Case Report: Carcinoma Ex-Pleomorphic Adenoma With Concurrent Submandibular Gland Lithiasis-A Rare Association With Potential Pathophysiological Implications. [PDF]

Clin Case Rep
ABSTRACT This case report details the exceptionally rare co‐occurrence of submandibular gland lithiasis and carcinoma ex‐pleomorphic adenoma (CXPA), representing only the fourth documented instance worldwide. The patient, a 79‐year‐old male with a 10‐year history of recurrent submandibular symptoms, was found to have both ductal and intraglandular ...

Efficacy and Tolerability of Transoral Sialolithotomy in Non-Palpable Submandibular Lithiasis. [PDF]

Laryngoscope
Transoral sialolithotomy has long been considered inappropriate for non‐palpable submandibular stones. In this retrospective cohort of 457 patients, we compared outcomes between palpable and non‐palpable stones, showing that the technique allows successful removal in 87% of non‐palpable cases, with no associated complications.

Selection criteria for preoperative endoscopic retrograde cholangiopancreatography before laparoscopic cholecystectomy and endoscopic treatment of bile duct stones. Results of a retrospective; single center study between 1996-2002 [PDF]

, 2004
AIM: The optimal treatment for bile duct stones (in terms of cost, complications and accuracy) is unclear. The aim of our study was to determine the predictive factors for preoperative endoscopic retrograde cholangiopancreatography (ERCP).

Carboxymethylated Rhizoma alismatis Polysaccharides Regulate Calcium Oxalate Crystals Growth and Reduce the Regulated Crystals’ Cytotoxicity

Biomolecules, 2023
Objective: This study explored the effects of polysaccharides (RAPD) extracted from the traditional anti-stone Chinese medicine Rhizoma alismatis and their carboxymethylated derivatives (RAPs) on the crystal phase, morphology, and size of calcium oxalate

Effect of sample time on urinary lithogenic risk indexes in healthy and stone-forming adults and children

BMC Urology, 2018
Background The diagnosis and follow-up of stone forming patients is usually performed by analysis of 24-h urine samples. However, crystallization risk varies throughout the day, being higher at night.

Phytate Dephosphorylation Products Also Act as Potent Inhibitors of Calcium Oxalate Crystallization

Molecules, 2022
Phytate has been classified as an anti-nutrient, but there are no adverse effects from the consumption of a balanced diet with 1 to 2 g of daily phytate (inositol-hexaphosphate, InsP6) as a calcium magnesium salt, the form naturally present in grains ...
