Video-Assisted Thoracoscopic Resection of Recurrent Intrapulmonary Bronchogenic Cyst after Thoracotomy

Intrapulmonary bronchogenic cysts are typically treated surgically by lobectomy to completely excise the cyst to minimize risk for recurrence. Video-assisted thoracoscopic surgery is being used with increasing frequency to manage intrathoracic pathology. We present a patient who underwent resection of a bronchogenic cyst 20 years before. She developed a symptomatic recurrence, and video-assisted thoracoscopic surgery was used to lyse adhesions from her previous posterolateral thoracotomy and perform an intraparenchymal dissection to resect the pathologic lesion while sparing the remaining parenchyma of her right upper lobe. At 2 years of follow-up, the patient is without evidence of recurrence.

Correlation of Age and Incidence of Pancreatic Exocrine Nodular Hyperplasia in the Dog

The purpose of this study was to determine the prevalence of pancreatic nodular hyperplasia (NH) and its relation to age in the dog. A total of 101 dogs were enrolled. The pancreas was evaluated by histology and hyperplastic lesions were detected and scored. Age was recorded from the medical records. Correlation of age with inflammation and presence of hyperplastic lesions was evaluated. Of the 101 dogs, 81 (80.2%) had evidence of NH. Twenty-five of the 101 dogs did not have evidence of pancreatic inflammation, necrosis, and/or fibrosis, 17 (68.0%) of which had evidence of NH. Mean ± SD age in dogs with NH was significantly higher compared with dogs without NH (9.5 ± 3.4 years versus 3.4 ± 3.3; p-value < 0.0001). We conclude that NH is a common pathologic lesion in dogs and shows a positive correlation with age regardless of the presence or absence of pancreatic inflammation, necrosis, or fibrosis.

Doubts and Water Droplets in Mist Therapy

One can have only high regard for the dedicated effort that Matthews and his group put forth to help children with cystic fibrosis. Yet with all this one cannot accept some of the thought which is embodied in this quotation from their recent paper.1 "For therapy, the nebulizer must provide a particle size which will result in deposition at the site of the pathologic lesion being treated. In disease of the trachea of larynx a nebulizer providing a very small particle-size mist is senseless, since 99% of the particles under 6µ in diameter will pass the involved area without depositing.
