Imaging modalities for multiple myeloma (MM) have evolved to enable earlier detection of disease. Furthermore, the diagnosis of MM requiring therapy has recently changed to include disease prior to bone destruction, specifically the detection of focal bone lesions. Focal lesions are early, abnormal areas in the bone marrow, which may signal the development of subsequent lytic lesions that typically occur within the next 18-24 months.

More than 80% of patients with MM display evidence of myeloma bone disease (MBD), characterised by the formation of osteolytic lesions throughout the axial and appendicular skeleton. MBD significantly increases the risk of skeletal-related events such as pathologic fracture, spinal cord compression and hypercalcaemia.

The symptoms of WM are protean, often follow an asymptomatic phase and may include complications related to the paraneoplastic effects of IgM paraprotein. The revised 2016 World Health Organization classification includes the MYD88 L265P mutation, which is seen in >90% of cases, within the diagnostic criteria for WM.
View Article and Find Full Text PDFOptions for treatment of elderly patients with multiple myeloma have expanded substantially following the development of immunomodulatory drugs (IMiD), proteasome inhibitors and with enhancement in safety of high-dose therapy and autologous stem cell transplant (HDT + ASCT). The recognition of biological heterogeneity among elderly patients has made delivery of therapy more challenging. An individualised approach to treatment selection is recommended in an era in which highly efficacious treatment options are available for transplant-ineligible patients.

Further improvements have been observed following the availability of immunomodulatory drugs (IMiD) such as thalidomide and lenalidomide, and the proteasome inhibitor, bortezomib. Here, we summarise the recommendations of the Medical Scientific Advisory Group to the Myeloma Foundation of Australia for patients considered suitable for HDT + ASCT as part of initial therapy.

This condition poses a unique management challenge due to the complexity of the clinical presentation and the narrow therapeutic window of available therapies. Improved appreciation of the need for risk stratification, standardised use of sensitive laboratory testing for monitoring disease response, vigilant supportive care and the availability of newer agents with more favourable toxicity profiles have contributed to the improvement in treatment-related mortality and overall survival seen over the past decade.
View Article and Find Full Text PDFAcquired hemophilia A (AH) is a rare and serious acquired bleeding disorder where prompt and correct diagnosis is crucial, and immune suppression is often required for factor VIII (FVIII) autoantibody eradication. The acquired FVIII deficiency usually manifests as bruises and bleeding, and treatment such as FVIII has limited efficacy because of the neutralizing FVIII inhibitor. Expensive bypassing agents such as recombinant activated factor VII (rFVIIa) may be required to treat clinically significant bleeding.

Patients And Methods: We retrospectively reviewed the medical records of all patients identified in our clinical database as having received CP as treatment for relapsed MM after ASCT at Princess Margaret Hospital between July 1998 and May 2004. The CP regimen consisted of oral cyclophosphamide at 500 mg once weekly and oral prednisone at 100 mg on alternate days.
Purpose: To determine whether primary drug resistance or rapid relapse explains the poor prognosis seen in t(4;14)-positive multiple myeloma (MM).
Patients And Methods: A total of 131 patients treated with high-dose therapy (HDT) were assessed, of whom 19 were t(4;14) positive. We examined the presentation features, chemotherapy responsiveness at presentation and to salvage therapies at relapse, and overall survival outcomes.
Although cutaneous leishmaniasis is occasionally seen in Australia in overseas travellers and migrants, visceral leishmaniasis has been reported rarely and only in people who were immunocompromised. We describe an 18-year-old immunocompetent man who presented with pancytopenia and a 2-week history of fever and lethargy a year after visiting the Greek Islands. Visceral leishmaniasis was diagnosed after a bone marrow biopsy showed protozoa, and the patient responded well to treatment with liposomal amphotericin.
