Pancreatic Neuroendocrine Tumor Leading to a Diagnosis of Multiple Endocrine Neoplasia Type 1

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Pancreatic neuroendocrine neoplasms are rare but occasionally encountered. They are generally highly vascularized solid tumors, often round in shape with clear boundaries, defined contours, and a homogeneous internal structure. However, they can also present with atypical features, such as cystic degeneration, hemorrhage, calcification, and ...

Short-term outcome of endoscopic versus microscopic pituitary adenoma surgery: a systematic review and meta-analysis

open access: yesJournal of Neurology Neurosurgery & Psychiatry, 2012
Endoscopic transsphenoidal pituitary surgery has become increasingly more popular for the removal of pituitary adenomas. It is also widely recognised that transsphenoidal microscopic removal of pituitary adenomas is a well-established procedure with good

Improving Operator Depth Vision in Gastrointestinal Endoscopy: A Pilot Study of a New Three‐dimensional Imaging System

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background and aims Traditional two‐dimensional (2D) gastrointestinal endoscopy lacks depth perception, leading to potential diagnostic errors. This study evaluates a novel software‐based three‐dimensional (3D) endoscopy system that converts 2D images into 3D, compatible with existing endoscopes.

Cohesins: Crossroad Between Cornelia de Lange Spectrum and Cancer Predisposition

open access: yesAmerican Journal of Medical Genetics Part A, Volume 197, Issue 8, August 2025.
ABSTRACT The cohesin complex plays crucial roles in DNA repair, chromatid separation, and gene transcription regulation. Pathogenic variants in cohesins or dysfunctional transcriptional regulators lead to cohesinopathies, a broader group of disorders including Cornelia de Lange Spectrum (CdLSp), for which the prevalence of cancer cases remains unclear.

Patient Participation in Urine Specific Gravity Screening for Arginine Vasopressin Deficiency in an Inpatient Neurosurgical Clinic

open access: yesClinical Endocrinology, Volume 103, Issue 2, Page 201-208, August 2025.
ABSTRACT Objective Detecting hypotonic urine (specific gravity < 1005 g/L) is crucial for the early identification of arginine vasopressin deficiency (AVP‐deficiency), a common complication after pituitary surgery. This study aimed to evaluate the agreement between urine specific gravity measurements taken by patients using urine test strips and those ...

An autocrine role for pituitary GABA: Activation of GABA-B receptors and regulation of growth hormone levels [PDF]

open access: yes, 2002
There is increasing evidence suggesting that the neurotransmitter gamma-aminobutyric acid (GABA) is a local factor involved in the regulation of endocrine organs.
