Management of a primary malignant melanoma of uterine cervix stage IVA patient with radical surgery and adjuvant oncolytic virus Rigvir® therapy: A c…
2020
Abstract Primary malignant melanoma of the uterine cervix is a rare disease with poor prognosis and high recurrence rate. We used Rigvir® as adjuvant therapy for a stage IVA patient. Tolerability, overall and progression‐free survival are good.
Endometrial and Cervical Cancers
2021
Uterine corpus and cervical cancers are showing, in the last decades, increasing incidence and mortality in industrialized and developing countries, respectively; on the other hand, innovative therapeutic strategies are emerging for the management of advanced gynecological malignancies. Risk factors and predisposing conditions are widely and continually studied; thus, prevention, through lifestyle correction and/or validated screening tests, could represent a promising tool to diagnose earlier and reduce mortality of uterine cancers. Herein, management of endometrial and cervical tumors from diagnosis to commonly applied standards of care and experimental frontiers are depicted so as to pro…
Oral cancer, HPV infection and evidence of sexual transmission
2013
The incidence of oropharyngeal cancer and oral cancer is growing worldwide, both in young non-smokers and in young non-drinkers (smoking and drinking are considered the main risk factors). Epidemiologic studies suggest a strong association between the infection by human papillomavirus (HPV), especially types 16 and 18 (high oncological risk) which have already demonstrated their etiological role in anal tumours as well as in cervix cancer. There is clear epidemiologic evidence that both types of tumours relate to changes in sexual behaviour and that both are linked to sexual transmission of HPV. The number of oral and oropharyngeal cancer cases is rising nowadays, especially among young ind…
Intratumoral PO2 Histography as Predictive Assay in Advanced Cancer of the Uterine Cervix
1994
Experimental evidence suggests that the hypoxic fraction in a solid tumor may increase its malignant potential and reduce its sensitivity towards nonsurgical treatment modalities such as standard irradiation and certain anticancer agents1–5. However, the clinical importance of tumor hypoxia remains uncertain since valid methods for the routine measurement of intratumoral O2-tensions in patients have so far been lacking.
Presence of human papillomavirus and Epstein-Barr virus in the cervix of women infected with the human immunodeficiency virus
2001
The presence of human papillomavirus (HPV) and Epstein-Barr virus (EBV) was sought in cervical scrapings from 110 human immunodeficiency virus (HIV)-infected women to evaluate the role of these viruses as risk factors for squamous intraepithelial lesions of the cervix. By using PCR, presence of HPV-DNA and EBV-DNA was found in 60.9% (67/110) and in 10% (11/110) of clinical samples, respectively. Identification of oncogenic group of HPV by hybrid capture (HC II, Murex-Digene) indicated the presence of low-risk HPV in 13 (19.4%) patients, high-risk HPV in 28 (41.8%), and both types of HPV in 26 (38.8%) patients. Squamous intraepithelial lesions were present in 59 cases, being low-grade (n = 5…
Radiographic Investigation of Frequency and Location of Root Canal Curvatures in Human Mandibular Anterior Incisors In Vitro
2007
The aim of the present in vitro study was to evaluate the degree and location of root canal curvatures of mandibular anterior incisors. A total of 396 extracted human permanent anterior incisors (248 central and 148 lateral) were included in this investigation. Exclusion criteria were teeth with extensive carious lesions, restorations, and root canal treatment. The specimens were fixed in a special device and digitally x-rayed (Heliodent MD; Sirona, Benzheim, Germany; Merlin 2.1, Olympus/PerkinElmer, Waltham, MA) with the parallel technique. The distances from the cementoenamel junction (CEJ) to the first curvatures as well as the according angles were recorded. The results were analyzed de…
Increased Vascularity in Cervicovaginal Mucosa with Schistosoma haematobium Infection
2011
Background Close to 800 million people in the world are at risk of schistosomiasis, 85 per cent of whom live in Africa. Recent studies have indicated that female genital schistosomiasis might increase the risk of human immunodeficiency virus (HIV) infection. The aim of this study is to quantify and analyse the characteristics of the vasculature surrounding Schistosoma haematobium ova in the female genital mucosa. Methodology/Principal Findings Cervicovaginal biopsies with S. haematobium ova (n = 20) and control biopsies (n = 69) were stained with immunohistochemical blood vessel markers CD31 and von Willebrand Factor (vWF), which stain endothelial cells in capillary buds and established blo…
(A)symptomatic necrotizing arteritis of the female genital tract.
2000
Abstract Aims: The vasculitides represent a heterogenous set of disorders that differ in prognosis and response to therapy. Beside systemic vasculitides, the development of localized forms of arteritis is well known though uncommon and the etiopathogenesis is not yet definitely clear. Methods: Patients with necrotizing arteritis of the female genital tract proven by histology are studied in a retrospective analysis. Results: Three cases of necrotizing arteritis with histological features of panarteritis nodosa apparently confined to the female genital tract are presented. None of these patients had prior history of systemic vasculitis. The acute necrotizing vasculitis was confined only to t…
Intermediate filaments of normal and neoplastic tissues of the female genital tract with emphasis on problems of differential tumor diagnosis
1984
Cytokeratins of normal epithelia and of some neoplasms of the female genital tract were studied by immunofluorescence microscopy of frozen sections and by two-dimensional gel electrophoresis of cytoskeletal proteins from microdissected tissues. All normal epithelia were stained with the monoclonal cytokeratin antibody KG 8.13 whereas certain monoclonal antibodies stained only simple epithelia. As revealed by gel electrophoresis the normal epithelia of the ovarian surface, oviduct, endometrium and endocervix contained cytokeratin polypeptides Nos. 7, 8, 18 and 19. In contrast, stratified exocervical epithelium showed a much more complex pattern (polypeptides No. 1, 2, 4, 5, 6, 11, 13, 14, 15…
Scanning electron microscopy of the cervix uteri.
1974
Scanning electron microscopy has been used in the study of five cases of the cervix uteri: two normal cases; one case of indirect metaplasia; one case of carcinoma in situ whose colposcopic examination showed an erosio vera surrounded by leucoplasia, mosaic, base, and an area of atipic transformation zone and one case of invasive carcinoma.
