Ehlers-Danlos syndrome
Ehlers-Danlos syndrome A heritable disorder of connective tissue with easy bruising, joint hypermobility (loose joints), skin laxity, and weakness of tissues. There are a number of different types of Ehlers-Danlos syndrome (EDS) which share the foregoing features but can be categorized into at least nine different types.
RELATED TERMS--------------------------------------
Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.
Joint
Where the ends of two or more bones meet.
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).
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.
SIMILAR TERMS--------------------------------------
Ehlers Danlos Syndrome
Group of inherited disorders of connective tissue characterised by hypermobility of joints, atrophic scar formation, loss of skin elasticity and easy bruising.
Ehlers-Danlos syndrome, dermatosparaxis type
A genetic disorder characterized by extremely fragile and sagging skin caused by mutation in the ADAMTS2 gene. People with this form of Ehlers-Danlos syndrome have soft, doughy skin that is very fragile and bruises easily. The skin sags and wrinkles, and extra (redundant) folds of skin may be present as children get older. Joints are very loose, which can delay the development of motor skills such as sitting, standing, and walking. Infants with the condition are born with a soft out-pouching called a hernia around the belly-button. Other symptoms include a small chin, a blue tinge to the part of the eyeball that is usually white (the sclera), and mild overgrowth of body hair.
PREVIOUS AND NEXT TERMS--------------------------------------
Efferent nerve
A nerve that carries impulses away from the central nervous system (CNS). An efferent nerve is the opposite of an afferent nerves that carries impulses toward the CNS.
Efferent vessel
A vessel carrying blood away from the heart. An artery or arteriole.
EGD
Esophagogastroduodenoscopy.
EGF
Epidermal growth factor. A polypeptide (small protein) that is a powerful mitogen. (It stimulates cells to enter mitosis, cell division. ) EGF promotes cell growth and differentiation, is essential in embryogenesis, and is important in wound healing. It is produced by many normal cell types and is made in large amounts by some tumors. The EGF gene is on chromosome 4q25 (whereas the gene for its receptor, EGFR, is on chromosome 7). The kidney is the main source of circulating EGF. EGF is also known as urogastrone (URG).
Egg sac
The "egg sac" or ovary is one of a pair of reproductive glands in women. They are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of an almond. The ovaries have two functions: production of eggs (ova) and female hormones. Each month, during the menstrual cycle, an egg is released from one ovary. The egg travels from the ovary through a fallopian tube to the uterus.
Ehlers-Danlos syndrome
Ehlers-Danlos syndrome, dermatosparaxis type
A genetic disorder characterized by extremely fragile and sagging skin caused by mutation in the ADAMTS2 gene. People with this form of Ehlers-Danlos syndrome have soft, doughy skin that is very fragile and bruises easily. The skin sags and wrinkles, and extra (redundant) folds of skin may be present as children get older. Joints are very loose, which can delay the development of motor skills such as sitting, standing, and walking. Infants with the condition are born with a soft out-pouching called a hernia around the belly-button. Other symptoms include a small chin, a blue tinge to the part of the eyeball that is usually white (the sclera), and mild overgrowth of body hair.
Ehrlichiosis
An acute (abrupt onset) disease, clinically similar to Rocky Mountain spotted fever with high fever, headache, malaise, and muscle pain but without a rash. Laboratory features include leukopenia (low white blood cell count), thrombocytopenia (low platelet count), mild anemia, and elevation in the levels of hepatic aminotransferase enzymes. Clinical symptoms and laboratory abnormalities respond promptly to therapy with the antibiotics tetracycline or doxycycline, and the majority of patients become afebrile within 24 to 48 hours after the start of such treatment. The diagnosis of ehrlichiosis rests on the detection of ehrlichia either by direct means or by the indirect means of serologic studies. Three methods are available for detection: inspection of peripheral-blood smears, PCR testing, and tissue culture.
Eicosapentaenoic acid
One of the principal omega-3 fatty acids. Abbreviated EPA. The body has a limited ability to manufacture EPA by converting the essential fatty acid, alpha-linolenic acid (ALA) which is found in flaxseed oil, canola oil or walnuts.
Eight-day measles
An acute highly contagious viral disease with fever, runny nose, cough, red eyes, and a spreading skin rash. The eight-day measles is the ordinary measles, also known as rubeola, a potentially disastrous disease. Measles may be complicated by ear infections, pneumonia, encephalitis (that can cause convulsions, mental retardation. and even death), the sudden onset of low blood platelet levels with severe bleeding (acute thrombocytopenic purpura) or a chronic brain disease that occurs months to often years after an attack of measles (subacute sclerosing panencephalitis). During pregnancy measles may trigger miscarriages or premature delivery. Measles can be prevented through vaccination. The disease is also called the hard measles and (depending on how long you think it lasts) the seven- day measles, the nine-day measles, or the ten-day measles, and morbilli.
Eighth cranial nerve
The eighth cranial nerve is the vestibulocochlear nerve. The vestibulocochlear nerve is responsible for the sense of hearing and it is also pertinent to balance, to the body position sense. Problems with the vestibulocochlear nerve may result in deafness, tinnitus (ringing or noise in the ears), dizziness, vertigo and vomiting. The 12 cranial nerves, the vestibulocochlear nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column.
