This manuscript assesses the risks, benefits, and ethical concerns regarding the use of assisted reproductive techniques (ART) to create a new donor for stem cell transplantation. We address ethical literature, the medical and psychosocial impact on patient, donor, family, and medical caregivers, and the appropriate decision-making process. We conclude that the use of ART to create a stem cell donor can be ethically acceptable. The decision to conceive a donor has medical and psychosocial implications. The family is the appropriate decision-maker and must consider risks and benefits to all parties with input from medical caregivers.
Hemivertebra is a rare congenital spinal disorder where only one side of the vertebral body develops, leading to deformation of the spine, such as scoliosis or kyphosis. Previous reports suggest that the diagnosis may be based on antenatal sonographic examination after 14 weeks. We present the sonographic features of a fetus with solitary hemivertebra at 13 weeks' gestation confirmed by postmortem babygram, magnetic resonance imaging (MRI) and pathological examination. It shows that the condition may manifest in the first trimester of pregnancy.
We report on a fetal autopsy case in which a congenital cervical immature teratoma was diagnosed. A 24-year-old Japanese woman had carried a male fetus that was aborted because of a cervical tumor at 20 weeks 5 days of gestation. The cervical tumor weighed 93 g and measured 7.5x5.5x5 cm. The soft tumor was encapsulated by a fibrous layer, was solid with small cysts on the cut surface, and showed a brain-like appearance. The tumor was composed of neoplastic cells derived from the three germ cell layers: ectoderm, mesoderm, and endoderm. The cells showed both immature and mature features. Small areas of thyroid tissue were detected in the cervical tumor. The left lobe of the thyroid gland was not observed, but the right lobe of the thyroid gland was present laterally between the trachea and the esophagus. Therefore, we concluded that the cervical tumor had arisen in the left lobe of the thyroid gland rather than from the soft tissue of the neck.
