【非選題】 A 28-year-old lady visited your office with palpitation, excessive sweating and body weight
loss for 7 kg in the last 6 months. She stated that her appetite was good, but she had
experienced 2-3 bowel movements a day, and also suffered from oligomenorrhea. Her body
height was 166 cm, body weight 46 kg, blood pressure 140/66 mmHg, respiratory rate
24/min, and pulse rate 106/min. She appeared nervous. Skin appeared velvety. Thyroid was
mildly enlarged; vascular bruit was audible over neck. Third heart sound was audible over
the apex and a grade 2/6 systolic murmur audible along the upper left sternal border. Mild
hand tremor was also noted. The rest of the physical examination was normal. What is your
tentative diagnosis? What will be your work-up to confirm the diagnosis and what will be
your therapeutic plan when the diagnosis is confirmed? (20%)
