Évaluation d'un programme alternatif de formation de médecins généralistes en Gynécologie et Obstétrique au Sénégal

Afin de lutter contre la mortalité maternelle dont les taux restent encore élevés avec 401 pour 100 000 naissances vivantes en 2005, le Sénégal a mis en œuvre dans la continuité de ses stratégies novatrices de délégation de compétences pour renforcer l’accès aux soins obstétricaux et néonataux d’urgence, un programme alternatif de formation au D.E.S de Gynécologie et Obstétrique de médecins généralistes basés dans les zones éloignées. A partir du curriculum du programme classique, ce programme allie l’enseignement à distance à l’aide des Nouvelles Technologies de l’Information et de la Communication, des stages pratiques dans les sites du CHU, le coaching par les enseignants du CHU dans les Centres de santé où officient les médecins apprenants, des évaluations en ligne et les évaluations annuelles formelles du programme de formation classique. Il a été mis en œuvre dans deux districts du Sénégal par la Chaire de Gynécologie et d’Obstétrique du CHU de Dakar. Ce travail présente l’évaluation à mi-parcours de ce programme en analysant son implantation et ses effets à travers une étude de cas, grâce à des données qualitatives et quantitatives. Les résultats montrent : une évolution favorable des indicateurs sanitaires dans les deux sites du programme comparativement aux sites témoins, une augmentation du niveau de connaissance et de compétence des apprenants, et un niveau de satisfaction élevé des deux apprenants, des enseignants et des bénéficiaires. Cependant, des améliorations sont à apporter dans la mise en œuvre du programme en particulier en termes d’opérationnalisation des innovations pédagogiques, de coordination et de pérennisation par le Ministère de la Santé.

Fertility preservation: Successful transplantation of cryopreserved ovarian tissue in a young patient previously treated for Hodgkin's disease

Cryopreservation of ovarian tissue is now offered as an experimental procedure to preserve the fertility of young patients with a high risk for premature ovarian failure resulting from cancer therapy. This is the only available option to preserve the fertility of prepubertal patients treated with gonadotoxic chemotherapy. At present, thousands of patients all over the world have undergone this procedure with the hope of later restoring their fertility. Although the efficiency of the transplantation of cryopreserved ovarian tissue to restore ovarian function has been established, reports of pregnancy are still very scarce. Here, we describe the second published full-term spontaneous pregnancy after an orthotopic and heterotopic transplantation of cryopreserved ovarian tissue in a 31-year-old woman previously treated by conditioning therapy for bone marrow transplantation for Hodgkin's disease. This birth gives compelling evidence for the graft origin of the gamete and confirms the efficacy of ovarian tissue transplantation in restoring human natural fertility after oncological treatment. This case report stresses the importance of proposing the ovarian tissue cryopreservation procedure to all young patients who require potentially sterilizing treatment, with all alternative options to preserve fertility being duly taken into consideration.

Unpredictable Cases of Complicated Ovarian Hyperstimulation in IVF

Objective-To characterize a subpopulation of complicated cases of ovarian hyperstimulation syndrome (OHSS). Method-Descriptive retrospective study. Results-0.75% of our IVF-ET population suffered from OHSS. Among this group, 33% did not exhibit any recognized risk criteria of OHSS in terms of infertility characteristics and ovarian response to exogenous gonadotrophins. Only severe (ascites) OHSS cases were considered (n = 5) in this study. Previous IVF-ET attempts had been uneventful and during the complicated trial, estradiol peak levels and numbers of oocytes retrieved remained below 2,500 pg/mL (conversion factor to SI unit, 3.671) and 10, respectively. In all cases, the luteal phase was supplemented by hCG and all patients became pregnant. A threshold level of exogenous and/or endogenous hCG seems to be responsible for the occurrence of OHSS. Conclusion-One-third of the patients developing an ovarian hyperstimulation syndrome after IVF-ET had not previously shown risk criteria. A causal role of exogenous and/or endogenous hCG is suggested.

Hardening of zona pellucida of mouse oocytes and embryos in vivo and in vitro

Objective - To evaluate the effect of in vitro culture on zona pellucida resistance in mouse oocytes and embryos. Method-Zona pellucida resistance was assessed by comparing duration of zona lysis in the presence of alpha- chymotrypsin. The effects of artificial or physiological conditions of development were evaluated by comparing embryos in vitro with those left to reach the same stage of development in vivo. Results - The time required for zona lysis of oocytes increased after 2, 9.4, and 48 hours in vitro (P < .001). The same observation holds true for oocytes left in vivo during 24 hours. Fertilization both in vivo and in vitro induced a major increase in zona resistance. At the two-cell stage, in vitro culture did not harden the zona pellucida. At the morula stage and beyond, enzymatic lysis was slightly longer in vitro as compared to that of similar stages recovered from the genital tract. Conclusions - Our data indicate that in vitro culture conditions do not modify zona hardening in oocytes and only slightly increased zona resistance from the morula stage on.
