On electron microscopy, the abnormal mitochondria present on the first biopsy specimen had disappeared both in muscle fibers and blood vessels; nearly all mitochondria were morphologically normal at the second biopsy. [ncbi.nlm.nih.gov]

The abnormal muscle and mitochondrial morphology in a variety of clinical presentations from isolated ophthalmoplegia to severe encephalopathy are also elaborated. [books.google.com]

However, while the mechanism of action of GCs in the treatment of MIDs remains largely unknown, there are indications that GCs act not only in the nucleus but also in mitochondria.( 3, 4 ) Herein, we summarise and discuss the role of GCs in the treatment [smj.org.sg]

Most of the gene defects in this group of patients remain unknown and there are no effective treatments. [ncl.ac.uk]

This study provides the rationale for a simple genetic test to identify infants with mitochondrial myopathy and good prognosis. [f1000.com]

Neonatal cardiomyopathies commonly are associated with poor prognosis, and the underlying etiology of this disorder differs considerably from cardiomyopathies in older children, adolescents, and adults with similar phenotypes. [journals.lww.com]

Mitochondrial myopathies generally have a bad prognosis. But recently Horvath et al., 20 have described the genetics of a rare but strangely, relatively benign form of mitochondrial myopathy.” [medcraveonline.com]

This simple genetic test is of critical importance for prognosis and management of these infants because the benign form is initially life threatening but ultimately reversible. [mafiadoc.com]
