SUMMARY: This is a 61-year-old white female who has been doing fairly well recently until the onset of an upper respiratory infection with a cough, recurrent chills, sweats, fever. She tried to work, was unable to. Her temperature went to 102. Chest X-ray showed a pneumonia, and it was felt that she should be admitted for further evaluation and treatment. The chest X-ray revealed a small area of infiltrate in the lingual of the left side compatible with an acute pneumonia; a follow-up study is suggested. Repeat chest X-ray showed bilateral pneumonia, clearing; however, there was a remaining area of consolidation in the lateral portion of the middle lobe. Her urine showed a specific gravity of 1.015, albumin and sugar were negative, white blood cells rare, red blood cells 0-6. White count 15,000. Hemoglobin 11.8, hematocrit 34.8, segmented cells 52, lymphocytes 18, monocytes 12, eosinophils 3, and 5 band cells. Complete blood count was normal. Sodium 137, potassium 3.4, carbon dioxide 27, chloride 97, alkaline phosphatase 10.4, blood sugar 81, cholesterol 138, creatinine 0.4, calcium 8.3, phosphorus 2.2, bilirubin 1.2, total protein 6.1, albumin 3.2, uric acid 0.5. Sputum culture grew out a 1+ enterobacter. Cardiogram was reported as showing sinus tachycardia; this later slowed down clinically. She was started on amoxicillin 500 milligrams, twice a day, and intermittent positive pressure breathing. She was continued on her home medications of Lanoxin 0.125 per day, potassium once per day, and Lasix 20 milligrams per day while in the hospital. Now her temperature has been normal for 48 hours.
