Diagnostic Value of Endoscopic Ultrasound‐Guided Tissue Acquisition With Rapid On‐Site Evaluation in Small Gastric Subepithelial Lesions

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Gastric subepithelial lesions (SELs) measuring <20 mm without high‐risk features are typically managed with periodic surveillance, while surgical resection is recommended for gastrointestinal stromal tumors (GISTs) per the Japanese guideline.

Deep Learning‐Based Inner Ear Subregion Segmentation in 3D T2‐Weighted MRI Using Label‐Preserving Data Augmentation

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
A deep learning segmentation model was proposed for automated inner ear subregion segmentation using 3D T2‐weighted MRI. A transformer‐based model with label‐preserving data augmentation improves delineation of thin and complex structures such as the semicircular canals.

Impact of tissue staining and scanner variation on the performance of pathology foundation models: a study of sarcomas and their mimics

The Journal of Pathology: Clinical Research, Volume 12, Issue 2, March 2026.
Abstract Histopathological analysis is considered the gold standard for the diagnosis and prognostication of cancer. Recent advances in AI, driven by large‐scale digitisation and pan‐cancer foundation models, are opening new opportunities for clinical integration.

Presacral schwannoma

Journal of Visceral Surgery, 2012
Presacral schwannoma is a rare tumor, diagnosed essentially by pelvi-rectal digital examination. Diagnostic investigations should include initial CT-scan followed by pelvic MRI. The role of angiography and preoperative biopsy remain debated. Management is surgical: several surgical routes are possible to remove the tumor; resection essentially consists

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, Volume 200, Issue 3, Page 661-672, March 2026.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...
