Tracheobronchopathia osteochondroplastica. A clinical bronchoscopic and spirometric study.

Tracheobronchopathia osteochondroplastica (TO) is a rare disease, although it probably occurs more frequently than expected. During an eight-year period, nine patients with TO were found among 2,180 performed bronchoscopies. There were four women and five men, with a mean age of 60 years. Cough, expectoration, dyspnea, hemoptysis, and recurrent airway infections were common, and most of the patients had had symptoms for more than ten years. Bronchoscopy revealed multiple yellow-white, hard, papilla-like formations reaching from the trachea to the segmental bronchi. Microscopy of biopsy specimens from the macroscopically altered mucosa showed osteocartilaginous tissue typical for TO in all patients. In eight of the patients spirometry showed an obstructive pattern.

Serum group I pepsinogens during pregnancy.

Serum group I pepsinogens (PG I) values were determined by a radioimmunoassay method in blood drawn from women at different times during pregnancy, at delivery, and 4 days after delivery. They were divided into five groups according to sampling time: group I, 0-14 weeks of pregnancy; group II, 15-27 weeks; group III, 28-40 weeks; group IV, at delivery; and group V, 4 days after delivery. No significant difference between the mean serum PG I in the various groups was found, and the mean PG I value in each group was of the same magnitude as previously found in non-pregnant controls. Since serum PG I has been reported to be positively correlated with gastric acid and pepsin secretion, this study suggests that other factors are involved in the apparently reduced occurrence of peptic ulcer during pregnancy.
