Distal ileal volvulus leading to intestinal obstruction: A case report.
Int J Surg Case Rep
January 2025
Department of Diagnostic Radiology, BP Koirala Institute of Health Sciences (BPKIHS), Nepal.
Introduction: Small bowel volvulus (SBV) involves the abnormal twisting of a small bowel loop around its mesenteric axis, often causing intestinal obstruction. It is rare in Western countries but accounts for up to 20-35 % of small bowel obstruction (SBO) cases in Asia, Africa, and the Middle East due to dietary and environmental factors. Non specific symptoms might lead to delayed diagnosis.

Objective: The orthodontic mini-implant (OMI) failure often occurs due to the accumulation of peri-implantitis bacteria surrounding it, which results in a stable, resistant form of absolute skeletal anchorage during orthodontic treatment. Administering doxycycline may be the solution, but long-term side effects result in antibiotic resistance. Roselle flowers (Hibiscus sabdariffa) possess beneficial active phytochemical substances, which may have potential as an OMI peri-implantitis alternative therapy.

Radiation Safety and Quality Assurance division, National Cancer Center Hospital East, Chiba, 277-8577, Japan.
The impact of three-dimensional (3D) dose delivery accuracy of C-arm linacs on the planning target volume (PTV) margin was evaluated for non-coplanar intracranial stereotactic radiosurgery (SRS). A multi-institutional 3D starshot test using beams from seven directions was conducted at 22 clinics using Varian and Elekta linacs with X-ray CT-based polymer gel dosimeters. Variability in dose delivery accuracy was observed, with the distance between the imaging isocenter and each beam exceeding 1 mm at one institution for Varian and nine institutions for Elekta.

The clinical application of tyrosine kinase inhibitors (TKIs) is rapidly growing and has emerged as a cornerstone in the treatment of both solid tumors and hematologic malignancies. However, resistance to TKI targets and disease progression remain inevitable. Nanocarrier-mediated delivery has emerged as a promising strategy to overcome the limitations of the TKI application.

Purpose: Conventional brain MRI protocols are time-consuming, which can lead to patient discomfort and inefficiency in clinical settings. This study aims to assess the feasibility of using artificial intelligence-assisted compressed sensing (ACS) to reduce brain MRI scan time while maintaining image quality and diagnostic accuracy compared to a conventional imaging protocol.
Patients And Methods: Seventy patients from the department of neurology underwent brain MRI scans using both conventional and ACS protocols, including axial and sagittal T2-weighted fast spin-echo sequences and T2-fluid attenuated inversion recovery (FLAIR) sequence.
