Genetic background influences tumour development in heterozygous Men1 knockout mice [PDF]

, 2020
Multiple endocrine neoplasia type 1 (MEN1), an autosomal dominant disorder caused by MEN1 germline mutations, is characterised by parathyroid, pancreatic and pituitary tumours. MEN1 mutations also cause familial isolated primary hyperparathyroidism (FIHP)

Treatment of Aggressive Pituitary Adenomas: A Case-Based Narrative Review

Frontiers in Endocrinology, 2021
Management of aggressive pituitary adenomas is challenging due to a paucity of rigorous evidence supporting available treatment approaches. Recent guidelines emphasize the need to maximize standard therapies as well as the use of temozolomide and ...

Pituitary calcification masquerading as pituitary apoplexy

Indian Journal of Endocrinology and Metabolism, 2013
Pituitary calcification occurs commonly in lactotroph or somatotroph adenoma but rare in chomophobe or gonadotroph adenoma. On imaging, it can mimic hemorrhage, hence may masquerade pituitary apoplexy if patient present with neurological manifestations. We present a case of pituitary calcification which mimicked pituitary apoplexy.

Does an Analysis of the Pulsatile Secretion Pattern of Adrenocorticotropin and Cortisol Predict the Result of Transsphenoidal Surgery in Cushing’s Disease. [PDF]

, 1993
The endocrinological, surgical, and histological findings of patients with ACTH-dependent Cushing's disease were correlated with the pulsatile secretion pattern of ACTH and cortisol and the outcome after transsphenoidal pituitary surgery.

The Clinical and Pathological Characteristics of Refractory Pituitary Adenomas: A Single Center Experience

Frontiers in Oncology, 2022
BackgroundMost of pituitary adenomas (PAs) are slow-growing benign tumors which can be cured or controlled by conventional therapies, including surgery, medical treatment or radiotherapy.

IgG4-Related Inflammatory Pseudotumor Involving the Clivus: A Case Report and Literature Review

Frontiers in Endocrinology, 2021
IgG4-related inflammatory pseudotumors are very uncommon and are characterized histologically by the presence of inflammatory swellings with increasing IgG4-positive plasma cells and lymphocytes infiltrating the tissues.

Mechanisms for pituitary tumorigenesis: the plastic pituitary [PDF]

Journal of Clinical Investigation, 2003
The anterior pituitary gland integrates the repertoire of hormonal signals controlling thyroid, adrenal, reproductive, and growth functions. The gland responds to complex central and peripheral signals by trophic hormone secretion and by undergoing reversible plastic changes in cell growth leading to hyperplasia, involution, or benign adenomas arising ...

Preoperative Fasting C-Peptide Acts as a Promising Predictor of Improved Glucose Tolerance in Patients With Acromegaly After Transsphenoidal Surgery: A Retrospective Study of 64 Cases From a Large Pituitary Center in China

Frontiers in Endocrinology, 2019
Purpose: Abnormal glucose metabolism is one of the most frequent acromegaly complications. Improvement of glucose metabolism can be observed only in half of acromegaly patients after surgery.

Prediction of the Recurrence of Non-Functioning Pituitary Adenomas Using Preoperative Supra-Intra Sellar Volume and Tumor-Carotid Distance

Frontiers in Endocrinology, 2021
BackgroundCurrently, it is difficult to estimate the possibility of recurrence of nonfunctioning pituitary adenomas (NFPAs). Markers such as Ki-67 or transcription factors rely on postoperative pathology, while few indices can be used for preoperative ...

Pesticide Exposure Alters Follicle-Stimulating Hormone Levels in Mexican Agricultural Workers [PDF]

, 2005
Organophosphorous pesticides (OPs) are suspected of altering reproductive function by reducing brain acetylcholinesterase activity and monoamine levels, thus impairing hypothalamic and/or pituitary endocrine functions and gonadal processes. Our objective
