Obesity and pulmonary embolism: the mounting evidence of risk and the mortality paradox.

Purpose: To determine the prevalence of pulmonary embolism in obese patients according to age, gender and comorbid conditions and explore the relation of obesity to mortality.

Methods: The number of patients discharged from short-stay hospitals throughout the United States from 1998-2008 with pulmonary embolism who were obese or not obese, and in-hospital all-cause mortality were determined from the Nationwide Inpatient Sample.

Results: From 1998-2008, 203,500 of 17,979,200 (1.

Obesity and thromboembolic disease.

Various abnormalities of hemostasis have been described in obesity, mainly concerning increased levels of plasminogen activator inhibitor-1, but other abnormalities of coagulation and platelet activation have been reported as well. Circulating microparticles have also been observed in obese patients. These suggest that obesity would be a risk factor for venous thromboembolism (VTE).

Diabetes mellitus and risk of venous thromboembolism.

Background: : To determine if diabetes mellitus is a risk factor for venous thromboembolism (VTE).

Research Design And Methods: : Data from the National Hospital Discharge Survey were analyzed from 1979 to 2005. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify diseases.

Olfactory groove meningiomas from neurosurgical and ear, nose, and throat perspectives: approaches, techniques, and outcomes.

Objective: To review the surgical approaches, techniques, outcomes, and recurrence rates in a series of 80 olfactory groove meningioma (OGM) patients operated on between 1990 and 2003.

Methods: Eighty patients underwent 81 OGM surgeries. Tumor diameter varied from 2 to 9 cm (average, 4.
