ABSTRACT
OBJECTIVES: Evaluate the obstetrical outcomes in the case of women with a history of conization. Determine the role of the cone length in the obstetrical issue. MATERIALS AND METHODS: Retrospective case-control study including the patients (n=39) who had undergone a conization in a university hospital between January 2002 and January 2012. The obstetrical outcomes have been compared to those from a control group (n=78). Into the exposed group the obstetrical outcomes has been compared based on the cone length. RESULTS: Thirty-one patients delivered after a conization (39 deliveries). The obstetrical outcomes have been significantly increased in the exposed group: preterm delivery before 37 weeks gestation (25.6% vs 7.7%, P=0.01), before 32 weeks gestation (15.4% vs 1.3%, P=0.005) and between 28 weeks gestation (10.2% vs 0%, P=0.01), premature onset of labor before 32 weeks gestation (12.8% vs 1.3%, P=0.01) and before 28 weeks gestation (12.8% vs 0%, P=0.01) and preterm premature rupture of membranes before 37 weeks gestation (20.5% vs 1.3%, P<0.001). There was no significant difference for a length cone more than 1.5cm. CONCLUSION: Our study showed that a history of conization is an obstetrical risk factor to consider in the management of a subsequent pregnancy.

To explore the vertical and horizontal distributions of fish larvae near the end of their pelagic period, six light traps were set up over four lunar months at different depths (sub-surface, midwater and bottom) and different habitat types (reef slope: 50 m horizontal distance from the reef crest; frontier zone: 110 m horizontal distance; sandy zone: 200 m horizontal distance) on the outer reef slope of Moorea Island, French Polynesia. The highest captures were in sub-surface traps on the reef slope and the frontier zone, and in bottom traps on the sandy zone and the frontier zone. It is hypothesized that fish larvae move towards the surface near the reef slope to avoid reef-based planktivores and to get into a favourable position for surfing over the reef crest.
