Ethical concerns in occupational screening programs.

Preventive and anticipatory programs for identifying workers at higher-than-normal risk for occupational injury and/or disease can now draw on an expanding net of sophisticated diagnostic tests. New genetic screening tests may use reagents developed through recombinant DNA technologies, including cDNA probes for genetic variants such as HLA B27 associated with late-appearing disability. Assessments of the readiness of these technologies to be incorporated into standard occupational policy turn on their predictive value, applications, and the locus of control of the data which they generate. The question of responsibility for health protection and obligations accruing to those who uncover genetically fixed risk status has major ethical implications. Issues of potential stigmatization, discrimination, and protection of equal employment opportunity must be resolved before these tests are put into practice. The possible use of genetic testing to assure minimal risk and its equitable distribution among workers is highlighted as a possible benefit of this new applied technology.

High prevalence of syphilis detected through a jail screening program. A potential public health measure to address the syphilis epidemic.

BACKGROUND: In June 1990, a syphilis initiative was undertaken to help control New York's most extensive syphilis epidemic since the 1940s. METHODS: To evaluate the usefulness of syphilis screening in local jails, were reviewed demographic and syphilis screening data from a county jail in an area with a high prevalence of syphilis that has routinely tested incoming inmates. RESULTS: Of 12,685 inmates, 9797 (77%) were screened for syphilis, and 321 (3.3%) had a positive test result; 258 (80%) of the positive results were confirmed. Data were available for 244 of the inmates with a confirmed positive result: 162 (67%) had newly diagnosed syphilis (overall rate, 1.6%), 112 of whom had early syphilis; 50 (20%) had been previously treated for syphilis; and 32 (13%) were unavailable for follow-up. Of 162 inmates with newly diagnosed syphilis, 122 (75%) were treated in jail, and 40 were treated after their release from jail. The median time from screening to treatment was 17 days. The median jail stay was 45 days for inmates who were evaluated for treatment vs 5 days for those who were unavailable for follow-up. CONCLUSIONS: Screening inmates for syphilis was a productive public health measure, as inmates accounted for 20% of the county's syphilis morbidity. Given the high prevalence of syphilis among inmates and the inability to reach them for treatment after release, strategies are needed to rapidly screen and treat inmates before their release from jail.

[The role of epidemiologic research of the natural history of cancer for evaluating cancer screening programs--a prospective study of colorectal polyps on the occurrence of colorectal cancer].

In order to elucidate the natural history of colorectal polyps and to examine the effectiveness of endoscopic polypectomy in reducing the incidence of colorectal cancer, we conducted a retrospective cohort study of all patients who had undergone endoscopic examination at the Center for Adult Diseases, Osaka in 1970-82. The study subjects consist of 653 non-polyp cases and 431 colorectal polyp cases including 222 cases treated by endoscopic polypectomy. These were followed up until the end of 1985 by the method of a record linkage with the Osaka Cancer Registry's file. The colorectal polyp group and the endoscopic polypectomy group experienced 4.4 and 2.9 times, respectively, as much incidence of colorectal cancer as the non-polyp group. The magnitude of the prevented fraction by the use of endoscopic polypectomy was estimated at 31.3%. A large-scale and long-term study is necessary to elucidate the original study purpose.

Hospitalization rates in female US Army recruits associated with a screening program for Chlamydia trachomatis.

BACKGROUND: A volunteer program to test non-healthcare-seeking women for genital Chlamydia trachomatis infection was instituted at the US Army's largest basic training center and evaluated for its effectiveness in reducing sequelae. GOAL: To compare hospitalization rates between women with positive test results for C trachomatis and those with negative results, and between women tested and those not tested for C trachomatis. STUDY DESIGN: For this study, 28,074 women who entered the Army in 1996 and 1997 were followed for hospitalizations through December 1998. Of these women, 7053 were tested for C trachomatis, and 21,021 were not screened. Hospital admissions were calculated per person-year, and adjusted relative risks were determined. RESULTS: The overall prevalence of C trachomatis in the screened group was 9.1%. The relative risk of hospitalization for pelvic inflammatory disease in the screened cohort was 0.94 (95% CI, 0.69-1.29), as compared with those not screened. The relative risk of hospitalization for any reason was 0.94 (95% CI, 0.90-0.99). Among women screened, no difference was found in pelvic inflammatory disease hospitalizations between women with positive test results who were being treated for C trachomatis and those with negative test results. CONCLUSIONS: The investigated C trachomatis intervention program for female Army recruits was associated with a lower overall hospitalization rate in screened volunteers, as compared with unscreened women. The pelvic inflammatory disease hospitalization rate in women with C trachomatis who were screened and treated was similar to that observed in uninfected women.

Prospective evaluation of a first trimester screening program for Down syndrome and other chromosomal abnormalities using maternal age, nuchal translucency and biochemistry in an Australian population.

BACKGROUND: A combination of maternal age and ultrasound assessment of the nuchal translucency (NT) has been used in the first trimester to screen for chromosomal abnormality. In the United Kingdom, the addition of NT screening was shown to be beneficial. AIMS: To report the sensitivity of combined first trimester biochemistry and ultrasound screening for Down syndrome in an Australian private practice specialising in obstetric ultrasound. METHODS: A prospective study in a private obstetric ultrasound practice. Over 22 months, 2121 patients were screened and data was analysed for sensitivity (detection) and false positive rates for all chromosome abnormalities. RESULTS: There were 17 chromosomal abnormalities, five of which were Down syndrome. Using maternal age alone or age and biochemistry, four of the Down syndrome cases were detected for a 29 and 19% false positive rate, respectively. Using age and NT or age, NT and biochemistry, all the Down syndrome cases were detected, for a false positive rate of 5.7 and 7.2%, respectively. The difference in detection rates for Down syndrome or other chromosomal abnormalities, using the four screening methods, did not reach statistical significance. However, the false positive rates in screening methods without ultrasound to assess the NT was significantly higher (P < 0.01). CONCLUSIONS: A combination of maternal age, NT and maternal serum biochemistry gives a high detection rate for both trisomy 21 and other chromosomal abnormalities. Down syndrome screening using either maternal age alone or age in combination with first trimester biochemistry conferred screen positive rates significantly higher than when combined with NT.
