The serum level of anti-Mullerian hormone (AMH), a product from granulosa cells involved in follicle growth, has been shown to correlate tightly with the small antral follicle number (FN) at ultrasonography (U/S) in women who do not have polycystic ovary syndrome (PCOS). Because PCOS is associated with a 2- to 3-fold increase in growing FN, we investigated(More)
BACKGROUND This study revisited the ultrasonographic diagnostic criteria of polycystic ovary syndrome (PCOS) and studied the relationship between the major hormonal and metabolic features of PCOS and the follicle number per ovary (FNPO). METHODS This prospective study included 214 women with PCOS compared with 112 women with normal ovaries. Main clinical,(More)
CONTEXT To date only 18 patients with aggressive pituitary tumors or carcinomas treated with temozolomide have been reported. Increased expression of O6-methylguanine-DNA-methyltranferase (MGMT) has been suggested to predict resistance to temozolomide. OBJECTIVES The objective of the study was to describe the antitumoral efficacy and toxicity of(More)
Pituitary adenomas are currently classified by histological, immunocytochemical and numerous ultrastructural characteristics lacking unequivocal prognostic correlations. We investigated the prognostic value of a new clinicopathological classification with grades based on invasion and proliferation. This retrospective multicentric case-control study(More)
CONTEXT To date, no study reported long-term follow-up results of gamma knife stereotactic radiosurgery (SR). OBJECTIVE The aim of the study was to determine long-term efficacy and adverse effects of SR in secreting pituitary adenomas. DESIGN We conducted a retrospective study of patients treated by SR in the center of Marseille, France, with a(More)
CONTEXT Few data are available on pregnancy outcomes in women with acromegaly. STUDY DESIGN This was a retrospective multicenter study. PATIENTS The study included 46 women with GH-secreting pituitary microadenomas (n = 7) or macroadenomas (n = 39). Their mean age was 31.7 yr (±4.5 yr). Incomplete transsphenoidal surgical resection (n = 39) and(More)
CONTEXT Germline mutations in the aryl hydrocarbon receptor interacting protein gene (AIP) have been identified in young patients (age ≤30 years old) with sporadic pituitary macroadenomas. Otherwise, there are few data concerning the prevalence of multiple endocrine neoplasia type 1 (MEN1) mutations in such a population. OBJECTIVE We assessed the(More)
OBJECTIVE To elucidate whether the negative effect of obesity on the serum inhibin B level that we previously reported is specific or not to polycystic ovary syndrome (PCOS) and whether it may explain the wide interindividual variability in serum inhibin B levels found in patients with PCOS. DESIGN Prospective study. SETTING Reproductive endocrinology(More)
OBJECTIVE To explore the abnormalities of serum inhibin isoform concentrations in a large group of patients with polycystic ovary syndrome (PCOS) and to evaluate the influence of body mass index (BMI), age, LH, and androgens on serum inhibin levels. DESIGN Prospective study. SETTING Reproductive endocrinology unit of an academic medical center. (More)
Although benign, pituitary adenomas frequently invade adjacent sinuses or recur after first surgery. To date, there is no histological marker predictive of recurrence. Angiogenic factors are candidate markers. Endocan is a proteoglycan secreted by endothelial cells, associated with an aggressive behavior in several tumor types. Endocan expression was(More)
