AIM Near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) allow non-invasive assessment of cerebral haemodynamics. We assessed cerebrovascular reactivity in preterm infants by investigating the relationship between NIRS- and TCD-derived indices and correlating them with severity of clinical illness. METHODS We recorded the NIRS-derived cerebral(More)
A case-control study of 47 laryngeal cancers in males of three counties of Washington State was conducted. Personal interview was used to obtain information on smoking, alcohol use, exposure to asbestos, and other substances, and x-rays of the head and neck area. Smoking and alcohol consumption were found to increase risk of laryngeal cancer independently,(More)
Children and adolescents with pulmonary hemorrhage are infrequently encountered in the emergency department (ED). We describe a case of a 16 year-old boy who presented to a pediatric ED with pulmonary hemorrhage and respiratory distress. The patient's unusual initial presentation resulted in the consideration of a broad differential diagnosis for his(More)
Background: The characteristics of cerebral autoregulation and the ideal range of systemic blood pressure in preterm infants remain unclear. Transcranial Ccerebral Doppler (TCD)1 and near infra-red spectroscopy (NIRS)2 are established techniques for the assessment of cerebral blood flow velocity (Fv) and cerebral oxygenation respectively.Aim: To study the(More)
