1. 1989 with a five day history of malaise, sore throat, blistering around the mouth, pleuritic pain on the left side, and a dry cough. He had also developed vomiting with central abdominal pain, followed by diarrhoea for one day. On examination he had a fever, with a temperature of 38 4°C. Examination disclosed signs of left basal consolidation, which was confirmed on chest radiography. He was tender in the umbilical area. The table shows the results of the laboratory investigations. He was treated with erythromycin and cefuroxime (owing to his sensitivity to penicillin), and his temperature settled within 24 hours. He remained periodically confused for two days with episodes of hallucinations but was well enough for discharge after one week,September
