Background: Over 90% of pancreatic stones are radiopaque and can be treated with endoscopy or surgery. However, radiolucent stones are different than radiopaque stones in nature and formation, and therefore, treatment varies. A 25-year-old woman was admitted because of recurrent acute pancreatitis. Imaging examinations confirmed the diagnosis of chronic pancreatitis (CP), and which revealed the existence of radiolucent stones. Endoscopic retrograde cholangiopancreatography (ERCP) was performed and abundant protein-like radiolucent stones were extracted. Three 10F, 7-cm plastic stents were placed. However, the stents were completely occluded by radiolucent stones 1 month later. A nasopancreatic tube was then inserted and flushed regularly, but protein-like stones formed continuously. After multidisciplinary consultation, the following conservative treatment strategy was applied: 1) no more endotherapy; 2) a diet with 40% to 50% of calories from fat was recommended; 3) no pancreatic enzyme replacement therapy; and 4) regular exercise. The above advice aimed to stimulate the secretion of pancreatic fluid to achieve auto-flushing of the pancreatic duct and prevent protein-like stones from depositing. No acute pancreatitis recurred during the 5-year follow-up.
Conclusions: This strategy was effective for auto-flushing the pancreatic duct in patients with radiolucent pancreatic stones after the main pancreatic duct stricture was resolved.

Influence of orthodontic bracket block-out materials on superimposition errors when substituting scanned dental imaging data onto computed tomography images.
Imaging Sci Dent

Department of Oral and Maxillofacial Surgery, College of Dentistry, Yonsei University, Seoul, Korea.
Purpose: The study was performed to examine the error associated with image superimposition when computed tomography (CT) images of the dental region are substituted with dental scan data, according to the block-out material used in dental impressions.
Materials And Methods: A typodont model was created by bonding orthodontic brackets to teeth on plaster dental stones using melted dental base-plate wax. In the experiment, 2 groups were compared: one using wax and the other using putty as the block-out material to prevent tearing of the impression material during the acquisition of dental impressions.
A comparative study of postadrenalectomy hyperuricemia and renal impairment in patients with unilateral primary aldosteronism: does histopathology subtype matter?

Article Synopsis
- Primary aldosteronism (PA) affects 5-18% of hypertensive patients and can be treated effectively with adrenalectomy, especially for those with unilateral PA.
- A cohort study of 100 patients post-adrenalectomy found that classical PA patients showed higher rates of elevated serum uric acid (SUA) and significant reductions in estimated glomerular filtration rate (eGFR) compared to nonclassical patients.
- The findings suggest that those with classical PA experience more complications like post-adrenalectomy hyperuricemia (PAHU) and decreased vessel stiffness, highlighting the need for ongoing monitoring of uric acid and kidney function post-surgery.

Comparative study between retrograde intrarenal surgery and ultrasound- guided shock wave lithotripsy for treatment of 1 to 2 cm radiolucent lower calyceal stones.
Urol Ann

Department of Urology, Faculty of Medicine, Benha University, Benha, Egypt.
Objectives: The objective is to compare the safety and efficacy of retrograde intrarenal surgery (RIRS) and ultrasound-guided (US-guided) shock wave lithotripsy (SWL) for the treatment of radiolucent lower pole calculi of 1-2 cm.
Materials And Methods: This prospective randomized study was performed at our tertiary care urology institute of Benha University Hospitals; cases were randomized either to undergo RIRS (Group A) or US-guided SWL with a triple focus system (Group B). The safety and effectiveness of both therapies were compared using new criteria for stone-free rate (SFR): Grade A (absolutely stone free), Grade B (≤2 mm fragments), and Grade C (>2 mm up to 4 mm fragments), fluoroscopy time, operative time, auxiliary procedures, retreatment, and complications.
What are the clues to gallstone ileus when stones don't show up on scans? A case presentation and literature review.

Article Synopsis
- - Gallstone ileus is a rare cause of bowel obstruction in older adults, resulting from gallstones moving into the intestines through a fistula due to chronic inflammation.
- - Symptoms like nausea, vomiting, and abdominal pain can delay diagnosis, making advanced imaging, especially CT scans, important for identifying the condition.
- - Prompt surgical intervention, typically via enterolithotomy, is crucial for treatment; other procedures may be required based on the patient's condition, emphasizing the need for early recognition to improve outcomes.
