Background: Pain on injection is a limitation with propofol use. The effect of the Valsalva maneuver on pain during propofol injection has not been studied. This maneuver reduces pain through the sinoaortic baroreceptor reflex arc and by distraction. We aimed to assess the efficacy of the Valsalva maneuver in reducing pain during propofol injection. Methods: Eighty American Society of Anesthesiologists class I adult patients undergoing general anesthesia were enrolled and divided into two groups of 40 each. Group I (Valsalva) patients blew into a sphygmomanometer tube raising the mercury column up to 30 mmHg for 20 seconds, while Group II (Control) patients did not. Anesthesia was induced with 1% propofol immediately afterwards. Pain was assessed on a 10-point visual analog scale (VAS), where 0 represented no pain, and 10, the worst imaginable pain, and a 4-point withdrawal response score, where 0 represented no pain, and 3, the worst imaginable pain. Scores were presented as median (interquartile range). Results: We analyzed the data of 70 patients. The incidence of pain was significantly lower in the Valsalva than in the control group (53% vs. 78%, P = 0.029). The withdrawal response score was significantly lower in the Valsalva group (1.00 [0.00-1.00] vs. 2.00 [2.00-3.00], P < 0.001). The VAS score was significantly lower in the Valsalva group (1.00 [0.00-4.00] vs. 7.00 [6.25-8.00], P < 0.001). Conclusions: A prior Valsalva maneuver is effective in attenuating injection pain due to propofol; it is advantageous in being a non-pharmacological, safe, easy, and time-effective technique.

Objectives : $18{\beta}$-Glycyrrhetinic acid (18betaGA) is an metabolite of glycyrrhizin in Glycyrrhiza (licorice). The present study investigated anti-inflammatory and anti-apoptosis effect of 18betaGA on the brain tissue of lipopolysaccharide (LPS)-treated C57BL/6 mice. Methods : 18betaGA was administered orally with low (30 mg/kg) and high (100 mg/kg) doses for 3 days prior to LPS (3 mg/kg) injection. Pro-inflammatory cytokines mRNA including tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin (IL)-$1{\beta}$, IL-6, and inflammatory enzyme cyclooxygenase-2 (COX-2) mRNA were measured in the cerebral cortex, hippocampus, and hypothalamus tissue using real-time polymerase chain reaction at 24 h after the LPS injection. Histological changes of Cornu ammonis area 1 (CA1) neurons, Bax, Bcl-2, and caspase-3 expression in the hippocampus was also evaluated by immunohistochemistry and Western blotting method. Results : 18betaGA significantly attenuated the up-regulation of TNF-${\alpha}$, IL-$1{\beta}$, IL-6 mRNA, and COX-2 mRNA expression in the brain tissues induced by the LPS injection. 18betaGA also significantly attenuated the reductions of the thickness of CA1 and the number of CA1 neurons. The up-regulation of Bax protein expression in the hippocampal tissue by the LPS injection was significantly attenuated, while the ratio of Bcl-2/Bax expression was increased by 18betaGA treatment. 18betaGA also significantly attenuated the up-regulation of Bax and caspase-3 expression in the CA1 of the hippocampus. Conclusion : This results indicate that 18betaGA has anti-inflammatory and anti-apoptosis effect under neuroinflammation induced by the LPS injection and suggest that 18betaGA may be a beneficial drug for various brain diseases accompanied with the brain tissue inflammation.

A vertebral cage is a hollow medical device which is used in spine forgery. By implanting the cage into the spine column, it is possible to restore disc and relieve pressure on the nerve roots. Most cages have been made of titanium alloys but they detract the biocompatibility. Currently PEEK (polyether ether ketone) if applied to various implants because it has good properties like heat resistance, chemical resistance, strength, and especially biocompatibility. A new shape of vertebral cage is designed and injection molding of PEEK is considered for production. Before injection molding of the cage, it is needed to evaluate process conditions and properties of the final product. Variables affecting the shrinkage of the cage are considered, e.g., injection time, packing pressure, mold temperature, and melt temperature. By using the numerical simula-tion program, MOLDFLOW, several cases are studied. Data files obtained by MOLDFLOW analysis are used for stress anal-ysis with ABAQUS, and shrinkage and residual stress fields are predicted. With these results, optimum process conditions are determined.

Soft tissue filler injection is the second most common nonsurgical cosmetic procedure. Despite the safety of fillers, as use has grown, so has the number of patients affected by adverse events. Ophthalmoplegia following cosmetic filler injection is a rare complication, mostly occurring after injection to the glabella, nasolabial fold, periorbital, and lateral nasal site. In all cases where ophthalmoplegia has been reported following fillers, patients have simultaneously experienced vision loss and other ocular symptoms. We report a case of isolated acute ophthalmoplegia following hyaluronic acid injection solely in the temple region. A 40-year-old woman, 3 hours after the procedure, presented to our hospital with left eye ophthalmoplegia, ptosis, and hypotropia. Treatment started with hyaluronidase, steroids, and anticoagulants. After 4 weeks, left eye ophthalmoplegia remained unchanged, and through a 10-week follow-up, all left ocular movements improved, and only mild hypotropia and ptosis persisted. This case report shows that ophthalmoplegia may also happen with temple region filler injections. We also review available prevention techniques and treatments to avoid such complications when performing soft tissue fillers for gaunt appearance correction.

Purpose: The aim of this study was to compare the efficacy and safety of band ligation and injection sclerotherapy in the endoscopic treatment of children with variceal bleeding. Methods: The study population included 55 children, all of whom were treated at the time of endoscopic diagnosis of esophageal varices at Asan Medical Center, Seoul, Korea, between January 1994 and January 2011. The primary outcomes included initial success rates and duration of hemostasis after endoscopic management (band ligation vs. injectionsclerotherapy). Results: The mean age was $6.7{\pm}5.2$ years and the mean follow-up time was $5.4{\pm}3.7$ years. The most common cause of esophageal varices was biliary atresia. Of 55 children with acute variceal bleeding, 39 had band ligation and 16 had injection sclerotherapy. No differences between groups were observed in terms of the size, location, and presence of red color sign. The success rates of band ligation and sclerotherapy in the control of acute bleeding episodes were 89.7% and 87.5%. The mean duration of hemostasis after endoscopic intervention was $13.2{\pm}25.1$ months. After one year, 19 of 39 patients (48.7%) treated with band ligation and 7 of 16 patients (43.8%) with injection sclerotherapy had experienced rebleeding episodes. Complications after the procedures were observed in 10.3% and 18.8% of children treated with band ligation and injection sclerotherapy. Conclusion: The results of our current study suggest that band ligation and injection sclerotherapy are equally efficient treatments for the control of acute variceal bleeding and prevention of rebleeding.
