OBJECTIVE
To report an unusual presentation of pellucid marginal degeneration (PMD).
METHODS
A 57-year-old man with history of corneal ectasia experienced acute hydrops and spontaneous corneal perforation in his right eye. Examination revealed PMD in both eyes. After initial treatment with
Globoid cell leukodystrophy (GLD) is a disorder of the central and peripheral nervous systems caused by the deficiency of the lysosomal enzyme galactocerebrosidase (GALC). The pathological changes associated with the disease include accumulation of globoid cells and loss of myelin due to production
The Twitcher mouse (Twi/Twi) is a recently identified mutant experimental model for human globoid leukodystrophy. Affected mice develop neurologic abnormalities with demyelination of white matter and peripheral nerve due to an inherited enzyme deficiency. The neuropathy has unusual pathologic
OBJECTIVE
To report a case of secondary corneal amyloidosis in a chronic hydrops lesion of a patient with pellucid marginal degeneration (PMD).
METHODS
Clinicopathologic case report with a review of the literature. A 63-year-old man with PMD developed acute hydrops in 1999, which never resolved and
Canavan disease is a devastating autosomal recessive leukodystrophy leading to spongiform degeneration of the white matter. There is no cure or treatment for Canavan disease, and disease progression is poorly understood.
We report a new presentation of a patient found to have Canavan disease; brain
Megalencephalic leukoencephalopathy with subcortical cysts (MLCs) disease is a rare inherited, autosomal recessive form of childhood-onset spongiform leukodystrophy characterized by macrocephaly, deterioration of motor functions, epileptic seizures and mental decline. Brain edema, subcortical fluid
Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a type of leukodystrophy characterized by white matter edema, and it is caused mainly by recessive mutations in MLC1 and GLIALCAM genes. These variants are called MLC1 and MLC2A with both types of patients sharing the same clinical
OBJECTIVE
The purpose of this study was to explore the protective effect of AP on LPS-induced PMD and ALI.
METHODS
Male SD rats were continuously infused with LPS (5 mg/kg/h) for one hour to induce PMD and ALI. AP was administrated orally one hour before LPS exposure. Arterial blood pressure and HR
OBJECTIVE
The renal impairment in children with methylmalonic aciduria has seldom been reported. To improve knowledge in this aspect, clinical data of five cases with methylmalonic aciduria with renal involvement were analyzed and the results are reported in this paper, which may be of some help in
Canavan disease (CD) is a human early-onset leukodystrophy, genetic in nature and resulting from an autosomally inherited recessive trait. CD is characterized by loss of the axon's myelin sheath, while leaving the axons intact, and spongiform degeneration, especially in white matter. It is an
Mutations in the MLC1 gene, which encodes a protein expressed in brain astrocytes, are the leading cause of MLC, a rare leukodystrophy characterized by macrocephaly, brain edema, subcortical cysts, myelin and astrocyte vacuolation. Although recent studies indicate that MLC1 protein is implicated in
Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a rare type of leukodystrophy characterized by white matter edema. Autosomal-recessive mutations in MLC1 cause MLC type 1, and autosomal-recessive or dominant mutations in HEPACAM (also called GLIALCAM) cause MLC type 2A and type
Mutations in the nuclear SURF-1 gene lead directly to cytochrome-c oxidase deficiency, the most common respiratory chain defect in Leigh syndrome, a neurodegenerative mitochondrial disease involving the deep gray matter and brain stem. We describe the second documented case in the literature to have
This report deals with a case of paraproteinemia (IgG Kappa) associated with skin indurations and yellowish papules on the trunk, edema of the face, and crystals in the cornea. In addition to the absence of elastic fibers and reductions of collagen fibers, light microscopy revealed single and/or
Once considered little more than the glue that holds neurons in place, astrocytes are now becoming appreciated for the key roles they play in central nervous system functions. They supply neurons and oligodendrocytes with substrates for energy metabolism, control extracellular water and electrolyte
