RATIONALE: Haemolytic-uremic syndrome is a rare but serious complication of bacterial and viral infections, which is characterized by the triad of: acute renal failure, microangiopathic haemolytic anemia and thrombocytopenia, sometimes severe, requiring peritoneal dialysis. In Europe, hemolytic-uremic syndrome (HUS) in paediatric pathology is primarily caused by Shiga toxin-producing Escherichia coli (STEC) O157, followed by O26. Beside these etiologies, there are other bacterial and viral infections, and also noninfectious ones that have been associated to lead to HUS as well: in the progression of neoplasia, medication-related, post-transplantation, during pregnancy or associated with the antiphospholipid syndrome, systemic lupus erythematosus or family causes with autosomal dominant or recessive inheritance...

A 67-year-old right-handed woman presented with dysarthria, left upper extremity weakness and right-sided neglect of 3 hours duration. Imaging of the brain revealed acute right middle cerebral artery stroke; however, tissue plasminogen activator could not be administered due to severe thrombocytopenia. A peripheral smear revealed schistocytes and the patient was treated empirically for thrombotic thrombocytopenic purpura (TTP) with therapeutic plasma exchange. An extensive workup revealed no embolic source or other cause for stroke, and a diagnosis of large vessel infarct secondary to TTP was made...

BACKGROUND: Dengue is a leading cause of fever and mimics other acute febrile illnesses (AFI). In 2009, the World Health Organization (WHO) revised criteria for clinical diagnosis of dengue. METHODOLOGY/PRINCIPAL FINDINGS: The new WHO 2009 classification of dengue divides suspected cases into three categories: dengue without warning signs, dengue with warning signs and severe dengue. We evaluated the WHO 2009 classification vs physicians' subjective clinical diagnosis (gestalt clinical impression) in a large cohort of patients presenting to a tertiary care center in southern Sri Lanka hospitalized with acute febrile illness...

We report a case of glomerular basement membrane crescentic glomerulonephritis and multicentric Castleman disease-associated interstitial nephritis in a patient with human immunodeficiency virus (HIV) infection. The patient received corticosteroids, cyclophosphamide, and plasmapheresis, and within 3 weeks, there was worsening thrombocytopenia, anemia, and renal function requiring initiation of hemodialysis. He then received 8 weekly doses of rituximab, and there was steady improvement in renal function, such that he stopped dialysis within 6 weeks and has remained in disease remission at 1-year follow-up...

Patients with hematological malignancies often have severe thrombocytopenia, which poses problems when making thrombosis management decisions. A retrospective study was conducted to analyze the clinical outcomes associated with different management options in acute leukemic patients with thrombocytopenia (≤ 50 × 109/L) following an acute venous thromboembolic event. A total of 74 patients were divided into three treatment groups: observation only (n = 30); anticoagulation (n = 23); or inferior vena cava placement (n = 21)...

Escherichia coli is a bacterium that is an important part of the intestinal tract; however, it has the potential to become pathogenic. Shiga toxin-producing E coli (STEC) is a leading cause of E coli infections and has led to outbreaks in North America. Transmission is through ingestion of contaminated food sources, and via infected humans and animals. Young children infected with STEC are at high risk for developing hemolytic uremic syndrome (HUS). HUS is a clinical syndrome characterized by macroangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure...

Heparin-induced thrombocytopenia is a well-known, life-threatening complication that occurs in 5% of patients exposed to heparin. It causes thrombocytopenia in roughly 85% to 90% of affected individuals, with expected recovery in approximately 4 to 10 days following heparin withdrawal. However, there is an entity known as refractory heparin-induced thrombocytopenia with thrombosis in which patients have prolonged thrombocytopenia, refractory to the current standard of care. We present one such case of a 48-year-old male with R-ISS (Revised International Staging System) stage II kappa light chain multiple myeloma in stringent complete response status postinduction therapy...

BACKGROUND: Despite an abundance of therapeutic options, advanced-stage follicular lymphoma remains incurable. Furthermore, the ideal sequence and absolute benefit of post-induction therapy is unclear. We designed SWOG S0801 to assess the efficacy and safety of consolidative radioimmunotherapy and sequential maintenance rituximab following chemoimmunotherapy. METHODS: For this single-arm, phase 2, multicentre study, we enrolled patients aged 18 years and older with a diagnosis of stage III, IV, or bulky stage II follicular lymphoma, grades 1, 2, or 3a, who had not received previous therapy, from from 20 institutions within the United States National Cancer Institute Clinical Trials Network...

Oncogene amplification is uncommon in acute myeloid leukemia (AML). Cytogenetically, it is primarily found as double minute chromosomes (dmin) or homogeneously staining regions (hsr). A 62-year-old woman was admitted to our hospital because of anemia and thrombocytopenia. Her bone marrow was hypercellular with 78.6% myeloperoxidase- positive blasts. Some had micronuclei. The patient was diagnosed with AML M2 and remains in complete remission (CR) after induction therapy. G-banding at diagnosis showed 51,XX,t(11;16)(q13;p11...
