Idiopathic intrauterine constriction/closure of the ductus arteriosus, which is distinct from that secondary to maternal exposure to non-steroidal anti-inflammatory drugs, such as indomethacin, or structural cardiac defect, is an uncommon event that often results in severe fetal-neonatal morbidity and mortality. We reported a case of idiopathic fetal ductal(More)
In this case-control study, we examined infants delivered vaginally at 37 weeks or later to identify factors associated with transient tachypnea of the newborn (TTN). We reviewed the obstetric records of all vaginal deliveries at the Japanese Red Cross Katsushika Maternity Hospital from 2005 through 2007. Demographic information and the characteristics of(More)
Full-term cord blood (TCB) hematopoietic stem/progenitor cells (HSC/HPCs) are used for stem cell transplantation and are well characterized. However, the properties of preterm cord blood (PCB) HSC/HPCs remain unclear. In the present study, we compared HSC/HPCs from TCB and PCB with respect to their expression of surface markers, homing capacity and ability(More)
We describe an infant with nemaline myopathy accompanied by hypertrophic cardiomyopathy. The patient required long-term, intermittent positive-pressure ventilation after birth owing to muscle weakness, and cardiac failure developed during infancy. We diagnosed hypertrophic cardiomyopathy with outflow tract obstruction, and treated the heart failure with(More)
We describe an uncircumcised male infant treated for urinary tract infection who exhibited multiple hormonal and electrolyte abnormalities consistent with a diagnosis of transient pseudohypoaldosteronism. Successful treatment of the urinary tract infection was accompanied by the resolution of all hormonal and electrolyte abnormalities, including(More)
Congenitally corrected transposition of the great arteries (ccTGA) is a rare cardiac defect characterized by the atria connecting with anatomically discordant ventricles and the ventricles connecting with discordant and transposed great arteries, which allows hemodynamic compensation. Most patients with ccTGA have associated intracardiac anomalies, which(More)
Group B Streptococcus (GBS) is an important pathogen that causes neonatal sepsis and meningitis, which have high mortality and morbidity. Most cases of infection are early onset, with late onset infections being less common. Moreover, many cases of infection are caused by type III GBS, while type Ib GBS infections are rare. We report a case of late-onset(More)
Over a five-year period, we reviewed 19 fetuses who were prenatally diagnosed with congenital heart disease, including hemodynamically significant arrhythmias. Five of them had fetal tachyarrhythmias, and 14 had structural heart disease. The outcomes were: six intrauterine deaths, five neonatal deaths, and three infant surgeries. Six of the fetuses had(More)
Intussusception occurring in premature infants is exceedingly rare and shows substantially different characteristics from that in the typical age group or non-premature neonates. We present a case of intussusception in an extremely premature infant following bacterial sepsis, in which necrotizing enterocolitis was initially suspected. The correct diagnosis(More)
