Chlamydia in pregnant women: southeastern Wisconsin.

Three hundred forty-two pregnant women were screened for the presence of Chlamydia trachomatis in the endocervix using a direct fluorescent antibody test (MicroTrak, Syva Co.). The prevalence of C trachomatis infection was 11.7% in our urban, non-inner-city, family practice center. Single marital status was significantly associated with C trachomatis infection, but obstetrical factors were similar in patients with and without positive chlamydial smears. The use of non-culture techniques to screen community populations of pregnant women for C trachomatis is discussed.

Graded exercise stress test training in family practice and internal medicine residencies.

A mail survey of upper Midwest family practice and internal medicine residency program directors was performed to determine the prevalence and characteristics of exercise stress test training. Two mailings provided a 68% response rate for the 184 programs surveyed. Internal medicine programs were significantly more likely to offer exercise stress test training than family practice programs (57% vs 34%). Overall, an estimated 31% of family practice and internal medicine residency graduates are performing exercise stress tests in their practice. Programs provided an average of 7.3 hours of didactic instruction and 32.7 stress tests per resident. A minority (43%) had an established minimum number of exercise stress tests recommended for competency. Programs with and without exercise stress test training did not differ significantly with respect to age, size of program, or size of community. There were some interstate differences in the extent of exercise stress test training provided by family practice residency programs. Internal medicine programs were more likely to require a minimum number of treadmill tests. Otherwise there were few differences between family practice and internal medicine program instruction in exercise stress test training. Family practice program directors were more likely to believe that their residents should be taught this procedure and to include family physicians in their panel of instructors. Specific guidelines should be created to assure adequate stress test training for interested residents.

The epidemiology of blastomycosis in dogs: north central Wisconsin, USA.

The epidemiological features of 59 consecutive cases of blastomycosis in domestic dogs, from a single veterinary practice in Eagle River, Wisconsin over a 3-year period, were examined by owner interview. The control sample included: (i) all porcupine quill-injured dogs during this time period (outdoor exposed dogs); and (ii) every sixth dog receiving a rabies vaccination during the second year of study (representative of all dogs in the practice). The estimated mean annual incidence of blastomycosis in dogs in this region was 1420:100,000. Blastomycosis cases were more likely to reside within 400 m of a waterway (95%) than quill-injured dogs (63%, P < 0.001) or vaccinated dogs (74%, P = 0.001). Exposure to an excavation was significantly more likely among blastomycosis cases compared to quill-injured dogs, however, no differences were found for age, sex, hunting, swimming and reported exposure to beavers. The geographical clustering of cases in dogs is similar to that previously reported for humans in this region. A close proximity to waterways and an exposure to excavation are significant risk factors for blastomycosis.

An outbreak of human and canine blastomycosis.

In the summer and fall of 1988, three humans and one dog in a lakeshore community in northern Wisconsin were found to have blastomycosis on the basis of the results of cultures and histologic studies; the infection was also suspected in one human and four dogs on the basis of clinical data. Serologic testing with use of enzyme immunoassay for antibody to the A antigen of Blastomyces dermatitidis was performed for 77 additional human residents and visitors in the area an average of 9 months after the outbreak. Titers of antibody of greater than or equal to 1:32 were considered presumptive evidence of blastomycosis, and measurement of such titers enabled identification of 18 additional suspected cases in this group, compared with none in a control group (n = 40). Of the 22 humans with confirmed and suspected cases, 16 (73%) were asymptomatic. Epidemiologic and meteorologic data gathered during this period suggested an associated between this outbreak and the presence of dust from excavation for a hotel across the lake. The result of this study further confirm the common occurrence of self-limited and subclinical infection with B. dermatitidis and suggest that excavation in an area endemic for B. dermatitidis is a risk factor for human and canine infection.

Chlamydia and incidental carcinoid tumor in spontaneous abortion.

Maternal Chlamydia trachomatis infections have been associated with premature rupture of the membranes, preterm labor, premature birth, and fetal wastage. Women with acute infection may be at particular risk. We report the case of an unexplained second trimester spontaneous abortion with serologic evidence of recent infection with C. trachomatis. Serum IgG antibody titer ultimately exceeded 1:10,240. This patient also had an incidental finding of appendiceal carcinoid tumor. While treatment of asymptomatic chlamydial infections in early pregnancy is controversial, we suggest that delaying treatment may result in fetal loss.

Prevalence of Legionella in pharyngeal secretions of patients with pharyngitis.

A serological investigation has suggested that Legionella pneumophila may be associated with sore throat in adults. In a study of 177 adults and children with acute pharyngitis, Legionella species were not isolated from pharyngeal cultures, which utilized selective and nonselective buffered charcoal-yeast extract media. Group A beta-hemolytic streptococci were isolated from 14 percent of the 177 symptomatic patients. Throat cultures from 88 asymptomatic control subjects were negative for Legionella and beta-hemolytic streptococci. Further studies are needed to determine if Legionella species are associated with acute pharyngitis.

Resident attrition from family practice residencies: United States versus international medical graduates.

BACKGROUND: Attrition of residents from family practice residency programs may cause significant problems for faculty, residents, and patients. The objective of this study was to determine international medical graduates' attrition rate from family practice residencies, compared with US medical school graduates. METHODS: Surveys were sent to all family practice residency program directors asking them to calculate their attrition rate for a 10-year period. RESULTS: The overall response rate was 56.6%, but interpretable responses were received from 45% of all civilian, continental US family practice residencies. Responding programs did not differ from all family practice programs with respect to program overall. Of those residents leaving, 63% did so to enter other specialties. The attrition rate was 18.5% for international graduates, compared with 7.8% for US graduates (P < .0001). International graduates enrolled outside of the National Resident Matching Program (NRMP) were most likely to leave programs before completion. CONCLUSIONS: Attrition rates from family practice residency programs are higher for international medical graduates than for US graduates. International graduates enrolled outside of the NRMP were most likely to leave a program.

Candida parapsilosis infection in a rose thorn wound.

Candida parapsilosis should be recognized by primary care physicians as an important nosocomial pathogen, which is also frequently associated with sporadic skin and appendage infections. Its association with environmentally acquired skin ulcers can mimic fixed cutaneous sporotrichosis.

Identification of Blastomyces dermatitidis in the stool of a dog with acute pulmonary blastomycosis.

We report the identification of Blastomyces dermatitidis by microscopic examination of a direct faecal smear from a dog with pulmonary blastomycosis. A simultaneously obtained faecal culture grew Blastomyces dermatitidis. The fungus was also cultured from a transtracheal sample from this same dog. This report suggests that yeast-phase cells of B. dermatitidis may be recovered in the stool of dogs with pulmonary blastomycosis following transit through the gastrointestinal tract of swallowed infected sputum. Implications regarding the ecology of Blastomyces dermatitidis are discussed.
