Rhabdomyolysis Symptoms and CausesWhat Is the Definition of Rhabdomyolysis, and What Are the Symptoms and Causes?Rhabdomyolysis is a condition in which skeletal muscle cells break down, releasing myoglobin (the oxygen-carrying pigment in muscle) together with enzymes and electrolytes from inside the muscle cells. The risks with rhabdomyolysis include muscle breakdown and kidney failure since myoglobin is toxic to the kidneys. Rhabdomyolysis can occur from extensive muscle damage as, for example, from a crushing injury or an electrical shock. Drugs or toxins, particularly some of the cholesterol lowering medications from the class of drugs called "statins," may cause this disorder. Underlying diseases such as systemic lupus erythematosus can also lead to rhabdomyolysis. It is a common complication of major burns. The key signs and symptoms of rhabdomyolysis include:
SOURCE: Medterms.com. Rhabdomyolysis. Rhabdomyolysis OverviewRhabdomyolysis is a condition that may occur when muscle tissue is damaged due to an injury in which muscle in the body is damaged (rhabdomyo=skeletal muscle + lysis= rapid breakdown). There are a three of types of muscle in the body, including:
Rhabdomyolysis occurs when there is damage to the skeletal muscle. The injured muscle cell leaks myoglobin (a protein) into the blood stream. Myoglobin can be directly toxic to kidney cells, and it can impair and clog the filtration system of the kidney. Both mechanisms can lead to kidney failure (the major complication of rhabdomyolysis). Significant muscle injury can cause fluid and electrolyte shifts from the bloodstream into the damaged muscle cells, and in the other direction (from the damaged muscle cells into the bloodstream). As a result, dehydration may occur. Elevated levels of potassium in the bloodstream (hyperkalemia) may be associated with heart rhythm disturbances and sudden cardiac death due to ventricular tachycardia and ventricular fibrillation. Complications of rhabdomyolysis also include disseminated intravascular coagulation, a condition that occurs when small blood clots begin forming in the body's blood vessels. These clots consume all the clotting factors and platelets in the body, and bleeding begins to occur spontaneously. When muscles are damaged, especially due to a crush injury, swelling within the muscle can occur, causing compartment syndrome. If this occurs in an area where the muscle is bound by fascia (a tough fibrous tissue membrane), the pressure inside the muscle compartment can increase to the point at which blood supply to the muscle is compromised and muscle cells begin to die. Rhabdomyolysis was first appreciated as a significant complication from crush and blast injuries sustained in a volcano eruption in Italy, in 1908. Victims of the blast injuries during the first and second World Wars help further understand the relationship between massive muscle damage and kidney failure.

Black Widow Spider Bite Overview
Of the 30,000 types of spiders, the black widow is probably the one best known and feared. Although spiders are often blamed for all kinds of symptoms, from local itching to diffuse rashes, the fact is that spiders rarely bite humans, and in fact, most spider bites do not even break the skin.
The bites of very large spiders such as tarantulas can be painful. Otherwise, in the temperate regions, the only spiders to be feared are the black widow and the brown recluse.
- The black widow is a medium-sized spider whose body is about a half-inch long. The name is derived from the mistaken belief that the female invariably kills the male after mating. Although the spider is mostly found in the southern
United States, it may be seen throughout the US. Five species are common to the US, with two of them being the most common:
- The southern black widow has the shiny, black, globular abdomen with the...
