Pregnancy is associated with an increased risk of tumor growth in macroprolactinoma leading to discuss surgery in such cases.Objectives: Impact of pregnancy on prolactin secretion and tumor growth in a cohort of women with macroprolactinoma, including large tumors >20 mm, and medically treated.Methods: Retrospective study of all the women with macroprolactinomas diagnosed in two university hospitals, treated by dopamine agonist...

Although most pituitary tumors are benign, some are invasive or aggressive. In the absence of specific markers of malignancy, only tumors with metastases are considered malignant. Recently we identified a marker set of invasion, proliferation and aggressiveness in prolactin (PRL) tumors1. We will present the prognostic value of histological and molecular markers in PRL tumors and their usefulness in other types of pituitary tumors.Forty-five patients, 23...

Context: Differentiating Cushing’s disease (CD) from pseudo-Cushing’s syndrome (PCS) is one of the most challenging problems since no biological test is yet perfect. Almost 30 years ago our group demonstrated the interest of 4 mg i.v. dexamethasone suppressing test (DST) to differentiate obese patients to CD.Objective: To reevaluate the diagnostic accuracy of the 4 mg i.v. DST in carefully selected patients with PCS and CD.<p class="abstext...

Introduction: Pituitary incidentalomas (PIs) defined as pituitary tumors discovered by systematic neuroimaging constitute an increasingly clinical problem. Most of PIs are nonfunctioning tumors (NFPIs) with systematic investigation revealing visual and/or endocrinological impairment in some patients while others remained asymptomatic. If the therapeutic management is well codified for functioning PIs and symptomatic NFPIs, a debate still remain for asymptomatic NFPIs between s...

Objectives: Long-term results of medical treatment of macroprolactinoma in children and adolescents (<20 years).Patients and methods: Retrospective analysis of all the cases of macroprolactinoma occurring in children and adolescents, medically treated in two university centers.Results: 38 patients, 25 girls 13 boys, age at diagnosis: 15.7±2.8 years (only two cases before 12 years). At diagnosis, 2/3 presented with headache...

Introduction: CD is a rare disease. Our aim was to describe demographic and clinical characteristics together with initial management of patients with CD.Patients and methods: A retrospective analysis of 437 CD patients diagnosed between 1996 and 2009, followed in 5 tertiary centers (Bordeaux, Grenoble, Lyon, Marseille, Paris) was performed in the frame of the national program for rare diseases.Results: 347 (80%) were women. Mean a...

Context: Ectopic GHRH secretion is a rare cause of acromegaly described mainly in isolated case reports.Setting: From the registry of the sole laboratory performing plasma GHRH assays in France, we identified cases of ectopic GHRH secretion presenting with acromegaly between 1983 and 2008.Patients: In total, 21 patients aged 14–77 years, from 12 French hospitals. Median GHRH was 548 ng/l (270–9779)....

Study aim: Pituitary function evaluation in patients with traumatic brain injury (TBI).Subjects: One hundred and forty-six patients (49 female, 97 men, age: 31.9±16.2 years) recovered from moderate to severe TBI. Prospective follow up has been performed 3/6 and 12 months from TBI for 79 subjects. Retrospective evaluation (from 0.3 to 30 years) included 67 subjects selected in front of overt clinical features (obesity, fatigue, sexual disorders)....
