Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H2 blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement...

Amotosalen and ultraviolet A photochemical-based pathogen reduction using the InterceptTM Blood System is an effective and established technology for platelet and plasma components, which is adopted in more than 40 countries worldwide. Several reports point towards a reduced platelet function after Amotosalen/UVA exposure. The current study was undertaken to identify the mechanisms responsible for the early impairment of platelet function by the InterceptTM Blood System. Twenty-five platelet apheresis units were collected from healthy volunteers following standard procedures and split into 2 components, one untreated and the other treated with Amotosalen/UVA...

Congenital platelet function disorders are often the result of defects in critical signal transduction pathways required for platelet adhesion and clot formation. Mutations affecting RASGRP2, the gene encoding the Rap GTPase activator, CalDAG-GEFI, give rise to a novel, and rare, group of platelet signal transduction abnormalities. We here report platelet function studies for two brothers (P1 and P2) expressing a novel variant of RASGRP2, CalDAG-GEFI(p.Gly305Asp). P1 and P2 have a lifelong history of bleeding with severe epistaxis successfully treated with platelet transfusions or rFVIIa...

The surgical treatment of osteogenesis imperfecta (OI) is negatively influenced by clinical features such as osteoporosis, limb deformities and bone changes caused by bisphosphonate therapy. Blood loss during femoral nailing surgeries in patients with OI is a serious problem. Platelet anomalies have been associated with an elevation of the serum pyrophosphate originating from the platelets during clotting, even if the causality with the platelet dysfunction has not yet been established. To identify predictive risk factors regarding intraoperative bleeding, a retrospective analysis was conducted on 23 patients aged between 6 and 13 years, affected by OI type III, who were treated to correct femoral deformities or to perform an osteosynthesis for femoral shaft fractures, using the Fassier-Duval telescopic nail...

OBJECTIVES: Adipose-derived mesenchymal stem cells (ADMSCs) are a promising strategy for orthopaedic applications, particularly in bone repair. Ex vivo expansion of ADMSCs is required to obtain sufficient cell numbers. Xenogenic supplements should be avoided in order to minimise the risk of infections and immunological reactions. Human platelet lysate and human plasma may be an excellent material source for ADMSC expansion. In the present study, use of blood products after their recommended transfusion date to prepare human platelet lysate (HPL) and human plasma (Hplasma) was evaluated for in vitro culture expansion and osteogenesis of ADMSCs...

The compliant thoracic artificial lung (cTAL) has been studied in acute in vivo and in vitro experiments. The cTAL's long-term function and potential use as a bridge to lung transplantation are assessed presently. The cTAL without anticoagulant coatings was attached to sheep (n = 5) via the pulmonary artery and left atrium for 14 days. Systemic heparin anticoagulation was used. Compliant thoracic artificial lung resistance, cTAL gas exchange, hematologic parameters, and organ function were recorded. Two sheep were euthanized for nondevice-related issues...

BACKGROUND: Acute kidney injury (AKI) can happen due to different factors such as anemia. Packed cell (PC) transfusion is an important cause of AKI occurrence. The aim of the study is to investigate whether appropriate blood component (BC) therapy can reduce blood transfusion and it would result in AKI decreasing. MATERIALS AND METHODS: We conducted a cohort study of 1388 patients who underwent cardiac surgery in one university hospital. A serum creatinine higher than 2 mg/dl, renal disease history, renal replacement therapy (chronic dialysis) were our exclusion criteria...

Therapeutic plasma exchange (TPE) in neonates and small infants is a treatment method at the forefront that may become a potentially life-saving procedure in a wide array of severe conditions. Indications for TPE in the pediatric population have been mainly derived from adult literature, with neonatal hyperbilirubinemia being the most notable exception. The only alternative to TPE in small pediatric patients is manual blood exchange transfusion, which, however, bears an unacceptably high risk of severe complications...

BACKGROUND: Admission hypocalcemia predicts both massive transfusion and mortality in severely injured patients. However, the effect of calcium derangements during resuscitation remains unexplored. We hypothesize that any hypocalcemia or hypercalcemia (either primary or from overcorrection) in the first 24 hours after severe injury is associated with increased mortality. METHODS: All patients at our institution with massive transfusion protocol activation from January 2013 through December 2014 were identified...

BACKGROUND: Bleeding is a leading cause of preventable death following severe injury. Prothrombin complex concentrates (PCC) treat inborn coagulation disorders and reverse oral anticoagulants, but are proposed for use in "factor-based" resuscitation strategies. Few studies exist for this indication in acidosis, or that compare 3-factor (3PCC) versus 4-factor (4PCC) products. We aimed to assess and compare their safety and efficacy in a porcine model of severe hemorrhagic shock and coagulopathy...

INTRODUCTION: The coagulopathy of trauma, illustrated by a short R-time, is common and well understood. The physiology behind this may be early thrombin burst with rapid clot formation. Rapid consumption of fibrinogen, however, may result in weak clot and substrate depletion, resulting in low MA. While these characteristics are interesting, utilizing TEG to identify those at risk for subsequent bleeding diathesis, especially in those who do not demonstrate early signs of physiologic derangement, is challenging...

Nicole P Juffermans, Alexander P Vlaar
After the consensus definition of transfusion-related acute lung injury (TRALI), studies have shown that the incidence of TRALI is high in critically ill and injured patients. When another risk factor for lung injury is present in these patients, the term "possible TRALI" is used. In the past years, both animal and clinical studies have taught us that a predisposing inflammatory risk factor is frequently present in TRALI, if not mandatory. The decline in the incidence of TRALI after implementation of the use of male-only plasma as observed in general hospital patients is also seen in the critically ill and injured, suggesting that antibodies play a role in possible TRALI...

HEV infections are mainly food- and water-borne but transfusion-transmission has occurred in both developing and developed countries. The infection is usually asymptomatic but it can lead to fulminant hepatitis in patients with underlying liver disease and pregnant women living in developing countries. It also causes chronic hepatitis E, with progressive fibrosis and cirrhosis, in approximately 60% of immunocompromised patients infected with HEV genotype 3. The risk of a transfusion-transmitted HEV infection is linked to the frequency of viremia in blood donors, the donor virus load and the volume of plasma in the final transfused blood component...

Ahmed S Said, Allan Doctor
Here we review recent data and the evolving understanding of the role of red blood cell-derived microparticles (RMPs) in normal physiology and in disease progression. Microparticles (MPs) are small membrane vesicles derived from various parent cell types. MPs are produced in response to a variety of stimuli through several cytoskeletal and membrane phospholipid changes. MPs have been investigated as potential biomarkers for multiple disease processes and are thought to have biological effects, most notably in: promotion of coagulation, production and handling of reactive oxygen species, immune modulation, angiogenesis, and in apoptosis...
