“…A temporary disturbance of gland function in severe cases of de Quervain's thyroiditis is described by many writers (Crile and Rumsey, 1950;McConahey and Keating, 1951;Lindsay and Dailey, 89 1954;Harland and Frantz, 1956;Izak and Stein, 1956;Czerniak and Harell-Steinberg, 1957;Woolner et al, 1957;Volpe, Johnston, and Huber, 1958). In such cases there can be transient symptoms indicative of hyperthyroidism; the plasma protein-bound iodine level tends to be high, but, in contrast, iodine uptake by the gland in vivo tends to be diminished.…”
