DHF (dengue hemorrhagic fever)
|
|
DHF (dengue hemorrhagic fever)A syndrome due to the dengue virus that tends to affect children under 10, causing abdominal pain, hemorrhage (bleeding) and circulatory collapse (shock). DHF starts abruptly with high continuous fever and headache plus respiratory and intestinal symptoms with sore throat, cough, nausea, vomiting, and abdominal pain. Shock occurs after 2 to 6 days with sudden collapse, cool clammy extremities, weak thready pulse, and blueness around the mouth (circumoral cyanosis). There is bleeding with easy bruising, blood spots in the skin (petechiae), spitting up blood (hematemesis), blood in the stool (melena), bleeding gums and nosebleeds (epistaxis). Pneumonia and heart inflammation (myocarditis) may be present. The mortality is appreciable ranging from 6 to 30%. Most deaths occur in children. Infants under a year of age are especially at risk of death. DHF is also called Philippine, Thai, or Southeast Asian hemorrhagic fever and dengue shock syndrome.
RELATED TERMS--------------------------------------
Syndrome
A grouping of signs and symptoms, based on their frequent co-occurrence, that may suggest a common underlying pathogenesis, course, familial pattern, or treatment selection.
Virus
Ultramicroscopic infectious agent that replicates itself only within cells of living hosts; many are pathogenic; a piece of nucleic acid (DNA or RNA) wrapped in a thin coat of protein.
Affect
This word is used to described observable behavior that represents the expression of a subjectively experienced feeling state (emotion). Common examples of affect are sadness, fear, joy, and anger. The normal range of expressed affect varies considerably between different cultures and even within the same culture. Types of affect include: euthymic, irritable, constricted; blunted; flat; inappropriate, and labile.
Abdominal
Relating to the abdomen, the belly, that part of the body that contains all of the structures between the chest and the pelvis. The abdomen is separated anatomically from the chest by the diaphragm, the powerful muscle spanning the body cavity below the lungs. The abdomen includes a host of organs including the stomach, small intestine, colon, rectum, liver, spleen, pancreas, kidneys, appendix, gallbladder, and bladder. The word "abdomen" has a curious story behind it. It comes from the Latin "abdodere", to hide. The idea was that whatever was eaten was hidden in the abdomen.
Pain
An unpleasant sensory or emotional experience primarily associated with tissue damage, or described in terms of tissue damage, or both.
Hemorrhage
A general term for loss of blood, often profuse, brought about by injury to the blood vessels or by a deficiency of certain necessary blood elements such as platelets.
Circulatory
Having to do with the circulation, the movement of fluid in a regular or circuitous course. Although the adjective "circulatory" need not necessarily refer to the circulation of the blood, for all practical purposes today it does. A circulatory problem is taken usually to be a problem with the blood circulation, for example with heart failure.
Fever
When body temperature rises above its normal level - defined as 98.6 degrees F, though it varies by individual and time of day. A fever is the sign of an immune system at work and usually indicates an infection.
Headache
Primary - includes tension (muscular contraction), vascular (migraine), and cluster headaches not caused by other underlying medical conditions. Secondary - includes headaches that result from other medical conditions. These may also be referred to as traction headaches or inflammatory headaches.
Cough
A rapid expulsion of air from the lungs typically in order to clear the lung airways of fluids, mucus, or material.
Nausea
The feeling of wanting to throw up (vomit).
Vomiting
The release of stomach contents through the mouth.
Shock
Impaired body function due to blood loss or a disturbance in the circulatory system.
Pulse
The heartbeat as felt through the walls of an artery.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Skin
Skin is an organ of the integumentary system; which is composed of a layer of tissues that protect underlying muscles and organs. Skin is used for insulation, vitamin D production, sensation, and excretion (through sweat).
Stool
The solid wastes that pass through the rectum as bowel movements. Stools are undigested foods, bacteria, mucus, and dead cells. Also called feces.
Pneumonia
Acute inflammation or infection of the lungs.
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Inflammation
A reaction to an injury to the body - by infection, chemicals or physical agents. The symptoms can be - depending on the location of the injury- redness, swelling, heat and pain. The purpose of the inflammation is to dilute and destroy the agent causing the inflammation. To do this, the immune system starts a cascade of actions that causes active cells to gather at the affected location. It is these cells and fluids that cause the redness, swelling, heat and pain.
Mortality
Statistics on deaths within a population based on official death certificates, usually showing numbers of deaths by age, sex and cause.
Risk
In clinical trials, the probability of harm or discomfort for subjects, arising from the test product. Acceptable risk differs depending on the condition for which a product is being tested. A product for sore throat, for example, will be expected to have a low incidence of side effects. However, unpleasant side effects may be an acceptable risk when testing a promising treatment for a life-threatening illness.
Death
1. The end of life. The cessation of life. (These common definitions of death ultimately depend upon the definition of life, upon which there is no consensus.) 2. The permanent cessation of all vital bodily functions. (This definition depends upon the definition of "vital bodily functions.") See: Vital bodily functions. 3. The common law standard for determining death is the cessation of all vital functions, traditionally demonstrated by "an absence of spontaneous respiratory and cardiac functions." 4. The uniform determination of death.

Dextroposition
Move to the right.
Dextroposition of the heart
The heart is displaced to the right (from its usual location in the left chest). There is no anatomic alteration in the heart itself, just in its location. Dextroposition occurs when the contents of the left side of the chest shove the heart to the right or when the contents of the right chest are reduced (for example, by collapse of the right lung) and the heart moves toward the sparsely occupied space on the right.
DFSP
Dermatofibrosarcoma protuberans.
DHA
Docosahexaenoic acid, an essential fatty acid, thought to be important to the development of infants, particularly as regards their eyes and brain. DHA is present in breast milk and has been added to some infant formulas. Postnatal DHA may improve vision and some cognitive functions in infants and toddlers. DHA is an omega-3, polyunsaturated, 22-carbon fatty acid. It is present in abundance in certain fish (such as tuna and bluefish) and marine animal oils.
DHEA
Dehydroepiandrosterone.
DHF (dengue hemorrhagic fever)
DHRD
Doyne honeycomb retinal dystrophy, an eye disease also known as malattia leventinese.
DHT
Dihydrotestosterone.
Di Bella cancer therapy
An alternative medicine cancer treatment based on a drug cocktail containing a low dose of cyclophosphamide plus other drugs and vitamins and given to more than 10,000 patients, nearly 100% of whom were allegedly cured.
Diabesity
Diabetes caused by overweight or obesity
Diabetes and fiber
Soluble fibers (oat bran, apples, citrus, pears, peas/beans, psyllium, etc.) slow down the digestion of carbohydrates (sugars), which results in better glucose metabolism. Some patients with the adult-onset diabetes may actually be successfully treated with a high-fiber diet alone, and those on insulin, can often reduce their insulin requirements by adhering to a high-fiber diet.
