[en] Between 1940 and 1985, 24 cases of primary carcinoma of the trachea were registered at the London Regional Cancer Centre. The most common presenting symptoms were hoarseness, haemoptysis and cough. Twenty patients had epidermoid carcinoma and four had adenoid cystic carcinoma. Because of different clinical behaviours, the two histologies were separately analyzed. Of the 20 patients with epidermoid carcinoma, 19 received radiotherapy as primary treatment and one patient did not receive radiotherapy because of advanced disease. Radiation doses ranged from 4000 to 600 cGy and most patients had megavoltage irradiation. Treatment result was disappointing. Only one patient remained disease-free at 15-month follow-up and all other patients had persistent or recurrent tracheal tumour. Medain survival for all 20 patients was 5 months (range 1 to 19 monthes). Of the four patients with adenoid cystic carcinoma, two had primary surgery and postoperative radiotherapy and two had primary radiotherapy. Two patients died of disease, at 5 months and 8 years from diagnosis. Two surviving patients had 15 months follow-up: one had persistent disease and the other was free from recurrence. In this study, radiotherapy within the range of doses given was found to be an ineffective primary treatment for tracheal carcinoma. (author). 15 refs.; 3 tabs

[en] Objective: To explore a method for isolating identifying and culturing the rat trachea-bronchia epithelial cells. Methods: The rat trachea-bronchia epithelial cells were isolated by digestion with pronase and brushing with cell brush, identified using confocul and cultured in entire F12 media with no serum. Results: With this method, cells in high purity and high viability could be obtained, and about 10⁶ cells per rat. The cells grow well in entire F12 media with no serum. Conclusion: The method is useful for isolating rate trachea-bronchia epithelial cells and the entire F12 media with no serum is effective for culturing. (authors)

[en] To evaluate the influence of goitre on anatomic features and the correlation of these changes with difficulty in intubation. Methods: A questionnaire was employed to assess 139 patients scheduled for elective surgery of euthyroid goitre to predict the potential of difficult intubation. These measurements were later correlated with the patients who eventually had difficult intubations. Neck circumference, mouth width, lip test, sternomental distance, thymomental distance, Mallampati score and laryngeal palpation were evaluated. Results: All predictors were found to be significant as single predictors but on logistic regression analysis it was found that the circumference of the neck alone, was the independent predictor for difficult intubation. Conclusion: Neck thickness in patients with goitre is a significant predictor of difficult intubation and should be used in preoperative assessment to anticipate difficult intubations. (author)

[en] To evaluate usefulness of a functional tracheobronchial phantom for interventional procedure. The functional phantom was made as a actual size with human normal anatomy used silicone and a paper clay mold. A tracheobronchial-shape clay mold was placed inside a square box and liquid silicone was poured. After the silicone was formed, the clay was removed. We measured film density and tracheobronchial angle at the human, animal and phantom respectively. The film density of trachea part were 0.76 (± 0.011) in human, 0.97 (± 0.015) in animal, 0.45 (± 0.016) in phantom. The tracheobronchial bifurcation part measured 0.51 (± 0.006) in human, 0.65 (± 0.005) in animal, 0.65 (± 0.008) in phantom. The right bronchus part measured 0.14 (± 0.008) in human, 0.59 (± 0.014) in animal and 0.04 (± 0.007) in phantom. The left bronchus were 0.54 (± 0.004) in human, 0.54 (± 0.008) in animal and 0.08 (± 0.008) in phantom. At the stent part were 0.54 (± 0.004) in human, 0.59 (± 0.011) in animal and 0.04 (± 0.007) in phantom, respectively. The tracheobronchial angle of the left bronchus site were 42.6 (± 2.07).deg. in human, 43.4 (± 2.40).deg. in animal and 35 (± 2.00).deg. in phantom, respectively. The right bronchus site were 32.8 (± 2.77).deg. in human, 34.6 (± 1.94).deg. in animal and 50.2 (± 1.30).deg. in phantom, respectively. The phantom was useful for in-vitro testing of tracheobronchial interventional procedure, since it was easy to reproduce

[en] Aberrant origins of the pulmonary artery are rare anomalies, but are being reported several times in the world literature. Among them, pulmonary artery sling is the most well known anomaly, which is the left pulmonary artery arising from the right pulmonary artery. In case of pulmonary artery sling, the left pulmonary artery causes compression of the trachea and esophagus while it courses in between. In this case, we describe a case on incidentally found aberrant origin of the upper left lobe anterior and superior lingular segmental pulmonary artery without any compressions of the esophagus or trachea. In the world literature, aberrant origins of the left pulmonary artery without pulmonary artery sling was reported at one time, but currently, this is the first case of aberrant origin of the upper left lobe anterior and superior lingular segmental pulmonary artery arising from the right pulmonary artery.

[en] The clinical signs associated with intramural tracheal obstructions in two horses and a donkey were respiratory distress and coughing, which were aggravated by exercise and excitement. The obstructions were at the level of the thoracic inlet and consisted either of flattening of the cartilage rings in the dorsoventral plane or of cartilage rings having a scroll-like conformation. They appeared to be developmental in origin and to have been present for a considerable time before the onset of clinical signs. Endoscopy and radiography were helpful in the diagnosis of the condition
