Tracheoplasty for congenital stenosis of the entire trachea.

Congenital stenosis involving the entire length of the trachea has generally been regarded as a fatal disease. Tracheoplasty using costal cartilage grafts to enlarge the lumen was successfully employed in such a case, and the technique is described. A 12-mo-old female was referred with recurrent severe respiratory distress since birth. By tracheoscopy and bronchography, the entire trachea was seen to be stenotic. The left bronchus was of normal caliber by bronchogram and the left lung was over inflated, while the right lung was aplastic. Through a midsternal thoracotomy, the left bronchus was incised and cannulated for ventilation. Longitudinal incision of the entire length of the anterior wall of the trachea permitted the advance of a nasotracheal tube along the inner surface of the divided trachea to the carina. Two pieces of costal cartilage were used to fill the defect in the anterior wall of the trachea. The grafts were attached to the tracheal edges by interrupted 5-0 Dexon sutures. The endotracheal tube was successfully removed two months later. The subsequent course of the patient has been satisfactory.

Relationship between serotype and certain biological and biochemical characteristics of strains of the Mycobacterium avium and Mycobacterium intracellulare complex.

Some relationships among Schaefer's serotypes and biological and biochemical characteristics were observed in strains of the Mycobacterium avium-Mycobacterium intracellulare complex. Strains belonging to serotypes 2 and 16 lacked the capacity to utilize n- and iso-butanols as the sole source of carbon in the presence of ammoniacal nitrogen. However, strains of serotype 2 grew at 45 C and lacked arylsulfatase activity (after 14 days), whereas strains of serotype 16 failed to grow at 45 C and showed positive arylsulfatase activity. Strains belonging to serotypes 8, 9, and 15 grew at 45 C, utilized n- and iso-butanols, and showed arylsulfatase activity.

Occurrence of Mycobacterium tuberculosis and strains of the Mycobacterium avium-M. intracellulare complex together in the sputum of patients with pulmonary tuberculosis.

Out of 97 strains of M. tuberculosis isolated from the sputum of the same number of patients, 11 were shown to consist of a mixed population of M. tuberculosis and a strain of the M. avium-M. intracellulare (MAI) complex. The most effective method for isolating strains of the MAI complex was to incubate the culture first at 42 degrees C for 3 weeks and then at 45 degrees C for 3 weeks. By this method, the growth of M. tuberculosis was suppressed, while the contaminant mycobacteria formed colonies.

Advanced technologies of cardiovascular nuclear medicine and their evaluation in clinical practice.

Currently available advanced methods of cardiovascular nuclear medicine for the diagnosis of ischemic heart disease were studied. The methods included the multigate method by a large capacity gamma camera-computer (128 KW memory with multilayer disc) system which made it possible to acquire the data of either the first pass study or the equilibrium study in "imaging mode". Analyzed data were displayed on a color CRT using our moving image system (MIS) and dynamic image thus obtained serve to help for the high sensitive observation of the regional wall motion as well as the global function of the ventricles. Myocardial tomography by a 7 pinhole collimator designed by us was also reported. The myocardial tomogram obtained was proved to show more sensitivity than two dimensional myocardial scan by the conventional collimator to detect smaller lesion and the lesions at the inferior or posterior wall of the left ventricle. The cardiovascular nuclear medicine with recent advanced technologies was thought to be sensitive and useful method for the diagnosis of the ventricular performance and the myocardial ischemia.
