Stiff-person syndrome following tick-borne meningoencephalitis.

Stiff-person syndrome (SPS) is a rare disorder characterized by muscle stiffness and painful spasms. Misdiagnosis may occur due to the fact that the clinical picture of SPS is often atypical. The main pathophysiologic mechanism underlying the development of SPS is insufficient inhibition at the cortical and spinal levels.

Exposure to iodomethane and dichloromethane associated with a confusional state.

Dichloromethane and iodomethane are colorless relatively volatile liquids, which are used as solvents in chemical manufacturing processes. The major route of exposure is via inhalation and to a lesser extent through the skin and digestive tract. Both substances are characterized by significant neurotoxic effects.

Cerebral venous thrombosis after a cesarean delivery.

Cerebral venous thrombosis (CVT) is a serious condition affecting mostly women. This report concerns two cases of women who developed CVT within 14 days of cesarean delivery. Magnetic resonance angiography of the brain (venous phase) is the best modality to diagnose the condition, and parenteral application of low-molecular-weight heparin is the most beneficial treatment.

Dynamic and delayed contrast enhancement in upper abdominal MRI studies: comparison of gadoxetic acid and gadobutrol.

Objective: To prospectively compare contrast properties of extracelullar (gadobutrol) and hepatospecific (gadoxetic acid) contrast agents in upper abdominal MRI studies.

Materials And Methods: Standardized (0.1 ml/kg) dose of gadobutrol (56 subjects) and gadoxetic acid (51 subjects) was administered intravenously by MRI-compatible injector at 2 ml/s, followed by 20 ml saline flush.
