Oral Human Papillomavirus in Women With High-Grade Cervical Intraepithelial Neoplasia.

Objective: This study was designed to investigate the co-prevalence of cervical and oropharyngeal human papillomavirus (HPV) infection in patients with HPV-related high-grade disease of the uterine cervix (high-grade squamous intraepithelial lesion [HSIL]).

Materials And Methods: In a prospective cohort study, women with abnormal cervical cytology admitted to our colposcopy units received HPV testing of the uterine cervix and the oropharynx via smear. From a subset of patients, oral lavage was collected to compare detection rates of HPV DNA between lavage and swab.

Oral HPV prevalence in women positive for cervical HPV infection and their sexual partners: a German screening study.

The incidence of human papillomavirus (HPV) associated oropharyngeal squamous cell cancer (OSCC) is on the rise. With the HPV-positive uterine cervix as a reservoir, HPV-positive OSCC is discussed as a sexually transmitted disease. Mechanisms of HPV transmission to the oral cavity are poorly understood.

Sexual activity and function after surgical treatment in patients with (pre)invasive vulvar lesions.

Purpose: Sexual activity (SA) and sexual function (SF) are central outcome measures in women affected by preinvasive (vulvar intraepithelial neoplasia, VIN) and invasive (vulvar cancer, VC) vulvar lesions. Data on sexuality after treatment are scarce.

Methods: Validated questionnaires including the female sexual function index (FSFI-d) were provided to 166 women with a history of VIN and VC who attended the colposcopy units of the University Medical Center Hamburg-Eppendorf and Asklepios Medical Clinic Altona for follow-up between March 2011 and June 2012.

Human papillomavirus-type persistence patterns predict the clinical outcome of cervical intraepithelial neoplasia.

Background: Persistent infection with high-risk (HR) human papillomavirus (HPV) genotypes is required for the development of cervical carcinoma, and integration of HPV testing into cervical screening programs is under investigation. For the clinical value of HPV testing to be fully established, genotyping studies are needed to identify HR HPV persistence in samples of known cytology and histology, and to determine the relationship with clinical outcome. To date, methods for genotyping have been research-based, and subject to variation.

No confirmed case of human papillomavirus DNA-negative cervical intraepithelial neoplasia grade 3 or invasive primary cancer of the uterine cervix among 511 patients.

Objective: This study was undertaken to analyze the prevalence and peculiarities of high-grade cervical neoplasias that are not associated with human papillomavirus (HPV) DNA.

Study Design: Four hundred nineteen women with a first-time diagnosis of cervical intraepithelial neoplasia grade 3 and 92 women with cervical cancer were examined prospectively with a commercially available HPV DNA test. Negative samples were re-tested by polymerase chain reaction (PCR) with general and type-specific primers while the corresponding histology specimens were evaluated by immunohistochemistry.

High-throughput approaches for the discovery and optimization of new olefin polymerization catalysts.

The discovery of new olefin polymerization catalysts is currently a time-intensive trial-and-error process with no guarantee of success. A fully integrated high-throughput screening workflow for the discovery of new catalysts for polyolefin production has been implemented at Symyx Technologies. The workflow includes the design of the metal-ligand libraries using custom-made computer software, automated delivery of metal precursors and ligands into the reactors using a liquid-handling robot, and a rapid primary screen that serves to assess the potential of each metalligand-activator combination as an olefin polymerization catalyst.

MMP-1 and MMP-2 in the cervix uteri in different steps of malignant transformation--an immunohistochemical study.

Objectives: Enzymatic degradation of the extracellular matrix (ECM) represents a key element in the multistage process of tumor invasion and metastasis. This process requires extensive degradation of ECM components such as basement membrane collagen (type IV) and interstitial collagen (type I, II, III). Matrix metalloproteinase-2 (MMP-2) specifically cleaves collagen type IV, the major collagen of the basement membrane.

Factors associated with an increased risk of prevalent and incident grade III cervical intraepithelial neoplasia and invasive cervical cancer among women with Papanicolaou tests classified as grades I or II cervical intraepithelial neoplasia.

Objective: Women with Papanicolaou tests classified as cervical intraepithelial neoplasia grade I or II are treated conservatively in many countries. However, these women are at an increased risk of having underlying prevalent and incident grade III cervical intraepithelial neoplasia and invasive cancer. This study was undertaken to identify factors that could predict these clinically important disease states.
