    Research paper (journal)  

    There are some reports investigating the cause of death by examining the contents of the stomach and duodenum using postmortem computed tomography, but most of these have been based on radiopaque contents. Here, we report a case of suicide after ingesting a large amount of benzine. Although the gastric contents were radiolucent, the characteristic postmortem computed tomography imaging findings helped to determine the cause of death.

  • DECREASED EXPRESSION OF BOTH A AND B BLOOD ANTIGENS IN A PATIENT WITH MYELODYSPLASTIC SYNDROME

    <p>A man in his 20s was diagnosed with pyoderma gangrenosum and underwent emergency debridement. He had no history of a hematological disease, transfusion, or hematopoietic stem cell transplantation. ABO blood group typing results showed mixed field agglutination with both A and B blood antigens. Due to the possible association between hematological disease and pyoderma gangrenosum, bone marrow aspiration was performed and he was diagnosed with myelodysplastic syndrome with multilineage dysplasia (MDS-MLD) with chromosome 8 trisomy.</p><p>Serological tests, flow cytometric analysis, and genetic test precluded the possibility of hereditary ABO subgroup and blood chimerism, suggesting that his blood antigen expression was decreased due to MDS-MLD.</p><p>In turn, decreased A and B antigen expression and diagnosis of pyoderma gangrenosum allowed the diagnosis of MDS-MLD before he had overt abnormal hematological values.</p><p>For patients with decreased expression of both A and B blood antigens, the possibility of hematological disease should be kept in mind.</p>
