- Continuous expression of E6- and E7-oncogenes of high-risk human papillomavirus (HPV) types is necessary for the development and maintenance of the dysplastic phenotype. The aim of the study was to determine the sensitivity and specificity of the APTIMA HPV mRNA assay (Hologic) in predicting future development of high-grade cervical intraepithelial neoplasia (CIN) among high-risk HPV-DNA-positive women with atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous epithelial lesion (LSIL) cytology.

- BACKGROUND: Both childhood trauma and violent behavior are important risk factors for suicidal behavior. The aim of the present study was to construct and validate a clinical rating scale that could measure both the exposure to and the expression of violence in childhood and during adult life and to study the ability of the Karolinska Interpersonal Violence Scale (KIVS) to predict ultimate suicide in suicide attempters.METHOD: A total of 161 suicide attempters and 95 healthy volunteers were assessed with the KIVS measuring exposure to violence and expressed violent behavior in childhood (between 6-14 years of age) and during adult life (15 years or older). The Buss-Durkee Hostility Inventory (BDHI), "Urge to act out hostility" subscale from the Hostility and Direction of Hostility Questionnaire (HDHQ), and the Early Experience Questionnaire (EEQ) were used for validation. All patients were followed up for cause of death and a minimum of 4 years from entering in the study.RESULTS: Five patients who committed suicide within 4 years had significantly higher scores in exposure to violence as a child, in expressed violent behavior as an adult, and in KIVS total score compared to survivors. Suicide attempters scored significantly higher compared to healthy volunteers in 3 of the 4 KIVS subscales. There were significant correlations between the subscales measuring exposure to and expression of violent behavior during the life cycle. BDHI, Urge to act out hostility, and EEQ validated the KIVS.CONCLUSIONS: Exposure to violence in childhood and violent behavior in adulthood are risk factors for completed suicide in suicide attempters. Behavioral dysregulation of aggression is important to assess in clinical work. The KIVS is a valuable new tool for case detection and long-term clinical suicide prevention.

- Background To monitor residual disease after treatment of high grade cervical intraepithelial neoplasia (CIN), cytology together with human papillomavirus (HPV) testing are commonly performed. Objectives To analyse the spectrum of HPV types before and after treatment. Study design This register-based study included 446 women treated for CIN2 or 3, where cytology samples had been HPV-tested before and after treatment by the use of the MGP-PCR Luminex HPV L1-DNA-assay identifying 39 HPV types, including 12 high risk (HR) HPV types. Results Before and after treatment, 706 and 248 HPV isolates were detected of 36 and 34 different HPV types, respectively. Among all the HR HPV isolates, type-specific persistency was observed among 14% (76/542) after treatment, compared to 34% (31/92) of low-risk (LR) HPV isolates (p < 0.001). Among the potential high risk (PHR) HPV isolates, 8.3% (6/72) persisted. Totally, 99% (440/446) and 40% (179/446) of the women were HPV-positive before and after treatment, respectively. At least one of the 12 HR HPV types was present in 91% (404/446) and 24% (109/446) of the women before and after treatment, respectively (p < 0.0001). HR HPV types were present both before and after treatment among 23% (102/446) of the women, and 16% (71/446) manifested at least one persistent HR HPV type. The sensitivity, specificity and negative predictive value of HR HPV testing for detection of residual high grade squamous intraepithelial lesion (HSIL) was based on the first cytology after treatment, and was 91.7% (95% CI: 61.5%–99.8%), 84.1% (95% CI: 80.0%–87.7%) and 99.7% (95% CI: 98.2%–100.0%), respectively. Conclusions About one out six treated women (16%) manifested at least one persistent HR HPV type, that was associated with recurrent or residual HSIL disease (odds ratio 58.1, 95% CI 7.4–457) (p = 0.0001). Testing for HR HPV demonstrated high sensitivity (92%) for residual HSIL. The higher persistency rate of LR HPV types suggests that they are more likely to be outside the treated area.

- Keratoacanthoma (KA) is difficult to histologically distinguish from squamous cell carcinoma (SCC). Therefore, although KA is a benign self-resolving skin lesion, KA is commonly treated as SCC. Biomarkers to distinguish KA and SCC would thus be desirable. In search for specific markers, paraffin-embedded tissue samples from 25 SCC and 64 KA were arranged in a tissue microarray (TMA) and stained for immunologic cell-markers CD3, CD20 and CD68 as well as for proteins considered of relevance in tumorgenesis, namely NFkappaB/p65, IkappaB-alpha, STAT3, p53, TRAP-1, pRB, phosphorylated pRb, Cyld, p21, p16(INK4), Survivin, Bcl-xL, Caspase 3, Bak, FLK-1/VEGF-r2 and Ki-67. In addition, the tumors were tested for presence of human papillomavirus by PCR. We detected that the two lesions differed significantly in expression of Bcl-xL which was present in 84% of the SCC compared with only 15% in the KA (p < 0.001). The lower expression of the antiapoptotic protein Bcl-xL in KA is consistent with a possible role of apoptosis in the regression of KA. (c) 2008 Wiley-Liss, Inc.
