Background And Aim: Large-volume endoscopic injection of epinephrine has been proven to significantly reduce rates of recurrent peptic ulcer bleeding. Injection of normal saline may be equally effective for the similar hemostatic effect of local tamponade. The aim of our study was to compare the therapeutic effects of large-volume (40 mL) endoscopic injections of epinephrine, normal saline and a combination of the two in patients with active bleeding ulcers.
Method: A total of 216 patients with actively bleeding ulcers (spurting or oozing) were randomly assigned to three groups (1:10,000 epinephrine, normal saline or diluted epinephrine plus normal saline). The hemostatic effects and clinical outcomes were compared between the three groups.
Results: The initial hemostatic rate was significantly lower in the normal saline group (P < 0.05). The volume of injected solution required for the arrest of bleeding was significantly larger in the normal saline group (P < 0.01). Mean duration for arrest of bleeding was significantly longer in the normal saline group (P < 0.01). There were no significant differences between the three groups with respect to the rates of recurrent bleeding, surgical intervention, 30-day mortality, amount of transfusion and duration of hospitalization. Significant elevation of systolic blood pressure (P < 0.05) and persistent high pulse rate after endoscopic injection were observed in the epinephrine group.
Conclusions: For patients with active bleeding ulcers (spurting or oozing), we recommend a large-volume (40 mL) combination injection using diluted epinephrine to cease bleeding, followed by injection of normal saline to achieve sustained hemostasis.

Oxytocin ameliorates lipopolysaccharide-induced acute orchitis model: interplay of oxidative stress and inflammatory pathways.
Front Pharmacol

Department of Basic Medical Sciences, College of Medicine, AlMaarefa University, Riyadh, Saudi Arabia.
Introduction: Lipopolysaccharide (LPS), a constituent of the outer membrane of Gram-negative bacteria, is a powerful inducer of systemic inflammation and has been extensively utilized in experimental models to simulate inflammatory responses and septic disorders. Recent research indicates that oxytocin (OXY), a neuropeptide typically linked to social bonding and reproductive functions, may influence inflammatory processes. This work examines the impact of OXY on LPS-induced testicular damage, aiming to elucidate its therapeutic potential in addressing inflammatory disorders and broadening the comprehension of its functions beyond conventional neuroendocrine roles.

Background: Limb-salvage surgery for malignant bone tumors can be associated with considerable perioperative blood loss. The aim of this randomized controlled trial was to assess the safety and efficacy of the intraoperative infusion of tranexamic acid (TXA) in children and adolescents undergoing limb-salvage surgery.
Methods: All participants were <18 years of age at the time of surgery and diagnosed with a malignant bone tumor of the femur that was treated with resection and reconstruction with a megaprosthesis.
Do We Need a Fluid Bolus? The Necessary Refinement of Pediatric Propofol Sedation - a Quality Improvement Project.

Sanford Children's Hospital, Sioux Falls, South Dakota.
Background: Propofol is commonly used for pediatric MRIs to minimize patient movement. At our institution, intensivists typically administer a prophylactic 20 ml/kg saline bolus to maintain blood pressure (BP) during propofol sedation. This quality improvement project assessed whether a 10 ml/kg and a completely eliminated saline bolus are as effective as the standard 20 ml/kg bolus in completing pediatric propofol sedation and maintaining Mean Arterial Pressure (MAP).
