[Iodine deficiency in Salzburg in spite of iodized table salt prophylaxis]. / Jodmangel in Salzburg trotz Jodsalzprophylaxe.

Urinary iodine excretion was determined in 293 medical technical and nursing students in hospitals of the province Salzburg. The average urinary iodine excretion amounted to 46.6 +/- 18 micrograms iodine per gram creatinine. 67.6% of the students showed a deficiency of iodine II, whilst 98.3% had a deficiency of iodine I according to WHO criteria. Urinary iodine levels and natriuria are closely correlated, indicating that iodized table salt probably constitutes the most important source of iodine. 73 of the students had a palpable giotre, 10 of these being nodular. Our investigations, together with those of Innsbruck, Graz and Vienna, demonstrate the existence of generalized iodine deficiency in spite of iodized salt prophylaxis, which has been legally enforced in all of Austria since 1963. Iodized table salt prophylaxis has, thus, led to a drastic decrease in goitres in children, but is not sufficient to eliminate iodine deficiency in adults. An increased level of iodization of table salt, as has been put into force in Switzerland, must be called for in Austria, too.

[Biochemical data in the fluids of cystic degenerated euthyroid goiters (author's transl)]. / Biochemische Befunde in Zystenflüssigkeiten zystisch degenerierter euthyreoter Strumen.

Examinations of sera and cyst fluids in patients with cystic degenerated euthyroid goiters showed significant differences between the values of the cyst fluids and sera for almost all of the chemical substances. In the brown cyst fluids there are mostly higher values compared with the appropriate sera. Autolysis, diffusion and resorption, metabolic changes and, in the case of thyroid hormones, active incretion by wall-forming thyroid tissue, are the reasons for these differences in the concentrations.
