Haemotoxicity of snakes: a review of pathogenesis, clinical manifestations, novel diagnostics and challenges in management.

Haemotoxicity is the most common complication of systemic envenoming following snakebite, leading to diverse clinical syndromes ranging from haemorrhagic to prothrombotic manifestations. Key haematological abnormalities include platelet dysfunction, venom-induced consumption coagulopathy, anticoagulant coagulopathy and organ-threatening thrombotic microangiopathy. Diagnostic methods include the bedside whole blood clotting test, laboratory coagulation screening and other advanced methods such as thromboelastogram and clot strength analysis.

Snakebite-associated acute kidney injury in South Asia: narrative review on epidemiology, pathogenesis and management.

Snakebite-associated acute kidney injury (AKI) poses a significant health burden in the South Asia region, resulting in considerable morbidity and mortality. Multiple factors contribute to the pathogenesis of AKI following snakebites, including hypotension, intravascular haemolysis, disseminated intravascular coagulation, rhabdomyolysis, thrombotic microangiopathy (TMA) and direct nephrotoxicity. Clinical features manifest as anuria, oliguria, haematuria, abdominal pain and hypertension.

"Bone marrow-liver-spleen-type diffuse large B-cell lymphoma" presenting with cold autoimmune hemolytic anemia: a case report.

Introduction: Primary bone marrow diffuse large B-cell lymphoma is a rare clinical entity, and the "bone marrow-liver-spleen" type of diffuse large B-cell lymphoma is rarer, with only a few published cases in literature. Though bone marrow-liver-spleen-type diffuse large B-cell lymphoma has unique presentations such as fever, cytopenias, and hemophagocytic lymphohistiocytosis, no cases with cold autoimmune hemolytic anemia have been reported.

Case Presentation: A 39-year-old Sri Lankan woman, previously healthy, presented with shortness of breath, productive cough, and fever for 4 days.

Donor-type bone marrow aplasia following hematopoietic stem cell transplantation in a child with a novel variant.

Pathogenic variants in the genes ( and cause bone marrow failure with characteristic syndromic features. We report a case of a previously healthy, 3-year-old boy with no dysmorphology, who presented with severe aplastic anemia and a novel variant in the gene. His father, elder brother and sister who harbored the same variant were completely healthy.

Hirudin versus citrate as an anticoagulant for ROTEM whole blood impedance aggregometry in thrombocytopenic patients.

Citrate is widely used as an anticoagulant for platelet function tests (PFTs). Due to an intrinsic inhibitory effect of citrate on platelet function, hirudin is used as an alternative. However, studies comparing the effect of these anticoagulants on rotational thromboelastometry (ROTEM) platelet whole blood impedance aggregometry in thrombocytopenic patients are scant.
