organophosphate (op) compounds are frequently used agorchemicals for deliberate self-harm in some parts of the world resulting in high mortality and morbidity. pralidoxime (2pam) is the most widely used and trialed oxime for treatment of op poisoning. there have been variations over the results of trials using 2pam for op poisoning. 2pam therapy has led to favorable outcomes in some studies, wh...

background: it is becoming apparent that although inhibition of cholinesterase plays a key role in organophosphate (op) toxicity, other factors are also important. one of the contributing factors for severity of op poisoning is electrolyte imbalances such as hypokalemia. this study was aimed at evaluating the value of hypokalemia in association with plasma cholinesterase (pche) levels in predic...

background: phenobarbital poisoning is common in vietnam. the aim of this study was to compare the effectiveness of continuous veno-venous hemofiltration (cvvh) and hemodialysis (hd) on clinical outcomes in the treatment of severe acute phenobarbital poisoning. methods: this was a retrospective observational historically controlled study. 42 patients with severe phenobarbital poisoning were enr...

Epidemics of methanol poisoning happen across the globe. There are prognostic factors associated with morbidity or mortality from methanol poisoning. Recently we have compared retrospective observational case series of methanol-poisoned patients from Norway (1979 and 2002-2005), Estonia (2001) and Tunisia (2003/2004), and patients from two different centers in Iran (Teheran 2004-2009 and Mashha...

BACKGROUND Unintentional poisoning in young children is an important public health issue. Age pattern studies have demonstrated that children aged 1-3 years have the highest levels of poisoning risk among children aged 0-4 years, yet little research has been conducted regarding risk factors specific to this three-year age group and the methodologies employed varied greatly. The purpose of the c...

Organophosphate poisoning is characterised for the most part, by acute incidents. Management is by way of first aid (in mild poisoning) and use of atropine with or without the oximes, (in moderate to severe poisoning). Of late, it has become apparent that subchronic and chronic organophosphate poisoning are a common manifestation. This review paper summarises this triphasic nature of organophos...
