ReviewDelayed neurological sequelae from ethylene glycol, diethylene glycol and methanol poisonings.
Ethylene glycol, diethylene glycol and methanol are widely available chemicals and are found in a variety of common household products including antifreeze, windshield washer fluid, brake fluid and lubricants. Following ingestion of these glycols and methanol, patients frequently develop an early neurological syndrome consisting of inebriation, ataxia, and if severe, seizures and coma. Though uncommon, a neurological syndrome may also develop as a delayed complication. ⋯ Uncommonly, delayed neurological syndromes may develop as complications of poisoning due to ethylene glycol, diethylene glycol and methanol; the onset of such neurological damage is often days or even weeks post-ingestion. Further research is required to explain why the facial nerve is the cranial nerve most commonly involved and why the basal ganglia are predisposed to injury.

Usefulness of the serum lactate concentration for predicting mortality in acute beta-blocker poisoning.
Serum lactate measured in the emergency department was recently assessed as an excellent prognosticator of drug-overdose fatality, with the optimal lactate cutoff point being 3.0 mmol/L. However, lactate's role has never been specifically studied in beta-blocker poisonings. ⋯ Serum lactate elevation in beta-blocker poisoning is relatively mild on admission despite the presence of significant cardiovascular symptoms. Even if raised in severe poisonings and alone correlate well with prognosis, lactate concentration is not an absolute predictor of beta-blocker-overdose fatality.

2009 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 27th Annual Report.
This is the 27th Annual Report of the American Association of Poison Control Centers' (AAPCC) National Poison Data System (NPDS). As of 1 July 2009, 60 of the nation's 60 US poison centers (PCs) uploaded case data automatically. The upload time was 19.9 [9.7, 58.7] (median [25%, 75%]) minutes, creating a near real-time national exposure and information database and surveillance system. ⋯ Unintentional and intentional exposures continue to be a significant cause of morbidity and mortality in the US. The near real-time, always current status of NPDS represents a national public health resource to collect and monitor US exposure cases and information calls. The continuing mission of NPDS is to provide a nationwide infrastructure for public health surveillance for all types of exposures, public health event identification, resilience response and situational awareness tracking. NPDS is a model system for the nation and global public health.
