Extractions: Received: 1 October 1997 / Accepted: 11 March 1998 Abstract Kearns Sayre syndrome (KSS) is a multisystem disorder with a confounding variety of clinical manifestations, including ocular myopathy, pigmentary retinopathy, heart block and ataxia. Endocrinopathies are common in KSS, including growth hormone deficiency, hypogonadism, diabetes mellitus and hypoparathyroidism. A variety of deletions of mitochondrial DNA (mtDNA) are found in most cases. We report on a 5-year-old boy with Addison disease in whom further investigation revealed a 4.9 kilobase mtDNA deletion and KSS. Later he developed severe lactic acidosis and expired. Conclusion The degree of mutant mtDNA heteroplasmy in various tissues on autopsy did not correlate well with the clinical manifestations, although this may be due at least in part to replacement with other tissue types. Our report is the first of non-autoimmune Addison disease in KSS and patients with KSS should be evaluated for adrenal insufficiency. Early recognition of adrenal insufficiency is crucial to prevent mortality from this cause.

It is characterized by progressive external ophthalmoplegia (paralysis of the eye muscles) and mild skeletal muscle weakness. It may also be associated with other manifestations such as retinal pigmentation (abnormal accumulation of pigmented material on the membrane lining the eyes), cardiac conduction defects, short stature, hearing loss, increased cerebrospinal fluid protein, inability to coordinate voluntary movements (ataxia), impaired cognitive dysfunction, diabetes, and other endocrine disorders.
Extractions: Complete Atrioventricular Block in Kearns-Sayre Syndrome Universidade Federal Fluminense-UFF - Rio de Janeiro, RJ Arquivos Brasileiros de Cardiologia 67(2):, 1996 Full paper in portuguese A thirty-three year old woman, known to have Kearns-Sayre syndrome for eight years, had an ECG pattern of right bundle branch block and left anterior fascicular block that evolved to complete atrioventricular block, leading her to have a syncopal episode. A temporary pacemaker and then a permanent one were installed. The patient has been asymptomatic so far. Summary
Extractions: These patients frequently present with ptosis, ophthalmoplegia and mitochondrial myopathy. Severe cases have onset before 20 years of age and also manifest retinitis pigmentosa and a least one of the following: cardiac conduction defects, cerebellar ataxia, or elevated CSF protein above 100 mg/dl. Approximately 83% of KSS and 47% of CPEO patients carry mitochondrial DNA rearrangements detectable by southern analysis. A great majority of these rearrangements are new mutations. Therefore, the patients are heteroplasmic for normal and rearranged mitochondrial DNA molecules. The remainder of cases result from a variety of point mutations. Since mutant mitochondrial DNA molecules may be undetectable in blood cells due to replicative segregation, analysis of muscle biopsy may be necessary if the blood sample is negative for rearrangements or mutations. Blood 5-10 ml whole blood in an EDTA ( purple top ) or ACD ( yellow top ) tube.

In addition, KSS may include cardiac conduction defects, cerebellar ataxia, and raised cerebrospinal fluid (CSF) protein levels (>100 mg/dL). Additional features associated with KSS may include myopathy, dystonia, endocrine abnormalities (eg, diabetes, growth retardation/short stature, hypoparathyroidism), bilateral sensorineural deafness, dementia, cataracts, and proximal renal tubular acidosis. Thus, KSS may affect many organ systems. Pathophysiology: KSS occurs secondary to deletions in mitochondrial DNA (mtDNA) that cause a particular phenotype. The gene in which deletions occur is identified as Online Mendelian Inheritance in Man number 530000. An understanding of some aspects of mitochondrial genetics is important to understanding KSS.

Patients usually experience bilateral, symmetrical, progressive ptosis, followed by ophthalmoparesis months to years later. Ciliary and iris muscles are not involved. CPEO is the most frequent manifestation of mitochondrial myopathies. CPEO in association with mutations in mitochondrial DNA (mtDNA) may occur in the absence of any other clinical sign, but usually it is associated with skeletal muscle weakness. Kearns-Sayre syndrome (KSS) is a related mitochondrial myopathy that demonstrates the following: CPEO, onset before age 20, and pigmentary retinopathy. KSS also has at least one of the following: cardiac conduction defects, cerebrospinal fluid (CSF), protein of greater than 100 mg/dL, and a cerebellar syndrome. Other abnormalities in KSS can include mental retardation, Babinski sign, hearing loss, seizures, short stature, delayed puberty, and various endocrine disorders. CPEO also can be a sign in the following disorders: oculopharyngeal dystrophy, myasthenia gravis, and Graves disease.
