Study Notes
Hyperparathyroidism
- Results from excessive parathyroid hormone production.
- Causes bone decalcification and formation of calcium-containing kidney stones.
- Symptoms include pain, fatigue, muscle weakness, nausea, vomiting, constipation, hypertension, cardiac arrhythmias, and anorexia.
- Treatment involves the surgical removal of one or more parathyroid glands, usually performed minimally invasively on an outpatient basis.
- Increased daily fluid intake (more than 2 liters) is crucial to prevent kidney stone formation.
- Weight-bearing activities like walking are recommended to reduce calcium release from bones.
- Bedrest can exacerbate calcium excretion, increasing kidney stone risk.
- Encourage a normal calcium diet and manage constipation with prune juice, activity, and stool softeners.
Hypoparathyroidism
- Often caused by removal or damage to parathyroid glands during thyroid surgery.
- Other causes include autoimmune disorders and vitamin D deficiency.
- Leads to hyperphosphatemia (high blood phosphate) and hypocalcemia (low calcium), with hypocalcemia being the primary symptom.
- Symptoms include muscle tremors, spasms, numbness, tingling, and positive Trousseau's and Chvostek's signs.
- Treatment aims to raise serum calcium levels to 9-10 mg/dL, with options including calcium, magnesium, herbal calciferol, and calcitriol.
Pituitary Disorders
Acromegaly
- A rare condition characterized by excess growth hormone (GH) in adults without height increase.
- Diagnosed using labs, X-rays, and CT scans.
- Physical signs include enlarged facial features, hands, and feet, and deepening voice.
- Symptoms involve headaches, sweating, hypertension, and increased risk of diabetes and heart issues if untreated.
- Treatment options include surgery, medications to inhibit GH release, and radiation therapy.
- Notable medications include octreotide, lanreotide, and pegvisomant.
Diabetes Insipidus
- Caused by insufficient antidiuretic hormone (ADH) leading to excessive urine output.
- Results from central causes (brain injury, surgery) or nephrogenic causes (kidney's insensitive to ADH).
- Symptoms include dehydration, dry skin, confusion, and polyuria (3-20 L/day) alongside polydipsia.
- Laboratory findings show low urine specific gravity and high serum osmolality.
- Care involves monitoring vital signs, daily weights, and fluid/electrolyte management.
Syndrome of Inappropriate Antidiuretic Hormone (SIADH)
- Characterized by excessive ADH leading to fluid retention.
- Causes include tumors, head injury, and certain medications.
- Early symptoms involve headache, weakness, and signs of fluid overload.
- Late symptoms can include confusion, lethargy, nausea, and seizures.
- Care includes fluid restriction, monitoring urine/blood chemistries, and potentially administering diuretics or hypertonic saline.
Thyroid Disorders
Hypothyroidism
- Defined by decreased levels of thyroid hormone, leading to slowed metabolism.
- Common causes include autoimmune thyroiditis (Hashimoto's disease) and treatment for hyperthyroidism.
- Symptoms include fatigue, cold intolerance, weight gain, and bradycardia.
- Severe cases may lead to myxedema, requiring urgent interventions.
Cushing’s Syndrome/Disease
- Results from increased adrenal cortex hormones, often due to medications or tumors.
- Classic symptoms include central obesity, moon face, and hypertension.
- Treatment options focus on addressing the cause, including medication adjustments or surgery.
- Effects of increased androgen can lead to hirsutism and menstrual disturbances.
Diabetes Mellitus (DM)
- A chronic disorder characterized by hyperglycemia due to inadequate insulin production or response.
- Types include Type 1 (insulin-dependent), Type 2 (insulin resistance), and gestational diabetes.
- Symptoms manifest as polyuria, polydipsia, and polyphagia.
- Normal fasting plasma glucose levels are 70-99 mg/dL, with prediabetes at 100-125 mg/dL, and diabetes at ≥126 mg/dL.
- Long-term complications include neuropathy, nephropathy, retinopathy, and increased cardiovascular risks.
Diabetes Treatment and Management
- Focus on education, medication adherence, dietary changes, and physical activity.
- Hyperglycemic Hyperosmolar Syndrome (HHS) is a serious risk in Type 2 diabetes, characterized by extreme hyperglycemia and dehydration.
- Care for long-term complications involves regular monitoring of blood glucose and lifestyle modifications to prevent progression.
Foot Care for Diabetic Patients
- Daily foot inspection and washing in warm water are essential.
- Use lotion on the tops and bottoms of feet, avoiding the spaces between toes.
- Shoes and socks should be worn at all times, and toenails should be trimmed straight across.
- Protect feet from extreme temperatures and avoid crossing legs to maintain circulation.
