During the nine-year period from 1983 to 1991, a total of 242 patients (142 males and 100 females) presenting with Kawasaki disease were seen at one hospital. Among them, 25 (10%) patients demonstrated incomplete Kawasaki disease and 17 of these 25 (68%) lacked two of the six principal symptoms of Kawasaki disease, with the most frequently missing symptoms being cervical lymphadenopathy and polymorphous exanthema. The typical laboratory features of Kawasaki disease, such as elevated erythrocyte sedimentation rate, leukocytosis, anemia, positive C-reactive protein and thrombocytosis were also seen in the incomplete cases. None of the 25 patients underwent iv gamma-globulin therapy while in 1 (4%), transient dilatation of the coronary artery was recognized. Incomplete Kawasaki disease may therefore be characterized by a less frequent association of rash, cervical lymphadenopathy and coronary involvement.

Objectives: The purpose of this study was to evaluate the optimal upper threshold levels of a number of individuals and determine the most suitable upper threshold. Methods: A phantom model and ten patients were used in this study. The phantom was made of acrylic resin and urethane resin and had nine pillar-shaped air spaces. The subjects were ten female patients with jaw deformities who were not affected by respiratory disease. The optimal threshold levels were determined using the "calculation of CT value disparities" (CCTD) technique, which we devised. In other words, the mean CT values along two lines (air space and soft tissue) were calculated and the optimal threshold level was determined as the level that produced the maximum difference between the CT values measured inside and outside of the air-space border. Results: The optimal upper threshold levels of the nine phantom holes calculated using the CCTD technique in the front-on standing position and side-on standing position were 2434 HU and 2456 HU, respectively. The optimal upper threshold level of the ten patients calculated using the CCTD technique was 2472 HU. The true threshold level of each patient was defined as the optimal threshold level calculated using the CCTD technique. The mean threshold level was defined as 2472 HU. The absolute differences between the volume measurements obtained with these two measures were considered. Therefore, the no error values were 2460 HU and 2470 HU. Conclusions: We consider that the most suitable upper threshold level for extracting the airway is from 2460 HU to 2470 HU.

The midterm survival, hemodynamic variables, and exercise tolerance were similar and satisfactory in both lateral tunnel and extracardiac conduit groups; however, the incidence of cardiac-related events was significantly less frequent in the extracardiac conduit group. In the lateral tunnel group, careful observation is required to monitor the relationship of the dilating tendency of the intra-atrial tunnel and the development of late complications.
