Screening for Endocrine and Metabolic Disease Flashcards
what makes up the endocrine system?
ductless glands that produce hormones
what is the function of the endocrine system?
- regulates:
- metabolism
- water/salt balance
- BP
- stress response
- sexual reproduction
- complex and integral interactions with the nervous system
- feedback mechanisms exist to keep hormones at normal levels
list the organs of the endocrine system
- hypothalamus
- pineal gland
- pituitary gland
- thyroid gland
- parathyroid gland
- thymus
- adrenal gland
- pancreas
- tests/ovaries
how are disorders of the endocrine system classified?
- primary → dysfunction of the gland itself
- secondary → dysfunction of an outside stimulus to the gland
results in either excessive or insufficient secretion of hormones
list S/S of endocrine or metabolic disease
- muscle weakness, myalgia, and fatigue → early manifestation of endocrine/metabolic disease
- bilateral carpal tunnel syndrome
- can be due to a thickening of transverse carpal ligament
- periarthritis and calcific tendonitis
- most often occurs in shoulders
- spondyloarthropathy and osteoarthritis
- hand stiffness/pain
- flexor tenosynovitis
T/F: dysfunction in the form of muscle weakness, myalgia and fatigue are always restored after treatment of underlying condition
FALSE
List what is included in the ROS for endocrine disorders
- hair and nail changes
- change in appetite, unexplained weight change
- fruity breath odor
- temp intolerance, hot flashes, diaphoresis
- heart palpitations, tachycardia
- HA
- low urine output, absence of perspiration
- cramps
- edema, polyuria, polydipsia, polyphagia
- unexplained weakness, fatigue, paresthesia
- carpal/tarsal tunnel syndrome
- periarthritis, adhesive capsulitis
- joint or muscle pain (arthralgia, myalgia), trigger points
- prolonged DTRs
- sleep disturbance
list endocrine pathologies associated with each organ
- Pituitary gland → Acromegaly
- Adrenal glands → Addison’s disease and Cushing’s syndrome
- Thyroid gland → Hyperthyroidism/Grave’s disease, and Hypothyroidism
- Pancreas → diabetes mellitus
what is Acromegaly?
hypersecretion of growth hormone (GH) resulting in abnormal enlargement of the extremities of the skeleton
- most commonly affects enlargement of face, jaw, hands, feet
- occurs in adults usually due to a pituitary gland tumor
Clinical S/S of Acromegaly
- Bony enlargement (face, jaw, hands, feet)
- Carpal tunnel
- hand pain and stiffness
- myopathy and poor exercise tolerance
- degenerative arthropathy (large joints)
- amenorrhea
- DM
- diaphoresis
- HTN
what is the cause of Addison’s disease?
adrenal insufficiency → hyposecretion of adrenal gland
clinical S/S of Addison’s disease
- dark pigmentation of the skin, especially mouth and scar
- progressive fatigue (improves with rest)
- hyperkalemia → results in generalized weakness and muscle flaccidity
- arthralgia, myalgias (secondary only)
- tendon calcification
- hypotension
- GI disturbances
- anorexia and weight loss
- N/V
- hypoglycemia
what is Cushing’s syndrome?
hypersecretion of cortisol by adrenal cortex
what are the effects of cortisol on connective tissue?
- poor wound healing
- generalized muscle weakness and wasting
- osteoporosis
how does cortisol influence inflammation?
cortisol suppresses the inflammatory response of the body; therefore early signs of infection may not be present
any unexplained fever w/o other symptoms should warrant MD referral
Clinical S/S of Cushing’s syndrome
- Moonface appearance
- Buffalo hump
- protuberant abdomen with accumulation of fatty tissue and stretch marks
- muscle wasting and weakness, thin extremities
- decreased bone density, kyphosis, back pain
- HTN
- easy bruising and slow wound healing
- psychiatric and/or emotional disturbance
- impaired reproduction function, masculinizing effects
- DM
what is hyperthyroidism (aka Grave’s disease)?
disorder in which the thyroid secretes excessive amounts of thyroid hormone
results in generalized elevation in body metabolism effecting every system in the body
MSK implications of hyperthyroidism (Grave’s disease)
- periarthritis → most commonly in the shoulder and can progress to adhesive capsulitis
- acute calcific tendonitis of the wrists
- proximal muscle weakness and myopathy (pelvic girdle/thigh muscles)
Clinical S/S of hyperthyroidism (Grave’s disease)
- Exophthalmos
- enlarged thyroid
- tachycardia
- weight loss
- diarrhea
- warm skin, sweaty palms
- hyperreflexia
what is a thyroid storm?
rare, life threatening complication of hyperthyroidism that can present when the disease is untreated or the disease is incorrectly treated
what are some precipitating factors of a thyroid storm?
trauma, infection, surgery
Symptoms of a thyroid storm
- severe tachycardia w/HF
- shock
- hyperthermia (up to 105.3 degrees F)
- restlessness
- agitation
- abdominal pain
- N/V
- coma
what is hypothyroidism?
the under production of thyroid hormone creating a general depression of body metabolism
women are 10x more likely than men to have hypothyroidism
MSK implications of hypothyroidism
- Carpal tunnel syndrome
- flexor tenosynovitis often accompanies
- usually presents bilaterally
- Proximal muscle weakness
- sometimes accompanied by aches, cramps, stiffness
- development of persistent myofascial trigger points
- apparent association between hypothyroidism and fibromyalgia
Clinical S/S of hypothyroidism
- excessive fatigue and drowsiness
- dry skin, ichthyosis
- thin and brittle hair and nails
- hoarseness and thick, slurred speech
- weight gain
- HA
- cold intolerance
- edema of the extremities
what is diabetes?
deficient or defective insulin action in the body, characterized by hyperglycemia
Type I → little or no insulin produced by pancreas
Type II → defective insulin and/or impaired cell receptor binding of insulin
how is Diabetes Diagnosed?
- two different days of fasting blood glucose levels at >126
- values >100 are considered “pre-diabetic”
