    Needleman, H L

    1998-12-01

    In 1991, the Public Health Service published the Strategic Plan for the Elimination of Childhood Lead Poisoning. This document marked a fundamental shift in federal policy from finding and treating lead-poisoned children to authentic primary prevention. It spelled out a 15-year strategy to achieve this goal and provided a cost-benefit analysis showing that the monetized benefits far exceeded the costs of abatement. A strong national effort to eliminate the disease developed. Now, 7 years after publication of the plan, primary prevention of lead exposure has been abandoned. This article examines the role of some prevailing attitudes and institutions in derailing the effort. Some institutions--the lead industry, real estate interests, and insurance interests--behaved as anticipated. Others, including private pediatricians, the American Academy of Pediatrics, some federal agencies, and a public interest group ostensibly dedicated to eliminating lead poisoning, also played an unexpected part in derailing the plan.

  8. Are local laws the key to ending childhood lead poisoning?

    Korfmacher, Katrina S; Hanley, Michael L

    2013-08-01

    Although lead paint was banned by federal law in 1978, it continues to poison children living in homes built before that time. The lifelong effects of childhood exposure to even small amounts of lead are well established by medical research. Federal and state laws have reduced rates of lead poisoning significantly in the past three decades. However, pockets of high rates of lead poisoning remain, primarily in low-income urban neighborhoods with older housing stock. Recently, several municipalities have passed local lead laws to reduce lead hazards in high-risk areas. There has been no systematic attempt to compare the design and effectiveness of these local policies. To address this gap, we conducted comparative case studies of eight innovative lead laws promulgated since 2000. The laws used a wide variety of legal structures and tools, although certain elements were common. The impact of the policies was intertwined with local housing, economic, and legal environments. While data do not yet exist to systematically evaluate the impact of these laws on lead poisoning rates, our analysis suggests that local laws hold great promise for reducing lead hazards in children's homes.

    Lead concentrations and isotopic compositions in blood samples of 34 children (ages 2-17 years) living within a 113 km{sup 2} area of a silver-zinc-lead smelter plant in Torreon, Mexico were compared to those of associated environmental samples (soil, aerosols, and outdoor and indoor dust) to identify the principal source(s) of environmental and human lead contamination in the area. Lead concentrations of soil and outdoor dust ranged 130-12,050 and 150-14,365 {mu}g g{sup -1}, respectively. Concentrations were greatest near the smelter, with the highest levels corresponding with the prevailing wind direction, and orders of magnitude above background concentrations of 7.3-33.3 {mu}g g{sup -1}. Atmospheric lead depositions in the city varied between 130 and 1350 {mu}g m{sup -2} d{sup -1}, again with highest rates <1 km from the smelter. Blood lead (PbB) concentrations (11.0{+-}5.3 {mu}g dl{sup -1}) levels in the children ranged 5.0-25.8 {mu}g dl{sup -1}, which is 3-14 times higher than the current average (1.9 {mu}g dl{sup -1}) of children (ages 1-5 years) in the US. Lead isotopic ratios ({sup 206}Pb/{sup 207}Pb, {sup 208}Pb/{sup 207}Pb) of the urban dust and soil (1.200{+-}0.009, 2.467{+-}0.003), aerosols (1.200{+-}0.002, 2.466{+-}0.002), and PbB (1.199{+-}0.001, 2.468{+-}0.002) were indistinguishable from each other, as well as those of the lead ores processed at the smelter (1.199{+-}0.007, 2.473{+-}0.007). Consequently, an elevated PbB concentrations of the children in Torreon, as well as in their environment, are still dominated by industrial emissions from the smelter located within the city, in spite of new controls on atmospheric releases from the facility. - Highlights: {yields} Pb contents in environmental samples evidenced chronic Pb pollution in Torreon. {yields} Pb stable isotopes evidenced contemporary emissions from the Ag-Cod-Pb-Zn smelter. {yields} Pb urban dust and soil account for most of the childhood lead poisoning in Torreon.{yields} Levels of

  11. Emerging aspects of assessing lead poisoning in childhood

    2009-01-01

    Full Text Available This review covers the epidemiology of lead poisoning in children on a global scale. Newer sources of lead poisoning are identified. The methods that are used to assess a population of children exposed to lead are discussed, together with the ways of undertaking an exposure risk assessment; this includes assessing the time course and identifying sources of lead exposure. Human assessment measures for lead toxicity, such as blood lead concentrations, deciduous tooth lead, and use of zinc protoporphyrin estimations are evaluated. The role of isotopic fingerprinting techniques for identifying environmental sources of exposure is discussed. Among emerging data on the cognitive and behavioral effects of lead on children, the review considers the growing evidence of neurocognitive dysfunction with blood lead concentrations even below 10 |[mu]|g/dl. The challenge of assessing and explaining the risk that applies to an individual as opposed to a population is discussed. Intervention strategies to mitigate risk from lead are examined together with the limited role for and limitations of chelation therapy for lead. Lessons learned from managing a population lead-dust exposure event in Esperance, Western Australia in 2007 are discussed throughout the review.

    Despite the gradual decrease in childhood lead poisoning in the United States, the risk for lead poisoning among African refugee children who resettle in the United States remains elevated. Communication methods implemented by resettlement agencies in the public health system for preventing childhood lead poisoning in this at-risk population warrant further investigation. We utilized structured interviews with key stakeholders (resettlement agencies, social service agencies developed by African refugees and resettled Somali refugees) involved in the refugee resettlement process to (1) describe the agency's role in the refugee resettlement process; (2) examine communication methods utilized and barriers experienced by the public health system in reference to childhood lead poisoning; (3) describe the refugee population's perception of childhood lead poisoning; (4) examine general challenges experienced by the public health system and the refugee population during the resettlement process; and (5) describe stakeholders' recommendations to improve health communication efforts. Based on our findings, we propose that communities are important determinants in health-related problems for refugee populations. Each community has its own environment and public health system that interacts with each other to influence health risks and risk perceptions of its populations. We advocate that understanding a community's ecology and implementing a culture-centered approach is essential for the public health system to help educate and prevent communication inequalities and health disparities among an at-risk African refugee population. This action can reduce a population's resistance to communication and help build a community's capacity to address a persistent public health problem, such as childhood lead poisoning.

  14. Childhood lead poisoning in 2 families associated with spices used in food preparation.

    2005-08-01

    Although most cases of childhood lead poisoning are caused by contaminated paint and dust in older homes, a variety of unusual sources of lead exposure are occasionally found. We report here 2 families whose children were poisoned by lead-contaminated spices that were purchased in foreign countries, brought to the United States, and then used in the preparation of the family's food. Six children (2-17 years old) in a family from the Republic of Georgia were poisoned by swanuri marili (lead content: 100 and 2040 mg/kg in separately sampled products) and kharchos suneli (zafron) lead content: 23,100 mg/kg) purchased from a street vendor in Tbilisi, Georgia. The second family had purchased a mixture of spices called kozhambu (lead content: 310 mg/kg) while traveling in India. Both the parents and their 2-year-old child subsequently suffered lead poisoning. The young children in both families required short-term chelation to bring their blood lead levels down to a safer range. Clinicians should be vigilant for all sources of lead contamination, including spices, when whole families are found to have elevated blood lead levels despite a confirmed lead-safe home environment. Families traveling abroad should be aware of the potential health risks associated with the purchase and use of spices that have not been tested for purity. PMID:16061585

    2016-01-01

    Background: From 2010 through 2013, integrated health and environmental responses addressed an unprecedented epidemic lead poisoning in Zamfara State, northern Nigeria. Artisanal gold mining caused widespread contamination resulting in the deaths of > 400 children. Socioeconomic, logistic, and security challenges required remediation and medical protocols within the context of local resources, labor practices, and cultural traditions. Objectives: Our aim was to implement emergency environmental remediation to abate exposures to 17,000 lead poisoned villagers, to facilitate chelation treatment of children ≤ 5 years old, and to establish local technical capacity and lead health advocacy programs to prevent future disasters. Methods: U.S. hazardous waste removal protocols were modified to accommodate local agricultural practices. Remediation was conducted over 4 years in three phases, progressing from an emergency response by international personnel to comprehensive cleanup funded and accomplished by the Nigerian government. Results: More than 27,000 m3 of contaminated soils and mining waste were removed from 820 residences and ore processing areas in eight villages, largely by hand labor, and disposed in constructed landfills. Excavated areas were capped with clean soils (≤ 25 mg/kg lead), decreasing soil lead concentrations by 89%, and 2,349 children received chelation treatment. Pre-chelation geometric mean blood lead levels for children ≤ 5 years old decreased from 149 μg/dL to 15 μg/dL over the 4-year remedial program. Conclusions: The unprecedented outbreak and response demonstrate that, given sufficient political will and modest investment, the world’s most challenging environmental health crises can be addressed by adapting proven response protocols to the capabilities of host countries.

    Successful public health media campaigns promote messages, increase awareness, engage the public, and encourage behavior change. Between 2004 and 2006, the Lead Poisoning Prevention Program of the New York City Department of Health and Mental Hygiene conducted a media campaign grounded in social learning theory and the social marketing model to increase parents' awareness of childhood lead poisoning, ways to protect their children, and property owners' legal responsibility to fix peeling lead paint safely, and increase awareness of regulatory changes and encourage enforcement of New York City's Local Law 1 of 2004. Campaign materials were focus group tested and the campaign was refined annually. The campaign ran city-wide and in targeted high-risk neighborhoods. Neighborhoods and media venue (bus, train, kiosk, and store) changed annually, based on population risk factors and venue availability. Exposure to the campaign, campaign-related knowledge, and behavior were assessed using pre- and postcampaign street intercept surveys. Results showed that campaign reached the targeted population, and had an impact on knowledge of lead poisoning prevention measures as evidenced by increased knowledge of lead paint exposures sources in one year and increased knowledge of preventive behaviors in another year; these improvements were observed for both genders and most ethnic, primary language, educational attainment, and age groups in each year. Lessons learned indicate that well-targeted media campaigns, designed with audience participation, can reach parents through various venues, and improve key knowledge areas. Evaluation challenges faced include high levels of knowledge at baseline, competing media messages, and balancing between program needs and evaluation design. PMID:25558876

    2013-01-01

    Background: In 2010, Médecins Sans Frontières discovered a lead poisoning outbreak linked to artisanal gold processing in northwestern Nigeria. The outbreak has killed approximately 400 young children and affected thousands more. Objectives: Our aim was to undertake an interdisciplinary geological- and health-science assessment to clarify lead sources and exposure pathways, identify additional toxicants of concern and populations at risk, and examine potential for similar lead poisoning globally. Methods: We applied diverse analytical methods to ore samples, soil and sweep samples from villages and family compounds, and plant foodstuff samples. Results: Natural weathering of lead-rich gold ores before mining formed abundant, highly gastric-bioaccessible lead carbonates. The same fingerprint of lead minerals found in all sample types confirms that ore processing caused extreme contamination, with up to 185,000 ppm lead in soils/sweep samples and up to 145 ppm lead in plant foodstuffs. Incidental ingestion of soils via hand-to-mouth transmission and of dusts cleared from the respiratory tract is the dominant exposure pathway. Consumption of water and foodstuffs contaminated by the processing is likely lesser, but these are still significant exposure pathways. Although young children suffered the most immediate and severe consequences, results indicate that older children, adult workers, pregnant women, and breastfed infants are also at risk for lead poisoning. Mercury, arsenic, manganese, antimony, and crystalline silica exposures pose additional health threats. Conclusions: Results inform ongoing efforts in Nigeria to assess lead contamination and poisoning, treat victims, mitigate exposures, and remediate contamination. Ore deposit geology, pre-mining weathering, and burgeoning artisanal mining may combine to cause similar lead poisoning disasters elsewhere globally.

    The study objectives were to estimate lead poisoning prevalence among children living next to an industrial area, to compare it to that in a control population, and to establish clinical and biological follow-up of the poisoned children. This is a descriptive cross-sectional study including 150 children (exposed and unexposed) performed between January 2012 and April 2013. It was meant to determine blood lead levels (BLLs) in children considered to be an exposed population (EP N 90), living in the industrial area Ain Nokb Fez compared with BLLs of children of other areas belonging to the same city supposed to be unexposed [UP (N = 60)]. A sociodemographic questionnaire was obtained, and a blood lead analysis was performed. Clinical and biological follow-up has been performed of poisoned children. The sample consisted of 90 EP children with an average age of 6.82 ± 3.32 years and male-to-female sex ratio (SR) of 1.5 and 60 UP children with an average age of 6.45 ± 3.29 years and an SR of 1.2. Among the 150 children recruited, the average of BLLs was 58.21 ± 36 µg/L (18-202.3 μg/L). The average of BLLs in EP children (71 ± 40 µg/L) was statistically greater (p poisoned children belonged to the EP group at a prevalence of 21.1 %. The clinical and biological examinations of poisoned children showed a few perturbations such as anemia, hypocalcaemia, and deficiencies in magnesium and iron. No renal disease or objective neurological disorders were observed. In the follow-up of the children with BLL ≥100 µg/L (19 cases). BLL monitoring showed a significant decrease in average of blood concentration ranging from 136.75 ± 32.59 to 104.58 ± 32.73 µg/L (p poisoning prevalence (p poisoning (21.1 %) in EP children.

    A detailed description is given of the complex pathological picture observed in the case of a worker with 30 years' occupational exposure to lead in an accumulator factory (evolution of the disease, clinical findings, autopsy). In spite of a typical clinical picture, lead is not held responsible for the terminal encephalopathy, in view of the fact that Alzheimer's syndrome was discovered at autopsy. However, the neurovegetative asthenia and progressive kidney disease without hypertonia, but with uraemia, which preceded the encephalopathy are in all probability due to chronic lead poisoning. The article discusses the diagnosis and symptomatology of chronic lead poisoning, encephalopathy and kidney disease.

    With NASA contracts, Whittaker Corporations Space Science division has developed an electro-optical instrument to mass screen for lead poisoning. Device is portable and detects protoporphyrin in whole blood. Free corpuscular porphyrins occur as an early effect of lead ingestion. Also detects lead in urine used to confirm blood tests. Test is inexpensive and can be applied by relatively unskilled personnel. Similar Whittaker fluorometry device called "drug screen" can measure morphine and quinine in urine much faster and cheaper than other methods.

  6. Lead poisoning in dogs

    International Nuclear Information System (INIS)

    Lead poisoning was diagnosed and studied in 60 dogs. It was found that lead poisoning is a common disease of young dogs, especially in the summer and fall, and is related to their chewing and eating habits resulting in the ingestion of paint, linoleum, or other lead-containing materials. The signs were characterized by gastrointestinal dysfunction (colic, vomiting, and diarrhea) and nervous disorders (convulsions, hysteria, nervousness, behavioral changes). The blood findings, which the authors consider nearly pathognomonic, consisted of numerous stippled and immature (especially nucleated) erythrocytes in the absence of severe anemia. Protein and casts were frequently found in the urine. Radiography sometimes revealed lead-containing particles in the gastro-intestinal tract, and lead lines were occasionally detected in the metaphysis of long bones in immature dogs. Treatment with calcium ethylenediamine-tetraacetic acid resulted in rapid and often dramatic recoveries in nearly all instances. Removal of lead from the gastrointestinal tract and treatment to relieve pronounced central nervous disorders was sometimes necessary. 40 references, 6 figures, 7 tables

    Full Text Available BACKGROUND Accidents including poisoning are one of the leading causes of morbidity and mortality among children in the west. Poisoning, while never accounting for a large number of accidental deaths, have acquired prominence now because they have not decreased at the same rate as the infectious diseases. METHODS An observational study was done in Department of Paediatrics KIMS Bangalore to know the incidence and pattern of childhood poisoning, to know the morbidity and mortality resulting from childhood poisoning. 86 children aged between 0-18 years were admitted to the paediatric intensive care unit with history of poisoning during the 2-year period of the study (Nov 13-Nov 15 were included. Diagnosis of poisoning was made on the basis of history and examination findings, Relevant investigations were done and Profile of patients with poisoning, their symptoms, type of poisoning and outcome were analysed. RESULTS The average duration of stay in the hospital was 2.7 days. Poisoning was accidental in 80 (93% patients whereas suicidal intent was present in only 6 (7% patients. Total 5 (5.8% patients died of which 4 were due to insecticide and pesticide poisoning and one was due to kerosene poisoning. CONCLUSION In the present study the probable reason for higher incidence of poisoning by insecticides & pesticides could be the involvement of higher age group and more involvement of adolescent children.

    Full Text Available Although blood lead levels (BLLs in US children have dramatically declined over the past 40 years, there remain pockets of children living in areas with elevated BLLs. While some increases (≥10 μg/dL may be associated with legacy lead paint, ambient air lead may be contributing to the problem. A deidentified dataset of information on over 60,000 Kansas children under 3 years of age who were tested for BLL was provided through the Kansas Environmental Public Health Tracking Network for the period 2000–2005. Using ArcGIS, we calculated distance (in miles from a lead-emitting industry referred to as a toxic release inventory (TRI site. The USEPA TRI database tracks the management of certain toxic chemicals that may pose a threat to human health. US facilities in different industry sectors must report annually amount of substances like lead into the environment including their exact location. Distance from a TRI site was inversely related to BLL after controlling for area-level poverty and pre-1950 housing. The results of our evaluation indicate there is a significant relationship between proximity to lead industry and childhood BLLs. Proximity to sources of lead emissions should be evaluated as a possible factor when identifying children for targeted BLL testing.

    Between October 1982 and June 1983, 43 patients were identified with symptomatic lead poisoning in three Arab villages of the Nablus district. Because of the clustering of clinical poisoning by household units, investigation was focussed on potential sources common to all members of the households. After excluding water, olive oil and a variety of foodstuff, lead in high concentrations was discovered in locally ground flour in all affected households. The source of poisoning was lead poured into the fissures between the metal housing and the driveshaft of the millstone. Significant lead contamination of freshly ground flour was demonstrated in 23% of the 146 community flour mills operating in West Bank villages. Since the completion of these studies, similar outbreaks of lead poisoning caused by contaminated flourmills have been identified in the Upper Galilee and in Spain. As the methods of milling in the Mediterranean area are similar, a coordinated international effort is needed in order to eliminate this health hazard from countries where similar community stone mills are still in use.

    Full Text Available El presente artículo hace una revisión del manejo clínico de la intoxicación por plomo en la niñez. Se menciona las definiciones de las diferentes técnicas de medición usadas para la determinación de plomo, y se destacan sus ventajas y posibles limitaciones. La medición de los niveles de plomo sanguíneo puede realizarse utilizando muestra de sangre anticoagulada por espectrofotometría de absorción atómica voltametría anódica. Sin embargo, un método más eficiente para medir las concentraciones de plomo en hueso es mediante fluorescencia de Rayos X o para la determinación sistémica en un nivel bioquímico una técnica adecuada es la determinación de los niveles de plomo en orina. El tratamiento incluye la eliminación de la fuente de exposición, cambios en los hábitos de los niños y una dieta adecuada en calcio y hierro. La quelación con edetato de calcio y succimer elimina el plomo del esqueleto, el cual es eliminado por riñón; puede salvar vidas cuando la intoxicación es importante, y existe una reducción a corto plazo seguida de un aumento subsecuente de los niveles de plomo sanguíneo. En casos graves suele requerirse de dosis repetidas. La terapia de quelación puede ser necesaria en casos de niveles de plomo sanguíneo por arriba de 45 µg/dl. La quelación reduce los niveles de plomo sanguíneo y los síntomas asociados, sin embargo, la disminución cognoscitiva puede ser irreversible, por lo que la utilización de medidas preventivas es mucho mejor que las de curación.This paper reviews the clinical management of children with lead poisoning. A first step is to define the measures to be used in their assessment and be aware of the limitations. Measurements of blood lead levels can be made on anti-coagulated whole blood samples using either: atomic absorption spectroscopy or anodic stripping voltametry. However a more accurate method is fluorescent RX'ray of the skeleton or systematic biochemical tests of lead

    1972-07-01

    Lead poisoning was diagnosed post-mortem in 34 simian primates, 11 parrots, and 3 Australian fruit bats at the National Zoological Park. Diagnoses were made by the finding of acid-fast intranuclear inclusion bodies in renal epithelia or hepatocytes and, in most cases, by finding excess lead in samples of liver. The estimated prevalence of lead intoxication among autopsied primates and parrots was 44% and 50% respectively. Leaded paint was found in many animal enclosures at this zoo and it was available to all the lead-poisoned animals in this study. The finding of renal intranuclear inclusion bodies in animals at several zoos, scattered reports of lead intoxication of animals dwelling in various zoos, the occurrence of leaded paint in many zoos and the high incidence of lead poisoning at this zoo, indicated that lead poisoning of zoo animals is much more common than was previously thought.

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

    1988-01-01

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

    Acute and chronic lead poisoning is occurring throughout China and is a major cause of childhood morbidity. The Chinese government's emphasis on industrial development and poverty reduction has, over the past three decades, decreased by 500 million the number of people surviving on less than one dollar per day, but has caused significant environmental degradation that threatens public health. Drawing upon in-depth interviews conducted in 2009 and 2010 with families affected by lead poisoning, environmental activists, journalists, government and civil society organization officials in Shaanxi, Henan, Hunan, and Yunnan provinces, as well as a review of scientific and Chinese media, and health and environmental legal and policy analysis, we examine the intersection of civil, political, economic, and social rights related to access to information, screening, treatment, and remediation related to lead poisoning. In-depth interviews in each province uncovered: censorship and intimidation of journalists, environmental activists, and parents seeking information about sources and prevention of lead poisoning; denial of screening for lead poisoning, often based upon arbitrary eligibility criteria; and inadequate and inappropriate treatment being promoted and provided by health facilities. Over the past decade, the Chinese government has prioritized health care and invested billions of dollars towards universal health coverage, and strengthened environmental to address industrial pollution and guarantee access to information on the environment. Yet, despite these reforms, information remains constrained and citizens seeking information and redress are sometimes arrested, in violation of Chinese and international law. Local government officials and national environmental policies continue to prioritize economic development over environmental protection. To effectively address lead poisoning requires an emphasis on prevention, and to combat industrial pollution requires

    Over the past ten years there has been increasing recognition of subacute and chronic lead poisoning and a growing awareness of its pathophysiology and clinical effects. Besides the classic manifestations of abdominal colic, seizures, and anemia progressing to gout, renal disease, and neuropathy, more subtle manifestations are now being increasingly recognized, such as the development of hypertension, neurobehavioral changes, reproductive and endocrine abnormalities, a possible role in carcinogenesis, and an overall increase in morbidity and mortality. Lead was one of the seven metals of antiquity, and it has accompanied the Eurasian and American civilizations since their beginnings. Lead is an extremely pernicious metal with a multitude of adverse effects. The recurring nature of lead poisoning throughout the development of civilization can truly be referred to as the saturnine curse. 16 references.

    Full Text Available Lead poisoning is a historic universal disease. Acute or chronic lead exposure may cause reversible or even permanent damages in human beings. Environmental lead exposure is a global health concern in children. Occupational lead poisoning is still a health issue, particularly in developing countries. During the last decades, new methods and medications have been advocated for the prevention and treatment of lead poisoning. This review deals mainly with recent developments in the management of lead poisoning. Sources of lead exposure are introduced, and methods for the primary prevention of lead poisoning are discussed. Details for the screening of adults and children are also explained to serve as a practical guideline for the secondary prevention. Standard chelation therapy in different groups and up-to-date less toxic new medications for the treatment of lead poisoning are finally discussed. Our published clinical research on the therapeutic effects of garlic tablets in mild to moderate occupational lead poisoning will also be discussed.

    This study investigated the prevalence of elevated blood lead (PbB) levels in children 1-6 years old in Kaduna, a medium size city in northern Nigeria. Mean PbB was found to be 10.6 micrograms/dl, and 2% of the children had PbB levels greater than 30 micrograms/dl. Highest average PbB levels were found in children 5 years old and was attributed to the tendency for this age group to play longer in contaminated outdoor environments. The strongest associations were found between PbB and whether the family owned a car or lived in a house on a tarred road. Potential sources of lead in the city as well as household and behavior risk factors likely to result in exposure of children to lead are discussed. This study provides additional data pointing to childhood lead poisoning as being a major public health problem in urban areas of Africa.

    Full Text Available Abstract Background Lead poisoning is a common occupational health hazard in developing countries and many misdiagnoses and malpractices may occur due to unawareness of lead poisoning symptoms. Case presentation We report a case of occupational lead poisoning in an adult battery worker with abdominal colic who initially underwent appendectomy with removal of normal appendix. Later on he was diagnosed with lead poisoning and was treated appropriately with lead chelator (CaNa2EDTA. Conclusion Lead poisoning is frequently overlooked as the differential diagnosis of acute abdomen which may result in unnecessary surgery. Appropriate occupational history taking is helpful in making a correct diagnosis. Occupational lead poisoning is a preventable disorder and a serious challenge for the health and labor authorities in developing countries.

    Full Text Available Lead is a natural element that is persistent in water and soil. Human exposure occurs primarily through diet, air, drinking water and ingestion of paint chips. Absorption is increased in persons suffering from iron and calcium deficiency. Lead is a multitargated toxicant, causing effects in the gastrointestinal tract, hematopoietic system, cardiovascular system, central and peripheral nervous systems, kidneys, immune system, and reproductive system. Lead poisoning is a common environmental health hazard in developing countries. Incidences of lead poisoning are seen in all age groups, especially in children’s and adults working in lead-based industries, where many workers still remain unaware of the adverse effects of exposure to unusually high levels of lead. Unfamiliarity with the symptoms of lead poisoning results in miss or delayed diagnosis, inadequate treatment, and patients’ continuous exposure in the work environment. Lead intoxication symptoms such as abdominal pain, constipation, nausea, vomiting etc make lead poisoning an important diagnosis to be differentiated from many gastrointestinal and surgical diseases. For diagnosis of lead poisoning, paying attention to a good occupational history, detail knowledge about lead poisoning symptoms and its sources are essential. For this study, relevant literature was searched, retrieved and synopsized with respect to its sources. Lead poisoning symptoms and few case studies of lead poisoning which initially was misdiagnosed hence our study will be helpful to front-line practitioners and family physicians. They can make great contributions to the discovery of occupational diseases in the future.

    Lead poisoning, associated with ingestion of spent lead shot, was diagnosed in an adult female Pacific loon (Gavia pacifica) observed with partial paralysis on 13 June 2002 and found dead on 16 June 2002 on Kigigak Island, Yukon Delta National Wildlife Refuge, western Alaska, USA. A necropsy revealed three pellets of ingested lead shot in the loona??s gizzard and a lead liver concentration of 31 ppm wet weight, which was consistent with metallic lead poisoning. This is the first report of lead poisoning in a Pacific loon and is the only account of lead toxicosis associated with ingestion of lead shot in any loon species breeding in Alaska.

    2015-05-01

    Childhood lead exposure and poisoning near primary lead smelters continues in developed and developing countries. In the United States, the problem of lead poisoning in children caused by smelter emissions was first documented in the early 1970s. In 1978, Environmental Protection Agency set National Ambient Air Quality Standards for lead. Attainment of this lead standard in areas near operating lead smelters took twenty to thirty years. Childhood lead exposure and poisoning continued to occur after the lead National Ambient Air Quality Standards were set and before compliance was achieved. This article analyzes and discusses the factors that led to the eventual achievement of the 1978 lead National Ambient Air Quality Standards near primary smelters and the reduction of children's blood lead levels in surrounding communities. Factors such as federal and state regulation, monitoring of emissions, public health activities such as blood lead surveillance and health education, relocation of children, environmental group and community advocacy, and litigation all played a role.

    Full Text Available Lead poisoning is one of the oldest, permanent hazards in the world and Iran is not excluded and has the same risk of lead toxicity. Humans have known about the potential hazards of lead poisoning for centuries. Lead is widespread in natural substances, and almost all people are in touch with this insidiously toxic heavy metal in different ways either in workplace or at homes. The level of exposure is higher in most of countries because of extensive use of lead containing materials in normal life and the environment.

    Full Text Available Background Lead pollution is a global problem both in developed and developing countries. Lead poisoning is associated with decreased glomerular filtration rate (GFR and is a risk factor for acute kidney injury (AKI. Serum cystatin-C is a more precise test of GFR than serum creatinine level, as serum cystatin-C levels rise earlier than serum creatinine, when GFR decreases. Objective To assess for a possible correlation between lead poisoning and cystatin-C levels in children. Methods We conducted a cross-sectional study in children aged 6-11 years with a history of lead poisoning from elementary schools in Talawaan District, North Minahasa Regency from July to October 2013. Cystatin-C and blood lead levels (BLL were measured in all subjects. Spearman’s rho test was used to analyze a potential correlation between BLL and cystatin-C level. Results This study included 41 children, comprising 21 boys and 20 girls. Their median age was 8.50 (range 6.8-10.7 years. Elevated levels of cystatin-C did not exceed normal values, however, we found a positive correlation between BLL and cystatin C (r=0.419, P=0.006. Conclusion There is a positive correlation between BLL and cystatin C level in children with lead poisoning. Regular monitoring of BLL, medical intervention, and an epidemiological study to help find the sources of contamination are needed for children with lead poisoning.

    2005-01-01

    Exposure to toxic metals remains a widespread occupational and environmental problem in world. There have been a number of reports in the recent past suggesting an incidence of childhood lead poisoning and chronic arsenic poisoning due to contaminated drinking water in many areas of West Bengal in India and Bangladesh has become a national calamity. Low level metal exposure in humans is caused by air, food and water intake. Lead and arsenic generally interferes with a number of body functions such as the central nervous system (CNS), the haematopoietic system, liver and kidneys. Over the past few decades there has been growing awareness and concern that the toxic biochemical and functional effects are occurring at a lower level of metal exposure than those that produce overt clinical and pathological signs and symptoms. Despite many years of research, we are still far from an effective treatment of chronic plumbism and arsenicosis. Medical treatment of acute and chronic lead and arsenic toxicity is furnished by chelating agents. Chelating agents are organic compounds capable of linking together metal ions to form complex ring-like structures called chelates. They have been used clinically as antidotes for acute and chronic poisoning. 2, 3-dimercaprol (BAL) has long been the mainstay of chelation therapy for lead or arsenic poisoning. Meso 2, 3, -dimercaptosuccinic acid (DMSA) has been tried successfully in animals as well as in a few cases of human lead and arsenic poisoning. DMSA could be a safe and effective method for treating lead or arsenic poisoning, but one of the major disadvantages of chelation with DMSA has been its inability to remove lead from the intracellular sites because of its lipophobic nature. Further, it does not provide protection in terms of clinical/ biochemical recovery. A new trend in chelation therapy is to use combined treatment. This includes the use of structurally different chelators or a combination of an adjuvant and a chelator to

    Lead-induced mortality appears to have been a major factor in the decline of the California condor, Gymnogyps californianus. We orally dosed turkey vultures (Cathartes aura) with BB-sized lead shot from January 1988 through July 1988 to determine physiological response (delta-aminolevulinic acid dehydratase inhibition, erythrocyte protoporphyrin levels, anemia), diagnostic tissue lead concentrations (blood, liver, and kidney), and comparative sensitivity of this species. Two turkey vultures died and two became so intoxicated they were euthanized. Overall, responses of measured parameters were comparable to other species exposed to lead although there was considerable individual variation. Survival time (143-211 days), even with the large number of shot and constant redosing, was much longer than reported for other species of birds, suggesting considerable tolerance by turkey vultures to the deleterious effects of lead ingestion. Based on these observations, turkey vultures appear to be poor models for assessing the risk of lead poisoning to California condors or predicting their physiological response.

    2008-03-01

    A 37-year-old man was admitted to hospital after complaining of abdominal pain for the past two weeks. On admission the abdominal radiograph showed multiple radio-opaque flecks dispersed throughout the gastrointestinal tract. Blood testing showed hemoglobin level 8.7 g/dL and a blood lead level of 112.4 microg/dL. The family interview revealed that the patient had pica-like behavior since childhood. He was a site foreman and had been ingesting pieces of roofing plates for a few weeks. The patient was treated with laxatives and CaNa(2)EDTA therapy was initiated. The blood lead level then dropped to 69.9 microg/dL. The patient received two subsequent courses of oral succimer and the blood lead level decreased to 59 microg/dL 21 days after the first course. The follow-up abdominal X-ray 20 days after the first examination was normal. Four months later, an outpatient follow-up visit showed a blood lead level within normal limits (14.5 microg/dL) and a psychiatric follow-up was initiated. Lead poisoning following the ingestion of lead-containing foreign bodies is particularly rare in adults, while it is sometimes observed in children. Pica behavior is a well-identified risk factor of lead intoxication in children but is quite exceptional in adults, where it is usually considered to be a psychiatric condition. Other unusual sources of lead poisoning include the ingestion of lead bullets, ceramic lead glaze or glazed earthenware, lead-contaminated candies, ethnic or herbal remedies. PMID:17906991

    Eleven patients from the West Bank village of Es-Sawiyeh were admitted with lead poisoning to two Jerusalem hospitals between November 1982 and January 1983. They all belonged to several households of a single large family. Colicky abdominal pains were present in five patients, weakness in four, behavioral changes ranging from irritability to frank psychosis in four, and paralysis in one. Anemia of various degrees was seen in all patients. Basophilic stippling and reticulocytosis were encountered in all patients with moderate to severe anemia. Therapy with edetate disodium calcium and penicillamine resulted in clinical improvement in all patients. A preliminary survey of 270 subjects in the same village disclosed 84 subjects with abnormally elevated blood lead levels, 17 of whom had grade IV lead burden according to the Centers for Disease Control risk classification. Contamination of homemade flour by lead used for stabilizing the metal parts of stone mills was the source of poisoning. As the method of milling in many West Bank villages is similar, these findings may have important implications to the well being of a large section of the rural West Bank population.

    To assess the risk of lead poisoning among preschool and school-aged children in Bangladesh, 345 children were screened for blood lead levels (BLLs) from one rural and two urban areas in Bangladesh from September 2007 through January 2008. An urban industrial area at Tongi was identified as a disaster area, where 99% (104/105) of those tested had BLLs >or= 10 microg/dL. Industrial emissions and use of leaded gasoline by two-stroke engine vehicles were identified as possible sources of lead in that area. A rural nonindustrial area at Chirirbandar, Dinajpur was identified as another high-risk area, where 14% of the children screened had BLLs >or= 10 microg/dL. BLLs at the urban industrial area were significantly higher than those at the rural and urban nonindustrial areas (24.58 +/- 10.32, 7.24 +/- 6.31, and 2.47 +/- 3.32 microg/dL, respectively; p <0.001). Weight-for-age z-scores of the urban children were significantly lower than that of the rural children (-1.41 +/- 1.88 vs. 0.20 +/- 1.16, p <0.001). Children with elevated BLLs had poorer nutritional status (p = 0.05) than those with normal BLLs. Over 90% of the parents did not know that lead causes health problems. In conclusion, the problem of lead poisoning in children was found to be high in both urban and rural Bangladesh. A universal lead screening for preschool and school-aged children and a lead education program for parents are recommended for implementation in Bangladesh.

In conclusion, the problem of lead poisoning in children was found to be high in both urban and rural Bangladesh. A universal lead screening for preschool and school-aged children and a lead education program for parents are recommended for implementation in Bangladesh.

    A 66-year-old man suffered the symptoms of severe lead poisoning for 2 years before diagnosis. The man had a blood lead level (PbB) on admission to hospital of 98 microg/dL. A detailed investigation revealed that the poisoning occurred as a result of drinking a homemade red wine, for which analyses showed a lead concentration up to 14 mg/L--70 times the Australian maximum limit for lead in wine. The source of the lead was a highly corroded enamel bathtub in which grape crushings and juice were stored for a week prior to bottling. The corrosion of the enamel surface of the bathtub had resulted in pitted patches up to 1 mm in depth along the side of the bathtub. Powdering of the tub surface was evident below a level where wine had been in contact with the sides of the tub. The homemade wine had a pH of 3.8, which would have greatly contributed to the solubilization of metals from the glaze. We conducted a test in which commercial red wine of similar pH and containing < 0.2 mg/L lead was placed in this tub for 7 days. Subsequent testing revealed a lead level of 310 mg/L. This high lead concentration is consistent with the surface area of enamel on the bathtub being in contact with a small liquid volume as in the case of the leaching test using commercial red wine. This case study highlights the importance of the use of food-grade materials for the preparation and storage of homemade beverages or food. PMID:11335194

  4. Chronic lead poisoning in steers eating silage contaminated with lead shot - diagnostic criteria

    Lead ingestion is one of the most common causes of poisoning in cattle. Toxicity results most commonly from the consumption of a single high dose of lead although cumulative toxicity resulting from the ingestion of small doses over a prolonged time also occurs. The sources of lead most commonly involved in disease outbreaks are paint, batteries, felt, linoleum and oil. It has traditionally been held that ingested metallic lead does not present a major toxicity risk to cattle because of its low solubility in the rumen and reticulum. More recent evidence suggests that lead shot, if present in silage, can induce toxicity when such silage is eaten by cattle. This communication describes a poisoning outbreak in steers eating lead shot contaminated grass silage. It presents and discusses the limitations of the criteria used for arriving at a diagnosis, including the use of whole blood amino levulinic acid dehydratase (ALAD) concentrations in fresh whole blood and after reactivation with dithiothreitol. Three are differences of opinion, in the literature, regarding the response of erythrocyte ALAD to ingested lead in the bovine. Consequently the results of a small lead feeding trial are also reported here. These results demonstrate a large ALAD response to lead ingestion and justify the use of this test in the confirmation of field cases of lead poisoning in cattle such as the one reported here.

    Full Text Available Recent research evidence suggests a central role for hepcidin in iron homeostasis. Hepcidin is a hormone synthesized in the liver. Hepcidin is also thought to play a vital role in the pathogenic mechanism of anaemia in patients with inflammation or chronic disease. A 38-year-old female who presented with recurrent abdominal pain was found to have raised urinary porphyrins and a blood lead level of 779 µg/l. Her haemoglobin level was 8.3 g/dl. Her MCV was normal. Serum ferritin, B12 and folate were normal. Her serum prohepcidin level was 2,489 ng/ml (normal <450 ng/ml . To our knowledge, this is the first report of raised prohepcidin levels in a patient with anaemia of chronic disease resulting from lead poisoning.

    We collected carcasses of 52 common eider Somateria mollissima adults and ducklings and blood samples from 11 nesting eider hens in the Gulf of Finland near Helsinki in 1994, 1995 and 1996. Samples of liver tissue were analysed for arsenic, cadmium, chromium, copper, iron, lead, magnesium, manganese, mercury, molybdenum, selenium and zinc. Blood was analysed for lead, mercury and selenium. Most of the 21 adults examined at necropsy were emaciated with empty gizzards, and no ingested shotgun pellets or other metal were found in any of the birds. Three adult females had a combination of lesions and tissue lead residues characteristic of lead poisoning. Two of these birds had acid-fast intranuclear inclusion bodies in renal epithelial cells and high concentrations of lead (73.4 and 73.3 ppm; all liver residues reported on dry weight basis) in their livers. The third was emaciated with a liver lead concentration of 47.9 ppm. An adult male had a liver lead concentration of 81.7 ppm, which is consistent with severe clinical poisoning. Two other adults, one male and one female, had liver lead concentrations of 14.2 and 8.03 ppm, respectively. Lead concentrations in the blood of hens ranged from 0.11 to 0.63 ppm wet weight. Selenium residues of A?60 ppm were found in the livers of five adult males. Selenium concentrations in the blood of hens ranged from 1.18 to 3.39 ppm wet weight. Arsenic concentrations of 27.5-38.5 ppm were detected in the livers of four adult females. Detectable concentrations of selenium, mercury and molybdenum were found more frequently in the livers of adult males arriving on the breeding grounds than in incubating females, while the reverse was true for arsenic, lead and chromium. Mean concentrations of selenium, copper and molybdenum were higher in the livers of arriving males than in the livers of incubating hens, but hens had greater concentrations of iron and magnesium. Concentrations of trace elements were lower in the livers of ducklings than

  8. Lead poisoning among household members exposed to lead-acid battery repair shops in Kingston, Jamaica.

    1989-12-01

    To investigate the risk of lead poisoning among household members exposed to 'backyard' battery repair shops (BBRS) in Kingston, Jamaica, environmental and blood lead (PbB) were measured at 24 households (112 individuals) with a BBRS worker or located at a BBRS premises and at 18 neighbourhood control households (74 individuals). Elevated PbB (greater than or equal to 25 micrograms per decilitre [micrograms/dl]) was common among subjects of all ages living at BBRS premises, especially among children less than age 12, 43% of whom had PbB greater than 70 micrograms/dl. Potentially hazardous soil and house dust lead levels were also common at BBRS premises, where 84% of yards had soil lead levels above 500 parts per million (geometric mean 3388 parts per million [ppm] at BBRS premises households with a BBRS worker). Geometric mean blood and environmental lead levels were significantly lower at control households, where less than 10% of subjects in all age groups had elevated PbB (maximum 33 micrograms/dl). Sharing a premises with a BBRS was a stronger determinant of household blood lead and environmental contamination than was the presence of a BBRS worker in a household. Blood lead levels were associated with soil and house dust lead levels in all age groups. We conclude that small battery repair shops, which have also been described in other developing countries, create a high lead poisoning risk for nearby residents.

    Childhood lead (Pb) poisoning remains a global issue, especially in industrial areas. In this study, 115 children with average age 5.7 years were recruited as either patient diagnosed with Pb poisoning or controls at Xinhua Hospital in China. The subjects' bone Pb was measured with a K-shell X-ray fluorescence (KXRF) and a portable X-ray fluorescence (XRF) system. A significant correlation between KXRF bone Pb and blood Pb and portable XRF and KXRF measurements were observed. The half-life of blood-lead was calculated to be 9.96 ± 3.92 d. Our results indicate that bone is a useful biomarker for Pb in children. PMID:26856822

    A doctor prescribed a dietary supplement prepared from powdered animal bone for a young woman with dysmenorrhea. Severe lead poisoning developed while she was taking the powder, which was shown to be contaminated with lead. The diagnosis eluded more than 20 physicians and was finally made by the patient herself. The Food and Drug Administration, informed of the contamination, declined to take action, stating that a food supplement is neither a food nor a drug and, besides, there are no maximal limits for heavy-metal contamination of foods and drugs.

    Meso-2,3-dimercaptosuccinic acid (DMSA, or succimer) is an oral chelating agent for heavy-metal poisoning. While studying the urinary elimination of unaltered DMSA, altered DMSA (i.e., its mixed disulfides), and lead in children with lead poisoning, we observed a pattern of urinary drug elimination after meals suggestive of enterohepatic circulation. The excretion of lead in urine patterned the elimination of altered DMSA rather than the parent molecule. In addition, the half-life of eliminat...

    2013-02-01

    Acute sickness involving dairy cattle (n = 5) with a morbidity of 100% occurred in a farm in Nakuru, Kenya. A case study was undertaken with the objective of establishing the cause of the sickness. Samples of blood, soil and industrial waste contained high levels of lead. The symptoms, results of postmortem and history of the case were used to establish the diagnosis of acute lead poisoning. This is a forensic case in court between the owner of the animals and a lead recycling company that dumped the industrial waste that was associated with the poisoning. There could be many unreported cases of lead poisoning in Kenya areas with heavy industrial activities since data on of lead poisoning in Kenya is scanty.

    This article reports on patient that has been presented with sudden onset of constipation, abdominal pain and normocytic anemia. Gastroscopy and colonoscopy ruled out an organic diseases. In peripheral blood and bone marrow aspirates mears, coarse basophilic stippling of erythrocyte (and erythroblasts) point out a possibility of heavy metal poisoning. The level of plumbemia exceeded 8.4 times the maximal permitted value for common (non-professional) population. A source of poisoning was indentified from a glaze on a ceramic jug, from which the patient had drank tea with lemon for three months. A lead concentration in the tea extract was 227 mg/kg. In developed countries, lead poisoning is a rare diagnosis. As the symptoms are nonspecific, missed diagnoses could occur, especially in sporadic, non-occupational exposure. However, a microscopic evaluation of the peripheral bloods mear with finding of predominantly coarse basophilic stippling of erythrocyte mayle ad to suspicion of lead poisoning. PMID:27172444

It was aimed to evaluate the effect of PBL scenario written on this topic on level of knowledge about childhood poisoning of third class students who completed the most of theoretical pharmacology education.Materials and Method: A questionnaire form prepared by researchers was applied to randomly chosen PBL groups without writing names and on the basis of voluntariness before and after a case of childhood poisoning which was applied as the second PBL scenario in the second midterm of 2009-2010 academic years. Numbers, percentages, chi-square and student’s t-test were used for evaluation of the questionnaire form comprised of demographic data, open-closed ended questions for measuring attitudes and level of knowledge against case of poisoning and statements as making a priority ranking.Results: In the study group, 89 students took part in pre-test and 96 students took part in post-test. In the answers to the list including the substances that are the most common causes of admission according to data of Refik Saydam National Poison Center (e.g. lotion, bath foam, cosmetics, water color and calamine lotions, the substances that the students stated to be toxic in pre-test were answered correctly in the post-test (p<0.05. Number of correct answers increased significantly for knowledge about commonly used drugs in clinical practice like anti-depressants, calcium canal blockers, oral antidiabetics that were marked as non-toxic by the students although they are toxic (p<0.05. While mean knowledge score for these 40 items was 17.52±5.82 in pre-test, it increased to 27.89±8.79 in post-test (p<0.001.Conclusion: Results of this study indicate that PBL scenario applied to the students who learned pharmacology

  3. Deaths related to lead poisoning in the United States, 1979-1998

    International Nuclear Information System (INIS)

    This study was conducted to describe trends in US lead poisoning-relate deaths between 1979 and 1998. The predictive value of relevant ICD-9 codes was also evaluated. Multiple cause-of-death files were searched for record containing relevant ICD-9 codes, and underlying causes and demographic characteristics were assessed. For 1979-1988, death certificates were reviewed; lead source information was abstracted and accuracy of coding was determined. An estimated 200 lead poisoning-related deaths occurred from 1979 to 1998. Most were among males (74%), Blacks (67%), adults of age ≥45 years (76%), and Southerners (70%). The death rate was significantly lower in more recent years. An alcohol-related code was a contributing cause for 28% of adults. Only three of nine ICD-9 codes for lead poisoning were highl predictive of lead poisoning-related deaths. In conclusion, lead poisoning-related death rates have dropped dramatically since earlier decades and are continuing to decline. However, the findings imply that moonshine ingestion remains a source of high-dose lead exposure in adults

    2016-03-01

    Full Text Available Background: To investigate the risk factors of child lead poisoning in China. Methods: A document retrieval was performed using MeSH (Medical subject heading terms and key words. The Newcastle-Ottawa Scale (NOS was used to assess the quality of the studies, and the pooled odd ratios with a 95% confidence interval were used to identify the risk factors. We employed Review Manager 5.2 and Stata 10.0 to analyze the data. Heterogeneity was assessed by both the Chi-square and I2 tests, and publication bias was evaluated using a funnel plot and Egger’s test. Results: Thirty-four articles reporting 13,587 lead-poisoned children met the inclusion criteria. Unhealthy lifestyle and behaviors, environmental pollution around the home and potential for parents’ occupational exposure to lead were risk factors of child lead poisoning in the pooled analyses. Our assessments yielded no severe publication biases. Conclusions: Seventeen risk factors are associated with child lead poisoning, which can be used to identify high-risk children. Health education and promotion campaigns should be designed in order to minimize or prevent child lead poisoning in China.

  5. Occupational lead poisoning in Ohio: surveillance using worker's compensation data

    1986-11-01

    To determine the utility of workers' compensation (WC) data in a system for the surveillance of occupational lead poisoning, we reviewed workers' compensation claims for lead poisoning in Ohio. For the period 1979 through 1983, 92(81 per cent) of the 114 claims attributed to lead met our case definition of lead poisoning. The likelihood that a company had a case of lead poisoning was strongly correlated with the number of claims against the company. Thirty companies accounted for the 92 cases; two companies accounted for 49 per cent of these. Inspection by the Occupational Safety and Health Administration (OSHA) occurred at 14 of these companies, all of which were cited for violations of the OSHA lead standard. Comparison of the Standard Industrial Classification (SIC) codes for the 14 companies inspected by OSHA with the 15 companies not inspected by OSHA revealed that OSHA inspected battery manufacturers, non-ferrous foundries, secondary smelters, and primary lead smelters, but not bridge painters, manufacturers of electronic components, mechanical power transmission equipment, pumps, and paints, nor a sheriff's office where firing range slugs were remelted to make new bullets. Neither the number of cases of lead poisoning at a company nor the size of a company was related to the likelihood of being inspected by OSHA. Claims for WC appear to be useful adjunct to an occupational lead poisoning surveillance system; their usefulness should be compared to that of other systems such as laboratory reports of elevated blood lead levels in adults.

    The phase-out of leaded gasoline began in Jakarta, Indonesia on July 1, 2001. We evaluated mean blood lead levels (BLLs) and the prevalence of elevated BLLs of Jakarta school children and assessed risk factors for lead exposure in these children before the beginning of the phase-out activities. The study involved a population-based, cross-sectional blood lead survey that included capillary blood lead sampling and a brief questionnaire on risk factors for lead poisoning. A cluster survey design was used. Forty clusters, defined as primary schools in Jakarta, and 15 2nd- and 3rd-grade children in each cluster were randomly selected for participation in the study. The average age of children in this study was 8.6 years (range 6-12) and the geometric mean BLL of the children was 8.6 {mu}g/dl (median: 8.6 {mu}g/dl; range: 2.6-24.1 {mu}g/dl) (n=397). Thirty-five percent of children had BLLs {>=}10 {mu}g/dl and 2.4% had BLLs {>=}20 {mu}g/dl. Approximately one-fourth of children had BLLs 10-14.9 {mu}g/dl. In multivariate models, level of education of the child's primary caregiver, water collection method, home varnishing and occupational recycling of metals, other than lead, by a family member were predictors of log BLLs after adjustment for age and sex. BLLs of children who lived near a highway or major intersection were significantly higher than those of children who lived near a street with little or no traffic when level of education was not included in the model. Water collection method was a significant predictor of BLLs {>=}10 {mu}g/dl after adjustment for age and sex. BLLs in children in this study were moderately high and consistent with BLLs of children in other countries where leaded gasoline is used. With the phase-out of leaded gasoline, BLLs of children in Jakarta are expected to rapidly decline as they have in other countries that have phased lead out of gasoline.

  7. The cultural parameters of lead poisoning: A medical anthropologist's view of intervention in environmental lead exposure

    1990-11-01

    This article identifies four culturally shaped sources of lead exposure in human societies: modern and historic technological sources; food habits; culturally defined health beliefs; and beauty practices. Examples of these potential sources of lead poisoning are presented from current cultures. They include the use of lead-glazed cooking pottery in Mexican-American households; folk medical use of lead in Hispanic, Arabic, South Asian, Chinese, and Hmong communities; as well as the use of lead as a cosmetic in the Near East, Southeast Asia, and South Asia. Four interacting cultural conditions that create barriers to the reduction of lead exposure and lead poisoning are identified and discussed. These are knowledge deficiencies, communication resistance, cultural reinterpretations, and incongruity of explanatory models.

    Following the discovery of severe lead poisoning in members of several households in a West Bank village, studies were carried out to establish the magnitude of the problem in the community and to identify the source of lead poisoning. Forty-three patients with Centers for Disease Control risk group IV lead poisoning were identified and treated in three villages within a radius of about 10 km of each other. The prevalence of increased lead burden among 563 schoolchildren aged 10 to 18 years was 19% for Centers for Disease Control risk groups I and II and 11% for groups III and IV. A survey of potential sources excluded all items, except for locally ground flour, which was heavily contaminated in all affected households. Examination of community flour mills revealed that, in contrast to unprocessed grain, freshly ground flour contained large amounts of lead originating from lead fillings employed to fasten the housing of the driveshafts to the millstones. Systematic screening of 146 community stone mills in 92 West Bank villages showed significant lead contamination of flour in 33 mills (23%). In all cases, the source of lead contamination was identical. As methods of milling in the area are similar, a prompt investigation of this potential source of lead poisoning in other near-Eastern countries is indicated.

  9. The lead-poisoned genius: saturnism in famous artists across five centuries.

    Lead poisoning (saturnism) has been present throughout the history of mankind. In addition to possible ingestion from contaminated food, one of the most important ways in which poisoning caused morbid processes was by occupational exposure. This exposition was pandemic in the Roman Empire, and it has been claimed that it contributed to its fall, but it also caused numerous epidemics in Western countries until the nineteenth century. In the case of artists, and since the Renaissance period, this toxicity has been called painter's colic or painter's madness. The latter term is partly due to the mental disorders displayed by some of the great masters, including Michelangelo and Caravaggio, although it was long recognized that even house and industrial painters were prone to the disorder. This chapter examines the historical evidence of recognition of such toxicity and discusses the controversies raised by the possibility of professional lead poisoning in great artists. In addition to those mentioned above, many other artists across several centuries will be discussed, some being Rubens, Goya, Fortuny, Van Gogh, Renoir, Dufy, Klee, Frida Kahlo, and Portinari. This chapter also briefly mentions the possibility of lead poisoning in two famous composers: Beethoven and Handel. Whether suffering from lead poisoning or not, about which we cannot always be sure, we should still highlight and admire such geniuses fighting their disorders to bequeath us their immortals works.

    The Coeur d'Alene River basin in Idaho has been contaminated by mine tailings that have impaired the health of wildlife since the early 1900s. In other parts of the world, virtually all lead poisoning of waterfowl is caused by the ingestion of manmade lead artifacts, primarily spent lead shotshell pellets or, occasionally, fishing sinkers. However, in the Coeur d'Alene River basin in Idaho, nonartifactual lead poisoning was the ultimate cause of death of most of 219 (77%) of 285 waterfowl carcasses that had been found sick or dead from 1992 through 1997. The majority of these 219 waterfowl (172 tundra swans [Cygnus columbianus], 33 Canada geese [Branta canadensis], and 14 other species) were poisoned by ingesting river sediment that was contaminated with lead. The next most common cause of death (20 instances, 7%) was lead poisoning accompanied by ingested shotshell pellets. The remaining 46 waterfowl succumbed to trauma, infectious diseases (aspergillosis, avian cholera, tuberculosis), or miscellaneous problems, or the cause of death was not determined.

    Lead is a major public health issue. Its use has been increasing since Neolithic times, climaxing in the Ancient Rome and the nineteenth century. Defining the frequency of plumbism before modern times proves to be a difficult matter because of its various and delayed symptoms, and of diagenetic processes affecting bones. After reviewing various methods of lead measurement in bone and tooth, we will expose ways to ascertain lead measurement interpretation in order to estimate the epidemiology of plumbism in ancient times.

    eventos tóxicos na infância, respectivamente.OBJECTIVE: To investigate whether the lack of knowledge of toxic agents in households is a risk factor for individual unintentional childhood poisoning. METHODS: The case group (n = 25 was composed of caregivers of children under 60 months of age who underwent accidental oral poisoning and were treated at two reference hospitals in Porto Alegre, southern Brazil, and recorded in the Toxicology Information Center database. The control group (n = 25 was composed of caregivers of children matched for sex, age, and presence in their homes of the same toxic agents found in the case group, who sought emergency medical care at the same hospitals, but for other reasons. A structured questionnaire was administered to verify the following questions: sociodemographic data, clinical history, behavioral antecedents of caregivers, storage of toxic agents, history of previous poisoning accidents. RESULTS: The children's mean age was 31.8 months (±0.97 and mean height was 93 cm (±11. Families, in both groups, were aware of the toxic action of agents available in their homes; however, caregivers in the control group were twice as likely to have such knowledge compared to the case group. Distraction was 15 times more likely to occur among caregivers of children who underwent poisoning compared to the control group. Storage of toxic agents below 150 cm was approximately 17 times more likely to occur in the group of children who underwent poisoning compared to children in the control group. CONCLUSIONS: Lack of knowledge of the toxic action of agents stored in households is not a risk factor for childhood poisoning. The attributable risks described in this study indicated that the elimination of other factors, such as distraction and storage below 150 cm, would lead to the prevention of 13 and 19% of poisonings in childhood, respectively.

    Objective To define the prevalence, severity and risk factors for lead poisoning in new immigrant children from the mainland of China to Hong Kong, China.Methods New immigrant children from the mainland of China under 18 years of age were invited to join the study. Their growth parameters and venous blood lead levels (BLL) were measured within 7 days of arrival. Those with elevated BLL i.e. >10?μg/dl (0.48?μmol/L) were assessed for signs, symptoms and risk factors of lead poisoning. Education on the prevention of lead poisoning and follow up BLL measurements were offered until their BLL normalized.Results Four hundred and fifty-seven children were recruited. Among them, 18.1% and 2.6% had BLL >0.48 and 0.71?μmol/L, respectively. None had BLL >0.96?μmol/L. Possible risk factors included contaminated drinking water (19%), herb ingestion (17.5%), pica, playing in dumping grounds, residing near paint factories or highways, habitual inhalation of car exhaust and cooking with petroleum. Symptoms and signs included abdominal pain, headache, short stature, and learning difficulties but did not correlate with BLL. None required treatment except for counseling on the avoidance of risk factors. About 94.7% showed a reduction in BLL 2-3 months after arrival and before counseling. All had normalized BLL by 9 months except 1 who had an X-ray feature of lead line.Conclusions Lead poisoning is common in new immigrant children from the mainland of China. Environmental factors were most important while behavioral factors like regular herb ingestion might have contributed to the persistence of high BLL in the minority.

  19. Using the current Brazilian value for the biological exposure limit applied to blood lead level as a lead poisoning diagnostic criterion

    1996-01-01

    Full Text Available In general, biological exposure limits are only used for the promotion and preservation of workers' health and are not applied for diagnostic purposes. However, the issue is controversial for certain types of occupational poisoning. This paper proposes the utilization of biological exposure limits currently applied to blood lead levels in Brazil as an important criterion for diagnosing occupational lead poisoning. The author argues that contrary to the traditional clinical criterion, one should deal with the diagnostic problem of lead poisoning from an epidemiological perspective, using the current Brazilian value for the biological exposure limit applied to blood lead level as an indicator of high relative risk.

    Low-level lead poisoning is an insidious disease that affects millions of children worldwide, leading to biochemical and neurological dysfunctions. Blocking lead uptake via the gastrointestinal tract is an important prevention strategy. With this in mind, we constructed the recombinant Lactococcus lactis strain pGSMT/MG1363, which constitutively expressed the fusion protein glutathione S-transferase (GST)-small molecule ubiquitin-like modifier protein (SUMO)-metallothionein-I (GST-SUMO-MT). The thermodynamic data indicated that the average number of lead bound to a GST-SUMO-MT molecule was 3.655 and this binding reaction was a spontaneous, exothermic and entropy-increasing process. The total lead-binding capacity of pGSMT/MG1363 was 4.11 ± 0.15 mg/g dry mass. Oral administration of pGSMT/MG1363 (1 × 10(10) Colony-Forming Units) to pubertal male rats that were also treated with 5 mg/kg of lead acetate daily significantly inhibited the increase of blood lead levels, the impairment of hepatic function and the decrease of testosterone concentration in the serum, which were all impaired in rats treated by lead acetate alone. Moreover, the administration of pGSMT/MG1363 for 6 weeks did not affect the serum concentration of calcium, magnesium, potassium or sodium ions. This study provides a convenient and economical biomaterial for preventing lead poisoning via the digestive tract. PMID:27045906

    Young children who are enrolled in Medicaid or the Children’s Health Insurance Program (CHIP) can be at risk for developing early childhood caries (ECC). ECC is a chronic bacterial infection that causes severe tooth decay and can begin to develop before baby teeth erupt. Children with ECC may experience pain, difficulty eating, developmental complications, and loss of days in day care or preschool. ECC is expensive to treat and untreated ECC can lead to other serious infections.

    Objectives To investigate the blood lead level in children aged 0-6 years in urban areas of China. Methods Fourteen cities were selected as sites under surveillance. A total of 44 045 peripheral blood specimens were collected from 2004 to 2006, during which 15 727, 14 737, and 13 584 specimens were tested in 2004, 2005, and 2006, respectively. Tungsten atomizer absorption spectrophotometer was employed to determine blood lead level. Results The geometric mean blood lead level in the tested children was 47.10μg/L with 10.10% ≥100μg/L, 46.17μg/L with 7.78%≥100μg/L, and 47.03μg/L with 7.30% ≥ 100μg/L in 2004, 2005, and 2006, respectively. The blood lead levels seemed to tend to rise in parallel with the increase of age of the children and were higher in boys (48.84μg/L, 47.56μg/L, and 47.78μg/L in the 3 respective years) than in girls (45.00 μg/L 44.53μg/L, and 46.13μg/L). Conclusion The blood lead levels in children in cities of China are lower than those in previous national studies, but higher than those in developed countries. Childhood lead poisoning remains a public health problem in China.

    Full Text Available OBJECTIVE: To estimate the prevalence of lead poisoning in children and to identify associated factors, as well as possible local sources of contamination. METHODS: A cross-sectional prevalence study conducted in 2006 with a random sample of 97 children age zero to five years from a neighborhood in Porto Alegre, Southern Brazil. Blood lead levels were measured and a questionnaire administered to collect information on sociodemographics, recycling and dwelling. A preliminary environmental evaluation was carried out with direct analysis of soil and indirect analysis of air pollution with bioindicators to identify possible sources of contamination. To analyze lead concentrations from the different collection sites, for each type of material studied, ANOVA was performed with a Brown-Forsythe adjustment for heteroscedasticity and with Dunnett's T3 procedure for multiple comparisons of unequal variances. RESULTS: Blood lead levels > 10.0 µg/dL was found in 16.5% of children. Recycling of waste at home, low father's education level, and increased age of children were associated with increase blood lead levels. High lead levels were found in soil, and there was little indication of lead air pollution. CONCLUSIONS: A high prevalence of lead poisoning was identified, and the potential sources of contamination in this community appear related to waste recylcing activities. Studies should be conducted with other populations of Brazilian children and evaluate potential sources of local and general contamination, to accurately characterize this issue in Brazil.

    The exposition to lead in the Antiquity is one of the first environmental health risks in the history of the mankind. In the ancient cultures of Egypt, Crete and Sumer there was no reports of an important exposition to this metal. The first clinical data is described in the Corpus Hipocraticcus, however was Nicandrus of Colophon the first to make a thorough description of the clinical manifestations of this disease. There was an increase in the exposition to this metal in times of the Roman empire and even some researchers propose that Julius Cesar and Octavio had clinical manifestations associated with lead poisoning. Paul of Aegina in the 7th century (a.C.) describes the first epidemic associated with lead intoxication, however in the Middle Ages the use of lead decrease until the Renaissance period in which lead poisoning affects mostly painters, metal-smithers and miners. Some studies done in the ice-layers of Greenland showed that the environmental pollution by lead during the Roman empire and the Renaissance was important.

    Full Text Available OBJECTIVES: It was considered that lead isotope ratios did not change during physical, chemical, or biological processes. Thus, lead isotope ratios have been used as fingerprints to identify possible lead sources. However, recent evidence has shown that the lead isotope ratios among different biological samples in human are not always identical from its lead origins in vitro. An animal experiment was conducted to explore the biological fractionation of lead isotopes in biological systems. METHODS: 24 male Sprague-Dawley (SD rats were divided into groups that received acute lead exposure (0, 0.02, 0.2, or 2 mg/kg body weight of lead acetate via the respiratory route every day for 5 days. Biological samples (i.e., blood, urine, and feces were collected for comparison with the lead acetate (test substance and the low-lead animal feed (diet administered to the rats. The lead isotope ratios were determined by inductively coupled plasma mass spectrometry (ICP-MS. RESULTS: There are significant differences (p<0.05 in lead isotope ratios between blood, urine, and feces. Moreover, a nonlinear relationship between the blood lead concentration and the blood lead isotope ratios was observed. There is also a threshold effect to the fractionation function. Only the blood isotope ratio of (204Pb/(206Pb matches the test substance well. As for feces, when (204Pb/(206Pb ratio is considered, there is no significant difference between feces-test substance pairs in medium and high dose group. CONCLUSIONS: The biological fractionation of lead isotopes in SD rats was observed. Moreover, there might be a threshold for the biological fractionation of lead isotopes which is depending on whole blood lead level. It is considered to be more reliable that we compared the isotope ratios of potential lead hazards with both blood and feces lead fingerprints especially for (204Pb/(206Pb ratio under high-dose exposure.

    Abstract Background: Lead is a toxic element of the environment which leads to major complications once it enters the blood stream, affecting multiple organs and systems of the body. Methods: We present the case of a 16-year-old girl, diagnosed with lead poisoning after occupational exposure due to the fact that the girl was actively involved in the family's pottery business. History revealed that the girl participated in the process of pottery, her father was also diagnosed with lead poisoning 2 years before. The patient's personal history underlined that approximately 1 year ago she presented with severe abdominal pain, being diagnosed with acute appendicitis and she underwent appendectomy, but the pain persisted, thus due to family history of lead poisoning, the suspicion of saturnine colic rose, and she was diagnosed with lead poisoning. The main symptoms and signs were severe abdominal pain, vomiting, and arterial hypertension. The clinical evolution was favorable under symptomatic treatment and chelation therapy. Results: Lead toxicity is a life-threatening condition because of its severe acute and chronic complications. In children, there is no safe blood lead level, prevention methods are, therefore, very important in order to avoid toxic multiorganic effects of this metal. Conclusion: Even though the diagnosis of lead poisoning remains difficult in children, it must also be taken into consideration by the clinician facing a child with gastrointestinal or neurological involvement.

Even with the decrease in manufactured items produced with lead, contaminants persist in the landscape and may enter the food supply through animal products. Changing patterns of open range herds moving to new pasture and the increased popularity of urban/suburban backyard chickens or other livestock necessitates public awareness about the clinical signs of lead intoxication, the potential for subclinical animals, public health concerns, particularly for exposure in children, and testing options available. Cases of lead intoxication in livestock demand a thorough case work-up to identify all sources of lead, address subclinical cases, evaluate risk to consumers, and make management suggestions for future prevention. We discuss four recent cases of confirmed lead poisoning in backyard chickens and open range cattle and assess the public health implications therein. Taken as a whole and considering the potential of the remaining herd or flock to be affected without necessarily showing signs, public health officials and veterinarians should be prepared to advise clients on case work-up and management and prevention considerations. Backyard chickens and cattle may not present for suspected lead poisoning as in several of the cases discussed herein yet may still contain concerning tissue or blood levels.

    A study was made of 160 lead exposed workers at a secondary lead smelter, a small scrap smelter, and a lead chemicals facility to investigate dose response relationships between blood lead levels and toxic effects. The levels of blood lead ranged from 0.77 to 13.51 micromoles/liter (micromol/l). In 70 workers, 44 percent of the total number, clinical evidence of toxic exposure was detected including colic in 33, wrist or ankle extensor muscle weakness in 12, anemia in 27, elevated blood urea nitrogen (BUN) in 28, and possible encephalopathy in two. At blood lead levels below 1.93 micromol/l no toxicity was detected. However, 13 percent of those workers with blood lead levels of 1.93 to 3.81 micromol/l had extensor muscle weakness or gastrointestinal symptoms. In 5 percent of the workers with lead levels of 1.93 to 2.85 micromol/l, anemia was noted. Anemia was also noted in 14 percent with levels between 2.90 and 3.81 micromol/l and in 36 percent with levels over 3.86 micromol/l. In long term lead workers elevated BUN occurred. All but three workers with elevated BUN had at least 4 years of occupational lead exposure, and nine had received oral chelation therapy. Eight of this group had reduced creatinine clearance and eight had decreased renal concentrating ability.

    Lead (Pb) is a metabolic poison that can negatively influence biological processes, leading to illness and mortality across a large spectrum of North American avifauna (>120 species) and other organisms. Pb poisoning can result from numerous sources, including ingestion of bullet fragments and shot pellets left in animal carcasses, spent ammunition left in the field, lost fishing tackle, Pb-based paints, large-scale mining, and Pb smelting activities. Although Pb shot has been banned for waterfowl hunting in the United States (since 1991) and Canada (since 1999), Pb exposure remains a problem for many avian species. Despite a large body of scientific literature on exposure to Pb and its toxicological effects on birds, controversy still exists regarding its impacts at a population level. We explore these issues and highlight areas in need of investigation: (1) variation in sensitivity to Pb exposure among bird species; (2) spatial extent and sources of Pb contamination in habitats in relation to bird exposure in those same locations; and (3) interactions between avian Pb exposure and other landscape-level stressors that synergistically affect bird demography. We explore multiple paths taken to reduce Pb exposure in birds that (1) recognize common ground among a range of affected interests; (2) have been applied at local to national scales; and (3) engage governmental agencies, interest groups, and professional societies to communicate the impacts of Pb ammunition and fishing tackle, and to describe approaches for reducing their availability to birds. As they have in previous times, users of fish and wildlife will play a key role in resolving the Pb poisoning issue.

    Full Text Available Abstract Amongst toxic heavy metals, lead ranks as one of the most serious environmental poisons all over the world. Exposure to lead in the home and the workplace results in health hazards to many adults and children causing economic damage, which is due to the lack of awareness of the ill effects of lead. We report the case of a 22 year old man working in an unorganized lead acid battery manufacturing unit, complaining about a longer history of general body ache, lethargy, fatigue, shoulder joint pain, shaking of hands and wrist drop. Patient had blue line at gingivodental junction. Central nervous system (CNS examination showed having grade 0 power of extensors of right wrist & fingers. Reflexes: Supinator- absent, Triceps- weak and other deep tendon reflexes- normal. Investigations carried out during the admission showed hemoglobin levels of 8.3 g/dl and blood lead level of 128.3 μg/dl. The patient was subjected to chelation therapy, which was accompanied by aggressive environmental intervention and was advised not to return to the same environmental exposure situation. After repeated course of chelation therapy he has shown the signs of improvement and is on follow up presently.

    Some of the adverse effects of lead (Pb) may be associated with oxidative damage of lipids, proteins or DNA. In a previous study a linkage was observed between the susceptibilities of waterfowl species to Pb poisoning with oxidative stress. To investigate this relationship among the individuals of a single species, four groups of 12 mallards were fed for three weeks diets containing high or low levels of vitamin E (20 or 220 UI/kg) and high or low levels of Pb (0 or 2 g/kg). During the first week of Pb exposure, mallards developed hemolytic anemia, and during the second week, signs of neurological impairment. Histological findings in the Pb exposed mallards were hemosiderosis, demyelinization of sciatic and brachial nerves, and tumefaction of renal tubular epithelium with the presence of intranuclear inclusion bodies. Lipid peroxidation increased with Pb exposure in blood, liver, bile and brain, but decreased in nerves. Glutathione (GSH) increased with Pb exposure in liver and bile, and its oxidized/reduced ratio only increased in bile. Pb exposure inhibited GSH peroxidase activity (GPX) in plasma, liver and brain, and decreased protein thiols (PSH) in blood and liver. Vitamin E significantly prevented lipid peroxidation in nerves, but did not alleviate any sign of Pb poisoning. Pb-induced pathological changes associated with hepatic and nervous functions were significantly correlated with lower GPX activity and PSH concentrations in these tissues rather than lipid peroxidation. Data suggest that inhibition of antioxidant enzymes and interaction with sulfhydryl groups of proteins may play a more important role in Pb poisoning of waterfowl than lipid peroxidation.

    Comparative study is presented of adrenocortical dysfunction in workers chronically exposed to aromatic nitro compounds and to lead. The chronic intoxications produced by aromatic nitro compounds and by lead are characterized by a slight reduction in adrenocortical activity, which plays an important part in the pathogenesis of certain syndromes such as asthenia, gastric secretion disorders, lead anemia and lead polyneuritis. It is desirable to take measures to normalize corticosteroid formation when chronic occupational poisoning is being treated. (CIS Abstr. Vol. 2)

Con este caso clínico pretendemos revisar los síntomas del cuadro clínico de saturnismo, así como hacer una reflexión sobre los efectos de la prevención de riesgos para el trabajador.Lead poisoning is most commonly caused by occupational exposure. We report a case of a 65-year-old woman, paint teacher, which was working in reparation of stained glass window. She consults the Medical Incapacity Valoration Unit of National Institute of Social Security with diagnosis of lead occupational intoxication. The patient was not able to word for several months because of presenting asthenia. After reporting for work high lead blood levels were detected, in association with physical symptoms. She was evaluated by a tribunal which settled total long sick-leave due to occupational lead exposure and was restricted for loud works and other ones that need verbal communication in conversational frequencies. With this clinical case we try to check the symptoms of lead poisoning, as well as to think about the effects of prevention of occupational hazards.

    Full Text Available Introduction: During the treatment of Roma children from Kosovska Mitrovica suffering from chronic lead poisoning (which began in the second half of the last decade, hypertension has also been observed. The examination and treatment were conducted under the patronage of World Health Organization, Ministry of Health of the Republic of Serbia and local administration. Aim of this work is show correlation between lead levels in blood and hypertension in children. Materials and methods: Lead from capillary blood flow was measured by Lead care analyzer. Extracted blood from a vein measured lead level in the toxicological laboratory of the Institute „Karajovic“ Belgrade. The pressure was measured by standard devices with changeable cuffs and has been expressed in mmHg. Hypertension has been observed in 159 children. They were divided into four groups. First group: non-Roma children (n = 32 with blood lead level of up to 10 mcg/dl. Second group: Roma children (n = 31 with blood lead level of up to 10 mcg/dl. Third group: Roma children (n = 53 with blood lead levels of 10–45 mcg/dl. Fourth group: Roma children (n = 43 with blood lead levels more than 45 mcg/dl, with an average value of 61.6 mcg/dl. Results: There is a statistically significant difference in the elevation of systolic blood pressure between group (chi-square = 31,179; p < 0,001, the first (x = 107,2 mmHg and the fourth group (x =114,6 mmHg, the second (x = 104,5 mmHg and fourth group, third (x =106,4 mmHg and fourth group. There is a statistically significant difference in the elevation of diastolic blood pressure between group (chi-square = 32,028; p < 0,001, the first (x = 67,7 mmHg and the fourth group (x =73,4 mmHg, the second (x = 66 mmHg and third group (x = 69 mmHg, second and fourth group, third and fourth group of children. It is concluded that when the value of lead in the blood was higher its effect on blood pressure was more pronounced. Conclusion: Most children with

    Full Text Available Lead (Pb poisoning has always been a serious health concern, as it permanently damages the central nervous system. Chronic Pb accumulation in the human body disturbs oligodendrocytes (OLs differentiation, resulting in dysmyelination, but the molecular mechanism remains unknown. In this study, Pb at 1 μM inhibits OLs precursor cells (OPCs differentiation via decreasing the expression of Olig 2, CNPase proteins in vitro. Moreover, Pb treatment inhibits the sodium/calcium exchanger 3 (NCX3 mRNA expression, one of the major means of calcium (Ca2+ extrusion at the plasma membrane during OPCs differentiation. Also addition of KB-R7943, NCX3 inhibitor, to simulate Pb toxicity, resulted in decreased myelin basic protein (MBP expression and cell branching. Ca2+ response trace with Pb and KB-R7943 treatment did not drop down in the same recovery time as the control, which elevated intracellular Ca2+ concentration reducing MBP expression. In contrast, over-expression of NCX3 in Pb exposed OPCs displayed significant increase MBP fluorescence signal in positive regions and CNPase expression, which recovered OPCs differentiation to counterbalance Pb toxicity. In conclusion, Pb exposure disturbs OLs differentiation via affecting the function of NCX3 by inducing intracellular calcium overload.

    Full Text Available Whilst lead poisoning in raptors, scavenging birds and waterfowl is well studied and common knowledge, there is surprisingly little literature detailing the risk to mammalian scavengers and captive carnivores fed hunted meat. This case report describes the death of two captive cheetahs (Acinonyx jubatus jubatus following acute onset of nervous symptoms. Clinical signs included hyper-excitability, seizures, arched back, tail held abnormally high and hyper-salivation. Necropsy findings included bullets or a bullet in their stomachs. Kidney and liver lead levels from one cheetah (15.6 ppm and 17 ppm respectively were consistent with a diagnosis of lead poisoning; liver from the second cheetah was not available for testing. Both animals were routinely fed hunted antelope or game birds. This is the first report of oral lead poisoning in captive large carnivores, although these are unlikely to be the first cases. Without awareness of the risks of feeding hunted game, lead exposure will continue to be an underdiagnosed reality in the rehabilitation of endangered carnivores.

    The hippocampus, a major component of the brain, is one of the target nervous organs in lead poisoning. In this work, a rat's hippocampal injury caused by lead was studied. The lead concentrations in blood, bone and hippocampus collected from rats subject to lead poisoning were quantified by Inductively Coupled Plasma Mass Spectrometry while morphological information and elemental distributions in the hippocampus were obtained with synchrotron radiation X-ray phase contrast imaging and synchrotron radiation micro-beam X-ray fluorescence, respectively. For comparison, identical characterization of the specimens from the rats in the control group was done in parallel. Results show that the ratios between the lead content in the treated group and that in the control group of the hippocampus, bone, and blood are about 2.66, 236, and 39.6, respectively. Analysis also revealed that some health elements such as S, K, Cl and P increase in the regions with high lead content in the treated hippocampus. Morphological differences between the normal and lead-exposed hippocampus specimens in some local areas were observed. Explicitly, the structure of the lead-exposed hippocampus was tortuous and irregular, and the density of the neurons in the Dentate Gyrus was significantly lower than that from the control group. The study shows that the synchrotron radiation methods are very powerful for investigating structural injury caused by heavy metals in the nervous system.

    Lead poisoning still occurs in the United States despite extensive prevention efforts and strict regulations. Exposure to lead can damage the brain, kidneys, and nervous and reproductive systems. Fetal exposure to lead can adversely affect neurodevelopment, decrease fetal growth, and increase the risk for premature birth and miscarriage. During 2011-2012, the New York City Department of Health and Mental Hygiene (DOHMH) investigated six cases of lead poisoning associated with the use of 10 oral Ayurvedic medications made in India. All six cases were in foreign-born pregnant women assessed for lead exposure risk by health-care providers during prenatal visits, as required by New York state law. Their blood lead levels (BLLs) ranged from 16 to 64 µg/dL. Lead concentrations of the medications were as high as 2.4%; several medications also contained mercury or arsenic, which also can have adverse health effects. DOHMH distributed information about the medications to health-care providers, product manufacturers, and government agencies in the United States and abroad, via postal and electronic mail. DOHMH also ordered a local business selling contaminated products to cease sales. Health-care providers should ask patients, especially foreign-born or pregnant patients, about any use of foreign health products, supplements, and remedies such as Ayurvedic medications. Public health professionals should consider these types of products when investigating heavy metal exposures and raise awareness among health-care providers and the public regarding the health risks posed by such products.

  5. Bio-toxicological supervision op workers exposed to lead poisoning hazard. Systematic examination of amino acids, in urine and plasma

    International Nuclear Information System (INIS)

    A bio-toxicological chart was established for the workers in a firm handling lead. The known facts concerning professional lead poisoning are outlined, after which the importance of lead work in a nuclear center is discussed. The work station of each man is described and the results of analyses made during atmospheric checks on the site are given with sampling techniques. Since the biological chart is centered on the chromatographic exploration of amino acids in blood and urine, the analytical technique used is described and the different technical modifications made to the standard technique reported. The results obtained on reference subjects are compared with those found in the specialized literature. The results found in lead workers are then presented in the form of histograms, which better illustrate the differences observed with respect to the reference subjects. An hematological and toxicological balance-sheet is drawn up and the correlation existing between the results of coproporphyrine, lead and delta-aminolevulinic acid analyses in urine is checked. Biological detection of lead-poisoning has the advantage of providing an early diagnosis, thus enabling the works doctor to forestall the effects of this professional disease before any clinical symptoms appear.

  6. Childhood lead exposure and uptake in teeth in the Cleveland area during the era of leaded gasoline

    International Nuclear Information System (INIS)

    Childhood uptake of lead from exposure to atmospheric leaded gasoline in the United States has been studied using mainly blood lead levels. Since reliable blood lead techniques were used only after the peak use of leaded gasoline, the prior exposure history is unclear. The well-documented decline in blood lead levels after the mid-1970s could represent the continuation of a historic steady decline in exposure from many sources. Alternatively, the post-1970s decline might represent the declining phase of a unimodal rise and fall corresponding closely to usage of leaded gasoline. To assess these possibilities, lead concentration and 207Pb/206Pb isotope ratios were measured in the enamel of permanent molar teeth formed between 1936 and 1993 in mainly African-American donors who grew up in the Cleveland area. Tooth enamel preserves the lead concentration and isotope ratio that prevails during tooth formation. Historical trends in enamel lead concentration were significantly correlated with surrogates of atmospheric lead exposure: lead in sediments of two dated Lake Erie cores, and lead consumed in gasoline. About two-thirds of the total lead uptake into enamel in this period was attributable to leaded gasoline, and the remainder to other sources (e.g. paint). Enamel 207Pb/206Pb isotope ratios were similar to those of one lake sediment. Multivariate analysis revealed significant correlation in neighborhoods with higher levels of traffic, and including lake sediment data, accounted for 53% of the variation in enamel lead levels. Enamel lead concentration was highly correlated with reported African-American childhood blood levels. The extrapolated peak level of 48 μg/dL (range 40 to 63) is associated with clinical and behavioral impairments, which may have implications for adults who were children during the peak gasoline lead exposure. In sum, leaded gasoline emission was the predominant source of lead exposure of African-American Cleveland children during the latter

  7. Can Ingestion of Lead Shot and Poisons Change Population Trends of Three European Birds: Grey Partridge, Common Buzzard, and Red Kite?

    Carolyn B Meyer

    Full Text Available Little is known about the magnitude of the effects of lead shot ingestion alone or combined with poisons (e.g., in bait or seeds/granules containing pesticides on population size, growth, and extinction of non-waterbird avian species that ingest these substances. We used population models to create example scenarios demonstrating how changes in these parameters might affect three susceptible species: grey partridge (Perdix perdix, common buzzard (Buteo buteo, and red kite (Milvus milvus. We added or subtracted estimates of mortality due to lead shot ingestion (4-16% of mortality, depending on species and poisons (4-46% of mortality reported in the UK or France to observed mortality of studied populations after models were calibrated to observed population trends. Observed trends were decreasing for partridge (in continental Europe, stable for buzzard (in Germany, and increasing for red kite (in Wales. Although lead shot ingestion and poison at modeled levels did not change the trend direction for the three species, they reduced population size and slowed population growth. Lead shot ingestion at modeled rates reduced population size of partridges by 10%, and when combined with bait and pesticide poisons, by 18%. For buzzards, decrease in mean population size by lead shot and poisons combined was much smaller (≤ 1%. The red kite population has been recovering; however, modeled lead shot ingestion reduced its annual growth rate from 6.5% to 4%, slowing recovery. If mortality from poisoned baits could be removed, the kite population could potentially increase at a rapid annual rate of 12%. The effects are somewhat higher if ingestion of these substances additionally causes sublethal reproductive impairment. These results have uncertainty but suggest that declining or recovering populations are most sensitive to lead shot or poison ingestion, and removal of poisoned baits can have a positive impact on recovering raptor populations that frequently

  9. Osteosclerotic metaphyseal dysplasia: a skeletal dysplasia that may mimic lead poisoning in a child with hypotonia and seizures

    International Nuclear Information System (INIS)

    We report the case of a 23-month-old male with hypotonia, developmental delay, and complex seizures. Radiographs revealed profound sclerosis of the metaphyses and epiphyses of the long and short bones in the extremities, with a unique pattern of distribution. Sclerosis also involved the anterior ribs, iliac crests, talus, and calcaneus. The skull and vertebral bodies appeared unaffected. Blood lead levels were normal. We believe that this constellation of clinical and radiographic abnormalities closely resembles osteosclerotic metaphyseal dysplasia (OMD) due to an autosomal recessive defect. Characteristic skeletal findings were instrumental in determining the diagnosis. OMD is a very rare sclerosing bone disorder, first described in 1993. The syndrome is characterized clinically by developmental delay of a progressive nature, hypotonia, elevated alkaline phosphatase, and late-onset spastic paraplegia. We encountered a young child with these neurologic symptoms who displayed sclerotic metaphyseal changes on hand radiographs obtained to determine the bone age. Lead poisoning, a known cause of metaphyseal sclerosis, was initially suspected. Careful analysis of the metaphyseal bone changes helped to distinguish this bone dysplasia from lead poisoning and other causes of metaphyseal sclerosis. (orig.)

    Full Text Available BACKGROUND: Childhood lead exposure is a purported risk factor for antisocial behavior, but prior studies either relied on indirect measures of exposure or did not follow participants into adulthood to examine the relationship between lead exposure and criminal activity in young adults. The objective of this study was to determine if prenatal and childhood blood lead concentrations are associated with arrests for criminal offenses. METHODS AND FINDINGS: Pregnant women were recruited from four prenatal clinics in Cincinnati, Ohio if they resided in areas of the city with a high concentration of older, lead-contaminated housing. We studied 250 individuals, 19 to 24 y of age, out of 376 children who were recruited at birth between 1979 and 1984. Prenatal maternal blood lead concentrations were measured during the first or early second trimester of pregnancy. Childhood blood lead concentrations were measured on a quarterly and biannual basis through 6.5 y. Study participants were examined at an inner-city pediatric clinic and the Cincinnati Children's Hospital Medical Center in Cincinnati, Ohio. Total arrests and arrests for offenses involving violence were collected from official Hamilton County, Ohio criminal justice records. Main outcomes were the covariate-adjusted rate ratios (RR for total arrests and arrests for violent crimes associated with each 5 microg/dl (0.24 micromol/l increase in blood lead concentration. Adjusted total arrest rates were greater for each 5 microg/dl (0.24 micromol/l increase in blood lead concentration: RR = 1.40 (95% confidence interval [CI] 1.07-1.85 for prenatal blood lead, 1.07 (95% CI 0.88-1.29 for average childhood blood lead, and 1.27 (95% CI 1.03-1.57 for 6-year blood lead. Adjusted arrest rates for violent crimes were also greater for each 5 microg/dl increase in blood lead: RR = 1.34 (95% CI 0.88-2.03 for prenatal blood lead, 1.30 (95% CI 1.03-1.64 for average childhood blood lead, and 1.48 (95% CI 1

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

    Juvenile rats fed a diet containing 1% lead acetate for 7 weeks, in addition to an impaired growth rate and renal function derangements, suffered malabsorption of glucose and certain amino acids, as assessed by an in vivo perfusion technique. The reduction in glucose absorption ranged between 10% and 31% when the carbohydrate was pumped in concentrations of 2-80 mM. This alteration was compatible with a noncompetitive type of transport inhibition. The intestinal absorption of glycine, lysine, and phenylalanine were, respectively, decreased 22, 18, and 15% when these amino acids were present at 1 mM levels. Sodium transport was severely reduced (57.6 +/- 17.9 (SEM) vs. 124.2 +/- 17.4 muEq/min-cm) and intestinal mucosa (Na+-K+)-ATPase was concomitantly lower in the lead-intoxicated rats (186.4 +/- 19.0 vs 268.4 +/- 29.8 nmol P/min-mg protein). However, this enzyme was not altered in liver and kidney. Furthermore, intestinal mucosa fructose-1,6-diphosphatase, succinic dehydrogenase, pyruvate kinase, and tryptophan hydroxylase were not different in experimental and control animals. These studies substantiate the presence of functional and biochemical abnormalities in the intestinal mucosa of young rats when fed substantial amounts of a soluble lead salt. It is, therefore, reasonable to accept the possibility that physiologic damage occurs in tissues directly subjected to high and persistent levels of a toxic agents, as it occurs in other organs, underscoring the parallelism between transport mechanisms at the renal and intestinal levels.

    Objective To evaluate the effectiveness of a lead-expelling food on expelling mineral matters and expelling lead from lead poisoning mice induced by acetate lead. Methods Seventy-five Kuming male mice weighted 18 - 22 g were randomly divided into five groups: negative control group, lead poisoning model group and three intervention groups fed with low, medium and high dosage of lead-expelling food. Deionized water was provided for the negative control group and 1.00 g/L lead acetate solution was provided for the lead-poisoning model group and three intervention groups freely. The lead-expelling food for the low, medium and high dose intervention groups was administrated intragastrically with 5-, 10- or 20-fold of the recommended dosage for human use (0. 60 g/kg BW). The general situation and body weight changes were observed in 30 days. The content of lead, calcium, iron, zinc and copper in blood, liver, femur, kidney and brain were determined. Results The lead content of liver, kidney and brain in low, medium and high-dose intervention groups were lower than those in the lead-poisoning model group (P < 0. 05 or P < 0. 01 ). The lead content of blood and femur in medium and high-dose intervention group were lower than those in lead-poisoning model group ( P < 0. 05 or P < 0. 01 ). The calcium of liver, zinc of brain, copper of kidney in low-, medium- and high-dose intervention group were higher than those in the lead-poisoning model group (P <0. 05or P < 0. 01 ). The calcium of blood, kidney and brain, the iron, zinc and copper of blood, the blood and copper of brain in middle- and high-dose intervention groups were higher than those in lead-poisoning model group (P < 0. 05 or P < 0. 01 ). Iron of femur in high-dose intervention group was higher than that in lead-poisoning model group ( P < 0. 05 ). Conclusion The lead-expelling food plays a role in promoting lead elimination from mice, and can improve calcium, iron, zinc and copper metabolism

    Full Text Available A 42-year-old man from Bhutan was admitted to the emergency department with a 5-day history of abdominal pain, nausea and vomiting. Enhanced abdominal CT scan was found negative, however laboratory tests showed hemolytic anemia and basophilic stippling which are often seen in lead and heavy metal poisoning. Additional tests revealed a high level of lead in blood and urine. The patient was administered a chelator treatment with rapid improvement of the symptoms. A detailed interview revealed that the patient had been taking daily Bhutanese traditional medicines to treat a Bell’s palsy from which he had been suffering for a few months. The analysis of these medicines confirmed the presence of a high level of lead.

    contaminated with Pb, Cd, and Zn from mining, milling and smelting. Metals have been dispersed heterogeneously throughout the District in the form of milled mine waste ('chat'), as flotation tailings and from smelters as aerial deposition or slag. This study was conducted to determine if the habitat has been contaminated to the extent that the assessment populations of wild birds are exposed to toxic concentrations of metals. American robins (Turdus migratorius), northern cardinals (Cardinalis cardinalis), and waterfowl had increased Pb tissue concentrations (p concentrations from reference birds, and the exposure of songbirds to Pb was comparable with that of birds observed at other sites severely contaminated with Pb. Mean activities of the Pb-sensitive enzyme delta-aminolevulinic acid dehydratase (ALAD) were decreased by >50% in red blood cells in these birds (p concentrations of Pb that have been associated with impaired biological functions and external signs of poisoning. Cadmium was increased in kidneys of songbirds (p concentrations in liver and kidney of waterfowl were significantly higher (p concentrations of Zn associated with mining in the District accounted for the pancreatitis previously observed in five waterfowl from the District. The District is the first site at which free-flying wild birds have been found to be suffering severe effects of Zn poisoning.

    Full Text Available Abstract Background Early life lead exposure might be a risk factor for neurocognitive impairment in adulthood. Objectives We sought to assess the relationship between early life environmental lead exposure and intellectual function in adulthood. We also attempted to identify which time period blood-lead concentrations are most predictive of adult outcome. Methods We recruited adults in the Boston area who had participated as newborns and young children in a prospective cohort study that examined the relationship between lead exposure and childhood intellectual function. IQ was measured using the Wechsler Abbreviated Scale of Intelligence (WASI. The association between lead concentrations and IQ scores was examined using linear regression. Results Forty-three adults participated in neuropsychological testing. Childhood blood-lead concentration (mean of the blood-lead concentrations at ages 4 and 10 years had the strongest relationship with Full-Scale IQ (β = -1.89 ± 0.70, p = 0.01. Full-scale IQ was also significantly related to blood-lead concentration at age 6 months (β = -1.66 ± 0.75, p = 0.03, 4 years (β = -0.90 ± 0.41, p = 0.03 and 10 years (β = -1.95 ± 0.80, p = 0.02. Adjusting for maternal IQ altered the significance of the regression coefficient. Conclusions Our study suggests that lead exposure in childhood predicts intellectual functioning in young adulthood. Our results also suggest that school-age lead exposure may represent a period of increased susceptibility. Given the small sample size, however, the potentially confounding effects of maternal IQ cannot be excluded and should be evaluated in a larger study.

    Full Text Available Introduction. Although lead paint and leaded gasoline have not been used in the US for thirty years, thousands of US children continue to have blood lead levels (BLLs of concern. Methods. We investigated the potential association of modeled air lead levels and BLLs ≥ 10 μg/dL using a large CDC database with BLLs on children aged 0–3 years. Percent of children with BLLs ≥ 10 μg/dL (2000–2007 by county and proportion of pre-50 housing and SES variables were merged with the US EPA's National Air Toxics Assessment (NATA modeled air lead data. Results. The proportion with BLL ≥ 10 μg/dL was 1.24% in the highest air lead counties, and the proportion with BLL ≥ 10 μg/dL was 0.36% in the lowest air lead counties, resulting in a crude prevalence ratio of 3.4. Further analysis using multivariate negative binomial regression revealed that NATA lead was a significant predictor of % BLL ≥ 10 μg/dL after controlling for percent pre-l950 housing, percent rural, and percent black. A geospatial regression revealed that air lead, percent older housing, and poverty were all significant predictors of % BLL ≥ 10 μg/dL. Conclusions. More emphasis should be given to potential sources of ambient air lead near residential areas.

    Full Text Available Introduction: The effects of lead on children's health have been widely studied. Aim: To analyze the correlation between the long latency auditory evoked potential N2 and cognitive P3 with the level of lead poisoning in Brazilian children. Methods: This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluations. We performed periodic surveys of the lead concentration in the blood and basic audiological evaluations. Furthermore, we studied the auditory evoked potential long latency N2 and cognitive P3 by analyzing the absolute latency of the N2 and P3 potentials and the P3 amplitude recorded at Cz. At the time of audiological and electrophysiological evaluations, the average concentration of lead in the blood was less than 10 ug/dL. Results: In conventional audiologic evaluations, all children had hearing thresholds below 20 dBHL for the frequencies tested and normal tympanometry findings; the auditory evoked potential long latency N2 and cognitive P3 were present in 95% of children. No significant correlations were found between the blood lead concentration and latency (p = 0.821 or amplitude (p = 0.411 of the P3 potential. However, the latency of the N2 potential increased with the concentration of lead in the blood, with a significant correlation (p = 0.030. Conclusion: Among Brazilian children with low lead exposure, a significant correlation was found between blood lead levels and the average latency of the auditory evoked potential long latency N2; however, a significant correlation was not observed for the amplitude and latency of the cognitive potential P3.

  16. Take home lead exposure in children of oil field workers.

    Science.gov (United States)

    Khan, Fahad

    2011-06-01

    Childhood lead poisoning is a major, preventable environmental health problem. While residential lead-based paint and lead contaminated dust and soil are the most common sources of childhood lead poisoning, children can also be at risk if they live with an adult with a job or hobby that involves exposure to lead. Currently, the Oklahoma Childhood Lead Poisoning Prevention Program (OCLPPP) has a small number of cases of "take home" lead exposure in children of oil field workers. These workers may come in contact with a threading compound, "pipe dope" that can contain large amounts of lead. Workers handling this product may be exposed to lead by not following safety instructions. Additionally workers may not be provided the facilities to shower and change out of the contaminated clothing before leaving the work location. The OCLPPP recommends employers and worksites should consider effective alternative options like lead free biodegradable pipe dopes or dope free connections to prevent workers and their families from adverse health effects associated with lead.

    To construct informed conservation plans, researchers must go beyond understanding readily apparent threats such as habitat loss and bush-meat hunting. They must predict subtle and cascading effects of anthropogenic environmental modifications. This study considered a potential cascading effect of deforestation on the howler monkeys (Alouatta pigra) of Balancán, Mexico. Deforestation intensifies flooding. Thus, we predicted that increased flooding of the Usumacinta River, which creates large bodies of water that slowly evaporate, would produce increased lead content in the soils and plants, resulting in lead exposure in the howler monkeys. The average lead levels were 18.18 ± 6.76 ppm in the soils and 5.85 ± 4.37 ppm in the plants. However, the average lead content of the hair of 13 captured howler monkeys was 24.12 ± 5.84 ppm. The lead levels in the animals were correlated with 2 of 15 blood traits (lactate dehydrogenase and total bilirubin) previously documented to be associated with exposure to lead. Our research illustrates the urgent need to set reference values indicating when adverse impacts of high environmental lead levels occur, whether anthropogenic or natural, and the need to evaluate possible cascading effects of deforestation on primates.

  18. Lead neurotoxicity: exploring the potential impact of lead substitution in zinc-finger proteins on mental health.

    Ordemann, Jacqueline Michelle; Austin, Rachel Narehood

    2016-06-01

    Childhood lead poisoning is a costly and largely preventable public health problem that lowers IQs, decreases attention spans, and leads to the development of other childhood intellectual disabilities. Furthermore, recent evidence links developmental lead poisoning with the etiology of disorders that appear much later in life, such as Alzheimer's disease, Parkinson's disease, and schizophrenia. Little is known about how lead influences the onset of these disorders. This paper reviews the evidence that lead substitution for zinc in zinc-finger proteins contributes to the development of Alzheimer's disease, Parkinson's disease, and schizophrenia. The zinc-finger proteins potentially impacted by lead include DNA methyltransferase 1 (DNMT1) and Presenilin 1 and 2 (PSEN1/2) in Alzheimer's disease, the dopamine receptor in Parkinson's disease, and the NMDA receptor, zinc-finger protein 804A (ZNF804A), and disrupted-in-schizophrenia 1 (DISC1)-binding zinc-finger (DBZ) in schizophrenia.

    The in situ IR and Raman spectroscopy measurements were conducted to investigate lead poisoning on the CeO2-WO3 catalysts. The deactivation mechanisms were studied with respect to the changes of surface acidity, redox property, nitrate/nitrite adsorption behaviors, and key active sites (note that the results of structure-activity relationship of CeO2-WO3 were based on our previous research). (1) Lewis acid sites originated from CeO2 and crystalline WO3, whereas Brønsted acid sites originated from Ce2(WO4)3. The poisoned catalysts exhibited a lower surface acidity than the fresh catalysts: the number of acid sites decreased, and their thermal stability weakened. (2) The reducibility of catalysts and the amount of active oxygen exhibited a smaller influence after poisoning because lead preferred to bond with surface WOx species rather than CeO2. (3) The quantity of active nitrate species decreased due to the lead coverage on the catalyst and the partial bridged-nitrate species induced by lead exhibited a low degree of activity at 200 °C. (4) Crystalline WO3 and Ce2(WO4)3 originated from the transformation of polytungstate sites. These sites were the key active sites during the SCR process. The formation temperatures of polytungstate on the poisoned catalysts were higher than those on the fresh catalysts. PMID:27480109

We also found that mean Pb concentrations in secondary dentine (that is formed from root completion to tooth shedding correlated positively with cumulative blood lead index (Spearman ρ = 0.38; n = 75; p<0.0007. Overall, our results support that micro-spatial measurements of Pb in dentine can be reliably used to reconstruct Pb exposure timing over the prenatal and early childhood periods, and secondary dentine holds the potential to estimate long-term exposure up to the time the tooth is shed.

    The use of arsenic in ant poisons, herbicides, and insecticides affords the necessary contact with the poison by pets. The gastrointestinal tract appears to suffer the greatest though there may also be injury to the liver and kidneys. The treatments discussed were in relation to very early poisoning in which the owner had observed ingestion of the arsenic, and when the signs of the poisoning were evident. Early observation treatment included emptying the stomach before the arsenic passed in quantity into the intestine. If the signs of toxicity were already advanced, then the treatment consisted of the intramuscular administration of dimercaprol (BAL) at a dosage of 3 mg/lb of body weight three times a day until recovery. l reference.

    The use of arsenic in ant poisons, herbicides, and insecticides affords the necessary contact with the poison by pets. Treatment was discussed in relation to two circumstances: very early poisoning in which the owner has observed ingestion of the arsenic, and when the signs of the poisoning are evident. Treatment for early ingestion involves emptying the stomach before the arsenic can pass in quantity into the intestine. This is followed with a 1% solution of sodium bicarbonate, with the administering of 3 to 6 mg of apomorphine. When signs of arsenic toxicity are already advanced, there is little advantage to be gained by either gastric lavage or administration of an emetic. The treatment then consists of the intramuscular administration of dimercaprol (BAL) at a dosage of 3 mg/lb of body weight three times a day until recovery. This is the specific antidote for arsenic. 1 reference.

    Full Text Available Disastrous/hazardous environmental resource exploitation: mass lead-poisoning and mortality of chronically-poor artisanal gold miners’ children in northern Nigeria.The claim that poverty is one of three motivations of the nearly half a decade-long terrorist war waged by Northern Nigeria’s Islamic-sectarians, Boko Haram, call to question the extent to which sociological aspects of the critical social theory -emphasizing participation of various strata of the population in the rational society have been fulfilled in the sub-national region. The presentation of over 90 percent of Nigeria’s population (total: about 170 million classified as poor (earning/spending less than US$2 a day, vulnerable to socio-economic hazards, -with poverty in northern Nigeria reportedly surpassing levels in the rest of Nigeria’s federation makes questioning of geographers’ political-economic perspectives of critical social theoretical equally urgent. One of many dimensions of this challenge is its indication of Northern Nigeria’s leadership’s failure to seriously apply public resources towards resolving social welfare problems at both central and sub-national regional scales since the attainment of independence in 1960. The recent resort to insurgency represents mistakes of political gladiators during the post-independence era (over 50 years to properly manage natural resources –including solid minerals in northern Nigeria and the rest of the country. Here, we undertake a discourse of hazards (risks and vulnerabilities and disasters associated with recent resort of northern Nigeria’s poor to artisanal/unregulated mining of gold in northern Nigerian communities: cases of deleterious consequences (deaths, illnesses, etc., of this alternative “livelihood” of coping with socio-economic challenges posed by chronic poverty, unemployment, under-employment, among other adversities in the sub-national region were also highlighted.

    Arsenic poisoning continues to require awareness of its diverse clinical manifestations. Industry is the major source of arsenic exposure. Although epidemiologic studies strongly contend that arsenic is carcinogenic, there are little supportive research data. Arsenic poisoning, both acute and chronic, is often overlooked initially in the evaluation of the patient with multisystem disease, but once it is suspected, many accurate methods are available to quantitate the amount and duration of exposure. Treatment with dimercaprol remains the mainstay of therapy, and early treatment is necessary to prevent irreversible complications.

    2011-01-01

    Optimization of early diagnosis of childhood hypertrophic cardiomyopathy (HCM) is essential in lowering the risk of HCM complications. Standard echocardiography (ECHO) has shown to be less sensitive in this regard. In this study, we sought to assess whether spatial QRS-T angle deviation, which has shown to predict HCM in adults with high sensitivity, and myocardial Tissue Doppler Imaging (TDI) could be additional tools in early diagnosis of HCM in childhood. Methods: Children and adolescents with familial HCM (n=10, median age 16, range 5-27 years), and without obvious hypertrophy but with heredity for HCM (n=12, median age 16, range 4-25 years, HCM or sudden death with autopsy-verified HCM in greater than or equal to 1 first-degree relative, HCM-risk) were additionally investigated with TDI and advanced 12-lead ECG analysis using Cardiax(Registered trademark) (IMED Co Ltd, Budapest, Hungary and Houston). Spatial QRS-T angle (SA) was derived from Kors regression-related transformation. Healthy age-matched controls (n=21) were also studied. All participants underwent thorough clinical examination. Results: Spatial QRS-T angle (Figure/ Panel A) and septal E/Ea ratio (Figure/Panel B) were most increased in HCM group as compared to the HCM-risk and control groups (p less than 0.05). Of note, these 2 variables showed a trend toward higher levels in HCM-risk group than in control group (p=0.05 for E/Ea and 0.06 for QRS/T by ANOVA). In a logistic regression model, increased SA and septal E/Ea ratio appeared to significantly predict both the disease (Chi-square in HCM group: 9 and 5, respectively, p less than 0.05 for both) and the risk for HCM (Chi-square in HCM-risk group: 5 and 4 respectively, p less than 0.05 for both), with further increased predictability level when these 2 variables were combined (Chi-square 10 in HCM group, and 7 in HCM-risk group, p less than 0.01 for both). Conclusions: In this small material, Tissue Doppler Imaging and spatial mean QRS-T angle

    Full Text Available AML1 and ETO genes are known partners in the t(8,21 translocation associated with the treatment-related leukaemias in the patients receiving chemotherapy with DNA-topoisomerase II (topo II poisons. Aim. To determine whether the genes AML1 and ETO are in close proximity either permanently or temporarily in the nucleus. Methods. 3D FISH. Results. We found that in 5 % of untreated cells, alleles of AML1 and ETO are in close proximity. This number increased two-fold in the cells treated with the topo II poison etoposide. Surprisingly, in more than 50 % of the cases observed, co-localization of the genes occurred at the nucleoli surface. We found also that the treatment of cells triggers preferential loading of RAD51 onto bcr of the AML1 and ETO genes. Conclusions. Our results suggest that the repair of DNA lesions introduced by topoisomerase II poisons may be mediated simultaneously by multiple mechanisms, which may be the cause of mistakes resulting in translocations.

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

    Objective To explore the clinical diagnostic significance of variation of red blood cell parameters in children with chronic lead poisoning. Methods According to the clinical diagnoses, 375 children were divided into the normal group (n = 152), the high blood lead level group ( n = 131), and the chronic lead poisoning group (n = 92). And the blood cell parameters were compared among the three groups. Results There were significant differences in red blood cell counting (RBC), hemoglobin concentration (Hb), hematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) among the three groups. RBC, Hb, and Hct of the normal group weresignificantly higher than those of the high blood lead level group (P0. 05), but MCV, MCH, and MCHC of the chronic lead poisoning group were significantly lower than those of the normal group and the high blood lead level group (P< 0. 05). Conclusions The red blood cell parameters, including RBC, Hb, Hct, MCV, MCH, and MCHC decrease differently as a result of chronic lead poisoning. Determination of MCV, MCH, and MCHC is conducive to differential diagnosis of high blood lead level and chronic lead poisoning.%目的 探讨红细胞参数的变化对慢性铅中毒患儿的临床诊断意义. 方法 根据临床诊断将375例儿童分为3组,其中正常对照组152例,高铅血症组131例,慢性铅中毒组92例.对比分析上述3组儿童的红细胞参数. 结果 3组儿童红细胞计数(RBC)、血红蛋白浓度(Hb)、红细胞压积(Hct)、平均红细胞体积(MCV)、平均红细胞血红蛋白含量(MCH)、平均红细胞血红蛋白浓度(MCHC)的均数不全相等;正常对照组的RBC、Hb、Hct显著高于高铅血症组(P<0.05),高铅血症组的RBC、Hb、Hct显著高于慢性铅中毒组(P<0.05);正常对照组与高铅血症组的MCV、MCH、MCHC相比差异无统计学意义(P>0.05),慢性铅中毒组

    Objective:To evaluate the feasibility of a .portable X - Ray Fluorescence Analyzer (XRF) in searching the cause of pediatric lead poisoning. Methods:In a family with two children confirmed as lead poisoning, all articles that the children could reach or may be affected (including wall, furniture, foodstuff, dishware, water and toys) were detected for lead contents with a XRF to find out the latent exposure. Results:Among the sampled articles, sofa, paint of the balcony bars and baby powder had higher lead concentrations with 1741 mg/kg, 8700 mg/kg and more than 100000 mg/kg, respectively. But the two children had not yet bitten or licked the sofa and the bar painting was not peeling. But the children had been being rubbed baby powder by their parent since birth. Farther investigation revealed the lead in the powder came from red lead which was mixed intentionally. The blood lead levels of two children decreased rapidly after disuse of this baby powder. Conclusion:The portable XRF is an effective tool for searching the exposure source of pediatric lead poisoning in scene and can find out real cause for poisoning when integrated with questionnaire.%目的:掌握便携式X线荧光分析仪(XRF)用于铅中毒溯源调查的可行性.方法:在1家庭2幼儿铅中毒调查个案中,用XRF对其家庭内环境、食品、餐具、饮用水和儿童用品进行检测,寻找可疑铅暴露.结果:在抽查的27种物品中,铅含量较高的是皮沙发表面(1741 mg/kg)、阳台护栏油漆(8700 mg/kg)和散装无牌爽身粉(>100000 mg/kg),但两幼儿没有啃咬皮沙发的习惯,护栏油漆也没有破损脱落,两幼儿都有经常使用这种无牌散装爽身粉的习惯,经进一步调查爽身粉中的铅来自于配制中人为加入的红丹.病人脱离接触红丹爽身粉后血铅水平下降.结论:XRF是现场调查儿童铅中毒来源行之有效方法,结合问卷可快速找出暴露的原因.

    Full Text Available Exposure to toxic metals remains a wide spread occupational and environmental problems in world. Due to their widespread use in human activities such as industry, agriculture and even as medicine numerous health risks may be associated with exposure to these substances. Lead, arsenic and cadmium generally interferes with a number of body functions such as the haematopoietic system, central nervous system (CNS, liver and kidneys. Over the past few decades there have been growing awareness and concern that the toxic biochemical and functional effects are occurring at lower level of metal exposure than those that produce overt clinical and pathological signs and symptoms. Despite many years of research we are still far from an effective treatment of chronic heavy metal poisoning. The main therapeutic option for chronic metal poisoning relies in chelation therapy. Chelating agents are capable of linking together metal ions to form complex structures which can be easily excreted from the body. They have been used clinically as antidotes for acute and chronic poisoning. 2, 3-dimercaprol (BAL has long been the mainstay of chelation therapy of lead or arsenic poisoning. Meso 2, 3, -dimercaptosuccinic acid (DMSA has been tried successfully in animals as well as in few cases of human lead or arsenic poisoning. However, one of the major disadvantages of chelation with DMSA has been its inability to remove heavy metal from the intracellular sites because of its lipophobic nature. Further, it does not provide protection in terms of clinical/ biochemical recovery. A new trend in chelation therapy has emerged to use combined treatment. This includes use of structurally different chelating agents or a combination of an antioxidant and a chelator to provide better clinical/biochemical recovery in addition to mobilization of heavy metal form intracellular sites. The present review article attempts to provide update information about the current strategies being

    BACKGROUND: There ha s been no consensus regarding whether lead poisoning can cause osteoporosis and whether estradiol exhibits curative effects on osteoporosis.OBJECTIVE: To observe the curative effects of estradiol on osteoporosisinduced by ovariectomy and lead poisoning in rats.METHODS: A total of 100 female rats were randomly and evenly divided into five g roups: normal control, ovariectomized, lead poisoning, estradiol+ovariectomized and estradiol+lead poisoning. At 1 week after ovariectomy, estradiol (100 μg/kg) was subcutaneously injected into the rats in the estradiol+ovariectomized and estradiol+lead poisoning groups, twice a week, for successive 12 weeks.RESULTS AND CONCLUSION: In the ovariectomized group and lead poisoning group, calcium and phosphoruslevelsin the bone and serum were significantly decreased (P < 0.01), serum level of alkaline phosphatase was significantly increased (P<0.01), and bone tissue showed the pathological change of osteoporosis. In the estradiol+ovariectomized group, serum levels of calcium, phosphorus, and alkaline phosphatase and bone tissue morphology returned to normal, while in the estradiol+lead poisoning group, no obvious changes in bone metabolism indices and bone tissue morphology above-mentioned did not recover obviously. The lead level in the bone and serum was significantly higher in the lead poisoning group, estradiol+lead poisoning group than in the normal control group (P < 0.01). These results showed that lead poisoning can cause osteoporosis, and estradiol exhibits good curative effects on osteoporosiscaused by ovariectomy in rats, but it does not produce obvious curative effects on osteoporosiscaused by lead poisoning.%背景:关于铅中毒能否引起骨质疏松症及雌激素对其治疗是否有效尚无共识.目的:观察雌二醇对去卵巢大鼠和铅中毒大鼠所致骨质疏松症的治疗效果.方法:雌性大白鼠100 只等分成正常对照组、去卵巢模型组、染铅模型组、

    Objective; To study the relationship between intelligent change and brain evoked potential among the children with lead poisoning, explore the electrophysiological basis of neurotoxicity and psychological and behavioral changes among the children with lead poisoning. Methods: According to the blood lead levels, social and family investigation with a questionnaire, after excluding several important effect factors of intelligence, forty-five children aged 6-12 years meeting the criterion were divided into high lead group (blood lead level ≥10μg/dl) and normal group (blood lead level < 10 μg/dl) . The children were detected by WISC, sensory evoked potential (SEP) detection, and event - related potentials (ERP) detection, respectively. The degrees of injuries of lead poisoning to intelligence, sensory system, and advance mental function were entirely evaluated. Results; The full scale intelligence quotient and verbal intelligence quotient of high lead group were significantly lower than those of normal group. The performance intelligence quotient decreased, but there was no significant difference between the two groups. There was no significant difference in P15, N20, P25 of early cortical potential of SEP between the two groups, but there was significant difference in late cortical potential, the elongation of N35, P45, and N60 was the main manifestation. Among P300 waves, there was no significant difference in N100 and P200 between the two groups, but the amplitudes of P300 and N200 decreased significantly , and the latent period extended obviously. Conclusion: The study provides an objective and electrophysiological basis for neurotoxicity and abnormality of cognitive and psychological behaviors of children with lead poisoning, observing prevention, which also provides electrophysiological basis for diagnosis, and treatment of lead poisoning among children.%目的:研究儿童铅中毒的智力改变与脑诱发电位的关系,探索儿童铅中毒的神经毒

    Arsenic (As) is commonly known as a poison. Only a few people know that As has also been widely used in medicine. In the past years As and its compounds were used as a medicine for the treatment of such diseases as diabetes, psoriasis, syphilis, skin ulcers and joint diseases. Nowadays As is also used especially in the treatment of patients with acute promyelocytic leukemia. The International Agency for Research on Cancer (IARC) has recognized arsenic as an element with carcinogenic effect evidenced by epidemiological studies, but as previously mentioned it is also used in the treatment of neoplastic diseases. This underlines the specificity of the arsenic effects. Arsenic occurs widely in the natural environment, for example, it is present in soil and water, which contributes to its migration to food products. Long exposure to this element may lead to liver damages and also to changes in myocardium. Bearing in mind that such serious health problems can occur, monitoring of the As presence in the environmental media plays a very important role. In addition, the occupational risk of As exposure in the workplace should be identified and checked. Also the standards for As presence in food should be established. This paper presents a review of the 2015 publications based on the Medical database like PubMed and Polish Medical Bibliography. It includes the most important information about arsenic in both forms, poison and medicine.

    Lead (Pb) levels, delta-aminolevulinic acid dehydratase (ALAD) activities, zinc protoporphyrin (ZPP) levels in blood, and urinary delta-aminolevulinic acid (ALA) and coproporphyrin (CP) concentrations were measured for 318 environmental Pb exposed children recruited from an area of southeast China. The mean of blood lead (PbB) levels was 75.0μg/L among all subjects. Benchmark dose (BMD) method was conducted to present a lower PbB BMD (lower bound of BMD) of 32.4μg/L (22.7) based on ALAD activity than those based on the other three haematological indices, corresponding to a benchmark response of 1%. Childhood intelligence degrees were not associated significantly with ALAD activities or ALA levels. It was concluded that blood ALAD activity is a sensitive indicator of early haematological damage due to low-level Pb exposures for children.

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

    Misdiagnosis of diseases as due to industrial poisoning leads to much misunderstanding, higher taxes and insurance rates and "compensation neuroses." It is important to know the concentration of the suspected poison and its specific effects in order to logically indict it as the cause of illness. Examples discussed to illustrate some of the pitfalls of diagnosis in industrial medicine are methylbromide, carbon monoxide, ozone, oxides of nitrogen and of sulfur, hydrogen sulfide, benzene analogs, boron and fluorides.

    A preliminary survey of a remote mining and smelting region of the Russian Far East (RFE) indicates significant soil lead contamination and a high probability of childhood lead poisoning. Lead concentrations in residential gardens (476-4310 mg/kg, Gmean=1626 mg/kg) and in roadside soils (2020-22900 mg/kg, Gmean=4420 mg/kg) exceed USEPA guidance for remediation. Preliminary biokinetic estimates of mean blood levels suggest that preschool children are at significant risk of lead poisoning from soil/dust ingestion with levels predicted to average 13-27 microg/dl. Samples of other pathways, such as air, water, paint, interior dust, and garden produce, and pediatric and occupational blood lead levels are needed. An assessment of the industry's ability to improve emissions controls and materials handling should also be undertaken. Global lessons in remediating contamination problems and preventing childhood lead poisoning must be applied in innovative ways to meet the logistical, social, and economic challenges in the RFE.

    The fast ripening of fruits means they may contain various harmful properties. A commonly used agent in the ripening process is calcium carbide, a material most commonly used for welding purposes. Calcium carbide treatment of food is extremely hazardous because it contains traces of arsenic and phosphorous. Once dissolved in water, the carbide produces acetylene gas. Acetylene gas may affect the neurological system by inducing prolonged hypoxia. The findings are headache, dizziness, mood disturbances, sleepiness, mental confusion, memory loss, cerebral edema and seizures. We report the case of a previously healthy 5 year-old girl with no chronic disease history who was transferred to our Emergency Department with an 8-h history of coma and delirium. A careful history from her father revealed that the patient ate unripe dates treated with calcium carbide.

    Studies have shown that the environmental conditions of the home are important predictors of health, especially in low-income communities. Understanding the relationship between the environment and health is crucial in the management of certain diseases. One health outcome related to the home environment among urban, minority, and low-income children is childhood lead poisoning. The most common sources of lead exposure for children are lead paint in older, dilapidated housing and contaminated dust and soil produced by accumulated residue of leaded gasoline. Blood lead levels (BLL) as low as 10 microg/dL in children are associated with impaired cognitive function, behavior difficulties, and reduced intelligence. Recently, it is suggested that the standard for intervention be lowered to BLL of 5 microg/dl. The objectives of our report were to assess the prevalence of lead poisoning among children under six years of age and to quantify and test the correlations between BLL in children and lead exposure levels in their environment. This cross-sectional analysis was restricted to 75 children under six years of age who lived in 6 zip code areas of inner city Miami. These locations exhibited unacceptably high levels of lead dust and soil in areas where children live and play. Using the 5 microg/dL as the cutoff point, the prevalence of lead poisoning among the study sample was 13.33%. The study revealed that lead levels in floor dust and window sill samples were positively and significantly correlated with BLL among children (p air, and water samples were not significant. Based on this pilot study, a more comprehensive environmental study in surrounding inner city areas is warranted. Parental education on proper housecleaning techniques may also benefit those living in the high lead-exposed communities of inner city Miami.

    In Thailand, each year approximately 15,000 people die from accidents, a figure exceeded only by cardiovascular diseases. Motor vehicle accidents (MVA) is the principal cause of death and injuries in children of all ages except preschool group. In 1988 there were 554,452 cases of injuries out of which 10,031 died from MVA. In Bangkok alone MVA accounts for an average of 300 childhood and teenage death and 1,900 cases of injuries each year. Falls, burns and poisonings are relatively high in children less than 4 years old while MVA and injuries from sharp and blunt objects of both accidental and non-accidental cases increase with age and become the two leading causes of injury in older children. The sex ratio (F:M) in preschool ages are 1:1.4 and 1:2 in preteen. Poisonings, though less common, are considered to be very important because of their severity. Drugs, hydrocarbon, insecticides, lead and corrosive substances are leading agents. As for injuries caused by animals, 150 cases of rabies were reported each year while around 5,000 cases of snake bites were found in 1987 and 20 per cent of the victims were children. The study from Ramathibodi Hospital revealed that the majority of accidents (65-72%) occur at home and 20 per cent in the street in children younger than 12 years. Peak incidence were found between 5-9 pm. During weekend and holidays the incidence is higher. Ninety-five per cent of the accidents reported were mild cases, 15 per cent moderate, 3 per cent severe and less than 1 per cent caused death. PMID:7822995

    Full Text Available Plants are responsible for 5% poisoning recorded by Poison Control Centers. Among all known toxic plants, some present a real danger if ingested. We report the case of a five years old child, who presented, after ten bitter almonds ingestion, consciousness disorders progressing to coma with generalized tonic-clonic seizures, miosis and metabolic acidosis. Bitter almonds and nuclei of stone fruits or other rosaceae (apricot, peach, plum contain cyanogenic glycosides, amygdalin, that yields hydrogen cyanide when metabolized in the body. Swallowing six to ten bitter almonds may cause serious poisoning, while the ingestion of fifty could kill a man. The binding of cyanide ions on cytochrome oxidase lead to a non hypoxemic hypoxia by blocking the cellular respiratory chain. Therapeutic measures include, oxygen support, correction of acidosis and cyanide antidote by hydroxocobalamin in case of serious poisoning.

    International Nuclear Information System (INIS)

    The coordination chemistry and solution behavior of the toxic ions lead(II) and plutonium(IV, V, VI) have been investigated. The ligand pKas and ligand-lead(II) stability constants of one hydroxamic acid and four thiohydroaxamic acids were determined. Solution thermodynamic results indicate that thiohydroxamic acids are more acidic and slightly better lead chelators than hydroxamates, e.g., N-methylthioaceto-hydroxamic acid, pKa = 5.94, logβ120 = 10.92; acetohydroxamic acid, pKa = 9.34, logβl20 = 9.52. The syntheses of lead complexes of two bulky hydroxamate ligands are presented. The X-ray crystal structures show the lead hydroxamates are di-bridged dimers with irregular five-coordinate geometry about the metal atom and a stereochemically active lone pair of electrons. Molecular orbital calculations of a lead hydroxamate and a highly symmetric pseudo octahedral lead complex were performed. The thermodynamic stability of plutonium(IV) complexes of the siderophore, desferrioxamine B (DFO), and two octadentate derivatives of DFO were investigated using competition spectrophotometric titrations. The stability constant measured for the plutonium(IV) complex of DFO-methylterephthalamide is logβ110 = 41.7. The solubility limited speciation of 242Pu as a function of time in near neutral carbonate solution was measured. Individual solutions of plutonium in a single oxidation state were added to individual solutions at pH = 6.0, T = 30.0, 1.93 mM dissolved carbonate, and sampled over intervals up to 150 days. Plutonium solubility was measured, and speciation was investigated using laser photoacoustic spectroscopy and chemical methods

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

    1989-10-27

    A 67-year-old woman with portal hypertension, splenomegaly without portal vein thrombosis, leucopenia and thrombocytopenia of splenic origin had repeated episodes of life-threatening haemorrhage from esophageal varices. Since childhood she had suffered from psoriasis and had been treated over a period of 15 years with Fowler's solution (in all about 25 g of arsenic trioxide). She had the characteristic skin lesions of arsenical poisoning-palmar hyperkeratoses and two basal cell carcinomas on the trunk. Histological examination of a wedge biopsy from the liver showed definite structural changes with fibrosis around the central veins and in the portal tracts. There was no evidence of cirrhotic alteration. The hepatocytes were normal by light microscopy and electron microscopy. This case of noncirrhotic hepatic fibrosis is considered to have been caused by chronic arsenical poisoning.

  16. What do we know of childhood exposures to metals (arsenic, cadmium, lead, and mercury) in emerging market countries?

    2013-01-01

    Arsenic, cadmium, lead, and mercury present potential health risks to children who are exposed through inhalation or ingestion. Emerging Market countries experience rapid industrial development that may coincide with the increased release of these metals into the environment. A literature review was conducted for English language articles from the 21st century on pediatric exposures to arsenic, cadmium, lead, and mercury in the International Monetary Fund's (IMF) top 10 Emerging Market countries: Brazil, China, India, Indonesia, Mexico, Poland, Russia, South Korea, Taiwan, and Turkey. Seventy-six peer-reviewed, published studies on pediatric exposure to metals met the inclusion criteria. The reported concentrations of metals in blood and urine from these studies were generally higher than US reference values, and many studies identified adverse health effects associated with metals exposure. Evidence of exposure to metals in the pediatric population of these Emerging Market countries demonstrates a need for interventions to reduce exposure and efforts to establish country-specific reference values through surveillance or biomonitoring. The findings from review of these 10 countries also suggest the need for country-specific public health policies and clinician education in Emerging Markets.

  17. Licenced to pollute but not to poison: The ineffectiveness of regulatory authorities at protecting public health from atmospheric arsenic, lead and other contaminants resulting from mining and smelting operations

    2014-09-01

    This article details and examines the impact of significant inconsistencies in pollution licencing, monitoring and reporting from Australia’s leading mining and smelting communities of Mount Isa in Queensland and Port Pirie in South Australia. Although emissions to the environment are regulated according to Australia’s national air quality standards, significant atmospheric point source toxic emissions of arsenic, lead and sulfur dioxide continue to contaminate Mount Isa and Port Pirie communities. Short-term atmospheric contaminant emissions across residential areas from the Mount Isa Mines operations are significant: in 2011, 24-h maximum suspended particulate (TSP) values for lead-in-air and arsenic-in-air were 12.8 μg/m3 and 2973 ng/m3, respectively. The relevant Queensland air quality objectives for lead and arsenic are 0.5 μg/m3 (TSP) and 6 ng/m3 (PM10), respectively, averaged over a year. Mount Isa is also blanketed by elevated sulfur dioxide concentrations, with the Australian and Queensland 1-h air quality standard (0.2 ppm) being exceeded on 27 occasions in 2011. At Port Pirie, contamination of the urban environment is arguably worse with 24-h maximum TSP values for lead-in-air and arsenic-in-air of 22.57 μg/m3 (2011) and 250 ng/m3 (2009), respectively. Port Pirie has an annual average lead-in-air standard of 0.5 μg/m3 (TSP) but there are no set values for arsenic. In 2012, the national 1-h standard for sulfur dioxide was exceeded 50 times in Port Pirie. Despite chronic childhood blood lead exposures in both communities, there is a history of denial and downplaying of the source and impact of the contamination. A contributory factor to this pattern of behaviour is the fragmented and inconsistent delivery of data as well as its interpretation in relation to environmental and health impacts from exposures. This study reviews available data sources and makes inference to the impacts from contamination and in doing so, explains why the current

    2005-01-01

    Full Text Available Acute organic insecticide poisoning is a major health problem all over the world, particularly in the developing countries, where organophosphates (OPs are the most common suicidal poisons with high morbidity and mortality and account for a large proportion of patients admitted to intensive care units. Other insecticides less commonly used are organocarbamates, organochlorides, and pyrethroids, which are less toxic and are associated with less morbidity and mortality. Patients with poisoning present with a wide spectrum of gastrointestinal, neurological, and cardiac manifestations. A strong clinical suspicion is necessary to make an early diagnosis and to start appropriate therapy. Treatment is primarily supportive and includes decontamination, anticholinergics, protection of the airway, and cardiac and respiratory support. The use of oximes has been controversial and may be associated with higher mortality owing to a higher incidence of type-II paralysis. They may have other toxic side effects. This paper reviews the literature on OP poisoning.

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

    Heavy metal poisoning can cause a variety of hematologic disorders. Exposure to heavy metals is ubiquitous in the industrial environment and must be considered in the differential diagnosis of many types of anemia. The heavy metals most commonly associated with hematologic toxicity are arsenic and its derivative arsine, copper, gold, lead, and zinc. A few distinctive clinical features characterize the hematologic manifestations of many occult heavy metal poisonings. These features have a limited differential diagnosis. A knowledge of these clinical features can assist the astute clinician in making the correct diagnosis.

  16. Pancreatitis in wild zinc-poisoned waterfowl

    Sileo, Louis; Beyer, W. Nelson; Mateo, Rafael

    2003-01-01

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

    2005-07-16

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

  9. Arsenic – Poison or medicine?

    Directory of Open Access Journals (Sweden)

    Karolina Kulik-Kupka

    2016-04-01

    Full Text Available Arsenic (As is commonly known as a poison. Only a few people know that As has also been widely used in medicine. In the past years As and its compounds were used as a medicine for the treatment of such diseases as diabetes, psoriasis, syphilis, skin ulcers and joint diseases. Nowadays As is also used especially in the treatment of patients with acute promyelocytic leukemia. The International Agency for Research on Cancer (IARC has recognized arsenic as an element with carcinogenic effect evidenced by epidemiological studies, but as previously mentioned it is also used in the treatment of neoplastic diseases. This underlines the specificity of the arsenic effects. Arsenic occurs widely in the natural environment, for example, it is present in soil and water, which contributes to its migration to food products. Long exposure to this element may lead to liver damages and also to changes in myocardium. Bearing in mind that such serious health problems can occur, monitoring of the As presence in the environmental media plays a very important role. In addition, the occupational risk of As exposure in the workplace should be identified and checked. Also the standards for As presence in food should be established. This paper presents a review of the 2015 publications based on the Medical database like PubMed and Polish Medical Bibliography. It includes the most important information about arsenic in both forms, poison and medicine. Med Pr 2016;67(1:89–96

    Full Text Available Chelation therapy has been the major treatment for heavy metal poisoning. Various chelating agents have been developed and tested for treatment of heavy metal intoxications, including mercury poisoning. It has been clearly shown that chelating agents could rescue the toxicity caused by heavy metal intoxication, but the potential preventive role of chelating agents against heavy metal poisoning has not been explored much. Recent paper by Siddiqi and colleagues has suggested a protective role of chelating agents against mercury poisoning, which provides a promising research direction for broader application of chelation therapy in prevention and treatment of mercury poisoning.

  13. Heterogeneous burnable poisons:

    International Nuclear Information System (INIS)

    The use of materials possessing high neutron absorption cross-section commonly known as 'burnable poisons' have its origin in BWR reactors with the purpose of improving the efficiency of the first fuel load. Later on, it was extended to PWR to compensate of initial reactivity without infringing the requirement of maintaining a negative moderator coefficient. The present tendency is to increase the use of solid burnable poisons to extend the fuel cycle life and discharge burnup. There are two concepts for the burnable poisons utilization: 1) heterogeneously distributions in the form of rods, plates, etc. and 2) homogeneous dispersions of burnable poisons in the fuel. The purpose of this work is to present the results of sinterability studies, performed on Al2O3-B4C and Al2O3-Gd2O3 systems. Experiments were carried on pressing at room temperature mixtures of powders containing up to 5 wt % of B4C or Gd2O3 in Al2O3 and subsequently sintering at 1750 deg C in reducing atmosphere. Evaluation of density, porosity and microstructures were done and a comparison with previous experiences is shown. (Author)

  15. Towards the prevention of lead exposure in South Africa: contemporary and emerging challenges.

    Science.gov (United States)

    Mathee, Angela

    2014-12-01

    The prevention of lead exposure continues to constitute a major public health challenge in developed countries. In well-resourced countries major lead exposure reduction interventions have resulted in significant improvements in childhood blood lead distributions. In developing countries on the other hand, while lead exposure and poisoning remain serious public health concerns, a range of prevailing factors and circumstances, such as poverty, a large informal sector, competing public health challenges, low levels of awareness of lead hazards and weak capacity to enforce legislation, contribute to an increase in the scale and intensity of the challenge, and limit the prospects of comparable success in the foreseeable future. This paper collates available information to illustrate that despite some progress, a wide range of sources of lead exist in South Africa, and that certain settings and groups continue to be at high risk of lead exposure. Lead exposure in relation to paint, mining, lead melting in subsistence fishing communities, the consumption of Ayurvedic medicines and food production is described, and discussed with regard to the key factors hindering efforts to prevent lead poisoning and exposure in South Africa and many other developing countries.

    Perković-Vukčević Nataša

    2016-01-01

    Full Text Available Background/Aim. Benzodiazepines are among the most frequently ingested drugs in self-poisonings. Elderly may be at greater risk compared with younger individuals due to impaired metabolism and increased sensitivity to benzodiazepines. The aim of this study was to assess toxicity of benzodiazepines in elderly attempted suicide. Methods. A retrospective study of consecutive presentations to hospital after self-poisoning with benzodiazepines was done. Collected data consisted of patient's characteristics (age, gender, benzodiazepine ingested with its blood concentrations at admission, clinical findings including vital signs and Glasgow coma score, routine blood chemistry, complications of poisoning, details of management, length of hospital stay and outcome. According the age, patients are classified as young (15-40-year old, middle aged (41-65-year old and elderly (older than 65. Results. During a 2-year observational period 387 patients were admitted because of pure benzodiazepine poisoning. The most frequently ingested drug was bromazepam, the second was diazepam. The incidence of coma was significantly higher, and the length of hospital stay significantly longer in elderly. Respiratory failure and aspiration pneumonia occurred more frequently in old age. Also, flumazenil was more frequently required in the group of elderly patients. Conclusion. Massive benzodiazepines overdose in elderly may be associated with a significant morbidity, including deep coma with aspiration pneumonia, respiratory failure, and even death. Flumazenil is indicated more often to reduce CNS depression and prevent complications of prolonged unconsciousness, but supportive treatment and proper airway management of comatose patients is the mainstay of the treatment of acute benzodiazepine poisoning.

    Markowitz, G; Rosner, D

    2000-01-01

    A major source of childhood lead poisoning, still a serious problem in the United States, is paint. The dangers of lead were known even in the 19th century, and the particular dangers to children were documented in the English-language literature as early as 1904. During the first decades of the 20th century, many other countries banned or restricted the use of lead paint for interior painting. Despite this knowledge, the lead industry in the United States did nothing to discourage the use of lead paint on interior walls and woodwork. In fact, beginning in the 1920s, the Lead Industries Association and its members conducted an intensive campaign to promote the use of paint containing white lead, even targeting children in their advertising. It was not until the 1950s that the industry, under increasing pressure, adopted a voluntary standard limiting the amount of lead in interior paints.

    Full Text Available Background & aim: About 7% of patient referred to hospital are various forms of poisoning. This study was performed to determine the major causes of acute poisoning leading to Hospitalization at Shahid Beheshti Hospital of Yasuj, Iran. Methods: This descriptive study was performed from August 2007 to July 2008 on 470 cases of poisonings referred to Shahid Beheshti hospital of Yasuj. Demographic characteristics, time of poisoning, poisoning factor, history of previous poisoning, history of psychiatric disease, medication and other therapeutic intervention based on questionnaires and interviews with patients or companions of patients were recorded. Data were analyzed by Chi-Square Test. Results: Majority of poisoned patients were single females, in the age range of 21-30 years, unemployed, lived in urban areas, and had at least a diploma. The majority of cases were intentional poisoning with a history of depression, previous poisoning and attempted suicide. Significant relationship were seen between poisoning, age, sex, and job, (p0.05. Conclusion: With respect to the results of this study, the majority of these poisonings occurred among young, single and unemployed females due to suicide and drug intoxication. Necessary actions should be done in drug usage and maintenance, taking action against non-prescription drugs and giving proper public education to families.

    2012-01-01

    We present practical poisoning and name-server block- ing attacks on standard DNS resolvers, by off-path, spoofing adversaries. Our attacks exploit large DNS responses that cause IP fragmentation; such long re- sponses are increasingly common, mainly due to the use of DNSSEC. In common scenarios, where DNSSEC is partially or incorrectly deployed, our poisoning attacks allow 'com- plete' domain hijacking. When DNSSEC is fully de- ployed, attacker can force use of fake name server; we show exploits of this allowing off-path traffic analy- sis and covert channel. When using NSEC3 opt-out, attacker can also create fake subdomains, circumvent- ing same origin restrictions. Our attacks circumvent resolver-side defenses, e.g., port randomisation, IP ran- domisation and query randomisation. The (new) name server (NS) blocking attacks force re- solver to use specific name server. This attack allows Degradation of Service, traffic-analysis and covert chan- nel, and also facilitates DNS poisoning. We validated the attac...

    Hall, Alan H

    2002-03-10

    Symptomatic arsenic poisoning is not often seen in occupational exposure settings. Attempted homicide and deliberate long-term poisoning have resulted in chronic toxicity. Skin pigmentation changes, palmar and plantar hyperkeratoses, gastrointestinal symptoms, anemia, and liver disease are common. Noncirrhotic portal hypertension with bleeding esophageal varices, splenomegaly, and hypersplenism may occur. A metallic taste, gastrointestinal disturbances, and Mee's lines may be seen. Bone marrow depression is common. 'Blackfoot disease' has been associated with arsenic-contaminated drinking water in Taiwan; Raynaud's phenomenon and acrocyanosis also may occur. Large numbers of persons in areas of India, Pakistan, and several other countries have been chronically poisoned from naturally occurring arsenic in ground water. Toxic delirium and encephalopathy can be present. CCA-treated wood (chromated copper arsenate) is not a health risk unless burned in fireplaces or woodstoves. Peripheral neuropathy may also occur. Workplace exposure or chronic ingestion of arsenic-contaminated water or arsenical medications is associated with development of skin, lung, and other cancers. Treatment may incklude the use of chelating agents such as dimercaprol (BAL), dimercaptosuccinic acid (DMSA), and dimercaptopanesulfonic acid (DMPS).

Heavy metals are natural components of the Earth's crust. They cannot be degraded or destroyed. To a small extent they enter animal organism via food, drinking water and air. Some heavy metals (e.g cooper, iron, chromium, zinc are essential in very low concentrations for the survival of all forms of life. These are described as essential trace elements. However, when they are present in greater quantities, like the heavy metals lead, cadmium and mercury which are already toxic in very low concentrations, they can cause metabolic anomalies or poisoning. Heavy metal poisoning of domestic animals could result, for instance, from drinking-water contamination, high ambient air concentrations near emission sources, or intake via the food chain. Heavy metals are dangerous because they tend to bioaccumulate in a biological organism over time. Manifestation of toxicity of individual heavy metals varies considerably, depending on dose and time of exposure, species, gender and environmental and nutritional factors. Large differences exist between the effects of a single exposure to a high concentration, and chronic exposures to lower doses. The aim of this work is to present the source of poisoning and toxicity of some heavy metals (lead, mercury, cadmium, thallium, arsenic, as well as new data about effects of those heavy metals on the health of domestic animals. .

  17. The power of poison: pesticide poisoning of Africa's wildlife.

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

    Full Text Available Acute organophosphate (OP poisoning is one of the most common poisonings in emergency medicine and toxicological practice in some of the less-developed nations in South Asia. Traditionally, OP poisoning comes under the domain of emergency physicians, internists, intensivists, and toxicologists. However, some of the complications following OP poisoning are neurological and involve neurologists. The pathophysiological basis for the clinical manifestations of OP poisoning is inactivation of the enzyme, acetylcholinesterase at the peripheral nicotinic and muscarinic and central nervous system (CNS nerve terminals and junctions. Nicotinic manifestations occur in severe cases and late in the course; these comprise of fasciculations and neuromuscular paralysis. There is a good correlation between the electrophysiological abnormalities and the severity of the clinical manifestations. Neurophysiological abnormalities characteristic of nicotinic junctions (mainly neuromuscular junction dysfunction include: (1 single, supramaximal electrical-stimulus-induced repetitive response/s, (2 decrement-increment response to high frequency (30 Hz repetitive nerve stimulation (RNS, and (3 decremental response to high frequency (30 Hz RNS. Atropine ameliorates muscarinic manifestations. Therapeutic agents that can ameliorate nicotinic manifestations, mainly neuromuscular, are oximes. However, the evidence for this effect is inconclusive. This may be due to the fact that there are several factors that determine the therapeutic effect of oximes. These factors include: The OP compound responsible for poisoning, duration of poisoning, severity of poisoning, and route of exposure. There is also a need to study the effect of oximes on the neurophysiological abnormalities.

    The incidence of fatal poisoning of birds of prey caused by carbofuran has increased markedly in Hungary since 2007. An experimental model with broiler chickens was used to study clinical signs of sublethal carbofuran poisoning in birds and to measure the residue concentrations of carbamate in tissues after exposure. Eight chickens were treated with a carbofuran-containing insecticide orally by gastric tube at a single dose of 2.5 mg/kg body weight, and clinical signs of poisoning were observed. Gas chromatography was used to determine carbofuran concentrations in the blood, muscle, and liver samples, and in stomach contents. Poisoning was characterized by typical muscarinic and nicotinic clinical signs without mortality. Carbofuran in the stomach and edible tissues of acutely poisoned birds may lead to secondary poisoning of predators and may also present risks to human health.

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

    Full Text Available Poisoning is an emerging problem worldwide. According to WHO, 3 million acute poisoning cases with 2,20,000 deaths occur annually. Of these, 90% of fatal poisoning occurs in developing countries mainly among agricultural workers. It is estimated that more than 50,000 people die every year from toxic exposure in India. OBJECTIVES 1. To study the current trend of poisoning in a District of West Bengal. 2. To know the burden of pesticide poisoning in society. MATERIAL AND METHODS A hospital based retrospective cross sectional study was conducted in a district hospital of West Bengal. Ethical clearance was taken from Ethics Committee. All the registered cases of poisoning in a district hospital during the study period were included in the study. Data was collected from medico-legal register and respective case sheets using pre-structured and validated questionnaire containing demographic and medico-legal aspects of poisoning for the period of 2 years (March 2014-March 2016. Data was analysed using the SPSS version 16 software. Descriptive statistics were reported as mean (SD for continuous variables and frequency (percentage for categorical variables. RESULT Total 7280 patients reported to casualty department over two years; 5.21% were reported to be the poisoning cases. Out of total 380 poisoning cases, 84 (22.10% patients died. Maximum poisoning cases were from rural area falling mainly in the age group of 21-30 and above 50 years. Organ phosphorus poisoning was noted in 46.42% of reported cases. CONCLUSIONS Based on the study findings, we could understand the trend of poisoning in the study area. It is very important to identify these changing trends in the study area, as it will be helpful for policy makers to equip health care institutions which can lead to better management of cases and reduction in the mortality related to poisoning

    Full Text Available Context: India is a developing country in south Asia. Rural population of this country is mostly dependant on agriculture. Pesticides, mainly the organophosphorus compounds are the most frequently used substances in agriculture and thus are easily accessible. Animal bites such as snake bite, scorpion bites are also common, as people here are mainly involved in the field work. Aims: This includes, knowing the pattern of poisoning in India along with various parameters, such as mode of poisoning, type of poison, outcome of the poisoning, the most vulnerable age group involved in poisoning, so that the study will help in rapid clinical diagnosis and immediate treatment of the cases leading to decreased mortality and morbidity. Setting and design: Retrospective observational study. Materials and Methods: The study was conducted at Govt. Hospital, Yavatmal. Poisoning cases reported to casualty and post-mortem cases of poisoning brought to the hospital from 01/06/2003 to 30/05/2004 were included in the study. Result: Total 1003 patients studied; acute poisoning in the age group of 21-30 years was the most common with higher frequency in males. Most common mode was suicidal. Most common agent responsible for poisoning was organophosphorus compounds followed by snake bite. Overall mortality due to poisoning was 12%. It was highest in insecticidal poisoning. Conclusion: It was seen that adults between 21 and 30 years of age were more prone to suicidal poisoning with organophosphorous compounds followed by accidental poisoning due to snake bite. Steps are needed to be taken to educate the people, to improve their socioeconomic status and also to provide better treatment facilities at grass root level.

  7. Suicide and the 'Poison Complex': Toxic Relationalities, Child Development, and the Sri Lankan Self-Harm Epidemic.

    Widger, Tom

    2015-01-01

    Suicide prevention efforts in Asia have increasingly turned to 'quick win' means restriction, while more complicated cognitive restriction and psychosocial programs are limited. This article argues the development of cognitive restriction programs requires greater consideration of suicide methods as social practices, and of how suicide cognitive schemata form. To illustrate this, the article contributes an ethnographically grounded study of how self-poisoning becomes cognitively available in Sri Lanka. I argue the overwhelming preference for poison as a method of self-harm in the country is not simply reflective of its widespread availability, but rather how cognitive schemata of poison-a 'poison complex'-develops from early childhood and is a precondition for suicide schemata. Limiting cognitive availability thus requires an entirely novel approach to suicide prevention that draws back from its immediate object (methods and causes of self-harm) to engage the wider poison complex of which suicide is just one aspect.

    Along with global environmental pollution resulting from economic development, heavy metal poisoning in children has become an increasingly serious health problem in the world. It can lead to renal injury, which tends to be misdiagnosed due to the lack of obvious or specific early clinical manifestations in children. Early prevention, diagnosis and intervention are valuable for the recovery of renal function and children's good health and growth. This paper reviews the mechanism of renal injury caused by heavy metal poisoning in children, as well as the clinical manifestations, diagnosis, and prevention and treatment of renal injury caused by lead, mercury, cadmium, and chromium.

    Attempted suicides and poisonings in pregnancy are a challenge for health care professionals because of the unknown effects of the toxic agent and the antidote therapy on the unborn. In case of intoxication, the malformation risk is often overestimated. In contrast, pertinent data show that the risk is not very high as long as the drug is not known as a teratogen and the mother's health is not substantially impaired. This applies to suicide attempts with acetaminophen, iron-containing products, and multidrug overdoses with psychopharmaceuticals as well as snake and spider bites and the ingestion of poisonous mushrooms. It is of utmost importance that the pregnant patient receives the same detoxification and supportive therapy following pertinent guidelines as a non-pregnant patient. The fetus should be followed-up by ultrasound with special focus on its vital parameters, movement pattern, and normal growth and organ differentiation. As long as the maternal health status is not substantially impaired, there is no indication to discuss elective termination of pregnancy "for toxicological reasons". PMID:22349530

  12. Hemlock alkaloids from Socrates to poison aloes.

    Science.gov (United States)

    Reynolds, Tom

    2005-06-01

    Hemlock (Conium maculatum L. Umbelliferae) has long been known as a poisonous plant. Toxicity is due to a group of piperidine alkaloids of which the representative members are coniine and gamma-coniceine. The latter is the more toxic and is the first formed biosynthetically. Its levels in relation to coniine vary widely according to environmental conditions and to provenance of the plants. Surprisingly, these piperidine alkaloids have turned up in quite unrelated species in the monocotyledons as well as the dicotyledons. Aloes, for instance, important medicinal plants, are not regarded as poisonous although some species are very bitter. Nevertheless a small number of mostly local species contain the alkaloids, especially gamma-coniceine and there have been records of human poisoning. The compounds are recognized by their characteristic mousy smell. Both acute and chronic symptoms have been described. The compounds are neurotoxins and death results from respiratory failure, recalling the effects of curare. Chronic non-lethal ingestion by pregnant livestock leads to foetal malformation. Both acute and chronic toxicity are seen with stock in damp meadows and have been recorded as problems especially in North America. The alkaloids derive biosynthetically from acetate units via the polyketide pathway in contrast to other piperidine alkaloids which derive from lysine.

    Jia Cao

    Full Text Available OBJECTIVE: To determine blood lead levels and to identify related risk factors among children in Shanghai; to explore the lead change trend of children after industrial transformation and to provide data for policy development to control environmental lead pollution in Shanghai. METHODS: A stratified-clustered-random sampling method was used. A tungsten atomizer absorption spectrophotometer was employed to determine blood lead levels. RESULTS: The arithmetic mean, geometric mean and median of blood lead levels of 0- to 6-year-old children from Shanghai were 22.49 µg/L, 19.65 µg/L and 19.5 µg/L, including 0.26% (6/2291 with concentrations ≥100 µg/L and 2.7% (61/2291 with concentrations ≥50 µg/L. Boys' levels (23.57 µg/L were greater than those of girls (21.2 µg/L. The blood lead levels increased with age. This survey showed that the Chongming district was the highest and Yangpu district was the lowest, this result is completely opposite with the earlier survey in Shanghai. Risk factors for lead contamination included housing environment, parents' education levels, social status, hobbies, and children's nutritional status. CONCLUSIONS: The blood lead levels of children in Shanghai were lower than the earlier data of Shanghai and those of published studies in China, but higher than the blood lead levels of developed countries. The blood lead levels of urban districts are higher than the central districts with the industrial transformation. Society and the government should take an active interest in childhood lead poisoning of urban areas.

    2015-06-01

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

  17. Activating Endogenous Neural Precursor Cells Using Metformin Leads to Neural Repair and Functional Recovery in a Model of Childhood Brain Injury

    Directory of Open Access Journals (Sweden)

    Parvati Dadwal

    2015-08-01

    Full Text Available The development of cell replacement strategies to repair the injured brain has gained considerable attention, with a particular interest in mobilizing endogenous neural stem and progenitor cells (known as neural precursor cells [NPCs] to promote brain repair. Recent work demonstrated metformin, a drug used to manage type II diabetes, promotes neurogenesis. We sought to determine its role in neural repair following brain injury. We find that metformin administration activates endogenous NPCs, expanding the size of the NPC pool and promoting NPC migration and differentiation in the injured neonatal brain in a hypoxia-ischemia (H/I injury model. Importantly, metformin treatment following H/I restores sensory-motor function. Lineage tracking reveals that metformin treatment following H/I causes an increase in the absolute number of subependyma-derived NPCs relative to untreated H/I controls in areas associated with sensory-motor function. Hence, activation of endogenous NPCs is a promising target for therapeutic intervention in childhood brain injury models.

    Abstract The aim of this study was to assess childhood lead exposure in a representative sample of Cairo, and to investigate the possible risk factors and sources of exposure. This cross-sectional study was conducted from November 2014 through April 2015. The target population was children aged 6 to 18 years, recruited into 4 groups, garbage city, moderate-living standard area, urban and suburban schools, and workshops in the city of Cairo. Blood lead levels (BLLs) and hemoglobin (Hb) concentrations were measured. Also, potential local environmental sources were assessed for hazardous lead contamination. Analysis on 400 participants has been carried out. A total of 113 children had BLLs in the range 10 to 20 μg/dL. Smoking fathers, housing conditions, playing outdoors, and exposure to lead in residential areas were significantly correlated with high BLLs. The mean values of hemoglobin were inversely correlated with BLLs. Children involved in pottery workshops had the highest BLLs and the lowest Hb values with a mean of (43.3 μg/dL and 8.6 g/dL, respectively). The mean value of environmental lead in workshop areas exceeded the recommended levels. Also, those values measured in dust and paint samples of garbage city were significantly high. Moreover, the mean lead levels in the soil samples were significantly higher in urban schools (P = 0.03) than the suburban ones. Childhood lead poisoning accounts for a substantial burden in Egypt, which could be preventable. Development of national prevention programs including universal screening program should be designed to reduce incidence of lead toxicity among children. PMID:26945415

    Full Text Available BACKGROUND & OBJECTIVES: Organophosphorus pesticide self-poisoning is a major clinical and public-health problem across much of rural Asia. The aim of this study was to analyze the patterns, the social factors and the clinical outcomes of OP poisoning at the Maharajah Institute Of Medical Sciences, Vizianagaram. MATERIALS AND METHODS: Fifty organophosphorous poisoning cases who were admitted to the MIMS, during the period of 1year (May 2013to June 2014, were studied. RESULTS: Fifty cases of OP poisoning were studied. In the present study, 56% cases were males, with the highest number of cases in the age group of 21 to 30 years (44%. Sixty four % belonged to married category. Sixty % of organophosphorous poisoning victims belonged to the farming community. Chlorpyrifos was consumed by 58% of the victims. 64 % of the OP poisoning victims were having family problems. Muscarinic and nicotinic symptoms were prevalent in majority of victims. 64 % people had recovery and Intermediate syndrome was observed in 36% cases of organophosphorous poisoning. CONCLUSION: There was a high incidence of OP poisoning related mortality in this region. The OP compounds were readily available at low costs in the market. A time of stress and frustration can lead to their use as a common poison to commit suicide with.

    Garcelon, D.K.; Thomas, N.J.

    1997-01-01

    A 12-year-old female bald eagle (Haliaeetus leucocephalus) was found in May 1993 on Santa Catalina Island, California (USA), in a debilitated condition, exhibiting ataxia and tremors; it died within hours. On necropsy, the bird was emaciated but had no evidence of disease or physical injury. Chemical analyses were negative for organophosphorus pesticides and lead poisoning. High concentrations of DDE (wet weight basis) were found in the brain (212 ppm), liver (838 ppm), and serum (53 ppm). Mobilization of DDE, from depleted fat deposits, probably resulted in the lethal concentration in the eagle's brain.

It has been found, however, that liver from some species such as burbot, from some lakes, should not be eaten. These lakes are found to contain higher levels of PCB (polychlorinated biphenyls) and DDT (dichlorodiphenyltrichloroethane). Previously, pregnant or breast-feeding women anywhere in Norway have been advised not to eat pike, large perch or large trout because of too much mercury. Other people should not eat these species more often than once per month. In general, the level of organic environmental poisons is higher in the southern part of the country than in the northern part. The sediments of the lakes in large parts of South Norway are contaminated with lead, mercury and cadmium as compared with the conditions before the industrial revolution. However, the level of metals in the lake sediments are relatively low, and these substances are unlikely to appear in the food chain, by and large. The anthropogenic emission of lead was insignificant before the industrial revolution. The exception of lead from German mining industry in the 1700s

    2015-01-01

    Paracetamol poisoning is the commonest overdose seen in the UK. The management of patients with paracetamol poisoning has been little changed for the past 40 years, with a weight related dose of antidote (acetylcysteine) and treatment based on nomograms relating paracetamol concentration to time from ingestion. In 2012 the UK Commission on Human Medicines recommended a revision of the nomogram, following the death of a young woman, lowering the treatment threshold for all patients. As a resul...

  10. Unintentional Childhood Injury Patterns, Odds, and Outcomes in Kampala City: an analysis of surveillance data from the National Pediatric Emergency Unit

    Full Text Available BACKGROUND: Unintentional Childhood Injuries pose a major public health challenge in Africa and Uganda. Previous estimates of the problem may have underestimated the childhood problem. We set to determine unintentional childhood injury pattern, odds, and outcomes at the National Paediatric Emergency unit in Kampala city using surveillance data. METHODS: Incident proportions, odds and proportional rates were calculated and used to determine unintentional injury patterns across childhood (1-12 years. RESULTS: A total of 556 cases recorded between January and May 2008 were analyzed: majority had been transported to hospital by mothers using mini-buses, private cars, and motorcycles. Median distance from injury location to hospital was 5 km. Homes, roads, and schools were leading injury locations. Males constituted 60% of the cases. Play and daily living activities were commonest injury time activities. Falls, burns and traffic accounted for 70.5% of unintentional childhood injuries. Burns, open wounds, fractures were commonest injury types. Motorcycles, buses and passenger-cars caused most crashes. Play grounds, furniture, stairs and trees were commonest source of falls. Most burn injuries were caused by liquids, fires and hot objects. 43.8% of cases were admitted. 30% were discharged without disability; 10%, were disabled; 1%, died. Injury odds and proportional incidence rates varied with age, place and cause. Poisoning and drowning were rare. Local pediatric injury priorities should include home, road and school safety. CONCLUSIONS: Unintentional injuries are common causes of hospital visit by children under 13 years especially boys. Homes, roads and educational facilities are commonest unintentional injury sites. Significant age and gender differences exist in intentional injury causation, characteristics and outcomes. In its current form, our surveillance system seems inefficient in capturing poisoning and drowning. The local prevention

    THE SALMON-POISONING FLUKE is misnamed as far as the fish culturist is concerned, for the disease affects dogs, not fish. There is considerable evidence, however, that fish may also suffer from the complex chain of events leading from snail to dying dog. Histological studies indicate that young salmon and trout may be severely damaged by the encysted stage of the fluke.

    Full Text Available Context We report a case of massive poisoning with meprobamate leading to acute pancreatitis. Case report A 43-year-old patient with a history of schizophrenia and multiple suicide attempts was admitted to the intensive care unit for severe poisoning with meprobamate (voluntary ingestion of 60 g. On admission, the patient was deeply comatose with low blood pressure and hypothermia. Laboratory analysis revealed leukocytosis and high lipase and amylase serum levels. There was no eosinophilia. Abdominal computed tomography showed pancreatitis grade A. The patient was intubated and ventilated, and intravenous dopamine was infused. The patient regained consciousness and was extubated five days later. Improvement in pancreatic tests was noted several days later. The outcome was favorable. Discussion According to the Naranjo probability scale, meprobamate-induced acute pancreatitis was probable. Acute pancreatitis in meprobamate poisoning is exceptional. The pathogenesis of pancreatitis-induced meprobamate poisoning may be explained by two mechanisms: stimulation of pancreatic secretion secondary to cholinergic activation and pancreatic ductal hypertension. Conclusions The signs of severe meprobamate toxicity are numerous including cardiovascular and central nervous symptoms. Acute pancreatitis should also be added as a possible manifestation of meprobamate poisoning.

  14. Topoisomerase II poisoning by indazole and imidazole complexes of ruthenium

    2001-06-01

    Trans-imidazolium (bis imidazole) tetrachloro ruthenate (RuIm) and trans-indazolium (bis indazole) tetrachloro ruthenate (RuInd) are ruthenium coordination complexes, which were first synthesized and exploited for their anticancer activity. These molecules constitute two of the few most effective anticancer ruthenium compounds. The clinical use of these compounds however was hindered due to toxic side effects on the human body. Our present study on topoisomerase II poisoning by these compounds shows that they effectively poison the activity of topoisomerase II by forming a ternary cleavage complex of DNA, drug and topoisomerase II. The thymidine incorporation assays show that the inhibition of cancer cell proliferation correlates with topoisomerase II poisoning. The present study on topoisomerase II poisoning by these two compounds opens a new avenue for renewing further research on these compounds. This is because they could be effective lead candidates for the development of more potent and less toxic ruthenium containing topoisomerase II poisons. Specificity of action on this molecular target may reduce the toxic effects of these ruthenium-containing molecules and thus improve their therapeutic index.

  15. Neurotoxic Shellfish Poisoning

    Directory of Open Access Journals (Sweden)

    Roberta Hammond

    2008-07-01

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

    Ligabue-Braun, Rodrigo; Carlini, Célia Regina

    2015-06-01

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

  1. Nitric Acid Poisoning: Case Report

    International Nuclear Information System (INIS)

    Nitric acid (HNO3) is a corrosive fluid that, when in contact with reducing agents, generates nitrogen oxides that are responsible for inhalation poisoning. We present two cases of poisoning from nitric acid gas inhalation resulting from occupational exposure. Imaging findings were similar in both cases, consistent with adult respiratory distress syndrome (ARDS): bilaterally diffuse alveolar opacities on the chest X-ray and a cobblestone pattern on computed tomography (CT).one of the patients died while the other evolved satisfactorily after treatment with n-acetyl cysteine and mechanical ventilation. The diagnosis of nitric acid poisoning was made on the basis of the history of exposure and the way in which the radiological findings evolved.

    Full Text Available São revisados os trabalhos que, a partir de 1975,estudaram a ocorrência de manifestações neurológicas centrais e periféricas em trabalhadores ocupacionalmente expostos ao chumbo, que apresentavam níveis de exposição supostamente insuficientes para causarem Saturnismo. A partir da revisão realizada é sugerido que os limites de tolerância biológica utilizados em nosso meio para firmar o diagnóstico de intoxicação profissional pelo chumbo devam ser revistos. Tal sugestão baseia-se na existência de evidências bem estabelecidas que apontam disfunções da condução nervosa periférica e central, além de alterações de várias funções nervosas superiores, em trabalhadores profissionalmente expostos ao chumbo que apresentam indicadores de efeito biológico e indicadores de exposição inferiores aos limites estabelecidos pela legislação brasileira.This article reviews studies performed since 1975 on the occurrence of central and peripheral neurological manifestations in low-level lead exposure. The review shows that in many workers exposed to lead who present indications of both biological effects and exposure below the limits established by the Brazilian laws, abnormalities are found in peripheral nerve conduction velocity and also in several central nervous system functions. The study thus suggests that the threshold values used in Brazil to confirm lead poisoning should be revised.

    2002-03-01

    Full Text Available Introduction. Lead poisoning is a major problem in environmental health. Exposure can occur via air, soil, food and water. Occupational exposure is the most common source of lead poisoning in adults. Lead miners are exposed to an additional source of poisoning in long term. Hair analysis may be used to evaluate chronic lead toxicity. This study compare the hair lead concentration in Nakhlak lead miners and Mohammadieh people who live 130 km far from the lead mine. Methods. Hair samples from 24 Nakhlak lead miners and 26 adult men of Mohammadieh village were gathered, washed by detergent and distilled water and dissolved by wet digestion. Lead concentrations of the samples were measured by flame atomic absorption spectroscopy. Results. There was a significant difference between hair lead concentration of Nakhlak lead miners and Mohammadieh people (P < 0.001. The mean of lead concentrations were 52.43±27.7 µg/g (mean ± SD and 17.32±3.43 µg/g hair of the lead mine workers and the Mohammadieh people, respectively. There was also a significant regression between the number of exposure years and the lead concentration of hair in Nakhlak lead miners (P < 0.001, r=0.8. Discussion. Presence of lead compounds in work environment especially in the air may be an important factor for the difference between hair lead concentration of Nakhlak lead miners and Mohammadieh people. However, the hair lead concentration in Mohammadieh people is also reasonably high. It means that these people are also exposed to lead through the other sources e.g. food, soil, water and air.

    The Act on Nature Conservation of 16.04.2004 (Official Journal, 2004, No 92, item 880) imposes on private individuals the duty to register some animals. The data collected by Kraków municipal authorities and delivered to the Poison Information Centre (Colleglum Medicum, Jagiellonian University) indicate that there are following species in private hands in the city and its surroundings: 11 individuals of Naja naja, 2--Hydrodynates gigas and 55-- Dendrobates spp. According to these information the employees of the PIC elaborated the advice on the treatment of specific animals' poisoning. In the period May 2003 - May 2004 (before the above Act came into force) there were 143 individuals from Brachypelma genus and 3 scorpions (Pandinus imperator) registered in Krakow. These species produce venoms which take local effect. According to art. 64 (1) of the above Act it is compulsory to register amphibians, reptiles, birds and mammals. However, it would be desirable to introduce the duty to register also dangerous species of invertebrates and fishes. It would provide the complete list of poisonous animals kept in private hands. Thus, it would be possible to estimate any possible threats and to elaborate adequate treatment in case of specific animals' poisoning.

    The Act on Nature Conservation of 16.04.2004 (Official Journal, 2004, No 92, item 880) imposes on private individuals the duty to register some animals. The data collected by Kraków municipal authorities and delivered to the Poison Information Centre (Colleglum Medicum, Jagiellonian University) indicate that there are following species in private hands in the city and its surroundings: 11 individuals of Naja naja, 2--Hydrodynates gigas and 55-- Dendrobates spp. According to these information the employees of the PIC elaborated the advice on the treatment of specific animals' poisoning. In the period May 2003 - May 2004 (before the above Act came into force) there were 143 individuals from Brachypelma genus and 3 scorpions (Pandinus imperator) registered in Krakow. These species produce venoms which take local effect. According to art. 64 (1) of the above Act it is compulsory to register amphibians, reptiles, birds and mammals. However, it would be desirable to introduce the duty to register also dangerous species of invertebrates and fishes. It would provide the complete list of poisonous animals kept in private hands. Thus, it would be possible to estimate any possible threats and to elaborate adequate treatment in case of specific animals' poisoning. PMID:16225138

  8. Intentional Ethylene Glycol Poisoning Increase after Media Coverage of Antifreeze Murders

    Directory of Open Access Journals (Sweden)

    Morgan, Brent

    2011-07-01

    Full Text Available Background: The media can have a profound impact on human behavior. A sensational murder by ethylene glycol (EG poisoning occurred in our state. The regional media provided extensive coverage of the murder. We undertook this investigation to evaluate our incidence of EG poisoning during the timeframe of before the first report linking a death to ethylene glycol to shortly after the first murder trial.Methods: Descriptive statistics and linear regression were used to describe and analyze the number of EG cases over time. A search of the leading regional newspaper’s archives established the media coverage timeline.Result: Between 2000 and 2004, our poison center (PC handled a steady volume of unintentional exposures to EG [range: 105–123 per year, standard deviation (SD=7.22]. EG exposures thought to be suicidal in intent increased from 12 cases in 2000 to 121 cases in 2004. In the 19 months prior to the first media report of this story, our PC handled a mean of 1 EG case with suicidal intent per month [range: 0–2, SD=.69]. In the month after the first media report, our PC handled 5 EG cases with suicidal intent. When media coverage was most intense (2004, our PC received a mean of 10 EG suicidal-intent calls per month [range: 5–17, SD=3.55]. Although uncommon, reports of malicious EG poisonings also increased during this same period from 2 in 2000 to 14 in 2004.Conclusion: Media coverage of stories involving poisonings may result in copycat events, applicable to both self-poisonings and concern for malicious poisonings. Poison centers should be aware of this phenomenon, pay attention to local media and plan accordingly if a poisoning event receives significant media coverage. The media should be more sensitive to the content of their coverage and avoid providing “how to” poisoning information. [West J Emerg Med. 2011;12(3:296-299.

    Approximately 10% of children are obese. Twin and adoption studies demonstrate a large genetic component to obesity, especially in adults. However, the increasing prevalence of obesity over the last 20 years can only be explained by environmental factors. In most obese individuals, no measurable differences in metabolism can be detected. Few children engage in regular physical activity. Obese children and adults uniformly underreport the amount of food they eat. Obesity is particularly related to increased consumption of high-fat foods. BMI is a quick and easy way to screen for childhood obesity. Treating childhood obesity relies on positive family support and lifestyle changes involving the whole family. Food preferences are influenced early by parental eating habits, and when developed in childhood, they tend to remain fairly constant into adulthood. Children learn to be active or inactive from their parents. In addition, physical activity (or more commonly, physical inactivity) habits that are established in childhood tend to persist into adulthood. Weight loss is usually followed by changes in appetite and metabolism, predisposing individuals to regain their weight. However, when the right family dynamics exist--a motivated child with supportive parents--long-term success is possible.

    2016-06-01

    Organophosphorus (OP) pesticide poisoning is a leading cause of morbidity and mortality in the developing world, affecting an estimated three million people annually. Much of the morbidity is directly related to muscle weakness, which develops 1-4 days after poisoning. This muscle weakness, termed the intermediate syndrome (IMS), leads to respiratory, bulbar, and proximal limb weakness and frequently necessitates the use of mechanical ventilation. While not entirely understood, the IMS is most likely due to persistently elevated acetylcholine (ACh), which activates nicotinic ACh receptors at the neuromuscular junction (NMJ). Thus, the NMJ is potentially a target-rich area for the development of new therapies for acute OP poisoning. In this manuscript, we discuss what is known about the IMS and studies investigating the use of nicotinic ACh receptor antagonists to prevent or mitigate NMJ dysfunction after acute OP poisoning.

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

    Plant poisoning is not uncommon in Thailand. The objective of this study was to determine the incidence, type, clinical manifestations, severity and outcomes of plant poisoned patients in Thailand over a 10-year period. We retrospectively reviewed data from the Ramathibodi Poison Center Toxic Exposure Surveillance System for 2001-2010. A total of 2,901 poisonous plant exposure cases were identified, comprising 3.1% of the 92,392 poison cases recorded during the study period. This was the fifth most common type of poisoning recorded. Children aged Jatropha curcas (physic nut) comprising 54.1% of these. Most patients had only minor signs and symptoms. The mortality rate among the total plant poisoning cases was 0.9%, with 26 deaths. Thirteen deaths occurred in children aged Jatropha curcas was the most common cause of poisoning and Manihot esculenta was the most common cause of death. Public education is important to minimize these poisonings. PMID:26867365

    N-acetylcysteine (NAC) is used widely and effectively in oral and intravenous forms as a specific antidote for acetaminophen poisoning. Here we report a rare case of iatrogenic NAC overdose following an error in preparation of the solution, and describe its clinical symptoms. Laboratory results and are presented and examined. A 23-year-old alert female patient weighing 65 kg presented to the emergency ward with weakness, lethargy, extreme fatigue, nausea, and dizziness. She had normal arterial blood gas and vital signs. An excessive dosage of NAC over a short period of time can lead to hemolysis, thrombocytopenia, and acute renal failure in patients with normal glucose-6-phosphate dehydrogenase, and finally to death. Considering the similarity between some of the clinical symptoms of acetaminophen overdose and NAC overdose, it is vitally important for the administration phases and checking of the patient's symptoms to be carried out attentively and cautiously.

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

  1. Childhood vitiligo

    2012-01-01

    Full Text Available Childhood vitiligo is often encountered in dermatological practice. When present in infancy or early childhood, various nevoid and hereditary disorders are to be differentiated. In many cases, familial aggregation of the disease is seen and other autoimmune disorders may be associated. Segmental presentation is more common, and limited body surface area involvement is usual in this age group. Children with vitiligo often suffer from anxiety and depression because of their unusual appearance. Management of vitiligo in children is difficult as therapeutic options are restricted when compared to that in adult patients. Selection of treatment should be careful in these patients with the aim to achieve best results with minimal side effects as well as relieving patients′ and parents′ anxiety.

This condition should be considered in the evaluation of children with vomiting and abdominal pain, because it can cause significant morbidity and mortality. Clinical suspicion is required to make the diagnosis, especially when the serum amylase concentration is normal. Recurrent pancreatitis may be familial as a result of inherited biochemical or anatomic abnormalities. Patients with hereditary pancreatitis are at high risk for pancreatic cancer.

    1997-01-01

    We monitored lead poisoning from the ingestion of spent lead pellets in sentinel mallards (Anas platyhrynchos) at the Sacramento National Wildlife Refuge (SNWR), Willows, California for 4 years (1986-89) after the conversion to steel shot for waterfowl hunting on refuges in 1986. Sentinel mallards were held in 1.6-ha enclosures in 1 hunted (P8) and 2 non-hunted (T19 and TF) wetlands. We compared site-specific rates of lead exposure, as determined by periodic measurement of blood lead concentrations, and lead poisoning mortality between wetlands with different lead pellet densities, between seasons, and between male and female sentinels. In 1986, the estimated 2-week rate of lead exposure was significantly higher (P 2,000,000 pellets/ha), than in those with lower densities of lead pellets, T19 (18.1%; 173,200 pellets/ha) and TF (0.9%; 15,750 pellets/ha). The probability of mortality from lead poisoning was also significantly higher (P < 0.01) in sentinel mallards enclosed in P8 (0.25) than T19 (0) and TF (0) in 1986 and remained significantly higher (P < 0.001) during the 4-year study. Both lead exposure and the probability of lead poisoning mortality in P8 were significantly higher (P < 0.001) in the fall of 1986 (43.8%; 0.25), before hunting season, than in the spring of 1987 (21.6%; 0.04), after hunting season. We found no significant differences in the rates of lead exposure or lead poisoning mortality between male and female sentinel mallards. The results of this study demonstrate that in some locations, lead exposure and lead poisoning in waterfowl will continue to occur despite the conversion to steel shot for waterfowl hunting.

  8. Paracetamol poisoning: beyond the nomogram.

    Science.gov (United States)

    Bateman, D Nicholas

    2015-07-01

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

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

    The toxicity of the weed-killer paraquat is related to the formation of superoxyde radicals responsible of a progressive and usually lethal pulmonary fibrosis. Recognition of lipid peroxidation of membrane bilayers by free radicals as the causative factor pointed to oxygen as an important cofactor in the severity of paraquat poisoning. It has been shown that any FiO2 over 21% accelerates this process and increases the the mortality of rats and humans. FiO2 21% gave a significant reduction of mortality in rats (DOUZE 1976). We proposed this therapy (1978-1879) in 6 cases of paraquat poisoning. It was conducted with induction of a barbiturate coma, hypothermia, curarisation and hypo-oxygenation (FiO2 around 14% thanks to the adjunction of nitrogen to assisted ventilation). In 5/6 patients, these technics did not prevent the evolution towards death. This evolution was in fact predicted, according the following prognostic factors: suicide, more than a mouthful ingestion, oesophago-gastric burns detected by endoscopy, organic renal failure, high plasma paraquat level. Associated methods of elimination (Fuller's earth, provoked diarrhea, furosemide, hemoperfusion and hemodialysis) did not change the early established prognosis. The only survival was observed in an accidental poisoning with undetectable plasma paraquat and isolated oral burns: the herbicide had been probably spit out. This survival cannot be related to hypo-oxygenation. This failure is not definitive, according to us: this therapy should be undertaken only after minimal, accidental poisoning possibly evolving to pulmonary fibrosis. It appears unuseful in massive, suicidal poisonings, leading readily to a lethal circulatory failure. PMID:6612725

    Most mushroom intoxications become evident within 12 hours with vomiting and diarrhea. They can be divided into incidents with a short latency (less than four hours) and incidents with a long latency (longer than four hours). As a rule of thumb amatoxin poisonings must be considered in case of symptoms appearing with a long latency (8-12-18 h), especially after consumption of non-controlled wild mushrooms. Shorter latencies do not exclude amatoxin poisoning. Large meals of mushrooms, which are rich in chitin, mixed meals and individual factors, may shorten latency and disguise amatoxin poisoning. Any vomiting and diarrhea after mushroom consumption is suspicious. Unless the mushrooms are not to be identified within 30 minutes by an expert, specific treatment for amatoxin poisoning must be started. Identification shall be achieved by macroscopic or microscopic means; and urine analysis for amatoxins are crucial. By commencing treatment before analysis, mortality rates may be as low as 5%. Current standards in amatoxin poisoning treatment can be obtained at the Swiss Toxicological Information Centre (Phone 145), where contacts to mycologists are available as well. Emergency mycologists are listed on the website www.vapko.ch. Of the 18 different syndromes we present the most common and most important in Switzerland. In an overview all of them are listed. Early gastrointestinal syndrome with its short latency of less than 4 h and indigestion with a very variable latency are the most common. Psychotropic symptoms after consumptions of fly agaric and panther cap are rare, in case of psilocybin-containing mushrooms, symptoms are frequent, but hardly ever lead to medical treatment. In case of renal failure and rhabdomyolysis of unknown origin, completing a patient's history by questioning nutritional habits might reveal causal relationship with ingestion of orellanin-containing mushrooms or tricholoma equestre respectively.

    Carbon monoxide (CO) is the leading cause of death due to poisoning. Although uncommon, CO poisoning does occur during pregnancy and can result in fetal mortality and neurological malformations in fetuses who survive to term. Uncertainty arises regarding the use of hyperbaric oxygen (HBO) as a treatment for the pregnant patient because of possible adverse effects on the fetus that could be induced by oxygen at high partial pressures. While the dangers of hyperoxia to the fetus have been demonstrated in animal models, careful review of animal studies and human clinical experience indicates that the short duration of hyperoxic exposure attained during HBO therapy for CO poisoning can be tolerated by the fetus in all stages of pregnancy and reduces the risk of death or deformity to the mother and fetus. A case is presented of acute CO poisoning during pregnancy that was successfully treated with HBO. Recommendations are suggested for the use of HBO during pregnancy.

    Full Text Available Acute agrochemical poisoning is a leading cause of mortality and morbidity in India. Pendimethalin (herbicide and Pancycuron (fungicide are frequently used worldwide and considered quite a remarkably safe one for humans. Their acute toxicity is not yet widely known. Here we are reporting cases of their acute poisoning in young. To the best of our knowledge not a single such case of their poisoning has been reported so far in india. Such poisoning by entirely new compounds is an emerging problem in the tropics. In this communication we are reporting such unusual and entirely new toxicities and trying to highlight the need of their early recognition and timely management in rural regions where health facilities are already at the stake.

    Childhood iron deficiency has a high incidence in Pakistan. Some but not all studies have shown that dietary iron deficiency may cause increased absorption of lead as both compete for the same transporters in the small intestine. Therefore, children in Pakistan, residing in heavily polluted cities like Karachi may be prone to lead poisoning. This hypothesis was tested by investigating blood and hair lead concentrations in children from Karachi who were divided into four groups of iron status; normal, borderline iron deficiency, iron deficiency and iron deficiency anaemia. A prospective observational study was conducted where 269 children were categorized into four groups of iron status using the World Health Organization criteria and one based on soluble transferrin receptor measurements. Blood iron status was determined using a full blood count, serum iron, ferritin, transferrin saturation and soluble transferrin receptor measurements. Blood lead was determined by graphite atomic absorption spectroscopy, whereas hair lead was assessed using an inductively coupled plasma atomic emission spectroscopy technique. Blood lead concentrations were significantly higher in children with iron deficiency anaemia (mean [95% confidence intervals] were 24.9 [22.6-27.2] {mu}g/dL) compared to those with normal iron status (19.1 [16.8-21.4] {mu}g/dL) using WHO criteria. In contrast, hair lead content was not significantly different in children of different iron status. Our findings reinforce the importance of not only reducing environmental lead pollution but also the development of national health strategies to reduce childhood iron deficiency in Pakistan.

    Full Text Available Psoriasis is a common dermatosis in children with about one third of all patients having onset of disease in the first or second decade of life. A chronic disfiguring skin disease, such as psoriasis, in childhood is likely to have profound emotional and psychological effects, and hence requires special attention. Psoriasis in children has been reported to differ from that among adults being more frequently pruritic; plaque lesions are relatively thinner, softer, and less scaly; face and flexural involvement is common and guttate type is the characteristic presentation. Whether onset in childhood predicts a more severe form of psoriasis is a matter of controversy, it may cause significant morbidity particularly if it keeps relapsing. Most children have mild form of psoriasis which can be generally treated effectively with topical agents such as emollients, coal tar, corticosteroids, dithranol, calcipotriol etc. according to age and the sites affected. Narrow band UVB is the preferred form of phototherapy in children for moderate to severe disease or in patients not responding to topical therapy alone. Systemic therapies are reserved for more severe and extensive cases that cannot be controlled with topical treatment and/or phototherapy such as severe plaque type, unstable forms like erythrodermic and generalized pustular psoriasis and psoriatic arthritis. There are no controlled trials of systemic therapies in this age group, most experience being with retinoids and methotrexate with favorable results. Cyclosporine can be used as a short-term intermittent crisis management drug. There is an early promising experience with the use of biologics (etanercept and infliximab in childhood psoriasis. Systemic treatments as well as phototherapy have limited use in children due to cumulative dose effects of drugs, low acceptance, and risk of gonadal toxicity. More evidence-based data is needed about the effectiveness and long-term safety of topical

    Children are at increased risk for various causes of injury from accidents. Accidents are, by far, the leading cause of death among children and adolescents. The aim of this study is to evaluate the lethal childhood accidents in İstanbul by age groups. Reports of autopsies performed between 2001 and 2005 in the Morgue Department of the Council of Forensic. Medicine in Istanbul (n :16853) are examined retrospectively. 833 deaths from accidents in children aged 0-18 years are investigated into the study. The parameters of age, gender, types of accidents and causes of death are evaluated. The accidents account for 47.3% of the deaths among children aged 0-18 years. Of 833 cases, 601 (73%) are male and 232 (27%) are female. The female to male ratio is 1/2.6. The highest rate of death from accidents is at the group of 15-18 years. The primary causes of accidental childhood deaths are motor vehicle accidents (23.1%), followed by drowning (20,1%), poisoning (15.7%), and fall from height (15.5%). The incidence and types of trauma vary with socio-economic status and culture. İstanbul, where this study is conducted in, has approximately 3000 autopsy number annually. Therefore, it provides an important database.

    Full Text Available BACKGROUND AND OBJECTIVES: Organophosphorus compound poisoning is the most common medico toxic emergency in India the increase in pesticide use in agriculture has paralleled the increase in the use of these products for deliberate self-warm. Respiratory failure is the most common complication of OP poisoning leading to death. Early recognition and prompt ventilator support may improve survival. Owing to limited availability of resources, all OP poisoning patients are not managed in ICUs in Indian setup. It is therefore important that clinical features and criteria to predict the need for ventilator support be identified at initial examination. Hence this study was undertaken to assess the severity of organophosphorus compound poisoning both clinically by using Peradeniya scoring and by estimating serum choline esterase levels. METHODS: Cross sectional study was done at basaveswar teaching and general hospital attached to MR Medical College. Cases with history of exposure to organophosphorus compound within previous 24 hours were chosen after applying inclusion and exclusion criteria. Patients were evaluated for Peradeniya OP poisoning scale and serum cholinesterase levels for assessment of severity of poisoning. Serum cholinesterase levels and Peradeniya OP poisoning scale were studied to predict the need for ventilator support. The results were analyzed using Chi-square test. STATISTICAL ANALYSIS: It was done using pearson’s chi square test. RESULTS: In this study requirement of ventilator support was seen in 36% of patients. Mortality in our study was 18%. Only 15.6% of patients with mild grade of poisoning according to Peradeniya OP poisoning scale required ventilator support, whereas 84.4% did not require ventilator support. Most of patients with moderate (70.6% and severe poisoning (100% according to Peradeniya OP poisoning scale required ventilator support. 93.7% of patients with serum cholinesterase levels more than 50% did not require

    Psoriasis is a common skin disease in infants, children, and adolescents. A review of the clinical, epidemiologic, genetic, and therapeutic aspects of childhood psoriasis is presented. Population studies indicate that the first signs of psoriatic lesions occur in the pediatric age group, birth to 18 years of age, and that both genetic and environmental factors interact to precipitate the development of psoriasis. Koebner reactions are the result of external or internal triggering factors, such as physical injury to the skin, low humidity, and certain drugs. The most frequently observed variant to psoriasis is the plaque type, followed by guttate psoriasis, and juvenile psoriatic arthritis. Pustular psoriasis and erythrodermic psoriasis are rare forms of the disease, but are seen in children from infancy to adolescence. The scalp is the most frequently affected site of involvement in pediatric psoriasis, followed by the appearance of lesions on the extensor surfaces of the extremities, trunk, and nails. Although not common in adult psoriasis, the face and ears are often involved. Topical medications such as corticosteroids, calcipotriol, coal tar preparations, anthralin formulations, and ultraviolet B are recommended in monotherapy or in combination therapy, whereas psoralen plus ultraviolet A, methotrexate, and retinoids should only be administered in crisis situations. The treatment objectives in childhood psoriasis are to preserve skin surfaces, to afford physical relief from the disease, and to employ treatments that do not endanger the health or future development of the child.

    Hydrofluoric acid is a highly dangerous substance with industrial and domestically appliances. Clinical manifestations of poisoning depend on exposure mechanism, acid concentration and exposed tissue penetrability. Gastrointestinal tract symptoms do not correlate with injury severity. Patients with history of hydrofluoric acid ingestion should undergo an endoscopy of the upper gastrointestinal tract. Intoxication requires immediate intervention because systemic toxicity can take place. We present a 5 year old girl who accidentally swallowed 5 ml of 20% hydrofluoric acid. We performed gastrointestinal tract endoscopy post ingestion, which revealed erythematous esophagus and stomach with erosive lesions. Two months later, same study was performed and revealed esophagus and stomach normal mucous membrane.

    Full Text Available Haloperidol, a butyrophenone neuroleptic drug, is an antipsychotic used in the treatment of adult schizophrenia and mania. It is used in children with neurological disorders like chorea and developmental disorders such as hyperactivity. With the advent of newer selective neuroleptics use of haloperidol is now on decline. However, in adults it is still the preferred drug especially in resource challenged settings. Extrapyramidal reactions occur frequently with haloperidol predominantly as parkinsonian symptoms. There are few case reports of accidental haloperidol poisoning in children and this one of them.

    This retrospective study evaluated the frequency, etiology, therapy and prognosis of animal poisoning registered from 2003 to 2012. The relevant cases reported to the Swiss Toxicological Information Center (STIC) were compared with those from previously examined periods. Human medicines not approved for animals and pesticides represented the most common causes of poisoning in dogs. Novel cases occurred as a consequence of the exposure of dogs to ricinus fertilizers, grape residues from wineries, pepper lachrymatory spray and dry bouillon. Cats are still freequently poisoned by pyrethroid drugs that should be administered only to dogs. Agrochmical products are the main source of toxicities in farm animals. Most poisonings in horses and exotic animals took place due to toxic plants. In addition, two tigers died of a secondary poisoning after ingestion of meat from euthanized calves. PMID:26753326

    International Nuclear Information System (INIS)

    The results of a theoretical investigation into the possible relaxation of criticality concentration limits in wet chemical reprocessing plants, due to the introduction of boron poisoning, are reported. The following systems were considered: 1. 1 in. stainless steel tubes filled with boron carbide at various pitches in homogeneous mixtures of 239Pu (NO3)4, 5H2O and water. 2. 1 in. and 2 in borosilicate glass Raschig rings in homogeneous mixtures of 239Pu (NO3)4, 5H2O and water. 3. The concentration of natural boron required for k∞ = 1 in homogeneous mixtures of 239Pu-B-H2O. The method of calculation was Monte Carlo using the GEM code with Nuclear Data File cross-sections. The Raschig rings used are those commercially available. The core model consisted of a cubic arrangement of unit cubes of solution within each of which a Raschig ring was centrally placed. The arrangement was such that the rings were regularly stacked with axes parallel, but the side of the unit cube was fixed to preserve the random packing density. Comparison is made with other reported results on boron poisoning. (author)

  7. The treatment of acetaminophen poisoning

    Energy Technology Data Exchange (ETDEWEB)

    Prescott, L.F.; Critchley, J.A.

    1983-01-01

    Acetaminophen has become a very popular over-the-counter analgesic in some countries and as a result it is used increasingly as an agent for self-poisoning. Without treatment only a minority of patients develop severe liver damage and 1 to 2% die in hepatic failure. Until Mitchell and his colleagues discovered the biochemical mechanisms of toxicity in 1973 there was no effective treatment. They showed that the metabolic activation of acetaminophen resulted in the formation of a reactive arylating intermediate, and that hepatic reduced glutathione played an essential protective role by preferential conjugation and inactivation of the metabolite. Early treatment with sulphydryl compounds and glutathione precursors has been dramatically effective in preventing liver damage, renal failure, and death following acetaminophen overdosage. It seems likely that these agents act primarily by stimulating glutathione synthesis. Inhibition of the metabolic activation of acetaminophen is another potential therapeutic approach that has not yet been put to the test clinically. The clinical management of acetaminophen poisoning has been transformed and it is particularly gratifying to have effective treatment based on a well established biochemical mechanism of toxicity. It is likely that effective treatment will be developed for toxicity caused through similar mechanisms by other agents.

    This study was undertaken to determine the teratogenic potential of methylmercury on chick embryogenesis. Methylmercuric chloride was dissolved in sodium bicarbonate (0.2%) and administered to the chick embryos at doses ranging from 0.0009 to 0.010 mg per egg. The injections were made at days 2 and 3 on incubation (Groups A and B). All the embryos including controls were examined on the 7th day of incubation. Methylmercury poisoning was observed to be both embryolethal and teratogenic. Within the two groups, embryolethality was higher in Group A. The following congenital abnormalities were observed: exencephaly, shortened and twisted limbs, microphthalmia, shortened and twisted neck, beak abnormalities, everted viscera, reduced body size and hemorrhage all over the body. Exencephaly and limb abnormalities were very common. No differences in the incidence and types of gross abnormalities within both the groups (A and B) were noted. The incidence of malformations among the controls was low. The results of present investigation show that methylmercury poisoning is both embryolethal and teratogenic to early chick embryogenesis.

  14. How lead loses its toxicity to plants

    Directory of Open Access Journals (Sweden)

    Małgorzata Wierzbicka

    2014-02-01

    Full Text Available This paper is a brief review of the problem of lead-in the environment, particularly constitutional tolerance to lead about which little is known. Taking Allium cepa L. roots as a model it has been shown that after an initial phase in which lead is toxic to cells, defence processes appear with the results that lead is no longer poisonous. The lead which penetrates into the root symplast is detoxified in vacuoles, cell walls and dictiosomal vesicles. Initial cells of the meristem (quescent centre which play a basic role in the root regeneration processes are protected against lead penetration. This surprising result is in agreement with the absence of any symptoms of lead poisoning in plants growing in natural conditions, and suggests that there is a defence mechanism specific only for plant cells.

    2016-01-01

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

    2012-08-01

    We present two events of carbon monoxide (CO) poisoning, which spread out through ventilation pipes to kill or injure neighbors. This is a previously undocumented poisoning process. In the first event, three people died and eight others suffered CO poisoning from a gas-powered water heater in an apartment building. Similar to the first event, three people expired and three others were injured by CO poisoning in the second event. We subsequently determined the cause of these tragedies were due to obstructions at the openings of ventilation pipes. CO is one of the most common causes of poisoning worldwide and these cases often result in tragedy. Early recognition of CO poisoning resulting from obstructed ventilation pipes will facilitate proper management and prevent possible lethal disasters. Additionally, all clinicians and other paramedical personnel ought to raise the suspicion of chemical-related casualties when encountering clusters of patients from a single locale.

    Metal phosphides in general and aluminium phosphide in particular are potent insecticides and rodenticides. These are commercially used for protection of crops during storage, as well as during transportation. However, these are highly toxic substances. Their detrimental effects may range from nausea and headache to renal failure and death. It is, therefore, pertinent to ensure their circumspect handling to avoid poisoning episodes. Its poisoning has a high mortality and recent years have seen an increase in the number of poisoning cases and deaths caused by suicidal ingestion. Yet due to their broad spectrum applications, these chemicals cannot be written off. The present communication reviews the various aspects of toxicity associated with metal phosphides.

    Full Text Available Abstract Background Childhood injury is the leading cause of mortality, morbidity and permanent disability in children in the developed world. This research examines relationships between socio-economic status (SES, demographics, and types of childhood injury in the province of Alberta, Canada. Methods Secondary analysis was performed using administrative health care data provided by Alberta Health and Wellness on all children, aged 0 to 17 years, who had injuries treated by a physician, either in a physician's office, outpatient department, emergency room and/or as a hospital inpatient, between April 1st. 1995 to March 31st. 1996. Thirteen types of childhood injury were assessed with respect to age, gender and urban/rural location using ICD9 codes, and were related to SES as determined by an individual level SES indicator, the payment status of the Alberta provincial health insurance plan. The relationships between gender, SES, rural/urban status and injury type were determined using logistic regression. Results Twenty-four percent of Alberta children had an injury treated by physician during the one year period. Peak injury rates occurred about ages 2 and 13–17 years. All injury types except poisoning were more common in males. Injuries were more frequent in urban Alberta and in urban children with lower SES (receiving health care premium assistance. Among the four most common types of injury (78.6% of the total, superficial wounds and open wounds were more common among children with lower SES, while fractures and dislocations/sprains/strains were more common among children receiving no premium assistance. Conclusion These results show that childhood injury in Alberta is a major health concern especially among males, children living in urban centres, and those living on welfare or have Treaty status. Most types of injury were more frequent in children of lower SES. Analysis of the three types of the healthcare premium subsidy allowed a more

  2. Organophosphorus and carbamate insecticide poisoning.

    Vale, Allister; Lotti, Marcello

    2015-01-01

    Both organophosphorus (OP) and carbamate insecticides inhibit acetylcholinesterase (AChE), which results in accumulation of acetylcholine (ACh) at autonomic and some central synapses and at autonomic postganglionic and neuromuscular junctions. As a consequence, ACh binds to, and stimulates, muscarinic and nicotinic receptors, thereby producing characteristic features. With OP insecticides (but not carbamates), "aging" may also occur by partial dealkylation of the serine group at the active site of AChE; recovery of AChE activity requires synthesis of new enzyme in the liver. Relapse after apparent resolution of cholinergic symptoms has been reported with OP insecticides and is termed the intermediate syndrome. This involves the onset of muscle paralysis affecting particularly upper-limb muscles, neck flexors, and cranial nerves some 24-96 hours after OP exposure and is often associated with the development of respiratory failure. OP-induced delayed neuropathy results from phosphorylation and subsequent aging of at least 70% of neuropathy target esterase. Cramping muscle pain in the lower limbs, distal numbness, and paresthesiae are followed by progressive weakness, depression of deep tendon reflexes in the lower limbs and, in severe cases, in the upper limbs. The therapeutic combination of oxime, atropine, and diazepam is well established experimentally in the treatment of OP pesticide poisoning. However, there has been controversy as to whether oximes improve morbidity and mortality in human poisoning. The explanation may be that the solvents in many formulations are primarily responsible for the high morbidity and mortality; oximes would not be expected to reduce toxicity in these circumstances. even if given in appropriate dose.

    Medulloblastoma accounts for 15-20% of childhood nervous system tumours. The risk of dying was reduced by 30% in the last twenty years. Patients are divided in risk strata according to post-surgical disease, dissemination, histology and some molecular features such as WNT subgroup and MYC status. Sixty to 70% of patients older than 3 years are assigned to the average-risk group. High-risk patients include those with disseminated and/or residual disease, large cell and/or anaplastic histotypes, MYC genes amplification. Current and currently planned clinical trials will: (1) evaluate the feasibility of reducing both the dose of craniospinal irradiation and the volume of the posterior fossa radiotherapy (RT) for those patients at low biologic risk, commonly identified as those having a medulloblastoma of the WNT subgroup; (2) determine whether intensification of chemotherapy (CT) or irradiation can improve outcome in patients with high-risk disease; (3) find target therapies allowing tailored therapies especially for relapsing patients and those with higher biological risk.

    The risks associated with exposure to inorganic lead and the means by which these risks can be minimized are outlined. Lead is used to make a variety of metal products, the grids and oxides in storage batteries, pigments, chemicals, and also for lead plating. In the United States about 70% of the total lead consumption is related to transportation. Uptake of inorganic lead is by ingestion and inhalation. About 90% of the total body burden of lead is contained within the skeletal tissues. Lead is excreted in the kidney, in sweat, and in milk. Toxic effects are directed against the blood, the nervous system, and the kidney. Symptoms of lead poisoning are abdominal pain, constipation, vomiting, asthenia, paresthesia, psychological symptoms, and diarrhea. Physical and biological monitoring can serve to protect workers. Diagnosis of lead poisoning is not easy. Treatment involves removal from exposure and/or treatment with a chelating agent.

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

    The aim of this study was to assess childhood lead exposure in a representative sample of Cairo, and to investigate the possible risk factors and sources of exposure. This cross-sectional study was conducted from November 2014 through April 2015. The target population was children aged 6 to 18 years, recruited into 4 groups, garbage city, moderate-living standard area, urban and suburban schools, and workshops in the city of Cairo. Blood lead levels (BLLs) and hemoglobin (Hb) concentrations were measured. Also, potential local environmental sources were assessed for hazardous lead contamination. Analysis on 400 participants has been carried out. A total of 113 children had BLLs in the range 10 to 20 μg/dL. Smoking fathers, housing conditions, playing outdoors, and exposure to lead in residential areas were significantly correlated with high BLLs. The mean values of hemoglobin were inversely correlated with BLLs. Children involved in pottery workshops had the highest BLLs and the lowest Hb values with a mean of (43.3 μg/dL and 8.6 g/dL, respectively). The mean value of environmental lead in workshop areas exceeded the recommended levels. Also, those values measured in dust and paint samples of garbage city were significantly high. Moreover, the mean lead levels in the soil samples were significantly higher in urban schools (P = 0.03) than the suburban ones. Childhood lead poisoning accounts for a substantial burden in Egypt, which could be preventable. Development of national prevention programs including universal screening program should be designed to reduce incidence of lead toxicity among children. PMID:26945415

    Full Text Available Sexual abuse is defined as use of child or adolescent by the adults for satisfying of sexual urges and needs with forcing, threatening or tricking. Sexual abuse can be in the form of sexual abuse without touch, sexual touch, interfemoral intercourse, sexual penetration, and sexual exploitation. The prevalence of sexual abuse is reported as 10-40%. It is seen in female four times more than in males. Abusers are frequently male, only 5-15% of them are female. The abuse by females is usually towards male child. Thirty-fifty percent of abuse cases among child and adolescent are outside the family including strangers or familiar person. Some features of abusers are introvert personality, pedophilic and antisocial personality. Most of the abusers have a history of sexual abuse or aggression during childhood. Sexual intercourse between two people who are not allowed to marry by law is called as incest. Family pattern of incest is defined globally as disorganized and dysfunctional. The most commonly reported familial pattern is rigid and patriarchal family pattern with a harsh father using force quite frequently. The clinical features and impacts of the sexual abuse on the child varies according to the relation between abusers and the child, form of abuse, duration of abuse, presence of physical assault, developmental phase, child age and psychological development before the abuse. Sexual abuse history may result in psychiatric disorders including anxiety, depression, substance dependence, suicide act, borderline personality disorder, posttraumatic stress disorder. Abuse negatively affects interpersonal relationships and self esteem of abused individuals. Several studies reported close association between risky sexual behaviors in adulthood and a history of of sexual abuse during childhood. Four traumatic dynamics including traumatic sexuality with abuse, feeling of betrayal, weakness, and stigmatization exist in childhood abuse. Trauma can cause

    Full Text Available Poison control centers hold great potential for saving health care resources particularly by preventing unnecessary medical utilization. We developed a four-question survey with three poisoning-related scenarios, based on common calls to our poison center, and one question regarding after-hours calls. We identified primary care provider offices in our poison center's region from an internet search. We contacted these offices via telephone and asked to speak to an office manager or someone responsible for triaging patient phone queries. Using a scripted form, trained investigators questioned 100 consecutive primary care provider offices on how they would handle these poisoning-related calls if there was no poison center to refer their patients to. Results of our survey suggest that 82.5% of poisoning-related calls to primary care offices would be referred to 911 or an emergency department if there was no poison center. These results further support the role that poison centers play in patient care and health care utilization.

    Full Text Available Background: Chemical exposure is a major health problem globally. Poison control centers (PCCs play a leading role both in developed and developing countries in the prevention and control of poisonous chemical exposures. In this study, we aimed to assess the current state of PCCs in Pakistan and highlight capacity building needs in these centers. Methods: A cross-sectional survey of the two registered PCCs was done during August – December 2011. Necessary services of the PCCs were evaluated and the data were recorded on a predesigned checklist. Results: Both PCCs are affiliated to a tertiary care hospital. Clinical services to poisoned patients were available 24 hours a day / 7 days a week. Information on common local products was available to poison center staff. Both centers were involved in undergraduate and post graduate teaching. Telephone poison information service was not available in either of centers. There was a limited capacity for qualitative and analytical toxicology. Common antidotes were available. There were limited surveillance activities to capture toxic risks existing in the community and also a deficiency was observed in chemical disaster planning. Conclusion: PCCs in Pakistan need capacity building for specialized training in toxicology, toxicovigilance, chemical disaster planning, analytical laboratory tests and telephone service for consultation in poisoning cases.   How to cite this article: Khan NU, Mir MU, Khan UR, Khan AR, Ara J, Raja K, et al.

  6. Adverse health effects of lead exposure on children and exploration to internal lead indicator

    International Nuclear Information System (INIS)

    Our research on adverse effects of lead exposures on physical and neurobehavioral health of children aged 6-12 years in 4 villages, labeled as K, M, L, and X, in rural China, was reported in this article. Lead in blood (PbB), urine (PbU), hairs (PbH), and nails (PbN) were measured by graphite furnace atomic absorption spectrometry. Abbreviated Symptom Questionnaire of Conner's instruments and Revised Raven's Standard Progressive Matrices were applied to evaluate childhood attention deficit/hyperactivity disorders (ADHD) and intelligences. Geometric means (SD) of PbB, PbU, PbH and PbN concentrations were 71.2 μg/L (1.56), 11.7 μg/g (1.75), 12.5 μg/g (2.82), and 25.3 μg/g (2.79), respectively. 54 (17.0%) children had PbB levels of ≥ 100 μg/L. Boys, the 6-10 years old, and living in village K were 2.11, 2.48, and 9.16 times, respectively, more likely to be poisoned by lead than girls, aged 11-12 years, and residing in X. 18 (5.7%) and 37 (11.7%) subjects had ADHD and mental retardations, respectively. Inverse relationships between intelligences and natural log transformed PbU and PbH levels were observed with respective odds ratios (95%CI) of 1.79 (1.00-3.22) and 1.46 (1.06-2.03) or 1.28 (1.04-1.58) and 1.73 (1.18-2.52) by binary or ordinal logistic regression modeling. ADHD prevalence was different by gender and age of subjects. PbU, PbH, and PbN related to PbB positively with respective correlation coefficients of 0.530, 0.477, and 0.181. Receiver operating characteristic (ROC) curves of the three measurements reveled areas under curves (AUCs) being 0.829, 0.758, and 0.687, respectively. In conclusion, children had moderate levels of lead exposures in this rural area. Intelligence declines were associated with internal lead levels among children. ROC analysis suggests PbU an internal lead indicator close to PbB.

    Our research on adverse effects of lead exposures on physical and neurobehavioral health of children aged 6-12 years in 4 villages, labeled as K, M, L, and X, in rural China, was reported in this article. Lead in blood (PbB), urine (PbU), hairs (PbH), and nails (PbN) were measured by graphite furnace atomic absorption spectrometry. Abbreviated Symptom Questionnaire of Conner's instruments and Revised Raven's Standard Progressive Matrices were applied to evaluate childhood attention deficit/hyperactivity disorders (ADHD) and intelligences. Geometric means (SD) of PbB, PbU, PbH and PbN concentrations were 71.2 {mu}g/L (1.56), 11.7 {mu}g/g (1.75), 12.5 {mu}g/g (2.82), and 25.3 {mu}g/g (2.79), respectively. 54 (17.0%) children had PbB levels of {>=} 100 {mu}g/L. Boys, the 6-10 years old, and living in village K were 2.11, 2.48, and 9.16 times, respectively, more likely to be poisoned by lead than girls, aged 11-12 years, and residing in X. 18 (5.7%) and 37 (11.7%) subjects had ADHD and mental retardations, respectively. Inverse relationships between intelligences and natural log transformed PbU and PbH levels were observed with respective odds ratios (95%CI) of 1.79 (1.00-3.22) and 1.46 (1.06-2.03) or 1.28 (1.04-1.58) and 1.73 (1.18-2.52) by binary or ordinal logistic regression modeling. ADHD prevalence was different by gender and age of subjects. PbU, PbH, and PbN related to PbB positively with respective correlation coefficients of 0.530, 0.477, and 0.181. Receiver operating characteristic (ROC) curves of the three measurements reveled areas under curves (AUCs) being 0.829, 0.758, and 0.687, respectively. In conclusion, children had moderate levels of lead exposures in this rural area. Intelligence declines were associated with internal lead levels among children. ROC analysis suggests PbU an internal lead indicator close to PbB.

  8. Childhood proptosis

    International Nuclear Information System (INIS)

    Proptosis in children is a hallmark of orbital diseases which can present a diagnostic challenge requiring thoughtful investigation. The aim of this review is to provide the reader an overview of the subject of childhood proptosis with an emphasis on the systematic and practical approach for the work-up of proptosis in children. Use of proper imaging studies is essential for the correct diagnosis. Computed tomography is a good screening test for any space occupying lesion of the orbit. Proptosis describes eye prominence due to space occupying orbital lesions. Congenital lesions usually present in the first decade of life. Acquired orbital lesions such as lymphangiomas, orbital varix, rhabdomyosarcoma and neural tumors may present at the end of the first decade of life. Metastatic tumors to the orbit, adenocarcinoma of lacrimal gland and rapidly growing masses may present with proptosis associated with pain. Visual loss can be the presenting symptoms in the patients with optic nerve (ON) gliomas, orbital meningiomas and posteriorly located tumors. Cystic lesions of the orbit may be congenital or acquired, dermoid cysts being the most common congenital orbital lesions. Some of the vascular lesions of the orbit include capillary hemangiomas, lymphangiomas, orbital varix, and arteriovenous malformations. Inflammatory process of the orbit in children include cellulitis and pseudotumor. Neural tumors such as neurofibromas, ON gilomas and meningiomas are less common causes of proptosis in children. Rhabdomyosarcoma is the most common primary orbital malignancy in children which can present with acute proptosis and is one of the few life-threatening diseases seen initially by an ophthalmologist. Secondary orbital tumors invade the orbit from adjacent sinuses, cranium or extended from the eye itself. The most common distant metastases in children include neuroblastoma and Ewing's sarcoma. Although many orbital processes can be diagnosed based on history, clinical

    Full Text Available Aluminum phosphide (ALP poisoning is one of the major causes of suicidal deaths. Toxicity by ALP is caused by the liberation of phosphine gas, which rapidly causes cell hypoxia due to inhibition of oxidative phosphorylation, leading to circulatory failure. Treatment of ALP toxicity is mainly supportive as there is no specific antidote. We recently managed 7 cases of ALP poisoning with severe hemodynamic effects. Patients were treated with supportive measures including gastric lavage with diluted potassium permanganate, coconut oil and sodium-bicarbonate first person account should be avoided in a scientific paper. Intravenous magnesium sulfate, proper hemodynamic monitoring and vasopressors. Four out of 7 survived thus suggesting a role of such supportive measures in the absence of specific antidote for ALP poisoning.

    Full Text Available Abstract Background and objective: Snake bite is a public health problem in tropical and subtropical countries. Snake problem is not only lead to poisoning but also because of the snake's mouth pathogens may be caused infection in the victims. This study was conducted to identify mouth bacteria in poisonous and non-poisonous snakes. Materials and methods: 11 non-toxic and poisonous snakes were examined before and three weeks after eating food in two stages. Bacterial samples from the oral cavity with a sterile swab were cultured on of blood agar and Mac Kanky medium. Gram staining was performed on all colonies. appropriate test methods were used for identification of gram-negative and positive bacteria. Results: Coagulase-negative Staphylococcus was the most common bacteria by 34.5 and Pseudomonas was less by 3.1 percent. Then the order, Salmonella (18.8%, Escherichia coli, Providencia (each 12.5%, Proteus, Enterococcus, Bacillus (each 6.2% were identified in the snakes. Conclusion: Our results indicate that oral cavity is contaminated to the bacteria in non-toxic and poisonous snakes. Thus, probable infection should be considered in addition to toxicity in victims.

    A 33-year-old man was admitted 8 hours after voluntary ingestion of 1875 mg of chlorophacinone (C'Operat 750 mL). The examination revealed excitation and nausea, with a normal prothrombin index (PI). Comprehensive testing for abused and therapeutic drugs in blood confirmed chlorophacinone (maximum plasma level: 27.6 mg/L), an antivitamin K (AVK) rodenticide. In a search for easy toxicological management of chlorophacinone poisoning treated by phytomenadione and a cytochrome P450 inducer (phenobarbital), PI and chlorophacinone plasma levels were monitored concomitantly during 17 days. A simple HPLC procedure for the determination of chlorophacinone in human plasma is reported for that purpose. Under phenobarbital 200 mg/day, chlorophacinone exhibited an apparent elimination half-life (3.27 days) shorter than in previously reported cases. If PI is useful for planning phytomenadione treatment and used for therapeutic monitoring of AVK, the chlorophacinone concentrations follow-up may provide a better estimation of the duration of hospitalisation. Chlorophacinone accumulation in target cells or existence of an unidentified metabolite may explain persistence of the hypocoagulability syndrome at low plasmatic concentrations of chlorophacinone. This case illustrates how toxicological management may facilitate toxicokinetics and therapeutic data acquisition.

    Our environment hosts a vast diversity of venomous and poisonous animals and plants. Clinical toxinology is devoted to understanding, preventing and treating their effects in humans and domestic animals. In Sri Lanka, yellow oleander (Thevetia peruviana, Sinhala 'kaneru'), a widespread and accessible ornamental shrub, is a popular means of self-harm. Its toxic glycosides resemble those of foxglove, against which therapeutic antibodies have been raised. A randomised placebo-controlled trial proved that this treatment effectively reversed kaneru cardiotoxicity. There are strong scientific grounds for the use of activated charcoal, but encouraging results with multiple-dose activated charcoal were not confirmed by a recent more powerful study. Venom of Russell's viper (Daboia siamensis) in Burma (Myanmar) produces lethal effects in human victims. The case of a 17-year-old rice farmer is described with pathophysiological interpretations. During the first 9 days of hospital admission he suffered episodes of shock, coagulopathy, bleeding, acute renal failure, local tissue necrosis, generally increased capillary permeability and acute symptomatic hypoglycaemia with evidence of acute pituitary/adrenal insufficiency. Antivenom rapidly restored haemostatic function but failed to correct other effects of venom toxins incurred during the 3h before he could be treated.

  14. ARE THE SO-CALLED POISONOUS FOOD-COMBINATIONS REALLY POISONOUS?

    @@ The idea that to eat certain two foods simultaneously is to get poisoned has been entertained by柄Chinese people for many years. There are about 184 pairs of the so-called poisonous food-combinations, and 180 of them are mentioned in Chinese Ancient Materia Medica, Ben-Tsao-Gung-Mu (本草纲目) or other books. (1a,2a) This belief was based upon some personal sketch, old-fashioned doctors' notes, stories and other false facts. Although these statements were originated without any experimental ground, yet many of the Chinese, even at present time, still believe them firmly. Whenever any poisoning outbreak occurs accidentally after having taken the so-called poisonous food-combination, they always attribute the cause of the poisoning to the two foods served simultaneously.

    Lead is a health hazard to most animals, causing adverse effects to the nervous and reproductive systems if in sufficient quantity. Found in most fishing jigs and sinkers, as well as some ammunition used in hunting, this metal can poison wildlife such as eagles. Eagles are raptors, or predatory birds, and their lead exposure would most likely comes from their food -- a fish which has swallowed a sinker or lead shot in carrion (dead animal matter). As part of an ongoing project to investigate the environment lead levels in Utah, the bone lead levels in the wing bones of eagles have been measured for eagle carcasses found throughout Utah. The noninvasive technique of x-ray fluorescence was used, consisting of a Cd-109 radioactive source to activate lead atoms and a HPGe detector with digital electronics to collect the gamma spectra. Preliminary results for the eagles measured to date will be presented.

    In this study nine cases of thallium poisoning in a series of homicidal poisoning were analyzed in order to provide more information concerning thallium poisoning. It was found that the most common clinical feature of thallium poisoning was peripheral neuropathy and paraesthesia was more common than amyasthenia. Understanding of these clinical characteristics of thallium poisoning was helpful to early identification and differential diagnosis. Since the early administration of Prussian Blue, as a specific antidote for thallium poisoning, can substantially improve the prognosis, it is of great importance to establish a correct and early diagnosis.

    Childhood poverty is linked to a host of physical and psychological disorders during childhood and later in life. In the study reported here, we showed that the proportion of childhood spent in poverty from birth to age 9 was linked to elevated allostatic load, a marker of chronic physiological stress, in 17-year-olds. Furthermore, this prospective longitudinal relationship was mediated by cumulative risk exposure at age 13. The greater the duration of early life spent in poverty, the greater the exposure to cumulative risk. This, in turn, leads to elevated allostatic load. Multiple psychological, biological, and neurological pathways likely account for the social patterning of psychological and physical disease.

    The purpose of this study is to assess the nature and magnitude of the deleterious health effects of subclinical over-exposure to lead in children. The study stems from concerns about the impact on the health of children in city slums who ingest leaded paint without overt evidence of poisoning and the health implication of rising levels of lead in the environment from automotive emissions. The study sample was derived mainly from a registry of children on whom blood lead determinations had been made by the New York City Department of Health and was supplemented by siblings of the registry cases and children from a lead belt area who had extractions of deciduous teeth in dental clinics. Information was obtained through parental interview, medical records, and psychometric evaluation. The data show that deleterious health effects occur in children who were treated for severe lead poisoning and in children without diagnosed lead poisoning who had elevated blood leads (≥0.06 mg-%). In the absence of diagnosed lead poisoning or elevated blood leads, excess lead exposure, measured in terms of high levels of lead in teeth, was not associated with deleterious health effects.
