Neurologic Sequelae after spinal anesthesia are extrenely rare, due in part to use of prepackaged and sterile kits and the small doses of local anesthectics employed. We have experienced 42 years old healthy male developed cental nervous system toxicity due to injection of wrong substance into subarachnoid space. And the patient recovered 3 days later with mild pulmonary edema and about 72 hour anterograde amnesia after symptomatic treatment.

BACKGROUNDS/AIMS: Vitamin K may plays a role in controlling hepatocellular carcinoma (HCC) cell growth. In this study, we intended to present 5-year experience of 72 patients receiving oral vitamin K with or without sorafenib. Its end-point was to evaluate the safety of combination therapy using sorafenib and vitamin K. METHODS: An interim analysis was performed as a single-arm cross-sectional study, including 72 HCC patients who underwent liver resection or transplantation and administered oral vitamin K2 alone (n=47) or with sorafenib (n=25). RESULTS: In all patients, administration of vitamin K2 analog 45 mg/day did not show any noticeable adverse side-effect during vitamin K therapy of 23.3+/-10.6 months, except for one patient who experienced skin rash at the third day of vitamin K therapy. In 25 patients receiving sorafenib and vitamin K for 6 months or longer, any noticeable adverse side-effect suspected of vitamin K origin was not identified yet. A small proportion of patients showed unexpectedly favorable anti-tumor effects after use of vitamin K with or without sorafenib. CONCLUSIONS: Because add-on of oral vitamin K did not increase the adverse side-effects of sorafenib, a combination therapy with these two agents appears to be worthy of further clinical trial with an expectation of synergistic therapeutic effects.

As a preceding study to apply recombinant BMP-7 gene to the human, we investigated bone formation in immunodeficient mice by using tissue engineering and gene transplatation. Human dermal fibroblasts were transduced with AdBMP-7 and cultured with type I collagen solution to form collagen sponge. The collagen sponge containing AdBMP-7 transduced fibroblasts was transplanted into hypodermis of the mice and osteogenesis in the spongy was investigated by histochemical, electronmicroscopic, and radiologic methods at 1, 2, 4, 6, and 8 weeks. At one week after transplantation, there were fluent cells infiltration around the collagen sponge and capsular structure was formed with fibers arranged in concentric circles. New vessel formation was observed in the capsule and subcapsular area of the sponge, but there were nucleus condensation and obscure cell boundary in the cells of the central region. Lacuna containing eosinophilic structures were observed in the capsular structure at two weeks. This structures were enlarged with time and were confirmed to be bone tissue by showing positive reaction for Von Kossa stain. Cartilaginous structure was not observed in light microscopic level, but a few chondroblasts were observed in pericapsular area in electron microscopic observation. After 6 weeks, radiopaque shadows were observed at the region of transplantation. Cortical bone was formed in periphery of the sponge while marrow like structure was observed in central region; some trabecula bone, adipocytes, and well developed vessels. The percentage of bone formation in transplanted sponge at 1, 2, 4, 6, and 8 weeks were 0, 63, 88, 100, and 100% (n = 8), respectively. From these results, bone formation by BMP-7 transduced human dermal fibroblasts using collagen sponge scaffolds in immunodeficient mouse shows another potential way of human gene transplantation using recombinant BMP-7 adenovirus.
