Hyperemesis gravidarum (from Greek hyper and Latin emesis and gravida; meaning "excessive vomiting of pregnant women") is a severe form of morning sickness, with unrelenting, excessive pregnancy-related nausea and/or vomiting that prevents adequate intake of food and fluids. Hyperemesis is considered a rare complication of pregnancy but, because nausea and vomiting during pregnancy exist on a continuum, there is no clear boundary between common morning sickness and hyperemesis. Estimates of the percentage of pregnant women afflicted range from 0.3% to 2%. ...

Myoglobinuria is the presence of myoglobin in the urine, usually associated with rhabdomyolysis or muscle destruction. Myoglobin is present in muscle cells as a reserve of oxygen. Trauma, vascular problems, venoms, certain drugs and other situations can destroy or damage the muscle, releasing myoglobin to the circulation and thus to the kidneys. Under ideal situations myoglobin will be filtered and excreted with the urine, but if too much myoglobin is released into the circulation or in case of renal problems, it can occlude the renal filtration system leading to acute tubular necrosis and acute renal insufficiency.It should be noted that information from the Pfizer pharmaceuticals web site states "rare cases of rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with ATORVASTATIN and with other drugs in its class." "It is recommended that liver function tests be performed prior to and at 12 weeks following the initiation of this drug theraphy" For the uninitiated "Atorvastatin" is the most widly prescribed drug used to control cholesterol levels in humans. ...

Acute renal failure (ARF) is a rapid loss of renal function due to damage to the kidneys, resulting in retention of nitrogenous (urea and creatinine) and non-nitrogenous waste products that are normally excreted by the kidney. Depending on the severity and duration of the renal dysfunction, this accumulation is accompanied by metabolic disturbances, such as metabolic acidosis (acidification of the blood) and hyperkalaemia (elevated potassium levels), changes in body fluid balance, and effects on many other organ systems. It can be characterised by oliguria or anuria (decrease or cessation of urine production), although nonoliguric ARF may occur. It is a serious disease and treated as a medical emergency. ...

Rhabdomyolysis is the rapid breakdown of skeletal tissue due to traumatic injury, either mechanical, physical or chemical. The principal result is a large release of the CPK enzymes and other cell byproducts into the blood system and acute renal failure due to accumulation of muscle breakdown products, several of which are injurous to the kidney. Treatment is with intravenous fluids, and dialysis if necessary. ...

The syndrome of inappropriate antidiuretic hormone (SIADH) is a condition commonly found in the hospital population, especially in patients being hospitalized for central nervous system (CNS) injury. As the name states, this is a syndrome characterized by excessive release of antidiuretic hormone (ADH or vasopressin) from the posterior pituitary gland or another source. The result is hyponatremia, and sometimes fluid overload. ...
