Current issues on a standard for surrogate pregnancy procedures / 대한생식의학회지

While Korea does not have any legal statement on surrogacy, treatments are carried out in practice. As a result, every Institutional Review Board (IRB) of each fertility clinic faces an ethical predicament in reviewing each case. There is a need to arrange the institutions' own standards of surrogate pregnancy procedures before the establishment of national or professional regulation. This article examines the legal, social, and medical issues of surrogacy to help IRBs to judge their cases.

Two Cases of Trisomy 19 as a Sole Chromosomal Abnormality in Myeloid Disorders / 대한진단검사의학회지

Trisomy 19 is frequently encountered in cases of chronic myeloid leukemia (CML) as a secondary abnormality: however, trisomy 19 rarely occurs as a sole chromosomal abnormality and, to date, it has only been reported in 48 hematopoietic malignancies, 1 case of adenocarcinoma and 1 case of astrocytic tumor. Here, we report two additional cases of trisomy 19 as a sole karyotypic aberration in myeloid malignancies. One of these cases involved a 6-month-old male who was diagnosed with acute myeloid leukemia minimally differentiated. His karyotype was 47,XY,+19[20]. He expired 5 days after diagnosis. Another case occurred in an 80-yr-old female who had refractory anemia with excess blasts. Her karyotype was 47,XX,+19[16]/46,XX[4]. Four months later, her peripheral blood smears suggested that the disease had progressed, but she refused further evaluation. Based on a review of the existing literature and the results of this report, trisomy 19 not only as a secondary abnormality but also as a sole karyotypic aberration is strongly associated with myeloid disorder; however, it is not preferentially found in specific FAB subgroups of myelodysplasic syndrome or acute myeloid leukemia.
