Background & Aims: Low serum levels of vitamin D have been associated with Crohn's disease (CD). However, it is unclear whether low vitamin D levels cause CD or CD reduces serum vitamin D.
Methods: United States military personnel with CD (n = 240) and randomly selected individuals without CD (controls, n = 240) were matched by age, sex, race, military branch, and geography.
Acute hepatotoxicity secondary to infliximab can occur with or without autoimmunity. A growing body of infliximab drug-induced liver injury cases without autoantibody formation is emerging. Nearly all other reported cases occur after at least three doses.

Methods: Using International Classification of Diseases, Ninth Revision codes, patients with Crohn's disease (CD) and ulcerative colitis (UC) seen within the military health care system (Tricare) from October 1, 2008 to September 30, 2009 were identified. This database comprised all active duty military, retirees, and dependents.
Background And Objectives: Total antioxidant capacity (TAC) reflects the capacity of plasma, or other body fluid, to resist oxidation. The aim of the present study was to assess the prognostic value of Pholasin as a probe for the determination of plasma TAC.
Design And Methods: Plasma samples either oxidised using the free radical generator 2'-azobis-(2-amidinopropane) hydrochloride (AAPH) at 60 degrees C for 180 min or obtained from diabetic (type 1 and type 2) patients (n = 61 and 124, respectively) with or without polyneuropathy (PN) and/or cardiovascular autonomic neuropathy (CAN) and control subjects (n = 70) were analysed for TAC status.
