Methodology of high‐dimensional flow cytometry in monitoring immune microenvironment of pituitary neuroendocrine tumors

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Characterization of the tumor immune microenvironment (TIME) of pituitary neuroendocrine tumors (PitNETs) is crucial for understanding the behavior of different types of PitNETs and identification of possible causes of their aggressiveness, rapid growth, and resistance to therapy.

Pituitary Adenomas

Topics in Magnetic Resonance Imaging, 2005
Pituitary adenomas are by far the most common sellar tumor and magnetic resonance imaging is the modality of choice for their detection and characterization. However, most of these neoplasms are asymptomatic and frequently incidentally visualized.

Evidence‐based management strategies for endocrine complications after pituitary adenoma surgery

Ibrain, EarlyView.
Based on the PIPOST (Population, Intervention, Professional, Outcome, Setting, and Type of Evidence) framework, evidence‐based medicine questions were developed, and a top‐down search was conducted according to the 6S model of the evidence pyramid. The literature sources were best practices, guidelines, expert consensuses, systematic reviews, meta ...

A unique coexistence of a plurihormonal pituitary adenoma with granulomatous hypophysitis

Indian Journal of Pathology and Microbiology, 2023
Dual pathology in the pituitary gland is a unique phenomenon. Coexistence of a pituitary adenoma with primary hypophysitis has been reported rarely with very few cases in the literature.

Brain tumor detection using artificial convolutional neural networks [PDF]

arXiv, 2022
In this paper, a convolutional neural network (CNN) was used to classify NMR images of human brains with 4 different types of tumors: meningioma, glioma and pituitary gland tumors. During the training phase of this project, an accuracy of 100% was obtained, meanwhile, in the evaluation phase the precision was 96%.

Pituitary apoplexy: re-evaluation of risk factors for bleeding into pituitary adenomas and impact on outcome [PDF]

, 2011
Objective: To assess frequency, symptoms and outcome of pituitary apoplexy (PA) among pituitary adenoma patients, to gain better insight into risk factors for bleeding into pituitary adenoma, and to estimate the sequelae of PA by means of a matched ...

Heterogeneous Genetic Background of the Association of Pheochromocytoma/Paraganglioma and Pituitary Adenoma: Results From a Large Patient Cohort

Journal of Clinical Endocrinology and Metabolism, 2014
Context: Pituitary adenomas and pheochromocytomas/paragangliomas (pheo/PGL) can occur in the same patient or in the same family. Coexistence of the two diseases could be due to either a common pathogenic mechanism or a coincidence.

Analysis of the experimental absorption spectrum of the rabbit lung and identification of its components

Journal of Biophotonics, EarlyView.
The broadband absorption coefficient spectrum of the rabbit lung was reconstructed from the absorption spectra of tissue components. The similar accumulation of melanin and lipofuscin was retrieved from the broadband baseline in the absorption coefficient spectrum, and the calculation of the absorption fold ratios for proteins, DNA and hemoglobin ...

Genetics of Pituitary Adenomas [PDF]

, 2013
Pituitary adenomas are common tumors of the adenohypophysis which can cause considerable morbidity, due to excessive hormonal secretion or compression and local invasion of surrounding structures. The vast majority of pituitary adenomas occur sporadically.

Symptomatic narcolepsy in a dog with functional pituitary gland macroadenoma

Veterinary Record Case Reports, EarlyView.
Abstract Symptomatic narcolepsy in dogs has been rarely reported. A 7‐year‐old, female, neutered Greek harehound presented with chronic progressive lethargy, dysphonia, episodes of flaccid paralysis of all limbs following excitement or eating, as well as pinnae and tail alopecia, hyperpigmentation and ‘rat tail’.
