BACKGROUND: Agricultural pesticide poisoning is a major contributor to the global burden of suicide. Over the last decade there has been a marked decrease in the incidence of suicide worldwide. It is unclear whether pesticide poisoning still plays a significant role in the global incidence of suicide. METHODS: WHO method-specific suicide data were supplemented by a systematic review of the literature between 2006 and 2015, including searches of thirteen electronic databases and Google, citation searching and a review of reference lists and personal collections...

AIM: Acute kidney injury (AKI) is common following deliberate self-poisoning with a combination washing powder containing oxalic acid (H2C2O4) and potassium permanganate (KMnO4). Early and rapid increases in serum creatinine (sCr) follow severe poisoning. We investigated the relationship of these increases with direct nephrotoxicity in an ongoing multicenter prospective cohort study in Sri Lanka exploring AKI following poisoning. METHODS: Multiple measures of change in kidney function were evaluated in 48 consenting patients who had serial sCr and serum cystatin C (sCysC) data available...

CONTEXT: Ciguatera fish poisoning arises primarily from consumption of carnivorous reef fish caught in tropical and sub-tropical waters. Ciguatoxins, a class of tasteless, heat-stable, polycyclic toxins produced by dinoflagellates, accumulate through the food chain and concentrate in various carnivorous fish, such as groupers, barracudas, wrasses, amberjack, kingfishes, and eels. Characteristics of ciguatera fish poisoning include early nausea, vomiting, and diarrhea in the first one to two days post ingestion, followed by the appearance of sensory disturbances...

INTRODUCTION: Cyanoacrylate (Super Glue(®)) exposures are commonly reported to poison control centers, but little has been published in the medical literature regarding these exposures. We sought to characterize cyanoacrylate exposures reported to a poison control system. METHODS: We performed a retrospective review of a poison system's database for all cases of single-substance human exposure to cyanoacrylate-containing products from 2005 to 2015. Data collected included age, gender, route of exposure, clinical effects, treatments recommended and medical outcome...

INTRODUCTION: Paraphenylene diamine (PPD) ingestion is manifesting as one of the more common ways of committing suicide in Southern Punjab, Pakistan, especially Bahawalpur. PPD is an ingredient of a compound commonly known "Kala Pathar" which means "Black Stone" in Urdu. It is readily available in the market at low cost and is used to dye hair and fur. Its intoxication inhibits cellular oxidation and affects the muscles causing rhabdomyolysis. This leads to myoglobinuria followed by renal failure and edema of face and throat resulting in respiratory difficulty...

Early haemoperfusion (HP) therapy has been found to be very effective in acute paraquat (PQ) poisoning, but the effective rescue window is still uncertain. Demographic data and the type of therapies administered of 621 patients were included as confounding factors in this retrospective study. After receiver operating characteristic curve analysis and intra-group/subgroup analysis, the initiation of glucocorticoid therapy within 3 hrs of exposure with a second treatment given <21 hrs after exposure, HP initiated within 4 hrs of exposure with a second treatment given <20 hrs after exposure, the appearance of pulmonary lesions ≤8 days after exposure and six other variables were used in a multiple analysis...

Several marine microalgae produce dangerous toxins very damaging to human health, aquatic ecosystems and coastal resources. These Harmful Algal Blooms (HABs) in recent decades seem greatly increased regarding frequency, severity and biogeographical level, causing serious health risks as a consequence of the consumption of contaminated seafood. Toxins can cause various clinically described syndromes, characterised by a wide range of symptoms: amnesic (ASP), diarrhoetic (DSP), azaspirazid (AZP), neurotoxic (NSP) and paralytic (PSP) shellfish poisonings and ciguatera fish poisoning...

Lead (Pb) as a topically poisonous metal represents a serious threat to the ecological environment and especially to human beings. Therefore, it is urgent to develop a rapid and reliable monitoring technique for this heavy metal in the environmental samples. In the present study, we have designed a selective and sensitive method for the determination of ultratrace contents of Pb(2+) in biological samples, based on the guanine (G)-quadruplex formed by the aptamer with hairpin structure and Pb(2+). For this purpose, Pb(2+) specific aptamer serving as affinity probe to capture and separate trace amounts of the analyte, was covalently linked to Fe3O4/graphene oxide (GO) surface by using a suitable cross-linking agent...

This study introduces a novel competent dendritic copper oxide-platinum nanocatalyst (nano-Cu2O-Pt) immobilized onto a glassy carbon (GC) substrate for formic acid (FA) electrooxidation (FAO); the prime reaction in the anodic compartment of direct formic acid fuel cells (DFAFCs). Interestingly, the proposed catalyst exhibited an outstanding improvement for FAO compared to the traditional platinum nanoparticles (nano-Pt) modified GC (nano-Pt/GC) catalyst. This was evaluated from steering the reaction mechanism towards the desired direct route producing carbon dioxide (CO2); consistently with mitigating the other undesired indirect pathway producing carbon monoxide (CO); the potential poison deteriorating the catalytic activity of typical Pt-based catalysts...

In this study, chitosan functionalised magnetic nano-particles (CMNP) was synthesised and utilised as an effective adsorbent for the removal of Pb(II) ions from aqueous solution. The experimental studies reveal that adsorbent material has finer adsorption capacity for the removal of heavy metal ions. Parameters affecting the adsorption of Pb(II) ions on CMNP, such as initial Pb(II) ion concentration, contact time, solution pH, adsorbent dosage and temperature were studied. The adsorption equilibrium study showed that present adsorption system followed a Freundlich isotherm model...

The emergence of methicillin-resistant Staphylococcus aureus (MRSA) in food has provoked a great concern about the presence of MRSA in associated foodstuff. Although MRSA is often detected in various retailed meat products, it seems that food handlers are more strongly associated with this type of food contamination. Thus, it can be easily postulated that any food could be contaminated with this pathogen in an industrial environment or in household and cause food poisoning. To this direction, the effect of rocket (Eruca sativa) extract on MRSA growth and proteome was examined in the present study...

Environmental health literacy (EHL) is a promising and evolving field of research that could benefit from youth engagement. Yet studies focused on youths' environmental health awareness and concerns are limited. For example, although lead exposure remains a threat to youth development in urban environments, no published studies have measured urban youth's knowledge of lead poisoning. A CBPR partnership established a youth advisory council (YAC) who helped to design, interpret and disseminate a mixed methods study exploring environmental health perceptions among urban youths ages 10-18...

Lithium has a narrow therapeutic window. Frequent monitoring of both serum levels and clinical signs of toxicity is warranted because toxicity may be present even when concentrations are within the therapeutic range. We report the case of a man with lithium poisoning, with persistent neurologic signs and symptoms even after removal of lithium from circulation - a diagnosis of syndrome of irreversible lithium-effectuated neurotoxicity (SILENT) was made.

In Paraguay, pesticides are the causative agent in 13.7% of poisonings, especially organophosphorus compounds. Such poisoning produces the inhibition of acetylcholinesterase generating three possible clinical conditions: acute poisoning, intermediate syndrome or late neurotoxicity. We present 15 cases of acute poisoning, ten women and five men from a rural community between 5 and 67 years of age, whose symptoms began after using water contaminated by pesticides from the community network. The most common symptoms were nausea and vomiting, followed by abdominal pain, headache, fever, itching, red eyes and sweating...

Increases in reported incidence of ciguatera fish poisoning (hereafter ciguatera) have been linked to warmer sea temperatures that are known to trigger coral bleaching events. The drivers that trigger blooms of ciguatera-causing dinoflagellates on the Great Barrier Reef (GBR) are poorly understood. This study investigated the effects of increased temperatures and lowered salinities, often associated with environmental disturbance events, on the population growth of two strains of the potentially ciguatera-causing dinoflagellate, Gambierdiscus carpenteri (NQAIF116 and NQAIF380)...

Since the outbreak of methylmercury (MeHg) poisoning in Japan and Iraq, mercury (Hg) is classified as well-established teratogen. The Portuguese region of Aveiro faced some decades ago an environmental Hg contamination due to activities from a chlor-alkali plant. Until now, no apparent evaluation was conducted regarding prenatal exposure to Hg in this area. The main objectives of this study were to: i) assess maternal and fetal exposure to Hg in the Aveiro region using noninvasive biological matrices; ii) examine the influence of variables that may contribute to Hg exposure during pregnancy; and iii) improve knowledge regarding metal accumulation and distribution over the maternal-fetal-placental unit...
