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)
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)
Kallmann syndrome (KS) associates congenital hypogonadism due to gonadotropin-releasing hormone (GnRH) deficiency and anosmia. The genetics of KS involves various modes of transmission, including oligogenic inheritance. Here, we report that Nrp1(sema/sema) mutant mice that lack a functional semaphorin-binding domain in neuropilin-1, an obligatory coreceptor(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)
We report two sisters with profound insulin resistance associated with a novel heterozygous missense mutation in exon 19 (His1130Arg) of the insulin receptor gene. The eldest was seen after puberty at age 15 and she presented a severe form of polycystic ovary syndrome (PCOS) with biological hyperandrogenism (HA) mimicking a virilizing tumour. However, she(More)
In patients with severe traumatic brain injury (TBI), a growth hormone deficiency (GHD) is frequent and may contribute to the cognitive sequelae and reduction in quality of life (QoL). Recent studies have suggested that GH replacement therapy (GHRT) can improve processing speed and memory. The aim of the study was to analyze the efficacy of GHRT on(More)
Increased abdominal adipose tissue (AAT) mass, as most reliably measured by waist circumference, in pubescent girls positively correlates with insulinemia, circulating insulin-like growth factor 1, insulin resistance, androgenemia, and both plasma luteinizing hormone and estradiol levels. Because insulin resistance and androgen excess regularly accompany(More)
The human chorionic gonadotropin test is more powerful than the gonadotropin-releasing hormone agonist test to discriminate male isolated hypogonadotropic hypogonadism from constitutional delayed puberty Abstract Objective: The effectiveness of biological investigations aiming at discriminating isolated hypogonado-tropic hypogonadism (IHH) from(More)
