  • Chlamydia trachomatis PCR (Cobas Amplicor) in women: endocervical specimen transported in a specimen of urine versus endocervical and urethral specimens in 2-SP medium versus urine specimen only
  • 2000

    • The sensitivity of Roche Cobas Amplicor Chlamydia trachomatis polymerase chain reaction (PCR) including the internal control (IC) programme to identify inhibition, was investigated on 3 different samples from women: (1) swab samples from the urethra and the cervix pooled in 2-SP transport medium, (2) swab sample from the cervix transported in a urine sample from the same patient, and (3) urine sample alone. Out of the 2412 patients, 193 (8.0%) were chlamydia positive and in 14 of these the results showed discrepancies between sampling methods. The sensitivity of PCR on urethra/cervix, urine/cervix and urine was 98.4% (190/193), 97.9% (189/193) and 93.3% (180/193) respectively. The higher sensitivity of PCR on urethra/cervix and urine/cervix as compared with urine alone was statistically significant. Without the IC, the sensitivity of PCR on urethra/ cervix, urine/cervix and urine would have been 95.9% (185/193), 94.8% (183/193) and 90.7% (175/193) respectively. Factors influencing the rate of inhibition were also studied.

  • Concentrations of polychlorinated biphenyls in blood and the risk for testicular cancer
  • 2004
  • Ingår i: International Journal of Andrology. - : Wiley. - 0105-6263 .- 1365-2605. ; 27:5, s. 282-290

    • An increasing incidence of testicular cancer has been reported from several western countries during the last decades. According to current hypothesis testicular cancer is initiated during the foetal period and exposure to endocrine disruptors such as some persistent organic pollutants has been of concern. We have previously reported the results for concentrations of polychlorinated biphenyls (PCBs), p,p'-dichlorodiphenyl-dichloroethylene (pp'-DDE), hexachlorobenzene (HCB) and chlordanes in 58 cases with testicular cancer, 61 age-matched controls and 44 case mothers and 45 control mothers. In that report, significant increase of odds ratio (OR) was found for sum of PCBs, HCB, trans- and cis-nonachlordane in case mothers. These data have now been further analysed for 37 congeners of PCBs. No significant differences were found among cases and controls. However, case mothers had significantly increased concentrations of a number of PCB congeners. A priori decided grouping of PCBs yielded for oestrogenic PCBs OR = 2.4, 95% confidence interval (CI) = 0.95-6.0, enzyme-inducing PCBsOR = 2.6, 95% CI = 1.03-6.5 and toxic equivalents (TEQ) yielded OR = 3.3, 95% CI = 1.3-8.4. These data further elucidate the role of foetal exposure to different PCB congeners in the aetiology of testicular cancer.

  • Increased concentrations of polychlorinated biphenyls, hexachlorobenzene, and chlordanes in mothers of men with testicular cancer

    • An increasing incidence of testicular cancer has been reported from several countries in the Western world during the last decades. According to current hypothesis, testicular cancer is initiated during the fetal period, and exposure to endocrine disruptors, i.e., xenoestrogens, has been of concern. In this investigation we studied the concentrations of the sum of 38 polychlorinated biphenyls (PCBs), p,p'-dichlorodiphenyl-dichloroethylene, hexachlorobenzene (HCB), and chlordanes, in 61 cases with testicular cancer and 58 age-matched controls. Furthermore, case and control mothers were also asked to participate, and 44 case mothers and 45 control mothers agreed. They were of similar age. In cases only the concentration on lipid basis of cis-nonachlordane was significantly increased, whereas case mothers showed significantly increased concentrations of the sum of PCBs, HCB, trans- and cis-nonachlordane, and the sum of chlordanes. Among case mothers the sum of PCBs yielded an odds ratio (OR) of 3.8, 95% confidence interval (CI), 1.4-10 was calculated using the median concentration for the control mothers as cutoff value. For HCB, OR = 4.4 (95% CI, 1.7-12), for trans-nonachlordane, OR = 4.1 (95% CI, 1.5-11), for cis-nonachlordane, OR = 3.1 (95% CI, 1.2-7.8), and for sum of chlordanes, OR = 1.9 (95% CI, 0.7-5.0). No consistent different risk pattern was found for seminoma. or nonseminoma testicular cancer.

  • Vestibular schwannoma, tinnitus and cellular telephones
  • 2003
  • Ingår i: Neuroepidemiology. - : S. Karger AG. - 0251-5350 .- 1423-0208. ; 22:2, s. 124-129

    • Cases with tinnitus after using analogue cellular telephones are presented. An increased odds ratio of 3.45, 95% confidence interval (CI) 1.77–6.76, was found for vestibular schwannoma (VS) associated with the use of analogue cell phones. During the time period 1960–1998, the age-standardized incidence of VS in Sweden significantly increased yearly by +2.53% (CI 1.71–3.35). A significant increase in the incidence of VS was only found for the latter of the two time periods 1960–1979 and 1980–1998. For all other brain tumors taken together, the incidence significantly increased yearly by +0.80% (CI 0.59–1.02) for the time period 1960–1998, although the increase was only significant for benign tumors other than VS during 1960–1979.
