Life-threatening hypoglycemia resulting from a nonislet cell tumor.

Nonislet cell tumor-induced hypoglycemia (NICTH), also known as Doege-Potter syndrome, is a rare paraneoplastic syndrome seen in association with various nonpancreatic tumors, benign and malignant, and comprising mesenchymal, vascular, or epithelial cell types. We report a case of recurrent life-threatening hypoglycemia from a large pelvic solitary fibrous tumor.

Angiotensin II receptor blocker valsartan suppresses reactive oxygen species generation in leukocytes, nuclear factor-kappa B, in mononuclear cells of normal subjects: evidence of an antiinflammatory action.

In view of the pro-oxidant and proinflammatory effects of angiotensin II, we have tested the hypothesis that valsartan, an angiotensin receptor blocker, may exert a suppressive action on reactive oxygen species (ROS) generation, nuclear factor kappa B (NF-kappa B) in mononuclear cells. Four groups of eight normal subjects were given 1) 160 mg daily of valsartan, 2) 80 mg daily of simvastatin, 3) 40 mg quinapril, or 4) no treatment. Fasting blood samples were obtained before treatment and at d 1, 8, and 14 (7 d after the cessation of the drug).
