[Data analysis and quality control in radioimmunoanalysis. II. Evaluation of the internal and external quality in the quantification of pituitary gonadotropins].

The procedures for a systematic evaluation of the quality control of radioimmunoassay in general were described previously. In this report we present the parameters of quality control and their application to the radioimmunoassay (RIA) of pituitary gonadotrophic hormones, luteinizing hormone (LH) and follicle stimulating hormone (FSH) in serum. We present the results obtained in the intra-assay variation for the measurement of the pituitary gonadotrophic hormones in serum (LH and FSH) from 1983 to 1989. The results on bias and the inter-laboratory assessment through an external quality control scheme during the same period are also presented.

[Spontaneous pneumopyelography: ureterocolic fistula caused by rectosigmoid carcinoma].

We present a case of ureterocolic fistula, secondary to a rectosigmoid carcinoma. The infrequency of these ureterocolic fistulae, contrasts with the more usual vesicointestinal ones. In our case, the diagnosis of pathological communication arose from the presence of gas in the excretory tract, after ruling out all those processes which could have led to a similar situation. In agreement with the world literature consulted, we confirm the great difficulty in tracing the course of the fistula by the usual means of diagnosis, in view of the minimal size of the pathological communication and the frequent obstructive behaviour of the fistula itself.
