Case ReportsBronchoscopic airway evaluation facilitated by the laryngeal mask airway in pediatric patients.
The laryngeal mask airway (LMA) was introduced for clinical use in 1988. It represents a new concept in airway management. Its role has been described as filling the gap between tracheal intubation and the anesthesia face mask. ⋯ Since its introduction, its indications and applications in anesthesia practice have increased. Although initially used as a means of delivering anesthesia and obviating the need for holding a mask on the patient, its position directly over the laryngeal inlet makes it a useful guide during flexible bronchoscopy. We report our experience in six pediatric patients and describe an anesthetic technique for bronchoscopy using the LMA for general anesthesia with spontaneous ventilation.

Longitudinal follow-up of lung function from childhood to adolescence in prematurely born patients with neonatal chronic lung disease.
We investigated whether early lung function abnormalities in prematurely born children with a history of chronic lung disease improve in late childhood and adolescence. We performed a prospective, longitudinal evaluations of pulmonary function over an 8 year period. In seventeen patients from the age (mean +/- SD) of 8.2 +/- 1.2 years to the age of 15.1 +/- 1.6 years. ⋯ We conclude that gradual normalization of air-trapping continues well into adolescence in virtually all patients with a history of prematurity and chronic lung disease. in contrast, airflow obstruction may persist but does not get worse later in life. Although chronic airflow obstruction probably is the consequence of injury to the small airways during the neonatal period, it is present in only some of the children, and it does not appear to be directly related to the perinatal history. Finally, there is evidence that airway hyperresponsiveness may be a contributing factor to the development and/or persistence of airflow obstruction in chronic lung disease of prematurity.

Case ReportsPulmonary alveolar microlithiasis in childhood: diagnosis by transbronchial biopsy.
A 7-year-old girl of Arabic origin by consanguineous parents presented with a miliary pattern on chest x-ray. Transbronchial lung biopsy revealed a histological diagnosis of pulmonary alveolar microlithiasis, a condition rarely described in childhood. This report highlights the clinical and radiological features, documents the transbronchial lung biopsy as a useful diagnostic procedure, and suggests a possible genetic etiology with autosomal recessive inheritance.
