Autoflora in the upper respiratory tract of Apollo astronauts

The typical microbial inhabitants of the oral and nasal cavities of Apollo astronauts were identified before space flight and generally found to be similar to those previously reported for healthy male adults. Additional analyses of samples collected immediately after return of the Apollo 13, 14, 15, and 16 crew members to earth were performed to evaluate the effects of space travel on the microbial bioburden of the upper respiratory tract. In-flight cross-contamination and buildup of pathogens such as Staphylococcus aureus were noted, although significant increases in nonpathogenic species were absent. Other proposed alterations, such as dysbacteriosis (flooding of the mouth with a single species) and simplification of the autoflora, did not occur. Generally, the incidence and quantitation of each species after flight was within the preflight range, although the number of viable Haemophilus cells recovered from the mouth decreased significantly after space flight. Except for those minor alterations listed above, the aerobic and anaerobic bacterial components of the upper respiratory autoflora of Apollo astronauts was found to be stable after space flight of up to 295 h.     

Patient compliance in the treatment of respiratory tract infections

The survey on outpatients compliance in the treatment of respiratory tract infections was performed in Croatia during April 1996. A total of 213 physicians, 201 adult patients, and 178 parents of sick children were polled by the appropriate questionnaires. The results have shown that in the treatment of respiratory tract infections physicians commonly prescribe thrice-daily antibiotic regimens for 8-10 days. Concerning patients' knowledge, 85% of patients deem that regularity, and 64% that duration of antibiotic administration influences treatment outcome. Over 80% of patients are compliant with once-or twice-daily regimens, but only 50% take regularly and timely drugs that are dosed every 6 or 8 hours. Common reasons for irregular taking of antibiotics are forgetfulness and dosing during sleeping. In terms of appropriate duration of antibiotic therapy, about 20% of patients usually take antibiotic for 8-10 days, 60% for 5-7 days, and 20% for < or = 4 days. It may be concluded that the patients are poorly compliant with oral antibiotics treatment.     

A comparison of sevoflurane with halothane in outpatient adenotomy in children with mild upper respiratory tract infections

Our educational efforts produced several intersecting interdisciplinary groups: faculty, students, faculty/students and our community sites, with faculty, clinical staff, and students. As we worked through the issues, these interdisciplinary teams found that commitment to change, caring for patients, and open, honest communication were essential to keeping the project teams on track. We have increased our understanding of both the complexity and value of interdisciplinary collaborative education. The LIT faculty provided the initial guidance and support, the students energized the process, and our community sites made our learning and our contributions readily available to our patient populations. It is not easy to learn and teach the language and tools of continuous improvement, but doing so infinitely improves the educational process and the clinical outcome. We must learn to carefully listen to each other so that our patients can fully reap the benefits of our interdisciplinary team efforts. As a result of what we learned, the members of the George Team have expanded our motto to "Blessed Are the Flexible--and the Perseverant!"     

Differential diagnosis of allergic diseases of the upper respiratory tract

The author studied various manifestations of the most widely spread clinical forms of allergic diseases of the upper respiratory tract, namely, the bacterial, atopic and combined ones. In addition to clinical investigations laborotory, immunologic and functional tests were conducted. The difference in pathogenesis affected the clinical course of the disease. Some symptoms depended on the kind of sensibilization, others on how strongly pronounced the pathologic process was.
