[Ovarian stimulation and granulosa cells tumors, about 5 cases]

Ovarian stimulation for the treatment of the infertility expose the patient and its ovaries to above physiological high concentrations of gonadotrophin. The major complications of the use of these therapeutic are the ovarian hyperstimulation and the multiple pregnancies. We describe 3 cases of granulosa cells tumors of the ovary after stimulation with the clomifene and / or gonadotrophin. A review of the literature does not allow to make the link between these therapeutic and tumoral pathology, however animal experimentation showed a relation between the exposition with gonadotrophin and the granulosa cells tumors. The most confirmed hypothesis being able to explain this association in human race is the increase of intra follicular gonadostimulins which is oncogen for the granulosa cells

[Transvaginal ultrasound of the cervix in the estimation of severity of premature labour]

Premature labour is a frequent situation it complicates about 6% of births, with increasing perinatal morbidity and mortality. The purpose of this study is to analyze the place of the ultrasound of the cervix in the coverage of a premature labour and the evaluation of the severity of the premature labour, being able to have therapeutic implications. It is about a prospective study on 48 patients presenting a premature labour between 28 and 35 weeks realized in the service of maternity in Hddi Chaker hospital of Sfax for a period of 7 months going from January till July, 2005. In our study 23 patients presented an ultrasonographic cervical length
