Familial isolated pituitary adenomas (FIPA) and the pituitary adenoma predisposition due to mutations in the aryl hydrocarbon receptor interacting protein (AIP) gene.

Endocrine reviews, 2013
Pituitary adenomas are one of the most frequent intracranial tumors and occur with a prevalence of approximately 1:1000 in the developed world. Pituitary adenomas have a serious disease burden, and their management involves neurosurgery, biological ...

Clinical characteristics and temporal trends of lumbar drain use in minimally invasive resection of pituitary neoplasms

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
Abstract Objectives Appropriate scenarios of lumbar drain (LD) use in endonasal skull base surgery is an active area of investigation. However, existing data is limited. The purpose of this study is to evaluate the robustness of the NSQIP database to characterize morbidity and complications associated with LD usage concurrent to minimally invasive ...

Identification of Differentially Expressed Genes in Pituitary Adenomas by Integrating Analysis of Microarray Data

International Journal of Endocrinology, 2015
Pituitary adenomas, monoclonal in origin, are the most common intracranial neoplasms. Altered gene expression as well as somatic mutations is detected frequently in pituitary adenomas.

Template-Cut: A Pattern-Based Segmentation Paradigm [PDF]

, 2012
We present a scale-invariant, template-based segmentation paradigm that sets up a graph and performs a graph cut to separate an object from the background. Typically graph-based schemes distribute the nodes of the graph uniformly and equidistantly on the

TransResU-Net: Transformer based ResU-Net for Real-Time Colonoscopy Polyp Segmentation [PDF]

arXiv, 2022
Colorectal cancer (CRC) is one of the most common causes of cancer and cancer-related mortality worldwide. Performing colon cancer screening in a timely fashion is the key to early detection. Colonoscopy is the primary modality used to diagnose colon cancer.

Familial SDHA mutation associated with pituitary adenoma and pheochromocytoma/paraganglioma.

Journal of Clinical Endocrinology and Metabolism, 2013
CONTEXT Reports of the coexistence of pituitary adenomas and pheochromocytoma/paraganglioma are uncommon. Recently germline mutations in 2 of the genes encoding succinate dehydrogenase, SDHC and SDHD, were associated with pituitary tumors.

Pituitary adenoma management and outcomes according to hospital case volume and facility type

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
Abstract Objectives This study evaluates the influence of facility volume and type on the treatment and outcomes of pituitary adenoma (PA). Methods The 2004–2016 National Cancer Database was queried for patients with PA receiving definitive treatment. Tumor size represented the largest diameter of the primary tumor.

Stability and Hopf bifurcation analysis for the hypothalamic-pituitary-adrenal axis model with memory [PDF]

, 2016
This paper generalizes the existing minimal model of the hypothalamic-pituitary-adrenal (HPA) axis in a realistic way, by including memory terms: distributed time delays, on one hand and fractional-order derivatives, on the other hand. The existence of a unique equilibrium point of the mathematical models is proved and a local stability analysis is ...

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

Andrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Loss-of-function mutations in the CABLES1 gene are a novel cause of Cushing's disease. [PDF]

, 2017
The CABLES1 cell cycle regulator participates in the adrenal-pituitary negative feedback, and its expression is reduced in corticotropinomas, pituitary tumors with a largely unexplained genetic basis.
