Limited data are available related to the effects of cardiovascular risk factors on abdominal arterial stiffness using carotid and brachial artery indices. Therefore, we aimed to determine arterial changes in obese children and investigate any relation with cardiovascular risk factors. ⋯ Abdominal arterial stiffness parameters as well as carotid intima-media thickness and brachial arterial flow-mediated dilatation assessment were similarly useful in identifying obese children with cardiovascular risk factors. Insulin resistance is related with the augmented rigidity of the aortic wall in obese children.

Comparative Study
Use of non-invasive total hemoglobin measurement as a screening tool for anemia in children.
Universal screening for anemia is important in children, but invasive blood sampling is required. A new device (Radical-7® Pulse CO-Oximeter™, Masimo, Irvine, CA, USA) now enables non-invasive hemoglobin concentration (SpHb) measurement to be done, but the usefulness of this device for anemia screening in children is unclear. The objective of this study was to compare SpHb with complete blood count (CBC) using a hematology analyzer (Microsemi® LC-667CRP; Fukuda Denshi, Tokyo, Japan). ⋯ The correlation of Radical-7® and Microsemi® was 0.602 (P < 0.0001). On Bland-Altman comparison, bias was -0.6 ± 1.1 g/dL. Even though further improvement is required, Radical-7® offers many possibilities in the context of primary screening.

Several drugs, when used chronically in very preterm infants, are considered to be associated with the development of late-onset circulatory collapse (LCC), which can lead to neurodevelopmental impairment. Despite its clinical importance, conclusive risk factors for LCC have yet to be identified. The aim of the present study was to investigate the relationship between LCC and diuretics, methylxanthines, levothyroxine, and sodium chloride. ⋯ Methylxanthine use was significantly associated with LCC onset. Diuretics may have the ability to provoke LCC through sodium wasting, resulting in a negative balance of the electrolyte. The incidence of LCC could be lowered by paying particular attention to infants' sodium balance, and by aggressive methylxanthine treatment.

Four patients with a thrombus in a coronary artery aneurysm due to Kawasaki disease (KD) were treated at our hospital between 1994 and 2009. All the cases were treated with intravenous coronary thrombolysis (IVCT) therapy and the cases with acute myocardial infarction were treated with additional intracoronary thrombolysis therapy. Although both thrombolytic therapies were effective, IVCT required more time than intracoronary thrombolysis to resolve the thrombus. We concluded that IVCT can be used as the first-line thrombolytic therapy for KD, except in cases with acute myocardial infarction.

Reported herein is a coronary anomaly that occurred in a young adolescent athlete who presented with cardiopulmonary arrest. The patient was resuscitated and treated with therapeutic hypothermia. ⋯ Enhanced computed tomography of the heart indicated an anomalous left main coronary artery originating from the right coronary sinus and coursing between the aorta and the pulmonary artery. The patient underwent surgical intervention with coronary artery bypass grafting to prevent symptom recurrence.
