BACKGROUND: This study was designed to determine the clinical significance of preoperative thrombocytosis in patients with malignant peritoneal mesothelioma (MPM) undergoing operative cytoreduction (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). CRS and HIPEC have been associated with prolonged survival in patients with MPM and is the preferred treatment in select patients. However, patient selection criteria remain ill-defined for this operation that is also associated with significant morbidity and mortality...

POEMS syndrome is a paraneoplastic disorder secondary to an underlying plasma cell dyscrasia. By definition, all patients with POEMS syndrome must display polyneuropathy and monoclonal plasma cell disorder. In addition, at least one major criterion (Castleman's disease, sclerotic bone lesions, or vascular endothelial growth factor elevation) and one minor criterion (organomegaly, extravascular volume overload, endocrinopathy, skin changes, papilledema, thrombocytosis, or polycythemia) are required for diagnosis...

BACKGROUND: Unrecognized pseudohyperkalemia (PHK), defined as an artificial increase in measured potassium concentration, due to thrombocytosis and leukocytosis can lead to inappropriate patient treatment. Understanding the laboratory and patient characteristics that increase risk of PHK is key to preventing diagnostic errors. METHODS: Serum/plasma potassium results collected at 2 laboratories over 4years were selected based on blood cell counts collected within 24h and whole blood potassium concentrations determined within 2h of the serum/plasma sample...

For the patients with essential thrombocythemia (ET), systemic thrombosis presents as one of the most dangerous complications. It's been widely accepted that acute coronary syndrome (ACS) is a kind of thrombotic diseases. However, there are very few case reports about ET first presenting as ACS. For some patients diagnosed as ACS, but without markedly elevated platelet, underlying ET was missed. And there are some controversies in the principles and target of treatment in those patients. We reported three cases of ACS, in which the patients who did not have common risk factors for coronary artery diseases and presented only mild atherosclerotic stenosis during coronary angiography, one of which had recurrent coronary artery thrombosis...

Chronic myeloproliferative disorders (CMPD) share a stem cell-derived clonal myeloproliferation. This group of disorders includes essential thrombocythemia (ET), polycythemia vera (PV), chronic myeloid leukemia (CML), and primary myelofibrosis (PMF), with the respective features of thrombocytosis, erythrocytosis, and bone marrow fibrosis(1). These disorders can be associated with genetic mutations affecting protein tyrosine kinases, resulting in different configurations of abnormal signal transduction. The Janus tyrosine kinase 2 (JAK2) mutation can be used as a key diagnostic tool for diagnosing MPDs, specifically, ET, PV, and PMF(2)...

BACKGROUND Hypercalcemia associated with chronic myeloid leukemia (CML) is an ominous sign. Although rare, several cases have been reported and multiple pathophysiologic mechanisms have been independently proposed. We present a patient case and a literature review of the clinical presentation and mechanisms of CML-associated hypercalcemia. CASE REPORT A 58-year-old male with a past medical history of CML diagnosed six years earlier, presented to the emergency department with one week of acute confusion, disorientation, polyuria, and polydipsia...

BACKGROUND: Anastomotic leak is a major source of morbidity in colorectal operations and has become an area of interest in performance metrics. It is unclear whether anastomotic leak is associated primarily with surgeons' technical performance or explained better by patient characteristics and institutional factors. We sought to establish if anastomotic leak could serve as a valid quality metric in colorectal operations by evaluating provider variation after adjusting for patient factors...

Essential thrombocythemia (ET) is a myeloproliferative disorder characterized by persistent thrombocytosis (>450 × 10(9)/L). Patients with ET are at risk for thrombotic or hemorrhagic complications especially during cardiovascular operations. We discuss a patient with ET requiring coronary artery bypass grafting with a presenting platelet count of 1631 × 10(9)/L. Platelet reduction with an intraoperative autologous transfusion technique decreased the platelet count to 758 × 10(9)/L before initiation of cardiopulmonary bypass...

Previous studies reported inconsistent findings about the relationship between pretreatment thrombocytosis and survival in patients with cervical cancer. This study aimed to evaluate the prognostic significance of thrombocytosis in cervical cancer. We searched databases to identify relevant articles. Pooled hazard ratios (HRs), odds ratios (ORs), and 95% confidence intervals (CIs) were calculated. Fourteen studies including 3,394 patients were eligible for the meta-analysis. Overall, an elevated platelet count was significantly associated with inferior overall survival (OS, hazard ratio [HR]: 1...

The 2016 World Health Organization (WHO) diagnostic criteria for myeloproliferative neoplasms (MPN) underscore the prognostically-relevant distinction between essential thrombocythemia (ET) and prefibrotic primary myelofibrosis (pre-PMF). In addition, leukocytosis has been identified as an important prognostic marker in otherwise WHO-defined ET. However, controversy remains regarding the objectivity of morphologic criteria in distinguishing ET from pre-PMF and the precise prognostic cutoff values for leukocytosis...

DISEASE OVERVIEW: Ring sideroblasts (RS) are erythroid precursors with abnormal perinuclear mitochondrial iron accumulation. Two myeloid neoplasms defined by the presence of RS, include refractory anemia with ring sideroblasts (RARS), now classified under myelodysplastic syndromes with RS (MDS-RS) and RARS with thrombocytosis (RARS-T); now called myelodysplastic/myeloproliferative neoplasm with RS and thrombocytosis (MDS/MPN-RS-T). DIAGNOSIS: MDS-RS is a lower risk MDS, with single or multilineage dysplasia (SLD/MLD), <5% bone marrow (BM) blasts and ≥15% BM RS (≥5% in the presence of SF3B1 mutations)...

BACKGROUND: Tumor lysis syndrome can occur after treatment of fast-growing cancers. Early detection of tumor lysis is crucial to minimize the toxic effects on organs and potentially life-threatening complications. METHODS: A patient with acute monocytic leukemia presented with spurious thrombocytosis. A peripheral blood smear was stained with alpha-naphthyl butyrate esterase to discriminate tumor cell fragments from platelets. RESULTS: Peripheral blood smears showed widespread leukemic cell fragmentation...

Normal iron levels are required to prevent thrombocytosis by inhibiting thrombopoiesis. Thrombocytosis is usually associated with a mild iron deficiency and is the result of a lack of inhibition of thrombopoiesis. Study participants were 430 iron deficiency anemia (IDA) patients. Ten (10) mL of venous blood were collected for the subjects. Ferritin analysis was done by ELISA method while Hemogram analysis was done by auto-analyzer. Factor V Leiden, PRTG20210A, and MTHFR C677T genotype analysis was performed by PCR-RFLP method...

The diagnosis of essential thrombocythemia and polycythemia vera is often made during a thrombotic event which can be serious. Philadelphia-negative chronic myeloproliferative neoplasia patients have an increased thrombotic risk. This is assessed using various scoring systems but these are far from ideal and individual risk. The currend trend to personalised medicine requires finding the most useful thrombotic risk biomarker in these patients. Routine tests for coagulation do not take account of both pro- and anti-coagulant factors which is why these tests are not useful in patients with Philadelphia-negative myeloproliferative neoplasms...

Hexahydro-1-nitroso-3,5-dinitro-1,3,5-triazine (MNX), environmental degradation product of munitions hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), causes seizures in rats with acute oral exposure like parent RDX. Our previous studies have additionally reported hematotoxicity with acute MNX exposure manifested as myelosuppression, anemia and splenic hemosiderosis. This study explored whether MNX administered subchronically continued to target bone marrow to elicit peripheral blood cytopenia. Female Sprague-Dawley rats were gavaged daily for 4 or 6 weeks with 47 mg kg(-1)  day(-1) MNX (¼ LD50 ) or vehicle (5% dimethyl sulfoxide in corn oil) and hematological and clinical chemistry parameters, spleen weights, spleen and bone marrow histopathology and immunohistochemistry with ED1 anti-CD68 macrophage marker were evaluated 24 h after the last dose...

Castleman disease (CD) describes a group of three rare and poorly understood lymphoproliferative disorders that have heterogeneous clinical symptoms and common lymph node histopathological features. Unicentric CD (UCD) involves a single region of enlarged nodes. Multicentric CD (MCD) involves multiple regions of enlarged lymph nodes, constitutional symptoms, and organ dysfunction due to a cytokine storm often including interleukin 6. MCD is further divided into Human Herpes Virus-8 (HHV-8)-associated MCD, which occurs in immunocompromised individuals, and HHV-8-negative/idiopathic MCD (iMCD)...
