    This project`s aim was to characterize changes in microvascular endothelial cells (HMVEC) and type II alveolar epithelial cells (AEpC) after exposure to phosgene in vitro for evaluation of prophylaxis and therapy. We measured release of eicosanoids from lung HMVEC: 6-ket-PGF1a and thromboxane B2 both increase approx. 2 h after exposure to 900 ppm-min phosgene. Smaller but statistically significant increases in leukotrienes C4, D4, and E4 are also seen after 2 h. Over the same time course, phosgene-exposed HMVEC which were not killed by exposure accumulate intracytosolic calcium (measured with fluo-3), and generate reactive oxygen metabolites (detected with CDCFH). After a phosgene dose of 300 ppm-min, changes in HMVEC membranes result in loss of cytosolic esterase activity (detected with calcein-AM), along with increased binding of intercalating dyes to DNA. Additional signs of cell injury are decreased lysosomal uptake of acridine orange, and loss of mitochondrial membrane potential (measured by rhodamine 123 uptake and JC-1 aggregation). These changes all occur rapidly after exposure and remain stable for several hours. Type II AEpC are more resistant to phosgene: measures of cytotoxic injury are minimally altered by phosgene levels up to 900 ppm-min and mitochondrial membrane potential is maintained even at this dose. Intracellular calcium levels stay low even after addition of ionophores to A549 AEpC. Permeability of both type II AEpC and HMVEC monolayers increases after exposure to 900 ppm%min phosgene, measured by decreased electrical resistance and increased mannitol permeation. Pretreatment with approx. 10-2 M N-acetyl cysteine and approx. 10-4 M pyrrolidine dithiocarbamate protects against some cytotoxic changes, suggesting that intracellular reactive oxygen species may contribute to phosgene induced injury.

    Inhalation is the most important route of exposure for phosgene. A latency period occurs before phosgene affects the target organ, the lungs. The odor threshold is between 0.5 and 1.5 ppm, and the odor has been described as similar to newly-mown hay. Toxic effects have been reported at concentrations below the threshold. On initial exposure, phosgene can undergo hydrolysis and form hydrogen chloride which can be slightly irritating to the upper respiratory tract and eyes; the amount formed is limited by the low water solubility of phosgene. Once inhaled to the lower respiratory tract, phosgene undergoes an acylation reaction with amino, hydroxyl and sulfhydryl groups causing destruction of protein, lipids, and disruption of cellular functions. In response to this destruction, after a latency period of 1-24 hours, a breakdown in the blood-air barrier occurs and protein rich fluid accumulates in the lungs. Most commonly, death occurs within 48 hours after exposure from a progressive pulmonary edema and anoxia. At very high concentrations, death can occur from acute heart failure prior to the start of the pulmonary edema. Data on humans are limited to occupational exposures or accounts from the use of phosgene in World War I. Animal studies with phosgene show a steep dose-response curve for pulmonary edema and mortality. Animal studies also indicate little species variability as all species exposed developed similar clinical signs (dyspnea, pulmonary edema, labored breathing) and histopathological lesions in the lungs. While there are no chronic animal data, subchronic studies indicate little accumulation of phosgene or increased severity of lesions with continuous exposure.

    With the increasing tempo of military conflicts in the last decade, much has been learnt about imaging battlefield casualties in the acute setting. Ultrasound in the form of focused abdominal sonography in trauma (FAST) has proven invaluable in emergency triage of patients for immediate surgery. Multidetector CT allows accurate determination of battlefield trauma injuries. It permits the surgeons and anaesthetists to plan their interventions more thoroughly and to be made aware of clinically occult injuries. There are common injury patterns associated with blast injury, gunshot wounds and blunt trauma. While this body of knowledge is most applicable to the battlefield, there are parallels with peacetime radiology, particularly in terrorist attacks and industrial accidents. This pictorial review is based on the experiences of a UK radiologist deployed in Afghanistan in 2010. PMID:22806621

  6. Mortality and causes of death among workers exposed to phosgene in 1943-45

    Mortality and causes of death from death certificates were analyzed among workers exposed to phosgene while working at a uranium-processing plant in Tennessee in 1943-45. Standardized mortality ratios (SMRs) were calculated by using death rates for U.S. white males. As of 1979, SMRs for all causes and for various selected causes were similar in 694 male chemical workers chronically exposed to low levels of phosgene in 1943-45 and in 9280 male controls who worked at the same plant. SMRs for diseases of the respiratory system were 107 (14 observed vs. 13.07 expected) in the chemical workers and 119 (292 observed vs. 245.75 expected) in the controls. In a group of 106 males who were acutely exposed to high levels of phosgene, there were 41 deaths observed vs. 33.87 expected (SMR = 121; 95% confidence limits = 86 and 165). One death, occurring within 24 hours of exposure, was from pulmonary edema due to phosgene poisoning (coded to accidental causes). Five deaths were coded to diseases of the respiratory system (SMR = 266; 95% CL = 86 and 622); in 2 of these 5 deaths, bronchitis due to phosgene exposure had been reported in 1945. Among 91 female workers with acute high-level phosgene exposure, frequencies of symptoms and early health effects (pneumonitis and bronchitis) differed from those reported for the 106 male cases; preliminary data on vital status of these females are too incomplete for analysis, and further follow-up is needed.

    The PAL protocol was applied to estimate inhalation exposure limits for phosgene (CG). Data on humans are limited to occupational exposures or accounts from the use of phosgene as a chemical warfare agent in WWI. Animal studies with phosgene show a steep dose-response curve for pulmonary edema and mortality with little species variability in effects. Although immediately upon exposure lacrimation and upper respiratory irritation can occur, the main effect in the target organ, a progressive pulmonary edema, occurs after a latency period of 1-24 hours. PAL estimates were approved by the Expert Consultation Panel for Provisional Advisory Levels in May 2007. Exposure limits for oral exposure to CG are not developed due to insufficient data. PAL estimates for inhalation exposure to CG are presented: The 24-hour PAL values for severity levels 1, 2, and 3 are 0.0017, 0.0033 and 0.022 ppm, respectively. The 30-day PAL values are 0.0006 and 0.0012 ppm for the PAL 1 and 2 values, respectively. These 30-day inhalation values were also accepted as the 90-day and 2-year PAL 1 and 2 values. Data were not available for deriving 30-day, 90-day and 2-year PAL 3 values.

    The Provisional Advisory Level (PAL) protocol was applied to estimate inhalation exposure limits for phosgene (CG). Three levels (PAL 1, PAL 2, and PAL 3), distinguished by severity of toxic effects, are developed for 24-hour, 30-day, 90-day, and 2-year durations of potential drinking water and inhalation exposures for the general public. For background on the PAL program and a description of the methodology used in deriving PALs, the reader is referred to accompanying papers in this Supplement. Data on humans are limited to occupational exposures or accounts from the use of phosgene as a chemical warfare agent in World War I. Animal studies with phosgene show a steep dose-response curve for pulmonary edema and mortality, with little species variability in effects. Although immediately upon exposure lacrimation and upper respiratory irritation can occur, the main effect in the target organ, a progressive pulmonary edema, occurs after a latency period of 1-24 hours.

The 30- and 90-day PAL values are 0.0006 and 0.0012 ppm for the PAL 1 and 2 values, respectively. These inhalation values were also accepted as the 2-year PAL 1 and 2 values because severity of lesions in the key study did not increase when exposures were extended from 4 weeks to 12 weeks. Data were not available for deriving 30-day, 90-day, and 2-year PAL 3 values. PMID:19827940

    One of the many goals of the green chemistry movement is to eliminate the use of phosgene (COCl{sub 2}), an extremely hazardous compound used in many syntheses, including the production of carbamates, organic carbonates, and polymers. One of the most interesting options for eliminating this compound is to replace it with CO{sub 2}. In addition to carbon dioxide`s abundance and benign nature, it has the benefits of recycling carbon and of reducing the amount of CO{sub 2} released into the atmosphere when its use is linked with other processes that emit CO{sub 2}. Several synthetic strategies that do not use phosgene are under development. The authors briefly review the most interesting ones and then expand on the use of CO{sub 2} as a potential building block for organic carbamates, carbonates, and isocyanates. One of these routes, polycarbonate synthesis, is already in industrial-scale operation: PAC Polymers Inc. currently produces CO{sub 2}-epoxide copolymers. The synthesis of carbamates and substituted ureas has been developed, and this process awaits industrial exploitation.

    Modern tactical communications systems rely on radios to support network and user connectivity. One of the challenges for network planners and managers is to make best use of scarce and vulnerable frequency spectrum resources to support the communication needs of war fighters. With the wide variety of Iris radio types typically to be deployed in the battlefield (ranging from high frequency to super high frequency), a comprehensive suite of tools is necessary to ensure that frequency interference is kept minimum. Without a sophisticated frequency spectrum management system, the most advanced tactical communications systems could be rendered useless, jeopardizing human life and national security. For these reasons, it is important to develop an Iris wide battlefield spectrum management capability that takes full advantage of current frequency spectrum management research and development (R&D), related tools, and supporting technology for assigning frequencies. This session briefly describes various assignment strategies being adopted in the Iris BFSM for overcoming cosite/collocated/farsite interferences along with the propagation models [from high frequency (HF) to super high frequency (SHF)] used for the assignment of frequencies. Also a brief thread outlining the process for generating frequency allocation/assignment request and analysis of frequency interference is discussed.

    Small air and ground physical agents (robots) will be ubiquitous on the battlefield of the 21st century, principally to lower the exposure to harm of our ground forces in urban and open terrain scenarios. Teams of small collaborating physical agents conducting tasks such as Reconnaissance, Surveillance, and Target Acquisition (RSTA), intelligence, chemical and biological agent detection, logistics, decoy, sentry; and communications relay will have advanced sensors, communications, and mobility characteristics. It is anticipated that there will be many levels of individual and team collaboration between the soldier and robot, robot to robot, and robot to mother ship. This paper presents applications and infrastructure components that illustrate each of these levels. As an example, consider the application where a team of twenty small robots must rapidly explore and define a building complex. Local interactions and decisions require peer to peer collaboration. Global direction and information fusion warrant a central team control provided by a mother ship. The mother ship must effectively deliver/retrieve, service, and control these robots as well as fuse the information gathered by these highly mobile robot teams. Any level of collaboration requires robust communications, specifically a mobile ad hoc network. The application of fixed ground sensors and mobile robots is also included in this paper. This paper discusses on going research at the U.S. Army Research Laboratory that supports the development of multi-robot collaboration. This research includes battlefield visualization, intelligent software agents, adaptive communications, sensor and information fusion, and multi-modal human computer interaction.

  1. NOS-2 Inhibition in Phosgene-Induced Acute Lung Injury

    Phosgene exposure via an industrial or warfare release produces severe acute lung injury (ALI) with high mortality, characterized by massive pulmonary edema, disruption of epithelial tight junctions, surfactant dysfunction, and oxidative stress. There are no targeted treatments for phosgene-induced ALI. Previous studies demonstrated that nitric oxide synthase 2 (NOS-2) is upregulated in the lungs after phosgene exposure; however, the role of NOS-2 in the pathogenesis of phosgene-induced ALI remains unknown. We previously demonstrated that NOS-2 expression in lung epithelium exacerbates inhaled endotoxin-induced ALI in mice, mediated partially through downregulation of surfactant protein B (SP-B) expression. Therefore, we hypothesized that a selective NOS-2 inhibitor delivered to the lung epithelium by inhalation would mitigate phosgene-induced ALI. Inhaled phosgene produced increases in bronchoalveolar lavage fluid protein, histologic lung injury, and lung NOS-2 expression at 24 h. Administration of the selective NOS-2 inhibitor 1400 W via inhalation, but not via systemic delivery, significantly attenuated phosgene-induced ALI and preserved epithelial barrier integrity. Furthermore, aerosolized 1400 W augmented expression of SP-B and prevented downregulation of tight junction protein zonula occludens 1 (ZO-1), both critical for maintenance of normal lung physiology and barrier integrity. We also demonstrate for the first time that NOS-2-derived nitric oxide downregulates the ZO-1 expression at the transcriptional level in human lung epithelial cells, providing a novel target for ameliorating vascular leak in ALI. Our data demonstrate that lung NOS-2 plays a critical role in the development of phosgene-induced ALI and suggest that aerosolized NOS-2 inhibitors offer a novel therapeutic strategy for its treatment.

    Autonomous robots for the battlefield offer a tantalizing alternative to manned warfare. These systems rely upon many well established technological areas. Near term applications of autonomous battlefield robots (ABRs) are possible in such mission areas as surveillance and communications support. Such more advanced applications as weapons and countermeasures control await at least the development of fault tolerant information processing resources. Several open research issues still limit the current realizable performance of ARBs. In spite of these limitations, ABRs should be implemented for near term applications to gain the systems experience necessary to construct more capable ABR systems.

    To modernize the army for the 21st century, the U.S. Army Digitization Office (ADO) initiated in 1995 the Force XXI Battle Command Brigade-and-Below (FBCB2) Applique program which became a centerpiece in the U.S. Army's master plan to win future information wars. The Applique team led by TRW fielded a 'tactical Internet' for Brigade and below command to demonstrate the advantages of 'shared situation awareness' and battlefield digitization in advanced war-fighting experiments (AWE) to be conducted in March 1997 at the Army's National Training Center in California. Computing Devices is designated the primary hardware developer for the militarized version of the battlefield awareness computers. The first generation of militarized battlefield awareness computer, designated as the V3 computer, was an integration of off-the-shelf components developed to meet the agressive delivery requirements of the Task Force XXI AWE. The design efficiency and cost effectiveness of the computer hardware were secondary in importance to delivery deadlines imposed by the March 1997 AWE. However, declining defense budgets will impose cost constraints on the Force XXI production hardware that can only be met by rigorous value engineering to further improve design optimization for battlefield awareness without compromising the level of reliability the military has come to expect in modern military hardened vetronics. To answer the Army's needs for a more cost effective computing solution, Computing Devices developed a second generation 'combat ready' battlefield awareness computer, designated the V3+, which is designed specifically to meet the upcoming demands of Force XXI (FBCB2) and beyond. The primary design objective is to achieve a technologically superior design, value engineered to strike an optimal balance between reliability, life cycle cost, and procurement cost. Recognizing that the diverse digitization demands of Force XXI cannot be adequately met by any one computer hardware

    Toxic industrial chemicals are used throughout the world to produce everyday products such as household and commercial cleaners, disinfectants, pesticides, pharmaceuticals, plastics, paper, and fertilizers. These chemicals are produced, stored, and transported in large quantities, which poses a threat to the local civilian population in cases of accidental or intentional release. Several of these chemicals have no known medical countermeasures for their toxic effects. Phosgene is a highly toxic industrial chemical which was used as a chemical warfare agent in WWI. Exposure to phosgene causes latent, non-cardiogenic pulmonary edema which can result in respiratory failure and death. The mechanisms of phosgene-induced pulmonary injury are not fully identified, and currently there is no efficacious countermeasure. Here, we provide a proposed mechanism of phosgene-induced lung injury based on the literature and from studies conducted in our lab, as well as provide results from studies designed to evaluate survival efficacy of potential therapies following whole-body phosgene exposure in mice. Several therapies were able to significantly increase 24h survival following an LCt50-70 exposure to phosgene; however, no treatment was able to fully protect against phosgene-induced mortality. These studies provide evidence that mortality following phosgene toxicity can be mitigated by neuro- and calcium-regulators, antioxidants, phosphodiesterase and endothelin receptor antagonists, angiotensin converting enzymes, and transient receptor potential cation channel inhibitors. However, because the mechanism of phosgene toxicity is multifaceted, we conclude that a single therapeutic is unlikely to be sufficient to ameliorate the multitude of direct and secondary toxic effects caused by phosgene inhalation.

  14. Review of clinical experience in handling phosgene exposure cases.

    Regan, R A

    1985-10-01

    In summary, we have described our method of treating phosgene inhalation injury. We have presented two serious cases in detail which demonstrate that survival was associated with aggressive therapy. Several points should be mentioned. The pulmonary edema and resulting fluid and foam production can be so copious as to overwhelm efforts to place an endotracheal tube. The solution is early intubation by the nearest experienced person at the first hint of edema or pulmonary failure. Adequate support of the patient's blood volume is imperative to avert hypovolemic shock and renal failure. A balloon flotation catheter is desirable to monitor pulmonary wedge pressure and avoid overload. Follow-up pulmonary function studies and chest x-rays are recommended 2-3 months after hospital discharge. We have not yet found a reliable test to determine which cases will progress to pulmonary edema. The LDH appears to be the only consistently elevated sign in more serious cases. Finally, we would like to make a plea for the sharing of information from instances of fatal phosgene injury so that the facts can be studied and applied to future cases. PMID:3916030

  19. Atmospheric chemistry of toxic contaminants 4. Saturated halogenated aliphatics: Methyl bromide, epichlorhydrin, phosgene

    SciTech Connect

    Grosjean, D. )

    1991-01-01

    Mechanisms are outlined for the reactions that contribute to in-situ formation and atmospheric removal of the saturated halogenated aliphatic contaminants methyl bromide, epichlorhydrin, and phosgene. In-situ formation is important only for phosgene and involves the reaction of OH with chloroethenes and other chlorinated hydrocarbons. A ranking of these phosgene precursors is given using data for precursor ambient concentrations and chemical reactivity. The three toxic compounds studied are long-lived in the atmosphere, where removal of phosgene and methyl bromide by chemical reactions is negligibly slow. Epichlorhydrin is removed slowly by reaction with OH, leading to formaldehyde, chloroacetaldehyde, and the chlorinated peroxyacyl nitrate CH{sub 2}ClC(O)OONO{sub 2}.

    1986-01-01

    A comparison of the concentration-response effects of inhaled ozone (O/sub 3/) and phosgene (COCl/sub 2/) in different species of laboratory animals was made in order to better understand the influence of the choice of species in inhalation toxicity studies. The effect of 4-h exposures to ozone at concentrations of 0.2, 0.5, 1.0, and 2.0 ppm, and to COCl/sub 2/ and 0.1, 0.2, 0.5, and 1.0 ppm was determined in rabbits, guinea pigs, rats, hamsters, and mice. Lavage fluid protein (LFP) accumulation 18-20 h after exposure was used as the indicator of O3- and COCl/sub 2/-induced pulmonary edema. All species had similar basal levels of LFP (250-350 mg/ml) when a volume of saline that approximated the total lung capacity was used to lavage the collapsed lungs. Ozone effects were most marked in guinea pigs, which showed significant effects at 0.2 ppm and above. Mice, hamsters, and rats showed effects at 1.0 ppm O3 and above, while rabbits responded only at 2.0 ppm O3. Phosgene similarly affected mice, hamsters, and rats at 0.2 ppm and above, while guinea pigs and rabbits were affected at 0.5 ppm and above. Percent recovery of lavage fluid varied significantly between species, guinea pigs having lower recovery than other species with both gases. Lavage fluid recovery was lower following exposure to higher levels of O3 but not COCl/sub 2/. Results of this study indicate that significant species differences are seen in the response to low levels of O3 and COCl/sub 2/. These differences do not appear to be related in a simple manner to body weight.

  1. Characterization of a nose-only inhaled phosgene acute lung injury mouse model

    Context Phosgene’s primary mode of action is as a pulmonary irritant characterized by its early latent phase where life-threatening, non-cardiogenic pulmonary edema is typically observed 6–24 h post-exposure. Objective To develop an inhaled phosgene acute lung injury (ALI) model in C57BL/6 mice that can be used to screen potential medical countermeasures. Methods A Cannon style nose-only inhalation exposure tower was used to expose mice to phosgene (8 ppm) or air (sham). An inhalation lethality study was conducted to determine the 8 ppm median lethal exposure (LCt50) at 24 and 48 h post-exposure. The model was then developed at 1.2 times the 24 h LCt50. At predetermined serial sacrifice time points, survivors were euthanized, body and lung weights collected, and lung tissues processed for histopathology. Additionally, post-exposure clinical observations were used to assess quality of life. Results and discussion The 24-hour LCt50 was 226ppm*min (8 ppm for 28.2 min) and the 48-hour LCt50 was 215ppm*min (8 ppm for 26.9 min). The phosgene exposed animals had a distinct progression of clinical signs, histopathological changes and increased lung/body weight ratios. Early indicators of a 1.2 times the 24-hour LCt50 phosgene exposure were significant changes in the lung-to-body weight ratios by 4 h post-exposure. The progression of clinical signs and histopathological changes were important endpoints for characterizing phosgene-induced ALI for future countermeasure studies. Conclusion An 8 ppm phosgene exposure for 34 min (1.2 × LCt50) is the minimum challenge recommended for evaluating therapeutic interventions. The predicted higher mortality in the phosgene-only controls will help demonstrate efficacy of candidate treatments and increase the probability that a change in survival rate is statistically significant PMID:26671199

  3. Robotics and the battlefield of the future

    NASA Astrophysics Data System (ADS)

    Solem, Erik

    The possible future roles for robotics are discussed from a military and strategic point of view. The future battlefield itself is then examined along with some of the anticipated changes which may take place. Robotics is likely to play a major role in future military operations. Robotic equipment will be increasingly used on the battlefield, aboard ships, on land, in the air, and in space applications. Potential application areas extend beyond such important operations as minefield clearing, reconnaissance, ammunition handling, and construction tasks. The future battlefield itself will change with the introduction of new forms and factors of combat. There will be qualitatively different forms of conflict in which robotics may play specific and important roles, such as masked clashes, anti-terrorist activities, and anti-industrial sabotage operations. The battlefield itself will widen and include new strategic factors of increasing importance. Our understanding and use of robotics will also change. Nonconventional strategies are needed as are new and different conflict scenarios, some of which are examined.

  20. Automated military unit identification in battlefield simulation

    SciTech Connect

    Stroud, P.; Gordon, R.

    1997-05-01

    It is the nature of complex systems, composed of many interacting elements, that unanticipated phenomena develop. Computer simulation, in which the elements of a complex system are implemented as interacting software objects (actors), is an effective tool to study collective and emergent phenomena in complex systems. A new cognitive architecture is described for constructing simulation actors that can, like the intelligent elements they represent adapt to unanticipated conditions. This cognitive architecture generates trial behaviors, estimates their fitness using an internal representation of the system, and has an internal apparatus for evolving a population of trial behaviors to changing environmental conditions. A specific simulation actor is developed to evaluate surveillance radar images of moving vehicles on battlefields. The vehicle cluster location, characterization and discrimination processes currently performed by intelligent human operators were implemented into a parameterized formation recognition process by using a newly developed family of 2D cluster filters. The mechanics of these cluster filters are described. Preliminary results are presented in which this GSM actor demonstrates the ability not only to recognize military formations under prescribed conditions, but to adapt its behavior to unanticipated conditions that develop in the complex simulated battlefield system.

  1. River as a part of ground battlefield

    NASA Astrophysics Data System (ADS)

    Vračar, Miodrag S.; Pokrajac, Ivan; Okiljević, Predrag

    2013-05-01

    The rivers are in some circumstances part of the ground battlefield. Microseisms induced at the riverbed or ground at the river surrounding might be consequence of military activities (military ground transports, explosions, troop's activities, etc). Vibrations of those fluid-solid structures are modeled in terms of solid displacement and change of fluid pressure. This time varying fluid pressure in river, which originates from ground microseisms, is possible to detect with hydrophones. Therefore, hydroacoustic measurements in rivers enables detecting, identification and localization various types of military noisy activities at the ground as and those, which origin is in the river water (hydrodynamics of water flow, wind, waves, river vessels, etc). In this paper are presented river ambient noise measurements of the three great rivers: the Danube, the Sava and the Tisa, which flows in north part of Serbia in purpose to establish limits in detection of the ground vibrations in relatively wide frequency range from zero to 20 kHz. To confirm statement that the river is a part of ground battlefield, and that hydroacoustic noise is possible to use in detecting and analyzing ground microseisms induced by civil or military activities, some previous collected data of hydroacoustic noise measurement in the rivers are used. The data of the river ambient noise include noise induced by civil engineering activities, that ordinary take place in large cities, noise that produced ships and ambient noise of the river when human activities are significantly reduced. The poly spectral method was used in analysis such events.

    Getting to wounded soldiers on the battlefield is a precarious task, and medics have a very high casualty rate. It is therefore a vital importance to prioritize which soldiers to attend to first. The first step is to detect life signs - if a soldier is dead or alive, and prioritize recovery of live soldiers. The second step is to obtain vital signs from live soldiers, and use this to prioritize which are in most urgent need of attention. Our team at Kai Sensors, University of Hawaii and University of Florida is developing Doppler radar heart sensing technology that provides the means to detect life signs, respiration and/or heart beat, at a distance, even for subjects lying motionless, e.g., unconscious subjects, wearing body armor, and hidden from direct view. Since this technology can deliver heart rate information with high accuracy, it may also enable the assessment of a subject's physiological and psychological state based on heart rate variability (HRV) analysis. Thus, the degree of a subject's injury may also be determined. The software and hardware developments and challenges for life signs detection and monitoring for battlefield triage will be discussed, including heart signal detection from all four sides of the human body, detection in the presence of body armor, and the feasibility of HRV parameter extraction.

    The ability to analyze highly toxic chemical warfare agents (CWAs) and related chemicals in a rapid and precise manner is essential in order to alleviate serious threats to humankind and public security caused by unexpected terrorist attacks and industrial accidents. In this investigation, we designed a o-phenylenediamine-pyronin linked dye that is capable of both fluorogenic and colorimetric discrimination between phosgene and the prototypical nerve-agent mimic, diethyl chlorophosphate (DCP) in the solution or gas phase. Moreover, this dye has been used to construct a portable kit that can be employed for real-time monitoring of DCP and phosgene in the field, both in a discriminatory manner, and in a simple and safe way.

    In this study, the authors demonstrated the acute pulmonary cellular changes associated with phosgene exposure, by both light (L.M.) and electron microscopy (E.M.). Adult, unanesthetized sheep were exposed for 10 minutes to either 767 ppm/min of phosgene or room air. Four hours post exposure, all animals were killed, wet lung weight was obtained, and lung tissue was collected for L.M. and E.M. In sheep exposed to phosgene, wet lung weight was significantly higher. Grossly, the lung was congested and edematous. Alveolar and interstitial edema, fibrin and neutrophil exudation in the air spaces, and increased alveolar macrophages, were prominent by L.M. E.M. of Type I pneumocytes showed intracellular swelling, necrosis, and denuding of basement membrane with preservation of the tight junctions. Type II pneumocytes showed loss of lamellar bodies, cytoplasmic swelling, and damage to the endoplasmic reticulum. Endothelial cells showed increased density and vesicular activity, cytoplasmic swelling, and displacement of basement membrane. This study supports the biochemical data the authors previously reported.

    1996-06-01

    To meet its objectives of winning the information ware and digitizing the battlefield, the U.S. Army must leverage advances in commercial technology. The Department of Defense has adopted a new approach to acquiring and fielding systems in response to economic realities and the need to incorporate rapidly advancing commercial technology into Army systems. This approach calls for the evaluation of commercial breakthroughs in a laboratory environment followed by evaluation by the user in a warfighting experiment. The most promising products are then transitioned to a program executive officer/project manager for accelerated acquisition and fielding. The U.S. Army Communications-Electronics Command (CECOM) Research, Development and Engineering Center Space & Terrestrial Communications Directorate is working with the Advanced Research Projects Agency (ARPA) to study the applicability of personal communications systems and related technologies for Army applications. The results of this cooperative effort were demonstrated in 1995 through the use of the trunked Land Mobile Radio (LMR) during field exercises. This paper will describe the joint CECOM/ARPA programs that sponsor the evaluation of commercial technologies, characteristics of the LMR and the details of its interface with the legacy systems, and current plans for further experimentation/evaluation.

    Three o-phenylendiamine (OPD) derivatives, containing 4-chloro-7-nitrobenzo[c][1,2,5]oxadiazole (NBD-OPD), rhodamine (RB-OPD), and 1,8-naphthalimide (NAP-OPD) moieties, were prepared and tested as phosgene chemosensors. Unlike previously described methods to sense this toxic agent, which rely on chemical processes that transform alcohols and amines to respective phosphate esters and phosphoramides, the new sensors operate through a benzimidazolone-forming reaction between their OPD groups and phosgene. These processes promote either naked eye visible color changes and/or fluorescence intensity enhancements in conjunction with detection limits that range from 0.7 to 2.8 ppb. NBD-OPD and RB-OPD-embedded polymer fibers, prepared using the electrospinning technique, display distinct color and fluorescence changes upon exposure to phosgene even in the solid state.

    Hydrogen cyanide, cyanogen chloride and phosgene are produced in tremendously large quantities today by the chemical industry. The compounds are also particularly attractive to foreign states and terrorists seeking an inexpensive mass-destruction capability. Along with contemporary warfare agents, therefore, the US Army evaluates protective equipment used by warfighters and domestic emergency responders against the compounds, and requires their certification at > or = 95 carbon atom % before use. We have investigated the (13)C spin-lattice relaxation behavior of the compounds to develop a quantitative NMR method for characterizing chemical lots supplied to the Army. Behavior was assessed at 75 and 126 MHz for temperatures between 5 and 15 degrees C to hold the compounds in their liquid states, dramatically improving detection sensitivity. T(1) values for cyanogen chloride and phosgene were somewhat comparable, ranging between 20 and 31 s. Hydrogen cyanide values were significantly shorter at 10-18 s, most likely because of a (1)H--(13)C dipolar contribution to relaxation not possible for the other compounds. The T(1) measurements were used to derive relaxation delays for collecting the quantitative (13)C data sets. At 126 MHz, only a single data acquisition with a cryogenic probehead gave a signal-to-noise ratio exceeding that necessary for certifying the compounds at > or = 95 carbon atom % and 99% confidence. Data acquired at 75 MHz with a conventional probehead, however, required > or = 5 acquisitions to reach this certifying signal-to-noise ratio for phosgene, and >/= 12 acquisitions were required for the other compounds under these same conditions. In terms of accuracy and execution time, the NMR method rivals typical chromatographic methods. PMID:17924355

    Like the wars predating the First World War where human foot soldiers were deemed tools in the battlefield against an enemy, so too are the host immune cells of a patient battling a malignant gastric cancer. Indeed, the tumour microenvironment resembles a battlefield, where the patient's immune cells are the defence against invading tumour cells. However, the relationship between different immune components of the host response to cancer is more complex than an "us against them" model. Components of the immune system inadvertently work against the interests of the host and become pro-tumourigenic while other components soldier on against the common enemy - the tumour cell.

    2011-01-01

    Army transformation to a brigade-centric force has created a distributed battlefield, challenging the surveillance and logistical supply of field water. The daily requirement of up to 15 gal of potable water per person per day from bulk water supplies has been achievable for many years using currently fielded ROWPUs. However, the need to reduce the transport of water and move towards a sustainable force has created a gap in materiel capable of producing safe water at the individual and unit level. While materiel development is slow, the PM community, tasked with doctrine development and battlefield oversight of field water, is beginning to address the requirements of field water on the changed battlefield. In addition to materiel gaps, the transformed battlefield has created a lack of trained personnel for water production and oversight. Without trained operators and PM oversight, to what level of health risk are consumers of this water exposing themselves? Currently PM is unable to answer this question but is working diligently with the RDT&E community to develop materiel solutions, and with the medical community to provide interim guidance to reduce the potential health risks to using such equipment.

    Acute poisoning with pesticides is a global public health problem and accounts for as many as 300,000 deaths worldwide every year. The majority of deaths occur due to exposure to organophosphates, organochlorines and aluminium phosphide. Organophosphate compounds inhibit acetylcholinesterase resulting in acute toxicity. Intermediate syndrome can develop in a number of patients and may lead to respiratory paralysis and death. Management consists of proper oxygenation, atropine in escalating doses and pralidoxime in high doses. It is Important to decontaminate the skin while taking precautions to avoid secondary contamination of health personnel. Organochlorine pesticides are toxic to the central nervous system and sensitize the myocardium to catecholamines. Treatment involves supportive care and avoiding exogenous sympathomimetic agents. Ingestion of paraquat causes severe inflammation of the throat, corrosive injury to the gastrointestinal tract, renal tubular necrosis, hepatic necrosis and pulmonary fibrosis. Administration of oxygen should be avoided as it produces more fibrosis. Use of immunosuppressive agents have improved outcome in patients with paraquat poisoning. Rodenticides include thallium, superwarfarins, barium carbonate and phosphides (aluminium and zinc phosphide). Alopecia is an atypical feature of thallium toxicity. Most exposures to superwarfarins are harmless but prolonged bleeding may occur. Barium carbonate Ingestion can cause severe hypokalaemia and respiratory muscle paralysis. Aluminium phosphide is a highly toxic agent with mortality ranging from 37% to 100%. It inhibits mitochondrial cytochrome c oxidase and leads to pulmonary and cardiac toxicity. Treatment is supportive with some studies suggesting a beneficial effect of magnesium sulphate. Pyrethroids and insect repellants (e.g. diethyltoluamide) are relatively harmless but can cause toxic effects to pulmonary and central nervous systems. Ethylene dibromide-a highly toxic, fumigant

    2008-04-01

    We present the framework for a battlefield change detection system that allows military analysts to coordinate and utilize live collection of airborne LIDAR range data in a highly interactive visual interface. The system consists of three major components: The adaptive and self-maintaining model of the battlefield selectively incorporates the minority of new data it deems significant, while discarding the redundant majority. The interactive interface presents the analyst with only the minute portion of the data the system deems relevant, provides tools to facilitate the decision making process, and adjusts its behavior to reflect the analyst's objectives. Finally, the cycle is completed by the generation of a goal map for the LIDAR collection hardware that instructs as to which areas should be sampled next in order to best advance the change detection task. All together, the system empowers analysts with the ability to make sense of a deluge of measurements by extracting the salient features and continually refining its definitions of relevancy.

    Uncontrolled hemorrhage has been considered as one of the most important factors for causing death on the battlefront. If given timely and efficient hemostatic medicines in pre-hospital setting, patients will obtain more time and chance to wait for medical treatment so as to save their lives. However, there is not a certain answer about which kind of hemostatic drugs can achieve efficacious effect to hemostasis in the battle. This review aims to summarize effective hemostatic medicines applied in battlefield from 41 articles. After analyzing and comparing the efficacy and complications of those products, we conclude that Fibrin Sealant Dressing, Celox and Woundstat are prior to other materials to stanch life-threatening extremity hemorrhage on the battlefield based on present research in the related area. Therefore, in the prevalence of some inevitable battlefield throughout the world, especially in the Middle Eastern countries, our findings suggest for the first time that the effective hemostatic device is not only a key point to link pre-hospital and hospital care but also an essential way to increase the survival rate of battlefront in the foreseeable future.

  10. Mapping a battlefield simulation onto message-passing parallel architectures

    NASA Technical Reports Server (NTRS)

    Nicol, David M.

    1987-01-01

    Perhaps the most critical problem in distributed simulation is that of mapping: without an effective mapping of workload to processors the speedup potential of parallel processing cannot be realized. Mapping a simulation onto a message-passing architecture is especially difficult when the computational workload dynamically changes as a function of time and space; this is exactly the situation faced by battlefield simulations. This paper studies an approach where the simulated battlefield domain is first partitioned into many regions of equal size; typically there are more regions than processors. The regions are then assigned to processors; a processor is responsible for performing all simulation activity associated with the regions. The assignment algorithm is quite simple and attempts to balance load by exploiting locality of workload intensity. The performance of this technique is studied on a simple battlefield simulation implemented on the Flex/32 multiprocessor. Measurements show that the proposed method achieves reasonable processor efficiencies. Furthermore, the method shows promise for use in dynamic remapping of the simulation.

  11. Helmet-mounted displays on the modern battlefield

    Casey, Curtis J.

    1999-07-01

    The increasing need for information being demanded by the battlefield commander in order to increase and maintain overall situational awareness in execution of the battle plan has caused a proliferation of devices and methods to be evaluated in Army Warfighting Experiments (AWEs). The results are often technology driving requirements without sufficient consideration given to the requirements of the soldier in battle. We are witnessing an overload of information being imposed on both the commander and the individual soldier, employing equipment capable of providing information from numerous sources across multiple, non-compatible platforms. Displays for this information range from large, power-hungry, big screen TVs to small, rugged computers and head-mounted displays (HMDs) for the individual combat soldier. The former requires large power supplies and is not suitable for a mobile army; the latter offers poor resolution and interferes with the duties of a soldier in combat. While we must continue to explore technology to solve some of the problems on the modern battlefield, we, as developers of technology, cannot lose sight of the purpose of the combat soldier: To wage war on a highly complex and mobile battlefield, whether it be in a country or urban environment; to seek out the enemy, engage him, destroy his ability to fight.

  12. [¹¹C]Phosgene: a versatile reagent for radioactive carbonyl insertion into medicinal radiotracers for positron emission tomography.

    2010-01-01

    [¹¹C]Phosgene has been playing a relatively modest but continuous and manifest role all along the history of radiochemistry for Positron Emission Tomography. It acts as a radiolabelling agent through carbonyl insertion, usually between heteroatoms, and benefits from a high chemical reactivity allowing for short reaction times. The aim of this review is to give an overview of this radiochemistry from its beginning until the present day. After drawing up the inventory of the various ways of its production, the reactions in which it has been employed and the labelled products that have been synthesised with it are catalogued. This comprises the reactions of [¹¹C]phosgene with primary, secondary and tertiary amines to labelled isocyanates and carbamoyl chlorides, which serve as intermediates for symmetrical and unsymmetrical [¹¹C]ureas and [¹¹C]carbamates, reactions with alcohols leading to labelled carbamates and carbonates via [¹¹C]chloroformates, cyclisation reactions to heterocycles and the radiochemistry of the secondary radiolabelling agents [¹¹C]urea and diethyl- or dimethyl [¹¹C]carbonate. Apart from this already vast field of chemical possibilities there should be room for extension of the use of [¹¹C]phosgene to other chemistry, notably that of C-¹¹C bond formation. PMID:20583989

    2014-12-01

    This study compares changes in cardiopulmonary function, selected endpoints in exhaled breath, blood, and bronchoalveolar lavage fluid (BAL) following a single, high-level 30-min nose-only exposure of rats to chlorine and phosgene gas. The time-course of lung injury was systematically examined up to 1-day post-exposure with the objective to identify early diagnostic biomarkers suitable to guide countermeasures to accidental exposures. Chlorine, due to its water solubility, penetrates the lung concentration-dependently whereas the poorly water-soluble phosgene reaches the alveolar region without any appreciable extent of airway injury. Cardiopulmonary endpoints were continually recorded by telemetry and barometric plethysmography for 20h. At several time points blood was collected to evaluate evidence of hemoconcentration, changes in hemostasis, and osteopontin. One day post-exposure, protein, osteopontin, and cytodifferentials were determined in BAL. Nitric oxide (eNO) and eCO2 were non-invasively examined in exhaled breath 5 and 24h post-exposure. Chlorine-exposed rats elaborated a reflexively-induced decreased respiratory rate and bradycardia whereas phosgene-exposed rats developed minimal changes in lung function but a similar magnitude of bradycardia. Despite similar initial changes in cardiac function, the phosgene-exposed rats showed different time-course changes of hemoconcentration and lung weights as compared to chlorine-exposed rats. eNO/eCO2 ratios were most affected in chlorine-exposed rats in the absence of any marked time-related changes. This outcome appears to demonstrate that nociceptive reflexes with changes in cardiopulmonary function resemble typical patterns of mixed airway-alveolar irritation in chlorine-exposed rats and alveolar irritation in phosgene-exposed rats. The degree and time-course of pulmonary injury was reflected best by eNO/eCO2 ratios, hemoconcentration, and protein in BAL. Increased fibrin in blood occurred only in chlorine

    Poisoning accounts for 40-60% of suicides, is the commonest medical emergency in small children, and an important source of occupational injury. Prevention of unintentional poisoning involves primarily education of parents. In intervention, the patient—not the poison—must be treated. Self-poisoners require supportive but firm handling. Treatment is directed towards prevention of further absorption, removal of absorbed poison, symptomatic or supportive therapy, and administration of systemic antidotes. Careful attention should be paid to the physician's legal responsibilities in cases of poisoning. Imagesp2032-a PMID:21286544

    , tremors, hypothermia, and bradycardia. Higher dosages may additionally cause nystagmus, agitation, tachypnea, tachycardia, ataxia, hyperexcitability, and seizures. Treatment of marijuana ingestion in animals is largely supportive. Vital signs including temperature and heart rate and rhythm must be continually monitored. Stomach content and urine can be tested for cannabinoids. Gas chromatography and mass spectrometry can be utilized for THC detection but usually may take several days and are not practical for initiation of therapy. Human urine drug-screening tests can be unreliable for confirmation of marijuana toxicosis in dogs owing to the interference of a large number of the metabolites in canine urine. False negatives may also arise if testing occurs too recently following THC ingestion. Thus, the use of human urine drug-screening tests in dogs remains controversial. No specific antidote presently exists for THC poisoning. Sedation with benzodiazepines may be necessary if dogs are severely agitated. Intravenous fluids may be employed to counter prolonged vomiting and to help control body temperature. Recently, the use of intralipid therapy to bind the highly lipophilic THC has been utilized to help reduce clinical signs. The majority of dogs experiencing intoxication after marijuana ingestion recover completely without sequellae. Differential diagnoses of canine THC toxicosis include human pharmaceuticals with central nervous system stimulatory effects, drugs with central nervous system depressant effects, macrolide parasiticides, xylitol, and hallucinogenic mushrooms.

    Bradberry, Sally M; Proudfoot, Alex T; Vale, J Allister

    2004-01-01

    Glyphosate is used extensively as a non-selective herbicide by both professional applicators and consumers and its use is likely to increase further as it is one of the first herbicides against which crops have been genetically modified to increase their tolerance. Commercial glyphosate-based formulations most commonly range from concentrates containing 41% or more glyphosate to 1% glyphosate formulations marketed for domestic use. They generally consist of an aqueous mixture of the isopropylamine (IPA) salt of glyphosate, a surfactant, and various minor components including anti-foaming and colour agents, biocides and inorganic ions to produce pH adjustment. The mechanisms of toxicity of glyphosate formulations are complicated. Not only is glyphosate used as five different salts but commercial formulations of it contain surfactants, which vary in nature and concentration. As a result, human poisoning with this herbicide is not with the active ingredient alone but with complex and variable mixtures. Therefore, It is difficult to separate the toxicity of glyphosate from that of the formulation as a whole or to determine the contribution of surfactants to overall toxicity. Experimental studies suggest that the toxicity of the surfactant, polyoxyethyleneamine (POEA), is greater than the toxicity of glyphosate alone and commercial formulations alone. There is insufficient evidence to conclude that glyphosate preparations containing POEA are more toxic than those containing alternative surfactants. Although surfactants probably contribute to the acute toxicity of glyphosate formulations, the weight of evidence is against surfactants potentiating the toxicity of glyphosate. Accidental ingestion of glyphosate formulations is generally associated with only mild, transient, gastrointestinal features. Most reported cases have followed the deliberate ingestion of the concentrated formulation of Roundup (The use of trade names is for product identification purposes only and

    The invention of the Microflown sensor has made it possible to measure acoustic particle velocity directly. An acoustic vector sensor (AVS) measures the particle velocity in three directions (the source direction) and the pressure. The sensor is a uniquely versatile battlefield sensor because its size is a few millimeters and it is sensitive to sound from 10Hz to 10kHz. This article shows field tests results of acoustic vector sensors, measuring rifles, heavy artillery, fixed wing aircraft and helicopters. Experimental data shows that the sensor is suitable as a ground sensor, mounted on a vehicle and on a UAV.

    Phosgene gas is a lower respiratory tract irritant. As such, it stimulates nociceptive vagal C-fiber-related reflexes in a dose-rate and concentration × exposure duration (C × t)-dependent manner. In rats, this reflex is characterized by extended apnea time periods, bradycardia, and hypothermia. Although inhalation exposures at nonlethal C × t products show rapid reversibility of reflexively induced changes in respiratory patterns, lethal C × t products seem to cause prolonged stimulation after discontinued exposure to phosgene. This observation has been taken as indirect evidence that phosgene-induced lethal lung edema is likely to be associated with a dysfunctional neurogenic control of cardiopulmonary and microvascular physiology. In order to verify this hypothesis, data from respiratory function measurements during and after the inhalation exposure to phosgene gas were compared with time-course measurements of cardiac function over 20 h post-phosgene exposure. These data were complemented by time-course analyses of nitric oxide (NO(e)) and carbon dioxide in exhaled breath, including time-dependent changes of extravasated protein in bronchoalveolar lavage fluid and hemoglobin in blood. The nitric oxidase synthetase inhibitors L-NAME and L-NIL were used to further elucidate the role of NO(e) in this type of acute lung injury and whether its analysis can serve as an early biomarker of pulmonary injury. Collectively, the sequence and time course of pathological events in phosgene-induced lung edema appear to suggest that overstimulated, continued sensorimotor vagal reflexes affect cardiopulmonary hemodynamics. A continued parasympathetic tone appears to be involved in this etiopathology. PMID:23143928

    Evolving threats encountered by coalition forces in Operation Iraqi Freedom drive the need for innovations in airborne intelligence, surveillance, and reconnaissance capabilities. In many cases, disruptive capabilities are created by linking existing technologies and new radical technologies in a novel way. Some of the radical technologies used in achieving these disruptive capabilities are existing prototypes or one-of-a-kind systems that are thrust into the field to quickly react to emerging threats. Horned Owl is one such rapidly developed innovative technical solution designed to meet immediate battlefield needs. This paper focuses on two key areas of this initiative. The first is the innovation champion establishing a collaborative environment which fosters creativity and allows the project to mature the disruptive capability. The second is the practical implication, or challenges of deploying experimental systems in a battlefield environment. Discussions of these two areas provide valuable lessons to guide future innovation champions when presented with the dual task of balancing system maturation with meeting operational demand.

    The use of a tourniquet to control bleeding is a necessity in both surgical and prehospital settings. Tourniquet application, if performed properly, can be a lifesaving procedure, particularly in a traumatic setting such as the battlefield. A tourniquet is easily applied and requires the use of a relatively uncomplicated piece of equipment. However, improper or prolonged placement of a tourniquet because of poor medical training can lead to serious injuries, such as nerve paralysis and limb ischemia. Here we present five case reports of improper tourniquet applications on the battlefield that resulted in nerve damage. We conclude that there is a need for improved training among medical personnel in the use of tourniquets, as well as a need for an adjustable-pressure, commercial-type sphygmomanometer cuff with a large surface area that is appropriate for application to all limbs parts. We also recommend that, in cases requiring the use of a tourniquet, the caregiver remove the tourniquet every 2 hours and assess the bleeding; if the bleeding has stopped, then the tourniquet should be replaced with a pressure bandage to minimize tissue damage.

    To perform multi-sensors simulations, the French DGA/DET (Directorate for Technical Evaluation of the French Ministry of Defense) uses CHORALE (simulated Optronic Acoustic Radar battlefield). CHORALE enables the user to create virtual and realistic multi spectral 3D scenes, and generates the physical signal received by one or several sensors, typically an IR sensor or an acoustic sensor. This article presents how the expertise is made to evaluate smart ammunition to detect ground target with infrared sensor and shape detector in a virtual battlefield with the environment CHORALE and the workshop AMOCO. The scene includes background with trees, houses, roads, fields, targets, and the ammunition. Each tool is explained to understand the physics phenomena in the scene to take into account atmospheric transmission, radiative parameters of objects and counter-measure devices. Then numeric models are described as the 6 DOF ballistics models, sensor model according precise positions inside the ammunition as well as the different steps of calculation between industrial model and technical model to obtain the global simulation. Finally, this paper explains some results of the evaluation compared with the true behavior after tests on proving ground. Then future evolutions are presented to perform similar evaluation with other kind of intelligent ammunition in a real-time model.

    Fish plays a significant role in human life, mainly as part of a balanced healthy diet and a good source of many of nutrients. However, contact with fish may be harmful or even life-threatening to man. Toxic effects, that fish exerts toward men (ichthyotoxism), result from envenomations by poison. ous fish equipped in venom apparatus (ichthyoacanthotoxism), direct contact with venom produced by skin glandules (ichthyocrinotoxism), or consuming fish containing toxins for nutritional purposes (ichthyosarcotoxism). In the present review, different fish-borne food poisonings are presented including their etiology, pathogenesis, symptomatology and treatment. In fact, the majority of fish poisonings are intoxications with toxins primary produced by bacteria, cyanobacteria and algae. These are consumed and accumulated in the food chain by herbivorous and predatory fish, that in turn may be a cause of poisonings in humans. PMID:23243919

    Although aspirin (acetylsalicylic acid) has become widely available without prescription, cases of self-poisoning due to overdose of salicylates are quite uncommon, with a low reported mortality. However, severe poisoning with these preparations is life threatening. Besides the aspirin, there are other sources of salicylate poisoning, such as an excessive application of topical agents, ingestion of salicylate containing ointments, use of keratolytic agents or agents containing methyl salicylate (e.g. oil of wintergreen). Most of these preparations are liquid, highly concentrated and lipid soluble, and, therefore, they are able to provoke a severe, rapid salicylate poisoning. On the basis of clinical and metabolic features or salicylate concentration in plasma it is very important to diagnose severe poisoning with salicylates in time and prescribe an adequate treatment. In the present review article various aspects of salicylate poisoning and its treatment are discussed: epidemiology, pharmacokinetics and pharmacodynamics of salicylates, clinical manifestations of their toxicity, management, enhanced elimination and prognosis.

    The effect of depleting lung ascorbic acid (AH{sub 2}) and nonprotein sulfhydryls (NPSH) on the acute inhalation toxicity of nitrogen dioxide (NO{sub 2}), ozone (O{sub 3}), and phosgene (COCl{sub 2}) was investigated in guinea pigs. The increase in bronchoalveolar lavage (BAL) fluid protein (an indicator of alveolar-capillary damage leading to increased permeability) was measured 16 to 18 hr following a 4 hr exposure to the gas in animals deficient in (AH{sub 2}) or NPSH. Gas concentrations were chosen which produced low but significant increases in BAL protein. Lung (AH{sub 2}) was lowered to about 20% of control by feeding rabbit chow for 2 weeks. Lung NPSH was lowered to about 50% of control by injecting a mixture of buthionine S,R-sulfoximine (BSO) and diethylmaleate (DEM) (2.7 and 1.2 mmol/kg respectively). BSO/DEM did not affect the lung concentrations of (AH{sub 2}) or alpha-tocopherol. AH{sub 2} depletion caused a 6 fold and a 3 fold enhancement in the toxicity of 5 ppm and 10 ppm (NO{sub 2}), and a 6 fold enhancement in the toxicity of 0.5 ppm (O{sub 3}), but did not affect toxicity of 1.0 ppm (O{sub 3}). AH{sub 2} depletion did not affect phosgene toxicity (at 0.25 ppm and 0.5 ppm).

    Contemporary operating environment requires a wide range of tools to respond to a myriad of regular and irregular threats. Accordingly, conventional weapons do not suffice in some cases. As technology improves exponentially, the dominance of conventional weapons is slowly fading away by the advances in laser technology. This study first outlines the characteristics of laser weapons, then provides the military applications of them in land, maritime, air and space domains and finally exhibits implications for battlefield functions. This study concludes that any country that is seeking primacy in military terms must allocate extra time and resources to obtain this emerging technology. Since it seems that there are not adequate studies about the military applications and operational concepts of the laser weapons, this study tries to increase awareness about their potential advantages.

    Wars previously being executed at land and sea have also become applicable in air and space due to the advancements of aircraft and satellite systems. Rapid improvements in information technologies have triggered the concept of cyberspace which is considered as the fifth dimension of war. While transferring information quickly from physical area to electronic/digital area, cyberspace has caused to emerge a lot of threats and methods like cyber-attack, cyber-crime, cyber war which are spreading too rapidly. Individuals, institutions and establishments have begun to take their own cyber security precautions to cope with these threats. This study gives information about the concepts and advances on cyberspace in order to raise comprehensive awareness. The study also focuses on the effects of these improvements in the battlefield, and analyzes them.

    Critically injured combat casualties are rapidly evacuated from the battlefield, and within hours of their injuries they begin a 7000-mile journey home, often arriving in the United States within 7 days. National Naval Medical Center in Bethesda, Maryland, is a major facility for wounded warrior care in the Military Health System. Throughout the facility, the staff from a variety of disciplines and all military services provides care for military personnel with injuries and illnesses, with the goal of optimizing recovery and quality of life. The foundational evidence for select aspects of this care is discussed. Innovations in training and care delivery include the Air Force Nurse Corps' Critical Care Fellowship, the new inpatient Traumatic Brain Injury Unit, and the National Intrepid Center for Excellence for Traumatic Brain Injury and Psychological Health. The future of the Medical Center includes a new name, expanded staff, and newly constructed space by Department of Defense Base Realignment and Closure activities. PMID:20683232

    Toxic industrial chemicals e.g., phosgene, are widely used as reactive intermediates in industrial processes. Inhalation exposure to these chemicals can result in life-threatening acute lung injury (ALI), to which no specific antidote exists. This study aimed to assess the potential benefit of steroids in treating phosgene induced ALI. Anesthetized pigs were instrumented, exposed to phosgene Ct 2000 mg.min.m(-3) (Ct is the product of concentration [mg.m(-3)] x time [min]), and ventilated with intermittent positive pressure ventilation before being randomized to study part 1: treatment with intravenous glucose saline (20 mL) or methylprednisolone (12.5 mg.kg(-1) in 20 mL) 6 h postexposure or study part 2: treatment with inhaled glucose saline (2 mL) or budesonide (2 mL of 0.5 mg.mL(-1) solution) at 1, 6, 12, and 18 h postexposure. Biochemical parameters and animal physiology were monitored to 24 h postexposure. The results show no change in mortality, lung edema, or shunt fraction; however, some beneficial effects on cardiac parameters e.g., stroke volume, left ventricular stroke work, were noted. Steroids were neither beneficial nor detrimental in the treatment of phosgene induced ALI. This study does not support the use of steroids alone as a treatment, but their use in a combined therapy strategy should be investigated. PMID:20055070

  16. The fate of atmospheric phosgene and the stratospheric chlorine loadings of its parent compounds: CCl4, C2Cl4, C2HCL3, CH3CCl3, and CHCl3

    A study of the tropospheric and stratospheric cycles of phosgene is carried out to determine its fate and ultimate role in controlling the ozone depletion potentials of its parent compounds. Tropospheric phosgene is produced from the OH-initiated oxidation of C2Cl4, CH3CCl3, CHCl3, and C2HCl3. Simulations using a two-dimensional model indicate that these processes produce about 90 pptv/yr of tropospheric phosgene with an average concentration of about 18 pptv, in reasonable agreement with observations. We estimate a residence time of about 70 days for tropospheric phosgene, with the vast majority being removed by hydrolysis in cloudwater. Only about 0.4% of the phosgene produced in the troposphere avoids wet removal and is transported to the stratosphere, where its chlorine can be released to participate in the catalytic destruction of ozone. Stratospheric phosgene is produced from the photochemical degradation of CCl4, C2Cl4, CHCl3, and CH3CCl3 and is removed by photolysis and downward transport to the troposphere. Model calculations, in good agreement with observations, indicate that these processes produce a peak stratospheric concentration of about 25-30 pptv at an altitude of about 25 km. In contrast to tropospheric phosgene, stratospheric phosgene is found to have a lifetime against photochemical removal of the order of years. As a result, a significant portion of the phosgene that is produced in the stratosphere is ultimately returned to the troposphere, where it is rapidly removed by clouds. This phenomenon effectively decreases the amount of reactive chlorine injected into the stratosphere and available for ozone depletion from phosgene's parent compounds. A similar phenomenon due to the downward transport of stratospheric COFCl produced from CFC-11 is estimated to cause a 7% decrease in the amount of reactive chlorine injected into the stratosphere from this compound. Our results are potentially sensitive to a variety of parameters, most notably the rate

    Phosgene is an important high-production-volume intermediate with widespread industrial use. Consistent with other lung irritants causing ALI (acute lung injury), mode-of-action-based countermeasures remain rudimentary. This study was conducted to analyze whether extremely short high-level exposure to phosgene gas could be mitigated using three different inhaled nucleophiles administered by inhalation instantly after exposure to phosgene. Groups of young adult male Wistar rats were acutely exposed to carbonyl chloride (phosgene) using a directed-flow nose-only mode of exposure of 600 mg/m³ for 1.5 min (225 ppm × min). Immediately after exposure to phosgene gas the rats were similarly exposed to three strong nucleophiles with and without antioxidant properties for 5 or 15 min. The following nucleophiles were used: hexamethylenetetramine (HMT), l-cysteine (Cys), and l-glutathione (GSH). The concentration of the aerosol (mass median aerodynamic diameter 1.7-2 µm) was targeted to be in the range of 1 mg/L. Cys and GSH have antioxidant properties in addition. The calculated alveolar molar dosage of phosgene was 9 µmol/kg. At 15-min exposure duration, the respective inhaled dose of HMT, Csy, and GSH were 111, 103, and 46 µmol/kg, respectively. The alveolar dose of drugs was ~10-times lower. The efficacy of treatment was judged by protein concentrations in bronchoalveolar lavage fluid (BALF) collected 1 day post-exposure. In spite of using optimized aerosolization techniques, none of the nucleophiles chosen had any mitigating effect on BALF-protein extravasation. This finding appear to suggest that inhaled phosgene gas acylates instantly nucleophilic moieties at the site of initial deposition and that the resultant reaction products can not be reactivated even following instant inhalation treatment with competing nucleophilic agents. In spite of using maximal technically attainable concentrations, it appears to be experimentally challenging to deliver

    2016-07-01

    Although Ernest Shackleton's Endurance Antarctic expedition of 1914 to 1916 is a famous epic of survival, the medical achievements of the two expedition doctors have received little formal examination. Marooned on Elephant Island after the expedition ship sank, Drs. Macklin and McIlroy administered a chloroform anesthetic to crew member Perce Blackborow to amputate his frostbitten toes. As the saturated vapor pressure of chloroform at 0°C is 71.5 mmHg and the minimum alveolar concentration is 0.5% of sea-level atmospheric pressure (3.8 mmHg), it would have been feasible to induce anesthesia at a low temperature. However, given the potentially lethal hazards of a light chloroform anesthetic, an adequate and constant depth of anesthesia was essential. The pharmacokinetics of the volatile anesthetic, administered via the open-drop technique in the frigid environment, would have been unfamiliar to the occasional anesthetist. To facilitate vaporization of the chloroform, the team burned penguin skins and seal blubber under overturned lifeboats to increase the ambient temperature from -0.5° to 26.6°C. Chloroform degrades with heat to chlorine and phosgene, but buildup of these poisonous gases did not occur due to venting of the confined space by the stove chimney. The anesthetic went well, and the patient-and all the ship's crew-survived to return home. PMID:27148920

    A workshop was held February 14, 2007, in Arlington, VA, under the auspices of the Phosgene Panel of the American Chemistry Council. The objective of this workshop was to convene inhalation toxicologists and medical experts from academia, industry and regulatory authorities to critically discuss past and recent inhalation studies of phosgene in controlled animal models. This included presentations addressing the benefits and limitations of rodent (mice, rats) and nonrodent (dogs) species to study concentration x time (C x t) relationships of acute and chronic types of pulmonary changes. Toxicological endpoints focused on the primary pulmonary effects associated with the acute inhalation exposure to phosgene gas and responses secondary to injury. A consensus was reached that the phosgene-induced increased pulmonary extravasation of fluid and protein can suitably be probed by bronchoalveolar lavage (BAL) techniques. BAL fluid analyses rank among the most sensitive methods to detect phosgene-induced noncardiogenic, pulmonary high-permeability edema following acute inhalation exposure. Maximum protein concentrations in BAL fluid occurred within 1 day after exposure, typically followed by a latency period up to about 15 h, which is reciprocal to the C x t exposure relationship. The C x t relationship was constant over a wide range of concentrations and single exposure durations. Following intermittent, repeated exposures of fixed duration, increased tolerance to recurrent exposures occurred. For such exposure regimens, chronic effects appear to be clearly dependent on the concentration rather than the cumulative concentration x time relationship. The threshold C x t product based on an increased BAL fluid protein following single exposure was essentially identical to the respective C x t product following subchronic exposure of rats based on increased pulmonary collagen and influx of inflammatory cells. Thus, the chronic outcome appears to be contingent upon the acute

    Cyanide poisoning has existed for centuries. In most cases, cyanide is combined with other toxic substances; for example with carbon monoxide in fire smoke. Cases of pure cyanide poisoning are rare, and usually due to accidental exposure. Their treatment is based on oxygenation and the infusion of hydroxocobalamin. The seriousness of this type of poisoning calls for a rapid and specific response, which demonstrates the usefulness of non-hospital based medical treatment. The authors report here the case of a man who was the victim of occupational poisoning with sodium cyanide and who was treated at the workplace by fire-fighters and the Service Mobile d’Urgence et Reanimation emergency ambulance service.

    Over 220 U.S. Army orthopaedic surgeons have deployed during the Global War on Terrorism (GWOT). This study documents the orthopaedic procedures performed during the GWOT and identifies training that prepared surgeons for deployment. It reveals deficiencies in surgeons' preparedness and intends to improve predeployment training. All surgeons deployed during the GWOT from 2001 to 2007 were surveyed. Questions fit 4 general categories: deployment demographics, medical and surgical experiences, predeployment preparation, and self-perceived preparedness during deployment. Response rate was 70%. Surgeons averaged 138 adult operative cases and 26 pediatric cases per deployment. All surgeons performed irrigation and debridement, 94% external fixation, 93% amputations, 89% arthrotomies, 86% open reduction and internal fixation, and 76% soft-tissue coverage procedures. Residency and fellowship contributed most to surgeon preparedness for deployment. Surgeons generally reported high levels of preparedness, but nearly 1 in 6 reported low levels of medical, surgical and physical preparedness. More reported low levels of mental preparedness. Soft-tissue coverage was the most frequently reported surgical deficiency. This study documents the number and types of orthopaedic procedures performed during the GWOT and identifies the self-perceived preparedness deficiencies of surgeons in a combat environment. Improvements in predeployment training are needed to better prepare surgeons for managing battlefield causalities. PMID:23025135

    2004-09-01

    SRICO has developed a revolutionary approach to physiological status monitoring using state-of-the-art optical chip technology. The company"s patent pending Photrode is a photonic electrode that uses unique optical voltage sensing technology to measure and monitor electrophysiological parameters. The optical-based monitoring system enables dry-contact measurements of EEG and ECG signals that require no surface preparation or conductive gel and non-contact measurements of ECG signals through the clothing. The Photrode applies high performance optical integrated circuit technology, that has been successfully implemented in military & commercial aerospace, missile, and communications applications for sensing and signal transmission. SRICO"s award winning Photrode represents a new paradigm for the measurement of biopotentials in a reliable, convenient, and non-intrusive manner. Photrode technology has significant applications on the battlefield for rapid triage to determine the brain dead from those with viable brain function. An ECG may be obtained over the clothing without any direct skin contact. Such applications would enable the combat medic to receive timely medical information and to make important decisions regarding identification, location, triage priority and treatment of casualties. Other applications for the Photrode include anesthesia awareness monitoring, sleep medicine, mobile medical monitoring for space flight, emergency patient care, functional magnetic resonance imaging, various biopotential signal acquisition (EMG, EOG), and routine neuro and cardio diagnostics.

    CO is an ubiquitous poison with many sources of exposure. CO poisoning produces diverse signs and symptoms that are often subtle and may be easily misdiagnosed. Failure to diagnose CO poisoning may result insignificant morbidity and mortality and permit continued exposure to a dangerous environment. Treatment of CO poisoning begins with inhalation of supplemental oxygen and aggressive supportive care. HBOT accelerates dissociation of CO from hemoglobin and may also prevent DNS. Absolute indications forHBOT for CO poisoning remain controversial, although most authors would agree that HBOT is indicated in patients who are comatose or neurologically abnormal, have a history of LOC with their exposure, or have cardiac dysfunction. Pregnancy with an elevated CO-Hgb level(>15%-20%) is also widely, considered an indication for treatment.HBOT may be considered in patients who have persistent symptoms despite NBO, metabolic acidosis, abnormalities on neuropsychometric testing, or significantly elevated levels. The ideal regimen of oxygen therapy has yet to be determined, and significant controversy exists regarding HBOTtreatment protocols. Often the local medical toxicologist, poison control center, or hyperbaric unit may assist the treating physician with decisions regarding therapy. PMID:16227059

    CO is an insidious poison with many sources of exposure. CO poisoning produces diverse signs and symptoms, which often are subtle and can be misdiagnosed easily. Failure to diagnose CO poisoning may result insignificant morbidity and mortality and allow continued exposure to a dangerous environment. In the ED, a high index of suspicion must be maintained for occult CO exposure. Headache, particularly when associated with certain environments, and flulike illness in the wintertime with symptomatic cohabitants should raise the index of suspicion in the ED significantly for occult CO poisoning. Emergency treatment of CO poisoning begins with inhalation of supplemental oxygen and aggressive supportive care. HBOT accelerates dissociation of CO from hemoglobin and may prevent DNS. Absolute indications for HBOT for CO poisoning remain controversial, although most would agree that HBOT is indicated in patients who are comatose, are neurologically abnormal, have a history of loss of consciousness with their exposure, or have cardiac dysfunction. Pregnancy with an elevated CO-Hgb level (>15-20%) also is widely considered an indication for treatment. HBOT may be considered in patients who have persistent symptoms despite NBO, metabolic acidosis, abnormalities on neuropsychometric testing, or significantly elevated levels. The ideal regimen of oxygen therapy has yet to be determined, and significant controversy exists regarding HBOT protocols. The emergency physician may be confronted with the difficult decision regarding disposition and even transfer to a hyperbaric facility. Often the local medical toxicologist, poison control center, or hyperbaric unit can assist the emergency physician with the decision-making process. PMID:15474779

  5. Developing defensive aids suite technology on a virtual battlefield

    2002-07-01

    Modern anti-tank missiles and the requirement of rapid deployment are limiting the use of passive armour in protecting land vehicles. Vehicle survivability is becoming more dependent on sensors, computers and countermeasures to detect and avoid threats. The integration of various technologies into a Defensive Aids Suite (DAS) can be designed and analyzed by combining field trials and laboratory data with modeling and simulation. MATLAB is used as a quick prototyping tool to model DAS systems and facilitate transfer to other researchers. The DAS model can be transferred from MATLAB or programmed directly in ModSAF (Modular Semi-Automated Forces), which is used to construct the virtual battlefield. Through scripted input files, a fixed battle approach ensures implementation and analysis meeting the requirements of three different interests. These three communities include the scientists and engineers, military and operations research. This approach ensures the modelling of processes known to be important regardless of the level of information available about the system. A system can be modelled phenomenologically until more information is available. Further processing of the simulation can be used to optimize the vehicle for a specific mission. ModSAF will be used to analyze and plan trials and develop DAS technology for future vehicles. Survivability of a DAS-equipped vehicle can be assessed relative to a basic vehicle without a DAS. In later stages, more complete DAS systems will be analyzed to determine the optimum configuration of the DAS components and the effectiveness of a DAS-equipped vehicle for specific missions. These concepts and approach will be discussed in the paper.

    Arsenic poisonings are still important in the field of toxicology, though they are not as frequent as about 20-30 years ago. In this paper, the arsenic concentrations in ante- and post-mortem materials, and also forensic and anatomo-pathological aspects in three cases of massive acute poisoning with arsenic(III) oxide (two of them with unexplained criminalistic background, in which arsenic was taken for amphetamine and one suicide), are presented. Ante-mortem blood and urine arsenic concentrations ranged from 2.3 to 6.7 microg/ml, respectively. Post-mortem tissue total arsenic concentrations were also detected in large concentrations. In case 3, the contents of the duodenum contained as much as 30.1% arsenic(III) oxide. The high concentrations of arsenic detected in blood and tissues in all presented cases are particularly noteworthy in that they are very rarely detected at these concentrations in fatal arsenic poisonings.

    Boric acid poisoning in 11 infants, occurring in the newborn nursery as a result of the accidental and inadvertent use of 2.5% boric acid in the preparation of the formulae, is reported. Five of the infants died. All except two exhibited the classical symptomatology of acute boric acid poisoning, namely, diarrhea, vomiting, erythema, exfoliation, desquamation of the skin, and marked central nervous system irritation. Early manifestations of poisoning were nonspecific, and one patient died before skin manifestations were noted. Peritoneal dialysis, instituted in nine cases, was found to be the most effective method of treatment. It is recommended that boric acid, which is of doubtful therapeutic value, should be completely removed from hospitals, dispensaries and pharmacopoeias. ImagesFig. 1Fig. 2 PMID:14166459

    Carbon monoxide poisoning is a significant cause of illness and death. Its protean symptoms probably lead to a gross underestimation of its true incidence. Low levels of carbon monoxide aggravate chronic cardiopulmonary problems, and high levels are associated with cardiac arrhythmias and cerebral edema. Patients who survive acute poisoning are at risk of delayed neurologic sequelae. The measurement of carboxyhemoglobin levels does not reveal the tissue levels of carbon monoxide but is useful in determining therapy. Treatment includes the monitoring and management of cardiac arrhythmias and oxygenation. Hyperbaric oxygenation is beneficial, but there are currently no definite criteria for its use. PMID:4027805

The way of exposure, characteristic of the clinical presentation, complications and the outcome of the intoxications, as well as the therapeutic approach is described. In all of the cases combined drug intoxication with benzodiazepines and opiates have been proved. The impact of the combination of two toxic substances: the first causing rapid and brief suppression of the consciousness and the second, causing prolonged continuation of the already suppressed consciousness, on the clinical course is discussed. The similarities in the circumstances of the exposure, clinical course of the poisonings, the identified toxic substances, lead to the consideration of criminal characteristic of the poisonings. The contact with the corresponding authorities brought off the disclosure of a group of criminals, committed the intentional intoxications with the aim of robbery. Age, with all its various characteristics, has been discussed as a factor for occurrence of criminal poisonings. PMID:16225098

    Phosgene (CG), a toxic inhalation and industrial hazard, causes bronchoconstriction, vasoconstriction and associated pathological effects that could be life threatening. Ion channels of the transient receptor potential (TRP) family have been identified to act as specific chemosensory molecules in the respiratory tract in the detection, control of adaptive responses and initiation of detrimental signaling cascades upon exposure to various toxic inhalation hazards (TIH); their activation due to TIH exposure may result in broncho- and vasoconstriction. We studied changes in the regulation of intracellular free Ca(2+) concentration ([Ca(2+)]i) in cultures of human bronchial smooth muscle cells (BSMC) and human pulmonary microvascular endothelial cells (HPMEC) exposed to CG (16ppm, 8min), using an air/liquid interface exposure system. CG increased [Ca(2+)]i (p<0.05) in both cell types, The CG-induced [Ca(2+)]i was blocked (p<0.05) by two types of TRP channel blockers, SKF-96365, a general TRP channel blocker, and RR, a general TRPV (vanilloid type) blocker, in both BSMC and HPMEC. These effects correlate with the in vivo efficacies of these compounds to protect against lung injury and 24h lethality from whole body CG inhalation exposure in mice (8-10ppm×20min). Thus the TRP channel mechanism appears to be a potential target for intervention in CG toxicity. PMID:26562769

    While cyberspace is emerging as a new battlefield, conventional Electronic Warfare (EW) methods and applications are likely to change. Cyber Electronic Warfare (CEW) concept which merges cyberspace capabilities with traditional EW methods, is a new and enhanced form of the electronic attack. In this study, cyberspace domain of the battlefield is emphazised and the feasibility of integrating Cyber Warfare (CW) concept into EW measures is researched. The SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis method is used to state the operational advantages of using CEW concept in the battlefield. The operational advantages of CEW are assessed by means of its effects on adversary air defense systems, communication networks and information systems. Outstanding technological and operational difficulties are pointed out as well. As a result, a comparison of CEW concept and conventional EW applications is presented. It is concluded that, utilization of CEW concept is feasible at the battlefield and it may yield important operational advantages. Even though the computers of developed military systems are less complex than normal computers, they are not subjected to cyber threats since they are closed systems. This concept intends to show that these closed systems are also open to the cyber threats. As a result of the SWOT analysis, CEW concept provides Air Forces to be used in cyber operations effectively. On the other hand, since its Collateral Damage Criteria (CDC) is low, the usage of cyber electronic attack systems seems to grow up.

    The warfighter of tomorrow will demand near real time multimedia data access to obtain critical information in rapidly changing battlefield situation. Phase 1 of the Battlefield Awareness and Data Dissemination (BADD) Advanced Concept Technology Demonstration (ACTD) developed a near real time multimedia data access capability to provide the warfighter with sensor and command and control data on an integrated display. The system provides both live and historical display of the multimedia products with the ability to rapidly search spatially and temporally using a powerful graphical user interface. A key development for the system is the implementation of a video server that provides rapid access to stored video that is keyed to a map showing the Unmanned Aerial Vehicle (UAV) flight path and its sensor coverage. The BADD System managed the multimedia information from field sensors and processors and utilized the Global Broadcast System (GBS) to disseminate the data to remote users. The system provides the capability to disseminate battlefield data based on user defined profiles (Smart Push) and by queries for stored products (Warfighter Pull). The research addressed the multimedia information management architecture required to meet these requirements in a near real time battlefield exercise. The BADD system interfaced with the legacy and emerging systems in Task Force (TF) XXI and Division XXI. The research also addressed the user and system issues necessary for successful field operation. The BADD system was successful in TFXXI and improvements were incorporated in Division XXI.

    An accidental poisoning due to drinking methyl alcohol in Chaoyang county is reported, analysing the accident. The poison came from the "retail white spirit" which was contaminated with methyl alcohol. Twenty-nine persons drank the wine, fourteen of them died, two of them became blind. After drinking this "retail white spirit" the drinkers showed symptoms of vertigo, headache, weakness, vomiting, night sweat, dyspnea and blurring of vision etc. within 6-120 hours. On examining the remaining spirit, we found the content of methyl alcohol to be between 16.6 and 40.69 g/100 ml. Some of the patients' urine and blood also contained methyl alcohol. We reckoned that each one of the twenty patients had taken more than 27 g of methyl alcohol and each of the ten dead drank more than 40 ml of the alcohol. PMID:2253526

    Among the human pathologies produced by venomous animals, bee stings constitute the largest number of accidents in several countries, exceeding the mortality rate caused by other venomous animals such as snakes, spiders or scorpions. The clinical picture after the bee sting may include anaphylaxis or poisoning. The latter is produced by massive attacks and is a serious problem that may put the patient's life at risk. People that are poisoned display hemolysis, rhabdomiolysis and acute renal failure that together with other systemic failures can bring about death. The knowledge of the physiopathological mechanisms involved in the massive attack of bees is crucial for health care professionals as to date we do not have antivenoms with proven clinical efficacy. In this review we include the bee's biological aspects, venom composition and its relation with the occurrence and severity of accidents as well as epidemiological data that can be useful for this type of accidents.

The mechanism of action responsible for many types of poison-induced fevers is not understood. Some elevations in body temperature are attributed to the peripheral actions of some poisons that stimulate metabolic rate and cause a forced hyperthermia. Exposure to organophosphate (OP) pesticides and certain metal fumes appears to cause a prolonged, regulated elevation in body temperature (Tb). 2. Activation of cyclo-oxygenase (COX) and the production of prostaglandin (PG)E2 in central nervous system (CNS) thermoregulatory centres is required to elicit a fever. Activating the COX-PGE2 pathway by a poison may occur by one of three mechanisms: (i) induction of cell-mediated immune responses and the subsequent release of cytokines; (ii) induction of lipid peroxidation in the CNS; and (iii) direct neurochemical activation. 3. Radiotelemetric monitoring of core temperature in unstressed rodents has led to an experimental animal model of poison-induced fever. Rats administered the OP agents chlorpyrifos and diisopropyl fluorophosphate display an initial hypothermic response lasting approximately 24 h, followed by an elevation in diurnal core temperature for 24-72 h after exposure. The hyperthermia is apparently a result of the activation of the COX-PGE2 pathway because it is blocked by the anti-pyretic sodium salicylate. Overall, the delayed hyperthermia resulting from OP exposure involves activation of thermoregulatory pathways that may be similar to infection-mediated fever. PMID:9493505

    Phostoxin is a mixture of aluminium phosphide and ammonium carbonate. When exposed to water, it releases phosphorus hydrogen (PH3), a highly-poisonous gas. In Morocco, death rate from suicide due to self-administration of phostoxin pills is high. Clinical signs include abrupt digestive and nervous disorders. Pulmonary oedema or cardiogenic shock dominate early prognosis. Liver and renal damage is secondary. Prevention requires both legal constraints and regulation of sales. PMID:7761363

    Between 3 June and 15 July 1967 four explosive outbreaks of acute poisoning with the insecticide endrin occurred in Doha in Qatar and Hofuf in Saudi Arabia. Altogether 874 persons were hospitalized and 26 died. It is estimated that many others were poisoned whose symptoms were not so severe as to cause them to seek medical care or to enter hospital. The author describes the course of the outbreaks and the measures taken to ascertain their cause and prevent their extension and recurrence. It was found that the victims had eaten bread made from flour contaminated with endrin. In two different ships, both of them loaded and off-loaded at different ports, flour and endrin had been stowed in the same hold, with the endrin above the flour. In both ships the endrin containers had leaked and penetrated the sacks of flour which was later used to make bread. These two unconnected but nearly simultaneous mass poisonings emphasize the importance of regulating the carriage of insecticides and other toxic chemicals in such a way as to prevent the contamination of foodstuffs and similar substances during transport; both the World Health Organization and the Inter-Governmental Maritime Consultative Organization are working towards the establishment of regulations and practices to that end.

    Aluminum phosphide (AlP) is a cheap, effective and commonly used pesticide. However, unfortunately, it is now one of the most common causes of poisoning among agricultural pesticides. It liberates lethal phosphine gas when it comes in contact either with atmospheric moisture or with hydrochloric acid in the stomach. The mechanism of toxicity includes cellular hypoxia due to the effect on mitochondria, inhibition of cytochrome C oxidase and formation of highly reactive hydroxyl radicals. The signs and symptoms are nonspecific and instantaneous. The toxicity of AlP particularly affects the cardiac and vascular tissues, which manifest as profound and refractory hypotension, congestive heart failure and electrocardiographic abnormalities. The diagnosis of AlP usually depends on clinical suspicion or history, but can be made easily by the simple silver nitrate test on gastric content or on breath. Due to no known specific antidote, management remains primarily supportive care. Early arrival, resuscitation, diagnosis, decrease the exposure of poison (by gastric lavage with KMnO4, coconut oil), intensive monitoring and supportive therapy may result in good outcome. Prompt and adequate cardiovascular support is important and core in the management to attain adequate tissue perfusion, oxygenation and physiologic metabolic milieu compatible with life until the tissue poison levels are reduced and spontaneous circulation is restored. In most of the studies, poor prognostic factors were presence of acidosis and shock. The overall outcome improved in the last decade due to better and advanced intensive care management.

    1. Oxygen in concentrations of over 70 per cent of an atmosphere is poisonous to dogs, rabbits, guinea pigs and mice. 2. The poisonous effects manifest themselves in drowsiness, anorexia, loss of weight, increasing dyspnea, cyanosis and death from oxygen want. 3. The cause of oxygen want is a destructive lesion of the lungs. 4. The lesion may be characterized grossly as an hemorrhagic edema. Microscopically there is to be seen in varying degrees of intensity (a) capillary engorgement with hemorrhage, (b) the presence of interstitial and intraalveolar serum, (c) hypertrophy and desquamation of alveolar cells, (d) interstitial and alveolar infiltration of mononuclear cells. 5. The type of tissue reaction is not characteristic of an infectious process and no organisms have been recovered at autopsy from the heart's blood or from lung puncture. 6. The poisonous effects of inhalations of oxygen-rich mixtures do not appear to be related to impurities in the oxygen, nor are they related to faulty ventilation, excessive moisture or increased carbon dioxide in the atmosphere of the chambers in which the experimental animals were confined.

    2014-08-01

    Poisons have long been used to kill wildlife throughout the world. An evolution has occurred from the use of plant- and animal-based toxins to synthetic pesticides to kill wildlife, a method that is silent, cheap, easy, and effective. The use of pesticides to poison wildlife began in southern Africa, and predator populations were widely targeted and eliminated. A steep increase has recently been observed in the intensity of wildlife poisonings, with corresponding population declines. However, the majority of poisonings go unreported. Under national laws, it is illegal to hunt wildlife using poisons in 83% of African countries. Pesticide regulations are inadequate, and enforcement of existing legislation is poor. Few countries have forensic field protocols, and most lack storage and testing facilities. Methods used to poison wildlife include baiting carcasses, soaking grains in pesticide solution, mixing pesticides to form salt licks, and tainting waterholes. Carbofuran is the most widely abused pesticide in Africa. Common reasons for poisoning are control of damage-causing animals, harvesting fish and bushmeat, harvesting animals for traditional medicine, poaching for wildlife products, and killing wildlife sentinels (e.g., vultures because their aerial circling alerts authorities to poachers' activities). Populations of scavengers, particularly vultures, have been decimated by poisoning. Recommendations include banning pesticides, improving pesticide regulations and controlling distribution, better enforcement and stiffer penalties for offenders, increasing international support and awareness, and developing regional pesticide centers.

    Carbamate insecticide is a leading cause of poisoning in Thailand. The objective of this study was to characterize the clinical manifestations and modes of occupational exposure in carbamate poisoning cases. We retrospectively studied all the cases of carbamate poisoning due to occupational exposure recorded in the Ramathibodi Poison Center Toxic Exposure Surveillance system during 2005 to 2010. Demographic data, clinical manifestations and severity were analyzed statistically. During the study period, 3,183 cases were identified, of which 170 (5.3%) were deemed to be due to occupational exposure. Ninety-six cases (56.5%) and 35 cases (20.6%) were poisoned by carbofuran and methomyl, respectively. Carbofuran is sold as a 3% grain and applied by sowing; methomyl is sold as a liquid and is applied by spraying. The majority of poisoned patients did not wear personal protective equipment (PPE) while applying the carbamates. The clinical manifestations of occupational carbofuran poisoning recorded were nausea and vomiting (82.3%), headaches (56.3%) and miosis (19.8%). The clinical manifestations of methomyl poisoning were nausea and vomiting (74.3%), headaches (57.1%) and palpitations (11.4%). Most patients in both groups had mild symptoms. Only one case in each group required endotracheal intubation and mechanical ventilation support. There were no deaths and the lengths of hospitalization ranged from 2 hours to 2 days. Occupational carbamate poisoning cases in our series were mostly mild and the patients recovered quickly. There were only rare cases of serious symptoms. Lack of knowledge and inadequate PPE were the major factors contributing to occupational poisoning. Educating agricultural workers about correct precautions and pesticide use could minimize this type of poisoning. PMID:26867400

    A retrospective study was done of poisonous snakebite in Utah to determine the current epidemiology and scope of treatment, reviewing emergency department logs and other sources statewide for a 69-month period. Of 61 cases of poisonous snakebite identified, 13 occurred in snake hobbyists or venom laboratory personnel and were considered nonaccidental, and 48 were inflicted by native noncaptive snakes. These bites were considered accidental, and all were presumed to be from rattlesnakes. Nearly three fourths of the victims were male, ranging in age from 2 to 56 years (mean, 22 years). Most accidental bites occurred in areas of high human populations, during the summer months, in the afternoon or evening hours, and during recreational activities. Of the 48 bites, 11 (23%) were provoked. Two thirds of bites were on the upper extremities, and a third were on the lower extremities. More than half of the victims had no first-aid treatment recorded. Of those who did receive first aid, many were subjected to possibly harmful treatments, including tourniquets and ice application. The median time to a hospital was 68 minutes, with a range of 15 to 440 minutes. Swelling and discoloration were the most common signs and pain and paresthesia the most common symptoms. Half the bites resulted in minimal or no envenomation, 17 (35%) produced moderate envenomation, and 6 (12%) severe envenomation. Most patients with moderate or severe envenomation received antivenin, but the dosages given were usually less than recommended dosages. Five patients received surgical treatment based on clinical findings. One child died in a snake-handling incident. Long-term morbidity was unknown due to lack of follow-up. The Utah Poison Control Center was poorly utilized as a reporting and informational resource. PMID:8553638

    Scombroid poisoning is a common cause of food poisoning worldwide. It is caused by ingestion of oily fish contaminated with bacteria that trigger the formation of high concentrations of histamine. Scombroid poisoning manifests mainly as a skin complaint (flushing that spreads downward and/or an erythematous urticarial rash affecting the face and upper trunk). Although the clinical course is usually self-limiting and benign, vascular compromise, bronchospasm, and arrhythmias have been described. It is important to establish a differential diagnosis that includes conditions such as fish allergy. Oral antihistamines are the mainstay of treatment. Scombroid poisoning is best prevented by refrigerating fish properly. The practical review of scombroid poisoning provided here is intended for dermatologists. PMID:27133773

    Over a period of years interested individuals have submitted many dead or moribund herons of various species to our laboratory to learn whether the birds had been affected by diseases or organochlorine poisoning. Residue concentrations in carcasses of birds and mammals are considered the best measure of sublethal exposure, whereas residues in brains are best to use for diagnosing death by most organochlorine chemicals.... The purpose of the present paper is to document the occurrence and concentration of organochlorine residues in the brains of herons from various areas in the United States. By comparing these residue concentrations with laboratory-determined diagnostic lethal levels, we conclude that some herons were killed by organochlorine poisoning; others were at least seriously endangered by the residues they carried. Complete results of carcass analyses for these and other herons, as well as further details? on residues in brains, will be reported elsewhere. Overall, we analyzed carcasses or brains of more than 70 herons found dead or moribund and 36 others taken in planned collections. Residue levels in carcasses of many herons were not high enough to warrant analysis of brains. In the present paper we compare carcass and brain residues of dieldrin in 23 herons of which both carcass and brain were analyzed.

    The high-resolution absorption spectra of phosgene (Cl2CO) has been recorded at 0.001 cm-1 resolution in the 250-350 cm-1 region by Fourier transform spectroscopy at synchrotron SOLEIL. To reduce the spectral congestion, the spectra have been recorded at low temperature (197 K) using a 93.14 m optical path length cryogenic cell. This enables the first detailed infrared analysis of the ν3 bands of the 35Cl2CO and 35Cl37ClCO isotopologues of phosgene. Using a Watson-type Hamiltonian, it was possible to reproduce the upper state rovibrational infrared energy levels, together with, for 35Cl2CO, the available microwave data in the 31 excited state (Yamamoto et al. 1984) to within their experimental accuracy. In this way, accurate rotational and centrifugal distortion constants together with the following band centers: ν0(ν3, 35Cl2CO) = 301.545622(17) cm-1 and ν0(ν3, 35Cl37ClCO) = 298.199194(81) cm-1, were derived for the ν3 bands of 35Cl2CO and 35Cl37ClCO.

    The use of chemical and biological weapons on the battlefield is considered by most commentators--and by international law--as more abhorrent than the use of nearly all other weapons, including ones meant either to kill secretly or to kill terribly, as do fire or burial alive. I ask why this is so. I explore this question through the study of imagery patterns in Western literature and campaigns against food contamination and environmental pollution. I find that the norm against chemical and biological weapons builds upon a taboo against poisons, a prohibition widely accepted in military manuals as distinguishing soldierly conduct from criminal conduct, especially those forms of conduct made criminal by the employment of treachery, invisibility, and transformation.

    Mittal, Sachin; Rani, Yashoda

    2015-01-01

    Aluminium phosphide (AlP) is a cheap solid fumigant and a highly toxic pesticide which is commonly used for grain preservation. AlP has currently aroused interest with a rising number of cases in the past four decades due to increased use for agricultural and non-agricultural purposes. Its easy availability in the markets has increased also its misuse for committing suicide. Phosphine inhibits cellular oxygen utilization and can induce lipid peroxidation. Poisoning with AlP has often occurred in attempts to commit suicide, and that more often in adults than in teenagers. This is a case of suicidal consumption of aluminium phosphide by a 32-year-old young medical anesthetist. Toxicological analyses detected aluminium phosphide. We believe that free access of celphos tablets in grain markets should be prohibited by law. PMID:27486362

    Hair dye poisoning is not rare but is an emerging poisoning in India. The main component of hair dye causing toxicity is paraphenylenediamine (PPD). Acute poisoning by PPD causes characteristic severe angioedema of the upper airway accompanied by a swollen, dry, hard, and protruding tongue. Systemic intoxication results in multisystem involvement and can cause rhabdomyolysis, acute renal failure (ARF). PPD consumption is an uncommon cause of ARF. There is no specific antidote for PPD and treatment is mainly supportive. We report a case of suicidal ingestion of hair dye that presented with cervicofascial edema and later developed rhabdomyolysis and ARF. Our patient improved with dialysis and symptomatic management.

    2012-01-01

    Purpose There are more drug overdose deaths in the Untied States than motor vehicle fatalities. Yet the US vital statistics reporting system is of limited value because the data are delayed by four years. Poison centers report data within an hour of the event, but previous studies suggested a small proportion of poisoning deaths are reported to poison centers (PC). In an era of improved electronic surveillance capabilities, exposure calls to PCs may be an alternate indicator of trends in overdose mortality. Methods We used PC call counts for methadone that were reported to the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS®) System in 2006 and 2007. US death certificate data were used to identify deaths due to methadone. Linear regression was used to quantify the relationship of deaths and poison center calls. Results Compared to decedents, poison center callers tended to be younger, more often female, at home and less likely to require medical attention. A strong association was found with PC calls and methadone mortality (b = 0.88, se = 0.42, t = 9.5, df = 1, p<0.0001, R2 = 0.77). These findings were robust to large changes in a sensitivity analysis assessing the impact of underreporting of methadone overdose deaths. Conclusions Our results suggest that calls to poison centers for methadone are correlated with poisoning mortality as identified on death certificates. Calls received by poison centers may be used for timely surveillance of mortality due to methadone. In the midst of the prescription opioid overdose epidemic, electronic surveillance tools that report in real-time are powerful public health tools. PMID:22829925

    Objective To determine the association between the frequencies of pharmaceutical exposures reported to a poison control center (PCC) and those seen in the emergency department (ED). Design A statewide population-based retrospective comparison of frequencies of ED pharmaceutical poisonings with frequencies of pharmaceutical exposures reported to a regional PCC. ED poisonings, identified by International Classification of Diseases, Version 9 (ICD-9) codes, were grouped into substance categories. Using a reproducible algorithm facilitated by probabilistic linkage, codes from the PCC classification system were mapped into the same categories. A readily identifiable subset of PCC calls was selected for comparison. Measurements Correlations between frequencies of quarterly exposures by substance categories were calculated using Pearson correlation coefficients and partial correlation coefficients with adjustment for seasonality. Results PCC reported exposures correlated with ED poisonings in nine of 10 categories. Partial correlation coefficients (rp) indicated strong associations (rp>0.8) for three substance categories that underwent large changes in their incidences (opiates, benzodiazepines, and muscle relaxants). Six substance categories were moderately correlated (rp>0.6). One category, salicylates, showed no association. Limitations Imperfect overlap between ICD-9 and PCC codes may have led to miscategorization. Substances without changes in exposure frequency have inadequate variability to detect association using this method. Conclusion PCC data are able to effectively identify trends in poisonings seen in EDs and may be useful as part of a pharmaceutical poisoning surveillance system. The authors developed an algorithm-driven technique for mapping American Association of Poison Control Centers codes to ICD-9 codes and identified a useful subset of poison control exposures for analysis.

    The amount of data processed annually over the Internet has crossed the zetabyte boundary, yet this Big Data cannot be efficiently processed or stored using today's mobile devices. Parallel to this explosive growth in data, a substantial increase in mobile compute-capability and the advances in cloud computing have brought the state-of-the- art in mobile-cloud computing to an inflection point, where the right architecture may allow mobile devices to run applications utilizing Big Data and intensive computing. In this paper, we propose the MObile Cloud-based Hybrid Architecture (MOCHA), which formulates a solution to permit mobile-cloud computing applications such as object recognition in the battlefield by introducing a mid-stage compute- and storage-layer, called the cloudlet. MOCHA is built on the key observation that many mobile-cloud applications have the following characteristics: 1) they are compute-intensive, requiring the compute-power of a supercomputer, and 2) they use Big Data, requiring a communications link to cloud-based database sources in near-real-time. In this paper, we describe the operation of MOCHA in battlefield applications, by formulating the aforementioned mobile and cloudlet to be housed within a soldier's vest and inside a military vehicle, respectively, and enabling access to the cloud through high latency satellite links. We provide simulations using the traditional mobile-cloud approach as well as utilizing MOCHA with a mid-stage cloudlet to quantify the utility of this architecture. We show that the MOCHA platform for mobile-cloud computing promises a future for critical battlefield applications that access Big Data, which is currently not possible using existing technology.

  5. Neurotoxic shellfish poisoning.

    PubMed

    2008-01-01

    Neurotoxic shellfish poisoning (NSP) is caused by consumption of molluscan shellfish contaminated with brevetoxins primarily produced by the dinoflagellate, Karenia brevis. Blooms of K. brevis, called Florida red tide, occur frequently along the Gulf of Mexico. Many shellfish beds in the US (and other nations) are routinely monitored for presence of K. brevis and other brevetoxin-producing organisms. As a result, few NSP cases are reported annually from the US. However, infrequent larger outbreaks do occur. Cases are usually associated with recreationally-harvested shellfish collected during or post red tide blooms. Brevetoxins are neurotoxins which activate voltage-sensitive sodium channels causing sodium influx and nerve membrane depolarization. No fatalities have been reported, but hospitalizations occur. NSP involves a cluster of gastrointestinal and neurological symptoms: nausea and vomiting, paresthesias of the mouth, lips and tongue as well as distal paresthesias, ataxia, slurred speech and dizziness. Neurological symptoms can progress to partial paralysis; respiratory distress has been recorded. Recent research has implicated new species of harmful algal bloom organisms which produce brevetoxins, identified additional marine species which accumulate brevetoxins, and has provided additional information on the toxicity and analysis of brevetoxins. A review of the known epidemiology and recommendations for improved NSP prevention are presented. PMID:19005578

    Over a six-week period a 60-year-old patient had several unexplained intoxication-like episodes. He finally had severe abdominal cramps with changes in the level of consciousness and oligoanuric renal failure (creatinine 4.7 mg/dl). The history, marked metabolic acidosis (pH 7.15, HCO3- 2.2 mmol/l, pCO2 6.6 mmHg) as well as raised anion residue (43 mmol/l) and the presence of oxalates in urine suggested poisoning by ethylene glycol contained in antifreeze liquid. Intensive haemodialysis adequately eliminated ethylene glycol and its toxic metabolites (glycol aldehyde, glycolic acid). Renal function returned within 10 days, although the concentrating power of the kidney remained impaired for several weeks because of interstitial nephritis. The intoxication had been caused by a defective heating-pipe system from which the antifreeze had leaked into the hot-water boiler (the patient had habitually prepared hot drinks by using water from the hot-water tap). Gas chromatography demonstrated an ethylene glycol concentration of 21 g per litre of water. PMID:8482240

    2013-01-01

    The Carbon Dioxide Reduction Assembly (CRA) on the International Space Station (ISS) has been operational since 2010. The CRA uses a Sabatier reactor to produce water and methane by reaction of the metabolic CO2 scrubbed from the cabin air and the hydrogen byproduct from the water electrolysis system used for metabolic oxygen generation. Incorporating the CRA into the overall air revitalization system has facilitated life support system loop closure on the ISS reducing resupply logistics and thereby enhancing longer term missions. The CRA utilizes CO2 which has been adsorbed in a 5A molecular sieve within the Carbon Dioxide Removal Assembly, CDRA. There is a potential of compounds with molecular dimensions similar to, or less than CO2 to also be adsorbed. In this fashion trace contaminants may be concentrated within the CDRA and subsequently desorbed with the CO2 to the CRA. Currently, there is no provision to remove contaminants prior to entering the Sabatier catalyst bed. The risk associated with this is potential catalyst degradation due to trace organic contaminants in the CRA carbon dioxide feed acting as catalyst poisons. To better understand this risk, United Technologies Aerospace System (UTAS) has teamed with MSFC to investigate the impact of various trace contaminants on the CRA catalyst performance at relative ISS cabin air concentrations and at about 200/400 times of ISS concentrations, representative of the potential concentrating effect of the CDRA molecular sieve. This paper summarizes our initial assessment results.

    Summary In crisis situations, such as transportation catastrophes, terrorist attacks or contamination with chemical warfare agents, it is crucial to properly organize and sensibly conduct rescue operations. Among chemical warfare agents, the most toxic ones are the derivatives of organophosphorus compounds. An individual auto-injector kit ‘IZAS-05’ contains auto-injectors, which are devices designed for intramuscular administration of drugs in self-aid or buddy-aid on the battlefield. This paper describes in detail the components of the ‘IZAS-05’ kit, as well as its mode of use and possible contraindications. PMID:22207129

    Findings are presented from the first year of a joint project between the U.S. Army Engineer Research and Development Center, the U.S. Army Research Laboratory, and the Sandia National Laboratories. The purpose of the project is to develop a finite-difference, time-domain (FDTD) capability for simulating the acoustic signals received by battlefield acoustic sensors. Many important effects, such as scattering from trees and buildings, interactions with dynamic atmospheric wind and temperature fields, and nonstationary target properties, can be accommodated by the simulation. Such a capability has much potential for mitigating the need for costly field data collection and furthering the development of robust identification and tracking algorithms. The FDTD code is based on a carefully derived set of first-order differential equations that is more general and accurate than most current sound propagation formulations. For application to three-dimensional problems of practical interest in battlefield acoustics, the code must be run on massively parallel computers. Some example computations involving sound propagation in a moving atmosphere and propagation in the presence of trees and barriers are presented.

  13. Development of a lightweight portable ventilator for far-forward battlefield combat casualty support

    Immediate medical provision substantially reduces the number of fatalities sustained during military operations. However, the shift from large-scale regional conflicts to smaller peacekeeping and humanitarian missions has reduced the military medical support infrastructure. Civilian emergency medical services have long emphasized the 'golden hour' during which a patient must receive definitive medical attention. Without on-scene medical support, injured soldiers must be transported significant distances before receiving advanced medical care, and rapid transport to a medical facility is not always a viable option. Technological solutions enable military medics to deliver advanced medical care on the battlefield. We report here on the development of a small lightweight portable respirator for the treatment of far- forward battlefield casualties. The Far Forward Life Support System (FFLSS) utilizes a combination of COTS (commercial off the shelf) components and custom designed systems to provide ventilatory support to injured combatants. It also incorporates a small IV fluid pump and IV fluids for resuscitation. A microcompressor control system monitors both system performance and patient parameters for system control. Telemetry to a pager-like device worn by the front line medic alerts of any anomalies in ventilator or patient parameters, which will add greatly to triage decisions and resource management. Novel elements of the FLSS design include oxygen generation, low-pressure air generation, available patient suction, and the absence of any high pressure air cylinders. A prototype developed for animal testing will be described in detail as well as further design requirements for the human rated prototype.

    1993-08-01

    A descriptive epidemiologic study, conducted in Costa Rica, investigated the incidence of pesticide poisonings with special attention to agricultural workers and occupational exposure. Information from three national registers (occupational accident and disease reports, hospitalizations, and deaths) were used. During 1986, 1800 occupational accidents caused by pesticides were reported; between 1980 and 1986 altogether 3330 persons were hospitalized and 429 died. Cholinesterase inhibitors caused 71% of the reported occupational accidents, 63% of the hospitalizations, and 36% of the deaths. Paraquat caused 21% of the occupational accidents, 24% of the hospitalizations, and 60% of the deaths. Hospitalizations and deaths were 13 and 11 times, respectively, more frequent among agricultural workers than among the rest of the population. High-risk groups for occupational poisonings included agricultural workers aged 15-29 years, female workers, and banana plantation workers. The yearly incidence of symptomatic occupational pesticide poisonings among agricultural workers was estimated at 4.5%. PMID:8235511

    Until very recently, toxicity was not considered a trait observed in birds, but works published in the last two decades started to shed light on this subject. Poisonous birds are rare (or little studied), and comprise Pitohui and Ifrita birds from Papua New Guinea, the European quail, the Spoor-winged goose, the Hoopees, the North American Ruffed grouse, the Bronzewings, and the Red warbler. A hundred more species are considered unpalatable or malodorous to humans and other animals. The present review intends to present the current understanding of bird toxicity, possibly pointing to an ignored research field. Whenever possible, biochemical characteristics of these poisons and their effects on humans and other animals are discussed, along with historical aspects of poison discovery and evolutionary hypothesis regarding their function.

We examine here the circumstances leading up to these poisonings, along with their clinical outcomes, and propose a classification scheme based on underlying intent. PMID:10750178

    2007-09-01

    Free-space optical communication (FSOC) is used to transmit a modulated beam of light through the atmosphere for broadband applications. Fundamental limitations of FSOC arise from the environment through which light propagates. We address transmitted light signal dispersion (spatial, angular, and temporal dispersion) in FSOC that operates in the battlefield environment. Light signals (photons) transmitted through the battlefield environment will interact with particles of man-made smoke such as fog oil, along the propagation path. Photon-particle interaction causes dispersion of light signals, which has significant effects on signal attenuation and pulse spread. We show that physical properties of battlefield particles play important roles in determining dispersion of received light signals. The correlation between spatial and angular dispersion is investigated as well, which has significant effects on receiver design issues. Moreover, our research indicates that temporal dispersion (delay spread) and the received power strongly depend on the receiver aperture size, field of view (FOV), and the position of the receiver relative to the optical axis of the transmitter. The results describe only specific scenarios for given types of battlefield particles. Generalization of the results requires additional work. Based on properties of the correlation, a sensitive receiver with a small FOV is needed that can find the line-of-sight photons and work with them. PMID:17805385

  5. Is intramuscular morphine satisfying frontline medical personnels’ requirement for battlefield analgesia in Helmand Province, Afghanistan? A questionnaire study

    PubMed Central

    Gibson, Lorna M; Claydon, Michael A

    2015-01-01

    Background: All deployed British Army personnel carry intramuscular (IM) morphine auto-injectors to treat battlefield casualties. No other nation supplies parenteral opiate analgesia on individual issue. Studies highlight this agent’s inefficacy and safety issues, but are limited by a relative lack of inclusion of frontline personnel. We aimed to determine the opinions of frontline medical personnel on current battlefield analgesia. Methods: We surveyed 88 British Army frontline medical personnel (medical officers (n = 12), nurses (n = 7), combat medical technicians (CMTs) (n = 67), paramedics (n = 1) and health-care assistants (n = 1)) upon completion of a six-month deployment (September 2011 to April 2012) to Helmand Province, Afghanistan, using Likert scale questions on the efficacy of battlefield analgesia, complications of IM morphine, safety of morphine auto-injectors and its suitability for treating child casualties. Results: A total of 88/88 questionnaires were returned. Of these, 61/88 had treated casualties on the battlefield, 26/86 agreed that current battlefield analgesia is effective, 80/87 agreed that a more potent analgesic with a faster onset than IM morphine is desirable in the first hour following injury, 47/65 CMTs agreed that they can manage complications of current battlefield analgesia and 53/86 respondents correctly disagreed that current battlefield analgesia is suitable for child casualties. The potential for accidental self-injection was reported. Conclusions: A more potent, faster onset analgesic than IM morphine is desirable in the first hour following injury. Pre-deployment training should emphasise management of complications of opiate analgesics and treatment of child casualties. Oral transmucosal fentanyl citrate is now being issued to all frontline medical personnel. IM morphine will remain on individual issue to all deployed soldiers for environments where an oral agent is not suitable, for example, chemical, biological

    Organophosphorus (OP) pesticide self-poisoning is a major clinical and public health problem across much of rural Asia and responsible for two thirds of suicidal deaths. However, clinical reports or evidence for the management of mixed poisoning are lacking. Patients are often treated based on the type of symptoms they exhibit, and there are no specific guidelines available to treat mixed poisoning. In this case series, we report 3 acute OP poisoning cases with mixed poisons such as organochlorine, fungicide, copper sulfate, and kerosene. All 3 patients were treated successfully, with a greater focus on OP poisoning with pralidoxime and atropine infusion along with standard decontamination procedures. Because patients developed complications due to the concomitant poisons ingested, they were later treated symptomatically, and in one case, D-penicillamine was administered as antidote for copper poisoning. Mixed poisoning especially with OP compounds makes the diagnosis difficult because the clinical symptoms of OP predominate, whereas damage produced by other pesticides is late to develop and often neglected. Common treatment procedures are focused mainly on the OP poisoning ignoring the complications of other concomitant pesticides ingested. Treating physicians should be prepared and consider the possibility of mixed poisoning prevalent in that region before initiating therapy. PMID:19497478

    Amitraz is used as an ectoparasiticide for dogs and cattle. Human poisoning due to amitraz may be misdiagnosed as organophosphate/carbamate (OPC) toxicity, since amitraz poisoning shares several clinical features (miosis, bradycardia and hypotension) encountered with OPC poisoning. A 19-year-old man with an alleged history of suicidal ingestion of a pesticide presented with drowsiness and was found to have constricted pupils, hypotension and bradycardia. He was diagnosed as a case of OPC poisoning and was treated with atropine and pralidoxime prior to presentation to our centre. Absence of a hypersecretory state, and the presence of hyperglycaemia and hypothermia along with a normal serum cholinesterase level suggested an alternate possibility. Retrieval of the poison container confirmed the diagnosis of amitraz poisoning. The patient made a rapid recovery with supportive management. Clinician awareness is key to successful management of this poisoning, which carries a good prognosis. PMID:26430228

    The Army Physical Evaluation Board results for wounded warriors from a previously described cohort were reviewed to identify permanently disabling conditions and whether the conditions were preexisting or caused by battlefield injury. Arthritis was the most common unfitting condition in this cohort, with 94.4% of cases attributed to combat injury and only 5.6% attributed to preexisting conditions or documented in the health records prior to battle injury. The most common causes of injury that resulted in arthritis were intra-articular fractures secondary to explosions, traumatic arthrotomies resulting from fragment projectiles, and gunshot wounds. Arthritis was recognized as a disabling condition an average of 19 ± 10 months after injury. Research is needed to enhance prevention and management of joint injuries in order to minimize the disabling effects of joint degeneration in this young patient population. PMID:22865140

    2015-09-01

    The gunshot wounds sustained on the battlefield caused by military ammunition can be different in nature to those usually encountered in the civilian setting. The main difference is that military ammunition has typically higher velocity with therefore greater kinetic energy and consequently potential to destroy tissue. The surgical priorities in the management of gunshot wounds are hemorrhage control, preventing infection, and reconstruction. The extent to which a gunshot wound needs to be surgically explored can be difficult to determine and depends on the likely amount of tissue destruction and the delay between wounding and initial surgical treatment. Factors associated with greater energy transfer, e.g., bullet fragmentation and bony fractures, are predictors of increased wound severity and therefore a requirement for more surgical exploration and likely debridement. Gunshot wounds should never be closed primarily; the full range of reconstruction from secondary intention to free tissue transfer may be required. PMID:26108862

    A mobile robotic vehicle with potential for use in military field applications is described. Based on a Sandia design intended for use in exploration of the Lunar surface, the Highly Agile Ground Assessment Robot (HAGAR) is a four wheeled all-wheel-drive dual-body vehicle. A uniquely simple method of chassis articulation is employed which allows all four wheels to remain in contact with the ground, even while operating in very rough terrain and climbing over obstacles as large as a wheel diameter. Skid steering and modular construction are used to produce a simple, rugged, lightweight, highly agile mobility chassis with a reduction in the number of parts required when compared to conventional vehicle designs for military battlefield and support missions. The design configuration, mobility parameters, potential mission configurations, and performance of existing and proposed HAGAR prototypes are discussed.

    PubMed

    Phillips, Gervase

    2011-01-01

    The increased lethality of nineteenth-century “arms of precision” caused military formations to disperse in combat, transforming the ordinary soldier from a near automaton, drilled to deliver random fire under close supervision, into a moral agent who exercised a degree of choice about where, when, and how to fire his weapon. The emerging autonomy of the soldier became a central theme in contemporary tactical debates, which struggled to reconcile the desire for discipline with the individual initiative necessary on the battlefield. This tactical conundrum offers revealing insights about human aggression and mass violence. Its dark legacy was the propagation of military values into civilian society, thus paving the way for the political soldiers of the twentieth century. PMID:21584989

    TMAP is a remotely operated battlefield system consisting of a 750-pound all terrain vehicle, remotely operated by a solider over a fiber optic communication link 4 km long. Using state-of-the-art automation and robotic technology, Martin Marietta Aero and Naval Systems is developing a modular prototype system under contract to Sandia National Laboratories. The Army Material developer is the Missile Command (MICOM) at Huntsville, Alabama; the Combat Developer is the Infantry School (USAIS) at Ft. Benning, Georgia. With the weapons removed by Congress in December 1987, the O & O is being rewritten for a ``Tactical Multipurpose Automated Platform`` (TMAP) instead of the original Teleoperated Mobile Antiarmor Platform. With minimal modification the modular TMAP system can be used in many applications (eg., antiarmor or antiair weapons, mine detection, medical support). System acceptance and Army evaluation testing is scheduled for summer and fall of 1988. 9 figs., 2 tabs.

    In the modern warfare information is the crucial key of winning. Battlefield situation awareness contributes to grasping and retaining the intelligence predominance. Due to its own special characteristics Wireless Sensor Networks (WSN) have been widely used to realize reconnaissance and surveillance in the joint operations and provide simultaneous, comprehensive, accurate data to multiechelon commanders and the combatant personnel for decision making and rapid response. Military sensors have drawn great attention in the ongoing projects which have satisfied the initial design or research purpose. As the interface of the "Internet of Things" which will have an eye on every corner of the battlespace WSNs play the necessary role in the incorporated situation awareness system. WSNs, radar, infrared ray or other means work together to acquire awareness intelligence for the deployed functional units to enhance the fighting effect.

    There is growing evidence that modern missions have added stresses and ethical complexities not seen in previous military operations and that there are links between battlefield stressors and ethical lapses. Military ethicists have concluded that the ethical challenges of modern missions are not well addressed by current military ethics educational programs. Integrating the extant research in the area, we propose that scenario-based operational ethics training in high-intensity military field training settings may be an important adjunct to traditional military ethics education and training. We make the case as to why this approach will enhance ethical operational preparation for soldiers, supporting their psychological well-being as well as mission effectiveness. PMID:25206947

    It is accepted that so long as men and women are sent into combat, some will be wounded or killed. In order to minimize those that are killed, efforts must be made to optimize medical treatment for those who are not fatally wounded. The nature of warfare is changing. The pattern of wounding is changing as well. However, what remains constant is the need to provide effective treatment as soon as possible. In war, it means acting at the level of the battlefield. To be effective demands new approaches to diagnosis and treatment. Novel diagnostic tools are needed to identify location of foreign bodies, determine extents of injury, monitor vital signs, and ascertain adequacy of resuscitation. Treatment devices that can provide hemostasis, support organ perfusion, stabilize limbs and neck and relieve a pneumothorax are lacking. Our young soldiers of tomorrow need solutions to their injuries today.

    The Baron Dominique-Jean Larrey, one of the greatest names in military surgery, participated as Chief Surgeon in all the Napoleonic campaigns. He developed the concept of early evacuation from the battlefield, and of immediate treatment of the wounded, even under fire. He implemented improved surgical techniques and improved wound care that were followed by surgeons all over Europe. His devotion to wounded soldiers crossed national boundaries and became a way of life. Here is an account of Larrey's involvement in the aftermath of the Battles of Lutzen and Bautzen (May-June 1813), when many soldiers were accused of self-mutilation and were about to be executed. He dared to oppose, singlehanded, the Emperor, the highest military authorities and their concurring physicians and surgeons, armed only by his undisputed honesty, professional authority and exceptional reputation won over years of devotion to wounded soldiers. Larrey saved the lives of many soldiers and set an example of unbent ethical integrity. PMID:10911440

    Airway management is an essential skill in providing care in trauma situations. The video laryngoscope is a tool which offers improvement in teaching airway management skills and in managing airways of trauma patients on the far forward battlefield. An Operational Assessment (OA) of videolaryngoscope technology for medical training and airway management was conducted by the Center for Advanced Technology and Telemedicine (at the University of Nebraska Medical Center, Omaha, NE) for the US Air Force Modernization Command to validate this technology in the provision of Out of OR airway management and airway management training in military simulation centers. The value for both the training and performance of intubations was highly rated and the majority of respondents indicated interest in having a video laryngoscope in their facility. PMID:21335763

    Complement system activation is recognized as a deleterious component of the mammalian physiological response to traumatic injury with severe hemorrhage (TH). Female Yorkshire swine were subjected to a simulated austere prehospital battlefield scenario. Each animal underwent controlled hemorrhage of 22 mL/kg at 100 mL/min rate for approximately 10 min followed by soft tissue injury, femur fracture, and spleen injury. Subsequent blood loss was uncontrolled. Twenty-eight minutes postinjury the animals were randomized into treatment or no treatment with recombinant human C1 esterase inhibitor (C1INH) (500 IU/kg, n = 11) and into receiving or not permissive hypotensive resuscitation (n = 14) with infusion of 45 mL/kg lactated Ringer's solution (2× blood lost). Observation and animal maintenance continued for 6 h at which time the animals had either expired or were euthanized. Heart, lung, and small intestine tissue samples were collected. Pharmacokinetic, hemodynamic, and metabolic parameters as well as survival time, plasma complement activity and tissue deposition, cytokine levels, and tissue injury were determined. We found that administration of C1INH protected tissues from damage, reduced the levels of inflammatory cytokines, and improved blood chemistry. Immunohistochemical analyses revealed that C1INH administration following TH markedly reduced complement activation and deposition in tissues. Importantly, C1INH administration prolonged survival of animals particularly in those which received resuscitation fluid infusion. Our data urge early administration of C1INH to limit organ damage and prolong survival of those injured in the battlefield. PMID:27405065

    The U.S. military uses large amounts of fuel during deployments and battlefield operations. This project sought to develop a lightweight, small form-factor, soldier-portable advanced thermoelectric (TE) system prototype to recover and convert waste heat from various deployed military equipment (i.e., diesel generators/engines, incinerators, vehicles, and potentially mobile kitchens), with the ultimate purpose of producing power for soldier battery charging, advanced capacitor charging, and other battlefield power applications. The technical approach employed microchannel technology, a unique “power panel” approach to heat exchange/TE system integration, and newly-characterized LAST (lead-antimony-silver-telluride) and LASTT (lead-antimony-silver-tin-telluride) TE materials segmented with bismuth telluride TE materials in designing a segmented-element TE power module and system. This project researched never-before-addressed system integration challenges (thermal expansion, thermal diffusion, electrical interconnection, thermal and electrical interfaces) of designing thin “power panels” consisting of alternating layers of thin, microchannel heat exchangers (hot and cold) sandwiching thin, segmented-element TE power generators. The TE properties, structurally properties, and thermal fatigue behavior of LAST and LASTT materials were developed and characterized such that the first segmented-element TE modules using LAST / LASTT materials were fabricated and tested at hot-side temperatures = 400 °C and cold-side temperatures = 40 °C. LAST / LASTT materials were successfully segmented with bismuth telluride and electrically interconnected with diffusion barrier materials and copper strapping within the module electrical circuit. A TE system design was developed to produce 1.5-1.6 kW of electrical energy using these new TE modules from the exhaust waste heat of 60-kW Tactical Quiet Generators as demonstration vehicles.

    Traditional display, control and situational awareness technologies may not allow the fighting vehicle commander to take full advantage of the rich data environment made available in the net-centric battle field of the future. Indeed, the sheer complexity and volume of available data, if not properly managed, may actually reduce crew performance by overloading or confusing the commander with irrelevant information. New techniques must be explored to understand how to present battlefield information and provide the commander with continuous high quality situational awareness without significant cognitive overhead. Control of the vehicle's many complex systems must also be addressed the entire Soldier Machine Interface must be optimized if we are to realize the potential performance improvements. Defence Research and Development Canada (DRDC) and General Dynamics Canada Ltd. have embarked on a joint program called Future Armoured Fighting Vehicle Systems Technology Demonstrator, to explore these issues. The project is based on man-in-the-loop experimentation using virtual reality technology on a six degree-of-freedom motion platform that simulates the motion, sights and sounds inside a future armoured vehicle. The vehicle commander is provided with a virtual reality vision system to view a simulated 360 degree multi-spectrum representation of the battlespace, thus providing enhanced situational awareness. Graphic overlays with decision aid information will be added to reduce cognitive loading. Experiments will be conducted to evaluate the effectiveness of virtual control systems. The simulations are carried out in a virtual battlefield created by linking our simulation system with other simulation centers to provide a net-centric battlespace where enemy forces can be engaged in fire fights. Survivability and lethality will be measured in successive test sequences using real armoured fighting vehicle crews to optimize overall system effectiveness.

    The management of trauma patients continues to be a major focus of resident training. The purpose of this review is to compare the mechanism and distribution of injuries in civilian and military trauma and to ascertain whether we are optimally preparing surgeons for the injuries seen on the battlefield. We performed a retrospective 5-year review of all trauma admissions to our urban trauma center (TC). We then compared this data with that recently acquired from Operation Iraqi Freedom (OIF). There were 7732 trauma patients seen during that time at our TC with 9.8 per cent sustaining gunshot wounds. Of those, 26 per cent sustained a gunshot wound to the thorax, and injuries to the abdomen and pelvis were sustained in 28.5 per cent. In total, truncal trauma accounted for 55 per cent of the injuries. Extremity injuries occurred in just 31 per cent. Data from OIF show the mechanism and distribution of injuries to be quite different. Improvised explosive devices accounted for greater than 50 per cent of the injuries in OIF. Truncal injuries accounted for just 14 per cent of the injuries seen and extremity injuries accounted for, a significant, 56 per cent of all the injuries observed. The civilian experience with gunshot wounds often focuses on truncal trauma, yet the military data show a need for knowledge of devastating injuries to the extremity. This divergent experience may be even more salient in the future as the battlefield is brought closer to home through domestic terrorism and the line is blurred between military and civilian trauma.

    Poisoning is an increasingly common social problem in Nepal. Studies on poisoning in semi urban areas of Nepal are minimal. Here we, present a prospective study of poisoning in semi urban area of capital, Kathmandu lasting for six years duration. Altogether there were 354 cases of various poisoning, admitted in Nepal Medical College Teaching Hospital from Baisakh 2062 (April 16, 2005) to Chaitra 2067 (April 15, 2011). Male: Female ratio was 135:219 (1:1.6) and Age +/- SD was age 29.3 +/- 13.8 years. Age group (20-29 years) comprised of 138 patients (38.9% followed by < 20 years age group (92, 25.9%). Brahman/ chhetri (150, 42.4%) and Mongolian (146, 41.2%) ethnic groups were the main sufferers of poisoning, followed by newars (41, 11.6%) patients. Deliberate self harm was the cause for poisoning in maximum number of patients (156, 44.1%), followed by depression (64, 18.1%) and accidental poisoning (42, 11.9%). Organophosphorus (152, 42.9%), medicines (71, 20.1%), and rodenticide poisoning (38, 10.7%) were common poisons. Metacid (Methyl parathion) (46, 15.5%) was the most popular brand of poisoning agent used in Nepal for suicidal purpose. The over all mortality rate of poisoning in general was 7.1% with organophosphorus poisoning topping the list (19, 12.5%). We also present mad honey poisonings in a small group of 9 (3.2%) patients with M:F 8:1, age 26.5 +/- 8.8 years. Due precaution should be undertaken during their management as some of them may go into cardiopulmonary arrest and should not be considered benign when more than 5 tablespoonful wild honey is consumed.

    Paracetamol poisoning is the commonest overdose seen in the UK. The management of patients with paracetamol poisoning has been little changed for the past 40 years, with a weight related dose of antidote (acetylcysteine) and treatment based on nomograms relating paracetamol concentration to time from ingestion. In 2012 the UK Commission on Human Medicines recommended a revision of the nomogram, following the death of a young woman, lowering the treatment threshold for all patients. As a result many more patients were treated. This has resulted in a large increase in admissions and in the proportion suffering adverse reactions to the antidote acetylcysteine since, interestingly, higher paracetamol concentrations inhibit anaphylactoid reactions to the antidote. New approaches to assessing the toxicity of paracetamol are now emerging using new biomarkers in blood. This article discusses new approaches to risk assessment and treatment for paracetamol overdose based on recent research in this area. PMID:26099917

    The aim of this study was to present the characteristics of medicolegal autopsies of fatal poisonings in Trabzon (Turkey), performed from 1998 to 2008, to contribute to the available data on this topic. A retrospective study of the forensic records and the toxicological data of all autopsies performed over that period revealed that 285 cases (6.34%) of the 4492 total autopsies performed were attributed to fatal poisoning. Major toxic substances were classified in five categories as follows: carbon monoxide (CO), insecticides, prescription medications, narcotic drugs, and alcohol (methyl and ethyl). CO was the most frequent cause of death (63.2%), followed by insecticides (17.2%), prescription medications and narcotic drugs (9.8%), alcohol (7.7%), and others (mushroom, rodenticide, and botulism) (2.1%). Ages of the patients ranged from 1 to 86 years (21.55 ± 36.56). PMID:21447071

    A new rapid, sensitive and reliable method was developed for the determination of phosgene in air samples using thermal desorption (TD) followed by gas chromatography-mass spectrometry (GC-MS). The method is based on a fast (10 min) active sampling of only 1 L of air onto a Tenax® GR tube doped with 0.5 mL of derivatizing mixture containing dimercaptotoluene and triethylamine in hexane solution. Validation of the TD-GC-MS method showed a low limit of detection (40 ppbv), acceptable repeatability, intermediate fidelity (relative standard deviation within 12 %) and excellent accuracy (>95%). Linearity was demonstrated for two concentration ranges (0.04 to 2.5 ppmv and 2.5 to 10 ppmv) owing to variation of derivatization recovery between low and high concentration levels. Due to its simple on-site implementation and its close similarity with recommended operating procedure (ROP) for chemical warfare agents vapour sampling, the method is particularly useful in the process of verification of the Chemical Weapons Convention.

    Animals exposed to phosgene (Psg) result in acute lung injury (ALI). We have recently reported that angiopoietin-1 (Ang1) reduces inflammation and vascular hyperpermeability in ALI animals. In this study, we examined whether the beneficial effects of adenovirus-delivered Ang1 (Ad/Ang1) on inflammatory responses in Psg-induced ALI rats are due to the suppression of the nuclear factor-kappa B (NF-κB) and p38 mitogen-activated protein kinase (MAPK) pathways, which play crucial roles in inflammatory responses in ALI. We demonstrated that Psg increased Ang2 and inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin (IL)-4 (IL-4), IL-6, IL-8, and IL-10, in the serum and bronchoalveolar lavage fluid of ALI rats, determined by ELISA. Ang1 inhibits pro-inflammatory mediators (TNF-α, IL-6 and IL-8) and has no effect on anti-inflammatory mediators (IL-4 and IL-10). Furthermore, the inhibitory action of Ang1 was mediated by the suppression of the NF-κB and p38 MAPK pathways, leading to the attenuation of inflammatory responses of ALI. Thus, Ad/Ang1 may provide a useful tool for the effective treatment in Psg-induced ALI. PMID:24517841

    A Fourier transform spectrum of phosgene (Cl2CO) has been recorded in the 22.5 μm spectral region at a resolution of 0.00102 cm-1 using a Bruker IFS125HR spectrometer coupled to synchrotron radiation leading to the observation of the ν6 vibrational bands of the two isotopologues 35Cl2CO and 35Cl37ClCO. The corresponding upper state ro-vibrational levels were fit using Watson-type Hamiltonians. In this way it was possible to reproduce the upper state ro-vibrational levels to within the experimental uncertainty i.e. ∼0.30 × 10-3 cm-1. Very accurate rotational and centrifugal distortion constants were derived from the fit together with the following band centers: ν0(ν6,35Cl2CO) = 443.172062(15) cm-1, ν0(ν6,35Cl37ClCO) = 440.534956(17) cm-1.

    This article describes the controversy between the US Fish and Wildlife Service, the National Wildlife Federation and the increased mortality of bald eagles. The eagles are being poisoned by preying on waterfowl which have ingested lead shot or have been wounded by shot and not recovered. The controversy has resulted in the establishment of new criteria for so-called non-toxic shot waterfowl hunting.

  14. Congenital PCB poisoning: a reevaluation

    A review of the literature reveals a need to clarify the pathologic physiology of congenital polychlorinated biphenyl (PCB) poisoning, which is characterized by intrauterine growth retardation, brown staining of the skin and mucous membranes as in Addison's disease, natal teeth, widely open fontanelles and sagittal suture and apparent overgrowth of the gingiva. The skull abnormalities may represent irregular calcification, with natal teeth appearing because the bone of the mandible is penetrated more easily than usual. Some fetuses were poisoned at the time the mothers ingested the oil; others were affected in the subsequent years from residual contamination in the mothers' bodies. The misadventure in Japan was repeated in Taiwan in 1979. The seven congenital cases in Taiwan reported thus far seem to differ from those in Japan. In Taiwan the noses were somewhat black, two of the infants did not have low birth weight and the osseous abnormalities of the skull and gingival hyperplasia were not observed. Systematic followup studies should be made in Taiwan of the children born within 2 years of maternal poisoning with PCBs. Special attention should be given to age at first dentition and skull-X-rays for spotty calcification, among other measures of physical, neurologic and intellectual development.

  15. Alsike clover poisoning: A review

    PubMed Central

    Nation, P. Nicholas

    1989-01-01

    Trifolium hybridum (alsike clover) has been implicated as the cause of two diseases of the horse. One of these is photosensitivity, of which alsike clover is only one of a number of presumed causal agents. The other is a fatal syndrome which is known as “alsike clover poisoning” and which is manifest by progressive loss of condition, signs of hepatic failure, and varying degrees of neurological impairment. The underlying lesion of alsike clover poisoning is fibrosis and proliferation of the biliary tree. The experimental evidence implicating alsike clover as the cause of this syndrome comes entirely from a series of feeding trials performed by Dr. Frank Schofield between 1928 and 1933. This review surveys the literature on the association of alsike clover with both photosensitivity and biliary fibrosis in horses, and summarizes the clinical and pathological features of “alsike clover poisoning”. The experimental evidence that has been used to implicate Trifolium hybridum as the cause of alsike clover poisoning is critically examined. It is concluded that the existing experimental evidence is insufficient to prove that Trifolium hybridum is the cause of alsike clover poisoning. PMID:17423321

    Unnatural deaths of married women amongst the total female deaths have been an increasing trend in Indian society during the recent past years. These unnatural deaths may be suicide, homicide or even accidents. But these suicides and homicides are currently more commonly associated with the dowry disputes. In India, dowries are a continuing series of gifts endowed before and after the marriage. When dowry expectations are not met, the young bride may be killed or compelled to commit suicide, either by burning, poisoning or by some other means. Here, in the study, the main objective is to present the different epidemiological and medicolegal aspects of poisoning deaths in the married women. In a cohort of 200 married female deaths, 35 (18%) were poisoning deaths and these were analyzed from both epidemiological and medicolegal aspects. In this series, most of the women consumed organophosphorus compound and died within 10 days. The majority of the affected wives due to dowry problems were below 35 years of age. Most incidents occurred either during morning hour or during daytime. PMID:15261005

    Prior to the 1950's, there existed no formal system for poison prevention or treatment in the US. Estimates place the number of pediatric poisoning fatalities at over 400/y at that time. After World War II, urbanization and modern technological methods brought forth over 250,000 different brand name products on the market. Health care professionals presented with cases of acute poisoning usually had little knowledge of what ingredients were contained in these new products, making it difficult to treat these patients. In the 1930's, pharmacist Louis Gdalman established a poison information service at St Luke's hospital. Because of Gdalman's training in pharmacy and chemistry, physicians throughout Chicago and the US called on him in search of assistance. In the late 1940's, Gdalman began recording information on small cards, and developed a standard data collection from. By the 1950's he had established an extensive library on the management of acute and chronic poisonings. In 1948, a national effort to reduce the number of accidents in children was started by the American Academy of Pediatrics, and a committee was formed in Chicago to address this public safety need. In November, 1953, the poison center at Presbyterian-St Luke's Hospital was formally recognized, and the poison program model spread nationwide. As the number of poison centers grew, coordination was achieved through the National Clearing House for Poison Control Centers, founded in 1957, and the American Association of Poison Control Centers, created in 1958. By 1970, the number of poison centers in the US was reported to be 597. The need for large and better centers led to regional poison control centers. Other outgrowths were the formation of the National Poison Prevention Week Council, the enactment of the Poison Prevention Packaging Act, development of "Mr. Yuk" and other symbols, and formation of the National Animal Poison Control Center. As a result, the number of children dying from accidental

    Many of the wastes from processing fissile materials contain metals which may serve as nuclear criticality poisons. It would be advantageous to the criticality evaluation of these wastes to demonstrate that the poisons remain with the fissile materials and to demonstrate an always safe poison-to-fissile ratio. The first task, demonstrating that the materials stay together, is the job of the chemist, the second, calculating an always safe ratio, is an object of this paper.

    A serious and common accident in rural Kenyan homesteads is accidental ingestion of paraffin when it has been mistaken for water and offered to a young child. Here we report the incidence, parental practices and outcome of severe paraffin poisoning, requiring admission at Kilifi District Hospital, Kenya. Over a 2-year period, 48 children (0.5% of all admissions) were admitted with kerosene poisoning, constituting 62% of all poisoning cases. All cases were accidental. Ten per cent had induced vomiting. One child (2%) died. We suggest these data support assessment followed by implementation of practical and affordable measures to prevent paraffin poisoning.

    A ground-penetrating radar survey was conducted at the Monroe Crossroads Battlefield site at Fort Bragg, North Carolina, to determine possible locations of subsurface archaeological features. An electromagnetic survey also was conducted at the site to verify and augment the ground-penetrating radar data. The surveys were conducted over a 67,200-square-foot grid with a grid point spacing of 20 feet. During the ground-penetrating radar survey, 87 subsurface anomalies were detected based on visual inspection of the field records. These anomalies were flagged in the field as they appeared on the ground-penetrating radar records and were located by a land survey. The electromagnetic survey produced two significant readings at ground-penetrating radar anomaly locations. The National Park Service excavated 44 of the 87 anomaly locations at the Civil War battlefield site. Four of these excavations produced significant archaeological features, including one at an abandoned well.

    Injuries of the musculoskeletal system are at 60% of all battlefield injures and take first place in modern military conflicts. The main antishock measures are: pain management, emergency bleeding control, bone fragment positioning and fracture fixation. Specialist of the centre of traumatology and orthopaedics of the Burdenko General Military Clinical Hospital in cooperation with specialists of department of battlefield surgery of Mandryka Clinical Research and Training Medical Centre analysed the most effective domestic and foreign external fixators and developed Rod field package (RFP). The above mentioned researched had two stages. On the first (analytical) stage specialists formulated requirements for idea rod field external fixator. On the second (experimental) stage tests with the help of plastic models of long bones were carried out. The performed analysis showed, that installation of the external fixator is easy and fast, the external fixator is light and has capabilities for 3D bone fragment positioning and fracture fixation, the external fixator is radiotransparent. Implementation of this package into the clinical practice of delivery of battlefield emergency surgical care may improve results of treatment. PMID:25051785

    Indigo, also known in Morocco as Nila, is a dye widely used in the coloring of Moroccan handicrafts. It is obtained from fermentation reactions on the leaves and branches of true indigo, Indigofera tinctoria, which is a widespread plant in tropical Africa and Asia. We report a case of fatal poisoning in a 3-year-old child after administration of indigo for therapeutic purposes. Death resulted from multiple organ failure. The toxicity of this compound is little known in the literature and deserves to be explored through toxicokinetic and toxicodynamic studies, in order to better determine the toxic constituents of the dye.

    A high school student became ill and later unconscious while working over a heating table set over three cans of burning Sterno. Measurements of 1000 to 3000 parts per million of carbon monoxide were obtained around and above the apparatus. Although the room was well ventilated there was incomplete combustion of the canned heating fuel because the apparatus was surrounded by aluminum foil, which resulted in poor oxygenation of the flame area. This case demonstrates the hazards of carbon monoxide poisoning from incompletely burned Sterno. PMID:638911

  8. Dialectical behavior therapy deployed: an aggressive alternative to traditional mental health on the noncontiguous battlefield.

    PubMed

    Parrish, Brian D

    2008-01-01

    This paper provides a description of the Witmer Wellness Center, the first successful military application of dialectical behavior therapy in a theater of war. Dialectical behavior therapy is a dynamic and provocative evidenced-based modification of cognitive behavioral treatment developed by Dr Marsha Linehan for patients with severe emotional dysregulation. One of the primary concepts of dialectical behavior therapy is that self-harming behaviors are learned, and provide evidence of maladaptive coping that is reinforced in an invalidating environment. Dialectical behavior therapy recommends a hierarchy of goals to effectively address the behaviors associated with dysregulation. Chief among these goals is reducing risk of violence to self or others. Dialectical behavior therapy is especially well-suited for the complex and dynamic environment of the noncontiguous battlefield with its chronic threat of ultraviolence, strain of nonresponse, shifting rules of engagement, and extended duration and frequency of combat deployments. The Witmer Wellness Center program uses an intensive outpatient organizational structure and minimal, but innovative, modifications to standard dialectical behavior therapy designed to meet the special requirements of Warriors in a combat zone. The Wellness Center program was designed and implemented during Operation Iraqi Freedom 07-09, at a time during the troop surge when suicide rates among US forces had reached an unprecedented level.

    Performance characteristics of the US Army DT-236 battlefield personnel dosimetry system were evaluated using the Health Physics Research Reactor at Oak Ridge National Laboratory. The DT-236 dosimeter is designed to measure total (neutron plus gamma) radiation dose using a radiophotoluminescent (RPL) detector for gamma rays and a silicon diode for fast neutrons. Areas considered in this evaluation included preirradiation dose indication; accuracy and precision of total, gamma, and neutron dose measurements; fading; angular response; temperature dependence; and relative dosimeter response in air and on various body locations. Experimental results for a variety of radiation fields and dose levels indicate that the existing system overestimates total, neutron, and gamma radiation doses in air by about 20 to 60% relative to reference values. Associated measurement precisions were about +-5% of the means for doses above approximately 0.5 Gy. Fading characteristics, angular dependence, and temperature dependence of the RPL and diode systems were consistent with results expected based on detector characteristics and previous performance studies. Recommendations to improve existing reader performance and measurement accuracy are also presented.

    Battlefield acupuncture is a unique auricular acupuncture procedure which is being used in a number of military medical facilities throughout the Department of Defense (DoD). It has been used with anecdotal published positive impact with warriors experiencing polytrauma, post-traumatic stress disorder, and traumatic brain injury. It has also been effectively used to treat warriors with muscle and back pain from carrying heavy combat equipment in austere environments. This article highlights the history within the DoD related to the need for nonpharmacologic/opioid pain management across the continuum of care from combat situations, during evacuation, and throughout recovery and rehabilitation. The article describes the history of auricular acupuncture and details implementation procedures. Training is necessary and partially funded through DoD and Veteran's Administration (VA) internal Joint Incentive Funds grants between the DoD and the VA for multidisciplinary teams as part of a larger initiative related to the recommendations from the DoD Army Surgeon General's Pain Management Task Force. Finally, Uniformed Services University of the Health Sciences School of Medicine and Graduate School of Nursing faculty members present how this interdisciplinary training is currently being integrated into both schools for physicians and advanced practice nurses at the Uniformed Services University of the Health Sciences. Current and future research challenges and progress related to the use of acupuncture are also presented. PMID:27601311

    Isolated patches of native vegetation in human-modified landscapes are important reservoirs of biological diversity because they may be the only places in which rare or native species can persist. Manassas National Battlefield Park, Virginia, is an island embedded in a matrix of intensively modified lands; it is becoming increasingly isolated due to growth of the greater Washington, D.C. area. A series of cliffs along Bull Run support an eastern white pine community disjunct from its more typical range in the Appalachian Mountains. Cliffs frequently support vegetation communities that differ from surrounding habitat. In this ecological context, the cliffs along Bull Run are islands of specialized habitat within an island of natural and semi-natural communities (the park), surrounded by a human-dominated landscape. A floral survey of these cliffs was a top priority identified by the National Park Service National Capital Region via the National Resource Preservation Program; in 2014, we completed a floral survey of 11 cliffs in the park. We recorded 282 species in 194 genera and 83 families, including 23 newly documented species for the park.

    Background Clinicians are often challenged to manage critically ill poison patients. The clinical effects encountered in poisoned patients are dependent on numerous variables, such as the dose, the length of exposure time, and the pre-existing health of the patient. The goal of this article is to introduce the basic concepts for evaluation of poisoned patients and review the appropriate management of such patients based on the currently available literature. Methods An unsystematic review of the medical literature was performed and articles pertaining to human poisoning were obtained. The literature selected was based on the preference and clinical expertise of authors. Discussion If a poisoning is recognized early and appropriate testing and supportive care is initiated rapidly, the majority of patient outcomes will be good. Judicious use of antidotes should be practiced and clinicians should clearly understand the indications and contraindications of antidotes prior to administration. PMID:19563673

    Acetonitrile (methyl cyanide) is a common industrial organic solvent but is a rare cause of poisoning. We report the first recorded UK case. Acetonitrile is slowly converted to cyanide, resulting in delayed toxicity. We describe a case of deliberate self-poisoning by a 39-year-old woman resulting in cyanide poisoning 11 hours later which was successfully treated by repeated boluses of sodium nitrite and thiosulphate. The half-life of conversion of acetonitrile was 40 hours and harmful blood cyanide levels persisted for over 24 hours after ingestion. Departments treating or advising in cases of poisoning need to be aware of the delayed toxicity of acetonitrile. Monitoring in an intensive care unit of cases of acetonitrile poisoning should continue for 24-48 hours. PMID:9196706

The relevant cases reported to the Swiss Toxicological Information Center (STIC) were compared with those from previously examined periods. Human medicines not approved for animals and pesticides represented the most common causes of poisoning in dogs. Novel cases occurred as a consequence of the exposure of dogs to ricinus fertilizers, grape residues from wineries, pepper lachrymatory spray and dry bouillon. Cats are still freequently poisoned by pyrethroid drugs that should be administered only to dogs. Agrochmical products are the main source of toxicities in farm animals. Most poisonings in horses and exotic animals took place due to toxic plants. In addition, two tigers died of a secondary poisoning after ingestion of meat from euthanized calves. PMID:26753326

Suspected occurrences are infrequent and seasonal. Most cases of ciguatera fish poisoning are undocumented that when cases do occur they depend largely on traditional-knowledge and anecdotal information. Areas suspected to have ciguatoxic poisoning problem in the Solomon Islands includes Santa Cruz, Rennell and Bellona, Indispensable reefs, Ontong Java and Wagina island. Fish species considered ciguatoxic includes red emperor, red snapper, roundfaced batfish, barracuda and blue lined sea-bream.

    An unusual manner of carbon monoxide poisoning claimed the lives of two adults in two separate incidents. In the first case, a young man was four wheeling in a swampy area when his jeep became stuck in the mud as he continued to floor the accelerator. Carbon monoxide fumes entered the vehicle through the rusted floorboards, killing the driver. In the second case, two teens were skinny dipping behind a motor boat when they became affected by the boat exhaust. One of the youths was overcome and submerged into the lake. Both incidents were initially attributed to incorrect causes--a car accident and a drowning--because of the false notion that carbon monoxide is not a hazard in a ventilated area. The carboxyhemoglobin levels in these victims were 78 and 62% respectively. It was only through laboratory testing that carbon monoxide poisoning was identified as the cause of their demise. Physicians as well as the public need to be aware of the potential for this life threatening hazard to occur so that there can be proper emergency treatment and the prevention of fatalities.

    Information on childhood poisonings in Cyprus is limited. Our objective was to examine the epidemiology of poisonings among children in Cyprus. All children up to 15 years of age admitted for poisoning to the Archbishop Makarios Hospital in Nicosia, Cyprus between 2005 and 2008 were included in our study. All hospital poisoning records were reviewed. A total of 257 children were admitted for poisoning. The mean age of children was 3.1 years, of which 83.7% were below the age of 5 years old, while 53% were boys. The poisoning hospitalizations accounted for about 3% of all admissions to the pediatric department during the study period (4 years). The annual cumulative incidence of childhood poisoning hospitalizations was 116 per 100,000 children. Medications accounted for 46.1% of all poisonings, the most frequent cause being paracetamol (9.8%), cardiovascular medications (5.3%), antitussive medications (4.5%), and other painkillers (4.1%). Another 37.6% of hospitalizations involved household products such as household cleaning products (11.8%), petroleum products (11.0%), and rodenticides (5.7%). Among children who ingested petroleum distillates, 55.6% developed clinical symptomatology. The vast majority of cases were accidental (93.8%). Suicidal cases involved children 8-14 years old, mainly girls, and the most frequent poisoning ingested was paracetamol (46.7%). Poisoning hospitalizations represent an important cause of morbidity among children in Cyprus. Preventive strategies should include the education of caregivers on the handling of medications and household products as well as legislation requiring child-resistant packaging for all medications and household products including petroleum distillates.

    Red-winged blackbirds (Agelaius phoeniceus), brown-headed cowbirds (Molothrus ater), common grackles (Quiscalus quiscula), mallards (Anas platyrhynchos), northern bobwhites (Colinus virginianus), and eastern screech-owls (Otus asio) were poisoned with a concentration of lead (Pb) acetate in the diet which was increased by 60% each week until half of the birds in each treatment group died; surviving birds and all control birds except screech-owls were then killed by euthanasia. An additional group of mallards was poisoned with Pb shot. The gizzards of mallards poisoned either way usually were stained with bile; some of these birds also had proventricular impaction. Most poisoned birds of the other species were emaciated but lacked other gross lesions caused by Pb poisoning. In birds other than mallards, Pb poisoning could not be diagnosed without histological or hematological examinations or analysis of tissues. Poisoned birds of all six species could be reliably separated from control birds by an increase in the protoporphyrin concentrations in the blood and by a decrease in the activity of delta-aminoievulinic acid dehydratase (ALAD) in red blood cells. Hepatic iron (Fe) concentrations varied so much among individual birds that even though median hepatic Fe concentrations increased in poisoned birds, hepatic Fe concentrations were not useful in identifying poisoned birds. Renal intranuclear inclusion bodies occurred in 83% of all birds dying from Pb poisoning. Nephrosis, myocardial necrosis, and arterial fibrinoid necrosis were occasionally present. Median hepatic Pb concentrations varied from 20 ppm (wet wt) in male red-winged blackbirds to III ppm in female northern bobwhites.

    Red-winged blackbirds (Agelaius phoeniceus), brown-headed cowbirds (Molothrus ater), common grackles (Quiscalus quiscula), mallards (Anas platyrhynchos), northern bobwhites (Colinus virginianus), and eastern screech-owls (Otus asio) were poisoned with a concentration of lead (Pb) acetate in the diet which was increased by 60% each week until half of the birds in each treatment group died; surviving birds and all control birds except screech-owis were then killed by euthanasia. An additional group of mallards was poisoned with Pb shot. The gizzards of mallards poisoned either way usually were stained with bile; some of these birds also had proventricular impaction. Most poisoned birds of the other species were emaciated but lacked other gross lesions caused by Pb poisoning. In birds other than mallards, Pb poisoning could not be diagnosed without histological or hematological examinations or analysis of tissues. Poisoned birds of all six species could be reliably separated from control birds by an increase in the protoporphyrin concentrations in the blood and by a decrease in the activity of delta-aminolevulinic acid dehydratase (ALAD) in red blood cells. Hepatic iron (Fe) concentrations varied so much among individual birds that even though median hepatic Fe concentrations increased in poisoned birds, hepatic Fe concentrations were not useful in identifying poisoned birds. Renal intranuclear inclusion bodies occurred in 83% of all birds dying from Pb poisoning. Nephrosis, myocardial necrosis, and arterial fibrinoid necrosis were occasionally present. Median hepatic Pb concentrations varied from 20 ppm (wet wt) in male red-winged blackbirds to 111 ppm in female northern bobwhites. Median renal Pb concentrations varied from 22 ppm in redwinged blackbirds to 190 ppm in female northern bobwhites. Hepatic and renal Pb concentrations varied substantially among birds within each species. Median hepatic and renal Pb concentrations of birds that died were not statistically

    The stop-signal paradigm has been widely adopted as a way to parametrically quantify the response inhibition process. To evaluate inhibitory function in realistic environmental settings, the current study compared stop-signal responses in two different scenarios: one uses simple visual symbols as go and stop signals, and the other translates the typical design into a battlefield scenario (BFS) where a sniper-scope view was the background, a terrorist image was the go signal, a hostage image was the stop signal, and the task instructions were to shoot at terrorists only when hostages were not present but to refrain from shooting if hostages appeared. The BFS created a threatening environment and allowed the evaluation of how participants’ inhibitory control manifest in this realistic stop-signal task. In order to investigate the participants’ brain activities with both high spatial and temporal resolution, simultaneous functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) recordings were acquired. The results demonstrated that both scenarios induced increased activity in the right inferior frontal gyrus (rIFG) and presupplementary motor area (preSMA), which have been linked to response inhibition. Notably, in right temporoparietal junction (rTPJ) we found both higher blood-oxygen-level dependent (BOLD) activation and synchronization of theta-alpha activities (4–12 Hz) in the BFS than in the traditional scenario after the stop signal. The higher activation of rTPJ in the BFS may be related to morality judgments or attentional reorienting. These results provided new insights into the complex brain networks involved in inhibitory control within naturalistic environments. PMID:27199708

    2010-01-01

    The QuickStrike ASOC (Air Support Operations Center) Battlefield Simulation fills a crucial gap in USAF and United Kingdom Close Air Support (CAS) and airspace manager training. The system now provides six squadrons with the capability to conduct total-mission training events whenever the personnel and time are available. When the 111th ASOC returned from their first deployment to Afghanistan they realized the training available prior to deployment was inadequate. They sought an organic training capability focused on the ASOC mission that was low cost, simple to use, adaptable, and available now. Using a commercial off-the-shelf simulation, they developed a complete training system by adapting the simulation to their training needs. Through more than two years of spiral development, incorporating lessons learned, the system has matured, and can now realistically replicate the Tactical Operations Center (TOC) in Kabul, Afghanistan, the TOC supporting the mission in Iraq, or can expand to support a major conflict scenario. The training system provides a collaborative workspace for the training audience and exercise control group via integrated software and workstations that can easily adapt to new mission reqUirements and TOC configurations. The system continues to mature. Based on inputs from the war fighter, new capabilities have been incorporated to add realism and simplify the scenario development process. The QuickStrike simulation can now import TBMCS Air Tasking Order air mission data and can provide air and ground tracks to a common operating picture; presented through either C2PC or JADOCS. This oranic capability to practice team processes and tasks and to conduct mission rehearsals proved its value in the 111 h ASOS's next deployment. The ease of scenario development and the simple to learn and intuitive gamelike interface enables the squadrons to develop and share scenarios incorporating lessons learned from every deployment. These war fighters have now

    Objective: Methadone poisoning can occur accidentally or intentionally for suicide or homicide purposes. The aim of this study was to evaluate the epidemiological and clinical manifestations of Methadone poisoning. Methods: A descriptive analytical study was performed from 2010 to 2012 in the poisoning emergency and clinical toxicology departments of Noor hospital affiliated with Isfahan University of Medical Sciences (Isfahan, Iran). All patients with Methadone poisoning within this period of time were investigated. Different variables were recorded in a checklist. Findings: A total of 385 patients were studied. About 85.7% had ingested only Methadone and 14.3% had ingested other medications with Methadone. Mean ± standard deviation of the age was 32.1 ± 15 years (range: 1-90). Most of the patients were male (76.4%). Nearly 40% of the patients were narcotic addicts, 25.5% were addicts under surveillance of Methadone maintenance therapy centers and 34.5% were non-addicts. Intentional poisoning was observed in most of the patients (57.7%). Most of the patients had a low level of consciousness on admission (58.2%). Respiratory depression and hypotension was observed in 35.6% and 12.7% of the cases as the most common symptoms. Regarding vital signs, there was a significant difference in respiratory rate on admission among different evaluated groups (P = 0.02). Length of hospital stay was 18.79 ± 0.72 h (range: 4-240 h, median: 15 h). About 57 patients (25.8%) from the intentionally poisoned patients and 19 patients (12.3%) from the unintentionally poisoned patients had a history of psychiatric disorder (P = 0.001). Most of the patients survived without complications. Conclusion: Addiction, age, gender, attempt to suicide and a history of psychiatric disorder were of the most important factors effective in Methadone poisoning, which should be considered in the public training and prevention of poisoning.

    A retrospective study was carried out by reviewing all suspected cases of domestic animal poisoning attributed to pesticides, reported to the Milan Poison Control Centre (MPCC) between January 2011 and December 2013. During this period, pesticides were found to be responsible for 37.3% of all suspected poisoning enquiries received (815). The most commonly species involved was the dog (71.1% of calls) followed by the cat (15.8%), while a limited number of cases involved horses, goats and sheep. Most cases of exposure (47.1%) resulted in mild to moderate clinical signs. The outcome was reported in 59.9% of these cases, with death occurring in 10.4% of them. Insecticides (40.8%) proved to be the most common group of pesticides involved and exposure to pyrethrins-pyrethroids accounted for the majority of calls. According to the MPCC data, there has been a decrease in the number of suspected poisonings cases attributed to pesticides that have been banned by the EU, including aldicarb, carbofuran, endosulfan and paraquat. In contrast, there has been an increase of suspected poisoning cases attributed to the neonicotinoids, imidacloprid and acetamiprid, probably due to their widespread use in recent years. Cases of suspected poisoning that involved exposure to rodenticides accounted for 27.6% of calls received by the MPCC and anticoagulant rodenticides were the primary cause of calls, with many cases involving brodifacoum and bromadiolone. Herbicides were involved in 14.2% of calls related to pesticides and glyphosate was the main culprit in cases involving dogs, cats, horses, goats and sheep. As far as exposure to molluscicides (11.5%) and fungicides (5.9%), most of the cases involved dogs and the suspected poisoning agents were metaldehyde and copper compounds respectively. The data collected are useful in determining trends in poisoning episodes and identifying newly emerging toxicants, thus demonstrating the prevalence of pesticides as causative agents in animal

    The threat of civilian and military casualties from nerve agent exposure has become a greater concern over the past decade. After rapidly assessing that a nerve agent attack has occurred, emphasis must be placed on decontamination and protection of both rescuers and medical personnel from exposure. The medical system can become rapidly overwhelmed and strong emotional reactions can confuse the clinical picture. Initially, care should first be focused on supportive care, with emphasis toward aggressive airway maintenance and decontamination. Atropine should be titrated, with the goal of therapy being drying of secretions and the resolution of bronchoconstriction and bradycardia. Early administration of pralidoxime chloride maximizes antidotal efficacy. Benzodiazepines, in addition to atropine, should be administered if seizures develop. Early, aggressive medical therapy is the key to prevention of the morbidity and mortality associated with nerve agent poisoning. PMID:9330846

    Sri Lanka is a developing Asian country with high suicide rate due to self poisoning, related to a high fatality rate. A study of motivational aspects of self poisoning in 97 consecutive patients showed that there is no greater intention of suicide in them than those from the developed countries. Interpersonal disputes involving domestic problems and love affairs are the main precipitating causes. Improving family relations may help in the prevention of self-poisoning. However the impulsive nature of the act might prove prevention a difficult task. PMID:2767925

    Allergic contact dermatitis caused by the Toxicodendron (formerly Rhus) species-poison ivy, poison oak, and poison sumac-affects millions of North Americans every year. In certain outdoor occupations, for example, agriculture and forestry, as well as among many outdoor enthusiasts, Toxicodendron dermatitis presents a significant hazard. This review considers the epidemiology, identification, immunochemistry, pathophysiology, clinical features, treatment, and prevention of this common dermatologic problem. Recent research in prevention is emphasized, and resources to help in the identification of plants are provided in the bibliography. The literature was searched using a MEDLINE query for "Toxicodendron dermatitis", and the identified article bibliographies were searched as well. PMID:16805148

    Many of the storage tanks with waste from processing fissile materials contain, along with the fissile material, metals which may serve as nuclear criticality poisons. It would be advantageous to the criticality evaluation of these wastes if it can be demonstrated that the poisons remain with the fissile materials and if an always safe poison-to-fissile ratio can be established. The first task, demonstrating that the materials stay together, is the job of the chemist, the second, demonstrating an always safe ratio, is the job of the physicist. The latter task is the object of this paper

    Lead is a relatively ubiquitous heavy metal with particular features such as resistance to corrosion, high malleability and wide variety of industrial applications. In medicine, however, it is considered as a slow-acting toxic substance affecting multiple body systems, specifically functioning as a potent neurotoxin in the central nervous system. Lead poisoning may be acute or chronic and can be due to occupational or environmental exposures. The history of lead poisoning dates back to ancient times. The present paper briefly describes the worldwide historical accounts of lead poisoning with a special focus on Iran. PMID:23022790

    Because lead crosses the placenta throughout pregnancy, the fetus is at risk for lead poisoning. A full term, asymptomatic child was born with congenital lead poisoning secondary to maternal pica. Radiographic findings of a dense cranial vault, lead lines, and delayed skeletal and deciduous dental development were noted at birth. After chelation therapy, when the patient was seven months old, radiographs revealed normal skeletal maturation. Tooth eruption did not occur until 15 months of age. Newborn infants with these radiographic findings should be screened for subclinical, congenital lead poisoning.

    BACKGROUND Carbon monoxide (CO) poisoning is commonly seen during the winter season in Turkey due to use of charcoal stoves and water heaters, but narghile smoking is a rare cause of CO poisoning. CASE REPORT In this paper, we report a CO poisoning case caused by narghile smoking. The patient was admitted to the ED with nausea, dizziness, vertigo, and syncope. CONCLUSIONS The diagnosis of CO poisoning depends on suspicious anamnesis. The major treatment of CO poisoning is oxygen supply. PMID:27618983

    Raman spectra of ammonia (NH3), chlorine (Cl2), hydrogen sulfide (H2S), phosgene (COCl2), and sulfur dioxide (SO2) toxic gases have been measured in the fingerprint region 400-1400 cm-1. A relatively compact (<2'x2'x2'), sensitive, 532 nm 10 W CW Raman system with double-pass laser and double-sided collection was used for these measurements. Two Raman modes are observed at 934 and 967 cm-1 in NH3. Three Raman modes are observed in Cl2 at 554, 547, and 539 cm-1, which are due to the 35/35 35/37, and 37/37 Cl isotopes, respectively. Raman modes are observed at 870, 570, and 1151 cm-1 in H2S, COCl2, and SO2, respectively. Values of 3.68 ± 0.26x10-32 cm2/sr (3.68 ± 0.26x10-36 m2/sr), 1.37 ± 0.10x10-30 cm2/sr (1.37 ± 0.10x10-34 m2/sr), 3.25 ± 0.23x10-31 cm2/sr (3.25 ± 0.23x10-35 m2/sr), 1.63 ± 0.14x10-30 cm2/sr (1.63 ± 0.14x10-34 m2/sr), and 3.08 ± 0.22x10-30 cm2/sr (and 3.08 ± 0.22x10-34 m2/sr) were determined for the differential Raman cross section of the 967 cm-1 mode of NH3, sum of the 554, 547, and 539 cm-1 modes of Cl2, 870 cm-1 mode of H2S, 570 cm-1 mode of COCl2, and 1151 cm-1 mode of SO2, respectively, using the differential Raman cross section of 3.56 ± 0.14x10-31 cm2/sr (3.56 ± 0.14x10-35 m2/sr) for the 1285 cm-1 mode of CO2 as the reference.

    Techniques were developed to construct a set of basic poison depletion curves which deplete in a monotonical manner. These curves were combined to match a required optimized depletion profile by utilizing either linear or non-linear programming methods. Three computer codes, LEOPARD, XSDRN, and EXTERMINATOR-2 were used in the analyses. A depletion routine was developed and incorporated into the XSDRN code to allow the depletion of fuel, fission products, and burnable poisons. The Three Mile Island Unit-1 reactor core was used in this work as a typical PWR core. Two fundamental burnable poison rod designs were studied. They are a solid cylindrical poison rod and an annular cylindrical poison rod with water filling the central region.These two designs have either a uniform mixture of burnable poisons or lumped spheroids of burnable poisons in the poison region. Boron and gadolinium are the two burnable poisons which were investigated in this project. Thermal self-shielding factor calculations for solid and annular poison rods were conducted. Also expressions for overall thermal self-shielding factors for one or more than one size group of poison spheroids inside solid and annular poison rods were derived and studied. Poison spheroids deplete at a slower rate than the poison mixture because each spheroid exhibits some self-shielding effects of its own. The larger the spheroid, the higher the self-shielding effects due to the increase in poison concentration.

    Abstract Question A 4-year-old girl was brought into the emergency department vomiting after having had ingested a laundry detergent capsule (LDC) from under the sink at her house. What is the risk of LDC poisoning? What can be done to treat these children? Answer Laundry detergent capsules are relatively new to supermarket shelves in North America, and there has been an emergence of case reports in the literature describing LDC poisoning, which is worse than poisoning from other laundry detergents. Very little is known about the mechanisms causing these severe reactions, which include airway compromise and esophageal perforation, but the attractive appearance of these capsules and easy access at home has governments and health officials concerned about an increase in poisoning. No residual problems have been associated with these cases to date; however, further research is needed to assess long-term effects. PMID:24336541

    The diagnosis of mushroom poisoning is based on three principles: the description of the mushroom, the toxicological analysis of the mushroom and, most important, the mushroom syndrome. Mushroom poisoning can be classified according to the lag time between the meal and the onset of symptoms. In this paper we will discuss mushroom poisoning with short and intermediate lag time. With short lag time and a predominance of CNS signs and symptoms the diagnosis is either fly-agaric, pantherina or psilocybin syndrome. Parasympathomimetic signs and symptoms indicate the muscarine syndrome. If--with a lag period of up to four hours--vomiting and diarrhea are predominant, we will find a poisoning with one of the many mushrooms which lead to gastroenteritis. Gastroenteritis combined with hemolysis points to a paxillus syndrome. PMID:3586830

    An infant of 9 months was admitted to hospital in comatose condition; cyanide poisoning was suspected. This poisoning was caused by the desorption of hydrocyanic acid from building materials after the house had been fumigated with hydrocyanic acid under strict supervision and observed safety measures. Administration of 4-dimethyl-aminophenol, a methaemoglobin inducer, and sodium thiosulphate together with supportive measures, led to complete recovery of the infant, although the general hypotony persisted for a few weeks.

    Findings from natural cases and experiments with cattle emphasise that flowering plants are the most important form of Bryophyllum (Kalanchoe) spp in poisonings in Australia. The main life-threatening lesion is myocardial. The effects on the alimentary tract are less important than was believed previously. B. tubiflorum, B. daigremontianum x B. tubiflorum, B. pinnatum and B. proliferum caused 41 recorded poisoning incidents affecting 379 cattle in Queensland between 1960 and 1984. Poisoning occurred between May and October--the flowering season of these plants. Experimental B. tubiflorum poisoning and natural poisonings produced anorexia, depression, ruminal atony, diarrhoea, heart rate and rhythm abnormalities, dyspnoea and death. Increased plasma concentrations of urea, creatinine and glucose and decreased chloride were measured experimentally. Both natural and experimental cases had myocardial degeneration and necrosis with haemorrhages of the heart and alimentary tract. Cattle with severe dyspnoea had atelectasis and emphysema of the lungs. Some cattle had mild nephrosis. The median lethal doses of B. tubiflorum flowers, roots and leaf plus stem were 0.7, 2.3 and 5.0 g dry matter/kg liveweight respectively (7, 7 and 40 g wet weight/kg). Bufadienolides have been isolated recently from B. tubiflorum flowers and the syndrome is consistent with cardiac glycoside poisoning. PMID:3778371

  3. Aluminum phosphide poisoning: an unsolved riddle.

    Aluminum phosphide (ALP), a widely used insecticide and rodenticide, is also infamous for the mortality and morbidity it causes in ALP-poisoned individuals. The toxicity of metal phosphides is due to phosphine liberated when ingested phosphides come into contact with gut fluids. ALP poisoning is lethal, having a mortality rate in excess of 70%. Circulatory failure and severe hypotension are common features of ALP poisoning and frequent cause of death. Severe poisoning also has the potential to induce multi-organ failure. The exact site or mechanism of its action has not been proved in humans. Rather than targeting a single organ to cause gross damage, ALP seems to work at the cellular level, resulting in widespread damage leading to multiorgan dysfunction (MOD) and death. There has been proof in vitro that phosphine inhibits cytochrome c oxidase. However, it is unlikely that this interaction is the primary cause of its toxicity. Mitochondria could be the possible site of maximum damage in ALP poisoning, resulting in low ATP production followed by metabolic shutdown and MOD; also, owing to impairment in electron flow, there could be free radical generation and damage, again producing MOD. Evidence of reactive oxygen species-induced toxicity owing to ALP has been observed in insects and rats. A similar mechanism could also play a role in humans and contribute to the missing link in the pathogenesis of ALP toxicity. There is no specific antidote for ALP poisoning and supportive measures are all that are currently available. PMID:21607993

  4. Acute Plant Poisoning and Antitoxin Antibodies

    Plant poisoning is normally a problem of young children who unintentionally ingest small quantities of toxic plants with little resulting morbidity and few deaths. In some regions of the world, however, plants are important clinical problems causing much morbidity and mortality. While deaths do occur after unintentional poisoning with plants such as Atractylis gummifera (bird-lime or blue thistle) and Blighia sapida (ackee tree), the majority of deaths globally occur following intentional self-poisoning with plants such as Thevetia peruviana (yellow oleander) and Cerbera manghas (pink-eyed cerbera or sea mango). Antitoxins developed against colchicine and cardiac glycosides would be useful for plant poisonings - anti-digoxin Fab fragments have been shown to be highly effective in T. peruviana poisoning. Unfortunately, their great cost limits their use in the developing world where they would make a major difference in patient management. Therapy for some other plant poisonings might also benefit from the development of antitoxins. However, until issues of cost and supply are worked out, plant anti-toxins are going to remain a dream in many of the areas where they are now urgently required. PMID:12807314

    Plant poisoning is not uncommon in Thailand. The objective of this study was to determine the incidence, type, clinical manifestations, severity and outcomes of plant poisoned patients in Thailand over a 10-year period. We retrospectively reviewed data from the Ramathibodi Poison Center Toxic Exposure Surveillance System for 2001-2010. A total of 2,901 poisonous plant exposure cases were identified, comprising 3.1% of the 92,392 poison cases recorded during the study period. This was the fifth most common type of poisoning recorded. Children aged < 13 years comprised the largest percent (69.8%) of the cases. The major type of exposure was unintentional ingestion. Ninety-nine types of poisonous plants were recorded as the causative agents among 99.1%of the cases. Gastrointestinal symptoms were reported in 72.0% of cases with Jatropha curcas (physic nut) comprising 54.1% of these. Most patients had only minor signs and symptoms. The mortality rate among the total plant poisoning cases was 0.9%, with 26 deaths. Thirteen deaths occurred in children aged < 13 years. The greatest number of fatalities were due to ingestion of Manihot esculenta (cassava), primarily due to multi-system organ failure. Children aged < 13 years are at the greatest risk for plant poisoning in Thailand; mostly unintentional. Most cases were minor and the mortality rate was low. Jatropha curcas was the most common cause of poisoning and Manihot esculenta was the most common cause of death. Public education is important to minimize these poisonings. PMID:26867365

    Urine specimens from patients diagnosed with neurotoxic shellfish poisoning (NSP) were examined for biomarkers of brevetoxin intoxication. Brevetoxins were concentrated from urine by using solid-phase extraction (SPE), and analyzed by enzyme-linked immunosorbent assay (ELISA) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Urine extracts were fractionated by LC, and fractions analyzed for brevetoxins by ELISA. In subsequent LC-MS/MS analyses, several brevetoxin metabolites of B-type backbone were identified, with elution profiles consistent with those of ELISA. The more abundant brevetoxin metabolites in urine were characterized structurally by LC-MS/MS. With the exception of BTX-3, brevetoxin metabolites in urine differed from those found in shellfish and in shellfish meal remnants. Proposed structures of these major urinary metabolites are methylsulfoxy BTX-3, 27-epoxy BTX-3, and reduced BTX-B5. BTX-3 was found in all specimens examined. BTX-3 concentrations in urine, as determined by LC-MS/MS, correlated well with composite toxin measurements by ELISA (r(2)=0.96). BTX-3 is a useful biomarker for confirmation of clinical diagnosis of NSP. PMID:18582487

    Four cases, including three adults and one child, suffering from acute poisoning with Tricholoma equestre were described. The patients had eaten from 100 to 400 grams of the mushroom within a few consecutive meals. After consuming about 1000 grams of Tricholoma equestre for 3-4 days, the subjects developed fatigue, muscle weakness, myalgia, and in two cases acute respiratory failure with the need of respiratorotherapy. Maximal serum CK was 48136 U/L in the adults and 306 U/L in children. Maximal serum levels of AST and ALT were 802 U/L and 446 U/L in adults and 39 U/L, and 56 U/L in a child. All routine biochemical tests were within normal range. No other causes of rhabdomyolysis such as parasitic or viral infections, immune diseases, trauma or exposure to medications were found. Patient, aged 72 yrs., who developed acute respiratory failure, died in the second day of hospitalization. In other patients all the above mentioned symptoms and biochemical abnormalities disappeared from 2 to 3 weeks of hospitalization. Physicians should be aware of the possibility of appearance of rhabdo-myolysis after repeated consumption of large quantities of Tricholoma equestre. PMID:19788144

    Accidental childhood poisonings are a major public health concern despite many efforts to alleviate this problem. While the rate of pediatric fatalities due to poisonings have decreased over the last two decades, poison control centers around the US have collectively fielded over one million calls with regard to toxic exposures in the preschool age group. According to the American Association of Poison Control Centers nearly half of all human exposures reported last year involved children under six. By focusing poison prevention efforts on the preschooler, we can attempt to decrease morbidity and mortality in the most vulnerable age group affected. Although the subject is still prevalent, current discussion on this topic is limited. Newer literature discusses past initiatives such as child resistant packaging and sticker deterrent programs and addresses their efficacy. This article revisits older mechanisms of prevention as well as the science behind the human motivation to change one's own practice and behavior. PMID:25458111

    2014-12-01

    An increasing number of drugs of abuse are sold word wide over the internet. Names like "legal highs", "herbal highs" etc. give the impression that these are safe products, although the risk of fatal reactions might be substantial. Leaves from the plant Mitragyna speciosa, contain active compounds like mitragynine and 7-hydroxymitragynine. It has been reported that the potency of 7-hydroxymitragynine at the μ-opioid receptor is 30 times higher than that of mitragynine and 17 times higher than that of morphine. Case reports regarding poisoning with Kratom are reported, but the toxic or lethal ranges for the concentrations of the active substances have not been established, and concentrations of 7-hydroxymitragynine have not been reported previously. We present a case report where a middle aged man was found dead at home. The deceased had a history of drug abuse and mental illness for several years. At autopsy, there were no significant pathological findings. Post-mortem analysis of peripheral blood revealed: zopiclone 0.043mg/L, citalopram 0.36mg/L and lamotrigine 5.4mg/L, i.e. concentrations regularly seen after therapeutic ingestion of these drugs. Additionally mitragynine 1.06mg/L and 7-hydroxymitragynine 0.15mg/L were detected in blood and both also in urine. The high concentrations of mitragynine and 7-hydroxymitragynine indicate that the cause of death is intoxication by these substances; and the circumstances point toward the manner of death being accidental. We recommend that both mitragynine and 7-hydroxymitragynine are analyzed for in cases with suspected Kratom intoxication. PMID:25453780

    A 31-year-old man with a history of alcohol abuse presented to the accident and emergency department complaining of blurred vision. 4 h previously he had drunk 300 mL de-icer fluid. Electrolytes, urea, creatinine, glucose, and blood-gas analysis were normal. Measured osmolality, however, was 368 mosmol/kg with a calculated osmolality of 300 mosmol/kg, which indicated a greatly increased osmolar gap. He was therefore given 150 mL whisky and admitted. Methanol was later reported as 200 mg/dL. Ethylene glycol was not detected, but another glycol, propylene glycol, was present at 47 mg/dL. 10 h after ingestion an intravenous infusion of ethanol was started and he was hemodialysed for 7 h. After dialysis he was given a further 100 mL whisky and the rate of ethanol infusion was reduced to 11 g per h. Methanol and ethanol were measured twice daily until methanol was under 10/mg/dL: The recommendation is that blood ethanol be maintained between 100 and 200 mg/dL during treatment of methanol poisoning. This concentration was not achieved, presumably because of the high rate of ethanol metabolism often found in alcoholics. Antifreeze solutions commonly contain methanol and ethylene glycol. Sometimes propylene glycol is substituted because it has properties similar to those of ethylene glycol but is less toxic. The authors postulate that propylene glycol inhibited the metabolism of methanol in the patient, thus sparing him from the toxic effects of methanol.

  12. Nicotine replacement products: poisoning in children.

    PubMed

    2014-05-01

    Nicotine is widely used in smoking cessation aids. They are marketed in many forms, including: chewing gum, sublingual tablets, lozenges, transdermal patches, cartridges for oral inhalation, and mouth spray. French poison control and toxico-vigilance centres identified 318 cases of exposure to nicotine replacement products in children under the age of 10 years between 2000 and 2010. The exposure provoked symptoms in 62 of these children, about two-thirds of whom were under the age of 4 years. A U.S. analysis identified 1768 cases of poisoning in children under the age of 6 years involving smokeless tobacco products, reported between 2006 and 2008.84% of these cases occurred in children under the age of 3 years. The first signs of nicotine poisoning are gastrointestinal (vomiting, diarrhoea), cardiovascular (tachycardia, hypertension) and neuropsychological (tremor of the extremities). With higher doses, these effects are rapidly followed by loss of consciousness, convulsions or respiratory failure. In children, poisoning can occur after ingestion of 1 mg of nicotine per kilogram of body weight. A dose of this magnitude is sometimes fatal in adults. Most cases of poisoning involving transdermal patches occur when a child finds an unused patch, or a used patch that an adult has discarded in a bin without taking proper precautions. Sometimes they involve patches that have become detached from an adult's skin. In practice, it is important to warn adults using smoking cessation aids containing nicotine that these products are dangerous PMID:24926513

    2016-02-01

    Histamine fish poisoning, also known as scombroid poisoning, is the most common cause of ichythyotoxicosis worldwide and results from the ingestion of histamine-contaminated fish in the Scombroidae and Scomberesocidae families, including mackerel, bonito, albacore, and skipjack. This disease was first described in 1799 in Britain and re-emerged in the medical literature in the 1950s when outbreaks were reported in Japan. The symptoms associated with histamine fish poisoning are similar to that of an allergic reaction. In fact, such histamine-induced reactions are often misdiagnosed as IgE-mediated fish allergy. Indeed, histamine fish poisoning is still an underrecognized disease. In this review, we discuss the epidemiology, pathophysiology, evaluation, and treatment of scombroid disease. Because more than 80% of fish consumed in the USA is now imported from other countries, the disease is intimately linked with the global fish trade (National Marine Fisheries Service, 2012). Preventing future scombroid outbreaks will require that fishermen, public health officials, restaurant workers, and medical professionals work together to devise international safety standards and increase awareness of the disease. The implications of scombroid poisoning go far beyond that of fish and have broader implications for the important issues of food safety. PMID:25876709

    There are over 2 million human exposure cases reported to United States poison centers annually. Much of the data involves exposure through ingestion, dermal contact, inhalation, ocular, or parenteral routes. There is limited data characterizing exposure via atypical routes. We conducted a retrospective review of the California Poison Control System Database for a 24-month period from January 2012 to December 2013 for poison exposure that occurred through the otic, vaginal, or rectal route. There were a total of 634 cases involving single-route and single-substance atypical poison exposure. There were 287 (45%) cases of otic exposure, 190 (30.0%) cases of vaginal exposure, and 157 (25%) cases of rectal exposure. Five hundred forty (85%) of the cases were unintentional. Gasoline exposure through the otic route occurred in 83 (13.1%) cases, followed by hydrogen peroxide (4.7%), acetaminophen (3.8%), and miconazole (2.7%). Adverse effects occurred in 336 (53%) cases. No deaths were reported. The most common treatment was observation only, occurring in 396 (62.4%) cases. The majority of the cases did not warrant hospital evaluation (73.5%). This is the first retrospective characterization study of atypical routes of poison exposure. These results may provide education to providers and the public regarding risks of exposure to substances through atypical routes. PMID:26250476

    Four waterfowl were collected in the TriState Mining District (Oklahoma, Kansas and Missouri, USA), an area known to be contaminated with lead, cadmium and zinc (Zn). They were part of a larger group of 20 waterfowl collected to determine the exposure of birds to metal contamination at the site. The four waterfowl (three Branta canadensis, one Anas platyrhynchos) had mild to severe degenerative abnormalities of the exocrine pancreas, as well as tissue (pancreas, liver) concentrations of Zn that were considered toxic. The mildest condition was characterized by generalized atrophy of exocrine cells that exhibited cytoplasmic vacuoles and a relative lack of zymogen. The most severe condition was characterized by acini with distended lumens and hyperplastic exocrine tissue that completely lacked zymogen; these acini were widely separated by immature fibrous tissue. Because the lesions were nearly identical to the lesions reported in chickens and captive waterfowl that had been poisoned with ingested Zn, and because the concentrations of Zn in the pancreas and liver of the four birds were consistent with the concentrations measured in Zn-poisoned birds, we concluded that these waterfowl were poisoned by Zn. This may be the first reported case of zinc poisoning in free-ranging wild birds poisoned by environmental Zn.

  17. Possible role for anisodamine in organophosphate poisoning.

    2016-06-01

    In cases of organophosphate poisoning, patients are treated with a combination of antidotes. In addition to these poison-directed antidotes, patients may require extra oxygen and artificial ventilation; other modalities may also be needed due to the wide range of toxic effects. Anisodamine is a belladonna alkaloid, and like other drugs from this family is non subtype-selective muscarinic, and a nicotinic cholinoceptor antagonist, which has been employed in traditional Chinese medicine. As a muscarinic antagonist, it displays similar pharmacological effects to atropine and scopolamine. However, anisodamine is not only less potent than atropine and scopolamine but also less toxic. Current in vitro and animal model studies have demonstrated that anisodamine has protective effects in a variety of diseases. Organophosphate poisoning involves not only the central and peripheral nervous systems, but also the cardiac and respiratory systems, as well as activation of inflammatory processes and oxidative stress. Therefore, the anticholinergic and additional activities of anisodamine appear to be relevant and justify its consideration as an addition to the existing remedies. However, more research is needed, as at present data on the role of anisodamine in the management of organophosphate poisoning are limited. Here, we review the beneficial effects of anisodamine on processes relevant to organophosphate poisoning. PMID:27010563

    Cardiac glycosides are an important cause of poisoning, reflecting their widespread clinical usage and presence in natural sources. Poisoning can manifest as varying degrees of toxicity. Predominant clinical features include gastrointestinal signs, bradycardia and heart block. Death occurs from ventricular fibrillation or tachycardia. A wide range of treatments have been used, the more common including activated charcoal, atropine, β-adrenoceptor agonists, temporary pacing, anti-digoxin Fab and magnesium, and more novel agents include fructose-1,6-diphosphate (clinical trial in progress) and anticalin. However, even in the case of those treatments that have been in use for decades, there is debate regarding their efficacy, the indications and dosage that optimizes outcomes. This contributes to variability in use across the world. Another factor influencing usage is access. Barriers to access include the requirement for transfer to a specialized centre (for example, to receive temporary pacing) or financial resources (for example, anti-digoxin Fab in resource poor countries). Recent data suggest that existing methods for calculating the dose of anti-digoxin Fab in digoxin poisoning overstate the dose required, and that its efficacy may be minimal in patients with chronic digoxin poisoning. Cheaper and effective medicines are required, in particular for the treatment of yellow oleander poisoning which is problematic in resource poor countries. PMID:26505271

    Nearly 10,000 swans of six species or subspecies from 14 countries have died from poisoning caused by lead that originated from ingestion of fishing weights, shotgun pellets (shot), or contaminated vegetation or sediments associated with mining and smelting wastes. Lead contamination in mute swans in England caused local population declines during the late 1970s and 1980s. More tundra swans died from lead poisoning than any other species. The extreme record involved an estimated 7200 tundra swans that died over five winters at one locality in North Carolina. The recent legislation to ban lead fishing weights in most of England and Wales and recent replacement of lead shot with steel shot for waterfowl hunting in the United States and a few areas of Europe, including Denmark, are expected to reduce the incidence of lead poisoning in swans.

    Terrorist use of organophosphorus-based nerve agents and toxic industrial chemicals against civilian populations constitutes a real threat, as demonstrated by the terrorist attacks in Japan in the 1990 s or, even more recently, in the Syrian civil war. Thus, development of more effective countermeasures against acute organophosphorus poisoning is urgently needed. Here, we have generated and validated zebrafish models for mild, moderate and severe acute organophosphorus poisoning by exposing zebrafish larvae to different concentrations of the prototypic organophosphorus compound chlorpyrifos-oxon. Our results show that zebrafish models mimic most of the pathophysiological mechanisms behind this toxidrome in humans, including acetylcholinesterase inhibition, N-methyl-D-aspartate receptor activation, and calcium dysregulation as well as inflammatory and immune responses. The suitability of the zebrafish larvae to in vivo high-throughput screenings of small molecule libraries makes these models a valuable tool for identifying new drugs for multifunctional drug therapy against acute organophosphorus poisoning.

    In May and June 1986, 49 persons in Sierra Leone were acutely poisoned by the organothiophosphate insecticide, parathion. Fourteen people died. Illness occurred in three episodes at two different locations that were 44 km apart. A study of 21 cases and 22 household controls was undertaken to explore which factors were associated with the development of the symptoms. Cases were more likely than controls to have eaten bread in the 4 hours before becoming ill (odds ratio, 12.7; 95% confidence interval, 2.4-83.8). Scrapings of residue from the floor of the truck that had brought the wheat flour from the mill to the general store where the baker purchased it were positive for parathion, suggesting that the flour had been contaminated during transport. Pesticide poisoning is a common problem in the developing world, and public health measures such as restricting the use of parathion may help to prevent fatal poisonings. PMID:3501344

    Background Organophosphates and carbamates are insecticides that are associated with high human mortality. The purpose of this study is to investigate the prognostic factors affecting survival in patients with cholinesterase inhibitor (CI) poisoning. Material/Methods This study included 92 patients with CI poisoning in the period from January 2005 to August 2013. We divided these patients into 2 groups (survivors vs. non-survivors), compared their clinical characteristics, and analyzed the predictors of survival. Results The mean age of the included patients was 56 years (range, 16–88). The patients included 57 (62%) men and 35 (38%) women. When we compared clinical characteristics between the survivor group (n=81, 88%) and non-survivor group (n=11, 12%), there were no differences in renal function, pancreatic enzymes, or serum cholinesterase level, except for serum bicarbonate level and APACHE II score. The serum bicarbonate level was lower in non-survivors than in survivors (12.45±2.84 vs. 18.36±4.73, P<0.01). The serum APACHE II score was higher in non-survivors than in survivors (24.36±5.22 vs. 12.07±6.67, P<0.01). The development of pneumonia during hospitalization was higher in non-survivors than in survivors (n=9, 82% vs. n=31, 38%, P<0.01). In multiple logistic regression analysis, serum bicarbonate concentration, APACHE II score, and pneumonia during hospitalization were the important prognostic factors in patients with CI poisoning. Conclusions Serum bicarbonate and APACHE II score are useful prognostic factors in patients with CI poisoning. Furthermore, pneumonia during hospitalization was also important in predicting prognosis in patients with CI poisoning. Therefore, prevention and active treatment of pneumonia is important in the management of patients with CI poisoning. PMID:26411989

  6. Using Poison Center Data for Postdisaster Surveillance

    The role of public health surveillance in disaster response continues to expand as timely, accurate information is needed to mitigate the impact of disasters. Health surveillance after a disaster involves the rapid assessment of the distribution and determinants of disaster-related deaths, illnesses, and injuries in the affected population. Public health disaster surveillance is one mechanism that can provide information to identify health problems faced by the affected population, establish priorities for decision makers, and target interventions to meet specific needs. Public health surveillance traditionally relies on a wide variety of data sources and methods. Poison center (PC) data can serve as data sources of chemical exposures and poisonings during a disaster. In the US, a system of 57 regional PCs serves the entire population. Poison centers respond to poison-related questions from the public, health care professionals, and public health agencies. The Centers for Disease Control and Prevention (CDC) uses PC data during disasters for surveillance of disaster-related toxic exposures and associated illnesses to enhance situational awareness during disaster response and recovery. Poison center data can also be leveraged during a disaster by local and state public health to supplement existing surveillance systems. Augmenting traditional surveillance data (ie, emergency room visits and death records) with other data sources, such as PCs, allows for better characterization of disaster-related morbidity and mortality. Poison center data can be used during a disaster to detect outbreaks, monitor trends, track particular exposures, and characterize the epidemiology of the event. This timely and accurate information can be used to inform public health decision making during a disaster and mitigate future disaster-related morbidity and mortality. PMID:25205009

    1985-01-01

    Seasonal variation in carbon monoxide (CO) poisoning during 1969-78 was examined using the monthly hospital admissions and environmental weather data from Seoul, Korea. The results showed that there were nine times as many cases of CO poisoning in December as in August. CO poisoning cases were significantly correlated with temperature and domestic fires but not significantly with relative humidity. The epidemiological and clinical investigation of CO poisoning in the home needs to be studied in further detail. PMID:3989440

  8. Pharmacologic Strategies for Treatment of Poisonings.

    PubMed

    Roberts, Eric; Gooch, Michael D

    2016-03-01

    Poisoning is the leading cause of injury-related mortality in the United States. Data suggest that nonmedical use of pharmaceuticals is increasing, along with a proportional increase in subsequent adverse events. The widespread use of illegal drugs contributes to the challenge, because these drugs may produce a wide array of clinical presentations that warrant time-critical recognition and treatment. Common legal and illegal poisonings highlighting clinical presentations in terms of toxidromes as a means of categorically recognizing these emergencies is the focus of this article. To optimize outcomes for situations such as these, pharmacologic considerations are discussed and explored. PMID:26897424

    One hundred and three children with kerosene poisoning were studied. The majority of the patients were under five years of age and included a newborn baby. More patients were seen in spring and fewer in winter months. Most of the patients were children of poor families living in overcrowded conditions. Negligence and ignorance were the main causes of poisoning. Respiratory and central nervous systems were mainly involved. Chest X-ray abnormalities were frequently seen. The patients were treated symptomatically. Only one patient died, he had been in a coma on admission to the hospital. All other patients had rapid and complete recoveries. PMID:7567734

    2003-09-01

    The threat of weapons of mass destruction such as nerve agents has become real since last year. The medical community has established protocols for the rapid evacuation and decontamination of affected civilians. However, protocols for resuscitative measures or acute perioperative care in cases of life-saving surgical interventions in toxic-traumatized casualties are still lacking. The database concerning the effects of nerve agent poisoning in humans is limited, and is largely based on reports of unintentional exposures to pesticide organophosphate poisoning and similar chemical substances. In this review, we summarize the knowledge on the possible pharmacological interactions between nerve agents and acute care. PMID:12972890

    The case of a zoo keeper who was bitten on the left finger by a venomous snake (Vipera xanthina) is reported. The administration of antivenom prevented the development of systemic poisoning but had no effect on the extent of the local complications. A compartment syndrome with a concomitant severe reaction at the bite site required fasciotomy of the upper and lower arm. The extensor tendon of the involved finger ruptured spontaneously, many weeks after wound healing was completed. Therefore, delayed local complications following snake bites may occur, even if signs of systemic poisoning are missing. PMID:8150389

    Poisoning is the fifth leading cause of death from unintentional injury in the WHO European region, while Spain is in the group with a lower rate. Most involuntary poisonings occur in young children while they are at the home, due to unintentional ingestion of therapeutic drugs or household products. Of these, a large percentage is stored in non-original containers and/or within reach of children. In this article, the Committee on Safety and Non-Intentional Injury Prevention in Childhood of the Spanish Association of Pediatrics provides a series of recommendations, educational as well as legal, to prevent such cases.

    2014-06-01

    A key weapon in the insurgents' armamentarium against coalition and local security forces in Iraq and Afghanistan has been the use of anti-vehicle mines and improvised explosive devices (IEDs). Often directed against vehicle-borne troops, these devices, once detonated, transfer considerable amounts of energy through the vehicle to the occupants. This results in severe lower limb injuries that are frequently limb threatening. Fundamental to designing novel mitigation strategies is a requirement to understand the injury mechanism by developing appropriate injury modelling tools that are underpinned by the analysis of contemporary battlefield casualty data. This article aims to summarise our understanding of the clinical course of lower limb blast injuries from IEDs and its value in developing unique injury modelling test-beds to evaluate and produce the next generation of protective equipment for reducing the devastating effects of blast injury.

  1. Predicting Outcome in Acute Organophosphorus Poisoning with a Poison Severity Score or the Glasgow Coma Scale

    PubMed Central

    Davies, James O. J.; Eddleston, Michael; Buckley, Nick A.

    2008-01-01

    Background: Organophosphorus pesticide poisoning kills around 200,000 people each year, principally due to self poisoning in the Asia-Pacific region. Aim: We wished to assess whether patients at high risk of death could be identified accurately using clinical parameters soon after hospital admission. Design: We evaluated the usefulness of the International Program on Chemical Safety Poison Severity Score (IPCS PSS) and the Glasgow Coma Score (GCS) prospectively for predicting death in patients poisoned by organophosphorus pesticides. Methods: Data were collected as part of a multicentre cohort study in Sri Lanka. Study doctors saw all patients on admission, collecting data on pulse, blood pressure, pupil size, need for intubation, and GCS. Results: 1365 patients with a history of acute organophosphorus poisoning were included. Receiver operating characteristic (ROC) curves were calculated for the IPCS PSS and GCS on admission. The IPCS PSS and GCS had similar ROC area under the curves (AUC) and best cut points as determined by Youden's index (AUC/sensitivity/specificity 0.81/0.78/0.79 for IPCS PSS ≥ grade 2 and 0.84/0.79/0.79 for GCS ≤13). The predictive value varied with the pesticide ingested, being more accurate for dimethoate poisoning and less accurate for fenthion poisoning (GCS AUC 0.91 compared to 0.69). Conclusions: GCS and the IPCS PSS were similarly effective at predicting outcome. Patients presenting with a GCS ≤ 13 need intensive monitoring and treatment. However, the identity of the organophosphate must be taken into account since the half of all patients who died from fenthion poisoning only had mild symptoms at presentation. PMID:18319295

    Acute poisoning is a frequent accident in childhood, particularly in children under 4 years of age. This was a descriptive study with data collected from standardized forms of the Poison Control Center and patient record charts. All the cases of acute poisoning in children aged 0 to 14 years during the period 2008 to 2012 were selected. The variables studied comprised characteristics of the events and toxic agents, clinical development, and outcome. A total of 657 cases of acute poisoning, with higher frequency in the age-group from 1 to 4 years (48.7%) and male sex (53.4%), were recorded. The occurrences were accidental in 92% of the cases, and 5.8% were due to suicide attempts. Among the toxic agents, medications (28.5%), venomous animals (19.3%), nonvenomous animals (10%), household cleaning products (9.0%), and raticide agents (8.7%) predominated. The majority of cases were characterized as light (73.5%) and around 18% required hospitalization, and there was low lethality (0.5%). PMID:27335994

All the cases of acute poisoning in children aged 0 to 14 years during the period 2008 to 2012 were selected. The variables studied comprised characteristics of the events and toxic agents, clinical development, and outcome. A total of 657 cases of acute poisoning, with higher frequency in the age-group from 1 to 4 years (48.7%) and male sex (53.4%), were recorded. The occurrences were accidental in 92% of the cases, and 5.8% were due to suicide attempts. Among the toxic agents, medications (28.5%), venomous animals (19.3%), nonvenomous animals (10%), household cleaning products (9.0%), and raticide agents (8.7%) predominated. The majority of cases were characterized as light (73.5%) and around 18% required hospitalization, and there was low lethality (0.5%). PMID:27335994

    Every year, about 300,000 people die because of pesticide poisoning worldwide. The most common pesticide agents are organophosphates and phosphides, aluminium phosphide (AlP) in particular. AlP is known as a suicide poison that can easily be bought and has no effective antidote. Its toxicity results from the release of phosphine gas as the tablet gets into contact with moisture. Phosphine gas primarily affects the heart, lungs, gastrointestinal tract, and kidneys. Poisoning signs and symptoms include nausea, vomiting, restlessness, abdominal pain, palpitation, refractory shock, cardiac arrhythmias, pulmonary oedema, dyspnoea, cyanosis, and sensory alterations. Diagnosis is based on clinical suspicion, positive silver nitrate paper test to phosphine, and gastric aspirate and viscera biochemistry. Treatment includes early gastric lavage with potassium permanganate or a combination with coconut oil and sodium bicarbonate, administration of charcoal, and palliative care. Specific therapy includes intravenous magnesium sulphate and oral coconut oil. Moreover, acidosis can be treated with early intravenous administration of sodium bicarbonate, cardiogenic shock with fluid, vasopresor, and refractory cardiogenic shock with intra-aortic baloon pump or digoxin. Trimetazidine may also have a useful role in the treatment, because it can stop ventricular ectopic beats and bigeminy and preserve oxidative metabolism. This article reviews the epidemiological, toxicological, and clinical/pathological aspects of AlP poisoning and its management. PMID:22450207

    Endosulfan is a widely used insecticide that is associated with a high fatality rate in humans when ingested accidentally or with the aim of suicide. However, the literature concerning human endosulfan exposure is limited to case reports. Thus, we sought to 1) describe the clinical features of patients with acute endosulfan poisoning and 2) identify independent factors to predict patients' outcome. Fifty-two patients who presented with acute endosulfan poisoning between January 2001 and January 2007 were enrolled in this retrospective study. Sixteen (30.7%) of the 52 patients died, and 48 patients experienced seizures. Endosulfan poisoning caused the hypotension and the abnormalities on electrocardiogram at presentation. Over half of the patients developed complications, such as rhabdomyolysis, hepatic toxicity, and hypotension. These complications resolved without sequelae in the survival group. Refractory status epilepticus was the most common cause of death in this series (75.0%). Amount ingested being greater than 35 g of endosulfan was the most found to be an independent variable that predicted patient mortality. Patients with this risk factor must be treated aggressively during the early stage of endosulfan poisoning. PMID:19755461
