Introduction: Many countries have adopted active surveillance in women with cervical intraepithelial neoplasia grade 2 (CIN2), leaving the lesion untreated. However, there is a lack of consensus on the eligibility criteria for active surveillance across countries, with some abstaining from active surveillance in women with human papilloma virus 16 (HPV16) or a high-grade cytology. Here, we aimed to describe the distribution of HPV genotypes, age, and cytology in women undergoing active surveillance for CIN2.

A better understanding of HPV natural history is useful for clinical counseling of women attending screening and to accurately inform health prevention strategies such as screening and HPV vaccination. We evaluated the extent of latent HPV infections in older women with a history of abnormal cytology.

Patients diagnosed with early-stage cervical cancer have a good prognosis, however, 10-20% suffer from local or distant recurrent disease after primary treatment. Treatment options for recurrent cervical cancer are limited.

The prepuce is pivotal in its etiology. Other proposed etiological factors are the subject of dispute and include occluded urinary exposure, autoimmunity, immunodysregulation, and infectious agents.

Methods: Nasal and oropharyngeal swabs of 152 controls and 152 patients with an RTI were included.
Aims: To assess safety and tolerability and explore pharmacodynamics and efficacy of omiganan in external anogenital warts (AGW) and vulvar high-grade squamous intraepithelial lesions (HSIL).
Methods: Two randomized controlled trials in patients with external AGW and vulvar HSIL were conducted. Patients received topical omiganan 2.

In clinical practice, the diagnosis of lower respiratory tract infections (LRTIs) is based on culture. The aim of this study was to evaluate whether a stepwise approach using microbiota analysis, species-specific quantitative real-time (q)PCRs and culture has the potential to be a more accurate and efficient diagnostic approach than culture alone. Sixty-two sputa obtained in a routine clinical setting from patients with a suspected LRTI were included.

Recently we found in Curaçao a low incidence of HPV16 and 18 in cervical cancer compared to the standard world population. We aimed to determine HPV-prevalence, HPV-genotype distribution and associated risk-factors in women from Curaçao.

On Curaçao, legal and illegal prostitution practice is high and the promiscuous lifestyle is common. We aimed to gain insight in HPV-genotype prevalence in cervical scrapes of female sex workers (FSW) and related risk factors in comparison with women not working in the sex industry.

We prospectively evaluated the association between β genus human papillomaviruses (βPV) and keratinocyte carcinoma in OTRs. Two OTR cohorts without cSCC were assembled: cohort 1 was transplanted in 2003-2006 (n = 274) and cohort 2 was transplanted in 1986-2002 (n = 352).

Objective: To investigate the prevalence of HPV genotypes in invasive cervical cancers (ICC) and cervical intraepithelial neoplasia (CIN) grade 1, 2 and 3 in Curaçao.
Background: For selecting therapy, it is important to distinguish different types of keratinocytic neoplasia. It is sometimes difficult to make histopathologic diagnosis, especially in organ transplant recipients (OTR) who develop numerous lesions.
Methods: To investigate p16 immunostaining in different types of keratinocytic neoplasia in OTR, we studied 59 actinic keratoses (AK), 51 Bowen' s disease (BD), 63 squamous cell carcinomas (SCC), 16 benign keratotic lesions (BKL) from 31 OTR patients and 25 controls (eczema and psoriasis).
A proportion of human immunodeficiency virus (HIV)-infected patients develop persistent, stigmatizing human papillomavirus (HPV)-related cutaneous and genital warts and anogenital (pre)cancer. This is the first study to investigate immunogenetic variations that might account for HPV susceptibility and the largest to date to categorize the HPV types associated with cutaneous warts in HIV-positive patients. The HLA class I and II allele distribution was analyzed in 49 antiretroviral (ART)-treated HIV-positive patients with persistent warts, 42 noninfected controls, and 46 HIV-positive controls.

Multiple reports have described cases of wart resolution following quadrivalent HPV vaccination. We report the case of a patient with chronic oral papillomas with resolution after quadrivalent HPV vaccination and perform a review of the literature.

KCs are the most common cancers in Caucasians, with the major risk factor being ultraviolet (UV) light exposure. A possible role for Beta-HPV types (BetaPV) in the development of KC was suggested several decades ago, supported by a number of epidemiological studies.

Methods: MSM aged ≥18 years were included in Amsterdam (the Netherlands) in 2010-2011, and followed up 6 months later. Participants completed risk factor questionnaires.
Background: High-grade anal intraepithelial neoplasia (AIN) is present in many human immunodeficiency virus (HIV)-positive men who have sex with men. The major etiologic factor is infection with an oncogenic human papillomavirus (HPV) genotype. We investigated whether individual components of high-grade AIN are caused by single HPV types.

A total of 111 samples, corresponding to 79 skin lesions abscised from 17 kidney transplant recipients, have been analyzed. The initial PCR analysis demonstrated that β-HPV-DNA was highly present in our tumor series (85%).

Objective: It has been reported that approximately 10% of low grade squamous intraepithelial lesions (LSIL) progress to high grade squamous intraepithelial lesions (HSIL) within a 2-year follow up. The factors related to lesion progression are currently unknown. The aim of the study was to identify prognostic markers of the course of LSIL.

In the general population, these sites (particularly oropharyngeal SCC) may be associated with infection with human papillomavirus (HPV). In FA and DC, however, the majority of HNSCC occur in the oral cavity.

Objectives: Within a pragmatic randomised controlled trial, we examined whether subgroups of common and plantar warts have a favourable natural course or response to treatment based on wart-associated HPV type.
Study Design: Consecutive patients with new common or plantar warts were recruited in 30 Dutch family practices.
Background: Epidemiological data on cutaneous wart-associated HPV types are rare.
Objectives: To examine the prevalence of cutaneous wart-associated HPV types and their relation with patient characteristics.
Study Design: Swabs were taken from all 744 warts of 246 consecutive immunocompetent participants and analysed by a broad spectrum HSL-PCR/MPG assay.
Human papillomaviruses (HPV) of the genera alpha, mu, and nu induce benign tumors of the cutaneous epithelia that constitute a significant burden for immunocompromised adults. Currently, no gold standard for genotyping of these HPV types exists. In this study, we describe the prevalence of genus alpha, mu, and nu HPV types in cutaneous warts.

The viral DNA load may be an important determinant of pathogenicity, but there are currently no baseline epidemiological data relating to load in people without SCC. We investigated DNA-loads of eight beta-PV types previously associated with risk of SCC.
