OBJECTIVE:
To explore the effects of aerobic exercise combined with huwentoxin-I (HWTX-I)-mediated Keap1-Nrf2-ARE pathway on phase II detoxification enzymes HO-1 and NQO1 and their protective effects against obstructive jaundice (OJ)-induced central nervous system injury in mice.
METHODS:
50 male KM mice were randomly divided into blank group (GO), model group (M), aerobic exercise group (T), HWTX-I group (H), and aerobic exercise combined with HWTX-I group (TH). Mouse models of OJ were established with surgical suture for 72 h in the mice in all the groups except for the blank control group. The mice received interventions by aerobic exercise and tail vein injection of HWTX-I (0.05 μg/g) and were assessed by behavioral observation, Clark's neurological function scores, enzyme-linked immunosorbent assay (ELISA), brain tissue Nissl staining, hippocampal tissue Western blotting, and liver tissue mRNA expression profiling and sequencing.
RESULTS:
The mice in group M had obvious jaundice symptoms after the operation with significantly increased Clark's neurological score ( < 0.01). Compared with those in group M, the mice in group T, group H, and group TH showed significantly decreased serum levels of ALT, AST, TBIL, and TBA ( < 0.01) with increased contents of 5-HT and BDNF and decreased contents of S100B and NSE in the hippocampus ( < 0.01). Synergistic effects between aerobic exercise and HWTX-I were noted on the above parameters except for the liver function indicators. Interventions with aerobic exercise and HWTX-I, alone or in combination, obviously lessened pathologies in the brain tissue induced by OJ, and the combined treatment produced the strongest effect. The treatment also increased the expression levels of Nrf2, HO-1, and NQO1 mRNA and protein in brain tissues ( < 0.01 or 0.05) with a synergistic effect between aerobic exercise and HWTX-I. Illumina high-throughput sequencing showed that the differentially expressed factors participated mainly in such neural regulatory pathways as neuroactive ligand-receptor interaction, GABAergic synapses, dopaminergic synapses, synaptic vesicle circulation, and axon guidance, involving tissue cell neuronal signal transduction, apoptosis inhibition, immune response, and toxicity. Aerobic exercise and HWTX-I synergistically increased the accumulation of the signal pathways related with neuron damage repair and proliferation.
CONCLUSIONS
Aerobic exercise combined with HWTX-I can up-regulate the expression of phase Ⅱ detoxification enzymes HO-1 and NQO1 through the Keap1-Nrf2-ARE pathway to protect the central nervous system against OJ-induced damage in mice.

Chronic postsurgical pain (CPSP) is an unwanted adverse event in any operation. It leads to functional limitations and psychological trauma for patients, and leaves the operative team with feelings of failure and humiliation. Therefore, it is crucial that preventive strategies for CPSP are considered in high-risk operations. Various techniques have been implemented to reduce the risk with variable success. Identifying the risk factors for each patient and applying a timely preventive strategy may help patients avoid the distress of chronic pain. The preventive strategies include modification of the surgical technique, good pain control throughout the perioperative period, and preoperative psychological intervention focusing on the psychosocial and cognitive risk factors. Appropriate management of CPSP patients is also necessary to reduce their suffering. CPSP usually has a neuropathic pain component; therefore, the current recommendations are based on data on chronic neuropathic pain. Hence, voltage-dependent calcium channel antagonists, antidepressants, topical lidocaine and topical capsaicin are the main pharmacological treatments. Paracetamol, NSAIDs and weak opioids can be used according to symptom severity, but strong opioids should be used with great caution and are not recommended. Other drugs that may be helpful are ketamine, clonidine, and intravenous lidocaine infusion. For patients with failed pharmacological treatment, consideration should be given to pain interventions; examples include transcutaneous electrical nerve stimulation, botulinum toxin injections, pulsed radiofrequency, nerve blocks, nerve ablation, neuromodulation and surgical management. Physical therapy, cognitive behavioral therapy and lifestyle modifications are also useful for relieving the pain and distress experienced by CPSP patients.

PURPOSE: The severity and mortality of motorcycle accidents are higher than those of other traffic accidents. The majority of risk factors for injury severity identified in previous studies are difficult to apply. This study attempted to identify the clinically useful risk factors for predicting severely injured patients presenting to the emergency department after a motorcycle accident. METHODS: Motorcycle accident patients who visited a Level I trauma center from October 2015 to March 2017 were analyzed. The patients were classified as the severely injured group (Injury Severity Score, ISS≥16) and non-severely injured group (ISS<16). RESULTS: A total of 271 patients were analyzed; 135 (49.8%) patients were included in the severely injured group. Multiple logistic regression analysis was performed with the statistically significant factors between the two groups, including age, systolic blood pressure, heart rate, Glasgow coma scale, alcohol ingestion, and site of injury. The final risk factors predicting severely injured patients were as follows: age (adjusted odds ratio [aOR], 1.023; 95% confidence interval [CI], 1.005– 1.041; p=0.011), systolic blood pressure (aOR, 0.981; 95% CI, 0.970–0.993; p=0.002) and site of injury including abdomen (aOR, 5.785; 95% CI, 2.513–13.316; p<0.001), chest (aOR, 4.567; 95% CI, 2.274–9.173; p<0.001), head and neck (aOR, 5.762; 95% CI, 2.656–12.504; p<0.001), and face (aOR, 2.465; 95% CI, 1.229–4.943; p=0.011). CONCLUSION: Motorcycle accident patients should be assessed promptly for injury to the chest or abdomen by a careful physical examination and focused assessment with sonography for trauma.

PURPOSE: A secondary triage tool for pediatric trauma patients, “modified pediatric trauma score (mPTS)” was introduced to predict high risk trauma. METHODS: Pediatric trauma patients (≤15 years) presenting to the Pusan National University Hospital trauma center emergency department were analyzed retrospectively. The patients were classified into high risk and low risk groups. The high risk group was assigned an Injury Severity Score ≥12, death, intensive care unit admission, or urgent intervention (intubation, closed thoracostomy, emergency angiography and embolization, emergency surgery). The airway, blood pressure, fractures, level of consciousness, and external wounds were evaluated and the mPTS was calculated. RESULTS: One hundred seventy-seven patients were enrolled in this study. The mPTS had a sensitivity, specificity, positive predictive value, and negative predictive value of 88%, 54%, 60%, and 85%, respectively. Overtriage and undertriage was 39% and 14%, respectively. The mPTS missed 6 high risk patients and all 6 patients were abdominal injury patients. The mPTS was modified to include an abdominal physical examination and/or focused assessment with sonography for trauma. The newly developed scoring system was called the extended mPTS (E-mPTS). The E-mPTS had a sensitivity of 98% and negative predictive value of 98%. The safe level of overtriage (38%) was maintained. CONCLUSION: mPTS was applied to the patients and the undertriage rate was too high. The extended mPTS improved undertriage to 2% while maintaining the overtriage rate at a safe level. The E-mPTS is expected to have a resource saving effect when used as a pediatric trauma team activation standard.

Medial epicondylitis, also known as “golfer's elbow,” is a common overuse syndrome of the elbow and predominantly affects the origin of the common flexor tendon. We report two unique cases of medial epicondylitis complicated by chronic complete tear of the ulnar collateral ligament and common flexor tendon origin. Physical examination showed a focal huge swelling of medial epicondylar region of the dominant elbow and magnetic resonance imaging revealed complete tear of the ulnar collateral ligament and common flexor tendon and extravasation of intra-articular effusion. Satisfactory results were achieved with ulnar collateral ligament reconstruction and simultaneous repair of the common flexor tendon origin.

PURPOSE: Patients with multiple traumas often experience multiple fractures that are missed or overlooked, despite the use of imaging, careful history taking, and physical examinations. This study aimed to evaluate the usefulness of whole body bone scan (WBBS) for detecting missed bone injuries in patients with multiple traumas. METHODS: We evaluated 30 patients with multiple traumas who underwent WBBS at single tertiary referral center between March 2008 and February 2016. We assessed the association of patient demographics with WBBS uptake as a binomial outcome variable. RESULTS: There were no significant differences in patient demographics by WBBS. The mean injury severity score did not differ by WBBS (18.1 in the WBBS-negative group vs. 18.4 in the WBBS-positive group), and duration from admission to the evaluation of the WBBS was similar (5.4 days in both groups). The most common uptake site in the WBBS was the ribs (n=7), followed by the tibia (n=3), skull (n=2), ankle (n=1), and sternum (n=1). None of the missed injuries required further treatment, such as manual reduction or surgery. CONCLUSION: WBBS was useful for detecting missed bone injuries in patients with multiple trauma.

We report a 57-year-old man with bilateral cranial nerve IX and X palsies who presented with severe dysphagia. After a mild head injury, the patient complained of difficult swallowing. Physical examination revealed normal tongue motion and no uvular deviation. Cervical X-ray findings were negative, but a brain computed tomography revealed a skull fracture involving bilateral jugular foramen. Laryngoscopy indicated bilateral vocal cord palsy. In a videofluoroscopic swallowing study, food residue remained in the vallecula and pyriform sinus, and there was reduced motion of the pharynx and larynx. Electromyography confirmed bilateral superior and recurrent laryngeal neuropathy.

A 31-year-old male motorcyclist presented with prepatellar swelling of the left knee after a collision with a car. Magnetic resonance imaging of the knee showed no bony or ligamentous injury to the knee. Instead, a well-defined, thin-walled, T2-weighted hyperintense fluid collection with internal septations was identified in a prefascial location overlying the left patella and patellar tendon. The findings were in keeping with those of a Morel-Lavallée lesion, a closed internal degloving injury. Morel-Lavallée lesions are occasionally encountered after a blunt soft-tissue trauma. The presentation and imaging features are discussed.

9.Rapid Growing Eosinophilic Granuloma in Skull after Minor Trauma.
Korean Journal of Neurotrauma 2015;11(1):22-25
The authors present a case of rapidly progressing eosinophilic granuloma (EG) of the skull without hemorrhage after minor trauma. A 6-year-old boy presented with a soft mass on the midline of his forehead. He had a surgery for EG 19 months ago. One month earlier, computed tomography (CT) and bone scans were performed to evaluate the possible recurrence of EG, and there was no evidence of recurrence in CT. However, a slightly increased uptake in the bone scan was noted on the midline of the forehead. A rapid growing mass developed in a new spot after a minor trauma 7 days before the patient arrived at the clinic. His physical examination was unremarkable, except for a non-tender, soft, and immobile mass. A plain skull X-ray and CT showed a lytic bony defect on the midline of the frontal bone. Magnetic resonance imaging showed a 1.4 cm sized enhancing mass. Surgical resection and cranioplasty were done. The role of trauma in the development of EG is unclear. However, our case suggests that minor trauma is an aggravating factor for EG formation. Careful observation with regular follow-up is necessary in patients with EG after minor trauma.

Diagnosis of traumatic arteriovenous fistula (AVF) is usually delayed because it takes time to be enlarged enough to emerge radiologically or because symptoms occur a few months after the trauma. A 56-year-old woman presented with a newly developed tinnitus immediately after a head trauma. Pulsatile high-frequency tinnitus was heard also by examiner and recorded using a transcanal microphone. Angiography revealed an intracranial dural AVF fed by the middle meningeal artery, draining the superior sagittal sinus on the affected side. After percutaneous transarterial embolization, tinnitus successfully disappeared. The clinical presentation, radiologic and angiographic features, and management are discussed. To our knowledge, this is the first reported case of pulsatile tinnitus caused by AVF developed immediately after a trauma. We emphasize that precise physical examination, laboratory tests, and appropriate radiographic imaging are essential for accurate diagnosis and treatment when a patient presents with pulsatile tinnitus, especially after a head trauma.
