Melioidosis well known as a 'great mimicker' is caused by Burkholderia pseudomallei. Even though majority of the patients present with acute infection, around 18 % can present as chronic infection. These latent foci of infection may reactivate to cause fulminant infection at a later date. Due to lack of clinical suspicion and good laboratory facility latent infections are often misdiagnosed and treated as tuberculosis. Chronic splenic granuloma is a rare manifestation of Melioidosis . Deep seated abscess requires atleast 4 weeks of intensive treatment with intravenous antibiotics...

Thrombocytopenia is a well-known manifestation of acute tropical infectious diseases. The role of platelets in infections has received much attention recently because of their emerging activities in modulation of inflammatory responses, host defense, and vascular integrity. However, while many studies have addressed thrombocytopenia in tropical infections, abnormalities in platelet function have been largely overlooked. This is an important research gap, as platelet dysfunction may contribute to the bleeding tendency that characterizes some tropical infections...

Evans syndrome is an uncommon disease characterized by a combination of autoimmune hemolytic anemia and autoimmune thrombocytopenia concomitantly or sequentially with a positive direct Coombs test in the absence of any underlying known cause. Here, we present a case of an adult patient who underwent living-donor liver transplant that was preceded by bone marrow transplant 20 years earlier from the same HLA identical donor and who received a single-agent immunosuppressive therapy for only 2 months as prophylaxis against graft-versus-host disease...

On June 26, 2017, a hospital in southern Utah notified the Utah Department of Health of Shiga toxin-producing Escherichia coli (STEC) O157:H7 infections in two children from a small community on the Arizona-Utah border. Both children developed hemolytic uremic syndrome, characterized by hemolytic anemia, acute kidney failure, and thrombocytopenia and died within a few days of illness onset. Over the next few days, several more STEC-associated illnesses were reported in residents of the community. A joint investigation by local and state health agencies from Arizona and Utah and CDC was initiated to identify the outbreak source and prevent additional cases; a total of 12 cases were identified, including the two children who died...

Background: Snake bites are a neglected public health problem in all tropical countries, and particularly in Malabar region of Kerala, India. Demographic characteristics and clinical parameters vary in this part of the world, and studies based on them are scarce. Increased incidence of capillary leak syndrome (CLS) in hemotoxic snake bites and emergence of cases of hump-nosed pit viper (HNPV, Hypnale hypnale ) envenomation are some notable features seen here. Objectives: The study was conducted to assess the epidemiological profile and clinical features to identify factors contributing to outcome in patients with venomous snakebites...

Bérangère S Joly, Paul Coppo, Agnès Veyradier
Child-onset thrombotic thrombocytopenic purpura (TTP) is a rare entity of thrombotic microangiopathy (TMA). The pathophysiology of the disease is based on a severe functional deficiency of ADAMTS13 (activity <10%), the specific von Willebrand factor (VWF)-cleavage protease. This deficiency may be either acquired (associated anti-ADAMTS13 autoantibodies) or congenital (resulting from biallelic mutations of ADAMTS13 gene). ADAMTS13 deficiency is responsible for the accumulation of high molecular weight multimers of VWF and the formation of platelet thrombi in the microcirculation...

BACKGROUND: Intravenous arsenic trioxide plus all-trans retinoic acid (ATRA) without chemotherapy is the standard of care for non-high-risk acute promyelocytic leukaemia (white blood cell count ≤10 × 109 per L), resulting in cure in more than 95% of cases. However, a pilot study of treatment with oral arsenic realgar-Indigo naturalis formula (RIF) plus ATRA without chemotherapy, which has a more convenient route of administration than the standard intravenous regimen, showed high efficacy...

Severe thrombocytopenia (≤50x109 platelets/L) due to hematological malignancy and intensive chemotherapy is associated with an increased risk of clinically significant bleeding. Since the bleeding risk is not linked to the platelet count only, other hemostatic factors must be involved. In 77 patients with acute leukemia, multiple myeloma or malignant lymphoma, who experienced chemotherapy-induced thrombocytopenia, we studied platelet function. Platelets from all patients - independent of disease or treatment type - were to a variable extent compromised in Ca2+ flux, integrin αIIbβ3 activation and P-selectin expression, when stimulated with a panel of agonists...

BACKGROUND: Adverse drug reactions (ADRs), also called as drug adverse events (AEs), are reported in the FDA drug labels; however, it is a big challenge to properly retrieve and analyze the ADRs and their potential relationships from textual data. Previously, we identified and ontologically modeled over 240 drugs that can induce peripheral neuropathy through mining public drug-related databases and drug labels. However, the ADR mechanisms of these drugs are still unclear. In this study, we aimed to develop an ontology-based literature mining system to identify ADRs from drug labels and to elucidate potential mechanisms of the neuropathy-inducing drugs (NIDs)...

A 76-year-old woman suddenly developed anasarca and a fever, and an examination revealed thrombocytopenia, reticulin fibrosis, and acute kidney injury, yielding the diagnosis of TAFRO syndrome. Renal replacement therapy and steroid treatment were soon started. Her proteinuria was minor at first; however, once the kidney function improved, nephrotic syndrome occurred. A kidney biopsy showed membranoproliferative glomerulonephritis-like glomerulopathy with massive macrophage infiltration. Although kidney dysfunction is often observed in TAFRO syndrome patients, its detailed mechanism is unclear...

BACKGROUND: Thrombotic thrombocytopenic purpura and peripartum cardiomyopathy are potentially lethal complications of pregnancy. We describe a case in which both of these developed in the same patient. The etiologies of both conditions remain uncertain, but they share immune hyperreactivity as a possible cause. CASE PRESENTATION: A 33-year-old Lankan primigravida gave birth at 38 weeks of gestation by cesarean section when she presented with right-sided abdominal pain and a provisional diagnosis of appendicitis...

Anticoagulation for cardiopulmonary bypass (CPB) is required to prevent acute disseminated intravascular coagulation and clot formation within the bypass circuit. Unfractionated heparin is the standard anticoagulant for CPB due to its many advantages and long history of successful use. However, heparin has the unique drawback of triggering Heparin-PF4 (PF4) antibodies potentially leading to heparin-induced thrombocytopenia (HIT). We have limited data regarding reformation of antibodies if a patient has had a prior (remote) antibody production or full HIT...

BACKGROUND: Acute kidney injury complicating high-dose methotrexate therapy increases the risk for severe mucositis, myelosuppression, and death. It is unclear whether high-dose leucovorin and supportive therapy without the use of glucarpidase can reduce toxicity from high-dose methotrexate. STUDY DESIGN: The charts of all patients at Memorial Sloan Kettering Cancer Center whose methotrexate drug levels at 48 or 72 hours after administration were ≥10 times the toxic level were reviewed between January 2000 and December 2011...

Collapsing glomerulopathy (CG) is a distinct histopathologic pattern of glomerular injury characterized by global/segmental wrinkling of the glomerular basement membrane with podocyte hyperplasia and hypertrophy along with tubulointerstitial changes. There is no specific treatment for CG due to etiological heterogeneity, and newer insights into the pathogenesis may lead to the development of targeted therapy. The most common form of CG is the primary or idiopathic followed by secondary (due to viral infections, autoimmune disease, drugs, etc...

A 46-year-old male presented with left flank pain and was found to have left nephromegaly with renal vein and inferior vena cava (IVC) thrombus. On hematological evaluation, he had leukocytosis and thrombocytopenia. Further evaluation revealed acute myeloid leukemia (AML). Following initial cytoreductive therapy and supportive care for hyperleukocytosis, he underwent left simple nephrectomy with IVC thrombectomy. Postoperatively, he developed massive thrombosis of infrahepatic IVC with renal failure. Renal venous thrombosis as a rare presentation of AML in adults with leukemic hyperleukocytosis has not been reported...
