[Obstetric management after ectopic pregnancy in the caesarean section scar: a case report and review of literature]. / Prise en charge obstétricale après grossesse ectopique intracicatricielle: à propos d'un cas et revue de la littérature.

We report the case of a patient who came out pregnancy twelve months after medical and surgical treatment of an ectopic pregnancy in a previous caesarean section scar. The preconceptional management consisted in a saline infusion sonohysterography and a pelvic magnetic resonance imaging. Judging the risks of abnormal placental insertion to be higher in this case compared to a simple caesarean section, a careful ultrasonography with color doppler imaging was carried out. The myometrium fragility caused by the ectopic pregnancy in the caesarean section brought us to recommend a prophylactic caesarean section around 37. The high risks of hemorrhage required a medical center with embolization possibilities. A review of literature in order to define the medical care adapted in this case was come out.

Induction of homologous low temperature and ABA-responsive genes in frost resistant (Solanum commersonii) and frost-sensitive (Solanum tuberosum cv. Bintje) potato species.

A DNA fragment corresponding to a low-temperature- and ABA-responsive gene (Scdhn1) was amplified by PCR from genomic DNA of a wild, frost-resistant potato species, Solanum commersonii. A homologous gene (Stdhn1) was identified in Solanum tuberosum cv. Bintje, a frost-sensitive domesticated potato cultivar. The expression of the gene was studied during low temperature and ABA treatments in both Solanum species. The analysis revealed that both low temperature and ABA lead to the accumulation of a 1 kb transcript that corresponded to the PCR fragment. The induction of the gene was relatively rapid and maximum amounts of the transcripts were detected already after 1 day and 7 h of treatment with low temperature and ABA, respectively. Previous results have shown that there is no increase in the amount of endogenous ABA in S. tuberosum during low-temperature treatment, which indicates that two independent signalling pathways lead to the induction of this gene.
