An asymptomatic dissecting superior mesenteric artery (SMA) aneurysm in granulomatosis with polyangiitis (GPA), historically termed Wegener's granulomatosis, is rare. We herein describe a 68-year-old man who was diagnosed with GPA based on a high level of proteinase 3 (PR3)-antineutrophil cytoplasmic antibody (ANCA). One year after remission of GPA, the patient developed pyelonephritis, and his PR3-ANCA level increased again. Computed tomography showed a rapid increase in the size of the dissecting SMA aneurysm. The patient underwent successful endovascular stent-graft repair. At the time of this writing, 3 years had passed since the surgery and the clinical course was good.

This study describes the process of developing a high-impact, low-cost, and low-maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection tables. A creative-innovative construction methodology was used, combining the Theory of Inventive Problem Solving (TRIZ/TIPS) and VE for an anatomy laboratory air ventilation concept.

Introduction: Successful axillary reverse mapping (ARM) during lymph node surgery for breast cancer has the potential to reduce risk of lymphedema. Standard of care uses blue dye for ARM; however, recent imaging advances with near-infrared indocyanine green (ICG) fluorescence has demonstrated potential to improve intraoperative ARM imaging. The objective was to determine the feasibility of using ICG fluorescence through the OnLume Avata System for ARM.

Objective: To analyze the role of lymph node level ratio (LNLR) in predicting prognosis and the benefits of postoperative radiotherapy (PORT) in patients with pathological N1 (pN1) head and neck squamous cell carcinoma (HNSCC).
Methods: Patients with pN1 HNSCC from January 2011 to February 2021 were included. Patients were grouped by the LNLR, lymph node yield (LNY), and lymph node ratio (LNR) and were analyzed with the Kaplan-Meier method and multivariate Cox model.

The sustainable management of polydiene waste represents a formidable challenge in the realm of polymer chemistry, given the extensive industrial utilization of polydienes due to their superior elastomeric properties. This comprehensive Perspective addresses the multifaceted obstacles hindering efficient recycling of polydienes, encompassing environmental concerns, technical limitations, and economic disincentives. We systematically dissect the influence of polydienes' chemical structures on their recyclability, tracing the evolution of polydiene utilization and disposal practices while assessing the current landscape of waste management strategies.

Introduction: Laparoscopic distal pancreatectomy (LDP) has the advantages of reduced blood loss, shorter hospital stays, and a better postoperative quality of life compared with open distal pancreatectomy (ODP). Meanwhile, spleen-preserving laparoscopic distal pancreatectomy is the preferred technique for low-grade malignant and benign tumors located in pancreatic body and tail, since it preserves the immune function of the spleen. The splenic-vessel-preserving (SVP) Kimura technique and splenic vessel resection Warshaw technique are the two primary procedures.
