Neoplastic embolization to systemic and pulmonary arteries.

Objective: Arterial neoplastic emboli are uncommon, accounting for <1% of thromboemboli in the current literature. Nonetheless, this event may be associated with significant morbidity and mortality. Herein, we report a series of 11 cases of arterial neoplastic emboli from a single tertiary care center along with a comprehensive review of the literature to date.

Three-dimensional volumetric computed tomographic scoring as an objective outcome measure for chronic rhinosinusitis: clinical correlations and comparison to Lund-Mackay scoring.

Background: We aimed to test the hypothesis that three-dimensional (3D) volume-based scoring of computed tomography (CT) images of the paranasal sinuses was superior to Lund-Mackay CT scoring of disease severity in chronic rhinosinusitis (CRS). We determined correlation between changes in CT scores (using each scoring system) with changes in other measures of disease severity (symptoms, endoscopic scoring, and quality of life) in patients with CRS treated with triamcinolone.

Methods: The study group comprised 48 adult subjects with CRS.

Formal procedural skills training using a fresh frozen cadaver model: a pilot study.

Graduating medical students are expected to be proficient in a number of procedural skills. A structured curriculum is infrequently available. In addition, the use of a mannequin tends to be unrealistic and students continue to have some anxiety when performing procedures on patients.

Heart and liver disease in 32 patients undergoing biopsy of both organs, with implications for heart or liver transplantation.

Objective: To determine underlying conditions in patients undergoing both heart and liver biopsies.

Patients And Methods: Our study group consisted of 32 patients at the Mayo Clinic in Rochester, Minn, who underwent both endomyocardial and nonsurgical liver biopsies and who underwent at least one of these procedures between January 1,1981, and December 31,2000. Patients were categorized as having (1) heart disease affecting the liver, (2) liver disease affecting the heart, (3) the same disease affecting both organs, or (4) different diseases affecting each organ independently.

Outcomes of the gross and developmental anatomy teaching assistant experience.

During the first-year Gross and Developmental Anatomy Course at Mayo Medical School, third-year medical students volunteer as teaching assistants (TAs). Their responsibilities include preparing for dissection, instructing students during dissection, writing examination questions, and giving a lecture. To evaluate the academic and professional impact of this experience on former TAs, a survey instrument was developed, and was sent to former TAs from the past 17 years.
