Study Notes
Adrenal Glands
- Generally located atop both kidneys, adrenal glands consist of the medulla (center) and cortex (outer portion).
- Function includes hormone production necessary for heart rate, blood pressure, metabolism, stress response, and blood sugar regulation.
- Medulla secretes epinephrine (adrenaline) and norepinephrine; the cortex produces aldosterone, cortisol, and androgens.
Adrenal Insufficiency
- Two main types: Primary (Addison’s disease) and Secondary; both are chronic conditions.
- Primary adrenal insufficiency often results from autoimmune issues, tuberculosis, or AIDS. Symptoms emerge after 90% of adrenal cortex damage occurs; predominantly affects women aged 40+.
- Secondary adrenal insufficiency arises from pituitary gland dysfunction, leading to inadequate ACTH production, thus decreasing cortisol levels. It is more common and typically affects individuals over 60, with a higher prevalence in women.
Signs and Symptoms
- Common signs of both Primary and Secondary adrenal insufficiency include flu-like symptoms, nausea, fatigue, weight loss, and hyperpigmentation (specific to Addison’s).
Treatment for Adrenal Insufficiency
- Hormone replacement therapy is crucial, mainly utilizing hydrocortisone to stabilize hormone levels.
Adrenal Crisis
- A severe and life-threatening condition reflecting a critical lack of cortisol; can be triggered by unrecognized adrenal insufficiency or stressful situations requiring higher cortisol levels.
- Typical signs include hypotension, dehydration, tachycardia, shock, and potential cardiac arrest.
Emergency Management for Adrenal Crisis
- Position the patient supine with elevated feet if hypotensive; if not, ensure comfort.
- Symptoms to monitor: lightheadedness, fatigue, nausea, headaches, heart palpitations, confusion, and blurry vision.
- Definitive care involves calling EMS, monitoring vital signs, administering supplemental oxygen if necessary, and administering glucocorticosteroids if available and the patient has a history of adrenal insufficiency.
Prevention of Adrenal Crisis
- Rare in dental settings; risk factors include premature cessation of corticosteroid treatments and stressful dental appointments.
- Most patients on corticosteroids do not require additional doses unless major surgery or severe anxiety is involved.
Thyroid Gland Overview
- The thyroid gland is a butterfly-shaped endocrine organ located anterior to the trachea, responsible for producing hormones that regulate metabolic and growth rates.
Goiter
- Goiter signifies an enlarged thyroid that could derive from hyperthyroidism, hypothyroidism, or normal hormone production. It is often associated with inflammation and may not be present in all instances.
Hyperthyroidism vs. Hypothyroidism
- Hyperthyroidism is characterized by increased metabolic processes, while hypothyroidism results in decreased activity.
- Symptoms vary significantly and require differentiation for effective patient management in dental settings.
