Optimized flow cytometric detection of transient receptor potential vanilloid-1 (TRPV1) in human hematological malignancies.

The ectopic overexpression of transient receptor potential vanilloid-1 (TRPV1) has been detected in numerous solid cancers, including breast, prostate, pancreatic, and tongue epithelium cancer. However, the expression of TRPV1 in hematological malignancies remains unknown. Here we show through in silico analysis that elevated TRPV1 mRNA expression occurs in a range of hematological malignancies and presents an optimized flow cytometry method to rapidly assess TRPV1 protein expression for both cell lines and primary patient samples.

Real-World Data on Characteristics and Management of Community Patients Receiving Anticoagulation Therapy Who Presented with Acute Bleeding to the Emergency Department at a Regional Australian Hospital: A Prospective Observational Study.

Objective: To study patients receiving anticoagulants with or without antiplatelet therapy presenting at a regional Australian hospital with bleeding. The main aims are to explore: (1) patients' characteristics and management provided; (2) association between the type of anticoagulant and antiplatelet agent used and the requirement of reversal; (3) and the length of hospital stay (LoS) in conjunction with bleeding episode and management.

Methods: A prospective cross-sectional review of medical records of all patients who presented at a tertiary referral centre with bleeding while receiving anticoagulation therapy between January 2016 and June 2018.

Assessment of von Willebrand disease and pregnancy outcomes at regional Australian hospitals.

Background: von Willebrand disease (vWD) is a heterogeneous hereditary bleeding disorder and is associated with risk of primary postpartum haemorrhage (PPH).

Design And Methods: An observational study at a tertiary referral centre in Australia of 16 women with 23 deliveries with a median age of 27.5 years (range, 21-39; IQR = 9).

Concurrent Hairy Cell Leukemia and Metastatic Merkel Cell Carcinoma.

Hairy cell leukemia (HCL) and Merkel cell carcinoma (MCC) are two rare malignancies with distinct cells of origin. HCL is a lymphoid malignancy of mature B cells, and MCC derives from neuroendocrine cell origin. HCL has a favorable prognosis with most patients achieving long-term remission and potential cure.

A Prospective Randomised Controlled Trial of a Single Intravenous Infusion of Ferric Carboxymaltose vs Single Intravenous Iron Polymaltose or Daily Oral Ferrous Sulphate in the Treatment of Iron Deficiency Anaemia in Pregnancy.

Iron deficiency anaemia (IDA) is the most common nutritional deficiency affecting pregnant women worldwide. This study aims to compare the efficacy and safety of a newly available intravenous (IV) iron preparation, ferric carboxymaltose (FCM), against IV iron polymaltose (IPM), and standard oral iron (ferrous sulphate) for the treatment of IDA in pregnancy. This is an open-labelled prospective randomised controlled trial (RCT) with intention-to-treat analysis conducted at a primary health care facility with a single tertiary referral centre in Launceston.

Fostamatinib for the treatment of adult persistent and chronic immune thrombocytopenia: Results of two phase 3, randomized, placebo-controlled trials.

Spleen tyrosine kinase (Syk) signaling is central to phagocytosis-based, antibody-mediated platelet destruction in adults with immune thrombocytopenia (ITP). Fostamatinib, an oral Syk inhibitor, produced sustained on-treatment responses in a phase 2 ITP study. In two parallel, phase 3, multicenter, randomized, double-blind, placebo-controlled trials (FIT1 and FIT2), patients with persistent/chronic ITP were randomized 2:1 to fostamatinib (n = 101) or placebo (n = 49) at 100 mg BID for 24 weeks with a dose increase in nonresponders to 150 mg BID after 4 weeks.

Successful treatment of concomitant metastatic prostate cancer and B-cell non-Hodgkin's lymphoma with R-EPOCH chemotherapy regimen and antiandrogen therapy.

A 70-year-old man presented with left loin pain without urinary symptoms. Initial investigations with CT showed enlarged para-aortic, mediastinal lymph nodes, right-side renal mass and enlarged prostate. A prostatic-specific antigen (PSA) was alarmingly high at 4750 μg/L (normal <4.

Inherited haemochromatosis with C282Y mutation in a patient with alpha-thalassaemia: a treatment dilemma.

A Caucasian 24-year-old female patient suffers from two hereditary disorders: alpha-thalassaemia, which is prevalent in Asia and rare in Europe, and haemochromatosis, which is prevalent among northern Europe and rare in Asia. The clinical presentation and management of one of these diseases is controversial for the other. She presented 5 years ago with a clinical picture of refractory iron-deficiency anaemia secondary to menorrhagia.

Changes to fibrinolysis in patients with systemic lupus erythematosus are associated with endothelial cell damage and inflammation, but not antiphospholipid antibodies.

We investigated whether changes to fibrinolysis were associated with other manifestations of systemic lupus erythematosus (SLE), including antiphospholipid (APL) antibody status, endothelial damage, and inflammation. Ninety-four patients (36 SLE patients, 58 healthy controls) were recruited from Tasmania, Australia. Circulating levels of plasminogen, α2-antiplasmin, tissue-type plasminogen activator, plasminogen activator inhibitor-1, and thrombin-activatable fibrinolysis inhibitor (TAFI) were measured, as well as APL antibodies (including lupus anticoagulant, anticardiolipin, and antibeta-2 glycoprotein-1 antibodies), soluble E-selectin, and interleukin-6.

Intravenous ferric carboxymaltose versus standard care in the management of postoperative anaemia: a prospective, open-label, randomised controlled trial.

Background: Despite increasing efforts in perioperative management, postoperative iron deficiency anaemia persists, and few data are available about the management of this condition. In this study, we aimed to determine whether giving postoperative intravenous iron (in the form of ferric carboxymaltose) improved iron stores, haemoglobin concentrations, and outcomes following surgery.

Methods: We did a prospective, open-label, randomised, controlled study of patients at two centres (a general hospital and a private health-care centre) in Tasmania, Australia, undergoing elective surgery with functional iron deficiency anaemia (haemoglobin 70-120 g/L and ferritin ≤100 μg/L or iron saturation ≤20%), measured at day 1 postoperatively.

Venous thromboembolism in medical patients during hospitalisation and 3 months after hospitalisation: a prospective observational study.

Objectives: This study was conducted to assess the incidence and risk factors for venous thromboembolism (VTE) in a cohort of medical patients both during the period of hospitalisation and following discharge.

Design: This was a prospective observational study to document the risk profile and incidence of VTE posthospitalisation among all medical patients admitted to our institution during the trial period.

Settings: Primary healthcare.

Review of Management and Outcomes in Women with Thrombophilia Risk during Pregnancy at a Single Institution.

Pregnancy is a hypercoagulable state associated with an increased risk of venous thromboembolic disease (VTE). We retrospectively studied 38 Caucasian pregnant women with thrombophilia risk and compared their obstetric outcomes with a matched cohort without known thrombophilia risk during the period between January 2007 and December 2010. There were (2) cases with factor V Leiden, (6) prothrombin gene mutation, (1) antithrombin III deficiency, (2) protein C deficiency, (3) protein S deficiency, (10) MTHFR mutation, (7) anti-cardiolipin antibodies, and (1) lupus anticoagulant.

Hypereosinophilic syndrome associated with ulcerative colitis presenting with recurrent Loeffler's endocarditis and left ventricular thrombus treated successfully with immune suppressive therapy and anticoagulation.

We reported a case of a 28-year-old Caucasian woman with hypereosinophilic syndrome (HES) associated with ulcerative colitis who presented on separate occasions with Loeffler's endocarditis. She was admitted in 2008 with fever, headache, confusion and visual loss. Diagnostic workup uncovered an eosinophilia of 3.

Ophthalmic manifestations of herpes zoster virus in patients with multiple myeloma following bone marrow transplantation.

We report three patients with ophthalmic herpes zoster (HZ) manifestations on the background diagnosis of multiple myeloma (MM). It seems that immunocompromised status has caused reactivation of the varicella zoster virus (VZV) producing a well-characterised neurological syndrome and subsequent postherpetic neuralgia in two patients. One patient experienced lymphocytic leptomeningitis resulting in unilateral optic neuritis.

Early Application of High Cut-Off Haemodialysis for de-Novo Myeloma Nephropathy is Associated with Long-Term Dialysis-Independency and Renal Recovery.

Background: Multiple myeloma (MM) is a haematological malignancy associated with kidney injury resulting from cast nephropathy, which can be caused by monoclonal free light chains (FLC). It has been demonstrated that early reduction of FLC can lead to a higher proportion of patients recovering renal function with a better outcome, especially if high cut-off haemodialysis (HCO-HD) combined with chemotherapy is used.

Patients And Methods: In this study, four cases with MM nephropathy were treated with HCO-HD and chemotherapy at a single institution during the period from August 2009 to August 2011.

Assessment of whole body MRI and sestamibi technetium-99m bone marrow scan in prediction of multiple myeloma disease progression and outcome: a prospective comparative study.

Objectives: This study aims primarily to determine whether whole body MRI (WB-MRI) and Sestamibi Technetium-99m-bone marrow (MIBI) scans in the same patients produce the same estimate of disease load and location, and secondly, to study possible association between the bone disease detected by these scans and the effect on disease outcome and survival. Bone disease occurs in about 90% of multiple myeloma (MM) patients. There are no data comparing the new diagnostic modalities with WB-MRI and MIBI in MM.

Extensive venous thrombosis in a healthy young man with a short inferior vena cava syndrome treated successfully with rivaroxaban.

We report a case of an incidental finding of congenital absence of the intrahepatic segment of the inferior vena cava (IVC) complicated by extensive bilateral deep venous thrombosis (DVT) with significant oedema following a long-distance road trip. Initially the patient failed treatment with standard anticoagulation therapy with enoxaparin and warfarin. However, he has responded to the new oral antifactor-Xa anticoagulant (rivaroxaban).

Three-year follow-up of a randomised clinical trial of intravenous versus oral iron for anaemia in pregnancy.

Background: To date, there are no data available concerning the impact of iron therapy on the long-term well-being and health-related quality of life (HRQoL) in pregnancy.

Objective: To assess the long-term effect of iron therapy on HRQoL in pregnancy.

Design: This is a follow-up study conducted between January 2010 and January 2011 of an earlier randomised open-label clinical trial of intravenous and oral iron versus oral iron for pregnancy-related iron deficiency anaemia.

Iron deficiency anaemia in pregnancy and postpartum: pathophysiology and effect of oral versus intravenous iron therapy.

Nutritional iron-deficiency anaemia (IDA) is the most common disorder in the world, affecting more than two billion people. The World Health Organization's global database on anaemia has estimated a prevalence of 14% based on a regression-based analysis. Recent data show that the prevalence of IDA in pregnant women in industrialized countries is 17.

D-Dimer levels at different stages of pregnancy in Australian women: a single centre study using two different immunoturbidimetric assays.

Background: To date there is minimal data available on D-Dimer levels at different stages of pregnancy.

Patients And Methods: We prospectively measured D-Dimer levels in 632 consecutive pregnant women from March 2007 to January 2009. The median age of the participants was 31 years (range; 18-42) with a median weight of 78 kilograms (range; 46-137).

An unusual presentation of desmoplastic small round cell tumour of the abdomen: morphological, immunohistochemical, ultrastructural, and molecular studies.

Desmoplastic small round cell tumour (DSRCT) is an aggressive and a rare neoplasm. We report on a 34-year-old male who had abdominal discomfort with a large intraperitoneal mass. Histological examination of the tumour biopsy revealed sheets of small round cells.
