The evaluation of pleural effusions in children differ from that of the adult in cause, symptom presentation, character of the fluid, techniques for diagnosis, treatment or management, and prognosis. These similarities and differences are reviewed with emphasis on the treatment of empyema.

Infants with complications of Pierre Robin sequence are at increased risk of airway obstruction and resultant hypoxia, cor pulmonale, failure to thrive, and cerebral impairment. In an effort to minimize such complications, patients with Pierre Robin sequence were examined prospectively by a multidisciplinary team using polysomnography and continuous oximetry. Obstructive apnea and desaturation occurred in 18 of the 21 patients studied. Four children required only home apnea monitoring, and six required only monitoring and supplemental oxygen. Seven children had lip-tongue adhesion procedures performed, and four required tracheostomy. No patients died. All patients with isolated Pierre Robin sequence had normal development at follow-up except for one child who had experienced a respiratory arrest before referral. With improvements in neonatal intensive care, testing for respiratory assessment, improved surgical and postoperative intervention and home monitoring, the morbidity and mortality for children with Pierre Robin sequence can be reduced markedly.

A 13-year-old patient was referred for evaluation of pulmonary symptoms and was subsequently diagnosed to have achalasia. An esophagram revealed a dilated esophagus which obstructed the trachea at the thoracic outlet during a forced expiratory maneuver. Pulmonary function tests, obtained before and after esophagomyotomy, are presented.
