Dose-dependent expression of CLIP2 in post-Chernobyl papillary thyroid carcinomas
2015
Summary This study showed a clear dose-response relationship for the CLIP2 radiation marker in post-Chernobyl papillary thyroid carcinoma cohorts for young patients and hints to different molecular mechanisms in tumors induced at low doses compared to moderate/high doses.
Proliferative verrucous vs conventional leukoplakia: no significantly increased risk of HPV infection
2004
Proliferative verrucous leukoplakia (PVL) is a very aggressive form of oral leukoplakia (OL) with high morbidity and mortality rates, hypothesised to be linked to HPV infection. This study aimed to determine the presence of HPV DNA in PVL in comparison with OL, and in relation to social-demographical variables (age, gender, smoking and drinking habits) in an Italian multi-centric hospital-based study. The study group consisted of 58 cases of PVL and 90 cases of OL as controls (47 homogeneous (H) and 43 non-homogeneous (non-H) form), both recruited from four Italian cohorts. HPV DNA was identified in exfoliated mucosal cells by nested PCR (nPCR) with MY09/MY11 and GP5+/GP6+ primer pairs and …
Abnormal Immunoexpression of Cell Adhesion Molecules (CAMs) in Cervical Cancer
2010
Artículo publicado en: International Journal of Surgical Pathology published online 18 July 2010 The purpose of this study was to examine the immunoexpression of cell adhesion molecules (CAMs) E-cadherin, CD44s, and CD44v3 in cervical cancer and compare it with that in benign exo-endocervical tissue. In all, 81 cervical cancer biopsy specimens and 22 benign controls were included. Primary monoclonal antibodies NHC-38, F10-44-2, and 3G5 for E-cadherin, CD44s, and CD44v3 were used, respectively. Statistical significance was evaluated by the ?2 test. Antigen expression was significantly different in cervical cancer specimens compared with controls, showing marked decrease in membrane expressio…
Papillary squamous cell carcinoma of the oropharynx.
2003
A case of papillary squamous cell carcinoma of the oropharynx is reported. The lesion was located in the base of the tongue and grossly presented a characteristic finger-like pattern of growth. The clinicopathological profile of the neoplasm is presented and the differential diagnosis with other exophytic squamous cell carcinomas is discussed.
Cervical Cancer Screening in Women With Severe Mental Disorders An Approach to the Spanish Context
2018
Background The incidence of invasive cervical cancer and its mortality have been reduced through primary and secondary prevention. Screening rates tend to be lower in vulnerable groups, such as people with severe mental disorders, who have a later detection of cancer and a higher mortality. The access of these women to cervical cancer screening is uncertain in our context. Objective The aim of this study was to determine the cervical cancer screening rates in women with severe mental disorders. Methods This was a descriptive cross-sectional study. Women 25 to 65 years old who were admitted during 2016 to the psychiatric unit of a public hospital in Spain were included in the study, and it w…
Prospective seroepidemiologic study of human papillomavirus infection as a risk factor for invasive cervical cancer
1997
Background: Major risk factors for invasive cervical cancer include infection with human papillomavirus (HPV), infection with other sexually transmitted pathogens (e.g., Chlamydia trachomatis), and smoking. Since exposures to these risk factors can be related, the contribution of any single factor to cervical carcinogenesis has been difficult to assess. We conducted a prospective study to define the role of HPV infection in cervical carcinogenesis, with invasive cancer as an end point. Methods: A nested case‐control study within a joint cohort of 700 000 Nordic subjects was performed. The 182 women who developed invasive cervical cancer during a mean follow-up of 5 years were matched with 5…
Impact of a new carrageenan-based vaginal microbicide in a female population with genital HPV-infection: First experimental results
2019
OBJECTIVE: The objective of this study was to assess safety, satisfaction, and anti- viral effect of a new carrageenan-based vaginal microbicide in a population of fertile female patients with genital human papillomavirus (HPV) infection. PATIENTS AND METHODS: Forty healthy and sexually active women aged 18-45 years with genital HPV infection were enrolled. Each subject was treated with a gel formulated with 0.02% carrageenan and Propionibacterium extract (CGP) (Carvir, Depofarma SpA, Mogliano Veneto, Treviso, Italy). The subjects were evaluated at baseline, after the I cycle of therapy and after the II cycle. At final status, treatment acceptability and satisfaction were evaluated using a …
Immunohistochemical expression of ubiquitin and telomerase in cervical cancer
2009
Artículo publicado en: Virchows Arch (2009) 455:235–243. DOI 10.1007/s00428-009-0818-7 Ubiquitin and telomerase immunohistochemical expression patterns in cervical cancer were compared with normal cervical tissue samples. Eighty-one cervical cancer cases and 22 normal exo–endocervical tissue were examined with polyclonal antibody for ubiquitin and 44G12 clone for telomerase using tissue microarrays. The results were interpreted using a semiquantitative scale The average age of patients was 50.67 years. The most frequent histological types were moderately differentiated epidermoid carcinoma (43.5%), according to the degree of differentiation, and endocervical adenocarcinoma (42.1%). Immunohi…
Vaginal-assisted laparoscopic radical hysterectomy: rationale, technique, results.
2012
The authors conclude that vaginal-assisted laparoscopic radical hysterectomy is an oncologic viable alternative to abdominal radical hysterectomy, laparoscopic-assisted radical vaginal hysterectomy, totally laparoscopic radical hysterectomy, and robotic radical hysterectomy.
Refractory Acne and 21-Hydroxylase Deficiency in a Selected Group of Female Patients.
2009
<i>Background:</i> Excessive androgen production, suspected in women when acne is accompanied by hirsutism and menstrual irregularities, may be due to congenital adrenal hyperplasia. This inherited disorder of cortisol biosynthesis is caused in more than 90–95% of all cases by 21-hydroxylase deficiency (21-OHD). The steroid 21-hydroxylase gene <i>(CYP21)</i> has a high degree of variability. <i>Objective:</i> This study was conducted to evaluate <i>CYP21 </i>gene mutations in a selected group of women with papulopustular and comedonal acne refractory to treatment, irregular menses and hirsutism. <i>Methods:</i> 30 out of 61 women e…
