A prospective study of thyroid ultrasound scan in the clinically solitary thyroid nodule.
Thyroid ultrasound differentiates solid from cystic lesions, solitary nodules from multinodular and diffuse enlargement, and extrathyroidal lesions. Two hundred consecutive patients with a clinically solitary thyroid nodule were investigated by ultrasound examination, thyroid function test, and thyroid auto-antibodies. Patients with confirmed solitary solid, or mixed solid and cystic nodules underwent surgery as well as those with cysts, multinodular or diffuse goitres with pressure symptoms, recurrent haemorrhage or relapsing hyperthyroidism. Comparison between the ultrasound and ultimate pathological findings in the 101 patients who underwent surgery showed that they were in agreement in 96 cases. The remaining 99 patients with cystic, multinodular or diffuse lesions have been followed up for a mean of two years. Nearly 50% of patients with a clinically solitary thyroid nodule have avoided surgery.
An alternative method of assessing changes in salivary flow: comparison of the effects of clonidine and tiamenidine (HOE 440).
An established method for collecting uncontaminated parotid saliva has been applied to assessment of salivary flow rate. Following single doses of 0.3 mg clonidine and 1.0 mg tiamenidine (HOE 440) changes in blood pressure, heart rate, sedation (assessed by a self-rating scale) and salivary flow were followed in nine normal subjects. Both drugs produced a fall in systolic and diastolic blood pressure, sedation, depression of salivary flow and a lowering of heart rate. These changes were maximal between 2 and 6 h and were more marked after clonidine than after tiamenidine. As tiamenidine 1.0 mg did not produce a hypotensive effect equivalent to clonidine 0.3 mg direct comparison of side-effects attributable to these agents proved difficult. The evidence suggests, however, that tiamenidine would cause sedation and reduction in salivary flow comparable to clonidine if given in an equivalent hypotensive dose.
