Histological criteria for atypical pituitary adenomas – data from the German pituitary adenoma registry suggests modifications

open access: yesActa Neuropathologica Communications, 2015
The term atypical pituitary adenoma (APA) was revised in the 2004 World Health Organization (WHO) classification of pituitary tumors. However, two of the four parameters required for the diagnosis of APAs were formulated rather vaguely (i.e., “extensive”

A Novel International Endoscopic Sphenoid Surgery Classification (IESSC): A Delphi Consensus

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Advancements in endoscopic sinus and skull base surgery created a need for standardized terminology to describe sphenoid sinus surgery. Although classification systems exist for other sinuses, one for endoscopic sphenoid sinus surgery is lacking.

Mathematical Modelling of Hypothalamus-Pituitary-Adrenal Axis Dynamics: A Review, a Novel Approach, and Future [PDF]

open access: yesarXiv, 2023
A novel mathematical model for the hypothalamic pituitary adrenal (HPA) axis is proposed to comprehend the oscillations observed in hormone concentration and potential dysfunction within the HPA axis in stressful situation. This model integrates impact of hippocampal receptors on the secretion of corticotropin-releasing hormone (CRH), an additional ...

Long‐Term Particulate Matter Exposure May Increase Risk of Chronic Rhinosinusitis WIth Nasal Polyposis: Results from an Exposure‐Matched Study

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Particulate matter ⩽2.5 µm in diameter (PM2.5) and its role in chronic rhinosinusitis (CRS) pathogenesis have gained heightened attention. We previously demonstrated that PM2.5 exposure may bias the nasal mucosa in CRS toward a Type 2 inflammatory pathway.

Preservation of multidimensional quality of life after endoscopic pituitary adenoma resection.

open access: yesJournal of Neurosurgery, 2015
OBJECT Pituitary adenomas are well suited to resection by a minimal-access endoscopic technique. Validation of this approach requires prospective outcome studies to determine the impact on quality of life (QOL).

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

open access: yes, 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

Expert Strategies: Skull Base Reconstruction—Global Perspectives, Insights, and Algorithms through a Mixed Methods Approach

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Objective There is limited consensus on endoscopic skull base surgery (ESBS) reconstruction principles. This study aims to generate comprehensive themes regarding ESBS reconstruction by pooling the experiences of ESBS experts, with comparison to a literature review of current published evidence.
