Acute Tubular Necrosis

The causes of acute renal failure (ARF) are conventionally and conveniently divided into 3 categories: prerenal, renal, and postrenal. Prerenal ARF involves an essentially normal kidney that is responding to hypoperfusion by decreasing the glomerular filtration rate (GFR). Renal, or intrinsic, ARF refers to a condition in which the pathology lies within the kidney itself. Postrenal failure is caused by an obstruction of the urinary tract. Acute tubular necrosis (ATN) is the most common cause of ARF in the renal category.

Myelomalacia is the softening or necrosis of the spinal cord after an acute injury.

Fat necrosis is one of many types of necrosis. Necrosis is cell death with inflammation (different from apoptosis, which is without inflammation).

Fat necrosis occurs in two forms.

1. Traumatic fat necrosis is the result of trauma. Cellular damage to fat-rich organs, such as the breasts, can lead to necrosis of the adipocytes.

2. Fat necrosis as a result of acute haemorrhagic pancreatitis. In this case, damage to the pancrease releases lipolytic enzymes into the blood, causing damage, and eventual necrosis of adipocytes.
