Three faces of costal exostoses: case series and review of literature.

The 3 cases presented here involve 3 unusual and different complications of costal exostoses: spontaneous hemothorax, pneumothorax, and pericardial effusion. All of the cases presented with chest pain to the emergency department. Two of the cases have hereditary multiple exostoses. All but one of the patients required surgical intervention. Complications of costal exostoses are rare, but hemothorax, pneumothorax, and pericardial effusions can occur.

Natural history of incidental pulmonary nodules in children.

RATIONALE: As there are no evidence based guidelines for the diagnosis and/or management of pulmonary nodules in children, there is an over reliance on the adult based algorithms when dealing with pulmonary nodules in children. We present our experience of pediatric patients evaluated for incidentally found pulmonary nodules. METHODS: Retrospective chart review of patients diagnosed with a pulmonary nodule and evaluated at Goryeb Children's Hospital between January 2000 and December 2012. PRIMARY OUTCOME: change in the size of the pulmonary nodule between the initial and follow-up imaging. RESULTS: Thirty six patients with pulmonary nodule (21 male/15 female; Median [range] age 15 [5-20] years.) were included in the study. Chest CT was obtained for respiratory symptoms and/or abnormal chest radiograph in 19 (52%). Nine pulmonary nodules (25%) were identified on abdominal CT obtained for abdominal symptoms. A total of 46 nodules were identified in 36 patients. Nine of the pulmonary nodules (9 patients) were ≤4 mm in size, 37 of the pulmonary nodules (27 patients) were >4 mm in size. Twenty-two of the 27 (81%) patients with nodule size >4 mm had follow-up CT: 14 nodules (54%) remained unchanged in size, 5 nodules (19%) decreased in size, and 7 nodules (27%) were not detected. CONCLUSION: Our review of 36 patients with pulmonary nodules shows no obvious growth of the nodules over the study period, suggesting low risk of malignancy. Routine follow-up chest computer tomography using ACCP/Fleischner Society guidelines may not apply in children without known malignancy.

Tracheal diverticula after tracheoesophageal fistula repair: case series and review of the literature.

BACKGROUND: Tracheoesophageal fistula (TEF) is the most common congenital tracheal abnormality, frequently associated with esophageal atresia. Respiratory symptoms are associated with all types of TEF, even after surgical repair of the fistula. Gastroesophageal reflux (GER) with aspiration of gastric contents, structural instability of the airways (tracheomalacia), abnormal respiratory epithelium, abnormal esophageal motility, recurrent TEF, and esophageal stenosis contribute to postsurgical complications. METHODS: We review 7 patients between 4 and 14 years of age with a history of TEF repair and persistent or worsening respiratory symptoms despite conventional airway clearance techniques and treatment of GER. RESULTS: Bronchoscopic evaluation in all 7 patients revealed tracheomalacia and a diverticulum on the posterior wall of the trachea at the fistula repair site. CONCLUSION: We hypothesize that the diverticula impaired airway clearance and contributed to persistent respiratory symptoms. Possible mechanisms for the diverticulum contributing to poor airway clearance include facilitating the pooling of secretions and acting as a "barrier" to the lower airway clearance mechanism. The diagnosis of a diverticulum should be considered early in patients with persistent respiratory symptoms after management of GER and tracheomalacia. Early obliteration of tracheal diverticula might improve respiratory status in some patients.

Safety of daily albuterol in infants with a history of bronchospasm: a multi-center placebo controlled trial.

INTRODUCTION: Inhaled short-acting bronchodilators are recommended for the quick relief of bronchospasm symptoms in children including those less than five years of age. However, limited safety data is available in this young population. METHODS: Safety data were analyzed from a randomized, double-blind, parallel group, placebo-controlled multicenter, study evaluating albuterol HFA 90microg or 180microg versus placebo three times a day for 4 weeks using a valved holding chamber, Aerochamber Plus and facemask in children birth
