Cаse Study 2: This 63-yeаr-оld аlcоhоlic was taken to the emergency room of an outside hospital with obvious gangrene of both feet. He was stuporous. During that evening, he had a seizure and was treated with phenytoin and barbiturates. By the night of transfer he was noted to have opisthotonic posturing and to have developed increasing respiratory distress and unresponsiveness. On examination, he had a temperature of 41.7°C rectally, a blood pressure of 70/30 mmHg, a heart rate of 110 beats/min, and a respiratory rate of 40/min. Examination was notable for marked trismus. The neck was stiff and hyperextended. Necrotic, blackened areas were present over both feet and several draining ulcers were noted on the heels and toes. Neurologically the patient responded to deep pain with a grimace. On the basis of these findings, specific therapy, in addition to supportive care, was initiated, and the patient ultimately recovered.
