The relative accessibility to various chemical agents, including chemical warfare agents and toxic industrial compounds, places a toxicological mass casualty event, including chemical terrorism, among the major threats to homeland security. TMCE represents a medical and logistic challenge with potential hazardous exposure of first-response teams. In addition, TMCE poses substantial psychological and economical impact. We have created a simple response algorithm that provides practical guidelines for participating forces in TMCE. Emphasis is placed on the role of first responders, highlighting the importance of early recognition of the event as a TMCE, informing the command and control centers, and application of appropriate self-protection. The medical identification of the toxidrome is of utmost importance as it may dictate radically different approaches and life-saving modalities. Our proposed emergency management of TMCE values the “Scoop & Run” approach orchestrated by an organized evacuation plan rather than on-site decontamination. Finally, continuous preparedness of health systems – exemplified by periodic CBRN (Chemical, Biological, Radio-Nuclear) medical training of both first responders and hospital staff, mandatory placement of antidotal auto-injectors in all ambulances and CBRN emergency kits in the emergency departments – would considerably improve the emergency medical response to TMCE.
TMCE = toxicological mass casualty event
CBRN = chemical, biological, radio-nuclear

Background: Clinicians’ impression of adolescents' alcohol or drug involvement may underestimate substance-related pathology.
Objectives: To describe the characteristics of adolescents presenting to the pediatric emergency department due to substance abuse and to determine whether physicians can reliably identify these patients.
Methods: We conducted a prospective cohort study of all patients aged 12–18 years presenting to a pediatric emergency department between 1 January 2005 and 31 December 2006 for whom a urine drug screen or ethanol blood levels was ordered. According to departmental protocol urine drug screen and ethanol levels are taken for specific indications. Based on the history and clinical findings the pediatrician in the ED assessed on a 5-point likelihood scale the possibility that the patients’ symptoms were related to substance abuse.
Results: Of the 139 patients in the study group 40 (30%) tested positive for ethanol or drugs of abuse. The median age was 16. Compared with patients who tested negative, there were more patients with decreased level of consciousness among patients who tested positive for ethanol or drugs (5% vs. 33% respectively, P < 0.001). The median physician estimate for the likelihood of substance abuse was 5 in patients who tested positive and 2 in patients who tested negative (P < 0.001). The likelihood of a positive drug/ethanol test was not affected by age or gender.
Conclusions: Since the likelihood of substance abuse is higher in patients presenting with a low level of consciousness, physicians may accurately assess the likelihood of substance abuse in these patients

Background: Long QT syndrome is an inherited cardiac disease, associated with malignant arrhythmias and sudden cardiac death.
Objectives: To map and identify the gene responsible for LQTS in an Israeli family.
Methods: A large family was screened for LQTS after one of them was successfully resuscitated from ventricular fibrillation. The DNA was examined for suspicious loci by whole genome screening and the coding region of the LQT2 gene was sequenced.
Results: Nine family members, 6 males and 3 females, age (median and interquartile range) 26 years (13, 46), who were characterized by a unique T wave pattern were diagnosed as carrying the mutant gene. The LQTS-causing gene was mapped to chromosome 7 with the A614V mutation. All of the affected members in the family were correctly identified by electrocardiogram. Corrected QT duration was inversely associated with age in the affected family members and decreased with age.
Conclusions: Careful inspection of the ECG can correctly identify LQTS in some families. Genetic analysis is needed to confirm the diagnosis and enable the correct therapy in this disease
