Certain aspects of OPSI (Overwhelming Post-Splenectomy Infection) are examined, mainly its considerable gravity, its relatively high incidence, especially in children; its difficult prophylaxis with a report on personal experience of ectopic autotransplant of spleen tissue in two young patients after splenectomy for traumatic rupture. The technique was found to be simple and quickly performed. Scintigraphic follow-up for over 4 years after the operation showed satisfactory growth in the transplanted spleen tissue.

Background: Despite recent advances in immunotherapy, a substantial population of late-stage melanoma patients still fail to achieve sustained clinical benefit. Lack of translational preclinical models continues to be a major challenge in the field of immunotherapy; thus, more optimized translational models could strongly influence clinical trial development. To address this unmet need, we designed a preclinical model reflecting the heterogeneity in melanoma patients' clinical responses that can be used to evaluate novel immunotherapies and synergistic combinatorial treatment strategies.

Introduction: The spleen is a responsible significant part of the immune system; after Splenectomy following trauma, the immune system changes; splenic autotransplantation can preserve the immune system after trauma and Splenectomy.
Background: Patients can be protected from immune dysfunction by autotransplanting splenic tissues after splenectomy following trauma because their immune systems and spleens are changed. Patients can gain their immune function after splenic autotransplantation.

Background: Splenectomy may lead to severe postoperative complications, including sepsis and cancers. A possible solution to this problem is heterotopic autotransplantation of the spleen. Splenic autografts rapidly restore the regular splenic microanatomy in model animals.

Although autografts represent the gold standard for anterior cruciate ligament (ACL) reconstruction, tissue-engineered ACLs provide a prospect to minimize donor site morbidity and limited graft availability. This study characterizes the ligamentogenesis in embroidered poly(L-lactide-co-ε-caprolactone) (P(LA-CL)) / polylactic acid (PLA) constructs using a dynamic nude mice xenograft model. (P(LA-CL))/PLA scaffolds remained either untreated (co) or were functionalized by gas fluorination (F), collagen foam cross-linked with hexamethylene diisocyanate (HMDI) (coll), or F combined with the foam (F + coll).

Introduction: Abdominal splenosis is a rare condition where autotransplanted ectopic spleen tissue is found in the abdominal cavity after spleen injury or splenectomy. While abdominal splenosis is mostly described as asymptomatic, bowel splenosis can present with abdominal pain, obstipation or gastrointestinal (GI) bleeding. Scarce information on bowel splenosis exists and high index of suspicion is needed for diagnosis.
