ch 14 endocrine part 2 Flashcards
acromegaly
rare hormonal disorder in adulthood, usually caused by a GH-secreting pituitary tumor (adenoma) that promotes the soft tissue and bones of the face, hands, and feet to grow larger than normal
diuresis
increased formation and secretion of urine
glycosuria
abnormal amount of glucose in the urine
graves disease
multisystem autoimmune disorder characterized by pronounced hyperthyroidism usually associated with enlarged thyroid gland (goiter) and exophthalmos (abnormal protrusion of the eyeball)
hirsutism
excessive distribution of the body hair, especially in women
hypercalcemia
condition in which the calcium level in the blood is higher than normal
hyperkalemia
condition in which the potassium level in the blood is higher than normal
hypervolemia
abnormal increase in the volume of blood plasma (liquid part of the blood and lymphatic fluid) in the body
hyponatremia
lower than normal level of sodium in the blood
insulinoma
tumor of the islets of langerhans of the pancreas
obesity
excessive accumulation of fat that exceeds the body’s skeletal and physical standards, usually an increase of 20 percent or more above ideal body weight
morbid obesity
body mass index (BMI) of 40 or greater, which is generally 100 or more pounds over ideal body weight
panhypopituitarism
total pituitary impairment that brings about a progressive and general loss of hormone activity
pheochromocytoma
small chromaffin cell tumor, usually located in the adrenal medulla, causing elevated heart rate and blood
thyroid storm
crisis of uncontrolled hyperthyroidism caused by the release into the bloodstream of an increased amount of thyroid hormone; also called thyroid crisis or thyrotoxic crisis
virilism
masculinization or development of male secondary sex characteristics in a women
exophthalmometry
Measures the degree of forward displacement of the eyeball (exophthalmos) as seen in graves disease
parathyroidectomy
excision of one or more of the parathyroid glands, usually to control hyperparathyroidism
transsphenoidal hypophysectomy
endoscopic procedure to surgically remove a pituitary tumor through an incision in the sphenoid sinus (transsphenoidal) without disturbing brain tissue
thymectomy
excision of the thymus gland
thyroidectomy
excision of the entire thyroid gland (thyroidectomy), a part of it (subtotal thyroidectomy), or a single lobe (thyroid lobectomy)
fasting blood sugar
test that measure glucose levels in a blood sample following a fast of at least 8 hours
glucose tolerance test (GTT)
screening test in which a dose of glucose is administered and blood samples are taken afterward at regular intervals to determine how quickly glucose is cleared from the blood
insulin tolerance test (ITT)
diagnostic test in which insulin is injected into the veins to assess pituitary function, adrenal function, and to determine insulin sensitivity
thyroid function test (TFT)
test that detects an increase or decrease in thyroid function
total calcium test
test that measures calcium to detect bone and parathyroid disorders
computed tomography (CT)
imaging technique that rotates an x-ray emitter around the area to be scanned and measures the intensity of transmitted rays from different angles
magnetic resonance imaging (MRI)
noninvasive imaging technique that uses radio waves and a strong magnetic field, rather than an x-ray beam, to produce multiplayer cross-sectional images
radioactive iodine uptake (RAIU)
administration of a radioactive iodine (RAI) in pill or liquid form is used as a tracer to test how quickly the thyroid gland takes up (uptake) iodine from the blood
Thyroid scan
images of the thyroid gland are obtained after oral or intravenous administration of a small dose of radioactive iodine
antidiuretics
reduce or control excretion of urine
antithyroids
treat hyperthyroidism by impeding the formation of T3, and T4 hormone
antithyroid are administered in preparation for thyroidectomy and in thyrotoxic crisis
corticosteroids
replace hormones lost in adrenal insufficiency (addison disease)
widely used to suppress inflammation, control allergic reactions, reduce rejection in transplantation, and treat some cancers.
growth hormone replacements
increased skeletal growth in children and growth hormone deficiencies in adults
growth hormones increase spinal bone density and help manage growth failure in children
insulins
lower blood glucose levels by promoting its entrance into body cells and converting glucose to glycogen (a starch- storage form of glucose) Type 1 diabetes must always be treated with insulin. insulin can also be administered through an implanted pump
oral antidiabetics
treat type 2 diabetes mellitus by stimulating the pancreas to produce more insulin and decrease peripheral resistance to insulin
Antidiabetic drugs are not insulin and they are not used in treating type 1 diabetes mellitus
thyroid supplements
replace or supplement thyroid hormones each thyroid supplement contains T3, T4, or a combination of bath. Thyroid supplement are also used to treat some types of thyroid cancer.
