The aim of the study was to determine factors that affect adverse long-term pulmonary outcome in premature infants. ⋯ Among selected perinatal variables, prenatal risk factors, particularly SGA, contributed to prolonged dependency on oxygen and/or positive-pressure ventilatory support, in combination with neonatal risk factors.

Late-onset circulatory collapse (LCC) is a disorder in which blood pressure decreases and oliguria suddenly occurs in preterm infants who have survived the acute stage, leading to shock, without contributing underlying factors. In order to evaluate hemodynamic changes during LCC, the correlation between myocardial functions and organ blood flow was investigated with echography. ⋯ LCC is a distributive shock, characterized by a hyperdynamic state and decreased afterload. Echographic examination of organ flow during LCC is useful in understanding the pathophysiology of the disorder.

Efficacy of recombinant human soluble thrombomodulin for childhood hemolytic uremic syndrome.
Recombinant human soluble thrombomodulin (rhTM) is a promising therapeutic natural anticoagulant and is used clinically for the treatment of disseminated intravascular coagulation (DIC). Herein is reported the cases of two HUS children treated with rhTM. The patients were diagnosed as having typical HUS on the basis of thrombocytopenia, hemolytic anemia, acute renal failure, and the detection Escherichia coli 0157. ⋯ Urinary protein excretion gradually diminished and a decrease in serum creatinine level was observed. The patients did not require dialysis therapy. The present results suggest that rhTM may be a safe and effective treatment for DIC complicated with HUS in children.

Although oxidative stress-related diseases mostly affect neonates with extremely low birthweight, healthy preterm and term newborns may also be at risk of oxidative damage. There have been studies concerning factors that affect the level of oxidative stress biomarkers in term and preterm neonates, but there has not been a study of the reference values of oxidative stress biomarkers in healthy newborns having no risk factors. The aim of the present study was to clarify this issue. ⋯ This study can be used as a guide for the reference range of TAC and TOS values for healthy term newborns.

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.
