The Role of Modern Radiological Procedures in Diagnosing Blunt Liver Injuries Manifested by Upper Gastrointestinal Bleeding.

Posttraumatic upper gastrointestinal bleeding (UGIB) is a very rare consequence of blunt liver trauma. It can be quite a diagnostic challenge for clinicians, as it can clinically manifest many weeks after the trauma or be scantily symptomatic. The following article would like to provide an analysis of clinical cases of 13 patients following blunt liver injuries, the main symptoms of which was bleeding into the gastrointestinal tract through the biliary tree.

Undisclosed facts in Friedrich Wegener's links with Nazism.

Friedrich Wegener was the author of a comprehensive description of a disease that was named Wegener's granulomatosis. In 2010, its name was changed to granulomatosis with polyangiitis (GPA), the reason being that Wegener's links to Nazism were revealed. The research was conducted between May 2021 and August 2023 and was based on the historical method (understood as defining the subject of research, critical analysis of collected historical source materials, and historiographical synthesis) using the methods of direct and indirect inference ascribed to the historical method.

Rupture of an accessory spleen caused by blunt trauma.

Purpose: The accessory spleen is quite a common abdominal anomaly. However, the traumatic accessory spleen rupture is an extremely rare condition requiring surgical intervention, even laparotomy. 9 cases of traumatic accessory spleen were found published between 1962 and 2022.

Meckel's Diverticulum Injuries after Blunt Trauma.

: The complications associated with Meckel's diverticulum (MD) are well-known. However, blunt injuries regarding MD have not been widely described in the literature. This was the reason for undertaking research on MD lesions.

Carboxymethyl Chitosan Hydrogels for Effective Wound Healing-An Animal Study.

Hydrogels have various applications in medicine, for example, in systems for controlled drug release or as wound dressings, where they provide an appropriate environment for healing and constitute a barrier to microorganisms. The aim of this study was to evaluate the action of carboxymethyl chitosan (CMCS) hydrogels in wound healing therapy in vivo using a laboratory rat model. The hydrogels were formed from aqueous solutions of a CMCS biopolymer via electron beam irradiation, with the presence of a crosslinking agent of poly(ethylene glycol) diacrylate.
