Pseudomonas aeruginosa has been frequently detected from sputa around tracheostomy stuma with a high frequency of nosocomial infection among patients with an opportunistic infection. It is also reported to be difficult to treat lower respiratory infections when resistance to antibiotics for Pseudomonas aeyuginosa has developed. We discuss 15 patients, (8 males and 7 females) who underwent tracheostomy and in whom Pseudomonas aeyuginosa was isolated for 10 years from April 1993 to March 2003. Average age was 62.0 years old. All subjects were oral cancer patients. Pseudomonas aeyuginosa was detected from cultures in 15 of 19 patients (78.9%) . It was isolated from and had colonized the lower respiratory tract by 34.6 days on average after tracheostomy. Gradual change of sensitivity to antiobiotics and increase of drug tolerance were recognized. As drug tolerance may be affected by long-term administration of antibiotics, selection of antibiotics and period should be carefully considered to avoid the development of tolerance.

Soccer balls such as the Adidas Roteiro that have been used in soccer tournaments thus far had 32 pentagonal and hexagonal panels. Recently, the Adidas Teamgeist II and Adidas Jabulani, respectively having 14 and 8 panels, have been used at tournaments; the aerodynamic characteristics of these balls have not yet been verified. Now, the Adidas Tango 12, having 32 panels, has been developed for use at tournaments; therefore, it is necessary to understand its aerodynamic characteristics. Through a wind tunnel test and ball trajectory simulations, this study shows that the aerodynamic resistance of the new 32-panel soccer ball is larger in the high-speed region and lower in the middle-speed region than that of the previous 14- and 8-panel balls. The critical Reynolds number of the Roteiro, Teamgeist II, Jabulani, and Tango 12 was ~2.2 × 105 (drag coefficient, Cd ≈ 0.12), ~2.8 × 105 (Cd ≈ 0.13), ~3.3 × 105 (Cd ≈ 0.13), and ~2.4 × 105 (Cd ≈ 0.15), respectively. The flight trajectory simulation suggested that the Tango 12, one of the newest soccer balls, has less air resistance in the medium-speed region than the Jabulani and can thus easily acquire large initial velocity in this region. It is considered that the critical Reynolds number of a soccer ball, as considered within the scope of this experiment, depends on the extended total distance of the panel bonds rather than the small designs on the panel surfaces.
