Summary
Heat stroke cases in service members increased in 2011 compared to 2010, with highest incidence in young males in combat roles. Other heat injuries also rose, affecting females and enlisted personnel more.
Area of Science:
- Environmental Medicine
- Occupational Health
- Military Health
Background:
- Heat-related illnesses pose a significant risk to military personnel.
- Understanding trends in heat stroke and other heat injuries is crucial for prevention.
Purpose of the Study:
- To analyze the incidence and demographic trends of heat stroke and other heat injuries among service members from 2007 to 2011.
- To identify high-risk groups for these conditions within the military population.
Main Methods:
- Retrospective analysis of medical treatment data for service members.
- Calculation of incidence rates based on demographic and occupational factors.
Main Results:
- Heat stroke cases in 2011 (n=362) increased from 2010 but were lower than 2007-2009. Incidence was highest in males, combat occupations, Marines/Army, and those under 20.
- Cases of "other heat injuries" (n=2,652) were highest in 2011 compared to the prior four years, though hospitalizations decreased.
- Unlike heat stroke, "other heat injuries" had higher incidence rates in females and enlisted members compared to males and officers, respectively.
Conclusions:
- Heat stroke incidence is concentrated in specific demographics and occupations within the military.
- "Other heat injuries" show a different demographic risk profile, with higher rates in females and enlisted personnel.
- Targeted prevention strategies are needed for different types of heat injuries and at-risk military subgroups.

01:22Burn Injuries
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:22Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

02:45Responses to Heat and Cold Stress
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
01:21Cellular Injury II: Classification
Cellular injury is any process that disrupts a cell’s ability to maintain homeostasis, leading to structural or functional changes. It is broadly classified based on etiology (cause) and mechanism of damage.Classification by EtiologyCellular injury may result from several causes. Hypoxic injury happens due to reduced oxygen delivery, most commonly from inadequate blood supply, such as arterial obstruction; for example, coronary artery thrombosis can cause myocardial infarction. Chemical injury...
01:25Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
