RESUMO
In August 1991, three rural Alaska Public Health dentists made a professionally significant return visit to the Soviet Far East. The city of Magadan was the site for the first actual demonstration of portable American dental equipment and treatment techniques in this remote region of Russia. This exchange was held at several clinical locations and took place during the time of the attempted USSR government coup.

Seventeen cases of abortions and stillbirths from a harem breeding colony of rhesus monkeys (Macaca mulatta) were studied to determine the role of aerobic bacteria in their etiology. Using histopathologic criteria correlated with bacterial cultures, the cause in 11 of 17 cases was found to be ascending infection with normal vaginal flora, most commonly gram-positive cocci, especially an alpha-hemolytic streptococcus (Streptococcus viridans). Actively breeding animals in the colony were screened for Str viridans, and it was determined to be a normal vaginal inhabitant that had the potential of becoming an opportunistic pathogen.

Two patients with longstanding Crohn's disease, who developed colonic carcinoma and showed associated "precancer" identical to that seen with ulcerative colitis, are reported. The first patient developed rectal adenocarcinoma at age 42 yr, 27 yr after the onset of symptoms while the second patient had a clinically silent small colonic carcinoma at the time of colectomy, 40 yr after the onset of disease. Both patients had characteristic Crohn's disease. In both patients, in addition to the carcinoma, there was multifocal "precancer" characterized by (a) epithelial dysplasia and (b) adenomatous growth pattern and villiform proliferation of the mucosa. These changes were identical to those associated with ulcerative colitis and, in both cases, were present adjacent to and distant from the infiltrating carcinomas. It is important to note that such epithelial changes, termed "precancer" in the setting of longstanding ulcerative colitis, can also occur in association with longstanding Crohn's disease. Further studies are needed to define the incidence of such precancerous changes in Crohn's disease more clearly and to evaluate the relationship between these changes and carcinoma. Careful evaluation of patients with longstanding Crohn's disease and "precancer" is warranted to exclude concomitant carcinoma.

A case of an intrauterine mummified fetus in a Macaca mulatta is described. The condition was detected in a member of a harem breeding colony, which exhibited vaginal bleeding. The mummified fetus was surgically removed and the mother made an uneventful recovery.
