insufficiency

 [in″sŭ-fish´en-se]
inability to perform properly an allotted function; called also incompetence.
adrenal insufficiency abnormally diminished activity of the adrenal gland; called also hypoadrenalism.
adrenocortical insufficiency abnormally diminished secretion of corticosteroids by the adrenal cortex; see also addison's disease. Called also hypoadrenocorticism and hypocorticism.
aortic insufficiency inadequate closure of the aortic valve, permitting aortic regurgitation.
coronary insufficiency decreased supply of blood to the myocardium resulting from constriction or obstruction of the coronary arteries, but not accompanied by necrosis of the myocardial cells. Called also myocardial ischemia.
ileocecal insufficiency inability of the ileocecal valve to prevent backflow of contents from the cecum into the ileum.
mitral insufficiency inadequate closure of the mitral valve, permitting mitral regurgitation.
placental insufficiency dysfunction of the placenta, with reduction in the area of exchange of nutrients; it often leads to fetal growth retardation.
pulmonary valve insufficiency inadequate closure of the pulmonary valve, permitting pulmonic regurgitation.
respiratory insufficiency see respiratory insufficiency.
thyroid insufficiency hypothyroidism.
tricuspid insufficiency incomplete closure of the tricuspid valve, resulting in tricuspid regurgitation.
valvular insufficiency failure of a cardiac valve to close perfectly, causing valvular regurgitation; see also aortic, mitral, pulmonary, and tricuspid insufficiency.
velopharyngeal insufficiency inadequate velopharyngeal closure, due to a condition such as cleft palate or muscular dysfunction, resulting in defective speech.
venous insufficiency inadequacy of the venous valves and impairment of venous return from the lower limbs (venous stasis), often with edema and sometimes with stasis ulcers at the ankle.

The statement includes guidelines on identifying and treating women with thyroid insufficiency before and during pregnancy, as well as a research agenda for determining the risks and benefits of treating maternal subclinical hypothyroidism.
Goiter becomes apparent during infancy or early childhood, but it is usually not accompanied by signs of thyroid insufficiency. The laboratory method for assessing iodide organification is the perchlorate discharge test, which produces a marked decline in the radioiodine content of the thyroid gland (to [less than or equal to] 10% of baseline value).
Bone age films of the ossification centers at the knee give some indication as to the duration and severity of the thyroid insufficiency. A biochemical assay may provide this information in the future, as serum [alpha]-fetoprotein levels in hypothyroid infants have been found to be increased in inverse proportion to the skeletal maturation index.[1] Duration and severity of the thyroid insufficiency at birth have been shown to correlate closely with ultimate prognosis for intellectual development.
