Dengue fever has rarely been reported as an etiology for aplastic anemia. An 8-year-old girl was admitted with fever, myalgia and petechiae. Dengue virus IgM antibodies were positive. She recovered completely, but her thrombocytopenia persisted. Six weeks later she became pancytopenic. A bone marrow aspirate and biopsy showed severe aplastic anemia. She was treated with antithymocytic immunoglobulin, methylprednisolone and cyclosporine. She became transfusion independent 6 months later. Dengue-virus induced aplastic anemia is a rare entity, but it must be identified early for better outcome. Immunosuppressive therapy can induce remission.

Hematologic complications are common in pregnancy and can significantly impact both maternal and fetal health. Recognizing and treating these complications can be challenging due to the limited evidence available to guide clinical consultants. Iron deficiency anemia is the most prevalent hematologic issue in pregnancy and often occurs due to increased maternal blood volume and the nutritional demands of the growing fetus.

The objective of this paper is to construct a follow-up cohort of medical x-ray workers and analyze the risk estimates of radiation-induced carcinogenic and noncarcinogenic diseases induced by chronic low-dose ionizing radiation exposure in the follow-up cohort. A fixed cohort study was used. A total of 159 medical x-ray workers working in radiology departments of hospitals in Gansu Province from 1950 to 1980 were selected as the radiology group, and 149 medical workers in internal medicine, surgery, and other departments who had not engaged in radiology work at the same hospital were selected as the control group.

Background: Thymoma is a rare mediastinal neoplasm originating from thymic epithelial cells, often associated with paraneoplastic syndromes. These syndromes can manifest as a range of autoimmune disorders, including myasthenia gravis, pure red cell aplasia, and aplastic anemia. Clinical trials involving the use of immune checkpoint inhibitors (ICIs) in thymoma have been complicated by a high incidence of immune-related adverse effects (irAEs).

After three cycles of AO therapy, she developed severe pancytopenia with hypoplastic bone marrow and was diagnosed with fulminant aplastic anemia (AA) due to neutropenia with no response to granulocyte colony-stimulating factor. One month after the onset of AA, she received HLA-haploidentical allogeneic hematopoietic stem cell transplantation (haplo-SCT) from a daughter using FluMelTBI (fludarabine 180 mg/m, melphalan 80 mg/m, total body irradiation 4 Gy) as the conditioning regimen and tacrolimus, mycophenolate mofetil, and post-transplant cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis.

Department of Clinical Microbiology, St. James Hospital, Dublin, Ireland.
Magnusiomyces capitatus is an environmental fungus found in soil, water, air, plants, and dairy products which may cause opportunistic infections in patients with haematological disorders resulting in high mortality rates. This series of the first reported cases in Ireland discusses investigation of two patients with underlying haematological disorders, hospitalised in the Irish National Adult Stem Cell Transplant Unit (NASCTU), who developed line-related fungaemias with M. capitatus within a three-month period.
