چکیده

We present a boy of eight years of age with symptoms of Kearns-Sayre syndrome (KSS) characterised by ophthalmoparesis, palpebral ptosis, mitochondrial myopathy, pigmentous retinitis, associated to short stature, cerebellar signs, cardiac blockade, diabetes mellitus, elevated cerebrospinal fluid protein concentration, and focal hand and foot dystonia. The skeletal muscle biopsy demonstrated ragged red fibers, cytochrome C oxidase-negative and succinate dehydrogenase-positive fibers. The magnetic resonance imaging showed symmetrical signal alteration in tegmentum of brain stem, pallidum and thalamus. Mitochondrial DNA analysis from skeletal muscle showed a deletion in heteroplasmic condition. The association of dystonia to KSS, confirmed by molecular analysis, is first described in this case, and the importance of oxidative phosphorylation defects in the physiopathogenesis of this type of movement disorder is stressed.

Hypoparathyroidism as the First Mani-Festation of Kearns-Sayre Syndrome: A Case Report

Kearns-Sayre syndrome is a mitochondrial myopathy, which was first described by Tomas Kearn in 1958. Diagnostic symptoms of this condition include retinitis pigmentosa, chronic progressive external ophthalmoplegia, and one or more of the following factors: cardiac conduction system diseases, cerebellar ataxia, and cerebrospinal fluid (CSF) with protein content above 100 mg/dL. The nature of thi...

Hypoparathyroidism as the First Manifestation of Kearns-Sayre Syndrome: A Case Report

OBJECTIVE Kearns-Sayre syndrome is a mitochondrial myopathy, which was first described by Tomas Kearn in 1958. Diagnostic symptoms include retinitis pigmentosa, chronic and progressive external ophthalmoplegia plus one or more of following factors: heart conduction system disorders, cerebellar ataxia, or cerebrospinal fluid (CSF) protein content above 100 mg/dL. The nature of this uncommon dise...

[Cardiac involvement in Kearns-Sayre syndrome].

The mitochondrial cytopathies or oxidative-phosphorylation diseases are a diverse group of disorders that result from the structural, biochemical, or genetic derangement of mitochondria. Because mitochondrial dysfunction can affect the most highly energy-dependent organs, cardiac involvement is frequent in these diseases. To identify the clinical features of Kearns-Sayre syndrome, an entity ass...

[PCR-based detection of heteroplasmic deleted mitochondrial DNA in Kearns-Sayre syndrome].

OBJECTIVE To describe the clinical data and the results of molecular analyses of the mitochondrial DNA in a patient with Kearns-Sayre Syndrome. METHODS Molecular analyses of mitochondrial DNA from the patient included PCR amplification of a region where the common Kearns- Sayre deletion is located and Genotype-Phenotype correlations are discussed. RESULTS The affected patient showed ptosis,...
