Baligobin (29 March, p. 727) and agree that their results of laparoscopic sterilization are depressing and raise doubts about the usefulness of this procedure. We feel, however, that there are several reasons for the high incidence of complications and that it would be a pity to decry the operation on the basis of suc...

Further evidence for an endogenous origin of faecal iodine is obtained from balance studies in patients with abnormal thyroid function (Harrison et al., 1965a). Patients with thyrotoxicosis excrete significantly more iodine in the faeces than normal, ranging from 21 to 72 ,tg/ day...
