A linear-array real-time ultrasound scanner with a 5 MHz probe was used to examine the brains of 31 infants born at less than 33 weeks of gestation. The equipment was mounted on a small trolley and the infants could easily be scanned in their incubators. 7 of the 31 infants were shown to have cerebral lesions, including haemorrhages into the germinal layer… (More)
Real-time ultrasound was used to examine the brains of all 95 infants born at less than 33 weeks of gestation who were admitted to the neonatal unit of University College Hospital in 1979. Evidence was obtained which strongly suggested that pneumothorax causes and aggravates haemorrhage into the germinal layer and ventricles of preterm infants.
A linear-array real-time ultrasound scanner was used to examine the brains of all 95 infants born at less than 33 weeks of gestation who were admitted to the neonatal unit of University College Hospital in 1979. Abnormalities were detected in 41 (43%). 36 infants had haemorrhages into the germinal layer (GLH) and/or ventricles (IVH). 8 infants had cerebral… (More)
The brains of 95 consecutively admitted infants born at less than 33 weeks gestation were scanned with ultrasound. Thirty-six (38%) had periventricular haemorrhage (PVH). Eight (8%) had cerebral atrophy (together with PVH in 5). Twelve (40%) of the 30 infants in whom satisfactory timing of PVH was possible bled on the first day of life, but the median age… (More)
for their comments and questions. We owe a special debt to Junko Itô and Armin Mester, who reviewed a draft of the NELS handout and provided much useful feedback.
Cultured cells established from the bone marrow of a child with null-cell acute lymphoblastic leukaemia (ALL) have been studied. After 8 months in vitro, the cytological, cytochemical and immunological properties of the cultured cells were very similar to those of the patient's cells. Many of the cultured cells had morphological and cytogenetic… (More)
