[Ultrasonographic evaluation of the thyroid palpation method in determining its dimensions in children and adolescents].
The authors analyze the diagnostic value of thyroid palpation method (two modifications) comparing its results with those of ultrasonographic volumetry. The study involved 118 children aged 5 and 14 of both sexes living in regions endemic for goiter. The thickness of thyroid isthmus was found virtually the same no matter how greatly the gland was enlarged. The results proved the necessity of age-specific corrections in the criteria of current interpretation of palpation data: the first degree in preschool children was most often indicative of thyroid hypertrophy whereas in the pubertal age it was just a variant of normal size. Interpretation with due account of these amendments improved the reliability of diagnostic value of palpation, its sensitivity being 63 +/- 6, specificity 67 +/- 6, and accuracy 65 +/- 4%. When the results of palpation are adequately interpreted, the examinees' age and sex and the method of examination proper do not influence the data accuracy. The sensitivity of palpation in detection of nodules up to 10 mm in diameter proved to be null (in 6 of the 81 examined adolescents sonographic signs of encapsulated formation were seen in the thyroid). Bearing all this in mind, the authors discuss differentiated approaches to management of children and adolescents with the first degree of palpated enlargement of the thyroid.
