Diseases Of The Endocrine System Flashcards
What are the two different portions of the pituitary gland?
Adenohypophysis and neurohypophysis (infundibulum is the stalk that connects the gland)
What does growth hormone deficiency manifest?
Causes growth disorders in children and leads to abnormal composition in adults.
What does FSH and LH deficiency cause?
Causes menstrual disorders, infertility, and decreased sexual function and women, and the loss of secondary sexual characteristics in males.
What does TSH deficiency cause?
Causes growth retardation and children and features of hypothyroidism and both adults and children.
What does ACTH deficiency cause?
Leads to decreased production of adrenal cortical hormones.
Results from a growth hormone deficiency. Growth retardation may become evident in infancy and persists throughout childhood. Child’s growth curve may range from flat with no growth, to shallow, showing little growth.
Pituitary dwarfism
What are the symptoms and signs of pituitary dwarfism?
Slow growth for the aged five years, absent or delayed sexual development, in short stature and height for age.
How do you treat pituitary dwarfism?
Hormone replacement therapy
Is a rare condition that is usually caused by damage to the pituitary gland or the hypothalamus.
Adult growth hormone deficiency
What are the signs and symptoms of adult growth hormone deficiency?
Increased body fat, reduced exercise capacity, impaired heart function, reduced muscle mass and abnormal lipid profile
How do you treat adult growth hormone deficiency?
Hormone replacement therapy
Is a rare condition of growth hormone excess that occurs during childhood. Prior to closure of the epiphyseal growth plate, excess growth hormone stimulates excessive linear growth. Most common cause is benign tumor of the pituitary gland.
Gigantism
What are the signs and symptoms of gigantism?
Bone length increases rapidly, delayed sexual development
How do you treat gigantism?
There is no treatment
A condition that results from excess growth hormones after growth plate fusion has occurred. Most common cause is a pituitary tumor.
Acromegaly
What are the signs and symptoms of acromegaly?
Enlargement of feet, hands, space as bones grow in diameter; soft tissue growth; nose, lips, lower job protrude, and skin thicken.
How do you treat acromegaly?
There is no treatment
Decreased secretion or action of ADH results in the syndrome.
Diabetes insipidus
What are the signs and symptoms of diabetes insipidus?
Polyuria, polydipsia
How do you treat diabetes insipidus?
Administer ADH
Which gland regulates the metabolic rate?
Thyroid (with thyroxine)
May affect almost all body functions. The severity of this ranges from mild with unrecognized symptoms, to striking symptoms such as mental status changes, extreme and prolonged fatigue, weight gain, swelling or complaints of cold in the hands and feet, menstrual irregularities, muscle aches, and hair sitting.
Hypothyroidism
What causes hypothyroidism?
Primary disease of the thyroid gland, autoimmune disease, radioactive iodine, dietary iodine deficiency, lithium
How do you treat hypothyroidism?
Thyroid hormone replacement
Hypothyroidism of a newborn. Most often the result of hypoplasia, aplasia, and failure of the thyroid gland to migrate to his normal anatomical position. Caused by excessive maternal iodine intake during pregnancy.
Congenital hypothyroidism
What are the symptoms and signs of congenital hypothyroidism?
Physical and mental sluggishness, poor muscle tone, umbilical hernia, protruding abdomen, bradycardia, and growth retardation
