Potential role of comprehensive dental care in preventing medication related osteonecrosis of the jaw (MRONJ): a single centre study.

Objective: Medication-related osteonecrosis of the jaw bones (MRONJ) is a well-known complication of antiresorptive and antiangiogenic drugs. Since the first report, more occurrences of MRONJ have been described worldwide. Dental extraction has been described by many studies as one of the risk factors for MRONJ.

Inequality in Drug Utilization among Chronic Myeloid Leukaemia Patients in Malaysia: A Cost-Utility Analysis.

Background: The burden of chronic myeloid leukaemia (CML) is increasing due to longer patient survival, better life expectancy of the general population, and increasing drug prices. Funding is one of the main concerns in the choice of CML medication used worldwide; thus, patient assistance programmes were introduced to ensure accessibility to affordable treatment. In this study, we evaluated CML drug distribution inequality in Malaysia through patient assistance programmes, using pharmaco-economics methods to evaluate CML treatment from the care provider's perspective.

Clinical Epidemiology, Treatment Outcome and Mortality Rate of Newly Diagnosed Immune Thrombocytopenia in Adult Multicentre Study in Malaysia.

Background: Immune thrombocytopenia (ITP) is well characterized in Western, European and other Asia-Pacific countries. Nevertheless, the clinical epidemiology, treatment pattern and disease outcome of ITP in Malaysia are still limited and not well known.

Objective: This study aimed to describe the clinical epidemiology, treatment outcome and mortality of ITP patients in haematology tertiary multicentre in Malaysia.

Clinical Management of Thrombotic Antiphospholipid Syndrome.

Thrombotic manifestations of antiphospholipid syndrome are often a therapeutic dilemma and challenge. Despite our increasing knowledge of this relatively new disease, many issues remain widely unknown and controversial. In this review, we summarise the latest literature and guidelines on the management of thrombotic antiphospholipid syndrome.

Rare but Potentially Fatal Presentations of Diffuse Large B-cell Lymphoma: Leukemic Phase or Hemophagocytic Syndrome in Bone Marrow.

Diffuse large B-cell lymphoma (DLBCL) is a type of non-Hodgkin Lymphoma commonly presenting as a solid tumor either by nodal or extra-nodal manifestations. Here we describe two atypical presentations of lymphoma, finally resulting in the diagnosis of DLBCL. Case 1: A 53-year-old man with a previous history of nasopharyngeal carcinoma presented with a two-week history of B-symptoms and hyperleukocytosis.

Analysis of genetic variants in myeloproliferative neoplasms using a 22-gene next-generation sequencing panel.

Background: The Philadelphia (Ph)-negative myeloproliferative neoplasms (MPNs), namely essential thrombocythaemia (ET), polycythaemia vera (PV) and primary myelofibrosis (PMF), are a group of chronic clonal haematopoietic disorders that have the propensity to advance into bone marrow failure or acute myeloid leukaemia; often resulting in fatality. Although driver mutations have been identified in these MPNs, subtype-specific markers of the disease have yet to be discovered. Next-generation sequencing (NGS) technology can potentially improve the clinical management of MPNs by allowing for the simultaneous screening of many disease-associated genes.

Health-related quality of life using EQ-5D among chronic myeloid leukaemia patients in health centres in Klang Valley, Malaysia.

Chronic Myeloid Leukaemia (CML) responds well with the targeted therapy drugs, Tyrosine Kinase Inhibitors (TKI), that give potentially long-term disease control for the patients. The objective of this study was to determine the disease burden and factors influencing the health-related quality of life (HRQoL) and health status of CML patients in Klang Valley, Malaysia. CML patients were recruited from haematological outpatient clinics in health centres in Klang Valley, Malaysia.

Optic Nerve Infiltration in Systemic Metastatic Retinal Lymphoma (SMRL): Multimodal Imaging and Challenges in Diagnosis.

A 45-year-old man was diagnosed with diffuse large B-cell lymphoma stage IV which was confirmed by celiac lymph node biopsy. He subsequently completed six cycles of R-CHOP chemotherapy. Six months later, he presented with panuveitis OU with positive relative afferent pupillary defect OD.

Diffuse large B-cell lymphoma in Southeast Asian cohort: expression patterns of B-cell receptor (BCR) repertoire and its linkage with molecular subtypes and response to R-CHOP therapy.

Aims: Heightened B-cell receptor (BCR) activity in diffuse large B-cell lymphoma (DLBCL) is well established, and a subset of patients with relapsed DLBCL can benefit from BCR-targeted therapies. Universal outreach of such emerging therapies mandates forming a global landscape of BCR molecular signalling in DLBCL, including Southeast Asia.

Methods: 79 patients with DLBCL (nodal, 59% and extranodal, 41%) treated with rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) therapy were selected.

Pregnancy-related hemophagocytic lymphohistiocytosis associated with cytomegalovirus infection: A diagnostic and therapeutic challenge.

Objective: Hemophagocytic lymphohistiocytosis (HLH) is a disorder characterized by uncontrolled mature histiocyte proliferation, hemophagocytosis, and hypercytokinemia. We describe a previously healthy pregnant patient who presented in the third trimester of pregnancy with HLH.

Case Report: A 35-year-old woman presented at 38 weeks' gestation with pyrexia, jaundice, severe anemia, elevated liver enzymes, and lactate dehydrogenase suggestive of HELLP (hemolysis, elevated liver enzyme, low platelet) syndrome.

α-thalassemia-associated hydrops fetalis: A rare cause of thyrotoxic cardiomyopathy.

α°-thalassemia is a well-known cause of hydrops fetalis in South-East Asia and can be detected in utero. We report a very rare case of thyrotoxic cardiomyopathy associated with hyperplacentosis secondary to α°-thalassemia-associated hydrops fetalis. A 22-year-old primigravida with microcytic anemia presented at 27 weeks' gestation with pre-eclampsia, hyperthyroidism and cardiac failure.

Comparison of reduced-intensity and myeloablative conditioning regimens for allogeneic hematopoietic stem cell transplantation in patients with acute myeloid leukemia and acute lymphoblastic leukemia: a meta-analysis.

Currently, the indications to perform reduced-intensity conditioning allogeneic hematopoietic stem cell transplant (RIC-HCT) are based on data derived mainly from large registry and single-centre retrospective studies. Thus, at the present time, there is limited direct evidence supporting the current practice in selecting patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) for RIC versus myeloablative conditioning (MAC) transplants. To determine the relationship between dose intensity of conditioning regimen and survival outcomes after allografting in AML/ALL patients, we performed a meta-analysis of 23 clinical trials reported between 1990 and 2013 involving 15,258 adult patients that compare survival outcomes after RIC-HCT versus MAC-HCT.

Disseminated tuberculosis masquerading primary myelodysplastic syndrome.

Tuberculosis is notoriously known to be a great mimicker of other diseases and may cause various haematologic abnormalities, especially with marrow involvement. A 61-year-old man who presented with right empyema and pancytopenia was diagnosed to have disseminated tuberculosis supported by the presence of caseating granuloma with Langhan's giant cells in the marrow and demonstration of acid-fast bacilli in the pleural fluid. Trilineage dysplasia from marrow aspirate was initially attributed to be reactive to the infection.

Effects of preeclampsia on the yield of hematopoietic stem cells obtained from umbilical cord blood at delivery.

Aim: To compare the numbers of cord blood CD34(+) hematopoietic stem cells (HSC) between preeclampsia (PE) and control (non-PE) subjects and to determine the factors that may influence this observation.

Methods: Umbilical cord blood was collected from 28 PE and 19 non-PE subjects. Nucleated and CD34(+) cell counts were derived using the Trucount tube-based stem cell enumeration kit on BD FACSCalibur.
