A 67-year-old female was admitted to our hospital, because of high fever and dry cough. She had undergone semiradical hysterectomy and radiation therapy for carcinoma of the uterine cervix one year previously. Her chest roentgenograms on admission showed lobar consolidation of the left upper lobe. Antibiotics were administered but her general condition and pulmonary consolidation did not improve. As Legionellosis was highly suspected, we performed bronchoscopic examinations. Bronchial mucosa was almost normal with no secretion, and Legionella was isolated from the specimen obtained bronchoscopically. Six days later, L. pneumophila serogroup 2 was isolated and identified from an intratracheal aspiration, and serological diagnosis was made by indirect immunofluorescence antibody. We could also detect the bacteria in the BALF by immunofluorescence microscopy and in the tissue of the TBLB specimen with the ABC method.

The purpose of this study was to ascertain the immunological abnormality of hypersensitivity pneumonitis. The relationship between T cell subsets of lymphocytes in transbronchial lung biopsy (TBLB) specimens and in bronchoalveolar lavage fluid (BALF) were studied in 3 cases of farmer's lung disease (FLD). The lung specimens were examined by immunoperoxidase staining (ABC method) and the cells in BALF by the immunofluorescence method on the flowcytometry. All cases of FLD were diagnosed according to the following criteria: 1) history of exposure to FLD antigen, 2) clinical symptoms (cough, fever, breathlessness), 3) radiologic feature (diffuse small nodular pattern) and functional pattern of interstitial lung disease and 4) evidence of antibodies against Micropolyspora faeni. Histologically, granulomatous interstitial pneumonitis was revealed in all cases. Immunohistochemically, the number of positive lymphocytes was as follows: for Leu 4 (pan T cell) 8.6 cells/15.6 x 10(-3) mm2; Leu 3a (helper/inducer T cell) 5.1 cells; Leu 2a(suppressor/cytotoxic T cell) 1.2 cells on average, respectively. The Leu 3a+ cells were larger in number than the Leu 2a+ cells and the Leu 3a+/Leu 2a+ ratio was 4.76. In the BALF, the percentage of OKT3+ cells (pan T cell) was increased. The percentage of OKT4+ cells (helper/inducer T cell) was higher than that of OKT8+ cells (suppressor/cytotoxic T cell). The OKT4+/OKT8+ ratio was 6.65 in the BALF. The result of this study revealed the close relationship between the numerical distribution of T cell subsets in the lung tissue and in the BALF. It is suggested that the immuno-reaction in the lung tissue of patients with FLD is a type of helper-T cell alveolitis.

The main pharmacological activities of 2-(7'theophyllinemethyl)-1,3-dioxolane (ABC 12/3), a new theophyllinic derivative, were studied. This compound was shown to possess an extremely high anti-bronchospastic activity in vitro and in vivo, its effectiveness being much greater than that of theophylline; and it also showed a strong activity as an antitussive on experimental cough induced by citric acid or histamine aerosol. However the compound showed little activity on the intestinal smooth muscle, the cardiovascular and the central nervous systems. The acute toxicity of ABC 12/3 is rather low and therefore it should be possible to utilize it for therapeutic purposes in tracheobronchial diseases.

To illustrate a previously unreported method of tracheal stent removal that appears to cause less mucosal injury we present a case of a 9-year-old Down syndrome patient with a history of tracheoesophageal fistula, brought to our attention after recurrent bouts of exacerbating cough and tracheo-bronchitis. Endoscopic examination under general anesthesia noted the presence of severe tracheomalacia with inspiratory collapse, and a 10-mm balloon expandable metallic stent (BEMS) was deployed and symptomatic improvement was noted. The initial stent was then removed to consider a definitive procedure using the typical grasping fashion with an alligator forceps and expected mucosal excoriation was noted. Due to symptom recurrence, the patient underwent placement of a second BEMS stent. Initial improvement was noted followed by recurrent episodes of respiratory distress due to granulation tissue formation and stent compression and a decision to remove the stent was made. A new method of stent removal deemed ABC (airway balloon collapse) method was utilized where an expandable airway balloon is placed outside the stent between the stent and tracheal wall and then inflated to collapse the stent, facilitating easy removal.
