    The radiological accident happened in the Chilca District, the Canete County at 60 km to the south of Lima-Peru, during the night of January 11 to 12, 2012. The physical reconstruction of the accident was carried out in January 21, 2012, by means of the information gathering administrative and technical of the radioactive source as well as of the installation, the personnel and the involved procedures in the accidental event, information of the space geometry where the event took place. The preliminary information indicates that the source could have been locked in the guide tube of the equipment, next to the collimator in the first takes radiographic. The radiation monitors were not activated on the procedure, impeding this way, not to realize the flaw and causing that the personnel were exposed to the radiation during the whole work period. Their hands and especially their fingers would have been only to some millimeters of the source. With the obtained information and the measurements of the exposure rates of the radioactive source, was carried out the dose calculation to total body, the dose received in the hands and the dose received in the index finger of the left hand. The accident happened by operative procedure breach, by lack of training of the operators. The physical reconstruction of the accident contributes fundamental information for the decisions taking in the medical management of the accidents by radiation. (author)

    The greatest fear of the population before a nuclear accident, is the radiological impact to the health of people, due to the exposure to the liberated radioactive material during the accident, this fear is generally exaggerated or not well managed by the media. The best estimate in the received doses and their possible effects is carried out based on the information obtained during a certain time after the accident event. This work contains a summary of the information in the topic that at the present time has presented institutions as: the World Health Organization (Who), the United Nations Scientific Committee on Effects of Atomic Radiation (UNSCEAR), the Nuclear Regulatory Commission (NRC) and the World Nuclear Association, among others. The considered accidents are: first, the Unit-2 of the nuclear power plant of the Three Mile Island in Pennsylvania, USA occurred 28 March of 1979, in the Reactor TMI-2, type PWR of 900 M We; the second accident was 26 April of 1986, in the Unit-4 of the nuclear power plant of Chernobyl, in Ukraine, the involved reactor was type BRMK, of 1000 M We moderated by graphite and cooled with light water, the power plant is located to 100 Km to the northwest of Kiev; 25 years later occurred the third accident in the nuclear power plant of Fukushima Dai-ichi, in Japan, affecting at four of the six reactors of the power plant. A brief description of the accident is presented in each case, including the magnitude of the provoked liberations of radioactive material, the estimate doses of the population and the affected workers are presented, as well as the possible consequences of these doses on the health. The objective of this diffusion work is to give knowledge to the nuclear and radiological community of the available information on the topic, in order to be located in the appropriate professional context.

    On September 20, 2005 when a mission conformed by five (05) officials: two (02) belonging to the Ministry of Energy and Mines (MEP) and three (03) of the Ministry of Health (MS) it was prepared to carry out a routine inspection in the one temporary warehouse of sources in disuse located in La Ciudadela of El Cementerio, identified administratively as Warehouse Number 5 (MS) Area X, noticed that those armor-plating that kept the radioactive sources of Cs-137 had been violated. Those people that entered to the warehouse were able to extract the armor-plating in whose interior its were found an important number of sources of Cs-137 in disuse, used in the decade of 70 and 80 in treatment of cancer of the uterine neck, by means of the Brachytherapy technique of Differed charge manual, low dose rate, as well as, lead sheets with the apparent intention of selling them as junk. The intruders extracted a total of 58 radioactive sources of Cs-137 of its armor-plating for then to disperse them inside warehouse and in the external areas to this. An important number of the dispersed sources its had lost it integrity what gave place to a combined scenario of exposed dispersed sources in a public area with the danger of radioactive contamination by Cs-137. A task force conformed by the following institutions: Ministry of Health (MS), Ministry of Energy and Petroleum (MENPET), Venezuelan Institute of Scientific Investigations (IVIC), Unit of Dangerous Materials of the Metropolitan Firemen under the coordination of Civil Protection (PC) it was the one in charge of responding to the radiological accident, of conformity to the National Plan for the Answer to Radiological Accidents. All the radioactive sources dispersed in La Ciudadela achieved to be recovered. The experience of the accident and as learned lesson it was the importance of harmonizing the Generic Procedures for the Evaluation and Answer during Radiological Emergencies, IAEA-TECDOC-1162 technical document, Vienna, August 2000, with the procedures of the answering in charge of responding to accidents with dangerous materials.

    Derived of the radioactive or nuclear material management, exists the risk that accidents can happen where people cases are presented with internal radioactive contamination, who will receive specialized medical care to accelerate the radioactive dis incorporation with the purpose of diminishing the absorbed dose and the associate biological effects. In this work treatments of radioactive dis incorporation were identified, in function of the radionuclide, radiation type, radioactive half life, biological half life, critical organ, ingestion duct and patient type. The factor time is decisive for the effectiveness of the selected treatment in the blockade stage (before the accident) or dis incorporation (after the accident); this factor is related with the radioactive and biological half lives. So to achieve dis incorporation efficiencies of more to 70%, the patient clinical treatment will begin before the first third of the biological half life of the radionuclide that generated the internal contamination.

    We present several models where the QCD axion arises accidentally. Confining gauge theories can generate axion candidates whose properties are uniquely determined by the quantum numbers of the new fermions under the Standard Model. The Peccei-Quinn symmetry can emerge accidentally if the gauge theory is chiral. We generalise previous constructions in a unified framework. In some cases these models can be understood as the deconstruction of 5-dimensional gauge theories where the Peccei-Quinn symmetry is protected by locality but more general constructions are possible.

    Accidental matter models are scenarios where the beyond-the-standard model physics preserves all the standard model accidental and approximate symmetries up to a cutoff scale related with lepton number violation. We study such scenarios assuming that the new physics plays an active role in neutrino mass generation, and show that this unavoidably leads to radiatively induced neutrino masses. We systematically classify all possible models and determine their viability by studying electroweak precision data, big bang nucleosynthesis and electroweak perturbativity, finding that the latter places the most stringent constraints on the mass spectra. These results allow the identification of minimal radiative accidental matter models for which perturbativity is lost at high scales. We calculate radiative charged-lepton flavor violating processes in these setups, and show that μ→eγ has a rate well within MEG sensitivity provided the lepton-number violating scale is at or below 5×10{sup 5} GeV, a value (naturally) assured by the radiative suppression mechanism. Sizeable τ→μγ branching fractions within SuperKEKB sensitivity are possible for lower lepton-number breaking scales. We thus point out that these scenarios can be tested not only in direct searches but also in lepton flavor-violating experiments.

    We build models where Dark Matter candidates arise as composite states of a new confining gauge force, stable thanks to accidental symmetries. Restricting to renormalizable theories compatible with SU(5) unification, we find 13 models based on SU(N) gauge theories and 9 based on SO(N). We also describe other models that require non-renormalizable interactions. The two gauge groups lead to distinctive phenomenologies: SU(N) theories give complex DM, with potentially observable electric and magnetic dipole moments that lead to peculiar spin-independent cross sections; SO(N) theories give real DM, with challenging spin-dependent cross sections or inelastic scatterings. Models with Yukawa couplings also give rise to spin-independent direct detection mediated by the Higgs boson and to electric dipole moments for the electron. In some models DM has higher spin. Each model predicts a specific set of lighter composite scalars, possibly observable at colliders.

    In this paper a classification of the radiological and nuclear accidents is presented, describing which the activities are, where they have occurred, their incidence and the learned lessons in these successes. The radiological accidents in which radioactive materials intervene can occur anywhere, and they are related to no controlled dangerous sources (abandoned, lost, stolen, or found sources), improper use of dangerous industrial and medical sources, exposition and contamination of people in general by an unknown origin, serious over expositions, menaces and willful misconduct, emergencies during transportation of radioactive material. A person can receive a dose of radiation from an external source, because of radioactive material placed on skin or on equipment, or because of ingestion or inhalation of radiological particles. The ingestion or the inhalation of radioactive material can cause an internal dose to the whole body or to a specific organ during a period of time. That is why a description of the processes of incorporation, the stages of incorporation and a description of the biokinetic models are also realized to understand the ingestion, transference and the excretion of the radioactive elements. In order to offer help to a victim of internal contamination, the dosimetric and medical diagnosis is very important. The most important techniques of dosimetric diagnosis are the dosimetry in vivo (cytogenetics and the counting in vivo of the whole body) and the bioassays. These techniques allow obtain data such as the radionuclide, the target organ, the absorbed dose, etc. At the same time, the doctor in charge must be attentive to the patients symptoms and their manifestation time, since they are an indicator, first, the patient suffered an irradiation, and second, of the range esteem of the received radiation dose. These are the parameters that are useful as criterion to decide if a person has to receive some treatment and select the methodologies that allow obtain a better result of the dis incorporation of the radioactive material. In this work, the attention is focused on the identification, classification and selection of the methodologies to accelerate the dis incorporation of radionuclides in people related to nuclear a radiological accidents, depending on the way of incorporation to the human body, the radionuclide, the radiotoxicity, the kind of radiation and its energy, the chemical compound, the half-life of the radioisotope, the target organ, the esteem of the absorbed dose, the characteristic of the accident, the clinical state of the patient and how long ago the accident happened.

    The recent Fukushima accident has shown that the scientific community and the general public is very much interested in and concerned about knowing the possible current and future consequences that an accident of this nature can have in both the local population and the rest of the world. It also reveals that society, even though it is not directly affected, feels that it is affected and demands not only fast, effective responses from national authorities, but also a greater involvement of all international bodies related to Nuclear Safety and to Radiological Protection of the public and the environment and a better coordination between them.

    The Direccion de Vigilancia Radiologica (DVR) of the Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) de Mexico, performs several function for environmental radiation monitoring. One of these functions is the permanent monitoring of the environmental gamma radiation. For this, it implemented the Red Nacional Automatica de Monitoreo Radiologico Ambiental (RENAMORA) - the National Automated Network for Environmental Radiation Monitoring,which currently comprises 60 detector probes for gamma radiation which with a programmable system that includes information technologies, data transmission and software can send the information in real time to a primary center of data located in the facilities of CNSNS. - When the data are received, the system performs the verification and extraction of the information organized in Tables and charts, and generates a report of environmental gamma radiation dose rate average for each of the probes and for each period of time determined bu CNSNS. The RENAMORA covers the main cities and allows to establish the bases of almost the entire country, as well as to warn about abnormal situations caused by incidents or natural events generated by human activities inside or outside the country which involves radioactive materials; paying special attention to main radiological sites, such as the surroundings of the Laguna Verde Nuclear Power Plants, research centers and the radioactive waste disposal sites.

    2016-10-01

    Hypothermia, along with acidosis and coagulopathy, is part of the lethal triad that worsen the prognosis of severe trauma patients. While accidental hypothermia is easy to identify by a simple measurement, it is no less pernicious if it is not detected or treated in the initial phase of patient care. It is a multifactorial process and is a factor of mortality in severe trauma cases. The consequences of hypothermia are many: it modifies myocardial contractions and may induce arrhythmias; it contributes to trauma-induced coagulopathy; from an immunological point of view, it diminishes inflammatory response and increases the chance of pneumonia in the patient; it inhibits the elimination of anaesthetic drugs and can complicate the calculation of dosing requirements; and it leads to an over-estimation of coagulation factor activities. This review will detail the pathophysiological consequences of hypothermia, as well as the most recent principle recommendations in dealing with it. Copyright © 2016.

    Tracheostomy tube (TT) is usually removed in a planned manner once the patient ceases to have the condition that necessitated the procedure. Accidental decannulation or extubation refers to inadvertent removal of tracheostomy tube out of the stoma. It could prove fatal in an otherwise stable patient. We review a variety of unexpected and often-overlooked causes of accidental decannulation with suggestions on preventive measures. We therefore present three cases of accidental decannulation of tracheostomy tubes in order to report our experiences in the management of the condition. Accidental decannulation occurs both in hospitalized and patient on home care of their tracheostomy tubes. Reduction in neck circumference due to weight loss predisposes to accidental decannulation, which could be prevented by suturing the flange to the skin.

    An interesting case of accidental death involving the explosion of professional fireworks in an apartment is described. The examination of the scene permitted to study several effects of the explosion on walls, ceiling, furniture and especially on a balcony where the victim was found. The external examination of the victim showed extensive thermal injuries, degloving injuries and extensive shrapnel wounds. The autopsy examination showed subarachnoid haemorrhage localized to the cerebellum, haemorrhage in the soft tissues of the neck and chest and fracture of one clavicle. Almost the entire surface of lungs showed blunt injuries and the liver showed tearing of parenchyma and multiple cavities. Histological analysis were carried out showing thickening of alveolar septae, enlargement of alveolar spaces and alveolar ruptures in lung sections while numerous, round, empty spaces were detected in the parenchyma of the liver. The examination of the scene and of the fragments found showed that at least eight pyrotechnical charges exploded on the balcony, in close proximity of the threshold with the living room of the apartment. According to the chemical findings, the charges were typical for professional use and were filled with a mixture of potassium perchlorate and aluminium. A conservative calculation results in more than 1.5 kg total mass of pyrotechnic composition exploding very close to the victim. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    2010-02-01

    Full Text Available Abstract Background The incidence of methanol (CH3OH intoxication differs enormously from country to country. Methanol intoxication is extremely rare in the Dutch population. Even a low dose can already be potentially lethal. Patients are conventionally treated with hemodialysis. Therefore we'd like to present a report of a foreign sailor in Rotterdam who accidentally caused himself severe methanol intoxication, with a maximum measured concentration of 4.4 g/L. Case presentation The patient presented with hemodynamic instability and severe metabolic acidosis with pH 6.69. The anion gap was 39 mmol/L and the osmol gap 73 mosmol/kg. Treatment with ethanol and continuous venovenous hemodiafiltration (CVVH-DF was initiated. Despite the hemodynamic instability it is was possible to achieve rapid correction of pH and methanol concentration with CVVH-DF while maintaining a stable and therapeutic ethanol serum concentration. Despite hemodynamic and acid-base improvement, our patient developed massive cerebral edema leading to brain death. Permission for organ donation was unfortunately not ascertained. Conclusions We conclude that in a hemodynamic instable situation high methanol concentrations and methanol-induced derangements of homeostasis are safely and effectively treated with CVVH-DF and that severe cerebral edema is another possible cause of death rather than the classical bleeding in the putamen area.

  2. CROP - The Clinico-Radiologico-Ophthalmological Paradox in Multiple Sclerosis: Are Patterns of Retinal and MRI Changes Heterogeneous and Thus Not Predictable?

    Directory of Open Access Journals (Sweden)

    Fahmy Aboulenein-Djamshidian

    Full Text Available To date, no direct scientific evidence has been found linking tissue changes in multiple sclerosis (MS patients, such as demyelination, axonal destruction or gliosis, with either steady progression and/or stepwise accumulation of focal CNS lesions. Tissue changes such as reduction of the retinal nerve fiber layer (RNFL and the total macular volume (TMV, or brain- and spinal cord atrophy indicates an irreversible stage of tissue destruction. Whether these changes are found in all MS patients, and if there is a correlation with clinical disease state, remains controversial. The objective of our study was to determine, whether there was any correlation between the RNFL or TMV of patients with MS, and: (1 the lesion load along the visual pathways, (2 the ratios and absolute concentrations of metabolites in the normal-appearing white matter (NAWM, (3 standard brain atrophy indices, (4 disease activity or (5 disease duration.28 MS patients (RRMS, n = 23; secondary progressive MS (SPMS, n = 5 with moderately-high disease activity or long disease course were included in the study. We utilised: (1 magnetic resonance imaging (MRI and (2 -spectroscopy (MRS, both operating at 3 Tesla, and (3 high-resolution spectral domain-OCT with locked reference images and eye tracking mode to undertake the study.There was no consistency in the pattern of CNS metabolites, brain atrophy indices and the RNFL/TMV between individuals, which ranged from normal to markedly-reduced levels. Furthermore, there was no strict correlation between CNS metabolites, lesions along the visual pathways, atrophy indices, RNFL, TMV, disease duration or disability.Based on the findings of this study, we recommend that the concept of 'clinico-radiologico paradox' in multiple sclerosis be extended to CROP-'clinico-radiologico-ophthalmological paradox'. Furthermore, OCT data of MS patients should be interpreted with caution.

    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. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Se analizaron 1514 pacientes, 1079 (71% con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11% y 435 (29% con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%. Se registraron 38 muertes intrahospitalarias (17 ACV isquémicos y 21 ACV hemorrágicos, representando una mortalidad global del 2.5% (1.7% en ACV isquémicos y 4.8% en ACV hemorrágicos. No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.

  16. A Conjectured Bound on Accidental Symmetries

    CERN Document Server

    Buican, Matthew

    2012-01-01

    In this note, we study a large class of four-dimensional R-symmetric theories, and we describe a new quantity, \\tau_U, which is well-defined in these theories. Furthermore, we conjecture that this quantity is larger in the ultraviolet (UV) than in the infrared (IR), i.e. that \\tau_U^{UV}>\\tau_U^{IR}. While we do not prove this inequality in full generality, it is straightforward to show that our conjecture holds in the subset of theories that do not have accidental symmetries. In addition, we subject our inequality to an array of non-trivial tests in theories with accidental symmetries and dramatically different dynamics both in N=1 and N=2 supersymmetry and find that our inequality is obeyed. One interesting consequence of this conjecture is that the mixing of accidental symmetries with the IR superconformal R current is bounded by the UV quantity, \\tau_U^{UV}. To demonstrate the potential utility of this bound, we apply it to the somewhat mysterious SU(2) gauge theory of Intriligator, Seiberg, and Shenker a...

    2010-10-01

    Full Text Available Accidental radioisotope burns are rare. The major components of radiation injury are burns, interstitial pneumonitis, acute bone marrow suppression, acute renal failure and adult respiratory distress syndrome. Radiation burns, though localized in distribution, have systemic effects, and can be extremely difficult to heal, even after multiple surgeries. In a 25 year old male who sustained such trauma by accidental industrial exposure to Iridium192 the early presentation involved recurrent haematemesis, pancytopenia and bone marrow suppression. After three weeks he developed burns in contact areas in the left hand, left side of the chest, abdomen and right inguinal region. All except the inguinal wound healed spontaneously but the former became a non-healing ulcer. Pancytopenia and bone marrow depression followed. He was treated with morphine and NSAIDs, epidural buprinorphine and bupivicaine for pain relief, steroids, antibiotics followed by wound excision and reconstruction with tensor fascia lata(TFL flap. Patient had breakdown of abdominal scar later and it was excised with 0.5 cm margins up to the underlying muscle and the wound was covered by a latissimis dorsi flap. Further scar break down and recurrent ulcers occurred at different sites including left wrist, left thumb and right heel in the next two years which needed multiple surgical interventions.

    2016-01-01

    The modern surgical endodontic treatment is a safe and predictable procedure with high success rate. However, several factors can retard or impede the proper healing process. Use of a high speed handpiece during hard tissues management (osteotomy and apical resection) can potentially be one of these factors. Formation of metallic debris from the surgical diamond burs, production of necrotic local tissue due to overheating and the direct liberation of air from conventional handpiece into the working area are potential irritants able to delay the tissue healing. The aim of the present article is to report the histopathological findings of the trans-operational accidental contamination with oil in the surgical area during an endodontic surgery. PMID:27790269

    A three-month-old boy and an eight-month-old boy died from accidental positional asphyxia and hanging, respectively, after being placed to sleep unsupervised in stroller-prams. Both infants had moved down towards the fronts of the stroller-prams. The younger infant fell out when the footplate collapsed and he was found hanging from a metal bar on the side. The older infant had partly slipped through the front and was suspended with his head and arms within the stroller-pram and with his face pushed firmly into the mattress by a horizontal metal bar. Stroller-prams are a potentially dangerous sleeping environment unless infants are closely supervised, gaps in the front of stroller-prams closed and upright footplates stabilised.

    The clinical diagnostic signs for detecting inadvertent oesophageal intubation may all be misleading. We therefore tested the practice of recording exhaled carbon dioxide during the intubation procedure as an additional measure for detection of accidental oesophageal intubation. Twenty patients were intubated simultaneously into the trachea and oesophagus and the carbon dioxide concentration was continuously recorded from both sources. Manual ventilation of the lungs always resulted in a typical CO2 curve pattern. Ventilation by mask prior to the intubation obviously resulted in some filling the stomach by exhaled gas in 9 of the 20 patients. In these cases some CO2 could be detected during oesophageal ventilation. As the oesophageal CO2 concentrations were very low initially, compared to the tracheal recordings, and carbon dioxide completely disappeared after a few ventilations into the oesophagus, distinguishing between the tracheal and oesophageal capnography tracings was easy.

  13. Is the tri-bimaximal mixing accidental?

    CERN Document Server

    Abbas, Mohammed

    2010-01-01

    The Tri-bimaximal (TBM) mixing is not accidental if structures of the corresponding leptonic mass matrices follow immediately from certain (residual or broken) flavor symmetry. We develop a simple formalism which allows one to analyze effects of deviations of the lepton mixing from TBM on structure of the neutrino mass matrix and on underlying flavor symmetry. We show that possible deviations from the TBM mixing can lead to strong modifications of the mass matrix and strong violation of the TBM mass relations. As a result, the mass matrix may have an "anarchical" structure with random values of elements or it may have some symmetry which differs from the TBM symmetry. Interesting examples include matrices with texture zeros, matrices with certain "flavor alignment" as well as hierarchical matrices with a two-component structure, where the dominant and sub-dominant contributions have different symmetries. This opens up new approaches to understand the lepton mixing.

    1988-07-01

    Toxic, flammable, and explosive gases may be used in photovoltaic cell research laboratories and in commercial manufacturing facilities. Accidental release of these materials can present hazards to life and property. Accidents can arise from a variety of mechanical and human related failures. These can occur from the time materials are received at the loading dock of the facility to the time treated gases are discharged to the atmosphere through a stack. Each type of initiating event may require a different control approach. These may range from the training and certification of plant workers charged with the handling of gas cylinder hookups to installation of emergency pollution control systems. Since engineering options for controlling released materials are limited, emphasis should be placed on administrative and engineering approaches for preventing such accidents. These are likely to be the most effective approaches for protecting life and property.

    Full Text Available Accidental hypothermia refers to a state of lowering of core body temperature down to 35 ℃induced by drowning, burial in snow and prolonged exposure to cold environment, etc. Hypothermia may affect the cardiovascular system, respiratory system, digestive system, etc. The triad consisting "hypothermia, acidosis and coagulopathy" is an important factor accelerating the death of patients. Early, timely application of rewarming measures is regarded as the basic principle in treatment of hypothermia. A series of rewarming measures, such as infusion of warm fluids, inspiration of warm air, abdominal infusion of warm fluid, instruction of warm fluid into pleural cavity, intravenous infusion of warm fluid, rewarming through ECMO, etc. have been used recently. Advance in research on the classification of hypothermia, its impact to the body and the treatment methods are reviewed in present paper. DOI: 10.11855/j.issn.0577-7402.2016.04.15

    Full Text Available How do we define, discuss or assess aesthetics within a contemporary philosophical framework? The indefiniteness that accompanies attempts to formalize a definition of the aesthetic is a primary focus of this paper. This lack of a definition has occupied philosophers for hundreds of years in attempts to delineate the boundaries of an elusively formless concept. This formlessness speaks to the incredibly evasive character of such a pervasive feature recognized in both natural and artificial systems, agents and artefacts. With the rapid growth of artificially intelligent systems and an astounding diversity in computational creativity, in what ways may we approach aesthetics? How is the aesthetic recognized, determined and produced? This paper seeks to critically engage issues of non-human agency, inter-object relations, and aesthetic theory in relation to computational entities and autonomous systems. The ability of these systems to operate outside of human cognitive limitations including thought patterns and constructions which may preclude alternative aesthetic outcomes, afford them in some ways limitless potential in relation to aesthetics. The designation of the accidental or provisional is utilized as an alternative approach to the production and assessment of aesthetic occurrences of the non-human.

  19. Quick management of accidental tritium exposure cases.

    Singh, Vishwanath P; Badiger, N M; Managanvi, S S; Bhat, H R

    2012-07-01

    Removal half-life (RHL) of tritium is one of the best means for optimising medical treatment, reduction of committed effective dose (CED) and quick/easy handling of a large group of workers for medical treatment reference. The removal of tritium from the body depends on age, temperature, relative humidity and daily rainfall; so tritium removal rate, its follow-up and proper data analysis and recording are the best techniques for management of accidental acute tritium exposed cases. The decision of referring for medical treatment or medical intervention (MI) would be based on workers' tritium RHL history taken from their bodies at the facilities. The workers with tritium intake up to 1 ALI shall not be considered for medical treatment as it is a derived limit of annual total effective dose. The short-term MI may be considered for tritium intake of 1-10 ALI; however, if the results show intake ≥100 ALI, extended strong medical/therapeutic intervention may be recommended based on the severity of exposure for maximum CED reduction requirements and annual total effective dose limit. The methodology is very useful for pressurized heavy water reactors (PHWRs) which are mainly operated by Canada and India and future fusion reactor technologies. Proper management will optimise the cases for medical treatment and enhance public acceptance of nuclear fission and fusion reactor technologies.

    2014-06-01

    In this paper a drug fatality that involved an unintended drug delivery route is described. The decedent, a 23-year-old female in custody in a county jail on suspicion of a felony drug offense, was discovered in a holding cell unconscious and unresponsive. Following unsuccessful cardiopulmonary resuscitation attempts she was pronounced dead at the scene. At autopsy a wad of multiple small loosely wrapped plastic packages held together with another layer of clear plastic was found in the decedent's vagina. The smaller plastic packages contained an off-white pasty substance that was later identified as methamphetamine. Toxicological testing of specimens collected during autopsy revealed methamphetamine in the decedent's subclavian blood, vitreous fluid, and urine at extremely high concentrations (42.6, 20.1, and 771 mg/L, respectively). Amphetamine, the active metabolite of methamphetamine, was also present in the subclavian blood, vitreous fluid, and urine at significant concentrations (1.3, 0.5, and 20.4 mg/L, respectively). The cause of death was attributed to toxic effects of methamphetamine and the manner of death was ruled accidental. This report suggests that lethal concentrations of methamphetamine may be distributed to the systemic circulation via intravaginal absorption.

    Reports on accidental auto-injection of adrenaline are few. We encountered three cases of accidental injection of adrenaline. In this study, we have examined and reported the clinical courses and symptoms of our cases. CASE 1 involved a female physician in her 50s who had attended an explanatory meeting on auto-injection of adrenaline. She mistook EpiPen® to be the EpiPen trainer and accidentally injected herself with 0.3 mg EpiPen®. Her systolic/diastolic pressure peaked at 7 min to reach 144/78 mmHg and decreased to 120/77 mmHg at 14 min. Except for palpitation after 7 min, the only subjective symptom was local pain at the injection site. CASE 2 was noted in a 6-year-old boy. He accidentally pierced his right forefinger with 0.15 mg EpiPen®, and after 20 min, his right forefinger was swollen. The swelling improved 80 min after the accidental injection. CASE 3 was noted in a 4-year-old girl. She accidentally injected herself with 0.15 mg EpiPen®. Her systolic/diastolic pressure peaked at 23 min to reach 123/70 mmHg and decreased to 96/86 mmHg at 28 min. Severe adverse effects of accidental auto-injection of adrenaline were not observed in these three cases. Our findings suggest that while handling adrenaline auto-injectors, we should keep in mind the possibility of accidental injection.

    1996-01-01

    A two year prospective study was performed to determine the epidemiology of Munchausen syndrome by proxy, non-accidental poisoning, and non-accidental suffocation in the UK and the Republic of Ireland. Cases were notified to the British Paediatric Association Surveillance Unit from September 1992 to August 1994 if a formal case conference had been held for the first time during that period to discuss any of the above conditions. A total of 128 cases were identified: 55 suffered Munchausen syndrome by proxy alone, 15 poisoning, and 15 suffocation; 43 suffered more than one type of abuse. The majority of children were aged under 5 years, the median age being 20 months. On 85% of occasions the perpetrator was the child's mother. In 42% of families with more than one child, a sibling had previously suffered some form of abuse. Eighty five per cent of notifying paediatricians considered the probability of their diagnosis as virtually certain before a case conference was convened. The commonest drugs used to poison were anticonvulsants; opiates were the second commonest. Sixty eight children suffered severe illness of whom eight died. The combined annual incidence of these conditions in children aged under 16 years is at least 0.5/100,000, and for children aged under 1, at least 2.8/100,000. PMID:8813872

    Unintended accidental awareness during general anaesthesia represents failure of successful anaesthesia, and so has been the subject of numerous studies during the past decades. As return to consciousness is both difficult to describe and identify, the reported incidence rates vary widely. Similarly, a wide range of techniques have been employed to identify cases of accidental awareness. Studies which have used the isolated forearm technique to identify responsiveness to command during intended anaesthesia have shown remarkably high incidences of awareness. For example, the ConsCIOUS-1 study showed an incidence of responsiveness around the time of laryngoscopy of 1:25. On the other hand, the 5th Royal College of Anaesthetists National Audit Project, which reported the largest ever cohort of patients who had experienced accidental awareness, used a system to identify patients who spontaneously self-reported accidental awareness. In this latter study, the incidence of accidental awareness was 1:19,600. In the recently published SNAP-1 observational study, in which structured postoperative interviews were performed, the incidence was 1:800. In almost all reported cases of intra-operative responsiveness, there was no subsequent explicit recall of intra-operative events. To date, there is no evidence that this occurrence has any psychological consequences. Among patients who experience accidental awareness and can later remember details of their experience, the consequences are better known. In particular, when awareness occurs in a patient who has been given neuromuscular blocking agents, it may result in serious sequelae such as symptoms of post-traumatic stress disorder and a permanent aversion to surgery and anaesthesia, and is feared by patients and anaesthetists. In this article, the published literature on the incidence, consequences and management of accidental awareness under general anaesthesia with subsequent recall will be reviewed. © 2017 The Association

    To test young children’s false belief theory of mind in a morally relevant context, two experiments were conducted. In Experiment 1, children (N = 162) at 3.5, 5.5, and 7.5 years of age were administered 3 tasks: prototypic moral transgression task, false belief theory of mind task (ToM), and an “accidental transgressor” task, which measured a morally relevant false belief theory of mind (MoToM). Children who did not pass false belief ToM were more likely to attribute negative intentions to an accidental transgressor than children who passed false belief ToM, and to use moral reasons when blaming the accidental transgressor. In Experiment 2, children (N = 46) who did not pass false belief ToM viewed it as more acceptable to punish the accidental transgressor than did participants who passed false belief ToM. Findings are discussed in light of research on the emergence of moral judgment and theory of mind. PMID:21377148

    1998-04-30

    In the 1980s, many medical organizations identified the prevention of nuclear war as one of the medical profession's most important goals. An assessment of the current danger is warranted given the radically changed context of the post-Cold War era. We reviewed the recent literature on the status of nuclear arsenals and the risk of nuclear war. We then estimated the likely medical effects of a scenario identified by leading experts as posing a serious danger: an accidental launch of nuclear weapons. We assessed possible measures to reduce the risk of such an event. U.S. and Russian nuclear-weapons systems remain on a high-level alert status. This fact, combined with the aging of Russian technical systems, has recently increased the risk of an accidental nuclear attack. As a conservative estimate, an accidental intermediate-sized launch of weapons from a single Russian submarine would result in the deaths of 6,838,000 persons from firestorms in eight U.S. cities. Millions of other people would probably be exposed to potentially lethal radiation from fallout. An agreement to remove all nuclear missiles from high-level alert status and eliminate the capability of a rapid launch would put an end to this threat. The risk of an accidental nuclear attack has increased in recent years, threatening a public health disaster of unprecedented scale. Physicians and medical organizations should work actively to help build support for the policy changes that would prevent such a disaster.

  6. Leading global projects for professional and accidental project leaders

    CERN Document Server

    Moran, Robert T

    2008-01-01

    This book is a must-read for anyone responsible for projects and initiatives that span functional and geographical divides. Authors Moran and Youngdahl bring extensive experience and learning from industry practice to present a clear and straightforward treatment of the leadership skills and knowledge required to lead projects that are global in nature. They have written the first book of its kind to address the three essential skills of global project leaders - strategic project management, project leadership, and cross-cultural leadership. The authors argue that global project leadership is an essential skill in our project-based world and that we are all either intentional or accidental project leaders. Intentional project leaders pursue formal project management education and even certification whereas accidental project leaders find themselves leading global projects and initiatives as a result of a special assignment or promotion. Moran and Youndahl have found that the vast majority of global projects ...

  7. Accidental degeneracy of double Dirac cones in a phononic crystal

    KAUST Repository

    Chen, Ze-Guo

    2014-04-09

    Artificial honeycomb lattices with Dirac cone dispersion provide a macroscopic platform to study the massless Dirac quasiparticles and their novel geometric phases. In this paper, a quadruple-degenerate state is achieved at the center of the Brillouin zone in a two-dimensional honeycomb lattice phononic crystal, which is a result of accidental degeneracy of two double-degenerate states. In the vicinity of the quadruple-degenerate state, the dispersion relation is linear. Such quadruple degeneracy is analyzed by rigorous representation theory of groups. Using method, a reduced Hamiltonian is obtained to describe the linear Dirac dispersion relations of this quadruple-degenerate state, which is well consistent with the simulation results. Near such accidental degeneracy, we observe some unique properties in wave propagating, such as defect-insensitive propagating character and the Talbot effect.

Guidelines for the design and operation of effective post-release mitigation systems are also presented.

  10. La prevención de accidentes (3

    Chinchilla, M.

    1966-04-01

    Full Text Available The financial loss due to working accidents is very substantial, quite apart from the actual loss of human lives. Hence avoiding these accidents is a most important matter. The accident index in the various industries shows a rate of increase that is larger than should be the case in proportion to the development of the industries concerned, and the larger number of employees. The fact that these indexes are smaller in many countries, however, shows that these accidents can be considerably reduced if suitable measures are taken to avoid them. In chapter 2 of our magazine, issue no. 178, a variety of reasons were discussed that may originate accidents, although these causes are not directly linked to the accident itself. In this article mention is made of some of the measures that can be taken in the handling of cutting and welding equipment, and also of inflammable liquids, to prevent possible accidents.El peso de los accidentes de trabajo sobre la economía supone cantidades muy grandes que, independientemente del inestimable valor de una vida humana, realzan la importancia de la prevención de accidentes. Los índices de accidentes muestran en diferentes industrias un crecimiento mayor de lo que debería corresponder proporcionalmente, habida cuenta del crecimiento laboral. El hecho de que en distintos países los índices sean inferiores, demuestra que se pueden conseguir buenos frutos si se concede primordial importancia a que los trabajos se realicen con las debidas medidas de seguridad. En el Capítulo 2, número 178 de esta Revista, se detallaron diversas causas que pueden originar un accidente sin estar ligadas en forma directa con una tarea determinada. En el presente trabajo se indican algunas de las medidas que deben observarse en el manejo de los equipos de soldadura y corte, así como en el transvase de líquidos inflamables.

    Unexploded grenades are potentially dangerous materials. Numerous grenades have been found to be unexploded after wars have ended. We present an interesting case of an unexploded grenade that was found accidentally in a soldier's skull. On physical examination, the entrance wound of an unusual penetrating object was noted. This unusual physical finding led us to undertake radiographic examination. A 40-mm unexploded grenade was noticed on the radiograph of the soldier's skull.

    The application of lamp phosphors for accidental dosimetry is a new concept. Since the materials used in fluorescent lamps are good photo luminescent materials, if one can either use the inherent defects present in the phosphor or add suitable modifiers to induce thermoluminescence (TL) in these phosphors, then the device (fluorescent lamp) can be used as an accidental dosemeter. In continuation of our search for a suitable phosphor material, which can serve both as an efficient lamp phosphor and as a good radiation monitoring device, detailed examination has been carried out on cerium and terbium-doped lanthanum phosphate material. A (90)Sr beta source with 50 mCi strength (1.85 GBq) was used as the irradiation source for TL studies. The TL response as a function of dose received was examined for all phosphors used and it was observed that the intensity of the TL peak vs. dose received was a linear function in the dose range 0.1-200 Gy in each case. Incidentally LaPO(4): Ce,Tb is a component of the compact fluorescent lamp marketed recently as an energy bright light source. Besides having very good luminescence efficiency, good dosimetric properties of these phosphors render them useful for their use in accidental dosimetry also.

    Accidental ingestion of oral prescription drugs by children under age five continues to be a public health problem. A telephone survey of 1,866 ingestion incidents reported to nine poison control centers was conducted in the spring of 1986. Accidental ingestion occurred most often with a two-year-old child (42 per cent) in their own home (82 per cent). Thirty-five per cent of the toxic drugs ingested at home belonged to someone other than the immediate family, most often a grandparent. Toxic drugs were more often out of their usual storage location and in non-child-resistant prescription packaging, a nonprescription container, or in no container. Twenty-two per cent of all child-resistant packages were non-functional. Overall, at least 61 per cent of all medications had no child-resistant barrier at the time of ingestion. Accessible storage locations such as the kitchen counter, table top, or top of a dresser or bedside table greatly increased the risk of accidental ingestion. These results suggest the need for effective child-resistant packaging that is easier for all adults to use.

    To describe the successful treatment of accidental ethanol intoxication with hemodialysis in a dog. A 1.5-year-old female intact mixed breed dog was presented in a comatose state believed to be due to ethanol intoxication. The initial 9 hours of supportive care treatment were complicated by multiple seizures and hypothermia, and resulted in only minimal improvement in the dog's level of consciousness. Hemodialysis was implemented and resulted in rapid clinical recovery, corresponding to a rapid decline in serum ethanol concentration. To the authors' knowledge, this is the first reported case of using hemodialysis to treat accidental ethanol intoxication in a dog. The patient's initial serum ethanol concentration was higher than those previously reported for cases of accidental ethanol intoxication in dogs, and the serum ethanol concentration was shown to rapidly decline during hemodialysis. Treatment with hemodialysis for severe ethanol intoxication was effective in this case and may be able to decrease morbidity and mortality in some cases. © Veterinary Emergency and Critical Care Society 2011.

    non completamente risolto per talune condizioni patologiche, nelle quali i dati obiettivi ed anamnestici sono relativamente uniformi e il quadro radiologico privo di qualsiasi caratteristica. Materiale e metodi: Il materiale � costituito da sei casi di istiocitosi delle cellule di Langherans della mandibola osservati nell'arco di un decennio. Lo studio � basato sulla valutazione della documentazione radiologica tradizionale. Le radiografie sono state eseguite in proiezione latero-laterale-obliqua che, come noto, libera quasi completamente la porzione orizzontale della mandibola dalla sovrapposizione delle immagini di altre strutture ossee. Risultati: I risultati delle indagini radiologiche sono riportati nella tabella I. Si tratta di reticoloendoteliopatie capaci di dar luogo ad un processo granulomatoso costituito da polinucleati eosinofili, plasmacellule e linfociti e, fondamentalmente, da grandi cellule istiocitarie mononucleate dotate di attivit� granulopessica e fagocitaria, spiccatamente proliferanti nel tessuto osseo, identificabili con le cellule di Langherhans della pelle, delle mucose, degli spazi periodontali, del midollo osseo. Il tessuto granulomatoso che ne deriva si infiltra tra gli elementi costitutivi dell'organo colpito ed estendendosi comprime, atrofizza e tende a distruggere il tessuto, sostituendosi ad esso. Le alterazioni determinate dal granuloma isiocitario di Langherhans prevalgono nettamente nel sistema scheletrico e si verificano, in ordine di frequenza, nel cranio, nelle ossa lunghe dell'estremit�, nel piede, nelle coste e nella colonna vertebrale. L'interessamento della mucosa orale � eccezionale. Conclusioni: Nel granuloma istiocitario unifocale di Langherhans della mandibola l'indagine radiologica � indispensabile per l'approccio allo studio della tumefazione premandibolare fermo restando che la diagnosi di natura si basa esclusivamente sulla biopsia.

    Chlorine is a known pulmonary irritant gas that may cause acute damage in the respiratory system. In this paper, the socio-demographic and clinical characteristics of 39 accidentally exposed patients to chlorine gas are reported and different emergency treatment modalities are also discussed. Two emergency departments applications were retrospectively analyzed for evaluation of accidental chlorine gas exposure for year 2007. Patients were classified into 3 groups according to severity of clinical and laboratory findings based on the literature and duration of land of stay in the emergency department. The first group was slightly exposed (discharged within 6 hours), second group moderately exposed (treated and observed for 24 hours), and third group was severely exposed (hospitalized). Most of the patients were initially treated with a combination of humidified oxygen, corticosteroids, and bronchodilators. The average age was 17.03 ± 16.01 years (95% CI). Seven (17.9%) of them were female and 29 (74.4%) were children. Twenty-four patients (61.5%) were included in the first, nine (23.1%) were in second and six (15.4%) were in the third group. The presenting symptoms were cough, nausea, and vomiting and conjunctiva hyperemia for the first group, first groups symptoms plus dyspnea for the second group. Second groups symptoms plus palpitation, weakness and chest tightness were for the third group. Cough and dyspnea were seen in 64.1% and 30.8% of the patients respectively. No patients died. The authors recommend that non symptomatic or slightly exposed patients do not need any specific treatment or symptomatic treatment is sufficient.

    1992-11-21

    Aconitine and its related alkaloids are known cardiotoxins with no therapeutic role in modern western medicine. The rootstocks of Aconitum plants, which contain aconite alkaloids, have been common components of Chinese herbal recipes. We have documented life-threatening intoxication in 17 Chinese subjects after accidental herb-induced aconite poisoning. All patients developed symptoms of aconite toxicity within 2 h of herb ingestion. Most developed tachyarrhythmias, including ventricular tachycardia and fibrillation from which 2 patients died. Toxicological evaluation revealed that aconites from the Aconitum rootstocks were the only plausible casual factor for intoxication. These cases point to the need for strict surveillance of herbal substances with low safety margins.

Se aplicó un modelo de regresión logística para identificar los factores pronósticos de baja médica y determinar su probabilidad de ocurrencia . RESULTADOS: Las tasas más elevadas de AT se produjeron entre los trabajadores de cocina y lavandería (10,00 AT por 100 trabajadores-año. Los AT con baja médica mantienen una tendencia cercana a cero siendo febrero el mes con I.E más elevado (IE=139,8. Los que cursan sin baja médica tienen una tendencia positiva (r²=0,23, p<0,0001, siendo mayo el mes de mayor siniestralidad (IE=134,2. La probabilidad de que el accidente curse con baja médica aumenta significativamente con la edad, cuando se produce por la tarde, si ha tenido lugar en cocina/lavandería, y si se trata de un esguince o tendinitis. CONCLUSIONES: la actuación sobre la siniestralidad en los AT que cursen con IT, debería centrarse sobre los trabajos menos cualificados y en las áreas de cocina y lavandería.

  20. Method and apparatus for controlling accidental releases of tritium

    Science.gov (United States)

    Galloway, Terry R. [Berkeley, CA

    1980-04-01

    An improvement in a tritium control system based on a catalytic oxidation reactor wherein accidental releases of tritium into room air are controlled by flooding the catalytic oxidation reactor with hydrogen when the tritium concentration in the room air exceeds a specified limit. The sudden flooding with hydrogen heats the catalyst to a high temperature within seconds, thereby greatly increasing the catalytic oxidation rate of tritium to tritiated water vapor. Thus, the catalyst is heated only when needed. In addition to the heating effect, the hydrogen flow also swamps the tritium and further reduces the tritium release.

  2. Clinical perspectives on osteogenesis imperfecta versus non-accidental injury.

    Science.gov (United States)

    2015-12-01

    Although non-accidental injuries (NAI) are more common in cases of unexplained fractures than rare disorders such as osteogenesis imperfecta (OI), ruling out OI and other medical causes of fracture is always indicated. The majority of OI patients can be diagnosed with the help of family history, physical examination, and radiographic findings. In particular, there are a few radiological findings which are seen more commonly in NAI than in OI which may help guide clinician considerations regarding the probability of either of these diagnoses. At the same time, molecular testing still merits careful consideration in cases with unexplained fractures without obvious additional signs of abuse. © 2015 Wiley Periodicals, Inc.

    The accidental inhalation by two people of tritiated water is described. One person incorporated approximately 35 GBq (1 Ci) and was treated by forced diuresis. Her committed effective dose equivalent was approx. 0.4 Sv. The diuresis procedure and physiological monitoring of the patient is described. The other person incorporated only about 1 GBq (0.03 Ci) and accelerated his excretion of tritium by extra drinking. The clearance rates of tritium-in-urine are presented for both subjects and are used to estimate committed effective dose equivalents. These are compared with values from cytogenetic dosimetry derived from repeated blood sampling.

    Full Text Available Excessive ethanol consumption is a leading preventable cause of death in the United States. Much of the harm from ethanol comes from those who engage in excessive or hazardous drinking. Rectal absorption of ethanol bypasses the first pass metabolic effect, allowing for a higher concentration of blood ethanol to occur for a given volume of solution and, consequently, greater potential for central nervous system depression. However, accidental death is extremely rare with rectal administration. This case report describes an individual with klismaphilia whose death resulted from acute ethanol intoxication by rectal absorption of a wine enema.

    Full Text Available Mepivacaine is a potent local anaesthetic and used for infiltration and regional anaesthesia in adults and pediatric patients. Intoxications with mepivacaine affect mainly the CNS and the cardiovascular system. We present a case of accidental intravenous mepivacaine application and intoxication of an infant resulting in seizure, broad complex bradyarrhythmia, arterial hypotension and finally cardiac arrest. The patient could be rescued by prolonged resuscitations and a rapid initiation of ECMO and survived without neurological damage. The management strategies of this rare complication including promising other treatment options with lipid emulsions are discussed.

    2013-09-01

    Arisaema amurense is widely known in Korean folklore as a poisonous plant, and its lethal toxicity has long been recognized. The toxicity of Arisaema amurense is due to its content of calcium oxalate, which causes painful oropharyngeal edema, hypersalivation, aphonia, oral ulceration, esophageal erosion, and hypocalcemia. We report a case of accidental poisoning after ingestion of the rhizome of Arisaema amurense, resulting in airway obstruction that required endotracheal intubation. A 60-year-old man developed oral pain and swelling after accidentally ingesting a rhizome from the Arisaema amurense plant as a medicinal herb. His symptoms worsened upon his arrival in the Emergency Department, and he was unable to speak due to oral swelling and hypersalivation. The patient underwent endotracheal intubation to protect his airway and was treated with antihistamines and corticosteroids. Three days after treatment, he had improved and was extubated. We describe an emergent treatment course for a patient with acute airway obstruction resulting from the ingestion of Arisaema amurense. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Recently, the veterinarians are dealing with a number of cases that require forensic expertise. Such a circumstance could be the accidental electrocution in animals, one of the causes of unnatural death. There is a scarcity with reference to the pathological findings in veterinary forensic medicine. In this paper, we present the main lesions that occurred in a horse with accidental electrocution that was presented for complete necropsy survey. A horse corpse was sent to the Pathology Department (Faculty of Veterinary Medicine, Cluj-Napoca, Romania for a full medical survey. Preliminary results and external examination: the body was in rigor mortis; from the nasal cavities drained out reddish foam and in the mouth was observed the presence of ingested feed (straw that was not chewed, suggesting a quick death. The findings detected after internal examination of the carcass were poor blood coagulability, haemorrhagic diathesis throughout the body, with haemorrhages of various sizes in different body regions (e.g., muscles of the withers, in the gluteal muscle, the mucosa of epiglottis, larynx, trachea, in the interstitium of the lung, and ecchymosis in the left kidney. Some other lesions detected were infarcts and haemorrhages in the fundic region of the stomach’s mucosa. In electrocution, haemorrhages are most often located in the respiratory tract, aspect observed in our case too. However, the diagnosis of electrocution has to corroborate the necropsy findings (which are not specific, with some other data such as the fulminant death and inspection of power source.

    Full Text Available Este artículo presenta los resultados de una investigación sociológica cuyo objeto fue explorar el papel que ha jugado el modelo hegemónico de masculinidad en la ocurrencia de muertes derivadas de accidentes y varias formas de ejercicio de la violencia en una comunidad rural de la sierra de Sonora. Estos resultados difieren de aquellos que tradicionalmente los estudios de las masculinidades han mostrado para México y América Latina. El modelo dominante de masculinidad en las comunidades estudiadas no ha condicionado significativamente la ocurrencia de las muertes por accidentes y otras causas violentas. La responsabilidad, la disciplina y el respeto hacia las personas consideradas socialmente débiles (mujeres, ancianos y niños, principalmente son características que debe poseer un hombre de verdad en las comunidades estudiadas. El apego de los hombres a estas formas de comportamiento y su temor a perder honorabilidad como hombre de verdad si se desvían de estas normas de conducta los ha llevado a evitar una serie de prácticas temerarias que pudieron poner en riesgo su vida y la de otras personas.

  13. Accidental acute alcohol intoxication in infants: review and case report.

    Minera, Gabriella; Robinson, Evan

    2014-11-01

    Acute alcohol intoxication in children younger than 18 months old is both rarely documented and rarely fatal. Previous case reports suggest hypoglycemia and faster than normal rates of alcohol elimination found in children with acute alcohol intoxication compared with adults, but data are lacking. A 2-month-old infant presented with a decreased mental status after accidental ingestion of alcohol. He was diagnosed with acute alcohol intoxication, with a blood alcohol level of 330 mg/dL and was hyperglycemic (167 mg/dL). Alcohol elimination rate was calculated to be 21.6 mg/dL/h, similar to that in adults. To our knowledge, this case is the second youngest documented patient with accidental alcohol intoxication via ingestion in the United States. We present a rare case report of acute alcohol intoxication in an infant and a review of the literature. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although rare in the literature, poison control data suggests that alcohol poisoning in very young children is not rare. Emergency physicians should be prepared for the management of infants with alcohol poisoning. This case report and review brings attention to this subject and briefly discusses ethanol metabolism in infants. Copyright © 2014 Elsevier Inc. All rights reserved.

  14. Accidental childhood death and the role of the pathologist.

    Science.gov (United States)

    Byard, R W

    2000-01-01

    The following study provides an overview of accidental childhood death. This study is based on a review of 369 cases of fatal childhood accidents taken from the records of the Department of Histopathology, Women's and Children's Hospital, Adelaide, Australia, over a 34-year period from 1963 to 1996. Data provide information on deaths due to motor vehicle accidents, drownings, accidental asphyxia, burns, poisonings, electrocution, and miscellaneous trauma. In addition, certain categories have undergone further examination, including asphyxial deaths due to unsafe sleeping environments and unsafe eating practices, drowning deaths, and deaths on farms, following identification of significant child safety problems in these areas as part of the "Keeping Your Baby and Child Safe" program. Previously unrecognized dangers to children detected through this program include mesh-sided cots, V-shaped pillows, and certain types of stroller-prams. The production of information pamphlets and packages for parents and the recall of certain dangerous products following recommendations made by pathologists demonstrate that pediatric and forensic pathologists have an important role to play in preventive medicine issues and in formulating public health strategies.

  15. Accidental Peccei-Quinn Symmetry Protected to Arbitrary Order

    Di Luzio, Luca; Nardi, Enrico; Ubaldi, Lorenzo

    2017-07-01

    A S U (N )L×S U (N )R gauge theory for a scalar multiplet Y transforming in the bifundamental representation (N ,N ¯) preserves, for N >4 , an accidental U (1 ) symmetry first broken at operator dimension N . A vacuum expectation value for Y can break the symmetry to Hs=S U (N )L+R or to Hh=S U (N -1 )L×S U (N -1 )R×U (1 )L +R . In the first case the accidental U (1 ) gets also broken, yielding a pseudo-Nambu-Goldstone boson with mass suppression controlled by N . In the second case a global U (1 ) remains unbroken. The strong C P problem is solved by coupling Y to new fermions carrying color. The first case allows for a Peccei-Quinn solution with U (1 )PQ protected by the gauge symmetry up to order N . In the second case U (1 ) can get broken by condensates of the new strong dynamics, resulting in a composite axion. By coupling Y to fermions carrying only weak isospin, models for axionlike particles can be constructed.

    Full Text Available Purpose. To assess the frequency, risk factors, and management of accidental durotomy in minimally invasive transforaminal lumbar interbody fusion (MIS TLIF. Methods. This single-center study retrospectively investigates 372 patients who underwent MIS TLIF and were mobilized within 24 hours after surgery. The frequency of accidental durotomies, intraoperative closure technique, body mass index, and history of previous surgery was recorded. Results. We identified 32 accidental durotomies in 514 MIS TLIF levels (6.2%. Analysis showed a statistically significant relation of accidental durotomies to overweight patients (body mass index ≥25 kg/m2; P=0.0493. Patient age older than 65 years tended to be a positive predictor for accidental durotomies (P=0.0657. Mobilizing patients on the first postoperative day, we observed no durotomy-associated complications. Conclusions. The frequency of accidental durotomies in MIS TLIF is low, with overweight being a risk factor for accidental durotomies. The minimally invasive approach seems to minimize durotomy-associated complications (CSF leakage, pseudomeningocele because of the limited dead space in the soft tissue. Patients with accidental durotomy can usually be mobilized within 24 hours after MIS TLIF without increased risk. The minimally invasive TLIF technique might thus be beneficial in the prevention of postoperative immobilization-associated complications such as venous thromboembolism. This trial is registered with DRKS00006135.

    Full Text Available Anisakidosis is a zoonotic disease caused by the ingestion of nematodes belonging to the family of Anisakidae. Human infection is caused by intake of raw or undercooked sea fish and cephalopods infested by Anisakis larvae. We present a case of accidental endoscopic finding of an alive nematode adhering to distal ascending colon in a 32 years old man, submitted to colonoscopy owing to recent onsets of rectal bleeding of likely hemorrhoidal origin. The nematode, removed from colon by means of biopsy forceps, has been identified as L3 larvae of A. simplex by a light microscope. Histological examination of intestinal mucosa showed a mild fibrosis of lamina propria, characterized by focal lymphocytic inflammation and scattered infiltration of eosinophils. The patient reported the intake of marinated anchovies 3 days before endoscopic examination.

    The present paper reports studies on the applicability of fluorescent lamp phosphors in accidental radiation dosimetry. Strontium orthophosphate, which is used as one of the components in the fluorescent lamps, has been studied for its thermo-luminescence (TL) characteristics on exposure to different doses of beta irradiation. The analysis of the TL glow curve of the phosphor, with a well-defined glow peak at 553 K, and other experiments carried out have proved the utility of strontium orthophosphate as dosimetric material in the range of 10-200 Gy. It has been observed that the material satisfies most of the fundamental criteria for a good TLD-material. A fluorescent lamp developed with this material as TLD grade lamp phosphor is thus expected to serve twin purposes of providing illumination and monitoring the radiation released during a nuclear accident.

    The case is described of accidental irradiation of a male person with /sup 137/Cs of an activity of 24.71 GBq. The first estimate induced a reasonable suspicion that the absorbed dose could be very high and life-threatening. On the other hand the clinical picture, usual laboratory examinations, findings in the fluorescent blood count, the analysis of chromosomal count of lymphocytes in the peripheral blood, the spermiogram, and the negative post-irradiation porphyrinuria suggested that the absorbed dose could be much lower than the original estimate. The results of dosimetry obtained after the reconstruction of the accident by measuring on a phantom revealed that the actual dose was very close to that presumed from the results of biological dosimetry during the first days of examination of the patient.

    Full Text Available The study presented in this article describes a modern modeling methodology of the propagation of accidental flood waves in case a dam break; this methodology is applied in Romania for the first time for the pilot project „Breaking scenarios of Poiana Uzului dam”. The calculation programs used help us obtain a bidimensional calculation (2D of the propagation of flood waves, taking into consideration the diminishing of the flood wave on a normal direction to the main direction; this diminishing of the flood wave is important in the case of sinuous courses of water or with urban settlements very close to the minor river bed. In the case of Poiana Uzului dam, 2 scenarios were simulated with the help of Ph.D. Eng. Dan Stematiu, plausible scenarios but with very little chances of actually producing. The results were presented as animations with flooded surfaces at certain time steps successively.

    Full Text Available Formalin is a hazardous chemical that needs cautious handling and special storage. Owing to its disinfectant and fixative (i.e. for preserving pathologic tissue specimens in histopathology properties, it is widely used in dentistry. Although, the terms formaldehyde and formalin are often confused as being identical, these are different as to the concentrations of the primary component i.e. formaldehyde. In fact, the common fixative available as 10% neutral buffered formalin is actually a 4% solution of formaldehyde (i.e., a 10% solution made from a 37-40% commercially pure formaldehyde solution.

However, such inadequate therapeutic strategies can lead to cardiovascular complications including dilated cardiomyopathy. This study presents a case of a 65-year-old man after accidental ingestion of organic solvents (toluene and xylene, whose condition demonstrated all the criteria for diagnosis of myocardial infarction. The qualitative determinations of the above mentioned volatile organic compounds (VOCs in whole blood were carried out using a headspace sampling by means of gas chromatography. Cardiac catheterization revealed no specific coronary lesions, only a muscular bridge causing a 30–50% stenosis in the middle of the circumflex branch of the left coronary artery.

    2017-06-01

    We describe an unusual case of drowning in fluid other than water in an industrial setting. A 26-year-old man was working in an industry which performs surface treatment of mechanical steel parts with quenching oil. He fell into the quenching oil (which was hot due to immersion of red hot metal parts), and as he was working alone in the particular section, there was a fatal outcome. A medico-legal autopsy was performed. The causes of death were found to be multiple, with the association of drowning, extensive superficial burns and asphyxia due to laryngeal oedema. To our knowledge, it is the first report of drowning in hot quenching oil, and only nine previous observations of drowning in industrial environments have been reported in the international literature. Even though rare, these kinds of accidental deaths can be prevented in dangerous industries with proper precautions and strict adherence to standard operating procedures.

    In the present paper we present the consequences of an accidental occupational radiation exposure at a local hospital in Buenos Aires. Control at a local radiology service showed the lack of correct shielding in the X-ray equipment. The physicians and technicians (14 persons) exposed to radiation during 12 months were examined. The survey shows that: a) In 11 out of 14 radiation-exposed patients nodular goiter developed and an additional patient had diffuse goiter which means a goiter incidence of 85.7%; b) In 5 of the nodular goiter patients an increase in the size or the appearance of new nodules was observed along the follow-up period. No cancer was detected by FNA; c) Hypothyroidism was observed in 3/14 patients, and an additional patient had an abnormal TRH-TSH test, suggesting subclinical hypothyroidism; and d) Increased circulating antithyroid antibodies were found in one of the hypothyroid patients

    Seven different methods were used to estimate the dose rate to a female worker who was accidentally exposed in the neutron PHOENIX beamline at the IPNS. Theoretical and measured entrance dose ranged from 550 mrem/min to 2850 mrem/min. Theoretical estimates were based on a Monte Carlo simulation of a spectrum provided by IPNS (Crawford Spectrum). Dose measurements were made with TLDs on phantoms and with ionization chambers in a water phantom. Estimates of the whole body total effective dose equivalent (TEDE) rate ranged from 5.2 mrem/min to 840 mrem/min. Assumed and measured quality factors ranged from 2.6 to 11.8. Cytogenetic analyses of blood samples detected no positive exposure. The recommended TEDE rate was 158 mrem/min. The TEDE was 750 mrem.

    To evaluate the course and outcome of patients with accidental ocular alkali burns. Prospective, interventional case series. Study of a cohort of 16 patients (31 eyes) who sustained concomitant accidental sodium hydroxide ocular burns and received appropriate treatment at a tertiary care eye hospital in India. The patients were followed up for 1 year, and parameters including best-corrected visual acuity, epithelial defect area, conjunctival and limbal involvement, and injury-related complications were evaluated. Severe sodium hydroxide exposure of a mean duration of 12 ± 2.5 minutes and delay in specialist eye care caused moderate to severe injury (grade II, 19% [n = 6]; grade III, 19% [n = 6]; grade IV, 10% [n = 3]; and grade VI, 52% [n = 16]). Median best-corrected visual acuity at presentation was 1.0 logarithm of the minimal angle of resolution (logMAR) units (range, 0.3 to 1.9 logMAR units), and at 1 year, it was 1.0 logMAR units (range, 0 to 1.9 logMAR units; P = .121). The median initial epithelial defect was 100 mm(2) (range, 18 to 121 mm(2)), which healed in all eyes by 3.5 months. Initial median limbal involvement was 12 clock hours (range, 3 to 12 clock hours), resulting in a residual limbal stem cell deficiency of 6 clock hours (range, 0 to 12 clock hours) at 1 year. Most common complications were glaucoma and cataract. Corneal ulcers developed in 2 eyes, and keratolimbal graft was performed in 1 patient. Grade VI injuries had significantly worse outcome than the lower-grade injuries. The course and outcome of ocular alkali burns depends on effective first aid (including a thorough eyewash), age, initial grade of injury, response to treatment, prevention of secondary infection, and control of glaucoma. Despite appropriate treatment, these eyes responded poorly and carried a guarded visual prognosis. Copyright © 2012 Elsevier Inc. All rights reserved.

  12. Reporting a sudden death due to accidental gasoline inhalation.

    2012-02-10

    The investigation of uncertain fatalities requires accurate determination of the cause of death, with assessment of all factors that may have contributed to it. Gasoline is a complex and highly variable mixture of aliphatic and aromatic hydrocarbons that can lead to cardiac arrhythmias due to sensitization of the myocardium to catecholamines or acts as a simple asphyxiant if the vapors displace sufficient oxygen from the breathing atmosphere. This work describes a sudden occupational fatality involving gasoline. The importance of this petroleum distillate detection and its quantitative toxicological significance is discussed using a validated analytical method. A 51 year-old Caucasian healthy man without significant medical history was supervising the repairs of the telephone lines in a manhole near to a gas station. He died suddenly after inhaling gasoline vapors from an accidental leak. Extensive blistering and peeling of skin were observed on the skin of the face, neck, anterior chest, upper and lower extremities, and back. The internal examination showed a strong odor of gasoline, specially detected in the respiratory tract. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame ionization detector and confirmation was performed using gas chromatography-mass spectrometry. Disposition of gasoline in different tissues was as follows: heart blood, 35.7 mg/L; urine, not detected; vitreous humor, 1.9 mg/L; liver, 194.7 mg/kg; lung, 147.6 mg/kg; and gastric content, 116,6 mg/L (2.7 mg total). Based upon the toxicological data along with the autopsy findings, the cause of death was determined to be gasoline poisoning and the manner of death was accidental. We would like to alert on the importance of testing for gasoline, and in general for volatile hydrocarbons, in work-related sudden deaths involving inhalation of hydrocarbon vapors and/or exhaust fumes.

    Simonova, M.; Danihelka, P.

    2009-04-01

    Recently, the number of accidents happened, when floods trigger the releases of hazardous materials and following environment contamination. Baia Mare (Romania), Spolana Neratovice (Czech Republic) and hurricane Katrina (USA) are well known examples. The importance of this kind of phenomenon as a type of so called NATECH events is expressed among others in the Water Framework Directive 2000/60/EC, which reorganises water conservation in Europe. It requires programmes of protection measures to be drawn up not later than 2009, and in sub-article 11 (3) l b) to prevent and/or reduce the impact of accidental pollution incidents, for example as a result of floods. Effective measures demand the assessment of hazard and risk of accidental release triggered by floods and there is a need for the method which can be used for these purposes. Such a method is still missing and this is why the basic method for hazard assessment has been developed. Simple indexes-based method is composed of three segments (natural risks, technological risks and combined risk) and it has flexible, modular structure. First segment estimates the probability of flooding of installation, the second, based on the reference scenarios estimates the possibility of release of chemicals and the third classify consequences. The work on refining of parameters and method continues. Method can be used in prevention of major accidents in the framework of the Council Directive 96/82/EC on the control of major-accident hazards involving dangerous substances (Seveso II directive) and can help to complete the safety studies in classified establishments.

    Full Text Available Abstract Background Accidental poisoning is one of the leading causes of injury in the United States, second only to motor vehicle accidents. According to the Centers for Disease Control and Prevention, the rates of accidental poisoning mortality have been increasing in the past fourteen years nationally. In Texas, mortality rates from accidental poisoning have mirrored national trends, increasing linearly from 1981 to 2001. The purpose of this study was to determine if there are spatiotemporal clusters of accidental poisoning mortality among Texas counties, and if so, whether there are variations in clustering and risk according to gender and race/ethnicity. The Spatial Scan Statistic in combination with GIS software was used to identify potential clusters between 1980 and 2001 among Texas counties, and Poisson regression was used to evaluate risk differences. Results Several significant (p Conclusion The findings of the present study provide evidence for the existence of accidental poisoning mortality clusters in Texas, demonstrate the persistence of these clusters into the present decade, and show the spatiotemporal variations in risk and clustering of accidental poisoning deaths by gender and race/ethnicity. By quantifying disparities in accidental poisoning mortality by place, time and person, this study demonstrates the utility of the spatial scan statistic combined with GIS and regression methods in identifying priority areas for public health planning and resource allocation.

    Full Text Available Everyone prefers to work in those organizations where their dignity of human beings is respected. One of the most efficient means at the disposal of any firm, to improve the morale of the individual employees, and to establish a spirit of cooperation between the individual and the firm, is to set up a program of accident benefit. It will avoid direct and indirect losses due to working accidents, as analyzed in a previous article, and it will make it possible to improve total performance of each worker, since he will work in a more favorable environment, free from worry about potential danger to his person. It is almost impossible to describe in detail all those items that should be taken into account in a safety program. None the less, and as an indication of their diversity, some sources of danger are mentioned in this chapter, which are closely connected with human safety, such as public curiosity, travelling from one place to another, cleanliness and order.Todas las personas prefieren desempeñar sus tareas en aquellas organizaciones que tienen hacia ellos las consideraciones correspondientes a un ser humano. Uno de los medios más eficaces a disposición de cualquier empresa para elevar la moral del individuo y para crear un lazo de cooperación común entre el individuo y la empresa, es la de llevar a cabo un programa de prevención de accidentes, programa que redundará en el doble fruto: evitar las pérdidas directas e indirectas causadas por los accidentes de trabajo que se detallaron en un trabajo anterior, y conseguir aumentar el rendimiento del operario al hacerle un ambiente más grato por la preocupación que se demuestra hacia su persona. Es casi imposible detallar todos aquellos puntos que se deben tener en cuenta en un programa de seguridad; sin embargo, y como exponente de su diversidad, se señalan en este capítulo algunas causas, que, sin estar ligadas directamente con el trabajo individual, no obstante se encuentran

    Full Text Available We report a case of accidental cutaneous burns caused by salbutamol metered dose inhaler. A 9-year-old boy underwent dental extraction at a children's hospital and was incidentally noted to have burn injuries on dorsum of both hands. On questioning, the boy revealed that a few days ago his 14-year-old brother, who is an asthmatic, playfully sprayed his salbutamol metered dose inhaler on the back of both his hands with the inhaler's mouth piece being in direct contact with the patient's skin. On examination, there was a rectangular area of erythema with superficial peeling on the dorsum of both hands, the dimensions of which exactly matched those of the inhaler's mouthpiece. It is possible that the injury could have been a chemical burn from the pharmaceutical/preservative/propellant aerosol or due to the physical effect of severe cooling of the skin or mechanical abrasive effect of the aerosol blasts or a combination of some or all the above mechanisms. This case highlights the importance of informing children and parents of the potentially hazardous consequences of misusing a metered dose inhaler.

    The retention of aerosols by canopies of holm oak trees in a typical Mediterranean forest is studied. Firstly, dry deposition is measured both under and outside the canopy during several months. No clear differences are observed either in the amount or in the chemical composition of the particles collected under and outside the canopy. Secondly, the leaf morphology and anatomy as well as the aerosol deposited onto the leaf surfaces are studied by scanning electron microscopy. Cuticle thickness is measured and differences are observed between young and old leaves. The distribution of aerosol particles over leaf surface is also established. Finally, the possible incorporation into leaves of a radioactive aerosol released in an accidental situation is studied, by means of a sequential extraction procedure using water and an organic solvent. From the results it can be deduced that neither the abiotic layer nor the cuticle play any important role in the retention of caesium. The studied radionuclides are mainly found in particulate form, soluble in water, or incorporated into leaves.

    Full Text Available Background. 4-Aminopyridine (4-AP is a drug that is used to improve motor fatigue in patients suffering from multiple sclerosis (MS. Medication error can occur, as commercial preparation may not be available in some countries. Case Presentation. A 58-year-old woman with progressive MS presented with status epilepticus. She was receiving 4-AP for more than 3 years. The symptoms started soon after the ingestion of a single pill that was supposed to contain 10 mg 4-AP, but further investigations revealed that each pill had been inadvertently prepared with an 100 mg 4-AP concentration. The patient was admitted to the intensive care unit (ICU for appropriate management (orotracheal intubation, sedation, and antiepileptic drugs. The first electroencephalogram (EEG showed abundant irregular spike-waves on the left central regions. Neurological condition gradually improved from day 7, while the EEG did not reveal any more electrical seizures but was still consistent with toxic encephalopathy. The patient stayed in the ICU until day 13. At discharge from the rehabilitation ward (2.5 months later, the patient had not yet recovered her previous cognitive and functional condition. Conclusion. A single 100 mg 4-AP accidental overdose may cause serious immediate complications, with a slow and incomplete neurological recovery.

    RECUPERARE method has been developed for operating feedback analysis and built on the French Human Reliability Analysis (HRA) principles. It is used to study the causes of human errors or technical failures occurred in French PWRs and the recovery process of events. Based on an event classification (6 categories) model according to the nature of the link between failure and recovery, the identified and recorded data are: the causes of the defects (technical, human, organizational) and the context in which they appear; the factors of the recovery performance (depending on technical and organizational aspects); a chronological analysis, designed to collect delays between failures and their detection/recovery for each event. About 3600 events reported in French PWRs (1997-2003) had been reviewed through this model. Initially, the weight of factors and the most important factors, which influenced the detection and recovery delay, are defined. For this purpose, the regression Partial Least Square (PLS) is used. Then, to link RECUPERARE results with pre-accidental data, conditional probabilities of events linked between them by a cause and effect relationship are calculated. For this, the Bayesian method with the Bayesian network is built with the PLS obtained results and applied. This constitutes a first approach to take into account in HRA the human and organizational factors highlighted by operating feedback. (author)

    2014-01-01

    Lead (Pb) exposure in dairy cattle is associated with economic losses due to mortality and treatment costs, but with production animals there is also risk to the human food chain. The first objective of this study was to quantify the Pb concentration in milk from Pb-exposed cattle. The second objective was to correlate blood and milk Pb concentrations from individual cows. The third objective was long-term monitoring to determine the duration of milk contamination after exposure ceased. A dairy herd of more than 100 cows was accidentally exposed to Pb-contaminated feed. Milk and blood were collected for Pb analysis. Serial collection of milk samples continued for 2.5 years. The initial concentration of Pb in bulk tank milk was 0.0999 mg l⁻¹. The highest milk Pb concentration from an individual cow was 0.4657 mg l⁻¹ and the highest blood Pb concentration was 1.216 mg l⁻¹. One milk sample collected at the end of the study (day 922) contained 0.0117 mg Pb l⁻¹ of Pb. The calculated relationship between milk (y) and blood (x) Pb concentration was ln(y) = 3.4(x) - 2.21 (R² = 0.98).

    Full Text Available The paper describes a fatal case of accidental ingestion of a mixture of hydrochloric acid and hydrofluoric acid. The man was admitted to hospital, where appropriate treatment, adequate to his condition, was instituted. Numerous ventricular fibrillation episodes, for which the patient was defibrillated repeatedly, were observed during the period of hospitalization. The patient was in a critical condition, with progressive symptoms of hypovolemic shock and multiorgan failure. On the next day after admission, signs of electromechanical dissociation progressing to asystole were noted. The instituted resuscitation procedure proved ineffective and the patient died. Autopsy revealed brownish discoloration of the esophageal, gastric, and small intestinal mucous membranes. Numerous ulcerations without signs of perforation were found both in the esophagus and in the stomach. The mucous membrane of the small intestine demonstrated focal rubefactions, whereas no focal lesions of the large intestinal mucosa were seen. Microscopic investigation of the biopsy specimens collected from the stomach, duodenum and small intestine revealed mucous membrane necrosis foci, reaching the deeper layers of the wall of these organs. The mucous membrane of the large intestine was congested. Bioptates obtained from the lungs indicated the presence of hemorrhagic infarcts and focal extravasations. Poisoning with the aforementioned acids with consequent necrosis of the esophageal, gastric, duodenal and small intestinal walls with hemorrhages to the gastrointestinal tract, as well as extravasations and hemorrhagic infarcts in the lungs was considered to be the cause of death.

    There is a serious need to develop effective mitigators against accidental radiation exposures. In radiation accidents, many people may receive nonuniform whole-body or partial-body irradiation. The lung is one of the more radiosensitive organs, demonstrating pneumonitis and fibrosis that are believed to develop at least partially because of radiation-induced chronic inflammation. Here we addressed the crucial questions of how damage to the lung can be mitigated and whether the response is affected by irradiation to the rest of the body. We examined the widely used dietary supplement genistein given at two dietary levels (750 or 3750 mg/kg) to Fischer rats irradiated with 12 Gy to the lung or 8 Gy to the lung + 4 Gy to the whole body excluding the head and tail (whole torso). We found that genistein had promising mitigating effects on oxidative damage, pneumonitis and fibrosis even at late times (36 weeks) when drug treatment was initiated 1 week after irradiation and stopped at 28 weeks postirradiation. The higher dose of genistein showed no greater beneficial effect. Combined lung and whole-torso irradiation caused more lung-related severe morbidity resulting in euthanasia of the animals than lung irradiation alone. PMID:22013884

    Wildfires take a heavy toll on human health worldwide. Climate change may increase the risk of wildfire frequency. Therefore, in view of adapted preventive actions, there is an urgent need to further understand the health effects and public awareness of wildfires. We conducted a systematic review of non-accidental health impacts of wildfire and incorporated lessons learned from recent experiences. Based on the literature, various studies have established the relationship between one of the major components of wildfire, particulate matter (particles with diameter less than 10 µm (PM10) and less than 2.5 µm (PM2.5)) and cardiorespiratory symptoms in terms of Emergency Rooms visits and hospital admissions. Associations between wildfire emissions and various subclinical effects have also been established. However, few relationships between wildfire emissions and mortality have been observed. Certain segments of the population may be particularly vulnerable to smoke-related health risks. Among them, people with pre-existing cardiopulmonary conditions, the elderly, smokers and, for professional reasons, firefighters. Potential action mechanisms have been highlighted. Overall, more research is needed to better understand health impact of wildfire exposure.

    Abdelilah Ghannam

    2014-12-01

    Full Text Available Flecainide acetate is an antiarrhythmic drug used in the treatment of supraventricular arrhythmias. Flecainide causes very rare but often serious intoxications. These intoxications happen either due to a non-accidental overdose or because of a narrow therapeutic index in a patient who suffers from cardiomyopathy or has electrolyte abnormalities. We report an original case of a patient who had taken a high dose of flecainide with the aim of suicide. The patient suffered a cardiogenic shock with complications of lactic metabolic acidosis. Fast diagnosis is essential to reduce the high morbidity and mortality of this intoxication. The treatment plan is symptomatic. It aims at eliminating the poison and compensating cardiac function by treating the shock and the electrolyte imbalances. This allowed us to swiftly regain normal electrical and mechanical cardiac function in our patient. 3 weeks after the psychiatric consultation no sequelae were found. This case highlights that thorough history is essential in order to determine the diagnosis of a drug intoxication since the range of used products is wide. On the other hand, in case of any intoxication, while we apply a specific treatment, a well-managed, systematic, symptomatic treatment is essential to reduce morbidity and mortality.

    2009-01-01

    Introduction Epinephrine autoinjector devices are used with increasing frequency to treat severe anaphylactic reactions. Accidental injection, usually involving a finger, is a potential complication. Case presentation A physician in a Family Practice training program accidentally injected epinephrine into his left thumb while reading the operating instructions of an autoinjector (Epipen®). He developed swelling, pallor, and pain in the thumb. Treatment included topical nitroglycerin, oral vasodilators and warming of the thumb. As expected, none caused an immediate response; however, after 8 hours, the thumb was pink and warm. There was full recovery 2 months after the accident. We reviewed the treatment of accidental epinephrine injection, and found that the use of parenteral adrenergic alpha blocker phentolamine would have produced immediate recovery. Conclusions All health professionals concerned with the use of epinephrine autoinjectors should receive adequate instruction on their use. A regimen for management of accidental epinephrine injection, in particular the use of phentolamine, should be emphasized. PMID:19830160

    Objectives The aims of this study were to (i) investigate the association between night work or long work weeks and the risk of accidental injuries and (ii) test if the association is affected by age, sex or socioeconomic status. Methods The study population was drawn from the Danish version of the European Labour Force Survey from 1999-2013. The current study was based on 150 438 participants (53% men and 47% women). Data on accidental injuries were obtained at individual level from national health registers. We included all 20-59-year-old employees working ≥32 hours a week at the time of the interview. We used Poisson regression to estimate the relative rates (RR) of accidental injuries as a function of night work or long work weeks (>40 hours per week) adjusted for year of interview, sex, age, socioeconomic status (SES), industry, and weekly working hours or night work. Age, sex and SES were included as two-way interactions. Results We observed 23 495 cases of accidental injuries based on 273 700 person years at risk. Exposure to night work was statistically significantly associated with accidental injuries (RR 1.11, 99% CI 1.06-1.17) compared to participants with no recent night work. No associations were found between long work weeks (>40 hours) and accidental injuries. Conclusion We found a modest increased risk of accidental injuries when reporting night work. No associations between long work weeks and risk of accidental injuries were observed. Age, sex and SES showed no trends when included as two-way interactions.

    Patterns of accidental poisoning in children are changing dramatically. A five year population study (1977-81) was undertaken in urban children from Brisbane (population 1 000 000). A total of 2098 children were poisoned during this period with only one fatality, which represents a dramatic reduction in mortality. Over the past 15 years (1968-82) 13 children have died from accidental poisoning from this population, and two were murdered with drugs. A study of secular trends has indicated that...

    Highlights: • Conservative early dose of different unit fusion radioactivity release were assessed. • Data of accident level in INES for fusion reactor were proposed. • Method of environmental restoration time after fusion accident was proposed. • The maximum possible accident level for ITER like fusion reactor is 6. • We need 34–52 years to live after the fusion hypothetical accident. - Abstract: As an important index shaping the design of fusion safety system, evaluation of public radiation consequences have risen as a hot topic on the way to develop fusion energy. In this work, the comprehensive public early dose was evaluated due to unit gram tritium (HT/HTO), activated dust, activated corrosion products (ACPs) and activated gases accidental release from ITER like fusion reactor. Meanwhile, considering that we cannot completely eliminate the occurrence likelihood of multi-failure of vacuum vessel and tokamak building, we conservatively evaluated the public radiation consequences and environment restoration after the worst hypothetical accident preliminarily. The comparison results show early dose of different unit radioactivity release under different conditions. After further performing the radiation consequences, we find it possible that the hypothetical accident for ITER like fusion reactor would result in a level 6 accident according to INES, not appear level 7 like Chernobyl or Fukushima accidents. And from the point of environment restoration, we need at least 69 years for case 1 (1 kg HTO and 1000 kg dust release) and 34–52 years for case 2 (1 kg HTO and 10kg–100 kg dust release) to wait the contaminated zone drop below the general public safety limit (1mSv per year) before it is suitable for human habitation.

    Exposure to metallic mercury can cause severe accidental intoxications in children, whose clinical symptoms can vary depending on the route of administration, the dose, as well as the time and duration of the exposure. It has become unusual in France, yet it must be considered when taking a patient's medical history in cases of multisystemic involvement without a clear explanation. We report the case of a 12-year-old patient hospitalized because of a cough, poor general condition, chills, night sweats, psychomotor retardation, and skin lesions that had been developing for several weeks. The initial clinical examination also revealed sinus tachycardia, arterial hypertension, and abolition of osteotendinous reflexes. Complementary examination results were normal apart from a glomerular proteinuria without renal failure. When interviewing the mother, she reported that the child had played with mercury balls 3 months earlier. The suspicion of poisoning was confirmed by blood and urine analysis as well as renal biopsy showing an aspect of membranous glomerulonephritis with IgG and C3 depositions. An intoxication via a transdermal route being unlikely on healthy skin, the Regional Health Agency's survey concluded that chronic intoxication had occurred by inhalation of the mercury spread on the floor at the time of the exposure, which was then vacuum cleaned and released again by the contaminated vacuum cleaner. The patient's outcome was favorable within a few weeks after initiating DMSA chelation therapy. Mercury poisoning should be considered in cases of a multisystemic disorder without clear explanation, in order to intervene quickly and thus prevent irreversible renal and neurological consequences.

    Full Text Available Background Infectious causes of childhood deaths in the world have decreased substantially in the 21st century. This trend has exposed accidental deaths as an increasingly important future challenge. Presently, little is known about the cause structure of accidental childhood deaths in low– and middle–income country (LMIC settings In this paper, we aim to establish cause structure for accidental deaths in children aged 0–4 years in China in the year 2010. Methods In this paper, we explored the database of 208 multi–cause child mortality studies in Chinese that formed a basis for the first published estimate of the causes of child deaths in China (for the year 2008. Only five of those studies identified specific causes of accidental deaths. Because of this, we searched the Chinese medical literature databases CNKI and WanFang for single–cause mortality studies that were focused on accidental deaths. We identified 71 further studies that provided specific causes for accidental deaths. We used epidemiological modeling to estimate the number of accidental child deaths in China in 2010 and to assign those deaths to specific causes. Results In 2010, we estimated 314 581 deaths in children 0–4 years in China, of which 31 633 (10.1% were accidental. Accidental deaths contributed 7240 (4.0% of all deaths in neonatal period, 8838 (10.5% among all post–neonatal infant deaths, and 15 554 (31.7% among children with 1–4 years of age. Among four tested models, the most predictive was used to establish the likely cause structure of accidental deaths in China. We estimated that asphyxia caused 9490 (95% confidence interval (CI 8224–11 072, drowning 5694 (95% CI 5061–6327, traffic accidents 3796 (95% CI3163–4745, poisoning 3163 (95% CI 2531–3796 and falls 2531 (95% CI 2214–3163 deaths. Based on medians from a few rare studies, we also predict 633 (95% CI 316–1265 deaths to be due to burns and 316 (95% CI 0–633 due to falling objects

    Full Text Available The purpose of this study was to examine county and state-level accidental poisoning mortality trends in Pennsylvania from 1979 to 2014.Crude and age-adjusted death rates were formed for age group, race, sex, and county for accidental poisonings (ICD 10 codes X40-X49 from 1979 to 2014 for ages 15+ using the Mortality and Population Data System housed at the University of Pittsburgh. Rate ratios were calculated comparing rates from 1979 to 2014, overall and by sex, age group, and race. Joinpoint regression was used to detect statistically significant changes in trends of age-adjusted mortality rates.Rate ratios for accidental poisoning mortality in Pennsylvania increased more than 14-fold from 1979 to 2014. The largest rate ratios were among 35-44 year olds, females, and White adults. The highest accidental poisoning mortality rates were found in the counties of Southwestern Pennsylvania, those surrounding Philadelphia, and those in Northeast Pennsylvania near Scranton.The patterns and locations of accidental poisoning mortality by race, sex, and age group provide direction for interventions and policy makers. In particular, this study found the highest rate ratios in PA among females, whites, and the age group 35-44.

    Trauma is a leading cause of death among children worldwide. Detailed knowledge of the epidemiology of childhood fatal injuries is necessary for preventing injuries. To determine clinical differences between children who were treated in an emergency department for accidental or abusive injuries. A retrospective review of all deceased patients who were treated in two urban pediatric emergency departments between 1998 and 2010 was performed. Patients were categorized into two groups, accidental and abusive, for comparison. A total of 1498 patients died during the study period, with 124 deaths being attributable to injury for a rate of 9.5 injury-related deaths per year. Most fatal injuries were accidental. Children with abusive fatal injuries were younger and more likely to have been seen for an injury in a clinic or emergency department within 2 months of their death. Eighty-two percent of abusive fatal injuries had documented subdural hematomas, whereas only 7.2% of accidental fatal injuries had a subdural hematoma documented. Nearly 50% of abusive fatal injuries had retinal hemorrhages reported, although no child with an accidental fatal injury had this type of injury documented. Younger children, especially those previously seen in an emergency department or clinic for injury, are more likely to sustain an abusive fatal injury. Sentinel physical findings associated with abusive fatal injuries include subdural hematomas and retinal hemorrhages, and the presence of these findings should prompt an investigation into the circumstances of injury.

Demographic data and burn characteristics of 61 domestic environment burn victims were collected. The family members of 13 children and one aged adult, who needed supervision or special care, were selected to answer a semi-structured interview. Two thematic groups were identified: social and environmental factors that might have contributed to the burn accidents and circumstances involving the accidents. Risk factors were: low socioeconomic and educational levels of mothers and those responsible for the children at the moment of the accident, small houses considering the number of occupants and unsafe kitchen equipment. Although cases of domestic violence were not identified there was neglect from caregivers. Health professionals should be attentive and investigate the circumstances of accidents involving vulnerable individuals.Este estudio tuvo como objetivos caracterizar los accidentes por quemaduras, ocurridos en ambiente doméstico, e identificar las circunstancias de esos accidentes cuando afectaron niños, adultos o ancianos que necesitaban de supervisión.

  11. Innocent intentions: a correlation between forgiveness for accidental harm and neural activity.

    Contemporary moral psychology often emphasizes the universality of moral judgments. Across age, gender, religion and ethnicity, people's judgments on classic dilemmas are sensitive to the same moral principles. In many cases, moral judgments depend not only on the outcome of the action, but on the agent's beliefs and intentions at the time of action. For example, we blame agents who attempt but fail to harm others, while generally forgiving agents who harm others accidentally and unknowingly. Nevertheless, as we report here, there are individual differences in the extent to which observers exculpate agents for accidental harms. Furthermore, we find that the extent to which innocent intentions are taken to mitigate blame for accidental harms is correlated with activation in a specific brain region during moral judgment. This brain region, the right temporo-parietal junction, has been previously implicated in reasoning about other people's thoughts, beliefs, and intentions in moral and non-moral contexts.

    The fate of fluoride in a simulated accidental release into an experimental pond was observed for 30 days in Grenoble, France. The components investigated were water, sediments, plants, algae, molluscs, and fish. Twenty-four hours after the release, most (99.8%) of the fluoride was distributed in the physical components (water and sediments), and the biological agents contained only 0.2% of the fluoride released. Despite an exposure to hot spots of 5000 ppm at the beginning of the accidental release, no visible toxic effects were observed on the biological components such as plants, algae, molluscs, and fish. The effects of the physical components in the defluoridation showed a significant role in the control the accidental release of fluoride in the aquatic system.

    To study the trend of accidental death among children under 5 years of age. A survey on accidental death among children was performed in Guangzhou to compare the data from the national monitoring program on the deaths under five in the same period during 2001 - 2010. Data on mortality and causes of injures were adjusted by missing reports. Mortality rates on injuries were decreasing annually from 2001 to 2010. Comparing with 2001, the magnitude of the drop in mortality among the 0, 1 - 4 and under 5 year groups were 72.02%, 77.17% and 74.66% respectively, with statistically significant differences (P = 0.000). During the 10 years of observation, data showed a dropping trend (P = 0.000) of the mortalities on drowning, traffic accident, suffocation and falling, especially on drowning and suffocation. The main causes of death were suffocation in the 0 year group, drowning in the 1-2-year group, traffic accident and poisoning in the 3-year group, traffic accident and falling in the 4-year group. The accidental deaths happened in 'C area' which including Huadu, Conghua, Zengcheng, Panyu and Nansha, with the total proportion of accidental death in Guangzhou as 75.69%. The mortality of accidental deaths among children under 5 years of age in Guangzhou had been decreasing during 2001 - 2010, mainly owing to the practice of intervention programs on drowning and suffocation, suggesting the necessity of integrating the health education programs on accidental injury with the healthcare management system in children in the country, focusing on the suburban and county levels where economy was relatively undeveloped or with more floating population.

    Background. Child abuse specialists rely heavily on diagnostic neuroimaging. Objectives. Study objectives were: (1) to compare the frequencies of six specific intracranial CT abnormalities in accidental and non-accidental pediatric head trauma, and (2) to assess interobserver agreement regarding these CT findings. Materials and methods. Three pediatric radiologists blindly and independently reviewed cranial CT scans of pediatric patients who sustained closed head trauma between 1991 and 1994. All patients were less than 4 years of age. Study cases included thirty-nine (50 %) with non-accidental head trauma and thirty-nine (50 %) with accidental head trauma. Each scan was evaluated for the presence or absence of the following six intracranial findings: (1) interhemispheric falx hemorrhage, (2) subdural hemorrhage, (3) large (non-acute) extra-axial fluid, (4) basal ganglia edema, (5) posterior fossa hemorrhage, and (6) frontal-parietal shearing tear(s). Interobserver agreement was calculated as the percentage of total cases in which all reviewers agreed a specific CT finding was present or absent. Diagnosis required independent agreement by all three pediatric radiologists. The frequencies of these six intracranial CT abnormalities were compared between the two study groups by Chi-square analysis and Fisher`s exact test. Results. Interobserver agreement between radiologists was greater than 80 % for all lesions evaluated, with the exception of frontal-parietal shearing tear(s). Interhemispheric falx hemorrhage, subdural hemorrhage, large (non-acute) extra-axial fluid, and basal ganglia edema were discovered significantly more frequently in non-accidental trauma (P {<=}.05). Conclusion. Although not specific for child abuse, discovery of these intracranial CT abnormalities in young patients should prompt careful evaluation of family and injury circumstances for indicators of non-accidental trauma.

    One of the controversial management options for accidental dural puncture in pregnant patients is the conversion of labor epidural analgesia to continuous spinal analgesia by threading the epidural catheter intrathecally. No clear consensus exists on how to best prevent severe headache from occurring after accidental dural puncture. To investigate whether the intrathecal placement of an epidural catheter following accidental dural puncture impacts the incidence of postdural puncture headache (PDPH) and the subsequent need for an epidural blood patch in parturients. A retrospective chart review of accidental dural puncture was performed at Hutzel Women's Hospital in Detroit, MI, USA for the years 2002-2010. Documented cases of accidental dural punctures (N = 238) were distributed into two groups based on their management: an intrathecal catheter (ITC) group in which the epidural catheter was inserted intrathecally and a non-intrathecal catheter (non-ITC) group that received the epidural catheter inserted at different levels of lumbar interspaces. The incidence of PDPH as well as the necessity for epidural blood patch was analyzed using two-tailed Fisher's exact test. In the non-ITC group, 99 (54 %) parturients developed PDPH in comparison to 20 (37 %) in the ITC [odds ratio (OR), 1.98; 95 % confidence interval (CI), 1.06-3.69; P = 0.03]. Fifty-seven (31 %) of 182 patients in the non-ITC group required an epidural blood patch (EBP) (data for 2 patients of 184 were missing). In contrast, 7 (13 %) of parturients in the ITC group required an EBP. The incidence of EBP was calculated in parturients who actually developed headache to be 57 of 99 (57 %) in the non-ITC group versus 7 of 20 (35 %) in the ITC group (OR, 2.52; 95 % CI, 0.92-6.68; P = 0.07). The insertion of an intrathecal catheter following accidental dural puncture decreases the incidence of PDPH but not the need for epidural blood patch in parturients.

    OBJECTIVES—To investigate outcome, management, and prevention in Munchausen syndrome by proxy, non-accidental poisoning, and non-accidental suffocation.
DESIGN—Ascertainment through British Paediatric Surveillance Unit and questionnaires to responding paediatricians.
SETTING—The UK and Republic of Ireland, September 1992 to August 1994.
SUBJECTS—Children under 14 years diagnosed with the above.
MAIN OUTCOME MEASURES—Placement and child protection measures for victims and siblings; morbidity and reabuse rates for victims; abuse of siblings; prosecution of perpetrators.
RESULTS—Outcome data for 119 with median follow up of 24 months (range 12 to 44 months). No previously diagnosed factitious disease was found to have been caused by genuine disease. Forty six children were allowed home without conditions at follow up. Children who had suffered from suffocation, non-accidental poisoning, direct harm, and those under 5 years were less likely to go home.
 Twenty seven (24%) children still had symptoms or signs as a result of the abuse at follow up; 108/120 were originally on a child protection register and 35/111 at follow up. Twenty nine per cent (34/118) of the perpetrators had been prosecuted and most convicted; 17% of the milder cases of Munchausen syndrome by proxy allowed home were reabused. Evidence in siblings suggests that in 50% of families with a suffocated child and 40% with non-accidental poisoning there would be further abuse, some fatal.
CONCLUSIONS—This type of abuse is severe with high mortality, morbidity, family disruption, reabuse, and harm to siblings. A very cautious approach for child protection with reintroduction to home only if circumstances are especially favourable is advised. Paediatric follow up by an expert in child protection should also occur.

    Separation of the endodontic instrument within the root canal system and sharp injuries to the dentist is not an uncommon event in endodontic practice. Although root canal instruments can fracture at any stage of endodontic treatment, its fracture within the dentist's hand is a very rare event. An unusual case of accidental separation and lodgment of rotary endodontic file in the dentist's thumb is presented along with its management. A 33-year-old dentist reported with an accidental lodgment of rotary endodontic file into his thumb. The fractured instrument was removed successfully by a surgeon. The present case describes a rare event of occupational risk in endodontic practice.

    Foreign body oesophageal obstruction is a medical emergency. It may be accidental, particularly in children, or deliberate, for example with suicide attempts. We present two cases illustrating accidental oesophageal foreign body impaction occurring after consumption of food that had been heated in a plastic container in a microwave oven, then cut and eaten directly from the softened container. To date, we are not aware of any similar reports. In view of potential complications, care needs to be taken when food is eaten directly from plastic takeaway containers.

    The fundamental mechanism of the bound states in the continuum is the full destructive interference of two resonances when two eigenlevels of the closed system are crossing. There is, however, a wide class of quantum chaotic systems which display only avoided crossings of eigenlevels. As an example of such a system we consider the Sinai billiard coupled with two semi-infinite waveguides. We show that notwithstanding the absence of degeneracy bound states in the continuum occur due to accidental decoupling of the eigenstates of the billiard from the waveguides. - Highlights: • Bound states in the continuum in open chaotic billiards occur to accidental vanishing of coupling of eigenstate of billiard with waveguides.

    To assess the impact of heat waves on non-accidental deaths, and to investigate the influencing factors for deaths caused by heat waves in Jinan, China. Daily death data and meteorological data for summer days with or without heat waves in Jinan from 2012 to 2014 were collected, and a cross-over analysis was conducted to evaluate the influence of heat waves on non-accidental deaths and deaths caused by other reasons. The univariate and multivariate logistic regression models were used to investigate the influencing factors for deaths caused by heat waves. The risks of non-accidental deaths and deaths caused by circulation system diseases during the days with heat waves were 1.82 times(95% CI: 1.47~2.36) and 1.53 times(95% CI: 1.14~2.07) those during the days without heat waves. The multivariate logistic regression analysis showed that old age(≥75 years)(OR=1.184, 95% CI: 1.068~1.313), low educational level(OR=1.187, 95% CI: 1.064~1.324), and deaths outside hospital(OR=1.105, 95% CI: 1.009~1.210) were associated with the high risk of deaths during the days with heat waves. Heat waves significantly increase the risk of non-accidental deaths and deaths caused by circulation system diseases in Jinan, and the deaths during the days with heat waves are related to age, educational level, and place of death.

    Full Text Available Abstract Background The elderly are vulnerable to cold and prone to accidental hypothermia, both because of environmental and endogenous factors. The incidence of severe accidental hypothermia among the elderly is poorly described, but many cases probably go unrecorded. Going through literature one finds few publications on severe hypothermia among the elderly, and, to our knowledge, nothing about extracorporeal re-warming of geriatric hypothermia victims. Case presentation We present a case were a 95 year-old man with severe accidental hypothermia and circulatory arrest was brought to our hospital under on-going CPR, and was successfully resuscitated with extracorporeal circulation. He was discharged to his home without physical sequelae a few weeks later. Conclusion The decision whether or not to continue resuscitation of a nonagenarian can be difficult in many respects. Knowing that resuscitation with extracorporeal circulation is resource intensive may complicate the discussion. In light of our experience with this case we discuss medical and ethical aspects of modern treatment of severe accidental hypothermia.

    Australia's farmers constitute a heterogeneous group within the rural population. This literature review incorporates four broad areas: an understanding of farming communities, families and individuals and the contexts in which they live and work; an exploration of the challenges to morbidity and mortality that these communities face; a description of the patterns of suicide and accidental death in farming communities; and an outline of what is missing from the current body of research. Recommendations will be made on how these gaps may be addressed. In developing this comprehensive literature review, a snowballing and saturation approach was adopted. Initial search terms included suicid*, farm*, accident*, fatal*, death, sudden death, rural OR remote, Australia and NOT Australia. Databases searched included SCOPUS, PubMed, Proquest and SafetyLit; research from 1995 onwards was examined for relevance. Earlier seminal texts were also included. Reference lists of retrieved articles were searched and citations explored for further relevant research material. The primary focus was on Australian peer-reviewed research with supplementary grey literature. International material was used as examples. The literature variously describes farmers as members of both rural farming communities and farming families, and as individuals within an occupational classification. Within each of these classifications, there is evidence of the cumulative impact of a multiplicity of social, geographical and psychological factors relating to work, living and social arrangements that impact the health and wellbeing of Australia's farmers and their families, particularly accidental death and suicide. Research consistently demonstrates traumatic death to be at a greater rate than in the general Australian population, with reductions found more recently in some modes of farming-related accidental death. Patterns of accidental death and suicide are commonly linked to the changing shape of

    In the case of accidental release of hazardous gases in the atmosphere, the emergency responders need a reliable and fast tool to assess the possible consequences and apply the optimal countermeasures. A number of models for the prediction and simulation of hazard areas affected by accidental releases of toxic gases are available worldwide. Modelling accidental releases may be required for a variety of reasons: for analyzing different accidental toxic release scenarios ("worst-case scenarios"), for preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management (e.g. in the frame of the SEVESO directive). Depending on the demand and the particular purposes, the choice of the appropriate model is up to the authorities. The one year project was funded by the Austrian Science and research liaison Office (ASO, www.aso.zsi.at) as a part of the program: Research Cooperation and Networking between Austria, the public higher education institutions in Kosovo and South Eastern Europe. The project was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG, http://www.zamg.ac.at) in cooperation with the University of Prishtina (Kosovo, www.uni-pr.edu and the National Institute of meteorology and Hydrology (NIHM Bulgaria, www.meteo.bg). One of the main purposes of the project was to provide the both partners with basic knowledge in modelling with accidental release of toxic gases, based on the practical experience of the meteorologists from the ZAMG in the area. This knowledge can be used as scientific response to society driven current or upcoming problems especially in Kosovo. The activities involved know-how transfer on European standards and practice among the project partners, as well as joint efforts to adapt and disseminate the scientific methods and results in Kosovo. Within the project, the partners from Kosovo and Bulgaria were introduced to the atmospheric dispersion model (ALOHA - Areal

    Accidental hanging is rare across all age groups, and it is even rarer in the adult population except in autoerotic asphyxia. Few cases have been reported in the literature, which describe unusual patterns of accidental hanging. This article focuses on an unusual pattern of accidental hanging of a 25-year-old man, who was in a state of morphine-induced central nervous system depression and found dead in a sitting position with the collar of his T-shirt hanging off a jutting-out root of a tree. The hanged collar acted as a ligature compressing the neck.

    Accidental marine oil spill pollution can result in severe environmental, ecological, economic and other consequences. This paper discussed the model of Marine Oil Spill Risk Mapping (MOSRM), which was constructed as follows: (1) proposing a marine oil spill risk system based on the typical marine oil spill pollution accidents and prevailing risk theories; (2) identifying suitable indexes that are supported by quantitative sub-indexes; (3) constructing the risk measuring models according to the actual interactions between the factors in the risk system; and (4) assessing marine oil spill risk on coastal city scale with GIS to map the overall risk. The case study of accidental marine oil spill pollution in the coastal area of Dalian, China was used to demonstrate the effectiveness of the model. The coastal areas of Dalian were divided into three zones with risk degrees of high, medium, and low. And detailed countermeasures were proposed for specific risk zones.

    2017-09-01

    Full Text Available Accidental tooth avulsion is a grievous injury and common among the children. Management of avulsed tooth within alveolar socket by reimplantation becomes a challenge for the clinician due to extraoral time and media of transportation. Although the long-term prognosis of reimplantation is poor, the time during which the tooth remain within the arch will guide the development of alveolar bone completely. Moreover, reimplantation will maintain anatomical, functional and esthetic rehabilitation of the patient. In this case report, we present a case of accidental avulsion where teeth were gently rinsed of any debris and placed in normal saline during the examination and preparation of the reimplantation sockets. The teeth were then reimplanted, functionally splinted followed by endodontical treatment. After 12 months follow-up the periodontal space was healed perfectly without any resorption or ankylosis.

  5. Accidental Versus Operational Oil Spills from Shipping in the Baltic Sea: Risk Governance and Management Strategies

    2011-03-15

    Marine governance of oil transportation is complex. Due to difficulties in effectively monitoring procedures on vessels en voyage, incentives to save costs by not following established regulations on issues such as cleaning of tanks, crew size, and safe navigation may be substantial. The issue of problem structure is placed in focus, that is, to what degree the specific characteristics and complexity of intentional versus accidental oil spill risks affect institutional responses. It is shown that whereas the risk of accidental oil spills primarily has been met by technical requirements on the vessels in combination with Port State control, attempts have been made to curb intentional pollution by for example increased surveillance and smart governance mechanisms such as the No-Special- Fee system. It is suggested that environmental safety could be improved by increased use of smart governance mechanisms tightly adapted to key actors' incentives to alter behavior in preferable directions

    Full Text Available Acute toxicity is a frequent but avoidable cause of morbidity and mortality in children especially in developing countries, including India. Present study assesses their pattern with relation to different age groupings. This retrospective study was conducted among all hospitalised paediatric victims of acute accidental poisoning at the King George Medical University; Lucknow during 2010 -11. Their history, baseline characteristics, clinical course and outcome was studied. Most children were male of less than three years with 4% overall mortality. Kerosene oil was implicated in most cases. Childhood poisoning is commonest during 1-3 years with a male preponderance. Household poisons; especially kerosene oil was responsible for most cases which was consumed accidentally. Parents must be educated and warned to keep these toxic ingredients safely in suitable containers and out of reach of their beloved children.

  8. Photonic crystal surface-emitting lasers enabled by an accidental Dirac point

    Science.gov (United States)

    Chua, Song Liang; Lu, Ling; Soljacic, Marin

    2014-12-02

    A photonic-crystal surface-emitting laser (PCSEL) includes a gain medium electromagnetically coupled to a photonic crystal whose energy band structure exhibits a Dirac cone of linear dispersion at the center of the photonic crystal's Brillouin zone. This Dirac cone's vertex is called a Dirac point; because it is at the Brillouin zone center, it is called an accidental Dirac point. Tuning the photonic crystal's band structure (e.g., by changing the photonic crystal's dimensions or refractive index) to exhibit an accidental Dirac point increases the photonic crystal's mode spacing by orders of magnitudes and reduces or eliminates the photonic crystal's distributed in-plane feedback. Thus, the photonic crystal can act as a resonator that supports single-mode output from the PCSEL over a larger area than is possible with conventional PCSELs, which have quadratic band edge dispersion. Because output power generally scales with output area, this increase in output area results in higher possible output powers.

    Emergency room (ER) visits for accidental casualties, according to the International Classification of Deceases 10th Revision Chapters 19 and 20, include injury, poisoning, and external causes (IPEC). Annual distribution of 187,008 ER visits that took place between 2009 and 2011 in Beijing, China displayed regularity rather than random characteristics. The annual cycle from the Fourier series fitting of the number of ER visits was found to explain 63.2% of its total variance. In this study, the possible effect and regulation of meteorological conditions on these ER visits are investigated through the use of correlation analysis, as well as statistical modeling by using the Distributed Lag Non-linear Model and Generalized Additive Model. Correlation analysis indicated that meteorological variables that positively correlated with temperature have a positive relationship with the number of ER visits, and vice versa. The temperature metrics of maximum, minimum, and mean temperatures were found to have similar overall impacts, including both the direct impact on human mental/physical conditions and indirect impact on human behavior. The lag analysis indicated that the overall impacts of temperatures higher than the 50th percentile on ER visits occur immediately, whereas low temperatures show protective effects in the first few days. Accidental casualties happen more frequently on warm days when the mean temperature is higher than 14 °C than on cold days. Mean temperatures of around 26 °C result in the greatest possibility of ER visits for accidental casualties. In addition, males were found to face a higher risk of accidental casualties than females at high temperatures. Therefore, the IPEC-classified ER visits are not pure accidents; instead, they are associated closely with meteorological conditions, especially temperature.

    The field of non-accidental injury (NAI) has been the subject of a number of theories and hypotheses of variable merit. Concerning injuries that occur within the intracranial compartment, much research has been undertaken to investigate the cause of SDH and parenchymal brain injury. Much, however, remains contentious, particularly regarding the medicolegal aspects of suspected child abuse. Issues that present the greatest challenges will be addressed. (orig.)

    Full Text Available The purpose of this paper is to report a salvage maneuver for accidental coverage of both renal arteries during endovascular aneurysm repair (EVAR of an infrarenal abdominal aortic aneurysm (AAA. A 72-year-old female with a 6 cm infrarenal abdominal aortic aneurysm was treated by endovascular means with a standard bifurcated graft. Upon completing an angiogram, both renal arteries were found to be accidentally occluded. Through a left percutaneous brachial approach, the right renal artery was catheterized and a chimney stent was deployed; however this was not possible for the left renal artery. A retroperitoneal surgical approach was therefore carried out with a retrograde chimney stent implanted to restore blood flow. After three months, both renal arteries were patent and renal function was not different from the baseline. Both endovascular with percutaneous access via the brachial artery and open retroperitoneal approaches with retrograde catheterization are feasible rescue techniques to recanalize the accidentally occluded renal arteries during EVAR.

    Panaeolina foenisecii is one of the most common and widely distributed lawn mushrooms in Europe and North America, and frequently involved in accidental mushroom ingestion, mainly in children. Nevertheless, there is contradictory information regarding the toxicity profile of P. foenisecii in the literature. Objective of the study was to assess clinical effects with particular attention on psychoactive properties of P. foenisecii in case of accidental oral exposure. This observational case series is based on prospectively collected data on mushroom poisoning using a structured data collection form, and it was performed in seven poisons centres in Germany and Switzerland. Inclusion criteria were accidental ingestion of at least one cap of P. foenisecii identified by a mycologist, and a follow up of at least 4 hours. Nineteen cases met all inclusion criteria, and only children were involved with a mean age of 3 years. They ingested 1-2 mushrooms in 14 cases and 3-5 mushrooms in five cases. Three patients received a single dose of activated charcoal. Sixteen out of 19 cases did not develop any symptoms, 2/19 complained of minor abdominal discomfort. One child was temporarily mildly hyperactive, and this was the only patient observed in a hospital for 12 hours. None of the children showed signs of hallucinations. This multicentre study demonstrates that the typically small amounts of P. foenisecii ingested by children probably do not lead to clinically significant symptoms.

    It is known from experimental studies that antigenic potency and the concentration of antigen determine whether exposure to an antigen will result in sensitization. A single accidental exposure to concentrated antigen may therefore induce primary sensitization. The purpose of this report was to collect clinical cases in which a single exposure had resulted in contact dermatitis suspected to be allergic. Only patients without previous relevant skin symptoms were included. Patch testing was used to demonstrate sensitization. 6 patients developed occupational allergic contact dermatitis from accidental exposure. Patch testing revealed allergy to diglycidylether of bisphenol A epoxy resin, polyfunctional aziridine hardener, methyl acrylate, phenol-formaldehyde resin, and methylchloroisothiazolinone/methylisothiazolinone (Kathon LX), respectively. Furthermore, 2 patients developed allergic contact dermatitis from their first exposure to tear gas chemicals, namely omega-chloroacetophenone and ortho-chlorobenzylidene malonitrile. A single exposure can therefore induce both sensitization and subsequent allergic contact dermatitis without further exposure. The allergens described must be considered strong allergens. The skin should immediately be cleaned if an accidental splash with such an allergen has taken place.

    Patterns of accidental poisoning in children are changing dramatically. A five year population study (1977-81) was undertaken in urban children from Brisbane (population 1 000 000). A total of 2098 children were poisoned during this period with only one fatality, which represents a dramatic reduction in mortality. Over the past 15 years (1968-82) 13 children have died from accidental poisoning from this population, and two were murdered with drugs. A study of secular trends has indicated that peak incidence occurred in 1979, and the rate has been falling progressively since. The current age corrected rate of poisoning is 393 per 100 000 children per year (0-5 year olds). The rank order of poisons, drugs, and chemicals causing hospital admission and death is: petroleum distillates 13%; antihistamines 9%; benzodiazepines 9%; bleach and detergents 7%; and aspirin 6%. The ratio of fatalities to ingestions requiring hospital admission was calculated to give an index of a practical danger of noxious agents to which children are currently exposed and the rank order is: cardiotoxic drugs, one fatality to 25 ingestions; tricyclic antidepressants, one to 44; sympathomimetic drugs, one to 54; caustic soda, one to 68; aspirin, one fatality to 350 ingestions. Accidental poisoning of children leading to death has been reduced because patterns of drug prescriptions have changed, packaging of dangerous drugs has been made safer, and substances such as kerosene have been coloured blue.

    Full Text Available The development of a conceptual design of an industrial-scale transmutation facility (EFIT of several 100 MW thermal power based on accelerator-driven system (ADS is addressed in the frame of the European EUROTRANS Integral Project. In normal operation, the core power of EFIT reactor is removed through steam generators by four secondary loops fed by water. A safety-related decay heat removal (DHR system provided with four independent inherently safe loops is installed in the primary vessel to remove the decay heat by natural convection circulation under accidental conditions which are caused by a loss-of-heat sink (LOHS. In order to confirm the adequacy of the adopted solution for decay heat removal in accidental conditions, some multi-D analyses have been carried out with the SIMMER-III code. The results of the SIMMER-III code have been then used to support the RELAP5 1D representation of the natural circulation flow paths in the reactor vessel. Finally, the thermal-hydraulic RELAP5 code has been employed for the analysis of LOHS accidental scenarios.

    Humeral fracture in a non-ambulant infant younger than 1 year is suspicious for a non-accidental injury unless there is a credible accidental explanation. A previously unrecognised accidental mechanism was described in 1996 whereby a 5-month-old infant was rolled by a 3-year-old sibling from a prone to a supine position. To investigate the widely accepted view that an infant with limited mobility cannot sustain a fracture of the humerus by his or her own actions in the absence of the intervention of an external party. We present seven cases of non-ambulant infants between 4 and 7 months of age in whom an isolated humeral fracture was the only injury present. In each case the caregiver described the fracture occurring when the child rolled over, trapping the dependent arm, without the intervention of another party. There is no proof for this mechanism in the form of an independent witness or video recording. However, we propose that this mechanism is worthy of further consideration as a rare and unusual cause for the injury. Further study is required. (orig.)

    Interest is increasing in the development of new methodologies for accidental dose assessment, exploiting the luminescence and dosimetric properties of objects and materials which can be usually found directly on exposed subjects and/or in the contaminated area. In this work, several types of ceramics employed for dental prosthetics restoration, including both innovative materials used as sub-frames for the construction of the inner part of dental crowns (core), and conventional porcelains used for the fabrication of the external layer (veneer), were investigated with regard to their thermally and optically stimulated luminescence (TSL and OSL respectively) properties, in view of their potential application in accidental dosimetry. The sensitivity to ionizing radiation proved to strongly depend on the type and brand of ceramic, with minimum detectable dose ranging from few mGy up to several tens of mGy. A linear dose-response was observed for most of the samples. However, the luminescence signals were characterised by a significant fading, which has to be taken into account for a reliable accidental dose assessment after a radiation exposure event.

  6. Infant homicide and accidental death in the United States, 1940-2005: ethics and epidemiological classification.

    Potential ethical issues can arise during the process of epidemiological classification. For example, unnatural infant deaths are classified as accidental deaths or homicides. Societal sensitivity to the physical abuse and neglect of children has increased over recent decades. This enhanced sensitivity could impact reported infant homicide rates. Infant homicide and accident mortality rates in boys and girls in the USA from 1940 to 2005 were analysed. In 1940, infant accident mortality rates were over 20 times greater than infant homicide rates in both boys and girls. After about 1980, when the ratio of infant accident mortality rates to infant homicide rates decreased to less than five, and the sum of infant accident and homicide rates became relatively constant, further decreases in infant accident mortality rates were associated with increases in reported infant homicide rates. These findings suggest that the dramatic decline of accidental infant mortality and recent increased societal sensitivity to child abuse may be related to the increased infant homicide rates observed in the USA since 1980 rather than an actual increase in societal violence directed against infants. Ethical consequences of epidemiological classification, involving the principles of beneficence, non-maleficence and justice, are suggested by observed patterns in infant accidental deaths and homicides in the USA from 1940 to 2005.

    The purpose of this study was to examine the outcomes of non-accidental trauma (NAT) patients compared to other trauma (OT) patients across the state of Florida. In addition, NAT and OT patients with a mechanism of injury of assault were further analyzed. A statewide database was reviewed from January 2010 to December 2014 for patients aged 0-18years who presented following trauma. Patients were sorted by admitting diagnosis into two groups: rule out NAT and all other diagnoses. Patients with a mechanism of assault were subanalyzed and outcomes were compared. There were 46,557 patients included. NAT patients were younger, had more severe injuries and had a higher mortality rate compared to OT patients. Assault was the mechanism of injury in 95% of NAT patients. NAT assault patients were younger, required more intensive care unit (ICU) resources, and had a higher mortality rate compared to other assault patients. Non-accidental trauma patients require more resources and have a higher mortality rate compared to accidental trauma patients, and these differences remain even when controlling for the mechanism of injury.

    Brazil is signatory of international protocols related to the visit of nuclear-powered vessels, aircraft carriers and submarines to Brazilian ports. The submarines, during their stay in Brazilian ports, inform that there is no release of radioactive material to the environment. However, the possibility of occurrence of accidents with environmental releases from PWR reactors is real. Between 1993 and 2003, 13 nuclear submarines visited Brazilian ports. This work aimed to evaluate the potential impact due to the visits of nuclear-powered ships and submarines to the port of the city of Rio de Janeiro, in relation to releases of radioactive materials to the environment, considering both routine releases and accidental situations. The models selected to perform the assessments took into account the scenarios to be simulated. Simple, but conservative methodologies were used for the evaluation of routine releases. For accidental releases, the dynamics of the materials dispersion into the environment were considered. The present study was mainly focalized on the initial phase of an accident. The doses for the crew of the Brazilian navy ships, for IRD teams performing environmental monitoring, and for the population around the Guanabara Bay, close to the points of anchorage, were assessed. The results indicated that, in normal operational conditions, no significant radiological impact due to the visit of nuclear submarines to the port of the city of Rio de Janeiro is expected, even considering the occurrence of small routine radionuclide releases. The analysis of accidental releases, however, indicated that the submarines should be located at a minimum distance of 2,5 km from inhabited areas in the coast of the Guanabara Bay. The need for environmental control and training of the teams involved in the attendance of the submarines, during the period of their visit, was also considered. The need for revising the procedures for the preoperational surveys to be performed at the

Los planes de actuación preferente (PAP han sido las principales actividades preventivas desarrolladas por las comunidades autónomas (CCAA frente a las lesiones por accidentes de trabajo (LAT en España desde 1999. El objetivo de este trabajo es evaluar la efectividad de los planes. Métodos. Fueron seleccionados 4.714.080 casos incidentes de LAT no mortales con incapacidad laboral, ocurridos entre 1994 y 2004 durante la jornada laboral producidos por causas mecánicas y por sobreesfuerzo en empresas manufactureras y de servicios no públicos. A partir de las incidencias anuales se estimó en cada CCAA el porcentaje de cambio anual y su intervalo de confianza al 95% (IC95% para el periodo anterior y posterior del inicio del PAP mediante una regresión binomial negativa. Resultados. El patrón observado siguió una tendencia ascendente en los periodos previos al inicio del PAP y descendente a continuación de la puesta en marcha de estos planes. Por ejemplo, en Aragón, donde el PAP se inició en 1999, observamos un incremento de +5,3% entre 1994-1999 frente a un descenso de -4,9% entre 2000-2004. En Baleares, que inició su PAP en 2002, la tendencia correspondiente fue de +5,4% entre 1994-2001 frente a -14% entre 2002-2004. Sin embargo, se observaron tendencias similares en Madrid (-3,9% entre 2000 y 2004 o en Galicia (-4,8% entre 2000 y 2004, donde no consta que se pusieran en marcha un PAP específico en el periodo de estudio. Conclusiones. Estos resultados no permiten atribuir a los PAP el descenso generalizado en la incidencia de las LAT no mortales a partir del 2000 en España. Posiblemente, otras acciones de carácter general, que habrían afectado a todas las CCAA por igual (incluyendo a aquéllas que no han desarrollado sus propios PAP, explicarían este descenso en la incidencia de las lesiones por accidente de trabajo seleccionadas en el presente análisis.

    To study the trend of accidental death among children under 5 years of age in Beijing. Cases of death in children under 5 years old in Beijing, during 2003-2012 were collected, to analyze the strength and trends of accidental death, main causes of accident and its epidemiological features. The overall accidental death was 8.47% of all death among children under 5 years old in Beijing during 2003-2012. During these 10 years, data showed a downward trend on the mortality rates on injuries (P children under five years of age. In 2012, the accidental death rate of children under five was 6.37/105. The 5 main causes of accidental deaths were suffocation, traffic accident, falling, poisoning and drowning, in order of size. The main causes of death were suffocation in the 0-1 year group, suffocation and traffic accident in the 1-2 year group and traffic accident in the 3-4 year group. The proportion of deaths due to traffic accident increased gradually with age. Area distribution showed that accidental deaths mainly happened in rural area (52.19%), with two main types as traffic accident and suffocation. The reduction of accidental death rate among children under 5 years old in Beijing mainly was caused by the decline of accident mortality in 1-4 year old and children in the rural areas. Our data suggested that the focus in reducing the accidental death rate among children under 5 years old in Beijing should target on the prevention of infant suffocation and traffic accidents among the 1-4 year old, with rural areas in particular.

    Accidental suffocation and strangulation in bed, a subgroup of sudden, unexpected infant deaths, is a leading mechanism of injury-related infant deaths. We explored trends and characteristics of these potentially preventable deaths. In this descriptive study, we analyzed US infant mortality data from 1984 through 2004. To explore trends in accidental suffocation and strangulation in bed and other sudden, unexpected infant deaths, we calculated cause-specific infant mortality rates and estimated proportionate mortality. Sudden, unexpected infant death was defined as a combination of all deaths attributed to accidental suffocation and strangulation in bed, sudden infant death syndrome, and unknown causes. Finally, we examined factors that were reported as contributing to these accidental suffocation and strangulation in bed deaths. Between 1984 and 2004, infant mortality rates attributed to accidental suffocation and strangulation in bed increased from 2.8 to 12.5 deaths per 100000 live births. These rates remained relatively stagnant between 1984 and 1992 and increased between 1992 and 2004; the most dramatic increase occurred between 1996 and 2004 (14% average annual increase). In contrast, total sudden, unexpected infant death rates remained stagnant between 1996 and 2004, whereas the proportion of deaths attributed to sudden infant death syndrome declined and to unknown cause increased. Black male infants Infant mortality rates attributable to accidental suffocation and strangulation in bed have quadrupled since 1984. The reason for this increase is unknown. Prevention efforts should target those at highest risk and focus on helping parents and caregivers provide safer sleep environments.

    The Fukushima nuclear accident led to the most important accidental release of artificial radionuclides into the sea. This accident has underlined the importance of being able to adequately reproduce the fate of radioactive releases and to estimate their consequences for the marine environment. For its Crisis Centre, the French Institute for Radioprotection and Nuclear Safety (IRSN) has operational tools, in order to help experts and decision makers in case of any atmospheric accidental release and terrestrial environment contamination. The on-going project aims to develop tools to manage any marine contamination of the French coastal areas. We should be able to evaluate and anticipate the marine post-accidental situation: contaminated areas localization and contamination levels, and possible consequences. Many sites has be considered as potential source terms into the sea: the Coastal Nuclear Power Plants, the La Hague reprocessing Plant, the Brest and Toulon Military Harbours as home-ports of nuclear powered vessels, and different river mouths (Rhone River, Gironde, Loire, Seine) that could be contaminated by upstream accidental release. To achieve this goal, two complementary approaches are developed: Marine sheets and a dedicated modelling tool (STERNE). - Marine sheets aim to summarize marine environment characteristics for the different sites, identify potential stakes for human protection such as aquaculture areas, beaches, or industrial water intakes, and ecological stakes. Whenever possible, a local climatology (main currents depending on meteorological or tide conditions) that could be a support to first environmental measurement strategy is proposed. A list of available local contacts for any operational management is also provided. - The modelling tool, STERNE (Simulation du Transport et du transfert d'Elements Radioactifs dans l'environNEment marin), must predict radionuclide dispersion and contamination of water, marine species and sediments

    An accidental case of aconite intoxication occurred after a patient took a therapeutic dose of Kampo herbal medicine containing Aconiti tuber, Uzu but had used the wrong decoction procedure. The poisoning was likely caused by an increased level of Aconitum alkaloids in the decoction; the patient developed aconite intoxication due to incomplete decoction. Aconitum alkaloid levels in the leftover solution which the patient had drunk and in the decoction extracted from 3g Uzu were determined. It was found that decoction makes the medicine safer to drink. Older individuals, especially those with dementia, have a higher risk of aconite poisoning because they sometimes do not boil the medicine appropriately.

    Pilipchuk, A. S.; Sadreev, A. F.

    2017-02-01

    The fundamental mechanism of the bound states in the continuum is the full destructive interference of two resonances when two eigenlevels of the closed system are crossing. There is, however, a wide class of quantum chaotic systems which display only avoided crossings of eigenlevels. As an example of such a system we consider the Sinai billiard coupled with two semi-infinite waveguides. We show that notwithstanding the absence of degeneracy bound states in the continuum occur due to accidental decoupling of the eigenstates of the billiard from the waveguides.

    Obtaining central venous access is a standard procedure necessary for safe anesthesia in patients undergoing surgery with extracorporeal circulation. It is well known that jugular way is safer and causes less complication than subclavian. The authors present a case of accidental left subclavian artery cannulation during left internal jugular vein catheterisation. Due to the complex character of myocardial revascularization procedure with extracorporeal circulation and specific catheter localization surgical removal was necessary. This case underline well documented high risk of internal jugular vein cannulation even in operating room condition.

    Full Text Available We present a model of radiative neutrino mass that automatically contains an accidental Z2 symmetry and thus provides a stable dark matter candidate. This allows a common framework for the origin of neutrino mass and dark matter without invoking any symmetries beyond those of the Standard Model. The model can be probed by direct-detection experiments and μ→e+γ searches, and predicts a charged scalar that can appear at the TeV scale, within reach of collider experiments.

The aim of this study was to predict return to work following serious accidental injuries. Method 121 severely injured patients were included in the study. Complete follow-up data were available for 85 patients. Two weeks post trauma (T1, patients rated their appraisal of the injury severity and their ability to cope with the injury and its job-related consequences. Time off work was assessed at one (T2 and three years (T3 post accident. The main outcome was the number of days of sick leave taken due to the accidental injury. Results The patients' appraisals a of the injury severity and b of their coping abilities regarding the accidental injury and its job-related consequences were significant predictors of the number of sick-leave days taken. Injury severity (ISS, type of accident, age and gender did not contribute significantly to the prediction. Conclusions Return to work in the long term is best predicted by the patients' own appraisal of both their injury severity and the ability to cope with the accidental injury.

    Maria Rosa Rodrigues Rissi

    Full Text Available This study aimed to analyze affective and cognitive determinants of the professional work of individuals caring for patients with HIV/AIDS, in view of the risk and/or experience of accidental exposure to blood. We drew on the theoretical-methodological references of Fishbein & Ajzen and Maslow's theory. Fifty health care workers were evaluated using an attitudes questionnaire and a needs and motivations instrument. The research verified differences between answers by health care workers who had never suffered accidents and those who had already experienced accidental exposure to blood. Health care workers did their work activities motivated by the need for self-fulfillment and valued their own performance when they were able to meet the patients' emotional needs. Among health professionals who had never experienced accidental exposure to blood, the predominant beliefs was that patients feel remorse over having expose themselves to HIV. Accidental exposure to blood raises difficulties in personal life. Technical aspects are also associated with the possibility of accidental exposure to blood.

    Cannabis intoxication in toddlers is rare and mostly accidental. Our objectives were to focus on the characteristics and management of children under the age of 6 years who were admitted to our emergency department with cannabis poisoning reported as accidental by parents, and to point out the need to consider accidental cannabis ingestions as an indicator of neglect. The medical records of children hospitalized for cannabis poisoning in a pediatric emergency department from January 2007 to November 2012 were retrospectively evaluated. Data collected included age, sex, drug ingested, source of drug, intentional versus accidental ingestion, pediatric intensive care unit or hospital admission, treatment and length of hospital stay, toxicology results, and rate of child protectives services referral. Twelve toddlers (4 boys and 8 girls; mean age, 16.6 months) were included. All had ingested cannabis. Their parents reported the ingestion. Seven children experienced drowsiness or hypotonia. Three children were given activated charcoal. Blood screening for cannabinoids, performed in 2 cases, was negative in both, and urine samples were positive in 7 children (70%). All children had favorable outcomes after being hospitalized from 2 to 48 hours. Nine children were referred to social services for further assessment before discharge. Cannabis intoxication in children should be reported to child protection services with the aim of prevention, to detect situations of neglect and at-risk families. Legal action against the parents may be considered. Accidental intoxication and caring parents should be no exception to this rule.

    The recent expansion of biocontainment laboratory capacity in the United States has drawn attention to the possibility of occupational exposures to BSL-3 and -4 agents and has prompted a reassessment of medical management procedures and facilities to deal with these contingencies. A workshop hosted by the National Interagency Biodefense Campus was held in October 2007 and was attended by representatives of all existing and planned BSL-4 research facilities in the U.S. and Canada. This report summarizes important points of discussion and recommendations for future coordinated action, including guidelines for the engineering and operational controls appropriate for a hospital care and isolation unit. Recommendations pertained to initial management of exposures (ie, immediate treatment of penetrating injuries, reporting of exposures, initial evaluation, and triage). Isolation and medical care in a referral hospital (including minimum standards for isolation units), staff recruitment and training, and community outreach also were addressed. Workshop participants agreed that any unit designated for the isolation and treatment of laboratory employees accidentally infected with a BSL-3 or -4 pathogen should be designed to maximize the efficacy of patient care while minimizing the risk of transmission of infection. Further, participants concurred that there is no medically based rationale for building care and isolation units to standards approximating a BSL-4 laboratory. Instead, laboratory workers accidentally exposed to pathogens should be cared for in hospital isolation suites staffed by highly trained professionals following strict infection control procedures.

    To examine trends in codeine-related mortality rates in Australia, and the clinical and toxicological characteristics of codeine-related deaths. Analysis of prospectively collected data from the National Coronial Information System on deaths where codeine toxicity was determined to be an underlying or contributory cause of death. The study period was 2000-2013. Population-adjusted numbers (per million persons) of (1) codeine-related deaths, classified by intent (accidental or intentional); and (2) heroin- and Schedule 8 opioid-related deaths (as a comparator). The overall rate of codeine-related deaths increased from 3.5 per million in 2000 to 8.7 per million in 2009. Deaths attributed to accidental overdoses were more common (48.8%) than intentional deaths (34.7%), and their proportion increased during the study period. High rates of prior comorbid mental health (53.6%), substance use (36.1%) and chronic pain (35.8%) problems were recorded for these deaths. For every two Schedule 8 opioid-related deaths in 2009, there was one codeine-related death. Most codeine-related deaths (83.7%) were the result of multiple drug toxicity. Codeine-related deaths (with and without other drug toxicity) are increasing as the consumption of codeine-based products increases. Educational messages are needed to better inform the public about the potential harms of chronic codeine use, especially in the context of polypharmacy.

Las tendencias sugieren que las tasas de mortalidad por causas externas para los viejos no acompañaron los alarmantes niveles de los adultos. Para los añosos, los niveles ascendieron ligeramente en el país para los hombres y disminuyó para las mujeres, y fueron los accidentes de vehículos y caídas accidentales las causas más importantes. El análisis multivariado apunta marcadas variaciones geográficas en las tendencias de las tasas de mortalidad que reflejan diferencias sociales y económicas entre los estados.

    The purpose of this study was to examine US accidental poisoning death rates by demographic and geographic factors from 1979 to 2014, including High Intensity Drug Trafficking Areas. Crude and age-adjusted death rates were formed for age group, race, sex, and county for accidental poisonings (ICD 9th revision: E850-E869; ICD 10th revision: X40-X49) from 1979 to 2014 using the Mortality and Population Data System housed at the University of Pittsburgh. Rate ratios were calculated comparing rates from 2014 to 1979, overall, by sex, age group, race, and county. Joinpoint regression detected changes in trends and calculated the average annual percentage change (AAPC) as a summary measure of trend. Drug poisoning mortality rates have risen an average of 6% per year since 1979. Increases are occurring in all ages 15+, and in all race-sex groups. HIDTA counties with the highest mortality rates were in Appalachia and New Mexico. Many of the HIDTA border counties had lower rates of mortality. The drug poisoning mortality epidemic is continuing to grow. While HIDTA resources are appropriately targeted at many areas in the US most affected, rates are also rapidly rising in some non-HIDTA areas. Copyright © 2016 Elsevier Inc. All rights reserved.

    Paravertebral block (PVB) is the technique of injecting a local anesthetic solution alongside the vertebral column, close to where the spinal nerves emerge, resulting in unilateral somatic and sympathetic nerve blockade. Here is reported a fatal case involving a 60-year-old woman with spondylitis arthropathy, who developed cardiac and respiratory arrest 40min after receiving an accidental subarachnoid injection (L5-S1 bilaterally) of depomedrol lidocaine and levobupivacaine. A complete autopsy including histological and toxicological analyses was performed in order to establish the cause of death. Liquid/liquid extraction (LLE) and GC-MS analysis were performed according to a previously published method. Lidocaine and bupivacaine were detected both in blood, at concentrations of 14.8mg/L and 13.3mg/L respectively, and in cerebrospinal fluid (CSF) at concentrations of 287.1mg/L and 464.2mg/L respectively. Both lidocaine and bupivacaine were also detected in the urine. The toxicological findings along with the autopsy allowed us to establish that the accidental subarachnoid injection of lidocaine and levobupivacaine had led to a progressive hypotension and normovolaemic shock caused by a severe ganglionic block, determining the patient's death.

    We study the effect of hydrostatic pressure on the magnetotransport properties of zirconium pentatelluride. The magnitude of resistivity anomaly gets enhanced with increasing pressure, but the transition temperature T* is insensitive to it up to 2.5 GPa. In the case of H ∥b , the quasilinear magnetoresistance decreases drastically from 3300% (9 T) at ambient pressure to 230% (9 T) at 2.5 GPa. Besides, the change of the quantum oscillation phase from topological nontrivial to trivial is revealed around 2 GPa. Both demonstrate that the pressure breaks the accidental Dirac node in ZrTe5. For H ∥c , in contrast, subtle changes can be seen in the magnetoresistance and quantum oscillations. In the presence of pressure, ZrTe5 evolves from a highly anisotropic to a nearly isotropic electronic system, which accompanies the disruption of the accidental Dirac semimetal state. It supports the assumption that ZrTe5 is a semi-3D Dirac system with linear dispersion along two directions and a quadratic one along the third.

    To quantify the prevalence of accidental blood exposure (ABE) among interventional radiologists and contrast that with the prevalence of patients with hepatitis C virus (HCV) undergoing interventional radiology procedures. A multicenter epidemiologic study was conducted in radiology wards in France. The risk of ABE to radiologists was assessed based on personal interviews that determined the frequency and type of ABE and the use of standard protective barriers. Patients who underwent invasive procedures underwent prospective sampling for HCV serologic analysis. HCV viremia was measured in patients who tested positive for HCV. Of the 77 radiologists who participated in 11 interventional radiology wards, 44% reported at least one incident of mucous membrane blood exposure and 52% reported at least one percutaneous injury since the beginning of their occupational activity. Compliance with standard precautions was poor, especially for the use of protective clothes and safety material. Overall, 91 of 944 treated patients (9.7%) tested positive for HCV during the study period, of whom 90.1% had positive viremia results, demonstrating a high potential for contamination through blood contacts. The probability of HCV transmission from contact with contaminated blood after percutaneous injury ranged from 0.013 to 0.030; the high frequency of accidental blood exposure and high percentage of patients with HCV could generate a risk of exposure to HCV for radiologists who perform invasive procedures with frequent blood contact. The need to reinforce compliance with standard hygiene precautions is becoming crucial for medical and technical personnel working in these wards.

    Bivalve molluscan shellfish such as oysters may be contaminated by human pathogens. Currently, the primary pathogens associated with shellfish-related outbreaks are noroviruses. This study was conducted to improve understanding of oyster bioaccumulation when oysters were exposed to daily contamination or one accidental contamination event, i.e., different modes of contamination. Oysters were contaminated with two representative strains of norovirus (GI.1 and GII.3) and then analyzed with real-time reverse transcription PCR. Exposure to a repeated virus dose for 9 days (mimicking a growing area subjected to frequent sewage contamination) led to an additive accumulation that was not significantly different from that obtained when the same total dose of virus was added all at once (as may happen after accidental sewage discharge). Similarly, bioaccumulation tests performed with mixed strains revealed additive accumulation of both viruses. Depuration may not be efficient for eliminating viruses; therefore, to prevent contaminated shellfish from being put onto the market, continuous sanitary monitoring must be considered. All climatic events or sewage failures occurring in production areas must be recorded, because repeated low-dose exposure or abrupt events may lead to similar levels of accumulation. This study contributes to an understanding of norovirus accumulation in oysters and provides suggestions for risk management strategies.

    Highlights: • This paper presents transient CFD analyses on the cooling channels of the DEMO HCPB FW for accidental scenarios LOCA and LOFA. • In both LOCA & LOFA, the wall temperature increases quickly to an unacceptable level within seconds. • If the coolant flow rate is maintained at a half of nominal value in case of LOFA (partial LOFA), the wall temperature rises much slower, but will still leads to a damage of structure within minutes. • The simulated heat transfer coefficients were compared with empirical correlations. - Abstract: Helium Cooled Pebble Bed (HCPB) blanket concept is one of the DEMO (Demonstration Power Plant) blanket concepts running for the final DEMO design selection. In this paper, transient analyses on the cooling channels of the FW are carried out by means of CFD simulations for the selected accidental scenarios loss-of-coolant-accident (LOCA) and loss-of-flow-accident (LOFA). ANSYS-CFX is used for the simulations. The simulation results help to understand how fast the temperature of the FW can increase and what is the time window that is available until the temperature of the structural material reaches the design limit in order to be able to define a suitable protection strategy for the system. In view of later developments of the models, the heat transfer coefficients calculated with CFD are compared with the values predicted by two widely used correlations for turbulent pipe flows.

    Case report of a very serious drinking water incident putting up to 50,000 inhabitants of a town near Bonn in North Rhine-Westphalia, Germany at risk. A concentrated solution of highly alkaline water by sodium hydroxide was accidentally washed into the town's drinking water at a pumping station and increased the pH-value of the water to 12. Residents who came into contact with the contaminated water immediately had a toxic reaction. The incident was detected by complaints from customers and after that was stopped within several hours. The pipes were flushed and the customers were warned not to use the water till the all clear. After this immediate management there was an investigation and the cause of the incident was detected as an accidental release of accumulated sodium hydroxide (NaOH) solution. The lack of a network alarm system and the automatic cut-off mechanisms as deficiencies in the design of the station were rectified by the water company immediately after the incident.

    Accidental water basin pollution seriously threatens human health and ecological security, but rapid, effective methods for evaluating this threat are lacking. This paper aims to develop a risk evaluation method for basin accidents by coupling the risk source with sensitive targets to evaluate the zone accident risk levels of basins and prevent the accidental environmental pollution of water. This method incorporates the interplay between risk sources and sensitive targets by evaluating the zone risk levels of water environments from different sources, effectiveness of the risk source control mechanisms, vulnerability of sensitive targets and spatial and temporal relationships between these sources and targets. Using the Three Gorges Reservoir region as an example, a risk system for water basin pollution incidents consisting of a risk indicator quantification system, a risk zoning method and a verification method for the zoning results is developed and implemented. The results were verified in a field investigation, which showed that the risk zoning model provides rapid, effective and reliable zoning results. This research method could serve as a theoretical reference and technological support for evaluating water basin accident risks. Furthermore, the results are useful for evaluating and protecting the aquatic environments in the Three Gorges Reservoir region.

    Full Text Available Here, authors present a review on clinical presentation and management of exposure of phosgene gas after reviewing the literature by searching with keywords phosgene exposure on Google, Cochrane, Embase and PubMed with a background of experience gained from 10 patients who were admitted to our institute after an accidental phosgene exposure in February 2011 nearby a city in India. Phosgene is a highly toxic gas, occupational workers may have accidental exposure. The gas can also be generated inadvertently during fire involving plastics and other chemicals and solvents containing chlorine, which is of concern to emergency responders. Phosgene inhalation may cause initially symptoms of respiratory tract irritation, patients feel fine thereafter, and then die of choking a day later because of build up of fluid in the lungs (delayed onset non-cardiogenic pulmonary edema. Phosgene exposure is associated with significant morbidity and mortality. Patients with a history of exposure should be admitted to the hospital for a minimum of 24 h for observation because of the potential for delayed onset respiratory failure and acute respiratory distress syndrome.

  14. Short- and long-term effects of accidental oil pollution in waters of the Nordic countries

    Energy Technology Data Exchange (ETDEWEB)

    2008-07-01

    The main objective of the present report is to support Nordic Countries with environmental impact assessments of accidental oil spills in Nordic areas, in the work to control and reduce the cause of these effects. The Nordic Seas have specific habitats with specialised key-species which have different sensitivities to oil spills. This report studies the short- and long-term effects of accidental oil spills in these habitats. Birds and questionably marine mammals are under greatest threat from both short- and long-term effects. The plankton community will also be affected, but is quickly re-established. The impact on pelagic fish is negligible in short term but not in a long time perspective, and benthic fauna will be practically unaffected by short-term effects. They can however in a long-term suffer significantly from settled oil slicks. In the foreseeable future the number of minor oil spills is likely to increase, as will the risk for major accidents. Thus there is a strong need for mapping and identifying important and sensitive species and habitat. With senistivity atlases for the Nordic seas and coastal areas precautious measures can be implemented to reduce the magnitude of the short- and long term impact from an oil spill. (au)

    2017-01-01

    Full Text Available Integrated Deterministic and Probabilistic Safety Analysis (IDPSA of dynamic systems calls for the development of efficient methods for accidental scenarios generation. The necessary consideration of failure events timing and sequencing along the scenarios requires the number of scenarios to be generated to increase with respect to conventional PSA. Consequently, their postprocessing for retrieving safety relevant information regarding the system behavior is challenged because of the large amount of generated scenarios that makes the computational cost for scenario postprocessing enormous and the retrieved information difficult to interpret. In the context of IDPSA, the interpretation consists in the classification of the generated scenarios as safe, failed, Near Misses (NMs, and Prime Implicants (PIs. To address this issue, in this paper we propose the use of an ensemble of Semi-Supervised Self-Organizing Maps (SSSOMs whose outcomes are combined by a locally weighted aggregation according to two strategies: a locally weighted aggregation and a decision tree based aggregation. In the former, we resort to the Local Fusion (LF principle for accounting the classification reliability of the different SSSOM classifiers, whereas in the latter we build a classification scheme to select the appropriate classifier (or ensemble of classifiers, for the type of scenario to be classified. The two strategies are applied for the postprocessing of the accidental scenarios of a dynamic U-Tube Steam Generator (UTSG.

    Non-Accidental Trauma (NAT) is a significant cause of childhood morbidity and mortality, causing 50% of trauma-related deaths at our institution. Our purpose was to evaluate the necessity of primary surgical evaluation and admission to the trauma service for children presenting with NAT. We reviewed all NAT patients from 2007-2011. Injury types, demographic data, and hospitalization information were collected. Comparisons to accidental trauma (AT) patients were made using Wilcoxon rank sum and Student's t tests. We identified 267 NAT patients presenting with 473 acute injuries. Injuries in NAT patients were more severe than in AT patients, and Injury Severity Scores, ICU admission rates, and mortality were all significantly (pMultiple areas of injury were seen in patients with closed head injuries (72%), extremity fractures (51%), rib fractures (82%), and abdominal/thoracic trauma (80%). Despite these complex injury patterns, only 56% received surgical consults, resulting in potential delays in diagnosis, as 24% of abdominal CT scans were obtained >12 hours after hospitalization. Given the high incidence of polytrauma in NAT patients, prompt surgical evaluation is necessary to determine the scope of injury. Admission to the trauma service and a thorough tertiary survey should be considered for all patients. Copyright © 2013 Elsevier Inc. All rights reserved.

    Datura stramonium (DS) is a hallucinogenic plant that can produce anticholinergic toxicity because of its significant concentrations of toxic alkaloids, such as atropine, hyoscyamine, and scopolamine. DS grows in both rural and urban areas in Turkey. Clinical findings of toxicity are similar to those of atropine toxicity. DS abuse is common among adolescents because of its hallucinatory effects. However, accidental DS poisoning from contaminated food is very rare. Accidental poisonings are commonly seen among children. Children are more prone to the toxic effects of atropine; ingestion of even a small amount can cause serious central nervous system symptoms. Treatment is supportive; antidote treatment is given rarely. An eight-year-old male with accidental DS poisoning who presented to the Pediatric Emergency Department with aggression, agitation, delirium, and visual hallucinations is reported.

    Corrosive acid ingestion is a rare but serious health hazard with fatal complications. Cases of suicidal and accidental acid ingestion have been documented in the scientific literature. Accidental acid poisoning due to a mistaken identity of the bottle containing sulphuric acid is a matter of grave concern especially in a household set-up. We hereby report a fatal case of accidental sulphuric acid ingestion in an adult, who unsuspectingly swallowed about 50 ml of 'toilet-cleaner' at his residence. The bottle containing the acid was recently purchased from a local vendor and placed with water bottles in the kitchen. The autopsy and toxicological findings of this case are discussed in this paper with discussion of medico-legal issues on the sale and use of such corrosive acids in illegal bottles and its subsequent health hazards in India. © The Author(s) 2016.

    2009-04-01

    Several air dispersion models are available for prediction and simulation of the hazard areas associated with accidental releases of toxic gases. The most model packages (commercial or free of charge) include a chemical database, an intuitive graphical user interface (GUI) and automated graphical output for effective presentation of results. The models are designed especially for analyzing different accidental toxic release scenarios ("worst-case scenarios"), preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management. Uncertainties in the meteorological input together with incorrect estimates of the source play a critical role for the model results. The research project RETOMOD (reference scenarios calculations for toxic gas releases - model systems and their utility for the fire brigade) was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG) in cooperation with the Vienna fire brigade, OMV Refining & Marketing GmbH and Synex Ries & Greßlehner GmbH. RETOMOD was funded by the KIRAS safety research program at the Austrian Ministry of Transport, Innovation and Technology (www.kiras.at). The main tasks of this project were 1. Sensitivity study and optimization of the meteorological input for modeling of the hazard areas (human exposure) during the accidental toxic releases. 2. Comparison of several model packages (based on reference scenarios) in order to estimate the utility for the fire brigades. This presentation gives a short introduction to the project and presents the results of task 1 (meteorological input). The results of task 2 are presented by Stenzel and Baumann-Stanzer in this session. For the aim of this project, the observation-based analysis and forecasting system INCA, developed in the Central Institute for Meteorology and Geodynamics (ZAMG) was used. INCA (Integrated Nowcasting through Comprehensive Analysis) data were calculated with 1 km horizontal resolution and

    Missing a fracture in a child on skeletal surveys for suspected non-accidental trauma can have devastating results. Double-read has the potential to improve fracture detection. However the yield of double-read is unknown. To determine the advantage of double-read versus single-read of radiographic skeletal surveys for suspected non-accidental trauma. The study was performed in two phases. In the first phase (April 2013 to September 2013), double-read was performed for all skeletal surveys obtained during weekday working hours. Because we had no new double-read findings in studies initially read as negative, we conducted a second phase (January 2014 to March 2014). In the second phase we limited double-reads to skeletal surveys found positive on the first read. At the end of this period, we retrospectively performed double-read for all initially negative skeletal surveys. We excluded follow-up skeletal surveys. The difference in discrepancy (new fracture or false diagnosis of a fracture) ratio between negative and positive skeletal surveys was evaluated using the Fisher exact test, and change in discrepancy ratio between the first and second study phases was evaluated using the stratified Cochran-Mantel-Haenszel test. Overall in the two phases, 178 skeletal surveys were performed in 178 children (67 girls) with mean age of 9 months (range 3 days to 3.7 years). Double-read found 16 discrepancies in 8/178 (4.5%) skeletal surveys. Seven of these studies showed additional fractures (n=15). In one study, an initial read of a skull fracture was read as a variant on the second read. There was a significant (P=0.01) difference between rate of disagreement in negative skeletal surveys (1/104, 1.0%) and positive skeletal surveys (7/74, 9.5%). No significant change in disagreement rate was demonstrated between the two phases of the study (P=0.59). Double-read of skeletal survey for suspected non-accidental trauma found false-negative fractures in a few cases and rarely found

  7. Accidental iatrogenic intoxications by cytotoxic drugs: error analysis and practical preventive strategies.

    Drug errors are quite common. Many of them become harmful only if they remain undetected, ultimately resulting in injury to the patient. Errors with cytotoxic drugs are especially dangerous because of the highly toxic potential of the drugs involved. For medico-legal reasons, only 1 case of accidental iatrogenic intoxication by cytotoxic drugs tends to be investigated at a time, because the focus is placed on individual responsibility rather than on system errors. The aim of our study was to investigate whether accidental iatrogenic intoxications by cytotoxic drugs are faults of either the individual or the system. The statistical analysis of distribution and quality of such errors, and the in-depth analysis of contributing factors delivered a rational basis for the development of practical preventive strategies. A total of 134 cases of accidental iatrogenic intoxication by a cytotoxic drug (from literature reports since 1966 identified by an electronic literature survey, as well as our own unpublished cases) underwent a systematic error analysis based on a 2-dimensional model of error generation. Incidents were classified by error characteristics and point in time of occurrence, and their distribution was statistically evaluated. The theories of error research, informatics, sensory physiology, cognitive psychology, occupational medicine and management have helped to classify and depict potential sources of error as well as reveal clues for error prevention. Monocausal errors were the exception. In the majority of cases, a confluence of unfavourable circumstances either brought about the error, or prevented its timely interception. Most cases with a fatal outcome involved erroneous drug administration. Object-inherent factors were the predominant causes. A lack of expert as well as general knowledge was a contributing element. In error detection and prevention of error sequelae, supervision and back-checking are essential. Improvement of both the individual

    Full Text Available As the result of the Chernobyl NPP accident more than 200 thousand square kilometers of the European territories were contaminated by Cs-137 in the amount of above 37 kBq/m2 (1 Ci/km2 . Belorussia, Russia and Ukraine amount up to 70% of this entire affected area. More than 600 000 people were engaged in the accidental cleanup operations, 340000 were evacuated or relocated within 1986-1991. The early stage evacuation efficacy is confirmed by the absence of acute radiation syndrome among the population and by the prevented collective dose which amounts to no less than 10 000 man/Sv. The effective measure to reduce the internal radiation dose to the population at the early accidental stage was introduction of maximum tentative permissive levels of radionuclide content in the foodstuffs.Among the identified post -accident medical consequences of the Chernobyl is the radiation syndrome found in 134 emergency cleanup workers within the first 24 hours of the accident’s development. Out of that number, 28 people died within the first four months, 19 people died before 2006. The accident’s liquidators developed radiation -induced leukemia ( the attributive risk value is 45-60% . People exposed to high radiation doses display the statistically significant 18% morbidity increase of all types of solid cancers at the doses above 150 mSv. There is the statistically significant information indicating the increased amount of thyroid cancer morbidity among those who were just children and teenagers at the time of the accident. The adverse psychological consequences are accounted for not just the fear of overexposure but also for the disturbance of the habitual lifestyle especially mindful of the forced relocation.The longterm protection measures, radionuclide decay and selfcleaning of the contaminated areas resulted in the drastic reduction of the population dose in the radioactively contaminated territories. In 2015, only in some settlements of the Briansk

  9. Urban "accidental" wetlands mediate water quality and heat exposure for homeless populations in a desert city

    In urban settings where humans interact in complex ways with ecosystems, there may be hidden or unanticipated benefits (services) or harm (disservices) conferred by the built environment. We examined interactions of a highly vulnerable population, the homeless, with urban waterways and wetlands in the desert city of Phoenix, Arizona, U.S.A. Climate change models project increases in heat, droughts, and extreme floods for the southwestern U.S. These projected changes pose a number of problems for sustainability and quality of future water supply, and the ability of human populations to mitigate heat stress and avoid fatalities. Urban wetlands that are created "accidentally" (by water pooling in abandoned areas of the landscape) have many structural (e.g., soils and hydrology) and functional (e.g., high denitrification) elements that mimic natural, unaltered aquatic systems. Accidental wetland systems in the dry bed of the Salt River, fed by storm and waste water from urban Phoenix, are located within economically depressed sections of the city, and show the potential for pollutant and heat mitigation. We used a mixed-method socio-ecological approach to examine wetland ecosystem functions and the ways in which homeless populations utilize Salt River wetlands for ecosystem services. Interviews and trash surveys indicated that homeless people are accessing and utilizing the wetlands as a source of running water, for sanitary and heat mitigation services, and for recreation and habitation. Environmental monitoring demonstrated that the wetlands can provide a reliable source of running water, nutrient and pathogen removal, heat mitigation, and privacy, but they may also pose a health risk to individuals coming in contact with the water through drinking or bathing. Whether wetlands provided a net benefit vs. harm varied according to site, season, and particular service, and several tradeoffs were identified. For example, heat is highest during the summer storm season

  14. Malignant Cerebellar Edema Subsequent to Accidental Prescription Opioid Intoxication in Children

    Directory of Open Access Journals (Sweden)

    Daniel Duran

    2017-07-01

    Full Text Available We present two recent cases of toddlers who developed malignant cerebellar edema subsequent to accidental ingestion of prescription opioids. Both children presented acute neurological decline, hydrocephalus, and tonsillar herniation requiring emergent ventricular drain placement, suboccipital craniectomy, and partial cerebellectomy. Together with several other reports, these cases suggest the existence of an uncommon yet severe syndrome of acute opioid-induced malignant cerebellar edema. We hypothesize that the condition results from a combination of primary opioid receptor-mediated changes in neuronal metabolism that are exacerbated by secondary hypoxic insult. If recognized promptly, this syndrome can be treated with emergent neurosurgical intervention with good clinical outcomes. These cases also illustrate the unintended consequences and innocent victims of the spiraling prescription opioid epidemic, which will likely increase in prevalence. Recognition of this syndrome by clinicians is thus critical.

    March 1, 1984, was the 30th anniversary of the Bravo thermonuclear test that resulted in the accidental exposure of the populations of Rongelap and Utirik atolls to radioactive fallout. The chronicling of the medical events resulting from that exposure is continued in this report, which covers the period from January 1983 through December 1984. An updated listing of all relevant publications from the Medical Department Brookhaven National Laboratory, is presented in the Reference Section. Thirty years of observation continue to show no detectable increase in mortality in the exposed population as a result of that exposure. The survival curves of the high-exposure Rongelap group, the low-exposure Utirik population, and an unexposed group of Rongelap people matched by age and sex to the exposed Rongelap group in 1957 continue to be similar. 89 refs., 2 figs., 6 tabs.

    An accidental hydrogen release in equipment enclosures may result in the presence of a detonable mixture in a confined environment. To assess the value of CFD techniques as a tool for damage assessment, numerical simulation of detonation was performed for two realistic scenarios. The first scenario starts with a pipe failure in an electrolyzer, resulting in a leak of 42 g of hydrogen. The second scenario deals with a failure in a reformer where 84 g of hydrogen is released. Dispersion patterns were first obtained from separate numerical simulation and detonative ignition was simulated by adding energy to a narrow region. Impulse values reached 600 Ns/m{sup 2} in the electrolyzer scenario while they reached 1100 Ns/m{sup 2} in the reformer. For all cases studied, the consequences are more serious in the reformer than the electrolyzer. (author)

    Exotic species have often been introduced into a new country in zoological or botanical gardens or on game and fur farms. When accidentally or deliberately released, these alien species can become invasive and have negative impacts on native plant and animal communities and human activities. This article focuses on a selection of such invasive species: principally the American mink (Neovison vison), but also the coypu (Myocastor coypus), muskrat (Ondatra zibethicus), raccoon dog (Nyctereutes procyonoides), raccoon (Procyon lotor) and African sacred ibis (Threskiornis aethiopicus). In each of these cases, the authors describe the biological characteristics and life history of the species, in relation to its invasive capacity, the origins and establishment of non-native populations, the environmental consequences and possible control measures. The main negative impacts observed are the destruction of habitat, the introduction and/or spread of pathogens and changes in the composition of native communities with consequent effects on biodiversity.

    2011-01-01

    In this paper, we examine the ways that early adolescents talked, interacted, and made references to events in their individual and collective lives during photography-based focus groups about sexuality and relationships. Twenty-three participants (10 boys and 13 girls) were recruited from three urban schools participating in a comprehensive sex education impact evaluation in the Northeast. We analyzed conversational narratives that were elicited in a group process while sharing photos of important people, contexts, and situations, showcasing participants' exploration of sexuality and relationships. Our analysis revealed four main themes: (a) direct and indirect family communication about sexuality, (b) accidental and intentional Internet usage, (c) shared and contested peer knowledge, and (d) school as a direct and indirect learning context. Implications and future directions for practice, research, and policy are explored.

    Fractures are a common finding in children and it is estimated that 2.1% of all children will suffer at least one fracture before the age of 16. With young children in particular, the question may arise if this is related to child abuse. The aim of this book is to help physicians involved in child abuse cases to interpret radiological findings in light of the forensic circumstances under which they occurred. The authors present up-to-date literature related to the mechanisms underlying non-accidental cases of trauma. In this book not only the radiological findings in child-abuse are discussed, but more importantly, these findings are analyzed from a forensic perspective. Careful attention is paid to evidence regarding reported trauma mechanisms and their clinical outcome; for example, can a fall from a couch result in a femoral fracture, and if not, where is the supporting evidence?

    While topical thrombin application can markedly improve surgical hemostasis, rapid absorption of thrombin can result in pulmonary embolism and death. We report a case of accidental interstitial infiltration of topical thrombin after hemorrhoidectomy that was treated with administration of human antithrombin and heparin anticoagulation. Except for a marked decrease in antithrombin activity from super normal to normal values, the patient exhibited no laboratory or clinical signs of pulmonary embolism, thrombin mediated consumptive loss of procoagulants, or regional thrombosis. The patient had an uncomplicated recovery without sign of thrombotic morbidity. While it is hoped that such a medical misadventure should not occur, our case may serve as a reference to guide anticoagulant therapy if such a clinical scenario arises.

    Full Text Available Notwithstanding the enforcement of ATEX EU Directives (94/9/EC of 23 March 1994 and safety management system application, explosions in the coal sector still claim lives and cause huge economic losses. Even a consolidated activity like coke dry distillation allows the opportunity of preventing explosion risk connected to fugitive emissions of coke oven gas. Considering accidental releases under semi-confined conditions, a simplified mathematical approach to the maximum allowed gaseous build-up is developed on the basis of the intrinsic hazards of the released compound. The results will help identifying and assessing low rate release consequences therefore to set-up appropriate prevention and control measures. The developed methodology was tested at the real-scale and validated by numerical computational fluid dynamics (CFD simulations showing the effectiveness of the methodology to evaluate and mitigate the risk connected to confined hazardous releases.

    Animal cruelty is defined as a deliberate action that causes pain and suffering to an animal. In Brazil, legislation known as the Environmental Crimes Law states that cruelty toward all animal species is criminal in nature. From 644 domestic cats necropsied between January 1998 and December 2009, 191 (29.66%) presented lesions highly suggestive of animal cruelty. The main necroscopic finding was exogenous carbamate poisoning (75.39%) followed by blunt-force trauma (21.99%). Cats from 7 months to 2 years of age were the most affected (50.79%). In Brazil, violence is a public health problem and there is a high prevalence of domestic violence. Therefore, even if laws provide for animal welfare and protection, animals are common targets for violent acts. Within a context of social violence, cruelty toward animals is an important parameter to be considered, and the non-accidental lesions that were found are evidence of malicious actions.

    Chronic exposure to chlorine gas has been shown to cause occupational asthma. Acute inhalation of chlorine is known to cause airway inflammation and induce airway nitric oxide formation. Exhaled nitric oxide may therefore be a marker of airway damage after chlorine gas exposure. After accidental chlorine gas exposure in a swimming pool, exhaled nitric oxide and pulmonary function were repeatedly measured in 18 children over a 1-mo period. Symptomatic children with impaired pulmonary function had higher nitric oxide levels on the day after the exposure compared to day 8 and day 28. Differences in exhaled nitric oxide were more pronounced at a higher exhalation flow compared to lower flow, suggesting peripheral rather than central airway damage. This was in accordance with the observed changes in pulmonary function. No changes in exhaled nitric oxide were seen in asymptomatic children. These data suggest that acute chlorine gas exposure results in a mild increase of exhaled nitric oxide in symptomatic children.

    Highly toxic hydrogen selenide and hydrogen sulfide gases are used in the production of copper-indium-diselenide photovoltaic cells by reactive sputtering. In the event of an accident, these gases may be released to the atmosphere and pose hazards to public and occupational safety and health. This paper outlines an approach for designing systems for the control of these releases given the uncertainty in release conditions and lack of data on the chemical systems involved. Accidental releases of these gases in storage cabinets can be controlled by either a venturi and packed-bed scrubber and carbon adsorption bed, or containment scrubbing equipment followed by carbon adsorption. These systems can effectively reduce toxic gas emissions to levels needed to protect public health. The costs of these controls (˜0.012/Wp) are samll in comparison with current (˜6/Wp) and projected (˜I/Wp) production costs.

    Carbon monoxide poisoning is common and carries significant morbidity and mortality. The nervous system, particularly the brain, is frequently affected by it, owing to its high metabolic activity and oxygen requirements. Carbon monoxide damages the nervous system by both hypoxic and inflammatory mechanisms. Central diabetes insipidus is an extremely rare complication of carbon monoxide poisoning. Herein, we report the case of a young lady, who developed this complication and severe hypernatremia after accidental carbon monoxide poisoning. She also developed a hyperglycemic hyperosmolar state during the treatment for hypernatremia. To the best of our knowledge, both these entities have not been reported together in association with carbon monoxide poisoning. The purpose of this article is to emphasize the anticipation and early recognition of central diabetes insipidus in carbon monoxide poisoning. This can prevent severe hypernatremia and complications associated with its presence and treatment.

    2008-03-01

    In the present paper the accidental release of toxic chemicals has been taken into consideration, and a sensitivity analysis study of the corresponding consequences calculation has been carried out. Four different toxic chemicals have been chosen for the simulations, and the effect of the variability of the main input parameters on the extension of the impact areas has been assessed. The results show that the influence of these parameters depends on the physical properties of the released substance and that not always the widely known rules of thumb, such as the positive influence of the wind velocity on gas dispersion, apply. In particular, the boiling temperature of the chemical has revealed to be the main parameter affecting the type of dependence of the impact distances on the input variables.

    As one of the key safety issues of fusion reactors, tritium environmental impact of fusion accidents has attracted great attention. In this work, the dynamic tritium concentrations in the air and human body were evaluated on the time scale based on accidental release scenarios under the extreme environmental conditions. The radiation dose through various exposure pathways was assessed to find out the potential relationships among them. Based on this work, the limits of HT and HTO release amount for arbitrary accidents were proposed for the fusion reactor according to dose limit of ITER. The dynamic results aim to give practical guidance for establishment of fusion emergency standard and design of fusion tritium system. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available A hoard of pottery, metal lamps, mirrors and a lampad, accidentally discovered on the Uvek settlement site in 1994 is made public. The pottery items are represented by three Qashan pottery bowls with underglaze painting and a red-clay jug. The two bronze lamps demonstrate the nearest analogy to those found on the Tsarev fortified settlement site and belong to the type that was spread in the Golden Horde cities. The copper lampad is a product of Byzantine circle, also common in Russia. The two bronze mirrors were imported from China or were made according to Chinese tradition. The objects bear traces of a fire. The authors have concluded that the assemblage had belonged to a wealthy who resided in the Russian Christian quarter. The items were probably concealed in the 1360s as a result of the tragic events associated with the start of the "Great troubles" in the Golden Horde.

    The existence of closed loops of degeneracies in crystals has been intimately connected with associated crystal symmetries, raising the following question: What is the minimum symmetry required for topological character, and can one find an example? Triclinic CaAs3 , in the space group P 1 ¯ with only a center of inversion, has been found to display, without need for tuning, a nodal loop of accidental degeneracies with topological character, centered on one face of the Brillouin zone that is otherwise fully gapped. The small loop is very flat in energy, yet is cut four times by the Fermi energy, a condition that results in an intricate repeated touching of inversion related pairs of Fermi surfaces at Weyl points. Spin-orbit coupling lifts the fourfold degeneracy along the loop, leaving trivial Kramers pairs. With its single nodal loop that emerges without protection from any point group symmetry, CaAs3 represents the primal "hydrogen atom" of nodal loop systems.

    This report contains an assessment of the radiological impact on the Greater London population of postulated accidental releases from the Sizewell PWR. Three of the degraded core accident releases postulated by the CEGB are analysed. The consequences, conditional upon each release, are evaluated in terms of the health impact on the exposed population and the impact of countermeasures taken to limit the exposure. Consideration is given to the risk to the Greater London population as a whole and to individuals within it. The consequences are evaluated using the NRPB code MARC (Methodology for Assessing Radiological Consequences). The results presented in this report are all conditional upon the occurrence of each release. In assessing the significance of the results, due account must be taken of the frequency with which such releases may be predicted to occur.

    To describe the factors associated with outcome after accidental deep hypothermia. We conducted a retrospective cohort study on patients with accidental hypothermia (core temperature <28 °C) admitted to a Level I emergency room over a 10-year period. Forty-eight patients were included with a median temperature of 26 °C (range, 16.3-28 °C) on admission. The etiology of hypothermia was exposure to a cold environment (n = 27), avalanche (n = 13) or immersion in cold water (n = 8). Mean age was 47 ± 22 years, and 58% were males. Thirty-two patients had a cardiac arrest (CA): 15 patients presented unwitnessed cardiac arrest (UCA) and 17 patients presented rescue collapse (RC). Extracorporeal life support (ECLS) was implemented in 21 patients with refractory cardiac arrest and in two patients with hemodynamic instability. Overall mortality was 50%. For cardiac arrest patients, only three out of 15 patients with UCA survived at day 28, whereas eight out of 17 patients with RC survived. The cerebral performance category score was 4 for all the survivors of UCA and 1 [range, 1-2] for survivors of RC. Patients with poor outcome presented more UCA, a lower pH, a higher serum potassium, creatinine, serum sodium or lactate level as well as more severe coagulation disorders. Cardiac arrest related to rescue collapse was associated with favorable outcome. On-scene rescue collapse should prompt prolonged resuscitation and ECLS rewarming in all CA patients with deep hypothermia. Conversely, unwitnessed cardiac arrest was associated with unfavorable outcome and will likely not benefit from ECLS. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Background: The primary aim of this study was to compare the incidence of accidental arterial puncture during right internal jugular vein (RIJV cannulation with and without ultrasound guidance (USG. The secondary end points were to assess if USG improves the chances of successful first pass cannulation and if BMI has an impact on incidence of arterial puncture and the number of attempts that are to be made for successful cannulation. Settings and Design: Prospective observational study performed at a single tertiary cardiac care center. Material and methods: 255 consecutive adult and pediatric cardiac surgical patients were included. In Group I (n = 124 USG was used for the right internal jugular vein cannulation and in Group II (n = 81 it was not used. There were 135 adult patients and 70 pediatric patients. Statistical analysis: Demographic and categorical data were analyzed using Student 't' test and chi- square test was used for qualitative variables. Results: The overall incidence of accidental arterial puncture in the entire study population was significantly higher when ultrasound guidance was not used (P< 0.001. In subgroup analysis, incidence of arterial puncture was significant in both adult (P = 0.03 and pediatric patients (P< 0.001 without USG. First attempt cannulation was more often possible in pediatric patients under USG (P = 0.03. In adult patients USG did not improve first attempt cannulation except in underweight patients. Conclusions: USG helped in the avoidance of inadvertent arterial puncture during RIJV cannulation and simultaneously improved the chances of first attempt cannulation in pediatric and in underweight adult cardiac surgical patients.

    Full Text Available Abstract Background Accidental falls among inpatients are a substantial cause of hospital injury. A number of successful experimental studies on fall prevention have shown the importance and efficacy of multifactorial intervention, though success rates vary. However, the importance of staff compliance with these effective, but often time-consuming, multifactorial interventions has not been fully investigated in a routine clinical setting. The purpose of this observational study was to describe the effectiveness of a multidisciplinary quality improvement (QI activity for accidental fall prevention, with particular focus on staff compliance in a non-experimental clinical setting. Methods This observational study was conducted from July 2004 through December 2010 at St. Luke’s International Hospital in Tokyo, Japan. The QI activity for in-patient falls prevention consisted of: 1 the fall risk assessment tool, 2 an intervention protocol to prevent in-patient falls, 3 specific environmental safety interventions, 4 staff education, and 5 multidisciplinary healthcare staff compliance monitoring and feedback mechanisms. Results The overall fall rate was 2.13 falls per 1000 patient days (350/164331 in 2004 versus 1.53 falls per 1000 patient days (263/172325 in 2010, representing a significant decrease (p = 0.039. In the first 6 months, compliance with use of the falling risk assessment tool at admission was 91.5% in 2007 (3998/4368, increasing to 97.6% in 2010 (10564/10828. The staff compliance rate of implementing an appropriate intervention plan was 85.9% in 2007, increasing to 95.3% in 2010. Conclusion In our study we observed a substantial decrease in patient fall rates and an increase of staff compliance with a newly implemented falls prevention program. A systematized QI approach that closely involves, encourages, and educates healthcare staff at multiple levels is effective.

    Full Text Available To the best of our knowledge, imaging of accidental exposure to radioactive fluorine-18 (F-18 due to liquid spill has not been described earlier in the scientific literature. The short half-life of F-18 (t½=110 min, current radiation safety requirements, and Good Manufacturing Practice (GMP regulations on radiopharmaceuticals have restrained the occurrence of these incidents. The possibility of investigating this type of incidents by gamma and positron imaging is also quite limited. Additionally, a quick and precise analysis of radiochemical contamination is cumbersome and sometimes challenging if the spills of radioactive materials are low in activity. Herein, we report a case of accidental F-18 contamination in a service person during a routine cyclotron maintenance procedure. During target replacement, liquid F-18 was spilled on the person responsible for the maintenance. The activities of spills were immediately measured using contamination detectors, and the photon spectrum of contaminated clothes was assessed through gamma spectroscopy. Despite protective clothing, some skin areas were contaminated, which were then thoroughly washed. Later on, these areas were imaged, using positron emission tomography (PET, and a gamma camera (including spectroscopy. Two contaminated skin areas were located on the hand (9.7 and 14.7 cm2, respectively, which showed very low activities (19.0 and 22.8 kBq respectively at the time of incident. Based on the photon spectra, F-18 was confirmed as the main present radionuclide. PET imaging demonstrated the shape of these contaminated hot spots. However, the measured activities were very low due to the use of protective clothing. With prompt action and use of proper equipments at the time of incident, minimal radionuclide activities and their locations could be thoroughly analyzed. The cumulative skin doses of the contaminated regions were calculated at 1.52 and 2.00 mSv, respectively. In the follow-up, no skin

    To evaluate the short term and long term respiratory health effects of subjects who accidentally exposed to high concentration of chlorine gas. There was an accidental leakage of sodium hypochlorite from an industrial factory in Rayong province in June 2010. Medical records of those who developed severe symptoms after exposed to high concentration of chlorine gas were reviewed. Prospective observational study was conducted after hospital discharge by interviewing with respiratory health questionnaires, physical examination, spirometry, methacholine challenge test, and home peak expiratory flow (PEF) monitoring at 2, 5 and 8 months after the event. Among 1,434 persons exposed to chlorine gas, 92 developed severe symptoms required hospital admission and 21 participated in the follow-up study at 2 months there after. Respiratory symptoms were noted in 18 participants. Three most common symptoms were dyspnea (81%), chest tightness (71%), and cough (67%). Obstructive defect from spirometry was identified in 2 participants, one of which also had bronchial hyper responsiveness (BHR) compatible with reactive airway dysfunction syndrome (RADS). Seven participants had abnormal PEF variability. There were 10 and 5 participants left in the follow-up visit at 5 and 8 months respectively. Two participants had persistent obstructive defect with additional two subjects were noticed. Those who had BHR and abnormal PEF variability remained unchanged. Acute exposure to high concentration of chlorine gas causes both significant short and long term respiratory health effects. Most of the patients although have gradual improvement of respiratory symptoms, but some symptoms remain persistent. Few patients have lung function impairment lasting for at least 8 months.

    To study the clinical presentation, pulmonary functions and outcomes in subjects who were accidentally exposed to chlorine gas. Prospective observational study of 64 patients who sustained acute accidental exposure to chlorine gas during a leak in the chlorination system of the public bathing pool of a temple. The major presenting symptoms and signs included acute dyspnoea (100%), chest discomfort (100%), cough (97%), eye irritation (88%), giddiness (72%), vomiting (46%), and heaviness in the head (44%); tachycardia (100%), tachypnoea (96%) and polyphonic wheezing (28%). All patients were managed in the emergency room with humidified oxygen inhalation and beta-2 agonist nebulisation and 52 were discharged within six hours. Twelve patients were severely affected and required hospitalisation; three of them were admitted into the intensive care unit. Three patients developed pulmonary oedema six to eight hours following admission. Pulmonary function testing (n = 12) at presentation revealed obstructive defect in eight and mixed obstructive-cum-restrictive defect in four patients. The mean duration of hospital stay was 5.1 +/- 2.1 days. None of the patients died. Reactive airway dysfunction syndrome (RADS) was observed in three of the 12 hospitalised patients, who complained of manifested persistent cough that lasted for three months period following discharge. Serial pulmonary functions recovered to normal range by the end of the six months in all patients and remained so at one-year follow-up. Acute exposure to chlorine gas is an uncommon, but important public health hazard and can cause RADS, acute lung injury and pulmonary function abnormalities, which are reversible on prompt and appropriate management.

  3. Circumstances and factors associated with accidental deaths among children, adolescents and young adults in Cuiaba, Brazil

    Christine Baccarat de Godoy Martins

    Full Text Available CONTEXT AND OBJECTIVE Analysis on accidents from the perspective of population segments shows there is higher incidence among children, adolescents and young adults. Since the characteristics and circunstances of the event are closely related to educational, economic, social and cultural issues, identifying them may contribute towards minimizing the causes, which are often fatal. The aim here was to identify the environmental, chemical, biological and cultural factors associated with deaths due to accidents among children, adolescents and young adults in Cuiabá, in 2009. DESIGN AND SETTING This was a descriptive cross-sectional study conducted in Cuiabá, Mato Grosso, Brazil. RESULTS Thirty-nine accidental deaths of individuals aged 0 to 24 years were examined: 56.4% due to traffic accidents; 25.6%, drowning; 10.3%, aspiration of milk; 5.1%, falls; and 2.6%, accidentally triggering a firearm. Male victims predominated (82.1%. The presence of chemical, environmental and biological risk factors was observed in almost all of the homes. Regarding cultural factors and habits, a large proportion of the families had no idea whether accidents were foreseeable events and others did not believe that the family's habits might favor their occurrence. Delegation of household chores or care of younger siblings to children under the age of 10 was common among the families studied. CONCLUSION The results point towards the need to have safe and healthy behavioral patterns and environments, and to monitor occurrences of accidents, thereby structuring and consolidating the attendance provided for victims.

    Thermal injuries are a frequent cause of accidents within the pediatric population that may result in long periods of hospitalization as well as severe physical and mental impairment and lifelong consequences. Especially in infants, burns caused by scalding are the most common cause of injury. Beside accidental injuries, intential burns may also occur. It is of utmost importance to differentiate between intentional and accidental burns, yet the distinction can be very demanding for physicians, nurses and social workers. In this retrospective multicenter study, thermally inflicted burns in Germany were analyzed over a period of 10 years. Data of 13.353 pediatric patients with thermal injuries from 32 hospitals were analyzed within the period of 2006 to 2015. The study results show that 0,5% of all burns were inflicted. This percentage seems to be an inadequate represention as compared to reported international surveys, which report an average of 10% of all burns being inflicted in pediatric patients. When comparing our results to international survey results, it can be assumed that a large number of child abuse cases go undetected within the German pediatric population. In particular awareness of intentional burns needs to be raised and detection strategies, as presented in this paper, implemented. In the future, a more precise collection of data of burned children is necessary to illustrate the true number of intentional pediatric burns in Germany. This has been implemented by the renewed pediatric burn registry of the German Society for Burn Treatment (DGV) and the working group "The severely burned child". © Georg Thieme Verlag KG Stuttgart · New York.

    Accidental hypothermia is a condition associated with significant morbidity and mortality. Hypothermia has been reported to affect left ventricular systolic and diastolic function. However, most of the data come from animal experimental studies. The purpose of the present study was to assess the impact of severe accidental hypothermia on systolic and diastolic ventricular function in patients treated using veno-arterial extracorporeal membrane oxygenation (ECMO). We prospectively assessed nine hypothermic patients (8 male, age 25-78 years) who were transferred to the Severe Accidental Hypothermia Center and treated with ECMO. Transthoracic echocardiography was performed on admission (in patients without cardiac arrest) and on discharge from ICU after achieving cardiovascular stability. Cardiorespiratory stability and full neurologic recovery was achieved in all patients. Biomarkers of myocardial damage (CK, CKMB, hsTnT) were significantly elevated in all study patients. Admission echocardiography performed in patients in sinus rhythm, revealed moderate-severe bi-ventricular systolic dysfunction and moderate bi-ventricular diastolic dysfunction. Discharge echocardiography showed persistent mild bi-ventricular diastolic dysfunction, although systolic function of both ventricles returned to normal. Discharge echocardiography in patients admitted with cardiac arrest showed normal (5 patients) or moderately impaired (1 patient) global LV systolic function on discharge. However, mild or moderate LV diastolic dysfunction was observed in all 6 patients. Discharge RV systolic function was normal, whereas mild RV diastolic dysfunction was present in these patients. After severe accidental hypothermia bi-ventricular diastolic dysfunction persists despite systolic function recovery in survivors treated with ECMO.

    Since its introduction in 1980, the percutaneous endoscopic gastrostomy (PEG) tube has become an efficient means of providing long-term enteral access. Conveniently, the soft inner bumper allows PEG removal with relatively minimal external traction. Consequently, a major complication is accidental dislodgement, from which significant morbidity may occur. Clinicians have perhaps underestimated and underappreciated this complication, not only in the acute setting but over the lifetime of the PEG tube. A retrospective analysis of PEG placements conducted at the authors' institution identified all PEG tubes placed between July 1, 2007 and July 1, 2010 by one faculty surgeon. Patient charts were reviewed for 30-day mortality, complications, and subsequent management. Patients were reviewed until intentional removal of the PEG, cessation of records, or patient mortality. A total of 563 PEGs were identified. The 30-day mortality rate was 7.8% (44/563), and the 7-day early accidental dislodgement rate was 4.1% (23/563). The total lifetime accidental PEG dislodgement rate was 12.8% (72/563). Of the 72 dislodged PEGs, 49 occurred after discharge from rehabilitation or nursing facilities. The vast majority required an emergency department visit, a level 3 surgical consultation, a replacement gastrostomy tube, and a radiographic confirmation of tube positioning, resulting in charges totaling an average of $1,200. Many large PEG reviews report an early accidental dislodgement rate of 0.6% to 4.0%. The most clinically significant accidental removals occur in the first 7 days after placement, and open gastrostomy may cause obvious morbidity. The early dislodgement rate in this study (4.1%) is consistent with those currently reported. However, if cases are followed longitudinally, a significantly higher rate of late dislodgement (12.8%) is seen. Frequently placed into neurologically impaired or elderly patients, the PEGs that dislodge months and years later require expensive

    Several air dispersion models are available for prediction and simulation of the hazard areas associated with accidental releases of toxic gases. The most model packages (commercial or free of charge) include a chemical database, an intuitive graphical user interface (GUI) and automated graphical output for effective presentation of results. The models are designed especially for analyzing different accidental toxic release scenarios ("worst-case scenarios”), preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management. The research project RETOMOD (reference scenarios calculations for toxic gas releases - model systems and their utility for the fire brigade) was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG) in cooperation with the Viennese fire brigade, OMV Refining & Marketing GmbH and Synex Ries & Greßlehner GmbH. RETOMOD was funded by the KIRAS safety research program of the Austrian Ministry of Transport, Innovation and Technology (www.kiras.at). The main tasks of this project were 1. Sensitivity study and optimization of the meteorological input for modeling of the hazard areas (human exposure) during the accidental toxic releases. 2. Comparison of several model packages (based on reference scenarios) in order to estimate the utility for the fire brigades. For the purpose of our study the following models were tested and compared: ALOHA (Areal Location of Hazardous atmosphere, EPA), MEMPLEX (Keudel av-Technik GmbH), Trace (Safer System), Breeze (Trinity Consulting), SAM (Engineering office Lohmeyer).

    Despite the well-recognised benefits of sport, there are also negative influences on athlete health, well-being and integrity caused by non-accidental violence through harassment and abuse. All athletes have a right to engage in 'safe sport', defined as an athletic environment that is respectful, equitable and free from all forms of non-accidental violence to athletes. Yet, these issues represent a blind spot for many sport organisations through fear of reputational damage, ignorance, silence or collusion. This consensus statement extends the 2007 IOC Consensus Statement on Sexual Harassment and Abuse in Sport, presenting additional evidence of several other types of harassment and abuse-psychological, physical and neglect. All ages and types of athletes are susceptible to these problems but science confirms that elite, disabled, child and lesbian/gay/bisexual/trans-sexual (LGBT) athletes are at highest risk, that psychological abuse is at the core of all other forms and that athletes can also be perpetrators. Harassment and abuse arise from prejudices expressed through power differences. Perpetrators use a range of interpersonal mechanisms including contact, non-contact/verbal, cyber-based, negligence, bullying and hazing. Attention is paid to the particular risks facing child athletes, athletes with a disability and LGBT athletes. Impacts on the individual athlete and the organisation are discussed. Sport stakeholders are encouraged to consider the wider social parameters of these issues, including cultures of secrecy and deference that too often facilitate abuse, rather than focusing simply on psychopathological causes. The promotion of safe sport is an urgent task and part of the broader international imperative for good governance in sport. A systematic multiagency approach to prevention is most effective, involving athletes, entourage members, sport managers, medical and therapeutic practitioners, educators and criminal justice agencies.

    The risk of transmitting contagious diseases by accidental needle-stick injury has raised a considerable amount of concern among hospital staff. Before generalized vaccination in the early 80s, there was a high risk of hepatitis B transmission. More recently, the development of reliable techniques of detecting serum markers has made it possible to precisely evaluate the risk for hepatitis C. The risk of contamination by the hepatitis C virus by accidental needle-stick injury can be estimated at 0 to 3%, and can only reach a maximum of 10% when the patient is positive for hepatitis C RNA. The risk is thus less than for hepatitis B virus (7 to 30%). The low rate of transmission probably results from the quantity of viral material in blood and secretions. In populations of health personnel exposed to a risk of septic needle-stick injury, the prevalence of anti-hepatitis C virus antibodies has been observed in several studies at rates between 0 and 2%. This is similar to non-exposed populations and would be an argument suggesting that there is a low risk of hepatitis C virus transmission. Nevertheless, because hospital staff is frequently exposed to blood and because a significant number of patients are positive for anti-hepatitis C virus antibodies, adequate preventive measures must be taken. The Immunization Practice Advisory Committee (USA) recommends injection of polyvalent gammaglobulins when stick injury occurs with a needle used for a hepatitis C virus antibody positive patient, but the effectiveness of this protocol has not been demonstrated. Several preliminary studies suggest that treatment of hepatitis C in the acute phase could significantly reduce the rate of chronicity. When interferon has been authorized for this indication, and if effectiveness is confirmed, treatment might be recommended for health personnel with acute needle-stick transmitted HCV infection. Infected needle-stick victims might be followed by having their transaminases checked 4

    Understanding spatial and temporal patterns of microbial conversion of nitrate (NO3-) to nitrogen (N) gas (denitrification) is important for predicting permanent losses of reactive N from systems. In many landscapes, wetlands serve as hotpots of denitrification by providing optimal condition for denitrifiers (sub-oxic, carbon-rich sediments). Much research on denitrification has occurred in non-urban or highly managed urban wetlands. However, in urban landscapes N-rich stormwater is often discharged into areas not designed or managed to reduce N loads. "Accidental" wetlands forming at these outfalls may have the capacity to remove NO3-; however, these "accidental" urban wetlands can contain novel soils and vegetation, and are subject to unique hydrologic conditions that could create spatial and temporal patterns of denitrification that differ from those predicted in non-urban counterparts. We performed denitrification enzyme assays (measuring denitrification potential, or DP) on soil samples taken from nine wetlands forming at storm drain outfalls in Phoenix, AZ. The wetlands ranged from perennially flooded, to intermittently flooded (~9 months/year), to ephemerally flooded (2-3 weeks/year). To assess spatial variation in carbon availability to denitrifiers, samples were taken from 3-4 dominant vegetation patch types within each wetland. To assess temporal variation in DP, samples were taken across three seasons differing in rainfall pattern. We found small- and large-scale spatiotemporal patterns in DP that have important implications for management of urban wetlands for stormwater quality. DP varied among plant patches and was typically highest in patches of Ludwigia peploides, indicating that plant species type may mediate within-wetland variations in carbon availability, and therefore NO3- removal capacity. We found a range of responses in DP among wetlands to season, which appeared to be driven in part by flood regime: DP in perennially-flooded wetlands was

    The Fukushima nuclear accident resulted in the largest ever accidental release of artificial radionuclides in coastal waters. This accident has shown the importance of marine assessment capabilities for emergency response and the need to develop tools for adequately predicting the evolution and potential impact of radioactive releases to the marine environment. The French Institute for Radiological Protection and Nuclear Safety (IRSN) equips its emergency response centre with operational tools to assist experts and decision makers in the event of accidental atmospheric releases and contamination of the terrestrial environment. The on-going project aims to develop tools for the management of marine contamination events in French coastal areas. This should allow us to evaluate and anticipate post-accident conditions, including potential contamination sites, contamination levels and potential consequences. In order to achieve this goal, two complementary tools are developed: site-specific marine data sheets and a dedicated simulation tool (STERNE, Simulation du Transport et du transfert d'Eléments Radioactifs dans l'environNEment marin). Marine data sheets are used to summarize the marine environment characteristics of the various sites considered, and to identify vulnerable areas requiring implementation of population protection measures, such as aquaculture areas, beaches or industrial water intakes, as well as areas of major ecological interest. Local climatological data (dominant sea currents as a function of meteorological or tidal conditions) serving as the basis for an initial environmental sampling strategy is provided whenever possible, along with a list of possible local contacts for operational management purposes. The STERNE simulation tool is designed to predict radionuclide dispersion and contamination in seawater and marine species by incorporating spatio-temporal data. 3D hydrodynamic forecasts are used as input data.

    The transgenic traits associated with the majority of commercial genetically modified crops are focused on improving herbicide and insecticide management practices. The use of the transgenic technology in these crops and the associated chemistry has been the basis of studies that provide evidence for occasional improvement in environmental benefits due to the use of less residual herbicides, more targeted pesticides, and reduced field traffic. This is nicely exemplified through studies using Environmental Impact Quotient (EIQ) assessments. Whilst EIQ evaluations may sometimes illustrate environmental benefits they have their limitations. EIQ evaluations are not a surrogate for Environmental Risk Assessments and may not reflect real environmental interactions between crops and the environment. Addressing the impact cultivated plants have on the environment generally attracts little public attention and research funding, but the introduction of GM has facilitated an expansion of research to address potential environmental concerns from government, NGOs, industry, consumers, and growers. In this commentary, some evidence from our own research and several key papers that highlight EIQ assessments of the impact crops are having on the environment are presented. This information may be useful as an education tool on the potential benefits of GM and conventional farming. In addition, other deliberate, accidental, and GM-driven benefits derived from the examination of GM cropping systems is briefly discussed.

  3. Features of the Asynchronous Correlation between the China Coal Price Index and Coal Mining Accidental Deaths.

    Full Text Available The features of the asynchronous correlation between accident indices and the factors that influence accidents can provide an effective reference for warnings of coal mining accidents. However, what are the features of this correlation? To answer this question, data from the China coal price index and the number of deaths from coal mining accidents were selected as the sample data. The fluctuation modes of the asynchronous correlation between the two data sets were defined according to the asynchronous correlation coefficients, symbolization, and sliding windows. We then built several directed and weighted network models, within which the fluctuation modes and the transformations between modes were represented by nodes and edges. Then, the features of the asynchronous correlation between these two variables could be studied from a perspective of network topology. We found that the correlation between the price index and the accidental deaths was asynchronous and fluctuating. Certain aspects, such as the key fluctuation modes, the subgroups characteristics, the transmission medium, the periodicity and transmission path length in the network, were analyzed by using complex network theory, analytical methods and spectral analysis method. These results provide a scientific reference for generating warnings for coal mining accidents based on economic indices.

    Full Text Available Abstract Introduction Carbon monoxide poisoning is easy to diagnose when there is a history of exposure. When the exposure history is absent, or delayed, the diagnosis is more difficult and relies on recognising the importance of multi-system disease. We present a case of accidental carbon monoxide poisoning. Case presentation A middle-aged man, who lived alone in his mobile home was found by friends in a confused, incontinent state. Initial signs included respiratory failure, cardiac ischaemia, hypotension, encephalopathy and a rash, whilst subsequent features included rhabdomyolysis, renal failure, amnesia, dysarthria, parkinsonism, peripheral neuropathy, supranuclear gaze palsy and cerebral haemorrhage. Despite numerous investigations including magnetic resonance cerebral imaging, lumbar puncture, skin biopsy, muscle biopsy and electroencephalogram a diagnosis remained elusive. Several weeks after admission, diagnostic breakthrough was achieved when the gradual resolution of the patient's amnesia, encephalopathy and dysarthria allowed an accurate history to be taken for the first time. The patient's last recollection was turning on his gas heating for the first time since the spring. A gas heating engineer found the patient's gas boiler to be in a dangerous state of disrepair and it was immediately decommissioned. Conclusion This case highlights several important issues: the bewildering myriad of clinical features of carbon monoxide poisoning, the importance of making the diagnosis even at a late stage and preventing the patient's return to a potentially fatal toxic environment, and the paramount importance of the history in the diagnostic method.

  5. Dynamic Analysis of Cable-Stayed Bridges Affected by Accidental Failure Mechanisms under Moving Loads

    2013-01-01

    Full Text Available The dynamic behavior of cable-stayed bridges subjected to moving loads and affected by an accidental failure in the cable suspension system is investigated. The main aim of the paper is to quantify, numerically, the dynamic amplification factors of typical kinematic and stress design variables, by means of a parametric study developed in terms of the structural characteristics of the bridge components. The bridge formulation is developed by using a geometric nonlinear formulation, in which the effects of local vibrations of the stays and of large displacements in the girder and the pylons are taken into account. Explicit time dependent damage laws, reproducing the failure mechanism in the cable system, are considered to investigate the influence of the failure mode characteristics on the dynamic bridge behavior. The analysis focuses attention on the influence of the inertial characteristics of the moving loads, by accounting coupling effects arising from the interaction between girder and moving system. Sensitivity analyses of typical design bridge variables are proposed. In particular, the effects produced by the moving system characteristics, the tower typologies, and the failure mode characteristics involved in the cable system are investigated by means of comparisons between damaged and undamaged bridge configurations.

    Injuries caused by accidents or violent situations in pediatric patients are a serious social problem where prevention plays a key role. The aim of this study was to describe the epidemiological situation of pediatric injuries in Spain. A prospective study of pediatric patients receiving care in the Emergency Service of the Complejo Hospitalario de Navarra due to for reasons of accidental injury was conducted. The study covered a period of 1 year and assessed a total of 16 variables. There were a total of 8,876 patients, of whom 56.4% were males. Traumatic injuries such as fractures and craniocerebral trauma were identified as the most frequent injuries, occurring as a result of injuries mainly in the home. In females, there was a decrease in the incidence of injuries related to age. There was a greater incidence at the end of the day, during the weekend, and in the months of March to October. The epidemiological profile of pediatric patients who met with accidents in Navarra, Spain, is described. The knowledge of the main areas and factors related to injuries allows us to improve preventive measures, which would contribute to better control in this region of Spain.

    A case of accidental Freon 22 (monochlorodifluoromethane) poisoning in a fishing vessel is reported. Forensic autopsy revealed severe pulmonary edema and congestion (left lung; 576 g, right lung; 740 g). GC-MS analysis clearly showed that the deceased inhaled Freon 22 gas prior to his death. Freon 22 concentration was 169+/-7.0 microg/ml in the heart blood. The distribution pattern of Freon 22 in tissue samples was similar to that in previously reported cases. The brain had the highest concentration of Freon 22 followed by the spleen, liver, kidney and lung, respectively. Histopathologically, Oil red O staining of the liver showed many small, positive red areas in the cytosol, which have been reported in other cases of Freon 22 poisoning. However, Schmorl staining revealed that most areas of Oil red O positivity were lipofuscin granules. Lipofuscin in the liver, which closely relates to aging and other cell stresses, could have a relevance to Freon 22 exposure, but further experimental studies are needed to confirm it.

    Urine bioassay measurements for uranium and medical laboratory results were studied to determine whether there were any health effects from uranium intake among a group of 31 workers exposed to uranium hexafluoride (UF{sub 6}) and hydrolysis products following the accidental rupture of a 14-ton shipping cylinder in early 1986 at the Sequoyah Fuels Corporation uranium conversion facility in Gore, Oklahoma. Physiological indicators studied to detect kidney tissue damage included tests for urinary protein, casts and cells, blood, specific gravity, and urine pH, blood urea nitrogen, and blood creatinine. We concluded after reviewing two years of follow-up medical data that none of the 31 workers sustained any observable health effects from exposure to uranium. The early excretion of uranium in urine showed more rapid systemic uptake of uranium from the lung than is assumed using the International Commission on Radiological Protection (ICRP) Publication 30 and Publication 54 models. The urinary excretion data from these workers were used to develop an improved systemic recycling model for inhaled soluble uranium. We estimated initial intakes, clearance rates, kidney burdens, and resulting radiation doses to lungs, kidneys, and bone surfaces. 38 refs., 10 figs., 7 tabs.

  10. Game theory of pre-emptive vaccination before bioterrorism or accidental release of smallpox.

    Smallpox was eradicated in the 1970s, but new outbreaks could be seeded by bioterrorism or accidental release. Substantial vaccine-induced morbidity and mortality make pre-emptive mass vaccination controversial, and if vaccination is voluntary, then there is a conflict between self- and group interests. This conflict can be framed as a tragedy of the commons, in which herd immunity plays the role of the commons, and free-riding (i.e. not vaccinating pre-emptively) is analogous to exploiting the commons. This game has been analysed previously for a particular post-outbreak vaccination scenario. We consider several post-outbreak vaccination scenarios and compare the expected increase in mortality that results from voluntary versus imposed vaccination. Below a threshold level of post-outbreak vaccination effort, expected mortality is independent of the level of response effort. A lag between an outbreak starting and a response being initiated increases the post-outbreak vaccination effort necessary to reduce mortality. For some post-outbreak vaccination scenarios, even modest response lags make it impractical to reduce mortality by increasing post-outbreak vaccination effort. In such situations, if decreasing the response lag is impossible, the only practical way to reduce mortality is to make the vaccine safer (greater post-outbreak vaccination effort leads only to fewer people vaccinating pre-emptively). © 2015 The Author(s) Published by the Royal Society.

    Identifying the geochemical fingerprints of fluids that return to the surface after high volume hydraulic fracturing of unconventional oil and gas reservoirs has important applications for assessing hydrocarbon resource recovery, environmental impacts, and wastewater treatment and disposal. Here, we report for the first time, novel diagnostic elemental and isotopic signatures (B/Cl, Li/Cl, δ11B, and δ7Li) useful for characterizing hydraulic fracturing flowback fluids (HFFF) and distinguishing sources of HFFF in the environment. Data from 39 HFFFs and produced water samples show that B/Cl (>0.001), Li/Cl (>0.002), δ11B (25-31‰) and δ7Li (6-10‰) compositions of HFFF from the Marcellus and Fayetteville black shale formations were distinct in most cases from produced waters sampled from conventional oil and gas wells. We posit that boron isotope geochemistry can be used to quantify small fractions (∼0.1%) of HFFF in contaminated fresh water and likely be applied universally to trace HFFF in other basins. The novel environmental application of this diagnostic isotopic tool is validated by examining the composition of effluent discharge from an oil and gas brine treatment facility in Pennsylvania and an accidental spill site in West Virginia. We hypothesize that the boron and lithium are mobilized from exchangeable sites on clay minerals in the shale formations during the hydraulic fracturing process, resulting in the relative enrichment of boron and lithium in HFFF.

    A 26-year-old man, practicing for a variety performance as "fire-eater", accidentally inhaled and ingested about 10 ml petroleum. Soon afterwards he developed dyspnoea, an urge to cough, fever up to 39 degrees C and loss of retentiveness. He was treated as an out-patient with doxycycline, 100 mg daily, and aspirin, 500 mg three times daily. While this reduced the dyspnoea, the elevated temperature persisted and he had haemoptysis. Chest x-ray and computed tomography 12 days after the aspiration revealed areas of atelectasis and of liquefaction necroses. Bronchoscopic and cytological examinations showed eosinophilic alveolitis and mucosal necrosis in both main bronchi. The symptoms were improved by two inhalations of beclomethasone four times daily, and systemic treatment with prednisolone, 50 mg daily, together with parenteral antibiotic administration (cefotaxime, 1.0 g twice daily). The focal lung lesions regressed completely within a few weeks. Five months after the aspiration computed tomography merely demonstrated discrete scarring of the previously necrotic lesions. This case illustrates that, even with extensive necrotic lung changes after petroleum aspiration, conservative treatment is justified and likely to be effective.

    Over the past half century, a surprising number of major pollution incidents occurred due to tailings dam failures. Most previous studies of such incidents comprised forensic analyses of environmental impacts after a tailings dam failure, with few considering the combined pollution risk before incidents occur at a watershed-scale. We therefore propose Watershed-scale Tailings-pond Pollution Risk Analysis (WTPRA), designed for multiple mine tailings ponds, stemming from previous watershed-scale accidental pollution risk assessments. Transferred and combined risk is embedded using risk rankings of multiple routes of the "source-pathway-target" in the WTPRA. The previous approach is modified using multi-criteria analysis, dam failure models, and instantaneous water quality models, which are modified for application to multiple tailings ponds. The study area covers the basin of Gutanting Reservoir (the largest backup drinking water source for Beijing) in Zhangjiakou City, where many mine tailings ponds are located. The resultant map shows that risk is higher downstream of Gutanting Reservoir and in its two tributary basins (i.e., Qingshui River and Longyang River). Conversely, risk is lower in the midstream and upstream reaches. The analysis also indicates that the most hazardous mine tailings ponds are located in Chongli and Xuanhua, and that Guanting Reservoir is the most vulnerable receptor. Sensitivity and uncertainty analyses are performed to validate the robustness of the WTPRA method.

    This report updates, for 1980 through 1982, the results of continuing medical surveillance of a Marshallese population accidentally exposed to radioactive fallout in March 1954. The originally exposed Marshallese population comprised 64 persons on Rongelap Atoll who each received, on the average, an estimated 190 rads of absorbed external gamma radiation, 18 on Ailingnae Atoll who received 110 rads, and 159 on Utirik who received 11 rads. There were, in addition, 3 persons in utero on Rongelap, 1 person in utero on Ailingnae, and 8 persons in utero on Utirik who are considered exposed. The recipients of primary medical care include exposed and comparison populations as well as a rather large number of additional beneficiaries who are seen on a humanitarian basis of practical need and resource availability. In recent years, about 1400 people have been seen annually. This report, however, deals with four clearly defined groups: the remaining individuals who were exposed to radioactive fallout on Rongelap, Ailingnae, and Utirik in 1954 (including those in utero), and a comparison population of individuals from Rongelap who were unexposed. The number of persons now in each exposure category are 51, 12, 116, and 137, respectively. 100 references, 4 figures, 5 tables. (ACR)

    The entry of nuclear reactors into Earth's atmosphere resulting from an accidental or inadvertent abort of a space vehicle powered by nuclear-thermal rockets is investigated. The study is made for a typical piloted Mars mission vehicle incapacitated by an accident or malfunction during the Earth-arrival phase of the Mars-return journey due to simultaneous, multiple failures of its component systems. A single accident/abort scenario resulting in three entry possibilities is considered for a nominal hyperbolic in-bound approach velocity of 8 km/sec. The most severe case involving a direct entry is then analyzed over a broad range of approach velocities extending to 12 km/sec to include sprint-type missions. The results indicate that the severe surface heating, stagnation pressures, and g-loads are greater than 150 kW/sq cm, 300 atm, and 800-g, respectively. The wall heat transfer rate exceeds the value that can be accommodated by a carbon heatshield through radiation equilibrium prior to sublimation at 5500 K. These conditions are beyond our previous experience in crew safety, structural design, and thermal protection.

    Over the past half century, a surprising number of major pollution incidents occurred due to tailings dam failures. Most previous studies of such incidents comprised forensic analyses of environmental impacts after a tailings dam failure, with few considering the combined pollution risk before incidents occur at a watershed-scale. We therefore propose Watershed-scale Tailings-pond Pollution Risk Analysis (WTPRA), designed for multiple mine tailings ponds, stemming from previous watershed-scale accidental pollution risk assessments. Transferred and combined risk is embedded using risk rankings of multiple routes of the “source-pathway-target” in the WTPRA. The previous approach is modified using multi-criteria analysis, dam failure models, and instantaneous water quality models, which are modified for application to multiple tailings ponds. The study area covers the basin of Gutanting Reservoir (the largest backup drinking water source for Beijing) in Zhangjiakou City, where many mine tailings ponds are located. The resultant map shows that risk is higher downstream of Gutanting Reservoir and in its two tributary basins (i.e., Qingshui River and Longyang River). Conversely, risk is lower in the midstream and upstream reaches. The analysis also indicates that the most hazardous mine tailings ponds are located in Chongli and Xuanhua, and that Guanting Reservoir is the most vulnerable receptor. Sensitivity and uncertainty analyses are performed to validate the robustness of the WTPRA method. PMID:26633450

    The April 7, 1962 criticality accident involving human exposures was the first to have occurred in any production facility at Hanford. The accidental nuclear excursion did not result in any mechanical damage or spread of contamination. Three employees received over-exposure to gamma and neutron radiation. None were fatally exposed and in each case the over-exposure was recognized promptly. Following an initial period of medical observation and testing, the men were released to work. They continued to be followed clinically. Clinical studies performed were hematological procedures including leukocyte chromosome aberrations, morphologically aberrant blood cells, bone marrow evaluations, blood chemistry determinations, amino acid excretion studies, seminal fluid, urinary gonadotropins and estrogen excretion studies, testicular biopsies and crystalline lens examinations. These studies, along with a brief description of the accident and of the dosimetry, are summarized in this report by those participating in the studies. In view of the dose ranges received in these cases, both the negative and positive findings are considered to be of unusual interest due to the lack of knowledge of effects following human exposures at these levels.

    Fuels derived from non-petroleum renewable resources have raised interest due to their potential in replacing petroleum-based fuels, but information on their fate and effects in the terrestrial and aquatic environments in accidental spill scenario is limited. In this study, migration of four fuels (conventional diesel, conventional gasoline, renewable diesel NExBTL, and ethanol-blended gasoline RE85 containing maximum 85% ethanol) as non-aqueous phase liquids (NAPL) in soil was demonstrated in a laboratory-scale experiment. Ecotoxicity data was produced for the same fuels. There was no significant difference in migration of conventional and renewable diesel, but gasoline migrated 1.5 times deeper and 7-9 times faster in sand than diesel. RE85 spread horizontally wider but not as deep (p Daphnia magna and Vibrio fischeri, also demonstrating groundwater toxicity. The WAF of conventional gasoline and RE85 showed almost similar toxicity to both the aquatic test species. EC50 values of 1:10 (by volume) WAF were 9.9 %WAF (gasoline) and 9.3 %WAF (RE85) to D. magna and 9.3 %WAF (gasoline) and 12.3 %WAF (RE85) to V. fischeri. Low solubility decreased toxicity potential of conventional diesel in aquatic environment, but direct physical effects of oil phase pose a threat to organisms in nature. Renewable diesel NExBTL did not show clear toxicity to any test species.

    Non-accidental head injury (NAHI) is a major cause of neurological disability and death during infancy. Radiological imaging plays a crucial role in evaluating craniospinal injury, both for guiding medical management and the forensic aspects of abusive trauma. The damage sustained is varied, complex and may be accompanied by an evolving pattern of brain injury secondary to a cascade of metabolic and physiological derangements. Regrettably, many cases are poorly or incompletely evaluated leading to diagnostic errors and difficulties in executing subsequent child care or criminal proceedings. It is evident, from cases referred to the authors, that imaging protocols for NAHI are lacking (or only loosely adhered to, if present) in many centres throughout the U.K. Future research in this field will also be hampered if there is a lack of consistent and reliable radiological data. There is no nationally agreed protocol for imaging NAHI. We propose such a protocol, based upon a wide experience in the medical management of child abuse and extensive involvement in the medicolegal aspects of NAHI. Jaspan, T., et al. (2003).

    Post-exposure prophylaxis (PEP) relies on procedures allowing quick access to treatment in case of accidental exposure to viral risk (AEV). Occupational blood exposure (OBE) affects mainly caregivers; these accidents are monitored and assessed by the inter-regional center for nosocomial infections (C-CLIN), occupational physicians, and infection control units. They are classified apart from sexual exposure for which there is currently no monitoring. Data was extracted from the COREVIH (steering committee for the prevention of HIV infection) 2011 activity reports (AR), available online. Data collection was performed using a standardized grid. Twenty-four out of 28 AR were available online. Nine thousand nine hundred and twenty AEV were reported, 44% of OBE, and 56% of sexual and other exposures. PEP was prescribed in 8% of OBE and in 77% of sexual exposures. The type of PEP was documented in 52% of the cases. Follow-up was poorly documented. AR provide an incomplete and heterogeneous review of exposure management without any standardized data collection. The difficulties encountered in data collection and monitoring are due to differences in care centers (complex patient circuits, multiple actors) and lack of common dedicated software. Sexual exposures account for 50% of AEV and most are treated; but they are incompletely reported and consequently not analyzed at the regional or national level. A typical AR collection grid is being studied in 2 COREVIH, with the objective to improve collection and obtain useful national data. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available Objectives: Accidental hypothermia (AH is a potentially life-threatening condition that can lead to significant morbidity and life-long effects. Navy personnel are always at a greater risk of AH due to frequent outdoor work, wilderness exposure, prolonged immobility and exhaustion. The purpose of the survey was to assess Chinese Navy members’ awareness of AH and to make recommendations with regard to better measures for improving it. Methods: 111 Navy members completed a written questionnaire that was subsequently analyzed. Results: 30.6% of the respondents have experienced AH and 64.9% rated their knowledge of AH as “low” or “none”. Over half of them identified the initial symptom of AH as obvious shivering (69.4% and apathy (45.0%. As for the aggravate symptoms, 60.9% chose the wrong answer of more obvious shivering instead of the right one—absence of shivering (5.4%. In the case of the treatment of mild AH, more than half of the respondents chose the wrong answers. Conclusions: This study suggests that the basic skills of recognition and treatment of AH are inadequate in the Chinese Navy. Further work is required to develop a systematical, comprehensive and corresponding education method that would promote correct actions during AH.

    Hydrogen peroxide is a common household product. It is clear and odorless making it easy to confuse with water, especially when improperly stored. Concentrated formulations are also available for consumer purchase. We report a case of hydrogen peroxide ingestion in a child and discuss the potential consequences and treatment of such an exposure. A 12-year-old boy accidentally ingested a sip of concentrated hydrogen peroxide. He rapidly developed hematemesis and presented to the Emergency Department. His initial work-up was unremarkable, and his symptoms resolved quickly. However, diffuse gas emboli were found within the portal system on abdominal computed tomography. The child was treated with hyperbaric oxygen therapy and later found to have gastric irritation as well as an ulcer on endoscopy. He recovered fully from the incident. We present this case to increase awareness of the dangers of hydrogen peroxide ingestion in children. Fortunately, the child in this case recovered fully, but emergency physicians should be aware of the potential consequences and therapeutic options. Copyright © 2013 Elsevier Inc.

    The lack of data in the open literature on human exposure to the nerve agent O-ethyl-S-(2-diisopropylaminoethyl) methylphosphonothioate (VX) gives a special relevance to the data presented in this study in which we report the quantification of VX-butyrylcholinesterase adduct from a relatively low-level accidental human exposure. The samples were analyzed by gas chromatography-high resolution mass spectrometry using the fluoride ion regeneration method for the quantification of multiple nerve agents including VX. Six human plasma samples from the same individual were collected after the patient had been treated once with oxime immediately after exhibiting signs of exposure. Detection limits of approximately 5.5 pg/mL plasma were achieved for the G-analogue of VX (G-VX). Levels of the G-VX ranged from 81.4 pg/mL on the first day after the exposure to 6.9 pg/mL in the sample taken 27 days after the exposure. Based on the reported concentration of human butyrylcholinesterase in plasma of approximately 80 nM, it can be calculated that inhibition levels of >or= 0.05% of BuChE can be accurately quantified. These data further indicate that the fluoride ion regeneration method is a potentially powerful tool that can be used to assess low-level exposure to VX.

    Full Text Available The aim of this study was to analyze studies evaluating the association between the level of physical activity and the occurrence of accidental falls in the elderly. A systematic literature review of the LILACS and MEDLINE databases was conducted. As inclusion criteria, complete scientific articles investigating subjects older than 60 years, published in Portuguese, English or Spanish, were selected. Twenty-nine articles were retrieved, five from LILACS (1982 to 2007, two from MEDLINE (1966 to 1996, and 22 from MEDLINE (from 1997 to 2007. Ten (35% articles were selected based on the inclusion criteria and 19 (65% were excluded. A cross-sectional design was the most frequent type of study (60%. The studies identified suggest an association between the level of physical activity and factors related to the occurrence of falls such as functional disability, quality of life and independence to perform daily activities. Falls were found to restrict physical activity in some studies. In view of the heterogeneity of the studies in terms of methods and assessments, it was not possible to determine whether a better level of physical activity is able to decrease the incidence of falls in the elderly.

    CHEM{_}MACCS has been developed from the radiological accident consequence code, MACCS, to perform probabilistic calculations of potential off-site consequences of the accidental atmospheric release of hazardous chemicals. The principal phenomena considered in CHEM{_}MACCS are atmospheric transport, mitigative actions based on dose projection, dose accumulation by a number of pathways, and early and latent health effects. CHEM{_}MACCS provides the following capabilities: (1) statistical weather sampling data (8,760 hourly data points per year), (2) population dose and health effect risk calculations based on site-specific population data, (3) health effects calculations including the consideration of potential site specific mitigative actions (evacuation and shielding), and (4) modeling of multiple release segments. Three different sample problems are contained in this report to show how to use CHEM{_}MACCS. Three test problems are run to compare CHEM{_}MACCS and D2PC. The doses versus the downwind centerline distances from the source for the given doses are in very close agreement.

    Full Text Available Impalement injuries in children may be deeper and more complicated than anticipated. We experienced two cases of accidental impalement injuries, one was through the oral cavity and the other was to the neck. We review these cases and the management of these types of injuries. Case series. In case 1, a 20-month-old girl fell from the table with a toothbrush in her mouth. She was conscious, without any apparent neurologic or vascular injuries. Examination revealed a 2 mm laceration with a small hematoma in the right posterior pharyngeal wall. Contrast-enhanced computed tomography (CECT revealed an air tract penetrating between the mandibular ramus and cervical vertebrae, passing by the carotid sheath, and reaching under the skin of the right posterior neck. Surgical emphysema was extended from the pharynx to the mediastinum. In case 2, a 3-year-old girl fell while holding a pencil. Physical examination revealed a 5 mm laceration in front of her right ear lobe accompanied by a small hematoma. Her facial movement was asymmetric, and she could not close her right eye. CECT showed swelling of the right parotid gland with heterogeneous enhancement and free air just in front of the right carotid sheath, which suggested the object penetrated through the parotid gland. A diagnosis of peripheral facial nerve injury was made. Physicians need to be aware of the potentially life-threatening complications of impalement injuries in children, as well as the specific complications related to proximity to specific anatomic structures.

    2007-04-15

    Purpose: To assess multidetector computed tomography (MDCT) findings in facial trauma in adults who accidentally fall from heights. Material and Methods: Of the MDCT scans of 2413 cases requested by emergency-room physicians for suspected facial injury, 155 (age 15.3-76.7, mean 42.0 years; 134 male, 21 female) met the criteria of falling from heights. These were reviewed by two researchers by consensus. Results: Of these 155, 118 (104 male, 14 female) had 247 fractures, while 37 had no fracture. The fractures were classified into 13 categories, the zygomatic complex being the region most frequently involved. Mean falling height, known in 132 of 155 cases, was 5.7 m (range 0.4-25) in all, 6.0 m (0.4-25) in those suffering a fracture, and 5.0 m (range 0.4-13) in those without a fracture. Patients with Le Fort II, Le Fort III, or frontal bone fractures had fallen higher and frequently had associated skull base fractures, but with considerable overlap in falling heights. Zygomatic arch and nasal bone fractures rarely occurred solitarily. Conclusion: In a fall-from-height injury, nasal bone and zygomatic arch fractures indicate the presence of more severe fractures. Height cannot solely predict injury probability. Clear sinus sign is a valuable aid in assessing midface trauma in falls from heights. Keywords: CT; face; trauma.

    Full Text Available Ingestion of foreign bodies is not an uncommon occurrence, but most of them will pass through the gastrointestinal tract without consequences. Complication such as perforation is rare. We present a case of small bowel perforation secondary to the accidental ingestion of a chicken bone. The patient presented with abdominal pain, constipation and vomiting. Clinical examination confirmed generalized abdominal tenderness and rebound tenderness. Abdominal radiography showed multiple dilated loops of small bowel, and abdominal ultrasound (US showed inflammatory changes on small bowel loops, with free fluid and fluid collection around intestinal loops. The patient underwent an emergency laparotomy. Intra operative findings revealed diffuse fibro purulent peritonitis with abscess between central small bowels loops. At about 60 cm from Bauchini valve we found a perforation of ileum at the anti-mesenteric site caused by a sharp chicken wishbone. The patient was treated with resection of the ileum segment (10 cm and primary end-to-end anastomosis. Even that intestinal perforation by a foreign body is rare, physicians should consider possibility of intestinal perforation by a foreign body in the differential diagnosis of acute abdomen in patients presenting with abdominal pain.

    Accidental exposure to cold water environment is one of the most challenging situations in which hypothermia occurs. In the present work, we aim to characterise the energy balance of a human body subjected to such extreme environmental conditions. This study is carried out using a recently developed computational model and by setting boundary conditions needed to simulate the effect of cold surrounding environment. A major finding is the capacity of the body core regions to maintain their temperature high for a substantial amount of time, even under the most extreme environmental conditions. We also considered two disease states that highlight the spectrum of possible pathologies implicated in thermal regulation of the human body. These states are (i) cardiomyopathy, which affects the operating capacity of the heart, and (ii) malnutrition, which directly impairs the body's ability to regulate heat exchange with the environment. We have found that cardiomyopathy has little influence on the thermal balance of the human body, whereas malnutrition has a profound negative effect on the thermal balance and leads to dramatic reduction in core temperature.

    Following initial signs of dural infection, or as prophylactic postoperative therapy, three cynomologus macaques were given an intramuscular or a subcutaneous injection of ceftriaxone dissolved in a 1% lidocaine diluent (CL). Two to 15 min later, all three monkeys experienced a long-lasting generalized apnoeic clonic convulsive seizure. The injected doses of lidocaine (0.7-2 mg/kg) were as low as 7-20-fold less than the experimental intravenous dosage (14.2 +/- 3.2 mg/kg) previously reported to induce seizure in healthy rhesus monkeys. Under different clinical conditions, the same three animals were either once (1 animal) or repeatedly given CL without any resultant neurological alterations. The monkeys had a cranial device implanted and two of them were craniotomized. This first report of accidental lidocaine-induced seizure in laboratory non-human primates following CL injection strongly suggests increased susceptibility when lidocaine administration is associated with central nervous system alteration. A novel hypothesis, the possible role of cytokine in lowering the lidocaine seizure threshold, is suggested.

    Child abuse, or nonaccidental trauma (NAT), is a major cause of pediatric morbidity and mortality, and is often unrecognized. Our hypothesis was that injuries due to accidental trauma (AT) and NAT are significantly different in incidence, injury, severity, and outcome, and are often unrecognized. Our aim was to carry out an examination of the differences between pediatric injuries due to AT and NAT regarding incidence, demographics, injury severity, and outcomes. A 4-year retrospective review of the Trauma Registry at Children's Medical Center Dallas, a large Level I pediatric trauma center, comparing incidence, age, race, trauma activation, intensive care unit (ICU) need, Injury Severity Score (ISS), and mortality between AT and NAT patients was carried out. There were 5948 admissions, 92.5% were AT and 7.5% were NAT victims. The NAT patients were younger (1.8 ± 3.3 years vs. 6.8 ± 4.2 years for AT patients; p trauma child. Copyright © 2015 Elsevier Inc.

    Non-accidental trauma (NAT) victims account for a significant percentage of our pediatric trauma population. We sought to better understand the injury patterns and outcomes of NAT victims who were treated at our level I pediatric trauma center. Trauma registry data were used to identify NAT victims between January 2008 and December 2012. Demographic data, injury severity, hospital course, and outcomes were evaluated. One hundred and eighty-eight cases of suspected NAT were identified. Children were mostly male and white. The median age was 1.1 years; the median Injury Severity Score was 9. Traumatic brain injuries, lower extremity fractures, and skull fractures were the most common injuries. Twenty-seven per cent required medical procedures; most were performed by orthopedic surgery. Twenty-four per cent required admission to the pediatric intensive care unit. The median length of stay was two days. The mortality rate was 9.6 per cent. We generated a hot spot map of our catchment area and identified areas of our state where NAT occurs at increased rates. NAT victims sustain significant morbidity and mortality. Due to the severity of injuries, pediatric trauma surgeons should be involved in the evaluation and management of these children. Much work is needed to prevent the death and disability incurred by victims of child abuse.

    Full Text Available Fish bone is the most common foreign body that is ingested accidentally and can be caused gastrointestinal complications such as perforation, abstraction, and abscess. We describe a 75-year-old man who suffered from constipation, diarrhea, and fever and chills for 3 months. He had mild tenderness in hypogasteric region and also mild tenderness and swelling on anterior rectal wall and prostate upon clinical examination. The abdominal and pelvic sonography and CT scan findings suggested existence of abscess in the space of between bladder and rectum. The patient underwent laparotomy to drainage the pelvic abscess. The surgeon found a 6-cm fish bone which was embedded in the abscess. The presented case indicated the importance of accidental fish bone ingestion and its possible complications. In addition, the patients with abdominal pain, GI bleeding, and fever of unknown origin living in the seaside regions, the wandering fish bone as a differential diagnosis should be kept in mind.

    Recent experimental research has either focused on the role of accidental hypothermia as part of the lethal triad after trauma or tried to elucidate the effects of therapeutically induced hypothermia on the posttraumatic course. Induced hypothermia seems to reduce the mortality in experimental models of trauma-haemorrhage. As potential mechanisms, a decrease of cellular metabolism, beneficial effects on haemodynamic function and an attenuation of the inflammatory response have been described. However, negative side effects of hypothermia have to be considered, such as impairment of the coagulatory function and immunosuppressive effects. Furthermore, the optimal strategy for the induction of hypothermia (magnitude, duration, timing, cooling rate, etc.) and subsequent rewarming remains unclear. Nevertheless, this piece of information is essential before considering hypothermia as a treatment strategy for severely injured patients. This review aims to elaborate the differences between accidental and induced hypothermia and to summarize the current knowledge of the potential therapeutic use of induced hypothermia suggested in porcine models of trauma-haemorrhage.

    This paper surveys various models for estimating indoor concentration as a function of outdoor concentration in the event of an accidental release or chemical attack involving toxic substances. It is essential to know indoor concentration in order to estimate the effectiveness of shelter in place as a protective measure. Several models—deposition, one-sink, sink-diffusion and two-sink—were considered. These models can be derived from a general model by making different assumptions. The models...

    Plasma exposure was followed by the oxidation of alloys at 1000°C accomplishing the first test of these new materials both in a plasma environment and under accidental conditions. Compared to pure tungsten, smart alloys featured the 3-fold suppression of oxidation. Plasma exposure did not affect the oxidation resistance of smart alloys. At the same time, the self-passivation of the protective layer did not occur, calling for further optimization of alloys.

    Accidental freezing of vaccines is a growing threat and a real risk for national immunization programs when the potency of many vaccines can be compromised if these are exposed to sub-zero temperatures in the cold chain. In Tunisia, this issue is compounded by using sub-standard domestic cold chain equipment instead of equipping the program with medical refrigerators designed specifically for storing vaccines and temperature sensitive pharmaceuticals. Against this backdrop, this paper presents the findings of a demonstration project conducted in Tunisia in 2012 that tested the impact of introducing several freeze prevention solutions to mitigate the risk of accidental freezing of vaccines. The main finding is that, despite the continued use of underperforming domestic refrigerators, continuous temperature monitoring using new technologies combined with other technological interventions significantly reduced the prevalence of accidental exposure to freezing temperatures. These improvements were noticed for cold chain storage at regional, district and health center levels, and during the transport legs that were part of the demonstration conducted in the regions of Kasserine in the South-Eastern part of Tunisia. Subsequent to introducing these freeze prevention solutions, the incidence of freeze alarms was reduced and the percent of time the temperatures dropped below the 2 °C recommended threshold. The incidence of freeze alarms at health center level was reduced by 40%. Lastly, the solutions implemented reduced risk of freezing during transport from 13.8% to 1.7%. Although the solution implemented is not optimal in the longer term because domestic refrigerators are used extensively in district stores and health centers, the risk of accidental freezing is significantly reduced by introducing the practice of continuous temperature monitoring as a standard. The management of the cold chain equipment was strengthened as a result which helps protect the potency of

Youth versus adult “weightlifting” injuries presenting to united states emergency rooms: accidental versus nonaccidental injury mechanisms. J Strength Cond Res 23(7): 2054–2060, 2009—Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for “Weightlifting.” Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as “accidental” if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4, 111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p sprains and strains relative to younger age categories (p sprains and muscle strains than adults. The majority of youth resistance training injuries are the result of accidents that are potentially preventable with increased supervision and stricter safety guidelines. PMID:19855330

    A crossbow is a bow that shoots an arrow when a gun-like trigger is pulled. Deaths caused by accidental crossbow shootings are extremely rare. Here we describe an autopsy case of a penetrating wound to the left cerebral hemisphere caused by an accidental shooting with a crossbow. A man in his early 60s who lived with his wife and had used crossbows for 20 years as his hobby was found one early morning in the shed of his house, collapsed and bleeding from the head and neck. He was taken to a hospital and died after approximately 3 days of conservative treatment. At autopsy, a penetrating wound between the upper part of the left anterior neck and the left frontoparietal region was evident. Traumatic intracerebral hematoma was observed in the left frontal lobe, and severe traumatic subarachnoid hemorrhage was present throughout the brain. Cerebral contusion and hematoma without any organization were noted around the penetration. The cause of death was determined to be cerebral contusion and intracerebral hematoma due to the penetrating wound by the crossbow arrow. He was probably trying to load an arrow into the crossbow by placing it on the floor, pointing upward, and made a mistake in its operation that resulted in the shooting of the arrow. This case is unique because it was a rare accidental death caused by a crossbow arrow, and a detailed histopathological examination was performed.

    We present the main findings of the 5th National Audit Project on accidental awareness during general anaesthesia. Incidences were estimated using reports of accidental awareness as the numerator, and a parallel national anaesthetic activity survey to provide denominator data. The incidence of certain/probable and possible accidental awareness cases was ~1:19 600 anaesthetics (95% CI 1:16 700-23 450). However, there was considerable variation across subtypes of techniques or subspecialties. The incidence with neuromuscular blockade was ~1:8200 (1:7030-9700), and without it was ~1:135 900 (1:78 600-299 000). The cases of accidental awareness during general anaesthesia reported to 5th National Audit Project were overwhelmingly cases of unintended awareness during neuromuscular blockade. The incidence of accidental awareness during caesarean section was ~1:670 (1:380-1300). Two thirds (82, 66%) of cases of accidental awareness experiences arose in the dynamic phases of anaesthesia, namely induction of and emergence from anaesthesia. During induction of anaesthesia, contributory factors included: use of thiopental; rapid sequence induction; obesity; difficult airway management; neuromuscular blockade; and interruptions of anaesthetic delivery during movement from anaesthetic room to theatre. During emergence from anaesthesia, residual paralysis was perceived by patients as accidental awareness, and commonly related to a failure to ensure full return of motor capacity. One third (43, 33%) of accidental awareness events arose during the maintenance phase of anaesthesia, most due to problems at induction or towards the end of anaesthesia. Factors increasing the risk of accidental awareness included: female sex; age (younger adults, but not children); obesity; anaesthetist seniority (junior trainees); previous awareness; out-of-hours operating; emergencies; type of surgery (obstetric, cardiac, thoracic); and use of neuromuscular blockade. The following factors were

    There are concerns that the reported association of ambient fine particulate matter (PM2.5) with mortality might be a mixture of PM2.5 and weather conditions. We evaluated the effects of extreme weather conditions and weather types on mortality as well as their interactions with PM2.5 concentrations in a time series study. Daily non-accidental deaths, individual demographic information, daily average PM2.5 concentrations and meteorological data between 2012 and 2014 were obtained from Shanghai, China. Days with extreme weather conditions were identified. Six synoptic weather types (SWTs) were generated. The generalized additive model was set up to link the mortality with PM2.5 and weather conditions. Parameter estimation was based on Bayesian methods using both the Jeffreys' prior and an informative normal prior in a sensitivity analysis. We estimate the percent increase in non-accidental mortality per 10 μg/m3 increase in PM2.5 concentration and constructed corresponding 95% credible interval (CrI). In total, 336,379 non-accidental deaths occurred during the study period. Average daily deaths were 307. The results indicated that per 10 μg/m3 increase in daily average PM2.5 concentration alone corresponded to 0.26-0.35% increase in daily non-accidental mortality in Shanghai. Statistically significant positive associations between PM2.5 and mortality were found for favorable SWTs when considering the interaction between PM2.5 and SWTs. The greatest effect was found in hot dry SWT (percent increase = 1.28, 95% CrI: 0.72, 1.83), followed by warm humid SWT (percent increase = 0.64, 95% CrI: 0.15, 1.13). The effect of PM2.5 on non-accidental mortality differed under specific extreme weather conditions and SWTs. Environmental policies and actions should take into account the interrelationship between the two hazardous exposures.

    Accidental exposure to blood and body fluids is a public health concern, especially among health workers and constitutes a risk of transmission of blood-borne viruses including HIV, hepatitis B virus and hepatitis C virus. The objective of this study was to determine the frequency and the post exposure management of accidental exposures to blood and body fluid among health workers in the Yaoundé University Teaching Hospital. It was a cross-sectional hospital-based study conducted from the 1st to the 30th of September 2013. Self-administered questionnaires to health workers were used to collect data on self-reported accidents, circumstances and post-exposure management. Their knowledge on accidental exposure to blood was also assessed. Data were entered and analyzed using Epi Info software version 3.5.4. Descriptive analysis was performed to measure the importance of AEB and to evaluate the risk of contamination. One hundred and fifty health workers were interviewed among which 36.7 % reported having been exposed to blood and body fluid at least once in the preceding 3 months. Splash was the most reported injury (in 60.3 % of cases), followed by needle stick (28.7 %) and cuts (10.9 %). Moreover, 43.6 % of victims were not vaccinated against HBV, 7.3 % were not wearing gloves during the accident and 41 % of splash occurs on injured skin. The majority of victims belong to the surgical Department [20 %, p = 0.2310]. None of these injuries had been reported in the registry of accidental exposure to blood. There is a high rate of accidental exposure to blood and body fluid in the daily hospital routine. Preventives measures, including wearing of protective equipment's during care and vaccination against HBV are not systematically done among health workers. Health institution should develop and provide standard operating procedures targeting surveillance of occupational risks, staff training, and supervision.

    The recent detection of the cosmic microwave background polarimeter experiment BICEP2 of tensor fluctuations in the B-mode power spectrum basically excludes all plausible axion models where its decay constant is above 10{sup 13} GeV. Moreover, there are strong theoretical, astrophysical, and cosmological motivations for models involving, in addition to the axion, also axion-like particles (ALPs), with decay constants in the intermediate scale range, between 10{sup 9} GeV and 10{sup 13} GeV. Here, we present a general analysis of models with an axion and further ALPs and derive bounds on the relative size of the axion and ALP photon (and electron) coupling. We discuss what we can learn from measurements of the axion and ALP photon couplings about the fundamental parameters of the underlying ultraviolet completion of the theory. For the latter we consider extensions of the Standard Model in which the axion and the ALP(s) appear as pseudo Nambu-Goldstone bosons from the breaking of global chiral U(1) (Peccei-Quinn (PQ)) symmetries, occuring accidentally as low energy remnants from exact discrete symmetries. In such models, the axion and the further ALP are protected from disastrous explicit symmetry breaking effects due to Planck-scale suppressed operators. The scenarios considered exploit heavy right handed neutrinos getting their mass via PQ symmetry breaking and thus explain the small mass of the active neutrinos via a seesaw relation between the electroweak and an intermediate PQ symmetry breaking scale. We show some models that can accommodate simultaneously an axion dark matter candidate, an ALP explaining the anomalous transparency of the universe for γ-rays, and an ALP explaining the recently reported 3.55 keV gamma line from galaxies and clusters of galaxies, if the respective decay constants are of intermediate scale.

    Full Text Available Artificial reefs are considered one of the alternative methods in fisheries management, used in order to enhance stocks and marine biodiversity in general. A number of biotic and abiotic parameters influence the fouling communities’ formation on artificial reefs through complex interactions. In order to understand how epibiotic or fouling communities progress through time, it is important to study these communities in mature artificial reefs, especially those that have been around for many decades, or in some cases, millennia. This study was conducted on the coral and other fouling organisms of two accidental artificial reefs (40 to 70 year-old shipwrecks in Cyprus (Levantine Sea. The thermal and nutrient annual regime of the study sites were characterized by processing satellite data. The results indicate that the wrecks are normally under warm and oligotrophic conditions. Percentage coverage of corals and other organisms on the wrecks was calculated (image-analysis software on photos taken in 2010 (two wrecks and again in 2016 (one wreck of the fouling communities. Sponges were the organisms with the highest percent cover (~27% at the two wrecks. Four scleractinian coral species were found (7%–19% total coral cover. The oldest wreck, which has well-developed coral communities, was revisited during fieldwork in a near-by area in 2016. Only two major benthic categories (dead coral and macro algae changed significantly between sampling periods. Given the actual policies to sink wrecks to create artificial reefs and the diverse environmental conditions in different areas that will inevitably influence fouling, it is important to carry out studies relating to mature artificial reefs/wrecks in order to be able to assess the ecological effectiveness of longstanding artificial reefs.

  20. Assessment of methodologies for analysis of the dungeness B accidental aircraft crash risk.

    The Health and Safety Executive (HSE) has requested Sandia National Laboratories (SNL) to review the aircraft crash methodology for nuclear facilities that are being used in the United Kingdom (UK). The scope of the work included a review of one method utilized in the UK for assessing the potential for accidental airplane crashes into nuclear facilities (Task 1) and a comparison of the UK methodology against similar International Atomic Energy Agency (IAEA), United States (US) Department of Energy (DOE), and the US Nuclear Regulatory Commission (NRC) methods (Task 2). Based on the conclusions from Tasks 1 and 2, an additional Task 3 would provide an assessment of a site-specific crash frequency for the Dungeness B facility using one of the other methodologies. This report documents the results of Task 2. The comparison of the different methods was performed for the three primary contributors to aircraft crash risk at the Dungeness B site: airfield related crashes, crashes below airways, and background crashes. The methods and data specified in each methodology were compared for each of these risk contributors, differences in the methodologies were identified, and the importance of these differences was qualitatively and quantitatively assessed. The bases for each of the methods and the data used were considered in this assessment process. A comparison of the treatment of the consequences of the aircraft crashes was not included in this assessment because the frequency of crashes into critical structures is currently low based on the existing Dungeness B assessment. Although the comparison found substantial differences between the UK and the three alternative methodologies (IAEA, NRC, and DOE) this assessment concludes that use of any of these alternative methodologies would not change the conclusions reached for the Dungeness B site. Performance of Task 3 is thus not recommended.

    Limited joint mobility syndrome (LJMS) appears exclusively in both type 1 and type 2 diabetic patients. It is characterized by a limited range of digital motion, with involvement of small joints of the hands. It initially affects the proximal interphalangeal joints, followed by wrists, elbows, shoulders, knees, and axial skeleton. The diagnosis can be made by the simple "prayer sign" test. The objective was to study the prevalence of diabetic patients with LJMS, and to evaluate the association between LJMS and metabolic control, and the risk of accidental falls. A cross-sectional study was conducted in the San Fernando II Health Centre, Madrid (suburbs). The sample consisted of 184 patients with a diagnosis of diabetes of over 5 years from November to March, 2013. The prayer sign was used to define which patients had LJMS. Fall risk was determined using the Timed Up & Go test. A total of 99 patients (53.8%) (95% CI 46.6 to 61) had a positive prayer sign. No statistically significant relationship was found with HbA1c, but there was an association with the Timed Up & Go test (P<.001) (95% CI 1.173 to 1.611). The patients with LJMS had a moderate risk of falls compared with those without LJMS, which was of low risk. The prevalence of LJMS is high. This is the first study that shows a relationship between LJMS and the risk of falls in diabetic patients. Copyright © 2013 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

    This study applied the American Meteorological Society and Environmental Protection Agency Regulatory Model (AERMOD) to assess the risk caused by an accidental release and dispersion of the toxic chemical benzene in the vicinity of a highly populated urban area. The modeling domain encompasses the Korean megacity of Ulsan, which includes two national industrial complexes and is characterized by a complex coastal terrain. Multiple AERMOD simulations were conducted for an assumed emission scenario using background wind data from August between 2009 and 2013. The series of experiments produced the spatial accident probability patterns for different concentration levels during daytime and nighttime scenarios based on the corresponding dominant wind patterns. This study further quantifies the potential accident risk based on the number of affected individuals by combining the accident probability with the indoor and outdoor population estimates. The chemical gas dispersion characteristics depend on various local meteorological conditions, such as the land-sea breeze direction, which alternates between daytime and nighttime, and the atmospheric stability. The results reveal that benzene dispersion affects a much larger area during the nighttime owing to the presence of a nocturnal stable boundary layer with significant temperature stratification. The affected area is smaller during the daytime owing to decreased stability and enhanced vertical mixing in the boundary layer. The results include a high degree of uncertainty during the nighttime owing to weak wind speeds and the lack of a prevailing wind direction, which impact the vulnerable area. However, vulnerable areas are more effectively identified during the daytime, when more consistent meteorological conditions exist. However, the potential risk becomes much lower during the nighttime owing to a substantial reduction of the outdoor population.

    Following an accidental human exposure to a vesicating agent, plasma samples were analyzed for specific biomarkers of sulfur mustard. One individual suffered chemical burns over 6.5% of the body surface area and required hospitalization; the second individual developed a single, small blister. Plasma specimens from both individuals were examined using two different assays. The first assay targeted sulfur mustard adducts to cysteine-34 of albumin using affinity chromatography, enzyme digestion, and analysis of the alkylated peptide fragment using liquid chromatography-tandem mass spectrometry. The second assay targeted alkylation sites of glutamic and aspartic acids of plasma proteins. Following precipitation of plasma proteins, the sulfur mustard adducts were cleaved from the protein using base, derivatized, and analyzed using gas chromatography-mass spectrometry. Samples obtained over a 42-day period from the individual requiring hospitalization produced positive results for sulfur mustard adducts using both assays. Observed levels of the sulfur mustard biomarker decreased by approximately 75% between days 2 and 42 for both assays. Samples obtained over a six-day period from the individual with a single, small blister produced positive results for the albumin adduct assay. Observed levels were much lower than levels from the hospitalized patient. Blood samples from suspected human exposures to sulfur mustard have only rarely been made available for analysis by sensitive and specific laboratory assays. The data presented here add significantly to the small database of information that currently exists on human biomarkers of sulfur mustard exposure, linking a well-documented exposure event with levels of plasma protein adducts.

    A scientist in our laboratory was accidentally infected while working with Z5463, a Neisseria meningitidis serogroup A strain. She developed severe symptoms (fever, meningism, purpuric lesions) that fortunately evolved with antibiotic treatment to complete recovery. Pulse-field gel electrophoresis confirmed that the isolate obtained from the blood culture (Z5463BC) was identical to Z5463, more precisely to a fourth subculture of this strain used the week before the contamination (Z5463PI). In order to get some insights into genomic modifications that can occur in vivo, we sequenced these three isolates. All the strains contained a mutated mutS allele and therefore displayed an hypermutator phenotype, consistent with the high number of mutations (SNP, Single Nucleotide Polymorphism) detected in the three strains. By comparing the number of SNP in all three isolates and knowing the number of passages between Z5463 and Z5463PI, we concluded that around 25 bacterial divisions occurred in the human body. As expected, the in vivo passage is responsible for several modifications of phase variable genes. This genomic study has been completed by transcriptomic and phenotypic studies, showing that the blood strain used a different haemoglobin-linked iron receptor (HpuA/B) than the parental strains (HmbR). Different pilin variants were found after the in vivo passage, which expressed different properties of adhesion. Furthermore the deletion of one gene involved in LOS biosynthesis (lgtB) results in Z5463BC expressing a different LOS than the L9 immunotype of Z2491. The in vivo passage, despite the small numbers of divisions, permits the selection of numerous genomic modifications that may account for the high capacity of the strain to disseminate.

  7. Surgical Management of Accidentally Displaced Mandibular Third Molar into the Pterygomandibular Space: A Case Report

    Full Text Available Surgical removal of the mandibular third molar is a regular surgical procedure in dental clinics, and like all operations, it may have some complications, such as infection, bleeding, nerve injuries, trismus and so on. An accidentally displaced lower third molar is a relatively rare complication, but may cause severe tissue injury and medicolegal problems. As few papers and cases have been published on this topic, we report this case to remind dentists on ways to prevent and manage this complication. The patient, a 28-year-old male, had his right lower mandibular third molar extraction in January 2006. The dentist resected the crown and attempted to remove the root but found that it had suddenly disappeared from the socket. Assuming that the root had been suctioned out he closed the wound. The patient was not followed up regularly because he studied abroad. About 3 months later, the patient felt a foreign body sensation over his right throat, and visited a local hospital in Australia. He was told after a computed tomography (CT scan that there was a root-like radio-opaque image in the pterygomandibular space. The patient came to our hospital for further examination and management in June 2006. We rechecked with both Panorex and CT and confirmed the location of the displaced root. Surgery for retrieving the displaced root was performed under general anesthesia by conventional method without difficulty, and the wound healed uneventfully except for a temporary numbness of the right tongue. This case reminds us that the best way to prevent a displaced mandibular third molar is to evaluate the condition of the tooth carefully preoperatively, select adequate instruments and technique, and take good care during extraction. If an accident does occur, dentists should decide whether to retrieve it immediately by themselves or refer the case to an oral and maxillofacial surgeon, and should not try to remove the displaced root without proper assurance

    ASTRID is a technological demonstrator of Sodium cooled Fast Reactor (SFR) under development. The conceptual design studies are being conducted in accordance with the Generation IV reactor objectives, particularly in terms of improving safety. For the hypothetical events, belonging to the accidental category "severe accident prevention situations" having a very low frequency of occurrence, the safety demonstration is no more based on a deterministic demonstration with conservative assumptions on models and parameters but on a "Best-Estimate Plus Uncertainty" (BEPU) approach. This BEPU approach ispresented in this paper for an Unprotected Loss-of-Flow (ULOF) event. The Best-Estimate (BE) analysis of this ULOFt ransient is performed with the CATHARE2 code, which is the French reference system code for SFR applications. The objective of the BEPU analysis is twofold: first evaluate the safety margin to sodium boiling in taking into account the uncertainties on the input parameters of the CATHARE2 code (twenty-two uncertain input parameters have been identified, which can be classified into five groups: reactor power, accident management, pumps characteristics, reactivity coefficients, thermal parameters and head losses); secondly quantify the contribution of each input uncertainty to the overall uncertainty of the safety margins, in order to refocusing R&D efforts on the most influential factors. This paper focuses on the methodological aspects of the evaluation of the safety margin. At least for the preliminary phase of the project (conceptual design), a probabilistic criterion has been fixed in the context of this BEPU analysis; this criterion is the value of the margin to sodium boiling, which has a probability 95% to be exceeded, obtained with a confidence level of 95% (i.e. the M5,95percentile of the margin distribution). This paper presents two methods used to assess this percentile: the Wilks method and the Bootstrap method ; the effectiveness of the two methods

    Despite calls for greater physician leadership, few medical schools, and graduate medical education programs provide explicit training on the knowledge, skills, and attitudes necessary to be an effective physician leader. Rather, most leaders develop through what has been labeled "accidental leadership." A survey was conducted at Walter Reed to define the current status of leadership development and determine what learners and faculty perceived as key components of a leadership curriculum. A branching survey was developed for residents and faculty to assess the perceived need for a graduate medical education leadership curriculum. The questionnaire was designed using survey best practices and established validity through subject matter expert reviews and cognitive interviewing. The survey instrument assessed the presence of a current leadership curriculum being conducted by each department, the perceived need for a leadership curriculum for physician leaders, the topics that needed to be included, and the format and timing of the curriculum. Administered using an online/web-based survey format, all 2,041 house staff and educators at Walter Reed were invited to participate in the survey. Descriptive statistics were conducted using SPSS (version 22). The survey response rate was 20.6% (421/2,041). Only 17% (63/266) of respondents stated that their program had a formal leadership curriculum. Trainees ranked their current leadership abilities as slightly better than moderately effective (3.22 on a 5-point effectiveness scale). Trainee and faculty availability were ranked as the most likely barrier to implementation. Topics considered significantly important (on a 5-point effectiveness scale) were conflict resolution (4.1), how to motivate a subordinate (4.0), and how to implement change (4.0). Respondents ranked the following strategies highest in perceived effectiveness on a 5-point scale (with 3 representing moderate effectiveness): leadership case studies (3.3) and

    Dispersion modeling of accidental releases of toxic gases - Comparison of the models and their utility for the fire brigades. Sirma Stenzel, Kathrin Baumann-Stanzer In the case of accidental release of hazardous gases in the atmosphere, the emergency responders need a reliable and fast tool to assess the possible consequences and apply the optimal countermeasures. For hazard prediction and simulation of the hazard zones a number of air dispersion models are available. The most model packages (commercial or free of charge) include a chemical database, an intuitive graphical user interface (GUI) and automated graphical output for display the results, they are easy to use and can operate fast and effective during stress situations. The models are designed especially for analyzing different accidental toxic release scenarios ("worst-case scenarios"), preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management. There are also possibilities for model direct coupling to automatic meteorological stations, in order to avoid uncertainties in the model output due to insufficient or incorrect meteorological data. Another key problem in coping with accidental toxic release is the relative width spectrum of regulations and values, like IDLH, ERPG, AEGL, MAK etc. and the different criteria for their application. Since the particulate emergency responders and organizations require for their purposes unequal regulations and values, it is quite difficult to predict the individual hazard areas. There are a quite number of research studies and investigations coping with the problem, anyway the end decision is up to the authorities. The research project RETOMOD (reference scenarios calculations for toxic gas releases - model systems and their utility for the fire brigade) was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG) in cooperation with the Vienna fire brigade, OMV Refining & Marketing GmbH and

    Full Text Available Objective  To observe the influences of regional citrate or systemic heparin anticoagulation on acid-base balance, coagulation, electrolytes, serum creatinine, alanine aminotransferase (ALT and cardiac index (CI during continuous renal replacement therapy (CRRT rewarming in accidental hypothermia dogs. Methods  Nineteen adult beagles were given abdominal trauma coupled with deep hypothermia [(28±0.5℃] induced by seawater immersion for establishing animal model of trauma. According to rewarming ways, the animal models were randomly divided into three groups, comparison group (warm bath rewarming, n=5, CRRT rewarming-systemic heparin anticoagulation group (heparin anticoagulation group, n=7 and CRRT rewarming-regional citrate anticoagulation group (citrate anticoagulation group, n=7. During the rewarming routine blood examination was performed, and blood chemistry, coagulation function, blood gas and hemodynamic status were assayed, at the same time the mortality was recorded. Results  During the rewarming, the mortality was 14.3% (1/7 in heparin anticoagulation group, 40.0% (2/5 in warm bath group and 0 in regional citrate anticoagulation group. Blood temperature in creased to 38℃, the heparin anticoagulation group showed a significant decrease of platelet compared with citrate anticoagulation group and comparison group (P0.05. Conclusions  CRRT plus warm bath rewarming have better effect on improving metabolic acidosis than warm bath rewarming alone in accidental hypothermia dogs. In comparison with systemic heparin anticoagulation, regional citrate anticoagulation has smaller influences on coagulation system and platelet when CRRT rewarming performed in accidental hypothermia dogs.

    As part of the 5th National Audit Project of the Royal College of Anaesthetists and the Association of Anaesthetists of Great Britain and Ireland concerning accidental awareness during general anaesthesia, we issued a questionnaire to every consultant anaesthetist in each of 46 public hospitals in Ireland, represented by 41 local co-ordinators. The survey ascertained the number of new cases of accidental awareness becoming known to them for patients under their care or supervision for a calendar year, as well as their career experience. Consultants from all hospitals responded, with an individual response rate of 87% (299 anaesthetists). There were eight new cases of accidental awareness that became known to consultants in 2011; an estimated incidence of 1:23 366. Two out of the eight cases (25%) occurred at or after induction of anaesthesia, but before surgery; four cases (50%) occurred during surgery; and two cases (25%) occurred after surgery was complete, but before full emergence. Four cases were associated with pain or distress (50%), one after an experience at induction and three after experiences during surgery. There were no formal complaints or legal actions that arose in 2011 related to awareness. Depth of anaesthesia monitoring was reported to be available in 33 (80%) departments, and was used by 184 consultants (62%), 18 (6%) routinely. None of the 46 hospitals had a policy to prevent or manage awareness. Similar to the results of a larger survey in the UK, the disparity between the incidence of awareness as known to anaesthetists and that reported in trials warrants explanation. Compared with UK practice, there appears to be greater use of depth of anaesthesia monitoring in Ireland, although this is still infrequent. © 2014 The Association of Anaesthetists of Great Britain and Ireland.

    To study the relationship between daily temperature and non-accidental deaths in four districts of Jinan, and to investigate the impact of temperature on cause-specific mortality. Data on daily mortality of the four districts (Shizhong, Huaiyin, Tianqiao, Lixia) as well as data related to meteorology and air pollution index were collected from January 1, 2008 to December 31, 2012. Distributed lag non-linear model (DLNM) was then used to assess the effects of temperature on all non-accidental deaths and deaths caused by cardiovascular diseases (CVD), respiratory diseases (RD), digestive diseases, urinary diseases, and also subcategories to hypertension, ischemic heart diseases (IHD), acute myocardial infarction (AMI), cerebro-vascular diseases (CBD) and chronic lower respiratory diseases. A W-shaped relationship was noticed between daily average temperature and non-accidental deaths. The effect of low temperature last for more than 30 days, much longer than that of high temperature, in which presented a harvesting effect less than 5 days. As to the cause-specific mortality, short-term heat effects were seen in CVD and RD as well as related subgroups as IHD, CBD and AMI, with RRs at lag 0 as 1.12 (95%CI:1.07-1.17), 1.06 (95% CI:1.02-1.31), 1.08 (95% CI:1.003-1.16), 1.10 (95% CI:1.02-1.20) and 1.13 (95% CI: 1.003-1.26). Relatively higher RRs were seen in urinary diseases and hypertension under extremely high temperature, reaching as high as 2.30 (95%CI:1.18-4.51) and 1.65 (95%CI:1.02-2.69). Cold weather presented a delayed effect for 30 days, with cumulative RRs as 1.51 (95%CI:1.42-1.60), 1.90 (95%CI:1.64-2.20), 2.12 (95%CI:1.67-2.69), 1.48 (95%CI:1.08-2.03), 1.60 (95%CI:1.46-1.75), 1.40 (95%CI:1.26-1.55), 1.68 (95%CI:1.45-1.95) for CVD, RD, chronic lower respiratory diseases, hypertension,IHD, CBD and AMI, on sequence. A relationship was seen between daily temperature and non-accidental deaths as well as cause-specific mortality. Either high or low temperature seemed

    The evidence to guide therapy in pediatric traumatic brain injury is lacking, including insight into the intracranial pressure/cerebral perfusion pressure thresholds in abusive head trauma. We examined intracranial pressure/cerebral perfusion pressure thresholds and indices of intracranial pressure and cerebral perfusion pressure burden in relationship with outcome in severe traumatic brain injury and in accidental and abusive head trauma cohorts. A prospective observational study. PICU in a tertiary children's hospital. Children less than18 years old admitted to a PICU with severe traumatic brain injury and who had intracranial pressure monitoring. None. A pediatric traumatic brain injury database was interrogated with 85 patients (18 abusive head trauma) enrolled. Hourly intracranial pressure and cerebral perfusion pressure (in mm Hg) were collated and compared with various thresholds. C-statistics for intracranial pressure and cerebral perfusion pressure data in the entire population were determined. Intracranial hypertension and cerebral hypoperfusion indices were formulated based on the number of hours with intracranial pressure more than 20 mm Hg and cerebral perfusion pressure less than 50 mm Hg, respectively. A secondary analysis was performed on accidental and abusive head trauma cohorts. All of these were compared with dichotomized 6-month Glasgow Outcome Scale scores. The models with the number of hours with intracranial pressure more than 20 mm Hg (C = 0.641; 95% CI, 0.523-0.762) and cerebral perfusion pressure less than 45 mm Hg (C = 0.702; 95% CI, 0.586-0.805) had the best fits to discriminate outcome. Two factors were independently associated with a poor outcome, the number of hours with intracranial pressure more than 20 mm Hg and abusive head trauma (odds ratio = 5.101; 95% CI, 1.571-16.563). As the number of hours with intracranial pressure more than 20 mm Hg increases by 1, the odds of a poor outcome increased by 4.6% (odds ratio = 1

    2014-07-01

    This article considers how the 'accidental logics' of political settlements for the English National Health Service (NHS) and the Medicare and Medicaid programmes in the United States have resulted in different institutional arrangements and different implicit social contracts for rationing, which we define to be the denial of health care that is beneficial but is deemed to be too costly. This article argues that rationing is designed into the English NHS and designed out of US Medicare; and compares rationing for the elderly in the United States and in England for acute care, care at the end of life, and chronic care.

No obstante, ya se han realizado primeras miradas en este sentido, presentando la siguiente investigación en personas con accidente cerebrovascular, como un análisis preliminar experimental; que más que brindar datos definitorios, permita a la vez, abrir nuevos caminos hacia la búsqueda de la multideterminación de los procesos patológicos. Con el objetivo central de determinar factores psicológicos de riesgo para la aparición de los accidentes cerebrovasculares, se establecieron dos grupos de estudio y testigo, a los cuales se le aplicaron el test de depresión Zung-Conde, el IDARE, el cuestionario de conductas de enfrentamiento y el examen neuropsicológico de Anne-Lise Crhistensen. Se pudo definir la existencia de factores más relacionados con características personológicas, factores externos fundamentalmente provenientes del medio y factores producto de esta interacción como lo constituyen el estrés y la ansiedad.

A pesar de esto, es de gran utilidad conocer la incidencia de estos accidentes, pues son de gran importancia por las pérdidas económicas que pueden causar en el sector pecuario. Los accidentes por serpientes venenosas, tanto de la familia Viperidae como Elapidae, en caballos y ganado vacuno son frecuentes en muchos lugares del mundo, debido al aumento en la destinación de las tierras para la actividad ganadera. Colombia no es ajena a ello; sin embargo, el registro de este tipo de accidentalidad es muy bajo. En los diferentes reportes de accidentes ofídicos en animales, se ha observado que las principales manifestaciones sistémicas están caracterizadas por complicaciones cardiacas, hemodinámicas y neurotóxicas. Igualmente, se observan efectos locales, los cuales se caracterizan por presencia de hemorragias locales, edema y necrosis. El tratamiento específico utilizado en los accidentes por serpientes es la seroterapia, que consta de inmunoglobulinas G (Sueros IgG completas o fraccionadas (Faboterápicos Fab o Fab2, específicas para un género o especie.

  15. Normal neurologic and developmental outcome after an accidental intravenous infusion of expressed breast milk in a neonate.

    2012-02-03

    Here we describe a premature male infant who was accidentally given 10 mL of expressed breast milk intravenously over a 3.5-hour period. Having survived this event with supportive care, this boy was attending regular school with no obvious neurologic or learning difficulties at 6 years of age. In 1998, after a query on an e-mail discussion group for health care providers in neonatology (NICU-net), we were informed of 8 similar events that proved fatal in 3 infants. A root-cause analysis revealed that accidental intravenous administration of breast milk or formula can be avoided by the use of color-coded enteral-administration sets with Luer connections that are not compatible with intravenous cannulas. The addition of methylene blue to feeds, or bolus enteral feeds (instead of continuous gastric feedings), may also help prevent such errors. These cases show the value of gathering information about rare but important events through a neonatal network. In addition, they confirm that prevention of medical error should focus on faulty systems rather than faulty people.

    Full Text Available Certain environmental microorganisms can cause severe human infections, even in the absence of an obvious requirement for transition through an animal host for replication ("accidental virulence". To understand this process, we compared eleven isolate genomes of Burkholderia pseudomallei (Bp, a tropical soil microbe and causative agent of the human and animal disease melioidosis. We found evidence for the existence of several new genes in the Bp reference genome, identifying 282 novel genes supported by at least two independent lines of supporting evidence (mRNA transcripts, database homologs, and presence of ribosomal binding sites and 81 novel genes supported by all three lines. Within the Bp core genome, 211 genes exhibited significant levels of positive selection (4.5%, distributed across many cellular pathways including carbohydrate and secondary metabolism. Functional experiments revealed that certain positively selected genes might enhance mammalian virulence by interacting with host cellular pathways or utilizing host nutrients. Evolutionary modifications improving Bp environmental fitness may thus have indirectly facilitated the ability of Bp to colonize and survive in mammalian hosts. These findings improve our understanding of the pathogenesis of melioidosis, and establish Bp as a model system for studying the genetics of accidental virulence.

    Core social interaction behaviors were examined in young children 0-36 months of age who were hospitalized for accidental (n = 61) or inflicted (n = 64) traumatic brain injury (TBI) in comparison to typically developing children (n = 60). Responding to and initiating gaze and joint attention (JA) were evaluated during a semi-structured sequence of social interactions between the child and an examiner at 2 and 12 months after injury. The accidental TBI group established gaze less often and had an initial deficit initiating JA that resolved by the follow-up. Contrary to expectation, children with inflicted TBI did not have lower rates of social engagement than other groups. Responding to JA was more strongly related than initiating JA to measures of injury severity and to later cognitive and social outcomes. Compared to complicated-mild/moderate TBI, severe TBI in young children was associated with less responsiveness in social interactions and less favorable caregiver ratings of communication and social behavior. JA response, family resources, and group interacted to predict outcomes. Children with inflicted TBI who were less socially responsive and had lower levels of family resources had the least favorable outcomes. Low social responsiveness after TBI may be an early marker for later cognitive and adaptive behavior difficulties.

    The paper presents a case of medical malpractice during the test for phenylketonuria. The authors analyzed all documents collected in the course of the investigation of infant poisoning due to accidental administration of ninhydrin. The medical assessment was based on an extensive review of the case history, as well as on spectroscopy (FT-IR), chromatography and chemical analysis findings that allowed for confirming the presence of the toxic substance in the evidence material collected during the initial investigation. The obtained results confirmed the presence of ninhydrin in the tea cup and in the teaspoon, which were used to prepare the diagnostic medium. No ninhydrin was found in other investigated materials. The employment of routine research methods, including GC-MS, FT-IR and UV-VIS, allowed for detection and identification of the pure chemical form of ninhydrin, as well as its color complex with amino acids. The detailed case analysis, as well as the variability of extensive evidence material collected during the investigation allowed for determining the identity of persons responsible for accidental administration of the poisoning substance to the infant.

    The 10 MW high-temperature gas-cooled test module (HTR-10) is a graphite-moderated and helium-cooled pebble bed reactor prototype that was designed to demonstrate the technical and safety feasibility of this type of reactor project under normal and accidental conditions. In addition, one of the systems responsible for ensuring the safe operation of this type of reactor is the passive decay heat removal system (DHRS), which operates using passive heat removal processes. A demonstration of the heat removal capacity of the DHRS under accidental conditions was analyzed based on a benchmark problem for design-based accidents on an HTR-10, i.e., the pressurized loss of forced cooling (PLOFC) described in technical reports produced by the International Atomic Energy Agency. In fact, the HTR-10 is also a proof-of-concept reactor for the high-temperature gas-cooled reactor pebble-bed module (HTR-PM), which generates approximately 25 times more heat than the HTR-10, with a thermal power of 250 MW, thereby requiring a DHRS with a higher system capacity. Thus, because an HTR-10 is a prototype reactor for an HTR-PM, a scaling analysis of the heat transfer process from the reactor to the DHRS was carried out between the HTR-10 and HTR-PM systems to verify the distortions of scale and the differences between the main dimensionless numbers from the two projects.

  1. Final Report: Safety of Plasma Components and Aerosol Transport During Hard Disruptions and Accidental Energy Release in Fusion Reactor

    Energy Technology Data Exchange (ETDEWEB)

    Bourham, Mohamed A.; Gilligan, John G.

    1999-08-14

    Safety considerations in large future fusion reactors like ITER are important before licensing the reactor. Several scenarios are considered hazardous, which include safety of plasma-facing components during hard disruptions, high heat fluxes and thermal stresses during normal operation, accidental energy release, and aerosol formation and transport. Disruption events, in large tokamaks like ITER, are expected to produce local heat fluxes on plasma-facing components, which may exceed 100 GW/m{sup 2} over a period of about 0.1 ms. As a result, the surface temperature dramatically increases, which results in surface melting and vaporization, and produces thermal stresses and surface erosion. Plasma-facing components safety issues extends to cover a wide range of possible scenarios, including disruption severity and the impact of plasma-facing components on disruption parameters, accidental energy release and short/long term LOCA's, and formation of airborne particles by convective current transport during a LOVA (water/air ingress disruption) accident scenario. Study, and evaluation of, disruption-induced aerosol generation and mobilization is essential to characterize database on particulate formation and distribution for large future fusion tokamak reactor like ITER. In order to provide database relevant to ITER, the SIRENS electrothermal plasma facility at NCSU has been modified to closely simulate heat fluxes expected in ITER.

    The traces of emissions from the Fukushima-1 NPP in atmospheric aerosols of the Kola Peninsula near the Barents Sea coast were detected by radiation monitoring stations of the Murmansk Division of the Hydrometeorological Survey MDHMS in the end of March 2011. From the end of March 2011 until April 20, 131I, 134Cs, 132Te, 137Cs radioisotopes were observed in the atmospheric air. The major role was played by 131I isotope; its peak concentrations were (140-220)×10-6 Bq/m3, and it was recorded for several days (March 30-April 1), then radioactivity decreased. 134Cs, 132Te, and 137Cs isotopes were recorded episodically. The supply of radionuclides from accidental emissions into the atmosphere of the Kola Peninsula did not cause significant changes in gamma-radiation dose rates EDR. This value remained within the limits of the average long-term norm, and continued so during the following months 2011. Possible dry and humid precipitation of radionuclides within the water catchment area and in the marine basin did not influence on radioecological state in both coastal and off-shore parts of the Barents Sea. Short-lived isotopes as 131I, 134Cs, and 132Te, which might confidently indicate a trace from the Fukushima-1 NPP, have not been recorded in the samples. In 2011-1012 volumetric activity of 137Cs and 90Sr in water of the Barents Sea (section VI along the meridian 33° 30' N) varied in the range of 1.3-2.5 and 3.4-6.3 Bq/m3, respectively. Radioactive contamination of bottom sediments in the Barents Sea was very low. The specific activity of 137Cs varied from 1 to 8 Bq/kg, the activity of 90Sr did not exceed 4 Bq/kg. Investigations of macrophyte algae showed extremely low concentrations of artificial radionuclides. The specific activity of 137Cs in most samples was at the level of trace concentrations, from 0.2 to 1.5 Bq/kg of dry mass. The content of 90Sr in algae changed in the range of 0.4-4.1 Bq/kg of dry mass. In soft tissues of bivalves Mytilus edulis collected on

    To identify possible cases of occupational asthma and assess accidental skin and inhalation exposures to aliphatic diisocyanates. Seventy-three employees from two plants, manufacturing or producing aliphatic diisocyanates, were surveyed using a detailed respiratory history questionnaire with additional questions on accidental skin and inhalation exposures. Further reviews of medical records and interviews were used to determine whether any of 15 employees with questionable responses had developed occupational asthma. No cases of occupational asthma were identified. Nevertheless, many employees reported occasional accidental unprotected skin exposures and/or detecting the odor of 1,6-hexamethylene diisocyanate or isophorone diisocyanate. Consistent with a previous study, no cases of occupational asthma were identified from exposure to 1,6-hexamethylene diisocyanate, isophorone diisocyanate, methylene bis(4-cyclohexyl isocyanate), or their polyisocyanates even though many employees reported detection of odors (93%) or skin exposures (53%).

    A phenomenon of switching of the parasite in the food chain to an accidental host is commonly observed in nature. However, there is little available data concerning the morphological descriptions of parasites that passively get into the atypical hosts and are capable, at least to some degree, of somatic growth and development of reproductive structures. A morphological survey of Diplodiscus subclavatus (Pallas, 1760) adults isolated from a digestive tract of an accidental host, Viviparus contectus (Millet, 1813), was carried out. Diplodiscus subclavatus individuals identified in prosobranch snails were morphologically similar to adult forms of the parasite described from amphibians, typical final hosts in the life cycle of this paramphistomid. The observed forms of D. subclavatus had a fully developed reproductive system, sperm in the seminal vesicle and oocytes in the ovary. The number of eggs in the uterus ranged from 3 to 17. Our research indicates that D. subclavatus individuals reach the sexual maturity in the accidental, invertebrate hosts.

    The 5th National Audit Project of the Royal College of Anaesthetists and the Association of Anaesthetists of Great Britain and Ireland into accidental awareness during general anaesthesia yielded data related to psychological aspects from the patient, and the anaesthetist, perspectives; patients' experiences ranged from isolated auditory or tactile sensations to complete awareness. A striking finding was that 75% of experiences were for anaesthesia or at the time of report seemed beneficial. Quality of care before the event was judged good in 26%, poor in 39% and mixed in 31%. Three quarters of cases of accidental awareness during general anaesthesia (75%) were judged preventable. In 12% of cases of accidental awareness during general anaesthesia, care was judged good and the episode not preventable. The contributory and human factors in the genesis of the majority of cases of accidental awareness during general anaesthesia included medication, patient and education/training. The findings have implications for national guidance, institutional organisation and individual practice. The incidence of 'accidental awareness' during sedation (~1:15 000) was similar to that during general anaesthesia (~1:19 000). The project raises significant issues about information giving and consent for both sedation and anaesthesia. We propose a novel approach to describing sedation from the patient's perspective which could be used in communication and consent. Eight (6%) of the patients had resorted to legal action (12, 11%, to formal complaint) at the time of reporting. The 5th National Audit Project methodology provides a standardised template that might usefully inform the investigation of claims or serious incidents related to accidental awareness during general anaesthesia. © 2014 by the Royal College of Anaesthetists and the Association of Anaesthetists of Great Britain and Ireland.

Diseño: Estudio descriptivo, retrospectivo, de corte transversal. Institución: Instituto Nacional de Rehabilitación, Callao, Perú. Participantes: Pacientes amputados por accidente de trabajo. Intervenciones: Revisión de 1 290 historias clínicas de pacientes amputados, atendidos del 1 de enero del 2003 al 31 de diciembre del 2007, de los cuales 108 fueron por accidente de trabajo. Se determinó los años acumulados de vida productiva potencial perdidos, multiplicando la diferencia entre la edad de retiro y la edad al momento de dictaminarse el grado de invalidez permanente, por el porcentaje de la invalidez. Principales medidas de resultados: Años acumulados de vida productiva potencial perdidos. Resultados: El accidente de trabajo fue la causa en 8,4% de los amputados, que generaron 1 568,5 años acumulados de vida productiva potencial perdidos, con 14,5 años por cada caso. El nivel más frecuente fue debajo de rodilla, con 27,3%. La manufactura fue la actividad económica más frecuente, con 37,9%, y la forma de accidente fue el aprisionamiento o atrapamiento en 58,3%. El sexo masculino predominó, 98,2%. El 40,7% se encontró en el rango de 21 a 30 años de edad y 63,9% no realizará su labor habitual por su invalidez. Conclusiones: Los años acumulados de vida productiva potencial perdidos es un indicador de gran utilidad para complementar la evaluación de los accidentes de trabajo en la invalidez residual, porque considera la edad en que se produce la invalidez y el porcentaje de la misma.

    Full Text Available FUNDAMENTO: Los accidentes por exposición percutánea suponen aproximadamente un tercio de los accidentes laborales del personal sanitario hospitalario. Su importancia estriba en las enfermedades causadas por patógenos transmisibles por esta vía (hepatitis B, hepatitis C, infección VIH. Objetivos: describir los accidentes de este tipo notificados en un hospital de tercer nivel; identificar factores asociados a estos accidentes en personal de enfermería; construir un modelo predictivo del riesgo individual de accidentarse. MÉTODOS: Estudio descriptivo de una cohorte retrospectiva compuesta por todas las personas que notificaron un accidente entre el 1-1-93 y el 30-6-96. Estudio de casos y controles en el personal de enfermería durante el período 1-1-95 al 30-6-96, analizado mediante regresión logística múltiple. RESULTADOS: La incidencia acumulada de accidentes en un año fue de 0,078 para las/-os enfermeras/-os. En el 57,3% de los casos estuvieron implicadas agujas de jeringas desechables o precargadas. La incidencia acumulada en un año fue mayor para las agujas de cateterismo intravenoso (8,5 por 100.000. El riesgo de accidentabilidad, ajustado por variables confundentes, fue mayor para las/-os enfermeras/-os (OR=3,22; I.C.95%=1,96-5,27, para los trabajadores de la Unidad de Hemodiálisis (OR=35,21; I.C.95%=3,74-331,16 y para aquéllos con contrato eventual (OR=4,50; I.C.95%=2,24-9,04. CONCLUSIONES: Los accidentes por exposición percutánea en este hospital son más frecuentes entre el personal de enfermería y se producen, fundamentalmente, con algún tipo de aguja hueca. Se han identificado factores asociados a estos accidentes, lo que permite dirigir programas preventivos específicos sobre trabajadores con más riesgo. El modelo obtenido es válido para estimar el grado de accidentabilidad individual en los sujetos estudiados.

    This paper provides some easy-to-use equations, which provide quick, realistic estimates of dispersion distances resulting from accidental airborne releases. Distance to toxic endpoint is the maximum dispersion distance for which resulting, airborne chemical concentrations would be in excess of specified exposure levels; broadly speaking accidental releases of toxic chemicals to the atmosphere can occur in urban or rural areas, either during the daytime or nigh time; this article focuses only on urban releases and uses Briggs sigma functions. Similar analysis can be developed for rural area and for different sigma functions e.g. Pasquill-Gifford sigmas and Juelich sigmas. (author)

    This article takes its cue from the original work of sir Alexander Fleming on penicillin, published in the first issue of Recenti Progressi in Medicina in 1946 and reproduced here on the occasion of the approaching 70-year anniversary of the journal. The path that brought Fleming to the discovery of penicillin, one of the major milestones in the history of clinical pharmacology, provides insight for a range of considerations: the painstaking efforts of researchers, the contribution from accidental findings, and the dissemination of study results. Although the discovery of penicillin has changed the course of medicine, the benefits deriving from such an important advance are most likely to be offset by the overprescription of antibiotics, which is the leading cause of antimicrobial resistance and one of the most serious public health problems of our time.

    This report describes a comparison of the MARC (Methodology for Assessing Radiological Consequences) and CRAC2 (Calculation of Reactor Accident Consequences, version 2) computer programs for assessing the radiological consequences of accidental releases of radioactive material. A qualitative comparison has been made of the features of the constituent sub-models of the two codes, and potentially the most important differences identified. The influence of these differences has been investigated quantitatively by comparison of the predictions of the two codes in a wide variety of circumstances. Both intermediate quantities and endpoints used as a measure of risk have been compared in order to separate the variables more clearly. The results indicate that, in general, the predictions of MARC and CRAC2 are in good agreement.

    Today, the widespread use of laser instruments in various fields has resulted in many accidental retinal injuries. Here we describe a rare clinical case of full-thickness macular hole (MH) and focal choroidal excavation (FCE) caused by a 1064-nm Q-switched Nd:YAG laser. After pars plana vitrectomy and the following 14 months, consecutive optical coherence tomography imagings showed closure of the MH. Visual acuity improved even in the absence of the outer retina and in the presence of FCE. We speculate that different focusing effects of the unexpected Nd:YAG lasers which target different levels of retinal tissue generate diverse prognosis. Copyright © 2017 Elsevier B.V.

    This longitudinal, observational study explored the relationship between physical performance tests, self-reported outcomes, and accidental falling, before and after total knee arthroplasty (TKA). Thirty-seven patients were randomly selected from a larger study of falling before and after surgery conducted at a UK National Health Service Orthopaedic Unit. Physical performance tests were the Berg Balance Score (BBS), Timed Up and Go (TUG), and Hand Grip Strength (HGS). Self-reported outcomes incorporated the Western Ontario and McMaster's Osteoarthritis Index (WOMAC), Activities Balance Confidence Scale (ABC-UK), Geriatric Depression Scale (GDS), and accidental falls. Paired pre- and postoperative data were available on 22 patients. A total of 22.7% patients fell before and after TKA. Postoperative improvement in BBS and TUG was found in 41% and 50% of patients, respectively, HGS did not change. BBS showed a consistent moderate-to-strong association with other physical tests both before and after surgery; TUG (rs -0.76; rs -0.90), maximal HGS (r 0.49; r 0.48), and self-report measures; ABC-UK (r 0.52; r 0.74), WOMAC stiffness (r -0.53; r -0.48), and WOMAC function (r -0.56; r -0.45). Although self-report questionnaires are an efficient, cost-effective approach to outcome assessment in TKA, there is a growing case for inclusion of physical performance tests. The Berg Balance Score may be a useful addition to outcome assessment in patients with TKA.

    Full Text Available Background: Injuries from occupational accidents are associated with agents of biological risk, as they are the gateway to serious and potentially lethal infectious diseases that can be spread by contact between people. Several studies have demonstrated that dental students are among the most vulnerable to blood borne exposure. Materials and Methods: To assess the knowledge, attitude and practice regarding risk of HIV transmission through accidental needle stick injury amongst dental students and providing supportive and proper guidelines regarding needle stick injuries and HIV infection. Study Design: This was a cross sectional study done at a dental college attached to a tertiary care hospital which included third, fourth year students and interns. The results obtained were subjected to statistical analysis using Chi square test. Results: Of the 120 students 13(11% were not even aware that virus could be transmitted through infected needle. A significant proportion of the third year students i.e. 27 (67.5% were not aware of correct method of disposal of disposable needles and syringes as against interns 17(42.5%. Around 31(26% said that they would promote active bleeding at the site of injury and 37(30% said they would take post exposure prophylaxis. Conclusion: Dental professionals are at a risk of occupational acquisition of HIV primarily due to accidental exposure to infected blood and body fluids. There is a need of correcting the existing misconceptions through education programmes early in the course and providing supportive and proper guidelines regarding needle stick injuries and HIV infection.

    Full Text Available Fundamentos: En los países desarrollados los accidentes infantiles ocupan los primeros lugares como causa de mortalidad. El objetivo de este trabajo es describir su evolución en España desde 1975 a 1994, así como su distribución por Comunidades Autónomas. Método: Con las defunciones por accidentes y las poblaciones de España y sus Comunidades Autónomas de 1 a 14 años de las estadísticas oficiales de mortalidad se han calculado los siguientes indicadores: porcentajes sobre el total de defunciones, tasas brutas de mortalidad, tasas ajustadas por edad, tasas específicas por grupos de edad y riesgos relativos. Estos indicadores han sido calculados por género, año de defunción y Comunidad Autónoma. Resultados: Entre 1975 y 1994 se ha reducido la mortalidad por accidentes infantiles en España, en un 3% anual en las niñas y en un 3,5% en los niños. La razón niños/niñas se ha mantenido alrededor de 2. Los accidentes de tráfico han supuesto en torno al 50%. Aragón presentaba el riego relativo más bajo tanto en niñas como en niños, con 0,54 y 0,57 respectivamente, y Galicia el más alto con 1,73 en niñas y 1,91 en niños. El porcentaje sobre el total de defunciones infantiles fue muy variable entre las Comunidades Autónomas, mientras que el porcentaje de accidentes de tráfico estuvo alrededor del 50% en todas las Comunidades Autónomas. Conclusiones: En España la mortalidad por accidentes infantiles ha descendido de una manera notable, en la actualidad se estima que los niños mueren un 50% menos que en 1975. La distribución por Comunidades Autónomas presenta grandes diferencias.

    Full Text Available São discutidos os aspectos relativos ao diagnóstico e tratamento dos hemangiomas cavernosos do crânio. Os dados obtidos em 26 casos, são apresentados, sendo salientado que a localização dos hemangiomas foi maior na região frontal, sendo mais atingido o sexo masculino. Os outros aspectos são coincidentes com os demais autores. A problemática desses tumores, principalmente a sua demonstração radiológica e o seu tratamento, são ressaltados, chegando-se à conclusão final de que o melhor meio de demonstração radiológica é a punção para contrastação direta do tumor. O tratamento de escolha é o cirúrgico, sendo a extirpação em bloco preferida nos casos de comprometimento ósseo importante, sendo a intervenção direta com dissecção e excisão reservada para as localizações nos tecidos moles ou com mínima participação óssea.

    Fire is a recurrent disturbance in savanna vegetation and savanna species are adapted to it. Even so, fire may affect various aspects of plant ecology, including phenology. We studied the effects of a spatially heterogeneous fire on the reproductive phenology of two dominant woody plant species, Miconia albicans (Melastomataceae) and Schefflera vinosa (Araliaceae), in a savanna area in South-eastern Brazil. The study site was partially burnt by a dry-season accidental fire in August 2006, and we monitored the phenolology of 30 burnt and 30 unburnt individuals of each species between September 2007 and September 2008. We used restricted randomizations to assess phenological differences between the burnt and unburnt individuals. Fire had negative effects on the phenology of M. albicans, with a smaller production of reproductive structures in general and of floral buds, total fruits, and ripe fruits in burnt plants. All unburnt but only 16% of the burnt M. albicans plants produced ripe fruits during the study. Fire effects on S. vinosa were smaller, but there was a greater production of floral buds and fruits (but not ripe fruits) by burnt plants; approximately 90% of the individuals of S. vinosa produced ripe fruits during the study, regardless of having been burnt or not. The differences between the two species may be related to S. vinosa's faster growth and absence from the seed bank at the study site, whereas M. albicans grows more slowly and is dominant in the seed bank.

    A next frontier of the global food safety agenda has to consider a broad spectrum of bio-risks, such as accidental and intentional contaminations in the food and feed chain. In this article, the background for the research needs related to biotraceability and response to bioterrorism incidents are outlined. Given the current scale of international trade any response need to be considered in an international context. Biotraceability (e.g. the ability to use downstream information to point to processes or within a particular food chain that can be identified as the source of undesirable agents) is crucial in any food-born outbreak and particular in the response to bioterrorism events. In the later case, tested and proven biotraceability improves the following: (i) international collaboration of validated tracing tools and detection methods, (ii) multi-disciplinary expertise and collaboration in the field of food microbiology and conceptual modeling of the food chain, (iii) sampling as a key step in biotracing (iv) optimized sample preparation procedures, including laboratory work in Biosafety level 3 (BSL-3) laboratories, (v) biomarker discovery for relevant tracing and tracking applications, and (vi) high-throughput sequencing using bio-informatic platforms to speed up the characterization of the biological agent. By applying biotraceability, the response phase during a bioterrorism event may be shortened and is facilitated for tracing the origin of biological agent contamination.

    1962-08-01

    On Saturday morning, April 7, 1962, at about 1059 Armed Forces time, an accidental nuclear excursion occurred in the plutonium waste recovery facility (Recuplex) of the 234-5 Building. This excursion did not result in any mechanical damage or spread of contamination. Three employees of the General Electric Company received overexposures to gamma and neutron radiation. None were fatally exposed; in each case the overexposure was recognized promptly, and following medical observation and testing the men were released to return to work. In compliance with AEC Manual Chapter 0703, an AEC-HAPO committee composed of two AEC employees and five General Electric employees was appointed by the Manger, HOO, with the concurrence of the General Manager, HAPO, to conduct an investigation of the incident. The committee`s purpose was to determine the cause, nature, and extent of the incident, and recommend action to be taken by others to minimize or preclude future incidents of this magnitude. A study of operating practices and operating conditions that appeared to exist prior to, during, and subsequent to the accident was made by the committee. The committee believes that this report provides sufficient information to answer questions which may arise as a result of the criticality incident except those relating to its cause.

    Watersports equipment can act as a vector for the introduction and spread of invasive non native species (INNS) in freshwater environments. To support advice given to recreational water users under the UK Government's Check Clean Dry biosecurity campaign and ensure its effectiveness at killing a range of aquatic INNS, we conducted a survival experiment on seven INNS which pose a high risk to UK freshwaters. The efficacy of exposure to hot water (45 °C, 15 min) was tested as a method by which waters users could 'clean' their equipment and was compared to drying and a control group (no treatment). Hot water had caused 99 % mortality across all species 1 h after treatment and was more effective than drying at all time points (1 h: χ2 = 117.24, p hot water or drying, 6/7 of these species survived for 16 days, highlighting the importance of good biosecurity practice to reduce the risk of accidental spread. In an additional experiment the minimum lethal temperature and exposure time in hot water to cause 100 % mortality in American signal crayfish (Pacifastacus leniusculus), was determined to be 5 min at 40 °C. Hot water provides a simple, rapid and effective method to clean equipment. We recommend that it is advocated in future biosecurity awareness campaigns.

    We investigate the influence of the regional-scale weather types on the atmospheric dispersion processes of the air pollutants originated from point sources. Hypothetical accidents were simulated with two different dispersion models. During a year's test period, the 6-h emission of a radionuclide from the Paks Nuclear Power Plant (Paks NPP, Hungary) was assumed every day and the transport and deposition of the radionuclide was simulated by the Eulerian TREX dispersion model over the Central European region. In addition, the ALOHA Gaussian air dispersion model was also used for the local environment of the Paks NPP to simulate hypothetical hourly releases of ammonia during a 10-year period. During both types of model simulations, the dispersion of the plume for each time was analysed and tested with consideration of 13 circulation types corresponding to daily weather patterns over the Carpathian Basin. There are significant correlations between circulation types and plume directions and structures both in local and regional scales. The daily circulation pattern can be easily obtained from weather analyses; the expected size and direction of polluted area after an accidental release can be quickly estimated even before an accident occurs. However, this fast method cannot replace or neglect dispersion model simulations. It gives a `first guess' and a fast estimation on the direction of the plume and can provide sufficient information for decision-making strategies.

    In the current industrial scenario there is a serious need for formulating strategies to handle hazardous substances in the safest way. Manufacture, storage, and use of hazardous substances pose a serious risk to industry, people, and the environment. Accidental release of toxic chemicals can lead to emergencies. An emergency response plan (ERP) is inevitable to minimize the adverse effects of such releases. The on-site emergency plan is an integral component of any process safety and risk management system. This paper deals with an on-site emergency response plan for a chlorine manufacturing industry. It was developed on the basis of a previous study on chlorine release and a full scale mock drill has been conducted for testing the plan. Results indicated that properly trained personnel can effectively handle each level of incidents occurring in the process plant. As an extensive guideline to the district level government authorities for off-site emergency planning, risk zone has also been estimated with reference to a chlorine exposure threshold of 3 ppm.

    Full Text Available Soil contamination represents an environmental issue which has become extremely important in the last decades due to the diffusion of industrial activities. Accidents during transport of dangerous materials and fuels may cause severe pollution. The present paper describes the criteria of the actions which were operated to remediate the potential risk and observed negative effects on groundwater and soil originating from an accidental spill of diesel fuel from a tank truck. With the aim to evaluate the quality of the involved environmental matrices in the “emergency” phase, in the following “safety” operation and during the remediation action, a specific survey on hydrocarbons, light and heavy, was carried out in the sand deposits soil. Elaboration of collected data allows us to observe the movement of pollutants in the unsaturated soil. The remediation action was finalized to improve the groundwater and soil quality. The former was treated by a so called “pump and treat” system coupled with air sparging. A train of three different technologies was applied to the unsaturated soil in a sequential process: soil vapour extraction, bioventing and enhanced bioremediation. Results showed that the application of sequential remediation treatments allowed us to obtain a state of quality in unsaturated soil and groundwater as required by Italian law.

    Many children who are victims of non-accidental trauma (NAT) may be repeatedly evaluated for injuries related to maltreatment. The purpose of this study was to identify risk factors for repeated injuries in children with suspected NAT. We conducted a retrospective cohort study using claims data from a pediatric Medicaid accountable care organization. Children with birth claims and at least one non-birth related claim indicating a diagnosis of NAT or skeletal survey in 2007-2011 were included. Recurrent events were defined as independent episodes of care involving an urgent/emergent care setting that included a diagnosis code specific for child abuse, a CPT code for a skeletal survey, or a diagnosis code for an injury suspicious for abuse. Cox proportional hazards models were used to examine risk factors for recurrent events. Of the 1,361 children with suspected NAT, a recurrent NAT event occurred in 26% within 1 year and 40% within 2 years of their initial event. Independent risk factors for a recurrent NAT event included a rural residence, age < 30 months old, having only 1 or 2 initially detected injuries, and having a dislocation, open wound, or superficial injury at the previous event (p ≤ 0.01 for all). Over 25% of children who experienced a suspected NAT event had a recurrent episode within one year. These children were younger and more likely to present with "minor" injuries at their previous event.

    Due to urgency of the accidental pollution events (APE) on one side and the variability in water quality data on the other side, a new online monitoring and management system (OMMS) was developed for the purpose of sustainable water quality management and human health protection as well. The Biological Early Warning System (BEWS) based on the behavioral responses (behavior strength) of medaka (Oryzias latipes) were built in combination with the physico-chemical factor monitoring system (PFMS) in OMMS. OMMS included a monitoring center and six monitoring stations. Communication between the center and the peripheral stations was conducted by the General Packet Radio Service (GPRS) network transmission complemented by a dial-up connection for use when GPRS was unavailable. OMMS could monitor water quality continuously for at least 30 days. Once APEs occurred, OMMS would promptly notify the administrator to make some follow up decisions based on the Emergency Treatment of APE. Meanwhile, complex behavioral data were analyzed by Self-Organizing Map to properly classify behavior response data before and after contamination. By utilizing BEWS, PFMS and the modern data transmission in combination, OMMS was efficient in monitoring the water quality more realistically.
