This study investigated the efficiency of a sequestration strategy using carbon-based materials to reduce the transfer of organochlorine pesticides (OCPs) from hens to eggs. Specifically, the potential of Kazakhstan-made Shoptykol coal was evaluated by applying 2% (by weight) of this material to OCP-contaminated soil obtained from Kyzylkairat (Almaty region, Kazakhstan). The experiment was conducted by exposure for 45 days of 18 hens, which were divided into three groups depending on their feeding conditions. Laying hens were fed diets containing 10% of soil: for the first group with control soil A, the second group with contaminated soil K, the third group with contaminated soil containing coal. Quantification of pesticide concentrations in egg yolks of laying hens was then performed by gas chromatography mass-spectrometry. Despite the supply of Shoptykol, no significant reduction in OCPs transfer was observed for compounds tested. Thus, the efficiency of Shoptykol coal in reducing the transfer of organochlorine pesticides to animals was not confirmed by our results.

The study aimed to assess the genotoxicity of different DDT contaminated soils (with different amendment types) in benzene extracts. A Salmonella/microsome assay without metabolic activation (-S9) was performed to evaluate the efficiency to initiate the mutations of remediated and non-remediated soils. The number of revertants mutations in his+ in TA100 and TA98 strains were obtained, and compared to soils without DDT, and remediated DDT containing soils. The interpretation of the data suggests that, mutagenic activity was high for the non-remediated soils samples Kyzylkairat and Beskainar, and revealed in the scale as a weak mutagen. Soil samples treated with DARCO, ORBO, Sarg150μm in Kyzylkairat and Beskainar exhibited a decreasing level of mutagenic activity, which is in line with the decreased environmental availability in these soil. Overall, the study indicates that strains TA100 and TA98 are valuable tools for rapidly assessing the potential mutagenicity of soil contaminated with OCPs.

Chronic pelvic pain in a woman with at least one history of caesarean should lead to the diagnosis of parietal endometrioma on a caesarean section scar, even years after. The most suggestive clinical picture is chronic cyclical pelvic pain located near the caesarean section scar associated with a pelvic wall mass. On clinical examination, this painful nodule is most often palpable. In order to support the diagnosis, it is advisable to perform a parietal ultrasound, preferably during menstruation and during the painful crisis; however, ultrasound lesions may also be typical outside menstrual period. The standard treatment consists of a large surgical resection with healthy margins, under general anesthesia., Competing Interests: M. Delannoy déclare n’avoir aucun lien d’intérêts. V.

Objective of the Study: To examine pregnancy outcome in patients with second-trimester vaginal bleeding and to determine a relationship between presumed etiology and perinatal outcome., Material: and methods: A retrospective study performed in Toulouse La Grave CHU between January 1993 and December 1997 including 85 cases of vaginal bleeding from 15 to 27 week's amenorrhea (90 fetuses). Results are compared to overall deliveries during the same period (14941 deliveries)., Results: Mean age at diagnosis is 29.8 years (SD: 5.3 years). Vaginal bleeding in the midtrimester concern 0.57% of deliveries. Abnormal ultrasonographic findings are observed in 73% of patients (placenta previa, subchorionic hematoma, placental abruption) and 81% were hospitalized (mean hospital duration: 18 days). Perinatal mortality was 17.04% and preterm delivery rate 30.6% (vs 11% in the overall patients). Perinatal complications are significatively increased compared with the overall population especially if ultrasonographic examination was abnormal. Second-trimester placental abruption had the worse prognosis. On the other hand, perinatal outcome was comparable when the origin of bleeding was unknown and ultrasonographic examination normal. 41% patients underwent cesarean section., Conclusion: Preterm delivery, perinatal mortality and morbidity are increased in patients with second-trimester vaginal bleeding. The risk is higher when abnormalities are detected at ultrasonography making ultrasonography a useful tool for predicting perinatal outcome.
