Lactic acidosis with necrotizing encephalopathy in two sibs.

Encephalopathy, Lactic Acidosis, and Strokelike Episodes

Background and Purpose: The precise mechanism of neurological symptoms with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS) is still controversial. We investigated the correlation between strokelike episodes and cerebral blood flow in two patients with MELAS and discuss the pathogenesis of strokelike episodes with MELAS. Summary of Report: Cerebral dynam...

Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS).

We report the clinical, pathological, and genetic findings of a case of MELAS syndrome. This was a man who died for metabolic failure at the age of 27 years. His familiar history was positive for hypoacusia and stroke. He was of short stature and presented mild mental retardation. Since the age of 21 he suffered from recurrent brain-ischemic lesions mainly in the occipital lobes, documented by ...

Lactic Acidosis

Lactic acidosis is a form of metabolic acidosis due to the inadequate clearance of lactic acid from the blood. Lactate is a byproduct of anaerobic respiration and is normally cleared from the blood by the liver, kidney and skeletal muscle. Lactic acidosis occurs when the body's buffering systems are overloaded and tends to cause a pH of ≤7.25 with plasma lactate ≥5 mmol/L. It is usually caused ...

Lactic acidosis associated with propofol.

Lactic acidosis.

A 33-year-old male was admitted to Michael Reese Hospital and Medical Center for evaluation of weight loss, dyspnea, and fever. He had factor Vill-deficient hemophilia and had been chronically ill over several months with a cough productive of scanty sputum, weight loss of 15 Ibs, low-grade fever, and progressive dyspnea on exertion. The medical history was notable for right total hip replaceme...
