Prevalence of vulval lichen planus in a cohort of women with oral lichen planus:an interdisciplinary study
2006
BACKGROUND: Lichen planus (LP) is a mucocutaneous inflammatory dermatosis that frequently involves the oral and genital mucosae. Patients with LP affecting these sites are often seen by oral medicine specialists or gynaecologists who work in isolation and depend heavily on histopathologists to help them in confirming the diagnosis. There are few studies in the literature combining the experiences of these specialists who share the care of patients with both oral and genital LP. OBJECTIVES: To estimate the prevalence of vulval LP (VLP) in a cohort of patients with histologically confirmed oral LP (OLP). METHODS: The study group consisted of 42 women histologically diagnosed with OLP. The mea…
Evidence for and Against Hypoxia as the Primary Cause of Tumor Aggressiveness
2003
In clinical trials, tumor hypoxia has consistently been associated with tumor aggressiveness. The evidence for an association between hypoxia and metastasis and more rapid tumor progression and death is seen in uterine cervical cancer, and sarcoma of soft tissue. Evidence is building in prostate, vulva, head and neck, and breast cancers. A major question is whether hypoxia precedes tumor aggressiveness or whether aggressive tumors incidentally are also hypoxic.
Light-induced resistance of the keratin network to the filament-disrupting tyrosine phosphatase inhibitor orthovanadate.
2003
Epidermal keratinocytes respond to low-dose light irradiation by inducing signaling cascades that lead to long-term effects on gene transcription thereby protecting cells against damage. In contrast, little is known about immediate light-induced alterations of structural proteins. We have made the intriguing observation that light produces fundamental changes in the properties of the keratin filament system of cultured epidermoid A-431 cells. A short light exposure (1–10 min) causes the keratin cytoskeleton to become immediately resistant to the tyrosine phosphatase inhibitor orthovanadate, which otherwise disrupts the keratin filament network completely in just a few minutes. This protecti…
Ecological, morphological and genetic characterization of sympatric Haemonchus spp. parasites of domestic ruminants in Mauritania
1995
SUMMARYThe 4 species of ruminants (dromedary, zebu cattle, sheep and goat) in arid areas of Mauritania harboured Haemonchus spp. as the most frequent internal parasite. This was a rare situation where the 3 putative species, H. longistipes (dromedary), H. placet (zebu cattle) and H. contortus (sheep and goat) occurred sympatrically. The study was undertaken on hosts slaughtered at the Nouakchott abattoir, on the basis of monthly collection of worms. The environment was very unfavourable to H. placei and unfavourable to H. contortus, as intensity of infection remained low throughout the year, whereas infection in the dromedary was 10 to 20-fold higher. The survival strategies during the long…
Personalized Treatment of Vulvar Cancer
2022
Vulvar cancer (VC) accounts for 5% of all gynecologic cancer and the most common histological type is squamous cell carcinoma (up to 90%)
Molecular mechanisms in developmental biology.
1996
Some general molecular mechanisms underlying development are described. Namely: those involved in the differentiation of the R7 receptor in Drosophila embryonic retina; those involved in the determination of embryonic axes and in polar cell differentiation, in Drosophila; those involved in the determination of the AB and P cell lineage and in vulva differentiation in Caenorhabditis embryos.
Vulvar involvement in pediatric Crohnâs disease: a systematic review
2018
Purpose: The aim of the study is to report a systematic review (from 2000 to 2017) of all pediatric cases of vulvar Crohnâs disease (VCD) and to highlight the key-points for a correct diagnosis and management of this rare condition. Methods: An electronic search using the Pubmed/Medline, Scopus, EMBASE, Cochrane database and Google Scholar database was performed according to PRISMA guidelines. Results: Twenty pediatric studies and 22 cases of VCD were included for analysis. All the articles reported a single case, except two articles where two cases, respectively, are described. Clinical vulvar examination showed the following main manifestations: vulvar erythema (9/22 cases, 40.9%), vulv…
Estudio piloto del tratamiento del liquen escleroso vulvar mediante tejido adiposo asociado a plasma rico en plaquetas autólogos
2020
Estudio piloto del tratamiento del liquen escleroso vulvar mediante tejido adiposo asociado a plasma rico en plaquetas autólogo. 1. Introducción. El Liquen escleroso (LE) es una enfermedad inflamatoria crónica, mediada por Linfocitos T (LT), de etiología desconocida que afecta fundamentalmente a la piel genital. Aunque La etiología exacta del LE es desconocida, se considera una enfermedad de origen multifactorial y cada vez se aboga más por el mecanismo autoinmune basado en su asociación con otras enfermedades de este tipo (Tiroiditis Hashimoto, alopecia Areata, vitíligo y anemia perniciosa) hasta en un 21-28% de los casos. La prevalencia en la población general se estima en 1 de cada 300-1…
Subcutaneous Vulvar Flap Viability Evaluation With Near-Infrared Probe and Indocyanine Green for Vulvar Cancer Reconstructive Surgery: A Feasible Tec…
2021
Introduction: Vulvar cancer is a rare condition affecting older women and accounts for 3–5% of all gynecological cancers. Primary surgical treatment involves the removal of a large amount of tissue for which reconstructive surgery is often necessary with a high rate of postoperative complications. Despite several techniques for the evaluation of vulvar flap viability have been proposed, many methods cannot be performed during surgery and require expensive devices often missing in a gynecological clinic. This study aims to verify the feasibility and the safety of the vulvar flap viability evaluation through a near-infrared endoscopic probe and Indocyanine green (ICG) tracer in a small group …
Efficacy and tolerability of a plant-based, multi-component cream (Ginetrox®) in vulvovaginal disorders of the genitourinary syndrome during menopaus…
2017
BACKGROUND Genitourinary syndrome of menopause (GSM) is a symptomatic condition including vaginal dryness, irritation, dyspareunia and recurrent urinary tract infections which affects 40-54% of post-menopausal women. Although several estrogen-based therapies are available, it is generally preferable to avoid hormonal therapy, particularly in women with mild symptoms or at risk for estrogen-responsive neoplasia. Therefore, the most common treatment options are over-the-counter vaginal creams for symptomatic relief. METHODS Thirty-three postmenopausal women suffering from GSM were enrolled in this observational study. A multi-component cream (Ginetrox®, Indena, Milan, Italy) was applied on th…
