Because concern has been raised about the efficacy and safety of flexible fiberoptic bronchoscopy (FFB) in pediatric patients with chronic cardiopulmonary disorders, we reviewed the results of 129 flexible endoscopies performed on 47 children with a history of bronchopulmonary dysplasia (BPD) at our institution over a 44-month period. Indications for FFB; weight and age of the patient; and procedure format, including medication usage, findings, specimen results, and complications, were analyzed. Evaluation of previously diagnosed subglottic stenosis and airway abnormalities were the two most common indications (33% and 32%, respectively). Persistent or recurrent infiltrates or atelectasis, need for cultures, stridor, failure to extubate, hoarseness, and persistent wheeze were also cited. Endoscopic diagnoses included adenoidal hypertrophy, laryngomalacia, vocal cord abnormalities, interarytenoid membrane, subglottic stenosis, granulomas, tracheobronchomalacia, stenosis, obstruction, generalized inflammation/edema, polyps, tracheal bronchi, and anomalous bronchial anatomy. Cytomegalovirus, pneumococcus, nontypeable Haemophilus influenzae, Pseudomonas, or mixed gram-negative flora were isolated from some patients without tracheostomy. Minor complications (transient bradycardia, mild nasopharyngeal bleeding, and mild worsening of upper airway obstruction) occurred in 3.1% of procedures, but no severe complications occurred. Management was directly affected by procedure results in 41% of procedures. We concluded that the FFB can be a safe, useful procedure in the management of children with BPD.

A prospective study was conducted over a 3-month winter period in three general practice clinics in an urban population in southern Israel to identify the etiological agents of respiratory tract infections (RTI) in adults. RTI was defined as an acute febrile illness with cough, coryza, sore throat or hoarseness. Serum samples were taken from all patients in both the acute and convalescent phases of their illness. Tests were conducted for detection of 17 microorganisms known to cause RTI, including serological tests for 16 known pathogens. An etiological diagnosis was established in 80 (66%) of the 122 patients who participated in the study. The distribution of the etiological agents was as follows: influenza B virus in 27 (22%) patients. Chlamydia pneumoniae in 22 (18%), Legionella spp. in 15 (12%), Mycoplasma pneumoniae in 13 (11%), influenza A virus in 11 (9%), Bordetella pertussis in 9 (7%), adenovirus in 4, Epstein Barr virus in 4, Haemophilus influenzae in 3, beta-hemolytic streptococci in 3, Streptococcus pneumoniae in 2, respiratory syncytial virus in 2, parainfluenza 1 virus in 2 and parainfluenza 2 virus in 1. No patients were found to be infected with Coxiella burnetii, Moraxella catarrhalis or parainfluenza 3 virus. More than one pathogen was identified in 27 (34%) patients in whom an etiological diagnosis was established. It is concluded that RTI is caused by a broad spectrum of etiological agents, a considerable number of patients having evidence of infection with more than one pathogen. The therapeutic significance of these findings should be elucidated in further studies.

We retrospectively reviewed the cases of 23 adults and six children who had been given a presumed diagnosis of acute supraglottitis between 1987 and 1997. The most common symptoms in these patients were odynophagia, dysphagia, hoarseness, and fever. Stridor and drooling were also observed, primarily in the children. Fiberoptic laryngoscopy confirmed the presence of edema and erythema of the supraglottic structures in all patients. Blood cultures were positive for Hemophilus influenzae type b in three children and for Serratia marcescens in one adult. All other blood cultures were negative. All patients were treated with intravenous broad-spectrum antibiotics and humidified oxygen, and two-thirds received intravenous corticosteroids. Patients were monitored with pulse oximetry and serial fiberoptic laryngoscopy. Two patients required intubation; one had an epiglottic abscess, and the other had laryngeal edema so severe that vocal fold mobility could not be assessed. The length of stay in the intensive care unit ranged from 1 to 7 days (mean: 1.9). All patients recovered and were discharged free of symptoms after 2 to 11 days of overall hospitalization (mean: 4.4).
