acute chest syndrome
Definition: a syndrome occurring in association with sickle cell disease defined by a new infiltrate on chest radiograph; associated with one or more new symptoms: fever, cough, sputum production, dyspnea, or hypoxia. It occurs most commonly in the 2–4-year-old age group and declines in incidence with age. A past history of this finding is associated with earlier mortality compared with those patients who have never experienced an episode.
