BACKGROUND Dexmedetomidine hydrochloride, a highly selective 2-adrenoceptoragonist, is used in combination with local anesthetics for sedation and analgesia. It is known to be efficacious in adult patients and is enthusiastically expected to be successful for sedation in neonates. PATIENT The present case report details a term infant who was sedated by(More)
BACKGROUND Surgical intestinal disorders, such as necrotizing enterocolitis (NEC), focal intestinal perforation (FIP), and meconium-related ileus (MRI), are serious morbidities in very low-birthweight infants (VLBWI). The aim of this study was to compare the composite outcomes of death or neurodevelopmental impairment (NDI) in VLBWI with surgical intestinal(More)
OBJECTIVE Preterm infants are at greater risk of symptomatic cytomegalovirus (CMV) infection than term infants. Breast milk is the main source of perinatal CMV infections. This study evaluated the kinetics of CMV load in breast milk and the rate of postnatal CMV transmission via breast milk from mothers to their preterm infants. METHODS This was a(More)
We reported a patient with neonatal herpes simplex encephalitis in whom diffusion-weighted imaging was performed repeatedly. Diffusion-weighted imaging at 20h after the onset of seizures revealed scattered small spotty high intensity lesions in both hemispheres and a high intensity area in the left fronto-temporal lobe. There was no abnormal finding on(More)
We report a patient with a neonatal seizure in whom diffusion-weighted imaging (DWI) at 8 days of age revealed high-intensity areas in the genu and splenium of the corpus callosum. The patient was a 2-day-old girl born at 39 weeks of gestational age. No apparent signs of asphyxia were found at birth. Clinically, she had a clonic seizure of the left(More)
OBJECTIVE To clarify the prognostic value of conventional EEG for the identification of preterm infants at risk for subsequent adverse neurodevelopment in the current perinatal care and medicine setting. METHODS We studied 780 EEG records of 333 preterm infants born <34 weeks' gestation between 2002 and 2008. Serial EEG recordings were conducted during 3(More)
Many children with trisomy 18 have apneas from the neonatal period. It has been reported that some children with trisomy 18 have epilepsy, including epileptic apneas. However, no previous report has described epileptic apneas in trisomy 18 neonates. We retrospectively reviewed the clinical records of neonates with trisomy 18 who were born at Anjo Kosei(More)
Using a standard digital EEG system, we conducted simulations to determine the optimal locations and numbers of electrodes for seizure detection in neonates with reduced-channel EEG monitoring. The results showed that C3-C4 should be selected for a one-channel recording, but two-channel seizure monitoring is recommended for increased accuracy.
