ENDOCRINE Thyroid stations: Hx presentation:
• Neck lump • Eye problems – diplopia • Heat/Cold intolerance • Tremor • Weight change • Diarrhoea, constipation • Palpitations • Oligomenorrhoea
Examination
• Hands – acropachy, tremor, sweaty • Pulse – tachy/ AF • Eyes – position, chemosis, ophthalmoplegia • Neck exam incl swallowing, LNs, retrosternal goitre and bruit • Reflexes • Proximal myopathy • Pretibial myxoedema
What is Grave’s disease? Autoimmune Dx with TSHR-Abs which hyperstimulate the thyroid and also bind to soft tissues in the orbit, leading to a hyperthyroid state and thyroid eye disease. It is the most common cause of hyperthyroidism. Is it more common in women (5x). The antibodies can also direct. It presents with symptoms of hyperthyroidism such as weight loss, anxiety, tremor, heat intolerance or tachycardia, neck swelling from a diffusely enlarged mildly tender goitre, and Grave’s eye disease, with proptosis, exophthalmos, chemosis and complex ophthalmoplegia. What is the treatment for Grave’s disease? Symptoms can be initially controlled with beta-blockade. I would consider an urgent ophthalmology opinion if there was any visual loss, ophthalmoplegia or inability to close the eyes, and eye lubricants, steroids, tarsorrhaphy or orbital irradiation or decompression. Treatment for Grave’s is through anti-thyroid medications such as carbimazole or propylthiouracil, radioactive iodine therapy, or partial or complete thyroidectomy. All treatments have their downsides; antithyroid drugs cause rash, myopathy, alopecia, agranulocytosis and aplastic anaemia and liver problems, radioactive iodine is contraindicated in pregnancy, iodine allergy, radiation risk (incontinent), solitary nodules and in eye disease which it may worsen, surgery has complications such as vocal cord paralysis and hypoparathyroidism.
