Objective: To investigate the efficacy of imiquimod in women with residual or recurrent cervical intraepithelial neoplasia (rrCIN), compared with large loop excision of the transformation zone (LLETZ).

Design: Randomised controlled non-inferiority trial.

Setting: One academic and one regional hospital in the Netherlands.

Topical imiquimod could be an alternative, noninvasive, treatment modality for high-grade cervical intraepithelial neoplasia (CIN). However, evidence is limited, and there are no studies that compared treatment effectiveness and side effects of topical imiquimod cream to standard large loop excision of the transformation zone (LLETZ) treatment. A multi-center, nonrandomized controlled trial was performed among women with a histologic diagnosis of CIN 2/3.

Objective: To evaluate the efficacy and long-term outcome of repeat large loop excision of the transformation zone in women with residual or recurrent cervical intraepithelial neoplasia.

Methods: PALGA (the Dutch Pathology Registry), a database of deidentified cervical cytologic and histologic data, was used to examine women with cervical dysplasia who underwent two or more large loop excision of the transformation zone procedures between January 2005 and June 2015. We obtained cervical cytology and histology results.

Introduction: Since the implementation of human papillomavirus (HPV)-based screening for cervical cancer, the majority of cervical intra-epithelial neoplasia grade 2 (CIN2) lesions are high-risk (hr)HPV positive. Evidence on prognostic factors in hrHPV-positive CIN2 is lacking, hampering the individual counseling of women undergoing observation as routine management. The aim of this study is to identify prognostic factors for the spontaneous regression of hrHPV-positive CIN2.

Approximately 20-40% of high-grade Cervical Intraepithelial Neoplasia (CIN) regresses spontaneously, but the natural prognosis of an individual lesion is unpredictable. Gain of the chromosomal 3q region, which contains the human telomerase RNA gene on 3q26, is found in CIN lesions and cervical carcinoma and shows correlation with disease grade. The aim of this study is to assess whether 3q26 gain as a single genetic marker can predict the natural prognosis of high-grade CIN, by performing a review of the literature and pilot study.

Imiquimod has been studied as a noninvasive pharmacological treatment alternative to large loop excision of the transformation zone (LLETZ) for high-grade cervical intraepithelial neoplasia (CIN), to prevent long-term obstetric complications from surgical treatment. This study aims to investigate womens' preferences for treatment of high-grade CIN with imiquimod or LLETZ. A labeled discrete choice experiment was conducted among 100 women with abnormal cervical cytology in 5 hospitals in the Netherlands between March 2014 and December 2015.

This study aims to develop a prediction model for spontaneous regression of cervical intraepithelial neoplasia grade 2 (CIN 2) lesions based on simple clinicopathological parameters. The study was conducted at Maastricht University Medical Center, the Netherlands. The prediction model was developed in a retrospective cohort of 129 women with a histologic diagnosis of CIN 2 who were managed by watchful waiting for 6 to 24months.

Objective: The aim of the study was to assess awareness, attitudes, and current clinical experiences of gynecologists regarding imiquimod as a potential treatment modality for vaginal intraepithelial neoplasia (VAIN) and cervical intraepithelial neoplasia (CIN).

Materials And Methods: A 37-item questionnaire consisting of both multiple choice and open questions was sent to all Dutch gynecologists who regularly perform colposcopies in all 87 Dutch hospitals, in December 2014. The outcomes were assessed using descriptive statistics.

The natural history of high-grade cervical intraepithelial neoplasia (CIN) is largely unpredictable and current histopathological examination is unable to differentiate between lesions that will regress and those that will not. Therefore, most high-grade lesions are currently treated by surgical excision, leading to overtreatment and unnecessary complications. Prognostic biomarkers may differentiate between lesions that will regress and those that will not, making individualized treatment of high-grade CIN possible.

Objective: Children treated for sacrococcygeal teratoma (SCT) may experience functional sequelae later in life. It is not known whether SCT and associated problems affect the patient's general quality of life (QoL). In a national survey, we evaluated general QoL in adults treated for SCT during childhood and compared the results to reference values for the Dutch population.

Background: Sacrococcygeal teratoma resection often brings changes in pelvic anatomy and physiology with possible consequences for defecation, micturition and sexual function. It is unknown, whether these changes have any gynecological and obstetric sequelae. Until now four pregnancies after sacrococcygeal teratoma resection have been described and cesarean section has been suggested to be the method of choice for delivery.

We present a case of symptomatic perihepatic adhesions, which developed after a pregnancy complicated by hemolysis, elevated liver enzymes and low platelet (HELLP) syndrome, in which a subcapsular liver hematoma occurred. Our patient presented with complaints of persistent, severe right-sided upper abdominal pain. The complaints developed gradually, one year after a pregnancy that had been complicated by HELLP syndrome with a subcapsular liver hematoma.

Background And Aims: Studies evaluating the effect of arginine supplementation in human wound healing are inhomogeneous with conflicting results. This study aims to clarify the role of arginine supplementation in the healing of human skin graft donor sites.

Methods: 35 subjects undergoing skin autografting were randomly assigned to receive intravenous arginine (n = 16) or placebo (n = 19) for 5 days in a dose of 30 g of arginine or an isovolumetric amount of placebo (25.
