optic neuritis/potassium

Multiple sclerosis (MS) is a common inflammatory disease of the central nervous system that results in persistent impairment in young adults. During chronic progressive disease stages, there is a strong correlation between neurodegeneration and disability. Current therapies fail to prevent

Hyponatremia associated with low-dose trimethoprim in patients on concomitant systemic corticosteroid therapy has rarely been reported. Here, we describe a 57-year-old woman with a history of diabetes mellitus and hypertension treated with telmisartan, who presented with progressive visual

A case of Sweet's syndrome treated with potassium iodide is hereby described. The patient responded well a few days after the initiation of therapy, but the evolution was complicated with a severe clinical deterioration two weeks later. Systemic vasculitis was diagnosed on the basis of significant

OBJECTIVE To compare the efficacy of intravenous methylprednisolone and intravenous dexamethasone on visual recovery and evaluate their side-effects for the treatment of optic neuritis. METHODS Prospective, randomized case-controlled study including 21 patients of acute optic neuritis presenting

Chronic disability in multiple sclerosis is linked to neuroaxonal degeneration. 4-aminopyridine (4-AP) is used and licensed as a symptomatic treatment to ameliorate ambulatory disability in multiple sclerosis. The presumed mode of action is via blockade of axonal voltage gated potassium channels,

BACKGROUND Autoantibodies to glial, myelin and neuronal antigens have been reported in a range of central demyelination syndromes and autoimmune encephalopathies in children, but there has not been a systematic evaluation across the range of central nervous system (CNS) autoantibodies in

BACKGROUND Amiodarone (Cordarone; Wyeth, Ayerst, New York) is a potassium channel blocking antiarrythmal medication indicated for recurrent ventricular fibrillation and recurrent hemodynamically unstable ventricular tachycardia. Chemically, it is classified as an iodinated benzofuran derivate

BACKGROUND Patients with paraocular sinus masses may manifest ocular complications, including orbital displacement, proptosis, diplopia, restricted extraocular muscles, decreased vision, chemosis, pain, and optic neuritis. METHODS Two patients with paraocular sinus masses came to our clinic for

This case report deals with a 29 year-old female patient with a prior history of a vestibular syndrome and elapsing optic neuritis that presented paroxystic episodes of painful tonic contractions affecting the right hemibody, especially the upper limb. In the hand the clinical picture was similar to

A 28-year-old man ingested methylene dianilene in potassium carbonate and gamma-butyrolactone. He developed toxic optic neuritis, with severe visual dysfunction (not previously reported in humans), prolonged toxic hepatitis, with disturbed liver-function tests 18 months after the incident, and other

Nonarteritic ischemic optic neuropathy (NAION) is one of the most common acute unilaterally onset optic nerve diseases. One management problem in terms of NAION is the difficulty of differential diagnosis between NAION and anterior optic neuritis (ON). A second problem is that there is no

OBJECTIVE To describe the features of adult patients with benign, unilateral cerebral cortical encephalitis positive for the myelin oligodendrocyte glycoprotein (MOG) antibody. METHODS In this retrospective, cross-sectional study, after we encountered an index case of MOG antibody-positive
