Optic neuritis caused by varicella infection in an immunocompetent child.

Chickenpox may lead to several neurologic complications, but optic neuritis has rarely been described. We report on a 6-year-old immunocompetent patient who presented with unilateral optic neuritis and severe visual loss because of varicella infection. A week after varicella eruption, the child experienced blurred vision.

Superior sagittal sinus thrombosis in steroid-resistant nephrotic syndrome.

An 8(1/2)-year-old-female child with steroid-resistant nephrotic syndrome developed sagittal sinus thrombosis while on pulse therapy with corticosteroids, presenting with recurrent vomiting, headache, and impaired consciousness. The diagnosis was established by cranial computed tomography, magnetic resonance imaging, and magnetic resonance angiography. She gradually recovered without neurologic sequelae while being treated with low-molecular-weight heparin (2 mg/kg/day).
