BACKGROUND Lung reduction has been demonstrated to be a promising treatment for end-stage emphysema when performed on both lungs via sternotomy. The role for a thoracoscopic approach has not yet been determined. METHODS Unilateral video-assisted thoracic surgical lung reduction was performed on 50 patients for the treatment of end-stage emphysema. There(More)
Accumulation of radioactive gallium-67 citrate was observed in the lungs of a patient with postoperative adult respiratory distress syndrome. We believe that the primary mechanism of uptake of gallium is related to interstitial inflammation and repair of pulmonary tissue, rather than to a nonspecific increased alveolocapillary permeability to gallium.
PURPOSE To determine the radiologic and clinical features of newly diagnosed pulmonary sarcoidosis in human immunodeficiency virus (HIV)-infected patients. MATERIALS AND METHODS Ten HIV-infected patients (seven women, three men; age range, 26-66 years; mean age, 37 years) with newly diagnosed sarcoidosis between 1989 and 1997 were retrospectively(More)
Carnitine transporter defect is characterized by severely reduced transport of carnitine into skeletal muscle, fibroblasts, and renal tubules. All children with dilated cardiomyopathy or hypoglycemia and coma should be evaluated for this transporter defect because it is readily amenable to therapy that results in prolonged prevention of cardiac failure.(More)
The objective of the study was to describe a safe and effective treatment option for endobronchial complications after solid organ transplantation. A retrospective analysis was performed in a tertiary-care university hospital. The use of bronchoscopic argon plasma coagulation (APC) for the treatment of endobronchial lesions was studied in five solid organ(More)
A 6 year old boy with a large atrial septal defect, partial anomalous pulmonary venous drainage and unrecognized anomalous insertion of the inferior vena cava into the left atrium had cyanosis after closure of the atrial defect. Repeat study revealed direct drainage of the inferior vena cava into the left atrium with moderate arterial oxygen desaturation.(More)
Chronic hoarseness is a rare presenting or accompanying sign of congestive heart failure in infancy. Two infants had a paralyzed left vocal cord, secondary to traction on their left recurrent laryngeal nerve. Both had significant underlying congenital heart disease (type 2 aortopulmonary window, ventricular septal defect, patent ductus arteriosus; large(More)
A 46-year-old man presented to his physician with nonspecific abdominal complaints. CT of the abdomen was obtained to investigate his symptoms, which showed significant pericardial effusion. One week after drainage of the pericardial fluid, his symptoms recurred and a transesophageal echo showed a right atrial tumor. Cardiac catheterization demonstrated(More)
