Patellar tendon rupture in children is especially rare. The fact that the area of traumatic rupture has wide variations makes surgical treatment difficult. We present an 11-year-old boy with acute traumatic patellar tendon rupture at the tibial tuberosity attachment without avulsion fracture. Primary end-to-end repair and reinforcement using 1.5 mm stainless steel wires as a surgical strategy were undertaken. Early range of motion began with a functional knee brace and the reinforced stainless wire was removed 3 months after surgery. Knee function at the final follow-up was satisfactory. We suggest that this strategy may provide a useful option for surgical treatment. PMID:28856026

Between 1983 and 1994, 15 patients (range 18 to 62 years) with acute traumatic Achilles tendon rupture, were treated surgically in our Department. We employed a modified Bosworth technique. The modifications were the use of a shorter strip of tendon and more secure fixation of the proximal and distal stump, than the original Bosworth technique. Postoperatively an above - knee plaster cast was applied with the knee flexed 30°-40° and the foot in a relaxed equinus position. The plaster cast was changed to a below - knee after 4 weeks and the foot gradually dorsiflexed to a neutral position until the 8th week, and then the plaster cast was removed. No patient had wound separation, infection or skin sloughs. After an average follow-up of 9 years, no rerupture has been reported and all the patients have returned to their pre injury activities.

Forty-three patients with aortic rupture secondardy to blunt trauma have been treated at the University of Micigan within the past 10 years with an overall salvage rate of 70%. The diagnosis should be suspected in anyone who has sustained a high speed decelerating injury, if the chest roentgenogram shows media-stinal widening, whether or not there is hypertension of the upper extremities; systolic murmur, or external evidence of chest injury. Aortography should be employed to confirm the diagnosis and to determine the site or sites of rupture. Repair of the lesion should be undertaken as soon as possible and takes priority in most instances over associated injuries. Repair in almost all cases can be accomplished safely and quickly using a bypass shunt without the aid of extracorporeal circulation. Images Fig. 1. Fig. 2. PMID:962399

Acute traumatic aortic injury is a potentially lethal condition with most patients die at the scene of the accidents. Rapid deceleration due to motor vehicle accidents is the commonest mechanism of injury. These injuries can be successfully repaired in the few patients who survive the initial trauma if proper diagnosis and rapid treatment are provided. The occurrence of acute traumatic aortic injury in patients with congenital abnormality of the aortic arch has been rarely reported; however, it renders the diagnosis and treatment more difficult. In this paper, we describe an extremely rare case of aortic injury in a young patient who had a right sided aortic arch with rupture of an aberrant left subclavian artery. The patient was suspected to have a Kommerell’s diverticulum in the aberrant subclavian artery origin. This injury resulted in an unusually huge pseudoaneurysm involving part of the mediastinum and extending into the neck. Unfortunately; patient succumbed in spite of surgical intervention.

We report the case of a patient who suffered major trauma following a motorcycle accident that resulted in multiple fractures, bilateral hemopneumothorax, pulmonary contusions, and an isthmic rupture of the aorta with a pseudoaneurysm compressing the descending aorta. This compression was responsible for distal hypotension and low flow, leading to acute renal insufficiency and massive rhabdomyolysis. Due to the critical clinical status of the patient, which prevented any type of open thoracic surgery, endovascular treatment was performed. An initial stent-graft permitted alleviation of the compression and the re-establishment of normal hemodynamic conditions, but its low position did not allow sufficient coverage of the rupture. A second stent-graft permitted total exclusion of the pseudoaneurysm while preserving the patency of the left subclavian artery.

An unusual case of traumatic pericardiophrenic rupture is presented. The defect was limited to the central tendon of the diaphragm, with herniation of the stomach into the pericardial sac. A correct preoperative diagnosis was not made because laparotomy was quickly performed for splenic rupture. Successful operative repair of the tear was performed, with interrupted reabsorbable sutures. The case is discussed and the management of patients with these rare lesions is reviewed.

If undiagnosed, traumatic pericardial rupture with herniation of the heart may have fatal consequences. We report two cases of multiple trauma with pericardial rupture, which was missed in the preoperative diagnoses of both patients, in spite of suggestive signs on computed tomographic scans. One patient had unexplained, persistent hemodynamic instability; the second patient had cardiac arrest during laparotomy for minor hepatic laceration. In both, the left-sided rupture of the pericardium with cardiac herniation into the pleural space was found and corrected in an emergency intervention. Both patients recovered completely. 2010 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

To describe 3 near-full-term, young-adult felids (2 domestic shorthair cats, and 1 bobcat [Lynx rufus]) that experienced uterine rupture following trauma. Two of the animals had motor vehicular trauma and 1 had abdominal bite wounds. The 2 domestic cats that were treated with surgical exploration and ovariohysterectomy recovered uneventfully. The bobcat died during hospitalization prior to surgical intervention, and necropsy identified uterine rupture and associated peritonitis. Traumatic uterine rupture should be considered in known or suspected pregnant animals that experience blunt or penetrating trauma, particularly if they are in late-term pregnancy. © Veterinary Emergency and Critical Care Society 2016.

Seven patients who had traumatic ruptures of the thoracic aorta are reported. Four of these died within a few hours of admission, allowing no opportunity for diagnosis or treatment. However, three survived long enough for elective surgery to be undertaken. A diagnosis of ruptured aorta was missed in one patient (case 2), and the difficulties of diagnosing this condition, even during thoracotomy, are emphasized. The value of serial chest radiography and forward aortography is discussed. Two of these patients underwent successful aortic repair, using left atrio-femoral bypass. Images PMID:5763507

Operative treatment of traumatic rotator cuff ruptures, i.e. ruptures with a predisposing traumatic event, is reported to yield superior results compared to operative treatment of non-traumatic, degenerative ruptures. The purpose of this study was to evaluate the difference of outcome, peroperative findings, and demographics after operative treatment of traumatic versus non-traumatic rotator cuff rupture. A total of 306 consecutive shoulders with an operated rotator cuff rupture (124 traumatic and 182 non-traumatic) were followed up. Constant and Murley score, size of the rupture, and age of the patients were used as an outcome measure. A total of 112 traumatic and 167 non-traumatic rotator cuff rupture shoulders were available for 1-year follow-up (91%). Mean Constant and Murley score was preoperatively lower in the traumatic group (46 versus 52, P = 0.01). At 3 months postoperatively, Constant and Murley scores were 61 and 60 (P = 0.72) and at 1 year 73 and 77 (P = 0.03), respectively. Altogether 91% of the patients in the traumatic and 93% in the non-traumatic group were satisfied with the final outcome (P = 0.45). In 94% of traumatic and 95% of a non-traumatic cases the rupture involved the supraspinatus tendon. In the traumatic group the rupture was larger and involved more frequently the whole supraspinatus insertion area (41% versus 17%, P < 0.0001). Mean age of patients was 58 and 57 years, respectively. Operative treatment of both traumatic and non-traumatic rotator cuff ruptures gives essentially good results. In our cohort, patients' recollection of predisposing trauma reflects the size of the rotator cuff rupture, but does not reflect the age of the patients.

Mortality from trauma remains a global public health challenge, with most preventable deaths due to bleeding. The recognition of acute traumatic coagulopathy as a distinct clinical entity characterized by early coagulation dysfunction, arising prior to medical intervention, has revolutionized trauma management over the last decade. The aim of this article is to review our current understanding of acute traumatic coagulopathy. We focus on recent advances in the mechanistic understanding of acute traumatic coagulopathy, particularly the changes in coagulation factors, physiological anticoagulants, endothelial activation, fibrinolysis and platelet dysfunction. Evolving diagnostic and therapeutic approaches are discussed, including viscoelastic coagulation monitoring and the role of tranexamic acid and blood products. Emphasis is now placed on early prevention, diagnosis, and aggressive initial treatment of coagulopathy and fibrinolysis with haemostatic blood products and tranexamic acid in addition to red cell units in order to reduce bleeding and improve clinical outcomes.

Although the Heimlich maneuver is considered the best intervention for relieving acute upper airway obstruction, several complications have been reported in the literature. These complications can occur as a result of an increase in abdominal pressure leading to a variety of well-documented visceral injuries, including the great vessels. Acute abdominal aortic thrombosis after the Heimlich maneuver is a rare but recognized event; however, to date no case of traumatic dissection and rupture of the abdominal aorta has been described. We report the first known case, to our knowledge, of a traumatic dissection and rupture of the abdominal aorta after a forcefully applied Heimlich maneuver.

This is a retrospective analysis of 50 postraumatic aortic rupture (1968-1996, 39 males, mean age: 34.5). Group A is composed of 35 patients with an acute aortic rupture and a prompt diagnosis. Group B includes 13 patients with a chronic rupture. All patients from group A had a severe politraumatism with abdominal, cranial, extremities or hip fractures. Mediastinal thickening with or without hemothorax indicated an angiography or a transesophageal echocardiography lately. In group A, 36 patients have been operated on urgently (12-24 hours); cardiopulmonary bypass was performed on 20 patients; an aorto-aortical bypass was done in 27 cases and a direct suture in the remaining 9. In group B, cardiopulmonary bypass was performed on 9 patients; a aorto-aortical bypass was done in 11 cases and a direct suture in 2. Overall hospital mortality was 16%; 19% in group A and 7.6% in group B. Ischemic paraplejia appeared in 5 patients (10%), all from group A. No false aneurysm developed after 4.5 years of follow-up (3-135 months) in the 38 survivors. The usefulness of transesophageal echocardiography, the importance of medular protection and the utility of several interventionist radiologic techniques are discussed.

To evaluate outcome differences in open surgical and endovascular treatment of traumatic aortic rupture (TAR) over a period of 30 years. We retrospectively reviewed the diagnostic workup and management of all patients and compared outcome before and since the era of endovascular therapy. Between 1980 and 2010, 72 patients with a mean age of 38 years (range, 14-76) were treated for TAR. Of these, 48 (67%) were treated by open surgery and the remaining 24 (33%) by thoracic endovascular aortic repair (TEVAR). In the open surgery group, mortality was 16.7% and paraplegia occurred in 8.3% of patients, whereas mortality was 4.2% and no paraplegia occurred in the TEVAR group. Diagnostic workup consisted of chest X-ray and arteriography in the early period, whereas computed tomographic scan and transesophageal echography were preferred in the more recent period. Although our results could not reach statistical significance, mainly because of the gross oversizing of the open group in comparison with the TEVAR group, TEVAR has introduced a less invasive era in the treatment of TAR and has become the therapy of choice. The diagnostic workup has evolved from chest X-ray and arteriography to computed tomographic scanning and even transesophageal echography. Copyright © 2011. Published by Elsevier Inc.

Patients with non-traumatic rupture of an aneurysm located at the anterior communicating artery (ACoA) often experience cognitive disabilities. It is unknown whether location of aneurysm also affects the possibility for improvement in functional independence compared to patients with an aneurysmal subarachnoid hemorrhage (a-SAH) located elsewhere. The aim was to explore the association between location of aneurysm (ACoA versus other) and level of functional independence, measured by Functional Independence Measure (FIM), at discharge from rehabilitation. Additionally, age and FIM at admission were explored. Historical cohort study among 107 patients with a-SAH based on data from a clinical database and a population-based register. Data were analyzed using multivariable logistic regression. Patients with ACoA were admitted with poorer cognitive FIM (median 6 (IQR 5-14) compared to patients with aneurysms located elsewhere (median 12 (IQR 6-23) (p = 0.0129); no difference at discharge. No association between aneurysm location and functional independence was observed. Higher age was associated with poorer outcome in bowel management OR 0.54 (95% CI 0.31-0.92), bladder management OR 0.59 (95% CI 0.35-0.98), comprehension OR 0.53 (95% CI 0.30-0.94), and memory OR 0.48 (95% CI 0.25-0.93). Overall, FIM at admission was associated with functional independence at discharge with the exception of stair walking and bladder management which did not reach statistical significance. ACoA was not associated with poorer level of functional independence compared to patients with a-SAH located elsewhere. Higher age was associated with poorer outcome in continence, comprehension, and memory, whereas higher FIM was associated with better functional independence across items at discharge.

Traumatic subarachnoid hemorrhage (TSAH) is a life-threatening intracranial bleed often associated with violent assault or motor vehicle accidents. The vast majority of TSAH is associated with rupture of the vertebral artery, although rare cases of traumatic aneurysm of the internal carotid artery (ICA) have been reported. A 27-year-old man was found bleeding and unresponsive following a violent altercation in which he received repeated blows to the head and neck. CT scan showed acute SAH, and death ensued within 24 h. Autopsy revealed generalized bruising of the face, a complete midline mandibular fracture, and massive basal SAH resulting from traumatic rupture of the right terminal internal carotid artery at the origin of the middle cerebral artery. Anterior and posterior neck dissection revealed focal hemorrhage associated with the right neural arch of the first cervical vertebra (C1). Autopsy findings were consistent with TSAH resulting from rupture of the ICA following blunt force trauma to the head. The rupture site in TSAH can be difficult to locate, and injury to the ICA may be overlooked if not routinely examined. Dissection of the neck and skull base is required to ensure accurate identification of the site of vascular injury. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Three large tympanic membrane (TM) perforations (occupying more than one quadrant) were treated with hyaluronan (1% hyaluronic acid) without delay after the accident. Using the highly viscous hyaluronan as an aid, the margins of the perforations could be noticeably restored. The size of the perforation could be immediately reduced to roughly half of its original size. Immediate restoration and covering of a traumatically ruptured TM wound improve the healing potential of the drum and counteract middle ear infection.

The authors present 7 patients who suffered iliac artery rupture over a 2 year period. In 5 patients, the rupture was iatrogenic: 4 cases were secondary to balloon angioplasty for iliac artery stenosis and 1 occurred during coronary angioplasty. In the last 2 patients, the rupture was secondary to iliac artery mycotic aneurysm. Direct placement of a stent-graft was performed in all cases, which was dilated until extravasation was controlled. Placement of the stent-graft was successful in all the cases, without any complications. The techniques used, results, and mid-term follow-up are presented. In conclusion, endovascular placement of a stent-graft is a quick, minimally invasive, efficient, and safe method for emergency treatment of acute iliac artery rupture, with satisfactory short- and mid-term results.

This report describes a 66-year-old man who presented with progressive paraparesis after a fall. Magnetic resonance imaging showed an acute spinal hematoma at T11-12 with spinal cord compression. The patient underwent an emergency left T11-12 hemilaminectomy. The hematoma was subarachnoid and the source of bleeding was an injured radicular vein. To the best of our knowledge, this is the first reported case of traumatic spinal subarachnoid hematoma. We discuss the possible mechanism and our case illustrates an injured radicular vein can be a source of traumatic spinal subarachnoid hematoma.

A myocardial bridge (MB) is a common anatomic variant, most frequently located in the left anterior descending coronary artery, where a portion of the coronary artery is covered by myocardium. Importantly, MBs are known to result in a proximal atherosclerotic lesion. It has recently been postulated that these lesions predispose patients to acute coronary events, even in cases of otherwise low-risk patients. One such mechanism may involve acute plaque rupture. In this article, we report 2 cases of patients with MBs who presented with acute coronary syndromes despite having low cardiovascular risk. Their presentation was life-risking and both were treated urgently and studied with coronary angiographies and intravascular ultrasound. This latter modality confirmed a rupture of an atherosclerotic plaque proximal to the MB as a likely cause of the acute events. These cases, of unexplained acute coronary syndrome in low-risk patients, raise the question of alternative processes leading to the event and the role MB play as an underlying cause of ruptured plaques. In some cases, an active investigation for this entity may be warranted, due to the prognostic implications of the different therapeutic modalities, should an MB be discovered. PMID:28251167

Traumatic rupture of the descending thoracic aorta remains a leading cause of death following major blunt trauma. Management has evolved from uniformly performing emergent open repair with clamp and sew technique to include open repair with mechanical circulatory support, medical management and most recently, endovascular repair. This latter approach appears, in the short term, to be associated with perhaps better outcome, but long term data is still accruing. While an attractive option, there are specific anatomic and physiologic factors to be considered in each individual case. PMID:20676277

To compare the therapeutic results of deferred urgent surgical treatment and late treatment of traumatic ruptures of the posterior urethra. 35 patients with a mean age of 25 years (range: 7 to 79 years) were operated for trauma of the posterior urethra. In most cases, trauma was secondary to a road accident, associated with fracture of the pelvis. When rupture of the posterior urethra was diagnosed, the subsequent management depended on the patient's general condition and associated lesions. In the absence of serious skeletal or visceral lesions, the patient was operated within 3 weeks following trauma, after radiological assessment. This approach was applied in 16 patients (Group I). The other 19 patients (Group II) were only operated at the sixth month, after stabilization of all traumatic lesions. Results were assessed in terms of the quality of the urinary stream, urinary continence and sexual impotence. The stream was considered to be good in 93.75% of cases (Group I) and 78.8% of cases (Group II). Continence was perfect in 100% of cases (Group I), versus 89.4% (Group II) and sexual impotence was observed in 18.7% (Group I) versus 5.3% (Group II). Trauma of the posterior urethra, without any serious associated lesions, can be operated as a deferred emergency with excellent results in terms of voiding (80% of good results), but with a higher frequency of sexual impotence. In patients with serious associated lesions, the therapeutic management of the urethral trauma is performed after an interval of 3 to 6 months, at the stage of urethral stricture. In this case, surgery consists of resection of the fibrous callus, followed by urethral anastomosis. The results of this operation are good, at the cost of repeated stricture, treated endoscopically, but with a lower incidence of sexual impotence.

Cardiac rupture is a catastrophic complication of acute myocardial infarction with highly mortality rate. Three types of rupture are ventricular free wall rupture( VFR), ventricular septal rupture( VSR), and papillary muscle rupture( PMR). A combination of any 2 types of rupture is called ventricular double rupture (VDR), and very rare. We report a case of VDR (VSR and VFR) after acute myocardial infarction. A 76-year-old female with heart failure was admitted to our hospital. Echocardiography showed an apical VSR and pericardial effusion. She was diagnosed with VDR and emergent operation was performed. During operation, the site of VFR was right ventricle, which was the same infarction area of VSR. VSR was closed by infarction exclusion technique, concurrently excluding the site of VFR. VFR was successfully repaired by mattress sutures. Post-operative course was good without heart failure, though residual shunt was remained. The patient survived and was discharged from our hospital.

Ventricular septal rupture (VSR) is a complication of acute myocardial infarction (AMI) that is associated with significant mortality. We aim to review the clinical outcome in the current era. Patients admitted to a single tertiary centre from 1997 to 2008 with VSR post-AMI were identified from the local cardiac registry. We performed a retrospective review on 25 patients. Mean age (15 women) was 71 years. Most patients had cardiovascular risk factors (84%); the commonest was hypertension (72%). Anterior AMI (80%) and apical VSR (84%) formed the majority of the cases. Eleven patients (44%) received prior coronary reperfusion therapy either via thrombolysis or PCI. Median time to rupture was 1 day from diagnosis of infarction. More than half (60%) of the patients were in Killip class 3 or 4 at diagnosis of rupture. Mean left ventricular ejection fraction (LVEF) was 33 +/- 10%. Most patients (80%) required IABP for haemodynamic support. All patients who underwent surgery had ventricular septal repair; amongst them 47% had concomitant CABG. Those managed conservatively were older (P = 0.01). Overall mortality rate was 44%. Most died within the first four days (82%). Surgical and non-surgical survival rates were 68% and 17%, respectively (P= 0.039). Patient demographics, prior coronary reperfusion techniques, Killip class status and LVEF were not significant predictors of mortality. However, non-anterior wall AMI and non-apical VSR were significantly associated with poorer survival (P = 0.009, P = 0.026 respectively). While the occurrence ofVSR post-AMI appears to be low compared to earlier studies, it continues to be associated with significant mortality. Non-anterior wall AMI and non-apical VSR were associated with poorer survival and surgical repair conferred survival advantage over conservative management.

To review the progress in the treatment of acute Achilles tendon rupture. Recent literature about the treatment of acute Achilles tendon rupture was reviewed and analyzed. Treatments of acute Achilles tendon rupture include operative and non-operative treatments. Operative treatments include open surgery and percutaneous minimally invasive surgery. Compared with non-operative treatment, operative treatment can effectively reduce the re-rupture incidence, but it had higher complication incidences of wound infection and nerve injury. Although early functional rehabilitation during non-operative treatment could reduce the re-rutpture incidence, there is no consistent orthopaedic device and guideline for functional rehabilitation. Both operative and non-operative treatments have advantages and disadvantages for the treatment of acute Achilles tendon rupture. No consistent conclusion is arrived regarding functional recovery. Future studies should explore the strategy of early functional rehabilitation during non-operative treatment and its mechanism of promoting tendon healing.

To report a rare case of traumatic wound dehiscence caused by the use of a continuous positive airway pressure (CPAP) mask in a patient with chronic obstructive pulmonary disease (COPD) after penetrating keratoplasty (PKP). Observational case report. A 55-year-old man who was treated with uncomplicated PKP due to pellucid marginal corneal degeneration in the right eye 9 months earlier presented to the emergency department after a globe rupture caused by dislocation of his CPAP mask during sleep. The best-corrected visual acuity (BCVA) was light perception in the right eye. The corneal graft was dehisced from 12 over 3 to 6 o'clock (180 degrees) with interruption of the double running corneal sutures and nasal iris as well as vitreous incarceration. The graft was resutured in place with 33 interrupted 10-0 monofilament nylon sutures. The BCVA improved to 20/100 three months after globe reconstruction. This case underlines the necessity of education for patients undergoing keratoplasty regarding the use of protective eyewear, to avoid predictable or accidental ocular injuries and graft dehiscence or its subsequent consequences. CPAP masks should be fitted (eyeball sparing) to the margins of the orbit after PKP.

Background Blunt traumatic cardiac rupture is rare. However, such cardiac ruptures carry a high mortality rate. This study reviews our experience treating blunt traumatic cardiac rupture. Methods This retrospective study included 21 patients who experienced blunt traumatic cardiac rupture from 1999 to 2015. Every patient underwent surgery. Several variables were compared between survivors and fatalities. Results Sixteen of the 21 patients survived, and 5 (24%) died. No instances of intraoperative mortality occurred. The most common cause of injury was a traffic accident (81%). The right atrium was the most common location of injury (43%). Ten of the 21 patients were suspected to have cardiac tamponade. Significant differences were found in preoperative creatine kinase–myocardial band (CK-MB) levels (p=0.042) and platelet counts (p= 0.004) between the survivors and fatalities. The patients who died had higher preoperative Glasgow Coma Scale scores (p=0.007), worse Trauma and Injury Severity Scores (p=0.007), and higher Injury Severity Scores (p=0.004) than those who survived. Conclusion We found that elevated CK-MB levels, a low platelet count, and multi-organ traumatic injury were prognostic factors predicting poor outcomes of blunt cardiac rupture. If a patient with blunt traumatic cardiac rupture has these factors, clinicians should be especially attentive and respond promptly in order to save the patient’s life. PMID:27965920

Aims The main aim of this article is an analysis of both advantages and disadvantages of the modern solutions of treatment – percutaneous surgery, in comparison with the classic methods of treatments described in the surgery of Achilles’ tendon. Patients and method The study was conducted on 23 patients admitted to the Orthopedics and Traumatology Clinic of Cluj-Napoca between January 2011–June 2012. Nineteen (19) patients were diagnosed with a complete rupture of the Achilles tendon and 4 patients with a partial rupture. The diagnosis of traumatic Achilles tendon ruptures was usually clinical, the Ultrasound (common or 3D) and the MRI confirmed the lesion and determined its location and extension. We analyzed the diagnostic methods, the elapsed time before surgery, the treatment options depending on lesion’s location, technical difficulties, costs, postoperative care, the average healing time, complications. Results The Ultrasound was performed in 65.2% of the patients (15 patients) for confirming the extension of the lesion and it served for pre-operative planning. In most of the cases, the classical methods of Achilles tendon reconstruction were used (18 cases). The complications rate was about 8%. We diagnosed an iterative Achilles tendon rupture (the patient was initially treated using the percutaneous methods) and a delay in cicatrisation. Conclusions The percutaneous surgical techniques are a viable alternative for the acute ruptures of Achilles tendon, the classic intervention has clear indications in lesions diagnosed late, in the recurrent tendon ruptures.

Triceps tendon ruptures are uncommon injuries primarily occurring in young, active males or elderly individuals with various systemic diseases. Relatively little is known about the epidemiology of this injury, or the results of surgical management in high-demand populations. The purpose of this study was to define the incidence and outcomes of surgical treatment in active duty American military personnel. The Military Data Repository (MDR) was queried for all active duty military personnel undergoing surgical repair or reconstruction of a triceps tendon rupture between January 2012 and December 2014. The electronic health records of all patients with at least 12 months clinical follow-up were searched for demographic information, injury details, preoperative imaging findings, post-operative complications, and ability to return to duty following surgical repair. Incidence was calculated based on total active duty population in the MDR over the study period. Risk factors for postoperative complication and inability to return to duty following surgical repair were assessed using univariate analyses. A total of 54 acute triceps tendon ruptures were identified in the search, of which 48 had at least 12 months follow-up and complete post-operative records. The incidence of acute triceps tendon rupture was 1.1 per 100,000 person-years. Twelve patients experienced post-operative complications, six of which were traumatic re-ruptures within four months of the index surgery. No patient had a post-operative infection or atraumatic repair failure. 94% of patients were able to return to active military service following surgical repair. Enlisted rank was a significant risk factor for a post-operative complication, but no factor predicted inability to return to active duty service. Surgical repair of acute triceps tendon ruptures reliably restores strength and function even in high-demand individuals. In our population, traumatic rerupture was the most common complication

Pectoralis major (PM) ruptures are uncommon injuries, although they are becoming more frequent. We report a case of a PM rupture in a young male who presented with axillar pain and absence of the anterior axillary fold after he perceived a snap while lifting 200 kg in the bench press. Diagnosis of PM rupture was suspected clinically and confirmed with imaging studies. The patient was treated surgically, reinserting the tendon to the humerus with suture anchors. One-year follow-up showed excellent results. The patient was recording his training on video, so we can observe in detail the most common mechanism of injury of PM rupture. PMID:27595030

Traumatic aortic rupture is rupture of all or part of the aortic wall, mostly resulting from blunt trauma to the chest. The most common site of rupture is the aortic isthmus. Traumatic rupture of the ascending aorta is rare. A 62-year-old man with a family history of ascending aortic aneurysm was referred to our hospital after a motor vehicle accident. He had symptoms of cardiogenic shock. A contrast-enhanced computed tomographic scan revealed rupture of the proximal ascending aorta and an ascending aortic aneurysm with a diameter of 55 mm at the level of the sinuses of Valsalva. Transthoracic echocardiography at the bedside revealed severe aortic valvular insufficiency. We performed a successful Bentall procedure. During postoperative recovery, the patient experienced a cerebrovascular accident. Transesophageal echocardiography did not reveal thrombosis of the mechanical prosthesis. The patient's symptoms resolved in time, and he was discharged from the hospital on postoperative day 47 without any sequelae. He has been symptom free during a 6-month follow-up period. We suggest that individuals who have experienced blunt trauma to the chest and have symptoms of traumatic aortic rupture and a known medical history of ascending aortic aneurysm should be evaluated for a rupture at the ascending aorta and the aortic isthmus.

Diaphragmatic rupture following blunt abdominal trauma is an uncommon life-threatening injury in children. In addition to its high mortality rate, there is a significant amount of morbidity associated with this injury. Emergency medicine physicians must maintain a high index of suspicion for diaphragmatic rupture and its associated complications when evaluating victims of blunt abdominal trauma.

Rupture of the common extensor tendon is the most common acute tendon injury of the elbow. The authors describe a case of a patient with a clinical history of tendinopathy caused by functional overload of the common extensor tendon, treated also with infiltrations of steroids, and subsequent partial rupture of the tendon during sport activity. The diagnosis was made clinically and at ultrasound (US) examination; US follow-up after some time showed the healing of the lesion. This case confirms that injections of steroids may be a contributory cause of tendon rupture, and emphasizes the sensitivity and specificity of US in the study of pathologies of the elbow tendons.

The present article was designed to report the results of the analysis of the cases of traumatic and spontaneous ruptures of the organs affected by the tumours based on the original observations and the literature data. It is shown that the probability of the tumour rupture depends on its histological type, localization, the size, and the distance from the capsule of the affected organ, the degree of involvement of the major blood vessels, the severity of the necrotic changes, the presence of cysts in the neoplasm, and the regimens of radio- and chemotherapy. Moreover, the rupture can be facilitated by anticoagulation therapy, intake or oral contraceptives, pregnancy, concomitant diseases, alcoholic intoxication, splenomegaly, and hypocoagulation resulting from dissemination of the neoplastic process or the metastatic lesions of the liver. Even a minimal injury to the skin can provoke the tumour rupture associated with the fatal hemorrhage. A delayed rupture within a few hours or days is possible.

Delayed traumatic intracerebral hematoma (DTICH) is a rare complication of head injury that appears suddenly after an interval of several days or months. Here, we report a case of DTICH during antiplatelet therapy for vasospasm following surgeries for a ruptured left internal carotid-posterior communicating (ICPC) aneurysm and right acute epidural hematoma (EDH). A 77-year-old man with no medical history was diagnosed with a subarachnoid hemorrhage (SAH) due to rupturing of a left ICPC aneurysm and a right linear fracture of the right parietal bone due to a head injury following the rupture. On day 2, the patient underwent successful clipping of the left ICPC aneurysm. Computed tomography (CT) performed post-clipping revealed a right acute EDH below the linear fracture of the right parietal bone, which was removed immediately. A next-day CT revealed minor contusions in both temporal poles. Fasudil, ozagrel, and cilostazol were administered from Day 3 post-clipping and EDH evacuation to prevent vasospasm. The contusions did not enlarge until Day 10. On Day 11, the patient became comatose, and a huge hematoma was identified in the right temporal lobe to frontal lobe. Although the hematoma was removed immediately, the patient died on Day 13. The hematoma was considered to be a rare case of DTICH that developed from a minor contusion of the right temporal lobe during antiplatelet therapy for vasospasm. In cases of aneurysmal SAH with head injury and contusion, we must pay attention to DTICH and select more deliberate treatment for vasospasm.

A laboratory study was performed to evaluate the histopathological features of the macroscopically intact portion of the Achilles tendon in patients undergoing surgery for an acute rupture of the Achilles tendon. Tendon samples were harvested from 29 individuals (21 men, 8 women; mean age: 46 ± 12) who underwent repair of an Achilles tendon tear tear, and from 11 male patients who died of cardiovascular events (mean age: 61). Three pieces of tendon were harvested: at the rupture site, 4 cm proximal to the site of rupture, 1 cm proximal to the insertion of the Achilles tendon on the calcaneum. Slides were assessed using a semiquantitative grading scale assessing fiber structure and arrangement, rounding of the nuclei, regional variations in cellularity, increased vascularity, decreased collagen stainability, and hyalinization. Intra-observer reliability of the subscore readings was calculated. The pathological features were significantly more pronounced in the samples taken from the site of rupture than in the samples taken proximally and distal to it (0.008 < P < 0.01). There were no significant differences in the mean pathologic sum-scores in the samples taken proximally and distal to the site of rupture. Unruptured Achilles tendons, even at an advanced age, and ruptured Achilles tendons are clearly part of two distinct populations, with the latter demonstrating histopathological evidence of failed healing response even in areas macroscopically normal.

Fatal complications following the performance of the Heimlich maneuver have been reported. A 76-year-old woman presented to the emergency department with signs of respiratory distress, abdominal pain and distension one day after airway obstruction and subsequent resuscitation. Despite successful immediate laparotomy and repair of a ruptured stomach, she later succumbed to the sequelae of aspiration of gastric contents and dehiscence of the gastric tear. This is the 4th case of stomach rupture and the 7th reported fatal complication following the Heimlich maneuver. It is recommended that persons who undergo the Heimlich maneuver be examined and observed by a physician, as soon as possible, to rule out complications.

A 29-year-old man, a known epileptic, presented to an accident and emergency department following a tonic-clonic seizure, suffering a second seizure in the department. Subsequently, he reported neck pain, swelling and stiffness. An otorhinolaryngology neck examination revealed a tender left side with two palpable masses and a reduced range of movement. Ultrasound confirmed a ruptured middle third of the left sternocleidomastoid muscle, which was successfully treated non-surgically with analgaesia and intensive physiotherapy. Uncommonly, sternocleidomastoid muscle rupture has been reported following high-velocity trauma, but to the best of our knowledge this is the first case described in the literature following an epileptic seizure.

The purpose of this study was to examine patient characteristics and outcomes in a group of consecutive patients with ruptured globe eye injuries at Kings County Hospital Center, a large, urban, level 1 trauma center. A retrospective chart review was performed to identify all patients with ruptured globe eye injuries seen between January 2009 and October 2011. Thirty-eight patients who sustained ruptured globe eye injuries from all causes were investigated for etiology and final visual outcomes. Eight eyes in which vision could be assessed were evaluated as having no light perception at presentation and three of these eyes required primary enucleation. Of the 38 eyes, orbit fractures were found in 15 eyes and an intraocular foreign body was found in six eyes. Our cohort revealed a 37.5% rate of primary enucleation in eyes with no light perception, which we believe to be a reflection of the severity of injury. All three cases were secondary to a gunshot wound. Further, our sample, although small in size, revealed a very high percentage of eyes that were ruptured secondary to violent causes compared with other studies.

Specify the clinical and progressive characteristics of acute rupture of hydatid cysts in the peritoneum. We retrospectively studied patients who had undergone surgery for a hydatid cyst (HC) of the abdomen between January 1990 and December 2000 and in whom the exploration had confirmed the diagnosis of acute rupture of a hydatid cyst in the peritoneum. Over this period of 11 Years, 970 patients had undergone surgery for hydatid cysts of the liver and the spleen, 17 of whom had presented an acute rupture of the hydatid cyst in the peritoneum, that is to say 1.75% of the cases. The mean age was 30 Years and sex ratio was 0.41. Rupture was secondary to a trauma in 6 cases and to an intense physical effort in one case. The clinical table was acute peritonitis in 14 cases, acute intestinal occlusion in one case, suggested anaphylactic shock in one case, and a non-complicated hydatid cyst in one case. Ultra-sonographic diagnosis was made in all the cases, but that of rupture in 12 cases only. No scans were performed. Intervention was decided on within a delay of less than 72 hours in 16 cases. Surgical treatment consisted in the treatment of the peritonitis, the ruptured hydatid cyst, the associated hydatid cysts in the liver and the spleen, and the hydatid cyst of the right lung in two cases. Post-operative follow-up was complicated in 4 cases with two deaths through septic shock. Distant follow-up was marked by a secondary peritoneal hydatidosis in a patient whom has not benefited from medical treatment. The latter, based on albendazole, was prescribed in 6 patients with satisfying results and a mean follow-up of 32 months. The therapeutic progress has improved the prognosis of ruptured hydatid cysts in the peritoneum. Secondary peritoneal hydatidosis is fundamentally enhanced by the delay in diagnosis and treatment and the absence of medical treatment. The optimal strategy is to treat the patients at the non-complicated stage of the hydatid cyst and, above all

Background: Dermoid tumors are benign congenital cystic lesions that usually present with local mass effect. Very rarely, they present as spontaneous ruptures. Traumatic rupture of these dermoid cysts is an extremely rare event and only a handful of such cases have been ever reported. Case Description: A 47-year-old female presented to our hospital with a ruptured intracranial dermoid cyst following a mild head injury. The ruptured cyst contents were disseminated into the subarachnoid and intraventricular compartments, resulting in an obstructive hydrocephalus. After medical stabilization, she underwent gross total resection of the cyst using combined transsylvian, transcortical-transventricular, and sub-frontal approaches. A ventriculo-peritoneal shunt was eventually also needed. Conclusion: Traumatic rupture of an intracranial dermoid cyst is an extremely rare event and this is only the fourth such case reported in the literature. We presume that this rupture occurs due to sudden shifts in the cyst sac, which is adherent to some partially mobile intracranial contents. Although computed tomography (CT) is often adequate in making a diagnosis of this entity, magnetic resonance imaging (MRI) provides complete characterization of the extent of lipid dissemination, and is essential for operative planning. Intravenous steroids at presentation are helpful in managing the aseptic meningitis associated with rupture. Complete surgical resection is the goal, but must be weighed against the risk for injury to nearby vital structures. Hydrocephalus should be managed promptly, and patients should be monitored for it closely in the perioperative period. Even though the recurrence rate with subtotal resection is extremely rare, follow up should be done routinely. PMID:23869280

The case of a 93-year-old man who received a Heimlich maneuver while choking is reported. After the procedure, the patient presented with abdominal pain and ultimately was found to have developed a gastric rupture. He was hospitalized for 66 days. Review of the literature showed that only four gastric perforations related to the Heimlich maneuver have been documented. Other complications have occurred. It is reasonable to perform the procedure as an alternative to asphyxiation, but emergency physicians must be aware of the fact that life-threatening complications may ensue.

Patellar duplication is a rare asymptomatic condition. The diagnosis is often made following a traumatic event associated with an injury to the knee extensor mechanism. The treatment is often surgical and consists in removal of the smaller part of the patella with tendon reinsertion. The presence and rupture of an intermediate tendon between the two parts of the patella have not been reported in the modern literature. We present a traumatic rupture of an intermediate tendon in a patient with horizontal patellar duplication. The surgical management consisted of tenorrhaphy protected with a figure-of-eight tension band wire approximating the two parts of the patella. The patient recovered full knee range of motion and quadriceps strength at the last 8-month follow-up. PMID:28255488

Achilles injury is a common musculoskeletal disorder. Bilateral rupture of the Achilles tendon, however, is much less common and usually occurs spontaneously. Complete, traumatic, and bilateral ruptures are rare and typically require long periods of immobilization before the patient can return to full weightbearing. A 52-year-old male was hospitalized for bilateral traumatic rupture to both Achilles tendons. No risk factors for tendon rupture were found. Blood samples revealed no peripheral blood pathologic features. Both tendons were repaired with percutaneous, minimally invasive surgery using the Achillon(®) tendon suture system. Rehabilitation was begun 4 weeks later. An ankle-foot orthosis was prescribed to provide ankle support with an adjustable range of movement, and active plantar flexion was set at 0° to 30°. The patient remained non-weightbearing with the ankle-foot orthosis device and performed active range-of-motion exercises. At 8 weeks after surgery, we recommended that he begin walking with partial weightbearing using a foot-tibial orthosis with the range of motion set to 45° plantar flexion and 15° dorsiflexion. At 10 weeks postoperatively, he was encouraged to return to full weightbearing on both feet. Beginning rehabilitation as soon as possible after minimally invasive surgery, compared with 6 weeks of immobilization after surgery, provided a rapid resumption to full weightbearing. We emphasize the clinical importance of a safe, simple treatment program that can be followed for a patient with damage to the Achilles tendons. To our knowledge, ours is the first report of minimally invasive repair of bilateral simultaneous traumatic rupture of the Achilles tendon.

Pain in the posterosuperior portion of the calcaneus can be caused by a retrocalcaneal bursitis, enlargement of the superior bursal prominence of the calcaneus, insertional Achilles tendinopathy, stress fracture of the calcaneus, or inflammation of an adventitious bursa between the Achilles tendon and the skin. Hypertrophied tendon impinging on the posterosuperior calcaneal tuberosity can be a cause of retrocalcaneal pain after repair of acute rupture of the Achilles tendon. This can be effectively treated by endoscopic calcaneoplasty. Therapeutic, Level IV, Case Report.

Atraumatic splenic rupture is an uncommon complication of acute pancreatitis. This report describes the case of a 30-year-old man with acute pancreatitis and splenic vein thrombosis complicated by splenic rupture. The patient was admitted to the emergency department with pain in the upper abdomen that had been present for six hours and was associated with vomiting and sweating. He was diagnosed with acute pancreatitis of alcoholic etiology. Upon computed tomography (CT) of the abdomen, the pancreatitis was scored as Balthazar C grade, and a suspicious area of necrosis affecting 30% of the pancreas with splenic vein thrombosis was revealed. Seventy-two hours after admission, the patient had significant improvement in symptoms. However, he showed clinical worsening on the sixth day of hospitalization, with increasing abdominal distension and reduced hemoglobin levels. A CT angiography showed a large amount of free fluid in the abdominal cavity, along with a large splenic hematoma and contrast extravasation along the spleen artery. The patient subsequently underwent laparotomy, which showed hemoperitoneum due to rupture of the splenic parenchyma. A splenectomy was then performed, followed by ultrasound-guided percutaneous drainage. PMID:26425272

This report describes two cases of traumatic closed index extensor tendon rupture at the musclotendinous junction. Both patients were injured when their work gloves were caught in the revolving parts of machines, and both were treated surgically. One of the patients completely ruptured the index extensor digitorum communis (EDC) and the extensor indicis proprius (EIP) tendons at the musclotendinous junction of dorsal forearm. In this patient, the distal stump of the index EDC tendon was sutured to the middle EDC tendon in an end-to-side juncture. The other patient completely ruptured the EIP tendon and partially ruptured the index EDC tendon at the musclotendinous junction. In this patient, tendon transfer of the extensor digiti minimi (EDM) to the EIP tendon and plication of the index EDC tendon were performed. In both cases, surgical intervention enabled the patients to extend their index fingers almost normally; however, the former complained of inability to extend his index finger independently. Tendon transfer of the EDM in cases of index extensor tendon rupture at the musclotendinous junction is a good method to restore ability to independently extend the index finger. However, consideration should be given to anatomical variation in the little finger. The EDC tendon is sometimes absent leaving the EDM tendon as the only extensor tendon to the little finger.

Acute traumatic spinal cord injury (SCI) is a devastating disease process affecting tens of thousands of people across the USA each year. Despite the increase in primary prevention measures, such as educational programs, motor vehicle speed limits, automobile running lights, and safety technology that includes automobile passive restraint systems and airbags, SCIs continue to carry substantial permanent morbidity and mortality. Medical measures implemented following the initial injury are designed to limit secondary insult to the spinal cord and to stabilize the spinal column in an attempt to decrease devastating sequelae. This chapter is an overview of the contemporary management of an acute traumatic SCI patient from the time of injury through the stay in the intensive care unit. We discuss initial triage, immobilization, and transportation of the patient by emergency medical services personnel to a definitive treatment facility. Upon arrival at the emergency department, we review initial trauma protocols and the evidence-based recommendations for radiographic evaluation of the patient's vertebral column. Finally, we outline closed cervical spine reduction and various aggressive medical therapies aimed at improving neurologic outcome.

Controversy exists regarding the optimal treatment for acute Achilles tendon ruptures. Conservative and surgical treatments have been reported with variable results and complications rates. The purpose of this study is to compare the postoperative clinical and functional results of percutaneous versus open repair of acute Achilles tendon ruptures. We present 34 patients with acute Achilles tendon ruptures treated with open and percutaneous surgical repair. There were 15 patients who had open surgical repair and 19 patients who had percutaneous repair. The mean follow-up was 22 months (range 10-24 months) for the open repair group and 20 months (range 9-24 months) for the percutaneous repair group; no patient was lost to follow-up. Postoperative rehabilitation was the same for both groups. Wound healing, complications, ankle range of motion, and patients' return to work, activity level, weight-bearing, and subjective assessment of their treatment were recorded. No significant difference was observed with respect to any of the examined variables between the open and percutaneous repair groups. Tendon healing was observed in all patients of both groups by 7-9 weeks. The mean time of patients' return to work was 7 weeks for the open repair group and 9 weeks for the percutaneous repair group. All patients were capable of full weight bearing by the 8th postoperative week time; the time to return to previous activities including non-contact sports was 5 months for both groups. All patients expressed satisfaction and graded their treatment as good. As expected, cosmetic appearance was significantly better in the percutaneous repair group. One patient who had open repair experienced skin incision pain and dysesthesia and graded his operation as fair. No patient experienced other complications such as re-rupture, infection, sural neuroma, or Achilles tendinitis within the period of this study. The present study showed similarly successful clinical and functional results

To determine the incidence of acute traumatic coagulopathy in dogs suffering severe trauma and to investigate the association of markers of hypoperfusion with coagulation abnormalities. A prospective observational study performed June, 2009 to February, 2011. A university teaching hospital. Thirty client-owned dogs weighing >5 kilograms that were presented to the Tuft's Cummings School of Veterinary Medicine following severe trauma as defined by an animal trauma triage score (ATT) ≥5 and having received no resuscitation with IV fluids or blood products prior to blood sampling. None. Prior to resuscitation, data obtained at the time of admission to the emergency service included HCT, platelet count, lactate concentration, pH, base excess, thromboelastrogram (TEG), prothrombin time, activated partial thromboplastin time, fibrinogen level, and protein C activity. Rectal temperature and ATT were recorded for all dogs. Neither HCT nor platelet count was significantly decreased in any of the dogs. Based on G values as measured by TEG, 10/30 dogs (33%) showed evidence of hypercoagulability. Hypocoagulability as determined by prothrombin time, activated partial thromboplastin time, or TEG was not shown in any of the 30 dogs. Dogs with severe trauma may experience hypercoagulability that is unrelated to fluid resuscitation or transfusion therapy. Future studies are warranted to better characterize coagulation changes in dogs with severe trauma, particularly in relationship to fluid therapies and/or hemorrhage. © Veterinary Emergency and Critical Care Society 2013.

Acute compartment syndrome after muscle rupture, although rare, is a limb threatening condition, which warrants emergency treatment. The case of acute compartment syndrome secondary to a gastrocnemius muscle tear of the right lower leg, in a non-athlete is reported. To our knowledge, this is the only description of acute compartment syndrome due to muscle rupture in a non-athlete. PMID:10505928

Multidetector CT (MDCT) is an imaging technique that provides otherwise unobtainable information in the diagnostic work-up of patients presenting with acute abdominal pain. A correct working diagnosis depends essentially on understanding the individual patient's clinical data and laboratory findings. In haemodynamically stable patients with acute severe and generalized abdominal pain, MDCT is now the preferred imaging test and gives invaluable diagnostic information, also in unstable patients after stabilization. In this descriptive review, we focus our attention on acute, severe and generalized or undifferentiated non-traumatic abdominal pain. The main differential diagnoses are acute pancreatitis, gastrointestinal perforation, ruptured abdominal aneurysm and acute mesenteric ischaemia. We will provide radiologist readers with a technical guide to optimize MDCT imaging protocols and list the major CT signs essential to reach a correct diagnosis and guide the best treatment.

Spontaneous splenic artery aneurysm (SAA) is a rare but a life-threatening condition. Thus, early diagnoses may increase the chance of survival. A 52-year-old female patient was admitted to the emergency department with a pain that starts from the chest and epigastric region and radiates to back and left arm. The patient prediagnosed as having acute myocardial infarct and was under observation when acute abdomen and hemorrhagic shock developed. After further investigation, the patient was diagnosed as having SAA and has undergone a successful surgery. The patient was fully cured and discharged from the hospital on the seventh postoperative day. The patient originally presented with SAA, although she was primarily observed in the emergency department with acute myocardial infarct diagnosis because of similar symptoms and clinical findings to cardiovascular diseases. When changes in the clinical picture occurred, the patient was reevaluated and had undergone an operation because of SAA rupture. Therefore, physicians should take into consideration of aneurysm rupture in the differential diagnosis of the cardiovascular conditions; otherwise, the patient may lose his/her life.

A 27-year-old man was injured during a motocross game. He was suffered from dyspnea, orthopnea, and hemoptysis. The to-and-fro murmur was noticed 3 days after the accident and then the patient was admitted to our hospital. Echocardiography revealed severe aortic regurgitation. Computerized tomography also showed severe pulmonary contusions. Seventeen days after the accident the aortic valve replacement was performed. The aortic valve was anterior-posterior type bicuspid valve (fusion of right coronary cusp and light coronary cusp) and the tear was detected in the anterior cusp. The postoperative course was uneventful. Rupture of the aortic valve due to a blunt chest trauma is rare and reported in 20 cases previously in Japan. This case is the second report of traumatic rupture of the bicuspid aortic valve.

The present observation illustrates an unusual complication occurring after stent-grafting (S-graft) for aortic isthmus rupture. A 22-year-old patient, treated by S-graft in the emergency department for traumatic aortic rupture, was readmitted 10 months later with pseudocoarctation syndrome. A membrane was found inside the stent-graft that had induced a pseudo-dissection, which caused the pseudocoarctation syndrome. Surgical treatment consisted of removing the stent-graft and membrane and replacing it with a vascular implant. The patient's clinical course was fair. The suggested mechanism was circumferential neoendothelialization of the stent-graft. Dehiscence caused the superior part of the membrane to drop into the lumen of the stent-graft creating a 'false channel' that compressed the 'true lumen' and induced 'pseudocoarctation' syndrome. The cause of the extensive neointimalization remains unexplained. Thoracic aortic stent-grafts require regular follow-up monitoring by angioscan or angio-magnetic resonance imaging.

Traumatic posterior dislocation of the elbow is often associated with significant morbidity and incomplete recovery. The aim of this study was to retrospectively analyse the outcome of 33 children (median age 10.8 years). Patients underwent reduction and assessment of stability under general anaesthesia. Pure dislocations (n=10) were immobilized, whereas unstable fractures (n=23) were stabilized. Refixation of ligaments was performed if stability was not achieved by fracture stabilization alone. Immobilization was continued for 26 (pure dislocations) or 35 days (associated injuries), respectively. Results were excellent (n=9) or good (n=1) after pure dislocation. Results were excellent (n=15), good (n=7) or poor (n=1) in children with associated injuries. Accurate diagnosis, concentric stable reduction of the elbow as well as stable osteosynthesis of displaced fractures are associated with good results in children with acute posterior elbow dislocations.

Gastric volvulus is a rare complication of diaphragmatic rupture. We report the case of an 82-year-old man who presented following an out-of-hospital cardiac arrest. Chest radiography and thoracic computed tomography revealed an acute gastric volvulus and a chronic diaphragmatic hernia containing transverse colon and abdominal viscera. He had complained of retching and associated epigastric pain prior to collapse, and had sustained a motorcycle accident approximately 60 years earlier. Insertion of a nasogastric tube was unsuccessful (completing Borchardt’s diagnostic triad) and his condition prevented both operative and endoscopic reduction of his volvulus. He died soon afterwards. PMID:25245717

This clinical practice guideline is based on a series of systematic reviews of published studies in the available literature on the diagnosis and treatment of acute Achilles tendon rupture. None of the 16 recommendations made by the work group was graded as strong; most are graded inconclusive; four are graded weak; two are graded as moderate strength; and two are consensus statements. The two moderate-strength recommendations include the suggestions for early postoperative protective weight bearing and for the use of protective devices that allow for postoperative mobilization.

A 75-year-old man complaining of acute abdominal pain, 1 month after elective surgical repair of an abdominal aortic aneurysm by an aortabi-iliac bypass graft, was referred and admitted to the emergency room. Imaging by sonography and computed tomography scan revealed a ruptured iliac pseudoaneurysm at the right iliac anastomotic site with associated large retroperitoneal hematoma. We inserted a self-expanding covered Z-stent graft by a transfemoral approach and the iliac anastomotic pseudoaneurysm was successfully excluded. Our case demonstrates the possibilities of an endovascular approach for providing a fast, efficient and less aggravating procedure in order to treat these life-threatening conditions.

In patients with an acute Achilles tendon rupture, it has not been possible to determine the superiority of a single specific treatment modality over other treatments with respect to symptoms and function. When several pertinent treatment protocols are available for an injury, it is of interest to understand how other variables, such as age, sex, or physical activity level, affect outcome to better individualize the treatment. To investigate predictors of both symptomatic and functional outcomes after an acute Achilles tendon rupture. Cohort study (Prognosis); Level of evidence, 2. Ninety-three patients (79 men and 14 women; mean age, 40 years) were evaluated prospectively at 3, 6, and 12 months. The main outcome measures in this study were the Achilles tendon Total Rupture Score (ATRS) for symptoms and maximum heel-rise height for function. The independent variables evaluated as possible predictors of outcome included treatment, sex, age, body mass index (BMI), physical activity level, symptoms, and quality of life. Treatment, age, BMI, physical activity level, heel-rise height at 6 months, and the ATRS at 3 months were eligible for further analysis. Only male sex was included for the prediction models. The 4 different multiple linear regression models (predicting the ATRS at 6 and 12 months and heel-rise height at 6 and 12 months) were significant (P < .001-.002), and the R (2) values for the models were 0.222 to 0.409. Surgical or nonsurgical treatment is a moderate predictor of symptoms and a weak predictor of heel-rise height after an acute Achilles tendon rupture. At the 6-month follow-up, surgical treatment was associated with a larger heel-rise height, but the opposite was seen at 12 months. Surgical treatment resulted in a lower degree of symptoms. Increasing age was a strong predictor of reduced heel-rise height, and an increase in age of 10 years reduced the expected heel-rise height by approximately 8%. A higher BMI was also a strong predictor of a

Traumatic rupture of the aorta is the second most common cause of death in closed chest injury. The latest findings of autopsy showed that 80% of lethal outcomes in aortic injury occur in the prehospital period. Taking into consideration the incidence and high rate of death prior to the diagnosis stage, aortic rupture in closed thoracic injury is an important problem. Due to the characteristic mechanism of the development (during sharp deceleration of the body) this type of traumatic lesion of the aorta became known as "deceleration syndrome". The most vulnerable to tension aortic portion is its neck where the mobile part of the thoracic aorta is connected to the fixed arch in the place of the arterial ligament attachment. Open surgical intervention in patients with severe closed chest injury (often concomitant injury) is associated with high mortality and complications. Currently endovascular prosthetic repair of the aorta is a method of choice at the primary stage of treatment of patients with aortic injury. In this article we present a rare case report of concomitant lesion of large vessels (the descending aortic portion and proper hepatic artery) in a patient with severe concomitant injury, as well as peculiarities of diagnosis and combined treatment (endovascular prosthetic repair of the aorta and hepatic artery with an aotovein).
Subclavian artery injuries represent an uncommon complication of blunt chest trauma, this structure being protected by subclavius muscle, the clavicle, the first rib, and the deep cervical fascia as well as the costo-coracoid ligament, a clavi-coraco-axillary fascia portion. Subclavian artery injury appears early after trauma, and arterial rupture may cause life-treatening haemorrages, pseudo-aneurysm formation and compression of brachial plexus. These clinical eveniences must be carefully worked out by accurate physical examination of the upper limb: skin color, temperature, sensation as well as radial pulse and hand motility represent the key points of physical examination in this setting. The presence of large hematomas and pulsatile palpable mass in supraclavicular region should raise the suspicion of serious vascular injury. Since the first reports of endovascular treatment for traumatic vascular injuries in the 90’s, an increasing number of vascular lesions have been treated this way. We report a case of traumatic subclavian arterial rupture after blunt chest trauma due to a 4 meters fall, treated by endovascular stent grafting, providing a complete review of the past twenty years’ literature.

Thirty six cases of traumatic rupture of the thoracic aorta (TRA) were diagnosed during the hours following the accident responsible. Rupture was situated at the aortic isthmus in 32 cases, the ascending aortic in 2 cases, the arch of the aorta in 1 case and the descending sub-isthmic aorta in 1 case. Ten patients had no rib fractures. In 16 patients not undergoing surgery before 20th hour after the trauma, 10 died of secondary rupture. The course of a TRA is thus unpredictable and it is of fundamental importance to make the diagnosis and undertake appropriate surgical treatment immediately. The essential clinical sign is a difference in blood pressure between the upper and lower limbs (6 6%). Radiological signs suggestive of TRA are, in a plain PA chest film : widening of the mediastinum (92 %), poor visibility of the knuckle of the aorta (89 %), left haemothorax (67 %), deviation of the trachea to the right (55 %) and lowering of the left main bronchus (47 %). The slightest suspicion of a TRA should lead to aortic angiography preferably via an arterial approach (humeral or femoral), or intravenously. Surgical treatment should not be delayed.

Objectives: Coagulopathy following major trauma is conventionally attributed to activation and consumption of coagulation factors. Recent studies have identified an acute coagulopathy present on admission that is independent of injury severity. We hypothesized that early coagulopathy is due to tissue hypoperfusion, and investigated derangements in coagulation associated with this. Methods: This was a prospective cohort study of major trauma patients admitted to a single trauma center. Blood was drawn within 10 minutes of arrival for analysis of partial thromboplastin and prothrombin times, prothrombin fragments 1+2, fibrinogen, thrombomodulin, protein C, plasminogen activator inhibitor-1, and d-dimers. Base deficit (BD) was used as a measure of tissue hypoperfusion. Results: A total of 208 patients were enrolled. Patients without tissue hypoperfusion were not coagulopathic, irrespective of the amount of thrombin generated. Prolongation of the partial thromboplastin and prothrombin times was only observed with an increased BD. An increasing BD was associated with high soluble thrombomodulin and low protein C levels. Low protein C levels were associated with prolongation of the partial thromboplastin and prothrombin times and hyperfibrinolysis with low levels of plasminogen activator inhibitor-1 and high d-dimer levels. High thrombomodulin and low protein C levels were significantly associated with increased mortality, blood transfusion requirements, acute renal injury, and reduced ventilator-free days. Conclusions: Early traumatic coagulopathy occurs only in the presence of tissue hypoperfusion and appears to occur without significant consumption of coagulation factors. Alterations in the thrombomodulin-protein C pathway are consistent with activated protein C activation and systemic anticoagulation. Admission plasma thrombomodulin and protein C levels are predictive of clinical outcomes following major trauma. PMID:17457176

Traumatic rupture of the aorta has a near 80% mortality. Most patients die on the site of the accident. Conventional surgical repair of these lesions has a high morbidity and mortality, generally associated to the severity of associated lesions. Over the last decade, endovascular treatment has become an effective therapeutic alternative. We report a 40 years old male, that suffered a traumatic rupture of the descending thoracic aorta in a car accident. A successful endovascular repair was performed, installing an endoprothesis on the site of the lesion, using a femoral artery approach. The patient had a good postoperative evolution and was discharged from the hospital once complete rehabilitation of his associated lesions was obtained.
Raised intracranial pressure (ICP) is an important complication of severe brain injury, and is associated with a high mortality rate. Barbiturates are believed to reduce intracranial pressure by suppressing cerebral metabolism, thus reducing cerebral metabolic demands and cerebral blood volume. However, barbiturates also reduce blood pressure and therefore may adversely effect cerebral perfusion pressure. To assess the effects of barbiturates in reducing raised intracranial pressure, mortality and morbidity in people with acute traumatic brain injury. To quantify any side effects resulting from the use of barbiturates. The review draws largely on the search strategy developed for the Cochrane Injuries Group as a whole. However, in addition the Cochrane Library was searched in December 1996 using the text terms "barbiturate*," "pentobarb*," "phenobarb*," "head," and "brain." An updated search was done in April 1999. Randomised or quasi randomised trials of any one or more of the barbiturate class of drugs (amobarbital, barbital, hexobarbital, mephobarbital, methohexital, murexide, pentobarbital, phenobarbital, secobarbital, thiobarbiturate) where study participants had a clinically diagnosed acute traumatic brain injury of any severity. The reviewer extracted the data and assessed the quality of allocation concealment in the trials. The pooled relative risk for death (barbiturate vs no barbiturate) was 1.09 (95%CI 0.81 to 1.47). The pooled effect of barbiturates on adverse neurological outcome, measured using the Glasgow Outcome Scale (death, persistent vegetative state or severe disability) was 1.15 (95% 0.81 to 1.64). Two studies examined the effect of barbiturate therapy on intracranial pressure. In the study by Eisenberger et al, a smaller proportion of patients in the barbiturate group had uncontrolled ICP (68% vs 83%). The relative risk for uncontrolled ICP was 0.81 (95%CI 0.62 to 1.06). Similarly, in the study by Ward et al, mean ICP was lower in the

To quantify any side effects resulting from the use of barbiturates. The following electronic databases were searched on 26 September 2012: CENTRAL (The Cochrane Library), MEDLINE (Ovid SP), PubMed, EMBASE (Ovid SP), PsycINFO (Ovid SP), PsycEXTRA (Ovid SP), ISI Web of Science: Science Citation Index and Conference Proceedings Citation Index-Science. Searching was not restricted by date, language or publication status. We also searched the reference lists of the included trials and review articles. We contacted researchers for information on ongoing studies. Randomised controlled trials of one or more of the barbiturate class of drugs, where study participants had clinically diagnosed acute traumatic brain injury of any severity. Two review authors screened the search results, extracted data and assessed the risk of bias in the trials. Data from seven trials involving 341 people are included in this review.For barbiturates versus no barbiturate, the pooled risk ratio (RR) of death from three trials was 1.09 (95% confidence interval (CI) 0.81 to 1.47). Death or disability, measured using the Glasgow Outcome Scale was assessed in two trials, the RR with barbiturates was 1.15 (95% CI 0.81 to 1.64). Two trials examined the effect of barbiturate therapy on ICP. In one, a smaller proportion of patients in the barbiturate group had uncontrolled ICP (68% versus 83%); the RR for uncontrolled ICP was 0.81 (95% CI 0.62 to 1.06).

ABSTRACT Joint injury causes post‐traumatic osteoarthritis (PTOA). About ∼50% of patients rupturing their anterior cruciate ligament (ACL) will develop PTOA within 1–2 decades of the injury, yet the mechanisms responsible for the development of PTOA after joint injury are not well understood. In this study, we examined whole joint gene expression by RNA sequencing (RNAseq) at 1 day, 1‐, 6‐, and 12 weeks post injury, in a non‐invasive tibial compression (TC) overload mouse model of PTOA that mimics ACL rupture in humans. We identified 1446 genes differentially regulated between injured and contralateral joints. This includes known regulators of osteoarthritis such as MMP3, FN1, and COMP, and several new genes including Suco, Sorcs2, and Medag. We also identified 18 long noncoding RNAs that are differentially expressed in the injured joints. By comparing our data to gene expression data generated using the surgical destabilization of the medial meniscus (DMM) PTOA model, we identified several common genes and shared mechanisms. Our study highlights several differences between these two models and suggests that the TC model may be a more rapidly progressing model of PTOA. This study provides the first account of gene expression changes associated with PTOA development and progression in a TC model. © 2016 The Authors.

In order to effectively respond to and minimize the psychological impact following disasters, such as radio-nuclear ones, it is essential to understand the mechanisms involved in such conditions and how to prevent and treat the psychological impacts, including those related to acute traumatic stress and its consequences across life span. Radio-nuclear emergencies may cause psychological traumatic stress, with its potentially significant consequences in mental health, with both short and long-term effects, which extend beyond the individuals directly affected. Ionizing radiation cannot be perceived by human senses and most people are unaware of the magnitude of its effects, which could result in feelings of helplessness and vulnerability. Those situations with a high degree of uncertainty, regarding potential future health effects, are more psychologically traumatic than others. The present century has witnessed a steady increase in the number of publications concerning the mental health impact of traumatic events, showing the need of increasing the study of traumatic stress and its impact on mental health. A prompt, planned and effective response to manage disaster-induced acute traumatic stress may prevent the evolutionary reactions of traumatic stress into disorders or even chronic stress diseases that can appear after a nuclear or radiological emergency.

Purpose. Traumatic rupture of the thoracic aorta secondary to blunt chest trauma is a life-threatening emergency and a common cause of death, usually following violent collisions. The objective of this retrospective report was to evaluate the efficacy of endovascular treatment of thoracic aortic disruptions with a single commercially available stent-graft. Methods. Nine men (mean age 29.5 years) were admitted to our institution between January 2003 and January 2006 due to blunt aortic trauma following violent motor vehicle collisions. Plain chest radiography, spiral computed tomography, aortography, and transesophageal echocardiography were used for diagnostic purposes in all cases. All patients were diagnosed with contained extramural thoracic aortic hematomas, secondary to aortic disruption. One patient was also diagnosed with a traumatic thoracic aortic dissection, secondary to blunt trauma. All subjects were poor surgical candidates, due to major injuries such as multiple bone fractures, abdominal hematomas, and pulmonary contusions. All repairs were performed using the EndoFit (LeMaitre Vascular) stent-graft. Results. Complete exclusion of the traumatic aortic disruption and pseudoaneurysm was achieved and verified at intraoperative arteriography and on CT scans, within 10 days of the repair in all patients. In 1 case the deployment of a second cuff was necessary due to a secondary endoleak. In 2 cases the left subclavian artery was occluded to achieve adequate graft fixation. No procedure-related deaths have occurred and no cardiac or peripheral vascular complications were observed within the 12 months (range 8-16 months) follow-up. Conclusions. This is the first time the EndoFit graft has been utilized in the treatment of thoracic aortic disruptions secondary to chest trauma. The repair of such pathologies is technically feasible and early follow-up results are promising.

Spontaneous splenic rupture, also referred to as atraumatic splenic rupture, is a rare but life-threatening emergency condition. Without timely diagnosis and treatment, the mortality rate of splenic rupture approaches 100%. The etiology of atraumatic splenic rupture varies; it is reportedly associated with neoplasms or splenic infection, but is rarely encountered in patients with both conditions. We herein report the case of a 58-year-old male patient with acute myeloid leukemia (AML) complicated by splenic tuberculosis (TB), who presented with spontaneous rupture of the spleen. Pathological examination of the resected spleen revealed multifocal granulomatosis with caseous necrosis. However, with timely diagnosis and surgical intervention, the patient recovered successfully and is currently on consolidation therapy. To the best of our knowledge, this is the first case of spontaneous splenic rupture in AML with splenic TB. The relevant literature on spontaneous splenic rupture was also reviewed and the potential etiology and treatment were discussed. PMID:28357096

Quadriceps tendon rupture is an uncommon injury. This disabling condition is the result of direct or indirect trauma. It requires surgical repair to avoid poor outcomes in cases of neglected or chronic rupture. In most acute cases, simple tendon suture or reinsertion is suitable for an extensor mechanism reconstruction of the knee joint. However, chronic lesions often require a tendon graft or flap reconstruction. We report a case of a 15-year-old male who was diagnosed with a chronic quadriceps rupture with a patellar superior pole fracture. We performed quadriceps reconstruction using tibialis anterior allograft tendon and additional screw fixation to reconstruct the extensor mechanism and recover knee joint range of motion to prevent a high-level functional restriction. The treatment was difficult and limited due to neglect for 9-months that led to ankylosis accompanied with nonunion of tibial fracture. Our surgical treatment using allograft tendon resulted in a very good outcome after 30 months of follow-up. PMID:27274474

Despite the high frequency of thoracic injuries secondary to traffic related accidents, the blunt cardiac valve rupture is extremely rare. Case report and review of the literature using PubMed/MEDLINE and EMBASE databases. A 38 year old female patient, victim of car accident was admitted. On primary survey the patient was conscious, cooperative and hemodynamic and respiratory stable. On secondary survey was found a bilateral open leg fracture and a seat belt sign. Whole body Computed Tomography revealed minimal haemorrhagic contusion of the cortex, left hemopneumothorax and right pneumothorax, bilateral rib fractures, liver contusion, left femoral neck fracture and fracture to the lumbar spinal column. After bilateral pleurostomy, the patient becomes hemodynamically unstable, but with no signs of external bleeding. The transthoracic echocardiography revealed an acute severe tricuspid regurgitation with hepatic veins reflux. After orthopaedic surgeries, the tricuspid valve rupture was managed by replacing the valve with a bioprostheses. The hospital stay was 122 days. Only a high index of suspicion may reveal blunt cardiac lesions as a cause for hemodynamic instability in acute setting. Celsius.

There are limited data regarding outcomes and return to sports after surgery for acute versus chronic proximal hamstring ruptures. Surgery for chronic proximal hamstring ruptures leads to improved outcomes and return to sports but at a lower level than with acute repair. Proximal hamstring reconstruction with an Achilles allograft for chronic ruptures is successful when direct repair is not possible. Cohort study; Level of evidence, 3. Between 2002 and 2012, a total of 72 patients with a traumatic proximal hamstring rupture (51 acute, 21 chronic) underwent either direct tendon repair with suture anchors (n = 58) or Achilles allograft tendon reconstruction (n = 14). Results from the Single Assessment Numeric Evaluation (SANE) for activities of daily living (ADL) and sports-related activities, Short Form-12 (SF-12), visual analog scale (VAS), and a patient satisfaction questionnaire were obtained. The mean time to surgery in the chronic group was 441.4 days versus 17.8 days in the acute group. At a mean follow-up of 45 months, patients with chronic tears had inferior sports activity scores (70.2% vs 80.3%, respectively; P = .026) and a trend for decreased ADL scores (86.5% vs 93.3%, respectively; P = .085) compared with those with acute tears. Patients with chronic tears, however, reported significant improvements postoperatively for both sports activity scores (30.3% to 70.2%; P < .01) and ADL scores (56.1% to 86.5%; P < .01). Greater than 5 to 6 cm of retraction in the chronic group was predictive of the need for allograft reconstruction (P = .015) and resulted in ADL and sports activity scores equal to those of chronic repair (P = .507 and P = .904, respectively). There were no significant differences between groups in SF-12, VAS, or patient satisfaction outcomes (mean, 85.2% satisfaction overall). Acute repair was superior to chronic surgery with regard to return to sports. Acute and chronic proximal hamstring repair and allograft reconstruction had favorable

Swan neck deformity (SND) can be the manifestation of an acute trauma. We present a case report of a young basketball player with an acute traumatic SND determined by the single ulnar oblique retinacular ligament rupture. The patient caught a ball directly upon the tip of his right's hand middle finger into extension. He immediately presented a SND with impossibility to actively flex the proximal interphalangeal joint (PIPJ), while preserving active flexion and extension of the distal interphalangeal joint (DIPJ). Hyperextension of PIPJ was reducible with passive mobilization, thus allowing full passive range of motion. The SND was seen to be caused by the lesion of the ulnar oblique retinacular ligament (ORL) on its distal insertion, with consequent dorsomedial migration of the ulnar lateral band. The early surgical distal reinsertion of the ORL allowed the restoration of the original kinematics of the finger flexion-extension.

Acute traumatic brain injury is a major cause of death and disability. Calcium channel blockers (calcium antagonists) have been used in an attempt to prevent cerebral vasospasm after injury, maintain blood flow to the brain, and so prevent further damage. To estimate the effects of calcium channel blockers in patients with acute traumatic brain injury, and in a subgroup of brain injury patients with traumatic subarachnoid haemorrhage. Handsearching and electronic searching for randomised controlled trials. Randomised controlled trials in patients with all levels of severity of clinically diagnosed acute traumatic brain injury. Two reviewers independently assessed the identified studies for eligibility and extracted data from each study. Summary odds ratios were calculated using the Mantel-Haenszel method. Six RCTs were identified as eligible for inclusion in the systematic review. The effect of calcium channel blockers on the risk of death was reported in five of the RCTs. The pooled odds ratio (OR) for the five studies was 0.91 (95% confidence interval [95%CI] 0.70-1.17). For the four RCTs that reported death and severe disability (unfavourable outcome), the pooled odds ratio was 0.85 (95%CI 0.68-1.07). In the two RCTs which reported the risk of death in a subgroup of traumatic subarachnoid haemorrhage patients, the pooled odds ratio was 0.59 (95%CI 0.37-0.94). Three RCTs reported death and severe disability as an outcome in this subgroup, and the pooled odds ratio was 0.67 (95%CI 0.46-0.98). This systematic review of randomised controlled trials of calcium channel blockers in acute traumatic head injury patients shows that considerable uncertainty remains over their effects. The effect of nimodipine in a subgroup of brain injury patients with subarachnoid haemorrhage shows a beneficial effect, though the increase in adverse reactions suffered by the intervention group may mean that the drug is harmful for some patients.

When a spontaneous abortion is followed by complicated bereavement, the primary care physician may not consider the diagnosis of acute stress disorder or post-traumatic stress disorder. The major difference between these two conditions is that, in acute stress disorder, symptoms such as dissociation, reliving the trauma, avoiding stimuli associated with the trauma and increased arousal are present for at least two days but not longer than four weeks. When the symptoms persist beyond four weeks, the patient may have post-traumatic stress disorder. The symptoms of distress response after spontaneous abortion include psychologic, physical, cognitive and behavioral effects; however, patients with distress response after spontaneous abortion often do not meet the criteria for acute or post-traumatic stress disorder. After spontaneous abortion, as many as 10 percent of women may have acute stress disorder and up to 1 percent may have post-traumatic stress disorder. Critical incident stress debriefing, which may be administered by trained family physicians or mental health practitioners, may help patients who are having a stress disorder after a spontaneous abortion.

Traumatic brain injury (TBI) is a leading cause of death and disability, and the identification of effective, inexpensive and widely practicable treatments for brain injury is of great public health importance worldwide. Progesterone is a naturally produced hormone that has well-defined pharmacokinetics, is widely available, inexpensive, and has steroidal, neuroactive and neurosteroidal actions in the central nervous system. It is, therefore, a potential candidate for treating TBI patients. However, uncertainty exists regarding the efficacy of this treatment. This is an update of our previous review of the same title, published in 2012. To assess the effects of progesterone on neurologic outcome, mortality and disability in patients with acute TBI. To assess the safety of progesterone in patients with acute TBI. We updated our searches of the following databases: the Cochrane Injuries Group's Specialised Register (30 September 2016), the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 9, 2016), MEDLINE (Ovid; 1950 to 30 September 2016), Embase (Ovid; 1980 to 30 September 2016), Web of Science Core Collection: Conference Proceedings Citation Index-Science (CPCI-S; 1990 to 30 September 2016); and trials registries: Clinicaltrials.gov (30 September 2016) and the World Health Organization (WHO) International Clinical Trials Registry Platform (30 September 2016). We included randomised controlled trials (RCTs) of progesterone versus no progesterone (or placebo) for the treatment of people with acute TBI. Two review authors screened search results independently to identify potentially relevant studies for inclusion. Independently, two review authors selected trials that met the inclusion criteria from the results of the screened searches, with no disagreement. We included five RCTs in the review, with a total of 2392 participants. We assessed one trial to be at low risk of bias; two at unclear risk of bias (in one multicentred trial the possibility of

A 45-year-old man presented with bilateral acute subdural hematomas (ASDHs) without subarachnoid hemorrhage (SAH). He was found comatose in a parked car. Computed tomography showed left frontal intracerebral hemorrhage (ICH) and bilateral ASDHs but no signs of SAH. Magnetic resonance angiography demonstrated an internal carotid artery dorsal wall aneurysm. Emergent surgical intervention was performed. However, he died of cerebral herniation 6 days later. We inferred that massive intracranial bleeding might have ruptured through the cortex and lacerated the arachnoid membrane. Aneurysm rupture generally results in unilateral SDH, whereas trauma is the usual cause of bilateral ASDHs with ICH. Our case suggests that ruptured aneurysm should be considered in patients with non-traumatic bilateral ASDHs without SAH.

To identify an appropriate diagnostic tool for the early diagnosis of acute traumatic coagulopathy and validate this modality through prediction of transfusion requirements in trauma hemorrhage. Prospective observational cohort study. Level 1 trauma center. Adult trauma patients who met the local criteria for full trauma team activation. Exclusion criteria included emergency department arrival >2 hrs after injury, >2000 mL of intravenous fluid before emergency department arrival, or transfer from another hospital. None. Blood was collected on arrival in the emergency department and analyzed with laboratory prothrombin time, point-of-care prothrombin time, and rotational thromboelastometry. Prothrombin time ratio was calculated and acute traumatic coagulopathy defined as laboratory prothrombin time ratio >1.2. Transfusion requirements were recorded for the first 12 hrs following admission. Three hundred patients were included in the study. Laboratory prothrombin time results were available at a median of 78 (62-103) mins. Point-of-care prothrombin time ratio had reduced agreement with laboratory prothrombin time ratio in patients with acute traumatic coagulopathy, with 29% false-negative results. In acute traumatic coagulopathy, the rotational thromboelastometry clot amplitude at 5 mins was diminished by 42%, and this persisted throughout clot maturation. Rotational thromboelastometry clotting time was not significantly prolonged. Clot amplitude at a 5-min threshold of ≤35 mm had a detection rate of 77% for acute traumatic coagulopathy with a false-positive rate of 13%. Patients with clot amplitude at 5 mins ≤35 mm were more likely to receive red cell (46% vs. 17%, p < .001) and plasma (37% vs. 11%, p < .001) transfusions. The clot amplitude at 5 mins could identify patients who would require massive transfusion (detection rate of 71%, vs. 43% for prothrombin time ratio >1.2, p < .001). In trauma hemorrhage, prothrombin time ratio is not rapidly available from

Cardiac ruptures after myocardial infarction are classified as ventricular free wall ruptures (FWR), ventricular septal ruptures (VSR), and papillary muscle ruptures (PMR). A combination of any two types of rupture is called "ventricular double rupture;" (VDR) and shows a specific clinical course. 3,284 patients with acute myocardial infarction (AMI) were admitted to the CCU of our hospital between April, 1973 and December, 2001, and 10 patients (8 males and 2 female, aged 54 through 82 years) with VDR were clinicopathologically evaluated. All were diagnosed as VDR consisting of FWR and VSR. VDR was observed in 0.30% of all patients with AMI, in 3.0% of those with FWR, and in 16.1% of those with VSR. The infarct site was anteroseptal in 3 patients, anterolateral in 3, inferior in 3, and posterolateral in 1. Two patients with inferior infarction complicated RV infarction and a patient with posterolateral infarction had healed inferior infarction. The risk factors related to VDR were age, a history of hypertension, increased sympathetic tone to improve hemodynamic aggravation after perforation, cardiotonic agents, thrombolytic agents, delayed reperfusion, right ventricular volume overload by shunt and re-infarction. However, these factors might have played only a subsidiary role. The most important factor in VDR was the pathological findings. The site of septal perforation was the apex close to the septum-free wall junction in 9 patients and the site of rupture was also apical in 8 patients. Four patients already had VSR on admission to our CCU. FWR developed soon after VSR was demonstrated in 4 patients. FWR and VSR occurred simultaneously in one patient. These results suggest that VSR in the apical region is a precursor of VDR and requires the earliest surgical treatment. Surgical treatment was carried out in the operating room in 5 patients and 3 (60.0%) of them survived for 4 months or more. Two patients with rupture incidentally detected during operation for VSR

Recently, we observed a case of lumbar artery injury after trauma, which was treated by endovascular embolization. A 67-year-old woman who was injured in a traffic accident was brought to the emergency room. She was conscious and her hemodynamic condition was stable, but she had paraplegia below L1 dermatome. Contrast-enhanced computed tomography scan of abdomen and pelvis revealed fracture dislocation of L3/4 along with retroperitoneal hematomas. However, there was no evidence of traumatic injury in both thoracic and abdominal cavity. At that time, her blood pressure suddenly decreased to 60/40 mmHg and her mental status deteriorated. Also, her hemoglobin level was 5.4 g/dl. While her hemodynamic condition stabilized with massive fluid resuscitation including blood transfusion, an angiography was immediately performed to look for and embolize site of retroperitoneal hemorrhage. On the angiographic images, there was an active extravasation from ruptured left 3rd lumbar artery, and we performed complete embolization with GELFOAM and coil. Lumbar artery injury after trauma is rare and endovascular treatment is useful in case of hemodynamic instability.

This study investigated the mechanisms of traumatic rupture of the aorta (TRA). Eight unembalmed human cadavers were tested using various dynamic blunt loading modes. Impacts were conducted using a 32-kg impactor with a 152-mm face, and high-speed seatbelt pretensioners. High-speed biplane x-ray was used to visualize aortic motion within the mediastinum, and to measure deformation of the aorta. An axillary thoracotomy approach was used to access the peri-isthmic region to place radiopaque markers on the aorta. The cadavers were inverted for testing. Clinically relevant TRA was observed in seven of the tests. Peak average longitudinal Lagrange strain was 0.644, with the average peak for all tests being 0.208 +/- 0.216. Peak intraluminal pressure of 165 kPa was recorded. Longitudinal stretch of the aorta was found to be a principal component of injury causation. Stretch of the aorta was generated by thoracic deformation, which is required for injury to occur. The presence of atherosclerosis was demonstrated to promote injury. The isthmus of the aorta moved dorsocranially during frontal impact and submarining loading modes. The aortic isthmus moved medially and anteriorly during impact to the left side. The results of this study provide a better understanding of the mechanisms associated with TRA, and can be used for the validation of finite element models developed for the examination and prediction of TRA.

General surgeons are often asked to evaluate acute abdominal pain which has an expanded differential diagnosis in women of childbearing age. Acute appendicitis accounts for many surgical emergencies as a common cause of nongynecologic pelvic pain. In some rare instances, acute appendicitis has been shown to occur simultaneously with a variety of gynecologic diseases. We report a case of concurrent acute appendicitis and ruptured ovarian endometrioma. PMID:28097032

Ventricular septal rupture (VSR) secondary to blunt chest trauma is rare and associated with a diverse range of symptoms and clinical courses as well as disease severity. We present a case of traumatic VSR in which rapid progression of heart failure was observed in spite of relatively low pulmonary to systemic blood flow (Qp/Qs) ratio. A 40-year-old male was transported to the emergency department approximately 12 h after blunt chest trauma. VSR was diagnosed by echocardiography, and right heart catheterization revealed a Qp/Qs ratio of 1.52. Although medical treatment was initially attempted, subsequent rapid progression of heart failure necessitated emergent surgical repair of VSR. Because small, asymptomatic VSR often close spontaneously, surgical repair of traumatic VSR is indicated when the shunt rate is relatively large or heart failure is present. However, the present case highlights the need to consider emergent surgical repair of traumatic VSR, even when the shunt rate is relatively small.

There has been considerable debate about the best treatment for acute rupture of the Achilles tendon. At our institution, a well-documented and structured program of nonoperative management of Achilles tendon rupture with use of casts and a removable orthosis was developed. We assessed the results in 140 consecutive patients with a complete rupture of the Achilles tendon who had been treated with our nonoperative regimen at our center between 1992 and 1998. Patients were evaluated on the basis of the subjective results and clinically with physiological testing. Overall, 56% of our patients had an excellent result; 30%, good; 12%, fair; and 2%, poor. The overall complication rate was 8%, with three complete and five partial tendon reruptures, two deep vein thromboses, and one temporary dropfoot. The results of our nonoperative orthotic treatment were better overall than published results of operative repair of acute Achilles tendon rupture. Our patients were quite satisfied with their treatment.

Distal biceps tendon ruptures are uncommon events in the adult population and exceedingly rare in the adolescent population. To the best of our knowledge, this is the first and only report of a distal biceps tendon rupture in an adolescent with a history of chronic corticosteroid suppression. We present a case of a 17-year-old male on chronic corticosteroid suppression who underwent a successful distal biceps tendon repair after an acute rupture following weightlifting. At the 1-year follow-up, the patient reports full range of motion and strength, and is able to return to his preinjury activity level with sports and weightlifting. Acute distal biceps ruptures are uncommon injuries in the pediatric population, but may occur in conjunction with chronic corticosteroid use. Anatomic repair, when possible, can restore function and strength. level IV, case report.

Rupture of Achilles tendon (AT) is an uncommon complication of treatment with fluoroquinolones. We describe a case of bilateral tendinosis and rupture of the right AT in a patient who began levofloxacin treatment for community acquired pneumonia. Sonography showed thickening and hypoecogenicity of both AT and complete rupture and separation of the right Achilles tendon.

To evaluate the outcome after percutaneous repair followed by accelerated rehabilitation for acute Achilles tendon ruptures. 21 men and 9 women (mean age, 41 years) underwent percutaneous repair by a single senior surgeon for acute Achilles tendon ruptures, followed by early weight bearing and accelerated rehabilitation. Outcome measures included the Achilles tendon re-rupture rate, the Achilles tendon total rupture score (ATRS) at 3 and 6 months, the incidence of sural nerve injury, wound infection, wound dehiscence, patient satisfaction, and the time to return to pre-rupture activity. The mean follow-up period was 12.5 months. The mean ATRS score improved from 57.65 at 3 months to 86.95 at 6 months (p<0.001). No patient had intra-operative complications, tendon re-rupture, sural nerve injury, wound dehiscence, or deep infection. Two patients developed a superficial wound infection, which was resolved with oral flucloxacillin. Two patients had a mass at the transverse incision, but neither had any symptoms or functional restriction. All patients were able to bear full weight comfortably without the walker boot at 8 weeks, and return to their work by 3 months. The mean time to return to pre-rupture activity, including sports, was 10.4 months. The mean satisfaction rate was 87% at 6 months. Percutaneous repair of the Achilles tendon followed by early weight bearing and accelerated rehabilitation achieves good functional outcome.

Traumatic spinal cord injury requires a multidisciplinary approach both for specialized treatment of the acute phase and for dealing with the secondary complications. A suspicion or diagnosis of spinal cord injury is the first step for a correct management. A review is made of the prehospital management and characteristics of the acute phase of spinal cord injury. Respiratory monitoring for early selective intubation, proper identification and treatment of neurogenic shock are essential for the prevention of secondary spinal cord injury. The use of corticosteroids is currently not a standard practice in neuroprotective treatment, and hemodynamic monitoring and early surgical decompression constitute the cornerstones of adequate management. Traumatic spinal cord injury usually occurs as part of multiple trauma, and this can make diagnosis difficult. Neurological examination and correct selection of radiological exams prevent delayed diagnosis of spinal cord injuries, and help to establish the prognosis.

We retrospectively reviewed acute cervical cord injury after minor trauma in 10 patients with os odontoideum. Their clinical history, neurological symptoms, radiological investigations, follow-up period, American Spinal Injury Association impairment classification and motor score were reviewed. Before their traumatic injury, three patients were asymptomatic and seven reported myelopathic symptoms, including four patients with neck pain, two patients with unsteadiness and one patient with dizziness. Falls were the most common cause of injury (n=6), followed by minor motor vehicle accidents (n=3) and assault (n=1). MRI and dynamic cervical lateral radiographs showed that all patients had atlantoaxial instability and cord compression. Most patients had spinal cord thinning and hyperintensity on T2-weighted MRI. Spinal cord compression was posterior (n=5), or both anterior and posterior (n=5). All patients underwent posterior rigid screw fixation and fusion, including atlantoaxial fusion (n=8) and occipitocervical fusion (n=2). We conclude that patients with asymptomatic or myelopathic atlantoaxial instability secondary to os odontoideum are at risk for acute spinal cord injury after minor traumatic injury. Fixation and fusion should be undertaken as prophylactic treatment for patients at risk of developing myelopathy and to avoid the neurological deterioration associated with acute traumatic cervical cord injury.

Population-based incidence rates and trends of acute Achilles tendon ruptures are not known. It is also not known whether recent high-quality randomized controlled trials not favoring surgery have had an effect on treatment protocols. To assess the incidence of acute Achilles tendon ruptures in Sweden and to examine the trends in surgical treatment. Descriptive epidemiology study. We conducted a nationwide registry-based study including all adult (≥18 years of age) inpatient and outpatient hospital visits because of an acute Achilles tendon rupture in Sweden between 2001 and 2012. We identified a total of 27,702 patients (21,979 men, 79%) with acute Achilles tendon ruptures between 2001 and 2012. In 2001, the sex-specific incidence of acute Achilles tendon ruptures was 47.0 (per 100,000 person-years) in men and 12.0 in women. In 2012, the corresponding values were 55.2 in men and 14.7 in women, with an increase of 17% in men and 22% in women. The proportion of surgically treated patients declined from 43% in 2001 to 28% in 2012 in men and from 34% in 2001 to 22% in 2012 in women. The incidence of acute Achilles tendon ruptures in Sweden is increasing. The most probable reason for this increase is the rise in the number of older adults participating in high-demand sports. The proportion of surgically treated patients is decreasing most likely because of recent high-quality randomized controlled trials and their meta-analyses supporting similar results between surgical and nonsurgical approaches. © 2014 The Author(s).

Objective Clinical observations report excessive sleepiness immediately following traumatic brain injury (TBI); however, there is a lack of experimental evidence to support or refute the benefit of sleep following a brain injury. The aim of this study is to investigate acute post-traumatic sleep. Methods Sham, mild or moderate diffuse TBI was induced by midline fluid percussion injury (mFPI) in male C57BL/6J mice at 9:00 or 21:00 to evaluate injury-induced sleep behavior at sleep and wake onset, respectively. Sleep profiles were measured post-injury using a non-invasive, piezoelectric cage system. In separate cohorts of mice, inflammatory cytokines in the neocortex were quantified by immunoassay, and microglial activation was visualized by immunohistochemistry. Results Immediately after diffuse TBI, quantitative measures of sleep were characterized by a significant increase in sleep (>50%) for the first 6 hours post-injury, resulting from increases in sleep bout length, compared to sham. Acute post-traumatic sleep increased significantly independent of injury severity and time of injury (9:00 vs 21:00). The pro-inflammatory cytokine IL-1β increased in brain-injured mice compared to sham over the first 9 hours post-injury. Iba-1 positive microglia were evident in brain-injured cortex at 6 hours post-injury. Conclusion Post-traumatic sleep occurs for up to 6 hours after diffuse brain injury in the mouse regardless of injury severity or time of day. The temporal profile of secondary injury cascades may be driving the significant increase in post-traumatic sleep and contribute to the natural course of recovery through cellular repair.

A patient with traumatic thoracic injury and hypovolemic shock is presented to stress important differences in preoperative and postoperative aortic diameters. The patient had a blood pressure of 80/40 mm Hg. A diagnostic computed tomography angiography revealed a rupture of the thoracic aorta, and a thoracic endograft was sized based on these data. However, the postoperative computed tomography angiography (Riva-Rocci, 164/70 mm Hg) showed an increase in aortic diameters of about 30% at multiple levels. In this patient, with rupture of the thoracic aorta and hypovolemia, the aortic diameter was significantly decreased. This indicates that adequate preoperative sizing for endovascular repair of vascular pathology in patients in shock is complicated.

Spontaneous pure acute subdural haematoma (ASDH) without intraparenchymal or subarachnoid haemorrhage caused by a ruptured cerebral aneurysm is extremely rare. To our knowledge, the present case is the first report of an internal carotid artery bifurcation aneurysm presenting as pure ASDH. Suitable diagnostic investigations and therapeutic strategies are discussed. Arterial origin of bleeding should be considered in all cases of non-traumatic ASDH and a vascular anomaly has to be excluded. The neurological status on admission dictates the appropriate timing and methodology of the neuroradiological investigations.

Twenty four cases with myocardial rupture among 259 patients with autopsy after death due to myocardial infarction, were compared with patients with acute myocardial infarction and death secondary to other causes. Myocardial rupture occured during the first 72 hours in 58% of the patients and all cases within the first five days. Two thirds of the patients were males and 46% were 70 years of age. There were 24 myocardial ruptures (9.5%). Previous history of arterial hypertension and un-remittent anginal pain were predisposing factors for rupture (p=0.05). Other previously reported bad prognostic factors such as persistent hipertension after acute infarction, severe exercise before infarction and history of Diabetes Mellitus were not statistically significant in this study. Ruptured myocardium was not influenced by a previous history of myocardial infarction, hospitalization delay in the C.C.U., administration of anticoagulants, digitalis or pressor amines. There was no significant difference among the groups compared in enzyme curves or magnitude of leucocytosis. Electromechanic dissociation, sinus bradycardia, nodal rhythm followed by idioventricular rhythm and asystole, were observed following myocardial rupture.

Distal biceps tendon (DBT) ruptures are infrequent injuries that result in pain, weakness, and cosmetic deformity. Severe retraction of the ruptured DBT can occur at the time of injury, or in chronic neglected ruptures, and surgical exposure is performed using a single incision or a 2-incision technique. The technique presented here describes an endoscopic approach using 3 portals that provide access to the retracted DBT, biceps sheath, and radial tuberosity. Preoperative sonographic localization of the retracted DBT and neurovascular structures is used to guide portal placement. The parabiceps portal is used for visualization of the biceps sheath remnant, and the midbiceps portal is used to visualize and retrieve the retracted tendon in the arm. The retracted DBT is shuttled through the biceps sheath into the upper forearm, and 2 suture anchors are passed into the radial tuberosity under direct endoscopic vision. The DBT is whipstitched via the distal anterior portal, and nonsliding knots are tied to securely reattach the DBT to the prepared radial tuberosity.

Acute traumatic tear of the thoracic aorta is a severe injury with a high mortality rate. This condition requires expeditious evaluation and prompt surgical intervention in order to improve patient survival. The experience at the authors' institution from 1971 to 1987 includes 41 patients who sustained acute traumatic tear of the thoracic aorta and reached the hospital alive. The purpose of the study was to evaluate the surgical management of this injury with regards to mortality rate and the incidence of spinal cord injury. Five patients died from exsanguination before definitive repair could be undertaken. Thirty-six patients had repair of traumatic aortic tear in the area of the isthmus. Nine patients were operated upon with the clamp and sew technique, 20 patients had a heparin-bonded shunt placed, and seven patients were treated by repair with cardiopulmonary bypass. There were five operative deaths that were not related to the technique employed. Two patients without preoperative evidence of spinal cord injury developed paraparesis. No patient had postoperative paraplegia. Despite rapid transport, expeditious evaluation, and emergency thoracotomy, some patients die from exsanguination prior to definitive repair. Even with the provision of distal aortic perfusion during clamping, the risk of spinal cord injury is not eliminated. PMID:3389938

Acute intraperitoneal rupture is a rather rare complication of hepatic hydatid cysts; anaphylaxis and sudden death have frequently been reported in such cases. In the present report we are presenting a case of acute traumatic intraperitoneal rupture of a huge hydatid cyst to which the patient showed no hypersensitivity reactions.

Patellar dislocation usually occurs to the lateral side, leading to ruptures of the medial patellofemoral ligament (MPFL) in about 90 % of all cases. Reliable prognostic factors for the stability of the patellofemoral joint after MPFL surgery and satisfaction of the patient have not been established as yet. This multicentric study retrospectively included 40 patients with a mean age of 22.4 ± 8.1 years (range 9-48) from 5 German Trauma Departments with first-time traumatic patellar dislocation and operative treatment. Surgery was limited to soft tissue repairs, and a preoperative magnetic resonance imaging (MRI) was performed in all cases. Evaluation of the MRI included sulcus angle, dysplasia of the trochlea, depth and facet asymmetry of the trochlea, Insall-Salvati index, Tibial tuberosity to trochlear groove (TTTG) distance, and rupture patterns of the MPFL. Patients were interrogated after 2 years about recurrent dislocation, satisfaction, and the Kujala score. Trochlea facet asymmetry was significantly lower in patients with redislocation (23.5 ± 18.8) than in patients without redislocation (43.1 ± 16.5, p = 0.03). Patients with a patellar-based rupture were significantly younger (19.5 ± 7.2 years) than patients without patellar-based rupture (25.4 ± 8.1 years, p < 0.02). Patients with femoral-based ruptures were significantly older (25.7 ± 9.2 years) than patients without femoral-based rupture (19.7 ± 6.1 years, p < 0.02), and had a significantly higher TTTG distance (10.2 ± 6.9 vs. 4.5 ± 5.5, p < 0.02). Patients with incomplete ruptures of the MPFL had a significantly lower Insall-Salvati index (1.2 ± 0.2 vs. 1.4 ± 0.2, p = 0.05). The Kujala score in patients with redislocations was significantly lower (81.0 ± 10.5 points) than in patients without redislocation (91.9 ± 9.2 points, p < 0.02). Younger patients more often sustain patellar-based ruptures following first-time traumatic patella dislocation

Multiple traumatic and non-traumatic adrenal emergencies are occasionally encountered during the cross-sectional imaging of emergency department patients. Traumatic adrenal hematomas are markers of severe polytrauma, and can be easily overlooked due to multiple concomitant injuries. Patients with non-traumatic adrenal emergencies usually present to an emergency department with a non-specific clinical picture. The detection and management of adrenal emergencies is based on cross-sectional imaging. Adrenal hemorrhage, adrenal infection, or rupture of adrenal neoplasm require immediate detection to avoid dire consequences. More often however, adrenal emergencies are detected incidentally in patients being investigated for non-specific acute abdominal pain. A high index of suspicion is required for the establishment of timely diagnosis and to avert potentially life-threatening complications. We describe cross-sectional imaging findings in patients with traumatic and non-traumatic adrenal hemorrhage, adrenal infarctions, adrenal infections, and complications of adrenal masses.

Fever frequently presents during recovery from traumatic brain injury (TBI). Elevated body temperature may result from ensuing infection, thrombophlebitis, drug reaction, or a defect in the central thermoregulatory system such as seen in post-traumatic hyperthermia (PTH). Typically, the diagnosis of PTH follows only after thorough investigation. Literature supports the theory that the febrile TBI patient, lacking a documented source, has central hyperthermia. The purpose of this study was to determine the incidence of PTH in the acute rehabilitation setting. We reviewed a consecutive series of 84 TBI patients participating in a rehabilitation programme. Four per cent of the patients in this study met our criteria for PTH. We describe a fever protocol that should aid the physician in diagnosis and treatment of the febrile TBI patient. Proposed mechanisms involved in thermoregulation are discussed.

To compare the effectiveness of tenocutaneous suture and conventional Kessler suture techniques in treating acute closed Achilles tendon rupture. A total of 33 patients with acute closed Achilles tendon rupture who were admitted to our hospital from February 1998 to December 2008 underwent repair with either a tenocutaneous suture or Kessler suture technique. All patients were followed up for 1-5 years (mean, 3 years). According to the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale, the excellence rate was 91% in the Kessler suture group and 98% in the tenocutaneous suture group, with a significant difference between groups. Our tenocutaneous suture technique is an effective method for treating Achilles tendon rupture. It has certain advantages compared with the conventional incision method and is worthy of wide clinical application. Copyright © 2014 European Foot and Ankle Society. Published by Elsevier Ltd.

The optimal treatment for acute Achilles tendon ruptures is still an ongoing debate. Acute ultrasonography (US) investigation to measure the diastasis between the tendon ends has previously been used to classify acute Achilles tendon ruptures; however, no study has used US to predict reruptures and functional outcomes. To investigate whether acute US can be used to predict the risk of reruptures and outcomes after treatment of an acute Achilles tendon rupture. Cohort study; Level of evidence, 2. Forty-five patients (37 men, 8 women) with a mean age of 39 ± 9.2 years (range, 23-59 years) from a cohort of 97 patients participating in a randomized controlled study comparing surgical and nonsurgical treatment were included. US was performed within 72 hours from the index injury. Diastasis between the tendon ends was documented. Reruptures were documented, and the patients' functional outcomes were measured 12 months after injury. Patients with a diastasis of >10 mm treated nonsurgically had a higher degree of rerupture. In the nonsurgically treated group, 3 of 4 patients with a diastasis of >10 mm suffered from rerupture (P < .001). Moreover, in the nonsurgical group, there was significantly worse outcomes in patients with a diastasis of >5 mm in terms of patient-reported outcomes using the Achilles tendon Total Rupture Score (ATRS) (P = .004) and heel-rise height at 12 months (P = .048) compared with the group with a lesser degree of tendon separation. US may be a useful tool to predict the risk of rerupture and greater degree of functional deficit. It may be an important measure in a clinical treatment algorithm for deciding whether a patient will benefit from surgical intervention after an acute Achilles tendon rupture.

While elderly patients account for only 10-12% of all trauma victims, they consume 25% of trauma-related health care resources, with higher rates of mortality and complication. Presently described is the case of an elderly patient who presented to the emergency department (ED) following mild thoracic trauma, with previous history of gastric pull-up surgery. The patient had consulted another facility 48 hours earlier and was prescribed analgesia and x-ray follow-up for a mechanical fall and pain in the lower rib cage. At arrival, the patient complained of increasing dyspnea and pain at the right hemithorax. X-ray showed right hemithorax effusion, and contrast computed tomography (CT) demonstrated a large amount of contrast filling the pleural space and a relatively small point of gastric pull-up rupture in the stomach. The patient was referred to the cardiothoracic unit, but was unresponsive upon arrival and died. The aim of the present report was to raise the index of clinical suspicion of traumatic rupture of the gastric pull-up following traumatic chest injury, and to affirm that contrast CT should be the gold standard for diagnosis.

Introduction Coil embolization of ruptured aneurysms has become the standard treatment in many situations. However, certain aneurysm morphologies pose technical difficulties and may require the use of adjunctive devices. Objective To present our experience with the pCONus, a new neck bridging device, as an adjunct to coil embolization for acutely ruptured aneurysms and discuss the technical success, angiographic and clinical outcomes. Methods We conducted a retrospective review of our database of prospectively collected data to identify all patients who presented with acute subarachnoid hemorrhage that required adjunctive treatment with the pCONus in the acute stage. We searched the database between April 2011 and April 2016. Results 21 patients were identified (13 male, 8 female) with an average age of 54.6 years (range 31–73). 8 aneurysms were located at the basilar artery tip, 7 at the anterior communicating artery, 4 at the middle cerebral artery bifurcation, 1 pericallosal, and 1 basilar fenestration. 61.8% patients achieved modified Raymond–Roy classification I or II at immediate angiography, with 75% of patients having completely occluded aneurysms or stable appearance at initial follow-up. There were no repeat aneurysmal ruptures and two device-related complications (no permanent morbidity). Four patients in our cohort died. Conclusions Use of the pCONus is safe and effective in patients with acutely ruptured aneurysms and carries a high rate of technical success. PMID:27411859

A 61-year-old female patient presented with sub acute myocardial infarction with an occluded right coronary artery on invasive evaluation and a ventricular septal rupture on echocardiogram. Cardiac computed tomography (CT) was performed to better define the septal anatomy. As the anatomy on cardiac CT was considered unfavorable for percutaneous intervention, the patient underwent successful surgical repair.

The optimum treatment of acute total Achilles tendon rupture remains controversial. In the present study, the outcomes of surgical and nonsurgical treatment in a large number of patients were compared on the basis of patient age and sex. The records of all 487 patients with an acute total Achilles tendon rupture that had occurred between 2002 and 2006 and had been treated at one of two university hospitals in Sweden were manually reviewed. Surgical treatment was primarily used at Hospital 1, whereas nonoperative functional treatment was primarily used at Hospital 2. At one to seven years after the rupture, the majority of the patients were evaluated for complications, the Achilles Tendon Total Rupture Score was calculated, a heel-raise test was performed, and calf circumference was measured. The outcomes of surgical and nonsurgical treatment were compared on the basis of patient age and sex. The mean age at the time of the injury was forty-five years. In the surgical treatment group at Hospital 1, six (3%) of 201 patients had a re-rupture and three (1.5%) had an infection. In the nonsurgical treatment group at Hospital 2, the rate of re-rupture rate was 6.6% (fifteen of 227). When the results for the surgical treatment group at Hospital 1 were compared with those for the nonsurgical treatment group at Hospital 2, there was no significant difference in terms of the mean Achilles Tendon Total Rupture Score (81.7 compared with 78.9; p = 0.1), but both the difference in the heel-raise test (p = 0.01) and the difference in calf circumference (1.4 compared with 2.0 cm; p = 0.01) reached significance in favor of surgery. Nonsurgically managed female patients showed significant worsening of the Achilles Tendon Total Rupture Score and heel-raise test with increasing age at the time of injury. The good Achilles Tendon Total Rupture Score in the nonsurgically managed group, together with the relatively low rate of re-ruptures and other complications in these patients, makes

The aim of this study was to report the frequency, patient and lesion-related characteristics, and outcomes of subclinical, nonculprit plaque ruptures in the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study. Plaque rupture and subsequent thrombosis is the most common cause of acute coronary syndrome (ACS). Secondary, subclinical, nonculprit plaque ruptures have been seen in both stable patients and patients with ACS; however, reports of the natural history of these secondary plaque ruptures are limited. After successful stenting in 697 patients with ACS, 3-vessel grayscale and intravascular ultrasound virtual histology (IVUS-VH) was performed in the proximal-mid segments of all 3 coronary arteries as part of a prospective multicenter study. Among 660 patients with complete IVUS data, 128 plaque ruptures were identified in 105 nonculprit lesions in 100 arteries from 93 patients (14.1%). Although the minimum lumen area (MLA) was similar, the plaque burden was significantly greater in nonculprit lesions with a plaque rupture compared with nonculprit lesions without a plaque rupture (66.0% [95% confidence interval: 64.5% to 67.4%] vs. 56.0% [95% confidence interval: 55.6% to 56.4%]; p < 0.0001). IVUS-VH analysis revealed that a nonculprit lesion with a plaque rupture was more often classified as a fibroatheroma than a nonculprit lesion without a plaque rupture (77.1% vs. 51.4%; p < 0.0001). Independent predictors of a plaque rupture were lesion length (per 10 mm; odds ratio: 1.30; p < 0.0001), plaque burden at the MLA site (per 10%; odds ratio: 2.56; p < 0.0001), vessel area at the MLA site (per 1 mm(2); odds ratio: 1.13; p < 0.0001), and VH-thin-cap fibroatheroma (odds ratio: 1.80; p = 0.016). During 3 years of follow-up, the incidence of overall major adverse cardiac events did not differ significantly between the patients with and patients without subclinical, nonculprit plaque ruptures.

The optimal treatment for acute Achilles tendon rupture (ATR) is continuously debated. Recent studies have proposed that the choice of either operative or non-operative treatment may not be as important as rehabilitation, suggesting that functional rehabilitation should be preferred over traditional immobilization. The purpose of this meta-analysis of randomized controlled trials (RCTs) was to compare functional rehabilitation to immobilization in the treatment of ATR. This meta-analysis was conducted using the databases: PubMed, EMBASE, Rehabilitation and Sports Medicine Source, AMED, CINAHL, Cochrane Library and PEDro using the search terms: "Achilles tendon," "rupture," "mobilization" and "immobilization". Seven RCTs involving 427 participants were eligible for inclusion, with a total of 211 participants treated with functional rehabilitation and 216 treated with immobilization. Re-rupture rate, other complications, strength, range of motion, duration of sick leave, return to sport and patient satisfaction were examined. There were no statistically significant differences between groups. A trend favoring functional rehabilitation was seen regarding the examined outcomes. Functional rehabilitation after acute Achilles tendon rupture does not increase the rate of re-rupture or other complications. A trend toward earlier return to work and sport, and increased patient satisfaction was found when functional rehabilitation was used. The present literature is of low-to-average quality, and the basic constructs of the examined treatment and study protocols vary considerably. Larger, randomized controlled trials using validated outcome measures are needed to confirm the findings. II.

We present a patient with slow rupture of hydatid cyst into the peritoneal cavity, presenting as massive abdominal distension and respiratory embarrassment. On paracentesis, no fluid could be drained. A small lateral incision was made under local anaesthesia to drain the 'ascites', but daughter cysts typical of hydatid came out. On laparotomy, there was a cyst in the right lobe of liver which had ruptured into the peritoneal cavity leading to secondary echinococcosis.

Coagulation factor XI is proposed as therapeutic target for anticoagulation. However, it is still unclear whether the antithrombotic properties of factor XI inhibitors influence atherosclerotic disease and atherothrombosis. Our aim is to investigate whether factor XI antisense oligonucleotides could prevent thrombus formation on acutely ruptured atherosclerotic plaques. Atherosclerotic plaques in the carotid arteries of Apoe(-/-) mice were acutely ruptured using ultrasound. The subsequent thrombus formation was visualized and quantified by intravital microscopy and immunohistochemistry. Mice were pretreated with either factor XI antisense or nonsense oligonucleotides (50 mg/kg) to lower factor XI plasma levels. A tail bleeding assay was used to determine the safety. On plaque rupture, initial platelet adhesion and platelet plug formation were not impaired in animals treated with factor XI antisense oligonucleotides. However, the ensuing thrombus formation and fibrin deposition were significantly lower after 5 to 10 minutes (P<0.05) in factor XI antisense oligonucleotide-treated animals without inducing a bleeding tendency. Furthermore, thrombi from antisense-treated animals were less stable than thrombi from placebo-treated animals. Moreover, macrophage infiltration and collagen deposition were lower in the carotid arteries of factor XI antisense-treated animals. No neutrophils were present. Factor XI antisense oligonucleotides safely prevent thrombus formation on acutely ruptured atherosclerotic plaques in mice. Furthermore, perturbed carotid arteries from factor XI antisense-treated animals show a less severe inflammatory response. © 2014 American Heart Association, Inc.

This case demonstrates a rare variation in the pattern of injury and the presentation of acute lateral compartment syndrome of the leg. Although uncommon, lateral compartment syndrome of the leg after an ankle inversion leading to peroneus longus muscle rupture has been previously documented. This case was unusual because there was no overt ankle injury and the patient was able to continue physical activity, in spite of a significant rupture of the peroneus longus muscle that was determined later. This case highlights the necessary vigilance clinicians must maintain when assessing non-contact injuries in patients with possible compartment syndrome.

Traumatic brain injury (TBI) is a major cause of mortality and disability worldwide. We validated the utility of plasma metabolomics analysis in the clinical diagnosis of acute TBI in a rat model of controlled cortical impact (CCI) using gas chromatography/mass spectrometry (GC/MS). Thirty Sprague-Dawley rats were randomly divided into two groups of 15 rats each: the CCI group and sham group. Blood samples were obtained from the rats within the first 24 h after TBI injury. GC/MS measurements were performed to evaluate the profile of acute TBI-induced metabolic changes, resulting in the identification of 45 metabolites in plasma. Principal component analysis, partial least squares-discriminant analysis, orthogonal partial least square discriminant analysis using hierarchical clustering and univariate/multivariate analyses revealed clear differences in the plasma metabolome between the acute CCI group and the sham group. CCI induced distinctive changes in metabolites including linoleic acid metabolism, amino acid metabolism, galactose metabolism, and arachidonic acid metabolism. Specifically, the acute CCI group exhibited significant alterations in proline, phosphoric acid, β-hydroxybutyric acid, galactose, creatinine, L-valine, linoleic acid and arachidonic acid. A receiver operating characteristic curve analysis showed that the above 8 metabolites in plasma could be used as the potential biomarkers for the diagnosis of acute TBI. Furthermore, this study is the first time to identify the galactose as a biomarker candidate for acute TBI. This comprehensive metabolic analysis complements target screening for potential diagnostic biomarkers of acute TBI and enhances predictive value for the therapeutic intervention of acute TBI.

Traumatic subdural haematomas often require emergency surgical evacuation. Spontaneous resolution of traumatic acute subdural haematomas (TASDH) is under-reported. Two patients are described with spontaneous resolution of TASDH correlating with previous reports. A discussion is presented on the clinical, pathological and radiological features of TASDH. A review of the literature was performed using PubMed (Medline), Embase, and Cochrane Library for similar cases. A total 21 articles were included, involving 27 cases well detailed of TASDH with spontaneous resolution or neurological and radiological improvement in less than 24 h. There are two main mechanisms for the spontaneous resolution of acute subdural haematomas: dilution in subarachnoid space and redistribution of the haematoma in the subdural space. The primary radiological characteristic of these lesions is a hypodense rim on the outer surface of the clot. Spontaneous resolution of TASDH is unusual. Clinical and radiological surveillance is essential for appropriate management of these patients. Copyright © 2015 Sociedad Española de Neurocirugía. Published by Elsevier España.

We report the case of a patient with acute exacerbation of chronic pancreatitis and he suffered an atraumatic splenic rupture. Splenic rupture not associated with trauma is a rare entity that can occurs in normal spleen (spontaneous) or damaged spleen (pathological). This entity may be associated with local inflammatory processes, such as pancreatitis. Ultrasound is a non-invasive technique which is used in unstable patients. CT is useful for making a diagnosis of extension in patients with hemodynamic stability. Atraumatic splenic rupture as a complication of chronic pancreatitis is an unusual disease that requires a high index of suspicion which allows us an early diagnosis because it is a treatable entity that compromises the patient's life.

Left ventricular free wall rupture is a rare, but occasionally lethal, complication after acute myocardial infarction (AMI). This case report describes a patient who presented with cardiogenic shock due to oozing-type rupture secondary to AMI and successfully underwent percutaneous intrapericardial fibrin-glue injection therapy. Cardiac magnetic resonance imaging demonstrated the thin layer of fibrin that covered the ruptured infarct myocardium immediately after fibrin-glue injection and its disappearance without any complications at 6 months.

Background and Objectives We assessed plaque erosion of culprit lesions in patients with acute coronary syndrome in real world practice. Subjects and Methods Culprit lesion plaque rupture or plaque erosion was diagnosed with optical coherence tomography (OCT). Intravascular ultrasound (IVUS) was used to determine arterial remodeling. Positive remodeling was defined as a remodeling index (lesion/reference EEM [external elastic membrane area) >1.05. Results A total of 90 patients who had plaque rupture showing fibrous-cap discontinuity and ruptured cavity were enrolled. 36 patients showed definite OCT-plaque erosion, while 7 patients had probable OCT-plaque erosion. Overall, 26% (11/43) of definite/probable plaque erosion had non-ST elevation myocardial infarction (NSTEMI) while 35% (15/43) had ST elevation myocardial infarction (STEMI). Conversely, 14.5% (13/90) of plaque rupture had NSTEMI while 71% (64/90) had STEMI (p<0.0001). Among plaque erosion, white thrombus was seen in 55.8% (24/43) of patients and red thrombus in 27.9% (12/43) of patients. Compared to plaque erosion, plaque rupture more often showed positive remodeling (p=0.003) with a larger necrotic core area examined by virtual histology (VH)-IVUS, while negative remodeling was prominent in plaque erosion. Overall, 65% 28/43 of plaque erosions were located in the proximal 30 mm of a culprit vessel-similar to plaque ruptures (72%, 65/90, p=0.29). Conclusion Although most of plaque erosions show nearly normal coronary angiogram, modest plaque burden with negative remodeling and an uncommon fibroatheroma might be the nature of plaque erosion. Multimodality intravascular imaging with OCT and VH-IVUS showed fundamentally different pathoanatomic substrates underlying plaque rupture and erosion. PMID:27482258

This prospective cohort study aims to determine if the size of the tendon gap following acute rupture of the Achilles tendon shows an association with the functional outcome following non-operative treatment. All patients presenting within two weeks of an acute unilateral rupture of the Achilles tendon between July 2012 and July 2015 were considered for the study. In total, 38 patients (nine female, 29 male, mean age 52 years; 29 to 78) completed the study. Dynamic ultrasound examination was performed to confirm the diagnosis and measure the gap between ruptured tendon ends. Outcome was assessed using dynamometric testing of plantarflexion and the Achilles tendon Total Rupture score (ATRS) six months after the completion of a rehabilitation programme. Patients with a gap ≥ 10 mm with the ankle in the neutral position had significantly greater peak torque deficit than those with gaps < 10 mm (mean 23.3%; 7% to 52% vs 14.3%; 0% to 47%, p = 0.023). However, there was no difference in ATRS between the two groups (mean score 87.2; 74 to 100 vs 87.4; 68 to 97, p = 0.467). There was no significant correlation between gap size and torque deficit (τ = 0.103), suggesting a non-linear relationship. There was also no significant correlation between ATRS and peak torque deficit (τ = -0.305). This is the first study to identify an association between tendon gap and functional outcome in acute rupture of the Achilles tendon. We have identified 10 mm as a gap size at which deficits in plantarflexion strength become significantly greater, however, the precise relationship between gap size and plantarflexion strength remains unclear. Large, multicentre studies will be needed to clarify this relationship and identify population subgroups in whom deficits in peak torque are reflected in patient-reported outcome measures.

This prospective study was performed to investigate the contribution of early kinesiotherapy, the active exercise and movement of the ankle and knee joints, following a novel surgical technique for reconstruction of the acutely ruptured Achilles tendon and the underlying mechanisms involved. One hundred and seven patients with an acute Achilles tendon rupture received postoperative early kinesiotherapy treatment following the novel ``Pa-bone'' surgical technique. Clinical outcomes were evaluated using the Achilles tendon rupture score, a score for measuring outcomes related to symptoms and physical activity, and bilateral ultrasonographic examination of the Achilles tendon. Range-of-motion recovery equal to the intact side averaged 7~weeks. Double-legged heel rises and sustained single-leg heel rise exercises were possible at an average of 1~week and 60± 2 days, respectively. All patients could perform single-leg heel rise of the injured foot for 60± 23 seconds at an average of 12 weeks. No rerupture was observed. In addition, ultrasonographic examination revealed that the cross-sectional areas of the ruptured tendon were significantly larger than those of the healthy side. Overall reconstruction of the Achilles tendon was obtained for most of the patients. Postoperative early kinesiotherapy treatment following Pa-bone surgical technique resulted in excellent clinical outcomes and contributed to the overall reconstruction of the Achilles tendon.

Susceptibility weighted imaging (SWI) is a very sensitive tool for the detection of microbleeds in traumatic brain injury (TBI). The number and extent of such traumatic microbleeds (TMBs) have been shown to correlate with the severity of the injury and the clinical outcome. However, the acute dynamics of TMBs have not been revealed so far. Since TBI is known to constitute dynamic pathological processes, we hypothesized that TMBs are not constant in their appearance, but may progress acutely after injury. We present here five closed moderate/severe (Glasgow coma scale≤13) TBI patients who underwent SWI very early (average=23.4 h), and once again a week (average=185.8 h) after the injury. The TMBs were mapped at both time points by a conventional radiological approach and their numbers and volumes were measured with manual tracing tools by two observers. TMB counts and extents were compared between time points. TMBs were detected in four patients, three of them displaying an apparent TMB change. In these patients, TMB confluence and apparent growth were detected in the corpus callosum, coronal radiation or subcortical white matter, while unchanged TMBs were also present. These changes caused a decrease in the TMB count associated with an increase in the overall TMB volume over time. We have found a compelling evidence that diffuse axonal injury-related microbleed development is not limited strictly to the moment of injury: the TMBs might expand in the acute phase of TBI. The timing of SWI acquisition may be relevant for optimizing the prognostic utility of this imaging biomarker. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.
Summary Thromboembolic events and major artery occlusion following cerebral aneurysm coiling may lead to serious complications and even death if not treated. The use of an intracranial stent in the setting of subarachnoid hemorrhage (SAH) is risky due to the need for antiplatelet therapy. However in some conditions it could be an effective solution for this major problem. This study describes a revascularization technique using a Solitaire stent for treatment of anterior cerebral artery (ACA) occlusion following coiling of anterior communicating artery (Acom) aneurysms. Three cases of ruptured Acom aneurysms treated during the course of SAH underwent unplanned deployment of an intracranial stent. Complete occlusion of the ACA at the origin of the A2 segment developed during or shortly after coiling. Emergent CT brain scan was done in two cases to exclude rebleeding. Follow-up CT or MRI scans were performed 24 hours after stenting. Technical success was achieved in all cases. Complete revascularization of the Acom was achieved post stent deployment (TIMI grade 3). Time from onset of symptoms to full revascularization in the three cases was 35 minutes, one hour 50 minutes and two hours 40 minutes respectively. No intracranial bleeding occurred in any case following the procedure. No neurological changes occurred in case 1; mild neurological and radiological changes occurred in cases 2 and 3. Deployment of an intracranial stent achieved complete revascularization of the occluded Acom. Its use in a context of SAH is relatively risky but the technique resulted in a significant improvement of symptoms following flow restoration and probably helped prevent symptoms worsening, major disability or even death. A study on a larger patient sample with long-term follow-up will be of value. PMID:23472719

Although simple end-to-end repair of the Achilles tendon is common, many augmented repair protocols have been implemented for acute Achilles tendon rupture. However, whether augmented repair is better than nonaugmented repair of an acute Achilles tendon rupture is still unknown. To conduct a meta-analysis to determine whether augmented surgical repair of an acute Achilles tendon rupture improved subjective patient satisfaction without an increase in rerupture rates. Secondary outcomes assessed included infections, ankle range of motion, calf muscle strength, and minor complications. Meta-analysis. A systematic literature search of peer-reviewed articles was conducted to identify all randomized controlled trials (RCTs) comparing augmented repair and nonaugmented repair for acute Achilles tendon rupture from January 1980 to August 2016 in the electronic databases of PubMed, Web of Science (SCI-E/SSCI/A&HCI), and EMBASE. The keywords (Achilles tendon rupture) AND (surg* OR operat* OR repair* OR augment* OR non-augment* OR end-to-end OR sutur*) were combined, and results were limited to human RCTs and controlled clinical trials published in the English language. Four RCTs involving 169 participants were eligible for inclusion; 83 participants were treated with augmented repair and 86 were treated with nonaugmented repair. Augmented repair led to similar responses when compared with nonaugmented repair for acute Achilles tendon rupture (93% vs 90%, respectively; P = .53). The rerupture rates showed no significant difference for augmented versus nonaugmented repair (7.2% vs 9.3%, respectively; P = .69). No differences in superficial and deep infections occurred in augmented (7 infections) and nonaugmented (8 infections) repair groups during postoperative follow-up ( P = .89). The average incisional infection rate was 8.4% with augmented repair and 9.3% with nonaugmented repair. No significant differences in other complications were found between augmented (7.2%) and

In adults, mallet finger is a traumatic zone I lesion of the extensor tendon with either tendon rupture or bony avulsion at the base of the distal phalanx. High-energy mechanisms of injury generally occur in young men, whereas lower energy mechanisms are observed in elderly women. The mechanism of injury is an axial load applied to a straight digit tip, which is then followed by passive extreme distal interphalangeal joint (DIPJ) hyperextension or hyperflexion. Mallet finger is diagnosed clinically, but an X-ray should always be performed. Tubiana's classification takes into account the size of the bony articular fragment and DIPJ subluxation. We propose to stage subluxated fractures as stage III if the subluxation is reducible with a splint and as stage IV if not. Left untreated, mallet finger becomes chronic and leads to a swan-neck deformity and DIPJ osteoarthritis. The goal of treatment is to restore active DIPJ extension. The results of a six- to eight-week conservative course of treatment with a DIPJ splint in slight hyperextension for tendon lesions or straight for bony avulsions depends on patient compliance. Surgical treatments vary in terms of the approach, the reduction technique, and the means of fixation. The risks involved are stiffness, septic arthritis, and osteoarthritis. Given the lack of consensus regarding indications for treatment, we propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which we treat with extra-articular pinning.

The aim of this study is to introduce a self-designed, minimally invasive technique for repairing an acute Achilles tendon rupture percutaneously. Comparing with the traditional open repair, the new technique provides obvious advantages of minimized operation-related lesions, fewer wound complications as well as a higher healing rate. However, a percutaneous technique without direct vision may be criticized by its insufficient anastomosis of Achilles tendon and may also lead to the lengthening of the Achilles tendon and a reduction in the strength of the gastrocnemius. To address the potential problems, we have improved our technique using a percutaneous Kirschner wire leverage process before suturing, which can effectively recover the length of the Achilles tendon and ensure the broken ends are in tight contact. With this improvement in technique, we have great confidence that it will become the treatment of choice for acute Achilles tendon ruptures. © 2015 Chinese Orthopaedic Association and Wiley Publishing Asia Pty Ltd.

Acute pancreatitis is a rare complication of hydatic disease which occurs following the rupture of a cyst to the intrahepatic bile ducts. Herein, we report a case of a 34-year-old Turkish man, who presented with upper abdominal pain. In laboratory examination, amylase and lipase levels were elevated. Ultrasound examination showed a cystic hypoechoic mass lesion located in the right lobe of the liver with dilated intrahepatic bile ducts, and germinative membranes were detected originating from the ruptured hydatid cyst to the common bile duct. The pancreas was found to be diffusely hypoechoic, consistent with acute pancreatitis. Contrast enhanced CT and MRI were also performed for further evaluation of the primary lesion and its complications.

Isolated traumatic pseudoaneurysms of the basilar artery are extremely rare but often fatal resulting in a mortality rate as high as 50%. A 51-year-old man presented with craniofacial injury after blunt trauma. A brain computed tomography (CT) scan showed thick basal subarachnoid hemorrhage associated with multiple craniofacial fractures, while CT angiography revealed contrast extravasation at the distal basilar artery with pseudoaneurysm formation. After this primary survey, the condition of the patient suddenly deteriorated. Conventional angiography confirmed the contrast extravasation resulted from pseudoaneurysm formation, which was successfully treated with endovascular coil embolization. Decompressive craniectomy and coma therapy with propofol were also performed. However, the patient died on the 7th hospital day because of the poor initial clinical condition. The current case is the first report of acute pseudoaneurysm rupture arising from the basilar artery within the first day after trauma. Our findings suggest the possibility that pseudoaneurysm rupture should be considered if brain CT shows thick traumatic subarachnoid hemorrhage on the basal cistern with a basal skull fracture.
Introduction We report on a patient with an animal bite eye injury, his surgical treatment and proper rabies immunoglobulin administration. Case presentation A 33-year-old Turkey hunter was attacked by a bobcat and his injuries included a ruptured globe with corneal laceration, two iris sphincter tears, and a ruptured anterior capsule with a traumatic cataract. Rabies vaccination was started, primary closure of the corneal laceration, an anterior chamber washout and one week later cataract surgery were performed. Three months postoperatively he achieved an uncorrected visual acuity of 20/50 and a best corrected visual acuity of 20/20. Conclusion Bobcat attacks on humans are very rare and extremely suspicious for rabies infection of the animal. Ophthalmologists need to be aware of the importance of immediate and appropriate post exposure rabies vaccination. Proper rabies immunoglobulin administration in the setting of globe injuries is challenging and we report on the Center for Disease Control and Prevention recommendations for globe injuries.

To determine whether transfusion of mesenchymal stem cells (MSCs) could prevent humoral immune response and autoimmunization against sperms after traumatic testis rupture. Immunomodulatory properties of MSCs have been evaluated by a prospective cohort on 50 adult BALB/c mice. In each interventional arms of study, controlled testis rupture and surgical repair were exerted. In addition to tissue repair, single dose of 5×10(5) MSCs labeled by green fluorescent protein was delivered intravenously to 20 cases (cell therapy group). After euthanizing, seroconversion of antisperm antibody (ASA) was compared between 2 interventional groups as response of humoral immune system. Lung and testis tissues were examined for green fluorescent protein-positive cells to assess whether presence of stem cells is correlated with seroconversion rates. Six cases had been lost during the study. Fourteen of 16 mice in cell therapy control group formed ASA (87.5%) but 6 of 18 mice (33.3%) in cell therapy group were immunized and formed ASA (P=.002). Transplanted cells were traced in lungs of 55% (n=10) of cell therapy group and none were found in trauma site. Small volume of mice blood was our main limitation to trace seroconversion or quantitative measurement of ASA in each case. In this in vivo model of autoimmune infertility, bone marrow-derived MSC transfusion showed immunosuppressive effects on antibody production. Considering immunomodulatory properties of MSCs even in allogeneic settings, novel clinical application should be investigated further. Copyright © 2014 Elsevier Inc. All rights reserved.

A 71-year-old female with rheumatoid arthritis and chronic use of corticosteroids presented to the emergency room with 2 weeks of urinary symptoms, abdominal pain and a mass located in hypo-mesogastrium and both flanks. An X-ray film of the abdomen showed that bowels were displaced by the mass. Laboratory studies showed thrombocytosis (549,000/mm(3)) and leukocytosis (41,800/mm(3)). Several hours after her arrival the patient developed acute abdomen and surgery was indicated. A urinary catheter drained 2100 ml of urine and the abdominal mass was reduced in size but did not disappear. Surgery demonstrated that the urinary bladder covered the fundus and the anterior face of the uterus, where extensive necrosis and a 3-cm perforation were found; 400 ml of foul-smelling pus was drained from the uterine cavity. Due to necrosis, a hysterectomy was performed. The histopathological report indicated necrosis, atrophic cervicitis and endometritis; pus culture developed Escherichia coli and Proteus vulgaris. Despite administration of broad-spectrum antibiotics, the patient developed severe sepsis and died 11 days postoperatively. During a literature review, only one similar case was found. Acute abdomen due to uterine perforation secondary to pyometra and associated with chronic use of corticosteroids is a rare complication.

To evaluate the effectiveness of channel-assisted minimally invasive repair (CAMIR) for acute closed Achilles tendon ruptures. Between January 2011 and June 2012, 30 patients (30 sides) with acute closed Achilles tendon ruptures were treated with CAMIR technique. Among 30 patients, 18 were male and 12 were female with an average age of 30.4 years (range, 22-50 years); the locations were left side in 10 cases and right side in 20 cases. All the causes were sports injury. B-ultrasound was used to confirm the diagnosis, with the average distance from the rupture site to the Achilles tendon insertion of 4.4 cm (range, 2-8 cm). The time from injury to operation was 3 hours to 9 days (median, 4 days). All injuries were repaired by CAMIR technique. The average operation time was 17.0 minutes (range, 10-25 minutes), and the mean incision length was 2.0 cm (range, 1.5-2.5 cm). All the incisions healed by first intention. There was no complication of wound problem, deep vein thrombosis, re-rupture, or sural nerve injury. All cases were followed up 12-24 months with an average of 16 months. At last follow-up, the patients could walk normally with powerful raising heels and restored to normal activity level. MRI imaging suggested the continuity and healing of ruptured tendon. The circumference difference between affected leg and normal leg was less than 1 cm, and the ankle dorsi-extension was 20-30°, plantar flexion was 20-30°. Arner Lindholm score showed that the surgical results were excellent in 28 cases and good in 2 cases, with an excellent and good rate of 100%. CAMIR is a safe and reliable method to repair acute closed Achilles tendon rupture, with many advantages of minimal injury, low re-rupture and infection. Sural nerve injury can be minimized using CAMIR by carefully placing the suture channel with a stab incision and special trocar based on a modified Bunnel suture technique.
Urgent treatment of severe subarachnoid hemorrhage caused by ruptured traumatic aneurysm of the cavernous internal carotid artery using coil embolization followed by superficial temporal artery-middle cerebral artery anastomosis: a case report.

Traumatic aneurysm of the cavernous internal carotid artery (ICA) with extension into the subarachnoid space is associated with increased risk of fatality especially when it is accompanied by severe subarachnoid hemorrhage (SAH). Only cases of patients who survived the acute stage and who were treated in a delayed setting have been reported. There has been no successfully treated case immediately after an injury. We encountered a 48-year-old man who presented with dense SAH immediately after being involved in a motor vehicle accident. Emergent angiography revealed traumatic aneurysm of the left cavernous ICA with extension beyond the superior wall of the cavernous sinus into the subarachnoid space and concomitant direct high-flow carotid cavernous fistula. Detachable platinum coil occlusion of the cavernous ICA followed by superficial temporal artery-middle cerebral artery anastomosis on day 0 and aggressive therapy to SAH, including ventriculocisternal irrigation and drainage, was performed. The patient eventually made a good recovery. Considering the extremely poor prognosis and unstable nature of a ruptured traumatic aneurysm with extensive SAH in the acute stage, definitive and immediate prevention of rebleeding in conjunction with proper revascularization would be warranted, such as in the present case.

The pheochromocytoma is a very rare neoplasm, which originates in 98% of cases in the adrenal medulla; it is often bilateral in familial syndromes. It is more frequent in syndromes like MEN2, von Hippel-Lindau disease, and neuofribromatosis type 1. In this article the Authors report a case of a young woman with a large adrenal pheochromocytoma, that presented by an acute abdomen; the treatment was explorative laparotomy with unilateral adrenalectomy. Therapy of this tumour is founded on surgery, plus chemiotherapy radiotherapy or treatment with 131I-MIBG (iodine-131-metaiodobenzylguanidine in malignant cases (10%). According with the absence of a correlation between pathological findings and clinical behaviour, a long-term follow up is indispensable.

Trauma remains the leading cause of death and morbidity worldwide and bleeding is the primary reason for this mortality. Over the past 11 years there has been a paradigm shift in our understanding of coagulopathy after trauma. Specifically its incidence, biological drivers, clinical sequelae have been elucidated. From this understanding a concurrent change in resuscitation practices has occurred. This manuscript will review the history of resuscitation after injury, the discovery and clinical and biological characterization of acute traumatic coagulopathy and the changes in resuscitation practices aimed at combating coagulopathy and inflammatory perturbation after trauma. Finally it will discuss the ongoing state of the science and suggest topics for continued biological and clinical study. Copyright © 2014. Published by Elsevier Ltd.

The aim of treatment in acute traumatic spinal cord injury is to preserve residual neurologic function, avoid secondary injury, and restore spinal alignment and stability. In this second part of the review, we describe the management of spinal cord injury focusing on issues related to short-term respiratory management, where the preservation of diaphragmatic function is a priority, with prediction of the duration of mechanical ventilation and the need for tracheostomy. Surgical assessment of spinal injuries based on updated criteria is discussed, taking into account that although the type of intervention depends on the surgical team, nowadays treatment should afford early spinal decompression and stabilization. Within a comprehensive strategy in spinal cord injury, it is essential to identify and properly treat patient anxiety and pain associated to spinal cord injury, as well as to prevent and ensure the early diagnosis of complications secondary to spinal cord injury (thromboembolic disease, gastrointestinal and urinary disorders, pressure ulcers).

Optimal treatment of acute Achilles tendon ruptures remains controversial. Positive results using stem-cell-bearing concentrates have been reported with other soft-tissue repairs, but no studies exist on outcomes of bone marrow aspirate concentrate (BMAC) augmentation in primary Achilles tendon repair. We reviewed patients with sport-related Achilles tendon ruptures treated via open repair augmented with BMAC injection from 2009 to 2011. Data on operative complications, strength, range of motion, rerupture, calf circumference and functional improvement through progressive return to sport and the Achilles tendon Total Rupture Score (ATRS) were analysed. A total of 27 patients (28 tendons) treated with open repair and BMAC injection were identified (mean age 38.3 ± 9.6 years). At mean follow-up of 29.7 ± 6.1 months, there were no reruptures. Walking without a boot was at 1.8 ± 0.7 months, participation in light activity was at 3.4 ± 1.8 months and 92% (25 of 27) of patients returned to their sport at 5.9 ± 1.8 months. Mean ATRS at final follow-up was 91 (range 72-100) points. One case of superficial wound dehiscence healed with local wound care. No soft-tissue masses, bone formation or tumors were observed in the operative extremity. Excellent results, including no re-ruptures and early mobilisation, were observed in this small cohort with open Achilles tendon repair augmented by BMAC. No adverse outcomes of biologic treatment were observed with this protocol. The efficacy of BMAC in the operative repair of acute Achilles tendon ruptures warrants further study. IV - Therapeutic.

Little is known regarding acute local and systemic processes following anterior cruciate ligament (ACL) rupture. No study has elucidated whether bone marrow-derived mesenchymal stem cells (MSCs) are mobilized into circulation and recruited to the injured joint. In Part 1, Lewis rats were randomized to noninvasive ACL rupture (Rupture) or non-injured (Control) (n = 6/group). After 72 h, whole blood MSC concentration was assessed using flow cytometry. Synovial fluid and serum were assayed for stromal cell-derived factor (SDF)-1α and cartilage degeneration biomarkers, respectively. In Part 2, 12 additional rats were randomized and intravenously-injected with fluorescently-labeled allogenic MSCs. Cell tracking was performed using longitudinal, in vivo and ex vivo near-infrared (NIR) imaging and histology. Synovium SDF-1α and interleukin (IL)-17A immunostaining was performed. Serum was assayed for SDF-1α and 29 other cytokines. In Part 1, there was a significant increase in MSC concentration and synovial fluid SDF-1α in Rupture. No differences in cartilage biomarkers were observed. In Part 2, Rupture had significantly higher NIR signal at 24, 48, and 72 h, indicating active recruitment of MSCs to the injured joint. Ex vivo cell tracking demonstrated MSC localization in the synovium and myotendinous junction (MTJ) of the quadriceps. Injured synovia exhibited increased synovitis grade and higher degree of IL-17A and SDF-1α immunostaining. ACL rupture induced peripheral blood mobilization of MSCs and migration of intravenously-injected allogenic MSCs to the injured joint, where they localized in the synovium and quadriceps MTJ.

Pseudoaneurysm of the left ventricle is rare and may occur as a result of transmural myocardial infarction. The course of rupture after acute myocardial infarction varies from a catastrophic event, with an acute tear leading to immediate death (acute rupture), or slow and incomplete tear leading to a late rupture (subacute rupture). Incomplete rupture may occur when the thrombus and haematoma together with the pericardium seal the rupture of the left ventricle and may develop into a pseudoaneurysm. Early diagnosis and treatment is essential in this condition. Two-dimensional color Doppler echocardiography is the first-choice method for most patients with suspected left ventricular pseudoaneurysm (LVP) and suggests left ventricular rupture in 85% to 90% of patients. We report the case of an 87-year-old woman presenting with symptoms and findings of myocardial infarction and left ventricular free wall rupture with a pseudoaneurysm formation diagnosed by echocardiography and confirmed on CT, MRI, and NM. She received only intense medical treatment, because she refused surgery with a favorable outcome. After 24-month followup, she is in NYHA functional class II. The survival of this patient is due to the contained pseudoaneurysm by dense pericardial adhesions, related to her previous coronary bypass surgery. PMID:22953155

Introduction: Distal triceps tendon rupture is an uncommon lesion rarely due to a non-traumatic mechanism. In these cases, the majority of patients show predisposing factors for tendon degeneration: underlying medical co-morbidities, previous systemic and locally injected corticosteroids and systemic anabolic steroids. A clear evidence for an etiopathogeneticroleforchronictendonopathy in triceps tendon rupture is sti 11 lacking. Case Report: We report the case of a rare non-traumatic complete rupture of the triceps tendon, at the olecranon insertion, occurring in a healthy male middle-aged non-professional bodybuilder. He presented to our attention with a five days history of weakness, swelling and pain at the left elbow, started after a snapping sound during a single arm triceps extension exercise. He was a healthy sportsman, no smoker and no drinker. He had suffered, in the two months before, of mild bilateral exercise-related elbow discomfort, never limiting his sport and daily activities. The man was treated by an early surgical repair. Histological analysis was conducted on intraoperative samples. The treatment allowed complete remission and return to sport practice without functional deficit. Conclusion: An overload-related chronic tendonopathy was identified as the unique factor with causal role in the determinism of the above described lesion. This case highlights, for the first time in literature, that just a chronic tendonopathy, in absence of any other predisposing condition, can lead to a non-traumatic complete triceps tendon rupture.

We represent the US findings of isolated gallbladder rupture caused by blunt abdominal trauma in a 13-year-old boy. At the initial US examination, although a pericholecystic fluid collection was observed, the mildly collapsed gallbladder was regarded as a contracted gallbladder. Even though the patient was haemodynamically stable, repeat US examination after 24 h revealed gallbladder perforation. In haemodynamically stable trauma patients repeated US examinations can be useful and are strongly recommended.

Acute complete Achilles tendon ruptures are commonly missed injuries. We propose the Realtime Achilles Ultrasound Thompson (RAUT) test, a Thompson test under ultrasound visualization, to aid in the diagnosis of these injuries. We hypothesized that RAUT testing would provide improved diagnostic characteristics compared with static ultrasound. Twenty-two consecutive patients with operatively confirmed acute Achilles tendon ruptures were prospectively evaluated with RAUT testing and static ultrasonography. RAUT video recordings and static ultrasound images from both ruptured and uninjured sides were randomized and graded by a group of novice reviewers and a group of expert attendings. From these observations, sensitivity, specificity, positive predictive value, and negative predictive value for RAUT and static ultrasound were calculated. In addition, κ interobserver coefficients were computed. Forty-seven novice reviewers and 11 foot and ankle attendings made a total of 4136 and 528 observations, respectively. For static ultrasound, sensitivity and specificity were 76.8% and 74.8% for the novice reviewers and 79.6% and 86.4% for the attendings, respectively. For RAUT testing, sensitivity and specificity were 87.2% and 81.1% for the novice group and 86.4% and 91.7% for the attending group, respectively. The κ coefficient was 0.62 and 0.27 for novice and attending RAUT reviewers, indicating substantial and fair agreement, respectively, but only 0.46 and 0.12 for static ultrasonography, representing moderate and slight agreement, respectively. RAUT testing was a sensitive and specific test, providing a cost-effective adjunct to the clinical examination when diagnosing acute Achilles tendon ruptures. This test can be used by surgeons with minimal training in ultrasonography. Level II, diagnostic study.

A 54-year-old man was admitted to our hospital with complaint of sudden headache. The patient had suffered two episodes of transient headache before admission. Computed tomography (CT) revealed acute subdural hematoma (ASDH) on the right side of the cerebral convexity with bilateral extension along the tentorium cerebelli without signs of subarachnoid hemorrhage (SAH) or intracerebral hemorrhage (ICH). Three-dimensional CT angiography and conventional cerebral angiography revealed a left A1-A2 junction aneurysm. Neck clipping of the aneurysm was performed. The aneurysm extended inferiorly, with the dome embedded in the chiasmatic cistern and tightly adhered to the arachnoid membrane. There was no evidence of hematoma in the subarachnoid space. The patient was discharged without neurological deficit. Ruptured aneurysms resulting in ASDH without SAH or ICH are very rare. Radiological investigation such as three-dimensional CT angiography should be performed to find the causative aneurysm in a patient with ASDH with a history of repeated headaches and without traumatic signs or episodes, and the appropriate treatment should be planned with expediency.

To investigate the value of high frequency ultrasonography in the diagnosis of zone 2 flexor tendon injuries. Ninety-two patients (49 males and 43 females, mean age 32.6 ± 11.2 years) with zone 2 flexor tendon injuries in one or more digits were randomly divided into a study (n = 46, 95 digits) and a control group (n = 46, 90 digits). In the study group, preoperative ultrasound was performed and surgical repair was conducted based on ultrasonographic findings. Diagnosis and surgical repair of the control group was based on history of trauma and physical examination. Types of ruptures (complete or partial) and the location of the distal end of the ruptured tendon diagnosed by preoperative ultrasonography were consistent with surgical findings in all cases (95/95, 100%) of the study group, whereas the concordance rate between clinically diagnosed ruptures and surgical findings was only 34.4% (31/90) in the control group (p = 0.02). Preoperative high frequency ultrasound examination yielded excellent diagnostic accuracy for zone 2 flexor tendon injuries. Copyright © 2012 S. Karger AG, Basel.

The term 'acute myelopathies'--referred to a spinal cord dysfunction--represent a heterogeneous group of disorders with distinct etiologies, clinical and radiologic features, and prognoses. The objective of this review is to discuss the non-traumatic acute myelopathies. Acute myelopathy can be due to several causes as infective agents or inflammatory processes, such as in acute myelitis, compressive lesions, vascular lesions, etc. The clinical presentation is often dramatic with tetraparesis or paraparesis, sensory disturbances and bladder and/or bowel dysfunction. History and physical examination are used to localize the lesion to the root or specific level of the cord, which can guide imaging. Different syndromes are recognized: complete transverse lesion, central grey matter syndrome, anterior horn syndrome, anterior spinal artery syndrome, etc). The first priority is to rule out a compressive lesion. If a myelopathy is suspected, a gadolinium-enhanced MRI of the spinal cord should be obtained as soon as possible. If there is no structural lesion such as epidural blood or a spinal mass, then the presence or absence of spinal cord inflammation should be documented with a lumbar puncture. The absence of pleocytosis would lead to consideration of non inflammatory causes of myelopathy such as arteriovenous malformations, fibrocartilaginous embolism, or possibly early inflammatory myelopathy. In the presence of an inflammatory process (defined by gadolinium enhancement, cerebrospinal fluid pleocytosis, or elevated cerebrospinal fluid immunoglobulin index), one should determine whether there is an inflammatory or an infectious cause. Different virus, bacterias, parasites and fungi have to be considered as autoimmune and inflammatory diseases that involve the central nervous system.

Acute subdural hematoma (ASDH) is mostly caused by head trauma, but intrinsic causes also exist such as aneurysm rupture. We describe here a case involving a man in his 70s who was found lying on the bedroom floor by his family. CT performed at the hospital showed ASDH and a forensic autopsy was requested. Postmortem cerebral angiography showed dilatation of the bifurcation of the middle cerebral artery, which coincided with the dilated part of the Sylvian fissure. Extravasation of contrast medium into the subdural hematoma from this site was suggestive of a ruptured aneurysm. Autopsy revealed a fleshy hematoma (total weight 110 g) in the right subdural space and findings of brain herniation. As indicated on angiography, a ruptured saccular aneurysm was confirmed at the bifurcation of the middle cerebral artery. Obvious injuries to the head or face could not be detected on either external or internal examination, and intrinsic ASDH due to a ruptured middle cerebral artery aneurysm was determined as the cause of death. One of the key points of forensic diagnosis is the strict differentiation between intrinsic and extrinsic onset for conditions leading to death. Although most subdural hematomas (SDH) are caused by extrinsic factors, forensic pathologists should consider the possibility of intrinsic SDH. In addition, postmortem angiography can be useful for identifying vascular lesions in such cases.

We reviewed the outcomes of the Achillon minimally invasive suture system and an early semi-functional rehabilitation program for the treatment of acute Achilles tendon ruptures. From December 2006 to April 2008, 18 consecutive patients with acute Achilles tendon ruptures were retrospectively reviewed with an average follow-up of 22 months. Clinical data were assessed with the patient satisfaction and the AOFAS hindfoot score. Biomechanical gait parameters were obtained using the NedAMH/IBV dynamometric platform. At last follow-up the AOFAS score was 98 (range, 89-100) and correlated well with kinetic gait analysis. All patients regained normal range of motion and were able to resume their previous activities after six months, with a high rate of satisfaction. Three patients had scar adhesions. There were no cases of recurrent rupture or nerve injury. The Achillon device allows semi-functional rehabilitation and provides satisfactory results with a low rate of complication.

Undescended testicle is the most common congenital anomaly among males. Testicular tumor develops in 3–5% of the boys with a complaint of undescended testicle. The clinical presentation of malignant intra-abdominal testicular tumors ranges from asymptomatic cases to acute abdomen. In this study, we present a child with testicular tumor rupture which is observed very rarely. A 16-year-old boy presented 24 hours after the sudden onset of right lower quadrant pain, nausea, vomiting and fever. On physical examination, extensive tenderness in the abdomen and abdominal guarding were found. The right testicle was not palpable. The serum white blood cell count was elevated. Ultrasonography and abdominal computerized tomography scan demonstrated a perforated, hyperdense mass with free fluid in the abdomen. The preoperative alpha fetoprotein level was found to be increased. We performed surgery with laparoscopy and a perforated right intraabdominal testicle was found in the right iliac fossa. The mass was excised. Histopathological examination revealed a yolk sac tumor. Ruptured nonpalpable testicular tumors are very rare. To our knowledge, this is the first adolescent case reported so far. Testicular tumor rupture should be considered in patients with nonpalpable testicle and acute abdomen. Laparoscopy may be performed in differential diagnosis and treatment of these patients. PMID:27738401

Achilles tendon rupture is a common injury, especially in those who are physically active. Although open surgery is a widely used option for the treatment of acute Achilles tendon rupture, the optimal treatment is still disputed. In our study, 59 patients with unilateral, closed, acute rupture of the Achilles tendon were treated by open surgery using an allograft weave to augment the repair. All the surgeries were performed within 1 to 4 days after injury. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score was recorded as 91.20 (range 88 to 95), 95.34 (range 92 to 98), and 98.27 (range 97 to 99) at the 3-, 6-, and 12-month follow-up visit, respectively. At the final follow-up visit, the mean difference between the mid-calf circumference of the injured and uninjured legs was 0.19 (range -0.03 to 1.50) cm (p = .43). At the final follow-up visit, the mean difference between the vertical distances from the plantar surface of the heel to the ground for the injured and uninjured lower extremities was 0.44 (range -0.03 to 0.5) cm (p = .17). Augmented repair using the allograft tendon weaving technique provided satisfactory tendon strength and functional outcomes and a timely return to the patients' activities.

Extracorporeal membrane oxygenation (ECMO) has been successfully used for the treatment of patients with respiratory failure due to severe infections. Though rare, parasites can also cause severe pulmonary disease. Tapeworms of the genus Echinococcus give rise to the development of cystic structures in the liver, lungs and other organs. Acute cyst rupture leads to potentially life-threatening infection, and affected patients may deteriorate rapidly. We describe the case of a young woman from Bulgaria who was admitted to hospital with severe dyspnoea, progressive chest pain and haemoptysis. Computed tomography of the chest was pathognomonic of cystic echinococcosis with acute cyst rupture. Following deterioration on mechanical ventilation, she was cannulated for veno-venous ECMO. The patient's condition improved considerably, and she could successfully be weaned from ECMO and mechanical ventilation. Following lobectomy of the affected left lower lobe, she was discharged home in good condition. This is the first report on the successful use of ECMO as salvage treatment for a severe manifestation of a helminthic disease. Due to recent migration to Western Europe, the number of patients presenting with respiratory failure due to pulmonary echinococcosis with cyst rupture is likely to increase. Copyright © 2017.

High rates of adverse outcomes have been reported following blast-related concussive traumatic brain injury in US military personnel, but the extent to which such adverse outcomes can be predicted acutely after injury is unknown. We performed a prospective, observational study of US military personnel with blast-related concussive traumatic brain injury (n = 38) and controls (n = 34) enrolled between March and September 2012. Importantly all subjects returned to duty and did not require evacuation. Subjects were evaluated acutely 0-7 days after injury at two sites in Afghanistan and again 6-12 months later in the United States. Acute assessments revealed heightened post-concussive, post-traumatic stress, and depressive symptoms along with worse cognitive performance in subjects with traumatic brain injury. At 6-12 months follow-up, 63% of subjects with traumatic brain injury and 20% of controls had moderate overall disability. Subjects with traumatic brain injury showed more severe neurobehavioural, post-traumatic stress and depression symptoms along with more frequent cognitive performance deficits and more substantial headache impairment than control subjects. Logistic regression modelling using only acute measures identified that a diagnosis of traumatic brain injury, older age, and more severe post-traumatic stress symptoms provided a good prediction of later adverse global outcomes (area under the receiver-operating characteristic curve = 0.84). Thus, US military personnel with concussive blast-related traumatic brain injury in Afghanistan who returned to duty still fared quite poorly on many clinical outcome measures 6-12 months after injury. Poor global outcome seems to be largely driven by psychological health measures, age, and traumatic brain injury status. The effects of early interventions and longer term implications of these findings are unknown. © The Author (2015). Published by Oxford University Press on behalf of the Guarantors of Brain. All

False aneurysm of the thoracic aorta unrelated to trauma, or to previous aortic or cardiac surgery, is extremely rare. We encountered a case of ascending aortic false aneurysm formation associated with ruptured acute type A aortic dissection. The false aneurysm, which was contained by thin connective tissue surrounding the aortic wall, was located beside the false lumen of the dissected ascending aorta, expanding toward the transverse sinus. We immediately decided to perform an emergency operation. We noted the large entry site at the anterior wall of the dissected ascending aorta after resection of the flap. We identified the false aneurysm arising from a small tear of the false lumen. Graft replacement of the ascending aorta using a tube graft was performed. The postoperative course was satisfactory. This pathology was believed to be not only a consequence of hemostasis, but also a process of re-rupture of the dissected aorta.

Abstract Hormonal dysfunction is a known consequence of moderate and severe traumatic brain injury (TBI). In this study we determined the incidence, time course, and clinical correlates of acute post-TBI gonadotroph and somatotroph dysfunction. Patients had daily measurement of serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, estradiol, growth hormone, and insulin-like growth factor-1 (IGF-1) for up to 10 days post-injury. Values below the fifth percentile of a healthy cohort were considered abnormal, as were non-measurable growth hormone (GH) values. Outcome measures were frequency and time course of hormonal suppression, injury characteristics, and Glasgow Outcome Scale (GOS) score. The cohort consisted of 101 patients (82% males; mean age 35 years; Glasgow Coma Scale [GCS] score ≤8 in 87%). In men, 100% had at least one low testosterone value, and 93% of all values were low; in premenopausal women, 43% had at least one low estradiol value, and 39% of all values were low. Non-measurable GH levels occurred in 38% of patients, while low IGF-1 levels were observed in 77% of patients, but tended to normalize within 10 days. Multivariate analysis revealed associations of younger age with low FSH and low IGF-1, acute anemia with low IGF-1, and older age and higher body mass index (BMI) with low GH. Hormonal suppression was not predictive of GOS score. These results indicate that within 10 days of complicated mild, moderate, and severe TBI, testosterone suppression occurs in all men and estrogen suppression occurs in over 40% of women. Transient somatotroph suppression occurs in over 75% of patients. Although this acute neuroendocrine dysfunction may not be TBI-specific, low gonadal steroids, IGF-1, and GH may be important given their putative neuroprotective functions. PMID:20214417

We present the case of a 63-year-old woman with a remote history of supraventricular tachycardia and hyperlipidemia, who presented with recurrent episodes of acute-onset chest pain. An electrocardiogram showed no evidence of acute coronary syndrome. A chest radiograph revealed a prominent right-sided heart border. A suspected congenital pericardial cyst was identified on a computed tomographic chest scan, and stranding was noted around the cyst. The patient was treated with nonsteroidal anti-inflammatory drugs, and the pain initially abated. Another flare-up was treated similarly. Cardiac magnetic resonance imaging was then performed after symptoms had resolved, and no evidence of the cyst was seen. The suspected cause of the patient's chest pain was acute inflammation of a congenital pericardial cyst with subsequent rupture and resolution of symptoms. PMID:28100978

Acute compartment syndrome is a serious emergency that warrants urgent decompression, and tennis leg (i.e., rupture of the medial head of the gastrocnemius) is a known clinical condition that is usually treated symptomatically, with good results overall. In rare cases, acute compartment syndrome is associated with tennis leg after severe direct muscle trauma or severe exercise in athletes or physically active individuals. We present an unusual case of acute compartment syndrome secondary to tennis leg after the patient, a nonathlete, had disembarked from a truck without any trauma. Clinicians should have a high index of suspicion for atraumatic compartment syndrome, and timely surgical fasciotomy must be undertaken to avoid complications resulting from delayed diagnosis and treatment.

The present report describes a case of splenic rupture due to dengue, a rare complication of dengue that should be considered in any patient with suspected dengue disease who started with left upper quadrant abdominal pain and hypotension. The pathophysiology of this entity is not yet well elucidated, but one of the theories present in the literature is that it is due to a depletion of coagulation factors and platelets leading to intra-splenic hemorrhage and rupture. The RT-PCR technique detected serotype 1 and histopathological studies of the spleen revealed significant atrophy of lymphoid follicles and extensive hemorrhage areas. Besides histopathological observations, virus replication was investigated by detection of dengue antigens, especially the non-structural 3 protein (NS3) in endothelial cells and splenic macrophages. This important complication has serious clinical repercussions and high mortality, due to the diagnostic difficulty and many factors that usually confuse or delay its diagnosis. Therefore, it is of the utmost importance to recognize their manifestations and their management to try to best minimize their consequences and mortality.
Background We report a case of delayed endovascular correction of graft collapse occurred after emergent Thoracic Endovascular Aortic Repair (TEVAR) for traumatic aortic isthmus rupture. Case presentation In 7th post-operative day after emergent TEVAR for traumatic aortic isthmus rupture (Gore TAG® 28-150), a partial collapse of the endoprosthesis at the descending tract occurred, with no signs of visceral ischemia. Considering patient's clinical conditions, the graft collapse wasn't treated at that time. When general conditions allowed reintervention, the patient refused any new treatment, so he was discharged. Four months later the patient complainted for severe gluteal and sural claudication, erectile disfunction and abdominal angina; endovascular correction was performed. At 18 months the graft was still patent. Discussion and Conclusion Graft collapse after TEVAR is a rare event, which should be detected and treated as soon as possible. Delayed correction of this complication can be lethal due to the risk of visceral ischemia and limbs loss. PMID:21609433
differential diagnosis of acute abdomen in endemic areas. The operative procedures, either radical or conservative, should be based on the patient’s condition, the regional characteristics, and the surgeon’s experience. The morbidity and mortality rates of surgical interventions for ruptured hydatid cysts are higher than the rates for elective uncomplicated cases. PMID:23885766

The purpose of this study was to report the experience of dynamic intraligamentary stabilisation (DIS) using the Ligamys device for the treatment of acute ruptures of the anterior cruciate ligament (ACL). Between March 2011 and April 2012, 50 patients (34 men and 16 women) with an acute rupture of the ACL underwent primary repair using this device. The mean age of the patients was 30 years (18 to 50). Patients were evaluated for laxity, stability, range of movement (ROM), Tegner, Lysholm, International Knee Documentation Committee (IKDC) and visual analogue scale (VAS) scores over a follow-up period of two years. At final follow-up, anteroposterior translation differed from the normal knee by a mean of 0.96 mm (-2 mm to 6 mm). Median (interquartile range) IKDC, Tegner, Lysholm and VAS scores were 98 (95 to 100), 6 (5 to 7), 100 (98 to 100) and 10 (9 to 10), respectively. Pre-injury Tegner activity levels were reached one year post-operatively. A total of nine patients (18%) required a secondary intervention; five developed instability, of whom four underwent secondary hamstring reconstructive surgery, and five required arthroscopic treatment for intra-articular impingement due to scar tissue which caused a fixed flexion deformity. In addition, 30 patients (60%) required removal of the tibial screw. While there was a high rate of secondary interventions, 45 patients (90%) retained their repaired ACL two years post-operatively, with good clinical scores and stability of the knee. Dynamic intraligamentary stabilisation presents a promising treatment option for acute ACL ruptures, eliminating the need for ACL reconstruction.

Diaphragmatic injury following blunt thoracoabdominal trauma is rare and is usually associated with key radiological features like dependent viscera sign, collar sign, diaphragmatic thickening and defects. It may also be associated with secondary signs like intrathoracic herniation of abdominal viscera. Diaphragmatic crura, which are attached to the upper lumbar vertebra represent prominently thickened folds along the posterior diaphragm, are usually inconspicuous on routine Computed Tomography (CT) scans. We present a case of a young patient who sustained a motor vehicle accident and developed difficulty in breathing. CT scan of the patient revealed bilateral crural hematomas, with splenic and renal lacerations and no other sign of diaphragmatic injury. The patient was operated and blunt diaphragmatic rupture was confirmed at surgery. PMID:25337318

Lateral left ventricular wall rupture (LVWR) is a rare complication following acute myocardial infarction (AMI) less than 1%. After cardiogenic shock, LVWR constitutes the most common cause of in-hospital death in AMI patients. Around 40% of all LVWR occurred during the first 24 hours and 85% within the first week. In the present case, 76 hours following the intervention, LVWR was observed likely due to a small infarction at the lateral left ventricular wall possibly due to the marginal lesion. Our patient refused surgery and was followed clinically. Eighteen months later, real time three-dimensional echocardiography showed a pseudoaneurysm.

Acute subdural hematoma (ASDH) is a type of intracranial haemorrhage following head impact, with high mortality rates. Bridging vein (BV) rupture is a major cause of ASDH, which is why a biofidelic representation of BVs in finite element (FE) head models is essential for the successful prediction of ASDH. We investigated the mechanical behavior of BVs in the KTH FE head model. First, a sensitivity study quantified the effect of loading conditions and mechanical properties on BV strain. It was found that the peak rotational velocity and acceleration and pulse duration have a pronounced effect on the BV strains. Both Young's modulus and diameter are also negatively correlated with the BV strains. A normalized multiple linear regression model using Young's modulus, outer diameter and peak rotational velocity to predict the BV strain yields an adjusted [Formula: see text]-value of 0.81. Secondly, cadaver head impact experiments were simulated with varying sets of mechanical properties, upon which the amount of successful BV rupture predictions was evaluated. The success rate fluctuated between 67 and 75%. To further increase the predictive capability of FE head models w.r.t. BV rupture, future work should be directed towards improvement of the BV representation, both geometrically and mechanically.

Spontaneously ruptured hepatocellular carcinoma (HCC) with hemoperitoneum has a poor prognosis, especially in cases of cirrhosis. Patients usually present to emergency rooms (ERs) with acute abdomen. The aim of the present study was to determine the factors affecting mortality and to compare the prognosis of conservative treatment, transcatheter arterial embolization (TAE), or hepatectomy in these situations. Fifty-four patients with spontaneously ruptured HCC diagnosed between January 2004 and August 2010 were enrolled in this retrospective review of clinical data. Grouping by survival or mortality, univariate and multivariate analyses of factors affecting 30-day mortality, and long-term survival were conducted. The outcomes of the various treatments were analyzed. After primary fluid resuscitation in the ER, 6 of 54 patients underwent conservative treatment. Emergency hepatectomy was performed on 19 patients; TAE was used for 29 patients, 18 of whom received staged hepatectomy thereafter. Poor liver function, prolonged international normalized ratio (INR), and conservative treatment were associated with increased 30-day mortality. Logistic regression analysis of cumulative survival revealed that INR ≥ 1.4, multiple intrahepatic HCC, and conservative treatment were related to poorer long-term survival. The patients who received hepatectomy, either immediate or staged after TAE, had higher survival rates of 85.2 % at 30 days and 62.2 % at 1 year. The treatment of ruptured HCC should be tailored to the individual case. Prolonged survival is possible in patients with preserved liver function through curative liver resection. Emergency physicians, radiologists, and surgeons play essential roles in managing these patients.

This minireview describes 6 previously reported patients with left ventricular free wall rupture and/or aneurysm complicating acute myocardial infarction (AMI) in patients with aortic stenosis. The findings suggest that left ventricular rupture and/or aneurysm is more frequent in patients with AMI associated with aortic stenosis than in patients with AMI unassociated with aortic stenosis, presumably because of retained elevation of the left ventricular peak systolic pressure after the appearance of the AMI.

Chronic tendinopathy is characterized by pain in the tendon, generally at the start and completion of exercise. However, tendinosis may lead to decreased blood flow, increased stiffness of the tendon and reduced tensile strength, and predispose to rupture. Operative treatment is indicated to restore the function of the Achilles tendon and alleviate the prerupture heel cord pain. A case of acute Achilles tendon rupture with extensive tendinosis that was successfully treated with minimally invasive flexor hallucis longus transfer is reported.

The Achilles tendon Total Rupture Score was developed by a research group in 2007 in response to the need for a patient reported outcome measure for this patient population. Beyond this original development paper, no further validation studies have been published.Consequently the purpose of this study was to evaluate internal consistency, convergent validity and responsiveness of this newly developed patient reported outcome measure within patients who have sustained an isolated acute Achilles tendon rupture. Sixty-four eligible patients with an acute rupture of their Achilles tendon completed the Achilles tendon Total Rupture Score alongside two further patient reported outcome measures (Disability Rating Index and EQ 5D). These were completed at baseline, six weeks, three months, six months and nine months post injury. The Achilles tendon Total Rupture Score was evaluated for internal consistency, using Cronbach's alpha, convergent validity, through correlation analysis and responsiveness, by analysing floor and ceiling effects and calculating its relative efficiency in comparison to the Disability Rating Index and EQ 5D scores. The Achilles tendon Total Rupture Score demonstrated high internal consistency (Cronbachs alpha > 0.8) and correlated significantly (p < 0.001) with the Disability Rating Index at five time points (pre-injury, six weeks, three, six and nine months) with correlation coefficients between -0.5 and -0.9. However, the confidence intervals were wide. Furthermore, the ability of the new score to detect clinically important changes over time (responsiveness) was shown to be greater than the Disability Rating Index and EQ 5D. A universally accepted outcome measure is imperative to allow comparisons to be made across practice. This is the first study to evaluate aspects of validity of this newly developed outcome measure, outside of the developing centre. The ATRS demonstrated high internal consistency and responsiveness, with limited convergent

The purpose of this study was to carefully examine the effects of a complicated vs uncomplicated mild traumatic brain injury (MTBI) on acute neuropsychological outcome. Participants were derived from an archival trauma database. This is a retrospective matched groups design. All patients were seen through a Head Injury Trauma Service clinical pathway. To be included, all patients must have undergone a day-of-injury CT scan and completed a small battery of neuropsychological tests within 2 weeks of injury. Patients were sorted into two groups on the basis of having a normal or abnormal CT scan. Patients were then carefully matched on age, education, gender and mode of injury (e.g. car accident, fall or assault). The final sample consisted of 100 patients, with 50 in each group. The patients with complicated MTBIs performed significantly more poorly on some of the neuropsychological tests. However, the effect sizes were small or medium and the two groups could not be differentiated using logistic regression analysis. The reasons why people recover slowly or fail to recover fully from MTBIs remain poorly understood. Visible structural brain damage carries increased risk for slow and incomplete recovery, but certainly does not provide an explanation for good or poor outcome in the majority of patients.

There are nearly 1.8 million annual emergency room visits and over 289,000 annual hospitalizations related to traumatic brain injury (TBI). The goal of this review article is to highlight pharmacotherapies that we often use in the clinic that have been shown to benefit various sequelae of TBI. We have decided to focus on sequelae that we commonly encounter in our practice in the post-acute phase after a TBI. These symptoms are hyper-arousal, agitation, hypo-arousal, inattention, slow processing speed, memory impairment, sleep disturbance, depression, headaches, spasticity, and paroxysmal sympathetic hyperactivity. In this review article, the current literature for the pharmacological management of these symptoms are mentioned, including medications that have not had success and some ongoing trials. It is clear that the pharmacological management specific to those with TBI is often based on small studies and that often treatment is based on assumptions of how similar conditions are managed when not relating to TBI. As the body of the literature expands and targeted treatments start to emerge for TBI, the function of pharmacological management will need to be further defined.

The applications of CT examination in the diagnosis of the acute Achilles tendon rupture (AATR) were investigated. A total of 36 patients with suspected acute Achilles tendon rupture were tested using physical examination, ultrasound, and 3DCT scanning, respectively. Then, surgery was performed for the patients who showed positive result in at least two of the three tests for AATR. 3DVR, MPR, and the other CT scan image processing and diagnosis were conducted in PACS (picture archiving and communication system). PACS was also used to measure the length of distal broken ends of the Achilles tendon (AT) to tendon calcaneal insertion. Our study indicated that CT has the highest accuracy in diagnosis of acute Achilles tendon complete rupture. The length measurement is matched between PACS and those actually measured in operation. CT not only demonstrates more details directly in three dimensions especially with the rupture involved calcaneal insertion flap but also locates the rupture region for percutaneous suture by measuring the length of distal stump in PACS without the effect of the position of ankle. The accuracy of CT diagnosis for Achilles tendon partial rupture is yet to be studied.

The purpose of this prospective randomized controlled study was to evaluate the long-term results after an acute Achilles tendon rupture in patients treated surgically or non-surgically. The focus was to evaluate whether any improvements occurred between the one and 2-year evaluation. Eighty-one patients (67 men, 14 women) with a mean (SD) age of 42 (9.1) were included in this study. Forty-two patients were treated surgically, and 39 treated non-surgically otherwise the treatment was identical for the two groups. All patients were evaluated using the Achilles tendon Total Rupture Score (ATRS), the Physical Activity Scale (PAS) and validated functional tests one and 2 years after injury. There were significant functional deficits on the injured side compared with the contralateral side 2 years after Achilles tendon rupture, regardless of treatment. Only minor improvements, even though statistically significant, occurred between the 1- and 2-year evaluations. The physical activity level remained significantly reduced as compared with prior to injury, but the ATRS mean was relatively high in both groups (89 and 90). This long-term follow-up indicates that the majority of patients with an Achilles tendon rupture have not fully recovered (in regards to symptoms, physical activity level and function) 2 years after injury regardless of surgical or non-surgical treatment. Furthermore, only minor improvements occur between the 1- and 2-year evaluations. This indicates that to enhance the final outcome the focus should be on improvements in treatment within the first year. The patients appear to have adjusted to their impairments since the patient-reported outcome is relatively high in spite of functional deficits and lower activity level compared with pre-injury. Prospective randomized study, Level I.

Summary Endovascular treatment has assumed a role of first choice in the management of ruptured intracranial aneurysms. We describe the clinical and morphological data after the treatment of 258 ruptured intracranial aneurysms in 241 patients, in order to evaluate the safety and the efficacy of the endovascular treatment. Two hundred and forty-one patients with saccular ruptured aneurysms were treated at our institution between 2000 and 2005. After the endovascular treatment a clinical and angiographic follow-up was conducted. The clinical follow-up was carried out with a medical examination and telephonic interviews and mRS was used for evaluation. Two hundred and forty-nine acutely ruptured aneurysms were successfully treated and immediately after the endovascular procedure 81.9% of the aneurysms resulted completely occluded, 12.1% had a residual neck and 6% revealed a residual sac. The evolution of each grade was evaluated at six months and two years. During the follow-up we observed five early and one late re-bleedings. Twenty-four patients underwent a second procedure. After the discharge and up to ten years 73.1% of patients had a good clinical outcome (mRS0-1), 8.9% died and the remainder showed moderate-severe disability (mRS2-3). The long-term stability of the anatomical result is a critical issue of this approach because eventual re-bleedings may occur even after several months or years. A careful clinical and radiological follow-up for up to two years after the embolization may prevent recurrences but may not be sufficient. PMID:22440595

With the advancement of the Coronary Care Units in the past three decades, there had been an important reduction in mortality secondary to arrhythmias in acute myocardial infarction (AMI): been now days, cardiogenic shock and cardiac rupture the first and second causes of in-hospital death in these patients. The purpose of this report is to know the anatomoclinical characteristics in our hospital of cardiac rupture and to look for risk factors that may be considered to diagnose at the precise time this complication that might cause sudden death secondary to hemodynamic and electromechanical changes. From 300 postmortem cases with AMI proved clinical, and by anatomopathological studies, 20 cases with cardiac rupture were obtained, among which: 11 (55%) were males with an average age of 61.7 years and 9 (45%) females, with an average age of 60 years. The following coronary risk factors were detected: systemic hypertension in 15 (75%) cases; cigarette smoking in 13 (65%) cases and diabetes mellitus in 11 (55%) cases. Long lasting or recurrent history of chest pain previous to death was present in 14 (70%) cases. Conduction disturbances were detected in 13 (65%) cases; among them, 7 (35%) had third degree heart block in whom permanent pacemaker was inserted; 4 (20%) had CRBBB and 2 (10%) ASB. The average heart weight was 478 gr. in males and 434 gr. in females. Evidence of an old MI was present in 7 (35%) cases. All patients had transmural MI. Free cardiac wall rupture was seen in 14 (70%) cases and from the ventricular septum, 6 (30%) cases. Hemopericardium was present in all cases (100%) with an average amount of 425 ml of blood. Pericarditis in 3 (15%). The average time of evolution since the beginning of the AMI until death were 4 days and the main causes of death were cardiogenic shock in 17 (85%) and congestive heart failure in 3 (15%).

Most of the retrospective studies have demonstrated that traumatic brain injury mediated hypopituitarism could be more frequent than previously known. Therefore, this study has prospectively investigated pituitary function and their correlation with severity, pressure effect and Glasgow Outcome Scale in the acute phase of moderate-to-severe traumatic brain injury. One hundred consecutive moderate-to-severe traumatic brain injury patients from August 2012 to November 2013 formed the study group. Apart from clinical assessment, non-contrast computed tomography of the head was performed on all patients on admission. The hormonal analysis (fT3, fT4, TSH, GH, Cortisol, Prolactin) was performed within 24 hours of traumatic brain injury and was repeated on the 7th day amongst the patients who survived. Growth hormone was the most common hormone to decrease. Cortisol was the most common hormone to increase. Risk of pituitary insufficiency was increased in patients with severe traumatic brain injury, patients with increased intracranial pressure and who had low Glasgow Outcome Scale. Neuroendocrine dysfunction occurs often in the acute phase of moderate-to-severe traumatic brain injury, more commonly in patients with severe traumatic brain injury, patients with pressure effects and low Glasgow Outcome Scale. Hormonal analysis should be considered in patients with moderate-to-severe traumatic brain injury, so that appropriate hormonal replacement can be done to optimize the clinical outcome.

There is a lack of consensus regarding the best option for the treatment of acute Achilles tendon rupture. Treatment can be broadly classified as operative (open or percutaneous) or nonoperative (casting or functional bracing). Postoperative splinting can be performed with a rigid cast (proximal or distal to the knee) or a more mobile functional brace. The aim of this meta-analysis was to identify and summarize the evidence from randomized, controlled trials on the effectiveness of different interventions for the treatment of acute Achilles tendon ruptures. We searched multiple databases (including EMBASE, CINAHL, and MEDLINE) as well as reference lists of articles and contacted authors. Keywords included Achilles tendon, rupture, and tendon injuries. Three reviewers extracted data and independently assessed trial quality with use of a ten-item scale. Twelve trials involving 800 patients were included. There was a variable level of methodological rigor and reporting of outcomes. Open operative treatment was associated with a lower risk of rerupture compared with nonoperative treatment (relative risk, 0.27; 95% confidence interval, 0.11 to 0.64). However, it was associated with a higher risk of other complications, including infection, adhesions, and disturbed skin sensibility (relative risk, 10.60; 95% confidence interval, 4.82 to 23.28). Percutaneous repair was associated with a lower complication rate compared with open operative repair (relative risk, 2.84; 95% confidence interval, 1.06 to 7.62). Patients who had been managed with a functional brace postoperatively (allowing for early mobilization) had a lower complication rate compared with those who had been managed with a cast (relative risk, 1.88; 95% confidence interval, 1.27 to 2.76). Because of the small number of patients involved, no definitive conclusions could be made regarding different nonoperative treatment regimens. Open operative treatment of acute Achilles tendon ruptures significantly reduces

A 49-year-old male athlete sustained a complete rupture of the pectoralis major muscle while bench pressing. The inferior and the superior border of the clavicular lamina and the sternal lamina were fixed with mattress sutures. After that transosseous reinsertion via drill holes (no suture anchors). The lateral rim of both tendons was fixed with Mason-Allen sutures. Final adaption of the distal tendon stump above the reinserted tendon (doubling). Postoperative immobilisation for 3 weeks in Gilchrists sling was followed by active-assistive step-by-step mobilisation. A speedy rehabilitation was planned after 6 weeks, but at this time the patient was doing strength training, swimming, pull-ups and press-ups at his own responsibility. Normal mobility and previous sports activity were achieved in spite of the early and extremely high stress. We assume that the very strong and secure reinsertion technique with 4 mattress sutures, Mason-Allen sutures and doubling of the tendon close to the foot print region may be the reason for the good result in spite of the massive and early loading.

Introduction Controversy remains regarding the optimal treatment method and postoperative rehabilitation of acute Achilles tendon ruptures. In this study, pedobarographic assessments of surgical and conservative treatments were compared. Material and methods A prospective assessment was made of 16 patients (eight surgical, eight conservative) and eight healthy controls using a plantar pressure measurement system. Biomechanical gait parameters were obtained using the Footscan dynamic gait analysis system. Kruskal–Wallis and Mann–Whitney U-tests were used for the evaluation of data. Results Nineteen males and five females were assessed, with an average age of 42.0±11.9 years. Follow-up was completed in 16 patients. No statistically significant difference was determined between the two treatment groups with regard to the gait analysis, but a difference was observed with the control group (P<0.001). All patients were able to resume their prior activities after 6 months and regained normal ranges of motion, with a high rate of satisfaction. Most of the patients (75%) were able to return to their pre-injury level of activities. Conclusion Satisfactory results were obtained through conservative treatment of acute ruptures of the Achilles tendon. No significant differences or complications were observed in the group managed conservatively versus the group treated surgically. Further studies including 3D gait analyses and tendon biomechanical research are required to further investigate this issue. PMID:27621640

The susceptibility of the undescended testis to malignant transformation is well documented. The most common location of the undescended testis is within the inguinal canal, with only a minority located within the abdominal cavity. When a testicular mass develops, the risk of torsion increases. We describe a large intra-abdominal testicular seminoma that had undergone torsion, rupture and haemorrhage, presenting as an acute abdomen. A 30 year old man presented to the emergency department with right iliac fossa pain. Computed tomography in the emergency department showed haemoperitoneum and a torted large left testicular mass, likely malignant. The patient underwent laparotomy and excision of the mass. Histologic examination revealed a grossly enlarged seminomatous testis which had torted and ruptured. While pre-operative imaging diagnosis of an intra-abdominal testicular seminoma has been published, reports are few. To the best of the author’s knowledge pre-operative imaging diagnosis of a malignant testicular mass with torsion and intra-abdominal haemorrhage presenting as an acute abdomen has not been described before.

Clinical Scenario: There are 2 approaches available for surgical repair of the Achilles tendon: open or percutaneous. However, there is controversy over which repair is superior. Focused Clinical Question: Which type of surgery is better in providing the best overall patient outcome, open or percutaneous repair, in physically active men and women with acute Achilles tendon ruptures? Summary of Search, "Best Evidence" Appraised, and Key Findings: The literature was searched for studies of level 3 evidence or higher that investigated the effectiveness of open repair versus percutaneous repair on acute Achilles tendon ruptures in physically active men and women. The literature search resulted in 3 studies for possible inclusion. All 3 good-quality studies were included. Clinical Bottom Line: There is supporting evidence to indicate that percutaneous repair is the best option for Achilles tendon surgery when it comes to the physically active population. Percutaneous repair has faster surgery times, less risk of complications, and faster recovery times over having an open repair, although it is acknowledged that every patient has a different situation and best individual option may vary patient to patient.

Intravital visualization of thrombopoiesis revealed that formation of proplatelets, which are cytoplasmic protrusions in bone marrow megakaryocytes (MKs), is dominant in the steady state. However, it was unclear whether this is the only path to platelet biogenesis. We have identified an alternative MK rupture, which entails rapid cytoplasmic fragmentation and release of much larger numbers of platelets, primarily into blood vessels, which is morphologically and temporally different than typical FasL-induced apoptosis. Serum levels of the inflammatory cytokine IL-1α were acutely elevated after platelet loss or administration of an inflammatory stimulus to mice, whereas the MK-regulator thrombopoietin (TPO) was not elevated. Moreover, IL-1α administration rapidly induced MK rupture–dependent thrombopoiesis and increased platelet counts. IL-1α–IL-1R1 signaling activated caspase-3, which reduced plasma membrane stability and appeared to inhibit regulated tubulin expression and proplatelet formation, and ultimately led to MK rupture. Collectively, it appears the balance between TPO and IL-1α determines the MK cellular programming for thrombopoiesis in response to acute and chronic platelet needs. PMID:25963822

A 74-year-old woman who had undergone aortic valve replacement with an Ionescu-Shiley bioprosthesis was evaluated and treated because aortic insufficiency developed after the application of the Heimlich maneuver. Pathologic examination of the explanted valve disclosed a cuspid perforation and an adjacent tear of a second cusp at its insertion into the valve strut. Patients with unexplained acute prosthetic insufficiency should be questioned as to whether the Heimlich maneuver has been previously performed.

Acute Achilles tendon rupture is one of the most common tendon injuries in adults. We hypothesized that Platelet-Rich Plasma (PRP) can be used as biological augmentation for surgical treatment of acute Achilles tendon rupture. Our study is a prospective randomized controlled trial. Patients with acute Achilles tendon rupture undergoing surgical repair were randomly assigned into either control group or PRP group. End-to-end modified Krackow suture was performed in both groups. In the PRP group, PRP was injected into the paratenon sheath and around the ruptured tissue after the tendon was repaired. Postoperatively we evaluated isokinetic muscle strength at 3, 6, 12, and 24 months. In addition, ankle ROM, calf circumference, Leppilahti score, and the SF-36 score were evaluated at 6, 12, and 24 months after operation. At 3 months, the PRP group had better isokinetic muscle. The PRP group also achieved higher SF-36 and Leppilahti scores at 6 and 12 months. At 24 months, the PRP group had an improved ankle range of motion compared to the control group. Our study results suggest that PRP can serve as a biological augmentation to acute Achilles tendon rupture repair and improves both short and midterm functional outcomes. PMID:28116306

Imaging studies of traumatic brain injury demonstrate that the cerebellum is often affected. We aim to examine fractional anisotropy alteration in acute-phase mild traumatic brain injury patients in cerebellum-related white matter tracts. This prospective study included 47 mild traumatic brain injury patients in the acute stage and 37 controls. MR imaging and neurocognitive tests were performed in patients within 7 days of injury. White matter integrity was examined by using diffusion tensor imaging. We used three approaches, tract-based spatial statistics, graphical-model-based multivariate analysis, and region-of-interest analysis, to detect altered cerebellar white matter integrity in mild traumatic brain injury patients. Results from three analysis methods were in accordance with each other, and suggested fractional anisotropy in the middle cerebellar peduncle and the pontine crossing tract was changed in the acute-phase mild traumatic brain injury patients, relative to controls (adjusted p-value < 0.05). Higher fractional anisotropy in the middle cerebellar peduncle was associated with worse performance in the fluid cognition composite (r = -0.289, p-value = 0.037). Altered cerebellar fractional anisotropy in acute-phase mild traumatic brain injury patients is localized in specific regions and statistically associated with cognitive deficits detectable on neurocognitive testing.

Alternate-level-of-care (ALC) days represent hospital beds that are taken up by patients who would more appropriately be cared for in other settings. ALC days have been found to be costly and may result in worse functional outcomes, reduced motor skills and longer lengths of stay in rehabilitation. This study examines the factors that are associated with acute care ALC days among patients with acquired brain injury (ABI). We used the Discharge Abstract Database to identify patients with ABI using International Classification of Disease-10 codes. From fiscal years 2007/08 to 2009/10, 17.5% of patients with traumatic and 14% of patients with non-traumatic brain injury had at least one ALC day. Significant predictors include having a psychiatric co-morbidity, increasing age and length of stay in acute care. These findings can inform planning for care of people with ABI in a publicly funded healthcare system.

Focal neocortical brain injuries lead to functional alterations, which can spread beyond lesion-neighboring brain areas. The undamaged hemisphere and its associated disturbances after a unilateral lesion, so-called transhemispheric diaschisis, have been progressively disclosed over the last decades; they are strongly involved in the pathophysiology and, potentially, recovery of brain injuries. Understanding the temporal dynamics of these transhemispheric functional changes is crucial to decipher the role of the undamaged cortex in the processes of functional reorganization at different stages post-lesion. In this regard, little is known about the acute-subacute processes after 24-48 h in the brain hemisphere contralateral to injury. In the present study, we performed a controlled cortical impact to produce a unilateral traumatic brain injury (TBI) in the motor and somatosensory cortex of mice. In vitro extracellular multi-unit recordings from large neuronal populations, together with single-cell patch-clamp recordings in the cortical network contralateral to the lesion, revealed a strong, but transient, neuronal hyperactivity as early as 24-48 h post-TBI. This abnormal excitable state in the intact hemisphere was not accompanied by alterations in neuronal intrinsic properties, but it was associated with an impairment of the phasic gamma aminobutyric acid (GABA)ergic transmission and an increased expression of GABAA receptor subunits related to tonic inhibition exclusively in the contralateral hemisphere. These data unravel a series of early transhemispheric functional alterations after diffuse unilateral cortical injury, which may compensate and stabilize the disrupted brain functions. Therefore, our findings support the hypothesis that the undamaged hemisphere could play a significant role in early functional reorganization processes after a TBI.

Objective To identify an appropriate diagnostic tool for the early diagnosis of Acute Traumatic Coagulopathy (ATC) and validate this modality through prediction of transfusion requirements in trauma hemorrhage. Design Prospective observational cohort study Setting Level 1 trauma centre Patients Adult trauma patients who met the local criteria for full trauma team activation. Exclusion criteria included emergency department (ED) arrival >2 hours after injury, >2000ml of intravenous fluid before ED arrival or transfer from another hospital. Interventions None Measurements Blood was collected on arrival in ED and analysed with laboratory prothrombin time (PT), point of care (PoC) PT and rotational thromboelastometry (ROTEM). Prothrombin ratio (PTr) was calculated and ATC defined as laboratory PTr>1.2. Transfusion requirements were recorded for the first 12 hours following admission. Main Results 300 patients were included in the study. Laboratory PT results were available at median 78 (62-103) minutes. PoC PTr had reduced agreement with laboratory PTr in patients with ATC, with 29% false negative results. In ATC the ROTEM Clot Amplitude at 5 minutes (CA5) was diminished by 42% and this persisted throughout clot maturation. ROTEM clotting time was not significantly prolonged. A CA5 threshold ≤35mm had a detection rate of 77% for ATC with a false positive rate of 13%. Patients with CA5 ≤35mm were more likely to receive red cell (46% vs 17%, p<0.001) and plasma (37% vs 11%, p<0.001) transfusions. The CA5 could identify patients who would require massive transfusion (detection rate of 71%, vs 43% for PTr >1.2, p<0.001). Conclusions In trauma hemorrhage PTr is not rapidly available from the laboratory and PoC devices can be inaccurate. ATC is functionally characterised by a reduction in clot strength. With a threshold of CA5 ≤35mm ROTEM can identify ATC at 5 minutes and predict the need for massive transfusion. PMID:21765358

There is a lack of consensus regarding the optimal surgical approach and fixation method for distal biceps tendon ruptures. The purpose of this study was to conduct a systematic review comparing the results of the various surgical approaches and repair techniques for acute distal biceps tendon ruptures. We searched the MEDLINE, Cochrane, and Embase databases for all published randomized controlled trials, prospective cohort studies, or case series that involved primary repairs of acute distal biceps tendon ruptures with use of a cortical button, intraosseous screws, suture anchors, or bone tunnels for fixation. Exclusion criteria included case reports, cadaveric studies, repairs of partial ruptures, revision repairs, and multiple methods of fixation in the same patient. Statistical analysis was performed with use of the chi-square test. Twenty-two studies met the inclusion criteria. The total number of patients was 494 (498 elbows). The complication rate was 24.5% (122 of 498 elbows) overall, and it was 23.9% (seventy-eight of 327) for one-incision procedures and 25.7% (forty-four of 171) for two-incision procedures (p = 0.32). The complication rate was 26.4% (seventy-five of 284) for suture anchors, 20.4% (thirty-four of 167) for bone tunnels, 44.8% (thirteen of twenty-nine) for intraosseous screws, and 0% (zero of eighteen) for cortical button fixation. The complication rate for use of bone tunnels was significantly lower than that for intraosseous screws (p < 0.01). Similarly, the cortical button method proved superior to intraosseous screws (p = 0.01). The most common complication was lateral antebrachial cutaneous nerve neurapraxia (9.6% across all studies, 11.6% for one incision, and 5.8% for two incisions). The complication rate did not differ significantly between one and two-incision distal biceps repairs; however, the bone tunnel and cortical button methods had significantly lower complication rates compared with suture anchors and intraosseous screws

Traumatic brain injury (TBI) is a major cause of death and disability worldwide. Progesterone has been shown to improve neurologic outcome in multiple experimental models and two early-phase trials involving patients with TBI. We conducted a double-blind, multicenter clinical trial in which patients with severe, moderate-to-severe, or moderate acute TBI (Glasgow Coma Scale score of 4 to 12, on a scale from 3 to 15, with lower scores indicating a lower level of consciousness) were randomly assigned to intravenous progesterone or placebo, with the study treatment initiated within 4 hours after injury and administered for a total of 96 hours. Efficacy was defined as an increase of 10 percentage points in the proportion of patients with a favorable outcome, as determined with the use of the stratified dichotomy of the Extended Glasgow Outcome Scale score at 6 months after injury. Secondary outcomes included mortality and the Disability Rating Scale score. A total of 882 of the planned sample of 1140 patients underwent randomization before the trial was stopped for futility with respect to the primary outcome. The study groups were similar with regard to baseline characteristics; the median age of the patients was 35 years, 73.7% were men, 15.2% were black, and the mean Injury Severity Score was 24.4 (on a scale from 0 to 75, with higher scores indicating greater severity). The most frequent mechanism of injury was a motor vehicle accident. There was no significant difference between the progesterone group and the placebo group in the proportion of patients with a favorable outcome (relative benefit of progesterone, 0.95; 95% confidence interval [CI], 0.85 to 1.06; P=0.35). Phlebitis or thrombophlebitis was more frequent in the progesterone group than in the placebo group (relative risk, 3.03; CI, 1.96 to 4.66). There were no significant differences in the other prespecified safety outcomes. This clinical trial did not show a benefit of progesterone over placebo in the

Patients with an acute Achilles tendon rupture (ATR) take a long time to heal, have a high incidence of deep vein thrombosis (DVT) and widely variable functional outcomes. This variation in outcome may be explained by a lack of knowledge of adverse factors, and a subsequent shortage of appropriate interventions. A total of 111 patients (95 men, 16 women; mean age 40.3, standard deviation 8.4) with an acute total ATR were prospectively assessed. At one year post-operatively a uniform outcome score, Achilles Combined Outcome Score (ACOS), was obtained by combining three validated, independent, outcome measures: Achilles tendon Total Rupture Score, heel-rise height test, and limb symmetry heel-rise height. Predictors of ACOS included treatment; gender; age; smoking; body mass index; time to surgery; physical activity level pre- and post-injury; symptoms; quality of life and incidence of DVT. There were three independent variables that correlated significantly with the dichotomised outcome score (ACOS), while there was no correlation with other factors. An age of less than 40 years old was the strongest independent predictor of a good outcome one year after ATR (odds ratio (OR) 0.20, 95% confidence interval (CI) 0.08 to 0.51), followed by female gender (OR) 4.18, 95% CI 1.01 to 17.24). Notably, patients who did not have a DVT while immobilised post-operatively had a better outcome (OR 0.31, 95% CI 0.12 to 0.80). Over the age of 40 years, male gender and having a DVT while immobilised are independent negative predictors of outcome in patients with an acute ATR.

To survey the risk factors for early death of patients with acute severe traumatic cervical spinal cord injury. A retrospective analysis of data of consecutive patients with acute severe traumatic cervical spinal cord injury admitted from January 1st 1994 to October 1st 2012 were made. The patients died within 30 days or not were allocated for death group or survival group. The risk factors for early death were analyzed through univariate analysis and logistic analysis. Among 1093 patients with acute traumatic cervical spinal cord injury, 352 patients with severe injury were included, and the early death rate was 14.49% (51/352). The leading causes of spinal cord injury were vehicle accidents (153 cases) and falls (117 cases). The main causes of early death were respiratory failure (16 cases), multiple organ failure (MOF, 14 cases) and gastrointestinal bleeding (11 cases). Combining the results of univariate and logistic analysis, it was found that high acute physiology and chronic health evaluation II(APACHEII) score [>15, odds ratio (OR)=11.595, P=0.000], high damage level (OR=3.519, P=0.032), hyponatremia (OR=6.316, P=0.000), neurogenic shock (OR=6.209, P=0.000), pulmonary infection (OR=14.627, P=0.000) and tracheostomy (OR=8.983, P=0.000) were risk factors for early death of patients with acute severe traumatic cervical spinal cord injury, however, the impact of gender, age, surgery, fracture and dislocation, high central fever, and administration of steroids on early death of patients with acute severe traumatic cervical spinal cord injury were uncertain. The factors reflecting disease severity and occurrence of related complications were more important in predicting the early death among patients with acute severe traumatic cervical spinal cord injury, while the influence of age, surgical manipulation etc. were minor factors.

A 58-year-old male with untreated hypertension was found dead in his car after a traffic accident on his way to the office. Emergency head CT showed diffuse subarachnoid hemorrhage at cerebral base. On autopsy examination, traumatic injuries were seen on his face and lower extremities. The skull was not fractured and there were no brain contusions except subscalp bleeding at the frontal head. The brain weighed 1510g and showed diffuse subarachnoid hemorrhage due to a rupture of the left vertebral artery (VA). Histopathological examination using serial step sections of every 0.1mm of the whole VA revealed multiple arterial dissections (AD) with fresh and old states at bilateral VA. Previous dissections at the basilar artery and internal carotid artery were also observed. The symptoms that he reported a week before the accident, left sided headache and shoulder pains, could have come from previous dissections. We concluded that the AD occurred while driving and was the cause of death, with the car accident then being caused by the stroke. Other specific histopathological findings were medial degeneration and serrate changes of the internal elastic lamina which resembled lesion of the segmental arterial mediolysis. These would suggest a pathogenesis of intracranial AD. Differential diagnosis of subarachnoid hemorrhage from the ruptured VA, distinguishing between idiopathic AD and traumatic trilaminar rupture, is still a difficult matter in forensic autopsy. However, this serial step sections procedure could be useful for the morphological differentiation.
Background Acute low back pain is a very common symptom and reason for many medical consultations. In some unusual circumstances it could be linked to a rare aetiology. Case presentation We report a 70-year-old man with an 8-month history of left posterior thigh and leg pain who had sudden confusion after a fall from standing. It was due to cerebral fat embolism suspected by computed tomography scan, later confirmed by brain magnetic resonance imaging (MRI). A spinal MRI scan was then performed and revealed a sacral fracture which drained into an unknown perineurial cyst (Tarlov cyst). Under medical observation the patient fully recovered within three weeks. Conclusions Sacral perineurial cysts are rare, however they remain a potential cause of lumbosacral radiculopathy.

We present a case of double post acute myocardial infarction complication: ventricular septal defect and acute and severe mitral insufficiency. As a consequence of the delay in the diagnosis, the patient developed pulmonary hypertension with values at the systemic level. The patient underwent surgery in order to close the ventricular septal defect and aneurysmectomy, resulting in posterior regression of mitral insufficiency and pulmonary circuit values became normal. The ethology, diagnosis, evolution and treatment of this exceptional association of acute post myocardial infarction complications are discussed.

Limited incision techniques for acute Achilles tendon ruptures have been developed in recent years to improve recovery and reduce postoperative complications compared with traditional open repair. The purpose of this retrospective cohort study was to analyze the clinical outcomes and postoperative complications between acute Achilles tendon ruptures treated using a percutaneous Achilles repair system (PARS [Arthrex, Inc, Naples, FL]) versus open repair and evaluate the overall outcomes for operatively treated Achilles ruptures. Between 2005 and 2014, 270 consecutive cases of operatively treated acute Achilles tendon ruptures were reviewed (101 PARS, 169 open). Patients with Achilles tendinopathy, insertional ruptures, chronic tears, or less than 3-month follow-up were excluded. Operative treatment consisted of a percutaneous technique (PARS) using a 2-cm transverse incision with FiberWire (Arthrex, Inc, Naples, FL) sutures or open repair using a 5- to 8-cm posteromedial incision with FiberWire in a Krackow fashion reinforced with absorbable sutures. Patient demographics were recorded along with medical comorbidities, activity at injury, time from injury to surgery, length of follow-up, return to baseline activities by 5 months, and postoperative complications. The most common activity during injury for both groups was basketball (PARS: 39%, open: 47%). A greater number of patients treated with PARS were able to return to baseline physical activities by 5 months compared with the open group (PARS: 98%, open: 82%; P = .0001). There were no significant differences (P > .05) between groups in rates of rerupture (P = 1.0), sural neuritis (P = .16), wound dehiscence (P = .74), superficial (P = .29) and/or deep infection (P = .29), or reoperation (P = .13). There were no deep vein thromboses (DVTs) or reruptures in either group. In the PARS group, there were no cases of sural neuritis, 3 cases (3%) of superficial wound dehiscence, and 2 reoperations (2%) for superficial

Abstract Rationale: Ventricular double rupture (VDR) is a rare but lethal mechanical complication of acute myocardial infarction (AMI). The early identification and timely treatment of VDR remain challenging problems. We present a case of AMI with VDR and briefly review the characteristics and prognosis of this life-threatening disease. Patient concerns and Diagnoses: A 77-year-old male presented to our hospital with a 4-day history of severe dizziness, mild chest tightness, and dyspnea. An inferior AMI was diagnosed. Interventions and Outcomes: On the second hospital day, hypotension and a new cardiac murmur was found. The emergency echocardiographic study disclosed a ventricular septal defect. Soon after that the patient suddenly died of ventricular free-wall rupture. Lessons: In patients with AMI complicated by a septal perforation in the apical region, close to the septum-free wall junction, special attention should be paid to the great risk of VDR. Other high risk factors included advanced age, delayed reperfusion, and inferior infarction. Sufficient evaluation of the risk factors, close monitoring of vital signs, early identification of the specific symptoms, and timely treatment are the key points for the effective prediction and prevention of VDR.

Ventricular septal rupture (VSR) in the acute myocardial infarction (AMI) is a rare but very serious complication, still associated with high mortality, despite significant improvements in pharmacological and surgical treatment. Therefore, hybrid approaches are introduced as new therapeutical options. We present an urgent hybrid approach, consisting of the initial percutaneous coronary intervention (PCI) of the infarct-related artery, followed by immediate surgical closure of the ventricular septal rupture, for treatment of high risk, hemodynamically unstable female patient with AMI caused by one-vessel disease and complicated by VSR and cardiogenic shock. Since the operative risk was also very high (EUROSCORE II 37%), this therapeutic decision was based on the assumption that preoperative PCI could promptly establish blood flow and thereby lessen the risks, duration and complexity of urgent cardiosurgical intervention, performed on the same day. This approach proved to be successful and the patient was discharged from the hospital on the fifteenth postoperative day in stable condition. In selected cases, with high operative risk and unstable hemodynamic state due to AMI complicated by VSR, urgent hybrid approach consisting of the initial PCI followed by surgical closure of VSR may represent an acceptable treatment option and contribute to the treatment of this complex group of patients.

We reported three cases of ventricular septal rupture (VSR) complicating acute myocardial infarction (AMI), focusing on the causes, diagnosis, treatment and prevention. These three cases were diagnosed based on the findings of electrocardiogram, echocardiogram and blood myocardial markers, and were treated with conservative methods. These three cases were female, and all had history of hypertension and/or diabetes mellitus. In one case with age over 70, AMI was related to percutaneous coronary intervention of left anterior descending branch, and the stenosis of LAD resulted in AMI and subsequently VSR occurred, the patient’s condition worsened rapidly and the patient died after. Only one of the three cases survived the VSR. We concluded that the prognosis of VSR complicating AMI is associated with the causes, age, sex and comorbidities, and the prevention is critically important.

Gestational trophoblastic neoplasms (GTN) are proliferative degenerative disorders of placental elements and include complete or partial mole (90%), invasivemole (5-8%), choriocarcinoma (1-2%) and placental site tumor (1-2%). Chorioadenoma destruens is a trophoblastic tumor, characterized by myometrial invasion through direct extension or via venous channels. We present a case of invasive mole eroding uterus and uterine vasculature, causing sudden rupture of uterus with massive haemoperitoneum mimicking ectopic pregnancy. A 20 year old G1P0 at 6 weeks gestation presented in Casualty of Kasturba Hospital complaining of severe acute onset lower abdominal pain for one hour. Clinical examination revealed shock. Sonography suggested ectopic pregnancy and immediate exploratory laparotomy was decided. On laparotomy, 2000cc of haemoperitoneum was noted. Grape like vesicles protruding through fundal perforation with profuse active bleeding was seen. Bleeding persisted despite evacuation. Step wise uterine devascularisation failed to achieve haemostasis. Total abdominal hysterectomy was performed as a life saving measure.

Background Seizures triggered by acute injuries to the developing brain respond poorly to first-line medications that target the inhibitory chloride-permeable GABAA-receptor. Neuronal injury is associated with profound increases in cytoplasmic chloride ([Cl−]i) resulting in depolarizing GABA signaling, higher seizure propensity and limited efficacy of GABAergic anticonvulsants. The Na+-K+-2Cl− (NKCC1) co-transporter blocker bumetanide reduces [Cl−]i and causes more negative GABA equilibrium potential in injured neurons. We therefore tested both the acute and chronic efficacy of bumetanide on early post-traumatic ictal-like epileptiform discharges and epileptogenesis. Methods Acute hippocampal slices were used as a model of severe traumatic brain injury and post-traumatic epileptogenesis. Hippocampal slices were then incubated for three weeks. After a one week latent period slice cultures developed chronic spontaneous ictal-like discharges. The anticonvulsant and antiepileptogenic efficacy of bumetanide, phenobarbital and the combination of these drugs was studied. Results Bumetanide reduced the frequency and power of early post-traumatic ictal-like discharges in vitro and enhanced the anticonvulsant efficacy of phenobarbital. Continuous two-three week administration of bumetanide as well as phenobarbital in combination with bumetanide failed to prevent post-traumatic ictal-like discharges and epileptogenesis. Conclusions Our data demonstrate a persistent contribution of NKCC1 co-transport in post-traumatic ictal-like activity, presumably as a consequence of chronic alterations in neuronal chloride homeostasis and GABA-mediated inhibition. New strategies for more effective reduction in post-traumatic and seizure-induced [Cl−]i accumulation could provide the basis for effective treatments for post-traumatic epileptogenesis and the resultant seizures.

To determine the frequency of anterolateral ligament (ALL) injury in patients with acute anterior cruciate ligament (ACL) rupture and to analyse its associated injury patterns. Ninety patients with acute ACL rupture for which MRI was obtained within 8 weeks after the initial trauma were retrospectively identified. Two radiologists assessed the status of the ALL on MRI by consensus. The presence or absence of an ALL abnormality was compared with the existence of medial and lateral meniscal tears diagnosed during arthroscopy. Associated collateral ligament and osseous injuries were documented with MRI. Forty-one of 90 knees (46 %) demonstrated ALL abnormalities on MRI. Of 49 knees with intact ALL, 15 (31 %) had a torn lateral meniscus as compared to 25 torn lateral menisci in 41 knees (61 %) with abnormal ALL (p = 0.008). Collateral ligament (p ≤ 0.05) and osseous injuries (p = 0.0037) were more frequent and severe in ALL-injured as compared with ALL-intact knees. ALL injuries are fairly common in patients with acute ACL rupture and are statistically significantly associated with lateral meniscal, collateral ligament and osseous injuries. • ALL injuries are fairly common in patients with acute ACL rupture. • ALL injuries are highly associated with lateral meniscal and osseous injuries. • MRI assessment of ACL-injured knees should include evaluation of the ALL.

Acute Achilles tendon rupture can be treated conservatively or surgically. Open surgery restores tendon continuity but carries a risk of skin complications. Tenolig(®) is a device designed for the percutaneous biological treatment of acute Achilles tendon rupture. Earlier studies found high rates of recurrent tears and nerve injury after Tenolig(®) repair. We hypothesised that intra-operative ultrasonography during Tenolig(®) repair would decrease the post-operative complication rate and improve functional outcomes. We studied 75 consecutive patients with a mean age of 39.9 years. The injury was sports-related in 82.8% of cases. Mean distance from the calcaneal tendon attachment to the tear was 5cm and mean time from injury to repair was 4.2 days. All patients underwent Tenolig(®) repair under ultrasound guidance followed by early rehabilitation therapy with partial weight bearing started after 3 weeks. Mean follow-up was 20.7 months and no patient was lost to follow-up. A single patient (1.3%) experienced rerupture and none had permanent sural nerve damage. Mean time to sports resumption was 8.6 months, with two-thirds of patients returning to their previous level of sporting activities. The mean AOFAS functional score was 95 and the mean ATRS score was 91.3. Our experience suggests that intra-operative ultrasonography, a non-invasive, widely available, and accurate tool, provided improved control of Tenolig(®) suture position. Ultrasonography provided valuable guidance during this demanding procedure and allowed the very early initiation of rehabilitation therapy. Another crucial factor is patient education about the physical therapy programme. Attention to this point allowed us to obtain robust and reliable functional outcomes in a population predominantly composed of athletes. Level IV. Copyright © 2014 Elsevier Masson SAS.

Open fibrin gluing is reported to enable anatomical reconstruction with less soft tissue compromise than suture repair. Our main objective was to compare the complication rate, function, pain and disability of the two operative approaches of percutaneous suture using the Paessler technique and open fibrin gluing. Sixty-four patients (two centres, retrospective cohort study, 2000-2009) who had undergone acute Achilles tendon repair with either percutaneous suture (n = 27; 44 years) or open fibrin glue (n = 37; 45 years) took part in a follow-up examination after a median of 63 months (range, six to 180). Ankle range of motion, calf and ankle circumferences and return to work and sports activities were evaluated. Isokinetic und sonographic evaluation results were retrieved. Complications were noted in 22 patients (34 %). Delayed wound healing without evidence of surgical site infection was found in three patients in the fibrin group and two patients in the suture group. Postoperative scar tenderness described as pain at the rim of the shoe was significantly more frequent in the suture group (p = 0.03). Re-rupture requiring re-operation occurred in one patient. Transient paresthesia of the heel occurred in 12 patients. No sural nerve lesions were reported. There was no significant difference between groups regarding lower leg circumference, disability, or function. Ultrasound and isokinetic measurements did not reveal a significant difference between the two methods. The present study suggests that open fibrin gluing is a reasonable alternative to percutaneous repair of acute ruptures of the Achilles tendon and both techniques can yield reliably good results.

Background Acute Traumatic Coagulopathy (ATC) occurs after severe injury and shock and is associated with increased bleeding, morbidity and mortality. The effects of ATC and hemostatic resuscitation on outcome are not well-explored. The PRospective Observational Multicenter Major Trauma Transfusion (PROMMTT) study provided a unique opportunity to characterize coagulation and the effects of resuscitation on ATC after severe trauma. Methods Blood samples were collected upon arrival on a subset of PROMMTT patients. Plasma clotting factor levels were prospectively assayed for coagulation factors. These data were analyzed with comprehensive PROMMTT clinical data. Results There were 1198 patients with laboratory results of whom 41.6% were coagulopathic. Using International Normalized Ratio (INR)≥1.3, 41.6% (448) of patients were coagulopathic while 20.5% (214) were coagulopathic using partial thromboplastin time (PTT)≥35. Coagulopathy was primarily associated with a combination of an ISS>15 and a BD<−6 (P<.05). Regression modeling for INR-based coagulopathy shows that pre-hospital crystalloid (odds ratio (OR)=1.05), Injury Severity Score (ISS, OR=1.03), Glasgow Coma Scale (OR=0.93), heart rate (OR=1.08), systolic blood pressure (OR=0.96), base deficit (BD, OR=0.92) and temperature (OR=0.84) were significant predictors of coagulopathy (all P<.03). A subset of 165 patients had blood samples collected and coagulation factor analysis performed. Elevated ISS and BD were associated with elevation of aPC and depletion of factors (all P<.05). Reductions in factors I, II, V, VIII and an increase in aPC drive ATC (all p<.04). Similar results were found for PTT-defined coagulopathy. Conclusions ATC is associated with depletion of factors I, II, V, VII, VIII, IX and X and is driven by the activation of the protein C system. These data provide additional mechanistic understanding of the drivers of coagulation abnormalities after injury. Further understanding of the drivers of

Summary It is apparent that subarachnoid clots play an important role in the development of delayed vasospasm that is one of the major causes of mortality and morbidity in patients with acutely ruptured cerebral aneurysm. The purpose of this study is to compare the clearance of subarachnoid clots in the acute stage after the treatment with Guglielmi detachable coils (GDC) and after treatment with direct surgery. Forty-nine patients were treated by GDC embolization within four days of the ictus. After GDC embolization, adjunctive therapies, such as ventricular and/or spinal drainage (67%), intrathecal administration of urokinase (41%), continuous cisternal irrigation (16%), and external decompression (16%), were performed. Seventy-four surgically treated patients were subsequently treated by continuous cisternal irrigation with mock-CSF containing ascorbic acid for ten days. The clearance of subarachnoid clots was assessed by the Hounsfield number serial changes on the CT scans taken on days 0, 4, 7,10 after subarachnoid hemorrhage. The incidence of symptomatic vasospasm was lower in the GDC group (6%) than in the surgery group (12%). The clearance of subarachnoid clots from both the basal cistern and the Sylvian fissure was more rapid in the GDC cases than in the surgery cases in the first four days. Intrathecal administration of urokinase accelerated the clearance significantly. GDC embolization followed by intrathecal administration of thrombolytic agents accelerates the reduction of subarachnoid clots and favorably acts to prevent delayed vasospasm. PMID:20663379

The present study was designed to determine whether a low dose of acute ethanol administration could attenuate cognitive deficits associated with traumatic brain injury. Adult male rats received oral administration of ethanol or drinking water 2 h prior to surgery to produce a blood ethanol concentration of 100 mg% and then received bilateral contusion injuries of the medial prefrontal cortex. Seven days after surgery, the rats began 10 days of testing for acquisition of spatial localization in the Morris water maze where they were required to find a hidden platform to escape from the water. The results indicate that the rats given ethanol at the time of injury later spent significantly less time searching for the hidden platform than their water-treated counterparts. On a memory probe test given on the final day of testing, in which the platform was removed from the pool, rats given the ethanol spent more time in the area where the platform had been located indicating that they learned its location better than the lesion/water controls. In addition, acute ethanol treatment reduced some of the histopathology that typically occurs following severe contusion of the medial frontal cortex but did not attenuate post-traumatic formation of edema. These results indicate that acute ethanol intoxication can reduce the severity of cognitive impairments caused by contusive traumatic brain injury and support the contention that there is a dose-response relationship of acute ethanol intoxication in the setting of traumatic brain injury.

Abstract Introduction: Abdominal compartment syndrome (ACS) after endovascular repair (EVAR) of rupture abdominal aortic aneurysm (rAAA) is a rare emergency situation, which has a high mortality. However, the progression of ACS is rapid and the diagnosis is usually been delayed, which increase the difficulties in treatment and affect the prognosis. We describe a case of a sever complication (acute intestinal necrosis) resulting from ACS after endovascular repair of rAAA. Clinical Finding: An elderly man, 81 years old, complained a sudden lower abdominal and back pain without any predisposing cause. He had a history of hypertension for 20 years without any regular anti-hypertensive therapy. Physical Examination revealed that the blood pressure was 89/54 mmHg, pulse was 120/min, oxygen saturation was 91%. The abdominal ultrasound and the CTA (computed tomography angiography) scan revealed a rAAA. Emergency EVAR under general anesthesia was performed for this patient. Diagnosis: Fourteen hours after endovascular repair, sudden decreased of blood pressure (70/50 mmHg) and oxygen saturation (70%) was observed. ACS or bleeding of retroperitoneal space was diagnosed. Interventions: Abdominal laparotomy was immediately performed. ACS was verified and a severe complication (acute intestinal necrosis) was observed, intestinal resection was performed for this patient. Outcomes: Unfortunately, this patient died after operation because of multi-organ failure in a very short period, which is very rare regarding to this condition. Surgical pathology, diagnosis and management were discussed. Conclusion: ACS was occurred with a severe complication (acute intestinal necrosis) in a very short period, which is very rare regarding to this condition after EVAR, it reminds us the severe result of ACS and more methods to prevent it happened after surgical management.

We describe the first reported survivor of a delayed trans-diaphragmatic hepatic rupture complicated by acute superior vena cava (SVCS) and thoracic compartment syndromes (TCS). A thirty one year old male was involved in a boating accident. The patient was diagnosed with a grade IV liver laceration, which was initially managed with both angio-embolization and open surgical repair. Exactly one month from admission, the patient presented with an abrupt cardiac arrest, which was further complicated by a SVCS and TCS. The SVCS was managed with bilateral thoracostomies which revealed a delayed trans-diaphragmatic hepatic rupture into the right chest cavity. The TCS was managed with a decompressive thoraco-abdominal incision. The patient survived and is now leading a normal life. Our success was largely due to an integrated trauma system of physicians, nurses and technicians that prompted the early recognition of two potentially life threatening complications of a delayed trans-diaphragmatic hepatic rupture.

Acute coagulopathy is a serious complication of traumatic brain injury (TBI) and is of uncertain etiology because of the complex nature of TBI. However, recent work has shown a correlation between mortality and abnormal hemostasis resulting from early platelet dysfunction. The aim of the current study was to develop and characterize a rodent model of TBI that mimics the human coagulopathic condition so that mechanisms of the early acute coagulopathy in TBI can be more readily assessed. Studies utilizing a highly reproducible constrained blunt-force brain injury in rats demonstrate a strong correlation with important postinjury pathological changes that are observed in human TBI patients, namely, diminished platelet responses to agonists, especially adenosine diphosphate (ADP), and subarachnoid bleeding. Additionally, administration of a direct thrombin inhibitor, preinjury, recovers platelet functionality to ADP stimulation, indicating a direct role for excess thrombin production in TBI-induced early platelet dysfunction.

Bodybuilding is a high-risk sport for distal triceps tendon ruptures. Management, especially in high-demanding athletes, is operative with suture anchor refixation technique being frequently used. However, the rate of rerupture is high due to underlying poor tendon quality. Thus, additional augmentation could be useful. This case report presents a reconstruction technique for a complete traumatic distal triceps tendon rupture in a bodybuilder with postoperative biomechanical assessment. A 28-year-old male professional bodybuilder was treated with a synthetic augmented suture anchor reconstruction for a complete triceps tendon rupture of his right dominant elbow. Postoperative biomechanical assessment included isokinetic elbow strength and endurance testing by using multiple angular velocities to simulate the “off-season” and “precompetition” phases of training. Eighteen months postoperatively and after full return to training, the biomechanical assessment indicated that the strength and endurance of the operated elbow joint was fully restored with even higher ratings compared to the contralateral healthy arm. The described reconstruction technique can be considered as an advisable option in high-performance athletes with underlying poor tendon quality due to high tensile strength and lack of donor site morbidity, thus enabling them to restore preinjury status and achieve safe return to sports.

Although early accelerated rehabilitation is recommended for the treatment of acute Achilles tendon rupture, most traditional rehabilitation techniques require some type of brace. We retrospectively analyzed 44 feet of 44 patients (25 male and 19 female) with a mean age of 31.8 years who had an acute Achilles tendon rupture related to athletic activity. Patients had been treated by a double side-locking loop suture (SLLS) technique using double antislip knots between stumps and had undergone early accelerated rehabilitation, including active and passive range of motion exercises on the day following the operation and full weight-bearing at 4 weeks. No brace was applied postoperatively. The evaluation criteria included the American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Scale (AOFAS) score; active plantar flexion and dorsiflexion angles; and the intervals between surgery and the time when patients could walk normally without any support, perform double-leg heel raises, and perform 20 continuous single-leg heel raises of the operated foot. Despite postoperative early accelerated rehabilitation, the AOFAS score and active dorsiflexion angles improved over time (6, 12, and 24 weeks and 2 years). A mean of 4.3 ± 0.6 weeks was required for patients to be able to walk normally without any support. The mean period to perform double-leg heel raises and 20 continuous single-leg heel raises of the injured foot was 8.0 ± 1.3 weeks and 10.9 ± 2.1 weeks, respectively. All patients, except one who was engaged in classical ballet, could return to their preinjury level of athletic activities, and the interval between operation and return to athletic activities was 17.1 ± 3.7 weeks. The double SLLS technique with double antislip knots between stumps adjusted the tension of the sutured Achilles tendon at the ideal ankle position and provided good clinical outcomes following accelerated rehabilitation after surgery without the use of a brace.

We review different causes, diagnoses, and treatment options of closed flexor tendon disruptions in the hand. A classification of closed tendon ruptures based on their mechanism includes traumatic tendon avulsion, spontaneous midsubstance rupture, attrition rupture, infiltrative tenosynovial rupture, and iatrogenic. Certain conditions result in tendon disruption inflicted by more than 1 of these etiologies. In rheumatoid arthritis, tendon rupture may result from attrition on an exposed rough surface, proliferative tenosynovial tendon infiltration, or steroid use.

A leading cause of maternal mortality in the first trimester is hemorrhage due to a ruptured ectopic pregnancy. With the advent of tube salvage surgery, ectopic pregnancies can be removed while ensuring hemostasis and preserving the integrity of the fallopian tube. A major drawback of tube salvage surgery is the significant risk of persistent trophoblastic tissue being left behind. We report a case of a 30year old female who presented to the ED with acute abdomen and hemoperitoneum due to a ruptured ectopic pregnancy. She was treated with salpingostomy and the pathologic report confirmed removal of the ectopic pregnancy. After an initially uneventful post-operative recovery, she presented to the ED 27days later with signs of acute abdomen and hemoperitoneum. Surgical intervention confirmed a ruptured ectopic pregnancy in the same site as previous, and salpingectomy was performed, after which the patient recovered without complications. The increased risk of persistent trophoblastic tissue associated with tube salvage surgery can lead to subsequent reoperation for tubal rupture. Patients undergoing these procedures should be closely monitored in the following weeks and undergo serial β-hCG testing in order to confirm successful removal of the ectopic.

Traumatic spinal injury is a major cause of morbidity and mortality worldwide. There is no agreed method of care. Neurological recovery in complete injury has been dismal. Aims and Objectives : The aim of this study is to determine the neurological recovery at discharge in traumatic spinal injury patients managed nonoperatively in our center. This was a prospective descriptive study carried out on traumatic spinal injury patients managed by neurosurgical unit in our center from August 2010 to July 2013. The unit started in July 2010 with virtually no available facilities for surgical care for these patients. All patients were managed nonoperatively. The unit recorded data of the patients in accident and emergency, intensive care unit, and wards using structured proforma. Data were analyzed using Epi Info 7 software. There were 76 patients studied of which 57 were males and 25 were females. Fifty three were caused by road traffic accident. Nineteen were complete injury. Patients with incomplete injuries did well at discharge. Completeness of injury significantly affected the outcome. The neurological recovery in incomplete spinal injuries in our study was good, but poor in complete injury. Conservative treatment should be adopted in developing countries in patients with poor resources and in centers where facilities are not available for adequate imaging and surgical care. Trauma system is imperative in our country.

Only a limited number of studies have investigated attention following pediatric head-injury. The present study examined sustained attention and processing speed in a group of children who had sustained a mild (n = 27), moderate (n = 33) or severe (n = 16) traumatic brain injury (TBI). No significant differences were evident between the TBI groups on reaction time measures. Results did show that the severe TBI group exhibited greater deficits in the area of sustained attention, in comparison to children with mild and moderate injuries, in the acute stage following traumatic brain injury. This difficulty may impact on the future development of skills dependent on intact attentional capacity.

Conservative management of acute Achilles tendon ruptures in a plantarflexed short leg cast or functional brace is a viable alternative to surgery. The ideal plantarflexion angle to allow the free ends of the tendon to oppose one another has not been clearly defined. The purpose of this cadaveric study was to define a plantarflexion angle where the free Achilles tendon ends reliably oppose one another. Ten cadaveric legs amputated at the distal femur were obtained. A laceration of the Achilles tendon was made 4 cm above the calcaneal insertion. A joint-spanning external fixator was placed across the knee. With differing degrees of knee flexion (0, 45, and 90 degrees), the diastasis between the free ends of the Achilles tendon was measured as the ankle was moved from 20 degrees of dorsiflexion to 30 degrees of plantarflexion (-20, -10, neutral, 10, 20, and 30 degrees). Regardless of knee flexion angle, the ankle plantarflexion angle where the free ends of the Achilles tendon opposed one another was 28.0 (95% confidence interval: 25.0-33.6) degrees. The ideal ankle angle in which to immobilize patients appears tightly clustered around 28 degrees of plantarflexion.

Although many meta-analyses comparing surgical intervention with conservative treatment have been conducted for acute Achilles tendon rupture, discordant conclusions are shown. This study systematically reviewed the overlapping meta-analyses relating to surgical versus conservative intervention of acute Achilles tendon rupture to assist decision makers select among conflicting meta-analyses, and to offer intervention recommendations based on the currently best evidence.Multiple databases were comprehensively searched for meta-analyses comparing surgical with conservative treatment of acute Achilles tendon rupture. Meta-analyses only comprising randomized controlled trials (RCTs) were included. Two authors independently evaluated the meta-analysis quality and extracted data. The Jadad decision algorithm was applied to ascertain which meta-analysis offered the best evidence.A total of 9 meta-analyses were included. Only RCTs were determined as Level-II evidence. The scores of Assessment of Multiple Systematic Reviews (AMSTAR) ranged from 5 to 10 (median 7). A high-quality meta-analysis with more RCTs was selected according to the Jadad decision algorithm. This study found that when functional rehabilitation was used, conservative intervention was equal to surgical treatment regarding the incidence of rerupture, range of motion, calf circumference, and functional outcomes, while reducing the incidence of other complications. Where functional rehabilitation was not performed, conservative intervention could significantly increase rerupture rate.Conservative intervention may be preferred for acute Achilles tendon rupture at centers offering functional rehabilitation, because it shows a similar rerupture rate with a lower risk of other complications when compared with surgical treatment. However, surgical treatment should be considered at centers without functional rehabilitation as this can reduce the incidence of rerupture.

Previous reports have suggested that knee flexion improves tendon edge apposition following acute rupture of the Achilles tendon. The aim of the present study was to determine, with use of ultrasonography, the effects of knee and ankle position on the Achilles tendon gap distance in patients with an acute rupture. Twenty-six patients with a unilateral acute complete Achilles tendon rupture that had been confirmed with ultrasonography were recruited within a week after the injury. The mean age at the time of presentation was forty-one years. Ultrasound measurements included the location of the rupture and the gap distance between the superficial tendon edges with the ankle in neutral and the knee extended. The gap distance was sequentially measured with the foot in maximum equinus at the ankle and with 0°, 30°, 60°, and 90° of knee flexion. The mean distance of the rupture from the calcaneal enthesis was 52 mm (range, 40 to 76 mm). The mean gap distance with the ankle in neutral and the knee extended was 12 mm (95% confidence interval, 10 to 13 mm). This distance decreased to 5 mm (95% confidence interval, 4 to 7 mm) when the foot was placed in maximum ankle equinus with 0° of knee flexion and to 4 mm (95% confidence interval, 3 to 5 mm) with 30° of knee flexion, 3 mm (95% confidence interval, 2 to 4 mm) with 60° of knee flexion, and 2 mm (95% confidence interval, 1 to 2 mm) with 90° of knee flexion. Expressing the reduction in gap distance with each successive position as a percentage of the gap distance with the knee extended and the ankle in neutral revealed a mean reduction of 55.7%, 64.4%, 75.4%, and 84.8% with maximum ankle equinus and 0°, 30°, 60°, and 90° of knee flexion, respectively. The difference in gap distance between each of these positions was significant (p < 0.05). Maximum ankle equinus alone significantly reduces the gap distance after acute Achilles tendon rupture. Increasing knee flexion further reduces the gap distance by small

A cystic artery aneurysm is a rare cause of hemobilia. Herein, we report two cases of acute cholecystitis with a ruptured cystic artery pseudoaneurysm. Two patients (a 69-year-old man and an 83-year-old man) were admitted to our hospital because of acute cholecystitis with gallstone impaction in the neck. Percutaneous transhepatic gallbladder drainage (PTGBD) was performed for both patients. After a few days of PTGBD, gallbladder hemorrhage was observed. Abdominal angiography showed cystic artery aneurysm. A transcatheter arterial embolization was therefore performed, followed by an open cholecystectomy.

Study Design Systematic review. Objective To determine the incidence, pathogenesis, and clinical outcomes related to neurogenic fevers following traumatic spinal cord injury (SCI). Methods A systematic review of the literature was performed on thermodysregulation secondary to acute traumatic SCI in adult patients. A literature search was performed using PubMed (MEDLINE), Cochrane Central Register of Controlled Trials, and Scopus. Using strict inclusion and exclusion criteria, seven relevant articles were obtained. Results The incidence of fever of all origins (both known and unknown) after SCI ranged from 22.5 to 71.7% with a mean incidence of 50.6% and a median incidence of 50.0%. The incidence of fever of unknown origin (neurogenic fever) ranged from 2.6 to 27.8% with a mean incidence of 8.0% and a median incidence of 4.7%. Cervical and thoracic spinal injuries were more commonly associated with fever than lumbar injuries. In addition, complete injuries had a higher incidence of fever than incomplete injuries. The pathogenesis of neurogenic fever after acute SCI is not thoroughly understood. Conclusion Neurogenic fevers are relatively common following an acute SCI; however, there is little in the scientific literature to help physicians prevent or treat this condition. The paucity of research underscored by this review demonstrates the need for further studies with larger sample sizes, focusing on incidence rate, clinical outcomes, and pathogenesis of neurogenic fever following acute traumatic SCI.

We present the design of an open randomized multi-centre study on surgical versus conservative treatment of acute Achilles tendon ruptures. The study is designed to evaluate the effectiveness of conservative treatment in reducing complications when treating acute Achilles tendon rupture. At least 72 patients with acute Achilles tendon rupture will be randomized to minimally invasive surgical repair followed by functional rehabilitation using tape bandage or conservative treatment followed by functional rehabilitation with use of a functional bracing system. Both treatment arms use a 7 weeks post-rupture rehabilitation protocol. Four hospitals in the Netherlands will participate. Primary end-point will be reduction in complications other than re-rupture. Secondary end-point will be re-rupturing, time off work, sporting activity post rupture, functional outcome by Leppilahti score and patient satisfaction. Patient follow-up will be 12 month. By making this design study we wish to contribute to more profound research on AT rupture treatment and prevent publication bias for this open-labelled randomized trial. ISRCTN50141196.

Over the past decade, public awareness of the long-term pathological consequences of traumatic brain injury (TBI) has increased. Such awareness has been stimulated mainly by reports of progressive neurological dysfunction in athletes exposed to repetitive concussions in high-impact sports such as boxing and American football, and by the rising number of TBIs in war veterans who are now more likely to survive explosive blasts owing to improved treatment. Moreover, the entity of chronic traumatic encephalopathy (CTE)—which is marked by prominent neuropsychiatric features including dementia, parkinsonism, depression, agitation, psychosis, and aggression—has become increasingly recognized as a potential late outcome of repetitive TBI. Annually, about 1% of the population in developed countries experiences a clinically relevant TBI. The goal of this Review is to provide an overview of the latest understanding of CTE pathophysiology, and to delineate the key issues that are challenging clinical and research communities, such as accurate quantification of the risk of CTE, and development of reliable biomarkers for single-incident TBI and CTE.

Mild Traumatic Brain Injury (mTBI) is a prominent public health issue. To date, subjective symptom complaints primarily dictate diagnostic and treatment approaches. As such, the description and qualification of these symptoms in the mTBI patient population is of great value. This manuscript describes the symptoms of mTBI patients as compared to controls in a larger study designed to examine the use of vestibular testing to diagnose mTBI. Five symptom clusters were identified: Post-Traumatic Headache/Migraine, Nausea, Emotional/Affective, Fatigue/Malaise, and Dizziness/Mild Cognitive Impairment. Our analysis indicates that individuals with mTBI have headache, dizziness, and cognitive dysfunction far out of proportion to those without mTBI. In addition, sleep disorders and emotional issues were significantly more common amongst mTBI patients than non-injured individuals. A simple set of questions inquiring about dizziness, headache, and cognitive issues may provide diagnostic accuracy. The consideration of other symptoms may be critical for providing prognostic value and treatment for best short-term outcomes or prevention of long-term complications. PMID:26727256

Over the past decade, public awareness of the long-term pathological consequences of traumatic brain injury (TBI) has increased. Such awareness has been stimulated mainly by reports of progressive neurological dysfunction in athletes exposed to repetitive concussions in high-impact sports such as boxing and American football, and by the rising number of TBIs in war veterans who are now more likely to survive explosive blasts owing to improved treatment. Moreover, the entity of chronic traumatic encephalopathy (CTE)--which is marked by prominent neuropsychiatric features including dementia, parkinsonism, depression, agitation, psychosis, and aggression--has become increasingly recognized as a potential late outcome of repetitive TBI. Annually, about 1% of the population in developed countries experiences a clinically relevant TBI. The goal of this Review is to provide an overview of the latest understanding of CTE pathophysiology, and to delineate the key issues that are challenging clinical and research communities, such as accurate quantification of the risk of CTE, and development of reliable biomarkers for single-incident TBI and CTE.

Ventricular septal rupture (VSR) remains an infrequent but devastating complication of acute myocardial infarction (AMI). The best time to undergo surgical repair is controversial and there is currently no risk stratification for patients with VSR to guide treatment. The purpose of this study was to review the clinical outcomes of 70 patients with VSR, to analyze the short-term prognosis factors of VSR following AMI, and to make a risk stratification for patients with VSR. A total of 70 consecutive VSR patients following AMI treated in our hospital from January 2002 to October 2010 were enrolled in this study retrospectively. The difference of clinical characteristics were observed between patients with VSR who survived ≤30 days and survived >30 days. We analyzed the short-term prognosis factors of VSR and established the short-term prognosis index of VSR (SPIV) based on the Logistic regression analysis to stratify patients with VSR. Among 12 354 patients with acute ST-segment elevation myocardial infarction, 70 (0.57%) patients (33 males and 37 females) were found to have VSR. The average age was (68.1±8.5) years. Fifty-four (77.1%) patients were diagnosed with an acute anterior infarction. Patients with VSR selected for surgical repair had better outcomes than patients treated conservatively; 1-year mortality 9.5% versus 87.8%, P < 0.005. Logistic regression analysis revealed that female (P = 0.013), anterior AMI (P = 0.023), non-ventricular aneurysm (P = 0.023), non-diabetes (P = 0.009), Killip class 3 or 4 (P = 0.022) and time from AMI to VSR less than 4 days (P = 0.027) were independent risk determinants for shortterm mortality. SPIV ≥9 indicates a high risk as the 30-day mortality is 77.4%; SPIV <8 indicates a low risk as the 30-day mortality is 28.6%; SPIV between 8 and 9 indicates a moderate risk. VSR remains a rare but devastating complication of AMI. The independent risk determinants for short-term mortality of VSR were female gender, anterior AMI

A 60-year-old man with chronic obstructive pulmonary disease and a heavy smoker and drinker presented to the emergency department with left-sided thoracoabdominal pain after falling down the stairs. Initial clinical findings were left-sided chest tenderness with no clinical evidence of subcutaneous emphysema. Twenty-four hours later the patient's respiratory distress increased—repeat chest X-ray showed a left gastrothorax indicative of a ruptured left hemi diaphragm. Diagnostic laparoscopy in the supine position via an umbilical port confirmed the presence of the stomach, spleen and splenic flexure of the colon in the left chest. Laparoscopic reduction of the stomach and colon was performed, but a small upper midline incision was required to reduce the spleen without injury. The diaphragmatic tear was repaired by direct open suture. The patient required a brief period of postoperative ventilation via a tracheostomy. The patient remained well at a 3-month follow-up visit.

A number of meta-analyses have been carried out to evaluate the effects of minimally invasive surgery (MIS) versus open surgery (OS) for acute Achilles tendon rupture. However, discordant findings were seen in these meta-analyses. The present study, performing a systematic review of overlapping meta-analyses regarding MIS versus OS of acute Achilles tendon rupture, aimed to assist decision-makers interpret and choose among conflicting meta-analyses, as well as to offer treatment recommendations based on current best evidence. The literature search was performed to identify systematic reviews comparing MIS with OS for Achilles tendon rupture. Meta-analyses only comprising randomized controlled trials (RCTs) were included. Two authors individually evaluated the quality of meta-analysis and extracted data. The Jadad decision algorithm was conducted to ascertain which meta-analysis offered the best evidence. A total of four meta-analyses was included. All these meta-analyses comprised RCTs or quasi-RCTs and were determined as Level-II evidence. The scores of the Assessment of Multiple Systematic Reviews (AMSTAR) ranged from 7 to 10 (median 9.5). The Jadad algorithm indicated that the best meta-analysis should be chosen according to the search strategies and application of selection. A high-quality meta-analysis with more RCTs was chosen, which suggested that there was no statistically significant difference between MIS and OS regarding rerupture rate, tissue adhesion, sural nerve injury, deep infection, and deep vein thrombosis. However, MIS could decrease superficial infection rate, and had a better patient satisfaction for good to excellent outcomes in comparison to OS. Based on the best available evidence, MIS may be superior to OS for treating acute Achilles tendon rupture. However, due to some limitations, this should be cautiously interpreted, and further high-quality studies are needed.

The aim of this study was to prospectively evaluate the incidence of cardiac rupture during myocardial infarction (MI) as well as the predictive value of the main cardiac rupture risk factors. The study was carried out in 17 coronary care units (CCU) between January and December 1999 in the Piedmont region (Italy). The incidence of cardiac rupture was 1.4% of the total number of MI (n = 3041). Data from 13 out of 17 CCU showed the following causes of death during MI: 66% heart failure, 16% cardiac rupture, 7% arrhythmias, 11% others. Twenty-seven percent out of 44 cardiac ruptures had prior angina, 9% prior MI; 24% of patients were diabetic; 38% had anterior wall MI; 62% infero-postero-lateral MI; 86% showed ST-segment elevation, and 79.5% developed Q waves. Thrombolysis was administered in 39% of cases. Forty-three percent cardiac ruptures occurred within 24 hours. Electromechanical dissociation was present in 73% of cases, syncope and hypotension in 43%, bradycardia in 30%. An echocardiogram was performed in 89% of cases in the suspicion of cardiac rupture but only 45% showed severe pericardial effusion. One patient was referred to surgery but he died in the postoperative period. Autoptical diagnosis was made in 32% of cases. All patients died. The analysis of some qualitative variables (gender, thrombolysis, MI localization, ST-segment/non-ST-segment elevation) in 8 out of 17 CCU, between the cardiac rupture group (n = 22) and the MI group (n = 1330) showed a significant result only for the female gender. Cardiac rupture is the second cause of death during MI after heart failure; there is a higher incidence of cardiac rupture in infero-postero-lateral MI, after the first 24 hours particularly in the female gender; there is a low global incidence (1.4%).

The right median nerve as a peripheral portal to the central nervous system can be electrically stimulated to help coma arousal after traumatic brain injury (TBI). The present study set out to examine the efficacy and safety of right median nerve electrical stimulation (RMNS) in a cohort of 437 comatose patients after severe TBI from August 2005 to December 2011. The patients were enrolled 2 weeks after their injury and assigned to the RMNS group (n=221) receiving electrical stimulation for 2 weeks or the control group (n = 216) treated by standard management according to the date of birth in the month. The baseline data were similar. After the 2-week treatment, the RMNS-treated patients demonstrated a more rapid increase of the mean Glasgow Coma Score, although statistical significance was not reached (8.43 ± 4.98 vs. 7.47 ± 5.37, p = 0.0532). The follow-up data at 6-month post-injury showed a significantly higher proportion of patients who regained consciousness (59.8% vs. 46.2%, p = 0.0073). There was a lower proportion of vegetative persons in the RMNS group than in the control group (17.6% vs. 22.0%, p = 0.0012). For persons regaining consciousness, the functional independence measurement (FIM) score was higher among the RMNS group patients (91.45 ± 8.65 vs. 76.23 ± 11.02, p < 0.001). There were no unique complications associated with the RMNS treatment. The current study, although with some limitations, showed that RMNS may serve as an easy, effective, and noninvasive technique to promote the recovery of traumatic coma in the early phase.

Traumatic rupture of intracardiac structures is an uncommon phenomenon although there are a number of reports with regards to rupture of the tricuspid, mitral and aortic valves. We report the case of a 25-year-old patient who presented with acute aortic and mitral valve regurgitation of traumatic origin. Both lesions were seen separated by 2 weeks. Pathophysiology is reviewed. The combination of both aortic and mitral lesions following blunt chest trauma is almost exceptional.

Emergency department (ED) management of mild traumatic brain injury (TBI) patients with any form of traumatic intracranial hemorrhage (ICH) is variable. Since 2000, our center's standard practice has been to obtain a repeat head computed tomography (CT) at least 6 hours after initial imaging. Patients are eligible for discharge if clinical and CT findings are stable. Whether this practice is safe is unknown. This study characterized clinical outcomes in mild TBI patients with acute traumatic ICH seen on initial ED neuroimaging. This retrospective cohort study included patients presenting to the ED with blunt mild TBI with Glasgow Coma Scale (GCS) scores of 14 or 15 and stable vital signs, during the period from January 2001 to January 2010. Patients with any ICH on initial head CT and repeat head CT within 24 hours were eligible. Cases were excluded for initial GCS < 14, injury > 24 hours old, pregnancy, concomitant nonminor injuries, and coagulopathy. A single investigator abstracted data from records using a standardized case report form and data dictionary. Primary endpoints included death, neurosurgical procedures, and for discharged patients, return to the ED within 7 days. Differences in proportions were computed with 95% confidence intervals (CIs). Of 1,011 patients who presented to the ED and had two head CTs within 24 hours, 323 (32%) met inclusion criteria. The median time between CT scans was 6 hours (interquartile range = 5 to 7 hours). A total of 153 (47%) patients had subarachnoid hemorrhage, 132 (41%) patients had subdural hemorrhage, 11 (3%) patients had epidural hemorrhage, 78 (24%) patients had cerebral contusions, and 59 (18%) patients had intraparenchymal hemorrhage. Four of 323 (1.2%, 95% CI = 0.3% to 3.2%) patients died within 2 weeks of injury. Three of the patients who died had been admitted from the ED on their initial visits, and one had been discharged home. There were 206 patients (64%) discharged from the ED, 28 (13.6%) of whom returned

Acute subdural hematomas (aSDH) secondary to intracranial aneurysm rupture are rare. Most patients present with coma and their functional prognosis has been classically considered to be very poor. Previous studies mixed good-grade and poor-grade patients and reported variable outcomes. We reviewed our experience by focusing on patients in coma only and hypothesized that aSDH might worsen initial mortality but not long-term functional outcome. Between 2005 and 2013, 440 subarachnoid hemorrhage (SAH) patients were admitted to our center. Nineteen (4.3%) were found to have an associated aSDH and 13 (2.9%) of these presented with coma. Their prospectively collected clinical and outcome data were reviewed and compared with that of 104 SAH patients without aSDH who presented with coma during the same period. Median aSDH thickness was 10mm. Four patients presented with an associated aneurysmal cortical laceration and only one had good recovery. Overall, we observed good long-term outcomes in both SAH patients in coma with aSDH and those without aSDH (38.5% versus 26.4%). Associated aSDH does not appear to indicate a poorer long-term functional prognosis in SAH patients presenting with coma. Anisocoria and brain herniation are observed in patients with aSDH thicknesses that are smaller than those observed in trauma patients. Despite a high initial mortality, early surgery to remove the aSDH results in a good outcome in over 60% of survivors. Aneurysmal cortical laceration appears to be an independent entity which shows a poorer prognosis than other types of aneurysmal aSDH. Copyright © 2015 Elsevier Ltd. All rights reserved.

To analyze the short-term prognosis and risk factors of ventricular septal rupture (VSR) following acute myocardial infarction (AMI). A total of 70 consecutive VSR patients following AMI hospitalized in our hospital from January 2002 to October 2010 were enrolled in this study. We compared the clinical characteristics of patients with VSR who survived ≤ 30 days (n = 39) and survived > 30 days (n = 31) post AMI. A short-term prognosis index of VSR (SPIV) was established based on the logistic regression analysis. The single factor analysis showed that the risk factors of death within 30 days of VSR patients were female, anterior AMI, Killip class 3 or 4, apical VSR and non-aneurysm (all P < 0.05). Logistic regression analysis revealed that female (P = 0.013), anterior AMI (P = 0.023), non-aneurysm (P = 0.023), non-diabetes (P = 0.009), Killip class 3 or 4 (P = 0.022) and time from AMI to VSR less than 4 days (P = 0.027) were independent risk determinants for death within 30 days post VSR. Patients with SPIV ≥ 9 were associated with high risk [77.4% (24/31)] of dying within 30 days post AMI. SPIV ≤ 8 were associated with low risk as the 30 days mortality is 28.6% (8/28). Female gender, anterior AMI, non-aneurysm, non-diabetes, Killip class 3 or 4 and time from AMI to VSR less than 4 days are independent risk factors of short-term mortality of VSR.

Since the introduction of reperfusion in the treatment of acute myocardial infarction (AMI), rates of ventricular septal rupture (VSR) and associated mortality have decreased, but it is not known if incidence and mortality have continued to decrease. We describe trends in incidence and mortality rates of patients with postinfarction VSR during the previous 2 decades and identify risk factors that predict the development and mortality of this rare but catastrophic complication. We analyzed occurrence and mortality rates in patients with first AMI with (n = 408) and without VSR (n = 148,473) who were hospitalized from 1990 to 2007 using the New Jersey Myocardial Infarction Data Acquisition System (MIDAS) database. The annual rate of VSR in AMI was 0.25% to 0.31%. Compared to patients with AMI without VSR, patients with VSR were older, more likely to be women, had increased rate of chronic renal disease, congestive heart failure, and cardiogenic shock, and were less likely to be hypertensive or diabetic (all p values < 0.0001). During the 18-year study period, we found no change in hospital and 1-year mortalities, which were 41% and 60% in 1990 to 1992 and 44% and 56% in 2005 to 2007, respectively. The survival benefit associated with VSR surgical repair was seen only in hospital (hazard ratio 0.66, 95% confidence interval 0.45 to 0.95) but not at 30 days or 1 year. In conclusion, despite improvement in medical treatment and revascularization techniques, the rate of VSR complicating AMI has not changed during the previous 2 decades, and the mortality associated with VSR has remained high and relatively constant.

This study was designed to (i) evaluate the influence of age on diffusion tensor imaging measures of white matter assessed using tract-based spatial statistics; (ii) determine if mild traumatic brain injury is associated with microstructural changes in white matter, in the acute phase following injury, in a large homogenous sample that was carefully screened for pre-injury medical, psychiatric, or neurological problems; and (iii) examine if injury severity is related to white matter changes. Participants were 75 patients with acute mild traumatic brain injury (age = 37.2 ± 12.0 years, 45 males and 30 females) and 40 controls (age = 40.6 ± 12.2 yrs, 20 males and 20 females). Age effects were analysed by comparing control subgroups aged 31-40, 41-50, and 51-60 years against a group of 18-30-year-old control subjects. Widespread statistically significant areas of abnormal diffusion tensor measures were observed in older groups. Patients and controls were compared using age and gender as covariates and in age- and gender-matched subgroups. Subgroups of patients with more severe injuries were compared to age-and gender-matched controls. No significant differences were detected in patient-control or severity analyses (all P-value > 0.01). In this large, carefully screened sample, acute mild traumatic brain injury was not associated with diffusion tensor imaging abnormalities detectable with tract-based spatial statistics.

We describe an unusual presentation of a ruptured aneurysm of the posterior communicating artery with an acute intracranial hematoma between the dural layers associated with an acute spinal epidural hematoma descending to L1. A 35-year-old woman presented 3 hours after ictus with a postcoital headache, neck stiffness, and bilateral abducens cranial nerve palsy. No other neurological deficits were present. Clinically, she had a subarachnoid hemorrhage World Federation of Neurosurgical Societies grade 1. CT scan demonstrates an acute subdural hematoma, extending from the right parasellar region, around the clivus, tentorium, and falx. Angio-CT showed a posterior communicating artery aneurysm and an anterior communicating artery aneurysm and an extension of the hematoma to the cervical spine. This justified a spinal and cerebral MRI that confirmed an extension of the hematoma to the epidural space at the cervical, thoracic, and lumbar levels. Three-dimensional digital subtraction angiography confirmed aneurysms on the right posterior communicating artery and on the anterior communicating artery. Both aneurysms were completely occluded by coiling. With reference to the concept of the cranial subdural compartment described in studies conducted using an electron microscope, this group of hematomas was classified as interdural. Ruptured aneurysm of the posterior communicating artery may cause cranial acute interdural hematoma with a typical subarachnoid hemorrhage clinical presentation, and it rarely can extend to spinal epidural space.

Acute scrotum constitutes the most common urological emergency secondary to spermatic cord torsion, testicular trauma, orchiepididymitis and hernias. We report a very rare case of unique traumatic spermatic cord hematoma following scrotum injury occurred during a football match. Clinical exam showed an increased volume of the left spermatic cord; the color Doppler ultrasound (CDU) demonstrated left testicular ischemia secondary to a large spermatic cord hematoma that needs surgical exploration. Spermatic cord hematoma rarely induces acute scrotum, however it could be treated conservatively surgery is mandatory when pain is persistent or testicular ischemia is confirmed by CDU. PMID:26793493

We present a clinical case of a 52-year-old man with bilateral traumatic rupture of the Achilles tendon (AT) in absence of risk factors. In medical history, the patient does not report pre-existing tendon diseases. AT ruptures occurred following a skiing injury in which the forward fall caused a severe stress and elongation of the AT. Associated with tendon injury there was a fracture of the right humeral greater tuberosity. The patient was subjected to percutaneous tenorraphy according to Maffulli's technique and subsequently topical injection of autologous platelet-rich plasma (PRP) 7 days after the injury. After surgery, the patient followed an accelerated rehabilitation protocol, allowing the weight bearing with guards (Rom-Walker) and crutches to four weeks then freely to 8 weeks. We performed a clinical (AOFAS ankle-hindfoot score) and ultrasonography follow-up at month 1, 3, 6 and 12, with excellent results in the end. To the best of our knowledge bilateral cases like this have not been described in the literature.
Background Magnetic resonance (MR) imaging is the preferred diagnostic tool to evaluate internal disorders of many joints in humans; however, the usefulness of MR imaging in the context of osteoarthritis, and joint disease in general, has yet to be characterized in veterinary medicine. The objective of this study was to assess the diagnostic accuracy of short-duration 3 Tesla MR imaging for the evaluation of cranial and caudal cruciate ligament, meniscal and cartilage damage, as well as the degree of osteoarthritis, in dogs affected by non-traumatic, naturally-occurring cranial cruciate ligament rupture (CCLR). Diagnoses made from MR images were compared to those made during surgical exploration. Twenty-one client-owned dogs were included in this study, and one experienced evaluator assessed all images. Results All cranial cruciate ligaments were correctly identified as ruptured. With one exception, all caudal cruciate ligaments were correctly identified as intact. High sensitivities and specificities were obtained when diagnosing meniscal rupture. MR images revealed additional subclinical lesions in both the cranial and caudal cruciate ligaments and in the menisci. There was a “clear” statistical (kappa) agreement between the MR and the surgical findings for both cartilage damage and degree of osteoarthritis. However, the large 95% confidence intervals indicated that evaluation of cartilage damage and of degree of osteoarthritis is not clinically satisfactory. Conclusions The presence of cruciate ligament damage and meniscal tears could be accurately assessed using the MR images obtained with our protocol. However, in the case of meniscal evaluation, occasional misdiagnosis did occur. The presence of cartilage damage and the degree of osteoarthritis could not be properly evaluated. PMID:23448526

The present report describes an acute subdural hematoma (ASDH) associated with subarachnoid hemorrhage (SAH), due to ruptured cortical aneurysm. To our knowledge, extremely rare cases of this sort have been reported so far. A 23-year-old male patient without previous trauma presented with severe headache and rapidly decreasing level of consciousness to decerebrate status. Computed tomography (CT) scan has demonstrated an ASDH together with SAH. Hematoma has immediately been evacuated without any evaluation by angiography. After evacuation of the thick subdural clot, a 10-mm aneurysm was revealed on a precentral artery of frontal cortex, which was ligated. However, after 35 days the patient discharged with left side hemiparesis and dysphasia, and just after several months of admission he got symptom free. Ruptured cortical aneurysm should be considered as one of the causes of spontaneous ASDH. Vascular anomaly investigations are suggested for these cases, thus CT angiography or digital subtraction angiography has to be considered if clinical condition allows. PMID:28503501

Aim: The aim of this study was to investigate a relationship between seasonal variation and incidence of type A acute aortic dissection (AAD) and spontaneous abdominal aneurysm rupture (rAAA) in Canton Tuzla, Bosnia and Herzegovina. Patients and methods: A total of 81 cases, 41 AAD and 40 of ruptured AAA were identified from one center over a 6-year, from 2008 till 2013. In 2012 were admitted (45.6% or 36 patients). Results: Seasonal analysis showed that 19(23.4%) patients were admitted in spring, 15(18.5) in summer, 26(32%) in autumn and 21(25.9) in winter. The most frequent period was autumn/winter with 47 or 58% patients. A causal link between atmospheric pressure (AP) and incidence of rAAA and AAD on seasonal and monthly basis was found.

To study gastric rupture, a progressive, rapid and high mortality condition, caused by acute gastric distention (GRAGD) and its appropriate diagnosis and treatment. The etiology, pathology, clinical manifestations and experiences in 3 children with GRAGD were reviewed. Case 1: After diagnosing GRAGD and stabilizing her shock with massive fluid replacement, gastrostomy was performed. Her postoperative course was uneventful because of fasting, suction, fluid infusion, correction of acidosis and supporting nutrition. Case 2: After diagnosing gastric distention which subsided with conservative therapy for 9 days, she suddenly had gastric rupture when she had not eaten for 6 days. She died of shock and had no chance for surgery. Case 3: The patient had sudden abdominal pain, distention and vomiting with severe shock for 4 days. Emergency surgery found gastric rupture and the method was the same as Case 1. The patient survived but has brain impairment. Case 1 and 3 showed multifocal transmural necrosis. Symptoms like overeating, bulimia, changes in kind of food, X-ray showing large distended stomach and massive pneumoperitoneum were seen after gastric rupture and can help to diagnose this condition. Clinical course of gastric distention with toxic shock progresses rapidly, however subsequent gastric rupture exacerbates the shock and makes the treatment difficult treatment. It is extremely important that a laparotomy be performed at once after stabilizing shock with massive fluid replacement. Postoperative nutritional support and fluid replacement will increase survival. It is very important that when gastric distention disappears after conservative therapy, the doctor should assess carefully whether the gastric wall recovery is under way by using effective methods of examination.

To describe institutional variation in traumatic brain injury (TBI) inpatient rehabilitation program characteristics and evaluate to what extent patient factors and center effects explain how TBI inpatient rehabilitation services are delivered. Secondary analysis of a prospective, multicenter, cohort database. TBI inpatient rehabilitation programs. Patients with complicated mild, moderate, or severe TBI (N=2130). Not applicable. Mean minutes; number of treatment activities; use of groups in occupational therapy, physical therapy, speech therapy, therapeutic recreation, and psychology inpatient rehabilitation sessions; and weekly hours of treatment. A wide variation was observed between the 10 TBI programs, including census size, referral flow, payer mix, number of dedicated beds, clinician experience, and patient characteristics. At the centers with the longest weekday therapy sessions, the average session durations were 41.5 to 52.2 minutes. At centers with the shortest weekday sessions, the average session durations were approximately 30 minutes. The centers with the highest mean total weekday hours of occupational, physical, and speech therapies delivered twice as much therapy as the lowest center. Ordinary least-squares regression modeling found that center effects explained substantially more variance than patient factors for duration of therapy sessions, number of activities administered per session, use of group therapy, and amount of psychological services provided. This study provides preliminary evidence that there is significant institutional variation in rehabilitation practice and that center effects play a stronger role than patient factors in determining how TBI inpatient rehabilitation is delivered.

Traumatic brain injury (TBI) leads to nearly 300 000 annual US hospitalizations and increased lifetime risk of acute ischemic stroke (AIS). Occurrence of AIS immediately after TBI has not been well characterized. We evaluated AIS acutely after TBI and its impact on outcome. A prospective database of moderate to severe TBI survivors, admitted to inpatient rehabilitation at 22 Traumatic Brain Injury Model Systems centers and their referring acute-care hospitals, was analyzed. Outcome measures were AIS incidence, duration of posttraumatic amnesia, Functional Independence Measure, and Disability Rating Scale, at rehabilitation discharge. Between October 1, 2007, and March 31, 2015, 6488 patients with TBI were enrolled in the Traumatic Brain Injury Model Systems National Database. One hundred and fifty-nine (2.5%) patients had a concurrent AIS, and among these, median age was 40 years. AIS was associated with intracranial mass effect and carotid or vertebral artery dissection. High-velocity events more commonly caused TBI with dissection. AIS predicted poorer outcome by all measures, accounting for a 13.3-point reduction in Functional Independence Measure total score (95% confidence interval, -16.8 to -9.7; P<0.001), a 1.9-point increase in Disability Rating Scale (95% confidence interval, 1.3-2.5; P<0.001), and an 18.3-day increase in posttraumatic amnesia duration (95% confidence interval, 13.1-23.4; P<0.001). Ischemic stroke is observed acutely in 2.5% of moderate to severe TBI survivors and predicts worse functional and cognitive outcome. Half of TBI patients with AIS were aged ≤40 years, and AIS patients more often had cervical dissection. Vigilance for AIS is warranted acutely after TBI, particularly after high-velocity events. © 2017 American Heart Association, Inc.

We determine the diagnostic performance of emergent orbital computed tomography (CT) scans for assessing globe rupture in patients with blunt facial trauma. We performed a retrospective cohort study based on prospectively collected trauma registry and acute care surveillance data in a tertiary-care hospital. Patients aged at least 18 years who underwent isolated orbital CT scanning for assessing potential ocular trauma were examined. Analyses were performed to evaluate the magnitude of agreement between diagnosis by CT scanning and ophthalmic assessment, including globe rupture. Our study cohort comprised 136 patients, 30% of whom (41 patients) sustained orbital wall fractures. Concordance for orbital CT diagnosis and the ophthalmic assessment of globe rupture was substantial (k=0.708). The relative risk of globe rupture was 0.692 (95% confidence interval (CI): 0.054-8.849) for superior wall fractures, 0.459 (95% CI: 0.152-1.389) for inferior wall fractures, 2.286 (95% CI: 1.062-4.919) for lateral wall fractures, and 0.637 (95% CI: 0.215-1.886) for medial wall fractures. According to multivariate analysis, lateral wall fractures were an independent risk factor for globe ruptures (adjusted odds ratio (OR)=12.01, P=0.011), and medial or inferior wall fracture was a protective factor (adjusted OR=0.14, P=0.012). In the stratified analysis of diagnostic performance of CT scan, specificity was highest among patients with orbital wall fractures (97.2%), followed by negative predictive volume (NPV, 97%), and accuracy (95.1%). Among patients with blunt facial trauma who underwent isolated orbital CT scanning as part of ocular trauma assessment, the diagnostic performance of CT in detecting globe rupture is more accurate in patients with orbital wall fractures. Nevertheless, isolated orbital CT alone does not have a sufficiently high diagnostic performance to be reliable to rule out all globe ruptures. Lateral orbital wall fractures in blunt facial trauma patients, in

Decompressive craniectomy (DC) is a life-saving measure for traumatic brain injury (TBI), but acute seizures following this procedure may have a devastating effect. We aim to investigate the clinical characteristics of acute post-craniectomy seizures. For this retrospective study, we enrolled 195 patients undergoing DC for TBI. Acute post-craniectomy seizure was defined as seizures occurring within 7 days of DC. The incidence of acute seizure was 10.8% (21/195). 19 of 21 seizures occurred within 3 days following DC. None progressed to status epilepticus, but 16 of 21 patients (76.2%) with acute seizure developed epilepsy. There was no independent risk factor in the multivariate regression model. The mean hospital stay was 44.8 ± 34.6 and 28.8 ± 32.3 days for patients with and without acute seizures, respectively (p=0.035). The neurological outcome at discharge showed no inter-group difference (p=0.917). The in-hospital mortality rate was 28.6% for patients with seizures and 31.0% for patients without seizures (p=0.817). Acute seizures occur mostly within the first 3 days following DC. Neurological outcome and mortality rate at discharge does not differ between patients with or without seizures, but the duration of hospital stay is significantly longer for acute seizure patients.

A novel technique for managing ruptured tibialis anterior tendon complicated by infection and tendon substance loss in a young adult is described. A two-stage reconstruction technique with a silicon tube and tendon autograft was performed. At first, after local control of the infection, scar excision and placement of a silicone tube was performed. Ten weeks later, ipsilateral hamstrings tendons were harvested and bridged the 7 cm tendon gap. Eighteen months later, the patient has excellent clinical and functional outcome.

Acute traumatic coagulopathy (ATC) has been reported in the setting of isolated traumatic brain injury (iTBI) and associated with high mortality and poor outcomes. The aim of this systematic review was to examine the incidence and outcome of patients with ATC in the setting of iTBI. We conducted a search of the MEDLINE database and Cochrane library, focused on subject headings and keywords involving coagulopathy and TBI. Design and results of each study were described. Studies were assessed for heterogeneity and the pooled incidence of ATC in the setting of iTBI determined. Reported outcomes were described. There were 22 studies selected for analysis. A statistically significant heterogeneity among the studies was observed (p<0.01). Using the random effects model the pooled proportion of patients with ATC in the setting of iTBI was 35.2% (95% CI: 29.0-41.4). Mortality of patients with ATC and iTBI ranged between 17% and 86%. Higher blood transfusion rates, longer hospital stays, longer ICU stays, decreased ventilator free days, higher rates of single and multiple organ failure and higher incidence of delayed injury and disability at discharge were reported among patients with ATC. ATC is commonly associated with iTBI and almost uniformly associated with worse outcomes. Any disorder of coagulation above the normal range appears to be associated with worse outcomes and therefore a clinically important target for management. Earlier identification of patients with ATC and iTBI, for recruitment into prospective trials, presents avenues for further research. Copyright © 2014 Elsevier Ltd. All rights reserved.

Brain edema is a significant challenge facing clinicians managing severe traumatic brain injury (TBI) in the acute period. If edema reaches a critical point, it leads to runaway intracranial hypertension that, in turn, leads to severe morbidity or death if left untreated. Clinical data on the efficacy of standard interventions is mixed. The goal of this study was to validate a novel therapeutic strategy for reducing post-traumatic brain edema in a mouse model. Prior in vitro work reported that the brain swells due to coupled electrostatic and osmotic forces generated by large, negatively charged, immobile molecules in the matrix that comprises brain tissue. Chondroitinase ABC (ChABC) digests chondroitin sulfate proteoglycan, a molecule that contributes to this negative charge. Therefore, we administered ChABC by intracerebroventricular (ICV) injection after controlled cortical impact TBI in the mouse and measured associated changes in edema. Almost half of the edema induced by injury was eliminated by ChABC treatment. ICV administration of ChABC may be a novel and effective method of treating post-traumatic brain edema in the acute period.

The degree of post-traumatic brain edema and dysfunction of the blood-brain barrier (BBB) influences the neurofunctional outcome after a traumatic brain injury (TBI). Previous studies have demonstrated that the administration of apolipoprotein E-mimetic peptide COG1410 reduces the brain water content after subarachnoid hemorrhage, intra-cerebral hemorrhage, and focal brain ischemia. However, the effects of COG1410 on vasogenic edema following TBI are not known. The current study evaluated the effects of 1 mg/kg daily COG1410 versus saline administered intravenously after a controlled cortical impact (CCI) injury on BBB dysfunction and vasogenic edema at an acute stage in mice. The results demonstrated that treatment with COG1410 suppressed the activity of matrix metalloproteinase-9, reduced the disruption of the BBB and Evans Blue dye extravasation, reduced the TBI lesion volume and vasogenic edema, and decreased the functional deficits compared with mice treated with vehicle, at an acute stage after CCI. These findings suggest that COG1410 is a promising preclinical therapeutic agent for the treatment of traumatic brain injury.

Traumatic brain injury (TBI) has been known to be the leading cause of breakdown and long-term disability in people under 45 years of age. This study highlights the effective factors on post-traumatic (PT) linguistic disorder and relations between linguistic and cognitive function after trauma in adults with acute TBI. A cross-sectional design was employed to study 60 post-TBI hospitalized adults aged 18-65 years. Post-traumatic (PT) linguistic disorder and cognitive deficit after TBI were respectively diagnosed using the Persian Aphasia Test (PAT) and Persian version of Mini-Mental State Examination (MMSE) at discharge. Primary post-resuscitation consciousness level was determined using the Glasgow Coma Scale (GCS). Paracilinical data was obtained by CT scan technique. Multiple logistic regression analysis illustrated that brain injury severity was the first powerful significant predictor of PT linguistic disorder after TBI and frontotemporal lesion was the second. It was also revealed that cognitive function score was significantly correlated with score of each language skill except repetition. Subsequences of TBI are more commonly language dysfunctions that demand cognitive flexibility. Moderate, severe and fronto-temporal lesion can increase the risk of processing deficit in linguistic macrostructure production and comprehension. The dissociation risk of cortical and subcortical pathways related to cognitive-linguistic processing due to intracranial lesions can augment possibility of lexical-semantic processing deficit in acute phase which probably contributes to later cognitive-communication disorder.

Surgical repair is a common method of treatment of acute Achilles rupture in North America because, despite a higher risk of overall complications, it has been believed to offer a reduced risk of rerupture. However, more recent trials, particularly those using functional bracing with early range of motion, have challenged this belief. The aim of this meta-analysis was to compare surgical treatment and conservative treatment with regard to the rerupture rate, the overall rate of other complications, return to work, calf circumference, and functional outcomes, as well as to examine the effects of early range of motion on the rerupture rate. A literature search, data extraction, and quality assessment were conducted by two independent reviewers. Publication bias was assessed with use of the Egger and Begg tests. Heterogeneity was assessed with use of the I2 test, and fixed or random-effect models were used accordingly. Pooled results were expressed as risk ratios, risk differences, and weighted or standardized mean differences, as appropriate. Meta-regression was employed to identify causes of heterogeneity. Subgroup analysis was performed to assess the effect of early range of motion. Ten studies met the inclusion criteria. If functional rehabilitation with early range of motion was employed, rerupture rates were equal for surgical and nonsurgical patients (risk difference = 1.7%, p = 0.45). If such early range of motion was not employed, the absolute risk reduction achieved by surgery was 8.8% (p = 0.001 in favor of surgery). Surgery was associated with an absolute risk increase of 15.8% (p = 0.016 in favor of nonoperative management) for complications other than rerupture. Surgical patients returned to work 19.16 days sooner (p = 0.0014). There was no significant difference between the two treatments with regard to calf circumference (p = 0.357), strength (p = 0.806), or functional outcomes (p = 0.226). The results of the meta-analysis demonstrate that conservative

Acute Achilles tendon ruptures is one of the commonest tendon injury of the foot and ankle. The management of this problem is still controversial. Treatment can be classified into non-surgical and surgical types. Surgical management can be subdivided into open repair, percutaneous with or without adjunct of arthroscopy. In compare with non-surgical management, surgical management will decrease the tendon re-rupture rate. However, the possible surgical complications including wound breakdown and sural nerve injury are still quite significant. Percutaneous repair technique has the advantage of less chance of wound breakdown, but the rate of tendon re-rupture is higher than that after open tendon repair, because the repair is usually weaker than that achieved in open repair. Lui have described an endoscopic assisted repair with the Krackow locking suture. However, the technique is complicated and six portal wounds are needed. A simpler way of applying the Krackow suture through the portal wound has been described for reattachment of Achilles tendon insertion after endoscopic calcaneoplasty. We describe a mini-open approach of Achilles tendon repair with the Krackow locking suture. By means of release of the medial edge of the investing fascia, the Achilles tendon can be mobilized easily and the Krackow locking suture can be applied through a 1.5cm medial wound. Hopefully, this can improve the strength of repair and maintaining the advantage of minimally invasive tendon repair.

We compared the cardiac output measured by the transpulmonary aortic single indicator thermodilution method with that by the pulmonary artery catheterization in a patient with ventricular septal rupture after acute myocardial infarction. Though the former cardiac output was lower than the latter, in the presence of the ventricular septal rupture, the cardiac outputs were equal after the rupture was closed. This indicates that, while the cardiac output measured by the pulmonary artery catheter is influenced by the ventricular left-to-right shunt, transpulmonary aortic thermodilution method measures the true cardiac output of the left heart, which is responsible for organ perfusion.

Introduction Rupture of the diaphragm is almost always due to major trauma. Diaphragmatic injuries are rare (5–7%), usually secondary to blunt, or more rarely to penetrating, thoracic or abdominal trauma. No single investigation provides a reliable diagnosis of diaphragmatic rupture when a patient first arrives at hospital. Almost 33% are suspected on initial chest x-ray, but the percentage is lower in patients who are immediately intubated. Mortality in patients with diaphragmatic rupture following blunt abdominal trauma is generally associated with coexistent vascular and visceral injuries that could be rapidly fatal. It's mandatory that the right diagnosis is reached as soon as possible given that mortality is influenced by the time elapsing between trauma and diagnosis. Case presentation A 35-year-old worker was hit by a heavy object while working in the factory. He was transferred immediately to our emergency room. Chest x-ray showed massive left hemothorax without any additional signs to suggest diaphragmatic injury. It was decided to perform immediate surgical exploration before further radiological examination. During surgery, the right kidney and liver appeared normal, but the left kidney and spleen were not found in their anatomical position. The left hemidiaphragm had a10-cm oblique posterior tear. The left kidney was found lacerated in the left side of the chest, separated completely from its vascular pedicle and ureter, along with the entire spleen which was also separated from its vascular tree. Conclusion The avulsion of both kidney and spleen following abdominal trauma is uncommon and survival depends on prompt diagnosis and treatment. PMID:18076752

Background Apart from the severity of myocardial infarction and coronary artery disease, several predictors of in-hospital death (In-HD) are suggested in patients with acute myocardial infarction (AMI). Methods We investigated predictors of In-HD and ventricular rupture (VR) including ventricular septal rupture (VSR) and free wall rupture (FWR) with stepwise multivariable logistic regressions in 1,042 patients admitted to our Cardiovascular Center within 48 hours from symptom onset for the first attack of AMI. Results In-HD, VSR, and FWR were observed in 78 cases (7.5%), 14 cases of which 13 cases were In-HD, and 13 cases of which 6 cases were In-HD, respectively. Apart from the disease severity, age and renal dysfunction (RD) defined by estimated glomerular filtration rate of lower than 60 mL/min/ 1.73 m2 were independent positive predictors of In-HD (the odds ratios (ORs) (95% confidence interval (CI)): 1.04 (1.01 - 1.06) P = 0.0069 and 5.75 (3.12 - 10.59) P < 0.0001, respectively) and hypercholesterolemia was an independent negative predictor for In-HD (OR (95% CI): 0.34 (0.17 - 0.67) P = 0.0017). After including the categories of coronary disease, ventricular rupture, and ejection fraction in predictors, RD remained an independent predictor of In-HD (OR (95% CI): 6.65 (2.67 - 16.60) P < 0.0001). Age (OR (95% CI): 1.07 (1.02 - 1.12) P = 0.0064), RD (OR (95% CI): 2.77 (1.18 - 6.49) P = 0.019), and diabetes (OR (95% CI): 2.52 (1.12 - 5.71) P = 0.026) were independent predictors of VR. Conclusions RD was an independent predictor of In-HD and VR in patients with initial AMI.

A 65-year-old male was brought to our hospital with right upper abdominal fullness sensation and recent body weight loss of about 3 kg. The patient had developed episodes of melena following progressive abdominal muscular guarding and drop of haemoglobin level to 6.3 g/dL. An abdominal computed tomography scan disclosed a ruptured hepatocellular cell carcinoma. A segmental arterial mediolysis was found on the superior mesenteric artery in the process of repairing the ruptured right hepatic artery with the assistance of angiography. Transarterial embolization was carried out and permanent haemostasis was achieved.

Background Spontaneous rupture of the spleen is an uncommon dramatic abdominal emergency that requires immediate diagnosis and prompt surgical treatment to ensure the patients survival. Infections have been cited in most cases involving splenic rupture but are rare in hematological malignancies despite frequent involvement of the spleen. Methods and Materials We present a case of a splenic rupture caused by infiltration of B-cell lymphoma. A 43 year old gentleman presented with a 1 day h/o left upper quadrant pain; nausea and vomiting for 2 days with associated dizziness and anorexia. The CT showed abnormal spleen 20 × 11 cm with free fluid in the abdomen and enlarged retroperitoneal LNs. The patient underwent a splenectomy after initial resuscitation and the operative finding was that of a massively enlarged spleen with areas of tumor extruding through the splenic capsule. Result and conclusion Although the spleen is often involved in hematological malignancies, splenic rupture is an infrequent occurrence. In a recent literature review 136 cases were of splenic rupture secondary to hematological malignancy were identified. Acute leukemia and non Hodgkin lymphoma were the frequent causes followed by chronic myelogeneous leukemia. Male sex, adulthood, severe splenomegaly and cytoreductive chemotherapy were factors more often associated with splenic rupture. Emergency splenectomy remains the cornerstone treatment for splenic rupture. We present a case report of a "spontaneous splenic rupture" and discuss the presentation, etiology and treatment options along with discussion of relevant literature PMID:17129392

Tricuspid insufficiency due to penetrating cardiac trauma is rare. Patients with tricuspid insufficiency due to trauma can tolerate this abnormality for months or even years. We report a case of a 66-year-old female with penetrating cardiac trauma on the right side of her heart that required tricuspid valve repair in an acute setting. She sustained cut and stab wounds on her bilateral forearms and in the neck and epigastric region. She had cardiac tamponade and developed pulseless electrical activity, which required emergency surgery. The right ventricle and superior vena cava were dissected approximately 5 cm and 2 cm, respectively. After these wounds had been repaired, the patient's inability to wean from cardiopulmonary bypass suggested rightsided heart failure; transesophageal echocardiography revealed tricuspid insufficiency. Right atriotomy was performed, and a detailed examination revealed that the tricuspid valve septal leaflet was split in two. There was also an atrial septal injury that created a connection with the left atrium; these injuries were not detected from the right ventricular wound. After repair, weaning from cardiopulmonary bypass with mild tricuspid insufficiency was achieved, and she recovered uneventfully. This case emphasized the importance of thoroughly investigating intracardiac injury and transesophageal echocardiography.

This study looked at performance on the conversational discourse checklist of the Protocole Montréal d'évaluation de la communication (D-MEC) in 195 adults with TBI of all severity hospitalized in a Level 1 Trauma Centre. To explore validity, results were compared to findings on tests of memory, mental flexibility, confrontation naming, semantic and letter category naming, verbal reasoning, and to scores on the Montreal Cognitive Assessment. The relationship to outcome as measured with the Disability Rating Scale (DRS), the Extended Glasgow Outcome Scale (GOS-E), length of stay, and discharge destinations was also determined. Patients with severe TBI performed significantly worse than mild and moderate groups (χ(2)(KW2df) = 24.435, p = .0001). The total D-MEC score correlated significantly with all cognitive and language measures (p < .05). It also had a significant moderate correlation with the DRS total score (r = -.6090, p < .0001) and the GOS-E score (r = .539, p < .0001), indicating that better performance on conversational discourse was associated with a lower disability rating and better global outcome. Finally, the total D-MEC score was significantly different between the discharge destination groups (F(3,90) = 20.19, p < .0001). Thus, early identification of conversational discourse impairment in acute care post-TBI was possible with the D-MEC and could allow for early intervention in speech-language pathology.

To date, studies directly comparing the rerupture rate in patients with an Achilles tendon rupture who are treated with surgical repair with the rate in patients treated nonoperatively have been inconclusive but the pooled relative risk of rerupture favored surgical repair. In all but one study, the limb was immobilized for six to eight weeks. Published studies of animals and humans have shown a benefit of early functional stimulus to healing tendons. The purpose of the present study was to compare the outcomes of patients with an acute Achilles tendon rupture treated with operative repair and accelerated functional rehabilitation with the outcomes of similar patients treated with accelerated functional rehabilitation alone. Patients were randomized to operative or nonoperative treatment for acute Achilles tendon rupture. All patients underwent an accelerated rehabilitation protocol that featured early weight-bearing and early range of motion. The primary outcome was the rerupture rate as demonstrated by a positive Thompson squeeze test, the presence of a palpable gap, and loss of plantar flexion strength. Secondary outcomes included isokinetic strength, the Leppilahti score, range of motion, and calf circumference measured at three, six, twelve, and twenty-four months after injury. A total of 144 patients (seventy-two treated operatively and seventy-two treated nonoperatively) were randomized. There were 118 males and twenty-six females, and the mean age (and standard deviation) was 40.4 ± 8.8 years. Rerupture occurred in two patients in the operative group and in three patients in the nonoperative group. There was no clinically important difference between groups with regard to strength, range of motion, calf circumference, or Leppilahti score. There were thirteen complications in the operative group and six in the nonoperative group, with the main difference being the greater number of soft-tissue-related complications in the operative group.

The optimal treatment for acute Achilles tendon ruptures is still a subject of debate. Early loading of the tendon is a factor that has been shown to be beneficial to recovery and to minimize complications. The main outcome of previous studies has been complications such as reruptures and deep infections, without focusing on the functional outcome relevant to the majority of patients who do not experience these complications. To evaluate whether stable surgical repair and early loading of the tendon could improve patient-reported outcome and function after an acute Achilles tendon rupture. Randomized controlled trial; Level of evidence, 1. A total of 100 patients (86 men, 14 women; mean age, 40 years) with an acute total Achilles tendon rupture were randomized to either surgical treatment, including an accelerated rehabilitation protocol, or nonsurgical treatment. The primary outcome was the Achilles tendon Total Rupture Score (ATRS). The patients were evaluated at 3, 6, and 12 months for symptoms, physical activity level, and function. There were no significant differences between the groups in terms of symptoms, physical activity level, or quality of life. There was a trend toward improved function in surgically treated patients; the results were significantly superior when assessed by the drop countermovement jump (95% CI, 0.03-0.15; P = .003) and hopping (95% CI, 0.01-0.33; P = .040). No reruptures occurred in the surgical group, while there were 5 in the nonsurgical group (P = .06). There were 6 superficial infections in the surgically treated group; however, these superficial infections had no bearing on the final outcome. Symptoms, reduced quality of life, and functional deficits still existed 12 months after injury on the injured side in both groups. The results of the present study demonstrate that stable surgical repair with accelerated tendon loading could be performed in all (n = 49) patients without reruptures and major soft tissue

The review outlines recent clinical and experimental studies regarding the effects of red blood-cell transfusion on clinical outcome in neurocritical patients, including patients with subarachnoid hemorrhage, acute ischemic stroke and traumatic brain injury. Optimal hemoglobin transfusion trigger and the role of other transfusion indicators for neurocritical patients are discussed. Acute anemia (hemoglobin levels near 7 g/dl) is well tolerated by healthy subjects, but extreme anemia might negatively affect clinical outcome of neurocritical patients. Conversely, high hemoglobin levels, attained by means other than red blood-cell transfusion, improve clinical outcome, whereas red blood-cell transfusion is associated with poorer clinical outcome (mortality, length of stay and disability) in patients presenting subarachnoid hemorrhage, acute ischemic stroke and traumatic brain injury. Studies defining the optimal hemoglobin concentration in neurocritical patients are lacking, but a restrictive transfusion policy seems to be safe and is often recommended. In the near future, signals coming from the brain, such as brain tissue oxygen tension and regional cerebral oxygen saturation, might potentially be developed into transfusion triggers. Both severe anemia and red blood-cell transfusion may negatively influence clinical outcome in neurocritical patients. Acceptance of low hemoglobin concentrations may be justified by avoiding negative transfusion effects. No evidence-based transfusion trigger in neurocritical patients can be recommended.

"Acute abdomen" includes spectrum of medical and surgical conditions ranging from a less severe to life-threatening conditions in a patient presenting with severe abdominal pain that develops over a period of hours. Accurate and rapid diagnosis of these conditions helps in reducing related complications. Clinical assessment is often difficult due to availability of over-the-counter analgesics, leading to less specific physical findings. The key clinical decision is to determine whether surgical intervention is required. Laboratory and conventional radiographic findings are often non-specific. Thus, cross-sectional imaging plays a pivotal role for helping direct management of acute abdomen. Computed tomography is the primary imaging modality used for these cases due to fast image acquisition, although US is more specific for conditions such as acute cholecystitis. Magnetic resonance imaging or ultrasound is very helpful in patients who are particularly sensitive to radiation exposure, such as pregnant women and pediatric patients. In addition, MRI is an excellent problem-solving modality in certain conditions such as assessment for choledocholithiasis in patients with right upper quadrant pain. In this review, we discuss a multimodality approach for the usual causes of non-traumatic acute abdomen including acute appendicitis, diverticulitis, cholecystitis, and small bowel obstruction. A brief review of other relatively less frequent but important causes of acute abdomen, such as perforated viscus and bowel ischemia, is also included.

The effect of experimental acute hyponatraemia on severe traumatic brain injury (TBI) was studied in a modified impact-acceleration model. The cortical contusional volume was quantified by image analysis on serial sections, injured axons were visualized and quantified by beta-Amyloid Precursor Protein (beta-APP) immunohistochemical staining. Regional brain water content was estimated by the wet-dry weight method. The experiment was conducted in Group I (injury only) and Group II (injury followed by acute hyponatraemia). Comparison between the two groups showed that acute hyponatraemia significantly increased contusional volume (3.24 +/- 0.70 mm3 vs. 1.80 +/- 0.65 mm3, P = 0.009) and the number of injured axons (128.7 +/- 44.3 vs. 41.7 +/- 50.1, P = 0.04) in the right thalamus & basal ganglia region. Water content of the brain stem region was also significantly increased by acute hyponatraemia (73.71 +/- 0.14% vs. 72.28 +/- 0.93%, P = 0.004). These results suggest that acute hyponatraemia potentiates secondary brain damage in severe TBI by augmentation of both focal contusion and diffuse axonal injury. The injured brain stem region is more susceptible to edema formation induced by experimental acute hyponatraemia.

OBJECTIVE: To quantify the effectiveness and safety of corticosteroids in the treatment of acute traumatic brain injury. DESIGN: Systematic review of randomised controlled trials of corticosteroids in acute traumatic brain injury. Summary odds ratios were estimated as an inverse variance weighted average of the odds ratios for each study. SETTING: Randomised trials available by March 1996. SUBJECTS: The included trials with outcome data comprised 2073 randomised participants. RESULTS: The effect of corticosteroids on the risk of death was reported in 13 included trials. The pooled odds ratio for the 13 trials was 0.91 (95% confidence interval 0.74 to 1.12). Pooled absolute risk reduction was 1.8% (-2.5% to 5.7%). For the 10 trials that reported death or disability the pooled odds ratio was 0.90 (0.72 to 1.11). For infections of any type the pooled odds ratio was 0.92 (0.69 to 1.23) and for the seven trials reporting gastrointestinal bleeding it was 1.05 (0.44 to 2.52). With only those trials with the best quality of concealment of allocation, the pooled odds ratio estimates for death and death or disability became closer to unity. CONCLUSIONS: This systematic review of randomised controlled trials of corticosteroids in acute traumatic brain injury shows that there remains considerable uncertainty over their effects. Neither moderate benefits nor moderate harmful effects can be excluded. The widely practicable nature of the drugs and the importance of the health problem suggest that large simple trials are feasible and worth while to establish whether there are any benefits from use of corticosteroids in this setting.

Objective Approximately 30 million Americans present to acute care medical settings annually after incurring traumatic injuries. Posttraumatic stress disorder and depressive symptoms are endemic among injury survivors. Our paper is a replication and extension of a previous report documenting a pattern of multiple traumatic life events across patients admitted to Level I trauma centers for an alcohol-related injury. Method This study is a secondary analysis of a nationwide 20-site randomized trial of an alcohol brief intervention with 660 traumatically injured inpatients. Pre-injury trauma history was assessed using the National Comorbidity Survey trauma history screen at the 6 month time point. Results Most common traumatic events experienced by our population of alcohol positive trauma survivors were having had someone close unexpectedly die, followed by having seen someone badly beaten or injured. Of particular note, there is high reported prevalence of rape/sexual assault, and childhood abuse and neglect among physically injured trauma survivors. Additional trauma histories are increasingly common among alcohol-positive patients admitted for a traumatic injury. Conclusions Due to the high rate of experienced multiple traumatic events among acutely injured inpatients, the trauma history screen could be productively integrated into screening and brief intervention procedures developed for acute care settings.

The use of the street drug methylenedioxymethamphetamine (MDMA), commonly referred to as ecstasy, has become increasingly prevalent amongst teenagers and young adults in the United States and many other parts of the world. While most anesthesiologists are facile with the intricacies of managing patients intoxicated by alcohol, cocaine and narcotics the new "club" drugs present a challenge, especially under emergency conditions. MDMA, in particular, is the most commonly abused club drug and potentially one of the most dangerous in the perioperative period. We present a case report of traumatic subarachnoid hemorrhage in a patient with acute MDMA intoxication and a review of the anesthetic implications.

Soft tissue injuries constitute 30-50% of all sports related injuries; however, injury to the latissimus dorsi muscle is quite rare with only a few cases reported in the literature. Herein, we describe an acute traumatic tear of the latissimus dorsi muscle in an elite track athlete, which has not been reported in the track and field sports before. The injury was caused by forceful resisted arm adduction that took place at hurdling and starting from the block. A pseudotumor appearance in the axillary region was misdiagnosed as a mass. The diagnosis was made by ultrasound alone and the patient was managed conservatively. PMID:24765503

Background Neuroimaging studies have implicated limbic, paralimbic, and prefrontal cortex in the pathophysiology of chronic post-traumatic stress disorder (PTSD). However, little is known about the neural substrates of acute PTSD and how they change with symptom improvement. Purpose To examine the neural circuitry underlying acute PTSD and brain function changes during clinical recovery from this disorder. Material and Methods Nineteen acute PTSD patients and nine non-PTSD subjects who all experienced a devastating mining accident underwent clinical assessment as well as functional magnetic resonance imaging (fMRI) scanning while viewing trauma-related and neutral pictures. Two years after the accident, a subgroup of 17 patients completed a second clinical evaluation, of which 13 were given an identical follow-up scan. Results Acute PTSD patients demonstrated greater activation in the vermis and right posterior cingulate, and greater deactivation in the bilateral medial prefrontal cortex and inferior parietal lobules than controls in the traumatic versus neutral condition. At follow-up, PTSD patients showed symptom reduction and decreased activation in the right middle frontal gyrus, bilateral posterior cingulate/precuneus, and cerebellum. Correlation results confirmed these findings and indicated that brain activation in the posterior cingulate/precuneus and vermis was predictive of PTSD symptom improvement. Conclusion The findings support the involvement of the medial prefrontal cortex, inferior parietal lobule, posterior cingulate, and vermis in the pathogenesis of acute PTSD. Brain activation in the vermis and posterior cingulate/precuneus appears to be a biological marker of recovery potential from PTSD. Furthermore, decreased activation of the middle frontal gyrus, posterior cingulate/precuneus, and cerebellum may reflect symptom improvement.

Rupture of the Achilles tendon is a common injury during working years. Aggressive rehabilitation may provide better outcomes, but also a greater chance of re-rupture. To determine if aggressive rehabilitation has better clinical outcomes for Achilles tendon function, Triceps surae function, one-leg heel rise capacity and lower complication rate during twelve weeks after percutaneous Achilles tendon repair compared to conventional rehabilitation. Randomized controlled trial. Thirty-nine patients were prospectively randomized. The aggressive group (n=20, 41.4 ± 8.3 years) received rehabilitation from the first day after surgery. The conventional group (n=19, 41.7 ± 10.7 years) rested for 28 days, before rehabilitation started. The statistical parameters were the Achilles tendon rupture score (ATRS), verbal pain scale, time to return to work, pain medication consumption, Achilles tendon strength, dorsiflexion range of motion (RoM), injured-leg calf circumference, calf circumference difference, one-leg heel rise repetition and difference, re-rupture rate, strength deficit rate, and other complication rates. Mixed-ANOVA and Bonferroni's post hoc test were performed for multiple comparisons. Student's t-test was performed for parameters measured on the 12th week. The aggressive group with respect to the conventional group had a higher ATRS; lower verbal pain score; lower pain medication consumption; early return to work; higher Achilles tendon strength; higher one-leg heel rise repetitions; and lower one-leg heel rise difference. The re-rupture rate was 5% and 5%, the strength deficit rate was 42% and 5%, and other complications rate was 11% and 15% in the conventional and aggressive group, respectively. Patients with Dresden repair and aggressive rehabilitation have better clinical outcomes, Achilles tendon function and one-leg heel rise capacity without increasing the postoperative complications rate after 12 weeks compared to rehabilitation with immobilization and

Objective To evaluate the efficacy and safety of progesterone administrated in patients with acute traumatic brain injury (TBI). Methods PubMed/MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), Clinicaltrials.gov, ISRCTN registry and WHO International Clinical Trials Registry Platform (ICTRP) were searched for randomized controlled trials (RCTs) comparing progesterone and placebo administrated in acute TBI patients. The primary outcome was mortality and the secondary outcomes were unfavorable outcomes and adverse events. A meta-analysis was conducted to evaluate the efficacy and safety of progesterone administrated in patients with acute TBI. Results A total of 6 studies met inclusion criteria, involving 2,476 patients. The risk of bias was considered to be low in 4 studies but high in the other 2 studies. The results of meta-analysis indicated progesterone did not reduce the mortality (RR = 0.83, 95% CI = 0.57–1.20) or unfavorable outcomes (RR = 0.89, 95% CI = 0.78–1.02) of acute TBI patients in comparison with placebo. Sensitivity analysis yielded consistent results. Progesterone was basically safe and well tolerated in TBI patients with the exception of increased risk of phlebitis or thrombophlebitis (RR = 3.03, 95% CI = 1.96–4.66). Conclusions Despite some modest bias, present evidence demonstrated that progesterone was well tolerated but did not reduce the mortality or unfavorable outcomes of adult patients with acute TBI.

Much debate surrounds the mechanisms responsible for the occurrence of blunt traumatic aortic rupture in car accidents, particularly on the role of the inertial body force experienced by the blood due to the abrupt deceleration. The isolated influence of such body forces acting on even simple fluid flows is a fundamental problem in fluid dynamics that has not been thoroughly investigated. This study numerically investigates the fundamental physical problem, where the pulsatile flow in a straight circular pipe is subjected to a transverse body force on a localized volume of fluid. The body force is applied as a brief rectangular impulse in three distinct cases, namely during the accelerating, peak, and decelerating phases of the pulsatile flow. A dimensionless number, termed the degree of influence of the body force (Ψ), is devised to quantify the relative strength of the body force over the flow inertia. The impact induces counter-rotating cross-stream vortices at the boundaries of the forced section accompanied by complex secondary flow structures. This secondary flow is found to develop slowest for an impact occurring during an accelerating flow and fastest during a decelerating flow. The peak skewness of the velocity field, however, occurred at successively later times for the three respective cases. After the impact, these secondary flows act to restore the unforced state and such dominant spatial structures are revealed by proper orthogonal decomposition of the velocity field. This work presents a new class of problems that requires further theoretical and experimental investigation.

There is no consensus regarding the optimal mode of managing the acute traumatic subungual haematoma in the hand. In this context the medical literature was searched systematically and the results analysed. The final dataset consisted of four articles. The complication rates of all forms of treatment were low. The outcome in terms of nail cosmesis was generally good, although the method of outcome measurement was variable in nature. There was no difference in cosmetic outcome when comparing nail bed repair with simple decompression. In conclusion the outcome in terms of nail cosmesis does not appear to be affected by the mode of treatment. The acutely painful subungual haematoma should be decompressed, whether this be done by trephining or nail removal. Future research includes the potential for a randomised controlled trial to compare nail bed repair with trephination.

The psychological characteristics of acute traumatic brain injury (TBI) have received limited research focus, despite empirical evidence of their relevance for subsequent psychological adjustment and early therapeutic intervention. This study addressed a wide range of psychological features in 47 individuals who were hospitalized as a result of acute mild TBI (mTBI). Participants were screened from amongst consecutive TBI admissions for moderate to severe brain injury, and for pre-injury neurological, psychiatric, or substance abuse histories. Clinical and content scale scores on the MMPI-2 were explored in relation to patient gender, age, level of education, and extent of cognitive complaints. The results revealed diverse psychosocial problem areas across the sample, the most common of which were somatic and cognitive complaints, compromised insight, and a naively optimistic self-perception. The mediating roles of injury severity and demographic variables are discussed. Clinical implications and specific recommendations are presented.

Quadriceps tendon rupture is uncommon and often overlooked in emergency. Tearing affects weakening tendon by systemic diseases or some medications. The mechanism is generally indirect. Inability to actively extend the knee associated to a supra-patellar defect evoke easily the diagnosis without other investigations. Surgical repair is realized in emergency to completely restore the extension. We report a case of a patient who has sustained of complete quadriceps tendon tear after a long period of tendon weakening by statin therapy, hypertension and diabetes. The repair has consisted on end-to-end Krackow sutures associated with bone suture to the proximal pole of the patella. Surgeons and emergency physicians must think to this form of extensor apparatus rupture, because early diagnosis leads to early treatment and to best outcomes. PMID:26958106

Objective * These authors contributed equally to this work. To explore tendon-bundle technique for treating Achilles tendon rupture with no defects. Methods Patients with full unilateral Achilles tendon rupture with no defects were included. The Achilles tendon medial edge surgical repair approach was used, revealing horsetail-like rupture bundles. Tendon bundles were anatomically realigned and repaired end-to-end using 5-0 sutures. Patients were followed-up for 1 year, and assessed for differences between the repaired versus healthy limb. Results Out of 24 patients (18 male, 6 female; aged 19-56 years) at 1 year following surgery, mean American Orthopaedic Foot and Ankle Society score was 92.4 ± 5.9; mean differences between the surgically repaired versus contralateral side in dorsiflexion and plantarflexion angle were 3.5 ± 2.3° and 5.6 ± 3.2°, respectively; mean difference in calf circumference between the two sides was 0.9 ± 0.5 cm; and mean increase in Achilles tendon width versus the healthy side was 0.8 ± 0.2 cm. By 1 year post-surgery, there were no significant between-side differences in dorsiflexion and plantarflexion angle, or calf circumference. Conclusions Tendon-bundle surgery resulted in good ankle function restoration and low complication rates. Tendon-bundle surgery may reduce blood supply destruction and maximally preserve Achilles tendon length, and may be effective for treating Achilles tendon rupture with no defects.

Acute traumatic coagulopathy (ATC) is the failure of coagulation homeostasis that can rapidly arise following traumatic injury, hemorrhage, and shock; it is associated with higher injury severity, coagulation abnormalities, and increased blood transfusions. Acute traumatic coagulopathy has historically been defined by a prolonged prothrombin time, although newer, more informative measurements of hemostatic function have been used to improve diagnosis and support clinical decision making. The underlying biochemical mechanisms of and best practice therapeutics for ATC remain under active investigation because of its significant correlation to poor outcomes. The wide range of hypothesized mechanisms for ATC results from the large number of symptoms, phenotypes, and altered states in these patients as observed by multiple research groups. Much like the ancient fable of blind men describing an elephant from their limited perspectives, the limited nature of clinical and laboratory tools used to diagnose coagulopathy or evaluate hemostatic function has made finding causation difficult. The prolonged prothrombin time, degree of fibrinolysis, depletion of coagulation factors and inhibitors, and general failure of the blood have all been identified as being primary indicators for ATC. Therapeutic interventions including recombinant coagulation factors, antifibrinolytics, and blood products have been used with varying degrees of success as they are used to address specific symptoms. To truly understand the causes of ATC, research efforts must recognize the complexity of the hemostatic system and get to the heart of the matter by answering the question: "Is ATC a pathological condition that develops from the observed deficiencies in coagulation, fibrinolysis, and autoregulation, or is ATC an adaptive response generated as the body attempts to restore perfusion and avoid massive organ failure?" Because patient management must proceed without definitive answers regarding the

OBJECTIVE The current gold-standard imaging modality for pediatric traumatic brain injury (TBI) is CT, but it confers risks associated with ionizing radiation. QuickBrain MRI (qbMRI) is a rapid brain MRI protocol that has been studied in the setting of hydrocephalus, but its ability to detect traumatic injuries is unknown. METHODS The authors performed a retrospective cohort study of pediatric patients with TBI who were undergoing evaluation at a single Level I trauma center between February 2010 and December 2013. Patients who underwent CT imaging of the head and qbMRI during their acute hospitalization were included. Images were reviewed independently by 2 neuroradiology fellows blinded to patient identifiers. Image review consisted of identifying traumatic mass lesions and their intracranial compartment and the presence or absence of midline shift. CT imaging was used as the reference against which qbMRI was measured. RESULTS A total of 54 patients met the inclusion criteria; the median patient age was 3.24 years, 65% were male, and 74% were noted to have a Glasgow Coma Scale score of 14 or greater. The sensitivity and specificity of qbMRI to detect any lesion were 85% (95% CI 73%-93%) and 100% (95% CI 61%-100%), respectively; the sensitivity increased to 100% (95% CI 89%-100%) for clinically important TBIs as previously defined. The mean interval between CT and qbMRI was 27.5 hours, and approximately half of the images were obtained within 12 hours. CONCLUSIONS In this retrospective pilot study, qbMRI demonstrated reasonable sensitivity and specificity for detecting a lesion or injury seen with neuroimaging (radiographic TBI) and clinically important acute pediatric TBI.

Traumatic spinal cord injury leads to direct myelin and axonal damage and leads to the recruitment of inflammatory cells to site of injury. Although rodent models have provided the greatest insight into the genesis of traumatic spinal cord injury (TSCI), recent studies have attempted to develop an appropriate non-human primate model. We explored TSCI in a cynomolgus macaque model using a balloon catheter to mimic external trauma to further evaluate the underlying mechanisms of acute TSCI. Following 1hour of spinal cord trauma, there were focal areas of hemorrhage and necrosis at the site of trauma. Additionally, there was a marked increased expression of macrophage-related protein 8, MMP9, IBA-1, and inducible nitric oxide synthase in macrophages and microglia at the site of injury. This data indicate that acute TSCI in the cynomolgus macaque is an appropriate model and that the earliest immunohistochemical changes noted are within macrophage and microglia populations. © 2012 John Wiley & Sons A/S.

The aim of this study was to evaluate, in a meta-analysis, the clinical effectiveness of operative treatment for acute Achilles tendon rupture (AATR) compared with nonoperative treatment. We systematically searched six electronic databases (Medline, Embase, Clinical Ovid, BIOSIS and Cochrane registry of controlled clinical trials) to identify randomised controlled trials (RCTs) in which operative treatment was compared with nonoperative treatment for AATR from 1980 to 2011. Trial quality was assessed using the modified Jadad scale. The data was using fixed-effects and random-effects models with mean differences and risk ratios for continuous and dichotomous variables, respectively. Ten RCTs with a total of 894 patients were screened. The results showed that operative was superior to nonoperative treatment regarding lower risk of re-rupture (P = 0.002) and shorter time for sick leave (P = 0.009) but inferior to nonoperative treatment regarding complication risks (P = 0.004). No significant difference was identified between the two methods regarding the number of patients who successfully returned to pre-injury sports (P = 0.30). Subgroup analyses revealed significant differences in relation to scar adhesion (P < 0.00001), superficial infection (P = 0.05), and sensibility disturbance (P = 0.0003). However, no significant differences were found between the two interventions in relation to deep infection (P = 0.22), deep vein thrombosis (DVT) (P = 0.14), and extreme Achilles tendon lengthening (P = 0.31). Little consensus was obtained in the functional recovery from current trials as a result of an inconsistent assessment system. Compared with conservative treatment, operative treatment can effectively reduce the risk of re-rupture but increase the probability of complications. The increased complication risk may be associated with open repair surgery. However, no sufficient evidence is available from current studies to support the belief that operation may lead to

Quadriceps tendon ruptures are rare and mainly affect patients over 40 years of age who have a systemic disease. The aim of this study was to evaluate the functional and radiological outcomes following surgical repair of acute quadriceps tendon ruptures. This retrospective study included 68 knees in 65 patients (three women, 62 men), having an average age of 55.2 ± 13.9 years. The Lysholm and Tegner scores, patient satisfaction, range of motion and X-rays were evaluated. Fifty knees were evaluated with a mean follow-up of 76±67 months (12-253 months). The average Lysholm score was 93.7±10 (range 56-100, median 99) and 49 of 50 knees (98%) had good or very good subjective results. The average Tegner score was 3.4±1.6 (range 1-9, median 4). At the last follow-up, the average active flexion was 133°±10.8° (range 110°-150°, median 130°). Minor or moderate patellofemoral osteoarthritis was found in 24% of knees, but this was attributed to the surgery or initial injury in only 8% of cases. For 97% of active patients, the surgical repair allowed them to return to work in their pre-injury occupations. Quadriceps tendon ruptures have a good prognosis if they are diagnosed quickly. Treatment consists of surgery and postoperative immobilization for at least 6 weeks. An intensive rehabilitation protocol is also needed to recover good knee function. Level IV. Retrospective study.

Achilles tendon ruptures are becoming more common. Complications after open or minimally invasive surgery are: recurrent rupture (2-8%), wound breakdown, deep infections, granuloma, and fistulas. The authors expose their experience with a personal technique. In 8 patients with acute rupture of Achilles tendon the surgery was performed at least 25 days after trauma. Clinical exam and MR demonstrated in all case a total lesion of tendon. After a posterolateral skin incision the tendon stumps were debrided and suture in end-to-end fashion. A tendon flap was harvested from the proximal part of the tendon, in order to protect and reinforce the suture itself. A plaster cast was applied for 3 weeks and the patients started the rehabilitation protocol. After 4 months all patients returned to pre-injury daily activities. The mean follow up was 13 months (ranged between 6 and 24 months). No major complications occurred. The posterolateral skin incision, not above the tendon, preserves the vascularity of the soft tissues, allows identifying and not accidentally injuring the sural nerve, and prevents the cutaneous scar is overlapped the tendon. In this way is favoured physiological tendon sliding. The preparation of the flap tendon does not weaken the overall strength of the tendon and protects the tendon suture. The tension on sutured stumps is less than being spread over a larger area. In our sample of 8 patients the absence of short-and long-term complications and the rapid functional recovery after surgery suggest that the technique used is safe and effective.

A rare case of acute avulsion of both posterior meniscal roots concomitant with an acute anterior cruciate ligament (ACL) tear in a professional soccer player is described. While avulsion of the lateral meniscal root has been extensively reported in association with ACL injuries, medial root avulsion has never been reported in association with acute ACL. A review of the video documentation of the match accident revealed the exact mechanism of injury was a forceful external rotation of the standing limb.

Conservative "functional" management of acute Achilles tendon ruptures has become increasingly popular. Critical to this is the use of the walking orthosis, which positions the ankle in equinus to allow for early weightbearing. Our aim was to test whether 2 common orthoses achieved a satisfactory equinus position. A total of 11 sequentially treated Achilles tendon ruptures were assigned to either a fixed angle walking boot with wedges (FAWW) or an adjustable external equinus-corrected brace (EEB). The lateral radiographs of the cast immobilized tendons showed a mean tibiotalar angle (TTA) of 56° (range 54° to 57°) and a mean tibio-first metatarsal angle (1MTA) of 74° (range 62° to 85°). The FAWW resulted in a mean TTA of 28° (range 15° to 35°) and 1MTA of 37° (range 30° to 45°). The EEB resulted in a TTA of 48° (range 43° to 45°) and 1MTA of 54° (range 47° to 57°). Ankle equinus was significantly greater with the EEB than with the FAWW (p < .05) and similar to that with an equinus cast. The use of wedges produced an equinus appearance through the midfoot but not at the ankle. We express caution in the use of the FAWW because it is unlikely to achieve sufficient ankle equinus to shorten the Achilles tendon. Copyright © 2017 American College of Foot and Ankle Surgeons.

Meaning is an integral aspect of life that drives behaviours, actions and emotions. Perception of pain is believed to be affected by the meaning of pain. Our primary aim was to investigate and discuss the determinants of meaning in acute pain following a traumatic injury. Using the Interpretive Description approach, a method of qualitative inquiry, 13 adults hospitalised due to their accidental injuries were recruited. Semi-structured interviews that were digitally recorded were used to collect the data. Ethical approval was received by our local Health Research Ethics Board, and all relevant ethical standards were followed as outlined in the approved ethics proposal. The three primary determinants of meaning during an acute pain event, or the experience of acute pain include permanence of injuries, incongruence of care quality, and personal responses to the injury and care received. Although the permanence of an injury is lasting, we did not find any emotional response to this fact while the participants were hospitalised. The emotion characterising the personal response to the perceived poor quality of hospital care received was anxiety. Both the technical and personal components of healthcare quality have the potential to increase the perception of pain. Meanings in an acute pain event are primarily related to the determinants of incongruent care and the personal response to that determinant: anxiety. © 2017 Nordic College of Caring Science.

Traumatic brain injury (TBI) is a significant biomedical problem among military personnel and civilians. There exists an urgent need to develop and refine biological measures of acute brain injury and chronic recovery after brain injury. Such measures "biomarkers" can assist clinicians in helping to define and refine the recovery process and developing treatment paradigms for the acutely injured to reduce secondary injury processes. Recent biomarker studies in the acute phase of TBI have highlighted the importance and feasibilities of identifying clinically useful biomarkers. However, much less is known about the subacute and chronic phases of TBI. We propose here that for a complex biological problem such as TBI, multiple biomarker types might be needed to harness the wide range of pathological and systemic perturbations following injuries, including acute neuronal death, neuroinflammation, neurodegeneration and neuroregeneration to systemic responses. In terms of biomarker types, they range from brain-specific proteins, microRNA, genetic polymorphism, inflammatory cytokines and autoimmune markers and neuro-endocrine hormones. Furthermore, systems biology-driven biomarkers integration can help present a holistic approach to understanding scenarios and complexity pathways involved in brain injury.

Many studies have assessed the predictors of morbidity/mortality of patients with traumatic brain injury (TBI) in acute care. However, with the increasing rate of survival after TBI, more attention has been given to discharge destinations from acute care as an important measure of clinical priorities. This study describes the design of a systematic review compiling and synthesising studies on the prognostic factors of discharge settings from acute care in patients with TBI. This systematic review will be conducted on peer-reviewed studies using seven databases including Medline/Medline in-Process, Embase, Cochrane Database of Systematic Reviews, Cochrane CENTRAL, PsycINFO, CINAHL and Supplemental PubMed. The reference list of selected articles and Google Scholar will also be reviewed to determine other relevant articles. This study will include all English language observational studies that focus on adult patients with TBI in acute care settings. The quality of articles will be assessed by the Quality in Prognostic Studies tool. The results of this review will provide evidence that may guide healthcare providers in making more informed and timely discharge decisions to the next level of care for patient with TBI. Also, this study will provide valuable information to address the gaps in knowledge for future research.

There are few reliable markers for assessing traumatic brain injury (TBI). Elevated levels of oxidative stress have been observed in TBI patients. We hypothesized that oxidation-reduction potential (ORP) could be a potent biomarker in TBI. Two types of ORP were measured in patient plasma samples: the static state of oxidative stress (sORP) and capacity for induced oxidative stress (icORP). Differences in ORP values as a function of time after injury, severity, and hospital discharge were compared using ANOVAs with significance at p ≤ 0.05. Logit regression analyses were used to predict acute outcome comparing ORP, Injury Severity Score (ISS), Abbreviated Injury Scale (AIS), and Glasgow Coma Scale (GCS). Antioxidant capacity (icORP) on day 4 was prognostic for acute outcomes (p < 0.05). An odds ratio of 4.08 was associated with poor acute outcome when icORP > 7.25 μC. IcORP was a better predictor than ISS, AIS, or GCS scores. sORP increased in those with the highest ISS values (p < 0.05). Based on these findings ORP is useful biomarker for severity and acute outcome in TBI patients. Changes in ORP values on day 4 after injury were the most prognostic, suggesting that patients' response to brain injury over time is a factor that determines outcome. PMID:27642494

A content of C-reactive protein (CRP) in the blood serum was determined in 36 patients in acute period of a ruptured intracranial arterial aneurysm (AA). It was significantly more, than in a control group, and have exceeded 10 mg/I in 1 - 4th day of the disease. The level of CRP have had differ, depending on severity of cerebral vasospasm (CVS), determined in accordance to the ultrasound investigation data. In a pronounced CVS in majority of patients the level of CRP in the blood serum have had exceed 10 mg/l, and have secured elevated in a spinal liquor on the 7 - 10th day of the disease, differing from this index in patients with moderately pronounced CVS or without it. In patients with severe invalidization or those, who have died, the level of CRP was trust-worthy higher.

The purpose of this study was to compare the latest patient demographics and rerupture rates of operative versus nonoperative treatment of acute Achilles tendon rupture in the United States. Patients undergoing treatment of an acute Achilles tendon rupture from 2007 to 2011 were identified by cross-referencing ICD-9-CM and CPT codes through the PearlDiver Patient Record Database. In total, 12,570 patients were treated for an acute Achilles tendon rupture. The ratio of operative to nonoperative treatment increased from 1.41 to 1.65. Males were more likely to undergo surgery than females. There were no significant differences in short-term rerupture rate for operative (2.1%) versus nonoperative (2.4%) treatment. The proportion of patients who received operative treatment for an acute Achilles tendon rupture increased slightly during the 5 year period, suggesting that surgeons in the United States have been slower to adopt nonoperative treatment than their European counterparts.

Bloodletting at Jing points has been used to treat coma in traditional Chinese medicine. Mild induced hypothermia has also been shown to have neuroprotective effects. However, the therapeutic effects of bloodletting at Jing points and mild induced hypothermia alone are limited. Therefore, we investigated whether combined treatment might have clinical effectiveness for the treatment of acute severe traumatic brain injury. Using a rat model of traumatic brain injury, combined treatment substantially alleviated cerebral edema and blood-brain barrier dysfunction. Furthermore, neurological function was ameliorated, and cellular necrosis and the inflammatory response were lessened. These findings suggest that the combined effects of bloodletting at Jing points (20 μL, twice a day, for 2 days) and mild induced hypothermia (6 hours) are better than their individual effects alone. Their combined application may have marked neuroprotective effects in the clinical treatment of acute severe traumatic brain injury. PMID:27482221

The acute rupture of the Achilles tendon is a protracted injury. Surgery is only the beginning of a long rehabilitation period. Therefore, the rehabilitation protocol is an integral aspect to restore the pre-injury activity level. Despite several trials available comparing different treatment regimes, there is still no consensus regarding the optimal protocol. Consequently, the aim of our study was to systematically search the evidence available and define a precise rehabilitation programme after operative repair of acute Achilles tendon rupture based on the trials with the highest level of evidence. We performed a systematic literature search in Medline, Embase and Cochrane library. We identified twelve randomized controlled trials comparing different treatment regimes after operative repair of the Achilles tendon. Five trials compared full to non weight bearing, all applying immobilization in equinus. Immediate full weight bearing led to significant higher patient satisfaction, earlier ambulation and return to pre-injury activity. Four trials compared early ankle mobilization to immobilization. All trials found mobilization to be superior as it shortens time to return to work and sports significantly. Three trials compared the combination of full weight bearing and early ankle mobilization to immobilization. This combination was most beneficial. Patients showed significantly higher satisfaction, less use of rehabilitation resources, earlier return to pre-injury activities and further demonstrated significantly increased calf muscle strength, reduced atrophy and tendon elongation. No study found an increased rerupture rate for the more progressive treatment. In conclusion, the rehabilitation protocol after Achilles tendon repair should allow immediate full weight bearing. After the second postoperative week controlled ankle mobilization by free plantar flexion and limited dorsiflexion at 0° should be applied. Copyright © 2014 Elsevier Ltd. All rights reserved.

The purpose of this study was to present the functional outcomes of percutaneous tenorrhaphy of the Achilles tendon with a minimum follow-up of 10 years. The medical records of patients who underwent percutaneous surgery for acute unilateral Achilles tendon rupture between 2000 and 2004 were retrospectively reviewed. A total of 11 male patients met the inclusion criteria and were followed for a mean of 12.6 years (range: 10-13 years). The average age at the time of surgery was 39.3 years (range: 29-53 years). Patients returned to work at an average of 2.7 months (range: 1-4 months) after surgery and to normal daily activities (NDA) at an average of 4.1 months (range: 3-6 months) postoperatively. The mean strength ratio between the injured and normal sides was 90%. Compared with the contralateral normal side, the thickness of the operated tendon increased by a mean of 0.7 cm, while the circumference of the affected calf diminished by a mean of 1.1 cm. No difference in active and passive range of motion (ROM) was recorded between the affected and the contralateral normal ankle joints. Isometric plantar flexion was 87% of normal. Sensory impairment in the territory of the sural nerve was identified in 1 patient immediately after surgery. The sensory defect had completely resolved by 6 months postoperatively. Long-term outcomes of our series support the effectiveness of percutaneous tenorrhaphy in Achilles function rehabilitation of patients with acute ruptures.

We retrospectively compared the outcomes of early functional weight-bearing after use of 2 different approaches (minimally invasive, standard) for surgical repair of the Achilles tendon. We reviewed the cases of 63 consecutive patients who underwent repair of an acute closed Achilles tendon rupture and had follow-up of at least 6 months. Of these 63 patients, 33 were treated with a minimally invasive posterolateral approach (minimal group), and 30 were treated with a standard posteromedial approach (standard group). Two weeks after surgery, each patient was allowed to weight-bear as tolerated in a controlled ankle movement boot with a 20° heel wedge. At 6 weeks, the patient was placed in a regular shoe with a heel lift. We examined range of motion and incidence of reruptures, sural nerve injuries, and wound complications at 6 weeks and 3 months and calf strength at 6 months. Neither group had any reruptures. Mean incision length was 2.5 cm (minimal group) and 7.2 cm (standard group). One patient (3.2%) in the minimal group and 6 patients (20%) in the standard group developed a superficial wound infection. Four (12.9%) of 31 minimal patients and no standard patients developed a sural nerve deficit. There were statistically significant differences between the groups' wound complication rates (P=.04) and nerve injury rates (P=.043). At final follow-up, the groups did not differ in their functional outcomes (ability to perform a single heel raise, American Orthopaedic Foot and Ankle Society scores). Used after a minimally invasive posterolateral or standard posteromedial approach, early functional weightbearing is an effective and safe method for treating acute ruptures of the Achilles tendon, and it has a lower rate of soft-tissue complications. A standard posteromedial approach has a higher rate of wound complications, and a minimally invasive posterolateral approach has a higher rate of sural nerve injury.

Monochorionic (MC) twin pregnancies are at increased risk of several complications including acute or chronic twin-twin transfusion syndrome (TTTS) and twin anemia-polycythemia sequence (TAPS). Both TTTS and TAPS result from inter-twin fetofetal transfusion through the placental vascular anastomoses. In addition, MC twin pregnancies are at increased risk of having a velamentous cord insertion, which has been linked with poor perinatal outcome due to risk of rupture of the velamentous vessels. In sporadic cases, these vascular connections may have a positive effect instead of a deleterious effect. We present a case of acute fetal distress in a MC twin pregnancy caused by acute hemorrhage following rupture of velamentous vessels. An emergency cesarean section delivery was performed at 29+2 weeks' gestation. One infant was severely anemic at birth and required immediate treatment with volume expansion and blood transfusion. Acute fetal blood loss through the ruptured vessels led to an acute fetofetal transfusion from the co-twin through the placental vascular anastomoses. Delayed intervention could have resulted in severe hypovolemic shock and acute anemia in both fetuses. Instead, in the current case, placental vascular anastomoses had a transient protective role and allowed transfusion of blood from one co-twin into the circulation of the anemic twin.

We describe the first report of haemorrhaged schwannoma presenting with acute high radial nerve palsy after traumatic injury of the upper arm. Anticoagulant therapy may induce intratumoural haemorrhage, resulting in symptomatic increases in size within the limited space of the upper arm. The radiological, surgical and pathological findings are discussed.

A 27-year-old patient presented with severe headache and seizures about a month after the initial head trauma. Computed tomography (CT) brain scan revealed acute subdural bleed continuous into the interhemispheric region, with no subarachnoid haemorrhage. This was due to rupture of a traumatic pericallosal artery aneurysm. This represents a rare case of traumatic pericallosal artery aneurysm presenting with subdural haematoma without subarachnoid haemorrhage.

To determine acceptability and preliminary effectiveness of Emergency Department (ED) Social Work Intervention for Mild Traumatic Brain Injury (SWIFT-Acute) on alcohol use, community functioning, depression, anxiety, post-concussive symptoms, post-traumatic stress disorder and service use. This study enrolled 64 patients who received head CT after mild traumatic brain injury (mTBI) and were discharged <24 hours from a Level 1 trauma centre ED. The cohort study compared outcomes for SWIFT-Acute (n = 32) and Usual Care (n = 32) 3 months post-injury. SWIFT-Acute includes education about symptoms and decreasing alcohol use, coping strategies, reassurance and education about recovery process and follow-up guidelines and resources. Alcohol Use Disorders Identification Test (AUDIT), Community Integration Questionnaire (CIQ), Patient Health Questionnaire-4, Rivermead Post-concussion Symptoms Questionnaire, PTSD Checklist-Civilian, acceptability and service use surveys. Paired t-test revealed SWIFT-Acute group maintained pre-injury community functioning; Usual Care significantly declined in functioning on the CIQ. Both groups reported 'hazardous' pre-injury drinking on AUDIT. Wilcoxon Signed Rank test showed the SWIFT-Acute group significantly reduced alcohol use; the Usual Care group did not. Both groups significantly increased medical service use. No statistically significant differences were found on other measures. Acceptability ratings were extremely high. SWIFT-Acute was acceptable to patients. There is preliminary evidence of effectiveness for reducing alcohol use and preventing functional decline. Future randomized studies are needed.

Atraumatic splenic rupture is a rare complication of a pancreatic pseudocyst (PP), described in the setting of chronic pancreatitis. There is common understanding, within the literature, that an inflammatory process at the tail of the pancreas may disrupt the spleen and result in such splenic complications. The authors present a case report of a 29-year-old male with a PP, associated with chronic pancreatitis. The patient had a history of excessive alcohol intake and presented to the emergency department with a short history of abdominal pain and vomiting. He denied any significant history of trauma and serum amylase levels were normal. An admission computed tomography (CT) scan of the abdomen confirmed the presence of a PP in direct contact with the spleen. The CT also demonstrated a heterogenous hypodense area of the splenic hilum, along with perisplenic fluid. The patient was admitted for observation. His abdominal pain progressed, and he became haemodynamically unstable. An emergency ultrasound scan (USS) at this time revealed intra-abdominal haemorrhage. A subsequent CT confirmed splenic rupture, which was managed surgically with a full recovery. Few such cases are documented within the literature and more understanding of preempting such events is needed. PMID:27843669

To determine the success of distal biceps repair in a high-demand military population and to comparatively evaluate the perioperative risk profile, functional results, and adverse patient outcomes of a single- versus 2-incision technique within this high-risk group. Between 2007-2013, all military service members undergoing primary surgical repair for distal biceps rupture through the Military Health System were isolated. Patients with allograft tendon reconstruction, revision procedures, nonmilitary status, and/or follow-up of less than 24 month were excluded. Demographic data (age, limb dominance) and surgical variables (time to surgery, surgical technique) were extracted, and rates of perioperative complications, rerupture, reoperation, revision, and inability to return to preinjury function were recorded. Logistic regression analysis was performed to evaluate for prognostic risk factors, whereas the Fisher exact test was used for comparative analysis. A total of 290 patients met the inclusion criteria, including 44 (15.2%) with a delayed presentation; all patients were men, with an average age of 38.9 years (range, 20-61 years). A single-incision technique was performed in 75.4% (n = 214) versus a 2-incision technique in 24.6% (n = 70), and a cortical button was the predominant fixation construct (73.4%). Reruptures occurred in 7 patients (2.4%), and 3 individuals (1.0%) had significant elbow dysfunction postoperatively. When we compared the overall complication rates, the 2-incision technique (7.1%, n = 5) was not significantly different from the single-incision repair (16.4%, n = 35; P = .0732). Tobacco use was significantly associated with risk of rerupture (odds ratio, 4.86; P = .0423) or combined surgical and clinical failures (odds ratio, 5.64; P = .0091), whereas age, limb dominance, time to surgery, fixation construct, and surgical technique were not statistically significant (P > .05). Among active patients, a single-volar incision technique

Acute seizures frequently occur following severe traumatic brain injury (TBI) and have been associated with poor patient prognosis. Silent or nonconvulsive seizures (NCS) manifest in the absence of motor convulsion, can only be detected via continuous electroencephalographic (EEG) recordings, and are often unidentified and untreated. Identification of effective anti-epileptic drugs (AED) against post-traumatic NCS remains crucial to improve neurological outcome. Here, we assessed the anti-seizure profile of ethosuximide (ETX, 12.5-187.5 mg/kg) and phenytoin (PHT, 5-30 mg/kg) in a spontaneously occurring NCS model associated with penetrating ballistic-like brain injury (PBBI). Rats were divided between two drug cohorts, PHT or ETX, and randomly assigned to one of four doses or vehicle within each cohort. Following PBBI, NCS were detected by continuous EEG monitoring for 72 h post-injury. Drug efficacy was evaluated on NCS parameters of incidence, frequency, episode duration, total duration, and onset latency. Both PHT and ETX attenuated NCS in a dose-dependent manner. In vehicle-treated animals, 69-73% experienced NCS (averaging 9-10 episodes/rat) with average onset of NCS occurring at 30 h post-injury. Compared with control treatment, the two highest PHT and ETX doses significantly reduced NCS incidence to 13-40%, reduced NCS frequency (1.8-6.2 episodes/rat), and delayed seizure onset: <20% of treated animals exhibited NCS within the first 48 h. NCS durations were also dose-dependently mitigated. For the first time, we demonstrate that ETX and PHT are effective against spontaneously occurring NCS following PBBI, and suggest that these AEDs may be effective at treating post-traumatic NCS.

Plaque rupture and erosion are the 2 most common mechanisms for acute coronary syndromes. However, the outcome of these 2 distinct pathologies in patients with acute coronary syndromes has never been studied. We retrospectively studied 141 patients with acute coronary syndromes who underwent optical coherence tomography (OCT) imaging of the culprit lesion prior to stenting from the Massachusetts General Hospital OCT Registry. Management (stent versus no stent), poststent OCT findings, and outcomes were compared. Among the 141 culprit lesions, rupture was found in 79 (56%) patients and erosion in 62 (44%). Stent implantation was performed in 77 (97.5%) patients with rupture versus 49 (79.0%) in those with erosion (P<0.001). Immediately after percutaneous coronary intervention, OCT showed a higher incidence of malapposition (37.5% versus 7.3%, P<0.001), thrombus (59.4% versus 14.6%, P<0.001), and protrusion (93.8% versus 73.2%, P=0.008) in the rupture group compared with the erosion group. Plaque rupture was associated with a higher incidence of no reflow or slow flow and distal embolization. Although cardiac event rates were comparable between the two groups at the 1-year follow-up, none of the erosion patients who were treated conservatively without stenting had adverse cardiac events. Unfavorable poststent OCT findings were more frequent in rupture patients compared with erosion patients. A subset of erosion patients who were treated conservatively without stenting remained free of adverse cardiac events for up to 1 year. © 2017 The Authors.

Background: Obesity and its consequences affect patients with spinal cord injury (SCI). There is a paucity of data with regard to the dietary intake patterns of patients with SCI in the acute inpatient rehabilitation setting. Our hypothesis is that acute rehabilitation inpatients with SCI consume significantly more calories and protein than other inpatient rehabilitation diagnoses. Objective: To compare calorie and protein intake in patients with new SCI versus other diagnoses (new traumatic brain injury [TBI], new stroke, and Parkinson’s disease [PD]) in the acute inpatient rehabilitation setting. Methods: The intake of 78 acute rehabilitation inpatients was recorded by registered dieticians utilizing once-weekly calorie and protein intake calculations. Results: Mean ± SD calorie intake (kcal) for the SCI, TBI, stroke, and PD groups was 1,967.9 ± 611.6, 1,546.8 ± 352.3, 1,459.7 ± 443.2, and 1,459.4 ± 434.6, respectively. ANOVA revealed a significant overall group difference, F(3, 74) = 4.74, P = .004. Mean ± SD protein intake (g) for the SCI, TBI, stroke, and PD groups was 71.5 ± 25.0, 61.1 ± 12.8, 57.6 ± 16.6, and 55.1 ± 19.1, respectively. ANOVA did not reveal an overall group difference, F(3, 74) = 2.50, P = .066. Conclusions: Given the diet-related comorbidities and energy balance abnormalities associated with SCI, combined with the intake levels demonstrated in this study, education with regard to appropriate calorie intake in patients with SCI should be given in the acute inpatient rehabilitation setting.

Traumatic acute subdural hematoma (ASDH) is a major clinical entity in traumatic brain injury (TBI). It acts as a space occupying lesion to increase intracranial pressure, and is often complicated by co-existing lesions, and is modified by cerebral blood flow (CBF) changes, coagulopathy, and delayed hematomas. Because of its complicated pathophysiology, the mortality of ASDH is still remaining high. In this review article, its epidemiology, pathophyiology, surgical treatment, and salvage ability are described. With regard to epidemiology, as the population ages, growing number of elderly patients with ASDH, especially patients with prehospital anticoagulant and antiplatelets, increase. Concerning pathophysiology, in addition to well-known initial intracranial hypertension and subsequent ischemia, delayed hyperemia/hyperperfusion, or delayed hematoma is being recognized frequently in recent years. However, optimal treatments for these delayed phenomenons have not been established yet. With regard to surgical procedures, all of craniotomy, decompressive craniectomy, and initial trephination strategies seem to be effective, but superiority of each procedure have not been established yet. Since Glasgow Coma Scale (GCS) scores, age, papillary reaction, and computed tomographic findings are strongly correlated to outcome, each factor has been investigated as an indicator of salvage ability. None of them, however, has been defined as such one. In future studies, epidemiological changes as population ages, management of delayed pathophysiology, superiority of each surgical procedures, and salvage ability should be addressed. PMID:25367584

The study explored whether premorbid substance use disorder (SUD) predicts acute traumatic brain injury (TBI) outcomes. 143 participants with moderate (34.2%) and severe (65.8%) TBI were enrolled at two Level 1 trauma center inpatient brain injury rehabilitation units. Acute outcomes were measured with the Disability Rating Scale (DRS), the FIMTM; self and informant ratings of the Patient Competency Rating Scale (PCRS); self and family rating of the Frontal Systems Behavioral Scale (FrSBe), and the Neurobehavioral Rating Scale-Revised (NRS-R). Hierarchical linear modeling revealed that SUD history significantly predicted trajectories of PCRS clinician ratings, PCRS self-family and PCRS self-clinician discrepancy scores, and more negative FrSBE family ratings. These findings indicate comparatively greater post-injury executive functions (EF) impairments, particularly self-awareness (SA) of injury-related deficits, for those with SUD history. No significant SUD*time interaction effect was found for FIM or NRS-R scores. SUD history and TBI are associated with impaired SA and EF but their co-occurrence is not a consistent predictor of acute post-injury functional outcomes. Pre-morbid patient characteristics and rater expectations and biases may moderate associations between SA and recovery after TBI.

Executive dysfunction in college students who have had an acute traumatic brain injury (TBI) was investigated. The cognitive, behavioral, and metacognitive effects on college students who endorsed experiencing a brain injury were specifically explored. Participants were 121 college students who endorsed a mild TBI, and 121 college students with no history of a TBI were matched on sex and ethnicity to examine potential differences between groups. Participants completed the Dysexecutive Questionnaire (DEX). A Rasch analysis indicated that the TBI group had significantly higher total scores on the DEX than the control group. Moreover, when compared with the control group, the students with a TBI had higher scores on all 3 subcomponents of the DEX. These findings suggest that students who endorse brain injuries may experience more difficulty with specific facets of college. Thus, the importance of academic and personal resources available for students with a TBI is discussed.

In acute traumatic cervical spinal cord injury (SCI) patients, we sought to characterize how objective MRI measures of injury change during the first 3 week post-injury. Six MRI scans each were planned in 19 cervical SCI patients within the first 3 week post-injury. Length of cord edema, maximum spinal cord compression, maximum canal compromise, and presence and length of hematoma were measured. Length of spinal cord edema increased in the first 48 h after SCI, followed by a gradual decrease in the 3 weeks after injury. This was predominantly seen in the more severe grades of SCI. Hematoma in the spinal cord was seen in all AIS-A and B patients. This study demonstrates the dynamic nature of imaging changes on MRI in the first weeks after injury and highlights the importance of taking into account the timing of imaging when interpreting objective measures of damage.

Open repair of Achilles tendon rupture has been associated with higher levels of wound complications than those associated with percutaneous repair. However, some studies suggest there are higher rerupture rates and sural nerve injuries with percutaneous repair. We compared the two types of repairs in terms of (1) function (muscle strength, ankle ROM, calf and ankle perimeter, single heel rise tests, and work return), (2) cosmesis (length scar, cosmetic appearance), and (3) complications. We retrospectively reviewed 32 surgically treated patients with Achilles rupture: 17 with percutaneous repair and 15 with open repair. All patients followed a standardized rehabilitation protocol. The minimum followup was 6 months (mean, 18 months; range, 6-48 months). We observed similar values of plantar flexor strength, ROM, calf and ankle perimeter, and single heel raising test between the groups. Mean time to return to work was longer for patients who had open versus percutaneous repair (5.6 months versus 2.8 months). Mean scar length was greater in the open repair group (9.5 cm versus 2.9 cm). Cosmetic appearance was better in the percutaneous group. Two wound complications and one rerupture were found in the open repair group. One case of deep venous thrombosis occurred in the percutaneous repair group. All complications occurred before 6 months after surgery. We identified no patients with nerve injury. Percutaneous repair provides function similar to that achieved with open repair, with a better cosmetic appearance, a lower rate of wound complications, and no apparent increase in the risk of rerupture. Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Well-documented potential cardiovascular complications associated with the use of contrast media include bradycardia, hypotension, arrhythmia, and conduction disturbances. Rupture of the myocardium after acute myocardial infarction is a known cause of death, but has yet to be recognised as a potential complication of the use of a bolus injection of contrast medium. On the contrary, contrast-enhanced computed tomographic studies have been performed widely for the diagnosis and evaluation of myocardial infarction. We report a case of complicated myocardial rupture after a single bolus injection of contrast medium during a computed tomographic study in an elderly woman with acute myocardial infarction, which led to cardiac tamponade and rapid death. Although rare, this should alert us to the need for cautious use of contrast medium in patients with acute myocardial infarction.

The purpose of this systematic review was to evaluate and meta-analyse the current evidence for the use of calcium channel blockers (CCBs) in the treatment of acute traumatic brain injury (TBI) and traumatic subarachnoid haemorrhage (tSAH). A systematic search of clinical trials.gov, Cochrane library databases, EMBASE, MEDLINE, Web of science search and WHO trial registry, plus hand-searching of grey literature, was undertaken in March 2013. Two reviewers independently extracted the data using a pre-defined data extraction form. RevMan 5 software was used to synthesise data and calculate the risk ratio (RR) based on event rates as well as the 95% confidence interval (CI). Finally, nine RCTs with a total of 2182 patients were included. Meta-analysis showed that there was no difference between CCBs and control groups for rates of mortality (n=1337, 5 RCTs, RR 0.93 CI 0.77-1.12). In a subgroup tSAH analysis, the difference was not significant (n=389, 2 RCTs, RR 0.73 CI 0.53-1.02). There were slightly fewer unfavourable outcomes in the treatment group, but the difference was not statistically significant (n=2101, 8 RCTs, RR 0.90 CI 0.76-1.08). In the subgroup tSAH analysis, again, the difference did not reach statistical significance (n=1074, 5 RCTs, RR 0.95 CI 0.73-1.24). It seems that larger, well-designed RCTs are necessary in order to ascertain any clinical benefit CCBs may or may not have for the treatment of acute TBI. Crown Copyright © 2013.

Thrombelastography (TEG) is suggested as an optimal instrument for the identification of acute traumatic coagulopathy-induced alterations in coagulation status. Patient whole blood (WB) used in TEG analysis is generally collected from a large blood vessel containing representative systemic blood, often close to 40% hematocrit (Hct). Trauma patients often exhibit bleeding from the microvasculature. This study examines early coagulation function changes at the simulated microvascular level based on altered Hct and pH in vitro through TEG analyses of normal donor blood. Anticoagulated normophysiologic fresh human blood was centrifuged. Individual component effects on coagulation were investigated through variable recombination groups: platelet-rich plasma (PRP), platelet-poor plasma (PPP), and red blood cells (RBCs), which were compared with WB. Acute traumatic coagulopathy-induced acidic microvascular environment was simulated and investigated using tissue factor-activated TEG analysis of variable Hct (40%, 30%, 20%, and 0%) samples and variable [H]. Incremental replacement of RBC with either PPP or normal saline (NS) simulated resuscitation in vitro was also conducted under similar conditions. Only acidified PRP reflected loss of clot strength. Acidified PRP and PPP were delayed equally in clot time. In all groups, inclusion of RBCs normalized clot time. RBC replacement with PPP significantly delayed clot time when samples were acid-challenged, signifying greater acid effect in low Hct microvascular beds. NS simulated resuscitation incurred even greater clotting delays. Acidemia-induced coagulopathy at the level of the capillary Hct (1) is more severe than at higher Hct levels (larger blood vessels), (2) shows that simulated resuscitation with NS causes greater increases in clot time and decreases in clot strength beyond that which occurs with plasma replacement, and (3) may not accurately be portrayed through common TEG practice of testing systemic WB of greater

The purpose of this work was to investigate the effect of early and long-term low-level laser therapy (LLLT) on oxidative stress and inflammatory biomarkers after acute-traumatic muscle injury in Wistar rats. Animals were randomly divided into the following four groups: control group (CG), muscle injury group (IG), CG + LLLT, and IG + LLLT: laser treatment with doses of 3 and 5 J/cm(2). Muscle traumatic injury was induced by a single-impact blunt trauma in the rat gastrocnemius. Irradiation for 3 or 5 J/cm(2) was initiated 2, 12, and 24 h after muscle trauma induction, and the treatment was continued for five consecutive days. All the oxidant markers investigated. namely thiobarbituric acid-reactive substance, carbonyl, superoxide dismutase, glutathione peroxidase, and catalase, were increased as soon as 2 h after muscle injury and remained increased up to 24 h. These alterations were prevented by LLLT at a 3 J/cm(2) dose given 2 h after the trauma. Similarly, LLLT prevented the trauma-induced proinflammatory state characterized by IL-6 and IL-10. In parallel, trauma-induced reduction in BDNF and VEGF, vascular remodeling and fiber-proliferating markers, was prevented by laser irradiation. In order to test whether the preventive effect of LLLT was also reflected in muscle functionality, we tested the locomotor activity, by measuring distance traveled and the number of rearings in the open field test. LLLT was effective in recovering the normal locomotion, indicating that the irradiation induced biostimulatory effects that accelerated or resolved the acute inflammatory response as well as the oxidant state elicited by the muscle trauma.

The causes of post-traumatic acute kidney injury (AKI) are multifactorial, and shock associated with major trauma has been proposed to result in inadequate renal perfusion and subsequent AKI in trauma patients. This study aimed to investigate the true incidence and clinical presentation of post-traumatic AKI in hospitalized adult patients and its association with shock at a Level I trauma center. Detailed data of 78 trauma patients with AKI and 14,504 patients without AKI between January 1, 2009 and December 31, 2014 were retrieved from the Trauma Registry System. Patients with direct renal trauma were excluded from this study. Two-sided Fisher's exact or Pearson's chi-square tests were used to compare categorical data, unpaired Student's t-test was used to analyze normally distributed continuous data, and Mann-Whitney's U test was used to compare non-normally distributed data. Propensity score matching with a 1:1 ratio with logistic regression was used to evaluate the effect of shock on AKI. Patients with AKI presented with significantly older age, higher incidence rates of pre-existing comorbidities, higher odds of associated injures (subdural hematoma, intracerebral hematoma, intra-abdominal injury, and hepatic injury), and higher injury severity than patients without AKI. In addition, patients with AKI had a longer hospital stay (18.3 days vs. 9.8 days, respectively; P < 0.001) and intensive care unit (ICU) stay (18.8 days vs. 8.6 days, respectively; P < 0. 001), higher proportion of admission into the ICU (57.7% vs. 19.0%, respectively; P < 0.001), and a higher odds ratio (OR) of short-term mortality (OR 39.0; 95% confidence interval, 24.59-61.82; P < 0.001). However, logistic regression analysis of well-matched pairs after propensity score matching did not show a significant influence of shock on the occurrence of AKI. We believe that early and aggressive resuscitation, to avoid prolonged untreated shock, may help to prevent the occurrence

Functional neuroimaging studies in mild traumatic brain injury (mTBI) have been largely limited to patients with persistent post-concussive symptoms, utilizing images obtained months to years after the actual head trauma. We sought to distinguish acute and delayed effects of mild traumatic brain injury on working memory functional brain activation patterns < 72 hours after mild traumatic brain injury (mTBI) and again one-week later. We hypothesized that clinical and fMRI measures of working memory would be abnormal in symptomatic mTBI patients assessed < 72 hours after injury, with most patients showing clinical recovery (i.e., improvement in these measures) within 1 week after the initial assessment. We also hypothesized that increased memory workload at 1 week following injury would expose different cortical activation patterns in mTBI patients with persistent post-concussive symptoms, compared to those with full clinical recovery. We performed a prospective, cohort study of working memory in emergency department patients with isolated head injury and clinical diagnosis of concussion, compared to control subjects (both uninjured volunteers and emergency department patients with extremity injuries and no head trauma). The primary outcome of cognitive recovery was defined as resolution of reported cognitive impairment and quantified by scoring the subject's reported cognitive post-concussive symptoms at 1 week. Secondary outcomes included additional post-concussive symptoms and neurocognitive testing results. We enrolled 46 subjects: 27 with mild TBI and 19 controls. The time of initial neuroimaging was 48 (+22 S.D.) hours after injury (time 1). At follow up (8.7, + 1.2 S.D., days after injury, time 2), 18 of mTBI subjects (64%) reported moderate to complete cognitive recovery, 8 of whom fully recovered between initial and follow-up imaging. fMRI changes from time 1 to time 2 showed an increase in posterior cingulate activation in the mTBI subjects compared to

To examine whether traumatic subarachnoid hemorrhage (TSAH) caused by severe diffuse brain injury leads to delayed ischemic brain damage and secondary deterioration of outcome, as does aneurysmal subarachnoid hemorrhage (ASAH). We examined 99 patients with diffuse brain injury with TSAH and 114 patients with ASAH. Computed tomographic (CT) findings, cerebral blood flow, and neurological outcomes were assessed during the acute and subacute phases and were compared between the two groups. The distribution of subarachnoid hemorrhage on the CT scans differed between the two groups. Unlike ASAH, TSAH was not limited to cisterns surrounding the circle of Willis but extended to supratentorial regions and interhemispheric fissures. Computed tomography-detected subarachnoid hemorrhage disappeared very early with TSAH and gradually with ASAH. In the ASAH group, mean cerebral blood flow decreased to 75% of normal during the acute phase and decreased a further 10% during the subacute phase. In the TSAH group, mean cerebral blood flow decreased to 85% of normal during the acute phase and increased slightly during the subacute phase. Neurological deterioration and in-hospital death peaked on Day 0 in association with TSAH and showed twin peaks in association with ASAH. The incidence of low-density areas on the CT scans was significantly higher with ASAH than with TSAH. All low-density areas on the CT scans of patients with ASAH corresponded to vascular territories, but low-density areas on the CT scans of patients with TSAH were rarely associated with vascular territories and contained deep-seated or gliding contusion types. The findings suggest that the incidence of vasospasm is low in association with TSAH and that the cause is different compared with ASAH. There is no evidence that the presence of TSAH in cases of diffuse brain injury leads to delayed ischemic brain damage and secondary deterioration of outcome.

The purpose of this study is to investigate the incidence of acute Achilles tendon rupture in Denmark from 1994 to 2013 with focus on sex, age, geographical areas, seasonal variation and choice of treatment. The National Patient Registry was retrospectively searched to find the number of acute Achilles tendon rupture in Denmark during the time period of 1994-2013. Regional population data were retrieved from the services of Statistics Denmark. During the 20-year period, 33,160 ruptures occurred revealing a statistically significant increase in the incidence (p < 0.001, range = 26.95-31.17/100,000/year). Male-to-female ratio was 3:1 and average age 45 years for men and 44 years for women. There was a statistically significant increasing incidence for people over 50 years. A higher incidence in rural compared with urban geographical areas was found, but this was not statistically significant. There was a statistically significant decreasing incidence of patients treated with surgery from 16.9/10(5) in 1994 to 6.3/10(5) in 2013. The incidence of acute Achilles tendon rupture increased from 1994 to 2013 based on increasing incidence in the older population. There was no difference in incidence of acute Achilles tendon rupture in the rural compared with urban geographical areas. A steady decline in surgical treatment was found over the whole period, with a noticeable decline from 2009 to 2013, possibly reflecting a rapid change in clinical practice following a range of high-quality randomized clinical trials (RCT).

Abstract Reliable diagnosis of traumatic brain injury (TBI) is a major public health need. Glial fibrillary acidic protein (GFAP) is expressed in the central nervous system, and breakdown products (GFAP-BDP) are released following parenchymal brain injury. Here, we evaluate the diagnostic accuracy of elevated levels of plasma GFAP-BDP in TBI. Participants were identified as part of the prospective Transforming Research And Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) Study. Acute plasma samples (<24 h post-injury) were collected from patients presenting with brain injury who had CT imaging. The ability of GFAP-BDP level to discriminate patients with demonstrable traumatic lesions on CT, and with failure to return to pre-injury baseline at 6 months, was evaluated by the area under the receiver operating characteristic curve (AUC). Of the 215 patients included for analysis, 83% had mild, 4% had moderate, and 13% had severe TBI; 54% had acute traumatic lesions on CT. The ability of GFAP-BDP level to discriminate patients with traumatic lesions on CT as evaluated by AUC was 0.88 (95% confidence interval [CI], 0.84–0.93). The optimal cutoff of 0.68 ng/mL for plasma GFAP-BDP level was associated with a 21.61 odds ratio for traumatic findings on head CT. Discriminatory ability of unfavorable 6 month outcome was lower, AUC 0.65 (95% CI, 0.55–0.74), with a 2.07 odds ratio. GFAP-BDP levels reliably distinguish the presence and severity of CT scan findings in TBI patients. Although these findings confirm and extend prior studies, a larger prospective trial is still needed to validate the use of GFAP-BDP as a routine diagnostic biomarker for patient care and clinical research. The term “mild” continues to be a misnomer for this patient population, and underscores the need for evolving classification strategies for TBI targeted therapy.

Acute traumatic coagulopathy has been associated with shock and tissue injury, and may be mediated via activation of the protein C pathway. Patients with acute traumatic coagulopathy have prolonged PT and PTT, and decreased activity of factors V and VIII; they are also hypocoagulable by thromboelastometry (ROTEM) and other viscoelastic assays. To test the etiology of this phenomenon, we hypothesized that such coagulopathy could be induced in vitro in healthy human blood with the addition of activated protein C (aPC). Whole blood was collected from 20 healthy human subjects, and was "spiked" with increasing concentrations of purified human aPC (control, 75, 300, 2000 ng/mL). PT/PTT, factor activity assays, and ROTEM were performed on each sample. Mixed effect regression modeling was performed to assess the association of aPC concentration with PT/PTT, factor activity, and ROTEM parameters. In all subjects, increasing concentrations of aPC produced ROTEM tracings consistent with traumatic coagulopathy. ROTEM EXTEM parameters differed significantly by aPC concentration, with stepwise prolongation of clotting time (CT) and clot formation time (CFT), decreased alpha angle (α), impaired early clot formation (a10 and a20), and reduced maximum clot firmness (MCF). PT and PTT were significantly prolonged at higher aPC concentrations, with corresponding significant decreases in factor V and VIII activity. A phenotype of acute traumatic coagulopathy can be induced in healthy blood by the in vitro addition of aPC alone, as evidenced by viscoelastic measures and confirmed by conventional coagulation assays and factor activity. This may lend further mechanistic insight to the etiology of coagulation abnormalities in trauma, supporting the central role of the protein C pathway. Our findings also represent a model for future investigations in the diagnosis and treatment of acute traumatic coagulopathy.

The choice of rehabilitation management after the surgical repair of acute Achilles tendon (AT) ruptures remains controversial because of insufficient clinical evidence. The current study analyzes the postoperative rehabilitation of AT ruptures based on the current clinical evidence. To identify and analyze the high-level clinical evidence regarding postoperative rehabilitation after the surgical repair of AT ruptures. Subgroup analyses were also performed to obtain more reliable and specific results. Meta-analysis. The studies were retrieved by searching the Medline, Embase, and Cochrane databases through the OVID retrieval engine from 1990 to August 14, 2013. Two independent reviewers critically reviewed the studies using preset inclusion and exclusion criteria. The quality of the eligible studies was assessed by the Cochrane 12-item scale. All included studies were summarized, and their data were extracted. Subgroup analyses were performed according to the different protocols of early functional rehabilitation. Nine studies, consisting of 6 randomized controlled trials and 3 quasi-randomized studies, were ultimately included. A total of 402 patients were identified. Six of the included studies utilized early weightbearing combined with early ankle motion exercises, while the other 3 only employed early ankle motion exercises. The subgroup analyses demonstrated that 11 of the 15 functional outcome measurements were significantly superior for patients who underwent both early weightbearing and ankle motion exercises than for those who underwent conventional cast immobilization. Similar rates of reruptures (odds ratio [OR], 1.36; 95% CI, 0.38-4.91; P = .64) and major complications (OR, 0.67; 95% CI, 0.24-1.87; P = .44) as well as a significantly lower rate of minor complications (OR, 0.51; 95% CI, 0.27-0.95; P = .03) were also observed in this early functional rehabilitation group. For the patients who solely performed early ankle motion exercises, only 2 of the 14

Previous animal studies showed contradictory clinical observations on whether acute hyperglycemia contributes to poor outcome in traumatic brain injury (TBI). Herein, we tried to clarify this issue. Striking with depths of 3.0-4.25mm at right occipitoparietal brain region and with depth of 3.75mm at right/left occipitoparietal or right/left frontoparietal brain region were performed, respectively. Blood glucose and insulin levels were traced every four hours from 1 to 72h after striking. HOMA2-%S and HOMA2-%β were calculated. Modified neurological severity scores (mNSS) were used to evaluate neurological deficit within 72h. Striking with depths of 3.5-4.25mm induced increase in blood glucose lasting up to 24h after striking. The levels of blood glucose after striking with depths of 3.75-4.25mm were significantly different from that of striking with the depth of 3.0mm. Striking with depth of 3.75mm at right/left occipitoparietal region induced higher blood glucose in 24h than that at right/left frontoparietal region. Insulin concentration increased slowly during 72h after striking. Striking also induced decrease in insulin sensitivity and secretion lasting 72h. Evaluation of mNSS revealed that severe striking (beyond 3.75mm) worsened nerve function than slight striking (<3.0mm). Intervention of acute hyperglycemia could decrease the mNSS from 2 to 7 days after TBI. Our results suggested that only severe TBI could induce acute hyperglycemia by itself, and early care of acute hyperglycemia could benefit the outcome of TBI patients. Copyright © 2016 Elsevier B.V.

Objective To investigate frequency, reasons, and factors associated with readmission to acute care (RTAC) during inpatient rehabilitation for traumatic brain injury (TBI). Design Prospective observational cohort. Setting Inpatient rehabilitation. Participants 2,130 consecutive admissions for TBI rehabilitation. Interventions Not applicable. Main Outcome Measure(s) RTAC incidence, RTAC causes, rehabilitation length of stay (RLOS), and rehabilitation discharge location. Results 183 participants (9%) experienced RTAC for a total 210 episodes. 161 patients experienced 1 RTAC episode, 17 had 2, and 5 had 3. Mean days from rehabilitation admission to first RTAC was 22 days (SD 22). Mean duration in acute care during RTAC was 7 days (SD 8). 84 participants (46%) had >1 RTAC episode for medical reasons, 102 (56%) had >1 RTAC for surgical reasons, and RTAC reason was unknown for 6 (3%) participants. Most common surgical RTAC reasons were: neurosurgical (65%), pulmonary (9%), infection (5%), and orthopedic (5%); most common medical reasons were infection (26%), neurologic (23%), and cardiac (12%). Older age, history of coronary artery disease, history of congestive heart failure, acute care diagnosis of depression, craniotomy or craniectomy during acute care, and presence of dysphagia at rehabilitation admission predicted patients with RTAC. RTAC was less likely for patients with higher admission Functional Independence Measure Motor scores and education less than high school diploma. RTAC occurrence during rehabilitation was significantly associated with longer RLOS and smaller likelihood of discharge home. Conclusion(s) Approximately 9% of patients with TBI experience RTAC during inpatient rehabilitation for various medical and surgical reasons. This information may help inform interventions aimed at reducing interruptions in rehabilitation due to RTAC. RTACs were associated with longer RLOS and discharge to an institutional setting.

Objectives Neurogranin (NRGN) is a small neuronal protein that plays an important role in synaptic signaling by regulating calmodulin (CaM) availability. In this study, we developed an ELISA to measure NRGN quantitatively in serum samples from a cohort of acute traumatic brain injury (TBI) patients and a non-TBI control cohort, and explored the potential value of NRGN as a circulating biomarker for TBI. Design and methods Recombinant His-NRGN protein was used to develop mouse monoclonal capture and rabbit polyclonal detection antibodies, and they were used to develop a sandwich ELISA. After validation, we used this ELISA to measure serum samples from a cohort of typical adult acute TBI patients (N = 76 TBI cases) and non-TBI control patients (N = 150 controls). Results The NRGN ELISA lower limit of detection was 0.055 ng/mL, lower limit of quantification was 0.2 ng/mL, and interassay CVs were ≤ 10.7%. The average recovery was 99.9% (range from 97.2–102%). Serum NRGN concentrations in TBI cases were significantly higher than in controls (median values were 0.18 ng/mL vs. 0.02 ng/mL, p < 0.0001), but did not discriminate TBI cases with intracranial hemorrhage (p = 0.09). Conclusions We have developed a highly sensitive and reproducible ELISA for measuring circulating NRGN in blood samples. Serum NRGN concentrations in acute TBI patients were significantly higher than in controls, indicating that NRGN could have utility as a circulating biomarker for acute TBI. This report provides evidence to support larger and controlled TBI clinical studies for NRGN validation and prediction of outcomes. PMID:26025774

Spontaneous perforation of pyometra is a rare entity with a reported incidence in the range of 0.01-0.05%. The clinical picture is similar to peritonitis arising from intestinal perforation and commonly the correct diagnosis is only made perioperatively. We report a case in an elderly postmenopausal woman presenting with an acute abdomen.

Previous studies reported discrepant white matter diffusivity in mild traumatic brain injury (mTBI) on the base of Glasgow Coma Scale, which are unreliable for some TBI severity indicators and the frequency of missing documentation in the medical record. In the present study, we adopted the Mayo classification system for TBI severity. In this system, the mTBI is also divided into two groups as “probable and symptomatic” TBI. We aimed to investigate altered microstructural integrity in symptomatic acute TBI (<1 week) by using tract-based spatial statics (TBSS) approach. A total of 12 patients and 13 healthy volunteers were involved and underwent MRI scans including conventional scan, and SWI and DTI. All the patients had no visible lesions by using conventional and SWI neuroimaging techniques, while showing widespread declines in the fractional anisotropy (FA) of gray matter and white matter throughout the TBSS skeleton, particularly in the limbic-subcortical structures. By contrast, symptomatic TBI patients showed no significant enhanced changes in FA compared to the healthy controls. A better understanding of the acute changes occurring following symptomatic TBI may increase our understanding of neuroplasticity and continuing degenerative change, which, in turn, may facilitate advances in management and intervention.

Previous studies have shown that administration of nicotinamide (Vitamin B(3)) in animal models of traumatic brain injury (TBI) and ischemia significantly reduced the size of infarction or injury and improved functional recovery. The present study evaluated the ability of nicotinamide to provide acute neuroprotection and edema reduction following TBI. Groups of rats were assigned to nicotinamide (500mg/kg) or saline (1.0ml/kg) treatment conditions and received contusion injuries or sham surgeries. Drug treatment was administered 15min following injury. Brains were harvested 24h later and either processed for histology or water content. Frozen sections were stained with the degenerating neuron stain (Fluoro-Jade B) (FJ) and cell counts were performed at the site of injury. Additional brains were processed for water content (a measure of injury-induced edema). Results of this study showed that administration of nicotinamide following TBI significantly reduced the number of FJ(+) neurons in the injured cortex compared to saline-treated animals. Examination of the water content of the brains also revealed that administration of nicotinamide significantly attenuated the amount of water compared to saline-treated animals in the injured cortex. These results indicate that nicotinamide administration significantly reduced neuronal death and attenuated cerebral edema following injury. The current findings suggest that nicotinamide significantly modulates acute pathophysiological processes following injury and that this may account for its beneficial effects on recovery of function following injury.

Objective EEG source localization is demonstrated in three cases of acute traumatic brain injury (TBI) with progressive lesion loads using anatomically faithful models of the head which account for pathology. Methods Multimodal magnetic resonance imaging (MRI) volumes were used to generate head models via the finite element method (FEM). A total of 25 tissue types—including 6 types accounting for pathology— were included. To determine the effects of TBI upon source localization accuracy, a minimum-norm operator was used to perform inverse localization and to determine the accuracy of the latter. Results The importance of using a more comprehensive number of tissue types is confirmed in both health and in TBI. Pathology omission is found to cause substantial inaccuracies in EEG forward matrix calculations, with lead field sensitivity being underestimated by as much as ~200% in (peri-) contusional regions when TBI-related changes are ignored. Failing to account for such conductivity changes is found to misestimate substantial localization error by up to 35 mm. Conclusions Changes in head conductivity profiles should be accounted for when performing EEG modeling in acute TBI. Significance Given the challenges of inverse localization in TBI, this framework can benefit neurotrauma patients by providing useful insights on pathophysiology. PMID:23746499

Diagnosis and management of peripheral nerve injury is complicated by the inability to assess microstructural features of injured nerve fibers via clinical examination and electrophysiology. Diffusion tensor imaging (DTI) has been shown to accurately detect nerve injury and regeneration in crush models of peripheral nerve injury, but no prior studies have been conducted on nerve transection, a surgical emergency that can lead to permanent weakness or paralysis. Acute sciatic nerve injuries were performed microsurgically to produce multiple grades of nerve transection in rats that were harvested 1 hour after surgery. High-resolution diffusion tensor images from ex vivo sciatic nerves were obtained using diffusion-weighted spin-echo acquisitions at 4.7 T. Fractional anisotropy was significantly reduced at the injury sites of transected rats compared with sham rats. Additionally, minor eigenvalues and radial diffusivity were profoundly elevated at all injury sites and were negatively correlated to the degree of injury. Diffusion tensor tractography showed discontinuities at all injury sites and significantly reduced continuous tract counts. These findings demonstrate that high-resolution DTI is a promising tool for acute diagnosis and grading of traumatic peripheral nerve injuries.

There is currently no effective medical treatment for traumatic brain injury (TBI). Beyond the immediate physical damage caused by the initial impact, additional damage evolves due to the inflammatory response that follows brain injury. Here we show that therapy with JM4, a low molecular weight 19-amino acid nonhematopoietic erythropoietin (EPO) peptidyl fragment, containing amino acids 28-46 derived from the first loop of EPO, markedly reduces acute brain injury. Mice underwent controlled cortical injury and received either whole molecule EPO, JM4, or sham-treatment with phosphate-buffered saline. Animals treated with JM4 peptide exhibited a large decrease in number of dead neural cells and a marked reduction in lesion size at both 3 and 8 days postinjury. Therapy with JM4 also led to improved functional recovery and we observed a treatment window for JM4 peptide that remained open for at least 9 h postinjury. The full-length EPO molecule was divided into a series of 6 contiguous peptide segments; the JM4-containing segment and the adjoining downstream region contained the bulk of the death attenuating effects seen with intact EPO molecule following TBI. These findings indicate that the JM4 molecule substantially blocks cell death and brain injury following acute brain trauma and, as such, presents an excellent opportunity to explore the therapeutic potential of a small-peptide EPO derivative in the medical treatment of TBI.

To evaluate whether diffusion tensor imaging (DTI) will noninvasively reveal white matter changes not present on conventional MRI in acute blast-related mild traumatic brain injury (mTBI) and to determine correlations with clinical measures and recovery. Prospective observational study of 95 US military service members with mTBI enrolled within 7 days from injury in Afghanistan and 101 healthy controls. Assessments included Rivermead Post-Concussion Symptoms Questionnaire (RPCSQ), Post-Traumatic Stress Disorder Checklist Military (PCLM), Beck Depression Inventory (BDI), Balance Error Scoring System (BESS), Automated Neuropsychological Assessment Metrics (ANAM), conventional MRI, and DTI. Significantly greater impairment was observed in participants with mTBI vs controls: RPCSQ (19.7 ± 12.9 vs 3.6 ± 7.1, p < 0.001), PCLM (32 ± 13.2 vs 20.9 ± 7.1, p < 0.001), BDI (7.4 ± 6.8 vs 2.5 ± 4.9, p < 0.001), and BESS (18.2 ± 8.4 vs 15.1 ± 8.3, p = 0.01). The largest effect size in ANAM performance decline was in simple reaction time (mTBI 74.5 ± 148.4 vs control -11 ± 46.6 milliseconds, p < 0.001). Fractional anisotropy was significantly reduced in mTBI compared with controls in the right superior longitudinal fasciculus (0.393 ± 0.022 vs 0.405 ± 0.023, p < 0.001). No abnormalities were detected with conventional MRI. Time to return to duty correlated with RPCSQ (r = 0.53, p < 0.001), ANAM simple reaction time decline (r = 0.49, p < 0.0001), PCLM (r = 0.47, p < 0.0001), and BDI (r = 0.36 p = 0.0005). Somatic, behavioral, and cognitive symptoms and performance deficits are substantially elevated in acute blast-related mTBI. Postconcussive symptoms and performance on measures of posttraumatic stress disorder, depression, and neurocognitive performance at initial presentation correlate with return-to-duty time.

Objective: To evaluate whether diffusion tensor imaging (DTI) will noninvasively reveal white matter changes not present on conventional MRI in acute blast-related mild traumatic brain injury (mTBI) and to determine correlations with clinical measures and recovery. Methods: Prospective observational study of 95 US military service members with mTBI enrolled within 7 days from injury in Afghanistan and 101 healthy controls. Assessments included Rivermead Post-Concussion Symptoms Questionnaire (RPCSQ), Post-Traumatic Stress Disorder Checklist Military (PCLM), Beck Depression Inventory (BDI), Balance Error Scoring System (BESS), Automated Neuropsychological Assessment Metrics (ANAM), conventional MRI, and DTI. Results: Significantly greater impairment was observed in participants with mTBI vs controls: RPCSQ (19.7 ± 12.9 vs 3.6 ± 7.1, p < 0.001), PCLM (32 ± 13.2 vs 20.9 ± 7.1, p < 0.001), BDI (7.4 ± 6.8 vs 2.5 ± 4.9, p < 0.001), and BESS (18.2 ± 8.4 vs 15.1 ± 8.3, p = 0.01). The largest effect size in ANAM performance decline was in simple reaction time (mTBI 74.5 ± 148.4 vs control −11 ± 46.6 milliseconds, p < 0.001). Fractional anisotropy was significantly reduced in mTBI compared with controls in the right superior longitudinal fasciculus (0.393 ± 0.022 vs 0.405 ± 0.023, p < 0.001).

Summary Background Distal bicep tendon injuries are a traumatic event though rather rare. The pathogenesis is not entirely clear. The most common cause for injury is an unexpected load on the biceps when the elbow is in an extended position. Although several studies have provided insight into the pathogenetic processes of the lesion, the literature suggests to treat all injuries surgically (whether partial or total) if there is high functional demand. Methods Between January 2006 and March 2016 were studied 20 patients surgically treated for a disconnected distal bicep, 15 with a total lesion and 5 with a partial lesion. The patients were divided into 2 groups. Surgical access with single incision was performed on 13 patients while a double surgical access was performed on 7 patients. The clinical and functional results were studied using an Ewald System Score (ESS). Results In both groups, the most rapid improvement was achieved for the parameters of pain and deformity with excellent results, while those of function and movement were normalized as gradual and progressive over next 2 months. Conclusion The clinical and functional outcomes during the follow-up examination after surgery showed excellent results in patients treated with both types of surgical procedures. PMID:28217566

Surgical treatment of an acute Achilles tendon rupture can effectively reduce the risk of re-rupture, but it increases the probability of surgical complications. We postulated that a minimally invasive surgical treatment might reduce the number of complications related to open surgery and improve the functional results. We enrolled 47 patients with acute Achilles tendon ruptures in a prospective, randomised trial to compare clinical results and complications between a minimally invasive procedure with the Achillon(®) device and traditional open surgery with Krackow-type sutures. The average patient age was 46 years. The follow up time was 24 months. No Achilles tendon re-rupture or nerve injury occurred in treated patients. There were two cases of wound infections in the open surgery group, and one superficial wound infection occurred in the minimally invasive group. The groups were not significantly different in the amount of pain, range of ankle movements, the single heel-rise test, calf circumference, or time to return to work and sports. After a two year follow-up period, we found no significant differences in clinical outcomes between groups treated with traditional open surgery or minimally invasive surgery.

Ventricular septal rupture (VSR) following myocardial infarction is a rare complication with high mortality. Although transcatheter closure has emerged as a less invasive method of VSR closure, the optimal timing and technique remain unclear. This is a single-center, retrospective, cohort study. Eleven patients that underwent transcatheter closure of post-AMI VSR from 2006 to 2013 at the Second Xiangya Hospital were included in this study. The clinical, procedural, and outcome data were analyzed. VSR occurred in 4 patients at anterior, 4 at posterior, and 3 at apical ventricular septum. Atrial Septal Defect occluder was used in 2 patients, muscular Ventricular Septal Defect occluder was used in 6 patients, and Patent Ductus Arteriosus occluder was used in 3 patients. The median time between VSR diagnosis and transcatheter closure was 18 days (range, 13-30 days). The median size of the VSR was 12 mm (range, 8-17 mm). The occlusion device was deployed successfully in 10 of 11 patients. Three patients died between zero and seven days after the procedure (30-day mortality, 27.3%). Eight patients survived during a follow-up of 150-1960 days. A follow-up TTE showed no residual shunt in three patients and a trivial or small residual shunt in five patients. Transcatheter closure of post-AMI VSR using Atrial Septal Defect, Ventricular Septal Defect, and Patent Ductus Arteriosus occluders is feasible and effective. If the clinical conditions permit, intervention can be delayed to the late phase (>2-3 weeks) after VSR diagnosis. Copyright © 2015. Published by Elsevier Ireland Ltd.

To evaluate all the possible therapeutic measures concerning the acute management of traumatic brain injury (TBI) mentioned in Cochrane Systematic Reviews published in the Cochrane Database of Systematic Reviews (CDSR). An exhausted literature search for all published Cochrane Systematic Reviews discussing therapeutic rather than prevention or rehabilitative interventions of TBI was conducted. We retrieved such databases as CDSR and Cochrane Injury Group, excluded the duplications, and eventually obtained 20 results, which stand for critical appraisal for as many as 20 different measures for TBI patients. The important data of each systematic review, including total population, intervention, outcome, etc, were collected and presented in a designed table. Besides, we also tried to find out the possible weakness of these clinical trials included in each review. Analysis of these reviews yielded meanfuling observations: (1) The effectiveness of most ordinary treatments in TBI is inconclusive except that corticosteroids are likely to be ineffective or harmful, and tranexamic acid, nimodipine and progesterone show a promising effect in bleeding trauma, traumatic subarachnoid hemorrhage, TBI or severe TBI. (2) A majority of the systematic reviews include a small number of clinical trials and the modest numbers of patients, largely due to the uncertainty of the effectiveness. (3) The quality of most trials reported in the systematic reviews is more or less questionable. (4) In addition, lots of other complex factors together may lead to the inconclusive results demonstrated in the Cochrane Systematic Reviews. For clinical physicians, to translate these conclusions into practice with caution is essential. Basic medication and nursing care deserve additional attention as well and can be beneficial. For researchers, high quality trials with perfect design and comprehensive consideration of various factors are urgently required.

Abstract Experimental traumatic brain injury (TBI) studies report the neuroprotective effects of female sex steroids on multiple mechanisms of injury, with the clinical assumption that women have hormonally mediated neuroprotection because of the endogenous presence of these hormones. Other literature indicates that testosterone may exacerbate injury. Further, stress hormone abnormalities that accompany critical illness may both amplify or blunt sex steroid levels. To better understand the role of sex steroid exposure in mediating TBI, we 1) characterized temporal profiles of serum gonadal and stress hormones in a population with severe TBI during the acute phases of their injury; and 2) used a biological systems approach to evaluate these hormones as biomarkers predicting global outcome. The study population was 117 adults (28 women; 89 men) with severe TBI. Serum samples (n=536) were collected for 7 days post-TBI for cortisol, progesterone, testosterone, estradiol, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). Hormone data were linked with clinical data, including acute care mortality and Glasgow Outcome Scale (GOS) scores at 6 months. Hormone levels after TBI were compared to those in healthy controls (n=14). Group based trajectory analysis (TRAJ) was used to develop temporal hormone profiles that delineate distinct subpopulations in the cohort. Structural equations models were used to determine inter-relationships between hormones and outcomes within a multivariate model. Compared to controls, acute serum hormone levels were significantly altered after severe TBI. Changes in the post-TBI adrenal response and peripheral aromatization influenced hormone TRAJ profiles and contributed to the abnormalities, including increased estradiol in men and increased testosterone in women. In addition to older age and greater injury severity, increased estradiol and testosterone levels over time were associated with increased mortality and worse global

To investigate whether the progressive recuperation of consciousness was associated with the reconsolidation of sleep and wake states in hospitalized patients with acute traumatic brain injury (TBI). This study comprised 30 hospitalized patients (age 29.1 ± 13.5 years) in the acute phase of moderate or severe TBI. Testing started 21.0 ± 13.7 days postinjury. Consciousness level and cognitive functioning were assessed daily with the Rancho Los Amigos scale of cognitive functioning (RLA). Sleep and wake cycle characteristics were estimated with continuous wrist actigraphy. Mixed model analyses were performed on 233 days with the RLA (fixed effect) and sleep-wake variables (random effects). Linear contrast analyses were performed in order to verify if consolidation of the sleep and wake states improved linearly with increasing RLA score. Associations were found between scores on the consciousness/cognitive functioning scale and measures of sleep-wake cycle consolidation (p < 0.001), nighttime sleep duration (p = 0.018), and nighttime fragmentation index (p < 0.001). These associations showed strong linear relationships (p < 0.01 for all), revealing that consciousness and cognition improved in parallel with sleep-wake quality. Consolidated 24-hour sleep-wake cycle occurred when patients were able to give context-appropriate, goal-directed responses. Our results showed that when the brain has not sufficiently recovered a certain level of consciousness, it is also unable to generate a 24-hour sleep-wake cycle and consolidated nighttime sleep. This study contributes to elucidating the pathophysiology of severe sleep-wake cycle alterations in the acute phase of moderate to severe TBI. © 2016 American Academy of Neurology.

Post-traumatic acute renal failure requiring renal replacement therapy in an intensive care unit (ICU) is associated with high mortality. To assess indicators of improved survival. This was a retrospective cohort study of 64 consecutive trauma patients (penetrating and blunt trauma and burns) who underwent haemodialysis (HD) over a period of 5 years. Information on pre-hospital and in-hospital resuscitation, trauma scores and physiological scores and daily ICU records were collected. The majority of the patients were dialysed with continuous venovenous haemofiltration in the early years of the study and later with sustained low-efficiency dialysis. Of the 64 patients 47 died, giving an overall mortality rate of 73%. Mortality was highest in the burns patients (84%). Survival in all patients, irrespective of injury, was unrelated to the Revised Trauma Score, Injury Severity Score, Acute Physiology and Chronic Health Evaluation Score or Trauma Injury Severity Score. The duration of HD did not differ significantly between the three trauma groups, and age was not a significant predictor of survival. Patients who were polyuric at the time of the initiation of HD had a lower mortality rate than those who were oliguric, anuric or normouric, although this did not reach statistical significance (p=0.09). Acute renal failure in trauma patients is associated with a low survival rate. Controversial conclusions have been presented in the literature. In this study, none of the parameters previously reported to affect survival proved to be valid, although the number of patients was comparable with those in other studies. Since understanding of the predictors and course of renal failure in trauma patients is still at an early stage, there is a need for multicentre prospective studies.

Mild traumatic brain injury is the most prevalent neurological insult and frequently results in neurobehavioural sequelae. However, little is known about the pathophysiology underlying the injury and how these injuries change as a function of time. Although diffusion tensor imaging holds promise for in vivo characterization of white matter pathology, both the direction and magnitude of anisotropic water diffusion abnormalities in axonal tracts are actively debated. The current study therefore represents both an independent replication effort (n = 28) of our previous findings (n = 22) of increased fractional anisotropy during semi-acute injury, as well as a prospective study (n = 26) on the putative recovery of diffusion abnormalities. Moreover, new analytical strategies were applied to capture spatially heterogeneous white matter injuries, which minimize implicit assumptions of uniform injury across diverse clinical presentations. Results indicate that whereas a general pattern of high anisotropic diffusion/low radial diffusivity was present in various white matter tracts in both the replication and original cohorts, this pattern was only consistently observed in the genu of the corpus callosum across both samples. Evidence for a greater number of localized clusters with increased anisotropic diffusion was identified across both cohorts at trend levels, confirming heterogeneity in white matter injury. Pooled analyses (50 patients; 50 controls) suggested that measures of diffusion within the genu were predictive of patient classification, albeit at very modest levels (71% accuracy). Finally, we observed evidence of recovery in lesion load in returning patients across a 4-month interval, which was correlated with a reduction in self-reported post-concussive symptomatology. In summary, the corpus callosum may serve as a common point of injury in mild traumatic brain injury secondary to anatomical (high frequency of long unmyelinated fibres) and biomechanics factors. A

Clinical and functional assessment of the surgical treatment for acute injury of the distal insertion of the biceps brachial performed with a surgical technique using a single incision in proximal forearm and fixation with suture anchors in the radial tuberosity. This study reviewed the medical records of patients who underwent surgical treatment of distal biceps injury during the period between January 2008 and July 2014. In a mean follow-up of 12 months, 22 patients with complete and acute injury, diagnosed through physical examination and imaging studies, were functionally assessed in the postoperative period regarding the range of motion (degrees of flexion-extension and pronation-supination), the presence of pain (VAS), the Andrews Carson-score, and the Mayo Elbow Performance Score (MEPS). During the postoperative follow-up assessment, no patient reported pain by VAS scale; all were satisfied with the esthetic appearance of the surgery. The range of articular movement remained unchanged at 95.4% of patients, with the loss of 8° of supination in one patient. No changes in muscle strength were observed. The results of the Andrews-Carson score were good in 4.6% and excellent in 95.4% of cases; the MEPS presented 100% of excellent results. The rate of complications was 27.2%, similar to the literature. Surgical repair of acute injury of the distal biceps trough a single incision in the proximal forearm and fixation with two suture anchors in the radial tuberosity is an effective and safe therapeutic option, allowing early motion and good functional results.

Few studies have used MRI to identify the ALL. As it was shown that it is not possible to precisely characterize this ligament in all examination, it is important to identify concomitant lesions that can help in diagnosing ALL abnormalities. It is important to characterise this injury due to its association with anterolateral knee instability. Thus, the present study was performed to determine the frequency of ALL injuries in patients with acute ACL rupture and to analyse its associated knee lesions. Patients with acute ACL injuries were evaluated by MRI. Among this population, the ALL was classified as non-visualised, injured or normal. The possible abnormalities of the meniscus, collateral ligaments, popliteus tendon, posterior cruciate ligament, Iliotibial band (ITB), anterolateral capsule and osseus injuries were evaluated. The association of an ALL injury with these other knee structures as well as sex and age was calculated. Among the 228 knees evaluated, the ALL could not be entirely identified in 61 (26.7%). Of the remaining 167, 66 (39.5%) presented an ALL abnormality and only four (6.1%) were Segond fractures. ALL abnormalities were associated with lesions of the lateral collateral ligament, medial collateral ligament, popliteus tendon, ITB, anterolateral capsule and osseous contusions of the femoral condyle and tibial plateau. No correlation was found with medial meniscus, lateral meniscus and posterior cruciate ligament injuries. There was no association between ALL injuries and gender, and older patients were more likely to present an ALL injury. ALL injuries are present in approximately 40% of ACL injuries, and a minority of these are Segond fractures. These injuries are associated with peripheral ligament injuries, anterolateral structures lesions and bone contusions, but there is no association with meniscal injuries. Surgeons must be aware of these associations to consider an ALL lesion even if it is not completely clear in imaging evaluation

An ideal surgical treatment of acute Achilles tendon rupture includes restoring the original length of the tendon, minimizing possible adhesions with the surrounding tissues, minimizing the risk of repeat rupture, alleviating wound problems, and providing an acceptable cosmetic outcome. In the mini-open repair technique, unlike the percutaneous repair technique, the quality of the tenodesis can be visualized without disturbing the healing potential of the surrounding tissues, thus minimizing wound problems. The purpose of the present study was to assess the long-term results of the mini-open repair technique in patients with acute Achilles tendon rupture. A total of 20 consecutive patients with acute Achilles tendon rupture, admitted to our inpatient clinic from October 2003 to March 2008, were included in the present study. The patients underwent Achilles tenodesis with the mini-open repair technique, and each patient was followed up for 5 years. The study was completed in April 2013. The surgical procedure was performed with the assistance of a device designed in our orthosis laboratories, similarly to that defined by Assal et al. Of the 20 patients, 18 were male and 2 were female. Their mean age was 39.3 (range 21 to 55) years. The Achilles tendon rupture was located on the left side in 15 patients (75%) and on the right side in 5 patients (25%). The mean follow-up duration was 58.5 (range 18 to 60) months and no complications occurred during the follow-up period, including repeat rupture, wound site infection, and sural nerve injury. The mean American Orthopaedic Foot and Ankle Society scale score for the patients was 99.2 (range 94 to 100) points at the final follow-up visit. All our patients were able to return to work and sporting activities. According to the Trillat scores, the outcome was excellent in 19 patients and good in 1 patient at the 18th postoperative month. No complaint, such as pain or loss of function, that might have a negative effect on the

Background Acute traumatic tendon injuries of the hand and wrist are commonly encountered in the emergency department. Despite the frequency, few studies have examined the true incidence of acute traumatic tendon injuries in the hand and wrist or compared the incidences of both extensor and flexor tendon injuries. Methods We performed a retrospective population-based cohort study of all acute traumatic tendon injuries of the hand and wrist in a mixed urban and rural Midwest county in the United States between 2001-2010. A regional epidemiologic database and medical codes were used to identify index cases. Epidemiologic information including occupation, year of injury, mechanism of injury and the injured tendon and zone were recorded. Results During the 10-year study period there was an incidence rate of 33.2 injuries per 100,000 person-years. There was a decreasing rate of injury during the study period. Highest incidence of injury occurred at 20-29 years of age. There was significant association between injury rate and age, and males had a higher incidence than females. The majority of cases involved a single tendon, with extensor tendon injuries occurring more frequently than flexor tendons. Typically, extensor tendon injuries involved zone three of the index finger, while flexor tendons involved zone two of the index finger. Work-related injuries accounted for 24.9% of acute traumatic tendon injuries. The occupations of work-related injuries were assigned to major groups defined by the 2010 Standard Occupational Classification structure. After assigning these patients' occupations to respective major groups, the most common groups work-related injuries occurred in construction and extraction occupations (44.2%), food preparation and serving related occupations (14.4%), and transportation and material moving occupations (12.5%). Conclusions Epidemiology data enhances our knowledge of injury patterns and may play a role in the prevention and treatment of future

Traumatic blunt cardiac injuries have a high mortality rate, and prompt diagnosis and treatment can be lifesaving in cardiac tamponade. A 62-year-old man was transferred to the emergency department after a motor vehicle accident. He was hemodynamically unstable. A focused assessment with sonography in trauma (FAST) showed pericardial fluid with right ventricular collapse consistent with cardiac tamponade in the subxiphoid view. He collapsed despite a subxiphoid pericardiotomy. Owing to the ongoing hemodynamic instability, we performed a left anterolateral thoracotomy. Direct incision of the pericardium showed blood and clots within the pericardial space, indicating hemopericardium. The heart stroke and hemodynamic status recovered on removing the clot. Although the physical findings of cardiac tamponade are not always apparent in life-threatening acute cardiac tamponade after blunt trauma, FAST is a reliable tool for diagnosing and following cardiac tamponade. A median sternotomy is a standard approach for evaluating cardiac injury in hemodynamically stable patients with or without cardiopulmonary bypass. However, a left anterior thoracotomy was the fastest, simplest life-saving procedure considering the need for open-chest cardiac massage given our patient's life-threatening condition. A prompt diagnosis using FAST and treatment can be lifesaving in traumatic acute cardiac tamponade. A pericardiotomy via a thoracotomy is mandatory for lifesaving cardiac decompression in acute traumatic cardiac tamponade in cases of ineffective drainage due to clot formation within the pericardial space.

Acute Achilles tendon rupture (AATR) is a frequent injury occurring dominantly in young to middle-aged males. Outcomes and complications between percutaneous and open repair are still controversial. Thus, the purpose of this meta-analysis is to evaluate the outcomes and complications of these two operative methods. We searched multiple databases: PubMed, Web of Science, EMBASE and the Cochrane Library up to October 2016. Two reviewers independently screened the studies for eligibility, evaluated the quality and extracted data from eligible studies, with confirmation by cross-checking. The major results and conclusions were concluded, and the different complication rates and functional outcomes were compared. Meta-analysis was processed by Rev Man 5.3 software. Five randomized controlled trials (RCTs) and seven retrospective cohort studies involving 815 patients met the inclusion criteria. The sural nerve injury rate in the percutaneous group was significantly higher (RR = 3.52, 95%CI 1.45 to 8.57, P = 0.006). However, deep infection rate in the open group was higher (RR = 0.33, 95%CI 0.11 to 0.96, P = 0.04) and subgroup analysis of five RCTs showed no significant difference (RR = 0.42, 95%CI 0.09 to 2.10, P = 0.29). No significant difference was seen regarding the rate of re-rupture. The time of operation in the percutaneous group was shorter (RR = -1.99, 95%CI -3.81 to -0.80, P = 0.001). American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score showed statistically different in the two groups. Other functional outcomes were similar in the two groups. Percutaneous repair has the advantages of operation time, deep infection and AOFAS score. The functional outcomes were similar in two treatment groups except AOFAS score. Despite the higher incidence of sural nerve injury, we still believe that percutaneous repair is superior to open repair for treating AATR. Copyright © 2017. Published by Elsevier Ltd.

Prospective, population-based study. This paper is part of the Stockholm Thessaloniki Acute Traumatic Spinal Cord Injury Study (STATSCIS). To characterize patient populations and to compare acute management after traumatic spinal cord injury (TSCI). The Greater Thessaloniki region in Greece and the Greater Stockholm region in Sweden. Inception cohorts with acute TSCI that were hospitalized during the study period, that is September 2006 to October 2007, were identified. Overall, 81 out of 87 cases consented to inclusion in Thessaloniki and 47 out of 49 in Stockholm. Data from Thessaloniki were collected through physical examinations, medical record reviews and communication with TSCI cases and medical teams. Data from Stockholm were retrieved from the Nordic Spinal Cord Injury Registry. There were no significant differences between study groups with regard to core clinical characteristics. In contrast, there were significant differences in (1) transfer logistics from the scene of trauma to a tertiary-level hospital (number of intermediate admissions, modes of transportation and duration of transfer) and (2) acute key therapeutic interventions, that is, the use of mechanical ventilation (49% in Thessaloniki versus 20% in Stockholm), and performance of tracheostomy (36% in Thessaloniki versus 15% in Stockholm); spinal surgery was performed significantly more often and earlier in Stockholm than in Thessaloniki. Despite largely similar core clinical characteristics, Stockholm and Thessaloniki cases underwent significantly different acute management, most probably to be attributed to adaptations to the differing regional approaches of care one following a systematic approach of SCI care and the other not.

We present a case of traumatic vertical atlantoaxial dislocation of 16 millimetres with a fatal outcome. We hypothesize that this extremely rare traumatic vertical atlantoaxial dislocation results from insufficiency of the C1/C2 facet capsules after rupture of the tectorial membrane and the alar ligaments.

Objective The purpose of this study was to investigate the impact of continuous renal replacement therapy (CRRT) on survival and relevant factors in patients who underwent CRRT after traumatic brain injury (TBI). Methods We retrospectively reviewed the laboratory, clinical, and radiological data of 29 patients who underwent CRRT among 1,190 TBI patients treated at our institution between April 2011 and June 2015. There were 20 men and 9 women, and the mean age was 60.2 years. The mean initial Glasgow Coma Scale score was 9.2, and the mean injury severity score was 24. Kaplan-Meier method and Cox regression were used for analysis of survival and relevant factors. Results The actuarial median survival time of the 29 patients was 163 days (range, 3-317). Among the above 29 patients, 22 died with a median survival time of 8 days (range, 3-55). The causes of death were TBI-related in 8, sepsis due to pneumonia or acute respiratory distress syndrome (ARDS) in 4, and multi-organ failure in 10. Among the various factors, urine quantity of more than 500 mL for 24-hours before receiving CRRT was a significant and favorable factor for survival in the multivariate analysis (p=0.026). Conclusion According to our results, we suggest that early intervention with CRRT may be beneficial in the treatment of TBI patients with impending acute renal failure (ARF). To define the therapeutic advantages of early CRRT in the TBI patients with ARF, a well-designed and controlled study with more cases is required. PMID:27857914

Objective Develop a non-terminal animal model of acute joint injury that demonstrates clinical and morphological evidence of early post-traumatic osteoarthritis (PTOA). Methods An osteochondral (OC) fragment was created arthroscopically in one metacarpophalangeal (MCP) joint of 11 horses and the contralateral joint was sham operated. Eleven additional horses served as unoperated controls. Every 2 weeks, force plate analysis, flexion response, joint circumference, and synovial effusion scores were recorded. At weeks 0 and 16, radiographs (all horses) and arthroscopic videos (OC injured and sham joints) were graded. At week 16, synovium and cartilage biopsies were taken arthroscopically from OC injured and sham joints for histologic evaluation and the OC fragment was removed. Results Osteochondral fragments were successfully created and horses were free of clinical lameness after fragment removal. Forelimb gait asymmetry was observed at week 2 (P=0.0012), while joint circumference (P<0.0001) and effusion scores (P<0.0001) were increased in injured limbs compared to baseline from weeks 2 to 16. Positive flexion response of injured limbs was noted at multiple time points. Capsular enthesophytes were seen radiographically in injured limbs. Articular cartilage damage was demonstrated arthroscopically as mild wear-lines and histologically as superficial zone chondrocyte death accompanied by mild proliferation. Synovial hyperemia and fibrosis were present at the site of OC injury. Conclusion Acute OC injury to the MCP joint resulted in clinical, imaging, and histologic changes in cartilage and synovium characteristic of early PTOA. This model will be useful for defining biomarkers of early osteoarthritis and for monitoring response to therapy and surgery. PMID:23467035

Introduction: Traumatic brain injury (TBI) is an under-recognized cause of hypopituitarism. According to recent data, it could be more frequent than previously known. However, there is a scarcity of data in Indian population. Aims: The main aim of the study was to determine the prevalence of pituitary hormone deficiencies in the acute phase of TBI. The secondary objectives were to correlate the severity of trauma with basal hormone levels and to determine whether initial hormone deficiencies predict mortality. Subjects and Methods: Forty-nine TBI patients (41 men and 8 women) were included in this study. Pituitary functions were evaluated within 24 h of admission. Results: Gonadotropin deficiency was found in 65.3% patient while 46.9% had low insulin-like growth factor-1, 12.24% had cortisol level <7 mcg/dl. Cortisol and prolactin level were positively correlated with the severity of TBI suggestive of stress response. Free triiodothyronine (fT3) and free thyroxine were significantly lower in patients with increasing severity of tuberculosis. Logistic regression analysis revealed that mortality after TBI was unrelated to the basal pituitary hormone levels except low T3 level, which was found to be positively related to mortality. Conclusions: Pituitary dysfunction is common after TBI and the most commonly affected axes are growth hormone and gonadotropin axis. Low fT3 correlates best with mortality. During the acute phase of TBI, at least an assessment of cortisol is vital as undetected cortisol deficiency can be life-threatening PMID:28217503

Although the pre-surgical management of patients with acute traumatic subdural hematoma prioritizes rapid transport to the operating room, there is conflicting evidence regarding the importance of time interval from injury to surgery with regards to outcomes. We sought to determine the association of surgical timing with outcomes for subdural hematoma. A retrospective review was performed of 522 consecutive patients admitted to a single center from 2006-2012 who underwent emergent craniectomy for acute subdural hematoma. After excluding patients with unknown time of injury, penetrating trauma, concurrent cerebrovascular injury, epidural hematoma, or intraparenchymal hemorrhage greater than 30 mL, there remained 45 patients identified for analysis. Using a multiple regression model, we examined the effect of surgical timing, in addition to other variables on in-hospital mortality (primary outcome), as well as the need for tracheostomy or gastrostomy (secondary outcome). We found that increasing injury severity score (odds ratio [OR] 1.146; 95% confidence interval [CI] 1.035-1.270; p=0.009) and age (OR1.066; 95%CI 1.006-1.129; p=0.031) were associated with in-hospital mortality in multivariate analysis. In this model, increasing time to surgery was not associated with mortality, and in fact had a significant effect in decreasing mortality (OR 0.984; 95%CI 0.971-0.997; p=0.018). Premorbid aspirin use was associated with a paradoxical decrease in mortality (OR 0.019; 95%CI 0.001-0.392; p=0.010). In this patient sample, shorter time interval from injury to surgery was not associated with better outcomes. While there are potential confounding factors, these findings support the evaluation of rigorous preoperative resuscitation as a priority in future study.

ABSTRACT Background: Acute coagulopathy after traumatic brain injury (TBI) involves a complex multifactorial hemostatic response that is poorly characterized. Objectives: To examine early posttraumatic alterations in coagulofibrinolytic, endothelial, and inflammatory blood biomarkers in relation to sympathetic nervous system (SNS) activation and 6-month patient outcomes, using multivariate partial least-squares (PLS) analysis. Patients and Methods: A multicenter observational study of 159 adult isolated TBI patients admitted to the emergency department at an urban level I trauma center, was performed. Plasma concentrations of 6 coagulofibrinolytic, 10 vascular endothelial, 19 inflammatory, and 2 catecholamine biomarkers were measured by immunoassay on admission and 24 h postinjury. Neurological outcome at 6 months was assessed using the Extended Glasgow Outcome Scale. PLS-discriminant analysis was used to identify salient biomarker contributions to unfavorable outcome, whereas PLS regression analysis was used to evaluate the covariance between SNS correlates (catecholamines) and biomarkers of coagulopathy, endotheliopathy, and inflammation. Results: Biomarker profiles in patients with an unfavorable outcome displayed procoagulation, hyperfibrinolysis, glycocalyx and endothelial damage, vasculature activation, and inflammation. A strong covariant relationship was evident between catecholamines and biomarkers of coagulopathy, endotheliopathy, and inflammation at both admission and 24 h postinjury. Conclusions: Biomarkers of coagulopathy and endotheliopathy are associated with poor outcome after TBI. Catecholamine levels were highly correlated with endotheliopathy and coagulopathy markers within the first 24 h after injury. Further research is warranted to characterize the pathogenic role of SNS-mediated hemostatic alterations in isolated TBI. PMID:27206278

Acute traumatic transection of the aorta (ATAT) is a devastating event. Transluminal endovascular aortic repair (TEVAR) has meanwhile become an excellent alternative for such lesions. A 27-year old woman sustained a multiple trauma in a car accident including ATAT which was treated by aortic stent graft placement. Six years after the endovascular repair, our patient had only noticed, just shortly after an annual computed tomography (CT) check-up, that she was pregnant and in the 9th week of gestation. The CT was considered as unproblematic for the foetus since direct radiation of the uterus had been avoided. Our patient clearly preferred a vaginal delivery over a caesarean section. The pregnancy was uneventful with uncomplicated vaginal delivery at term. This case shows that vaginal delivery is possible if the stent graft is in regular position without signs of endoleaks and the rest of the aorta is free from dissection or aneurysm formation. It indicates that TEVAR is a sound and durable treatment modality in ATATs and that aortic stent grafts can resist increased intravascular volume and elevated aortic pressure levels as encountered in pregnancy and during vaginal delivery. This particular case also shows that it is possible to respect a patient's right of self-determination.

Acute compartment syndrome of the lower leg and foot is a not widely reported, but serious, potential complication that can develop after fractures, crush injuries, or high-velocity trauma of the lower extremity. Early recognition and treatment are critical in preventing morbidity and permanent complications. Although compartment syndrome of the lower leg and foot has been well-studied and documented in adults, its occurrence in the pediatric population is rare. We performed a systematic review of the published data and present the case of the youngest patient with isolated ACS of the foot. A high index of suspicion is warranted in pediatric patients with a traumatic injury to the lower extremity for compartment syndrome. Inconclusive radiographic findings owing to skeletal immaturity and the inability to verbalize symptoms place young children at high risk of undiagnosed compartment syndrome. Clinicians should have a very low threshold for fasciotomy to prevent long-term sequelae associated with undiagnosed compartment syndrome.

The most appropriate operative treatment of acute midsubstance Achilles tendon ruptures is controversial. One approach uses a mini-open, device-assisted suture system (Achillon(®) System(™), Integra LifeSciences Corp, Plainsboro, NJ) that has been generally available since 2002. To date, the incidence of complications with this system has not yet been evaluated. Therefore, we conducted a systematic review of electronic databases and relevant peer-reviewed sources as outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for the preparation of systematic reviews. Studies that reported acute (injury to surgery interval ≤ 10 days) midsubstance Achilles tendon ruptures repaired with the Achillon(®) mini-open suture system, provided a detailed description of all complications encountered, and a mean follow-up period of 12 months or more and 15 repairs or more were included. A total of 33 studies were identified, of which 8 (24%) met our inclusion criteria involving 253 repairs. Four studies were prospective and involved 169 repairs. The weighted mean age for the entire cohort was 39.5 (range 22 to 82) years, and the weighted mean follow-up period was 19.2 (range 5 to 44) months. The incidence of complications was 8.3% (21 of 253) and included 8 (3.2%) repeat ruptures, 5 (2%) incision problems, 3 (1.2%) sural nerve injuries, 3 (1.2%) suture reactions or irritations, and 2 (0.8%) infections. Our systematic review revealed that this mini-open, device-assisted suture system provides a safe and reproducible technique to repair acute midsubstance Achilles tendon ruptures with an acceptable incidence of complications.

Ventricular septal rupture (VSR) is a rare but devastating complication after acute myocardial infarction (AMI). While the incidence has decreased, the mortality rate from VSR has remained extremely high. The use of mechanical circulatory support with intra-aortic balloon pump (IABP) and extracorporal membrane oxygenation (ECMO) may be useful in providing hemodynamic stability and time for myocardial scarring. However, the optimal timing for surgical repair remains an enigma. Retrospective analysis of 14 consecutive patients diagnosed with VSR after AMI at Montefiore Medical Center between January 2009 and June 2015. A chart review was performed with analysis of baseline characteristics, hemodynamics, imaging, percutaneous interventions, surgical timing, and outcomes. The survival group had a higher systolic BP (145 vs 98, p<0.01), higher MAP (96 vs 76, p=0.03), and lower HR (75 vs 104, p=0.05). Overall surgical timing was 6.5 ± 3.7 days after indexed myocardial infarction with a significant difference between survivors and non-survivors (9.8 vs 4.3, p=0.01). The number of pre-operative days using IABP was longer in survivors (6.5 vs 3.2, p=0.36) as was post-operative ECMO use (4.5 vs 2 days, p=0.35). The overall 30-day mortality was 71.4% with a 60% surgical mortality rate. Hemodynamics at the time of presentation and a delayed surgical approach of at least 9 days showed significant association with improved survival. Percutaneous coronary intervention (PCI) was more common in non-survivors. The use of IABP in the pre-operative period and post-operative ECMO use likely provide a survival benefit. PMID:27073732

To characterize the natural course of traumatic intraparenchymal contusions and hematomas (IPHs) and to identify risk factors for IPH progression in the acute post-injury period. A retrospective analysis was performed on a prospective observational database containing 113 head trauma patients exhibiting 229 initially nonoperated acute IPHs. The main outcome variable was radiographic evidence of IPH progression on serially obtained head computed tomographic (CT) scans. Secondary outcomes included the actual amount of IPH growth and later surgical evacuation. Univariate and multivariate analyses (using a generalized estimate equation) were applied to both demographic and initial radiographic features to identify risk factors for IPH progression and surgery. Overall, 10 IPHs (4%) shrank, 133 (58%) remained unchanged, and 86 (38%) grew between the first and second head CT scan. IPH progression was independently associated with the presence of subarachnoid hemorrhage (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.12-2.3), presence of a subdural hematoma (OR, 1.94; 95% CI, 1.1-3.43), and initial size (OR, 1.11; 95% CI, 1.02-1.21, for each cm volume). Size of initial IPH proportionately correlated with the amount of subsequent growth (linear regression, P < 0.001). Worsened Glasgow Coma Score between initial and follow-up head CT scan (OR, 8.6; 95% CI, 1.5-50), IPH growth greater than 5 cm (OR, 7.3; 95% CI, 1.6-34), and effacement of basal cisterns on initial CT scan (OR, 9.0; 95% CI, 1.5-52) were strongly associated with late surgical evacuation. A large proportion of IPHs progress in the acute post-injury period. IPHs associated with subarachnoid hemorrhage, a subdural hematoma, or large initial size should be monitored carefully for progression with repeat head CT imaging. Effacement of cisterns on the initial head CT scan was strongly predictive of failure of nonoperative management, thereby leading to surgical evacuation. These findings should be important

Resolution of a traumatic acute subdural haematoma (ASDH) requires weeks or months. However, cases of rapid spontaneous resolution of ASDH within 72 hours after trauma have been reported. The purpose of this study was to obtain a better understanding of the clinical and CT features of cases of rapid resolution following traumatic ASDH. Between 2011-2014, the authors retrospectively collected data from 14 patients with rapid resolution of traumatic ASDH. The clinical data and CT findings of these cases were collected and analysed. In 13 of the 14 patients, there was a rapid spontaneous resolution of the ASDH within 48 hours. The mean haematoma width of the second CT was significantly smaller than the width of the initial CT. A significantly marked resolution of the midline shift was observed in the second CT in all patients. The outcome was good in the majority of patients. The acute fluctuation of ICP may drive the spontaneous rapid resolution and redistribution of ASDH. Patients with abnormal coagulant function may be more likely to experience rapid resolution of ASDH. A band of low density in the initial CT image may be a useful sign for rapid resolution of ASDH.

Following traumatic brain injury, both sleep dysfunction and cognitive impairment are common. Unfortunately, little is known regarding the potential associations between these 2 symptoms during acute recovery. This study sought to prospectively examine the relationship between ratings of sleep dysfunction and serial cognitive assessments among traumatic brain injury acute neurorehabilitation admissions. Participants were consecutive admissions to a free-standing rehabilitation hospital following moderate to severe traumatic brain injury (Median Emergency Department Glasgow Coma Scale = 7). Participants were assessed for sleep-wake cycle disturbance (SWCD) and cognitive functioning at admission and with subsequent weekly examinations. Participants were grouped on the basis of presence (SWCD+) or absence (SWCD-) of sleep dysfunction for each examination; groups were equivalent on demographic and injury variables. Individual Growth Curve modeling was used to examine course of Cognitive Test for Delirium performance across examinations. Individual Growth Curve modeling revealed a significant interaction between examination number (ie, time) and SWCD group (β = -4.03, P < .001) on total Cognitive Test for Delirium score. The SWCD+ ratings on later examinations were predicted to result in lower Cognitive Test for Delirium scores and greater cognitive impairment over time. This study has implications for improving neurorehabilitation treatment, as targeting sleep dysfunction for early intervention may facilitate cognitive recovery.

Objective To assess the effect of timing and techniques of tracheostomy on morbidity, mortality, and the burden of resources in patients with acute traumatic spinal cord injuries (SCIs) undergoing mechanical ventilation. Design Review of a prospectively collected database. Setting Intensive and intermediate care units of a monographic hospital for the treatment of SCI. Participants Consecutive patients admitted to the intensive care unit (ICU) during their first inpatient rehabilitation for cervical and thoracic traumatic SCI. A total of 323 patients were included: 297 required mechanical ventilation and 215 underwent tracheostomy. Outcome measures Demographic data, data relevant to the patients’ neurological injuries (level and grade of spinal cord damage), tracheostomy technique and timing, duration of mechanical ventilation, length of stay at ICU, incidence of pneumonia, incidence of perioperative and early postoperative complications, and mortality. Results Early tracheostomy (<7 days after orotracheal intubation) tracheostomy was performed in 101 patients (47%) and late (≥7 days) in 114 (53%). Surgical tracheostomy was employed in 119 cases (55%) and percutaneous tracheostomy in 96 (45%). There were 61 complications in 53 patients related to all tracheostomy procedures. Two were qualified as serious (tracheoesophageal fistula and mediastinal abscess). Other complications were mild. Bleeding was moderate in one case (late, percutaneous tracheostomy). Postoperative infection rate was low. Mortality of all causes was also low. Conclusion Early tracheostomy may have favorable effects in patients with acute traumatic SC. Both techniques, percutaneous and surgical tracheostomy, can be performed safely in the ICU. PMID:21528630

We report the case of a 56 years old male patient, smoker, obese, with untreated arterial hypertension, hospitalized on 16.02.07 with the diagnosis of inferior acute myocardial infarction, for which he received thrombolysis with streptokinase, followed by anticoagulation with non fractioned heparin. Two days later he started to complain of acute abdominal pain, and laboratory findings showed a low hemoglobin level. Imaging findings (ultrasonography and CT scan) showed evidence of subcapsular liver haematoma, caused by bleeding at hepatic and splenic level. He received red blood packed cells, fresh frozen plasma, cryoprecipitate, activated factor VII and was transferred by helicopter to Fundeni Clinical Institute--Intensive care unit (ICU). On admission, the patient was conscious, anxious, dyspneic, with mild hypoxia, with no signs of low cardiac output and with a painful abdomen. ECG, echocardiography and elevated myocardial necrosis enzymes confirmed myocardial infarction. Shortly after admission there was a worsening of his clinical condition, with a decrease in hemoglobin level despite red blood packed cells administration (Hb=7.8 g/dl) and thrombocytopenia (82000/mmc), with normal coagulation tests, thus suggesting active intraabdominal bleeding. Echography and CT scan confirmed bleeding. Emergency surgery was performed, showing massive haemoperitoneum (approx 4.5 L of blood), due to spontaneous rupture of a subcapsular hematoma in the liver. The surgical hemostasis was performed on the liver parenchyma laceration. Duration of surgery was 4 hours. There were no significant cardiac events during surgery (no signs of ischemia on ECG, no ST elevation), despite the need for inotropic agent. After surgery, the patient was referred to the ICU, intubated and ventilated, with inotropic support - dobutamine. Sequential ECG's, enzymatic trend and echocardiographies were performed to monitor myocardial ischemia. The outcome was favourable, no further bleeding and no

Recent studies have shown that the decrease in ventricular septal rupture (VSR) incidence after acute myocardial infarction is related to the improvement of reperfusion strategies. Our main objective was to explore the influence of therapeutic management changes on post-infarct VSR patient outcomes in a single reference center over a period of 30 years. We analyzed therapeutic management strategies and mortality rates in 228 patients with VSR after acute myocardial infarction admitted from 1981 to 2010. Patients were classified in 3 successive decades. There were no significant differences in clinical characteristics of patients with VSR at admission among those decades. Overall, surgery was performed in 159 patients (71.9%), primary transcatheter VSR closure was attempted in 5 patients (2.2%), and 64 patients (27.6%) were managed medically. Independent predictors of in-hospital mortality were VSR surgical repair (odds ratio [OR] 0.22, 95% confidence interval [CI] 0.1 to 0.7, p = 0.008), cardiogenic shock (OR 6.06, 95% CI 2.8 to 13.1, p <0.0001), and Killip class on admission (OR 1.75, 95% CI 1.1 to 9.9, p = 0.02). We found a significant 1-year mortality reduction between the first and second decades (hazard ratio 0.48, 95% CI 0.28 to 0.80; p = 0.005), with no significant change in the last decade (p = 0.2). This change was related to a systematic referral to surgical repair and shorter delays to VSR surgery (5.2 ± 6.3 vs 1.9 ± 3.2 days from first to second decade; p = 0.012). In conclusion, surgical repair remains the only significant efficient therapy to reduce mortality in patients with VSR (p <10(-3)). In-hospital prognosis remains disappointing. This contrasts with the favorable long-term outcome of patients who survive the perioperative period and are discharged from hospital. Copyright © 2013 Elsevier Inc. All rights reserved.

A 65-year-old female presented with an extremely rare case of a ruptured thrombosed large aneurysm of the anterior inferior cerebellar artery (AICA) in which a local hematoma compressed the medulla oblongata and caused acute respiratory failure. She first presented with dizziness, general fatigue, and nausea 2 months before admission. She was hospitalized for intense general fatigue, nausea, and occipitalgia. Computed tomography and T(1)-weighted magnetic resonance imaging showed a heterogeneous lesion around the right cerebello-medullary cistern. Angiography revealed a fusiform aneurysm of the right AICA. Asphyxia occurred 4 days after admission and the patient underwent an emergency operation. No subarachnoid hematoma was present, but a hematoma around the ruptured portion markedly compressed the medulla oblongata. The medulla oblongata was adequately decompressed after subtotal removal of the aneurysm. The patient's respiratory status and consciousness level recovered after the operation.

Pancreaticoduodenal artery (PDA) aneurysm is a rare but clinically important form of vascular disease. A small proportion of these aneurysms are caused by compression of the artery by the median arcuate ligament (MAL). The objective of the study was to establish whether it is feasible and effective to treat ruptured PDA aneurysms without treating the celiac stenosis caused by the MAL. From January 2007 to November 2014, 10 patients were included. Standard embolization or surgical procedures were used to treat the ruptured aneurysms, but the celiac stenosis itself was not treated. The primary end point was the feasibility and efficacy of embolization for the treatment of ruptured PDA aneurysms. The secondary end points included clinical data, imaging findings, the success rate of embolization and the outcome during follow up. All patients presented with acute, non-specific epigastric pain with nausea. An abdominal computed tomography scan revealed peri-pancreatic hematoma in all cases, and PDA aneurysms were visible in six patients. The aneurysms ranged from 2 mm to 10 mm in diameter and were variously located on the anterior PDA (n = 1), the posterior PDA (n = 3), and the branch of the dorsal pancreatic artery (n = 6). Surgery was performed in two cases (with one death). Embolization was successful in the other eight cases. The median length of hospital stay was 10 days (range 8-25 days). Over a median follow up period of 11 months (range 5-48 months), none of the PDA aneurysms recurred. Rupture of a PDA aneurysm caused by the MAL should always be considered in the differential diagnosis of acute abdominal pain, because the condition requires specific management. Embolization is safe and has a high success rate. Surgery should only be performed when embolization fails. Copyright © 2015 European Society for Vascular Surgery. Published by Elsevier Ltd.

Introduction Spontaneous bladder rupture is a rare and serious event with high mortality. It is not often considered in the patient presenting with peritonitis. This often leads to delays in diagnosis. There are very few case reports of true spontaneous rupture in the literature. This is the first such reported case in which bladder rupture was attributable to neurogenic bladder dysfunction following a stroke. Case presentation We report the case of a 67-year-old Caucasian man who presented with lower abdominal pain and a peritonitic abdomen. He had a long-term urethral catheter because of urinary retention following a previous stroke. He was treated conservatively with antibiotics before a surgical opinion was sought. Exploratory laparotomy confirmed the diagnosis of spontaneous bladder rupture. After repair of the defect, he eventually made a full recovery. Conclusion In this unusual case report, we describe an example of a serious event in which delays in diagnosis may lead to increased morbidity and mortality. To date, no unifying theory explaining why rupture occurs has been postulated. We conducted a thorough literature search to examine the etiological factors in other published cases. These etiological factors either increase intra-vesical pressure or decrease the strength of the bladder wall. We hope that by increasing awareness of these etiological factors, spontaneous bladder rupture may be diagnosed earlier and appropriate therapy started. PMID:21714888

Abstract Traumatic brain injury (TBI) represents a leading cause of death and disability among young persons with ∼1.7 million reported cases in the United States annually. Although acute alcohol intoxication (AAI) is frequently present at the time of TBI, conflicting animal and clinical reports have failed to establish whether AAI significantly impacts short-term outcomes after TBI. The objective of this study was to determine whether AAI at the time of TBI aggravates neurobehavioral outcomes and neuroinflammatory sequelae post-TBI. Adult male Sprague-Dawley rats were surgically instrumented with gastric and vascular catheters before a left lateral craniotomy. After recovery, rats received either a primed constant intragastric alcohol infusion (2.5 g/kg+0.3 g/kg/h for 15 h) or isocaloric/isovolumic dextrose infusion followed by a lateral fluid percussion TBI (∼1.4 J, ∼30 ms). TBI induced apnea and a delay in righting reflex. AAI at the time of injury increased the TBI induced delay in righting reflex without altering apnea duration. Neurological and behavioral dysfunction was observed at 6 h and 24 h post-TBI, and this was not exacerbated by AAI. TBI induced a transient upregulation of cortical interleukin (IL)-6 and monocyte chemotactic protein (MCP)-1 mRNA expression at 6 h, which was resolved at 24 h. AAI did not modulate the inflammatory response at 6 h but prevented resolution of inflammation (IL-1, IL-6, tumor necrosis factor-α, and MCP-1 expression) at 24 h post-TBI. AAI at the time of TBI did not delay the recovery of neurological and neurobehavioral function but prevented the resolution of neuroinflammation post-TBI. PMID:24050411

To evaluate the presence of acute traumatic coagulopathy (ATC) in dogs and cats following blunt trauma and to relate coagulation variables with injury severity and admission variables. Prospective, single center, observational study from 2013 to 2014. Urban private referral hospital. Eighteen and 19 client-owned dogs and cats, respectively, sustaining blunt trauma within 8 hours of presentation without prior resuscitation; 17 healthy staff and client-owned control cats METHODS: Blood samples were collected upon presentation for measurement of blood gas, lactate, blood glucose, ionized calcium, PCV, total plasma protein, prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, platelet count, and thromboelastography. ATC was diagnosed in 1 dog and 1 cat on presentation. Hypercoagulability was documented in 4/18 (22%) of dogs and 1/19 (5.3%) of cats. In dogs, prolongation of PT (P = 0.018), aPTT (P = 0.013) and decrease in maximum amplitude (MA) (P = 0.027) were significantly associated with injury severity as measured by the animal trauma triage (ATT) score. In cats, PT, aPTT, MA, and clot strength (G) were not associated with injury severity. In cats, increasing blood glucose and lactate were significantly associated with decreasing MA (P = 0.041, P = 0.031) and G (P = 0.014, P = 0.03). In both dogs (P = 0.002) and cats (P = 0.007), fibrinogen concentration was significantly correlated with G. ATC is rare in minimally injured dogs and cats following blunt trauma. In dogs, ATT score is significantly associated with PT, aPTT, and MA, suggesting an increased risk of ATC in more severely injured animals. ATT score does not appear to predict coagulopathies in cats. Future studies including more severely injured animals are warranted to better characterize coagulation changes associated with blunt trauma. © Veterinary Emergency and Critical Care Society 2016.

Our understanding of mild traumatic brain injury (mTBI) is still in its infancy and to gain a greater understanding, relevant animal models should replicate many of the features seen in human mTBI. These include changes to diffusion tensor imaging (DTI) parameters, absence of anatomical lesions on conventional neuroimaging, and neurobehavioral deficits. The Maryland closed head TBI model causes anterior-posterior plus sagittal rotational acceleration of the brain, frequently observed with motor vehicle and sports-related TBI injuries. The injury reflects a concussive injury model without skull fracture. The goal of our study was to characterize the acute (72 h) pathophysiological changes occurring following a single mTBI using magnetic resonance imaging (MRI), behavioral assays, and histology. We assessed changes in fractional anisotropy (FA), mean (MD), longitudinal (LD), and radial (RD) diffusivities relative to pre-injury baseline measures. Significant differences were observed in both the longitudinal and radial diffusivities in the fimbria compared with baseline. A significant difference in radial diffusivity was also observed in the splenium of the corpus callosum compared with baseline. The exploratory activity of the mTBI animals was also assessed using computerized activity monitoring. A significant decrease was observed in ambulatory distance, average velocity, stereotypic counts, and vertical counts compared with baseline. Histological examination of the mTBI brain sections indicated a significant decrease in the expression of myelin basic protein in the fimbria, splenium, and internal capsule. Our findings demonstrate the vulnerability of the white matter tracts, specifically the fimbria and splenium, and the ability of DTI to identify changes to the integrity of the white matter tracts following mTBI.

Acute traumatic coagulopathy (ATC) may trigger sympathoadrenal activation associated with endothelial damage and coagulation disturbances. Overexcitation of sympathetic nerve in this state would disrupt sympathetic-vagal balance, leading to autonomic nervous system dysfunction. The aim of this study was to evaluate the autonomic function in ATC and its influence on inflammation, endothelial and coagulation activation. Male Sprague-Dawley rats were randomly assigned to sham, ATC control (ATCC) and ATC with sympathectomy by 6-hydroxydopamine (ATCS) group. Sham animals underwent the same procedure without trauma and bleeding. Following trauma and hemorrhage, rats underwent heart rate variability (HRV) test, which predicts autonomic dysfunction through the analysis of variation in individual R-R intervals. Then, rats were euthanized at baseline, and at 0, 1 and 2 h after shock and blood gas, conventional coagulation test and markers of inflammation, coagulation, fibrinolysis, endothelial damage and catecholamine were measured. HRV showed an attenuation of total power and high frequency, along with a rise of low frequency and low frequency : high frequency ratio in the ATC rats, which both were reversed by sympathectomy in the ATCS group. Additionally, sympathetic denervation significantly suppressed the increase of proinflammatory cytokines, tumor necrosis factor-α and the fibrinolysis markers including tissue-type plasminogen activator and plasmin-antiplasmin complex. Serum catecholamine, soluble thrombomodulin and syndecan-1 were also effectively inhibited by sympathectomy. These data indicated that autonomic dysfunction in ATC involves both sympathetic activation and parasympathetic inhibition. Moreover, sympathectomy yielded anti-inflammatory, antifibrinolysis and endothelial protective effects in rats with ATC. The role of autonomic neuropathy in ATC should be explored further.

Neurosurgical services are a limited resource and effective use of them would improve the health care system. Acute care surgeons (ACS) are accustomed to treating mild traumatic brain injury (TBI) including those with minor radiographic intracranial injuries. We hypothesized that ACS safely manage mild TBI with intracranial hemorrhage (ICH) on head computed tomographic (CT) scan without neurosurgical consultation (NC). We performed a retrospective analysis on all TBI patients with positive findings on head CT scan managed without NC during a 2-year period. Propensity scoring matched NC to no-NC patients on a 1:2 ratio for Glasgow Coma Scale (GCS) score, head Abbreviated Injury Scale (h-AIS) score, neurological examination, age, Injury Severity Score (ISS), findings of initial head CT scan including type and size of ICH. A total of 270 patients with mild TBI and positive CT scan findings were included (90 with NC and 180 without NC). Sixty-three percent were male, and mean (SD) age was 39 (25) years. The median GCS was 15 (13-15), and the h-AIS score was 2 (1-3). In both groups, there was no neurosurgical intervention, in-hospital mortality, or 30-day readmission. In the no-NC group, 8% of the patients had postdischarge emergency department (ED) visits compared with 4% of the NC group (p = 0.5). All patients with postdischarge ED visits in both groups were discharged home from the ED. ACS can manage mild TBI with ICH without obtaining an inpatient NC. Further guidelines should be established to help identify which patients meet criteria to be safely managed without NC. Care management/therapeutic study, level IV.
Background Mortality from trauma remains a major public health issue as it is the leading cause of death in persons aged 5 to 44 years .Uncontrolled hemorrhage and coagulopathy is responsible for over 50% of all trauma related deaths within the first 48hrs of admission. Coagulation profiles are not routinely done among trauma patients in resource limited settings and there is a paucity of data on acute traumatic coagulopathy (ATC) in sub Saharan Africa. The study was conducted to evaluate the prothrombin time and partial thromboplastin time (PT/PTT) as predictors of mortality and morbidity among major trauma patients. Methods A prospective cohort study was carried out, in which major trauma patients admitted in A&E department between December 2011 to April 2012 were recruited. Five (5) mls of venous blood was drawn from a convenient vein within 10 minutes of the patient’s arrival at A&E for analysis of PT/PTT. Patients were stratified into two groups by the presence/absence of coagulopathy then followed up for a 2 week period for morbidity and mortality. Results A total of 182 major trauma patients were recruited; 149 (81.9%) were males, the mean age was 29.5 years (SD 9.8). Prevalence of coagulopathy was 54% (98/182). The mean ISS for the ATC group was 36.9 and the non ATC group was 26.9 (p=0.001). Patients with ATC stayed longer in hospital 11.24 days than non ATC patients 8 days (p=0.001). ATC was strongly associated with ARI (p= 0.003). Mortality was more in the ATC group 29 deaths compared to 9 deaths in the non ATC group. PTT was a strong independent predictor of mortality. Conclusion A significant proportion of major trauma patients were coagulopathic. Initial coagulation profile is useful in predicting outcomes for major trauma patients. PMID:23150904

Objective: To quantitatively aggregate effects of cognitive training (CT) on cognitive and functional outcome measures in patients with traumatic brain injury (TBI) more than 12-months post-injury. Design: We systematically searched six databases for non-randomized and randomized controlled trials of CT in TBI patients at least 12-months post-injury reporting cognitive and/or functional outcomes. Main Measures: Efficacy was measured as standardized mean difference (Hedges’ g) of post-training change. We investigated heterogeneity across studies using subgroup analyses and meta-regressions. Results: Fourteen studies encompassing 575 patients were included. The effect of CT on overall cognition was small and statistically significant (g = 0.22, 95%CI 0.05 to 0.38; p = 0.01), with low heterogeneity (I2 = 11.71%) and no evidence of publication bias. A moderate effect size was found for overall functional outcomes (g = 0.32, 95%CI 0.08 to 0.57, p = 0.01) with low heterogeneity (I2 = 14.27%) and possible publication bias. Statistically significant effects were also found only for executive function (g = 0.20, 95%CI 0.02 to 0.39, p = 0.03) and verbal memory (g = 0.32, 95%CI 0.14 to 0.50, p < 0.01). Conclusion: Despite limited studies in this field, this meta-analysis indicates that CT is modestly effective in improving cognitive and functional outcomes in patients with post-acute TBI and should therefore play a more significant role in TBI rehabilitation.

Reduced integrity of white matter (WM) pathways and subtle anomalies in gray matter (GM) morphology have been hypothesized as mechanisms in mild traumatic brain injury (mTBI). However, findings on structural brain changes in early stages after mTBI are inconsistent and findings related to early symptoms severity are rare. Fifty-one patients were assessed with multimodal neuroimaging and clinical methods exclusively within 7 days following mTBI and compared to 53 controls. Whole-brain connectivity based on diffusion tensor imaging was subjected to network-based statistics, whereas cortical surface area, thickness, and volume based on T1-weighted MRI scans were investigated using surface-based morphometric analysis. Reduced connectivity strength within a subnetwork of 59 edges located predominantly in bilateral frontal lobes was significantly associated with higher levels of self-reported symptoms. In addition, cortical surface area decreases were associated with stronger complaints in five clusters located in bilateral frontal and postcentral cortices, and in the right inferior temporal region. Alterations in WM and GM were localized in similar brain regions and moderately-to-strongly related to each other. Furthermore, the reduction of cortical surface area in the frontal regions was correlated with poorer attentive-executive performance in the mTBI group. Finally, group differences were detected in both the WM and GM, especially when focusing on a subgroup of patients with greater complaints, indicating the importance of classifying mTBI patients according to severity of symptoms. This study provides evidence that mTBI affects not only the integrity of WM networks by means of axonal damage but also the morphology of the cortex during the initial post-injury period. These anomalies might be greater in the acute period than previously believed and the involvement of frontal brain regions was consistently pronounced in both findings. The dysconnected subnetwork

The objective of this study was to explore whether ketamine prevents or exacerbates acute or post-traumatic stress disorders in military trauma patients. We conducted a retrospective study of a database from the French Military Health Service, including all soldiers surviving a war injury in Afghanistan (2010-2012). The diagnosis of post-traumatic stress disorder was made by a psychiatrist and patients were analysed according to the presence or absence of this condition. Analysis included the following covariables: age; sex; acute stress disorder; blast injury; associated fatality; brain injury; traumatic amputation; Glasgow coma scale; injury severity score; administered drugs; number of surgical procedures; physical, neurosensory or aesthetic sequelae; and the development chronic pain. Covariables related to post-traumatic and acute stress disorders with a p ≤ 0.10 were included in a multivariable logistic regression model. The data from 450 soldiers were identified; 399 survived, of which 274 were analysed. Among these, 98 (36%) suffered from post-traumatic stress disorder and 89 (32%) had received ketamine. Fifty-four patients (55%) in the post-traumatic stress disorder group received ketamine vs. 35 (20%) in the no PTSD group (p < 0.001). The 89 injured soldiers who received ketamine had a median (IQR [range]) injury severity score of 5 (3-13 [1-26]) vs. 3 (2-4 [1-6] in the 185 patients who did not (p < 0.001). At multivariable analysis, only acute stress disorder and total number of surgical procedures were independently associated with the development of post-traumatic stress disorder. In this retrospective study, ketamine administration was not a risk factor for the development of post-traumatic stress disorder in the military trauma setting. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

Acute leukemia is a fatal disease in adults that not only affects the patients who suffer from it but also their family caregivers. No studies have investigated post-traumatic stress disorder symptoms (PTSS) in family caregivers of adult patients with acute leukemia using a matched sample. The current study examined PTSS in adult patients with acute leukemia and their family caregivers and investigated the factors associated with caregivers' PTSS. A total of 163 patient-caregiver dyads completed questionnaires assessing their PTSS, psychological resilience, and perceived social support. Hierarchical linear regression was used to explore the related factors of caregivers' PTSS. More caregivers than patients met caseness criteria for PTSS (36.8% vs. 18.4%, p < 0.001). Among caregivers, being more closely related to the patients (e.g., spouses and parents), having patients with higher PTSS and having lower psychological resilience were independently associated with more severe PTSS. Caregivers of acute leukemia patients had significantly more severe PTSS than did their patients. This study is the first to investigate PTSS among family caregivers of adult patients with acute leukemia and its related factors in a matched sample. More attention should be paid to the caregivers of patients with acute leukemia to minimize their PTSS and thus improve mental health of caregivers and reduce potential negative consequences for the patients themselves.

To determine which postoperative rehabilitation regime is superior following surgical repair of acute Achilles tendon rupture. The primary outcomes were patient safety and satisfaction. Intervention meta-analysis. The MEDLINE and CINAHL electronic databases were searched from their date of inception until June 2015 using keywords related to acute Achilles tendon rupture, surgical repair and rehabilitation. The electronic database search was supplemented with forward citation tracking using the Web of Science. Randomised controlled trials comparing clinical and/or patient-reported outcomes between patients receiving early functional postoperative ankle motion and weight bearing (bracing group), and traditional ankle immobilisation with a non-weight bearing rigid cast (cast group) were eligible for inclusion. Fourteen articles were identified as potentially eligible; 10 sufficient-quality randomised controlled trials involving 570 patients were included for meta-analysis. A high proportion of patients were able to return to prior employment and sporting activity in both groups. Five of the six trials measuring the time interval showed a faster return to prior sporting level in the bracing group. Subjective patient outcomes were significantly better in the bracing group (for good and excellent results, p=0.01; OR, 3.13; 95% CI 1.30 to 7.53). There was no difference in major complications between the two groups (p=0.21; RD, -0.03; 95% CI -0.06 to 0.01). Dynamometry and anthropometry measurements favoured functional rehabilitation at 6-12 weeks postoperation; however, by 6 months postoperative, the differences were negligible. Compared to traditional ankle immobilisation, with a non-weight bearing cast following surgical repair of acute Achilles tendon rupture, early dynamic functional rehabilitation is as safe with higher patient satisfaction.

The best treatment of acute Achilles tendon rupture has been discussed for decades. During the past half decade, evidence has increased in favor of nonoperative treatment and dynamic and weightbearing rehabilitation. We hypothesized that the treatment strategies would show great variation and that adherence to evidence-based recommendations would not be as good as desired. The purpose of the present study was to investigate how acute Achilles tendon rupture is treated in Scandinavia. A questionnaire was distributed to all orthopedic departments treating acute Achilles tendon ruptures in Denmark, Sweden, Norway, and Finland. The questionnaire was returned by 138 of 148 departments (response rate 93%). Two-way tables with Fisher's exact test were used for statistical analysis. In Denmark, Norway, Sweden, and Finland, 19 of 23 (83%), 44 of 48 (92%), 26 of 40 (65%), and 8 of 27 (30%) departments recommended surgical treatment (p < .001). Dynamic rehabilitation was used significantly less often in Denmark (5 of 23 [22%]), Norway (17 of 45 [38%]), and Sweden (11 of 40 [28%]) than in Finland (15 of 26 [58%]; p = .015). A significant difference was found among the countries in the educational level of the performing surgeons (p < .001). Surgical treatment was the treatment of choice in Danish, Norwegian, and Swedish hospitals regardless of the increasing evidence favoring nonoperative treatment. Although increasing evidence has favored dynamic rehabilitation, it has gained limited use across Scandinavia. Weightbearing was used in most hospitals. Surgery was performed by junior surgeons in most hospitals across Scandinavia. Treatment algorithms showed considerable variation and often did not adhere to the clinical evidence.

There is discordance in the results from meta-analyses on surgical versus non-surgical treatment for acute Achilles tendon rupture. We systematically reviewed the overlapping meta-analyses on this topic to provide information that will be helpful to decision makers when selecting treatments based on the current best available evidence. We comprehensively searched multiple databases for systematic reviews that compared surgical and non-surgical treatments for acute Achilles tendon rupture. We only included meta-analyses that comprised randomized controlled trials (RCTs). The methodological quality and extracted data were assessed. The meta-analysis that offered the best evidence was ascertained with the Jadad decision algorithm. Nine meta-analyses were included in our study and all of them included RCTs with Level-II evidence. Assessment of Multiple Systematic Reviews (AMSTAR) scores ranged from 5 to 10 (median 7). The Jadad decision algorithm was used to select a high-quality meta-analysis with more RCTs. The results from this study showed that when functional rehabilitation was used, non-surgical intervention was similar to surgical treatment regarding the incidence of range of motion, rerupture, calf circumference and functional outcomes, and the incidence of other complications was reduced. Non-surgical intervention significantly increased the rerupture rate if functional rehabilitation was not considered. The findings of meta-analyses regarding surgical versus non-surgical treatment for acute Achilles tendon rupture are inconsistent. According to this systematic review of overlapping meta-analyses, the current best available evidence suggests that centers offering functional rehabilitation may prefer non-surgical intervention. Surgical treatment may be preferred at centers that do not have functional rehabilitation. Copyright © 2016 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

Introduction Several studies have shown that lactoferrin (LF) and neopterin (NT) are correlated with infection. The aim of this study is to determine whether serum levels of LF and NT are associated with postoperative infectious complications in patients with acute traumatic spinal cord injury. Material and methods A total of 268 patients with acute traumatic spinal cord injury who underwent spinal surgery were enrolled in this study. Serum levels of LF, NT, and C-reactive protein (CRP), in addition to white blood cell count (WBC) and erythrocyte sedimentation rate (ESR), were measured preoperatively and 24 h postoperatively. Results In total, 22 of 268 patients (8.2%) developed postoperative infectious complications. The levels of serum LF, NT, and CRP were significantly higher in the infected patients than in the non-infected patients. No significant differences were observed in postoperative WBC count and ESR between the two groups. Multivariate logistic regression revealed that LF (OR: 1.004 (1.002–1.007)), NT (OR: 1.137 (1.054–1.227)), and CRP (OR: 1.023 (1.002–1.044)) were significantly associated with the presence of postoperative infectious complications. The area under receiver operating characteristic curves for LF, NT, and CRP was 0.709, 0.779, and 0.629, respectively. Conclusions Elevated serum concentrations of LF and NT are associated with early infection after surgery. Compared to CRP, elevated levels of LF and NT are better indicators for predicting postoperative infectious complications in patients with acute traumatic spinal cord injury. PMID:24273571

Ventricular septal rupture (VSR) is an uncommon but well-recognized mechanical complication of acute myocardial infarction (AMI). The outcome of VSR remains poor even in the era of reperfusion therapy. We reviewed our experience with surgical repair of post-infarction VSR and analyzed outcomes in an attempt to identify prognostic factors. From October 1995 to December 2013, data from 47 consecutive patients (mean age, 68 ± 9.5 years) with post-infarction VSR who underwent surgical repair at our institute were retrospectively reviewed. The preoperative conditions, morbidity and surgical mortality were analyzed. Multivariate analysis was subsequently carried out by constructing a logistic regression model in order to identify independent predictors of postoperative mortality. Long term survival function were estimated using the Kaplan-Meier method and compared using the log-rank test. Percutaneous coronary intervention was performed in 17 (36.2%) patients, intra-aortic balloon pump (IABP) was used in 34 (72.3%), and six (12.8%) were supported with extracorporeal membrane oxygenation (ECMO) preoperatively. Forty-one (87.2%) patients received emergent surgical treatment. Concomitant coronary artery bypass grafting was performed in 27 (57.4%) patients. Operative mortality was 36.2% (17 of 47). The survival rate was 59.3% with concomitant CABG and 70% without concomitant CABG (p = 14). Multivariate analysis revealed that the survivors had higher preoperative left ventricular ejection fractions (LVEFs) compared with those who died (51 ± 13.7% vs. 36.6 ± 6.4% , respectively; p < 0.001) and lower European system for cardiac operative risk evaluation II (EuroSCORE II) (22.9 ± 14.9 vs. 38.3 ± 13.9, respectively; p < 0.001). The patients receiving total revascularization has long term survival benefit (p = 0.028). Post-infarction VSR remains a serious and challenging complication of AMI in the modern surgical era. The EuroSCORE II can

The causes of heel cord pain after repair of acute rupture of the Achilles tendon are unclear. The proposed etiologies include nonabsorbable suture granuloma formation, alteration of the pain receptors threshold in the tendon, and distension of the paratenon by the hypertrophied tendon, underlying tendinopathy, postrepair neovascularization, and peritendinous fibrous adhesion. We present an endoscopic technique of adhesiolysis of the Achilles tendon to deal with the various possible causes of postrepair heel cord pain.

We aimed to systematically review the efficacy of mannitol (MTL) on patients with acute severe traumatic brain injury (TBI). Databases such as PubMed (US National Library of Medicine), CENTRAL (The Cochrane Library 2014, Issue 3), ISI (Web of Science: Science Citation Index Expanded), Chinese Biomedicine Database (CBM), and China Knowledge Resource Integrated Database (CNKI) have been searched for relevant studies published between 1 January 2003 and 1 October 2014. We have established inclusion and exclusion criteria to identify RCTs, which were suitable to be enrolled in the systematic review. The comparison group could be hypertonic saline (HS), hydroxyethyl starch, or others. The quality assessment was based on the Cochrane Handbook for Systematic Reviews of Interventions Version 5.0.1 and modified Jadad score scale. The major outcome was mortality, followed by the secondary outcomes such as neurological outcome, days on intensive care unit (ICU), and ventilator day. In addition, intracranial pressure (ICP), cerebral perfusion pressure (CPP), and mean arterial pressure (MAP) were used as the surrogate endpoints. Data synthesis and meta-analysis was conducted by using R (version 3.7-0.). When 176 potential relevant literatures and abstracts have been screened, four RCTs met all the inclusion criteria and were enrolled for the meta-analysis. Amongst all the enrolled studies, two trials have provided the primary outcome data. There was no heterogeneity between two studies (I (2) = 0 %) and a fixed model was used for meta-analysis (n = 53), pooled result indicated that the mortality was similar in mannitol intervention and control treatment, OR = 0.80, 95 % CI [0.27, 2.37], P = 0.38. We found that both mannitol and HS were efficient in decreasing the ICP. Furthermore, the effect of the HS on the ICP appeared to be more effective in the patients with diffuse brain injuries than mannitol did. As a conclusion, the mannitol therapy cannot reduce the

We report a case of an iatrogenic tracheal rupture following an endotracheal intubation. The 78-year-old patient was admitted to the intensive care unit because of an acute respiratory failure related to a severe nosocomial pneumonia occurring 21 days after an abdominal aorta surgery. His main antecedent was a cigarette smoke-induced chronic obstructive pulmonary disease. Immediately after being intubated, a traumatic tracheobronchial rupture was suspected because of the sudden appearance of cervicothoracic subcutaneous emphysema. A thoracic computed tomography with multiplanar reformations confirmed the diagnosis and the evolution was unfortunately rapidly unfavourable. Risk factors, clinical and radiological aspects, and management of this rare but serious complication of endotracheal intubation will be discussed.

Summary Background: At present, it is unclear which is the best management for Achilles tendon rupture. Purpose: We assess the clinical, functional and imaging outcomes of active patients undergoing 3 different types of management for acute subcutaneous rupture of the Achilles tendon, including conservative cast immobilization, traditional open surgery and percutaneous repair. Methods: 26 active patients were managed for a rupture of the Achilles Tendon from January 2007 to March 2008. Anthropometric measurements, Functional assessment, Isometric strength, Ultrasonographic assessment, Patient satisfaction, Working life, Physical activity, Functional score and Complications were recorded retrospectively. Results: All 23 (21 men, 2 women) patients were reviewed at a minimum follow-up of 24 months (average 25.7, range 24 to 32 months, SD: 6.3) from the index injury. Thermann scores and patient satisfaction were significantly higher following surgery than conservative management with no significance between open and minimally invasive operated patients. Sensitive disturbances occur in up to 12% of open repairs and 1.8% of patients managed nonsurgically. Conclusions: Clinical and functional outcomes following surgical repair, percutaneous and open, of the Achilles tendon are significantly improved than following conservative management. Level of evidence: Level III. PMID:28717611

Left ventricular free wall rupture (LVFWR) may complicate an acute myocardial infarction (AMI); its frequency ranges from 1 to 6 percent. In the era of coronary care units, LVFWR is the second cause of in-hospital death, after pump failure. The subacute presentation accounts for 2-3 percent of total hospital admissions for AMI. Heart rupture may not be suddenly fatal and sometimes there is enough time for surgical repair. Electromechanical dissociation is neither the only nor the main clinical presentation. More subtle symptoms occurring hours or days before the final event include unexplained hypotension and transient bradycardia and some ECG features such as persistent ST-segment elevation with T-waves failing to invert in the same leads. On echocardiographic subcostal view, pericardial effusion of more than 5-10 mm, with echo-dense masses overlying the heart independently of cardiac tamponade, is highly suggestive of heart rupture. If pericardiocentesis yields hemorrhagic fluid, surgical intervention is mandatory, providing both diagnostic confirmation and definitive treatment. Medical management strategies (prolonged bed rest, beta-blockade therapy) are still experimental but could become suitable for particular subsets of patients (elderly patients and patients at a high surgical risk). We report two cases of subacute LVFWR and review the currently available literature.

Acute traumatic coagulopathy is associated with adverse outcomes including death. Previous studies examining acute traumatic coagulopathy's relation with mortality are limited by inconsistent criteria for syndrome diagnosis, inadequate control of confounding, and single-center designs. In this study, we validated the admission international normalized ratio as an independent risk factor for death and other adverse outcomes after trauma and compared two common international normalized ratio-based definitions for acute traumatic coagulopathy. Multicenter prospective observational study. Nine level I trauma centers in the United States. A total of 1,031 blunt trauma patients with hemorrhagic shock. None. International normalized ratio exhibited a positive adjusted association with all-cause in-hospital mortality, hemorrhagic shock-associated in-hospital mortality, venous thromboembolism, and multiple organ failure. Acute traumatic coagulopathy affected 50% of subjects if defined as an international normalized ratio greater than 1.2 and 21% of subjects if defined by international normalized ratio greater than 1.5. After adjustment for potential confounders, acute traumatic coagulopathy defined as an international normalized ratio greater than 1.5 was significantly associated with all-cause death (odds ratio [OR], 1.88; p < 0.001), hemorrhagic shock-associated death (OR, 2.44; p = 0.001), venous thromboembolism (OR, 1.73; p < 0.001), and multiple organ failure (OR, 1.38; p = 0.02). Acute traumatic coagulopathy defined as an international normalized ratio greater than 1.2 was not associated with an increased risk for the studied outcomes. Elevated international normalized ratio on hospital admission is a risk factor for mortality and morbidity after severe trauma. Our results confirm this association in a prospectively assembled multicenter cohort of severely injured patients.

The swirl sign is identified as a small area of low attenuation within an intracranial hyperattenuating clot on non-enhanced computed tomography (CT) scans of the brain, which represents active bleeding. The purpose of this study was to evaluate the incidence of the swirl sign among patients with acute epidural hematoma (AEDH) and to identify its prognostic value and impact on surgical treatment. A retrospective review was performed of patients with a diagnosis of traumatic EDH by CT scan who were surgically treated at the Department of Neurosurgery of the First People's Hospital of Jingmen between January 2010 and January 2014. Patients with combined or open craniocerebral injuries and those who did not undergo surgical treatment were excluded. Of the 147 patients evaluated, 21 (14%) exhibited the swirl sign on non-enhanced CT scans of the brain. Univariate analysis revealed a significant correlation between the occurrence of the swirl sign and preoperative Glasgow coma scale scores, preoperative mydriasis, time from injury to CT scan, and intraoperative hematoma volume. Compared with patients without this sign, those exhibiting the swirl sign had a higher mortality rate (24 vs. 6%, respectively; P = 0.028) and a worse outcome (Glasgow Outcome Scale score ≤ 3: 38 vs. 15%, respectively; P = 0.027) at 3 months. An adjusted analysis showed that the occurrence of the swirl sign was an independent predictor of poor outcome (death: odds ratio (OR) = 4.61; 95% confidence interval (CI): 1.34-15.82; P < 0.05; 3-month Glasgow Outcome Scale score ≤ 3: OR = 3.47; 95% CI: 1.27-9.49; P < 0.05). In conclusion, the occurrence of the swirl sign on the head CT scan of patients with AEDH was found to be significantly associated with poor outcome. Therefore, early identification of this sign and aggressive management with early surgical evacuation is crucial for improving patient outcome.

This review examines the best available evidence on the aetiology of childhood acute non-traumatic coma in resource-poor countries (RPCs), discusses the challenges associated with management, and explores strategies to address them. Publications in English and French which reported on studies on the aetiology of childhood non-traumatic coma in RPCs are reviewed. Primarily, the MEDLINE database was searched using the keywords coma, unconsciousness, causality, aetiology, child, malaria cerebral, meningitis, encephalitis, Africa, Asia, and developing countries. 14 records were identified for inclusion in the review. Cerebral malaria (CM) was the commonest cause of childhood coma in most of the studies conducted in Africa. Acute bacterial meningitis (ABM) was the second most common known cause of coma in seven of the African studies. Of the studies in Asia, encephalitides were the commonest cause of coma in two studies in India, and ABM was the commonest cause of coma in Pakistan. Streptococcus pneumoniae was the most commonly isolated organism in ABM. Japanese encephalitis, dengue fever and enteroviruses were the viral agents most commonly isolated. Accurate diagnosis of the aetiology of childhood coma in RPCs is complicated by overlap in clinical presentation, limited diagnostic resources, disease endemicity and co-morbidity. For improved outcomes, studies are needed to further elucidate the aetiology of childhood coma in RPCs, explore simple and practical diagnostic tools, and investigate the most appropriate specific and supportive interventions to manage and prevent infectious encephalopathies.

Several meta-analyses comparing early functional rehabilitation and traditional immobilization following surgical Achilles tendon repair after acute rupture have been published. However, they have led to conflicting conclusions. The aims of this systematic review were to select high-quality meta-analyses from multiple discordant meta-analyses and to provide a postoperative rehabilitation strategy following surgical repair using currently available evidence. We performed a comprehensive search using the PubMed and Embase databases and the Cochrane Library. Assessment of Multiple Systematic Reviews (AMSTAR) instrument was used to assess the methodological quality. Three investigators independently applied the Jadad decision algorithm. Their results were then compared to ensure selection of a meta-analysis that provided the highest quality of evidence. Six meta-analyses met the eligibility criteria. AMSTAR scores ranged from 6 to 10. According to the Jadad decision algorithm, a high-quality meta-analysis with a greater number of RCTs was selected. This meta-analysis showed that early functional rehabilitation was superior to cast immobilization in terms of patient satisfaction and the time to return to pre-morbid sporting levels. There were no differences regarding major complications or the time before return to prior employment and sporting activity. Thus, we recommend early functional rehabilitation as the postoperative strategy for acute Achilles tendon ruptures. PMID:28054658

Assessment of acute mild traumatic brain injury (mTBI) symptoms after a combat blast could aid diagnosis and guide follow-up care. Our objective was to document acute mTBI symptoms following a combat blast and to examine associations between acute symptoms and mental health and service discharge outcomes. A retrospective cohort study was conducted with 1656 service personnel who experienced a combat blast-related mTBI in Iraq. Acute mTBI symptoms were ascertained from point-of-injury medical records. The associations between acute symptoms and posttraumatic stress disorder (PTSD), postconcussion syndrome (PCS), and type of service discharge were examined. Disability discharge occurred in 11% of patients, while 36% had a non-disability discharge and 52% had no recorded discharge. A PTSD and PCS diagnosis was made in 19% and 15% of the sample, respectively. The most common acute mTBI symptoms were headache (62.8%), loss of consciousness (LOC) (34.5%), and tinnitus (33.2%). LOC was predictive of PTSD (odds ratio [OR] 1.54; 95% confidence interval [CI] 1.18, 2.00) and PCS (OR 2.08; 95% CI 1.56, 2.77), while altered mental status (OR 1.53; 95% CI 1.07, 2.17) and previous blast history (OR 1.83; 95% CI 1.15, 2.90) also were predictive of PCS. While no acute mTBI symptoms were associated with discharge outcomes, injury severity was associated with disability discharge. LOC after blast-related mTBI was associated with PTSD and PCS, and injury severity was predictive of disability discharge. The assessment of cognitive status immediately after a blast could assist in diagnosing mTBI and indicate a need for follow-up care.

Acute vascular abdomen is a severe and life-threatening pathology due to arterial degeneration, leading to hemorrhage or arterial occlusion leading to ischemia. Differential diagnosis of patients with severe abdominal pain and/or shock include several vascular and traumatic diseases, the most common being rupture of abdominal aortic aneurysm (AAA), or less frequently rupture of visceral artery aneurysm. Also acute aortic dissection, iatrogenic injury and acute mesenteric ischemia may lead to acute vascular abdomen. Clinical evaluation of the haemodynamic status of the patient may be very difficult, and may require airway maintenance and ventilation with a rapid treatment of hemorrhagic shock. In the stable patient with an uncertain diagnosis, CT scan, NMR and selective angiography may be helpful in diagnosis before vascular repair. On the contrary, the unstable patient, after hemodynamic resuscitation, must be operated on expeditiously. We present our vascular algorithms, to assess timing of diagnosis and treatment of this severe acute disease.
In his recent publication (2004), in which he favors the psycho-dynamic approach, M. Bertrand underlines the importance of traumatic matter at the heart of new clinical, methodological and epistemological challenges of psychopathology. Our contribution ("post-traumatic psychosis") comes within that prospect in reference to the semiology of traumas generated by extreme situations, such as the tsunami in South Asia (December 2004), the terrorist attacks in Madrid (March 2004) or the hostage taking in North Ossetia (September 2004). Four principle sets of themes lead us to suggest a traumatic psychosis when the person shows symptoms of a neurotic psychic structure: 1. There's no traumatic representation or psychic inscription of the event. Sideration (and its stupor-like confusion symptoms) or panic flight (together with hallucinations or acute delirious fits) often illustrate this first clinical aspect. 2. According to the psychodynamic frame of reference, psychic processes tend to ignore the pleasure/displeasure principle. They are governed by the "invasion" of affects of pain and compulsion to repeat. 3. The models of neurosis and psychic conflict are not efficient in the management of the "quota of affect" and the drive influence. 4. It would be necessary to add, from a psychopathological point of view, the appearance of temporary fits of mental confusion, self-destructive and autolysis behavior. The frame of reference of a DSM IV type "descriptive" psychopathology (ie acute Stress Disorder) seems to de inadequate to convey the implemented post traumatic stakes. If trying to soothe the symptoms is undeniably important, psychic disorganizations that generate a semiology that is essentially present in the symptomatology of the psychoses cannot be ignored. A first clinical approach makes it possible to specify the argumentation of our proposal: "a post-traumatic psychosis". It is supported by five main syndromic classes: 1) the symptoms are often more or less

Objectives: While a growing number of studies provide evidence of neural and cognitive decline in traumatic brain injury (TBI) survivors during the post-acute stages of injury, there is limited research as of yet on environmental factors that may influence this decline. The purposes of this paper, therefore, are to (1) examine evidence that environmental enrichment (EE) can influence long-term outcome following TBI, and (2) examine the nature of post-acute environments, whether they vary in degree of EE, and what impact these variations have on outcomes. Methods: We conducted a scoping review to identify studies on EE in animals and humans, and post-discharge experiences that relate to barriers to recovery. Results: One hundred and twenty-three articles that met inclusion criteria demonstrated the benefits of EE on brain and behavior in healthy and brain-injured animals and humans. Nineteen papers on post-discharge experiences revealed that variables such as insurance coverage, financial, and social support, home therapy, and transition from hospital to home, can have an impact on clinical outcomes. Conclusion: There is evidence to suggest that lack of EE, whether from lack of resources or limited ability to engage in such environments, may play a role in post-acute cognitive and neural decline. Maximizing EE in the post-acute stages of TBI may improve long-term outcomes for the individual, their family and society. PMID:23616755

A 41-year-old man suffered severe polytrauma and developed a traumatic myocardial infarction with cardiogenic shock. Thrombolysis as well as coronary bypass grafting was contraindicated due to accompanying injuries. An attempted early coronary revascularization by percutaneous transluminal coronary angioplasty (PTCA) failed due to dissection of the left interventricular coronary artery. Treatment of cardiac insufficiency was complicated by intraabdominal haemorrhage enforcing emergency laparotomy. Intraaortic balloon counterpulsation proved to be efficient in supporting circulation in these circumstances. The case report documents the practicability and importance of treating both myocardial ischaemia and attending injuries in an equivalent and coordinated manner in traumatic myocardial infarction.

[Purpose] The aim of study was to evaluate the impact of physical therapy on the recovery of motor and mental status in patients who sustained a severe traumatic brain injury, according to coma duration in acute and post-acute rehabilitation. [Subjects and Methods] The study population comprised patients with levels of consciousness ranging from 3 to 8 according to Glasgow Coma Scale score. The patients were divided into 2 groups based on coma duration as follows: group 1, those who were in a coma up to 1 week, and group 2, those who were in a coma for more than 2 weeks. The recovery of the patients’ motor function was evaluated according to the Motor Assessment Scale and the recovery of mental status according to the Mini-Mental State Examination. [Results] The evaluation of motor and mental status recovery revealed that the patients who were in a coma up to 1 week recovered significantly better after physical therapy during the acute rehabilitation than those who were in a coma for longer than 2 weeks. [Conclusion] The recovery of motor and mental status of the patients in acute rehabilitation was significantly better for those in a coma for a shorter period. PMID:27512262

Functional disconnectivity during the resting state has been observed in mild traumatic brain injury (mTBI) patients during the acute stage. However, it remains largely unknown whether the abnormalities are related to specific frequency bands of the low-frequency oscillations (LFO). Here, we used the amplitude of low-frequency fluctuations (ALFF) to examine the amplitudes of LFO in different frequency bands (slow-5: 0.01-0.027 Hz; slow-4: 0.027-0.073 Hz; and typical: 0.01-0.08 Hz) in patients with acute mTBI. A total of 24 acute mTBI patients and 24 age-, sex-, and education-matched healthy controls participated in this study. In the typical band, acute mTBI patients showed lower standardized ALFF in the right middle frontal gyrus and higher standardized ALFF in the right lingual/fusiform gyrus and left middle occipital gyrus. Further analyses showed that the difference between groups was concentrated in a narrower (slow-4) frequency band. In the slow-5 band, mTBI patients only exhibited higher standardized ALFF in the occipital areas. No significant correlation between the mini-mental state examination score and the standardized ALFF value was found in any brain region in the three frequency bands. Finally, no significant interaction between frequency bands and groups was found in any brain region. We concluded that the abnormality of spontaneous brain activity in acute mTBI patients existed in the frontal lobe as well as in distributed brain regions associated with integrative, sensory, and emotional roles, and the abnormal spontaneous neuronal activity in different brain regions could be better detected by the slow-4 band. These findings might contribute to a better understanding of local neural psychopathology of acute mTBI. Future studies should take the frequency bands into account when measuring intrinsic brain activity of mTBI patients.

Post-traumatic fatigue (PTF) is a common, disabling, and often chronic symptom following traumatic brain injury (TBI). Yet, the impact of chronic cognitive and physical fatigue and their associations with psychiatric, sleep, cognitive, and psychosocial sequelae in mild-moderate TBI remain poorly understood. Sixty Veterans with a history of mild-moderate TBI and 40 Veteran controls (VC) were administered the Modified Fatigue Impact Scale, a validated measure of TBI-related cognitive and physical fatigue as well as measures of neuropsychiatric, psychosocial, sleep, and objective cognitive functioning. Compared to VC, TBI Veterans endorsed significantly greater levels of cognitive and physical fatigue. In TBI, psychiatric symptoms, sleep disturbance, and post-traumatic amnesia (PTA) were associated with both cognitive and physical fatigue, while loss of consciousness (LOC) and poor attention/processing speed were related to elevations in cognitive fatigue only. In regression analyses, anxiety, sleep disturbance, and LOC significantly predicted cognitive fatigue, while only post-traumatic stress symptoms and PTA contributed to physical fatigue. Cognitive and physical fatigue are problematic symptoms following mild-moderate TBI that are differentially associated with specific injury and psychiatric sequelae. Findings provide potential symptom targets for interventions aimed at ameliorating fatigue, and further underscore the importance of assessing and treating fatigue as a multi-dimensional symptom following TBI.

Excellent results are reported from both nonoperative and operative treatment of Achilles tendon rupture. To describe a new nonoperative treatment protocol for Achilles tendon ruptures and compare outcomes with operative treatment. Retrospective cohort study. We treated 23 patients nonoperatively with an equinus ankle cast and boot and compared their outcome with that of a group of 24 patients previously treated operatively. Muscle strengthening and walking with full weightbearing were started as soon as tolerated in both groups. Follow-up examinations were performed for 18 nonoperatively treated patients after 23 months and for 15 operatively treated patients after 49 months. Subsidence of pain, return to unaided walking, and return to work was faster in the nonoperatively treated group. Patient satisfaction, return to sports, and ultimate strength was the same for both groups. The complication rate was similar, except for reruptures: four early in the nonoperative group and one late in the operative group. Two types of reruptures occurred in the nonoperative group: 1). normally healing tendon subjected to new trauma, rerupturing in the healing zone, and achieving a good result with continued nonoperative treatment; and 2). tendon failing proximal to the initial rupture at the muscle-tendon junction, without trauma, requiring operative repair and augmentation. Results of operative and nonoperative treatment were equivalent.

Between September 1987 and November 1989, we treated 90 consecutive patients with an acute anterior cruciate ligament (ACL) rupture with the multiple suture technique and iliotibial band augmentation. Seventy of these patients were re-examined 2 to 5 years after the operation (mean 3.5 years), the examination consisting of a questionnaire, clinical examination, laxity tests with the KSS machine (Acufex), radiological examination and isokinetic muscle strength testing (Cybex 6000). There were 32 men and 38 women (mean age 34 years). The injury was sustained in sports in 44 (63%) cases, and the sports most frequently involved were downhill skiing (18 cases), soccer (9 cases) and volleyball (5 cases). Of the injuries, 38 were isolated ACL ruptures and 31, ACL ruptures combined with a medial CL rupture. In 9 cases, an additional meniscus injury and in one case an additional posterior CL - lateral CL rupture was found. At the follow-up, 55 patients (79%) were satisfied with the end result, and according to our objective functional criteria 55 (79%) had an excellent or good outcome. According to the Lysholm score, 53 (76%) patients were excellent or good (> or = 82 points). In the Lachman test, 29 knees (41%) were completely stable. The Lachman test was mildy positive in 40 knees (57%) (36 had 1+ laxity and 4, 2+ laxity), and one patient had 3+ laxity with a hard end-point. Similarly, the anterior drawer test was negative in 53 knees (76%), and the other 17 (24%) had mild laxity (16 had 1+ laxity and 1, 2+ laxity). The total anterior-posterior laxity measured with the KSS averaged 9.7 +/- 3.5 mm in the injured knee and 7.3 + 3.0 mm in the uninjured knee (the laxity measured at a knee angle of 20 degrees of flexion). Corresponding values at a knee angle of 90 degrees of flexion were 6.1 +/- 2.4 mm and 4.7 +/- 1.9 mm, respectively. The pivot shift test was negative in 62 patients (89%) and 1+ positive in the remaining 8 patients (11%). Fifty-eight patients (83%) had full

The aim of this study was to evaluate the effectiveness of platelet-rich plasma (PRP) in the nonoperative treatment of acute Achilles tendon rupture. This was a comparative study that included a prospective cohort and a historical control group. The control group was formed from a randomized trial in which one arm of the trial underwent nonoperative treatment, including accelerated functional rehabilitation after acute Achilles tendon rupture identical to that performed in the prospective treatment group. Patients in the prospective group were recruited consecutively and were administered 2 injections of PRP during the first 2 weeks after the injury. The primary outcome was isokinetic plantar flexion strength at 1 and 2 years after injury. Secondary outcomes included range of motion (ROM), calf circumference, and Leppilahti score. The ankle-hindfoot scale (American Orthopedic Functional Ankle Scale [AOFAS]) was administered to patients who received the PRP injection in the prospective group but was not measured for the historical group. A total of 73 patients participated in the prospective PRP study group and were compared with a retrospective control group of 72 patients from a previous randomized controlled trial (RCT). The mean difference between groups in isokinetic plantar flexion strength (injured/uninjured) at 1 year after injury was -4.3% (95% confidence interval [CI], -15.9 to 7.3; P = .5) and 2.4% (95% CI, -8.6 to 13.5; P = .7) at 30°/s and 60°/s, respectively. Results at 2 years after injury were -3.1% (95% CI, -13.5 to 7.2; P = .6) and 4.8% (95% CI, -3.5 to 13.1; P = .3) at 30°/s and 60°/s, respectively. All secondary outcomes were also not statistically different. The results of this study suggest that there is no measurable clinical benefit to the addition of PRP to the treatment regimen for nonoperatively treated acute Achilles tendon rupture.

Abdominal aortic aneurysm rupture is associated with a systemic inflammatory response syndrome and acute lung injury. Using a selective inducible nitric oxide synthase (iNOS) inhibitor, N(6)-(iminoethyl)-lysine (L-NIL), we explored the role of iNOS in the early pro-inflammatory signaling and acute lung injury in experimental abdominal aortic aneurysm rupture. Anesthetized rats were randomized to sham control or shock and clamp (s + c) groups, which underwent one hour of hemorrhagic shock, followed by 45 minutes of supramesenteric aortic clamping, and then two hours resuscitated reperfusion. Animals in s + c were randomized to receive intravenous L-NIL at 50 microg/kg/h or saline at the start of reperfusion. Pulmonary permeability to (125)I-labeled albumin, myeloperoxidase (MPO) activity, cytokine levels, and semi-quantitative RT-PCR for mRNA were indicators of microvascular permeability, leuco-sequestration, and pro-inflammatory signaling, respectively. Lung permeability index were significantly increased in s + c compared to sham (4.43 +/- 0.96 versus 1.30 +/- 0.17, P < 0.01), and attenuated by L-NIL treatment (2.14 +/- 0.70, P < 0.05). Lung tissue MPO activity was significantly increased in s + c compared to sham (2.80 +/- 0.32 versus 1.03 +/- 0.29, P < 0.002), and attenuated by L-NIL treatment (1.50 +/- 0.20, P < 0.007). Lung tissue iNOS activity was significantly increased in s + c compared to sham animals (P < 0.05), and attenuated by L-NIL treatment (P < 0.05). Lung tissue iNOS mRNA was upregulated 8-fold in s + c compared to sham (P < 0.05). Data represents mean +/- standard error mean, comparisons with ANOVA. These data suggest that in our model of ruptured abdominal aortic aneurysm iNOS plays a crucial role in reperfusion lung injury. Selective inhibition of iNOS during early reperfusion prevents neutrophil mediated acute lung injury.

Achilles tendon rupture is a common injury of the foot and ankle. However, the optimal treatment strategy for Achilles tendon rupture is still not established. This study was conducted to compare the efficacy and complications of mini-incision repair with double-Tsuge loop sutures and open repair with modified Kessler sutures. We evaluated data from 60 patients with acute closed Achilles tendon ruptures who underwent mini-incision repair with double-Tsuge loop sutures (n = 30) or open repair with modified Kessler sutures (n = 30) from 2006 to 2010 in an ongoing prospective study conducted by us and have finished at least 18-month follow-up or finished the study. The AOFAS Ankle-Hindfoot score, ATRS, maximal ankle range of motion and the time to achieve 20 continuous single heel raises after operation were recorded to compare the efficacy. The complications were also evaluated. During a mean follow-up of 25 months after surgery, the time to achieve 20 continuous single heel raises after operation of patients in Group Mini was significantly shorter than patients in Group Open. Moreover, the mini-incision with double-Tsuge repair was associated with a significantly shorter operating time, smaller incision length, and lower rate of complications. The mini-incision with double-Tsuge suture method in our study was shown to provide earlier strength recovery, as well as shorter operation time, less complications and improved cosmetic appearance.

Several recent global traumatic brain injury (TBI) initiatives rely on practice variation in diagnostic and treatment methods to answer effectiveness questions. One of these scientific dilemmas, the surgical management of the traumatic acute subdural hematoma (ASDH) might be variable among countries, among centers within countries, and even among neurosurgeons within a center, and hence be amenable for a comparative effectiveness study. The aim of our questionnaire, therefore, was to explore variations in treatment for ASDH among neurosurgeons in similar centers in a densely populated geographical area. An online questionnaire, involving treatment decisions on six case vignettes of ASDH, was sent to 93 neurosurgeons in The Netherlands and Belgium. Clinical and radiological variables differed per case. Sixty neurosurgeons filled out the questionnaire (response rate 65%). For case vignettes with severe TBI and an ASDH, there was a modest variation in the decision to evacuate the hematoma and a large variation in the decision to combine the evacuation with a decompressive craniectomy. The main reasons for operating were "neurological condition" and "mass effect." For ASDH and mild/moderate TBI, there was large variation in the decision of whether to operate or not, whereas "hematoma size" was the predominant motivation for surgery. Significant inter-center variation for the decision to evacuate the hematoma was observed (p = 0.01). Most pronounced was that 1 out of 7 (14%) neurosurgeons in one region chose a surgical strategy compared with 9 out of 10 (90%) in another region for the same scenario. In conclusion, variation exists in the neurosurgical management of TBI within an otherwise homogeneous setting. This variation supports the methodology of the international Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) initiative, and shaped the Dutch Neurotraumatology Quality Registry (Net-QuRe) initiative.

Stroke is one of the most devastating vascular diseases in the world as it is responsible for almost five million deaths per year. Almost 90% of all strokes are ischemic and mainly due to atherosclerosis, cardiac embolism and small-vessel disease. Intracerebral or subarachnoid hemorrhage can lead to hemorrhagic stroke, which usually has the poorest prognosis. Cerebrolysin is a peptide preparation which mimics the action of a neurotrophic factor, protecting stroke-injured neurons and promoting neuroplasticity and neurogenesis. Cerebrolysin has been widely studied as a therapeutic tool for both ischemic and hemorrhagic stroke, as well as traumatic brain injury. In ischemic stroke, Cerebrolysin given as an adjuvant therapy to antiplatelet and rheologically active medication resulted in accelerated improvement in global, neurological and motor functions, cognitive performance and activities of daily living. Cerebrolysin was also safe and well tolerated when administered in patients suffering from hemorrhagic stroke. Traumatic brain injury leads to transient or chronic impairments in physical, cognitive, emotional and behavioral functions. This is associated with deficits in the recognition of basic emotions, the capacity to interpret the mental states of others, and executive functioning. Pilot clinical studies with adjuvant Cerebrolysin in the acute and postacute phases of the injury have shown faster recovery, which translates into an earlier onset of rehabilitation and shortened hospitalization time.

The influence of blood alcohol level (BAL) on outcome remains unclear. This study investigated the relationships between BAL, type and number of diffuse axonal injury (DAI), intraventricular bleeding (IVB) and 6-month outcome. This study reviewed 419 patients with isolated blunt traumatic brain injury. First, it compared clinical and radiological characteristics between patients with good recovery and disability. Second, it compared BAL among DAI lesions. Third, it evaluated the correlation between the BAL and severity of IVB, number of DAI and corpus callosum injury lesions. Regardless of BAL, older age, male gender, severe Glasgow Coma Scale score (<9), abnormal pupil, IVB and lesion on genu of corpus callosum were significantly related to disability. There were no significant differences between the BAL and lesions of DAI. Simple regression analysis revealed that there were no significant correlation between BAL and severity of IVB, number of DAI and corpus callosum injury lesions. Acute alcohol intoxication was not associated with type and number of DAI lesion, IVB and disability. This study suggested that a specific type of traumatic lesion, specifically lesion on genu of corpus callosum and IVB, might be more vital for outcome.

Objective To inverse-localize epileptiform cortical electrical activity recorded from severe traumatic brain injury (TBI) patients using electroencephalography (EEG). Methods Three acute TBI cases were imaged using computed tomography (CT) and multimodal magnetic resonance imaging (MRI). Semi-automatic segmentation was performed to partition the complete TBI head into 25 distinct tissue types, including 6 tissue types accounting for pathology. Segmentations were employed to generate a finite element method model of the head, and EEG activity generators were modeled as dipolar currents distributed over the cortical surface. Results We demonstrate anatomically faithful localization of EEG generators responsible for epileptiform discharges in severe TBI. By accounting for injury-related tissue conductivity changes, our work offers the most realistic implementation currently available for the inverse estimation of cortical activity in TBI. Conclusion Whereas standard localization techniques are available for electrical activity mapping in uninjured brains, they are rarely applied to acute TBI. Modern models of TBI-induced pathology can inform the localization of epileptogenic foci, improve surgical efficacy, contribute to the improvement of critical care monitoring and provide guidance for patient-tailored treatment. With approaches such as this, neurosurgeons and neurologists can study brain activity in acute TBI and obtain insights regarding injury effects upon brain metabolism and clinical outcome.

Traumatic brain injury (TBI) secondary to blast exposure is a common injury in the Global War on Terrorism, but little is known about the acute effects, recovery, pathophysiology, and neuropathology of blast-induced mild TBI (mTBI) in humans in a battlefield environment. Moreover, there is ongoing debate whether blast-induced mTBI is a different injury with a unique pathophysiology compared with mTBI from blunt trauma. In the case series reported here from Craig Joint Theater Hospital at Bagram Airfield, Afghanistan, 15 military service members with acute concussion/mTBI associated with blast exposure were evaluated within the first 24 hours after concussion and on days 2, 3, 5, and 7 with a Graded Symptom Checklist and a balance assessment, the Balance Error Scoring System. These data suggest that the recovery in blast-induced mTBI follows the pattern of recovery in sports-related concussion reported in The National Collegiate Athletic Association Concussion Study. In this retrospective case series, we provide the first description of the natural history of acute recovery in blast-induced mTBI, and we suspect, given our experience treating military service members, that further observations of the natural history of recovery in blast-induced mTBI will continue to mirror the natural history of recovery in sports concussion.

A 69-year-old woman was admitted to our hospital because of a sudden severe headache without a history of head trauma. CT and MRI revealed an acute subdural hematoma (ASDH) extending from the right interhemispheric space to the posterior fossa bilaterally, with a small amount of subarachnoid hemorrhage that was predominantly localized to the left side of the basal cistern. CT angiogram demonstrated a long protruding ruptured aneurysm at the junction of the right internal carotid and posterior communicating arteries (IC/PC AN) with a posteroinferior projection, associated with a small bleb located near the tentorial edge close to the ipsilateral posterior clinoid process, for which she received clipping surgery. Though rare, IC/PC AN could cause pure or nearly pure ASDH in the above-mentioned distribution. Therefore, in patients with such ASDH, especially without a history of head injury or precise information regarding the situation at the time of onset, urgent imaging evaluation and early intervention are essential to prevent devastating re-rupture events.

Respiratory neuromuscular impairment severity is known to predict weaning outcome among patients with cervical spinal cord injury; however, the impact of non-neuromuscular complications remains unexplored. This study was to evaluate possible neuromuscular and non-neuromuscular factors that may negatively impact weaning outcome. From September 2002 to October 2012, acute traumatic cervical spinal cord injury patients who had received mechanical ventilation for >48h were enrolled and divided into successful (n=54) and unsuccessful weaning groups (n=19). Various neuromuscular, non-neuromuscular factors and events during the intensive care unit stay were extracted from medical charts and electronic medical records. Variables presenting with a significant difference (p<0.2) between these two groups were included in the univariate analysis. Following univariate analysis, those significantly different variables (p<0.05) were subjected to multivariate logistic regression to identify independent predictors of unsuccessful weaning. Compared to successful weaning patients, unsuccessful weaning patients were older; more often had high level of cervical spinal cord injury (C1-3), lower pulse rates, and lower Glasgow Coma Scale score on admission, higher peak blood urea nitrogen, lower trough albumin, and lower trough blood leukocyte counts. Furthermore, unsuccessful weaning patients had a higher incidence of pneumonia, acute respiratory distress syndrome, shock and acute kidney injury during the intensive care unit stay. Multivariate logistic regression analysis revealed acute kidney injury and high level of cervical spinal cord injury were independent risk factors for failure of weaning. Importantly, patients with both risk factors showed a large increase in odds ratio for unsuccessful weaning from mechanical ventilation (p<0.001). The presence of acute kidney injury during the intensive care unit stay and high level of cervical spinal injury are two independent risk factors

Magnetic Resonance Imaging (MRI) has amply shown its usefulness for the evaluation of traumatic cranio-encephalic lesions, particularly those involving the posterior fossa, due to the absence of bone artifacts, the availability of multiplanar sections and the greater sensitivity as regards Computerized Tomography (C. T.). We present an MRI examination of an extra-axial hematoma of the clivus in a child with head trauma, not visible on C. T. scans.

Traumatic brain injury commonly has a result of a short window of opportunity between the period of initial brain injury and secondary brain injury, which provides protective strategies and can reduce damages of brain due to secondary brain injury. Previous studies have reported neuroprotective effects of extremely low-frequency electromagnetic fields. However, the effects of extremely low-frequency electromagnetic fields on neural damage after traumatic brain injury have not been reported yet. The present study aims to investigate effects of extremely low-frequency electromagnetic fields on neuroprotection after traumatic brain injury. Male Sprague-Dawley rats were used for the model of lateral fluid percussion injury, which were placed in non-electromagnetic fields and 15 Hz (Hertz) electromagnetic fields with intensities of 1 G (Gauss), 3 G and 5 G. At various time points (ranging from 0.5 to 30 h) after lateral fluid percussion injury, rats were treated with kainic acid (administered by intraperitoneal injection) to induce apoptosis in hippocampal cells. The results were as follows: (1) the expression of hypoxia-inducible factor-1α was dramatically decreased during the neuroprotective time window. (2) The kainic acid-induced apoptosis in the hippocampus was significantly decreased in rats exposed to electromagnetic fields. (3) Electromagnetic fields exposure shortened the escape time in water maze test. (4) Electromagnetic fields exposure accelerated the recovery of the blood-brain barrier after brain injury. These findings revealed that extremely low-frequency electromagnetic fields significantly prolong the window of opportunity for brain protection and enhance the intensity of neuroprotection after traumatic brain injury.

Topical application of lidocaine in wounds has been studied in combination with vasoconstrictive additives, but the effect without these additives is unknown. The objective was to examine use of lidocaine-soaked gauzes without vasoconstrictive agents, in traumatic wounds in adult patients, applied in triage. A prospective pilot study was performed during 6 weeks in the Emergency Department of a level 1 trauma center. Wounds of consecutive adult patients were treated with a nursing protocol, consisting of lidocaine hydrochloride administration directly into the wound and leaving a lidocaine-soaked gauze, until wound treatment. Primary outcome was need for infiltration anesthesia. Secondary outcomes were Numerical Rating Scale (NRS) pain scores, adverse events and patient and physician satisfaction. Forty patients with a traumatic wound were included, 85% male with a wound on the arm. Thirty-seven patients needed a painful procedure as wound treatment. When suturing was necessary, 77% required additional infiltration anesthesia. Mean NRS pain scores decreased from 3.3 to 2.2 after application of the lidocaine gauze. No adverse events were recorded. Of the patients, 60% were satisfied with use of the lidocaine gauzes, compared to 40% of physicians. Lidocaine hydrochloride (2%) gauzes without vasoconstrictive additives cannot replace infiltration anesthesia in traumatic wounds. Copyright © 2016 Elsevier Ltd. All rights reserved.

Dynamic rehabilitation has been suggested to be an important part of nonoperative treatment of acute Achilles tendon rupture that results in functional outcome and rerupture rates comparable with those of operative treatment. However, the optimal role of weight-bearing during early rehabilitation remains unclear. The purpose of this study was to compare immediate weight-bearing with non-weight-bearing in a nonoperative dynamic treatment protocol for Achilles tendon rupture. The study was conducted as a blinded, randomized, controlled, parallel superiority trial. Patients eighteen to sixty years of age were eligible for inclusion. Both groups were treated nonoperatively with controlled early motion. The intervention group was allowed full weight-bearing from day one, and the control group was non-weight-bearing for six weeks. The primary outcome was the Achilles tendon Total Rupture Score (ATRS) after one year. Secondary outcomes included heel-rise work, health-related quality of life, and the rerupture rate. Outcome assessors were blinded to the intervention. Thirty patients were randomized to each group; twenty-nine in the weight-bearing group and twenty-seven in the control group were analyzed. The only significant difference between the groups was better health-related quality of life in the weight-bearing group at twelve months (p = 0.009). The mean ATRS at twelve months was 73 in the weight-bearing group and 74 in the control group (p = 0.81). At twelve months, the total heel-rise work performed by the injured limb relative to that by the uninjured limb was 53% in the weight-bearing group and 58% in the control group (p = 0.37). There were three reruptures in the weight-bearing group and two in the control group (p = 1.0). The ATRS and heel-rise work results did not differ significantly between the groups. The rerupture rate was 9% overall, and both groups had substantial functional deficits in the injured limb compared with the uninjured limb. Immediate

Healthcare provider talk with parents in early acute care following children's severe traumatic brain injury (TBI) affects parents' orientations to these locales, but this connection has been minimally studied. This lack of attention to this topic in previous research may reflect providers' and researchers' views that these locales are generally neutral or supportive to parents' subsequent needs. This secondary analysis used data from a larger descriptive phenomenological study (2005-2007) with parents of children following moderate to severe TBI recruited from across the United States. Parents of children with severe TBI consistently had strong negative responses to the early acute care talk processes they experienced with providers, while parents of children with moderate TBI did not. Transcript data were independently coded using discourse analysis in the framework of ethnography of speaking. The purpose was to understand the linguistic and paralinguistic talk factors parents used in their meta-communications that could give a preliminary understanding of their cultural expectations for early acute care talk in these settings. Final participants included 27 parents of children with severe TBI from 23 families. We found the human constructed talk factors that parents reacted to were: a) access to the child, which is where information was; b) regular discussions with key personnel; c) updated information that is explained; d) differing expectations for talk in this context; and, e) perceived parental involvement in decisions. We found that the organization and nature of providers' talk with parents was perceived by parents to positively or negatively shape their early acute care identities in these locales, which influenced how they viewed these locales as places that either supported them and decreased their workload or discounted them and increased their workload for getting what they needed.
