In mostly European experience with 69 patients during 1996-2016, the 5- and 10-year survival rates for SCLS patients were 78% and 69%, respectively, but the survivors received significantly more frequent preventive treatment with IVIG than did non-survivors. Five- and 10-year survival rates in patients treated with IVIG were 91% and 77%, respectively, compared to 47% and 37% in patients not treated with IVIG. Moreover, better identification and management of this condition appears to be resulting in lower mortality and improving survival and quality-of-life results as of late.

Due to the risk of crush syndrome, current recommendation to lay first-aiders (in the UK) is to not release victims of crush injury who have been trapped for more than 15 minutes. Treatment consists of not releasing the tourniquet and fluid overloading the patient with added Dextran 4000 iu and slow release of pressure. If pressure is released during first aid then fluid is restricted and an input-output chart for the patient is maintained, and proteins are decreased in the diet.

The Australian Resuscitation Council recommended in March 2001 that first-aiders in Australia, where safe to do so, release the crushing pressure as soon as possible, avoid using a tourniquet and continually monitor the vital signs of the patient. St John Ambulance Australia First Responders are trained in the same manner.

Seigo Minami, a Japanese physician, first reported the crush syndrome in 1923. He studied the pathology of three soldiers who died in World War I from insufficiency of the kidney. The renal changes were due to methemoglobin infarction, resulting from the destruction of muscles, which is also seen in persons who are buried alive. The progressive acute renal failure is because of acute tubular necrosis.

The syndrome was later described by British physician Eric Bywaters in patients during the 1941 London Blitz. It is a reperfusion injury that appears after the release of the crushing pressure. The mechanism is believed to be the release into the bloodstream of muscle breakdown products—notably myoglobin, potassium and phosphorus—that are the products of rhabdomyolysis (the breakdown of skeletal muscle damaged by ischemic conditions).

The specific action on the kidneys is not understood completely, but may be due partly to nephrotoxic metabolites of myoglobin.

The most devastating systemic effects can occur when the crushing pressure is suddenly released, without proper preparation of the patient, causing reperfusion syndrome. In addition to tissue directly suffering the crush mechanism, down stream tissue is subject to Ischemia-reperfusion injuries of the appendicular musculoskeletal system. Without proper preparation, the patient, with pain control, may be cheerful before extrication, but die shortly thereafter. This sudden decompensation is called the "smiling death."

These systemic effects are caused by a traumatic rhabdomyolysis. As muscle cells die, they absorb sodium, water and calcium; the rhabdomyolysis releases potassium, myoglobin, phosphate, thromboplastin, creatine and creatine kinase.

Compartment syndrome can be secondary to crush syndrome. Monitor for the classic 5 Ps: pain, pallor, parasthesias, pain with passive movement, and pulselessness.

Doctors recommend discontinuing the use of phenytoin. The application of heat can help to relieve pain. Oral phenytoin can also result in development of purple glove syndrome.

Although the precise molecular cause of SCLS remains undetermined, scientific research in recent years, conducted mainly at a unit (NIAID) of the U.S. National Institutes of Health, has shed some light on its biological and chemical roots. The study of the peripheral microvasculature from patients’ biopsy specimens has not evidenced gross anomalies, disrupted angiogenesis, or inflammatory cells or other factors suggestive of a disorder prone to damage the blood vessels by inflammation. The absence of structural abnormalities is thus consistent with the hypothesis of some kind of defective but curiously reversible cellular phenomenon in the capillaries.

Studies suggest that the presence of various inflammatory factors during episodes of SCLS may explain the temporarily abnormal permeability of the endothelial cells lining the inner surface of the capillaries. These include transient spikes in monocyte- and macrophage-associated inflammatory mediators and temporary increases in the proteins vascular endothelial growth factors (VEGF) and angiopoietin-2. The impairment of endothelial cells in laboratory conditions provoked by serum taken from patients who were having episodes of SCLS is also suggestive of biochemical factors at work.

There is no evidence that SCLS is hereditary, and the role of specific gene defects in patients with SCLS, which might program their endothelial cells for an overreaction to external stimuli, has not been established. The significance, if any, of the paraprotein (MGUS) present in most patients with SCLS is unknown, other than it has been a precursor to multiple myeloma in a minority (7% in the largest reported cohort) of SCLS patients.

Purple glove syndrome (PGS) is a poorly understood skin disease in which the extremities become swollen, discoloured and painful. PGS is potentially serious, and may require amputation. PGS is most common among elderly patients and those receiving multiple large intravenous doses of the epilepsy drug phenytoin. Compartment syndrome is a complication of PGS.

A compartment syndrome is an increased pressure within a muscular compartment that compromises the circulation to the muscles.

The prognosis depends on the underlying cause and whether any complications occur. Rhabdomyolysis complicated by acute kidney impairment in patients with traumatic injury may have a mortality rate of 20%. Admission to the intensive care unit is associated with a mortality of 22% in the absence of acute kidney injury, and 59% if kidney impairment occurs. Most people who have sustained kidney impairment due to rhabdomyolysis fully recover their kidney function.

A compartment space is anatomically determined by an unyielding fascial (and osseous) enclosure of the muscles. The anterior compartment syndrome of the lower leg (often referred to simply as anterior compartment syndrome), can affect any and all four muscles of that compartment: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius.

This term is often mistakenly used to describe various related/proximal conditions, including Anterior Shin Splints. It is important to distinguish between the two, as shin splints rarely causes serious health problems, while Anterior Compartment Syndrome can lead to irreversible damage.

The true compartment syndrome arises due to increased pressure within the unyielding anterior compartment of the leg. The pressure obstructs venous outflow, which causes further swelling and increased pressure. The resultant ischemia leads to necrosis (death of tissue) of the muscles and nerves. The process can begin with swelling of the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and/or the peroneus tertius muscles in response to strong eccentric contractions sufficient to produce postexercise soreness.

When compartment syndrome is caused by repetitive use of the muscles, it is known as chronic compartment syndrome (CCS). This is usually not an emergency, but the loss of circulation can cause temporary or permanent damage to nearby nerves and muscles.

Complementary to chronic compartment syndrome is another subset known as chronic exertional compartment syndrome CECS, often called exercise induced compartment syndrome EICS. CECS of the leg is a condition caused by exercise which results in increased tissue pressure within a limited fibro-osseous compartment – muscle size may increase by up to 20% during exercise (Touliopolous, 1999). When this happens, pressure builds up in the tissues and muscles causing tissue ischemia (Touliopolous, 1999). An increase in muscle weight will reduce the compartment volume of the surrounding fascial borders and result in an increase of intracompartmental pressure. An increase in the pressure of the tissue can cause fluid to exude into the small spaces between the tissue known as interstitial space, leading to a disruption of the micro-circulation of the leg. This condition occurs commonly in the lower leg and various other locations within the body, such as the foot or forearm. This is commonly seen in athletes who train rigorously in activities that involve constant repetitive actions or motions. In athletic popular culture there is a catchphrase, "Feel the burn," which references these conditions as something to strive for when training, weightlifting or otherwise working out. They are not understood as symptoms. The symptoms involve numbness or a tingling sensation in the area most affected. Other signs and symptoms include pain described as aching, tightening, cramping, sharp, or stabbing. This pain can occur for months, and in some cases over a period of years, and may be relieved by rest. It also includes moderate weakness that can be a noticeable factor in the affected region. Chronic exertional compartment syndrome most commonly affects the anterior compartment of the leg, this can lead to problems with dorsiflexion of the ankle and the toes. The symptoms of CECS are often confused with more common injuries like shin splints and spinal stenosis. Treatment for chronic exertional compartment syndrome includes decreasing or subsiding exercising and activities, or cross training for athletes. In cases with severe intracompartmental pressures surgical treatment, a fasciotomy, is necessary.

The exact number of cases of rhabdomyolysis is difficult to establish, because different definitions have been used. In 1995, hospitals in the U.S. reported 26,000 cases of rhabdomyolysis. Up to 85% of people with major traumatic injuries will experience some degree of rhabdomyolysis. Of those with rhabdomyolysis, 10–50% develop acute kidney injury. The risk is higher in people with a history of illicit drug use, alcohol misuse or trauma when compared to muscle diseases, and it is particularly high if multiple contributing factors occur together. Rhabdomyolysis accounts for 7–10% of all cases of acute kidney injury in the U.S.

Crush injuries are common in major disasters, especially in earthquakes. The aftermath of the 1988 Spitak earthquake prompted the establishment, in 1995, of the Renal Disaster Relief Task Force, a working group of the International Society of Nephrology (a worldwide body of kidney experts). Its volunteer doctors and nurses assisted for the first time in the 1999 İzmit earthquake in Turkey, where 17,480 people died, 5392 were hospitalized and 477 received dialysis, with positive results. Treatment units are generally established outside the immediate disaster area, as aftershocks could potentially injure or kill staff and make equipment unusable.

Acute exertional rhabdomyolysis happens in 2% to 40% of people going through basic training for the United States military. In 2012, the United States military reported 402 cases.

Failure to relieve the pressure can result in necrosis of tissue in that compartment, since capillary perfusion will fall leading to increasing oxygen deprivation of those tissues. This can cause Volkmann's contracture in affected limbs. As intercompartmental pressure rises during compartment syndrome, perfusion within the compartment is reduced leading to ischemia, which if left untreated, results in necrosis of nerves and muscles of the compartment (Shears, 2006). Rhabdomyolysis and subsequent renal failure are also possible complications.

Minimal change disease is most common in very young children but can occur in older children and adults. It is by far the most common cause of nephrotic syndrome in children between the ages of 1 and 7, accounting for the majority (about 90%) of these diagnoses. Among teenagers who develop nephrotic syndrome, it is caused by minimal change disease about half the time. It can also occur in adults but accounts for less than 20% of adults diagnosed with nephrotic syndrome. Among children less than 10 years of age, boys seem to be more likely to develop minimal change disease than girls. Minimal change disease is being seen with increasing frequency in adults over the age of 80.

People with one or more autoimmune disorders are at increased risk of developing minimal change disease. Having minimal change disease also increases the chances of developing other autoimmune disorders.

The major cause of acute limb ischaemia is arterial thrombosis (85%), while embolic occlusion is responsible for 15% of cases. In rare instances, arterial aneurysm of the popliteal artery has been found to create a thrombosis or embolism resulting in ischaemia.

In the absence of severe urinary tract obstruction (which generally requires surgery with omental wrapping), treatment is generally with glucocorticoids initially, followed by DMARDs either as steroid-sparing agents or if refractory on steroids. The SERM tamoxifen has shown to improve the condition in various small trials, although the exact mechanism of its action remains unclear.

Associations include:

- Riedel's thyroiditis

- previous radiotherapy

- sarcoidosis

- inflammatory abdominal aortic aneurysm

- drugs

Protein tyrosine phosphatase receptor type O, also known as glomerular epithelial protein 1 (GLEPP1), has been shown to be mutated in a number of cases.

Abdominal compartment syndrome occurs when the abdomen becomes subject to increased pressure. Specific cause of abdominal compartment syndrome is not known, although some causes can be sepsis and severe abdominal trauma. Increasing pressure reduces blood flow to abdominal organs and impairs pulmonary, cardiovascular, renal, and gastro-intestinal (GI) function, causing multiple organ dysfunction syndrome and death.

Until recently, the medical literature did not indicate a connection among many genetic disorders, both genetic syndromes and genetic diseases, that are now being found to be related. As a result of new genetic research, some of these are, in fact, highly related in their root cause despite the widely varying set of medical symptoms that are clinically visible in the disorders. Ellis–van Creveld syndrome is one such disease, part of an emerging class of diseases called ciliopathies. The underlying cause may be a dysfunctional molecular mechanism in the primary cilia structures of the cell, organelles which are present in many cellular types throughout the human body. The cilia defects adversely affect "numerous critical developmental signaling pathways" essential to cellular development and thus offer a plausible hypothesis for the often multi-symptom nature of a large set of syndromes and diseases. Known ciliopathies include primary ciliary dyskinesia, Bardet–Biedl syndrome, polycystic kidney and liver disease, nephronophthisis, Alstrom syndrome, Meckel–Gruber syndrome and some forms of retinal degeneration.

Weyers acrofacial dysostosis is due to another mutation in the EVC gene and hence is allelic with Ellis–van Creveld syndrome.

Smoking does not directly cause high blood pressure. However it is a known risk factor for other serious cardiovascular disease.

Ellis–van Creveld syndrome often is the result of founder effects in isolated human populations, such as the Amish and some small island inhabitants. Although relatively rare, this disorder does occur with higher incidence within founder-effect populations due to lack of genetic variability. Observation of the inheritance pattern has illustrated that the disease is autosomal recessive, meaning that both parents have to carry the gene in order for an individual to be affected by the disorder.

Ellis–van Creveld syndrome is caused by a mutation in the "EVC" gene, as well as by a mutation in a nonhomologous gene, "EVC2", located close to the EVC gene in a head-to-head configuration. The gene was identified by positional cloning. The EVC gene maps to the chromosome 4 short arm (4p16). The function of a healthy EVC gene is not well understood at this time.

Acute uric acid nephropathy (AUAN) due to hyperuricosuria has been a dominant cause of acute kidney failure but with the advent of effective treatments for hyperuricosuria, AUAN has become a less common cause than hyperphosphatemia. Two common conditions related to excess uric acid, gout and uric acid nephrolithiasis, are not features of tumor lysis syndrome.

Abdominal compartment syndrome occurs when tissue fluid within the peritoneal and retroperitoneal space (either edema, retroperitoneal blood or free fluid in the abdomen) accumulates in such large volumes that the abdominal wall compliance threshold is crossed and the abdomen can no longer stretch. Once the abdominal wall can no longer expand, any further fluid leaking into the tissue results in fairly rapid rises in the pressure within the closed space. Initially this increase in pressure does not cause organ failure but does prevent organs from working properly - this is called intra-abdominal hypertension and is defined as a pressure over 12 mm Hg in adults. However, if the pressure continues to rise over 20 mm Hg and organs begin to fail, the syndrome has now progressed to the end stage of the highly fatal process termed abdominal compartment syndrome. These pressure measurements are relative. Small children get into trouble and develop compartment syndromes at much lower pressures while young previously healthy athletic individuals may tolerate an abdominal pressure of 20 mm Hg very well.

The underlying cause of the disease process is capillary permeability caused by the systemic inflammatory response syndrome (SIRS) that occurs in every critically ill patient. SIRS leads to leakage of fluid out of the capillary beds into the interstitial space in the entire body with a profound amount of this fluid leaking into the gut wall, mesentery and retroperitoneal tissue. (For a much more extensive discussion on the topic and physiology visit the Wikipedia section discussing intra-abdominal hypertension.)

- Peritoneal tissue edema secondary to diffuse peritonitis, abdominal trauma

- Fluid therapy due to massive volume resuscitation

- Retroperitoneal hematoma secondary to trauma and aortic rupture

- Peritoneal trauma secondary to emergency abdominal operations

- Reperfusion injury following bowel ischemia due to any cause

- Retroperitoneal and mesenteric inflammatory edema secondary to acute pancreatitis

- Ileus and bowel obstruction

- Intraabdominal masses of any cause

- Abdominal packing for control of bleeding

- Closure of the abdomen under undue tension

- Ascites / intraabdominal fluid accumulation

- Acute pancreatitis with abscesses formation

Abdominal compartment syndrome follows a destructive pathway similar to compartment syndrome of the extremities. When increased compression occurs in such a hollow space, organs will begin to collapse under the pressure. As the pressure increases and reaches a point where the abdomen can no longer be distended it starts to affect the cardiovascular and pulmonary systems. When abdominal compartment syndrome reaches this point without surgery and help of a silo the patient will most likely die. There is a high mortality rate associated with abdominal compartment syndrome.

Risk factors for tumor lysis syndrome depend on several different characteristics of the patient, the type of cancer, and the type of chemotherapy used.

Tumor Characteristics: Tumors with a high cell turnover rate, rapid growth rate, and high tumor bulk tend to be more associated with the development of tumor lysis syndrome. The most common tumors associated with this syndrome are poorly differentiated lymphomas (such as Burkitt's lymphoma), other Non-Hodgkin Lymphomas (NHL), acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), and chronic myelogenous leukemia (CML). Other cancers (such as melanoma) have also been associated with TLS but are less common.

Patient Characteristics: Certain patient-related factors can affect the development of clinical tumor lysis syndrome. These factors include elevated baseline serum creatinine, renal insufficiency, dehydration, and other issues affecting urinary flow or the acidity of urine.

Chemotherapy Characteristics: Chemo-sensitive tumors, such as lymphomas, carry a higher risk for the development of tumor lysis syndrome. Those tumors that are more responsive to a chemotherapy agent carry a higher TLS risk. Usually, the precipitating medication regimen includes combination chemotherapy, but TLS can be triggered in cancer patients by steroid treatment alone, and sometimes without any treatment—in this case the condition is referred to as "spontaneous tumor lysis syndrome".

The best course of treatment varies from case to case. The physician must take into account the details in the case before deciding on the appropriate treatment. No treatment is effective for every patient.

Treatment depends on many factors, including:

- Location of lesions

- Anatomy of lesions

- Patient risk factors

- Procedural risk

- Clinical presentation of symptoms

- Duration of symptoms

- etc.

Excessive alcohol consumption will increase blood pressure over time. Alcohol also contains a high density of calories and may contribute to obesity.
