PURPOSE: Patients with multiple traumas are at high risk of developing respiratory complications, including pneumonia and acute respiratory distress syndrome. Many pulmonary complications are associated with systemic inflammation and pulmonary neutrophilic infiltration. Leukotriene-receptor antagonists are anti-inflammatory and anti-oxidant drugs subsiding airway inflammation. The present study investigates the effectiveness of montelukast in reducing pulmonary complications among trauma patients. METHODS: This randomized, double-blind, placebo-control trial was conducted in patients with multiple blunt traumas and evidence of lung contusion detected via CT scan. We excluded patients if they met at least one of the following conditions: < 16 years old, history of cardiopulmonary diseases or positive history of montelukast-induced hypersensitivity reactions. Patients were allocated to the treatment (10 mg of montelukast) or placebo group using permuted block randomization method. The primary measured outcome was the volume of pulmonary contusion at the end of the trial. The secondary outcomes were intensive care unit and hospital length of stay, ventilation days, multi-organ failure, and the in-hospital mortality rate. RESULTS: In total, 65 eligible patients (treatment = 31, placebo = 34) were included for the final analysis. The treatment group had more pulmonary contusion volume (mean (SD), mm³) at the right (68726.97 (93656.54) vs. 59730.27 (76551.74)) and the left side (67501.71 (91514.04) vs. 46502.21 (80604.21)), higher initial C-reactive peptide level (12.16 (10.58) vs. 10.85 (17.87)) compared to the placebo group, but the differences were not statistically significant (p > 0.05). At the end of the study, the mean (SD) of pulmonary contusion volume (mm³) (right side = 116748.74 (361705.12), left side = 64522.03 (117266.17)) of the treatment group were comparable to that of the placebo group (right side = 40051.26 (64081.56), left side = 25929.12 (47417.13), p = 0.228 and 0.082, respectively). Moreover, both groups have statistically similar hospital (mean (SD), days) (10.87 (9.83) vs. 13.05 (10.12)) and intensive care unit length of stays (mean (SD), days) (7.16 (8.15) vs. 7.82 (7.48)). Of note, the frequency of the in-hospital complications (treatment vs. control group) including acute respiratory distress syndrome (12.9% vs. 8.8%, p = 0.71), pneumonia (19.4% vs. 17.6%, p = 0.85), multi-organ failure (12.9% vs. 17.6%, p = 0.58) and the mortality rate (22.6% vs. 14.7%, p = 0.41) were comparable between the groups. CONCLUSION Administrating montelukast has no preventive or therapeutic effects on lung contusion or its complications.

OBJECTIVES: To analyze the characteristics of thoracic aorta injury in road traffic accidents, to provide data reference for forensic identification. METHODS: The data of 27 traffic accident death cases with thoracic aorta injury were analyzed according to relevant parameters including sex, age, mode of transportation, and thoracic aorta injury. RESULTS: Aortic injury in traffic accidents was significantly more in males than females, and 74.1% cases were in the age range of 31-70 years. The most common mode of transportation was the motorcycle, followed by electric bike, most of which crashed with trucks. Most cases were accompanied by rib fractures and lung injuries. Thoracic aorta injury was the most common in ascending aorta, followed by aortic arch and thoracic aorta. Ascending aorta injury was most likely to occur in the range of 0-<1.6 cm from the aortic valve, while it was rare over 2.6 cm. Taking the aortic valve as the reference, the most common locations of injury were the anterior semilunar valve, followed by the right posterior semilunar valve and the left posterior semilunar valve. Thoracic aortic rupture occurred in 63.0% cases, and intima and media lacerations only occurred in 37.0% cases. A few deceased had aortic diseases. CONCLUSIONS The proximal part of the ascending aorta is prone to be injured because of the large external force of traffic accidents. The medical examiner should carefully examine the aortic injury in traffic accident deaths, and evaluate the relationship between the injury and the disease according to the condition and degree of aortic injury.

We reported two cases of jockeys who sustained fracture/dislocation of the mid-thoracic spine due to traumatic falls during horse racing. We examined the injury mechanism based upon the patients' diagnostic images and video footage of races, in which the accidents occurred. Admission imaging of patient 1 (a 42 years old male) revealed T5 burst fracture with bony retropulsion of 7 mm causing complete paralysis below T5/6. There existed 22° focal kyphosis at T5/6, anterolisthesis of T5 relative to T6, T5/6 disc herniation, cord edema and epidural hemorrhage from T4 through T6, and cord injury from C3 through C6. Admission imaging of patient 2 (a 23 years old male) revealed T4/5 fracture/dislocation causing incomplete paralysis below spinal level. There existed compression fractures at T5, T6, and T7; 4 mm anterior subluxation of T4 on T5; diffuse cord swelling from T3 through T5; comminuted fracture of the C1 right lateral mass; right frontal traumatic subarachnoid hemorrhage; and extensive diffuse axonal injury. The injuries were caused by high energy flexion-compression of the mid-thoracic spine with a flexed posture upon impact. Our results suggest that substantially greater cord compression occurred transiently during trauma as compared to that documented from admission imaging. Video footage of the accidents indicated that the spine buckled and failed due to abrupt pocketing and deceleration of the head, neck and shoulders upon impact with the ground combined with continued forward and downward momentum of the torso and lower extremities. While a similar mechanism is well known to cause fracture/dislocation of the cervical spine, it is less common and less understood for mid-thoracic spine injuries. Our study provides insight into the etiology of fracture/dislocation patterns of the mid-thoracic spine due to falls during horse racing.

Thoracic splenosis is the autotransplantation of splenic tissue in the left thoracic cavity as a result of a splenic injury. This rare pathology is usually asymptomatic and may be discovered on incidental imaging, but the diagnosis often requires invasive procedures such as surgery in order to eliminate a neoplasic origin. We report a rare symptomatic case of a 39-year-old man presenting with chest pain and multiple nodules revealed on a computed tomography scan. The patient underwent a surgical exploration and the pathological studies concluded to a thoracic splenosis. Indeed, the previous medical history of the patient revealed a left thoraco-abdominal traumatism during childhood. The aim of this paper is to emphasize that the diagnosis can now be performed using only imaging techniques such as technetium-99 sulfur colloid or labelled heat-denatured red blood cell scintigraphy to avoid unnecessary invasive procedures including thoracotomy.

PURPOSE: Injury continues to be an important cause of morbidity and mortality in both developed and developing countries. Globally, it is responsible for approximately 5.8 million deaths per year and 91% of these deaths occur in developing countries. Road traffic collision, suicides and homicides are the leading cause of traumatic deaths. Despite the fact that traumatic chest injury is being responsible for 10% of all trauma-related hospital admissions and 25% of trauma-related deaths across the world including in Ethiopia, only few published studies showed the burden of traumatic chest injury in Ethiopia. So, this study aims at assessing the characteristics and outcome of traumatic chest injury patients visited Tikur Anbesa Specialized Hospital (TASH) over one year period. METHODS: A single center based retrospective study was done. We collected data from patients' records to assess characteristics and outcome of traumatic chest injury at TASH over one year period. All patients diagnosed with traumatic chest injury and received treatment at the hospital from January 1 to December 31, 2016 regardless of its types and severity levels were included in the study. Patients with incomplete medical records for at least 20% of the study variables and without detailed medical history, or patients died before receiving any health care were excluded from the study. The collected data were cleaned and entered into Epidata version 3.1 and exported to SPSS Version 21.0 for analysis. Bivariate and multivariate logistic regression models were used to examine factors associated with outcome of traumatic chest injury patients. RESULTS: A total of 192 chest injury patients were included in the study and about one-fourth of chest injury victims were died during treatment period in TASH. Road traffic collision (RTC) was the leading cause of morbidity and mortality among traumatic chest injury victims. Age of the victims (adjusted odds ratio (AOR) 8.9, 95% confidence interval (CI) 1.51-53.24), time elapsed between the occurrence of traumatic chest injury and admission to health care facilities (AOR 4.6, 95% CI 1.19-18.00), length of stay in hospital (AOR 0.12, 95% CI 0.02-0.58), presence of multiple extra-thoracic injury (AOR 25, 95% CI 4.18-150.02) and development of complications (AOR 23, 95% CI 10-550) were factors associated with death among traumatic chest injury patients in this study. CONCLUSION RTC contributed for a considerable number of traumatic chest injuries in this study. Old age, delay in delivering the victim to health care facilities, length of stay in hospital, and development of atelectasis and pneumonia were associated with death among traumatic chest injury patients. Road safety interventions, establishment of organized pre-hospital services, and early recognition and prompt management of traumatic chest injury related complications are urgently needed to overcome the underlying problems in the study setting.

Duodenal injury is a serious abdominal organ injury. Duodenal fistula is one of the most serious complications in gastrointestinal surgery, which is concerned for its critical status, difficulty in treatment and high mortality. Thoracic and abdominal compound closed injury and a small part of open injury are common causes of duodenal injury. Iatrogenic or traumatic injury, malnutrition, cancer, tuberculosis, Crohn's disease etc. are common causes of duodenal fistula, however, there has been still lacking of ideal diagnosis and treatment by now. The primary treatment strategy of duodenal fistula is to determine the cause of disease and its key point is prevention, including perioperative parenteral and enteral nutrition support, improvement of hypoproteinemia actively, avoidance of stump ischemia by excessive separate duodenum intraoperatively, performance of appropriate duodenum stump suture to ensure the stump blood supply, and avoidance of postoperative input loop obstruction, postoperative stump bleeding or hematoma etc. Once duodenal fistula occurs, a simple and reasonable operation can be selected and performed after fluid prohibition, parenteral and enteral nutrition, acid suppression, enzyme inhibition, anti-infective treatment and maintaining water salt electrolyte and acid-base balance. Double tube method, duodenal decompression and peritoneal drainage can reduce duodenal fistula-related complications, and then reduce the mortality, which can save the lives of patients.

Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation. The key treatment of this complication is to promt diagnosis and effective hemostasis.(4) Blood supply disorder of Roux-Y intestinal loop: Main preventive principle of this complication is to pay attention to the blood supply of vascular arch in intestinal edge. (5) Anastomotic obstruction by big purse of jejunal stump: When Roux-en-Y anastomosis is performed after distal radical operation for gastric cancer, anvil is placed in the remnant stomach and anastomat from distal jejunal stump is placed to make gastrojejunal anastomosis, and the stump is closed with big purse embedding. The embedding jejunal stump may enter gastric cavity leading to internal hernia and anastomotic obstruction. We suggest that application of interruptable and interlocking suture and fixation of stump on the gastric wall can avoid the development of this complication.

Oesophageal rupture is a life-threatening complication of balloon tamponade for bleeding oesophageal varices. We herein describe the clinical course and imaging findings in a 33-year-old Indian man who had a Sengstaken-Blakemore (SB) tube inserted for uncontrolled haematemesis, which was unfortunately complicated by malposition of the gastric balloon with resultant oesophageal rupture. The inflated SB tube gastric balloon was visualised within the right hemithorax on chest radiography after the SB tube insertion. Further evaluation of the thorax on computed tomography confirmed the diagnosis of oesophageal rupture associated with right-sided haemopneumothorax. It is crucial for both the referring clinician and reporting radiologist to recognise early the imaging features of an incorrectly positioned SB tube gastric balloon, so as to ensure prompt intervention and a reduction in patient morbidity and mortality.

To evaluate the efficacy and safety of modified pedicle subtraction osteotomy for treatment of thoracolumbar old fracture with kyphosis.
 Methods: From January 2003 to January 2013, 58 patients of thoracolumbar kyphosis, who underwent modified pedicle subtraction osteotomy, were reviewed. Among them, 45 cases underwent initial operation and 13 cases underwent revision surgery. Preoperative and postoperative kyphotic Cobb's angle, score of back pain, as well as the incidence of complication were accessed by using visual analogue scale (VAS) and Oswestry disability index (ODI).
 Results: Mean follow-up duration was 42 months (range, 24-60 months). Average operative time was 258 min (range, 190-430 min), while average bleeding was 950 mL (range, 600-1 600 mL). All the patients were significantly improved in function and self-image, and achieved kyphosis correction with 17.9°± 4.3°. VAS of low back pain was decreased by 3.1±0.6; ODI was dropped by 25.3%±5.5%. 3 patients (5.2%) suffered anterior thigh numbness and got recovery after 3 months of follow-up. Complications happened in 19 patients, including 12 with cerebrospinal fluid leak, 4 with superficial wound infection, and 3 with urinary tract infection. All these complications were managed properly and none of them underwent reoperation.
 Conclusion: Modified pedicle subtraction osteotomy is a safe and effective technique for the treatment of old fracture with kyphosis.

OBJECTIVETo investigate the clinical outcomes of semicircular decompression in treating old thoracolumbar fractures and intractable neuropathic pain.

METHODSFrom September 2009 to September 2013, 21 patients with old thoracolumbar fracture and intractable neuropathic pain were treated with semicircular decompression. Among initial surgery, posterior pedicle screw fixation was used in these patients, with or without laminectomy. All patients were male, range in age from 20 to 28 years old with an average of (25.00±2.38) years. Vertebral body residual bone block resulted in intra-spinal placeholder more than 50%. All patients were complete spinal cord injury (ASIA grade) or cauda equina injury. VAS scores was from 6 to 10 points with the mean of 7.14±0.91. In these patients, MRI, CT, X-rays were performed; denomination and dosage of analgesics were recorded; nerve function and pain status were respectively evaluated by ASIA grade and VAS score before and after operation.

RESULTSAll patients were followed up from 8 to 32 months with an average of (17.29±6.02) months. All bone fragments of spinal canal were removed and spinal cord decompressions were achieved. At final follow-up, VAS scores were from 0 to 8 points with an average of (2.43±2.46) points, and were obviously reduced than peroperative data (P<0.05). Eleven cases of them stopped analgesic intake and 7 cases reduced using. Three patients' symptoms and VAS scores were not improved.

CONCLUSIONOld thoracolumbar fractures and intractable neuropathic pain need receive imaging examination as soon as possible and consider semicircular decompression therapy if bone fragments were in vertebral canal and spinal canal stenosis existed. This therapy can effectively relieve pain and profit nerve functional recovery.
