RESUMEN
This study investigated secondary traumatic stress (STS) and secondary posttraumatic growth (SPG) in a sample of Dutch police family liaison officers (N = 224). Our study had two aims: (a) to identify potential risk and protective factors for STS and (b) to investigate the association between STS and SPG. None of the risk (caseload and a personal trauma history) and protective factors (age, work experience, and support by supervisors and coworkers) identified in previous research correlated with STS. However, a small positive association was found between STS and SPG. In the discussion section we warn against the use of interventions that aim to prevent STS until more is known about risk and protective factors for STS and provide directions for future research.

We offered voluntary counseling and testing (VCT) for HIV and syphilis to women attending three public sexually transmitted infection (STI) clinics in Bangkok, Thailand from May 2004 to June 2006. The testing was performed at either one of three STI clinics in Bangkok or at mobile VCT in the same area as the outreach activity. Six-hundred eighty-four women were tested. The HIV prevalences among the street-based sex workers, brothel-based sex workers and other women in these areas not reporting sex work who tested in the clinics were 45.8% (38/83), 4.2% (10/236) and 9.9% (28/284), respectively. The prevalences of syphilis in these groups were 13.3%, 2.1%, and 2.6%, respectively. Street-based sex work and longer duration of sex work were independent risk factors for HIV in-fection (p < 0.001 and p = 0.02, respectively). HIV and syphilis prevalences were 21.0% and 3.7% among 81 street-based sex workers accepting mobile VCT, The street-based sex workers in Bangkok had substantially higher HIV and syphilis prevalences than other sex workers. Street-based sex workers should be sampled during routine surveillance to obtain systematic information on disease preva-lence and risk behaviors in this group.

BACKGROUND: Almost half of all new HIV infections in Thailand occur among low-risk partners of people infected with HIV, so it is important to include people infected with HIV in prevention efforts. METHODS: Risk for HIV transmission was assessed among people with HIV attending routine care at the National Infectious Disease Institute in Thailand. Sexual risk behaviour, sexually transmitted infection (STI-syphilis, gonorrhoea, chlamydia, trichomoniasis and genital ulcers) prevalence and HIV disclosure status were assessed. Patients were provided with STI care, risk-reduction and HIV disclosure counselling. RESULTS: Baseline data were assessed among 894 consecutive people with HIV (395 men and 499 women) from July 2005 to September 2006. Unprotected last sex with a partner of unknown or negative HIV status (unsafe sex) was common (33.2%) and more likely with casual, commercial or male-to-male sex partners than with steady heterosexual partners (p = 0.03). People receiving antiretroviral treatment were less likely to report unsafe sex (p<0.001). Overall, 10.7% of men and 7.2% of women had a STI (p = 0.08). More women than men had disclosed HIV status to their steady partners (82.5% vs 65.9%; p = 0.05). CONCLUSION: Indicators for HIV transmission risk were common among people attending HIV care in Bangkok. Efforts need to be strengthened to reduce unsafe casual and commercial sex and to increase HIV disclosure from men to their partners. A strategy for STI screening and treatment for people with HIV in Thailand should be developed.

To determine the discriminative capacity of human papillomavirus (HPV) DNA testing for recurrent and residual cervical dysplasia, 43 patients with abnormal cytology after treatment for cervical dysplasia were tested for the presence of HPV DNA by PCR. An endocervical curettage was performed in all patients for histological examination. Sixteen of the 43 patients showed moderate or severe dysplasia. The HPV test was positive in all 16 patients with recurrent or residual dysplasia and negative in 12 of the 27 patients without dysplasia. The sensitivity and specificity of the HPV test were 100 and 44%, respectively. The likelihood ratio of a positive HPV test was 1.8, whereas a negative HPV test had a likelihood ratio of 0.12. Testing for the presence of HPV has the potential to select patients without recurrent or residual cervical dysplasia who have an abnormal cytological smear. This may have clinical implications, since unnecessary diagnostic conizations may be avoided in patients with abnormal cytology after treatment for cervical dysplasia and a negative HPV test.

OBJECTIVE: Current screening protocols for cervical cancer dictate that patients with smears read as mild or moderate dysplasia of the uterine cervix undergo colposcopy, although approximately half these women do not prove to have high-grade squamous intraepithelial lesions. The aim of this study was to determine whether human papillomavirus testing is capable of discriminating between high- and low-grade squamous intraepithelial lesions so as to be useful in reducing the number of colposcopic examinations. STUDY DESIGN: We tested 190 consecutive patients with smears read as mild or moderate dysplasia for the presence of human papillomavirus deoxyribonucleic acid by use of two different polymerase chain reactions with the consensus primer pairs CPI/IIG and MY09/11. Typing was carried out by direct sequence analysis of the CPI/IIG amplimers. The MY09/11 amplimers were detected in enzyme-linked immunosorbent assay format with the SHARP (Solution Hybridization Assay for PCR Products) Signal System with two probe mixtures (A and B) to detect nononcogenic and oncogenic human papillomavirus types. The human papillomavirus test results were compared with the histologic diagnosis, which was regarded as the reference standard. RESULTS: Fifty-six of the 190 patients had high-grade squamous intraepithelial lesions. The sensitivity was 96% for the CPI/IIG test and 95% for the MY09/11 polymerase chain reaction plus SHARP Signal System when probe B only was used. The specificity was 33% for the CPI/IIG test and 40% for the MY09/11 polymerase chain reaction plus SHARP Signal System when probe B was used. CONCLUSION: A negative CPI/IIG or SHARP Signal System probe B test can select, respectively, 44 or 54 of the 134 patients without high-grade squamous intraepithelial lesions. The use of these human papillomavirus tests as a secondary triage in patients with smears that were read as mild or moderate dysplasia could prevent those patients from undergoing unnecessary colposcopy. However, respectively, 2 or 3 of the 56 patients who have high-grade squamous intraepithelial lesions would be missed by human papillomavirus testing.

OBJECTIVES: The aim of this study was to investigate the prevalence of human papillomavirus (HPV) after treatment for cervical dysplasia. STUDY DESIGN: The presence of HPV was investigated in cervical scrapes of 91 patients, before and after treatment, using consensus primers in the polymerase chain reaction. RESULTS: Before treatment for cervical dysplasia, 89 of 91 patients (98%) were HPV-positive compared with 28 of 91 patients (31%) after treatment. The HPV type present before treatment was found in the scrapes of only 9 of 89 patients (10%). Detection of HPV after treatment was associated with human immunodeficiency virus infection and incomplete conization. CONCLUSION: The HPV type present before treatment was frequently cleared by treatment for cervical dysplasia.

BACKGROUND: The presence of human papillomavirus (HPV) DNA in relation to cervical cytology was evaluated after treatment of cervical dysplasia. METHODS: Forty patients, 22 with normal and 18 with abnormal cytology (mild or moderate dyskaryosis), with a history of cervical dysplasia were selected. Only patients with HPV DNA positive biopsies obtained before treatment were included. The presence of HPV was assessed in cervical smears at least 1 year after treatment of cervical dysplasia by using a polymerase chain reaction (PCR) with consensus primers (CPI/IIG). HPV typing was done by direct sequence analysis of the CPI/IIG PCR generated amplimers. RESULTS: Smears from 3 of the 22 patients with normal cytology after treatment were positive for HPV DNA (14%). HPV DNA positive smears were found in 13 of the 18 patients with abnormal cytology after treatment (72%) (relative risk: 5.3; 95% confidence interval: 1.78-15.75). In 11 of the 16 HPV DNA positive smears (69%), the HPV type was different from that before treatment. In 35 of 40 patients, the HPV type before treatment could not be detected after treatment (88%). CONCLUSIONS: A minority of the patients with normal cytology after treatment of cervical dysplasia had detectable HPV DNA. In contrast, a high prevalence of HPV DNA was found in cervical smears of patients with abnormal cytology after treatment of cervical dysplasia. After treatment, none of the patients with abnormal cytology but HPV DNA negative smears had recurrence of cervical intraepithelial neoplasia. This suggests the value of supplementary HPV DNA testing during follow-up of patients treated for cervical dysplasia.

In order to investigate the reliability of detection of human papillomavirus (HPV) DNA in cervical smears, we have compared the performance of two HPV PCR systems, the CPI/IIG and MY09/11 primer-mediated PCRs and the Hybrid Capture System HPV DNA detection test (hybrid capture assay), in detecting HPV DNA in cervical smears. We also included in our study the MY09/11B PCR plus SHARP (solution hybridization assay for PCR products) Signal System. This SHARP Signal System was recently developed to detect MY09/11B-generated biotinylated PCR products. The detection rate of the hybrid capture assay was lower than those of the CPI/IIG and MY09/11 PCRs and the MY09/11B PCR plus SHARP Signal System. The detection rates of the CPI/IIG PCR and the MY09/11B PCR plus SHARP Signal System were similar and higher than that of the conventional MY09/11 PCR system. The agreement beyond chance of the PCR methods was nearly perfect (kappa value between 0.82 and 0.84). The agreement beyond chance of the hybrid capture assay and the PCR methods was fair to good (kappa value between 0.64 and 0.70). The systems detected HPV DNA in different but overlapping sets of smears. Our results indicate that each of the detection methods alone underestimates the prevalence of HPV.
