Keeping collecting device in liquid medium is mandatory to ensure optimized liquid-based cervical cytologic sampling.

Objective: To determine the impact of not keeping the collecting device in liquid-based cytology. Loss of material was computed from a pair of subsamples from the same cervical scrape. One subsample was obtained by rinsing the collecting device in one vial and the other by discarding it in another vial.

[Oxytocinase: levels in normal and pathological pregnancies].

The author has determined the levels of plasma oxytocinase in a series of normal and pathological pregnancies. It appears from studying these levels that it is useful to measure the oxytocinase particularly in cases where there is failure of intra-uterine growth.

[Celioscopic sterilizations with Yoon rings. 300 cases. Immediate complications, effectiveness and reversibility].

The authors report on a series of 370 sterilisations using Yoon's rings, of which 300 were carried out laparoscopically. They confirm the efficiency of the method and its safety because there was only minimal operative morbidity. On the other hand this technique offers the possibilities of reversal of sterilisation in such a way that it should be the preferred method to be used systematically when a young woman is being sterilised.
