Diabetic myonecrosis in end-stage renal disease

Diabetic myonecrosis or muscle infarction (DMI), a clinicoradiological entity is an underdiagnosed complication of diabetes mellitus. It refers to spontaneous aseptic necrosis of skeletal muscles commonly of the lower limb without evidence of any large vessel disease. It presents as painful swollen limb without any external insult in patients with long-standing diabetes mellitus with other microvascular complications especially nephropathy. We present four instances of DMI in our patients who had end-stage renal disease with a varied course.

Critical illness polyneuropathy: how often do we diagnose it?

Neuromuscular weakness in critically ill patients is a diagnostic challenge. Critical illness polyneuropathy, an important cause of failure to wean from assisted ventilation is often missed due to lack of suspicion and initiative to undertake regular bedside neurological and electrophysiological examinations in critically ill patients. We report two cases who developed motor weakness while receiving mechanical ventilation in whom axonal neuropathy was diagnosed on electrophysiological studies, establishing a diagnosis of critical illness polyneuropathy. Both patients had evidence of sepsis and multiorgan failure. One case could be successfully weaned off and weakness improved while other succumbed to the underlying illness.
