Follow-up measurements of TBII allow, in half of the patients, assessment of the prognosis of GO and, therefore, could be of additional help for the disease management.

Thyroid sonography was used to assess 2322 patients attending our clinic over a 3-year period. Sonography, in combination with clinical and laboratory findings, enabled us to detect autoimmune thyroiditis in 123 patients, 67 of whom could be classified as euthyroid, 17 as latent hypothyroid, and 39 as overtly hypothyroid. Consequently without the use of sonography (or thyroid antibody measurements) it would not have been possible to make a diagnosis in over half of our patients with autoimmune thyroiditis. Sonography was also of considerable value in establishing the absence of autoimmune thyroiditis as out of the 2322 patients we examined, autoimmune thyroiditis could be excluded on the basis of sonography alone (absence of diffuse hypoechoicity) in 1962 (84%). Thyroid volume ranged from < 5 to 112 ml with the majority of patients having a volume of 21-30 ml and the overtly hypothyroid group showing a shift to smaller volumes. The data suggested that thyroid volume changes over the range of the disease from euthyroid to overtly hypothyroid.

Background: To broaden the range of outcomes that we can measure for patients undergoing treatment for oncological and other chronic conditions, we aimed to validate a questionnaire measuring self-reported autonomic regulation (aR), i.e. to characterise a subject's autonomic functioning by questions on sleeping and waking, vertigo, morningness-eveningness, thermoregulation, perspiration, bowel movements and digestion.

We studied the influence of a moderate homeopathically prepared thyroxine dilution (final concentration in the basin water 10–¹³ parts by weight) on the metamorphosis of lowland Rana temporaria which had been hyperstimulated with thyroxine. Two groups of animals were pretreated by immersing them in a molecular thyroxine dilution (10–⁸ parts by weight). This pretreatment speeds up development, as is well known. In accordance with the homeopathic/isopathic idea of detoxication or cure, the same hormone was then diluted and agitated in successive steps for further treatment. This homeopathically prepared dilution was administered at 24-hour intervals to one of the groups. An analogously prepared blank solution was used for the control group. Our hypothesis, which was derived from earlier studies, was that animals treated with the test solution would metamorphose more slowly than the control animals, i.e. that the homeopathically prepared thyroxine would have a ‘curative’ effect. In this new series of experiments this hypothesis was examined by 3 independent researchers. In the experiments carried out by 2 of the 3 researchers the number of animals that reached the fourlegged stage at defined points in time was smaller in the group treated with homeopathically prepared thyroxine. In the third laboratory no difference was found between the groups. However, the overall inhibiting effect was statistically significant and more pronounced than in earlier, less promising studies and in parallel experiments in which nonprestimulated animals had been used. Other studies carried out by the 3 researchers involved animals from highland biotopes, where the natural environment probably induces a greater sensitivity towards thyroxine or higher thyroxine levels. These animals reacted to the homeopathically prepared thyroxine with a slowing down of metamorphosis, even when they had not been prestimulated with a molecular dose of the hormone. This effect was observed in all 3 laboratories and is consistent with the results of previous studies.
