    The effectiveness of ultrasound in diagnosing fractures of the ribs and sternum has been confirmed in the literature. The aim of our study was to present two case reports of patients with chest trauma history in whom ultrasound examination proved useful in the diagnostic process. The role of thoracic ultrasound in the diagnosis of ribs and sternal fractures is discussed as well. The authors conclude the following: 1) the examination was easy to perform and assess, and provided clinically useful conclusions; 2) due to the mobility of the ultrasound machine, the examination may be carried out outside of radiology departments, e.g. by the patient's bedside – in departments of surgery; 3) ultrasound should be the examination of choice after chest trauma and can be performed successfully by non-radiologist physicians.

    Abstract Blunt chest traumas are a clinical challenge, both for diagnosis and treatment. The use of Cardiovascular Magnetic Resonance can play a major role in this setting. We present two cases: a 12-year-old boy and 45-year-old man. Late gadolinium enhancement imaging enabled visualization of myocardial damage resulting from the trauma.

  4. Imaging of blunt chest trauma

    International Nuclear Information System (INIS)

    Blunt chest trauma is associated with high morbidity and mortality. Consequently, all patients should be evaluated radiologically after blunt chest trauma to allow timely and appropriate treatment. Conventional chest radiographs and computed tomography (CT) are proven modalities with which to evaluate patients after blunt chest trauma. Over the last several years extended focused assessment with sonography for trauma (eFAST) has gained increasing importance for the initial assessment of seriously injured patients. In the acute phase of severely injured patients eFAST examinations are helpful to exclude pneumothorax, hemothorax and hemopericardium. Chest radiographs may also be used to diagnose a pneumothorax or hemothorax; however, the sensitivity is limited and CT is the diagnostic modality of choice to evaluate severely injured patients.

    International Nuclear Information System (INIS)

    In western European countries most blunt chest traumas are associated with motor vehicle and sport-related accidents. In Switzerland, 39 of 10,000 inhabitants were involved and severely injured in road accidents in 1998. Fifty two percent of them suffered from blunt chest trauma. According to the Swiss Federal Office of Statistics, traumas represented in men the fourth major cause of death (4 %) after cardiovascular disease (38 %), cancer (28 %), and respiratory disease (7 %) in 1998. The outcome of chest trauma patients is determined mainly by the severity of the lesions, the prompt appropriate treatment delivered on the scene of the accident, the time needed to transport the patient to a trauma center, and the immediate recognition of the lesions by a trained emergency team. Other determining factors include age as well as coexisting cardiac, pulmonary, and renal diseases. Our purpose was to review the wide spectrum of pathologies related to blunt chest trauma involving the chest wall, pleura, lungs, trachea and bronchi, aorta, aortic arch vessels, and diaphragm. A particular focus on the diagnostic impact of CT is demonstrated. (orig.)

    A clotted haemothorax can develop any time after blunt chest trauma. Two cases are described in which late clotted haemothoraces developed which were treated by limited thoracotomy and evacuation of clots. Late clotted haemothorax may occur even in the absence of any abnormal initial clinical findings. Early detection and treatment is important to avoid the complications of fibrothorax and empyema with permanent pulmonary dysfunction. After blunt chest trauma patients should be advised to ret...

  11. Chest trauma in children: A local experience

    International Nuclear Information System (INIS)

    Chest trauma in childhood is relatively uncommon in clinical practice andhas been the subject of few reports in literature. This study was undertakento examine our experience in dealing with chest trauma in children. This wasa retrospective study of 74 children who sustained chest trauma and werereferred to King Fahd Hospital in Medina over a two-year period. The age,cause of injury, severity of injury, associated extrathoracic injuries,treatment and outcome were analyzed. The median age of patients was nineyears. Fifty-nine of them (80%) sustained blunt trauma in 62% of thechildren, gun shot wounds were seen in five and stab wounds in 10 children.Head injury was the most common injury associated with thoracic trauma andwas seen in 14 patients (19%) and associated intra-abdominal injuries wereseen in nine patients. Chest x-ray of the blunt trauma patients revealedfractured ribs in 24 children, pneumothorax in six, hemothorax in four,hemoneumothorax in three, and pulmonary contusions in 22 patients. Fifty onepercent of children were managed conservatively, 37% required tubethoracostomy, 8% were mechanically ventilated and 4% underwent thoractomy.The prevalence of chest trauma in children due to road traffic accidents ishigh in Saudi Arabia. Head injury is thought to be the most common associatedextrathoracic injuries, however, most of these patients can be managedconservatively. (author)

    Blunt thoracic trauma is frequently associated with further injuries (head and/or blunt abdominal trauma). The prognosis also depends on the concurrent injuries. The initial evaluation of an injured child is based on the chest X-ray and abdominal ultrasound examination. Additional information can be obtained by a CT scan in mediastinal injuries. (orig./MG)

    The incidence of chest trauma has increased significantly since the turn of the century especially in developed countries where rapid means of transportation has become part of daily life. Although gunshot wounds (GSWs) were the commonest causes of chest trauma in wartime, road traffic accidents (RTAs) have become the scourge of peacetime and modern civilization. Chest trauma is more common in males during the 2nd to the 5th decades of life with an average age of 40 years reducing their life expectancy by another 40 years at the most productive and active period of their lives. Despite improvement in ambulance service and rapid mobilization of victims from the scene of accident, about 10% of chest injured patients will die on the spot and another 5% die within an hour of reaching the hospital. Of the remaining 85%, five percent will require emergency thoracotomy for various reasons while 80% will respond to resuscitative measures and tube thoracostomy drainage alone. The primary aims in the management of chest trauma are prompt restoration of normal cardiorespiratory functions, control of haemorrhage, treatment of associated injuries and prevention of sepsis. Although the overall survival rate of trauma has improved in recent years, deaths are often due to airway obstruction, exsanguinating haemorrhage, flail chest, tension pneumothorax, cardiac tamponade and associated intracranial, intraabdominal and skeletal injuries.

  14. CT of blunt chest trauma in children

    International Nuclear Information System (INIS)

    While trauma is still the leading cause of death in the pediatric age range, it is surprising how little the CT appearances of pediatric chest injury have been investigated in the literature. We have reviewed the CT findings of blunt chest trauma in 44 children for whom chest CT examinations were requested to investigate the extent of intrathoracic injury. We noted a propensity for pulmonary contusions to be located posteriorly or posteromedially, and for them to be anatomically nonsegmental and crescentic in shape. This is possibly attributable to the relatively compliant anterior chest wall in children. The CT appearances of other major thoracic injuries are described, including pulmonary lacerations, pneumothoraces, malpositioned chest tubes, mediastinal hematomas, aortic injury, tracheobronchial injury, hemopericardium, and spinal injuries with paraspinal fluid collections. Children demonstrating findings incidental to the actual injury yet important to the subsequent therapy are also presented. We conclude that, in the event of clinically significant blunt chest trauma, the single supine chest examination in the trauma room is insufficient to adequately identify the extent of intrathoracic injury. With the exception of concern for aortic injury for which aortography is indicated, a dynamically enhanced CT scan of the thorax should be performed as clinically significant findings may result in altered therapy.

  15. Classification and management of chest trauma

    International Nuclear Information System (INIS)

    Objective: To classify the predominant pattern of injuries following blunt and penetrating chest trauma and to assess the adequacy of treatment strategies, complications and mortality associated with such injuries. Design: Descriptive study. Place and Duration of Study: Surgical Unit I, Holy Family Hospital, Rawalpindi, from December 2000 to December 2003. Patients and Methods: One hundred consecutive patients with thoracic trauma either blunt or penetrating, admitted in the ward were evaluated. Their injuries were classified, treatment strategies outlined and complications and mortality were documented on a specially-designed proforma. Results: Out of the 100 patients presenting in emergency, 44% presented with blunt and 56% with penetrating trauma. Pneumothorax was detected in 39% of the patients, hemopneumothorax in 29%, hemothorax in 12%, flail chest in 9%. Two had involvement of the heart and major vessels, 4% had injury to the diaphragm and 5% had multiple trauma. During treatment, 3% of all the patients were managed conservatively, 83% of patients required chest intubations, 6% needed ventilatory support and 8 % required thoracotomy. Complications were experienced in 28% of the patients of which 9% had pneumonias, 14% empyema and 5% suffered from wound infections. The overall mortality was 7%. Conclusion: This series showed the pattern of injuries following blunt and penetrating chest trauma. Furthermore, it was found that chest incubation and simple resuscitation was adequate for majority of the cases. (author)

    Full Text Available Cardiac contusion, usually caused by blunt chest trauma, has been recognized with increased frequency over the past decades. Traffic accidents are the most frequent cause of cardiac contusions resulting from a direct blow to the chest. Other causes of blunt cardiac injury are numerous and include violent fall impacts, interpersonal aggression, explosions, and various types of high-risk sports. Myocardial contusion is difficult to diagnose; clinical presentation varies greatly, ranging from lack of symptoms to cardiogenic shock and arrhythmia. Although death is rare, cardiac contusion can be fatal. We present a case of cardiac contusion due to blunt chest trauma secondary to a fall impact, which manifested as cardiogenic shock.

    Full Text Available Isolated tracheobronchial disruption is an uncommon injury usually associated with severe blunt thoracic trauma. We report a 14 year-old female case with avulsion of the left main bronchus occurring after blunt chest trauma due to a down fallen wall. A successful surgical repair of the totally avulsed left main bronchus was carried out. The postoperative course was uneventful with improvement in the respiratory status. The patient regained wellness within days in the intensive care unit, and the diagnosis of traumatic rupture of the left main bronchus was approved by bonchoscopy and the computerized tomography (CT scan of the chest. Surgical repair of the disrupted left main bronchus was accomplished 10 days from the admission and the bronchoscopic evaluation of the anastomosis and patency was achieved. The patient was discharged with her lung fully expanded on chest X-ray. The diagnosis and preoperative management of this uncommon post traumatic condition is discussed. We conclude that, in a patient with sustained severe blunt thoracic trauma, a high index of suspicion for trachea-bronchial disruptions must be maintained to detect these rare lesions. Skilful and early surgical treatment is required for proper management of such cases.

  20. Radiological diagnosis and therapy of chest pain

    International Nuclear Information System (INIS)

    The causes and localization of chest pain are numerous. They can derive from infections, traumas, or tumors. Possible sites of origin are: skeletal portions, vertebral column, ribs, and sternum, as well as mediastinum and pleura. In women, occurrence tends to be cyclic and affect the mamma region. Radiological diagnosis includes radiography, nuclear techniques as well as whole body computer-tomography. Radiation therapy is indicated in cases of mediastinal tumor formation. Radiation of painful osteolytic vertebral metastases and rib destructions proves to be an efficient palliative measure. (orig.)

    Full Text Available Aim:Childhood injuries are the leading cause of death in children and result in significant healthcare utilization. Trauma is the second most common cause of mortality in children aged 1-4 years and leading cause of death in children older than 4 years. Thoracic injury is the second most leading cause of death in traumatized children. Multisystemic injury is found in more than 50% of children with thoracic injuries most of which are secondary to blunt traumas. We planned this study to evaluate thorax trauma cases secondary to bicycle driving in childhood and to draw attention to the importance of the regulation of traffic rules, the education of bicycle drivers.Material and Methods:  A retrospective evaluation was performed in 17 pediatric patients admitted to the Department of Thoracic Surgery during 2006-2010 with a diagnosis of chest trauma due to bicycle driving. For every patient, a pediatric trauma score (PTS was calculated. Descriptive statistics were performed for PTS. Results; Eleven (64.70% cases were injured due to the tricycle accidents and six cases 6 (35.29% were injured due to the two-wheeled bicycle accidents. The most frequent thoracic pathologies included pulmonary contusion (41.2% and chest wall contusion (29.41%. Extrathoracic injuries were seen in 35.29%, the extremities (17.64% and abdomino pelvic (11.76% being the most commonly involved. Treatment consisted of symptomatic treatment in 12 patients (70.58%, tube thoracostomy in 2 patients (11.76%, and thoracotomy in 1 patient (5.9%. The morbidity was seen in 3 patients (17.64%. The mortality rate was 5.9% (n:1. The mean PTS of the cases who had additional system injuries were significantly worse than the cases who had isolated chest traumas Conclusions: The pediatric thorax has a greater cartilage content and incomplete ossification of the ribs.

    Given the heterogeneous nature of pediatric chest trauma, the optimal imaging approach is tailored to the specific patient. Chest radiography remains the most important imaging modality for initial triage. The decision to perform a chest computed tomography scan should be based on the nature of the trauma, the child\\'s clinical condition, and the initial radiographic findings, taking the age-related pretest probabilities of serious injury into account. The principles of as low as reasonably achievable and Image Gently should be followed. The epidemiology and pathophysiology, imaging techniques, characteristic findings, and evidence-based algorithms for pediatric chest trauma are discussed.

    2016-01-01

    Full Text Available Chest trauma is one of the important causes of mortality and morbidity in pediatric trauma patients. The complexity, magnitude, and type of lung injury make it extremely challenging to provide optimal oxygenation and ventilation while protecting the lung from further injury due to mechanical ventilation. Independent lung ventilation is used sporadically in these patients who do not respond to these conventional ventilatory strategies using double-lumen endotracheal tubes, bronchial blocker balloons, etc. However, this equipment may not be easily available in developing countries, especially for pediatric patients. Here, we present a case of severe chest trauma with pulmonary contusion, flail chest, and bronchopleural fistula, who did not respond to conventional lung protective strategies. She was successfully managed with bronchoscopy-guided unilateral placement of conventional endotracheal tube followed by single lung ventilation leading to resolution of a chest injury.

    2007-04-01

    The aim of the present work was to assess the value of the semi-quantitative procalcitonine test (PCT) in diagnosis of purulent-septic complications of chest traumas, efficacy of the therapy carried out, and outcome prognosis. For this, 71 patients with chest traumas were enrolled in the study. Concentrations of PCT were assessed in dynamics using an immunochromatographic, semi-quantitative quick test. Semi-quantitative quick PCT test is highly sensitive diagnostic marker that can be used for the assessment of a chest trauma, infectious-septic complication severity, and efficiency of the therapy indicated. Thus, it can be successfully used for monitoring trauma therapy. PCT sensitivity during first 12 hrs of infectious-septic complication development is 2-3-times higher than that of routine methods for laboratory diagnostics, and even more sensitive that IL-6 and CRT, when we are dealing with combined chest traumas. PCT concentration increase is 4-times more frequent in gram-positive bacterial processes than in gram-negative ones. This has to be taken into account, when appropriate antibacterial treatment is selected for restricted infectious-septic complications. PMID:17525495

    Most mediastinal abscesses result from infections after thoracotomy, esophageal perforation or pene- trating chest trauma. This disease is rarely caused by closed blunt chest trauma. All previously reported such cases after closed blunt chest trauma presented with hematoma and sternal osteomyelitis resulting from sternal fracture. Here we report a 15-year-old sumo wrestler who presented with an anterior mediastinal abscess without any mediastinal fracture. The mediastinal abscess resulted from the hematogenous spread of Staphylococcus aureus to a hematoma that might have been caused by a closed blunt chest trauma incurred during sumo wrestling exercises.

    Coronary artery injury is a rare complication following blunt chest trauma (BCT), and can be fatal. Here we report findings on postmortem selective coronary angiography of right coronary artery rupture after an assault involving blunt trauma to the chest. A woman in her 60s died after her son stomped on her chest. There were no appreciable signs of injury on external examination, and cause of death could not be determined by postmortem computed tomography (PMCT). Internal findings indicated that an external force had been applied to the anterior chest, as evidenced by subcutaneous hemorrhage and pericardial and cardiac contusions. Postmortem coronary angiography revealed irregularity of the intima and of the fat tissue surrounding the proximal part of the right coronary artery associated with a local filling defect. Histopathological examination suggested coronary rupture with dissection of the tunica media and compression of the lumen cavity. The key points in the present case are that no fatal injuries could be determined on external examination, and the heart and coronary artery injuries were not evident on PMCT. Criminality might be overlooked in such cases, as external investigation at the crime scene would be inadequate and could result in a facile diagnosis of cause of death. This is the first report of coronary artery rupture with dissection that was detected by CT coronary angiography, and provides helpful findings for reaching an appropriate decision both forensically and clinically.

    Full Text Available Delayed hemothorax in blunt chest trauma is described as a late presentation of hemothorax after a normal chest X-ray on admission. To detect this clinical entity a repeat chest X-ray is advised after six hours, especially when the first radiograph reveals rib or thoracic vertebral fractures or any significant injury to the thoracic viscera. However, this repeats chest X-ray examination is often not done in patients in whom a significant thoracic trauma has been excluded in the primary and secondary survey. Here, we discuss a case of massive delayed hemothorax after 16 hours of the blunt chest trauma despite a near normal admission chest X-ray and absence of significant chest trauma in the primary and secondary surveys.

    Abstract Cardiac injury occasionally occurs as a result of blunt chest trauma. Most cardiac complications in chest trauma are due to myocardial contusion rather than direct damage to the coronary arteries. However, traumatic coronary injury has been reported, and a variety of underlying pathophysiological mechanisms have been proposed. We present a 26 year old patient presenting with an acute coronary syndrome as a consequence of a soccer-shot impact to the chest. CMR showed apical inferior i...

    The majority of blunt chest injuries are minor contusions or abrasions; however, life-threatening injuries, including tension pneumothorax, hemothorax, and aortic rupture can occur and must be recognized early. This review focuses on the diagnosis, management, and disposition of patients with blunt injuries to the ribs and lung. Utilization of decision rules for chest x-ray and computed tomography are discussed, along with the emerging role of bedside lung ultrasonography. Management controversies presented include the limitations of needle thoracostomy us¬ing standard needle, chest tube placement, and chest tube size. Finally, a discussion is provided related to airway and ventilation management to assist in the timing and type of interventions needed to maintain oxygenation. PMID:27177417

    The aim of the study was to determine the frequency of different injuries caused by penetrating chest traumas, and also the cause and type of trauma and its accompanying injuries. This is a cross-sectional descriptive study, carried out on all patients referred to the emergency room of Shahid Bahonar Hospital, Kerman, from March 2000 to September 2008, due to penetrating chest trauma. The required information including age, sex, cause of trauma, type and site of injury, and accompanying injury was obtained and used to fill out a questionnaire and then was analyzed. 828 patients were included in the study; most of them were in the age range of 20-29. Of the patients, 97.6 % were males. The most frequent cause of trauma was stabbing, and the most frequent injuries following the trauma were pneumothorax and hemothorax. Orthopedic trauma was the most frequent accompanying injury. The most commonly used diagnostic method was plain chest radiography. In 93 % of the patients, the chest tube was placed and thoracotomy was performed for 97 % of the patients. Shahid Bahonar Hospital is a referral Trauma Centre and treats large number of chest trauma patients. Most patients need only chest tube placement as a definitive treatment. PMID:26246700

  19. Acute diaphragmatic paralysis caused by chest-tube trauma to phrenic nerve

    International Nuclear Information System (INIS)

    A 31/2-year-old child developed unilateral diaphragmatic paralysis after chest drain insertion. Plain chest X-ray demonstrated paravertebral positioning of the chest-tube tip, and magnetic resonance imaging revealed hematomas in the region of the chest-tube tip and the phrenic nerve fibers. The trauma to the phrenic nerve was apparently secondary to malposition of the chest tube. This is a rare complication and has been reported mainly in neonates. Radiologists should notify the treating physicians that the correct position of a chest drain tip is at least 2 cm distant from the vertebrae. (orig.)

    Chest CT after pediatric trauma is frequently performed but its clinical impact, particularly with respect to surgical intervention, has not been adequately evaluated. To assess the impact of chest CT compared with chest radiography on pediatric trauma management. Two hundred thirty-five consecutive pediatric trauma patients who had both chest CT and radiography were identified. Images were reviewed and findings were categorized and correlated with subsequent chest interventions, blinded to final outcome and management. Of the 235 children, 38.3% (90/235) had an abnormal chest radiograph and 63.8% (150/235) had an abnormal chest CT (P < 0.0001). Chest interventions followed in 4.7% (11/235); of these, the findings could be made 1 cm above the dome of the liver in 91% (10/11). Findings requiring chest intervention included pneumothorax (PTX) and vertebral fractures. PTX was found on 2.1% (5/235) of chest radiographs and 20.0% (47/235) of chest CTs (P < 0.0001); 1.7% (4/235) of the children received a chest tube for PTX, 0.85% (2/235) seen on chest CT only. Vertebral fractures were present in 3.8% of the children (9/235) and 66.7% (6/9) of those cases were treated with spinal fusion or brace. There were no instances of mediastinal vascular injury. Most intrathoracic findings requiring surgical management in our population were identified in the lower chest and would be included in routine abdominopelvic CT exams; this information needs to be taken into consideration in the diagnostic algorithm of pediatric trauma patients.

    To explore the effect of seawater immersion on serum osmotic pressure and electrolytes balance following chest trauma in dogs. Methods: Twenty-five healthy adult dogs were used in the experiment. A canine model of right open pneumothorax was established by chest puncturing on all animals. Animals were divided into three groups: a control group (n = 10) with chest trauma without any immersion;a seawater group ( n = 10) immersed in seawater after chest trauma and a normal saline group ( n = 5 ) immersed in normal saline solution following chest trauma. Blood samples were taken at different time intervals to determine plasma osmotic pressure and electrolytes. The hemodynamic changes were also recorded. Results: Mortality in the seawater group was much higher than that of the control group and the normal saline group. The mean survival time in the seawater group lasted only 45 minutes, while in the control group and the normal saline group the average survival time was more than 4 hours (P < 0.01 ). One of the most important causes of death was hypernatremia and high osmolality. Severe electrolytes imbalance was observed in seawater group.Hypernatremia and high osmolality were the most significant factors of high mortality in the seawater group. Conclusions: Seawater immersion after chest trauma appears to be associated with severe electrolyte imbalance as well as high osmotic pressure, These may be the risk factors leading to fatal outcome.

  7. Evidence-based diagnosis of abdominal trauma

    International Nuclear Information System (INIS)

    Abdominal trauma is a common cause of death particularly in patients up to 40 years of age. In order to reduce mortality a rapid radiologic diagnosis is essential. At present, sonography plays a role only in the evaluation of minor trauma and as a ''focused assessment with sonography for trauma'' (FAST) to clarify free intraperitoneal fluid immediately on admittance in severely injured patients. However, computed tomography has proven to be a potent tool for the triage of patients with abdominal trauma, because, based on the results of the CT scan, patients can be referred for laparotomy or safely classified for ''wait and see'' treatment. Therapeutic decisions are largely based on injury severity scores and the radiologist must be familiar with them as well as with the associated therapeutic consequences. (orig.)

    The purpose of this study was to derive parameters that predict which high-energy blunt trauma patients should undergo computed tomography (CT) for detection of chest injury. This observational study prospectively included consecutive patients ({>=}16 years old) who underwent multidetector CT of the chest after a high-energy mechanism of blunt trauma in one trauma centre. We included 1,047 patients (median age, 37; 70% male), of whom 508 had chest injuries identified by CT. Using logistic regression, we identified nine predictors of chest injury presence on CT (age {>=}55 years, abnormal chest physical examination, altered sensorium, abnormal thoracic spine physical examination, abnormal chest conventional radiography (CR), abnormal thoracic spine CR, abnormal pelvic CR or abdominal ultrasound, base excess <-3 mmol/l and haemoglobin <6 mmol/l). Of 855 patients with {>=}1 positive predictors, 484 had injury on CT (95% of all 508 patients with injury). Of all 192 patients with no positive predictor, 24 (13%) had chest injury, of whom 4 (2%) had injuries that were considered clinically relevant. Omission of CT in patients without any positive predictor could reduce imaging frequency by 18%, while most clinically relevant chest injuries remain adequately detected. (orig.)

  9. Differential diagnosis of solitary pulmonary nodule : chest radiography vs CT

    International Nuclear Information System (INIS)

    The purpose of this study was to compare the diagnostic accuracies of chest radiographs and chest CT in the diagnosis of a solitary pulmonary nodule(SPN), and to determine the role of CT and CT findings which aid in the differential diagnosis of nodules. A retrospective study was done on 54 patients in whom SPN was found on chest radiographs and chest CT was carried out. The study involved 25 benign and 29 malignant nodules, confirmed histopathologically and clinically. Chest radiographs and CT scans were reviewed separately in randomized order by two chest radiologists who for each film listed the three most likely diagnoses in descending order. The radiologists recorded the confidence value of the most probable diagnosis, and also the marginal and internal characteristics of nodules and their size, as nodules seen on chest CT scans. Diagnostic rates in the differential diagnosis of benign and malignant nodules were 65.7% by radiography and 77.8% by CT. Correct first-choice diagnosis was by radiography in 30.6% of cases, and by CT in 41.7%. Using radiographs, and the correct diagnosis was among the top-three choices in 61.1% of cases;with CT, the corresponding figure was 76.8%. Overall, a confident diagnosis was reached more often with the CT(41.7%) than with the chest radiograph(21.4%); diagnostic accuracy was 60.0% and 52.2%, respectively. CT findings which imply a benign nodule include smooth margins and diffuse internal calcifications, whereas marginal lobulations, air-bronchograms, internal low density without cavitation, eccentric calcifications, and large size suggest malignancy. We found that CT findings such as well-defined margins, spiculations, pleural tail or internal homogeneity did not contribute in the differentiation between benign and malignant nodules. CT is superior to chest radiography in the differential diagnosis of the solitary pulmonary nodule. Using CT, diagnosis was accurate and made with a high level of confidence, especially with the

    BACKGROUND: The appropriate sequence of different imagings and indications of thoracic computed tomography (TCT) in evaluating chest trauma have not yet been clarified at present. The current study was undertaken to determine the value of chest X-ray (CXR) in detecting chest injuries in patients with blunt trauma. METHODS: A total of 447 patients with blunt thoracic trauma who had been admitted to the emergency department (ED) in the period of 2009–2013 were retrospectively reviewed. The patients met inclusion criteria (age>8 years, blunt injury to the chest, hemodynamically stable, and neurologically intact) and underwent both TCT and upright CXR in the ED. Radiological imagings were re-interpreted after they were collected from the hospital database by two skilled radiologists. RESULTS: Of the 447 patients, 309 (69.1%) were male. The mean age of the 447 patients was 39.5±19.2 (range 9 and 87 years). 158 (35.3%) patients were injured in motor vehicle accidents (MVA). CXR showed the highest sensitivity in detecting clavicle fractures [95%CI 78.3 (63.6–89)] but the lowest in pneuomediastinum [95%CI 11.8 (1.5–36.4)]. The specificity of CXR was close to 100% in detecting a wide array of entities. CONCLUSION: CXR remains to be the first choice in hemodynamically unstable patients with blunt chest trauma. Moreover, stable patients with normal CXR are candidates who should undergo TCT if significant injury has not been ruled out. PMID:27006740

    Objective To assess the diagnostic value of chest radiographs in patients presenting to a busy inner-city Emergency Department with subsequently proven acute aortic dissection. Methods A retrospective review of initial chest radiographs and charts of patients with the confirmed diagnosis of acute aortic dissection was done for a period of 5 years from 1998 to 2003. A comparison was made between the initial readings of chest radiographs prior to confirmation of the aortic dissection, and a retrospective review of the same radiographs by two board-certified radiologists with special attention to the classic findings of acute aortic dissection identifiable on plain films. Results The charts of nine patients (four men, five women) with proven acute aortic dissection were reviewed. All nine patients were suspected of having acute aortic dissection based on presenting history and symptoms of chest pain (66% ), migratory pain (89% ), back pain (89% ), and the abruptness of onset of pain (89% ). Initial plain portable chest X-rays were obtained in the Emergency Department in all nine patients. Six of nine (67%) radiographs were read as normal, while three (33%) demonstrated a widened mediastinum (> 8.0cm), two (22%) showed an abnormal aortic contour, with one ( 11% ) displaying an apical cap. Confirmation of the diagnosis was obtained with either a spiral CT angiogram or transesophageal echocardiography (TEE). All nine plain radiographs were retrospectively reviewed by two board-certified radiologists aware of the diagnosis of acute dissection without a change in the readings. Conclusions Plain portable chest radiographs are of limited usefulness for the screening of acute aortic dissection. Further radiologic evaluation should be dictated by the clinical presentation and an awareness of the low sensitivity of portable chest X- rays.

Methods: It was a descriptive and observational study of patients with chest trauma who were admitted between January 2013 and May 2014. The variables were evaluated and the results according to management with closed thoracostomy in patients with thoracic trauma was determined. Univariate analysis was performed and measures of central tendency were calculated. Results: In total 240 patients were analyzed. Among them, 10.4% (25) developed posttraumatic empyema. In patients who developed empyema, the mean age was 34.2 years, and the mean injury severity score was 20.6. It was identified as a risk factor closed chest trauma in 68%(17) and 84%coagulated hemothorax trauma. Empyema management thoracoscopy was in 100%of cases. Conclusions: The posttraumatic empyema is a complication that occurs in patients with thoracic trauma. One of the most important risk factors is coagulated hemothorax which could be identified and treated in time to avoid comorbidities during hospital stay.

    Chest radiographs are the most common exam in radiology. They are essential for the management of various diseases associated with high mortality and morbidity and display a wide range of findings, many of them subtle. In this survey we identify a number of areas beyond pulmonary nodules that could benefit from computer-aided detection and diagnosis (CAD) in chest radiography. These include interstitial infiltrates, catheter tip detection, size measurements, detection of pneumothorax and detection and quantification of emphysema. Recent work in these areas is surveyed, but we conclude that the amount of research devoted to these topics is modest. Reasons for the slow pace of CAD development in chest radiography beyond nodules are discussed.

  17. Mechanisms and Clinical Management of Ventricular Arrhythmias following Blunt Chest Trauma

    Directory of Open Access Journals (Sweden)

    Daniel H. Wolbrom

    2016-01-01

    Full Text Available Nonpenetrating, blunt chest trauma is a serious medical condition with varied clinical presentations and implications. This can be the result of a dense projectile during competitive and recreational sports but may also include other etiologies such as motor vehicle accidents or traumatic falls. In this setting, the manifestation of ventricular arrhythmias has been observed both acutely and chronically. This is based on two entirely separate mechanisms and etiologies requiring different treatments. Ventricular fibrillation can occur immediately after chest wall injury (commotio cordis and requires rapid defibrillation. Monomorphic ventricular tachycardia can develop in the chronic stage due to underlying structural heart disease long after blunt chest injury. The associated arrhythmogenic tissue may be complex and provides the necessary substrate to form a reentrant VT circuit. Ventricular tachycardia in the absence of overt structural heart disease appears to be focal in nature with rapid termination during ablation. Regardless of the VT mechanism, patients with recurrent episodes, despite antiarrhythmic medication in the chronic stage following blunt chest injury, are likely to require ablation to achieve VT control. This review article will describe the mechanisms, pathophysiology, and treatment of ventricular arrhythmias that occur in both the acute and chronic stages following blunt chest trauma.

    The radiologic changes of the chest X-ray of 270 newborns with respiratory distress were analyzed. In cases of Hyaline Membranes the chest X-Ray showed finely granular evenly disseminated structures combined with signs of hypoventilation. Localized, patchy, streaky, homogenous and reticulonodular shadows were found in cases of pneumonia and hemorrhage. Hyperinflation were an additional sign for an inflammatory disease. This symptom was also demonstrated in pulmonary bleeding, but was less common. The bilateral interstitial augmentation of the pulmonary structure in combination with cardiomegaly was mainly a symptom for cardial insufficiency and transient tachypnea. The differentiation between fine granular and reticulo-nodular structures should create no problem if the chest X-ray is of good quality. Extrapulmonary air collections were found in a high percentage in the course of artificial ventilation as a consequence of the 'baro-trauma'. The radiologic diagnosis of BPD was no problem. The value of the chest X-ray lies in the demonstration of a pulmonary cause for the respiratory distress, in the demonstration of complications and in the radiological observation of the disease.

    Cigarette smoking (CS) aggravates post-traumatic acute lung injury and increases ventilator-induced lung injury due to more severe tissue inflammation and apoptosis. Hyper-inflammation after chest trauma is due to the physical damage, the drop in alveolar PO2, and the consecutive hypoxemia and tissue hypoxia. Therefore, we tested the hypotheses that 1) CS exposure prior to blunt chest trauma causes more severe post-traumatic inflammation and thereby aggravates lung injury, and that 2) hyperox...

  1. Using 99mTc-DTPA radioaerosol inhalation lung scan as compared with computed tomography to detect lung injury in blunt chest trauma

    International Nuclear Information System (INIS)

    Detection of pulmonary contusion in patients with blunt chest trauma is very important so as to commence therapy immediately to avoid irreversible damage. The purpose of our study was to evaluate the efficacy of technetium-99m diethylene triamine penta-acetic acid (99mTc-DTPA) aerosol inhalation lung scintigraphy in comparison with chest computed tomography (CT) in the diagnosis of pulmonary contusion at acute blunt chest trauma. Twenty-nine patients with isolated blunt chest trauma were referred to the emergency department of our hospital, and nine healthy people participated in this study. Sixteen patients who had pulmonary contusion on CT scans were referred to as group 1, and 13 patients who had normal CT scans as group 2. Nine healthy people comprised a control group. 99mTc-DTPA aerosol inhalation lung scintigraphy was performed on the first day in all patients. The mean half time (T1/2) and penetration index values of 99mTc-DTPA clearance were significantly lower in groups 1 and 2 compared with the control group. Among the three groups, there were no significant differences in arterial blood gas analysis except for PO2. The mean T1/2 value of 99mTc-DTPA clearance did correlate with PO2 values but not with pH, PCO2, or HCO3 values. 99mTc-DTPA radioaerosol inhalation lung imaging may serve as a useful adjunct and supportive method to chest CT scanning for detecting mild pulmonary contusion.

It measures the output error and calculates the gradient of the error and adjusting the ANN weight moving along the descending gradient direction. Back propagation is used to learn and store by mapping relations of inputoutput model. A genetic algorithm is having a random probability distribution or pattern that may be analyses statistically but may not be predicted precisely. Genetic algorithm is an iterative procedure that generates new population for individual from the old one. In my paper I am proposing to implement the back propagation algorithm and genetic algorithm to compare the output accuracy percent for medical diagnosis on various chest diseases (Asthme, tuberculosis, lung cancer, pneumonia

    The purpose of this retrospective study was to determine the value of contrast-enhanced helical CT for detecting and managing acute thoracic aortic injury (ATAI). Between June 1995 and February 2000, 1419 consecutive chest CT examinations were performed in the setting of major blunt trauma. The following CT findings were considered indicative of ATAI: intimal flap; pseudoaneurysm; contour irregularity; lumen abnormality; and extravasation of contrast material. On the basis of these direct findings no further diagnostic investigations were performed. Isolated mediastinal hematoma on CT scans was considered an indirect sign of ATAI: In these cases, thoracic aortography was performed even if CT indicated normal aorta. Seventy-seven patients had abnormal CT scans: Among the 23 patients with direct CT signs, acute thoracic aortic injuries was confirmed at thoracotomy in 21. Two false-positive cases were observed. The 54 remaining patients had isolated mediastinal hematoma without aortic injuries at CT and corresponding negative angiograms. The 1342 patients with negative CT scans were included in the 8-month follow-up program and did not show any adverse sequela based on clinical and radiographic criteria. Contrast-enhanced helical CT has a critical role in the exclusion of thoracic aortic injuries in patient with major blunt chest trauma and prevents unnecessary thoracic aortography. Direct CT signs of ATAI do not require further diagnostic investigations to confirm the diagnosis: Isolated aortic bands or contour vessel abnormalities should be first considered as possible artifacts or related to non-traumatic etiologies especially when mediastinal hematoma is absent. In cases of isolated mediastinal hematoma other possible sources of bleeding should be considered before directing patients to thoracic aortography. (orig.)

    Full Text Available Abstract Background Airway clearance is frequently needed by patients suffering from blunt chest wall trauma. High Frequency Chest Wall Oscillation (HFCWO has been shown to be effective in helping to clear secretions from the lungs of patients with cystic fibrosis, bronchiectasis, asthma, primary ciliary dyskinesia, emphysema, COPD, and many others. Chest wall trauma patients are at increased risk for development of pulmonary complications related to airway clearance. These patients frequently have chest tubes, drains, catheters, etc. which could become dislodged during HFCWO. This prospective observational study was conducted to determine if HFCWO treatment, as provided by The Vest™ Airway Clearance System (Hill-Rom, Saint Paul, MN, was safe and well tolerated by these patients. Methods Twenty-five blunt thoracic trauma patients were entered into the study. These patients were consented. Each patient was prescribed 2, 15 minute HFCWO treatments per day using The Vest® Airway Clearance System (Hill-Rom, Inc., St Paul, MN. The Vest® system was set to a frequency of 10–12 Hz and a pressure of 2–3 (arbitrary unit. Physiological parameters were measured before, during, and after treatment. Patients were free to refuse or terminate a treatment early for any reason. Results No chest tubes, lines, drains or catheters were dislodged as a result of treatment. One patient with flail chest had a chest tube placed after one treatment due to increasing serous effusion. No treatments were missed and continued without further incident. Post treatment survey showed 76% experienced mild or no pain and more productive cough. Thirty days after discharge there were no deaths or hospital re-admissions. Conclusion This study suggests that HFCWO treatment is safe for trauma patients with lung and chest wall injuries. These findings support further work to demonstrate the airway clearance benefits of HFCWO treatment.

AIMS: W e evaluated electrocardiogram (ECG, cardiac troponin - I (Tn - I and creatin e kinase - MB (CK - MB levels to diagnose myocardial contusion (MC in chest trauma patients. SETTINGS AND DESIGN: A total of 50 chest trauma cases were randomly included in the study. Patients with a history of ischemic heart disease or myocardial infarction and/or treatment with anti - anginal or antihypertensive drugs were excluded. MATERIAL AND METHODS: ECG, CK - MB, c reatinine phosphokinase (CPK, and Tn - I were recorded at admission and repeated at 24 and 72 hours. Patients were grouped as suspected or non - suspected MC group based on any of the following: Abnormal ECG; CK - MB > 50 U/L; CK - MB/CPK ratio > 5; Tn - I > 1.5 ng /ml. Suspected MC group patients were sub - grouped as significant MC group: If they had - abnormal echocardiographic findings such as regional wall motion abnormalities, regurgitant lesions; unexplained hemodynamic instability and shock with systolic blood pressur e <90mmHg; patients unresponsive to fluid resuscitation in spite of replacement of estimated blood loss; or patients requiring vasopressor for cardiogenic shock. STATISTICAL ANALYSIS: Student’s t - test, Z - test and sensitivity analysis were performed for statistical analysis . RESULTS: Of 50 patients, 44 belonged to suspected MC group; 15 of them had significant MC. ECG was the most sensitive (93.3% indicator of MC whereas Tn - I showed high specificity (86.20% for MC. CONCLUSIONS: Troponin - I is a speci fic marker of MC while ECG is a sensitive diagnostic tool.

    Full Text Available A morbidly obese male who sustained blunt trauma chest with bilateral pneumothorax was referred to the intensive care unit for management of his condition. Problems encountered in managing the patient were gradually increasing hypoxemia (chest trauma with multiple rib fractures with lung contusions and difficult mask ventilation and intubation (morbid obesity, heavy jaw, short and thick neck. We performed awake endotracheal intubation using an intubating laryngeal mask airway (ILMA size 4 and provided mechanical ventilation to the patient. This report suggests that ILMA can be very useful in the management of difficult airway outside the operating room and can help in preventing adverse events in an emergency setting.

    International Nuclear Information System (INIS)

    Objectives: To investigate the effects of aprotinin, on blood gasses, oxidant-antioxidant status, and lung histopathology in an experimental bilateral blunt chest trauma model. Methods: Conducted at the Experimental Animal Laboratory of Meram Medical School at Selcuk University, Konya, Turkey, the study comprised 21 New Zealand female albino rabbits who were divided into three groups. Trauma was applied on the sham and aprotinin groups, which was administered intravenous Aprotinin 20.000 U/kg. Arterial blood samples were obtained from all rabbits at hours 0, 3, 24, and 96. At hour 96 after trauma, all rabbits were sacrificed using the decapitation method, and then blood and lung tissue samples were obtained. Blood nitric oxide, malondialdehyde and blood gas measurements were made. Histopathological changes in the lung were examined with a light microscope. Results: While no positive effect of aprotinin was observed on nitric oxide malondialdehyde and partial pressure of carbon dioxide values, it was seen to have an increasing effect on partial oxygen pressure level. Aprotinin had a partial effect on lung histopathology. Conclusion: Aprotinin was determined to have a positive effect on PO/sub 2/ levels. We could not find any positive effects especially on alveolar haemorrhage. (author)

    Full Text Available The chest radiograph (CXR is considered a key diagnostic tool for pediatric tuberculosis (TB in clinical management and endpoint determination in TB vaccine trials. We set out to compare interrater agreement for TB diagnosis in western Kenya. A pediatric pulmonologist and radiologist (experts, a medical officer (M.O, and four clinical officers (C.Os with basic training in pediatric CXR reading blindly assessed CXRs of infants who were TB suspects in a cohort study. C.Os had access to clinical findings for patient management. Weighted kappa scores summarized interrater agreement on lymphadenopathy and abnormalities consistent with TB. Sensitivity and specificity of raters were determined using microbiologically confirmed TB as the gold standard (n=8. A total of 691 radiographs were reviewed. Agreement on abnormalities consistent with TB was poor; k=0.14 (95% CI: 0.10–0.18 and on lymphadenopathy moderate k=0.26 (95% CI: 0.18–0.36. M.O [75% (95% CI: 34.9%–96.8%] and C.Os [63% (95% CI: 24.5%–91.5%] had high sensitivity for culture confirmed TB. TB vaccine trials utilizing expert agreement on CXR as a nonmicrobiologically confirmed endpoint will have reduced specificity and will underestimate vaccine efficacy. C.Os detected many of the bacteriologically confirmed cases; however, this must be interpreted cautiously as they were unblinded to clinical features.

    1996-07-01

    A total of 160 patients underwent emergency room thoracotomy (ERT) from January 1988 to June 1995. There were 142 male and 18 female patients with ages ranging from 15 months to 72 years old with a mean age of 31 years. Blunt trauma was the mechanism of injury in 11 patients; none of them survived, and they were excluded from further analysis. A total of 149 patients sustained penetrating trauma, 111 patients gunshot wounds, and 38 patients stab wounds. A total of four patients survived to discharge for an overall survival rate of 2.7 per cent. All four were victims of a stab wound and were neurologically intact at the time of discharge. Special interest was placed in classifying patients according to their physiologic status both at the scene and on arrival to the emergency department. Class I, patients with no signs of life; Class II, Agonal--patients in electromechanical dissociation/pulseless electrical activity with no palpable pulse or blood pressure; Class III, Profound Shock--patients with blood pressure less than 60 mm Hg; and Class IV, Mild Shock--patients with blood pressure between 60 and 90 mm Hg. 122 patients (89%) fitted the criteria for Scene Classes I and II. None of these patients improved or responded to prehospital resuscitation to be moved up to Emergency Department Classes III or IV, and all of them died. Of the four survivors, three were in Scene Class III and one was in Scene Class IV. This study confirms a previous report that, overall, ERT has a very low survival rate. ERT should be abandoned in patients sustaining blunt trauma, and should probably be limited to patients sustaining penetrating chest injuries who fall into the physiologic Classes III or IV at the scene.

    Abdominal trauma is a common cause of death particularly in patients up to 40 years of age. In order to reduce mortality a rapid radiologic diagnosis is essential. At present, sonography plays a role only in the evaluation of minor trauma and as a 'focused assessment with sonography for trauma' (FAST) to clarify free intraperitoneal fluid immediately on admittance in severely injured patients. However, computed tomography has proven to be a potent tool for the triage of patients with abdominal trauma, because, based on the results of the CT scan, patients can be referred for laparotomy or safely classified for 'wait and see' treatment. Therapeutic decisions are largely based on injury severity scores and the radiologist must be familiar with them as well as with the associated therapeutic consequences. (orig.) [German] Das Trauma des Abdomens ist insbesondere bei Patienten unter 40 Jahren eine haeufige Todesursache. Die rasche Erstellung aussagekraeftiger radiologischer Befunde ist unerlaesslich, um die Mortalitaet zu senken. Die Sonographie wird heute nur mehr bei Bagatelltraumen und als 'focused assessment with sonography for trauma' (FAST) zur Abklaerung freier intraperitonealer Fluessigkeit unmittelbar nach dem Eintreffen schwer verletzter Patienten verwendet. Hingegen hat die Radiologie mit der Multidetektorcomputertomographie (MDCT) ein geeignetes Instrument zur Verfuegung, um seine Rolle fuer die Triage zur operativen oder konservativen Behandlung von Patienten nach Trauma des Abdomens erfuellen zu koennen. Die therapeutischen Entscheidungen werden wesentlich von Verletzungsscores bestimmt, mit denen der Radiologe zusammen mit den sich daraus ergebenden Konsequenzen vertraut sein muss. (orig.)

    Full Text Available Katja Oshaug, Peder A Halvorsen, Hasse Melbye General Practice Research Unit, University of Tromsø, Tromsø, Norway Background: Although proven to be associated with bronchial obstruction, chest signs are not listed among cues that should prompt spirometry in the early diagnosis of chronic obstructive pulmonary disease (COPD in established guidelines. Aims: We aimed to explore how chest findings add to respiratory symptoms and a history of smoking in the diagnosis of COPD. Methods: In a cross-sectional study, patients aged 40 years or older, previously diagnosed with either asthma or COPD in primary care, answered questionnaires and underwent physical chest examination and spirometry. Results: Among the 375 patients included, 39.7% had forced expiratory volume in 1 second/forced vital capacity <0.7. Hyperresonance to percussion was the strongest predictor of COPD, with a sensitivity of 20.8, a specificity of 97.8, and likelihood ratio of 9.5. In multivariate logistic regression, where pack-years, shortness of breath, and chest findings were among the explanatory variables, three physical chest findings were independent predictors of COPD. Hyperresonance to percussion yielded the highest odds ratio (OR = 6.7, followed by diminished breath sounds (OR = 5.0, and thirdly wheezes (OR = 2.3. These three chest signs also gave significant diagnostic information when added to shortness of breath and pack-years in receiver operating-characteristic curve analysis. Conclusion: We found that chest signs may add to respiratory symptoms and a history of smoking in the diagnosis of COPD, and we conclude that chest signs should be reinstated as cues to early diagnosis of COPD in patients 40 years or older.

    Full Text Available Abstract Trauma-related thoracic compartment syndrome (TCS is a rare, life threatening condition that develops secondary to elevated intra-thoracic pressure and manifests itself clinically as significantly elevated airway pressures, inability to provide adequate ventilation and hemodynamic instability temporally related to closure of a thoracic surgical incision. TCS is exceedingly rare in the trauma population. We present a case of TCS following surgical repair of a stab wound injury that necessitated decompressive thoracotomy and peri-operative open-chest management.

    Penetrating chest trauma can be used as an indicator of violence in the country. We aimed to look at the changes in its incidence and management at a major trauma centre in the country. We also wanted to look at any effect of prehospital time on surgical intervention and outcome of the victim. In this retrospective descriptive study, we observed the presentation and management of 191 penetrating chest injury patients at a level II trauma hospital in Pakistan in the last 20 years. The study sample was divided into two groups: Group 1, 1988-1998 and Group 2, 1999-2009. No significant change in incidence of trauma was observed between the two groups. The delay in the time between event and arrival showed an increase in the number of surgical procedures performed. Also the number of thoracotomies performed went up significantly in the second decade from 5.7 to 16.5% with a Pprehospital time, the greater the chances of surgery. Also seen was the increase in mortality as critical cases could make it to the hospital alive in recent times due to improved transportation services. PMID:20923826

    Full Text Available Traumatic coronary artery dissection is an uncommon cause of acute myocardial infarction (AMI. We report a case of blunt chest trauma resulting from a motorcycle collision causing ostial dissection of the left anterior descending (LAD artery in a 31-year-old previously healthy male. The patient also suffered from compound comminuted fractures of the humerus and ulna and severe liver laceration, which hampered both percutaneous and surgical acute revasularization. After a stormy hospital course, a bare metal stent was implanted to seal the LAD artery dissection. The patient was discharged in a stable condition and was followed-up for rehabilitation. This case report underscores the multidisciplinary approach in facing challenges encountered after rare sequelae of chest trauma.

    International Nuclear Information System (INIS)

    Common chest radiographic findings in trisomy-21 include multiple manubrial ossification centers (MMC), 11 rib pairs (11R), and a notably bell-shaped chest (BSC). These findings were compared in a sequential series of 881 newborns (first 48 hours of life) without chromosomal abnormalities and 30 newborns with trisomy-21. Logistic regression analysis indicates that the probability of trisomy-21 is 0.05% when none of these findings is present, 1.6% with MMC alone, 0.2% with 11R alone, 0.7% with BSC alone, 8.8% with MMC and 11R, 19.4% with MMC and BSC, 3.9% with 11R and BSC, and 58.4% if all three findings are present

    Full Text Available Esophageal rupture due to external blunt trauma is extremely rare in children. A-13-year old boy was admitted to emergency room with shortness of breath and abdominal pain. His history revealed fall down from 3 metres height, falling of a wooden block over chest, 4 hours before at home. Thoracic esophageal perforation was diagnosed at the 6th day of hospital stay. Surgical management was planned and right-sided  thoracotomy was performed at the 7th day after admission. The esophageal layers were closed primarily and separately after muscular and mucosal debridement. Reinforcement of the primary repair was done with pleural and intercostal muscle flaps. The esophagus was tied with absorbable sutures at proximal and distal parts of the perforation to block the esophageal passage. Gastrostomy and jejunostomy were performed for nutrition. We report here a successful management with primary repair of this esophageal perforation of late diagnosis.

  1. Detection of alveolar epithelial injury by 99mTc-DTPA radioaerosol inhalation lung scan following blunt chest trauma

    International Nuclear Information System (INIS)

    DTPA clearance rate is a reliable index of alveolar epithelial permeability, and is a highly sensitive marker of pulmonary epithelial damage, even of mild degree. In this study, 99mTc-DTPA aerosol inhalation scintigraphy was used to assess the pulmonary epithelial membrane permeability and to investigate the possible application of this permeability value as an indicator of early alveolar or interstitial changes in patients with blunt chest trauma. A total of 26 patients was chest trauma (4 female, 22 male, 31-80 yrs, mean age; 53±13 yrs) who were referred to the emergency department in our hospital participated in this study. Technetium-99m diethylene triamine pentaacetic acid (DTPA) aerosol inhalation scintigraphy was performed on the first and thirtieth days after trauma. Clearance half times (T1/2) were calculated by placing a mono-exponential fit on the curves. Penetration index (PI) was calculated on the first-minute image. On the first day, mean T1/2 value of the whole lung was 63±19 minutes (min), and thirtieth day mean T1/2 value was 67±21 min. On the first day, mean PI values of the lung and 30th day mean PI value were 0.60±0.05, and 0.63 ±0.05, respectively. Significant changes were observed in radioaerosol clearance and penetration indices. Following chest trauma, clearance of 99mTc-DTPA increased owing to breakdown of the alveolar-capillary barrier. This increase in the epithelial permeability of the lung appears to be an early manifestation of lung disease that may lead to efficient therapy in the early phase. (author)

  2. The diagnosis of pneumonia requires a chest radiograph (x-ray – yes, no or sometimes?

    2014-06-01

    Full Text Available Community-acquired pneumonia (CAP remains a common condition associated with considerable morbidity and mortality. Outcome is improved by early recognition and rapid institution of empirical antibiotic therapy. A number of international guidelines recommend a chest radiograph (x-ray is obtained when pneumonia is suspected; the argument forwarded is that chest radiographs are relatively inexpensive and enable pneumonia (lung consolidation to be confirmed or excluded. But, radiographs are not available in the community setting and introduce a delay in diagnosis and treatment. For these reasons, in mild CAP treated by primary care, guidelines suggest criteria for clinical diagnosis. However, there is debate as to whether clinical features alone are sufficiently reliable to support a diagnosis of CAP with some suggesting diagnostic precision is improved by chest radiographs. Conversely, several studies have demonstrated a lack of agreement in the interpretation of chest radiographs bringing their role as the ultimate arbiter of diagnosis into question. Below we debate the diagnostic role of the humble chest radiograph in the context of suspected CAP.

    Background: Images of myocardial perfusion taken during an episode of chest pain have been used for patients in the emergency department. Objective: To evaluate the operating characteristics of {sup 99m}Tc-Tetrofosmin scintigraphy during an episode of chest pain to exclude the diagnosis of cute myocardial infarction. Methods: One hundred and eight patients admitted with chest pain, or up to four hours after the end of symptoms and non diagnostic electrocardiogram, underwent resting scintigraphy and measurement of troponin I concentrations. Patients with a history of myocardial infarction (MI) were not excluded (24 patients). Troponin I concentrations were determined at admission and 6 hours later. Nuclear physicians performed a blind analysis of the images, and myocardial infarction was confirmed whenever troponin I level increase was three times that of the control. Results: Resting perfusion image was abnormal in all 6 patients with MI. Only 1 patient had a normal image and increased troponin levels. Fifty-five patients had positive images without MI, and 46 patients had normal images and troponin levels. The prevalence of the disease was 6.5%. The sensitivity and specificity of the resting images during an episode of chest pain to diagnose MI was 85.7% and 45.5%, respectively. The negative predictive value was 97.7%. Conclusion: Patients undergoing chest pain protocol with SPECT showed an excellent negative predictive value to exclude diagnosis of myocardial infarction. These results suggest that resting perfusion image is an important tool at the chest pain unit. (author)

  5. Efficient radiologic diagnosis of pelvic and acetabular trauma

    International Nuclear Information System (INIS)

    In spite of the widespread availability of CT scanners, conventional X-ray radiographs remain the basic imaging modality in patients with pelvic and/or acetabular trauma. However, the extent of their use will depend on local utilities (e.g., availability of CT scanners) and on the patient's clinical condition. Regarding the inaccuracy of conventional radiography in the diagnosis of injuries of the dorsal pelvic ring and of the acetabulum, computed tomography represents the most important imaging modality in the clinically stable patient. CT provides an exact staging of the extent of trauma and allows for differentiation of pelvic instabilities. CT clearly demonstrates the severity of acetabular trauma and is superior in the detection of local complicating factors, i.e., impressions fractures and (sub-)luxations of the femoral head as well as free intraarticular fragments. CT findings provide the basis for definite treatment regimens of the injured patient. By extension of the examination, all relevant organs and systems (craniospinal, cardiovascular, gastrointestinal, respiratory, genitourinary) can be imaged during one session. The speed of spiral CT scanners and their diagnostic accuracy will play a major role in the management of, especially, polytraumatized patients. The indication for angiography with the option of therapeutic embolization exists if a pelvic bleeding persists even after reposition and operative fixation of the injury. (orig.)

    Full Text Available Abstract Background Thoracic trauma is one of the leading causes of morbidity and mortality in developing countries. In this study, we present our 11-year experience in the management and clinical outcome of 888 chest trauma cases as a result of blunt and penetrating injuries in our university hospital in Damascus, Syria. Methods We reviewed files of 888 consequent cases of chest trauma between January 2000 and January 2011. The mean age of our patients was 31 ± 17 years mostly males with blunt injuries. Patients were evaluated and compared according to age, gender, etiology of trauma, thoracic and extra-thoracic injuries, complications, and mortality. Results The leading cause of the trauma was violence (41% followed by traffic accidents (33%. Pneumothorax (51%, Hemothorax (38%, rib fractures (34%, and lung contusion (15% were the most common types of injury. Associated injuries were documented in 36% of patients (extremities 19%, abdomen 13%, head 8%. A minority of the patients required thoracotomy (5.7%, and tube thoracostomy (56% was sufficient to manage the majority of cases. Mean hospital LOS was 4.5 ± 4.6 days. The overall mortoality rate was 1.8%, and morbidity (n = 78, 8.7%. Conclusions New traffic laws (including seat belt enforcement reduced incidence and severity of chest trauma in Syria. Violence was the most common cause of chest trauma rather than road traffic accidents in this series, this necessitates epidemiologic or multi-institutional studies to know to which degree violence contributes to chest trauma in Syria. The number of fractured ribs can be used as simple indicator of the severity of trauma. And we believe that significant neurotrauma, traffic accidents, hemodynamic status and GCS upon arrival, ICU admission, ventilator use, and complication of therapy are predictors of dismal prognosis.

  7. Blunt Chest Trauma in Mice after Cigarette Smoke-Exposure: Effects of Mechanical Ventilation with 100% O2.

    Directory of Open Access Journals (Sweden)

    Katja Wagner

    Full Text Available Cigarette smoking (CS aggravates post-traumatic acute lung injury and increases ventilator-induced lung injury due to more severe tissue inflammation and apoptosis. Hyper-inflammation after chest trauma is due to the physical damage, the drop in alveolar PO2, and the consecutive hypoxemia and tissue hypoxia. Therefore, we tested the hypotheses that 1 CS exposure prior to blunt chest trauma causes more severe post-traumatic inflammation and thereby aggravates lung injury, and that 2 hyperoxia may attenuate this effect. Immediately after blast wave-induced blunt chest trauma, mice (n=32 with or without 3-4 weeks of CS exposure underwent 4 hours of pressure-controlled, thoraco-pulmonary compliance-titrated, lung-protective mechanical ventilation with air or 100% O2. Hemodynamics, lung mechanics, gas exchange, and acid-base status were measured together with blood and tissue cytokine and chemokine concentrations, heme oxygenase-1 (HO-1, activated caspase-3, and hypoxia-inducible factor 1-α (HIF-1α expression, nuclear factor-κB (NF-κB activation, nitrotyrosine formation, purinergic receptor 2X4 (P2XR4 and 2X7 (P2XR7 expression, and histological scoring. CS exposure prior to chest trauma lead to higher pulmonary compliance and lower PaO2 and Horovitz-index, associated with increased tissue IL-18 and blood MCP-1 concentrations, a 2-4-fold higher inflammatory cell infiltration, and more pronounced alveolar membrane thickening. This effect coincided with increased activated caspase-3, nitrotyrosine, P2XR4, and P2XR7 expression, NF-κB activation, and reduced HIF-1α expression. Hyperoxia did not further affect lung mechanics, gas exchange, pulmonary and systemic cytokine and chemokine concentrations, or histological scoring, except for some patchy alveolar edema in CS exposed mice. However, hyperoxia attenuated tissue HIF-1α, nitrotyrosine, P2XR7, and P2XR4 expression, while it increased HO-1 formation in CS exposed mice. Overall, CS exposure

    A 57-year-old man came to our hospital by ambulance for a chest injury by a rifle gunshot. He had a penetrating injury of the chest wall, hemopneumothorax and pulmonary laceration. He was managed with chest drainage, oxygen inhalation. His respiratory and cardiac status was stable. However, for the purpose to prevent the development of empyema or pneumonia, and to check the existence of damage of intrathoracic structures by the gunshot injury, thoracoscopy was performed next day. He discharged without postoperative complications 17 days after the injury. Open thoracotomy is reported to be required in only about 10-15% of patients with chest injuries. However, operative indication of the chest injuries may spread in the future with the spread of thoracoscopy and its low invasiveness. PMID:16235855

  9. Computerized tomography of chest in emphysema and interstitial diseases diagnosis

    International Nuclear Information System (INIS)

    To study the effect of increasing the spatial resolution on thin section (1.5 mm) computed tomography (CT) of the chest, we compared images reconstructed with the standard algorithm (SA) to three other images obtained with 1) a high spatial frequency algorithm, 2) retrospective targeting to a small field of view (FOV) reconstructed with the high spatial frequency algorithm, and 3) the same high spatial frequency algorithm with images acquired with the small (0.6 mm) rather the large (0.9 mm) focal spot. Examinations were performed on a phantom, on normal subjects, and on patients with emphysema and other diffuse lung diseases. Modulation transfer function (MTF) calculations revealed that higher resolution was achieved on the small focal spot and high spatial frequency algorithm than on the standard algorithm. Evaluation of the four images from 25 normal subjects, 16 patients with emphysema and 9 with interstitial disease was performed by means of an ROC study. Results from the areas under the ROC curves, sensitivity and specificity have shown that images reconstructed with the high spatial frequency algorithm were preferred. We conclude that the use of a high spatial frequency algorithm increases spatial resolution and improves visibility of lung parenchyma. Although more evaluation is needed, the potential of increasing spatial resolution further by using a smaller focal spot is currently limited by the mas Available per slice and the associated increased level of quantum noise.

  10. CT diagnosis of intraperitoneal bladder rupture with blunt abdominal trauma

    International Nuclear Information System (INIS)

    Objective: To evaluate CT examination in the diagnosis of intraperitoneal bladder rupture (IPBR) caused by blunt abdominal trauma. Methods: All CT and clinical data of 9 patients with IPBR were reviewed retrospectively. Results: IPBR was detected on CT scans in all 9 patients. CT findings of IPBR included low -attenuation free intraperitoneal fluid collections in the lateral paravesical fossae, the pericolic space, the culde-sac of the pelvis, Morison's pouch, the peri-hepatic space, the perisplenic space and interspace of bowel loops in 9 cases with a lower CT density compared with pure blood. The disruption of the bladder wall was located by CT scan in 5 cases: high-attenuation bladder wall with focal defect in 3 cases and a tear drop-like deformity of the bladder in 2 cases. Other CT findings supporting the diagnosis of IPBR included an underfilled bladder in 8 cases, bladder contusion in 4 cases, and blood clots within the bladder in 6 cases. Conclusion: The presence of intraperitoneal fluid with a CT density less than that of pure blood strongly suggests extravasated urine in the trauma. Intraperitoneal and extraperitoneal rupture can be distinguished based on location of extravasated urine seen on CT scans. The precise localization of the ruptured bladder wall may be demonstrated by CT scan, which is valuable for surgical treatment

    Accurate radiographic diagnosis is a cornerstone of the clinical management and outcome prediction of the head-injured patient. New technological advances, such as multi-detector computed tomography (MDCT) scanning and diffusion-weighted magnetic resonance imaging (MRI) have influenced imaging strategy. In this article we review the impact of these developments on the neuroradiological diagnosis of acute head injury. In the acute phase, multi-detector CT has supplanted plain X-ray films of the skull as the initial imaging study of choice. MRI, including fluid-attenuated inversion recovery, gradient echo T2* and diffusion-weighted sequences, is useful in determining the severity of acute brain tissue injury and may help to predict outcome. The role of MRI in showing diffuse axonal injuries is emphasized. We review the different patterns of primary and secondary extra-axial and intra-axial traumatic brain lesions and integrate new insights. Assessment of intracranial hypertension and cerebral herniation are of major clinical importance in patient management. We discuss the issue of pediatric brain trauma and stress the importance of MRI in non-accidental injury. In summary, new developments in imaging technology have advanced our understanding of the pathophysiology of brain trauma and contribute to improving the survival of patients with craniocerebral injuries.

    2007-02-01

    Full Text Available Abstract Background Elastofibromas are benign soft tissue tumours mostly of the infrascapular region between the thoracic wall, the serratus anterior and the latissimus dorsi muscle with a prevalence of up to 24% in the elderly. The pathogenesis of the lesion is still unclear, but repetitive microtrauma by friction between the scapula and the thoracic wall may cause the reactive hyperproliferation of fibroelastic tissue. Methods We present a series of seven cases with elastofibroma dorsi with reference to clinical findings, further clinical course and functional results after resection, as well as recurrence. Data were obtained retrospectively by clinical examination, phone calls to the patients' general practitioners and charts review. Follow-up time ranged from four months to nine years and averaged 53 months. Results The patients presented with swelling of the infrascapular region or snapping scapula. In three cases, the lesion was painful. The ratio men/women was 2/5 with a mean age of 64 years. The tumor sizes ranged from 3 to 13 cm. The typical macroscopic aspect was characterized as poorly defined fibroelastic soft tissue lesion with a white and yellow cut surface caused by intermingled remnants of fatty tissue. Microscopically, the lesions consisted of broad collagenous strands and densely packed enlarged and fragmented elastic fibres with mostly round shapes. In all patients but one, postoperative seroma (which had to be punctuated occurred after resection; however, at follow-up time, no patient reported any decrease of function or sensation at the shoulder or the arm of the operated side. None of the patients experienced a relapse. Conclusion In differential diagnosis of soft tissue tumors located at this specific site, elastofibroma should be considered as likely diagnosis. Due to its benign behaviour, the tumor should be resected only in symptomatic patients.

  15. Chest X-ray quality in the diagnosis of pneumonia in children: from prescription to optimization

    International Nuclear Information System (INIS)

    Acute lower respiratory tract infection (ALRI), primarily pneumonia, is the leading cause of childhood death in developing countries. The increasing incidence of antimicrobial resistance and the high cost of vaccines lead to considering the first strategy to reduce pneumonia deaths the early detection of the disease. Case management begins with the clinical examination and may continue with the prescription of a chest x-ray. Consequently, the radiograph should meet quality standards, and radiologists and paediatricians must know how to interpret the images. Special attention should be paid on patient dose due to children radiosensitivity, high frequency and chest x rays rejection rate. This paper is a retrospective study of chest radiographs performed in 5731 children with clinical diagnosis of ALRI assisted in three Uruguayan hospitals during the three year investigation supported by the Division of Vaccines and Immunization of the Pan American Health Organization (PAHO) that had the aim of estimating the burden of pneumonia (from 2001 to 2004). It is analyzed the prescription of radiographs during the diagnosis and in later controls (2220 children assisted in two of the three hospitals). Patient doses are estimated from technical parameters and equipment specifications. The investigation also analyzes patient doses that could have been avoided if paediatricians had managed the disease according to the established protocols. Results show that 82.4 % of chest X-rays diagnosed pneumonia and that some children underwent up to ten radiographs. Significant differences were found in patient dose in the three hospitals, concluding that education on image quality on chest radiographs of radiologists, paediatricians and radiological technologists is the first and best tool for the earlier diagnosis of pneumonia in children and for the application of Radiation Protection (RP) principles in medical exposures.

    2012-08-01

    Full Text Available Abstract Introduction Crush asphyxia is different from positional asphyxia, as respiratory compromise in the latter is caused by splinting of the chest and/or diaphragm, thus preventing normal chest expansion. There are only a few cases or small case series of crush asphyxia in the literature, reporting usually poor outcomes. Case presentation We present the case of a 44-year-old Caucasian man who developed traumatic asphyxia with severe thoracic injury and mild brain edema after being crushed under heavy auto vehicle mechanical parts. He remained unconscious for an unknown time. The treatment included oropharyngeal intubation and mechanical ventilation, bilateral chest tube thoracostomies, treatment of brain edema and other supportive measures. Our patient’s outcome was good. Traumatic asphyxia is generally under-reported and most authors apply supportive measures, while the final outcome seems to be dependent on the length of time of the chest compression and on the associated injuries. Conclusion Treatment for traumatic asphyxia is mainly supportive with special attention to the re-establishment of adequate oxygenation and perfusion; treatment of the concomitant injuries might also affect the final outcome.

    Background Severe blunt chest trauma is associated with high mortality. Sepsis represents a serious risk factor for mortality in acute respiratory distress syndrome (ARDS). In septic patients with ARDS complement activation products were found to be elevated in the plasma. In single models like LPS or trauma complement has been studied to some degree, however in clinically highly relevant double hit models such as the one used here little data is available. Here, we hypothesized that absence of C5 is correlated with a decreased inflammatory response in trauma induced septic acute lung injury. Methods 12 hrs after DH in mice the local and systemic cytokines and chemokines were quantified by multiplex bead array or ELISA, activated caspase-3 by western blot. Data were analyzed using one-way ANOVA followed by post-hoc Sidak’s multiple comparison test (significance, p≤ 0.05). Results In lung tissue interleukin (IL)-6, monocyte chemo attractant protein-1 (MCP-1) and granulocyte-colony stimulating factor (G-CSF) was elevated in both C5-/- mice and wildtype littermates (wt), whereas caspase-3 was reduced in lungs after DH in C5-/- mice. Systemically, reduced keratinocyte-derived chemokine (KC) levels were observed after DH in C5-/- compared to wt mice. Locally, lung myeloperoxidase (MPO), protein, IL-6, MCP-1 and G-CSF in brochoalveolar lavage fluid (BALF) were elevated after DH in C5-/- compared to wt. Conclusions In the complex but clinically relevant DH model the local and systemic inflammatory immune response features both, C5-dependent and C5-independent characteristics. Activation of caspase-3 in lung tissue after DH was C5-dependent whereas local inflammation in lung tissue was C5-independent. PMID:27437704

  4. Cause analysis of missing diagnosis for vertebral fracture on lateral chest radiography

    International Nuclear Information System (INIS)

    Objective: To analyze the cause of missing diagnosis for vertebral fracture on lateral chest radiography. Methods: Lateral chest radiographies of 1638 hospitalized patients (871 males and 767 females) were retrospectively reviewed for identifying vertebral fractures. Their ages ranged from 50 to 91 years with the mean of 63.5 years. Complains and application for chest radiography in all patients were not related to osteoporosis and vertebral fracture. Vertebral fracture and fracture severity were evaluated using Genant's semiquantitative visual method, taking approximately a 20%-25% vertebral height reduction as mild grade, 26%--40% as moderate grade and 41% or greater as severe grade. Evaluation results of the vertebral fracture, original X-ray reports, as well as medical records were compared for further analysis. Results: Eighty-four in 1638 patients showed vertebral fractures on the lateral chest radiographies. Of them, vertebral fractures were reported in 30 cases and 54 patients were not reported on their original X-ray reports. There were 63 vertebral fractures in 54 un-reported patients, most of which were single fracture (75% or 47/63). Grade I fracture accounted for 54% (34/63), Grade II fracture 33% (21/63), while 13% presented grade III fracture (8/63). In all 84 patients with vertebral fractures, only 5 cases (6%) underwent dual energy X-ray absorptiometry (DXA) measurement, 5 cases (6%) were recorded to have vertebral fractures on the medical papers, as well as 15 cases (18%) were prescribed drugs related to the osteoporosis when discharged from hospital. All drugs prescribed for the 15 patients were limited only to calcium. Conclusions: More attention should be paid to osteoporosis by doctors including radiologists. Vertebral fracture on lateral chest radiography should be completely diagnosed, which is helpful for both prevention and treatment. (authors)

    Penetrating atherosclerotic ulcers (PAU) represent a pathological phenomenon in which ulceration of atheromatous lesions of the aorta penetrates the internal elastic lamina, reaching the middle muscular layer. These ulcers are more common in the descending thoracic aorta, being rare in the ascending aorta. The differential diagnosis between PAU and other entities of acute aortic syndromes (AAS) becomes difficult. The diagnosis of this disease is made through imaging studies: multidetector computed tomography (MDCT), magnetic resonance (MR) or transesophageal echocardiography (TEE). After diagnosis, the PAU of the ascending aorta should be treated surgically in an emergency context. In this paper the authors report a case of PAU in the aortic arch in a 84 years old patient admitted to the emergency room for chest pain. In this context a review of the natural evolution of this entity is made, with emphasis on diagnostic imaging modalities used for its characterization as well as their treatment options.

    Full Text Available Horner‘s syndrome is the triad of miosis, ptosis, and anhidrosis, resulting from disruption of the sympathetic pathways. This article describes an uncommon case of Horner‘s syndrome in a 22-year-old man after blunt trauma to the neck and chest without carotid artery dissection. The patient was brought to the emergency service after motorcycle fall. Neurologic examination revealed a patient presenting the score 15 at Glasgow Coma Scale. The left eyelid was 1-2 mm lower than the right. Carotid Doppler and angiotomography were undertaken and revealed no abnormalities of the carotid artery. CT disclosed a mediastinal hematoma extending to the left apex, compressing the left sympathetic chain. The understanding of this clinical entity may help the surgeon to make a better differential diagnosis in trauma patients in whom prompt diagnosis is critical to stablish the correct treatment.A síndrome de Horner compreende a tríade de miose, ptose e anidrose, resultado de lesão em algum ponto das vias simpáticas.

    2002-11-01

    The aim of the study was retrospectively to evaluate the spectrum of chest diseases in patients presenting with clinical suspicion of thoracic aortic dissection in the emergency department. We performed a retrospective medical records review of 86 men and 44 women (ages ranging between 23 and 106 years) with clinically suspected aortic dissection, for CT scan findings and final clinical diagnoses dating between January 1996 and September 2001. All images were obtained by using a standard protocol for aortic dissection. We found aortic dissection in 32 patients (24.6%), 22 of which were Stanford classification type A and 10 Stanford type B. In 70 patients (53.9%), chest pain could not be explained by the CT scan findings. However, in 28 patients (21.5%), CT scanning did reveal an alternate diagnosis that, along with the clinical impression, probably explained the patients' presenting symptoms, including: hiatal hernia (7), pneumonia (5), intrathoracic mass (4), pericardial effusion/hemopericardium (3), esophageal mass/rupture (2), aortic aneurysm without dissection (2), pulmonary embolism (2), pleural effusion (1), aortic rupture (1), and pancreatitis (1). In cases where there is clinical suspicion of aortic dissection, CT scan findings of an alternate diagnosis for the presenting symptoms are only slightly less common than the finding of aortic dissection itself. Although the spectrum of findings will vary depending upon your patient population, beware the alternate diagnosis. PMID:15290550

    The case history is described of a young man who presented with an apparent splenic rupture following thoracic compression during a rugby tackle. The actual diagnosis was that of an extra-pleural haematoma following transection of the internal mammary artery. This case is discussed within the context of the rarity of such a presentation--both in the site of the haematoma and the cause of the transection; and the problems posed in making the initial diagnosis.

    Highlights: • (Lateral) chest X-ray's are often performed in older individuals for various reasons. • Vertebral fractures are visualized on lateral chest X-ray, but the diagnosis of vertebral fractures is until now only validated on (lateral) spine X-ray's. • This study shows that a (lateral) chest X-ray is sufficient for the diagnosis of vertebral fractures. • Older individuals with a vertebral fracture on a (lateral) chest X-ray do not need further radiography with thoracic spine X-ray or vertebral fracture assessment with DXA. - Abstract: Background: In clinical practice lateral images of the chest are performed for various reasons. As these lateral chest X rays show the vertebrae of the thoracic and thoraco-lumbar region, we wondered if these X-rays can be used for evaluation of vertebral fractures instead of separate thoracic spine X-rays. Methods: To evaluate the agreement and intraobserver reliability of the semi-quantitative method for vertebral fractures on the lateral chest X-ray (X-chest) in comparison to the lateral thoracic spine X-ray (X-Tspine), two observers scored vertebral fractures on X-Tspine and twice on X-chest, separately, blinded and in different time periods. Agreement and Cohens’ kappa were calculated for a diagnosis of any fracture on patient level and on vertebral body level. The study was done in patients visiting an outpatient geriatric day clinic, with a high prevalence of vertebral fractures. Results: 109 patients were included. The intraobserver agreement for X-chest versus X-Tspine was 95–98% for the two levels of fracturing, with a Cohen's kappa of 0.88–0.91. The intraobserver agreement and reliability of the re-test on the X-chest showed an agreement between 91 and 98% with a Cohen's kappa of 0.81–0.93. More vertebrae were visible on the X-chest, mean 10.2, SD 0.66 versus mean 9.8, SD 0.73 on the X-Tspine (p < 0.001). Conclusion: The results show good agreement and intraobserver reliability on

  12. Roles of B-ultrasonography, CT examination in diagnosis and treatment of blunt renal trauma

    International Nuclear Information System (INIS)

    From March 1993 to June 1996, 53 patients with Blunt renal trauma were admitted to authors' hospital. B-ultrasonography was performed in 22 patients and CT in 31 patients, and their accurate diagnosis rates were 77.2% and 100% respectively. Among 41 patients with type I or II trauma, 3(73%) underwent operation, 1(2.4%) was treated by nephrectomy. Among 12 patients with type III or IV trauma, 11(91.7%) underwent operation and 9 were treated by nephrectomy. In authors' opinions, B-Ultrasonography can be applied in screening in early stage, and observing renal trauma repeatedly. CT examination can show the site and degree of renal trauma directly and can be applied in the diagnosis of the function of renal. Checking-up the injured renal should be avoid as best the authors can during operation. The renal should be preserved without injuring the main vessels

  13. Renal trauma imaging: Diagnosis and management. A pictorial review

    International Nuclear Information System (INIS)

    The purpose of this review is to illustrate and discuss the spectrum of imaging findings, particularly computed tomography (CT), of blunt and penetrating renal trauma, based on our own materials, according to the American Association for Surgery of Trauma (AAST) renal injury grading scale. The article also indicates the conditions in which interventional radiology procedures can be applied for the management of renal trauma. Cases for this pictorial review were selected from the imaging material collected at the Radiology Department of Hamad Medical Corporation during a 14-year period from 1999 to 2012. The material includes 176 cases (164 males and 12 females) with confirmed blunt or penetrating renal trauma. Following abdominal trauma, all patients had a CT examination performed on admission to the hospital and/or during hospitalization. The most representative and illustrative cases of renal trauma were reviewed according to CT findings and were categorized according to the AAST grading system. The review describes a spectrum of imaging presentations with special emphasis on the 5 grades of renal injury on a CT according to the AAST scale. The most representative cases were illustrated and discussed with indications of possible interventional radiology treatment. Two groups of patients not included in the AAST grading system were presented separately: those with preexisting renal abnormalities and those with sustained iatrogenic renal injury. Proper application of renal trauma grading scale is essential for selecting the patients for conservative treatment, surgery or interventional radiology procedure

  14. A combination of methylprednisolone and quercetin is effective for the treatment of cardiac contusion following blunt chest trauma in rats

    International Nuclear Information System (INIS)

    Cardiac contusion is a potentially fatal complication of blunt chest trauma. The effects of a combination of quercetin and methylprednisolone against trauma-induced cardiac contusion were studied. Thirty-five female Sprague-Dawley rats were divided into five groups (n=7) as follows: sham, cardiac contusion with no therapy, treated with methylprednisolone (30 mg/kg on the first day, and 3 mg/kg on the following days), treated with quercetin (50 mg·kg−1·day−1), and treated with a combination of methylprednisolone and quercetin. Serum troponin I (Tn-I) and tumor necrosis factor-alpha (TNF-α) levels and cardiac histopathological findings were evaluated. Tn-I and TNF-α levels were elevated after contusion (P=0.001 and P=0.001). Seven days later, Tn-I and TNF-α levels decreased in the rats treated with methylprednisolone, quercetin, and the combination of methylprednisolone and quercetin compared to the rats without therapy, but a statistical significance was found only with the combination therapy (P=0.001 and P=0.011, respectively). Histopathological degeneration and necrosis scores were statistically lower in the methylprednisolone and quercetin combination group compared to the group treated only with methylprednisolone (P=0.017 and P=0.007, respectively). However, only degeneration scores were lower in the combination therapy group compared to the group treated only with quercetin (P=0.017). Inducible nitric oxide synthase positivity scores were decreased in all treatment groups compared to the untreated groups (P=0.097, P=0.026, and P=0.004, respectively). We conclude that a combination of quercetin and methylprednisolone can be used for the specific treatment of cardiac contusion

    Magnetocardiography(MCG) has been proposed as a novel and non-invasive diagnostic tool for the detection of cardiac electrical abnormality associated with myocardial ischemia. In our previous study, we have proposed a new classification method of MCG parameters, based on the different populations of the parameters between coronary artery disease(CAD) patients, symptomatic patients and healthy volunteers. We used four parameters, representing the directional changes of the electrical activity in the period of an R-ST-T interval. In patients with chest pain and without ST-segment elevation, who were selected consecutively from all patients admitted to the hospital in 2004, the patients with CAD could be classified with a higher sensitivity than conventional methods, showing that the proposed method can be useful for the diagnosis of CAD with MCG. In this study, we examined the validity of the algorithm with the prior probability distribution in diagnosis of new patients admitted to the hospital in 2005. In the results, presence of CAD could be found with sensitivity and specificity of 81.3% and 71.4%, respectively, in patients with chest pain and non-diagnostic ECG findings.

    Multislice CT scanner advanced remarkably at the speed at which the chest CT images were acquired for mass screening. Mass screening based on multislice CT images requires a considerable number of images to be read. It is this time-consuming step that makes the use of helical CT for mass screening impractical at present. To overcome this problem, we have provided diagnostic assistance methods to medical screening specialists by developing a lung cancer screening algorithm that automatically detects suspected lung cancers in helical CT images and a coronary artery calcification screening algorithm that automatically detects suspected coronary artery calcification. Moreover, we have provided diagnostic assistance methods to medical screening specialists by using a lung cancer screening algorithm built into mobile helical CT scanner for the lung cancer mass screening done in the region without the hospital. We also have developed electronic medical recording system and prototype internet system for the community health in two or more regions by using the Virtual Private Network router and Biometric fingerprint authentication system and Biometric face authentication system for safety of medical information. Based on these diagnostic assistance methods, we have now developed a new computer-aided workstation and database that can display suspected lesions three-dimensionally in a short time. This paper describes basic studies that have been conducted to evaluate this new system.

    Objective: To investigate CT findings of concealed rupture of intestine following abdominal trauma. Methods: CT findings of 11 cases with concealed rupture of intestine following abdominal trauma proved by surgery were identified retrospectively. Results: The main special signs included: (1) Free air in 4 cases, mainly around injured small bowel or under the diaphragm, or in the retroperitoneal space or and in the lump. (2) High density hematoma between the intestines or in the bowel wall (4 cases). (3) Bowel wall injury sign, demonstrated as low density of the injured intestinal wall, attenuated locally but relatively enhanced in neighbor wall on enhanced CT. (4) Lump around the injured bowel wall with obvious ring-shaped enhancement (4 cases). Other signs included: (1) Free fluid in the abdominal cavity or between the intestines with blurred borders. (2) Bowel obstruction. Conclusion: CT is valuable in diagnosing concealed rupture of intestine following abdominal trauma. (authors)

  19. Cranium-brain trauma in computed tomographs - diagnosis and clinical correlation

    International Nuclear Information System (INIS)

    For the successful treatment of intracranial complications in the case of cranium-brain trauma a quick and exact diagnosis is necessary. The goal of this work was to test and evaluate the effectivity of computed tomography for neurotraumatology. Using 565 patients, who were acutely or at one time suffering from a cranium-brain trauma, the high validity of computed tomography for these injuries was proven. The following areas in question were studied with respect to the value of computed tomography in comparison to them: angiography, X-ray diagnostic, echoencephalography, brain scintigraphy, electroencephalography and neurological-psychopathological findings from cranium-brain trauma. Statement possibilities and difficulties of computed tomography are discussed in the cases of the following neurotraumatological diseases: extracranial hematomas; acute cranium-brain traumas; traumatic arachnoidal bleeding; diffuse brain edema; transtentorial herniation and brain contusions. At the end the diagnostic and therapeutic procedures in the case of cranium-brain trauma are presented. (orig.)

  20. Studies on computer-aided diagnosis systems for chest radiographs and mammograms (in Japanese)

    International Nuclear Information System (INIS)

    This thesis describes computer-aided diagnosis (CAD) systems for chest radiographs and mammograms. Preprocessing and imaging processing methods for each CAD system include dynamic range compression and region segmentation technique. A new pattern recognition technique combines genetic algorithms with template matching methods to detect lung nodules. A genetic algorithm was employed to select the optimal shape of simulated nodular shadows to be compared with real lesions on digitized chest images. Detection performance was evaluated using 332 chest radiographs from the database of the Japanese Society of Radiological Technology. Our average true-positive rate was 72.8% with an average of 11 false-positive findings per image. A new detection method using high resolution digital images with 0.05 mm sampling is also proposed for the mammogram CAD system to detect very small microcalcifications. An automated classification method uses feature extraction based on fractal dimension analysis of masses. Using over 200 cases to evaluate the detection of mammographic masses and calcifications, the detection rate of masses and microcalcifications were 87% and 96% with 1.5 and 1.8 false-positive findings, respectively. The classification performance on benign vs malignant lesions, the Az values that were defined by the areas under the ROC curves derived from classification schemes of masses and microcalcifications were 0.84 and 0.89. To demonstrate the practicality of these CAD systems in a computer-network environment, we propose to use the mammogram CAD system via the Internet and WWW. A common gateway interface and server-client approach for the CAD system via the Internet will permit display of the CAD results on ordinary computers

  1. Comparative Effectiveness of Emergency Resuscitative Thoracotomy versus Closed Chest Compressions among Patients with Critical Blunt Trauma: A Nationwide Cohort Study in Japan.

    Full Text Available Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency department or in the operating room was associated with favourable outcomes after blunt trauma and to compare its effectiveness with that of closed-chest compressions.This was a retrospective nationwide cohort study. Data were obtained from the Japan Trauma Data Bank for the period between 2004 and 2012. The primary and secondary outcomes were patient survival rates 24 h and 28 d after emergency department arrival. Statistical analyses were performed using multivariable generalized mixed-effects regression analysis. We adjusted for the effects of different hospitals by introducing random intercepts in regression analysis to account for the differential quality of emergency resuscitative thoracotomy at hospitals where patients in cardiac arrest were treated. Sensitivity analyses were performed using propensity score matching.In total, 1,377 consecutive, critical blunt trauma patients who received cardiopulmonary resuscitation in the emergency department or operating room were included in the study. Of these patients, 484 (35.1% underwent emergency resuscitative thoracotomy and 893 (64.9% received closed-chest compressions. Compared to closed-chest compressions, emergency resuscitative thoracotomy was associated with lower survival rate 24 h after emergency department arrival (4.5% vs. 17.5%, respectively, P < 0.001 and 28 d after arrival (1.2% vs. 6.0%, respectively, P < 0.001. Multivariable generalized mixed-effects regression analysis with and without a propensity score-matched dataset revealed that the odds ratio for an unfavorable survival rate after 24 h was lower for

    Ultrasound is of prO)len accuracy in abdominal and thoracic trauma and may be useful to diagnose extremity injury in situations where radiography is not available such as military and space applications. We prospectively evaluated the utility of extremity , ultrasound performed by trained, non-physician personnel in patients with extremity trauma, to simulate remote aerospace or military applications . Methods: Patients with extremity trauma were identified by history, physical examination, and radiographic studies. Ultrasound examination was performed bilaterally by nonphysician personnel with a portable ultrasound device using a 10-5 MHz linear probe, Images were video-recorded for later analysis against radiography by Fisher's exact test. The average time of examination was 4 minutes. Ultrasound accurately diagnosed extremity, injury in 94% of patients with no false positive exams; accuracy was greater in mid-shaft locations and least in the metacarpa/metatarsals. Soft tissue/tendon injury was readily visualized . Extremity ultrasound can be performed quickly and accurately by nonphysician personnel with excellent accuracy. Blinded verification of the utility of ultrasound in patients with extremity injury should be done to determine if Extremity and Respiratory evaluation should be added to the FAST examination (the FASTER exam) and verify the technique in remote locations such as military and aerospace applications.

    AIM: To retrospectively evaluate the preoperative diagnostic approaches and management of colonic injuries following blunt abdominal trauma.METHODS: A total of 82 patients with colonic injuries caused by blunt trauma between January 1992 and December 2005 were enrolled. Data were collected on clinical presentation, investigations, diagnostic methods,associated injuries, and operative management. Colonic injury-related mortality and abdominal complications were analyzed.RESULTS: Colonic injuries were caused mainly by motor vehicle accidents. Of the 82 patients, 58 (70.3%) had other associated injuries. Laparotomy was performed within 6 h after injury in 69 cases (84.1%), laparoscopy in 3 because of haemodynamic instability. The most commonly injured site was located in the transverse colon. The mean colon injury scale score was 2.8. The degree of faecal contamination was classified as mild in 18 (22.0%), moderate in 42 (51.2%), severe in 14 (17.1%), and unknown in 8 (9.8%) cases. Sixty-seven patients (81.7%) were treated with primary repair or resection and anastomosis. Faecal stream diversion was performed in 15 cases (18.3%). The overall mortality rate was 6.1%. The incidence of colonic injuryrelated abdominal complications was 20.7%. The only independent predictor of complications was the degree of peritoneal faecal contamination (P = 0.02).CONCLUSION: Colonic injuries following blunt trauma are especially important because of the severity and complexity of associated injuries. A thorough physical examination and a combination of tests can be used to evaluate the indications for laparotomy. One stage management at the time of initial exploration is most often used for colonic injuries.

  6. CT diagnosis of unsuspected pneumothorax after blunt abdominal trauma

    International Nuclear Information System (INIS)

    Review of abdominal CT scans for evaluation of blunt abdominal trauma yielded 35 cases of pneumothorax, 10 of which had not been diagnosed before CT by clinical examination of plain radiographs. Of the 10 cases initially diagnosed on CT, seven required tube thoracostomy for treatment of the pneumothorax. CT detection of pneumothorax is especially important if mechanical assisted ventilation or general anesthesia is used. Demonstration of pneumothorax requires viewing CT scans of the upper abdomen (lower thorax) at lung windows in addition to the usual soft-tissue windows

    The aim of this study was to review the diagnosis and operative management of cases of high-grade pancreatic trauma. A retrospective analysis was performed on 14 patients treated for high-grade pancreatic trauma at our institution between December 2008 and November 2013. The patients were treated for injuries resulting from blunt abdominal trauma. The main clinical data of the patients was analyzed, including time to diagnosis, initial serum amylase level, ultrasonography and abdominal computed tomography (CT) findings, pancreatic injury severity as scored according to the American Association for the Surgery of Trauma Organ Injury Scale, injury to other organs, operative treatment method, postoperative complications, and patient outcome. All 14 patients were diagnosed with severe (≥ grade III) pancreatic trauma. Diagnosis was confirmed in all seven hemodynamically stable patients that underwent CT and in 9/13 patients receiving ultrasound examination. All patients underwent surgical operations, including emergency pancreaticoduodenectomy (n = 8), splenectomy with distal pancreatectomy (n = 3), spleen-preserving distal pancreatectomy (n = 1), medial pancreatectomy with Roux-en-Y pancreaticojejunostomy (n = 1), and peripancreatic debridement and drainage (n = 1). Diagnosis was delayed beyond 24 h in two patients, both of whom underwent reoperative peripancreatic debridement and drainage, with one death. The complications included pancreatic fistula (n = 8), peripancreatic abscess (n = 2), hepatic artery hemorrhage (n = 1), gastrointestinal bleeding (n = 1), and intra-abdominal abscess (n = 1). CT is the most reliable method for diagnosing high-grade pancreatic trauma. Aggressive surgical therapy including pancreaticoduodenectomy is acceptable in hemodynamically stable patients.

    Full Text Available The aim of the study is to assess if copeptin, in combination with negative troponin, is able to accelerate the rule-out of AMI in patients with chest pain. The study was retrospectively conducted on three groups of patients selected according to their discharge diagnoses: patients with non-ST elevation myocardial infarction (NSTEMI, non-cardiac chest pain (NCCP, unstable angina (UA. Comparing the levels of copeptin, we found that the diagnosis of AMI is associated more often with copeptin positive values (> 14 pmol/l than the diagnosis of NCCP and UA. However, about a quarter of our patients in which the combination of copeptin and troponin in the first blood sample was negative, the final diagnosis was AMI. According to our results, the combination of the two negative markers does not allow a safe rule out of AMI at time zero.

  10. Combined determination of CEA, Fer, NSE and SCC levels in serum and chest effusion fluid for diagnosis of pulmonary cancer

    International Nuclear Information System (INIS)

    Objective: To study the clinical value of combined determination of CEA, Fer, NSE and SCC levels in serum and chest effusion fluid for dignosis of lung cancer. Methods: These four tumor markers were determined in serum and chest effusion fluid with RIA (NSE and SCC) or chemiluminescence method (CEA and Fer) in 52 patients with lung cancer, 48 patients with benign lung disease and 51 controls. Results: The serum and chest effusion fluid levels of CEA, Fer, NSE and SCC in patients with lung cancer were significantly higher than those in patients with benign lung diseases (all P<0.01) and 51 controls (P<0.001, <0.001, <0. 01 and <0.01 respectively). The positive rate of combined determination of CEA, Fer, NSE and SCC for lung cancer could be above 92.7%. Conclusion: Combined determination of CEA, Fer, NSE and SCC were a useful method for lung cancer diagnosis. (authors)

  11. Diagnosis of tumor and inflammation in the chest by positron emission tomography

    International Nuclear Information System (INIS)

    Positron emission tomography (PET) utilizing =fluorine-18=-fluorodeoxyglucose (FDG) has been shown to be highly accurate in differentiating benign from malignant pulmonary tumors. Our hospital started the PET clinics very recently. The FDG-PET for lung tumor diagnosis has been included in the menu of services from the beginning of this clinics. Our objective in this paper is to determine how effectively the FDG-PET reveals the nature of the tumor in the chest in relation to CT, tansthoracic fine-needle biopsy, and thoracotomy. Sixteen patients with lung lesions who had undergone PET were selected retrospectively as eligible for pathological justification. All the 14 cases of lung cancer showed highly positive uptake of FDG relative to the normal lung tissue. One case of benign tumor, one case of scarred aterectasis showed negative uptake. One case of active form of tuberculosis showed high uptake. Five lymph node stations in 3 cases were revealed to be the metastasized lymph nodes pathologically. FDG-PET visualized all of them. Absence of lymph node metastasis was confirmed in 7 cases. FDG-PET gave them negative results. (author)

  13. Modern CT diagnosis of acute thoracic and abdominal trauma

    International Nuclear Information System (INIS)

    Purpose. To evaluate a modified algorithm in the diagnostic management of polytraumatized patients by using whole body multislice CT (MSCT) as primary diagnostic tool.Material and methods. Between June 1999 and October 2000 532 polytraumatized patients were referred to the emergency department. 336 polytraumatized patients were primarily evaluated using whole body MSCT according to the ''Innsbruck Emergency Algorithm''. MSCT is performed immediately after cardiovascular stabilization of the patient. During the initial stabilization period free intraabdominal fluid is excluded or demonstrated by abdominal ultrasound. Time-consuming conventional radiographs are omitted with exception of an optional chest X-ray. In patients with suspected or obvious arterial injuries or fractures the multislice-CT-dataset is used to perform 2D and 3D reconstructions in order to optimize visualization of additional skeletal and vascular injuries.Results. By means of whole body MSCT it was possible to detect all injuries. The diagnostic advantage of whole body MSCT as compared to conventional X-ray was analyzed in 111 consecutive polytraumatized patients with an injury severity score (ISS) of 34.77. The early use of MSCT shortened the time for diagnostic work-up substantially (approximately 50%).Conclusion. Whole body multislice-CT used as primary diagnostic tool in the management of polytraumatized patients allows for a fast, accurate and comprehensive diagnostic work-up. (orig.)

  15. Diagnosis of abdominal abscesses in patients with major trauma: the use of computed tomography

    International Nuclear Information System (INIS)

    The usefulness of computed tomography (CT) in diagnosing abdominal abscesses was evaluated prospectively in 69 septic patients who had suffered massive trauma. For the 82 abdominal CT scans obtained, the accuracy rate was 84%, the sensitivity was 92%, and the specificity was 79%. With the use of abdominal CT, 32 patients were spared a ''blind'' laparotomy in the search for the focus of infection. It is concluded that CT is of significant value in the diagnosis of abdominal abscess in the septic trauma patient

  16. CT diagnosis in the evaluation of vertebral trauma

    International Nuclear Information System (INIS)

    The diagnostic capability of the CT scan of the vertebral trauma and a comparison with the results of a routine roentgenogram and tomogram were studied in 11 patients. In total, there were 15 fractured vertebrae: 3 in the upper cervical, 3 in the lower cervical, and 9 in the thoracic and thoraco-lumbar vertebrae. In the detailed evaluation of the vertebral fractures, CT provided more information than plain films in all 15 fractured vertebrae, with a better visualization of the spinal bony details, particularly at the upper cervical, thoracic, and thoraco-lumbar levels, where the interpretation of the spinal abnormalities is usually difficult because of adjacent structures such as the skull and thorax. Only CT was able to demonstrate impingements on the vertebral canal by bony fragments. Post-traumatic syringomyelia was incidentally demonstrated in one patient on a plain CT. In 6 patients, conventional tomography was done, but no additional information with regard to spinal instability and spinal-cord compression was obtained. The usage of sagittal tomography was also limited, because it required a change in the patient's position, which might worsen the neurological deficits. On the other hand, a plain roentgenogram and conventional tomography were superior in the evaluation of spinal malalignment and fractures running horizontally. In summary, both plain roentgenograms and CT images provided detailed information about vertebral injury, whereas conventional tomography is judged to be inferior and not always necessary. Based on these results, our new diagnostic and therapeutic approaches using CT for the vertebral injuries were presented. (author)

    Computer-aided quantitative analysis of chest radiographs is a useful tool in describing alterations in lung shape that occur in patients with emphysema. In the present study, the analysis was limited to the lateral chest radiograph, but we expect that the use of the postero-anterior view may further improve the rate of correct classification.

  18. Pneumothorax in severe thoracic traumas

    International Nuclear Information System (INIS)

    The authors reviewed CT scans and supine chest X-ray of 47 patients affected by severe thoracic trauma, examined in 1985-86. The sensibility of the two methodologies in the assessment of pneumothorax was compared. CT detected 25 pneumothorax, whereas supine chest X-ray allowed a diagnosis in 18 cases only. In 8 of the latter (44.4%) the diagnosis was made possible by the presence of indirect signs of pneumothorax only - the most frequent being the deep sulcus sign. The characterization of pneumothorax is important especially in the patients who need to be treated with mechanical ventilation therapy, or who are to undergo surgery in total anaesthesia

    With the depiction of pulmonary arteries, coronary arteries, and the aorta, CT angiography of the chest offers a comprehensive diagnostic work-up of unclear chest pain. The aim of this study was to assess the diagnostic accuracy of dual-source CT in this patient group. A total of 47 patients suffering from unclear chest pain were examined with a Siemens Somatom Definition. Volume and flow of contrast media (Ultravist, Schering) were adapted to the body weight. The examinations were evaluated with regard to image quality and contrast opacification and to the diagnostic accuracy with reference to the final clinical diagnosis. Adequate contrast opacification was achieved in all examinations. The depiction of the coronary arteries was diagnostic in all cases. The cause of chest pain could be identified in 41 cases. Among the diagnoses were coronary and myocardial pathologies, valvular disease, aortic aneurysms and dissections, pulmonary embolism, and pneumonic consolidation. DSCT angiography of the chest offers a very good image quality even at high heart rates so that a high diagnostic accuracy is achieved in patients with acute chest pain. (orig.)

    The role of clinical information and chest film for the discrimination between invasive pulmonary aspergillosis (IPA) and its differential diagnoses in human immunodeficiency virus (HIV) infection was studied. The diagnostic performance of clinical information and chest film alone and in combination was studied for eight internists and eight radiologists with regular exposure to IPA patients. The multicenter case sample consisted of 25 patients with proven IPA and 25 with other pulmonary diseases typical for HIV. The cases were presented on a CD-ROM. Receiver operating characteristics (ROC) methodology was employed. With clinical information alone, internists achieved the highest diagnostic performance (area under curve/AUC=0.84). Viewing the chest films did not contribute to their performance (AUC=0.80, P=0.26). The radiologist's performance on the basis of viewing the chest film (AUC=0.75) increased significantly (P=0.012) when clinical information (AUC=0.83) was supplied. IPA cases with characteristic radiological appearance were correctly identified in 90% with chest film. For radiologists with regular exposure to HIV patients, chest films hold relevant information and contribute to the determination in cases with characteristic radiological appearance. Overall and especially in cases with less characteristic radiological appearance, they have significant profit from full access to the clinical data. For internists with regular exposure to HIV patients, chest films do not provide information essential for the verification or differentiation of potential IPA. (orig.)

    2015-10-01

    In 1985 Andreasen and Andreasen published a paper on the diagnosis of luxation injuries and outlined the importance of standardized clinical, radiographic, and photographic techniques. Now 30 years later, these recommendations remain current in the International Association of Dental Traumatology (IADT) guidelines for the management of dental trauma and describe circumstances surrounding the time of injury, the extent of trauma (e.g., type of luxation injury), healing potential (e.g., stage of root development) as well as information concerning subsequent treatment. The purpose of this review was to include findings for other types of trauma and to discuss more recent studies that augment and/or improve on the original findings from 30 years ago. The present review discusses the use of a standardized clinical registration (pulpal sensibility testing, laser Doppler flowmetry, mobility testing), radiographic survey, and photographic registration of the traumatized patient. Moreover, the value of digital radiographs and recent developments in computer tomography with respect to possible enhancement of the trauma diagnosis are discussed. PMID:26058528

  6. A study on computer-aided diagnosis based on temporal subtraction of sequential chest radiographs (in Japanese)

    International Nuclear Information System (INIS)

    An automated digital image subtraction technique for use with pairs of temporally sequential chest radiographs has been developed to aid radiologists in the detection of interval changes. Automated image registration based on nonlinear geometric warping is performed prior to subtraction in order to deal with complicated radiographic misregistration. Processing includes global matching, to achieve rough registration between the entire lung fields in the two images, and local matching, based on a cross-correlation method, to determine local shift values for a number of small regions. A proper warping of x,y-coordinates is determined by fitting two-dimensional polynomials to the distributions of the shift values. One image is warped and then subtracted from the other. The resultant subtraction images were able to enhance the conspicuity of various types of interval changes. Improved global matching based on a weighted template matching method achieved robust registration even with photofluorographs taken in chest mass screening programs, which had previously presented us with a relatively large number of poor-registration images. The new method was applied to 129 pairs of chest mass screening images, and offered registration accuracy as good as manual global matching. An observer test using 114 cases including 57 lung cancer cases presented better sensitivity and specificity on average compared to conventional comparison readings. In addition, newly developed image processing that eliminates the rib edge artifacts in subtraction images was applied to 26 images having pathological interval changes; results showed the potential for application to automated schemes for the detection of interval change patterns. With its capacity to improve the diagnostic accuracy of chest radiographs, the chest temporal subtraction technique promises to become an important element of computer-aided diagnosis (CAD) systems

  7. Bone scanning a useful addition in the diagnosis of ankle joint trauma

    International Nuclear Information System (INIS)

    A retrospective study of the indication in 169 scintigraphic examinations of the ankle joint was made. Usually joints respond to trauma with a generalized increase of the concentration of the radiopharmaceutical. By using a highly performed technique the focal hot spot caused by the fracture can be seen in the bone scan. The focal accumulation of the radioactive material must not correspond to a bone fracture in any case. The ligamentous avulsion of a bone chip and/or the periosteum can yield the same image but it cannot be diagnosed by radiographic techniques. Initially the routine radiograph and even the tomograph often are interpreted as normal or equivocal. In these cases of ankle trauma bone scanning completes the clinical evaluation. Although bone scanning is very important in the diagnosis of any traumatic lesion of the ankle joints it cannot replace the conventional X-ray technique. (orig.)

    Blunt thoraco-abdominal trauma in collision injuries in road traffic accident (RTA) occasionally results in diaphragmatic injury and rupture besides other serious multisystem injuries. These diaphragmatic injuries (DI) frequently go undetected specially when occur on the right side. DI associated with hemothorax need insertion of intercostal tube drainage (ICTD). ICTD has never been reported to precipitate diaphragmatic rupture and hernia. We are reporting such a rare case for the first time in medical literature. PMID:26933316

    Imaging of the pediatric chest continues to evolve rapidly. All chapters in this 2nd edition of Pediatric Chest Imaging have been extensively updated, with additional disease-specific information and numerous new illustrations. The book thus presents the state of the art in the diagnosis of pediatric chest disorders, highlighting the role played by advanced technology. As the conventional features of most of these disorders are extremely well known, special attention is devoted to the technical aspects of the modern imaging modalities, their indications, and the diagnostic information that they supply. Individual chapters focus on chest ultrasound, nuclear medicine imaging, high-resolution chest CT, helical CT, and pediatric cardiac CT and pediatric cardiacMRI. Others are directed towards specific disorders, including congenital malformations of the chest, chest tumors, pulmonary infection, trauma, the lung in systemic diseases, the pediatric airway, foreign bodies, the thymus, and the chest wall. Without exception, the authors of this book are internationally known specialists with great expertise in the field. This book will serve as a handy, superbly illustrated reference for all who routinely image children, as well as for those who need access to information on how best to image them. (orig.)

    The purpose of this work is twofold: (i) to develop a CAD system for the assessment of emphysema by digital chest radiography and (ii) to test it against CT imaging. The system is based on the analysis of the shape of lung silhouette as imaged in standard chest examination. Postero-anterior and lateral views are processed to extract the contours of the lung fields automatically. Subsequently, the shape of lung silhouettes is described by polyline approximation and the computed feature-set processed by a neural network to estimate the probability of emphysema. Images of radiographic studies from 225 patients were collected and properly annotated to build an experimental dataset named EMPH. Each patient had undergone a standard two-views chest radiography and CT for diagnostic purposes. In addition, the images (247) from JSRT dataset were used to evaluate lung segmentation in postero-anterior view. System performances were assessed by: (i) analyzing the quality of the automatic segmentation of the lung silhouette against manual tracing and (ii) measuring the capabilities of emphysema recognition. As to step i, on JSRT dataset, we obtained overlap percentage (Ω) 92.7±3.3%, Dice Similarity Coefficient (DSC) 95.5±3.7% and average contour distance (ACD) 1.73±0.87 mm. On EMPH dataset we had Ω=93.1±2.9%, DSC=96.1±3.5% and ACD=1.62±0.92 mm, for the postero-anterior view, while we had Ω=94.5±4.6%, DSC=91.0±6.3% and ACD=2.22±0.86 mm, for the lateral view. As to step ii, accuracy of emphysema recognition was 95.4%, with sensitivity and specificity 94.5% and 96.1% respectively. According to experimental results our system allows reliable and inexpensive recognition of emphysema on digital chest radiography. PMID:22522287

  12. Technetium-99m-Sestamibi in the diagnosis of acute chest pain

    International Nuclear Information System (INIS)

    Full text: A 45-year-old male was admitted to coronary care with a two-day history of recurrent chest pain. Despite maximal medical therapy, pain persisted. Examination and ECG with pain, were normal, suspicion of ischaemia was moderately high but coronary angiography was not immediately available. Technetium-99m-Sestamibi was prepared at the start of the day according to the standard preparation protocol (Du Pont). Coronary Care informed the Nuclear Medicine Department immediately the patient experienced a further episode of chest pain. Technetium-99m-Sestamibi was administered in coronary care, 4.30 minutes after being advised of the onset of further chest pain. Images were acquired 60 minute post-injection; 15 minutes after the patient had been given 200 mL of milk. A triple-headed gamma camera was used to acquire SPECT images over a 1200 arc, 30 frames of 30 seconds using a 64 x 64 matrix. The patient was laying prone with arms raised out of the field of view. Images showed a normal distribution of technetium-99m -Sestamibi throughout the myocardium. Due to ongoing clinical suspicion by the treating physician, coronary angiography was subsequently performed. This showed normal coronary arteries. Medical therapy was ceased and the patient discharged the next day. We concluded that the chest pain at the time of injection was not ischaemic. Previous trials had shown a 95% sensitivity for this method of diagnosing ischaemia. This method permits a novel and simple technique for diagnosing myocardial ischaemia and obviating the need for cardiac catheterization in this group of patients

    Full Text Available World Health Organization (WHO radiological classification remains an important entry criterion in epidemiological studies of pneumonia in children. We report inter-observer variability in the interpretation of 169 chest radiographs in children suspected of having pneumonia.An 18-month prospective aetiological study of pneumonia was undertaken in Northern England. Chest radiographs were performed on eligible children aged ≤16 years with clinical features of pneumonia. The initial radiology report was compared with a subsequent assessment by a consultant cardiothoracic radiologist. Chest radiographic changes were categorised according to the WHO classification.There was significant disagreement (22% between the first and second reports (kappa = 0.70, P<0.001, notably in those aged <5 years (26%, kappa = 0.66, P<0.001. The most frequent sources of disagreement were the reporting of patchy and perihilar changes.This substantial inter-observer variability highlights the need for experts from different countries to create a consensus to review the radiological definition of pneumonia in children.

    A traumatic infra-renal aortic dissection is a rare but life-threatening injury that follows deceleration injuries. The mechanism of blunt abdominal aortic injury involves both direct and indirect forces. The successful management of patients with traumatic injuries depends on a prompt suspicion of the injury and early diagnosis and therapy. Missed injuries in trauma patients are well-described phenomena and implementation of the ATLS® trauma schedule led to a decrease in the number of missed...

    Introduction. Inguinal hernias are very common in men. A clinical exam can do the diagnosis easily. But bowel perforation inside an inguinal hernia caused by a directly blunt trauma is rare and can have important consequences. Up to now, there have been a few case reports that described blunt injury to the inguinal area causing traumatic perforation of the bowel in the inguinal hernia. Case Report. We present a case of a 45-year-old Eastern European man with a small perforation of ileal bowels and a peritonitis after direct blunt trauma to the inguinal hernia region, with no inguinal hernia known by the patient, and show how the diagnosis can be difficult. Conclusion. This case shows that external forces, that may seem too trivial to cause intraperitoneal injury, can cause significant injury when applied to a patient with a hernia and shows how a careful examination, with the help of an abdominal CT scan, is important even if the patient do not seem to have an inguinal hernia.

    International Nuclear Information System (INIS)

    Traumatic lesions of the skeleton are common occurrences in everyday living and at all ages. The presence of a fracture upon clinical examination may or may not be obvious, thus leaving the radiological investigation as a focal point for definitive diagnosis. With today's sophisticated imaging system which render a minimal dosage of radiation to the patient, whenever there is any doubt concerning the presence of a fracture, radiographs should be performed. There may be severe medicolegal ramifications when fractures have been overlooked due to the lack of appropriate radiographs being taken or the oversight of the observer. When a fracture or dislocation is identified, key features must be evaluated. Successful treatment of fractures starts with accurate diagnosis, which requires a well-performed and accurately interpreted radiographic examination. The minimum examination is considered to be two radiographs at 90 degrees to each other; anything less is considered an incomplete examination. The purpose of this chapter is to familiarize the reader with the most common types of fractures and dislocations. The chapter is presented in a regional manner, with a preliminary presentation of descriptive terminology, definitions, and a review of fracture repair

    Digital chest tomosynthesis (DCT) is a 3D imaging modality which has been shown to approach the diagnostic capability of CT, but uses only one-tenth the radiation dose of CT. One limitation of current commercial DCT is the mechanical motion of the x-ray source which prolongs image acquisition time and introduces motion blurring in images. By using a carbon nanotube (CNT) x-ray source array, we have developed a stationary digital chest tomosynthesis (s- DCT) system which can acquire tomosynthesis images without mechanical motion, thus enhancing the image quality. The low dose and high quality 3D image makes the s-DCT system a viable imaging tool for monitoring cystic fibrosis (CF) patients. The low dose is especially important in pediatric patients who are both more radiosensitive and have a longer lifespan for radiation symptoms to develop. The purpose of this research is to evaluate the feasibility of using s-DCT as a faster, lower dose means for diagnosis and monitoring of CF in pediatric patients. We have created an imaging phantom by injecting a gelatinous mucus substitute into porcine lungs and imaging the lungs from within an anthropomorphic hollow chest phantom in order to mimic the human conditions of a CF patient in the laboratory setting. We have found that our s-DCT images show evidence of mucus plugging in the lungs and provide a clear picture of the airways in the lung, allowing for the possibility of using s- DCT to supplement or replace CT as the imaging modality for CF patients.

  19. Contribution of chest x-ray to the diagnosis of HIV virus infection

    International Nuclear Information System (INIS)

    After revising literature concerning Pneumocystis Carinii Pneumoniae (PCP), the authors undertook a close examination of the immunological system of the HIVab-positive patients that suffered opportunistic pneumopathy from PCP. Hundred-forty-three cases of HIVab-positive (mean age of 29), prevalently heroine drugusers, were studied. There were 13 AIDS, 26 ARC, 91 LAS cases and 13 patients with only Ab positivity for HIV. Four hundred chest radiographs were examined without previous knowledge of case histories. A small number of hilum and/or mediastinal lymphoadenopathies was observed. Moreover, percentage increase in acute lung inflammatory diseases, mainly interstitial, was seen. These data were correlated to the worsening of the HIV infection and to the developing of LAS, ARC and ADIS. In a number of cases there was radiological evidence of pregressed inflammatory episodes. The clinical pattern of PCP patients is dramatic and often fatal. Clinical-radiological cases with special reference to acute interstitial disease, caused by opportunistic agents, are presented

  20. Criteria for applying imaging diagnosis and initial management for pediatric head trauma

    International Nuclear Information System (INIS)

    It may be difficult to perform CT for pediatric head trauma because of body movement and radiation exposure. Imaging application criteria were established, in which patients diagnosed as less likely to have an intracranial lesion meeting the criteria were not indicated for imaging and subjected to course observation at home, and this policy was explained to the parents. When consent was obtained, patients were followed up at home, and we checked on the condition by making a phone call 4-8 hours after injury. The patients were 103 infants aged 15 years or younger brought to the emergency medical care center of our hospital between May and August 2008. Imaging was basically indicated for cases of traffic accidents, falls from a high level, those brought in by ambulance, referred cases, and cases with disturbance of consciousness, neurologically abnormal findings, vomiting on examination, and trauma requiring X-ray examination in addition to that for the head. However, apart from these cases, imaging was not required. Imaging was not necessary for 94% of infant cases. The parents were convinced by the explanation and selected course observation at home in 94% of cases for which imaging was judged as unnecessary. None of the patients required re-examination based on the conditions reported in phone calls to homes. Imaging diagnosis for pediatric head trauma is not always necessary, and its application should be decided on after consultation. When no imaging is performed, this should be fully explained at the initial treatment before selecting course observation at home. Checking on the child's condition by making a phone call several hours after injury is useful for both patients and physicians. (author)

  1. CT scanning in pediatric head trauma: correlation of clinical features with CT scan diagnosis

    International Nuclear Information System (INIS)

    A retrospective review was conducted on 205 cases of pediatric head trauma for which cranial computed tomography scans were done at the Makati Medical Center, to determine which clinical features might positively predict an abnormality on CT scan. The clinical findings of loss of consciousness, GCS < 12, vomiting headache, seizures, and focal abnormalities on Neurologic Examination were significantly associated with abnormal findings on CT scan. However, a significant discrepancy does exist as to how accurately clinical findings do in fact predict normal and abnormal CT scan findings. Such a discrepancy allows us to conclude that a more liberal use of CT Scanning in cases of pediatric head trauma must be stressed to insure proper diagnosis. This study shows that when a patient presents with the aforementioned positive signs and symptoms, or with a focal neurologic deficit, or in combination, a 60-100 % positive prediction of abnormal CT Scan can be made. However, prediction of normal CT Scan is only 0-40%. (Author)

  2. Isolated Blunt Duodenal Trauma: Delayed Diagnosis and Favorable Outcome with "Quadruple Tube" Decompression

    Full Text Available Context Isolated blunt duodenal injury is a rare finding associated with high morbidity and significant mortality. The early identification of a duodenal injury is usually difficult, considering the anatomical location of the duodenum and lack of peritoneal signs and diagnostic delay is part of the clinical picture in most cases. Case report A 43-year-old man was admitted to our hospital after a motor vehicle collision. At admission he underwent emergency surgery because of lower extremities fractures. Twelve hours later he started to complain an increasing abdominal pain; blood tests showed serum amylase up to 180 U/L and a CT scan demonstrated a perforation of the third duodenal portion. At laparotomy a Grade III injury of the duodenum was evident. The laceration was sutured and a “quadruple-tube” decompression was performed. The postoperative course was uneventful. One year after surgery he is well without any long-term complication. Conclusion A high degree of suspicion is necessary for early diagnosis of blunt duodenal trauma and CT scan should be performed in case of all significant epigastric trauma. In most cases primary direct repair of duodenal wounds can be safely achieved and duodenal decompression via triple or quadriple tube technique is required to decrease the risk of duodenal fistula.

  3. Value of the computerized axial tomography for early diagnosis of cranio cerebral trauma

    International Nuclear Information System (INIS)

    A descriptive and cross-sectional study was conducted in 62 patients with cranio cerebral trauma admitted to 'Saturnino Lora' Provincial Teaching Hospital of Santiago de Cuba, from January 2005 to May 2006, in whom computerized axial tomography indicated at the emergency room was performed with the purpose of evaluating the effectiveness of this radiographic technique for early diagnosis of the injury. In the case material there was neither association between the source and imaging results, nor between the age and sex. The main clinical manifestations were vomiting, headache and motor deficit as well as frontal location, intraparenchymatous hematoma (the latter as the most common image finding) and the hyperdense area as tomographic pattern. The survival was of 91,9%

  4. Computer-aided diagnosis of pneumoconiosis abnormalities extracted from chest radiographs scanned with a CCD scanner

    International Nuclear Information System (INIS)

    This paper presents a computer-aided diagnosis for pneumoconiosis radiographs obtained with a common charge-coupled devices (CCD) scanner. Since the current computer-aided diagnosis systems of pneumoconiosis are not practical for medical doctors due to high costs of usage for a special scanner, we propose a novel system which measures abnormalities of pneumoconiosis from lung images obtained with a common CCD scanner. Experimental results of discriminations between normal and abnormal cases for 56 right-lung images including 6 standard pneumoconiosis images have shown that the proposed abnormalities are well extracted according to the standards of pneumoconiosis categories.

This study is designed to provide a new scoring system for a better diagno- sis of IAI after blunt trauma. Methods: This prospective observational study was performed from April 2011 to October 2012 on patients aged above 18 years and suspected with blunt abdominal trauma (BAT admitted to the emergency department (ED of Imam Hussein Hospital and Shohadaye Hafte Tir Hospital. All patients were assessed and treated based on Advanced Trauma Life Support and ED protocol. Diagnosis was done according to CT scan findings, which was considered as the gold standard. Data were gathered based on patient's history, physical exam, ultrasound and CT scan findings by a general practitioner who was not blind to this study. Chisquare test and logistic regression were done. Factors with significant relationship with CT scan were imported in multivariate regression models, where a coefficient (β was given based on the contribution of each of them. Scoring system was developed based on the obtained total βof each factor. Results: Altogether 261 patients (80.1% male were enrolled (48 cases of IAI. A 24-point blunt abdominal trauma scoring system (BATSS was developed. Patients were divided into three groups including low (score<8, moderate (8≤score<12 and high risk (score≥12. In high risk group immediate laparotomy should be done, moderate group needs further assessments, and low risk group should be kept under observation. Low risk patients did not show positive CT-scans (specificity 100%. Conversely, all high risk patients had positive CT-scan findings (sensitivity 100%. The receiver operating characteristic curve indicated a close relationship between the results of CT scan and BATSS (sensitivity=99.3%. Conclusion: The present scoring system furnishes a

  8. Radiological diagnosis in patients with head injury alone or in combination with multiple trauma

    International Nuclear Information System (INIS)

    Purpose. Head injury alone or in combination with multiple trauma is the main cause of death and severe disability in individuals under 45 years old. This review is intended to describe the relevant imaging modalities, to analyze their specific value and limitations and to illustrate the most important radiologic findings. The indications for diagnostic imaging within the context of an interdisciplinary linkage of diagnostic and therapeutic measures are discussed.Material and methods. Recent publications are analyzed and compared to the experiences of our own hospital. In terms of a critical synoptic assessment the currently best standard of care is described in consideration of an interdisciplinary care concept.Results. Radiologic imaging modalities crucially contribute to the complete injury assessment and provide an indispensable basis for any therapeutic decision. Comprehensive neuromonitoring and reliable demonstration of delayed or secondary brain damage is impossible without modern imaging technology. Computed tomography (CT) further continues to be the most important imaging modality, while magnetic resonance imaging despite it's partly superior diagnostic informations remains reserved to particular diagnostic problems.Conclusions. Suitable constructive prerequisites, an interdisciplinary care concept and integration of the radiologist in hospital-adapted diagnostic and therapeutic algorithms significantly improves the outcome of patients with acute head injury. Beside the correct diagnosis itself the time to establish a diagnosis above all has a crucial impact on successful management and good outcome of these patients. (orig.)

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A contusão miocárdica está freqüentemente associada ao trauma torácico fechado. Seu correto diagnóstico é um constante desafio aos profissionais que trabalham em unidades de emergência, devido aos seus sintomas inespecíficos e a ausência de exames subsidiários com precisão para fazer o diagnóstico. Dentre os diversos métodos diagnósticos estudados, tem-se destacado nos últimos anos o papel dos indicadores de necrose miocárdica troponina I e troponina T. Por serem proteí­nas constituintes do aparelho de regulação contrátil celular, são liberadas na corrente sanguínea somente após a perda da integridade de membrana dos miócitos e, portanto, são altamente específicas para detectar lesão miocárdica. CONTEUDO: Foi realizada uma revisão de estudos clínicos nas bases eletrônicas de dados MedLine e LILACS, no período de janeiro de 1980 a novembro de 2006, sobre a importância da dosagem seriada de troponina como instrumento diagnóstico e preditor de evolução clínica desfavorável nos pacientes com contusão miocárdica. CONCLUSÕES: Embora exista maior especificidade das troponinas I e T quando comparadas aos indicadores tradicionais, CKMB massa e CPK total, esses dois indicadores apresentarem sensibilidade e valor preditivo positivo baixos para diagnosticar contusão miocárdica. Pacientes que apresentam alterações eletrocardiográficas, elevação de troponinas, ou ambas, devem permanecer em observação em unidade de terapia intensiva (UTI, por no mínimo 24 horas, período em que se desenvolve a maioria das complicações decorrentes da contusão miocárdica.BACKGROUND AND OBJECTIVES: Myocardial contusion is often associated with blunt chest trauma.

    Mass screening based on multi-helical CT images requires a considerable number of images to be read. It is this time-consuming step that makes the use of helical CT for mass screening impractical at present. Moreover, the doctor who diagnoses a medical image is insufficient in Japan. To overcome these problems, we have provided diagnostic assistance methods to medical screening specialists by developing a lung cancer screening algorithm that automatically detects suspected lung cancers in helical CT images, a coronary artery calcification screening algorithm that automatically detects suspected coronary artery calcification and a vertebra body analysis algorithm for quantitative evaluation of osteoporosis likelihood by using helical CT scanner for the lung cancer mass screening. The functions to observe suspicious shadow in detail are provided in computer-aided diagnosis workstation with these screening algorithms. We also have developed the telemedicine network by using Web medical image conference system with the security improvement of images transmission, Biometric fingerprint authentication system and Biometric face authentication system. Biometric face authentication used on site of telemedicine makes "Encryption of file" and "Success in login" effective. As a result, patients' private information is protected. We can share the screen of Web medical image conference system from two or more web conference terminals at the same time. An opinion can be exchanged mutually by using a camera and a microphone that are connected with workstation. Based on these diagnostic assistance methods, we have developed a new computer-aided workstation and a new telemedicine network that can display suspected lesions three-dimensionally in a short time. The results of this study indicate that our radiological information system without film by using computer-aided diagnosis workstation and our telemedicine network system can increase diagnostic speed, diagnostic accuracy and

    Full Text Available A traumatic infra-renal aortic dissection is a rare but life-threatening injury that follows deceleration injuries. The mechanism of blunt abdominal aortic injury involves both direct and indirect forces. The successful management of patients with traumatic injuries depends on a prompt suspicion of the injury and early diagnosis and therapy. Missed injuries in trauma patients are well-described phenomena and implementation of the ATLS® trauma schedule led to a decrease in the number of missed injuries, but trauma computed tomography (CT scans in injured patients are still not standard. We report on a 54-year old Caucasian female patient who was involved in a car accident. The fellow passenger of the car was seriously injured. The patient had been previously treated at two different hospitals, and a dislocated acetabular fracture had been diagnosed. Because of this injury, the patient was transferred to our institution, a level 1 trauma-center where, according to the nature of the accident as a high-energy trauma, a complete polytrauma management was performed at the time of admission. During the body check, a moderate tension of the lower parts of the abdomen was detected. During the CT scan, an aneurysm of the infra-renal aorta with a dissection from the height of the second lumbar vertebral body to the iliac artery was observed. The patient required an operation on the day of admission. After 19 days post-trauma care the patient was able to leave our hospital in good general condition. Therefore, missed injuries in multiple injury patients could be fatal, and it is essential that the orthopedic surgeon leaves room for suspicion of injuries based on the nature of the trauma. Traumatic injuries of the abdominal aorta are rare. According to the ATLS® trauma schedule, all of the patients who have experienced high-energy trauma and associated fractures should undergo routine screening using a trauma CT scan with contrast agents to detect

    Full Text Available In this article, we present the case of a 57-yearold man with cervical and mediastinal tumor mass, normal blood count as well as virusological status. Cervical tumor tissue biopsy revealed cells positive for CD34, CD13, LCA, CD33, and CD163 but negative for T-cell and B-cell markers, NK-cell markers, plasmacytic markers and anaplastic large cell lymphoma markers. These features were consistent with myeloid sarcoma of the neck with involvement of the mediastinum. We discussed differential diagnosis and therapy of isolated myeloid sarcoma and suggest that clinical presentation, cell morphology, complete immunophenotype, and specific genotypic lesions in some cases, must be evaluated.

    A 58 year old man was admitted to the accident and emergency department following an industrial accident in which he sustained a three part fracture dislocation of his right humerus. Chest radiography revealed a large mass in the right upper hemithorax and, when the patient became hypotensive, an emergency thoracotomy was performed. The mass was found to be a massive intrathoracic lipoma. This case shows how preexisting intrathoracic lesions may be mistaken for subclavian or great vessel trauma following violent shoulder girdle injury. The differential diagnosis of traumatic and non-traumatic intrathoracic mass lesions in chest radiography should be considered carefully.

    d-dimers are cleavage products of fibrin that occur during plasmin-mediated fibrinolysis of blood clots. In the emergency department, d-dimer measurement represents a valuable and cost-effective tool in the differential diagnosis of acute chest pain including the main life-threatening entities: acute coronary syndrome, pulmonary embolism, and acute aortic syndrome. Whereas the diagnostic and prognostic values of d-dimer testing in acute coronary syndrome is of less priority, increases of d-dimers are frequently found in venous thromboembolism and acute aortic syndromes, especially acute aortic dissection. As to the high negative predictive value of d-dimer in those disorders, patients with low to intermediate pretest probability may profit in terms of less necessity of further non-invasive or even invasive imaging, simultaneously reducing potential complications and healthcare-related costs. However, because of the low specificity of the different d-dimer tests in contrast to its frequent usage, adequate interpretation is required. Age-related adjustment of d-dimer levels may be used to increase its diagnostic power. PMID:25392700

  16. Usefulness of gastroesophageal reflux scintigraphy using the knee-chest position for the diagnosis of gastroesophageal reflux disease

    International Nuclear Information System (INIS)

    The aim of this study is to evaluate the usefulness of gastroesophageal reflux (GER) scintigraphy using the knee-chest (KC) position for the diagnosis of gastroesophageal reflux disease (GERD). The study subjects were 37 patients with GERD and 8 healthy volunteers (control group). Endoscopically observed esophageal mucosal breaks were evaluated with the Los Angeles classification. For GER scintigraphy, the subjects ingested liquid yogurt labeled with 99mTc-diethylene triamine pentaacetic acid (99mTc-DTPA) and water. Imaging was performed in the supine and KC position, and GER was graded as 1-4 according to the extent of GER assessed by scintigraphy. GER scintigraphy revealed no reflux in the control group (specificity: 100%). In the supine position, gastroesophageal reflux was observed in 49% of the patients with GERD, compared to 76% in the KC position. 21 of 23 (91%) patients with erosive esophagitis were shown to have GER with scintigraphy. GER scintigraphy revealed severe reflux (grade 3 or 4) (83%, 10/12) in the patients who had severe mucosal breaks (the Los Angels classification grade C or D). GER scintigraphy detected grade 1 or 2 reflux in 7 of the 14 patients who were endoscopically negative. There was a correlation between the endoscopically determined severity of mucosa and the reflux grade which was determined with GER scintigraphy. GER scintigraphy can detect gastroesophageal reflux with a high sensitivity in the KC position and might be a useful method in the screening and assessment of the severity of this disease. This method would be useful for the diagnosis of GERD in endoscopically negative patients. (author)

    Full Text Available Abstract Background Blunt carotid and vertebral artery injury (BCVI occur infrequently. The incidence of this type of injury is difficult to determine as many emergency room patients are neurologically asymptomatic. The statistics have not been reported in Brazil. The objectives of the current study were: To evaluate the accuracy of criteria used to recommend angiotomography in the diagnosis of cervical BCVI in 100 patients with blunt cervical trauma in the trauma services section of a Brazilian quaternary care hospital. Methods During a 30-month (2006-2008, all patients admitted to the emergency room of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo with blunt cervical trauma and potential risk of cervical vessel injury, were subjected to cervical angiotomography to diagnose BCVI. The data analyzed are presented as mean ± standard deviation, and statistical analyses included Chi-square and Fisher's exact tests, and the Mann-Whitney test. Results During the study period 2467 blunt trauma patients were admitted. In 100 patients that met the criteria for inclusion in the study, angiotomography identified 23 with BCVI, including 17 males and six females. The mean patient age was 34.81 ± 14.84 years. Car crash (49% and car-pedestrian accidents (24% were the most frequent causes of injury. Ten patients had internal carotid artery injuries, two patients had common carotid artery injuries, and 11 patients had vertebral artery injuries. Seven patients presented with Degree I arterial injuries, 10 patients presented with Degree II artery injuries, four patients presented with Degree IV artery injuries, one patient presented with a Degree V artery injury, and one patient had a carotid fistula. Seven out of the 23 patients with BCVI (30.4% presented with cervical vertebrae fractures, and 11 out of the 23 patients with BCVI (47.8% presented with facial fractures (LeFort II and III.

  2. Improved detection of pulmonary nodules on energy-subtracted chest radiographs with a commercial computer-aided diagnosis software: comparison with human observers

    International Nuclear Information System (INIS)

    To retrospectively analyze the performance of a commercial computer-aided diagnosis (CAD) software in the detection of pulmonary nodules in original and energy-subtracted (ES) chest radiographs. Original and ES chest radiographs of 58 patients with 105 pulmonary nodules measuring 5-30 mm and images of 25 control subjects with no nodules were randomized. Five blinded readers evaluated firstly the original postero-anterior images alone and then together with the subtracted radiographs. In a second phase, original and ES images were analyzed by a commercial CAD program. CT was used as reference standard. CAD results were compared to the readers' findings. True-positive (TP) and false-positive (FP) findings with CAD on subtracted and non-subtracted images were compared. Depending on the reader's experience, CAD detected between 11 and 21 nodules missed by readers. Human observers found three to 16 lesions missed by the CAD software. CAD used with ES images produced significantly fewer FPs than with non-subtracted images: 1.75 and 2.14 FPs per image, respectively (p=0.029). The difference for the TP nodules was not significant (40 nodules on ES images and 34 lesions in non-subtracted radiographs, p = 0.142). CAD can improve lesion detection both on energy subtracted and non-subtracted chest images, especially for less experienced readers. The CAD program marked less FPs on energy-subtracted images than on original chest radiographs. (orig.)

  3. Accuracy of Lung Ultrasonography versus Chest Radiography for the Diagnosis of Adult Community-Acquired Pneumonia: Review of the Literature and Meta-Analysis.

    Xiong Ye

    Full Text Available Lung ultrasonography (LUS is being increasingly utilized in emergency and critical settings. We performed a systematic review of the current literature to compare the accuracy of LUS and chest radiography (CR for the diagnosis of adult community-acquired pneumonia (CAP. We searched in Pub Med, EMBASE dealing with both LUS and CR for diagnosis of adult CAP, and conducted a meta-analysis to evaluate the diagnostic accuracy of LUS in comparison with CR. The diagnostic standard that the index test compared was the hospital discharge diagnosis or the result of chest computed tomography scan as a "gold standard". We calculated pooled sensitivity and specificity using the Mantel-Haenszel method and pooled diagnostic odds ratio using the DerSimonian-Laird method. Five articles met our inclusion criteria and were included in the final analysis. Using hospital discharge diagnosis as reference, LUS had a pooled sensitivity of 0.95 (0.93-0.97 and a specificity of 0.90 (0.86 to 0.94, CR had a pooled sensitivity of 0.77 (0.73 to 0.80 and a specificity of 0.91 (0.87 to 0.94. LUS and CR compared with computed tomography scan in 138 patients in total, the Z statistic of the two summary receiver operating characteristic was 3.093 (P = 0.002, the areas under the curve for LUS and CR were 0.901 and 0.590, respectively. Our study indicates that LUS can help to diagnosis adult CAP by clinicians and the accuracy was better compared with CR using chest computed tomography scan as the gold standard.

  4. Significance of magnetic resonance imaging in the diagnosis of vertebral artery injury associated with blunt cervical spine trauma

    International Nuclear Information System (INIS)

    Vertebral artery injury associated with non-penetrating cervical trauma is rare. We report 11 cases of vertebral artery injury diagnosed with magnetic resonance imaging (MRI) after blunt trauma to the cervical spine and discuss about the importance of MRI in the diagnosis of this injury. Seven cases were caused by motor vehicle accidents, three by diving accidents, and one by static compression of the neck. All of the patients had documented cervical spine fractures and dislocations. In three patients, the diagnosis of complete occlusion of the vertebral artery was made on the basis of MRI and digital subtraction angiography (DSA). In the other patients, mural injuries of the vertebral artery were demonstrated with DSA. These 11 patients presented with acute, nonspecific changes in neurological status. Two had infarctions of the cerebellum and brainstem. None were treated with anticoagulants. All of them survived and were discharged to other hospitals for physical and occupational therapy. Although DSA remains the gold standard for diagnosing vertebral artery injuries, MRI is a newer modality for assessing cervical cord injury, and it may be useful for evaluating the presence of vertebral injury after blunt cervical spine trauma.

  5. Influence of 'optical illusion' on the detectability of pneumothorax in diagnosis for chest CT images. Substantiation by visual psychological simulation images

    International Nuclear Information System (INIS)

    Some cases have been reported in which an optical illusion of lightness perception influences the detectability in diagnosis of low-density hematoma in head CT images in addition to the visual impression of the photographic density of the brain. Therefore, in this study, the author attempted to compare the detectability in diagnosis for chest images with pneumothorax using visual subjective evaluation, and investigated the influence of optical illusion on that detectability in diagnosis. Results indicated that in the window setting of lung, on such an occasion when the low-absorption free space with pneumothorax forms a crescent or the reduced lung borders on the chest-wall, an optical illusion in which the visual impression on the difference of the film contrast between the lung and the low-absorption free space with pneumothorax was psychologically emphasized when contrast was observed. In all cases the detectability in diagnosis for original images with the white thorax and mediastinum was superior to virtual images. Further, in case of the virtual double window setting of lung, thorax, and mediastinum, under the influence of the difference in the radiological anatomy of thorax and mediastinum as a result of the grouping theories of lightness computation, an optical illusion different from the original images was observed.

  6. Radiation doses and image quality in pediatric chest X-ray for the diagnosis of pneumonia in selected Latin American countries

    International Nuclear Information System (INIS)

    Full text: Pneumonia and acute lower respiratory infections in general, is the leading cause of child death in developing countries. According to the World Health Organization (WHO), 4 millions of children die annually due to this disease. Despite the growing use of vaccination as an alternate approach to reduce mortality, the increasing antimicrobial resistance and the high costs of vaccines remain important obstacles in the global struggle against the disease. The usual treatment strategy begins with a clinical examination of the patient followed by the prescription of a chest X-ray. Radiography would appear as the best available method for diagnosing pneumonia only if radiologists (and other health professionals such as pediatricians) knew how to interpret the images showed in the radiographs, and these meeting the standards of quality (anatomic structures, image contrast and optical density, and patient dose among other factors). On the other hand, special attention should be paid on patient doses due to children's specific radiosensitivity, repeated and extended use of chest x-ray in all Radiology Departments, and high rejection rate due to both equipment malfunction and to human skills shortcomings. Patient doses of chest X-ray performed to children less than 5 years old in PAHO Sentinel Hospitals for surveillance of bacterial pneumonias in various Latin American countries were estimated using technical parameters and equipment specifications. Image quality was compared to WHO criteria for chest X-rays quality. Results showing differences in patient doses translates on one hand the impact of specific characteristics of the radiological equipment, including equipment limitations and performance of the radiographs and on the other various and divers levels of health professionals skills and training on image quality interpretation and dose optimization. The study concludes that professionals' training and education on chest radiographs image quality constitutes

  7. CT of the chest in suspected child abuse using submillisievert radiation dose

    International Nuclear Information System (INIS)

    The cornerstone of child abuse imaging is the skeletal survey, but initial imaging with radiographs may not demonstrate acute and non-displaced fractures, especially those involving the ribs. Given the high mortality of undiagnosed non-accidental trauma, timely diagnosis is crucial. CT is more sensitive in assessing rib fractures; however the effective radiation dose of a standard chest CT is high. We retrospectively identified four children (three boys, one girl; age range 1-4 months) admitted between January 2013 and February 2014 with high suspicion for non-accidental trauma from unexplained fractures of the long bones; these children all had CT of the chest when no rib fractures were evident on the skeletal survey. The absorbed radiation dose estimates for organs and tissue from the four-view chest radiographs and subsequent CT were determined using Monte Carlo photon transport software, and the effective dose was calculated using published tissue-weighting factors. In two children, CT showed multiple fractures of the ribs, scapula and vertebral body that were not evident on the initial skeletal survey. The average effective dose for a four-view chest radiograph across the four children was 0.29 mSv and the average effective dose for the chest CT was 0.56 mSv. Therefore the effective dose of a chest CT is on average less than twice that of a four-view chest radiograph. Our protocol thus shows that a reduced-dose chest CT may be useful in the evaluation of high specificity fractures of non-accidental trauma when the four-view chest radiographs are negative. (orig.)

  9. Traumatic pancreatic injury - an elusive diagnosis: experience from a developing country urban trauma referral centre

    International Nuclear Information System (INIS)

    Objective: To determine the frequency of pancreatic injury in patients presenting with trauma and to review the mechanism of injury, management, subsequent complications and in-hospital mortality rate associated with these patients. Methods: The retrospective study included all patients over 18 years of age presenting with pancreatic injury due to trauma at the Aga Khan University Hospital, Karachi, between January 1990 and December 2009. Patients with iatrogenic pancreatic injury were excluded. The severity of the injury was assessed using the Injury Severity Score, while it was graded according to the scale defined by the American Association for the Surgery of Trauma. SPSS 17 was used for statistical analysis. Results: A total of 30 patients were identified representing just 1.5% of the total adult abdominal trauma patients. The mean age of the patients was 28+-9.7 years. There were 28 (93.3%) males and just 2 (6.6%) females. The complication rate was 80% (n=24) and the mortality rate was 23.3% (n=7). Of the 30 patients, 19 (63%) had been transferred from some other medical facility. The mean length of hospital stay was 16.4+-20.6 days (range 5-97 days). Conclusion: Surgical management in pancreatic trauma patients should be dictated by the degree and location of pancreatic injury, associated injuries and time from event to presentation. Mortality was primarily determined by associated life-threatening injuries. (author)

  11. The imaging of paediatric thoracic trauma

    International Nuclear Information System (INIS)

    Major chest trauma in a child is associated with significant morbidity and mortality. It is most frequently encountered within the context of multisystem injury following high-energy trauma such as a motor vehicle accident. The anatomic-physiologic make-up of children is such that the pattern of ensuing injuries differs from that in their adult counterparts. Pulmonary contusion, pneumothorax, haemothorax and rib fractures are most commonly encountered. Although clinically more serious and potentially life threatening, tracheobronchial tear, aortic rupture and cardiac injuries are seldom observed. The most appropriate imaging algorithm is one tailored to the individual child and is guided by the nature of the traumatic event as well as clinical parameters. Chest radiography remains the first and most important imaging tool in paediatric chest trauma and should be supplemented with US and CT as indicated. Multidetector CT allows for the accurate diagnosis of most traumatic injuries, but should be only used in selected cases as its routine use in all paediatric patients would result in an unacceptably high radiation exposure to a large number of patients without proven clinical benefit. When CT is used, appropriate modifications should be incorporated so as to minimize the radiation dose to the patient whilst preserving diagnostic integrity. (orig.)

  12. Specificity and sensitivity of chest radiographs in the diagnosis of paediatric pulmonary tuberculosis and the value of additional high-kilovolt radiographs

    International Nuclear Information System (INIS)

    Tuberculosis (TB) remains the most common notifiable infectious disease in South Africa. The diagnosis of pulmonary TB in children is often very difficult because of the non-specific radiological signs and inter-observer variation in the interpretation of radiographs. The frontal high-kilovolt (kV) radiograph has been used to assess the effect of TB adenopathy on the tracheobronchial tree and to detect endobronchial lesions. The aims of the present study were to assess the specificity and sensitivity of chest radiographs in the diagnosis of pulmonary TB and to assess whether the addition of the high-kV radiograph affects these parameters. The study group consisted of paediatric patients suspected of having pulmonary TB over a 6-year period. These patients had clinical, bacteriological and radiographic examinations. Radiographs were examined by one experienced radiologist in two sittings separated by a 6-week interval. On the first sitting, only standard radiographs were examined and, on the second sitting, these were supplemented with high-kV radiographs. Differences in the detection of each recognized radiological feature of pulmonary TB before and after the addition of the high-kV film were analysed for statistical significance. The frequency of radiographic findings in our study compared favourably with other reports. No statistically significant differences for the detection of radiographic features consistent with pulmonary TB, or for the diagnosis of pulmonary TB, were demonstrated between the two sittings. Specificity increased from 74.4% to 86.6% with the addition of the high-kV view and sensitivity remained constant at 38.8%. The present study does not support the routine use of the frontal high-kV radiograph for the diagnosis of pulmonary TB. This paper also confirms the findings of others, that standard chest radiographs are a poor indicator of pulmonary TB in children Copyright (2004) Blackwell Publishing Asia Pty Ltd

    Four cases of thoracic lymphoma mimicking chest wall tumors are presented. As resection is not the treatment of first choice in lymphomas, pretherapeutical evaluation of chest wall tumors should include a thoroughly staging and a biopsy for histopathological diagnosis. Chest wall destruction due to an anterior mediastinal mass, or a chest wall tumor associated with mediastinal lymph node enlargement, could be suspicious of thoracic lymphoma. Lymphoma with chest wall involvement mostly turns o...

  14. Computer-aided diagnosis for the detection of the pulmonary nodules on digital chest radiography in lung cancer screening

    International Nuclear Information System (INIS)

    Objective: To evaluate the value of computer-aided detection (CAD) system for pulmonary nodule detection using digital chest radiography in lung cancer screening. Methods: One hundred consecutive digital chest radiographs from 6280 outpatients for lung cancer screening were independently reviewed by a thoracic radiologist and a computer-aided pulmonary nodule detection system. The radiographs were also reviewed by two experienced thoracic radiologists and the true nodules confirmed by two radiologists with reference to the CT images were marked and stored as a gold standard in the CAD system. The sensitivity and false positive of the radiologist and the CAD system for the detection of nodules on digital chest radiographs were compared. Results: Ninety-five and 304 nodules were identified by radiologist and the CAD system, respectively. Of 134 nodules marked as true nodules by experienced radiologists, 82 (61.2%) and 105 (78.4%) nodules were identified by the radiologist and the CAD, respectively. The radiologist missed 35 true nodules which were only detected by CAD. The CAD system missed 10 true nodules which were only detected by radiologist. One hundred and twelve (83.6%) nodules were identified by radiologist with the CAD system. One hundred and ninety-nine nodules identified by CAD were false-positive with a rate of 2.0 (199/100) per case. Conclusion: Combining review of digital radiographs by radiologist with CAD system can improve the detection of pulmonary nodules in lung cancer screening. (authors)

    Nuclear medicine imaging procedures can play a significant role in evaluating the pulmonary complications that are seen in trauma patients. A quantitative method for measuring increased pulmonary capillary permeability that uses Tc-99m HSA allows early diagnosis of acute respiratory distress syndrome (ARDS) and accurately differentiates this condition from pneumonia or cardiogenic pulmonary edema. This technique may be of great value in following the response to therapy. The use of 133Xe to diagnose inhalation injury remains an important diagnostic tool, particularly at hospitals with specialized burn units. Regional decreases in ventilation-perfusion images reliably localize aspirated foreign bodies. Radionuclide techniques that are used to demonstrate gastropulmonary aspiration remain controversial and require further clinical evaluation. Pulmonary perfusion imaging, although nonspecific, may provide the earliest clue for correct diagnosis of fat embolism, air embolism, contusion, or laceration. Furthermore, the possibility of perfusion abnormality due to these uncommon conditions must be remembered whenever trauma patients are evaluated for pulmonary thromboembolism with scintigraphy. Occasionally, liver or spleen scintigraphy may be the most appropriate procedure when penetrating chest trauma also involves these subdiaphragmatic organs. PMID:6226097

    Objective To investigate the diagnostic value of chest CT scan combined with telomerase activity and p16 gene methylation from exfoliated cells of sputum in 55 cases of solitary pulmonary nodules (SPN; ≤30 mm)suspected early peripheral lung cancer. Methods The sputum specimens from 34 cases of cancer nodules and 21 cases of benign lesion were detected for telomerase activity by TRAP-PCR-ELISA and p16 gene methylation by PCR-based methylation analysis. Results The qualitative diagnostic accuracy of CT scan was 61.8%(34/55) for SPN provided by pathology. Cytology analysis of sputum was positive in 13 cases (38.2%). Telomerase activity was positive in 29 cases: sensitivity was 79.4%, specificity was 90.5%, accuracy was 83.6%; p16 gene methylation was found in 11 cases: sensitivity was 32.4%, specificity was 100.0%, and accuracy was 58.2%. The sensitivity was increased to 86.1% by combination of telomerase activity and p16 gene methylation. Compared with nodules without malignant CT signs, expression of telomerase activity and p16 methylation of SPN with malignant CT signs (lobulation or spiculate protuberance or spicule sign) had a significant difference (P<0.01). Conclusion The results suggest that chest CT scan combined with telomerase activity and p16 gene methylation detection in sputum for patients with peripheral lung cancer may enhance the diagnostic value of radiology and conventional cytology.

  20. The accuracy of chest radiographs in the detection of congenital heart disease and in the diagnosis of specific congenital cardiac lesions

    International Nuclear Information System (INIS)

    Congenital heart disease (CHD) is a significant cause of morbidity and mortality in pediatric patients. Traditional teaching holds that specific types of CHD can be diagnosed on the chest radiograph (CXR) through pattern recognition. To determine the accuracy of radiologists in detecting CHD on the CXR. This study was a blinded retrospective review of chest radiographs from 281 patients (<12 years) by five pediatric radiologists from three institutions. Thirteen groups were evaluated that included 12 categories of CHD and a control group of patients without heart disease. Radiographs were assessed for heart size, heart and mediastinal shape and vascularity. Clinical information, angiography, echocardiograms and surgery were used as the gold standard for definitive diagnosis. The average accuracy of the five readers in distinguishing normal from CHD patients was 78% (range of 72% to 82%). The overall measure of accuracy in distinguishing specific congenital cardiac lesions among 13 groups of patients was 71% (range of 63% to 79%). CXR alone is not diagnostic of specific cardiac lesions, with a low accuracy of only 71%. We believe that less emphasis should be placed on the use of radiographs alone in diagnosing specific congenital cardiac lesions. (orig.)

  2. The chest

    International Nuclear Information System (INIS)

    Radiographic interpretation of chest films of newborns in respiratory distress remains one of the most difficult aspects of pediatric radiology. Complex pulmonary and cardiac adjustments to extrauterine life are rapidly taking place. The small, fluid-filled fetal lung must rid itself of fluid and fill with air. The high vascular resistance of the fetal pulmonary bed and the open ductus arteriosus allow shunting of blood in both directions. Films taken in this period of time may show lungs that resemble those seen in congestive heart failure or fluid overload. When these findings are observed in infants who may appear dusky or even cyanotic, the result may be the diagnosis of disease in normal infants passing through a stormy transition period. To make things worse, the films are taken as portable surpine films, usually in an isolette in the intensive care unit (ICU). The phase of respiration is difficult, if not impossible, to control, and lateral films are usually not obtained. Many of the infants are on assisted ventilation either by tube or nasal prongs-nasal continuous positive airway pressure (CPAP)-and lungs can appear over-inflated or whited out, depending on the pressures used and the phase of the respiratory cycle. Prolonged crying itself can make lungs appear semiopaque; the next breath may show such a dramatic reinflation that it is hard to believe the two films are of the same infant, made only seconds apart. Is the heart large? Or is it the thymus? Are the lungs ''wet''? Is there infection? Is there pulmonary vascular engorgement? Why are these films so hard to interpret? They have no easy answers. The radiologist must realize that the neonatal intensive care personnel, armed though they may be with blood gas values, are no better at interpreting films. If anything, they read into them what they wish to see

    The purpose of the study was to determine the diagnostic sensitivity and specificity of multidetector CT (MDCT) in detection of diaphragmatic injury following penetrating trauma. Chest and abdominal CT examinations performed preoperatively in 136 patients after penetrating trauma to the torso with injury trajectory in close proximity to the diaphragm were reviewed by radiologists unaware of surgical findings. Signs associated with diaphragmatic injuries in penetrating trauma were noted. These signs were correlated with surgical diagnoses, and their sensitivity and specificity in assisting the diagnosis were calculated. CT confirmed diaphragmatic injury in 41 of 47 injuries (sensitivity, 87.2%), and an intact diaphragm in 71 of 98 patients (specificity, 72.4%). The overall accuracy of MDCT was 77%. The most accurate sign helping the diagnosis was contiguous injury on either side of the diaphragm in single-entry penetrating trauma (sensitivity, 88%; specificity, 82%). Thus MDCT has high sensitivity and good specificity in detecting penetrating diaphragmatic injuries. (orig.)

    Variable chest wall disorders include hemorrhage, inflammation and a tumor on the chest wall. Especially in females, abnormal anterior chest wall findings can appear as breast lesions due to the anatomic relationship between the chest wall and the breast. Sonography is the first diagnostic tool to utilize for chest wall disorders and has an important role for the differential diagnosis. In this study, we introduce sonographic findings of the various chest wall disorders that are discovered incidentally during an examination for a palpable mass or pain in the breast. We also describe sonographic findings that additionally performed of sonography-guided core needle biopsy

    As an intensive care nurse with experience of caring for critically ill patients in the UK and on deployed operations overseas, I found the CPD article useful in reviewing the pathophysiology of a pneumothorax, use of intrapleural chest drains, observations that should be recorded, and nursing care and management of a patient with an intrapleural chest drain. Reflecting on the time out activities in the CPD article was valuable. PMID:25005418

  8. Abdominal trauma

    International Nuclear Information System (INIS)

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

    Hydrostatic pulmonary edema is as an abnormal increase in extravascular water secondary to elevated pressure in the pulmonary circulation, due to congestive heart failure or intravascular volume overload. Diagnosis of hydrostatic pulmonary edema is usually based on clinical signs associated to conventional radiography findings. Interpretation of radiologic signs of cardiogenic pulmonary edema are often questionable and subject. For a bedside prompt evaluation, lung ultrasound (LUS) may assess...

    Thoracic injury is currently the second leading cause of trauma-related death and rib fractures are the most common of these injuries. Flail chest, as defined by fracture of three or more ribs in two or more places, continues to be a clinically challenging problem. The underlying pulmonary contusion with subsequent inflammatory reaction and right-to-left shunting leading to hypoxia continues to result in high mortality for these patients. Surgical stabilization of the fractured ribs remains controversial. We review the history of management for flail chest alone and when combined with pulmonary contusion. Finally, we propose an algorithm for nonoperative and surgical management. PMID:24887787

    Duodenal trauma is uncommon but nowadays seen more and more frequently due to the increased automobile accidents and violent events. The management of duodenal trauma can be complicated, especially when massive injury to the pancreatic-duodenal-biliary complex occurs simultaneously. Even the patients receive surgeries in time, multiple postoperative complications and high mortality are common. To know and manage duodenal trauma better, we searched the recent related literature in PubMed by the keywords of duodenal trauma, therapy, diagnosis and abdomen. It shows that because the diagnosis and management are complicated and the mortality is high,duodenal trauma should be treated in time and tactfully.And application of new technology can help improve the management. In this review, we discussed the incidence,diagnosis, management, and complications as well as mortality of duodenal trauma.

  13. Reduction of false-positive shadows in computer. Aided diagnosis system for chest x-ray CT images

    International Nuclear Information System (INIS)

    In this paper, we report how we have improved our method for reducing the false-positive rate in computer-aided diagnosis in the Lung cancer Screening system by CT (LSCT). We had changed the target size for the detection of cancers from more than 10 mm to more than 5 mm in diameter. As a result of this change, many false positives with a diameter of less than 10 mm were observed. In order to reduce this false-positive rate, we propose a method involving feature analysis of candidate cancers using feature parameters. First, we calculate 13 feature parameters containing 4 new parameters that we have defined. These new parameters were designed to reflect the shape features of candidate cancers less than 10 mm in diameter; specifically, revised circularity, modified elongation, convexity, and the ratio of convergent figures. Next, candidate cancers were divided into 4 classes based on the area and the thickness parameter, and cancers and false positives were distinguished based on the values of the feature parameters in each class. This reduction method was applied to LSCT images of 83 samples, and the method reduced the total number of candidate cancers from 12399 to 977. The average number of false positives per sample was 10.7, without any additional false positives. These results show the effectiveness of the proposed method. (author)

    Full Text Available Endobronchial tuberculosis and chest radiography I read, with interest, the article entitled “Clinical and Para-clinical Presentations of Endobronchial Tuberculosis” by Ahmadi Hoseini H. S. et al. (1 published in this journal. I would like to focus on some details about the chest X-ray of patients as elaborated by the authors in the results section. Accordingly, the findings of chest radiography in the available patients were as follows: pulmonary consolidation (75%, reduced pulmonary volume (20%, and hilar adenopathy (10%. This is an incomplete statement because the authors did not explain whether there was any normal chest radiography in the study population. In addition, it is not clear whether the X-ray examinations of the patients were normal, how many abnormal plain films yielded the presented data. On the other hand, the fact that the studied patients had no normal chest radiography is  controversial since in the literature, 10-20% of the patients with endobronchial tuberculosis are reported to have normal chest X-ray (2, 3. In fact, this is one of the problems in the diagnosis of the disease, as well as a potential cause of delayed diagnosis and treatment of the patients. Therefore, the absence of normal chest radiographs is in contrast to the available literature, and if not an error, it could be a subject of further investigation.

  17. Accuracy of non-contrast-enhanced and contrast-enhanced CT in the diagnosis of blunt renal trauma. JAST renal injury classification consideration

    International Nuclear Information System (INIS)

    Although many reports have described the diagnostic role of computed tomography (CT) scans in renal trauma, these reports only discuss the use of contrast-enhanced (CE) CT. We compared the diagnostic value of non-contrast-enhanced (NE) CT with that of CECT in 50 consecutive renal injuries. Additionally, we discuss the implications of CT findings on the controversy surrounding the Japanese Association for the Surgery of Trauma (JAST) renal injury classification system. All hematomas viewed using CECT (low density) were also cleary observed using NECT (high density). The actual size of the hematoma was more accurately demonstrated using NECT. Detecting small hematomas using CECT was sometimes difficult, and a considerable number of small injuries were only visible using NECT. If only CECT was performed, perirenal hematomas were sometimes underestimated and parenchymal lacerations were sometimes overestimated. CECT was superior to NECT for the diagnosis of active bleeding or pedicle injury. The purpose of the JAST classification system must be clarified and appropriate diagnosis methods included. If the purpose of this classification is the degree of severity for the subsequent management strategy, CECT is sufficient. However, we believe that the subdivisions for subcapsular injury are unnecessary and that the severity of renal artery occlusion should be reconsidered. If the purpose is just the morphological diagnosis, NECT is also required for an accurate diagnosis. (author)

  19. Imaging of thoracic trauma

    International Nuclear Information System (INIS)

    Blunt trauma to the chest results from transfer of kinetic energy to the human body. It may cause a wide range of mostly life-threatening injuries, including fractures of the thoracic skeleton, disintegration of the pleural space, contusion or laceration of pulmonary parenchyma and damage to the mediastinal structures. For a systematic approach it may be helpful to follow an organ-based evaluation of thoracic trauma. However, it should be borne in mind that subtle injuries may be associated with serious complications. Trauma to the chest may affect different anatomic compartments at the same time, requiring and extending diagnostic approach. Conventional radiography plays a major role in diagnosting thoracic trauma, complemented by ultrasound examination of the pleura and abdomen. It is well documented that CT scanning represents a major technological improvement for assessment of thoracic trauma. With the advent of fast helical CT scanning this method becomes more applicable for severly traumatized patients and potentially replaces other time-consuming procedures. State-of-the-art imaging of both projection and cross-sectional techniques provides useful information for immediate and appropriate treatment mandatory in patients with thoracic trauma. (orig.)

    Full Text Available A 32 year old female presented with dry cough and progressive breathlessness of one year duration. There was no history suggestive of collagen vascular disease, lung parenchymal infection or allergic airway disease. Clinical evaluation showed basal fine inspiratory crepitations. Radiographic examination of the chest revealed a black pleura line and lung parenchymal calcification. CT scan of the chest demonstrated nodular calcification of lung parenchyma with a “crazy pavement” pattern, which is suggestive of alveolar calcification. Pulmonary function test showed a severe restrictive defect. On transbronchial lung biopsy calcific spherules suggestive of the alveolar microlithiasis were seen. Diagnosis of pulmonary alveolar microlithiasis was made and symptomatic treatment was given, as there is no specific therapy available. The case illustrates an unusual cause of shortness of breath in a young female with striking radiographic features.

    Blunt renal trauma is the third most common injury in abdominal trauma following splenic and hepatic injuries, respectively. In the majority, such injuries are associated with other abdominal organ injuries. As urological injuries are not usually life-threatening, and clinical signs and symptoms are non-specific, diagnosis is often delayed. We present a practical approach to the diagnosis and management of these injuries based on our experience in a busy inner city trauma hospital with a review of the current evidence-based practice. Diagnostic imaging signs are illustrated.

    Linguistic characteristics of trauma narratives have been linked to the development and severity of posttraumatic stress disorder (PTSD). However, it remains unclear if linguistic markers of PTSD exist beyond the scope of trauma narratives. This study used ambiguous visual prompts to elicit spontaneous narratives from trauma-exposed individuals with (n = 23) and without PTSD (n = 30). Individuals with PTSD used more singular pronouns and death-related words, and fewer plural pronouns. Within the PTSD group, increased severity of reexperiencing symptoms was associated with greater use of singular pronouns and lower use of cognitive words; increased severity of avoidance symptoms was associated with lower use of death words; and increased severity of hyperarousal symptoms was associated with less frequent use of anxiety words. Together, these linguistic variables accounted for 53% of the variance in total PTSD symptom severity. These findings are consistent with previous research suggesting that language use is a strong predictor of PTSD psychopathology, and extend the evidence to include the linguistic characteristics of non-trauma-related narratives.

    2014-07-01

    Full Text Available Currently, a large burden of hospital admissions is related to minor head trauma and its related imaging studies. One of the challenging issues for emergency physicians is brain computed tomography scan. Sensible use of computed tomography studies could minimize unnecessary radiation exposure and resource use. On the other hand, it can result in delayed or missed early treatment of intracranial injury. The aim of this review is to evaluate and summarize the costs and benefits of using diagnostic measurements in minor head trauma with particular focus on computed tomography scan and the advances and limitations of available guidelines. We studied different issues related to the current approach to minor head trauma in emergency departments. Altogether, it seems using brain computed tomography scan in the setting of emergency is a cost-effective method for the selected patients with minor head injury. However, concerning considerable costs of caring for patients with head injury and high sensitivity of brain computed tomography in terms of minor head injury, it seems reasonable to use brain computed tomography scan for a wider range of patients with minor head injury.

    In closed chest trauma, bronchial rupture is an unusual but potentially serious complication, with an associated mortality rate of 30%. Recent decades have seen an increase in incidence parallel to greater use of transport. Eighty percent of injuries are located 2.5 cm from the carina. Diagnosis is based on clinical signs, imaging and bronchoscopy. Subcutaneous emphysema and respiratory insufficiency are the most common findings. Images show the presence of pneumothorax, pneumomediastinum or both. Bronchoscopy is the diagnostic method of choice and must be performed early. Treatment consists of reestablishing anatomical continuity of the tracheobronchial tree by surgical repair if the lesion affects more than a third of the circumference and/or pneumothorax is not resolved after two chest drainages. This type of injury should be recognized and treated early, both to restore lung function and to prevent associated complications caused by delay. However, initial findings are seldom specific, requiring the physician to display a high degree of suspicion and explaining why diagnosis often comes late. PMID:11171438

    Pattern approach to the diagnosis of lung diseases based on CT scan appearances. Guide to quick and reliable differential diagnosis. CT-pathology correlation. Emphasis on state-of-the-art MDCT. The purpose of this atlas is to illustrate how to achieve reliable diagnoses when confronted by the different abnormalities, or ''disease patterns'', that may be visualized on CT scans of the chest. The task of pattern recognition has been greatly facilitated by the advent of multidetector CT (MDCT), and the focus of the book is very much on the role of state-of-the-art MDCT. A wide range of disease patterns and distributions are covered, with emphasis on the typical imaging characteristics of the various focal and diffuse lung diseases.

    Full Text Available In any patient with a history of penetrating thoracic trauma, cardiac injury must be kept in mind. Here, we describe a 36 years-old female referred to this hospital with severe chest pain and hypotension. After primary evaluation and suggestion of AMI, streptokinase was started for the patient and because of deterioration of vital signs, cardiac surgery consultation was requested. After performing urgent echocardiography, massive pericardial tamponade was detected. Visualization of a knife blade on C.X.R and past medical history of thoracic stab injury led to a diagnosis of delayed cardiac tamponade and urgent sternotomy was performed. The blade that had penetrated the right ventricular chamber was extracted. Six days after operation, patient was discharged without any problem. This case study suggests the importance of high suspicion to cardiac injury in any patient with chest pain and a history of chest trauma.

  18. Bone scintigraphy as an aid in the diagnosis of occult distal tarsal bone trauma in three horses

    International Nuclear Information System (INIS)

    History, physical examination, and bone scintigraphy were used to diagnose central and/or third tarsal bone trauma in 3 acutely lame horses. In all 3 cases, the results of initial radiographic examination were negative. Bone scintigraphy revealed focal, intense radioisotope uptake at the level of the distal tarsal bones in the 3 horses. Radiographs obtained 4 weeks after injury in one horse demonstrated a slab fracture of the central tarsal bone. Conservative management of the tarsal bone disease resulted in acceptable return to function in all 3 horses

  19. A Comparison between Dual-Exposure Dual-Energy Radiography and Standard Chest Radiography for the Diagnosis of Small Pulmonary Nodules

    International Nuclear Information System (INIS)

    To evaluate the utility of dual-exposure dual-energy radiography against the standard chest radiography in the discrimination of lung nodules and the presence of nodule calcification. Twenty-nine patients with a total of 43 peripheral lung nodules were examined by dual-exposure dual-energy radiography (DER) and confirmed by a chest CT were included in the study. Of the identified peripheral lung nodules, 24 showed calcification and 19 did not. Further, 28 lesion-free regions from the same patient population were selected as negative controls. Two radiologists evaluated 71 marked locations using both standard chest radiographs (SR) and DER to determine whether the marked locations represented a true nodule, and whether nodule calcification was present. A continuous rating scale of 0-10 was used to represent each observer's confidence level. We calculated the areas under ROC curves (AUC) for SR alone and for DER, and performed a statistical analysis to compare the results. The ability to discriminate nodules was higher for DER than for SR. However, the was not statistically significant (p = 0.202). Inter-observer agreement was moderate regardless of if DER was used. The predictability of nodule calcification was significantly higher for DER compared to SR (p < .001). Moreover, inter-observer agreement was slight with SR alone but moderate with DER. DER, in conjunction with SR, has no additional benefit in small lung nodule discrimination but does provide a significant benefit in the characterization of nodule calcification

    Full Text Available FUNDAMENTO: A radiografia de tórax e o eletrocardiograma (ECG tem sido criticados em razão de sua baixa sensibilidade no diagnóstico da Hipertrofia Ventricular Esquerda (HVE quando comparada ao ecocardiograma. Entretanto, esse exame não está disponível nos centros de atendimento primário para toda a população de hipertensos. OBJETIVO: Avaliar se a radiografia de tórax associada ao eletrocardiograma apresenta acurácia que justifique seu uso na detecção de HVE em hipertensos, bem como a utilidade do índice cardiotorácico e das radiografias oblíquas na avaliação das dimensões das câmaras cardíacas esquerdas. MÉTODOS: Estudo prospectivo realizado em 177 pacientes hipertensos consecutivos, através da radiografia do tórax, eletrocardiograma e ecocardiograma. Testes de acurácia foram utilizados para comparar esses métodos utilizando a ecocardiografia convencional como padrão de referência. RESULTADOS: O índice cardiotorácico mostrou sensibilidade de 17% para o diagnóstico de HVE, somente detectando alterações cardíacas mais acentuadas. As incidências póstero-anterior e perfil tiveram sensibilidade de 52%, aumentando para 54% quando a radiografia de tórax foi associada ao eletrocardiograma. As incidências oblíquas não melhoraram significativamente a acurácia da radiografia de tórax que, por sua vez, apresentou alta especificidade e boa sensibilidade para a detecção do aumento da aorta. Foi interessante notar que essa alteração estava presente em metade dos hipertensos com HVE. CONCLUSÃO: A associação da radiografia de tórax com eletrocardiograma é útil na avaliação inicial de hipertensos para o diagnóstico de hipertrofia ventricular esquerda, especialmente se a ecocardiografia não estiver disponível.

    2008-11-01

    Full Text Available Abstract Background Low energy trauma to the upper extremity is rarely associated with a significant vascular injury. Due to the low incidence, a high level of suspicion combined with appropriate diagnostic algorithms are mandatory for early recognition and timely management of these potentially detrimental injuries. Methods Review of the pertinent literature, supported by the presentation of two representative "near miss" case examples. Results A major diagnostic pitfall is represented by the insidious presentation of significant upper extremity arterial injuries with intact pulses and normal capillary refill distal to the injury site, due to collateral perfusion. Thus, severe vascular injuries may easily be missed or neglected at the upper extremity, leading to a long-term adverse outcome with the potential need for a surgical amputation. Conclusion The present review article provides an outline of the diagnostic challenges related to these rare vascular injuries and emphasizes the necessity for a high level of suspicion, even in the absence of a significant penetrating or high-velocity trauma mechanism.

  2. Blunt thoracic trauma - an analysis of 264 patients in Rawalpindi, Pakistan

    International Nuclear Information System (INIS)

    Objective: To analyse the outcome in terms of morbidity and mortality in blunt thoracic trauma patients in tertiary care hospitals, Rawalpindi. Methods: The prospective study was conducted from March 2008 to February 2012 in surgical wards of public and private sector hospitals in Rawalpindi. A total of 221 patients were included from the Combined Military Hospital during 2008-10, and 43 patients from the Heart's International during 2011-12. The patients reported to emergency department within 48 hours of trauma. All patients were subjected to detailed history and respiratory system examination to ascertain fracture of ribs, flail segment and haemopneumothorax. The diagnosis of chest wall injuries, parenchymal pulmonary injuries and pleural involvement were made on the basis of chest radiographs and computed tomography scan of the chest. The lung contusion was assessed by the number of lobes involved. SPSS 19 was used for statistical analysis. Results: Of the 264 patients in the study, 211 (80%) were males and 54 (20%) females. The overall mean age was 44.8+-17.1 years. Over all morbidity was 222 (84.2%); morbidity (minor) was 128 (48.5%), and morbidity (major) was 94 (35.7%). Mortality was 26 (9.8%) and 16 (6%) cases had normal outcome. Conclusion: Early identification and aggressive management of blunt thoracic trauma is essential to reducing significant rates of morbidity and mortality. (author)

  3. CT detection of occult pneumothorax in head trauma

    International Nuclear Information System (INIS)

    A prospective evaluation for occult pneumothorax was performed in 25 consecutive patients with serious head trauma by combining a limited chest CT examination with the emergency head CT examination. Of 21 pneuomothoraces present in 15 patients, 11 (52%) were found only by chest CT and were not identified clinically or by supine chest radiograph. Because of pending therapeutic measures, chest tubes were placed in nine of the 11 occult pneumothoraces, regardless of the volume. Chest CT proved itself as the most sensitive method for detection of occult pneumothorax, permitting early chest tube placement to prevent transition to a tension pneumothorax during subsequent mechanical ventilation or emergency surgery under general anesthesia

  5. Abdominal trauma

    International Nuclear Information System (INIS)

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

    Full Text Available Thomas P Vacek, Shahnaz Rehman, Shipeng Yu, Ankush Moza, Ragheb Assaly Department of Internal Medicine, The University of Toledo Medical Center, Toledo OH, USAAbstract: Chest pain requires a detailed differential diagnosis with good history-taking skills to differentiate between cardiogenic and noncardiogenic causes. Moreover, when other symptoms such as fever and elevated white blood cell count are involved, it may be necessary to consider causes that include infectious sources. A 53-year-old female with no significant past medical history returned to the hospital with recurrent complaints of chest pain that was constant, substernal, reproducible, and exacerbated with inspiration and expiration. The chest pain was thought to be noncardiogenic, as electrocardiography did not demonstrate changes, and cardiac enzymes were found to be negative for signs of ischemia. The patient's blood cultures were analyzed from a previous admission and were shown to be positive for Staphylococcus aureus. The patient was started empirically on vancomycin, which was later switched to ceftriaxone as the bacteria were more sensitive to this antibiotic. A transthoracic echocardiogram did not demonstrate any vegetation or signs of endocarditis. There was a small right pleural effusion discovered on X-ray. Therefore, computed tomography as well as magnetic resonance imaging of the chest were performed, and showed osteomyelitis of the chest. The patient was continued on intravenous ceftriaxone for a total of 6 weeks. Tests for HIV, hepatitis A, B, and C were all found to be negative. The patient had no history of childhood illness, recurrent infections, or previous trauma to the chest, and had had no recent respiratory infections, pneumonia, or any underlying lung condition. Hence, her condition was thought to be a case of primary sternal osteomyelitis without known cause.Keywords: substernal, pleuritic, myocardial infarction, differential

    High-pressure waves (blast) account for the majority of combat injuries and are becoming increasingly common in terrorist attacks. To our knowledge, there are no data evaluating the epidemiology of blast injury in a domestic nonterrorist setting. Data were analyzed retrospectively on patients admitted with any type of blast injury over a 10-year period at a busy urban trauma center. Injuries were classified by etiology of explosion and anatomical location. Eighty-nine cases of blast injury were identified in 57,392 patients (0.2%) treated over the study period. The majority of patients were male (78%) with a mean age of 40 +/- 17 years. The mean Injury Severity Score was 13 +/- 11 with an admission Trauma and Injury Severity Score of 0.9 +/- 0.2 and Revised Trauma Score of 7.5 +/- 0.8. The mean intensive care unit and hospital length of stay was 2 +/- 7 days and 4.6 +/- 10 days, respectively, with an overall mortality rate of 4.5 per cent. Private dwelling explosion [n = 31 (35%)] was the most common etiology followed by industrial pressure blast [n = 20 (22%)], industrial gas explosion [n = 16 (18%)], military training-related explosion [n = 15 (17%)], home explosive device [n = 8 (9%)], and fireworks explosion [n = 1 (1%)]. Maxillofacial injuries were the most common injury (n = 78) followed by upper extremity orthopedic (n = 29), head injury (n = 32), abdominal (n = 30), lower extremity orthopedic (n = 29), and thoracic (n = 19). The majority of patients with head injury [28 of 32 (88%)] presented with a Glasgow Coma Scale score of 15. CT scans on admission were initially positive for brain injury in 14 of 28 patients (50%). Seven patients (25%) who did not have a CT scan on admission had a CT performed later in their hospital course as a result of mental status change and were positive for traumatic brain injury (TBI). Three patients (11%) had a negative admission CT with a subsequently positive CT for TBI over the next 48 hours. The remaining four patients (14

  8. Urogenital trauma: imaging upper GU trauma

    International Nuclear Information System (INIS)

    Objectives: This article will define the current controversies and concepts in the classification, clinical presentation, imaging approaches and management of upper urinary tract trauma. Materials and methods, results: This review will include the experience of the authors in the field of renal trauma over a 32-year period. Current thinking accepts the view that significant renal trauma is generally present when there is gross hematuria, signs of shock, or other clinical signs of severe injury. In most patients, suspected renal injury will be evaluated as a part of the overall assessment of the patient for suspected intraperitoneal injury. The authors will stress some exceptions to the rule. Conclusions: Most trauma experts now advocate conservative management, unless the patient is unstable or a renal vascular thrombosis or avulsion is suspected. Similarly, penetrating trauma to the kidney in and of itself no longer requires mandatory surgery. In the United States, computed tomography (CT), especially spiral CT, is considered the best diagnostic study, if available. Intravenous pyelography (IVP) is adequate if this is the only imaging modality available and if no concomitant injuries to the abdominal structure are suspected. Ultrasound, although strongly advocated in some countries, can lead to some significant false negatives. The diagnosis and management of unusual problems such as the traumatic AV fistula, the patient with an absent kidney or injury to the congenitally abnormal kidney, the serendipitous renal tumor in a patient with trauma, or serious bleeding after an apparent minor injury (i.e., spontaneous hemorrhage) are also reviewed in this article

O sucesso no tratamento conservador dos pacientes com trauma renal depende de um acurado estadiamento da extensão da lesão, classificado de acordo com a Organ Injury Scaling do Colégio Americano de Cirurgiões. O tratamento conservador não-operatório é seguro e consiste de observação contínua, repouso no leito, hidratação endovenosa adequada e antibioti- coterapia profilática, evitando-se uma exploração cirúrgica desnecessária e possível perda renal. As indicações para exploração cirúrgica imediata são abdome agudo, rápida queda do hematócrito ou lesões associadas determinadas na avaliação radiológica. Quando indicada, a exploração renal após controle vascular prévio é segura, permitindo cuidadosa inspeção do rim e sua reconstrução com sucesso, reduzindo a probabilidade de nefrectomia.We present a revision of the renal trauma with emphasis in the radiographic evaluation, particularly CT scan that it has largely replaced the excretory urogram and arteriogram in the diagnostic worh-up and management of the patient with renal trauma.

    Chest pain is one of themost common complaints expressed by patients presenting to the emergency department, and any initial evaluation should always consider life-threatening causes. Esophageal rupture is a serious condition with a highmortality rate.

    Lenfant, Claude

    2010-10-01

    Chest pain is one of the most common symptoms driving patients to a physician's office or the hospital's emergency department. In approximately half of the cases, chest pain is of cardiac origin, either ischemic cardiac or nonischemic cardiac disease. The other half is due to noncardiac causes, primarily esophageal disorder. Pain from either origin may occur in the same patient. In addition, psychological and psychiatric factors play a significant role in the perception and severity of the chest pain, irrespective of its cause. Chest pain of ischemic cardiac disease is called angina pectoris. Stable angina may be the prelude of ischemic cardiac disease; and for this reason, it is essential to ensure a correct diagnosis. In most cases, further testing, such as exercise testing and angiography, should be considered. The more severe form of chest pain, unstable angina, also requires a firm diagnosis because it indicates severe coronary disease and is the earliest manifestation of acute myocardial infarction. Once a diagnosis of stable or unstable angina is established, and if a decision is made not to use invasive therapy, such as coronary bypass, percutaneous transluminal coronary angioplasty, or stent insertion, effective medical treatment of associated cardiac risk factors is a must. Acute myocardial infarction occurring after a diagnosis of angina greatly increases the risk of subsequent death. Chest pain in women warrants added attention because women underestimate their likelihood to have coronary heart disease. A factor that complicates the clinical assessment of patients with chest pain (both cardiac and noncardiac in origin) is the relatively common presence of psychological and psychiatric conditions such as depression or panic disorder. These factors have been found to cause or worsen chest pain; but unfortunately, they may not be easily detected. Noncardiac chest pain represents the remaining half of all cases of chest pain. Although there are a number of

    Full Text Available Background: Although there have been significant advances in the management of traumatic brain injury (TBI, associated severe injuries, in particular chest injuries, remain a major challenge. This paper analyses the contribution of chest injuries to the outcome of head injuries in the University of Nigeria Teaching Hospital (UNTH and the Memfys Hospital for Neurosurgery (MHN in Enugu, Nigeria. Materials and Methods: This is a retrospective review of the medical records, operative notes, and radiological findings of all patients admitted for head injury who had associated significant chest injuries in the MHN from 2002 to 2009 and the UNTH between 2007 and 2010. Patients with only head injury and other extracranial injury not affecting the chest were excluded. Patients who were inadequately investigated were also excluded. Results: Nineteen patients from the MHN and 11 patients from the UNTH were analyzed. Ages ranged from 9 to 65 years and the male:female ratio was 3:1. Injuries were most common between 30 and 50 years and road traffic accident accounted for 60%. Barotrauma from ventilation was documented in 2 patients. The commonest types of intrathoracic injuries are pneumothorax and hemothorax. Chest wall injuries are more common but carry less morbidity and mortality. Only 20% of patients presented within 48 hours of injury. Management of the associated chest trauma commenced in the referring hospitals only in 26.4% of the patients. All patients with hemo-pneumothorax had tube thoracostomy as did 96% of patients with pneumothorax. 10% of patients with haemothorax needed thoracotomy. Mortality is 43%, which is higher than for patients with only TBI with comparable Glasgow coma scale. Outcome is influenced by the time to admission and the GCS on admission. Conclusion: Associated chest injuries result in higher mortality from head injuries. This association is more likely in the young and more productive. All patients presenting with head and

    Full Text Available ABSTRACT Background: Chest radiography accounts for a significant proportion of ionising radiation in children. The radiation dose of radiographs performed on the Lodox Statscan system has been shown to be lower than that of a computed radiography (CR system. The role of the Lodox Statscan (hereafter referred to as the Statscan in routine erect chest radiography in children has not been evaluated. Objective: To evaluate the image quality and diagnostic accuracy of erect paediatric chest radiographs obtained with the Statscan and compare this with conventional erect chest images obtained with a CR system. Materials and Methods: Thirty three children with suspected chest pathology were enrolled randomly over a period of three months. Erect chest radiographs were obtained with the Statscan, and a Shimadzu R-20J X-ray machine coupled with a Fuji FCR 5000 CR system. Image quality and diagnostic accuracy and diagnostic capability were evaluated between the two modalities. Results: The erect Statscan allowed superior visualisation of the three major airways. Statscan images however, demonstrated exposure and movement artifacts with hemidiaphragms and ribs most prone to movement. Bronchovascular clarity was also considered unsatisfactory on the Statscan images. Conclusion: The Statscan has limitations in erect chest radiography in terms of movement artefacts, exposure fluctuations, and poor definition of lung markings. Despite this, the Statscan allows better visualisation of the major airways, equivalent to a ‘high KV’ film at a fraction of the radiation dose. This supports the finding of an earlier study evaluating Statscan images in trauma cases, where the images were taken supine. Statscan has great potential in assisting in the diagnosis of childhood tuberculosis where airway narrowing occurs as a result of nodal compression.

    Objective: To analyze the data of trauma patients with thoracic injury in the earthquake of Bam admitted to hospitals of Tehran University of Medical Science (TUMS)for better understanding the type and consequence of thoracic injuries in a major earthquake.Methods: After Bam earthquake registering 6.5 on the Richter scale, 526 trauma patients were admitted to hospitals of TUMS. Among them, 53 patients sustained thoracic injury.Results: This group was composed of 21 females (39.6%) and 32 males (60.4%). Fifteen patients (28.3%) had isolated chest injuries. Rib fracture (36.4%) was the most common injury in our patients and haemo/pneumothorax (25.5%) followed. Superficial injury was the most common accompanying injury. Multipletrauma patients with chest injury had higher injury severity score (ISS) versus patients with isolated chest injury (P =0.003).Conclusions: Chest wall injuries and haemo/pneumothorax comprise a considerable number of injuries in survival victims of earthquakes. Consequently, the majority of these patients can be treated with observation or tube thoracostomy. We should train and equip the health workers and members of rescue teams to treat and manage these patients in the field.

The sensitivity, specificity, negative predictive value and positive predictive value of ultrasonography in the diagnosis of free abdominal fluid were respectively, 84%, 86%, 91% and 75%, which were respectively, 54%, 90%, 65% and 79% in the diagnosis of intra abdominal damage. "nConclusion: Ultrasonography has sensitivity, specificity and enough accuracy to detect free abdominal fluid in blunt abdominal trauma in comparison with CT-scan in the children's and adult's age group which if combined with abdominal viscera parenchymal abnormalities, these parameters would sensitively increase in the children's age group."nKeywords: CT Scan, Ultrasonography, Abdominal Blunt Trauma, Sensitivity, Specificity

  2. CT quantification of pleuropulmonary lesions in severe thoracic trauma

    International Nuclear Information System (INIS)

    Purpose: Computed quantification of the extent of pleuropulmonary trauma by CT and comparison with conventional chest X-ray - Impact on therapy and correlation with mechanical ventilation support and clinical outcome. Method: In a prospective trial, 50 patients with clinically suspicious blunt chest trauma were evaluated using CT and conventional chest X-ray. The computed quantification of ventilated lung provided by CT volumetry was correlated with the consecutive artificial respiration parameters and the clinical outcome. Results: We found a high correlation between CT volumetry and artificial ventilation concerning maximal pressures and inspiratory oxygen concentration (FiO2, Goris-Score) (r=0.89, Pearson). The graduation of thoracic trauma correlated highly with the duration of mechanical ventilation (r=0.98, Pearson). Especially with regard to atelectases and lung contusions CT is superior compared to conventional chest X-ray; only 32% and 43%, respectively, were identified by conventional chest X-ray. (orig./AJ)

    Substantial theoretical, empirical, and clinical work examines trauma as it relates to individual victims and perpetrators. As trauma professionals, it is necessary to acknowledge facets of institutions, cultures, and communities that contribute to trauma and subsequent outcomes. Systemic trauma-contextual features of environments and institutions that give rise to trauma, maintain it, and impact posttraumatic responses-provides a framework for considering the full range of traumatic phenomena. The current issue of the Journal of Trauma & Dissociation is composed of articles that incorporate systemic approaches to trauma. This perspective extends conceptualizations of trauma to consider the influence of environments such as schools and universities, churches and other religious institutions, the military, workplace settings, hospitals, jails, and prisons; agencies and systems such as police, foster care, immigration, federal assistance, disaster management, and the media; conflicts involving war, torture, terrorism, and refugees; dynamics of racism, sexism, discrimination, bullying, and homophobia; and issues pertaining to conceptualizations, measurement, methodology, teaching, and intervention. Although it may be challenging to expand psychological and psychiatric paradigms of trauma, a systemic trauma perspective is necessary on both scientific and ethical grounds. Furthermore, a systemic trauma perspective reflects current approaches in the fields of global health, nursing, social work, and human rights. Empirical investigations and intervention science informed by this paradigm have the potential to advance scientific inquiry, lower the incidence of a broader range of traumatic experiences, and help to alleviate personal and societal suffering.

    To study the effect of increasing the spatial resolution on thin section (1.5 mm) computed tomography (CT) of the chest, we compared images reconstructed with the standard algorithm (SA) to three other images obtained with (1) a high spatial frequency algorithm, (2) retrospective targeting to a small field of view (FOV) reconstructed with the high spatial frequency algorithm, and (3) the same high spatial frequency algorithm with images acquired with the small (0.6 mm) rather the large (0.9 mm) focal spot. Examinations were performed on a phantom, on normal subjects, and on patients with emphysema and other diffuse lung diseases. Modulation transfer function (MTF) calculations revealed that higher resolution was achieved on the small focal spot and high spatial frequency algorithm than on the standard algorithm. Evaluation of the four images from 25 normal subjects, 16 patients with emphysema and 9 with interstitial disease was performed by means of an ROC study. Results from the areas under the ROC curves, sensitivity and specificity have shown that images reconstructed with the high spatial frequency algorithm were preferred. We conclude that the use of a high spatial frequency algorithm increases spatial resolution and improves visibility of lung parenchyma. Although more evaluation is needed, the potential of increasing spatial resolution further by using a smaller focal spot is currently limited by the mas Available per slice and the associated increased level of quantum noise.

    International Nuclear Information System (INIS)

    The diagnosis of trauma to the spine - where the slightest oversight may have catastrophic results - requires a thorough grasp of the spectrum of resultant pathology as well as the imaging modalities used in making an accurate diagnosis. In Spinal Trauma, the internationally renowned team of experts provides a comprehensive, cutting-edge exposition of the current vital role of imaging in the diagnosis and treatment of injuries to the axial skeleton. Beginning with a valuable clinical perspective of spinal trauma, the book offers the reader a unique overview of the biomechanics underlying the pathology of cervical trauma. Acute trauma topics include: - Optimization of imaging modalities - Malalignment - signs and significance - Vertebral fractures - detection and implications - Classification of thoraco-lumbar fractures - rationale and relevance - Neurovascular injury. Distilling decades of clinical and teaching expertise, the contributors further discuss the current role of imaging in special focus topics, which include: - The pediatric spine - Sports injuries - The rigid spine - Trauma in the elderly - Vertebral collapse, benign and malignant - Spinal trauma therapy - Vertebral fractures and osteoporosis - Neuropathic spine. All throughout the book, the focus is on understanding the injury, and its implications and complications, through 'an imaging approach'. Lavishly illustrated with hundreds of superb MR images and CT scans, and clear full-color drawings, the authors conclude with a look into the future, defining clinical trends and research directions. Spinal Trauma - with its broad scope, practical imaging approach, and current focus - is designed to enhance confidence and accuracy, making it essential reading for clinicians and radiologists at all levels.

    Full Text Available OBJECTIVE: To determine the sensitivity and specificity of a Computer Aided Diagnosis (CAD program for scoring chest x-rays (CXRs of presumptive tuberculosis (TB patients compared to Xpert MTB/RIF (Xpert. METHOD: Consecutive presumptive TB patients with a cough of any duration were offered digital CXR, and opt out HIV testing. CXRs were electronically scored as normal (CAD score ≤ 60 or abnormal (CAD score > 60 using a CAD program. All patients regardless of CAD score were requested to submit a spot sputum sample for testing with Xpert and a spot and morning sample for testing with LED Fluorescence Microscopy-(FM. RESULTS: Of 350 patients with evaluable data, 291 (83.1% had an abnormal CXR score by CAD. The sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV of CXR compared to Xpert were 100% (95%CI 96.2-100, 23.2% (95%CI 18.2-28.9, 33.0% (95%CI 27.6-38.7 and 100% (95% 93.9-100, respectively. The area under the receiver operator curve (AUC for CAD was 0.71 (95%CI 0.66-0.77. CXR abnormality correlated with smear grade (r = 0.30, p<0.0001 and with Xpert CT(r = 0.37, p<0.0001. CONCLUSIONS: To our knowledge this is the first time that a CAD program for TB has been successfully tested in a real world setting. The study shows that the CAD program had high sensitivity but low specificity and PPV. The use of CAD with digital CXR has the potential to increase the use and availability of chest radiography in screening for TB where trained human resources are scarce.

  11. Radiology of maxillofacial trauma

    International Nuclear Information System (INIS)

    The maxillofacial skeleton is very vulnerable to injury. The face is a favorite target of blows in assaults or fights and is a primary site of traumatic injury in automobile accidents. Although most injuries can be diagnosed clinically, radiologic imaging is pivotal in the diagnosis and management of these injuries. The accurate diagnosis and complete evaluation of maxillofacial trauma require a comprehensive knowledge of maxillofacial anatomy and an understanding of the mechanisms of maxillofacial injury. The role and efficacy of plain film radiography, thin-section multiplanar tomography, and CT in the diagnosis and management of facial fractures is discussed. CT has proved superior to the other imaging modalities in maxillofacial trauma, especially in complex maxillofacial injuries. The value of CT is stressed and demonstrated

    Full Text Available The purpose of this article is to depict the spectrum of scrotal injuries in blunt trauma. Scrotal injuries are not very common and are mostly due to blunt trauma from direct injury, sports injuries or motor vehicle accidents. To minimize complications and ensure testicular salvage, rapid and accurate diagnosis is necessary. High-resolution USG is the investigation of choice, as it is readily available, accurate and has been seen to improve outcomes. An understanding of and familiarity with the sonographic appearance of scrotal injuries on the part of the radiologist/sonographer is therefore of key importance.

    Scimitar syndrome is a rare, combined abnormality of bronchopulmonary development and pulmonary vascular development characterized by an anomalous pulmonary venous return to the inferior vena cava. Although the scimitar syndrome has been associated with many anomalies, a tracheoesophageal fistula (TEF), especially from H-type, is extremely rare and only a few cases have been reported without detailed descriptions. Herein we report a rare case of scimitar syndrome with H-type TEF and multiple anomalies in a newborn infant, with a special emphasis on the imaging features associated with the radiologic diagnosis using an electrocardiography-gated computed tomography.

  20. Ultrasonography in the diagnosis of traumatic hemothorax

    International Nuclear Information System (INIS)

    Full text: The possibilities and advantages of US tomography in the diagnosis and follow-up of traumatic hemothorax in major trauma patients were presented. US examinations of the chest in conditions of emergency with purpose to identify hemothorax were performed in 56 (41 male and 15 female patients for a period of two years.US machine 'Siemens-Adara' supplied with 3.5 and 7 MHz linear and convex transducers was used. The right and left intercostal oblique view was used for US examination to identify free pleural fluid. Tube thoracotomy and/or a CT scan of the chest were used as the criterion standard for positive findings of hemothorax among the studied patients. In 49 (87.5%) of all 56 major trauma patients was achieved true-positive diagnostic result of hemothorax confirmed in 39 cases post operatively and in 10 after investigation by CT. In 6 (10.71%) patients - true-negative and in 1 (1.7%) false negative results were obtained. Our experience demonstrated that US is a sensitive, specific, and accurate diagnostic method in detecting traumatic hemothorax. The advantages of US tomography in the diagnosis of traumatic hemothorax are: First - the examination is not influenced by the position of the patient: Second - the rapidity of examination is 2-4 min and simultaneously differentiation of dense regions. Third - the possibility to present small amount of liquid collections 20-30 cc

  1. Endovascular interventions for multiple trauma

    International Nuclear Information System (INIS)

    In recent years interventional radiology has significantly changed the management of injured patients with multiple trauma. Currently nearly all vessels can be reached within a reasonably short time with the help of specially preshaped catheters and guide wires to achieve bleeding control of arterial und venous bleeding. Whereas bleeding control formerly required extensive open surgery, current interventional methods allow temporary vessel occlusion (occlusion balloons), permanent embolization and stenting. In injured patients with multiple trauma preinterventional procedural planning is performed with the help of multidetector computed tomography whenever possible. Interventional radiology not only allows minimization of therapeutic trauma but also a considerably shorter treatment time. Interventional bleeding control has developed into a standard method in the management of vascular trauma of the chest and abdomen as well as in vascular injuries of the upper and lower extremities when open surgical access is associated with increased risk. Additionally, pelvic trauma, vascular trauma of the superior thoracic aperture and parenchymal arterial lacerations of organs that can be at least partially preserved are primarily managed by interventional methods. In an interdisciplinary setting interventional radiology provides a safe and efficient means of rapid bleeding control in nearly all vascular territories in addition to open surgical access. (orig.)

  2. Radiographic evaluation of hepatic trauma

    International Nuclear Information System (INIS)

    The incidence of significant abdominal trauma continues to rise and accounts currently for approximately 10 percent of the annual 130,000 trauma-related deaths in the United States. Over 60 percent of patients are from 10 to 40 years of age, with a striking predominance of males. Children are mostly victims of blunt trauma, while some large reviews of liver trauma in adults show a prevalence of penetrating injuries. Injury to the liver is second only to the spleen in incidence of intraperitoneal injuries. Morbidity and mortality from hepatic trauma are related to the mechanism and extent of injury. Penetrating injuries generally have a lower mortality, about 5 percent, especially if they are due to stab wounds or low velocity gunshot wounds. Shotgun and high velocity gunshot wounds may cause massive fragmentation of the liver and are associated with proportionately greater mortality. The mortality from blunt trauma is from 15 to 45 percent in many large series. Death from isolated liver injury is uncommon, but is usually due to uncontrolled hemorrhage. Injury to other abdominal organs is associated in many cases, as are injuries to the head, chest, and limbs. The extraabdominal injuries are frequently more apparent clinically, but may mask potentially life-threatening abdominal visceral injuries

    Accidental injuries are the leading cause of death in the 15 to 44-year-old age group. Blunt chest trauma is often encountered in these patients and is associated with a mortality of up to 25%. Although conventional radiography still plays an important role in the initial emergency room setting, for follow-up in the intensive care unit, multidetector computed tomography has established itself as the standard imaging method for the evaluation of chest trauma patients. The following review presents salient radiological findings of the chest wall and shoulder girdle, thoracic spine, pleural space, and lung in polytraumatized patients.

  7. Abdominal trauma

    International Nuclear Information System (INIS)

    Radiologic evaluation of abdominal trauma must provide a quick and accurate assessment of the lesions in order to improve the management of the patient. The technique used varies depending on the mechanism of the trauma (blunt trauma or stab wounds) and the hemodynamic status. Radiologic evaluation is usually performed in blunt trauma whereas stab wound trauma is usually explored surgically. The various techniques available are standard radiographs, ultrasonography, computed tomography and arteriography. The role of magnetic resonance imaging in the immediate evaluation is still not well defined. It appears to be useful method in the delayed evaluation of diaphragmatic trauma. Computed tomography is the method most commonly performed in trauma patients. This technique is accurate and allows correct assessment of the lesions. The disadvantages are the radiation induced and the need for a hemo-dynamically stable patient. The aim of the radiologic evaluation is to provide the clinicians with an accurate description of the lesions. It can help in the management of the patient usually in association with clinical and laboratory data. It can also guide interventional procedures (drainage, embolization...). Finally, it allows radiographic follow-up when conservative treatment is performed. (authors). 26 refs., 11 figs., 1 tab

  8. The blunt abdominal trauma

    International Nuclear Information System (INIS)

    Up to 1970 the number of patients suffering from blunt abdominal trauma showed a substantial increase. In more than 50% of all cases there are additional injuries. The most important factor influencing the prognosis of these patients is the early and correct indication for operation and the avoidance of unnecessary laparotomies. As a primary aim in diagnosis one should consider the recognition of an intraperitoneal bleeding without risk for the patient. Peritoneal lavage as an invasive method with low complication rates has proved good. First reports also show good results using the sonography of the abdomen. The recognition of the injured organ allows a carefully directed operation. Concerning the prognosis it is of minor importance. The diagnosis in patients with blunt abdominal trauma at the university clinic of Freiburg consists of: sonography, followed in positive cases by laparotomy or angiography and laparotomy. In cases with questionable results a lavage is done. (orig.)

    Chest pain is one of themost common complaints expressed by patients presenting to the emergency department, and any initial evaluation should always consider life-threatening causes. Esophageal rupture is a serious condition with a highmortality rate. If diagnosed, successful therapy depends on the size of the rupture and the time elapsed between rupture and diagnosis.We report on a 41-year-old woman who presented to the emergency department complaining of left-sided chest pain for two hours.

    International Nuclear Information System (INIS)

    Bronchial rupture is a rare and serious complication of blunt chest trauma in children. The diagnosis of this injury is challenging and requires a high degree of clinical suspicion. It is frequently associated with other severe injuries that may draw the focus of attention away from this potentially catastrophic but treatable injury. The radiographic findings of bronchial rupture have been reported in very few series. We report the findings in two children with bronchial rupture diagnosed by CT, in whom CT resulted in a significant change in patient management. (orig.)

    Introduction: Pneumothorax is defined as the presence of air in the pleural cavity, ie, the space between the chest wall and the lung itself. Pneumothorax is classified ethiologically into spontaneous pneumothorax and traumatic pneumothorax. Spontaneous pneumothorax is further classified into primary and secondary. Traumatic pneumothorax may result from either blunt trauma or penetrating injury to the chest wall. It can also be caused by iatrogenic injuries. Spontaneous pneumothorax is a sign...

    Full Text Available Abstract Keloid formation is one of the most challenging clinical problems in wound healing. With increasing frequency of open heart surgery, chest keloid formations are not infrequent in the clinical practice. The numerous treatment methods including surgical excision, intralesional steroid injection, radiation therapy, laser therapy, silicone gel sheeting, and pressure therapy underscore how little is understood about keloids. Keloids have a tendency to recur after surgical excision as a single treatment. Stretching tension is clearly associated with keloid generation, as keloids tend to occur on high tension sites such as chest region. The authors treated 58 chest keloid patients with surgical excision followed by intraoperative and postoperative intralesional steroid injection. Even with minor complications and recurrences, our protocol results in excellent outcomes in cases of chest keloids.

  2. Computed tomography whole body imaging in multi-trauma: 7 years experience

    International Nuclear Information System (INIS)

    AIM: To assess the impact of the introduction of a computed tomography (CT) imaging protocol for multi-trauma patients on the workload, overall diagnostic yield, and effect on detection of cervical spine injury and pneumothorax. METHOD: Between February 1997 and April 2004, all patients presenting acutely to the Emergency Department (ED) with haemodynamically stable trauma (Abbreviated Injury Scale 3 or more) involving more than two body systems were imaged with a comprehensive pre-set helical CT protocol (including non-contrast head, cervical spine: cranio-cervical and cervico-thoracic junctions; and oral and intravenous contrast-enhanced thoracic, abdomen and pelvis) after initial triage and a standard trauma series of radiographs (chest, lateral C-spine and pelvis). Diagnosis of cervical spine fracture and pneumothorax was noted before and after the CT protocol was carried out and findings from all studies were recorded prospectively. RESULTS: Over the 7-year period 296 multi-trauma CT studies were completed of which 41 (13.8%) were negative. Of the positive cases there were 127 (43%) head injuries; 25 cervical spine fractures (8%); 66 pelvic fractures (22%);48 thoracic or lumbar spine fractures (16%); 97 pneumothoraces (33%); 22 mediastinal injuries (7%) and 49 intra-abdominal injuries (17%) with 19 (6%) splenic tears/ruptures. Positive findings included many unsuspected injuries, including 19 cervical spine fractures which were not demonstrated on the standard lateral radiograph from the resuscitation room. Of the 97 CT detected pneumothoraces, 12 were bilateral, 52 already had a chest drain in situ and 36 were not detected on initial supine chest radiography in the resuscitation room. One undetected case had bilateral tension pneumothoraces that were promptly drained on the CT table. Only three patients did not complete their multi-trauma examination because of deterioration in clinical condition and these were all immediately returned to the resuscitation

Optimal timing of trauma alerts could improve team preparedness and performance while also limiting adverse ripple effects throughout the hospital. The purpose of this study was to evaluate how timing of trauma team activation and notification affects initial in-hospital management of trauma patients.Methods: Data from a single hospital trauma care quality registry were matched with data from a trauma team alert log. The time from patient arrival to chest X-ray, and the emergency department length of stay were compared with the timing of trauma team activations and whether or not trauma team members received a preactivation notification.Results: In 2009, the trauma team was activated 352 times; 269 times met the inclusion criteria. There were statistically significant differences in time to chest X-ray for differently timed trauma team activations (P = 0.003. Median time to chest X-ray for teams activated 15–20 minutes prearrival was 5 minutes, and 8 minutes for teams activated <5 minutes before patient arrival. Timing had no effect on length of stay in the emergency department (P = 0.694. We found no effect of preactivation notification on time to chest X-ray (P = 0.474 or length of stay (P = 0.684.Conclusion: Proactive trauma team activation improved the initial management of trauma patients. Trauma teams should be activated prior to patient arrival.Keywords: emergency medical service communication systems

  7. A Review of Esophageal Chest Pain.

    Coss-Adame, Enrique; Rao, Satish S C

    2015-11-01

    Noncardiac chest pain is a term that encompasses all causes of chest pain after a cardiac source has been excluded. This article focuses on esophageal sources for chest pain. Esophageal chest pain (ECP) is common, affects quality of life, and carries a substantial health care burden. The lack of a systematic approach toward the diagnosis and treatment of ECP has led to significant disability and increased health care costs for this condition. Identifying the underlying cause(s) or mechanism(s) for chest pain is key for its successful management. Common etiologies include gastroesophageal reflux disease, esophageal hypersensitivity, dysmotility, and psychological conditions, including panic disorder and anxiety. However, the pathophysiology of this condition is not yet fully understood. Randomized controlled trials have shown that proton pump inhibitor therapy (either omeprazole, lansoprazole, or rabeprazole) can be effective. Evidence for the use of antidepressants and the adenosine receptor antagonist theophylline is fair. Psychological treatments, notably cognitive behavioral therapy, may be useful in select patients. Surgery is not recommended. There remains a large unmet need for identifying the phenotype and prevalence of pathophysiologic mechanisms of ECP as well as for well-designed multicenter clinical trials of current and novel therapies.

  8. The role of interventional radiology in trauma

    International Nuclear Information System (INIS)

    This is a lecture on the role of interventional radiology in trauma. Trauma is classified into either blunt with a wide distribution of force to the patient or penetrating which has a narrower and knifing type of presentation. Penetrating trauma requires the tissues injured be fully examined by both cross-sectional imaging and, if hemorrhage is occurring, by arteriography where as blunt trauma is not so localized and requires the examination of much wider area of the body. Embolization of any bleeding site should occur at the time of diagnosis. embolization should be accomplished using either gelfoam or stainless or platinum coils. The treatments of pelvic trauma, renal trauma and ceres bral trauma are introduced in detail in this lecture

  9. Anterior chest wall examination reviewed

    2011-09-01

    Full Text Available Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondiloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the “activity” of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

  10. CHEST PHYSIOTHERAPY FOR INFANTS

    Directory of Open Access Journals (Sweden)

    Preeti S. Christian (M.P.T Cardiopulmonary Conditions

    2014-10-01

    Full Text Available In the normal lung, secretions are removed by Mucociliary activity, normal breathing cycles, and cough. In disease, increased secretion viscosity and volume, dyskinesia of the cilia, and ineffective cough combine to reduce the ability to clear secretions, and may increase exacerbations and infections. Many chest physiotherapy techniques like postural drainage, percussion and vibration are used since many years. These techniques are derived from adult studies but these techniques are quite stressful for the infants as the infant respiratory system is different from the adult respiratory system. Advance chest physiotherapy techniques were developed specifically for infants; in accordance with their physiological characteristics. So this review is to introduce some new chest physiotherapy helpful for newborn infants.

    2016-04-01

    Necrotizing fasciitis (NF) is a bacterial dermo-hypodermitis affecting the soft tissue and muscular fascia. It is an uncommon and severe infection caused by microorganisms called 'flesh eating bacteria', mainly represented by group A beta-haemolytic streptococcus. NF remains a life-threatening condition associated with a high mortality rate. Its location on the chest wall is extremely rare. The few reported cases are subsequent to thoracic drainage, lung surgery or esophageal resection. This is a case report of an 80-year old female with comorbidity of heart disease, a past history of coronary artery by-pass and diabetes. She was admitted to the emergency room with acute NF of the chest and shortly after diagnosis, the patient died. Due to the fast decline observed in this disease, we would like to emphasize the importance of early recognition and diagnosis. PMID:27323534

    2011-02-01

    Full Text Available Traumatic ventricular septal defect (VSD resulting from blunt chest injury is a very rare event. The mechanisms of traumatic VSD have been of little concern to dateuntil now, but two dominant theories have been described. In one, the rupture occurs due to acute compression of the heart; in the other, it is due to myocardial infarction of the septum. The clinical symptoms and timing of presentation are variable, so appropriate diagnosis can be difficult or delayed. Closure of traumatic VSD has been based on a combination of heart failure symptoms, hemodynamics, and defect size. Here, we present a case of a 4-year-old boy who presented with a traumatic VSD following a car accident. He showed normal cardiac structure at the time of injury, but after 8 days, his repeated echocardiography revealed a VSD. He was successfully treated by surgical closure of the VSD, and has been doing well up to the present. This report suggests that the clinician should pay great close attention to the patients injured by blunt chest trauma, keeping in mind the possibility of cardiac injury.

  1. Liver trauma from penetrating injuries. Miscellanea, personal series, clinical and CT findings

    International Nuclear Information System (INIS)

    Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. In this report are examined the clinical and radiological findings of personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. It will also tried to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. In the last seven years it was retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different cases. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the mid-chest for accurate assessment of diaphragm and lung bases and to exclude associated pleuropulmonary damage. Penetrating liver wounds were caused by firearms in 70% of cases, by stabbing in 12% and, in the extant 18%, by other cases such as home accidents, road and work traumas, and liver biopsy. In this series, the liver was most frequently involved, especially by firearms wounds; in the 16 cases the most frequent injuries were hemorrhagic tears. It was found bullets in the liver in 6 cases. In one case of home accident the patient wounded himself while slicing bread with a long knife, which cut into the anterior abdominal wall and tore the anterior liver capsule, as seen at CTA. Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of

    Trauma - accidental or intentional injury - is a major health and social problem. It is still the chief cause of death in people between the ages of 1 and 38 years. In the United States, the mortality due to trauma between the ages of 15 and 24 years increased by 13% from 1960 to 1978. During the same period, the mortality for people aged 25 to 64 years declined by 16%. Murders have increased from 8464 in 1960, to 26 000 in 1982. The overall death rate of American teenagers and young adults is 50% higher than that of their counterparts in Britain, Sweden and Japan. Trauma affects young, productive citizens, and the estimated costs for death, disability and loss of productivity exceed $230 million a day. The most tragic statistic is that at least 40% of the deaths are needless and preventable if better treatment and prevention programs were available. Trauma deaths that might be prevented are those due to motor vehicle accidents, homicide, burns, and alcohol and drug abuse. In this paper suggestions for prevention are made. They include improved crash worthiness of motor vehicles, revocation of drunk drivers' licences, use of devices that limit drunk drivers, increased tax on alcohol and random breathalyser tests, and the use of seat belts and motorcycle helmets. Control of hand-guns and burn characteristics of cigarettes could also reduce deaths. The problems and issues in trauma care can be divided into two broad categories: system and professional. System problems include prehospital care, in-hospital care, rehabilitation and prevention. Professional problems include education, research, economics, and quality.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:6478325

    International Nuclear Information System (INIS)

    severe osteoporosis are readily identified with skeletal scintigraphy. In marathon runners rhabdomyolysis can be diagnosed by skeletal scintigraphy as areas of local increased radiotracer uptake in the exercise-damages skeletal muscles. Another use of skeletal scintigraphy in trauma is the assessment of hip prosthesis and differentiation between osteotomy and prosthesis loosening. Some other applications of skeletal scintigraphy are detection of enthuse pat hies, Avulsion Injuries and other athletic lesions.

    International Nuclear Information System (INIS)

    Chest X-ray in newborns and infants shows great differences to that in adults. Therefore all radiologists, who engage in X-rays in this age group, must be familiar with the special features. At the beginning specific items of examination methods are explained, which must be strictly followed due to radiological protection. Focus of the paper is the discussion of the important chest diseases in newborn and infants, which are mostly unknown in chest diagnosis in adults. Many of them can be life-threatening, thus their knowledge is essential. Pathophysiological explanations shall make the special radiological signs understandable. (orig.)

    Full Text Available Objective: To observe difference in the management of blunt trauma to the chest on the basis of conventional xray and computerised tomography of the chest. Methods: This prospective study was conducted between December 2011 to October 2012 in COMS in Bharatpur,a tertiary referral centre in central Nepal . Clinically stable thoracic injury patients were first evaluated with chest x-ray and the management on this basis was recorded. The findings of the CT chest were assessed and the type of management on the basis of CT was also recorded. Outcome was assessed in terms of mortality, morbidity, hospital and ICU stay with respect to the management on the basis of chest x-ray and CT scan. Results: Of the 129 patients, 74.4% were male and 25.6% were female with the patients ranging in age from 7 to 87 years (mean = 40.41 years. The most common mechanism of trauma to the chest was as a result of a motor vehicle accident (69.8%, followed by fall injury (20.2%. X-ray chest diagnosed rib fracture in 62%, haemothorax in 37%, pneumothorax in 27%, lung contusion in 10% and haemopneumothorax in 21% patients. Similarly CT chest diagnosed rib fracture in 86%, haemothorax in 54%, pneumothorax in 36%, lung contusion in 30% and haemopneumothorax in 30% patients. Mean hospital stay was 9.5 days in the group of patients having management on the basis of x-ray chest relative to mean stay of 10.2 days in the CT- chest group. In the management on the basis of xray group, there was a mean ICU stay of 2.8days compared to mean stays of 3.2 days in CT chest group. Conclusion: Though CT scan of the chest is more informative and differs the management of the blunt chest trauma, one should not forget to advise the cost effective, easily available and initial guiding agent, xray chest for early management of the chest injury patient.

  12. Importance of multidetector CT imaging in multiple trauma

    International Nuclear Information System (INIS)

    Diagnostic imaging of complex multiple trauma remains a challenge for any department providing modern emergency radiology (ER) service. An early and comprehensive approach for ER imaging is crucial for a priority-oriented and timely therapy concept with the aim of identifying potentially life-threatening injuries early and initiating appropriate treatment. The basic diagnostic approach still consists of focused ultrasound using focused assessment with sonography for trauma (FAST) and conventional radiography (CR), usually limited to a single supine chest x-ray for triaging patients undergoing immediate operations. Multidetector computed tomography (MDCT) has become established as early whole body CT (WBCT) as the undisputable diagnostic method. The detection rate of injuries by WBCT is outstanding and it improves the probability of survival by 20-25 % compared with all other previous methods. At the same time, the spatial and temporal resolution of MDCT was improved resulting in considerably shortened examination times but WBCT is still associated with a significant radiation exposure, even in the acute single use setting. Using modern scanner and dose reduction technology, including iterative reconstruction, a dose reduction of up to 40 % could be achieved. The substantial number of images in WBCT is another challenge; images must be processed priority-oriented, read and transferred to the picture archiving and communications system (PACS). For rapid diagnosis, volume image reading (VIR) offers additional options to keep the diagnostic process on time. Modern WBCT after multiple trauma is performed early, comprehensively and personalized so that WBCT improves the probability of survival by 20-25 %. (orig.)

  13. Pediatric digital chest imaging

    International Nuclear Information System (INIS)

    The Philips Computed Radiography system performs well with pediatric portable chest radiographs, handling the throughout of a busy intensive care service 24 hours a day. Images are excellent and routinely provide a conventional (unenhanced) image and an edge-enhanced image. Radiation dose is decreased by the lowered frequency of repeat examinations and the ability of the plates to respond to a much lower dose and still provide an adequate image. The high quality and uniform density of serial PCR portable radiographs greatly enhances diagnostic content of the films. Decreased resolution has not been a problem clinically. Image manipulation and electronic transfer to remote viewing stations appear to be helpful and are currently being evaluated further. The PCR system provides a marked improvement in pediatric portable chest radiology

    External laryngeal trauma is a rare but potentially life-threatening situation in the acutely injured patient. Trauma mechanism and magnitude, maximum focus of the applied force, and patient related factors, such as age and ossification of the laryngeal cartilages influence the spectrum of observed injuries. Their correct diagnosis and prompt management are paramount in order to avoid patient death or long-term impairment of breathing, swallowing and speaking. The current review provides a comprehensive approach to the radiologic interpretation of imaging studies performed in patients with suspected laryngeal injury. It describes the key anatomic structures that are relevant in laryngeal trauma and discusses the clinical role of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the acute emergency situation. The added value of two-dimensional multiplanar reconstructions (2D MPR), three-dimensional volume rendering (3D VR) and virtual endoscopy (VE) for the non-invasive evaluation of laryngeal injuries and for treatment planning is discussed. The clinical presentation, biomechanics of injury, diagnostic pitfalls and pearls, common and uncommon findings are reviewed with emphasis of fracture patterns, involvement of laryngeal joints, intra- and extralaryngeal soft tissue injuries, and complications seen in the acute emergency situation. The radiologic appearance of common and less common long-term sequelae, as well as treatment options are equally addressed.

  18. Blunt abdominal trauma in adults: role of CT in the diagnosis and management of visceral injuries. Part 1. Liver and spleen

    International Nuclear Information System (INIS)

    Computed tomography is now widely used in the initial diagnostic workup of adult trauma victims with suspected intra-abdominal injuries. We review the role of CT in the detection and management of blunt visceral injuries in two parts. In the first part we discuss general aspects of performing CT in the setting of abdominal trauma and the diagnostic findings of intra-abdominal hemorrhage and blunt hepatic and splenic injuries. Hepatic and splenic injuries can be detected by means of CT with a high accuracy. The vast majority of hepatic injuries can be successfully managed conservatively, even when CT demonstrates parenchymal damage of more than three segments and major hemoperitoneum. Delayed complications, e. g., formation of biloma or a false aneurysm, can be readily detected on repeat CT studies, although they are quite uncommon. The outcome of conservative treatment of splenic injuries remains unpredictable because delayed splenic rupture may occur even when initial CT shows only minor parenchymal lesions and little or no intraperitoneal hemorrhage.

    Full Text Available A feared complication to liver trauma is delayed vascular complication, such as pseudoaneurysm and arteriovenous fistula (PS/AF seen as focal enhancement on contrast-enhanced computed tomography (CT in the arterial phase. A hyperdense area termed transient hepatic attenuation difference (THAD representing altered hepatic blood flow can be seen in the arterial phase near the liver lesion. The objective of this study was to describe THAD and PS/AF on follow-up CT after blunt liver trauma, and to evaluate if THAD influenced the evaluation of PS/AF. Three radiology residents retrospectively evaluated scans of 78 patients. The gold standard for PS/AF was an evaluation by an experienced senior radiologist, while THAD was a consensus between the residents. PS/AF was present in 14% and THAD in 54%. THAD was located in the periphery of the lesion with hazy borders and mean HU levels of 100, while PS/AF was located within the lesion with focal enhancement and mean HU levels of 170 (p < 0.05. In evaluation of PS/AF, the likelihood of agreement between the observers and the gold standard was 89% when THAD was present, and 98% when THAD was absent (p = 0.04. THAD is common and can hamper the evaluation of PS/AF.

    Geriatric patients are at increased risk for serious morbidity and mortality from life-threatening causes of chest pain. This article covers 5 life-threatening causes of chest pain in the elderly: acute coronary syndrome, aortic dissection, pulmonary embolism, pneumothorax, and esophageal rupture. Atypical presentations, frailty, and significant comorbidities that characterize the elderly make the diagnosis and treatment of these already complicated conditions even more complicated. The emergency provider must be vigilant and maintain a low threshold to test. When a diagnosis is made, treatment must be aggressive. The elderly benefit from optimal care. PMID:27475013

  2. Interdisciplinary shock-room care: tasks for the radiologist from the viewpoint of the trauma surgeon

    International Nuclear Information System (INIS)

    Efficient resuscitation of major trauma requests an interdisciplinary communication between trauma surgeons, anaesthesiologists and radiologists. Trauma outcome is significantly influenced by horizontal trauma team organisation and coherence to clinical algorithms, which allow fast diagnosis and intervention. A radiologist present on patients arrival in the trauma room provides a major impact on trauma care. Nevertheless optimal integration in the trauma team implies profound knowledge of the priorities of advanced trauma life support and trauma algorithms. His or her involvement is not limited to patient care only, also active participation in trauma room design, interdisciplinary algorithm development and trauma research are essential tasks for radiologists devoted to emergency radiology. Based on the pathophysiology of polytrauma and the structure of German trauma system, current concepts and proven clinical algorithms with special regard to the radiologist and his duties and tasks will are presented.

    Despite the improvement of medical treatment for acute coronary syndromes throughout the 20th century, the authors believe that many cases of life-threatening coronary events could be avoided through early detection of CAD and the use of preventive strategies. Establishing chest pain units that are linked to the ED is one excellent strategy to risk-stratify patients with symptoms who are at risk for sustaining an AMI or having lethal arrhythmias. There is a need for more research on chest pain units to determine the value for cost and to further optimize strategies for ACI detection and screening. In EDs with high volumes of chest pain patients, or high pressures to avoid hospital admissions, a planned, systematic, and rapid approach to the treatment of AMI and the diagnosis of chest pain is a rewarding necessity.

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

    Establishing post-traumatic stress disorder as a psychiatric diagnosis has only marginally increased awareness of traumatic experiences. Traumas are inconsistently recorded in initial psychiatric histories and, when observed, rarely reflected in the primary diagnosis and treatment. The present study aimed to investigate if there is an association between sufficiently addressing trauma and long-term outcome and what factors affect whether trauma, according to the patient's view, is sufficiently addressed or not. Socio-demographic data, experiences of trauma and treatment, and outcome, were collected retrospectively from Arabic, Iranian, Turkish and Swedish patients, who had visited a psychiatric clinic 3-4 years earlier. Fifty-one patients whose traumatic experiences had been sufficiently addressed were compared with 39 patients who perceived that their traumas had not been addressed. Logistic regression analyses were performed to examine relationships between clinical variables and whether or not traumas had been addressed. Patients with trauma sufficiently addressed reported high confidence in staff (odds ratio, OR=7.2, pSwede (OR=2.4, p<0.10) were the background variables independently related to having trauma sufficiently addressed. Addressing trauma may improve patients' confidence in staff, self-rated health and trauma-related symptoms. Multiplicity of traumas and belonging to an ethnic minority implied that trauma was less addressed. PMID:15370780

  10. Dose and perceived image quality in chest radiography

    International Nuclear Information System (INIS)

    Chest radiography is the most commonly performed diagnostic X-ray examination. The radiation dose to the patient for this examination is relatively low but because of its frequent use, the contribution to the collective dose is considerable. Consequently, optimization of dose and image quality offers a challenging area of research. In this article studies on dose reduction, different detector technologies, optimization of image acquisition and new technical developments in image acquisition and post processing will be reviewed. Studies indicate that dose reduction in PA chest images to at least 50% of commonly applied dose levels does not affect diagnosis in the lung fields; however, dose reduction in the mediastinum, upper abdomen and retrocardiac areas appears to directly deteriorate diagnosis. In addition to patient dose, also the design of the various digital detectors seems to have an effect on image quality. With respect to image acquisition, studies showed that using a lower tube voltage improves visibility of anatomical structures and lesions in digital chest radiographs but also increases the disturbing appearance of ribs. New techniques that are currently being evaluated are dual energy, tomosynthesis, temporal subtraction and rib suppression. These technologies may improve diagnostic chest X-ray further. They may for example reduce the negative influence of over projection of ribs, referred to as anatomic noise. In chest X-ray this type of noise may be the dominating factor in the detection of nodules. In conclusion, optimization and new developments will enlarge the value of chest X-ray as a mainstay in the diagnosis of chest diseases.

    Trauma is the most common cause of death in childhood, and abusive head trauma is the most common cause of traumatic death and morbidity in infants younger than 1 year. The main differential diagnosis of abusive head trauma is accidental traumatic brain injury, which is usually witnessed. This paper also discusses more uncommon diagnoses such as congenital and acquired disorders of hemostasis, cerebral arteriovenous malformations and metabolic diseases, all of which are extremely rare. Diagnostic imaging including CT and MRI is very important for the distinction of non-accidental from accidental traumatic injury. (orig.)

    Slipping rib syndrome is an overlooked cause of persistent abdominal or chest pain. The etiology of this syndrome is not well understood, but the characteristic pain is from hypermobility of the false ribs. Although it is a diagnosis of exclusion, misdiagnosis may lead to an excessive workup. A simple clinical examination via the hooking maneuver is the most significant feature of its diagnosis. We describe the case of a 41-year-old woman with slipping rib syndrome. PMID:26528703

    Full Text Available Abstract Background Quality control of trauma care is essential to define the effectiveness of trauma center and trauma system. To identify the troublesome issues of the system is the first step for validation of the focused customized solutions. This is a comparative study of two level I trauma centers in Italy and Romania and it has been designed to give an overview of the entire trauma care program adopted in these two countries. This study was aimed to use the results as the basis for recommending and planning changes in the two trauma systems for a better trauma care. Methods We retrospectively reviewed a total of 182 major trauma patients treated in the two hospitals included in the study, between January and June 2002. Every case was analyzed according to the recommended minimal audit filters for trauma quality assurance by The American College of Surgeons Committee on Trauma (ACSCOT. Results Satisfactory yields have been reached in both centers for the management of head and abdominal trauma, airway management, Emergency Department length of stay and early diagnosis and treatment. The main significant differences between the two centers were in the patients' transfers, the leadership of trauma team and the patients' outcome. The main concerns have been in the surgical treatment of fractures, the outcome and the lacking of documentation. Conclusion The analyzed hospitals are classified as Level I trauma center and are within the group of the highest quality level centers in their own countries. Nevertheless, both of them experience major lacks and for few audit filters do not reach the mmum standard requirements of ACS Audit Filters. The differences between the western and the eastern European center were slight. The parameters not reaching the minimum requirements are probably occurring even more often in suburban settings.

Diagnostic predictive values, sensibility and specificity are greater than when obtained by the other diagnostic methods such as peritoneal lavage, ultrasonography and computed tomography. Despite their limitations, when indicated for selected patients seems to reduce non terapeutic laparotomies, postoperative morbidity, hospital stay and costs. The authors present a review of the literature regarding videolaparoscopy in the abdominal trauma, its limitations and complications. Based an a complex protocol for the indications of videolaparoscopy for abdominal trauma, the authors sugested their exclusive use by level trauma centers.

  1. Renal trauma in adults - a pictorial review

    International Nuclear Information System (INIS)

    Full text: This review provides a framework for understanding the classification and features of renal trauma. Computed tomography (CT) is now the modality of choice in prompt diagnosis and staging of renal trauma. A retrospective review of the CT scans of all patients with blunt abdominal trauma sustaining renal injury that presented to our hospital within the last 2 years was undertaken. The patient list was obtained from our Trauma Registry database at the Trauma Services Unit. Representative cases of each category of renal injury are displayed on a poster, accompanied by explanatory notes. We also reviewed the literature on renal trauma between 1985-2001 on Medline. The indications for radiological assessment and the management of renal trauma remain controversial. Staging of renal trauma with CT imaging, when integrated with clinical information helps to facilitate appropriate management plan. Renal injuries are classified into four grades on the basis of imaging: - Grade 1: Minor cortical contusion, minor laceration with limited perinephric hematoma, and small cortical infarct. - Grade 2: Major renal lacerations extending to the medulla with or without involvement of the collecting system and segmental renal infarct. - Grade 3: Catastrophic injury which include multiple renal lacerations and injury to the renal vascular pedicle. - Grade 4: Ureteropelvic junction injuries. Diagnostic imaging and staging plays a major role in assessing patients with renal injuries and affects clinical management decisions. Understanding the radiologic classification of traumatic renal injuries and integrating the findings with clinical information assist in developing an optimal management plan.

    The morbidity, mortality, and economic costs resulting from trauma in general, and blunt abdominal trauma in particular, are substantial. The "panscan" (computed tomographic [CT] examination of the head, neck, chest, abdomen, and pelvis) has become an essential element in the early evaluation and decision-making algorithm for hemodynamically stable patients who sustained abdominal trauma. CT has virtually replaced diagnostic peritoneal lavage for the detection of important injuries. Over the past decade, substantial hardware and software developments in CT technology, especially the introduction and refinement of multidetector scanners, have expanded the versatility of CT for examination of the polytrauma patient in multiple facets: higher spatial resolution, faster image acquisition and reconstruction, and improved patient safety (optimization of radiation delivery methods). In this article, the authors review the elements of multidetector CT technique that are currently relevant for evaluating blunt abdominal trauma and describe the most important CT signs of trauma in the various organs. Because conservative nonsurgical therapy is preferred for all but the most severe injuries affecting the solid viscera, the authors emphasize the CT findings that are indications for direct therapeutic intervention.

    We report 2 cases of surgical treatment of blunt cardiac trauma. The postoperative course was uneventful in either case. Pericardial drainage in patients with cardiac rupture should be performed with preparation for thoracotomy. Case 1: A 34-year-old male, hit in the chest by a collapsing 700-kg steel rod, was transported to our hospital via ambulance. The patient was diagnosed as having a cardiac rupture by echocardiography and underwent emergency thoracotomy. The right atrium near the inferior vena cava (IVC) was damaged, though bleeding from the wound had already ceased. No suture hemostusis was needed. Case 2: A 63-year-old female was hit by a car and transported to our hospital due to blunt trauma to the chest. Low blood pressure and chest computed tomography demonstrated cardiac tamponade, and subxiphoid pericardial drainage was performed. Blood pressure was recovered, but persistent hemorrhage necessitated emergency thoracotomy, which revealed a laceration at the right atrium near IVC. The injury was sutured to achieve complete hemostasis. PMID:18323181

  6. Percutaneous artherial embolization in the treatment of liver trauma

    International Nuclear Information System (INIS)

    Percutaneous arterial embolization in the treatment of liver trauma. Liver trauma requires emergency therapy. Because it is highly vascular and because of its location, the hemostasis is difficult to achieve. The main causes of death associated to liver trauma are due to prolonged hipovolemia. The current forms of surgical treatment of liver wounds are associated with a high morbidity rate. In some hepatic injuries, hemorrage is so massive that operative control of bleeding is necessary, bu t in most cases, particularly in blunt trauma, an angiographic approach with diagnosis and embolotherapy is preferable. Six patients with blunt or perforating hepatic trauma were managed with percutaneous arterial embolization. Hemostasis was achieved immediately in all of them withoyt recurrence. Surgical intervention with additional trauma was thus avoided, decreasing the morbidity rate. The percutaneous arterial embolization presents an efficient alternative in the management of hemorrage due to liver trauma, being particularly useful in the poor risk patient. (author)

    In this study we examined the relationship between posttrauma pathology and the level of articulation (complexity) in rape narratives recounted by victims shortly after the assault. Degree of articulation was operationalized as the reading level of the narrative as determined by a computer program. Shortly after the trauma, reading level was correlated with severity of anxiety but not with posttraumatic stress disorder (PTSD) symptoms. Degree of the narrative articulation shortly after the trauma, however, was related to severity of later PTSD. These results are consistent with the hypothesis that the less developed trauma narratives hinder recovery from trauma. PMID:9565923

    Background: Blunt chest trauma (BCT) poses significant morbidity and mortality worldwide. Objectives: We investigated the clinical presentation and outcome of BCT related to road traffic accidents (RTA). Patients and Methods: A retrospective observational analysis for patients who sustained BCT secondary to RTA in terms of motor vehicle crash (MVC) and pedestrian-motor vehicle accidents (PMVA) who were admitted to the trauma center at Hamad general hospital, Doha, Qatar, between 2008 and 2011. Results: Of 5118 traumatic injury cases, 1004 (20%) were found to have BCT secondary to RTA (77% MVC and 23% PMVA). The majority were males (92%), and expatriates (72%). Among MVCs, 84% reported they did not use protective devices. There was a correlation between chest abbreviated injury score (AIS) and injury severity scoring (ISS) (r = 0.35, r2 = 0.12, P < 0.001). Regardless of mechanism of injury (MOI), multivariate analysis showed that the head injury associated with chest AIS and ISS was a predictor of mortality in BCT. Overall mortality was 15%, and the highest rate was observed within the first 24 hours post-trauma. Conclusions: Blunt chest trauma from RTA represents one-fifth of the total trauma admissions in Qatar, with a high overall mortality. Pedestrians are likely to have more severe injuries and higher fatality rates than MVC victims. Specific injury prevention programs focusing on road safety should be implemented to minimize the incidence of such preventable injuries.

    1993-01-01

    This review of early care covers issues pertaining to the analysis of system function, prehospital intravascular volume replacement, diagnosis of proximity vascular injury, the role of emergency thoracotomy, and the value of transesophageal echocardiography. The first six articles deal with various aspects of system function, from triage to analysis of outcome. The next series of articles reviews work in progress evaluating optimal fluid for resuscitation. Hypertonic saline and dextran combinations have been shown to restore vital signs better than isotonic solutions; they are safe, require smaller volumes, and may improve head injury outcome. Danger lies in the restoration of perfusion without hemorrhage control. Two articles on emergency thoracotomy review the indications and outcome in blunt and penetrating trauma. Survival in blunt trauma is virtually zero. An article and two editorials summarize state of the art for diagnosis and treatment of proximity vascular injury. Two articles describe the potential use of the new technique of transesophageal echocardiography. This new modality has not formed a solid indication at present and can be considered investigational in trauma care. PMID:7584006

    Full Text Available A Actinomicose é uma infecção rara, crônica, supurativa e granulomatosa que pode envolver diversos órgãos. A infecção pulmonar geralmente está relacionada à imunodepressão e à saúde bucal precária. O envolvimento torácico é incomum (10 - 20%, a parede torácica é acometida em apenas 12% destes casos. No presente trabalho, é descrito o caso de um paciente de 26 anos, não HIV e sem co-morbidades, assintomático respiratório, com massa infra-escapular, de crescimento progressivo, muito dolorosa, com sinais locais flogísticos, sem trauma local, apresentando febre persistente, com três meses de evolução. O diagnóstico inicial foi de neoplasia de partes moles de parede torácica. À biopsia incisional da referida massa, houve saída de secreção gelatinosa vinhosa com grânulos amarelados, sugestivos de actinomicose, sendo confirmado por exame anatomopatológico. Empiricamente foi instituída ciprofloxacina devido alergia à cefalosporina. Houve excelente resposta clínica à drenagem externa e à medicação prescrita. Não houve recaída da doença em 18 meses de seguimento.Actinomycosis is an uncommon suppurative granulomatous chronic infection that may involve several organs. Lung infection is usually related to immunodepression and poor oral hygiene. Cases of thoracic involvement are rare (10 - 20% and only 12% of such cases affect the chest wall. This report describes the case of a 26-year-old HIV-negative patient without comorbidities or respiratory complaints who presented a very painful, progressively growing infrascapular mass, with local phlogistic signs and no local trauma, and persistent fever. It had been progressing for three months. The initial diagnosis was neoplasia of chest wall soft tissue. However, incision biopsy in this mass produced a red wine-colored gelatinous secretion containing yellowish granules suggestive of actinomycosis, which was later confirmed by anatomopathological examination

    2015-01-01

    Full Text Available A 41-year-old man experienced a swollen scrotum three days after a motorcycle accident and presented to our hospital. He had had a primary suture repair for anoperineal trauma in an outside hospital at the time of the injury. He presented to us with general fatigue, low grade fevers, and perineal pain. Abdominal computed tomography showed subcutaneous emphysema from the scrotum to the left chest. The sutured wound had foul-smelling discharge and white exudate. We made the diagnosis of necrotizing fasciitis and immediately opened the sutured wound and performed initial debridement and lavage with copious irrigation. We continued antibiotics and lavage of the wound until the infection was controlled. Fortunately, the necrotizing fasciitis did not worsen and he was discharged after 15 days. Our experience indicates that anoperineal injuries should not be closed without careful and intensive follow-up due to the potential of developing necrotizing fasciitis.

  15. Adhesive intestinal obstruction following blunt abdominal trauma

    International Nuclear Information System (INIS)

    Advances in diagnosis and management of multiple trauma patients have lead to adopting a conservative approach for most patients with blunt abdominal trauma. Intestinal obstruction is a rare complication for this approach. Herein, we report a 37-year-old male, who did not have an abdominal operation, and who developed adhesive intestinal obstruction 7 weeks following blunt abdominal trauma. We detected no signs of peritonitis or intra-abdominal bleeding clinically or radiologically on admission. We initially treated the intestinal obstruction conservatively, but the obstruction did not resolve. Finally, we performed laparotomy, which showed that the small bowel was matted together by thick fibrous layers of adhesions. We performed adhesiolysis, and the patient was discharged home 3 weeks later. Histopathological findings of the fibrous layer were consistent with repair due to previous trauma and hemorrhage. We review the literature of this rare condition. (author)

    Jeffrey, R.B. Jr.; Federle, M.P.; Crass, R.A.

    1983-05-01

    In a review of over 300 CT scans of abdominal trauma, we encountered 13 patients with surgically proved pancreatic injuries. CT correctly diagnosed pancreatic fractures, contusions, or posttraumatic pseudocysts in 11 of these patients. There were two false positive and two false negative diagnoses. The CT diagnosis of pancreatic trauma may be difficult in selected patients who are scanned soon after injury. Acutely, the actual plane of a pancreatic fracture may be difficult to identify with CT, and the peripancreatic soft-tissue changes of traumatic pancreatitis are often subtle. Eight of 11 correctly diagnosed pancreatic injuries showed thickening of the left anterior renal fascia on CT scans. This sign should prompt a critical evaluation of the pancreas of the traumatized patient.

  17. Sonography of blunt abdominal trauma

    International Nuclear Information System (INIS)

    Sonographic examination of the abdomen after blunt abdominal trauma represents a rapid and effective diagnostic method without bothering the patient. It has proved its value not only in the confirmation or exclusion of free fluid in the abdomen caused by liver of spleen rupture, but also in such cases actually it replaces peritoneal lavage or exploratory laparotomy. It is also qualified for diagnosis of intraparenchymal or subcapsular hemorrhages, intraperitoneal as well as retroperitoneal and for follow up. In particualr delayed bleedings including the risk of a retarded organ rupture can be detected early. A failure rate of 1.4% in 282 sonographically examined cases of blunt abdominal trauma further confirms the reliability of this method. (orig.)

  1. Computer-aided recognition of emphysema on digital chest radiography

    International Nuclear Information System (INIS)

    Background: Computed tomography (CT) is the benchmark for diagnosis emphysema, but is costly and imparts a substantial radiation burden to the patient. Objective: To develop a computer-aided procedure that allows recognition of emphysema on digital chest radiography by using simple descriptors of the lung shape. The procedure was tested against CT. Methods: Patients (N = 225), who had undergone postero-anterior and lateral digital chest radiographs and CT for diagnostic purposes, were studied and divided in a derivation (N = 118) and in a validation sample (N = 107). CT images were scored for emphysema using the picture-grading method. Simple descriptors that measure the bending characteristics of the lung profile on chest radiography were automatically extracted from the derivation sample, and applied to train a neural network to assign a probability of emphysema between 0 and 1. The diagnostic performance of the procedure was described by the area under the receiver operating characteristic curve (AUC). Results: AUC was 0.985 (95% confidence interval, 0.965-0.998) in the derivation sample, and 0.975 (95% confidence interval, 0.936-0.998) in the validation sample. At a probability cutpoint of 0.55, the procedure yielded 92% sensitivity and 96% specificity in the derivation sample; 90% sensitivity and 97% specificity in the validation sample. False negatives on chest radiography had trace or mild emphysema on CT. Conclusions: The computer-aided procedure is simple and inexpensive, and permits quick recognition of emphysema on digital chest radiographs.

Soluble p-selectin(sP-selectin is crucial in modulating leukocyte adhesion to both platelets andendothelial cells during inflammatory response and thrombus formation. Wehypothesized that sP-selectin, an index of both platelet activation and acuteinflammation, rapidly increases and modulates the recruitment of circulatingwhite blood cells (WBC in patients following AMI.Methods: We conducted a prospective cohort study of 142 consecutive patients withST-segment elevated AMI of onset 0.10 in three intervals from the start of chest painto blood sample collection (< 180 min, ≥ 180 < 360, and ≥ 360 < 720 followingAMI. Correlation analysis demonstrated that the increase in the plasmalevel of sP-selectin was significantly related to the circulating WBCcount (r = 0.248, p = 0.003.Conclusions: sP-selectin was markedly elevated in an early phase of AMI. sP-selectin maybe involved in modulating the recruitment of circulating WBC during AMI.These findings raise the need for a prospective investigation of sP-selectin asa potential reliable clinical tool for rapidly diagnosing AMI.

We explored possible relationships between seismic intensity and the causes and types of injuries, and we assessed the ability of the Injury Severity Score, New Injury Severity Score, and Chest Injury Index to predict respiratory failure in chest injury patients. RESULTS: The incidence of chest injuries was 9.9% in the stronger Wenchuan earthquake and 22.2% in the less intensive Lushan earthquake. The most frequent cause of chest injuries in both earthquakes was being accidentally struck. Injuries due to falls were less prevalent in the stronger Wenchuan earthquake, while injuries due to burial were more prevalent. The distribution of types of chest injury did not vary significantly between the two earthquakes, with rib fractures and pulmonary contusions the most frequent types. Spinal and head injuries concurrent with chest injuries were more prevalent in the less violent Lushan earthquake. All three trauma scoring systems showed poor ability to predict respiratory failure in patients with earthquake-related chest injuries. CONCLUSIONS: Previous studies may have underestimated the incidence of chest injury in violent earthquakes. The distributions of types of chest injury did not differ between these two earthquakes of different seismic intensity. Earthquake severity and interval between rescue and treatment may influence the prevalence and types of injuries that co-occur with the chest injury. Trauma evaluation scores on their own are inadequate predictors of respiratory failure in patients with earthquake

  9. Chest Wall tumor: combined management

    International Nuclear Information System (INIS)

    Cancer is relatively rare disease among children and adolescents. The incidence of solid tumors other than CNS is less than 2/100,000. Tumors of the chest wall can arise either from the somatic tissue or ribs. These are rare, so either institutional reviews or multi institutional studies should determine optimal therapeutic management. Of the bony chest wall, Ewing's sarcoma or the family of tumor (peripheral neuro epithelioma, Askin tumor), are the most common. These lesions are lytic and have associated large extra pleural component. This large extra pleural component often necessitates major chest wall resection (3 or more ribs), and when lower ribs are involved, this entails resection of portion of diaphragm. Despite this resection, survival in the early 1970 was 10-20%. Since 1970 multi agent chemotherapy has increased survival rates. of importance, however, is these regimens have caused significant reduction of these extra pleural components so that major chest wall resections have become a rarity. With improved survival and decreased morbidity preoperative chemotherapy followed by surgery is now the accepted modality of treatment. Another major advantage of this regimen is that potential radiation therapy may be obviated. The most common chest wall lesion is rhabdomyosarcoma. In the IRS study of 1620 RMS patients, in 141 (9%) the primary lesion was in the chest wall. these are primarily alveolar histology. when lesions were superficial, wide local excision with supplemental radiation therapy was associated with low morbidity and good overall survival. however, a majority have significant intra- thoracic components. in these circumstances the resectability rate is less than 30% and the survival poor. Other lesions include non rhabdomyosarcomas, eosinophilic granuloma, chondrosarcoma, and osteomyelitis. The management of these lesions varies according to extent, histology, and patient characteristics

  11. Tuberculosis of the chest

    International Nuclear Information System (INIS)

    The relationship between tuberculosis and mankind has been known for many centuries, with the disease being one of the major causes of illness and death. During the early 1980s, there was a widespread belief that the disease was being controlled, but by the mid-1980s, the number of cases increased. This change in the epidemiological picture has several causes, of which the AIDS epidemic, the progression of poverty in developing countries, the increase in the number of elderly people with an altered immune status and the emergence of multidrug-resistant tuberculosis are the most important. Mainly due to this epidemiological change, the radiological patterns of the disease are also being altered, with the classical distinction between primary and postprimary disease fading and atypical presentations in groups with an altered immune response being increasingly reported. Therefore, the radiologist must be able not only to recognize the classical features of primary and postprimary tuberculosis but also to be familiar with the atypical patterns found in immuno-compromised and elderly patients, since an early diagnosis is generally associated with a greater therapeutic efficacy. Radiologists are, in this way, presented with a new challenge at the beginning of this millennium

    1996-03-01

    Over a two and a half year period, 25 patients presenting to the Glasgow Royal Infirmary underwent emergency thoracotomy for suspected severe chest injuries. Eighteen (72 per cent) were performed in the Accident and Emergency (A&E) department and seven (28 per cent) in a fully equipped operating theatre after resuscitation. There were 23 men and 2 women. Twenty-three (92 per cent) had been stabbed, one (4 per cent) had been shot and one (4 per cent) had sustained a blunt injury in a road traffic accident. Eight (32 per cent) patients survived. All survivors had been stabbed and seven were well enough to undergo thoracotomy in theatre. Only one (5.6 per cent) of the patients operated upon in the A&E department survived to discharge, although three (16.8 per cent) survived the initial procedure. Three of four patients survived, in whom the diagnosis of cardiac tamponade was initially missed. Thirteen (76.5 per cent) of the 17 who did not survive had no vital signs on admission. Outcomes may be improved if appropriately trained hospital staff are immediately available and prehospital delays are minimized so that patients arrive sooner with signs of life still present. Ambulance paramedic interventions have little to offer these patients and may worsen the prognosis if they result in delayed transport to hospital. The emphasis placed on diagnosis and treatment of cardiac tamponade in Advanced Trauma Life Support programmes is appropriate and all staff involved in these cases should undergo this type of training.

  13. Analysis of chest image performance in patients with acute chlorine poisoning

    International Nuclear Information System (INIS)

    Objective: To explore chest image features of patients with acute chlorine poisoning and their clinical values. Methods: A retrospective analysis was performed by chest image features of 117 patients with acute chlorine poisoning. All the patients were classified according to Chinese management of occupational acute chlorine poisoning diagnosis standard. Results: Sixty-five patients presented with stimulus response, and normal or both lungs had a little more white on their chest images. Thirty-one cases presented with minor poisoning, and without or the texture of both lungs was increased, and grew hazy and coarse.seventeen cases were moderate, and small sample vague shadows or single or multiple limitations lamellar shadow. Four cases were serious,and two lungs had extensive and density homogeneous consolidation shadow. Conclusions: It would make the diagnosis and assessment of chlorine poisoning more easier based on the combination of chest image features, the clear history of acute chlorine poisoning and relevant clinical performance.

    Full Text Available Fungal species are not frequently encountered in an immunocompetent host. Invasive aspergillosis typically occurs in severely immunocompromised patient. Aspergillus infection of breast and chest wall are rarely encountered in an immunocompetent as well as in immunocompromised host. Till date only 13 cases of fungal infection of breast and chest wall have been reported in the literature. This report presents a case of aspergillosis of bilateral breast and chest wall in an immunocompetent male, clinically mimicking breast cancer. Diagnosis was achieved by fine-needle aspiration cytology and subsequently Aspergillus flavus was identified on fungal culture. The patient was successfully treated with voriconazole. Prompt diagnosis by cytology and appropriate treatment is necessary to prevent adverse outcome. Here, we present this rare case of fungal infection of breast and chest wall with relevant review of the literature.

    International Nuclear Information System (INIS)

    Blunt trauma patients with myocardial ruptures rarely survive long enough to reach a trauma center; however, for the survivors, prompt diagnosis and surgery are mandatory and save up to 80% of patients. Preoperative diagnosis of myocardial ruptures is assessed by echocardiography or, more rarely, by echocardiography. We report two cases of blunt trauma patients with an atrial appendage rupture which could be retrospectively identified on admission CT survey. (orig.)

  16. Low-dose spiral CT: applicability to paediatric chest imaging

    International Nuclear Information System (INIS)

    Background. Spiral CT of the chest is an imaging technique with unequivocal indications and proven higher sensitivity and specificity than conventional chest X-rays. However, particularly in children, attempts should be made to reduce radiation exposure to a minimum. Objective. To evaluate whether a low-dose technique in spiral CT scanning results in adequate diagnostic information. Materials and methods. In a prospective study, 27 children (range 3 weeks to 14 years, mean 7 years) underwent a low-dose CT examination of the chest for various indications. The tube energy was 12.5 mAs (n = 5), 25 mAs (n = 17), 50 mAs (n = 3), or 75 mAs (n = 2) per slice. Two radiologists evaluated, in consensus, the CT scans with respect to their diagnostic value and comparison was made with 20 standard-dose chest CT examinations of adults (175 mAs per slice, mean age 56 years) with respect to technical image quality (noise and artefacts). In a second part of the study, dose measurements were carried out by means of exposing thermoluminescent dosimeters attached to a water/air phantom simulating a child's chest. Results. All low-dose CT scans were of diagnostic image quality and no additional studies were necessary. The average image noise was significantly higher than in standard-dose CT examinations (SD 39.5 compared with 12.5 for unenhanced soft tissue, P < 0.01), but did not hinder accurate diagnosis. Artefacts were exclusively due to patient motion. Radiation exposure per slice was approx. 4 mGy at 25 mAs and 34 mGy at 250 mAs, regardless of slice thickness. Conclusions. For all indications in paediatric CT scanning of the chest, low-dose technique provides adequate image quality without loss of diagnostic information. The radiation exposure is approximately 5-20 % of a standard-dose CT. (orig.)

    2015-10-01

    Blunt thoracic aortic injury (BTAI) remains a common cause of death following blunt mechanisms of trauma. Among patients who survive to reach hospital care, significant advances in diagnosis and treatment afford previously unattainable survival. The Society for Vascular Surgery (SVS) guidelines provide current best-evidence suggestions for treatment of BTAI. However, several key areas of controversy regarding optimal BTAI care remain. These include the refinement of selection criteria, timing for treatment and the need for long-term follow-up data. In addition, the advent of the Aortic Trauma Foundation (ATF) represents an important development in collaborative research in this field. PMID:25868973

  18. Added diagnostic benefit of 16-row whole-body spiral CT in patients with multiple trauma differentiated by region and injury severity according to the ATLS registered concept

    International Nuclear Information System (INIS)

    Purpose: to determine the added diagnostic benefit of using MS-CT in multiple trauma patients differentiated by severity of injury and affected body region. Materials and methods: a retrospective analysis was performed of the 16-row whole-body spiral CT findings in 275 multiple trauma patients (73% men, 27% women; age 39.6 ± 18.9 years) with regard to additional findings and new findings obtained with CT compared to the findings obtained by conventional projection radiography and abdominal ultrasound in the emergency room. The additional and new findings were differentiated by body region (head, face, chest, pelvis, abdomen, spine) and the degree of severity according to the three classes of injuries distinguished by the ATLS registered concept (class 1: simple injury, class 2: potentially life threatening, class 3: immediately life threatening). Results: a total of 921 additional findings (findings potentially relevant for further diagnosis and therapy in addition to the findings obtained by conventional radiography or ultrasound) were obtained by MS-CT in all patients. The distribution by number of patients and body region was as follows: 22 neck, 76 face, 125 chest, 112 abdomen, 50 pelvis, and 91 spine. Most additional findings were categorized as potentially life threatening (ATLS class 2). In addition, there were 439 completely new findings, involving the head in 128 patients (mostly ATLS class 3), the face in 18, the chest in 47, the abdomen in 26, and the spine in 9 patients. Most new findings involving the face, abdomen, and spine were ATLS class 2 injuries. (orig.)

  19. Thoracic trauma in newborn foals

    International Nuclear Information System (INIS)

    In a report describing life ending fractures (255 horses) from the Livestock Disease Diagnostic Center, Kentucky (1993 and 1994), 32 foals had rib fractures. The purpose of our study was to examine the incidence of rib fractures in newborn foals on a Thoroughbred studfarm by physical and radiographic examination, to determine factors which may contribute to the problem and to document any clinical consequences. All foals (263) included were examined within 3 days of birth. The thoracic cage was palpated externally for abnormalities and all foals were placed in dorsal recumbency to evaluate thoracic cage symmetry. Radiographs were used to diagnose foals with thoraciccage asymmetry (TCA) and rib fracture (RF). A diagnosis of costochondral dislocation (CD) was made when no radiographic evidence of fracture was present but there was severe TCA, Fifty-five foals (20.1%) had TCA (9 RF), One to 5 ribs were fractured on 9 of 40 radiographic studies. No consequences of the thoracic trauma was detected clinically, radiographically or ultrasonographically in this group of foals or at a 2- and 4-week follow-up examination. The percentage of foals with a history of abnormal parturition was higher in the TCA foals (15%) compared to the normal foals (6.8%). There weremore primiparous dams in the TCA group than in the normal foal group. Fillies (56.6%) had a higher incidence of birth trauma than colts (43.4%), Thisstudy demonstrates that thoracic trauma is often present in newborn foals and may not always be of clinical significance. Dystocia foals and foals from primiparous mares should be considered high risk for thoracic trauma

    Spinal trauma has a potential capability for catastrophic neurologic injury and physical injury. Spinal Trauma usually involved bony elements (vertebral spine), spinal cord, nerve roots, peripheral nerves and soft tissue. Early treatment should begun at the site of injury and during transportation to hospital. Protection to cervical spine and cervical spinal cord and patent respiration are the top priorities. There has been an established definitive procedures for the treatment of spinal trauma.

    Schneir, Aaron

    2001-07-01

    Full Text Available The purpose of this study was to describe the clinical findings in patients with splenic injury and to determine if isolated left lower chest injury may be the single clinical indicator of splenic injury. The medical records of all adult blunt trauma patients with splenic injury over a 14 month period were reviewed. Significant left lower chest injury was considered present if the patient had left sided pleuritic chest pain with tenderness to ribs 7-12 or if these ribs were visualized as fractured on any imaging study. Patients were considered to have clinical findings suggestive of splenic injury if they had pre-hospital or emergency department hypotension, abdominal pain or tenderness, a Glasgow coma scale < 15, or gross hematuria. Ninety patients had splenic injury. Thirty-nine (43%. 95% CI 33, 54% patients had significant left lower chest injury. In five (6%. 95% CI 2, 12% patients, injury to this portion of the chest was the single indicator of splenic injury. Nearly half the patients with splenic injury will have significant injury to the left lower chest and this finding may be the only indicator of splenic injury.

    Chest X-ray in newborns and infants shows great differences to that in adults. Therefore all radiologists, who engage in X-rays in this age group, must be familiar with the special features. At the beginning specific items of examination methods are explained, which must be strictly followed due to radiological protection. Focus of the paper is the discussion of the important chest diseases in newborn and infants, which are mostly unknown in chest diagnosis in adults. Many of them can be life-threatening, thus their knowledge is essential. Pathophysiological explanations shall make the special radiological signs understandable. (orig.)

    2014-01-01

    Background Equestrian sports are common outdoor activities that may carry a risk of liver injury. Due to the relative infrequency of equestrian accidents the injury patterns and outcomes associated with liver trauma in these patients have not been well characterized. Methods We examined our experience of the management of equestrian liver trauma in our regional hepatopancreaticobiliary unit at a tertiary referral center. The medical records of patients who sustained liver trauma secondary to equestrian activities were analysed for parameters such as demographic data, liver function tests, patterns of injury, radiological findings, the need for intervention and outcomes. Results 20 patients sustained liver trauma after falling from or being kicked by a horse. The majority of patients were haemodynamically stable on admission. Alanine transaminase (ALT) levels were elevated in all patients and right-sided rib fractures were a frequently associated finding. CT demonstrated laceration of the liver in 12 patients, contusion in 3 and subcapsular haematoma in 2. The right lobe of the liver was most commonly affected. Only two patients required laparotomy and liver resection; the remaining 18 were successfully managed conservatively. Conclusions The risk of liver injury following a horse kick or falling off a horse should not be overlooked. Early CT imaging is advised in these patients, particularly in the presence of high ALT levels and concomitant chest injuries such as rib fractures. Despite significant liver trauma, conservative management in the form of close observation, ideally in a high-dependency setting, is often sufficient. Laparotomy is only rarely warranted and associated with a significantly higher risk of post-operative bile leaks. PMID:25177363

  8. Possibilities for exposure reduction in computed tomography examination of acute chest pain

    International Nuclear Information System (INIS)

    Electrocardiogram-gated (ECG) computed tomography (CT) investigations can be accompanied by high amounts of radiation exposure. This is particularly true for the investigation of patients with unclear and acute chest pain. The common approach in patients with acute chest pain is standard spiral CT of the chest. The chest pain or triple-rule-out CT protocol is a relatively new ECG-gated protocol of the entire chest. This article reviews and discusses different techniques for the CT investigation of patients with acute chest pain. By applying the appropriate scan technique, the radiation exposure for an ECG-gated protocol must not necessarily be higher than a standard chest CT scan Aortic pathologies are far better depicted by ECG-gated scan protocols and depending on the heart rate coronary artery disease can also be detected at the same time. The use of ECG-triggered scans will not support the diagnostics of the pulmonary arteries. However, in unspecific chest pain an ECG-triggered scan protocol can provide information on the differential diagnosis. (orig.)

    2010-06-01

    The temporal bones are paired structures located on the lateral aspects of the skull and contribute to the skull base. Trauma is usually the result of blunt head injury and can result in damage to the brain and meninges, the middle and internal ear, and the facial nerve. Complications can include intracranial hemorrhage, cerebral contusion, CSF leak and meningitis, hearing loss, vertigo, and facial paralysis. To prevent these complications, diagnosis followed by appropriate medical and surgical management is critical. Diagnosis relies primarily on physical signs and symptoms as well as radiographic imaging. Emergent intervention is required in situations involving herniation of the brain into the middle ear cavity or hemorrhage of the intratemporal carotid artery. Patients with declining facial nerve function are candidates for early surgical intervention. Conductive hearing loss can be corrected surgically as an elective procedure, while sensorineural hearing loss carries a poor prognosis, regardless of management approach. Children generally recover from temporal bone trauma with fewer complications than adults and experience a markedly lower incidence of facial nerve paralysis. PMID:22110824

    Reconstruction of the chest wall after balistic or other trauma requires good and muscle cover and creation of a new, stable and airtight wall. The authors present a case of balistic trauma of the right anterolateral chest wall which was urgently debrided and subsequently reconstructed by sandwich combination of a latissimus dorsi muscle flap and synthetic material composed of a sheet of PTFE and creation of two methylmethylacrylate ribs. The advantage of this technique is that it avoids the use of autologous tissue from an already weakened chest wall and confers a new chest stability in several sites corresponding to the wall defect with easily available and easy-to-use materials.

    A major difficulty with chest radiographic analysis is the invisibility of abnormalities caused by the superimposition of normal anatomical structures, such as ribs, over the main tissue to be examined. Suppressing the ribs with no information loss about the original tissue would therefore be helpful during manual identification or computer-aided detection of nodules on a chest radiographic image. In this study, we introduce a two-step algorithm for eliminating rib shadows in chest radiographic images. The algorithm first delineates the ribs using a novel hybrid self-template approach and then suppresses these delineated ribs using an unsupervised regression model that takes into account the change in proximal thickness (depth) of bone in the vertical axis. The performance of the system is evaluated using a benchmark set of real chest radiographic images. The experimental results determine that proposed method for rib delineation can provide higher accuracy than existing methods. The knowledge of rib delineation can remarkably improve the nodule detection performance of a current computer-aided diagnosis (CAD) system. It is also shown that the rib suppression algorithm can increase the nodule visibility by eliminating rib shadows while mostly preserving the nodule intensity. PMID:26775736

  13. Chest wall tuberculosis; CT findings in 14 patients

    International Nuclear Information System (INIS)

    To present CT findings of chest wall tuberculosis. CT scans were obtained in 14 patients with proven chest wall tuberculosis. Diagnosis was confirmed by means of right open thoracostomy with abscess evacuation (n=1), excision and curettage (n=11) or excision and curettage along with resection of the involved lung (n=2). The images were assessed with emphasis for the extrapleural, pleural, and pulmonary lesions. All patients showed juxtacostal soft tissue mass with central low attenuation and peripheral rim enhancement. The lesions were located in the left hemithorax in eight patients and in the right in six. Multiple lesions were found in three patients (two in one and three in two). Rib destruction was observed in four patients. Intercostal muscle involvement of thickening and enhancement were shown in all patients. Thirteen patients (93%) had evidence of pulmonary tuberculosis: active pulmonary tuberculosis in nine and stable tuberculosis in four. Pleural lesions, including empyema necessitatis in six, were observed in eleven (79%). On CT scan, chest wall tuberculosis is characterized by juxtacostal soft tissue lesion with central low attenuation and peripheral rim enhancement. Rib destruction may be associated. Additionally, enhancing intercostal muscle suggest direct inflammatory process of tuberculosis and spread channel to the chest wall involvement of pleuropulmonary tuberculosis

    Mesenteric trauma, i.e., injuries located in the bowel or organs supplied by the superior mesenteric artery, can be life-threatening. The incidence of these lesions is low. Most occur as result of blunt and penetrating abdominal trauma due mainly to gunshot wounds or road accidents. Management of these serious injuries can be challenging in the military field hospitals. The major problem in austere environment is the unavailabiity of computerized axial and other tools gene rally used for diagnosis. As an alternative to tomography diagnostic peritoneal lavage can be used with a high sensitivity for the detection of mesenteric trauma. The second difficulty is technical. General surgeons without vasular training or supplies must prepared to suspect and reonstuct lesions of the superior mesenteric available resources. PMID:16775948

    The suggestion that thoracic shape of anteroposterior radiographs reflects lung compliance was examined in 62 preterm newborn infants (none with pulmonary hypoplasia) by measuring ratios of upper to lower chest widths. Chest shape did not vary significantly with the presence of respiratory distress syndrome (RDS) or with gender, Apgar score, endotracheal intubation, radiographic severity of RDS, or age at radiography. However, decreased maturity was associated with a relatively wide upper chest and narrow lower chest. Developmental factors may be more important than lung compliance (and the other factors noted) in determining the radiographic configuration of the infantile chest

    Radiologic manifestations of occupational lung disease are summarized and classified in this book according to the ILO system. The interpretation of chest roentgenograms outlines the progression of each disease and is accompanied with clinically-oriented explanations. Some of the specific diseases covered include asbestosis, coal worker's pneumoconiosis, silicosis, non-mining inhalation of silica and silicates, beryllium induced disease, inhalation of organics and metallics, and occupationally induced asthma

  19. Gastric tumors on chest radiographs

    International Nuclear Information System (INIS)

    Gastric neoplasms of three patients protruded into their gas-containing fornices and were first visualized on plain chest radiographs. Endoscopy and/or surgery confirmed these to be a polyp, a leiomyoma, and an adenocarcinoma. The polyp, 1.3 cm in diameter, was the smallest of these three, but smaller lesions may be detectable under suitable conditions. Adequate technique and positioning, sufficiently large lesions in the upper portion of the stomach, a central beam tangential to the tumor, sufficient gas in the stomach, and careful scrutiny by the observer are required. Lesions may be more readily visualized during chest radiography when oral sodium bicarbonate is used to distend the stomach. In chest radiography, exposure limited to the lung fields has been advocated for economy and dose reduction. However, too small an exposure field may result in loss of information potentially beneficial to the patient. Using the smaller of two popular film sizes (35 x 43 cm and 35 x 35 cm), the saving in surface and bone marrow doses is negligible, and the saving in gonad dose may be nil over that when shielding is used. The interest of the observer may be absorbed by a concomitant cardiac or pulmonary lesion. Careful scrutiny of the entire radiograph is therefore essential. (author)

    2007-07-01

    Full Text Available Acute limb compartment syndrome (LCS is a limb-threatening and occasionally life-threatening condition caused by bleeding or edema in a closed muscle compartment surrounded by fascia and bone, which leads to muscle and nerve ischemia. Well-known causative factors are acute trauma and reperfusion after treatment for acute arterial obstruction. Untreated compartment syndrome usually leads to muscle necrosis, limb amputation, and, if severe, in large compartments, renal failure and death. Alertness, clinical suspicion of the possibility of LCS, and occasionally intracompartmental pressure (ICP measurement are required to avoid a delay in diagnosis or missed diagnosis. Open fasciotomy, by incising both skin and fascia, is the most reliable method for adequate compartment decompression. The techniques of measuring ICP have advantages and disadvantages, whereas the pressure level that mandates fasciotomy is controversial. Increased awareness of the syndrome and the advent of measurements of ICP pressure have raised the possibility of early diagnosis and treatment. This presentation reports LCS, including etiology, diagnosis, ICP measurement, management, and outcome.

  4. A study of diagnostic imaging in pancreatic trauma

    International Nuclear Information System (INIS)

    Pancreatic trauma treatment depends on pancreatic ductal injury. We examined the usefulness and problems of diagnostic imaging, such as enhanced CT, ERP, and CT after ERP, in pancreatic trauma. Subjects were 12 patients with pancreatic trauma treated in our hospital between April 1993 and March 2000. Enhanced CT was performed in 6 patients undergoing diagnostic imagings and ERP in 4 of the 6. Overall diagnostic accuracy of pancreatic ductal injury in enhanced CT was 16.7% and accuracy in ERP with CT after ERP was 100%. Intraoperative diagnosis of main pancreatic ductal injury was difficult in 1 of 2 patients in whom ERP failed. The importance of preoperative diagnostic imaging is thus clear. We expect that MRCP, recently evaluated in pancreatic disease diagnosis, will become a new pancreatic trauma modality. (author)

    International Nuclear Information System (INIS)

    A 21-year-old man presented with pleuritic substernal chest pain of one hour's duration. The pain was exacerbated in a supine position and did not radiate. Questioning revealed that he was a recreational user of cocaine and had inhaled free-based cocaine via a pipe the previous evening and as recently as two hours before admission to the hospital. Physical examination demonstrated an anxious young man with a respiratory rate of 26 breaths per minute and shallow. He was afebrile with normal heart rate and blood pressure. His sternum was tender to palpation, and auscultation revealed precordial crepitus synchronous with systole. His electrocardiogram showed sinus rhythm at a rate of 62 beats per minute. Posteroanterior and lateral roentgenograms of the chest were obtained. A diagnosis of spontaneous pneumomediastinum was made

    This paper reports on neumothoraces that are clinically important abnormalities that usually appear as a subtle, fine line pattern on chest radiographs. We are developing a computer vision system for automated detection of pneumothorax to aid radiologists diagnosis. Chest images were digitized with a 0.175-mm pixel size, yielding a 2,000 x 2,430 matrix size, and 10 bits of gray scale. After indentification of the lung regions, an edge detection filter was employed in the apical areas to enhance a pneumothorax pattern. Ribs were detected with a technique based on statistical analysis of edge gradients and their orientations. Points located on a curved line suggestive of a pneumothorax in this enhanced image were detected with a Hough transform

  7. The coagulopathy of trauma.

    Maegele, M

    2014-04-01

    Trauma is a leading cause of death, with uncontrolled hemorrhage and exsanguination being the primary causes of preventable deaths during the first 24 h following trauma. Death usually occurs quickly, typically within the first 6 h after injury. One out of four patients arriving at the Emergency Department after trauma is already in hemodynamic and hemostatic depletion. This early manifestation of hemostatic depletion is referred to as the coagulopathy of trauma, which may distinguished as: (i) acute traumatic coagulopathy (ATC) and (ii) iatrogenic coagulopathy (IC). The principle drivers of ATC have been characterized by tissue trauma, inflammation, hypoperfusion/shock, and the acute activation of the neurohumoral system. Hypoperfusion leads to an activation of protein C with cleavage of activated factors V and VIII and the inhibition of plasminogen activator inhibitor-1 (PAI-1), with subsequent fibrinolysis. Endothelial damage and activation results in Weibel-Palade body degradation and glycocalyx shedding associated with autoheparinization. In contrast, there is an IC which occurs secondary to uncritical volume therapy, leading to acidosis, hypothermia, and hemodilution. This coagulopathy may, then, be an integral part of the "vicious cycle" when combined with acidosis and hypothermia. The awareness of the specific pathophysiology and of the principle drivers underlying the coagulopathy of trauma by the treating physician is paramount. It has been shown that early recognition prompted by appropriate and aggressive management can correct coagulopathy, control bleeding, reduce blood product use, and improve outcome in severely injured patients. This paper summarizes: (i) the current concepts of the pathogenesis of the coagulopathy of trauma, including ATC and IC, (ii) the current strategies available for the early identification of patients at risk for coagulopathy and ongoing life-threatening hemorrhage after trauma, and (iii) the current and updated European

    Orthodontic therapy has a big role in the treatment and prevention of malpositions. The signs and symptoms experienced by patients with occlusal trauma are mobility of teeth, temperomandibular joint pain, pain on mastication and periodontal disease. Early diagnosis, proper treatment plan and correction of malocclusion can lead to a successful outcome. Lack of awareness of orthodontic treatment in patients with occlusal trauma can even lead to loss of tooth structure.

    International Nuclear Information System (INIS)

    Simple abdomen film has played an important role in decision of emergency operations in patients with the abdominal trauma. Nowadays, it still acts as a primary and inevitable processes in emergency condition. At the Department of Radiology, Hanil Hospital, 70 patients, who were laparotomied due to penetrating or nonpernetraing abdominal trauma, were observed and analyzed with simple abdomen film after comparison with the operative findings. The results are as follows: 1. Most frequent age distribution was 10 to 39 years and marked 70%. Male was in 90% incidence. 2. Penetrating injury largely involved the small bowel and abdominal wall. Non-penetrating injury usually involved the spleen, small bowel, liver, kidney, pancreas, duodenum. 3. Single organ injury occurred in higher incidence at the small bowel and abdominal wall. Multiple organ injury occurred in higher incidence at the spleen, liver, kidney and pancreas. 4. Organ distribution was 26% in spleen, 22% in small bowel, 14% in liver, 11% in abdominal wall. 7% in pancreas, 7% in kidney. 5% in duodenum, 4% in GB and CBD, 2% in diaphragm, 2% in colon, and 1% in stomach. 5. The specific roentgen findings and their frequency which useful in differential diagnosis at abdominal trauma, were as follows: a) flank fluid; Detectable possibility was 71% in liver laceration, 69% in spleen laceration and 57% in pancreas laceration. b) ipsilateral psoas shadow obliteration; Detectable possibility was 57% in liver laceration, 57% in kidney laceration and 46% in spleen laceration. c) free air; Detactable possibility was 60% in duodenal perforation, and 36% in peroration of upper part of small bowel. d) Reflex ileus; Detectable possibility was 64% in small bowel, 50% in liver laceration and 35% in spleen laceration. e) rib fracture; Detactable possibility was 36% in liver laceration and 23% in spleen laceration. f) pleural effusion; Detectable possibility was 29% in liver laceration and 27% in spleen laceration

    2013-05-01

    Chronic chest pain can arise from a variety of etiologies. However, of those potential causes, the most life-threatening include cardiac disease. Chronic cardiac chest pain may be caused either by ischemia or atherosclerotic coronary artery disease or by other cardiac-related etiologies, such as pericardial disease. To consider in patients, especially those who are at low risk for coronary artery disease, are etiologies of chronic noncardiac chest pain. Noncardiac chest pain is most commonly related to gastroesophageal reflux disease or other esophageal diseases. Alternatively, it may be related to costochondritis, arthritic or degenerative diseases, old trauma, primary or metastatic tumors, or pleural disease. Rarely, noncardiac chest pain may be referred pain from organ systems below the diaphragm, such as the gallbladder. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. PMID:23542027

Em alguns países, o trauma do idoso responde por uma elevada taxa de mortalidade, a qual se apresenta de forma desproporcionalmente maior do que a observada entre a população de adultos jovens. Tal fato acarreta um grande consumo de recursos financeiros destinados à assistência da saúde e um elevado custo social. As características fisiológicas próprias do idoso, assim como a presença freqüente de doenças associadas, faz com que estes pacientes se comportem diferentemente e de forma mais complexa do que os demais grupos etários. Estas particularidades fazem com que o atendimento ao idoso vítima de trauma se faça de forma diferenciada. A presente revisão aborda aspectos da epidemiologia, da prevenção, da fisiologia, do atendimento e da reabilitação do idoso vítima de trauma.The populational growth of the elderly, associated to a healthier and more active life, make this group of people more exposed to accidents. In some countries, trauma in the elderly is responsible for a high mortality rate, desproportionately higher than in the adults.

The distinct physiologic characteristics of the elderly and the frequent presence of associated diseases make that these patients behave diferently and in a more complex way than patients of other ages. These particularities make that health care to the elderly victims of trauma have to be different. The present revision is about aspects of epidemiology, prevention, physiology, health care and reabilitation of the elderly victims of trauma.

    Eighty-six [67Ga]citrate chest scans were performed in 71 adult patients with the acquired immunodeficiency syndrome. Forty-five of these patients also had Kaposi's sarcoma. Only 29 of 57 abnormal scans were correlated with abnormal chest radiographs. Chest radiographs were negative for 27 scans and unavailable for one. Several scan patterns were seen. Diffusely increased lung uptake was seen most commonly with Pneumocystis carinii pneumonia, but also other infections and noninfectious inflammatory conditions. Focal uptake corresponding to regional lymph node groups occurred most often with Mycobacterium avium-intracellulare but aslo with lymphoma. Localized intrapulmonary uptake was seen in bacterial pneumonias. Perihilar activity occurred in two cases. When chest radiographs were abnormal and 67Ga scans negative, the most common diagnosis was pulmonary Kaposi's sarcoma

    Acute coagulopathy of trauma predicts a poor clinical outcome. Tissue trauma activates the sympathoadrenal system resulting in high circulating levels of catecholamines that influence hemostasis dose-dependently through immediate effects on the two major compartments of hemostasis, i.......e., the circulating blood and the vascular endothelium. There appears to be a dose-dependency with regards to injury severity and the hemostatic response to trauma evaluated in whole blood by viscoelastic assays like thrombelastography (TEG), changing from normal to hypercoagulable, to hypocoagulable and finally......, is an evolutionary developed response that counterbalances the injury and catecholamine induced endothelial activation and damage. Given this, the rise in circulating catecholamines in trauma patients may favor a switch from hyper- to hypocoagulability in the blood to keep the progressively more procoagulant...

    1987-11-01

    The impact of traumatic injuries on modern society in terms of morbidity, mortality, and economic cost is enormous. Studies have shown that both advanced life support skills and rapid stabilization and transport of the trauma victim have a beneficial effect on the patient's ultimate outcome. The Basic Trauma Life Support (BTLS) course was designed to provide pre-hospital care providers with the skills necessary to provide a thorough assessment, initial resuscitation, and rapid transportation of the trauma victim. Early studies suggest that the material is easily learned by prehospital care providers and that the on-scene time for trauma cases is reduced following training in BTLS. More widespread training in BTLS may have a significant effect on the mortality and morbidity associated with traumatic injuries. PMID:3662184

    Soon after it became available for clinical use, cranial CT became the method of choice for evaluating head trauma. Only relatively recently have newer generation full-body scanners been installed at major trauma centers, but experience is rapidly being gained in the utilization of CT for abdominal trauma. CT has proved highly accurate in diagnosing a wide variety of injuries to both intra- and retroperitoneal organs in pediatric and adult patient populations. The impact has been evident not only in decreasing utilization of other diagnostic tests, such as angiography, but also in practical management decisions, such as whether to perform exploratory laparotomy.

  14. Nodule detection by CT screening of chest

    International Nuclear Information System (INIS)

    Lung cancer screening using helical computed tomography (CT) has been carried out at the ''Anti-lung cancer association, Tokyo'' since 1993. We found 43 lung cancer cases (0.163%) during the 18-year period before introducing helical CT, but 76 lung cancer cases (0.436%) in 11 years after introducing helical CT. Among the cases detected in the screening period using helical CT, 74% were in stage IA, and the average size of the primary tumors was 17.3 mm. These data were better than in the screening period without helical CT. Of the 76 lung cancer cases detected after the introduction of helical CT, 19 cases (25%) were visible chest X-ray films, but 70 cases (92%) were visible on CT. We had 52 cases detected on repeated CT screenings, 41 cases (79%) of these cases were retrospectively found to have had a primary tumor overlooked previous CT screening images. In this seminar, former CT screening images of lung cancer cases were presented and we discussed how to improve earlier diagnosis. (author)

    Trauma patients are a diverse population with heterogeneous needs for ventilatory support. This requirement depends mainly on the severity of their ventilatory dysfunction, degree of deterioration in gaseous exchange, any associated injuries, and the individual feasibility of potentially using a noninvasive ventilation approach. Noninvasive ventilation may reduce the need to intubate patients with trauma-related hypoxemia. It is well-known that these patients are at increased risk to develop hypoxemic respiratory failure which may or may not be associated with hypercapnia. Hypoxemia in these patients is due to ventilation perfusion mismatching and right to left shunt because of lung contusion, atelectasis, an inability to clear secretions as well as pneumothorax and/or hemothorax, all of which are common in trauma patients. Noninvasive ventilation has been tried in these patients in order to avoid the complications related to endotracheal intubation, mainly ventilator-associated pneumonia. The potential usefulness of noninvasive ventilation in the ventilatory management of trauma patients, though reported in various studies, has not been sufficiently investigated on a large scale. According to the British Thoracic Society guidelines, the indications and efficacy of noninvasive ventilation treatment in respiratory distress induced by trauma have thus far been inconsistent and merely received a low grade recommendation. In this review paper, we analyse and compare the results of various studies in which noninvasive ventilation was applied and discuss the role and efficacy of this ventilator modality in trauma.

    Blunt trauma to pancreas is uncommon and clinical features are often non-specific and unreliable leading to possible delays in diagnosis and therefore increased morbidity. CT has been established as the imaging modality of choice for the diagnosis of abdominal solid-organ injury in the blunt trauma patient. The introduction of multidetector-row CT allows for high resolution scans and multiplanar reformations that improve diagnosis. Detection of pancreatic injuries on CT requires knowledge of the subtle changes produced by pancreatic injury. The CT appearance of pancreatic injury ranges from a normal initial appearance of the pancreas to active pancreatic bleeding. Knowledge of CT signs of pancreatic trauma and a high index of suspicion is required in diagnosing pancreatic injury.

    Histiocytic disorders of the chest comprise a broad spectrum of diseases. The lungs may be involved in isolation or as part of systemic disease. Some of these disorders are primary and have unknown etiology, and others result from a histiocytic response to a known cause. Among primary histiocytic disorders, pulmonary Langerhans cell histiocytosis (PLCH) is the most common; others include Erdheim-Chester disease and Rosai-Dorfman disease. Adult PLCH occurs almost exclusively in adults aged 20-40 years who smoke. Pediatric PLCH is extremely rare and typically occurs as part of multisystemic disease. Erdheim-Chester disease affects middle-aged and older adults; thoracic involvement usually occurs as part of systemic disease. Rosai-Dorfman disease affects children and young adults and manifests as painless cervical lymphadenopathy. Examples of secondary histiocytic disorders are storage diseases such as Gaucher disease, Niemann-Pick disease, and Fabry disease; pneumoconiosis such as silicosis and coal workers' pneumoconiosis; and infections such as Whipple disease and malakoplakia. These disorders are characterized at histopathologic examination on the basis of infiltration of alveoli or the pulmonary interstitium by histiocytes, which are a group of cells that includes macrophages and dendritic cells. Dendritic cells are a heterogeneous group of nonphagocytic antigen-presenting immune cells. Immunohistochemical markers help to distinguish among various primary histiocytic disorders. Characteristic radiologic findings in the appropriate clinical context may obviate biopsy to establish a correct diagnosis. However, in the absence of these findings, integration of clinical, pathologic, and radiologic features is required to establish a diagnosis. PMID:25763722

  20. Herpes simplex virus 1 pneumonia: conventional chest radiograph pattern

    International Nuclear Information System (INIS)

    The aim of this study was to describe the findings on plain chest radiographs in patients with herpes simplex virus pneumonia (HSVP). The study was based on 17 patients who at a retrospective search have been found to have a monoinfection with herpes simplex virus. The diagnosis was established by isolation of the virus from material obtained during fiberoptic bronchoscopy (FOB) which also included broncho-alveolar lavage and tissue sampling. Fourteen patients had a chest radiograph performed within 24 h of the date of the FOB. Two radiographs showed no abnormalities of the lung parenchyma. The radiographs of the other 12 patients showed lung opacification, predominantly lobar or more extensive and always bilateral. Most patients presented with a mixed airspace and interstitial pattern of opacities, but 11 of 14 showed at least an airspace consolidation. Lobar, segmental, or subsegmental atelectasis was present in 7 patients, and unilateral or bilateral pleural effusion in 8 patients, but only in 1 patient was it a large amount. In contradiction to the literature which reports a high correlation between HSVP and acute respiratory distress syndrome (ARDS), 11 of 14 patients did not meet the pathophysiological criteria for ARDS. The radiologist may suggest the diagnosis of HSVP when bilateral airspace consolidation or mixed opacities appear in a susceptible group of patients who are not thought to have ARDS or pulmonary edema. The definite diagnosis of HSV pneumonia can be established only on the basis of culture of material obtained by broncho-alveolar lavage. (orig.)

    2007-11-01

    Full Text Available Abstract The granulomatous inflammation of tuberculosis usually involves the lungs and the hilar lymph nodes. Musculoskeletal tuberculosis (TB occurs in 1–3% of patients with TB, while TB of the chest wall constitutes 1% to 5% of all cases of musculoskeletal TB. Furthermore, nowadays it is rarer to find extrapulmonary TB in immunocompetent rather that non-immunocompetent patients. The present case reports a fifty-six-year-old immunocompetent man with an anterior chest wall tuberculous abscess. The rarity of the present case relates both to the localization of the tuberculous abscess, and to the fact that the patient was immunocompetent. The diagnosis of musculoskeletal tuberculous infection remains a challenge for clinicians and requires a high index of suspicion. The combination of indolent onset of symptoms, positive tuberculin skin test, and compatible radiographic findings, strongly suggests the diagnosis. TB, however, must be confirmed by positive culture or histologic proof. Prompt diagnosis and treatment are important to prevent serious bone and joint destruction.

  2. Structured diagnostic imaging in patients with multiple trauma

    International Nuclear Information System (INIS)

    Purpose. Development of a concept for structured diagnostic imaging in patients with multiple trauma.Material and methods. Evaluation of data from a prospective trial with over 2400 documented patients with multiple trauma. All diagnostic and therapeutic steps, primary and secondary death and the 90 days lethality were documented.Structured diagnostic imaging of multiple injured patients requires the integration of an experienced radiologist in an interdisciplinary trauma team consisting of anesthesia, radiology and trauma surgery. Radiology itself deserves standardized concepts for equipment, personnel and logistics to perform diagnostic imaging for a 24-h-coverage with constant quality.Results. This paper describes criteria for initiation of a shock room or emergency room treatment, strategies for documentation and interdisciplinary algorithms for the early clinical care coordinating diagnostic imaging and therapeutic procedures following standardized guidelines. Diagnostic imaging consists of basic diagnosis, radiological ABC-rule, radiological follow-up and structured organ diagnosis using CT. Radiological trauma scoring allows improved quality control of diagnosis and therapy of multiple injured patients.Conclusion. Structured diagnostic imaging of multiple injured patients leads to a standardization of diagnosis and therapy and ensures constant process quality. (orig.)

    2013-01-01

    Full Text Available Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13% following blunt injury and 20 (87% after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury.

  4. Novel Influenza A (H1N1) Virus Infection in Children: Chest Radiographic and CT Evaluation

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the chest radiographic and CT findings of novel influenza A (H1N1) virus infection in children, the population that is more vulnerable to respiratory infection than adults. The study population comprised 410 children who were diagnosed with an H1N1 infection from August 24, 2009 to November 11, 2009 and underwent chest radiography at Dankook University Hospital in Korea. Six of these patients also underwent chest CT. The initial chest radiographs were classified as normal or abnormal. The abnormal chest radiographs and high resolution CT scans were assessed for the pattern and distribution of parenchymal lesions, and the presence of complications such as atelectasis, pleural effusion, and pneumomediastinum. The initial chest radiograph was normal in 384 of 410 (94%) patients and abnormal in 26 of 410 (6%) patients. Parenchymal abnormalities seen on the initial chest radiographs included prominent peribronchial marking (25 of 26, 96%), consolidation (22 of 26, 85%), and ground-glass opacities without consolidation (2 of 26, 8%). The involvement was usually bilateral (19 of 26, 73%) with the lower lung zone predominance (22 of 26, 85%). Atelectasis was observed in 12 (46%) and pleural effusion in 11 (42%) patients. CT (n = 6) scans showed peribronchovascular interstitial thickening (n = 6), ground-glass opacities (n = 5), centrilobular nodules (n = 4), consolidation (n = 3), mediastinal lymph node enlargement (n = 5), pleural effusion (n = 3), and pneumomediastinum (n = 3). Abnormal chest radiographs were uncommon in children with a swine-origin influenza A (H1N1) virus (S-OIV) infection. In children, H1N1 virus infection can be included in the differential diagnosis, when chest radiographs and CT scans show prominent peribronchial markings and ill-defined patchy consolidation with mediastinal lymph node enlargement, pleural effusion and pneumomediastinum

    Pneumothorax is usually diagnosed when signs of life-threatening tension pneumothorax develop. The case report describes novel data derived from miniature superficial sensors that continuously monitored the amplitude and symmetry of the chest wall tidal displacement (TDi) in a premature infant that suffered from pneumothorax. Off-line analysis of the TDi revealed slowly progressing asymmetric ventilation that could be detected 38 min before the diagnosis was made. The TDi provides novel and valuable information that can assist in early detection and decision making. PMID:26814803

The sex risk ratio was 3.1 for a principal diagnosis and 2.1 for a secondary diagnosis. The main causes of eye trauma were traffic accident, work accident, assault (among males <60 years of age, and falls (among elderly men and women. The proportion admitted to an ophthalmic department among those with a principal diagnosis of eye trauma (64.8% was significantly higher than among those with a secondary diagnosis (2.3% (p<.0001. Patients with a principal diagnosis of eye trauma had shorter hospital stays (7.1±10.2 days and lower fatality (0.07% than those with a secondary diagnosis of eye trauma (10.0±31.6 days and 0.3%, respectively.Data only from ophthalmic admissions tends to underestimate the true incidence rate of hospitalized eye trauma.

    To describe the patterns of ocular trauma, cause of injury and its effects on eye. A retrospective case series. Medical records of 1105 patients admitted with ocular trauma were reviewed. The details of patients regarding age, gender, literacy, cause of injury and its effects on eye were entered into specially-designed performa. Sample selection consisted of all patients with history of ocular trauma and who were admitted to hospital. Population details consisted patients who were referred to the hospital from all parts of N.W.F.P. Thus, the frequency of trauma in the hospital admissions was analysed. Ophthalmic trauma comprised 6.78% of the hospital admission. One thousand one hundred and five patients presented with eye injuries. Out of them, 21 patients suffered from trauma to both eyes. Almost 80% patients were male and 69% patients were below 30 years of age. Delayed presentation was more common and 63.61% patients presented after one week. Open globe injuries were more common (520 eyes (46.18%)) than closed globe injuries (484 eyes (42.98%)). 23.26% of open globe injuries were associated with intraocular and intra-orbital foreign bodies. Superficial non-perforating, eyelid and adnexal and burns were seen in 122 eyes (10.83%). Among the complications, lens damage and hyphema was seen in more than 50% of the patients, 16.60% eyes were infected at the time of admission and 4.88% of eyes needed enucleation or evisceration. The common causes of injury were violence in 37.37%, occupational in 24.43% and domestic accidents in 19.18%. Ophthalmic trauma is a major public health problem. Majority of the involved are male and under 30 years of age. Delayed presentation is more common. Open globe injuries are more frequent. Violence and occupational injuries are the major causes.

    The diagnosis of the traumatized spine is one of the key issues for trauma radiologists. The cross-sectional imaging procedures, computed tomography (CT) and magnetic resonance imaging (MRI) are the essential methods in spinal trauma radiology. These modalities are of great help in accurately assessing injury patterns and extent and in providing indications of patient outcome. In contrast to cross-sectional imaging, radiography has a role in the evaluation of minor spinal trauma only. It is generally accepted that trauma radiologists do not use typical classifications to evaluate the spine partly because such an ideal classification system does not yet exist. Not least because of this classification difficulty, eponyms and synonyms are widely used to describe traumatology of the spine as a high level of specific information is included in these various terms. The members of the trauma team should be aware of the strengths and limitations of the methods used in the assessment of the spine. This article provides a brief outline of fundamental knowledge about the diagnosis of spinal trauma. (orig.) [German] Die Beurteilung der verletzten Wirbelsaeule nimmt fuer Traumaradiologen eine zentrale Stellung ein. Die Schnittbildverfahren CT und MRT sind ihre wesentlichen Arbeitsmethoden.

  11. Imaging of chest disease due to intravenous heroin abuse

    International Nuclear Information System (INIS)

    Objective: To study the imaging findings of the chest disease due to intravenous heroin abuse. Methods: Twenty-five cases of clinically confirmed chest disease due to intravenous heroin abuse were retrospectively analyzed. 25 cases had conventional X-ray film, 6 cases had CT scanning, and 6 cases had echocardiography scanning. Results: On X-ray and CT, the following signs were found: lung making manifold (n = 5), small patchy shadow (n = 15), pneumatocele (n = 16), small cavity (n = 16), small node (n = 7), pleural effusion (n = 8 ), pneumothorax (n = 2), hydropneumothorax (n = 6), pulmonary edema (n = 2), megacardia (n = 11), multiple-shaped lesion (n = 20). On echocardiography, tricuspid vegetation (n = 4) and tricuspid insufficiency (n = 4) were found. Conclusion: The X-ray and CT manifestations of chest inflammation due to intravenous heroin abuse are multiple. The multiple small cavities and pneumatoceles sign are of some value in the diagnosis of lung inflammation due to intravenous heroin abuse among young patients

  12. Value of the lateral chest radiograph in tuberculosis in children

    International Nuclear Information System (INIS)

    The value of the lateral chest radiograph, often considered a useful adjunct in the detection of hilar adenopathy, was evaluated in a prospective study of 449 children assessed for tuberculosis. Of these children 298 presented to the hospital with signs and symptoms suggestive of tuberculosis, while 151 were investigated in a regional clinic solely because they were in close contact with an adult household member on treatment for tuberculosis. Tuberculosis was confirmed by culture in 176 of the 449 children (39%). In 40 of these (23%) hilar adenopathy was visible on frontal and lateral view, in 19 of the 176 confirmed cases (11%) only on a frontal view and in 22 (13%) on a lateral view only. Probable tuberculosis was diagnosed in a further 140 of the 449 children (31%), and hilar adenopathy was visible on frontal and lateral views in 39 of these children (28%), on the frontal view only in 8 (6%) and on the lateral view only in 27 (19%). In the symptomatic children investigated in the hospital, and the asymptomatic children investigated in the clinic, hilar adenopathy was detected on the lateral chest radiograph only in 36 (12%) and 14 (9%) cases respectively. Lateral chest radiographs will considerably improve the accuracy of the diagnosis of childhood tuberculosis. (orig.)

    A history of childhood trauma is reportedly more prevalent in people suffering from psychosis than in the general population. Childhood trauma has also been linked to cognitive abnormalities in adulthood, and cognitive abnormalities, in turn, are one of the key clinical features of psychosis. Therefore, this study investigated whether there was a relationship between childhood trauma and cognitive function in patients with first-episode psychosis. The potential impact of diagnosis (schizophrenia or affective psychosis) and gender on this association was also examined.

  16. Why x-ray chests

    International Nuclear Information System (INIS)

    In order to assess the validity of screening chest radiography at Chalk River Nuclear Laboratories, the yield of occult major disease and its significance to the afflicted employees have been examined over a ten year period. The study suggests that the incidence rate of occult disease which in retrospect proved to have been of major or life-threatening importance to the afflicted employee approximates 1 per 1000 population per annum. Major benefit accrued only to about 1 in 3 of these employees, the remainder gaining little more than that which would have followed treatment had their diseases presented symptomatically. These results are considered in relation to the health surveillance needs of a population generally and selectively exposed to diverse health hazards within the nuclear industry. (auth)

    Background. Spiral CT of the chest is an imaging technique with unequivocal indications and proven higher sensitivity and specificity than conventional chest X-rays. However, particularly in children, attempts should be made to reduce radiation exposure to a minimum. Objective. To evaluate whether a low-dose technique in spiral CT scanning results in adequate diagnostic information. Materials and methods. In a prospective study, 27 children (range 3 weeks to 14 years, mean 7 years) underwent a low-dose CT examination of the chest for various indications. The tube energy was 12.5 mAs (n = 5), 25 mAs (n = 17), 50 mAs (n = 3), or 75 mAs (n = 2) per slice. Two radiologists evaluated, in consensus, the CT scans with respect to their diagnostic value and comparison was made with 20 standard-dose chest CT examinations of adults (175 mAs per slice, mean age 56 years) with respect to technical image quality (noise and artefacts). In a second part of the study, dose measurements were carried out by means of exposing thermoluminescent dosimeters attached to a water/air phantom simulating a child's chest. Results. All low-dose CT scans were of diagnostic image quality and no additional studies were necessary. The average image noise was significantly higher than in standard-dose CT examinations (SD 39.5 compared with 12.5 for unenhanced soft tissue, P < 0.01), but did not hinder accurate diagnosis. Artefacts were exclusively due to patient motion. Radiation exposure per slice was approx. 4 mGy at 25 mAs and 34 mGy at 250 mAs, regardless of slice thickness. Conclusions. For all indications in paediatric CT scanning of the chest, low-dose technique provides adequate image quality without loss of diagnostic information. The radiation exposure is approximately 5-20 % of a standard-dose CT. (orig.) With 3 figs., 1 tab., 17 refs.

    In Western Europe the most frequent cause of multiple injuries is blunt trauma. Only few of us have experience with penetrating trauma, without exception far less than in the USA or South-Africa. In Rotterdam, the Erasmus Medical Centre is a level I trauma centre, situated directly in the town centre. All penetrating traumas are directly presented to our emergency department by a well organized ambulance service supported by a mobile medical team if necessary. The delay with scoop and run principles is very short for these cases, resulting in severely injured reaching the hospital alive in increasing frequency. Although the basic principles of trauma care according to the guidelines of the Advanced Trauma Life Support (ATLS) (1-2) are the same for blunt and penetrating trauma with regard to priorities, diagnostics and primary therapy, there are some pitfalls in the strategy of management in penetrating trauma one should be aware of. Simple algorithms can be helpful, especially in case of limited experience (3). In case of life-saving procedures, the principles of Damage Control Surgery (DCS) must be followed (4-5). This approach is somewhat different from "traditional" surgical treatment. In the Ist phase prompt interventions by emergency thoracotomy and laparotomy are carried out, with only two goals to achieve: surgical control of haemorrhage and contamination. After temporary life-saving procedures, the 2nd phase is characterized by intensive care treatment, dealing with hypothermia, metabolic acidosis and clotting disturbances. Finally in the 3rd phase, within 6-24 hours, definitive surgical care takes place. In this overview, penetrating injuries of neck, thorax, abdomen and extremities will be outlined. Penetrating cranial injuries, as a neurosurgical emergency with poor prognosis, are not discussed. History and physical examination remain the corner stones of good medical praxis.

    Abdominal trauma is a leading cause of death in children older than 1 year of age. The spleen is the most common organ injured following blunt abdominal trauma. Pediatric trauma patients present unique clinical challenges as compared to adults, including different mechanisms of injury, physiologic responses, and indications for operative versus nonoperative management. Splenic salvage techniques and nonoperative approaches are preferred to splenectomy in order to decrease perioperative risks, transfusion needs, duration/cost of hospitalization, and risk of overwhelming postsplenectomy infection. Early and accurate detection of splenic injury is critical in both adults and children; however, while imaging findings guide management in adults, hemodynamic stability is the primary determinant in pediatric patients. After initial diagnosis, the primary role of imaging in pediatric patients is to determine the level and duration of care. We present a comprehensive literature review regarding the mechanism of injury, imaging, management, and complications of traumatic splenic injury in pediatric patients. Multiple patients are presented with an emphasis on the American Association for the Surgery of Trauma organ injury grading system. Clinical practice guidelines from the American Pediatric Surgical Association are discussed and compared with our experience at a large community hospital, with recommendations for future practice guidelines.

    Full Text Available The treatment of children presenting dental trauma in the primary dentition requires a different approach from that used in the permanent dentition, because there is a very close relation between the apex of the traumatized primary tooth and the successor permanent bud. The possible consequences on the permanent teeth should be considered when performing early treatment in order to prevent further damage. Also, the probable trauma’s late sequelae should be taken into account both for primary and permanent dentition. Given the subject’s importance, this chapter aimed to report this issue broadly. This comprises the anamnesis, general, intraoral, and radiographic examination and the comprehensive treatment of the patient. Additionally to the classification of dental injuries, we highlighted the diagnosis, required treatment,prognosis, and follow-up of each clinical situation. A topic on soft tissue lesion was included, because it has a great impact on both the child and family. Moreover, it could be associated with other trauma types. Since the analysis of the child’s vaccination status is suggested, in face of cases demanding that tetanus vaccine be valid, the recommendation of the Brazilian Ministry of Health was also informed. Furthermore, there is an item on dental splinting, parenting advice, and trauma consequences on primary and successor permanent teeth. At the end of the chapter, two tables summarize the early and delayed treatment of trauma involving primary tooth’s enamel, dentin, pulp, and supportive tissues.

    Full Text Available Trauma is the most common non-obstetrical cause of death in pregnant women. Pregnancy must always be suspected in any female trauma patient of childbearing age until proved otherwise. Unique changes in anatomy and physiology that takes place during pregnancy alter the pathophysiology and location of maternal injuries in pregnancy, which may be significantly different from the non-pregnant state. Trauma from road traffic accidents, falls and domestic violence are the most common causes of abdominal blunt trauma. As pregnancy progresses, the change of accidental injury increases. Head and neck injuries, respiratory failure, and hypovolemic shock constitute the most frequent causes of trauma related maternal death in pregnancy. Even the pregnant woman with minor injuries should be carefully observed. Initial management is directed at resuscitation and stabilization of the mother that takes precedence over that of the fetus, unless vital signs cannot be maintained and perimortem cesarean section decided upon. Fetal monitoring should be maintained after satisfactory resuscitation and stabilization of the mother. Preventive measures include proper seat belt use and identifying and counseling victims of suspected domestic violence.

    A chest tube is used to drain the contents of the pleural space to reconstitute the physiologic pressures within the pleural space and to allow the lungs to fully expand. Indications for chest tube placement include pneumothorax, hemothorax, pleural effusion, pleural empyema, and major thoracic surgery. The most appropriate site for chest tube placement is the 4th or 5th intercostal space in the mid- or anterior- axillary line. Attention to technique in placing the chest tube is vital to avoid complications from the procedure. Applying the step-by-step technique presented, placement of a chest tube is a quick and safe procedure. Complications - frequently occurring when the tube is inserted with a steel trocar - include hemothorax, dislocation, lung lacerations, and injury to organs in the thoracic or abdominal cavity."

  5. In search of optimum chest radiography techniques

    International Nuclear Information System (INIS)

    A nation-wide study of chest radiography in Sweden previously revealed a large variation in the physical and technical factors involved, in particular radiation dose. In this study image quality could not be assessed unambiguously. The aim was to try to establish correlation between visual grading of radiographs and physical and technical factors in order to find the optimum chest X-ray system. The physical and technical performance of 24 chest units was evaluated. Radiographs were taken of an anthropomorphic chest phantom supplied with test structures simulating various pathologies. Image quality was assessed by visual grading analysis of the radiographs. The physical and technical parameters of the units rated best were used to exemplify good radiographic practice. Results were in agreement with the recommendations issued by the Commission of the European Communities (CEC). It was also shown that low radiation dose is compatible with high-quality radiographic imaging of the chest. (Author)

    Full Text Available A previously healthy 55-year-old man with right sided lateral chest pain admitted to clinic. It was found a solid and painful mass at the right 4th rib in physical examination. Chest X-ray and thoracic computarized tomography showed an opacity measured 60x33 mm within the right chest wall destructing the 4th rib. Needle aspiration was performed from tumor and cytologic examination showed atypic plasma cell infiltration. The patient was scheduled for a chest wall resection and reconstructive surgery. Examination of a permanent section showed that the chest wall tumor was solitary plasmacytoma. There was no evidence of multiple myeloma recurrence after two years from the operation.

  7. Spinal trauma: first aid from cross-sectional imaging

    International Nuclear Information System (INIS)

    The diagnosis of the traumatized spine is one of the key issues for trauma radiologists. The cross-sectional imaging procedures, computed tomography (CT) and magnetic resonance imaging (MRI) are the essential methods in spinal trauma radiology. These modalities are of great help in accurately assessing injury patterns and extent and in providing indications of patient outcome. In contrast to cross-sectional imaging, radiography has a role in the evaluation of minor spinal trauma only. It is generally accepted that trauma radiologists do not use typical classifications to evaluate the spine partly because such an ideal classification system does not yet exist. Not least because of this classification difficulty, eponyms and synonyms are widely used to describe traumatology of the spine as a high level of specific information is included in these various terms. The members of the trauma team should be aware of the strengths and limitations of the methods used in the assessment of the spine. This article provides a brief outline of fundamental knowledge about the diagnosis of spinal trauma. (orig.)

    Objective: The high burden of injuries in Iran necessitates the establishment of a comprehensive trauma care system. The purpose of this paper is to describe the current status of trauma system regarding the components and function. Methods: The current status of trauma system in all components of a trauma system was described through expert panels and semi-structured interviews with trauma specialists and policy makers.Results: Currently, various organizations are involved in prevention, management and rehabilitation of injuries,but an integrative system approach to trauma is rather deficient. There has been ongoing progress in areas of public education through media, traffic regulation reinforcement,hospital care and prehospital services. Meanwhile, there are gaps regarding financing, legislations and education of high risk groups. The issues on education and training standards of the front line medical team and continuing education and evaluation are yet to be addressed. Trauma registry has been piloted in some provinces, but as it needs the well-developed infrastructure (regarding staff, maintenance,financial resources), it is not yet established in our system of trauma care.Conclusions: It seems that one of the problems with trauma care in Iran is lack of coordination among trauma system organizations. Although the clinical management of trauma patients has improved in our country in the recent decade, decreasing the burden of injuries necessitates an organized approach to prevention and management of trauma in the context of a trauma system.

    Prior studies have suggested that physical trauma might be associated with the development of amyotrophic lateral sclerosis (ALS). We conducted a population-based, individually matched case-control study in Denmark to assess whether hospitalization for trauma is associated with a higher risk of developing ALS. There were 3,650 incident cases of ALS in the Danish National Patient Register from 1982 to 2009. We used risk-set sampling to match each case to 100 age- and sex-matched population controls alive on the date of the case's diagnosis. Odds ratios and 95% confidence intervals were calculated using a conditional logistic regression model. History of trauma diagnosis was also obtained from the Danish Patient Register. When traumas in the 5 years prior to the index date were excluded, there was a borderline association between any trauma and ALS (odds ratio (OR) = 1.09, 95% confidence interval (CI): 0.99, 1.19). A first trauma before age 55 years was associated with ALS (OR = 1.22, 95% CI: 1.08, 1.37), whereas first traumas at older ages were not (OR = 0.97, 95% CI: 0.85, 1.10). Our data suggest that physical trauma at earlier ages is associated with ALS risk. Age at first trauma could help explain discrepancies in results of past studies of trauma and ALS. PMID:26825926

    Full Text Available Background. The management and outcomes of occult hemopneumothorax in blunt trauma patients who required mechanical ventilation are not well studied. We aimed to study patients with occult hemopneumothorax on mechanical ventilation who could be carefully managed without tube thoracostomy. Methods. Chest trauma patients with occult hemopneumothorax who were on mechanical ventilation were prospectively evaluated. The presence of hemopneumothorax was confirmed by CT scanning. Hospital length of stay, complications, and outcome were recorded. Results. A total of 56 chest trauma patients with occult hemopneumothorax who were on ventilatory support were included with a mean age of 36 ± 13 years. Hemopneumothorax was managed conservatively in 72% cases and 28% underwent tube thoracostomy as indicated. 29% of patients developed pneumonia, 16% had Acute Respiratory Distress Syndrome (ARDS, and 7% died. Thickness of hemothorax, duration of mechanical ventilation, and development of ARDS were significantly associated with tube thoracostomy in comparison to no-chest tube group. Conclusions. The majority of occult hemopneumothorax can be carefully managed without tube thoracostomy in patients who required positive pressure ventilation. Tube thoracotomy could be restricted to those who had evidence of increase in the size of the hemothorax or pneumothorax on follow-up chest radiographs or developed respiratory compromise.

  13. Transfusion practices in trauma

    2014-01-01

    Full Text Available Resuscitation of a severely traumatised patient with the administration of crystalloids, or colloids along with blood products is a common transfusion practice in trauma patients. The determination of this review article is to update on current transfusion practices in trauma. A search of PubMed, Google Scholar, and bibliographies of published studies were conducted using a combination of key-words. Recent articles addressing the transfusion practises in trauma from 2000 to 2014 were identified and reviewed. Trauma induced consumption and dilution of clotting factors, acidosis and hypothermia in a severely injured patient commonly causes trauma-induced coagulopathy. Early infusion of blood products and early control of bleeding decreases trauma-induced coagulopathy. Hypothermia and dilutional coagulopathy are associated with infusion of large volumes of crystalloids. Hence, the predominant focus is on damage control resuscitation, which is a combination of permissive hypotension, haemorrhage control and haemostatic resuscitation. Massive transfusion protocols improve survival in severely injured patients. Early recognition that the patient will need massive blood transfusion will limit the use of crystalloids. Initially during resuscitation, fresh frozen plasma, packed red blood cells (PRBCs and platelets should be transfused in the ratio of 1:1:1 in severely injured patients. Fresh whole blood can be an alternative in patients who need a transfusion of 1:1:1 thawed plasma, PRBCs and platelets. Close monitoring of bleeding and point of care coagulation tests are employed, to allow goal-directed plasma, PRBCs and platelets transfusions, in order to decrease the risk of transfusion-related acute lung injury.

    Objectives: Trauma is the greatest cause of morbidity and mortality in paediatric/adolescent populations worldwide. This study aimed to describe trauma mechanisms, patterns and outcomes among children with blunt torso trauma admitted to the Sultan Qaboos University Hospital (SQUH) in Muscat, Oman. Methods: This retrospective single-centre study involved all children ≤12 years old with blunt torso trauma admitted for paediatric surgical care at SQUH between January 2009 and December 2013. Medical records were analysed to collect demographic and clinical data. Results: A total of 70 children were admitted with blunt torso trauma during the study period, including 39 (55.7%) male patients. The mean age was 5.19 ± 2.66 years. Of the cohort, 35 children (50.0%) received their injuries after having been hit by cars as pedestrians, while 19 (27.1%) were injured by falls, 12 (17.1%) during car accidents as passengers and four (5.7%) by falling heavy objects. According to computed tomography scans, thoracic injuries were most common (65.7%), followed by abdominal injuries (42.9%). The most commonly involved solid organs were the liver (15.7%) and spleen (11.4%). The majority of the patients were managed conservatively (92.9%) with a good outcome (74.3%). The mortality rate was 7.1%. Most deaths were due to multisystem involvement. Conclusion: Among children with blunt torso trauma admitted to SQUH, the main mechanism of injury was motor vehicle accidents. As a result, parental education and enforcement of infant car seat/child seat belt laws are recommended. Conservative management was the most successful approach. PMID:27226913

    We previously proposed a computerized index (eccentricity index [EI]) for chest-wall deformity measurements, such as pectus excavatum. We sought to define mean shapes based on normal chest walls and to propose for computerized index reference values of that are used in the quantitative analysis of the severity of chest-wall deformities. A total of 584 patients were classified into 18 groups, and a database of their chest-wall computed tomography (CT) scan images was constructed. The boundaries of the chest wall were extracted by using a segmentation algorithm, and the mean shapes were subsequently developed. The reference index values were calculated from the developed mean shapes. Reference index values for the EI were compared with a conventional index, the Haller index (HI). A close association has been shown between the two indices in multiple subjects (r = 0.974, P < 0.001). The newly developed mean shapes and reference index values supply both reliability and objectivity to the diagnosis, analysis, and treatment of chest-wall deformities. They promise to be highly useful in clinical settings.

  17. Dynamic chest radiography: flat-panel detector (FPD) based functional X-ray imaging.

    Science.gov (United States)

    Tanaka, Rie

    2016-07-01

    Dynamic chest radiography is a flat-panel detector (FPD)-based functional X-ray imaging, which is performed as an additional examination in chest radiography. The large field of view (FOV) of FPDs permits real-time observation of the entire lungs and simultaneous right-and-left evaluation of diaphragm kinetics. Most importantly, dynamic chest radiography provides pulmonary ventilation and circulation findings as slight changes in pixel value even without the use of contrast media; the interpretation is challenging and crucial for a better understanding of pulmonary function. The basic concept was proposed in the 1980s; however, it was not realized until the 2010s because of technical limitations. Dynamic FPDs and advanced digital image processing played a key role for clinical application of dynamic chest radiography. Pulmonary ventilation and circulation can be quantified and visualized for the diagnosis of pulmonary diseases. Dynamic chest radiography can be deployed as a simple and rapid means of functional imaging in both routine and emergency medicine. Here, we focus on the evaluation of pulmonary ventilation and circulation. This review article describes the basic mechanism of imaging findings according to pulmonary/circulation physiology, followed by imaging procedures, analysis method, and diagnostic performance of dynamic chest radiography.

    Full Text Available Blood and blood components are considered drugs because they are used in the treatment of diseases. As with any drug, adverse effects may occur, necessitating careful consideration of therapy. Like any other therapeutic decision, the need for transfusion should be considered on the basis of risks and benefits and alternative treatments available to avoid over- and under-transfusion. This review is focused on the blood transfusion protocol in trauma patients with hemorrhagic shock. Besides, issues related to emergency and massive transfusion have also been elaborated. We conducted a comprehensive MEDLINE search and reviewed the relevant literature, with particular reference to emergency medical care in trauma.
