Retrenchment is a problem confronting many public, private, and voluntary healthcare organizations. With budgetary restrictions in the public sector and the shift toward prospective payment systems and diagnosis-related reimbursement by third-party payors, healthcare executives must address several dilemmas and choices. Yet, retrenchment should not necessarily be viewed as a problem ...

A 20-year-old woman using an oral diet aid preparation containing phenylpropanolamine presented with an intracerebral hemorrhage and angiographic evidence of cerebral vasculitis. Gas chromatography demonstrated phenylpropanolamine in the urine. Even when used within recommended guidelines, phenylpropanolamine usage should be included in the differential diagnosis of patients presenting with intracranial hemorrhage.
