BACKGROUND Peri-lesional edema is a serious and well-known complication of stereotactic radiosurgery (SRS). Here we evaluated edema risk after SRS and assessed its formation and resolution dynamics. PATIENTS AND METHODS 107 patients underwent SRS for heterogeneous diagnoses: 34 (29%) with arteriovenous malformations, 38 (35%) with meningiomas, 16 (15%) with metastatic tumors, 16 (15%) with ac...

BACKGROUND We assessed optimal intravascular ultrasound (IVUS) criteria for predicting functional significance of intermediate coronary lesions. METHODS AND RESULTS Overall, 201 patients with 236 coronary lesions underwent IVUS and invasive physiological assessment before intervention. Fractional flow reserve (FFR) was measured at maximal hyperemia induced by intravenous adenosine infusion. F...

PURPOSE To evaluate topical interferon alpha-2b (IFNalpha2b) as a lone therapy in the treatment of primary conjunctival and corneal intraepithelial neoplasia (CIN). METHODS Noncomparative, prospective, interventional case series. Seven patients from three institutions, treated between February and October 1999, with presumed primary CIN lesions (clinically diagnosed by corneal specialists) we...

Cryogenic lesions were produced in the brains of rhesus monkeys and the accompanying edema measured by quantitative chemical methods. No effect on this type of edema could be demonstrated in animals treated with massive doses of steroids.

PURPOSE Cicatricial pemphigoid is a rare chronic autoimmune disease, characterized by progressive alterations on the skin and mucous membranes. Ocular lesions consists of chronic conjunctivitis, progressive subepithelial fibrosis on the conjunctival fornix together with symblepharon formation, obstruction of the Meibomian ducts, sicca syndrome, and occasionally, entropion associated with conseq...

Indirubin is a Chinese medicine extracted from indigo and known to be effective for treating chronic myelogenous leukemia, neoplasia, and inflammatory disease. This study evaluated the in vivo anti-inflammatory activity of indirubin in a lipopolysaccharide- (LPS-) induced mouse mastitis model. The indirubin mechanism and targets were evaluated in vitro in mouse mammary epithelial cells. In the ...

An experimental model for acute allergic optic neuritis was produced in adult strain 13 guinea pigs by sensitization with isogenic spinal cord emulsion in complete Freund's adjuvant. These animals exhibited two distinct clinical patterns: (1) "retrobulbar optic neuritis," with a diminished pupillary response to light despite a normal fundus, and (2) "neuroretinitis," with a diminished pupillary...

Purified collagenase which attacks only native collagen and gelatin was injected intravenously into the normal and DCA hypertensive rats to determine whether damage in collagenous tissue of the vascular wall would result in diffuse necrotizing lesions of the vessels. In the normal rats subclinical edema, proteinuria, and mild degenerative lesions in the small arteries and arterioles were produc...

Hypertensive encephalopathy rarely presented with widespread edema in the cerebral white matters, deep structures and whole brainstem. A 80-year-old woman manifested as high arterial blood pressure, visual disturbance, severe headache, nausea, and vomiting. T2-weighted and fluid-attenuated inversion recovery magnetic resonance imaging showed high signal-intensity lesions in the cerebral white m...
