A rare cause of recurrent spontaneous pneumothorax: Birt-hogg-dube syndrome [PDF]
, 2018 Birt-Hogg-Dube (BHD) syndrome is an unusual disorder characterized by the triad of cutaneous lesions, renal tumors and lung cysts. In cases with BHD syndrome, the frequency of recurrent pneumothorax is increased due to presence of multiple lung cysts. It

Effect of miR-106b on Invasiveness of Pituitary Adenoma via PTEN-PI3K/AKT
Medical Science Monitor, 2017 Background Pituitary adenomas are mostly benign tumors, although certain cases have invasiveness, which might be related with high expression of miR-106b. The PTEN-PI3K/AKT signal pathway is known to be related with cell migration and invasion.

Effects of loperamide on the human hypothalamo-pituitary-adrenal axis in vivo and in vitro. [PDF]
, 1992 Loperamide, an opiate agonist of high specificity for p-receptors, was recently reported to suppress ACTH and cortisol levels in normal subjects, but not in patients with proven ACTH-dependent Cushing’s disease. However, there is little information on

Identification and gene expression profiling of human gonadotrophic pituitary adenoma stem cells
Acta Neuropathologica Communications, 2023 Background Gonadotrophic pituitary adenoma is a major subtype of pituitary adenoma in the sellar region, but it is rarely involved in the hypersecretion of hormones into blood; thus, it is commonly regarded as “non-functioning.” Its tumorigenic ...

Refractory pituitary adenoma: a novel classification for pituitary tumors
OncoTarget, 2016 Pituitary adenomas are classified as typical or atypical, invasive or noninvasive, and aggressive or nonaggressive based on pathological features, radiological findings, and clinical behavior.

The Genetics of Pituitary Adenomas [PDF]
, 2011 Cancer is considered a disease of the genome since the development of the vast majority of the human neoplasias is due to the accumulation of gene mutations. Indeed, the vast majority of tumours occur due to a considerable number of mutations that human cells accumulate during lifetime. Approximately 380 genes, representing about 1% of all human genes,

Frontiers in Neurology, 2022 The coexistence of meningioma and pituitary adenoma is very rare, especially in the same location after meningioma surgery. Here, we reported a case of coexisting meningioma and pituitary adenoma secondary to postoperative meningioma in the sellar region
