Med Surg Test 3 Med Surg Test 3 Endocrine II Thyroiditis o Inflammation of thyroid gland o Three types Acute Caused by bacterial invasion of thyroid gland Pain, neck tenderness, malaise, fever, dysphagia Increased WBCs Treatment with ABX Subacute (Granulomatous Thyroiditis) Viral infection of thyroid gland after cold or other upper respiratory infection Fever, chills, dysphagia, muscle or joint pain, pain radiates to ears/jaw Thyroid hard upon palpation enlarged Thyroid function normal, either hypo or hyperthyroidism can occur Pain radiates to the ears and jaw
Chronic (Hasimoto’s Disease) Most common type of thyroiditis Affects more women Autoimmune disorder triggered by bacterial or viral infection Antithyroid antibodies and lymphocytes invade thyroid – selective thyroid tissue destruction When large amounts destroyed – serum thyroid hormones low, TSH increased = hypothyroidism Dysphagia and painless enlargement of gland Diagnosis – circulating antithyroid antibodies, needle biopsy of thyroid gland, serum T3 and T4 and TSH levels vary Treat with thyroid hormone = decrease TSH secretion, decrease size of thyroid Surgery with subtotal thyroidectomy if compresses other structures Simple Goiter o Most common type o Occurs when iodine intake deficient or intake of large quantities of substances are
