Iliopsoas abscess associated with endovascular infection: an acute case of chronic Q fever.

fever is a zoonosis caused by Coxiella burnetii, which occurs worldwide. After acute Q fever infection, 1% to 5% of patients develop chronic Q fever. Chronic Q fever usually presents as endocarditis or endovascular infection.

Impaired KATP channel function in the fetoplacental circulation of patients with type 1 diabetes mellitus.

Objective: The increased perinatal morbidity in diabetes may be partly related to vascular dysfunction. Because potassium channels play an important role in the regulation of vascular tone, this study explores the impact of diabetes on potassium channel function in the fetoplacental vascular bed.

Study Design: Vascular potassium channel function was investigated by ex vivo dual perfusion of isolated placental cotyledons (n = 47).
