Yоu hаve а 31-yeаr-оld female cоme into your office. It is 45-degrees outside and you notice she is not wearing a coat. She states she has been feeling warm all the time though she does not actually have a fever. She complains of weight loss, thinning hair, difficulty sleeping, and feeling anxious for the last 6 months. She complains of palpitations and sometimes feeling like her heart will beat right out of her chest. She complains of her eyes feeling gritty. On exam you note that she is 66 inches tall and 105 lb. This is down from 130 lbs when you saw her for a well-woman physical 3 years ago. You see a slight rim of the sclera above her iris on both eyes. She has a slight lid lag when you ask her to look downward. Her neck shows a diffusely enlarged thyroid gland. It is non-tender. There are no discrete nodules. Cardiac exam shows a regular rate of 105 beats per minute. BP 135/85. No murmurs. The rest of her exam is normal except for very brisk patellar reflexes. A. You suspect thyroid disease. Are you suspecting hyperthyroidism or hypothyroidism? B. The most common cause of her condition is an autoimmune disease that produces an abnormal antibody that mimics a naturally occurring hormone. What hormone does this antibody mimic? C. You check her TSH. Is it high, normal, or low? D. You do a radioactive iodine scan. Do you expect to see increased diffuse uptake, nodular uptake, or no uptake of the tagged iodine?
