BACKGROUND: Splenic injury frequently occurs after blunt abdominal trauma; however, limited epidemiological data regarding mortality are available. We aimed to investigate mortality rate trends after blunt splenic injury in Japan. METHODS: We retrospectively identified 1,721 adults with blunt splenic injury (American Association for the Surgery of Trauma splenic injury scale grades III-V) from the 2004-2014 Japan Trauma Data Bank. We grouped the records of these patients into 3 time phases: phase I (2004-2008), phase II (2009-2012), and phase III (2013-2014)...

A hallmark of acute hepatic injury is the recruitment of neutrophils, monocytes and lymphocytes, including natural killer (NK) or T cells, towards areas of inflammation. The recruitment of leukocytes from their reservoirs bone marrow or spleen into the liver is directed by chemokines such as CCL2 (for monocytes) and CCL5 (for lymphocytes). We herein elucidated the impact of chemokine receptor inhibition by the dual CCR2 and CCR5 inhibitor cenicriviroc (CVC) on the composition of myeloid and lymphoid immune cell populations in acute liver injury...

INTRODUCTION: The non operative management (NOM) is the standard management of splenic and liver blunt trauma in pediatric patients.Hemodynamic instability and massive transfusions have been identified as management failures. Few studies evaluate whether there exist factors allowing anticipation of these events. The objective was to identify factors associated with the failure of NOM in splenic and liver injuries for blunt abdominal trauma. PATIENTS AND METHOD: Retrospective analysis between 2007-2015 of patients admitted to the pediatric surgery at University Hospital Saint Vincent Foundation with liver trauma and/or closed Spleen...

BACKGROUND: There is a paucity of data on the impact of splenectomy on peri-operative outcomes after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). We report the largest series to date which addresses this topic. METHODS: Nine hundred and thirty six consecutive patients underwent CRS/HIPEC from 1996 to 2016 at a high-volume institution in Sydney, Australia. Of these, 418 (45%) underwent splenectomy. Peri-operative complications were graded according to the Clavien-Dindo Classification...

BACKGROUND: Trauma is the main cause of morbidity and mortality in the pediatric population. Blunt trauma to the abdomen accounts for the majority of abdominal injuries in children. Pancreatic injury, although uncommon (2 to 9%), is the fourth most common solid organ injury. Unlike other solid organ injuries, pancreatic trauma may be subtle and difficult to diagnose. Computed tomography currently is the imaging modality of choice. As the incidence of pancreatic injury in children sustaining blunt abdominal trauma is low, management remains a challenge...

Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood...

Natural IgM anti-leukocyte autoantibodies (IgM-ALAs) inhibit inflammation by several mechanisms. Here, we show that pan-B cells and bone marrow-derived dendritic cells (BMDCs) are switched to regulatory cells when pretreated ex vivo with IgM. B cells are also switched to regulatory cells when pretreated ex vivo with CpG but not with LPS. Pre-emptive infusion of such ex vivo induced regulatory cells protects C57BL/6 mice from ischemia-induced acute kidney injury (AKI) via regulation of in vivo NKT-1 cells, which normally amplify the innate inflammatory response to DAMPS released after reperfusion of the ischemic kidney...

Transcriptionally activated monocytes are recruited to the heart after acute myocardial infarction (AMI). After AMI in mice and humans, the number of extracellular vesicles (EVs) increased acutely. In humans, EV number correlated closely with the extent of myocardial injury. We hypothesized that EVs mediate splenic monocyte mobilization and program transcription following AMI. Some plasma EVs bear endothelial cell (EC) integrins, and both proinflammatory stimulation of ECs and AMI significantly increased VCAM-1-positive EV release...

The importance and safety of non-operative management (NOM) of Blunt Splenic Injury (BSI) has been established in children and adults over recent decades. However, studies have shown higher operation rates in adults. There is international evidence that when children are managed in adult centres, operation rates are higher while adolescents in paediatric centres, are operated on in line with paediatric guidelines. This difference between children and young adults, and the factors responsible, have not been examined in New South Wales (NSW)...

BACKGROUND & AIMS: The increase in use of anesthesia assistance (AA) to achieve deep sedation with propofol during colonoscopy has significantly increased colonoscopy costs without evidence for increased quality and with possible harm. We investigated the effects of AA on colonoscopy complications, specifically bowel perforation, aspiration pneumonia, and splenic injury. METHODS: In a population-based cohort study using administrative databases, we studied adults in Ontario, Canada undergoing outpatient colonoscopy from 2005 through 2012...

Sepsis is characterized by an innate immune response and the following immune dysfunction which can increase the emergence of secondary infections. Ethyl pyruvate (EP) has multiple immunoregulation functions in several serious illnesses, such as burn injury, severe sepsis and acute respiratory syndrome. However, little data was shown the effect of EP administration on immunosuppression post-CLP and the following secondary infection. The cecal ligation and puncture (CLP) followed by the induction of Pseudomonas aeruginosa (PA) was used as a clinically relevant two-hit model of sepsis...

Spleen injuries are among the most frequent trauma-related injuries. At present, they are classified according to the anatomy of the injury. The optimal treatment strategy, however, should keep into consideration the hemodynamic status, the anatomic derangement, and the associated injuries. The management of splenic trauma patients aims to restore the homeostasis and the normal physiopathology especially considering the modern tools for bleeding management. Thus, the management of splenic trauma should be ultimately multidisciplinary and based on the physiology of the patient, the anatomy of the injury, and the associated lesions...

Renal Artery Stenosis (RAS) is an important cause of treatment-resistant hypertension. Uncontrolled hypertension with RAS can cause progressive chronic kidney disease (CKD) leading to end-stage kidney disease. Therapeutic revascularisation can be helpful in appropriate circumstances where pharmaceutical intervention has failed and significant renovascular disease contributes to resistant hypertension. We present an interesting case of a Caucasian male with peripheral vasculopathy, abdominal aortic aneurysm (AAA), single functioning kidney and ostial RAS caused by stent struts from an endovascular AAA stent graft...

OBJECTIVE: To investigate effect of oxidized low-density lipoprotein (ox-LDL) on memory CD8(+) T cell subpopulation differentiation in mice with autoimmune diabetes. METHODS: Cultured splenic CD8(+) T cells from pre-diabetic NOD mice isolated with magnetic beads were treated with 30 µg/mL ox-LDL and 10 U/mL interleukin-2 (IL-2) for 24 h and the control cells were treated with IL-2 only. Flow cytometry was used to determine the percentage of splenic CD8(+)IFN-γ(+) T cells, expressions of CD8, CD44 and CD62L on the T cells, and the activation of T cell factor-1 (TCF-1) and STAT-3...

The spleen is one of the most frequently injured organs in blunt abdominal trauma. In the past decades, the treatment of patients with blunt splenic injury has shifted from operative to non-operative management. The knowledge of physiology and immunology of the spleen have been the main reasons to develop techniques for splenic salvage. The advances in high-resolution imaging techniques, as well as less invasive procedures, including angiography and angioembolization, have allowed a higher rate of success in the non-operative management...

Spleen rupture in an extremely premature newborn is very rare event. High index of suspicion is required to make timely diagnosis and thereafter appropriate management. We present a rare case of an extremely premature, extremely low birthweight newborn who presented with severe anemia secondary to splenic rupture. It was managed conservatively without splenectomy resulting in complete resolution of symptoms. Although non-operative management of pediatric splenic injuries is now recognized as the treatment of choice, there is very little experience in premature newborns...
