BACKGROUND: The main stay of treatment in organophophosphorous [OP] poisoning is with atropine, oximes and supportive therapy. Despite the therapy, no improvement in mortality and morbidity. Fresh frozen plasma [FFP] a source of serum cholinesterase act as bio-scavenger to neutralise organophosphate toxins to improve the patients out come. METHODS: The prospective study was conducted in 80 patients with acute OP poisoning. Patients with moderate to severe grade of OP poisoning with serum cholinesterase level <1000 IU/L were included in the study...

Organophosphate poisoning has significant gastrointestinal manifestations including vomiting, diarrhea, cramps and increased salivation. We report an uncommon gastrointestinal complication of multiple small intestinal perforations following organophosphorus poisoning. A 28-year old male presented after ingesting dichlorvos mixed with alcohol. Following the initial cholinergic symptoms, the patient developed severe shock with fever, attributed to aspiration pneumonia. Despite appropriate antibiotics, shock was persistent...

Vulture (Accipitridae) poisonings are a concern in South Africa, with hundreds of birds dying annually. Although some of these poisonings are accidental, there has been an increase in the number of intentional baiting of poached rhinoceros (Rhinocerotidae) and elephant (Elephantidae) carcasses to kill vultures that alert officials to poaching sites by circling overhead. The primary chemicals implicated are the organophosphorous and carbamate compounds. Although most poisoning events can be identified by dead vultures surrounding the scavenged carcass, weak birds are occasionally found and brought to rehabilitation centers for treatment...

INTRODUCTION: Pediatric poisonings represent a major and preventable cause of morbidity and mortality throughout the world. Epidemiologic information about poisoning among children in many lower- and middle-income countries is scarce. This study describes the epidemiology of acute poisonings in children presenting to Ain Shams University's Poisoning Treatment Center (ASU-PTC) in Cairo and determines the causative agents and characteristics of acute poisoning in several pediatric age groups...

Wild birds are exposed to insecticides in a variety of ways, at different dose levels and via multiple routes, including ingestion of contaminated food items, and dermal, inhalation, preening, and embryonic exposure. Most poisoning by insecticides occurs as a result of misuse or accidental exposure, but intentional killing of unwanted animals also occurs. In this study, we investigated insecticides in the gastric contents of dead wild birds that were suspected to have died from insecticide poisoning based on necropsy...

We hypothesized that Tabun poisoning, as well as other organophosphorous treatment, cause specific organs' oxidative changes that have not previously been substantiated investigated. In this regard, a marker for nitrosative-oxidative stress in the main haemodynamic organs (heart and kidney) could reveal the existence of such changes. In this study, for the first time we studied the nitrosative/oxidative stress in heart and kidney after acute Tabun (Ethyl N,N- Dimethylphosphoramidocyanidate) poisoning measuring by immunohistochemistry the expression of 3-nitrotyrosine--a marker for nitrosative-oxidative stress...

BACKGROUND: Suicide is an act of intentionally causing one's own death. Number of suicidal incidences is proportional to attempted suicide cases hence if attempt cases are reduced, number of suicidal death can also be decreased and for that purpose risk factors should be identified and reduced. Therefore, this study is planned to identify risk factors among lower socioeconomic rural population of surrounding areas of Hyderabad in India. MATERIALS AND METHODS: This was a prospective study in which all the suicide attempt cases reported at Bhaskar Medical College and General Hospital were included...

CONTEXT: Increased use of organophosphate insecticides (OPI) and possibility of terror groups using stocks of nerve agents underscore the need to develop effective and safe antidotes. While intramuscular administration of antidotes like atropine sulphate (AS) has certain lacunae, intravenous route may not be always feasible in emergency field conditions. OBJECTIVE: Objective was (a) to develop a novel inhalable submicronic-AS respiratory fluid as potential antidote for OPI poisoning, (b) in-vitro and in-vivo evaluation in terms of respiratory fraction, and (c) clinical study to assess drug bioavailability in blood and atropinization pattern post-inhalation...

Many organophosphorous esters synthesized for applications in industry, agriculture, or warfare irreversibly inhibit acetylcholinesterase, and acute poisoning with these compounds causes life-threatening cholinergic overstimulation. Following classical emergency treatment with atropine, an oxime, and a benzodiazepine, surviving victims often suffer brain neurodegeneration. Currently, there is no pharmacological treatment to prevent this brain injury. Here we show that a cyclic diterpenoid, (1S,2E,4R,6R,7E,11E)-cembra-2,7,11-triene-4,6-diol (4R) ameliorates the damage caused by diisopropylfluorophosphate (DFP) in the hippocampal area CA1...

A 32-year-old male presented with a history of consuming some organophosphorous compound with suicidal intention. He was treated with atropine, pralidoxime, ventilator support. During stay patient had persistent irritability, tachycardiaand hypertension despite sedation and labetalol infusion. He developed headache, visual blurring hemiparesis and focal seizures. Magnetic resonance imaging of the brain revealed multifocal hyperintensities mainly in subcortical areas of parietal and occipital regions in T2-weighted images, with increased values of Apparent Diffusion Coefficient, suggesting posterior reversible encephalopathy syndrome (PRES)...

We investigated the ability of the engineered paraoxonase-1 variants G3C9, VII-D11, I-F11, and VII-D2 to afford protection against paraoxon intoxication. Paraoxon is the toxic metabolite of parathion, a common pesticide still in use in many developing countries. An in vitro investigation showed that VII-D11 is the most efficient variant at hydrolyzing paraoxon with a kcat/Km of 2.1 × 10(6) M(-1) min(-1) and 1.6 × 10(6) M(-1) min(-1) for the enzyme expressed via adenovirus infection of 293A cells and mice, respectively...

This is the case of a young farm worker presenting with episodes of acute organic psychosis superimposed on a state of chronic anergy and hypersomnia. It is suggested that he developed an encephalopathic illness presenting with an organic bipolar affective disorder as a result of organophosphate exposure. In proposing this aetiology, an hypothesis is developed which links clinical observations and investigative results with research findings in relation to organophosphorus compounds and neuropharmacology.

BACKGROUND: Organophosphorous (OP) poisoning is one of the most common poisonings seen in India. OP compounds act through inhibition of enzyme acetylcholinesterase and estimation of pseudocholinesterase (PCE) activity strengthens the diagnosis in clinically uncertain cases of OP poisoning. The role of pralidoxime (PAM) therapy in OP poisoning has been controversial. STUDY OBJECTIVES: This study was aimed to determine the prognostic significance of estimation of PCE activity and also to assess the role of PAM therapy in OP poisoning...

The main aim of this study was to determine the causes and epidemiological aspects of unnatural deaths in the elderly. Data were collected on 4405 male and female victims of unnatural deaths aged 50 years or more from the total number of 21,235 autopsies performed in King George's Medical University, Lucknow, India over a 5-year period, from 2008 to 2012. There were 3165 male victims and 1240 female victims. Unnatural deaths were higher in rural (64%) than in urban (37%) areas. Accidental deaths were the most common manner of unnatural deaths (59%), followed by suicidal deaths (34%) and homicidal deaths (7%)...

Organophosphorous (OP) compound poisoning is one of the most common causes for admission to the Medical Intensive Care Unit. The morbidity and mortality associated with OP poisoning is due to the action of the compound at the muscarinic, nicotinic receptors, and the central nervous system. Here is a rare case of extrapyramidal manifestations occurring in the intermediate phase of OP poisoning, use of amantidine led to subsiding of the symptoms.
