Unexplained decrease in measured oxygen saturation by pulse oximetry following injection of Lymphazurin 1% (isosulfan blue) during a lymphatic mapping procedure.

A rare case of alteration in measured pulse oximetry during a lymphatic mapping procedure for cervical carcinoma is reported. Over a 5-min period following injection of perilesional Lymphazurin 1% dye (3 ml total), a profound pulse oximetry desaturation was observed. Concomitant arterial blood gas determinations confirmed patient's well-being. Interaction of this agent's absorptive spectroscopy and wavelengths used to measure oxygen saturation by commercial pulse oximetry devices is suspected.

Administration of a gonadotropin releasing hormone analogue in oligozoospermic infertile males.

This study investigated the stimulatory potential of a superactive gonadotropin releasing hormone analogue in idiopathic oligozoospermia. In a double-blind trial, 19 men were randomized to receive buserelin (D-Ser(TBU)6-GnRH ethylamide) in one of two dosages or saline, twice weekly, for twelve weeks. Treatment did not lead to a significant increase in serum concentrations of the pituitary gonadotropins or in sperm concentrations. However, in the dosages and schedules investigated, there was no inhibitory effect of the analogue. Further assessment of this approach is suggested.

Disappearing hypercalcaemia.

Four women presented with symptomatic hypercalcaemia and raised concentrations of serum parathyroid hormone (PTH). In each case, serum calcium returned spontaneously to normal. In two patients serum PTH also fell to the normal range and biochemical relapse has not occurred despite prolonged follow-up. In the others, serum PTH remained elevated and subsequent symptomatic hypercalcaemia necessitated parathyroidectomy. In the first two cases, autoparathyroidectomy is the most likely explanation; the initial fall in serum calcium in the other two patients is unexplained. Large fluctuations in serum calcium may occur in some patients with hyperparathyroidism and prolonged and careful observation is required when this occurs.
