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.

Botulism is a neuroparalytic illness caused by botulinum toxin, a product of the Clostridium botulinum bacteria and characteristically presents as an acute, symmetrical, descending flaccid paralysis. Albeit it is the most poisonous substance known, which even poses a major threat as biological weapons, purified and highly diluted botulinum toxin can be used to treat a wide variety of conditions associated with muscular hyperactivity, glandular hypersecretions and pain. There are six clinical presentations associated with current occurring botulism, each results from absorption of botulinum toxin into the bloodstream. ⋯ Early diagnosis and management rely on history and physical examination. Delay in treatment may allow progression of paralysis, protracted hospitalization and deaths of long-term mechanical ventilation and intensive care unit care. The clinicians must take this disease into consideration of a possible outbreak. Awaiting laboratory confirmation is an egregious error, while awareness of the clinical sign and symptoms of botulism is critical for early diagnosis. Rapid management and followed public health surveillance may greatly alleviate disease severity and decrease mortality rates.

Case ReportsLife-threatening hyponatremia after krait bite envenoming - a new syndrome.
Bites by kraits are a major cause of snake bite death in South Asia, mainly because of their venom is paralytic causing respiratory failure. We describe another life-threatening effect of the venom of some Bungarus species. ⋯ Hyponatremia is a potential serious complication in patients envenomed by B. multicinctus or B. candidus, and appropriate monitoring and management is necessary.
