and possible sudden death must be considered in patients with uncharacteristic symptoms including prolonged fever, conjunctivitis, exanthema, lesions in the oral mucosa, elevated sedimintation rate, and leukocytosis.
