Two people out of three who accidentally ate boiled aconite leaves died in 2012. This was a typical case of aconite poisoning in Japan: Aconite (Aconitum spp.) was mistakenly collected instead of Anemone flaccida, an edible wild plant. The leaves of these plants are quite similar to each other. Chemical analyses of the aconite plant left at the scene suggested intake of a fatal amount of aconitine alkaloids by each person. The collector, who died, had missed the botanical differences between the two plants, even though he owned a wild plant guidebook. A. flaccida should be collected with its flowers in order to aid positive indentification and avoid aconite poisoning.

Food allergy is not always correctly diagnosed in children with atopic eczema dermatitis syndrome (AEDS) and treatment with an avoidance diet is not without danger. After admission to our clinic, 11 children with a prolonged cow's milk (CM) elimination diet because of AEDS and sensitization underwent double-blind placebo-controlled food challenge (DBPCFC). Retrospectively, the exposure to CM, sensitization and reactions to accidental ingestion were carefully documented. The DBPCFC was used to evaluate the childrens' current status. Before the elimination period (median 2.3 years; started before the admission) all 11 children with AEDS were sensitized and had ingested CM (four bottle-fed; seven breast-fed without CM diet of the mother) without the development of acute reactions. The diagnosis of CM allergy was not confirmed by DBPCFC previously. After elimination the AEDS had not improved, but nevertheless the diet was continued. During the elimination period, eight of 11 children developed severe acute allergic reactions to CM after accidental ingestion. In evaluation, in our clinic all 11 children experienced acute allergic reactions to CM during DBPCFC. There is a considerable chance of developing acute allergic reactions to CM after elimination in children with AEDS without previous problems after CM intake.

Lithium is an effective drug in the treatment of bipolar disorder and other psychiatric and neurological diseases. Unfortunately, its therapeutic index is narrow. There are three types of lithium poisoning: acute poisoning (in untreated patients), acute on chronic poisoning, when an overdose is taken accidentally or with suicidal intent, in patients under treatment and chronic poisoning (patient treated with lithium) when drug intake is correct but excessive in relation to its elimination (increased dose or more often reduced clearance) resulting in lithium overload. In this last condition, the clinical presentation is primary neurological while therapy involves the nephrologist provided that lithium clearance is mainly renal and hemodialysis is the most effective method for removal.

Caffeine is an adenosine receptor antagonist and a possible cause of inadequate stress perfusion. Splenic switch-off (SSO) and splenic rest-stress T1-mapping have been proposed as indicators of stress adequacy during perfusion cardiac magnetic resonance (CMR). We compared myocardial rest-stress T1-mapping with SSO and splenic rest-stress T1-mapping in patients with and without recent coffee intake. We analyzed 344 consecutive patients suspected of myocardial ischemia with adenosine perfusion CMR. All 146 normal CMR studies with a normal T1-rest of the myocardium, used as standard of reference, were included and divided in two groups. 22 patients accidentally ingested coffee < 4 h before CMR, compared to control group of 124 patients without self-reported coffee intake. Two independent readers graded SSO visually. T1-reactivity (ΔT1) was defined as percentual difference in T1-rest and T1-stress. Follow-up data were extracted from electronic patients records. In patients with recent coffee intake SSO was identified in 96%, which showed no significant difference with SSO in controls (94%, p = 0.835), however event rates were significantly different (13.6 and 0.8%, respectively (p < 0.001), median FU 17 months). Myocardial ΔT1 in the coffee group (- 5.2%) was significantly lower compared to control (+ 4.0%, p < 0.001), in contrast to the splenic ΔT1 (- 3.7 and - 4.0%, p = 0.789). The splenic T1-mapping results failed to predict false negative results. SSO and splenic rest-stress T1-mapping are not reliable indicators of stress adequacy in patients with recent coffee intake. Therefore, the dark spleen sign does not indicate adequate myocardial stress in patients with recent caffeine intake. Myocardial rest-stress T1-mapping is an excellent indicator of stress adequacy during adenosine perfusion CMR.

Several educational intervention programs have been designed and developed to improve osteoporosis diagnosis and treatment. However, most of the prior studies focused on how educational intervention programs affected diagnosis and treatment of condition of osteoporosis. The purpose of this prospective and educational intervention study was to evaluate the changes in osteoporosis knowledge, osteoporosis self-efficacy, fall self-efficacy, physical exercise and changes in dietary pattern of calcium and vitamin D intake after osteoporosis education. From November 1, 2015 to August 31, 2016, 271 eligible candidates (who were over 50 years old and from 23 different community centers) were recruited through an announcement made by the public office, by two health care providers. The intervention involved an individualized education program to allow for differences in antecedent educational levels regarding several aspects of osteoporosis, including osteoporosis knowledge, osteoporosis self-efficacy, awareness of self-efficacy risk factors relating to an accidental fall and nutritional education (including the importance of sufficient calcium and vitamin D intake). The researchers revisited the community centers three months after the initial visit. Of the 271 potential participants, 199 (73.4%; 43 men and 156 women) completed the education program and the second questionnaire. After education intervention, parameters including osteoporosis knowledge, osteoporosis self-efficacy and fall self-efficacy were improved (P < 0.0001). After education regarding percentage of calcium and vitamin D intake below recommended cut-offs, inadequate dietary calcium and vitamin D intake were decreased (P < 0.0001) from 89.4% (178/199) and 84.4% (168/199) to 79.9% (159/199) and 65.8% (131/199), respectively, at the three-month follow-up. (p = 0.038, p = 0.017). This prospective intervention study demonstrated that education on osteoporosis knowledge and regular exercise programs could improve osteoporosis self- efficacy, fall self-efficacy and increase dietary calcium and vitamin D intake.

White or false hellebore (Veratrum album) has a toxicological relevance because of the potential for misidentification of this plant as yellow gentian (Gentiana lutea). We report a retrospective case series of 11 children (8-12 years) with accidental intake of V. album at a youth camp where they had collected herbs for preparing fresh herb tea. Two children (18%) remained asymptomatic. Nine (82%) developed mild gastrointestinal symptoms, six (55%) presented neurological symptoms, and three (27%) showed bradycardia. All children recovered completely within 10 h of ingestion. The plant was identified at the emergency department; however, detection of veratridine and cevadine by means of high-performance liquid chromatography-Mass spectrometry from the blood of the child with the most severe symptoms was negative (limit 0.01 ng/mL). Veratrum species contain more than 200 different alkaloids, which are the principal toxins and are responsible for most clinical symptoms. There are likely multiple mechanisms of toxicity and some of them are only partially understood. The opening of voltage-gated sodium channels is probably one of the most relevant pathophysiological mechanisms. Veratrum album intoxication in children demonstrated the same clinical course as observed in adults. Accidental ingestion of a low dose of the plant had a favorable outcome with supportive care.

Selective serotonin reuptake inhibitors (SSRIs) are widely used to treat depression and are also associated with an increased falls risk. However, the biological mechanism underlying accidental falls with SSRI intake has yet to be elucidated. The present experimental study was designed to investigate whether obstacle avoidance skills in long-term (>90 days), senior paroxetine users (61 ± 5.8 years) are affected during gait, simple and challenging postural balance tasks, as well as during manual reaction time tasks. The performance of the paroxetine users was compared with healthy group-matched controls (60 ± 4.8 years). The results demonstrated impaired postural balance in the paroxetine users, especially during one-legged stance or under various dual-task conditions. Although the deficit in one-legged stance could indicate vestibular involvement, this was deemed unlikely because performance of standing on compliant surface with closed eyes remained unaffected. Paroxetine use also failed to affect manual reaction times or obstacle avoidance performance. It is suggested that paroxetine affects attentional capacities particularly in conjunction with balance control. Compared with healthy seniors, long-term senior users of paroxetine seem to be at an increased risk of falling due to impairments in balance control, especially when attention has to be divided between 2 concurrent activities.

Social evaluation of intentional, truly accidental, and negligently accidental helpers and harmers by 10-month-old infants.

Whereas adults largely base their evaluations of others' actions on others' intentions, a host of research in developmental psychology suggests that younger children privilege outcome over intention, leading them to condemn accidental harm. To date, this question has been examined only with children capable of language production. In the current studies, we utilized a non-linguistic puppet show paradigm to examine the evaluation of intentional and accidental acts of helping or harming in 10-month-old infants. In Experiment 1 (n=64), infants preferred intentional over accidental helpers but accidental over intentional harmers, suggestive that by this age infants incorporate information about others' intentions into their social evaluations. In Experiment 2 (n=64), infants did not distinguish "negligently" accidental from intentional helpers or harmers, suggestive that infants may find negligent accidents somewhat intentional. In Experiment 3 (n=64), we found that infants preferred truly accidental over negligently accidental harmers, but did not reliably distinguish negligently accidental from truly accidental helpers, consistent with past work with adults and children suggestive that humans are particularly sensitive to negligently accidental harm. Together, these results imply that infants engage in intention-based social evaluation of those who help and harm accidentally, so long as those accidents do not stem from negligence.

Experience with intubated patients does not affect the accidental extubation rate in pediatric intensive care units and intensive care nurseries.

PubMed

Frank, B S; Lewis, R J

1997-06-01

Accidental extubation is a potentially serious event for pediatric or neonatal patients with respiratory failure, especially in clinical settings in which personnel capable of performing reintubation may not be readily available. Thus the rate of accidental extubation in small intensive care units that operate without 24-hour in-house physician availability may be an important quality assurance indicator. The objective of this study were to determine the accidental extubation rate at a single small pediatric intensive care unit (PICU) and compare it with published reports. This study was carried out in a six-bed PICU at Washoe Medical Center in Reno, Nevada, with a relatively low level of patient acuity, as measured by PRISM score and the frequency of intubation, and without 24-hour in-house physician availability. All intubated patients admitted during the 5-year period from January 1, 1989 to December 31, 1993 were included. The primary outcome measure was the occurrence of accidental extubation. We observed only two accidental extubations in 1,749 intubated-patient-days (IPD) (0.114 accidental extubations/100 IPD [95% confidence interval 0.014-0.413 accidental extubations/ 100 IPD]). This rate of accidental extubation was compared with data in published reports from neonatal intensive care units (NICUs) and PICUs, which ranged from 0.14 accidental extubations/100 IPD to 4.36 accidental extubations/100 IPD. The dependence of the observed accidental extubation rate on unit size and institutional experience with intubated patients, as measured by the average number of intubated patients, was examined. We found no evidence that the accidental extubation rate is higher in smaller units or units with less institutional experience. Low rates can be achieved in small units with low acuity.

[Sports and extreme conditions. Cardiovascular incidence in long term exertion and extreme temperatures (heat, cold)].

PubMed

Melin, B; Savourey, G

During ultra-endurance exercise, both increase in body temperature and dehydration due to sweat losses, lead to a decrease in central blood volume. The heart rate drift allows maintaining appropriate cardiac output, in order to satisfy both muscle perfusion and heat transfer requirements by increasing skin blood flow. The resulting dehydration can impair thermal regulation and increase the risks of serious accidents as heat stroke. Endurance events, lasting more than 8 hours, result in large sweat sodium chloride losses. Thus, ingestion of large amounts of water with poor salt intake can induce symptomatic hyponatremia (plasma sodium < 130 mEq/L) which is also a serious accident. Heat environment increases the thermal constraint and when the air humidity is high, evaporation of sweat is compromise. Thus, thermal stress becomes uncompensable which increases the risk of cardiovascular collapse. Cold exposure induces physiological responses to maintain internal temperature by both limiting thermal losses and increasing metabolic heat production. Cold can induce accidental hypothermia and local frost-bites; moreover, it increases the risk of arrhythmia during exercise. Some guidelines (cardiovascular fitness, water and electrolyte intakes, protective clothing) are given for each extreme condition.

Time-of-travel and dispersion studies, Lehigh River, Francis E. Walter Lake to Easton, Pennsylvania

Results of time-of-travel and dispersion studies are presented for the 77.0 mile reach of the Lehigh River from Francis E. Walter Lake to Easton, Pennsylvania. Rhodamine WT dye was injected at several points for a variety of several common flow conditions and its downstream travel was monitored at a number of downstream points by means of a fluorometer. Time-of-travel data have been related to stream discharge, distance along the river channel and dispersion. If 2.205 pounds of a conservative water soluble contaminant were accidentally spilled into the Lehigh River at Penn Haven Junction at Black Creek 6.09 miles downstream from Rockport, Pennsylvania, when the discharge at Walnutport, Pennsylvania, was 600 cubic feet per second, the leading edge, peak, and trailing edge of the contaminant would arrive 31.6 miles downstream at the Northhampton, Pennsylvania, water intakes 45, 54, and 66 hours later, respectively. The maximum concentration expected at the intakes would be about 1.450 micrograms per liter. From data and relations presented, time-of-travel and maximum concentration estimates can be made for any two points within the reach. (USGS)

The case of a 6 year old child who presented with convulsions and coma after unsupervised self administration of intranasal desmopressin (DDAVP) for nocturnal enuresis is presented. Children with enuresis can be embarassed by their condition and may believe that multiple doses of their nasal spray may bring about a rapid resolution. Water intoxication is an uncommon but serious adverse effect of treatment with intranasal DDAVP. These patients may present with seizure, mental state changes, or both. Basic management consists of stopping the drug, fluid restriction, and suppressive treatment for seizures. Recovery is usually rapid and complete. Administration of the nasal spray in children should be supervised by parents to prevent highly motivated children from accidental overdose. The risks of high fluid intake need to be carefully explained to both parents and children.

Accidental introductions are an important source of invasive plants in the continental United States.

2013-07-01

Preventing new plant invasions is critical for reducing large-scale ecological change. Most studies have focused on the deliberate introduction of nonnatives via the ornamental plant trade. However, accidental introduction may be an important source of nonnative, invasive plants. Using Web and literature searches, we compiled pathways of introduction to the United States for 1112 nonnative plants identified as invasive in the continental United States. We assessed how the proportion of accidentally and deliberately introduced invasive plants varies over time and space and by growth habit across the lower 48 states. Deliberate introductions of ornamentals are the primary source of invasive plants in the United States, but accidental introductions through seed contaminants are an important secondary source. Invasive forbs and grasses are the most likely to have arrived accidentally through seed contaminants, while almost all nonnative, invasive trees were introduced deliberately. Nonnative plants invading eastern states primarily arrived deliberately as ornamentals, while a high proportion of invasive plants in western states arrived accidentally as seed contaminants. Accidental introductions may be increasing in importance through time. Before 1850, 10 of 89 (11%) of invasive plants arrived accidentally. After 1900, 20 of 65 (31%) arrived accidentally. Recently enacted screening protocols and weed risk assessments aim to reduce the number of potentially invasive species arriving to the United States via deliberate introduction pathways. Increasing proportions of accidentally introduced invasive plants, particularly associated with contaminated seed imports across the western states, suggest that accidental introduction pathways also need to be considered in future regulatory decisions.

Metabolism and physiologically based pharmacokinetic modeling of flumioxazin in pregnant animals

A physiologically based pharmacokinetic (PBPK) model was developed to predict the concentration of flumioxazin, in the blood and fetus of pregnant humans during a theoretical accidental intake (1000 mg/kg). The data on flumioxazin concentration in pregnant rats (30 mg/kg po) was used to develop the PBPK model in pregnant rats using physiological parameters and chemical specific parameters. The rat PBPK model developed was extrapolated to a human model. Liver microsomes of female rats and a mixed gender of humans were used for the in vitro metabolism study. To determine the % of flumioxazin absorbed after administration at a dose ofmore » 1000 mg/kg assuming maximum accidental intake, the biliary excretion study of [phenyl-U-{sup 14}C]flumioxazin was conducted in bile duct-cannulated female rats (Crl:CD (SD)) to collect and analyze the bile, urine, feces, gastrointestinal tract, and residual carcass. The % of flumioxazin absorbed at a dose of 1000 mg/kg in rats was low (12.3%) by summing up {sup 14}C of the urine, bile, and residual carcass. The pregnant human model that was developed demonstrated that the maximum flumioxazin concentration in the blood and fetus of a pregnant human at a dose of 1000 mg/kg po was 0.86 μg/mL and 0.68 μg/mL, respectively, which is much lower than K{sub m} (202.4 μg/mL). Because the metabolism was not saturated and the absorption rate was low at a dose of 1000 mg/kg, the calculated flumioxazin concentration in pregnant humans was thought to be relatively low, considering the flumioxazin concentration in pregnant rats at a dose of 30 mg/kg. For the safety assessment of flumioxazin, these results would be useful for further in vitro toxicology experiments. - Highlights: • A PBPK model of flumioxazin in pregnant humans was developed. • Simulated flumioxazin concentration in pregnant humans was relatively low. • The results would be useful for further in vitro toxicology experiments.« less

Hazards of Improper Dispensary: Literature Review and Report of an Accidental Chloroform Injection.

PubMed

Verma, Prashant; Tordik, Patricia; Nosrat, Ali

2018-06-01

Several clear, transparent solutions are used in endodontics. Inappropriate dispensing methods can lead to accidental injection or accidental irrigation. These accidents can cause permanent tissue damage including damage to the bone, periodontium, nerves, and vasculature. This article reports on the consequences of an accidental chloroform injection. Nonsurgical retreatment of tooth #8 was planned as part of a restorative treatment plan in a 69-year-old woman. The dentist accidentally injected chloroform instead of local anesthesia because chloroform was loaded into the anesthetic syringe. The patient experienced severe pain and swelling and soft tissue necrosis and suffered permanent sensory and motor nerve damage. A review of the literature was performed on accidents caused by improper dispensary, namely accidental injections and accidental irrigations. The data were extracted and summarized. Sodium hypochlorite, chlorhexidine, formalin, formocresol, 1:1000 adrenaline, benzalkonium chloride, and lighter fuel were accidentally injected as an intraoral nerve block or as infiltration injections. Bone and soft tissue necrosis, tooth loss, and sensory nerve damage (anesthesia and paresthesia) were the most common consequences reported. Such disastrous events can be prevented by appropriate labeling and separate dispensing methods for each solution. There is a need for disseminating information on toxicity and biocompatibility of materials/solutions used in endodontics. The authors recommend training dental students and endodontic residents on immediate and long-term therapeutic management of patients when an accidental injection or accidental irrigation occurs.

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.

A framework for modeling contaminant impacts on reservoir water quality

2016-06-01

This study presents a framework for using hydrodynamic and water quality models to understand the fate and transport of potential contaminants in a reservoir and to develop appropriate emergency response and remedial actions. In the event of an emergency situation, prior detailed modeling efforts and scenario evaluations allow for an understanding of contaminant plume behavior, including maximum concentrations that could occur at the drinking water intake and contaminant travel time to the intake. A case study assessment of the Wachusett Reservoir, a major drinking water supply for metropolitan Boston, MA, provides an example of an application of the framework and how hydrodynamic and water quality models can be used to quantitatively and scientifically guide management in response to varieties of contaminant scenarios. The model CE-QUAL-W2 was used to investigate the water quality impacts of several hypothetical contaminant scenarios, including hypothetical fecal coliform input from a sewage overflow as well as an accidental railway spill of ammonium nitrate. Scenarios investigated the impacts of decay rates, season, and inter-reservoir transfers on contaminant arrival times and concentrations at the drinking water intake. The modeling study highlights the importance of a rapid operational response by managers to contain a contaminant spill in order to minimize the mass of contaminant that enters the water column, based on modeled reservoir hydrodynamics. The development and use of hydrodynamic and water quality models for surface drinking water sources subject to the potential for contaminant entry can provide valuable guidance for making decisions about emergency response and remediation actions.

Geology and hydrology of the Elk River, Minnesota, nuclear-reactor site

USGS Publications Warehouse

Norvitch, Ralph F.; Schneider, Robert; Godfrey, Richard G.

1963-01-01

The Elk River, Minn., nuclear-reactor site is on the east bluff of the Mississippi River about 35 miles northwest of Minneapolis and St. Paul. The area is underlain by about 70 to 180 feet of glacial drift, including at the top as much as 120 feet of outwash deposits (valley train) of the glacial Mississippi River. The underlying Cambrian bedrock consists of marine sedimentary formations including artesian sandstone aquifers. A hypothetically spilled liquid at the reactor site could follow one or both of two courses, thus: (1) It could flow over the land surface and through an artificial drainage system to the river in a matter of minutes; (2) part or nearly all of it could seep downward to the water table and then move laterally to the river. The time required might range from a few weeks to a year, or perhaps more. The St. Paul and Minneapolis water-supply intakes, 21 and 25 miles downstream, respectively, are the most critical points to be considered in the event of an accidental spill. Based on streamflow and velocity data for the Mississippi River near Anoka, the time required for the maximum concentration of a contaminant to travel from the reactor site to the St. Paul intake was computed to be about 8 hours, at the median annual maximum daily discharge. For this discharge, the maximum concentration at the intake would be about 0.0026 microcurie per cubic foot for the release of 1 curie of activity into the river near the reactor site.

The purpose of this study was to investigate the incidence, type, location, and risk factors of accidental fetal lacerations during cesarean delivery. Total deliveries, cesarean deliveries, and neonatal records for documented accidental fetal lacerations were reviewed retrospectively in our level III university hospital. The gestational age, the presenting part of the fetus, the cesarean delivery indication, the type of incision, and the surgeon who performed the procedure were recorded. Cesarean deliveries were divided into scheduled, unscheduled, and emergency procedures. Fetal lacerations were divided into mild, moderate, and severe. Neonatal follow-up examinations regarding laceration sequelae were available for 6 months. Of 14926 deliveries, 3108 women were delivered by cesarean birth (20.82%). Neonatal records documented 97 accidental fetal lacerations. Of these accidental lacerations, 94 were mild; 2 were moderate, and 1 was severe. The overall rate of accidental fetal laceration per cesarean delivery was 3.12%; the accidental laceration rate in the cohort of fetuses was 2.46%. The crude odds ratios were 0.34 for scheduled procedures, 0.57 for unscheduled procedures, and 1.7 for emergency procedures. The risk for fetal accidental lacerations was higher in fetuses who underwent emergency cesarean birth and lower for unscheduled and scheduled cesarean births (P < .001). Fetal accidental laceration may occur during cesarean delivery; the incidence is significantly higher during emergency cesarean delivery compared with elective procedures. The patient should be counseled about the occurrence of fetal laceration during cesarean delivery to avoid litigation.

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.

Risk assessment for stonecutting enterprises Accidental risks in the course of petroleum production and stone extraction

NASA Astrophysics Data System (ADS)

Aleksandrova, A. J.; Timofeeva, S. S.

2018-01-01

The paper is devoted to the assessment of accidental risks occurring at the works engaged in stone extracting and petroleum production. Two basic kinds of accidents common for stone extracting and petroleum production have been chosen to be discussed in the part under consideration. The most dangerous accidental situation characteristic for a stone milling line is an unsanctioned explosion, UE, of blasting agents used for the development of stone deposits. The analysis of a risk occurrence in certain accidental situations is to be carried out. With reference to petroleum extraction, a combustibles and lubricants (C & L) explosion is the most dangerous of characteristic accidental situations. To reveal the most probable causes of accidental situations to be realized, a graph of cause and effect relations has been constructed for each of the accidental situations most probable causes to real situation of an accident. Disasters of a natural origin are the most probable causes of unsanctioned explosions at the deposits of stone raw materials. Technology related natural disasters are the most probable causes of unsanctioned explosions to be realized at multiple well platforms engaged in petroleum production.

Accidental explosions are discussed from a number of viewpoints. First, all accidental explosions, intentional explosions and natural explosions are characterized by type. Second, the nature of the blast wave produced by an ideal (point source or HE) explosion is discussed to form a basis for describing how other explosion processes yield deviations from ideal blast wave behavior. The current status blast damage mechanism evaluation is also discussed. Third, the current status of our understanding of each different category of accidental explosions is discussed in some detail.

2011-11-01

Patients frequent take acetaminophen to treat dental pain. One previous study found a high rate of overuse of nonprescription analgesics in an emergency dental clinic. The purpose of this study is to determine if patients with dental pain are more likely to be treated for accidental acetaminophen poisoning than patients with other types of pain. We conducted a case-control study at 2 urban hospitals. Cases were identified by chart review of patients who required treatment for accidental acetaminophen poisoning. Controls were self-reported acetaminophen users taking therapeutic doses identified during a survey of emergency department patients. For our primary analysis, the reason for taking acetaminophen was categorized as dental pain or not dental pain. Our primary outcome was the odds ratio of accidental overdose to therapeutic users after adjustment for age, sex, alcoholism, and use of combination products using logistic regression. We identified 73 cases of accidental acetaminophen poisoning and 201 therapeutic users. Fourteen accidental overdose patients and 4 therapeutic users reported using acetaminophen for dental pain. The adjusted odds ratio for accidental overdose due to dental pain compared with other reasons for use was 12.8 (95% confidence interval, 4.2-47.6). We found that patients with dental pain are at increased risk to accidentally overdose on acetaminophen compared with patients taking acetaminophen for other reasons. Emergency physicians should carefully question patients with dental pain about overuse of analgesics. Copyright © 2011 Elsevier Inc. All rights reserved.

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 not risk factors for accidental awareness: ASA physical status; race; and use or omission of nitrous oxide. We recommend that an anaesthetic checklist, to be an integral part of the World Health Organization Safer Surgery checklist, is introduced as an aid to preventing accidental awareness.

Much of the information on the health effects of radiation exposure available to date comes from long-term studies of the atomic bombings in Hiroshima and Nagasaki. Accidental exposures, such as those resulting from the Chernobyl and Kyshtym accidents, have as yet provided little information concerning health effects of ionizing radiation. This paper will present the current state of our knowledge concerning radiation effects, review major large-scale accidental radiation exposures, and discuss information that could be obtained from studies of accidental exposures and the types of studies that are needed.

We present the main findings of the 5th National Audit Project (NAP5) on accidental awareness during general anaesthesia (AAGA). 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% confidence interval 1:16,700-23,450). However, there was considerable variation across subtypes of techniques or subspecialities. The incidence with neuromuscular block (NMB) was ~1:8200 (1:7030-9700), and without, it was ~1:135,900 (1:78,600-299,000). The cases of AAGA reported to NAP5 were overwhelmingly cases of unintended awareness during NMB. 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, NMB, and interruptions of anaesthetic delivery during movement from anaesthetic room to theatre.

Green-McKenzie, Judith; Shofer, Frances S

2007-01-01

Shift work has been found to be associated with an increased rate of errors and accidents among healthcare workers (HCWs), but the effect of shift work on accidental blood and body fluid exposure sustained by HCWs has not been well characterized. To determine the duration of time on shift before accidental blood and body fluid exposure in housestaff, nurses, and technicians and the proportion of housestaff who sustain a blood and body fluid exposure after 12 hours on duty. This retrospective, descriptive study was conducted during a 24-month period at a large urban teaching hospital. Participants were HCWs who sustained an accidental blood and body fluid exposure. Housestaff were on duty significantly longer than both nursing staff (P=.02) and technicians (P<.0001) before accidental blood and body fluid exposure. Half of the blood and body fluid exposures sustained by housestaff occurred after being on duty 8 hours or more, and 24% were sustained after being on duty 12 hours or more. Of all HCWs, 3% reported an accidental blood and body fluid exposure, with specific rates of 7.9% among nurses, 9.4% among housestaff, and 3% among phlebotomists. Housestaff were significantly more likely to have longer duration of time on shift before blood and body fluid exposure than were the other groups. Almost one-quarter of accidental blood and body fluid exposures to housestaff were incurred after they had been on duty for 12 hours or more. Housestaff sustained a higher rate of accidental blood and body fluid exposures than did nursing staff and technicians.

A prospective cohort study of non-fatal accidental overdose among street youth: the link with suicidal ideation.

Drug overdose and suicide are the two leading causes of death among street youth. The literature discusses the two faces of drug overdose: accidental act and suicide attempt. Some authors have stated that accidental overdoses may be a hidden expression of suicidal ideation. This study longitudinally examined the relationship between recent suicidal ideations and non-fatal accidental drug overdoses among street youth. Between July 2001 and December 2005, 858 street youth (14-23 years old) were recruited for a prospective cohort study. Youth were eligible if, in the previous year, they had been without a place to sleep more than once or had used the services of street youth agencies on a regular basis (≥3). Participants completed baseline questionnaires and follow-up interviews were carried out every 6 months. Mixed-effect logistic regression models were conducted. Apart from suicidal ideation and accidental drug overdose, variables considered in the model were age, sex, problematic alcohol use, homelessness, injection drug use and polydrug use (≥3 drugs). Accidental drug overdose was significantly associated with suicidal ideation (adjusted odds ratio 1.88; 95% confidence interval 1.23-2.54). Homelessness, injection drug use and polydrug use were also significant in the final model. Results show that, during follow up, suicidal ideation independently increased risks of accidental overdose. They also underscore the need for interventions beyond educational prevention. Primary care practitioners should investigate suicidal ideations and behaviours of street youth in treatment for accidental overdose. © 2012 Australasian Professional Society on Alcohol and other Drugs.

Accidental falls are a major public health concern among people of all ages. Little is known about whether an individual-level housing-based socioeconomic status measure is associated with the risk of accidental falls. Among 12,286 Mayo Clinic Biobank participants residing in Olmsted County, Minnesota, subjects who experienced accidental falls between the biobank enrollment and September 2014 were identified using ICD-9 codes evaluated at emergency departments. HOUSES (HOUsing-based Index of SocioEconomic Status), a socioeconomic status measure based on individual housing features, was also calculated. Cox regression models were utilized to assess the association of the HOUSES (in quartiles) with accidental fall risk. Seven hundred eleven (5.8%) participants had at least one emergency room visit due to an accidental fall during the study period. Subjects with higher HOUSES were less likely to experience falls in a dose-response manner (hazard ratio: 0.58; 95% confidence interval: 0.44-0.76 for comparing the highest to the lowest quartile). In addition, the HOUSES was positively associated with better health behaviors, social support, and functional status. The HOUSES is inversely associated with accidental fall risk requiring emergency care in a dose-response manner. The HOUSES may capture falls-related risk factors through housing features and socioeconomic status-related psychosocial factors. Copyright © 2017 Elsevier Inc. All rights reserved.

Our goal was to examine the effect of the World Trade Center (WTC) attack and subsequent New York City Fire Department (FDNY) rescue/recovery activities on firefighter retirements. We also analyzed the financial impact associated with the increased number and proportion of service-connected "accidental" disability retirements on the FDNY pension system. A total of 7,763 firefighters retired between 9/11/1994 and 9/10/2008. We compared the total number of retirements and the number and proportion of accidental disability retirements 7 years before and 7 years after the WTC attack. We categorized WTC-related accidental disability retirements by medical cause and worked with the New York City Office of the Actuary to approximate the financial impact by cause. In the 7 years before 9/11 there were 3,261 retirements, 48% (1,571) of which were accidental disability retirements. In the 7 years after 9/11, there were 4,502 retirements, 66% (2,970) were accidental disability retirements, of which 47% (1,402) were associated with WTC-related injuries or illnesses. After 9/11, the increase in accidental disability retirements was, for the most part, due to respiratory-related illnesses. Additional increases were attributed to psychological-related illnesses and musculoskeletal injuries incurred at the WTC site. Pension benefits associated with WTC-related accidental disability retirements have produced an increased financial burden of over $826 million on the FDNY pension system. The WTC attacks affected the health of the FDNY workforce resulting in more post-9/11 retirements than expected, and a larger proportion of these retirees with accidental disability pensions.

Accidental awareness during general anaesthesia - a narrative review.

PubMed

Tasbihgou, S R; Vogels, M F; Absalom, A R

2018-01-01

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 of Anaesthetists of Great Britain and Ireland.

Recent high-profile cases have made paediatricians very aware of the serious implications of either missing or wrongly diagnosing non-accidental injury. Subdural fluid collections in non-mobile infants usually represent haemorrhage caused by non-accidental injury. We report a 6-month-old male who presented to the Accident and Emergency Department of Birmingham Heartlands Hospital with bilateral subdural fluid collections and skin ulcers resembling cigarette burns. Non-accidental injury was considered to be the most likely diagnosis. However, while under observation in hospital, the child's neurological condition deteriorated with progressive cerebral infarctions, and serial photographs of the skin lesions showed failure to heal. The revised diagnosis, confirmed histologically, was Degos disease, an extremely rare and often fatal occlusive vasculopathy. The child was treated palliatively and died 8 weeks after presentation. This report informs doctors of a new simulator of non-accidental injury to be considered in infants with otherwise unexplained subdural fluid collections.

Accidental hanging by a T-shirt collar in a man with morphine intoxication: an unusual case.

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 hypothermia seems to predispose multiple trauma patients to the development of posttraumatic complications, such as Systemic Inflammatory Response Syndrome (SIRS), sepsis, Multiple Organ Dysfunction Syndrome (MODS), and increased mortality. However, the role of accidental hypothermia as an independent prognostic factor is controversially discussed. The aim of the present study was to evaluate the incidence of accidental hypothermia in multiple trauma patients and its effects on the development of posttraumatic complications and mortality. Inclusion criteria for patients in this retrospective study (2005-2009) were an Injury Severity Score (ISS) ≥16, age ≥16 years, admission to our Level I trauma centre within 6h after the accident. Accidental hypothermia was defined as body temperature less than 35°C measured within 2 h after admission, but always before first surgical procedure in the operation theatre. The association between accidental hypothermia and the development of posttraumatic complications as well as mortality was investigated. Statistical analysis was performed with χ(2)-test, Student's t-test, ANOVA and logistic regression. Statistical significance was considered at p<0.05. 310 multiple trauma patients were enrolled in the present study. Patients' mean age was 41.9 (SD 17.5) years, the mean injury severity score was 29.7 (SD 10.2). The overall incidence of accidental hypothermia was 36.8%. The overall incidence of posttraumatic complications was 77.4% (SIRS), 42.9% (sepsis) and 7.4% (MODS), respectively. No association was shown between accidental hypothermia and the development of posttraumatic complications. Overall, 8.7% died during the posttraumatic course. Despite an increased mortality rate in hypothermic patients, hypothermia failed to be an independent risk factor for mortality in multivariate analysis. Accidental hypothermia is very common in multiply injured patients. However, it could be assumed that the increase of mortality in hypothermic patients is primarily caused by the injury severity and does not reflect an independent adverse effect of hypothermia. Furthermore, hypothermia was not shown to be an independent risk factor for posttraumatic complications. Copyright © 2011 Elsevier Ltd. All rights reserved.

The impact of dust storms on human health has been studied in the context of Asian, Saharan, Arabian, and Australian storms, but there has been no recent population-level epidemiological research on the dust storms in North America. The relevance of dust storms to public health is likely to increase as extreme weather events are predicted to become more frequent with anticipated changes in climate through the 21st century. We examined the association between dust storms and county-level non-accidental mortality in the United States from 1993 through 2005. Dust storm incidence data, including date and approximate location, are taken from the U.S. National Weather Service storm database. County-level mortality data for the years 1993-2005 were acquired from the National Center for Health Statistics. Distributed lag conditional logistic regression models under a time-stratified case-crossover design were used to study the relationship between dust storms and daily mortality counts over the whole United States and in Arizona and California specifically. End points included total non-accidental mortality and three mortality subgroups (cardiovascular, respiratory, and other non-accidental). We estimated that for the United States as a whole, total non-accidental mortality increased by 7.4% (95% CI: 1.6, 13.5; p = 0.011) and 6.7% (95% CI: 1.1, 12.6; p = 0.018) at 2- and 3-day lags, respectively, and by an average of 2.7% (95% CI: 0.4, 5.1; p = 0.023) over lags 0-5 compared with referent days. Significant associations with non-accidental mortality were estimated for California (lag 2 and 0-5 day) and Arizona (lag 3), for cardiovascular mortality in the United States (lag 2) and Arizona (lag 3), and for other non-accidental mortality in California (lags 1-3 and 0-5). Dust storms are associated with increases in lagged non-accidental and cardiovascular mortality. Citation: Crooks JL, Cascio WE, Percy MS, Reyes J, Neas LM, Hilborn ED. 2016.

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. Direct discharge points or atmospheric deposition source terms can be taken into account. STERNE calculates Eulerian radionuclide dispersion using advection and diffusion equations established offline from hydrodynamic calculations. A radioecological model based on dynamic transfer equations is implemented to evaluate activity concentrations in aquatic organisms. Essential radioecological parameters (concentration factors and single or multicomponent biological half-lives) have been compiled for main radionuclides and generic marine species (fish, molluscs, crustaceans and algae). Dispersion and transfer calculations are performed simultaneously on a 3D grid. Results can be plotted on maps, with possible tracking of spatio-temporal evolution. Post-processing and visualization can then be performed. Copyright © 2015 Elsevier Ltd. All rights reserved.

Mistakes in diagnosing non-accidental injury: 10 years' experience

Wheeler, David M; Hobbs, Christopher J

1988-01-01

Fifty children who were referred to the child abuse team in Leeds over the 10 years 1976-86 with suspected non-accidental injury were found to have conditions which mimicked non-accidental injury. These included impetigo (nine children) and blue spots (five children). Five children who presented with multiple bruising had haemostatic disorders. Eight children had disorders of the bone. Five children had been previously abused physically. Four showed evidence of neglect. One had evidence of non-accidental injury as well as the condition mimicking abuse. It is emphasised that when child abuse is suspected a sensitive and thorough assessment should be carried out by a paediatrician who is experienced in this. ImagesFIG 1 PMID:3133026

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

Radioactive decay data tables: A handbook of decay data for application to radiation dosimetry and radiological assessments

NASA Astrophysics Data System (ADS)

Kocher, D. C.; Smith, J. S.

Decay data are presented for approximately 500 radionuclides including those occurring naturally in the environment, those of potential importance in routine or accidental releases from the nuclear fuel cycle, those of current interest in nuclear medicine and fusion reactor technology, and some of those of interest to Committee 2 of the International Commission on Radiological Protection for the estimation of annual limits on intake via inhalation and ingestion for occupationally exposed individuals. Physical processes involved in radioactive decay which produce the different types of radiation observed, methods used to prepare the decay data sets for each radionuclide in the format of the computerized evaluated nuclear structure data file, the tables of radioactive decay data, and the computer code MEDLIST used to produce the tables are described. Applications of the data to problems of interest in radiation dosimetry and radiological assessments are considered as well as the calculations of the activity of a daughter radionuclide relative to the activity of its parent in a radioactive decay chain.

Scaling and Multifractality in Road Accidental Distances

NASA Astrophysics Data System (ADS)

Qiu, Tian; Wan, Chi; Zou, Xiang-Xiang; Wang, Xiao-Fan

Accidental distance dynamics is investigated, based on the road accidental data of the Great Britain. The distance distribution of all the districts as an ensemble presents a power law tail, which is different from that of the individual district. A universal distribution is found for different districts, by rescaling the distribution functions of individual districts, which can be well fitted by the Weibull distribution. The male and female drivers behave similarly in the distance distribution. The multifractal characteristic is further studied for the individual district and all the districts as an ensemble, and different behaviors are also revealed between them. The accidental distances of the individual district show a weak multifractality, whereas of all the districts present a strong multifractality when taking them as an ensemble.

Accidental injuries are a leading cause of morbidity and mortality in the United States. Hearing problems may be associated with an increased risk for such injuries. To investigate associations between hearing difficulty and risk of accidental injuries among US adults. Cross-sectional analysis of responses of a nationally representative sample of 232.2 million individuals 18 years or older who participated in the National Health Interview Survey from 2007 to 2015 and responded to the questions related to the hearing and injury modules. The main outcome variable was accidental injury in the preceding 3 months. Hearing status was self-reported as "excellent," "good," "a little trouble," "moderate trouble," "a lot of trouble," and "deaf." Prevalence of accidental injuries was analyzed based on demographic characteristics and hearing status. Odds ratios (ORs) and 95% CIs for injuries adjusted for demographics were calculated for degrees of hearing difficulty. A secondary outcome was association of hearing status with type of injury and was classified as driving related, work related, or leisure/sport related. Of 232.2 million US adults, 120.2 million (51.7%) were female, and 116.3 million (50.1%) considered their hearing to be less than excellent. Accidental injuries occurred in 2.8% of survey respondents. In comparison with normal-hearing adults (those with self-rated excellent or good hearing), the odds of accidental injury were higher in those with a little trouble hearing (4.1%; OR, 1.6; 95% CI, 1.5-1.8), moderate trouble hearing (4.2%; OR, 1.7; 95% CI, 1.4-1.9), and a lot of trouble hearing (4.8%; OR, 1.9; 95% CI, 1.6-2.3). Work- and leisure-related injuries were more prevalent among those with self-perceived hearing difficulty. Multivariate analysis, adjusted for age and sex, revealed leisure-related injuries was most consistently associated with various degrees of hearing difficulty. Odds ratios were 1.2 (95% CI, 1.0-1.4) in those with a little trouble hearing, 1.4 (95% CI, 1.1-1.9) in those with moderate trouble hearing, and 1.5 (95% CI, 1.1-2.2) in those with a lot of trouble hearing. Hearing difficulty is significantly associated with accidental injury, especially injury related to work or leisure. Increased awareness about hearing difficulty and its proper screening and management may assist in decreasing accidental injury.

Objective: This study examined the risk of accidental events in older adults prescribed a sedating antidepressant, long-acting benzodiazepine, short-acting benzodiazepine, and nonbenzodiazepine, relative to a reference group (selective melatonin receptor agonist). Methods: This was a retrospective cohort analysis of older adults (≥65 years) with newly initiated pharmacological treatment of insomnia. Data were collected from the Thomson MarketScan® Medicare Supplemental and Coordination of Benefits databases (January 1, 2000, through June 30, 2006). Probit models were used to evaluate the probability of an accidental event. Results: Data were analyzed for 445,329 patients. Patients taking a long-acting benzodiazepine (1.21 odds ratio [OR]), short-acting benzodiazepine (1.16 OR), or nonbenzodiazepine (1.12 OR) had a significantly higher probability of experiencing an accidental event during the first month following treatment initiation compared with patients taking the reference medication (P < 0.05 for all). A significantly higher probability of experiencing an accidental event was also observed during the 3-month period following the initiation of treatment (1.62 long-acting benzodiazepine, 1.60 short-acting benzodiazepine, 1.48 nonbenzodiazepine, and 1.56 sedating antidepressant; P < 0.05). Conclusions: Older adults taking an SAD or any of the benzodiazepine receptor agonists appear to have a greater risk of an accidental event compared with a reference group taking an MR.

A simple core-shell two-dimensional photonic crystal is studied where the triangular lattice symmetry and the C₆ point group symmetry give rich physics in accidental touching points of photonic bands. We systematically evaluate different types of accidental nodal points at the Brillouin zone center for transverse-magnetic harmonic modes when the geometry and permittivity of the core-shell material are continuously tuned. The accidental nodal points can have different dispersions and topological properties (i.e., Berry phases). These accidental nodal points can be the critical states lying between a topological phase and a normal phase of the photonic crystal. They are thus very important for the study of topological photonic states. We show that, without breaking time-reversal symmetry, by tuning the geometry of the core-shell material, a phase transition into the photonic quantum spin Hall insulator can be achieved. Here the "spin" is defined as the orbital angular momentum of a photon. We study the topological phase transition as well as the properties of the edge and bulk states and their application potentials in optics.

Electrical Fatalities in Northern Ireland

A review of autopsy reports in cases of electrocution in Northern Ireland revealed that there were 50 accidental electrocutions and 9 suicidal electrocutions over a 22 year period (1982 – 2003). No cases of homicidal electrocution were detected in this jurisdiction. Analysis of the cohort of accidental electrocutions showed that there was a clear skew towards young and middle-aged male adults with deaths occurring more frequently in the summer months. Almost 60% of individuals were engaged in occupational tasks when they were accidentally electrocuted. High and low voltage-related deaths occurred with similar frequency and electrical appliances were found to be responsible for approximately one third of accidental electrocutions. The potential hazards of electricity must continue to be stressed in public safety campaigns if these relatively uncommon but tragic deaths are to be prevented. PMID:19252729

We report the case of a 77-year-old man, in whom accidental hypothermia was secondary to prolonged immobilization and malnutrition. The electrocardiogram showed typical Osborn waves, which disappeared with the rewarming of the patient. The diagnosis of hypothermia is easy in patients with a history of prolonged exposure to a cold environment but accidental hypothermia may also occur as a consequence of prolonged immobilization and malnutrition. ECG analysis is very important for a correct and fast diagnosis.

Composite accidental axions

Redi, Michele; Sato, Ryosuke

2016-05-01

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.

To investigate the impact of narrative verdicts on suicide statistics among 10-19-year-olds; to identify the number and rate of suicide and accidental deaths, particularly in 10-14-year-olds. National cohort study. England and Wales. Mid-year population estimates from the Office for National Statistics (ONS) were used to calculate rates per 100,000 population for suicide (undetermined and suicide verdicts) and accidental deaths (poisoning, hanging) for those aged 10-14 and 15-19. Trends in rates over time (2001-2010) were investigated using Poisson regression. Interaction tests were carried out to determine differences in trends between the two time periods (2001-2005 and 2006-2010). There were 1523 suicides (2.25/100,000). Suicide rates were highest in those aged 15-19 years (4.04/100,000) and in males (3.14/100,000). Between 2001 and 2010, rates significantly decreased among those aged 15-19 years (incidence rate-ratio (IRR): 0.95; 95% CI 0.93 to 0.97), with no change in rates of accidental deaths (IRR: 1.01, 95% CI 0.95 to 1.07). However, there was a significant interaction between the two time periods for accidental poisonings (2001-2005: IRR: 0.79 (95% CI 0.69 to 0.91); 2006-2010: IRR: 1.01 (95% CI 0.89 to 1.15), interaction p=0.012) and accidental hangings (2001-2005: IRR: 0.93 (95% CI 0.76 to 1.14); 2006-2010: IRR: 1.25 (95% CI 1.04 to 1.49), interaction=0.01) Undetermined deaths significantly decreased among females aged 15-19 yeras (IRR: 0.93; 95% CI 0.88 to 0.98). There were no significant trends among 10-14-year-olds. Rates of suicide are higher among older adolescents and males. There was a significant fall in suicide rates in males aged 15-19 years that was not accounted for by changes in rates of accidental death. The absence of a significant trend in suicide or accidental deaths in those aged 10-14 years may have been the result of small numbers. However, monitoring should continue to identify longitudinal trends in all young people.

The accidental mentor: Australian rural nurses developing supportive relationships in the workplace.

2007-01-01

Like the fictional 'Accidental Tourist', an author who does not plan to write about travel, the accidental mentor is an experienced rural nurse who does not plan to be a mentor, and yet assumes that role with new or novice rural nurses as a result of them encountering a critical incident. Accidental mentoring is a short-term relationship that provides support for the new or novice nurse in managing the incident, while maintaining their level of confidence. This article describes the findings from a constructivist grounded theory study that examined Australian rural nurses' experiences of mentoring, including evidence for a new concept of mentoring - accidental mentoring. Constructivist grounded theory is a research methodology that focuses on issues of importance for participants around an area of common interest - in this case Australian rural nurse mentoring. In this study, seven participants were interviewed, generating nine transcripts. These were analysed using a process of concurrent data generation and analysis. In addition, the literature regarding rural nurse workforce and mentoring was incorporated as a source of data, using collective frame analysis. Rural nurses live their work, which predisposes them to developing supportive relationships with new or novice rural nurses. Supportive relationships range from preceptoring, to accidental mentoring, mentoring and deep friendship, depending on the level of trust and engagement that is established between the partners and the amount of time they spend together. Accidental mentoring is a short-term relationship that is prompted by experienced rural nurses observing a new or novice rural nurse experiencing a critical incident. Findings are presented that illustrate a new concept of accidental mentoring not present in the current literature around nurse mentoring. A series of recommendations are included that suggest strategies for improved rural nurse retention as an outcome of recognising and developing such supportive relationships in the workplace. Strategies include: performance review and development processes that account for all forms of supportive relationships conducted in the workplace; recognising the importance of developing supportive relationships and allocating time for these; and continuing professional development designed to meet local needs for developing a culture of support in the workplace.

A case of pediatric age anticholinergic intoxication due to accidental Datura stramonium ingestion admitting with visual hallucination.

2014-01-01

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.

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.

Accidents are a preventable cause of death. Unfortunately it accounts for a large number of deaths in many societies. In Kuwait, road traffic accidents (RTA) is the leading cause of death in young people. The study investigated the patterns of accidental deaths in Kuwait, one of the Gulf States which incorporates a wide variety of multi-ethnic communities. The study was retrospective from 2003-2009. Data of forensic cases were collected from the general department of criminal evidence (GDCE) in the ministry of interior (MOI).We attempted to find out causes of accidental death and the prevelance of each cause. Furthermore, the relationship of demographic factors (eg. Age, sex, marital status and nationality) with each cause of accidental death in Kuwait were studied. The material of this study constituted a total of 4886 reported accidental deaths referred for Medico-legal examination. Road traffic accidents was by far the most prevalent cause of death (64.6%) followed by fall from height (13.1%). Poisoning and mine explosions were amongst the least common causes. The government of Kuwait needs to take strong measures to promote safety in the workplace and households by educational campaigns.

Accidental Falls Among Geriatric Patients: Can More Be Prevented?

The potential for accidental falls among geriatric patients is of mounting concern. Two hundred forty-one accidental falls over a 12-month period at the VA Medical Center were analyzed retrospectively and the literature reviewed in order to highlight factors that have bearing on the incidence and severity of falls. If a patient's potential for falling could be identified through a grading system based on these premonitory features, preventive measures might be more clearly focused where needed to reduce this frequent hazard in our hospital population.

The authors from the Florence Forensic Department present a case that demonstrates the paradigms attached to accidental deaths while performing autoerotic maneuvers. The incidents of such practices are underestimated and are only the tip of the iceberg since they do not represent the cases that are never reported due to successful practice. After analyzing the statistic data, the authors describe the case and discuss about the element that prove the accidental nature of the death and the importance of the correct application of forensic methodology at the scene and in the mortuary.

Rates of suicide and accidental or violent death remain high in HIV-positive populations despite significantly improved prognosis since the introduction of cART. We conducted a nested case-control study of suicide and accidental or violent death in the Australian HIV Observational Database (AHOD) between January 1999 and March 2012. For each case, 2 controls were matched by clinic, age, sex, mode of exposure and HIV-positive date to adjust for potential confounding by these covariates. Risk of suicide and accidental or violent death was estimated using conditional logistic regression. We included 27 cases (17 suicide and 10 violent/accidental death) and 54 controls. All cases were men who have sex with men (MSM) or MSM/ injecting drug use (IDU) mode of exposure. Increased risk was associated with unemployment (Odds Ratio (OR) 5.86, 95% CI: 1.69-20.37), living alone (OR 3.26, 95% CI: 1.06-10.07), suicidal ideation (OR 6.55, 95% CI: 1.70-25.21), and >2 psychiatric/cognitive risk factors (OR 4.99, 95% CI: 1.17-30.65).

CD4 cell count ≥500 cells/µL remained a significant predictor of reduced risk (OR 0.15, 95% CI: 0.03-0.70) in a multivariate model adjusted for employment status, accommodation status and HIV-positive date. After adjustment for psychosocial factors, the immunological status of HIV-positive patients contributed to the risk of suicide and accidental or violent death. The number of psychiatric/cognitive diagnoses contributed to the level of risk but many psychosocial factors were not individually significant. These findings indicate a complex interplay of factors associated with risk of suicide and accidental or violent death.

The aim of the study was to compare the cervical spine (c-spine) pattern of injury and outcomes in children below 3 y with a head injury from confirmed inflicted versus accidental trauma. After Institutional Review Board approval, data were prospectively collected between July 2011 and January 2016. Inclusion criteria were age below 3 y, a loss of consciousness, and any one of the following initial head computed tomography (CT) findings (subdural hematoma, intraventricular, intraparenchymal, subarachnoid hemorrhage, or cerebral edema). A protocol of brain and neck magnetic resonance imaging and magnetic resonance angiography was instituted. Brain and neck imaging results, clinical variables, and outcomes were recorded. Data were compared by t-test for continuous and Fisher exact test for categorical variables. 73 children were identified, 52 (71%) with inflicted and 21 (29%) with accidental trauma. The median age was 11 mo; (range: 1-35 mo). Ten (14%) had c-spine injuries, 7/52 (13%) inflicted, and 3/21 (14%) accidental. The mechanism was shaking for all inflicted and motor vehicle accident or pedestrian struck for accidental c-spine injuries. The inflicted group were significantly younger (P = 0.03), had higher Injury Severity Scores (P = 0.02), subdural hematomas (P = 0.03), fractures (P = 0.03), retinal hemorrhages (P = 0.02), brain infarcts (P = 0.01), and required cardiopulmonary resuscitation (P = 0.01). Seven with inflicted trauma died from brain injury (9.5%), one had atlanto-occipital dissociation. Six mortalities (86%) had no c-spine injury. Six with inflicted c-spine injuries survived with neurologic impairment, whereas three with accidental survived without disability, including one atlanto-occipital dissociation. Compared to accidental trauma, young children with inflicted c-spine injuries have more multisystem trauma, long-term disability from brain injury, and an injury pattern consistent with shaking.

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.

Accidental Strangulation Due to Entrapment of Saree in Crop Thrasher Machine in an Elderly Women Working at Agricultural Field.

PubMed

Parchake, Manoj Bhausaheb; Kumre, Vikas; Kachare, Rajesh V

2016-09-01

Strangulation is generally considered as homicidal death and in accidental strangulation circumstantial evidence alone can point toward the accidental nature of incidence. In present case, a 71-year-old woman, wearing a saree (garment worn by traditional women in India) working in agricultural field, got entangled in the crop thrasher machine and got strangled. Immediately, she was taken to the nearest hospital, where she survived for 6 to 8 hours and then died. The autopsy reveals cross ribbon-shaped ligature mark on neck and anterior chest along with 1 puncture wound at the right lateral aspect of the neck. A lack of proper precaution and safety measures at agricultural field are other contributing factors. Accidental strangulation by saree is extremely rare, hence, this case is presented for its rarity and pattern of injury.

Effects of a modified through-mask drinking system (MDS) on fluid intake during exercise in chemical protective gear. Report for January-May 1989

DOE Office of Scientific and Technical Information (OSTI.GOV)

Szlyk, P.C.; Sils, I.V.; Tharion, W.J.

This study was designed to evaluate the effects of a modified through-mask drinking system (MDS) on voluntary fluid consumption. Eighteen male volunteers walked on a treadmill (4.02 km/hr, 0 deg. grade, 50 min/hr for 6 hr) in a climatic chamber (dry bulb=32.6 deg C, wet bulb=17.5 deg C, 20.4% relative humidity, and windspeed=8.05 km/hr, producing a WBGT of 22.1 deg C). Subjects wore chemical protective gear (trousers, jacket, boots, gloves, and M17A1 protective mask) and were randomly assigned one of two through-mask and were randomly assigned one of two through-mask drinking systems: CS (n=9), the current gravity fed system ormore » MDS (n=9), a prototype hand-pump drinking system. Because decontamination of the mask and drinking connections was performed prior to drinking, the overall use of the CS was rated significantly more difficult during both work and rest than the MDS. Failure to decontaminate connections prior to drinking was noted early in the trial in 2 soldiers using the CS suggesting an increase risk of accidental contamination associated with this system. Drinking with the MDS had no measurable adverse effect on hydration status of the test subjects: water intake rate, 0.36 L/hr (CS) and 0.42 L/hr (MDS); sweat rate, 0.63 L/hr (CS) and 0.67 L/hr (MDS); body weight loss, 0.32 %/hr (CS) and 0.31 %/hr (MDS).« less

Accidental falls in hospitalized children: an analysis of the vulnerabilities linked to the presence of caregivers.

2010-06-01

This study stemmed from the data gathered by a research conducted by the coordinator of the Department of Healthcare Services and a group of nurses involved in a research on accidental falls in hospitalized children at the "G. Gaslini" Children's Hospital and Scientific Research Institute in Genoa, Italy. The first retrospective study evaluated the accidental falls in hospitalized children referred to the three-year period 2003-2006, while the second perspective study, referred to the trimester March-May 2007, found that the main cause of falls in children was parent's distraction. The method adopted in the first phase of our study was a proactive risk analysis (The Basics of Healthcare Failure Mode and Effect Analysis), identified in the first place by the VA National Centre for Patient Safety and applied to the "Child and parent hospital admission process". This proactive risk analysis has proven to be very effective in preventing the risk of accidental falls in hospitalized children through effective communication and educational interventions. The second phase of our study consisted of two Focus Groups for accidental traumatic events. The analysis of the results of the study showed how effective communication is instrumental, not only to have a better awareness of the children and their parents during their stay in hospital, but also to implement educational sessions on prevention to reduce the risk of accidental traumatic events. The present study contributes to improve safety and the quality of care by motivating nurses to keep their attention high on falls in hospitalized children, by monitoring and the development of new risk assessment tools.

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 < 5 min, yet 51% of patients (95% CI 43-60%) experienced distress and 41% (95% CI 33-50%) suffered longer-term adverse effect. Distress and longer-term harm occurred across the full range of experiences but were particularly likely when the patient experienced paralysis (with or without pain). The patient's interpretation of what is happening at the time of the awareness seemed central to later impact; explanation and reassurance during suspected accidental awareness during general 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.

Hemodialysis as a treatment of severe accidental hypothermia.

PubMed

Caluwé, Rogier; Vanholder, Raymond; Dhondt, Annemieke

2010-03-01

We describe a case of severe accidental hypothermia (core body temperature 23.2 degrees C) successfully treated with hemodialysis in a diabetic patient with preexisting renal insufficiency. Consensus exists about cardiopulmonary bypass as the treatment of choice in cases of severe accidental hypothermia with cardiac arrest. Prospective randomized controlled trials comparing the different rewarming modalities for hemodynamically stable patients with hypothermia, however, are lacking. In our opinion, the choice of a rewarming technique should be patient tailored, knowing that hemodialysis is an efficient, minimally invasive, and readily available technique with the advantage of providing electrolyte support.

Yalcin, Serhat; Aktas, Irem; Emes, Yusuf; Atalay, Belir

2008-03-01

Removal of third molars is one of the most common surgical procedures performed in oral and maxillofacial surgery. This procedure may result in a number of major and minor complications. Accidental displacement of impacted third molars is a complication that occasionally occurs during these operations, but accidental displacement of a high-speed handpiece bur has never been reported in literature before. The aim of this article is to present a rare and previously unreported case of a foreign body in the submandibular space and to review the possible complications seen after third molar surgery.

Runge-Lenz vector, accidental SU(2) symmetry, and unusual multiplets for motion on a cone

DOE Office of Scientific and Technical Information (OSTI.GOV)

Al-Hashimi, M.H.; Wiese, U.-J.

2008-01-15

We consider a particle moving on a cone and bound to its tip by 1/r or harmonic oscillator potentials. When the deficit angle of the cone divided by 2{pi} is a rational number, all bound classical orbits are closed. Correspondingly, the quantum system has accidental degeneracies in the discrete energy spectrum. An accidental SU(2) symmetry is generated by the rotations around the tip of the cone as well as by a Runge-Lenz vector. Remarkably, some of the corresponding multiplets have fractional 'spin' and unusual degeneracies.

Background Accidental non-fire-related (ANFR) carbon monoxide (CO) poisoning is a cause of fatalities and hospital admissions. This is the first study that describes the characteristics of ANFR CO hospital admissions in England. Methods Hospital Episode Statistics (HES) inpatient data for England between 2001 and 2010 were used. ANFR CO poisoning admissions were defined as any mention of ICD-10 code T58: toxic effect of CO and X47: accidental poisoning by gases or vapours, excluding ICD-10 codes potentially related to fires (X00-X09, T20-T32 and Y26). Results There were 2463 ANFR CO admissions over the 10-year period (annual rate: 0.49/100 000); these comprised just under half (48.7%) of all non-fire-related (accidental and non-accidental) CO admissions. There was seasonal variability, with more admissions in colder winter months. Higher admission rates were observed in the north of England. Just over half (53%) of ANFR admissions were male, and the highest rates of ANFR admissions were in those aged >80 years. Conclusion The burden of ANFR CO poisoning is preventable. The results of this study suggest an appreciable burden of CO and highlight differences that may aid targeting of public health interventions. PMID:25755248

Single stab injuries.

2018-05-01

Determining the manner of death in cases involving multiple stab injuries from a knife is generally straightforward. The medico-legal investigation of a stabbing death caused by a single stab injury from a knife comprises a smaller but potentially more problematic subset of forensic cases. We reviewed our institute's experience with single stab injuries and endeavored to identify features identified at the post-mortem examination which may aid in the differentiation between cases of homicide, suicide and accidental death. The single stab injury was to the left chest in the majority of deaths from homicide and from suicide. Clothing was nearly always involved in cases of homicide, but was also seen in cases of suicide. The knife was found in situ in 9 of the 11 cases of suicide involving a chest injury, but was not seen in any of the cases of homicide. There were no cases of an accidental single stab death from a knife in our records. Clinical data on accidental stab injuries was sought via a search of the medical records of a major tertiary referral hospital. A single non-fatal case of an accidental single stab injury from a knife was identified after the conclusion of our study period. Accidental stab injuries from a knife causing injury or death are rare.

Prediction of adherence to a gluten-free diet using protection motivation theory among adults with coeliac disease.

PubMed

Dowd, A J; Jung, M E; Chen, M Y; Beauchamp, M R

2016-06-01

Coeliac disease is a chronic autoimmune disease that requires strict adherence to a gluten-free diet. However, strict adherence to a gluten-free diet is difficult, with findings from a recent review suggesting that up to 42% of individuals with coeliac disease do not eat a strict gluten-free diet. The present study aimed to examine psychosocial predictors of adherence (purposeful and accidental) to a gluten-free diet among adults with coeliac disease over a 1-month period. In this longitudinal study, 212 North American adults with coeliac disease completed online questionnaires at two time points, baseline and 1 month later. The results revealed that intentions partially mediated the effects of symptom severity, self-regulatory efficacy, planning and knowledge on purposeful gluten consumption. Intentions did not mediate the effects of severity, response cost, self-regulatory efficacy, planning and knowledge for accidental gluten consumption but, interestingly, self-regulatory efficacy directly predicted fewer accidental incidents of gluten-consumption. These findings delineate the differential psychological processes in understanding accidental and purposeful gluten consumption among adults with coeliac disease and emphasise the importance of bolstering self-regulatory efficacy beliefs to prevent accidental and purposeful consumption of gluten. © 2015 The British Dietetic Association Ltd.

Celiac Disease and Wheat Allergy: A Growing Association?

PubMed

Micozzi, Sarah; Infante, Sonsoles; Fuentes-Aparicio, Victoria; Álvarez-Perea, Alberto; Zapatero, Lydia

2018-05-30

Celiac disease and wheat allergy (WA) are infrequent diseases in the general population, and a combination of the 2 is particularly rare. Celiac disease occurs in around 1% of the general population and WA in around 1% of all children. We report 2 patients with celiac disease and a gluten-free diet who developed WA consistent in anaphylaxis and an eyelid angioedema, respectively, through accidental wheat exposure. A serum study and an intestinal biopsy confirmed celiac disease. Both patients were studied with a skin prick test and serum-specific IgE, with a diagnosis of WA. In patients with celiac disease, the trace amounts of cereals present in gluten-free food could act as a sensitization factor, and probably patients with persistent symptoms (despite a gluten-free diet) are experiencing WA symptoms rather than celiac disease symptoms. The number of patients diagnosed with celiac disease has increased in the recent decades: the association between celiac disease and WA, exceedingly rare to date, could increase as well, prompting special attention to the possibility of inadvertent intake of cereals. © 2018 S.

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.

Risk factors for unnatural death: Fatal accidental intoxication, undetermined intent and suicide: Register follow-up in a criminal justice population with substance use problems.

PubMed

Olsson, Martin O; Bradvik, Louise; Öjehagen, Agneta; Hakansson, Anders

2016-05-01

Risk factors for suicide and fatal accidental intoxication are extensively studied, while risk factors for intoxications/injuries of undetermined intent are less well known. The latter have shown an overlap with suicides, but also with fatal accidental intoxications. The objective was to analyze potential differences and similarities in the patterns of risk factors for accidental intoxications, injuries/intoxications with undetermined intent, and suicides, respectively. A follow-up register study was conducted, using data from ASI interviews with clients in the criminal justice system in Sweden (n=6744), followed in the National Causes of Death Register. A set of risk factors from the ASI interview were tested in bivariate analysis with the respective cause of death, yielding significant risk factors further analyzed in three Cox regression models. In Cox regression analyses, death from fatal accidental intoxication was associated with male gender (HR 4.09), use of heroin (HR 2.86), and use of cannabis (HR 1.94), and death from intoxication/injury of undetermined intent was associated with use of heroin (HR 3.48), binge drinking of alcohol (HR 2.46) and previous psychiatric hospitalization (HR 2.41), while negatively associated with depression (HR 0.33). Death from suicide was associated with previous suicide attempts (HR 2.78) and use of sedatives (HR 2.17). In this population of criminal justice clients with reported substance use problems, fatal injuries/intoxications with undetermined intent - like fatal accidental intoxications - appear to be associated with substance use variables, and cannot readily be assumed to represent the same background factors as suicide.

Are pre-hospital deaths from accidental injury preventable?

PubMed Central

Hussain, L. M.; Redmond, A. D.

1994-01-01

OBJECTIVE--To determine what proportion of pre-hospital deaths from accidental injury--deaths at the scene of the accident and those that occur before the person has reached hospital--are preventable. DESIGN--Retrospective study of all deaths from accidental injury that occurred between 1 January 1987 and 31 December 1990 and were reported to the coroner. SETTING--North Staffordshire. MAIN OUTCOME MEASURES--Injury severity score, probability of survival (probit analysis), and airway obstruction. RESULTS--There were 152 pre-hospital deaths from accidental injury (110 males and 42 females). In the same period there were 257 deaths in hospital from accidental injury (136 males and 121 females). The average age at death was 41.9 years for those who died before reaching hospital, and their average injury severity score was 29.3. In contrast, those who died in hospital were older and equally likely to be males or females. Important neurological injury occurred in 113 pre-hospital deaths, and evidence of airway obstruction in 59. Eighty six pre-hospital deaths were due to road traffic accidents, and 37 of these were occupants in cars. On the basis of the injury severity score and age, death was found to have been inevitable or highly likely in 92 cases. In the remaining 60 cases death had not been inevitable and airway obstruction was present in up to 51 patients with injuries that they might have survived. CONCLUSION--Death was potentially preventable in at least 39% of those who died from accidental injury before they reached hospital. Training in first aid should be available more widely, and particularly to motorists as many pre-hospital deaths that could be prevented are due to road accidents. PMID:8173428

Life-cycle assessment is usually based on regular discharges that occur at a more or less constant rate. Nevertheless, the more factors that are taken into account in the LCA the better picture it gives on the environmental aspects of a product. In this study an approach to incorporate accidental releases into a products` life-cycle assessment was developed. In this approach accidental releases are divided into two categories. The first category consists of those unplanned releases which occur with a predicted level and frequency. Due to the high frequency and small release size at a time, these accidental releases can bemore » compared to continuous emissions. Their global impacts are studied in this approach. Accidental releases of the second category are sudden, unplanned releases caused by exceptional situations, e.g. technical failure, action error or disturbances in process conditions. These releases have a singular character and local impacts are typical of them. As far as the accidental releases of the second category are concerned, the approach introduced in this study results in a risk value for every stage of a life-cycle, the sum of which is a risk value for the whole life-cycle. Risk value is based on occurrence frequencies of incidents and potential environmental damage caused by releases. Risk value illustrates the level of potential damage caused by accidental releases related to the system under study and is meant to be used for comparison of these levels of two different products. It can also be used to compare the risk levels of different stages of the life-cycle. An approach was illustrated using petrol as an example product. The whole life-cycle of petrol from crude oil production to the consumption of petrol was studied.« less

Dong, Chaoqun; Gong, Shumei; Jiang, Liping; Deng, Guanghui; Liu, Xiaohong

2015-01-01

The primary goals of this study, were to identify the posttraumatic growth (PTG) level of accidentally injured Chinese patients shortly after an accident occurred and to determine whether cognitive processing, self-disclosure, and psychosocial resources predicted PTG. A total of 232 patients were recruited from two public hospitals in Shanghai within the first three months of an accidental injury. Patients completed self-report questionnaires to assess severity of injury, cognitive processing, self-disclosure, psychosocial resources, and PTG. Patients reported a mid-low level of PTG (M = 50.38, SD = 18.12) in the short length of time post-injury. Hierarchical regression analysis indicated that subjective accident severity, deliberate rumination, perceived social support, and attitude towards disclosure were strong predictors of PTG. A moderating role of self-disclosure between intrusive rumination and PTG was identified. These findings support an interaction effect of rumination and self-disclosure on PTG and have implications for early intervention of accidentally injured patients.

Background Rates of suicide and accidental or violent death remain high in HIV-positive populations despite significantly improved prognosis since the introduction of cART. Methods We conducted a nested case-control study of suicide and accidental or violent death in the Australian HIV Observational Database (AHOD) between January 1999 and March 2012. For each case, 2 controls were matched by clinic, age, sex, mode of exposure and HIV-positive date to adjust for potential confounding by these covariates. Risk of suicide and accidental or violent death was estimated using conditional logistic regression. Results We included 27 cases (17 suicide and 10 violent/accidental death) and 54 controls. All cases were men who have sex with men (MSM) or MSM/ injecting drug use (IDU) mode of exposure. Increased risk was associated with unemployment (Odds Ratio (OR) 5.86, 95% CI: 1.69–20.37), living alone (OR 3.26, 95% CI: 1.06–10.07), suicidal ideation (OR 6.55, 95% CI: 1.70–25.21), and >2 psychiatric/cognitive risk factors (OR 4.99, 95% CI: 1.17–30.65). CD4 cell count of >500 cells/µL (OR 0.25, 95% CI: 0.07–0.87) and HIV-positive date ≥1990 (1990–1999 (OR 0.31, 95% CI: 0.11–0.89), post-2000 (OR 0.08, 95% CI: 0.01–0.84)) were associated with decreased risk. CD4 cell count ≥500 cells/µL remained a significant predictor of reduced risk (OR 0.15, 95% CI: 0.03–0.70) in a multivariate model adjusted for employment status, accommodation status and HIV-positive date. Conclusions After adjustment for psychosocial factors, the immunological status of HIV-positive patients contributed to the risk of suicide and accidental or violent death. The number of psychiatric/cognitive diagnoses contributed to the level of risk but many psychosocial factors were not individually significant. These findings indicate a complex interplay of factors associated with risk of suicide and accidental or violent death. PMID:24586519

2012-01-01

On the basis of graphic models of the human response to environmental factors, two main types of complex quantitative influence as well as interrelation between determined effects at the level of an individual, and stochastic effects on population were revealed. Two main kinds of factors have been suggested to be distinguished. They are essential factors and accidental factors. The essential factors are common for environment. The accidental factors are foreign for environment. The above two kinds are different in approaches of hygienic standardization Accidental factors need a dot-like approach, whereas a two-level range approach is suitable for the essential factors.

Metastatic angiosarcoma of the spleen after accidental radiation exposure: a case report.

PubMed

Geffen, D B; Zirkin, H J; Mermershtain, W; Cohen, Y; Ariad, S

1998-04-01

Angiosarcoma is a rare malignant tumor arising from endothelial cells of blood vessels or lymphatic channels. Therapeutic irradiation, thoriumdioxide administration, pyothorax, and polyvinyl chloride exposure have been shown to be predisposing factors for developing angiosarcoma. Accidental radiation exposure has not been associated with angiosarcoma. We present an unusual case of angiosarcoma of the spleen, with metastases to bone, liver, breast, and bone marrow, in a woman who lived near the Chernobyl nuclear facility in the former Soviet Union at the time of the reactor accident in 1986. To the best of our knowledge, this is the first report of metastatic angiosarcoma after accidental radiation exposure.

Resolution of electroconvulsive therapy refractory major depressive disorder with unintentional hypoglycemic seizure: a case report.

We report a 74-year-old white woman with type 1 diabetes and major depressive disorder refractory to multiple medications who received 15 electroconvulsive therapy treatments with minimal improvement. After an accidental hypoglycemic seizure, the patient's symptoms completely resolved. In conclusion, the present case reveals an instance where electroconvulsive therapy-induced seizures appeared to be minimally effective, whereas a single accidental hypoglycemia-induced seizure was incredibly effective for the resolutions of depressive symptoms. Although this case presents a single efficacious use of accidental insulin coma therapy, the applicability is limited because of the known risks of insulin coma therapy.

Accidental degeneracies in nonlinear quantum deformed systems

2011-09-01

We construct a multi-parameter nonlinear deformed algebra for quantum confined systems that includes many other deformed models as particular cases. We demonstrate that such systems exhibit the property of accidental pairwise energy level degeneracies. We also study, as a special case of our multi-parameter deformation formalism, the extension of the Tamm-Dancoff cutoff deformed oscillator and the occurrence of accidental pairwise degeneracy in the energy levels of the deformed system. As an application, we discuss the case of a trigonometric Rosen-Morse potential, which is successfully used in models for quantum confined systems, ranging from electrons in quantum dots to quarks in hadrons.

To explore the effect of a school-family-individual (SFI) multi-level education intervention model on knowledge and attitudes about accidental injuries among school-aged children to improve injury prevention strategies and reduce the incidence of pediatric injuries. The random sample of rural school-aged children were recruited by using a multistage, stratified, cluster sampling method in Zunyi, Southwest China from 2012 to 2014, and 2342 children were randomly divided into intervention and control groups. Then children answered a baseline survey to collect knowledge and attitude scores (KAS) of accidental injuries. In the intervention group, children, their parents/guardians and the school received a SFI multi-level education intervention, which included a children's injury-prevention poster at schools, an open letter about security instruction for parents/guardians and multiple-media health education (Microsoft PowerPoint lectures, videos, handbooks, etc.) to children. Children in the control group were given only handbook education. After 16 months, children answered a follow-up survey to collect data on accidental injury types and accidental injury-related KAS for comparing the intervention and control groups and baseline and follow-up data. The distribution of gender was not significantly different while age was different between the baseline and follow-up survey. At baseline, the mean KAS was lower for the intervention than control group (15.37 ± 3.40 and 18.35 ± 5.01; p < 0.001). At follow-up, the mean KAS was higher for the intervention than control group (21.16 ± 3.05 and 20.02 ± 3.40; p < 0.001). The increase in KAS in the intervention and control groups was significant (p < 0.001; KAS: 5.79 vs. 1.67) and suggested that children's injury-related KAS improved in the intervention group. Moreover, the KAS between the groups differed for most subtypes of incidental injuries (based on International Classification of Diseases 10, ICD-10) (p < 0.05). Before intervention, 350 children had reported their accident injury episodes, while after intervention 237 children had reported their accidental injury episodes in the follow-up survey. SFI multi-level education intervention could significantly increase KAS for accidental injuries, which should improve children's prevention-related knowledge and attitudes about such injuries. It should help children change their risk behaviors and reduce the incidence of accidental injuries. Our results highlight a new intervention model of injury prevention among school-aged children.

Accidental non-fire-related (ANFR) carbon monoxide (CO) poisoning is a cause of fatalities and hospital admissions. This is the first study that describes the characteristics of ANFR CO hospital admissions in England. Hospital Episode Statistics (HES) inpatient data for England between 2001 and 2010 were used. ANFR CO poisoning admissions were defined as any mention of ICD-10 code T58: toxic effect of CO and X47: accidental poisoning by gases or vapours, excluding ICD-10 codes potentially related to fires (X00-X09, T20-T32 and Y26). There were 2463 ANFR CO admissions over the 10-year period (annual rate: 0.49/100 000); these comprised just under half (48.7%) of all non-fire-related (accidental and non-accidental) CO admissions. There was seasonal variability, with more admissions in colder winter months. Higher admission rates were observed in the north of England. Just over half (53%) of ANFR admissions were male, and the highest rates of ANFR admissions were in those aged >80 years. The burden of ANFR CO poisoning is preventable. The results of this study suggest an appreciable burden of CO and highlight differences that may aid targeting of public health interventions. © The Author 2015.

1998-02-01

Chimpanzees were tested for their ability to discriminate between accidental/inadvertent and intentional actions with equivalent adverse consequences. Subjects were first trained to `point' to human trainers in order to receive food rewards. In Experiment 1, six 5-year-old subjects were alternately presented with two unfamiliar human actors. In condition 1, each actor either started to hand a cup of juice to the trainer but then pulled it back and intentionally poured it onto the floor, or accidentally spilled it while handing it to the trainer. In condition 2, the actors either accidentally spilled it as above, or aggressively threw the juice onto the floor. The subjects were then presented with both actors and were allowed to choose between them. In Experiment 2, seven 6-7-year-old chimpanzees were confronted with unfamiliar actors who either (a) intentionally withheld and consumed food intended for the subjects, (b) attempted to hand the intended food to the subjects but were victimized by a third party who consumed the food, or (c) always succeeded in delivering the food to the subjects. In general, the subjects showed little evidence of using the accidental/inadvertent versus intentional distinction in their choices between the actors, although they did display some evidence of favoring the actor involved in the most passive role in both conditions in Experiment 1.

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.

Bittering agents in the prevention of accidental poisoning: children's reactions to denatonium benzoate (Bitrex).

PubMed Central

Sibert, J R; Frude, N

1991-01-01

The responses of young children to Denatonium Benzoate (Bitrex) were observed, in order to assess the potential of this bittering agent in the prevention of accidental poisoning. Thirty-three children aged 17-36 months were offered orange juice containing Bitrex (in a concentration of 10 parts per million). Of the 30 children who took some of this juice, only seven were willing to take more than 10 gm. A variety of negative verbal and non-verbal responses were noted. It is suggested that the highly unpalatable nature of Bitrex makes this compound a useful additive that could well prevent accidental poisoning from household products of mild to moderate toxicity.

EPIDEMIOLOGY OF ACCIDENTAL POISONING

PubMed Central

Bissell, D. M.; McInnes, Robert S.

1960-01-01

In San Jose, California, studies of cases of accidental poisoning showed that the greatest hazard was to children 1 through 3 years of age. Drugs accounted for half the cases, household products for another third, and insecticides and rodenticides and others for the remainder. Most often poison material was within easy reach of the children. An analysis of families in which an accident occurred indicated that accidental poisoning might happen to any family. Since there was little after-effect of poisoning in cases in which treatment was obtained promptly, education directed toward getting prompt treatment seems most advisable. Community agencies interested in poison control need to focus their attention on parents of pre-school children. PMID:13801023

In the case of accidental release of Uranium-238 (238U) radionuclides in a nuclear facility or in the environment, internal contamination by either acute or chronic exposure has the potential to induce both radiological and chemical toxic effects. A study was conducted to estimate the 238U radionuclide concentration in the long beans using Induced Coupled Mass Plasma-Spectrometry (ICP-MS). 238U radionuclide is a naturally occurring radioactive material that can be found in soil and can be transferred to the long bean (Vigna unguiculata subsp. Sesquapedalis) directly or indirectly via water or air. Kidney and liver are the major sites of deposition of 238U radionuclide. The obtained dose exposed in the liver and kidney is used to assess the safety level for public intake of 238U radionuclide from the consumption of long beans. The concentration of 238U radionuclide measured in long bean samples was 0.0226 ± 0.0009 mg/kg. Total activity of 238U radionuclide was 0.0044 ± 0.0002 Bq/day with the daily intake of 0.3545 ± 0.0143 µg/day and the annual committed effective dose due to ingestion of 238U radionuclide in long beans was 0.2230 ± 0.0087 µSv/year. The committed equivalent dose of 238U radionuclide from the assessment in the liver and kidney are 0.4198 ± 0.0165 nSv and 10.9335 ± 0.4288 nSv. The risk of cancer of 238U radionuclide was determined to be (86.0466 ± 3.3748) × 10-9. Thus, the results concluded that 238U radionuclide in local long beans was in the permitted level and safe to consume without posing any significant radiological threat to population.

2009-01-01

This study explores and describes factors that persons with multiple sclerosis (MS) perceive as being related to accidental falls. A qualitative content analysis with primarily deductive approach was conducted using the International Classification of Functioning, Disability and Health. Twelve persons with MS, and identified as fallers, were interviewed. Factors perceived to cause accidental falls that had not previously been targeted in MS populations in relation to falls were identified as divided attention, reduced muscular endurance, fatigue and heat sensitivity. Previously reported risk factors such as changed gait pattern, limited walking ability, impaired proprioception, vision and spasticity were supported. Activities involving walking, recreation and leisure, maintaining and changing body position, lifting or carrying, taking care of the home, washing the body, moving around, preparing meals and housekeeping were limited and considered to be risk activities. Supportive persons and assistive device reduced falls, and unsuitable physical environments and climate conditions induced falls. Several preventative strategies were described as partially compensating for the impairments, limitations and restrictions. Investigating accidental falls using the perspective of the patient gave important information about variables not earlier targeted in MS research.

Measuring the visual salience of alignments by their non-accidentalness.

Quantitative approaches are part of the understanding of contour integration and the Gestalt law of good continuation. The present study introduces a new quantitative approach based on the a contrario theory, which formalizes the non-accidentalness principle for good continuation. This model yields an ideal observer algorithm, able to detect non-accidental alignments in Gabor patterns. More precisely, this parameterless algorithm associates with each candidate percept a measure, the Number of False Alarms (NFA), quantifying its degree of masking. To evaluate the approach, we compared this ideal observer with the human attentive performance on three experiments of straight contours detection in arrays of Gabor patches. The experiments showed a strong correlation between the detectability of the target stimuli and their degree of non-accidentalness, as measured by our model. What is more, the algorithm's detection curves were very similar to the ones of human subjects. This fact seems to validate our proposed measurement method as a convenient way to predict the visibility of alignments. This framework could be generalized to other Gestalts.

An alternative approach for computing seismic response with accidental eccentricity

NASA Astrophysics Data System (ADS)

Fan, Xuanhua; Yin, Jiacong; Sun, Shuli; Chen, Pu

2014-09-01

Accidental eccentricity is a non-standard assumption for seismic design of tall buildings. Taking it into consideration requires reanalysis of seismic resistance, which requires either time consuming computation of natural vibration of eccentric structures or finding a static displacement solution by applying an approximated equivalent torsional moment for each eccentric case. This study proposes an alternative modal response spectrum analysis (MRSA) approach to calculate seismic responses with accidental eccentricity. The proposed approach, called the Rayleigh Ritz Projection-MRSA (RRP-MRSA), is developed based on MRSA and two strategies: (a) a RRP method to obtain a fast calculation of approximate modes of eccentric structures; and (b) an approach to assemble mass matrices of eccentric structures. The efficiency of RRP-MRSA is tested via engineering examples and compared with the standard MRSA (ST-MRSA) and one approximate method, i.e., the equivalent torsional moment hybrid MRSA (ETM-MRSA). Numerical results show that RRP-MRSA not only achieves almost the same precision as ST-MRSA, and is much better than ETM-MRSA, but is also more economical. Thus, RRP-MRSA can be in place of current accidental eccentricity computations in seismic design.

Paediatric femur fractures at the emergency department: accidental or not?

2016-01-01

Only a small proportion of all paediatric fractures is caused by child abuse or neglect, especially in highly prevalent long bone fractures. It can be difficult to differentiate abusive fractures from non-abusive fractures. This article focuses on femoral fractures in young children. Based on three cases, this article presents a forensic evidence-based approach to differentiate between accidental and non-accidental causes of femoral fractures. We describe three cases of young children who were presented to the emergency department because of a suspected femur fracture. Although in all cases, the fracture had a similar location and appearance, the clinical history and developmental stage of the child led to three different conclusions. In the first two cases, an accidental mechanism was a plausible conclusion, although in the second case, neglect of parental supervision was the cause for concern. In the third case, a non-accidental injury was diagnosed and appropriate legal prosecution followed. Any doctor treating children should always be aware of the possibility of child abuse and neglect in children with injuries, especially in young and non-mobile children presenting with an unknown trauma mechanism. If a suspicion of child abuse or neglect arises, a thorough diagnostic work-up should be performed, including a full skeletal survey according to the guidelines of the Royal College of Radiologists and the Royal College of Paediatrics and Child Health. In order to make a good assessment, the radiologist reviewing the skeletal survey needs access to all relevant clinical and social information. PMID:26642309

There are few epidemiological studies about climate change and the effect of temperature variation on health using human thermal indices such as the Physiological Equivalent Temperature (PET) Index in Iran. This study was conducted in Tabriz, the northwest of Iran and Distributed Lag Non-linear Models (DLNM) combined with quasi-Poisson regression models were used to assess the impacts of PET on mortality by using the DLNM Package in R Software. The effect of air pollutants, time trend, day of the week and holidays were controlled as confounders. There was a significant relation between high (30°C, 27°C) and low (-0.8°C, -9.2°C and -14.2°C) PET and total (non-accidental) mortality; and a significant increase in respiratory and cardiovascular deaths in high PET values. Heat stress increased Cumulative Relative Risk (CRR) for total (non-accidental), respiratory and cardiovascular mortality significantly (CRR Non Accidental Death, PET=30°C, lag 0-30 =1.67, 95%CI: 1.31-2.13; CRR Respiratory Death, PET=30°C, lag 0-13 =1.88, 95%CI: 1.30-2.72; CRR Cardiovascular Death, PET=30°C, lag0-30 =1.67 95%CI: 1.16-2.40). Heat stress increases the risk of total (non-accidental), respiratory mortality, but cold stress decreases the risk of total (non-accidental) mortality in Tabriz which is one of the cold cities of Iran.

In the field of forensic footwear examination, it is a widely held belief that patterns of accidental marks found on footwear and footwear impressions possess a high degree of "uniqueness." This belief, however, has not been thoroughly studied in a numerical way using controlled experiments. As a result, this form of valuable physical evidence has been the subject of admissibility challenges. In this study, we apply statistical techniques used in facial pattern recognition, to a minimal set of information gleaned from accidental patterns. That is, in order to maximize the amount of potential similarity between patterns, we only use the coordinate locations of accidental marks (on the top portion of a footwear impression) to characterize the entire pattern. This allows us to numerically gauge how similar two patterns are to one another in a worst-case scenario, i.e., in the absence of a tremendous amount of information normally available to the footwear examiner such as accidental mark size and shape. The patterns were recorded from the top portion of the shoe soles (i.e., not the heel) of five shoe pairs. All shoes were the same make and model and all were worn by the same person for a period of 30 days. We found that in 20-30 dimensional principal component (PC) space (99.5% variance retained), patterns from the same shoe, even at different points in time, tended to cluster closer to each other than patterns from different shoes. Correct shoe identification rates using maximum likelihood linear classification analysis and the hold-one-out procedure ranged from 81% to 100%. Although low in variance, three-dimensional PC plots were made and generally corroborated the findings in the much higher dimensional PC-space. This study is intended to be a starting point for future research to build statistical models on the formation and evolution of accidental patterns.

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.

Nonnatural deaths of adolescents and teenagers: Fulton County, Georgia, 1985-2004.

2008-09-01

Childhood deaths are carefully scrutinized by many different government agencies, fatality review panels, researchers, and other groups. Many such deaths, especially those that involve external causes such as injury and poisoning, are amenable to prevention. Characterizing the causes and circumstances of nonnatural childhood deaths may provide information that is useful for development of prevention strategies and programs. This is a retrospective review of all nonnatural deaths investigated and certified by the Fulton County Medical Examiner involving persons 10 to 19 years of age during the years 1985-2004, inclusive. Cases were identified by searching electronic death investigation files maintained during the study period. Demographic and circumstantial information were tabulated for homicides, suicides, motor-vehicle fatalities, and other accidental deaths, and crude death rates were calculated for each 5-year period during the study. During the 20 year period there were 961 nonnatural deaths among persons 10 to 19 years of age. Most deaths were due to homicide (48%) followed by motor-vehicle fatalities (30%), suicide (12%), and nontraffic accidental fatalities (10%). Black males had the highest death rates among the homicide, suicide, and nontraffic accidental deaths, although the rates for each of these were lower in the most recent 5 year period than the first 5-year period. The number of deaths increased in each category as age increased, and this observation was most marked for homicides and least marked for nontraffic accidental deaths. Firearms were involved in 88% of homicides and 61% of suicides. Most nontraffic accidental deaths were due to water-related accidents, followed by drug and/or alcohol toxicity, fire-related injuries, and accidental firearms injuries. Homicide accounts for almost half of all deaths among persons 10 to 19 years of age. Black males are at particularly high risk for nonnatural death in comparison with other race/sex groups, especially for homicide. If effective firearm fatality prevention strategies and programs could be implemented, data in this study suggests that such a measure alone could cut in half the nonnatural mortality rate in the 10 to 19 year age group in Fulton County. Although homicide and suicide rates have declined, there remains room for improvement in these areas, as is the case for traffic-related and other accidental fatalities.

Suicide and accidental death in Australia's rural farming communities: a review of the literature.

Kennedy, Alison J; Maple, Myfanwy J; McKay, Kathy; Brumby, Susan A

2014-01-01

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 contemporary farming. Suicide rates are also frequently described in relation to lethality and accessibility of means. The limitations of suicide and accidental death data are considerable. While there is consistent reporting of heightened levels of risk for suicide and accidental death in farming communities the limitations of the research remain significant. There are substantial gaps in current knowledge, and the body of research to date lacks clarity, inclusiveness and contextual specificity. Absent from the literature is any investigation of the impact of these frequently preventable deaths on the families and communities in which they occur. Recommendations for future research are suggested.

US Transuranium and Uranium Registries case study on accidental exposure to uranium hexafluoride.

PubMed

Avtandilashvili, Maia; Puncher, Matthew; McComish, Stacey L; Tolmachev, Sergei Y

2015-03-01

The United States Transuranium and Uranium Registries' (USTUR) whole-body donor (Case 1031) was exposed to an acute inhalation of uranium hexafluoride (UF6) produced from an explosion at a uranium processing plant 65 years prior to his death. The USTUR measurements of tissue samples collected at the autopsy indicated long-term retention of inhaled slightly enriched uranium material (0.85% (235)U) in the deep lungs and thoracic lymph nodes. In the present study, the authors combined the tissue measurement results with historical bioassay data, and analysed them with International Commission on Radiological Protection (ICRP) respiratory tract models and the ICRP Publication 69 systemic model for uranium using maximum likelihood and Bayesian statistical methods. The purpose of the analysis was to estimate intakes and model parameter values that best describe the data, and evaluate their effect on dose assessment. The maximum likelihood analysis, which used the ICRP Publication 66 human respiratory tract model, resulted in a point estimate of 79 mg of uranium for the occupational intake composed of 86% soluble, type F material and 14% insoluble, type S material. For the Bayesian approach, the authors applied the Markov Chain Monte Carlo method, but this time used the revised human respiratory tract model, which is currently being used by ICRP to calculate new dose coefficients for workers. The Bayesian analysis estimated that the mean uranium intake was 160 mg, and calculated the case-specific lung dissolution parameters with their associated uncertainties. The parameters were consistent with the inhaled uranium material being predominantly soluble with a small but significant insoluble component. The 95% posterior range of the rapid dissolution fraction (the fraction of deposited material that is absorbed to blood rapidly) was 0.12 to 0.91 with a median of 0.37. The remaining fraction was absorbed slowly, with a 95% range of 0.000 22 d(-1) to 0.000 36 d(-1) and a median of 0.000 31 d(-1). The effective dose per unit intake calculated using the dissolution parameters derived from the maximum likelihood and the Bayesian analyses was higher than the current ICRP dose coefficient for type F uranium by a factor of 2 or 7, respectively; the higher value of the latter was due to use of the revised respiratory tract model. The dissolution parameter values obtained here may be more appropriate to use for radiation protection purposes when individuals are exposed to a UF6 mixture that contains an insoluble uranium component.

A case of an accidental exposure to a veterinary insecticide product formulation.

PubMed

Sidhu, K S; Collisi, M B

1989-02-01

A veterinary technician while opening a package was accidentally exposed to a commercial canned product formulation containing insecticides and solvents. The patient was twice briefly treated and released as an outpatient from 2 different hospitals on the first and second day after the exposure. However, on the fourth day, as some of the symptoms (headache, nausea, vomiting, diarrhea, difficult breathing) persisted, the patient was admitted to another hospital. The patient was treated for exposure to organophosphates and solvents and was released after 13 days. The patient developed diabetes insipidus, a condition which lasted for approximately 1 year. The cause of the temporary development of diabetes insipidus is not understood. There is a need to prevent and minimize such accidental exposures in future.

Electrocution attributed to supernatural forces in the Niger delta region of Nigeria: a report of three cases.

Accidental deaths from electrocution in this environment are sometimes related to charm and witchcraft caused by one's enemies. The aim of this article is to highlight the problems of beliefs and accidental electrocution. We report three cases of accidental electrocution which was believed to be associated with traditional beliefs of witchcraft and charm. Autopsy findings in two cases showed characteristic electric burns (the joule burn which is the area of entry) without obvious organ changes. The third case revealed no burn but investigation of the scene of incidence and other sources of information are consistent with a diagnosis of electrocution. Post mortem examination can assist to dispel misconception and unnecessary belief on cause of death in our community.

To provide guidance to clinicians, the Wilderness Medical Society (WMS) convened an expert panel to develop evidence-based guidelines for the out-of-hospital evaluation and treatment of victims of accidental hypothermia. The guidelines present the main diagnostic and therapeutic modalities and provide recommendations for the management of hypothermic patients.

Martínez-Navarrete, Juan; Loria-Castellanos, Jorge; Nava-Ocampo, Alejandro A

2008-04-01

We present a 1.5-year old, 11 kg, female infant with a history of bronchial hyper-responsiveness who accidentally ingested half of a "Chinese chalk". A day later, the infant showed vomiting, cough, fever, drowsiness, and irritability and her clinical conditions progressively worsened. She was admitted to the emergency department with cough, respiratory distress, and hepatomegaly. It has been reported that the chalk may contain deltamethrin and cypermethrin. The patient was successfully treated with supportive therapy. This report identifies "Chinese chalk" as a potential source of accidental poisoning in children and should be considered as part of the differential diagnoses in the emergency rooms since poisoning with these compounds may be misdiagnosed as organophosphate poisoning due to the presentation of similar symptoms.

In the case of an accidental release of 131I, a system for large-scale monitoring of the population for the radionuclide intake is needed. A monitoring system is required to be capable of measuring adult as well as child subjects across a wide range of ages. Such system has been developed by the National Radiation Protection Institute in Prague (NRPI) and the Evinet company (member of the Nuvia Group). This paper describes the optimisation of the NaI(Tl) detector chosen for this system. The design of the crystal was based on Monte Carlo (MC) simulations, and supported by literature. These simulations examined three different crystal shapes and several dimensions. Based on the MC study, two prototype detectors, with crystal diameters 80 and 73 mm, were manufactured and compared with the crystals having dimensions ∅45×40 mm used for thyroid measurement at NRPI and with a standard NaI(Tl) probe (∅76.2×76.2 mm). The detector with a crystal of 80 mm diameter gave the best results and was chosen for further production.

A case report of a 4-year-old child with glucose-6-phosphate dehydrogenase deficiency: An evidence based approach to nutritional management. Turk J Pediatr 2017; 59: 189-192. The objective was to describe the nutritional management of a 4-year-old child with glucose-6-phosphate dehydrogenase (G6PD) deficiency. A 4-year-old male child, African descent, born from non-consanguineous parents presented with a clinical history of frequent respiratory infections, usually treated with antibiotics. At 30 months of age, G6PD diagnosis was made after eating one portion (40 - 60 g) of fava beans, resulting in severe hemolytic anemia hospitalization for 5 days. Diagnosis was confirmed by G6PD activity measurement. Nutritional counseling was given to avoid dietary oxidative stressors particularly the exclusion of fava beans and accidental ingestion of other similar beans. Dietary intake of high vitamin C containing foods was discouraged and adequate hydration advised. Nutritional management is crucial in preventing acute stress events in patients with G6PD deficiency.

Positive income shocks and accidental deaths among Cherokee Indians: a natural experiment

2011-01-01

Background Several studies in low-income populations report the somewhat counterintuitive finding that positive income gains adversely affect adult health. The literature posits that receipt of a large portion of annual income increases, in the short term, risk-taking behaviour and/or the consumption of health-damaging goods. This work implies the hypothesis that persons with an unexpected gain in income will exhibit an elevated risk of accidental death—the fifth leading cause of death in the USA. We test this hypothesis directly by capitalizing on a natural experiment in which Cherokee Indians in rural North Carolina received discrete lump sum payments from a new casino. Methods We applied Poisson regression to the monthly count of accidental deaths among Cherokee Indians over 204 months spanning 1990–2006. We controlled for temporal patterns in accidental deaths (e.g. seasonality and trend) as well as changes in population size. Results As hypothesized, the risk of accidental death rises above expected levels during months of the large casino payments (relative risk = 2.62; 95% confidence interval = 1.54–4.47). Exploratory analyses of ethnographic interviews and behavioural surveys support that increased vehicular travel and consumption of health-damaging goods may account for the rise in accident proneness. Conclusions Although long-term income gains may improve health in this population, our findings indicate that acute responses to large income gains, in the short term, increase risk-taking and accident proneness. We encourage further investigation of natural experiments to identify causal economic antecedents of population health. PMID:21527447

1995-08-01

An anonymous survey of 149 resident doctors was conducted to estimate the extent of accidental exposures to blood and body fluids of patients over a one-year period. There was a total of 1142 exposures. Ninety-three percent of respondents reported one or more exposure incident(s). Analysis of events and procedures leading to accidental exposures revealed that recapping needles was involved in 17%, suturing accounted for 14%, setting up intravenous lines 11%, cuts with scalpel 9% and phlebotomy 9%. Surgical residents had a threefold greater risk of exposure compared with medicine residents. No trend was found for accidental exposures by level of residency training. Seventy-four percent of the residents used universal precautions 50% or less of the time. Only half of the doctors could recall formal instruction on correct course of action after exposure and 5% of them had as undergraduates hepatitis B vaccine prior to the commencement of venepuncture duties. All but one of the residents' exposures were not reported to the Staff Medical Services Department. The doctor who reported was neither tested for hepatitis B virus or human immunodeficiency virus nor was he properly treated. Only 5 (4.6%) of the contaminating patients were evaluated serologically for their status of these viruses. These data emphasize the need for increased efforts toward improved early and continuing education, prevention and correct management of accidental exposures to blood or body fluids of patients by resident doctors in Nigeria. No recent study exists that exclusively addresses this problem in doctors in tropical Africa.

Background Accidental death in people with epilepsy (PWE) has been described in high income settings where the relative risk of death is known to be higher than in the standard population. Population-based studies of injury deaths among PWE in developing countries are uncommon. Methods A population-based verbal autopsy study in Matlab, Bangladesh, performed at a health and demographic surveillance system site (mean population 223,886 in 142 villages), was used to assess the possible causes of all deaths. All cases of accidental injury (2005–2008) were evaluated and compared between people with and without a diagnosis of epilepsy. Results There were 12 accidental deaths among PWE (8 female, age range 12–58 years old) out of a total of 316 deaths due to accidental injuries (3.8% of all injury deaths). Causes of mortality were drowning (n=10) and burns (n=2). The proportion of deaths due to drowning among PWE was significantly higher than that of the standard population (83% (10/12) vs. 7% (21/304), relative risk 12.6 (95% CI, 7.7–20.7, p<0.0001)). Mortality due to injury in PWE occurred at a younger age compared to people without epilepsy (mean difference 20.7 years (95% CI 6.7, 34.3), p<0.004). Conclusions There is a high proportion of accidental deaths due to drowning in PWE in Bangladesh compared to the standard population. Given the risk of seasonal flooding and low level of formal education, programs targeting water safety for PWE at all ages should be emphasized, appropriate for level of ability. PMID:22341966

To determine the rate and risk of suicide and accidental fatal drug overdose (ie, overdose deemed not to have been suicide) in individuals who had been medically ascertained as having been sexually abused during childhood. A historical cohort linkage study of suicide and accidental drug-induced death among victims of child sexual abuse (CSA). Forensic medical records of 2759 victims of CSA who were assessed between 1964 and 1995 were obtained from the Victorian Institute of Forensic Medicine and linked with coronial data representing a follow-up period of up to 44 years. Rates of suicide and accidental fatal drug overdose recorded in coronial databases between 1991 and 2008, and rates of psychiatric disorders and substance use recorded in public mental health databases. Twenty-one cases of fatal self-harm were recorded. Relative risks for suicide and accidental fatal overdose among CSA victims, compared with age-limited national data for the general population, were 18.09 (95% CI, 10.96-29.85; population-attributable risk, 0.37%), and 49.22 (95% CI, 36.11-67.09; population-attributable risk, 0.01%) respectively. Relative risks were higher for female victims. Similar to the general population, CSA victims who died as a result of self-harm were predominantly aged in their 30s at time of death. Most had contact with the public mental health system and half were recorded as being diagnosed with an anxiety disorder. Our data highlight that CSA victims are at increased risk of suicide and accidental fatal drug overdose. CSA is a risk factor that mediates suicide and fatal overdose.

This is a case report concerning a veterinarian who spilled detomidine and butorphanol on dermatitic hands while sedating a horse. This resulted in acute poisoning from which the patient spontaneously recovered with supportive management. Veterinarians often suffer from occupational dermatitis and handle strong sedatives with no gloves while working around unpredictable animals. Thus, this group is at risk of accidental self-poisoning from this method.

Investigating injuries in terms of occurrences and patient and hospital stay characteristics. 17370 stays, with at least one E code, were investigated based on data from 13 Belgian hospitals. Pearson's chi-square and Kruskal-Wallis tests were used to assess the variations between distributions of the investigated factors according to the injury's types. Major injuries were accidental falls, transport injuries, and self-inflicted injuries. There were more men in the transport injuries group and the accidental falls group was older. For the transport injuries, there were more arrivals with the support of a mobile intensive care unit and/or a paramedic intervention team and a general practitioner was more implicated for the accidental falls. In three-quarters of cases, it was a primary diagnostic related to injury and poisoning which was made. The median length of stay was nearly equal to one week and for accidental falls, this value is three times higher. The median cost, from the social security point of view, for all injuries was equal to € 1377 and there was a higher median cost within the falls group. This study based on hospitals data provides important information both on factors associated with and on hospital costs generated by injuries.

Acute exogenous lipoid pneumonia is an uncommon condition caused by aspiration of oil-based substances, occurring mainly in children. Here, we report the case of an 83-year-old patient with Alzheimer's disease who presented with coughing and hypoxia. The diagnosis of acute exogenous lipoid pneumonia caused by accidental kerosene ingestion was made on the basis of the patient's clinical history, and typical radiological and cytological findings. The patient's cognitive impairment and an unsafe environment, in which the patient's 91-year-old husband stored kerosene in an old shochu bottle, were responsible for the accidental ingestion. Acute exogenous lipoid pneumonia should be considered in the differential diagnosis for acute respiratory disorders in the rapidly aging population. © 2013 Japan Geriatrics Society.

Non-accidental properties, metric invariance, and encoding by neurons in a model of ventral stream visual object recognition, VisNet.

PubMed

Rolls, Edmund T; Mills, W Patrick C

2018-05-01

When objects transform into different views, some properties are maintained, such as whether the edges are convex or concave, and these non-accidental properties are likely to be important in view-invariant object recognition. The metric properties, such as the degree of curvature, may change with different views, and are less likely to be useful in object recognition. It is shown that in a model of invariant visual object recognition in the ventral visual stream, VisNet, non-accidental properties are encoded much more than metric properties by neurons. Moreover, it is shown how with the temporal trace rule training in VisNet, non-accidental properties of objects become encoded by neurons, and how metric properties are treated invariantly. We also show how VisNet can generalize between different objects if they have the same non-accidental property, because the metric properties are likely to overlap. VisNet is a 4-layer unsupervised model of visual object recognition trained by competitive learning that utilizes a temporal trace learning rule to implement the learning of invariance using views that occur close together in time. A second crucial property of this model of object recognition is, when neurons in the level corresponding to the inferior temporal visual cortex respond selectively to objects, whether neurons in the intermediate layers can respond to combinations of features that may be parts of two or more objects. In an investigation using the four sides of a square presented in every possible combination, it was shown that even though different layer 4 neurons are tuned to encode each feature or feature combination orthogonally, neurons in the intermediate layers can respond to features or feature combinations present is several objects. This property is an important part of the way in which high capacity can be achieved in the four-layer ventral visual cortical pathway. These findings concerning non-accidental properties and the use of neurons in intermediate layers of the hierarchy help to emphasise fundamental underlying principles of the computations that may be implemented in the ventral cortical visual stream used in object recognition.

2015-08-15

Substantial epidemiologic literature has demonstrated the effects of air pollution and temperature on mortality. However, there is inconsistent evidence regarding the temperature modification effect on acute mortality due to air pollution. Herein, we investigated the effects of temperature on the relationship between air pollution and mortality due to non-accidental, cardiovascular, and respiratory death in seven cities in South Korea. We applied stratified time-series models to the data sets in order to examine whether the effects of particulate matter <10 μm (PM10) on mortality were modified by temperature. The effect of PM10 on daily mortality was first quantified within different ranges of temperatures at each location using a time-series model, and then the estimates were pooled through a random-effects meta-analysis using the maximum likelihood method. From all the data sets, 828,787 non-accidental deaths were registered from 2000-2009. The highest overall risk between PM10 and non-accidental or cardiovascular mortality was observed on extremely hot days (daily mean temperature: >99th percentile) in individuals aged <65 years. In those aged ≥65 years, the highest overall risk between PM10 and non-accidental or cardiovascular mortality was observed on very hot days and not on extremely hot days (daily mean temperature: 95-99th percentile). There were strong harmful effects from PM10 on non-accidental mortality with the highest temperature range (>99th percentile) in men, with a very high temperature range (95-99th percentile) in women. Our findings showed that temperature can affect the relationship between the PM10 levels and cause-specific mortality. Moreover, the differences were apparent after considering the age and sex groups. Copyright © 2015 Elsevier B.V. All rights reserved.

Background Conflicting evidence exists on whether cholinesterase inhibitors and memantine increase the risk of falls, syncope, and related events, defined as fracture and accidental injury. Objectives To evaluate the effect of cholinesterase inhibitors and memantine on the risk of falls, syncope, and related events Design, Setting, Participants, and Intervention Meta-analysis of 54 placebo-controlled randomized trials and extension studies of cholinesterase inhibitors and memantine that reported falls, syncope, and related events in cognitively impaired older adults. Trials were identified from MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (no language restriction, through July 2009), and manual search. Measurements Falls, syncope, fracture, and accidental injury Results Compared to placebo, cholinesterase inhibitor use was associated with an increased risk of syncope (odds ratio [95% confidence interval]: 1.53 [1.02-2.30]), but not with other events (falls: 0.88 [0.74-1.04]; fracture: 1.39 [0.75-2.56]; accidental injury: 1.13 [0.87-1.45]). Memantine use was associated with fewer fractures (0.21 [0.05-0.85]), but not with other events (fall: 0.92 [0.72-1.18]; syncope: 1.04 [0.35-3.04]; accidental injury: 0.80 [0.56-1.12]). There was no differential effect by type and severity of cognitive impairment, residential status, nor length of follow-up. However, due to underreporting and small number of events, a potential benefit or risk cannot be excluded. Conclusion Cholinesterase inhibitors may increase the risk of syncope, with no effects on falls, fracture, and accidental injury in cognitively impaired older adults. Memantine may have a favorable effect on fracture, with no effects on other events. More research is needed to confirm the reduction in fractures observed for memantine. PMID:21649634

Multifractal properties of solar filaments and sunspots numbers

We analyze multifractal properties of low (LLSFNs; < 50 °), high (HLSFNs; ⩾ 50 °), full-disk (FDSFNs; 0 ° ˜ 90 °) solar filament numbers (SFNs) and international sunspot numbers (ISNs) by estimating characteristic parameters (α0, Δα , spectrum skewness) of f (α) singularity spectrum. We find that the SFNs and ISNs have multifractal nature. The obtained α0 and Δα indicate that long-term behaviour of the solar filaments is more complex than that of the sunspots and the high-latitude filaments is the most complex in long-term behaviour. The spectrum skewnesses manifest that the ISNs display well symmetrical distribution in singularity strengths, whereas the SFNs are dominated by low singularity strengths, which means that the long-term behaviour of sunspots has homogenous structures and the filaments display averagely small fluctuations in amplitude. To detect the origin of their multifractality, we decompose the raw data of ISNs and SFNs: smoothed data represent ˜11-year cyclic activities and detrended data represent accidental activities. We also calculate their f (α) spectra, respectively. We find that the ˜11-year cyclic activities of filaments and sunspots tend to be a monofractal and display a bit predominance of low singularity strengths. Their accidental activities have the most complex behaviour than the raw and smoothed data. The accidental activities are dominated by high singularity strengths showing averagely large fluctuations in amplitude. Furthermore, multifractal properties from α0 and Δα of the accidental activities have the same features as that of raw data. We think that the ˜11-year periodic activity determines global fluctuations, while the accidental activities rule local complexity.

We investigated the association between particulate matter less than 10 µm in aerodynamic diameter (PM₁₀) exposure and non-accidental mortality in Asian populations by meta-analysis, using both time-series and case-crossover analysis. Among the 819 published studies searched from PubMed and EMBASE using key words related to PM₁₀ exposure and non-accidental mortality in Asian countries, 8 time-series and 4 case-crossover studies were selected for meta-analysis after exclusion by selection criteria. We obtained the relative risk (RR) and 95% confidence intervals (CI) of non-accidental mortality per 10 µg/m³ increase of daily PM₁₀ from each study. We used Q statistics to test the heterogeneity of the results among the different studies and evaluated for publication bias using Begg funnel plot and Egger test. Testing for heterogeneity showed significance (p<0.001); thus, we applied a random-effects model. RR (95% CI) per 10 µg/m³ increase of daily PM₁₀ for both the time-series and case-crossover studies combined, time-series studies relative risk only, and case-crossover studies only, were 1.0047 (1.0033 to 1.0062), 1.0057 (1.0029 to 1.0086), and 1.0027 (1.0010 to 1.0043), respectively. The non-significant Egger test suggested that this analysis was not likely to have a publication bias. We found a significant positive association between PM₁₀ exposure and non-accidental mortality among Asian populations. Continued investigations are encouraged to contribute to the health impact assessment and public health management of air pollution in Asian countries.

The Impacts of Air Temperature on Accidental Casualties in Beijing, China.

2016-11-02

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.

Some critical methodological issues in secondary analysis of world health organization data on elderly suicide rates.

PubMed

Shah, Ajit

2009-07-01

Suicides may be misclassified as accidental deaths in countries with strict legal definitions of suicide, with cultural and religious factors leading to poor registration of suicide and stigma attached to suicide. The concordance between four different definitions of suicides was evaluated by examining the relationship between pure suicide and accidental death rates, gender differences, age-associated trends and potential distil risk and protective factors by conducting secondary analysis of the latest World Health Organisation data on elderly death rates. The four definitions of suicide were: (i) one-year pure suicides rates; one-year combined suicide rates (pure suicide rates combined with accidental death rates); (iii) five-year average pure suicide rates; and (iv) five-year average combined suicides rates (pure suicides rates combined with accidental death rates). The predicted negative correlation between pure suicide and accidental death rates was not observed. Gender differences were similar for all four definitions of suicide. There was a highly significant concordance for the findings of age-associated trends between one-year pure and combined suicide rates, one-year and five-year average pure suicide rates, and five-year average pure and combined suicide rates. There was poor concordance between pure and combined suicide rates for both one-year and five-year average data for the 14 potential distil risk and protective factors, but this concordance between one-year and five-year average pure suicide rates was highly significant. The use of one-year pure suicide rates in cross-national ecological studies examining gender differences, age-associated trends and potential distil risk and protective factors is likely to be practical, pragmatic and resource-efficient.

A unique case of accidental hanging due to compression of the neck of an adult by the branches of a coffee tree is reported. The decedent was a 42-year-old male who was found dead in a semi prone position on a slope. His neck was lodged in a wedge formed by two branches of a coffee tree, with his legs angled downwards on the slope. Autopsy revealed two friction abrasions located horizontally on either side of the front of the neck, just above the larynx. The findings were compatible with compression of the neck by the branches of the tree, with the body weight of the decedent contributing to compression. Subsequent complete autopsy examination confirmed the cause of death as hanging. Following an inquest the death was ruled to be accidental.

2018-01-01

Accidental cut-throat injuries are extremely rare and usually involve a sharp-edged weapon. In this paper, two cases of a cut-throat wound to two auto-rickshaw drivers are presented where the broken windshield of the auto-rickshaws was responsible for the wounds. In both the cases, fatal incised wounds were present over the neck, cutting the soft tissue along with the major vessels. The death occurred due to exsanguination caused by neck-vessel injury in one case and trachea along with neck-vessel injury in the second case. Although the wounds on the neck initially suggested homicide, they were found to have occurred accidentally as a result of a road traffic accident involving a head-on collision of auto rickshaws. The injuries were inflicted by the shattered glass of the windshield.

Estimation of the age of bruising.

PubMed Central

Stephenson, T; Bialas, Y

1996-01-01

Paediatricians are often requested to give an opinion on the age of a non-accidental bruise. In forensic textbooks, the colour changes which a bruise undergoes with time are not based on research in children. The purpose of this study was to document the sequence of colour changes in photographs taken following accidental bruising in children. Fifty accidental bruises of known age in 23 children were photographed by a medical photographer using the same equipment throughout. The photographs were reviewed by a single observer, blind to the true age of the injury, who described the colours present in the bruise. Red colouration was seen in 15 out of 37 bruises which were less than one week old. Yellow colouration was seen in 10 out of 42 bruises over one day old. Aging of bruises from photographs was much less precise than textbooks imply. PMID:8660049

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

Background Occupational exposure to manufactured nanomaterials (MNMs) and its potential health impacts are of scientific and practical interest, as previous epidemiological studies associate exposure to nanoparticles with health effects, including increased morbidity of the respiratory and the circulatory system. Objectives To estimate the occupational exposure and effective internal doses in a real production facility of TiO2 MNMs during hypothetical scenarios of accidental release. Methods Commercial software for geometry and mesh generation, as well as fluid flow and particle dispersion calculation, were used to estimate occupational exposure to MNMs. The results were introduced to in-house software to calculate internal doses in the human respiratory tract by inhalation. Results Depending on the accidental scenario, different areas of the production facility were affected by the released MNMs, with a higher dose exposure among individuals closer to the particles source. Conclusions Granted that the study of the accidental release of particles can only be performed by chance, this numerical approach provides valuable information regarding occupational exposure and contributes to better protection of personnel. The methodology can be used to identify occupational settings where the exposure to MNMs would be high during accidents, providing insight to health and safety officials. PMID:27670588

Psychological variables potentially implicated in opioid-related mortality as observed in clinical practice.

2011-06-01

Opioid-related deaths in the United States have become a public health problem, with accidental and unintended overdoses being especially troubling. Screening for psychological risk factors is an important first step in safeguarding against nonadherence practices and identifying patients who may be vulnerable to the risks associated with opioid therapy. Validated screening instruments can aid in this attempt as a complementary tool to clinicians' assessments. A structured screening is imperative as part of an assessment, as clinician judgment is not the most reliable method of identifying nonadherence. As a complement to formal screening, we present for discussion and possible future study certain psychological variables observed during years of clinical practice that may be linked to medication nonadherence and accidental overdose. These variables include catastrophizing, fear, impulsivity, attention deficit disorders, existential distress, and certain personality disorders. In our experience, chronic pain patients with dual diagnoses may become "chemical copers" as a way of coping with their negative emotion. For these patients, times of stress could lead to accidental overdose. Behavioral, cognitive-behavioral (acceptance and commitment, dialectical behavior), existential (meaning-centered, dignity), and psychotropic therapies have been effective in treating these high-risk comorbidities, while managing expectations of pain relief appears key to preventing accidental overdose.

To evaluate the incidence of unexplained falls in elderly patients affected by fall-related fractures admitted to orthopaedic wards, we recruited 246 consecutive patients older than 65 (mean age 82 ± 7 years, range 65-101). Falls were defined "accidental" (fall explained by a definite accidental cause), "medical" (fall caused directly by a specific medical disease), "dementia-related" (fall in patients affected by moderate-severe dementia), and "unexplained" (nonaccidental falls, not related to a clear medical or drug-induced cause or with no apparent cause). According to the anamnestic features of the event, older patients had a lower tendency to remember the fall. Patients with accidental fall remember more often the event. Unexplained falls were frequent in both groups of age. Accidental falls were more frequent in younger patients, while dementia-related falls were more common in the older ones. Patients with unexplained falls showed a higher number of depressive symptoms. In a multivariate analysis a higher GDS and syncopal spells were independent predictors of unexplained falls. In conclusion, more than one third of all falls in patients hospitalized in orthopaedic wards were unexplained, particularly in patients with depressive symptoms and syncopal spells. The identification of fall causes must be evaluated in older patients with a fall-related injury.

Knowledge and lessons from past accidental exposures in radiotherapy are very helpful in finding safety provisions to prevent recurrence. Disseminating lessons is necessary but not sufficient. There may be additional latent risks for other accidental exposures, which have not been reported or have not occurred, but are possible and may occur in the future if not identified, analyzed, and prevented by safety provisions. Proactive methods are available for anticipating and quantifying risk from potential event sequences. In this work, proactive methods, successfully used in industry, have been adapted and used in radiotherapy. Risk matrix is a tool that can be used in individual hospitals to classify event sequences in levels of risk. As with any anticipative method, the risk matrix involves a systematic search for potential risks; that is, any situation that can cause an accidental exposure. The method contributes new insights: The application of the risk matrix approach has identified that another group of less catastrophic but still severe single-patient events may have a higher probability, resulting in higher risk. The use of the risk matrix approach for safety assessment in individual hospitals would provide an opportunity for self-evaluation and managing the safety measures that are most suitable to the hospital's own conditions.

Accidental events concerning process industries can affect not only the staff working in, but also the environment and people living next to the factory. For this reason a regulation is imposed by the European Community to prevent accidents that could represent a risk for the population and the environment. In particular, Directive 96/82/CE, the so-called 'Seveso II directive', requests a risk analysis involving also the hazardous materials generated in accidental events. Therefore, it is necessary to develop simple and economic procedure to foresee the hazardous materials that can be produced in the case of major accidents, among which the accidental heating of a chemical due to a fire or a runaway reaction is one of the most frequent. The procedure proposed in this work is based on evolved gas analysis methodology that consists in coupling two instruments: a thermogravimetric analyzer or a flash pyrolyzer, that are employed to simulate accident conditions, and a FTIR spectrometer that can be used to detect the evolved gas composition. More than 40 materials have been examined in various accident scenarios and the obtained data have been statistically analyzed in order to identify meaningful correlations between the presence of a chemical group in the molecule of a chemical and the presence of a given hazardous species in the fume produced.

Retrospective evaluation of a series of patients presenting with genitourinary foreign objects. From 1997 to 2007, 11 men and 2 women were treated for a variety of foreign objects in the genitourinary tract. Medical records were reviewed for presentation, diagnosis, mental status, drug dependency, treatment, and follow-up. 13 patients were seen for removal of the foreign objects or for treatment of the sequela. These objects were intentionally self-inflicted, accidentally introduced or iatrogenic in nature. Intentional objects included: safety pins, screwdriver, marbles, pen cap, pencils, straw, cocaine, stiff metal wire and part of a pizza mixer. Accidental objects included: magnets, female catheter, urinary incontinence devices and part of a Foley catheter. The iatrogenic object was a reservoir from an inflatable penile implant. Smaller noninjurious objects were retrieved cystoscopically or at the bedside; larger objects or objects associated with trauma to the urethra needed open and reconstructive operations. Generally thought to be self-inflicted for personal gratification, the source of genitourinary objects can also be accidental or iatrogenic. The most traumatic injuries are purposely self-inflicted and found in patients who remove the objects themselves. These patients are at higher risk of permanent urethral damage needing complex surgical treatment and follow-up. Copyright (c) 2010 S. Karger AG, Basel.

To evaluate the occupational safety climate in different types of enterprises and its relationship with occupational accidental injury. A cross-sectional survey based on self-report questionnaires was performed among 3311 front-line workers from 54 medium and small-sized manufacturing enterprises of different types in Zhongshan, China to investigate the socio-demographic characteristics, safety climate experience in workplace, and incidence of occupational accidental injury in the past year. Analysis of the data revealed that employees in different types of companies perceived different levels of safety climate, according to the scores on four subscales; the European and American enterprises had significantly better safety climate than the Hong Kong and Chinese private enterprises (P < 0.01). The self-reported rates of occupational injury were 3.38%, 4.76%, and 6.72%, respectively, for European and American, Hong Kong, and Chinese private enterprises (χ(2) = 6.78, P < 0.05). After control of such factors as age, sex, income, education level, and marriage, the logistic regression analysis showed that the risk of occupational accidental injury in the European and American enterprises was significantly lower than that in the Chinese private enterprises (OR = 0.57, 95%CI = 0.35-0.91). The type of enterprise influences the occupational safety climate and incidence of occupational injury among workers.

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

PubMed

Riggs, Jack E; Hobbs, Gerald R

2011-07-01

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.

A 40-year-old mentally retarded woman died of accidental strangulation in a nursing home. She was found in a kneeling position with her hands on her knees and the collar of her clothing compressing the front and sides of the neck. Before the accident, a nurse had dressed the patient in one-piece overall-style pyjamas put on back to front so that she could not remove the garment herself. The post-mortem findings and reconstruction of the scene of death suggested that the patient had been strangled by the collar of her backward-facing clothing while in a kneeling position. Because patients with psychiatric illnesses may have a limited ability to recognize or communicate symptoms of physical danger, they must be closely monitored by knowledgeable medical and nursing staff. This case highlights the importance of preventing the accidental deaths of mentally retarded patients in nursing homes.

In girls who present with vaginal trauma, sexual abuse is often the primary diagnosis. The differential diagnosis must include patterns and the mechanism of injury that differentiate accidental injuries from inflicted trauma. A 7-year-old prepubertal girl presented to the emergency department with genital bleeding after a serious accidental impaling injury from inline skating. After rapid abduction of the legs and a fall onto the blade of an inline skate this child incurred an impaling genital injury consistent with an accidental mechanism. The dramatic genital injuries when repaired healed with almost imperceptible residual evidence of previous trauma. To our knowledge, this case report represents the first in the medical literature of an impaling vaginal trauma from an inline skate and describes its clinical and surgical management.

Accidental ingestion of medium-to-large instruments is relatively uncommon during dental treatment but can be potentially dangerous. A case of BiTine ring ingestion is presented with a note on inefficient ring separation forceps. A 28-year-old male patient accidentally ingested the BiTine ring (2 cm diameter, 0.5 cm outward projections) while it was being applied to a distoproximal cavity in tooth # 19. The ring placement forceps were excessively flexible; bending of the beaks towards the ring combined with a poor no-slippage mechanism led to sudden disengagement of the ring and accelerated movement towards the pharynx. We followed the patient with bulk forming agents and radiographs. Fortunately the ring passed out without any complications. Checking equipment and methods is as important as taking precautions against any preventable medical emergency. It is the responsibility of the clinician to check, verify and then use any instrument/equipment.

Accidental versus operational oil spills from shipping in the Baltic Sea: risk governance and management strategies.

PubMed

Hassler, Björn

2011-03-01

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.

1998-06-01

This study investigates the understanding of others' intentions in 2- and 3-year-old children, chimpanzees (Pan troglodytes), and orangutans (Pongo pygmaeus). During training, subjects learned to use a discriminative cue to select a baited box. During testing, the experimenter placed a marker on top of the baited box to inform the subject of the reward's location. However, the experimenter also accidentally dropped the marker on top of an unbaited box, so that during any given trial the experimenter marked 2 boxes, 1 intentionally and 1 accidentally. All 3 species preferentially selected the box the experimenter had marked intentionally (especially during the initial trials), with 3-year-old children presenting the most robust results. These findings suggest that subjects understood something about the experimenter's intentions. The authors speculate that understanding of others' intentions may precede the understanding of others' beliefs both at the ontogenetic and phylogenetic levels.

Food allergy: practical approach on education and accidental exposure prevention.

2016-09-01

Food allergies are a growing problem and currently the primary treatment of food allergy is avoidance of culprit foods. However, given the lack of information and education and also the ubiquitous nature of allergens, accidental exposures to food allergens are not uncommon. The fear of potential fatal reactions and the need of a proper avoidance leads in most of the cases to the limitation of leisure and social activities. This review aims to be a practical approach on education and accidental exposure prevention regarding activities like shopping, eating out, and travelling. The recommendations are focused especially on proper reading of food labels and the management of the disease, namely in restaurants and airplanes, concerning cross-contact and communication with other stakeholders. The implementation of effective tools is essential to manage food allergy outside home, avoid serious allergic reactions and minimize the disease's impact on individuals' quality of life.

Lethal cases in mountain tourism and sports in the Republic of Kabardino-Balkaria were studied for 1978-1995. A total of 152 accidental deaths were analysed. Most of the victims were males under 30 years of age. The greatest number of the accidents took place on Monday, in July and August. Many amateur visitors from abroad were among the victims. The main cause of death in the mountains of Kabardino-Balkaria for the 18 years studied was multitrauma of the body (69.7%). Hypothermia and obturation asphyxia with snow and compression asphyxia due to snowbreak account for 11.8 and 13.2% deaths, respectively; lightning killed 4%. Combination of high mountain hypoxia with exacerbated chronic somatic disease or hypothermia caused death in 1% victims. The authors propose how to improve forensic-medical expert examination of accidental death and safety in the mountains.

We present an innovative architecture of a Rayleigh-based optical fibre sensor for the monitoring of water level and temperature inside storage nuclear fuel pools. This sensor, able to withstand the harsh constraints encountered under accidental conditions such as those pointed-out during the Fukushima-Daiichi event (temperature up to 100 °C and radiation dose level up to ~20 kGy), exploits the Optical Frequency Domain Reflectometry technique to remotely monitor a radiation resistant silica-based optical fibre i.e. its sensing probe. We validate the efficiency and the robustness of water level measurements, which are extrapolated from the temperature profile along the fibre length, in a dedicated test bench allowing the simulation of the environmental operating and accidental conditions. The conceived prototype ensures an easy, practical and no invasive integration into existing nuclear facilities. The obtained results represent a significant breakthrough and comfort the ability of the developed system to overcome both operating and accidental constraints providing the distributed profiles of the water level (0-to-5 m) and temperature (20-to-100 °C) with a resolution that in accidental condition is better than 3 cm and of ~0.5 °C respectively. These new sensors will be able, as safeguards, to contribute and reinforce the safety in existing and future nuclear power plants.

Infection with hepatitis viruses following blood exposure accidents, such as needle stick injuries, is a serious issue for medical staff. In particular, although accidental exposure to hepatitis C virus (HCV) occurs frequently, postexposure prophylactic measures have not been established yet. In this study we investigate the efficacy of recombinant alpha-2b interferon (IFN) as a single, 10 MU intramuscular injection for preventing transmission. 264 incidents of accidental blood to HCV antibody-positive blood, occurring between 1993 and 2003 in the Social Insurance Chukyo Hospital, were surveyed. Accident reports, which described in detail the circumstances and the presence or absence of infectious disease in the blood, and accidental exposure to HCV antibody-positive blood was investigated. Pre-emptive IFN treatment was given in 115 out of 157 cases occurring between 1993 and 1998. One case developed acute HCV. Phylogenetic analysis provided evidence that the accident caused the infection and the patient was cured by immediate IFN therapy. Between 1999 and 2003, the exposed were in principle followed-up without IFN treatment; IFN treatment was only given when requested. As a result, IFN was given in 14 of 107 cases. During this period, no transmission was observed. Taken together, the benefits of pre-emptive IFN treatment were considered unremarkable and a follow-up without treatment, or immediate IFN therapy after confirmation of the onset, was recommended.

Nuclear magnetic resonance in low-symmetry superconductors

NASA Astrophysics Data System (ADS)

Cavanagh, D. C.; Powell, B. J.

2018-01-01

We consider the nuclear spin-lattice relaxation rate 1 /T1 in superconductors with accidental nodes, i.e., zeros of the order parameter that are not enforced by its symmetries. Such nodes in the superconducting gap are not constrained by symmetry to a particular position on the Fermi surface. We show, analytically and numerically, that a Hebel-Slichter-like peak occurs even in the absence of an isotropic component of the superconducting gap. For a gap with symmetry-required nodes the Fermi velocity at the node must point along the node. For accidental nodes this is not, in general, the case. This leads to additional terms in spectral function and hence the density of states. These terms lead to a logarithmic divergence in 1 /T1T at T →Tc- in models neglecting disorder and interactions [except for those leading to superconductivity; here T is temperature, Tc-=limδ→0(Tc-δ ) , and Tc is the critical temperature]. This contrasts with the usual Hebel-Slichter peak which arises from the coherence factors due to the isotropic component of the gap and leads to a divergence in 1 /T1T somewhat below Tc. The divergence in superconductors with accidental nodes is controlled by either disorder or additional electron-electron interactions. However, for reasonable parameters, neither of these effects removes the peak altogether. This provides a simple experimental method to distinguish between symmetry-required and accidental nodes.

In the case of accidental release of Uranium-238 ({sup 238}U) radionuclides in a nuclear facility or in the environment, internal contamination by either acute or chronic exposure has the potential to induce both radiological and chemical toxic effects. A study was conducted to estimate the {sup 238}U radionuclide concentration in the long beans using Induced Coupled Mass Plasma-Spectrometry (ICP-MS). {sup 238}U radionuclide is a naturally occurring radioactive material that can be found in soil and can be transferred to the long bean (Vigna unguiculata subsp. Sesquapedalis) directly or indirectly via water or air. Kidney and liver are the major sitesmore » of deposition of {sup 238}U radionuclide. The obtained dose exposed in the liver and kidney is used to assess the safety level for public intake of {sup 238}U radionuclide from the consumption of long beans. The concentration of {sup 238}U radionuclide measured in long bean samples was 0.0226 ± 0.0009 mg/kg. Total activity of {sup 238}U radionuclide was 0.0044 ± 0.0002 Bq/day with the daily intake of 0.3545 ± 0.0143 µg/day and the annual committed effective dose due to ingestion of {sup 238}U radionuclide in long beans was 0.2230 ± 0.0087 µSv/year. The committed equivalent dose of {sup 238}U radionuclide from the assessment in the liver and kidney are 0.4198 ± 0.0165 nSv and 10.9335 ± 0.4288 nSv. The risk of cancer of {sup 238}U radionuclide was determined to be (86.0466 ± 3.3748) × 10-9. Thus, the results concluded that {sup 238}U radionuclide in local long beans was in the permitted level and safe to consume without posing any significant radiological threat to population.« less

In present study, composition profiles and health risk of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in outdoor air and fly ash from domestic waste treatment center (DWTC) were studied. In addition, the composition profiles and health risk of PCDD/F in outdoor air from adjacent villages were researched and used to quantitatively analyze the difference between onsite workers and adjacent villagers. Moreover, the difference between old intake method and new inhalation dosimetry method in the process of assessing the health risk of PCDD/Fs in outdoor air was quantitatively compared and analyzed. The results of this study were summarized as follows. (1) The 95th percentile carcinogenic risk (CR) and non-carcinogenic risk (non-CR) for onsite workers and adjacent villagers were much lower than the threshold values of 10(-6) and 1.0, respectively, suggesting no potential health risk. (2) The 95th percentile CR for onsite workers was 1.27×10(-8) and was 64.8 times higher than that of adjacent villagers (1.99×10(-10)). (3) The 95th percentile non-CR for onsite workers and adjacent villagers were 1.37×10(-4) and 1.31×10(-7), respectively. (3) Accidental ingestion of fly ash was the largest contributor to CR and non-CR for onsite workers, contributing 62.98% and 64.04% to CR and non-CR, respectively. (4) The CR and non-CR of PCDD/Fs in outdoor air for onsite workers and adjacent villagers which calculated by old intake method was much higher than the results from new inhalation dosimetry method. The results quantitatively showed the levels and potential risks of PCDD/Fs posed by a DWTC site, which can be helpful to predict the influence from DWTC sites and promote the management of DWTC in China.

After the incidences of induction of aristolochic acid nephropathy after consumption of herbal weight loss preparations that accidentally contained aristolochic acids (AAs), several countries defined national restrictions on the presence of AAs in food, including plant food supplements (PFS) and herbal products. This study investigates whether the risks associated with exposure to AAs via PFS and herbal products are at present indeed negligible. Data reported in literature on AA levels in PFS and other herbal products and also obtained from a new series of PFS in the present study were used to calculate the estimated daily intakes (EDIs) and corresponding margins of exposure (MOEs). Available literature data revealed that 206 out of 573 samples were found to contain aristolochic acid I (AAI) and/or aristolochic acid II (AAII). The results obtained from recently collected PFS revealed that both AAI and AAII were detected in three out of 18 analysed PFS at levels up to 594.8 and 235.3 µg g -1 , respectively, being in line with the levels reported in literature. The EDIs resulting from intake of these PFS resulted in MOEs that were generally below 10,000, corroborating the priority for risk management. Although these results refer to PFS collected by targeted sampling strategies, the data reveal that AA-containing PFS are still freely available. When considering that the use of these samples may be limited to shorter periods of time, the EDIs might be lower, but MOE values would still be lower than 10,000 for more than 50% of the AA-containing PFS and herbal products. In conclusion, the presence of AAs in PFS and herbal products even several years after instalment of the legal restrictions still raises concern, especially for people who frequently use the respective PFS and herbal products.

[Decorporation agents for internal radioactive contamination].

PubMed

Ohmachi, Yasushi

2015-01-01

When radionuclides are accidentally ingested or inhaled, blood circulation or tissue/organ deposition of the radionuclides causes systemic or local radiation effects. In such cases, decorporation therapy is used to reduce the health risks due to their intake. Decorporation therapy includes reduction and/or inhibition of absorption from the gastrointestinal tract, isotopic dilution, and the use of diuretics, adsorbents, and chelating agents. For example, penicillamine is recommended as a chelating agent for copper contamination, and diethylene triamine pentaacetic acid is approved for the treatment of internal contamination with plutonium. During chelation therapy, the removal effect of the drugs should be monitored using a whole-body counter and/or bioassay. Some authorities, such as the National Council on Radiation Protection and Measurements and International Atomic Energy Agency, have reported recommended decorporation agents for each radionuclide. However, few drugs are approved by the US Food and Drug Administration, and many are off-label-use agents. Because many decontamination agents are drugs that have been available for a long time and have limited efficacy, the development of new, higher-efficacy drugs has been carried out mainly in the USA and France. In this article, in addition to an outline of decorporation agents for internal radioactive contamination, an outline of our research on decorporation agents for actinide (uranium and plutonium) contamination and for radio-cesium contamination is also presented.

Most burns happen in low- and middle-income countries. In India, deaths related to burns are more common in women than in men and occur against a complex background in which the cause - accidental or non-accidental, suicidal or homicidal - is often unclear. Our study aimed to understand the antecedents to burns and the problem of ascribing cause, the sequence of medicolegal events after a woman was admitted to hospital, and potential opportunities for improvement. We conducted semi-structured interviews with 33 women admitted to two major burns units, their families, and 26 key informant doctors, nurses, and police officers. We used framework analysis to examine the context in which burns occurred and the sequence of medicolegal action after admission to hospital. Interviewees described accidents, attempted suicide, and attempted homicide. Distinguishing between these was difficult because the underlying combination of poverty and cultural precedent was common to all and action was contingent on potentially conflicting narratives. Space constraint, problems with cooking equipment, and inflammable clothing increased the risk of accidental burns, but coexisted with household conflict, gender-based violence, and alcohol use. Most burns were initially ascribed to accidents. Clinicians adhered to medicolegal procedures, the police carried out their investigative requirements relatively rapidly, but both groups felt vulnerable in the face of the legal process. Women's understandable reticence to describe burns as non-accidental, the contested nature of statements, their perceived history of changeability, the limited quality and validity of forensic evidence, and the requirement for resilience on the part of clients underlay a general pessimism. The similarities between accident and intention cluster so tightly as to make them challenging to distinguish, especially given women's understandable reticence to describe burns as non-accidental. The contested status of forensic evidence and a reliance on testimony means that only a minority of cases lead to conviction. The emphasis should be on improving documentation, communication between service providers, and public understanding of the risks of burns.

To analyze the temperature modification effect on acute mortality due to particulate air pollution. Daily non-accidental mortality, cardiovascular mortality, and respiratory mortality data were obtained from Jiang'an District Center for Disease Control and Prevention. Daily meteorological data on mean temperature and relative humidity were collected from China Meteorological Data Sharing Service System. The daily concentration of particulate matter was collected from Wuhan Environmental Monitoring center. By using the stratified time-series models, we analyzed effects of particulate air pollution on mortality under different temperature zone from 2002 to 2010, meanwhile comparing the difference of age, gender and educational level, in Wuhan city of China. High temperature (daily average temperature > 33.4 ℃) obviously enhanced the effect of PM10 on mortality. With 10 μg/m(3) increase in PM10 concentrations, non-accidental, cardiovascular, and respiratory mortality increased 2.95% (95%CI: 1.68%-4.24%), 3.58% (95%CI: 1.72%-5.49%), and 5.07% (95%CI: 2.03%-9.51%) respectively. However, low temperature (daily average temperature <-0.21 ℃) enhanced PM10 effect on respiratory mortality with 3.31% (95% CI: 0.07%-6.64%) increase. At high temperature, PM10 had significantly stronger effect on non-accidental mortality of female aged over 65 and people with high educational level groups. With an increase of 10 μg/m(3), daily non-accidental mortality increased 4.27% (95% CI:2.45%-6.12%), 3.38% (95% CI:1.93%-4.86%) and 3.47% (95% CI:1.79%-5.18%), respectively. Whereas people with low educational level were more susceptible to low temperature. A 10 μg/m(3) increase in PM10 was associated with 2.11% (95% CI: 0.20%-4.04%) for non-accidental mortality. Temperature factor can modify the association between the PM10 level and cause-specific mortality. Moreover, the differences were apparent after considering the age, gender and education groups.

Introducción la retención laboral es un tema de suma importancia, porque se requiere de profesionales en el primer nivel de atención (PNA). El objetivo fue determinar si los accidentes laborales se asociaron al desánimo de los médicos para trabajar en el PNA de Lima, Perú. Métodos estudio transversal analítico de datos secundarios de una base de datos generada de una encuesta a médicos que realizaron su Servicio Rural y Urbano-Marginal en Salud (SERUMS). Se incluyó solo a los médicos que manifestaron al inicio del SERUMS que podían trabajar en el PNA de Lima. Se definió como cambio de intención de trabajo en el PNA a los que finalizando el SERUMS refirieron que ya no deseaban laborar en Lima. Esto se asoció según si tuvieron un accidente laboral y se ajustó por otras variables. Resultados de los 124 médicos el 63% fueron hombres (78). La mediana de edad fue de 26 años (rango intercuartílico: 25-27 años). Después de su SERUMS, el 12% (15) manifestó que cambió su interés y que deseaba trabajar en la capital. En el análisis multivariado, haber tenido un accidente laboral disminuyó la frecuencia del cambio de intención de trabajo en el PNA (RPa: 0.28, IC 95%: 0.14-0.54, p < 0,001), ajustado por ocho variables. Conclusiones en un estudio previo los accidentes laborales disminuyeron la frecuencia de trabajar en provincias, pero nuestro estudio dice lo contrario, posiblemente por la percepción de que un trabajo en la capital del país permite estar más cerca de los servicios para ser atendido en caso de cualquier emergencia.

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 vaccines to the areas of most difficult access. Copyright © 2014 The Authors.

This study encompassed the total number of homicides in Bosnia and Herzegovina (B&H) in the period from 1st January 1997 to 31st December 2006 and then analysed homicidal behaviour. The aim is to assess the differences between the people who committed violent and those who committed accidental homicide in Bosnia and Herzegovina. In a multicentric, retrospective study of comparing the groups with equal number of respondents we analysed the individuals who had committed violent (n=135) and accidental homicides (n=135). The homicides were tested by using sociodemographic and psychosocial items. Measurement instruments were: General data list, Eysenck Personality Questionnaire (EPQ), Hamilton Depression Rating Scale (HDRS), Emotions Profile Index (EPI). The descriptive and multivariable logistic analysis was done statistically. In the descriptive analysis the socio-demographically violent murderers were: male gender (chi 2=3.340, P=0.009), more workers than officials (chi 2=7.340, P=0.011), fathers were more often workers/farmers (chi 2=1.430, P=0.046), gambling (chi 2=13.100, P=0.001) and possible recidivism (chi 2=6.770, a P=0.001). The accidental murderers were family people (chi 2=4.100, P=0.041), with more frequent drug abuse (chi 2=3.190, P=0.012) and they would not repeat the delict. In the multivariate analysis the violent murderers were highly discriminated (P=0.001) from accidental ones by: war involvement r=0.1148, OR=2.971 (95%), CI=1.040-7.890; age, father's education, psychoticism (EPQ) r =-0.1085, OR=0.291 (95%), CI=0.110-0870, HDRS-total r=-0.1797, OR=0.830 (95%), CI=0.710-0.930, destructiveness r=0.1270, OR=1.560 (95%), (CI=1.197-2.032, and deprivation in the P. I. E. tests. By the violence of their acts murderers confirm micro-social model of transferring the violence, and transition and heredity confirm the ecological-developmental trans-generation model of violence. Accidental murderers commit homicide in anomy, with intoxications and prolonged psycho-traumatism.

Consequence analysis in LPG installation using an integrated computer package.

This paper presents the prototype of the computer code, Atlantide, developed to assess the consequences associated with accidental events that can occur in a LPG storage plant. The characteristic of Atlantide is to be simple enough but at the same time adequate to cope with consequence analysis as required by Italian legislation in fulfilling the Seveso Directive. The application of Atlantide is appropriate for LPG storage/transferring installations. The models and correlations implemented in the code are relevant to flashing liquid releases, heavy gas dispersion and other typical phenomena such as BLEVE/Fireball. The computer code allows, on the basis of the operating/design characteristics, the study of the relevant accidental events from the evaluation of the release rate (liquid, gaseous and two-phase) in the unit involved, to the analysis of the subsequent evaporation and dispersion, up to the assessment of the final phenomena of fire and explosion. This is done taking as reference simplified Event Trees which describe the evolution of accidental scenarios, taking into account the most likely meteorological conditions, the different release situations and other features typical of a LPG installation. The limited input data required and the automatic linking between the single models, that are activated in a defined sequence, depending on the accidental event selected, minimize both the time required for the risk analysis and the possibility of errors. Models and equations implemented in Atlantide have been selected from public literature or in-house developed software and tailored with the aim to be easy to use and fast to run but, nevertheless, able to provide realistic simulation of the accidental event as well as reliable results, in terms of physical effects and hazardous areas. The results have been compared with those of other internationally recognized codes and with the criteria adopted by Italian authorities to verify the Safety Reports for LPG installations. A brief of the theoretical basis of each model implemented in Atlantide and an example of application are included in the paper.

Kerosene belongs to the hydrocarbon group of compounds, used as a fuel for lamps, as well as heating and cooking in developing countries. Accidental kerosene poisoning and intoxication usually occur by inhalation or by occupational percutaneous absorption. Adults usually ingest kerosene for the purpose of self-harm, and children may ingest accidentally. Suicidal attempt using intravenous kerosene is an extra ordinary and very rare occurrence. A very few data are available regarding effects of intravenous administration of kerosene and its management.

Because the margin of safety is low between the analgesic and toxic dose, intoxication is not rare when Aconite is used in herbal medicine. We present a case in which a 39-year-old male was accidentally intoxicated with Aconite. Even though no antidote or adequate therapy is available he was successfully resuscitated.

Objective: To identify cause-specific death and attributed burden of low bone mineral density in China among population aged ≥40 years old , 1990 and 2013. Methods: By using data from Global Burden of Disease(GBD)2013, this study analyzed death caused by low mineral density, and disability-adjusted life years(DALY)among population aged 40 and above in China(not including Taiwan, China). This study also analyzed DALY by composition of injury which due to low bone mineral density. It also analyzed changes in DALY by provinces in China, 1990 and 2013. An average world population age-structure for the period 2000- 2025 was adopted to calculate the age standardized rates. Results: In 2013, there were 38.1 thousands male and 30.7 thousands female who aged 40 and above dead due to low bone mineral density in China. The burden of injury caused by low bone mineral density was more sever in male than female, which accounted for 1.525 million DALY in male and 0.873 million DALY in female. In 1990, low bone mineral density attributed transportation and accidental injury caused 0.794 million and 0.567 million DALY losses, respectively. In 2013, low bone mineral density attributed transportation and accidental injury caused 1.421 million and 0.951 million DALY losses, respectively. Compared to 1990, DALY losses caused by transportation and accidental injury, increased by 79.1% and 67.6%, respectively. In 1990, DALY rate losses due to low bone mineral density attributed transportation and accidental injury were 68.1 per 100 000 and 48.7 per 100 000, respectively. In 2013, DALY rate losses due to low bone mineral density attributed transportation and accidental injury were 102.0 per 100 000 and 68.2 per 100 000, respectively. Compared to 1990, DALY rates which caused by transportation and accidental injury, increased by 49.8% and 40.2%, respectively. According to the ranking of standardized DALY rate in 2013 by provinces, the top 3 provinces, which standardized DALYs attributed to low bone mineral density lost the most, were Zhejiang Province(2.6 per 100 000), Jiangsu Province(2.4 per 100 000), and Fujian Province(2.2 per 100 000). Compared to 1990, the standardized rate of DALY decreased in 27 provinces, while the DALY rate increased in only 6 provinces which included Ningxia Hui Autonomous Region, Qinghai Province, Hebei Province, Guangxi Zhuang Autonomous Region, and Henan Province and Xinjiang Uygur Autonomous Region. Conclusion: This study found that the burden of health losses attributed to it was higher in men than in women. Compared to 1990, DALY rates decreased in most of the provinces, however, the rates of losses of DALY which caused by transportation and accidental injury were still increasing.

[Cardiac arrest due to accidental hypothermia and prolonged cardiopulmonary resuscitation].

PubMed

Kot, P; Botella, J

2010-11-01

In cardiac arrest produced by accidental hypothermia, cardiopulmonary resuscitation must be prolonged until normal body temperature is achieved. There are different rewarming methods. In theory, the more invasive ones are elective in patients with cardiac arrest because of their higher rewarming speed. However, it has not been proven that these methods are better than the non-invasive ones. We present a case report of a patient with cardiac arrest due to accidental hypothermia who was treated without interruption for three hours with heart massage. This is the longest successful cardiopulmonary resuscitation known up-to-date in Spain. In order to rewarm the body, a combination of non-invasive methods was used: active external rewarming with convective warm air, gastric and bladder lavage with warm saline solution and intravenous warm saline infusion. This case shows that it is possible to treat hypothermic cardiac arrest successfully through these rewarming methods, which are both easy to apply and feasible in any hospital.

Veratrum album (white or false hellebore) is a poisonous plant containing steroidal alkaloids that cause nausea, vomiting, headache, visual disturbances, paresthesia, dizziness, bradycardia, atrioventricular block, hypotension, and syncope. It is regularly mistaken for Gentiana lutea (yellow gentian). We report accidental poisoning with V. album mistaken for Allium ursinum (wild garlic), a wild plant used in soups and salads in Central Europe. Four adults (24-45 years) accidentally ingested V. album mistaken for A. ursinum in self-prepared salads and soups. Within 15-30 min of ingestion they developed nausea, vomiting, and abdominal pain. At the same time dizziness, tingling, dimmed and jumping vision, transient blindness, and confusion appeared. On arrival at the ED, all patients had sinus bradycardia and hypotension. Following treatment the patients were discharged well 24-48 h after ingestion. In patients presenting with gastrointestinal, neurological, and cardiovascular symptoms a history of wild plant ingestion suggests possible poisoning with V. album mistaken for wild garlic.

Compressed air is being used extensively as a source of energy at industries and in daily life. A variety of fatal injuries are caused by improper and ignorant use of compressed air equipments. Many types of injuries due to compressed air are reported in the literature such as colorectal injury, orbital injury, surgical emphysema, and so on. Most of these injuries are accidental in nature. It is documented that 40 pounds per square inch pressure causes fatal injuries to the ear, eyes, lungs, stomach, and intestine. Openings of body are vulnerable to injuries by compressed air. Death due to compressed air injuries is rarely reported. Many cases are treated successfully by conservative or surgical management. Extensive survey of literature revealed no reports of fatal injury to the upper respiratory tract and lungs caused by compressed air. Here, we are reporting a fatal event of accidental death after insertion of compressed air pipe into the mouth. The postmortem findings are corroborated with the history and discussed in detail.

Oil

Rocke, T.E.

1999-01-01

Each year, an average of 14 million gallons of oil from more than 10,000 accidental spills flow into fresh and saltwater environments in and around the United States. Most accidental oil spills occur when oil is transported by tankers or barges, but oil is also spilled during highway, rail, and pipeline transport, and by nontransportation-related facilities, such as refinery, bulk storage, and marine and land facilities (Fig. 42.1). Accidental releases, however, account for only a small percentage of all oil entering the environment; in heavily used urban estuaries, the total petroleum hydrocarbon contributions due to transportation activities may be 10 percent or less. Most oil is introduced to the environment by intentional discharges from normal transport and refining operations, industrial and municipal discharges, used lubricant and other waste oil disposal, urban runoff, river runoff, atmospheric deposition, and natural seeps. Oil-laden wastewater is often released into settling ponds and wetlands (Fig. 42.2). Discharges of oil field brines are a major source of the petroleum crude oil that enters estuaries in Texas.

Accidental degeneracy in k-space, geometrical phase, and the perturbation of π by spin-orbit interactions

NASA Astrophysics Data System (ADS)

Allen, Philip B.; Pickett, Warren E.

2018-06-01

Since closed lines of accidental electronic degeneracies were demonstrated to be possible, even frequent, by Herring in 1937, no further developments arose for eight decades. The earliest report of such a nodal loop in a real material - aluminum - is recounted and elaborated on. Nodal loop semimetals have become a focus of recent activity, with emphasis on other issues. Band degeneracies are, after all, the origin of topological phases in crystalline materials. Spin-orbit interaction lifts accidental band degeneracies, with the resulting spectrum being provided here. The geometric phase γ(C) = ± π for circuits C surrounding a line of such degeneracy cannot survive completely unchanged. The change depends on how the spin is fixed during adiabatic evolution. For spin fixed along the internal spin-orbit field, γ(C) decreases to zero as the circuit collapses around the line of lifted degeneracy. For spin fixed along a perpendicular axis, the conical intersection persists and γ(C) = ± π is unchanged.

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.

Few studies have been published to demonstrate tolerability and efficacy of almotriptan in adolescents and children with migraine, particularly in the first years of life, though preliminary results are favorable. We report the case of an 18-month-old infant with elevation of serum levels of creatin-kinase after the accidental ingestion of almotriptan. A previously healthy 18-month-old girl (weight: 13 kg) was admitted to our Department four hours after the accidental ingestion of 6.25 mg of almotriptan (0.48 mg/kg), without any specific symptom. The performed investigations showed high serum levels of creatin-kinase (CK) (527 IU/L; normal values: 24-170 IU/L). Transaminase, creatinine, aldolase, myoglobin and troponin T serum levels were normal. The electrocardiogram proved negative. Initial management consisted of parenteral rehydration with saline solution. CK levels lowered significantly at 12 hours (455 IU/L) and at 65 hours (188 IU/L) after the ingestion. No symptoms were observed before discharge and on follow-up.

Aluminum phosphide is one of the commonest poisons encountered in agricultural areas, and manner of death in the victims is often suicidal and rarely homicidal or accidental. This paper presents an unusual case, where two humans (owner and housemaid) and eight dogs were found dead in the morning hours inside a room of a house, used as shelter for stray dogs. There was allegation by the son of the owner that his father had been killed. Crime scene visit by forensic pathologists helped to collect vital evidence. Autopsies of both the human victims and the dogs were conducted. Toxicological analysis of viscera, vomitus, leftover food, and chemical container at the crime scene tested positive for aluminum phosphide. The cause of death in both humans and dogs was aluminum phosphide poisoning. Investigation by police and the forensic approach to the case helped in ascertaining the manner of death, which was accidental. © 2015 American Academy of Forensic Sciences.

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

DOEpatents

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.

Lights out: Impact of the August 2003 power outage on mortality in New York, NY

Background Little is known about how power outages affect health. We investigated mortality effects of the largest US blackout to date, August 14–15, 2003 in New York, NY. Methods We estimated mortality risk in New York, NY, using a generalized linear model with data from 1987–2005. We incorporated possible confounders, including weather and long-term and seasonal mortality trends. Results During the blackout, mortality increased for accidental deaths (122% [95% confidence interval = 28%–287%]) and non-accidental (i.e., disease-related) deaths (25% [12%–41%]), resulting in approximately 90 excess deaths. Increased mortality was not from deaths being advanced by a few days; rather, mortality risk remained slightly elevated through August 2003. Discussion To our knowledge, this is the first analysis of power outages and non-accidental mortality. Understanding the impact of power outages on human health is relevant, given that increased energy demand and climate change are likely to put added strain on power grids. PMID:22252408

A probabilistic model for accidental cargo oil outflow from product tankers in a ship-ship collision.

Goerlandt, Floris; Montewka, Jakub

2014-02-15

In risk assessment of maritime transportation, estimation of accidental oil outflow from tankers is important for assessing environmental impacts. However, there typically is limited data concerning the specific structural design and tank arrangement of ships operating in a given area. Moreover, there is uncertainty about the accident scenarios potentially emerging from ship encounters. This paper proposes a Bayesian network (BN) model for reasoning under uncertainty for the assessment of accidental cargo oil outflow in a ship-ship collision where a product tanker is struck. The BN combines a model linking impact scenarios to damage extent with a model for estimating the tank layouts based on limited information regarding the ship. The methodology for constructing the model is presented and output for two accident scenarios is shown. The discussion elaborates on the issue of model validation, both in terms of the BN and in light of the adopted uncertainty/bias-based risk perspective. Copyright © 2013 The Authors.

The European Atlantic area has been the scene of a number of extensive shipping incidents with immediate and potential long-term impacts to marine ecosystems. The occurrence of accidental spills at sea requires an effective response that must include a well executed monitoring programme to assess the environmental contamination and damage of the affected marine habitats. Despite a number of conventions and protocols developed by international and national authorities that focused on the preparedness and response to oil and HNS spills, much remains to be done, particularly in relation to the effectiveness of the environmental monitoring programmes implemented after oil and HNS spills. Hence, the present study reviews the status of the environmental monitoring programmes established following the major spill incidents over the last years in European waters, aiming at identifying the key monitoring gaps and drawing priorities for an effective environmental monitoring of accidental spills.

The current study is based on a retrospective investigation of firearm deaths in Diyarbakir, which were autopsied by the Diyarbakir Branch of the Council of Forensic Medicine during the 6- year period. Four hundred-forty four deaths were investigated from January 1996 through December 2001, including homicide (296 cases, 66.7%), suicide (120 cases, 27%) and accidental shootings (28 cases, 6.3%). The age range of all firearm deaths in the study period was 5 to 75 years with a median age of 29.8 years. The majority were in the groups aged 16-25 years (38.7%). In the homicide group, 248 subjects (83.8%) were male, and 48 (16.2%) were female. The 31.1% of the homicide victims were in the group aged at 20-30 years. Of the 120 suicide victims, 56 (46.7%) were in the group aged 16-20 years. The head was by far the favoured site, accounting for 82 (68.3%) deaths: entry wounds in the right temple accounted for 72 of these. Twenty-eight cases were accidental shootings and 18 of them were male (64.3%). Twelve of the 28 accidental victims (42.9%) were in the group aged 0-10 years. The eight cases were due to their own accidental shootings, and the remaining 20 cases were shot by others. Our findings show that the contributing factors for increasing death by firearm are terrorists' activities, traditional habits of obtaining and using guns and blood feuds.

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.

The respective roles of apoptosis and accidental cell death after thermal injury were evaluated in normal human epidermal keratinocytes. By coupling the LIVE/DEAD fluorescence viability assay with the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) method and ultrastructural morphology, these two processes could be distinguished. Cells were grown on glass coverslips with a microgrid pattern so that the results of several staining procedures performed sequentially could be visualized in the same cells after heating at temperatures of up to 72°C for 1 second. After exposure to temperatures of 58 to 59°C, cells died predominantly by apoptosis; viable cells became TUNEL positive, indicating degradation of DNA. After exposure to temperatures of 60 to 66°C, both TUNEL-positive viable cells and TUNEL-positive nonviable cells were observed, indicating that apoptosis and accidental cell death were occurring simultaneously. Cells died almost immediately after exposure to temperatures above 72°C, presumably from heat fixation. The fluorescent mitochondrial probe MitoTracker Orange indicated that cells undergoing apoptosis became TUNEL positive before loss of mitochondrial function. Nucleosomal fragmentation of DNA analyzed by enzyme-linked immunosorbent assay and gel electrophoresis occurred after exposure to temperatures of 58 to 59°C. The characteristic morphological findings of cells undergoing apoptosis, by transmission electron microscopy, included cellular shrinkage, cytoplasmic budding, and relatively intact mitochondria. Depending on temperature and time of exposure, normal human epidermal keratinocytes may die by apoptosis, accidental cell death, or heat fixation. PMID:9708816

Among the main causes of death in our country are car accidents, drowning and accidental burns. Strangulation is a potentially fatal injury and an important cause of homicide and suicide among adults and adolescents. In children, its occurrence is usually accidental. However, in recent years, several cases of accidental strangulation in children around the world have been reported. A 2-year-old male patient was strangled in a car window. The patient was admitted to the pediatric intensive care unit with a Glasgow Coma Scale score of 8 and presented with progressive worsening of respiratory dysfunction and torpor. The patient also presented acute respiratory distress syndrome, acute pulmonary edema and shock. He was managed with protective mechanical ventilation, vasoactive drugs and antibiotic therapy. He was discharged from the intensive care unit without neurological or pulmonary sequelae. After 12 days of hospitalization, he was discharged from the hospital, and his state was very good. The incidence of automobile window strangulation is rare but of high morbidity and mortality due to the resulting choking mechanism. Fortunately, newer cars have devices that stop the automatic closing of the windows if resistance is encountered. However, considering the severity of complications strangulated patients experience, the intensive neuro-ventilatory and hemodynamic management of the pathologies involved is important to reduce morbidity and mortality, as is the need to implement new campaigns for the education of parents and caregivers of children, aiming to avoid easily preventable accidents and to optimize safety mechanisms in cars with electric windows.

Accidental poisoning in childhood: five year urban population study with 15 year analysis of fatality.

Pearn, J; Nixon, J; Ansford, A; Corcoran, A

1984-01-01

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.

2008-05-01

After considering the observed long-term trends in average monthly temperatures distribution in Moscow, the authors evaluated how acute mortality responded to changes in daily average, minimum and maximum temperatures throughout the year, and identified vulnerable population groups, by age and causes of death. A plot of the basic mortality-temperature relationship indicated that this relationship was V-shaped with the minimum around 18 degrees C. Each 1 degree C increment of average daily temperature above 18 degrees C resulted in an increase in deaths from all non-accidental causes by 2.8%, from coronary heart disease by 2.7%, from cerebrovascular diseases by 4.7%, and from respiratory diseases by 8.7%, with a lag of 0 or 1 day. Each 1 degrees C drop of average daily temperature from +18 degrees C to -10 degrees C resulted in an increase in deaths from all non-accidental causes by 0.49%, from coronary heart disease by 0.57%, from cerebrovascular diseases by 0.78%, and from respiratory diseases by 1.5%, with lags of maximum association varying from 3 days for non-accidental mortality to 6 days for cerebrovascular mortality. In the age group 75+ years, corresponding risks were consistently higher by 13-30%. The authors also estimated the increase in non-accidental deaths against the variation of daily temperatures. For each 1 degrees C increase of variation of temperature throughout the day, mortality increased by 0.3-1.9%, depending on other assumptions of the model.

Severe accidental hypothermia is defined as a core temperature below 28 Celsius degrees. Within the last years, the issue of accidental hypothermia and accompanying cardiac arrest has been broadly discussed and European Resuscitation Council (ERC) Guidelines underline the importance of Extracorporeal Rewarming (ECR) in treatment of severely hypothermic victims. The study aimed to evaluate the actual costs of ECR with VA-ECMO and of further management in the Intensive Care Unit of patients admitted to the Severe Accidental Hypothermia Centre in Cracow, Poland. We carried out the economic analysis of 31 hypothermic adults in stage III-IV (Swiss Staging) treated with VA ECMO. Twenty-nine individuals were further managed in the Intensive Care Unit. The actual treatment costs were evaluated based on current medication, equipment, and dressing pricing. The costs incurred by the John Paul II Hospital were then collated with the National Health Service (NHS) funding, assessed based on current financial contract. In most of the cases, the actual treatment cost was greater than the funding received by around 10000 PLN per patient. The positive financial balance was achieved in only 4 (14%) individuals; other 25 cases (86%) showed a financial loss. Performed analysis clearly shows that hospitals undertaking ECR may experience financial loss due to implementation of effective treatment recommended by international guidelines. Thanks to new NHS funding policy since January 2017 such loss can be avoided, what shall encourage hospitals to perform this expensive, yet effective method of treatment.

Impaired theory of mind for moral judgment in high-functioning autism.

High-functioning autism (ASD) is characterized by real-life difficulties in social interaction; however, these individuals often succeed on laboratory tests that require an understanding of another person's beliefs and intentions. This paradox suggests a theory of mind (ToM) deficit in adults with ASD that has yet to be demonstrated in an experimental task eliciting ToM judgments. We tested whether ASD adults would show atypical moral judgments when they need to consider both the intentions (based on ToM) and outcomes of a person's actions. In experiment 1, ASD and neurotypical (NT) participants performed a ToM task designed to test false belief understanding. In experiment 2, the same ASD participants and a new group of NT participants judged the moral permissibility of actions, in a 2 (intention: neutral/negative) × 2 (outcome: neutral/negative) design. Though there was no difference between groups on the false belief task, there was a selective difference in the moral judgment task for judgments of accidental harms, but not neutral acts, attempted harms, or intentional harms. Unlike the NT group, which judged accidental harms less morally wrong than attempted harms, the ASD group did not reliably judge accidental and attempted harms as morally different. In judging accidental harms, ASD participants appeared to show an underreliance on information about a person's innocent intention and, as a direct result, an overreliance on the action's negative outcome. These findings reveal impairments in integrating mental state information (e.g., beliefs, intentions) for moral judgment.

We present the case of an accidental extubation in a prone-positioned patient with a challenging airway because of Klippel-Feil syndrome and previous cervical spine fusions. The surgical procedure was well underway when this occurred, which added substantially to the difficulties produced by this event. We herein highlight the corrective steps we took in our case. We also recommend the need for a comprehensive preoperative briefing with all operating room personnel together with an action plan for how to prevent this particular scenario.

Hypothermia and death caused by hypothermia may be found in a number of fiction works, mainly in novels. In the well-known story “The Little Match Girl” by Hans Christian Andersen, one can notice that the descriptions of the phenomena occurring before the girl’s death are in fact a literary presentation of the pathophysiological mechanisms of the onset of death through accidental hypothermia. This essay presents the medical aspects of the story written by Andersen. PMID:26527999

Accidental Kähler moduli inflation

We study a model of accidental inflation in type IIB string theory where inflation occurs near the inflection point of a small Kähler modulus. A racetrack structure helps to alleviate the known concern that string-loop corrections may spoil Kähler Moduli Inflation unless having a significant suppression via the string coupling or a special brane setup. Also, the hierarchy of gauge group ranks required for the separation between moduli stabilization and inflationary dynamics is relaxed. The relaxation becomes more significant when we use the recently proposed D-term generated racetrack model.

Intoxication with Aconitum napellus is rare in our regions. Aconite alkaloids can cause ventricular arrhythmia by a prolonged activation of sodium channels. Because the margin of safety is low between the analgesic and toxic dose, intoxication is not rare when Aconite is used in herbal medicine. We present a case in which a 39-year-old male was accidentally intoxicated with Aconite. Even though no antidote or adequate therapy is available he was successfully resuscitated.

Lack of awareness and recognition of child maltreatment is the major reason behind underreporting. All victims often interact with the health care system for routine or emergency care. In several research works, non-accidental fractures are the second most common injury in maltreated children and it is represented up to one-third of cases. To determine the incidence of different types of accidental and non-accidental skeletal injuries among children, estimate the severity of injuries according to the modified injury severity score and to determine the degree of fractures either closed or opened (Gustiloe-Anderson open fracture classification). Moreover, identifying fractures resulting from child abuse and neglect. This aimed for early recognition of non-accidental nature of fractures in child maltreatment that can prevent further morbidity and mortality. A descriptive study was carried out on all children (109) with skeletal injuries who were admitted to both Main Alexandria and El-Hadara Orthopedic and Traumatology University Hospitals during six months. History, physical examination and investigations were done for the patients. A detailed questionnaire was taken to diagnose child abuse and neglect. Gustiloe-Anderson open fracture classification was used to estimate the degree of open fractures. Out of 109 children, twelve cases (11%) were categorized as child maltreatment. One case was physical abuse, eight cases (7.3%) were child neglect and three cases (2.8%) were labour exploitation. Road traffic accidents (RTA) was the commonest cause of skeletal injuries followed by falling from height. Regarding falls, they included 4 cases of stair falls in neglected children and another four cases of falling from height (balcony/window). The remaining 36 cases of falls were accidental. The skeletal injuries were in the form of fractures in 99 cases, dislocation in two cases, both fracture and/or dislocation in three cases, and bone deformity from brachial plexus injury in five cases. Fractures of the lower limb (42.2%) and both bones of the forearm (35%) represented the highest incidence of skeletal injuries in children. 54.5% of fractures due to neglect were lower limb fractures due to falling from height. Ninety-nine cases were diagnosed as long bone fractures and classified as the following; eighty patients as closed fractures, six patients as open grade I fractures, three patients as open grade II fractures, three patients as open grade IIIA fractures, four patients as open grade IIIB fractures and three patients as open grade IIIC fractures. Cases of neglect and child abuse represented 11% of all the studied cases, where neglect was the main cause. RTA and falling from height represented the most common cause of skeletal injury in children. Most fractures due to neglect were lower limb fractures resulting from falling from height. This demonstrates the need for early detection of neglect and child maltreatment aiming for early initiation of parental educational programs about child care and safety. Misinterpretation of skeletal injuries due to neglect or abuse can be avoided by proper training of orthopedic and traumatology staff on signs of child neglect and abuse.

Bartlett, Lynne M; Nowak, Madeleine J; Ho, Yikhong

2013-01-01

In Australia, faecal incontinence, the involuntary loss of liquid or solid stool with or without a person's awareness, has been reported in 8% of the South Australian and 11% of the urban New South Wales community-dwelling populations. Studies conducted in 2004 and 2005 reported faecal incontinence in more than 20% of colorectal and urogynaecological clinic patients at Townsville Hospital (a referral centre serving rural North Queensland). This prompted concern regarding the level of faecal incontinence in the community. The aim of this study was to investigate the prevalence of faecal incontinence in the North and Far North Queensland urban and rural communities. The sample size was based on the New South Wales postal surveys (11% prevalence). Higher rates were expected in North/Far North Queensland, so prevalence there was estimated at 12.1% (confidence interval ± 2%, ie the true level to be between 10.1% and 14.1%). The sample for each of the Townsville, Cairns (in Far North Queensland) and rural/remote settings was calculated at 1022. The database for the present study was compiled using a systematic randomised process selecting two private names from each column on each page of the Cairns and Townsville White Pages® (Cairns: 1112 urban, 481 rural, 226 remote; Townsville: 1049 urban, 432 rural, 320 remote). The questionnaire covered personal demographics, health/risk factors, bowel habits, nutrition (fibre and fluid intake) and physical activity. Faecal incontinence was defined as accidental leakage of solid or liquid stool in the past 12 months that was not caused by a virus, medication or contaminated food. To improve the response rate a participation incentive of a chance to win a $250 voucher or one of ten $50 vouchers was offered in the initial mail-out. The initial survey was mailed out in July 2007; two follow-up surveys were mailed out to non-responders in September 2007 and January 2008. One hundred randomly selected non-responders were telephoned in February 2008. A total of 1523 responses provided a 48.1% response rate. Faecal incontinence prevalence was 12.7% (174/1366) with no gender or locality differences. Prevalence increased significantly with age in men (p=0.034), but not in women. Only 10 respondents with faecal incontinence consulted their doctor in the previous year for this reason. Incontinent respondents had significantly more medical conditions including urinary incontinence, coeliac disease, irritable bowel syndrome, injury to the anus, bowel cancer, spinal cord disease, neurological disease and psychiatric problems (all, p< 0.05). Stool-related accidental bowel leakage including faecal incontinence (defined), soiling with flatus or urgency, was 18.2%. An additional 3% were possibly incontinent, having disclosed leakage of mucus, bothersome or passive staining. Of the remaining respondents, 16.2% reported incontinent episodes due to an acute illness, 22.9% could not always differentiate between flatus and stool, and only 35.2% reported neither concerns with nor accidental bowel leakage. There is a high level of untreated faecal incontinence in North/Far North Queensland communities. Demand for treatment will increase because of the ageing population and the expectations of younger, more assertive cohorts.

We compared the cost-effectiveness of two single-dose treatment strategies for adolescents with uncomplicated Neisseria gonorrhoeae cervicitis. We used a cost-effectiveness decision- analysis model to compare the two methods: the standard, ceftriaxone 125 mg given by IM injection; and an alternative, cefixime 400 mg given orally. The effect of the costs associated with the risk of accidental needlestick during IM administration was also evaluated. Key baseline assumptions (with ranges, when tested) were from the literature or costs to our hospital. These included ceftriaxone, $8.60 per dose; cefixime, $4.67 per dose; ceftriaxone efficacy, 98% (range, 94.9% to 100%); cefixime efficacy, 97% (94.1% to 100%); and a 15% probability of pelvic inflammatory disease (PID) related to failed treatment. We included costs for PID necessitating hospitalization, disseminated gonococcal infection, infertility, and ectopic pregnancy. Assumptions related to accidental needlestick included the rate of needlesticks with the disposable syringe, 6.9 per 100,000 injections (range, 0 to 69); cost of accidental needlestick to hospital; risk of HIV seroconversion after needlestick exposure to HIV-infected blood, .36% (range, 0% to .86%); rate of HIV infection in 15- to 19-year-olds attending sexually transmitted diseases clinics, .4% (range, 0 to 5); and lifetime treatment costs for a person with HIV. At baseline values the model favored ceftriaxone ($45 per patient) or cefixime ($59 per patient). However, over the range of efficacy of both drugs, two-way sensitivity analysis revealed no consistent cost advantage for either drug. The model was also insensitive to the economic effects associated with the risk of accidental needlestick during IM injection. over the range of efficacy by the 95% confidence intervals of both drugs, our analysis demonstrated no clear cost advantage for either. The economic effects of accidental needlestick do not change this conclusion. Compared with the IM alternative, oral cefixime is painless to the patient and simpler for the practitioner to administer. Oral cefixime also eliminates the psychologic effects associated with needlesticks in health care workers. For these reasons, we favor the use of oral cefixime for uncomplicated gonococcal cervicitis in adolescents.

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 < 0.05) with age: 8 to 13 > 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p < 0.05). Evaluation of only the nonaccidental injuries (n = 2,565) showed that the oldest categories (19-22 and 23-30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p < 0.001). Two thirds of the injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to "dropping" and "pinching" in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p < 0.001). The study findings indicate that children have lower risk of resistance training-related joint 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.

Understanding drug-related mortality in released prisoners: a review of national coronial records.

The prisoner population is characterised by a high burden of disease and social disadvantage, and ex-prisoners are at increased risk of death following release. Much of the excess mortality can be attributed to an increased risk of unnatural death, particularly from drug overdose; however, relatively few studies have investigated the circumstances surrounding drug-related deaths among released prisoners. This study aimed to explore and compare the circumstances of death for those who died from accidental drug-related causes to those who died from all other reportable causes. A nationwide search of the Australian National Coroners Information System (NCIS) was conducted to identify reportable deaths among ex-prisoners from 2000 to 2007. Using a structured coding form, NCIS records for these cases were interrogated to explore causes and circumstances of death. Coronial records for 388 deceased ex-prisoners were identified. Almost half of these deaths were a result of accidental drug-related causes (45%). The majority of accidental drug-related deaths occurred in a home environment, and poly-substance use at or around the time of death was common, recorded in 72% of drug-related deaths. Ex-prisoners who died of accidental drug-related causes were on average younger and less likely to be Indigenous, born in Australia, married, or living alone at or around the time of death, compared with those who died from all other reportable causes. Evidence of mental illness or self-harm was less common among accidental drug-related deaths, whereas evidence of previous drug overdose, injecting drug use, history of heroin use and history of drug withdrawal in the previous six months were more common. Drug-related deaths are common among ex-prisoners and often occur in a home (vs. public) setting. They are often associated with use of multiple substances at or around the time of death, risky drug-use patterns, and even among this markedly disadvantaged group, extreme social disadvantage. These findings reflect the complex challenges facing prisoners upon release from custody and indicate a need to consider drug overdose within the wider framework of ex-prisoner experiences, so that preventive programmes can be appropriately structured and targeted.

The incidence of hypothermia is difficult to evaluate, and the data concerning the morbidity and mortality rates do not seem to fully represent the problem. The aim of the study was to estimate the actual prevalence of accidental hypothermia in Poland, as well as the methods of diagnosis and management procedures used in emergency rooms (ERs). A specially designed questionnaire, consisting of 14 questions, was mailed to all the 223 emergency rooms (ER) in Poland. The questions concerned the incidence, methods of diagnosis and risk factors, as well as the rewarming methods used and available measurement instruments. The analysis involved data from 42 ERs providing emergency healthcare for the population of 5,305,000. The prevalence of accidental hypothermia may have been 5.05 cases per 100.000 residents per year. Among the 268 cases listed 25% were diagnosed with codes T68, T69 or X31, and in 75% hypothermia was neither included nor assigned a code in the final diagnosis. The most frequent cause of hypothermia was exposure to cold air alongside ethanol abuse (68%). Peripheral temperature was measured in 57%, core temperature measurement was taken in 29% of the patients. Peripheral temperature was measured most often at the axilla, while core temperature measurement was predominantly taken rectally. Mild hypothermia was diagnosed in 75.5% of the patients, moderate (32-28°C) in 16.5%, while severe hypothermia (less than 28°C) in 8% of the cases. Cardiopulmonary resuscitation was carried out in 7.5% of the patients. The treatment involved mainly warmed intravenous fluids (83.5%) and active external rewarming measures (70%). In no case was extracorporeal rewarming put to use. The actual incidence of accidental hypothermia in Polish emergency departments may exceed up to four times the official data. Core temperature is taken only in one third of the patients, the treatment of hypothermic patients is rarely conducted in intensive care wards and extracorporeal rewarming techniques are not used. It may be expected that personnel education and the development of management procedures will brighten the prognosis and increase the survival rate in accidental hypothermia.

Background Elder abuse is under-recognized by Emergency Department (ED) providers, largely due to challenges distinguishing between abuse and accidental trauma. Objective To describe patterns and circumstances surrounding elder abuse-related and potentially abuse-related injuries in ED patients independently known to be physical elder abuse victims. Methods ED utilization of community-dwelling victims of physical elder abuse in New Haven, CT from 1981-1994 was analyzed previously. Cases were identified using Elderly Protective Services data matched to ED records. 66 ED visits were judged to have high probability of being related to elder abuse and 244 of indeterminate probability. We re-examined these visits to assess whether they occurred due to injury. We identified and analyzed in detail 31 injury-associated ED visits from 26 patients with high probability of being related to elder abuse and 108 visits from 57 patients with intermediate probability and accidental injury. Results Abuse-related injuries were most common on upper extremities (45% of visits) and lower extremities (32%), with injuries on head or neck noted in 13 visits (42%). Bruising was observed in 39% of visits, most commonly on upper extremities. 42% of purportedly accidental injuries had suspicious characteristics, with the most common suspicious circumstance being injury occurring >1 day prior to presentation and the most common suspicious injury pattern being maxillofacial injuries. Conclusion Victims of physical elder abuse commonly have injuries on upper extremities, head, and neck. Suspicious circumstances and injury patterns may be identified and are commonly present when victims of physical elder abuse present with purportedly accidental injuries. PMID:26810019

The role of environmental accidental risk assessment in the process of granting development consent.

PubMed

Kontic, Branko; Gerbec, Marko

2009-11-01

Environmental impact assessment (EIA) is a procedure that must be followed for certain types of development before they are granted development consent. The procedure requires the developer to compile an environmental impact report (EIR) describing the likely significant effects of the project on the environment. A regulatory requirement in Slovenia is that an accidental risk assessment for a new installation should be a part of an EIR. The article shows how risk assessment (RA) related to accidental release of methylene diphenyl diisocyanate (MDI) or a polyvalent alcohol mixture from a new planned unit of a chemical factory in the Alpine region of Slovenia was performed in the framework of an EIA for the purpose of obtaining a construction permit. Two accidental scenarios were considered: (a) a spill of 20 m(3) of MDI or polyvalent alcohol mixture into the river Soca (the river runs close to the chemical factory) and (b) a fire in the warehouse storing the raw material, where emission of toxic gases HCN, NO(x), and CO is expected during combustion of MDI. One of the most important results of this case is the agreement among the developer, the competent authority, and a consultant in the field of EIA and RA to positively conclude the licensing process despite the absence of formal (regulatory) limit values for risk. It has been approved that transparent, reasonably uncertain, and semi-quantitative environmental risk assessment is an inevitable component of an EIA, and an essential factor in informed, licensing-related decision making.

Accidents constitute one of the greatest risks to children, yet there are few medical reports that discuss the subject of accidental asphyxia. However, a systematic analysis of all documented cases in Germany over the years 2000-2008 has now been conducted, aiming at identifying patterns of accidental asphyxia, deducing findings, defining avoidance measures and recommending ways of increasing product safety and taking possible precautions. The analysis is based on a detailed retrospective analysis of all 91 relevant autopsy reports from 24 different German forensic institutes. A variety of demographic and morphological data was systematically collected and analysed. In 84 of the 91 cases, the sex of the victim was reported, resulting in a total of 57 boys (68 %) and 27 girls (32 %). The age spread ranged between 1 day and 14 years, with an average of 5.9 years. Most accidents occurred in the first year of life (20 %) or between the ages of 1 and 2 years (13 %). In 46 % of cases, the cause of death was strangulation, with the majority occurring in the home environment. In 31 % of all cases, the cause of death was positional asphyxia, the majority resulting from chest compression. In 23 % of cases, the cause of death was aspiration, mainly of foreign bodies. Today, accidental asphyxiation is a rare cause of death in children in Germany. Nevertheless, the majority of cases could have been avoided. Future incidence can be reduced by implementing two major precautions: increasing product safety and educating parents of potentially fatal risks. Specific recommendations relate to children's beds, toys and food.

[Inadvertent injection of succinylcholine as an epidural test dose].

PubMed

Pourzitaki, Chryssa; Tsaousi, Georgia; Logotheti, Helena; Amaniti, Ekaterini

Epidural action of neuromuscular blocking agents could be explained under the light of their physicochemical characteristics and epidural space properties. In the literature there are few cases of accidental neuromuscular agent's epidural administration, manifesting mainly with neuromuscular blockade institution or fasciculations. We report a case of accidental succinylcholine administration as an epidural test dose, in a female patient undergoing scheduled laparotomy, under combined general and epidural anesthesia. Approximately 2min after the succinylcholine injection the patient complained for shortness of breath, while mild fasciculations appeared in her trunk and face, managed by immediate general anesthesia institution. With the exception of a relatively longer duration of neuromuscular blockade compared with intravenous administration, no neurological or cardiovascular sequelae or other symptoms of local or systemic toxicity were observed. Oral administration of diazepam seems to lessen the adverse effects from accidental epidural administration of succinylcholine. The meticulous and discriminative labeling of syringes, as well as keeping persistent cautions during all anesthesia procedures remains of crucial importance.

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.

Scrap metals industry perspective on radioactive materials.

PubMed

Turner, Ray

2006-11-01

With more than 80 reported/confirmed accidental melts worldwide since 1983 and still counting, potential contamination by radioactive materials remains as a major concern among recycled scrap and steel companies. Some of these events were catastrophic and have cost the industry millions of dollars in business and, at the same time, resulted in declining consumer confidence. It is also known that more events with confirmed radioactive contamination have occurred that involve mining of old steel slag and skull dumps. Consequently, the steel industry has since undergone massive changes that incurred unprecedented expenses through the installation of radiation monitoring systems in hopes of preventing another accidental melt. Despite such extraordinary efforts, accidental melts continue to occur and plague the industry. One recent reported/confirmed event occurred in the Republic of China in 2004, causing the usual lengthy shutdown for expensive decontamination efforts before the steel mill could resume operations. With this perspective in mind, the metal industry has a long-standing opposition to the release of radioactive materials of any kind to commerce for fear of contamination and the potential consequences.

Choking in adults can prove fatal, despite resuscitation attempts. The manner of death can be natural, homicide or accident. When a death is due to choking, one must consider what conditions contributed to or predisposed the person to choking (eg. alcohol, drugs and physical and mental impairments). Homicidal deaths by choking are relatively uncommon, being more frequently accidental. The diagnosis of death by choking is made at autopsy when the airway is found occluded. If the individual had an occluded airway and the object or food was removed during resuscitation, the only way to make the diagnosis would be on the history. Here, we present a case of asphyxia (accidental or suicidal) by choking on a handkerchief in a patient with a long history of schizophrenia. The woman had attempted a previous suicide driven by evil spirits coming from inside her body, especially from the head and throat; in order to "shut-up" the spirit, she was trying to suffocate it with her hands or by a belt from her pants.

Accidental Peccei-Quinn Symmetry Protected to Arbitrary Order

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.

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 Beam Losses and Protection in the LHC

NASA Astrophysics Data System (ADS)

Schmidt, R.; Working Group On Machine Protection

2005-06-01

At top energy (proton momentum 7 TeV/c) with nominal beam parameters, each of the two LHC proton beams has a stored energy of 350 MJ threatening to damage accelerator equipment in case of accidental beam loss. It is essential that the beams are properly extracted onto the dump blocks in case of failure since these are the only elements that can withstand full beam impact. Although the energy stored in the beams at injection (450 GeV/c) is about 15 times smaller compared to top energy, the beams must still be properly extracted in case of large accidental beam losses. Failures must be detected at a sufficiently early stage and initiate a beam dump. Quenches and power converter failures will be detected by monitoring the correct functioning of the hardware systems. In addition, safe operation throughout the cycle requires the use of beam loss monitors, collimators and absorbers. Ideas of detection of fast beam current decay, monitoring of fast beam position changes and monitoring of fast magnet current changes are discussed, to provide the required redundancy for machine protection.

Impact of the LHC beam abort kicker prefire on high luminosity insertion and CMS detector performance

The effect of possible accidental beam loss in LHC on the IP5 insertion elements and CMS detector is studied via realistic Monte Carlo simulations. Such beam loss could be the consequence of an unsynchronized abort or in worst case an accidental prefire of one of the abort kicker modules. Simulations with the STRUCT code show that this beam losses would take place in the IP5 inner and outer triplets. MARS simulations of the hadronic and electro-magnetic cascades induced in such an event indicate severe heating of the inner triplet quadrupoles. In order to protect the IP5 elements, two methods aremore » proposed: a set of shadow collimators in the outer triplet and a prefired module compensation using a special module charged with an opposite voltage (antikicker). The remnants of the accidental beam loss entering the experimental hall have been used as input for FLUKA simulations in the CMS detector. It is shown that it is vital to take measures to reliably protect the expensive CMS tracker components.« less

Awareness of crop biosecurity and phytosanitation has been heightened since 9/11 and the unresolved anthrax releases in October 2001. Crops are highly vulnerable to accidental or deliberate introductions of crop pathogens from outside U.S. borders. Strategic thinking about protection against deliberate or accidental release of a plant pathogen is an urgent priority. Rapid detection will be the key to success. This review summarizes recent progress in the development of rapid real-time PCR protocols and evaluates their effectiveness in a proposed nationwide network of diagnostic laboratories that will facilitate rapid diagnostics and improved communication.

Galloway, T.R.

1980-04-01

An improvement is described 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. 1 fig.

Carbon monoxide (CO) is the cause of a significant percentage of fatal poisonings in many countries. It is known that fatalities resulting from CO poisoning are underreported and/or misclassified. Carbon monoxide exposure while driving can occur due to faulty exhaust systems, defective ventilation systems, emission from other vehicles, and even cigarette smoking. We report the case of a 23-year-old woman who was involved in a low-speed motor vehicle collision and was found unresponsive in her vehicle due to CO poisoning. A review of the literature revealed rare vehicle-related accidental CO poisonings.

The Songaksan tuff ring, Jeju Island, Korea, which erupted ca. 3.7 ka BP in a coastal setting, provides an unusual opportunity to study the processes of phreatomagmatic eruption and the formation of a diatreme because of the exceptionally well-preserved ejecta beds and well-known subsurface geology. The tuff sequence can be divided into four units (A to D), which have distinctly different accidental componentry (quartz-rich vs. quartz-poor), grain surface features (abraded and ash-coated vs. unabraded and uncoated), and chemical compositions of juvenile particles. The basal tephra bed of unit A, which probably erupted after the removal of the relatively hard shallow-level (<120 m deep) substrate by initial cratering, comprises only unabraded and uncoated grains and contains abundant relatively deep-derived (>120 m deep) accidental grains, suggesting that the early erupted tephra had not yet experienced recycling and pre-eruption mixing in the diatreme. On the other hand, the overlying tephra beds of units A, B, and D contain an abundance of abraded and ash-coated juvenile/accidental grains, suggesting that the tephra comprised significant proportions of "recycled" or "premixed" materials from previous eruptions or subsurface explosions, which participated in the explosion-driven mixing in the diatreme before eventual ejection from the diatreme. Unit C is unusual in that it comprises extremely rare accidental grains and ash-coated juvenile/accidental grains. We interpret that the supply of solid materials, either accidental or juvenile, to the diatreme was greatly reduced because of temporary stabilization of the diatreme and the reduction in magma flux to the diatreme. The diatreme is therefore envisaged to have been filled with a water-saturated slurry, in which particle abrasion and adhesion were inhibited. We also infer that the diatreme fill was temporarily removed by a powerful explosion before eruption of unit C on the basis of the near absence of the tephra grains from earlier eruptions throughout the tephra beds of unit C. The ratio of tachylite to sideromelane grains generally increases up-section of the tuff sequence with two abrupt drops across the tuff unit boundaries. These variations are coincident with the changes in the chemical composition of juvenile particles, suggesting an overall decrease in magma flux punctuated by brief increases in magma flux associated with the arrival of new magma batches. The textural and compositional variations of the Songaksan tuff ring suggest that there can be significant variability in diatreme processes even during a purely phreatomagmatic eruption of a tuff ring, including removal and renewal of the diatreme fill, and that there is still much room for further investigation of the diatreme processes from the ejecta beds in order to make the current diatreme model more robust.

The development of the Bulgarian Emergency Response System (BERS) for short term forecast in case of accidental radioactive releases to the atmosphere has been started in the mid 1990's [1]. BERS comprises of two main parts - operational and accidental, for two regions 'Europe' and 'Northern Hemisphere'. The operational part runs automatically since 2001 using the 72 hours meteorological forecast from DWD Global model, resolution in space of 1.5o and in time - 12 hours. For specified Nuclear power plants (NPPs), 3 days trajectories are calculated and presented on NIMH's specialized Web-site (http://info.meteo.bg/ews/). The accidental part is applied when radioactive releases are reported or in case of emergency exercises. BERS is based on numerical weather forecast information and long-range dispersion model accounting for the transport, dispersion, and radioactive transformations of pollutants. The core of the accidental part of the system is the Eulerian 3D dispersion model EMAP calculating concentration and deposition fields [2]. The system is upgraded with a 'dose calculation module' for estimation of the prognostic dose fields of 31 important radioactive gaseous and aerosol pollutants. The prognostic doses significant for the early stage of a nuclear accident are calculated as follows: the effective doses from external irradiation (air submersion + ground shinning); effective dose from inhalation; summarized effective dose and absorbed thyroid dose [3]. The output is given as 12, 24, 36, 48, 60 and 72 hours prognostic dose fields according the updated meteorology. The BERS was upgraded to simulate the dispersion of nuclear materials from Fukushima NPP [4], and results were presented in NIMH web-site. In addition BERS took part in the respective ENSEMBLE exercises to model 131I and 137Cs in Fukushima source term. In case of governmental request for expertise BERS was applied for environmental impact assessment of hypothetical accidental transboundary radioactive pollution. The consequences were estimated based on the worst emission scenario for the existing basic reactor type, selection of real meteorological forecast conditions, favoring the direct transport of the contaminated air masses to the territory of the country in consideration. In the present work BERS is used to estimate the worst case accidental scenario impact from a possible new unit of Paks Nuclear Power Plant, Hungary over the territory of Bulgaria. 1.

Glyphosate: environmental contamination, toxicity and potential risks to human health via food contamination.

PubMed

Glyphosate has been the most widely used herbicide during the past three decades. The US Environmental Protection Agency (EPA) classifies glyphosate as 'practically non-toxic and not an irritant' under the acute toxicity classification system. This classification is based primarily on toxicity data and due to its unique mode of action via a biochemical pathway that only exists in a small number of organisms that utilise the shikimic acid pathway to produce amino acids, most of which are green plants. This classification is supported by the majority of scientific literature on the toxic effects of glyphosate. However, in 2005, the Food and Agriculture Organisation (FAO) reported that glyphosate and its major metabolite, aminomethylphosphonic acid (AMPA), are of potential toxicological concern, mainly as a result of accumulation of residues in the food chain. The FAO further states that the dietary risk of glyphosate and AMPA is unlikely if the maximum daily intake of 1 mg kg(-1) body weight (bw) is not exceeded. Research has now established that glyphosate can persist in the environment, and therefore, assessments of the health risks associated with glyphosate are more complicated than suggested by acute toxicity data that relate primarily to accidental high-rate exposure. We have used recent literature to assess the possible risks associated with the presence of glyphosate residues in food and the environment.

High costs and overcrowding of dialysis centres are leading to a global crisis in health care provision. We are developing slow nocturnal home hemodialysis (SNHHD) in which patients dialyze for eight to 10 hours during sleep five to seven nights per week. Vascular access is by means of the Cook silastic jugular catheter. Special precautions are taken to prevent accidental disconnection and air embolism. Dialysis functions are remotely monitored on computer via a modem by trained staff. Five patients have completed five to seven weeks of training and have been successfully performing SNHHD single-handedly (three out of five patients live alone) for 14, 14, 11, 10 and four months respectively. All have discontinued their phosphate binders and increased dietary phosphate intake. Compared with conventional hemodialysis (CHD) results, average pre-dialysis urea and creatinine levels are remarkably reduced to 9.6 mmol/l and 486 umol/l respectively. The average cumulative weekly Kt/V for CHD is 5.0 as compared to 7.7 while on SNHHD. Four out of five patients report sleeping soundly and experience greatly increased energy and stamina. Their days are entirely free. Repeated in-situ re-use of the dialyzer and blood lines will reduce the patient's work and make SNHHD a very inexpensive modality. SNHHD appears to be a widely applicable treatment with many advantages to both the patient and the health care system.

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 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). One of the main tasks of this project was 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 introduces the project models used and presents the results of task 2. The results of task 1 are presented by Baumann-Stanzer and Stenzel in this session. For the purpose of this study the following models were tested and compared: ALOHA (Areal Location of Hazardous atmosphere, EPA), MEMPLEX (Keudel av-Technik GmbH), Breeze (Trinity Consulting), SAFER System, SAM (Engineering office Lohmeyer), COMPAS. A set of reference scenarios for Chlorine, Ammoniac, Butane and Petrol were proceed in order to reliably predict and estimate the human exposure during the event. The models simulated the accidental release from the mentioned above gases and estimates the potential toxic areas. Since the inputs requirement differ from model to model, and the outputs are based on different criteria for toxic areas and exposure, a high degree of caution in the interpretation of the model results is needed.

The possibility of accidental industrial chemical releases has generated considerable recent attention. One area requiring research for emergency planning is the development of safe exposure concentrations for the public in the event of an inadvertent release. The United States Environmental Protection Agency (EPA) has established a list of extremely hazardous substances and suggested that the toxicity ranking for 92 hazardous materials could be based on the "immediately dangerous to life or health" (IDLH) values developed by the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA). Eighty-four compounds with IDLH values for which published toxicologic data were available were reviewed to assess the appropriateness of applying such values to accidental release situations. When compared with 30-min animal median lethal concentrations (LC50s), 18 of the IDLHs reviewed were in the same range as lethal levels for animals. For 45 compounds the IDLH values were comparable to concentrations producing severe toxic effects (specifically, unconsciousness, incapacitation, or intolerable irritation). Where available, emergency planning guidelines for the military were compared to IDLHs, and in all 31 cases, the IDLHs exceeded the military exposure guidelines. Twenty compounds also were found to pose a potential cancer risk according to common regulatory guidelines, even under the assumption of a single, 30-min exposure at the IDLH concentration. In addition, the high degree of variability (four orders of magnitude) in the relationship of IDLH values to outcomes of lethality or severe toxicity suggests that the use of IDLH values as emergency planning guidelines for accidental releases is questionable.(ABSTRACT TRUNCATED AT 250 WORDS)

Objective: To estimate future excess mortality attributable to cold spells in Guangzhou, China. Methods: We collected the mortality data and metrological data from 2009-2013 of Guangzhou to calculated the association between cold spell days and non-accidental mortality with GLM model. Then we projected future daily average temperatures (2020-2039 (2020s) , 2050-2069 (2050s) , 2080-2099 (2080s) ) with 5 GCMs models and 2 RCPs (RCP4.5 and RCP8.5) to identify cold spell days. The baseline period was the 1980s (1980-1999). Finally, calculated the yearly cold spells related excess death of 1980s, 2020s, 2050s, and 2080s with average daily death count of non-cold spell days, exposure-response relationship, and yearly number of cold spell days. Results: The average of daily non-accidental mortality in Guangzhou from 2009 to 2013 was 96, and the average of daily average was 22.0 ℃. Cold spell days were associated with 3.3% (95% CI: 0.4%-6.2%) increase in non-accidental mortality. In 1980s, yearly cold spells related deaths were 34 (95% CI: 4-64). In 2020s, the number will increase by 0-10; in 2050s, the number will increase by 1-9; and in 2080s, will increase by 1-9 under the RCP4.5 scenario. In 2020s, the number will increase by 0-9; in 2050s, the number will increase by 1-6; and in 2080s, will increase by 0-11 under the RCP8.5 scenario. Conclusion: The cold spells related non-accidental deaths in Guangzhou will increase in future under climate change.

Background 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. Methods 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. Results 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. Conclusions The authors recommend that non symptomatic or slightly exposed patients do not need any specific treatment or symptomatic treatment is sufficient.

Accidental Outcomes Guide Punishment in a “Trembling Hand” Game

How do people respond to others' accidental behaviors? Reward and punishment for an accident might depend on the actor's intentions, or instead on the unintended outcomes she brings about. Yet, existing paradigms in experimental economics do not include the possibility of accidental monetary allocations. We explore the balance of outcomes and intentions in a two-player economic game where monetary allocations are made with a “trembling hand”: that is, intentions and outcomes are sometimes mismatched. Player 1 allocates $10 between herself and Player 2 by rolling one of three dice. One die has a high probability of a selfish outcome, another has a high probability of a fair outcome, and the third has a high probability of a generous outcome. Based on Player 1's choice of die, Player 2 can infer her intentions. However, any of the three die can yield any of the three possible outcomes. Player 2 is given the opportunity to respond to Player 1's allocation by adding to or subtracting from Player 1's payoff. We find that Player 2's responses are influenced substantially by the accidental outcome of Player 1's roll of the die. Comparison to control conditions suggests that in contexts where the allocation is at least partially under the control of Player 1, Player 2 will punish Player 1 accountable for unintentional negative outcomes. In addition, Player 2's responses are influenced by Player 1's intention. However, Player 2 tends to modulate his responses substantially more for selfish intentions than for generous intentions. This novel economic game provides new insight into the psychological mechanisms underlying social preferences for fairness and retribution. PMID:19707578

Abusive head trauma and accidental head injury: a 20-year comparative study of referrals to a hospital child protection team

Aim To describe children referred for suspected abusive head trauma (AHT) to a hospital child protection team in Auckland, New Zealand. Methods Comparative review of demographics, histories, injuries, investigations and diagnostic outcomes for referrals under 15 years old from 1991 to 2010. Results Records were available for 345 children. Referrals increased markedly (88 in the first decade, 257 in the second), but the diagnostic ratio was stable: AHT 60%, accidental or natural 29% and uncertain cause 11%. The probability of AHT was similar regardless of socio-economic status or ethnicity. In children under 2 years old with accidental head injuries (75/255, 29%) or AHT (180/255, 71%), characteristics of particular interest for AHT included no history of trauma (88/98, 90%), no evidence of impact to the head (84/93, 90%), complex skull fractures with intracranial injury (22/28, 79%), subdural haemorrhage (160/179, 89%) and hypoxic ischaemic injury (38/39, 97%). In children over 2 years old, these characteristics did not differ significantly between children with accidental head injuries (21/47, 45%) and AHT (26/47, 55%). The mortality of AHT was higher in children over 2 years old (10/26, 38%) than under 2 years (19/180, 11%). Conclusions The striking increase in referrals for AHT probably represents increasing incidence. The decision to refer a hospitalised child with a head injury for assessment for possible AHT should not be influenced by socio-economic status or ethnicity. Children over 2 years old hospitalised for AHT are usually injured by mechanisms involving impact and should be considered at high risk of death. PMID:26130384

Extrapyramidal symptoms following accidental ingestion of risperidone in a child.

To describe the development of extrapyramidal symptoms (EPS) precipitated by an accidental overdose of risperidone in a 3.5-year-old boy. The boy presented to the emergency department with bilateral upward eye gaze, jerky movements of his extremities, and motor restlessness following an accidental ingestion of a single 4-mg risperidone tablet. Decontamination with NaCl 0.9% lavage and activated charcoal with sorbitol was performed. His symptoms responded immediately to intravenous diphenhydramine (on 3 different occasions) during his first 9.5 hours of hospitalization. He experienced no additional EPS, and was discharged home approximately 33 hours following initial presentation. At home, he received three oral doses of diphenhydramine in the 24 hours following hospital discharge because of hand tremor, total body shivering, and eye wandering. These signs resolved without further complications. Although the incidence of EPS associated with therapeutic risperidone use is low, its occurrence following overdose is less clearly defined. This represents the first published case, to our knowledge, of risperidone overdose in a child and highlights the potential for dystonic reactions at low doses in this population. Seven intentional overdoses of risperidone in adults (aged 21-68 y) have been reported in the literature and are reviewed. Amounts ingested ranged from 5 to 270 mg. All adult patients appeared to have a relatively benign course. Reported symptoms included drowsiness, slurred speech, altered levels of consciousness, hypertension, tachycardia, electrocardiogram abnormalities, atypical motor behavior, tremors, and other EPS (not specified). Accidental ingestion of low doses of risperidone can cause EPS in children that may respond well to an anticholinergic agent. Overdose management includes gastrointestinal lavage, activated charcoal with cathartic, cardiovascular monitoring, and supportive therapy.

While the relevance of falls in raising the risk of fractures, hospitalization and disability in older age is well recognized, the factors influencing the onset of fractures and the need for ward admission after a fall have yet to be fully elucidated. We investigated which factors and fall dynamics were mainly associated with fall-related injuries and hospitalization among elderly persons accessing the Emergency Department (ED) following a fall. The study involved 2144 older subjects who accessed the ED after a fall. Data on the fall´s nature and related injuries, ward admissions, history of falls, dementia, and medical therapies were examined for all patients. Considering dynamics, we distinguished accidental falls (due to interaction with environmental hazards while in motion) and falls from standing (secondary to syncope, lipothymia, drop attack, or vertigo). The overall prevalence of fractures in our population did not differ significantly with advancing age, though hip fractures were more common in the oldest, and upper limb fractures in the youngest patients. Falls from standing were associated with polypharmacy and with higher ward admission rate despite a lower fractures´ prevalence than accidental falls. The chances of fall-related fractures were more than fourfold as high for accidental dynamics (OR=4.05, 95%CI:3.10-5.29, p<0.0001). Ward admission was associated with polypharmacy, dementia, anticoagulants´ use and fall-related fractures (OR=6.84, 95%CI:5.45-8.58, p<0.0001), while it correlated inversely with accidental fall dynamics. Outcomes of falls in older age depend not only on any fall-related injuries, but also on factors such as polypharmacy, cognitive status and fall dynamics. Copyright © 2017 Elsevier B.V.

On regional level, and especially in areas with potential diverse sources of industrial pollutants, the risk assessment of impact on environment and population is critically important. During normal operations, the risk is minimal. However, during accidental situations, the risk is increased due to releases of harmful pollutants into different environments such as water, soil, and atmosphere where it is following processes of continuous transformation and transport. In this study, the Enviro-HIRLAM (Environment High Resolution Limited Area Model) was adapted and employed for assessment of scenarios with accidental and continuous emissions of sulphur dioxide (SO2) for selected case studies during January of 2010. The following scenarios were considered: (i) control reference run; (ii) accidental release (due to short-term 1 day fire at oil storage facility) occurred at city of Atyrau (Kazakhstan) near the northern part of the Caspian Sea; and (iii) doubling of original continuous emissions from three locations of metallurgical enterprises on the Kola Peninsula (Russia). The implemented aerosol microphysics module M7 uses 5 types - sulphates, sea salt, dust, black and organic carbon; as well as distributed in 7 size modes. Removal processes of aerosols include gravitational settling and wet deposition. As the Enviro-HIRLAM model is the on-line integrated model, both meteorological and chemical processes are simultaneously modelled at each time step. The modelled spatio-temporal variations for meteorological and chemical patterns are analyzed for both European and Kazakhstan regions domains. The results of evaluation of sulphur dioxide concentration and deposition on main populated cities, selected regions, countries are presented employing GIS tools. As outcome, the results of Enviro-HIRLAM modelling for accidental release near the Caspian Sea are integrated into the RANDOM (Risk Assessment of Nature Detriment due to Oil spill Migration) system.

In view of the importance of knowing the circumstances associated with external causes (accidents and violence), this study analyzes the profile of the victims and their families as to the intentionality of the event (intentional or accidental). Cross-sectional study, which population comprise children, adolescents, and young people (age 0 to 24) who lived in Cuiabá, MT, and died from external causes in 2009. The data, processed by the Epi-Info software, were taken from the Declarations of Death and interviews with the families of the victims. The nonparametric chi-square test showed statistically significant differences between accidental and intentional deaths by sex and the type of accident or violence, the occurrence of the previous event external cause, parental education, family type, income, responsible for supporting the house, mother's age and caregiver. Among the victims, male participation (88.7 %) stands out compared to female (11.3 %). 50.0% of the deaths of females were accidental and 50.0% intentional; 68.2% of the deaths of males were intentional, 29.1% accidental and 2.7% from undetermined intent. Among the intentional deaths, 72.5% of the victims had already suffered violence. As the degree of instruction of the parents increases, intentional deaths decrease. The proportion of reconstituted/fragmented families is higher for fatal accidents. Intentional causes increase as family income decreases and the age of the parents increases. The agglomeration of people in the homes is higher for intentional deaths. Analizing the profiles of families and victims as to the intentionality of the event allows directing local prevention and control policies.

Background Although there is concern that food allergic reactions may negatively affect the natural history of food allergy, the impact of reactions on food-specific IgE (sIgE) or skin prick tests is unknown. Objective To measure the effects of allergic reactions on SPT wheal size and sIgE concentrations to milk, egg and peanut. Methods Participants included 512 infants with likely milk or egg allergy enrolled in a multi-center observational study. Changes in sIgE and SPT to milk, egg, and peanut were measured before and after oral food challenge (OFC) or accidental exposure for 377 participants. Results Median age of the cohort at time of analysis was 8.5 years (67% male). There were no statistically significant changes in sIgE or SPT after positive OFC to milk, egg, or peanut (n=20-27 for each food). Change in sIgE and SPT was measured after 446 and 453 accidental exposure reactions, respectively. Median change in sIgE decreased by 0.33 kUA/L (p<.01) after milk and by 0.34 (p<.01) after egg reactions; but no other statistically significant changes in sIgE or SPT were observed for milk, egg, or peanut. Limiting analysis to only participants with diagnostic testing done within 6 months of an accidental exposure reaction, peanut SPT increased 1.75 mm (p<.01), but a significant increase was not noted when all participants with testing done within 12 months were considered. Conclusions The results suggest that reactions from OFCs and accidental exposure are not associated with increases in sensitization among children allergic to milk, egg or peanut. PMID:26718150

Elder abuse is under-recognized by emergency department (ED) providers, largely due to challenges distinguishing between abuse and accidental trauma. To describe patterns and circumstances surrounding elder abuse-related and potentially abuse-related injuries in ED patients independently known to be physical elder abuse victims. ED utilization of community-dwelling victims of physical elder abuse in New Haven, CT from 1981-1994 was analyzed previously. Cases were identified using Elderly Protective Services data matched to ED records. Sixty-six ED visits were judged to have high probability of being related to elder abuse and 244 were of indeterminate probability. We re-examined these visits to assess whether they occurred due to injury. We identified and analyzed in detail 31 injury-associated ED visits from 26 patients with high probability of being related to elder abuse and 108 visits from 57 patients with intermediate probability and accidental injury. Abuse-related injuries were most common on upper extremities (45% of visits) and lower extremities (32%), with injuries on head or neck noted in 13 visits (42%). Bruising was observed in 39% of visits, most commonly on upper extremities. Forty-two percent of purportedly accidental injuries had suspicious characteristics, with the most common suspicious circumstance being injury occurring more than 1 day prior to presentation, and the most common suspicious injury pattern being maxillofacial injuries. Victims of physical elder abuse commonly have injuries on the upper extremities, head, and neck. Suspicious circumstances and injury patterns may be identified and are commonly present when victims of physical elder abuse present with purportedly accidental injuries.

2014-09-01

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.

Poison hemlock (Conium maculatum) is a plant that is poisonous for humans and animals. Accidental ingestion of the plant may result in central nervous system depression, respiratory failure, acute rhabdomyolysis, acute renal failure and even death. The main treatment of hemlock poisoning is supportive care. The case of a 6-year-old girl who was admitted to the emergency department with complaints of burning sensation in mouth, hypersalivation, tremor in hands and ataxia after ingestion of poison hemlock is presented here with clinical and laboratory features. In this case, we aim to report that accidental ingestion of plants resembling vegetables that are consumed daily can lead to serious complications and even death.

A screening tool to prioritize public health risk associated with accidental or deliberate release of chemicals into the atmosphere

PubMed Central

2013-01-01

The Chemical Events Working Group of the Global Health Security Initiative has developed a flexible screening tool for chemicals that present a risk when accidentally or deliberately released into the atmosphere. The tool is generic, semi-quantitative, independent of site, situation and scenario, encompasses all chemical hazards (toxicity, flammability and reactivity), and can be easily and quickly implemented by non-subject matter experts using freely available, authoritative information. Public health practitioners and planners can use the screening tool to assist them in directing their activities in each of the five stages of the disaster management cycle. PMID:23517410

The prevention and clinical diagnostics of maltreatment of children and adolescents represents a great challenge to all medical disciplines concerned; therefore, an interdisciplinary collaboration is indispensable. Medicolegal experts require specific radiological examination methods for the differentiation between accidental and non-accidental injuries, depending on the corresponding point in question. In addition, a clear and structured radiological appraisal of the findings is necessary. On the other hand, radiologists require an appropriate succinctly phrased question from the medicolegal expert. A close collaboration between radiologists and medicolegal experts is mandatory for a better recognition of cases of child abuse; therefore, the joint establishment of diagnostic standards and a comprehensive implementation is necessary.

Strangulation by Feeding Tube in a 23-Month-Old With Down Syndrome: Case Report and Review of Literature.

Ligature strangulation, although typically homicidal in nature, has been reported as accidental in both the pediatric and adult populations. The unique mode of accidental strangulation with a gastric feeding tube in a 23-month-old with Down syndrome is currently unreported in the literature and has prompted us to report this case and look into safety modifications that can be made to these common medical devices. Given the number of children with gastric feeding tubes and concern over this exact scenario brought up by parents, it is unusual that a similar case has not been reported.

The discovery of a dismembered corpse, especially that of a newborn, represents a significant challenge for forensic investigators. The cause of the dismemberment, be it natural, accidental, or criminal, must be determined. Another important question to distinguish between neonaticide and stillbirth is whether the infant was alive after birth. The present case - a dismembered infant corpse discovered in the washing at a commercial laundry - describes a forensic investigation which could avoid premature or wrong conclusions by identifying the corpse as a stillbirth that was accidentally disposed of in the laundry after an autopsy had been performed.

Clinical perspectives on osteogenesis imperfecta versus non-accidental injury.

PubMed

Pereira, Elaine Maria

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.

Ingested foreign body is an infrequent indication for emergency endoscopy in the adult gastroenterology practice. We describe the clinical features and endoscopic management of the first four cases of accidental ingestion of hijab pins by Muslim women in our unit, all presenting within a 12-month period. The pins were all successfully retrieved without any complications. In this report, we review published guidelines and the current literature, as well as discussing the approach (conservative vs proactive endoscopic retrieval) and timing of endoscopic treatment. The Muslim community may need to be alerted to the potential health hazard of hijab pins. PMID:24390968

Two patients with polycythemia vera received intravenously an accidental tenfold overdosage of radiophosphorus therapy (60 and 50 mCi 32P, respectively). In both patients, the occurrence of hemorrhagic complications 3 wk after the 32P medication led to detection of the error and referral to our hospital. Upon admission they showed an agranulocytosis, severe thrombocytopenia, and bone marrow aplasia. In both cases, spontaneous recovery of the hematopoiesis was observed from day 40 posttreatment onward. In one patient, a slow but ultimately complete normalization of blood counts and marrow morphology took place, whereas in the other, a mild thrombocytopenia persists. Nearly 5 yrmore » after the accidental overdosage, both patients are clinically well. Symptoms of polycythemia vera have not reappeared up to now. Attempts were made to evaluate the radiation dose absorbed by the bone marrow. In the first patient, the daily 32P excretion was determined from day 22 to day 60, whereas in the other patient a whole body count was performed on day 78 after administration. From these results, an approximate cumulative bone marrow dose of 10 Sv (1000 rem) could be calculated.« less

In-depth analysis of accidental oil spills from tankers in the context of global spill trends from all sources.

PubMed

Burgherr, Peter

2007-02-09

This study gives a global overview of accidental oil spills from all sources (> or =700t) for the period 1970-2004, followed by a detailed examination of trends in accidental tanker spills. The present analysis of the number and volume of tanker spills includes temporal and spatial spill trends, aspects of spill size distribution as well as trends of key factors (i.e., flag state, hull type, tanker age, accident cause and sensitivity of location). Results show that the total number and volume of tanker spills have significantly decreased since the 1970s, which is in contrast to increases in maritime transport of oil and to popular perceptions following recent catastrophic events. However, many spills still occur in ecologically sensitive locations because the major maritime transport routes often cross the boundaries of the Large Marine Ecosystems, but the substantially lower total spill volume is an important contribution to potentially reduce overall ecosystem impacts. In summary, the improvements achieved in the past decades have been the result of a set of initiatives and regulations implemented by governments, international organizations and the shipping industry.

To describe an emerging form of serious child abuse in combined homicide-suicide in Hong Kong. This is a retrospective hospital chart review in a regional hospital in Hong Kong from January to December 2000. Eight children, with a mean age of 7.8 years (range 0.5-11 years), from four families were admitted to hospital because of non-accidental exposure to carbon monoxide when their parents attempted suicide by burning charcoal. A 7-year-old boy died on arrival. His 5.6-year-old sister and another 6-month-old boy had cerebral hypoxia on admission. Hyperbaric oxygen therapy was used in both cases, with rapid improvement, although there were persistent neurological deficits in the girl. The other children in the present study were asymptomatic and none had delayed neurological sequelae. Concomitant use of sedatives was also detected in three of the surviving patients. Non-accidental poisoning with carbon monoxide appears to be a new means of child abuse with potentially serious consequences. Concomitant intoxication with psychotropic drugs is common in such cases. The reason for parents killing their own children under such circumstances was unclear, but a desire to exact revenge on an estranged partner was suggested.

ABSTRACT Aging of the patient population has led to increased occurrence of accidental falls in acute care settings. The aim of this study is to survey the annual occurrence of falls in a university hospital, and to examine procedures to prevent fall. A total of 49,059 inpatients were admitted to our hospital from April 2015 to March 2016. A fall assessment scale was developed to estimate the risk of fall at admission. Data on falls were obtained from the hospital incident reporting system. There were fall-related incidents in 826 patients (1.7%). Most falls occurred in hospital rooms (67%). Adverse events occurred in 101 patients who fell (12%) and were significantly more frequent in patients aged ≥80 years old and in those wearing slippers. The incidence of falls was also significantly higher in patients in the highest risk group. These results support the validity of the risk assessment scale for predicting accidental falls in an acute treatment setting. The findings also clarify the demographic and environmental factors and consequences associated with fall. These results of the study could provide important information for designing effective interventions to prevent fall in elderly patients. PMID:28878434

To explore the short-term impact of ambient PM(10) on daily non-accidental death, cardiovascular and respiratory death of residents in Beijing. Mortality data of residents in Beijing during 2006 to 2009 were obtained from public health surveillance and information service center of Chinese Center for Disease Control and Prevention, contemporaneous data of average daily air concentration of PM(10), SO(2), NO(2) were obtained from Beijing Environment Protection Bureau (year 2005 - 2006) and public website of Beijing environmental protection (year 2007 - 2009), respectively, contemporaneous meteorological data were obtained from china meteorological data sharing service system. Generalized addictive model (GAM) of time serial analysis was applied. In additional to the control of confounding factors such as long-term trend, day of the week effect, meteorological factors, lag effect and the effects of other atmospheric pollutants were also analyzed. During year 2006 to 2009, the number of average daily non-accidental death, respiratory disease caused death, cardiovascular and cerebrovascular diseases caused death among Beijing residents were 140.1, 15.0, 65.8, respectively;contemporaneous medians of average daily air concentration of PM(10), SO(2), NO(2) were 123.0, 26.0, 58.0 µg/m(3), respectively;contemporaneous average atmosphere pressure, temperature and relative humidity were 10.1 kPa, 13.5°C and 51.9%, respectively. An exposure-response relationship between exposure to ambient PM(10) and increased daily death number was found as every 10 µg/m(3) increase in daily average concentration of PM(10), there was a 0.1267% (95%CI: 0.0824% - 0.1710%) increase in daily non-accidental death of residents, 0.1365% (95%CI: 0.0010% - 0.2720%) increase in respiratory death and 0.1239% (95%CI: 0.0589% - 0.1889%) increase in cardiovascular death. Ambient PM(10) had greatest influence on daily non-accidental and cardiovascular death of the same day, while its greatest influence on respiratory death occurred 5 days later. The ambient PM(10) pollution increased daily non-accidental, respiratory disease caused, cardiovascular and cerebrovascular diseases caused deaths among residents in Beijing, and lag effect existed as for the effect of ambient PM(10) pollution on respiratory disease caused death.

Myer, GD, Quatman, CE, Khoury, J, Wall, EJ, and Hewett, TE. 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 < 0.05) with age: 8 to 13 > 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p < 0.05). Evaluation of only the nonaccidental injuries (n = 2, 565) showed that the oldest categories (19–22 and 23–30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p < 0.001). Two thirds of the injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to “dropping” and “pinching” in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p < 0.001). The study findings indicate that children have lower risk of resistance training-related joint 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

[Rehabilitation as component of falls prevention program in the elderly].

Zak, Marek; Melcher, Urszula

2002-01-01

Accidental falls tend to be anxiously perceived by a steadily increasing number of elderly persons as a definite symptom of ageing, instilling them with fear of becoming invariably care-dependent in the wake of having sustained a serious fall. Minimising the risk of accidental falls and complications resulting from them depends upon gaining a good insight into the accompanying circumstances, all with a view to establishing the nature of potential risks and developing a series of effective measures aimed at their prevention. Detailed reconstruction of the accompanying circumstances is a practical way of establishing all key risk factors and facilitates subsequent monitoring of patients' mobility, as well as effectively safeguards them against taking any undue risks. Since the observations made by the present authors and other investigators alike gave ample grounds to believe that rehabilitation constituted an essential component in any fall prevention programme, the impact of a specific rehabilitation regimen on the incidence of falls amongst the residents of STYRIA Municipal Nursing Home, Chorzów, was assessed with a view to establishing the pertinent correlations. The inclusion criteria required that a resident must have sustained at least one accidental fall in the period preceding the actual study (pursued in 1999-2000). Out of 61 residents 28 (aged 68-91) were eventually enrolled. The study focused principally upon assessing the risk of accidental falls and individual functional abilities. A three-month long rehabilitation programme embraced, e.g. individual counseling on the potential risk of falls, kinesitherapy and practical exercises in a safe change of posture. Comparative analysis was pursued with the aid of a non-parametric Wilcoxon test. The results confirmed the statistical significance of all parameters under investigation, which in turn gave ample grounds to believe that an appropriately designed rehabilitation programme might be effectively instrumental in fall prevention. This conclusion was further corroborated by the nursing reports, attesting to the perceptibly lesser frequency of accidental falls amongst the residents. There seems to be overall a substantial potential for gaining tangible benefits without the public health sector incurring undue financial burdens, whereas steady ageing of the country's population and the attendant increase of health care expenditure should prove an effective stimulus to launching comprehensive preventive schemes.

Accidental Predissociation: A Special Case of Photo-Induced Isotope Fractionation Effect and Possible Occurrence in Nature

NASA Astrophysics Data System (ADS)

Chakraborty, S.; Thiemens, M. H.

2009-12-01

Photo-Induced Isotope Fractionation Effects (PHIFE) are known to produce isotopic frac-tionation in some photo-dissociating molecules (1-2). The PHIFE formalism is based on the Born-Oppenheimer approximation and the Reflection Principle. The isotopic fractionation arises principally from the spectral shift induced by the small difference in zero point energy between isotopologues and the contraction of the wave function due to isotopic substitution, consequently, the associated isotopic fractionations depends on the reduced mass of the isotopically substi-tuted species. The PHIFE formalism is only applicable to the molecules which undergo direct photo-dissociation that possess continuous absorption spectra. Simple molecules (N2, O2, CO) however do not follow a direct dissociation pathway and dissociate through an indirect process termed predissociation, which occurs when the molecule is excited to a quasi-bound state energetically above the dissociation continuum. The PHIFE formalism is not applicable when the absorption spectra are discrete. The assumption that the lightest isotopologues are preferentially predissociated is only valid for restricted predissociation cases. There is a special case of predissociation known as ‘accidental predissociation’ (3), which takes place through an intermediate bound state in two steps (i) leakage to an intermediate bound state (coupled through spin orbit interaction) and, (ii) predissociation to a third quasi-bound state from the intermediate state. Line broadening at an accidental predissociation is a function of the magnitude of coupling matrix elements and the linewidths are strongly influenced by isotopic substitution (4). An anomalous isotopic effect in accidental predissociation was spectroscopically observed in CO (5), N2 (4) and BeH (6). We measured the isotopic fractionation for the first time in two accidental predissociating states of CO through VUV photodissociation using the 9.0.2 beamline at ALS (7-8). In light of these data, anomalous isotopic fractionations associated with accidental predissociation will be discussed for the CO and N2. These fractionations are important as VUV-photodissociation of CO and N2 have been invoked in solar nebula (self-shielding, (9-10)) to explain the observed iso-topic signatures in different solar system objects neglecting these isotope effects during photo-dissociation.

A longitudinal, retrospective and descriptive study about child abuse was carried out in the Hospitals of the Tlaxcala Secretariat of Health, Mexico. The information was obtained from hospitalized children's charts between January first and November 30, 1991. The charts included were those belonging to zero to 14 year old children with injuries, poisoning, and II-III degrees of malnutrition. Four child-abuse criteria were established: physical, sexual, non organic malnutrition and mixed (physical and non organic malnutrition). Two control groups were defined. Different patterns were observed between accidental and non accidental injuries, malnutrition and poisoning among the case and the control groups. The study provides useful information for the integral diagnosis of child abuse in hospitalized children.

The information encoded in the polarization of a single photon can be transferred to a remote location by two-channel continuous-variable quantum teleportation. However, the finite entanglement used in the teleportation causes random changes in photon number. If more than one photon appears in the output, the continuous-variable teleportation accidentally produces clones of the original input photon. In this paper, we derive the polarization statistics of the N-photon output components and show that they can be decomposed into an optimal cloning term and completely unpolarized noise. We find that the accidental cloning of the input photon is nearly optimal at experimentallymore » feasible squeezing levels, indicating that the loss of polarization information is partially compensated by the availability of clones.« less

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.

Wesselink, P R

2011-04-01

Accidental detection of an asymptomatic apical periodontitis raises the question whether this lesion should be treated or not. Arguments favouring treatment are that the inflammation may cause pain in the future, may enlarge or may negatively affect the host's resistance. Reasons for not treating may be that treatment weakens the tooth, may cause iatrogenic damage and that treatment is expensive and burdensome for the patient and does not lead in all cases to complete healing. Scientific evidence supporting either choice, whether treating the lesion or not, is lacking. In making such decisions, therefore, personal judgments by the patient and the dentist concerning the impact on the quality of life of the patient play an important role.

Numerous multiple trauma and surgical patients suffer from accidental hypothermia. While induced hypothermia is commonly used in elective cardiac surgery due to its protective effects, accidental hypothermia is associated with increased posttraumatic complications and even mortality in severely injured patients. This paper focuses on protective molecular mechanisms of hypothermia on apoptosis and the posttraumatic immune response. Although information regarding severe trauma is limited, there is evidence that induced hypothermia may have beneficial effects on the posttraumatic immune response as well as apoptosis in animal studies and certain clinical situations. However, more profound knowledge of mechanisms is necessary before randomized clinical trials in trauma patients can be initiated. PMID:22481864

During the 13-year period of 1973-1985, at least 329 deaths in Jordan resulted from poisoning by pesticides. Organophosphates were the major compounds incriminated in 93.6% of the cases. The annual mortality rate compared with that of other countries is relatively high, and was 5.97%, 17.35%, and 2.6% per 1 million people in 1973, 1979, and 1985, respectively. The annual mortality rates due to suicidal and accidental poisoning are 61% and 35.3%, respectively: 74% of the accidentally poisoned group are children less than 10 years, while 60.7% of the suicides are 15-24 years of age. To minimize such high mortality rates from pesticide poisoning, Jordan needs to adopt more protective measures by rigorous regulation.

Extracting the Essential Cartographic Functionality of Programs on the Web

2018-05-01

Following Aristotle, F. P. Brooks (1987) emphasizes the distinction between "essential difficulties" and "accidental difficulties" as a key challenge in software engineering. From the point of view of cartography, it would be desirable to identify the cartographic essence of a program, and subject it to additional scrutiny, while its accidental proper-ties, again from the point of view of cartography, are usually of lesser relevance to cartographic analysis. In this paper, two methods that facilitate extracting the cartographic essence of programs are presented: close reading of their source code, and the automated analysis of their runtime behavior. The advantages and shortcomings of both methods are discussed, followed by an outlook to future developments and potential applications.

Every pediatrician will be confronted with newborns oryoung infants with skin lesions in proximity of the vertebral column. It is important not to miss a spinal dysraphism because of the risk of meningeal infection or of the possible presence of a tethered cord. A practical algorithm is presented. Non-accidental injury in young infants and toddlers is not rare but difficult to detect. Bruises and fractures are highly suspicious for non-accidental injury and should trigger specific investigations. Emergency departments and hospitals are switching from hypotonic to isotonic solutions as maintenance infusions of children. They reduce the risk of hyponatremia without increasing that of hypernatremia, and they should be used preferentially in the majority of pediatric clinical settings.

Most ingested objects pass through the gastrointestinal tract (GIT) spontaneously, but approximately 10%-20% need to be removed endoscopically and 1% require surgery. This case reports a complication arising from the accidental loss of an archwire fragment during maxillary archwire placement. It describes the immediate and subsequent management, including the use of radiographs to track the passage of the fragment through the gastro-intestinal tract. This case stresses the vigilance that dentists must take to prevent inhalation or ingestion of foreign bodies and the consequences of time-delays when management decisions are needed.

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.

Temporary brittle bone disease: fractures in medical care.

PubMed

Paterson, Colin R

2009-12-01

Temporary brittle bone disease is the name given to a syndrome first reported in 1990, in which fractures occur in infants in the first year of life. The fractures include rib fractures and metaphyseal fractures which are mostly asymptomatic. The radiological features of this disorder mimic those often ascribed to typical non-accidental injury. The subject has been controversial, some authors suggesting that the disorder does not exist. This study reports five infants with typical features of temporary brittle bone disease in whom all or most of the fractures took place while in hospital. A non-accidental cause can be eliminated with some confidence, and these cases provide evidence in support of the existence of temporary brittle bone disease.

Non-accidental trauma in pediatric patients: a review of epidemiology, pathophysiology, diagnosis and treatment

Non-accidental trauma (NAT) is a leading cause of childhood traumatic injury and death in the United States. It is estimated that 1,400 children died from maltreatment in the United States in 2002 and abusive head trauma (AHT) accounted for 80% of these deaths. This review examines the epidemiology and risk factors for NAT as well as the general presentation and required medical work up of abused children. In addition, potential algorithms for recognizing cases of abuse are reviewed as well as outcomes in children with NAT and potential neurosurgical interventions which may be required. Finally, the evidence for seizure prophylaxis in this population is addressed. PMID:26835337

Loss-of-function mutations in the gene SCN5A can cause Brugada syndrome (BrS), which is an inherited form of idiopathic ventricular fibrillation. We report the case of a 46-year-old patient, with no previous medical history, who had ventricular fibrillation after accidental inhalation of gasoline vapors. His electrocardiogram (ECG) showed a typical type-1 BrS pattern that persisted after the acute event. Genetic investigations allowed the identification of a novel SCN5A mutation leading to a frame-shift and early termination of the channel protein. Biochemical and cellular electrophysiology experiments confirmed the loss-of-function of the mutant allele. The patient was implanted with a cardioverter/defibrillator.

Accidental sulfur mustard exposure: A case report.

The clinical progression following a sulfur mustard-induced skin exposure is well documented in the literature. Upon skin contact and a characteristic latency period, sulfur mustard (SM) causes erythema, blister formation and ulceration, which is associated with wound healing disorders that may require surgical treatment. Here, we present a case report of accidental exposure to SM in a laboratory setting which required surgical treatment of the skin. The case was illustrated at close intervals over a period of two years and underlines that exposure to SM has to be taken into account when typical clinical symptoms occur. Moreover skin grafts appear to be effective in SM-induced non healing skin ulcerations. Copyright © 2017 Elsevier B.V. All rights reserved.

Accidental low velocity atypical missile injury to the head.

Chattopadhyay, Saurabh

2008-12-01

Missile injuries on the head are mostly due to firearms. Atypical missiles may be encountered in case of shrapnel of bomb explosions but rarely because of stones. The present case is a rare case where a stone propelled by the pressure from the rear wheel of a speeding truck on the highway, struck the head of a 7-year-old girl resulting in fatality. Reconstruction of the incident on the basis of history and postmortem findings throws some light on the mechanism. The case is unique as it is the first reported case of an accidental missile injury to the head resulting in fatality without any direct human involvement for propulsion of the projectile.

76 FR 21299 - Emergency Planning and Notification; Emergency Planning and List of Extremely Hazardous...

Federal Register 2010, 2011, 2012, 2013, 2014

2011-04-15

...EPA is proposing to revise the manner by which the regulated community would apply the threshold planning quantities (TPQs) for those extremely hazardous substances (EHSs) that are non-reactive solid chemicals in solution form. Specifically, facilities with a solid EHS in solution would be subject to the Emergency Planning requirements if the amount of the solid chemical on-site, when multiplied by 0.2, equaled or exceeded the lower published TPQ, based on data that shows less potential for the solid chemical in solution to remain airborne in the event of an accidental release. Previously, EPA assumed that 100% of the chemical could become airborne in the event of an accidental release.

The elemental composition of a sample at nanometer scale is determined by measurement of the characteristic energy of Auger electrons, emitted in coincidence with incoming primary electrons from a microbeam in a scanning transmission electron microscope (STEM). Single electrons are detected with position sensitive detectors, consisting of MicroChannel Plates (MCP) and MultiStrip Anodes (MSA), one for the energy of the Auger electrons (Auger-detector) and one for the energy loss of primary electrons (EELS-detector). The MSAs are sensed with LeCroy 2735DC preamplifiers. The fast readout is based on LeCroy's PCOS III system. On the detection of a coincidence (Event) energy data of Auger and EELS are combined with timing data to an Event word. Event words are stored in list mode in a VME memory module. Blocks of Event words are scanned by transputers in VME and two-dimensional energy histograms are filled using the timing information to obtain a maximal true/accidental ratio. The resulting histograms are stored on disk of a PC-386, which also controls data taking. The system is designed to handle 10 5 Events per second, 90% of which are accidental. In the histograms the "true" to "accidental" ratio will be 5. The dead time is 15%.

To investigate the parental perspectives of being confronted with an unforeseen fetal sex chromosomal aneuploidy (SCA), in light of the fact that this accidental finding is avoidable by rapid aneuploidy detection (RAD). Exploratory qualitative interview study. We conducted 16 semi-structured interviews with parents who decided to continue pregnancy after the unforeseen finding of a fetal SCA. The communication of the unforeseen finding of SCA; the informed decision-making process concerning the pregnancy follow-up and the child and its future were the extracted themes. Parents were not prepared to accidental findings in routine prenatal diagnostics. All started an unguided search on the Internet. It is not at all clear whether parents have preference for an RAD test with X and Y probes Parents were satisfied with the post-test professional information they received to make an informed decision, whereas after birth questions still remained to be answered. Parents' perspectives may serve as major contributors to research on the question whether or not the X and Y probes should be standard included for purposes of RAD. The fact that RAD has the possibility to avoid accidental findings of SCAs, brings up the question whether any benefits outweigh the potential harms. Copyright © 2011 John Wiley & Sons, Ltd.

From evolutionary advantage to disease agents: forensic re-evaluation of host-microbe interactions and pathogenicity

2016-01-01

As the “human microbiome era” continues, there is an increasing awareness of our resident microbiota and its indispensable role in our increased fitness as holobionts. However, the host-microbe relationship is not so clearly defined for some human symbionts. Here we discuss examples of “accidental pathogens”, meaning previously non-pathogenic and/or environmental microbes thought to have inadvertently experienced an evolutionary shift towards pathogenicity. For instance, symbionts such as Helicobacter pylori and JC Polyomavirus have been shown to accompany humans since prehistoric times and are still abundant in extant populations as part of the microbiome. And yet, the relationship between a subgroup of these microbes and their human hosts seems to have changed with time, and they have recently gained notoriety as gastrointestinal and neuropathogens, respectively. On the other hand, environmental microbes such as Legionella spp. have recently experienced a shift in host range and are now a major problem in industrialized countries as a result of artificial ecosystems. Other variables involved in this accidental phenomenon could be the apparent change or reduction in the diversity of human-associated microbiota because of modern medicine and lifestyles. All of this could result in an increased prevalence of “accidental pathogens” in the form of emerging pathogens. PMID:28155809

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 (p<0.001) higher. The majority suffered from polytrauma. Multiple 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.

Communication: Effect of accidental mode degeneracy on Raman intensity in 2D materials: Hybrid functional study of bilayer phosphorene

Sun, Yi-Yang; Zhang, Shengbai

2016-07-14

Bulk black phosphorus has two optical phonon modes labeled as A{sub g}{sup 2} and B{sub 2u}, respectively, that are nearly degenerate in frequency. However, density functional theory calculations using local or semi-local functionals cannot reproduce this degeneracy. Here, we propose a hybrid functional approach aided by van der Waals (vdW) force fields, which can accurately describe the lattice dynamic and electronic properties of both bulk and few-layer black phosphorus (phosphorene). Using this approach we show that in bilayer phosphorene, the two Raman modes derived from the B{sub 2u} and A{sub g}{sup 2} modes could exhibit strong resonance as a resultmore » of the accidental degeneracy so that both modes could be observed in Raman experiment. Without the mode degeneracy, however, the Raman intensity of the B{sub 2u}-derived mode would be too weak to be observed. We further show that the accidental degeneracy is correlated to the applied strain, which enables Raman spectroscopy to be a powerful tool for characterizing built-in strains in 2D materials, e.g., due to the interaction with substrates, which has emerged as an important issue in vdW epitaxy.« less

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.

Chronic or accidental exposure of oysters to norovirus: is there any difference in contamination?

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.

This study investigates tourist mortality at Lake Powell over a 46-year period. To date no comprehensive long-term investigation examining the relationship between the lake environment and tourist mortality exists. A retrospective study was conducted of all tourist fatalities between 1959 and 2005. There were 351 fatal incidents resulting in 386 deaths between 1959 and 2005. Over the 46-year period, the average number of fatalities was 8.4 (±5.26) per year. Out of all fatalities, 282 were classified as accidental, 80 were classified as natural deaths, 13 were suicides and 5 were classified as homicides. Males accounted for 80% of fatalities and tourists aged 20-29 years and 10-19 years accounted for 36% of all fatalities. The highest number of fatalities was recorded in July (74), May (64), August (63) and June (59). Out of all accidental deaths, boating (29%) and swimming (22%) were the most common pre-death activities. High winds capsizing boats and carbon monoxide poisoning from boat engines were common factors contributing to 31 boating fatalities. Fatigue and exhaustion contributed to 22 swimming deaths. Recreational boating and swimming account for over half of all accidental deaths. Tourists visiting Lake Powell for recreational purposes should be informed of the risks associated with the lake environment.

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

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.

A study of accidental non-commercial aircraft fatalities was performed on the case files of the Office of the Medical Examiner of Metropolitan Dade County in Miami, FL, U.S.A., between the years 1977 through 1983. A total of 57 cases were collected and analyzed as to the age of the victim, the race and sex of the victim, the cause of death, the blood alcohol content at autopsy, the drugs detected at autopsy, the type of aircraft, the occupant role, the risk factor responsible for the crash, the time of the fatality, and the nature of usage of the aircraft. Essentially, these 57 cases comprised 1.2% of the non-vehicular accidental fatalities during the period. The age of distribution is relatively evenly distributed from age 16 to 65 years with white males predominating. Multiple injuries were the most common cause of death although conflagration injuries (e.g., smoke inhalation, burns) were frequent. The victims were sober and free of drugs in the majority of cases. Most fatalities occurred in a single engine plane with the victim, the pilot, flying for private reasons in the afternoon or evening hours. The most common identifiable risk factor was human error (e.g., judgement), rather than mechanical or plane failure.

Bolt gun or slaughterer's guns are used in meat industry for "humane killing" of animals. Injuries caused by bolt gun are rare, reported exclusively from central European countries. We report a case of 28 year old male, who accidentally shot himself with a bolt gun to his right thigh. A 28 years old male presented to our Accident and Emergency department after accidental injury to his right thigh with bolt gun. He had an entry wound measuring 2 cm in length and 1 cm in breadth over anterior aspect of lower one third of thigh at lower and sustained Grade II compound fracture of right femur shaft at distal one third. The wound was treated with multiple debridements, negative pressure wound therapy and intravenous antibiotics based on culture and sensitivity. Bolt gun or slaughterer's guns are weapons used in meat industry for slaughtering animals. Wounds inflicted by bolt guns have specific morphological feature, distinctive from wounds made by other kinds of hand firearms. Most of the time wound will be infected at presentation. Lesions caused by these weapons are likely to have a more serious character than is to be expected from the size of the entrance wound. The mainstay of treatment is liberal wound exploration, multiple debridement's and intra venous antibiotics based on culture reports to treat infection and prevent morbidity.

The need for a less conservative, but reliable risk assessment of accidental tritium releases is emphasized in the present debate on the nuclear energy future. The development of a standard conceptual model for accidental tritium releases must be based on the process level analysis and the appropriate experimental database. Tritium transfer from atmosphere to plants and the subsequent conversion into organically bound tritium (OBT) strongly depends on the plant characteristics, seasons, and meteorological conditions, which have a large variability. The present study presents an overview of the relevant experimental data for the short term exposure, including the unpublished information, also. Plenty of experimental data is provided for wheat, rice, and soybean and some for potato, bean, cherry tomato, radish, cabbage, and tangerine as well. Tritiated water (HTO) uptake by plants during the daytime and nighttime has an important role in further OBT synthesis. OBT formation in crops depends on the development stage, length, and condition of exposure. OBT translocation to the edible plant parts differs between the crops analyzed. OBT formation during the nighttime is comparable with that during the daytime. The present study is a preliminary step for the development of a robust model of crop contamination after an HTO accidental release. Copyright © 2012 Elsevier Ltd. All rights reserved.

Hypothyroidism is one of the common causes of the secondary hypercholesterolemia. The prevalence of hypothyroidism in the general population is estimated to be as high as about 1.5%. Frequency of the hypothyroidism in patients with hyperlipidemia is high, and can be observed in 4.2-10% in different populations. Most commonly, there is no need to treat the hypothyroid patients with the hypolipidemic drugs. Substitution treatment with the thyroid hormones usually results in either normalization or significant decreasing of the lipid levels. Hypothyroidism with symptoms of involvement of skeletal muscles is referred as to hypothyroid myopathy in English literature, and can be present in 30-80% patients with deficiency of the thyroid hormones. Hypothyroidism is a risk factor of developing of toxic injury of muscles, what is thought to be related to hypolipidemic drug intake. We report a case of a patient with undiagnosed hypothyroidism with muscle involvement manifestation, who was treated with fenofibrate due to accidentally diagnosed hypercholesterolemia. Hypolipidemic management resulted in rapid exacerbation of previously moderate myopathy. High concentrations of muscle enzymes and moderate increasing of creatinine concentration were detected. Improvement was observed after discontinuation of fenofibrate administration, but muscle symptoms and elevation of muscle enzymes and creatinine persisted. After administration of levothyroxin, muscle weakness and laboratory abnormalities were observed no longer. After several months of follow-up we believe that treatment with fenofibrate in our patient was complicated with muscle tissue damage and exacerbated symptoms of myopathy originally related to decompensated hypothyroidism.

Poisoning among children and youths in the northeastern part of Poland accounted for 25% of the total number of patients admitted to the Hospital Emergency Department of the Paediatric University Hospital of Białystok. We hypothesise that the epidemiology of poisoned paediatric patients admitted is related to increase in 'designer drugs' (mainly amphetamine- and ecstasy-like psychostimulants, hallucinogens and synthetic cannabinoids ('spice') intake, which became popular 5 years ago in our country. A retrospective chart review of medical records of 489 patients admitted due to poisoning in the 5-year period (2006-2010). The data included: age, sex, place of residence, nature of the substance, causes of poisoning, former use of psychoactive stimulants, accompanying self-mutilation and injuries and length of hospitalisation. Categorical variables were expressed as percentages, and continuous variables as mean and SD. The data were collected in a Microsoft Excel database. Statistical analysis was performed using the Statistical Programme for Social Sciences. Out of 2176 hospitalised children, 489 were admitted because of poisoning. Out of these, 244 (49.9%) were hospitalised due to intoxication by alcohol. Only eight children used designer drugs. The mean age of all patients in our group was 12.86±5.04 years, of which 52.4% were male. Poisoning was intentional in 75.5%, and accidental in 24.5% of cases. Appearance of 'designer drugs' had no significant impact on the number and epidemiology of poisonings in our group.

An 18 year old girl was admitted with progressive painful dysphagia and a severe hemorrhagic endoscopically impassable esophagitis. She reported to have consumed an unknown liquid from a small flask on a party three weeks ago. Later on, this liquid was identified as a party- and sex-drug known as "Poppers", designed to be consumed by sniffing. On admission she had difficulties in swallowing liquids and even saliva. She had lost 8 kg of weight during the last 3 weeks. Clinical examination revealed tachycardia, a moderate tenderness in the epigastrium and sparse bowel sounds. Investigation and treatment: On endoscopy, there was a severe corrosion injury of the esophagus with a consecutive stenosis at 40 cm ab ore. The stenosis could not be passed even with a 4.9 mm instrument. After initial placement of a feeding tube the stenosis was dilated with Savary-Bougies. In the following years, the patient suffered from recurrent stenosis due to excessive scar formation. Repeated treatment with longitudinal incisions by needle knife and steroid injections improved symptoms to a tolerable degree. 5 years after ingestion, the patient still carries a long segment esophageal scarring with mild to moderate stenosis. The party drug Poppers is an organic nitrogen compound that has increasingly come into use over the past years. It may cause severe and life threatening esophageal chemical burn injury. Symptoms of painful dysphagia after intake of an "unknown" liquid party drug should raise the suspicion of an accidental oral ingestion of Poppers. © Georg Thieme Verlag KG Stuttgart · New York.

The Impact of Improving Suicide Death Classification in South Korea: A Comparison with Japan and Hong Kong

2015-01-01

Introduction The suicide rate of South Korea has increased dramatically during the past decades, as opposed to steadily decreasing trends in Japan and Hong Kong. Although the recent increase of suicide in South Korea may be related to changing socioeconomic conditions and other contextual factors, it may also reflect, in part, a reduction of misidentified suicide cases due to improving classification of manner of death. Method We compared the annual proportional change of suicide, undetermined death, and accidental death from South Korea with those of Japan and Hong Kong from 1992 to 2011; a greater proportional change of the manner-of-death categories during the period is indicative of a relatively less stable registration and hence a greater potential for misclassification bias on reported suicide trends. Subgroup analyses stratifying the deaths by methods were also conducted. To estimate the impact, the age-standardized rates of these three death categories in each site were calculated. Results We found that, during the 20-year observation period, the proportional change of suicide, undetermined death, and accidental death in South Korea was significantly greater than Japan and Hong Kong. Similar observations were made in subgroup analyses. While death rates of the three manners in Japan and Hong Kong generally moved in a parallel fashion, the increase of suicide in South Korea occurred concomitantly with a significant reduction of its accidental death rate. 43% of the increase in suicides could be attributed to the decrease in accidental deaths, while 57% of the increase could be due to fundamental causes. Conclusion Our data suggest that, during the mid-1990s and after, the increasing burden of suicide in South Korea initially was masked, in part, by misclassification. Thus, the later apparently rapid increase of suicides reflected steadily improving classification of manner of death, as well as a more fundamental increase in the suicide rate. PMID:25992879

Introduction While geriatric trauma patients have begun to receive increased attention, little research has investigated assault-related injuries among older adults. Our goal was to describe characteristics, treatment, and outcomes of geriatric assault victims and compare them to geriatric victims of and younger accidental injury assault victims. Patients and Methods We conducted a retrospective analysis of the 2008–2012 National Trauma Data Bank. We identified cases of assault-related injury admitted to trauma centers in patients aged ≥60 using the variable “intent of injury.” Results 3,564 victims of assault-related injury in patients aged ≥60 were identified and compared to 200,194 geriatric accident victims and 94,511 assault victims aged 18–59. Geriatric assault victims were more likely than geriatric accidental injury victims to be male (81% vs. 47%) and were younger than accidental injury victims (67±7 vs. 74±9 years). More geriatric assault victims tested positive for alcohol or drugs than geriatric accident victims (30% vs. 9%). Injuries for geriatric assault victims were more commonly on the face (30%) and head (27%) than for either comparison group. Traumatic brain injury (34%) and penetrating injury (32%) occurred commonly. The median injury severity score (ISS) for geriatric assault victims was 9, with 34% having severe trauma (ISS≥16). Median length of stay was 3 days, 39% required ICU care, and in-hospital mortality was 8%. Injury severity was greater in geriatric than younger adult assault victims, and, even when controlling for injury severity, in-hospital mortality, length of hospitalization, and need for ICU-level care were significantly higher in older adults. Conclusions Geriatric assault victims have characteristics and injury patterns that differ significantly from geriatric accidental injury victims. These victims also have more severe injuries, higher mortality, and poorer outcomes than younger victims. Additional research is necessary to improve identification of these victims and inform treatment strategies for this unique population. PMID:27720184

Injuries for geriatric assault victims were more commonly on the face (30%) and head (27%) than for either comparison group. Traumatic brain injury (34%) and penetrating injury (32%) occurred commonly. The median injury severity score (ISS) for geriatric assault victims was 9, with 34% having severe trauma (ISS≥16). Median length of stay was 3 days, 39% required ICU care, and in-hospital mortality was 8%. Injury severity was greater in geriatric than younger adult assault victims, and, even when controlling for injury severity, in-hospital mortality, length of hospitalization, and need for ICU-level care were significantly higher in older adults. Geriatric assault victims have characteristics and injury patterns that differ significantly from geriatric accidental injury victims. These victims also have more severe injuries, higher mortality, and poorer outcomes than younger victims. Additional research is necessary to improve identification of these victims and inform treatment strategies for this unique population. Copyright © 2016 Elsevier Ltd. All rights reserved.

Although there is concern that food allergy reactions may negatively affect the natural history of food allergy, the impact of reactions on food-specific IgE (sIgE) levels or skin prick test (SPT) wheal size is unknown. To measure the effects of allergic reactions on SPT wheal size and sIgE concentrations to milk, egg, and peanut. Participants included 512 infants with likely milk or egg allergy enrolled in a multicenter observational study. Changes in sIgE level and SPT wheal size to milk, egg, and peanut were measured before and after oral food challenge (OFC) or accidental exposure for 377 participants. The median age of the cohort at the time of analysis was 8.5 years (67% males). There were no statistically significant changes in sIgE level or SPT wheal size after positive OFC to milk, egg, or peanut (n = 20-27 for each food). Change in sIgE level and SPT wheal size was measured after 446 and 453 accidental exposure reactions, respectively. The median change in sIgE level was a decrease of 0.33 kU(A)/L (P < .01) after milk and 0.34 kU(A)/L (P < .01) after egg reactions, but no other statistically significant changes in sIgE level or SPT wheal size were observed for milk, egg, or peanut. When we limited the analysis to only those participants who had diagnostic testing done within 6 months of an accidental exposure reaction, we found that peanut SPT wheal size increased by 1.75 mm (P < .01), but a significant increase was not noted when all participants with testing done within 12 months were considered. The results suggest that reactions from OFCs and accidental exposure are not associated with increases in sensitization among children allergic to milk, egg, or peanut.

Excess mortality during heat waves and cold spells in Moscow, Russia.

PubMed

Revich, B; Shaposhnikov, D

2008-10-01

To estimate excess mortality during heat waves and cold spells, and to identify vulnerable population groups by age and cause of death. Daily mortality in Moscow, Russia from all non-accidental, cardiovascular and respiratory causes between January 2000 and February 2006 was analysed. Mortality and displaced mortality during cold spells and heat waves were estimated using independent samples t tests. Cumulative excess non-accidental mortality during the 2001 heat wave was 33% (95% CI 20% to 46%), or approximately 1200 additional deaths, with short-term displaced mortality contributing about 10% of these. Mortality from coronary heart disease increased by 32% (95% CI 16% to 48%), cerebrovascular mortality by 51% (95% CI 29% to 73%) and respiratory mortality by 80% (95% CI 57% to 101%). In the 75+ age group, corresponding mortality increments were consistently higher except respiratory deaths. An estimated 560 extra deaths were observed during the three heat waves of 2002, when non-accidental mortality increased by 8.5%, 7.8% and 6.1%, respectively. About 40% of these deaths were brought forward by only a few days, bringing net mortality change down to 3.2% (95% CI 0.8% to 5.5%). The cumulative effects of the two cold spells in 2006 on mortality were significant only in the 75+ age group, for which average daily mortality from all non-accidental causes increased by 9.9% (95% CI 8.0% to 12%) and 8.9% (95% CI 6.7% to 11%), resulting in 370 extra deaths; there were also significant increases in coronary disease mortality and cerebrovascular mortality. This study confirms that daily mortality in Moscow increases during heat waves and cold spells. A considerable proportion of excess deaths during heat waves occur a short time earlier than they would otherwise have done. Harvesting, or short-term mortality displacement, may be less significant for longer periods of sustained heat stress.

The impact of improving suicide death classification in South Korea: a comparison with Japan and Hong Kong.

2015-01-01

The suicide rate of South Korea has increased dramatically during the past decades, as opposed to steadily decreasing trends in Japan and Hong Kong. Although the recent increase of suicide in South Korea may be related to changing socioeconomic conditions and other contextual factors, it may also reflect, in part, a reduction of misidentified suicide cases due to improving classification of manner of death. We compared the annual proportional change of suicide, undetermined death, and accidental death from South Korea with those of Japan and Hong Kong from 1992 to 2011; a greater proportional change of the manner-of-death categories during the period is indicative of a relatively less stable registration and hence a greater potential for misclassification bias on reported suicide trends. Subgroup analyses stratifying the deaths by methods were also conducted. To estimate the impact, the age-standardized rates of these three death categories in each site were calculated. We found that, during the 20-year observation period, the proportional change of suicide, undetermined death, and accidental death in South Korea was significantly greater than Japan and Hong Kong. Similar observations were made in subgroup analyses. While death rates of the three manners in Japan and Hong Kong generally moved in a parallel fashion, the increase of suicide in South Korea occurred concomitantly with a significant reduction of its accidental death rate. 43% of the increase in suicides could be attributed to the decrease in accidental deaths, while 57% of the increase could be due to fundamental causes. Our data suggest that, during the mid-1990s and after, the increasing burden of suicide in South Korea initially was masked, in part, by misclassification. Thus, the later apparently rapid increase of suicides reflected steadily improving classification of manner of death, as well as a more fundamental increase in the suicide rate.

Traumatic Penile Injury: From Circumcision Injury to Penile Amputation

PubMed Central

Park, Jae Young; Song, Yun Seob

2014-01-01

The treatment of external genitalia trauma is diverse according to the nature of trauma and injured anatomic site. The classification of trauma is important to establish a strategy of treatment; however, to date there has been less effort to make a classification for trauma of external genitalia. The classification of external trauma in male could be established by the nature of injury mechanism or anatomic site: accidental versus self-mutilation injury and penis versus penis plus scrotum or perineum. Accidental injury covers large portion of external genitalia trauma because of high prevalence and severity of this disease. The aim of this study is to summarize the mechanism and treatment of the traumatic injury of penis. This study is the first review describing the issue. PMID:25250318

Forecasting Spanish natural life expectancy.

Guillen, Montserrat; Vidiella-i-Anguera, Antoni

2005-10-01

Knowledge of trends in life expectancy is of major importance for policy planning. It is also a key indicator for assessing future development of life insurance products, substantiality of existing retirement schemes, and long-term care for the elderly. This article examines the feasibility of decomposing age-gender-specific accidental and natural mortality rates. We study this decomposition by using the Lee and Carter model. In particular, we fit the Poisson log-bilinear version of this model proposed by Wilmoth and Brouhns et al. to historical (1975-1998) Spanish mortality rates. In addition, by using the model introduced by Wilmoth and Valkonen we analyze mortality-gender differentials for accidental and natural rates. We present aggregated life expectancy forecasts compared with those constructed using nondecomposed mortality rates.

The pain relief capabilities of methyl salicylate are well established and a multitude of over-the-counter products populate pharmacy shelves. Over-application of the topical preparation containing the drug, or its accidental ingestion, invariably result in salicylate poisoning and in severe cases can be fatal. The drug has been a regular feature of the US National Poison Database Survey over the past decade and continues to pose a risk to children and adults alike. The aim of the review has been to cast a spotlight on the drug and assess why its use remains problematic, how technology could offer more efficacious delivery regimes, and minimise the possibility of accidental or intentional misuse.

It is well known that hydrogen peroxide ingestion can cause gas embolism. To report a case illustrating that the definitive, most effective treatment for gas embolism is hyperbaric oxygen therapy. We present a case of a woman who presented to the Emergency Department with acute abdominal pain after an accidental ingestion of concentrated hydrogen peroxide. Complete recovery from her symptoms occurred quickly with hyperbaric oxygen therapy. This is a case report of the successful use of hyperbaric oxygen therapy to treat portal venous gas embolism caused by hydrogen peroxide ingestion. Hyperbaric oxygen therapy can be considered for the treatment of symptomatic hydrogen peroxide ingestion. Copyright © 2012 Elsevier Inc. All rights reserved.

Drug use and accidental falls in an intermediate care facility.

PubMed

Sobel, K G; McCart, G M

1983-01-01

The relationship between nonenvironment-caused falls and drug use was evaluated in an intermediate care facility over a 14-month period. The medical problems and selected drug use of 45 patients who had fallen were retrospectively compared with those of a matched control population of 30 patients who had not fallen during this same period. Antihypertensives, diuretics, tranquilizers, sedative/hypnotics, antidepressants, and antianginal agents were reviewed for all patients. The use of diuretics, specifically furosemide, and sedative/hypnotics was significantly greater in the population who had fallen. Observations of dizziness, confusion, insomnia, and ataxia were recorded more frequently in that group, as well. Closer monitoring of medications, especially in specific drug classes, may help prevent accidental falls in this type of institution.

The simultaneous death of seven people due to the detonation of an antipersonnel landmine at the land borders of the European Union during peacetime.

PubMed

Pavlidis, Pavlos; Karakasi, Valeria

2015-01-01

This incident concerns the simultaneous death of seven people as a result of the accidental triggering of an antipersonnel landmine during peacetime. The victims were illegal migrants who attempted to cross the Greek-Turkish border zone and accidentally entered a demarcated minefield. This incident is presented because of its rarity and highlights the devastating consequences of the residual mines on the European Union eastern frontiers in peacetime. It also showcases the difficulties and risks that arise during the identification process in illegal migration issues. The victims' positions at the moment of explosion are indicated by the detailed forensic examination and comparison of the injuries' anatomical dispersion and their severity.

Deaths from electricity.

1984-03-14

This paper reviews the circumstances of 95 fatalities from electrical injuries. Eighty-nine were accidental, four were suicides and two occurred during autoerotic electrical stimulation. Forty-nine of the accidental fatalities occurred at work, Twenty-eight in the home and twelve in the course of outside recreational activities. In many accidents the circumstances were distressingly similar and included: (1) Contact with overhead distribution lines by a length of conductor such as a yacht mast or crane. (2) Faulty wiring or electrical repairs performed by unqualified people. (3) Badly deteriorated cords, plugs and occasionally appliances. (4) Failure to use isolating transformers when indicated. Deaths involving children are a particular cause of concern. Nine fatalites involved children under the age of five years who contacted inadequately protected wires.

Gap structure in Fe-based superconductors with accidental nodes: The role of hybridization

NASA Astrophysics Data System (ADS)

Hinojosa, Alberto; Chubukov, Andrey V.

2015-06-01

We study the effects of hybridization between the two electron pockets in Fe-based superconductors with s -wave gap with accidental nodes. We argue that hybridization reconstructs the Fermi surfaces and also induces an additional interpocket pairing component. We analyze how these two effects modify the gap structure by tracing the position of the nodal points of the energy dispersions in the superconducting state. We find three possible outcomes. In the first, the nodes simply shift their positions in the Brillouin zone; in the second, the nodes merge and disappear, in which case the gap function has either equal or opposite signs on the electron pockets; in the third, a new set of nodal points emerges, doubling the original number of nodes.

Non-accidental salt poisoning.

Meadow, R

1993-01-01

The clinical features of 12 children who incurred non-accidental salt poisoning are reported. The children usually presented to hospital in the first six months of life with unexplained hypernatraemia and associated illness. Most of the children suffered repetitive poisoning before detection. The perpetrator was believed to the mother for 10 children, the father for one, and either parent for one. Four children had serum sodium concentrations above 200 mmol/l. Seven children had incurred other fabricated illness, drug ingestion, physical abuse, or failure to thrive/neglect. Two children died; the other 10 remained healthy in alternative care. Features are described that should lead to earlier detection of salt poisoning; the importance of checking urine sodium excretion, whenever hypernatraemia occurs, is stressed. PMID:8503665

Firearm-related deaths in Brescia (Northern Italy) between 1994 and 2006: a retrospective study.

2009-08-01

This retrospective study analyzes post-mortem examination data of 164 firearm-related casualties recorded by the Brescia, Italy Institute of Forensic Medicine between the years 1994 and 2006. The following variables were considered: year, month and day of death, gender and age of the victim, manner of death (homicide, suicide, accidental), type of weapon used, anatomical site and number of wounds, scene of death, and, whenever requested by the local District Attorney's Office, results of the toxicological examinations conducted on the corpses of the deceased. In the County of Brescia, Italy, the 2006 firearm-related mortality rate amounted to 0.84 per 100,000 residents, with an average of 12.6 cases per year. The most common manner of death was suicide (60.4%), followed by homicide (35.9%) and accidental death (3.7%). Most victims were male, with an average age of 47.2 in cases of suicide, 37.9 in cases of homicide, and 47.5 in cases of accidental death. Considering all of the death manners contemplated in this study, the weapon types most frequently resorted to were single-action, short-barrelled guns, followed by multiple-action, long-barrelled ones. In cases of suicide, entry wounds were primarily situated on the head (right temple) and chest (precordium), while in cases of homicide no conclusions could be drawn as to the entry wounds' predominant location.

To identify clinical signs associated with and outcome of human exposure to Micotil 300 (tilmicosin injection). Retrospective case series. Reports of 3,168 human exposures to Micotil 300. Reports of human exposure to Micotil 300 submitted to the Elanco Animal Health Pharmacovigilance Unit between March 1992 and March 2005 were reviewed. At least 1 clinical sign was described in 1,404 (44%) reports, whereas the remaining 1,764 (56%) exposures were presumably asymptomatic. Eighty percent of exposures involved males; mean age was 38 years. Sixty-one percent of exposures were a result of accidental injection, with injection site pain, bleeding, swelling, or inflammation being the most common signs, followed by nausea, tachycardia, dizziness, anxiety, an abnormal taste, headache, lightheadedness, limb pain, paresthesia, chest pain, and soreness. Only 156 (5%) reports involved serious adverse effects (ie, tachycardia, bradycardia, hypertension, hypotension, heart disorder, chest pain, tachypnea, or death). There were reports of 13 deaths following tilmicosin exposure, but only 2 of those deaths were related to accidental exposure. Time to onset of clinical signs was < or = 60 minutes in 63 of the 156 (40%) reports involving serious adverse effects. Results suggest that the overall risk of accidental human exposure to tilmicosin resulting in serious adverse effects is low (approx 2 people for every 1 million doses administered). Nevertheless, safe handling and proper use should be emphasized.

The art and science of low-energy applications in medicine: pathology perspectives

NASA Astrophysics Data System (ADS)

Thomsen, Sharon L.

2011-03-01

Applications of low energy non-ionizing irradiation result in non-lethal and lethal effects in cells, tissues and intact individuals. The effects of these applications depend on the physical parameters of the applied energies, the mechanisms of interaction of these energies on the target and the biologic status of the target. Recently, cell death has been found not to be a random accident of situation or age but a range of complicated physiological responses to various extrinsic and intrinsic events some of which are genetically programmed and/ or physiologically regulated. Therefore, cell death has been classified into three general groups: 1) Programmed cell death including apoptosis and necroptosis, cornefication and autophagy; 2) Accidental (traumatic) cell death due to the direct, immediate effects of the lethal event and 3) Necrotic cell death which is, by default, all cell death not associated with programmed or accidental cell death. Lethal low energy non-ionizing application biologic effects involve mechanisms of all three groups as compared to high energy applications that predominantly involve the mechanisms of accidental cell death. Currently, the mechanisms of all these modes of cell death are being vigorously investigated. As research and development of new low energy applications continues, the need to understand the mechanisms of cell death that they produce will be critical to the rational creation of safe, yet effective instruments.

In all places where engineered Nanoparticles (ENPs) are produced, used or handled, adequate workplace safety precautions should be implemented due to the protection of workers and the surrounding environment. Any possible accidental release of ENPs should be evaluated. Thereby detected potential risks have to be eliminated as far as possible. An implemented reasonable safety culture in each ENP-related company will help to meet this challenge. Different infrastructures and workplace design can help to reduce the risk of an accidentally contact of the workers with ENPs: Transferable examples will be shown from the semiconductor and life-science Industry. These systems like clean rooms, glove boxes, fume cupboards, filter and suction systems and other restricted area barrier access systems (RABS) are mainly being developed to protect sensitive products, but they can also be used to protect working personnel. Clean environments regarding airborne particulate contaminations can be classified according to ISO 14644-1. A short insight into this ISO-classification will be given. But overall, a simple and reasonable workplace and workflow organization will reduce the risk of an accidental release of ENPs largely. This may lead to a therefore necessary adaption of existing workflow patterns. The workers have to get aware about the potential risks! This can be done with appropriate education materials, leaflets, posters and brochures. These are some of the later outcomes from the NanoDevice dissemination and handbook work package.

Loss of cabin pressurization in U.S. Naval aircraft: 1969-90.

PubMed

Bason, R; Yacavone, D W

1992-05-01

During the 22-year period from 1 January 1969 to 31 December 1990, there were 205 reported cases of loss of cabin pressure in US Naval aircraft; 21 were crew-initiated and 184 were deemed accidental. The ambient altitudes varied from 10,000 ft (3048 m) to 40,000 ft. (12192 m). The most common reason for crew-initiated decompression was to clear smoke and fumes from the cockpit/cabin (95%). The most common cause for accidental loss of cabin pressure was mechanical (73.37%), with aircraft structural damage accounting for the remaining 26.63%. Serious physiological problems included 1 pneumothorax, 11 cases of Type I decompression sickness, 23 cases of mild to moderate hypoxia with no loss of consciousness, 18 cases of hypoxia with loss of consciousness, and 3 lost aircraft with 4 fatalities due to incapacitation by hypoxia. In addition, 12 ejections were attributed to loss of cockpit pressure. Nine of the ejections were deliberate and three were accidental, caused by wind blast activation of the face curtain. Three aviators lost their lives following ejection and seven aircraft were lost. While the incidence of loss of cabin pressure in Naval aircraft appears low, it none-the-less presents a definite risk to the aircrew. Lectures on the loss of cabin/cockpit pressurization should continue during indoctrination and refresher physiology training.

To know the frequency of fatal poisoning in Peshawar regarding the toxic agents mostly involved and yearwise percentage. To know the age group and the gender that is most vulnerable to fatal poisoning. Non-interventional (descriptive) type. This study was conducted over a period of five years (1997-2001) at Forensic Medicine Department, Khyber Medical College, Peshawar. The study included 3508 autopsies conducted at Khyber Medical College, Peshawar. Out of these, 52 cases were those caused by fatal poisoning. These were analyzed according to age, gender and the toxic agent involved. t-test was applied as the test of significance. Poisoning was the cause of death in 1.48% of the total autopsies conducted during the five years. Males were more involved than the females, 90.38 %. Suicidal poisoning was present in 17.30% of the total cases and accidental poisoning was found in 80.72% cases, while homicidal cases were 1.29% only. Diacetylmorphine (heroin) was the most commonly involved agent, 65.38 %, of the total cases. The incidence of poisoning was more during the third and fourth decades of life. Diacetylmorphine (heroin) was the main causative agent involved in young males due to accidental over- dosage. Accidental and suicidal deaths should not be considered as inevitable. More elaborative studies are required in this area of recent research to adopt appropriate and adequate measures to save precious lives.

2018-01-01

Child abuse is a sensitive topic among many medical practitioners and the diagnosis of this entity requires awareness about conditions which can mimic physical child abuse. Here, the authors present a case of a 13-year-old school non-attendee who was referred due to multiple scars, over areas prone to accidental as well as non-accidental injury, who underwent medicolegal examination due to suspicion of physical child abuse. On further inquiry, it was discovered that she had easy bruising and poor wound healing. A diagnosis of Ehlers-Danlos syndrome was established and physical child abuse was excluded. This case emphasizes the importance of identifying conditions which may confound the diagnosis of physical child abuse. This is of utmost importance in avoiding adverse legal and psycho-social implications on the child, family and society.

Defect specific maintenance of SG tubes -- How safe is it?

Cizelj, L.; Mavko, B.; Dvorsek, T.

1997-02-01

The efficiency of the defect specific plugging criterion for outside diameter stress corrosion cracking at tube support plates is assessed. The efficiency is defined by three parameters: (1) number of plugged tubes, (2) probability of steam generator tube rupture and (3) predicted accidental leak rate through the defects. A probabilistic model is proposed to quantify the probability of tube rupture, while procedures available in literature were used to define the accidental leak rates. The defect specific plugging criterion was then compared to the performance of traditional (45%) plugging criterion using realistic data from Krsko nuclear power plant. Advantages of themore » defect specific approach over the traditional one are clearly shown. Some hints on the optimization of safe life of steam generator are also given.« less

Usefulness and limitations of postmortem computed tomography in forensic analysis of gunshot injuries: Three case reports.

2016-01-01

Gunshot injury has always been an important field of investigation in postmortem forensic radiology. The localization and retrieval of the bullet and of potentially important fragments are vital to these cases. Using postmortem multidetector-row computed tomography (MDCT) prior to forensic autopsy, we sought to illustrate the importance of this modality in the noninvasive characterization of gunshot wounds. We obtained and analyzed MDCT images in three cases of gunshot wounds (accidental close-range shotgun shooting, suicidal contact gunshot to the head and accidental long-range buckshot shooting). We discuss the value of postmortem MDCT findings in gunshot wound cases by comparing with forensic autopsy findings in Japan, a developing country with miserably low autopsy rate.

Pomara, Cristoforo; D'Errico, Stefano; Riezzo, Irene; Perilli, Gabriela; Volpe, Umberto; Fineschi, Vittorio

2013-12-01

Fatal blast injuries are generally reported in literature as a consequence of the detonation of explosives in war settings. The pattern of lesion depends on the position of the victim in relation to the explosion, on whether the blast tracks through air or water, and whether it happens in the open air or within an enclosed space and the distance from the explosion. Tire explosion-related injuries are rarely reported in literature. This study presents a fatal case of blast overpressure due to the accidental explosion of a truck tire occurring in a tire repair shop. A multidisciplinary approach to the fatality involving forensic pathologists and engineers revealed that the accidental explosion, which caused a series of primary and tertiary blast wave injuries, was due to tire deterioration.

Accidental symmetries and massless quarks in the economical 3-3-1 model

DOE Office of Scientific and Technical Information (OSTI.GOV)

Montero, J. C.; Sánchez–Vega, B. L.

In the framework of a 3-3-1 model with a minimal scalar sector, known as the economical 3-3-1 model, we study its capabilities of generating realistic quark masses. After a detailed study of the symmetries of the model, before and after the spontaneous symmetry breaking, we find a remaining axial symmetry that prevents some quarks from gaining mass at all orders in perturbation theory. Since this accidental symmetry is anomalous, we also consider briefly the possibility of generating their masses for nonperturbative effects. However, we find that nonperturbative effects are not enough to generate the measured masses for the three masslessmore » quarks. Hence, these results imply that the economical 3-3-1 model is not a realistic description of the electroweak interaction.« less

2010-03-07

Transjugular intrahepatic portosystemic shunt (TIPSS) is considered a valid therapeutic option for the treatment of portal hypertension and its complications. The guidelines for this procedure have already been established on the basis of the normal vascular anatomy and of various technical radiological aspects. In some few rare cases, diagnosis of a congenital vascular anomaly can be made accidentally by interventional radiologists, making the procedure of the TIPSS placement extremely difficult or in some cases technically impossible. This report describes a rare vascular malformation characterized by the absence of the right superior vena cava and persistence of the left superior vena cava in a patient with a diagnosis of advanced liver cirrhosis who needed a TIPSS placement in order to control refractory ascites.

Oral Exposure of a Child to a Lithium Ion Battery.

PubMed

Townsend, Janice A; Curran, Ronald

2016-01-01

Battery exposure has the potential for severe morbidity and possible mortality. Accidental exposure is rising with the increased use of button batteries, and young children and older adults are at highest risk for accidental exposure. The purpose of this paper is to report a case of mouth exposure to a lithium ion battery in a boy. A review of the current literature on incidence, diagnosis, and outcomes of battery exposure is presented. When symptoms such as diarrhea, vomiting, and abdominal distress of non-specific origin are present, battery ingestion should be included in the differential diagnosis. Dentists may be the first health professionals to encounter battery exposure, especially in the case of mouth exposures. Knowledge of signs and symptoms are necessary to properly diagnose and refer for medical management.

Fatal cerebral coenurosis in a cat.

1994-07-01

A 6-year-old cat that was laterally recumbent and panting was evaluated because of a 10-day history of progressive neurologic abnormalities. Despite aggressive treatment, the cat died on the day of admission. At necropsy, a 1.5-cm-diameter, fluid-filled cyst was found in the white matter of the left cerebrum. The cyst was identified as a coenurus of Taenia serialis, on the basis of the cyst wall, distribution of scolices, and the shape and dimensions of rostellar hooks. Scolices were found in varying stages of ontogeny, ranging from undifferentiated to nearly mature. Taenia serialis has a canid-lagomorph life cycle, with cats being accidental intermediate hosts. However, the potential exists for rare zoonotic transmission and subsequent serious disease in human beings and other accidental intermediate hosts.

Modified Composite Materials Workshop

Dicus, D. L. (Compiler)

1978-01-01

The reduction or elimination of the hazard which results from accidental release of graphite fibers from composite materials was studied at a workshop. At the workshop, groups were organized to consider six topics: epoxy modifications, epoxy replacement, fiber modifications, fiber coatings and new fibers, hybrids, and fiber release testing. Because of the time required to develop a new material and acquire a design data base, most of the workers concluded that a modified composite material would require about four to five years of development and testing before it could be applied to aircraft structures. The hybrid working group considered that some hybrid composites which reduce the risk of accidental fiber release might be put into service over the near term. The fiber release testing working group recommended a coordinated effort to define a suitable laboratory test.

Evidence Theory Based Uncertainty Quantification in Radiological Risk due to Accidental Release of Radioactivity from a Nuclear Power Plant

NASA Astrophysics Data System (ADS)

Ingale, S. V.; Datta, D.

2010-10-01

Consequence of the accidental release of radioactivity from a nuclear power plant is assessed in terms of exposure or dose to the members of the public. Assessment of risk is routed through this dose computation. Dose computation basically depends on the basic dose assessment model and exposure pathways. One of the exposure pathways is the ingestion of contaminated food. The aim of the present paper is to compute the uncertainty associated with the risk to the members of the public due to the ingestion of contaminated food. The governing parameters of the ingestion dose assessment model being imprecise, we have approached evidence theory to compute the bound of the risk. The uncertainty is addressed by the belief and plausibility fuzzy measures.

Report of accidental CS ingestion among seven patients in central Israel and review of the current literature.

PubMed

Solomon, I; Kochba, I; Eizenkraft, E; Maharshak, N

2003-10-01

A report of seven people who accidentally drank a juice contaminated with CS (o-chlorobenzylidene malononitrile) is given. Due to its mucosal irritating properties, CS (also known as "tear gas") is commonly used by policemen and soldiers in riot control. However, only a few reports of its ingestion by humans exist. Ingestion of CS may cause immediate irritation of the oral mucosa and gastrointestinal symptoms later on. Damage of internal organs, which has been shown in animals but only rarely in humans, is probably related to the dose ingested. The extensive use of CS gas merits recognition of the signs and symptoms of its exposure in order to reduce anxiety in both patients and medical staff and to facilitate fast and efficient management.

Heading and head injuries in soccer.

PubMed

Kirkendall, D T; Jordan, S E; Garrett, W E

2001-01-01

In the world of sports, soccer is unique because of the purposeful use of the unprotected head for controlling and advancing the ball. This skill obviously places the player at risk of head injury and the game does carry some risk. Head injury can be a result of contact of the head with another head (or other body parts), ground, goal post, other unknown objects or even the ball. Such impacts can lead to contusions, fractures, eye injuries, concussions or even, in rare cases, death. Coaches, players, parents and physicians are rightly concerned about the risk of head injury in soccer. Current research shows that selected soccer players have some degree of cognitive dysfunction. It is important to determine the reasons behind such deficits. Purposeful heading has been blamed, but a closer look at the studies that focus on heading has revealed methodological concerns that question the validity of blaming purposeful heading of the ball. The player's history and age (did they play when the ball was leather and could absorb significant amounts of water), alcohol intake, drug intake, learning disabilities, concussion definition and control group use/composition are all factors that cloud the ability to blame purposeful heading. What does seem clear is that a player's history of concussive episodes is a more likely explanation for cognitive deficits. While it is likely that the subconcussive impact of purposeful heading is a doubtful factor in the noted deficits, it is unknown whether multiple subconcussive impacts might have some lingering effects. In addition, it is unknown whether the noted deficits have any affect on daily life. Proper instruction in the technique is critical because if the ball contacts an unprepared head (as in accidental head-ball contacts), the potential for serious injury is possible. To further our understanding of the relationship of heading, head injury and cognitive deficits, we need to: learn more about the actual impact of a ball on the head, verify the exposure to heading at all ages and competitive levels, determine stable estimates of concussive injury rates across the soccer spectrum, conduct prospective longitudinal studies on soccer players focusing on exposure, injury and cognition, and determine the minimum safe age to begin instruction on the skill of heading. Only then will we be able to speak with some authority on the issue of heading and head injuries in soccer.

Major trauma from suspected child abuse: a profile of the patient pathway.

PubMed

Davies, Ffion C; Lecky, Fiona E; Fisher, Ross; Fragoso-Iiguez, Marisol; Coats, Tim J

2017-09-01

Networked organised systems of care for patients with major trauma now exist in many countries, designed around the needs of the majority of patients (90% adults). Non-accidental injury is a significant cause of paediatric major trauma and has a different injury and age profile from accidental injury (AI). This paper compares the prehospital and inhospital phases of the patient pathway for children with suspected abuse, with those accidentally injured. The paediatric database of the national trauma registry of England and Wales, Trauma Audit and Research Network, was interrogated from April 2012 (the launch of the major trauma networks) to June 2015, comparing the patient pathway for cases of suspected child abuse (SCA) with AI. In the study population of 7825 children, 7344 (94%) were classified as AI and 481 (6%) as SCA. SCA cases were younger (median 0.4 years vs 7 years for AI), had a higher Injury Severity Score (median 16vs9 for AI), and had nearly three times higher mortality (5.7%vs2.2% for AI). Other differences included presentation to hospital evenly throughout the day and year, arrival by non-ambulance means to hospital (74%) and delayed presentation to hospital from the time of injury (median 8 hours vs 1.8 hours for AI). Despite more severe injuries, these infants were less likely to receive key interventions in a timely manner. Only 20% arrived to a designated paediatric-capable major trauma centre. Secondary transfer to specialist care, if needed, took a median of 21.6 hours from injury(vs 13.8 hours for AI). These data show that children with major trauma that is inflicted rather than accidental follow a different pathway through the trauma system. The current model of major trauma care is not a good fit for the way in which child victims of suspected abuse present to healthcare. To achieve better care, awareness of this patient profile needs to increase, and trauma networks should adjust their conventional responses. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

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

NASA Astrophysics Data System (ADS)

Palta, M.

2015-12-01

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, when pathogen loading is also high at most sites. These wetlands and waterways are not maintained and managed for ecosystem functions or services; our research suggests that accidental systems should be further examined to determine how they might be utilized and sustained by urban populations, particularly those who are socially vulnerable.

Comparison of whole-body post mortem 3D CT and autopsy evaluation in accidental blunt force traumatic death using the abbreviated injury scale classification.

2013-02-10

Although 3D CT imaging data are available on survivors of accidental blunt trauma, little similar data has been collected and classified on major injuries in victims of fatal injuries. This study compared the sensitivity of post mortem computed tomography (PMCT) with that of conventional autopsy for major trauma findings classified according to the trauma Abbreviated Injury Scale (AIS). Whole-body 3D PMCT imaging data and full autopsy findings were analyzed on 21 victims of accidental blunt force trauma death. All major injuries were classified on the AIS scale with ratings from 3 (serious) to 6 (unsurvivable). Agreement between sensitivity of autopsy and PMCT for major injuries was determined. A total of 195 major injuries were detected (mean per fatality, 9.3; range, 1-14). Skeletal injuries by AIS grade included 37 grade 3, 45 grade 4, 12 grade 5, and 2 grade 6 major findings. Soft tissue injuries included 10 grade 3, 68 grade 4, 16 grade 5, and 5 grade 6 major findings. Of these, PMCT detected 165 (88 skeletal, 77 soft tissue), and autopsy detected 127 (59 skeletal, 68 soft tissue). PMCT agreed with autopsy in 86% and 76% of skeletal and soft tissue injuries, respectively. PMCT detected an additional 37 skeletal and 31 soft tissue injuries that were not identified at autopsy. Autopsy detected 8 skeletal and 22 soft tissue injuries that were not detected by PMCT. PMCT was more sensitive for skeletal (P=0.05) and head and neck region injury (P=0.043) detection. PMCT showed a trend for greater sensitivity than autopsy, but this did not reach statistical significance (P=0.083). 3D PMCT detected significantly more skeletal injuries than autopsy and a similar number of soft tissue injuries to autopsy and promises to be a sensitive tool for detection and classification of skeletal injuries in fatal blunt force accidental trauma. Use of the AIS scale allows standardized categorization and quantification of injuries that contribute to death in such cases and allows more objective comparison between autopsy and PMCT.

Surgical treatment and optical coherence tomographic evaluation for accidental laser-induced full-thickness macular holes.

PubMed

Qi, Y; Wang, Y; You, Q; Tsai, F; Liu, W

2017-07-01

PurposeTo report OCT appearance and surgical outcomes of full-thickness macular holes (MHs) accidentally caused by laser devices.Patients and methodsThis retrospective case series included 11 eyes of 11 patients with laser-induced MHs treated by pars plana vitrectomy, internal limiting membrane (ILM) peeling, and gas or silicone oil tamponade. Evaluations included a full ophthalmic examination, macular spectral-domain optical coherence tomography (SD-OCT), and fundus photography. Main outcome measures is MH closure and final visual acuity; the secondary outcome was the changes of retinal pigment epithelium and photoreceptor layer evaluated by sequential post-operative SD-OCT images.ResultsFive patients were accidentally injured by a yttrium aluminum garnet (YAG) laser and six patients by handheld laser. MH diameters ranged from 272 to 815 μm (mean, 505.5±163.0 μm) preoperatively. Best-corrected visual acuity (BCVA) improved from a mean of 0.90 logMAR (range, counting finger-8/20) preoperatively to a mean of 0.34 logMAR (range, a counting finger-20/20) postoperatively (P=0.001, t=4.521). Seven of 11 patients (63.6%) achieved a BCVA better than 10/20. Ten patients had a subfoveal hyperreflectivity and four patients had a focal choroidal depression subfoveal preoperatively. At the last follow-up, all 11 eyes demonstrated the following: closure of the macular hole, variable degrees of disruption of external limiting membrane (ELM) and outer photoreceptor ellipsoid and interdigitation bands. In 10 eyes, the disruption was in the form of focal defects in the outer retina. After surgery, the subfoveal hyperreflectivity and focal choroidal depression remained.ConclusionAccidental laser-induced full-thickness macular holes can be successfully closed with surgery. Inadvertent retinal injury from laser devices, especially handheld laser injury has occurred with increasing frequency in recent years. However, there is a paucity of data regarding these types of injuries, mostly in the form of case reports. We hereby reported 11 eyes of 11 patients with laser-induced macular holes treated by vitrectomy. All the macular holes closed after surgery and the corresponding visual acuities significantly improved postoperatively.

The constituents and concentrations of pollutants, individual exposures, and biologic responses to air pollution may vary by season and meteorological conditions. However, evidence regarding seasonality of the acute effects of air pollution on mortality is limited and inconsistent. Herein, we examined seasonal patterns in the short-term associations of particulate matter (PM) smaller than 10μm (PM 10 ) with daily mortality in 29 cities of three northeast Asian countries. Stratified time-series models were used to determine whether season altered the effect of PM 10 on mortality. This effect was first quantified within each season and at each location using a time-series model, after which city-specific estimates were pooled using a hierarchical Bayesian model. In all data sets, 3,675,348 non-accidental deaths were registered from 1993 to 2009. In Japan, a 10μg/m 3 increase in PM 10 was significantly associated with increases in non-accidental mortality of 0.44% (95% confidence interval [CI]: 0.03%, 0.8%) in spring and 0.42% (0.02%, 0.82%) in fall. In South Korea, a 10μg/m 3 increase in PM 10 was significantly associated with increases in non-accidental mortality of 0.51% (0.01%, 1.01%) in summer and 0.45% (0.03%, 0.87%) in fall, in cardiovascular disease mortality of 0.96% (0.29%, 1.63%) in fall, and in respiratory disease mortality of 1.57% (0.40%, 2.75%) in fall. In China, a 10μg/m 3 increase in PM 10 was associated with increases in non-accidental mortality of 0.33% (0.01%, 0.66%) in summer and 0.41% (0.09%, 0.73%) in winter, in cardiovascular disease mortality of 0.41% (0.08%, 0.74%) in spring and 0.33% (0.02%, 0.64%) in winter, and in respiratory diseases mortality of 0.78% (0.27%, 1.30%) in winter. Our analyses suggest that the acute effect of particulate air pollution could vary seasonally and geographically. Copyright © 2016 Elsevier B.V. All rights reserved.

Percutaneous transesophageal gastro-tubing (PTEG) as an alternative long-term tube feeding procedure when gastrostomy is not feasible

PubMed Central

Toh Yoon, Ezekiel Wong; Nishihara, Kazuki

2017-01-01

Background: Percutaneous transesophageal gastro-tubing (PTEG) is a minimally invasive technique to access the gut via an esophagostomy. However, this procedure is not well known and the literature available is still fairly limited. This observational study was conducted to evaluate our experience using this method as an alternative long-term tube feeding procedure when gastrostomy is not suitable. Methods: A total of 15 patients (10 males and 5 females) who underwent PTEG at our institution from 2012 to 2016 were observed and analyzed in this study. Results: The average age was 80.1 (71–93) years. Underlying conditions that required PTEG were previous gastric resection in 11 patients, left diaphragm disorder in 2 patients, interposing transverse colon between the abdominal wall and anterior gastric wall in 1 patient, and severe gastrostomy site leakage in 1 patient. Tube placement was successful in all patients by approaching the left side of the neck, using a 15 Fr size tube. The mean postoperative length of stay was 22 (8–48) days. Postoperative adverse events included accidental tube dislodgement in three patients, tracheoesophageal fistula in one patient, inferior thyroid artery injury in one patient and thyroid gland mispuncture in one patient. There was no procedure-related mortality nor mortality at 30 days. Eight patients were discharged with some oral intake. Conclusions: PTEG is feasible in patients requiring long-term tube feeding for whom gastrostomy is unsuitable. It is an effective long-term tube feeding procedure and should be offered as a more comfortable alternative to nasogastric tubing. PMID:29204186

Percutaneous transesophageal gastro-tubing (PTEG) is a minimally invasive technique to access the gut via an esophagostomy. However, this procedure is not well known and the literature available is still fairly limited. This observational study was conducted to evaluate our experience using this method as an alternative long-term tube feeding procedure when gastrostomy is not suitable. A total of 15 patients (10 males and 5 females) who underwent PTEG at our institution from 2012 to 2016 were observed and analyzed in this study. The average age was 80.1 (71-93) years. Underlying conditions that required PTEG were previous gastric resection in 11 patients, left diaphragm disorder in 2 patients, interposing transverse colon between the abdominal wall and anterior gastric wall in 1 patient, and severe gastrostomy site leakage in 1 patient. Tube placement was successful in all patients by approaching the left side of the neck, using a 15 Fr size tube. The mean postoperative length of stay was 22 (8-48) days. Postoperative adverse events included accidental tube dislodgement in three patients, tracheoesophageal fistula in one patient, inferior thyroid artery injury in one patient and thyroid gland mispuncture in one patient. There was no procedure-related mortality nor mortality at 30 days. Eight patients were discharged with some oral intake. PTEG is feasible in patients requiring long-term tube feeding for whom gastrostomy is unsuitable. It is an effective long-term tube feeding procedure and should be offered as a more comfortable alternative to nasogastric tubing.

Drug overdose now exceeds car accidents as the leading cause of accidental death in the United States. Of those drug overdoses, a large percentage of the deaths are due to heroin and/or pharmaceutical overdose, specifically misuse of prescription opioid analgesics. It is imperative, then, that we understand the mechanisms that lead to opioid abuse and addiction. The rewarding actions of opioids are mediated largely by the mu-opioid receptor (MOR), and signaling by this receptor is modulated by various interacting proteins. The neurotransmitter dopamine also contributes to opioid reward, and opioid addiction has been linked to reduced expression of dopamine D2 receptors (D2R) in the brain. That said, it is not known if alterations in the expression of these proteins relate to drug exposure and/or to the "addiction-like" behavior exhibited for the drug. Here, we held total drug self-administration constant across acquisition and showed that reduced expression of the D2R and the MOR interacting protein, Wntless, in the medial prefrontal cortex was associated with greater addiction-like behavior for heroin in general and with a greater willingness to work for the drug in particular. In contrast, reduced expression of the D2R in the nucleus accumbens and hippocampus was correlated with greater seeking during signaled nonavailability of the drug. Taken together, these data link reduced expression of both the D2R and Wntless to the explicit motivation for the drug rather than to differences in total drug intake per se.
