Question
Case 1: The Cold Colonel
You are called upon to visit the ailing Col. Lemon. Before you see him, you speak with three witnesses who were with him
when he fell ill,
Witness statements:
I Ms. Magenta: "Col. Lemon has been hot-blooded for as long as I've known him. But I noticed that he couldn't
seem to keep warm. He kept complaining about being cold..."
I Mr. Olive: “Just between you and me, I've noticed that the old chap has put on quite a bit of weight lately."
I Professor Purple: "The colonel and I used to go on major expeditions together. Now he just doesn't seem to have
the energy to do much of anything."
What are your initial thoughts about the witnesses' statements? Does one hormone come to mind that may be the cause?
You see the colonel and collect some blood to send off to the lab. The analysis comes back as follows:
T3 (triiodothyronine): 0.03 ng/dl (normal: 0.2-0.5 ng/dl)
T4 (thyroxine): 1.1 ug/dl (normal: 4-7 ug/dl)
TSH (thyroid-stimulating hormone): 86 mU (normal: 0.3-4.0 mU/l)
Analyze the results. Why do you think the T3 and T4 are low and the TSH is elevated?
Based upon the witness statements and the laboratory analysis, what is your final diagnosis?
