Most morphometric studies of the human trachea have relied on plain radiographs with their attendant limitations. Reports using computed tomography (CT) have focused on the growing trachea or one particular dimension. The aim of this study was to document the morphometry of the adult trachea in vivo using high-resolution chest CT scans, supplemented by data(More)
PURPOSE To evaluate prospectively the sensitivity of ultrasonography (US) in the diagnosis of biliary atresia (BA), with surgery as the reference standard. MATERIALS AND METHODS After institutional ethical approval and with informed parental consent, 90 consecutive fasting infants with conjugated hyperbilirubinemia underwent detailed US studies performed(More)
BACKGROUND Foreign body inhalation is a common and life-threatening emergency, and is most prevalent in young children. The traditional view is that tracheobronchial anatomy determines that an inhaled foreign body is more likely to enter the right main bronchus. This view has been challenged in young children, in whom the distribution of inhaled objects is(More)
OBJECTIVE The chorda tympani is at risk of iatrogenic injury throughout its course. This paper reviews the clinical anatomy of the nerve in adults. DESIGN Systematic literature review. METHOD Relevant English-language articles were identified using five electronic databases and one search engine. Data from approximately 70 scientific papers were(More)
BACKGROUND AND AIMS Interstitial cells of Cajal (ICC) are distributed with smooth muscle throughout the gastrointestinal tract and are involved in regulating motility. ICC were recently discovered in the wall of the human gallbladder. This study sought to determine whether ICC are present in human bile ducts. METHODS Biliary tract samples were obtained(More)
Despite its clinical importance, the surface anatomy of the pterion is inconsistently reported. This study reappraises the surface marking of the pterion and its relationship to the middle meningeal artery (MMA). The position and morphology of the pterion were analyzed in the Frankfurt plane in 76 adult skulls and 50 adult cranial cone beam CT scans.(More)
The importance of values in design work is gaining increasing attention. However, some of the work to date takes an approach which starts with generic values, or assumes values are constant. Through discussion of three accounts of value discovery and value evolution in projects focused on exploring novel uses of ubiquitous computing, we complement current(More)
Tailoring graft size to small paediatric recipients is a challenge. We have developed a reduced left lateral segment as an alternative to monosegment transplantation for small size recipients. Since November 2000, 89 children have been transplanted with 100 deceased donor liver grafts in our unit. Our median patient and graft survival is 89% and 88%(More)
PURPOSE Identification of the second dorsal sacral foramen (S2F) by sonographic imaging is a possible first step in localising the branches of the dorsal sacral rami. The aim of this investigation is to develop an imaging approach to assist the rapid identification of S2F using a well-known regional landmark, the posterior superior iliac spine (PSIS). (More)
