LIFE system (lung imaging fluorescence endoscope) is a new system of detection for early lung cancer using a He-Cd laser through a conventional fiberoptic bronchoscope. This system is able to capture and processing the autofluorescence from the bronchial mucosa and to show it in a video screen in real time. In the screen the normal tissue appears in green colour and the neoplastic tissue in brown colour. The first studies performed with LIFE system show the same specificity of the conventional bronchoscopy but the sensibility is 50% higher. In this paper we present the first case of detection of a occult squamous cell carcinoma with sputum and bronchial aspiration cytology positive for carcinoma but chest X ray, CT scanner and bronchoscopy negative for lung cancer. The LIFE system was able to detect carcinoma in the carina.
BACKGROUND: There is little information regarding full polysomnographic examination of infants for the evaluation of stridor or stertor. OBJECTIVE: To determine the usefulness of polysomnographic examination in the evaluation of airway disorders in infants. DESIGN: Case review series. SETTING: Tertiary pediatric care center and sleep disorders center. PATIENTS: Younger than 10 months. INTERVENTION: Full polysomnography and treatment with a positive-pressure assistive device or surgery if indicated. MAIN OUTCOME MEASURES: Electroencephalographic findings, amount and length of apnea, percentage of desaturation and carbon dioxide retention, sleep architecture, amount of hypopnea as well as sleep arousals, episodes of gastroesophageal reflux, and clinical follow-up. RESULTS: Of 60 full pediatric polysomnograms performed at our institution each year, only 17 were obtained in children younger than 10 months for determination of symptoms of stridor or stertor over the past 8 years. In several cases, interpretation of 4-channel studies led to the wrong conclusions and inadequate treatment. Diagnoses made using full polysomnography included 3 children with seizure disorders, 1 with disorganized brain activity, 2 with gastroesophageal reflux, and 7 with anatomical obstructions, 3 of whom were successfully treated with a positive-pressure assistive device and 4 of whom were treated surgically. CONCLUSIONS: Full polysomnography provides physiological data that complement anatomical data obtained via endoscopy and is a useful tool for evaluating the significance of airway disorders in infants.
BACKGROUND AND OBJECTIVE: Hemangiomas have a typical clinical course and may lead to life-threatening obstruction if the central respiratory tract is involved. STUDY DESIGN/PATIENTS AND METHODS: This was observed in 32 children over a period of 20 years. The radiation parameters and application procedure of Neodymium:Yttrium-Aluminum-Garnet-laser (Nd:YAG-laser) therapy were adjusted for the degree of obstruction and the type of disease. RESULTS: The success rate was 93.8%, of which a maximum of one application was sufficient in 24 children (75.0%). Subglottic cicatricial stenosis was considered a laser-related complication. CONCLUSION: Nd:YAG-laser treatment is a safe and effective therapeutic measure for eliminating respiratory tract obstruction caused by hemangiomas.
