Accuracy of crescent sign on ocular ultrasound in diagnosing papilledema

AIm To study the usefulness of orbital ultrasonography in the diagnosis of *** Fifty patients who were referred to the neurophthalmology clinic and clinically suspected to have papilledema were selected. Thorough, clinical examination with slitlamp biomicroscopy and visual acuity assessment was done. These patients underwent ultrasonography to demonstrate the crescent sign. The patients were further evaluated with the neurologist and magnetic resonance imaging(mRI) thus confirming the diagnosis of papilledema. The results of our ultrasonographic evaluation were correlated with final diagnosis after thorough clinical evaluation, imaging and the neurologist's *** Out of 50 patients diagnosed having papilledema on mRI, 46(92%) showed crescent sign on B scan ultrasonography. Headache was most common presenting complaint in 47(94%) and idiopathic intracranial hypertension was most common underlying cause of papilledema in 30(60%) ***"Crescent sign" seen on ultrasonography is a sensitive tool for diagnosis of papilledema. It is cost effective, less cumbersome and effective tool to differentiatebetween papilledema and pseudo papilledema before subjecting the patients to costly investigations like mRI. A positive crescent sign should always be followed by mRI to find out the cause of papilledema.

Family Organization in the Care of Pediatric Heart Transplant Patients:The Genogram as an Investigative Tool

Health 2015年第11期7卷 1409-1418页

This study aimed to describe structure, functionality and development of pediatric heart transplant families, from the understanding of the experienced chronic condition. A descriptive, exploratory study using a qualitative approach was developed in a hospital situated in a city of Northeast Brazil, in 2012. The study was conducted with three families, using the Calgary Family Assessment model (CFAm). In addition to the genogram, an analysis of the children’s/adolescents’ family members was conducted at the time of interview. Two families were binuclear families and one was mononuclear. From the evaluation, it was possible to determine the care and support network of children and adolescents with heart transplants, as well as some difficulties faced by the investigated families. Nurses are important in this family context since the visualization of the family genogram can generate a change in the nursing care to each family.
