OBJECTIVES Because intraventricular hemorrhage (IVH) often precedes the development of sonographically defined white matter damage (WMD) in very preterm infants, we sought to identify the IVH characteristics that predict WMD. HYPOTHESES We evaluated variations on the null hypothesis that infants with IVH are no more likely than infants without IVH to have(More)
Echolucent images (EL) of cerebral white matter, seen on cranial ultrasonographic scans of very low birth weight newborns, predict motor and cognitive limitations. We tested the hypothesis that markers of maternal and feto-placental infection were associated with risks of both early (diagnosed at a median age of 7 d) and late (median age = 21 d) EL in a(More)
Over a 34-month period, 1105 newborns weighing between 501 and 2000 g at birth were enrolled in a prospective study of the aetiology and consequences of neonatal brain haemorrhage. The three participating hospitals care for approximately 85% of births in the study weight range in Middlesex, Monmouth and Ocean counties, New Jersey. Cranial ultrasonographic(More)
The objective of this study was to evaluate to what extent (1) the characteristics of localization, distribution, and size of echodense and echolucent abnormalities enable individuals to be designated as having either periventricular hemorrhagic infarction or periventricular leukomalacia and (2) the characteristics of periventricular hemorrhagic infarction(More)
Spontaneous perforation of the biliary tract in infancy is rare; fewer than 100 cases have been reported. The authors report on two patients with spontaneous biliary perforation (SBP) who were treated during the past 5 years. One of the patients, a 10-month-old boy, presented with an extensive retroperitoneal mass, without jaundice. He was found to have a(More)
BACKGROUND Methotrexate is an effective, safe, low-cost alternative to surgery for treating tubal pregnancies. To our knowledge, there have only been two other reported attempts at treating abdominal pregnancy with methotrexate. CASE Despite two courses of treatment with methotrexate, the pregnancy persisted, and laparoscopy permitted a tissue diagnosis(More)
Failure of a small premature newborn to adequately evacuate meconium for days or weeks has been attributed to "probable necrotizing enterocolitis (NEC)" or "microcolon of prematurity." The authors present an unusual type of "meconium plug syndrome" with the same clinical picture, seen in tiny premature babies (500 to 1,500 g), which required a contrast(More)
PURPOSE To explore the potential for the information superhighway to provide radiologists with new opportunities. MATERIALS AND METHODS The Internet was used as the communication and distribution medium. MOSAIC, a graphical interface, provided access for clients, and a computer was used to serve text, images, sound, and cine onto the Internet. RESULTS(More)
The uterine adenofibroma is a form of mixed mesodermal tumor in which both epithelial and stromal components are benign. A case is presented in which a patient with this lesion was treated with excision of the tumor rather than hysterectomy. Two years later, she developed a recurrence of the lesion, which was again treated with wide local excision. A(More)
The reliability of cranial ultrasound diagnosis in the premature neonate was examined using data from an ongoing multicentre study of the epidemiology and long-term consequences of neonatal brain haemorrhage. First week ultrasound films (obtained at 4 hours, 24 hours and 7 days) from 60 study subjects were randomly selected for independent review by two(More)
