H Fayad, M Gilles, T Pan, D Visvikis
PURPOSE: Respiratory motion reduces the sensitivity and specificity of medical images especially in the thoracic and abdominal areas. It may affect applications such as cancer diagnostic imaging and/or radiation therapy (RT). Solutions to this issue include modelling of the respiratory motion in order to optimize both diagnostic and therapeutic protocols. Personalised motion modeling required patient specific four dimensional (4D) imaging which in the case of 4D computed tomography (4D CT) acquisition is associated with an increased dose...

Bone abnormalities of orbit seen in patients with trauma or radiolesion are accompanied by enophthalmos or exophthalmos. Conventional measurements of eyeball protrusion with Hertel's exophthalmometer or with computed tomography do not provide accurate and reliable data, especially in patients with asymmetry of lateral orbital rims. PURPOSE: To develop a method of computed exophthalmometry that provides accurate and reliable measurements in patients with various orbital conditions. MATERIAL AND METHODS: Medical records and computerized axial tomography scans of 25 patients' orbits without false enophthalmos or exophthalmos were analyzed posthoc...

C Y Lee, C Beanland, D Goeman, N Petrie, B Petrie, F Vise, J Gray, R A Elliott
WHAT IS KNOWN AND OBJECTIVE: Polypharmacy, medication errors and adverse events are common in older people receiving home nursing medication management support. Access to clinical pharmacists is limited. In Australia, few home nursing clients receive a general practitioner (GP)-initiated pharmacist-led Home Medicines Review, despite their eligibility and community nurses' (CN) efforts to facilitate this. An integrated home nursing clinical pharmacy service, in which CNs directly referred clients to a pharmacist, was therefore developed and piloted...

Vaccine safety studies are often electronic health record (EHR)-based observational studies. These studies often face significant methodological challenges, including confounding and misclassification of adverse event. Vaccine safety researchers use self-controlled case series (SCCS) study design to handle confounding effect and employ medical chart review to ascertain cases that are identified using EHR data. However, for common adverse events, limited resources often make it impossible to adjudicate all adverse events observed in electronic data...

BACKGROUND/OBJECTIVES: Infantile hemangiomas are the most common benign tumors of childhood. Although some children with periocular infantile hemangiomas do not require treatment, these lesions may result in amblyopia and visual impairment if not properly treated. We have attempted to characterize clinical features of periocular infantile hemangiomas that predict negative ocular outcomes and thus require prompt referral to an ophthalmologist and initiation of therapy. METHODS: This study included children with periocular infantile hemangiomas consecutively seen at Ann & Robert H...
