A case of severe erythema nodosum induced by methimazole.

Erythema nodosum (EN), is the most common variant of septal panniculitis and is possibly a delayed hypersensitivity reaction triggered by a wide range of antigenic stimuli. Hypersensitivity reactions due to medications have been recognized as a cause of 3-10% of EN cases. Case reports of EN associated with the anti-thyroid drugs are quite rarely reported in the literature even if there is a common use of anti-thyroid drugs.

Methylene blue as an antioxidant agent in experimentally-induced injury in rat liver.

Background: We aimed to test the methylene blue (MB) as a dye and also to test its antioxidant activities in devascularization-induced liver injury.

Methods: Twenty rats weighing 240-280 g were randomly divided into two groups, each containing 10 rats. High-grade liver injury was induced by using a pair of long pliers with blades.

MRI findings of intramedullary spinal cryptococcoma.

Cryptococcus neoformans is a yeast that most commonly infects the central nervous system. Meningitis and meningoencephalitis are the most common presentations of cryptococcosis. Cryptococcoma, however, is a rare entity characterized by localized, solid, tumor-like masses that are usually found in the cerebral hemispheres or cerebellum, but are extremely rare in the spinal cord.
