Hernia is characterized by the protrusion of organs or tissue through weakened areas in the abdominal cavity wall. A common treatment for hernia involves the implantation of a mesh which promotes the growth of new tissue around or within the implanted material in the damaged area. The mesh is typically made from synthetic materials like polypropylene.

- - Total pelvic exenteration (TPE) is a complex surgical procedure that may be the sole curative option for patients with advanced rectal cancers, resulting in lifelong management of two permanent stomas.
- - There is a knowledge gap among radiologists regarding the complications that can arise after TPE surgery, leading to potential misdiagnosis or overlooked symptoms that could have serious consequences.
- - The article aims to enhance understanding of postoperative pelvic anatomy, highlight early and delayed complications, and provide guidance on imaging techniques to accurately diagnose issues related to TPE through illustrative case studies.
Background: Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration, caused by injury to the dentato-rubro-olivary pathway (DROP). Radiologically, this manifests as T2 hyperintensity, with or without enlargement of the inferior olivary nucleus. The purpose of the study was to evaluate the incidence, associated imaging characteristics, potential etiologies, latency period, and temporal progression of HOD in patients undergoing surgical resection of posterior fossa tumors (PFTs).

- * These tumors are located in critical areas of the brain and spinal cord, making surgical intervention difficult, and they typically present with a specific set of symptoms.
- * A case of a 17-year-old girl with spinal diffuse midline glioma showed unusual bone metastases, highlighting the need for early diagnosis and personalized treatment plans, as well as the importance of further research into the tumor's molecular characteristics.
Article Synopsis
- High-entropy alloys (HEAs), particularly nickel-based ones, are advanced materials known for their exceptional strength, ductility, and corrosion resistance, making them valuable in various applications.
- The review explores the principles of alloy design and the role of nickel, analyzing how composition and structure impact mechanical properties using concepts like valence electron concentration (VEC).
- It also highlights additive manufacturing (AM) techniques, examines their challenges (such as porosity and defects), and evaluates the effects of post-processing methods on the mechanical performance and oxidation behavior of nickel-based HEAs.
