Focal gigantism
|
|
Focal gigantism1. The excessive growth of a specific body part such as a hand or foot, as with increased blood supply to that part. 2. The excessive growth of a combination of particular body parts, as is characteristic of a congenital malformation syndrome called the Wiedemann-Beckwith syndrome. Focal gigantism may occur before or after the bones fuse. If it occurs afterwards, it causes disfigurement, as in acromegaly. Surgery for mass reduction may sometimes improve function.
RELATED TERMS--------------------------------------
Foot
The distal portion of the leg, upon which an individual stands and walks. It consists, in man, of the tarsus, metatarsus, and phalanges and the tissues encompassing them.
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.
Congenital
Present at birth.
Malformation
Abnormal or anomalous formation or structure; deformity.
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.
Focal
Limited to one specific area.
Gigantism
Excessive growth both in height and specific body parts. Gigantism with extreme height may be associated with disorders of pituitary gland, which may oversecrete human growth hormone (somatotrophin) during childhood before the bones fuse. Excessive growth of specific body parts is also a feature of a number of disorders such as the Wiedemann-Beckwith syndrome in which there is macroglossia (an abnormally large tongue).
Acromegaly
A condition that occurs when the pituitary gland produces too much growth hormone. In adults, this can cause overgrowth of bones that occurs in smaller bones, such as those in the jaw, hands and feet. In children or teenagers, this can cause giantism.
Surgery
Treating diseases or other medical conditions by operating on a patient to remove or repair parts of the body.

Focal
Limited to one specific area.
Focal dystonia due to blepharospasm
The involuntary forcible closure of the eyelid due to spasms. The first symptoms may be uncontrollable blinking. Only one eye may be affected initially, but eventually both eyes are usually involved. The spasms may leave the eyelids completely closed causing functional blindness even though the eyes beneath the lids and vision are normal. Following torticollis (spasm of the neck muscles), blepharospasm is the next most common form of focal dystonia. For more information about dystonias, see: Dystonia.
Focal dystonia due to torticollis
Spasm of the muscles in the neck that control the position of the head, causing the head to twist and turn to one side. In addition, the head may be pulled forward or backward. Torticollis is the most common form of focal dystonia.
Focal length
Relates the distance between an image source and a lens and the distance of the lens to the image by the lenses focal length.
Focal motor seizure
A simple partial seizure with localized motor activity. There may be spasm or clonus (jerking) of one muscle or a muscle group and this may remain localized or it may subsequently spread to adjacent muscles as a Jacksonian seizure.
Focal vision
The role of vision involved in the examination and identification of objects associated with the fovea and exploratory eye movements.
Focalin
Integral part of total treatment program to stabilize ADHD/ADD.
Focalin xr
Focalin xr is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): dexmethylphenidate hydrochloride.
PREVIOUS AND NEXT TERMS--------------------------------------
FMO3
Abbreviation for the enzyme, flavin-containing monooxygenase-3.
FMR1
The gene responsible for the production of a protein called FMRP. Lack of FMRP results in the fragile X syndrome. (FMRP is an acronym composed of the first letters of Familial Mental Retardation Protein).

Folate
Folic acid, one of the B vitamins that is a key factor in the synthesis (the making) of nucleic acid (DNA and RNA). A deficiency of folic acid after birth causes a kind of anemia, namely, megaloblastic anemia in which there is a paucity of red blood cells and those that are made are unusually large and immature (so-called blast cells).
Folding motif
An independent folding unit, or particular structure, that recurs in many molecules.
Folinic acid
The active form of folic acid in the body.
Follicular cyst of the ovary
A fluid-filled sac in the ovary, the most common type of ovarian cyst. It results from the growth of a follicle. A follicle is the fluid-filled cyst that contains an egg. In some cycles, this follicle grows larger that normal and does not rupture to release the egg. Normally it resolves with simple observation over the course of days to months.
