Aortic rupture as a result of low velocity crush. (1/40)
A case of aortic disruption in a 35 year old lorry driver is described. This occurred as a result of a low velocity crushing force. Clinicians should be aware that this mechanism of injury may result in aortic disruption as well as the more commonly mentioned severe deceleration force.

The Recompression Treatment Centre on Stonecutters Island has been operating in Hong Kong for more than 5 years and has been used to treat a variety of diving-related and other conditions by means of hyperbaric oxygen therapy. Up to the end of December 1997, 295 treatment sessions had been conducted for 39 patients. This article reviews the usefulness of and indications for hyperbaric oxygen therapy. (+info)Intervention of the Renal Disaster Relief Task Force in the 1999 Marmara, Turkey earthquake. (3/40)
BACKGROUND: Major earthquakes are followed by a substantial number of crush syndromes and pigment-induced acute renal failures (ARFs). The natural evolution of this problem rapidly leads to death. Today's possibilities of dialysis therapy enable saving numerous lives that otherwise would be lost. Currently, the primary problem is organizational, if huge catastrophes occur and complex therapeutic options need to be offered to a large number of victims. METHODS: Following the 1988 Spitak earthquake in Armenia, the International Society of Nephrology (ISN) established the Renal Disaster Relief Task Force (RDRTF) in order to anticipate organizational problems related to renal care in the aftermath of large natural and human-made catastrophes. The proposed concept was one of a dialysis advance team, which would assess the needs and possibilities of dialysis treatment, to be followed by supportive manpower and supplies. This article describes the organizational aspects of a rescue action that was undertaken following the Marmara earthquake, which occurred on August 17th, 1999, in northwestern Turkey. In conjunction with Medecins Sans Frontieres, a team landed at Istanbul Airport less than 22 hours after the disaster, and logistic and material support as well as manpower were provided over a period of approximately one month. Specific attention was paid to the choice of the renal replacement therapy, the transport of victims and materials, the implementation of preventive rehydration, and the problem of chronic renal failure patients dialyzed in the damaged area. CONCLUSIONS: We demonstrate how previously anticipated international support may offer moral, financial, as well as logistical help to local nephrological communities confronted with serious disasters. (+info)Birth trauma to muscles in babies born by breech delivery and its possible fatal consequences. (4/40)
Dissection and histological examination was made of the muscles of 86 babies who died after breech delivery, and of 38 babies who died after vertex presentation. A control group of 50 surviving breech-delivered babies was examined clinically and the results compared. It was concluded that the most common type of birth trauma to a baby born by breech delivery is injury to muscles and soft tissues of the back and lower extremities, which is often extensive. In some severly injured babies histological examination of organs revels signs of crush syndrome and disseminated intravascular coagulation. It is suggested that the extensive muscle trauma forms the background of these fatal conditions. (+info)The Marmara earthquake: epidemiological analysis of the victims with nephrological problems. (5/40)
BACKGROUND: Crush syndrome resulting from earthquakes is a major cause of morbidity and mortality, as seen during the catastrophic Marmara earthquake that struck Northwestern Turkey in August 1999. This report analyzes the epidemiological characteristics of the crush syndrome victims of this disaster. METHODS: In order to analyze the nephrological problems caused by this earthquake, questionnaires were prepared within the first week of the disaster and sent to 35 reference hospitals that treated the victims. Data obtained by these questionnaires are the subject of this report. RESULTS: Of the 5302 hospitalized patients in reference hospitals, 639 (12.0%) suffered from nephrological problems, and 477 (9.0%) needed dialysis support. Considering the patients with renal problems, there was not any significant difference in gender; however, the incidence of children younger than 10 years and the older population (older than 60 years of age) was significantly lower as compared with the resident population of the affected area (P < 0.001). Nonsurvivors were older (34.5 +/- 16.1 years) than survivors (31.2 +/- 14.4 years, P = 0.048), while no deaths were recorded under the age of 10. Most patients (70.1%) were admitted within the first three days after the earthquake, and the mortality rate among these victims was higher (17.7%) as compared with victims admitted thereafter (10.0%, P = 0.016). The average time period under the rubble was 11.7 +/- 14.3 hours, which was not significantly different between survivors and nonsurvivors, while the victims who required dialysis support spent shorter durations under the rubble, as compared with the ones who were not dialyzed at all (10.3 +/- 9.5 vs. 15.9 +/- 23.1 hours, P < 0.001). CONCLUSION: Victims of catastrophic earthquakes are characterized by a high incidence of renal problems and the need for dialysis support. The incidence of nephrological problems is lower in children, while the period of time under the rubble is not a prognostic indicator of survival. (+info)Moorgate tube train disaster. Part II. Clinicopathological review. (6/40)
A review of the injuries sustained by the 113 casualties of the Moorgate tube train disaster has shown the need for rapid evacuation of casualties. Recognition of the "crush syndrome" and its early consequence, hyperkalaemia, is important and a radical surgical approach is suggested. Chest injuries were common and contributed to many of the deaths. (+info)An overview of morbidity and mortality in patients with acute renal failure due to crush syndrome: the Marmara earthquake experience. (7/40)
BACKGROUND: On August 17, 1999 a major earthquake hit the most densely populated area at the eastern end of the Marmara Sea in northwestern Turkey. The number of documented cases of acute renal failure (ARF) following this event exceeded all similar cases previously reported for any single earthquake. The aim of this report was to provide an overview of the morbidity and mortality of all documented patients with ARF, due to crush injury, that were treated in hospitals with dialysis units following the Marmara earthquake. METHODS: Special questionnaires were sent out to all hospitals with dialysis units known to have admitted earthquake victims with ARF and related crush injuries. Responses to questionnaires from the Turkish Society of Nephrology (TSN) Task Force were collected from 35 hospitals in October 1999. We retrospectively evaluated patients, clinic and laboratory findings, surgical interventions, and frequency and duration of dialysis. Patients who died before or on admission and those with prior chronic renal disease were excluded from the study. RESULTS: A total of 639 patients (291 female and 348 male) with ARF due to crush injury were hospitalized in 35 hospitals. The mean age was 31.6+/-14.7 years and 71.1% were young adults within the range of 16-45 years. 477 patients (74.6%) received one or more dialysis treatments, 162 patients were not dialysed, 15 patients died before dialysis could be instituted, and 147 patients recovered without dialysis treatment. 340 patients were oliguric on admission. The most important abnormalities related to ARF as a result of crush injury morbidity, were oliguria (53.2%), uraemia (94%), high creatinine levels (87%), hyperkalaemia (42%), hyperphosphataemia (63%), hypocalcaemia (83%), and high creatinine phosphokinase levels (73 %). 512 patients had a total of 790 extremity injuries. Eighty-three patients (12.9%) had fractures of the extremities and non-extremity fractures were observed in 59 (9.2%) patients. 323 fasciotomies were performed. Thoracic and abdominal trauma was observed in 110 patients (17.2%). Infection and sepsis were observed in 223 (34.9%) and 121 (18.9%) patients, respectively. Haematologic abnormalities were observed in 197 patients (33%) including 116 with Htc < or =30%. There were pulmonary problems in 96 patients (15%), cardiovascular problems in 198 patients (30.9%), gastrointestinal problems in 23 (3.16%), neurologic problems in 43 (6.7%), and psychiatric problems in 7 (1%) patients. Ninety-seven of the 639 patients with ARF as a result of crush injury died (15.2%), and mortality rates were 17.2 and 9.3% in dialysed and non-dialysed patients, respectively. Findings significantly associated with mortality were sepsis, thrombocytopenia, disseminated intravascular coagulation (DIC), acute respiratory distress syndrome (ARDS), and abdominal and thoracic traumas. CONCLUSIONS: We conclude that in cases of severe disasters such as major earthquakes, patients should be rapidly transferred to undamaged peripheral general hospitals. When proper dialysis and intensive care facilities together with around the clock dedicated human effort are available, crush injury-related ARF patients have a lower mortality. Mortality, when it occurs, is mainly associated with thoracic and abdominal trauma and medical problems such as DIC and/or ARDS/respiratory failure, often in conjunction with sepsis. (+info)Improving ischaemic skin revascularisation by nerve growth factor in a child with crush syndrome. (8/40)
Nerve growth factor (NGF) is the first described neurotrophin that stimulates the growth and differentiation of nerve cells and promotes skin and peripheral tissue regeneration. Recent studies suggest that NGF influences endothelial cell proliferation and angiogenic activity. In view of these proposed regenerative effects, we evaluated the efficacy of subcutaneous administration of highly purified murine NGF in a child with severe crush syndrome of the lower left limb. NGF 10 micro g was administered subcutaneously every eight hours for seven days to the extensive ischaemic skin lesion of the calcaneal area. After treatment we observed gradual improvement of the ischaemic area; no side effects were noted. The child was discharged in good clinical condition to await a limited calcaneal escharotomy. (+info)Crush syndrome, also known as traumatic rhabdomyolysis, is a medical condition that occurs when a significant amount of muscle tissue is damaged or destroyed, releasing large amounts of intracellular contents into the circulation. This can happen due to prolonged compression of muscles, often seen in cases of entrapment in debris or heavy objects following natural disasters, accidents, or other traumatic events.
The crush syndrome is characterized by a triad of symptoms:
1. Muscle injury and breakdown (rhabdomyolysis) leading to the release of muscle contents such as potassium, myoglobin, creatine kinase, and uric acid into the bloodstream.
2. Electrolyte imbalances, particularly hyperkalemia (elevated potassium levels), which can cause cardiac arrhythmias and cardiac arrest if not promptly treated.
3. Acute kidney injury (AKI) due to myoglobinuria, where the released myoglobin from damaged muscle tissue clogs the renal tubules in the kidneys, impairing their function and potentially leading to acute renal failure.
Immediate medical intervention is crucial for managing crush syndrome, which includes aggressive fluid resuscitation, close monitoring of electrolyte levels, and supportive care for kidney function. In some cases, dialysis may be required to support the kidneys until they recover.
An earthquake is not a medical condition. It is a natural disaster that results from the sudden release of energy in the Earth's crust, causing the ground to shake and sometimes resulting in damage to structures and loss of life. The point where the earthquake originates is called the focus or hypocenter, and the epicenter is the point directly above it on the surface of the Earth.
Earthquakes can cause various medical conditions and injuries, such as:
* Cuts, bruises, and fractures from falling debris
* Head trauma and concussions
* Crush syndrome from being trapped under heavy objects
* Respiratory problems from dust inhalation
* Psychological distress, including post-traumatic stress disorder (PTSD)
If you experience an earthquake, it is important to seek medical attention if you are injured or experiencing any symptoms. Additionally, it is crucial to follow safety guidelines during and after an earthquake to minimize the risk of injury and ensure your well-being.
Traumatic shock is a type of physiological response that occurs when an individual experiences a severe physical trauma, such as severe injury, burns, or bleeding. This condition is characterized by inadequate tissue perfusion and oxygenation, which can lead to cellular damage and organ dysfunction. The primary cause of traumatic shock is a significant decrease in blood volume due to hemorrhage, which reduces the amount of oxygen and nutrients delivered to tissues and organs.
The symptoms of traumatic shock include:
1. Hypotension (low blood pressure)
2. Tachycardia (rapid heart rate)
3. Altered mental status (confusion, agitation, or lethargy)
4. Cool, clammy skin
5. Weak or absent peripheral pulses
6. Rapid, shallow breathing
7. Decreased urine output
8. Lactic acidosis (elevated levels of lactic acid in the blood)
9. Metabolic disturbances
Traumatic shock is a medical emergency that requires immediate treatment to prevent further tissue damage and organ dysfunction. Treatment typically involves fluid resuscitation, blood transfusion, and surgery to control bleeding. In some cases, medications such as vasopressors may be necessary to maintain blood pressure and perfusion to vital organs.
I apologize for any confusion, but "landslides" is not a term typically used in medical definitions. Landslides are a geological phenomenon involving the mass movement of soil or rock down a slope. They can occur due to various factors such as heavy rainfall, earthquakes, volcanic activity, or human activities that alter the stability of a slope.
If you have any questions related to health or medicine, please provide more context so I can offer an accurate and helpful response.
A disaster is a serious disruption of the functioning of a community or a society involving widespread human, material, economic or environmental losses and impacts, which exceeds the ability of the affected community or society to cope using its own resources. Disasters can be natural, such as earthquakes, hurricanes, tsunamis, and wildfires, or they can be caused by human activities, such as technological accidents, intentional acts of violence, and complex emergencies.
The medical definition of a disaster focuses on the health impacts and consequences of the event, which can include injury, illness, disability, and death, as well as psychological distress and social disruption. The response to a disaster typically involves a coordinated effort by multiple agencies and organizations, including healthcare providers, emergency responders, public health officials, and government authorities, to address the immediate needs of affected individuals and communities and to restore basic services and infrastructure.
Disasters can have long-term effects on the health and well-being of individuals and populations, including increased vulnerability to future disasters, chronic illness and disability, and mental health problems such as post-traumatic stress disorder (PTSD), depression, and anxiety. Preparedness, mitigation, response, and recovery efforts are critical components of disaster management, with the goal of reducing the risks and impacts of disasters and improving the resilience of communities and societies to withstand and recover from them.
A nerve crush injury is a type of peripheral nerve injury that occurs when there is excessive pressure or compression applied to a nerve, causing it to become damaged or dysfunctional. This can happen due to various reasons such as trauma from accidents, surgical errors, or prolonged pressure on the nerve from tight casts, clothing, or positions.
The compression disrupts the normal functioning of the nerve, leading to symptoms such as numbness, tingling, weakness, or pain in the affected area. In severe cases, a nerve crush injury can cause permanent damage to the nerve, leading to long-term disability or loss of function. Treatment for nerve crush injuries typically involves relieving the pressure on the nerve, providing supportive care, and in some cases, surgical intervention may be necessary to repair the damaged nerve.
A syndrome, in medical terms, is a set of symptoms that collectively indicate or characterize a disease, disorder, or underlying pathological process. It's essentially a collection of signs and/or symptoms that frequently occur together and can suggest a particular cause or condition, even though the exact physiological mechanisms might not be fully understood.
For example, Down syndrome is characterized by specific physical features, cognitive delays, and other developmental issues resulting from an extra copy of chromosome 21. Similarly, metabolic syndromes like diabetes mellitus type 2 involve a group of risk factors such as obesity, high blood pressure, high blood sugar, and abnormal cholesterol or triglyceride levels that collectively increase the risk of heart disease, stroke, and diabetes.
It's important to note that a syndrome is not a specific diagnosis; rather, it's a pattern of symptoms that can help guide further diagnostic evaluation and management.
