Q: Abstract: Boerhaave's syndrome represents a diagnostic dilemma for the emergency physician. The prognosis of this truly life-threatening emergency is darkened by any significant diagnostic delay. Unfortunately, classic or expected symptoms and signs are frequently absent at presentation, a circumstance that leads to frequent misdiagnosis. Two cases of Boerhaave's syndrome with "atypical" clinical presentations are reviewed and discussed. It is clear that Boerhaave's syndrome should always be suspected in the evaluation of any sudden chest, abdominal, or back pain associated with emesis. However, emphasis should be placed on the fact that this entity may occur without emesis. The chest radiograph is the most helpful diagnostic aid. Undoubtedly, maintenance of a high degree of suspicion by the emergency physician for Boerhaave's syndrome will lead consistently to earlier diagnosis, and subsequent aggressive intervention should result in considerable reduction in rates of both morbidity and mortality.

Q: Abstract: Nine cases of suspected craniotomy flap osteomyelitis evaluated by combined bone and gallium scanning are presented. In six cases, the clinical data were inconclusive and evaluation by radionuclide imaging provided an accurate negative diagnosis. The other three cases considered positive by this technique were proven infected at subsequent exploration and flap removal. The use of radionuclide bone and gallium imaging should be considered in cases of possible craniotomy flap osteomyelitis.

Q: Abstract: We have developed a convenient system that can be used to iodinate monoclonal antibodies for diagnosis or therapy. A vial, previously coated with 1,3,4,6-tetrachloro-3a, 6a-diphenyl glycouril (iodogen), is used as a reaction vessel. Iodination and separation of bound and free iodide, using AG1-X8 ion exchange resin, are both accomplished in this vial. We found 90 +/- 4% of the iodide which was added was incorporated, respectively, into each of four different monoclonal antibodies evaluated. Approximately 90% of labeled antibody was recovered in each case. The monoclonal antibody OC125 was labeled to specific activities up to 25 mCi/mg. Immunoreactivities of 82 +/- 2% using 125I and 66 +/- 5% using 131I were achieved. As the radioiodination is done in one sealed vial and takes less than 15 min, this procedure is safe and can be performed in any nuclear medicine laboratory. The final product, which is sterile and apyrogenic, is suitable for diagnostic and radiotherapeutic applications.
