Very little is known about tissue changes and pathophysiological mechanisms in Garin-Boujadoux-Bannwarth syndrome. We report histopathological findings in the central and peripheral nervous systems of three typical cases. In the acute stage of the disease mononuclear perivascular infiltrations with mainly T-helper cells were the prominent finding, whereas(More)
Kearns-Sayre syndrome has been associated with large heteroplasmic mitochondrial DNA deletions and morphological alterations at the cytological level. We have measured the activities of different respiratory chain complexes in 3 patients presenting mitochondrial DNA deletions and found no close correlation between gene deletions and enzymatic activities.(More)

We report on the progression of myopathology by comparing two biopsies from a patient with a Kearns-Sayre-Syndrome. The first biopsy was taken in 1979 and showed 10% ragged-red fibers. Myopathic changes were slight including internal nuclei and fiber splitting in 10% of the fibers. Electron microscopy revealed typical mitochondrial abnormalities with regard(More)
In standard concentric needle electromyography the typical triphasic potential of a motor unit (MUP) consists of the spike component and the positive initial and terminal parts. Whereas the main spike is generated by a few muscle fibers located close to the tip of an electrode, the initial and terminal parts represent the sum of activities of a large(More)
