Clinical follow-up of the first SF-1 insufficient female patient

ObjectiveSteroidogenic factor 1 (SF-1/NR5A1) plays a crucial role in regulating adrenal development, gonad determination and differentiation, and in the hypothalamic-pituitary control of reproduction and metabolism. In men (46, XY), it is known that mutations in SF-1/NR5A1 gene cause a wide phenotypic spectrum with variable degrees of undervirilization. In recent years, the role of SF-1 in the ovarian function was increasingly discussed and alterations in the gene were related to primary ovarian insufficiency. We describe the follow-up of a 46, XX affected woman with a SF-1 mutation and by comparing our case with the known manifestations reported in the literature, we try to further elucidate the function of SF-1 in the ovary.ResultsDuring infancy, adrenal insufficiency was the only clinical sign of the loss-of-function as ovarian development and function seemed normal. To date, this young woman aged 16.5 years shows normal growth, normal BMI and psychomotor development, has a normal puberty and regular menstruation.ConclusionThis report shows one, to date uniquely described, phenotypic variant of SF-1 mutation in a 46, XX affected person with adrenocortical insufficiency but no ovarian dysfunction nor disturbance of pubertal development. To follow the natural history of SF-1 mutation in a 46, XX individual will further shed light on its role in the ovarian function and thus will help to counsel affected patients in future.     

Management of accessory renal arteries during aneurysm repair in a patient with end-stage renal failure

The presence of accessory renal artery is a frequent anatomic variation that can challenge abdominal aortic aneurysm (AAA) repair. Here, we show an image of an abdominal aortic aneurysm extended to multiple accessory renal arteries in a patient known for an end-stage renal failure. This case raises the questions of the criteria that should be taken in consideration for an optimal management of accessory renal artery during AAA repair.     

Biological and radiological exploration and management of non-functioning pituitary adenoma

Non-functioning pituitary adenoma may be totally asymptomatic and discovered “incidentally” during radiological examination for some other indication, or else induce tumoral signs with compression of the optic chiasm and pituitary dysfunction. Non-functioning adenomas are mainly gonadotroph, but may also be “silent”. Treatment strategy depends on initial clinical, biological, ophthalmological and radiological findings. The present French Society of Endocrinology Consensus work-group sought to update the pitfalls associated with hormone assay and outline a hormonal exploration strategy for diagnosis and follow-up, without overlooking the particularities of silent adenoma. We also drew up basic rules for initial exploration and radiological follow-up of both operated and non-operated pituitary adenomas.
