Background:
We aimed to evaluate whether composite blood biomarkers including aldo-keto reductase family 1 member B10 (AKR1B10) and cytokeratin 18 (CK-18; a nonalcoholic steatohepatitis [NASH] marker) have clinically applicable performance for the diagnosis of NASH, advanced liver fibrosis, and high-risk NASH (NASH+significant fibrosis).
Methods:
A total of 116 subjects including healthy control subjects and patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD) were analyzed to assess composite blood-based and imaging-based biomarkers either singly or in combination.
Results:
A composite blood biomarker comprised of AKR1B10, CK-18, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) showed excellent performance for the diagnosis of, NASH, advanced fibrosis, and high-risk NASH, with area under the receiver operating characteristic curve values of 0.934 (95% confidence interval [CI], 0.888 to 0.981), 0.902 (95% CI, 0.832 to 0.971), and 0.918 (95% CI, 0.862 to 0.974), respectively. However, the performance of this blood composite biomarker was inferior to that various magnetic resonance (MR)-based composite biomarkers, such as proton density fat fraction/MR elastography- liver stiffness measurement (MRE-LSM)/ALT/AST for NASH, MRE-LSM+fibrosis-4 index for advanced fibrosis, and the known MR imaging-AST (MAST) score for high-risk NASH.
Conclusion
Our blood composite biomarker can be useful to distinguish progressive forms of NAFLD as an initial noninvasive test when MR-based tools are not available.

Background:
Several noninvasive tools are available for the assessment of nonalcoholic fatty liver disease (NAFLD) including clinical and blood biomarkers, transient elastography (TE), and magnetic resonance imaging (MRI) techniques, such as proton density fat fraction (MRI-PDFF) and magnetic resonance elastography (MRE). In the present study, we aimed to evaluate whether magnetic resonance (MR)-based examinations better discriminate the pathophysiologic features and fibrosis progression in NAFLD than other noninvasive methods.
Methods:
A total of 133 subjects (31 healthy volunteers and 102 patients with NAFLD) were subjected to clinical and noninvasive NAFLD evaluation, with additional liver biopsy in some patients (n=54).
Results:
MRI-PDFF correlated far better with hepatic fat measured by MR spectroscopy (r=0.978, P<0.001) than with the TE controlled attenuation parameter (CAP) (r=0.727, P<0.001). In addition, MRI-PDFF showed stronger correlations with various pathophysiologic parameters for cellular injury, glucose and lipid metabolism, and inflammation, than the TE-CAP. The MRI-PDFF and TE-CAP cutoff levels associated with abnormal elevation of serum alanine aminotransferase were 9.9% and 270 dB/m, respectively. The MRE liver stiffness measurement (LSM) showed stronger correlations with liver enzymes, platelets, complement component 3, several clinical fibrosis scores, and the enhanced liver fibrosis (ELF) score than the TE-LSM. In an analysis of only biopsied patients, MRE performed better in discriminating advanced fibrosis with a cutoff value of 3.9 kPa than the TE (cutoff 8.1 kPa) and ELF test (cutoff 9.2 kPa).
Conclusion
Our results suggest that MRI-based assessment of NAFLD is the best non-invasive tool that captures the histologic, pathophysiologic and metabolic features of the disease.

PURPOSE: The purpose of this study was to analyze any effectiveness, advantages, and the procedure of an ultrasound-guided suprascapular nerve block via the proximal approach in patients suffering from shoulder pain. MATERIALS AND METHODS: A total of 51 patients treated with nerve block between November 2015 and November 2016 were analyzed. We identified the suprascapular nerve that branches off the superior trunk of the brachial plexus, and found the suprascapular nerve, which is located in the fascial layer between the inferior belly of the omohyoid muscle and the serratus anterior muscle. We then performed a nerve block. We evaluated the visual analogue scale (VAS) of pre- and post-nerve block, and the visualization of the nerve, depth from the skin to the nerve, angle of needle entry, as well as complications. Moreover, we measured the visualization of the nerve, depth from the skin to the nerve in a classic approach, and compared it with the proximal approach. RESULTS: There was significant improvement (p < 0.05) in the mean VAS, from 7.1 to 3.4, without any major complications. Compared with the classic approach, we were able to identify the suprascapular nerve much better (classic 25.5%/proximal 96.1%), and the mean distance from the skin to the nerve (classic 38 mm/proximal 12 mm) was significantly short (p < 0.05), and the mean angle of needle entry was 19 degrees in the proximal approach. CONCLUSION: In an ultrasound-guided suprascapular nerve block by proximal approach, the nerve and needle tip can be more easily identified, which increases accuracy; with a small amount of local anesthetic, more effective pain control can be achieved. Hence, this approach is an effective alternative pain control method for patients suffering from shoulder pain.

BACKGROUND: Laminoplasty is a surgical procedure frequently performed for cervical myelopathy. We investigated correlations between changes in the anteroposterior diameter (APD) of the spinal canal, spinal canal area (SCA), and laminar angle (LA) and clinical outcomes of laminoplasty. METHODS: Of the 204 cervical myelopathy patients who underwent laminoplasty from July 2010 to May 2015, 49 patients who were evaluated with pre- and postoperative computed tomography of the cervical vertebrae were included. The average age of the patients was 60.4 years (range, 31 to 82 years), and the average duration of follow-up was 31.6 months (range, 9 to 68 months). Changes in the APD and SCA were measured at the middle of the vertebral body. Changes in LA were measured where both pedicles were clearly visible. Clinical outcomes were assessed using the Japanese Orthopaedic Association (JOA) score and visual analog scale score for pain preoperatively (1 day before surgery) and postoperatively (last outpatient visit) and examining postoperative complications. RESULTS: The APD showed an average of 54.7% increase from 11.5 to 17.8 mm. The SCA showed an average of 57.7% increase from 225.9 to 356.3 mm². The LA increased from 34.2° preoperatively to 71.9° postoperatively. The JOA score increased from an average of 9.1 preoperatively to 13.4 postoperatively. Three patients were found to have hinge fractures during surgery. Postoperative complications, including two cases of C5 palsy, were recorded. The correlation coefficient between the LA change and JOA score improvement was −0.449 (p < 0.05). Patients with a < 33° (25%) increase in the LA showed the most significant clinical improvement. CONCLUSIONS: Patients with a < 33° (25%) change in the LA after laminoplasty with a titanium miniplate showed the most significant clinical improvement. Thus, LA changes can be useful in predicting the clinical outcome of laminoplasty.

PURPOSE: The purpose of this study is to report on the result of repairing Achilles tendon using absorbable suture under nerve block. MATERIALS AND METHODS: We retrospectively reviewed 20 patients with acute Achilles tendon rupture who were followed up for at least six months after the operation. We repaired Achilles tendon using two absorbable sutures using the Krackow technique for the proximal stump and the Kessler technique for the distal stump. A programmed postoperative management including non-weight bearing with a short leg cast for four weeks after the operation was applied for all patients. We evaluated clinical results using American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) for satisfaction, range of motion of ankle, functional recovery rate, and the starting time of single heel raise. RESULTS: The mean VAS score for satisfaction and AOFAS score was 9.2 and 93.0, respectively. The affected ankle showed a mean dorsiflexion rate of 90% and plantar-flexion rate of 94% compared to the uninjured side. The single heel raise could start at a mean of 3.5 months after the operation. CONCLUSION: Treatment of Achilles tendon rupture with absorbable suture material using the hybrid suture technique of proximal Krackow and distal Kessler showed sufficient stability and minimal chronic inflammatory reaction.

PURPOSE: The purpose of this study is to compare and analyze the clinical results according to the complications occurring after laminoplasty for cervical myelopathy patients. MATERIALS AND METHODS: Among patients diagnosed as cervical myelopathy, 152 cases in which patients underwent cervical laminoplasty from March 2006 to March 2011 from Chungnam National University Hospital and had follow-up for at least two years were selected for the study, and the mean follow-up period was 39.7 months. The cases were divided into two groups; cases that underwent plate fixation for hinge fracture during cervical laminoplasty or showed postoperative spontaneous interlamina fusion were included in group A and cases that did not show such complications were included in group B. Clinical results were measured using visual analogue scale (VAS) score and Neck Disability Index (NDI) preoperatively, postoperatively, and on the final follow-up. RESULTS: Among 152 cases, 31 cases were included in group A and 121 cases in group B. Group A consisted of 11 cases of fixation due to intraoperative hinge fracture and 20 cases of postoperative spontaneous interlamina fusion. Mean preoperative VAS score was 7.52 in group A and 7.26 in group B, and mean postoperative VAS score was 2.87 in group A and 3.03 in group B. Mean NDI improved from 74.32% preoperatively to 43.84% postoperatively in group A and 75.74% preoperatively to 45.36% postoperatively in group B. In both groups, on postoperative follow-up, no significant difference of VAS score and NDI was found and both showed improvement compared to before surgery. CONCLUSION: The clinical results of cases that underwent plate fixation for hinge fracture that occurred during cervical laminoplasty and postoperative spontaneous interlamina fusion showed no significant difference compared to cases that did not show any complications.

PURPOSE: Conventional laparoscopic appendectomy is performed using three ports, and single-port appendectomy is an attractive alternative in order to improve cosmesis. The aim of this study was to compare pain after transumbilical single-port laparoscopic appendectomy (SA) with pain after conventional three-port laparoscopic appendectomy (TA). METHODS: From April to September 2011, 50 consecutive patients underwent laparoscopic appendectomy for simple appendicitis without gangrene or perforation. Patients who had undergone appendectomy with a drainage procedure were excluded. The type of surgery was chosen based on patient preference after written informed consent was obtained. The primary endpoint was postoperative pain evaluated by the visual analogue scale score and postoperative analgesic use. Operative time, recovery of bowel function, and length of hospital stay were secondary outcome measures. RESULTS: SA using a SILS port (Covidien) was performed in 17 patients. The other 33 patients underwent TA. Pain scores in the 24 hours after surgery were higher in patients who underwent SA (P = 0.009). The change in postoperative pain score over time was significantly different between the two groups (P = 0.021). SA patients received more total doses of analgesics (nonsteroidal anti-inflammatory drugs) in the 24 hours following surgery, but the difference was not statistically significant. The median operative time was longer for SA (P < 0.001). CONCLUSION: Laparoscopic surgeons should be concerned about longer operation times and higher immediate postoperative pain scores in patients who undergo SA.

BACKGROUND AND OBJECTIVES: Ramipril and candesartan have decreased the incidence of new onset diabetes in large scale randomized clinical studies. Because ramipril and candesartan have distinct mechanisms of action in the renin angiotensin aldosterone system, we hypothesized that combination therapy would have additive beneficial metabolic effects in patients with hypertension. SUBJECTS AND METHODS: Thirty-four patients were given ramipril 10 mg and placebo, ramipril 10 mg and candesartan 16 mg, or candesartan 16 mg and placebo daily in a randomized, double-blind, placebo-controlled cross-over trial with three treatment arms and two washout periods (each being 2 months). RESULTS: Ramipril, combination therapy or candesartan significantly increased the plasma adiponectin levels relative to the baseline measurements by 17+/-6% (p=0.038), 25+/-5% (p<0.001), and 14+/-6% (p=0.016), respectively. Combination therapy significantly increased the plasma adiponectin levels more than either ramipril or candesartan alone (p=0.020 by ANOVA). Only combination therapy significantly increased the QUICKI level relative to the baseline measurements (p=0.002). There were no significant correlations between these changes of the metabolic parameters and reduction of the systolic blood pressure (-0.288< or =r< or =0.284) and reduction of the diastolic blood pressure (-0.282< or =r< or =0.190). On multivariate analysis, only the change of adiponectin levels was an independent predictor of the changes in the QUICKI levels (beta=1.549, p=0.040) following combination therapy. CONCLUSION: Ramipril in combination with candesartan increases the plasma adiponectin levels to a greater extent than monotherapy with either drug alone. Only combination therapy significantly improves insulin sensitivity relative to the baseline measurements. The only predictor for the improvement of insulin sensitivity is the increase of plasma adiponectin levels by combination therapy.

PURPOSE: We conducted this study to assess the effect of oral application of bovine colostrum on the plasma endotoxin and TNF-alpha following the abdominal surgery. METHODS: 46 patients who underwent the abdominal surgery were evenly enrolled in a prospective, randomized, double blind and placebo-controlled study. The patients were preoperatively managed by oral application of 20 g of a bovine colostrums or placebo (nonfat dried milk) per a day for 3 days. In both groups, endotoxin was sequentially determined pre-, intra- and postoperatively by a modified limulus amebocyte lysate test. TNF-alpha and CRP were also measured. The clinical course was followed and compared in both groups. RESULTS: The colostrum group showed significantly lower level of endotoxin and TNF-alpha compared to the placebo group. CRP did not differ in both groups. Clinical event did not occur in both group until the discharge. Colostrum group tends to have a lower incidence of fever and leukocytosis without statistic significance. CONCLUSION: Prophylactic preoperative oral application of bovine colostrum lower the plasma level of perioperative endotoxin and TNF-alpha. Further studies were needed for the relation of clinical effect and preoperative oral application of bovine colostrum.
