Cushing's syndrome

Objective: The aim was to formulate practice guidelines for the diagnosis and treatment of hyperprolactinemia. Participants: The Task Force consisted of Endocrine Society-appointed experts, a methodologist, and a medical writer. Evidence: This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe both the strength of recommendations and the quality of evidence. Consensus Process: One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of The Endocrine Society, The European Society of Endocrinology, and The Pituitary Society reviewed and commented on preliminary drafts of these guidelines. Conclusions: Practice guidelines are presented for diagnosis and treatment of patients with elevated prolactin levels. These include evidence-based approaches to assessing the cause of hyperprolactinemia, treating drug-induced hyperprolactinemia, and managing prolactinomas in nonpregnant and pregnant subjects. Indications and side effects of therapeutic agents for treating prolactinomas are also presented. (J Clin Endocrinol Metab 96: 273–288, 2011)

Diagnosis and treatment of hyperprolactinemia: an Endocrine Society clinical practice guideline

Mood disorders and allostatic load.

Objective: The aim was to provide guidelines for evaluation, treatment, and genetic testing for multiple endocrine neoplasia type 1 (MEN1). Participants: The group, which comprised 10 experts, including physicians, surgeons, and geneticists from international centers, received no corporate funding or remuneration. Process: Guidelines were developed by reviews of peer-reviewed publications; a draft was prepared, reviewed, and rigorously revised at several stages; and agreed-upon revisions were incorporated. Conclusions: MEN1 is an autosomal dominant disorder that is due to mutations in the tumor suppressor gene MEN1, which encodes a 610-amino acid protein, menin. Thus, the finding of MEN1 in a patient has important implications for family members because first-degree relatives have a 50% risk of developing the disease and can often be identified by MEN1 mutational analysis. MEN1 is characterized by the occurrence of parathyroid, pancreatic islet, and anterior pituitary tumors. Some patients may also develo...

Clinical practice guidelines for multiple endocrine neoplasia type 1 (MEN1)

OBJECTIVE:The primary objectives of this report were, first, to determine the number and incidence of complications of transsphenoidal surgery performed by a cross-section of neurosurgeons in the United States and, second, to ascertain the influence of the surgeon's experience with the procedure on

Complications of Transsphenoidal Surgery: Results of a National Survey, Review of the Literature, and Personal Experience

We have examined the serum growth hormone (GH) and prolactin (PRL) response to growth hormone releasing factor (hGRF-(1-44)NH2 (GRF) 1 microgram/kg i.v. bolus) in 16 acromegalic patients (eight of whom were hyperprolactinaemic), 13 patients with microprolactinoma, and 14 healthy subjects. The GH responses to TRH and to the somatostatin analogue SMS 201-995 were also studied in acromegalic patients. In these, and in patients with microprolactinoma, GH responses after GRF (P less than 0.001 vs saline) were variable. The absolute GH increase (calculated as area under the curve) in acromegalic patients (2489 +/- 920 micrograms/l min), or in patients with microprolactinoma (1322 +/- 279 micrograms/l min) was not different from that in controls (2238 +/- 633 micrograms/l min). In addition, a significant increase in PRL release was observed after GRF in comparison to saline in acromegalic patients (P less than 0.01), in patients with microprolactinoma and in normal subjects (P less than 0.001). The PRL increase was significantly correlated with basal PRL levels in acromegalic patients (r = 0.99, P less than 0.001) and in patients with microprolactinomas (r = 0.61, P less than 0.05). Furthermore, a significant correlation was found between GH rise after GRF and basal GH, and between GH rise after GRF and GH decrement after SMS in patients with acromegaly. These results suggest that GRF can stimulate PRL release by actions on the normal pituitary and on pituitary adenomas, including microprolactinomas. Moreover, the data suggest that in acromegaly there is a relative functional deficiency of hypothalamic somatostatin.

Le traitement de l'acromégalie

Acromegaly is a rare disease which can significantly reduce life expectancy. Clinical features are diverse and the patient may consult a variety of medical and surgical specialists before the diagnosis is suspected. However, the disease is easily confirmed by the appropriate laboratory tests, namely GH and IGF1 measurements. In most cases, acromegaly is secondary to a micro or macrosomatotrope pituitary adenoma. Those lesions are easily visualized by a pituitary CT Scan or Magnetic Resonance Imaging. Visual fields have to be evaluated by a neuro-ophthalmologist, and a thorough evaluation of other pituitary functions have to be performed. Selective removal of the adenoma by the transsphenoidal route is the treatment of choice for acromegaly. When performed by an experienced neurosurgeon, normalization of GH secretion can be expected in approximately 75% of cases. The surgical outcome is modulated by the volume, the extension of the tumor and the preoperative GH level. Octreotide, radiotherapy or bromocriptine are indicated whenever the patient remains with an elevated level of GH with persistency of symptoms.
