title: Spontaneous pneumothorax in infants: a 10-year review.
abstract: OBJECTIVE
  To document the number of infants with spontaneous pneumothorax (SP) and determine the association of any underlying pathologic processes in the lung with SP.
  
  
  METHODS
  Retrospective chart review of infants admitted with SP from January 1985, to December 1994.
  
  
  METHODS
  Patients admitted to The Children's Medical Center, Dayton, Ohio.
  
  
  METHODS
  Children aged greater than 28 days but less than 1 year with the primary admitting diagnosis of SP.
  
  
  METHODS
  The number of infants with SP and description of underlying conditions associated with SP.
  
  
  RESULTS
  Six infants were identified with the admitting diagnosis of SP. All of the patients had underlying conditions that predisposed to SP: febrile seizures, anatomic abnormalities (one with an intrathoracic cystic hygroma and one with a cystic adenomatoid malformation of the lung), bronchiolitis, and two patients with Pneumocystis carinii pneumonitis. The children with SP identified in this survey accounted for one admission per 10,000 hospitalized children and 3.4 admissions per 10,000 hospitalized infants.
  
  
  CONCLUSIONS
  SP in infancy is uncommon. The data indicate that infants who present with SP have associated conditions predisposing to the development of a pulmonary air leak.
