Between 10% and 20% of cancer pain patients fail to obtain adequate pain relief despite comprehensive medical management. The totally implantable programmable intrathecal drug delivery system (IDDS) is an attractive option for managing refractory cancer pain. In suitable patients, IDDS can provide reliable long-term analgesia without any permanent nerve or plexus destruction. IDDS can also allow patient care on an outpatient basis. In Taiwan, however, the experience of using IDDS in terminally ill cancer patients is very limited. ⋯ Intrathecal morphine delivery by using totally implantable programmable IDDS is an effective method to relieve refractory cancer pain.

Event-related potentials (ERPs) reflect higher cortical function and the P3 (P300) wave has been associated with various sensory, cognitive, and attention processes. The aims of this study were to understand the age-related change in ERPs in children between the ages of 6 and 13 years and to establish a normal reference value for Taiwanese children for use in future study of neurocognitive dysfunction in children. ⋯ The authors conclude that there exists an age-related change in ERP latency and amplitude during childhood. A negative correlation between ERP latencies and age and a positive correlation between ERP amplitude and age were found in this study. The authors emphasize that the auditory ERP value in children is not equal to that of adults. A normative auditory ERP value in children should be established prior to clinical application.

Umbilical cord blood is rich in primitive natural killer (NK) cells, which are activated by interleukin (IL)-12. It was previously reported that a novel IL-12 family cytokine, IL-27 comprised of EBI3 and p28, was elevated in maternal serum during normal pregnancy. Thus, we compared the immune regulatory functions of IL-27 and IL-12 on mononuclear cells derived from cord blood and adult peripheral blood. ⋯ From previous results, we summarize our current understanding of the augmentation of distinct regulation of NK cells by IL-27 and IL-12.
