Numerous neurosurgical approaches are available for children presenting with hypothalamic hamartomas (HHs) associated with severe epilepsy. A concern regarding the impairment of short-term memory after resective surgery is promoting the exploration of less invasive alternatives like radiosurgery. Gamma knife radiosurgery (GKS) can lead to a real reversal of(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)
Bromocriptine or other dopamine agonists are usually effective for the treatment of prolactin-secreting adenomas. Five to 18% of prolactinomas, however, do not respond to such therapy. We have shown previously that such resistance to bromocriptine correlates with reduced binding to the D2 receptor subtype of dopamine, the major PRL inhibiting factor. In the(More)
Pituitary carcinomas are rare, accounting for about 0.2% of all pituitary tumours. They represent a challenge to clinical practice in both diagnosis and treatment. They may present initially as typical pituitary adenomas, with a delayed appearance of aggressive signs, or as aggressive tumours from the outset. Predicting the pituitary tumour behaviour(More)
OBJECTIVE Few data are published on the long-term follow-up of ipilimumab-induced hypophysitis, a cytotoxic T-lymphocyte antigen 4 antibody. We characterized hypophysitis in terms of clinical signs, endocrinological profile, and imaging at diagnosis and during a long-term follow-up. DESIGN AND PATIENTS Fifteen patients, treated for malignant melanoma and(More)
OBJECTIVE Though transsphenoidal surgery remains the first-line treatment of Cushing's disease, recurrence occurs frequently. Conventional radiotherapy and anticortisolic drugs both have adverse effects. Stereotactic radiosurgery needs to be evaluated more precisely. The aim of this study was to determine long-term hormonal effects and tolerance of gamma(More)
CONTEXT Although transsphenoidal surgery remains the first-line treatment in Cushing's disease (CD), recurrence is observed in about 20% of cases. Adjunctive treatments each have specific drawbacks. Despite its inhibitory effects on steroidogenesis, the antifungal drug ketoconazole was only evaluated in series with few patients and/or short-term follow-up.(More)
Several clinical studies reported the efficacy of the long-acting SRIH analog, octreotide (Octreotide, Sandoz) in the treatment of acromegaly. Recently, another SRIH analog (BIM 23014, Ipsen Biotech) was shown to decrease plasma GH levels in acromegalic patients. The recent availability of a long-acting formulation of BIM 23014 [slow release (SR)(More)
Among 288 patients with prolactinoma (aged 12-62 years; 242 women), 27 were diagnosed as resistant to bromocriptine as their plasma prolactin (PRL) levels remained elevated despite long-term (3 months or more) treatment at high doses (> or = 15 mg daily). These 18 women and 9 men, aged 29 +/- 9 years (mean +/- SD, range 13-50), followed-up for 8 +/- 4(More)
OBJECTIVE Mifepristone is the only available glucocorticoid receptor antagonist. Only few adult patients with hypercortisolism were treated to date by this drug. Our objective was to determine effectiveness and tolerability of mifepristone in Cushing's syndrome (CS). DESIGN Retrospective study of patients treated in seven European centers. METHODS(More)
