Q

Symptoms and signs of primary hyperparathyroidism

A

Symptoms of hypercalcaemia

• Excess calcium makes neurones less excitable
o Slower muscle contractions
o Diminished neuro firing in the CNS

• Hypercalciuria – can lead to dehydration

Stones, thrones, bones, abdo groans, psychic overtones
• Stones – renal colic, kidney stones, gallstones

  • Thrones – refers to the toilet – polyuria, polydypsia dehydration
  • Bones – bone pain, osteopenia, osteoporosis, pathological fractures
  • Groans – constipation, muscle weakness, proximal myopathy, fatigue
  • Psychic overtones – depression, dementia, confusion, inability to concentrate, memory problems

Q

Symptoms and signs of secondary hyperparathyroidism

A
  • Signs + symptoms of CKD
  • Fractures/bone pain
  • Renal osteodystrophy – bone resorption
  • Rickets (bone bossing, rachitic rosary, bowed legs, knock knees)
  • Proximal myopathy

  • Hypocalcaemia – CATs go numb

• Calcification in blood vessels and soft tissues (high levels of phosphate cause it to find and stick to any available calcium, which forms bone-like crystals in places that thy shouldn’t be)

Secondary hyperparathyroidism is basically

Q

What is myxoedema coma?

Sympotms + signs

mx

A

Severe form of hypothyroidism that happens in the elderly

  • Heart failure
  • Hypotension
  • Hypothermia
  • Hyponatraemia
  • Hypoxia
  • Hypercapnia
  • Confusion
  • Coma

Mx

  • IV hydrocortisone (if secondary hypothyroidism due to hypopituitarism) **
  • IV T3
  • Supportive measures - oxygen, rewarming, IVF
  • Treatment of underlying cause (e.g. infection)
  • Replace T3 with T4 after 2-3 days if there is clinical improvement
    • always give hydrocortisone before thyroid hormone, always assume that hypothyrodidism is due to hypopituitarism until TFTs arrive, because hydrocortisone deficiency can kill
