The increased detection of cervical intraepithelial neoplasia when using a second biopsy at colposcopy.

OBJECTIVE: It has been suggested that colposcopy can miss a significant percentage of high-grade cervical intraepithelial neoplasia (CIN2+). Improved disease ascertainment was evaluated by taking multiple lesion-directed biopsies. METHODS: In a cross-sectional multicenter study in the Netherlands and Spain, 610 women referred to colposcopy following abnormal cervical cytology results were included. Multiple directed biopsies were collected from lesions and ranked according to impression. A non-directed biopsy of normal-appearing tissue was added if fewer than four biopsies were collected. We evaluated the additional CIN2+ yield for one and two directed biopsies. Colposcopic images were reviewed for quality control. RESULTS: In women with at least two lesion-directed biopsies the yield for CIN2+ increased from 51.7% (95%CI; 45.7-57.7) for one directed biopsy to 60.4% (95%CI; 54.4-66.2, p<0.001) for two biopsies. The highest CIN2+ yield was observed in women who were HPV16-positive, had high-grade squamous intraepithelial lesion (HSIL) cytology, and high-grade colposcopy impression. The yield increased from 83.1% (95%CI; 71.5-90.5) with one directed biopsy to 93.2% (95%CI; 83.8-97.3) with two directed biopsies. Only 4.5% additional CIN2+ were detected in biopsies not targeting abnormal areas on the cervix. CONCLUSIONS: A second lesion-directed biopsy is associated with a significant increase in CIN2+ detection. Performing a second lesion-directed biopsy and using a low threshold for abnormality of any acetowhitening should become the standard clinical practice of colposcopy.

The impact of human papillomavirus genotype on colposcopic appearance: a cross-sectional analysis.

OBJECTIVE: To study colposcopic performance in diagnosing high-grade cervical intraepithelial neoplasia or cervical cancer (CIN2+ and CIN3+) using colposcopic characteristics and high-risk human papillomavirus (hrHPV) genotyping. DESIGN: Cross-sectional multicentre study. SETTING: Two colposcopy clinics in The Netherlands and Spain. POPULATION: Six hundred and ten women aged 17 years and older referred for colposcopy because of abnormal cytology. METHODS: A cervical smear was obtained. Colposcopists identified the worst lesion, graded their impression and scored the colposcopic characteristics of the lesions. Up to four biopsies were collected, including one biopsy from visually normal tissue. MAIN OUTCOME MEASURES: CIN2+ and CIN3+, positive for HPV16 or other high-risk HPV types (non-16 hrHPV-positive). RESULTS: The mean age in HPV16-positive CIN2+ women was 35.1 years compared with 39.1 years in women with other hrHPV types (P = 0.002). Sensitivity for colposcopy to detect CIN2+ was 87.9% (95%CI 83.2-91.5), using colposcopic cut-off of 'any abnormality'. The remaining CIN2+ were found by a biopsy from visually normal tissue or endocervical curettage (ECC). Detection of CIN2+ by lesion-targeted biopsies was not different between HPV16-positive women [119/135; 88.1% (95%CI 81.2-92.9)] and non-16 hrHPV-positive women [100/115; 87.0% (95%CI 79.1-92.3); P = 0.776]. In multivariate analysis, 'acetowhitening' [odds ratio (OR) 1.91, 95%CI 1.56-3.17], 'time of appearance' (OR 1.95, 95%CI 1.21-3.15) and 'lesion >25% of visible cervix' (OR 2.25, 95%CI 1.44-3.51) were associated with CIN2+. CONCLUSIONS: In this population following European screening practice, HPV16-related CIN2+ lesions were detected at younger age and showed similar colposcopic impression as non-16 hrHPV high-grade lesions. There was no relationship between any of the colposcopic characteristics and HPV16 status.

Impaired sexual function in women with systemic sclerosis: a cross-sectional study.

OBJECTIVE: To compare sexual functioning and distress in women with systemic sclerosis (SSc) with that in healthy controls and determine the association between disease characteristics and sexual function. METHODS: We conducted a cross-sectional study of 69 women with SSc (ages 18-60 years) and 58 healthy, age-matched controls. Assessment included the Female Sexual Function Index (FSFI), Female Sexual Distress Scale (FSDS), Hospital Anxiety and Depression Scale, Short Form 36 health survey, sociodemographic characteristics, and in patients only, the Health Assessment Questionnaire. RESULTS: Of 69 eligible patients with SSc, 37 (54%) responded, in addition to 37 (64%) of 58 controls. The FSFI total score and the subscale scores for lubrication, orgasm, arousal, and pain were significantly lower and the FSDS scores were significantly higher in patients with SSc. Longer disease duration and higher levels of marital dissatisfaction were significantly associated with low sexual function in patients with SSc. Longer disease duration, more depressive symptoms, and the use of antidepressants were significantly associated with sexual distress. Multivariate analyses indicated that marital distress was the only variable significantly associated with low sexual function in patients with SSc (beta = 0.40, P < 0.05), whereas depression was the only variable significantly associated with sexual distress (beta = 0.32, P < 0.05). The same pattern of associations was found in the healthy control group. CONCLUSION: Women with SSc reported significantly impaired sexual functioning and more sexual distress then healthy controls. Impaired sexual functioning and sexual distress were associated with marital distress and depressive symptoms. These results indicate that in daily practice, inquiring about sexuality and screening for depressive symptoms is indicated in every patient with SSc, irrespective of their clinical characteristics.

Integration is the art of decomposition.

A growing demand for integrating stand-alone information systems with an HIS can be observed. Different forms of integration can be distinguished: technical integration, user interface integration, and integration of the information service. The integration of the information service appears to be especially difficult. An integrated information service can only be achieved when the applications use each other's information services. We will discuss three approaches for letting applications belonging to another system utilize the necessary information service of a host system. The first approach makes use of the user interface, and the necessary information service has to be extracted from the service to a user. Another, often used, approach is the extension of the applications with coupling modules. The coupling modules communicate messages and translate them into the context of the application. The applications are modified scarcely and the coupling modules have to supply the necessary information services. When the coupling problem is more complex (e.g., a larger set of data is to be exchanged interactively), a growing effort will be needed for these adapting modules. A better approach is to split the application into building blocks. Applications are composed of building blocks. The application, which should deliver the integrated information service, is also composed of such building blocks. The building blocks are designed to offer information services that can be used by other systems as well. If we succeed in decomposing the applications into suitable building blocks, an integrated information service could be more easily achieved.
