Objectives: Rates of Deliberate Self-Poisoning (DSP) attempts are subjected to under-counting, under-reporting, and denying suicide attempts. In this study, therefore, we seek to estimate the rate of under-reported DSPs, which is the most common way of suicide attempts in Iran. Methods: Using truncated count models, we estimated rates and numbers of under-counted DSP attempts in western part of Iran in 2015. By this method, n0, namely the number of people attempted DSP, but not referring to any health care centers, was calculated through data connection...

REVIEW
Yuri B Shmukler, Denis A Nikishin
Ciguatoxins (CTX) and brevetoxins (BTX) are polycyclic ethereal compounds biosynthesized by the worldwide distributed planktonic and epibenthic dinoflagellates of Gambierdiscus and Karenia genera, correspondingly. Ciguatera, evoked by CTXs, is a type of ichthyosarcotoxism, which involves a variety of gastrointestinal and neurological symptoms, while BTXs cause so-called neurotoxic shellfish poisoning. Both types of toxins are reviewed together because of similar mechanisms of their action. These are the only molecules known to activate voltage-sensitive Na⁺-channels in mammals through a specific interaction with site 5 of its α-subunit and may compete for it, which results in an increase in neuronal excitability, neurotransmitter release and impairment of synaptic vesicle recycling...

Mr Litvinenko died on 23rd November 2006, having been poisoned with polonium-210 on 1st November, with evidence of a previous poisoning attempt during October 2006. Measurements of 210Po in urine samples were made for a large number of people to determine whether they may have been contaminated. In the majority of cases, measured levels were attributable to the presence of 210Po from normal dietary sources. For a small number of cases, elevated levels provided evidence of direct contamination associated with the poisonings...

The CuPtPd catalyst is designed and synthesized successfully via directly reducing metal ions. The composition, morphology and structure of the as-prepared CuPtPd nanohybrids are characterized by scanning electron microscope (SEM) and transmission electron microscopy (TEM), energy-dispersive spectrometer (EDS), selected-area electron diffraction (SAED), X-ray diffraction (XRD), and inductively coupled plasma atomic emission spectrometry (ICP-AES). By comparison of the electrocatalytic properties of the ternary CuPtPd catalyst with bimetallic catalysts, we find that ternary nanocomposites perform better electrocatalytic and anti-poisoning activity towards oxidation of methanol...

A catalytic antibody A17 and its mutants highly efficiently interact with organophosphorus pesticide paraoxon. In this work, we studied the protective properties of antibody A17-K47 in paraoxon poisoning using a mouse model. The optimal paraoxon dose simulating the acute toxic effect of organophosphorus compounds was 550 μg/kg. The pharmacokinetic parameters of A17-K47 antibody were t1/2distr =7.2±1.4 min, t1/2el =330±20 min. The antibody did not cause toxic effects when administered at a ten-fold calculated therapeutic dose (610 mg/kg)...

Organophosphate (OP) poisoning is a major global health issue; while compounds from this group have been used intensively over the last century, an effective antidote is still lacking. Oxime-type AChE reactivators are used to reactivate the OP inhibited AChE. Pralidoxime is the only US Food and Drug Administration, (FDA) approved oxime for therapeutic use but its efficacy has been disappointing. Two novel oximes (K378 and K727) were investigated in silico and in vitro and compared with an experimental oxime (kamiloxime; K-27) and pralidoxime...

In 2010, a series of lead poisoning outbreaks linked to artisanal gold processing killed at least 400 young children in Zamfara State in northwestern Nigeria. There were several efforts to respond to the outbreaks as they occurred. Subsequent recurrence of lead poisoning outbreaks within Zamfara and beyond suggested that there were no efforts to mitigate the outbreaks as recommended for disaster management. This case study, to be completed within 3 hours, is suitable for senior level public health officials and those training for such positions...

Hydrogen sulfide (H2 S) is a highly neurotoxic gas. It is the second most common cause of gas-induced deaths. Beyond mortality, surviving victims of acute exposure may suffer long-term neurological sequelae. There is a need to develop countermeasures against H2 S poisoning. However, no translational animal model of H2 S-induced neurological sequelae exists. Here, we describe a novel mouse model of H2 S-induced neurotoxicity for translational research. In paradigm I, C57/BL6 mice were exposed to 765 ppm H2 S for 40 min on day 1, followed by 15-min daily exposures for periods ranging from 1 to 6 days...

Amitraz is an acaricide and insecticide used to treat ticks, which infest domestic animals in developing countries. Because of its widespread use, it is one of the common poisons unintentionally consumed by infants and children when left unsupervised. A 3-year-old boy was brought with unintentional consumption of Amitraz. On examination, he was found to be progressively drowsy, with an irregular pulse, bradycardia, and hypotension. He was treated with atropine, intravenous fluids, and dopamine infusion; hemodynamic stability was achieved within 36 hours after ingestion...

An 89-year-old man attempted suicide by ingesting a pesticide (trichlorfon). After surviving the initial critical period in the intensive care unit, he developed rapidly progressive distal weakness and sensory disturbance. Electrophysiological examinations revealed sensory motor axonal polyneuropathy. Delayed polyneuropathy is a rare manifestation of organophosphate poisoning. Nerve conduction studies play an important role in the diagnosis of this rare clinical condition.

An innovative method was developed to detect fluoroacetate poisoning in cattle by headspace/gas chromatographic analysis of earwax samples of intoxicated cattle. Samples were collected from 2 groups of cattle subjected to induced fluoroacetate intoxication, each group receiving a different dose of acetamide (antidote). Monofluoroacetic acid was detected in samples of intoxicated cattle in concentrations inversely proportional to the dose of acetamide. Thus, earwax analysis represents a successful approach for detection and monitoring of fluoroacetate poisoning...
