Blunt trauma to the chest wall and rib fractures are remarkably frequent and are the basis of considerable morbidity and possible mortality. Surgical remedies for highly displaced rib fractures, especially in cases of flail chest, have been undertaken intermittently for more than 50 years. Rib-specific plating systems have started to be used in the last 10 years. These have ushered in the modern era of rib repair with chest wall stabilization (CWS) techniques that are safer, easier to perform, and more efficient. Recent consensus statements have sought to define the indications and contraindications, as well as the when, the how, and the technical details of CWS. Repair should be considered for patients who have three or more displaced rib fractures or a flail chest, whether or not mechanical ventilation is required. Additional candidates include patients who fail non-operative management irrespective of fracture pattern and those with rib fractures who need thoracic procedures for other reasons. Traditionally, unstable spine fracture and severe traumatic brain injury are definite contraindications. Pulmonary contusion’s role in the decision to perform CWS remains controversial. A range of rib-specific plating systems are now commercially available. PMID:29744222

Optimal use of whole-body counting data to estimate pulmonary deposition of many of the actinides is dependent upon accurate measurement of the thickness of the chest wall because of severe attenuation of low-energy x rays and photons associated with the decay of these radionuclides. An algorithm for estimation of female chest wall thicknesses, verified by real-time ultrasonic measurements, has been derived based on the correlation of measured chest wall thickness and other common biometric quantities. Use of this algorithm will reduce the error generally associated with estimation of internal actinide deposition previously resulting from assuming an average chest wall thickness for all female subjects

The authors have used MR imaging to study 22 patients who had intrathoracic, pleura-related malignancies and whose CT findings had suggested chest wall invasion. ECG-gated T1- and T2-weighted spin-echo sequences were used in all patients. Additionally, in 10 patients an ungated, multisection, gradient-echo sequence was used, which was repeated after intravenous administration of Gd-DTPA in five patients. Surgery confirmed chest wall invasion in 19 patients. CT showed tumor invasion only in 14 of these 19 patients. MR imaging showed high-signal-intensity lesion within chest wall and pleura in T2-weighted and Gd-DTPA-enhanced T1-weighted images as the typical pattern of chest wall invasion in all 19 patients. Two of the three patients with pleural inflammation and without chest wall invasion had high-signal-intensity pleural lesions, but none of these lesions were within the chest wall

Full Text Available Air bags are an automatic crash protection system. They have been shown to reduce mortality from motor vehicle accidents by 31% following direct head-on impacts, by 19% following any frontal impact and by 11% overall. Despite obvious benefits there has been a corresponding increase in the number of injuries resulting from their deployment. We describe a case of a pneumothorax in the absence of chest wall pathology associated with airbag deployment, in a belted driver. There has been one previous description of pneumothorax associated with airbag deployment, in an unbelted driver.

Background Chest injuries constitute a continuing challenge to the trauma or general surgeon practicing in developing countries. This study was conducted to outline the etiological spectrum, injury patterns and short term outcome of these injuries in our setting. Patients and methods This was a prospective study involving chest injury patients admitted to Bugando Medical Centre over a six-month period from November 2009 to April 2010 inclusive. Results A total of 150 chest injury patients were studied. Males outnumbered females by a ratio of 3.8:1. Their ages ranged from 1 to 80 years (mean = 32.17 years). The majority of patients (72.7%) sustained blunt injuries. Road traffic crush was the most common cause of injuries affecting 50.7% of patients. Chest wall wounds, hemothorax and rib fractures were the most common type of injuries accounting for 30.0%, 21.3% and 20.7% respectively. Associated injuries were noted in 56.0% of patients and head/neck (33.3%) and musculoskeletal regions (26.7%) were commonly affected. The majority of patients (55.3%) were treated successfully with non-operative approach. Underwater seal drainage was performed in 39 patients (19.3%). One patient (0.7%) underwent thoracotomy due to hemopericardium. Thirty nine patients (26.0%) had complications of which wound sepsis (14.7%) and complications of long bone fractures (12.0%) were the most common complications. The mean LOS was 13.17 days and mortality rate was 3.3%. Using multivariate logistic regression analysis, associated injuries, the type of injury, trauma scores (ISS, RTS and PTS) were found to be significant predictors of the LOS (P trauma scores (ISS, RTS and PTS), the need for ICU admission and the presence of complications (P Chest injuries resulting from RTCs remain a major public health problem in this part of Tanzania. Urgent preventive measures targeting at reducing the occurrence of RTCs is necessary to reduce the incidence of chest injuries in this region. PMID:21244706

Ultrasonic measurements of chest wall thickness and realistic chest phantom for calibration of Pu lung counting facilities

International Nuclear Information System (INIS)

Shirotani, Takashi

1990-01-01

There are four important problems for the measurements of chest wall thickness using ultrasonic device: (1) selection of optimum position of transducer and the number of measured points on the chest covered with detector, (2) estimation of adipose-to-muscle ratio in the chest wall, especially for dispersed adipose like 'marbled beef', (3) determination of regression equations for the prediction of chest wall thickness, derived from groups of different body shape, i.e. corpulent and lean, and (4) estimation of effective chest wall thickness involved self-absorption layer of lung tissue, which changes with distribution of activity in the lungs. This quantity can not be measured with ultrasonic device. Realistic chest phantom was developed. The phantom contains removable model organs (lungs, liver, kidneys and heart), model trachea and artificial rib cage, and also includes chest plates that can be placed over the chest to simulate wide range adipose-to-muscle ratio in the chest wall. Various soft tissue substitutes were made of polyurethane with different concentrations of additive, and the rib cage were made of epoxy resin with calcium carbonate. The experimental data have shown that the phantom can be used as a standard phantom for the calibration. (author)

With the view of examining possible chest wall invasion of bronchogenic carcinoma, Cine-MRI was performed on 22 such cases. These cases were suspected of having above chest wall invasion by CT and their histopathological findings were obtained in surgery. The judgment of the chest wall invasion by Cine-CT was made such that non-moving up and down of the tumor with respiration involves its invasion, moving of the tumor without any up-and-down movement suspects its invasion and moving up and down of the tumor with respiration involves no invasion. The chest wall invasion was observed in 5 of 7 cases of invasion judged by Cine-MRI. For 2 false-positive cases, the histopathological findings presumed that tumor cells disappeared from the chest wall invaded region as the result of preoperative chemotherapy. The above invasion was observed in 1 of 4 cases suspected of possible invasion. Correct diagnosis was formed of 11 cases judged invasion-free by Cine-MRI. The above results suggested Cine-MRI to be useful for diagnosis of chest wall invasion of bronchogenic carcinoma. (author)

Objective: To estimate the visually lossless threshold (VLT) for the Joint Photographic Experts Group (JPEG) 2000 compression of chest CT images and to demonstrate the variance of the VLT between the lung and mediastinum/chest wall. Subjects and methods: Eighty images were compressed reversibly (as negative control) and irreversibly to 5:1, 10:1, 15:1 and 20:1. Five radiologists determined if the compressed images were distinguishable from their originals in the lung and mediastinum/chest wall. Exact tests for paired proportions were used to compare the readers' responses between the reversible and irreversible compressions and between the lung and mediastinum/chest wall. Results: At reversible, 5:1, 10:1, 15:1, and 20:1 compressions, 0%, 0%, 3-49% (p < .004, for three readers), 69-99% (p < .001, for all readers), and 100% of the 80 image pairs were distinguishable in the lung, respectively; and 0%, 0%, 74-100% (p < .001, for all readers), 100%, and 100% were distinguishable in the mediastinum/chest wall, respectively. The image pairs were less frequently distinguishable in the lung than in the mediastinum/chest wall at 10:1 (p < .001, for all readers) and 15:1 (p < .001, for two readers). In 321 image comparisons, the image pairs were indistinguishable in the lung but distinguishable in the mediastinum/chest wall, whereas there was no instance of the opposite. Conclusion: For JPEG2000 compression of chest CT images, the VLT is between 5:1 and 10:1. The lung is more tolerant to the compression than the mediastinum/chest wall.

2003-12-01

Full Text Available Background. Major thoracic trauma is consistent with high mortality rate because of associated injuries of vital thoracic organs and dangerous complications. The flail chest occurs after disruption of the skeletal continuity of chest wall and demands because of its pathophysiological complexity rapid and accurate diagnosis and treatment.Conclusions. Basic pathophysiological mechanism of the flail chest is respiratory distress, which is provoked by pulmonary contusions and paradoxical chest wall motion. The treatment should be pointed to improvement and support of respiratory functions and include aggressive pain control, pulmonary physiotherapy and selective mechanical ventilation. Views about operative fixation of the flail chest are still controversial. Neither mortality rate neither long-term disability are improved after operative fixation.

Purpose: To determine patient, tumor, and treatment factors related to the development of late chest wall toxicity after lung stereotactic body radiotherapy (SBRT). Methods and Materials: We reviewed a registry of 134 patients treated with lung SBRT to 60 Gy in 3 fractions who had greater than 1 year of clinical follow-up and no history of multiple treatments to the same lobe (n = 48). Patients were treated as per Radiation Therapy Oncology Group Protocol 0236 without specific chest wall avoidance criteria. The chest wall was retrospectively contoured. Thirty-two lesions measured less than 3 cm, and sixteen measured 3 to 5 cm. The median planning target volume was 29 cm{sup 3}. Results: With a median follow-up of 18.8 months, 10 patients had late symptomatic chest wall toxicity (4 Grade 1 and 6 Grade 2) at a median of 8.8 months after SBRT. No patient characteristics (age, diabetes, hypertension, peripheral vascular disease, or body mass index) were predictive for toxicity, whereas there was a trend for continued smoking (p = 0.066; odds ratio [OR], 4.4). Greatest single tumor dimension (p = 0.047; OR, 2.63) and planning target volume (p = 0.040; OR, 1.04) were correlated with toxicity, whereas distance from tumor edge to chest wall and gross tumor volume did not reach statistical significance. Volumes of chest wall receiving 30 Gy (V30) through 70 Gy (V70) were all highly significant, although this correlation weakened for V65 and V70 and maximum chest wall point dose only trended to significance (p = 0.06). On multivariate analysis, tumor volume was no longer correlated with toxicity and only V30 through V60 remained statistically significant. Conclusions: Tumor size and chest wall dosimetry are correlated to late chest wall toxicity. Only chest wall V30 through V60 remained significant on multivariate analysis. Restricting V30 to 30 cm{sup 3} or less and V60 to 3 cm{sup 3} or less should result in a 10% to 15% risk of late chest wall toxicity or lower.

Full Text Available Chest wall defect may be caused by many factors such as the resection of tumor and trauma, and the reconstruction of bone-defection is still the key point of thoracic surgery. With the development of material science, more and more new materials have been used in medical practice, which makes huge progress in the surgery of chest wall. However, none of these materials satisfy all the practical needs of the reconstruction. Recently, with the development of the capacity of computer, 3D-printing technology has been gradually used in clinical work, and the idea of individual treatment has been accepted by more and more people. The weakness of these materials may be solved by the new material and the application of individual treatment, which could also make great advance in chest wall surgery. This article will make a summary of the research on the reconstruction of chest wall.

2013-12-01

In this paper, we present an automatic method to segment the chest wall in automated 3D breast ultrasound images. Determining the location of the chest wall in automated 3D breast ultrasound images is necessary in computer-aided detection systems to remove automatically detected cancer candidates beyond the chest wall and it can be of great help for inter- and intra-modal image registration. We show that the visible part of the chest wall in an automated 3D breast ultrasound image can be accurately modeled by a cylinder. We fit the surface of our cylinder model to a set of automatically detected rib-surface points. The detection of the rib-surface points is done by a classifier using features representing local image intensity patterns and presence of rib shadows. Due to attenuation of the ultrasound signal, a clear shadow is visible behind the ribs. Evaluation of our segmentation method is done by computing the distance of manually annotated rib points to the surface of the automatically detected chest wall. We examined the performance on images obtained with the two most common 3D breast ultrasound devices in the market. In a dataset of 142 images, the average mean distance of the annotated points to the segmented chest wall was 5.59 ± 3.08 mm. Copyright © 2012 Elsevier B.V. All rights reserved.

Clinical Findings in Patients with Splenic Injuries: Are Injuries to the Left Lower Chest Important?

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 wall fractures, including injuries to the ribs and sternum, usually heal spontaneously without specific treatment. However, a small subset of patients have fractures that produce overlying bone fragments that may produce severe pain, respiratory compromise, and, if untreated mechanically, result in nonunion. We performed open reduction and internal fixation on seven patients with multiple rib fractures-five in the initial hospitalization and two delayed--as well as 35 sternal fractures (19 immediate fixation and 16 delayed). Operative fixation was accomplished using titanium plates and screws in both groups of patients. All patients with rib fractures did well; there were no major complications or infections, and no plates required removal. Clinical results were excellent. There was one death in the sternal fracture group in a patient who was ventilator-dependent preoperatively and extubated himself in the early postoperative period. Otherwise, the results were excellent, with no complications occurring in this group. Three patients had their plates removed after boney union was achieved. No evidence of infection or nonunion occurred. The excellent results achieved in the subset of patients with severe chest wall deformities treated initially at our institution and those referred from outside suggest that operative fixation is a useful modality that is likely underused.

Chest wall – a structure underestimated in ultrasonography. Part III: Neoplastic lesions

Full Text Available Chest wall neoplasms mainly include malignancies, metastatic in particular. Differential diagnosis should include clinical data; tumor location, extent, delineation; the degree of homogeneity; the presence of calcifications; the nature of bone destruction and the degree of vascularization. The aim of the paper is to present both the benefits and limitations of ultrasound for the diagnosis of chest wall neoplasms. The neoplastic process may be limited to the chest wall; it may spread from the chest wall into the intrathoracic structures or spread from the inside of the chest towards the chest wall. Benign tumors basically originate from vessels, nerves, bones, cartilage and soft tissues. In this paper, we briefly discuss malformations of blood and lymphatic vessels, glomus tumor as well as neurogenic tumors originating in the thoracic branches of the spinal nerves and the autonomic visceral system. Metastases, particularly lung, breast, kidney cancer, melanoma and prostate cancer, are predominant tumors of the osteocartilaginous structures of the chest wall. Plasma cell myeloma is also relatively common. The vast majority of these lesions are osteolytic, which is reflected in ultrasound as irregular cortical defects. Osteoblastic foci result only in irregular outline of the bone surface. Lipomas are the most common neoplasms of the chest wall soft tissue. Elastofibroma is another tumor with characteristic echostructure. Desmoid fibromatosis, which is considered to be a benign lesion with local aggressivity and recurrences after surgical resection, represents an interesting tumor form the clinical point of view. Ultrasonography represents an optimal tool for the monitoring of different biopsies of pathological lesions located in the chest wall. Based on our experiences and literature data, this method should be considered as a preliminary diagnosis of patients with chest wall tumors.

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.

2013-01-01

Background A subcutaneous implantable cardioverter defibrillator (S-ICD) could ease placement and reduce complications of transvenous ICDs, but requires more energy than transvenous ICDs. Therefore we assessed cardiac and chest wall damage caused by the maximum energy shocks delivered by both types of clinical devices. Methods During sinus rhythm, anesthetized pigs (38±6 kg) received an S-ICD (n = 4) and five 80-Joule (J) shocks, or a transvenous ICD (control, n = 4) and five 35-J shocks. An inactive S-ICD electrode was implanted into the same control pigs to study implant trauma. All animals survived 24-hours. Troponin I and creatine kinase muscle isoenzyme (CK-MM) were measured as indicators of myocardial and skeletal muscle injury. Histopathological injury of heart, lungs, and chest wall was assessed using semi-quantitative scoring. Results Troponin I was significantly elevated at 4- and 24-hours (22.6±16.3 and 3.1±1.3 ng/ml; baseline 0.07±0.09 ng/ml) in control pigs but not in S-ICD pigs (0.12±0.11 and 0.13±0.13 ng/ml; baseline 0.06±0.03 ng/ml). CK-MM was significantly elevated in S-ICD pigs after shocks (6544±1496 and 9705±6240 U/L; baseline 704±398 U/L) but not in controls. ECG changes occurred post-shock in controls but not in S-ICD pigs. The myocardium and lungs were histologically normal in both groups. Subcutaneous injury was greater in S-ICD compared to controls. Conclusion Although CK-MM suggested more skeletal muscle injury in S-ICD pigs, significant cardiac, lung, and chest wall histopathological changes were not detected in either group. Troponin I data indicate significantly less cardiac injury from 80-J S-ICD shocks than 35-J transvenous shocks. PMID:23713608

Full Text Available An unusual penetrating chest injury was caused by high velocity road traffic accident. An 18-year-old had a four wheeler accident and was brought in emergency department with a ′bamboo′ stick on the left side chest exiting through back. After the stabilization of vital parameters, an inter-costal tube drainage was done on the left side. Except the minor brochopleural fistula which healed by 10 th day, his recovery was uneventful. The outcome was consistent with current aggressive management of penetrating chest injuries. Management of penetrating chest injury involving pulmonary trauma is based on three principles. One is stabilization of hemodynamics of patient with proper clinical evaluation. Second, a mere intercostal tube drainage sufficient for majority of the cases. Third, post-operative active as well as passive physiotherapy is necessary for speedy recovery.

Full Text Available The chest wall is a vast and complex structure, hence the wide range of pathological conditions that may affect it. The aim of this publication is to discuss the usefulness of ultrasound for the diagnosis of benign lesions involving the thoracic wall. The most commonly encountered conditions include sternal and costal injuries and thoracic lymphadenopathy. Ultrasound is very efficient in identifying the etiology of pain experienced in the anterior chest wall following CPR interventions. Both available literature and the authors’ own experience prompt us to propose ultrasound evaluation as the first step in the diagnostic workup of chest trauma, as it permits far superior visualization of the examined structures compared with conventional radiography. Sonographic evaluation allows correct diagnosis in the case of various costal and chondral defects suspicious for cancer. It also facilitates diagnosis of such conditions as degenerative lesions, subluxation of sternoclavicular joints (SCJs and inflammatory lesions of various etiology and location. US may be used as the diagnostic modality of choice in conditions following thoracoscopy or thoracotomy. It may also visualize the fairly common sternal wound infection, including bone inflammation. Slipping rib syndrome, relatively little known among clinicians, has also been discussed in the study. A whole gamut of benign lesions of thoracic soft tissues, such as enlarged lymph nodes, torn muscles, hematomas, abscesses, fissures, scars or foreign bodies, are all easily identified on ultrasound, just like in other superficially located organs.

Full Text Available Goal of research: to evaluate efficiency of videothoracoscopy in diagnosis and treatment of patients with injuries and emergency diseases ща chest organs.Material and methods: Study wasbased on treatment results analysis of 2111 patients with injuries and chest organs emergency diseases, who were treated at Republican Research Centre of Emergency Medicine in 2001-2014. Chest trauma made up 1396 (66,1% victims. There were 477 (22,6% patients with spontaneous pneumothorax. At the stages of initial diagnosis, the radiologic evaluations, CT investigations and videothoracoscopies were performed. In chest trauma patients the videothoracoscopy underwent in 844 cases, in spontaneous pneu#mothorax this method was employed in 290 patients. Complicated forms of lung echinococcosis were observed in 238 (11,3% patients and complicated forms of lung echinococcosis were evident in 72 patients.Results. Videothoracoscopy and video-assisted interventions allowed to eliminate lungs and pleura pathology in 1206 (57,1% patients, whereas the traditional methods were effective only in 905 cases (42,9%.Conclusions. Investigation methods such as multiplanar radioscopy, radiography, chest CT and videothora-coscopy must be included into algorithm of diagnosis and surgical treatment of chest injuries and emergency diseases of chest organs. At chest trauma the videothoracoscopy allows to avoid broad thoracotomy from 9,4% to 4,7% of cases, to reduce the frequency of repeated interventions from 17,4% to 0,5% and diminish a number of early postsurgery complications from 25,4% to 10,9%. Videothoracoscopy of chest traumas allows to reduce frequency of repeated interventions from 19,8 to 1,7%.

Chest imaging plays a prominent role in blunt trauma patient evaluation, but indiscriminate imaging is expensive, may delay care, and unnecessarily exposes patients to potentially harmful ionizing radiation. To improve diagnostic chest imaging utilization, we conducted 3 prospective multicenter studies over 12years to derive and validate decision instruments (DIs) to guide the use of chest x-ray (CXR) and chest computed tomography (CT). The first DI, NEXUS Chest x-ray, consists of seven criteria (Age >60years; rapid deceleration mechanism; chest pain; intoxication; altered mental status; distracting painful injury; and chest wall tenderness) and exhibits a sensitivity of 99.0% (95% confidence interval [CI] 98.2-99.4%) and a specificity of 13.3% (95% CI, 12.6%-14.0%) for detecting clinically significant injuries. We developed two NEXUS Chest CT DIs, which are both highly reliable in detecting clinically major injuries (sensitivity of 99.2%; 95% CI 95.4-100%). Designed primarily to focus on detecting major injuries, the NEXUS Chest CT-Major DI consists of six criteria (abnormal CXR; distracting injury; chest wall tenderness; sternal tenderness; thoracic spine tenderness; and scapular tenderness) and exhibits higher specificity (37.9%; 95% CI 35.8-40.1%). Designed to reliability detect both major and minor injuries (sensitivity 95.4%; 95% CI 93.6-96.9%) with resulting lower specificity (25.5%; 95% CI 23.5-27.5%), the NEXUS CT-All rule consists of seven elements (the six NEXUS CT-Major criteria plus rapid deceleration mechanism). The purpose of this review is to synthesize the three DIs into a novel, cohesive summary algorithm with practical implementation recommendations to guide selective chest imaging in adult blunt trauma patients.

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.

Given the high local control rates observed in breast cancer patients undergoing chest wall irradiation by kilovoltage x-rays, we aimed to revisit this treatment modality by accurate calculation of dose distributions using Monte Carlo simulation. The machine components were simulated using the MCNPX code. This model was used to assess the dose distribution of chest wall kilovoltage treatment in different chest wall thicknesses and larger contour or fat patients in standard and mid sternum treatment plans. Assessments were performed at 50 and 100 cm focus surface distance (FSD) and different irradiation angles. In order to evaluate different plans, indices like homogeneity index, conformity index, the average dose of heart, lung, left anterior descending artery (LAD) and percentage target coverage (PTC) were used. Finally, the results were compared with the indices provided by electron therapy which is a more routine treatment of chest wall. These indices in a medium chest wall thickness in standard treatment plan at 50 cm FSD and 15 degrees tube angle was as follows: homogeneity index 2.57, conformity index 7.31, average target dose 27.43 Gy, average dose of heart, lung and LAD, 1.03, 2.08 and 1.60 Gy respectively and PTC 11.19%. Assessments revealed that dose homogeneity in planning target volume (PTV) and conformity between the high dose region and PTV was poor. To improve the treatment indices, the reference point was transferred from the chest wall skin surface to the center of PTV. The indices changed as follows: conformity index 7.31, average target dose 60.19 Gy, the average dose of heart, lung and LAD, 3.57, 6.38 and 5.05 Gy respectively and PTC 55.24%. Coverage index of electron therapy was 89% while it was 22.74% in the old orthovoltage method and also the average dose of the target was about 50 Gy but in the given method it was almost 30 Gy. The results of the treatment study show that the optimized standard and mid sternum treatment for different chest

Stabilizing techniques of flail chest injuries usually need wide approaches to the chest wall. Three main regions need to be considered when stabilizing the rib cage: median-anterior with dissection of pectoral muscle; lateral-axillary with dissection of musculi (mm) serratus, externus abdominis; posterior inter spinoscapular with division of mm rhomboidei, trapezius and latissimus dorsi. Severe morbidity due to these invasive approaches needs to be considered. This study discusses possibilities for minimized approaches to the shown regions. Fifteen patients were stabilized by locked plate osteosynthesis (MatrixRib ® ) between May 2012 and April 2014 and prospectively followed up. Flail chest injuries were managed through limited incisions to the anterior, the lateral, and the posterior parts of the chest wall or their combinations. Each approach was 4-10 cm using Alexis ® retractor. One minimized approach offered sufficient access at least to four ribs posterior and laterally, four pairs of ribs anterior in all cases. There was no need to divide latissimus dorsi muscle. Trapezius und rhomboid muscles were only limited divided, whereas a subcutaneous dissection of serratus and abdominis muscles was necessary. A follow-up showed sufficient consolidation. pneumothorax (2) and seroma (2). Minimized approaches allow sufficient stabilization of severe dislocated rib fractures without extensive dissection or division of the important muscles. Keeping the arm and, thus, the scapula mobile is very important for providing the largest reachable surface of the rib cage through each approach.

Full Text Available Introduction: Neck and thoracic trauma in children pose unforeseen challenges requiring variable management strategies. Here, we describe some unusual cases. Patients and Methods: Pediatric cases of unusual neck and thoracic trauma prospectively managed from April 2012 to March 2014 at a Level 1 trauma center were studied for management strategies, outcome, and follow-up. Results: Six children with a median age of 5.5 (range 2–10 years were managed. Mechanism of injury was road traffic accident, fall from height and other accidental injury in 2, 3 and 1 patient respectively. The presentation was respiratory distress and quadriplegia, exposed heart, penetrating injury in neck, dysphagia and dyspnea, and swelling over the chest wall in 1, 1, 1, 2 and 1 cases respectively. Injuries included lung laceration, open chest wall, vascular injury of the neck, tracheoesophageal fistula (2, and chest wall posttraumatic pyomyositis. One patient had a flare of miliary tuberculosis. Immediate management included chest wall repair; neck exploration and repair, esophagostomy, gastroesophageal stapling, and feeding jejunostomy (followed by gastric pull-up 8 months later. Chest tube insertion and total parenteral nutrition was required in one each. 2 and 4 patients required tracheostomy and mechanical ventilation. The patient with gastric pull-up developed a stricture of the esophagogastric anastomosis that was revised at 26-month follow-up. At follow-up of 40–61 months, five patients are well. One patient with penetrating neck injury suffered from blindness due to massive hemorrhage from the vascular injury in the neck and brain ischemia with only peripheral vision recovery. Conclusion: Successful management of neck and chest wall trauma requires timely appropriate decisions with a team effort.

PURPOSE OF THE STUDY Thoracic trauma, one of the most frequent injuries in patients with multiple traumata, is found in 50 to 80% of these patients and it is crucial for the patient's prognosis. It accounts for 25% of all death from polytraumatic injuries. The aim of this retrospective study was an analysis of the occurrence of chest injuries in polytrauma patients and their surgical treatment in the Trauma Centre or Department of Surgery of the University Hospital Pilsen in a five-year period. MATERIAL AND METHODS Patients with injuries meeting the definition of polytrauma and an Injury Severity Score (ISS) ≥16 were included. The demographic characteristics, mechanism of multiple trauma, ISS value and chest injury were recorded in each patient. The number of injured patients in each year of the study was noted. In the patients with chest injury, the type of injury and method of treatment were assessed. The therapy was further analysed including its timing. The number of deaths due to polytrauma involving chest injury, the cause of death and its time in relation to the patient's admission to the Trauma Centre were evaluated. RESULTS In the period 2010-14, 513 polytrauma patients were treated; of them 371 (72.3%) were men with an average age of 40.5 years. The most frequent cause of injury was a traffic accident (74%). The average ISS of the whole group was 35 points. Chest injury was diagnosed in 469 patients (91.4%) of whom only five (1.1%) had penetrating injury. Pulmonary contusion was most frequent (314 patients; 67%). A total of 212 patients with chest injury underwent surgery (45.2%); urgent surgery was performed in 143 (67.5%), acute surgery in 49 (23.1%) and delayed surgery in 63 (29.7%) patients. Chest drainage was the major surgical procedure used in the whole group. Of 61 patients who died, 52 had chest injury. In this subgroup the most frequent cause of death was decompensated traumatic shock (26 patients; 50%). In the whole group, 32 polytrauma

There are currently no evidence-based indications for surgical stabilization of rib fractures (SSRF) in patients without flail chest. The purpose of this survey was to identify patients for whom there is relative equipoise (operative vs. non-operative) in order to assist in designing a randomized clinical trial. Members of the Chest Wall Injury Society were sent an online survey, in which 18 patient scenarios were presented. The baseline patient had ≥ three displaced, contiguous fractures and had no other contraindications for surgery. This default scenario was then varied based upon patient age, degree of traumatic brain injury (TBI), fracture series location, and number of abnormal pulmonary physiologic variables (oxygen requirement, respiratory rate, incentive spirometry ability, cough, and numeric pain score). Thirty respondents provided a total of 540 answers. Overall, the majority of responses were in favor of SSRF (n = 413, 84.1%). Furthermore, the vast majority of responses indicated that some degree of pulmonary compromise was necessary to recommend SSRF (n = 44, 90.4%), with ≥ two abnormal parameters being the most common threshold (n = 156, 31.8%). Decision to recommend SSRF varied significantly by number of abnormal clinical variables, age, and degree of TBI, but not by fracture series location. Patients aged 85 years old and those with moderate TBI were the least likely to be recommended for SSRF, regardless of abnormal pulmonary physiologic variables. The most appropriate cutoff for equipoise appeared to be a patient aged 21-79 years old, with no or mild TBI, ≥ two abnormal pulmonary parameters, and regardless of fracture location (44.8% consensus for SSRF). SSRF was recommended for most patients with non-flail, displaced rib fractures. However, this recommendation was contingent upon patient age, degree of TBI, and pulmonary clinical status. Results of this survey may be used to inform inclusion criteria for a future randomized

The reconstruction of full-thickness chest wall defects is a challenging problem for thoracic surgeons, particularly after a wide resection of the chest wall that includes the sternum. The location and the size of the defect play a major role when selecting the method of reconstruction, while acceptable cosmetic and functional results remain the primary goal. Improvements in preoperative imaging techniques and reconstruction materials have an important role when planning and performing a wide chest wall resection with a low morbidity rate. In this report, we describe the reconstruction of a wide anterior chest wall defect with a patient-specific custom-made titanium implant. An infected mammary tumour recurrence in a 62-year old female, located at the anterior chest wall including the sternum, was resected, followed by a large custom-made titanium implant. Latissimus dorsi flap and split-thickness graft were also used for covering the implant successfully. A titanium custom-made chest wall implant could be a viable alternative for patients who had large chest wall tumours. PMID:24227881

A subcutaneous implantable cardioverter defibrillator (S-ICD) could ease placement and reduce complications of transvenous ICDs, but requires more energy than transvenous ICDs. Therefore we assessed cardiac and chest wall damage caused by the maximum energy shocks delivered by both types of clinical devices. During sinus rhythm, anesthetized pigs (38 ± 6 kg) received an S-ICD (n = 4) and five 80-Joule (J) shocks, or a transvenous ICD (control, n = 4) and five 35-J shocks. An inactive S-ICD electrode was implanted into the same control pigs to study implant trauma. All animals survived 24 hours. Troponin I and creatine kinase muscle isoenzyme (CK-MM) were measured as indicators of myocardial and skeletal muscle injury. Histopathological injury of heart, lungs, and chest wall was assessed using semiquantitative scoring. Troponin I was significantly elevated at 4 hours and 24 hours (22.6 ± 16.3 ng/mL and 3.1 ± 1.3 ng/mL; baseline 0.07 ± 0.09 ng/mL) in control pigs but not in S-ICD pigs (0.12 ± 0.11 ng/mL and 0.13 ± 0.13 ng/mL; baseline 0.06 ± 0.03 ng/mL). CK-MM was significantly elevated in S-ICD pigs after shocks (6,544 ± 1,496 U/L and 9,705 ± 6,240 U/L; baseline 704 ± 398 U/L) but not in controls. Electrocardiogram changes occurred postshock in controls but not in S-ICD pigs. The myocardium and lungs were histologically normal in both groups. Subcutaneous injury was greater in S-ICD compared to controls. Although CK-MM suggested more skeletal muscle injury in S-ICD pigs, significant cardiac, lung, and chest wall histopathological changes were not detected in either group. Troponin I data indicate significantly less cardiac injury from 80-J S-ICD shocks than 35-J transvenous shocks. ©2013, The Authors. Journal compilation ©2013 Wiley Periodicals, Inc.

Chest wall trauma is a common cause of morbidity and mortality. Recent technological advances and scientific publications have created a renewed interest in surgical fixation of flail chest. However, definitive data supporting surgical fixation are lacking, and its virtues have not been evaluated against modern, comprehensive management protocols. Consecutive patients undergoing rib fracture fixation with rib-specific locking plates at 2 regional trauma centres between July 2010 and August 2012 were matched to historical controls with similar injury patterns and severity who were managed nonoperatively with modern, multidisciplinary protocols. We compared short- and long-term outcomes between these cohorts. Our patient cohorts were well matched for age, sex, injury severity scores and abbreviated injury scores. The nonoperatively managed group had significantly better outcomes than the surgical group in terms of ventilator days (3.1 v. 6.1, p = 0.012), length of stay in the intensive care unit (3.7 v. 7.4 d, p = 0.009), total hospital length of stay (16.0 v. 21.9 d, p = 0.044) and rates of pneumonia (22% v. 63%, p = 0.004). There were no significant differences in long-term outcomes, such as chest pain or dyspnea. Although considerable enthusiasm surrounds surgical fixation of flail chest injuries, our analysis does not immediately validate its universal implementation, but rather encourages the use of modern, multidisciplinary, nonoperative strategies. The role of rib fracture fixation in the modern era of chest wall trauma management should ultimately be defined by prospective, randomized trials.

Short-T1 inversion-recovery (STIR) sequences have greater constant, less motion sensitivity, and require shorter imaging times than conventional T2-weighted spin-echo (SE) sequences and are therefore particularly useful for staging chest wall malignancies. MR studies of 49 patients with possible chest wall malignancies were reviewed. Images were produced at 0.15 T with a variety of SE sequences. Forty-five also had STIR (repetition time, 1,400 - 2,100; echo time, 36 or 40; inversion time, 100 or 125). MR studies indicated chest wall involvement in 39 of 49 patients; 12 had obvious rib encasement, the most definitive finding. IN 13, lesions detected on STIR were either not visible or seen only in retrospect on T1 SE images. In five of five, STIR was clearly superior to T2 SE for delineation of tumor margins. The authors have discontinued using T2 SE sequences for chest neoplasms in favor of the higher contrast and sensitivity of STIR

Chest computed tomography (CT) diagnoses more injuries than chest radiography, so-called occult injuries. Wide availability of chest CT has driven substantial increase in emergency department use, although the incidence and clinical significance of chest CT findings have not been fully described. We determine the frequency, severity, and clinical import of occult injury, as determined by changes in management. These data will better inform clinical decisions, need for chest CT, and odds of intervention. Our sample included prospective data (2009 to 2013) on 5,912 patients at 10 Level I trauma center EDs with both chest radiography and chest CT at physician discretion. These patients were 40.6% of 14,553 enrolled in the parent study who had either chest radiography or chest CT. Occult injuries were pneumothorax, hemothorax, sternal or greater than 2 rib fractures, pulmonary contusion, thoracic spine or scapula fracture, and diaphragm or great vessel injury found on chest CT but not on preceding chest radiography. A priori, we categorized thoracic injuries as major (having invasive procedures), minor (observation or inpatient pain control >24 hours), or of no clinical significance. Primary outcome was prevalence and proportion of occult injury with major interventions of chest tube, mechanical ventilation, or surgery. Secondary outcome was minor interventions of admission rate or observation hours because of occult injury. Two thousand forty-eight patients (34.6%) had chest injury on chest radiography or chest CT, whereas 1,454 of these patients (71.0%, 24.6% of all patients) had occult injury. Of these, in 954 patients (46.6% of injured, 16.1% of total), chest CT found injuries not observed on immediately preceding chest radiography. In 500 more patients (24.4% of injured patients, 8.5% of all patients), chest radiography found some injury, but chest CT found occult injury. Chest radiography found all injuries in only 29.0% of injured patients. Two hundred and two

A wide variety of diseases manifest as palpable chest wall masses in children. These include normal variation, congenital anomalies, trauma, infection, axillary lymphadenopathies, soft tissue tumors and bone tumors. Given that most of these diseases are associated with chest wall deformity, diagnosis is difficult by physical examination or ultrasonography alone. However, multi-detector CT with three dimensional reconstruction is useful in the characterization and differential diagnosis of palpable chest wall lesions. In this article, we review the spectrum of palpable chest wall diseases and illustrate their multi-detector CT presentation.

Primary chest wall abscess occurring after blunt chest trauma is rare. We present the case of a 50-year-old woman who presented with a swelling in her left breast. The patient had experienced blunt chest trauma 2 months back. Needle aspiration revealed pus formation in the patient's chest. Computed tomography revealed a mass in the lower region of the left mammary gland, with thickening of the parietal pleura and skin and fracture of the fifth rib under the abscess. Following antibiotic administration and irrigation of the affected region, surgical debridement was performed. During surgery, we found that the pectoralis major muscle at the level of the fifth rib was markedly damaged, although the necrotic tissue did not contact the mammary gland. We diagnosed the lesion as a chest wall abscess that occurred in response to blunt chest trauma. Her postoperative course was uneventful. There has been no recurrence for six months after surgery.

Methods Prospective, observational, cohort study of patients attending 58 private practices over a five-week period from March to May 2001 with undifferentiated chest pain. During a one-year follow-up, questionnaires including detailed history and physical exam, were filled out at initial consultation, 3 and 12 months. The outcomes were: clinical characteristics associated with the CWS diagnosis and clinical evolution of the syndrome.

Outcome at one year was favourable even though CWS recurred in half of patients. Conclusion CWS is common and benign, but leads to anxiety and recurred frequently. Because the majority of chest wall pain is left-sided, the possibility of coexistence with coronary disease needs careful consideration.

Background The epidemiology of chest pain differs strongly between outpatient and emergency settings. In general practice, the most frequent cause is the chest wall pain. However, there is a lack of information about the characteristics of this syndrome. The aims of the study are to describe the clinical aspects of chest wall syndrome (CWS). Methods Prospective, observational, cohort study of patients attending 58 private practices over a five-week period from March to May 2001 with undifferentiated chest pain. During a one-year follow-up, questionnaires including detailed history and physical exam, were filled out at initial consultation, 3 and 12 months. The outcomes were: clinical characteristics associated with the CWS diagnosis and clinical evolution of the syndrome. Results Among 24 620 consultations, we observed 672 cases of chest pain and 300 (44.6%) patients had a diagnosis of chest wall syndrome. It affected all ages with a sex ratio of 1:1. History and sensibility to palpation were the keys for diagnosis. Pain was generally moderate, well localised, continuous or intermittent over a number of hours to days or weeks, and amplified by position or movement. The pain however, may be acute. Eighty-eight patients were affected at several painful sites, and 210 patients at a single site, most frequently in the midline or a left-sided site. Pain was a cause of anxiety and cardiac concern, especially when acute. CWS coexisted with coronary disease in 19 and neoplasm in 6. Outcome at one year was favourable even though CWS recurred in half of patients. Conclusion CWS is common and benign, but leads to anxiety and recurred frequently. Because the majority of chest wall pain is left-sided, the possibility of coexistence with coronary disease needs careful consideration. PMID:17850647

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.

Purpose: In the Cooperative Ewing's Sarcoma Study 86 and the European Intergroup Cooperative Ewing's Sarcoma Study 92, hemithorax irradiation (RT) was performed in patients with Ewing tumors of the chest wall involving the pleura or contaminating the pleural cavity. In a retrospective analysis, the outcomes of these patients were evaluated and compared with those of patients with chest wall tumors who did not receive hemithorax RT. Methods and Materials: Between 1985 and 1996, 138 patients presented with nonmetastatic Ewing tumors of the chest wall. They were treated in a multimodal treatment regimen that included polychemotherapy and local therapy depending on the tumor characteristics. Hemithorax RT was performed at a dose of 15 Gy for patients <14 years old and 20 Gy for patients ≥14 years old. Forty-two patients received hemithorax RT (Group 1) and 86 patients did not (Group 2). The data were insufficient for the other 10 patients. Results: Comparing both groups, the initial pleural effusion, pleural infiltration, and intraoperative contamination of the pleural space were significantly more frequent in Group 1. The event-free survival rate after 7 years was 63% for patients in Group 1 and 46% for patients in Group 2 (not statistically significant). The 7-year local relapse rate (including combined local-systemic relapses) was 12% in Group 1 and 10% in Group 2; the corresponding systemic relapse rates were 22% and 39%. Conclusion: Patients with chest wall tumors who received hemithorax RT were negatively selected; yet the rate of event-free survival was better for patients who received hemithorax RT than for those who did not (although the difference was not statistically significant). This result was due to a reduction of metastases, mainly lung metastases. Local control was equivalent between the two groups. These favorable results have caused us to continue using hemithorax RT to treat high-risk patients with Ewing tumors of the chest wall

Surgical rib fixation (SRF) for severe rib fracture injuries is generating increasing interest in the medical literature. It is well documented that poorly healed fractured ribs can lead to chronic pain, disability, and deformity. An unanswered question in SRF for flail chest injury is whether it is sufficient to fix one fracture per rib, on successive ribs, thus converting a flail chest injury into simple fractured ribs, or whether both ends of the floating segment of the chest wall should be fixed. This study aimed to analyze SRF in flail chest injury, assessing 3-month outcomes for nonfixed fractured rib ends in the flail segment. This is a retrospective review (2005-2013) of 60 consecutive patients who underwent SRF for flail chest injury admitted to the Alfred Hospital, Melbourne, Australia. Imaging by three-dimensional computed tomography (3D CT) of the chest at admission was compared with follow-up 3D CT at 3 months after injury. The 3-month CT scans were assessed for degree of healing and presence of residual deformity at the fracture fixation site. Follow-up CT was performed in 52 of the 60 patients. At 3 months after surgery, 86.5% of the patients had at least partial healing with good alignment and adequate fracture stabilization. Hardware failure was noted in five patients (9.6%) and occurred with the absorbable prostheses only. Six patients who had preoperative overlapping or displacement showed no improvement in deformity despite fixing the lateral fractures. Callus formation and bony bridging between adjacent ribs was often noted in the rib fractures not fixed (28 of 52 patients, 54%) This retrospective review of 3D CT chest at 3 months after rib fixation indicates that a philosophy of fixing only one fracture per rib in a flail segment does not avoid deformity and displacement, particularly in posterior rib fractures.

The goal of this study was to analyze the patterns, therapeutic modalities, and short-term outcomes of patients with chest injuries in the aftermath of the Wen-Chuan earthquake, which occurred on May 12, 2008 and registered 8.0 on the Richter scale. Of the 1522 patients who were referred to the West China Hospital of Sichuan University from May 12 to May 27, 169 patients (11.1%) had suffered major chest injuries. The type of injury, the presence of infection, Abbreviated Injury Score (AIS 2005), New Injury Severity Score (NISS), treatment, and short-term outcome were all documented for each case. Isolated chest injuries were diagnosed in 129 patients (76.3%), while multiple injuries with a major chest trauma were diagnosed in 40 patients (23.7%). The mean AIS and the median NISS of the hospitalized patients with chest injuries were 2.5 and 13, respectively. The mortality rate was 3.0% (5 patients). Most of the chest injuries were classified as minor to moderate trauma; however, coexistent multiple injuries and subsequent infection should be carefully considered in medical response strategies. Coordinated efforts among emergency medical support groups and prior training in earthquake preparedness and rescue in earthquake-prone areas are therefore necessary for efficient evacuation and treatment of catastrophic casualties.

Herniation of unruptured tuberculous lung abscess into chest wall without pleural or bronchial spillage

Rahul Magazine

2011-01-01

Full Text Available A 22-year-old unmarried man presented to the chest outpatient department with a history of productive cough of two-month duration. He also complained of pain and swelling on the anterior aspect of right side of chest of one-month duration. Imaging studies of the thorax, including chest roentgenography and computerized tomography, revealed an unruptured lung abscess which had herniated into the chest wall. Culture of pus aspirated from the chest wall swelling grew Mycobacterium tuberculosis. He was diagnosed to have a tuberculous lung abscess which had extended into the chest wall, without spillage into the pleural cavity or the bronchial tree. Antituberculosis drugs were prescribed, and he responded to the treatment with complete resolution of the lesion.

From 1980 to October 1985 we treated 45 breast cancer patients with electron arc therapy. This technique was used in situations where optimal treatment with fixed photon or electron beams was technically difficult: long scars, recurrent tumor extending across midline or to the posterior thorax, or marked variation in depth of target tissue. Forty-four patients were treated following mastectomy: 35 electively because of high risk of local failure, and 9 following local recurrence. One patient with advanced local regional disease was treated primarily. The target volume boundaries on the chest wall were defined by a foam lined cerrobend cast which rested on the patient during treatment, functioning as a tertiary collimator. A variable width secondary collimator was used to account for changes in the radius of the thorax from superior to inferior border. All patients had computerized tomography performed to determine Internal Mammary Chain depth and chest wall thickness. Electron energies were selected based on these thicknesses and often variable energies over different segments of the arc were used. The chest wall and regional node areas were irradiated to 45 Gy-50 Gy in 5-6 weeks by this technique. The supraclavicular and upper axillary nodes were treated by a direct anterior photon field abutted to the superior edge of the electron arc field. Follow-up is from 10-73 months with a median of 50 months. No major complications were observed. Acute and late effects and local control are comparable to standard chest wall irradiation. The disadvantages of this technique are that the preparation of the tertiary field defining cast and CT treatment planning are labor intensive and expensive. The advantage is that for specific clinical situations large areas of chest wall with marked topographical variation can be optimally, homogeneously irradiated while sparing normal uninvolved tissues

Chest Trauma in Athletic Medicine.

Phillips, Nicholas R; Kunz, Derek E

2018-03-01

While overall sports participation continues at high rates, chest injuries occur relatively infrequently. Many conditions of chest injury are benign, related to simple contusions and strains, but the more rare, severe injuries carry a much higher risk of morbidity and mortality than the typical issues encountered in athletic medicine. Missed or delayed diagnosis can prove to be catastrophic. Sports medicine providers must be prepared to encounter a wide range of traumatic conditions relating to the torso, varying from the benign chest wall contusion to the life-threatening tension pneumothorax. Basic field-side management should be rapid and focused, using the standardized approach of Advanced Traumatic Life Support protocol. Early and appropriate diagnosis and management can help allow safe and enjoyable sports participation.

[The theory of cardiac lesions from blunt chest injury].

2010-01-01

The main theories of myocardial lesions associated with a blunt chest injury proposed starting from the XIXth century till the present time are considered based on the overview of the literature data. It is shown that the theory of selective mechanical activation of ATP-dependent K+ channels is most promising for further investigations into the mechanisms of myocardial dysfunction resulting from blunt chest injuries. The authors emphasize the absence of the universally accepted theory explaining the mechanism behind traumatic cardiac troubles and its fatal outcome despite numerous studies of cardiac lesions in patients with a blunt chest injury. It dictates the necessity of further research, both clinical and experimental, for a deeper insight into the problem.

Conventionally, opposed tangential fields are used for the treatment of chest wall irradiation. If the chest wall is treated in the linac, 4 or 6 MV photons will be the energy of choice. It is a welI-established rule that for chest wall separations up to 22 cm, one can use mid-energies, with acceptable volume of hot spots. For larger patient sizes (22 cm and above), mid-energy beams produce hot spots over large volumes. The purpose of this work is to compare plans made with 6 and 15 MV photons, for patients with large chest wall separations. The obvious disadvantage in using high-energy photons for chest wall irradiation is inadequate dose to the skin. But this can be compensated by using a bolus of suitable thickness

Purpose: Stereotactic body radiation therapy (SBRT) is increasingly being used to treat thoracic tumors. We attempted here to identify dose-volume parameters that predict chest wall toxicity (pain and skin reactions) in patients receiving thoracic SBRT. Patients and Methods: We screened a database of patients treated with SBRT between August 2004 and August 2008 to find patients with pulmonary tumors within 2.5 cm of the chest wall. All patients received a total dose of 50 Gy in four daily 12.5-Gy fractions. Toxicity was scored according to the NCI-CTCAE V3.0. Results: Of 360 patients in the database, 265 (268 tumors) had tumors within 30 , or volume of the chest wall receiving 30 Gy. Body mass index (BMI) was also strongly associated with the development of chest pain: patients with BMI ≥29 had almost twice the risk of chronic pain (p = 0.03). Among patients with BMI >29, diabetes mellitus was a significant contributing factor to the development of chest pain. Conclusion: Safe use of SBRT with 50 Gy in four fractions for lesions close to the chest wall requires consideration of the chest wall volume receiving 30 Gy and the patient's BMI and diabetic state.

Precise diagnostics and an adequate therapeutic approach are mandatory in the treatment of air leak in polytrauma patients with blunt chest trauma. The aim of this study was to evaluate the incidence, characteristics, and management of air leak following this injury pattern. Data from 110 polytrauma patients was collected retrospectively. Fifty-four patients received initial treatment by chest tube placement for pneumothorax. These patients were classified into two groups, one with severe air leak and one with minor air leak. An evaluation of injury pattern, chest wall injuries in particular, duration of air leak, reason for drainage maintenance in place, hospital length of stay, ICU stay, ventilator duration, type of treatment, and the delay to surgical intervention was performed. Whereas 4 patients showed severe air leak and were subsequently scheduled for timely surgical intervention, the remaining 50 patients only showed minor air leak. Only 7 patients with minor air leak suffered from prolonged air leak (>5days), which spontaneously resolved in all of them after a mean duration of 7.7days (range 6-12days). Absence of a prolonged air leak resulted in a shorter length of stay and a shorter duration of mechanical ventilation, although no statistical significance was observed. Early spontaneous cessation of most minor air leaks as well as early surgical intervention for severe air leak lead to very satisfactory patient outcomes with a relatively short hospital stay in our patients. We therefore advocate early surgery for lacerations of the pulmonary parenchyma resulting in severe air leak, whereas minor air leaks can usually be treated conservatively.

We herein report the case of 75-year-old Japanese female with a community-acquired lung abscess attributable to Streptococcus pneumoniae (S. penumoniae) which extended into the chest wall. The patient was admitted to our hospital with a painful mass on the left anterior chest wall. A contrast-enhanced chest computed tomography scan showed a lung abscess in the left upper lobe which extended into the chest wall. Surgical debridement of the chest wall abscess and percutaneous transthoracic tube drainage of the lung abscess were performed. A culture of the drainage specimen yielded S. pneumoniae. The patient showed a remarkable improvement after the initiation of intravenous antibiotic therapy.

The aim of this study was to compare retrospectively the characteristics of chest injuries and frequencies of other, concurrent injuries in patients after earthquakes of different seismic intensity. We compared the cause, type, and body location of chest injuries as well as the frequencies of other, concurrent injuries in patients admitted to our hospital after the Wenchuan and Lushan earthquakes in Sichuan, China. 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. 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. 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-related chest injuries.

Full Text Available PURPOSE. The aim of our retrospective study was to analyze the patterns of associated thoracic injuries in patients underwent blunt chest trauma and rib fractures. METHODS. The study included 212 patients with rib fractures due to blunt thoracic trauma. The mechanism of trauma, the type of rib fracture and the type of associated injuries were analyzed. RESULTS. The patients were divided in two groups according to the number of fractured ribs-group I included the patients with up to two fractured ribs (72 patients-33,9%, and group II – with ≥3 fractured ribs (140 patients-66,1%. Associated chest injuries were present in 36 of the patients from group I (50%, and in 133 patients from group II (95%. Pulmonary contusion was the most common intrathoracicinjurie-65,6% of the cases. The mean hospital stay was 8, 7 days. The lethality rate was 16,9% -all of them due to the associated chest injuries. CONCLUSIONS. The mortality related to rib fractures is affected by the associated thoracic injuries, the advanced age, and the number of fractured ribs.

Surgical treatment of chest instability

Fractures of the ribs is the most common thoracic injury after blunt trauma. Chest wall instability (flail chest) is a common occurrence in the presence of multiple ribs fracture. Unilateral or bilateral fractures more ribs anteriorly or posteriorly will produce enough instability that paradoxical respiratory motion results in hypoventilation of an unacceptable degree. Open approach and surgical stabilisation of the chest preserved pulmonary function, improved pain control, minimized posttraumatic deformities and shorter back to work time. (author)

Chest wall – underappreciated structure in sonography. Part I: Examination methodology and ultrasound anatomy

Andrzej Smereczyński

2017-09-01

Full Text Available Chest wall ultrasound has been awarded little interest in the literature, with chest wall anatomy described only in limited extent. The objective of this study has been to discuss the methodology of chest wall ultrasound and the sonographic anatomy of the region to facilitate professional evaluation of this complex structure. The primarily used transducer is a 7–12 MHz linear one. A 3–5 MHz convex (curvilinear transducer may also be helpful, especially in obese and very muscular patients. Doppler and panoramic imaging options are essential. The indications for chest wall ultrasound include localized pain or lesions found or suspected on imaging with other modalities (conventional radiography, CT, MR or scintigraphy. The investigated pathological condition should be scanned in at least two planes. Sometimes, evaluation during deep breathing permits identification of pathological mobility (e.g. in rib or sternum fractures, slipping rib syndrome. Several structures, closely associated with each other, need to be considered in the evaluation of the chest wall. The skin, which forms a hyperechoic covering, requires a high frequency transducer (20–45 MHz. The subcutaneous fat is characterized by clusters of hypoechoic lobules. Chest muscles have a very complex structure, but their appearance on ultrasound does not differ from the images of muscles located in other anatomical regions. As far as cartilaginous and bony structures of the chest are concerned, the differences in the anatomy of the ribs, sternum, scapula and sternoclavicular joints have been discussed. The rich vascular network which is only fragmentarily accessible for ultrasound assessment has been briefly discussed. A comprehensive evaluation of the chest wall should include the axillary, supraclavicular, apical and parasternal lymph nodes. Their examination requires the use of elastography and contrast-enhanced ultrasound.

A review of prospectively collected data in our trauma unit for the years 1998-2003 was undertaken. Adult patients who suffered multiple trauma with an Injury Severity Score (ISS) of >/=16, admitted to hospital for more than 72 hours and with sustained blunt chest injuries were included in the study. Demographic details including pre-hospital care, trauma history, admission vital signs, blood transfusions, details of injuries and their abbreviated injury scores (AIS), operations, length of intensive care unit and hospital stays, Injury Severity Score (ISS) and mortality were analysed. Fulfilling the inclusion criteria with at least one chest injury were 1,164 patients. The overall mortality reached 18.7%. As expected, patients in the higher AIS groups had both a higher overall ISS and mortality rate with one significant exception; patients with minor chest injuries (AIS(chest) = 1) were associated with mortality comparable to injuries involving an AIS(chest) = 3. Additionally, the vast majority of polytraumatised patients with an AIS(chest) = 1 died in ICU sooner than patients of groups 2-5.

Background Pediatric chest injuries were infrequent in our practice, but the outbreak of the Syrian crisis resulted in an increase in number and a change in the pattern of thoracic trauma incidents. We compared our experience of pediatric chest injuries before and during the crisis. Methods We reviewed the records of 256 children aged 12.8 ± 5 years who were admitted to our hospital with the diagnosis of chest trauma over a 12-year period. Collected data included mechanism of injury, associated injuries, method of management, length of hospital stay, complications, and mortality. Results The incidence of pediatric chest injuries increased significantly following the outbreak of the crisis, and penetrating injuries prevailed, mainly due to shrapnel, bullets, and stab wounds. Forty percent of patients with blunt injuries and 20% of those with penetrating injuries were managed conservatively, whereas urgent thoracotomies were indicated in 10%, mostly in patients with penetrating injuries. Associated injuries were more frequent in patients with blunt injuries and resulted in a longer hospital stay and an increased mortality rate. The overall mortality rate was 7.8% and it was higher in children younger than 7 years of age and in patients who had been subjected to blunt injuries. Conclusions There has been a recent substantial upsurge in the incidence of pediatric thoracic trauma, with a predominance of penetrating injuries. Most patients could be managed nonoperatively, but a small subset required an open thoracotomy. The presence of associated injuries constitutes the main determinant of prognosis in this group of patients.

To evaluate the technical aspects, results and complications of patients with implanted anterior chest wall port. Between April 1997 and June 1999, a total of 63 implanted ports were placed at the anterior chest wall of 63 consecutive patients by interventional radiologists. The indications were chemotherapy in 61 patients and total parenteral nutrition in two. The peripheral portion of the subclavian vein was punctured under fluoroscopic guidance via ipsilateral peripheral vein during venography. A central venous catheter was placed in the superior vena cava, and using the subcutaneous tunneling method, a connected infusion port was implanted at the anterior chest wall. Results and complications were reviewed, and by means of Kaplan-Meier survival analysis, the expected patency of the port was determined. The technical success rate for implanted port at the anterior chest wall was 100% (63/63 patients). In two patients, hematoma and oozing were treated by compression. The duration of port implantation ranged from 12 to 855 (mean, 187) days, and the port patency rate was 305.7±47.6 days. In seven patients (completed chemotherapy (n=3D3), central venous thrombosis (n=3D3) catheter-related infection (n=3D1)), the port was removed. Catheter obstruction occurred in two patients, and in one, the use of urokinase led to successful recanalization. Sixteen patients died of an underlying malignancy, but no catheter-related death was noted. Implantation of an anterior chest wall port is a safe and useful procedure, with long patency, for patients requiring chemotherapy and long-term venous access. (author)

This review was conducted to compare the contributions of chest X-ray (CXR) and computed tomography (CT) towards detecting intrathoracic damage in patients with penetrating war injuries to the chest and to determine whether identification of additional injuries by chest CT will have an impact on the choice of therapeutic interventions and clinical outcomes. We reviewed records of 449 patients (374 men, mean age 29.3 ± 14.8 years) who were admitted to our hospital with penetrating war injuries to the chest over a 7-year period. Collected data included mechanisms of injury, associated injuries, results of CXRs and chest CTs, methods of management, in-hospital stays, complications and mortalities. Immediate screening CXRs were obtained in all patients not requiring emergent thoracotomies, of which 91.4% showed positive signs of injury. Chest CTs were performed at the discretion of the physicians in 49.4% of patients, and CXR-positive findings were confirmed in all cases, while revealing additional injuries in 11% of patients. Chest CT findings led to additional closed chest drainage in 5.6% of patients but had no impact on treatment strategy in 94.4% of scanned patients. Follow-up CXRs showed new positive findings in 22 patients, leading to additional closed chest drainage in 3 patients and delayed open thoracotomies in 7 other patients. CXRs continue as the primary diagnostic modality in the assessment of patients with penetrating war injuries to the chest. Chest CTs can be omitted in most patients, thus reducing CT imaging case-load substantially, while most clinically significant chest injuries remain sufficiently recognized.

Reverse Abdominoplasty Flap in Reconstruction of Post-Bilateral Mastectomies Anterior Chest Wall Defect

2014-01-01

Full Text Available Reverse abdominoplasty was originally described for epigastric lift. Since the work by Baroudi and Huger in the 1970s, it has become clear that reverse abdominoplasty application can be extended beyond just aesthetic procedure. Through the knowledge of anterior abdominal wall vascularity, its application had included reconstructive prospect in the coverage of various chest wall defects. To date, reverse abdominoplasty flap has been used to reconstruct unilateral anterior chest wall defect or for larger defect but only in combination with other reconstructive techniques. Here, we presented a case where it is used as a standalone flap to reconstruct bilateral anterior chest wall soft tissue defect post-bilateral mastectomies in oncological resection. In conclusion, reverse abdominoplasty flap provided us with a simple, faster, and satisfactory reconstructive outcome.

We present the case of a 42-year-old woman with metastatic synovial sarcoma of parotid origin, treated definitively with chemoradiation, who subsequently developed oligometastatic disease limited to the lungs. She underwent multiple left and right lung wedge resections and left lower lobectomy, followed by right lower lobe stereotactic ablative radiotherapy (SABR), 54 Gy in three fractions to a right lower lobe lesion abutting the chest wall. Two years later, she was treated with cryoablation for a separate right upper lobe nodule abutting the chest wall. Two months later, she presented with acute shortness of breath, pleuritic chest pain, decreased peripheral blood O2 saturation, and productive cough. A computed tomography (CT) scan demonstrated severe chest wall necrosis in the area of recent cryoablation that, in retrospect, also received a significant radiation dose from her prior SABR. This case demonstrates that clinicians should exercise caution in using cryoablation when treating lung tumors abutting a previously irradiated chest wall. Note: Drs. Loo and Shah contributed equally as co-senior authors.

Chest and spine radiography abnormality in blunt chest trauma correlated with major vessel injury in an unselected patient population

Fernandez, G.; Kadir, S.; Encarnacion, C.

1989-01-01

To assess the true incidence of major vessel injury, the authors retrospectively reviewed all arch aortograms obtained for blunt chest trauma (BCT) during a 24-month period beginning December 1986. Aortograms were correlated with preangiographic chest radiographic and operative findings. The goals of this review were to examine the usefulness of commonly employed screening criteria for aortography and determine whether thoracic spine fractures imply a decreased likelihood of aortic injury. One hundred twenty aortograms were obtained during this period. The incidence of aortic laceration was 6.7%, and 7.5% had brachiocerebral vascular injury. Only 51% of chest radiographs were suggestive of vascular injury. Two patients with subtle radiographic findings had aortic laceration. One patient with a burst fracture of T-4 had aortic laceration. The results of this review indicate the incidence of great vessel injury is as high as that of injury to the aorta itself and that the presence of spine fractures does not exclude vascular injury

We wished to compare the ability of ultrasonography and radiography performed on the same day to detect rib fractures in minor chest injuries. Two hundred and fifteen patients with minor chest injuries were selected. Radiography and ultrasonography were performed on the same day with these patients. Chest wall pain was the only presenting symptom. Two radiologists performed ultrasonography. Fractures were identified by a disruption of the anterior margin of the rib and costal cartilage. The incidence and location of fractures and complications revealed by radiography and ultrasonography were compared. Radiographs revealed the presence of 70 rib fractures in 50 (23%) of 215 patients and ultrasonography revealed the presence of 203 rib fractures in 133 (62%) of 215 patients. Ultrasonography uniquely identified 133 rib fractures in 83 patients. Ultrasonography identified a 2.9 fold increase in the number of fractures in a 2.6 fold number of subjects as compared to radiography. Of the 203 sonographically detected fractures, 201 were located in the rib, one was located at the costochondral junction, and one in the costal cartilage. There were no complications seen by either radiography or ultrasonography. Ultrasonography reveals more fractures than those that may be overlooked on radiography for minor chest injuries.

The stress index (SI), a parameter derived from the shape of the pressure-time curve, can identify injurious mechanical ventilation. We tested the hypothesis that adjusting tidal volume (VT) to a non-injurious SI in an open lung condition avoids hypoventilation while preventing overdistension in an experimental model of combined lung injury and low chest-wall compliance (Ccw). Lung injury was induced by repeated lung lavages using warm saline solution, and Ccw was reduced by controlled intra-abdominal air-insufflation in 22 anesthetized, paralyzed and mechanically ventilated pigs. After injury animals were recruited and submitted to a positive end-expiratory pressure (PEEP) titration trial to find the PEEP level resulting in maximum compliance. During a subsequent four hours of mechanical ventilation, VT was adjusted to keep a plateau pressure (Pplat) of 30 cmH2O (Pplat-group, n = 11) or to a SI between 0.95 and 1.05 (SI-group, n = 11). Respiratory rate was adjusted to maintain a 'normal' PaCO2 (35 to 65 mmHg). SI, lung mechanics, arterial-blood gases haemodynamics pro-inflammatory cytokines and histopathology were analyzed. In addition Computed Tomography (CT) data were acquired at end expiration and end inspiration in six animals. PaCO2 was significantly higher in the Pplat-group (82 versus 53 mmHg, P = 0.01), with a resulting lower pH (7.19 versus 7.34, P = 0.01). We observed significant differences in VT (7.3 versus 5.4 mlKg(-1), P = 0.002) and Pplat values (30 versus 35 cmH2O, P = 0.001) between the Pplat-group and SI-group respectively. SI (1.03 versus 0.99, P = 0.42) and end-inspiratory transpulmonary pressure (PTP) (17 versus 18 cmH2O, P = 0.42) were similar in the Pplat- and SI-groups respectively, without differences in overinflated lung areas at end- inspiration in both groups. Cytokines and histopathology showed no differences. Setting tidal volume to a non-injurious stress index in an open lung condition improves

One-stage reconstruction of chest wall defects with greater omentum transplantation

Energy Technology Data Exchange (ETDEWEB)

Harashina, T [Keio Univ., Tokyo (Japan). School of Medicine; Oshiro, T; Sato, K

1976-11-01

Reconstructive operation by greater omentum transplantation in two cases of chest wall ulcer due to radiation therapy following an operation of breast cancer was introduced. The exposed dose of one case was not clarified, but that of another case was 5000 rad. This operation method is an excellent one, because operation is completed at one-stage and reconstruction of tissue is great owing to good blood circulation. It was thought that this method must be used more positively in the treatment of chest wall ulcer due to irradiation which is difficult to be treated.

The objective of this study was to determine the utility of CT scan findings for the diagnosis of chest wall tuberculosis, excluding the spine. We reviewed 15 patients (13 Africans and 2 Indians) with chest wall tuberculosis, retrospectively. The radiologic examination consisted of a plain X-ray and a CT scan of the chest for each patient. The site of disease was the rib in 13 patients or the body of the sternum in 2 patients. One rib was involved in 11 patients, 2 contiguous ribs (one site) in 2 patients, and bilateral disease (two sites) was observed in the remaining patient. The 14 rib sites involved the posterior arc or costovertebral joint in 11 cases, the anterior arc in 2 cases, and the anterior and middle arc in 1 case. The CT scan findings were an abscess (n = 14) or a soft tissue mass (n = 2), osteolytic lesions (n = 13), periosteal reaction (n = 10), and sequestrum (n = 14). Bone sclerosis was observed only in 3 cases of rib involvement. The association of a soft tissue abscess, an osteolytic lesion, and sequestrum, especially in immigrants to France, suggests chest wall tuberculosis on CT scan. (orig.)

In patients after chest trauma, imaging plays a key role for both, the primary diagnostic work-up, and the secondary assessment of potential treatment. Despite its well-known limitations, the anteroposterior chest radiograph remains the starting point of the imaging work-up. Adjunctive imaging with computed tomography, that recently is increasingly often performed on multidetector computed tomography units, adds essential information not readily available on the conventional radiograph. This allows better definition of trauma-associated thoracic injuries not only in acute traumatic aortic injury, but also in pulmonary, tracheobronchial, cardiac, diaphragmal, and thoracic skeletal injuries. This article reviews common radiographic findings in patients after chest trauma, shows typical imaging features resulting from thoracic injury, presents imaging algorithms, and recalls to the reader less common but clinically relevant entities encountered in patients after thoracic trauma

In patient with blunt trauma of chest, supine AP x-ray cannot differentiate the lung contusion, laceration, atelectasis, and hemothorax definitely. Therefore, computed tomographic evaluation is needed for accurate evaluation of the injuries. In our knowledge, there are few reports about CT findings of blunt chest trauma, in our country, therefore we tried to fluid the characteristic CT findings in patients with blunt trauma. We analyzed the plain x-ray and CT image of 4 patients with blunt chest trauma. Location and morphology of lung parenchymal contusion and laceration, hemopneumothorax, chest wall injuries and location of chest tube. Lung parenchymal contusion was noted in 53 segments., of 16 patients infiltration(n=27 segment), and multiple nodular pattern was noted in 15 segment, pattern of consolidation along the lung periphery was seen in 11 segment. Laceration was noted in 18 lesion and most commonly located in paravertebral area(b=8). CT scan of chest in patient with blunt chest trauma, provides accurate information of the pattern of injuries, and localization, therefore, should be performed as possible

Chest-wall invading malignancies usually necessitate the resection of the respective part of the thoracic wall. Gore-Tex® is the material of choice that is traditionally used to repair thoracic defects. This material is well accepted by the recipient; however, though not rejected, it is an inert material and behaves like a 'foreign body' within the thoracic wall. By contrast, there are materials that have the potential to physiologically integrate into the host, and these materials are currently under in vitro and also in vivo investigation. These materials offer a gradual but complete biodegradation over time, and severe adverse inflammatory responses can be avoided. Here, we present a novel material that is a biodegradable nanocomposite based on poly-lactic-co-glycolic acid and amorphous calcium phosphate nanoparticles in comparison to the traditionally employed Gore-Tex® being the standard for chest-wall replacement. On a mouse model of thoracic wall resection, that resembles the technique and localization applied in humans, poly-lactic-co-glycolic acid and amorphous calcium phosphate nanoparticles and Gore-Tex® were implanted subcutaneously and additionally tested in a separate series as a chest-wall graft. After 1, 2, 4 and 8 weeks cell infiltration into the respective materials, inflammatory reactions as well as neo-vascularization (endothelial cells) were determined in six different zones. While Gore-Tex® allowed for cell infiltration only at the outer surface, electrospun poly-lactic-co-glycolic acid and amorphous calcium phosphate nanoparticles were completely penetrated by infiltrating cells. These cells were composed mainly by macrophages, with only 4% of giant cells and lymphocytes. Total macrophage count increased by time while the number of IL1-β-expressing macrophages decreased, indicating a protective state towards the graft. As such, poly-lactic-co-glycolic acid and amorphous calcium phosphate nanoparticles seem to develop ideal

Angiosarcoma of the chest wall is a very rare tumor and it is difficult to radiologically differentiate this tumor from other malignant tumors. Chronic tuberculous empyema is a predisposing factor that has been associated with angiosarcoma. We report here on a case of a 66-year-old man with angiosarcoma that arose in the chest wall. Computed tomography (CT) demonstrated a heterogeneous enhancing mass in the chest wall with calcified pleural thickening and multiple pulmonary nodules with the halo sign, which all indicated the presence of sarcoma with hypervascular metastases

Diagnostic problems in chest injuries (angiography)

Roentgenography is the simplest and most reliable means to arrive at the diagnosis of chest injury. General roentgenograms are difficult to interpret as they tend to be technically imperfect. Fractures, emphysema, pneumothorax, accumulation of fluid can usually be ascertained directly; but the traumatic origin of changes in the pulmonary parenchyma or of an enlarged heart shadow cannot be reliably deduced from the X-ray appearance. It may provide some differential-diagnostic information but the correct interpretation of the findings depends on further observation. In 6-7% of severe chest trauma with vascular injuries and rupture of the diaphragm angiography is indicated. The evidence to be obtained from chest radiography should not be overestimated: fractures of ribs are sometimes overlocked, even by the expert; parenchymatous lesions may manifest themselves as shadows but their nature remains obscure until they have been related to the clinical and subsequent radiological findings. The same applies to rupture of the diaphragm, bronchi or vessels, if only the immediate posttraumatic roentgenographs are examined. A tent-shaped heart shadow is considered characteristic of the presence of fluid in the pericardium; this is valid only for chronic hydropericardium, but not for the potentially fatal cardiac tamponade; if the pericardium has lost its elasticity a haemorrhage of not more than 150 ml may prove fatal. Nor does the roentgenogram provide information about pulmonary function. Especially in cases of pulmonary shock minor changes in the chest roentgenogram may give a false sense of security when, in fact, blood gas analyses show that a life-endangering situation has developed. The radiologist who is aware of the limitations of the method will derive maximum diagnostic benefit from a chest angiography. No other method is capable of supplying information of such great importance in such a short time. (orig.) [de

This study radiographically examined the changes in the chest walls of patients with pectus excavatum (PE) after Nuss bar removal, to define the deformation caused by the bar and stabilizer. In the first part of the study, we compared the changes in chest radiographs of patients with PE to a preoperation PE control group. In the second part, we used multislice computed tomography (CT) scans to provide three-dimensional reconstructions with which to evaluate the changes to the thoracic wall. Part 1 From June 2006 to August 2011, 1,125 patients with PE who had posteroanterior chest radiographs taken before undergoing the Nuss procedure at four hospitals were enrolled as a preoperative control group. At the same time, 203 patients who had the bar removed were enrolled as the study group. The maximum dimensions of the outer boundary of the first to ninth rib pairs (R1-R9, rib pair width), chest height, and chest width were measured. Part 2 Thirty-one consecutive patients with PE (20 males and 11 females) who underwent Nuss bar removal were evaluated 7 to 30 days after operation. During this period, a further 34 patients with PE who had undergone CT imaging before bar insertion were evaluated and compared with the postoperative group. Part 1 The width of the lower ribs (R4-R9) after bar removal was significantly less than in the age-matched controls. The ribs adjacent to the bar (R5-R7) showed the greatest restriction. The width of the upper ribs (R1-R3) 2 to 3 years after bar placement did not differ significantly from the controls. Patients who were operated on after 10 years of age had less of a restrictive effect. Three years of bar placement resulted in more restriction than a 2-year period, particularly in patients younger than 10 years old. Part 2: A significant constriction of the chest wall was observed in 13 patients after removal of the Nuss bar. Constriction at ribs 5 to 8 was found to be present adjacent to the site of bar insertion. However

The risk factors for mortality following blunt chest wall trauma have neither been well established or summarised. To summarise the risk factors for mortality in blunt chest wall trauma patients based on available evidence in the literature. A systematic review of English and non-English articles using MEDLINE, EMBASE and the Cochrane Library from their introduction until May 2010. Additional studies were identified by hand-searching bibliographies and contacting relevant clinical experts. Grey literature was sought by searching abstracts from all Emergency Medicine conferences. Broad search terms and inclusion criteria were used to reduce the number of missed studies. A two step study selection process was used. All published and unpublished observational studies were included if they investigated estimates of association between a risk factor and mortality for blunt chest wall trauma patients. A two step data extraction process using pre-defined data fields, including study quality indicators. Each study was appraised using a previously designed quality assessment tool and the STROBE checklist. Where sufficient data were available, odds ratios with 95% confidence intervals were calculated using Mantel-Haenszel method for the risk factors investigated. The I(2) statistic was calculated for combined studies in order to assess heterogeneity. Age, number of rib fractures, presence of pre-existing disease and pneumonia were found to be related to mortality in 29 identified studies. Combined odds ratio of 1.98 (1.86-2.11, 95% CI), 2.02 (1.89-2.15, 95% CI), 2.43 (1.03-5.72, 95% CI) and 5.24 (3.51-7.82) for mortality were calculated for blunt chest wall trauma patients aged 65 years or more, with three or more rib fractures, pre-existing conditions and pneumonia respectively. The risk factors for mortality in patients sustaining blunt chest wall trauma were a patient age of 65 years or more, three or more rib fractures and the presence of pre-existing disease especially

Factors Associated with ICU Admission following Blunt Chest Trauma

Full Text Available Background. Blunt chest wall trauma accounts for over 10% of all trauma patients presenting to emergency departments worldwide. When the injury is not as severe, deciding which blunt chest wall trauma patients require a higher level of clinical input can be difficult. We hypothesized that patient factors, injury patterns, analgesia, postural condition, and positive airway pressure influence outcomes. Methods. The study population consisted of patients hospitalized with at least 3 rib fractures (RF and at least one pulmonary contusion and/or at least one pneumothorax lower than 2 cm. Results. A total of 140 patients were retrospectively analyzed. Ten patients (7.1% were admitted to intensive care unit (ICU within the first 72 hours, because of deterioration of the clinical conditions and gas exchange with worsening of chest X-ray/thoracic ultrasound/chest computed tomography. On univariable analysis and multivariable analysis, obliged orthopnea (p=0.0018 and the severity of trauma score (p<0.0002 were associated with admission to ICU. Conclusions. Obliged orthopnea was an independent predictor of ICU admission among patients incurring non-life-threatening blunt chest wall trauma. The main therapeutic approach associated with improved outcome is the prevention of pulmonary infections due to reduced tidal volume, namely, upright postural condition and positive airway pressure.

The risk of a wound dehiscence requiring chest wall port explant in patients treated with bevacizumab is inversely proportional to the interval between bevacizumab administration and port placement. There is significantly higher risk of wound dehiscence when the interval between bevacizumab administration and chest wall port placement is less than 14 days.

Anterior chest wall tuberculous abscess: a case report

Directory of Open Access Journals (Sweden)

Papavramidis Theodossis S

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.

Multidetector computed tomography (MDCT) characterised by speed and precision is increasingly accessible in emergency wards. The aim of our study was to determine the most common injuries to the chest region, as well as type associated extrathoracic injuries, and the treatment outcome. This prospective study included 61 patients with blunt trauma who were submitted to computed tomography (CT) of the thorax. The number of injuries was evaluated by organs and organ systems of the chest. The cause of the injury, the length and the outcome of the treatment, and the presence of injuries in other regions were assessed. Chest injuries were associated with injuries to other regions in 80.3% cases, predominantly injuries to extremities or pelvic bones in 54.1% cases, followed by head injuries in 39.3% patients. Associated thoracic injuries were present in 90.9% of patients with lethal outcome. Lung parenchymal lesions, pleural effusions and rib fractures were the most common injuries affecting 77.1%, 65.6% and 63.9% of the cases, respectively. Blunt chest trauma is a significant problem affecting predominantly males in their forties and it is usually caused by a motor vehicle accident. In case of pneumomediastinum or mediastinal haematoma, the use of 3D reconstructions is advised for diagnosing possible tracheobronchial ruptures and thoracic aorta injuries. Increased resolution of CT scanners yielded a large number of findings that are occult on radiography, especially in the event of lung parenchymal and pleural injuries. However, none imaging modality can replace surgical judgement.

To determine the value of high-resolution MRI in pleural and chest wall diseases, the normal and pathologic costal pleura and adjacent chest wall between paravertebral and the axillar region were examined with contrast enhanced high-resolution T 1 -weighted MRI images using a surface coil. Normal anatomy was evaluated in 5 healthy volunteers and a normal specimen of the thoracic wall, and correlation was made with corresponding HR-CT and histologic sections. CT-proved focal and diffuse changes of the pleura and the chest wall in 36 patients underwent HR-MRI, and visual comparison of MRI and CT was done retrospectively. Especially sagittal T 1 -weighted HR-MRI images allowed accurate delineation of the peripleural fat layer (PFL) and the innermost intercostal muscle (IIM), which served as landmarks of the intact inner chest wall. PFL and IIM were well delineated in 3/4 patients with tuberculous pleuritis, and in all 7 patients with non-specific pleuritis, as opposed to impairment of the PFL and/or the IIM, which was detected in 15/18 malignancies as a pattern of malignant chest wall involvement. In one case of tuberculous pleural empyema with edema of the inner chest wall HR-MRI produced false positive diagnosis of malignant disease. HR-MRI images improved non-invasive evaluation of pleural and chest wall diseases, and allowed for differentiation of bengin and malignant changes. (orig./MG) [de

Cardiovascular injuries after trauma present with high mortality. The aim of the study was to present our experience in cardiac and great vessel injuries after chest trauma. During the 10-year period, 104 patients with cardiac (n=94) and great vessel (n=10) injuries presented to our hospital. The demographic data, mechanism of injury, location of injury, other associated injuries, timing of surgical intervention, surgical approach, and clinical outcome were reviewed. Eighty-eight (84.6%) males presented after chest trauma. The mean age of the patients was 32.5±8.2 years (range: 12-76). Penetrating injuries (62.5%) were the most common cause of trauma. Computed tomography was performed in most cases and echocardiography was used in some stable cases. Cardiac injuries mostly included the right ventricle (58.5%). Great vessel injuries involved the subclavian vein in 6, innominate vein in 1, vena cava in 1, and descending aorta in 2 patients. Early operations after admission to the emergency were performed in 75.9% of the patients. Thoracotomy was performed in 89.5% of the patients. Operative mortality was significantly high in penetrating injuries (p=0.01). Clinicians should suspect cardiac and great vessel trauma in every patient presenting to the emergency unit after chest trauma. Computed tomography and echocardiography are beneficial in the management of chest trauma. Operative timing depends on hemodynamic status, and a multidisciplinary team approach improves the patient's prognosis.

To assess the acute effects of air stacking on cough peak flow (CPF) and chest wall compartmental volumes of persons with amyotrophic lateral sclerosis (ALS) versus healthy subjects positioned at 45° body inclination. Cross-sectional study with a matched-pair design. University hospital. Persons (N=24) with ALS (n=12) and age-matched healthy subjects (n=12). CPF, chest wall compartmental inspiratory capacity, chest wall vital capacity, chest wall tidal volume and operational volumes, breathing pattern, and percentage of contribution of the compartments to the inspired volume were measured by optoelectronic plethysmography. Compared with healthy subjects, significantly lower CPF (P=.007), chest wall compartmental inspiratory capacity (Pprotocol in the healthy subjects, mainly because of end-inspiratory (P<.001) and abdominal volumes (P=.008). No significant differences were observed in percentage of contribution of the compartments to the inspired volume and end-expiratory volume of both groups. No significant differences were found in chest wall tidal volume, operational volume, and breathing pattern in persons with ALS. Air stacking is effective in increasing CPF, chest wall compartmental inspiratory capacity, and chest wall vital capacity of persons with ALS with no hyperinflation. Differences in compartmental volume contributions are probably because of lung and chest wall physiological changes. Copyright © 2016 American Congress of Rehabilitation Medicine.

Nowadays, in chest wall reconstruction prosthetic materials are generally used. However, the rejections of prosthetic materials and infections frequently occur in chest wall reconstruction, especially after radiotherapy or resection that is performed due to infections. We used 10 mongrel dogs and performed resections of 8 cm diameter on their chest walls. In the reconstruction of these defects, in five of the subjects, we used two free rib grafts with periosteum to be resected from the contralateral side and in other five subjects, we used free rib grafts without periosteum. After this experimental study, sternal resection was performed in a 24-year-old man because of sternal osteomyelitis. First to obtain rib grafts with periosteum, partial resection was performed to 5th, 7th, and 9th ribs of the lateral left side. After, total sternal resection, end to end anastomosis was performed to the 2nd, 3rd, 4th and 5th anterior ends of the ribs. Autogeneous rib grafts were found to be enough to provide chest wall stabilization. The contralateral autogeneous free rib grafts can successfully be used in reconstruction of wide chest wall defects. This method is found to be effective and sufficient to prevent infection, rejection and to provide stabilization.

Imaging plays an essential part of chest trauma care. By definition, the employed imaging technique in the emergency setting should reach the correct diagnosis as fast as possible. In severe chest blunt trauma, multidetector computer tomography (MDCT) has become part of the initial workup, mainly due to its high sensitivity and diagnostic accuracy of the technique for the detection and characterization of thoracic injuries and also due to its wide availability in tertiary care centers. The aim of this paper is to review and illustrate a spectrum of characteristic MDCT findings of blunt traumatic injuries of the chest including the lungs, mediastinum, pleural space, and chest wall.

Traditionally chest tubes are set to -20 cm H 2 O wall suctioning until removal to facilitate drainage of blood, fluid, and air from the pleural or mediastinal space in patients after open heart surgery. However, no clear evidence supports using wall suction in these patients. Some studies in patients after pulmonary surgery indicate that using chest tubes with a water seal is safer, because this practice decreases duration of chest tube placement and eliminates air leaks. To show that changing chest tubes to a water seal after 12 hours of wall suction (intervention) is a safe alternative to using chest tubes with wall suction until removal of the tubes (usual care) in patients after open heart surgery. A before-and-after quality improvement design was used to evaluate the differences between the 2 chest tube management approaches in chest tube complications, output, and duration of placement. A total of 48 patients received the intervention; 52 received usual care. The 2 groups (intervention vs usual care) did not differ significantly in complications (0 vs 2 events; P = .23), chest tube output (H 1 = 0.001, P = .97), or duration of placement (median, 47 hours for both groups). Changing chest tubes from wall suction to water seal after 12 hours of wall suction is a safe alternative to using wall suctioning until removal of the tubes. ©2017 American Association of Critical-Care Nurses.

This study examined the effect of sitting posture on regional chest wall shape in three dimensions, chest wall motion (measured with electromagnetic motion analysis system), and relative contributions of the ribcage and abdomen to tidal volume (%RC/V(t)) (measured with inductance plethysmography) in 7 healthy volunteers. In seven seated postures, increased dead space breathing automatically increased V(t) (to 1.5 V(t)) to match volume between conditions and study the effects of posture independent of volume changes. %RC/V(t) (pplane changes in sitting posture alter three-dimensional ribcage configuration and chest wall kinematics during breathing, while maintaining constant respiratory function.

The operative indications for rib fracture repair have been a matter of debate. However, several reports have suggested that flail chest, pain on respiration, and chest deformity/defect are potential conditions for rib fracture repair. We describe our experience of rib fixation in a patient with severe chest deformity due to multiple rib fractures. A 70-year-old woman was admitted with right-sided multiple rib fractures (2nd to 7th) and marked chest wall deformity without flailing caused by an automobile accident. Collapse of the chest wall was observed along the middle anterior axillary line. At 11 days after the injury, surgery was performed to repair the chest deformity, as it was considered to pose a risk of restrictive impairment of pulmonary function or chronic intercostal pain in the future. Operative findings revealed marked displacement of the superior 4 ribs, from the 2nd to the 5th, and collapse of the osseous chest wall towards the thoracic cavity. After exposure of the fracture regions, ribs fixations were performed using rib staplers. The total operation time was 90 minutes, and the collapsed portion of the chest wall along the middle anterior axillary line was reconstructed successfully.

Reconstruction of the radiation-damaged chest wall

Arnold, P.G.; Pairolero, P.C.

1989-01-01

In the patient with a radiation ulcer of the chest wall, the first question is whether the lesion contains persistent or recurrent cancer. It is also important to determine whether any other local problems such as mediastinal abscess may interfere with the reconstruction. Whether or not cancer is present, all nonviable tissue must be removed. If cancer is not present, and a partial thickness of the chest remains, the authors prefer transposition of the greater omentum for repair. If cancer is present, the physiologic defect resulting from cancer resection and wound debridement is far more severe, and a muscle or musculocutaneous flap usually is appropriate. The pectoralis major, latissimus dorsi, external oblique, rectus abdominis, and trapezius muscles have been utilized; the authors most often use the pectoralis or latissimus muscles. 27 references

This prospective study evaluates the early result of patients with massive chest wall tumors treated by extended resection and reconstruction using Prolene or Marlex mesh-enforced with Poly Methyl Methacrylate Bone Cement (PMMC) prosthesis. Material and Methods: This surgery was performed on 40 patients with a mean age of 45±18 (12-62) at the Department of Surgery, National Cancer Institute, Cairo University between 1998-2001. Primary chest wall tumors were the indications of surgery in 42.5%, while secondary involvement extending from other sites principally breast cancer were the indications for 57.5%. In 85% of patients more than 3 ribs were involved by tumors and lesions were more than 10 cm in the greatest dimension in 50% of cases. Resection involved sternum in 15 (37.5%) cases and in 45% of cases complete extensive rib resections extended between costovertebral junctions and the costochondral junctions were performed. Additional resections of nearby organs were needed in 20 (50%) of cases including partial lung resection in 14 cases, partial vertebral resection in 3 cases and diaphragm resection for 3 cases. Immediate bony reconstruction by inserting Prolene or Marlex mesh-enforced with Poly Methyl Methacrylate Bone Cement (PMMC) prosthesis to the resulting chest wall defect was performed in 36 cases, whereas, 4 cases had delayed reconstruction. Primary simple soft tissue closure was sufficient for 37.5% of patients; whereas 35% were covered by local rotational flap and 27.5% needed myocutaneous flaps. No patient with this immediate reconstruction needed ventilatory support or tracheostomy and flail chest was not noticed ICU stay was markedly reduced; whereas 85% required less than 7 days. Immediate post operative (40 days) complications were found in 14 patients (35%) and cases with additional lung resection had more complication rate than others (64% vs 19%). Infection occurred in 3 patients and conservative treatment for 3-4 weeks using frequent

Most patients with penetrating chest injuries benefit from early treatment with chest tube drainage or surgery. Although penetrating chest injury is not uncommon, few descriptive studies are published, especially in Europe. The aim of this study was to review our experience and further improve our management of penetrating chest injuries in a level I trauma center in the Netherlands. All patients with penetrating chest injury between August 2004 and December 2012 were included. Demographics, mechanism of injury, physiological parameters, Injury Severity Scores (ISS), surgical and non-surgical treatment, length of intensive care unit (ICU) stay, length of hospital stay (LOS), complications and rate of mortality were collected. A total of 159 patients were analyzed. Patients included 116 (73 %) stab wounds and 34 (21 %) gunshot wounds. In 27 patients (17 %), cardiac injury was seen. The mean ISS was 12. Almost half of all patients (49 %) were treated with only chest tube drainage. Alternatively, surgical treatment was performed in 24 % of all cases. Anterolateral incision was most frequently used to gain access to the thoracic cavity. The mean LOS was 9 days. Among all patients, 17 % were admitted to the ICU with a mean stay of 3 days. In 18 (11 %) patients, one or more complications occurred. The 30-day mortality was 7.5 %. Patients presenting with penetrating chest injury are not uncommon in the Netherlands and can mostly be treated conservatively. In one-fourth of the patients, surgical treatment is performed. A structural and vigorous approach is needed for good clinical outcome.

We report on the impact of a thermoplastic immobilization system on intra- and interfraction motion for patients undergoing breast or chest wall radiation therapy. Patients for this study were treated using helical tomotherapy. All patients were immobilized using a thermoplastic shell extending from the shoulders to the ribcage. Intrafraction motion was assessed by measuring maximum displacement of the skin, heart, and chest wall on a pretreatment 4D computed tomography, while inter-fraction motion was inferred from patient shift data arising from daily image guidance procedures on tomotherapy. Using thermoplastic immobilization, the average maximum motion of the external contour was 1.3 ± 1.6 mm, whereas the chest wall was found to be 1.6 ± 1.9 mm. The day-to-day setup variation was found to be large, with random errors of 4.0, 12.0, and 4.5 mm in the left-right, superior-inferior, and anterior-posterior directions, respectively, and the standard deviations of the systematic errors were found to be 2.7, 9.8, and 4.1 mm. These errors would be expected to dominate any respiratory motion but can be mitigated by daily online image guidance. Using thermoplastic immobilization can effectively reduce respiratory motion of the chest wall and external contour, but these gains can only be realized if daily image guidance is used.

Volume Modulated Arc Therapy (VMAT for pulmonary Stereotactic Body Radiotherapy (SBRT in patients with lesions in close approximation to the chest wall

Full Text Available Chest wall pain and discomfort has been recognized as a significant late effect of radiation therapy in historical and modern treatment models. Stereotactic Body Radiotherapy (SBRT is becoming an important treatment tool in oncology care for patients with intrathoracic lesions. For lesions in close approximation to the chest wall including lesions requiring motion management, SBRT techniques can deliver high dose to the chest wall. As an unintended target of consequence, there is possibility of generating significant chest wall pain and discomfort as a late effect of therapy. The purpose of this paper is to evaluate the potential role of Volume Modulated Arc Therapy (VMAT technologies in decreasing chest wall dose in SBRT treatment of pulmonary lesions in close approximation to the chest wall.Ten patients with pulmonary lesions of various sizes and topography in close approximation to the chest wall were selected for retrospective review. All volumes including target, chest wall, ribs, and lung were contoured with maximal intensity projection maps and four-dimensional computer tomography planning. Radiation therapy planning consisted of static techniques including Intensity Modulated Radiation Therapy compared to VMAT therapy to a dose of 60Gy in 12Gy fractions. Dose volume histogram to rib, chest wall, and lung were compared between plans with statistical analysis.In all patients dose and volume were improved to ribs and chest wall using VMAT technologies compared to static field techniques. On average, volume receiving 30Gy to the chest wall was improved by 72%;the ribs by 60%. In only one patient did the VMAT treatment technique increase pulmonary volume receiving 20Gy (V20.VMAT technology has potential of limiting radiation dose to sensitive chest wall regions in patients with lesions in close approximation to this structure. This would also have potential value to lesions treated with SBRT in other body regions where targets abut critical

Cardiorespiratory effects of inelastic chest wall restriction.

We examined the effects of chest wall restriction (CWR) on cardiorespiratory function at rest and during exercise in healthy subjects in an attempt to approximate the cardiorespiratory interactions observed in clinical conditions that result in restrictive lung and/or chest wall changes and a reduced intrathoracic space. Canvas straps were applied around the thorax and abdomen so that vital capacity was reduced by >35%. Data were acquired at rest and during cycle ergometry at 25 and 45% of peak workloads. CWR elicited significant increases in the flow-resistive work performed on the lung (160%) and the gastric pressure-time integral (>400%) at the higher workload, but it resulted in a decrease in the elastic work performed on the lung (56%) compared with control conditions. With CWR, heart rate increased and stroke volume (SV) fell, resulting in >10% fall in cardiac output at rest and during exercise at matched workloads (P < 0.05). Blood pressure and catecholamines were significantly elevated during CWR exercise conditions (P < 0.05). We conclude that CWR significantly impairs SV during exercise and that a compensatory increase in heart rate does not prevent a significant reduction in cardiac output. O(2) consumption appears to be maintained via increased extraction and a redistribution of blood flow via sympathetic activation.

Purpose/Objective: Since 1980 electron arc irradiation of the postmastectomy chest wall has been the preferred technique for patients with advanced breast cancer at the our institution. Here we report the results of this technique in 150 consecutive patients from 1980 to 1994. Materials and Methods: Thoracic computerized tomography was used to determine internal mammary lymph node depth and chest wall thickness, and for computerized dosimetry calculations in all patients. Total doses of 45-50 Gy in 5 to 5 (1(2)) weeks were delivered to the chest wall and internal mammary lymph nodes via electron arc and, in most cases, supraclavicular and axillary nodes were treated with a matching photon field. Patients were assessed for acute and late radiation changes, local and distant control of disease, and survival. The 10 most recently treated patients were censored for disease progression, survival, and late effects calculations, thus giving a mean follow up of 49 months and a median of 33 months. All patients had advanced disease: T stages 1, 2, 3, and 4 represented 21%, 39%, 21% and 19% of the study population, with a mean number of positive axillary lymph nodes of 6.5 (0-29). Analysis was performed according to adjuvant status (no residual disease, n = 90), residual disease (positive margin, n = 15, and primary radiation, n = 2), or recurrent disease (n = 33). Results: Acute radiation reactions were generally mild and self limiting. 27% of patients developed moist desquamation, and 32% had brisk erythema. Actuarial 5 year local control, freedom from distant failure and overall survival was 91%, 64%, and 67% in the adjuvant group; 84%, 50%, and 53% in the residual disease group; and 63%, 34%, and 30% in the recurrent disease group, respectively. In univariate cox regressions, the number of positive lymph nodes was predictive for local failure in the adjuvant group (p<0.037). Chronic complications were minimal with 10% of patients having arm edema, 15% hyperpigmentation

Pediatric trauma is commonly encountered in the emergency department, and trauma to the head, chest, and abdomen may be a source of significant morbidity and mortality. As children have unique thoracic anatomical and physiological properties, they may present with diagnostic challenges that the emergency clinician must be aware of. This review examines the effects of blunt trauma to the pediatric chest, as well as its relevant etiologies and associated mortality. Diagnostic and treatment options for commonly encountered injuries such as pulmonary contusions, rib fractures, and pneumothoraces are examined. Additionally, this review discusses rarely encountered--yet highly lethal--chest wall injuries such as blunt cardiac injuries, commotio cordis, nonaccidental trauma, and aortic injuries.

Masculine Chest-Wall Contouring in FtM Transgender: a Personal Approach.

Lo Russo, Giulia; Tanini, Sara; Innocenti, Marco

2017-04-01

Chest-wall contouring surgery is one of the first steps in sexual reassignment in female-to-male (FtM) transsexuals that contributes to strengthening of the self-image and facilitates living in the new gender role. The main goal is to masculinize the chest by removing the female contour. Chest contour, scar placement, scar shape, scar length, nipple-areola position, nipple size and the areola size are the key points. Between July 2013 and June 2016, 25 FtM transgender patients underwent surgical procedures to create a masculine chest-wall contour. In our study, we just considered 16 patients who have undergone chest surgery with the double incision method. The patients' survey revealed a high satisfaction rate with the aesthetic result. In our group, no complications occurred, and two patients have undergone supplementary surgery for axillary dog-ear revision and nipple reconstruction. The authors propose a new technical approach and indications for FtM transgender patients' surgery. A longer scar that emphasizes the pectoralis muscle, a smaller nipple and a resized and refaced areola are the key points of our technique to give a masculine appearance to the chest. The scars are permanent, but most of them will fade and the patients are enthusiastic with their new "male" chest appearance. The high level of satisfaction, the great aesthetic result and the low rate of complications suggest to us the use of this technique in medium- and large-size breasts.

2014-02-01

Chest wall deformities/defects and chest wall resections, as well as complex rib fractures require reconstruction with various prosthetic materials to ensure the basic functions of the chest wall. Titanium provides many features that make it an ideal material for this surgery. The aim is to present our initial results with this material in several diseases. From 2008 to 2012, 14 patients were operated on and titanium was used for reconstruction of the chest wall. A total of 7 patients had chest wall tumors, 2 with sternal resection, 4 patients with chest wall deformities/defects and 3 patients with severe rib injury due to traffic accident. The reconstruction was successful in all cases, with early extubation without detecting problems in the functionality of the chest wall at a respiratory level. Patients with chest wall tumors including sternal resections were extubated in the operating room as well as the chest wall deformities. Chest trauma cases were extubated within 24h from internal rib fixation. There were no complications related to the material used and the method of implementation. Titanium is an ideal material for reconstruction of the chest wall in several clinical situations allowing for great versatility and adaptability in different chest wall reconstructions.

Full Text Available Introduction: Hydatid cyst is a parasitic disease caused by Echinococci. The most commonly affected organ is liver, followed by lungs. Hydatid disease of the chest wall is extremely rare. The aim of this study is to report a case of chest wall Hydatid cyst with literature review. A 20-year-old pregnant lady presented with left hypochondrial and lower chest painful swelling. There was 10 × 15 centimeters, tender mass with features suggestive of abscess. The patient refused every sort of radiological examination. Under general anesthesia, oblique incision was done, on opening, clear fluid came out, with deep incision pus-like fluid and many daughter cysts drained. Complete evacuation of the cyst was done with closure of the residual cavity. The patient refused chemoprophylaxis because of her pregnancy. Conclusion: primary chest wall Hydatid cyst is a very rare disease in endemic areas. Mass and pain are the most common presentation. Excision under general anesthesia is main modality of treatment.

A 79-year-old female with breast carcinoma undergoing a classical Halsted radical mastectomy followed by irradiation (total; 180 Gy) 20 years before developed a left anterior chest wall ulcer. The ulcer was 10.0 x 8.0 cm in size with osteolysis of 3rd, 4th and 5th ribs, exposed pericardium, and parietal pleura with a pleuro-cutaneous fistula. After thorough debridement, an omental pedicle flap was transposed onto the chest wall defect and subsequently covered using a split-skin graft. The omental pedicle flap was 90% effective in covering the pericardial defect and resulted in a complete closure of the pleuro-cutaneous fistula. This report emphasises that an omental pedicle flap is effective in the treatment of radio-necrosis of the chest wall and also stresses the importance of judging the extent of debridement of radio-necrotic tissue.

Full Text Available AimThe purpose of this study is to describe the development of an external 3-dimensional (3D scanner as a noninvasive method for imaging chest wall deformities. It allows objective assessment, reconstruction of the area of interest, and evaluation of the severity of the deformity by using external indexes.External 3D scanning systemThe OrtenBodyOne scanner (Orten, Lyon, France uses depth sensors to scan the entire 3D external body surface of a patient. The depth sensors combine structured light with two classic computer vision techniques: depth from focus and depth from stereo. The data acquired are processed and analyzed using the Orten-Clinic software.Materials and methodsTo investigate the performance of the device, a preliminary prospective study (January 2015–March 2016 was carried out in patients attending our hospital chest wall deformities unit. In total, 100 patients (children and young adults with pectus excavatum or pectus carinatum, treated by surgery or non-operative methods were included. In patients undergoing non-operative treatment, external 3D scanning was performed monthly until complete correction was achieved. In surgically treated patients, scanning was done before and after surgical correction. In 42 patients, computed tomography (CT was additionally performed and correlations between the Haller index calculated by CT and the external Haller index using external scanning were investigated using a Student’s test (r = 0.83.ConclusionExternal scanning is an effective, objective, radiation-free means to diagnose and follow-up patients with chest wall deformities. Externally measured indexes can be used to evaluate the severity of these conditions and the treatment outcomes.

Of the conventional P-A and A-P chest films which have been studied, many roentgenologic signs suggested for chest trauma. In the present study, an effort was designated to further clarify the x-ray findings of the nonpenetrating extracardiac chest injuries and to observe the x-ray findings being a leading maneuver of surgical procedure. Fat embolism and shock lung must be kept in mind on follow up films. The results thus obtained are summarized as follows; 1. Most of cases are visualized between the age of 10 and 50 and more common in male. 2. The denoting rib fracture, hemopneumothorax, and lung contusion are direct roentgenologic signs. 3. In case of serious result which showed pulmonary edema pattern on conventional chest films, we thought fat embolism or shock lung to be the cause of death.

Traumatic pulmonary pseudocyst (TPP) is a rare complication of blunt chest trauma and closely related with severe injury. However, it has been poorly documented. We present a retrospective review of TPP cases treated at our hospital. The medical records and chest computed tomography scans of patients with TPP treated from January 2010 to December 2013 were retrospectively studied. A total of 978 patients underwent chest computed tomography for blunt chest trauma during the study period, and 81 (8.3%) had a total of 150 TPPs. The most common mechanism of injury was being struck by a motorized vehicle (n = 25, 30.9%). The mean (SD) Injury Severity Score (ISS) of the 81 patients was 33.2 (11.4). The prevalence of TPP was higher in younger patients (p = 0.011), but the total number of fractured ribs was significantly lower (p = 0.001). In a subgroup analysis performed according to pseudocyst location, the intraparenchymal group had more severe injuries than the subpleural group (ISS, 23.3 vs. 32.4, p chest Abbreviated Injury Scale [AIS] score, 3.4 vs. 4.0, p chest trauma was 8.3% and was higher in those struck by a vehicle and younger patients. Intraparenchymal pseudocyst was found to be related to more severe injuries. TPP was a self-limiting condition that does not require specific treatment. Prognostic/epidemiologic study, level IV.

We present a structured light system to dynamically measure human chest wall motion for respiratory volume estimation. Based on a projection of an encoded color pattern and a few active markers attached to the trunk, respiratory volumes are obtained by evaluating the 3-D topographic changes of the chest wall in an anatomically consistent measuring region during respiration. Three measuring setups are established: a single-sided illuminating-recording setup for standing posture, an inclined single-sided setup for supine posture, and a double-sided setup for standing posture. Results are compared with the pneumotachography and show good agreement in volume estimations [correlation coefficient: R>0.99 (Pvolume during the isovolume maneuver (standard deviationpulmonary functional differences between the diseased and the contralateral sides of the thorax, and subsequent improvement of this imbalance after drainage. These results demonstrate the proposed optical method is capable of not only whole respiratory volume evaluation with high accuracy, but also regional pulmonary function assessment in different chest wall behaviors, with the advantage of whole-field measurement.

2018-05-01

This study aimed to compare the diagnostic accuracy of NEXUS chest and Thoracic Injury Rule out criteria (TIRC) models in predicting the risk of intra-thoracic injuries following blunt multiple trauma. In this diagnostic accuracy study, using the 2 mentioned models, blunt multiple trauma patients over the age of 15 years presenting to emergency department were screened regarding the presence of intra-thoracic injuries that are detectable via chest x-ray and screening performance characteristics of the models were compared. In this study, 3118 patients with the mean (SD) age of 37.4 (16.9) years were studied (57.4% male). Based on TIRC and NEXUS chest, respectively, 1340 (43%) and 1417 (45.4%) patients were deemed in need of radiography performance. Sensitivity, specificity, and positive and negative predictive values of TIRC were 98.95%, 62.70%, 21.19% and 99.83%. These values were 98.61%, 59.94%, 19.97% and 99.76%, for NEXUS chest, respectively. Accuracy of TIRC and NEXUS chest models were 66.04 (95% CI: 64.34-67.70) and 63.50 (95% CI: 61.78-65.19), respectively. TIRC and NEXUS chest models have proper and similar sensitivity in prediction of blunt traumatic intra-thoracic injuries that are detectable via chest x-ray. However, TIRC had a significantly higher specificity in this regard. Copyright © 2018 Elsevier Ltd. All rights reserved.

2012-05-01

Full Text Available Abstract Background Severe chest wall injuries are potentially life-threatening injuries which require a standardized multidisciplinary management strategy for prevention of posttraumatic complications and adverse outcome. Case presentation We report the successful management of a 55-year old man who sustained a complete “bony disruption” of the thoracic cage secondary to an “all-terrain vehicle” roll-over accident. The injury pattern consisted of a bilateral “flail chest” with serial segmental rib fractures, bilateral hemo-pneumothoraces and pulmonary contusions, bilateral midshaft clavicle fractures, a displaced transverse sternum fracture with significant diastasis, and an unstable T9 hyperextension injury. After initial life-saving procedures, the chest wall injuries were sequentially stabilized by surgical fixation of bilateral clavicle fractures, locked plating of the displaced sternal fracture, and a two-level anterior spine fixation of the T9 hyperextension injury. The patient had an excellent radiological and physiological outcome at 6 months post injury. Conclusion Severe chest wall trauma with a complete “bony disruption” of the thoracic cage represents a rare, but detrimental injury pattern. Multidisciplinary management with a staged timing for addressing each of the critical injuries, represents the ideal approach for an excellent long-term outcome.

Hernandez, L A; Peevy, K J; Moise, A A; Parker, J C

High peak inspiratory pressures (PIP) during mechanical ventilation can induce lung injury. In the present study we compare the respective roles of high tidal volume with high PIP in intact immature rabbits to determine whether the increase in capillary permeability is the result of overdistension of the lung or direct pressure effects. New Zealand White rabbits were assigned to one of three protocols, which produced different degrees of inspiratory volume limitation: intact closed-chest animals (CC), closed-chest animals with a full-body plaster cast (C), and isolated excised lungs (IL). The intact animals were ventilated at 15, 30, or 45 cmH2O PIP for 1 h, and the lungs of the CC and C groups were placed in an isolated lung perfusion system. Microvascular permeability was evaluated using the capillary filtration coefficient (Kfc). Base-line Kfc for isolated lungs before ventilation was 0.33 +/- 0.31 ml.min-1.cmH2O-1.100g-1 and was not different from the Kfc in the CC group ventilated with 15 cmH2O PIP. Kfc increased by 850% after ventilation with only 15 cmH2O PIP in the unrestricted IL group, and in the CC group Kfc increased by 31% after 30 cmH2O PIP and 430% after 45 cmH2O PIP. Inspiratory volume limitation by the plaster cast in the C group prevented any significant increase in Kfc at the PIP values used. These data indicate that volume distension of the lung rather than high PIP per se produces microvascular damage in the immature rabbit lung.

Complex regional pain syndrome with associated chest wall dystonia: a case report

Directory of Open Access Journals (Sweden)

Schwartzman Robert J

2011-09-01

Full Text Available Abstract Patients with complex regional pain syndrome (CRPS often suffer from an array of associated movement disorders, including dystonia of an affected limb. We present a case of a patient with long standing CRPS after a brachial plexus injury, who after displaying several features of the movement disorder previously, developed painful dystonia of chest wall musculature. Detailed neurologic examination found palpable sustained contractions of the pectoral and intercostal muscles in addition to surface allodynia. Needle electromyography of the intercostal and paraspinal muscles supported the diagnosis of dystonia. In addition, pulmonary function testing showed both restrictive and obstructive features in the absence of a clear cardiopulmonary etiology. Treatment was initiated with intrathecal baclofen and the patient had symptomatic relief and improvement of dystonia. This case illustrates a novel form of the movement disorder associated with CRPS with response to intrathecal baclofen treatment.

To describe the association of bodybuilding abdominal exercise with the development of superficial sclerosing thrombophlebitis of the anterolateral thoracoabdominal wall. A single case study. University-affiliated regional community hospital. A 54-year-old man presented with an otherwise unremarkable past medical history 4 weeks after the start of left-sided chest discomfort. He had undergone orthopedic surgery of the right shoulder three months earlier. Two months after surgery, he had re-started bodybuilding with thoracoabdominal training. Soon thereafter, he noted a painful induration at the left side of his trunk. Doppler and duplex sonography revealed complete venous occlusion compatible with sclerosing thrombophlebitis leading to a palpable, subcutaneous, cord-like lesion on the left side of his trunk. Physical examination and routine laboratory findings were normal. The lesion spontaneously resolved over a course of 3 months. Mondor's disease of the subcutaneous veins of the chest wall which has been associated with breast or axillary surgery, malignant and systemic diseases can also appear in subjects performing intense thoracoabdominal exercise training. Although it requires only symptomatic therapy, physicians and therapists must be aware of the existence of this disease because, although benign and self-limiting, malignant and systemic diseases need to be ruled out.

CT analysis of pulmonary injuries from blunt chest trauma

International Nuclear Information System (INIS)

Konno, Shoko

1996-01-01

The purpose of this paper is to analyze the CT findings of pulmonary parenchymal injuries due to blunt chest trauma and to categorize CT findings on the basis of their outcome. The materials of this study consist of 62 patients who had pulmonary injuries on CT obtained within 6 hours after blunt chest trauma. CT findings were analysed with regards to the shape, size, and distribution of the lesions. Follow-up CT scans were obtained in 35 patients at intervals from 1 day to 1 month after the initial CT study. CT showed ill-defined opacities in 59 patients (64 lesions in the peripheral area and 95 in the non-peripheral area) and pulmonary nodules with or without cavitary lesions in 30 patients (7 lesions in the peripheral area and 31 in the non-peripheral area). Follow-up CT allowed the classification of these pulmonary injuries into 3 types; the non-peripheral, ill-defined opacities showing immediate clearing, nodules with or without cavitary lesions over 1 cm in diameter showing prolongation, and the peripheral ill-defined opacities adjacent to the thoracic cage, and small nodules with or without cavitary lesions within 1 cm in diameter, showing various courses. CT has marked advantage over plain chest radiographs not only in the detection rate but in accurate estimation of the prognosis of the lesions. (author)

Purpose: We investigate DIBH breast radiotherapy using the Real-time Position Management (RPM) system with the marker-block placed on the target breast or chest wall. Methods: We measured surface dose for three different RPM marker-blocks using EBT3 Gafchromic film at 0° and 30° incidence. A registration study was performed to determine the breast surface position that best correlates with overall internal chest wall position. Surface and chest wall contours from MV images of the medial tangent field were extracted for 15 patients. Surface contours were divided into three potential marker-block positions on the breast: Superior, Middle, and Inferior. Translational registration was used to align the partial contours to the first-fraction contour. Each resultant transformation matrix was applied to the chest wall contour, and the minimum distance between the reference chest wall contour and the transformed chest wall contour was evaluated for each pixel. Results: The measured surface dose for the 2-dot, 6-dot, and 4-dot marker-blocks at 0° incidence were 74%, 71%, and 77% of dose to dmax respectively. At 30° beam incidence this increased to 76%, 72%, and 81%. The best external surface position was patient and fraction dependent, with no consistent best choice. Conclusions: The increase in surface dose directly under the RPM block is approximately equivalent to 3 mm of bolus. No marker-block position on the breast surface was found to be more representative of overall chest wall motion; therefore block positional stability and reproducibility can be used to determine optimal placement on the breast or chest wall.

Full Text Available Primary infiltrating ductal carcinoma of the axillary breast is rare and has a high frequency of lymph node (LN involvement. We report a woman with primary infiltrating ductal carcinoma arising from the right axillary breast with metastasis to the contralateral chest wall. Excisional biopsy of the left chest wall nodule and the right axillary mass was carried out and both showed invasive ductal carcinomas histologically. The lesion of the right axillary mass arose from the breast tissue, rather than the LN. Further surgery proved the right axillary LN metastasis. After further review, a primary infiltrating ductal carcinoma of the right axillary breast with metastasis to axillary LNs and contralateral chest wall was diagnosed. The patient also received chemotherapy and radiation and there was no evidence of tumor recurrence after treatment. The present report demonstrated a rare case with uncommon manifestation. Lesions of uncertain origin around the periphery of the breast should be suspected for breast carcinoma.

2006-01-01

Purpose: To evaluate the role of chest radiography, single-slice CT and 16-row MDCT in the direct evidence of tracheobronchial injuries. Methods: Patients with acute tracheobronchial injury were identified from the registry of our level 1 trauma center during a 5-year period ending July 2005. Findings at chest radiograph and CT were compared to those shown at bronchoscopy. Results: Eighteen patients with tracheobronchial injury - three patients with cervical trachea injury, eight with thoracic trachea injury and seven with bronchial injury - were identified. Twelve patients had a blunt trauma (67%), six patients had a penetrating (iatrogenic) injury (33%). Chest radiograph directly identified the site of tracheal injury in four cases, showing overdistension of the endotracheal cuff in three cases and displacement of the endotracheal tube in one case. At the level of the bronchi, chest radiograph demonstrated only one injury. CT directly identified the site of tracheal injury in all the cases showing the overdistension of the endotracheal cuff at the level of the thoracic trachea (three cases), posterior herniation of the endotracheal cuff at the thoracic trachea (three cases), lateral endotracheal cuff herniation at the thoracic trachea (one case), tracheal wall discontinuity at the cervical (one case) and at the thoracic trachea (one case) and displacement of endotracheal tube at the cervical trachea (two cases). At the level of the bronchi, CT correctly showed the site of injury in six case including: discontinuity of the left main bronchial wall (two cases), the 'fallen lung' sign (one case), right main bronchial wall enlargement (one case), discontinuity of the right middle bronchial wall (two cases). In one case, CT showed just direct 'air leak' at the level of the carina suggesting main bronchus injury. This finding was confirmed by bronchoscopy. Conclusion: Chest radiograph was helpful for the assessment of iatrogenic tracheal injuries. CT detected the site

As 3D printing technology emerge, there is increasing demand for a more customizable implant in the repair of chest-wall bony defects. This article aims to present a custom design and fabrication method for repairing bony defects of the chest wall following tumour resection, which utilizes three-dimensional (3D) printing and rapid-prototyping technology. A 3D model of the bony defect was generated after acquiring helical CT data. A customized prosthesis was then designed using computer-aided design (CAD) and mirroring technology, and fabricated using titanium-alloy powder. The mechanical properties of the printed prosthesis were investigated using ANSYS software. The yield strength of the titanium-alloy prosthesis was 950 ± 14 MPa (mean ± SD), and its ultimate strength was 1005 ± 26 MPa. The 3D finite element analyses revealed that the equivalent stress distribution of each prosthesis was unifrom. The symmetry and reconstruction quality contour of the repaired chest wall was satisfactory. No rejection or infection occurred during the 6-month follow-up period. Chest-wall reconstruction with a customized titanium-alloy prosthesis is a reliable technique for repairing bony defects.

Unnecessary diagnostic imaging leads to higher costs, longer emergency department stays, and increased patient exposure to ionizing radiation. We sought to prospectively derive and validate two decision instruments (DIs) for selective chest computed tomography (CT) in adult blunt trauma patients. From September 2011 to May 2014, we prospectively enrolled blunt trauma patients over 14 y of age presenting to eight US, urban level 1 trauma centers in this observational study. During the derivation phase, physicians recorded the presence or absence of 14 clinical criteria before viewing chest imaging results. We determined injury outcomes by CT radiology readings and categorized injuries as major or minor according to an expert-panel-derived clinical classification scheme. We then employed recursive partitioning to derive two DIs: Chest CT-All maximized sensitivity for all injuries, and Chest CT-Major maximized sensitivity for only major thoracic injuries (while increasing specificity). In the validation phase, we employed similar methodology to prospectively test the performance of both DIs. We enrolled 11,477 patients-6,002 patients in the derivation phase and 5,475 patients in the validation phase. The derived Chest CT-All DI consisted of (1) abnormal chest X-ray, (2) rapid deceleration mechanism, (3) distracting injury, (4) chest wall tenderness, (5) sternal tenderness, (6) thoracic spine tenderness, and (7) scapular tenderness. The Chest CT-Major DI had the same criteria without rapid deceleration mechanism. In the validation phase, Chest CT-All had a sensitivity of 99.2% (95% CI 95.4%-100%), a specificity of 20.8% (95% CI 19.2%-22.4%), and a negative predictive value (NPV) of 99.8% (95% CI 98.9%-100%) for major injury, and a sensitivity of 95.4% (95% CI 93.6%-96.9%), a specificity of 25.5% (95% CI 23.5%-27.5%), and a NPV of 93.9% (95% CI 91.5%-95.8%) for either major or minor injury. Chest CT-Major had a sensitivity of 99.2% (95% CI 95.4%-100%), a specificity of

Conventional post-mastectomy radiation therapy is delivered with tangential fields for chest wall and separate fields for regional nodes. Although chest wall and regional nodes delineation has been discussed with RTOG contouring atlas, CT-based planning to treat chest wall and regional nodes as a whole target has not been widely accepted. We herein discuss the dosimetric characteristics of a linac IMRT technique for treating chest wall and regional nodes as a whole PTV after modified radical mastectomy, and observe acute toxicities following irradiation. Patients indicated for PMRT were eligible. Chest wall and supra/infraclavicular region +/−internal mammary nodes were contoured as a whole PTV on planning CT. A simplified linac IMRT plan was designed using either integrated full beams or two segments of half beams split at caudal edge of clavicle head. DVHs were used to evaluate plans. The acute toxicities were followed up regularly. Totally, 85 patients were enrolled. Of these, 45 had left-sided lesions, and 35 received IMN irradiation. Planning designs yielded 55 integrated and 30 segmented plans, with median number of beams of 8 (6–12). The integrated and segmented plans had similar conformity (1.41±0.14 vs. 1.47±0.15, p=0.053) and homogeneity indexes (0.13±0.01 vs. 0.14±0.02, p=0.069). The percent volume of PTV receiving >110% prescription dose was <5%. As compared to segmented plans, integrated plans typically increased V 5 of ipsilateral lung (p=0.005), and heart (p=0.001) in patients with left-sided lesions. Similarly, integrated plans had higher spinal cord D max (p=0.009), ipsilateral humeral head (p<0.001), and contralateral lung D mean (p=0.019). During follow-up, 36 (42%) were identified to have ≥ grade 2 radiation dermatitis (RD). Of these, 35 developed moist desquamation. The median time to onset of moist desquamation was 6 (4–7) weeks from start of RT. The sites of moist desquamation were most frequently occurred in anterior axillary

This report describes a paediatric patient presenting with haemodynamically stable non-sustained ventricular tachycardia 1 day after minor blunt chest trauma. Initial laboratory studies, chest X-ray and echocardiography were normal; however, cardiac MRI revealed precordial haematoma, myocardial contusion and small pericardial effusion. Throughout her hospital course, she remained asymptomatic aside from frequent couplets and triplets of premature ventricular contractions. Ectopy was controlled with oral verapamil. This case highlights how significant cardiac injury may be missed with standard diagnostic algorithms. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

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.

Poland's syndrome (PS) is a congenital monolateral deformity that may involve breast, chest wall, and upper limb with different degrees of clinical expressions. In some cases, the problem is mainly cosmetic, and the reconstruction should be performed to achieve minimal scarring and donor site morbidity. The authors describe a case report of a male patient with PS who developed a severe capsular contraction after 25 years implant reconstruction, who was treated after explantation using free gracilis flap (FGF). In this patient, only the pectoralis major muscle was missing. An FGF was performed to reconstruct the anterior axillary fold and the soft tissue defect. There was no flap loss, the patient had a clearly improved appearance of the chest wall, and the pain syndrome was solved. In this case report, we demonstrate our experience with the use of an FGF for chest wall reconstruction in male patients with PS after prosthesis explantation.

Aim: To identify and to evaluate predictors that determine whether chest computed tomography (CT) is likely to reveal relevant injuries in adult blunt trauma patients. Methods: After a comprehensive literature search for original studies on blunt chest injury diagnosis, two independent observers included studies on the accuracy of parameters derived from history, physical examination, or diagnostic imaging that might predict injuries at (multidetector row) CT in adults and that allowed construction of 2 x 2 contingency tables. For each article, methodological quality was scored and relevant predictors for injuries at CT were extracted. For each predictor, sensitivity, specificity, positive and negative likelihood ratio and diagnostic odds ratio (DOR) including 95% confidence intervals were calculated. Results: Of 147 articles initially identified, the observers included 10 original studies in consensus. Abnormalities at physical examination (abnormal respiratory effort, need for assisted ventilation, reduced airentry, coma, chest wall tenderness) and pelvic fractures were significant predictors (DOR: 2.1-6.7). The presence of any injuries at conventional radiography of the chest (eight articles) was a more powerful significant predictor (DOR: 2.2-37). Abnormal chest ultrasonography (four articles) was the most accurate predictor for chest injury at CT (DOR: 491-infinite). Conclusion: The current literature indicates that in blunt trauma patients with abnormal physical examination, abnormal conventional radiography, or abnormal ultrasonography of the chest, CT was likely to reveal relevant chest injuries. However, there was no strong evidence to suggest that CT could be omitted in patients without these criteria, or whether these findings are beneficial for patients

Plastic surgery in chest wall reconstruction: relevant aspects - case series

Directory of Open Access Journals (Sweden)

Diogo Franco

Full Text Available Objective: to discuss the participation of Plastic Surgery in the reconstruction of the chest wall, highlighting relevant aspects of interdisciplinaryness. Methods: we analyzed charts from 20 patients who underwent extensive resection of the thoracic integument, between 2000 and 2014, recording the indication of resection, the extent and depth of the raw areas, types of reconstructions performed and complications. Results: among the 20 patients, averaging 55 years old, five were males and 15 females. They resections were: one squamous cell carcinoma, two basal cell carcinomas, five chondrosarcomas and 12 breast tumors. The extent of the bloody areas ranged from 4x9 cm to 25x40 cm. In 12 patients the resection included the muscular plane. In the remaining eight, the tumor removal achieved a total wall thickness. For reconstruction we used: one muscular flap associated with skin grafting, nine flaps and ten regional fasciocutaneous flaps. Two patients undergoing reconstruction with fasciocutaneous flaps had partially suffering of the flap, solved with employment of a myocutaneous flap. The other patients displayed no complications with the techniques used, requiring only one surgery. Conclusion: the proper assessment of local tissues and flaps available for reconstruction, in addition to the successful integration of Plastic Surgery with the specialties involved in the treatment, enable extensive resections of the chest wall and reconstructions that provide patient recovery.

Full Text Available A 71-year-old man was referred for an anterior chest wall mass. Chest computed tomography (CT and positron emission tomography-CT suggested a malignant tumor. Surgical biopsy through a vertical subxiphoid incision revealed an extra-gastrointestinal stromal tumor (EGIST. En bloc resection of the tumor, including partial resection of the sternum, costal cartilage, pericardium, diaphragm, and peritoneum, was performed. Pathologic evaluation revealed a negative resection margin and confirmed the tumor as an EGIST. On postoperative day 17, the patient was discharged without any complications. At the 2-week follow-up, the patient was doing well and was asymptomatic.

A 9-year-old boy was referred to the Oncology Department because of a thoracic soft-tissue mass thought to be a chest wall tumour. He had a history of grass inflorescence (Hordeum murinum) aspiration 2 weeks prior to this admission. On physical examination a tender soft-tissue mass under the right scapula and diminished breath sounds from the right lower lobe were detected. Thoracic CT confirmed soft-tissue swelling of the right posterior chest wall. There was a hypodense area within the soft-tissue mass suggesting a foreign body and also focal consolidation of the right lower lobe adjacent to the soft-tissue swelling. We report here unique CT findings of grass inflorescence aspiration before and after its migration through the airways. (orig.)

The percentage of adipose (fat) tissue in the chest wall must be known to accurately measure Pu in the human lung. Correction factors of 100% or more in x-ray detection efficiency are common. Methods using simple 40 K and biometric measurement techniques were investigated to determine the adipose content in the human chest wall. These methods predict adipose content to within 15% of the absolute ultrasonic value. These new methods are discussed and compared with conventional ultrasonic measurement techniques

A simple technique using a contralateral deltopectoral flap is described for the immediate repair of defects of the chest wall resulting from excision of radionecrosis or persistent tumour after radiotherapy. Successful use in 3 consecutive cases has shown that the deltopectoral flap may be rotated through a full 180/sup 0/ without compromise of blood supply and that primary healing may be obtained.

Don't Forget the Abdominal Wall: Imaging Spectrum of Abdominal Wall Injuries after Nonpenetrating Trauma.

Abdominal wall injuries occur in nearly one of 10 patients coming to the emergency department after nonpenetrating trauma. Injuries range from minor, such as abdominal wall contusion, to severe, such as abdominal wall rupture with evisceration of abdominal contents. Examples of specific injuries that can be detected at cross-sectional imaging include abdominal muscle strain, tear, or hematoma, including rectus sheath hematoma (RSH); traumatic abdominal wall hernia (TAWH); and Morel-Lavallée lesion (MLL) (closed degloving injury). These injuries are often overlooked clinically because of (a) a lack of findings at physical examination or (b) distraction by more-severe associated injuries. However, these injuries are important to detect because they are highly associated with potentially grave visceral and vascular injuries, such as aortic injury, and because their detection can lead to the diagnosis of these more clinically important grave traumatic injuries. Failure to make a timely diagnosis can result in delayed complications, such as bowel hernia with potential for obstruction or strangulation, or misdiagnosis of an abdominal wall neoplasm. Groin injuries, such as athletic pubalgia, and inferior costochondral injuries should also be considered in patients with abdominal pain after nonpenetrating trauma, because these conditions may manifest with referred abdominal pain and are often included within the field of view at cross-sectional abdominal imaging. Radiologists must recognize and report acute abdominal wall injuries and their associated intra-abdominal pathologic conditions to allow appropriate and timely treatment. © RSNA, 2017.

Sarcomas are a rare complication of radiotherapy for breast cancer and such patients have a poor prognosis. We report resection of an osteosarcoma in the chest wall that developed 20 years after postoperative radiotherapy for breast cancer. A 57-year-old woman was referred to our department for examination and treatment of an anterior chest wall tumor in April 2007. In September 1986, she had undergone a radical mastectomy and postoperative irradiation and chemotherapy for right breast cancer. In December 2003, she underwent chemotherapy for recurrence of breast cancer which was pointed out on computed tomography involving the pleura and left superior clavicular lymph nodes. In March 2006, follow-up computed tomography of the chest demonstrated the destruction of the sternum, which was diagnosed as recurrence and she was followed with chemotherapy for breast cancer continuously thereafter. In April 2007, because of the developing sternal tumor, excisional biopsy was performed and histopathology indicated sarcoma. In May 2007, resection of the chest wall tumor with the sternum, bilateral clavicles, bilateral first and second ribs, and right partial lung (upper and middle lobe) were performed, and the chest wall defect was reconstructed with a rectus abdominis musculocutaneous free flap. Histopathologically, the tumor was osteosarcoma with margin free. Adjuvant radiotherapy to the breast plays a significant role in preventing local disease recurrence in women treated for breast cancer. However, radiotherapy can induce malignant sarcoma after a latency period of several years. The risk is extremely low for the individual patient, but this disease is aggressive and associated with a poor overall prognosis. Therefore, early detection is necessary for optimal treatment and incisional biopsy is necessary for accurate diagnosis. (author)

A 73-year-old woman who had been followed in our department of gynecology because of ovarian cancer since 2002, was admitted with liver dysfunction and complaining of back pain and light precordial chest pain. The chest radiograph on admission revealed a tumor in her left upper lung field, and chest CT revealed a tumor adjacent to the chest wall and mediastinum. FDG-positron emission tomography (PET) showed abnormal uptake in the tumor and Th6/7, and the subaortic lymph nodes. On the basis of these findings, primary lung cancer with bone metastasis was suspected. She had a high grade fever on admission, and blood cultures were positive for group G streptococcus. The treatment with intravenous penicillin was started. Percutaneous biopsy of the tumor in her left chest showed an abscess wall in the chest wall, but no evidence of malignancy. Transbronchial lung biopsy and CT-guided biopsy also showed no malignant cells. Since the tumor decreased in size and back pain improved gradually by only antibiotic treatment, a diagnosis of sepsis of group G streptococcus, chest wall abscess, and vertebral osteomyelitis was made. She was treated with intravenous penicillin for 4 weeks and oral amoxicillin for another 4 weeks. After 60 days of antibiotic treatment, the tumor vanished.

The percentage of adipose (fat) tissue in the chest wall must be known to accurately measure Pu in the human lung. Correction factors of 100% or more in X-ray detection efficiency are common in a normal population of individuals of differing body composition and have been determined in the past by means of elaborate and costly ultrasonic measurements of the subject's chest. Methods using simple 40 K and biometric measurement techniques have been investigated to determine the adipose content in the human chest wall. These methods compare favorably with ultrasonic measurements and allow laboratories not possessing ultrasonic equipment to make appropriate corrections for x-ray detection efficiency. These methods predict adipose content to within 15% of the absolute ultrasonic value. (author)

Chest wall thickness measurements and the dosimetric implications for male workers in the uranium industry

Kramer, Gary H.; Hauck, Barry M.; Allen, Steve A.

2000-01-01

The Human Monitoring Laboratory has measured the chest wall thickness and adipose mass fraction of a group of workers at three Canadian uranium refinery, conversion plant, and fuel fabrication sites using ultrasound. A site specific biometric equation has been developed for these workers, who seem to be somewhat larger than other workers reported in the literature. The average chest wall thickness of the seated persons measured at the uranium conversion plant and refinery was about 3.8 cm, and at the fuel fabrication facility was 3.4 cm. These values are not statistically different. Persons measured in a seated geometry had a thinner chest wall thickness than persons measured in a supine geometry - the decrease was in the range of 0.3 cm to 0.5 cm. It follows that a seated geometry will give a lower MDA (or decision level) than a supine geometry. Chest wall thickness is a very important modifier for lung counting efficiency and this data has been put into the perspective of the impending Canadian dose limits that will reduce the limit of occupationally exposed workers to essentially 20 mSv per year. Natural uranium must be measured based on the 235 U emissions at these type of facilities. The refining and conversion process removes 234 Th and the equilibrium is disturbed. This is unfortunate as the MDA values for this nuclide are approximately a factor of three lower than the values quoted below. The sensitivity of the germanium and phoswich based lung counting system has been compared. Achievable MDA's (30 minute counting time) with a four-phoswich-detector array lie in the range of 4.7 mg to 13.5 mg of natural uranium based on the 235 U emissions over a range of chest wall thicknesses of 1.6 cm to 6.0 cm. The average achievable MDA is about 8.5 mg which can be reduced to about 6.2 mg by doubling the counting time. Similarly, MDA's (30 minute counting time) obtainable with a germanium lung counting system will lie in the range of 3 mg to 28 mg of natural uranium

Chest trauma is a frequent problem arising from lesions caused by domestic and occupational activities and especially road traffic accidents. These injuries can be analyzed from distinct points of view, ranging from consideration of the most severe injuries, especially in the context of multiple trauma, to the specific characteristics of blunt and open trauma. In the present article, these injuries are discussed according to the involvement of the various thoracic structures. Rib fractures are the most frequent chest injuries and their diagnosis and treatment is straightforward, although these injuries can be severe if more than three ribs are affected and when there is major associated morbidity. Lung contusion is the most common visceral lesion. These injuries are usually found in severe chest trauma and are often associated with other thoracic and intrathoracic lesions. Treatment is based on general support measures. Pleural complications, such as hemothorax and pneumothorax, are also frequent. Their diagnosis is also straightforward and treatment is based on pleural drainage. This article also analyzes other complex situations, notably airway trauma, which is usually very severe in blunt chest trauma and less severe and even suitable for conservative treatment in iatrogenic injury due to tracheal intubation. Rupture of the diaphragm usually causes a diaphragmatic hernia. Treatment is always surgical. Myocardial contusions should be suspected in anterior chest trauma and in sternal fractures. Treatment is conservative. Other chest injuries, such as those of the great thoracic and esophageal vessels, are less frequent but are especially severe.

A 62 years-old woman had visited our hospital with the large and deep ulcer formation on the left anterior chest wall. A biopsy of the ulcerous lesion established the diagnosis of a squamous cell carcinoma which might be induced by the irradiation after mastectomy. Although a wide resection of the chest wall including left arm was performed, it was impossible to resect completely. After then, she had operations for local recurrence three times in three years. However, cure was not obtained, and residual lesions gradually enlarged and all layers of the anterior chest wall were replaced with tumor tissues. Conventional chemotherapy using futraful and mytomycin C was not effective. Therefore, we tried combined therapy with intravenous administration of cisplatin (CDDP) and vindesine (VDS), and local hyperthermia using radiofrequency (RF) wave. A total number of 11 courses of this treatment modality was carried out at once a week intervals. The tumor-temperature was maintained at the range of 40-43degC for 40 min in each treatment session. Chemotherapeutic agents were administered simultaneously with hyperthermia. After these treatment, the recurrent tumor was markedly reduced, and epithelization of the ulcer was recognized from the surrounding normal skin. The residual tumor was then resected completely. The operative wound was successfully closed by surrounding normal tissue mobilization. She is in good postoperative condition. We concluded that the chemo-thermotherapy is safe and promising therapeutic modality for such invasive squamous cell carcinoma, and the normal tissues are not affected. Furthermore, this approach will expand the scope of radical resection for such an uncontrollable tumor. (author).

To describe clinical outcomes of etonogestrel implant patients with migration to the vasculature, chest wall and other distant body sites spontaneously reported to the US Food and Drug Administration Adverse Event Reporting System (FAERS) database. We performed a standardized Medical Dictionary for Regulatory Activities (MedDRA) query in the FAERS database (through November 15, 2015), with reports coded with one or more MedDRA preferred terms that indicate complications with device placement or migration of the device from the original site of insertion to the vasculature, chest wall and other distant body sites. We excluded any cases previously described in the medical literature. We identified 38 cases of pronounced etonogestrel implant migration. Migration locations included the lung/pulmonary artery (n=9), chest wall (n=1), vasculature at locations other than the lung/pulmonary artery (n=14) and extravascular migrations (n=14) to other body sites (e.g., the axilla and clavicle/neck line/shoulder). The majority of cases were asymptomatic and detected when the patient desired implant removal; however, seven cases reported symptoms such as pain, discomfort and dyspnea in association with implant migration. Three cases also describe pulmonary fibrosis and skin reactions as a result of implant migration to the vasculature, chest wall and other distant body sites. Sixteen cases reported surgical removal in an operating room setting. Our FAERS case series demonstrates etonogestrel implant migration to the vasculature, chest wall and other body sites distant from the site of original insertion. As noted by the sponsor in current prescribing information, a key determinant in the risk for etonogestrel contraceptive implant migration appears to be improper insertion technique. Although migration of etonogestrel implants to the vasculature is rare, awareness of migration and education on proper insertion technique may reduce the risk. Published by Elsevier Inc.

Rib fractures in children under the age of 2 years have a strong correlation with non-accidental injury (NAI). Follow-up radiographs can improve detection. To evaluate the value of the follow-up chest radiograph in suspected non-accidental injury. The study included all children less than 2 years of age who were investigated for suspected NAI in our institution between January 1998 and October 2003. Prior to January 2000, only selected patients were asked to attend for a follow-up chest radiograph. From January 2000 onwards all children were asked to reattend. Of 200 children included in the study, 59 (29.5%) reattended for a follow-up chest radiograph. The follow-up film provided useful additional information in 7 (12%) of the 59 children. In two children rib fractures were noted only on the follow-up chest radiograph. In a further two patients additional rib fractures were noted. Additional dating information was obtained for two patients. For one child both additional fractures and dating information were noted. The follow-up chest radiograph provides useful information in children with suspected NAI and it is recommended that it should be included routinely in the imaging investigations of these children.

Rib fractures in children under the age of 2 years have a strong correlation with non-accidental injury (NAI). Follow-up radiographs can improve detection. To evaluate the value of the follow-up chest radiograph in suspected non-accidental injury. The study included all children less than 2 years of age who were investigated for suspected NAI in our institution between January 1998 and October 2003. Prior to January 2000, only selected patients were asked to attend for a follow-up chest radiograph. From January 2000 onwards all children were asked to reattend. Of 200 children included in the study, 59 (29.5%) reattended for a follow-up chest radiograph. The follow-up film provided useful additional information in 7 (12%) of the 59 children. In two children rib fractures were noted only on the follow-up chest radiograph. In a further two patients additional rib fractures were noted. Additional dating information was obtained for two patients. For one child both additional fractures and dating information were noted. The follow-up chest radiograph provides useful information in children with suspected NAI and it is recommended that it should be included routinely in the imaging investigations of these children.

Purpose: Indications for postmastectomy radiation include primary tumor size > 5 cm and ≥ 4 positive axillary nodes. In clinical practice, patients with a close or positive margin after mastectomy are also often treated with postmastectomy radiation. However, there is little data regarding the risk of a chest wall recurrence in patients with this pathologic feature who otherwise would be considered low risk (tumor size 25% at 8 years: Age ≤ 50 years was 28% vs. 0% for age > 50 (p=0.08). There was no correlation with chest wall failure and number of nodes, ER status, lymphovascular invasion, location of primary, grade, family history or type of tumor close to the margin. All four chest wall failures were in patients who had received adjuvant systemic chemotherapy ± Tamoxifen. Chest wall failures occurred in patients with margins within 1-2 mm in three patients and 5 mm in one patient. The cumulative chest wall recurrence at 8 years by margin proximity was 24% ≤ 2mm vs. 7% 2.1-6 mm (p=0.44), and by clinical size 24% for T2 tumors vs. 7% for T1 (p=0.55). Conclusions: A close or positive margin is uncommon (< 5%) after mastectomy in patients with tumor size < 5 cm and 0-3 positive axillary nodes, but when present it appears to be in a younger patient population. The subgroup of patients aged 50 or younger with clinical T1-T2 tumor size and 0-3 positive nodes who have a close (≤ 5 mm) or positive mastectomy margin are at high risk (28% at 8 years) for chest wall recurrence regardless of adjuvant systemic therapy, and therefore we recommend they be considered for postmastectomy radiation. This high risk of local failure was not observed in patients over age 50, suggesting this subgroup may not require adjuvant chest wall irradiation

Sarcoidosis is an inflammatory disorder that is characterized by the presence of noncaseating granulomas in tissues, involving many organs and tissues. Extra-pulmonary, especially muscular sarcoidosis is a rare condition. The most common location of the muscular sarcoidosis is known to be the proximal muscles of the extremities; however, there have been no cases of diffuse involvement of the chest and abdominal wall muscles. Here, we report a rare muscular sarcoidosis with infiltrative pattern in the chest and abdominal wall muscles and describe the MR imaging findings that were mistaken as lymphoma at initial diagnosis. Although our case did not show characteristic MR findings of muscular sarcoidosis, clinicians or radiologists who are aware of these imaging features can perform early systemic survey for sarcoidosis. Also muscle biopsy is very important to confirm the sarcoidosis and distinguish it from other tumors. (orig.)

Gastrointestinal hollow viscus injury after blunt chest and abdominal trauma is uncommon and complicates 0.6%-1.2% of all cases of trauma. Early recognition of such injuries significantly decreases morbidity and mortality. Since physical examination is not accurate in detecting such injuries, contrast-enhanced computed tomography has been the mainstay for diagnosis in many emergency departments. This pictorial essay aims to review the incidence, mechanisms, and signs of gastrointestinal hollow viscus injuries in the setting of blunt chest and abdominal trauma.

To describe the management of thoracic reconstructions in the presence of primary chest-wall infection (PCWI) or secondary deep chest-wall infection (SCWI), focussing on local tolerance of a titanium rib osteosynthesis system. PCWI included infected chest wall tumours (CWT), infected T3 non-small-cell lung carcinoma (NSCLC) and open flail chest. SCWI was defined by deep infection of previous thoracic-wall reconstructions. Infection was identified by preoperative bacterial analysis of the tumour or surgical site. In PCWI, a one-step procedure combined extensive resection of infected tissues and rigid reconstruction of the defect; skeletal rigidity was achieved using titanium implants. In SCWI, we removed all synthetic material except titanium implants. In both groups, the surgical field was thoroughly cleaned and implants were wrapped or covered by flaps. From January 2005 to December 2011, 11 patients (54 ± 10.2 years) with either PCWI (3 CWT, 3 T3 NSCLC, 1 open flail chest) or SCWI (3 CWT, 1 funnel chest) were treated. Infection was polymicrobial in all but 1 case. Bacteria observed in PCWI patients were multidrug resistant. In PCWI, we resected 4.2 ± 0.6 ribs en bloc with the lung (n = 5), the skin and the pectoralis major and then used mesh and 2.1 ± 1.2 titanium implants for reconstruction (n = 6). The mean defect was 1154.4 ± 318 cm(3). Surgical SCWI management removed polytetrafluoroethylene-mesh and preserved the titanium implants. A Vicryl mesh (n = 3) and greater omentum flap (n = 3) were added. One of the 2 postoperative deaths in the PCWI group was related to infection recurrence. No other patient had infection at the 6-month follow-up with leucocyte-labelled scintigraphy. Titanium rib osteosynthesis is reliable in two complex and life-threatening situations: PCWIs and SCWIs. In combination with a flap, this allows rapid, reliable, rigid reconstruction of infected full-thickness chest-wall defects in a single-step procedure.

Postoperative pulmonary complications are common. Between patients there are differences in lung and chest wall mechanics. Individualised mechanical ventilation based on measurement of transpulmonary pressures would be a step forward. A previously described method evaluates lung and chest wall mechanics from a change of ΔPEEP and calculation of change in end-expiratory lung volume (ΔEELV). The aim of the present study was to validate this PEEP-step method (PSM) during general anaesthesia by comparing it with the conventional method using oesophageal pressure (PES) measurements. In 24 lung healthy subjects (BMI 18.5-32), three different sizes of PEEP steps were performed during general anaesthesia and ΔEELVs were calculated. Transpulmonary driving pressure (ΔPL) for a tidal volume equal to each ΔEELV was measured using PES measurements and compared to ΔPEEP with limits of agreement and intraclass correlation coefficients (ICC). ΔPL calculated with both methods was compared with a Bland-Altman plot. Mean differences between ΔPEEP and ΔPL were mechanical properties among the lung healthy patients stresses the need for individualised ventilator settings based on measurements of lung and chest wall mechanics. The agreement between ΔPLs measured by the two methods during general anaesthesia suggests the use of the non-invasive PSM in this patient population. NCT 02830516. Copyright © 2017 The Authors.

Mechanisms and Clinical Management of Ventricular Arrhythmias following Blunt Chest Trauma

Directory of Open Access Journals (Sweden)

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 early and accurate identification of patients with blunt thoracic aortic injury (BTAI) remains a challenge. Traditionally, a portable AP chest X-ray (CXR) is utilized as the initial screening modality for BTAI, however, there is controversy surrounding its sensitivity. The purpose of this study was to assess the sensitivity of CXR as a screening modality for BTAI. After IRB approval, all adult (≥18 yo) blunt trauma patients admitted to LAC+USC (01/2011-12/2013) who underwent CXR and chest CT were retrospectively reviewed. Final radiology attending CXR readings were reviewed for mediastinal abnormalities (widened mediastinum, mediastinal to chest width ratio greater than 0.25, irregular aortic arch, blurred aortic contour, opacification of the aortopulmonary window, and apical pleural haematoma) suggestive of aortic injury. Chest CT final attending radiologist readings were utilized as the gold standard for diagnosis of BTAI. The primary outcome analyzed was CXR sensitivity. A total of 3728 patients were included in the study. The majority of patients were male (72.6%); mean age was 43 (SD 20). Median ISS was 9 (IQR 4-17) and median GCS was 15 (IQR 14-15). The most common mechanism of injury was MVC (48.0%), followed by fall (20.6%), and AVP (16.9%). The total number of CXRs demonstrating a mediastinal abnormality was 200 (5.4%). Widened mediastinum was present on 191 (5.1%) of CXRs, blurred aortic contour on 10 (0.3%), and irregular aortic arch on 4 (0.1%). An acute aortic injury confirmed by chest CT was present in 17 (0.5%) patients. Only 7 of these with CT-confirmed BTAI had a mediastinal abnormality identified on CXR, for a sensitivity of 41% (95% CI: 19-67%). The results from this study suggest that CXR alone is not a reliable screening modality for BTAI. A combination of screening CXR and careful consideration of other factors, such as mechanism of injury, will be required to effectively discriminate between those who should and should not undergo chest

A case of radiation-induced sarcoma of the chest wall after radiation therapy for breast cancer is reported. A 69-year-old woman underwent mastectomy with axillary lymph node dissection followed by linac therapy of 50 Gy delivered to the left axilla, left supraclavicular area, and parasternal area. During therapy for bone and liver metastases, a tumor was noted in the left chest wall 15 years after radiation therapy. Incisional biopsy was performed. Histological diagnosis was spindle cell sarcoma. Radiation-induced sarcoma was suspected because the tumor developed 15 years after radiation therapy within the same area. Radiation-induced sarcoma is a rare tumor, but radiation therapy following breast-conserving therapy is widely employed. It is important to be aware of the possibility of radiation-induced sarcoma.

We report a case of concomitant injury to the aortic valve and internal mammary artery (IMA) from nonpenetrating chest trauma. To our knowledge, this is the first such case to be reported. Transcatheter arterial embolization (TAE) following diagnostic angiography offers an effective and minimally invasive treatment for traumatic IMA injuries. Because there might be an asymptomatic interval after traumatic aortic valve injuries, serial physical examinations and repeated echocardiography should be mandatory for patients with de novo heart failure after blunt chest trauma. Transesophageal echocardiography can provide a clearer image of cardiac injuries than transthoracic echocardiography, particularly if there is extensive anterior mediastinal hematoma resulting from IMA trauma.

To assess the usefulness of cine-magnetic resonance imaging (cine-MRI) in the evaluation of chest wall invasion, we compared the results of cine-MRI with those of computed tomography (CT) and ultrasonography (US). Eleven patients were examined who had no pain and who were difficult to diagnose by routine examinations. MRI was performed with a Magnetom SP/4000, 1.5T unit (Siemens, Germany). For cine imaging, continuous turbo-FLUSH (ultra fast low angle shot) images were obtained at an orthogonal section to the chest wall during slow deep breathing. A CT scan was performed using a TCT 900S or Super Helix (Toshiba, Japan) at 1 cm intervals, with section thicknesses of 1 cm throughout the entire chest. US was performed with a model SSA-270A (Toshiba, Japan) with 7.5-MHz linear array scanners (PLF-705S; Toshiba, Japan). Sensitivity, specificity and accuracy were 67%, 75% and 73% for cine MRI, 67%, 63% and 64% for CT, 33%, 75% and 64% for US, respectively. These results indicate that cine MRI is potentially useful for the diagnosis of chest wall invasion of lung cancer. (author)

Full text: Second cancer induction in the contralateral breast (CB) is an issue of some concern in breast radiotherapy especially for women under the age of 45 years at the time of treatment. The CB dose from 2-field and 3-field techniques in post-mastectomy chest wall irradiations in an anthropomorphic phantom as well as in patients were measured using thermoluminescent dosimeters (TLDs) at the local radiotherapy center. Breast and chest wall radiotherapy treatments were planned conformally (3D-CRT) and delivered using 6-MV photons. The measured CB dose at the surface fell sharply with distance from the field edge. However, the average ratio of the measured to the calculated CB dose using the pencil beam algorithm at the surface was approximately 53%. The mean and median measured internal dose at the posterior border of CB in a phantom was 5.47 ± 0.22 c G y and 5.44 c G y, respectively. The internal CB dose was relatively independent of depth. In the present study the internal CB dose is 2.1-4.1 % of the prescribed dose which is comparable to the values reported by other authors.

We present a case of traumatic intercostal pulmonary herniation in an 11-year-old boy after blunt trauma to the chest, without associated chest wall disruption or pneumothorax. This condition is especially uncommon in children, with only 5 previously reported cases and most occurring after penetrating chest trauma. To date, there are no reports in literature describing traumatic intercostal lung herniation at the diaphragmatic junction with a closed chest cavity in a child. The number of traumatic lung herniation diagnoses may be expanded by a more liberal use of computed tomography when serious injury is suspected. Computed tomography and advanced imaging should be considered in pediatric trauma patients presenting with concern for intrathoracic injury that may not be seen on plain film. Traumatic blunt intrathoracic and intra-abdominal injuries in the pediatric population that are within proximity of diaphragmatic insertion should be thoroughly evaluated to rule out diaphragmatic injury. As in our case, invasive surgical intervention such as thoracoscopy may be necessary.

The multiple neurofibromatosis is an autosomal dominant hereditary disease associated to malignant schwannoma in about 3% of the cases and very rarely to others cancers. The study provides information on the case of a 32 year-old woman who suffers from this disease and presented two synchronous cancers: a papillary carcinoma of thyroid and a malignant schwannoma of the chest wall. The thyroid tumour was managed with hemithyroidectomy, hormonotherapy and radiotherapy, and the lesion of the thoracic wall was treated with local radical resection application of Marlex mesh and rotation of a musculocutaneous flap of the dorsal muscle. A review of the literature on the clinical aspects of this association and the surgical techniques employed to cover the defect of the chest wall is presented. (authors)

Functional exercise capacity, lung function and chest wall deformity in patients with adolescent idiopathic scoliosis

Directory of Open Access Journals (Sweden)

Evandro Fornias Sperandio

Full Text Available AbstractIntroduction The adolescent idiopathic scoliosis (AIS causes changes on the compliance of the chest. These changes may be associated with impaired lung function and reduced functional exercise capacity of these adolescents. We aimed to evaluate the correlation between functional exercise capacity, lung function and geometry of the chest at different stages of AIS.Materials and methods The study was carried out in a cross-sectional design which were evaluated 27 AIS patients at different stages of the disease. For chest wall evaluation, were created geometry angles/distances (A/D, which were quantified by Software Postural Assessment. The functional exercise capacity was assessed by a portable gas analyzer during the incremental shuttle walk test (ISWT. Besides that, manovacuometry and spirometry were also performed.Results Linear regressions showed that oxygen uptake (peak VO2 was correlated with distance travelled in the ISWT (R2 = 0.52, maximal respiratory pressures, cough peak flow (R2 = 0.59 and some thoracic deformity markers (D1, D2 and A6.Discussion We observed that the chest wall alterations, lung function and respiratory muscle strength are related to the functional exercise capacity and may impair the physical activity performance in AIS patients.Final considerations There is correlation between functional exercise capacity, lung function and geometry of the chest in AIS patients. Our results point to the possible impact of the AIS in the physical activities of these adolescents. Therefore, efforts to prevent the disease progression are extremely important.

Analysis of the impact of chest wall constraints on eligibility for a randomized trial of stereotactic body radiotherapy of peripheral stage 1 non-small cell lung cancer

Chest wall toxicities are recognized complications of stereotactic radiotherapy (SBRT) in non-small cell lung cancer. To minimize toxicity, the Trans-Tasman Radiation Oncology Group (TROG) 09.02 ‘CHISEL’ study protocol excluded patients with tumours within 1cm of the chest wall. The purpose of this study is to evaluate the implication of chest wall proximity constraints on patient eligibility, toxicity and potential accrual. Exclusion zones of 1cm beyond the mediastinum and 2cm beyond the bifurcation of the lobar bronchi were incorporated into the CHISEL credentialing CT dataset. Volumes of lung within which tumours varying from 1cm to 5cm in diameter may occupy and remain eligible for the CHISEL study were calculated. These volumes were compared to a hypothetical model in which the 1cm chest wall proximity restriction was removed. The percentage of lung area in which a tumour mass can occupy and be suitable for CHISEL in the left and right lung were 54% and 60% respectively. Removing the constraint increased the percentage of available lung to 83% and 87% respectively. Considering a 2cm spherical tumour, only 21% and 31% of tumours in the left and right lung would be eligible with the chest wall constraint, whilst 39% and 50% respectively would be eligible without the constraint. The exclusion of tumours less than 1cm to chest wall significantly reduces the proportion of patients eligible for the CHISEL protocol. A review of the literature pertaining to chest wall toxicity after stereotactic radiotherapy supports a change in chest wall exclusion criteria for the CHISEL study.

Matching Electron Beams Without Secondary Collimation for Treatment of Extensive Recurrent Chest-Wall Carcinoma

Feygelman, Vladimir; Mandelzweig, Yuri; Baral, Ed

2015-01-01

Matching electron beams without secondary collimators (applicators) were used for treatment of extensive, recurrent chest-wall carcinoma. Due to the wide penumbra of such beams, the homogeneity of the dose distribution at and around the junction point is clinically acceptable and relatively insensitive to positional errors. Specifically, dose around the junction point is homogeneous to within ±4% as calculated from beam profiles, while the positional error of 1 cm leaves this number essentially unchanged. The experimental isodose distribution in an anthropomorphic phantom supports this conclusion. Two electron beams with wide penumbra were used to cover the desired treatment area with satisfactory dose homogeneity. The technique is relatively simple yet clinically useful and can be considered a viable alternative for treatment of extensive chest-wall disease. The steps are suggested to make this technique more universal.

Purpose: For left-sided PU patients requiring CW and nodal irradiation, sometimes partial wide tangents (PWT) are not feasible due to abnormal chest wall contour or heart position close to the anterior chest wall or unusual wide excision scar. We developed an energy modulated electron chest wall irradiation technique that will achieve heart sparing. Methods: Ten left-sided PU patients were selected for this dosimetry study. If PWT were used, the amount of the ipsilateral lung would be ranged 3.4 to 4.4 cm, and the amount of heart would be ranged 1.3 to 3.8 cm. We used electron paired fields that matched on the skin to achieve dose conformity to the chest wall. The enface electron fields were designed at extended SSD from a single isocenter and gantry angle with different energy beams using different cutout. Lower energy was used in the central chest wall part and higher energy was used in the periphery of the chest wall. Bolus was used for the electron fields to ensure adequate skin dose coverage. The electron fields were matched to the photon supra-clavicle field in the superior region. Daily field junctions were used to feather the match lines between all the fields. Target volumes and normal tissues were drawn according to institutional protocols. Prescription dose was 2Gy per fraction for a total 50Gy. Dose calculations were done with Eclipse EMC-11031 for Electron and AAA-11031 for photons. Results: Six patients were planned using 6/9MeV, three using 9/12MeV and one 6/12MeV. Target volumes achieved adequate coverage. For heart, V30Gy, V20Gy and Mean Dose were 0.6%±0.6%, 2.7%±1.7%, and 3.0Gy±0.8Gy respectively. For ipsilateral lung, V50Gy, V20Gy, V10Gy and V5Gy were 0.9%±1.1%, 34.3%±5.1%, 51.6%±6.3% and 64.1%±7.5% respectively. Conclusion: For left-sided PU patients with unusual anatomy, energy modulated electron CW irradiation technique can achieve heart sparing with acceptable lung dose.

Retained foreign bodies in the chest may include shell fragments, bullets, shrapnel, pieces of clothing, bones, and rib fragments. The risks of removal of foreign bodies must be weighed against the complications of leaving them inside the chest. We treated 90 cases of retained intrathoracic foreign bodies in patients admitted to 3 tertiary centers in Saudi Arabia between March 2015 and March 2016. Sixty patients were injured by shrapnel, 26 had one or more bullets, 3 had broken rib fragments, and one had a metal screw. The chest wall was site of impaction in 48 cases, the lungs in 24, pleura in 14, and mediastinum in 4. Removal of the retained foreign body was carried out in 12 patients only: bullets in 9 cases, bone fragments in 2, and a metal screw in one. The predictors for removal were bullets, female sex, and mediastinal position with bilateral chest injury, especially with fracture ribs. Retained intrathoracic foreign bodies due to penetrating chest trauma are treated mainly conservatively unless there is another indication for chest exploration. © The Author(s) 2016.

Fully automated chest wall line segmentation in breast MRI by using context information

Breast MRI has emerged as an effective modality for the clinical management of breast cancer. Evidence suggests that computer-aided applications can further improve the diagnostic accuracy of breast MRI. A critical and challenging first step for automated breast MRI analysis, is to separate the breast as an organ from the chest wall. Manual segmentation or user-assisted interactive tools are inefficient, tedious, and error-prone, which is prohibitively impractical for processing large amounts of data from clinical trials. To address this challenge, we developed a fully automated and robust computerized segmentation method that intensively utilizes context information of breast MR imaging and the breast tissue's morphological characteristics to accurately delineate the breast and chest wall boundary. A critical component is the joint application of anisotropic diffusion and bilateral image filtering to enhance the edge that corresponds to the chest wall line (CWL) and to reduce the effect of adjacent non-CWL tissues. A CWL voting algorithm is proposed based on CWL candidates yielded from multiple sequential MRI slices, in which a CWL representative is generated and used through a dynamic time warping (DTW) algorithm to filter out inferior candidates, leaving the optimal one. Our method is validated by a representative dataset of 20 3D unilateral breast MRI scans that span the full range of the American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) fibroglandular density categorization. A promising performance (average overlay percentage of 89.33%) is observed when the automated segmentation is compared to manually segmented ground truth obtained by an experienced breast imaging radiologist. The automated method runs time-efficiently at ~3 minutes for each breast MR image set (28 slices).

Hydatid disease is rarely encountered among the population of the United States, but it affects several million people in sheep-raising regions of the world. Human infestation with Echinococcus granulosus begins following ingestion of its ova, which are excreted into the contaminated water during the usual dog-sheep cycle. Hydatid cysts will then develop most frequently in the liver (75% of cases) and lungs (15%) of the human host. Skeletal involvement has been reported to occur in only 0.5-4.0% of patients in the endemic areas. Because of the rarity and perplexing imaging features of hydatid disease involving the chest wall, we wish herein to present a case evaluated recently at our institution. 5 refs., 1 fig.

This is a pictorial essay in which we review and illustrate a variety of thoracic injuries related to blunt trauma. Non-aortic blunt thoracic trauma can be divided anatomically into injuries of the chest wall, lungs, pleura, mediastinum, and diaphragm. Some injuries involve more than one anatomic compartment, and multiple injuries commonly coexist. This article provides common imaging findings and discussion of both common and uncommon but critical thoracic injuries encountered. Published by Elsevier Inc.

Introduction: Indications for postmastectomy radiation include primary tumor size ≥5 cm and/or ≥4 positive axillary nodes. In clinical practice, patients with a close or positive margin after mastectomy are also often treated with postmastectomy radiation. However, there is little data regarding the risk of a chest wall recurrence in patients with close or positive margins who otherwise would be considered low risk (tumor size 50 (p = 0.04). There was no correlation with chest wall failure and number of positive nodes, ER status, lymphovascular invasion, location of primary, grade, family history, or type of tumor close to the margin. Of 5 chest wall failures, 4 were in patients who had received adjuvant systemic chemotherapy ± tamoxifen. Chest wall failures occurred in 1 patient with a positive deep margin, 3 patients with margins within 2 mm, and 1 patient with a margin of 5 mm. The estimated cumulative incidence probability of chest wall recurrence at 8 years by margin proximity was 24% ≤ 2 mm vs. 7% 2.1-6 mm (p = 0.36), and by clinical size 24% for T2 tumors vs. 7% for T1 (p = 0.98). Conclusions: A close or positive margin is uncommon (≤5%) after mastectomy in patients with tumor size <5 cm and 0-3 positive axillary nodes but, when present, it appears to be in a younger patient population. The subgroup of patients aged 50 or younger with clinical T1-T2 tumor size and 0-3 positive nodes who have a close (≤5 mm) or positive mastectomy margin are at high risk (28% at 8 years) for chest wall recurrence regardless of adjuvant systemic therapy and, therefore, should be considered for postmastectomy radiation

Full Text Available In this study we review our experience in using laparoscopy as a diagnostic and therapeutic tool in dealing with penetrating diaphragmatic injuries due to stab wounds and look at the feasibility of using this procedure in other similar institutions.Thirty patients, all of whom were males 20-30 years of age, presented to the surgical emergency unit of our hospital with upper abdominal and lower chest wall stab wounds between 01-05-1998 and 30-11-2006. Diagnosis of the diaphragm injury was either obvious with omentum herniating through the chest wall, or occult with confirmation of the injury at laparoscopy.All patients underwent diagnostic laparoscopy, which resulted in identification and efficient treatment of eight patients with diaphragmatic injury, and thereby laparotomy was avoided. The procedure converted to open surgery in one patient because of a small left-sided colonic tear. Laparoscopy is an efficient tool for the diagnosis and management of diaphragmatic injuries. It should be used routinely instead of exploratory laparotomy in haemodynamically stable patients with penetrating lower chest injuries.

Summary Background Hamartoma of the thoracic wall is a rare benign tumor that occurs in infancy and can be mistaken for a malignancy due to its clinical and imaging features. Hamartomas are extrapleural soft tissue lesions that cause rib expansion and destruction and appear on imaging as cystic areas with fluid levels and calcification. They can cause scoliosis, pressure on the neighboring lung parenchyma and mediastinal displacement. While conservative treatment is recommended in asymptomatic cases, growing lesions require surgical excision. Case Report In this report, we present the imaging findings in a 3-month-old infant that presented with a firm swelling in the chest wall and was histopathologically confirmed to have a bilateral multifocal hamartoma. Conclusions Radiological imaging methods are important for accurate diagnosis of this very rare condition that can be confused with a malignancy. PMID:26082822

The main aim of this study was to improve the quality of injury risk assessments in steering wheel rim to chest impacts when using the Hybrid III crash test dummy in frontal heavy goods vehicle (HGV) collision tests. Correction factors for chest injury criteria were calculated as the model chest injury parameter ratios between finite element (FE) Hybrid III, evaluated in relevant load cases, and the Total Human Model for Safety (THUMS). This is proposed to be used to compensate Hybrid III measurements in crash tests where steering wheel rim to chest impacts occur. The study was conducted in an FE environment using an FE-Hybrid III model and the THUMS. Two impactor shapes were used, a circular hub and a long, thin horizontal bar. Chest impacts at velocities ranging from 3.0 to 6.0 m/s were simulated at 3 impact height levels. A ratio between FE-Hybrid III and THUMS chest injury parameters, maximum chest compression C max, and maximum viscous criterion VC max, were calculated for the different chest impact conditions to form a set of correction factors. The definition of the correction factor is based on the assumption that the response from a circular hub impact to the middle of the chest is well characterized and that injury risk measures are independent of impact height. The current limits for these chest injury criteria were used as a basis to develop correction factors that compensate for the limitations in biofidelity of the Hybrid III in steering wheel rim to chest impacts. The hub and bar impactors produced considerably higher C max and VC max responses in the THUMS compared to the FE-Hybrid III. The correction factor for the responses of the FE-Hybrid III showed that the criteria responses for the bar impactor were consistently overestimated. Ratios based on Hybrid III and THUMS responses provided correction factors for the Hybrid III responses ranging from 0.84 to 0.93. These factors can be used to estimate C max and VC max values when the Hybrid III is

Full Text Available Abstract Background Low-grade extraskeletal osteosarcomas (ESOS are extremely rare. Case presentation We present the first case of low-grade ESOS of the chest wall, which occurred in a 30-year-old man. Because of initial misdiagnosis and patient's refusal of surgery, the diagnosis was done after a 4-year history of a slowly growing mass in soft tissues, leading to a huge (30-cm diameter calcified mass locally extended over the left chest wall. Final diagnosis was helped by molecular analysis of MDM2 and CDK4 oncogenes. Unfortunately, at this time, no surgical treatment was possible due to loco-regional extension, and despite chemotherapy, the patient died one year after diagnosis, five years after the first symptoms. Conclusion We describe the clinical, radiological and bio-pathological features of this unique case, and review the literature concerning low-grade ESOS. Our case highlights the diagnostic difficulties for such very rare tumours and the interest of molecular analysis in ambiguous cases.

Rib cage deformities alter respiratory muscle action and chest wall function in patients with severe osteogenesis imperfecta.

Directory of Open Access Journals (Sweden)

Antonella LoMauro

Full Text Available BACKGROUND: Osteogenesis imperfecta (OI is an inherited connective tissue disorder characterized by bone fragility, multiple fractures and significant chest wall deformities. Cardiopulmonary insufficiency is the leading cause of death in these patients. METHODS: Seven patients with severe OI type III, 15 with moderate OI type IV and 26 healthy subjects were studied. In addition to standard spirometry, rib cage geometry, breathing pattern and regional chest wall volume changes at rest in seated and supine position were assessed by opto-electronic plethysmography to investigate if structural modifications of the rib cage in OI have consequences on ventilatory pattern. One-way or two-way analysis of variance was performed to compare the results between the three groups and the two postures. RESULTS: Both OI type III and IV patients showed reduced FVC and FEV(1 compared to predicted values, on condition that updated reference equations are considered. In both positions, ventilation was lower in OI patients than control because of lower tidal volume (p<0.01. In contrast to OI type IV patients, whose chest wall geometry and function was normal, OI type III patients were characterized by reduced (p<0.01 angle at the sternum (pectus carinatum, paradoxical inspiratory inward motion of the pulmonary rib cage, significant thoraco-abdominal asynchronies and rib cage distortions in supine position (p<0.001. CONCLUSIONS: In conclusion, the restrictive respiratory pattern of Osteogenesis Imperfecta is closely related to the severity of the disease and to the sternal deformities. Pectus carinatum characterizes OI type III patients and alters respiratory muscles coordination, leading to chest wall and rib cage distortions and an inefficient ventilator pattern. OI type IV is characterized by lower alterations in the respiratory function. These findings suggest that functional assessment and treatment of OI should be differentiated in these two forms of the

While mandatory surgery for all thoracoabdominal penetrating injuries is advocated by some, the high rate of unnecessary operations challenges this approach. However, the consequences of intrathoracic bile remains poorly investigated. We sought to evaluate the outcome of patients who underwent non-operative management of right side thoracoabdominal (RST) penetrating trauma, and the levels of bilirubin obtained from those patients' chest tube effluent. We managed non-operatively all stable patients with a single RST penetrating injury. Chest tube effluent samples were obtained six times within (4-8 h; 12-16 h; 20-24 h; 28-32 h; 36-40 h; 48 h and 72 h) of admission for bilirubin measurement and blood for complete blood count, bilirubin, alanine (ALT) and aspartate aminotransferases (AST) assays. For comparison we studied patients with single left thoracic penetrating injury. Forty-two patients with RST injuries were included. All had liver and lung injuries confirmed by CT scans. Only one patient failed non-operative management. Chest tube bilirubin peaked at 48 h post-trauma (mean 3.3+/-4.1 mg/dL) and was always higher than both serum bilirubin (pchest tube effluent from control group (27 patients with left side thoracic trauma). Serum ALT and AST were higher in RST injury patients (ptrauma appears to be safe. Bile originating from the liver injury reaches the right thoracic cavity but does not reflect the severity of that injury. The highest concentration was found in the patient failing non-operative management. The presence of intrathoracic bile in selected patients who sustain RST penetrating trauma, with liver injury, does not preclude non-operative management. Our study suggests that monitoring chest tube effluent bilirubin may provide helpful information when managing a patient non-operatively.

Aging causes physiological and functional changes that impair pulmonary function. Incentive spirometry is widely used for lung expansion, but the effects of volume-oriented incentive spirometry (VIS) versus flow-oriented incentive spirometry (FIS) on chest wall volumes, inspiratory muscle activity, and thoracoabdominal synchrony in the elderly are poorly understood. We compared VIS and FIS in elderly subjects and healthy adult subjects. Sixteen elderly subjects (9 women, mean ± SD age 70.6 ± 3.9 y, mean ± SD body mass index 23.8 ± 2.5 kg/m(2)) and 16 healthy adults (8 women, mean ± age 25.9 ± 4.3 y, mean ± body mass index 23.6 ± 2.4 kg/m(2)) performed quiet breathing, VIS, and FIS in randomized sequence. Chest wall kinematics (via optoelectronic plethysmography) and inspiratory muscle activity (via surface electromyography) were assessed simultaneously. Synchrony between the superior thorax and abdominal motion was calculated (phase angle). In the elderly subjects both types of incentive spirometry increased chest wall volumes similarly, whereas in the healthy adult subjects VIS increased the chest wall volume more than did FIS. FIS and VIS triggered similar lower thoracoabdominal synchrony in the elderly subjects, whereas in the healthy adults FIS induced lower synchrony than did VIS. FIS required more muscle activity in the elderly subjects to create an increase in chest wall volume. Incentive spirometry performance is influenced by age, and the differences between elderly and healthy adults response should be considered in clinical practice.

Dependences of the mechanical properties of the respiratory system on frequency (f) and tidal volume (VT) in the normal ranges of breathing are not clear. We measured, simultaneously and in vivo, resistance and elastance of the total respiratory system (Rrs and Ers), lungs (RL and EL), and chest wall (Rcw and Ecw) of five healthy anesthetized paralyzed dogs during sinusoidal volume oscillations at the trachea (50-300 ml, 0.2-2 Hz) delivered at a constant mean lung volume. Each dog showed the same f and VT dependences. The Ers and Ecw increased with increasing f to 1 Hz and decreased with increasing VT up to 200 ml. Although EL increased slightly with increasing f, it was independent of VT. The Rcw decreased from 0.2 to 2 Hz at all VT and decreased with increasing VT. Although the RL decreased from 0.2 to 0.6 Hz and was independent of VT, at higher f RL tended to increase with increasing f and VT (i.e., as peak flow increased). Finally, the f and VT dependences of Rrs were similar to those of Rcw below 0.6 Hz but mirrored RL at higher f. These data capture the competing influences of airflow nonlinearities vs. tissue nonlinearities on f and VT dependence of the lung, chest wall, and total respiratory system. More specifically, we conclude that 1) VT dependences in Ers and Rrs below 0.6 Hz are due to nonlinearities in chest wall properties, 2) above 0.6 Hz, the flow dependence of airways resistance dominates RL and Rrs, and 3) lung tissue behavior is linear in the normal range of breathing.

Purpose: Electron beam radiotherapy of the chest wall with or without lymph node irradiation has been used at the Institut Curie for >20 years. The purpose of this report was to show the latest improvements of our technique developed to avoid hot spots and improve the homogeneity. Methods and Materials: The study was split into two parts. A new electron irradiation technique was designed and compared with the standard one (dosimetric study). The dose distributions were calculated using our treatment planning software ISIS (Technologie Diffusion). The dose calculation was performed using the same calculation parameters for the new and standard techniques. Next, the early skin toxicity of our new technique was evaluated prospectively in the first 25 patients using Radiation Therapy Oncology Group criteria (clinical study). Results: The maximal dose found on the five slices was 53.4 ± 1.1 Gy for the new technique and 59.1 ± 2.3 Gy for the standard technique. The hot spots of the standard technique plans were situated at the overlap between the internal mammary chain and chest wall fields. The use of one unique field that included both chest wall and internal mammary chain volumes solved the problem of junction. To date, 25 patients have been treated with the new technique. Of these patients, 12% developed Grade 0, 48% Grade 1, 32% Grade 2, and 8% Grade 3 toxicity. Conclusions: This report describes an improvement in the standard postmastectomy electron beam technique of the chest wall. This new technique provides improved target homogeneity and conformality compared with the standard technique. This treatment was well tolerated, with a low rate of early toxicity events

Trauma, especially chest and abdominal trauma are increasing due to the growing number of vehicles on the roads, which leads to an increased incidence of road accidents. Urbanization, industrialization and additional problems are the other associated factors which accelerate this phenomenon. A better understanding of the etiology and pattern of such injuries can help to improve the management and ultimate the outcomes of these patients. This study aimed to evaluate the patients with chest and abdominal trauma hospitalized in the surgery ward of Poursina teaching hospital, Guilan, Iran. In this cross-sectional study, the data of all chest and abdominal trauma patients hospitalized in the surgery ward of Poursina teaching hospital were collected from March 2011 to March 2012. Information about age, gender, injured areas, type of injury (penetrating or blunt), etiology of the injury, accident location (urban or rural) and patients' discharge outcomes were collected by a questionnaire. In total, 211 patients with a mean age of 34.1 ± 1.68 years was entered into the study. The most common cause of trauma was traffic accidents (51.7%). Among patients with chest trauma, 45 cases (35.4%) had penetrating injuries and 82 cases (64.6%) blunt lesions. The prevalence of chest injuries was 35.5% and rib fractures 26.5%. In chest injuries, the prevalence of hemothorax was 65.3%, pneumothorax 2.7%, lung contusion 4% and emphysema 1.3%, respectively. There were 24 cases (27.9%) with abdominal trauma which had penetrating lesions and 62 cases (72.1%) with blunt lesions. The most common lesions in patients with penetrating abdominal injuries were spleen (24.2%) and liver (12.1%) lesions. The outcomes of the patients were as follow: 95.7% recovery and 4.3% death. The majority of deaths were observed among road traffic victims (77.7%). Considering the fact that road-related accidents are quite predictable and controllable; therefore, the quality promotion of traumatic patients' care

The effects of non-invasive ventilation (NIV) on the breathing pattern and thoracoabdominal motion of patients with amyotrophic lateral sclerosis (ALS) are unknown. 1) To analyze the influence of NIV on chest wall volumes and motion assessed by optoelectronic plethysmography in ALS patients and 2) to compare these parameters in the supine and sitting positions to those of healthy individuals (without NIV). Nine ALS patients were evaluated in the supine position using NIV. In addition, the ALS patients and nine healthy individuals were evaluated in both sitting and supine positions. Statistical analysis was performed using the paired Student t-test or Wilcoxon test and the Student t-test for independent samples or Mann-Whitney U test. Chest wall volume increased significantly with NIV, mean volume=0.43 (SD=0.16)L versus 0.57 (SD=0.19)L (p=0.04). No significant changes were observed for the pulmonary rib cage, abdominal rib cage, or abdominal contribution. The index of the shortening velocity of the diaphragmatic muscle, mean=0.15 (SD=0.05)L/s versus 0.21 (SD=0.05)L/s (pNIV. Comparisons between the supine and sitting positions showed similar changes in chest wall motion in both groups. However, the ALS patients presented a significantly lower contribution of the abdomen in the supine position compared with the controls, mean=56 (SD=13) versus 69 (SD=10) (p=0.02). NIV improved chest wall volumes without changing the contribution of the chest wall compartment in ALS patients. In the supine position, ALS patients had a lower contribution of the abdomen, which may indicate early diaphragmatic dysfunction.

Purpose: To review the 40-year University of Florida experience treating Ewing sarcoma family of tumors of the chest wall. Methods and Materials: Thirty-nine patients were treated from 1966 to 2006. Of the patients, 22 were treated with radiotherapy (RT) alone, and 17 patients were treated with surgery with or without RT. Of 9 patients with metastatic disease, 8 were treated with RT alone. The risk profiles of each group were otherwise similar. The median age was 16.6 years, and the most frequent primary site was the rib (n = 17). The median potential follow-up was 19.2 years. Results: The 5-year actuarial overall survival (OS), cause-specific survival (CSS), and local control (LC) rates were 34%, 34%, and 72%, respectively. For the nonmetastatic subset (n = 30), the 5-year OS, CSS, and LC rates were 44%, 44%, and 79%, respectively. LC was not statistically significantly different between patients treated with RT alone (61%) vs. surgery + RT (75%). None of the 4 patients treated with surgery alone experienced local failure. No patient or treatment variable was significantly associated with local failure. Of the patients, 26% experienced Common Toxicity Criteria (CTC) Grade 3+ toxicity, including 2 pulmonary deaths. Modern intensive systemic therapy helped increase the 5-year CSS from 7% to 49% in patients treated after 1984 (p = 0.03). Conclusions: This is the largest single-institution series describing the treatment of chest wall Ewing tumors. Despite improvements in survival, obtaining local control is challenging and often accompanied by morbidity. Effort should be focused on identifying tumors amenable to combined-modality local therapy and to improving RT techniques.

Extrinsic airway compression due to chest wall deformity is not commonly observed. Although this condition can be diagnosed more easily with the help of multidetector CT, the standard treatment method has not yet been definitely established. We report a case of an eighteen-year-old male who suffered from severe extrinsic tracheal compression due to scoliosis and straightening of the thoracic spine, confirmed on CT and bronchoscopy. The patient underwent successful placement of tracheal stent but later died of bleeding from the tracheostomy site probably due to tracheo-brachiocephalic artery fistula. We describe the CT and bronchoscopic findings of extrinsic airway compression due to chest wall deformity as well as the optimal treatment method, and discuss the possible explanation for bleeding in the patient along with review of the literature.

Purpose: The voluntary breath-hold (BH) technique is a simple method to control the respiration-related motion of a tumor during irradiation. However, the abdominal and chest wall position may not be accurately reproduced using the BH technique. The purpose of this study was to examine whether visual feedback can reduce the fluctuation in wall motion during BH using a new respiratory monitoring device. Methods and Materials: We developed a laser-based BH monitoring and visual feedback system. For this study, five healthy volunteers were enrolled. The volunteers, practicing abdominal breathing, performed shallow end-expiration BH (SEBH), shallow end-inspiration BH (SIBH), and deep end-inspiration BH (DIBH) with or without visual feedback. The abdominal and chest wall positions were measured at 80-ms intervals during BHs. Results: The fluctuation in the chest wall position was smaller than that of the abdominal wall position. The reproducibility of the wall position was improved by visual feedback. With a monitoring device, visual feedback reduced the mean deviation of the abdominal wall from 2.1 ± 1.3 mm to 1.5 ± 0.5 mm, 2.5 ± 1.9 mm to 1.1 ± 0.4 mm, and 6.6 ± 2.4 mm to 2.6 ± 1.4 mm in SEBH, SIBH, and DIBH, respectively. Conclusions: Volunteers can perform the BH maneuver in a highly reproducible fashion when informed about the position of the wall, although in the case of DIBH, the deviation in the wall position remained substantial

Blunt thoracic trauma is one of the critical injury mechanisms in multiply injured trauma victims. Although these patients present a plethora of potential structural damages to vital organs, it remains debated which injuries actually influence outcome and thereby should be addressed initially. Hence, the aim of this study was to identify the influence of critical structural damages on mortality. All patients in the database of the TraumaRegister DGU® (TR-DGU) from 2002-2011 with AIS Chest ≥ 2, blunt trauma, age of 16 or older and an ISS ≥ 16 were analyzed. Outcome parameters were in-hospital mortality as well as ventilation time in patients surviving the initial 14 days after trauma. 22613 Patients were included (mean ISS 30.5 ± 12.6; 74.7% male; Mean Age 46.1 ± 197 years; mortality 17.5%; mean duration of ventilation 7.3 ± 11.5; mean ICU stay 11.7 ± 14.1 days). Only a limited number of specific injuries had a significant impact on survival. Major thoracic vessel injuries (AIS ≥5), bilateral lung contusion, bilateral flail chest, structural heart injury (AIS ≥3) significantly influence mortality in study patients. Several extrathoracic factors (age, blood transfusion, systolic blood pressure and extrathoracic severe injuries) were also predictive of increased mortality. Most injuries of the thoracic wall had no or only a moderate effect on the duration of ventilation. Injuries to the lung (laceration, contusion or pneumothoraces) had a moderate prolonging effect. Cardiac injuries and severe injuries to the thoracic vessels induced a substantially prolonged ventilation interval. We demonstrate quantitatively the influence of specific structural damages of the chest on critical outcome parameters. While most injuries of the chest wall have no or only limited impact in the study collective, injuries to the lung overall show adverse outcome. Injuries to the heart or thoracic vessels have a devastating prognosis following blunt

The aim of the present study was to assess how volume-oriented incentive spirometry applied to patients after a stroke modifies the total and compartmental chest wall volume variations, including both the right and left hemithoraces, compared with controls. Twenty poststroke patients and 20 age-matched healthy subjects were studied by optoelectronic plethysmography during spontaneous quiet breathing (QB), during incentive spirometry, and during the recovery period after incentive spirometry. Incentive spirometry was associated with an increased chest wall volume measured at the pulmonary rib cage, abdominal rib cage and abdominal compartment (P = .001) and under 3 conditions (P spirometry, and postincentive spirometry, respectively. Under all 3 conditions, the contribution of the abdominal compartment to VT was greater in the stroke subjects (54.1, 43.2, and 48.9%) than in the control subjects (43.7, 40.8, and 46.1%, P = .039). In the vast majority of subjects (13/20 and 18/20 during QB and incentive spirometry, respectively), abdominal expansion precedes rib cage expansion during inspiration. Greater asymmetry between the right and left hemithoracic expansions occurred in stroke subjects compared with control subjects, but it decreased during QB (62.5%, P = .002), during incentive spirometry (19.7%), and postincentive spirometry (67.6%, P = .14). Incentive spirometry promotes increased expansion in all compartments of the chest wall and reduces asymmetric expansion between the right and left parts of the pulmonary rib cage; therefore, it should be considered as a tool for rehabilitation.

Purpose: Long-term outcome after radiation therapy for local-regional recurrence of breast cancer after mastectomy is generally poor. This study was performed to evaluate the long-term outcome for a potentially favorable subgroup of patients with chest wall recurrence. Methods and Materials: Of 71 patients with an isolated local-regional recurrence of breast cancer after mastectomy, 18 were identified who met the following favorable selection criteria: 1) a disease-free interval after mastectomy of 2 years or more, 2) an isolated chest wall recurrence, and 3) tumor size < 3 cm or complete excision of the recurrent disease. All 18 patients were treated with local-regional irradiation between 1967 and 1988. Radiotherapy (RT) was delivered to the chest wall to a median total dose of 60 Gy (range 30-66 Gy). Four patients received adjuvant chemotherapy and six patients received adjuvant hormonal therapy. Results: With a median follow-up of 8.4 years, nine of 18 patients were alive and free of disease. The 10-year actuarial overall and cause-specific survivals were 72% and 77%, respectively. The 10-year actuarial relapse-free survival and local control were 42% and 86%, respectively. Conclusion: Treatment for a local-regional recurrence of breast cancer after mastectomy in a favorable subgroup of patients results in a high rate of long-term survival as well as excellent local control. Aggressive treatment is warranted in this favorable subgroup of patients. 1998 Elsevier Science Inc

Fifty consecutive patients with radiation-related problems of the chest wall were treated between 1976 and 1984. There were 40 women and 10 men with an average age of 54 years (range 26 to 78 years). Twenty-three patients had radiation ulcers alone, 20 had recurrent cancer, and 7 had infected median sternotomy wounds. Thirty-six had skeletal resections and 44 had soft-tissue resections. The skeleton was reconstructed with Prolene mesh in 12 patients and with autogenous rib in 3. Sixty-three muscles were transposed in 43 patients. Twelve omental transpositions were performed (8 for primary treatment and 4 for salvage of a failed muscle flap). Hospitalization averaged 20.2 days. There was one operative death (at 29 days). Partial flap necrosis occurred in 10 patients. Mesh was removed in three patients. There were 14 late deaths, most from recurrent tumor. The remaining patients had well-healed wounds and a generally improved quality of life. We conclude that aggressive resection and reliable reconstruction are critical considerations in the surgical management of this perplexing clinical problem

Thoracic injuries are potentially responsible for 25% of all trauma deaths. Chest X-ray is commonly used to screen patients with chest injury. However, the use of computed tomography (CT) scan for primary screening is increasing, particularly for blunt trauma. CT scans are more sensitive than chest X-ray in detecting intra-thoracic abnormalities such as pneumothoraces and pneumomediastinums. Pneumomediastinum detected by chest X-ray or "overt pneumomediastinum", raises the concern of possible aerodigestive tract injuries. In contrast, there is scarce information on the clinical significance of pneumomediastinum diagnosed by CT scan only or "occult pneumomediastinum". Therefore we investigated the clinical consequences of occult pneumomediastinum in our blunt trauma population. A 2-year retrospective chart review of all blunt chest trauma patients with initial chest CT scan admitted to a level I trauma centre. Data extracted from the medical records include; demographics, occult, overt, or no pneumomediastinum, the presence of intra-thoracic aerodigestive tract injuries (trachea, bronchus, and/or esophagus), mechanism and severity of injury, endotracheal intubation, chest thoracostomy, operations and radiological reports by an attending radiologist. All patients with intra-thoracic aerodigestive tract injuries from 1994 to 2004 were also investigated. Of 897 patients who met the inclusion criteria 839 (93.5%) had no pneumomediastinum. Five patients (0.6%) had overt pneumomediastinum and 53 patients (5.9%) had occult pneumomediastinum. Patients with occult pneumomediastinum had significantly higher ISS and AIS chest (pchest thoracostomy tube was more common (ppneumothorax. None of the patients with occult pneumomediastinum had aerodigestive tract injuries (95%CI 0-0.06). Follow up CT scan of patients with occult pneumomediastinum showed complete resolution in all cases, in average 3 h after the initial exam. Occult pneumomediastinum occurred in approximately 6% of

This paper evaluates the influence of MR detection of additional sites of chest lymphoma on radiation therapy. Chest MR images and CT scans of 56 patients with new or recurrent mediastinal lymphoma obtained within 1 month of each other were retrospectively reviewed. MR images included T1- and T2-weighted SE and STIR sequences. Images were assessed for pleural and extrapleural disease. Radiation portals of patients with pleural or chest wall disease were reevaluated and compared with portals originally designed with CT. MR imaging demonstrated chest wall disease in 15 patients (21 sites). Ten patients also had pleural disease (13 sites). CT identified chest wall disease in four of these patients (five sites) and pleural disease in three patients (five sites). Seven of the 15 patients with chest wall disease were treated with radiation therapy alone. Two of the seven patients had significant modification of radiation portals based on MR findings. Retrospectively, therapy would have been altered in an additional two patients in whom pleural disease was identified at MR. The increased sensitivity of MR in detecting chest wall or pleural disease has important implications for treatment planning in chest wall lymphoma

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)

Multidetector CT of blunt traumatic venous injuries in the chest, abdomen, and pelvis.

Holly, Brian P; Steenburg, Scott D

2011-01-01

Venous injuries as a result of blunt trauma are rare. Even though current protocols for multidetector computed tomography (CT) of patients with trauma are designed to evaluate primarily the solid organs and arteries, blunt venous injuries may nevertheless be identified, or at least suspected, on the basis of the multidetector CT findings. Venous injuries are associated with high morbidity and mortality rates. Diagnosis of a possible venous injury is crucial because the physical findings of a venous injury are nonspecific and may be absent. This article aims to make the radiologist aware of various venous injuries caused by blunt trauma and to provide helpful hints to aid in the identification of venous injuries. Multidetector CT technology, in combination with interactive manipulation of the raw dataset, can be useful in the creation of multiplanar reconstructed images and in the identification of a venous injury caused by blunt trauma. Familiarity with direct and indirect signs of venous injuries, as well as with examples of blunt traumatic venous injuries in the chest, abdomen, and pelvis, will help in the diagnosis of these injuries.

Primary malignant chest wall tumors are rare. The most frequent primary malignant tumor of the chest wall is chondrosarcoma, less common are primary bone tumors belonging to the Ewing Family Bone Tumors (EFBT), or even rarer are osteosarcomas. They represent a challenging clinical entities for surgeons as the treatment of choice for these neoplasms is surgical resection, excluding EFBT which are normally treated by a multidisciplinary approach. Positive margins after surgical procedure are the principal risk factor of local recurrence, therefore to perform adequate surgery a correct preoperative staging is mandatory. Imaging techniques are used for diagnosis, to determine anatomic site and extension, to perform a guided biopsy, for local and general staging, to evaluate chemotherapy response, to detect the presence of a recurrence. This article will focus on the role of imaging in guiding this often difficult surgery and the different technical possibilities adopted in our department to restore the mechanics of the thoracic cage after wide resections.

Traumatic ventricular septal defect in a 4-year-old boy after blunt chest injury

Directory of Open Access Journals (Sweden)

Yun Mi Kim

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.

Extensive chest wall defect reconstruction remains a challenging problem for surgeons. In the past several years, little progress has been made in this area. In this study, a biodegradable polydioxanone (PDO) mesh and demineralized bone matrix (DBM) seeded with osteogenically induced bone marrow stromal cells (BMSCs) were used to reconstruct a 6 cm x 5.5 cm chest wall defect. Four experimental groups were evaluated (n=6 per group): polydioxanone (PDO) mesh/DBMs/BMSCs group, polydioxanone (PDO) mesh/DBMs group, polydioxanone (PDO) mesh group, and a blank group (no materials) in a canine model. All the animals survived except those in the blank group. In all groups receiving biomaterial implants, the polydioxanone (PDO) mesh completely degraded at 24 weeks and was replaced by fibrous tissue with thickness close to that of the normal intercostal tissue (P>0.05). In the polydioxanone (PDO) mesh/DBMs/BMSCs group, new bone formation and bone-union were observed by radiographic and histological examination. More importantly, the reconstructed rib could maintain its original radian and achieve satisfactory biomechanics close to normal ribs in terms of bending stress (P>0.05). However, in the other two groups, fibrous tissue was observed in the defect and junctions, and the reconstructed ribs were easily distorted under an outer force. Based on these results, a surgical approach utilizing biodegradable polydioxanone (PDO) mesh in combination with DBMs and BMSCs could repair the chest wall defect not only in function but also in structure.

Simultaneous measurement of instantaneous heart rate and chest wall plethysmography in short-term, metronome guided heart rate variability studies: suitability for assessment of autonomic dysfunction.

Science.gov (United States)

Perring, S; Jones, E

2003-08-01

Instantaneous heart rate and chest wall motion were measured using a 3-lead ECG and an air pressure chest wall plethysmography system. Chest wall plethysmography traces were found to accurately represent the breathing pattern as measured by spirometry (average correlation coefficient 0.944); though no attempt was made to calibrate plethysmography voltage output to tidal volume. Simultaneous measurements of heart rate and chest wall motion were made for short periods under metronome guided breathing at 6 breaths per minute. The average peak to trough heart rate change per breath cycle (AVEMAX) and maximum correlation between heart rate and breathing cycle (HRBRCORR) were measured. Studies of 44 normal volunteers indicated clear inverse correlation of heart rate variability parameters with age (AVEMAX R = -0.502, P < 0.001) but no significant change in HRBRCORR with age (R = -0.115). Comparison of normal volunteers with diabetics with no history of symptoms associated with autonomic failure indicated significant lower heart rate variability in diabetics (P = 0.005 for AVEMAX) and significantly worse correlation between heart rate and breathing (P < 0.001 for HRBRCORR). Simultaneous measurement of heart rate and breathing offers the possibility of more sensitive diagnosis of autonomic failure in a simple bedside test and gives further insight into the nature of cardio-ventilatory coupling.

A Case of “en bloc” Excision of a Chest Wall Leiomyosarcoma and Closure of the Defect with Non-Cross-Linked Collagen Matrix (Egis®

Full Text Available Sarcomas arising from the chest wall account for less than 20% of all soft tissue sarcomas, and at this site, primitive tumors are the most frequent to occur. Leiomyosarcoma is a malignant smooth muscle tumor and the best outcomes are achieved with wide surgical excision. Although advancements have been made in treatment protocols, leiomyosarcoma remains one of the more difficult soft tissue sarcoma to treat. Currently, general local control is obtained with surgical treatment with wide negative margins. We describe the case of a 50-year-old man who underwent a chest wall resection involving a wide portion of the pectoralis major and minor muscle, the serratus and part of the second, third and fourth ribs of the left side. The full-thickness chest wall defect of 10 × 8 cm was closed using a non-cross-linked acellular dermal matrix (Egis® placed in two layers, beneath the rib plane and over it. A successful repair was achieved with no incisional herniation and with complete tissue regeneration, allowing natural respiratory movements. No complications were observed in the postoperative course. Biological non-cross-linked matrix, derived from porcine dermis, behaves like a scaffold supporting tissue regeneration; it can be successfully used as an alternative to synthetic mesh for chest wall reconstruction.

A 75 years old man went to the Carlos Andrade Marin Hospital due to the appearance of a mass on his chest wall, initially diagnosed as a lypoma. During his preoperative preparation we had a suspicion of a malignant process. Finally and after a surgical procedure the diagnose was made, breast cancer. Considered this way the practice of medicine is as simple as having a suspicion. In fact it is, actually what determines the final diagnose of a pathology is the suspicion that we as physicians have about a problem. However, to generate an hypothesis we required knowledge, study and curiosity. The present work is a bibliographic review about a non so frequent problem as the thoracic mass is. The author)

Computed tomography (CT) has been shown to detect more injuries than plain radiography in patients with blunt trauma, but it is unclear whether these injuries are clinically significant. This study aimed to determine the proportion of patients with normal chest x-ray (CXR) result and injury seen on CT and abnormal initial CXR result and no injury on CT and to characterize the clinical significance of injuries seen on CT as determined by a trauma expert panel. Patients with blunt trauma older than 14 years who received emergency department chest imaging as part of their evaluation at 2 urban level I trauma centers were enrolled. An expert trauma panel a priori classified thoracic injuries and subsequent interventions as major, minor, or no clinical significance. Of 3639 participants, 2848 (78.3%) had CXR alone and 791 (21.7%) had CXR and chest CT. Of 589 patients who had chest CT after a normal CXR result, 483 (82.0% [95% confidence interval [CI], 78.7-84.9%]) had normal CT results, and 106 (18.0% [95% CI, 15.1%-21.3%]) had CTs diagnosing injuries-primarily rib fractures, pulmonary contusion, and incidental pneumothorax. Twelve patients had injuries classified as clinically major (2.0% [95% CI, 1.2%-3.5%]), 78 were clinically minor (13.2% [95% CI, 10.7%-16.2%]), and 16 were clinically insignificant (2.7% (95% CI, 1.7%-4.4%]). Of 202 patients with CXRs suggesting injury, 177 (87.6% [95% CI, 82.4%-91.5%]) had chest CTs confirming injury and 25 (12.4% [95% CI, 8.5%-17.6%]) had no injury on CT. Chest CT after a normal CXR result in patients with blunt trauma detects injuries, but most do not lead to changes in patient management. Copyright © 2013 Elsevier Inc. All rights reserved.

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 Abstract Background Raoultella planticola was originally considered to be a member of environmental Klebsiella. The clinical significance of R. planticola is still not well known. Case presentation We describe the first case of necrotizing fasciitis involving the chest and abdominal wall caused by R. planticola. The identity of the organism was confirmed using 16S rRNA sequencing. The patient was successfully treated with the appropriate antibiotics combined with operative drainage and debridement. Conclusions R. planticola had been described as environmental species, but should be suspected in extensive necrotizing fasciitis after minor trauma in mild to moderate immunocompromised patients.

A case of radiation ulcer of chest wall with osteomyelitis

We report a case of anterior chest skin ulcer with rib and sternum osteomyelitis following radiation therapy for post operative mammary carcinoma. Operation was performed six times including debridement with sternum and rib resection reconstruction and skin grafting. It took about one and a half years after first operation to heal the ulcer with osteomyelitis. Principle of treatment for radiation ulcer accompanied by osteomyelitis is complete resection of the damaged lesion. However, it is difficult to evaluate the exact area of the damaged lesion. Therefore it is not rare to repeat its recurrence and have trouble with its treatment. In this case, it was considered that the resected area was insufficient on the initial operation. In order to treat for radiation ulcers accompanied by osteomyelitis, enough resection of the damaged lesion in the initial operation is necessary. Ultimately, in our case, the resection of all sternum, part of the right second to fifth rib and part of left second to seventh rib was necessary. It is generally said that reconstructing bone structure is required in the case of wide defect of chest wall. Though, we did not perform reconstruction of the bone structures, there is no problem in the condition of respiratory system. The surrounding soft tissues changed to hard enough to avoid paradoxical breathing. (author)

We retrospectively analyzed (January 2010 to December 2014) 27 consecutive patients (22 males, 5 females; range 16-83 years, median age 60 years), treated with this system: primary [3] and secondary [8] chest wall tumor; flail chest [5]; multiple ribs fractures [5]; sternal dehiscence-diastasis [3]; sternal fracture [1]; sternoclavicular joint dislocation [1]; Poland syndrome [1]. Short-term results were evaluated as: operating time, post-operative morbidity, mortality, hospital stay; long-term results as: survival, plates-related morbidity, spirometric values, chest pain [measured with Verbal Rating Scale (VRS) and SF12 standard V1 questionnaire]. Each patient received from 1 to 10 (median 2) titanium plates/splints; median operating time was 150 min (range: 115-430 min). Post-operative course: 15 patients (55.6%) uneventful, 10 (37%) minor complications, 2 (7.4%) major complications; no post-operative mortality. Median post-operative hospital stay was 13 days (range: 5-129 days). At a median follow-up of 20 months (range: 1-59 months), 21 patients (78%) were alive, 6 (22%) died. Three patients presented long-term plates-related morbidity: plates rupture [2], pin plate dislodgment [1]; two required a second surgical look. One-year from surgery median spirometric values were: FVC 3.31 L (90%), FEV1 2.46 L (78%), DLCO 20.9 mL/mmHg/min (76%). On 21 alive patients, 7 (33.3%) reported no pain (VRS score 0), 10 (47.6%) mild (score 2), 4 (19.1%) moderate (score 4), no-one severe (score >4); 15 (71.5%) reported none or mild, 6 (28.5%) moderate pain influencing quality of life. An optimal chest wall stabilization and reconstruction was achieved with the Synthes(®) titanium plates system, with minimal morbidity, no post-operative mortality, acceptable operating time and post-operative hospital stay.

Computed tomography (CT) of the chest (chest CT) is overused in blunt pediatric thoracic trauma. Chest CT adds to the diagnosis of thoracic injury but rarely changes patient management. We sought to identify a subset of blunt pediatric trauma patients who would benefit from a screening chest CT based on their admission chest x-ray (CXR) findings. We hypothesize that limiting chest CT to patients with an abnormal mediastinal silhouette identifies intrathoracic vascular injuries not otherwise seen on CXR. All blunt trauma activations that underwent an admission CXR at our Level 1 pediatric trauma center from 2005 to 2013 were retrospectively reviewed. Patients who had a chest CT were evaluated for added diagnoses and change in management after CT. An admission CXR was performed in 1,035 patients. One hundred thirty-nine patients had a CT, and the diagnosis of intra-thoracic injury was added in 42% of patients. Chest CT significantly increased the diagnosis of contusion or atelectasis (30.3% vs 60.4%; p pneumothorax (7.2% vs 18.7%; p chest CT. Chest CT changed the management of only 4 patients (2.9%). Two patients underwent further radiologic evaluation that was negative for injury, one had a chest tube placed for an occult pneumothorax before exploratory laparotomy, and one patient had a thoracotomy for repair of aortic injury. Chest CT for select patients with an abnormal mediastinal silhouette on CXR would have decreased CT scans by 80% yet still identified patients with an intrathoracic vascular injury. The use of chest CT should be limited to the identification of intrathoracic vascular injuries in the setting of an abnormal mediastinal silhouette on CXR.

Purpose: This work presents an algorithm used to quantify intra-fraction motion for patients treated using deep inspiration breath hold (DIBH). The algorithm quantifies the position of the chest wall in breast tangent fields using electronic portal images. Methods: The algorithm assumes that image profiles, taken along a direction perpendicular to the medial border of the field, follow a monotonically and smooth decreasing function. This assumption is invalid in the presence of lung and can be used to calculate chest wall position. The algorithm was validated by determining the position of the chest wall for varying field edge positions in portal images of a thoracic phantom. The algorithm was used to quantify intra-fraction motion in cine images for 7 patients treated with DIBH. Results: Phantom results show that changes in the distance between chest wall and field edge were accurate within 0.1 mm on average. For a fixed field edge, the algorithm calculates the position of the chest wall with a 0.2 mm standard deviation. Intra-fraction motion for DIBH patients was within 1 mm 91.4% of the time and within 1.5 mm 97.9% of the time. The maximum intra-fraction motion was 3.0 mm. Conclusions: A physics based algorithm was developed and can be used to quantify the position of chest wall irradiated in tangent portal images with an accuracy of 0.1 mm and precision of 0.6 mm. Intra-fraction motion for patients treated with DIBH at our clinic is less than 3 mm.

Full Text Available 【Abstract】 Objective: Thoracic injuries are respon- sible for 25% of deaths of blunt traumas. Chest X-ray (CXR is the first diagnostic method in patients with blunt trauma. The aim of this study was to detect the accuracy of CXR versus chest computed tomograpgy (CT in hemodynami- cally stable patients with blunt chest trauma. Methods: Study was conducted at the emergency department of Sina Hospital from March 2011 to March 2012. Hemodynamically stable patients with at least 16 years of age who had blunt chest trauma were included. All patients underwent the same diagnostic protocol which consisted of physical examination, CXR and CT scan respectively. Results: Two hundreds patients (84% male and 16% female were included with a mean age of (37.9±13.7 years. Chin J Traumatol 2013;16(6:351-354 Rib fracture was the most common finding of CXR (12.5% and CT scan (25.5%. The sensitivity of CXR for hemothorax, thoracolumbar vertebra fractures and rib fractures were 20%, 49% and 49%, respectively. Pneumothorax, foreign body, emphysema, pulmonary contusion, liver hematoma and ster- num fracture were not diagnosed with CXR alone. Conclusion: Applying CT scan as the first-line diag- nostic modality in hemodynamically stable patients with blunt chest trauma can detect pathologies which may change management and outcome.

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.)

This paper describes the skin cancer on the frontal chest wall induced by postoperative irradiation 30 years later from mastectomy. The patients was a 62-year-old woman, who received mastectomy of the right breast cancer (invasive ductal carcinoma, comedo type) at 31 years old, and received the postoperative radiotherapy of total 11,628 rad over 38 times. On the first medical examination in author`s hospital, the patient had an ulcer of about 10 cm diameter and was diagnosed the radiation induced skin cancer (well differentiated squamous cell carcinoma) in the biopsy. Because of the general condition of the patient was extremely bad and the skin cancer had highly developed, the excision was thought to be impossible. The radiotherapy (16 Gy) and combined local chemotherapy by OK 432 and Bleomycin were performed. In spite of the short term treatment, these therapies were effective on the reduction of the tumor size and the hemostasis, and brought the patient the improvement of QOL. The general condition of the patient improved to be stable and she recovered enough to go out from the hospital for 6 months. After 10 months, she showed anorexia and dyspnea and died after about 1 year from the admission. The present case is extremely rare, and it is required the radical therapy like the excision of chest wall at early stage. (K.H.)

Blunt thoracic aortic injuries (BTAI) have a high mortality rate. For survivors, chest X-ray (CXR) findings are used to determine the need for further diagnostic testing with chest computerized tomography with angiography (CTA) or conventional angiography. We set to determine the adequacy of utilizing CXR alone as a screening tool for BTAI. All patients diagnosed with BTAI at a level I trauma-center during a 7-year-period were identified. CXRs of these patients and those of a control group of blunt trauma patients with an injury severity score >15 were reviewed by four trauma surgeons blinded to the diagnosis. Based on each CXR viewed, the surgeons decided if they would have proceeded to chest CTA, angiography, or required no further studies to rule out BTAI. In the 7-year-period, 83 patients had BTAI. CXRs were available in 45 patients. The four surgeons viewed 96 CXRs including those of 51 controls. Based on the CXR appearance in patients with BTAI, the surgeons chose to proceed to chest CTA in 38 patients (84.4%), conventional aortography in two patients (4.4%), and no further testing in five patients (11.2%). A widened mediastinum (75%) and loss of the aorto-pulmonary window (40%) were the most frequent CXR abnormalities. Patients with BTAI were more likely to have an abnormal CXR-40 of 45 (88.8%) patients when compared with the controls-25 of 51 (49%)patients-p < 0.001. Although CXR is a sensitive screening modality, it failed to identify the possibility of BTAI in 11% of patients. The liberal use of chest CTA after high speed motor vehicle crashes is recommended to minimize the incidence of missed BTAI.

Objectives To review the need for operative intervention and critical care services for motocross truncal injuries in children. Design cohort Retrospective review of patients identified via the hospital trauma registry. Setting Our Level 1 Pediatric Trauma Center serves five motocross tracks. These patients require frequent medical care for injuries. Participants All patients ≤17 years of age with truncal injuries sustained during motocross activities, between 2000 and 2011, were identified through the trauma registry. Primary and secondary outcome measures Operative intervention, intensive care unit (ICU) admission, length of stay, morbidity and demographics were reviewed. Results Motocross injured 162 children. Thirty (18.5%) were thoracic or abdominal injuries. Operative intervention was required in eight (27%) patients. Mean injury severity score (ISS) was 11.8. ICU admission was required in 50% and average hospital length of stay was 4.1 days. The most common injuries include pulmonary contusion, pneumothorax, spleen and liver lacerations. 13% of subjects suffered truncal injury from motocross on more than one occasion. Conclusions Paediatric motocross-related truncal injuries are significant. Surgical intervention is required in 27% of patients. The lower ISS incurred from motocross combined with high surgical and ICU admission rates suggests focal high-impact injuries to the chest and abdomen. Despite significant injury, 13% of motocross patients suffer recurrent injuries. Parents and children need injury prevention education. PMID:23166134

Trauma is the third leading cause of death, irrespective of age, and the leading cause of death in persons under 40 persons under 40 years of age. Most pleural, pulmonary, mediastinal, and diaphragmatic injuries are not seen on conventional chest radiographs, or are underestimated. In patients with chest trauma, CT scanning is an effective and sensitive method of detecting thoracic injuries and provides accurate information regarding their pattern and extent.

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. Due to the pliability of the pediatric rib cage and mediastinal mobility, significant intrathoracic injury may exist in the

Pulmonary chronic graft-versus-host disease (cGvHD) is one of the most common causes of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (aHSCT). Herein, we describe a patient with severe restrictive lung defect secondary to cGvHD. A 21-year-old male patient was admitted to our pediatric intensive care unit (PICU) with pneumonia and respiratory distress. He had a history of aHSCT for chronic myelogeneous leukemia at the age of 17 years. Six months after undergoing aHSCT, he had developed cGvHD involving skin, mouth, eye, lung, liver, and gastrointestinal tract. At the time of PICU admission he had respiratory distress and required ventilation support. Thorax high-resolution computed tomography was consistent with bronchiolitis obliterans. Although bronchiolitis obliterans is an obstructive lung defect, a restrictive pattern became prominent in the clinical course because of the sclerotic chest wall skin. The activity of cGvHD kept increasing despite the therapy and we lost the patient because of severe respiratory distress and massive hemoptysis secondary to bronchiectasis. In conclusion, pulmonary cGvHD can present with restrictive changes related with the advanced sclerosis of the chest wall skin. Performing a fasciotomy or a scar revision for the rigid chest wall in selected patients may improve the patients ventilation.

We present the case of a patient who sustained a penetrating injury to the chest caused by an attenuated energy rubber bullet and review the literature on thoracic injuries caused by plastic and rubber "less-lethal" munitions. The patient of this report underwent a right thoracotomy to extract the projectile as well as a wedge resection of the injured lung parenchyma. This case demonstrates that even supposedly safe riot control munition fired at close range, at the torso, can provoke serious injury. Therefore a thorough investigation and close clinical supervision are justified.

Blunt chest trauma is a significant source of morbidity and mortality in industrialized countries. The clinical presentation of trauma patients varies widely from one individual to another and ranges from minor reports of pain to shock. Knowledge of the mechanism of injury, the time of injury, estimates of motor vehicle accident velocity and deceleration, and evidence of associated injury to other systems are all salient features to provide for an adequate assessment of chest trauma. Multi-detector row computed tomography (MDCT) scanning and MDCT-angiography are being used more frequently in the diagnosis of patients with chest trauma. The high sensitivity of MDCT has increased the recognized spectrum of injuries. This new technology can be regarded as an extremely valuable adjunct to physical examination to recognize suspected and unsuspected blunt chest trauma

Abstract Pneumothorax is a common complication following blunt chest wall trauma. In these patients, because of the restrictions regarding immobilization of the cervical spine, Anteroposterior (AP) chest radiograph is usually the most feasible initial study which is not as sensitive as the erect chest X-ray or CT chest for detection of a pneumothorax. We will present 3 case reports which serve for better understanding of the entity of occult pneumothorax. The first case is an example of a tru...

Chest computed tomography (CCT) is used to screen for injuries in hemodynamically stable patients with penetrating injury. We aim to determine the incidence of missed injuries detected on CCT after a negative chest radiograph (CXR) in patients with thoracic stab wounds. A 10-year retrospective review of a Level I trauma center registry was performed on patients with thoracic stab wounds. Patients who were hemodynamically unstable or did not undergo both CXR and CCT were excluded. Patients with a negative CXR were evaluated to determine if additional findings were diagnosed on CCT. Of 386 patients with stab wounds to the chest, 154 (40%) underwent both CXR and CCT. One hundred and fifteen (75%) had a negative screening CXR. CCT identified injuries in 42 patients (37%) that were not seen on CXR. Pneumothorax and/or hemothorax occurred in 40 patients (35%), of which 14 patients underwent tube thoracostomy. Two patients had hemopericardium on CCT and both required operative intervention. Greater than one-third of patients with a normal screening CXR were found to have abnormalities on CCT. Future studies comparing repeat CXR to CCT are required to further define the optimal diagnostic strategy in patients with stab wounds to chest after normal screening CXR.

The use of chest computed tomography (CT) to evaluate emergency department patients with adult blunt trauma is rising. The NEXUS Chest CT decision instruments are highly sensitive identifiers of adult blunt trauma patients with thoracic injuries. However, many patients without injury exhibit one of more of the criteria so cannot be classified "low risk." We sought to determine screening performance of both individual and combined NEXUS Chest CT criteria as predictors of thoracic injury to inform chest CT imaging decisions in "non-low-risk" patients. This was a secondary analysis of data on patients in the derivation and validation cohorts of the prospective, observational NEXUS Chest CT study, performed September 2011 to May 2014 in 11 Level I trauma centers. Institutional review board approval was obtained at all study sites. Adult blunt trauma patients receiving chest CT were included. The primary outcome was injury and major clinical injury prevalence and screening performance in patients with combinations of one, two, or three of seven individual NEXUS Chest CT criteria. Across the 11 study sites, rates of chest CT performance ranged from 15.5% to 77.2% (median = 43.6%). We found injuries in 1,493/5,169 patients (28.9%) who had chest CT; 269 patients (5.2%) had major clinical injury (e.g., pneumothorax requiring chest tube). With sensitivity of 73.7 (95% confidence interval [CI] = 68.1 to 78.6) and specificity of 83.9 (95% CI = 83.6 to 84.2) for major clinical injury, abnormal chest-x-ray (CXR) was the single most important screening criterion. When patients had only abnormal CXR, injury and major clinical injury prevalences were 60.7% (95% CI = 52.2% to 68.6%) and 12.9% (95% CI = 8.3% to 19.4%), respectively. Injury and major clinical injury prevalences when any other single criterion alone (other than abnormal CXR) was present were 16.8% (95% CI = 15.2% to 18.6%) and 1.1% (95% CI = 0.1% to 1.8%), respectively.

To develop a risk score based on physical examination and chest X-ray findings to rapidly identify major trauma patients at risk of acute traumatic aortic injury (ATAI). A multicenter retrospective study was conducted with 640 major trauma patients with associated blunt chest trauma classified into ATAI (aortic injury) and NATAI (no aortic injury) groups. The score data set included 76 consecutive ATAI and 304 NATAI patients from a single center, whereas the validation data set included 52 consecutive ATAI and 208 NATAI patients from three independent institutions. Bivariate analysis identified variables potentially influencing the presentation of aortic injury. Confirmed variables by logistic regression were assigned a score according to their corresponding beta coefficient which was rounded to the closest integer value (1-4). Predictors of aortic injury included widened mediastinum, hypotension less than 90 mmHg, long bone fracture, pulmonary contusion, left scapula fracture, hemothorax, and pelvic fracture. Area under receiver operating characteristic curve was 0.96. In the score data set, sensitivity was 93.42 %, specificity 85.85 %, Youden's index 0.79, positive likelihood ratio 6.60, and negative likelihood ratio 0.08. In the validation data set, sensitivity was 92.31 % and specificity 85.1 %. Given the relative infrequency of traumatic aortic injury, which often leads to missed or delayed diagnosis, application of our score has the potential to draw necessary clinical attention to the possibility of aortic injury, thus providing the chance of a prompt specific diagnostic and therapeutic management.

To evaluate the HRCT findings and to correlate the findings with the results of a pulmonary function test (PFT) in patients with reactive airway dysfunction syndrome (RADS). On March 2003, a fire at a boarding house of primary school soccer players caused a multiple casualty disaster. After 8 months, nine boys that presented with chronic cough and dyspnea were treated, and were subjected to follow-up evaluations. Eight patients underwent a chest radiograph, HRCT, and a PET. Two patients with severe symptoms received extended follow-up after 1 year. Two radiologists retrospectively reviewed the chest radiographs and the follow-up HRCT scans. We correlated the HRCT findings with the results of the PET. Six patients with an inhalation injury were diagnosed with RADS. On the chest radiographs, eight patients showed no abnormal findings. On an HRCT scan, four patients showed abnormal findings. The abnormal findings were mosaic air trapping (n = 4), bronchial wall thickening (n = 1), and parenchymal consolidation (n = 1). In all four patients that showed abnormal findings in the HRCT scan, abnormal results of the PET were also seen. The two patients that received extended follow-up showed an improvement of the clinical symptoms, as seen by the PFT, and had a decreased extent and degree of mosaic air trapping, as seen on HRCT. An HRCT scan is an essential modality for the diagnosis and follow-up of patients with RADS. Both a full expiratory and inspiratory HRCT scan must be performed for an accurate diagnosis.

Skin and chest wall doses have been correlated with toxicity in patients treated with breast brachytherapy . This investigation compared the ability to control skin and chest wall doses between patients treated with multicatheter (MC), Contura multilumen balloon (CMLB), and MammoSite (MS) brachytherapy. 43 patients treated with the MC technique, 45 patients treated with the CMLB, and 83 patients treated with the MS were reviewed. The maximum doses delivered to the skin and chest wall were calculated for all patients. The mean maximum skin doses for the MC, CMLB, and MS were 2.3 Gy (67% of prescription dose), 2.8 Gy (82% of prescription dose), and 3.2 Gy per fraction (94% of prescription dose), respectively. Although the skin distances were similar (p = 0.23) for the two balloon techniques, the mean skin dose with the CMLB was significantly lower than with the MS (p = 0.05). The mean maximum rib doses for the MC, CMLB, and MS were 2.3 Gy (67% of prescription dose), 2.8 Gy (82% of prescription dose), and 3.6 Gy per fraction (105% of prescription dose), respectively. Again, the mean rib dose with the CMLB was significantly lower than with the MS (p = 0.002). The MC and CMLB techniques are associated with significantly lower mean skin and rib doses than is the MS. Treatment with the MS was associated with significantly more patients receiving doses to the skin or rib in excess of 125% of the prescription. Treatment with the CMLB may prove to yield less normal tissue toxicity than treatment with the MS. Copyright © 2011 Elsevier Inc. All rights reserved.

Full Text Available Abstract We present the case of a patient who sustained a penetrating injury to the chest caused by an attenuated energy rubber bullet and review the literature on thoracic injuries caused by plastic and rubber "less-lethal" munitions. The patient of this report underwent a right thoracotomy to extract the projectile as well as a wedge resection of the injured lung parenchyma. This case demonstrates that even supposedly safe riot control munition fired at close range, at the torso, can provoke serious injury. Therefore a thorough investigation and close clinical supervision are justified.

Athletic injuries of the lateral abdominal wall: review of anatomy and MR imaging appearance

The lateral abdominal wall is comprised of three muscles, each with a different function and orientation. The transversus abdominus, internal oblique, and external oblique muscles span the abdominal cavity between the iliocostalis lumborum and quadratus lumborum posteriorly and the rectus abdominis anteriorly. The lateral abdominal wall is bound superiorly by the lower ribs and costal cartilages and inferiorly by the iliac crest and inguinal ligament. The lateral abdominal wall may be acutely or chronically injured in a variety of athletic endeavors, with occasional acute injuries in the setting of high-energy trauma such as motor vehicle collisions. Injuries to the lateral abdominal wall may result in lumbar hernia formation, unique for its high incarceration rate, and also Spigelian hernias. This article will review the anatomy, the magnetic resonance (MR) imaging approach, and the features and complications of lateral abdominal wall injuries. (orig.)

Full Text Available Fibromatosis of the breast is a rare benign disease compromising <0.2% of all primary breast tumors. Although the chest wall is a common location, occurrences of implant-associated fibromatosis of the breast are extremely rare; only 33 cases have been reported. We present a case of a 42-year-old female who underwent breast augmentation with silicone breast implants, and 2 years later developed an aggressive implant-associated fibromatosis of the breast and chest wall. On imaging studies, the tumor mimicked breast carcinoma, and despite chemotherapy, the fibromatosis rapidly enlarged and was locally invasive requiring wide surgical excision. Unlike previously reported imaging findings, magnetic resonance imaging revealed an oval circumscribed mass with fringe-like internal architecture. We provide a review of the literature and discuss the imaging features of implant-associated fibromatosis of the breast.

Tube thoracostomy (TT) is required in the treatment of many blunt and penetrating injuries of the chest. In addition to complications from the injuries, TT may contribute to morbidity by introducing microorganisms into the pleural space or by incomplete lung expansion and evacuation of pleural blood. We have attempted to assess the impact of TT following penetrating and blunt thoracic trauma by examining a consecutive series of 216 patients seen at two urban trauma centers with such injuries who required TT over a 30-month period. Ninety-four patients suffered blunt chest trauma; 122 patients were victims of penetrating wounds. Patients with blunt injuries had longer ventilator requirements (12.6 +/- 14 days vs. 3.7 +/- 7.1 days, p = 0.003), longer intensive care stays (12.2 +/- 12.5 days vs. 4.1 +/- 7.5 days, p = 0.001), and longer periods of TT, (6.5 +/- 4.9 days vs. 5.2 +/- 4.5 days, p = 0.018). Empyema occurred in six patients (3%). Residual hemothorax was found in 39 patients (18%), seven of whom required decortication. Recurrent pneumothorax developed in 51 patients (24%) and ten required repeat TT. Complications occurred in 78 patients (36%). Patients with blunt trauma experienced more complications (44%) than those with penetrating wounds (30%) (p = 0.04). However, only seven of 13 patients developing empyema or requiring decortication had blunt trauma. Despite longer requirements for mechanical ventilation, intensive care, and intubation, victims of blunt trauma seemed to have effective drainage of their pleural space by TT without increased risk of infectious complications.

to investigate the effect of standardized interventions in the management of tube thoracostomy patients and to assess the independent effect of each intervention. A chest tube management protocol was assessed in a retrospective cohort study. The tube thoracostomy protocol (TTP) was implemented in August 2012, and consisted of: antimicrobial prophylaxis, chest tube insertion in the operating room (OR), admission post chest tube thoracostomy (CTT) in a hospital floor separate from the emergency department (ED), and daily respiratory therapy (RT) sessions post-CTT. The inclusion criteria were, hemodynamic stability, patients between the ages of 15 and 59 years, and injury severity score (ISS) chest wall, lung, and pleura. During the study period 92 patients were managed according to the standardized protocol. The outcomes of those patients were compared to 99 patients treated before the TTP. Multivariate logistic regression analysis was performed to assess the independent effect of each variable of the protocol on selected outcomes. Demographics, injury severity, and trauma mechanisms were similar among the groups. As expected, protocol compliance increased after the implementation of the TTP. There was a significant reduction (pchest tube days. Respiratory therapy was independently linked to significant reduction (pchest tube insertion was associated with significant (ptrauma patients.

Traumas are the third most common cause of death worldwide, after cardiovascular diseases and neoplasms, and the main cause of death of patients under 40 years of age. Contemporary image diagnosis of chest trauma uses chest X-ray (CXR), multidetector computed tomography (MDCT), transthoracic and transoesophageal ultrasound (USG), X-ray angiography and magnetic resonance. The aim of the present study was to evaluate MDCT results in the examination of posttraumatic chest injuries and to compare the results of CXR and MDCT in chosen chest traumatic injuries. The sixty patients with chest trauma included in the study were diagnosed at the Department of Radiology of the Institute of Tuberculosis and Lung Diseases between May 2004 and October 2007. MDCT was performed in all patients. Two groups with different types of injury (blunt or penetrating chest trauma) were distinguished. The analysis of injuries in both groups was conducted depending on the mechanism of trauma. The detection of 20 selected injuries at CXR and MDCT was compared. Moreover, the compatibility of MDCT with the results of intraoperative assessment and bronchoscopy was analysed. The influence of MDCT on the treatment modality was also assessed. History of blunt chest trauma was found in 51 patients (group 1) and of penetrating trauma in 9 patients (group 2). The most frequent injuries among group 1 were lung contusion and rib fractures, and among group 2 it was pericardial hematoma. Compared to MDCT, the sensitivity and specificity of CXR were 66.7 and 58%, respectively. Change of treatment modality was observed after MDCT in 83% of patients. The sensitivity and specificity of MDCT in diagnosing tracheobronchial injury, compared to bronchoscopy, were 72.7% and 100%, respectively. Compatibility of MDCT results and intraoperative assessment was observed in 43% of patients, and the main reason for discrepancy was underdiagnosis of diaphragm injury in MDCT. MDCT was a valuable diagnostic method in

Chest wall injury after stereotactic radiotherapy (SRT) for primary lung cancer has recently been reported. However, its detailed imaging findings are not clarified. So this study aimed to fully characterize the findings on computed tomography (CT), appearance time and frequency of chest wall injury after stereotactic radiotherapy (SRT) for primary lung cancer A total of 177 patients who had undergone SRT were prospectively evaluated for periodical follow-up thin-section CT with special attention to chest wall injury. The time at which CT findings of chest wall injury appeared was assessed. Related clinical symptoms were also evaluated. Rib fracture was identified on follow-up CT in 41 patients (23.2%). Rib fractures appeared at a mean of 21.2 months after the completion of SRT (range, 4 -58 months). Chest wall edema, thinning of the cortex and osteosclerosis were findings frequently associated with, and tending to precede rib fractures. No patients with rib fracture showed tumors > 16 mm from the adjacent chest wall. Chest wall pain was seen in 18 of 177 patients (10.2%), of whom 14 patients developed rib fracture. No patients complained of Grade 3 or more symptoms. Rib fracture is frequently seen after SRT for lung cancer on CT, and is often associated with chest wall edema, thinning of the cortex and osteosclerosis. However, related chest wall pain is less frequent and is generally mild if present

Introduction: Recent studies have renewed an old controversy about the efficacy of adjuvant radiotherapy following mastectomy for breast cancer. Radiotherapy is usually recommended for advanced disease, but whether or not to use it in pT1-T2 pN0 situations is still being debated. This study was designed to clarify whether or not routine radiotherapy of the chest wall following mastectomy reduces the risk of local recurrence and if it influences the overall survival rate. Methods: Retrospective analysis of patients treated with mastectomy for pT1-T2 pN0 tumors and no systemic treatment. Patients treated with radiotherapy of the chest wall following mastectomy (Group A) are compared with those treated with mastectomy alone (Group B). Results: A total of 918 patients underwent mastectomy. Patients who received adjuvant radiotherapy after mastectomy (n = 114) had a significantly lower risk for local recurrence. Ten years after the primary diagnosis, 98.1% of the patients with radiotherapy were disease free compared to 86.4% of the patients without radiotherapy. The average time interval from primary diagnosis until local recurrence was 8.9 years in Group A and 2.8 years in Group B. The Cox regression analysis including radiotherapy, tumor size and tumor grading found the highest risk for local recurrence for patients without radiotherapy (p < 0.0004). In terms of overall survival however, the Kaplan-Meier analysis showed no difference between the two groups (p = 0.8787) and the Cox regression analysis failed to show any impact on overall survival. Conclusion: With observation spanning over 35 years, this study shows that adjuvant radiotherapy of the chest wall following mastectomy reduces the risk for local recurrence in node-negative patients with pT1-T2 tumors but has no impact on the overall survival rate

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.)

Helical tomotherapy (HT has the ability to deliver continuous craniocaudal irradiation that suppresses junction problems and provides good conformity of dose distribution. A 47-year-old female with stage IV bilateral breast cancer with chest wall and pectoralis major muscle invasion, lymphadenopathy, bilateral pleural effusion, and multiple bone metastases received chemotherapy and target therapy beginning in January 2014; 4 months after the initiation of chemotherapy, computed tomography revealed progression of chest and abdominal wall invasion. A total dose of 70.2 Gy was delivered to both breasts, the chest wall, the abdominal wall, and the bilateral supraclavicular nodal areas in 39 fractions via HT. The total planning target volume was 4,533.29 cm3. The percent of lung volume receiving at least 20 Gy (V20 was 28%, 22%, and 25% for the right lung, left lung, and whole lung, respectively. The mean dose to the heart was 8.6 Gy. Follow-up computed tomography revealed complete response after the RT course. Grade 1 dysphagia, weight loss, grade 2 neutropenia, and grade 3 dermatitis were noted during the RT course. Pain score decreased from 6 to 1. No cardiac, pulmonary, liver, or intestinal toxicity

Penetrating injuries to the chest present a frequent and challenging problem, but the majority of these injuries can be managed non-\\operatively. The aim of this study was to describe the incidence of penetrating chest trauma and the ultimate techniques used for operative management, as well as the diagnosis, complications, morbidity and mortality. A retrospective 9-year review of patients who underwent an operative procedure following penetrating chest trauma was performed. The mechanism of injury, gender, age, physiological and outcome parameters, including injury severity score (ISS), chest abbreviated injury scale (AIS) score, lung injury scale score, concomitant injuries, time from admission to operating room, transfusion requirement, indications for thoracotomy, intra-operative findings, operative procedures, length of hospital stay (LOS) and rate of mortality were recorded. A total of 1123 patients who were admitted with penetrating thoracic trauma were investigated. Of these, 158 patients (93 stabbings, 65 gunshots) underwent a thoracotomy within 24 h after the penetrating trauma. There were 146 (92.4%) male and 12 (7.6%) female patients, and their mean age was 25.72 9.33 (range, 15–54) years. The mean LOS was 10.65 8.30 (range, 5–65) days. Patients admitted after a gunshot had a significantly longer LOS than those admitted with a stab wound (gunshot, 13.53 9.92 days; stab wound, 8.76 6.42 days, p chest AIS score (p chest requiring a thoracotomy are uncommon, and lung-sparing techniques have become the most frequently used procedures for lung injuries. The presence of associated abdominal injuries increased the mortality five-fold. Factors that affected mortality were ISS, chest AIS score, SBP, ongoing chest output, blood transfusion volume, diaphragmatic injury and associated abdominal injury.

lung injuries was obtained largely with intracorporeal knot tying. The duration of the procedures ranged from 40 to 90 minutes. No morbidity nor mortality was encountered in patients undergoing OVT. Postoperative pain was minimized by using OVT placement of catheters in the chest wall soft tissue with local administration of 2% Trimecain. Patients were able to stand in 10 to 12 hours and to walk by the end of the first postoperative day. All patients who underwent OVT were evacuated without drains by the third or fourth postoperative day, all tolerating sitting and standing positions. We conclude that early OVT in the military field hospital for continued bleeding, clotted hemothorax, and continued major air leakage has several advantages in military patients with PFAWT: early definition and management of organ injury; identification and control of bleeding in most instances; earlier and more accurate assessment for thoracotomy; vigorous lavage and removal of projectiles such as bone fragments and evacuation of clotted hemothorax; early debridement with suture closure of the thoracic wall canal; and minimal postoperative pain with dramatically reduced suppurative sequelae and bronchopleural fistulae.

Trauma is the leading cause of mortality in children over one year of age in industrialized countries. In this retrospective study we reviewed all chest trauma in pediatric patients admitted to Mansoura University Emergency Hospital from January 1997 to January 2007. Our hospital received 472 patients under the age of 18. Male patients were 374 with a mean age of 9.2±4.9 years. Causes were penetrating trauma (2.1%) and blunt trauma (97.9%). The trauma was pedestrian injuries (38.3%), motor vehicle (28.1%), motorcycle crash (19.9%), falling from height (6.7%), animal trauma (2.9%), and sports injury (1.2%). Type of injury was pulmonary contusions (27.1%) and lacerations (6.9%), rib fractures (23.9%), flail chest (2.5%), hemothorax (18%), hemopneumothorax (11.8%), pneumothorax (23.7%), surgical emphysema (6.1%), tracheobronchial injury (5.3%), and diaphragm injury (2.1%). Associated lesions were head injuries (38.9%), bone fractures (33.5%), and abdominal injuries (16.7%). Management was conservative (29.9%), tube thoracostomy (58.1%), and thoracotomy (12.1%). Mortality rate was 7.2% and multiple trauma was the main cause of death (82.3%) (Ptrauma is the most common cause of pediatric chest trauma and often due to pedestrian injuries. Rib fractures and pulmonary contusions are the most frequent injuries. Delay in diagnosis and multiple trauma are associated with high incidence of mortality. Copyright © 2011 SEPAR.

Full Text Available Abstract Background Chest wall injury after stereotactic radiotherapy (SRT for primary lung cancer has recently been reported. However, its detailed imaging findings are not clarified. So this study aimed to fully characterize the findings on computed tomography (CT, appearance time and frequency of chest wall injury after stereotactic radiotherapy (SRT for primary lung cancer Materials and methods A total of 177 patients who had undergone SRT were prospectively evaluated for periodical follow-up thin-section CT with special attention to chest wall injury. The time at which CT findings of chest wall injury appeared was assessed. Related clinical symptoms were also evaluated. Results Rib fracture was identified on follow-up CT in 41 patients (23.2%. Rib fractures appeared at a mean of 21.2 months after the completion of SRT (range, 4 -58 months. Chest wall edema, thinning of the cortex and osteosclerosis were findings frequently associated with, and tending to precede rib fractures. No patients with rib fracture showed tumors > 16 mm from the adjacent chest wall. Chest wall pain was seen in 18 of 177 patients (10.2%, of whom 14 patients developed rib fracture. No patients complained of Grade 3 or more symptoms. Conclusion Rib fracture is frequently seen after SRT for lung cancer on CT, and is often associated with chest wall edema, thinning of the cortex and osteosclerosis. However, related chest wall pain is less frequent and is generally mild if present.

Low triiodothyronine (T3) levels and subclinical myocardial injury may be associated with adverse cardiac and cerebrovascular (CCV) events in individuals without clinically apparent coronary heart disease (CHD). The aim of this study was to determine the associations of a low T3 level and subclinical myocardial injury with the development of adverse CCV events in individuals without clinically apparent CHD. T3 and high-sensitivity cardiac troponin T (hs-cTnT) levels were analyzed in 250 patients with chest pain free of CHD and heart failure. The primary end point was the composite of sudden cardiac death, ischemic stroke, newly developed atrial fibrillation, pericardial effusion and thrombosis. Throughout a mean follow-up of 15.6 months, the primary end point happened in 17 patients (6.8%). Kaplan-Meier analysis disclosed a notably higher overall occurrence rate in patients with hs-cTnT levels ≥0.014 ng/mL and in patients with T3 <60 ng/dL. An exaggerated hazard was observed in patients with combined high hs-cTnT and low T3 levels. After adjustment, the hazard ratio for overall events in patients with high hs-cTnT/low T3 versus normal hs-cTnT/T3 was 11.72 (95% confidence interval, 2.83-48.57; P = 0.001). In patients with chest pain without clinically obvious CHD, high hs-cTnT combined with low T3 was associated with adverse cardiac/CCV events and was an independent predictor of overall events even after adjustment. These data suggest the importance of systemic factors, such as low T3 syndrome, in the development of adverse cardiac/CCV events beyond advancing clinical atherosclerotic coronary disease in patients with chest pain.

Right sided tears or rupture are the most common injury to the heart after blunt chest trauma. The majority of these injuries are to the thin walled atrium. Reports of localized right atrial appendage rupture are rare. The classical features of Beck's triad are unreliable in the trauma bay. With the advent of EFAST (Focused assessment with sonography for trauma extended to thorax), Beck's triad should be considered but not used as the primary clinical tool for diagnosis of cardiac tamponade [1]. EFAST aids in rapid diagnosis and definitive care [3]. Our patient was a 17 year old male who presented with hypotension after a rollover motor vehicle accident. He presented with a grossly negative physical exam and positive EFAST for pericardial effusion with tamponade physiology. We performed an emergency pericardiocentesis and expedited transportation for operative exploration. A Right atrial appendage injury was identified and repaired and patient recovered uneventfully. EFAST examination aids in rapid diagnosis of cardiac tamponade in the trauma setting. Pericardiocentesis facilitates temporizing the hemodynamics in preparation for operative exploration.

Thoracic trauma is the third most common cause of death after abdominal injury and head trauma in polytrauma patients. The purpose of this study was to investigate epidemiological data, treatment and outcome of polytrauma patients with blunt chest trauma in order to help improve management, prevent complications and decrease polytrauma patients' mortality. In this retrospective study we included all polytrauma patients with blunt chest trauma admitted to our tertiary care center emergency department for a 2-year period, from June 2012 until May 2014. Data collection included details of treatment and outcome. Patients with chest trauma and Injury Severity Score (ISS) ≥18 and Abbreviated Injury Scale (AIS) >2 in more than one body region were included. A total of 110 polytrauma patients with blunt chest injury were evaluated. 82 of them were males and median age was 48.5 years. Car accidents, falls from a height and motorbike accidents were the most common causes (>75%) for blunt chest trauma. Rib fractures, pneumothorax and pulmonary contusion were the most common chest injuries. Most patients (64.5%) sustained a serious chest injury (AIS thorax 3), 19.1% a severe chest injury (AIS thorax 4) and 15.5% a moderate chest injury (AIS thorax 2). 90% of patients with blunt chest trauma were treated conservatively. Chest tube insertion was indicated in 54.5% of patients. The need for chest tube was significantly higher among the AIS thorax 4 group in comparison to the AIS groups 3 and 2 (p < 0.001). Also, admission to the ICU was directly related to the severity of the AIS thorax (p < 0.001). The severity of chest trauma did not correlate with ICU length of stay, intubation days, complications or mortality. Although 84.5% of patients suffered from serious or even severe chest injury, neither in the conservative nor in the surgically treated group a significant impact of injury severity on ICU stay, intubation days, complications or mortality was observed.

We assessed the occurrence and aetiology of chest pain in primary care practice. These features differ between primary and emergency care settings, where most previous studies have been performed. 59 GPs in western Switzerland recorded all consecutive cases presenting with chest pain. Clinical characteristics, laboratory tests and other investigations as well as the diagnoses remaining after 12 months of follow-up were systematically registered. Among 24,620 patients examined during a total duration of 300 weeks of observation, 672 (2.7%) presented with chest pain (52% female, mean age 55 +/- 19(SD)). Most cases, 442 (1.8%), presented new symptoms and in 356 (1.4%) it was the reason for consulting. Over 40 ailments were diagnosed: musculoskeletal chest pain (including chest wall syndrome) (49%), cardiovascular (16%), psychogenic (11%), respiratory (10%), digestive (8%), miscellaneous (2%) and without diagnosis (3%). The three most prevalent diseases were: chest wall syndrome (43%), coronary artery disease (12%) and anxiety (7%). Unstable angina (6), myocardial infarction (4) and pulmonary embolism (2) were uncommon (1.8%). Potentially serious conditions including cardiac, respiratory and neoplasic diseases accounted for 20% of cases. A large number of laboratory tests (42%), referral to a specialist (16%) or hospitalisation (5%) were performed. Twentyfive patients died during follow-up, of which twelve were for a reason directly associated with thoracic pain [cancer (7) and cardiac causes (5)]. Thoracic pain was present in 2.7% of primary care consultations. Chest wall syndrome pain was the main aetiology. Cardio - vascular emergencies were uncommon. However chest pain deserves full consideration because of the occurrence of potentially serious conditions.

We report the case of a 76-year-old woman who had undergone breast-conserving surgery for left breast cancer, followed by irradiation at a total dose of 66 Gy in 2005. When 5 years 1 month had elapsed after the operation, redness of the left chest wall was observed. A biopsy was performed and the histopathological diagnosis was angiosarcoma. Extended resection of the full thickness of the skin was performed. Adequate resection left a massive defect 15 x 18 cm in size. The divided latissimus dorsi flap was designed, and the oval-shaped skin defect was closed with the skin island of this flap. Post-irradiation sarcoma involving the vessels is a rare entity and occurs in 0.07-0.48% of all cases after radiation therapy. It metastasizes to the distant organs in an early stage and has a poor prognosis. No standard therapy for the disease has been established. Early detection and extended resection are considered to contribute to improvement of the prognosis. The divided latissimus dorsi flap is very useful for reconstructing a wide chest wall defect without the need to wide skin graft the donor site. (author)

Contemporary management of flail chest.

Vana, P Geoff; Neubauer, Daniel C; Luchette, Fred A

2014-06-01

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.

Lung and chest wall impedances in the dog in normal range of breathing: effects of pulmonary edema.

Barnas, G M; Stamenović, D; Lutchen, K R

We evaluated the effect of pulmonary edema on the frequency (f) and tidal volume (VT) dependences of respiratory system mechanical properties in the normal ranges of breathing. We measured resistance and elastance of the lungs (RL and EL) and chest wall of four anesthetized-paralyzed dogs during sinusoidal volume oscillations at the trachea (50-300 ml, 0.2-2 Hz), delivered at a constant mean airway pressure. Measurements were made before and after severe pulmonary edema was produced by injection of 0.06 ml/kg oleic acid into the right atrium. Chest wall properties were not changed by the injection. Before oleic acid, EL increased slightly with increasing f in each dog but was independent of VT. RL decreased slightly and was independent of VT from 0.2 to 0.4 Hz, but above 0.4 Hz it tended to increase with increasing flow, presumably due to the airway contribution. After oleic acid injection, EL and RL increased greatly. Large negative dependences of EL on VT and of RL on f were also evident, so that EL and RL after oleic acid changed two- and fivefold, respectively, within the ranges of f and VT studied. We conclude that severe pulmonary edema changes lung properties so as to make behavior VT dependent (i.e., nonlinear) and very frequency dependent in the normal range of breathing.

Rib fractures are common after chest wall trauma. For patients with flail chest, surgical stabilization is a promising technique for reducing morbidity. Anatomical difficulties often lead to an inability to completely repair the flail chest; thus, the result is partial flail chest stabilization (PFS). We hypothesized that patients with PFS have outcomes similar to those undergoing complete flail chest stabilization (CFS). A prospectively collected database of all patients who underwent rib fracture stabilization procedures from August 2009 until February 2013 was reviewed. Abstracted data included procedural and complication data, extent of stabilization, and pulmonary function test results. Of 43 patients who underwent operative stabilization of flail chest, 23 (53%) had CFS and 20 (47%) underwent PFS. Anterior location of the fracture was the most common reason for PFS (45%). Age, sex, operative time, pneumonia, intensive care unit and hospital length of stay, and narcotic use were the same in both groups. Total lung capacity was significantly improved in the CFS group at 3 months. No chest wall deformity was appreciated on follow-up, and no patients underwent additional stabilization procedures following PFS. Despite advances in surgical technique, not all fractures are amenable to repair. There was no difference in chest wall deformity, narcotic use, or clinically significant impairment in pulmonary function tests among patients who underwent PFS compared with CFS. Our data suggest that PFS is an acceptable strategy and that extending or creating additional incisions for CFS is unnecessary.

Ultrasound (US) of chest, even with inherent limitations of the US beam and air, has been useful in many pediatric chest conditions. It has extended its role and is now widely used by many subspecialists in medicine. This review article will cover techniques, indications, and applications of chest US in neonates, infants and children, including also different common as well as some rare and modern aspects and applications, such as pleural effusion, pneumothorax, pulmonary lesions, mediastinum, diaphragm, and chest wall. Other related imaging modalities are also briefly discussed.

Congenital sternal cleft is a rare chest wall malformation. Because of the flexibility of the chest in infants, surgical repair should be performed by primary closure in the neonatal period. In adolescents and adults, different techniques have been suggested to overcome the lack of sternal bone tissue. We describe a very rare case of an 18-year-old woman with a complete bifid sternum associated with pectus excavatum for whom a satisfactory cosmetic and functional result was obtained by adequate surgical planning, which entailed a combination of two standardized surgical techniques.

CT evaluation of pulmonary parenchymal injury due to blunt chest trauma and its clinical significance

International Nuclear Information System (INIS)

Niimi, Hiroshi

1990-01-01

The CT findings of pulmonary parenchymal injury due to blunt chest trauma in 73 patients and their clinical significance were analyzed. CT was obtained within 6 hours after trauma. Findings were analyzed according to the number of injured segments and severity which was classified into three grades. A correlation was also made with arterial blood PaO 2 and thoracic complications. Pulmonary parenchymal injury was identified in multisegmental portions bilaterally in most cases. It was most frequently observed in the posterior portion of the lung such as segment 6. More than 50% of lesions were classified as Grade 1. Pulmonary laceration, defined as patchy density with the cavitary lesion (Grade 3), was noted in 9.2%. There was a good correlation between extent of pulmonary injury and degree of hypoxia. The correlation of pneumothorax was also found with extensive lesion and frequency of Grade 3 lesion. Cases with pulmonary laceration tend to have extensive injury, and be related to the degree of hypoxia. In conclusion, CT evaluation of pulmonary parenchymal injury is valuable not only for morphological evaluation but also for estimation of hypoxia. (author)

Ventricular septal necrosis after blunt chest trauma

Alireza Ahmadi

2012-07-01

Full Text Available Ventricular Septal Defect (VSD after blunt chest trauma is a very rare traumatic affection.We report here a case of blunt chest injury-related VSD and pseudoaneurysm.A 30-year old male truck driver was referred from a trauma center to our hospital seven days after a blunt chest trauma and rib fracture. The patient had severe pulmonary edemaand echocardiography showed large VSD. Several mechanisms are involved in the pathogenesis of this affection including an acute compression of the heart muscle between the sternum and the spine, leading to excessive changes in the intrathoracic and most likely theintracardiac pressure after blunt chest injury. Traumatical patients with the same symptoms may be at risk of sudden death. Therefore, a high grade of suspicion is mandatory even without solid evidence of myocardial damage on the initial evaluation. In continue somehidden angles of this case was discussed. Given the prognostic implications of traumatic VSD with associated pseudoaneurysm, its detection has critical value for preventing its clinicalsequelae.

Treatment of necrotic infection on the anterior chest wall secondary to mastectomy and postoperative radiotherapy by the application of omentum and mesh skin grafting. Report of a case

We report herein the case of a patient who initially underwent right radical mastectomy for breast carcinoma in 1988, followed by left breast-conserving surgery in 1997. On both occasions she was given postoperative radiation therapy of 50 Gy. Repeated dressings and the administration of antibiotics failed to heal ulcerative infected lesions that had formed on the anterior chest wall in early 1998. In 1999, the sternum and surrounding tissue were debrided and the anterior chest wall was reconstructed by omentum transposition and mesh skin grafting. The patient is currently well and alive without any evidence of recurrence of either infection or breast cancer. (author)

Al-Sadek, Tabet A.; Niklev, Desislav; Al-Sadek, Ahmed; Al-Sadek, Lina

2016-01-01

AIM: The aim of this retrospective study was to report the scapular fractures in patients with blunt chest trauma and to present the type and the frequency of associated thoracic injuries. MATERIAL AND METHODS: Nine patients with fractures of the scapula were included in the study. The mechanisms of the injury, the type of scapular fractures and associated thoracic injuries were analysed. RESULTS: Scapular fractures were caused by high-energy blunt chest trauma. The body of the scapula was fractured in all scapular fractures. In all cases, scapular fractures were associated with other thoracic injuries (average 3.25/per case). Rib fractures were present in eight patients, fractured clavicula - in four cases, the affection of pleural cavity - in eight of the patients and pulmonary contusion in all nine cases. Eight patients were discharged from the hospital up to the 15th day. One patient had died on the 3rd day because of postconcussional lung oedema. CONCLUSIONS: The study confirms the role of scapular fractures as a marker for the severity of the chest trauma (based on the number of associated thoracic injuries), but doesn’t present scapular fractures as an indicator for high mortality in blunt chest trauma patients.

2016-01-01

Delivering radiotherapy to the postmastectomy chest wall can be achieved using matched electron fields. Surgical defects of the chest wall change the dose distribution of electrons. In this study, the improvement of dose homogeneity using simple, nonconformal techniques of thermoplastic bolus application on a defect is evaluated. The proposed phantom design improves the capability of film dosimetry for obtaining dose profiles of a patient's anatomical condition. A modeled electron field of a patient with a postmastectomy inward surgical defect was planned. High energy electrons were delivered to the phantom in various settings, including no bolus, a bolus that filled the inward defect (PB0), a uniform thickness bolus of 5 mm (PB1), and two 5 mm boluses (PB2). A reduction of mean doses at the base of the defect was observed by any bolus application. PB0 increased the dose at central parts of the defect, reduced hot areas at the base of steep edges, and reduced dose to the lung and heart. Thermoplastic boluses that compensate a defect (PB0) increased the homogeneity of dose in a fixed depth from the surface; adversely, PB2 increased the dose heterogeneity. This study shows that it is practical to investigate dose homogeneity profiles inside a target volume for various techniques of electron therapy. PMID:27051169

Coronary artery bypass grafting and concomitant excision of chest wall chondrosarcoma

2009-02-01

Full Text Available Abstract Coexistence of coronary artery disease and cancer with both requiring surgical treatment at the same time is rare. A 52 year male undergoing elective coronary artery bypass grafting was incidentally discovered to have a large soft tissue mass of variable consistency with cartilaginous elements arising from the right costal margin and adjoining ribs by a broad attachment and protruding into right pleural cavity. Frozen section suggested it to be either a chondrosarcoma or a teratoma. A wide excision of the mass with the adjoining muscle and periosteum along with quadruple coronary artery bypass grafting was done. This report is unusual on account of a being the first reported case in world literature of concomitant excision of chondrosarcoma and coronary artery bypass grafting and b the conservative management of the incidentally discovered chondrosarcoma by wide excision rather than chest wall resection with no local recurrence to date. Pathology of chondrosarcoma, in particular, and various management strategies when coronary artery disease and cancer coexist, in general, is discussed.

The determine the chest CT findings in breast cancer patients who have undergone postoperative irradiation. The chest CT findings in 36 female patients who underwent breast surgery and radiotherapy between May 1996 and March 2000 were rerospectively analysed. Prior to radiotheraphy, baseline chest CT depicted normal parenchyma in all cases. In 11 patients, the ipsilateral breast and chest wall were irradiated using opposed tangential fields, while 25 were treated by the four fields method (opposed tangential fields plus anterior and posterior supraclavicular/high axillary fields), with a total dose of 5040-5400 cGy for 5-9 weeks. CT after radiotherapy demonstrated reticular opacity (n=24), perpendicular linear opacity (n=15), traction bronchiectasis (n=7), consolidation (n=6), ground glass attenuation (n=3), pathologic rib fractures (n=3) pleural effusion (n=2), and pleural thickening (n=1), while in five patients no abnormality was observed. in addition, in the anterolateral lung area of 23 (64%) of 36 patients who underwent tangential beam irradiation, CT demonstrated peripheral opacities. When supraclavicular and axillary portals were used, radiation-induced lung changes mostly occurred at the apex of the lung (n=24). Chest radiographs were abnormal in 26 patients and normal in ten; in five of these ten, CT demonstrated reticular opacity. Depending on the irradiation CT findings of radiation-induced lung injury in breast cancer include areas of increased opacity with or without fibrosis, in apical and/or anterior subpleural regions. CT may help differentiate radiation-induced parenchymal change from superimposed or combined lung disease.

Blunt chest injury with multiple rib fractures can result in such complications as pneumonia, atelectasis, bronchiectasis, empyema thoracis, acute respiratory distress syndrome, and prolonged Intensive Care Unit and hospital stay, with its concomitant mortality. These may be prevented or reduced by good analgesic therapy which is the subject of this study. This was a prospective study of effects of analgesia on changes in pulmonary functions of patients with traumatic multiple rib fractures resulting from blunt chest injury. There were 64 adult patients who were studied with multiple rib fractures caused by blunt chest trauma. Of these patients, 54 (84.4%) were male and 10 (15.6%) were female. Motorcycle (popularly known as "okada") and tricycle (popularly known as keke napep) accidents significantly accounted for the majority of the multiple rib fractures, that is, in 50 (78.1%) of the patients. Before analgesic administration, no patient had a normal respiratory rate, but at 1 h following the administration of analgesic, 21 (32.8%) of patients recorded normal respiratory rates and there was a significant reduction in the number (10.9% vs. 39.1%) of patients with respiratory rates> 30 breaths/min. Before commencement of analgesic, no patient recorded up to 99% of oxygen saturation (SpO2) as measured by pulse oximeter, while 43.8% recorded SpO2of 96%. This improved after 1 h of administration of analgesics to SpO2of 100% in 18.8% of patients and 99% in 31.3% of patients and none recording SpO2of 100% of predicted while only 9 (14.1%) patients were able to achieve a PEFR value in the range of 91%-100% of predicted value. One hour after analgesia, a total of 6 (9.4%) patients were able to achieve PEFR values> 100% predicted, while 35 (54.7%) patients achieved PEFR values in the range of 91%-100% predicted. Adequate analgesia is capable of reversing the negative effects of chest pain of traumatic multiple rib fractures on pulmonary function parameters through

In chest trauma, a routine chest film, preferably in the lateral as well as the frontal projection, is the basic part of the work-up. Occasionally valuable additional methods are fluoroscopy, tomography, bronchography, contrast studies of the GI Tract and angiography and angiocardiography. In 679 chest trauma patients, traffic accidents and falls were the main reason for the trauma. There were 248 fractures; then - in order of frequency - hemopneumothorax (76), lung contusion (58), subcutaneous emphysema (33) cardiac (16) and vascular trauma (12) and damage to other organs. While 20-30% mistakes are made in diagnosing rib fractures in acute trauma, there is high accuracy in the diagnosis of the other injuries. Many cases are shown to demonstrate the value of diagnostic radiology. (orig.) [de

Anteroposterior chest radiograph vs. chest CT scan in early detection of pneumothorax in trauma patients

Directory of Open Access Journals (Sweden)

2011-09-01

Full Text Available Abstract Pneumothorax is a common complication following blunt chest wall trauma. In these patients, because of the restrictions regarding immobilization of the cervical spine, Anteroposterior (AP chest radiograph is usually the most feasible initial study which is not as sensitive as the erect chest X-ray or CT chest for detection of a pneumothorax. We will present 3 case reports which serve for better understanding of the entity of occult pneumothorax. The first case is an example of a true occult pneumothorax where an initial AP chest X-ray revealed no evidence of pneumothorax and a CT chest immediately performed revealed evidence of pneumothorax. The second case represents an example of a missed rather than a truly occult pneumothorax where the initial chest radiograph revealed clues suggesting the presence of pneumothorax which were missed by the reading radiologist. The third case emphasizes the fact that "occult pneumothorax is predictable". The presence of subcutaneous emphesema and pulmonary contusion should call for further imaging with CT chest to rule out pneumothorax. Thoracic CT scan is therefore the "gold standard" for early detection of a pneumothorax in trauma patients. This report aims to sensitize readers to the entity of occult pneumothorax and create awareness among intensivists and ER physicians regarding the proper diagnosis and management.

Recently, three patients with hemopericardium after severe chest trauma were successfully managed nonoperatively at our institution. This prompted the question whether these were rare or common events. Therefore, we reviewed our experience with similar injuries to test the hypothesis that trauma-induced hemopericardium mandates sternotomy. Records were retrospectively reviewed for all patients at a Level I trauma center (December 1996 to November 2011) who sustained chest trauma with pericardial window (PCW, n = 377) and/or median sternotomy (n = 110). Fifty-five (15%) patients with positive PCW proceeded to sternotomy. Penetrating injury was the dominant mechanism (n = 49, 89%). Nineteen (35%) were hypotensive on arrival or during initial resuscitation. Most received surgeon-performed focused cardiac ultrasound examinations (n = 43, 78%) with positive results (n = 25, 58%). Ventricular injuries were most common, with equivalent numbers occurring on the right (n = 16, 29%) and left (n = 15, 27%). Six (11%) with positive PCW had isolated pericardial lacerations, but 21 (38%) had no repairable cardiac or great vessel injury. Those with therapeutic versus nontherapeutic sternotomies were similar with respect to age, mechanisms of injury, injury severity scores, presenting laboratory values, resuscitation fluids, and vital signs. Multiple logistic regression revealed that penetrating trauma (odds ratio: 13.3) and hemodynamic instability (odds ratio: 7.8) were independent predictors of therapeutic sternotomy. Hemopericardium per se may be overly sensitive for diagnosing cardiac or great vessel injuries after chest trauma. Some stable blunt or penetrating trauma patients without continuing intrapericardial bleeding had nontherapeutic sternotomies, suggesting that this intervention could be avoided in selected cases.

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.)

New developments in ultrasonic imaging of the chest and other body organs

International Nuclear Information System (INIS)

Campbell, G.W.; Anderson, A.L.

1978-01-01

The ultrasonic imaging system described herein was developed to measure chest-wall thickness and the percentage of fat in the chest and around other body organs. The system uses pulse-echo techniques to transmit and detect sound waves reflected from the interfaces of body organs and adjacent tissue. A computer draws these interfaces on color scans, and a code is used to exponentially average data from several points on each scan to find the average thicknesses of the chest wall and fat layers. These average thicknesses are then used to adjust x-ray calibration factors for plutonium lung counters. The correction factor for three subjects measured for fat content ranging from 12.6 to 22.2% was 18 to 41%. The ultrasonic system also defines the shape and position of the kidneys and liver so we are able to more accurately place detectors on the body during in-vivo radiation measurements. We have also developed a technique for displaying the interfaces from a series of ultrasonic chest scans to produce a topographical map that enables us to better understand the shape and contour of the lung and chest-wall interface

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.)

Thoracic trauma represents 5% of all battlefield injuries. Communicating pneumothoraces resulting in tension physiology remain an important etiology of prehospital mortality. In addressing penetrating chest trauma, current Tactical Combat Casualty Care (TCCC) guidelines advocate the immediate placement of a vented chest seal device. Although the Committee on TCCC (CoTCCC) has approved numerous chest seal devices for battlefield use, few data exist regarding their use in a combat zone setting. To evaluate adherence to TCCC guidelines for chest seal placement among personnel deployed to Afghanistan. We obtained data from the Prehospital Trauma Registry (PHTR). Joint Trauma System personnel linked patients to the Department of Defense Trauma Registry, when available, for outcome data upon reaching a fixed facility. In the PHTR, we identified 62 patients with documented gunshot wound (GSW) or puncture wound trauma to the chest. The majority (74.2%; n = 46) of these were due to GSW, with the remainder either explosive-based puncture wounds (22.6%; n = 14) or a combination of GSW and explosive (3.2%; n = 2). Of the 62 casualties with documented GSW or puncture wounds, 46 (74.2%) underwent chest seal placement. Higher proportions of patients with medical officers in their chain of care underwent chest seal placement than those that did not (63.0% versus 37.0%). The majority of chest seals placed were not vented. Of patients with a GSW or puncture wound to the chest, 74.2% underwent chest seal placement. Most of the chest seals placed were not vented in accordance with guidelines, despite the guideline update midway through the study period. These data suggest the need to improve predeployment training on TCCC guidelines and matching of the Army logistical supply chain to the devices recommended by the CoTCCC. 2017.

This review aims to answer the most common questions in routine surgical practice during the first 48 h of blunt chest trauma (BCT) management. Two authors identified relevant manuscripts published since January 1994 to January 2014. Using preferred reporting items for systematic reviews and meta-analyses statement, they focused on the surgical management of BCT, excluded both child and vascular injuries and selected 80 studies. Tension pneumothorax should be promptly diagnosed and treated by needle decompression closely followed with chest tube insertion (Grade D). All traumatic pneumothoraces are considered for chest tube insertion. However, observation is possible for selected patients with small unilateral pneumothoraces without respiratory disease or need for positive pressure ventilation (Grade C). Symptomatic traumatic haemothoraces or haemothoraces >500 ml should be treated by chest tube insertion (Grade D). Occult pneumothoraces and occult haemothoraces are managed by observation with daily chest X-rays (Grades B and C). Periprocedural antibiotics are used to prevent chest-tube-related infectious complications (Grade B). No sign of life at the initial assessment and cardiopulmonary resuscitation duration >10 min are considered as contraindications of Emergency Department Thoracotomy (Grade C). Damage Control Thoracotomy is performed for either massive air leakage or refractive shock or ongoing bleeding enhanced by chest tube output >1500 ml initially or >200 ml/h for 3 h (Grade D). In the case of haemodynamically stable patients, early video-assisted thoracic surgery is performed for retained haemothoraces (Grade B). Fixation of flail chest can be considered if mechanical ventilation for 48 h is probably required (Grade B). Fixation of sternal fractures is performed for displaced fractures with overlap or comminution, intractable pain or respiratory insufficiency (Grade D). Lung herniation, traumatic diaphragmatic rupture and pericardial rupture are life

Gastric rupture after blunt abdominal trauma is a rare injury with few reports in the literature. The purpose of this study was to review our experience with blunt gastric injuries and compare outcomes with small bowel or colon injuries. All patients with hollow viscus perforations after blunt abdominal trauma from 1992 to 2005 at our level I trauma center were reviewed. Of 35,033 blunt trauma admissions, there were 268 (0.7%) patients with a total of 319 perforating hollow viscus injuries, 25 (0.07%) of which were blunt gastric injuries. When compared with the small bowel or colon injuries, the blunt gastric injury group had a higher Injury Severity Score (22 versus 17, P = 0.04), more patients with a chest Abbreviated Injury Score greater than 2 (36% versus 12%, P < 0.01), and a shorter interval from injury to laparotomy (221 versus 366 minutes, P = 0.017). Multivariate analysis identified five independent risk factors for mortality: age older than 55 years, head Abbreviated Injury Score greater than 2, chest Abbreviated Injury Score greater than 2, the presence of hypotension on admission, and Glasgow Coma Scale 8 or less. The results of this study suggest that mortality in patients with blunt hollow viscus injuries can be attributed to concurrent head and chest injuries, but not the specific hollow viscus organ that is injured.

Blunt chest injuries (BCI) are associated with high rates of morbidity and mortality. There are many interventions for BCI which may be able to be combined as a care bundle for improved and more consistent outcomes. To review and integrate the BCI management interventions to inform the development of a BCI care bundle. A structured search of the literature was conducted to identify studies evaluating interventions for patients with BCI. Databases MEDLINE, CINAHL, PubMed and Scopus were searched from 1990-April 2017. A two-step data extraction process was conducted using pre-defined data fields, including research quality indicators. Each study was appraised using a quality assessment tool, scored for level of evidence, then data collated into categories. Interventions were also assessed using the APEASE criteria then integrated to develop a BCI care bundle. Eighty-one articles were included in the final analysis. Interventions that improved BCI outcomes were grouped into three categories; respiratory intervention, analgesia and surgical intervention. Respiratory interventions included continuous positive airway pressure and high flow nasal oxygen. Analgesia interventions included regular multi-modal analgesia and paravertebral or epidural analgesia. Surgical fixation was supported for use in moderate to severe rib fractures/BCI. Interventions supported by evidence and that met APEASE criteria were combined into a BCI care bundle with four components: respiratory adjuncts, analgesia, complication prevention, and surgical fixation. The key components of a BCI care bundle are respiratory support, analgesia, complication prevention including chest physiotherapy and surgical fixation. Copyright © 2018 Elsevier Ltd.

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." © Georg Thieme Verlag KG Stuttgart · New York.

Chest trauma is one of the most important causes of death, in particular in individuals under the age of 40 years. The mortality rate for chest trauma, often related to motor vehicle accidents, is approximately 15.5%; it increases dramatically to 77% with associated shock and head injury (Glasgow scores of 3-4). The accurate diagnosis of pathologies consequent to blunt chest trauma depends on a complete knowledge of the different clinical and radiological manifestations. The first diagnostic approach is classically based on chest X-ray often carried out on supine position at the hospital admission. A CT study must then be performed in all chest trauma patients in whom there is even the smallest diagnostic doubt on plain film. In particular, spiral CT (SCT) assumes a fundamental role in the demonstration of mediastinal hemorrhage and direct signs of aortic lesions. At present, SCT is routinely part of a diagnostic evaluation which also includes scans of the brain and the abdomen in polytraumatized patients. Magnetic resonance is the ideal method for visualizing diaphragmatic lesions. Furthermore, recent reports have demonstrated the high diagnostic value of MR in evaluating aortic injuries. The purpose of this article is to review the most common radiological patterns related to chest trauma. (orig.)

The quality of chest compressions along with defibrillation is the cornerstone of cardiopulmonary resuscitation (CPR), which is known to improve the outcome of cardiac arrest. We aimed to investigate the relationship between the compression rate and other CPR quality parameters including compression depth and recoil. A conventional CPR training for lay rescuers was performed 2 weeks before the 'CPR contest'. CPR anytime training kits were distributed to respective participants for self-training on their own in their own time. The participants were tested for two-person CPR in pairs. The quantitative and qualitative data regarding the quality of CPR were collected from a standardised check list and SkillReporter, and compared by the compression rate. A total of 161 teams consisting of 322 students, which includes 116 men and 206 women, participated in the CPR contest. The mean depth and rate for chest compression were 49.0±8.2 mm and 110.2±10.2/min. Significantly deeper chest compression depths were noted at rates over 120/min than those at any other rates (47.0±7.4, 48.8±8.4, 52.3±6.7, p=0.008). Chest compression depth was proportional to chest compression rate (r=0.206, pcompression including chest compression depth and chest recoil by chest compression rate. Further evaluation regarding the upper limit of the chest compression rate is needed to ensure complete full chest wall recoil while maintaining an adequate chest compression depth.

Gunshot wounds (GSW) to the chest are common presentations to trauma centres in South Africa. The clinical management and outcome of GSW to the chest are significantly altered by missile trajectory and the associated anatomical structures injured making them challenging injuries to treat. Currently, the management of GSW chest is based on scant evidence and treatment is typically according to algorithms based largely on the anecdotal experience of high volume institutions and experienced clinicians. Ethical approval was obtained for this study. The Electronic Trauma Health Registry (eTHR) Application of the Trauma Centre at Groote Schuur Hospital in Cape Town was interrogated for the year 2015 for all patients with GSW chest. The data was then analysed using descriptive statistics. A total of 141 patients with GSW to the chest were admitted to the Trauma Centre with a median age of 26 years. More than half of the patients, 53. 2% (n = 75) sustained an isolated GSW to the chest. Overall, 29.1% (n = 41) patients sustained a thoracoabdominal injury, which accounts for a significant higher amount of emergency surgeries compared to patients with non thoracoabdominal injuries (54% vs 15%, p = chest surgery of which 5 patients survived. Overall mortality was 7.1% (n = 10) of which 5 patients died from a thoracic cause. Civilian GSW to the chest are common injuries seen in Cape Town, often with concomitant injuries leading to increased morbidity. Significantly more emergency surgeries were done in patients with thoracoabdominal injury. Overall few patients needed chest-related emergency operative intervention (9.2%) with a survival rate of 38.5%. Overall mortality of patients with GSW chest who reached the hospital was 7.1% of whom 50% died from a thoracic cause.

Cardiogenic shock following blunt chest trauma

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.

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.

Imaging is paramount in the setting of blunt trauma and is now the standard of care at any trauma center. Although anteroposterior radiography has inherent limitations, the ability to acquire a radiograph in the trauma bay with little interruption in clinical survey, monitoring, and treatment, as well as radiography's accepted role in screening for traumatic aortic injury, supports the routine use of chest radiography. Chest CT or CT angiography is the gold-standard routine imaging modality for detecting thoracic injuries caused by blunt trauma. There is disagreement on whether routine chest CT is necessary in all patients with histories of blunt trauma. Ultimately, the frequency and timing of CT chest imaging should be site specific and should depend on the local resources of the trauma center as well as patient status. Ultrasound may be beneficial in the detection of pneumothorax, hemothorax, and pericardial hemorrhage; transesophageal echocardiography is a first-line imaging tool in the setting of suspected cardiac injury. In the blunt trauma setting, MRI and nuclear medicine likely play no role in the acute setting, although these modalities may be helpful as problem-solving tools after initial assessment. 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. Copyright © 2014 American College of Radiology.

2004-01-01

Full Text Available Introduction: Tracheobronchial injuries are uncommon but potentially fatal complication of blunt thoracic trauma harboring a high morbidity and mortality if not diagnosed early . A recent series gleaning cases from four major Trauma Center in Los Angeles nine cases in a seven- year period , but the incidence of these injuries has been increasing recently. This has been attributed to improvement in hospital care and advanced Trauma Centers and earlier diagnosis of such injuries. Disruption of tight main bronchus is more common, such injuries are often associated with rib or clavicular fractures. Findings: Clinical and paraclinical data gathered from records of three patients referred with tracheobronchial injuries during the recent ten years have been reviewed .These include clinical manifestations, diagnostic findings, treatment modality and clinical course. The outcome has been satisfactory in all three patients who have undergone operation 2-5 hours after sustaining the injury. We have not had any mortality. Conclusion: These results are similar to those of other series emphasizing over early diagnosis and treatment of such injuries .

Significant findings: The initial chest x-ray showed an abnormal superior mediastinal contour (blue line, suggestive of a possible aortic injury. The CT angiogram showed extensive circumferential irregularity and outpouching of the distal aortic arch (red arrows compatible with aortic transection. In addition, there was a circumferential intramural hematoma, which extended through the descending aorta to the proximal infrarenal abdominal aorta (green arrow. There was also an extensive surrounding mediastinal hematoma extending around the descending aorta and supraaortic branches (purple arrows. Discussion: Traumatic aortic injury is a life-threatening event. The incidence of blunt thoracic aortic injury is low, between 1 to 2 percent of those patients with blunt thoracic trauma.1 However, approximately 80% of patients with traumatic aortic injury die at the scene.2 Therefore it is imperative to diagnose traumatic aortic injury in a timely fashion. The diagnosis can be difficult due to the non-specific signs and symptoms and other distracting injuries. Clinical suspicion should be based on the mechanism of the injury and the hemodynamic status of the patient. In any patient with blunt or penetrating trauma to the chest that is hemodynamically unstable, traumatic aortic injury should be on the differential. Chest x-ray can be used as a screening tool. A normal chest x-ray has a negative predictive value of approximately 97%. CTA chest is the

Commotion cordis and cardiac injuries are rare events usually following a chest blunt trauma during sports activities. Various aetiologies have been identified to cause electrical (commotion cordis) and/or structural (contusion and further injuries) damage, but high-velocity tools such as baseballs or hockey pucks (also called projectiles) have been chiefly identified. Clinical consequences are challenging, varying from uncomplicated supraventricular arrhythmias to cardiac wall rupture. Ventricular fibrillation is the most remarkable outcome leading to cardiac arrest in some individuals. In this article, up-to-date epidemiological and pathophysiological issues are discussed, along with the most suitable assistance protocols of the injured athlete in the sports arena. Current knowledge about traumatic sports injuries and ensuing cardiovascular sequelae made significant steps forwards than in the past. The majority of athletes (especially the youngest ones) wearing chest protectors are usually preserved from serious outcomes and sudden cardiac death, but further technical effort is encouraged to attain more satisfactory barriers against projectile's impact. Educational campaigns among students, closer team surveillance, implementation of the sports arenas with adequate rescue devices and medical assistance remain mandatory in every sports activity.

Horseback riding is more dangerous than motorcycle riding, skiing, football, and rugby. The purpose of this study was to identify the incidence and injury patterns, as well as risk factors associated with severe equestrian trauma. All patients with major equestrian injuries (injury severity score > or = 12) admitted between 1995 and 2005 were reviewed. A 46-question survey outlining potential rider, animal, and environmental risk factors was administered. Among 7941 trauma patients, 151 (2%) were injured on horseback (mean injury severity score, 20; mortality rate, 7%). Injuries included the chest (54%), head (48%), abdomen (22%), and extremities (17%). Forty-five percent required surgery. Survey results (55%) indicated that riders and horses were well trained, with a 47% recidivism rate. Only 9% of patients wore helmets, however, 64% believed the accident was preventable. Chest trauma previously has been underappreciated. This injury pattern may be a result of significant rider experience. Helmet and vest use will be targeted in future injury prevention strategies.

Large pneumothorax in blunt chest trauma: Is a chest drain always necessary in stable patients? A case report.

Science.gov (United States)

Idris, Baig M; Hefny, Ashraf F

Pneumothorax is the most common potentially life-threatening blunt chest injury. The management of pneumothorax depends upon the etiology, its size and hemodynamic stability of the patient. Most clinicians agree that chest drainage is essential for the management of traumatic large pneumothorax. Herein, we present a case of large pneumothorax in blunt chest trauma patient that resolved spontaneously without a chest drain. A 63- year- old man presented to the Emergency Department complaining of left lateral chest pain due to a fall on his chest at home. On examination, he was hemodynamically stable. An urgent chest X-ray showed evidence of left sided pneumothorax. CT scan of the chest showed pneumothorax of more than 30% of the left hemithorax (around 600ml of air) with multiple left ribs fracture. Patient refused tube thoracostomy and was admitted to surgical department for close observation. The patient was managed conservatively without chest tube insertion. A repeat CT scan of the chest has shown complete resolution of the pneumothorax. The clinical spectrum of pneumothorax varies from asymptomatic to life threatening tension pneumothorax. In stable patients, conservative management can be safe and effective for small pneumothorax. To the best of our knowledge, this is the second reported case in the English literature with large pneumothorax which resolved spontaneously without chest drain. Blunt traumatic large pneumothorax in a clinically stable patient can be managed conservatively. Current recommendations for tube placement may need to be reevaluated. This may reduce morbidity associated with chest tube thoracostomy. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

This paper describes the typical radiologic findings in chest trauma, and the value of conventional radiography, CT, MRI, and aortography is discussed. Conventional radiography rather than cross-sectional imaging is the mainstay in diagnosing thoracic trauma. During the critical phase with often concomitant shock, pelvic and spinal injuries tailored raiographic views or even upright chest radiographs are impractical. The severely traumatized patient is usually radiographed in the supine position and suboptimal roentgenograms may have to be accepted for several reasons. It is well documented that many abnormalities detected on CT were not apparent on conventional radiographs, but CT is reserved for hemodynamical stable patients. Nevertheless certain situations like aortic rupture require further evaluation by CT and aortography. (orig./MG)

On the basis of widely laterally resected anterior chest walls, ossification specimens of female (n=95) and male (n=112) individuals of different age have been examined. An unexpected high significance of the already described sex dimorphism could be secured between the 20th and 50th year of age. The estimated epiphenomenological changes impress as a female calcification type with centrally in the costal cartilage situated ossifications and as a male calcification type with sheath-like calcifications situated at the cranial and caudal edges of the costicartilage.

Chest Tube Drainage of the Pleural Space: A Concise Review for Pulmonologists.

Science.gov (United States)

Porcel, José M

2018-04-01

Chest tube insertion is a common procedure usually done for the purpose of draining accumulated air or fluid in the pleural cavity. Small-bore chest tubes (≤14F) are generally recommended as the first-line therapy for spontaneous pneumothorax in non-ventilated patients and pleural effusions in general, with the possible exception of hemothoraces and malignant effusions (for which an immediate pleurodesis is planned). Large-bore chest drains may be useful for very large air leaks, as well as post-ineffective trial with small-bore drains. Chest tube insertion should be guided by imaging, either bedside ultrasonography or, less commonly, computed tomography. The so-called trocar technique must be avoided. Instead, blunt dissection (for tubes >24F) or the Seldinger technique should be used. All chest tubes are connected to a drainage system device: flutter valve, underwater seal, electronic systems or, for indwelling pleural catheters (IPC), vacuum bottles. The classic, three-bottle drainage system requires either (external) wall suction or gravity ("water seal") drainage (the former not being routinely recommended unless the latter is not effective). The optimal timing for tube removal is still a matter of controversy; however, the use of digital drainage systems facilitates informed and prudent decision-making in that area. A drain-clamping test before tube withdrawal is generally not advocated. Pain, drain blockage and accidental dislodgment are common complications of small-bore drains; the most dreaded complications include organ injury, hemothorax, infections, and re-expansion pulmonary edema. IPC represent a first-line palliative therapy of malignant pleural effusions in many centers. The optimal frequency of drainage, for IPC, has not been formally agreed upon or otherwise officially established. Copyright©2018. The Korean Academy of Tuberculosis and Respiratory Diseases.

Purpose: Relative to photon alternatives, the increased dose-conformity associated with proton therapy is expected to reduce the extent of radiation-induced lung toxicity. However, analysis of follow-up data is yet to be published in this area. In this study we retrospectively analyzed late-phase HU changes for proton therapy cohorts of chest wall and lung patients. Methods: From our institution’s register of patients treated using double-scattered protons, all chest wall and stereotactic lung cases (treated 2011–2012 and 2008–2014 respectively) were initially considered. Follow-up CT data were accessible for 10 chest wall cases (prescribed 50.4 GyRBE in 28 fractions) and 16 lung cases (prescribed 42–50 GyRBE in 3–4 fractions). CT time-points ranged from 0.5–3.5 years post-treatment. Planning doses were recalculated using TOPAS Monte Carlo simulations and mapped onto the follow-up images using deformable registration. Excluding internal target volumes, changes in HU between each patient’s planning and follow-up CT(s) were evaluated for dose bins of 2–30 GyRBE (2 GyRBE increments). Results: Linear increases in HU per unit dose, with correlations statistically significant at the 1% level (one-sided Spearman’s rank test), were evident for all 10 chest wall cases and 14/16 lung cases. The mean changes in HU/Gy were: 1.76 (SD=0.73) for the chest wall cohort, and 1.40 (SD=0.87) for the lung cohort. The median scan times post treatment were 21 and 12 months respectively. All 26 patients developed solid consolidation (scar-like radiographic opacities) within the exposed lung(s). Conclusion: Analysis of follow-up CTs revealed statistically significant correlations in HU-change/dose for two proton cohorts (lung and chest wall). Quantitatively, the late-phase changes we report broadly match published photon data. Further analysis of such radiographic changes, particularly via matched cohort studies drawing upon consistent imaging protocols, could play an

Intrapulmonary percussive ventilation (IPV and high-frequency chest wall oscillation (HFCWO are techniques designed to create a global percussion of the lung which removes secretions and probably clears the peripheral bronchial tree. We tested the hypothesis that adding IPV or HFCWO to the best pharmacological therapy (PT may provide additional clinical benefit over chest physiotherapy in patients with severe COPD. Methods: Sixty patients were randomized into three groups (20 patients in each group: IPV group (treated with PT and IPV, PT group with (treated with PT and HFCWO, and control group (treated with PT alone. Primary outcome measures included results on the dyspnea scale (modified Medical Research Council and Breathlessness, Cough, and Sputum scale (BCSS, as well as an evaluation of daily life activity (COPD Assessment Test [CAT]. Secondary outcome measures were pulmonary function testing, arterial blood gas analysis, and hematological examinations. Moreover, sputum cell counts were performed at the beginning and at the end of the study. Results: Patients in both the IPV group and the HFCWO group showed a significant improvement in the tests of dyspnea and daily life activity evaluations (modified Medical Research Council scale, BCSS, and CAT compared to the control group, as well as in pulmonary function tests (forced vital capacity, forced expiratory volume in 1 second, forced expiratory volume in 1 second/forced vital capacity%, total lung capacity, residual volume, diffusing lung capacity monoxide, maximal inspiratory

Studying morbidity and predicting mortality in patients with blunt chest trauma using a novel clinical score

Full Text Available Background: A departmental audit in March 2015 revealed significant mortality rate of 40% in blunt chest trauma patients (much greater than the global 25%. A study was thus planned to study morbidity and predictors of mortality in blunt chest trauma patients admitted to our hospital. Methods: This study was a prospective observational study of 139 patients with a history of blunt chest trauma between June 2015 and November 2015 after the Institutional Ethics Committee approval in April 2015. The sample size was calculated from the prevalence rate in our institute from the past medical records. Results: The morbidity factors following blunt chest injuries apart from pain were need for Intensive Care Unit stay, mechanical ventilation, and pneumonia/acute respiratory distress syndrome. Significant predictors of mortality in our study were SpO2 16, and need for mechanical ventilation. By calculating the likelihood ratios of each respiratory sign, a clinical score was devised. Conclusion: The modifiable factors affecting morbidity and mortality were identified. Mild to moderate chest injury due to blunt trauma is difficult to diagnose. The restoration of respiratory physiology has not only significant implications on recovery from chest injury but also all other injuries. It is our sincere hope that the score we have formulated will help reduce mortality and morbidity after further trials.

Purpose: To quantify lung perfusion changes after breast/chest wall radiation therapy (RT) using pre- and post-RT single photon emission computed tomography/computed tomography (SPECT/CT) attenuation-corrected perfusion scans; and correlate decreased perfusion with adjuvant RT dose for breast cancer in a prospective clinical trial. Methods and Materials: As part of an institutional review board–approved trial studying the impact of RT technique on lung function in node-positive breast cancer, patients received breast/chest wall and regional nodal irradiation including superior internal mammary node RT to 50 to 52.2 Gy with a boost to the tumor bed/mastectomy scar. All patients underwent quantitative SPECT/CT lung perfusion scanning before RT and 1 year after RT. The SPECT/CT scans were co-registered, and the ratio of decreased perfusion after RT relative to the pre-RT perfusion scan was calculated to allow for direct comparison of SPECT/CT perfusion changes with delivered RT dose. The average ratio of decreased perfusion was calculated in 10-Gy dose increments from 0 to 60 Gy. Results: Fifty patients had complete lung SPECT/CT perfusion data available. No patient developed symptoms consistent with pulmonary toxicity. Nearly all patients demonstrated decreased perfusion in the left lung according to voxel-based analyses. The average ratio of lung perfusion deficits increased for each 10-Gy increment in radiation dose to the lung, with the largest changes in regions of lung that received 50 to 60 Gy (ratio 0.72 [95% confidence interval 0.64-0.79], P<.001) compared with the 0- to 10-Gy region. For each increase in 10 Gy to the left lung, the lung perfusion ratio decreased by 0.06 (P<.001). Conclusions: In the assessment of 50 patients with node-positive breast cancer treated with RT in a prospective clinical trial, decreased lung perfusion by SPECT/CT was demonstrated. Our study allowed for quantification of lung perfusion defects in a prospective cohort of

Chest wall desmoid tumours treated with definitive radiotherapy: a plan comparison of 3D conformal radiotherapy, intensity-modulated radiotherapy and volumetric-modulated arc radiotherapy

Definitive radiotherapy is often used for chest wall desmoid tumours due to size or anatomical location. The delivery of radiotherapy is challenging due to the large size and constraints of normal surrounding structures. We compared the dosimetry of 3D conformal radiotherapy (3DCRT), intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc radiotherapy (VMAT) to evaluate the best treatment option. Ten consecutive patients with inoperable chest wall desmoid tumours (PTV range 416–4549 cm 3 ) were selected. For each patient, 3DCRT, IMRT and VMAT plans were generated and the Conformity Index (CI), organ at risk (OAR) doses and monitor unit (MU) were evaluated. The Wilcoxon signed-rank test was used to compare dose delivered to both target and OARs. The mean number of fields for 3DCRT and IMRT were 6.3 ± 2.1, 7.2 ± 1.8. The mean number of arcs for VMAT was 3.7 ± 1.1. The mean conformity index of VMAT (0.98 ± 0.14) was similar to that of IMRT (1.03 ± 0.13), both of which were significantly better than 3DCRT (1.35 ± 0.20; p = 0.005). The mean dose to lung was significantly higher for 3DCRT (11.9Gy ± 7.9) compared to IMRT (9.4Gy ± 5.4, p = 0.014) and VMAT (8.9Gy ± 4.5, p = 0.017). For the 3 females, the low dose regions in the ipsilateral breast for VMAT were generally less with VMAT. IMRT plans required 1427 ± 532 MU per fraction which was almost 4-fold higher than 3DCRT (313 ± 112, P = 0.005). Compared to IMRT, VMAT plans required 60 % less MU (570 ± 285, P = 0.005). For inoperable chest wall desmoid tumours, VMAT delivered equivalent target coverage when compared to IMRT but required 60 % less MU. Both VMAT and IMRT were superior to 3DCRT in terms of better PTV coverage and sparing of lung tissue

Chest wall thickness (CWT) was estimated in fifty four female nonradiation workers of a monazite processing plant by biometric measurements. The CWT ranged from 4.12 cm to 6.94 cm giving an average of 5.19 ± 0.76 cm. CWT was found to have very good correlation with percent Body Fat and abdominal circumference but poor correlation with Body Mass Index, Body Build Index, Slenderness, age etc. CWT increases with age especially in the upper middle-aged group (> 35 years). A single measurement of abdominal circumference can be used to estimate CWT with 94 % accuracy. A factor of 0.0587 was derived to estimate CWT from abdominal circumference. The study also showed that about 11 % of the subjects were obese. The results obtained will be very useful for the accurate measurement of Low Energy Photons like 239 Pu and 241 Am deposited in the lung. (author)

This study evaluated the dynamic behavior of total and compartmental chest wall volumes [(V{sub CW}) = rib cage (V{sub RC}) + abdomen (V{sub AB})] as measured breath-by-breath by optoelectronic plethysmography during constant-load exercise in patients with stable chronic obstructive pulmonary disease. Thirty males (GOLD stages II-III) underwent a cardiopulmonary exercise test to the limit of tolerance (Tlim) at 75% of peak work rate on an electronically braked cycle ergometer. Exercise-induced dynamic hyperinflation was considered to be present when end-expiratory (EE) V{sub CW} increased in relation to resting values. There was a noticeable heterogeneity in the patterns of V{sub CW} regulation as EEV{sub CW} increased non-linearly in 17/30 “hyperinflators” and decreased in 13/30 “non-hyperinflators” (P < 0.05). EEV{sub AB} decreased slightly in 8 of the “hyperinflators”, thereby reducing and slowing the rate of increase in end-inspiratory (EI) V{sub CW} (P < 0.05). In contrast, decreases in EEV{sub CW} in the “non-hyperinflators” were due to the combination of stable EEV{sub RC} with marked reductions in EEV{sub AB}. These patients showed lower EIV{sub CW} and end-exercise dyspnea scores but longer Tlim than their counterparts (P < 0.05). Dyspnea increased and Tlim decreased non-linearly with a faster rate of increase in EIV{sub CW} regardless of the presence or absence of dynamic hyperinflation (P < 0.001). However, no significant between-group differences were observed in metabolic, pulmonary gas exchange and cardiovascular responses to exercise. Chest wall volumes are continuously regulated during exercise in order to postpone (or even avoid) their migration to higher operating volumes in patients with COPD, a dynamic process that is strongly dependent on the behavior of the abdominal compartment.

Zhang, Feng-Ling; Yan, Li; Huang, Su-Fang; Bai, Xiang-Jun

2013-01-01

Cardiopulmonary resuscitation (CPR) is a kind of emergency treatment for cardiopulmonary arrest, and chest compression is the most important and necessary part of CPR. The American Heart Association published the new Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care in 2010 and demanded for better performance of chest compression practice, especially in compression depth and rate. The current study was to explore the relationship of quality indexes of chest compression and to identify the key points in chest compression training and practice. Totally 219 healthcare workers accepted chest compression training by using Laerdal ACLS advanced life support resuscitation model. The quality indexes of chest compression, including compression hands placement, compression rate, compression depth, and chest wall recoil as well as self-reported fatigue time were monitored by the Laerdal Computer Skills and Reporting System. The quality of chest compression was related to the gender of the compressor. The indexes in males, including self-reported fatigue time, the accuracy of compression depth and the compression rate, the accuracy of compression rate, were higher than those in females. However, the accuracy of chest recoil was higher in females than in males. The quality indexes of chest compression were correlated with each other. The self-reported fatigue time was related to all the indexes except the compression rate. It is necessary to offer CPR training courses regularly. In clinical practice, it might be better to change the practitioner before fatigue, especially for females or weak practitioners. In training projects, more attention should be paid to the control of compression rate, in order to delay the fatigue, guarantee enough compression depth and improve the quality of chest compression.
