Knowledge of cervical cancer and attendance at cervical cancer screening: a survey of Black women in London.

Women from ethnic minority backgrounds are less likely to attend cervical screening, but further understanding of ethnic inequalities in cervical screening uptake is yet to be established. This study aimed to explore the socio-demographic and ethnicity-related predictors of cervical cancer knowledge, cervical screening attendance and reasons for non-attendance among Black women in London

The characteristic ultrasound features of specific types of ovarian pathology

Characterizing ovarian masses enables patients with malignancy to be appropriately triaged for treatment by subspecialist gynecological oncologists, which has been shown to optimize care and improve survival. Furthermore, correctly classifying benign masses facilitates the selection of patients with ovarian pathology that may either not require intervention, or be suitable for minimal access surgery if intervention is required. However, predicting whether a mass is benign or malignant is not the only clinically relevant information that we need to know before deciding on appropriate treatment. Knowing the specific histology of a mass is becoming of increasing importance as management options become more tailored to the individual patient. For example predicting a mucinous borderline tumor gives the opportunity for fertility sparing surgery, and will highlight the need for further gastrointestinal assessment. For benign disease, predicting the presence of an endometrioma and possible deeply infiltrating endometriosis is important when considering both who should perform and the extent of surgery. An examiner’s subjective assessment of the morphological and vascular features of a mass using ultrasonography has been shown to be highly effective for predicting whether a mass is benign or malignant. Many masses also have features that enable a reliable diagnosis of the specific pathology of a particular mass to be made. In this narrative review we aim to describe the typical morphological features seen on ultrasound of different adnexal masses and illustrate these by showing representative ultrasound images

The E2 protein of human papillomavirus type 8 increases the expression of matrix metalloproteinase-9 in human keratinocytes and organotypic skin cultures.

Non-melanoma skin cancer (NMSC) is the most frequent human cancer of Caucasian populations. Although the ultraviolet irradiation is a key contributor to the establishment of this keratinocyte malignancy, the infection by some types of human papillomavirus (HPV) has also been implicated in NMSC development. Cancers occur as a result of a complex series of interactions between the cancer cell and its surrounding matrix. The matrix metalloproteinases (MMPs) play a role in degrading the extracellular matrix. MMP9 is an important gelatinase involved in processes such as cell migration, invasion and metastasis. In this report, we demonstrated by EMSA experiments that the MMP9 promoter contains a binding site for the transcriptional regulator E2 of HPV8. Transient reporter gene assays showed that HPV8-E2 activated the MMP9 promoter in a dose-dependent manner in human epidermal keratinocytes. An E2 transactivation-defective mutant (I73L) as well as a DNA-binding deficient mutant (R433K) demonstrated no activation of the MMP9 promoter, suggesting that both an intact transactivation and DNA-binding domain are required for E2 activation of the MMP9-promoter. The functional role of the E2 binding site within the MMP9 promoter was also confirmed by mutating the E2 binding site. In organotypic cultures of human skin, an overexpression of MMP9 was observed in suprabasal layers of the HPV8 E2-expressing epidermis thus confirming the results of the monolayer cultures. These results demonstrate that the early gene E2 of HPV8 is able to increase the expression of MMP9 by direct activation of the MMP9-promoter
