| true vertebra | Any one of the cervical, thoracic, or lumbar vertebrae. Synonym: vertebra vera. (05 Mar 2000) |
| true vocal cord | One of Ferrein's cords; the sharp edge of a fold of mucous membrane overlying the vocal ligament and stretching along either wall of the larynx from the angle between the laminae of the thyroid cartilage to the vocal process of the arytenoid cartilage; the vocal folds are the agents concerned in voice production.

| adaptive hypertrophy | Thickening of the walls of a hollow organ, like the urinary bladder, when there is obstruction to outflow. (05 Mar 2000) |
| benign prostatic hypertrophy | <urology> A benign enlargement of the prostate gland begins normally after age 50 years probably secondary to the effects of male hormones. If significant enlargement occurs, it may pinch off te urethra making urination difficult or impossible. See: urinary retention. (06 Aug 1998) |
| giant hypertrophy of gastric mucosa | Gastric mucosal hyperplasia, either mucoid or glandular; the latter type may be associated with the Zollinger-Ellison syndrome. Synonym: giant hypertrophy of gastric mucosa, hypertrophic gastritis, Menetrier's syndrome. (05 Mar 2000) |
| gingival hypertrophy | <dentistry> The abnormal enlargement of the gingiva surrounding the teeth caused by poor oral hygiene. (08 Jan 1998) |
| vicarious hypertrophy | Hypertrophy of an organ following failure of another organ because of a functional relationship between them; e.g., enlargement of the pituitary gland, after destruction of the thyroid. (05 Mar 2000) |
| right ventricular hypertrophy | <radiology> Pulmonary valve stenosis, pulmonary hypertension, tetralogy of Fallot, VSD (12 Dec 1998) |
| physiologic hypertrophy | Temporary increase in size of an organ or part to provide for a natural increase of function, such as the kind that occurs in the walls of the uterus and in the mammae during pregnancy. Synonym: functional hypertrophy. (05 Mar 2000) |
| compensatory hypertrophy | Increase in size of an organ or part of an organ or tissue, when called upon to do additional work or perform the work of destroyed tissue or of a paired organ. (05 Mar 2000) |
| compensatory hypertrophy of the heart | Thickening of the walls of the heart in response to vascular, valvular, other heart disease, or athletic conditioning. (05 Mar 2000) |
| complementary hypertrophy | Increase in size or expansion of part of an organ or tissue to fill the space left by the destruction of another portion of the same organ or tissue. (05 Mar 2000) |
| concentric hypertrophy | Thickening of the walls of the heart or any cavity with apparent diminution of the capacity of the cavity. (05 Mar 2000) |
| haemangiectatic hypertrophy | <syndrome> A congenital malformation syndrome characterised by the triad of asymmetric limb hypertrophy, haemangiomata, and nevi. Asymmetric limb hypertrophy is enlargement of one limb and not the corresponding limb on the other side, the enlarged limb being 3 times more likely to be a leg than an arm in ktw; and the limb enlargement is of bone as well as soft tissue. The haemangiomas, abnormal nests of blood vessels that proliferate inappropriately and excessively, cover a remarkable range from small innocuous capillary haemangiomas ( strawberry marks ) to huge cavernous haemangiomas. The nevi are pigmented moles on the skin; in ktw there are often also dark linear streaks on the skin, streaks due to too much pigment. There can be other abnormalities but the triad is the consistent clinical centrepiece of the disease. most persons with ktw have an enlarged leg and do relatively well without treatment or, for example, with only compression from an elastic stocking. Skin ulcers and other skin problems can occur over the swollen leg. Usually, the treatment is conservative. Surgery is almost never needed. The only possible exceptions are the very rare situations in which the leg reaches gigantic proportions or secondary clotting difficulties arise (due to trapping and destruction of blood platelets in a huge haemangioma). Then, amputation may become necessary. The cause of ktw syndrome is unknown. (12 Dec 1998) |
