[Endometriosis and fertility preservation: CNGOF-HAS Endometriosis Guidelines].
Fertility preservation (FP) techniques are progressing rapidly these past few years thanks to the oocyte vitrification. Indication of FP techniques is now extended to non-oncological situation that may induce risk of premature ovarian failure. Ovarian endometriosis can lead to premature ovarian failure and further infertility due to the high risk of ovarian cysts recurrence and surgery. To date, there is no cohort study regarding FP and endometriosis as well as no recommendation. Our purpose is to review the arguments in favor of FP in this specific area and to elaborate strategies according to each clinical form.
A real case of a steel lattice shell suffering a fire was studied. Based on the theory of field modeling, fire dynamic simulator (FDS) was used to identify the temperature field. The damage mechanism of the structure was determined by FEM analysis. After damage assessment, the shell was repaired with the pipe-encasement method. Finally, field test was employed to check the capacity of the structure after repair. The numerical study results indicate that the damage assessment agrees well with field inspection, verifying the accuracy of fire numerical simulation and FEM analysis. The field test results prove that the pipe-encasement method is secure and reasonable, and the repaired shell is safe.
