Perinatal immunization education improves immunization rates and knowledge: a randomized controlled trial.

Objectives: To determine if providing perinatal immunization education positively changes the immunization status of infants, influences the infant immunization knowledge, attitudes and beliefs of mothers and affects the intent to vaccinate children in Japan where immunization education is limited.

Methods: Pregnant women were recruited from three sites in Tokyo, Japan and were assigned to two intervention (pre- or postnatal education) groups and a control group. The immunization status of infants was assessed and a written survey was performed before and after the intervention.

Coronary artery lesions of incomplete Kawasaki disease: a nationwide survey in Japan.

Unlabelled: Incomplete Kawasaki disease (KD) is associated with delayed diagnosis and treatment, which in turn can lead to the development of coronary artery lesions (CALs). The aim of this study was to determine the epidemiological features of incomplete KD compared with complete KD and to identify risk factors for CALs from incomplete KD patients using data from a nationwide survey of 2007-2008 in Japan. A total of 23,263 patients were classified according to the number of principal clinical signs: 80% (n = 18,620) had complete forms of KD, 14.

Risk stratification in the decision to include prednisolone with intravenous immunoglobulin in primary therapy of Kawasaki disease.

Background: We reported previously that intravenous immunoglobulin (IVIG) plus prednisolone for initial therapy for Kawasaki disease (KD) prevented coronary artery abnormalities (CAA) more effectively than IVIG alone. However, questions remain as to whether PSL has potential benefit in all KD patients. The present study was designed to explore the possibility of stratified initial therapy including PSL in patients with and without a high predicted risk of being an IVIG nonresponder.

[Diagnosis of incomplete Kawasaki disease].

We defined incomplete Kawasaki disease (KD) as those having less than 5 principal symptoms of KD in this article. Japanese Nationwide KD surveys revealed that the prevalence of coronary artery lesion in incomplete KD is almost the same as that of complete KD. Thus, incomplete KD should not be equated with mild KD.

Prevalence of coronary artery abnormality in incomplete Kawasaki disease.

Background: The aim of the present study was to determine the prevalence of coronary artery abnormality (CAA) and other clinical features in patients with incomplete Kawasaki disease (iKD) using the data from the 17th Japanese nationwide survey of KD.

Methods: iKD was defined as the presence of four or fewer of the principal symptoms of the Japanese diagnostic guidelines, regardless of whether the patient had CAA. A total of 15,857 cases were analyzed.

Utility of coronary MR angiography in children with Kawasaki disease.

Objective: Although coronary arterial lesions due to Kawasaki disease (KD) should be evaluated as early as possible after the acute phase, conventional X-ray coronary angiography poses high risks for young children with the disease. The use of noninvasive MR coronary angiography is desirable, although it is difficult to produce clear images in young children. We developed a method to improve the quality of MR coronary angiography in young children.

Magnetic resonance coronary angiography to evaluate coronary arterial lesions in patients with Kawasaki disease.

We evaluated the efficiency of non-invasive magnetic resonance coronary angiography in detecting coronary arterial lesions in 106 patients, aged from 4 months to 37 years, with a median of 13 years, with Kawasaki disease. Non-contrast enhanced, free-breathing magnetic resonance coronary angiographic studies using both the steady-state free precession technique, namely bright blood imaging, and navigator-echo proton density weighted black blood imaging, so-called black blood imaging, were performed in all the patients. Conventional X-ray coronary angiography was performed in 70 patients with coronary arterial lesions.

Revision of diagnostic guidelines for Kawasaki disease (the 5th revised edition).

Diagnostic guidelines for Kawasaki Disease was revised to meet the present situation in 2002. This issue intends to explain new guidelines and their backgrounds. Major alterations are interpretation of cases with 4 or fewer febrile days shortened by early intravenous immunoglobulin treatment, and the clinical importance of atypical (incomplete, or suspected) cases.

Possible synergic effect of angiotensin-I converting enzyme gene insertion/deletion polymorphism and angiotensin-II type-1 receptor 1166A/C gene polymorphism on ischemic heart disease in patients with Kawasaki disease.

ACE I/D and AT1R 1166A/C polymorphisms are considered to comprise individual risk factors for the development of coronary disease. We sought to demonstrate that the ACE I/D and AT1R 1166A/C polymorphisms affect coronary artery stenosis in patients with Kawasaki disease (KD). We examined 147 healthy controls and 281 Japanese children with KD.

Use of laboratory data to identify risk factors of giant coronary aneurysms due to Kawasaki disease.

Background: Although some laboratory findings are known to be indicators of the risk of giant coronary aneurysm formation among Kawasaki disease patients, an appropriate cut-off point to predict aneurysm formation is not clear.

Methods: One hundred and five patients with giant coronary aneurysms were selected from the 15th and 16th nationwide surveys of Kawasaki disease in Japan. A total of 2936 patients without Kawasaki disease were recruited from a single hospital as a control group.

Multinational study of major breast milk carotenoids of healthy mothers.

Background: Carotenoids in serum vary between countries and within populations with evidence suggesting a qualitative relationship to diet. Breast milk carotenoids furnish a source of vitamin A and potentially provide immunoprotection and other health benefits for infants. There have been numerous studies of milk carotenoid concentrations in undernourished populations; however, carotenoid concentrations have not previously been compared in populations of well-nourished mothers.
