ABSTRACT
One of the applications for circular external fixators is the treatment of large-bone defects which may be difficult to manage with conventional methods. Successful results have been reported with the use of circular external fixators, particularly in the treatment of infected tibial pseudoarthroses and those with bone loss. In this study, a total of 43 cases with tibial bone defects (18 infected) as a result of high-velocity gun-shot injuries were treated with circular external fixators between January 1, 1988 and December 31, 1995. The mean follow-up period was 50 months (range: 28-98 months) after the removal of the Ilizarov device. Satisfactory union was obtained in 40 cases without any major complication or additional surgical intervention, in spite of the large and in some cases infected defects. We conclude that this is a safe method for the treatment of infected or noninfected tibial bone defects.

INTRODUCTION: Increased federal attention to nursing research has prompted professional nursing organizations to develop research programs identifying areas of scientific knowledge most needed for professional and clinical practice. The study purpose was to identify the National Flight Nurses Association's (NFNA's) research priorities. METHODS: A two-round Delphi technique was used, with systematic surveys in Round I mailed to 500 NFNA members. Responses from 127 members were coded to form the Round II survey that was completed by members at the NFNA meeting in St. Louis in October 1993. RESULTS: According to frequency scores, issues of highest priority relate to specialty and nonspecialty team, crew configurations, clinical indications for transport, airway management, educational preparation and continuing education. CONCLUSION: Identified priorities support development of research studies and programs that lead to increased knowledge, facilitate collaborative studies and also provide a basis for research funding.

For rapid and sensitive screening of lipid biochemical abnormalities of scaling skin disorders a sequential, one-dimensional high-performance thin-layer chromatographic method (HPTLC) has been developed. All major human stratum corneum lipid classes, i.e., cholesterol sulfate, glucosylceramides, six major ceramide fractions, free sterols, free fatty acids, triglycerides, sterol esters, squalene, and n-alkanes, are separated and quantitated after a stepwise development of a single silica gel 60 HPTLC-plate using three consecutive solvent systems. Reproducible results have been obtained by degradative charring as well as fluorescence detection. By fluorescence detection the method is particularly suitable for the determination of minor amounts of cholesterol sulfate and other sterols.
