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.
Vaginal progesterone decreases preterm birth and neonatal morbidity and mortality in women with a twin gestation and a short cervix: an updated meta‐…
2017
Objective To assess the efficacy of vaginal progesterone for the prevention of preterm birth and neonatal morbidity and mortality in asymptomatic women with a twin gestation and a sonographic short cervix (cervical length ≤ 25 mm) in the mid-trimester. Methods This was an updated systematic review and meta-analysis of individual patient data (IPD) from randomized controlled trials comparing vaginal progesterone with placebo/no treatment in women with a twin gestation and a mid-trimester sonographic cervical length ≤ 25 mm. MEDLINE, EMBASE, POPLINE, CINAHL and LILACS (all from inception to 31 December 2016), the Cochrane Central Register of Controlled Trials, Research Registers of ongoing tr…
Complementary and Innovative Method in Genital HPV Testing for Cervical Cancer Prevention
2020
Abstract Considering actual SARS-COV 2 pandemic, the comfort and time of the female patient’ trend is to minimize the time spent in the doctor’s office, so that auto-testing is a solving problem in this context. This paper aims at the importance of self-collected urine and vaginal samples, since actual studies are showing that is a complementary method in HPV-testing and a screening method for prevention of cervical cancer. Genital HPV infection is responsible for approximately 99% of cervical cancers, and is considered a sexually transmitted disease. Given that eight out of ten patients have at least one episode of HPV infection in their lifetime, there is a need for a method of early dete…
Low rate of oral human papillomavirus (HPV) infection in women screened for cervical HPV infection in Southern Italy: A cross-sectional study of 140 …
2009
Even though the natural history of cervical and oral human papillomavirus (HPV) infection has been investigated intensely, the possibility that HPV may infect both sites in the same subject is not well documented. This study investigated the frequency of concurrent oral and cervical HPV infection in southern Italian women, in the light of some selected socio-behavioral variables. One hundred forty women (mean age: 36 years), with known cervical HPV status, were analyzed for oral HPV. Age, smoking/drinking habits, clinical and socio-behavioral history were assessed by personal interviews. Oral mucosal cells were collected by oral brushing and HPV DNA was sought by the use of nested PCR ampli…
Función vesical y calidad de vida tras histerectomía radical con preservación nerviosa en pacientes con cáncer de cérvix. en pacientes con cáncer de …
2015
A nivel mundial, aproximadamente medio millón de mujeres son diagnosticadas anualmente de cáncer de cérvix . La supervivencia a los 5 años de esta enfermedad, es superior al 90 % en los estadios precoces, lo cual ha hecho que se dirija la atención a la calidad de vida que tienen estas pacientes. La edad de las pacientes y el buen pronóstico hace que, además de asegurar buenos resultados oncológicos, se requiera como objetivo asegurar una mínima invasión y se persiga minimizar los efectos secundarios y secuelas derivadas del tratamiento . La cirugía radical del cáncer de cérvix inicial tiene como objetivo el extirpar el cérvix y el cuerpo uterino junto con el tejido paracervical y parametria…
Ligneous Cervicitis in a Woman With Plasminogen Deficiency Associated With an Atypical Form of Microglandular Hyperplasia
2013
A 19-yr-old woman with previously diagnosed clear cell adenocarcinoma was referred to the Charité for further treatment. Biopsies were taken from the cervix, the endometrium, pseudomembranes in the peritoneum, and sentinel lymph nodes. The morphologic picture of pseudomembranes and inflammation together with the provided information about plasminogen deficiency of the patients led to the hypothesis of ligneous cervicitis. The previously taken biopsies of the adenocarcinoma were reevaluated and showed a clear cell lesion. Further immunohistochemical examination with antibodies against p16, Ki67, CEA, and p53 could not prove its malignant character. As a result we diagnosed an atypical form o…
