Case of acquired haemophilia a in Southeast Asia following COVID-19 vaccine.

Acquired haemophilia A (AHA) is a rare bleeding disorder with high morbidity and mortality, but it is eminently treatable if diagnosis and treatment are prompt. We report a case of AHA in Southeast Asia following the administration of the Pfizer-BioNTech COVID-19 vaccine. A man in his 80s developed multiple bruises 2 weeks after his first dose of the COVID-19 vaccine.

Cancer-Associated Thrombosis: A Clinical Scoping Review of the Risk Assessment Models Across Solid Tumours and Haematological Malignancies.

Cancer-associated thrombosis (CAT) is a leading cause of death in cancer patients receiving outpatient chemotherapy. The latest guidelines emphasize stratifying the patients in terms of CAT risks periodically. Multiple risk assessment models (RAMs) were developed to classify patients and guide thromboprophylaxis to high-risk patients.

Challenging lymphoid malignancy of primary central nervous system lymphoma: A case report.

Introduction: Primary central nervous lymphoma is an aggressive disease without evidence of systemic spread with an annual incidence of 7 cases per 1,000,000 people in the United States.

Case Presentation: A 68-year-old gentleman of Malay ethnicity presented with left sided weakness associated with reduced sensation for one month. The patient was healthy and denied any constitutional symptoms, joint pains, rash or seizures.

Abdominal Lymphocyte-Depleted Hodgkin Lymphoma: A Rare Presentation.

Background: Hodgkin lymphoma (HL) is a type of lymphoma that arises from the B lymphocytes. The four main subtypes of HL are the nodular sclerosing, mixed cellularity, lymphocyte rich and the lymphocyte depleted. Nodular sclerosis subtype accounts for majority of all classical HL, whereas lymphocytic depletion type accounts for less than 1%.

Post-transplant lymphoproliferative disorder presenting as T-prolymphocytic leukemia: a case report.

Introduction: Post-transplant lymphoproliferative disorder is a serious disorder which occurs post hematopoietic stem cell transplant or solid organ transplantation. T-prolymphocytic leukemia is a T cell type monomorphic post-transplant lymphoproliferative disorder which accounts for only 2% of all mature lymphocytic leukemias in adults over the age of 30.

Case Presentation: A 59-year-old man of Chinese ethnicity presented to our hematology unit with headache, lethargy, and exertional dyspnea for the past 1 month.

A randomized double blind control trial comparing filgrastim and pegfilgrastim in cyclophosphamide peripheral blood hematopoietic stem cell mobilization.

There are few randomized trials comparing filgrastim and pegfilgrastim in peripheral blood stem cell mobilization (PBSCM). None of the trials studied the effects of the timing of pegfilgrastim administration on the outcomes of mobilization. We conducted a randomized triple blind control trial comparing the outcomes of filgrastim 5 µg/kg daily from day 3 onwards, 'early' pegfilgrastim 6 mg on day 3 and 'delayed' pegfilgrastim 6 mg on day 7 in cyclophosphamide PBSCM in patients with no previous history of mobilization.
