    The aim of this study was to determine the correlation between expression of HPV16 E6, p53 and p21 proteins and the physical state of HPV16 in cervical cytologies without squamous intraepithelial lesions (Non-SIL) and with low grade squamous intraepithelial lesions (LSIL), both with HPV16 infection. 101 liquid-based cytological samples were analyzed. 50 samples were without squamous intraepithelial lesions (Non-IL) and 51 samples of low grade squamous intraepithelial lesions (LSIL), both with HPV16 infection. HPV16 infection was determined by PCR-RFLP, and the physical state of HPV16 by in situ hybridization with tyramide-amplification. The expression of E6, p53 and p21 proteins was evaluated by immunocytochemistry. The expression of HPV16 E6 protein was significantly higher in LSIL that in Non-SIL samples (p=0.006). We found a significant correlation between E6 expression and the physical state of HPV16 in Non-SIL (p=0.049). Our results suggest that high expression of E6 in LSIL is an early event of cervical carcinogenesis and perhaps can be used as an early marker.

    An opera singer, who "made her living with her diaphragm", developed a post-traumatic unilateral radiculopathy due to cervical disc lesions, C3 to C6. During one year of severe neck and left arm pain she gradually lost the ability to sing difficult operatic passages which brought an end to her music career. Following a three level anterior cervical decompression and fusion, the neck and arm pain was immediately relieved. One week later her voice and singing ability returned to its full strength and power permitting her to resume her activities as a vocalist. The diagnosis of paresis of the left hemi-diaphragm as part of the cervical disc syndrome was implied by postoperative retrospective inference.

    Cervical precancerous lesions represented by cervical intraepithelial neoplasia (CIN) and cervical glandular intraepithelial neoplasia may progress to invasive cancer. The principle treatment of CIN is eradication of the transformation zone. However, all eradication methods are associated with some adverse events, particularly with perinatal consequences. It is therefore necessary to identify which women have CIN that has a low risk of transformation into invasive cancer. The presence of modifying factors can help to stratify CIN lesions according to their malignant potential. The evaluation of HPV genotype in particular holds great promise for defining patients at greater risk. Tailoring treatment to the individual patient is going to become a major consideration in the management of cervical precancerous lesions.

    Cervical cancer is one of the first causes of death in Mexican women population. The plasma proteome has a wide dynamic range concentrations of different protein and their alterations reflect the physiological state of the individual's health. The aim of this study was to characterize the 2D-PAGE serum patterns from healthy women and with different levels of cervical lesions. Changes in haptoglobin, apolipoproteins, and transthyretin, when comparing the serum from healthy women and serum from patients with different levels of cervical lesion were found. The Western blot analysis showed increasing concentrations of metalloproteinases (MMP's), proteins with important biological roles in tumor development and metastasis. Protein profiles in conjunction with MS, bioinformatics, and Western blot analysis, allow us to compile information for the acquisition of results to proposed candidates biomarkers of cervical cancer among Mexican women population.

    The screening results were reported based on the Fourier transform infrared spectroscopy (FTIR) analysis of the samples of exfoliated cervical cells from 354 women. Their spectra can be sorted into two types based on the emerging or not of the absorption bands near 970 cm-1 and 1 170 cm-1: T1 (83.1%) type without emerging, and T2 (16.9%) type with obviously emerging. All of the samples assigned to T1 were cytologically diagnosed as normal or within normal limits (PapⅠ). 28.9% and 71.1% of samples exhibiting T2 profile, were cytologically evaluated as Pap Ⅰand abnormal respectively. 3 women in the abnormal group were diagnosed as to have cervical cells with changes associated with high grade of inflammation, cervical scar and cervical erosion. Furthermore, based on the progressive change of the relative intensities of the absorption bands, both T1 and T2 profiles can be categorized into 6 subtypes. The observed heterogeneous spectra and the progressive changes in the absorption frequencies and the relative intensities exhibit features suggestive of the progressive process of cervical lesion. The FTIR method has the potential to complement the cytological smear for large-volume screening of cervical lesions.

    Sialylated oligosaccharides of glycoproteins and glycolipids have been implicated in tumour progression and metastases. Altered expression of glycosidic antigens has been reported in cervical cancer. In cervix premalignant lesions, an increased expression of sialic acid has been reported. In the present study we determined the expression profiles of the glycosidic antigens Tn, sialyl Tn (sTn), Lewis a (Lea), sialyl Lewis a (sLea), Lewis x (Lex) and sialyl Lewis x (sLex) in cervical scrapes with cytological diagnoses of normal, low-grade squamous intraepithelial lesions (LGSIL) and high-grade squamous intraepithelial lesions (HGSIL). Cervical scrapings were collected to detect tumour antigens expressions by flow cytometry using monoclonal antibodies. Cytometry analysis of Tn, sTn, Lea and Lex did not reveal differences at the expression level among groups. The number of positive cells to sLea antigen increased in the HGSIL group with respect to the normal group (=0.0495). The number of positive cells to sLex antigen in the samples increased with respect to the grade of squamous intraepithelial lesion (SIL) ( < 0.001, Mann–Whitney U test). The intensity of expression of this antigen increased in the HGSIL samples with respect to normal samples ( < 0.0068). sLex antigen could be a candidate to be used as biomarker for the early diagnosis of cervical cancer.

    Full Text Available Abstract Background The female lower genital tract is a gateway for pathogens entering the host through the mucous membrane. One of the prevalent human viruses is Torque teno virus (TTV. The major reported routes of TTV transmission are fecal-oral and parenteral. Furthermore, other modes of transmission, e.g. sexual contact, are suggested. To investigate the sexual route of TTV transmission, cervical smears of healthy women and those with cervical lesions were screened for the presence of TTV DNA. Methods TTV DNA was studied in cervical smears of 95 patients with cervical lesions and 55 healthy women. Paired serum samples were available from 55 and 42 women, respectively. All healthy women had normal cytology while 44 patients had histologically confirmed low-grade lesion (LGL and 51 high-grade lesion (HGL. TTV DNA was detected with primers specific for the non-coding region. In 40 paired cervical smears and serum samples, the phylogenetic group of TTV isolates was determined. The presence of HPV DNA in cervical smears was detected by means of PCR with MY09/11 primers. Results The prevalence of TTV DNA in cervical smears of healthy women was 52.7% and was comparable with that in paired serum samples (50%. Symptomatic women had significantly higher prevalence of TTV DNA in cervical smears (74.7% than healthy controls. The TTV DNA prevalence in patient serum samples was 51%. The phylogenetic groups of TTV serum isolates were concordant with those of TTV from cervical smears of the same subjects. In cervical smears, a wider variety of TTV isolates was found. The viral loads in cervical smears were 10 to 1000 times as high as in sera. The HPV-positive study subjects had significantly higher TTV DNA prevalence than HPV negatives. The prevalence of TTV was not associated with disease severity. Conclusion High prevalence of TTV in cervical smears suggests that sexual transmission is another mode of expansion of TTV infection among the population. The

    Background Non carious cervical lesions associated to muscle hyperfunctions are increasing. Microhybrid resin composites are used to restore cervical abfractions. The purpose of this study was to investigate if resin composites modify tooth plaque, inducing an increment of cariogenic microflora and evaluate their effect, in vivo and in vitro, against S. mutans. Material and Methods Eight abfractions were restored with two microhybrid resin composites (Venus, Heraeus-Kulzer® and Esthet-X, Dentsply®), after gnatological therapy, in three patients with muscle hyperfunctions. For each abfraction three samples of plaque were taken from the cervical perimeter: before the restoration, one week and three months after restoration. The samples were evaluated both by traditional microbiological methods and by Polymerase Chain Reaction (PCR). In vitro, disk-shaped specimens of the two composites were prepared to estimate the effects against pre-cultured S. mutans, after incubation at 37°C for 24h and assessed by a turbidimetric technique. Results In vivo no differences were found in plaque growth, for all samples, before and after restoration with both composites; in vitro, instead, a significant reduction of S. mutans growth was found between specimens of two composites (Mann-Whitney U-test p>0,06). Conclusions In this study a relevant consideration was elicited: composite materials, in vivo, do not modify plaque composition of non carious cervical lesions to a potential cariogenic plaque.

    Full Text Available Cervical cancer is the second most common gynecological malignancy in the world. Human papilloma virus (HPV infection is the leading ethiologic agent in the development of premalignant and malignant cervical diseases. HPV is a member of the Papovaviridae family and until now over 100 types have been recognized. There are two types of viral infection: latent and productive. Virus induced oncogenesis is the result of interaction between virus oncoproteins E6 and E7 and tumor supresor host genes p53 and Rb. Many cofactors such as immunosuppression, early sexual relationship, multiple sexual partners, other sexualy transsmited infections and smooking are contributing factors of the precancerous and invasive cervical lesions. According to the oncogenic potential HPV are divided into three groups: low, intermediate and high oncogenic risk viruses. Molecular technics which are used for the virus detection are: In situ hibridisation,, Hybrid capture test and polymerasa chain reaction. Human papilloma virus testing has an important role in the follow up and treatment of women with 'atypical squamous cells of unknown significant' changes in cervical smears and low-grade squamous intraepithelial lesions, changes in punch biopsy.

    The metalloproteinases (MMP) 11 and 12 have been shown to be expressed in cervical cancer (CC). In order to extend our previous results, these MMPs were evaluated in cervical precursor lesions. One hundred seventeen cervical scrapes: thirty-six normal, thirty-six low grade squamous lesions (LSIL), thirty-six high grade (HSIL), nine CC; and, also ninety-nine paraffin-embedded cervical lesions: fifteen normal cervices, thirty eight LSIL, sixteen HSIL, and five CC were collected. The samples were analyzed for relative expression by real time RT-PCR or immunohistochemistry assay. We were able to identify a relative increased expression of MMP11 in 75% and 78% from LSIL and HSIL samples, respectively. While MMP12 expression was 64% and 75% in LSIL and HSIL, respectively. Positive samples for MMP11 expression were also positive for MMP12 expression and also increased according to illness progression. In the tissues, MMP11 or MMP12 expression was observed in the cytoplasm of the neoplastic cells, while in the normal epithelium was absent. The reaction was always stronger for MMP12 than MMP11. MMP11 expression was present in 77% and 66% of LSIL and HSIL, while MMP12 expression was 73% and 68%. There was a relationship between MMP11 or MMP12 expression and HPV infection. Our data are showing a relationship between diagnostic of precursor lesions and the MMP11 and 12 expressions, suggesting that their expression could be an early event in the neoplastic lesions of the cervix and could have clinical significance.

    Full Text Available Background: The sensitivity of cervical cytology for detection of glandular lesions is reported to be low. We conducted this study to assess the diagnostic accuracy of cervical Papanicolaou (Pap smears for uterine glandular lesions and to compare the diagnostic utility of conventional and liquid-based cytology (LBC smears for glandular lesions. Materials and Methods: Archived histopathology records of all cases reported as endocervical and endometrial adenocarcinoma in the study period were identified and the available corresponding Pap smears (in preceding 1 year were retrieved. In addition, the Pap smears reported as glandular cell abnormalities (GCA during the same study period were retrieved. The overall prevalence of GCA, sensitivity, and specificity of Pap smears for the detection of GCA was calculated. The diagnostic accuracy of conventional and LBC smears for the diagnosis of GCA was also compared. Results: The prevalence of GCA in our study was 0.32%. The overall specificity of Pap smears for the diagnosis of GCA was 60.8%, this was not significantly different between conventional and LBC smears (P = 0.4. The overall sensitivity of Pap smears for the detection of GCA was 41.8%; LBC smears had significantly better sensitivity as compared to conventional smears for the detection of endometrial as compared to endocervical adenocarcinoma (P < 0.05. Conclusions: The prevalence of GCA in Pap smears is low. The specificity of Pap smears, for diagnosis of GCA, was found to be moderate. However, the overall sensitivity of Pap smears for the detection of GCA was low, though better for LBC as compared to conventional smears.

    Fernanda Rangel da Veiga

    Full Text Available CONTEXT AND OBJECTIVE: Cervical cancer is a serious public health problem in Brazil. For patients with unsatisfactory colposcopic examinations without visible lesions, but with cervical cytological tests suggesting high-grade squamous intraepithelial lesion (HSIL, the national recommendation is to repeat cervical cytological tests after three months. Our aim was to assess the prevalence of HSIL and cancer among patients with initial cervical cytological tests suggestive of HSIL but with unsatisfactory colposcopic examinations without visible lesions, in order to contribute towards the discussion regarding a more effective clinical approach that might diminish the likelihood of patient abandonment of follow-up before appropriate diagnosis and treatment. DESIGN AND SETTING: Cross-sectional study in Colposcopy Clinic of IFF/Fiocruz. METHOD: Patients admitted between December 1989 and April 2007 with cytological diagnoses of HSIL but with unsatisfactory colposcopic examinations without visible lesions underwent cervical cone biopsy. RESULTS: Sixty-five such patients were included, comprising 33.8% with HSIL and 4.6% with cancer, confirmed histologically. The other patients presented low-grade squamous intraepithelial lesion (26.1%, glandular dysplasia (1.5% and absence of disease (33.8%. CONCLUSION: The observed prevalence of cancer and HSIL does not seem to be enough to justify immediate referral for cone biopsies to investigate the cervical canal in these cases. The findings suggest that the recommendation of repeated cytological tests following an initial one with HSIL, among patients with unsatisfactory colposcopic examinations without visible lesions, is appropriate in our setting. Efforts are needed to ensure adherence to follow-up protocols in order to reduce the chances of losses.

    OBJECTIVE To analyze the relation ship among vulva condyloma acuminatum, high-risk human papillomavirus (HPV) infections and cervical epithelium lesions.METHODS From May 2002 to April 2004 patients with vulva condyloma acuminatum were examined employing vulva biospy, colposcopy, highrisk HPV-DNA test and cervical bioscopy.RESUTS In 418 cases of vulva condyloma acuminatum, verified by pathologic analysis, high-risk HPV (+) infections were detected in 68.7% (287/418) of the cases. Among those patients, 20.6% (59/287) had concurrent subclinical cervical intraepithelial neoplastic (CIN) lesions. Among the high-risk HPV(-) 31.3 % (131), patients 7.6% (10/131) had concurrent subclinical CIN lesions. Pathological examination results: cervicitis,167 (40.0%); cervical HPV infection, 182 (43.5%); CIN-Ⅰ, 51(12.2%); CIN-Ⅱ, 16 (3.83%); CIN-Ⅲ, 2 (0.5%); cervical cancer, none. Another patient had vulva condyloma acuminatum with valva intraepithelial neoplasia (VIN) Ⅱ~Ⅲ.CONCLUSION It was concluded that simultaneous cervical HPV infection of many types was rather common in patients with vulva condyloma acuminatum. Vulva condyloma acuminatum is the chief clinical symptom which hints at a high possibility of infection with high-risk HPV. The patients are at high-risk for CIN and cervical cancer. We must pay more attention to the cervix in cases with vulva condyloma acuminatum.

    Full Text Available Glass ionomer based materials are clinically popular in several areas of restorative dentistry, but restoration of cervical lesions has proven particularly successful. Various etiologies, conformations, locations and structural characteristics make non-carious cervical lesions more challenging to adhesive restorative procedures and marginal seal in the long run. Due to their characteristics, glass ionomer cements (GICs have precise indication for these cases. Moreover, the use of a GIC base underneath composite resin, the so-called "sandwich" or mixed technique, allows associating the good characteristics of composite resins and GICs, and has been considered quite useful in the restoration of non-carious cervical defects. The aim of this paper is to critically review the literature and discuss peculiar features of GICs regarding their role in the restoration of non-carious cervical lesions.

    Cervical cancer is about 6 times more frequent in Ecuador than in Japan. We investigated the association between infection by the human papillomavirus (HPV) and the genesis of cervical cancer in specimens of lesions of the cervical epithelium obtained from patients in Ecuador and Japan. We also examined the results of HPV DNA detection and typing by the polymerase chain reaction (PCR) performed under the same technical conditions in areas with differing rates of cervical cancer. Purified tissue DNA from paraffin-embedded samples was amplified by PCR with universal and type-specific primers. HPV DNA was detected in 8 (20%) of 40 normal cervical epithelial samples from Ecuadorian patients, 19 (45%) of 42 low-grade squamous intraepithelial lesions (LSIL), 16 (50%) of 32 high-grade squamous intraepithelial lesions (HSIL), and 38 (81%) of 47 invasive squamous cell carcinomas (SCC) compared with 3 (10%) of 30 normal cervical specimens from Japanese patients, 107 (51%) of 210 HSILs, and 45 (71%) of 63 SCCs. The prevalence of HPV types 16 and 18 rose significantly with increasing histological grade (p poverty and underdevelopment may influence the prevalence of HPV infection and the sequence of events after HPV infection culminating in cervical cancer. These factors may help to explain the differing geographic distribution of this disease.

High risk HPV infection is essential for cervical cancer development so HPV testing is a new tool used for screening patients for cervical neoplasia. HPV testing was proven most useful for women over 30 years old, in cases in which cytology identified ASC-US and after treatment for CIN. This article outlines the clinical significance of HPV-DNA tes...

    The value of computed tomography in the spine and spinal cord disease recently has been well documented. However, little attention is made to the role of computed tomography in foramen magnum and high cervical cord lesion. We report 16 cases of the foramen magnum and high cervical cord lesion. Method: Either EMI Head Scanner, CT 1010 (slice thickness 10 mm) or EMI Whole Body Scanner, CT 5005 (slice thickness 13 mm) was used. In 9 cases enhanced CT with intravenous injection of contrast medium was performed. Eleven cases received intrathecal injection of metrizamide. Materials: 1) control group without cervical pathology 70 cases, 2) spinal cord tumor 6 cases, 3) atlanto-axial dislocation 6 cases, 4) Chiari malformation (type 1) 3 cases, 5) spinal foreign body (acupuncture needle) 1 case. Results: 1. plain CT. 1) In control group without cervical pathology the cervical cord at C/sub 1/ level was seen as area surrounded by ring of subarachnoid space. 2) In 14 cases except for 1 case of atlanto-axial dislocation and 1 case of spinal foreign body identification of the cervical cord at C/sub 1/ level was impossible. 3) CT was of diagnostic value in detecting altanto-axial dislocation and spinal foreign body. 2. enhanded CT. Meningioma and neurinoma showed positive contrast enhancement. However, astrocytoma and herniated cerebellar tonsils were not detectable. 3. CT metrizamide myelography visualized the subarachnoid space and made it possible to localize the lesion in the spinal canal in relation to the spinal cord. Conclusion: Attention should be given to plain CT finding at C/sub 1/ level in diagnosis of foramen magnum and high cervical cord lesion. If identification of cervical cord at C/sub 1/ level is impossible, it is suspected that subarachnoid space is blocked by the lesion, and enhanced CT and CT metrizamide myelography must be performed.

    Full Text Available Objective  To explore the association between high-risk human papillomavirus (HR-HPV viral load and pathological grades of cervical intraepithelial neoplasia (CIN and cervical cancer. Methods  A total of 1248 patients from General Hospital of PLA, who underwent colposcopy and surgery due to cervical lesions between Jan. 2006 and Aug. 2011 were enrolled in this study, and they were divided five groups: cervicitis, CIN Ⅰ, CIN Ⅱ-Ⅲ, stage Ⅰ cervical cancer and stage Ⅱ cervical cancer. HR-HPV viral load (RLU/CO was determined by the Hybrid Capture Ⅱ (HCⅡ system, and they were categorized into five groups: 0-0.99, 1.00-9.99, 10.00-99.99, 100.00-999.99, ≥1000.00. The mean value and standard deviation of different HR-HPV viral load in the patients with cervicitis or with CIN Ⅰ, CINⅡ-Ⅲ, stage Ⅰ cervical cancer or stage Ⅱ cervical cancer were compared, and the correlation of HR-HPV viral load and pathogenesis of cervical lesions was analyzed. Results  HPV viral loads were significantly higher in CINⅠ(842.1±983.9, CINⅡ-Ⅲ (690.1±795.0, stage Ⅰ cervical cancer (893.1±974.2 and stage Ⅱ cervical cancer (699.5±908.3 patients than in cervicitis patients (274.2±613.6, P < 0.05, and the HPV viral loads in CINⅠ(842.1±983.9 and stage Ⅰ cervical cancer patients were higher than those in CINⅡ-Ⅲ patients (P < 0.05. When HR-HPV viral load was ≥100RLU/CO, the risk of CIN and cervical cancer increased with the increase in viral load, but there was no correlation between the viral load and pathological grades of cervical lesions. In the patients with stage ⅠB-Ⅱ cervical squamous cell carcinoma, when the HR-HPV viral load was ≥100RLU/CO, the risk of lymph node metastasis increased (P < 0.05, and the number of patients with maximum diameter of the cervical tumor ≥4cm also increased (P < 0.05. However, the HR-HPV viral load was not correlated with patient age, pathological type of the lesion, depth of cancer

    To predict the impact of current vaccines on cervical cancer and for the improvement of screening programs, regional data on distribution of human papillomavirus (HPV) types in women with or without cervical cancer is crucial. The present meta-analysis intend to comprehensively evaluate the HPV burden in women with invasive cervical cancer, high-grade squamous intraepithelial lesion (cervical intraepithelial neoplasia 2 and 3), low-grade squamous intraepithelial lesion (cervical intraepithelial neoplasia 1), atypical squamous cells of undetermined significance and normal cytology, as these data will help decision making in regards with screening programs and HPV vaccination in Iran. To determine the HPV prevalence and type distribution in Iranian women with or without cervical cancer, 20 published studies were included in this meta-analysis. In total, 713, 124, 104, 60, and 2577 women invasive cervical cancer, high-grade squamous intraepithelial lesion (cervical intraepithelial neoplasia 2 and 3), low-grade squamous intraepithelial lesion (cervical intraepithelial neoplasia 1), atypical squamous cells of undetermined significance and normal were reviewed, respectively. Overall HPV prevalence in women with invasive cervical cancer, high-grade squamous intraepithelial lesion (cervical intraepithelial neoplasia 2 and 3), low-grade squamous intraepithelial lesion (cervical intraepithelial neoplasia 1), atypical squamous cells of undetermined significance and normal cytology were 77.4%, 71.8%, 65.3%, 61.7%, and 8.4%, respectively. The six most common types were HPV 16, 18, 6/11, 31, and 33; among them HPV 16 was the most frequent type in all five different groups. According to this study, it was estimated that HPV vaccines could have a great impact on prevention of cervical cancer in Iran. In conclusion, this meta-analysis highlights the necessity of introducing vaccination program in Iran.

    Only a small proportion of women infected with Human Papillomavirus (HPV) develop cervical cancer. Host immune response seems to play a role eliminating the viral infection and preventing progression to cancer. Characterization of tumor infiltrating lymphocytes (TILs) in cervical pre-neoplastic lesions and cervical cancer may be helpful to understand the mechanisms that mediate this protection. The aim of this study was to determine if there are differences in the localization and density (cells/mm(2)) of CD8+ T-cells, CD4+ T-cells and Tregs (CD25 + Foxp3+) in cervical pre-neoplastic lesions and cervical cancer. Immunohistochemical analysis of sections of 96 (26 CIN1, 21 CIN2, 25 CIN3, and 24 SCC) samples revealed that regardless of CIN grades, CD8+ T-cells are more abundant than CD4+, CD25+ and Foxp3+ cells in both the stroma and epithelium. There was a higher density of CD8+ cells in the stroma of cervical cancer compared to CIN3 (OR = 4.20, 95% CI 1.2-15), CIN2 (OR = 7.86, 95% CI 1.7-36.4) and CIN1 (OR = 4.25, 95% CI 1.1-17). Studies evaluating whether these cells are recruited before or after cancer progression will be helpful to understand the role of these cells in the natural history of HPV-induced lesions.

    Full Text Available Introduction. High-risk human papilloma viruses play a main role in the development of cervical dysplasias and carcinomas. p16INK4a can be considered as a surrogate marker of active highrisk human papillomaviruses infection in dysplastic and neoplastic cells of the cervix. This study was aimed at determining the presence and level of p16INK4a expression in inflammatory, preneoplastic and neoplastic lesions of the cervix. Material and Methods. The study was performed on 109 samples of cervical biopsy. Cervical cancer was diagnosed in 36 patients, 34 patients had a preneoplastic change (dysplasia in stratified squamous cervix epithelium and a nonspecific inflammatory process was found in 39 patients. In all samples, immunohistochemical analysis using antibodies to p16INK4a was performed. Results. The expression of p16INK4a was verified in all cases of cervical cancer (100%, in 67.65% of dysplastic cervical lesions and in 38.5% of inflammatory lesions. A statistically highly significant difference was found in the presence and level of expression among neoplasic, dysplastic and inflammatory lesions of the cervix (χ² = 76.02, p < 0.001. The expression was more frequent and had a higher level in neoplastic and high grade dysplastic lesions compared to expression in inflammatory lesions and low grade dysplasias. Conclusion. The analysis of the presence of p16INK4a can differentiate non-neoplastic, high grade preneoplastic and neoplastic changes of the cervix. The use of p16INK4a in interpreting borderline lesions of the cervix can enable a rational therapeutic treatment of patients.

    OBJECTIVE To investigate the available parameters in gynecological screening for cervical lesions by liquid-based cytology technology (ThinPrep Cytology Test, TCT) and The Bethesda System (TBS), also with computer image analysis. METHODS With application of the image analysis system, all grades of cervical lesion cells were detected quantitatively and sorted in atypical squamous cells of undetermined significance (ASCUS), atypical squamous cells-cannot exclude HSIL (ASC-H), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL) and cervical squamous cell carcinoma (SCC) with the mean optical density (MOD), average grey (AG), positive units (PU), and nucleus to cytoplasmic ratio (N:C). Differences between each group of cells were compared and analyzed statistically.RESULTS Apart from four stereologic parameters in LSIL and HSIL groups there were no differences among them, in the other groups, there was statistically significant in differences between MOD, AG and PU values. Differences between them in the ratio of nucleus to cytoplasm were highly statistically signifi cant. CONCLUSION Stereological indexes may serve as a screening tool for cervical lesions. The image analysis system is expected to become a new means of cytological assisted diagnosis.

    Full Text Available A hundred-sixty paraffin-embedded specimens from female cervical lesions were examined for human papillomavirus (HPV types 6, 11, 16 and 18 infections by non-isotopic in situ hybridization. The data were compared with histologic diagnosis. Eighty-eight (55 biopsies contained HPV DNA sequences. In low grade cervical intraepithelial neoplasias (CIN I, HPV infection was detected in 78.7 of the cases, the benign HPV 6 was the most prevalent type. HPV DNA was detected in 58 of CIN II and CIN III cases and in 41.8 of squamous cell carcinomas (SCC. Histologically normal women presented 20 of HPV infection. Oncogenic HPV was found in 10 of these cases, what may indicate a higher risk of developing CINs and cancer. Twenty-five percent of the infected tissues contained mixed infections. HPV 16 was the most common type infecting the cervix and its prevalence raised significantly with the severity of the lesions, pointing its role in cancer pathogenesis. White women presented twice the cervical lesions of mulatto and African origin women, although HPV infection rates were nearly the same for the three groups (approximately 50. Our results showed that HPV typing by in situ hybridization is a useful tool for distinguishing between low and high risk cervical lesions. Further studies are required to elucidate risk factors associated with HPV infection and progression to malignancy in Brazilian population.

    Full Text Available Introduction. The restoration of non-carious cervical lesions is specific, mostly because of the location of their margins, especially the cervical margin, which is determined in cement and/or dentine. This feature makes the cervical margin more susceptible to micro-leak­age, causing marginal discoloration, postoperative sensitivity, development of the secondary caries and loss of the restoration. Material and methods. One of the criteria for inclusion of a patient in this study was the presence of at least two non-carious cervical lesions to be restored with the minimum depth of 1mm, independently of their location in the dental arch. A total of 60 restorations were placed in 30 patients, and every patient received both tested materials (composite resins and compomer on their non-carious cervical lesions. The clinical evaluation of the therapeutic success was performed six months and then one year after the day of the placement of restorations using the modified-United States Public Health Service criteria. The following was evaluated: retention, marginal integrity, marginal discoloration, wear, postoperative sensitivity and secondary caries. Results. A statistically significant high percent of restorations/teeth with postoperative sensitivity was found in the group of resin composite restorations after six months. At the end of the evaluation period, that is after one year, there were no statistically significant differences between materials for all evaluated criteria. Conclusion. The results of this study show the identical quality of both examined materials one year after the readjustment of non-carious cervical lesions.

    The purpose of our report is to describe a new application of kyphoplasty, the percutaneous anterolateral balloon kyphoplasty that we performed in two cases of metastatic osteolytic lesions in cervical spine. The first patient, aged 48 years, with primary malignancy in lungs had two metastatic lesions in C2 and C6 vertebrae. Patient's complaints were about pain and restriction of movements (due to the pain) in the cervical spine. The second patient, aged 70 years, with primary malignancy in stomach, had multiple metastatic lesions in thoracolumbar spine and C3, C4 and C5 vertebrae without neurological symptoms. The main symptoms were from cervical spine with severe pain even in bed rest and systematic use of opiate-base analgesic. The preoperative status was evaluated with X-rays, CT scan, MRI scan and with Karnofsky score and visual analogue pain (VAS) scale. Both patients underwent percutaneous anterolateral balloon kyphoplasty via the anterolateral approach in cervical spine under general anaesthesia. No clinical complications occurred during or after the procedure. Both patients experienced pain relief immediately after balloon kyphoplasty and during the following days. The stiffness also resolved rapidly and cervical collars were removed. VAS score significantly improved from 85 and 95 preoperatively to 30 in both patients. Karnofsky score showed also improvement from 40 and 30 preoperatively to 80 and 70, respectively, at the final follow-up (7 months after the procedure). Fluoroscopy-guided percutaneous anterolateral balloon kyphoplasty proved to be safe and effective minimally invasive procedure for metastatic osteolytic lesions of the cervical spine, reducing pain and avoiding vertebral collapse. Experience and attention are necessary in order to avoid complications.

    The relation between eight specific colposcopic diagnostic findings and the histologic grade of a cervical lesion in 896 women was evaluated. The size of the transformation zone (TZ), the size of the lesion, the intensity of the color tone, distinct margins, the pathology of the vessels, and the presence of micropapillae as single findings were highly statistically correlated to the histologic grade (P < 0.0001). By logistic regression analysis the risk for a higher histologic grade when assessed by colposcopy was greatest in women with variation of the acetowhite color (odds ratio (OR) = 16.0; 95% CI, 10.0-26.0) followed by coarse vessels (OR = 10.0; CI, 3.2-34.0). Lesion-size larger than 50% of the visible cervix had an OR of 3.6 (CI, 2.1-6.3). Extention beyond TZ had an OR of 0.4 (CI, 0.2-0.4) and larger TZ had an OR of 0.5 (CI, 0.3-0.9). In conclusion we found that the size of the cervical lesion had some independent predictive value and should be considered in future trials.

    Human papillomavirus (HPV) regulation of host immune response leads to cervical lesions. In particular, natural killer (NK) cells are crucial for HPV control. Since specific HLA-I/KIR interactions modify NK cell activation, we analyzed HLA-C and KIR alleles in HPV infection and lesion development in 150 controls, 33 condyloma acuminatum, and 111 invasive cervical cancer (ICC) patients. We showed an increase in HLA-C1/KIR2DL2 and HLA-C1/KIR2DL3 pairs in HPV high-risk infected patients (OR 3.05, 3.24) with ICC (OR 1.33, 3.68). These data suggest HLA-C and KIR typing as risk marker for HPV infection and lesion evolution.

    Human papilloma virus (HPV) is considered as the main sexually transmitted etiological agent for the cause and progression of preneoplastic cervical lesions to cervical cancer. This study is discussing the prevalence of HPV and its genotypes in cervical lesions and invasive cervical cancer tissues and their association with various risk factors in women from Varanasi and its adjoining areas in India. A total of 122 cervical biopsy samples were collected from SS Hospital and Indian Railways Cancer Institute and Research Centre, Varanasi and were screened for HPV infection by PCR using primers from L1 consensus region of the viral genome. HPV positive samples were genotyped by type-specific PCR and sequencing. The association of different risk factors with HPV infection in various grades of cervical lesion was evaluated by chi-square test. A total of 10 different HPV genotypes were observed in women with cervicitis, CIN, invasive squamous cell cervical carcinoma and adenocarcinoma. Increased frequency of HPV infection with increasing lesion grade (p=0.002) was observed. HPV16 being the predominant type was found significantly associated with severity of the disease (p=0.03). Various socio- demographic factors other than HPV including high parity (p<0.0001), rural residential area (p<0.0001), elder age (p<0.0001), low socio-economic status (p<0.0001) and women in postmenopausal group (p<0.0001) were also observed to be associated with cervical cancer.These findings show HPV as a direct cause of cervical cancer suggesting urgent need of screening programs and HPV vaccination in women with low socio-economic status and those residing in rural areas.

    Full Text Available Background. Aneurysms of the extracranial vertebral artery are rare and can provide a diagnostic and therapeutic challenge. Methods. We reviewed the clinical history of a patient presenting with cervical radiculopathy, who harboured an extracranial vertebral artery aneurysm eroding the cervical spine. Results. CT Angiography and MR Angiography set the diagnosis, by revealing a left C5-C6 vertebral artery aneurysm with cervical root impingement. Bony reconstruction depicted enlargement of the C6 transverse foramen and a marked enlargement of the C6-C7 intravertebral foramen. The lesion was treated by intravascular proximal vertebral artery occlusion. Conclusions. Extracranial vertebral artery aneurysms require a high index of clinical suspicion. This is the first report of a vertebral artery pseudoaneurysm presenting with bony erosion, which supports a less minacious portrayal of vertebral artery aneurysms.

    Full Text Available Introduction: An important reason for higher cervical cancer incidence in developing countries is lack of effectivescreening programs like pap smear, aimed at detecting precancerous conditions before they progress to invasivecancer. The potential difficulties in implementing cervical cytology based screening in low-resource settings haveprompted the investigation of accuracy of alternative low technology tests such as Visual inspection with acetic acidapplication [VIA], Visual inspection with acetic acid application with magnification [VIAM], visual inspection onLugol’s Iodine application [VILI] in early detection of cervical neoplasia .In our study we compared pap smear withVIA to study the accurarcy of VIA as it is simpler and easier technique to be used as screening in low resourcesettings. Aim: This is a hospital based descriptive, prospective study to evaluate validity of pap smear and VIAtechniques as screening tests in identifying cervical lesions. Materials And Methods: After general and systemicexamination as a routine,visual local pelvic examination including visualisation of cervix and vagina per speculumand the findings are documented in the proforma .Then VIA and pap smear are done in that order, if any of thesetests are positive then cervical biopsy will be taken and further advise to the subject is given. Results: A total of 313women were involved in the study. The sensitivity of pap smear is 54.5% specificity is 98.9% while that of VIA95.4% and 97.9%respectively. We found that VIA accuracy was comparatively more than that of pap smear.Conclusion: In low resource settings, usefulness of VIA is more than that of pap smear. We suggest to perform VIAin all the women inspite of having pap smear facility to improve detection rate of cervical lesions and provide betterpatient councelling and treatment.

    Full Text Available An association between immune-mediated diseases and cervical pre-malignant and malignant lesions is described, having the human papillomavirus (HPV infection a causal role. Related studies have been generally focused on systemic lupus erythematosus (SLE patients, but relatively to other diseases, such as rheumatoid arthritis (RA, Sjögren's syndrome (SS and systemic sclerosis (SSc, data has not been systematically evaluated. We conducted a systematic review analysis of the literature in PubMed, including articles published until March of 2015, in patients with RA, SS, SLE and SSc, to evaluate the frequency of HPV infection, cervical dysplasia and cervical cancer, and associated factors, with particular interest on the role of glucocorticoids and immunosuppressive treatment. Moreover, safety and efficacy of HPV vaccines in these patients was investigated. Of 476 articles identified, 27 were finally included. The studies showed an increased prevalence of cervical dysplasia and cancer, with the HPV infection being an important associated factor, in particular in SLE patients. The data relatively to other rheumatic diseases was very scarse, but an increased prevalence of smear abnormalities was also found in RA. Patients exposed to glucocorticoids and to long-term immunosuppression, particularly cyclophosphamide, have increased risk of presenting more pre-malignant lesions than the general population. The available vaccines seem to be generally safe and immunogenic in the short- period evaluation, but long-term follow-up is required to evaluate the impact of the vaccine in the protection against HPV infection and occurrence of high-grade cervical lesions.

    Full Text Available Abstract Background Altered sialylation has been observed during oncogenic transformation. Sialylated oligosaccharides of glycoproteins and glycolipids have been implicated in tumor progression and metastases. In the cervical cancer high levels of sialic acid have been reported in the patients serum, and an increased of total sialic acid concentration has been reported for the cervical neoplasia and cervical cancer. This study investigates the changes in expression and distribution of α2,3-linked sialic acid and α2,6- linked sialic acid in low and high squamous intraepithelial lesions and in normal tissue. Methods Lectin histochemistry was used to examine the expression and distribution of sialic acid in different grades of cervical neoplasia. We applied Maackia amurensis lectin, which interacts with α2,3-linked sialic acid and Sambucus nigra lectin specific for α2,6-linked sialic acid. Results The histochemical analysis showed that α2,3-linked sialic acid and α2,6- linked sialic acid increased in intensity and distribution in concordance with the grade of squamous intraepithelial lesion (SIL. These results are in concordance with a previous study that reports increased RNAm levels of three sialyltransferases. Conclusions These results show that the change in sialylation occurs before cancer development and may play an important role in cellular transformation. These findings provide the basis for more detailed studies of the possible role of cell surface glycoconjugates bearing sialic acid in the cellular cervix transformation.

    Full Text Available Objective. To estimate the prevalence and genotypes of high-risk human papillomavirus (HPV focusing HPV 16, 18, 52, and 58 in Japan. Methods. Liquid-base cytology specimens were collected from Japanese women (n=11022, aged 14–98. After classifying cytodiagnosis, specimens were analyzed for HPV DNA by the multiplex polymerase chain reaction method, where 1195 specimens were positive for cervical smear, except adenomatous lesions. Result. HPV genotypes were detected in 9.5% of NILM and 72.2% of ASC-US or more cervical lesions. In positive cervical smears, HPV genotypes were HPV 52 at 26.6%, HPV 16 at 25.2%, HPV 58 at 21.8%, and HPV 18 at 7.1%. Most patients infected with HPV 16 were between 20–29 years old, decreasing with age thereafter. As for HPV 52 and 58, although the detection rate was high in 30- to 39-year-olds, it also was significant in the 50s and 60s age groups. Conclusion. In Japan, as a cause of abnormal cervical cytology, HPV52 and 58 are detected frequently in addition to HPV 16. In older age groups, HPV 52 and 58 detection rates were higher than that observed for HPV 16. After widespread current HPV vaccination, we still must be aware of HPV 52 and 58 infections.

    Full Text Available Introduction: considering the relationship between human papilomavirus and cervical cancer, the current increase in sexually transmitted diseases constitutes the biggest threaten to adolescents’ health. Objective: to characterize high-degree intraepithelial cervical lesion in adolescents and young women. Method: a descriptive and observational study was conducted. It included 52 patients, all of them younger than 24 years old, who had been diagnosed with high-degree cervical pathology and were treated in the cervix pathology consultation of the "Ramón González Coro" Teaching Gynecologic and Obstetric Hospital from January 2007 to December 2008. Risk factors and diagnosis variables were studied and processed using the SPSS 11.5 system for Windows, through the determination of absolute and relative frequencies. Results: 78,8 % of patients had from 20 to 24 years old, 65,3 % of them began having sexual relationships between 15 and 17 years old, 62,2 % had had 3 or more sexual partners and 67,3 % used no contraceptive method. Cyto- histological correlation was of 100 % for intraepithelial cervical lesion II and III. Conclusion: the results of the present study compromise us to highlight the need of extended sexual education among young people.

    Objective: To investigate the expression of aquaporin 1 in cervical squamous carcinomas (CSC) and cervical precancerous lesions, and the relationship between the tumor clinicopathological parameters, prognosis and the expression of AQP1. Methods: Immunohistochemical method (EliVision) was used to detect the expression of AQP1 in samples from 106 patients [20 with normal cervical tissue, 30 with cervical intraepithelial neoplasia (stage Ⅰ and Ⅱ) and 56 with CSC]. Survival analysis was performed by Kaplan-Meier method. Results: AQP1 protein was expressed in vascular endothelia of all samples. It showed upregulation of AQP1 expression in CSC. There was a significant difference between CSC and normal cervical tissues (P<0.05). AQP1 was expressed in some tumor cells and unexpressed in normal squamous epithelial cells. And APQ1-expressing tumor cells were positively related to lymph node metastasis. Patients with APQ1-expressing tumor cells had the lower survival rate than the ones without. Conclusion: Abnormal expression of AQP1 plays an important role in the development of CSC. Positive expression of AQP1 in tumor cells maybe enhances tumor metastasis and could be used as a marker for tumor prognosis.

    Full Text Available Abstract Background Cervical carcinoma remains the second leading cause of cancer death in women worldwide and sexual behavior is regarded as the main contributing factor. We studied cervical cytology screening with surgical biopsy follow-up in women prisoners and compared the findings to those in the general population. Methods We reviewed 1024 conventional cervical smears, 73 cervical biopsies and 2 loop electrosurgical excision procedure (LEEP specimens referred to us from the Correctional Center in Columbus, Ohio during a 12-month period. The results were compared to 40,993 Pap smears from the general population for the same 12-month period. Results High grade squamous intraepithelial lesion (HGSIL was diagnosed in 1.3% of the cervical smears from the inmate population versus 0.6% in the general population (p < 0.01. The unsatisfactory rate was 1.6% compared to 0.3% in the general population (p < 0.01. Among the study population, follow-up tissue diagnosis was obtained in 24.3% of the abnormal cytology results (ASCUS, LGSIL, and HGSIL. Of the HGSIL Pap smears, 61.5% had a subsequent tissue diagnosis. Thirty-nine biopsies (52% of the all inmate biopsies and LEEP showed CIN II/III (cervical intraepithelial neoplasia II/III. Eight of these thirty-nine follow-up biopsies diagnosed as CIN II/III had a previous cervical cytology diagnosis of ASCUS. The average age for HGSIL was 30.5 years (S.D. = 5.7 and for low grade squamous intraepithelial lesion (LGSIL was 27.2 years (S.D. = 6.1. Conclusion A significantly higher prevalence of HGSIL cervical cytology and unsatisfactory smears was encountered in female inmates, with tissue follow-up performed in less than two thirds of the patients with HGSIL. These results are in keeping with data available in the literature suggesting that the inmate population is high-risk and may be subject to less screening and tissue follow-up than the general population. Clinicians should proceed with urgency to improve

    Full Text Available Abstract Background The HVP vaccine is a useful tool for preventing cervical cancer. The purpose of this study is to determine the most frequent HPV genotypes in Equatorial Guinea in order to develop future vaccination strategies to apply in this country. Methods A campaign against cervical cancer was carried out in the area on a total of 1,680 women. 26 of the women, following cytological screening, were treated surgically with a loop electrosurgical excision procedure (LEEP. Cases were studied histologically and were genotyped from paraffin blocks by applying a commercial kit that recognized 35 HPV types. Results Cytological diagnoses included 17 HSIL, 1 LSIL, 5 ASC-H and 3 AGUS. Histological diagnosis resulted in 3 cases of microinvasive squamous cell carcinoma stage IA of FIGO, 9 CIN-3, 8 CIN-2, 2 CIN-1, 3 flat condylomas and mild dysplasia of the endocervical epithelium. Fifteen of twenty-five cases genotyped were positive for HPV (60%. HPV 16 and 33 were identified in four cases each, HPV 58 in two other cases, and HPV 18, 31, 52, and 82 in one case, with one HPV 16 and 58 coinfection. Conclusion The frequency of HPV types in the African area varies in comparison to other regions, particularly in Europe and USA. Vaccination against the five most common HPV types (16, 33, 58, 18, and 31 should be considered in the geographic region of West Africa and specifically in Equatorial Guinea.

    Full Text Available Introduction. Premalignant changes of the uterine cervix occur with similar frequency during pregnancy and in non­pregnant women. Due to the fact that any surgery on the cervix can jeopardize pregnancy, it is important to define the protocol of procedures for the treatment of these changes during pregnancy. Objective. The aim of the study was to investigate the natural course of premalignant cervical changes during pregnancy and the impact of their treatment on the pregnancy course. Methods. Study involved all patients with colposcopically, cytologically and hystopathologically diagnosed premalignant cervical changes during pregnancy from 2002 to 2008. Patients were divided into two groups according to the applied treatment during pregnancy: surgery or monitoring by regular colposcopic and cytological examinations. The two groups were compared concerning treatment outcome, persistence or regression of changes and pregnancy duration. Results. Study involved 58 patients. Spontaneous remission of lesions occurred after pregnancy in 63.79% of cases. Highgrade squamous intraepithelial lesion (H­SIL demonstrated a higher rate of persistency in comparison with low­grade squamous intraepithelial lesion (L­SIL (χ2=25.115; p<0.05. Only one finding of L­SIL progressed into H­SIL in the monitored group. Patients who underwent conization during pregnancy had a significantly more frequent preterm deliveries (χ2=14.369; p<0.05. Conclusion. The obtained high rate of spontaneous regression of cervical changes after pregnancy as well as the lower incidence of preterm births in patients who were not treated by conization during pregnancy, confirm that patients with premalignant cervical changes should be, if invasion is excluded, under follow­up throughout pregnancy by regular colposcopic and cytological examinations. Therapeutic conization, due to numerous complications, should be performed only when there is a suspected presence of a more severe form of

  13. Methylated Host Cell Gene Promoters and Human Papillomavirus Type 16 and 18 Predicting Cervical Lesions and Cancer.

    Full Text Available Change in the host and/or human papillomavirus (HPV DNA methylation profile is probably one of the main factors responsible for the malignant progression of cervical lesions to cancer. To investigate those changes we studied 173 cervical samples with different grades of cervical lesion, from normal to cervical cancer. The methylation status of nine cellular gene promoters, CCNA1, CDH1, C13ORF18, DAPK1, HIC1, RARβ2, hTERT1, hTERT2 and TWIST1, was investigated by Methylation Specific Polymerase Chain Reaction (MSP. The methylation of HPV18 L1-gene was also investigated by MSP, while the methylated cytosines within four regions, L1, 5'LCR, enhancer, and promoter of the HPV16 genome covering 19 CpG sites were evaluated by bisulfite sequencing. Statistically significant methylation biomarkers distinguishing between cervical precursor lesions from normal cervix were primarily C13ORF18 and secondly CCNA1, and those distinguishing cervical cancer from normal or cervical precursor lesions were CCNA1, C13ORF18, hTERT1, hTERT2 and TWIST1. In addition, the methylation analysis of individual CpG sites of the HPV16 genome in different sample groups, notably the 7455 and 7694 sites, proved to be more important than the overall methylation frequency. The majority of HPV18 positive samples contained both methylated and unmethylated L1 gene, and samples with L1-gene methylated forms alone had better prognosis when correlated with the host cell gene promoters' methylation profiles. In conclusion, both cellular and viral methylation biomarkers should be used for monitoring cervical lesion progression to prevent invasive cervical cancer.

    Full Text Available Introduction: The purpose of this study was to detect the types of the cervix lesions and to establish the correlations between age, environment of origin, diagnosis and gravity of the lesions. Methods: In the period 2009-2012, all cervical secretions from female subjects presented at Integrated Outpatient Unit, of the Clinical Hospital for Infectious Diseases, Cluj-Napoca, Romania were tested by Babeş-Papanicolaou examination. Babeş-Papanicolaou cytological smear was performed according to the 2001 Bethesda System criteria. Results: From 3153 cervical secretions (2736 female subjects from urban areas and 417 female subjects from rural areas with age 10 - 87 years, 2899 (91.9% smears (372 women from rural area and 2527 women from urban area had normal appearance. Premalignant or malignant lesions (positive cases were detected in 254 (8.1% smears (45 (12.1% cases from rural area, 209 (8.3% cases from urban area. In the urban area, most positive cases were recorded in the age range of 45-54 years, while in the rural areas in the age range of 35-44 years. The multivariate logistic regression analysis showed that environment and age significantly influenced the occurrence of positive cases (OR=1.44 95% CI 1.02-2.02, p=0.04 for rural area, OR=0.71 95% CI 0.60-0.85, p<0.001 for age. The correlation between age and the degree of severity diagnosis (r=-0.09, p=0.14 was not significant. Conclusions: Cervical lesions detected through Babeş-Papanicolaou test in adult women are more common in the rural area.

The aim of this one-year prospective clinical study was to evaluate the treatment results of compomer restorations (Dyract® eXtra/ Dentsply/De Trey, Konstanz, Germany with a single step self-etching dental adhesive (Xeno® III Dentsply/De Trey, Konstanz, Germany used for restoring class V lesions (non-carious and primary carious cervical lesions. Material and Methods. A total number of 62 class V restorations (n = 62 were placed by one dentist in 30 patients on incisors, canines and premolars. The fillings were placed due to different indications: non-carious cervical defects (n = 32 and primary carious lesions (n = 30. The restorations were evaluated by a single-blind design, according to the Modified United States Public Health Service system 6 and 12 months following the placement. The following were evaluated: retention, marginal integrity, marginal discoloration, wear, postoperative sensitivity and secondary caries. The statistical analysis compared the ratings of each criteria between materials using the Pearson chi-square or Fisher’s exact test at a level of significance of 5% (p<0.05. Results. Two restorations of the non-carious lesion group were lost after 6 months, and after 12 months one restoration was lost in the group of primary carious lesions. There were no statistically significant differences between restorations for all evaluated criteria in both groups. Conclusion. The compomer restorations in combination with a single step self-etching dental adhesive showed acceptable clinical performance in Class V lesions after one year of clinical service.

    Full Text Available Objective. To assess the prevalence and identified associated risk factors for precancerous cervical cancer lesions among HIV-infected women in resource-limited settings in Kenya. Methods. HIV-infected women attending the ART clinic at the Nazareth Hospital ART clinic between June 2009 and September 2010. Multivariate logistic regression model with odds ratios and 95% confidence intervals (CI were estimated after controlling for important covariates. Result. A total of 715 women were screened for cervical cancer. The median age of the participants was 40 years (range 18–69 years. The prevalence of precancerous lesions (CINI, CINII, CIN III, ICC was 191 (26.7%. After controlling for other variables in logistic regression analysis, cervical precancerous lesions were associated with not being on ART therapy; whereby non-ART were 2.21 times more likely to have precancerous lesions than ART patients [(aOR=2.21, 95% CI (1.28–3.83]. Conclusion. The prevalence of precancerous cervical lesions was lower than other similar settings. It is recommended that cancer screening of HIV-infected women should be an established practice. Availability and accessibility of these services can be done through their integration into HIV. Prompt initiation of HAART through an early enrollment into care has an impact on reducing the prevalence and progression of cervical precancerous lesions.

    Full Text Available Background & objectives: High-risk human papilloma virus (HR-HPV infection and its integration in host genome is a key event in malignant transformation of cervical cells. HPV16 being a dominant HR-HPV type, we undertook this study to analyze if viral load and physical state of the virus correlated with each other in the absence of other confounding variables and examined their potential as predictors of progressive cervical lesions. Methods: Both, viral load and integration status of HPV16 were determined by real time URR PCR and estimation of E2:E6 ratio in a total of 130 PGMY-RLB -confirmed, monotypic HPV16-infected cervical DNA samples from biopsies of cytology-confirmed low grade (LSIL, 30 and high grade (HSIL, 30, and invasive carcinoma, (squamous cell carcinoma SCC, 70 cases. Results: Investigation of DNA samples revealed a gradual increase in HPV16 viral load over several magnitudes and increased frequency of integration from LSIL to HSIL and HSIL to invasive cancer in relation to the severity of lesions in monotypic HPV16-infected cervical tissues. In a substantial number of precancer (11/60 and cancer cases (29/70, HPV16 was detected in concomitant mixed form. The concomitant form of HPV16 genome carried significantly higher viral load. Interpretation & conclusions: Overall, viral load and integration increased with disease severity and could be useful biomarkers in disease progression, at least, in HPV16-infected cervical pre-cancer and cancer lesions.

    Human Papillomavirus (HPV) is the most common sexually transmitted infection worldwide and it is responsible for most cases of uterine cancer. In Ecuador there is limited information about HPV types (and variants) in cancerous lesions; however, identifying the type-specific HPV prevalence in cervical lesions of women living in Ecuador is important to better predict the impact of HPV prophylactic vaccination in this country. We studied the prevalence of HPV types in cervical cancerous or precancerous lesions from 164 Ecuadorian women and found that 86.0% were HPV positive. The most common types were HPV16 (41.8%) and HPV58 (30.5%). Interestingly, HPV18 was detected only in 2.8% of the HPV-positive samples. Fifteen DNA sequences (genes E6 and L1) from 16 samples positive for HPV16 belonged to the European lineage, considered one of the least carcinogenic lineages, and 1 (6.25%) to the Asian-American lineage. Similar analysis in 12 HPV58 positive samples showed that 10 (83.3%) sequences grouped in sublineage A2, which belongs to the oldest HPV58 lineage, 1 belonged to A3 and 1 to lineage C. This study suggests that the currently used HPV vaccines (bivalent and tetravalent) may have lower effectiveness in Ecuador than in other geographic locations where HPV18 is more prevalent.

    Introduction Cervical cancer is the leading cause of cancer deaths among females in Angola and human papillomavirus (HPV) is the main risk factor for the development of pre-cancerous squamous intraepithelial lesions. The diversity and frequency of HPV types in Angola has yet to be reported. Aim To determine the frequency of HPV among women with squamous intraepithelial lesions from women in Luanda, Angola. Methods Study participants included women diagnosed with cytological abnormalities that voluntarily provided Pap smears (n = 64). Genomic DNA was extracted from the samples for use as templates in the PCR amplification of HPV sequences. PCR products were sequenced to determine HPV type. Results HPV DNA was detected in 71.9% (46/64) in the samples. A higher diversity of HPV types was found in the cytological lesions, such as ASCUS and LSIL (HPV16, 6, 18, 31, 58, 66, 70 and 82, in order of frequency) than that detected for HSIL and SSC (HPV16, 18, 6 and 33). The most prevalent HPV type were: HPV16, HPV6 and HPV18. Conclusion This is the first report on HPV type diversity and frequency in woman of Angola. The results suggest that large-scale studies across Africa would improve our understanding of interrelationship between HPV infections and cervical cancer. More directly, the identification of the HPV types most prevalent suggests that women in Angola would benefit from currently available HPV vaccines. PMID:28154623

    Full Text Available Background: Data from Egyptian studies provide widely varying estimates on the prevalence of preinvasive cervical lesions. The aim of this study was to estimate the rate of cervical intraepithelial neoplasia (CIN   in Egyptian women living in Alexandria to clarify the need for implementing a national organized screening program and a vaccination program in our community. Materials and Methods: The study was conducted over a 6 years period and covered the different socioeconomic levels to have a representative sample for women living in Alexandria. All women included did not have any cervical disorder related complaints. Conventional Pap smears were obtained and diagnosed using the Bethesda system. Women with abnormal Pap smears were managed according to the 2006 consensus guidelines within the available facilities. Persistent abnormal cytological results were referred for colposcopic biopsy. Histological results were grouped into: Reactive changes, CIN 1, CIN 2/CIN 3 and adenocarcinoma in-situ (AIS. Results: Out of the 6173 smears included in the study 6072 (98.36% were normal and only 101 (1.63% were abnormal. After colposcopic biopsies, 0.08% had CIN 1, 0.03% had CIN 2, 3 and 0.01% had AIS. Conclusion: We concluded that cervical cancer screening programs, although life-saving for a number of women, are not a sufficiently high priority in our community. Money for national health screening programs should preferably be directed more towards recruiting women for breast cancer screening, since breast cancer accounts for about 33% of all female cancers in Egypt ranking number one, while cervical cancer ranks number 13.

    This article describes an expedited, atraumatic technique of restoring cervical abrasion-erosion, abfraction or carious lesions using an alternative placement sequence of the dental rubber dam for adequate field isolation. As shown by this technique, the rubber dam retainer is modified and positioned on the tooth with subsequent placement of the dental dam material over theretainer and tooth. This technique saves time and provides good retraction of the gingival tissue and isolation of the cavity preparation from contamination (saliva, hemorrhage) that can potentially cause post-operative symptoms and possible restoration replacement.

    Full Text Available Background: Cervical cancer is the second leading cause of cancer death among women. In this cancer, the effects of prevention, early diagnosis and treatment more than other cancers decrease the mortality rate. In 1970 human papilloma virus (HPV was introduction as major etiologic factor of cervical cancer. Different studies throughout the world revealed strong correlation between HPV and cancerous & precancerous changes in epithelial cells. Since cell culture and serological methods can not recognize the virus and its subtypes, the importance of the molecular methods including polymerase chain reaction (PCR in early and definite diagnosis of virus is obvious. Methods: In this study, after patient selection using the related protocol and completion of the questionnaires, 100 samples from cancer lesions of cervix selected. Then DNA extraction from paraffin blocks performed using standard method. Multiplex PCR with two pairs of primer (one as internal control performed and the PCR product run on 8% polyacrylamid gel. Results: The results showed that 73% of the tissues were infected by HPV. Conclusion: This finding confirm the previous results based of correlation between HPV,and cervical cancer.

    In March 2012, the College of American Pathologists and American Society for Colposcopy and Cervical Pathology, in collaboration with 35 stakeholder organizations, convened a consensus conference called the Lower Anogenital Squamous Terminology (LAST) Project. The recommendations of this project include using a uniform, two-tiered terminology to describe the histology of human papillomavirus-associated squamous disease across all anogenital tract tissues: vulva, vagina, cervix, penis, perianus, and anus. The recommended terminology is "low-grade" or "high-grade squamous intraepithelial lesion (SIL)." This terminology is familiar to clinicians, because it parallels the terminology of the Bethesda System cytologic reports. Biopsy results using SIL terminology may be further qualified using "intraepithelial neoplasia" (IN) terminology in parentheses. Laboratory p16 tissue immunostaining is recommended to better classify histopathology lesions that morphologically would earlier have been diagnosed as IN 2. p16 is also recommended for differentiating between high-grade squamous intraepithelial lesions and benign mimics. The LAST Project recommendations potentially affect the application of current guidelines for managing cervical squamous intraepithelial lesions. The authors offer interim guidance for managing cervical lesions diagnosed using this new terminology with special attention paid to managing young women with cervical high-grade squamous intraepithelial lesions on biopsy. Clinicians should be aware of the LAST Project recommendations, which include important changes from prior terminology.

    Full Text Available We analyzed the immunohistochemical pattern of epidermal growth factor receptor (EGFR in cervical squamous intraepithelial lesions (SILs in correlation with L1 HPV capsid protein, in order to determine the relationship between EGFR expression and the infection status of human papillomavirus (HPV. The study included 40 cases, 24 LSIL (low grade SIL (CIN1, cervical intraepithelial neoplasia and 16 HSIL (high grade SIL (6 cases of CIN2 and 10 cases of CIN3. The immunoexpression of L1 HPV protein was assessed on conventional cervico-vaginal smears and EGFR was immunohistochemically evaluated on the corresponding cervical biopsies. The HPV L1 capsid protein was expressed in 45.83% of LSIL and 25% of HSIL. EGFR was overexpressed in 62,4% of HSIL (58,4% CIN2 and 41,6% CIN3 and 37,6% LSIL. The immunoexpression of L1 HPV has clinical application in the progression assessment of the cervical precancerous lesions without a correlation to the grade of the cervical SIL. EGFR is expressed by all proliferating squamous epithelial cells, thus corresponding with the grade of SIL. The evaluation of EGFR status, correlated with L1 HPV protein expression, can provide useful data of progression risk of cervical squamous intraepithelial lesions

    Current diagnostic approaches for primary cervical cancer screening, work-up of equivocal or positive screening results or follow- up after treatment of precancerous lesions primarily rely on the morphologic interpretation of squamous epithelial cells (Pap cytology), in some setting accompanied by the detection of human papillomavirus DNA and have largely contributed to remarkable reduction of disease incidence in countries with implemented screening programs. However, these approaches are limited by a poor sensitivity and reproducibility of Pap cytology and low specificity for high grade cervical intraepithelial neoplasia of HPV DNA detection assays. Early detection might be improved by complementing or even replacing these tests by markers which are more directly related to molecular events triggering HPV-induced carcinogenesis and thereby might deliver more accurate diagnostic performance. The delineation of molecular changes which occur during different stages of HPV infections and the identification of changes which induce neoplastic alterations allow for the detection of markers that specifically highlight the transforming stage of the infection where viral oncogenes are overexpressed and therefore allow for a more specific diagnosis of lesions that require treatment. The evaluation of such markers in clinical studies revealed that some indeed show an improved diagnostic performance compared to Pap cytology or HPV DNA tests only.

    Full Text Available INTRODUCTION: The magnitude of precancerous cervical cancer lesions as well as invasive cervical cancer is higher in HIV-infected women than non HIV-infected women. Thus, screening targeting HIV-infected women is being undertaken in developing countries, including Ethiopia. However, data on the prevalence and determinants of precancerous cervical cancer lesion among HIV-infected women in southern Ethiopia is lacking. Thus, this study aimed to assess the prevalence of and factors associated with precancerous cervical cancer lesion among HIV- infected women in southern Ethiopia. METHODS: A hospital-based cross-sectional study was conducted from October 2012 to February 2013 among HIV-infected women in Southern Ethiopia. Four hundred forty eight HIV-infected women who had been screened and treated for precancerous cervical cancer lesion were included in the study. Data were collected by using structured and pretested questionnaire. Visual inspection with acetic acid was applied for screening and treatment. SPSS version 16.0 was used for data entry and analysis. Logistic regression analysis was fitted and odds ratios with 95% Confidence intervals and p-values were computed to identify factors associated with precancerous cervical cancer lesion. RESULTS: Out of 448 study participants, 99 (22.1% were found to be positive for precancerous cervical cancer. Being currently on highly active antiretroviral treatment (AOR=0.52, 95%CI: 0.35, 0.92, history of sexually transmitted disease (AOR=2.30, 95%CI: 1.23, 4.29 and having only one lifetime sexual partner (AOR=0.33, 95%CI: 0.20, 0.56 were factors associated with precancerous cervical cancer lesion. CONCLUSIONS: The prevalence of precancerous cervical cancer lesion among HIV-infected women in southern Ethiopia was found to be high. Intervention to access all HIV-infected women like scaling up the limited services and awareness creation should be undertaken. Measures aimed at preventing the acquisition and

    Full Text Available Background/Aim. Overexpression of p16INK4a has been found to be linked with genomic integration of high-risk human papillomavirus (HPV and the developement of precancerous cervical intraepithelial lesions. The aim of this study was to examine is there a higher positive level of correlation between grade of histological dysplasia and p16INK4a level of expression in cervical smear, compared to results of Papanicolaou test. We also examined the correlation between HPV type, p16INK4a expression and Papanicolau test results. Methods. A total of 48 women with precanceorous cervical lesions and HPV cervicitis and 10 healthy women were enrolled in the study. Papanicolaou test, CINtecTM p16INK4a citological immunohistochemical test, polymerase chain reaction (PCR HPV 16, 18, 31, 33 analysis and histopathology of the lesion were performed in all the patients. Results. Comparing the results of Papanicoulaou test and the grade of histological dysplasia, low-grade squamous intraepithelial lesion (LSIL was confirmed in 38%, and high-grade squamous intraepithelial lesion (HSIL in 69.2% of the patients (p > 0.05. Significant positive correlation was found between p16 overexpression and grade of histological dysplasia (p = 0.000. Overexpression p16 was found in 70% of LSIL and 94.4% of HSIL. Positive correlation was found between p16 overexpression and grade of dysplasia in Papanicolaou test (p = 0.011. In 38% of LSIL and 15% of HSIL cases p16 was not expressed. The most frequently found HPV type in PCR analysis was HPV16. Analysing the results of p16 test according to HPV status and Papanicolaou test rather heterogenous results were obtained. Conclusion. In the patients with precancerous cervical lesions a higher level of correlation was found between the grade of histological dysplasia and p16INK4a level of expression in the cervical smear, compared to the results of Papanicolaou test.

    To determine factors that influence excision treatment outcome and recurrence of cervical squamous intraepithelial lesions (SIL) in women living with HIV infection, we analysed 1848 women who underwent excision treatment of cervical SIL at Tygerberg Hospital, Cape Town, South Africa. We compared treatment failure defined as presence of cervical intraepithelial neoplasia (CIN) I (presence of CIN I or higher at first follow-up after excision treatment) and post-excision recurrence of lesions (at one year or later) between women of HIV-positive, -negative or unknown status and examined factors associated with excision treatment outcome and recurrence. HIV-infected women experienced higher treatment failure than uninfected women (53.8% versus 26.9%, P treatment failure, more HIV-infected women had low-grade squamous intraepithelial lesion (LSIL) compared with uninfected women (64.9% versus 37.3%, P Treatment failure did not differ with the type of excision used in HIV-infected women. HIV-infected women were more likely to experience recurrence of lesions after excision treatment than uninfected women (hazard ratio 1.95, 95% confidence interval [CI] 1.59-2.39; P cervical SIL initiated on ART earlier may be expected to have better long-term excision treatment outcome. Close follow-up should be maintained after cervical excision treatment, especially in a setting of high HIV prevalence.

    Full Text Available Although screening for cervical cancer is recommended for women in most countries, the incidence of cervical cancer is greater in developing countries. Our goal was to determine the prevalence and factors associated with high-grade lesions/cervical cancer among women attending a reference clinic in Brazil and evaluate the correlation of histology with cytology, colposcopy and the high-risk HPV (HR-HPV tests.A cross-sectional study of women attending a colposcopy clinic was carried out. The patients were interviewed to collect demographic, epidemiological and clinical data. Specimens were collected for cervical cytology, Chlamydia trachomatis and HPV testing using the Hybrid Capture (HC and PCR tests. Colposcopy was performed for all patients and biopsy for histology when cell abnormalities or cervical intraepithelial neoplasia (CIN were present.A total of 291 women participated in the study. The median age was 38 years (DIQ: 30-48 years. The prevalence of histologically confirmed high-grade lesions/cervical cancer was 18.2% (95%, CI: 13.8%-22.6%, with 48 (16.5% cases of CIN-2/CIN-3 and 5 (1.7% cases of invasive carcinoma. In the final logistic regression model, for ages between 30 and 49 years old [OR = 4.4 (95%: 1.01-19.04, history of smoking [OR = 2.4 (95%, CI: 1.14-5.18], practice of anal intercourse [OR = 2.4 (95%, CI: 1.10-5.03] and having positive HC test for HR-HPV [OR = 11.23 (95%, CI: 4 0.79-26, 36] remained independently associated with high-grade lesions/cervical cancer. A total of 64.7% of the cases CIN-3\\Ca in situ were related to HPV-16. Non-oncogenic HPV were only found in CIN-1 biopsy results. Compared to histology, the sensitivity of cytology was 31.8%, the specificity 95.5%; the sensitivity of colposcopy for high-grade lesions/cervical cancer was 51.0%, specificity was 91.4% and the concordance with HPV testing was high.The results confirm an association of HR-HPV with precursor lesions for cervical cancer

    Cervical cancer is a major public health problem in Morocco. The cervical cancer has a long precancerous period that provides an opportunity for the screening and treatment. Improving screening tests is a priority goal for the early diagnosis of cervical cancer. This study was conducted to evaluate the combination of p16(INK4a) protein expression, human papillomavirus (HPV) typing, and histopathology for the identification of cervical lesions with high risk to progress to cervical cancer among Moroccan women. A total of 96 cervical biopsies were included in this study. Signal amplification in situ hybridization with biotinylated probes was used to detect HPV. Immunohistochemistry was used to evaluate the expression of p16(INK4a) protein. HPV DNA was detected in 74.0% of the biopsies (71/96). Of the seventy-one positive HPV cases, we detected 67.6% (48/71) of high risk (HR)-HPV (HPV 16 and 18), 24% of low risk-HPV (HPV 6 and 11), 1.4% intermediate risk-HPV (HPV 31, 33, and 35), and 7% coinfections (HPV 6/11 and 16/18). Overexpression of p16(INK4a) protein was observed in 72.9% (70/96) of the biopsies. In addition, p16(INK4a) protein detection was closely correlated with recovery of HR HPV. Our result showed that p16(INK4a) expression level is correlated with HR-HPV status.

    Full Text Available Background: Cervical cancer is the most common cancer among females in India. It is also one of the major causes of deaths among them. Papanicolaou (Pap cytological test helps in detecting the early epithelial abnormalities in cervical cells. The morbidity and mortality due to cervical cancer has come down in countries with well-established screening programmes at national level. This study was conducted to emphasize the value of cervical screening as a tool for early detection of non-neoplastic and neoplastic lesions of cervix. Slide positivity rate was computed and clinico-pathological correlation was done. Methods: This cross-sectional study was conducted from January 2012 to December 2014 (3 years, on 2202 women aged between 20-70 years coming for a Pap smear examination in a tertiary care hospital in Bareilly, India. After staining with conventional Papanicolaou technique, all cases were classified as per Bethesda nomenclature (2001. Results: Out of 2202 cases, 85.16% slides were found to be negative for intraepithelial abnormalities and 14.84% slides were labelled as positive for epithelial lesions. 97.67% of high grade lesions were found in women more than 40 years. Smears with epithelial cell abnormality were found more common in older age groups whereas smears negative for epithelial cell abnormality were found more common in young age groups. Conclusion: Pap test is a cost effective cancer screening and is a simple method to detect various lesions of cervix, non-neoplastic as well as neoplastic. High risk screening programmes should be directed to all women >40 years. Pap test is especially useful to diagnose precancerous lesions of cervix, thereby early detection of these lesions and subsequent proper treatment can be helpful in prevention of cervical cancer.

    Objective In Mexico cervical cancer (CC) is the most common cause of death from neoplasia in women. Study aimed to analyze the current distribution of Human papillomavirus (HPV) types in women from Nayarit, Mexico, with Squamous intraepithelial lesions (SIL) and Cervical cancer (CC). Methodology Between January 2011 and July 2013, cervical samples were collected from female residents of the Mexican state of Nayarit and were analyzed by means of a LINEAR ARRAY® HPV genotyping test. Data analyses were performed using Stata ver. 8.0 statistical software. Results Of the samples analyzed, 91.2%, HPV DNA was detected. Of these positive samples, 82% were High-risk (HR) viral types. The most prevalent HPV genotypes identified were 16, 58, 31, 18, and 70. Forty two percent of participants had a single infection, while 23 and 26% of participants were infected with two or more HPV genotypes, respectively. HPV 16 was the most prevalent genotype identified and was frequently present as a co-infection with HPV types 18, 51, 52, 59, 66, or 70. Conclusion Women <20 years of age were most often infected with HPV, and the HPV Quadrivalent vaccine (types 16, 18, 6, and 11), currently available in Mexico, no confers protection against a subset of the HPV genotypes identified in the present study (58, 31, 70, and 35). Thus, it is important evaluate the geographical distribution of specific HPV genotypes in all health of center across Mexico in order to implement a successful vaccination program and to diagnose CC in its early stages.

    Thirty patients suffering from mass lesion in the parotid gland or cervical region were examined by computed tomography (CT). The photographed images were compared with the findings and pathological diagnoses obtained by surgical procedures. The conclusions were as follows: 1) Plain CT demonstrated the location of the parotid tumor. Contrast enhancement seemed to delineate the margin of the tumor more clearly. 2) By contrast enhancement, the branchiogenic cyst was differentiated from the parotid tumor, as a low density mass with an enhanced cyst wall. 3) Parotid tumors enhanced by contrast material did not always appear as solid tumors. 4) In some cases, CT numbers indicated the contents of the tumor. 5) The extension of the tumor to the parapharyngeal space was clearly depicted on CT. 6) It seemed to be difficult to evaluate the relationship of the parotid tumor to the facial nerve on plain CT.

    To determine the prevalence and predictors of cervical squamous intraepithelial lesions (SIL) among HIV-infected women in Tanzania, a cross-sectional study was conducted among HIV-infected women at HIV care and treatment clinics. A Papanicolaou (Pap) smear was used as a screening tool for detection of cervical SIL. From December 2006 to August 2009, 1365 HIV-infected women received cervical screening. The median age was 35 (interquartile range [IQR]: 30-42) years, and the median CD4 + cell count was 164 (IQR: 80-257) cells/mm(3). The prevalence of cervical SIL was 8.7% (119/1365). In multivariate analysis, older age (≥50 versus 30-cervical inflammation (PR, 1.73; 95% CI, 1.16-2.60, p = 0.008) were associated with an increased risk of cervical SIL. Women with advanced WHO HIV disease stage (IV versus I/II: PR, 3.45; 95% CI, 1.35-8.85, p for trend = 0.01) had an increased risk for high-grade SIL. In resource-limited settings where it is not feasible to provide cervical cancer prevention services to all HIV-infected women, greater efforts should focus on scaling-up services among those who are older than 50 years, with lower CD4 cell counts and advanced HIV disease stage.

    Full Text Available OBJECTIVES: Adhesive systems are continuously being introduced to Dentistry, unfortunately often without sufficient clinical validation. The aim of this study was to evaluate the clinical performance of cervical restorations done with three different adhesive systems. MATERIAL AND METHODS: 158 non-carious cervical lesions of 23 patients were restored with a nanofilled composite resin (Filtek Supreme, 3M/ESPE combined with Single Bond (3M/ESPE, group SI, Clearfil SE (Kuraray Medical Inc., group CL and Xeno III (De Trey Dentsply, group XE. In groups SI-B, CL-B and XE-B, the outer surface of the sclerotic dentin was removed by roughening with a diamond bur before application of the respective adhesive systems. In groups CL-BP and XE-BP, after removal of the outer surface of the sclerotic dentin with the bur, the remaining dentin was etched with 37% phosphoric acid and the self-etch adhesive systems Clearfil SE and Xeno III were applied, respectively. Lesions were evaluated at baseline, and restorations after 3 months, 1 year and 2 years using modified USPHS criteria. RESULTS: After 2 years, no significant difference was found between the retention rates of the groups (p >0.05. Although groups CL and SI showed significantly better marginal adaptation than group XE (p0.05. After 2 years no significant difference was observed among the marginal staining results of all groups (p>0.05. CONCLUSION: Although all adhesive systems showed similar retention rates, Clearfil SE and Single Bond showed better marginal adaptation than Xeno III after 2 years of follow-up.

    To determine human papillomavirus (HPV) types distribution in cervical lesions in a Southern Italian female population in Messina and their relationship between HPV type and grade of colposcopic and histopathological abnormality, a total of 253 women aged 17-68 years, with previous cytological abnormalities, were included in this study. HPV-DNA testing, colposcopy and biopsy were performed. For each sample, cervical cells were collected by centrifugation and DNA was extracted, followed by a PCR-based HPV-DNA assay and reverse dot blot genotyping. HPV-16 was found the most common type (46.6 %) followed by HPV-31 (26.9 %), -6 (18.6 %), -58 (8.8 %), -18 (6.7 %), -66 (5.7 %), -52 and -53 (4.7 %). Out of 62 women with abnormal transformation zone (ATZ) area compatible with squamous intraepithelial lesion (SIL) or cervical cancer (CC), 64.5 % was found high risk (HR) HPV-positive. Moreover the severity of the colposcopic diagnosis was positively correlated with the higher HPV oncogenicity risk (HPV-16 P = 0.023; and HPV-53 P = 0.047). The HPV-16 was found the most prevalent type within each histological category: 66.7 %, 31.2 %, 44 % and 37.2 % of CC, high grade (H)SIL, low grade (L)SIL and chronic cervicitis respectively; followed by HPV-31 present in 25 %, 8 %, and 13.3 % of HSIL, LSIL and chronic cervicitis respectively. A higher HPV incidence than the rest of Italy was found, in agreement with that detected by other authors for the South of the country. These data provide further information about the types prevalence in women with cervical lesions living in Eastern Sicily, suggesting the introduction of new targeted vaccines against a wider spectrum of HPV.

    Enhanced expression of the HPV 16 E6-E7 oncogenes may trigger neoplastic transformation of the squamous epithelial cells at the uterine cervix. The HPV E2 protein is a key transcriptional regulator of the E6-E7 genes. It binds to four E2 binding sites (E2BSs 1-4) in the viral upstream regulatory region (URR). Modification of E2 functions, for example, by methylation of E2BSs is hypothesized to trigger enhanced expression of the viral E6-E7 oncogenes. In the majority of HPV-transformed premalignant lesions and about half of cervical carcinomas HPV genomes persist in an extra-chromosomal, episomal state, whereas they are integrated into host cells chromosomes in the remaining lesions. Here we compared the methylation profile of E2BSs 1-4 of the HPV 16 URR in a series of 18 HPV16-positive premalignant lesions and 33 invasive cervical cancers. CpGs within the E2BSs 1, 3, and 4 were higher methylated in all lesions with only episomal HPV16 genomes compared with lesions displaying single integrated copies. Samples with multiple HPV16 integrated copies displayed high methylation levels for all CpGs suggesting that the majority of multiple copies were silenced by extensive methylation. These data support the hypothesis that differential methylation of the E2BSs 1, 3 and 4 is related to the activation of viral oncogene expression in cervical lesions as long as the viral genome remains in the episomal state. Once the virus becomes integrated into host cell chromosomes these methylation patterns may be substantially altered due to complex epigenetic changes of integrated HPV genomes.

    The aims of this study was to determine proportion of HIV infected women with cervical pre-malignant lesions; and compare the use of Visual Inspection of the cervix after application of Acetic acid (VIA) and Papanicolau (Pap) smear in screening for cervical premalignant lesions in HIV positive women attending Care and Treatment Centre (CTC) at Muhimbili National Hospital (MNH), Dar es Salaam, Tanzania. A total of 316 women aged 18-70 years had a Pap smear taken for cytology, followed by spraying onto the cervix with 4% acetic acid and then inspecting it. Cytology was considered negative when there was no Cervical Intraepithelial Neoplasia (CIN) lesion reported from the Pap smear taken, and positive if CIN lesion 1, 2 or 3 was reported. Detection of a well-defined, opaque acetowhite lesion close to the squamocolumnar junction or close to the external cervical os constituted a positive VIA. Out of 316 women, 132 women had acetowhite lesions on VIA, making the proportion of abnormal cervical lesions to be 42.4%. One hundred and one out of 312 women (32.4%) had CIN lesions detected on Pap smear. The proportion of agreement between these two tests was 0.3. The proportion of agreement was moderate in women with advanced WHO HIV clinical stage of the disease and in women not on ART (Anti Retroviral Therapy). Women with CD-4 count less than 200 cells/mm3 had more abnormal cervical lesions. There is considerable proportion of HIV positive women with premalignant lesions of the cervix. Considering the proportion of HIV women with abnormal lesions and the difficulty in logistics of doing Pap smear in low resource settings, these results supports the recommendation to introduce screening of premalignant lesions of the cervix using VIA to all HIV infected women.

    Polymorphisms in chemokine receptors play an important role in the progression of cervical intraepithelial neoplasia (CIN) to cervical cancer (CC). Our study examined the association of CCR2-64I (rs1799864) andCCR5-Δ32 (rs333) polymorphisms with susceptibility to develop cervical lesion (CIN and CC) in a Brazilian population. The genotyping of 139 women with cervical lesions and 151 women without cervical lesions for the CCR2-64I and CCR5-Δ32 polymorphisms were performed using polymerase chain reaction-restriction fragment length polymorphism. The individuals carrying heterozygous or homozygous genotypes (GA+AA) for CCR2-64I polymorphisms seem to be at lower risk for cervical lesion [odds ratio (OR) = 0.37, p = 0.0008)]. The same was observed for the A allele (OR = 0.39, p = 0.0002), while no association was detected (p > 0.05) with CCR5-Δ32 polymorphism. Regarding the human papillomavirus (HPV) type, patients carrying the CCR2-64Ipolymorphism were protected against infection by HPV type 16 (OR = 0.35, p = 0.0184). In summary, our study showed a protective effect ofCCR2-64I rs1799864 polymorphism against the development of cervical lesions (CIN and CC) and in the susceptibility of HPV 16 infection.

    The aim of this study was to evaluate the 6- and 12-month clinical performance of four adhesion strategies from the same manufacturer (Kerr) in non-carious cervical lesions (NCCLs) using two evaluation criteria. Thirty-five patients, with at least four NCCLs each, participated in this study. After samplesize calculation, 180 restorations were assigned to one of the following groups: OFL (Optibond FL), OSP (Optibond Solo Plus), XTR (Optibond XTR), and AIO (Optibond All-In-One). The composite resin Filtek Supreme Ultra (3M ESPE) was placed incrementally. The restorations were evaluated at baseline, after 6 months, and after 12 months, using both the FDI and the USPHS-modified criteria. Statistical analyses were performed with Friedman repeated measures, ANOVA by rank, and the McNemar test for significance in each pair (α=0.05). Six restorations (2 for OFL, 1 for OSP, 2 for XTR, and 1 for AIO) were lost at 12 months (P>0.05 for both evaluation criteria). Marginal staining was observed in seven restorations using the FDI criteria (P>0.05) and three restorations using the USPHSmodified criteria (P>0.05). Eight restorations (2 for OSP, 3 for XTR, and 3 for AIO) were classified as Bravo for marginal adaptation using the USPHSmodified criteria (P>0.05). However, 62 restorations (14 for OFL, 12 for OSP, 15 for XTR, and 21 for AIO) were classified as Bravo using the FDI criteria (P>0.05). The four adhesion strategies showed similar clinical retention at 6 and 12 months. The FDI evaluation criteria tend to be more sensitive than the USPHS-modified criteria.

    Cervical cancer is the third most common cancer in women worldwide. The hypermethylation of P16, TSLC-1 and TSP-1 genes was analyzed in squamous cell carcinomas (SCC), cervical intraepithelial lesions (CIN) and adenocarcinomas (ADC) of the uterine cervix (total 181 lesions). Additionally human papillomavirus (HPV) type, EPB41L3, RASSF1 and RASSF2 hypermethylation were tested in ADC and the results were compared with those obtained previously by our group in SCC. P16, TSLC-1 and TSP-1 hypermethylation was more frequent in SCCs than in CINs. These percentages and the corresponding ones for EPB41L3, RASSF1 and RASSF2 genes were also higher in SCCs than in ADCs, except for P16. The presence of HPV in ADCs was lower than reported previously in SCC and CIN. Patients with RASSF1A hypermethylation showed significantly longer disease-free survival (P = 0.015) and overall survival periods (P = 0.009) in ADC patients. To our knowledge, this is the first description of the EPB41L3 and RASSF2 hypermethylation in ADCs. These results suggest that the involvement of DNA hypermethylation in cervical cancer varies depending on the histological type, which might contribute to explaining the different prognosis of patients with these types of tumors.

    Cervical cancer is the second most common cancer among women worldwide. Infection with the human immunodeficiency virus (HIV) and its related immunosuppression are associated with an increased risk of prevalent, incident, and persistent squamous intraepithelial lesions (SILs) of the cervix. The objective of the study was to describe the prevalence and predictors of high-risk HPV and cervical cancer to support the need for strengthening cervical cancer screening programs for HIV infected women in Kenya. A cross sectional study was conducted in a hospital in Central Kenya, Kiambu district. The study population constituted of HIV positive women attending the ART treatment clinic. A total of 715 HIV positive women initiated on Antiretroviral Therapy (ART) were enrolled in this study. About 359 (52.1%) were less than 40 years of age and 644 (90.3%) of the patients were widowed. About 642 (92.6%) of the HIV infected women were in follow-up period of ≥ 1 year. The outcome/prognosis of the patients undergoing ICC was 3 cured, 5 good and 4 poor respectively. In a multivariable ordinal logistic regression analysis showed that for a one-unit decrease of CD4, we expect 1.23 log odds of increasing the severity of cervical cancer (B = 1.23, P treatment, enrolling patients on HAART with higher CD4 counts is recommended to see the net effect of HAART response.

    Human papillomavirus (HPV) types 16/18, included in HPV vaccines, contribute to the majority of cervical cancer, and a substantial proportion of cervical intraepithelial neoplasia (CIN) grades 2/3 or worse (CIN2+/CIN3+) including adenocarcinoma in situ or worse. The aim of this study was to quantify the effect of quadrivalent HPV (qHPV) vaccination on incidence of CIN2+ and CIN3+. A nationwide cohort of girls and young women resident in Sweden 2006-2013 and aged 13-29 (n = 1,333,691) was followed for vaccination and histologically confirmed high-grade cervical lesions. Data were collected using the Swedish nationwide healthcare registers. Poisson regression was used to calculate incidence rate ratios (IRRs) and vaccine effectiveness [(1-IRR)x100%] comparing fully vaccinated with unvaccinated individuals. IRRs were adjusted for attained age and parental education, and stratified on vaccination initiation age. Effectiveness against CIN2+ was 75% (IRR = 0.25, 95%CI = 0.18-0.35) for those initiating vaccination before age 17, and 46% (IRR = 0.54, 95%CI = 0.46-0.64) and 22% (IRR = 0.78, 95%CI = 0.65-0.93) for those initiating vaccination at ages 17-19, and at ages 20-29, respectively. Vaccine effectiveness against CIN3+ was similar to vaccine effectiveness against CIN2+. Results were robust for both women participating to the organized screening program and for women at prescreening ages. We show high effectiveness of qHPV vaccination on CIN2+ and CIN3+ lesions, with greater effectiveness observed in girls younger at vaccination initiation. Continued monitoring of impact of HPV vaccination in the population is needed in order to evaluate both long-term vaccine effectiveness and to evaluate whether the vaccination program achieves anticipated effects in prevention of invasive cervical cancer.

    A specific immune response to human papillomavirus (HPV) in the cervical microenvironment plays a key role in eradicating infection and eliminating mutated cells. However, high-risk HPVs modulate immune cells to create an immunosuppressive microenvironment, and induce these immune cells to produce interleukin 10 (IL-10). This production of IL-10, in conjunction with HPV infection, contributes to the appearance of cervical neoplastic lesions. We sought to characterize the IL-10-producing cellular phenotype, and investigate the influence of host and HPV factors upon the induction of an immunosuppressive microenvironment. Immunohistochemical analysis demonstrated an increase in IL-10 production by keratinocytes, macrophages and Langerhans cells in high-grade cervical lesions and cervical cancer. This increase was more pronounced in patients older than 30 years, and was also correlated with high viral load, and infection with a single HPV type, particularly high-risk HPVs. Our results indicate the existence of a highly immunosuppressive microenvironment composed of different IL-10-producing cellular phenotypes in cervical cancer samples, and samples classified as high-grade cervical lesions (cervical intraepithelial neoplasia stages II and III). The immunosuppressive microenvironment that developed for these different cellular phenotypes favours viral persistence and neoplastic progression.

    Full Text Available Cervical myelopathy (CM is mostly a degenerative process ending in myelopathic and/or radiculopathic syndromes. On T2-weighted magnetic resonance imaging (MRI, CM appears as a hyperintense area near the spondylotic spine. This high intensity signal depends on the impact of outer forces and their duration. It also determines the prognosis of the surgical candidate. A 40-year-old male patient admitted to our clinic with right upper extremity weakness and hypoesthesia that had started 2 months earlier. On neurological examination there was 2/5 motor weakness of right biceps brachii, and hypoesthesia over right C6 dermatome. Right upper extremity deep tendon reflexes were hypoactive, but lower ones were hyperactive. After clinical and radiological work-up, preliminary diagnosis was directed to a spinal intramedullary tumor. Total resection of the herniated cervical disc fragment and the mass lesion was managed. Pathology of the mass lesion was compatible with subacute infarct tissue and inflammatory response. Final diagnosis was CM under effect of cervical disc herniation. Contrast-enhanced spinal cord myelopathic lesions are very rare and resemble much more tumors and inflammatory processes. However, the principal treatment approach totally differs depending on pathology. When there are both a disc herniation and a high clinical suspicion; biopsy should be delayed. The most probable solution will be surgery for the disc disease with thorough preoperative scanning of vascular malformations; clinical and radiological close follow-up after surgery. Biopsy or surgical resection can be performed if patient deteriorates despite the primary surgery.

    The objective of the study was to determine the dynamics of precancerous lesions in women of a cohort treated for cervical intraepithelial neoplasia (CIN) and followed up over the next two years. The conditional probability of failure was calculated using the Kaplan-Meier method, and the raw and adjusted hazard ratios (HR) were determined using Cox regression with a p-value entry of history of more frequent pregnancies and a histological diagnosis of CIN II/III are directly correlated with risk of CIN treatment failure, whereas being in a stable relationship is inversely correlated with this risk.

    The overal survival of patients with cervical cancer has improved due to detection at an early stage and availability of comprehensive treatments in China. As patients’ lives prolonged, it is important to understand their health-related quality of life (QoL) during and after treatment. We used the EQ-5D questionnaire to assess QoL of 194 patients with cervical lesions at Sichuan University West China Second Hospital between May 2010 and January 2011. Patients were surveyed before primary treatment and at 1, 3, and 6 months after primary treatment. Results showed a consistent decline in EQ-5D scores in the spectrum of cervical lesions at each time point after treatment (alP < 0.05). For patients with precursor lesions, there was an increasing trend along the timeline of treatment (P < 0.01). For patients with early-stage cervical cancer, EQ-5D scores declined in the first month (P = 0.01) and gradualy increased to higher levels at 6 months post-treatment than those before treatment (P < 0.01). EQ-5D scores followed a similar trend in patients with advanced cervical cancer (P = 0.04), though they did not statisticaly rebound after 6 months (0.84± 0.19 vs. 0.86± 0.11,P = 0.62). Regarding advanced cervical cancer, EQ-5D scores for women above 40 years of age appeared to recover more rapidly and reached higher levels than those for women below 40 years (P = 0.03). Caution and extra care are recommended in the early period of cervical cancer treatment given the slight deterioration in the QoL, and in particular, for younger cervical cancer patients. Our study implies that health care providers may need to improve the health-related QoL of cervical cancer patients.

    Background: Cervical cytology is the best single method for large screening of the population in identifying precancerous lesions of the uterine cervix. Aim: To estimate the frequency of human papillomavirus (HPV) positivity in a group of Albanian women, the prevalence of vaginal coinfections, and the relationship of coinfections with HPV, as well as their role in metaplasia or cervical intraepithelial lesions (CIN). Materials and Methods: In this retrospective study, 2075 vaginal smears were examined. The Papanicolaou stain was used for all slides. The New Bethesda System 2001 was used for the interpretations of the smears. Data analysis was completed using the Statistical Package for the Social Sciences version 19.0. Results: Prevalence of HPV positivity was 43.9% with an average age of 35.48 ± 9.27 years. Candida coinfection resulted in 57.8% of HPV positive women with a significant relationship between them. Gardnerella coinfection resulted in 36 (23%), mixed flora in 34 (8%), and Trichomonas vaginalis in 50% of HPV positive woman. Among the women with positive HPV, 19% had CIN, 8% had metaplasia, and 1% had metaplasia and CIN; 9% of the women with HPV had CIN1 and one of the coinfections. Conclusions: There is a strong relationship between CIN1 and HPV positivity as well as between CIN1 and coinfections. HPV infection is a major factor contributing to metaplasia, and bacterial coinfections in HPV positive women have a statistically significant impact in the development of metaplasia. PMID:28182076

    Background Cervical cancer is the second most common cause of death from cancer among women worldwide.Human papillomavirus(HPV)plays a central role in the etiology of cervical cancer.It is important to describe the prevalence of HPV infection in different types of cervical lesions and to explore the relation between HPV viral load and the severity of cervical lesions.Methods To describe the HPV infection prevalence and viral load in different age groups,we retrospectively investigated 6405 cases of women who were organized by their units to take health-examination.They were given Hybrid Capture ll tests between Janury 2005 and December 2006.The correlation between HPV viral load and pathology was assessed.Results Overall HPV infection prevalence was 29.1%(1864/6405),while in women 18-20 years old it was 54.4% (31/57),the highest among all age groups.After declining rapidly,HPV prevalence stabilized at about 30.0%in women aged 30 and older.Of the 6405 women,1 483 women had a colposcopic biopsy and 33.2%(492/1 483)were positive for HPV DNA.Twenty-one percent of women with a normal diagnosis(238/1 095)had HPV infection,a statistically significantly lower prevalence than in women with cervical lesions,including those with cervical intraepithelial neoplasia (68.8%in CINl,66.7% in CIN2,and 76.5%in CIN3)or with cervical cancer(94.1%).The correlation coefficient between viral load and cervical lesion severity was 0.134,which was not tatistically significant(P=0.075).Viral load values in women with CINs and cervical cancer were calculated,and no significant differences were dentified.Conclusions The revalence of high-risk HPV infection among women attending hospitals for health-examination in Shanghai is similar to the worldwide rate.HPV viral load can distinguish ervical lesions from normal individuals but cannot adequately predict the severity of cervical lesions.

    This study compares the detection rates of Chlamydia trachomatis by two techniques, direct immunofluorescence (IMF) and real time polymerase chain reaction (PCR), in patients with and without intra-epithelial cervical lesions (SIL) in Recife. We conducted a transversal study involving 35 women with SIL and 35 without SIL attended at Ambulatório Especializado da Mulher, Recife, Brazil. They were tested for Chlamydia trachomatis using two techniques, direct IMF or real time PCR. The rates of Chlamydia trachomatis detection were compared and the association with intra-epithelial cervical lesions was determined using the chi-square test at a 5% level of significance. Concordance between the tests was evaluated using kappa. The global prevalence of Chlamydia infection was 47.1% by direct IMF and 58.6% by real time PCR. A significant association was observed between Chlamydia diagnosis and presence of intra-epithelial cervical lesions, with about 80% positive results by direct IMF and 77.1% by real time PCR. However, the detected rate of infection with Chlamydia trachomatis was significantly greater in patients without intra-epithelial cervical lesions tested by real time PCR (40%) when compared to direct IMF (14.3%). The concordance between the tests was weak, with a kappa coefficient of 0.4. Both real time PCR and direct IMF detected elevated rates of Chlamydia infection in patients with intra-epithelial cervical lesions (80%) but the tests were discordant when patients without cervical lesions were tested, possibly because sensitivity of real time PCR is greater.

    Full Text Available Abstract Background Since the mid-1990s, there have been growing efforts to prevent cervical cancer in less-developed countries through the development of innovative screening approaches such as visual inspection of the cervix associated with same day management of cervical lesions with cryotherapy or loop electrosurgical excision procedure (LEEP. In the past, promising cancer screening interventions have been widely promoted despite incomplete evidence, only to become the subject of intense controversies about ensuing net health benefit. Because the efficacy and effectiveness of the new protocols for global cervical cancer screening have not been well characterized yet, and as a contribution to the evaluation of the balance between the benefits and risks of these protocols, we reviewed the literature on the safety of cryotherapy and LEEP for cervical intraepithelial neoplasia (CIN in low- and middle-income countries. Methods We searched 12 databases (Medline, Google Scholar, Scopus, Cochrane Library, Web of Science, OCLC, PAIS International Database, WHO Global Health Library, CINAHL, Science.gov, NYAM Grey Literature Report, and POPLINE for original research published between January 1995 and April 2009. Both peer-reviewed publications and items of "grey" literature were retrieved; no language restriction was applied. We calculated the median (minimum, maximum reported rate for each harm considered. Because of limitations and heterogeneity in the data, no formal meta-analysis was performed. Results The search identified 32 articles that reported safety data from 24 cryotherapy and LEEP studies. The combined sample consisted of 6,902 women treated by cryotherapy and 4,524 women treated by LEEP. Most studies were conducted in reference or research settings in Asia and Africa. Short-term harms of cryotherapy and LEEP appeared to be similar to those described in the literature from high-income countries. Information was sparse on HIV-related harms

    Full Text Available The purpose of this study concerning the role of electrotherapy and of physical therapy in the recovery of cervical arthrosis is to maintain a high quality family, social and professional activity, by eliminating the pain and the muscle contractures. The hypothesis that was the starting point of this paper was that: if we associate electrotherapy techniques and cervical spine alignment techniques to the recovery programme, the pain and the paresthesias will diminish until they fade away for good. The study was conducted on a number of 24 subjects with the diagnosis of cervical arthrosis, over a period of 6 months. The subjects in the experimental group were 12 and they benefited from electrotherapy and physical therapy, while those in the control group had only medication. The methods, procedures and the techniques used in the recovery for the subjects included in the experimental group were: TENS currents, ultrasounds, tractions on an axis, facilitation techniques and the adjustment of the cervical spine. The results materialized in: the disappearance of pain, of paresthesias and of muscle contractions obtain in a relatively short period of time, allows us to notice the benefit of associating electrotherapy and physical therapy to the recovery of cervical arthroses. The conclusions underline the importance of the position adopted during all the activities that require head flexion in order to prevent the rectitude of the cervical spine and implicitly the pain, the paresthesias and the contractures.

    Full Text Available Abstract Background Persistent high risk HPV infection can lead to cervical cancer, the second most common malignant tumor in women worldwide. NK cells play a crucial role against tumors and virus-infected cells through a fine balance between activating and inhibitory receptors. Expression of triggering receptors NKp30, NKp44, NKp46 and NKG2D on NK cells correlates with cytolytic activity against tumor cells, but these receptors have not been studied in cervical cancer and precursor lesions. The aim of the present work was to study NKp30, NKp46, NKG2D, NKp80 and 2B4 expression in NK cells from patients with cervical cancer and precursor lesions, in the context of HPV infection. Methods NKp30, NKp46, NKG2D, NKp80 and 2B4 expression was analyzed by flow cytometry on NK cells from 59 patients with cervical cancer and squamous intraepithelial lesions. NK cell cytotoxicity was evaluated in a 4 hour CFSE/7-AAD flow cytometry assay. HPV types were identified by PCR assays. Results We report here for the first time that NK cell-activating receptors NKp30 and NKp46 are significantly down-regulated in cervical cancer and high grade squamous intraepithelial lesion (HGSIL patients. NCRs down-regulation correlated with low cytolytic activity, HPV-16 infection and clinical stage. NKG2D was also down-regulated in cervical cancer patients. Conclusion Our results suggest that NKp30, NKp46 and NKG2D down-regulation represent an evasion mechanism associated to low NK cell activity, HPV-16 infection and cervical cancer progression.

    Human papillomavirus (HPV) types 16/18, included in HPV vaccines, contribute to the majority of cervical cancer, and a substantial proportion of cervical intraepithelial neoplasia (CIN) grades 2/3 or worse (CIN2+/CIN3+) including adenocarcinoma in situ or worse. The aim of this study was to quantify the effect of quadrivalent HPV (qHPV) vaccination on incidence of CIN2+ and CIN3+. A nationwide cohort of girls and young women resident in Sweden 2006–2013 and aged 13–29 (n = 1,333,691) was followed for vaccination and histologically confirmed high‐grade cervical lesions. Data were collected using the Swedish nationwide healthcare registers. Poisson regression was used to calculate incidence rate ratios (IRRs) and vaccine effectiveness [(1‐IRR)x100%] comparing fully vaccinated with unvaccinated individuals. IRRs were adjusted for attained age and parental education, and stratified on vaccination initiation age. Effectiveness against CIN2+ was 75% (IRR = 0.25, 95%CI = 0.18–0.35) for those initiating vaccination before age 17, and 46% (IRR = 0.54, 95%CI = 0.46–0.64) and 22% (IRR = 0.78, 95%CI = 0.65–0.93) for those initiating vaccination at ages 17–19, and at ages 20–29, respectively. Vaccine effectiveness against CIN3+ was similar to vaccine effectiveness against CIN2+. Results were robust for both women participating to the organized screening program and for women at prescreening ages. We show high effectiveness of qHPV vaccination on CIN2+ and CIN3+ lesions, with greater effectiveness observed in girls younger at vaccination initiation. Continued monitoring of impact of HPV vaccination in the population is needed in order to evaluate both long‐term vaccine effectiveness and to evaluate whether the vaccination program achieves anticipated effects in prevention of invasive cervical cancer.

    Cervical dysplasia, a premalignant lesion that can progress to cervical cancer, is caused primarily by a sexually transmitted infection with an oncogenic strain of the human papillomavirus (HPV). The HPV infections are treated through destroying the clinical lesions: laser, cryotherapy, podophyllin... The hope is that by causing local tissue inflammation that the body will be stimulated to mount an antibody response and thereby prevent recurrence. In contrast to other prevention approaches, vaccines can reduce susceptibility in uninfected partners by stimulating the immune system. Aloe vera has also been reported to retard tumour growth and stimulate the immune response to viruses. A list of possible actions of propolis includes: antibacterial, antifungal, antiviral, antioxidant, anticarcinogenic, antithrombotic and immunomodulatory. Research on the possible role of some B vitamins in preventing cancer began in the last few decades, but however this complex have an influence on immune status. The aim of our study is to try to treat the HPV infection as confirmed cause of neoplastic transformation with some herbal therapy and interferon and to try define the guidelines in the management of the HPV positive patients. Goal of this paper is to search for evidence of efficacy of any treatment for HPV infection of the cervix mostly in woman with no concomitant CIN. Fifty five woman affected by HPV genital infection were enrolled in the study from September 2005 to April 2006. Patients were classified according to the results of the HPV testing prior and after the therapy. Patients were randomized into two groups: the first group was HPV positive woman treated with other than recommended therapy (n=20), (control group); the second group was pharmacologically treated with intravaginal administration of an interferon and aloe vera-propolis in recommended scheme (n=35) with treatment of the possible fungal or bacterial genital infection prior to the specific therapy.

    Restoration of non-carious cervical lesions (NCCLs) represents a major challenge for resin materials due to the different adhesive properties of the tooth structure, the biomechanical aspects of the cervical area, and the difficulties in the access and isolation of the operative field. Furthermore, NCCLs should be approached with a complete understanding of the role played by the marginal periodontal tissue. Whenever a cervical lesion is associated with a gingival recession, the interplay between restorative dentistry and periodontology is decisive for full esthetic and long-term success. A case report is presented dealing with the treatment of NCCLs associated with multiple gingival recessions using a combined restorative and periodontal treatment with a 12-month follow-up.

    Full Text Available Se presenta un modelo tridimensional de elementos finitos para investigar el efecto producido por las fuerzas de oclusión en la distribución y magnitud del campo tensional sobre un premolar superior. De esta forma, se busca definir cuál es la situación de carga de oclusión más crítica desde el punto de vista tensional sobre el esmalte dental en la zona cervical que pudiese dar origen a una lesión del tipo no cariosa. Utilizando elementos finitos hexaédricos lineales y procesando el modelo con el programa SAMCEF se realiza un análisis numérico estático lineal considerando que el premolar es isótropo y homogéneo. Se definen siete estados de carga asociados a una fuerza de oclusión de 170 N para las cuales se investiga la distribución y magnitud de los campos tensionales sobre el premolar. Los resultados numéricos permiten concluir que las tensiones máximas sobre el premolar tienden a concentrarse en la zona cervical alcanzando sus valores máximos cuando la carga de 170 N actúa de forma inclinada a 45º con respecto a la vertical. La relevancia de la presente investigación radica en el hecho que numéricamente se demuestra que la distribución y zona en donde los campos tensionales tienden a concentrase y alcanzar sus valores máximos son coincidentes con las zonas del diente en donde clínicamente se observan lesiones no cariosas.A three-dimensional model of finite elements in order to investigate the effect produced by occlusion forces on both distribution and magnitude of the tensional field on an upper premolar is hereby presented. Thus, defining from a tensional point of view, which is the situation of the most critical occlusion loading on dental enamel capable to produce a non-cavity lesion is intended. By using finite linear hexahedral elements and processing the models through SAMCEF software, a static linear numerical analysis is performed, considering that premolar is isotropic and homogeneous.

    The aim of the study was to investigate the feasibility and value of clinical application of fine-needle aspiration histological biopsy via ultrasound-guided thyroid nodule and enlarged cervical lymph node fine-needle aspiration histological biopsy. Fine-needle aspiration cytological and histological biopsies and surgical treatments were performed on 982 patients with thyroid nodule and 1435 patients with enlarged cervical lymph nodes. A comparative study of the histological and cytological examination results and post-surgical etiology results was subsequently conducted. Among the 982 thyroid nodule patients, the acquisition rates were 89.8% (882/982) for fine-needle aspiration histological biopsy and 96.2% (945/982) for cytological biopsy, while among the 1435 patients with enlarged cervical lymph nodes, the acquisition rate for fine-needle aspiration cytological biopsy was slightly higher than that for histological biopsy, with values of 95.7% (1374/1435) and 91.4% (1312/1435), respectively. For the thyroid nodule patients, when the acquired histological and cytological biopsy results were compared with the post-surgical etiology results, the sensitivity, specificity, and accuracy of the histological results were 98.5%, 100%, and 98.9%, respectively, whereas those of the cytological results were 86.8%, 82.9%, and 85.6%, respectively; the differences between the 2 biopsy methods were statistically significant (P < 0.05). For the patients with enlarged cervical lymph nodes, when the acquired histological and cytological biopsy results were compared with the post-surgical etiology results, the sensitivity, specificity, and accuracy of the histological results were 96.3%, 99.8%, and 97.6%, respectively, whereas the those of the cytological results were 76.8%, 92.1%, and 82.2%, respectively; again, the differences between the 2 methods were statistically significant (P < 0.05).

One hundred and seventy-four Papanicolaou test smears with cellular changes were examined. MN screening was done in cytopathological smears by counting 1,000 cervical cells in a light microscope. MN frequencies were significantly higher in the group with cellular changes compared to the control group (p < 0.001. The mean MN frequencies were 0.95 ± 1.12 (mean ± SD in the control group (n = 223, 2.98 ± 1.20 in individuals with atypical squamous cells of undetermined significance (ASC-US (n = 50, 4.04 ± 1.45 in cervical intraepithelial neoplasia (CIN I (n = 52, 5.97 ± 1.83 in CIN II (n = 30, 7.29 ± 1.55 in CIN III (n = 17 and 8.64 ± 1.55 in invasive cancer (n = 25. These findings suggest that MN monitoring should be included as an additional criterion for the early detection of cytogenetic damage in routine examinations. This monitoring should be done in the same smear as used for cytopathological examination. More specific and systematic studies are necessary to confirm this proposal.

    2017-03-08

    Non-carious cervical lesions (NCCLs) were examined in 6541 extracted human teeth and classified based on the morphology of the lesions. As a result, NCCLs were found on 38.7% of teeth (41.6% on maxillary teeth and 36.0% on mandibular teeth), and were most frequent on canines and first premolars. According to the new method of classification, the morphology of NCCLs was classified both by the surface contour (SC) and by the cross-sectional contour (CC). Three types of NCCLs appeared to be dominant. The causes of these NCCLs were discussed based on their morphologies, positions where these NCCLs were frequently found, and the results of previous studies. NCCLs with a horizontal oval SC and a round CC (Type I), which were frequent on the labial surfaces of maxillary canines and buccal surfaces of maxillary first premolars, may be associated with wear by friction and chemical degradation. NCCLs with a vertical oval SC and a round CC (Type II), which were frequent on the lingual surfaces of mandibular incisors and canines, might be mainly related to chemical degradation. NCCLs with a horizontal oval SC and a wedge shape CC (Type III), which were extensively found on the buccal surfaces of maxillary premolars, had formed most probably due to wear by friction and microstructural loss by stress. This new method can classify the morphology of NCCLs more precisely and deduce the mechanisms of the formation of NCCLs more clearly than former methods.

    The purpose of this study was to evaluate the chemical bonds of a self-etch 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) adhesive to natural noncarious cervical lesions (NCCLs) and compare them with those occurring in sclerotic dentin in artificially prepared defects (APDs). Four human teeth with natural NCCLs on the buccal surface were selected. Artificial defects matching the natural lesions were prepared on the lingual surface of the same teeth serving as control. Micro-Raman (MR) spectroscopy was used to quantify mineral content in natural NCCLs and in APDs. Fourier transform infrared-photoacoustic spectroscopy (FTIR-PAS) readouts were taken before and after adhesive application to analyze the protein matrix/mineral (M:M) ratio and chemical interactions between 10-MDP adhesive and dentin. The MR and FTIR-PAS spectra collected from natural NCCLs demonstrated a larger area of the band (961 cm(-1), PO4) and lower M:M ratio, respectively, characterizing a hypermineralized dentin, compared with APDs. FTIR-PAS demonstrated emergence of a peak (1179 cm(-1), P=O) in spectra after adhesive treatment, demonstrating a more intense chemical interaction in natural NCCLs. The results demonstrated that chemical bonding of 10-MDP adhesive to natural NCCLs is more intense, due to the hypermineralized surface, and suggest that it is unnecessary to remove the hypermineralized layer with burs, as this may decrease the chemical bonding potential of 10-MDP.

    Full Text Available CONTEXT AND OBJECTIVE: The latest update of the Bethesda System divided the category of atypical squamous cells of undetermined significance (ASCUS into ASC-US (undetermined significance and ASC-H (high-grade intraepithelial lesion cannot be ruled out. The aims here were to measure the prevalence of pre-invasive lesions (cervical intraepithelial neoplasia, CIN II/III and cervical cancer among patients referred to Instituto Fernandes Figueira (IFF with ASC-H cytology, and compare them with ASC-US cases. DESIGN AND SETTING: Cross-sectional study with retrospective data collection, at the IFF Cervical Pathology outpatient clinic. METHODS: ASCUS cases referred to IFF from November 1997 to September 2007 were reviewed according to the 2001 Bethesda System to reach cytological consensus. The resulting ASC-H and ASC-US cases, along with new cases, were analyzed relative to the outcome of interest. The histological diagnosis (or cytocolposcopic follow-up in cases without such diagnosis was taken as the gold standard. RESULTS: The prevalence of CIN II/III in cases with ASC-H cytology was 19.29% (95% confidence interval, CI, 9.05-29.55% and the risk of these lesions was greater among patients with ASC-H than with ASC-US cytology (prevalence ratio, PR, 10.42; 95% CI, 2.39-45.47; P = 0.0000764. Pre-invasive lesions were more frequently found in patients under 50 years of age with ASC-H cytology (PR, 2.67; 95% CI, 0.38-18.83; P = 0.2786998. There were no uterine cervical cancer cases. CONCLUSION: The prevalence of CIN II/III in patients with ASC-H cytology was significantly higher than with ASC-US, and division into ASC diagnostic subcategories had good capacity for discriminating the presence of pre-invasive lesions.

    Full Text Available Abstract Background Human Papillomavirus (HPV is considered as a necessary, but not sufficient, cause of cervical cancer. In this study, we aimed to assess the prevalence of HPV in a series of pre-malignant and malignant cervical lesion cases, to identify the virus genotypes, and to assess their distribution pattern according to lesion type, age range, and other considered variables. The samples were submitted to histopathological revision examination and analysed by polymerase chain reaction (PCR for the presence of HPV DNA, followed by HPV typing by dot blot hybridisation. Findings Of the analysed samples, 53.7% showed pre-malignant cervical lesions, and 46.3% presented with cervical cancer. Most cancer samples (84.1% were classified as invasive carcinoma. The mean age of these cancer patients was 47.3 years. The overall HPV prevalence was 82.4% in patients with pre-malignant lesions and 92.0% in the cancer patients. HPV 16 was the most prevalent type, followed by HPV 18 and 58, including both single and double infections. Double infection was detected in 11.6% of the samples, and the most common combination was HPV 16+18. Conclusions Cervical cancer appears to occur in women in a lower age range in the studied area, compared to the situation in other Brazilian regions. Furthermore, among the patients with CIN 3 and those with cancer, we observed a higher proportion of married women, women with more than one sexual partner, smokers, and individuals with less than an elementary education, relative to their counterparts. Findings The overall HPV prevalence was 82.4% in patients with pre-malignant lesions and 92.0% in the cervical cancer patients from Northeast Brazil. HPV 16 was the most prevalent type, followed by HPV 18 and 58. The most common double infection was HPV 16+18. Cervical cancer appears to occur in women in a lower age range in the Northeast Brazil.

    Using intrinsic fluorescence, diffuse reflectance and light scattering spectroscopy we extracted quantitative biochemical and morphological information in vivo about the bulk tissue and the epithelial cell nuclei of ectocervical sites from 44 patients. Significant changes were observed in tissue morphology and biochemistry between normal, squamous metaplastic and squamous intraepithelial lesion (SIL) sites. The combined use of all three spectroscopic techniques (tri-modal spectroscopy) yielded superior results for detecting SILs than any one of the techniques alone.

  11. p16INK4 expression in precursor lesions of squamous cell cervical cancer related to the presence of HPV-DNA

    Full Text Available The purpose of the present study was to identify the expression of p16INK4 in cervical cancer precursor lesions by immunohistochemistry and to correlate it with lesion grade and presence of human papillomavirus (HPV infection. Cervical specimens from 144 women seen consecutively at the gynecology outpatient clinic of our institution from December 2003 to May 2005 were analyzed by cytopathology, histopathology, polymerase chain reaction for HPV-DNA, and p16INK4 immunostaining. Histologically normal biopsies, HPV-DNA negative by polymerase chain reaction, were used as control. HPV-DNA prevalence, including the control group, was 68.1% and the prevalence of p16INK4 expression was 55.0%. The percentage of cells stained by p16INK4 ranged from 10 to 100%, both in the group consisting of cervical intraepithelial neoplasia (CIN1/HPV specimens and in the group of CIN2/CIN3 specimens with P value of 0.0001. p16INK4 expression was 48.3% in the CIN1/HPV group, as opposed to 94.3% in the CIN2/CIN3 group (P = 0.001, showing a statistically significant difference between the two groups. The quantitative method used here is simple and less subjective than the different semiquantitative methods described in the literature. In view of the different definitions of a p16INK4-positive case, it is almost impossible to compare the findings reported by different investigators. This study confirms the association between p16INK4 and CIN2 and CIN3 lesions. Moreover, it shows that some low grade lesions expressed high levels of this protein. This may indicate that such low grade lesions may be predisposed to progress to high grade lesions. This means that p16INK4 may be a strong marker for "neoplastic lesions" induced by HPV and not just an infection marker.

    Full Text Available Cervical cancer is the third most common form of cancer affecting women especially in third world countries. The predominant reason for such alarming rate of death is primarily due to lack of awareness and proper health care. As they say, prevention is better than cure, a better strategy has to be put in place to screen a large number of women so that an early diagnosis can help in saving their lives. One such strategy is to implement an automated system. For an automated system to function properly a proper set of features have to be extracted so that the cancer cell can be detected efficiently. In this paper we compare the performances of detecting a cancer cell using a single feature versus a combination feature set technique to see which will suit the automated system in terms of higher detection rate. For this each cell is segmented using multiscale morphological watershed segmentation technique and a series of features are extracted. This process is performed on 967 images and the data extracted is subjected to data mining techniques to determine which feature is best for which stage of cancer. The results thus obtained clearly show a higher percentage of success for combination feature set with 100% accurate detection rate.

    We report preliminary results from a multi-center trial of evaluating the performance of a novel, full-field multi-spectral tissue fluorescence imaging system (CerviscanTM) designed to detect cervical squamous intraepithelial lesions. Spectral data from multiple regions of 48 patients enrolled from clinical performance sites in the US and Canada are included in this preliminary analysis. This includes 30 women used for the training set and 18 used for the testing set. In the testing set, 37/43 SIL and 70/80 NonSIL regions were correctly identified for a sensitivity of 86% and specificity of 87.5%. CerviscanTM locates cervical precancerous lesions with high sensitivity and specificity and has the potential to permit 'see and treat' patient management.

    Full Text Available Background Cervical carcinoma is one of the most common causes of mortality among women.Early detection can be done by Papanicolaou (Papsmear test - a simplest, safe, cost effective and non invasive procedure. The main objective of this study was to categorize Pap smears for cytohistologicalexamination as well as clinically correlate to analyze sensitivity, specificity and positive predictive value of Pap smear. Methods In this prospective study 417 Pap smears performed, cytohistological correlation was done in 104 cases because patients had undergone both Pap smear and cervical biopsy.Detailed history was taken and clinical examination was done. Pap smear sample was collected from cervix and reporting was made according to Bethesda 2001 classification.Cytological findings were correlated with histopathology. Results Overall concordance rate was 60.7%. Concordance rate for malignancy was 100%, for inflammatory lesions 70.8% and for cervical intraepithelial neoplasia (CIN 33.3%. Common age group presented for screening was40-50 years.Commonest clinical presentationwas bleeding per vaginum. Conclusion The study provides good cyto-histopathology correlation in detecting high grade lesions and malignancy. Although Pap smear sensitivity was low but can be increased by adequate sampling and avoiding technical errors.Bethesda system is strongly recommended for adequacy of sampling to minimize inconsistency.Regular screening should be advised to the patients for the early detection of cervical carcinoma.

  20. Bulky Early-Stage Cervical Cancer (2-4 cm Lesions): Upfront Radical Trachelectomy or Neoadjuvant Chemotherapy Followed by Fertility-Preserving Surgery: Which Is the Best Option?

    Science.gov (United States)

    Plante, Marie

    2015-05-01

    Radical trachelectomy is now recognized as a valid treatment option for young women with early-stage cervical cancer with lesions measuring less than 2 cm. However, for women with bulky lesions measuring greater than 2 cm, few data are available in the literature to guide management. There are currently 2 options available: either upfront radical trachelectomy or neoadjuvant chemotherapy followed by fertility-preserving surgery. Overall, both options offer very good oncologic outcome; however, the rate of fertility preservation and obstetrical outcome seem superior after neoadjuvant chemotherapy. Advantages and disadvantages of both options are discussed and a thorough literature review is provided. Issues to be further studied are also outlined.

    This study evaluates the prevalence and risk factors of non-carious cervical lesions (NCCLs) in a Brazilian population of workers exposed and non-exposed to acid mists and chemical products. One hundred workers (46 exposed and 54 non-exposed) were evaluated in a Centro de Referência em Saúde do Trabalhador - CEREST (Worker's Health Reference Center). The workers responded to questionnaires regarding their personal information and about alcohol consumption and tobacco use. A clinical examination was conducted to evaluate the presence of NCCLs, according to WHO parameters. Statistical analyses were performed by unconditional logistic regression and multiple linear regression, with the critical level of p smoking (p = 0.01) and age group (p = 0.04). The prevalence of NCCLs in the study population was particularly high (76.84%), and the risk factors for NCCLs were age, exposure to acid mists and smoking habit. Controlling risk factors through preventive and educative measures, allied to the use of personal protective equipment to prevent the occupational exposure to acid mists, may contribute to minimizing the prevalence of NCCLs.

    Full Text Available The objective of the study was to determine the dynamics of precancerous lesions in women of a cohort treated for cervical intraepithelial neoplasia (CIN and followed up over the next two years. The conditional probability of failure was calculated using the Kaplan-Meier method, and the raw and adjusted hazard ratios (HR were determined using Cox regression with a p-value entry of < 0.05. Of the 237 women who were treated, 51.5% were accompanied over 24 months, and treatment failed for 21.9% of those accompanied. Women who had five or more pregnancies (adjusted HR = 3.10, 95%CI: 1.28-7.51 or an initial histological diagnosis of CIN II/III demonstrated an independent risk of treatment failure (adjusted HR = 3.14, 95%CI: 1.20-8.19. Being in a stable relationship was a protective factor against treatment failure (adjusted HR = 0.47, 95%CI: 0.24-0.89. A history of more frequent pregnancies and a histological diagnosis of CIN II/III are directly correlated with risk of CIN treatment failure, whereas being in a stable relationship is inversely correlated with this risk.

    The prevalence and genotype distribution of human papillomavirus (HPV) provides the basis for designing HPV prevention programs. The prevalence rates of type-specific HPV and coinfections in samples of Mexican women were investigated in 822 women aged 18-87 years. HPV detection was performed using a Linear Array™ genotyping test. HPV infection was found in 12.4% of controls, 46.3% of those with cervical intraepithelial neoplasia 1, and 100% of those with cervical intraepithelial neoplasia 3 or cervical cancer. HPV 16 was the most prevalent type in all diagnosis groups. The HPV types most frequently found in cervical cancers were 16, 18, 45, 52, 58, and 39; HPV types 16, 62, 51, 84, 18, 53, and CP6108 were the most prevalent in control women. Considering HPV-positive samples only, coinfections occurred most often in controls (63%) and were less frequent in those with cervical cancer (26%). The most frequent viral types in coinfections with HPV 16 in control women were HPV 62, 51, and 84; in women with cervical cancers, HPV 18, 39, and 70 were most common. In conclusion, in addition to HPV types 16 and 18, types 45, 39, 58, 52, and 71 were found in cervical cancers in Mexican women (78%); among them, only 65% were attributable to HPV types 16 and 18. Therefore, it is necessary to consider these viral types in the design of new vaccines, and to determine whether certain HPV types coinfecting with HPV 16 in precursor lesions determine tumor progression or regression.

    Full Text Available The aim of this study was to examine the prevalence and genetic variability of the capsid L1 gene of rare HPV genotypes that were found in the cervical lesions of women from North-East Brazil. A total number of 263 patients were included in this study. HPV detection was performed using PCR followed by direct sequencing of MY09/11, as well as type-specific PCR to detect the Alpha-9 species. Epitope prediction was performed to determine whether or not the genetic variants are inserted in B-cell and T-cell epitopes. The prevalence of rare HPV types in cervical lesions was found to be 9.47%. The rare HPV genotypes that were detected were HPV-53, 54, 56, 61, 62, 66, 70, and 81. The genetic variability in the L1 gene of rare HPV types involved thirty nucleotide changes, eight of which were detected for the first time in this study. Moreover, some of these variants are embedded in B-cell or T-cell epitope regions. The results of this research suggest that rare HPV types might be involved in cervical lesions and some of these variants can be found in B-cell and T-cell epitopes. Data on the prevalence and variability of rare HPV types will assist in clarifying the role of these viruses in carcinogenesis.

    Full Text Available Human immunodeficiency virus type 1 (HIV-positive pregnant women require specific prophylactic and therapeutic approaches. The efficacy of established approaches is further challenged by co-infection with other sexually transmitted diseases (STDs. The objective of this study was to determine the prevalence of co-infections in pregnant women infected with different HIV-1 subtypes and to relate these findings, together with additional demographic and clinical parameters, to maternal and infant outcomes. Blood samples from pregnant women were collected and tested for syphilis, hepatitis B virus (HBV and hepatitis C virus (HCV. Human papillomavirus (HPV diagnosis was evaluated by the presence of alterations in the cervical epithelium detected through a cytopathological exam. Medical charts provided patient data for the mothers and children. Statistical analyses were conducted with STATA 9.0. We found a prevalence of 10.8% for HCV, 2.3% for chronic HBV, 3.1% for syphilis and 40.8% for HPV. Of those co-infected with HPV, 52.9% presented high-grade intraepithelial lesions or in situ carcinoma. Prematurity, birth weight, Apgar 1' and 5' and Capurro scores were similar between co-infected and non-co-infected women. The presence of other STDs did not impact maternal and concept outcomes. More than half of the patients presenting cervical cytology abnormalities suggestive of HPV had high-grade squamous intraepithelial lesions or cervical cancer, evidencing an alarming rate of these lesions.

    Recently neurologic complications after coronary artery bypass grafting (CABG) have received increasing attention. There is no detailed report about the risk factors for these complications, although stenosis in the cervical and intracranial arteries, especially in Japanese patients, latent ischemic brain lesions and preoperative neurological conditions are related to these events. In this prospective study, we evaluated occlusive lesions in the cervical carotid and intracranial arteries, silent brain infarction and cerebral deep white matter lesion with MRA and MRI in patients scheduled to undergo CABG to determine the prevalence of occlusive diseases in cervical carotid and intracranial arteries, latent ischemic change in the brain in this population and to identify preoperative risk factors for these patients. The subjects were 144 consecutive patients (103 men and 41 women, mean age 65.9{+-}9.2 years old) who were scheduled for CABG under elective conditions and who were examined by the same MRI apparatus using the same protocol between November 1998 and March 2001. After routine neurological examination and Mini-Mental State Examination (MMSE) were completed, MRI and MRA were obtained, then the prevalence of abnormalities on MRI and MRA studies and risk factors were evaluated. Cervical carotid artery stenosis with {>=}50% luminal narrowing was detected in 29.2% of the subjects, and that with {>=}75% luminal narrowing was detected in 16.0% of the subjects. Intracranial arterial stenosis showing {>=}50% luminal narrowing was detected in 38.2% of subjects, and that showing {>=}75% luminal narrowing was detected in 19.4% of subjects. Brain infarction was observed in 74.3% of subjects, cerebral deep white matter lesion showing grade 2 or higher on Fazekas classification was observed in 17.4% of the subjects. The characteristics, including possible risk factors of subjects with and without these abnormal findings, were compared. Patients with cervical carotid

    Full Text Available SUMMARY High-risk human papillomavirus (hr-HPV infection is necessary but not sufficient for cervical cancer development. Recently, P16INK4A gene silencing through hypermethylation has been proposed as an important cofactor in cervical carcinogenesis due to its tumor suppressor function. We aimed to investigate P16INK4A methylation status in normal and neoplastic epithelia and evaluate an association with HPV infection and genotype. This cross-sectional study was performed with 141 cervical samples from patients attending Hospital Moncorvo Filho, Rio de Janeiro. HPV detection and genotyping were performed through PCR and P16INK4A methylation by nested-methylation specific PCR (MSP. HPV frequency was 62.4% (88/141. The most common HPV were HPV16 (37%, HPV18 (16.3% and HPV33/45(15.2%. An upward trend was observed concerning P16INK4A methylation and lesion degree: normal epithelia (10.7%, low grade lesions (22.9%, high grade (57.1% and carcinoma (93.1% (p < 0.0001. A multivariate analysis was performed to evaluate an association between methylation, age, tobacco exposure, HPV infection and genotyping. A correlation was found concerning methylation with HPV infection (p < 0.0001, hr-HPV (p = 0.01, HSIL (p < 0.0007 and malignant lesions (p < 0.0001. Since viral infection and epigenetic alterations are related to cervical carcinoma, we suggest that P16INK4A methylation profile maybe thoroughly investigated as a biomarker to identify patients at risk of cancer.

    Full Text Available Non-carious cervical tooth lesions for many decades were attributed to the effects of abrasion and erosion mainly through toothbrush trauma, abrasive toothpaste, and erosive acids. However, though the above may be involved, more recently a biomechanical theory for the formation of these lesions has arisen, and the term abfraction was coined. The aim of this study was to investigate the biomechanics of abfraction lesions in upper canine teeth under axial and lateral loading conditions using a three-dimensional finite element analysis. An extracted human upper canine tooth was scanned by μCT machine (Skyscan, Belgium. These μCT scans were segmented, reconstructed, and meshed using ScanIP (Simpleware, Exeter, UK to create a three-dimensional finite element model. A 100 N load was applied axially at the incisal edge and laterally at 45° midpalatally to the long axis of the canine tooth. Separately, 200 N axial and non-axial loads were applied simultaneously to the tooth. It was found that stresses were concentrated at the CEJ in all scenarios. Lateral loading produced maximum stresses greater than axial loading, and pulp tissues, however, experienced minimum levels of stresses. This study has contributed towards the understanding of the aetiology of non-carious cervical lesions which is a key in their clinical management.

    Cervical intraepithelial neoplasia 3 (CIN3) is the precursor of mostsquamous carcinomas and serves as a surrogate end point. However, small CIN3 lesions are rarely associated with concurrent invasion. We hypothesized that aggressive follow-up for cytology of atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL) leads predominantly to detection of smaller CIN3 lesions than those usually associated with cancer. We assessed this hypothesis in a masked histopathologic review of 330 CIN3 lesions in the ASCUS LSILTriage Study, focusing on ASCUS referrals. ASCUS referrals underwent randomized management [colposcopy for repeat cytology of high-grade squamous intraepithelial lesion (HSIL), colposcopy for oncogenic human papillomavirus (HPV) detection or repeat HSIL, or immediate colposcopy]; then all were followed with repeat cytology for 2 years, followed by colposcopy and aggressive treatment. We assessed all CIN3 lesions qualitatively and measured 39 of them. CIN3 lesions were overwhelmingly small. Compared with enrollment, lesions found at follow-up or exit involved fewer tissue fragments (P < 0.01) and showed less diffuse gland involvement (P = 0.03). CIN3 lesions found postenrollment after HPV testing involved the fewest tissue fragments [versus immediate colposcopy (P = 0.04) or repeat cytology of HSIL (P = 0.02)], and none showed diffuse gland involvement. The median distal-proximal length was 6.5 mm (median replacement of total epithelium = 5%) in the 39 measured cases. We conclude that CIN3 lesions underlying ASCUS or LSIL generally lack features associated with invasion, particularly if managed using HPV testing, suggesting that aggressive management leads to early detection of CIN3 but probably prevents relatively few cancers in screened populations.

    Full Text Available This study evaluates the prevalence and risk factors of non-carious cervical lesions (NCCLs in a Brazilian population of workers exposed and non-exposed to acid mists and chemical products. One hundred workers (46 exposed and 54 non-exposed were evaluated in a Centro de Referência em Saúde do Trabalhador – CEREST (Worker’s Health Reference Center. The workers responded to questionnaires regarding their personal information and about alcohol consumption and tobacco use. A clinical examination was conducted to evaluate the presence of NCCLs, according to WHO parameters. Statistical analyses were performed by unconditional logistic regression and multiple linear regression, with the critical level of p < 0.05. NCCLs were significantly associated with age groups (18-34, 35-44, 45-68 years. The unconditional logistic regression showed that the presence of NCCLs was better explained by age group (OR = 4.04; CI 95% 1.77-9.22 and occupational exposure to acid mists and chemical products (OR = 3.84; CI 95% 1.10-13.49, whereas the linear multiple regression revealed that NCCLs were better explained by years of smoking (p = 0.01 and age group (p = 0.04. The prevalence of NCCLs in the study population was particularly high (76.84%, and the risk factors for NCCLs were age, exposure to acid mists and smoking habit. Controlling risk factors through preventive and educative measures, allied to the use of personal protective equipment to prevent the occupational exposure to acid mists, may contribute to minimizing the prevalence of NCCLs.

    Full Text Available Background. The aim of this retrospective observational study of women treated for cervical intraepithelial neoplasia grade 2 or worse (CIN2+ was to assess the long-term risk of residual/recurrent high-grade CIN. Materials and Methods. We evaluated 760 women treated by loop electrosurgical excision procedure (684 or conization (76 between 2000 and 2009, and followed up to June 30, 2014 (median follow-up 6.7 years, range 4–14. Visits every 6 months for the first year after treatment and yearly for up to the following 10 years included cytology, colposcopy when indicated, and HPV testing (search and typing. Results. CIN2+ or vaginal intraepithelial neoplasia grade 2 or worse (VAIN2+ was detected in 67 cases (8.8%, 39 at first follow-up and 28 after one/more negative visits. The risk of CIN2+ was higher in case of positive margins (odds ratio (OR 8.04, 95% CI 4.31–15.0, type 3 transformation zone (OR for CIN3 27.7, 95% CI 2.07–36.9, CIN3+ excision (OR 6.02, 95% CI 1.73–20.9, and positive high-risk HPV test at first follow-up (OR for HPV16: 20.6, 95% CI 6.8–62.6; OR for other hrHPV types: 18.3, 95% CI 5.9–57.0. Conclusion. Residual/recurrent high-grade CIN occurred in <9% cases, and the risk was associated with transformation zone type, lesion grade, margins status, and hrHPV test result at 6–12 months of follow-up.

    This study investigated the prevalence, risk factors and association of occlusive wear with non-carious cervical lesions (NCCLs) in the general Chinese population. A total of 1320 subjects were recruited, and multistage and random sampling methods of survey spots were performed. All age groups comprised similar numbers of participants and equal numbers of males and females. Each subject completed a structured interview, and all teeth of each subject were examined by a practitioner to determine NCCLs and occlusive wear. Binary logistic regression was conducted by analysing the association of risk factors with the occurrence of NCCLs. Bivariate correlation analysis was performed by determining the association of NCCLs dimension or depth with the range of occlusive wear facets. Clinical assessment showed that the overall prevalence of subjects diagnosed with NCCLs was 63%. The proportion of subjects or teeth with NCCLs significantly increased with age. Pre-molars were the most commonly affected teeth. Single variables and interactive effects of variables associated with the occurrence of NCCLs include the following: age group, intensity of toothbrushing, frequency of fresh fruit consumption and interactive effect between intensity of toothbrushing and frequency of fresh fruit consumption. A weak positive correlation of the grading index was found between NCCLs dimension, size or depth and range of occlusive wear facets. This study reported the higher prevalence of NCCLs in the general Chinese population. Implementation of a combined strategy to reduce risk factors of NCCLs could be more effective than individual techniques; meanwhile, the occurrence of NCCL could be related to the wear degree of occlusive defects in the population studied.

    The p16(INK4a) is a cyclin-dependent kinase inhibitor that decelerates the cell cycle by inactivating the cyclin-dependent kinases involved in the phosphorylation of the retinoblastoma protein (RB). Expression of E6 and E7 oncogenes of high-risk (HR) human papillomavirus (HPV), affecting the RB-p16 pathway, leads to p16 upregulation. Although it is widely reported that p16 is overexpressed in a high percentage of preneoplastic lesions and in almost all carcinomas of the uterine cervix, protein upregulation and its correlation with HPV infection in low-grade lesions is still being debated. In this study, we investigated in parallel, p16 expression and HPV infection in 100 cervical biopsies (17 normal tissues, 54 CIN1, 10 CIN2, 11 CIN3, eight invasive squamous cancers). Results obtained demonstrated that none of the 17 normal cervical tissues, evaluated by immunohistochemistry, presented p16 positivity whereas, starting from CIN1 (31%) to CIN2 (90%), CIN3 (100%) and carcinomas (100%), a constant and significant increase of protein overexpression (P<0.0001) was observed. In addition, p16 overexpression consistently showed elevated sensitivity (84%) and specificity (98%) in detecting HR-HPV infection with a high positive predictive value (97%) and negative predictive value (86%). Of interest, 93% of the p16-positive CIN1 were also HR-HPV infected. Our findings confirmed that p16 overexpression is associated to high-grade precancerous lesions and cervical carcinomas, and further demonstrated that immunohistochemical evaluation of p16 may be a useful biomarker in identifying HR-HPV-infected low-grade lesions.

    Studies evaluating the routine Papanicolaou (Pap) test have traditionally used as the reference gold standard, the diagnoses on the follow-up histologic samples. Since the latter are typically obtained days to weeks after the Pap test, the accuracy of the resultant comparison may be affected by interim factors, such as regression of human papillomavirus, new lesion acquisitions or colposcopy-associated variability. A subset of our clinicians have routinely obtained cervical cytology samples immediately prior to their colposcopic procedures, which presented a unique opportunity to re-evaluate the test performance of liquid-based cervical cytology in detecting the most clinically significant lesions (i.e. cervical intraepithelial neoplasia 2 or worse: CIN2+), using as gold standard, diagnoses on cervical biopsies that were essentially obtained simultaneously. For each patient, cytohistologic non-correlation between the Pap test and biopsy was considered to be present when either modality displayed a high-grade squamous intraepithelial lesion (HGSIL)/CIN2+ while the other displayed a less severe lesion. Therefore, HGSIL/CIN2+ was present in both the Pap test and biopsy in true positives, and absent in both modalities in true negatives. In false positives, the Pap test showed HGSIL while the biopsy showed less than a CIN2+. In false negatives, Pap tests displaying less than a HGSIL were associated with biopsies displaying CIN2+. Combinations associated with "atypical" interpretations were excluded. A cytohistologic non-correlation was present in 17 (4.8%) of the 356 combinations reviewed. The non-correlation was attributed, by virtue of having the less severe interpretation, to the Pap test in all 17 cases. There were 17, 322, 0, and 17 true positives, true negatives, false positives and false negatives respectively. The sensitivity, specificity, positive predictive value and negative predictive value of the Pap test, at a diagnostic threshold of HGSIL, in identifying

    Treatment of gingival recessions has become one of the most challenging procedures in periodontal plastic surgery. Various surgical options with predictable outcomes are available, but in cases with cervical lesions or restorations, optimal functional and esthetic results may require the combination of periodontal and restorative procedures. In this case report, one patient treated with acellular dermal matrix allograft and a coronally positioned flap in combination with compomer cervical restorations is presented. Clinical parameters were recorded immediately prior to surgery and after 12 months. Postoperatively, significant root coverage, reductions in probing depths, and gains in clinical attachment were observed. The final clinical results, esthetics, color match, and tissue contours were acceptable to both the patient and clinicians.

    BACKGROUND This study aimed to examine the positive and negative predictive value in the diagnosis of premalignant and malignant lesions of cervical colposcopy, the sensitivity and specificity of smear, and to evaluate the correlation with histopathology of abnormal cytology and colposcopy. MATERIAL AND METHODS The criteria for inclusion of patients with unhealthy cervix in the study were: Erosion, Chronic cervicitis, and Healed lacerations, Hypertrophied cervix, bleeding on touch, suspicious growth/ulcer/polyp on the cervix, and abnormal discharges from the cervix. Women with frank carcinoma cervix, pregnant females, patients with bleeding per vaginum at the time of examination, and those who had used vaginal medications, vaginal contraceptives or douches in the last 48 h of examination were excluded from the study. Demographic analysis was performed for 450 patients who were admitted to the clinic. Sensitivity, specificity, positive predictive value and negative predictive values of patients to identify cervical pathologies of smear and colposcopy were histopathologically calculated. The statistical software package SPSS 15.0 (SPSS Inc., Chicago, IL, USA) and Spearman's and Chi-Square tests were used for statistical analysis. RESULTS Sensitivity, specificity, PPD and NDP of smear were 0.57%, 0.76%, 0.26%, 0.92% respectively. Sensitivity, specificity, PPD and NDP of colposcopy were 0.92%, 0.67%, 0.52%, 0.96% respectively. A statistically significant correlation was found between abnormal cytology and histopathology, and abnormal colposcopy finding and histopathology. CONCLUSIONS Women with clinical diagnosis of unhealthy cervix should be evaluated by cytology to detect any premalignant or malignant lesions. It was concluded that Pap smear, colposcopy and histopathology should be collectively evaluated to evaluate cervical findings in low socio-economic regions.

    Full Text Available The previous studies reported some information about prevalence release of high-risk HPV types in HSIL or cervical cancer globally and in Iran, however, this information is not enough for final judgment about vaccination against HPV or any screening program. The aim of the present study was to assess the HPV type distribution in HSIL and ICC specimens of women attending Shahid Beheshti University of Medical Sciences teaching hospitals, Tehran, Iran for treatment during 10 years.This retrospective- descriptive study evaluated the HPV type distribution of pathologic specimens of Iranian women with invasive cervical cancer (ICC and high-grade squamous cell intraepithelial lesions (HSIL. Formalin-fixed tumor biopsies that were retrieved from women presenting with histological confirmation for ICC and 17 pathologic confirmation for HSIL specimens.The most frequently identified HPV type 16 among both groups, women with invasive cervical cancer (4-2.18% and women with High Grade Squamous Intraepithelial Lesion (29.41%, followed by HPV18, HPV31 and 26. HPV16 and / or 18 accounted for 82.2% of all infected samples.The dominance of HPV16 over other high-risk types might be even higher than in a region with low HPV exposure. However, there was no strong evidence for any judgment that show to the policy makers; which one is cost-effectiveness and feasibility for cervical cancer prevention in Iran, vaccination, screening or both? More population based study and national meta-analysis needed for better understanding of HPV prevalence and HPV DNA patterns in Iran.

    Objective To evaluate the expressions of biomarkers p16 and Ki-67 in low-grade (LG) or high-grade (HG) lesions, and to relate them to risk factors and the recurrence of these lesions. Methods A retrospective case-control study of 86 patients with LG and HG lesions who underwent a loop electrosurgical excision procedure (LEEP) between 1999 and 2004. The control group was composed of 69 women with no recurrence, and the study group, of 17 patients with recurrence. All patients were followed-up over a two-year period after surgery, and screened every six months, including cytology and colposcopy. Biopsy samples collected from LEEP were submitted to immunohistochemical analysis for p16 and Ki-67. The statistical analysis was performed using the Statistical Package for the Social Sciences software (SPSS, IBM-SPSS, Inc., Chicago, IL, US), with a significant p ​​p16 and Ki-67, separately or combined, showed no relation to recurrence on the total analysis. However, evaluating specifically HG lesions, the positive expression (2+ and 3+) of p16/Ki-67 was associated with recurrence (0.010). In addition, p16 isolated was also more expressive in HG lesions (2+ and 3 + , p = 0.018), but it was unrelated to recurrence. Conclusion Proteins p16 and Ki-67, both isolated and combined, are not reliable primary markers for the recurrence of cervical lesions in the majority of LG lesions. However, analyzing only the group with prior diagnosis of HG lesions, the expressions of p16 and of p16/Ki-67 were associated with recurrence, and they may be useful in monitoring these cases.

    The Authors have correlated 39 cervical diagnostic biopsies for squamous intraepithelial lesions (SILs) with correspective Papanicolau smears (PS), with relation to the presence or the absence of HPV of oncogenic type (HPV-one) detected by in situ hybridization (ISH). Agreement between cytological and histological diagnosis was present in 14 of 16 cases with detectable HPV-one and only in 12 of 23 cases without detectable HPV-one at ISH. The importance of the HPV type in the SILs with relation to the diagnostic accuracy of Papanicolaou smears has been discussed.

Method: We subjected plasma DNA isolates from 112 patients (CIN and ICC to a pre-PCR restoration treatment to improve detection sensitivity. HPV-specific sequences were detected by conventional PCR both in cervical scrapes and plasma DNA obtained from each patient. For every single DNA sample, both non-restored and restored isolates were PCR analyzed. Results: We detected HPV in plasma DNA isolates with significantly higher efficiency on restored plasma-DNA as compared to each non-restored equivalent, still maintaining close correlation with the clinical stage of the cases. By analyzing plasma-DNA isolates we could classify as HPV positive >50.0% of the cases that were previously known to be positive from the cervical scrape based assay. Interestingly, 100% of the cases in which subtype HPV18 was detected in cervical scrapes were also positive in plasma DNA. Conclusions: Restoration of plasma DNA from cervical cancer patients allows a more sensitive PCR-based HPV detection, maintaining the correlation to disease stage traditionally observed.

    Full Text Available Objective: To establish if measurements of DNA ploidy could be used to assist cytopathologists and cytotechnologists in population based cervical cancer screening programs in countries where manually reading the slides is impossible due to the lack of sufficient skilled cytotechnologists. The goal of such program is to identify only clinically significant lesions, i.e. those where a clinical intervention to remove the lesion is required immediately. Study Design: A total of 9905 women were enrolled in the study. Cervical samples were taken with a cervix brush that was then placed into a fixative solution. The cells were separated from mucus by mechanical and chemical treatment and then deposited onto microscope slides by a cytocentrifuge. Two slides were prepared from each case; one slide was stained by Papanicolaou stain for manual cytology examination, while the other slide was stained by a DNA specific stain. The latter slide was used to determine the relative amount of DNA in the cell nuclei. Results: A total of 876 women were followed by colposcopy examination where biopsies were taken from the visible lesions or from suspicious areas and histopathology diagnosed 459 as normal or benign cases, 325 as CIN1, 36 as CIN2, 25 as CIN3/CIS, and 31 as invasive cancer. Of these 876 cases, manual cytology called 655 normal or ASCUS, 197 as LSIL, 16 cases as HSIL, and 8 as cancer. DNA measurements found 704 cases having no cells with DNA greater than 5c, 98 cases where there were 1 or 2 cells having DNA amount greater than 5c, and 74 cases where there were 3 or more cells having DNA amount greater than 5c. If manual cytology were to be used to refer all cases of HSIL and cancer to colposcopy and biopsy, 23 lesions that had to be removed would have been discovered (2 CIN2, 11 CIN3/CIS, and 10 cancers, for a sensitivity of 25.0±5.2% at specificity of 99.9±0.1%. If DNA assisted cytology were to be used instead, and all cases having 3 or more cells with

    AbstractBackgroundCervical squamous intra-epithelial lesions (SIL) are more frequent in HIV-positive women overall. However the appropriate age at which to begin and end cervical cancer screening for early detection of lesions in HIV-positive women is not clear. We assessed the age-specific prevalence of any SIL and SIL requiring colposcopy in HIV-positive women in Cameroon.MethodsWe enrolled, interviewed and conducted conventional cervical cytology in 282 women, aged 19--68 years, initiating antiretroviral therapy in three clinics in Cameroon. In bivariable analyses, the crude relationship between age and the presence of lesions was assessed using locally weighted regression (LOWESS) methods. In multivariate analyses, generalized linear models with prevalence as the outcome, an identity link and a binomial distribution, were used to estimate prevalence differences. Bias analyses were conducted to assess the potential effect of inaccuracies in cytology.ResultsSIL were detected in 43.5% of the 276 women with satisfactory samples, 17.8% of whom had ASC-H\\/HSIL. On average, women aged 26 to 59 tended to have a slightly higher prevalence of any SIL than other women (Prevalence difference PD: 6.5%; 95%CI: -11.4, 24.4%). This PD was a function of CD4 count (heterogeneity test p-value =0.09): amongst patients with CD4 counts less than 200cells\\/uL, the prevalence was higher in patients aged 26--59, while there was essentially no difference amongst women with CD4 counts greater than 200 cells\\/uL. ASC-H\\/HSIL were present in women as young as 19 and as old as 62. Overall the prevalence of ASC-H\\/HSIL increased by 0.7% (95%CI: -3.8%, 5.1%) per decade increase in age.ConclusionBoth severe and less severe lesions were prevalent at all ages suggesting little utility of age-targeted screening among HIV-positive women. Nevertheless, the long-term evolution of these lesions needs to be assessed in prospective studies.

    Skull vibration induces nystagmus in unilateral vestibular lesion (UVL) patients. Vibration of skull, posterior cervical muscles or inferior limb muscles alters posture in recent UVL patients. This study aimed to investigate the postural effect of vibration in chronic compensated UVL patients. Vibration was applied successively to vertex, each mastoid, each side of posterior cervical muscles and of triceps surae in 12 UVL patients and 9 healthy subjects. Eye movements were recorded with videonystagmography. Postural control was evaluated in eyes open (EO) and eyes closed (EC) conditions. Sway area, sway path, anteroposterior and medio-lateral sways were recorded.A vibration induced nystagmus (VIN) beating toward the healthy side was obtained for each UVL patient during mastoid vibration. In EO, only sway path was higher in UVL group during vibration of mastoids and posterior cervical muscles.The EO postural impairments of UVL patients could be related to the eye movements or VIN, leading to visual perturbations, or to a proprioceptive error signal, providing an erroneous representation of head position. The vibration-induced sway was too small to be clinically useful. Vestibulo-ocular reflex observed with videonystagmography during mastoid vibration seems more relevant to reveal chronic UVL than vestibulo-spinal reflex observed with posturography.

    2009-05-01

    A recent audit at our institution revealed a higher number of cases diagnosed as endocervical glandular neoplasia on ThinPrep (TP) cervical cytology samples (9 cases) as opposed to SurePath (SP) (1 case), which on histology showed only high-grade cervical intraepithelial neoplasia (CIN) with endocervical crypt involvement (CI). We attempted to ascertain the reasons for this finding by reviewing the available slides of these cases, as well as slides of cases diagnosed as glandular neoplasia on cytology and histology; cases diagnosed as high-grade squamous intraepithelial lesions (HSIL) on cytology which had CIN with CI on histology and cases with mixed glandular and squamous abnormalities diagnosed both cytologically and histologically. Single neoplastic glandular cells and short pseudostratified strips were more prevalent in SP than TP with the cell clusters in glandular neoplasia 3-4 cells thick, in contrast to the dense crowded centre of cell groups in HSIL with CI. The cells at the periphery of groups can be misleading. Cases with HSIL and glandular neoplasia have a combination of the features of each entity in isolation. The diagnosis of glandular neoplasia remains challenging and conversion from conventional to liquid based cervical cytology requires a period of learning and adaptation, which can be facilitated by local audit and review of the cytology slides in cases with a cytology-histology mismatch.

    Cervical cancer seriously endangers women′s health,and human papillomavirus (HPV) is considered to be the primary cause. Doctors have been striving to find an effective diagnostic method for judging cervical lesions level and predicting its prognosis. HPV capsid proteins comprise the major capsid protein (L1 capsid protein) and the minor capsid protein (L2 capsid protein),and these two proteins play an important role in assembling into virus particles,trafficking HPV to the cell,and causing the host′s immune reactions. In recent years,studies have shown that the L1 capsid protein can be used to predict the progress and subsidence of cervical lesions. HPV prophylactic vaccines ,which are exploited on the basis of the L1 and L2 capsid protein,are proved to get a good preventive effect in clinical trials. This paper reviews the biological characteristics of HPV and researches progress on HPV capsid protein in cervical lesions in recent years.%宫颈癌严重危害妇女健康,人乳头瘤病毒(HPV)感染是其首要病因。临床医师一直致力于寻找一种能有效判断宫颈病变级别及预测预后的诊断方法。 HPV衣壳蛋白包括主要衣壳蛋白(L1壳蛋白)和次要衣壳蛋白(L2壳蛋白),这两种蛋白在组装成病毒颗粒、协助病毒入胞及引起机体免疫反应等多个方面发挥重要作用。近年研究表明, L1壳蛋白可用于预测宫颈病变的进展与消退。以L1及L2壳蛋白为基础研发的HPV预防性疫苗在临床试验中得到了很好的预防效果。综述HPV生物学特点及近年来有关HPV衣壳蛋白在宫颈病变的研究进展。

    The aim of this study was to evaluate the impact of the surgical excisional procedures for cervical intraepithelial neoplasia (CIN) treatment both on subsequent fertility (cervical factor) and pregnancy complication (risk of spontaneous preterm delivery). We retrospectively analyzed 236 fertile women who underwent conization for CIN. We included in the study 47 patients who carried on pregnancy and delivered a viable fetus. Patients were asked about postconization pregnancies, obstetrical outcomes, and a possible diagnosis of secondary infertility caused by cervical stenosis. We evaluated the depth of surgical excision, the timing between cervical conization and subsequent pregnancies, surgical technique, and maternal age at delivery. We recorded 47 deliveries, 10 cases of preterm delivery; 8 of them were spontaneous. The depth of surgical excision showed a statistically significant inverse correlation with gestational age at birth. The risk of spontaneous preterm delivery increased when conization depth exceeded a cut-off value of 1.5 cm. Our data do not demonstrated a relation between conization and infertility due to cervical stenosis. PMID:24324288

    Full Text Available Abstract Background Previous studies have either investigated the relationship of HPV with oral cancer or the prevalence of HPV on the oral cavity. The purpose of this investigation was to study the prevalence of HPV in oral cavity of women with oral sex practices and cervical lesions. Methods Forty six (46 non-smokers and non-alcoholic patients attended the "Clínica de Displasias" of "Ciudad Juarez" were sampled. This population had a CIN diagnosis sometime between the previous six months. On previous consent they filled out a questionnaire related to their oral sex practices. Afterwards one swab from cheeks and another from palate/gum were taken; PCR was used to determine generic HPV, HPV16 and HPV18. Results Seventy two percent (72% of the patients stated to have oral sex practices regularly which all of them were positive to HPV either in oral mucus, palate/gum or both. The total of the given results showed that 35% had HPV16; among those distributed in 26% with regular oral sex practices and 9% stated as never practiced oral sex. An association was found between oral HPV16 positivity and progression to cervical CIN advanced lesions. On the other hand HPV18 was not detected. The frequency of HPV16 was higher in buccal mucosa (23% versus palate/gum (16%. Conclusions This study suggests that buccal HPV16 infection is associated with CIN progression.

    The link between high-risk human Papillomavirus (HR-HPV) and other sexually transmitted diseases (STDs) in the risk of developing cervical cancer still unclear. Thus, in this report we investigated the rates of co-infections between HPV and other important non-HPV STDs in different cervical findings using a multiplex polymerase chain reaction (M-PCR) to simultaneously detect Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, HSV-1 and -2, and Treponema pallidum. A total of 838 women aged 18 to 68 years were screened using Papanicolaou smears for cervical abnormalities, HPV and non-HPV STDs using PCR and M-PCR methods. A total of 614 (73.3%) of the women had normal cytology (NILM) and 224 (26.7%) women exhibited abnormal cytology (≥ ASC-US). HPV-DNA prevalence was 33.9%, and HPV-16 was the most prevalent genotype in women with NILM and ≥ ASC-US cytology. Non-HPV STDs were detected in 30.4% women and T. vaginalis was the most prevalent one (11.6%). A higher increased risk of ≥ ASC-US and HSIL occurred in co-infections of HR-HPV with C. trachomatis and N. gonorrhoeae. Co-infections of HPV-DNA and HR-HPV with HSV-2 exhibited a similar increased risk but only with ≥ ASC-US. Co-infections of HPV-DNA and HR-HPV with T. vaginalis demonstrated a similar increased risk of ≥ ASC-US and HSIL. We found that C. trachomatis and N. gonorrhoeae were the primary pathogens associated with HR-HPV for the increased risk for all grades of cervical abnormalities but mainly for HSIL, suggesting a possible synergistic action in cervical lesions progression. Our results reinforce the hypothesis that some non-HPV STDs might play a role as co-factors in HPV-mediated cervical carcinogenesis. These data improve our understanding of the etiology of SCC and may also be useful for disease prevention. PMID:27429850

    Full Text Available Abstract Background Immunological alterations are implicated in the increased prevalence of high-grade squamous intraepithelial lesions (HG-SIL and persistent human papillomavirus (HPV infection. This study evaluated the expression of CD4, CD8, CD25 (IL-2Rα and CD28 antigens from SIL biopsies, stratified by HIV status and HPV-type. Biopsies specimens from 82 (35 HIV+ women with a normal cervix, low-grade (LG-SIL or high-grade lesions (HG-SIL were studied. CD molecule expression was evaluated by immunohistochemistry and HPV detection/typing performed using PCR techniques. Results CD4 stromal staining was increased in patients with HPV18. Women with HPV16 infection showed decreased: a CD8 and CD25 stromal staining, b CD25 staining in LG-SIL epithelium and in HG-SIL stroma. In HIV- women samples, CD28 epithelial staining and CD8 stromal staining surrounding metaplastic epithelium were less intense and even absent, as compared to HIV+ women. Both epithelial and stromal CD8 staining was more intense in the HG-SIL/HIV+ group than in the HG-SIL/HIV- group. Positive correlations were observed between CD4/CD25, CD4/CD28 and CD25/CD28 in the stroma and CD25/CD28 in the epithelium. Conclusion HIV status and HPV-type may influence the lymphomononuclear cell profile present in the spectrum of cervical lesions. The knowledge of the infiltrating cell profile in cervical tumours may help the development of specific anti-tumoural strategies.

    Full Text Available Squamous cervical carcinoma (SCC is the most common cancer found in Mexican women. Human papillomavirus (HPV infection is a prerequisite for this disease. In Mexico little is known about the prevalence of HPV-types and knowledge of the circulating genotypes by region is limited. The aim of this study was to determine the prevalence and genotypes of HPV in biopsies from women with intraepithelial lesions and SCC. A total of 211 cervical biopsies were studied. Histopathological analysis was done and HPV DNA was detected by PCR using MY09/MY11 (MY-PCR and GP5+/GP6+ (GP+PCR primers. Viral type was determined by RFLP’s or sequencing. Tissues were classified as low-grade squamous intraepithelial lesion (LSIL in 123 cases, high-grade squamous intraepithelial lesion (HSL in 40 and SCC in 48. Prevalence of HPV was 55.3% in LSIL, 65% in HSIL and 91.7% in SCC by MY-PCR. These percentages increased to 83, 77.5 and 100%, respectively, when HPV-negative samples were analyzed by GP+PCR. In 138 of 211 samples (65.4%, HPV was detected by MY-PCR and 43 (20.4% were positive by GP+PCR. In 166 (91.7% of 181 infections high risk HPV-types were found. Twelve genotypes were detected (16, 18, 31, 33, 45, 52, 58, 59, 61, 66, 70, 81. Prevalence of HPV 16 in LSIL, HSIL and SCC, were 70.6, 54.8 and 70.8%, respectively and it was the most common type in all cases (67.9%. A significantly higher number of positive samples were detected with MY-PCR and GP+PCR. The high prevalence of HPV infection with high-risk types, especially HPV16, among Mexican women with SIL and SCC, has important implications in the treatment and prophylaxis.

    Our objective was to evaluate the progression and regression of cervical dysplasia in human immunodeficiency virus (HIV)-positive women during the late antiretroviral era. Risk factors as well as outcomes after treatment of cancerous or precancerous lesions were examined. This is a longitudinal retrospective review of cervical Pap tests performed on HIV-infected women with an intact cervix between 2004 and 2011. Subjects needed over two Pap tests for at least 2 years of follow-up. Progression was defined as those who developed a squamous intraepithelial lesion (SIL), atypical glandular cells (AGC), had low-grade SIL (LSIL) followed by atypical squamous cells-cannot exclude high-grade SIL (ASC-H) or high-grade SIL (HSIL), or cancer. Regression was defined as an initial SIL with two or more subsequent normal Pap tests. Persistence was defined as having an SIL without progression or regression. High-risk human papillomavirus (HPV) testing started in 2006 on atypical squamous cells of undetermined significance (ASCUS) Pap tests. AGC at enrollment were excluded from progression analysis. Of 1,445 screened, 383 patients had over two Pap tests for a 2-year period. Of those, 309 had an intact cervix. The median age was 40 years and CD4+ cell count was 277 cells/mL. Four had AGC at enrollment. A quarter had persistently normal Pap tests, 64 (31%) regressed, and 50 (24%) progressed. Four developed cancer. The only risk factor associated with progression was CD4 count. In those with treated lesions, 24 (59%) had negative Pap tests at the end of follow-up. More studies are needed to evaluate follow-up strategies of LSIL patients, potentially combined with HPV testing. Guidelines for HIV-seropositive women who are in care, have improved CD4, and have persistently negative Pap tests could likely lengthen the follow-up interval.

    Human papillomavirus (HPV) is widely known as a cause of cervical cancer (CC) and cervical intraepithelial neoplasia (CIN). HPVs related to cancer express two main oncogenes, i.e. E6 and E7, considered as tumorigenic genes; their integration into the host genome results in the abnormal regulation of cell cycle control. Due to their peculiarities, these oncogenes represent an excellent target for cancer immunotherapy. In this work the authors highlight the potential use of therapeutic vaccines as safe and effective pharmacological tools in cervical disease, focusing on vaccines that have reached the clinical trial phase. Many therapeutic HPV vaccines have been tested in clinical trials with promising results. Adoptive T-cell therapy showed clinical activity in a phase II trial involving advanced CC patients. A phase II randomized trial showed clinical activity of a nucleic acid-based vaccine in HPV16 or HPV18 positive CIN. Several trials involving peptide-protein-based vaccines and live-vector based vaccines demonstrated that these approaches are effective in CIN as well as in advanced CC patients. HPV therapeutic vaccines must be regarded as a therapeutic option in cervical disease. The synergic combination of HPV therapeutic vaccines with radiotherapy, chemotherapy, immunomodulators or immune checkpoint inhibitors opens a new and interesting scenario in this disease.

    Cervical cancer is an issue of foremost importance globally, specifically affecting the developing nations. Significant advances have taken place with regard to diagnosis of cervical cancer, especially with screening. Appropriate screening measures can thus reduce the incidence of cervical cancer. The most desirable screening technique should be less invasive, easy to perform, cost-effective and cover a wide range of diagnostic icons. Manual liquid based cytology (MLBC) can be considered as one of the suitable technique for screening with the above-mentioned benefits. The aim of the current study was to compare two cervical screening techniques on the basis of different morphological parameters and staining parameters by using modified acetic acid Pap staining to see the possibility of reducing time economy involved in conventional Pap staining (CPS). The study was conducted on a total 88 cases and all were analyzed with both MLBC and CPS. Forty eight cases that were regarded as satisfactory on the basis of Bethesda system by both methods were further recruited for investigation. Their morphological parameters and staining quality were compared and scored according to a scoring system defined in the study. Quality indices was calculated for both staining procedures and smear techniques.

    Full Text Available As a contribution to the public health authorities in planning prophylactic and therapeutic vaccine strategies, we describe the prevalence of human papillomavirus (HPV types in women presenting abnormal cytological results in Pap smear screening tests in the Federal District, Central Brazil. We studied 129 cervical scraping samples from women whose cytological tests showed either pre-neoplastic or neoplastic lesions. Amplification of HPV DNA was performed by polymerase chain reaction using consensus primers MY09 and MY11 followed by identification of isolates by restriction fragment length polymorphism. We detected HPV DNA in 62% of the samples, including HPV-16 in 43.8%, HPV-58 in 12.5%, HPV-31 in 10%, HPV-53 in 6.3%, each of HPV-18 and HPV-33 in 3.8% of the isolates. Other types (HPV-35, -52, -66, -CP8304, -6, -11, and -CP8061 were less frequent (= or < 2.5% each. The prevalence of HPV-58 was relatively higher in this population than in data in South America, but similar to results obtained in other studies in Latin America, Europe, and Eastern Asia. Case-control studies need to be carried out to establish the association between the prevalence of HPV types specially the less frequent high-risk types and cervical cancer.

    The aim of this study was to investigate the capacity of an HPV16 E6/E7 synthetic overlapping long-peptide vaccine to stimulate the HPV16-specific T-cell response, to enhance the infiltration of HPV16-specific type 1 T cells into the lesions of patients with HPV16+ high-grade cervical squamous intraepithelial lesion (HSIL) and HPV clearance. This was a placebo-controlled randomized phase II study in patients with HPV16-positive HSIL. HPV16-specific T-cell responses were determined pre- and post-vaccination by ELISPOT, proliferation assay and cytokine assays in PBMC and HSIL-infiltrating lymphocytes, and delayed-type hypersensitivity skin tests. Motivational problems of this patient group to postpone treatment of their premalignant lesions affected the inclusion rates and caused the study to stop prematurely. Of the accrued patients, 4 received a placebo and 5 received 1-2 vaccinations. Side effects mainly were flu-like symptoms and injection site reactions. A strong HPV-specific IFNγ-associated T-cell response was detected by ELISPOT in all vaccinated patients. The outcome of the skin tests correlated well with the ELISPOT analysis. The cytokine profile associated with HPV16-specific proliferation varied from robust type 1 to dominant type 2 responses. No conclusions could be drawn on vaccine-enhanced T-cell infiltration of the lesion, and there was no HPV clearance at the time of LEEP excision. Thus, vaccination of HSIL patients results in increased HPV16-specific T-cell immunity. Further development of this type of treatment relies on the ability to motivate patients and in the reduction in the side effects.

    Objective: To explore an ideal approach for detecting the physical status of HPV-16 in clinic use and to investigate the integrated HPV-16 in CINs and cervical cancer. Methods: Multiplex real-time PCR method was established to quantify the copy numbers of E2 and E6 genes (E2/E6) for analysis of the physical status of H PV-16 DNA and this assay was compared to Southern blot analysis. HPV-16-containing paraffin-embedded tissues including 49 CINs and 51 cervical squamous cancers were detected using the method. Results: (1) The cutoff ratio of E2/E6 to distinguish pure episomal from mixed H PV-16, was0.81 in the multiplex real-time PCR; (2) The agreement rate between multiplex real-time PCR and Southern blot was 81.5%(the Kappa statistic was 0.844, P<0.001); (3) HPV-16 DNA existed in an episomal form in 57.1% and mixed form in 42.9%of CIN Ⅰ lesions; The concomitant form of HPV-16 (>70%) constituted the majority in CIN Ⅱ and CIN Ⅲ; HPV-16 DNA mostly integrated into the host chromosome (s) in squamous cervical cancers (68.6%); (4) The incidence of HPV-16 integration was increased with the degree of cervical lesions; (5) The frequency of pure integrated HPV-16 in stage Ⅱ+Ⅲ (88%) was significantly higher than that in stage Ⅰ (33.3%). Conclusion: (1) Mutiplex real-time PCR provides a rapid, sensitive and reliable method for clinic detection of the physical state of HPV-16 DNA; (2) The integration of the HPV-16 DNA is a very early and important event in the progression from preinvasive to invasive cervical cancer; (3) The pure integrated status of HPV-16 in cervical cancer may be associated with poor prognosis of cervical cancer, but further study will be needed to prove its prognostic significance.

    The aim of this study was to assess the clinical performance of a resin-modified glass-ionomer cement (Vitremer) and two polyacid-modified resin composites (F2000 and Freedom) over 1 year. Nineteen patients with at least three cervical lesions were selected, providing an initial sample size of 87 restorations (29 per material), being 78 to non-carious and nine to carious lesions. Restorations were evaluated at baseline, 6 months and 1 year after placement, using modified US Public Health Service criteria: colour match, marginal discoloration, caries, anatomical form, marginal integrity and surface texture. At baseline, restorations were considered as acceptable for all criteria. At 1-year recall, 21 restorations per material were re-examined. Freedom was rated Bravo or Charlie for all the examined criteria and Vitremer earned an Alfa rating solely for the criterion caries. On the contrary, F2000 showed the best overall results, although presenting significant alteration in colour match. Statistical analysis of data was performed using chi-square and Mc Nemar tests. As to the evaluated periods, significant difference was observed solely between baseline and 1-year recall. Freedom and Vitremer were statistically different (P < 0.01) as to anatomical form and surface texture. For F2000, significant difference (P < 0.05) was noticed as to colour match and anatomical form. After 1-year follow-up, F2000 showed the most acceptable results as to the analysed criteria.

    Full Text Available BACKGROUND: Cervical cancer is a major public health problem in Latin America and the Caribbean (LA&C, showing some of the highest incidence and mortality rates worldwide. Information on HPV type distribution in high-grade cervical lesions (HSIL and invasive cervical cancer (ICC is crucial to predict the future impact of HPV16/18 vaccines and screening programmes, and to establish an appropriate post-vaccinal virologic surveillance. The aim was to assess the prevalence of HPV types in HSIL and ICC in studies in LA&C. METHODS AND FINDINGS: We performed a systematic review, following the MOOSE guidelines for systematic reviews of observational studies, and the PRISMA statement for reporting systematic reviews and meta-analyses. Inclusion criteria were at least ten cases of HSIL/ICC, and HPV-type elicitation. The search, without language restrictions, was performed in MEDLINE, Cochrane Library, EMBASE, LILACS from inception date to December 2009, proceedings, reference lists and consulting experts. A meta-analysis was performed using arc-sine transformations to stabilize the variance of simple proportions. Seventy-nine studies from 18 countries were identified, including 2446 cases of HSIL and 5540 of ICC. Overall, 46.5% of HSIL cases harbored HPV 16 and 8.9% HPV18; in ICC, 53.2% of cases harbored HPV 16 and 13.2% HPV 18. The next five most common types, in decreasing frequency, were HPV 31, 58, 33, 45, and 52. Study's limitations comprise the cross-sectional design of most included studies and their inherent risk of bias, the lack of representativeness, and variations in the HPV type-specific sensitivity of different PCR protocols. CONCLUSIONS: This study is the broadest summary of HPV type distribution in HSIL and ICC in LA&C to date. These data are essential for local decision makers regarding HPV screening and vaccination policies. Continued HPV surveillance would be useful, to assess the potential for changing type-specific HPV prevalence in

    Background The management of atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesions (ASCUS/LSIL) is still controversial and it is advisable to make a triage for these two cytological abnormalities. P16INK4 (P16)has been shown to be a potential biomarker for predicting high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer. The aim of the study was to determine the value of P16 expression by immunostaining method compared with high-risk human papillomavirus (HR-HPV) DNA test in the triage of ASCUS/LSIL women.Methods Totally 86 eligible residual liquid-based cytological specimens with ASCUS and 45 with LSIL were obtained.All specimens were submitted to HR-HPV DNA test (HC2) and P16 immunocytochemical staining simultaneously. And all women underwent colposcopy and biopsy after cytology.Results The positive rate of P16 staining was 32.6% in ASCUS and 42.2% in LSIL, which was significantly lower than that of HR-HPV test in both ASCUS (P<0.05) and LSIL (P<0.05). Moreover, the positive rate of P16 staining was 12.7% in normal histology, 61.5% in CIN 1, 87.0% in CIN 2-3, and 100.0% in cancer, in which P16 positive rate was significantly lower than HR-HPV positive rate in normal group. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of P16 staining for predicting ClN 2 or more were 87.5%, 68.6%, 38.9%, 96.0%, and 72.1%, respectively in the ASCUS; while 90.0%, 71.4%, 47.4%, 96.2% and 54.7%, respectively in the LSIL, in which the specificity and accuracy of P16 staining were significantly higher than those of HR-HPV test in both ASCUS and LSIL (P<0.05).Conclusion P16 immunostaining had significantly higher specificity and accuracy than HR-HPV DNA test for predicting for high-grade CIN and cervical cancer in ASCUS and LSlL and can be used for the tdage of women with ASCUS/LSlL cytological abnormality.

    Cervical cancer induced by human papillomavirus (HPV) is the fourth highest mortality causing cancer in women despite the use of prophylactic vaccines. E6 targeting represents an attractive strategy to treat this cancer. Indeed, oncoprotein E6 is produced by keratinocytes infected by HPV and is partially responsible for carcinogenesis. E6 interferes with the apoptosis process in stressed cells by degradation of p53 tumor suppressor gene. Our strategy consists in using E6 siRNA complexed with pegylated lipoplexes. The addition of hydrophilic polymer around the nanoparticles is crucial to use them by vaginal application on account of cervicovaginal mucus. Physicochemical characteristics were evaluated and in vitro assays were performed to evaluate transfection potential, E6 mRNA extinction and p53 re-expression. Cationic liposomes DOTAP/Cholesterol/DOPE 1/0.75/0.5 (N/P 2.5) with or without 50% DSPE-PEG2000 and associated with siE6 have demonstrated good physicochemical characteristics in terms of complexation, size, surface charge and stability. Both lipoplexes have been tested on CaSki cell line (HPV 16+) with 50 nM and 100 nM of siE6. Lipoplexes formulations induce 30-40% of E6 mRNA extinction and induce the re-expression of p53. In conclusion, pegylated anti-E6 lipoplexes have demonstrated their efficiency to cross the cellular membrane and to release siRNA into the cytoplasm confirmed by final p53 protein production.

    2012-06-01

    A 2-year randomized, controlled prospective study evaluated the clinical effectiveness of a one-step self-etch adhesive and a "gold-standard" three-step etch-and-rinse adhesive in non-carious Class-V lesions. The null hypothesis tested was that the one-step self-etch adhesive does perform clinically equally well as the three-step etch-and-rinse adhesive. A total of 161 lesions in 26 patients were restored with Clearfil AP-X (Kuraray). The restorations were bonded either with the "all-in-one" adhesive Clearfil S3 Bond (Kuraray) or with the three-step etch-and-rinse adhesive Optibond FL (Kerr). The restorations were evaluated at baseline and after 6 months, 1 and 2 years, regarding their retention, marginal adapation, marginal discoloration, caries occurrence, preservation of tooth vitality and post-operative sensivity. Retention loss, severe marginal defects and/or discoloration that needed intervention (repair or replacement) and the occurrence of caries were considered as clinical failures. The recall rate at 2 years was 93.8%. Only one Clearfil S3 Bond restoration was lost at the 2-year recall. All other restorations were clinically acceptable. The number of restorations with defect-free margins decreased severely during the 2-year study period (to 6.7% and 25.3% for Clearfil S3 Bond and Optibond FL, respectively). The Clearfil S3 Bond restorations presented significantly more small marginal defects at the enamel side than the Optibond FL restorations (Clearfil S3 Bond: 93.3%; Optibond FL: 73.3%; p = 0.000). Superficial marginal discoloration increased in both groups (to 53.3% and 36% for Clearfil S3 Bond and Optibond FL, respectively) and was also more pronounced in the Clearfil S3 Bond group (p = 0.007). After 2 years, the simplified one-step self-etch adhesive Clearfil S3 Bond and the three-step etch-and-rinse adhesive Optibond FL were clinically equally successful, even though both adhesives were characterized by progressive degradation in marginal

    Full Text Available Background: Anterior cervical discectomy and fusion (ACDF is a commonly performed surgical procedure. However, there is substantial debate regarding the role of physical therapy following this procedure. Therefore, we sought to determine current physical therapy practice following ACDF surgery, as well as determine physical therapists beliefs regarding rehabilitation following ACDF. Methods: One hundred and eighty three licensed Physical Therapists were invited to participate in a descriptive internet based survey; a total of 53 (29% completed the survey. Physical Therapists were assessed for their current practice, asked to rate the clinical usefulness of various treatment modalities, and indicate their recommendations regarding post-operative physical therapy for subjects following anterior discectomy and fusion. Results were then assessed for frequency distributions, with chi-square analysis for association between demographic data and practice recommendations. Results: The results indicate that Physical Therapists believe patients achieve superior outcomes with the inclusion of post-operative physical therapy, with a low risk of harm. Specific treatments indicated as most useful included endurance exercise (60.4%, isometric strengthening (56.6%, and stretching (45.3%. Other treatment options are discussed in detail. Conclusion: Physical Therapists identified specific activities that they felt were most appropriate for rehabilitation following ACDF surgery. These findings may help to direct both appropriate therapy prescription following ACDF, as well as future research.

    OBJECTIVE To investigate human papilloma virus (HPV) infections and the distribution of its subtypes in patients with cervical lesions and put forward counter measures for prevention and treatment of the disease. METHODS Cervical exfoliated cells collected from a total of 600 patients with cervical lesions were detected with Flow-through hybridization and gene chip technology, and followed by a complete evaluation of the HPV infection in related to different subtypes of cervical lesions. RESULTS The total HPV infection rate reached 78. 0%. The high-risk and low-risk HPV infection rates of patients with cervicitis/ condyloma acuminatum were 73. 1% and 18. 1%, respectively. The difference was statistically significant (P<0. 05). The high-risk and low-risk HPV infection rates of patients with cervical intraepithelial neoplasia (CIN) were 82. 6% and 7. 9%, respectively, the difference was statistically significant (P<0. 01). The high-risk and low-risk HPV infection rates of patients with cervical cancer were 96. 0% and 0, respectively, the difference was statistically significant (P<0. 01). The high-risk HPV infection rate increased with the degree of exacerbating of cervical lesions. The rate of single-type HPV infection was significantly higher than that of multi-type HPV infection in all kinds of cervical lesions (P<0. 01), while the rate of multi-type HPV infection increased with the increasing severity of cervical lesions. Different subtypes of HPV distributed differently in cervix lesions. CONCLUSION Detection of HPV subtypes is helpful for screening of the cervical lesions and diagnosis of the condition. For those patients infected especially with high-risk HPV, it is critical to conduct the early diagnosis, timely treatment and close follow-up to block the persistent HPV infection and prevent cervical cancer.%目的 探讨宫颈病变患者人乳头状瘤病毒(HPV)的感染状态及其亚型分布,提出预防治疗疾病的干预措施.方法 采用导流

    2015-06-15

    Electronic brachytherapy (eBT) has seen an insurgence of manufacturers entering the US market for use in radiation therapy. In addition to the established interstitial, intraluminary, and intracavitary applications of eBT, many centers are now using eBT to treat skin lesions. It is important for medical physicists working with electronic brachytherapy sources to understand the basic physics principles of the sources themselves as well as the variety of applications for which they are being used. The calibration of the sources is different from vendor to vendor and the traceability of calibrations has evolved as new sources came to market. In 2014, a new air-kerma based standard was introduced by the National Institute of Standards and Technology (NIST) to measure the output of an eBT source. Eventually commercial treatment planning systems should accommodate this new standard and provide NIST traceability to the end user. The calibration and commissioning of an eBT system is unique to its application and typically entails a list of procedural recommendations by the manufacturer. Commissioning measurements are performed using a variety of methods, some of which are modifications of existing AAPM Task Group protocols. A medical physicist should be familiar with the different AAPM Task Group recommendations for applicability to eBT and how to properly adapt them to their needs. In addition to the physical characteristics of an eBT source, the photon energy is substantially lower than from HDR Ir-192 sources. Consequently, tissue-specific dosimetry and radiobiological considerations are necessary when comparing these brachytherapy modalities and when making clinical decisions as a radiation therapy team. In this session, the physical characteristics and calibration methodologies of eBt sources will be presented as well as radiobiology considerations and other important clinical considerations.

    Background. Persistent infection with high-risk human papillomavirus (HR-HPV) has been demonstrated to be the necessary causal factor for developing cervical cancer. To know the most prevalent HR-HPV in different geographical areas is important to design diagnostic tests and implementation of vaccines. Objectives. The goal of this study is to evaluate the prevalence of HR-HPV in a total of 1001 patients, 198 with normal cytology results, 498 with low-grade squamous intraepithelial lesion (LSIL), and 205 with high-grade squamous intraepithelial lesion (HSIL) who attended our gynaecology department for opportunistic screening of HPV infection. Study design. Cervical samples were taken in a PreservCyt vial (Cytyc Corporation, Boxborough, MA). Hybrid capture assay was carried out following the manufacturer's instructions (Digene Corp., Gaithersburg, MD). All samples were further studied with polymerase chain reaction (PCR) (Linear Array HPV Genotyping Test, Roche Diagnostics, Mannheim, Germany). Results. Genotype 16 was the most prevalent HR-HPV in the three groups, 17.8% in the patients with normal cytology results, 22.3% in the LSIL group, and 60% in the HSIL group. Genotype 18 had a very low prevalence in all groups. Other HR-HPV genotypes such as genotype 31, genotype 58 and genotype 52 were found in significant numbers in HSIL patients. Discussion. Our data show that genotypes 16, 31, 58, and 52 are the most prevalent HR-HPV in cervical samples with severe intraepithelial lesion in Spain. There may be some geographical variation in prevalence of carcinogenic types, and it must be considered for designing diagnostic tests and vaccine.

    Full Text Available BACKGROUND: Human papillomavirus (HPV testing is included in the cervical cancer screening program in the triage of women with equivocal (ASC-US or low-grade (LSIL cytological lesions. These women have an increased risk for developing high grade dysplasia and cancer (CIN2+ compared to women with normal cytology. However, in order to avoid unnecessary follow-up, as well as overtreatment, a high positive predictive value (PPV of the triage test is important. METHODOLOGY/PRINCIPAL FINDINGS: The HPV test PreTect HPV-Proofer, detecting E6/E7 mRNA from the HPV types 16, 18, 31, 33 and 45, is used as triage test together with repeat cytology. PPV data for HPV E6/E7 mRNA testing during the period from January 2006 up to June 2009 are reported. In total, 406 of 2099 women (19.3% had a positive HPV test result. Of the women with a positive test result and with a histological diagnosis (n = 347, 243 women had histological high-grade dysplasia or cancer (CIN2+, giving a PPV of 70.0% (95% confidence interval [CI], 65.2%-74.8%. For HPV 16 or HPV 33 positive women above 40 years of age, the PPV was 83.7% (95% CI, 73.3%-94.0% and 84.6% (95% CI, 65.0%-100.0% respectively. The PPV of test positive women with HSIL cytology was 94.2% (95% CI, 88.7%-99.7%. CONCLUSIONS: When the result in triage is HPV mRNA positive, our data suggest direct treatment for women above 40 years of age or for women with a concurrent cytological HSIL diagnosis, contributing to better clinical safety for these women. In addition, by decreasing the time to treatment, thereby reducing the number of recalls, the patient management algorithm will be considerably improved, in turn reducing follow-up costs as well as unnecessary psychological stress among patients.

    Gillian E Cooke

    Full Text Available Increased survival rates among breast cancer patients have drawn significant attention to consequences of both the presence of cancer, and the subsequent treatment-related impact on the brain. The incidence of breast cancer and the effects of treatment often result in alterations in the microstructure of white matter and impaired cognitive functioning. However, physical activity is proving to be a successful modifiable lifestyle factor in many studies that could prove beneficial to breast cancer survivors. This study investigates the link between white matter lesion volume, moderate physical activity, and cognition in breast cancer survivors following treatment compared to non-cancer age-matched controls. Results revealed that brain structure significantly predicted cognitive function via mediation of physical activity in breast cancer survivors. Overall, the study provided preliminary evidence suggesting moderate physical activity may help reduce the treatment related risks associated with breast cancer, including changes to WM integrity and cognitive impairment.

    Clinical observations suggest the need for changing therapeutic management to a more active one in cases of cervical spine injury with damage to the spinal cord and nerve roots or brachial plexus. In 248 patients with these injuries treated initially conservatively the incidence of cervicobrachial pain was analysed. Neuralgic pains were present in 31.5% of cases, causalgic pains in 2.4% and sympathalgic pains in 2%. Conservative treatment conducted in these patients (89 cases) during many months after trauma had no effect on return of mobility. Long-term application of physioterapy prevented only temporarily the development of trophic changes and only partially relieved pains. Only surgical decompression of the spinal cord or spinal nerves with stabilization of damaged vertebrae caused disappearance of painful syndromes and improvement in the motor activity of the extremities. These observations show that early surgical intervention for decompression of the spinal cord, roots or brachial plexus should be advocated in these cases.

    Physical activity may help to prevent or delay brain atrophy. Numerous studies have shown associations between physical activity and age-related changes in the brain. However, most of these studies involved self-reported physical activity, not objectively measured physical activity. Therefore, the aim of this study was to examine the association between objectively measured physical activity, as determined using accelerometers, and brain magnetic resonance imaging (MRI) measures in older adults with mild cognitive impairment (MCI). We analyzed 323 older subjects with MCI (mean age 71.4 years) who were recruited from the participants of the Obu Study of Health Promotion for the Elderly. We recorded demographic data and measured physical activity using a tri-axial accelerometer. Physical activity was classified as light-intensity physical activity (LPA) or moderate-to-vigorous physical activity (MVPA). Brain atrophy and the severity of white matter lesions (WML) were determined by MRI. Low levels of LPA and MVPA were associated with severe WML. Subjects with severe WML were older, had lower mobility, and had greater brain atrophy than subjects with mild WML (all P<0.05). Multivariate analysis revealed that more MVPA was associated with less brain atrophy, even after adjustment for WML (β=-0.126, P=0.015), but LPA was not (β=-0.102, P=0.136). Our study revealed that objectively measured physical activity, especially MVPA, was associated with brain atrophy in MCI subjects, even after adjusting for WML. These findings support the hypothesis that physical activity plays a crucial role in maintaining brain health.

    With improved overall survival of cervical cancer patients,the importance of the quality of life (QOL)is increasingly recognized.This study was conducted to compare the QOL of women with different stage cervical cancer before and after treatment to facilitate improved cervical cancer prevention and treatment.We used the generic Medical Outcomes Study Short Form-36 (MOS SF-36) to collect QOL information.Based on SF-36,we interviewed cervical cancer patients at West China Second Affiliated Hospital and Sichuan Cancer Hospital between May 2010 and January 2011.A total of 92 patients with precancerous lesions,93 with early cancer,and 35 with advanced cancer responded to our survey.Average physical component summary (PCS) scores were significantly different between the three groups at every time point (P < 0.05).Average mental component summary (MCS) scores were significantly different between the three groups after treatment (P < 0.05).Average PCS and MCS scores increased gradually from the pretreatment to posttreatment period for patients with precancerous lesions.However,they reached the lowest at 1 month after treatment for patients with early and advanced cancers and rebounded between 1and 6 months after treatment.Our results indicate that patients with precancerous lesions and early cervical cancer show better overall QOL than do those with advanced cervical cancer.Additionally,patients with early cancer recover more quickly than do those with advanced cancer in terms of both physical and mental functions.Thus,early detection and treatment initiatives may improve the QOL for patients with precancerous lesions and cervical cancer.

    We report a 29-year-old woman who underwent routine gynecologic evaluation at a community clinic and had a cervical sample drawn for liquid-based cytologic evaluation. At cytology, many hyperchromatic crowded groups (HCG) were present, but a consensus could not be established whether the abnormal cells were primarily glandular or squamous with secondary endocervical glandular involvement. An interpretation of atypical endocervical cells, favor neoplastic, was rendered and biopsy advised if clinically appropriate. At biopsy, the cervix contained synchronous squamous cell carcinoma in situ, secondarily involving endocervical glands, and neighboring adenocarcinoma in situ. Immunohistochemistry for Ki-67 and p16(INK4A) crisply and precisely stained both the lesions, clearly separating them from the adjacent uninvolved mucosa. This case re-emphasizes the challenge associated with accurate evaluation of HCG at cytology, the significance of ancillary testing for surrogate markers of high-risk HPV (HR-HPV) infection, the need for adjunct testing for HPV-DNA in the setting of HCG at cervical cytology, and a recommendation to set up studies to evaluate the role of surrogate markers of HR-HPV infection in cytologic samples with HCG.

METHODS: A cross-sectional study was conducted including 70 women (35 with cytological cervical lesions and 35 with normal smears. Colposcopy and biopsy when necessary were performed and Chlamydia infection was determined by direct immunofluorescence. Analysis variables were age, race, precedence, schooling, marital status, menarche, age at first sexual intercourse, parity, number of sexual partners, vaginal discharge, previous Pap smear, STD episodes, cervical cauterization, contraceptive methods, familial antecedents of cervical cancer, alcohol intake, use of illicit and immunosuppressive drugs, Papanicolaou result and cervical Chlamydia l infection. To determine the strength of association prevalence ratio (PR and its 95% confidence interval were calculated. Multivariate analysis was performed for controlling potentially confounding variables. RESULTS: the frequency of Chlamydia l infection was significantly greater in patients with intraepithelial cervical lesions (80.0% vs. 14.3%; PR = 5.60; 95% CI = 2,44 - 12,82. When the factors associated with Chlamydia l infection were analyzed, the only variable that remained significantly associated after multivariate analysis was previous episode of STD (OR=63,47; 95% CI = 13,93 - 289,09. CONCLUSION: Chlamydia trachomatis infection is associated with intraepithelial cervical lesions and history of STD should be considered for treatment and follow-up of these patients.

    The present study examined the effects of physical and mental workload during computer tasks on muscle activity and physiological measures. Activity in cervical postural muscles and distal forearm muscles, heart rate and blood pressure were compared among three tasks and rest periods of 15 min each in an experimental study design. Fourteen healthy pain-free adults participated (7 males, mean age = 23.2 ± 3.0 years) and the tasks were: (1) copy-typing ("typing"), (2) typing at progressively faster speed ("pacing"), (3) mental arithmetic plus fast typing ("subtraction"). Typing task was performed first, followed by the other two tasks in a random order. Median muscle activity (50th percentile) was examined in 5-min intervals during each task and each rest period, and statistically significant differences in the "time" factor (within task) and time × task factors was found in bilateral cervical erector spinae and upper trapezius muscles. In contrast, distal forearm muscle activity did not show any significant differences among three tasks. All muscles showed reduced activity to about the baseline level within first 5 min of the rest periods. Heart rate and blood pressure showed significant differences during tasks compared to baseline, and diastolic pressure was significantly higher in the subtraction than pacing task. The results suggest that cervical postural muscles had higher reactivity than forearm muscles to high mental workload tasks, and cervical muscles were also more reactive to tasks with high physical demand compared to high mental workload. Heart rate and blood pressure seemed to respond similarly to high physical and mental workloads.

    We evaluated Linear Array (LA), a newly commercialized PGMY09/11 L1 consensus primer PCR test that detects 37 human papillomavirus (HPV) genotypes by reverse line blot hybridization, for the detection of individual HPV genotypes and carcinogenic HPV and its clinical performance for detecting 2-year cumulative cervical precancer and cancer using archived specimens from the Atypical Squamous Cell of Undetermined Significance (ASCUS) and Low-Grade Squamous Intraepithelial Lesion Triage Study. LA testing was conducted on enrollment specimens from women referred because of an ASCUS Pap test. To gauge the performance of the new test, the results were compared to those of its prototype predecessor assay, Line Blot Assay (LBA), restricted to paired results (n = 3,335). LA testing was done masked to LBA results and clinical outcomes. The results of LA and LBA testing were compared for detection of carcinogenic HPV and clinical outcomes of cervical precancer and cancer. Overall, 50% and 55% of the women tested positive for carcinogenic HPV by LBA and LA, respectively (P < 0.0001). The percent agreement for carcinogenic HPV detection was 88%, percent positive agreement was 80%, and kappa was 0.76 for detection of carcinogenic HPV by the two assays. There was a significant increase in detection by LA for most of the 37 HPV genotypes targeted by both assays, including for 13 of 14 carcinogenic HPV genotypes. LA detected more multiple-genotype infections for all HPV genotypes among HPV-positive women (P < 0.0001) and for carcinogenic HPV genotypes among carcinogenic-HPV-positive women (P < 0.0001). LA was more sensitive (92.3% versus 87.1%; P = 0.003) and less specific (48.2% versus 54.0%; P < 0.0001) than LBA for 2-year cumulative cervical precancer and cancer as diagnosed by the Pathology Quality Control Group. In conclusion, we found LA to be a promising assay for the detection of HPV genotypes and carcinogenic HPV, and it may be clinically useful for the detection of

    OBJECTIVE: To evaluate the value of the DNA quantitative cytology with liquid-based cytology in cervical cancer prevention and treatment. METHODS: 4 352 cases of patients in our hospital outpatient gynecologic from 01-01-2009 to 10-31-2010 were involved in this study. All the 504 cases which were recommended biopsy were conducted colposcopy and biopsy. The pathological changes were observed after the routine HE staining. Then the positive coincidence rate of the liquid-based cytology was calculated with routine HE staining and DNA Feulgen staining with routine HE staining respectively. RESULTS: The positive rate was 52. 18% (263/504) with the diagnosis of the TBS biopsy criteria. The positive rate was 66.67%(336/504) with the diagnosis of the DNA Feulgen staining biopsy criteria, While the positive rate was 81.75 % (412/504) with the diagnosis of the two combined cytological method biopsy criteria. There was significant difference among the three methods (P<0. 05). CONCLUSIONS: DNA Feulgen staining compared with the single liquid-based cytology, the rate of early detection of cervical lesions is improved significantly. The false negative rate of thc liquid-based cytology can be reduced by the combination of the two, but also the detection rate of cervical lesions of early can be improved.

    Full Text Available Introduction: by means of the decisions on whether to introduce the HPV vaccination, Public Health has already established the importance of associating the vaccination strategy to the policy of secondary prevention. The screening + vaccination strategy is more effective than the two methods taken individually. In support of this combined strategy and in order to make available per each region concrete elements for their regional planning, an assessment has been made, which also takes into account the effect of cross-protection regarding high-risk strains not contained in both vaccines, bivalent and quadrivalent, and more frequently responsible for pre-cancerous lesions and cervical cancer (CCU. This analysis evaluates the costs and benefits of screening + vaccination strategy in a 12-year-old female cohort. Furthermore, the paper provides results that may be useful to assess the opportunity to extend the vaccination to a second cohort of 24-25-year-old women. The analysis is preceded by a brief summary of CCU epidemiology available data, public health policies that give precise guidelines for vaccination strategies and analytical tools suitable to support public policy makers to efficiently allocate resources. Methods: two different models were used for two regional analyses.The vaccines may have different sustained- and cross-protection levels against non-vaccine oncogenic HPV-types. In the first analysis, a prevalence-based model estimated the potential net difference in HPV-related lesions (abnormal pap smear, cervical intraepithelial neoplasia (CIN, cervical cancer (CC and genital warts (GW and associated costs generated by the two vaccines. Vaccine efficacy rates were based on published data for each vaccine. Lifetime vaccine efficacy was assumed. Results are reported over one year after reaching a steady state. Incidence and treatment costs were obtained from Italian and European sources. We also performed a cost-effectiveness analysis

    Full Text Available BACKGROUND: The control arm of PATRICIA (PApilloma TRIal against Cancer In young Adults, NCT00122681 was used to investigate the risk of progression from cervical HPV infection to cervical intraepithelial neoplasia (CIN or clearance of infection, and associated determinants. METHODS AND FINDINGS: Women aged 15-25 years were enrolled. A 6-month persistent HPV infection (6MPI was defined as detection of the same HPV type at two consecutive evaluations over 6 months and clearance as ≥2 type-specific HPV negative samples taken at two consecutive intervals of approximately 6 months following a positive sample. The primary endpoint was CIN grade 2 or greater (CIN2+ associated with the same HPV type as a 6MPI. Secondary endpoints were CIN1+/CIN3+ associated with the same HPV type as a 6MPI; CIN1+/CIN2+/CIN3+ associated with an infection of any duration; and clearance of infection. The analyses included 4825 women with 16,785 infections (3363 women with 6902 6MPIs. Risk of developing a CIN1+/CIN2+/CIN3+ associated with same HPV type as a 6MPI varied with HPV type and was significantly higher for oncogenic versus non-oncogenic types. Hazard ratios for development of CIN2+ were 10.44 (95% CI: 6.96-15.65, 9.65 (5.97-15.60, 5.68 (3.50-9.21, 5.38 (2.87-10.06 and 3.87 (2.38-6.30 for HPV-16, HPV-33, HPV-31, HPV-45 and HPV-18, respectively. HPV-16 or HPV-33 6MPIs had ~25-fold higher risk for progression to CIN3+. Previous or concomitant HPV infection or CIN1+ associated with a different HPV type increased risk. Of the different oncogenic HPV types, HPV-16 and HPV-31 infections were least likely to clear. CONCLUSIONS: Cervical infections with oncogenic HPV types increased the risk of CIN2+ and CIN3+. Previous or concomitant infection or CIN1+ also increased the risk. HPV-16 and HPV-33 have by far the highest risk of progression to CIN3+, and HPV-16 and HPV-31 have the lowest chance of clearance.

    Ectopic cervical deciduosis is generally an accidental finding during pregnancy, and usually presents without any symptoms or need for therapeutic intervention. However, it can sometimes imitate dysplasia or carcinoma. We report a case of a 34-year-old G2P0, with a history of cervical dysplasia, presenting at 11 weeks of gestation, with vaginal blood loss. During examination, lesions mimicking dysplasia were found on the cervix. Histological examination reported cervical deciduosis. Deciduosis is a benign change during pregnancy and will resolve spontaneously. With the increasing use of cytology and colposcopy, the reported incidence is growing. When it is hard to differentiate between dysplasia and deciduosis, histological confirmation should be considered.

    Full Text Available Integration of human papillomavirus (HPV DNA into the host genome is a critical aetiological event in the progression from normal cervix to intraepithelial neoplasm, and finally to invasive cervical cancer. However, there has been little work on how HPV integration status relates to treatment outcome for cervical carcinomas. In the current study, HPV E2 and E6 gene copy numbers were measured in 111 cervical cancer tissues using real-time QPCR. Integration patterns were divided into four groups: single copy-integrated with episomal components (group 1, single copy-integrated without episomal components (group 2, multicopy tandem repetition-integrated (group 3, and low HPV (group 4 groups. A relapse-predicting model was constructed using multivariable Cox proportional hazards model to classify patients into different risk groups for disease-free survival (DFS. The model was internally validated using bootstrap resampling. Oligonucleotide microarray analysis was performed to evaluate gene expression patterns in relation to the different integration groups. DFS rate was inferior in the order of the patients in group 4, group 2/3, and group 1. Multivariate analysis showed that histologic grade, clinical stage group, and integration pattern were significant prognostic factors for poor DFS. The current prognostic model accurately predicted the risk of relapse, with an area under the receiver operating characteristic curve (AUC of 0.74 (bootstrap corrected, 0.71. In conclusion, these data suggest that HPV integration pattern is a potent prognostic factor for tailored treatment of cervical cancer.

    1997-12-01

    A 16-year-old athlete developed neck pain after being dropped on his head with his neck flexed while recreationally wrestling. Initial cervical spine radiographs were negative, but he continued to have neck and arm pain, especially after heading a wet soccer ball. Two months after the initial injury, he had a positive Spurling test; cervical spine CT then revealed a parasagittal linear fracture through the body of C-7. The patient avoided contact and collision activities and had no further physical problems. For patients who suffer cervical spine trauma, adequate visualization of the cervical spine can help prevent catastrophic outcomes.

    The purposes of this study were to estimate the infection frequency of Human Papilomavirus (HPV) and to identify the viral types in patients with diagnosis of uterine cervical cancer (UCC) and High Grade Squamous Intraepitelial lesions (HGSILs), and to correlate the molecular findings versus HPV infection suggestive clinical findings. Biopsies from 50 patients (37 HGSILs and 13 UCC) histopathologically diagnosed were studied. The presence of HPV were detected by means of the polymerase chain reaction (PCR) using consensus primers for types 6, 11, 16, 18, 31, 33, 35, and 58 among others, as well as specific primers for some of them. The frequencies for HPV 16, 18, 33, 35, and 58 in HGSIL samples were 24.3, 2.7, 0, 5.4 and 16.2% respectively. In UCC samples were 61.5, 7.7, 0, 0 and 15.4% with significative differences only for HPV 16. Clinical findings (histologic, colposcopic and histopathologic), showed deficient diagnostic accuracy in the identification of HPV 16 in HGSIL, wich resulted less frequent and there is a high frequency of HPV. These results are similar to those previously described in our country and the other populations, with the exception of HPV16 in HGSIL, wich resulted less frequent and there is a high frequency of HPV 58 in our region. When analyzing clinical features with the presence of HPV DNA, we conclude that these are insufficient to discard or establish the possibility of HPV infection in patients with HGSIL's and UUC.

    Purpose: Despite the widespread screening programs, cervical cancer remains the third most common cancer in developing countries. Based on the implementation of cervical screening programs with the referred adoption of improved screening methods in cervical cytology with the knowledge of the important role of the human papilloma virus (HPV) it's incidence is decreased in the developed world. Even if cervical HPV infection is incredibly common, cervical cancer is relatively rare. Depending on the rarity of invasive disease and the improvement of detection of pre-cancerous lesions due to the participation in screening programs, the goal of screening is to detect the cervical lesions early in order to be treated before cancer is developed. In populations with many preventive screening programs, a decrease in cervical cancer mortality of 50-75% is mentioned over the past 50 years. The preventive examination of vagina and cervix smear, Pap test, and the HPV DNA test are remarkable diagnostic tools according to the American Cancer Association guidelines, in the investigation of asymptomatic women and in the follow up of women after the treatment of pre-invasive cervical cancer. The treatment of cervical cancer is based on the FIGO 2009 cervical cancer staging.

    Cervical angina has been widely reported as a cause of chest pain but remains underrecognized. This series demonstrates the varied clinical presentation of patients with cervical angina, the delay in diagnosis, and the extensive cardiac examinations patients with this condition typically undergo prior to a definitive diagnosis. Recognition of this condition in patients with acute chest pain requires a high index of suspicion and an awareness of the common presenting features and clinical findings of cervical angina.

    2016-11-01

    Full Text Available Background: Tinnitus is a very common symptom that often causes distress and decreases the patient’s quality of life. Apart from the well-known causes, tinnitus can in some cases be elicited by dysfunctions of the cervical spine or the temporomandibular joint(TMJ. To date however, it is unclear whether alleviation of these dysfunctions, by physical therapy treatment, also decreases the tinnitus complaints. Such physical therapy could be an interesting treatment option for patients that are now often left without treatment.Objectives: The aim of this review was to investigate the current evidence regarding physical therapy treatment in patients with tinnitus.Data sources: The online databases Pubmed, Web of Science, Cochrane and Embase were searched up to March 2016. Two independent reviewers conducted the data extraction and methodological quality assessment.Study eligibility criteria: Only randomized controlled trials and quasi-experimental trials were included in the review. Studies had to be written in English, French, Dutch or German.Participants and interventions: The included studies investigated the effect of physical therapy treatment modalities on tinnitus severity in patients suffering from subjective tinnitus.Results: Six studies were included in this review, four investigating cervical spine treatment and two investigating TMJ treatment. These studies show positive effects of cervical spine treatment (manipulations, exercises, triggerpoint treatment on tinnitus severity. Additionally, decrease in tinnitus severity and intensity was demonstrated after TMJ treatment, following splints, occlusal adjustments as well as jaw exercises.Limitations: The risk of bias in the included studies was high, mainly due to lack of randomization, lack of blinding of subjects, therapists and/or investigators. Additionally, risk of bias is present due to incomplete presentation of the data and selective reporting. A major issue of the reviewed papers

  7. 'Do not touch' lesions of the skull base.

    2014-08-01

    Imaging of the skull base presents many challenges due to its anatomical complexity, numerous normal variants and lack of familiarity to many radiologists. As the skull base is a region which is not amenable to physical examination and as lesions of the skull base are generally difficult to biopsy and even more difficult to operate on, the radiologist plays a major role in directing patient management via accurate image interpretation. Knowledge of the skull base should not be limited to neuroradiologists and head and neck radiologists, however, as the central skull base is routinely included in the field of view when imaging the brain, cervical spine, or head and neck with computed tomography or magnetic resonance imaging, and hence, its nuances should be familiar to general radiologists as well. We herein review the imaging findings of a subcategory of lesions of the central skull base, the 'do not touch' lesions.

    Objective: To explore the clinical value of hybrid capture 2 (hc2) in detection of high risk HPV in cervical cancer and pre-cancerous cervical lesions. Methods: Cervix exfoliated cells were detected with the second generation of hybrid capture hc2 method, and the diagnostic results such as specificity, sensitivity, accuracy, and pedicted value were compared with that of pathological diagnosis respectively. Results: The infection rate of HPV assayed by hc2 was 43. 8% in atypical squamous cell of undetermined signification (ASCUS), 7. 8% in ASCUS-H, 9. 7% low-grade squamous intraepithelial lesion(LSIL), and 28. 7% in high-grade squamous intraepithelial lesion (HSIL) respectively according to TBS diagnosis and classification system. For high grade-squ-mous intraepithelial lesion≥(CIN II ), the specificity, sensitivity, positive-predictive value and negative-predictive value by hc2 were 66. 7% , 93. 4% , 60. 0% , and 95. 0% respectively. In high virus load assay, there was significant difference between cervical cancer and CIN I (P<0. 01), and between cervical cancer/CIN and NILM group (P<0. 01), but there was no difference be-tween CIN and cervical cancer. Conclusion; The high-risk HPV test with hc2 is still a good method in diagnosing cervical cancer and premalignant lesion. Examining the high-risk HPV viral load with hc2 is related to cervical cancer and premalignant lesions, but not related to the severity of cervical lesions.%目的:探讨高危人类乳头瘤病毒(HPV)第二代杂交捕获实验(hc2)检测应用于宫颈癌以及癌前病变检查中的临床价值.方法:用hc2检测其子宫颈脱落细胞,以病理诊断作为金标准对检测结果进行分析和评价,对其特异度、敏感度、准确性、预测值等检测并分析.结果:hc2法检测高危型HPV的感染状况为无明确意义的非典型细胞的改变(ASCUS)44.7%,不典型鳞状细胞不除外高度病变(ASCUS-H)7.8%,低度鳞状上皮内病变(LSIL)19.7%,高

  10. Fractures of the cervical spine

    Full Text Available OBJECTIVES: The aim of this study was to review the literature on cervical spine fractures. METHODS: The literature on the diagnosis, classification, and treatment of lower and upper cervical fractures and dislocations was reviewed. RESULTS: Fractures of the cervical spine may be present in polytraumatized patients and should be suspected in patients complaining of neck pain. These fractures are more common in men approximately 30 years of age and are most often caused by automobile accidents. The cervical spine is divided into the upper cervical spine (occiput-C2 and the lower cervical spine (C3-C7, according to anatomical differences. Fractures in the upper cervical spine include fractures of the occipital condyle and the atlas, atlanto-axial dislocations, fractures of the odontoid process, and hangman's fractures in the C2 segment. These fractures are characterized based on specific classifications. In the lower cervical spine, fractures follow the same pattern as in other segments of the spine; currently, the most widely used classification is the SLIC (Subaxial Injury Classification, which predicts the prognosis of an injury based on morphology, the integrity of the disc-ligamentous complex, and the patient's neurological status. It is important to correctly classify the fracture to ensure appropriate treatment. Nerve or spinal cord injuries, pseudarthrosis or malunion, and postoperative infection are the main complications of cervical spine fractures. CONCLUSIONS: Fractures of the cervical spine are potentially serious and devastating if not properly treated. Achieving the correct diagnosis and classification of a lesion is the first step toward identifying the most appropriate treatment, which can be either surgical or conservative.

    170 patients with suspected lesions of the cervical part of the medulla were examined using nuclear magnetic resonance (NMR) tomography. 27 cases revealed no pathological changes in the regions of the cervical medulla, the cervical canal and of the cervical spine. 143 cases produced pathological findings whose diagnoses determined therapeutical approach. Verified pathological changes comprised anomalies of the cranio-cervical junction like basilar impression and Arnold-Chiari malformation, various types of cavity formation in the cervical medulla (syringomyelia, hydromyelia), demyelinization processes, intramedullary and extramedullary tumours, intervertebral disk degeneration processes, dislocation of intervertebral disks and spondylophytes with spinal stenoses. Sagittal sections in different functional positions allowed to demonstrate the biomechanical effects of extramedullary masses on the cervical medulla. However, proven tumours could not be differentiated successfully using histological methods. Nevertheless, NMR tomography will replace invasive methods like conventional cervical myelography and CT myelography in diagnostic clarification of diseases of the cervical medulla.

    2014-01-01

    Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark......, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented...... cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT...

    Objective To evaluate the function and application of high risk human papillomavirus (HR-HPV) test, liquid-based cytology test (LCT) and histological biopsy with colposcopy. Methods 601 patients with abnormal LCT results in the outpatient department of gynecology from January 2009 to October 2011 were reexamined using HR-HPV test. The results of HR-HPV and LCT tests were compared with histological biopsy under colposcope. Results 67.2% (404/601) of the patients were found to be HR-HPV positive. The infection rate of patients with ASC-US, LSIL, ASC-H, HSIL and CA was 45.5%, 66.2%, 74.4%, 89.1% and 100.0%, respectively, and the difference was significant (P<0.05). The sensitivity of diagnosing CIN and cervical lesions in the combined LCT and HR-HPV test was 86.1%. The result was higher than the LCT test (77.1%) and HR-HPV test (72.0%) (P<0.05). The false negative rate (13.9%) was lower than the LCT and HR-HPV test (P<0.05). The compliance rate was 50.8% (102/201) between cervical inflammation, 22 cases (11.0%) had CIN I , 40 cases (19.9%) had CIN II , 34 cases (16.9%) had CIN I , and 2 cases (1.0%) had cervical cancer. In the HR-HPV test, the detection rate was 59.2% (119/201); with a sensitivity of 71.7% (71/99), specficity of 53.0% (54/102) and an accuracy of 64.7%. Conclusion The pathogenic development of cervical lesion is correlated closely with HR-HPV infection.

    Objective To explore the effect of folic acid and DNA methyltransferase 1 (DNMT1) on cervical cancer and cervix precancerous lesion. Methods 100 patients with cervix squamouscell carcinoma (SCC), 101 patients with cervical intraepithelial neoplasm (CIN) and 109 patients with cervix inflammation (CI) diagnosed by histology were included in this study. Radioimmunoassay (RIA), polymerase chain reaction (PCR) and Western blot were used to detect the levels of serum folate, HPV16 infection and the expression of DNMT1 protein,respectively. Results The average levels of serum folate were (2.60 ± 1.61) ng/ml, (3.14 + 2.08) ng/ml and (3.32+1.74) ng/ml,and the expression of DNMT1 protein were 2.40 + 0.99,1.88 + 0.33 and 0.89 ± 0.29 in the group of SCC, CIN and CI, respectively.The relationship of folate levels and DNMT1 protein expression showed inverse correlation (r=-0.186, P=0.00l). The results in our study indicated that there was an additive interaction between low-level of serum folate and high-expressionof DNMT1 protein related to the risk of CIN and SCC, with OR value as 2.50(95%C/: 1.21-9.22) and 6.03 (95%C/: 2.79-21.72) respectively. The relative excessrisk of interaction (RERI) , attributableproportion of interaction (API) and synergy index (S) were 0.92, 0.36 and 2.59 in the CIN group while 2.47, 0.41 and 1.96 in the SCC group. Conclusion The low level of serum folate and high expression of DNMT1 protein seemed to be associated with high risk of cervical cancer and its precancerous lesion. It suggested that there might be a synergistic action between serum folate and DNMT1 in the progression of cervix carcinogenesis.%目的 探讨叶酸和DNA甲基转移酶1(DNMT1)与宫颈癌发生发展的关系及其在宫颈癌变中的相互作用.方法 选择经病理学确诊的宫颈鳞状细胞癌(SCC)患者100例、宫颈上皮内瘤样变(CrN)患者101例和宫颈炎(CI)患者109例为研究对象.在收集全部对象人口学特征、生殖因素等相关资料

    Diabetes may affect the typical physical findings associated with cervical spondylotic myelopathy, as coexisting diabetic neuropathy may dampen expected hyperreflexia and also produce non-dermatomal extremity numbness. Most large studies of surgically treated diabetic patients with cervical spondylotic myelopathy have focused upon infection rates rather than exploring any differences in the presenting physical signs. We conducted a retrospective study of the pattern of presenting neurological signs and symptoms and of the clinical outcomes in 438 patients surgically treated for cervical spondylotic myelopathy, 79 of whom had diabetes. Compared with non-diabetic patients, those with diabetes were slightly older and had lower preoperative modified Japanese Orthopaedic Association (mJOA) scores. Those with diabetes also had a significantly higher incidence of hyporeflexia and a higher incidence of a positive Babinski sign, but there was no difference in the appearance of the Hoffman sign. The magnitude of mJOA improvement after surgery was comparable. We conclude that diabetes may alter the typical signs and symptoms of cervical spondylotic myelopathy and suggest that knowledge of the differences may aid in securing a prompt and accurate diagnosis.

    Full Text Available The detection of zeal tends to be one of them factors multiple that affect the rate of pregnancy in dairy farms; because females are inseminated outside the most appropriate time to reach fertilization. The objective of the present study was to analyze macroscopic characteristics(quantity, appearance and consistency, crystallization phenomenon, pH, level of calcium, magnesium, potassium, sodium and chlorine in the cervical mucus of heifers in order to relatethese properties with the periovulatory period. Be used 20 Holstein heifers. Mucus was obtained prior to insemination and it was picked up by suction from the cervix. pH was determined using reactive tape (6-7,9 and the degree of crystallization (0-4 was evaluated according to typical and atypical fern leaf formations. It was determined pH test (6-7,9 tape and evaluate the degree of crystallization (0 - 4 according to the typical and atypical formations of fern leaves. Ionic content was determined using commercial kits (Wiener SAIC laboratories. Pregnancy was detected in 60 days post insemination. Each variable was described by its mean and deviation standard and by ANOVA established significant differences between means. It showed that the pregnancy was related to a mucus contains a concentration significantly less than K and Mg, compared with empty heifers (K, P:7,76 V: 12,97; Mg, P:2, 80 V:3,93; p<0,05 t=2,16. pH was significantly higher in the pregnant females, and the crystallization grade significantly lower (pH P:7, 60 V: 6, 23; crystallization P: 1,31 V2, 21; p<0,01 t=3,01. The results allow concluding that the optimum to inseminate was associated with cervical mucus observed macroscopically liquid, transparent and generous; with a pH above 7.0 and that it was forming atypical leaves of fern with an average of 1.31. Probably, the liquid consistency or liquid facilitates the transport of sperm and an osmotic active, responsible for the retention force is not related to content perhaps

    Cervical spine radiographs of 38 patients orginating from 145 consecutive cases with Reiter's syndrome (RS) were reviewed. Five of these 145 patients (3.4%) had cervical spine manifestations: anterior atlanto-axial dislocation 2, craniovertebral lesions typical for rhreumatoid arthritis (RA), spondylitis typical for ankylosing spondylitis (AS) and anterior ossification, one each. Four of these patients were males. Cervical lesions in RS turned out to be rare. These lesions are alone indistinguisable from those of other chronic rheumatic inflammatory diseases.

    1989-01-01

    Myocardial infarction area and left-ventricular myocardial contractility, determined by sectoral scanning, and exercise tolerance were assessed in 47 myocardial infarction patients with isolated coronary arterial lesions. The area under myocardial infarction was shown to be dependent on the site of the atherosclerotic process rather than the degree of stenosis in patients with isolated coronary arterial lesions. A relationship was established between the incidence of complications developing in the acute phase of infarction and the degree of stenosis. The disease was complicated more frequently in patients with coronary arterial occlusion as compared to those with severe coronary-arterial stenosis. High stress tolerance, irrespective of the site of myocardial infarction, is an evidence of great functional potentials in this category of patients.

    Caspar, W; Barbier, D D; Klara, P M

    1989-10-01

    A technique for anterior cervical iliac graft fusion with standardized, commercially available screw and plate fixation (Caspar plating) has been developed. The step-by-step procedure, as well as the instruments designed to facilitate the procedure, are described in this report. Sixty cases of cervical trauma (fractures, subluxations, ligamentous instability, or a combination of these problems) were treated with Caspar plating. All patients obtained fusion, and stability was achieved immediately after surgery without external stabilization. No unusual surgical complications occurred, and the most dreaded complication of dural penetration by drilling or screw placement was not observed. This report details the neurological presentation, anatomical lesions, surgical therapy, and outcome of these patients. Caspar plating combines the advantage of an anterior surgical approach with immediate postoperative stabilization without external stabilization. This advantage persists even in the presence of posterior ligamentous instability. The technique is an important addition to the surgical treatment of cervical trauma.

    A previous clinical trial showed that long-term use of saliva-stimulating polyol (xylitol and sorbitol) chewing gums was associated with arrest of dental caries in young subjects. After a 20-22-month intervention (when the subjects were 8 years old), a total of 23 primary teeth with extensive dentin caries lesions whose surface in clinical examination was found to be totally rehardened (remineralized) could be removed because the teeth were near their physiologic exfoliation time. These teeth were subjected to histologic, microhardness, and electron microscopic tests. The majority of the specimens had been remineralized from the surface by a non-cellular-mediated process within the remaining collapsed, organic extracellular matrix associated with the remaining dentinal surface. Many of the underlying dentinal tubules were filled with a matrix that had been subsequently mineralized. Dental microanalyses showed that the topmost (outer) 20-microm-thick rehardened layer of the lesions exhibited the highest Ca:P ratio, which leveled off at a depth of approximately 150 microm. The rehardened surface layer (normally <0.1 mm in thickness) was significantly (P < 0.001) harder than sound dentin and nearly as hard as sound enamel. Although the main source of the mineral present in the rehardened layer was most likely of salivary origin, some extracellular remineralization was probably mediated by odontoblasts. The results complete the dinical diagnoses of the original trial and suggest that regular use of polyol chewing gums may induce changes in dentin caries lesions, which in histologic and physiochemical studies show typical characteristics of rehardening and mineralization.

    Physical phantoms are needed for the evaluation and optimization of new digital breast tomosynthesis (DBT) systems. Previously, we developed an anthropomorphic phantom based on human subject breast CT data and fabricated using commercial 3D printing. We now present three key advancements: voxelized 3D printing, photopolymer material doping, and 2D inkjet printing of lesion inserts. First, we bypassed the printer's control software in order to print in voxelized form instead of conventional STL surfaces, thus improving resolution and allowing dithering to mix the two photopolymer materials into arbitrary proportions. We demonstrated ability to print details as small as 150μm, and dithering to combine VeroWhitePlus and TangoPlus in 10% increments. Second, to address the limited attenuation difference among commercial photopolymers, we evaluated a beta sample from Stratasys with increased TiO2 doping concentration up to 2.5%, which corresponded to 98% breast density. By spanning 36% to 98% breast density, this doubles our previous contrast. Third, using inkjet printers modified to print with iopamidol, we created 2D lesion patterns on paper that can be sandwiched into the phantom. Inkjet printing has advantages of being inexpensive and easy, and more contrast can be delivered through overprinting. Printing resolution was maintained at 210 μm horizontally and 330 μm vertically even after 10 overprints. Contrast increased linearly with overprinting at 0.7% per overprint. Together, these three new features provide the basis for creating a new anthropomorphic physical breast phantom with improved resolution and contrast, as well as the ability to insert 2D lesions for task-based assessment of performance.

    Objective:To evaluate the clinical effect of different gingival retraction methods in the treatment of subgingival non-carious cervical lesions. Methods; The teeth with wedge-shaped defects at subgingival depth of 0 - 2 mm were selected and divided into 3 groups. 40 teeth with the defects at subgingival depth of 0-1 mm in group 1 were restored with the aid of gingival retraction code. 40 teeth with the defects at subgingival depth of 0 - 1 mm in group 2 were restored with the aid of LM gingival retractor. 20 teeth with the defects at subgingival depth of 1 - 2 mm in group 3 were restored with the aid of LM gingival retractor. Additionally, 40 teeth with the defects above gingival margins were directly restored as the controls. All the defects were filled with Clearfil SE Bond system and 3M Z250 composite resin. All cases were followed up for 1 year、The results were evaluated by modified USPHS criteria and statistically analyzed using the Fishers exact test. Results; 100% retention rates were recorded in the 3 experimental groups, 2 restorations of the control groups were lost. No significant differences were detected for one year successful rates among the four groups ( P >0. 05). There was no significant difference in main indexes including retention, marginal adaptation, recurrent caries, marginal discolor, new defect, gingival response and pulp response(P >0. 05). In each group, the parameters of assessment between baseline and 1-year follow-up were not significantly different(P >0. 05). Conclusion; With the aid of effective gingival retraction methods, subgingival defects can be satisfactorily restored. The depth of cervical margin does not affect the clinical effects. The LM gingival retractor is valuable for the treatment of the subgingival wedge-shaped defects.%目的:评估不同排龈方法修复龈下楔状缺损(楔缺)的临床疗效.方法:选择颈部边缘位于龈下0~2 mm内较难充填的楔缺,分3组:Ⅰ组:龈边缘位于龈下0~1 mm

    A 35 year old woman with endometrial cancer and cervical extension underwent F18 FDG PET CT and MRI studies after resection of a cervical mass presumed to be cervical myoma. The patient underwent cervical myomectomy and the histopathologic report revealed poorly differentiated invasive carcinoma. Cervical cancer was ruled out because the patient had no history of sexual intercourse and was negative for human papilloma virus infection. The patient underwent radical hysterectomy, bilateral salpingo oophorectomy, pelvic and para aortic lymph node dissection, and multiple biopsies. F18 FDG PET CT showed intense FDG uptake along the cervix wall. T2 weighted MRI also revealed a mass lesion with high SI involving the anterior and posterior lips of the uterine cervix. Another area of focal increased uptake above the endometrial lesion in the left pelvic cavity was observed on PET CT and MRI, possibly due to a functioning ovary. PET CT and MRI were interpreted as showing a dual concordant malignant lesion due to separated FDG uptakes and high SI without any connection between the cervical and endometrial lesions. F18 FDG PET CT showed intense FDG uptake along the endometrium. Given the patient's history and the fact that she was not menstruating at the time of imaging, this intense uptake was interpreted as another pathologic lesion, suggesting dual primary lesions. A suspected heterogeneous mass lesion along the endometrium suggesting concordant endometrial cancer was found on MRI. Endometrial cancer with cervical extension is sometimes difficult to differentiate from primary cervical cancer. The final histopathologic report showed poorly differentiated endometrial adenocarcinoma with cervical extension, although the FDG PET CT and MRI findings were suggestive of concordant cervical and endometrial cancer. Although histopathologic confirmation is necessary for final diagnosis, MRI and FDG PET CT studies may aid in the differential diagnosis. A metastatic cervical mass

    Full Text Available El 66% de los adultos experimenta dolor cervical a lo largo de su vida y el 54% lo ha experimentado durante los pasados 6 meses. Sólo el 5% presentará dolor crónico intenso acompañado de incapacidad funcional. El 80% del dolor cervical se produce por lesiones óseas o musculares como consecuencia de la degeneración discal y facetaria, a lo que se pueden sumar agentes externos, como traumatismo, sobrepeso, sobrecargas laborales, estrés, etc. El diagnóstico del dolor cervical se basa, fundamentalmente, en la exploración física y en la clínica del paciente. Ante la presencia de dolor cervical irradiado a nuca, cintura escapulohumeral y miembro superior derecho sin patrón radicular con exploración positiva en carillas articulares, están indicados los bloqueos diagnóstico-terapéuticos de éstas. En el trabajo se describe la anatomía de la región cervical, cuyo conocimiento es imprescindible tanto para garantizar los buenos resultados, como para minimizar los riesgos, así como las indicaciones y práctica de la técnica.Cervical pain is experienced by 66% of adults during their lifetime and by 54% in the previous 6 months. Only 5% will experience intense chronic pain with functional disability. Eighty percent of cervical pain is produced by skeletal or muscular lesions as a result of disc and facet degeneration. External causative agents include trauma, overweight, occupational demands, stress, etc. Diagnosis of cervical pain is mainly based on physical examination and clinical findings. In cervical pain radiating to the neck, scapulohumeral girdle and upper right arm without a radicular pattern and positive examination of the facet joints, diagnostic-therapeutic facet joint blocks are indicated. The present article describes the anatomy of the cervical region. Knowledge of this region is essential to guarantee good results and to minimize risks. The indications and practical features of the technique are also discussed.

    Full Text Available Epidemiological studies show that human papillomaviruses (HPV are strongly related to cervical cancer and cervical intraepithelial neoplasias (CIN. Unlike the case for women, there are no consistent data on the natural history of HPV in the male population even though these viruses are prevalent in males. We carried out a prospective study to assess the prevalence of HPV in males as well as the factors that determine such infections in 99 male sexual partners of women with CIN. The genitalia of the males were physically examined and subjected to peniscopy for the collection of scrapings which were subjected to the polymerase chain reaction and restriction fragment length polymorphism to detect HPV. Of the 99 males sampled, 54 (54.5% were positive for HPV DNA, 24% of whom presented normal peniscopy, 28% presented evident clinical lesions and 48% isolated lesions consistent with subclinical infection. In the HPV-negative group, 53% showed normal peniscopy, 4% presented evident clinical lesions and 42% isolated lesions consistent with subclinical infection. The study detected a statistically significant association (P < 0.02, Pearson chi-square test between HPV infection and both the mean number of sexual partners which a male had during his life and the mean number of sexual partners in the year prior to testing. Viral types 6 and 11 were most frequently encountered. The study shows that infection with HPV was frequent in male sexual partners of women with CIN.

    Full Text Available Abstract Purpose In this study the influence of moderate or intense physical exercise, alone or in combination with the consumption of a soya product fermented with Enterococcus faecium, on the development of colon cancer induced chemically in rats with 1,2-dimethylhydrazine (DMH, was investigated. Methods Eighty male Wistar SPF rats were randomly allocated to 8 groups (n = 10. One week after the start of the program of product ingestion and/or physical activity, all animals except the controls (group I were injected subcutaneously with 50 mg/kg b.w. of 1,2-dimethylhydrazine (DMH. This procedure was repeated at the end of the second week. At the end of the 6-week experiment, all the animals were euthanized; the colons were removed and numbers of ACF was estimated. Results Twenty-four days after the induction of pre-neoplastic lesions, it was evident that the formation of ACF was not significantly reduced by the ingestion of the fermented product, by intense or moderate physical activity or by a combination of these factors, in comparison with the positive control group of rats (p Conclusion The results reported in this article show that consumption of the fermented soy product described here and the practice of physical exercise (intense or moderate were incapable, separately or combined, of inhibiting the formation of ACF in DMH-induced rats. The intense physical exercise led to an increased number of foci in the colons of these rats and, probably, to greater susceptibility to colorectal cancer.

  16. Therapeutic Vaccination for HPV Induced Cervical Cancers

    2007-01-01

    Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

    Persistent infection with high-risk types of human papillomavirus(HPV) is known to cause cervical cancer; however,additional genetic and epigenetic alterations are required for progression from precancerous disease to invasive cancer.DNA methylation is an early and frequent molecular alteration in cervical carcinogenesis.In this review,we summarize DNA methylation within the HPV genome and human genome and identify its clinical implications.Methylation of the HPV long control region (LCR) and L1 gene is common during cervical carcinogenesis and increases with the severity of the cervical neoplasm.The L1 gene of HPV16 and HPV18 is consistently hypermethylated in invasive cervical cancers and can potentially be used as a clinical marker of cancer progression.Moreover,promoters of tumor suppressor genes (TSGs) involved in many cellular pathways are methylated in cervical precursors and invasive cancers.Some are associated with squamous cell carcinomas,and others are associated with adenocarcinomas.Identification of methylated TSGs in Pap smear could be an adjuvant test in cervical cancer screening for triage of women with high-risk HPV,atypical squamous cells of undetermined significance,or low grade squamous intraepithelial lesion (LSIL).However,consistent panels must be validated for this approach to be translated to the clinic.Furthermore,reversion of methylated TSGs using demethylating drugs may be an alternative anticancer treatment,but demethylating drugs without toxic carcinogenic and mutagenic properties must be identified and validated.

    In 93 patients with classical chronic polyarthritis (rheumatoid arthritis) (at least five ARA-criterias) there were inflammatory lesions of dens epistropheus in 48.4%, ventral atlantoaxial subluxations in 25.8%, lateral atlantoaxial dislocations in 14% and pseudobasilary invagination in 5.4%. Step-ladder-subluxation between C 2/C 7 was found in 31.2%, discitis in 12.5% and spondylarthritis in 38% of cases. Inflammatory signs of the cervical spine were correlated to the Steinbrocker-Grade IV, ANA level 1 : 40 and the degree of Waaler-Rose. The correlation between long standing steroid-therapy and signs of cervical involvement during c.p. - specially in C/sub 1//C/sub 2/ - is found to be proven. There are connections between the duration of c.p. (more than 10 years) and manifestation of cervical spine lesions, further, in a protective sense between longstanding gold therapy and cervical spine lesions.

    Full Text Available Analysis of the Functional Independence Measure Value of Cervical Spine Injury Patients with Conservative Management. Cervical spine injury is one of the most common spinal cord injuries in trauma patients. From 100,000 spinal cord injury cases reported in the United States of America (2008, sixty seven percent involve cervical spine injury. American Spinal Cord Injury Association (ASIA impairment score is used as an initial assessment but not enough attention prognostic outcome of these patients was paid to. The objective of this study is to analyze the value of functional independence measure (FIM cervical spine injury patients with conservative management and its correlation with age, sex, type of trauma, onset of trauma, cervical abnormalities, type of cervical spine lesion and ASIA impairment score. A prospective cohort study was performed to all patients with cervical spine injury treated inNeurosurgery Department of Dr. Hasan Sadikin Hospital Bandung that fullfiled the inclusion criteria. The subjects were classified based on age, sex, single/multiple trauma, acute /chronic, cervical abnormalities, complete/incomplete lesion and ASIA impairment score. The FIM examination was performed in Outpatient clinic of Neurosurgery. T-test and chi-square test was done to analyze the data. There were 17 cervical spine injury patients treated in Neurosurgery Department of Dr. Hasan Sadikin Hospital during April 2009–April 2010. The average FIM value of cervical spine injury in those patients is 4+ 1.63 by cohort prospective study. There were no correlation between FIM value with age, sex, type of trauma, onset of trauma and cervical abnormalities. Significant correlations were found between FIM value with type of cervical spine lesion and ASIA impairment score in cervical spine patients. Type of cervical spine lesion and ASIA impairment score have significant correlation with FIM value of patients in 6 months after cervical injury.

    Full Text Available CONTEXT AND OBJECTIVE: Cervical stenosis is a postoperative complication of procedures for treating preinvasive lesions of the cervix and takes on particular importance due to the clinical repercussions associated with it. Furthermore, it causes limitations in relation to cytological and colposcopic follow-up. The aim here was to assess the incidence of cervical stenosis among a cohort of patients who underwent electrosurgical conization and to identify possible prognostic factors associated with its occurrence. DESIGN AND SETTING: Retrospective study at Gynecology and Obstetrics Department, Instituto Fernandes Figueira, Rio de Janeiro. METHODS:This was an observational study among a cohort of patients who underwent electrosurgical conization of the uterine cervix. The possible predictive variables were analyzed as bivariate means between the groups with and without stenosis. We also calculated the incidence density rate ratio for cervical stenosis in relation to each possible predictive variable and the respective confidence intervals (95%. Levels of 5% were considered significant. RESULTS: 274 patients who underwent electrosurgical conization of the uterine cervix with a minimum follow-up period of six months were included. The crude incidence of cervical stenosis was 7.66% and the incidence density was 3.3/1,000 patients-month. CONCLUSIONS: We did not find associations between the variables for stenosis. However, we observed borderline significance levels relating to hemorrhagic complications before and after the operation (p = 0.089.

    Pediatric cervical spine injuries have rarely been reported in the setting of child abuse. We report two cases of unsuspected lower cervical spine fracture-dislocation in twin infant girls who had no physical examination findings to suggest cervical spine injury. Classic radio-graphic findings of child abuse were noted at multiple other sites in the axial and appendicular skeleton. Magnetic resonance (MR) imaging proved to be valuable in both the initial evaluation of the extent of cervical spine injury and in following postoperative changes. The unexpected yet devastating findings in these two cases further substantiate the importance of routine evaluation of the cervical spine in cases of suspected child abuse. (orig.)
