A 65 year old man presented with exacerbation of the chronic bronchitis from which he had been suffering for several years. A chest X-ray revealed disatelectatic pulmonary zones. Bronchoscopy showed numerous nodules, beginning at the mid-trachea and extending into the major bronchi. Histological examination of the biopsy specimens demonstrated well-differentiated cartilaginous tissue, consistent with tracheobronchopathia osteochondroplastica.

Comparative StudyPulsed Doppler echocardiography to assess pulmonary artery hypertension in chronic obstructive pulmonary disease.
Noninvasive assessment of pulmonary artery hypertension would be of great value in patients with chronic obstructive pulmonary disease (COPD). Although continuous wave Doppler echocardiographic measurement of right atrial to right ventricular pressure gradient is the most useful method of noninvasive assessment of pulmonary artery hypertension, this technique is often limited in patients with COPD. ⋯ AT and AT/RVET were significantly shorter in COPD patients (AT 92 +/- 4.3 ms; AT/RVET 0.38 +/- 0.03) as compared with healthy volunteers (AT 132 +/- 4.5 ms; p < 0.001; AT/RVET 0.46 +/- 0.02; p < 0.005), whereas RVET, PEP and PEP/RVET were not significantly different in both groups. A significant correlation was demonstrated between AT and PAPs (r = -0.76; p < 0.001) and PAPm (r = -0.82; p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
