Case Reports
A case where rocuronium was unable to achieve neuromuscular block immediately after sugammadex administration.
We present a case where immediate muscle relaxation was needed following sugammadex administration. A 72 year-old female underwent surgery for a cerebral artery aneurysm. Upon conclusion of the operation sugammadex (9.3 mg/kg) was administered and the patient was noted to have left hemiplegia. ⋯ Although TOF monitoring was not utilized in this case and assessing residual muscular block was difficult, spontaneous respirations continued and breathing had to be controlled with sevoflurane and remifentanil. Sugammadex is a potent reversal agent for rocuronium-induced neuromuscular block, however, certain situations require immediate neuromuscular blockade following sugammadex. In this case, rocuronium was unable to induce neuromuscular blockade immediately after sugammadex and that higher concentrations were necessary in addition to intravenous analgesics and inhaled anesthetics.

Case Reports
Anterior thoracolumbar reconstruction surgery for late collapse following vertebroplasty: report of three cases.
Although vertebroplasty (VP) using polymethylmethacrylate (PMMA) is thought to be an effective procedure for osteoporotic vertebral compression fractures, several complications have been reported. In this paper, we present three patients who developed local kyphotic deformity as a result of late collapse of the cemented vertebrae. ⋯ In conclusion, VP is thought to be an effective and minimal invasive technique to treat osteoporotic compression fractures in older patients. Once collapse or nonunion of the treated vertebral body occurs, however, removal of the cement and anterior reconstruction may be required to realign of the affected segments and reconstruct the spine.

Clinical trials leading to drug approval (registration trials) play a central role in the drug development process. Since the introduction of the Good Clinical Practice (GCP) standard in 1997, the Japanese infrastructure for registration trials has improved. The contribution of support staff, including clinical research coordinators (CRCs), to clinical trials is now widely recognized in Japan. ⋯ This survey revealed that the group discussion in the present symposium appears to be valuable for participants, using overall satisfaction as a surrogate. Based on the information obtained in the present study, further development of the clinical trial infrastructure, including training opportunities and career development for support staff, is required. Due to the limitations of this study, further analysis is warranted to determine the optimal strategy for training support staff.
