RESUMO
We present a case of a 33 year old man who underwent a thyroidectomy due to papillary thyroid carcinoma, with a reversible paresis of both vocal cords after radioiodine therapy. The patient had no previous lesion in laryngeal nerves. Paralysis of the vocal cords is a rare complication of the 131I administration and generally occurs more frequently when there is already some type of lesion in the recurrent laryngeal nerves. The paper reviews the literature on this type of complications.

Exponemos el caso de un varón de 33 años, intervenido de un carcinoma papilar de tiroides, que presentó de forma transitoria una parálisis parcial de ambas cuerdas vocales tras la administración de una dosis ablativa de radioiodo. El paciente no tenía lesión previa de los nervios laríngeos recurrentes. La parálisis de las cuerdas vocales es una complicación poco frecuente de la administración de 131I y suele ocurrir más frecuentemente cuando ya existe algún tipo de lesión en los nervios laríngeos recurrentes. Realizamos una revisión de los casos publicados en la bibliografía sobre este tipo de complicaciones. (AU)

A stenosing antral lesion was diagnosed in a patient with previous ulcer dyspepsia. Radiology, gastroscopy and serology made the diagnosis of gastric syphilis. The lesion disappeared with specific therapy. We present this case because of its rare gastric onset (0.3%) among visceral syphilis, though sexual transmission diseases are increasing nowadays.

The fluorimetric properties of the oxime, thiosemicarbazone, azine and 2-pyridylhydrazone of 3-hydroxypyridine-2-aldehyde have been studied; quantum yields have been measured in ethanol-water and ethanol-dimethylformamide media. Two kinetic methods are described for the determination of trace amounts of manganese(II), based on its catalytic effect on the oxidation of the thiosemicarbazone and of the azine by hydrogen peroxide. The reactions are followed by measuring the rate of change of the fluorescence. The calibration graph is linear over the manganese range 5-50 ng ml with a precision of +/- 3.0% for the thiosemicarbazone, and 0.4-0.9 mug ml with a precision of +/-2.0% for the azine. Interferences by foreign ions have been investigated.
