Breast implants.

The emergency physician's day-to-day practice requires a broad range of knowledge of many aspects of medicine. Breast implants are a commonly implanted device and a working knowledge of their function and potential complications will aid emergency physicians in the care of their patients. Early postoperative complications, particularly hematomas and infection, require a close working relationship with the surgeons who perform the procedures. Knowledge of the long-term problems associated with all implant types will assist the emergency physician in making appropriate and timely referral.

Urine and the laboratory diagnosis of Chlamydia trachomatis in males.

OBJECTIVE: To determine whether the use of urine samples from male patients can replace urethral swabs for the rapid detection of Chlamydia trachomatis by the Pharmacia EIA. SETTING: The STD clinic, Adelaide, South Australia. PATIENTS: There were two separate groups of male patients. Group A (398) patients provided urethral specimens for the EIA and culture tests. The patients in Group B (356) provided an urethral swab and a urine sample for the EIA test. METHODS: The urine samples and urethral swabs were tested for the presence of C trachomatis by the Pharmacia Chlamydia EIA. In addition, the urethral swabs from Group A patients were cultured for the organism by standard cell cultures. The infected cell cultures were identified by an immunofluorescence test using a FITC-monoclonal antibody to C trachomatis (Kallestad). RESULTS: When the EIA was validated against culture, it showed a sensitivity of 100% and a specificity of 95% with the urethral swabs from Group A patients. The urine specimens were positive in 24% of those patients who yielded a positive EIA result in the urethral swabs. CONCLUSIONS: Although the EIA test on urethral swabs showed high sensitivity and specificity when validated against culture, our results showed that the use of urine samples cannot replace urethral swabs for the laboratory diagnosis of this sexually transmitted disease.

Severe functional declines, work disability, and increased mortality in seventy-five rheumatoid arthritis patients studied over nine years.

Seventy-five patients with rheumatoid arthritis (RA) were reviewed 9 years after an extensive evaluation which included quantitative measures of functional capacity. These patients had received multiple intraarticular injections of thiotepa with corticosteroids early in their course, but appear demographically and functionally similar to other RA patients who had not received this therapy. Severe morbidity was seen over the 9-year period in the 55 surviving patients, including significantly lower overall functional capacity in 92% of patients studied, lower grip strength in 93%, and longer button test results in 84%. Work disability occurred in 85% of patients under age 65 who had been working full-time at disease onset. There was increased mortality at the 9-year review, similar to most reported series of RA patients from referral centers; however, a significant increase in neoplasia, which was of concern because of the use of intraarticular thiotepa, was not seen. In terms of functional capacity, including responses to questions about ability to perform activities, walking time, and the button test, those patients who had died prior to review had significantly lower baseline values than did those who survived. Of the 75 patients, 20 had died and 51 had lost significant functional capacity over a 9-year period, documented by quantitative measures of functional capacity.
