Presentation of echinococcus infection as lung abscess

A 35-year-old man presented with clinical and radiological features of lung abscess. Despite broad spectrum antibiotics for 5 weeks he remained systemically unwell. Underlying Echinococcus infection was suspected when repeat radiology of his chest showed a water lily sign, and this diagnosis was confirmed at thoracotomy. Hydatid disease may present as lung abscess and cause delay in diagnosis and appropriate therapy.

Methyldopa, intravascular haemolysis and renal disease. A case report

A 74-year-old man, who was receiving methyldopa to control systemic hypertension, presented to hospital in biventricular cardiac failure. He was found to be severely anaemic and jaundiced as a result of acute intravascular haemolysis with prominent haemoglobinuria. The cardiac failure and anaemia were initially refractory to fluid restriction and diuretics, but responded to red cell transfusion. Renal failure supervened, probably on the basis of hypoperfusion as a consequence of diuresis and hypotension. The patient died suddenly, possibly from myocardial infarction. Acute intravascular destruction of red cells in association with methyldopa appears not to have been previously reported.

Airway obstruction in infectious mononucleosis. A case report

A 3 1/2-year-old child with infectious mononucleosis developed upper airway obstruction because of enlarged tonsils and adenoids; the obstruction resolved spontaneously. The spectrum and management of airway obstruction in infectious mononucleosis is described.
