Bronchoscopy, computed tomography (CT) and surgical staging procedures are complimentary methods of investigating patients with lung cancer. CT has been shown to be of value prior to bronchoscopy in the investigation of haemoptysis and malignancy, with excellent correlation between the detection of disease within the large airways on CT and direct visualisation at bronchoscopy. The utility of CT has been further increased by the development of multislice scanners with the generation of volumetric data enabling multiplanar image acquisition. Additionally the advent of CT co-registered with positron emission tomography will play an important role in guiding the choice of surgical staging procedures The increasing use of multidisciplinary medical care requires radiologists to have a greater understanding of the abilities and limitations of both bronchoscopy and surgical staging procedures in evaluating disease demonstrated on imaging.
The yield of fiberoptic bronchoscopy (FB) in the diagnosis of pulmonary metastases has not been conveniently analyzed. With the advances in the surgery of pulmonary metastases, there is a need to evaluate the diagnostic yield and the usefulness of FB to exclude other diseases with similar radiological patterns. To determine the value of FB in the diagnosis of pulmonary metastases we have retrospectively analyzed our experience in 113 patients with proven pulmonary metastases. An endobronchial lesion was identified in 57/113 (50.4%). The most frequent tumors with endobronchial lesions were thyroid (100%), head-neck (67%) and breast carcinomas (59%). The highest diagnostic yield was obtained combining techniques of brushing, washing and biopsy (72.6%); in cases with endobronchial lesions (84.2%) and with certain histological types (head-neck 100%; breast 90.9% and colon 84.6%). The most frequent radiological findings were single or multiple nodules (77.9%). Atelectasis were associated with endobronchial lesions. In conclusion, bronchoscopy is a valuable diagnostic procedure in selected patients with metastatic lung disease.
Congenital or acquired hearing loss in infants and children has been linked with lifelong deficits in speech and language acquisition, poor academic performance, personal-social maladjustments, and emotional difficulties. Identification of hearing loss through neonatal hearing screening as well as objective hearing screening of all infants and children can prevent or reduce many of these adverse consequences. This report outlines the risk indicators for hearing loss, provides guidance for when and how to assess hearing loss, and addresses hearing referral resources for children of all ages.
