Envenomation by the North American coral snake is an uncommon entity in the United States. In most cases fang marks will be present, although they may be quite small and difficult to see. The case of a young man who demonstrated evidence of envenomation following the bite of a Texas coral snake (Micrurus fulvius tenere), despite the absence of any apparent fang marks on close examination, is reported. The problems associated with coral snake envenomation in terms of diagnosis and management are reviewed.

Since the introduction of sulfonamides in the late 1930s, coalescent mastoiditis is an uncommon complication of otitis media. Swelling, erythema, and tenderness over the mastoid area with associated anterior displacement of the auricle are classic signs and symptoms of coalescent mastoiditis with formation of a subperiosteal abscess. ⋯ Prompt otolaryngologic consultation is indicated and inpatient antibiotic therapy should be begun. Surgical treatment is also needed and may obviate further complications.

A 42-year-old woman was hospitalized with aspirin intoxication. The patient developed massive skeletal muscle damage without any evidence of muscle compression, hyperthermia, or other predisposing factors. The exact mechanism by which salicylates cause muscle damage is unknown, but the muscle damage appears to be the result of a direct toxic effect. This represents the first case of isolated salicylate-induced rhabdomyolysis.

The small quantities of 7.5% hypertonic saline (HTS) in 6% Dextran 70 (DEX 70; Travenol Laboratories, Deerfield, IL) required to produce marked improvement in tissue perfusion may make it an ideal solution for the prehospital management of hypotensive trauma patients. This study shows that the initial treatment of porcine hemorrhagic shock with 7.5% HTS/6% DEX 70 results in significantly improved hemodynamics and higher survival rates than those seen in animals treated with normal saline. These results are very encouraging and dictate the need for evaluation in human trials.
