[...] October 22, 2010 — Progressive supranuclear palsy (PSP) is a degenerative neurological disorder of uncertain etiology characterized by gait ataxia, slowing or inability to generate voluntary saccadic eye movements, and axial rigidity. The most characteristic aspect of PSP is an inability to move the eyes, but the first symptom of PSP is usually unsteadiness and falling. (Click for more details) (Click for more details) [...]

Comment on Duchenne muscular dystrophy by Role of neuroimaging in muscular dystrophy « Online newspaper of professor Yasser Metwally

[...] February 27, 2010 — Genetic testing has revolutionized the evaluation of muscular dystrophy. Many forms of muscular dystrophy now can be diagnosed with noninvasive testing (Box 1). Myoclonic epilepsy and ragged-red fibers (MERRF) and mitochondrial myopathy, encephalopathy, lactic acid, and strokes (MELAS) are considered by some to be muscle diseases and also can be diagnosed by genetic testing. These conditions are considered better as multisystem cytopathies, however. These conditions vary widely in their signs and symptoms (Box 2). The diagnosis of other types of muscular dystrophy still is dependent on muscle biopsy (Table 1). One notable exception is cases of dystrophinopathy with normal genetic testing. Approximately 65% of cases of dystrophinopathy are the result of gene deletions and approximately 5% are the result of duplications [1–3]. The result of these mutations is a loss or truncation of the reading frame. These mutations easily are detected by Southern blot analysis. The remainder of the mutations is the result of point mutations that result in a premature central codon [4–5]. These mutations generally are not detected by Southern blot analysis or routine PCR-based testing. Although many point mutations can be detected in research laboratories, such testing is more expensive and time consuming and thus not always available for the dystrophinopathies. Single-strand conformation polymorphism analysis and denaturing high-performance liquid chromatography have been used to increase the sensitivity of genetic testing in approximately 90% of cases [5,6].
