A MELAS Patient Developing Fatal Acute Renal Failure with Lactic Acidosis and Rhabdomyolysis.

We herein present a patient with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS), who developed serious acute renal failure with lactic acidosis, followed by rhabdomyolysis. Despite receiving intensive care, he suffered multiple cardiopulmonary arrests and died 10 days after presentation due to a sudden deterioration of his symptoms. Renal pathology revealed diffuse tubular necrosis with interstitial edema and tubular dilatation on light microscopy, and a severe degeneration of intracellular organelles on electron microscopy.

An Autopsy Case of Amyotrophic Lateral Sclerosis with Diaphragm Pacing.

Respiratory insufficiency is a critical problem in amyotrophic lateral sclerosis (ALS) patients. We herein present the case of an autopsied patient with sporadic ALS who underwent diaphragm pacing (DP). The pathology showed several localized adhesions with a markedly atrophied diaphragm.
