There is an increasing demand for platelet transfusions due to intensive chemotherapy and blood stem cell or bone marrow transplantation for the treatment of hematologic and oncologic diseases. There has been a long-lasting debate over whether the traditional threshold for prophylactic platelet transfusion of 20,000/microl is really necessary to prevent hemorrhagic complications. During the las...

Adolescents and young adults (AYA) with cancer have been designated as a vulnerable population by the National Cancer Institute. This group, defined by the ages of 16-39 years, has not enjoyed the same survival improvements over the past several decades as older and younger cohorts. Several barriers prevent the optimal delivery of oncologic care in this subpopulation. This review will describe ...

BACKGROUND AND OBJECTIVE The prevalence and pathogenic role of human herpesvirus 6 (HHV-6) in various benign and malignant hematologic diseases remain largely unknown. The aim of this study was to search for a possible involvement of HHV-6 in the pathogenesis of hematologic diseases. DESIGN AND METHODS The presence of HHV-6 DNA sequences was examined by polymerase chain reaction (PCR) in bone...

Because of recent advances in instrumentation, immunological reagents, and methods for measuring a variety of cell constituents and functions, there has been increasing interest in clinical applications of flow cytometry. Several commercially available flow cytometers and a growing list of monoclonal antibodies make it feasible for clinical laboratories to apply this technology for phenotyping ...

Occupational diseases may be defined only medically or scientifically, and even then, their definition is not simple. However, compensable occupational diseases involve the additional layer of legal systems and social welfare policies as well. Their multifaceted nature makes determining the work-relatedness of these diseases more complex. Korea has established standards for the recognition of o...

A variety of systemic and extra-abdominal diseases can cause symptoms within the abdominal cavity. Systemic and extra-abdominal diseases may include abdominal symptoms caused by several mechanisms. This article discusses the most important and common of these causes, namely the metabolic/endocrine causes, hematologic causes, inflammatory causes, infectious causes, functional causes, and the neu...

Dysplastic changes in erythroid precursors occur not only in patients with hematologic diseases, but also those with other diseases. Here, we report on a patient that presented with dysplastic changes in erythroid precursors due to lead poisoning from the intake of Chinese folk remedies.

Cytochrome P450 2J2 (CYP2J2) epoxygenase converts arachidonic acid to four regioisomeric epoxyeicosatrienoic acids (EETs) that exert multiple biological effects in the cardiovascular system and in various human solid cancers. However, it is unknown whether this enzyme is expressed or plays any role in malignant hematological diseases. In this study, we found strong and highly selective CYP2J2 e...
