2. Non-functioning pituitary adenomas and pregnancy: one-center experience and review of the literature
SUMMARY The usual clinical presentation of non-functioning pituitary adenoma (NFPA) consists of symptoms of mass effect and hypopituitarism. NFPA is a rare condition in young women and an uncommon complication during pregnancy. We present the outcome of three patients with NFPA during pregnancy. Case 1: a 38-year-old woman was referred at 32nd week of sponta

6. A review of Cushing's disease treatment by the Department of Neuroendocrinology of the Brazilian Society of Endocrinology and Metabolism
ABSTRACT The treatment objectives for a patient with Cushing's disease (CD) are remission of hypercortisolism, adequate management of co-morbidities, restoration of the hypothalamic-pituitary-adrenal axis, preservation of fertility and pituitary function, and improvement of visual defects in cases of macroadenomas with suprasellar extension. Transsphenoidal

7. Expression of E-cadherin, Slug and NCAM and its relationship to tumor invasiveness in patients with acromegaly
Pituitary adenomas account for 10–15% of primary intracranial tumors. Growth hormone (GH)-secreting adenomas account for 13% of all pituitary adenomas and cause acromegaly. These tumors can be aggressive, invade surrounding structures and are highly recurrent. The objective of this study was to evaluate E-cadherin, Slug and neural cell adhesion molecule (N

8. Pituitary apoplexy: pathophysiology, diagnosis and management
Pituitary apoplexy is characterized by sudden increase in pituitary gland volume secondary to ischemia and/or necrosis, usually in a pituitary adenoma. Most cases occur during the 5th decade of life, predominantly in males and in previously unknown clinically non-functioning pituitary adenomas. There are some predisposing factors as arterial hypertension, an

9. Expressão dos genes relacionados à apoptose, Bcl-2, bax, e caspase-3 nos adenomas hipofisários clinicamente não funcionantes e seu potencial como marcador do comportamento tumoral / Bcl-2, bax and caspase-3 apoptosis related genes expression in nonfunctioning pituitary adenoma and their role as potential markers of tumor behavior
Pituitary adenomas are benign, slow-growing tumors that arise in the sella turcica and account for 10% to 15% of all intracranial tumors. Non-functioning pituitary adenomas (NFPA) account for around one third of all pituitary adenomas. NFPA do not clinically present as hormonal syndromes and are generally diagnosed as macroadenomas due to marked neurological

10. Papel da via lkaros-FGFR4 na evolução pós-cirúrgica dos pacientes com doença de Cushing / Ikaros-FGFR4 pathway: role in the postoperative outcome of Cushings disease
Introduction: The mechanisms involved in the molecular pathogenesis of corticotroph pituitary tumors are complex, heterogeneous and in most cases remain unknown. Changes in the expression of components of Ikaros (Ik) pathway, such as receptor 4 of fibroblast growth factor (FGFR4), have been detected in pituitary tumors including corticotropinomas. Imbalance

11. Analysis of postoperative findings on dynamic magnetic resonance imaging of patients operated for pituitary tumors by transsfenoidal endonasal approach / Estudo das alterações em exames de ressonância magnética de pacientes em pós-operatório imediato de ressecção de tumores hipofisários por via transesfenoidal
Exames pós-operatórios de cirurgias intracranianas são difíceis de serem interpretados por apresentarem alterações morfológicas que simulam situações patológicas, como edema e tumores residuais. Com o advento de métodos de ressonância intraoperatória essa interpretação ganhou maior importância, pelo risco de re-intervenções desnecessárias.

12. Cushing's disease today. Late follow-up of 17 adrenalectomy patients with emphasis on eight with adrenal autotransplants.
Cushing's disease has come full cycle. As originally asserted more than 50 years ago, modern diagnostic techniques now demonstrate an adrenocorticotropic hormone (ACTH) secreting pituitary adenoma in approximately 80% of such patients. At this historical juncture, we report a long-term follow-up of our 17 patients who underwent adrenalectomy (8) or later adr
