Spontaneous pneumomediastinum in children: clinical and natural history.

UNLABELLED

Investigation of the clinical characteristics and natural history of nine children with spontaneous pneumomediastinum (SPM) was conducted at the Tel Aviv University Sheba Medical Centre between 1984 and 1994. Most cases occurred in the setting of a valsalva-type manoeuvre, while symptoms and signs on admission were mainly chest pain, dyspnoea, neck pain, subcutaneous emphysema, and Hamman's sign. Three clinical patterns concerning longterm sequelae were identified: patients without any long-term sequelae, patients with a tendency to airway hyperreactivity and subclinical asthma, and patients in whom SPM was the presenting feature of their asthma.

CONCLUSION

Close personal follow up, including pulmonary function tests, should be designed for all children with Spontaneous pneumomediastinum.
