The utility of magnetic resonance imaging in the diagnostic evaluation of idiopathic olfactory loss.

Objectives/hypothesis: To report the utilization and cost effectiveness of magnetic resonance imaging (MRI) in the evaluation of patients with idiopathic olfactory loss.

Study Design: Case series with chart review.

Methods: A retrospective review of patients presenting with olfactory disorders at a university-based taste and smell center from July 1998 through October 2011 was performed to determine the diagnostic utility of MRI in the evaluation of patients with idiopathic olfactory loss.

Association of age at menarche with adult leg length and trunk height: Speculations in relation to breast cancer risk.

Background: It seems paradoxical that both increased height and earlier age at menarche (which predicts for shorter stature) are both associated with increased breast cancer risk.

Methods: Retrospective data from a parental cohort coupled with prospective interviews with and anthropometric measurements from their daughters were used. Multivariable linear regression analyses were conducted using mixed regression models to account for same-family participants.
