Indocyanine green fluorescence‐guided sentinel lymph node biopsy: A systematic review

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 11, Issue 2, Page 298-307, June 2025.
Abstract Objectives Accurate staging of cervical lymph nodes is crucial in the management of head and neck cancers (HNCs). Sentinel lymph node biopsy (SLNB) offers a minimally invasive alternative to neck dissection for identifying occult metastases. This review aims to assess the feasibility and effectiveness of indocyanine green (ICG) fluorescence ...

Efficacy of Urine Asymmetric Dimethylarginine Concentration to Predict Azotemia in Hyperthyroid Cats After Radio‐Iodine Treatment

Journal of Veterinary Internal Medicine, Volume 39, Issue 3, May/June 2025.
ABSTRACT Background Hyperthyroidism can mask concurrent chronic kidney disease in cats, and no accurate biomarkers are available to predict which cats will develop renal azotemia after radioiodine (131I) treatment. Hypothesis/Objectives To evaluate the potential of serum and urinary metabolites and metabolite ratios to predict post‐131I renal azotemia ...
