1/27. Heart disease vis-a-vis trauma.Virtually all forensic experts deal not only with criminal, suspicious, accidental and suicidal deaths, but are also confronted with a wide range of deaths where a significant natural element is revealed at autopsy. The assaulted victim that dies suddenly or unexpectedly from a stroke during or immediately succeeding the receipt of some non-fatal injuries, or otherwise suffers a clinically unexplained death, can pose far greater difficulties over causation than a gun-shot or a stabbing. This paper presents an analysis of the problem and an approach for determining the cause of death in cases of concurrent trauma with heart disease, and in cases with a substantial natural element of disease but exclusion of trauma. Relevant cases with history, autopsy findings, histopathological findings and toxicological findings are presented in order to illustrate the issue from a practical angle.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
2/27. myocardial infarction as a complication of injury.BACKGROUND: MI is a rare complication of trauma. We anticipate that the aging of the population and the concomitant rise in geriatric trauma will result in an increase in acute illnesses of the elderly (such as MI) complicating recovery from injury. The purpose of this article is to define the presentation of MI in the immediate postinjury period. STUDY DESIGN: medical records of all trauma patients in whom MI developed during their hospitalizations at a single Level I trauma center, the Barnes Hospital/washington University Medical Center, between 1990 and 1999 were screened through the trauma registry. Nineteen patients with possible postinjury MI were identified. Of these, five had bona fide cases of postinjury MI, five had ambiguity about whether MI preceded or followed trauma, one had an MI resulting in trauma, and eight were excluded because they did not meet strict diagnostic criteria for MI. RESULTS: The five patients with posttraumatic MI were older than the general trauma population with ages ranging from 51 to 81 years (mean /- SD = 72 /- 14 years). Each had preexisting medical illnesses, some of which are recognized to predispose to coronary artery disease. There were no identifiable precipitants other than the recent injury. Importantly, only one of the five patients had chest pain as a presenting symptom and each of the five cases was complicated by acute congestive heart failure. CONCLUSIONS: MI remains a rare but important complication of injury and may increase owing to the changing demographics of trauma victims. methods for thorough history-gathering to identify preexisting conditions, for early hemodynamic monitoring and anticoagulation for MI in the setting of trauma, and for identifying preexisting conditions should be defined. The presentation of MI in the setting of injury is atypical and complications are frequent.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
3/27. Transcatheter closure of a posttraumatic ventricular septal defect with an Amplatzer occluder device.Cardiac traumatization may lead to severe complications. Transcatheter closure of a postraumatic ventricular septal defect (VSD) was successfully done using an Amplatzer septal occluder in a man who had previously undergone surgery for myocardial fissure and mitral valve dysfunction. In selected cases, the percutaneous approach may be a valuable option to close muscular VSDs.- - - - - - - - - - ranking = 0.22149551905167keywords = valve (Clic here for more details about this article) |
4/27. Constraints and heroes.A story, perhaps apocryphal, is told about the united states surgical team which pioneered the first artificial heart procedure. It is said that the team received a number of telephone calls from people around the country who, worried about the ailing heart recipient, offered to donate to him their own hearts. When the surgical team, justifiably curious, sent psychiatrists to examine these donors, they found to their surprise that many of the donors were rational, competent, sincere, and fully aware that as a consequence of donating their hearts they would die....My concerns here will be threefold. First, I want to add some substance to the widely-held intuition that there is something morally objectionable about a physician participating in procedures which put even a willing subject at risk. In so doing, I want to explore the larger question of why such a puzzle arises -- why physicians, and many others, find it morally objectionable to help someone do something which all agree to be heroic. Finally, I will start by examining some ways of framing the issue, widely employed in medical ethics, which I believe are simply wrong. This sort of puzzle is much more interesting than proponents of these standard arguments would have us believe, and it illustrates some larger points about morality which are often overlooked.- - - - - - - - - - ranking = 4keywords = heart (Clic here for more details about this article) |
5/27. diving-related fatalities caused by underwater explosions: a report of two cases.The authors report two cases of diving-related water blast with fatal outcome resulting from nearby underwater explosions. water blast with fatal outcome almost exclusively occurs in wars at sea. Underwater explosions are extremely rare in diving because of the limited exposure. Forensic findings in both cases reported included expected injuries to gas-filled organs such as the middle ear, lungs, and intestine; some rarely described injuries such as rupture of the liver, spleen, and kidneys; and also some lesions that were not found in a search of the literature: rupture of the heart and contusion of the hypophysis. Injuries caused by fatal underwater explosions should be carefully evaluated in forensic medicine to provide data that may support a criminal investigation.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
6/27. Prehospital rounds. The quick stop.The coroner's post-mortem examination revealed a tom aorta. This case illustrates that although a patient may appear stable, a major catastrophic event may nonetheless be taking place. How many times have we responded to MVAs similar to the one described here and seen those involved deny injuries? We carry a higher suspicion of aortic injury after someone has been ejected from a vehicle or involved in a high-speed crash. That's not always the case, however, and understanding how internal organs respond to high-speed impacts is crucial. Damage to the aorta may result after a sudden deceleration injury of any type: a fall, vehicle crash or violence. The most common forms of traumatic aortic injury occur where the aorta is "tethered" in place: at its intersection with the heart and at its distal portion just beneath the left subclavian artery near the ligamenta arteriosum. Approximately 80% of patients with aortic injury die at the scene. The injury may be hidden in the other 20%, but they have the potential to rapidly deteriorate and die. Those who survive typically are at a trauma center and are cared for by providers who have a suspicion of the injury. A high index of suspicion should be maintained on all rapid-deceleration injuries and with patients who experience chest pain, dyspnea, a difference in pressure between the upper and lower extremities, and paralysis. paralysis can occur when aortic injury cuts off blood supply [table: see text] to the spinal cord. The spinal cord obtains its blood supply from arteries coming directly off the aorta, and a torn aorta can shear off these vessels, leaving the spinal cord to infarct and the patient to lose all distal function. When a victim sustains a sudden-deceleration injury to the chest, signs of aortic injury should be sought. It is imperative to maintain a high index of suspicion throughout patient care and be aware that although a patient may appear to be quite stable, the reality might be otherwise, and rapid transport to a trauma center will be necessary to save their life.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
7/27. An unusual occupational accident: fall into a sewage plant tank with lethal outcome.Occupational accidents, often presenting with lethal outcomes, are a rarely reported issue in forensic literature. However, these incidents are part of medicolegal casework with special regard to reconstruction, liabilities and insurance law-related issues, respectively. We report on a lethal occupational accident in a metropolitan sewage plant. When performing routine controls, a technician fell into an overflow sewer and was immediately pulled into a 30 cm diameter drain. Rescue efforts were initiated immediately, but had to be terminated due to gas warning. Rescue teams continued the search, however, the body remained undiscoverable. Forty-eight hours later, the cadaver was found in an adjacent digester tank, from where it was finally rescued. It was concluded, that the body had been transported between the overflow sewer and the digester tank through a 120 m pipeline with several 90 degrees bendings and branch connections with a minimum diameter of 25 cm at the discharge valve. On medicolegal examination, the cadaver showed marked signs of advanced decomposition caused by anaerobic microorganisms in the 37 degrees C biomass environment. Moreover, as a consequence of the passage of the pipeline system, signs of massive trauma (several comminuted and compound fractures) were disclosed at autopsy. To us, this is the first report on a lethal occupational accident in a sewage plant; our observations demonstrate the rapid progress of putrefaction in a warm anaerobic bacterial environment and the massive trauma sustained.- - - - - - - - - - ranking = 0.22149551905167keywords = valve (Clic here for more details about this article) |
8/27. The world's first automobile fatality.The first recorded automobile fatality occurred in a small town in the Irish Midlands in 1869. Mary Ward, a celebrated microscopist, artist, astronomer and naturalist, fell from a steam carriage and died after crush injuries from its heavy iron wheels. The story of first automobile fatality characterizes the individual tragedy that is each premature death. It also illuminates the story of a remarkable Victorian scientific family. Among their many achievements was the building of a reflector telescope in the heart of rural ireland that was the largest in the world for 74 years.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
9/27. Comparative alcohol concentrations in blood and vitreous fluid with illustrative case studies.The toxicology Bureau of the new mexico Department of health performs drug and alcohol testing on approximately 2800 medical examiner cases each year across the entire state. Although blood is usually the preferred specimen for alcohol analysis, the importance of multiple specimen analysis in alcohol-related death investigation is well understood. Quantitative alcohol determination in a variety of postmortem specimens may provide important interpretive information. In a total of 322 consecutive cases, blood and vitreous alcohol concentrations were compared. No alcohol was detected in either specimen in only 27 of the cases. In the remaining 295 investigations, alcohol was detected in the vitreous fluid, blood, or both. Analysis of the data and presentation of case studies reinforce the need for multiple specimen analysis in alcohol-related death investigation. Postmortem blood and vitreous alcohol concentrations were compared in a series of 295 alcohol-positive cases. The vitreous alcohol concentration (VAC) exceeded the blood alcohol concentration (BAC) in 209 cases (71%). blood alcohol concentrations exceeded vitreous concentrations in 81 cases (27%), and the concentrations were equivalent in 5 cases (2%). For the purpose of this study, samples that were negative in both specimens were excluded. In casework where the VAC > BAC, linear regression analysis indicated an R2 value of 0.958 (n = 209) and a VAC approximately 16% higher than the BAC. The VAC/BAC ratio was more variable at lower BACs (< 0.1 g/100 mL). The source of blood for this data set was predominantly femoral (n = 203), followed by heart (n = 5) and pleural cavity (n = 1). Although VAC/BAC ratios were more consistent at concentrations of 0.1 g/100 mL and above, the overall ratio ranged from 1.01 to 2.20. Of the 81 cases where BAC > VAC, a total of 24 cases indicated no vitreous alcohol. The range of blood alcohol concentrations among these cases was widely variable (0.01 to 0.30 g/100 mL). Unlike the VAC/BAC data set which consisted of 97% femoral blood, the source of blood in the BAC > VAC data set was slightly more variable. Of the 81 cases where BAC > VAC the blood source consisted of femoral (n = 68), heart (n = 8), pleural cavity (n = 2), carotid (n = 1), jugular (n = 1), and chest blood (n = 1). All analyses were conducted using dual-column gas chromatography with flame-ionization detection (GC-FID) with a reporting limit of 0.01 g/100 mL ethanol in postmortem samples. A series of case studies are used to demonstrate postmortem interpretive issues and the benefits associated with multiple specimen analysis. Cases include postmortem production of ethanol, rapid or unexpected death during the absorptive phase, and site-dependent differences following traumatic injury. Actual case studies involving other volatile organic compounds are also presented including isopropanol and acetone from endogenous and exogenous sources. Many of these cases studies highlight the difficulty associated with postmortem alcohol interpretation in the absence of multiple specimens or adequate case history.- - - - - - - - - - ranking = 2keywords = heart (Clic here for more details about this article) |
10/27. Mitral annuloplasty causing left circumflex injury and infarction: novel use of intravascular ultrasound to diagnose suture injury.Suture injury of the left circumflex coronary artery and infarction may be an under-recognized complication of mitral valve annuloplasty. Our cases illustrate a potential role for early coronary angiography in patients who have persistent hemodynamic instability or ventricular irritability, which may be related to left circumflex artery injury. This potentially devastating complication of mitral annuloplasty can be diagnosed by use of intravascular ultrasound to distinguish suture injury from an atherosclerotic lesion.- - - - - - - - - - ranking = 0.22149551905167keywords = valve (Clic here for more details about this article) |
