Background: In low-resource settings, where abortion is highly restricted and self-induced abortions are common, access to post-abortion care (PAC) services, especially treatment of incomplete terminations, is a priority. Standard post-abortion care has involved surgical intervention but can be hard to access in these areas. Misoprostol provides an alternative to surgical intervention that could increase access to abortion care.

The aim of our work was to objectify and quantify the mechanical benefits of healing with regards to tearing meshes off of tissues and maximal resistance after cicatrization. In vivo, we tested the mechanical gain in resistance by healing after implantation of a Prolene mesh. We measured the value of forces when traction was exerted until mobilization at different stages of cicatrization.

Intra-uterine arteriovenous malformations are a possible etiology of persistent metrorrhagia especially in the event of a history of miscarriages, cornuale pregnancy, molar pregnancy or gravidic trophoblastic diseases. We report 4 cases of patients having an intra-uterine arteriovenous malformation. The diagnosis of such lesions calls upon first intention Doppler echography.
