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. Case Study 2.3: What was the specific therapy used to treat this secondary infection?
Cаse Study 1: This 19-yeаr-оld student wаs in his usual state оf health until the evening priоr to admission, when he went to bed with a headache. He told his mother that he felt feverish, and on the following morning his mother found him in bed, moaning and lethargic. He was brought to the emergency room, where he appeared toxic and drowsy, but oriented. His temperature was 40C, his heart rate was 126/min., and his blood pressure was 100/60 mm Hg. He had an impressive purpuric rash (bruise-like), not blanching, most prominent on his trunk, legs and wrists. A gram stain of the material taken from one of the patient's skin lesions showed gram-negative diplococci. His white blood cell count was 26,000/ml (high) with 25% band forms (high). The platelet count was 80,000/ml (low). Blood cultures were obtained and the patient was begun on intravenous Ceftriaxone. Blood cultures subsequently grew the organism seen on the gram stains of the lesions. Case Study 1 Question 2: What is the most likely organism causing his infection?
