Patients with cancer frequently develop pneumonitis for which no cause is documented ante mortem. Noninvasive diagnostic techniques, such as sputum induction, are generally inadequate, especially in myelosuppressed patients. To avoid pulmonary contamination with organisms colonizing the oronasopharynx and to obtain uncontaminated speciemens, 38 patients underwent bronchial brushing utilizing a ...

A 20-year-old Welsh Mountain Pony (212 kg) mare was initially presented for a chronic cough, fever, weight loss and low grade abdominal pain. She later developed dyspnoea, tachypnoea and exercise intolerance. The presence of multiple masses (up to 17 cm diameter) in the pulmonary parenchyma was established using lateral thoracic radiography and transthoracic ultrasonography. Encapsulated, buddi...

Phonation was induced in 10 mongrel dogs under general anesthesia by way of transtracheal stimulation of the recurrent laryngeal nerves under conditions of constant air flow. Although stimulation voltages were approximately 10 times the voltage required for direct stimulation, no cardiac or respiratory abnormalities were observed. Photoglottographic and electroglottographic signals were the sam...

A 39 year old woman was admitted with fever and an exacerbation of asthma. The chest radiograph showed extensive bilateral lung infiltrates, but transtracheal needle aspiration did not reveal any infectious organisms. The bronchoalveolar fluid lavage contained a large number of Trichomonas tenax and an increased percentage of eosinophils. Corticosteroids provided a dramatic response. Because of...
