ObjectiveTo compare the visibility and procedural parameters between a standard spinal needle and a new laser-etched needle (LEN) in real-time ultrasonography guided lumbar medial branch access in a phantom of the lumbosacral spine.MethodsWe conducted a prospective single-blinded observational study at a rehabilitation medicine center. A new model of LEN was manufactured with a standard 22-gauge spinal needle and a laser etching machine. Thirty-two inexperienced polyclinic medical students performed ultrasonography-guided lumbar medial branch access using both a standard spinal needle and a LEN with scanning protocol. The outcomes included needle visibility score, needle elapsed time, first-pass success rate, and number of needle sticks.ResultsThe LEN received significantly better visibility scores and shorter needle elapsed time compared to the standard spinal needle. First-pass success rate and the number of needle sticks were not significantly different between needles.ConclusionA new LEN is expected to offer better visibility and enable inexperienced users to perform an ultrasonography-guided lumbar medial branch block more quickly. However, further study of variables may be necessary for clinical application.

Objectives:To determine the prevalence of antimicrobial resistance in the normal rectal flora of patients undergoing transrectal ultrasonography-guided prostate biopsy in Korea. Methods: Between May 2010 and October 2010, rectal swabs were cultured from patients before transrectal ultrasonography-guided prostate biopsy in three tertiary referral centers of Jeonbuk Province, Korea. Rectal swabs were collected using cotton-tipped culture swabs in a standard collection system immediately before prostate biopsy. The swabs were cultured on eosin methylene blue and McConkey agar at 37°C. Antimicrobial sensitivity tests were carried out according to National Committee for Clinical Laboratory Standards guidelines. Results: Of the 160 patients who had a rectal swab taken before prostate biopsy, microorganisms were isolated in 125 patients. Escherichia coli was isolated from the rectal swabs of 95 patients. The mean age was 68.1 years, the median serum prostate specific antigen was 5.6 ng/mL and the mean prostate volume measured by transrectal ultrasonography was 43.8 mL. Of the E. coli, 33.7%, 29.1%, 26.7%, 23.3%, 12.8%, 9.3%, 5.8%, 1.2% and 0% were resistant to ampicillin, piperacillin, levofloxacin, trimethoprim sulfamethoxazole, gentamicin, cephalothin, cefotaxim, amikacin and meropenem, respectively. Conclusions: There is a high level of resistance to ciprofloxacin and ampicillin, and a very low level of resistance to amikacin in the E. coli in the bowel flora. The prevalence of resistance to ciprofloxacin in Korea is significantly higher than that reported in Western countries.

This study aims to develop an electronic moxibustion device for the quantification of moxibustion, which progresses a critical role in traditional oriental medicine as well as to assess the characteristics of heating. The assessment revealed that the proposed electronic moxibustion treatment device can reduce the time required for reaching the desired heat level and continue to provide heat consistently. Moreover, heat transmitted to the treated area was found to correspond to a heating pattern of the proposed electronic moxibustion device. It proved both quantitative control and safe treatment for the proposed electronic moxibustion device.

LDI has beneficial effects on the formation of fibroblast and collagen, and results in better wound healing.

This study aimed to find the effects of 12-week chiropractic and lumbar exercise program on the lumbar muscle strength and Cobb's angle in 16 adolescent students with scoliosis. The patients with scoliosis did not have neurological symptoms and surgery experience. Each group of eight subjects received chiropractic and lumbar exercises three times a week. Subjects' lumbar muscle strength measurement showed a statistically significant temporal difference in the chiropractic group (CG) and chiropractic with exercise group (EG) and had interaction effects. However, no significant difference was found between the two groups. Changes in the Cobb's angle in each group had a significant difference both temporally and between group in both CG and EG, and interaction effects were also significant. As suggested in this study, mutual application of exercise therapy program and chiropractic treatments was found to have a positive effect on lumbar muscle strength and Cobb's angle in patients with scoliosis.

Hepatic diseases, such as hepatonecrosis, hepatitis, and hepatocirrhosis, are associated with mitochondrial dysfunction and increased reactive oxygen species generation and inflammation, ultimately leading to liver failure. In this study, we examined if acupuncture at LR3 can affect mitochondria-related gene expression in a liver damage model of experimentally induced acute liver failure (ALF). ALF was induced by the intraperitoneal injection of D-galactosamine (D-GalN) in experimental rats, who then received either sham (ALF), manual acupuncture (MA), electroacupuncture (EA), or silymarin (PC, positive control) treatment. Liver tissues were extracted from experimental and untreated control rats for histopathological analysis and expression profiling of genes involved in mitochondrial function. Of the 168 mitochondria-related genes profiled, two genes belonging to the solute-carrier transporter family (Slc25a15 and Slc25a25) and Ndufb7 were upregulated. Gamma-glutamylcysteine synthetase was more downregulated in MA than ALF. Furthermore, MA reversed D-GalN-induced inflammatory cell infiltration, destruction of hepatic cell plates, and increase in the levels of the proinflammatory cytokine TNF-α. MA at LR3 can reduce the risk of D-GalN-induced ALF by inducing the expression of metabolic and inflammation-related genes and regulating proinflammatory factor production in hepatic mitochondria.
