Pediatric nerve agent poisoning: medical and operational considerations for emergency medical services in a large American city.

Most published recommendations for treatment of pediatric nerve agent poisoning are based on standard resuscitation doses for these agents. However, certain medical and operational concerns suggest that an alternative approach may be warranted for treatment of children by emergency medical personnel after mass chemical events. (1) There is evidence both that suprapharmacological doses may be warranted and that side effects from antidote overdosage can be tolerated. (2) There is concern that many emergency medical personnel will have difficulty determining both the age of the child and the severity of the symptoms. Therefore, the Regional Emergency Medical Advisory Committee of New York City and the Fire Department, City of New York, Bureau of Emergency Medical Services, in collaboration with the Center for Pediatric Emergency Medicine of the New York University School of Medicine and the Bellevue Hospital Center, have developed a pediatric nerve agent antidote dosing schedule that addresses these considerations. These doses are comparable to those being administered to adults with severe symptoms and within limits deemed tolerable after inadvertent nerve agent overdose in children. We conclude that the above approach is likely a safe and effective alternative to weight-based dosing of children, which will be nearly impossible to attain under field conditions.

Crush syndrome.

The assessment, management, and treatment of the entrapped victim are critical skills needed to ensure a successful outcome. Individuals have been trapped in the "rubble" for even short periods of time only to succumb to predictable consequences of muscle compression injury. The clinician should be prepared to address issues of crush syndrome (including compartment syndrome) proactively and aggressively. The history of this disease is clear and well documented both in the military literature and in the earthquake rescue reviews. The key to management is managing and predicting clinical conditions before they present themselves. The potential exists in the urban environment (with the potential of building collapses) to have patients with crush syndrome that far exceed local medical capabilities should be part of modern disaster planning. This article reviews the various body systems and presents management and assessment strategies for the clinician.

Immunization with Porphyromonas gingivalis capsular polysaccharide prevents P. gingivalis-elicited oral bone loss in a murine model.

The capsular polysaccharide (CPS) of the periodontal pathogen Porphyromonas gingivalis is an important virulence factor for this organism. We purified P. gingivalis CPS, immunized mice with this antigen, and assessed the vaccine potential of P. gingivalis CPS by using the murine oral challenge model. Animals immunized with P. gingivalis CPS developed elevated levels of immunoglobulin M (IgM) and IgG in serum that reacted with whole P. gingivalis organisms. The mice immunized with P. gingivalis CPS were protected from P. gingivalis-elicited oral bone loss. These data demonstrate that P. gingivalis CPS is a vaccine candidate for prevention of P. gingivalis-elicited oral bone loss.
