Bombings: Injury Patterns and Care
For those of you who were on the Bombings: Injury Patterns and Care COCA Conference Call that took place on April 24, 2007 the following information is in response to the question Dr. Hunt received about methemoglobinemia.
Acute Methemoglobinemia Acute methemoglobinemia usually results from exposure to certain substances, including nitrates, nitrites, and aniline derivatives. 2,4,6-Trinitrotoluene (TNT) is used in explosives and for manufacturing dyestuffs and photographic chemicals.
TNT and other explosives produce methemoglobinemia by a direct oxidizing effect on hemoglobin. TNT is absorbed through the GI tract, the skin, and the lungs. Methemoglobinemia can cause hypotension, shock, and cardiac arrhythmias. The concentration of methemoglobin in blood can be measured and the signs and symptoms are related to the percentage of blood hemoglobin that has been oxidized.

During week 17 (April 22 – 28, 2007), influenza activity continued to decrease in the United States. Data from the U.S. World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) collaborating laboratories indicated a decrease in the percentage of specimens testing positive for influenza. The percentage of visits for ILI to sentinel providers decreased during week 17 and was below the national baseline for the sixth consecutive week. Three states reported regional influenza activity; nine states reported local influenza activity; the District of Columbia, New York City, and 30 states reported sporadic influenza activity; and eight states reported no influenza activity. The number of jurisdictions reporting widespread or regional influenza activity decreased from five for week 16 to three for week 17.
