[Symphysiotomy to relieve shoulder dystocia].

Symphysiotomy to manage shoulder dystocia is seldom used in the western world. For this reason, in well-resourced countries knowledge of its recuperation rate and the management of physical discomfort in the post-partum period is scarce. We describe two cases of symphysiotomy for shoulder dystocia.

Differentiated vulvar intraepithelial neoplasia is often found in lesions, previously diagnosed as lichen sclerosus, which have progressed to vulvar squamous cell carcinoma.

Lichen sclerosus is considered to be the precursor lesion of vulvar squamous cell carcinoma, of which only 2-5% progress to squamous cell carcinoma. Differentiated vulvar intraepithelial neoplasia (VIN) has been proposed to be the direct precursor lesion, but this is a recently recognized, and a difficult to diagnose, entity, which may easily be mistaken for a benign dermatosis. The aim of this study was to test the hypothesis that of all lesions that have been diagnosed as lichen sclerosus in the past, a part might currently be diagnosed as differentiated VIN, and to identify histopathological differences between lichen sclerosus lesions with and without progression to vulvar squamous cell carcinoma.

Hemoglobin level predicts outcome for vulvar cancer patients independent of GLUT-1 and CA-IX expression in tumor tissue.

Intratumoral hypoxia has been associated with poor prognosis in several solid tumors. The aim of this study was to determine whether the hypoxia-associated markers glucose transporter (GLUT)-1 and carbonic anhydrase (CA)-IX expression and preoperative hemoglobin (Hb) levels correlate with presence of inguinofemoral or distant metastases, and disease-free survival (DSS) in vulvar squamous cell carcinoma (SCC) patients. Vulvar SCC (n=103) were reviewed for histopathological characteristics by an expert gynecopathologist and stained for GLUT-1 and CA-IX.

Specific intraepithelial localization of mast cells in differentiated vulvar intraepithelial neoplasia and its possible contribution to vulvar squamous cell carcinoma development.

Aims: The aetiology of vulvar squamous cell carcinomas (SCC) that are not causally associated with high-risk human papillomavirus remains largely elusive. The aim of this study was to analyse the inflammatory response in its presumed precursor lesions, lichen sclerosus (LS) and differentiated vulvar intraepithelial neoplasia (dVIN), and provide evidence that dVIN is a likely precursor of vulvar SCC.

Methods And Results: Immunohistochemical analyses for CD4+, CD8+, CD20+, CD68+, S100+ and tryptase-positive immune cells were performed and quantified in LS (n = 7), dVIN (n = 19), SCC (n = 11), and normal vulvar tissue (n = 8).

The effect of vulvar lichen sclerosus on quality of life and sexual functioning.

Lichen sclerosus (LS) is a chronic skin disorder mostly seen on the female anogenital skin. The aim of this study was to evaluate the quality of life (QoL) and sexuality in female patients with LS and to compare their scores with healthy controls. In addition, we wanted to find factors associated with impaired sexual functioning in patients with LS.

High levels of p53 expression correlate with DNA aneuploidy in (pre)malignancies of the vulva.

The molecular pathogenesis of human papilloma virus-unrelated vulvar squamous cell carcinoma is not well known. Whether malignant progression of lichen sclerosus and differentiated vulvar intraepithelial neoplasia to vulvar squamous cell carcinoma could be accompanied by altered DNA content has not been studied extensively. DNA content in isolated nuclei of microdissected normal vulvar epithelium (n = 2), lichen sclerosus (n = 9), differentiated vulvar intraepithelial neoplasia (n = 13), and squamous cell carcinoma (n = 17) from 22 patients was measured via DNA image cytometry.

A patient with lichen sclerosus, Langerhans cell histiocytosis, and invasive squamous cell carcinoma of the vulva.

We report a patient with vulvar lichen sclerosus, Langerhans cell histiocytosis (LCH), and later vulvar cancer. In LCH, high amounts of non functional Langerhans cells are present in the affected tissue, making it possible that LCH may have contributed to vulvar cancer development in this patient.

The prognostic value of blood and lymph vessel parameters in lichen sclerosus for vulvar squamous cell carcinoma development: an immunohistochemical and electron microscopy study.

Objective: The objective of the study was to quantify vessel type and density in lichen sclerosus (LS) to find a marker for its malignant potential.

Study Design: Quantitative analysis was performed on paraffin-embedded tissue samples of 28 patients with LS (7 adjacent to vulvar squamous cell carcinoma, 21 solitary) and immunohistochemical staining for CD34 (vascular and lymphangiogenic lymph endothelial cells), D2-40 (lymphatic-specific marker), and alpha-SMA (pericyte marker). Electron microscopy was performed on fresh tissue.

Update on the sentinel lymph node procedure in vulvar cancer.

Currently, standard treatment for early-stage vulvar cancer typically includes wide local excision of the primary tumor and inguinofemoral lymphadenectomy. The morbidity of this treatment is high. The sentinel lymph node (SLN) procedure provides us with a technique for determining the status of the regional lymph nodes with less treatment-related morbidity.

Never forget medication as a cause: vaginal ulceration caused by nicorandil.

A patient was referred to our vulvar outpatient clinic because of a vaginal ulceration that persisted for 3 years and that had been unresponsive to any prescribed therapy. After a possible association was found with nicorandil therapy, this medication was stopped. Thereafter, the ulceration fully healed within 6 months.

The role of sentinel node biopsy in gynecological cancer: a review.

Purpose Of Review: In early-stage vulvar, cervical and endometrial cancer, lymph node status is the most important prognostic factor. Surgical treatment is aimed at removing the primary tumor and adequately staging the regional lymph nodes. As morbidity of regional lymphadenectomy is high, sentinel node biopsy is a technique with potential for adequate staging with less treatment-related morbidity.

The etiologic role of HPV in vulvar squamous cell carcinoma fine tuned.

Purpose: High-risk human papilloma virus (HPV) plays a role in the development of a subset of vulvar squamous cell carcinomas. Uncertainty exists about the true impact of HPV in this tumor type because conflicting reports have been published with diverging prevalence rates. This study was done to fine tune the role of high-risk HPV infection in vulvar squamous cell carcinoma development in relation to clinical prognosis.

Vulvar squamous cell carcinoma development after diagnosis of VIN increases with age.

Objective: The purpose of the present study is to investigate the trends in incidence of both usual (u) and differentiated (d) vulvar intraepithelial neoplasia (VIN) separately, their malignant potential and the relation with other HPV related anogenital lesions in the Netherlands during a 14-year-period.

Methods: The incidences of both types of VIN and vulvar SCC were retrieved from the Nationwide Netherlands Database of Histo- and Cytopathology. Population data were retrieved from the Database of Statistics Netherlands.

Does experience in colposcopy improve identification of high grade abnormalities?

Objective: This study investigates whether experience in colposcopy improves identification of high grade abnormalities. The sensitivity and positive predictive value (PPV) of colposcopy in identifying high grade intra-epithelial lesions (HSIL) performed by relatively inexperienced as compared to experienced colposcopists are evaluated.

Study Design: Of 18,421 colposcopies performed at the Royal Women's Hospital, Melbourne, Australia, between 1999 and 2004 by 5 senior and 11 junior colposcopists, the colposcopic impression was correlated with the histopathology result of the biopsy taken at 6020 colposcopies, with respect to the experience of the colposcopist.
