Prevalence of herpes simplex, Epstein Barr and human papilloma viruses in oral lichen planus.
2011
Objectives: The aim of the present study was to assess the prevalence of Herpes Simplex virus, Epstein Barr virus and Human Papilloma virus -16 in oral lichen planus cases and to evaluate whether any clinical variant, histopathological or demographic feature correlates with these viruses. Study Design: The study was conducted on 65 cases. Viruses were detected immunohistochemically. We evaluated the histopathological and demographic features and statistically analysed correlation of these features with Herpes Simplex virus, Epstein Barr virus and Human Papilloma virus-16 positivity. Results: Herpes Simplex virus was positive in six (9%) cases and this was not statistically significant. The …
Periodontal disease and sjogren syndrome: a possible correlation?
2009
Sjögren syndrome (SS) is a chronic autoimmune rheumatic disease characterized by a progressive lymphocytic infiltration of exocrine glands, especially salivary and lachrymal ones, leading to xerostomia, parotid gland enlargement, and xerophthalmia. The aim of this study is to describe the capillaroscopic pattern of the interdental papilla in patients with SS and to evaluate a possible correlation with periodontal disease. Methods: A total of 25 patients affected by SS and 25 healthy controls were examined. The patients with conditions that compromise microcirculation, such as diabetes, hypertension, hyperlipidemia, or some pharmacological treatments, were not included in the study. All the…
Tas1R1-Tas1R3 taste receptor variants in human fungiform papillae.
2009
International audience; Monosodium glutamate as well as metabotropic and ionotropic glutamate receptor agonists have been reported to be perceived as umami by humans. In spite of the fact that Tas1R1-Tas1R3 has been shown to mediate most of the glutamate taste sensation in mice other candidate receptors have been put forward for which a clear role in detection is still lacking. This work was aimed at investigating the molecular determinants underlying umami taste detection in humans. First, we show evidence supporting expression of Tas1R1 and Tas1R3 but not mGluRs in the fungiform papillae of several individuals. Next, we report a number of naturally occurring l-glutamate taste receptor var…
Novel rearrangements involving the RET gene in papillary thyroid carcinoma.
2018
Abstract Background In the field of gene fusions driving tumorigenesis in papillary thyroid carcinoma (PTC), rearrangement of the proto-oncogene RET is the most frequent alteration. Apart from the most common rearrangement of RET to CCDC6, more than 15 partner genes are yet reported. The landscape of RET rearrangements in PTC (“RET-PTC”) can notably be enlarged by modern targeted next-generation sequencing, indicating similarities between oncogenic pathways in other cancer types with identical genetic alterations. Methods Targeted next-generation sequencing was performed for two cases of BRAF-wild type PTC with confirmation of the results by Sanger sequencing. A “UniProt” database research …
Detection of oncogenic human papillomavirus genotypes on spermatozoa from male partners of infertile couples
2013
Objective To evaluate the prevalence of human papillomavirus (HPV) sperm infection and its correlation with sperm parameters in patients who attended a fertility clinic. Design Cross-sectional clinical study. Setting University-affiliated reproductive medicine clinic. Patient(s) A total of 308 male partners of couples undergoing in vitro fertilization techniques. Intervention(s) Specimens of semen were collected from all patients. Main Outcome Measure(s) Sperm parameters were evaluated according to the World Health Organization manual. The presence of HPV DNA was researched by the combined use of two HPV assays and a highly sensitive nested polymerase chain reaction assay followed by HPV ge…
Hashimoto Thyroiditis Coexistent with Papillary Thyroid Carcinoma
2005
Several studies report a higher rate of papillary thyroid carcinomas (PTC) in patients with Hashimoto thyroiditis (HT), indicating a possible correlation between the two diseases. We studied a group of 89 subjects undergoing surgery for thyroid carcinomas compared with a control group of 89 subjects operated on for normofunctioning goiter, and a second group of 47 patients undergoing total thyroidectomy for HT. Association with HT was found in 19 of the 71 PTC subjects (26.7%) and in 8 goiter patients (8.9%), which was a significant difference ( P < 0.02). Thirteen of the HT patients, mostly with the nodular form, showed coexistent PTC (27.6%). HT and PTC coexisted in several morphologi…
2',5'-Oligoadenylate synthetase activity analysis and human papilloma virus typing as prognostic factors in patients with recurrent respiratory papil…
2004
Objective: Determination of early prognostic factors in patients with recurrent respiratory papillomatosis is extremely important, so the major goal of our prospective, multicentre study was to evaluate (1) the feasibility of various factors to determine prognosis of the clinical course,as well as (2) the response to interferon-alpha therapy in recurrent respiratory papillomatosis. Methods: Forty-two patients with recurrent respiratory papillomatosis were treated with interferon-alpha (3 MU/m2 three times per week; mean therapy duration was 2.7 ± 1.8 years)in 1983–1994 and followed-up until 2003. Human papilloma virus (HPV) type, recurrent respiratory papillomatosis severity and 2′,5′-oligo…
Use of Interferon-Alpha in Recurrent Respiratory Papillomatosis: 20-Year Follow-up
2005
Objectives: The aim of this study was analysis of the results of use of interferon-α (IFN-α) in patients with recurrent respiratory papillomatosis (RRP) and correlation of the results with human papillomavirus (HPV) type. Methods: A multicenter prospective series (42 patients from 22 hospitals) yielded 20 years of follow-up of patients with RRP and HPV typing who were treated with IFN-α in doses of 3 MU/m2 3 times per week. Results: During long-term follow-up (mean ± SD, 172 ± 36.8 months), the rate of event-free survival evaluated by Kaplan-Meier analysis was 42.8%, and the overall survival rate was 82.6%. The HPV typing revealed an association of HPV 11 with a more aggressive disease cour…
Immunization Campaigns and Strategies against Human Papillomavirus in Italy: The Results of a Survey to Regional and Local Health Units Representativ…
2019
Objective. The study aimed to assess the impact of HPV immunization campaigns organizational aspects, the characteristics of immunization program (vaccination targets and type of offer), and communicative strategies adopted by four Italian administrative regions on vaccination coverage observed. Methods. From November 2017 to March 2018, regional and Local Health Units (LHUs) representatives were invited to complete an online survey including 54 questions evaluating vaccination invite systems, access systems to vaccination centres, reminder and recall systems, and adverse events surveillance. An overall descriptive analysis was conducted. Since observed vaccine coverage (VC) obtained in fem…
Determinants of high-grade anal intraepithelial lesions in HIV-positive MSM.
2018
Objective - To assess determinants for histologically proven high-grade anal intraepithelial lesions (hHSIL) in HIV-positive men who have sex with men (MSM), a population at high-risk of HPV-related anal cancer. Design - APACHES is a prospective study of anal HPV and related-lesions in 513 HIV-positive MSM aged at least 35 years in six centres across France. Methods - At baseline, participants underwent high-resolution anoscopy (HRA) with biopsy of suspicious lesions, preceded by anal swabs for liquid-based cytology, p16/Ki67 immunostaining, and HPV DNA. hHSIL diagnosis was established by histopathological review panel consensus, and determinants assessed by logistic regression. Results - B…
