Antibiotic: A drug used to treat infections caused by bacteria and other microorganisms. Originally, an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another. Synthetic antibiotics, usually chemically related to natural antibiotics, have since been produced that accomplish comparable tasks. See the entire definition of Antibiotic
Anxiety: A feeling of apprehension and fear characterized by physical symptoms such as palpitations, sweating, and feelings of stress. Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults. These disorders fill people's lives with overwhelming anxiety and fear. Unlike the relatively mild, brief anxiety caused by a stressful event such as a business presentation or a first date, anxiety disorders are chronic, relentless, and can grow progressively worse if not treated. See the entire definition of Anxiety
Boil: A skin abscess, a collection of pus localized deep in the skin. A boil usually starts as a reddened, tender area and in time becomes firm and hard. Eventually, the center of the abscess softens and becomes filled with white blood cells that the body sends to fight the infection. This collection of white cells is the pus. See the entire definition of Boil
Carbon dioxide: A gas which is the byproduct of cellular metabolism and which collects in the tissues, is cleared from the tissues by the blood within the veins, is carried by the hemoglobin in the red blood cells, and removed from the body via the lungs in the exhaled air. Abbreviated CO2.
Carbon monoxide poisoning: Poisoning with carbon monoxide, a tasteless odorless gas that is a byproduct of combustion. Carbon monoxide acts as a poison by competing with oxygen for binding sites on hemoglobin, the molecule in red blood cells that carries oxygen from the lungs to the more remote tissues of the body and returns carbon dioxide from the tissues to the lungs. On inhalation, carbon monoxide binds to hemoglobin with a binding affinity 200--270 times greater than that of oxygen. See the entire definition of Carbon monoxide poisoning
CDC: The Centers for Disease Control and Prevention, the US agency charged with tracking and investigating public health trends. The stated mission of the CDC is "To promote health and quality of life by preventing and controlling disease, injury, and disability." The CDC is a part of the U.S. Public Health Services (PHS) under the Department of Health and Human Services (HHS). See the entire definition of CDC
Cell: The basic structural and functional unit in people and all living things. Each cell is a small container of chemicals and water wrapped in a membrane. See the entire definition of Cell
Cuts: Severed skin. Washing a cut or scrape with soap and water and keeping it clean and dry is all that is required to care for most wounds. Putting alcohol hydrogen peroxide, and iodine into a wound can delay healing and should be avoided. Seek medical care early if you think that you might need stitches. Any delay can increase the rate of wound infection. Any puncture wound through tennis shoes has a high risk of infection and should be seen by your healthcare professional. Any redness, swelling, increased pain, or pus draining from the wound may indicate an infection that requires professional care.
Depression: An illness that involves the body, mood, and thoughts, that affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. A depressive disorder is not the same as a passing blue mood. It is not a sign of personal weakness or a condition that can be wished away. People with a depressive disease cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression. See the entire definition of Depression
Dizziness: Painless head discomfort with many possible causes including disturbances of vision, the brain, balance (vestibular) system of the inner ear, and gastrointestinal system. Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions ranging from lightheadedness, unsteadiness to vertigo. See the entire definition of Dizziness
Grief: The normal process of reacting to a loss. The loss may be physical (such as a death), social (such as divorce), or occupational (such as a job). Emotional reactions of grief can include anger, guilt, anxiety, sadness, and despair. Physical reactions of grief can include sleeping problems, changes in appetite, physical problems, or illness. See the entire definition of Grief
Heat-related illness: A person with symptoms including headache, nausea, and fatigue after exposure to heat probably has some measure of a heat-related illness. It is important to recognize the difference between the very serious condition known as heat stroke and other heat-related illnesses. Persons experiencing any of these symptoms should consult a doctor. See the entire definition of Heat-related illness
Hurricane: A regionally specific name for a strong tropical cyclone. The term hurricane applies in the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, or the South Pacific Ocean east of 160E. See the entire definition of Hurricane
Hyperactivity: A higher than normal level of activity. An organ can be described as hyperactive if it is more active than usual. Behavior can also be hyperactive. See the entire definition of Hyperactivity
Indicate: In medicine, to make a treatment or procedure advisable because of a particular condition or circumstance. For example, certain medications are indicated for the treatment of hypertension during pregnancy while others are contraindicated.
Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person. See the entire definition of Infection
Injury: Harm or hurt. The term "injury" may be applied in medicine to damage inflicted upon oneself as in a hamstring injury or by an external agent on as in a cold injury. The injury may be accidental or deliberate, as with a needlestick injury. The term "injury" may be synonymous (depending on the context) with a wound or with trauma.
Lethargy:1. Abnormal drowsiness, stupor. 2. A state of indifference. From the Greek lethargia, drowsiness.
Nausea:Nausea, is the urge to vomit. It can be brought by many causes including, systemic illnesses, such as influenza, medications, pain, and inner ear disease. When nausea and/or vomiting are persistent, or when they are accompanied by other severe symptoms such as abdominal pain, jaundice, fever, or bleeding, a physician should be consulted.
NIOSH: The National Institute for Occupational Safety and Health, a US Federal agency responsible for conducting research and making recommendations for the prevention of work-related disease and injury. See the entire definition of NIOSH
Ointment: A medication preparation that is applied topically (onto the skin). An ointment has an oil base whereas a cream is water-soluble. (The word ointment comes from the Latin ungere meaning anoint with oil).
Poisoning: Taking a substance that is injurious to health or can cause death. Poisoning is still a major hazard to children, despite child-resistant (and sometimes adult-resistant) packaging and dose-limits per container. See the entire definition of Poisoning
Prescription: A physician's order for the preparation and administration of a drug or device for a patient. A prescription has several parts. They include the superscription or heading with the symbol "R" or "Rx", which stands for the word recipe (meaning, in Latin, to take); the inscription, which contains the names and quantities of the ingredients; the subscription or directions for compounding the drug; and the signature which is often preceded by the sign "s" standing for signa (Latin for mark), giving the directions to be marked on the container.
Probability: The likelihood that something will happen. For example, a probability of less than .05 indicates that the probability of something occurring by chance alone is less than 5 in 100, or 5 percent. This level of probability is usually taken as the level of biologic significance, so a higher incidence may be considered meaningful. The abbreviation for probability is P.
Ringing in the ears: Medically called tinnitus, this can arise in any of "the four sections of the ear" -- the outer ear, the middle ear, the inner ear, and the brain -- and can be due to many causes including ear infections, fluid in the ears, Meniere syndrome (the combination of tinnitus and deafness), some medications such as aspirin and other nonsteroidal antiinflammatory drugs (NSAIDs), aging, and ear trauma (such as from the noise of planes, firearms, or loud music). In rare situations, tinnitus may also be due to an aneurysm or an acoustic neuroma (a benign tumor on the acoustic nerve). Woodwind players are more likely to experience tinnitus than other orchestral players, probably because they usually sit just in front of the brass. If tinnitus persists or its cause is unknown, a hearing test (audiogram) should be done. Measures can be taken to lessen the intensity of tinnitus or to mask it.
Saffir-Simpson hurricane scale: A 1-5 rating based on the hurricane's present intensity. This scale is used to give an estimate of the potential property damage and flooding expected along the coast from a hurricane landfall. Wind speed is the determining factor in the scale, as storm surge values are highly dependent on the slope of the continental shelf in the landfall region. Note that all winds are using the U.S. 1-minute average. See the entire definition of Saffir-Simpson hurricane scale
Shank:1. In anatomy, the tibia, the larger bone in the lower leg. The term is rarely used in this sense today. 2. In a culinary sense, the foreleg of a four-legged animal as, for example, a lamb shank. The shank is flavorful but tough (due to connective tissue) and therefore needs long slow cooking.
Sodium: The major positive ion (cation) in fluid outside of cells. The chemical notation for sodium is Na+. When combined with chloride, the resulting substance is table salt. See the entire definition of Sodium
Storm surge: The onshore rush of sea or lake water caused primarily by the high winds that are associated with a landfalling hurricane, typhoon, or tropical cyclone and secondarily by the low pressure of the storm. The term tidal surge is often mis-used to describe storm surge, but a storm surge is independent of the usual tidal ebb and flo.
Strain: 1. An injury to a tendon or muscle resulting from overuse or trauma. 2. A hereditary tendency that originated from a common ancestor. 3. To exert maximum effort. 4. To filter.
Stress: Forces from the outside world impinging on the individual. Stress is a normal part of life that can help us learn and grow. Conversely, stress can cause us significant problems. See the entire definition of Stress
Taste: Taste belongs to our chemical sensing system, or the chemosenses. The complicated process of tasting begins when molecules released by the substances stimulate special cells in the mouth or throat. These special sensory cells transmit messages through nerves to the brain where specific tastes are identified. See the entire definition of Taste
Teaspoon: An old-fashioned but convenient household measure. A teaspoon holds about 5 cc of liquid.
Tetanus: An often fatal infectious disease caused by the bacteria Clostridium tetani (C. tetani) which usually enters the body through a puncture, cut, or open wound. Tetanus is characterized by profoundly painful spasms of muscles, including "locking" of the jaw so that the mouth cannot open (lockjaw). C. tetani releases a toxin that affects the motor nerves, (the nerves which stimulate the muscles). See the entire definition of Tetanus
Thermometer: A device used to measure the temperature of gaseous, liquid or solid matter or of a chemical reaction such as fire. Temperature measurement is important to a wide range of activities, including industry, scientific research, and health care. In health care, thermometers are used to measure the temperature of the human body. They include the following types: See the entire definition of Thermometer
Tinnitus: "Ringing in the ears" or another noise that seems to originate in the ears or head. See the entire definition of Tinnitus
Trauma: Any injury, whether physically or emotionally inflicted. "Trauma" has both a medical and a psychiatric definition. Medically, "trauma" refers to a serious or critical bodily injury, wound, or shock. This definition is often associated with trauma medicine practiced in emergency rooms and represents a popular view of the term. In psychiatry, "trauma" has assumed a different meaning and refers to an experience that is emotionally painful, distressful, or shocking, which often results in lasting mental and physical effects. See the entire definition of Trauma
Anxiety is a feeling of apprehension and fear characterized by physical symptoms. Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults.
Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. The best way to treat dehydration is to prevent it from occurring.
Tinnitus is a ringing or swishing that seems to originate in the ear or head. Most of the time it is not a serious problem (it is however, a nuisance to those that suffer from the condition). Causes of tinnitus include loud noise exposure (firearms, loud music), medications, and other diseases (Meniere's disease). Treatment options are limited for tinnitus. Tinnitus can be prevented by wearing hearing protection when exposed to loud noises.
Nausea is an uneasiness of the stomach that often precedes vomiting. Nausea and vomiting are not diseases, but they are symptoms of many conditions. The causes of vomiting differ according to age, and treatment depends upon the cause of nausea and vomiting.
Stress occurs when forces from the outside world impinge on the individual. Stress is a normal part of life. However, over-stress, can be harmful. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions.
Heat rash is a skin irritation caused by excessive sweating. It can occur at any age and it appears as a rash that itches or feels prickly, and looks like a red cluster of pimples or small blisters. Pictures of heat rash are included.
Depression is an illness that involves the body, mood, and thoughts and affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. The principal types of depression are major depression, dysthymia, and bipolar disease (also called manic-depressive disease).
Suicide is the process of intentionally ending one's own life. Approximately 1 million people worldwide commit suicide each year, and 10 million to 20 million attempt suicide annually.
Heat stroke (heatstroke or sun stroke) is a form of hyperthermia. Heat stroke is a true medical emergency that can be fatal if not promptly and properly treated. Symptoms of heat stroke include: high body temperature, absence of sweating, with hot red or flushed dry skin, rapid pulse, difficulty breathing, strange behavior, hallucinations, confusion, agitation, disorientation, seizure, and coma. A victim of heat stroke must receive immediate treatment to avoid permanent organ damage.
Burns are categorized by severity as first, second, or third degree. First degree burns are similar to a painful sunburn. The damage is more severe with second degree burns, leading to blistering and more intense pain. The skin turns white and loses sensation with third degree burns. Burn treatment depends upon the location, total burn area, and intensity of the burn.
Grief is the feeling one experiences after a loss (of a friendship, death of loved one, job). Complicated grief refers to grief that lasts for more than a year. Mourning describes the customs and rituals that help a bereaved individual make sense of their loss.
Tetanus is an often-fatal disease caused by nerve toxins produced by the common bacteria Clostridium tetani. In a seven-day period after infection, a person experiences muscle spasms, restlessness, headache, irritability, then lockjaw, and the lungs stop functioning. Tetanus is treatable with antibiotics and drainage. Sedation is often give to stop muscle spasms.
Cuts, scrapes, and puncture wounds are common, and most people will experience one of these in their lifetime. Evaluating the injury, and thoroughly cleaning the injury is important. Some injuries should be evaluated by a doctor, and a tetanus shot may be necessary. Treatment will depend upon the severity of the injury.
Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement fluids. Warning signs of heat exhaustion include heavy sweating, paleness, muscle cramps, tiredness, weakness, dizziness, headache, nausea or vomiting, and fainting.
Stress may be considered as any physical, chemical, or emotional factor that causes bodily or mental unrest and that may be a factor in disease causation. An important goal for those under stress is the management of stress in our lives. Elimination of stress is unrealistic, since stress is a part of normal life. We can however, learn to manage stress through techniques such as exercise, relaxation, meditation, time management, and support systems so that we have control over our stress and its effects on our physical and mental health.
Hyperthermia is the overheating of the body. Heat-related illnesses like heat stroke, heat exhaustion, heat cramps, heat rash, and sunburn are all hyperthermia conditions. Treatment of these conditions depends upon the condition, environment, and circumstances. Heat stroke is a medical emergency, and may result in death if not treated promptly. Heat exhaustion may lead to heat stroke if not treated properly.
Drowning is a common cause of death and disability worldwide. In the US, it is the third most common cause of accidental death. Brain damage, pneumonia, ARDS, hypothermia, and spine fractures are complications of drowning. At times, there are discussions of wet vs. dry, or salt vs. fresh water drownings. Children and young adults are at most risk for drowning accidents. Medical emergencies in the water may lead to drowning (such as seizures, hypoglycemia, sudden cardiac death, or heart attack). Treatment of a drowning victim depends up on the severity of the injury. Prevention is the key to prevent drowning.
Noise-induced hearing loss may be an acoustic trauma (temporary hearing loss), or permanent due to an acute acoustic trauma. Experts agree that continual exposure to more then 85 dBs (decibels) is dangerous to the ears. Ear plugs and ear muffs can help prevent noise-induced hearing loss as well as decreasing exposure to loud noises.
Heat cramps usually affect people who sweat a lot during strenuous activity or work in a hot humid environment. Symptoms of heat cramps are muscle pains or spasms, usually in the abdomen, arms or legs that occur in association with strenuous activity. Heat cramps is part of a group of heat-related illnesses.
First aid is a complicated subject and it is situation-specific. First aid is the help and medical assistance that someone gives, not only to an injured person, but to a person who is sick. Preparedness is a key element of first aid, like having basic medical emergency kits in your home, car, boat, or RV. Cuts, puncture wounds, sprains, strains, nosebleeds are one type of injury that may require first aid; heart attacks, strokes, seizures, and heat stroke are examples of more critical first aid emergencies.
Taking care of a disease such as diabetes is a life-long process. Learn how to care for yourself or loved one with diabetes in situations such as illness, work, school, travel, or a natural disaster.
Generalized anxiety disorder (or GAD) is characterized
by excessive, exaggerated
anxiety and worry about everyday life events with no obvious reasons for
worry. People with
symptoms of generalized anxiety disorder tend to always expect disaster and
can't stop worrying about health, money, family, work, or school. In people
with GAD, the worry often is unrealistic or out of proportion for the
situation. Daily life becomes a constant state of worry, fear, and dread.
Eventually, the anxiety so dominates the person's thinking that it interferes
with daily functioning, including work, school, social activities, and
relationships.
What Are the Symptoms of GAD?
GAD affects the way a person thinks, but the anxiety can lead to physical
symptoms, as well. Symptoms of GAD can include:
