RESUMO
We present a new surgical procedure, metaphyseal core decompression, to treat Kienböck's disease. Twenty-two patients were treated between 1976 and 1988 and were retrospectively reviewed. Sixteen were male and 6 female with an average age of 36 years (range, 18-64 years). The surgical technique involved curettage of the distal radius and ulna metaphyseal bone through small cortical windows. The average follow-up period was 10 years (range, 6-16 years). No postoperative complications were noted and no patient underwent additional surgical procedure. Sixteen patients were pain-free; 4 noted occasional pain. Twenty returned to their prior occupation. One patient had moderate pain and altered his occupation. Another had increasing pain and had x-ray evidence of advanced intercarpal arthritis. The average arc of wrist extension and flexion was 77% of the opposite wrist and the average grip strength was 75%. Long-term follow-up monitoring indicates that the metaphyseal core decompression produces results at least as good as other surgical procedures without any postoperative complications.

In order to evaluate interobserver and intraobserver agreement of the Frykman and AO classifications and their variations between assessors with different levels of experience, three hand specialists, a fellow and two senior residents classified radiographs of 200 fractures of the distal radius in anteroposterior and lateral views. Reproducibility was assessed by the use of the proportion of agreement and kappa coefficient between pairs of observers. The Frykman classification showed moderate interobserver reproducibility (kappa = 0.43) and good intraobserver reproducibility (kappa = 0.61). The experience of the reviewers did not significantly affect either of these. The AO system showed regular interobserver reproducibility (kappa = 0.37) and moderate intraobserver reproducibility (kappa = 0.57). The younger group obtained higher intraobserver agreement than the senior. Possible causes for the low reproducibility of both classifications are discussed together with a review of the literature. We do not recommend the Frykman or AO classifications for clinical application because of their questionable reproducibility.

For the purpose of identifying viral agents associated with acute respiratory tract infections (ARI) in children less than 5 years old, a longitudinal community study was undertaken in Montevideo, Uruguay, from May 1985 to December 1987. This report includes results obtained by cell culture and immunofluorescence techniques for detection of respiratory syncytial virus (RSV), influenza A and B viruses, parainfluenza 1 and 3 viruses, and adenovirus. Two populations were studied: children visited at home by pediatricians (group 1) and children with an ARI episode who attended an outpatient clinic (group 2). Nasopharyngeal aspirates were obtained at the time of an ARI episode: 858 from group 1 and 488 from group 2. Viruses were identified in 15.3% of group 1 specimens and in 17.6% of group 2 specimens. RSV was the most frequently recovered agent, accounting for 67.9% and 58.1%, respectively, of all viruses detected. The sensitivity and specificity of RSV isolation by cell culture are compared with detection by indirect immunofluorescence.
