    Presenting an abstract and a poster gives scientists from all fields, including psychiatry, an important opportunity to introduce their research to others. Researchers and mental health professionals at all levels of career development can use several media resources to assist them with the technical aspects of preparing an abstract or a poster. This article will focus on major principles associated with preparing and presenting an abstract and a poster at a scientific meeting. A literature search using NIH PubMed was conducted to identify peer and non-peer-reviewed articles that provide methods for effective abstract and poster presentation for the period of 1966 to June 2014. First, we review the purpose and relative importance of abstracts and posters in academic settings. Next, we describe the qualities of an effective abstract and poster and common pitfalls that may occur. Finally, we present a systematic approach to preparing and presenting an abstract and a poster in a scientific setting. Several sources consistently suggest that readability, organization, and succinctness are qualities that make an effective and successful abstract and poster. Mental health professionals in all stages of their career development may benefit from following these guidelines in presenting their scientific work. PMID:25085499

  11. [Management of the patient presenting chest pain].

    PubMed

    Nishio, Susumu; Yamada, Hirotsugu

    2011-12-01

    A variety of diseases cause chest pain. Some entities such as acute coronary syndrome, aortic dissection, and pulmonary embolism are Life-threatening and immediate medical interventions may be required. Acute coronary syndrome is a disease due to disruption of plaque in coronary arteries. The echocardiography can be utilized to diagnose these situation by detecting wall motion abnormalities. Aortic dissection occurs when a tear in the inner wall of the aorta causes blood to flow between the layers of the wall and force the layers apart. The diagnosis can be made by pointing out the intimal flap by echocardiographic examination. A pulmonary embolism is a sudden blockage in a lung artery, which usually caused by a blood clot in a deep vein thrombosis. The echocardiography can prove the existence of pulmonary hypertension and right ventricular over loading. When one performs echocardiography in patients with chest pain in the emergency room, it is important to observe patient's condition, physical findings, and the electrocardiogram. The life-threatening diseases such as acute coronary syndrome, aortic dissection and pulmonary embolism should be considered in the first. If these lethal diseases are ruled out, every possibility including diseases other than cardiovascular disease must be considered. In the emergency echocardiography, incomplete knowledge and skills may lead misdiagnosis and patient's life is threatened. Thus, expert sonographer should perform the examination. The most important issue is to save the patients not to complete the echocardiographic study in this situation.

  16. In the eye of the beholder: making the most of poster presentations--Part 2.

    PubMed

    Crooks, D L; Kilpatrick, M

    1998-08-01

    Poster presentations are an excellent starting point for novice conference presenters and may be less intimidating than oral presentations because the audience is often one-to-one and discussion can flow readily. The poster presenter has worked with the content over a period of time, knows it well and can explain it with knowledge and enthusiasm. Networking with a number of persons in a similar field at the "work in progress" stage benefits the work. Posters may also be displayed in the home agency to facilitate internal communication about a project or study and the accomplishments achieved. Credit may be given to presenters from peers unable to attend the conference and discussion about the project may stimulate internal interest in the process of research (Lynn, 1989). Before developing a poster presentation, adequate consideration must be given to careful planning. Posters can be time-consuming and expensive unless adequate care is taken in the planning stages. With adequate planning and extensive feedback throughout the planning stage, a poster can be a rewarding presentation. PMID:9814152

    PubMed

    Caffery, Terrell; Foy, Matthew

    2014-01-01

    A 33-year-old man presented to the emergency department (ED) with chief complaint of chest pain, persisting for approximately one year. Chest X-ray revealed he was missing the right posterior fifth rib. Physical examination showed no surgical scars, and he reported no history of chest trauma. A CT of his chest demonstrated a mass involving the posterior aspect of the right fifth rib, and subsequent biopsy revealed plasma cells. Laboratory results indicated the tumor was a solitary plasmacytoma of the rib. He was referred to oncology and treated with radiation therapy. This case report illustrates an unusual presentation of a solitary plasmacytoma of the rib.

    Chest pain is a common general practice presentation that requires careful diagnostic assessment because of its diverse and potentially serious causes. However, the evaluation of acute chest pain remains challenging, despite many new insights over the past two decades. The percentage of patients presenting to the emergency departments because of acute chest pain appears to be increasing. Nowadays, there are two essential chest pain-related issues: 1) the missed diagnoses of acute coronary syndromes with a poor short-term prognosis; 2) the increasing percentage of hospitalizations of low-risk cases.It is well known that hospitalization of a low-risk chest pain patient can lead to unnecessary tests and procedures, with an increasing trend of complications and burden of costs. Therefore, the significantly reduced financial resources of healthcare systems induce physicians and administrators to improve the efficiency of care protocols for patients with acute chest pain. Despite the efforts of the Scientific Societies in producing statements on this topic, in Italy there is still a significant difference between emergency physicians and cardiologists in managing patients with chest pain. For this reason, the aim of the present consensus document is double: first, to review the evidence-based efficacy and utility of various diagnostic tools, and, second, to delineate the critical pathways (describing key steps) that need to be implemented in order to standardize the management of chest pain patients, making a correct diagnosis and treatment as uniform as possible across the entire country.

  4. A poster presentation as an evaluation method to facilitate reflective thinking skills in nursing education.

    PubMed

    Chabeli, M M

    2002-08-01

    This article seeks to establish whether the poster presentation of a specific theme can facilitate the student's thinking skills in nursing education. A qualitative, exploratory, descriptive and contextual research design where twenty students volunteered to take part in the study by signing an informed consent was followed. Descriptive naïve sketches were used for data collection followed by individual interviews to validate the findings. Data was analysed by means of the descriptive method of open coding of Tesch (in Creswell, 1994:155). DENOSA's ethical standards for research (1998:7) were considered. The findings indicated both positive and negative perceptions. The positive perceptions were: a poster presentation as an evaluation method facilitates creative, critical and reflective thinking skills; group work facilitates student participation; it facilitates problem solving skills; it increases the student's independence and a sense of ownership; and the evaluation is fair. The negative perceptions were that there was a lack of clarity on the student's expectations and that group activity is difficult. Trustworthiness was maintained in accordance with Lincoln and Guba's principles (1985:290-327). It is concluded that a poster presentation, used effectively as an evaluation method, can facilitate the learner's critical and reflective thinking skills. It is recommended that other learner-centred methods of assessment and evaluation be researched for their effective use in facilitating the higher order thinking skills of learners.

    Spinal metastases may present in a myriad of ways, most commonly back pain with or without neurology. We report an unusual presentation of isolated atypical chest pain preceding metastatic cord compression, secondary to penile carcinoma. Spinal metastasis from penile carcinoma is rare with few cases reported. This unusual presentation highlights the need for a heightened level of clinical suspicion for spinal metastases as a possible cause for chest pain in any patients with a history of carcinoma. The case is discussed with reference to the literature. PMID:27429829

    Although many students conduct research with faculty in organized summer programs or as part of their course work or their degree work, they often face barriers to traveling to present that research, especially at national or international conferences. This is especially true for students who are members of underrepresented minority populations and students studying outside of the United States. A new and exciting opportunity for undergraduate as well as graduate students to showcase their work is now available. AGU piloted three opportunities for an undergraduate and graduate virtual poster showcase in the fall of 2015. Student participants were recruited from a diverse array of groups including minority-serving organizations, two-year colleges, and internship programs at federal agencies and national laboratories. Students uploaded an abstract, poster, and short video explain their research, and then participated in Q&A sessions with peers as well as expert judges. This presentation will share characteristics of participating groups, lessons learned from this new program, and preliminary evaluation findings as well as plans for the future.

    2016-01-01

    A diagnosis of ‘chronic cough’ (CC) requires the exclusion of sinister pulmonary pathology, including infection and malignancy. We present a patient with a 3 month history of CC who had an extensive workup including a normal high resolution computed tomography of the chest (HRCT) 6 weeks prior to consultation at our center. He subsequently developed constitutional symptoms including weight loss and loss of appetite 5 weeks after initial consultation. A repeat HRCT chest and a subsequent whole body PET scan found that he had developed extensive pulmonary lymphangitic carcinomatosis (PLC) from a colon primary. Treatment of the colon cancer resulted in significant decrease in metastatic disease burden and cough resolution. PLC is a very rare cause of ‘chronic cough’ and incipient/occult PLC presenting with chronic cough and a normal initial HRCT chest has not been previously reported. PMID:26958342

    2004-12-01

    Electron beam computed tomography (EBCT) is a unique, noninvasive radiologic method capable of high-resolution imaging that is being increasingly used for evaluation of the cardiovascular system. Among its multiple applications, coronary artery calcium (CAC) imaging has attracted considerable attention because of the potential of this technique for early detection of coronary artery disease (CAD), the leading cause of mortality in our society. Although measurement of CAC has been primarily performed in the outpatient setting in both symptomatic and asymptomatic subjects, several studies have assessed the utility of the method to identify CAD in patients presenting to the emergency department with chest pain suggestive of myocardial ischemia but without objective evidence of the latter. This group comprises a majority of those presenting to the emergency department with chest pain, and their safe, accurate and cost-effective evaluation has been a continuing challenge. PMID:18340176

    A previously well 71-year-old woman presented to the Emergency Department with acute-onset left-sided chest pain. She was haemodynamically stable with unremarkable systemic examination. Her electrocardiogram and troponin were within normal limits and her chest radiograph showed a raised left hemi-diaphragm. Two hours after admission, this woman became acutely breathless, and suffered a pulseless electrical activity cardiac arrest. After cardiopulmonary resuscitation, there was a return of spontaneous circulation and regained consciousness. A repeat clinical assessment revealed a new left-sided dullness to percussion with contralateral percussive resonance on respiratory examination. CXR revealed a left pan-hemi-thoracic opacity whilst better definition using CT-pulmonary angiography (CTPA) indicated an acute tension gastrothorax secondary to a large left-sided diaphragmatic hernia. Nasogastric (NG) tube insertion was used to decompress the stomach and the patient underwent uncomplicated emergency laparoscopic hernia reduction. She remained well at 1-year follow-up.

  13. Electromagnetic oil field mapping for improved process monitoring and reservoir characterization: A poster presentation

    SciTech Connect

    Waggoner, J.R.; Mansure, A.J.

    1992-02-01

    This report is a permanent record of a poster paper presented by the authors at the Third International Reservoir Characterization Technical Conference in Tulsa, Oklahoma on November 3--5, 1991. The subject is electromagnetic (EM) techniques that are being developed to monitor oil recovery processes to improve overall process performance. The potential impact of EM surveys is very significant, primarily in the areas of locating oil, identifying oil inside and outside the pattern, characterizing flow units, and pseudo-real time process control to optimize process performance and efficiency. Since a map of resistivity alone has little direct application to these areas, an essential part of the EM technique is understanding the relationship between the process and the formation resistivity at all scales, and integrating this understanding into reservoir characterization and simulation. First is a discussion of work completed on the core scale petrophysics of resistivity changes in an oil recovery process; a steamflood is used as an example. A system has been developed for coupling the petrophysics of resistivity with reservoir simulation to simulate the formation resistivity structure arising from a recovery process. Preliminary results are given for an investigation into the effect of heterogeneity and anisotropy on the EM technique, as well as the use of the resistivity simulator to interpret EM data in terms of reservoir and process parameters. Examples illustrate the application of the EM technique to improve process monitoring and reservoir characterization.

    Identification of patients at low risk presenting to the emergency department with chest pain is a continuing challenge. We examined a cohort of low-risk women with negative cardiac injury markers, electrocardiogram with normal results, and clinical stability. We hypothesized that these patients can be safely and accurately managed in a chest pain unit (CPU), may not require predischarge cardiac testing, and have an excellent short-term prognosis. The primary end point was major cardiovascular events during index admission or follow-up. Mean age of the 403 women was 42 ± 4.3 years (30 to 50 years). No patient had a cardiovascular event in the CPU, and none of the 321 patients followed for 6 months had a late cardiovascular event. Most (211, 52%) did not receive predischarge cardiac testing. The remaining 192 patients (48%) had predischarge exercise treadmill test, stress imaging, or cardiac catheterization. Of those patients who underwent treadmill testing, almost 90% had no exercise-induced chest pain and approximately 50% had functional capacity 8 to 14 METs. In addition, 166 patients (41%) were discharged from the CPU after <2 hours and 21% (n = 86) within 2 to 8 hours. In conclusion, this group of low-risk women was safely and accurately managed in the CPU and discharged promptly. There were no cardiac events on index admission or 6-month follow-up, and in most patients, predischarge cardiac testing was unnecessary.

    Plasma cell leukemia (PCL) is an uncommon neoplasm of plasma cells, with an aggressive clinical course and poor outcome, even with current standard of care. It can occur either de novo (primary PCL) or as a progression of multiple myeloma (MM). This disease has unique diagnostic criteria but certain genetic markers and clinical features may overlap with MM. Due to the low prevalence of PCL, guidelines on its management are extrapolated from the management of MM and based on small retrospective studies and cases reports/series. We present an interesting case of PCL in a middle-aged African-American male, who was diagnosed incidentally after chest wall imaging for an unrelated complaint. The diagnostic approach, management and outcomes of PCL are discussed. PMID:27462235

    Accurate prognostic information is important in determining optimal management of patients presenting for evaluation of chest pain. In this study, the ability of exercise thallium-201 myocardial imaging to predict future cardiac events (cardiovascular death or nonfatal myocardial infarction) was correlated with clinical, coronary and left ventricular angiographic and exercise electrocardiographic data in 139 consecutive, nonsurgically managed patients followed-up over a 3 to 5 year period (mean follow-up, 3.7 +/- 0.9), using a logistic regression analysis. Among patients without prior myocardial infarction (100 of 139), the number of myocardial segments with transient thallium-201 defects was the only statistically significant predictor of future cardiac events when all patient variables were evaluated. Among patients with myocardial infarction before evaluation (39 of 139), angiographic ejection fraction was the only significant predictor of future cardiac events when all variables were considered. This study suggests an approach to evaluate the risk of future cardiac events in patients with possible ischemic heart disease.

  7. Newer imaging methods for triaging patients presenting to the emergency department with chest pain.

    2005-11-01

    The usefulness of electron beam CT (EBCT) for the risk stratification of patients in the emergency department (ED) who have possible acute coronary syndrome has been evaluated in three small studies. The results of these studies are promising, as patients who have no coronary calcium detected by EBCT essentially had no adverse cardiac events. Although the negative predictive value of EBCT was excellent, the limited positive predictive value that would lead to further diagnostic testing makes this strategy less attractivei f applied to a broad population. Further larger studies may help define which patients in the ED who have chest pain and nondiagnostic ECGs can be effectively evaluated by EBCT. Recent advances in noninvasive coronary angiography by multislice computed tomography are of considerable interest in the ED evaluation of patients with undefined chest pain, but the utility of this method in this setting awaits clinical studies.

    Coronary embolism from a prosthetic heart valve is a rare but remarkable cause of acute coronary syndrome. There is no definite management of an entity like this. Here we report a case of 54-year-old male with a history of rheumatic heart disease with dual prosthetic heart valve and atrial fibrillation who developed chest pain from acute myocardial infarction. The laboratory values showed inadequate anticoagulation. Cardiac catheterization and thrombectomy with the aspiration catheter were chosen to be the treatment for this patient, and it showed satisfactory outcome. PMID:25785203

  12. Nobel Prize Recipient Eric Betzig Presents Lecture on Efforts to Improve High-Resolution Microscopy | Poster

    Cancer.gov

    Eric Betzig, Ph.D., a 2014 recipient of the Nobel Prize in Chemistry and a scientist at Janelia Research Campus (JRC), Howard Hughes Medical Institute, in Ashburn, Va., visited NCI at Frederick on Sept. 10 to present a Distinguished Scientist lecture and discuss the latest high-resolution microscopy techniques. Betzig co-invented photoactivation localization microscopy (PALM) in collaboration with scientists at NIH. PALM achieves 10-fold improvement in spatial resolution of cells, going from the resolution limit of approximately 250 nm in standard optical microscopy down to approximately 20 nm, thus producing a so-called “super-resolution” image. Spatial resolution refers to the clarity of an image or, in other words, the smallest details that can be observed from an image.

  13. L-band Dielectric Constant Measurements of Seawater (Oral presentation and SMOS Poster)

    NASA Technical Reports Server (NTRS)

    Lang, Roger H.; Utku, Cuneyt; LeVine, David M.

    2003-01-01

    This paper describes a resonant cavity technique for the measurement of the dielectric constant of seawater as a function of its salinity. Accurate relationships between salinity and dielectric constant (which determines emissivity) are needed for sensor systems such as SMOS and Aquarius that will monitor salinity from space in the near future. The purpose of the new measurements is to establish the dependence of the dielectric constant of seawater on salinity in contemporary units (e.g. psu) and to take advantage of modern instrumentation to increase the accuracy of these measurements. The measurement device is a brass cylindrical cavity 16cm in diameter and 7cm in height. The seawater is introduced into the cavity through a slender glass tube having an inner diameter of 0.1 mm. By assuming that this small amount of seawater slightly perturbs the internal fields in the cavity, perturbation theory can be employed. A simple formula results relating the real part of the dielectric constant to the change in resonant frequency of the cavity. In a similar manner, the imaginary part of the dielectric constant is related to the change in the cavity s Q. The expected accuracy of the cavity technique is better than 1% for the real part and 1 to 2% for the imaginary part. Presently, measurements of methanol have been made and agree with precision measurements in the literature to within 1% in both real and imaginary parts. Measurements have been made of the dielectric constant of seawater samples from Ocean Scientific in the United Kingdom with salinities of 10, 30, 35 and 38 psu. All measurements were made at room temperature. Plans to make measurements at a range of temperatures and salinities will be discussed.

    Objective The purpose of this case report is to describe the clinical presentation and chiropractic management of Tietze syndrome. Clinical Features A 34-year-old woman presented with unexplained left-sided chest pain. Electrocardiogram and radiographs were taken at a medical emergency department to rule out cardiovascular and pulmonary causes, and pain medication did not relieve her pain. Physical examination showed tenderness on palpation and swelling of the second and third chondrosternal joints, as well as thoracic joint dysfunction. Heart and lung pathology was ruled out, and chondrosternal joint swelling was present, Tietze syndrome was diagnosed. Intervention and Outcome A treatment plan aimed at restoring normal thoracic and rib joint movement and decreasing inflammation of the chondrosternal joints resulted in lower pain levels. Treatment consisted of diversified high-velocity, low-amplitude chiropractic manipulation; activator technique; and cryotherapy. Conclusion Chiropractic management of Tietze syndrome was successful in reducing pain levels in this patient's case. PMID:22027210

    Objectives The recognition of coronary artery disease (CAD) among patients who report chest pain remains difficult in primary care. This study investigates the association between chest pain (specified, unspecified or musculoskeletal) and prodromes (dyspepsia, fatigue or dyspnoea), with first-ever acute CAD, and increased longer term cardiovascular risk. Design Cohort study. Setting Anonymised clinical data recorded electronically by general practitioners from 140 primary care surgeries in London (UK) between April 2008 and April 2013. Participants Data were extracted for all patients aged 30 years and over at the beginning of the study period, registered in the surgeries. Main outcome measures Clinical data included chest pain, dyspepsia, dyspnoea and fatigue, first-ever CAD and long-term cardiovascular risk (QRisk2). Regression models were used to analyse the association between chest pain together with prodromes and CAD and QRisk2≥20%. Results 354 052 patients were included in the study. 4842 patients had first-ever CAD of which 270 reported chest pain in the year before the acute event. 257 019 patients had QRisk2 estimations. Chest pain was associated with a higher risk of CAD. HRs: 21.12 (16.68 to 26.76), p<0.001; 7.51 (6.49 to 8.68), p<0.001; and 1.84 (1.14 to 3.00), p<0.001 for specified, unspecified and musculoskeletal chest pain. Dyspepsia, dyspnoea or fatigue was also associated with a higher risk of CAD. Chest pain of all subtypes, dyspepsia and dyspnoea were also associated with an increased 10-year cardiovascular risk of 20% or more. Conclusions All patients with chest pain, including those with atypical symptoms, require careful assessment for acute and longer term cardiovascular risk. Prodromes may have independent diagnostic value in the estimation of cardiovascular disease risk. PMID:25877275

    We report the case of catastrophic antiphospholipid syndrome (CAPS) complicated with mixed connective tissue disease (MCTD). A female patient was diagnosed with acute interstitial pneumonia (AIP) with MCTD by chest CT scan. Corticosteroid therapy was refractory for lung involvement, and she died due to acute respiratory failure. The autopsy revealed that AIP was compatible with lung involvement of CAPS. We therefore suggest that chest CT might reveal AIP-like findings in CAPS patients whose condition is complicated with pulmonary manifestations.

  1. The Inflatable Poster

    NASA Astrophysics Data System (ADS)

    Tackley, P. J.

    2004-12-01

    Inflatable devices are frequently used in advertising in order to grab the attention of consumers: one sees, for example, 20 foot tall inflatable drink containers, inflatable cell phones, inflatable bubble gum packets, as well as blimps wafting majestically over major sports events. More usefully, inflatable representations of scientifically-interesting items are widely available, including astronauts, space shuttles, dinosaurs and globes and can help to build and inspire the interest of the general public, and in particular children, in such ideas. How can such concepts be adapted to improve poster presentations? Possibility one is to use relevant existing commercially-available inflatables to dress the poster: skeletons, astronauts, globes and so forth. More exciting is to develop custom inflatables that represent three-dimensional renderings of objects that the poster is describing. Examples of individual objects might be an inflatable slab, inflatable avalanche, inflatable plume, or it's larger cousin, the 10 foot high inflatable superplume or 20 foot high inflatable megaplume. More elaborately, inflatables might represent isosurfaces in three-dimensional spherical convection, although other fabrication methods may be more suitable. More simply, inflatable spheres could be imprinted with the planform of convection, geoid, or other spherical fields of geophysical interest. Finally, it should be possible to put an entire poster on an inflatable object, possibly small ones (balloons) to hand out. A major concern, however, is that the presenter may use such techniques to inflate their scientific findings, or to present overblown ideas.

  3. Do Immature Platelet Levels in Chest Pain Patients Presenting to the Emergency Department Aid in the Diagnosis of Acute Coronary Syndrome?

    PubMed Central

    Berny-Lang, Michelle A.; Darling, Chad E.; Frelinger, Andrew L.; Barnard, Marc R.; Smith, Craig S.; Michelson, Alan D.

    2014-01-01

    Introduction Early and accurate identification of acute coronary syndrome (ACS) versus non-cardiac chest pain in patients presenting to the emergency department (ED) is problematic and new diagnostic markers are needed. Previous studies reported that elevated mean platelet volume (MPV) is associated with ACS and predictive of cardiovascular risk. MPV is closely related to the immature platelet fraction (IPF), and recent studies have suggested that IPF may be a more sensitive marker of ACS than MPV. The objective of the present study was to determine if the measurement of IPF assists in the diagnosis of ACS in patients presenting to the ED with chest pain. Methods In this single-center, prospective, cross-sectional study, adult patients presenting to the ED with chest pain and/or suspected ACS were considered for enrollment. Blood samples from 236 ACS-negative and 44 ACS-positive patients were analyzed in a Sysmex XE-2100 for platelet count, MPV, IPF and the absolute count of immature platelets (IPC). Results Total platelet counts, MPV, IPF and IPC were not statistically different between ACS-negative and -positive patients. The IPF was 4.6 ± 2.7 and 5.0 ± 2.8% (mean ± SD, p = 0.24) and the IPC was 10.0 ± 4.6 and 11.5 ± 7.5 × 103/µL (p = 0.27) for ACS-negative and ACS-positive patients, respectively. Conclusion In 280 patients presenting to the ED with chest pain and/or suspected ACS, no differences in IPF, IPC or MPV were observed in ACS-negative versus ACS-positive patients, suggesting that these parameters do not assist in the diagnosis of ACS.

    2015-01-01

    462 patients presenting with chest pain to a rural district general hospital underwent calcium scoring and pretest clinical risk assessment in order to stratify subsequent investigations and treatment was retrospectively reviewed. The patients were followed up for two years and further investigations and outcomes recorded. Of the 206 patients with zero calcium score, 132 patients were immediately discharged from cardiac follow-up with no further investigation on the basis of their calcium score, low pretest risk of coronary artery disease, and no significant incidental findings. After further tests, 267 patients were discharged with no further cardiac therapy, 88 patients were discharged with additional medical therapy, and 19 patients underwent coronary artery by-pass grafting or percutaneous intervention. 164 patients with incidental findings on the chest CT (computed tomography) accompanying calcium scoring were reviewed, of which 88 patients underwent further tests and follow-up for noncardiac causes of chest pain. The correlations between all major risk factors and calcium scores were weak except for a combination of diabetes and hypertension in the male gender (P = 0.012), The use of calcium scoring and pretest risk appeared to reduce the number of unnecessary cardiac investigations in our patients: however, the calcium scoring test produced a high number of incidental findings on the associated CT scans.

    Chest imaging has a central role in the diagnosis and monitoring of sarcoidosis. For staging of pulmonary disease on chest radiograph, Scadding stages are still widely used. High-resolution CT (HRCT), however, is more accurate in visualizing the various manifestations of pulmonary sarcoidosis as well its complications. A generally accepted HRCT scoring system is lacking. Fluorodeoxyglucose F 18 positron emission tomography can visualize disease activity better than conventional makers in a significant proportion of patients. In patients with extensive changes on HRCT but no parenchymal fluorodeoxyglucose F 18 uptake, prudence with regard to initiation or intensification of immunosuppressive treatment is warranted.

  16. Posters that foster cognition in the classroom: Multimedia theory applied to educational posters

    NASA Astrophysics Data System (ADS)

    Hubenthal, M.; O'Brien, T.; Taber, J.

    2011-12-01

    Despite a decline in popularity within U.S. society, posters continue to hold a prominent place within middle and high school science classrooms. Teachers' demand for posters is largely satisfied by governmental and non-profit science organizations' education and public outreach (EPO) efforts. Here, posters are produced and disseminated as both tangible products resulting from the organization's research, and instruments to communicate scientific content to teachers and students. This study investigates the taken-for-granted good of posters through a survey/interview of science teachers who received sample posters at professional development workshops. The design of sample EPO posters were also examined for their implied, underlying assumptions about learning and their alignment to the setting of the classroom, which is unique for the genera of posters. Based on this analysis we found that rates of poster use were as low as 43% and that many EPO posters fail to achieve their potential as an instructional instrument. As a result, many EPO posters are relegated to merely a collection of pretty pictures on the wall. Leveraging existing research in both cognition and the cognitive theory of Multimedia learning, we propose a design framework for educational posters that is likely to activate students' attention, catalyze cognitive processing, provide a framework to guide students' construction of knowledge, and connect to extended learning through live or web-based exploration of phenomenon. While work to examine the implications of this framework is still on-going, we present a prototype poster and supporting website developed using the framework as a guide, as well as results from focus group discussions with classroom practitioners regarding the prototype poster and its potential in the classroom.

  17. Coronary computed tomography angiography (CCTA) and cardiac magnetic resonance (CMR) imaging in the assessment of patients presenting with chest pain suspected for acute coronary syndrome

    Acute chest pain is an important clinical challenge and a major reason for presentation to the emergency department. Although multiple imaging techniques are available to assess patients with suspected acute coronary syndrome (ACS), considerable interest has been focused on the use of non-invasive imaging options as coronary computed tomography angiography (CCTA) and cardiac magnetic resonance (CMR). According to several recent evidences, CCTA has been shown to represent a useful tool to rapidly and accurately diagnose coronary artery disease (CAD) in patients with low to intermediate cardiovascular risk. CCTA examination has the unique ability to non-invasively depict the coronary anatomy, not only allowing visualization of the lumen of the arteries in order to detect severe stenosis or occlusion responsible of myocardial ischemia, but also allows the assessment of coronary artery wall by demonstrating the presence or absence of CAD. However, routine CCTA is not able to differentiate ischemic from non-ischemic chest pain in patients with known CAD and it does not provide any functional assessment of the heart. Conversely, CMR is considered the gold standard in the evaluation of morphology, function, viability and tissue characterization of the heart. CMR offers a wide range of tools for diagnosing myocardial infarction (MI) at least at the same time of the elevation of cardiac troponin values, differentiating infarct tissue and ischemic myocardium from normal myocardium or mimicking conditions, and distinguishing between new and old ischemic events. In high-risk patients, with acute and chronic manifestations of CAD, CMR may be preferable to CCTA, since it would allow detection, differential diagnosis, prognostic evaluation and management of MI.

Here, we report a case of a 48-year-old man with a recent onset of chest pain and palpitations followed by syncope. Holter monitoring documented 2 episodes of evolving ST elevation associated with non-sustained ventricular tachycardia. Emergent cardiac catheterization indicated insignificant coronary narrowing. A non-invasive brachial artery ultrasound, which demonstrated endothelial dysfunction that was salvaged by exogenic nitrate, was used instead of intracoronary provocation. There was no clinical or electrocardiographic recurrence of variant angina after vasodilator treatment. In conclusion, variant angina represents an important but overlooked etiology for syncope. Holter monitoring facilitates the diagnostic and prognostic assessment in patients with syncope precipitated by chest pain. PMID:27122877

    The author comments on the report by Dr. Akbar Panju and associates (see pages 541 to 547 of this issue) on patient outcomes associated with a discharge diagnosis of "chest pain not yet diagnosed." Acute chest pain without evidence of cardiac involvement presents a diagnostic challenge for the clinician, particularly in the present climate of cost containment. Esophageal disorders and psychiatric conditions appear to be the most prevalent causes of noncardiac chest pain. Although screening by means of electrocardiography and cardiac enzyme testing may rule out acute ischemia, and other tests may clearly point to a gastrointestinal cause, it is possible for cardiac and gastrointestinal problems to present simultaneously. Understanding and managing persistent chest pain even after a diagnosis has been made continues to challenge clinicians and researchers, and further progress in this area will depend on multidisciplinary collaboration.

  9. Noncardiac chest pain: epidemiology, natural course and pathogenesis.

    PubMed

    Fass, Ronnie; Achem, Sami R

    2011-04-01

    Noncardiac chest pain is defined as recurrent chest pain that is indistinguishable from ischemic heart pain after a reasonable workup has excluded a cardiac cause. Noncardiac chest pain is a prevalent disorder resulting in high healthcare utilization and significant work absenteeism. However, despite its chronic nature, noncardiac chest pain has no impact on patients' mortality. The main underlying mechanisms include gastroesophageal reflux, esophageal dysmotility and esophageal hypersensitivity. Gastroesophageal reflux disease is likely the most common cause of noncardiac chest pain. Esophageal dysmotility affects only the minority of noncardiac chest pain patients. Esophageal hypersensitivity may be present in non-GERD-related noncardiac chest pain patients regardless if esophageal dysmotility is present or absent. Psychological co-morbidities such as panic disorder, anxiety, and depression are also common in noncardiac chest pain patients and often modulate patients' perception of disease severity.

    Purpose To evaluate the diagnostic yield of recommended chest computed tomography (CT) prompted by abnormalities detected on outpatient chest radiographic images. Materials and Methods This HIPAA-compliant study had institutional review board approval; informed consent was waived. Reports of all outpatient chest radiographic examinations performed at a large academic center during 2008 (n = 29 138) were queried to identify studies that included a recommendation for a chest CT imaging. The radiology information system was queried for these patients to determine if a chest CT examination was obtained within 1 year of the index radiographic examination that contained the recommendation. For chest CT examinations obtained within 1 year of the index chest radiographic examination and that met inclusion criteria, chest CT images were reviewed to determine if there was an abnormality that corresponded to the chest radiographic finding that prompted the recommendation. All corresponding abnormalities were categorized as clinically relevant or not clinically relevant, based on whether further work-up or treatment was warranted. Groups were compared by using t test and Fisher exact test with a Bonferroni correction applied for multiple comparisons. Results There were 4.5% (1316 of 29138 [95% confidence interval {CI}: 4.3%, 4.8%]) of outpatient chest radiographic examinations that contained a recommendation for chest CT examination, and increasing patient age (P < .001) and positive smoking history (P = .001) were associated with increased likelihood of a recommendation for chest CT examination. Of patients within this subset who met inclusion criteria, 65.4% (691 of 1057 [95% CI: 62.4%, 68.2%) underwent a chest CT examination within the year after the index chest radiographic examination. Clinically relevant corresponding abnormalities were present on chest CT images in 41.4% (286 of 691 [95% CI: 37.7%, 45.2%]) of cases, nonclinically relevant corresponding abnormalities in

    Chest trauma is one important factor for total morbidity and mortality in traumatized emergency patients. The complexity of injury in trauma patients makes it challenging to provide an optimal oxygenation while protecting the lung from further ventilator-induced injury to it. On the other hand, lung trauma needs to be treated on an individual basis, depending on the magnitude, location and type of lung or chest injury. Several aspects of ventilatory management in emergency patients are summarized herein and may give the clinician an overview of the treatment possibilities for chest trauma victims. PMID:21769213

    Several non-invasive imaging techniques are currently in use for the diagnostic workup of adult patients with stable chest pain suspected of having coronary artery disease (CAD). In this paper, we present a systematic overview of the evidence on diagnostic performance and comparative cost-effectiveness of new modalities in comparison to established technologies. A literature search for English language studies from 2009 to 2013 was performed, and two investigators independently extracted data on patient and study characteristics. The reviewed published evidence on diagnostic performance and cost-effectiveness support a strategy of CTCA as a rule out (gatekeeper) test of CAD in low- to intermediate-risk patients since it has excellent diagnostic performance and as initial imaging test is cost-effective under different willingness-to-pay thresholds. More cost-effectiveness research is needed in order to define the role and choice of cardiac stress imaging tests. PMID:25301401

    Chest pain is a common symptom in patients who visit Emergency Departments. The main task is to exclude life-threatening diseases such as acute coronary syndrome, pulmonary embolization and dissection of thoracic aorta. The authors present the history of a patient, who had an intense chest pain for 7 hours. In accordance with the diagnostic algorithm of chest pain, ECG, blood collection, chest X-ray and chest computed tomography angiography were performed. Acute coronary syndrome, pulmonary embolization and dissection of the thoracic aorta were excluded, however, chest computed tomography CT revealed a huge hiatal hernia as an incidental finding. An emergency surgical repair was performed and the patient recovered without any complications. The authors emphasize that the diagnostic algorithms focus on the confirmation or rejection of possible life threatening diseases in case of chest pain. However, it should be kept in mind that rarer causes may occur, which may require involvement of the relevant disciplines and multidisciplinary thinking. Orv. Hetil., 2016, 157(36), 1445-1448.

    Bindon, Susan L; Davenport, Joan M

    2013-01-01

    Professional posters play an important role in the dissemination of knowledge and the professional development of advanced practice nurses, graduate students, and clinical faculty. Posters should be considered an integral component in communication of professional work in practice, research, and education. The invitation to submit a poster abstract is an important opportunity for clinicians and faculty alike to consider. Though sometimes misperceived as less prestigious than a podium presentation, posters add a unique element to professional and academic events. The argument is made for posters as an equal among scholarly presentation formats. The poster serves as a tremendous opportunity for collaboration between partners and a way to communicate important findings and advertise the presenters' work. For the advanced practice nurse who is a novice in presenting best practice or evidence from research trials, the poster format may be less intimidating while allowing the invaluable sharing of results. Four critical elements of professional poster development are deciding on a clear Purpose, targeting the right People, outlining key steps in the Process, and delivering a memorable Presentation. Using the "4 Ps" as cornerstones for the work of developing, preparing, and delivering the poster to an audience, the authors aim to help organize the entire process into these essential considerations. The poster, as a means of scholarly work, is a viable and essential activity, as interdisciplinary collaboration and sharing of best practice becomes the expectation for all professional development.

    1985-01-01

    The musculoskeletal structures of the thoracic wall and the neck are a relatively common source of chest pain. Pain arising from these structures is often mistaken for angina pectoris, pleurisy or other serious disorders. In this article the clinical features, pathogenesis and management of the various musculoskeletal chest wall disorders are discussed. The more common causes are costochondritis, traumatic muscle pain, trauma to the chest wall, “fibrositis” syndrome, referred pain, psychogenic regional pain syndrome, and arthritis involving articulations of the sternum, ribs and thoracic spine. Careful analysis of the history, physical findings and results of investigation is essential for precise diagnosis and effective treatment. ImagesFig. 3Fig. 4Fig. 5 PMID:4027804

    Objective To implement and assess a required public health poster project in a doctor of pharmacy (PharmD) program. Design Third-year PharmD students collaborated in pairs to research a public health topic relating to pharmacy practice. Each student group prepared an informational poster, while receiving feedback from a faculty mentor at each stage of the project. The students presented their completed posters at a statewide pharmacy conference. Assessment Faculty members evaluated the posters with a grading rubric, and students completed a survey instrument that assessed the overall experience. In general, faculty members rated the class highly across all domains of the grading rubric. The class generally agreed that the poster project increased their awareness of public health issues related to pharmacy practice, overall knowledge of public health, and presentation skills. Conclusion The implementation of a poster project was well received by students and faculty members as an effective method for enhancing public health instruction in the PharmD program at North Dakota State University.

    A 58-year old patient on dialysis for four years due to chronic renal failure presented with complaints of painless, continuously growing swelling on the left of his back and coughing, symptoms evolving over a period of approximately 3 months. Physical examination revealed a soft fixed mass of 10 x 10 x 4 cm on the left infrascapular area on the chest wall. The sample taken from the inflammation on the chest wall was analyzed with PCR method which resulted positive for Acid Fast Bacilli (AFB), tissue biopsy showed dermatitis with granulomata and sputum was positive for AFB. Thoracic MR, performed for the purpose of detecting the relationship between the lesion on the lung and the one on the chest wall, detected changes in the inflammatory soft tissues and multiple small abscess formations on the chest wall. There was no pathological signal in the bone structures of the chest wall. This case underlines the necessity to include "Empyema necessitatis" in the preliminary diagnosis when there is a soft tissue swelling on the chest wall without inflammatory signs in patients with reduced immune defences.

There are 7 level III ecoregions and 52 level IV ecoregions in Arizona and many continue into ecologically similar parts of adjacent states. This poster is part of a collaborative project primarily between the U.S. Geological Survey (USGS), USEPA National Health and Environmental Effects Research Laboratory (Corvallis, Oregon), USEPA Region IX, U.S. Department of Agriculture (USDA)–Natural Resources Conservation Service (NRCS), The Nature Conservancy, and several Arizona state agencies. The project is associated with an interagency effort to develop a common national framework of ecological regions. Reaching that objective requires recognition of the differences in the conceptual approaches and mapping methodologies applied to develop the most common ecoregion-type frameworks, including those developed by the USDA–Forest Service, the USEPA, and the NRCS. As each of these frameworks is further refined, their differences are becoming less discernible. Collaborative ecoregion projects, such as this one in Arizona, are a step toward attaining consensus and consistency in ecoregion frameworks for the entire nation.

    Traditionally, pediatric chest diseases are evaluated with chest radiography. Due to advancements in technology, the use of sonography has broadened. It has now become an established radiation-free imaging tool that may supplement plain-film findings and, in certain cases, the first-line modality for evaluation of the pediatric chest. This pictorial essay will demonstrate the diagnostic potential of sonography, review a spectrum of pediatric chest conditions, and discuss their imaging features and clinical importance.

    Acute aortic syndrome is a group of life-threatening diseases of the thoracic aorta that usually present to the emergency department. It includes aortic dissection, aortic intramural hematoma, and penetrating aortic ulcer. Rare aortic pathologies of aorto-esophageal fistula and mycotic aneurysm may also be included in this list. All these conditions require urgent treatment with complex clinical care and management. Most patients who present with chest pain are evaluated with a chest radiograph in the emergency department. It is important that maximum diagnostic information is extracted from the chest radiograph as certain signs on the chest radiograph are extremely useful in pointing towards the diagnosis of acute aortic syndrome.

    Acute chest pain is a frequent consultation reason in general practice as well as in emergency departments. With the help of history, physical examination, ECG, laboratory and newly developed risk scores, potentially life-threatening diseases and high-risk patients may be detected and treated early, quickly and cost-effectively. New biomarkers and their combination with risk scores can increase the negative predictive value to exclude certain diseases. PMID:26886697

  17. The stove-in chest: a complex flail chest injury.

    PubMed

    Bloomer, Roger; Willett, Keith; Pallister, Ian

    2004-05-01

    The stove-in chest is a rare form of flail chest in which there is collapse of a segment of the chest wall, associated with a high immediate mortality. A 65-year-old male pedestrian was admitted with severe chest pain and dyspnoea, after being struck by a car. The initial chest radiograph demonstrated multiple right-sided rib fractures and pulmonary contusion. His gas exchange was good, and after pain relief via an epidural catheter was achieved, an intercostal drain was inserted into the right hemi-thorax. Clinically apparent deformation of the chest then occurred. A further chest radiograph confirmed the stove-in chest. The patient remained well initially, but on day 5 he deteriorated precipitously with respiratory failure, and signs of systemic sepsis. He died despite maximal ventilatory and inotropic support on the Intensive Care Unit (ICU). Post-mortem examination demonstrated congested, oedematous lungs with a right-sided empyema. The management of complex flail chest injuries requires treatment to be tailored to the individual patient. Early ventilatory support, despite good gas exchange, may have closed down the pleural space prevented the empyema. Prophylactic ventilation and possibly surgical stabilisation of the chest wall should be considered early in the course of admission, even when the conventional parameters to indicate ventilation are not met.

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

    B.1 Development of a Proximity Labeling Method to Identify the Protein Targets of Bioactive Small Molecules Zachary Hill, Min Zhuang, James Wells University of California, San Francisco, CA, USA Identifying the direct protein targets of a bioactive small molecule gives insight into the compound's mechanism of action, its efficacy, and possible toxicity. Target identification is becoming an increasingly important part of the drug- development process. However, given the transient and heterogeneous nature of interactions between small molecules and proteins, this step is often difficult, greatly slowing the development of new therapeutics. For this reason, new methods to rapidly identify the direct protein targets of bioactive small molecules are of great importance. Enrichment strategies coupled with quantitative mass spectrometry have shown great promise in target identification. Here we will present our progress toward developing an engineered enzymatic tagging method that enables specific labeling and enrichment of protein targets from complex lysates. This method couples the binding of a small molecule to a proximity-based labeling event. Labeled target proteins are enriched and subsequently identified using quantitative LC-MS/MS. We will discuss several variations of this method, and highlight our progress towards applying proximity labeling to small-molecule target identification and validation.

    provided information on regulation at a proteoform level that was not evident on a global quantification level. Of particular interest were the observations that NS1 appears to directly suppress the activation of NF-κB1 and to promote the survival of pro-apoptotic proteins within the infected cell. Furthermore, it was evident that hRSV has tactics to suppress the innate antiviral responses of the infected cell independently of NS1 and/or NS2. The strengths and weaknesses of these workflows will be discussed along with how specific observations provide a better understanding of how hRSV subverts host cell antiviral pathways. C.4 Improved Peak Detection and Deconvolution of Native Protein Complex Electrospray Mass Spectra Jonathan Lu, Michael Trnka, Shenheng Guan, A.L. Burlingame University of California, San Francisco, San Francisco, CA, USA Native electrospray-ionization mass spectrometry (native MS) measures biomolecules under conditions which preserve many aspects of protein secondary, tertiary, and quaternary structure in addition to primary structure and hence enables the measurement of large protein assemblies. However, spectra derived from these assemblies are often obscured by noise and peak overlap. The latter is especially critical because 1) higher mass protein complexes exhibit much broader ion signals than the instrumentally imposed limits of resolution due to incomplete desolvation and 2) one mass spectrum may contain many different components. The resulting peak overlap presents a great challenge towards extracting the true signals of underlying peaks. Additionally, wrong charge state assignment is a common problem. Here, we describe PeakSeeker, a comprehensive algorithm to handle the peak detection, peak overlap, and charge state assignment problems. We demonstrate that this software effectively deconvolutes heterogeneous native mass spectra that were inscrutable to previous algorithms. Existing algorithms for deconvolving overlapping peaks were

    2014-01-01

    We describe a case of a 42-year-old man who presented to the emergency department with severe left-sided chest pain and chest tenderness of 1-day duration. The pain was episodic and was aggravated by any chest wall movement. His initial blood tests and ECG were suggestive of acute coronary syndrome (ACS). However, his pattern of pain, lack of response to opiates, raised creatine kinase and signs of pleurisy on chest radiograph raised a suspicion of an alternative diagnosis. The patient showed a dramatic response in pain relief to non-steroidal anti-inflammatory medication. He was suspected to have chest wall myositis with pleural involvement in the form of pleurodynia. His serology test was positive for coxsackie virus antibodies. We will discuss in this case report the pathognomonic features, diagnosis and treatment of a rare infectious condition known as Bornholm disease. PMID:25312897

    Poster sessions are effective communication tools common at scientific meetings. The adaptations of poster sessions to the classroom have been reported to be effective evaluation and learning tools in chemistry and other disciplines. However, poster sessions have never been used to replace a standard hourly exam. We report here the use of a poster session as an oral examination in our introductory Integrated Chemistry/Physics/Mathematics course for entering freshmen. The poster exam replaces one traditional, in-class written examination, providing an alternate method of student assessment. Students' communication and organizational skills, their depth of knowledge of a particular topic, and their conceptual understanding of the topic are probed by the poster exam. Students report that the poster exam is more enjoyable and a more effective learning tool than traditional exams.

    A chest tube is a flexible plastic tube that is inserted through the chest wall and into the pleural space or mediastinum. It is used to remove air in the case of pneumothorax or fluid such as in the case of pleural effusion, blood, chyle, or pus when empyema occurs from the intrathoracic space. It is also known as a Bülau drain or an intercostal catheter. Insertion of chest tubes is widely performed by radiologists, pulmonary physicians and thoracic surgeons. Large catheters or small catheters are used based on each situation that the medical doctor encounters. In the current review we will focus on the chest drain systems that are in use. PMID:25815304

    An injury to the left ventricle after a chest tube insertion is a rare but lethal phenomenon that is likely to occur if precautions are not seriously addressed. We present a 15-year-old girl who was diagnosed a left empyema thoracis. An attempt to place a chest drain in this young girl was almost fatal. A left ventricular repair together with thoracotomy and decortication were successful. This case emphasizes the rarity of this lethal complication and the importance of the correct technique for chest tube insertion.

    Acute chest pain with very elevated troponin level and abnormal EKG in adult population is considered sine qua non to acute coronary syndrome (ACS) unless proved otherwise. Similar presentation in adolescent population is seen less often but raises suspicion for ACS. Most common etiology for chest pain with cardiac enzyme elevation in adolescent population is usually viral myopericarditis. The adolescent population presenting with chest pain and elevated cardiac enzymes should be carefully evaluated for ACS and other etiologies including myocarditis, myopericarditis, pulmonary embolism, acute rheumatic fever, and trauma. We report one Japanese adolescent male with mycoplasma pneumoniae myocarditis who presented to the ER with chest pain, elevated cardiac enzymes, and abnormal EKG. PMID:25202456

    Chest pain is a very common symptom and can be of cardiac or non-cardiac origin. It accounts for approximately 5.5 million annual emergency room visits in the United States, according to 2011 CDC data. Penetrating atherosclerotic aortic ulcer (PAU), an uncommon condition, is also a potential cause of chest pain. We here report the case of a 65-year-old woman who presented with atypical chest and back pain. The pain persisted for 4 weeks necessitating two emergency room visits. Initial tests were non-significant including cardiac troponins, an electrocardiogram (EKG), and a chest X-ray on her first visit. Upon her second visit, she underwent a computed tomography angiogram of chest with contrast which revealed a PAU with an intramural hematoma in descending aorta. The PAU was finally diagnosed with an exclusion of other chest pain causes. She was treated non-surgically with a blood pressure control strategy and pain management. After a 2-month period of smoking cessation and following the achievement of a controlled blood pressure, she felt well without chest pain. PMID:27406453

Several of the posters dealt with the pretreatment of cellulosic materials, and enzyme production/characterization, while a good number of papers displayed research efforts on bioremediation, photosynthesis, production of various useful chemicals from biomass by bioprocessing, and on other miscellaneous subjects. One of the papers treated a very interesting topic of cellulose-cellulase complexes. Many of the poster papers are included in this volume, and a synopsis of all the poster/papers presented is the subject of this article.

  10. Chest radiography in acute aortic syndrome: pearls and pitfalls.

    Acute aortic syndrome is a group of life-threatening diseases of the thoracic aorta that usually present to the emergency department. It includes aortic dissection, aortic intramural hematoma, and penetrating aortic ulcer. Rare aortic pathologies of aorto-esophageal fistula and mycotic aneurysm may also be included in this list. All these conditions require urgent treatment with complex clinical care and management. Most patients who present with chest pain are evaluated with a chest radiograph in the emergency department. It is important that maximum diagnostic information is extracted from the chest radiograph as certain signs on the chest radiograph are extremely useful in pointing towards the diagnosis of acute aortic syndrome.

    2016-01-01

    Angiolipoma is a rare variant of lipoma. Infiltrating chest wall angiolipoma usually presents as painful subcutaneous lesions. There are only a handful of cases reported in the literature. Malignancy is suspected in the differential diagnosis, and hence a tissue diagnosis is needed to rule out an underlying malignancy. Symptomatic infiltrating angiolipoma warrants surgical excision. We report a case of an infiltrating angiolipoma of the chest wall, which was successfully treated with surgical excision. PMID:26724328

    This case represents an individual who develops chest pain in a rehabilitation setting. It provides a description of possible assessments and investigations to screen for cardiovascular health. A thorough history and investigation can present a challenge in determining a definite diagnosis. Chiropractors who encounter patients in a rehabilitation program that develop chest pain must address the cardiac versus non-cardiac nature of the condition.

    The Royal Society of Chemistry held, to our knowledge, the world's first Twitter conference at 9am on February 5 (th), 2015. The conference was a Twitter-only conference, allowing researchers to upload academic posters as tweets, replacing a physical meeting. This paper reports the details of the event and discusses the outcomes, such as the potential for the use of social media to enhance scientific communication at conferences. In particular, the present work argues that social media outlets such as Twitter broaden audiences, speed up communication, and force clearer and more concise descriptions of a researcher's work. The benefits of poster presentations are also discussed in terms of potential knowledge exchange and networking. This paper serves as a proof-of-concept approach for improving both the public opinion of the poster, and the enhancement of the poster through an innovative online format that some may feel more comfortable with, compared to face-to-face communication.

    2014-01-01

    Although the initial diagnosis and follow-up of pleuropulmonary disease are normally done with plain chest films and the gold standard for chest disease is computed tomography, diverse studies have established the usefulness of chest ultrasonography in the diagnosis of different pleuropulmonary diseases like pleural effusion and lung consolidation, among others. In this article, we show the different ultrasonographic patterns for pleuropulmonary disease. The availability of ultrasonography in different areas (ICU, recovery areas) makes this technique especially important for critical patients because it obviates the need to transfer the patient. Moreover, ultrasonography is noninvasive and easy to repeat. On the other hand, it enables the direct visualization of pleuropulmonary disease that is necessary for interventional procedures.

    Five chest x-ray referral criteria statements have been developed and unanimously endorsed by a panel of physicians convened as part of a major voluntary cooperative effort between FDA's National Center for Devices and Radiological Health (NCDRH) and the medical professional community. The referral criteria statements include recommendations concerning the following applications of chest x-ray screening: mandated routine chest x-ray screening examinations, routine prenatal chest x-ray examinations, routine hospital admission chest x-ray examinations, chest x-ray examinations for tuberculosis detection and control, and routine chest x-ray examinations for occupational medicine. The complete text of the five referral criterial statements plus a brief discussion of the rationale for the development of each statement is presented.

    A 65-year-old man was evaluated for chronic chest pain that had been present for 8 years after placement of a dual-chamber implantable cardioverter-defibrillator to treat inducible ventricular tachycardia. Previous coronary angiography had revealed nonobstructive coronary artery disease and a left ventricular ejection fraction of 0.45 to 0.50, consistent with mild idiopathic nonischemic cardiomyopathy. Evaluation with chest radiography and transthoracic echocardiography showed the implantable cardioverter-defibrillator lead to be embedded within the right ventricle at the moderator band, which had mild calcification. Treatment included extraction of the dual-coil lead and placement of a new single-coil right ventricular lead at the mid septum. The patient had complete relief of symptoms after the procedure. This case shows that chest pain can be associated with the placement of a right ventricular implantable cardioverter-defibrillator lead in the moderator band and that symptomatic relief can occur after percutaneous lead extraction and the implantation of a new right ventricular lead to the mid septal region.

    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.

  3. Drupal as the platform of choice for the Skolr digital meeting poster service

    2011-12-01

    In the Winter of 2011, a small team received funding from the Alfred P. Sloan Foundation to build a pilot digital science meeting poster service (working name: Skolr). Skolr was successfully tested at the summer ESIP Federation meeting in Santa Fe. This talk will outline the issues for building out this service within Drupal. The use of Drupal as the framework/platform for Skolr is expected to facilitate the rapid development of the code base, an ability to then develop a mobile device application for meetings, and improved data-mining and searching. Each year in the USA (and elsewhere), professional academic societies host academic meetings where they provide for a poster session. Collectively, it is not difficult to imagine upwards of a quarter-million posters created, displayed, and discarded in a single year in the U.S. The Skolr service does not propose to replace the current poster activity with a digital activity, the direct person-to-person conversational aspects of these events remain worthwhile. When fully built, Skolr promises to enhance current poster session activities at academic meetings in several ways. For the poster presenter, Skolr offers the following opportunities: 1. Easy upload into an archive where the poster can be viewed by researchers across the globe. 2. Support for a wide range of metadata to improve search-ability. 3. Search and browse capabilities, combined with ratings and other user-generated value added capabilities (tagging and commenting). 4. The poster remains visible and findable for as long as the presenter wishes. 5. The presenter's profile and other information becomes available to those who view her poster, increasing the networking potential. 6. The presenter can activate their own RSS feeds to view similar posters from meetings across the planet and over years. For the meeting host organization, Skolr offers the following opportunities: 1. Social networking for meeting attendees/organizataion members. 2. Poster session

    The DEVELOP National Program addresses environmental and public policy issues through interdisciplinary research projects that apply the lens of NASA Earth observations to community concerns around the globe. Part of NASA's Applied Sciences' Capacity Building Program, DEVELOP bridges the gap between NASA Earth Science and society, building capacity in both participants and partner organizations to better prepare them to handle the challenges that face our society and future generations. Teams of DEVELOP participants partner with decision makers to conduct rapid feasibility projects that highlight fresh applications of NASA's suite of Earth observing sensors, cultivate advanced skills, and increase understanding of NASA Earth Science data and technology. Part of this process involves the creation of short introductory videos that demonstrate the environmental concerns, project methodologies and results, and an overview of how this work will impact decision makers. These videos are presented to the public three times a year in 'virtual poster sessions' (VPS) that provide an interactive way for individuals from around the globe to access the research, understand the capabilities and applications of NASA's Earth science datasets, and interact with the participants through blogging and dialogue sessions. Virtual poster sessions have allowed DEVELOP to introduce NASA's Earth science assets to thousands of viewers around the world. For instance, one fall VPS had over 5,000 visitors from 89 different countries during the two week session. This presentation will discuss lessons learned and statistics related to the series of nine virtual poster sessions that DEVELOP has conducted 2011-2013.

    Background and Objectives A cardiologist's evaluation of psychiatric symptoms in patients with chest pain is rare. This study aimed to determine the psychiatric characteristics of patients with and without coronary artery disease (CAD) and explore their relationship with the intensity of chest pain. Subjects and Methods Out of 139 consecutive patients referred to the cardiology outpatient department, 31 with atypical chest pain (heartburn, acid regurgitation, dyspnea, and palpitation) were excluded and 108 were enrolled for the present study. The enrolled patients underwent complete numerical rating scale of chest pain and the symptom checklist for minor psychiatric disorders at the time of first outpatient visit. The non-CAD group consisted of patients with a normal stress test, coronary computed tomography angiogram, or coronary angiogram, and the CAD group included those with an abnormal coronary angiogram. Results Nineteen patients (17.6%) were diagnosed with CAD. No differences in the psychiatric characteristics were observed between the groups. "Feeling tense", "self-reproach", and "trouble falling asleep" were more frequently observed in the non-CAD (p=0.007; p=0.046; p=0.044) group. In a multiple linear regression analysis with a stepwise selection, somatization without chest pain in the non-CAD group and hypochondriasis in the CAD group were linearly associated with the intensity of chest pain (β=0.108, R2=0.092, p=0.004; β= -0.525, R2=0.290, p=0.010). Conclusion No differences in psychiatric characteristics were observed between the groups. The intensity of chest pain was linearly associated with somatization without chest pain in the non-CAD group and inversely linearly associated with hypochondriasis in the CAD group. PMID:27014347

    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.

  9. The Use of Poster Sessions as a Tool to Integrate Concepts in Introduction to Environmental Science Classes

    For the past year we have required students within our Introduction to Environmental Science classes to present a poster during the final week of class. The course has no science or math prerequisites and serves a variety of students including majors in elementary education (70%) and environmental science (10%) and has an enrollment of around 60-80 students (enrollment currently limited by availability of classroom space). We have found the poster session to be an excellent avenue for students from diverse backgrounds to integrate concepts learned in the course and apply them to their chosen major. For example, majors in elementary education are encouraged to develop lessons plans or a hands on activity they can later use within their elementary classroom. All posters must be connected in some way to environmental issues in the El Paso/Juarez border community. In order to avoid last minute work on presentations, the students are required to select topics, search for initial references, and write abstracts for their posters as intermediate steps during the last 2 months of the course. Posters are presented in a special poster session where students rotate between roles as presenters and evaluators. Post-course assessments have shown that most students find the poster session helpful in learning to apply course concepts to situations outside of environmental science, especially within their chosen field of study. The major drawbacks to the poster format have been developing a consistent method to grade posters as well as the actual process of grading posters during the last week of classes.

  10. The Poster: A Petrologic Exercise For The Resource-Challenged

    Flood, T. P.

    2003-12-01

    The scientific poster is a common format for transmitting information and can be used as a petrologic exercise that may be particularly beneficial for those programs with limited resources. For example, the Saint Norbert College geology program was founded in 1987 and a traditional geology major established in 1994. We have high quality petrographic microscopes and excellent on-campus computing resources but otherwise lack common facilities such as a rock preparation room and instrumentation for obtaining research quality geochemical data such as XRF or SEM. The petrology poster exercise is designed to mimic the formative stages of a research project from fieldwork through geochemical analysis. A background literature search on a regional rock assemblage, usually suggested by the instructor, is conducted by the students. A specific petrologic aspect, such as the troctolitic portion of the Duluth Complex, is selected for investigation. Fieldwork consists of detailed outcrop and handsample descriptions, with approximately ten samples collected for thin section analysis. Geochemical data is culled from the literature by the instructor and computer modeled by the students using standard petrologic modeling programs such as IGPET. Having characterized the rock in detail, the students make interpretations of their data and more importantly, formulate research questions for future investigation. The final poster summarizes a student's work and is presented to their peers for critique. The goal of this semester-long exercise is to provide a near-professional research experience to the students for limited costs (i.e. site field trip and professional preparation of the thin sections). Additional benefits include: in-depth instruction related to writing an abstract, enhanced computer graphic skills related to poster construction, and a final product that makes an excellent springboard to a senior thesis.

Chits and EFNs and are accessible through the Mission Control Center - Houston (MCC-H) Gateway. Chits are the official means of documenting questions and answers, technical direction, real-time changes to Flight Rules (FR) and procedures, request for analysis, etc. between various consoles concerning on-orbit operations. EFNs are documents used by the Flight Control Team (FCT) to communicate precise details between console positions and manage real time changes to FR and Systems Operation Data File (SODF) procedures. On GMT 2013/345 the External Active Thermal Control System (EATCS) on the Columbus (COL) Moderate Temperature Loop (MTL) Interface Heat Exchanger (IFHX) shut down due to low temperatures. Over the next couple of days, the core temperature of COL MT IFHX dropped due to the failure of the Flow Control Valve (FCV). After the temperature drop was discovered, heaters were turned on to bring the temperatures back to nominal. After the incident occurred, a possible freeze threat was discovered that could have ruptured the heat exchanger. The COL MT IFHX rupturing would be considered a catastrophic failure and potentially result in a loss of the vehicle and/or the lives of the International Space Station (ISS) crew members

    The poster as a medium of communication serves to transmit a message by means of a graphical synthesis. It elicits attention by its originality, contrast, and focus on the center of interest. The poster is effective if the images and slogans can be identified easily. Its visual attractiveness is also essential. The understanding of the message is the function of the cultural characteristics of the public with symbols, metaphors, gestures, and detailed description. The appeal of the message allows the public to accept it on sensorial, emotional, social, intellectual, and economical levels. Adverse motivations should not be confused with the positive appeal (prejudice, preconceived ideas, and bias). Confusion and ambiguity can carry conflicting messages, therefore negative examples should be avoided. The force of the message targets the memory carrying conviction and calling to action. The target group and objective must be defined as to age, occupation, location, and sex. The message also has to be defined precisely for the target audience. It is in the analysis of the context whereby the poster is received as to notions of the target topic, alternative attitudes relative to the promotion of the message, obstacles that are encountered in the mentality of the target, and cultural characteristics of the target audience. The text of the slogan must be given before drawing the poster. The designing of the poster should be creative with association of ideas, metaphors and symbols, descriptive images, fusion of symbolic and descriptive forms, humor, the fusion of graphics with letters, and the fusion of letters with images. Completed forms of the poster use illustration, photography, typography, calligraphy, and photo montage. PMID:12281468

    2016-06-01

    Blunt chest traumatic coronary artery dissection is an uncommon cause of atherosclerotic and non-atherosclerotic Acute Myocardial Infarction (AMI). Injuries of the coronary artery after blunt chest trauma are caused by different mechanisms such as vascular spasm, dissection and intimal tear or rupture of an existing thrombus formation. Chest pain might be masked by other injuries in patients with multiple traumas in car accident. Present case report is on a 37-year-old male without any specific past medical history who reported to the emergency department of a hospital with chest discomfort and was discharged with the impression of chest wall pain. After three days he experienced severe chest pain and he was admitted with the impression of acute coronary syndrome and underwent coronary angiography which showed Left Anterior Descending (LAD) artery dissection. The possibility of injury of the coronary artery should be kept in mind after blunt trauma to the chest. This condition is sometimes underdiagnosed. Its diagnosis may be difficult because chest pain can be interpreted as being secondary to chest wall contusion or it may be overshadowed by other injuries. Coronary dissection diagnosis after chest trauma requires clinical suspicion and systematic evaluation. Electrocardiography (ECG) should be done for every patient with thoracic trauma as the clinical findings may be misleading. PMID:27504338

    Background Chest pain is a common clinical syndrome. However, there is a paucity of African studies describing the causes, prevalence, aetiology, and disposition of patients with chest pain presenting in the emergency department (ED). Aim The aim of this retrospective descriptive study was to determine the prevalence, causes, demographics, and disposition of all adult patients with the main complaint of chest pain presenting at the ED of a regional hospital in South Africa. Methods Records of all patients 18 years and older presenting with the complaint of chest pain from 1 December 2011 through 10 April 2012 were assessed. A data collection sheet capturing patient demographics and disposition from the ED was used. The diagnosis was subdivided into groups: cardiovascular, respiratory, gastrointestinal, musculoskeletal, psychiatric/psychogenic, other, and unknown. Results Of the 312 patients presenting with chest pain, 210 patient files were retrieved. The prevalence of non-traumatic chest pain was 1.66%. Respiratory disease was the most common cause (36.19%), with pneumonia the most common diagnosis (24.40%). Logistic regression showed diagnoses of acute cardiovascular disease or respiratory disease, older age, and transport by ambulance as being associated with admission. Conclusion The main cause of acute chest pain was found to be respiratory disease, followed by musculoskeletal disorders. In the African context, the aetiology of acute chest pain differs from that in first world countries. Health workers should therefore pay special attention to respiratory conditions during diagnosis and management in African patients with acute chest pain. PMID:27380782

    Chest radiographs frequently underestimate the severity and extent of chest trauma and, in some cases, fail to detect the presence of injury. CT is more sensitive than chest radiography in the detection of pulmonary, pleural, and osseous abnormalities in the patient who has chest trauma. With the advent of multidetector CT (MDCT), high-quality multiplanar reformations are obtained easily and add to the diagnostic capabilities of MDCT. This article reviews the radiographic and CT findings of chest wall, pleural, and pulmonary injuries that are seen in the patient who has experienced blunt thoracic trauma.

    Objectives To present our experience of reconstructing wide defects with porously titanium mesh after radical resection of malignant chest wall tumors. Methods A retrospective review of surgical reconstruction for large chest wall resections with titanium mesh was conducted from January 2009 to August 2014 in Shanghai Chest Hospital. Results A total of 27 patients underwent major chest wall reconstructions with titanium mesh, following oncological resections. Chest wall sarcomas were the most frequent (63.0%). The mean tumor size was 72.4 (range, 36-140) cm2. The average size of the applied porously titanium mesh was 140.9 (range, 80-225) cm2. Mean postoperative length of stay was 7.1 (range, 4-14) days. There were no perioperative mortalities. Four (14.8%) patients experienced treatable complications. All had a resection of at least 3 ribs (median 3, mean 3.5 ribs). A total of 22 patients underwent ribs without sternal resections, and five patients underwent partial sternal resections with adjacent costal cartilage. Anterior chest wall resections were performed in 13 patients while lateral chest wall resections were performed in 9 patients. Three patients had extended resections beyond the chest wall in patients with primary chest wall malignancies, including two with wedge resections of lung and one with partial resection of pericardium. No patient was lost to follow-up. Mean follow-up was 30.7 months. Neither chest wall instability nor wound infection/necrosis was observed. Of these, 23 patients (85.2%) were alive at the last follow-up. Local recurrence was detected in three cases. The 5-year disease-free and overall survivals of primary chest tumors were 72.1% and 80.8%, respectively. Conclusions Our results showed that chest wall reconstruction utilizing synthetic titanium meshes following extensive resections of the chest wall malignant tumors allowed adequate resection size, with acceptable complications and survival benefits.

    The present report describes a case involving a 57-year-old HIV-positive man who presented with acute retrosternal chest pain accompanied by 24 h of fever. Septic arthritis of the manubriosternal joint was diagnosed based on magnetic resonance imaging findings in addition to Staphylococcus aureus bacteremia. To the authors' knowledge, the present case is only the 12th reported case of manubriosternal septic arthritis, and the first in an HIV-positive patient. Early diagnosis and treatment can circumvent the need for surgical intervention. Based on the present case report and review of the literature, the authors summarize the epidemiology, appropriate imaging and suggestions for antibiotic therapy for this rare presentation.

    The clinical demand for a device to monitor blood pressure (BP) in ambulatory scenarios with minimal use of inflation cuffs is increasing. Based on the so-called pulse wave velocity (PWV) principle, this paper introduces and evaluates a novel concept of BP monitor that can be fully integrated within a chest sensor. After a preliminary calibration, the sensor provides nonocclusive beat-by-beat estimations of mean arterial pressure (MAP) by measuring the pulse transit time (PTT) of arterial pressure pulses travelling from the ascending aorta toward the subcutaneous vasculature of the chest. In a cohort of 15 healthy male subjects, a total of 462 simultaneous readings consisting of reference MAP and chest PTT were acquired. Each subject was recorded at three different days: D, D+3, and D+14. Overall, the implemented protocol induced MAP values to range from 80 ± 6 mmHg in baseline, to 107 ± 9 mmHg during isometric handgrip maneuvers. Agreement between reference and chest-sensor MAP values was tested by using intraclass correlation coefficient (ICC = 0.78) and Bland-Altman analysis (mean error = 0.7 mmHg, standard deviation = 5.1 mmHg). The cumulative percentage of MAP values provided by the chest sensor falling within a range of ±5 mmHg compared to reference MAP readings was of 70%, within ±10 mmHg was of 91%, and within ±15 mmHg was of 98%. These results point at the fact that the chest sensor complies with the British Hypertension Society requirements of Grade A BP monitors, when applied to MAP readings. Grade A performance was maintained even two weeks after having performed the initial subject-dependent calibration. In conclusion, this paper introduces a sensor and a calibration strategy to perform MAP measurements at the chest. The encouraging performance of the presented technique paves the way toward an ambulatory compliant, continuous, and nonocclusive BP monitoring system. PMID:23864147

    This article aims to provide a concise, structured approach to the child with chest pain. Chest pain is a common presenting symptom in children but, unlike in adults, the cause is rarely cardiac. We review the main causes of chest pain in children and discuss the important features that may alert those assessing paediatric chest pain to serious underlying pathology. In the vast majority of cases, reassurance is all that is required and a thorough initial consultation can exclude rare, serious disease and provide vital reassurance to children and families.

    In the last year, 12 patients have undergone extensive chest wall resection. Eight patients had recurrent cancer after prior resection and irradiation with an average defect of 160 square centimeters, usually including ribs and a portion of the sternum; four had radionecrosis of soft tissue and/or bone. Methods of reconstruction included latissimus dorsi musculocutaneous (MC) flap (five patients), pectoralis major MC flap (seven patients), and omental flap and skin graft (one patient). The donor site was usually closed primarily. All flaps survived providing good wound coverage. The only complication was partial loss of a latissimus dorsi MC flap related to an infected wound; this reconstruction was salvaged with a pectoralis major MC flap. The hospital stay ranged from 10-25 days with a median stay of 11 days. Use of the MC flap is a valuable tool which can be used to significantly decrease morbidity, hospital stay, and patient discomfort related to the difficult problem of chest wall reconstruction after radiation therapy.

    Extrapleural solitary fibrous tumours (SFTs) are rare tumours characterized by patternless spindle cells with haemangiopericytoma-like vascular spaces. Previously the tumours have been classified as haemangiopericytoma, an entity that is now considered obsolete. We report a case of extrapleural SFT arising in the soft tissue of the chest wall. The patient was a 31-year-old Malay lady presenting with a mobile swelling of the right chest wall for more than five years. During excision the tumour was noted to be well-circumscribed and yellowish in colour, giving an impression of lipoma. Microscopically, the tumour had patternless architecture, characterized by hypocellular and hypercellular areas. It was composed of uniform, spindle-shaped cells displaying oval nuclei, inconspicuous nucleoli, pale cytoplasm and indistinct cell borders. The mitotic count was 2 per 10 HPF. Branching, medium-sized thin-walled blood vessels in a haemangiopericytomatous growth pattern, some with hyalinised wall were identified. The neoplastic cells were immunoreactive to CD99 and CD34 and were non-immunoreactive to Desmin, Smooth Muscle Actin, S100 protein and EMA. We elucidate the challenges in diagnosing this tumour in this unusual location.

    1990-07-01

    Although chest radiography is the most commonly performed radiographic examination and one of the most valuable and cost-effective studies in medicine it suffers from relatively high error rates in both missing pathology and false positive interpretations. Detectability of lung nodules and other structures in underpenetrated regions of the chest film can be improved by both exposure and optical compensation but current compensation systems require major capital cost or a significant change in normal clinical practice. A new optical compensation system called the " Intelligent X-Ray Illuminator" (IXI) automatically and virtually instantaneously generates a patient-specific optical unsharp mask that is projected directly on a radiograph. When a radiograph is placed on the IXI which looks much like a conventional viewbox it acquires a low-resolution electronic image of this film from which the film transmission is derived. The transmission information is inverted and blurred in an image processor to form an unsharp mask which is fed into a spatial light modulator (SLM) placed between a light source and the radiograph. The SLM tailors the viewbox luminance by decreasing illumination to underexposed (i. e. transmissive) areas of the radiograph presenting the observer with an optically unsharp-masked image. The IXI uses the original radiograph and will allow it to be viewed on demand with conventional (uniform illumination. Potentially the IXI could introduce the known beneficial aspects of optical unsharp masking into radiology at low capital

    A wide spectrum of thoracic tumors have known or suspected viral etiologies. Oncogenic viruses can be classified by the type of genomic material they contain. Neoplastic conditions found to have viral etiologies include post-transplant lymphoproliferative disease, lymphoid granulomatosis, Kaposi's sarcoma, Castleman's disease, recurrent respiratory papillomatosis, lung cancer, malignant mesothelioma, leukemia and lymphomas. Viruses involved in these conditions include Epstein-Barr virus, human herpes virus 8, human papillomavirus, Simian virus 40, human immunodeficiency virus, and Human T-lymphotropic virus. Imaging findings, epidemiology and mechanism of transmission for these diseases are reviewed in detail to gain a more thorough appreciation of disease pathophysiology for the chest radiologist.

    Automobile development is increasingly based on mathematical modeling. Accurate models of the human body are now available and serve to develop new means of protection. These models used to consist of rigid, articulated bodies but are now made of several million finite elements. They are now capable of predicting some risks of injury. To develop these models, sophisticated tests were conducted on human cadavers. For example, chest modeling started with material characterization and led to complete validation in the automobile environment. Model personalization, based on medical imaging, will permit studies of the behavior and tolerances of the entire population.

    Chest physical examination often includes performing chest percussion, which involves introducing sound stimulus to the chest wall and detecting an audible change. This approach relies on observations that underlying acoustic transmission, coupling, and resonance patterns can be altered by chest structure changes due to pathologies. More accurate detection and quantification of these acoustic alterations may provide further useful diagnostic information. To elucidate the physical processes involved, a realistic computer model of sound transmission in the chest is helpful. In the present study, a computational model was developed and validated by comparing its predictions with results from animal and human experiments which involved applying acoustic excitation to the anterior chest, while detecting skin vibrations at the posterior chest. To investigate the effect of pathology on sound transmission, the computational model was used to simulate the effects of pneumothorax on sounds introduced at the anterior chest and detected at the posterior. Model predictions and experimental results showed similar trends. The model also predicted wave patterns inside the chest, which may be used to assess results of elastography measurements. Future animal and human tests may expand the predictive power of the model to include acoustic behavior for a wider range of pulmonary conditions.

    This paper presents study of computer analysis of the 1980 ILO standard chest radiographs of pneumoconiosis. Algorithms developed for detection of individual small rounded and irregular opacities have been experimented and evaluated on these standard radiographs. The density, shape, and size distribution of the detected objects in the lung field, in spite of false positives, can be used as indicators for the beginning of pneumoconiosis. This approach is potentially useful in computer-assisted screening and early detection process where the annual chest radiograph of each worker is compared with his (her) own normal radiograph obtained previously.

    Chest radiographs that are correctly obtained and interpreted provide valuable diagnostic information. However, some radiographs are not taken at total lung capacity, and the appearance of the lungs on film may mimic certain lung disorders. Most common interpretive pitfalls in chest radiography can be avoided by physicians who are familiar with the film appearance of varying degrees of lung inflation, technical limitations of portable radiography, and common chest abnormalities. When further definition is necessary, additional projections should be obtained. Chest fluoroscopy and computed tomography can offer further clarification, if needed. PMID:2296566

    The significance of a history of heart failure (HF) in patients presenting with acute coronary syndromes and elevated cardiac markers is unclear. The authors performed an analysis of patients enrolled in the Internet Tracking Registry of Acute Coronary Syndromes (i*trACS). Cardiac marker measurement and cardiac catheterization were performed in 1174 patients. Of these, 116 (9.9%) had heart failure (HF). Coronary artery disease (CAD) was found in 61 (52.6%) patients in the HF group and 581 (54.9%) in the group without HF. In the non-HF cohort, positive markers occurred in 306 patients, in whom 217 (70.9%) had CAD at catheterization. In the HF subset, 24 patients had positive biomarkers and 15 (62.5%) had CAD. A history of HF did not lessen the likelihood of CAD as evidenced by angiography and does not diminish the utility of cardiac markers in diagnosing acute coronary syndromes.

    The Advanced Photon Source (APS), which is currently under construction as a national user facility at Argonne National Laboratory is a third-generation synchrotron x-ray source, one of only three in the world. It is expected to produce x-rays that are 10,000 times brighter than any currently produced elsewhere for use in research in a wide range of scientific areas. Users from industry, national laboratories, universities, and business will be able to come to the APS to conduct research either as members of Collaborative Access Teams (CATS) or as Independent Investigators. Principal users will be members of CATS, which will be building and operating all of the beamlines present in the first phase of APS beamline development. The first set of CATs has been selected through a competitive proposal process involving peer scientific review, thorough technical evaluation, and significant management oversight by the APS. This document is a compilation of posters presented at the Fifth Users Meeting for the Advanced Photon Source, held at Argonne National Laboratory on October 14--15, 1992.

    Solitary pulmonary nodule represents 0.2% of incidental findings in routine chest X-ray images. One of the main diagnoses includes lung cancer in which small-cell subtype has a poor survival rate. Recently, a new classification has been proposed including the very limited disease stage (VLD stage) or T1-T2N0M0 with better survival rate, specifically in those patients who are treated with surgery. However, current recommendations postulate that surgery remains controversial as a first-line treatment in this stage. We present the case of a 46-year-old female referred to our hospital with a preoperative diagnosis of a solitary pulmonary nodule. On initial approach, a biopsy revealed a small cell lung cancer. She received multimodal therapy with surgery, chemotherapy, and prophylactic cranial irradiation and is currently alive without recurrence on a 2-year follow-up. PMID:22345914

    Pleuritic pain, a sharp discomfort near the chest wall exacerbated by inspiration is associated with a number of pathologies. Pulmonary embolus and infection are two common causes but diagnosis can often be challenging, both for experienced physicians and trainees. The underlying anatomy and pathophysiology of such pain and the most common aetiologies are presented. Clinical symptoms and signs that may arise alongside pleuritic pain are then discussed, followed by an introduction to the diagnostic tools such as the Wells’ score and current guidelines that can help to select the most appropriate investigation(s). Management of pulmonary embolism and other common causes of pleuritic pain are also discussed and highlighted by a clinical vignette. PMID:22993751

    A series of 98 chest films was interpreted by two physicians on the basis of monitor display of the transmitted television signal representing the roentgenographic image. The transmission path was 14 miles long, and included one active repeater station. Receiver operating characteristic curves were drawn to compare interpretations rendered on television view of the image with classic, direct view interpretations of the same films. Performance in these two viewing modes was found to be quite similar. When films containing only hazy densities lacking internal structure or sharp margins, were removed from the sample, interpretation of the remaining films was essentially identical via the two modes. Since hazy densities are visible on retrospective examination, interpretation of roentgenograms at a distance via television appears to be a feasible route for delivery of radiologic services.

Coronary artery dissection culminating in acute myocardial infarction (AMI) is rare after blunt chest trauma. Here we report a case of a 37-year-old man who had an AMI secondary to coronary dissection resulting from blunt chest trauma after involvement in a physical fight. PMID:25246456

    The goal of the Information Presentation Directed Research Project (DRP) is to address design questions related to the presentation of information to the crew. In addition to addressing display design issues associated with information formatting, style, layout, and interaction, the Information Presentation DRP is also working toward understanding the effects of extreme environments encountered in space travel on information processing. Work is also in progress to refine human factors-based design tools, such as human performance modeling, that will supplement traditional design techniques and help ensure that optimal information design is accomplished in the most cost-efficient manner. The major areas of work, or subtasks, within the Information Presentation DRP for FY10 are: 1) Displays, 2) Controls, 3) Procedures and Fault Management, and 4) Human Performance Modeling. The poster will highlight completed and planned work for each subtask.

  17. An Innovative Model: Undergraduate Poster Sessions by Health Professional Majors as a Method for Communicating Chemistry in Context

    1997-09-01

    This paper develops the methods used to conduct poster sessions for undergraduate health professional majors. There are two main goals of the project. The first goal is to learn chemistry in the context of health professions, everyday activities and contemporary issues. The second goal is to continue to develop research and written and oral communication skills. The topics are chosen after a classroom discussion of organic chemistry. The students then attend a library instruction class for introduction to appropriate research tools. Students are also taught the mechanics of poster preparation. The sessions are presented during a laboratory class period and are open to the college and public at large. Evaluation criteria include comprehension of the chemistry, the level and accuracy of the discussion and the appropriateness of the poster design for information exchange, All levels of the college community are invited to participate and greatly contribute to the success of the poster sessions.

    Segmentation of individual ribs and other bone structures in chest CT images is important for anatomical analysis, as the segmented ribs may be used as a baseline reference for locating organs within a chest as well as for identification and measurement of any geometric abnormalities in the bone. In this paper we present a fully automated algorithm to segment the individual ribs from low-dose chest CT scans. The proposed algorithm consists of four main stages. First, all the high-intensity bone structure present in the scan is segmented. Second, the centerline of the spinal canal is identified using a distance transform of the bone segmentation. Then, the seed region for every rib is detected based on the identified centerline, and each rib is grown from the seed region and separated from the corresponding vertebra. This algorithm was evaluated using 115 low-dose chest CT scans from public databases with various slice thicknesses. The algorithm parameters were determined using 5 scans, and remaining 110 scans were used to evaluate the performance of the segmentation algorithm. The outcome of the algorithm was inspected by an author for the correctness of the segmentation. The results indicate that over 98% of the individual ribs were correctly segmented with the proposed algorithm.

    In the museum of medical history in Lund there are several wooden chests containing partly identical instruments apparently belonging to a midwife. The instruments dated from before 1900, e.g. lancets and horn cups for blood-letting, a pewter enema syringe, a wooden stethoscope, a "tobacco pipe" and glass bottles. The use of the tobacco pipe was first puzzling, but it appeared to be a breast reliver. What do we know about the date of the chests? One chest has belonged to Kjersti Nilsdotter, a midwife educated in Lund 1872-1873. Her certificate was in the chest. From Ronnie Hunt, Minnesota we have got information about another chest of the same type. That belonged to Nelly Gustafsson, a midwife educated in Lund probably about 1870. She emigrated to USA and was a practising midwife in Lindstrom, Minnesota from about 1900.

    A 32-year-old man was elbowed in the chest while fighting for a rebound in a recreational basketball game. He fell to the ground and his chest ached from the blow. Four days later he developed more severe chest pressure with dyspnea and came to the hospital. His chest wall was tender and his pulse slow, but the remainder of his physical examination was normal. Electrocardiogram showed sinus bradycardia, first-degree atrioventricular (AV) block, and occasional isorhythmic AV dissociation, but no ischemic ST-T changes. Cardiac troponin I rose to 1.74 ng/mL (normal <0.50). The patient therefore underwent coronary angiography, showing spiral dissection of the right coronary artery with extensive thrombus filling the distal portion of the vessel. Stenting was unsuccessful in restoring flow. This case highlights the potential dangers of blunt chest trauma in recreational sports and shows how angiography can distinguish myocardial contusion from coronary artery dissection.

    A quantitative computerized method which provides accurate discrimination between chest radiographs with positive findings of interstitial disease patterns and normal chest radiographs may increase the efficacy of radiologic screening of the chest and the utility of digital radiographic systems. This report is a comparison of fractal dimension measured in normal chest radiographs and in radiographs with abnormal lungs having reticular, nodular, reticulonodular and linear patterns of interstitial disease. Six regions of interest (ROI's) from each of 33 normal chest radiographs and 33 radiographs with positive findings of interstitial disease were studied. Results indicate that there is a statistically significant difference between the distribution of the fractal dimension in normal radiographs and radiographs where disease is present.

    Acute chest syndrome is a frequent cause of acute lung disease in children with sickle-cell disease. Asthma is common in children with sickle-cell disease and is associated with increased incidence of vaso-occlusive pain events, acute chest syndrome episodes, and earlier death. Risk factors for asthma exacerbation and an acute chest syndrome episode are similar, and both can present with shortness of breath, chest pain, cough, and wheezing. Despite overlapping risk factors and symptoms, an acute exacerbation of asthma or an episode of acute chest syndrome are two distinct entities that need disease-specific management strategies. Although understanding has increased about asthma as a comorbidity in sickle-cell disease and its effects on morbidity, substantial gaps remain in knowledge about best management. PMID:27353685

    The Virtual Poster Session (VPS) of the Association of Polar Early Career Scientists (APECS) was developed by early career scientists as an online tool for communicating and discussing science and research beyond the four walls of a conference venue. Poster sessions often are the backbone of a conference where especially early career scientists get a chance to communicate their research, discuss ideas, data, and scientific problems with their peers and senior scientists. There, they can hone their 'elevator pitch', discussion skills and presentation skills. APECS has taken the poster session one step further and created the VPS - the same idea but independent from conferences, travel, and location. All that is needed is a computer with internet access. Instead of letting their posters collect dust on the computer's hard drive, scientists can now upload them to the APECS website. There, others have the continuous opportunity to comment, give feedback and discuss the work. Currently, about 200 posters are accessible contributed by authors and co-authors from 34 countries. Since January 2010, researchers can discuss their poster with a broad international audience including fellow researchers, community members, potential colleagues and collaborators, policy makers and educators during monthly conference calls via an internet platform. Recordings of the calls are available online afterwards. Calls so far have included topical sessions on e.g. marine biology, glaciology, or social sciences, and interdisciplinary calls on Arctic sciences or polar research activities in a specific country, e.g. India or Romania. They attracted audiences of scientists at all career stages and from all continents, with on average about 15 persons participating per call. Online tools like the VPS open up new ways for creating collaborations and new research ideas and sharing different methodologies for future projects, pushing aside the boundaries of countries and nations, conferences

  11. Localized Fisher vector representation for pathology detection in chest radiographs

    2016-03-01

    In this work, we present a novel framework for automatic detection of abnormalities in chest radiographs. The representation model is based on the Fisher Vector encoding method. In the representation process, we encode each chest radiograph using a set of extracted local descriptors. These include localized texture features that address typical local texture abnormalities as well as spatial features. Using a Gaussian Mixture Model, a rich image descriptor is generated for each chest radiograph. An improved representation is obtained by selection of features that correspond to the relevant region of interest for each pathology. Categorization of the X-ray images is conducted using supervised learning and the SVM classifier. The proposed system was tested on a dataset of 636 chest radiographs taken from a real clinical environment. We measured the performance in terms of area (AUC) under the receiver operating characteristic (ROC) curve. Results show an AUC value of 0.878 for abnormal mediastinum detection, and AUC values of 0.827 and 0.817 for detection of right and left lung opacities, respectively. These results improve upon the state-of-the-art as compared with two alternative representation models.

  12. Outpatient diagnosis of acute chest pain in adults.

    2013-02-01

    Approximately 1 percent of primary care office visits are for chest pain, and 1.5 percent of these patients will have unstable angina or acute myocardial infarction. The initial goal in patients presenting with chest pain is to determine if the patient needs to be referred for further testing to rule in or out acute coronary syndrome and myocardial infarction. The physician should consider patient characteristics and risk factors to help determine initial risk. Twelve-lead electrocardiography is typically the test of choice when looking for ST segment changes, new-onset left bundle branch block, presence of Q waves, and new-onset T wave inversions. For persons in whom the suspicion for ischemia is lower, other diagnoses to consider include chest wall pain/costochondritis (localized pain reproducible by palpation), gastroesophageal reflux disease (burning retrosternal pain, acid regurgitation, and a sour or bitter taste in the mouth), and panic disorder/anxiety state. Other less common but important diagnostic considerations include pneumonia (fever, egophony, and dullness to percussion), heart failure, pulmonary embolism (consider using the Wells criteria), acute pericarditis, and acute thoracic aortic dissection (acute chest or back pain with a pulse differential in the upper extremities). Persons with a higher likelihood of acute coronary syndrome should be referred to the emergency department or hospital.

    The chest response of the human body has been studied for several load conditions, but is not well known in the case of steering wheel rim-to-chest impact in heavy goods vehicle frontal collisions. The aim of this study was to determine the response of the human chest in a set of simulated steering wheel impacts. PMHS tests were carried out and analysed. The steering wheel load pattern was represented by a rigid pendulum with a straight bar-shaped front. A crash test dummy chest calibration pendulum was utilised for comparison. In this study, a set of rigid bar impacts were directed at various heights of the chest, spanning approximately 120mm around the fourth intercostal space. The impact energy was set below a level estimated to cause rib fracture. The analysed results consist of responses, evaluated with respect to differences in the impacting shape and impact heights on compression and viscous criteria chest injury responses. The results showed that the bar impacts consistently produced lesser scaled chest compressions than the hub; the Middle bar responses were around 90% of the hub responses. A superior bar impact provided lesser chest compression; the average response was 86% of the Middle bar response. For inferior bar impacts, the chest compression response was 116% of the chest compression in the middle. The damping properties of the chest caused the compression to decrease in the high speed bar impacts to 88% of that in low speed impacts. From the analysis it could be concluded that the bar impact shape provides lower chest criteria responses compared to the hub. Further, the bar responses are dependent on the impact location of the chest. Inertial and viscous effects of the upper body affect the responses. The results can be used to assess the responses of human substitutes such as anthropomorphic test devices and finite element human body models, which will benefit the development process of heavy goods vehicle safety systems.

    PubMed

    2014-01-01

    When a patient complains of chest pain, the first priority is to establish whether the situation is life threatening. Life-threatening differential diagnoses that clinicians must consider include acute coronary syndrome, cardiac tamponade, pulmonary embolus, aortic dissection, and tension pneumothorax. Nonthreatening causes of chest pain that should be considered include spontaneous pneumothorax, pleural effusion, pneumonia, valvular diseases, gastric reflux, and costochondritis. The challenge for clinicians is not to be limited by "satisfaction of search" and fail to consider important differential diagnoses. The challenge, however, can be met by developing a systematic method to assess chest pain that will lead to the appropriate diagnosis and appropriate treatment plan.

    Routine radiographic chest examinations have been performed using a variety of techniques. Although chest radiography is one of the most commonly performed radiographic examinations, it is often difficult to obtain consistently good quality roentgenograms. This publication provides a simple guide and relatively easy solution to the many problems that radiologic technologists might encounter. The language is purposely relatively simple and care has been taken to avoid difficult mathematical and physical explanations. The intent is to provide an easily referrable text for those who may encounter difficulties in producing acceptable chest radiographs.

    The impact of major life events and daily hassles on atypical chest pain is unknown. The aim of the present study was to investigate the relationship of the occurrence and perception of major life events and daily hassles in atypical chest pain patients. Five groups of subjects were studied. They were healthy controls, atypical chest pain patients without motility/reflux changes, atypical chest pain patients with motility/reflux changes, dyspeptic patients, and patients with chronic obstructive airway disease/peptic ulcer/gallstone. A questionnaire concerning the occurrence and perception of major life events and daily hassles was administered to all five groups of subjects. Using analysis of variance, we found that atypical chest pain patients without underlying motility/reflux changes had significantly higher scores of negative life events and total life events than healthy controls, atypical chest pain patients with underlying motility/reflux changes, and patients with chronic obstructive airway disease/peptic ulcer/gallstone. There were no significant differences between atypical chest pain patients without underlying motility/reflux changes and patients with dyspepsia in terms of the number of negative life events, negative scores, number of positive life events, positive scores, and total life events. Discriminate analysis identified five of the 47 major life events (major changes in sleeping habits, change in work situation, major changes in financial status, retirement, and suffering from severe illness or injury) to be useful for discriminating atypical chest pain patients without underlying motility/reflux changes from the healthy controls and from atypical chest pain patients with underlying motility/reflux changes. The overall correct classification rate was 81.8%. In conclusion, psychological factors, such as perception of negative life events and occurrence and perception of daily hassles, may play a role in the pathogenesis of atypical chest pain.

    The Royal Society of Chemistry held, to our knowledge, the world’s first Twitter conference at 9am on February 5 th, 2015. The conference was a Twitter-only conference, allowing researchers to upload academic posters as tweets, replacing a physical meeting. This paper reports the details of the event and discusses the outcomes, such as the potential for the use of social media to enhance scientific communication at conferences. In particular, the present work argues that social media outlets such as Twitter broaden audiences, speed up communication, and force clearer and more concise descriptions of a researcher’s work. The benefits of poster presentations are also discussed in terms of potential knowledge exchange and networking. This paper serves as a proof-of-concept approach for improving both the public opinion of the poster, and the enhancement of the poster through an innovative online format that some may feel more comfortable with, compared to face-to-face communication.

A mass, 7 cm in size, with destruction of the right 4th rib was found on chest computed tomography. A F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) corresponding to the lesion showed an abnormal accumulation of FDG with the standardized uptake value(SUV) max=16.19. A malignant tumor of the chest wall origin was suspected and the tumor was resected with the 3th, 4th, and 5th ribs. Histologically, the tumor was diagnosed as dedifferentiated chondrosarcoma. He died of local recurrence about 5 months after the operation. PMID:27476566

    Over the last two years, several entities - from banks to credit unions to solar finance companies -have rolled out distributed solar-specific loan programs in the United States. These solar-specific loans are a distinct loan in that the underwriting, loan terms, lender security interest, and other programmatic aspects are designed exclusively for the financing of solar installations. Until recently, loan financing for distributed solar installations was largely through home equity loans, commercial loans, and other standardized loan products available to homeowners and businesses for general expenditures. However, as the U.S. solar market matures, so too are its financing options, and solar-specific loans stand to gain market share. This poster was presented at the Solar Power International conference in Las Vegas, NV in October 2014.

  6. Effects of Changing Atmospheric Conditions on Wind Turbine Performance (Poster)

    SciTech Connect

    Clifton, A.

    2012-12-01

    Multi-megawatt, utility-scale wind turbines operate in turbulent and dynamic winds that impact turbine performance in ways that are gradually becoming better understood. This poster presents a study made using a turbulent flow field simulator (TurbSim) and a Turbine aeroelastic simulator (FAST) of the response of a generic 1.5 MW wind turbine to changing inflow. The turbine power output is found to be most sensitive to wind speed and turbulence intensity, but the relationship depends on the wind speed with respect to the turbine's rated wind speed. Shear is found to be poorly correlated to power. A machine learning method called 'regression trees' is used to create a simple model of turbine performance that could be used as part of the wind resource assessment process. This study has used simple flow fields and should be extended to more complex flows, and validated with field observations.

    Non cardiac chest pain (NCCP) are recurrent angina pectoris like pain without evidence of coronary heart diesease in conventional diagnostic evaluation. The prevalence of NCCP is up to 70% and may be detected in this order at all levels of the medical health care system (general practitioner, emergency department, chest pain unit, coronary care). Reduction of quality of life in NCCP is comparable, partially even higher compared to cardiac chest pain.

    Since 1970 we have stabilized the ribs to correct paradoxical movement of the chest wall in chest injuries, using an original technique, in order to avoid as far as possible the need for long-term chest wall stabilization by intermittent positive pressure respiration (IPPR). The technical details of surgical stabilization are described, and the different types of stainless steel struts are shown. Type I was originally used either as an intramedullary nail or as an external brace. Types II and III were designed for external fixation of the strut to the rib. Treatment of 29 patients with severe flail chest, classified into four groups is shown: group I was treated by IPPR, group II by IPPR plus surgical stabilization, group III by surgical stabilization only, and group IV by surgical stabilization after exploratory thoracotomy. The clinical results are discussed. We conclude that surgical stabilization of the paradoxial movement of the chest wall can avoid the use of the respirator or at least reduce the interval of IPPR to a short period during the initial recovery from trauma. Using type III struts, we have obtained stabilization of the flail chest in all cases even in patients with severe anterior paradoxical movement. The patients' tolerance of surgical stainless steel struts was good. Images PMID:1105874

    Historically, geothermal developments in Nevada are reported in text, map, and video format. Interactive computer graphics coupled with a three-dimensional map of Nevada are used here for the first time as both a teaching and promotional tool. This paper describes the design and construction of the first interactive map of Nevada`s Geothermal Developments. The purpose of the poster is to provide a {open_quotes}hands-on{close_quotes} learning environment for teachers and students in Nevada. Nevada presently generates approximately 210 megawatts (MWe) of electric power from twelve operating plants at ten sites, enough electricity for about 200,000 households. Nevada`s geothermal developments also include a variety of direct-use (non-electric) projects such as residential, commercial and industrial space heating. Together, these developments make Nevada number one, on a per capita basis, in the United States for geothermal energy utilization. To better understand where geothermal developments occur, and why they are important, a visual display of the major projects has been prepared by the Nevada Section of the Geothermal Resources Council. The poster will be augmented with a 35mm slide presentation that traces the origins of modern development from prehistoric applications by indigenous Native Americans to modern uses that began during the 1980`s. Features include Nevada`s first geothermal electric power plant at Wabuska, in Lyon County, and the 60 MWe Dixie Valley power plant, the largest in the State. The photo display includes direct use applications in the mining, aquaculture, and agriculture industries, as well as home heating examples. Engineering developments specific to Nevada include {open_quotes}air-cooled{close_quotes} binary geothermal power plants, which use no potable water. Economic and environmental issues associated with geothermal developments are also illustrated.

    In childhood, chest pain occurring at exercise is a common complaint. A cardiac etiology for it is exceptionally found, explaining that most children do not undergo systematic cardiological investigation. However, chest pain at exercise may manifest as the unique symptom of a viral myocarditis. Recognizing this form of myocardial injury, however, might help to avoid clinical deterioration by providing adequate care. In this paper, we report on two children presenting with the unique clinical symptom of chest pain related to physical activity and in whom laboratory and cardiac investigations suggested transient myocardial damage related to myocarditis.

    Rupture of the aorta is a relatively rare complication of blunt chest trauma, and traumatic rupture of the aortic valve is even rarer. Even though both result from blunt chest trauma, the causative mechanisms of aortic valve injury differ from those of descending aortic rupture. There are no previous reports in the literature of simultaneous injuries to both the descending aorta and the aortic valve. We report a case of a 70-year-old man who presented with traumatic aortic regurgitation combined with traumatic pseudoaneurysm of the aortic isthmus following blunt chest trauma, and its successful repair with a hybrid surgical strategy.

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

    2016-01-01

    Chest pain is a very common symptom and can be of cardiac or non-cardiac origin. It accounts for approximately 5.5 million annual emergency room visits in the United States, according to 2011 CDC data. Penetrating atherosclerotic aortic ulcer (PAU), an uncommon condition, is also a potential cause of chest pain. We here report the case of a 65-year-old woman who presented with atypical chest and back pain. The pain persisted for 4 weeks necessitating two emergency room visits. Initial tests were non-significant including cardiac troponins, an electrocardiogram (EKG), and a chest X-ray on her first visit. Upon her second visit, she underwent a computed tomography angiogram of chest with contrast which revealed a PAU with an intramural hematoma in descending aorta. The PAU was finally diagnosed with an exclusion of other chest pain causes. She was treated non-surgically with a blood pressure control strategy and pain management. After a 2-month period of smoking cessation and following the achievement of a controlled blood pressure, she felt well without chest pain. PMID:27406453

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

    A 67-year-old man presented with a crossbow injury sustained in a suicide attempt during which he fixed the crossbow to a table. Although he retired to bed without treatment on the day of the initial injury, his pain increased the following day, and he was admitted to our hospital. On arrival, his vital signs were stable and a 10-mm diameter crossbow arrow that had penetrated the right anterior chest remained in place. Chest computed tomography revealed suspected damage to the right middle lobe, diaphragm, and liver. A right anterior thoracotomy was performed with partial resection of the middle lobe, diaphragm repair, and arrest of hepatic bleeding. There were no complications, and his postoperative course was uneventful. On day 12 after surgery, he was transferred to the psychiatry department of another hospital for treatment of his depression.

    A 19-year-old man presented to the emergency department with a 3-week history of chest pain. Despite normal examination, bloods and observations of his chest X-ray revealed a large opacity in the middle and lower right zone. Further imaging revealed a multicystic mediastinal teratoma. He was admitted under the respiratory physicians who arranged further investigations and discussed his case with the lung and testicular multidisciplinary team. He was started on neoadjuvant chemotherapy with a plan for future definitive surgical resection. Four months later he suddenly deteriorated due to airway compression from the tumour. He underwent an emergency thoracotomy and tumour resection. He is currently doing well and is thought to have a good prognosis following complete resection of his tumour. This case report summarises this rare diagnosis and emphasises the need for careful evaluation of patients despite their initial well appearance, especially in patients who are reattending.

  5. A Review of Esophageal Chest Pain

    PubMed Central

    Coss-Adame, Enrique

    2015-01-01

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

    The appropriate management of atypical chest pain requires an integration of medical and behavioural treatments. Unnecessary medicalization can increase morbidity. A sensitivity to the behavioural factors contributing to symptoms and disability may reduce both. The purpose of this paper is to provide physicians with a cognitive-behavioural perspective of the nature of morbidity and disability associated with chronic chest discomfort; some strategies for detecting heretofore unsuspected disability associated with chronic chest pain and related discomfort in patients with organic findings (both cardiac and non-cardiac), as well those with no identifiable disease process or organic cause; and some simple behavioural and cognitive-behavioural therapeutic techniques for treating and preventing such problems.

    Frontal chest radiographs ("chest X-rays") are routinely used by medical personnel to assess patients for a wide range of suspected disorders. Often large numbers of images need to be analyzed. Furthermore, at times the images need to analyzed ("reported") when no radiological expert is available. A system which enhances the images in such a way that abnormalities are more obvious is likely to reduce the chance that an abnormality goes unnoticed. The authors previously reported the use of principal components analysis to derive a basis set of eigenimages from a training set made up of images from normal subjects. The work is here extended to investigate how best to emphasize the abnormalities in chest radiographs. Results are also reported for various forms of image normalizing transformations used in performing the eigenimage processing.

He had significant chest pain and chest X-ray was significant for revealed multiple rib fractures and negative. CT scan of the chest ruled out pulmonary embolism or aortic dissection. However, few hours later he developed hypotension requiring admission to medical intensive care unit and intravenous vasopressors. Further workup showed ST elevation myocardial infarction involving the anterior ECG leads. Emergent coronary angiography was performed with intervention to the mid-left anterior descending occlusion. Cardiogenic shock resolved and patient was discharged few days later. One-year follow-up with echocardiogram showed stable ischaemic cardiomyopathy with improved left ventricular ejection fraction to 50%. PMID:24769662

    The use of chest computed tomography (CT) as an imaging test for the evaluation of thoracic pathology has significantly increased during the last four decades. Although cardiopulmonary diseases often overlap in their clinical manifestation, radiologists tend to overlook the heart while interpreting routine chest CT. Recent advances in CT technology have led to significant reduction of heart motion artefacts and now allow for the identification of several cardiac findings on chest CT even without electrocardiogram (ECG) gating. These observations range from simple curiosity to both benign and malignant discoveries, to life-threatening discoveries. We here present a clinical and radiologic review of common and less common cardiac findings discovered on non-gated chest CT in order to draw the attention of radiologists and referring physicians to these possibilities.

    Coronary artery injury after blunt chest trauma is rare, but can be life-threatening, resulting in severe myocardial ischaemia and acute myocardial infarction. We report a case of a 56-year-old male who presented a few days after a blunt chest trauma with crescendo unstable angina. Coronary angiography demonstrated left main coronary artery dissection that was fixed with stent implantation. After a blunt chest trauma symptoms and electrocardiographic findings of a coronary dissection can be nonspecific and confounded by the chest tenderness. In such cases careful evaluation to rule out traumatic coronary injuries is warranted and early intervention should not be delayed in the presence of clear evidence of myocardial ischemia.

  12. The efficacy of bedside chest ultrasound: from accuracy to outcomes.

    PubMed

    2016-09-01

    For many respiratory physicians, point-of-care chest ultrasound is now an integral part of clinical practice. The diagnostic accuracy of ultrasound to detect abnormalities of the pleura, the lung parenchyma and the thoracic musculoskeletal system is well described. However, the efficacy of a test extends beyond just diagnostic accuracy. The true value of a test depends on the degree to which diagnostic accuracy efficacy influences decision-making efficacy, and the subsequent extent to which this impacts health outcome efficacy. We therefore reviewed the demonstrable levels of test efficacy for bedside ultrasound of the pleura, lung parenchyma and thoracic musculoskeletal system.For bedside ultrasound of the pleura, there is evidence supporting diagnostic accuracy efficacy, decision-making efficacy and health outcome efficacy, predominantly in guiding pleural interventions. For the lung parenchyma, chest ultrasound has an impact on diagnostic accuracy and decision-making for patients presenting with acute respiratory failure or breathlessness, but there are no data as yet on actual health outcomes. For ultrasound of the thoracic musculoskeletal system, there is robust evidence only for diagnostic accuracy efficacy.We therefore outline avenues to further validate bedside chest ultrasound beyond diagnostic accuracy, with an emphasis on confirming enhanced health outcomes.

    The image background resulting from imaged anatomy can be divided into those components that are meaningful to the observers, in the sense that they are recognised as separate structures, and those that are not. These latter components (reffered to as anatomical noise) can be removed using a method developed within the RADIUS group. The aim of the present study was to investigate whether the removal of the anatomical noise results in images where lung nodules with lower contrast can be detected. A receiver operating characteristic (ROC) study was therefore conducted using two types of images: clinical chest images and chest images in which the anatomical noise had been removed. Simulated designer nodules with a full-width-at-fifth-maximum of 10 mm but with varying contrast were added to the images. The contrast needed to obtain an area under the ROC curve of 0.80, C0.8, was used as a measure of detectability (a low value of C0.8 represents a high detectability). Five regions of the chest X ray were investigated and it was found that in all regions the removal of anatomical noise led to images with lower C0.8 than the original images. On average, C0.8 was 20% higher in the original images, ranging from 7% (the lateral pulmonary regions) to 41% (the upper mediastinal regions).

    Sixteen patients are presented who had sarcomas of the chest wall at a site where a prior malignancy had been irradiated. The first malignancies included breast cancer (ten cases), Hodgkin's disease (four cases), and others (two cases). Radiation doses varied from 4200 to 5500 R (mean, 4900 R). The latency period ranged from 5 to 28 years (mean, 13 years). The histologic types of the radiation-induced sarcomas were as follows: malignant fibrous histiocytoma, nine cases; osteosarcoma, six cases; and malignant mesenchymoma, one case. The only long-term survivor is alive and well 12 years after resection of a clavicular chondroblastic osteosarcoma. Three cases were recently diagnosed. Despite aggressive multimodality treatment, the remaining 13 patients have all died from their sarcomas (mean survival, 13.5 months). All patients have apparently been cured of their first malignancies. Chemotherapy was ineffective. No treatment, including forequarter amputation, appeared to palliate the patients with supraclavicular soft tissue sarcomas. Major chest wall resection offered good palliation for seven of eight patients with sarcomas arising in the sternum or lateral chest wall. Close follow-up is needed to detect signs of these sarcomas in the ever-increasing number of patients receiving therapeutic irradiation.

  15. Cardiac computed tomography in patients with acute chest pain.

    PubMed

    Nieman, Koen; Hoffmann, Udo

    2015-04-14

    The efficient and reliable evaluation of patients with acute chest pain is one of the most challenging tasks in the emergency department. Coronary computed tomography (CT) angiography may play a major role, since it permits ruling out coronary artery disease with high accuracy if performed with expertise in properly selected and prepared patients. Several randomized trials have established early cardiac CT as a viable safe and potentially more efficient alternative to functional testing in the evaluation of acute chest pain. Ongoing investigations explore whether advanced anatomic and functional assessments such as high-risk coronary plaque, resting myocardial perfusion, and left ventricular function, or the simulation of the fractional coronary flow reserve will add information to the anatomic assessment for stenosis, which would allow expanding the benefits of cardiac CT from triage to treatment decisions. Especially, the combination of high-sensitive troponins and coronary computed tomography angiography may play a valuable role in future strategies for the management of patients presenting with acute chest pain.

  16. Air pollution and ED visits for chest pain.

    2009-02-01

    This was a study of 157,028 emergency department (ED)-diagnosed visits for chest pain (International Classification of Diseases, Ninth Revision [ICD-9]: 786) in 6 cities in Canada. The generalized linear mixed methods technique was applied to analyze the relations between daily counts of ED visits for chest pain on the levels of ambient air pollutants after adjusting for meteorological variables. The daily counts of visits were analyzed separately for the whole period (January-December), warm (April-September), and cold (October-March). The results are presented in the form of the excess risks associated with an increase in the mean values of the pollutant concentrations. The highest increase was obtained for nitrogen dioxide (NO2) exposure in the warm period as follows: 5.9% (95% confidence interval, 3.3-5.8) for mean value equals to 20.1 ppb. The associations of ED visits for chest pain with air pollution are very similar to the associations of ED visits related to cardiac problems. PMID:19371523

  17. High-frequency chest compression: a summary of the literature.

    PubMed

    Dosman, Cara F; Jones, Richard L

    2005-01-01

    The purpose of the present literature summary is to describe high-frequency chest compression (HFCC), summarize its history and outline study results on its effect on mucolysis, mucus transport, pulmonary function and quality of life. HFCC is a mechanical method of self-administered chest physiotherapy, which induces rapid air movement in and out of the lungs. This mean oscillated volume is an effective method of mucolysis and mucus clearance. HFCC can increase independence. Some studies have shown that HFCC leads to more mucus clearance and better lung function compared with conventional chest physiotherapy. However, HFCC also decreases end-expiratory lung volume, which can lead to increased airway resistance and a decreased oscillated volume. Adding positive end-expiratory pressure to HFCC has been shown to prevent this decrease in end-expiratory lung volume and to increase the oscillated volume. It is possible that the HFCC-induced decrease in end-expiratory lung volume may result in more mucus clearance in airways that remain open by reducing airway size. Adjunctive methods, such as positive end-expiratory pressure, may not always be needed to make HFCC more effective.

  18. Musculoskeletal problems of the chest wall in athletes.

    PubMed

    Gregory, Peter L; Biswas, Anita C; Batt, Mark E

    2002-01-01

    Chest pain in the athlete has a wide differential diagnosis. Pain may originate from structures within the thorax, such as the heart, lungs or oesophagus. However, musculoskeletal causes of chest pain must be considered. The aim of this review is to help the clinician to diagnose chest wall pain in athletes by identifying the possible causes, as reported in the literature. Musculoskeletal problems of the chest wall can occur in the ribs, sternum, articulations or myofascial structures. The cause is usually evident in the case of direct trauma. Additionally, athletes' bodies may be subjected to sudden large indirect forces or overuse, and stress fractures of the ribs caused by sporting activity have been extensively reported. These have been associated with golf, rowing and baseball pitching in particular. Stress fractures of the sternum reported in wrestlers cause pain and tenderness of the sternum, as expected. Diagnosis is by bone scan and limitation of activity usually allows healing to occur. The slipping rib syndrome causes intermittent costal margin pain related to posture or movement, and may be diagnosed by the 'hooking manoeuvre', which reproduces pain and sometimes a click. If reassurance and postural advice fail, good results are possible with resection of the mobile rib. The painful xiphoid syndrome is a rare condition that causes pain and tenderness of the xiphoid and is self-limiting. Costochondritis is a self-limiting condition of unknown aetiology that typically presents with pain around the second to fifth costochondral joints. It can be differentiated from Tietze's syndrome in which there is swelling and pain of the articulation. Both conditions eventually settle spontaneously although a corticosteroid injection may be useful in particularly troublesome cases. The intercostal muscles may be injured causing tenderness between the ribs. Other conditions that should be considered include epidemic myalgia, precordial catch syndrome and referred pain

    Return of spontaneous circulation (ROSC) during chest compression is generally detected by arterial pulse palpation and end-tidal CO2 monitoring; however, it is necessary to stop chest compression during pulse palpation, and to perform endotracheal intubation for monitoring end-tidal CO2. In the present study, we evaluated whether near-infrared spectroscopy (NIRS) allows the detection of ROSC during chest compression without interruption. We monitored cerebral blood oxygenation in 19 patients with cardiac arrest using NIRS (NIRO-200NX, Hamamatsu Photonics, Japan). On arrival at the emergency room, the attending physicians immediately assessed whether a patient was eligible for this study after conventional advanced life support (ALS) and employed NIRS to measure cerebral blood oxygenation (CBO) in the bilateral frontal lobe in patients. We found cerebral blood flow waveforms in synchrony with chest compressions in all patients. In addition, we observed abrupt increases of oxy-hemoglobin concentration and tissue oxygen index (TOI), which were associated with ROSC detected by pulse palpation. The present findings indicate that NIRS can be used to assess the quality of chest compression in patients with cardiac arrest as demonstrated by the detection of synchronous waveforms during cardiopulmonary resuscitation (CPR). NIRS appears to be applicable for detection of ROSC without interruption of chest compression and without endotracheal intubation. PMID:26782207

    Portal hypertensive gastropathy (PHG) is a gastric mucosal lesion complicating portal hypertension, with higher prevalence in decompensated cirrhosis. PHG can sometimes complicate autosomal dominant polycystic kidney disease (ADPKD) due to the presence of multiple liver cysts. Besides, PHG is known to present as chest pain, with or without hematemesis. Other causes of chest pain in ADPKD include referred chest pain from progressively enlarging kidney cysts, and rare pericardial cysts. Chest pain, especially if pleuritic, in end-stage renal disease (ESRD) patients, is often ascribed to uremic pericarditis. We present recurrent pleuritic chest pain in a 24-year old ESRD patient with ADPKD that was initially misdiagnosed as uremic pericarditis. It was ultimately shown to represent symptomatic PHG with excellent therapeutic response to proton pump inhibitors. PMID:27069969

    Reconstruction of chest wall tumor is very important link of chest wall tumor resection. Many implants have been reported to be used to reconstruct the chest wall, such as steelwire, titanium mesh and polypropylene mesh. It is really hard for clinicians to decide which implant is the best one to replace the chest wall. We herein report a 68-year-old man who had underwent a chest wall reconstruction with a hernia repair piece and a Dacron hernia repair piece. The patient has maintained an excellent cosmetic and functional outcome since surgery, which proves that the hernia piece still has its place in reconstruction of chest wall. PMID:27293859

    Background Patients who visit online support groups benefit in various ways. Results of our earlier study indicated that participation in online support groups had a profound effect on the participants’ feelings of “being empowered.” However, most studies of online patient support groups have focused on the members of these groups who actively contribute by sending postings (posters). Thus far, little is known about the impact for “lurkers” (ie, those who do not actively participate by sending postings). Objective In the present study, we explored if lurkers in online patient support groups profit to the same extent as posters do. Methods We searched the Internet with the search engine Google to identify all Dutch online support groups for patients with breast cancer, fibromyalgia, and arthritis. Invitations to complete an online survey were sent out by the owners of 19 groups. In the online questionnaire, we asked questions about demographic and health characteristics, use of and satisfaction with the online support group, empowering processes, and empowering outcomes. The online questionnaire was completed by 528 individuals, of which 109 (21%) identified themselves as lurkers. Results Lurkers (mean age 47 years) were slightly older than active participants (mean age 43 years, P = .002), had a shorter disease history (time since diagnosis 3.7 years vs 5.4 years, P = .001), and reported lower mental well-being (SF 12 subscore 37.7 vs 40.5, P = .004). No significant differences were found in other demographic variables. Posters indicated visiting the online support groups significantly more often for social reasons, such as curiosity about how other members were doing, to enjoy themselves, as a part of their daily routine (all P < .001), and because other members expected them to be there (P = .003). Lurkers and posters did not differ in their information-related reasons for visiting the online support group. Lurkers were significantly less satisfied with

    To investigate the optimal beam quality for chest computed radiography (CR), we measured the radiographic contrast and evaluated the image quality of chest CR using various X-ray tube voltages. The contrast between lung and rib or heart increased on CR images obtained by lowering the tube voltage from 140 to 60 kV, but the degree of increase was less. Scattered radiation was reduced on CR images with a lower tube voltage. The Wiener spectrum of CR images with a low tube voltage showed a low value under identical conditions of amount of light stimulated emission. The quality of chest CR images obtained using a lower tube voltage (80 kV and 100 kV) was evaluated as being superior to those obtained with a higher tube voltage (120 kV and 140 kV). Considering the problem of tube loading and exposure in clinical applications, a tube voltage of 90 to 100 kV (0.1 mm copper filter backed by 0.5 mm aluminum) is recommended for chest CR.

  14. [Functional Outcome after Chest Wall Stabilisation].

    Kyriss, T; Lenz, U; Friedel, G

    2016-09-01

    This overview reviews the current literature to compare the functional results after surgical and conservative treatment of patients with flail chest and multiple rib fractures. Regarding functional aspects, patients in the early phase after a thoracic trauma are those that benefit most from the stabilisation of the chest wall by internal fixation of the ribs. Patients recover faster from restrictive respiratory disorders, have less pain and return to the workplace earlier after an operation compared with those that receive conservative treatment. In the medium term, however, patients that are treated conservatively also achieve normal pulmonary function values and become free of pain. The period of convalescence after blunt thoracic trauma is generally underestimated. Future studies of the functional outcome after severe chest injuries should take this into account and the development of functional parameters should be monitored for at least 24 months. A prospective data collection of early and long-term surgical results in registries would be suitable to evaluate benefits and indications of chest wall stabilisation. PMID:27607891

    Abstract Keloids are common in the Asian population. Multiple or huge keloids can appear on the chest wall because of its tendency to develop acne, sebaceous cyst, etc. It is difficult to find an ideal treatment for keloids in this area due to the limit of local soft tissues and higher recurrence rate. This study aims at establishing an individualized protocol that could be easily applied according to the size and number of chest wall keloids. A total of 445 patients received various methods (4 protocols) of treatment in our department from September 2006 to September 2012 according to the size and number of their chest wall keloids. All of the patients received adjuvant radiotherapy in our hospital. Patient and Observer Scar Assessment Scale (POSAS) was used to assess the treatment effect by both doctors and patients. With mean follow-up time of 13 months (range: 6–18 months), 362 patients participated in the assessment of POSAS with doctors. Both the doctors and the patients themselves used POSAS to evaluate the treatment effect. The recurrence rate was 0.83%. There was an obvious significant difference (P < 0.001) between the before-surgery score and the after-surgery score from both doctors and patients, indicating that both doctors and patients were satisfied with the treatment effect. Our preliminary clinical result indicates that good clinical results could be achieved by choosing the proper method in this algorithm for Chinese patients with chest wall keloids. This algorithm could play a guiding role for surgeons when dealing with chest wall keloid treatment. PMID:27583896

    Extensive chest wall resection carries the risk of difficult reconstruction and surgical complications. We report our experience on chest wall reconstruction using titanium plates for a wide thoracic defect after tumor resection. A 74-year-old man was diagnosed with chondrosarcoma of the 6th rib on the right. He needed extensive chest wall resection because of skip lesions on 4th rib noted on operative inspection, leaving a defect measuring 33 × 20 cm. Reconstruction using 5 transverse titanium plates sandwiched between an expanded polytetrafluoroethylene patch and a polypropylene mesh sheet stabilized the chest wall. This reconstruction allowed successful separation from ventilatory support after operation. The postoperative course was uneventful, and he was discharged on postoperative day 20. The advantages of this form of reconstruction over conventional prostheses are rigidity, and stability and usability. PMID:27365062

    There is a paucity of African-American Cancer researchers. To help address this, an educational collaboration was developed between a Comprehensive Cancer Center and a distant undergraduate biology department at a minority institution that sought to teach students introductory cancer biology while modeling research culture. A student-centered active learning curriculum was established that incorporated scientific poster presentations and simulated research exercises to foster learning of cancer biology. Students successfully mined primary literature for supportive data to test cancer-related hypotheses. Student feedback indicated that the poster project substantially enhanced depth of understanding of cancer biology and laid the groundwork for subsequent laboratory work. This inter-institutional collaboration modeled the research process while conveying facts and concepts about cancer.

    2013-03-01

    Background Chest physiotherapy and high-frequency chest wall oscillation (HFCWO) are routinely used after lung transplant to facilitate removal of secretions. To date, no studies have been done to investigate which therapy is more comfortable and preferred by lung transplant recipients. Patients who have less pain may mobilize secretions, heal, and recover faster. Objectives To compare effects of HFCWO versus chest physiotherapy on pain and preference in lung transplant recipients. Methods In a 2-group experimental, repeated-measures design, 45 lung transplant recipients (27 single lung, 18 bilateral) were randomized to chest physiotherapy (10 AM, 2 PM) followed by HFCWO (6 PM, 10 PM; group 1, n=22) or vice versa (group 2, n=23) on postoperative day 3. A verbal numeric rating scale was used to measure pain before and after treatment. At the end of the treatment sequence, a 4-item patient survey was administered to assess treatment preference, pain, and effectiveness. Data were analyzed with χ(2) and t tests and repeated-measures analysis of variance. Results A significant interaction was found between mean difference in pain scores from before to after treatment and treatment method; pain scores decreased more when HFCWO was done at 10 AM and 6 PM (P =.04). Bilateral transplant recipients showed a significant preference for HFCWO over chest physiotherapy (11 [85%] vs 2 [15%], P=.01). However, single lung recipients showed no significant difference in preference between the 2 treatments (11 [42%] vs 14 [54%]). Conclusions HFCWO seems to provide greater decreases in pain scores than does chest physiotherapy. Bilateral lung transplant recipients preferred HFCWO to chest physiotherapy. HFCWO may be an effective, feasible alternative to chest physiotherapy. (American Journal of Critical Care. 2013;22:115-125).

  1. Evaluation of chest pain in the emergency department.

    PubMed

    Jesse, R L; Kontos, M C

    1997-04-01

    The evaluation of chest pain in the emergency setting should be systematic, risk based, and goal driven. An effective program must be able to evaluate all patients with equal thoroughness under the assumption that any patient with chest pain could potentially be having an MI. The initial evaluation is based on the history, a focused physical examination, and the ECG. This information is sufficient to categorize patients into groups at high, moderate, and low risk. Table 14 is a template for a comprehensive chest-pain evaluation program. Patients at high risk need rapid initiation of appropriate therapy: thrombolytics or primary angioplasty for the patients with MIs or aspirin/heparin for the patients with unstable angina. Patients at moderate risk need to have an acute coronary syndrome ruled in or out expediently and additional comorbidities addressed before discharge. Patients at low risk also need to be evaluated, and once the likelihood of an unstable acute coronary syndrome is eliminated, they can be discharged with further evaluation performed as outpatients. Subsequent evaluation should attempt to assign a definitive diagnosis while also addressing issues specific to risk reduction, such as cholesterol lowering and smoking cessation. It is well documented that 4% to 5% of patients with MIs are inadvertently missed during the initial evaluation. This number is surprisingly consistent among many studies using various protocols and suggests that an initial evaluation limited to the history, physical examination, and ECG will fail to identify the small number of these patients who otherwise appear at low risk. The solution is to improve the sensitivity of the evaluation process to identify these patients. It appears that more than simple observation is required, and at the present time, no simple laboratory test can meet this need. However, success has been reported with a number of strategies including emergency imaging with either radionuclides such as

    Background 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. Methods and Findings 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.

    1988-08-01

    A ten year review of 31 patients with chest wall complications associated with radiation therapy is presented. Carcinoma of the breast accounted for 23 instances, postradiation sarcomas for five and other complications for three. Twenty patients had radionecrotic ulcerations, nine of which were found to contain recurrent malignant disease. This finding significantly and unfavorably influenced survival in comparison with those whose ulcer was free of tumor (p less than or equal to 0.0001). Of 27 surgically treated patients, the regimen which correlated with the fewest complications included extensive removal of all poor quality tissue, avoidance of prosthetic materials and bone grafts and immediate reconstruction with well vascularized muscle or omental flaps.

    Melioidosis caused by Burkholderia pseudomallei, an important human pathogen in the tropical regions causes protean and multisystem clinical manifestations. A 50-year-old man on treatment for pulmonary tuberculosis developed a chest wall abscess. With a suspicion of tuberculous cold abscess, pus culture was done and it revealed Burkholderia pseudomallei. He was treated with 10 days of ceftazidime and incision and drainage was done. Wound healed well and he has now completed three months of oral cotrimoxazole eradication therapy and is on follow-up without recurrence. We report this case for the unusual presentation of melioidosis and the diagnostic challenge posed due to clinical similarity with tuberculosis. PMID:23741590

    This poster describes the NREL/Alstom Wind testing and model verification of the Alstom 3-MW wind turbine located at NREL's National Wind Technology Center. NREL,in collaboration with ALSTOM Wind, is studying a 3-MW wind turbine installed at the National Wind Technology Center(NWTC). The project analyzes the turbine design using a state-of-the-art simulation code validated with detailed test data. This poster describes the testing and the model validation effort, and provides conclusions about the performance of the unique drive train configuration used in this wind turbine. The 3-MW machine has been operating at the NWTC since March 2011, and drive train measurements will be collected through the spring of 2012. The NWTC testing site has particularly turbulent wind patterns that allow for the measurement of large transient loads and the resulting turbine response. This poster describes the 3-MW turbine test project, the instrumentation installed, and the load cases captured. The design of a reliable wind turbine drive train increasingly relies on the use of advanced simulation to predict structural responses in a varying wind field. This poster presents a fully coupled, aero-elastic and dynamic model of the wind turbine. It also shows the methodology used to validate the model, including the use of measured tower modes, model-to-model comparisons of the power curve, and mainshaft bending predictions for various load cases. The drivetrain is designed to only transmit torque to the gearbox, eliminating non-torque moments that are known to cause gear misalignment. Preliminary results show that the drivetrain is able to divert bending loads in extreme loading cases, and that a significantly smaller bending moment is induced on the mainshaft compared to a three-point mounting design.

  19. Clinical decision aids for chest pain in the emergency department: identifying low-risk patients

    2015-01-01

    Chest pain is one of the most common presenting complaints in the emergency department, though only a small minority of patients are subsequently diagnosed with acute coronary syndrome (ACS). However, missing the diagnosis has potential for significant morbidity and mortality. ACS presentations can be atypical, and their workups are often prolonged and costly. In order to risk-stratify patients and better direct the workup and care given, many decision aids have been developed. While each may have merit in certain clinical settings, the most useful aid in the emergency department is one that finds all cases of ACS while also identifying a substantial subset of patients at low risk who can be discharged without stress testing or coronary angiography. This review describes several of the chest pain decision aids developed and studied through the recent past, starting with the thrombolysis in myocardial infarction (TIMI) risk score and Global Registry of Acute Coronary Events (GRACE) scores, which were developed as prognostic aids for patients already diagnosed with ACS, then subsequently validated in the undifferentiated chest pain population. Asia-Pacific Evaluation of Chest Pain Trial (ASPECT); Accelerated Diagnostic Protocol to Assess Patients With Chest Pain Symptoms Using Contemporary Troponins (ADAPT); North American Chest Pain Rule (NACPR); and History, Electrocardiogram, Age, Risk factors, Troponin (HEART) score have been developed exclusively for use in the undifferentiated chest pain population as well, with improved performance compared to their predecessors. This review describes the relative merits and limitations of these decision aids so that providers can determine which tool fits the needs of their clinical practice setting. PMID:27147894

  20. Traumatic chest injury in children: A single thoracic surgeon's experience in two Nigerian tertiary hospitals

    Okonta, Kelechi Emmanuel

    2015-01-01

    Background: This study was to determine the extent and outcome of childhood chest injury in Nigeria, and to compare results with that of other literatures. Patients and Methods: A Prospective study of all children under 18 years of age with chest trauma in two tertiary hospitals in Southern Nigeria from January 2012 to December 2014 was reviewed. The aetiology, type, associated injury, mechanism, treatment and outcome were evaluated. The patients were followed up in the clinic. The data were analysed using SPSS version 20.0 with a significant P < 0.05. Results: Thirty-one patients (12.1%) under 18 years of age of 256 chest trauma patients were managed in the thoracic units. The mean age was 9.78 ± 6.77 years and 27 (87.1%) were male. The aetiology in 13 was from falls, 10 from automobile crashes, 3 from gunshots, 4 from stabbing and 1 from abuse. The highest peak of chest injury was on Saturday of the week and April of the year. The pleural collections are as follows: 15 (71.4%) was haemothorax, 4 (19.1%) pneumothorax, 2 (9.5%) haemopneumothorax and 18 patients had lung contusion in combination or alone with the pleural collections. Seven patients who presented >12-h versus 2 who presented <12-h and 6 of children between 0 and 9 years versus 3 at 10-18 years of age had empyema thoracis (P value not significant). One death was recorded. Conclusion: Chest trauma in children is still not common, and blunt chest injury from falls and automobile accidents are more common than penetrating chest injury. Treatment with tube thoracostomy is the major management modality with empyema thoracis as the most common complication. PMID:26612123

  1. Spontaneous Pneumomediastinum: A Rare Disease Associated with Chest Pain in Adolescents

    PubMed Central

    2015-01-01

    Purpose Spontaneous pneumomediastinum (SPM) is a rare entity, with only a few cases reported, especially in adolescents. We aimed to analyze the clinical characteristics of SPM in adolescents and the diagnostic implications of computed tomography (CT) and esophagography therein. Materials and Methods This retrospective descriptive study was conducted as a review of medical records of 416 adolescents (10-18 years of age) with chest pain from March 2005 to June 2013. Information on clinical presentation, methods of diagnosis, hospital stay, and outcomes were collected and analyzed. Results Among adolescents complaining of chest pain, 11 patients had SPM (11/416, 2.64%). All patients presented with pleuritic chest pain, and 54.5% reported neck pain as the most common associated complaint. Clinical findings were nonspecific, and initial chest X-ray assessment was diagnostic only in three of 11 patients. However, reassessment of chest X-ray revealed diagnostic findings of SPM in five of the remaining eight patients. CT was diagnostic in all patients, while esophagography and echocardiogram were uninformative. Symptomatic improvement was noted within 2.45±1.2 hours (range, 0.5 to 4) after supportive care; mean hospital stay was 4.54±0.99 days (range, 2 to 6). No recurrence was observed. Conclusion SPM is a rare disease that should be considered in adolescent patients with pleuritic chest pain. Careful reading of initial chest X-rays is important to avoiding further unnecessary investigations. SPM is self-limited and treatment is supportive; nevertheless, if there are no indications of esophageal rupture, urgent esophagography is not recommended. PMID:26256992

    Currently available diagnostic techniques for myocardial contusion following blunt chest trauma were evaluated. We investigated 30 patients prospectively over a period of 1 year for the presence of myocardial contusion. Among the 30 patients, eight were found to have myocardial contusion on the basis of abnormal electrocardiograms, elevated creatine phosphokinase MB fraction (CPK-MB), and positive myocardial scan. Myocardial scan was positive in seven of eight patients (87.5%). CPK-MB fraction was elevated in four of eight patients (50%). Definitive electrocardiographic changes were seen in only two of eight patients (25%). It appears that myocardial scan using technetium pyrophosphate and CPK-MB fraction determinations are the most reliable aids in diagnosis of myocardial contusion following blunt chest trauma.

  3. Penetrating chest wounds: a 10-year review.

    PubMed

    Sett, S S; Busse, E; Boyd, T; Burgess, J

    1987-09-01

    From January 1975 to December 1984, 93 patients with penetrating chest wounds were admitted to three hospitals in Regina. Sixty-three percent of the wounds were caused by knives and 34% by firearms. Sixty-three patients were treated conservatively, 18 patients had thoracotomy and 12 others underwent laparotomy. Of the 18 patients, 16 had wounds between the nipples; 8 of the 16 had injuries to the heart or great vessels. Whereas the majority of penetrating wounds to the chest may be treated by observation or thoracostomy alone, a surgical approach is recommended when penetrating injuries are thought to have traversed the mediastinum, because of the high incidence of associated cardiac injuries. In doubtful cases the decision should favour early thoracotomy.

    Over the last 5 years, 14 patients were treated by wide en bloc resection of chest wall tumors with primary reconstruction. There were nine females and five male patients with an age range of 31-77 years. All patients had a skeletal resection of the chest wall. An average of 3.9 ribs were resected in the patients treated. In three patients a partial sternectomy was carried out in conjunction with the rib resections. Chest wall skeletal defects were reconstructed with Prolene mesh, which was placed under tension. Soft tissue reconstruction utilized selected portions of the latissimus dorsi musculocutaneous territory with fasciocutaneous extensions beyond the muscle itself. Primary healing was obtained in all patients and secondary procedures were not required. The average hospitalization was 23 days. All patients survived the resection and reconstruction and were alive 30 days after operation. In selected patients the preservation of a portion of the innervated muscle in situ or the transfer of the muscle with the preservation of its resting length has maintained the majority of the muscle function.

  8. Surface Chest Motion Decomposition for Cardiovascular Monitoring

    NASA Astrophysics Data System (ADS)

    Shafiq, Ghufran; Veluvolu, Kalyana C.

    2014-05-01

    Surface chest motion can be easily monitored with a wide variety of sensors such as pressure belts, fiber Bragg gratings and inertial sensors, etc. The current applications of these sensors are mainly restricted to respiratory motion monitoring/analysis due to the technical challenges involved in separation of the cardiac motion from the dominant respiratory motion. The contribution of heart to the surface chest motion is relatively very small as compared to the respiratory motion. Further, the heart motion spectrally overlaps with the respiratory harmonics and their separation becomes even more challenging. In this paper, we approach this source separation problem with independent component analysis (ICA) framework. ICA with reference (ICA-R) yields only desired component with improved separation, but the method is highly sensitive to the reference generation. Several reference generation approaches are developed to solve the problem. Experimental validation of these proposed approaches is performed with chest displacement data and ECG obtained from healthy subjects under normal breathing and post-exercise conditions. The extracted component morphologically matches well with the collected ECG. Results show that the proposed methods perform better than conventional band pass filtering.

    Cardiac CT has developed into a robust clinical tool during the past 15 years. Of the fields in which the potential of cardiac CT has raised more interest is chest pain in acute settings. In fact, the possibility to exclude with high reliability obstructive coronary artery disease (CAD) in patients at low-to-intermediate risk is of great interest both from the clinical standpoint and from the management standpoint. Several other modalities, with or without imaging, have been used during the past decades in the settings of new onset chest pain or in acute chest pain for both diagnostic and prognostic assessment of CAD. Each one has advantages and disadvantages. Most imaging modalities also focus on inducible ischaemia to guide referral to invasive coronary angiography. The advent of cardiac CT has introduced a new practice diagnostic paradigm, being the most accurate non-invasive method for identification and exclusion of CAD. Furthermore, the detection of subclinical CAD and plaque imaging offer the opportunity to improve risk stratification. Moreover, recent advances of the latest generation CT scanners allow combining both anatomical and functional imaging by stress myocardial perfusion. The role of cardiac CT in acute settings is already important and will become progressively more important in the coming years. PMID:26866681

  10. Surface Chest Motion Decomposition for Cardiovascular Monitoring

    Surface chest motion can be easily monitored with a wide variety of sensors such as pressure belts, fiber Bragg gratings and inertial sensors, etc. The current applications of these sensors are mainly restricted to respiratory motion monitoring/analysis due to the technical challenges involved in separation of the cardiac motion from the dominant respiratory motion. The contribution of heart to the surface chest motion is relatively very small as compared to the respiratory motion. Further, the heart motion spectrally overlaps with the respiratory harmonics and their separation becomes even more challenging. In this paper, we approach this source separation problem with independent component analysis (ICA) framework. ICA with reference (ICA-R) yields only desired component with improved separation, but the method is highly sensitive to the reference generation. Several reference generation approaches are developed to solve the problem. Experimental validation of these proposed approaches is performed with chest displacement data and ECG obtained from healthy subjects under normal breathing and post-exercise conditions. The extracted component morphologically matches well with the collected ECG. Results show that the proposed methods perform better than conventional band pass filtering. PMID:24865183

  11. Penetrating chest wound: a case report.

    An unusual penetrating chest injury was caused by a ball-point pen. Because of apparent penetration of the heart, preparations were made for an emergency open-heart procedure before emergency thoracotomy was undertaken, with the pen still in situ. The pen had bruised the epicardium but had not penetrated the pericardial sac. After removal of the pen, the wound was closed and a chest tube left in place. Recovery, apart from minor degrees of basal atelectasis, pleural effusion and wound infection, was uneventful. The outcome was consistent with that associated with current aggressive management of penetrating chest injuries. Management is based on three approaches. The primary one is intercostal thoracostomy tube drainage and fluid and blood replacement. In cases of massive hemorrhage or air leak, thoracotomy is necessary. The third approach is to prevent post-traumatic pulmonary insufficiency by using fine, high-efficiency filters during blood transfusion, avoiding excessive administration of intravenous fluids, performing tracheostomy after prolonged endotracheal intubation, and using a volume respirator with positive end-expiratory pressure. The average mortality for penetrating wounds of the heart is 25%.

    In connection with the problems of the ingestion of hot exhaust gases in engines of V/STOL and STOVL aircraft in ground effect, a series of studies have been undertaken. Ground impinging, two- and three-poster jets operating in the presence of cross flow were studied. The current paper is divided into two parts. The first part is a comparison of the low speed, two-, three-, and four-poster jet cases, with respect to the flowfield in the region of interaction between the forward and the jet flows. These include cases with mass balanced inlet suction. An analysis of the inlet entry plane of the low speed two- and three-poster jet cases is also given. In the second part, high speed results for a two jet configuration without inlet suction are given. The results are based on quantitative, marker concentration distributions obtained by digitizing video images.

    The widespread adoption of chest CT for lung cancer screening will greatly increase the workload of chest radiologists. Contributing to this effort is the need for radiologists to differentiate between localized nodules and slices through linear structures such as blood vessels, in each of a large number of slices acquired for each subject. To increase efficiency and accuracy, thin slices can be combined to provide thicker slabs for presentation, but the resulting superposition of tissues can make it more difficult to detect and characterize smaller nodules. The stereo display of a stack of thin CT slices may be able to clarify three-dimensional structures, while avoiding the loss of resolution and ambiguities due to tissue superposition. The current work focuses on the development and evaluation of stereo projection models that are appropriate for chest CT. As slices are combined into a three dimensional structure, maximum image intensity, which is limited by the display, must be preserved. But, compositing methods that effectively average slices together typically reduce contrast of subtle nodules. For monoscopic viewing, orthographic maximum-intensity projection (MIP), of thick slabs, has been employed to overcome this effect, but this method provides no information of depth or of the geometrical relationships between structures. Our comparison of various rendering options indicates that a stereographic perspective transformation, used in conjunction with a compositing model that combines maximum-intensity projection with an appropriate brightness weighting function, shows promise for this application. The main drawback uncovered was that, for the images used in this study, the lung volume was undersampled in the z-direction, resulting in certain unavoidable image artifacts.

  14. Primary malignant chest wall tumors: analysis of 40 patients

    2014-01-01

    Background Primary chest wall tumors originate from different constructions of thoracic wall. We report our multidisciplinary experience on primary thoracic tumor resection and thoracic reconstruction, the need to additional therapy and evaluating prognostic factors affecting survival. Methods We performed a retrospective review of our prospectively maintained database of 40 patients treated for malignant primary chest wall tumor from 1989 to 2009. Patients were evaluated in terms of age, sex, clinical presentation, type of imaging, tissue diagnosis methods, pathology, surgical technique, early complications, hospital mortality, prevalence of recurrence and distant metastases, additional treatment, 3 years survival and factors affecting survival. Results Male/Female (F/M) = 1, with median age of 43.72 years. Mass was the most common symptoms and the soft tissue sarcoma was the most common pathology. Resection without reconstruction was performed in 5 patients and Thirty-five patients (87.5%) had extensive resection and reconstruction with rotatory muscular flap, prosthetic mesh and/or cement. Overall, 12.5% (5/40) of patients received neoadjuvant therapy and 75% (30/40) of patients were treated with adjuvant therapy. The 3-year survival rate was 65%. Recurrences occurred in 24 patients (60%), 14 developed local recurrences, and 10 developed distant metastases. The primary treatment modality for both local and distant recurrences was surgical resection; among them, 10 underwent repeated resection, 9 adjuvant therapy and 5 were treated with lung metastasectomy. The most common site of distant metastasis was lung (n = 7). Factors that affected survival were type of pathology and evidence of distant metastasis. Conclusion Surgery with wide margin is the safe and good technique for treatment of primary chest wall tumors with acceptable morbidity and mortality. PMID:24947314

    Diaphragmatic injury is an uncommon traumatic injury (<1%). Although most diaphragmatic injuries can be obvious (eg, herniation of abdominal contents on chest radiograph), some injuries may be subtle and imaging studies can be nondiagnostic in many situations. Patients with diaphragmatic hernia either traumatic or nontraumatic may initially have no symptoms or signs to suggest an injury to the diaphragm.Here, we report a case of a 75-year-old woman diagnosed with irritable bowel syndrome -associated dominant constipation, presented with shortness of breath, cough, expectoration, tachycardia, and chest pain. Dextrocardia was an incidental finding, diagnosed by electrocardiography, chest radiograph, and CT chest. Parts of the colon, small intestine, and stomach were within the thorax in the left side due to left diaphragmatic hernia of a nontraumatic cause. Acquired incidental dextrocardia was the main problem due to displacement of the heart to contralateral side by the GI (gastrointestinal) viscera (left diaphragmatic hernia).The patient was prepared for the laparoscopic surgical repair, using a polyethylene mesh 20 cm to close the defect, and the patient recovered with accepted general condition. However, 5 days postoperative, the patient passed away suddenly due to unexplained cardiac arrest.Intrathoracic herniation of abdominal viscera should be considered in patients presented with sudden chest pain concomitant with a history of increased intra-abdominal pressure.

    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. PMID:27004154

    2001-06-01

    OBJECTIVE: To present a practical overview of the methods and techniques of auscultation of the chest and abdomen for use during the physical examination of athletes. Our intent is to provide information on this clinical technique to assist athletic trainers in recognizing and referring athletes presenting with potentially serious internal organ conditions. BACKGROUND: Use of the stethoscope is a clinical skill increasingly necessary for athletic trainers. Given the expanding breadth of both the assessment techniques used by athletic trainers and the populations they care for and the fact that clinical instruction guidelines have changed in the newly adopted National Athletic Trainers' Association Educational Competencies, our goal is to provide a framework upon which future instruction can be based. DESCRIPTION: This review covers the use of a stethoscope for auscultation of the chest and abdomen. Auscultation of the heart is covered first, followed by techniques for auscultating the breath sounds. Lastly, auscultation of the abdomen describes techniques for listening for bowel sounds and arterial bruits. CLINICAL ADVANTAGES: During the assessment of injuries to and illnesses of athletes, knowledge of auscultatory techniques is valuable and of increasing importance to athletic trainers. Athletic trainers who do not know how to perform auscultation may fail to recognize, and therefore fail to refer for further evaluation, athletes with potentially serious pathologic conditions.

    Aims Illicit cocaine consumption in Spain is one of the highest in Europe. Our objective was to study the incidence of undisclosed cocaine consumption in patients attending in two Spanish Emergency Departments for chest pain. Methods We analysed urine samples from consenting consecutive patients attending ED for chest pain to determine the presence of cocaine, and other drugs, by semiquantative tests with fluorescence polarization immunoassay (FPIA). Results Of 140 cases, 15.7 presented positive test for drugs, and cocaine was present in 6.4%. All cocaine-positive patients were younger (p < 0.001); none was admitted to Hospital (p = 0.08). No significant differences in ED stay or need for hospitalization were found between cocaine-positive and negative patients. Conclusion This finding in chest pain patients who consented to urine analysis suggests that the true incidence of cocaine use leading to such ED visits may be higher. PMID:19254377

    Ultra-low dose chest CT (ULD-CT) is acquired at a radiation dose lowered to that of a PA and lateral chest X-ray. Its image quality is degraded, yet remains diagnostic in many clinical indications. Technological improvements, with iterative reconstruction at the foreground, allowed a strong increase in the image quality obtained with this examination, which is achievable on most recent (<5 years) scanner. Established clinical indications of ULD-CT are increasing, and its non-inferiority compared to the reference "full dose" chest CT are currently demonstrated for the detection of solid nodules, for asbestos-related pleural diseases screening and for the monitoring of infectious pneumonia. Its current limitations are the obese patients (BMI>35) and the interstitial pneumonia, situations in which their performances are insufficient. PMID:26830922

    Typical human paragonimiasis demonstrates an elevated eosinophil count, positive immunoblot, nodular shadows of the lung and pleural thickening with pleural effusion, and these symptoms may be confused with chest cancer. In the present case, a rare case of human paragonimiasis mimicking chest cancer and abdominal wall metastasis is described, the 39-year-old male patient was admitted in our hospital for cough, weight loss 5 kg and a firm mass in right upper abdominal wall. The laboratory test showed unremarkable hematology and biochemistry results. Chest X-ray, Plain computed tomography of the chest and abdomen showed right pleural effusion, several nodules in right lower lung and a mass in the right upper abdominal wall. The initial diagnosis was lung or chest cancer with abdominal wall metastasis, and the abdominal wall mass was resected for the final diagnosis. The biopsy revealed eosinophilic granuloma with Charcot-Leyden crystal formation infiltrated in the muscular fibers. Subsequent to assessment of the antibodies against parasites, the final diagnosis of paragonimiasis was made. PMID:27313691

    The two main goals of chest pain units are the early, accurate diagnosis of acute coronary syndromes and the rapid, efficient recognition of low-risk patients who do not need hospital admission. Many clinical, practical, and economic reasons support the establishment of such units. Patients with chest pain account for a substantial proportion of emergency room turnover and their care is still far from optimal: 8% of patients sent home are later diagnosed of acute coronary syndrome and 60% of admissions for chest pain eventually prove to have been unnecessary.We present a systematic approach to create and manage a chest pain unit employing specialists headed by a cardiologist. The unit may be functional or located in a separate area of the emergency room. Initial triage is based on the clinical characteristics, the ECG and biomarkers of myocardial infarct. Risk stratification in the second phase selects patients to be admitted to the chest pain unit for 6-12 h. Finally, we propose treadmill testing before discharge to rule out the presence of acute myocardial ischemia or damage in patients with negative biomarkers and non-diagnostic serial ECGs.

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

    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.

    Objective Baseline results of the Studio OSservazionale (SOS), observational study, a single-arm observational study of digital chest tomosynthesis for lung cancer detection in an at-risk population demonstrated a detection rate of lung cancer comparable to that of studies that used low dose CT scan (LDCT). We present the results of the first round. Methods Totally 1,703 out of 1,843 (92%) subjects who had a baseline digital chest tomosynthesis underwent a first round reevaluation after 1 year. Results At first round chest digital tomosynthesis, 13 (0.7%) subjects had an indeterminate nodule larger than 5 mm and underwent low-dose CT scan for nodule confirmation. PET/CT study was obtained in 10 (0.5%) subjects and 2 subjects had a low-dose CT follow up. Surgery, either video-assisted thoracoscopic or open surgery for indeterminate pulmonary nodules was performed in 10 (0.2%) subjects. A lung cancer was diagnosed and resected in five patients. The lung cancer detection rate at first round was 0.3% (5/1,703). Conclusions The detection rate of lung cancer at first round for tomosynthesis is comparable to rates reported for CT. In addition, results of first round digital chest tomosynthesis confirm chest tomosynthesis as a possible first-line lung cancer-screening tool. PMID:25992366

    Ribs and clavicles in posterior-anterior (PA) digital chest radiographs often overlap with lung abnormalities such as nodules, and cause missing of these abnormalities, it is therefore necessary to remove or reduce the ribs in chest radiographs. The purpose of this study was to develop a fully automated algorithm to segment ribs within lung area in digital radiography (DR) for removal of the ribs. The rib segmentation algorithm consists of three steps. Firstly, a radiograph was pre-processed for contrast adjustment and noise removal; second, generalized Hough transform was employed to localize the lower boundary of the ribs. In the third step, a novel bilateral dynamic programming algorithm was used to accurately segment the upper and lower boundaries of ribs simultaneously. The width of the ribs and the smoothness of the rib boundaries were incorporated in the cost function of the bilateral dynamic programming for obtaining consistent results for the upper and lower boundaries. Our database consisted of 93 DR images, including, respectively, 23 and 70 images acquired with a DR system from Shanghai United-Imaging Healthcare Co. and from GE Healthcare Co. The rib localization algorithm achieved a sensitivity of 98.2% with 0.1 false positives per image. The accuracy of the detected ribs was further evaluated subjectively in 3 levels: "1", good; "2", acceptable; "3", poor. The percentages of good, acceptable, and poor segmentation results were 91.1%, 7.2%, and 1.7%, respectively. Our algorithm can obtain good segmentation results for ribs in chest radiography and would be useful for rib reduction in our future study.

    A posterior upper arm flap based on the profunda brachii vessels has been described to cover soft-tissue defects in the upper anterolateral chest. In our series, the posterior upper arm skin is elevated with the long head of the triceps muscle to cover seven chest-wall defects resulting from indolent postradiation open wounds following partial TRAM flap failure (n = 2), soft-tissue deficiencies following partial TRAM flap loss (n = 3), and primarily as an ancillary flap in TRAM flap breast reconstruction (n = 2). This flap also may be used to supply well-vascularized tissue in the regions of the shoulder, axilla, and posterolateral back. A prerequisite for this operation is redundant tissue of the upper arm often present in middle-aged women and in patients with lymphedema following mastectomy. In our series of seven patients, all donor sites were closed primarily, and there was no subjective functional deficit following transfer of the long head of the triceps muscle.

    Chest wall reconstruction represents one of the most challenging tasks in plastic surgery. Over the past several decades, a more profound understanding of surgical anatomy and physiology along with tremendous advances in surgical technique have resulted in substantial improvements in postoperative outcomes. Conceptually, the reconstructive goals include dead space obliteration, restoration of skeletal stability with protection of intrathoracic structures, and stable soft tissue coverage. Ideally, these goals are achieved with minimal aesthetic deformity. J. Surg. Oncol. 2016;113:913-922. © 2016 Wiley Periodicals, Inc. PMID:26969557

    In elderly patients, a blunt trauma of the chest is associated with a significant risk of complications and mortality. The number of ribs fractures (≥ 4), the presence of bilateral rib fractures, of a pulmonary contusion, of existent comorbidities or acute extra-thoracic traumatic lesions, and lastly the severity of thoracic pain, are indeed important risk factors of complications and mortality. Their presence may require hospitalization of the patient. When complications do occur, they are represented by alveolar hypoventilation, pulmonary atelectasia and broncho-pulmonary infections. When hospitalization is required, it may allow for the specific treatment of thoracic pain, including locoregional anesthesia techniques. PMID:26449103

    Most pitfalls in the interpretation of pediatric chest imaging are closely related with the technique used and the characteristics of pediatric patients. To obtain a quality image that will enable the correct diagnosis, it is very important to use an appropriate technique. It is important to know how technical factors influence the image and to be aware of the possible artifacts that can result from poor patient cooperation. Moreover, radiologists need to be familiar with the normal anatomy in children, with the classic radiologic findings, and with the anatomic and developmental variants to avoid misinterpreting normal findings as pathological.

    We present the case of a 13.5-year-old girl who was admitted to the Pediatric Surgery Department from the Pediatric Department of a district hospital, where she stayed because of stomachache and vomiting. Interview revealed blunt injury of the epigastrium a week ago. Chest X-ray revealed a loss of the right diaphragmatic outline, irregular radiolucency on the right side of the chest, collapsed right lung and mediastinal displacement to the left. The patient was operated on, and the surgery revealed herniation of the intestines and half of the stomach into the defect of the right dome of the diaphragm. The patient made an uneventful postoperative recovery. A small innate defect of the diaphragm can remain asymptomatic and undiagnosed as long as there is no herniation of the abdominal organs into the chest. PMID:27516794

    Without proper treatment, the mortality of pulmonary mucormycosis is nearly 100%. Although the diagnosis is often made histologically, it can be suspected when patients have a reverse halo sign on computed tomography (CT) of the chest, along with the right clinical findings. We describe the case of a woman 7 months post renal transplant who presented with fevers, malaise, and chest pain. Her chest CT revealed a round, focal area of ground-glass attenuation surrounded by a complete rim of consolidation in the left upper lobe, consistent with the reverse halo sign. Pulmonary mucormycosis was diagnosed by transbronchial lung biopsy. She was successfully treated with combined medical and surgical therapies. In the context of this case, we provide a brief review of the diagnosis of pulmonary mucormycosis, with a focus on radiographic and pathologic findings. PMID:24289813

    Fibrous tumour of the pleural is rare and controversial tumor. Most of the reported cases is adults and the elderly. This case presentation is a solitary fibrous tumour in a fifteen year old girl, which to the best of our knowledge is the youngest report, who was sent for a psychiatric evaluation due to persistent complaint of "movement" in her chest, later referred to a tuberculosis clinic because of a chest radiograph report of loculated pleural effusion likely secondary to tuberculosis. She eventually had a chest computerized tomography and subsequent resection of the lesion. Histology confirmed the computerized tomography diagnosis of solitary fibrous tumour and there was no recurrence five years after excision. This report highlights the difficulty often encountered in developing countries where clinicians solely rely on clinical acumen for diagnosis and treatment due to poor patients' financial status and scarcely available diagnostic resources.

    The objective of the present study was to develop the method for the determination of the position of the upper extremities at the moment of formation of the punctured-incised wounds in the chest canals taking into consideration peculiarities of their structure. A few series of experiments carried out for this purpose involving different positions of the upper extremities made it possible to evaluate the degree of displacement of the tissues in different chest regions and characterize disjunctive (disruptive) dislocation of the wound canals. The reconstruction of rectilinearity of the chest channel made it possible to demonstrate the possibility of establishing the initial position of the upper extremity at the moment of infliction of injury. The validity of the results of the study is illustrated by the example of practical forensic medical expertise. PMID:25764857

    Introduction High-frequency chest wall oscillation (HFCWO) has been traditionally implemented for airway secretion clearance in conditions such as cystic fibrosis (CF) and bronchiectasis. There have been few reports of its use in refractory asthma. Case report A 36-year-old, non-smoker male presented with a lifelong history of poorly controlled asthma. Despite multiple controller medications, he reported daily chest congestion, copious phlegm, and frequent exacerbations. Imaging, blood work, and bronchoscopy ruled out atypical infections, immunodeficiency, CF, and other chronic conditions. Pulmonary function tests supported a diagnosis of asthma. Results We initiated HFCWO therapy twice daily in addition to standard inhaled pharmacological therapy. After 2 months, the patient noted resolution of respiratory symptoms as well as improvement in lung function. He remained symptom-free at his 2-year follow-up. Conclusion High-frequency chest oscillation may be useful in phenotypes of asthma characterized by prominent mucus hypersecretion. PMID:23394251

    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. PMID:23602213

    Background Chest wall resection is a complicated treatment modality with significant morbidity. The purpose of this study is to report our experience with chest wall resections and reconstructions. Methods The records of all patients undergoing chest wall resection and reconstruction were reviewed. Diagnostic procedures, surgical indications, the location and size of the chest wall defect, performance of lung resection, the type of prosthesis, and postoperative complications were recorded. Results From 1997 to 2008, 162 patients underwent chest wall resection.113 (70%) of patients were male. Age of patients was 14 to 69 years. The most common indications for surgery were primary chest wall tumors. The most common localized chest wall mass has been seen in the anterior chest wall. Sternal resection was required in 22 patients, Lung resection in 15 patients, Rigid prosthetic reconstruction has been used in 20 patients and nonrigid prolene mesh and Marlex mesh in 40 patients. Mean intensive care unit stay was 8 days. In-hospital mortality was 3.7 % (six patients). Conclusions Chest wall resection and reconstruction with Bone cement sandwich with mesh can be performed as a safe and effective surgical procedure for major chest wall defects and respiratory failure is lower in prosthetic reconstruction patients than previously reported (6).

    Solar and atmospheric science radiometers, e.g. pyranometers, pyrheliometers, and photovoltaic cells are calibrated with traceability to a consensus reference, which is maintained by Absolute Cavity Radiometers (ACRs). The ACR is an open cavity with no window, developed to measure extended broadband direct solar irradiance beyond the ultraviolet and infrared bands below and above 0.2 micrometers and 50 micrometers, respectively. On the other hand, pyranometers and pyrheliometers are developed to measure broadband shortwave irradiance from approximately 0.3 micrometers to 3 micrcometers, while the present photovoltaic cells are limited to approximately 0.3 micrometers to 1 micrometers. The broadband mismatch of ACR versus such radiometers causes discrepancy in radiometers' calibration methods that has not been discussed or addressed in the solar and atmospheric science literature. Pyrgeometers are also used for solar and atmospheric science applications and calibrated with traceability to consensus reference, yet calibrated during nighttime only, because no consensus reference has yet been established for the daytime longwave irradiance. This poster shows a method to measure the broadband IR irradiance in the direct solar beam from 3 micrometers to 50 micrometers, as first step that might be used to help develop calibration methods to address the mismatch between broadband ACR and shortwave radiometers, and the lack of a daytime reference for pyrgeometers. The irradiance was measured from sunrise to sunset for 5 days when the sun disk was cloudless; the irradiance varied from approximately 1 Wm-2 to 16 Wm-2 for solar zenith angle from 80 degres to 16 degrees respectively; estimated uncertainty is 1.5 Wm-2.

    Background: Gynaecomastia is usually treated with liposuction or liposuction with excision of the glandular tissue. The type of surgery chosen depends on the grade of the condition. Objective: Because gynaecomastia is treated primarily as a cosmetic procedure, we aimed at reducing the invasiveness of the surgery. Materials and Methods: The technique complies with all recommended protocols for different grades of gynaecomastia. It uses liposuction, gland excision, or both, leaving only minimal post-operative scars. The use of cross-chest liposuction through incisions on the edge of the areola helps to get rid of all the fat under the areola without an additional scar as in the conventional method. Results: This is a short series of 20 patients, all with bilateral gynaecomastia (i.e., 40 breasts), belonging to Simon's Stage 1 and 2, studied over a period of 2 years. The average period of follow-up was 15 months. Post-operative complications were reported in only two cases, with none showing long-term complications or issues specifically due to the procedure. Conclusions : Cross-chest liposuction for gynaecomastia is a simple yet effective surgical tool in bilateral gynaecomastia treatment to decrease the post-operative scars. The use of techniques like incision line drain placement and post-drain removal suturing of wounds aid in decreasing the scar. PMID:21713166

    The call to the Emergency Medical Dispatch Centre is often a person's first contact with the health-care system in cases of acute illness or injury and acute chest pain is a common reason for calling. The aim was to illuminate how spouses to persons with acute chest pain experienced the alarm situation, the emergency call and the prehospital emergency care. Interviews were conducted with nineteen spouses. A phenomenological-hermeneutic approach was used for the analyses. The themes responsibility and uneasiness emerged as well as an overall theme of aloneness. Being a spouse to a person in need of acute medical and nursing assistance was interpreted as "Being responsible and trying to preserve life" and "Being able to manage the uneasiness and having trust in an uncertain situation." When their partners' life was at risk the spouses were in an escalating spiral of worry, uncertainty, stress, fear of loss, feeling of loneliness and desperation. They had to manage emotional distress and felt compelled to act to preserve life, a challenging situation. PMID:18929341

    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

    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.

Participants were progressed 64 people except 6 absentees among 70 people who agreed to participation with completing the CPR curriculum. In the classification of group in participants, the modified chest compression method was called as smartphone group (33 people). The standardized chest compression method was called as traditional group (31 people). The common equipments in both groups were used Manikin for practice and Manikin for evaluation. In the meantime, the smartphone group for application was utilized Android and iOS Operating System (OS) of 2 smartphone products (G, i). The measurement period was conducted from September 25th to 26th, 2012. Data analysis was used SPSS WIN 12.0 program. As a result of research, the proper compression depth (mm) was shown the proper compression depth (p< 0.01) in traditional group (53.77 mm) compared to smartphone group (48.35 mm). Even the proper chest compression (%) was formed suitably (p< 0.05) in traditional group (73.96%) more than smartphone group (60.51%). As for the awareness of chest compression accuracy, the traditional group (3.83 points) had the higher awareness of chest compression accuracy (p< 0.001) than the smartphone group (2.32 points). In the questionnaire that was additionally carried out 1 question only in smartphone group, the modified chest compression method with the use of smartphone had the high negative reason in rescuer for occurrence of hand back pain (48.5%) and unstable posture (21.2%).

    Background Management of acute respiratory tract infection varies substantially despite this being a condition frequently encountered in pediatric emergency departments. Previous studies have suggested that the use of antibiotics was higher when chest radiography was performed. However none of these analyses had considered the inherent indication bias of observational studies. Objective The aim of this work was to assess the relationship between performing chest radiography and prescribing antibiotics using a propensity score analysis to address the indication bias due to non-random radiography assignment. Methods We conducted a prospective study of 697 children younger than 2 years of age who presented during the winter months of 2006–2007 for suspicion of respiratory tract infection at the Pediatric Emergency Department of an urban general hospital in France (Paris suburb). We first determined the individual propensity score (probability of having a chest radiography according to baseline characteristics). Then we assessed the relation between radiography and antibiotic prescription using two methods: adjustment and matching on the propensity score. Results We found that performing a chest radiography lead to more frequent antibiotic prescription that may be expressed as OR = 2.3, CI [1.3–4.1], or as an increased use of antibiotics of 18.6% [0.08–0.29] in the group undergoing chest radiography. Conclusion Chest radiography has a significant impact on the management of infants admitted for suspicion of respiratory tract infection in a pediatric emergency department and may lead to unnecessary administration of antibiotics.

As a first step toward this goal, the paper presents a novel approach for detecting lungs and ribs in chest radiographs. The approach is a unified method combining two detection schemes resulting in reduced cost. The novelty of our approach lies on the fact that instead of using pixel-wise techniques exclusively we used region-based features computed as wavelet features that take into consideration the orientation of anatomic structures. Initial results are described. Next steps include classification of non-rib lung regions for radiographic patterns suggesting tuberculosis infection. PMID:22256142

    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.

  17. Pleural fluids associated with chest infection.

    Quadri, Amal; Thomson, Anne H

    Pleural effusions are commonly associated with pneumonias and a small number of these progress to empyema. An understanding of the physiology and pathophysiology of pleural fluid aids the clinician in the management of empyema. There remains much debate about the optimal treatment of empyema in children. Early recognition of the condition is important since delayed therapy may result in unnecessary morbidity. Conventional management with high dose parenteral antibiotics and chest tube drainage remains the mainstay of therapy. However, this treatment modality may fail if the pleural fluid becomes viscous and loculated and, therefore, a more aggressive approach is required. Intrapleural fibrinolytic therapy has been shown to decrease the length of hospital stay and may reduce the need for surgical intervention. The prognosis in children with parapneumonic empyema is excellent with the vast majority retaining normal lung function at long term follow-up.

    Tracheobronchial avulsion resulting from blunt trauma is a very rare and serious condition, mostly due to high-speed traffic crashes. In this article, we briefly report the case of an 18-year-old man who was injured in a car accident and because of massive persistent air leakage (despite appropriate chest tube drainage), deemed to have a deep tracheobronchial injury. Due to a rapid drop in the patient's O2 saturation, he underwent an anterolateral thoracotomy. Endotracheal intubation was performed under direct visualization. The right mainstem bronchus was disrupted from the carina with a 1.5-cm stump remaining on the carina, and the remainder was crushed to the origin of the right superior lobe bronchus. Hence, a right superior lobectomy was performed and the postoperative course was uneventful. PMID:26157657

    Chest tuberculosis (CTB) is a widespread problem, especially in our country where it is one of the leading causes of mortality. The article reviews the imaging findings in CTB on various modalities. We also attempt to categorize the findings into those definitive for active TB, indeterminate for disease activity, and those indicating healed TB. Though various radiological modalities are widely used in evaluation of such patients, no imaging guidelines exist for the use of these modalities in diagnosis and follow-up. Consequently, imaging is not optimally utilized and patients are often unnecessarily subjected to repeated CT examinations, which is undesirable. Based on the available literature and our experience, we propose certain recommendations delineating the role of imaging in the diagnosis and follow-up of such patients. The authors recognize that this is an evolving field and there may be future revisions depending on emergence of new evidence. PMID:26288514

    Ten radiologists were shown a series of 10 normal and 10 abnormal chest films under two viewing conditions: a 0.2-second flash and unlimited viewing time. The results were compared in terms of verbal content, diagnostic accuracy, and level of confidence. The overall accuracy was surprisingly high (70% true positives) considering that no search was possible. Performance improved as expected with free search (97% true positives). These data support the hypothesis that visual search begins with a global response that establishes content, detects gross deviations from normal, and organizes subsequent foveal checking fixations to conduct a detailed examination of ambiguities. The total search strategy then consists of an ordered sequence of interspersed global and checking fixations. PMID:125436

    In the recent years, with the development of ultrafast sequences, magnetic resonance imaging (MRI) has been established as a valuable diagnostic modality in body imaging. Because of improvements in speed and image quality, MRI is now ready for routine clinical use also in the study of pulmonary diseases. The main advantage of MRI of the lungs is its unique combination of morphological and functional assessment in a single imaging session. In this article, the authors review most technical aspects and suggest a protocol for performing chest MRI. The authors also describe the three major clinical indications for MRI of the lungs: staging of lung tumors; evaluation of pulmonary vascular diseases; and investigation of pulmonary abnormalities in patients who should not be exposed to radiation.

    Diagnosis of acute lung disease is a daily challenge for radiologists working in acute-care areas. It is generally based on the results of chest radiography performed under technically unfavorable conditions. Computed tomography (CT) is undoubtedly more accurate in these cases, but it cannot always be performed on critically ill patients who need continuous care.The use of thoracic ultrasonography (US) has recently been proposed for the study of acute lung disease. It can be carried out rapidly at the bedside and does not require any particularly sophisticated equipment. This report analyzes our experience with chest sonography as a supplement to chest radiography in an Emergency Radiology Unit. We performed chest sonography - as an adjunct to chest radiography - on 168 patients with acute chest pathology. Static and dynamic US signs were analyzed in light of radiographic findings and, when possible, CT. The use of chest US improved the authors' ability to provide confident diagnoses of acute disease of the chest and lungs.

  7. Management of chest drainage tubes after lung surgery.

    PubMed

    Satoh, Yukitoshi

    2016-06-01

    Since chest tubes have been routinely used to drain the pleural space, particularly after lung surgery, the management of chest tubes is considered to be essential for the thoracic surgeon. The pleural drainage system requires effective drainage, suction, and water-sealing. Another key point of chest tube management is that a water seal is considered to be superior to suction for most air leaks. Nowadays, the most common pleural drainage device attached to the chest tube is the three-bottle system. An electronic chest drainage system has been developed that is effective in standardizing the postoperative management of chest tubes. More liberal use of digital drainage devices in the postoperative management of the pleural space is warranted. The removal of chest tubes is a common procedure occurring almost daily in hospitals throughout the world. Extraction of the tube is usually done at the end of full inspiration or at the end of full expiration. The tube removal technique is not as important as how it is done and the preparation for the procedure. The management of chest tubes must be based on careful observation, the patient's characteristics, and the operative procedures that had been performed. PMID:27048219

    Background: Management of complex thoracic defects post tumor extipiration is challenging because of the nature of pathology, the radical approach, and the insertion of prosthetic material required for biomechanical stability. Wound complications pose a significant problem that can have detrimental effect on patient outcome. The authors outline an institutional experience of a multidisciplinary thoracic oncoplastic approach to improve outcomes. Methods: Prospectively collected data from 71 consecutive patients treated with chest wall resection and reconstruction were analyzed (2009–2015). The demographic data, comorbidities, operative details, and outcomes with special focus on wound infection were recorded. All patients were managed in a multidisciplinary approach to optimize perioperative surgical planning. Results: Pathology included sarcoma (78%), locally advanced breast cancer (15%), and desmoids (6%), with age ranging from 17 to 82 years (median, 42 years) and preponderance of female patients (n = 44). Chest wall defects were located anterior and anterolateral (77.5%), posterior (8.4%), and apical axillary (10%) with skeletal defect size ranging from 56 to 600 cm2 (mean, 154 cm2). Bony reconstruction was performed using polyprolene mesh, methyl methacrylate prosthesis, and titanium plates. Soft tissue reconstructions depended on size, location, and flap availability and were achieved using regional, distant, and free tissue flaps. The postoperative follow-up ranged from 5 to 70 months (median, 32 months). All flaps survived with good functional and aesthetic outcome, whereas 2 patients experienced surgical site infection (2.8%). Conclusions: Multidisciplinary thoracic oncoplastic maximizes outcome for patients with large resection of chest wall tumors with reduction in surgical site infection and wound complications particularly in association with rigid skeletal chest wall reconstruction.

    GPIPS will be completed in 2013, and the first data release (DR1) took place in August 2012 (see poster by L. Cashman). All of the 3,237 independent field observations, designed for the 10x10 arcmin Mimir instrument field of view, have been obtained, though a small number are being re-observed to meet our 2 arcsec seeing criterion. GPIPS data products include catalogs of stellar polarizations (POLCATs), catalogs of stellar photometry in the H-band (PHOTCATs), and deep co-added images for each field. The images for the entire 76 square degree region of the northern Galactic midplane surveyed have been mosaicked to create a large-format poster, which can be found elsewhere in the room. On the poster, data from the POLCATs are overlaid as polarization vectors, or circled stars for those exhibiting significant upper limits. Comparisons with other key data sets for correlative studies, such as the Galactic Ring Survey (Jackson et al. 2006), 2MASS (Skrutskie et al. 2006), WISE (Wright et al. 2010), the Bolocam Galactic Plane Survey (BGPS; Aguirre et al. 2011), GLIMPSE (Benjamin et al. 2003), and MIPSGAL (Mizuno et al. 2008) are also shown. Access to released GPIPS data is currently through our web server (gpips0.bu.edu), with planned upgrades to VO compliance and mirroring from other sites. This work is partially supported by NSF/MPS grants AST 06-07500 and AST 09-07790.

    Purpose Standardization of imaging obtained in children with neuroblastoma is not well established. This study examines chest CT in pediatric patients with high-risk neuroblastoma. Methods Medical records and imaging from 88 patients with high-risk neuroblastoma, diagnosed at St. Jude Children's Research Hospital between January, 2002 and December, 2009, were reviewed. Surveillance imaging was conducted through 2013. Ten patients with thoracic disease at diagnosis were excluded. Event free survival (EFS) and overall survival (OS) were estimated. Size specific dose estimates for CT scans of the chest, abdomen, and pelvis were used to estimate absolute organ doses to 23 organs. Organ dosimetry was used to calculate cohort effective dose. Results The 5 year OS and EFS were 51.9%±6.5% and 42.6%±6.5%, respectively. Forty-six (58.9%) patients progressed/recurred and 41 (52.6%) died of disease. Eleven patients (14%) developed thoracic disease progression/recurrence identified by chest CT (1 paraspinal mass, 1 pulmonary nodules, and 9 nodal). MIBG (metaiodobenzylguanidine) scans identified thoracic disease in 6 patients. Five of the 11 had normal chest MIBG scans; 3 were symptomatic and 2 were asymptomatic with normal chest MIBG scans but avid bone disease. The estimated radiation dose savings from surveillance without CT chest imaging was 42%, 34% when accounting for modern CT acquisition (2011-13). Conclusions Neuroblastoma progression/recurrence in the chest is rare and often presents with symptoms or is identified using standard non-CT imaging modalities. For patients with non-thoracic high-risk neuroblastoma at diagnosis, omission of surveillance chest CT imaging can save 35-42% of the radiation burden without compromising disease detection.

    Chest fat estimation is important for identifying high-risk lung transplant candidates. In this paper, an approach to chest fat quantification based on a recently formulated concept of standardized anatomic space (SAS) is presented. The goal of this paper is to seek answers to the following questions related to chest fat quantification on single slice versus whole volume CT, which have not been addressed in the literature. What level of correlation exists between total chest fat volume and fat areas measured on single abdominal and thigh slices? What is the anatomic location in the chest where maximal correlation of fat area with fat volume can be expected? Do the components of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) have the same area-to-volume correlative behavior or do they differ? The SAS approach includes two steps: calibration followed by transformation which will map the patient slice locations non-linearly to SAS. The optimal slice locations found for SAT and VAT based on SAS are different and at the mid-level of the T8 vertebral body for SAT and mid-level of the T7 vertebral body for VAT. Fat volume and area on optimal slices for SAT and VAT are correlated with Pearson correlation coefficients of 0.97 and 0.86, respectively. The correlation of chest fat volume with abdominal and thigh fat areas is weak to modest.

    Background Acute chest pain is a major health problem all over the western world. Active approaches are directed towards diagnosis and treatment of potentially life threatening conditions, especially acute coronary syndrome/ischemic heart disease. However, according to the literature, chest pain may also be due to a variety of extra-cardiac disorders including dysfunction of muscles and joints of the chest wall or the cervical and thoracic part of the spine. The diagnostic approaches and treatment options for this group of patients are scarce and formal clinical studies addressing the effect of various treatments are lacking. Methods/Design We present an ongoing trial on the potential usefulness of chiropractic diagnosis and treatment in patients dismissed from an acute chest pain clinic without a diagnosis of acute coronary syndrome. The aims are to determine the proportion of patients in whom chest pain may be of musculoskeletal rather than cardiac origin and to investigate the decision process of a chiropractor in diagnosing these patients; further, to examine whether chiropractic treatment can reduce pain and improve physical function when compared to advice directed towards promoting self-management, and, finally, to estimate the cost-effectiveness of these procedures. This study will include 300 patients discharged from a university hospital acute chest pain clinic without a diagnosis of acute coronary syndrome or any other obvious cardiac or non-cardiac disease. After completion of the clinic's standard cardiovascular diagnostic procedures, trial patients will be examined according to a standardized protocol including a) a self-report questionnaire; b) a semi-structured interview; c) a general health examination; and d) a specific manual examination of the muscles and joints of the neck, thoracic spine, and thorax in order to determine whether the pain is likely to be of musculoskeletal origin.

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

    Symptomatic thoracic disc herniation is clinically rare. There are few cases of disc herniation of the thoracic spine in top athletes described in the literature. We herein present a rare case of chest wall pain due to thoracic disc herniation in a professional baseball pitcher. A 30-year-old, left-handed pitcher complained of left-sided chest wall pain in the region of his lower ribs during a game. Neurological examination revealed hypoesthesia of the left side of the chest at the level of the lower thoracic spine. Magnetic resonance imaging (MRI) of the thoracic spine showed a left-sided paramedian disc herniation at the T9-T10 level. The player was initially prescribed rest, administration of pregabalin (150 mg twice a day), and subsequent physical rehabilitation. He was able to resume full training and pitching without medication 6 months after the onset. A follow-up MRI of the thoracic spine showed a reduction in the size of the herniated disc compared to the initial findings. Though relatively rare, thoracic disc herniation should be considered in cases of chest wall pain in athletes.

    Symptomatic thoracic disc herniation is clinically rare. There are few cases of disc herniation of the thoracic spine in top athletes described in the literature. We herein present a rare case of chest wall pain due to thoracic disc herniation in a professional baseball pitcher. A 30-year-old, left-handed pitcher complained of left-sided chest wall pain in the region of his lower ribs during a game. Neurological examination revealed hypoesthesia of the left side of the chest at the level of the lower thoracic spine. Magnetic resonance imaging (MRI) of the thoracic spine showed a left-sided paramedian disc herniation at the T9-T10 level. The player was initially prescribed rest, administration of pregabalin (150 mg twice a day), and subsequent physical rehabilitation. He was able to resume full training and pitching without medication 6 months after the onset. A follow-up MRI of the thoracic spine showed a reduction in the size of the herniated disc compared to the initial findings. Though relatively rare, thoracic disc herniation should be considered in cases of chest wall pain in athletes. PMID:26983590

    Measurement of chest wall displacement is an important approach for measuring mechanics of chest wall, which has considerable significance for assessing respiratory system and diagnosing pulmonary diseases. However, existing optical methods for measuring chest wall displacement are inconvenient for some specific patients such as the female patients and the patients with bandaged chest. In this letter, we proposed a method for measuring chest wall displacement based on terahertz wave and established corresponding mathematic model and set up a terahertz measurement system. The main advantages of this method are that it can measure the chest wall displacement of the subjects without taking off clothes or arranging any markers. To validate this method and assess the performance of the terahertz system, in vitro, the displacement of a water module driven by a linear guide rail was measured by the terahertz system and compared with the actual displacement of the water module. The results showed that the waveforms measured with two methods have a good agreement, and the relative error is less than 5% and sufficiently good for measurement demands. In vivo, the synchronous experiment was performed on five human volunteers with the terahertz system and a respiratory belt transducer. The results demonstrate that this method has good performance and promising prospects for measuring chest wall displacement.

  12. Use of the omentum in chest-wall reconstruction

    Increased use of the omentum in chest-wall reconstruction has paralleled the refinement of anatomic knowledge and the development of safe mobilization techniques. Important anatomic points are the omental attachments to surrounding structures, the major blood supply from the left and right gastroepiploic vessels, and the collateral circulation via the gastroepiploic arch and Barkow's marginal artery. Mobilization of the omentum to the thorax involves division of its attachments to the transverse colon and separation from the greater curvature to fabricate a bipedicled flap. Most anterior chest wounds and virtually all mediastinal wounds can be covered with the omentum based on both sets of gastroepiploic vessels. The arc of transposition is increased when the omentum is based on a single pedicle, allowing coverage of virtually all chest-wall defects. The final method of increasing flap length involves division of the gastroepiploic arch and reliance on Barkow's marginal artery as collateral circulation to maintain flap viability. With regard to chest-wall reconstruction, we have included the omentum in the armamentarium of flaps used to cover mediastinal wounds. The omentum is our flap of choice for the reconstruction of most radiation injuries of the chest wall. The omentum may also be used to provide protection to visceral anastomoses, vascular conduits, and damaged structures in the chest, as well as to cover defects secondary to tumor excision or trauma. In brief, the omentum has proved to be a most dependable and versatile flap, particularly applicable to chest-wall reconstruction.

    The climate model of the Goddard Institute for Space Studies (GISS GCM) has been used to project the influence of increasing concentrations of greenhouse gases on the future global climate. New parameterizations for the GISS GCM are being developed to improve its depiction of current climate scenarios and to make it more sensitive to the variability of external forcing mechanisms such as sea-surface temperatures (SST), atmospheric aerosols and constituent trace gases. The new moist convection scheme makes cumulus fluxes proportional to vertical thermal instability and computes convective-scale downdrafts whose effect is to prevent excessive drying of the boundary layer by compensating subsidence. The physically-based ground hydrology component improves the land surface sensible and latent heat calculations by explicitly considering transpiration, evaporation from intercepted precipitation, evaporation from bare soil, infiltration, soil water flow and runoff. The revised planetary boundary layer uses a more valid physical model than previously to obtain more realistic near-surface winds and energy budgets. Preliminary results with newer versions of the GCM include a better seasonal migration of the ITCZ and more realistic tropical winds. One of our approaches to model validation is the evaluation of runs forced by globally observed sea-surface temperatures. The presentation will show how model improvements increase the quality of simulated interannual variations in global circulation and tropical rainfall.

    Pediatric and adult ATD's are key tools for the development of motor vehicle crash safety systems. Previous researchers developed size-based scaling methods to adapt blunt chest impact data from adult post-mortem human subjects (PMHS) for pediatric ATD chests design requirements, using skull or femur elastic modulus ratios to estimate the change in whole chest stiffness during maturation. Recently, the mechanics of chest compression during cardiopulmonary resuscitation (CPR) of patients spanning the pediatric and elderly ages have been reported. Our objective was to integrate these pediatric and adult chest stiffness data from CPR into the established scaling methods to 1) compare new CPR-based and existing pediatric ATD chest biofidelity response requirements and 2) develop new CPR-based corridors for ages 12 and 20 years, which do not currently exist. Compared to the current 6-year-old ATD corridor, the maximum force of the CPR-based 6-year-old corridor was 7% less and the maximum displacement was 8% greater, indicating a softer chest. Compared to the current 10-year-old corridor, the new 10-year-old corridor peak force was 12% higher and the peak displacement was 11% smaller, suggesting a stiffer chest. The 12-year-old corridor developed in this paper was 10% higher in maximum force and 4% lower in maximum displacement compared with the adult 5(th) percentile female (AF05). Finally, the 20-year-old 50(th) percentile male (AM50(20)) corridor was 24% higher in maximum force and 19% lower in maximum displacement than 63-year old 50(th) percentile adult male (AM50(63)) corridor, suggesting a stiffer chest. We consider all the new corridors preliminary, as data collection is ongoing for CPR subjects under age 8 years and in the young and middle adult age ranges.

    The results obtained from two radiological methods of determining total lung capacity (TLC) (Kovach's parabo oid and Barnhard's ellipsoid) were compared with those obtained with the body plethysmograph. Determinations of TLC were made in four groups of subjects: group 1 consisted of 26 miners most of whom had simple pneumoconiosis; group 2 consisted of 12 normal subjects; group 3 consisted of eight subjects who had a variety of chest disease, but with no demonstrable parenchymal or pleural opacification; and group 4 consisted of 19 subjects with miscellaneous diseases, all showing demonstrable infiltration or opacification. The values obtained by the method of Kovach and his colleagues often differed markedly from the plethysmographic determinations, and it became apparent that this method was not sufficiently accurate. On the other hand, the technique of Barnhard and his colleagues gave results that were essentially similar to, and as far as we can say interchangeable with, those obtained by the body plethysmograph in groups 1, 2, and 3. In subjects with marked pulmonary opacification or infiltration, the disparity between Barnhard's method and the plethysmograph tended to be more sizeable. It was concluded that Barnhard's method for determining total lung capacity is accurate and could be applied to epidemiological surveys. PMID:5489177

    The report demonstrates the feasibility of using a computer for automated interpretation of chest radiographs for pneumoconiosis. The primary goal of this project was to continue testing and evaluating the prototype system with a larger set of films. After review of the final contract report and a review of the current literature, it was clear that several modifications to the prototype system were needed before the project could continue. These modifications can be divided into two general areas. The first area was in improving the stability of the system and compensating for the diversity of film quality which exists in films obtained in a surveillance program. Since the system was to be tested with a large number of films, it was impractical to be extremely selective of film quality. The second area is in terms of processing time. With a large set of films, total processing time becomes much more significant. An image display was added to the system so that the computer determined lung boundaries could be verified for each film. A film handling system was also added, enabling the system to scan films continuously without attendance.

    Eosinophilic fasciitis (EF) is an unusual disorder characterized by diffuse skin thickening and induration due to inflammation within the deep fascia; visceral involvement is generally mild or absent. A patient with biopsy-proved EF developed progressive respiratory limitation. Physical examination revealed marked induration of the thoracic integument with a severely limited chest wall excursion. Total lung capacity was 62 percent of predicted with a normal corrected Dco and maximal inspiratory force; a chest computed tomogram with thin sections showed no evidence of parenchymal lung disease. Extrapulmonary thoracic restriction ("hidebound chest") has not been previously reported to complicate EF.

    [Purpose] The aim of this study was to examine the effect of chest expansion resistance exercises (CERE) on chest expansion, maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP) in elderly people with inspiratory muscle weakness. [Subjects] Thirty elderly people with inspiratory muscle weakness (MIP < 80% of the predicted value) were randomly and equally assigned to a chest expansion resistance exercise (CERE) group, core conditioning exercise (CCE) group, and control group. [Methods] The intervention was applied to the CERE group and CCE group five times per week, 30 minutes each time, for six weeks. A tapeline was used to measure upper and lower chest expansion. MIP and MEP before and after the intervention were measured and compared. [Results] There was significant improvement in upper and lower chest expansion and MIP after the intervention in both the CERE group and the CCE group, whereas the control group did not show any significant difference. MEP did not significantly change in any of the three groups after the intervention. [Conclusion] The CERE group underwent greater changes than the CCE group, which proves that the CERE is more effective for improving elderly people's chest expansion capacity and MIP in elderly people. Therefore, application of the CERE by therapists is recommended if the environment and conditions are appropriate for enhancement of chest expansion capacity and MIP in elderly people.

    Although from a respiratory point of view, compartmental volume change or lack of it is the most crucial variable, it has not been possible to measure the volume of chest wall compartments directly. Recently we developed a new method based on a optoelectronic motion analyzer that can give the three-dimensional location of many markers with the temporal and spatial accuracy required for respiratory measurements. Marker's configuration has been designed specifically to measure the volume of three chest wall compartments, the pulmonary and abdominal rib cage compartments and the abdomen, directly. However, it can not track the exact border between the two rib cage compartments (pulmonary and abdominal) which is determined by the cephalic extremity of the area of apposition of the diaphragm to the inner surface of the rib cage, and which can change systematically as a result of disease processes. The diaphragm displacement can be detected by ultrasonography. In the present study, we propose an integrated system able to investigate the relationships between external (chest wall) and internal (diaphragm) movements of the different respiratory structures by simultaneous external imaging with the optoelectronic system combined with internal kinematic imaging using ultrasounds. 2D digitized points belonging to the lower lung margin, taken from ultrasonographic views, are mapped into the 3D space, where chest wall markers are acquired. Results are shown in terms of accuracy of 3D probe location, relative movement between the probe and the body landmarks, dynamic relationships between chest wall volume and position of the diaphragm during quiet breathing, slow inspirations, relaxations and exercise.

    This study presents a case series of suicides carried out by self-inflicted gunshot wounds to the chest-a relatively uncommon means of suicide. The retrospective autopsy study performed included all cases of single suicidal gunshot injuries to the chest during a 20-year period and which were committed by the use of a handgun. The sample included 67 deceased persons that were an average of 44.4 ± 19.1 years old (range, 12-89 years; 58 men and 9 women). The most common region of the entrance wound was the left side of the chest (54/67), followed by the sternum (10/67), and the right side of the chest (3/67). For 9 subjects, the range of fire could not be determined, as well as whether the shot went through their clothing. In the remaining 58 subjects, only contact or near-contact wounds were found. Of the 58, only 3 subjects had their clothing removed between the chest wall and the muzzle. Three directions of the internal bullet paths were those most frequently found: downward right-to-left (27/67), downward left-to-right (20/67), and downward parallel (10/67) (χ = 101.045, P = 0.000). Also, most bullet paths were directed downward (57/67, χ = 32.970, P = 0.000). The most frequently injured organ was the heart (47/67), and the immediate causes of death were exsanguination (49/67), heart disruption (14/67), and tamponade (4/67).

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

It is characterized by hypoplasia of the breast and nipple, subcutaneous tissue shortages, lack of the costosternal portion of the pectoralis major muscle and associated alterations of the fingers on the same side. Corrective treatment of the chest and soft tissue abnormalities in Poland syndrome varies according to different authors. We report the case of a 17-year-old adolescent who underwent chest wall reconstruction with a methyl methacrylate prosthesis. This surgical procedure is recommended for large anterior chest wall defects, and it prevents paradoxical movement. Moreover it provides for individual remodeling of the defect depending on the shape of the patient's chest. PMID:23453291

    The flat-panel detector (FPD) has been introduced into clinical practice. A modified FPD, which has the ability to obtain dynamic chest radiographs, was introduced into our hospital, and clinical testing is ongoing. Both the inspiratory and expiratory phases have to be included in dynamic chest radiographs. The purpose of this study was to investigate the most appropriate chest radiography signal for observation of the respiratory process. We prepared ten protocol patterns that differed in terms of respiratory phase at X-ray exposure, exposure duration, and signal multiplicity. We also performed preliminary experiments and administered several questionnaires to ten volunteers. The volunteers breathed according to vocal and visual signals, and their respiratory waves were recorded by spirometer. The most appropriate protocol was similar to the method used for conventional chest radiography. PMID:12960952

    Background: The safe insertion of a chest drain is a skill doctors across specialties require. Incorrect placement can lead to significant morbidity and even mortality. Methods: This audit surveyed junior doctors working in a teaching hospital about their specialty and level of experience with intercostal drains. They were then asked to mark on a photograph where they would insert a chest drain for a pneumothorax in a non-emergency situation. Results: Of the 55 junior doctors surveyed, 45% were outside the safe area of chest drain insertion as defined by the British Thoracic Society. The most common error was a choice of insertion site too low (24%). Conclusions: In this audit 45% of juniors surveyed would have placed a chest drain outside the safe triangle recommended by the British Thoracic Society. The common mistake of a choice of insertion site too low should be discussed in postgraduate teaching programmes. PMID:15998822

    Tuberculosis (TB) is a major public health problem worldwide, and highly prevalent in developing countries. According to the World Health Organization (WHO), over 95% of TB deaths occur in low- and middle- income countries that often have under-resourced health care systems. In an effort to aid population screening in such resource challenged settings, the U.S. National Library of Medicine has developed a chest X-ray (CXR) screening system that provides a pre-decision on pulmonary abnormalities. When the system is presented with a digital CXR image from the Picture Archive and Communication Systems (PACS) or an imaging source, it automatically identifies the lung regions in the image, extracts image features, and classifies the image as normal or abnormal using trained machine-learning algorithms. The system has been trained on adult CXR images, and this article presents enhancements toward including pediatric CXR images. Our adult lung boundary detection algorithm is model-based. We note the lung shape differences during pediatric developmental stages, and adulthood, and propose building new lung models suitable for pediatric developmental stages. In this study, we quantify changes in lung shape from infancy to adulthood toward enhancing our lung segmentation algorithm. Our initial findings suggest pediatric age groupings of 0 - 23 months, 2 - 10 years, and 11 - 18 years. We present justification for our groupings. We report on the quality of boundary detection algorithm with the pediatric lung models.

    A computer-aided diagnosis scheme for the detection of interstitial disease in standard digital posteroanterior (PA) chest radiographs is presented. The detection technique is supervised-manually labelled data should be provided for training the algorithm-and fully automatic, and can be used as part of a computerized analysis scheme for X-ray lung images. Prior to the detection, a segmentation should be performed which delineates the lung field boundaries. Subsequently, a quadratic decision rule is employed for every pixel within the lung fields to associate with each pixel a probabilistic measure indicating interstitial disease. The locally obtained per-pixel probabilities are fused to a single global probability indicating to what extent there is interstitial disease present in the image. Finally, a threshold on this quantity classifies the image as containing interstitial disease or not. The probability combination scheme presented utilizes the quantiles of the local posterior probabilities to fuse the local probability into a global one. Using this nonparametric technique, reasonable results are obtained on the interstitial disease detection task. The area under the receiver operating characteristic equals 0.92 for the optimal setting.
