    2014-01-01

    Cervical cancer is the tenth most common cancer in women in developed countries that have national screening programs, while it is in the second line in underdeveloped countries. According to Ministry of Health registry data, cervical cancer is the eighth most common cancer among female cancers in Turkey. Today, the most effective screening for cervical cancer is to obtain smears from the cervix. Therefore, periodic screening programs are of great importance in identifying preinvasive lesions...

    Full Text Available The experience of treatment for precancer and early cervical cancer by photodynamic therapy in 12 patients with primary diagnosis H-SIL (CIN II–III and cancer in situ is described. Chlo-rine photosensitizer Photolon was given intravenously at a dose of 0.75–1.15 mg/kg body weight. 2.5 h later the treatment with polyposition laser exposure (light dose – 150 J/cm2, light power density – 400–500 mW/cm2 was made. Thirty days later conization of the cervix with endocervical curettage assessing therapeutic response of cervical tumor tissue was per-formed. According to histological data complete response was in 4 patients, minute foci of CIN I were determined in 7 patients, 1 patient had foci of CIN II. 8 of 10 HPV-positive patients had complete eradication of HPV after treatment. There were no serious adverse events after light exposure. Marked therapeutic response, high anti-viral activity and good feasibility allow to consider photodynamic therapy as alternative organ-sparing treatment of early cancer and pre-cancer of cervix.

    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

    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.

  7. Nuclear expression of Rac1 in cervical premalignant lesions and cervical cancer cells

    International Nuclear Information System (INIS)

    Abnormal expression of Rho-GTPases has been reported in several human cancers. However, the expression of these proteins in cervical cancer has been poorly investigated. In this study we analyzed the expression of the GTPases Rac1, RhoA, Cdc42, and the Rho-GEFs, Tiam1 and beta-Pix, in cervical pre-malignant lesions and cervical cancer cell lines. Protein expression was analyzed by immunochemistry on 102 cervical paraffin-embedded biopsies: 20 without Squamous Intraepithelial Lesions (SIL), 51 Low- grade SIL, and 31 High-grade SIL; and in cervical cancer cell lines C33A and SiHa, and non-tumorigenic HaCat cells. Nuclear localization of Rac1 in HaCat, C33A and SiHa cells was assessed by cellular fractionation and Western blotting, in the presence or not of a chemical Rac1 inhibitor (NSC23766). Immunoreacivity for Rac1, RhoA, Tiam1 and beta-Pix was stronger in L-SIL and H-SIL, compared to samples without SIL, and it was significantly associated with the histological diagnosis. Nuclear expression of Rac1 was observed in 52.9% L-SIL and 48.4% H-SIL, but not in samples without SIL. Rac1 was found in the nucleus of C33A and SiHa cells but not in HaCat cells. Chemical inhibition of Rac1 resulted in reduced cell proliferation in HaCat, C33A and SiHa cells. Rac1 is expressed in the nucleus of epithelial cells in SILs and cervical cancer cell lines, and chemical inhibition of Rac1 reduces cellular proliferation. Further studies are needed to better understand the role of Rho-GTPases in cervical cancer progression

  8. Percutaneous vertebroplasty for metastatic lesions of the cervical spine

    International Nuclear Information System (INIS)

    Objective: To assess the safety and effectiveness of percutaneous vertebroplasty (PVP) performed via three different routes for the treatment of osteolytic metastatic lesions of the cervical spine. Methods: A total of 36 patients with osteolytic cervical metastases (57 cervical vertebrae involved) received the treatment of the PVP. The clinical data were retrospectively analyzed. The WHO standards and visual analogue scale (VAS) were assessed before and after the operation, and the application of three operative accesses (anterolateral approach, lateral approach and anterolateral approach through disc space) was discussed. Results: The puncturing accesses used in three groups were anterolateral approach, lateral approach and anterolateral approach through disc space. The whole procedure, including puncturing and injection of bone cement, was successfully accomplished for all diseased cervical vertebral bodies. All patients were followed up for three months. Of 32 patients who had complete clinical data, complete remission (CR) was obtained in 11, partial remission (PR) in 20, mild remission (MR) in one and no remission (NR) in zero. The clinical effectiveness (CR + PR) was 97%. The VAS scores before operation as well as 24 hours, one week and 3 months after the operation were separately determined, and four groups of data were obtained. Statistically significant difference in VAS scores existed between each other of the above four data groups (P<0.05). A little bone cement leakage was observed in 17 vertebral bodies (29.82%), however, no serious clinical complications occurred. Conclusion: Percutaneous vertebroplasty via anterolateral approach is a safe and effective technique for the treatment of osteolytic metastases located at lower cervical vertebrae (C4-C7). While in treating metastatic lesions invaded the vertebra of C1, PVP via lateral approach should be employed. For C2 and C3 vertebral involvement, PVP via anterolateral approach through disc space should

    Spine fractures in patients with ankylosing spondylitis frequently extend to all 3 columns, which can lead to displacement and deformity with severe instability. Cervical spine fractures occasionally cause severe kyphotic deformities, such as chin-on-chest deformities. In such cases, the patients typically exhibit a chronic progression of hyperkyphosis after the traumatic event. This article describes a unique case of ankylosing spondylitis associated with an acute chin-on-chest deformity following a spine fracture due to a vertebral locking lesion.A 60-year-old man fell while walking and sustained a compression fracture of the C6 vertebra. Two weeks later, the patient acutely developed an inability to raise his head, difficulties with chewing and swallowing, and a horizontal gaze. Radiographs demonstrated a severe kyphosis in the cervical spine with a locking lesion between the anterior wall of the C5 and C6 vertebrae. The patient also presented with neurological impairment in his hands. Because the anterior approach to the spine was anatomically impossible, halo traction was initially applied under a close observation of neurological symptoms. Three days after halo traction, release of the vertebral locking lesion and realignment of the spine were seen. The patient subsequently underwent spinal fusion using a combined anterior-posterior approach.Postoperatively, neurological dysfunction improved, and solid fusion was confirmed at 6 months. In cases of acute kyphotic deformity following cervical spine fracture in ankylosing spondylitis patients, halo traction followed by circumferential spine fusion is a safe and effective approach for improving the alignment and stability of the spine.

    Increased expression of viral E6 and E7 oncoproteins within the host cells results in an increase in cellular protein p16INK4a expression. That increase may serve as a marker for dysplastic and neoplastic cells of the uterine cervical epithelium. The aim of this study is to assess the p16INK4a protein expression in different stages of cytological abnormality in correlation with the proven high oncogenic risk human papillomavirus infection in order to demonstrate its value as the diagnostic marker. The study included cervical smear samples of 371 patient in whom the viral typization was done. In 171 patient, during their regular gynaecological examination, along with conventional Pap smear sampling an additional smear was taken. Two hundred cervix brush (Rovers Medical DevicesOss, the Netherlands) samples were obtained and analyzed by the LBC method and the ThinPrep2000 machine. All samples were analyzed cytologically, classified according to the Bethesda system, and immunostained with the p16INK4a-specific monoclonal antibody E6H4 (MTM Laboratories, Heidelberg, Germany). A significant difference is seen in p16 positivity between the cytological diagnosis of a high grade cervical squamous intraepithelial lesion and the group with mild dysplasia (chi2=146,48; D.F.=4; ptechnique renders it suitable for follow-up monitoring as well as for comparison of the cytological results.

    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 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. PMID:27014363

    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 Abstract Background Infection with human papillomavirus (HPV is associated with uterine cervical intraepithelial neoplasia (CIN and invasive cancers (ICC. Approximately 80% of ICC cases are diagnosed in under-developed countries. Vaccine development relies on knowledge of HPV genotypes characteristic of LSIL, HSIL and cancer; however, these genotypes remain poorly characterized in many African countries. To contribute to the characterization of HPV genotypes in Northeastern Tanzania, we recruited 215 women from the Reproductive Health Clinic at Kilimanjaro Christian Medical Centre. Cervical scrapes and biopsies were obtained for cytology and HPV DNA detection. Results 79 out of 215 (36.7% enrolled participants tested positive for HPV DNA, with a large proportion being multiple infections (74%. The prevalence of HPV infection increased with lesion grade (14% in controls, 67% in CIN1 cases and 88% in CIN2-3. Among ICC cases, 89% had detectable HPV. Overall, 31 HPV genotypes were detected; the three most common HPV genotypes among ICC were HPV16, 35 and 45. In addition to these genotypes, co-infection with HPV18, 31, 33, 52, 58, 68 and 82 was found in 91% of ICC. Among women with CIN2-3, HPV53, 58 and 84/83 were the most common. HPV35, 45, 53/58/59 were the most common among CIN1 cases. Conclusions In women with no evidence of cytological abnormalities, the most prevalent genotypes were HPV58 with HPV16, 35, 52, 66 and 73 occurring equally. Although numerical constraints limit inference, findings that 91% of ICC harbor only a small number of HPV genotypes suggests that prevention efforts including vaccine development or adjuvant screening should focus on these genotypes.

    Full Text Available Pap smear (Conventional smear is the most widely used cervical cancer screening test in the world. Negative intraepithelial lesion for malignancy, squamous intraepithelial lesion and cervical cancer remain important health problems for women worldwide. In developing countries like India, there is a great need for mass screening program for cervical lesion. AIMS AND OBJECTIVES To assess the clinician utility of The 2014 Bethesda System Reporting of cervical and vaginal epithelial abnormalities. MATERIAL AND METHODS All the cervical/vaginal cytology smears reported were retrieved and reviewed in the duration from 2007, 2008, 2009 and 2014. RESULTS A total number of 1700 cases of Pap smears were retrieved during period of study, out of which 90.0% were satisfactory for evaluation; 35.5% were within normal limit and 55.6% were NILM. A few (8.14% of the cases were reported as squamous intraepithelial lesion; 0.5% as atypical squamous cells and 0.19% were reported as atypical glandular cells. CONCLUSION Pap smear is a proven tested tool for making an early diagnosis and treating cervical cancer in early stage. Thus, Pap smear is simple, less expensive diagnostics tool suitable for implementation in India.

    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.

    2010-11-01

    Low-grade squamous intraepithelial lesions (LSIL) are frequently found during cervical cancer screening. Usually they are associated with a human papillomavirus (HPV) infection. Does the high-transmission rate of HPV infection to the male partner represent a clinical risk for him? Are preventive measures to be taken to prevent the occurrence of male diseases? More than 80% of all LSIL are associated with HPV infections. The prevalence of HPV infection in males can range up to 40%, with 60% of the male partners of LSIL female patients presenting with penile flat lesions. The spontaneous cure rate for male infections is very high (90% at 5 years) but negative consequences in females (cervical high-grade lesion and cervical cancer) are frequent. Their male counterparts are far rarer but in some patients can require deleterious treatment. Transmission prevention by the use of condoms and circumcision is discussed. The effectiveness of HPV vaccination in this situation has not been validated. PMID:20646823

    Recent studies have shown that CADM1/MAL methylation levels in cervical scrapes increase with severity and duration of the underlying cervical intraepithelial neoplasia (CIN) lesion. Multiple lesions of different histological grades and duration are frequently present on the cervix. To gain more insight into the possible epigenetic heterogeneity and its consequences for the methylation status in cervical scrapes, we performed an exploratory study of CADM1/MAL methylation in different grades of CIN lesions present in women with multiple cervical biopsies. CADM1-M18 and MAL-M1 methylation was assessed using a standardised, multiplex, quantitative methylation specific PCR on 178 biopsies with various grades of CIN in 65 women, and in their corresponding cervical scrapes. CADM1/MAL methylation positivity increased with disease severity, from 5.5% in normal biopsies to 63.3% and 100% in biopsies with CIN3 and cervical cancer, respectively. In the majority (8/9) of women where besides a CIN2/3 lesion a biopsy from normal cervical tissue was present, the CIN2/3 biopsy was CADM1/MAL methylation positive and the normal biopsy was CADM1/MAL methylation negative. A good concordance (78%) was found between CADM1/MAL methylation results on the scrapes and the biopsy with the worst diagnosis, particularly between samples of women with CIN3 and cervical cancer (92% and 100% concordance, respectively). Thus, in women with multiple cervical biopsies, CADM1/MAL methylation increases with severity of the lesion and is lesion-specific. CADM1/MAL methylation status in cervical scrapes appears to be representative of the worst underlying lesion, particularly for CIN3 and cervical cancer. PMID:26219541

    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 Cervical cancer is one of most common cancers among women in the world caused by human papilloma virus infection. It develops in the tissue of cervix which connects upper body of the uterus to the vagina. The types of cancer are squamous cell carcinoma, adeno carcinoma and adeno squamous carcinoma based on location of cervix where cancer develops. In this paper, an automatic detection of squamous cell carcinoma in cervical images based on Discrete Wavelet Transform (DWT and K-Nearest Neighbor (KNN classifier is described. The energy features are extracted from DWT decomposed image of small area of cervical images. Then the features are fed into KNN classifier to classify whether the given area is normal or cancer affected region. The performance of the proposed system is evaluated by using three wavelets namely bi-orthogonal (bior3.7, Daubechies-8(db8 and Symlet (sym8. Experimental results show the performance of db8 with other wavelets that produces 97.22% average accuracy.

    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.

    2011-01-01

    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.

    Full Text Available Objective: The aim of this study is to evaluate the incidence and distribution of cervical lesions and compare characteristics such as parity and age of the women in Mardin province.Material and Method: Pap smears were drawn from the women screened at Mardin Gynecology and Pediatric Diseases Hospital from 2008 to 2011. All cervicovaginal smears were conventional Pap smear samples evaluated according to the 2001 Bethesda system.Results: There were 3.332 patients in total, whose smears showed no lesions in 3.125 patients. The mean age and number of parities of those patients were 37.34±11.25 and 4.78±3.28. There were 207 smears showing any lesions in cervix; ASC-US, ASC-H, LSIL, HSIL, AGC, squamous cell carcinoma and endocervical adenocarcinoma in 151 (72.94%; 16 (7.72%; 20 (9.66%; 8 (3.86%; 10 (4.83%; 1 (0.48% and 1 (0.48% patient, respectively. The mean age and the parities of the patients were 37.63±10.77 years and 4,74±2,92. Although there was no difference between the control and lesion groups, the parity and the age of patients who had ≥4 births in both the control and lesion groups were significantly higher than the patients with parities <4 births (p=0.000. There was no difference within the cervical lesion group comparing the ASC-US group with the total of the other lesions.Conclusion: High parity was one of the risk factor for having a lesion in uterine cervix in this population. This study represents an initial attempt to reflect the prevalence and the distribution of cervical lesions and their relation with the parity rates in the eastern regions in Turkey.

  14. Comparison of MRI pulse sequences for investigation of lesions of the cervical spinal cord

    International Nuclear Information System (INIS)

    Small spinal cord lesions, even if clinically significant, can be due to the low sensitivity of some pulse sequences. We compared T2-weighted fast (FSE), and conventional (CSE) spin-echo and short-tau inversion-recovery (STIR)-FSE overlooked on MRI sequences to evaluate their sensitivity to and specificity for lesions of different types. We compared the three sequences in MRI of 57 patients with cervical spinal symptoms. The image sets were assessed by two of us individually for final diagnosis, lesion detectability and image quality. Both readers arrived at the same final diagnoses with all sequences, differentiating four groups of patients. Group 1 (30 patients, 53 %), with a final diagnosis of multiple sclerosis (MS). Demyelinating lesions were better seen on STIR-FSE images, on which the number of lesions was significantly higher than on FSE, while the FSE and CSE images showed approximately equal numbers of lesions; additional lesions were found in 9 patients. The contrast-to-noise ratio (CNR) of 17 demyelinating lesions was significantly higher on STIR-FSE images than with the other sequences. Group 2, 19 patients (33 %) with cervical pain, 15 of whom had disc protrusion or herniation: herniated discs were equally well delineated with all sequences, with better myelographic effect on FSE. In five patients with intrinsic spinal cord abnormalities, the conspicuity and demarcation of the lesions were similar with STIR-FSE and FSE. Group 3, 4 patients (7 %) with acute myelopathy of unknown aetiology. In two patients, STIR-FSE gave better demarcation of lesions and in one a questionable additional lesions. Group 4, 4 patients (7 %) with miscellaneous final diagnoses. STIR-FSE had high sensitivity to demyelinating lesions, can be considered quite specific and should be included in spinal MRI for assessment of suspected demyelinating disease. (orig.)

    We assessed the prevalence and risk factors for development of non-carious cervical lesions (NCCLs) in children attending special needs schools in India. The participants were 395 children aged 12-15 years with disabilities in learning, communication, physical function, and/or development. A questionnaire was designed in order to collect information on sociodemographic characteristics, oral hygiene practices, dietary habits, and risk factors for NCCLs. The chi-square test, bivariate analysis, and logistic regression analysis were used to analyze the data. Presence of NCCLs was associated with use of toothpowder or other materials for teeth cleaning, use of harder toothbrushes, use of a horizontal scrub technique for toothbrushing, consumption of a vegetarian diet, and greater consumption of lemon. The overall prevalence of NCCLs was 22.7%. Most lesions involved minimal loss of contour or defects health care among children attending special needs schools. PMID:25807907

Material and Method: Five cases of pediatric chondrocutaneous branchial remnants or accessory pinna were included. The ratios of the longest dimensions of the external ear to that of the accessory tragus/chondrocutaneous branchial remnants were calculated. Results: The size and rate of growth of chondrocutaneous branchial remnants or accessory pinna were found to be inversely proportional to the distance between the lesions and the normal pinna. Conclusion: The current literature and norms of terminology dictate that two different terminologies for lesions that are essentially histologically identical should be avoided. Chondrocutaneous branchial remnants, accessory pinna/tragus and chondroid/ cartilaginous choristomas are identical lesions with similar pathogeneses and should be referred to as choristomas.

    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.

  4. Ways of improving three-dimensional CT angiography images of cervical and cerebral vascular lesions

    International Nuclear Information System (INIS)

    We evaluated various ways of improving the image clarity of three-dimensional CT angiography (3D-CTA) for the diagnosis of cervical and cerebral vascular disease in sixty-seven patients (36 males and 31 females). The mean age was 61.4 years, with a rang of 17 to 89 years. The patients were examined with a helical CT scanner (TCT-X vision GX) after intravenous bolus injection of 90 ml nonionic contrast medium (300 mgI/ml) at the rate of 3 ml/sec. Intracranial and cervical 3D-CTA were performed 60 and 12 times, respectively. Our findings were as follows: Reduction of the pre-scanning delay time from 18 to 10 sec after the injection of the contrast medium eliminates much of the cavernous sinus from the image and makes it easier to distinguish the intracavernous internal carotid artery in intracranial 3D-CTA. In cervical 3D-CTA, reduction of the pre-scanning delay time from 15 to 9 sec delays imaging of the jugular vein and makes it easy to distinguish the bifurcation of the common carotid artery. A subtraction image on 3D-CTA is useful for detecting of vascular lesions adjacent to bone, such as lesions on the internal carotid artery. By producing a stereo picture, a closer three-dimensional relationship between the vascular lesion and the vessel circumference organization can be recognized. Vascular lesions can be clearly visualized from inside the artery using a 3D-CT endoscopic image. We were able to obtain a great deal of detailed information from 3D-CTA images with these modifications and we believe they enhance diagnostic accuracy of the technique. (author)

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 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.

    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.

    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

  11. Space-occupying, inflammatory and dyplastic lesions of the cranio-cervical junction seen in nuclear magnetic resonance imaging (MRI)

    International Nuclear Information System (INIS)

    Lesions of the cranio-cervical junction have acquired a special place amongst lesions of the posterior cranial fossa and the upper cervical region. This is due to the unusually long period between the appearance of the first symptoms and reaching a conclusive diagnosis. Frequently such lesions cannot be detected by either normal X-rays or conventional tomographic techniques. The introduction, however, of computer tomography (CT) and, in particular, magnetic resonance imaging (MRI) has made the examination of the critical zone of the cranio-cervical junction much easier and the diagnosis of thee lesions has now become largely dependent upon those techniques. Because soft tissue contrast is intrinsic to MRI this technique, in particular, has made possible substantial improvements in the quality of images of ligaments and soft tissue than those provided by standard CT. In this paper, the advantages which are provided by MRI in the context of the diagnosis of non-bony lesions in the cranio-cervical region are presented and discussed

    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 p16INK4a 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 p16INK4a 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 p16INK4a protein was observed in 72.9% (70/96) of the biopsies. In addition, p16INK4a protein detection was closely correlated with recovery of HR HPV. Our result showed that p16INK4a expression level is correlated with HR-HPV status. PMID:27390742

    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: The aim of this study was to identify human papillomavirus (HPV) in cervical intraepithelial neoplasia (CIN) lesions and to evaluate the persistence of viral DNA after diathermic large loop excision (DLLE) treatment. STUDY DESIGN: Biopsies from 36 patients with low- and high-grade CIN lesions were studied before and after DLLE treatment looking for HPV sequences. DNA was extracted to perform a radioactive polymerase chain reaction (PCR) using GP 5,6 generic primers. PCR products were analyzed by the single-stranded conformational polymorphism (SSCP) which is a simultaneous detection and typing method. Dot-blot hybridization with generic and type-specific biotinylated oligonucleotide probes was applied in some cases. RESULTS: HPV DNA was found in all pretreatment samples, and the viral type was identified in 80% of them, HPV 16 being the most prevalent. The viral type coincided with that detected in the first biopsy in all except one case. Seventy five percent of the patients (27 cases) were negative for CIN at follow up, but 50% of them remained HPV DNA positive. CONCLUSION: DLLE treatment was effective in removing the CIN lesion but not the HPV. This fact points out the need to asses the presence of HPV in DNA during the follow-up, since viral persistence has been considered a high risk factor for recurrence and/or malignant transformation.

  15. CT-diagnosis for mass lesions in the parotid gland and cervical region

    International Nuclear Information System (INIS)

    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.

  16. Urgent stenting for patients with acute stroke due to atherosclerotic occlusive lesions of the cervical internal carotid artery

    International Nuclear Information System (INIS)

    Acute symptomatic occlusion of the cervical internal carotid artery (ICA) can be treated by intravenous administration of tissue plasminogen activator, percutaneous transluminal angioplasty, and carotid endarterectomy. Carotid artery stenting (CAS) is now indicated for cervical ICA stenosis, but the safety and the efficacy of urgent CAS have not been established. We retrospectively reviewed 10 patients treated by urgent CAS for atherosclerotic occlusive lesions of cervical ICA with acute stroke. Five patients had complete occlusions and five had near total occlusions. Five of the 10 patients had intracranial tandem occlusions. Indication for urgent CAS was determined by mismatch of diffusion-weighted and perfusion-weighted magnetic resonance imaging findings. Stents were successfully deployed in all lesions. Three of five patients with concomitant intracranial tandem occlusions were treated by additional intraarterial fibrinolysis after the CAS. Intracranial artery occlusions were completely recanalized in one patient, and partially recanalized in two by fibrinolysis. Hyperperfusion syndrome did not occur in any of the patients. A favorable outcome (modified Rankin Scale ≤1) was obtained in all of the five patients with isolated cervical ICA occlusion and one of the five patients with intracranial tandem occlusions. Urgent CAS is a safe and effective treatment in patients with isolated cervical ICA occlusion. Treatment of intracranial tandem occlusions is an issue that must be resolved. (author)

    Prior to investigating the contraceptive efficacy of cervical caps, we undertook a preliminary study to evaluate potential side effects of these devices. Women who had not previously used a cap were randomly assigned to wear either a Vimule or Cavity Rim Cap (CRC) for as long as seven days. The Vimule cap caused lesions of the portio vaginalis ranging from erythematous impressions to abrasions and frank lacerations. There was variation in the degree of trauma depending, in part, on the size of the cap and duration of wear. Disruption of the epithelium occurred in eight of twelve Vimule users, but the lesions were sometimes difficult to see owing to their location. CRCs were worn by 20 women. This device sometimes left a "suction ring" on the cervix but did not disrupt the epithelium. Two of three long-term users of the Vimule cap who were also studied had unusual formations of the vaginal mucosa suggesting a proliferative reaction to chronic irritation. It is recommended that all women using a Vimule Cap be carefully re-examined and counseled about further use of the device according to the findings of the examination. PMID:7160179

    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-<40 years: prevalence ratio [PR], 2.36; 95% confidence interval [CI], 1.45-3.84, p for trend = 0.001), lower CD4 + cell counts (<100 versus ≥200 cells/mm(3): PR, 1.55; 95% CI, 1.01-2.36, p for trend = 0.03) and 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.

    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.

    VEGF and podoplanin (PDPN) have been identified as angiogenesis and/or lymphangiogenesis regulators and might be essential to restrict tumor growth, progression, and metastasis. In the present study, we evaluate the association between the expression of these markers and CIN grade. Immunohistochemistry was performed in 234 uterine cervical samples using conventional histologic sections or TMA with the monoclonal antibodies to VEGF (C-1 clone) and podoplanin (D2-40 clone). Positive-staining rates of VEGF in 191 CIN specimens were significantly associated with histological grade (P < 0.001). Negative and/or focal immunostaining for PDPN were more frequent in CIN 3 (P = 0.016). We found that patients with CIN 3 more frequently had strong and more diffuse staining for VEGF and diminished staining for PDPN (P = 0.018). Strong and more diffuse VEGF immunoexpressions in CIN 2 and CIN 3 were detected when compared to CIN 1. Negative and/or focal PDPN immunoexpression appear to be more frequent in CIN 3. Moderate to strong VEGF expression may be a tendency among patients with high-grade lesions and diminished PDPN expression. PMID:27313335

    Here, we demonstrate that electroporation-enhanced immunization with a rationally designed HPV DNA vaccine (GX-188E), preferentially targeting HPV antigens to dendritic cells, elicits a significant E6/E7-specific IFN-γ-producing T-cell response in all nine cervical intraepithelial neoplasia 3 (CIN3) patients. Importantly, eight out of nine patients exhibit an enhanced polyfunctional HPV-specific CD8 T-cell response as shown by an increase in cytolytic activity, proliferative capacity and secretion of effector molecules. Notably, seven out of nine patients display complete regression of their lesions and viral clearance within 36 weeks of follow up. GX-188E administration does not elicit serious vaccine-associated adverse events at all administered doses. These findings indicate that the magnitude of systemic polyfunctional CD8 T-cell response is the main contributing factor for histological, cytological and virological responses, providing valuable insights into the design of therapeutic vaccines for effectively treating persistent infections and cancers in humans.

    Background: Cervical cancer is essentially a sexually transmitted disease related to human papillomavirus infection. This disease’s incidence has been globally enhanced, particularly in increasingly younger women. Objective: To determine cervical lesions in women younger than 25 years. Methods: An observational, descriptive and correlational study including 248 patients registered at the Pathological Anatomy Service of the General University Hospital Dr. Gustavo Aldereguía Lima of Cienfuegos was conducted from January to December 2007. It also included the first quarter of 2008. The following variables were analyzed: patient’s age, age at first intercourse, number of sexual partners, type and degree of injury, and reason for attending consultation. Results: Women over 21 years old and those who had had 2 and 3 sexual partners predominated. The main reason for attending consultation was cervicitis (84, 7%. In 22.6% of women grade I intraepithelial neoplasia was detected, while grade II and III were detected in 41, 9% and 33, 1%, respectively. In 90% of younger patients the lesion was malignant. Conclusions: The presence of cervical lesions in women under 25 years is not low and neither is the frequency of malignant lesions.

    Full Text Available Background: Low-grade squamous intraepithelial lesions (LSIL are the earliest lesions of the uterine cervix, the persistence and integration of high-risk human papillomavirus (HR-HPV as type 16, which promotes the development of more aggressive lesions. Aim: To select more aggressive lesions with tendency to progress to invasive cervical cancer. Materials and Methods: A total of 75 cytological specimens in liquid base (Liqui-PREP were analyzed: 25 specimens were with no signs of SIL (NSIL and without HPV; 25 NSIL with HPV-16, and 25 with both LSIL and HPV-16. The expression of Ki-67, telomerase, and viral E6 was evaluated by immunocytochemistry; and the detection of viral DNA was done by polymerase chain reaction (PCR and restriction fragment length polymorphism (RFLPs for genotyping or sequencing of HPV-16. The physical state of HPV-16 was evaluated by in situ hybridization with amplification with tyramide. Results: Of the total group, 58.6% had LSIL associated with persistence and of these 59.3% was associated with integrated state of HPV as intense expression of E6, Ki-67 (P = 0.013, P = 0.055 has except for the expression of telomerase present a non-significant association (P<0.341. Conclusions: Overexpression of E6 and Ki-67 is associated with the integration of HPV-16, favoring viral persistence, and increasing the risk of progression in women with NSIL and LSIL.

Here, we used methylation sensitive-high resolution melting (MS-HRM) analysis to detecting promoter methylation ratios of DAPK1, MGMT and RARB gene in patients with different cervical disease grade. The detection of gene promoter methylation was conducted in two hundred fifty patients’ samples including normal cytology (n=48), cervical intraepithelial neoplasia grade 1 (CIN1, n=54), cervical intraepithelial neoplasia grade 2 (CIN2, n=47), cervical intraepithelial neoplasia grade 3 (CIN3, n=56) and cervical squamous cell carcinomas (SCS, n=45). We found there were a significant positive correlation between the promoter methylation status of DAPK1 and cervical disease grade (P=0.022). In addition, the methylated promoters of DAPK1 combined with MGMT, MGMT combined with RARB, DAPK1 combined with RARB were positive correlated with cervical disease grade (P < 0.05). All three genes promoters methylated were positive correlated with cervical disease grade (P < 0.001). Receiver operating characteristic (ROC) curves was conducted to evaluate whether the three genes methylation could be used to be a potential marker for diagnosing high grade cervical disease (HSIL and SCC). The cutoff values for the methylation rates of all these genes were 0-5%. Regrettably, only the methylation of MGMT combined with DAPK1 gave 43.4% sensitivity and 68.6% specificity. The current results indicated that MS-HRM-based testing for DNA methylations of MGMT plus DAPK1 genes holds some promise for high grade cervical disease screening. PMID:26823825

    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. PMID:25625130

    A number of 66 specimens from female cervical lesions were examined for infection with human papillomavirus (HPV) types 6, 11, 16, and 18 by nucleic acid hybridization in dot-blot techniques and 35 sera were tested by the immunodot-blot technique, in order to detect the presence of anti E4 and E7 HPV protein antibodies. The findings were compared with the histologic diagnosis. Fifty-six per cent of specimens contained HPV DNA sequences. In 47% of specimens from cervical carcinoma, HPV 11 was detected in 4 cases, HPV 16 in 21 cases, and HPV 18 in 7 cases. Serum antibodies against HPV 16 E4 and HPV 16 E7 occurred in all the cases of uterine carcinoma, in 4 of 10 cases of CIN I-II, and in 3 of 5 sera obtained from apparently healthy women. The analysis of risk factors disclosed the early onset of sexual activity, a relatively high number of births and abortions before the age of 22 years, the use of oral oestroprogestative contraceptive agents, the presence in anamnesis of genital infections with bacterial flora--Candida albicans, Trichomonas vaginalis, Chlamydia trachomatis, Mycoplasma, etc. Our results showed that HPV typing by nucleic acid hybridization was useful for differentiating low- from high-risk cervical lesions and also tried to elucidate the risk factors associated with HPV infections and progression to malignancy.

    Abnormal expression and promoter methylation of microRNAs (miRNAs) are common events during cervical carcinogenesis. Worldwide, infection by types 18 and 16 of human papillomaviruses (HPVs) is considered the major risk factor for cervical cancer development. It has been reported that expression of the miRNAs can be deregulated by specific HPV genotypes. In this study we analyzed the promoter methylation of 22 miRNAs and the expression of three miRNAs in 10 non-squamous intraepithelial lesions (Non-SIL) without HPV16 infection, and 7 Non-SIL, 16 low-grade SIL (LSIL) and 16 cervical cancer samples, all with HPV16 infection. The methylation status was determined using Human Cancer miRNA EpiTect Methyl II Signature PCR Array® and the expression of miR-124, miR-218 and miR-193b was determined by qRT-PCR using individual TaqMan assays. Comparisons of groups defined were performed using the Fisher exact test for categorical variables and Mann-Whitney test for continuous variables. A p-value of <0.05 was considered statistically significant. The methylation levels of miR-124-2, miR-218-1, miR-218-2 and miR-34b/c promoters were significantly higher in cervical cancer than in LSIL samples. The methylation levels of miR-193b promoter were significantly lower in cervical cancer than in LSIL samples. The expression of miR-124 and miR-218 was significantly lower in cervical cancer than in LSIL samples. The expression of miR-193b was significantly higher in cervical cancer than in LSIL and Non-SIL samples. Our results suggest that the abnormal promoter methylation and expression of miR-124, miR-218 and miR-193b are common events during cervical carcinogenesis. PMID:26797462

    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.

    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 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.

    Two classes of Human papillomaviruses (HPV) infect the anogenital track: high risk viruses that are associated with risk of cervical cancer and low risk types that drive development of benign lesions, such as condylomas. In the present study, we established quantitative transcriptional maps of the viral genome in clinical lesions associated with high risk HPV16 or low risk HPV6b. Marked qualitative and quantitative changes in the HPV16 transcriptome were associated with progression from low to high grade lesions. Specific transcripts encoding essential regulatory proteins such as E7, E2, E1^E4 and E5 were identified. We also identified intrinsic differences between the HPV6b-associated condyloma transcript map and that of the HPV16-associated low grade CIN specifically regarding promoter usage. Characterization and quantification of HPV transcripts in patient samples thus establish the impact of viral transcriptional regulation on the status of HPV-associated lesions and may therefore help in defining new biologically-relevant prognosis markers.

    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.

    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.

    (1)H nuclear magnetic resonance (NMR)-based metabonomics has been used to characterize the metabolic profiles of cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC). Principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis (OPLS-DA) were used to model the systematic variation related to patients with CIN or CSCC with healthy controls. Potential metabolic biomarkers were identified using database comparisons, and the one-way analysis of variance (ANOVA) test was used to examine the significance of the metabolites. Compared with plasma obtained from the healthy controls, plasma from patients with CIN had higher levels of very-low density lipoprotein (VLDL), acetone, unsaturated lipid and carnitine, together with lower levels of creatine, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine, glycine, acetylcysteine, myo-inositol, choline and glycoprotein. Plasma from patients with CSCC had higher levels of acetate and formate, together with lower levels of creatine, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine and tyrosine compared with the plasma of the healthy controls. In addition, compared with the plasma of patients with CIN, the plasma of CSCC patients had higher levels of acetate, formate, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine, tyrosine, acetylcysteine, myo-inositol, glycoprotein, α-glucose and β-glucose, together with lower levels of acetone, unsaturated lipid and carnitine. Moreover, the profiles showed high feasibility and specificity by statistical analysis with OPLS-DA compared to the Thinprep cytology test (TCT) by setting the histopathological outcome as standard. The metabolic profile obtained for cervical cancer is significant, even for the precancerous disease. This suggests a systemic metabolic response to cancer, which may be used to identify potential early diagnostic biomarkers of the cancer and to establish

    Full Text Available The aim of this study was to evaluate the association between the frequency of micronuclei (MN and the cellular changes detected in the conventional Papanicolaou test. 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.

    Full Text Available Introduction: The Ultrasound Screening Exam for Underlying Lesions (USEFUL was developed in an attempt to establish a role for bedside ultrasound in the primary and preventive care setting. It is the purpose of our pilot study to determine if students were first capable of performing all of the various scans required of our USEFUL while defining such an ultrasound-assisted physical exam that would supplement the standard hands-on physical exam in the same head-to-toe structure. We also aimed to assess the time needed for an adequate exam and analyze if times improved with repetition and previous ultrasound training. Methods: Medical students with ranging levels of ultrasound training received a 25-minute presentation on our USEFUL followed by a 30-minute hands-on session. Following the hands-on session, the students were asked to perform a timed USEFUL on 2-3 standardized subjects. All images were documented as normal or abnormal with the understanding that an official detailed exam would be performed if an abnormality were to be found. All images were read and deemed adequate by board eligible emergency medicine ultrasound fellows. Results: Twenty-six exams were performed by 9 students. The average time spent by all students per USEFUL was 11 minutes and 19 seconds. Students who had received the University of California, Irvine School of Medicine’s integrated ultrasound curriculum performed the USEFUL significantly faster (p< 0.0025. The time it took to complete the USEFUL ranged from 6 minutes and 32 seconds to 17 minutes, and improvement was seen with each USEFUL performed. The average time to complete the USEFUL on the first standardized patient was 13 minutes and 20 seconds, while 11 minutes and 2 seconds, and 9 minutes and 20 seconds were spent performing the exam on the second and third patient, respectively. Conclusion: Students were able to effectively complete all scans required by the USEFUL in a timely manner. Students who have

    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

    Human papillomavirus (HPV) is a necessary cause of cervical cancer and its precursors. Increased expression of high-risk hrHPV viral oncogenes in abnormal cells might increase the expression of p16INK4a. We aimed to determine the role of p16INK4a in detecting hrHPV-transformed epithelial cells in liquid-based cervical cytology, and compared the results with hrHPV DNA testing by realtime polymerase chain reaction (RT-PCR). Fifty-seven cytological samples were tested for p16INK4a immunomarker and hrHPV DNA. Test performance of both tests was determined by comparing sensitivity, specificity and predictive values using available histological follow-up data as gold standard. Of 57 samples, 36 (63.2%) showed immunoreactivity for p16INK4a and 43 (75.4%) were hrHPV-infected. A fairly low concordance rate (k = 0.504) between p16INK4a immunolabelling and hrHPV DNA status was noted. For prediction of cervical intraepithelial neoplasia (CIN) II and worse lesions, p16INK4a had a sensitivity and specificity of 93.5% and 60%; whereas hrHPV DNA testing had a sensitivity and specificity of 100% and 20%. Dual testing by combining p16INK4a and hrHPV showed sensitivity and specificity of 100% and 33.3%. In conclusion, p16INK4a is useful in predicting severity of the cytological abnormalities. Although p16INK4a is more specific but less sensitive than hrHPV in detecting high-grade cervical lesions, a combination of both tests failed to demonstrate significant improvement in diagnostic sensitivity, specificity and predictive value. Larger-scale prospective studies are required to assess further whether this biomarker should be routinely used as primary screening tool independently or in combination with hrHPV testing to improve diagnostic accuracy in cervical cytology.

    Objective:Previous reports have shown that the gene promoter region of retinoic acid receptor β (RARβ) was hypermethylated in cervical carcinoma,implying the inhibition of gene transcription.The aim of this study was to investigate the association of cervical cancer development with the RARβ gene expression at the mRNA and protein level to assess the impact of RARβ as a marker for early detection of the cancer.Methods:We collected 126 cases of formalin fixed and paraffin embedded cervical tissue specimens as well as 37 cases of fresh tissue samples from women with cervicitis,cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC).The RARβ mRNA and protein expression was detected by quantitative RT-PCR and immunohistochemistry,respectively.Results:(1) The mRNA expression of RARβ in CIN and cervical cancer was markedly decreased compared to cervicitis with a statistically very significant difference,but no difference was found between CIN and cervical cancer.(2) RARβ protein was normally expressed in the epithelial cells of cervicitis and partially lost in a few cases,but with the development of cervical lesion pathogenesis and cancer,a significant loss of protein expression was detected in CIN (38%) and CSCC (57%) compared to cervicitis (P < 0.01).Conclusion:The downregulation of RARβ transcription or loss of protein expression is an important indicator of cervical cancer and its precursur lesions.The detection of RARβ expression coupled with aberrant methylation of the gene may become a biomarker for the early prognosis or diagnosis of the cancer.

    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.

    Cervical intraepithelial neoplasia (CIN) is caused by human papillomavirus (HPV) infection and is the precursor to cervical carcinoma. The completion of the HPV productive life cycle depends on the expression of viral proteins which further determines the severity of the cervical neoplasia. Initiation of the viral productive replication requires expression of the E2 viral protein that cooperates with the E1 viral DNA helicase. A decrease in the viral DNA replication ability and increase in the severity of cervical neoplasia is accompanied by simultaneous elevated expression of E6 and E7 oncoproteins. Here we reveal a novel and important role for the HPV16-E2 protein in controlling host cell cycle during malignant transformation. We showed that cells expressing HPV16-E2 in vitro are arrested in prophase alongside activation of a sustained DDR signal. We uncovered evidence that HPV16-E2 protein is present in vivo in cells that express both mitotic and DDR signals specifically in CIN3 lesions, immediate precursors of cancer, suggesting that E2 may be one of the drivers of genomic instability and carcinogenesis in vivo.

    2016-09-01

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

    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. PMID:26655816

    Aims A defective DNA damage response can result in genomic instability (GIN) and lead to transformation to cancer. As p53-binding protein 1 (53BP1) localizes at the sites of DNA double strand breaks (DSBs) and rapidly forms nuclear foci (NF), the presence of 53BP1 NF can be considered to be an indicator of endogenous DSBs reflecting GIN. Our aim was to analyse the presence of DSBs by immunofluorescence for 53BP1 expression in a series of cervical lesions, to evaluate the significance of GIN d...

    23 cases of unstable traumatic lesions of the lower cervical spine, without neurologic complication, were treated over a period of eight years. These cases consisted of eight dislocations, five subluxations, nine fracture-dislocations and one "tear drop" or fracture of the vertebral body. Six cases were treated conservatively and fifteen operatively. Two patients died in skeletal traction while awaiting surgical intervention. The surgical approaches were anterior (6 cases), posterior (8 cases) and combined (1 case). There was one case of transitory neurologic deficit immediately after surgery. One case required re-intervention. Overall they obtained satisfactory osteoligamentary consolidation. PMID:2055985

    Full Text Available Objective: To improve the sensitivity of Human Papillomavirus (HPV detection in plasma from high-grade cervical neoplasia patients (CIN III and cervical cancer (CC evaluating any likely correlation with disease stage.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.

    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.

    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 Women with Human Papilloma Virus (HPV persistence are characterized by high levels of IL-10 at cervix. We have determined whether polymorphisms of IL-10 gene promoter might be associated with increased risk of squamous intraepithelial cervical lesions (SICL and whether exist significative differences of IL-10 mRNA expression at cervix and systemic and serum IL-10 protein between SICL cases and non-Cervical Lesions (NCL. Methods Peripheral blood samples from SICL (n = 204 and NCL (n = 166 were used to detect IL-10 promoter polymorphisms at loci -592A/C (rs1800872, -819C/T (rs1800871, -1082A/G (rs1800896, -1352A/G (rs1800893, by allelic discrimination and to evaluate serum IL-10 protein. Cervical epithelial scrapings from NCL and biopsies from SICLs were used for HPV-typing and to evaluate IL-10 mRNA expression level. The systemic and local IL-10 mRNA expression levels were measured by real time-PCR. Genotypic and allelic frequencies of the selected polymorphisms were analyzed by logistic regression, adjusting by age and HPV-genotype, to determine the association with SICL. Results No significant differences were found between genotype frequencies at loci −819, -1082, and −1352. Individuals carrying at least one copy of risk allele A of polymorphism −592 had a two-fold increased risk of developing SICL [adjusted odds ratio (OR, 2.02 (95% CI, 1.26-3.25, p = 0.003], compared to NCL. The IL-10 mRNA expression and serum IL-10 protein, were significantly higher in SICL cases (p  Conclusions The −592 polymorphism is associated with increased risk of SICL and can serve as a marker of genetic susceptibility to SICL among Mexican women. According to IL-10 levels found in SICL, IL-10 can be relevant factor for viral persistence and progression disease.

    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.

    Full Text Available Background: Objective of current study was to assess the acceptability and feasibility of cervical cancer screening using VIA, and treatment of precancerous lesions using cryotherapy in low resource settings Methods: 526 women from three primary health centers of Shinor taluka (population based approach and 250 women of Medical College, Vadodara (facility based approach were sensitized and screened for cervical cancer. Visual Inspection with Acetic acid (VIA was performed as the screening test. In the population based approach, VIA positive women were referred to a Community Health Centre (CHC for colposcopy and biopsy. Ablative treatment in the form of cryotherapy was offered. Patients requiring higher forms of treatment were referred to medical college, Vadodara. In the facility based approach, VIA positive women underwent colposcopy. Guided biopsy was performed in those with positive lesions on colposcopy. Cryotherapy was offered in the same sitting. Those not suitable for cryotherapy were offered loop electrosurgical excision procedure. Women found to have invasive cancer were offered definitive management. Results: VIA positivity rate was 18.8% in the population based approach and 27.2% in the facility based approach.58.8% women in the population based approach and 77.77% women in the facility based approach were treated with cryotherapy on the same day as screening and none reported any severe side effects. Dropout rate in the community approach was 32.32% whereas in the facility it was 0.4%. Conclusions: VIA and cryotherapy procedures were well tolerated by all screened women.

    International Nuclear Information System (INIS)

    Aim: This prospective study is to compare the results of primary (recurrence) and metastatic lesions detection, based on pathologic results, with computed tomography (CT) and/or magnetic resonance imaging (MRI) and positron emission tomography (PET) with [18F]-fluoro-2-deoxy-D-glucose (FDG) in invasive cervical cancer (ICC). Materials and Methods: An FDG PET scan was performed in 136 patients with ICC (107 squamous cell carcinoma [SCC], 18 adenocarcinoma [AdenoCa], 5 adeosquamous cell carcinoma, 4 small cell carcinoma, and 2 poorly differentiated carcinoma; from FIGO staging IB to IVB prior to operation). CT and/or MRI image were performed within one week before or after FDG PET scan was done. The accuracy of lymph node status was based on histological result or a second FDG PET combined with a CT and/or MRI image images. Results: Totally, 68 main tumor and 147 metastatic lesions were recognized by either histopathology or a follow up study. On a lesion basis, CT and/or MRI image images demonstrated 63 (92.6 %) main tumor and 103 (70.1 %) metastatic lesions. For lymph node metastatic lesions detection, there were 6(75 %) enlarged inguinal lymph nodes, 38(76 %) enlarged pelvic lymph nodes (PLN), 28(73.7 %) enlarged para-aortic lymph nodes (PAN), 8(50 %) enlarged supraclavicular lymph nodes (SLNs), and 5(62.5 %) enlarged mediastinal lymph nodes (MLNs). Liver metastases were found in 4(100 %), in lung in 7(70 %) and in bone in 5(83.3 %). Peritoneal metastases were found in 2(28.6 %). FDG PET demonstrated 63 (92.6 %) and 135 (91.8 %) metastatic lesions. For lymph node metastases, FDG PET found 8(100 %) enlarged inguinal lymph nodes, 44(88 %) enlarged PLNs, 36(94.7 %) enlarged PANs, 15(93.8 %) enlarged SLNs, and 8(100 %) enlarged MLNs. Liver metastases were found in 4(100 %), in lung in 9(90 %) and in bone in 6(100 %). Peritoneal metastases were found in 5(71.4 %). On a patient basis, with FDG PET scan, 31(22.8%) were upstaging while 4(2.9%) were down staging. 35

    Fanconi anemia (FA) is a rare genetic disorder caused by defects in DNA damage repair. FA patients often develop squamous cell carcinoma (SCC) at sites where high-risk human papillomaviruses (HPVs) are known to cause cancer, including the cervix. However, SCCs found in human FA patients are often HPV negative, even though the majority of female FA patients with anogenital cancers had preexisting HPV-positive dysplasia. We hypothesize that HPVs contribute to the development of SCCs in FA patients but that the continued expression of HPV oncogenes is not required for the maintenance of the cancer state because FA deficiency leads to an accumulation of mutations in cellular genes that render the cancer no longer dependent upon viral oncogenes. We tested this hypothesis, making use of Bi-L E7 transgenic mice in which we temporally controlled expression of HPV16 E7, the dominant viral oncogene in HPV-associated cancers. As seen before, the persistence of cervical neoplastic disease was highly dependent upon the continued expression of HPV16 E7 in FA-sufficient mice. However, in mice with FA deficiency, cervical cancers persisted in a large fraction of the mice after HPV16 E7 expression was turned off, indicating that these cancers had escaped from their dependency on E7. Furthermore, the severity of precancerous lesions also failed to be reduced significantly in the mice with FA deficiency upon turning off expression of E7. These findings confirm our hypothesis and may explain the fact that, while FA patients have a high frequency of infections by HPVs and HPV-induced precancerous lesions, the cancers are frequently HPV negative. IMPORTANCE  : Fanconi anemia (FA) patients are at high risk for developing squamous cell carcinoma (SCC) at sites where high-risk human papillomaviruses (HPVs) frequently cause cancer. Yet these SCCs are often HPV negative. FA patients have a genetic defect in their capacity to repair damaged DNA. HPV oncogenes cause an accumulation of DNA

    Analytical and clinical performance validation is essential before introduction of a new human papillomavirus (HPV) assay into clinical practice. This study compares the new BD Onclarity HPV assay, which detects E6/E7 DNA from 14 high-risk HPV types, to the Hybrid Capture II (HC2) HPV DNA test, to concurrent cytology and histology results, in order to evaluate its performance in detecting high-grade cervical lesions. A population of 567 women, including 325 with ≥ASCUS (where ASCUS stands for atypical cells of undetermined significance) and any HC2 result and 242 with both negative cytology and negative HC2 results, were prospectively enrolled for the study. The overall agreement between Onclarity and HC2 was 94.6% (95% confidence intervals [CI], 92.3% to 96.2%). In this population with a high prevalence of disease, the relative sensitivities (versus adjudicated cervical intraepithelial neoplasia grades 2 and 3 [CIN2+] histology endpoints) of the Onclarity and HC2 tests were 95.2% (95% CI, 90.7% to 97.5%) and 96.9% (95% CI, 92.9% to 98.7%), respectively, and the relative specificities were 50.3% (95% CI, 43.2% to 57.4%) for BD and 40.8% (95% CI, 33.9%, 48.1%) for HC2. These results indicate that the BD Onclarity HPV assay has sensitivity comparable to that of the HC2 assay, with a trend to an increased specificity. Moreover, as Onclarity gives the chance to discriminate between the different genotypes, we calculated the genotype prevalence and the absolute risk of CIN2+: HPV 16 was the most prevalent genotype (19.8%) with an absolute risk of CIN2+ of 77.1%.

    Breast cancer is the most common form of cancer in women. Early diagnosis can significantly improve lifeexpectancy and allow different treatment options. Clinicians favor 2D ultrasonography for breast tissue abnormality screening due to high sensitivity and specificity compared to competing technologies. However, inter- and intra-observer variability in visual assessment and reporting of lesions often handicaps its performance. Existing Computer Assisted Diagnosis (CAD) systems though being able to detect solid lesions are often restricted in performance. These restrictions are inability to (1) detect lesion of multiple sizes and shapes, and (2) differentiate between hypo-echoic lesions from their posterior acoustic shadowing. In this work we present a completely automatic system for detection and segmentation of breast lesions in 2D ultrasound images. We employ random forests for learning of tissue specific primal to discriminate breast lesions from surrounding normal tissues. This enables it to detect lesions of multiple shapes and sizes, as well as discriminate between hypo-echoic lesion from associated posterior acoustic shadowing. The primal comprises of (i) multiscale estimated ultrasonic statistical physics and (ii) scale-space characteristics. The random forest learns lesion vs. background primal from a database of 2D ultrasound images with labeled lesions. For segmentation, the posterior probabilities of lesion pixels estimated by the learnt random forest are hard thresholded to provide a random walks segmentation stage with starting seeds. Our method achieves detection with 99.19% accuracy and segmentation with mean contour-to-contour error lesions.

    Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Ident...

    Despite the fact that one-step adhesives are currently used routinely in clinical practice, long-term studies on their clinical performance are scarce. The objective of this randomized controlled clinical trial was to test the hypothesis that a 2-hydroxyethyl methacrylate (HEMA)-free one-step self-etch adhesive performs worse than a conventional multistep etch-and-rinse adhesive. Two-hundred and seventy-six non-carious cervical lesions in 52 patients were restored with a micro-hybrid composite (Gradia Direct; GC). These restorations were bonded in random order either with the HEMA-free one-step adhesive G-Bond (GC) or with the 'gold-standard' (control) three-step adhesive Optibond FL (Kerr). The restorations were evaluated after 6, 12, 24, and 36 months of clinical service regarding retention, marginal adaptation, microleakage, caries occurrence, and sensitivity. After a medium-long period of 3 yr, similar success in clinical performance was observed for the simplified all-in-one adhesive and the conventional three-step adhesive. However, the one-step adhesive exhibited significantly more incisal marginal defects and discolorations. Whereas marginal degradation appeared to arrest for the multistep etch-and-rinse adhesive after 12 months, the enamel margins of the restorations bonded with the one-step self-etch adhesive continued to deteriorate. These incisal marginal defects were, however, small and could easily be removed by polishing. For both adhesives, large and sclerosed lesions appeared to be at higher risk of retention loss.

    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

  10. Correlation between the Volume of a Lesion or Physical Training, and Regression Time, in Congenital Torticollis Patients

    International Nuclear Information System (INIS)

    This study aimed to evaluate any correlation between the volume of a lesion or physical training, and regression time, in congenital torticollis patients. From January 2007 to December 2010, 63 infants and young children underwent neck ultrasound (US), as congenital torticollis was clinically suspected. We statistically analyzed the correlation between the volume of a lesion or physical training and the regression time, when successful regression was defined as no visible lesion on follow-up US, or no palpation of the lesion on clinical follow-up. Among 63 patients, 48 were sonographically diagnosed with congenital torticollis: normal delivery (n 39) and c-sec (n = 9). Among them, 24 were clinically followed up, and 22 showed complete regression. Among 24 patients, 9 underwent physical training, and 7 showed complete regression after physical training. There was a negative correlation between the volume of a lesion and the regression time (p 0.011), but there was no statistical significance between physical training and the regression time (p = 0.15). In congenital torticollis patients, the volume of a lesion was in reverse proportion to the regression time, and physical training may be unhelpful for a decrease in regression time.

  12. Serial type-specific human papillomavirus (HPV) load measurement allows differentiation between regressing cervical lesions and serial virion productive transient infections

    International Nuclear Information System (INIS)

    Persistent high-risk human papillomavirus (HPV) infection is strongly associated with the development of high-grade cervical intraepithelial neoplasia (CIN) or cancer. Not all persistent infections lead to cancer. Viral load measured at a single time-point is a poor predictor of the natural history of HPV infections. However the profile of viral load evolution over time could distinguish nonprogressive from progressive (carcinogenic) infections. A retrospective natural history study was set up using a Belgian laboratory database including more than 800,000 liquid cytology specimens. All samples were submitted to qPCR identifying E6/E7 genes of 18 HPV types. Viral load changes over time were assessed by the linear regression slope. Database search identified 261 untreated women with persistent type-specific HPV DNA detected (270 infections) in at least three of the last smears for a average period of 3.2 years. Using the coefficient of determination (R²) infections could be subdivided in a latency group (n = 143; R² < 0.85) and a regressing group (n = 127; R² ≥ 0.85). In (≥3) serial viral load measurements, serial transient infections with latency is characterized by a nonlinear limited difference in decrease or increase of type-specific viral load (R² < 0.85 and slopes between 2 measurements 0.0010 and −0.0010 HPV copies/cell per day) over a longer period of time (1553 days), whereas regression of a clonal cell population is characterized by a linear (R² ≥ 0.85) decrease (−0.0033 HPV copies/cell per day) over a shorter period of time (708 days; P < 0.001). Using serial HPV type-specific viral load measurements we could for the first time identify regressing CIN2 and CIN3 lesions. Evolution of the viral load is an objective measurable indicator of the natural history of HPV infections and could be used for future triage in HPV-based cervical screening programs

    Cervical intraepithelial neoplasia (CIN) is caused by human papillomavirus (HPV) infection and is the precursor to cervical carcinoma. The completion of the HPV productive life cycle depends on the expression of viral proteins which further determines the severity of the cervical neoplasia. Initiation of the viral productive replication requires expression of the E2 viral protein that cooperates with the E1 viral DNA helicase. A decrease in the viral DNA replication ability and increase in th...

    Background: To define the spectrum of human papillomavirus (HPV) types and establish an age limit for triage HPV testing in atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesion (LSIL). Materials and methods: 343 liquid-based cytological samples from the population-based screening programme with minor abnormalities were subjected to HPV genotyping (Linear Array, Roche, Basel, Switzerland). Results: High-risk human papillomavirus (HR-HPV) was found in 71% of LSIL and 49% of ASCUS cases (P<0.001). High-risk human papillomavirus prevalence was age-dependent in LSIL (P=0.01), with decreasing prevalence until the age of 50 years, followed by a slight increase. Human papillomavirus type 16 was the most common HR-HPV, found in 23% of HPV-positive women. Human papillomavirus type 18 was the sixth most common, found in 9.9% (P<0.001). An age-dependent quadratic trend was observed for multiple infections (P=0.01) with a trough at about 42 years. The most common HR-HPV types to show a coinfection with HPV16 (clade 9) were HPV39 (28%), 45 (38%), and 59 (46%), belonging to HPV18 clade 7. The frequency of low-risk (LR) vs probable HR and HR-HPV also followed an age-dependent quadratic trend. Conclusions: After the age of 25 years, HR-HPV prevalence is similar in LSIL and ASCUS cases, motivating a low age limit for triage HPV testing. Multiple infections and LR/HR-HPV dominance are age-dependent. Genotyping in longitudinal design is needed to elucidate the importance of multiple infections in cancer progression and in cross-protection from vaccination. PMID:19623178

    2016-02-01

    Stratified mucin-producing intraepithelial lesion (SMILE) is a cervical intraepithelial lesion, distinct from conventional squamous or glandular counterparts, believed to arise from embryonic cells at the transformation zone by transdifferentiation during high-risk HPV-associated carcinogenesis. It is characterized by stratified, immature epithelial cells displaying varying quantities of intracytoplasmic mucin throughout the majority of the lesional epithelium. We identified a distinct form of invasive cervical carcinoma with morphologic features identical to those in SMILE, which we have termed "invasive stratified mucin-producing carcinoma." Fifteen cases from 15 patients (mean 36 y; range, 22 to 64 y) were retrieved from the pathology archives of multiple institutions with a diagnosis of either SMILE or invasive cervical carcinoma with a description or comment about the invasive tumor's resemblance to SMILE. Seven cases had solely intraepithelial disease with a component of SMILE (mean 29 y; range, 22 to 40 y). The 8 other cases had invasive stratified mucin-producing carcinoma (mean 44; range, 34 to 64 y) in which SMILE was identified in 7. All cases of invasive stratified mucin-producing carcinoma demonstrated stratified, immature nuclei with intracytoplasmic mucin, which morphologically varied between cases from "mucin-rich" to "mucin-poor" in a similar manner to SMILE. All cases had mitotic figures and apoptotic debris, and an intralesional neutrophilic infiltrate was seen in the majority of cases. In cases of invasive carcinoma, the depth of invasion ranged from growth patterns. Given that SMILE is well rooted as a distinct intraepithelial lesion, we propose "invasive stratified mucin-producing carcinoma" to describe its corresponding form of invasive carcinoma.

  9. Augmented serum level of major histocompatibility complex class I-related chain A (MICA) protein and reduced NKG2D expression on NK and T cells in patients with cervical cancer and precursor lesions

    International Nuclear Information System (INIS)

    Cervical cancer is the second most common cancer in women worldwide. NK and cytotoxic T cells play an important role in the elimination of virus-infected and tumor cells through NKG2D activating receptors, which can promote the lysis of target cells by binding to the major histocompatibility complex class I-related chain A (MICA) proteins. Increased serum levels of MICA have been found in patients with epithelial tumors. The aim of this study was to compare the levels of soluble MICA (sMICA) and NKG2D-expressing NK and T cells in blood samples from patients with cervical cancer or precursor lesions with those from healthy donors. Peripheral blood with or without heparin was collected to obtain mononuclear cells or sera, respectively. Serum sMICA levels were measured by ELISA and NKG2D-expressing immune cells were analyzed by flow cytometry. Also, a correlation analysis was performed to associate sMICA levels with either NKG2D expression or with the stage of the lesion. Significant amounts of sMICA were detected in sera from nearly all patients. We found a decrease in the number of NKG2D-expressing NK and T cells in both cervical cancer and lesion groups when compared to healthy donors. Pearson analysis showed a negative correlation between sMICA and NKG2D-expressing T cells; however, we did not find a significant correlation when the analysis was applied to sMICA and NKG2D expression on NK cells. Our results show for the first time that high sMICA levels are found in sera from patients with both cervical cancer and precursor lesions when compared with healthy donors. We also observed a diminution in the number of NKG2D-expressing NK and T cells in the patient samples; however, a significant negative correlation between sMICA and NKG2D expression was only seen in T cells

  10. CCR2-V64I polymorphism is associated with increased risk of cervical cancer but not with HPV infection or pre-cancerous lesions in African women

    International Nuclear Information System (INIS)

    Cervical cancer, caused by specific oncogenic types of human papillomavirus (HPV), is the second most common cancer in women worldwide. A large number of young sexually active women get infected by HPV but only a small fraction of them have persistent infection and develop cervical cancer pointing to co- factors including host genetics that might play a role in outcome of the HPV infection. This study investigated the role of CCR2-V64I polymorphism in cervical cancer, pre-cancers and HPV infection in South African women resident in Western Cape. CCR2-V64I polymorphism has been previously reported to influence the progression to cervical cancer in some populations and has also been associated with decreased progression from HIV infection to AIDS. Genotyping for CCR2-V64I was done by PCR-SSP in a case-control study of 446 women (106 black African and 340 mixed-ancestry) with histologically confirmed invasive cervical cancer and 1432 controls (322 black African and 1110 mixed-ancestry) group-matched (1:3) by age, ethnicity and domicile status. In the control women HPV was detected using the Digene Hybrid Capture II test and cervical disease was detected by cervical cytology. The CCR2-64I variant was significantly associated with cervical cancer when cases were compared to the control group (P = 0.001). Further analysis comparing selected groups within the controls showed that individuals with abnormal cytology and high grade squamous intraepitleial neoplasia (HSIL) did not have this association when compared to women with normal cytology. HPV infection also showed no association with CCR2-64I variant. Comparing SIL positive controls with the cases showed a significant association of CCR2-64I variant (P = 0.001) with cervical cancer. This is the first study of the role of CCR2-V64I polymorphism in cervical cancer in an African population. Our results show that CCR2-64I variant is associated with the risk of cervical cancer but does not affect the susceptibility to HPV

    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.

    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. PMID:980212

    Full Text Available 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 1 and 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.

    Full Text Available The early screening of a precancerous lesion that can develop spontaneously into a cancerous lesion thatis first non-invasive and then invasive. Materials and methods. The study group was made of 1485 patients who were hospitalized between 2001 and 2009 in the Section of Obstetrics and Gynecology of ?Sf. Apostol Andrei? Emergency Hospital in Gala?i. The patients filled in a questionnaire on a sheet of paper in a freely consented way and they were diagnosed with cervical cancer by a cytologic and colposcopic examination, biopsy and other complementary examinations. Results and discussions. It is obvious that, even if cervical carcinoma benefits now from a remarkable methodology of detecting the early forms and even the precursor lesions, in our country this lesion has an importantfrequency and even represents a public health issue with important social-economic implications; in most cases it affects people in full physical and procreative activity; it implies a laborious therapy, long time hospitalization and high costs. The risk of getting infected with HPV(human papilloma virus is at least 50% for the sexually active people for the rest of their lives. Although most infections eliminate with the help of our own immunity, the people who are infected are not aware of HPV presence and they can spread the virus. When our own immune system cannot eliminate the infection, thepersistence of the viral oncogenic strains from the cervical mucosa can lead to the appearance of precancerous lesions.The cytological examination is a simple and fast method that is also cheap and reliable being considered the mosteffective technique for preventing and detecting the precancerous conditions of the cervix, which, treated correctly, canoffer a primary prevention of cervical cancer. The diagnostic certainty was accomplished exclusively by histopathologyof the material obtained during biopsy. Conclusions. We consider that the patients with cervical cancer, no matter

    宫颈癌严重威胁女性健康和安全,是导致女性死亡的主要恶性肿瘤之一.近年来我国宫颈癌的发病率正以每年2%~3%的速度增长,因此早期诊断对于预防和治疗宫颈癌具有决定性的意义.p16INK4a是近年来发现的肿瘤抑制基因,是一种细胞周期蛋白D依赖性激酶的抑制剂,研究表明p16INK4a的表达与宫颈癌的发生发展密切相关.目前宫颈癌筛查中的细胞学检查及hr-HPV检测方法 都具有一定的局限性,寻求新的筛查方法 已成为研究热点.p16INK4a的检测技术易于普及、操作简便,不仅能提高宫颈癌的早期诊断率、预测宫颈癌的发生发展,且较HC-Ⅱ检测更能区分是否存在病变,从而降低传统宫颈癌筛查的假阳性率及假阴性率,提高筛查的灵敏度和特异度,为宫颈癌的筛查开辟了新途径,值得进一步深入研究.%Cervical cancer was a serious threat to women's health and safety , which was the leading cause of cancer death for women. In recent years,the incidence of cervical cancer increased 2% -3% per year in China,so an early diagnosis to prevent cervical cancer and the treatment was of decisive importance. As a tumor suppressor gene,pl6INK4a was a recently discovered inhibitor of cyclin D-dependent kinase; studies had shown that the expression of pl6INK4a was closely linked to the development of cervical cancer. Current screening of cervical cytology and detection methods hr-HPV had certain limitations,to seek new screening method had become a research hotspot.pl6INK4a detection technology was easy to spread,easy to use,which can not only improve the early diagnosis of cervical cancer to predict the impact of the development of cervical cancer, and was better than the HC- II test to distinguish the existence of the disease,thus reducing false positives traditional cancer screening cervical rate and false negative rates,and improving the sensitivity and specificity of screening for cervical

    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.

    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.

    International Nuclear Information System (INIS)

    Sixty-three patients who had either previously treated primary tumors or unknown primary tumors and developed metastatic cervical adenopathy in their previously untreated necks received the combination of surgery and megavoltage irradiation. Within two years, 12 patients died of intercurrent disease, nine patients died with distant metastastases only, and five patients had disease recur at a primary site. The remaining 37 patients were evaluable for control of neck disease; 26 patients had previous treatment to a primary head and neck cancer that was under control at the time cervical adenopathy was treated; and 11 patients had an unknown primary tumor that was believed to be in the head and neck area. The combination of pre- or postoperative irradiation and surgery controlled neck disease in 86% of the evaluable patients. Because of the extent of neck disease, these patients would have been at a high risk of failure in the treated area if only a single modality of treatment were uognostic variables, in addition to treatment, were pretreatment performance status and pretreatment CEA level.

    The control arm of the phase III VIVIANE (Human PapillomaVIrus: Vaccine Immunogenicity ANd Efficacy; NCT00294047) study in women >25 years was studied to assess risk of progression from cervical HPV infection to detectable cervical intraepithelial neoplasia (CIN). The risk of detecting CIN associated with the same HPV type as the reference infection was analysed using Kaplan–Meier and multivariable Cox models. Infections were categorised depending upon persistence as 6‐month persistent infection (6MPI) or infection of any duration. The 4‐year interim analysis included 2,838 women, of whom 1,073 (37.8%) experienced 2,615 infections of any duration and 708 (24.9%) experienced 1,130 6MPIs. Infection with oncogenic HPV types significantly increased the risk of detecting CIN grade 2 or greater (CIN2+) versus non‐oncogenic types. For 6MPI, the highest risk was associated with HPV‐33 (hazard ratio [HR]: 31.9 [8.3–122.2, p 25 years in this study was similar to that in women 15–25 years in PATRICIA. PMID:26685704

    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

    Assessment of Human papillomavirus (HPV) prevalence and genotype distribution is important for monitoring the impact of prophylactic HPV vaccination. This study aimed to demonstrate the HPV genotypes predominating in pre-malignant and cervical cancers in Northern Ireland (NI) before the vaccination campaign has effect. Formalin fixed paraffin embedded tissue blocks from 2,303 women aged 16-93 years throughout NI were collated between April 2011 and February 2013. HPV DNA was amplified by PCR and HPV genotyping undertaken using the Roche(®) linear array detection kit. In total, 1,241 out of 1,830 eligible samples (68.0%) tested positive for HPV, with the majority of these [1,181/1,830 (64.5%)] having high-risk (HR) HPV infection; 37.4% were positive for HPV-16 (n = 684) and 5.1% for HPV-18 (n = 93). HPV type-specific prevalence was 48.1%, 65.9%, 81.3%, 92.2%, and 64.3% among cervical intraepithelial neoplasias (CIN) Grades I-III, squamous cell carcinomas (SCC) and adenocarcinoma (AC) cases, respectively. Most SCC cases (81.3%) had only one HPV genotype detected and almost a third (32.0%) of all cervical pathologies were HPV negative including 51.9% of CIN I (n = 283), 34.1% CIN II (n = 145), 18.7% of CIN III (n = 146), 7.8% of SCC (n = 5), and 35.7% of AC (n = 5) cases. This study provides important baseline data for monitoring the effect of HPV vaccination in NI and for comparison with other UK regions. The coverage of other HR-HPV genotypes apart from 16 and 18, including HPV-45, 31, 39, and 52, and the potential for cross protection, should be considered when considering future polyvalent vaccines.

    Objective To investigate the influence of two gingival retraction techniques on the periodontium and clinical performance before the restoration of cervical lesion. Methods 150 teeth with cervical lesion of 50 patients were selected. The teeth were divided into 3 groups randomly. In the experiment group, a conventional retraction cord ( Ultrapaks) and a paste-like material (Expasyls) were applied on the buccal aspects of each subject. In the control group, no gingival retraction techniques was applied before restoration and filled directly. Bleeding on probing and the pain were assessed after application. The retention, marginal adaptation, the presence of secondary caries and the GI after one year were evaluated . Data were analysed using Chi-Square and Kruskal - Wallis tests (a = 0. 05). Results There were significant difference between the rates of subjective feeling of the Ultrapaks and Expasyls. Bleeding was only induced by Ultrapaks in five subjects. After one year, the differences between the experimental and control groups in GI and marginal adaptation were of statistical significance ( P < 0.05 ). While there were no significant difference between the two control groups. The retention of the restoration and the presence of secondary caries were not statistically significant among the 3 groups. Conclusion Utilization of gingival retraction techniques before the restoration of cervical lesions can efficiently improve the quality of the restoration and the two gingival retraction methods were not statistically significant. The cordless gingival retraction technique is more easy, feasible, rapid than the retraction cord.%目的 研究在楔状缺损修复前使用两种排龈方法对其牙周组织及充填效果的影响.方法 选择50例全口至少有3个楔状缺损位于龈缘或龈下的患者(150颗患牙),每例患者的患牙随机分为3组,对照组直接树脂修复,实验组分别用ULTRA排龈线,Expusyl排龈膏排龈后再充填.分别

  4. Genetic variations of E6 and long control region of human papillomavirus type 16 from patients with cervical lesion in Liaoning, China

    International Nuclear Information System (INIS)

    High-risk human papillomavirus type 16 (HPV16) is a risk factor for cervical cancer. Previous studies suggest that polymorphisms in the E6 gene or the long control region(LCR)of HPV16 may alter the oncogenic potential of the virus. The aims of this study were to investigate the genetic variations of HPV16 E6 gene and LCR in isolates from Chinese population and correlation of the E6 and LCR polymorphisms with disease status of infected patients. HPV16 positive endocervical specimens were collected from 304 women living in Northeast of China. Sequences of E6 gene and LCR were analyzed by PCR-sequencing. Two lineages were found in the populations, including EUR lineage and As lineage. Based on the HPV16 prototype, the most frequent variation in the E6 gene was T178A/G (48.7%), followed by mutations of G94A (12.2%) and T350G (9.9%). The rank orders of incidence of E6 variations in amino acid were as follows: D25E (46.3%), L83V (9.9%) and H78Y (4.3%). Nucleotide variations in LCR were found in all the 304 isolates from HPV16 positive cervical samples. The most commonly observed LCR variations were the transition replacement G7193T, 7434CIns, G7521A and 7863ADel (100%). The As lineage was associated with HPV persistent infections and with disease status of ≥CIN2,3. The EUR lineage variants showed a negative trend of association with the severity of ≥CIN2,3. Among 41 variations found in LCR, 25 (61.0%) were located at the binding sites for transcription factors. Occurrence of ≥CIN2,3 was significantly associated with the mutations of R10G/L83V in E6 and the C7294T co-variation in LCR, after adjusting for ages of infected patients. Associations between As lineage and HPV persistent infections, and with disease status of ≥CIN2,3, and an association between the EUR lineage and negative trend of association with the severity of ≥CIN2,3 were found in this study. An association between a co-variation of R10G/L83V in E6 and C7294T in LCR and an increased risk for

    An unusual case of myositis ossificans traumatica lesion located in the paraspinal region is reported. Despite the contiguity of the lesion with the cervical vertebrae and ominous appearance of the biopsy material, the history of antecedent trauma and computed tomography findings allowed preoperative accurate diagnosis. To our knowledge, myositis ossificans traumatica located in the cervical paraspinal region is very rare. (orig.) With 4 figs., 16 refs.

  6. Diagnosis of cervical disc disease

    International Nuclear Information System (INIS)

    High resolution CT easily localized lesions including soft tissues of the bone such as disc protrusion and thickening of the yellow ligament. In all cases, myelography demonstrated compression of the nerve roots of the spinal cord which corresponded to CT findings at the level where plain CT revealed a lesion. However, CT metrizamide myelography demonstrated the lesion more clearly than did conventional myelography. CT metrizamide myelography also outlined compression of the nerve roots satisfactorily and demonstrated compressed findings of the spinal cord in the dynamic study. Thus, high resolution CT was useful for screening of cervical disc disease, and CT metrizamide myelography, for identification of lesions of the nerve roots. (Chiba, N.)

    Objective To evaluate the role and significance of HPV genotyping detection and Thinprep cytology test (TCT ) in the diagnosis of cervical precancerous lesions ( mild to moderate epithelial neoplasia ). Methods The findings of HPV genotyping and TCT were analyzed in 401 patients with cervical precancerous lesions ( CIN1-CIN2 ) who had been hospitalized between November 2008 to November 2010. Results The sensitivity of HPV genotyping was significantly higher than that of TCT ( P<0.01 ).TCT combined with HPV genotyping enhanced the detection rate of cervical lesions. Subtypes 16, 52, 58, and 18 of HPV were common in high-risk HPV infection with cervical precancerous lesions. Subtype 16 had a markedly higher rate of occurrence of cervical lesions than subtypes 52 and 58 ( P < 0.01 ). Conclusions High-risk HPV infection is the major pathogenic factor for cervical cancer and precancerous lesions. HPV 16 infection easily leads to cervical lesion. HPV genotyping test combined with Thinprep cytology test can increase the detection rate of cervical precancerous lesions.%目的 评估人乳头瘤病毒(HPV)基因分型检测和液基细胞学检查(TCT)在宫颈轻、中度上皮细胞内瘤变(CIN1-CIN2)中的诊断作用及意义.方法 对我院2008年11月-2010年11月期间401例因宫颈癌前病变(CIN1-CIN2)要求官颈环切的患者的HPV分型基因检测情况与液基细胞学检查结果进行总结分析.结果 HPV的灵敏性较TCT明显增高(P<0.01),TCT和HPV基因分型检测结合能提高宫颈病变的检出率;宫颈癌前病变中HPV感染以高危基因组的16、52、58、18亚型感染多见,HPV16犁感染引起高度病变的几率较HPV52型和HPV58型明显增高(P<0.01).结论 高危HPV感染是宫颈癌及癌前病变发病的主要致病因子,HPV16型感染易导致宫颈高度病变;HPV基因分型检测和液基细胞学检查结合,可以提高宫颈癌前病变的检出率.

    The lateral pectoral nerve (LPN) is commonly injured along with the brachial plexus, but its isolated lesions are rare. Here, we present a case of an isolated LPN lesion confused with cervical radiculopathy. A 41-year-old man was admitted to our clinic because of weakness in his right arm. Previous magnetic resonance imaging (MRI) examination revealed right posterolateral protrusion at the C6-7 level. At the initial assessment, atrophy of the right pectoralis major muscle was evident, and mild weakness of the right shoulder adductor, internal rotator, and flexor muscles was observed. Therefore, electrodiagnostic evaluation was performed, and a diagnosis of isolated LPN injury was made. Nerve injury was thought to have been caused by weightlifting exercises and traction injury. Lateral pectoral nerve injury can mimic cervical radiculopathy, and MRI examination alone may lead to misdiagnosis. Repeated physical examinations during the evaluation and treatment phase will identify the muscle atrophy that occurs 1 or more months after the injury. PMID:25290103

    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.

Fine needle aspiration cytology (FNAC) is a simple, safe, rapid and inexpensive method for establishing the diagnosis of lesions. Metastasis is more common in cervical lymph node and enlarged cervical nodes in an elderly patient must be considered as metastatic until proved otherwise. Methods: Retrospectively, 320 cases of left cervical lymph node FNAC were colle...

    Cervical spondylolysis is a rare condition, and less than 100 cases have been reported in the world literature. Cervical spondylolysis is defined as a well corticated defect in the posterior element of a cervical vertebra. Although the etiology of cervical spondylolysis is unknown, its association with dysplastic changes and spina bifida occulta suggest that the lesion is congenital. Here, we describe the radiographs and CT images of cervical spondylolysis involving four levels in a 9 year old boy.

  5. Cervical metastatic glioblastoma multiforme

    International Nuclear Information System (INIS)

    Glioblastoma multiforme (GBM) is the most common and most malignant primary brain tumour in adults. In spite of the hostile nature of glioblastoma multiforme (GBM), extracranial spread is not a common event. With improving management choices and survival times, reports of extracranial occurrence of GBM have increased. Most commonly these metastases are to the lungs, lymph nodes, neck, skull, scalp, liver, and bones; may be evident on routine follow-up images of the original lesion. Head and neck metastasis of GBM can be debilitating. We present a case of cervical metastasis of GBM and discuss possible mechanisms of extraneural spread of this tumour. (author)

    Full Text Available The approach used until recently concerning the phenomena of dental abfraction points to the conclusion that the cervical area of the tooth, were this type of lesion usually occur, concentrates the stress resulted from the action of the forces applied on various areas on the crown. Moreover, any lesion in the cervical area facilitates the possibility of its advance into the tooth, ultimately fracturing it. Our paper presents a FEM (finite element method study on the results of a mechanical analysis of the phenomena involving the tooth damaged by cervical lesions.

    Thoracic duct cysts are uncommon lesions that most commonly occur in the abdominal and thoracic portion of the thoracic duct: the cervical portion is the rarest location. The main causes of thoracic duct cyst are surgical injuries such as neck dissection and blunt trauma. We report here on a rare case of spontaneous cervical thoracic duct cyst that was noted on ultrasonography and CT. The thoracic duct cyst was confirmed by fine needle aspiration and it was treated by sclerotherapy.

    A markedly increased risk of cervical cancer is known in women immunosuppressed due to AIDS or therapy following organ transplantation. The aim of this review is to determine the association between other conditions affecting the immune system and the risk of cervical cancer. Patients with end......-stage renal disease seem to be at an increased risk of cervical cancer. A higher risk of cervical precancerous lesions was found in patients with some autoimmune diseases; particularly if treated with immunosuppressants. Among behavioral factors weakening the immune system, smoking appeared to strongly...... increase the risk of cervical cancer, while poor diet only moderately increased the risk. It is difficult to determine whether sexually transmitted infections other than human papillomavirus infection are independent risk factors.

    2010-01-01

    Full Text Available Foregut duplication is commonly found in the posterior mediastinum. 10-20% of these anomalies are associated with oesophageal duplication. It can occur in all parts of oesophageal length. Although duplication of cervical oesophagus has been previously reported, but a majority of them were found in thoracic oesophagus. Infants with oesophageal duplication usually manifested by respiratory distress or asymptomatic thoracic mass, casually, detected in X-ray. A 7-month-old infant weighing about 7.5 kg, with the signboard of respiratory distress, fever and nutritional intolerance was admitted to our hospital. Physical examination showed dehydration, stridor, tachypnoea, intercostal retraction and neck stiffness. Plain chest radiogram showed dubious cystic mass in the distal neck. Cervical and chest computed tomography scan showed neck cystic lesion disseminated to posterior mediastinum, probably propagated to the respiratory system. Cystic lesion connected to oesophagus was partially resected, oesophagus was repaired and remaining mucous of a cyst was removed, then gastrostomy tube was applied. Although cervical oesophageal duplication cysts are rare, but they must be considered as one of the differential diagnoses of cervical mass with respiratory distress in infants.

  13. Physics Contributions and Clinical Outcome With 3D-MRI-Based Pulsed-Dose-Rate Intracavitary Brachytherapy in Cervical Cancer Patients

    International Nuclear Information System (INIS)

    Purpose: To assess the physics contributions and clinical outcome with three-dimensional magnetic resonance imaging-guided pulsed-dose-rate (PDR) intracavitary brachytherapy in cervical cancer patients. Methods and Materials: The data from 45 patients with primary locally advanced cervical carcinoma were analyzed. The median tumor cervical volume was 64.0 cm3 (range, 3-178). Of the 45 patients, 24 (53%) had histologic and/or radiologic pelvic involvement. After pelvic with or without para-aortic concomitant chemoradiotherapy, a PDR brachytherapy boost was delivered to a three-dimensional magnetic resonance imaging-based clinical target volume, taking into account the dose-volume constraints for critical organs and optimization of the target volume coverage. Results: At a median follow-up of 26 months (range, 9-47), the 2-year overall survival and disease-free survival rate was 78% and 73%, respectively. At the last follow-up visit, the disease of all patients remained locally controlled. Adding external beam radiotherapy and PDR using the equivalent dose in 2-Gy fractions model, the median dose received by 100% and 90% of the target was 54.4 Gyα/β10 and 63.5 Gyα/β10 for the intermediate-risk clinical target volume and 61.6 Gyα/β10 and 74.9 Gyα/β10 for the high-risk clinical target volume, respectively. Of the 45 patients, 23 and 2 developed acute Grade 1-2 and Grade 3 complications, respectively; 21 patients presented with delayed Grade 1-2 complications. One other patient presented with Grade 3 vesicovaginal fistula. No Grade 4 or greater complications, whether acute or delayed, were observed. Conclusion: Magnetic resonance imaging-guided PDR brachytherapy with optimization integrating the limits of tolerance to critical organs allows for excellent local control rates. Moreover, the present results have confirmed that the ability to optimize dwell times can contribute to an improvement in local control rates with a low level of late side effects.

    Full Text Available Background: Enlarged palpable cervical lymph nodes as a primary presenting sign are very common and may be due to inflammatory lesions and tumors. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. In patients presenting with cervical lymphadenopathy, excision biopsy provides material to establish an early diagnosis. We designed this study in our population for histological evaluation of cervical lymph node biopsies that might be important in the management of these patients. Objective: Histopathological evaluation of different diseases involving the cervical lymph nodes in relation to age and sex of the study population. Materials and Methods: It was a cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. A total of 107 patients were evaluated for specific cause of cervical lymphadenopathy in relation to age and sex. Lymph node biopsies of all patients of both sexes and all age groups were included in the study. Results: Among the 107 subjects 58 (54.2% were males and 49 (45.8% were females with a male to female ratio of 1.2:1. The age of the patients ranged from 2 to 85 years with a mean age of 32.68 ± 18.01 years. Of the 107 lymph node biopsies, 34 cases (31.8% were reactive lymphadenitis, 41 cases (38.3% were tuberculosis, 2 cases (1.9% were non-caseous granuloma, 6 cases (5.6% were Hodgkin lymphoma, 8 cases (7.5% were non-Hodgkin lymphoma, 12 cases (11.2% were metastatic neoplasm and 4 cases (3.7% were other specific lesions. Conclusion: The commonest cause of cervical lymphadenopathy was tuberculosis, followed by reactive lymphadenitis, lymphoma and metastatic neoplasm.

    Full Text Available Abstract Background Worldwide cervical cancer remains a leading cause of mortality from gynecologic malignancies. The link between cervical cancer and persistent infection with HPV has been established. At a molecular level little is known about the transition from the precancerous state to invasive cancer. To elucidate this process, cervical biopsies from human specimens were obtained from precancerous state to stage III disease. Methods Cervical biopsies were obtained from patients with a diagnosis of cervical cancer undergoing definitive surgery or staging operation. Biopsies were obtained from patients with precancerous lesions at the time of their excisional procedure. Control samples were obtained from patients undergoing hysterectomy for benign conditions such as fibroids. Samples were subjected to proteomic profiling using two dimensional gel electrophoresis with subsequent trypsin digestion followed by MALDI-TOF protein identification. Candidate proteins were then further studied using western blotting, immunoprecipitation and immunohistochemistry. Results Annexin A1 and DNA-PKcs were found to be differentially expressed. Phosphorylated annexin A1 was up regulated in diseased states in comparison to control and its level was strongly detected in the serum of cervical cancer patients compared to controls. DNA-PKcs was noted to be hyperphosphorylated and fragmented in cancer when compared to controls. By immunohistochemistry annexin A1 was noted in the vascular environment in cancer and certain precancerous samples. Conclusion This study suggests a probable role for protein tyrosine phosphorylation in cervical carcinogenesis. Annexin A1 and DNA-PK cs may have synergistic effects with HPV infection. Precancerous lesions that may progress to cervical cancer may be differentiated from lesions that will not base on similar immunohistochemical profile to invasive squamous cell carcinoma.

  8. Distracted cervical spinal fusion for management of caudal cervical spondylomyelopathy in large-breed dogs

    International Nuclear Information System (INIS)

    Using an autogenous bone graft (obtained from the iliac crest), 4-mm cancellous bone screws, and polymethylmethacrylate, a distracted cervical spinal fusion technique was performed on 10 dogs with myelographic evidence of caudal cervical spondylomyelopathy. All dogs had evidence of dynamic soft tissue spinal cord compression, as indicated by flexion, extension, and traction myelographic views. Of the 10 dogs, 4 previously had undergone surgery by use of ventral slot or cervical disk fenestration techniques, and their neurologic status had deteriorated after the original surgery. Preoperative neurologic status of the 10 dogs included nonambulatory tetraparesis (n = 5), severe ataxia with conscious proprioceptive deficits (n = 2), and mild ambulatory ataxia with conscious proprioceptive deficits (n = 3). Five dogs had signs of various degrees of cervical pain. Clinical improvement was observed in 8 of 10 dogs--either improved neurologic status or elimination of cervical pain. Implant loosening developed in 3 dogs; 2 of them were euthanatized because of lack of neurologic improvement. Radiographic evidence of bony cervical fusion was observed during a 9- to 24-week period in 6 of the 8 surviving dogs. The distracted cervical fusion technique appears to be a valid surgical procedure to manage cervical spondylomyelopathy in those dogs in which the lesions are limited to one cervical intervertebral disk space

  11. Endometrial cancer with cervical extension mimicking dual concordant endometrial and cervical malignancy by F18 FDG PET and MRI

    International Nuclear Information System (INIS)

    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 from

    2007-03-01

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    2013-01-01

    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.

  19. 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.

    Worldwide, cancer of the cervix is the second leading cause of cancer death in women: each year, an estimated 500,000 cases are newly diagnosed. Among populations, there are large differences in incidence rates of invasive cervical cancer: these reflect the influence of environmental factors, screening Papanicolaou (Pap) tests, and treatment of pre-invasive lesions. The high-risk human papillomavirus (HPV) subtypes 16, 18, 31, 33, and 51 have been recovered from more than 95% of cervical cancers. We have made great strides in understanding the molecular mechanism of oncogenesis of this virus, focusing on the action of the E6 and E7 viral oncoproteins. These oncoproteins function by inactivating cell cycle regulators p53 and retinoblastoma (Rb), thus providing the initial event in progression to malignancy. Cervical cancers develop from precursor lesions, which are termed squamous intraepithelial lesions (SIL) and are graded as high or low, depending on the degree of disruption of epithelial differentiation. Viral production occurs in low-grade lesions and is restricted to basal cells. In carcinomas, viral DNA is found integrated into the host genome, but no viral production is seen. The well-defined pre-invasive stages, as well as the viral factors involved at the molecular level, make cervical carcinoma a good model for investigating immune therapeutic alternatives or adjuvants to standard treatments.

    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.

    The diode laser is today widely used in oral pathology to excise lesions; however, some controversy surrounds laser surgery, specifically the accuracy of pathological diagnosis and the control over thermal tissue damage. This study aimed to establish if physical damage induced by the diode laser could affect the histopathological diagnosis and to evaluate the damage caused to the resection margins. Between 2005 and 2010, at S. Gerardo Hospital, Milan, 608 cases of soft tissue lesions localized in the oral cavity (cheek, gingiva, buccal mucosa, tongue, and lips) were examined. Specimens were excised with an 808-nm diode laser, output 1.6-2.7 W, in continuous-wave mode with fibers of 320 μm. Specimens were fixed in 10% buffered formalin solution and examined separately under an optical microscope by two pathologists. In all of the specimens, changes to the epithelium, connective tissue and blood vessels, shape of incision damage, and overall width of modified tissues were evaluated. The data for specimens larger than 3 mm excised with the diode laser were not significant in terms of stromal changes or vascular stasis, while epithelial and stromal changes were significantly more frequent in specimens with a mean size below 3 mm; the diagnosis was not achievable in 46.15%. Our data show that the diode laser is a valid therapeutic instrument for excising oral lesions larger than 3 mm in diameter, but induces serious thermal effects in small lesions (mean size below 3 mm). However, from a clinical standpoint, it is suggested necessary that the specimens taken have in vivo a diameter of at least 5 mm in order to have a reliable reading of the histological sample.

  5. Cervical spine injury in child abuse: report of two cases

    International Nuclear Information System (INIS)

    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.)

    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.

  9. Two cases of high cervical cord tumor

    International Nuclear Information System (INIS)

    Two cases of high cervical cord tumor are presented. Case 1 is an intradural extramedullary meningioma located at the foramen magnum. Case 2 is an extradural neurinoma originated from left C2 spinal nerve root. In each case high resolution computed tomography and myelography, especially that of axial view, visualized extramedullary mass lesion.FIn recent years it has been stressed that high resolution computed tomography is useful in the diagnosis of high cervical cord lesion, and this idea is quite reasonable from our experiences. On the other hand, it has been mentioned that myelography often gives false negative results as far as high cervical cord lesion is concerned, which is mainly because relative width of the subarachnoid space in the region of the foramen magnum.FOur experience indicated that in myelographic examination of foramen magnum tumor it is advisable to add axial view to ordinary P-A and lateral views. Bacause axial high cervical myelography gives an image similar to computed tomogram of this region, this technique not only increases the diagnostic value of myelography but also, in some cases, substitutes for computed tomography which costs very much.

    Full Text Available Background: Cervical radiculopathy is a dysfunction of nerve root of the cervical spine where C6& C7 nerve roots are the most commonly affected. It encompasses important symptoms other than pain, such as paresthesia, numbness and muscle weakness in dermatomal or myotomal distribution of an affected nerve root. A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy, including mechanical cervical traction, manipulation, therapeutic exercises and TENS. Studies to find out the effectiveness of TENS versus Intermittent Cervical Traction among patients with Cervical Radiculopathy are sparse. Hence the present study was undertaken to find out and compare effectiveness of TENS versus Intermittent Cervical Traction a newer technique towards betterment in treatment of cervical radiculopathy patients. Methodology: 30 patients from Baroda association for the blind (Lions club of Baroda, Subhanpura & Sushrut Physiotherapy Clinic, Akota were chosen based on the inclusion and exclusion criteria. Group A comprised of 15 people with cervical radiculopathy were given TENS with Isometric neck exercises and active neck movements. Group B comprised of 15 people with cervical radiculopathy were given Intermittent Cervical Traction with Isometric neck exercise and active neck movements. VAS Scale & Neck Disability Index (NDI were used as outcome measures pre & post treatment. Results: The pre test evaluation showed that, there is no significant difference (P> 0.05 between the two groups for all the variables measured. The post-test evaluation of both groups showed a very high significance (P< 0.05 within the group for all the outcome measurements. A post-test comparison of measured variables, between the groups showed that the Group A demonstrated a statistically significant (P< 0.05 reduction in pain and Neck Disability Index. Conclusion: From the above study concluded that TENS was more effective

Laboratory data suggest that marijuana could have an immunomodulatory effect. Little is known, however, regarding the effects of marijuana use on cervical HPV or neoplasia. Therefore, we studied the natural history (ie, prevalence, incident detection, clearance/persistence) of cervical HPV and cervical neoplasia (ie, squamous intraepithelial lesions ...

    Abfraction is a type of noncarious cervical lesion (NCCL) characterized by loss of tooth tissues with different clinical appearances. Evidence supports that abfraction lesions, as any NCCLs, have a multifactorial etiology. Particularly, the cervical wear of abfraction can occur as a result of normal and abnormal tooth function and may also be accompanied by pathological wear, such as abrasion and erosion. The interaction between chemical, biological, and behavioral factors is critical and helps to explain why some individuals exhibit more than one type of cervical wear mechanism than others. In an era of personalized dentistry, patient risk factors for NCCLs must be identified and addressed before any treatment is performed. Marked variations exist in dental practice concerning the diagnosis and management of these lesions. The lack of understanding about the prognosis of these lesions with or without intervention may be a major contributor to variations in dentists’ management decisions. This review focuses on the current knowledge and available treatment strategies for abfraction lesions. By recognizing that progressive changes in the cervical area of the tooth are part of a physiologically dynamic process that occurs with aging, premature and unnecessary intervention can be avoided. In cases of asymptomatic teeth, where tooth vitality and function are not compromised, abfraction lesions should be monitored for at least 6 months before any invasive procedure is planned. In cases of abfraction associated with gingival recession, a combined restorative-surgical approach may be performed. Restorative intervention and occlusal adjustment are not indicated as treatment options to prevent further tooth loss or progression of abfraction. The clinical decision to restore abfraction lesions may be based on the need to replace form and function or to relieve hypersensitivity of severely compromised teeth or for esthetic reasons.

    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.

    Full Text Available O papilomavírus humano (HPV é um fator etiológico bem estabelecido para o câncer cervical. Esse vírus de DNA infecta primariamente o epitélio e pode induzir lesões benignas ou malignas na pele e na mucosa. Alguns HPVs são considerados de alto risco, responsáveis pela progressão das lesões precursoras até câncer cervical. A infecção genital pelo HPV é comum em mulheres jovens e geralmente é transitória. Uma pequena proporção de mulheres infectadas desenvolve câncer cervical, implicando o envolvimento de fatores ambientais e fatores genéticos na carcinogênese. Essa revisão aborda a estrutura viral, classificação e patologia do HPV, história natural e fatores de risco para neoplasia cervical e perspectivas futuras com a vacina anti-HPV.Human papillomavirus (HPV has been established as an important etiological factor for the development of cervical cancer. This DNA virus primarily infects the epithelium and can induce benign and malignant lesions of the mucous membranes and skin. Some HPVs are considered high risk due to their role in malignant progression of cervical tumors. Genital HPV infections are common and usually transient among young sexually active women. Only a small fraction of infected women develop cervical cancer, implying the involvement of environmental and genetic cofactors in cervical carcinogenesis. Classification, virology, pathology, natural history, epidemiological features of genital HPV infection, and future prospects for cervical cancer prevention with HPV vaccines will be reviewed here.

    2016-05-01

    Cervical radiculopathy describes pain in one or both of the upper extremities, often in the setting of neck pain, secondary to compression or irritation of nerve roots in the cervical spine. It can be accompanied by motor, sensory, or reflex deficits and is most prevalent in persons 50 to 54 years of age. Cervical radiculopathy most often stems from degenerative disease in the cervical spine. The most common examination findings are painful neck movements and muscle spasm. Diminished deep tendon reflexes, particularly of the triceps, are the most common neurologic finding. The Spurling test, shoulder abduction test, and upper limb tension test can be used to confirm the diagnosis. Imaging is not required unless there is a history of trauma, persistent symptoms, or red flags for malignancy, myelopathy, or abscess. Electrodiagnostic testing is not needed if the diagnosis is clear, but has clinical utility when peripheral neuropathy of the upper extremity is a likely alternate diagnosis. Patients should be reassured that most cases will resolve regardless of the type of treatment. Nonoperative treatment includes physical therapy involving strengthening, stretching, and potentially traction, as well as nonsteroidal anti-inflammatory drugs, muscle relaxants, and massage. Epidural steroid injections may be helpful but have higher risks of serious complications. In patients with red flag symptoms or persistent symptoms after four to six weeks of treatment, magnetic resonance imaging can identify pathology amenable to epidural steroid injections or surgery.

  4. New Molecular Tools for Efficient Screening of Cervical Cancer

    Full Text Available Cytological screening using the Pap-smear led to a remarkable reduction of the mortality of cervical cancer. However, due to subjective test criteria it is hampered by poor inter- and intra-observer agreement. More reproducible assays are expected to improve the current screening and avoid unnecessary medical intervention and psychological distress for the affected women. Cervical cancer arises as consequence of persistent high risk papillomavirus (HR-HPV infections. Expression of two viral oncogenes, E6 and E7, in epithelial stem cells is required to initiate and maintain cervical carcinogenesis and results in significant overexpression of the cellular p16INK4a protein. Since this protein is not expressed in normal cervical squamous epithelia, screening for p16INK4a over-expressing cells allows to specifically identify dysplastic lesions, and significantly reduces the inter-observer disagreement of the conventional cytological or histological tests. Progression of preneoplastic lesions to invasive cancers is associated with extensive recombination of viral and cellular genomes which can be monitored by detection of papillomavirus oncogene transcripts (APOT assay derived from integrated viral genome copies. Detection of integrated type oncogene transcripts points to far advanced dysplasia or invasive cancers and thus represents a progression marker for cervical lesions. These new assays discussed here will help to improve current limitations in cervical cancer screening, diagnosis, and therapy control.

  6. Relationships between radiography of cervical vertebrae and histopathology of the cervical cord in wobbling 19 foals

    International Nuclear Information System (INIS)

    Nineteen wobbling foals (17 males and 2 females) showing lameness of hindlimbs at 6 to 21 months of age were investigated radiographically and histopathologically. Minimum sagittal diameter (MSD), minimum flexion diameter (MFD) and minimum dural sagittal diameter (MDD) were measured on plain radiograms or myelograms taken at neutral and flexed positions as indicators of narrowed vertebral canal. After necropsy, the cervical spines and the spinal cord were examined macroscopically and respectively the relationships between radiographic findings and the corresponding morphological lesions were evaluated. Radiographically, lower values than each minimum reference limits were recorded in 14 foals in MSD, 5 foals in MFD and 6 foals in MDD, respectively. According to the histopathologic examination, the disappearance of axons and myelin sheaths, vacuolated spongy degeneration and appearance of macrophages were recognized symmetrically in the white matter of the cervical cord. These lesions were centrally located at the spinal cord radiographically demonstrated as compressed sites in 12 out of 17 foals examined. Macroscopically, asymmetrical overgrowth of one side of the process, encroachment of articular processes into the intervertebral foramina and proliferation of bone around articular facets were observed in the articular processes of bone specimens in the caudal neck of 6 foals. In conclusion, the equine incoordination might mainly be caused by the cervical stenotic myelopathy resulting from cervical vertebral malformation, and therefore the cervical vertebral radiography, especiallymyelography, is quite very important and effective for the diagnosis of wobbling foals

    Full Text Available Although anterior cervical instrumentation was initially used in cervical trauma, because of obvious benefits, indications for its use have been expanded over time to degenerative cases as well as tumor and infection of the cervical spine. Along with a threefold increase in incidence of cervical fusion surgery, implant designs have evolved over the last three decades. Observation of graft subsidence and phenomenon of stress shielding led to the development of the new generation dynamic anterior cervical plating systems. Anterior cervical plating does not conclusively improve clinical outcome of the patients, but certainly enhances the efficacy of autograft and allograft fusion and lessens the rate of pseudoarthrosis and kyphosis after multilevel discectomy and fusions. A review of biomechanics, surgical technique, indications, complications and results of various anterior cervical plating systems is presented here to enable clinicians to select the appropriate construct design.

    Introduction Cervical intraepithelial neoplasias (CIN) represent precursor lesions of cervical cancer. These neoplastic lesions are traditionally subdivided into three categories CIN 1, CIN 2, and CIN 3, using microscopical criteria. The relation between grades of cervical intraepithelial neoplasia (CIN) and its fractal dimension was investigated to establish a basis for an objective diagnosis using the method proposed. Methods Classical evaluation of the tissue samples was performed by an experienced gynecologic pathologist. Tissue samples were scanned and saved as digital images using Aperio scanner and software. After image segmentation the box counting method as well as multifractal methods were applied to determine the relation between fractal dimension and grades of CIN. A total of 46 images were used to compare the pathologist's neoplasia grades with the predicted groups obtained by fractal methods. Results Significant or highly significant differences between all grades of CIN could be found. The confusion matrix, comparing between pathologist's grading and predicted group by fractal methods showed a match of 87.1%. Multifractal spectra were able to differentiate between normal epithelium and low grade as well as high grade neoplasia. Conclusion Fractal dimension can be considered to be an objective parameter to grade cervical intraepithelial neoplasia. PMID:25302712

    Full Text Available Cervical cancer remains a significant cause of morbidity and mortality for women in developing countries, despite the fact that inexpensive, simple and effective screening methods are available. Visual inspection of the cervix with acetic acid (VIA can be used as part of a “screen and treat” program to identify precancerous lesions for cryotherapy treatment. This case report details how the VIA screening test was incorporated into the care of a patient presenting to a maternal health clinic in Thomonde, Haiti which was staffed by doctors and medical students from Emory University School of Medicine in collaboration with Haiti Medishare. As demonstrated here, the VIA test requires minimal materials, can be efficiently incorporated into a physical exams, provides immediate results, and is easily demonstrated to and performed by local healthcare providers. The straightforward and sensitive VIA technique is an ideal cervical cancer screening method for resource poor areas.

    2013-01-01

    Regarded as infrequent, vaginal and cervical endometriosis is probably more common than is generally realized. The apparent rarity of the lesion may be ascribed to the limited awareness of its clinical appearance, combined with technical difficulty in obtaining suitable biopsy material for confirmation. Thus, clinical recognition and tissue confirmation become essential. This paper focuses on vaginal and cervical endometriosis, documenting the clinical, macroscopic, cytological and colposcopic findings in 4 cases seen at a single physical vaginal examination. Diagnosis in these patients was facilitated and improved by fine needle aspiration cytology and confirmed by histology. This technique, which is not used for the diagnosis of endometriosis, could be an option in low-income areas. PMID:23406608

    DNA-damage tolerance (DDT) is defined as a mechanism by which eukaryotic cells resume DNA synthesis to fill the single-stranded DNA gaps left by replication-blocking lesions. Eukaryotic cells employ two different means of DDT, namely translesion DNA synthesis (TLS) and template switching, both of which are coordinately regulated through sequential ubiquitination of PCNA at the K164 residue. In the budding yeast Saccharomyces cerevisiae, the same PCNA-K164 residue can also be sumoylated, which recruits the Srs2 helicase to prevent undesired homologous recombination (HR). While the mediation of TLS by PCNA monoubiquitination has been extensively characterized, the method by which K63-linked PCNA polyubiquitination leads to template switching remains unclear. We recently identified a yeast heterotetrameric Shu complex that couples error-free DDT to HR as a critical step of template switching. Here we report that the Csm2 subunit of Shu physically interacts with Rad55, an accessory protein involved in HR. Rad55 and Rad57 are Rad51 paralogues and form a heterodimer to promote Rad51-ssDNA filament formation by antagonizing Srs2 activity. Although Rad55-Rad57 and Shu function in the same pathway and both act to inhibit Srs2 activity, Shu appears to be dedicated to error-free DDT while the Rad55-Rad57 complex is also involved in double-strand break repair. This study reveals the detailed steps of error-free lesion bypass and also brings to light an intrinsic interplay between error-free DDT and Srs2-mediated inhibition of HR. PMID:24339919

    Cervical cancer (CC) is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST). Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL) and CC(p = 0.006, p = 0.036).When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006) and the largest distance compared to NCL-HPV negative ones (p<0.00001). The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings. PMID:27115350

    Full Text Available Abstract Background Human papillomavirus (HPV infection is a major risk factor for the development of nearly all cases of cervical cancer worldwide. The presence of HPV DNA in cases of esophageal squamous-cell carcinoma (ESCC has been reported repeatedly from Shantou, China, and other regions with a high incidence of esophageal carcinoma (EC. However, unlike in cervical squamous-cell carcinoma (CSCC, in ESCC, the characteristics of HPV are unclear. Thus, the role of high-risk HPV types in the carcinogenesis of ESCC remains uncertain. Methods Seventy cases of ESCC with 60 controls and 39 cases of CSCC with 54 controls collected from patients in Shantou region in China were compared for the distributions of HPV-16, -18 and -58; viral load; and viral integration using real-time PCR assay and HPV-16 expression using immunostaining. Results The detection rates and viral loads of HR-HPV infection were significantly lower in ESCC than in CSCC (50.0% vs. 79.48%, P = 0.005; 2.55 ± 3.19 vs. 361.29 ± 441.75, P = 0.002, respectively. The combined integration level of HPV-16, -18 and -58 was slightly lower in ESCC than in CSCC (P = 0.022. HPV-16 expression was detected in 59.26% of ESCC tissue and significantly associated with tumour grade (P = 0.027. Conclusions High levels of HR-HPV expression and integration may be an indicator of the risk of ESCC, at least for patients in the Shantou region of China. However, a relatively low HPV copy number and infection rate in ESCC is unlikely to play an essential a role in the carcinogenesis of ESCC as in cervical cancer. Factors other than HR-HPV infection may contribute to the carcinogenesis of ESCC.

To assess the risk of cervical intraepithelial neoplasia grades 2, 3 or higher (CIN 2/3+ for women with normal cytology and concurrent high-risk human papillomavirus infection (HR-HPV. MATERIAL AND METHODS. We examined 2 200 women every 6 months for an average of 9 years. Cervical smears and samples for HPV DNA were obtained at each visit. Absolute risk of subsequent CIN2/CIN3+ was estimated using the Kaplan-Meier method. RESULTS. The absolute risk of CIN2/CIN3+ among HR-HPV-positive women with normal Pap smear results was 1.06% (95%CI, 0.57-2.20, 5 times higher the risk among all women with normal Pap smears (0.20%; 95%CI, 0.12-0.32 but 7 times lower than that for women with HR-HPV infection and LSIL (7.24%; 95%CI, 3.78-15.2. CONCLUSION. Short-term absolute risk of CIN2/3+ after a normal Pap smear with concurrent HR-HPV infection is low (~1%, suggesting that the HR-HPV test has limited utility in short-term clinical decision-making for women with normal cytology.OBJETIVO.

  14. Cervical cancer: Can it be prevented?

    Science.gov (United States)

    Aggarwal, Pakhee

    2014-10-10

    Cervical cancer prevention requires a multipronged approach involving primary, secondary and tertiary prevention. The key element under primary prevention is human papilloma virus (HPV) vaccination. So far, only prophylactic HPV vaccines which prevent HPV infection by one or more subtypes are commercially available. Therapeutic HPV vaccines which aid in clearing established infection are still under trial. Secondary prevention entails early detection of precancerous lesions and its success is determined by the population coverage and the efficacy of the screening technique. A number of techniques are in use, including cytology, visual inspection (using the naked eye, magnivisualizer, acetic acid and Lugol's iodine), HPV testing and a combination of these methods. Updated screening guidelines have been advocated by the American Cancer Society in light of the role of HPV on cervical carcinogenesis. Recent research has also focussed on novel biomarkers that can predict progression to cancer in screen positive women and help to differentiate those who need treatment from those who can be left for follow-up. Last but not the least, effective treatment of precancerous lesions can help to reduce the incidence of invasive cervical cancer and this constitutes tertiary prevention. A combination of these approaches can help to prevent the burden of cervical cancer and its antecedent morbidity and mortality, but all of these are not feasible in all settings due to resource and allocation constraints. Thus, all countries, especially low and middle income ones, have to determine their own cocktail of approaches that work before we can say with certainty that yes, cervical cancer can be prevented.

    Full Text Available   Objective(s: To investigate the expression of human papilloma virus (HPV L1 capsid protein, and human telomerase RNA component (hTERC in cervical cancer and the role of detection of both genes in screening of cervical cancer.   Materials and Methods: A total of 309 patients were recruited and cervical exfoliated cells were collected. Immunocytochemistry was employed to detect HPV L1 capsid protein, and fluorescent in situ hybridization (FISH was performed to detect the hTERC. Results: The expression of HPV L1 capsid protein reduced with the increase of the histological grade of cervical cells and was negatively related to the grade of cervical lesions. However, the expression of hTERC increased with the increase of the histological grade and positively associated with the grade of cervical lesions. The proportion of patients with L1(-/hTERC(+ was higher in patients with histological grade of CIN2 or higher than that in those with histological grade of CIN1. The L1(+/hTERC(- and L1(-/hTERC(- were negatively related to the grade of cervical lesions. L1(-/hTERC(+ was positively associated with the grade of cervical lesions. The L1/hTERC ratio increased. The negative predictive value of both HPV L1 and hTERC was higher than that of HPV L1 or hTERC, but there was no marked difference in the screening efficacy of cervical cancer among HPV L1, hTERC and HPV L1+hTERC. Conclusion: HPV L1 capsid protein and hTERC gene may serve as markers for the early diagnosis and prediction of cervical lesions. The increase in L1/hTERC ratio reflects the progression of cervical lesions to a certain extent.

  17. The diameters of the cervical spinal cord shown by Amipaque-myelography

    International Nuclear Information System (INIS)

    The sagittal and cross diameters of the cervical spinal cord were measured in 53 patients with cervical nerve root compression and with no evidence of spinal cord involvement, as well as in 45 patients with spastic tetraparesis and no localised space occupying lesion, and 29 patients with myelographically proven cervical myelography. The true diameters were calculated by the known magnification factor (1:1,4). Patients with spastic tetraparesis showed diameters in normal ranges, as well as widened or diminished sizes of the cord. Some of the patients with cervical myelopathy showed diminished diameters in the caudal parts. This may be a hint for a poor outcome after decompression operation. (orig.)

    Cervical varix is a rare cause of obstetric hemorrhage which needs accurate diagnosis and prompt management because the lesion may be associated with preterm delivery and maternal complications. Our patient was diagnosed with cervical varix and vaginal bleeding at 32 weeks' gestation, using trans vaginal ultrasound and MRI. Persistent vaginal bleeding and preterm labor led to an emergency cesarean section at 33 weeks' gestation. After delivery, cervical varix was spontaneously resolved in the follow-up trans vaginal ultrasound and CT. We report various radiologic features of cervical varix combined with vaginal bleeding in late pregnancy

    The cervical spine was examined with the magnetic resonance imaging (MRI) and the conventional roentgenograms in 95 patients with rheumatoid arthritis. The MRI findings of upper cervical disorders were compared with various values determined in roentgenograms: the atlanto-dental interval (ADI), the space available for the spinal cord (SAC), and the Ranawat and Redlund-Johnell values. In patients with vertical setting (VS), MRI showed medullary compression in all those with abnormal Redlund-Johnell values and Ranawat values of 7 mm or less. In patients with anterior atlanto-axial subluxation, compression of the upper cervical cord was observed in all patients with SAC of 13 mm or less. In subaxial lesion of the cervical spine, MRI was found to be as good as roentgenograms in evaluating plate erosion and disc space narrowing and MRI showed extradural pannus. (author).

    The authors analyzed cervical intraepithelial neoplasias (CINs) detected after cryotherapy to determine if recurrence is associated with the same human papillomavirus (HPV) type found in the original lesion. Eight women had detectable HPV DNA in CINs that occurred after ablation of another CIN, and for each patient the HPV type in the pretreatment lesion was different from that in the CIN that appeared after cryotherapy. This compares with 12 women who had HPV detected in two or more CINs present at the same time, 11 of whom had the same HPv type noted. they concluded that although multiple, simultaneous CINs in a woman often contain the same HPV type, recurrent CINs that occur after cryotherapy contain an HPV type different from that present in the pretreatment lesion.

    Maternidade Santa Brígida de Curitiba, PR, were selected. Those patients were sent to colposcopy under the following criteria: 1 previous abnormal cytopathological exams, 2 Indicative clinical data or, 3 Suspected lesions on gynecological exam. The statistical significance analysis of the results was done using the chi-square test. Sensibility, specificity, positive predictive value (PPV and negative predictive value (NPV were also determined.RESULTS: The patients' mean age was 30.2 (±10.9. Cytopathological capability of identifying lesions was 50% when compared to histology. Its specificity was 77%, the sensibility 41%, the PPV 74%, and the NPV 45%. Colposcopy capability of identifying lesions was 50%. Its sensibility, specificity, PPV and NPV were 96%, 19%, 65% and 75% respectively. The two methods associated were capable of identifying 63% of the lesions.CONCLUSIONS: Cytopathology was a high specificity exam, while colposcopy from those selected patients had a high sensibility. Colposcopy association with cytopathological screening, on those selected patients, significantly raises the diagnostic accuracy of cervical cancer precursor lesions.

  18. CT rim effects in various head and neck lesions

    International Nuclear Information System (INIS)

    The authors evaluated various head and neck lesions seen from April 1988 through March 1990 both by plain and enhanced CT, examined the incidence of rim effect (or rim enhancement), classified these effects, and discussed underlying mechanisms. The subjects were 177 patients with primary tumors (28 benign and 49 malignant tumors), lymphadenopathy associated with malignancy (9), inflammatory lesions (20), cystic lesions (12), other lesions (7), and 22 without abnormal findings. Among these 177, rim effects were observed in 22 cases (12%). These effects were analyzed and classified. The incidences of rim effect according lesion type are as follows; cervical lymphadenopathy associated with malignancy 5/9 (56%), primary tumors 8/77 (10%), inflammatory lesions none, cystic lesions 7/12 (58%), and others 3/7 (43%). The highest incidence was seen with cystic lesions including mucoceles of the paranasal sinuses and cervical cysts. Rim effects were classified as follows; Type 1: cystic pattern, Type 2: parenchymatous pattern, Type 3: vascular pattern and Type 4: others. Type 1 was seen in 15 cases (68%), Type 2 in 3 cases (14%), Type 3 in 3 cases (14%), and Type 4 in 1 case (5%). Type 1 included 6 cystic lesions, 3 malignant lymphadenopathies, 3 benign tumors and others. Type 2 included 2 malignant lymphadenopathies and 1 benign tumor, and Type 3, 2 jugular thromboses and 1 carotid atheroma. There was only one Type 4, a cystic lesion. Of interest is the mode of incidences among cervical lymphadenopathies associated with malignancy. Accessory chains showed rim effects in 3/7, all Type 1, and jugular chains in 2/13, all Type 2. The mechanism underlying the rim effects was discussed and the vascularity of the peripheral rims of the lesions appeared to be the most important factor in addition to technical artifacts inherent in CT.

    Background: Cervical cancer is the fourth most common cancer among women worldwide. Organized cervical screening and vaccination against human papilloma virus (HPV) have been successful interventions for prevention of invasive cervical cancer (ICC). Because of cultural and religious considerations, ICC has low incidence in Iran and many other Muslim countries. There is no organized cervical screening in these countries. Therefore, ICC is usually diagnosed in advanced stages with poor prognosis in these countries. We performed a priority setting exercise and suggested priorities for prevention of ICC in this setting. Methods: We invited experts and researchers to a workshop and asked them to list important suggestions for ICC prevention in Iran. After merging similar items and removing the duplicates, we asked the experts to rank the list of suggested items. We used a strategy grid and Go-zone analysis to determine final list of priorities for ICC prevention in Iran. Results: From 26 final items suggested as priorities for prevention of ICC, the most important priorities were developing national guidelines for cervical screening and quality control protocol for patient follow-up and management of precancerous lesions. In addition, we emphasized considering insurance coverage for cervical screening, public awareness, and research priorities, and establishment of a cervical screening registry. Conclusion: A comprehensive approach and implementation of organized cervical screening program is necessary for prevention of ICC in Iran and other low incidence Muslim countries. Because of high cost for vaccination and low incidence of cervical cancer, we do not recommend HPV vaccination for the time being in Iran.

    Cervical cancer is the second most common cause of death from cancer in women worldwide, and the development of new diagnostic, prognostic, and treatment strategies merits special attention. Many efforts have been made to design new drugs and develop immunotherapy and gene therapy strategies to treat cervical cancer. HPV genotyping has potentially valuable applications in triage of low-grade abnormal cervical cytology, assessment of prognosis and followup of cervical intraepithelial neoplasia, and in treatment strategies for invasive cervical cancer. It is known that during the development of cervical cancer associated with HPV infection, a cascade of abnormal events is induced, including disruption of cellular cycle control, alteration of gene expression, and deregulation of microRNA expression. Thus, the identification and subsequent functional evaluation of host proteins associated with HPV E6 and E7 oncoproteins may provide useful information in understanding cervical carcinogenesis, identifying cervical cancer molecular markers, and developing specific targeting strategies against tumor cells. Therefore, in this paper, we discuss the main diagnostic methods, management strategies, and followup of HPV-associated cervical lesions and review clinical trials applying gene therapy strategies against the development of cervical cancer.

    Teratoma of the head and neck is a rare lesion comprising 6 % of all teratomas, with only 3 % occurring in the cervical region [1]. Most are non-malignant lesions consisting of a variety of tissues of variable maturity, commonly with neuroepithelial and thyroid elements. They often present as a large cystic mass in the neck of a neonate or infant and frequently cause respiratory embarrassment due to local mass effect necessitating urgent surgical intervention. They may be difficult to distinguish from cystic hygromas, both clinically and radiologically. Imaging plays an important role in the assessment of these lesions, especially in preparation for surgery. We present a case of cervical teratoma and emphasise the role of MRI. (orig.)

    2015-01-01

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    2007-01-01

    Full Text Available Cervical cancer has been recognized as a rare outcome of a common Sexually Transmitted Infection (STI. The etiologic association is restricted to a limited number of viral types of the family of the Human Papillomaviruses (HPVs. The association is causal in nature and under optimal testing systems, HPV DNA can be identified in all specimens of invasive cervical cancer. As a consequence, it has been claimed that HPV infection is a necessary cause of cervical cancer. The evidence is consistent worldwide and implies both the Squamous Cell Carcinomas (SCC, the adenocarcinomas and the vast majority (i.e. > 95% of the immediate precursors, namely High Grade Squamous Intraepithelial Lesions (HSIL/Cervical Intraepithelial Neoplasia 3 (CIN3/Carcinoma in situ. Co-factors that modify the risk among HPV DNA positive women include the use of oral contraceptives (OC for five or more years, smoking, high parity (five or more full term pregnancies and previous exposure to other sexually transmitted diseases such as Chlamydia Trachomatis (CT and Herpes Simplex Virus type 2 (HSV-2. Women exposed to the Human Immunodeficiency Virus (HIV are at high risk for HPV infection, HPV DNA persistency and progression of HPV lesions to cervical cancer.

    When symptoms bring to light a cervical spine degenerative disc process that requires surgical intervention, a symptom relieving procedure such as decompression, followed by functional restoration, arthroplasty, offers the benefit of prophylaxis of accelerated spondylosis at the operated level. In addition, by altering the biomechanical stress factors at adjacent levels, theoretically it should offer prophylactic benefit at these levels as well. The design requirements for a cervical disc pro...

  17. Cyclin A1 promoter hypermethylation in human papillomavirus-associated cervical cancer

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate epigenetic status of cyclin A1 in human papillomavirus-associated cervical cancer. Y. Tokumaru et al., Cancer Res 64, 5982-7 (Sep 1, 2004)demonstrated in head and neck squamous-cell cancer an inverse correlation between cyclin A1 promoter hypermethylation and TP53 mutation. Human papillomavirus-associated cervical cancer, however, is deprived of TP53 function by a different mechanism. Therefore, it was of interest to investigate the epigenetic alterations during multistep cervical cancer development. In this study, we performed duplex methylation-specific PCR and reverse transcriptase PCR on several cervical cancer cell lines and microdissected cervical cancers. Furthermore, the incidence of cyclin A1 methylation was studied in 43 samples of white blood cells, 25 normal cervices, and 24, 5 and 30 human papillomavirus-associated premalignant, microinvasive and invasive cervical lesions, respectively. We demonstrated cyclin A1 methylation to be commonly found in cervical cancer, both in vitro and in vivo, with its physiological role being to decrease gene expression. More important, this study demonstrated that not only is cyclin A1 promoter hypermethylation strikingly common in cervical cancer, but is also specific to the invasive phenotype in comparison with other histopathological stages during multistep carcinogenesis. None of the normal cells and low-grade squamous intraepithelial lesions exhibited methylation. In contrast, 36.6%, 60% and 93.3% of high-grade squamous intraepithelial lesions, microinvasive and invasive cancers, respectively, showed methylation. This methylation study indicated that cyclin A1 is a potential tumor marker for early diagnosis of invasive cervical cancer

  18. MicroRNA expression variability in human cervical tissues.

    Directory of Open Access Journals (Sweden)

    Patrícia M Pereira

    Full Text Available MicroRNAs (miRNAs are short (approximately 22 nt non-coding regulatory RNAs that control gene expression at the post-transcriptional level. Deregulation of miRNA expression has been discovered in a wide variety of tumours and it is now clear that they contribute to cancer development and progression. Cervical cancer is one of the most common cancers in women worldwide and there is a strong need for a non-invasive, fast and efficient method to diagnose the disease. We investigated miRNA expression profiles in cervical cancer using a microarray platform containing probes for mature miRNAs. We have evaluated miRNA expression profiles of a heterogeneous set of cervical tissues from 25 different patients. This set included 19 normal cervical tissues, 4 squamous cell carcinoma, 5 high-grade squamous intraepithelial lesion (HSIL and 9 low-grade squamous intraepithelial lesion (LSIL samples. We observed high variability in miRNA expression especially among normal cervical samples, which prevented us from obtaining a unique miRNA expression signature for this tumour type. However, deregulated miRNAs were identified in malignant and pre-malignant cervical tissues after tackling the high expression variability observed. We were also able to identify putative target genes of relevant candidate miRNAs. Our results show that miRNA expression shows natural variability among human samples, which complicates miRNA data profiling analysis. However, such expression noise can be filtered and does not prevent the identification of deregulated miRNAs that play a role in the malignant transformation of cervical squamous cells. Deregulated miRNAs highlight new candidate gene targets allowing for a better understanding of the molecular mechanism underlying the development of this tumour type.

  19. MRI of anterior spinal artery syndrome of the cervical spinal cord

    International Nuclear Information System (INIS)

    Cervical spinal cord lesions in the anterior spinal artery syndrome were delineated on magnetic resonance images (MRI) in four patients. The lesion was always seen anteriorly in the cervical cord. On T2-weighted images, the lesions appeared hyperintense relative to the normal spinal cord, while on T1-weighted images, two chronic lesions appeared hypointense, with local atrophy of the cord. In one case, repeated T1-weighted images showed no signal abnormality 4 days after the ictus, but the lesion became hypointense 18 days later, when contrast enhancement was also recognized after injection of Gd-DTPA; this sequence of intensity changes was similar to that of cerebral infarction. The extent of the lesion seen MRI correlated closely with neurological findings in all cases. Although the findings may not be specific, MRI is now the modality of choice for confirming the diagnosis in patients suspected of having an anterior spinal artery syndrome. (orig.)

    Full Text Available Nerve tumors arising from the sympathetic chain are uncommon slow-growing tumors and represent a diagnosis challenge. Their malignant degeneration is rare. Definitive pre-operative diagnosis may be difficult as investigations are not usually helpful. We report the case of a 23-year old woman who presented with an asymptomatic solitary left cervical swelling. She was evaluated with sonography and computed tomography. Complete surgical excision of the lesion was carried out and histologic examination revealed a schwannoma. Post-operatively, the patient showed clinical findings of Horner’s syndrome. Pathologic and radiological evaluation, differential diagnosis of this neoplasm and its management are discussed.

  1. Cervical cancer screening in Belgium and overscreening of adolescents.

    2016-03-01

    There has been a marked decrease in the incidence of cervical cancer thanks to cytological screening with the Pap smear test. In Belgium, this screening is rather opportunistic. Over 39% of Belgian women between 25 and 64 years of age are never or only rarely screened by cytological tests. Moreover, there is an excess use of Pap smears because of women who rely on their yearly cervical smear and because many Pap smears are obtained from women beyond the target age range of 25 to 64 years. Sexually active adolescents are increasingly being recognized as a population distinct from adult women. They are at a high risk of acquiring the human papillomavirus (HPV), but most infections and cervical intraepithelial lesions caused by HPV are efficiently cleared by the immune system. We present a description of cervical cancer screening in Belgium using the database of the National Health Insurance Institute (RIZIV/INAMI) and the Belgian Health Care Knowledge Centre (KCE). We describe why elimination of Pap testing in the adolescent population reduces costs and harms without increasing cervical cancer rates. Expectant management, education on the risk factors for cervical cancer and HPV persistence, and HPV vaccination are very important in adolescents and young adults. PMID:25812038

    Full Text Available Schwannomas (neurilemmomas are benign tumors arising from the Schwann cells of the neural sheath. They are typically, well-encapsulated lesions which rarely adhere to the adjacent structures. In the chest, schwannomas are often seen within the posterior mediastinum and commonly originating along intercostal nerves. Several operative approaches have previously been described for the resection of these tumors, including thoracoscopic techniques and posterolateral thoracotomy. We report in this case a giant cystic mediastinal schwannoma of the left recurrent laryngeal nerve with cervical extension, unresectable by the usual described approaches, which was completely removed through a cervical approach.

    Full Text Available We report a rare patient of a simultaneous extradural and intradural compression of the cervical spinal cord due to co-existent intervertebral disc herniation and an intradural schwannoma at the same level. The intradural lesion was missed resulting in recurrence of myelopathy after a surprisingly complete functional recovery following anterior cervical discectomy. Retrospectively, it was noted that the initial cord swelling noticed was tumor being masked by the compression produced by the herniated disc. A contrast magnetic resonance imaging scan is important in differentiating intradural tumors of the spinal cord. A high index of suspicion is often successful in unmasking both the pathologies.

    Background:Occult invasive cervical cancer discovered after simple hysterectomy is not common, radical parame‑trectomy (RP) is a preferred option for young women. However, the morbidity of RP was high. The aim of our study is to assess the incidence of parametrial involvement in patients who underwent radical parametrectomy for occult cervical cancer or radical hysterectomy for early‑stage cervical cancer and to suggest an algorithm for the triage of patients with occult cervical cancer to avoid RP. Methods:A total of 13 patients with occult cervical cancer who had undergone RP with an upper vaginectomy and pelvic lymphadenectomy were included in this retrospective study. Data on the clinicopathologic characteristics of the cases were collected. The published literature was also reviewed, and low risk factors for parametrial involvement in early‑stage cervical cancer were analyzed. Results:Of the 13 patients, 9 had a stage IB1 lesion, and 4 had a stage IA2 lesion. There were four patients with grade 1 disease, seven with grade 2 disease, and two with grade 3 disease. The median age of the entire patients was 41years. The most common indication for extrafascial hysterectomy was cervical intraepithelial neoplasia 3. Three patients had visible lesions measuring 10–30mm, in diameter and ten patients had cervical stromal invasions with depths ranging from 4 to 9mm; only one patient had more than 50% stromal invasion, and four patients had lymph‑vascular space invasion (LVSI). Perioperative complications included intraoperative bowel injury, blood transfusion, vesico‑vaginal ifstula, and ileus (1 case for each). Postoperative pathologic examination results did not show residual disease or parametrial involvement. One patient with positive lymph nodes received concurrent radiation therapy. Only one patient experienced recurrence. Conclusions:Perioperative complications following RP were common, whereas the incidence of parametrial involve‑ment was very low

    Objective: To investigate and analyze the incidences of non-carious cervical lesions and occlusal wear in the middle-aged and elderly, their correlations, and the possible risk factors associated with the formation of each. Method: A total of 568 office staff aged 45 years and above were involved. All the patients were examined for the presence and severity of NCCL and occlusal wear using the Tooth Wear Index (TWI). Result: The prevalence rates of NCCL and occlusal wear were observed 73.24 % and 87.50 % respectively in this population. Both the occurrence rates and tooth wear degrees were significantly related to the gender and the age. The prevalence of teeth with NCCL was significantly higher when the occlusal wear presented, and teeth with occlusal wear were more frequently observed the presence of NCCL (P <0.05). This study did not find significant associations between these two lesions and bruxism, dietary habits, and toothbrushing methods. Conclusion: NCCL and occlusal wear were common phenomena in the middle-aged and elderly. A relationship between the the incidences of each lesion was found. Occlusal force, mechanical friction and age were the common risk factors for NCCL and occlusal wear, but aggravating factors were different.%目的:调查中老年人群牙颈部非龋性缺损(NCCL)与(牙合)面磨损发生情况,并对两者的发病因素和相互关系进行探讨.方法:对568名45岁及以上机关干部,使用Smith和Knight牙齿磨损指数(TWI)进行牙颈部非龋性缺损与(牙合)面磨损的患病情况调查.结果:该研究人群NCCL的患病率为73.24%,(牙合)面磨损患病率为87.50%.NCCL和(牙合)面磨损的患病率和严重程度与性别和年龄相关,发生(牙合)面磨损的患牙更易发生NCCL,反之亦然(P<0.05).该人群的磨牙症史、饮食习惯及刷牙方法与NCCL和(牙合)面磨损的发生没有明显相关性.结论:牙颈部非龋性缺损与(牙合)面磨损在中老年人中较

  8. Genotype distribution of human papillomavirus (HPV) in histological sections of cervical intraepithelial neoplasia and invasive cervical carcinoma in Madrid, Spain

    International Nuclear Information System (INIS)

    Human Papillomavirus (HPV) genotype distribution and co-infection occurrence was studied in cervical specimens from the city of Madrid (Spain), as a contribution to the knowledge of Human Papillomavirus genotype distribution and prevalence of carcinogenic HPV types in cervical lesions in Spain. A total of 533 abnormal specimens, from the Hospital General Universitario “Gregorio Marañón” of Madrid, were studied. These included 19 benign lesions, 349 cervical intraepithelial neoplasias 1 (CIN1), 158 CIN2-3 and 7 invasive cervical carcinomas (ICC). HPV genotyping was performed using PCR and tube array hybridization. We detected 20 different HPV types: 13 carcinogenic high-risk HPV types (HR-HPVs), 2 probably carcinogenic high-risk HPV types (PHR-HPVs) and 5 carcinogenic low-risk HPV types (LR-HPVs). The most frequent HPV genotypes found in all specimens were HPV16 (26.0%), 31 (10.7%) and 58 (8.0%). HPV 18 was only detected in 5.0%. Co-infections were found in 30.7% of CIN 1 and 18.4% cases of CIN2-3. The highest percentage of HR HPVs was found in those specimens with a CIN2-3 lesion (93.7%). As our study shows the current tetravalent vaccine could be effective in our geographical area for preventing all the invasive cervical carcinomas. In addition, upon the estimates of the important presence of other HR-HPV types – such as 31, 58, 33 and 52 – in different preneoplasic lesions the effectiveness of HPV vaccination in our geographical area, and others with similar genotype distribution, should be limited

    Telomerase activity was examined in invasive cervical carcinoma to assess whether it is activated during cervical malignant transformation and to look for its possible association with human papillomavirus (HPV) infection. Histologically confirmed invasive cervical carcinomas and benign cervices were assayed for telomerase activity by using a modified telomere repeat amplification protocol (TRAP). The same cases were subjected to polymerase chain reaction (PCR) detection of HPV by using consensus primers and type-specific (HPV types 16 and 18) primers. Telomerase activity was detected in 40 of 45 (88.9%) invasive cervical carcinomas and 2 (all chronic cervicitis) of 50 (4%) benign cervical lesions. HPV was detected in 36 (24 HPV-16 and 4 HPV-18 cases) of 45 (80%) invasive cervical carcinomas and 20 (11 HPV-16 and 1 HPV-18 cases) of 50 (40%) benign cervical changes. There was a significant correlation between the expression of telomerase with histological grade (φ=0.44, P<0.005), but no correlation was found between telomerase expression and HPV-18 (P>0.05). Although larger sample studies are needed, there seems to be a clear association between telomerase upregulation and HPV status, mainly HPV-16 infection.

    The chemokine CXCL12 is highly expressed in gynecologic tumors and is widely known to play a biologically relevant role in tumor growth and spread.Recent evidence suggests that CXCL16,a novel chemokine,is overexpressed in inflammation-associated tumors and mediates pro-tumorigenic effects of inflammation in prostate cancer.We therefore analyzed the expression of CXCL12 and CXCL16 and their respective receptors CXCR4 and CXCR6 in cervical intraepithelial neoplasia (CIN) and cervical cancer and further assessed their association with clinicopathologic features and outcomes.Tissue chip technology and immunohistochemistry were used to analyze the expression of CXCL12,CXCR4,CXCL16,and CXCR6 in healthy cervical tissue (21 cases),CIN (65 cases),and cervical carcinoma (60 cases).The association of protein expression with clinicopathologic features and overall survival was analyzed.These four proteins were clearly detected in membrane and cytoplasm of neoplastic epithelial cells,and their distribution and intensity of expression increased as neoplastic lesions progressed through CIN1,CIN2,and CIN3 to invasive cancer.Furthermore,the expression of CXCR4 was associated significantly with the histologic grade of cervical carcinoma,whereas the expression of CXCR6 was associated significantly with lymph node metastasis.In Kaplan-Meier analysis,patients with high CXCR6 expression had significantly shorter overall survival than did those with low CXCR6 expression.The elevated co-expression levels of CXCL12/CXCR4 and CXCL16/CXCR6 in CIN and cervical carcinoma suggest a durative process in cervical carcinoma development.Moreover,CXCR6 may be useful as a biomarker and a valuable prognostic factor for cervical cancer.

    1992-01-01

    Three patients developed signs of a unilateral cervical cord lesion 6 to 36 h after the acute onset of severe cervico-brachial pain. The neurological deficit progressed over 6 to 18 h. On the painful side a central Horner's syndrome, a hemiparesis with plegia of the hand, and a slight pallhypaesthesia were found. On the opposite side thermhypaesthesia and hypalgesia were noted with a level at the dermatome C5 or C6. T2-weighted MR images revealed in one patient a small area of increased signal intensity restricted to one half of the cervical cord, and electromyography in another patient showed after 6 months evidence of segmental chronic denervation. Both abnormalities were found at the clinically expected level. The findings are consistent with a small infarction of the cervical cord in the perfusion territory of a central (sulco-commissural) artery, a duplicated anterior spinal artery or an anterior spinal branch of the vertebral artery.

    Uterine Cervical Cancer is one of the most common forms of cancer in women worldwide. Most cases of cervical cancer can be prevented through screening programs aimed at detecting precancerous lesions. During Digital Colposcopy, colposcopic images or cervigrams are acquired in raw form. They contain specular reflections which appear as bright spots heavily saturated with white light and occur due to the presence of moisture on the uneven cervix surface and. The cervix region occupies about half of the raw cervigram image. Other parts of the image contain irrelevant information, such as equipment, frames, text and non-cervix tissues. This irrelevant information can confuse automatic identification of the tissues within the cervix. Therefore we focus on the cervical borders, so that we have a geometric boundary on the relevant image area. Our novel technique eliminates the SR, identifies the region of interest and makes the cervigram ready for segmentation algorithms.

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

    Conclusions: MN scoring on the epithelial cells of cervix could be used as a biomarker in cancer screening. This is an easy, simple, reliable, reproducible and objective test which can be performed on routinely stained pap smears.

  6. Rheumatoid cervical myelopathy

    International Nuclear Information System (INIS)

    Rheumatoid cervical myelopathy was studied in 14 patients, clinically, radiographically and by computerized tomography with multiplanar reconstruction (CT/MPR). CT/MPR demonstrated significant unsuspected areas of compromise in 9 of the 14 patients, and altered the surgical procedure in 7 of these 9 patients. CT/MPR clearly identifies all levels of involvement including rotary subluxation. CT/MPR also allows assessment of the spinal nerve canal/foramen and the alignment of the foramina transversaria. CT/MPR is an essential addition to the evaluation of rheumatoid cervical myelopathy

    Full Text Available Cervical necrotizing fasciitis is an unusual encounter in the general surgical practice, but is a life-threatening condition requiring early recognition and adequate surgical treatment. We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

    Acute cervical sprain traumas can be divided into simple and severe, depending on the presence of organic lesions which can be documented by conventional radiologic techniques. Persistent painful symptomatology of the nape and the precise localization of pain, led us to suspect the presence of organic lesions due to tearing of the neck muscles in 94 patients who had suffered a simple cervical sprain. To demonstrate these post-traumatic lesions, the patients were subjected to US examinations of both the nape and the muscles at the base of the neck. In 13 cases (13.8%) muscular tearing lesions were demonstrated, which were characterized by hypoechoic lacunae (6 cases), by hyperechoic stripes (5 cases), and by muscular hernia (1 case); in 1 case, partial disconnection of a muscular insertion was demonstrated. Thus, we believe muscle-tendon US to be a valuable technique for both diagnostic and nosologic purposes, for the method allows simple cervical sprain to be discriminated from sprains which are complicated by organic muscular lesions. We suggest that the cervical sprain traumas where a muscular lesion due to tearing can be demonstrated be defined as "complex" traumas. PMID:1579667

    Cancer is a complex disease caused by genetic and epigenetic abnormalities that affect gene expression. The progression from precursor lesions to invasive cervical cancer is influenced by persistent human papilloma virus (HPV) infection, which induces changes in the host genome and epigenome. Epigenetic alterations, such as aberrant miRNA expression and changes in DNA methylation status, favor the expression of oncogenes and the silencing of tumor-suppressor genes. Given that some miRNA genes can be regulated through epigenetic mechanisms, it has been proposed that alterations in the methylation status of miRNA promoters could be the driving mechanism behind their aberrant expression in cervical cancer. For these reasons, we assessed the relationship among HPV infection, cellular DNA methylation and miRNA expression. We conclude that alterations in the methylation status of protein-coding genes and various miRNA genes are influenced by HPV infection, the viral genotype, the physical state of the viral DNA, and viral oncogenic risk. Furthermore, HPV induces deregulation of miRNA expression, particularly at loci near fragile sites. This deregulation occurs through the E6 and E7 proteins, which target miRNA transcription factors such as p53. PMID:24737381

    Full Text Available Abstract A ten-year-old male standard dachshund was presented with a history of neck pain and progressive gait disturbances. Following a neurological examination and diagnostic imaging, including CT, a neoplastic lesion involving the third and fourth cervical vertebrae was suspected. The lesion included an extradural mass on the right side of the spinal canal causing a local compression of the cervical cord. Surgery, using a modified dorsal laminectomy procedure, was performed in order to decompress the cervical spinal cord. Histopathological examination of the extradural mass indicated that the tumour was a chondroid chordoma. Following discharge, the quality of life for the dog was very good for a sustained period, but clinical signs recurred at 22 months. The dog was euthanased 25 months post-surgery. On post-mortem examination, a regrowth of neoplastic tissue was found to have infiltrated the bone and spinal cord at C3-C4. This is the first report to show that palliative surgery can offer successful long-lasting treatment of chondroid chordoma of the cervical spine in the dog.

    Full Text Available A carcinogênese é um processo de múltiplas etapas. Alterações no equilíbrio citogenético ocorrem na transformação do epitélio normal a câncer cervical. Numerosos estudos apoiam a hipótese de que a infecção por HPV está associada com o desenvolvimento de alterações malignas e pré-malignas do trato genital inferior. Neste trabalho são apresentadas as bases para a compreensão da oncogênese cervical. O ciclo celular é controlado por proto-oncogenes e genes supressores. Quando ocorrem mutações, proto-oncogenes tornam-se oncogenes, que são carcinogênicos e causam multiplicação celular excessiva. A perda da ação de genes supressores funcionais pode levar a célula ao crescimento inadequado. O ciclo celular também pode ser alterado pela ação de vírus, entre eles o HPV (Human Papiloma Virus, de especial interesse na oncogênese cervical. Os tipos de HPV 16 e 18 são os de maior interesse, freqüentemente associados a câncer cervical e anal. O conhecimento das bases moleculares que estão envolvidas na oncogênese cervical tem sido possível devido a utilização de técnicas avançadas de biologia molecular. A associação destas técnicas aos métodos diagnósticos clássicos, poderão levar a uma melhor avaliação das neoplasias cervicais e auxiliar no desenvolvimento de novas terapias, talvez menos invasivas e mais efetivas.Carcinogenesis involves several steps. Disorders of the cytogenetic balance occur during the evolution from normal epithelium to cervical cancer. Several studies support the hypothesis that the Human Papiloma Virus (HPV infection is associated to development of premalignant and malignant lesions of cervical cancer. In this review we show the basis to understand cervical oncogenesis. The cell cycle is controlled by protooncogenes and supressive genes. This orchestrated cell cycle can be affected by virus such as HPV. Of special interest in the cervical carcinogenesis are the HPV subtypes 16 and 18

    Full Text Available In relation to mechanisms involved in functional recovery of manual dexterity from cervical cord injury or from motor cortical injury, our goal was to determine whether the movements that characterize post-lesion functional recovery are comparable to original movement patterns or do monkeys adopt distinct strategies to compensate the deficits depending on the type of lesion? To this aim, data derived from earlier studies, using a skilled finger task (the modified Brinkman board from which pellets are retrieved from vertical or horizontal slots, in spinal cord and motor cortex injured monkeys were analyzed and compared. Twelve adult macaque monkeys were subjected to a hemi-section of the cervical cord (n=6 or to a unilateral excitotoxic lesion of the hand representation in the primary motor cortex (n=6. In addition, in each subgroup, one half of monkeys (n=3 were treated for 30 days with a function blocking antibody against the neurite growth inhibitory protein Nogo-A, while the other half (n=3 represented control animals. The motor deficits, and the extent and time course of functional recovery were assessed.For some of the parameters investigated (wrist angle for horizontal slots and movement types distribution for vertical slots after cervical injury; movement types distribution for horizontal slots after motor cortex lesion, post-lesion restoration of the original movement patterns (true recovery led to a quantitatively better functional recovery. In the motor cortex lesion groups, pharmacological reversible inactivation experiments showed that the peri-lesion territory of the primary motor cortex or re-arranged, spared domain of the lesion zone, played a major role in the functional recovery, together with the ipsilesional intact premotor cortex.

    Full Text Available BACKGROUND: Minichromosome maintenance proteins (MCM are highly expressed in actively replicating cells. The need for biological markers for cervical carcinoma and its precursor lesions is emerging. Our main aim was to determine the immunohistochemical expression of MCM-2 in HIV-positive and -negative dysplastic cervical specimens. METHODS: Immunohistochemical analysis of MCM-2 was performed in a total of 352 cervical TMA specimens of normal control, low-grade CIN, high-grade CIN and invasive tumor. 38 specimens were from HIV-positive women. A receiver operating characteristic (ROC curve was constructed to determine the best cutoff to diagnose high-grade CIN and invasive cervical cancer. RESULTS: In the progression from normal epithelium to high-grade CIN and invasive tumor we found significant differences in the MCM-2 expression (p<0.05. Based on the ROC curve of 80% with an area under the curve (AUC of 0.78, expression of MCM-2 to diagnose high-grade CIN and invasive tumor resulted in sensitivity of 81%, specificity of 66%, a positive predictive value (PPV of 86% and a negative predictive value (NPV of 57%. HIV-positive cervices revealed a decreasing expression of MCM-2 in both LGCIN and HGCIN compared with HIV-negative specimens (p<0.0001. CONCLUSIONS: The present study suggests that immunohistochemical MCM-2 may not be a promising biomarker for diagnosing high-grade CIN and invasive cancer.

    E2 protein binding to the four E2 binding sites (E2BSs) at the long control region of Human Papillomavirus (HPV) 16/18 genome may exert either transcriptional activation/repression on E6 and E7 oncoproteins. Methylation status at the E2BSs may affect the relative binding of E2 protein to them. In this study, methylation percentage at E2BS 1, 2 (promoter-proximal), and 4 (promoter-distal) were assessed by pyrosequencing and compared among HPV 16/18-positive cervical cancer, high-grade, and low-grade Cervical Intraepithelial Neoplasia, Atypical Squamous Cells of Undetermined Significance, and normal cervical epithelium. HPV 16 E2BS1&2 were more methylated than HPV 16 E2BS4 in cervical cancer whereas in cervical premalignant lesions and normal epithelium, HPV 16 E2BS1&2 were less methylated than HPV 16 E2BS4. HPV 18 E2BS1&2 remained more methylated than E2BS4 in all histological groups. HPV 16 E2BS1&2 methylation increased from high-grade lesions to cervical cancer (P E2 protein to E2BS4. Increasing methylation at HPV 16/18 E2BSs are potentially useful adjunctive molecular markers for predicting progression from low-grade to high-grade cervical premalignant lesions and from high-grade lesions to cervical cancer.

    There have been three physics meetings since the last CMS week: “physics days” on March 27-29, the Physics/ Trigger week on April 23-27 and the most recent physics days on May 22-24. The main purpose of the March physics days was to finalize the list of “2007 analyses”, i.e. the few topics that the physics groups will concentrate on for the rest of this calendar year. The idea is to carry out a full physics exercise, with CMSSW, for select physics channels which test key features of the physics objects, or represent potential “day 1” physics topics that need to be addressed in advance. The list of these analyses was indeed completed and presented in the plenary meetings. As always, a significant amount of time was also spent in reviewing the status of the physics objects (reconstruction) as well as their usage in the High-Level Trigger (HLT). The major event of the past three months was the first “Physics/Trigger week” in Apri...

    Cervical cancer is the second most common female malignancy in Malaysia. Despite advances in treatment, the overall survival for this disease has not changed in the last decade. Infection by certain types of HPV is recognized as a causal and necessary factor for its development. This study was carried out to determine the prevalence of HPV infection in abnormal cervical smears in Malaysian patients using archival cervical smears retrieved from the Cytopathology Unit, Universiti Kebangsaan Malaysia Medical Centre (UKMMC) between the years 1992-1995. DNA was extracted from 38 abnormal smears comprising 25 intraepithelial lesions and 13 cervical carcinomas and 10 normal smears. Amplification of HPV genes was carried out using the polymerase chain reaction (PCR) technique. HPV genotypes were determined using direct sequencing and the results were compared to the database from Genebank. DNA was successfully extracted from all 48 cervical smears. High-risk HPV (HR-HPV) genotypes were detected in 95% of the abnormal smears. Eight high-risk oncogenic types were identified: 16, 18, 31, 51, 52, 56, 58 and 66. All (100%) cervical cancer smears showed presence of HR-HPV compared to 92% of the cervical intraepithelial lesions. Among the eight HR-HPV genotypes identified, HPV 16 and 52 were the commonest (23.7% each) HPV genotypes encountered and among the CIN lesions, HPV 16 (28%) was the most frequent. We conclude that HPV 16 is the most prevalent HPV genotype present in abnormal cervical smears in Malaysian patients, and that the use of archival material to assess the presence of HPV is potentially worthwhile, and can be utilized for longitudinal studies of HPV presence and persistence.

    Full Text Available Confocal light absorption and scattering spectroscopic (CLASS microscopy can detect changes in biochemicals and the morphology of cells. It is therefore used to detect high-grade cervical squamous intraepithelial lesion (HSIL cells in the diagnosis of premalignant cervical lesions. Forty cervical samples from women with abnormal Pap smear test results were collected, and twenty cases were diagnosed as HSIL; the rest were normal or low-grade cervical squamous intraepithelial lesion (LSIL. The enlarged and condensed nuclei of HSIL cells as viewed under CLASS microscopy were much brighter and bigger than those of non-HSIL cells. Cytological elastic scattered light data was then collected at wavelengths between 400 and 1000 nm. Between 600 nm to 800 nm, the relative elastic scattered light intensity of HSIL cells was higher than that of the non-HSIL. Relative intensity peaks occurred at 700 nm and 800 nm. CLASS sensitivity and specificity results for HSIL and non-HSIL compared to cytology diagnoses were 80% and 90%, respectively. This study demonstrated that CLASS microscopy could effectively detect cervical precancerous lesions. Further study will verify this conclusion before the method is used in clinic for early detection of cervical cancer.

    The aim of the present study was to identify novel methylation markers for cervical cancer screening and to test the clinical application of the most promising biomarker in cervical scrapings. Methylated-CpG island recovery assay-based microarray analysis was carried out on a discovery set consisting of cervical cancer tissue and normal cervical tissue to identify significantly hypermethylated genes. Five hundred and four CpG islands, corresponding to 378 genes, were differentially methylated between cervical cancer tissue and normal cervical tissue. Among them, 30 genes were significantly hypermethylated. Of the 30 genes, SOX9, PKLR and DLX4 were selected for further validation by direct bisulfite sequencing. The SOX9 gene revealed complete methylation in the cervical cancer tissue and complete non-methylation in the normal control tissue. A TaqMan-based real-time PCR assay was performed to detect the methylation levels of the SOX9 gene in 156 cervical scrapings, including 48 normal cervical scrapings, 30 scrapings with cervical intraepithelial neoplasia 1 (CIN1), 30 scrapings with CIN2-3 and 48 scrapings with squamous cell carcinoma (SCC). The methylation levels (methylation score) of the SOX9 gene increased significantly with the severity of cervical squamous lesions. The area under the receiver operating characteristic (ROC) curve (AUC) revealed that the methylation score of the SOX9 gene could be used to segregate SCC/CIN2-3 from CIN1/normal (AUC, 0.961; p=0.000). At the optimal cut-off value, a sensitivity of 92.3% and a specificity of 89.7% were obtained. In conclusion, SOX9 methylation is frequently involved in cervical carcinogenesis, and may provide a valuable molecular biomarker for early detection of cervical cancer. PMID:23064448

    The CPT project came to an end in December 2006 and its original scope is now shared among three new areas, namely Computing, Offline and Physics. In the physics area the basic change with respect to the previous system (where the PRS groups were charged with detector and physics object reconstruction and physics analysis) was the split of the detector PRS groups (the old ECAL-egamma, HCAL-jetMET, Tracker-btau and Muons) into two groups each: a Detector Performance Group (DPG) and a Physics Object Group. The DPGs are now led by the Commissioning and Run Coordinator deputy (Darin Acosta) and will appear in the correspond¬ing column in CMS bulletins. On the physics side, the physics object groups are charged with the reconstruction of physics objects, the tuning of the simulation (in collaboration with the DPGs) to reproduce the data, the provision of code for the High-Level Trigger, the optimization of the algorithms involved for the different physics analyses (in collaboration with the analysis gr...

  15. Muscular and skeletal changes in cervical dysphonic in women

    Menoncin, Laiza Carine Maia

    2010-12-01

    Full Text Available Introduction: The vocal and neck are associated with the presence of tension and cervical muscle contraction. These disorders compromise the vocal tract and musculoskeletal cervical region and, thus, can cause muscle shortening, pain and fatigue in the neck and shoulder girdle. Objective:To evaluate and identify cervical abnormalities in women with vocal disorders, and neck pains comparing them to women without vocal complaints independent of the neck. Method: This prospective study of 32 subjects studied in the dysphonic group and 18 subjects in the control group, aged between 25 and 55 year old female. The subjects underwent assessments, ENT, orthopedic, physical therapy and voice recording. Results: At Rx cervical region more patients in the control group had this normal, however, with regard to the reduction of spaces interdiscal dysphonic patients prevailed. Furthermore, postural assessment, the kyphosis of the 1st thoracic vertebra occurred in 77.0% of non-dysphonic group (p = 0.0091, while cervical rotation was present in 83% of control (p = 0.0051. Conclusion: Significant cervical abnormalities in both groups, but cannot be inferred that the changes are directly related to dysphonia.

    Cervical myelopathy is the most common cause of acquired spinal cord compromise. The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    Treatment-requiring diseases of the cervical spine in children are rare. The most common cases requiring medical assessment and treatment are acute torticollis and various accidents. A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

    A relation between apparent diffusion coefficient (ADC) values and tumor cellular density has been reported. The purpose of this study was to measure the ADC values of cervical cancers in the uterus and compare them with those of normal cervical tissues, and to test whether ADC could differentiate between normal and malignant cervical tissues in the uterus. Twelve consecutive female patients with cervical cancer of the uterus and ten female patients with other pelvic abnormalities were included in this study. ADC was measured at 1.5 T with b-factors of 0, 300 and 600 s/mm{sup 2} using single-shot echo-planar diffusion-weighted imaging and a parallel imaging technique. The mean ADC value of cervical cancer lesions was 1.09{+-}0.20 x 10{sup -3} mm{sup 2}/s, and that of normal cervix tissue was 1.79{+-}0.24 x 10{sup -3} mm{sup 2}/s (P<0.0001). In nine patients treated by chemotherapy and/or radiation therapy, the mean ADC value of the cervical cancer lesion increased significantly after therapy (P<0.001). The present study showed, with a small number of patients, that ADC measurement has a potential ability to differentiate between normal and cancerous tissue in the uterine cervix. Further study is necessary to determine the accuracy of ADC measurement in monitoring the treatment response. (orig.)

  4. A case of radiation induced carcinoma of the cervical esophagus

    International Nuclear Information System (INIS)

    A patient with carcinoma of the cervical esophagus who visited a hospital with a complaint of difficulty in swallowing was reported. This patient was a 50 year old woman. It was 32 years since she had had external irradiation with x- ray over the neck for Basedow's disease at the age of 18. From the age of 30, she had had hypothyroidism and had used thyroid. She became aware of difficulty in swallowing in October, 1976. Then this symptom progressed gradually, and she also had hoarseness. She visited a hospital in August, 1977. At the first medical examination, pigmentation and atrophic changes in the neck induced by radiation were observed, and some lymphnodes with the size of a red bean were palpated. Esophageal roentogenography revealed circular and spiral type lesion in the cervical esophagus, which was 4 cm in length and had a clear boundary. Endoscopic examination revealed circular stenotic lesion. This lesion was diagnosed as squamous cell carcinoma by biopsy. Total of 3,000 rad of Linac x-ray was irradiated over the neck and the clavicle before operation. Operation findings revealed fibrosis, atrophy, and hardening of the thyroid gland caused by radiation. Carcinoma with the size 35 mm x 18 mm was limited to the cervical esophagus, and the degree of the progress was A2, N2, M0 (Pl0). Histological findings revealed moderately differentiated squamous cell carcinoma and its metastases to the right supraclaviclar lymphnodes. This carcinoma was diagnosed as radiation-induced carcinoma of the cervical esophagus, because this patient had had irradiation over the neck, locally marked atrophic changes and scar remained, and carcinoma occurred in the area which had been irradiated with x-ray.

    Case-control study based on the immunohistochemistry for TGF-β1 evaluation of cervical samples obtained from two groups of women: CIN/HIV- and CIN/HIV+. Eleven women infected with HIV and with a histopathological diagnosis of CIN were included. The control group consisted of 12 patients with CIN. Cervical tissue samples obtained from all patients were submitted to histopathology and semiquantitative analysis of immunostaining for TGF-β1 protein. In addition, the peripheral CD4+ cell count and viral load were evaluated in HIV + patients. Tissue expression of the cytokine was higher in the CIN/HIV+ group compared to control (p = 0.0023). In addition, higher TGF-β1 expression was observed in higher grade cervical lesions in the two groups. There was a trend toward a direct correlation between peripheral CD4+ T cell count and tissue TGF-β1, and toward an inverse correlation between viral load and cytokine expression. Thus, TGF-β1 was more marked in situations in which cervical lesions are known to present a more aggressive behavior, suggesting that this cytokine is involved in the pathogenesis of tumor growth in these lesions. Tissue expression of TGF-β1 is increased in cervical samples from HIV-infected women with CIN. PMID:22542711

    Cervical intraepithelial neoplasia (CIN) refers to continuously precancerous lesions process from cervical epithelial atypical hyperplasia to carcinoma in situ. In recent years, the morbidity rates of CIN and cervical cancer have increased, and the patients tend to be younger. Therefore, it is important to have CIN correctly diagnosed and properly treated. The traditional Pap smear, thinprep cytology test (TCT), examination of human papilloma virus (HPV), colposcopy test, and cervical biopsy are the main diagnosing methods of CIN. Due to the features of high accuracy, non-invasion, and repeatable operation, colposcopy is the major method in diagnosis of cervical lesions. The common CIN treatment methods include physical therapy and operation therapy. CO2 laser therapy, cryotherapy, and electric coagulation therapy are included in the physical therapy, and cervical conization and hysterectomy are the operation therapy. Loop electrosurgical excision procedure (LEEP) has become the main treatment method for precancerous lesions of cervical cancer and early-stage cervical cancer, because of its characteristics of short treatment time, simple operation, less damage, deeper and wider range of lesions treatment, and pathological examination of the resected tissues.%宫颈上皮内瘤样病变(CIN)是指子宫颈上皮非典型增生至原位癌这一系列癌前病变的连续过程,近年CIN及宫颈癌的发病率增加且患者年龄趋于年轻化,因此及时正确诊断CIN并得到合适的治疗尤为重要。CIN的诊断有传统巴氏涂片法、液基细胞学(TCT)检查、人乳头瘤病毒(HPV)检查、阴道镜检查、宫颈活检等多种方法,其中阴道镜因其准确性高、无创伤、可重复操作等特点,是目前诊断宫颈病变的重要方法。常用的CIN治疗方法有物理治疗和手术治疗。物理治疗方法包括CO2激光治疗、冷冻治疗、电凝治疗等。手术治疗包括宫颈锥切术和全子宫切除术等

    Objective: To evaluate the clinical value of transvaginal elastography (TVES) in diagnosing cervical malignancies by detecting changes of tissue stiffness. Methods: One hundred and ten consecutive patients with cervical lesions were enrolled. Pathological results were used as the gold standards. TVES was employed to detect the stiffness changes of the cervix. Strain ratio was calculated and compared between the benign and malignant lesions. Depth of invasion into stromas of 56 cases of cervical cancers measured by TVES were recorded and compared with the pathological results. Interclass correlation coefficient (ICC) was used to analyze the reproducibility. Results: Strain ratio of malignant lesions were much higher than that of the benign lesions (8.19 {+-} 5.66 vs. 2.81 {+-} 2.24, P < 0.01). Area under the curve (AUC) was 0.905 with a 95% CI (0.835-0.976). The best cut-off point of strain ratio value was 4.53. Specificity and sensitivity for the best cut-off point were 0.788 and 0.897, respectively. Mean depth of the 56 malignant lesions was 17.8 {+-} 7.4 mm measured by TVES (range 5.4-43.1 mm) and 11.5 {+-} 8.8 mm measured by pathological samples (range 3.7-38.4 mm). ICC of the 2 methods were 0.87 (95% CI 0.863-0.947) and 0.931 (95% CI 0.902-0.952) for the 2 observers. Conclusions: TVES was a useful technique in confirming the diagnoses of cervical cancer and in estimating the infiltrating region. When the strain ratio of a cervical lesion was higher than 4.53, it is confidential to be diagnosed as malignant.

    The purpose of this study was to examine the relationship between the location of the cervical cord compression and the increased signal intensity within the cervical cord on T2-weighted imaging (T2WI) in patients with cervical myelopathy and myelomalacia. We reviewed 1,615 MRI reports from January 2011 to May 2013 from a single institution. Of the 1,615 reports reviewed, 168 patients were diagnosed with increased signal intensity within the cervical spine on T2WI. After applying the exclusion criteria 82 patients were included in the study. The MRIs of these 82 patients were then reviewed and the location of the increased signal intensity on T2WI in relation to the location of the pressure on the spinal cord was recorded. In more than 50 % of the cases the lesions with increased signal intensity on T2WI either were located distal to the pressure on the spinal cord or started at the level of the pressure and extended to an area distal to the pressure. In 26 out of the 92 lesions with increased signal intensity on T2WI, the lesion started proximal to the pressure on the spinal cord and extended distal to it. In only 3 out of the 92 lesions, the lesion with increased signal intensity on T2WI was solely located proximal to the pressure on the spinal cord. In 5 other cases the lesion with increased signal intensity on T2WI started proximal to the level of pressure on the spinal cord and extended into the level of pressure on the spinal cord (p < 0.001; Table 1). Cervical myelomalacia may appear proximal, distal or at the level of the compressed cord. It rarely appears solely proximal to the pressure area on the cord. (orig.)

    Full Text Available OBJECTIVE: Bacterial vaginosis (BV, the most common vaginal disorder among women of reproductive age, has been suggested as co-factor in the development of cervical cancer. Previous studies examining the relationship between BV and cervical intra-epithelial neoplasia (CIN provided inconsistent and conflicting results. The aim of this study is to clarify the association between these two conditions. METHODS: A systematic review and meta-analysis were conducted to summarize published literature on the association between BV and cervical pre-cancerous lesions. An extensive search of electronic databases Medline (Pubmed and Web of Science was performed. The key words 'bacterial vaginosis' and 'bacterial infections and vaginitis' were used in combination with 'cervical intraepithelial neoplasia', 'squamous intraepithelial lesions', 'cervical lesions', 'cervical dysplasia', and 'cervical screening'. Eligible studies required a clear description of diagnostic methods used for detecting both BV and cervical pre-cancerous lesions. Publications were included if they either reported odds ratios (OR and corresponding 95% confidence intervals (CI representing the magnitude of association between these two conditions, or presented data that allowed calculation of the OR. RESULTS: Out of 329 articles, 17 cross-sectional and 2 incidence studies were selected. In addition, two studies conducted in The Netherlands, using the national KOPAC system, were retained. After testing for heterogeneity and publication bias, meta-analysis and meta-regression were performed, using a random effects model. Although heterogeneity among studies was high (χ(2 = 164.7, p<0.01, I(2 = 88.5, a positive association between BV and cervical pre-cancerous lesions was found, with an overall estimated odds ratio of 1.51 (95% CI, 1.24-1.83. Meta-regression analysis could not detect a significant difference between studies based on BV diagnosis, CIN diagnosis or study population

    Full Text Available The anterior retropharyngeal approach (ARPA accesses anteriorly situated lesions from the clivus to C3, in patients with a short neck, Klippel Feil anomaly or those in whom the C2-3 and C3-4 disc spaces are situated higher in relation to the hyoid bone and the angle of mandible where it is difficult to approach this region using the conventional anterior approach, due to the superomedial obliquity of the trajectory. The ARPA avoids the potentially contaminated oropharyngeal cavity providing for a simultaneous arthrodesis and instrumentation during the primary surgical procedure. Experience of five patients with high cervical extradural compression, who underwent surgery using this approach between 1994 and 1999, is presented. The surgical procedures included excision of ossified posterior longitudinal ligament (n=2; excision of prolapsed disc and osteophytes (n=2; and excision of a vertebral body neoplasm (n=1. Following the procedure, vertebral arthrodesis was achieved using an iliac graft in all the patients. Only one patient with vertebral body neoplasm required an additional anterior cervical plating procedure for stabilisation the construct. The complications included transient respiratory insufficiency and neurological deterioration in two patients; and, pharyngeal fistula and donor site infection in one patient.

    Overhead intermittent cervical traction is often utilized to control the symptoms of cervical radiculopathy associated with osteoarthritis. The long-term home use of presently available counterweight systems has often presented problems including: (1) lack of patient compliance, (2) difficulty with application by elderly or debilitated patients, (3) tensing of both the cervical paraspinalis and upper extremity muscles while maneuvering the counterweights, and (4) discomfort while using the device. A prototype home pneumatic traction device was developed, which has many of the advantages of the expensive hydraulic units in common use in physical therapy departments. The initial favorable responses of 17 patients led to the development of a prototype commercial unit in cooperation with the Jobst Company. Of 36 patients who used the pneumatic traction device at home, 29 (81%) preferred it to the conventional counterweight system. Typical reasons were that it was easier to use, more "workable" and provided a steadier pull with more gradual onset of traction. Disadvantages most commonly mentioned were minor air pressure loss in the hand pump model and the complexity of the unit. The most rational approach to the use of these new pneumatic devices would be to initiate a home traction program using conventional counterweight units and then to switch to the pneumatic unit for long-term patients or those who are unable to apply conventional traction systems unassisted.

    Full Text Available Tuberculosis of the cervix is a rare disease and accounts to 0.1 – 0.65% of all cases of tuberculosis and 5 – 24 % of genital tract tuberculosis. We present an unusual case of 40 years old lady who presented with irregular bleeding per vagina and foul smelling white discharge for 1 year. Per speculum examination revealed an unhealthy looking cervix which bled on touch. A clinical diagnosis of carcinoma cervix was made. However, cervix biopsy revealed granulomatous lesion suggestive of tuberculosis. The patient responded to antitubercular therapy. In women with abnormal cervical appearance, there should be high index of suspicion of tuberculosis cervix, especially from areas where tuberculosis is common as it can be easily treated.

    Cervical cancer (CC) is a major public health problem in developing countries and its most significant etiological risk factor is infection by the human papillomavirus (HPV). The main approach to date for the prevention of CC has been through screening programs, using the cervical smear (PAP test) to detect precursory lesions. The sensitivity and specificity of the PAP smear depend on the skills of the observer to recognize and classify a variety of cellular abnormalities. The development of ...

    Cervical pseudomeningocele is a rare complication of trauma. It develops when an extradural collection of cerebrospinal fluid (CSF) develops after a dural breach. The authors present the unusual case of a 33-year-old man with progressive headache, neck pain, mental status changes, and cardiopulmonary instability after polytrauma sustained from a motorcycle-versus-deer collision, without improvement during a 5-day hospitalization. Magnetic resonance imaging revealed a collection of CSF anterior to the cervical thecal sac compatible with an anterior cervical pseudomeningocele. A nontargeted epidural blood patch was performed with subsequent resolution of the patient's symptoms. Anterior cervical pseudomeningoceles are usually asymptomatic; however, these lesions can cause orthostatic headaches, neck pain, and cardiopulmonary compromise, as it did in the featured patient. Pseudomeningoceles should be included in the differential diagnosis for posttrauma patients with progressive neurological decline or postural headache, and blood patch may be an effective minimally invasive treatment.

    Full Text Available Abstract Cervical dysplasia is a premalignant lesion associated with human papillomavirus (HPV infection which, over time, can turn cancerous. Previous studies have indicated that loss of gap junctions may be a feature of cervical cancer and premalignant dysplasia. Loss of the gap junction protein connexin43 has been demonstrated in dysplastic cervix, but other connexins have not been investigated. In contrast we previously showed that HPV-associated cutaneous warts – and other hyperproliferative skin conditions – display a dramatic upregulation of certain connexins, in particular connexin26. By performing immunofluorescence staining after antigen retrieval of paraffin-embedded cervical tissue samples, this study reports for the first time that connexin26 and connexin30, in addition to connexin43, are expressed in differentiating cells of normal human cervical epithelia. Moreover, in dysplastic ectocervix, all connexins studied display a dramatic loss of expression compared to adjacent normal epithelia. The role of connexins in keratinocyte differentiation and carcinogenesis is discussed.

    Objective: Spinal cord swelling with abnormal gadolinium (Gd) enhancement is a rare preoperative radiological finding in patients with cervical spondylosis. In the presence of progressive myelopathy, timely surgical decompression can be curative. Case presentation: We report 3 patients with cervical spondylotic myelopathy. Preoperative magnetic resonance imaging (MRI) revealed spondylotic changes and intramedullary lesions in the cervical spine. We noted cervical cord swelling with high intensity on T2-weighted MRI and abnormal Gd-DTPA enhancement. Laminoplasty resulted in marked improvement of their neurological condition and postoperative MRI revealed gradual regression of the intramedullary lesions during the first year. Conclusion: We posit that the intramedullary lesions in our patients were reflective of spinal cord edema with blood-brain-barrier disturbance in the cervical cord, possibly due to minor recurrent spinal cord injury and disturbed venous circulation. Spinal cord edema is a rare condition in patients with cervical spondylosis and an accurate diagnosis and timely surgery are necessary for cure. Therefore, this unusual condition must be considered in spondylosis patients manifesting as intramedullary lesions on MRI of the cervical spinal cord. Careful evaluation of the postoperative course can be used to confirm the diagnosis and help in selecting a subsequent therapeutic strategy. PMID:22028753

    2006-01-01

    Objective To evaluate the overexpression of cyclin G1 in cervical intraepithelial neoplasia (CIN) and cervical carcinoma, and the correlation between cyclin G1 and high-risk human papilloma virus (HPV) infection.Methods All of the specimens were obtained from the Department of Pathology of China-Japan Friendship Hospital from January 2000 to August 2004. We detected the expression of cyclin G1 with immunohistochemistry, HPV16/18infection with in situ hybridization, and high-risk HPV infection with Hybrid capture system Ⅱ (HC-Ⅱ) in normal group (25 cases), CIN Ⅰ (48 cases), CIN Ⅱ (56 cases), CIN Ⅲ (54 cases), and invasive cervical squamous-cell carcinoma (SCC, 31 cases).Results The positive rates of cyclin G1 expression in CIN (77. 85%) and SCC cervical tissues (87.10%) were significantly higher than normal (8.00%,P<0.01), and the intensities of cyclin G1 expression in CIN (40.60%)and SCC cervical tissues (61.51%) were significantly higher than normal (2.72%,P<0.05). The positive rates and intensities of cyclin G1 expression increased gradually with the grade of cervical lesions. High-risk HPV infection rates were higher in CIN and SCC than normal groups (P<0.05). There was a positive correlation between cyclin G1 expression and high-risk HPV infection detected with HC-Ⅱ (Kendall's tau-b =0.316, 0.269, 0.352, and 0. 474 in CIN Ⅰ, CINⅡ, CIN Ⅲ, and SCC, respectively, P<0.05).Conclusions Cyclin G1 is overexpressed in CIN and SCC. Cyclin G1 may be a biomarker for detecting CIN and SCC. Cyclin G1 may play an important role in the oncogenesis of CIN and SCC by high-risk HPV infection.

  5. Probability of a cure of cervical cancer with relation to its stage and size

    International Nuclear Information System (INIS)

    A method for calculation of sizes of lesions at different stages (T) of cervical cancer, their correlation and the comparison of 5-year survival rates after combined therapy was proposed. The above method based on the sizes of anatomical structures, proved to be very important for analysis of the efficacy of cervical cancer therapy. Substaging was clinically substantiated because it reflected some peculiarities in tumor spreading with relation to a tumor size. Tumor sizes could differ significantly within the same stage and coincide at different stages entailing a possible difference in therapeutic results. The 5-year survival rate of cervical cancer patients with a lesion size of 1 cm3 was over 80%, and with an increase in tumor sizes over 15 cm3 it was under 50%. When a tumor was 80 cm3 and more in size its cure was highly improbable

    International Nuclear Information System (INIS)

    In the course of life the periodontum is subject to changes which may be physiological or pathological. Intraoral radiographs give insight into the hard structures of the dentomaxillar region and provides information on lesions in the bone of the periodontum in that they show radiopacities and radiolucencies caused by such lesions. In this thesis the relation is investigated between the true shape and dimensions of periodontal bone lesions and their radiographic images. A method is developed and tested of making standardized and reproducible radiographs suitable for longitudinal studies of periodontal lesions. Also the possibility is demonstrated of an objective and reproducible interpretation of radiographic characteristics of periodontal bone lesions. (Auth.)

    Full Text Available BACKGROUND: Cervical intra - epithelial neoplasia (CIN and cervical cancer remain important health problems for women worldwide. It is largely a preventable disease that is characterized by a long lead time. The objective of this study was to determine the frequency of precancerous lesions of cervix by Pap smear screening. METHODS : A retrospective hospital based study was conducted at Department of Pathology, in a Tertiary Care Institute and associated hospital, Bhopal. Data was collected from the records of Pap’s smear testing done on 388 patients in years 2011 & 2012. Analysis was done by entering data in SPSS software and Chi - square test was applied to find statistical significance. RESULTS: Most common lesions on Pap’s smear was Low grade squamous intraepithelial les ion (LSIL in 104 (26.8% of cases and High grade squamous intraepithelial lesion (HSIL in 15 (3.9% of cases. 44 (11.3% were senile Atopic Changes, parasitic Infection in 27 (7% of cases and 2 (0.5% were carcinoma cervix cases. All the cervical lesion s were most common in age of 31 - 40 yrs. and were significantly associated with age. CONCLUSIONS: Pap’s smear examination information should be spread in community apart from hospitals. Especially the young women should be motivated for regular Pap’s smear. Pap’s smear is the single most important screening method for early detection of precancerous & cancerous cervical lesions

    Screening for the cancer of the cervix remains a neglected health care issue in Pakistan. To provide baseline data for future efforts to improve screening, we conducted a retrospective analysis of cervical smears taken in the obstetrics and gynaecological clinics of the Agha Khan University Hospital, Karachi, Pakistan. We collected data on cervical smear cytology for cervical smears taken from January 1, 1990 to December 31, 1996. We assessed risk factors for dysplasia, including age, age at first marriage, and number of pregnancies. The overall prevalence of abnormal smears in our study was 0.5%. Of 20,995 cervical smears, showed non-specific inflammation, 7302 (34.8%) were reported as normal, 809 (3.85%) showed monillial infection, 148 (0.71%) showed atypia, 105 (0.5%) had dyplastic cytology and 52 (0.25%) samples were inadequate. The highest incidence of dysplastic smears was seen in the age group 35 to 44 years. Of 105 patients with dysplasia 12 were pregnant, and all were asymptomatic. The low prevalence of abnormal smears, compared with the data from Western populations, could be due to the internet bias of health awareness in the women who attended our hospital. The results of this study may serve as baseline for for future comparisons. A large community-based study may establish the exact prevalence of malignant and premalignant lesions so as to plan for future screening. (author)

    Cervical cancer and its precursor intra-epithelial lesions are linked to infection by a subset of so-called "highrisk" human papillomavirus types, which are estimated to infect nearly four hundred million women worldwide. Two prophylactic vaccines have been commercialized recently targeting HPV16 and 18, the most prevalent viral types found in cervical cancer, which operate through induction of capsid-specific neutralizing antibodies. However, in patients with persistent infection these vaccines have not been found to protect against progression to neoplasia. Attempts are being made to develop therapeutic vaccines targeting nonstructural early viral proteins. Among these, E6 and E7 are the preferred targets, since they are essential for induction and maintenance of the malignant phenotype and are constitutively expressed by the transformed epithelial cells. Here are reviewed the most relevant potential vaccines based on HPV early antigens that have shown efficacy in preclinical models and that are being tested in clinical studies, which should determine their therapeutic capacity for eradicating HPV-induced premalignant and malignant lesions and cure cervical cancer.

    Previously, we reported that in a sample of 14 healthy persons the analysis of the slow movement of the forefinger against a predetermined force presented a behavior that qualitatively is present in all subjects and it is characterized by three parameters: 1) a positive pulsating phase pattern of velocity; 2) pulses of low amplitude are more frequent; 3) a spectral pattern with a frequencies distributed in a wide interval. Now we report the value of physical work developed by the forefinger by unitary distance. We determine the fractal dimension of the velocity time series using the Higuchi method, and the multifractal analysis of the movement pattern. On the other hand, applying these methods to a person with nervous system pathology we find that its movement pattern is clearly different compared with that of a normal person.

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    Full Text Available Abstract Background Claspin is a nuclear protein involved in DNA replication and damage response and is a key mediator for the S-phase checkpoint. Claspin expression is significantly high in several human solid tumors. Furthermore, high levels of claspin have been found in cervical cancer cell lines. Nevertheless, no data are available regarding claspin expression in cervical tissues. Methods In order to investigate whether claspin immunoreactivity is related to the lesion severity and High-Risk (HR HPV infection, we analyzed claspin expression by immunohistochemistry in a series of cervical biopsies which represent the steps occurring during cervical carcinogenesis (normal tissues, Cervical Intraepithelial Neoplasias 1, 2 and 3, Squamous Cell Carcinomas. All patients also had a cervico-vaginal sample for HPV testing, collected immediately before the colposcopy-guided biopsy. The HR-HPV DNA detection was performed by the HR-HPV Hybrid Capture 2 test. HPV genotyping was performed using the Linear Array HPV Genotyping Test. Results Our results evidenced a constant and significant increase of the rate of claspin positivity from the normal tissues to carcinomas (pχ2trend 2  Conclusions Our findings indicate that in vivo claspin expression is significantly related to HR-HPV infection and lesion grade both in histological and cytological samples. Therefore, the analysis of claspin expression could be clinically relevant in the diagnosis of HPV-related cervical lesions, in particular when applied to cervico-vaginal cytology. Moreover, giving information on the proliferation rate of each lesion, claspin immunostaining may contribute to the evaluation of progression risk, thus being helpful in patient management. Nevertheless, only large prospective studies may clarify the true clinical usefulness of claspin expression in distinguishing lesions with different progression potential.

    Cervical cancer is a worldwide disease that constitutes a significant public health problem, especially in developing countries, not only due to its high incidence but also because the most affected population comprises women who belong to marginalized socio-economic classes. Clinical and molecular research has identified immunological impairment in squamous intraepithelial cervical lesions and cervical cancer patients. Human Papillomavirus (HPV) has several mechanisms for avoiding the immune system: it down-regulates the expression of interferon and upregulates interleukin (IL)-10 and transforming growth factor (TGF)-β1 to produce a local immunosuppressive environment, which, along with altered tumor surface antigens, forms an immunosuppressive network that inhibits the antitumor immune response. In this review we analyzed the available data on several deregulated cellular immune functions in patients with NIC I, NIC II and NIC III and cervical cancer. The effects of immunosuppressive cytokines on innate immune response, T-cell activation and cellular factors that promote tumor cell proliferation in cervical cancer patients are summarized. We discuss the functional consequences of HPV E2, E6, and E7 protein interactions with IL-10 and TGF-β1 promoters in the induction of these cytokines and postulate its effect on the cellular immune response in squamous intraepithelial cervical lesions and cervical cancer patients. This review provides a comprehensive picture of the immunological functions of IL-10 and TGF-β1 in response to HPV in humans. PMID:25302175

    Cervical spondylosis is a common and disabling condition. It is generally felt that the initial management should be nonoperative, and these modalities include physiotherapy, analgesia and selective nerve root injections. Surgery should be reserved for moderate to severe myelopathy patients who have failed a period of conservative treatment and patients whose symptoms are not adequately controlled by nonoperative means. A review of the literature supporting various modalities of conservative management is presented, and it is concluded that although effective, nonoperative treatment is labour intensive, requiring regular review and careful selection of medications and physical therapy on a case by case basis.

    Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation.

    Full Text Available Cervical spondylosis is a common, chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck as well as the contents of the spinal canal. Common clinical syndromes associated with cervical spondylosis include cervical pain, cervical radiculopathy and/or mielopathy. This study show the main principles, indication and side effects of tuina in cervical spondylosis´ treatment; tuina is one of the external methods based on the principles of Traditional Chinese Medicine (TCM, especially suitable for use on the elderly population and on infants. While performing Tuina, the therapist concentrates his mind, regulates his breathing, and actuates the Qi and power of his entire body towards his hands. For a better result is recommended to try to combine acupuncture with tuina treatment. Tuina can help relieve the pain associated with spondylosis. After this kind of treatment, the symptomes produced by irritated nerves and sore muscles can find some relief. Tuina helps patients with cervical spondylosis regain muscle control, nerve function and flexibility, all through the restoration of the life force flow.

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    Several different physics procedures have been tried to mechanize the recording of partograms. Can a measure of impedance of tissue Z using potential difference V, according to Ohm's law V = Z1, and 1 is a constant, be correlated with a measure of cervical dilatation using vaginal examination? This was our hypothesis. The tissue impedance meter was made to our design and applied according to a bipolar procedure. Our work was carried out on 28 patients. 10 patients were registered before labour started in order to test the apparatus and to record the impedance variations without labour taking place, and 18 patients were registered in labour to see whether there was any correlation. The level of impedance in the cervix without labour was 302.7 Ohms with a deviation of 8.2. Using student's t tests it was found that there was a significant correlation (p less than 0.001) in four measurements between the impedance measure and measures obtained by extrapolating the degrees of dilatation calculated from vaginal examination. This is a preliminary study in which we have defined the conditions that are necessary to confirm these first results and to further develop the method. PMID:1401774

    This is an analysis of 34 patients with carcinoma of the cervical esophagus treated with radiation therapy with curative intent at the University of Florida between September 1966 and May 1985. All patients have a minimum 2-year follow-up and 28 (82%) have at least 5 years of follow-up. Patients were staged according to the recommendations of the AJCC. Patients who died within 2 years of treatment with the primary site continuously disease-free were excluded from the local control analysis; all patients were included in the analysis of complications and survival. Irradiation resulted in control of the primary lesion in 1 of 2 patients who presented with T1 lesions, in 4 of the 12 patients with T2 lesions, and 3 of 17 patients who presented with T3 lesions. One patient with a T3 lesion that recurred locally was successfully salvaged by an operation. The 5-year absolute survival rates by stage were as follows: no patients with stage I lesions survived; of 11 stage II patients, one survived; and of 16 stage III patients, three survived. Interestingly, all four of the 5-year survivors were women.

    Cervical intraepithelial neoplasia (CIN) is the precursor of invasive cervical cancer and associated with human papillomavirus (HPV) infection. Photodynamic therapy (PDT) is a technique that has been used for the treatment of tumors. PDT is based on the accumulation of a photosensitizer in target cells that will generate cytotoxic reactive oxygen species upon illumination, inducing the death of abnormal tissue and PDT with less damaging to normal tissues than surgery, radiation, or chemotherapy and seems to be a promising alternative procedure for CIN treatment. The CIN high grades (II and III) presents potential indications for PDT due the success of PDT for CIN low grade treatment. The patients with CIN high grade that were treated with new clinic protocol shows lesion regression to CIN low grade 60 days after the treatment. The new clinical protocol using for treatment of CIN high grade shows great potential to become a public health technique.

      The period since the last CMS Bulletin has been historic for CMS Physics. The pinnacle of our physics programme was an observation of a new particle – a strong candidate for a Higgs boson – which has captured worldwide interest and made a profound impact on the very field of particle physics. At the time of the discovery announcement on 4 July, 2012, prominent signals were observed in the high-resolution H→γγ and H→ZZ(4l) modes. Corroborating excess was observed in the H→W+W– mode as well. The fermionic channel analyses (H→bb, H→ττ), however, yielded less than the Standard Model (SM) expectation. Collectively, the five channels established the signal with a significance of five standard deviations. With the exception of the diphoton channel, these analyses have all been updated in the last months and several new channels have been added. With improved analyses and more than twice the i...

    The collisions last year at 900 GeV and 2.36 TeV provided the long anticipated collider data to the CMS physics groups. Quite a lot has been accomplished in a very short time. Although the delivered luminosity was small, CMS was able to publish its first physics paper (with several more in preparation), and commence the commissioning of physics objects for future analyses. Many new performance results have been approved in advance of this CMS Week. One remarkable outcome has been the amazing agreement between out-of-the-box data with simulation at these low energies so early in the commissioning of the experiment. All of this is testament to the hard work and preparation conducted beforehand by many people in CMS. These analyses could not have happened without the dedicated work of the full collaboration on building and commissioning the detector, computing, and software systems combined with the tireless work of many to collect, calibrate and understand the data and our detector.

    The Physics Groups are actively engaged on analyses of the first data from the LHC at 7 TeV, targeting many results for the ICHEP conference taking place in Paris this summer. The first large batch of physics approvals is scheduled for this CMS Week, to be followed by four more weeks of approvals and analysis updates leading to the start of the conference in July. Several high priority analysis areas were organized into task forces to ensure sufficient coverage from the relevant detector, object, and analysis groups in the preparation of these analyses. Already some results on charged particle correlations and multiplicities in 7 TeV minimum bias collisions have been approved. Only one small detail remains before ICHEP: further integrated luminosity delivered by the LHC! Beyond the Standard Model measurements that can be done with these data, the focus changes to the search for new physics at the TeV scale and for the Higgs boson in the period after ICHEP.

Planning for the upcoming higher luminosity/higher energy (8 TeV) operation of the LHC and relatively early Rencontres de Moriond are the high-priority activities for the group at the moment. To be ready for the coming 8-TeV data, CMS has made a concerted effort to perform and publish analyses on the 5 fb−1 dataset recorded in 2011. This has resulted in the submission of 16 papers already, including nine on the search for the Higgs boson. In addition, a number of preliminary results on the 2011 dataset have been released to the public. The Exotica and SUSY groups approved several searches for new physics in January, such as searches for W′ and exotic highly ionising particles. These were highlighted at a CERN seminar given on 24th  January.

    Physics-wise, the CMS week in December was dominated by discussions of the analyses that will be carried out in the “next six months”, i.e. while waiting for the first LHC collisions.  As presented in December, analysis approvals based on Monte Carlo simulation were re-opened, with the caveat that for this work to be helpful to the goals of CMS, it should be carried out using the new software (CMSSW_2_X) and associated samples.  By the end of the week, the goal for the physics groups was set to be the porting of our physics commissioning methods and plans, as well as the early analyses (based an integrated luminosity in the range 10-100pb-1) into this new software. Since December, the large data samples from CMSSW_2_1 were completed. A big effort by the production group gave a significant number of events over the end-of-year break – but also gave out the first samples with the fast simulation.

  20. Clinical Usefulness of serum total cholesterol as an index of hypothyroidism in patients after cervical radiation

    International Nuclear Information System (INIS)

    Cervical radiation therapy is often applied to patients with head and neck cancers because radiation has a high sensitivity to these cancers and permits the preservation of functions and physical form. However, it has been shown that various complications can result from radiation therapy. We have encountered some patients who showed hypercholesterolemia resulting from cervical radiation. Therefore, we have paid close attention to the relationship between hypercholesterolemia after cervical radiation and hypothyroidism. Thyroid hormone tests in these patients with hypercholesterolemia after cervical radiation showed high thyroid stimulating hormone (TSH) and low free thyroxine (fT4), indicating the presence of hypothyroidism. After administration of levothyroxine Na, their fT4 levels increased and both TSH levels and serum total cholesterol levels decreased. In conclusion, in patients who have received cervical radiation, we recommend monitoring serum total cholesterol periodically to detect hypothyroidism easily before the appearance of its symptoms.

    In summary, it is important for physicians dealing with neck pain in an athletic population to understand the differences between serious and mild cervical injuries. This is best facilitated by a thorough understanding of the signs and symptoms of serious cervical injury, familiarity with the basic anatomy of the neck and its structures, and a working knowledge of common causes of neck pain and mechanisms of injury. All unconscious athletes should be assumed to have a serious cervical injury until proven otherwise, and preventive measures should be taken to ensure the safety of the athlete. This includes airway management with a jaw thrust only, neck stabilization, and preventing helmet removal. In the conscious athlete who has neck pain, serious cervical injury can often be ruled out with an accurate history and physical examination. In all cases of neck pain, it is imperative that the athlete be protected. This may involve removing the athlete from competition, or transporting him or her to the local emergency room. Often, this decision falls on the shoulders of the doctor in the stands. Thus, a basic understanding of the evaluation and management of neck pain in athletes is an asset for all physicians who frequent athletic events or see athletes in the office. The physician responsible for patients who have Down syndrome or rheumatoid arthritis needs to consider the increased incidence of cervical instability in these patients when evaluating for athletic participation or neck pain.

  6. Prevalence of Human Papilloma Virus Infection in Malignant Lesions of the Uterine Cervix in Morocco

    International Nuclear Information System (INIS)

    Cervical cancer is one of the most common tumors afflicting women with a disproportionate mortality occurring in developing countries. The aim of this study was to determine the prevalence of high-risk oncogenic human Papilloma viruses (HPVs) in 193 archival cervical lesions of Moroccan women. The presence of high-risk HPVs in paraffin-embedded, formaldehyde-fixed cervical lesion specimens was detected by Polymerase Chain Reaction (PCR) using consensus primers complementary to late 1 (L1) gene of the genital HPVs. Amplified PCR products were verified and typed by Southern blot analysis using P-32 labeled DNA probes. HPV prevalence was found to be 89% in malignant lesions (138/155) and 68.4% in premalignant lesions (26/38). HPV 16 was detected in 61% (100/164); whereas HPV 18 in 33.5% (55/164), HPV 31 in 1.8% (3/164), HPV 33 in 1.2% (2/164), HPV 35 in 7.3% (12/164), and HPV 45 in 3.7 % (6/164) of lesions. Notably, multiple HPV type co-infections occurred only in malignant lesions and were present in 20.1% (33/164) of cases. The most common co-infection was HPV types 16 and 18, followed by HPV types 16 and 35. Thus, a high prevalence of HPV16/18 was observed in archival cervical cancers. Hence, relevant HPV typing information in cervical cancer is very important for further HPV vaccines design and application. (author)

    Although cervical spondylotic myelopathy is a common cause of chronic spinal cord dysfunction in humans, little is known about the molecular mechanisms underlying the progressive neural degeneration characterized by this condition. Based on animal models of cervical spondylotic myelopathy and traumatic spinal cord injury, we hypothesized that Fas-mediated apoptosis and inflammation may play an important role in the pathobiology of human cervical spondylotic myelopathy. We further hypothesized that neutralization of the Fas ligand using a function-blocking antibody would reduce cell death, attenuate inflammation, promote axonal repair and enhance functional neurological outcomes in animal models of cervical spondylotic myelopathy. We examined molecular changes in post-mortem human spinal cord tissue from eight patients with cervical spondylotic myelopathy and four control cases. Complementary studies were conducted using a mouse model of cervical spondylotic myelopathy (twy/twy mice that develop spontaneous cord compression at C2-C3). We observed Fas-mediated apoptosis of neurons and oligodendrocytes and an increase in inflammatory cells in the compressed spinal cords of patients with cervical spondylotic myelopathy. Furthermore, neutralization of Fas ligand with a function-blocking antibody in twy/twy mice reduced neural inflammation at the lesion mediated by macrophages and activated microglia, glial scar formation and caspase-9 activation. It was also associated with increased expression of Bcl-2 and promoted dramatic functional neurological recovery. Our data demonstrate, for the first time in humans, the potential contribution of Fas-mediated cell death and inflammation to the pathobiology of cervical spondylotic myelopathy. Complementary data in a murine model of cervical spondylotic myelopathy further suggest that targeting the Fas death receptor pathway is a viable neuroprotective strategy to attenuate neural degeneration and optimize neurological recovery

    Notalgia paresthetica (NP) is a common refractory, sensory, neuropathic syndrome with the hallmark symptom of localized pruritus of the unilateral infrascapular back. It generally is a chronic noncurable condition with periodic remissions and exacerbations. While the dermatologic syndrome may be multifactorial in etiology, a possible association with underlying cervical spine disease should be evaluated for proper treatment. Collaborative multispecialty evaluation by dermatology, radiology, orthopedic surgery, and neurology may be indicated for primary management of this condition. First-line therapy for NP with associated cervical disease may include nondermatologic noninvasive treatments such as spinal manipulation, physical therapy, massage, cervical traction, cervical muscle strengthening, and oral nonsteroidal anti-inflammatory drugs and muscle relaxants. Notalgia paresthetica may in fact be a cutaneous sign of an underlying degenerative cervical spine disease. We report a case of a patient with cervical spinal stenosis that corresponded directly with the clinical findings of NP. PMID:20349681

We had more than 40 presentations at the Workshop, which was an important milestone for 2007 physics analyses in the EWK and TOP areas. The Standard Model has been tested empirically by many previous experiments. Observables which are nowadays known with high precision will play a major role for data-based CMS calibrations. A typical example is the use of the Z to monitor electron and muon reconstruction in di-lepton inclusive samples. Another example is the use of the W mass as a constraint for di-jets in the kinematic fitting of top-quark events, providing information on the jet energy scale. The predictions of the Standard Model, for what concerns proton collisions at the LHC, are accurate to a level that the production of W/Z and top-quark events can be used as a powerful tool to commission our experiment.

    This study reports 7 cases of cervical Pott's disease, gathered during 6 years in the department of neuro-surgery of Ibn Rochd U.H.C. 4 females and 3 males, aged between 9 and 52 years were included. All the patients complained of cervicobrachial pain and weakness of the limbs. Clinical features were: deterioration of general status, rachidian syndrome and neurological impairement with motor and sensitive deficit. Radiological analysis found a destructive and extensive lesion, cervical kyphosis from 10 degrees to 60 degrees, retropharyngeal abscess and intraspinal canal extension of infection. Diagnosis was confirmed by histological study in all cases. In addition to antituberculous therapy and preoperative cervical traction in 4 cases, all the patients had spinal fusion using an anterior approach. Post operative immobilization in a cervical collar varied from 9 to 12 months. All 7 patients had full neurological recovery, 6 patients had an excellent bony fusion and cervical kyphosis was corrected. For the remaining patient, the bone graft was mobilized without neurological disorders. This study confirms anterior arthrodesis efficiency. This procedure in conjunction with preoperative traction, allowed stabilization of the spine and healing of vertebral lesions with excellent kyphosis correction. PMID:9452797

To our knowledge, only one case of thoracic IBG has been reported previously, and our case is the first in cervical spine. A 35-year-old female patient was admitted with headache, pain and weakness in her four extremities. She had no gastrointestinal symptoms and fever. She had been diagnosed with Brucella meningitis 3 months ago and a triple therapy of doxycyclin, rifampicin and trimetoprim/sulfametoxazol (TMP/SMZ) had been started. Medical history revealed that she had ingested raw cheese and taken her medication improperly. Loss of strength was detected in her four extremities, which led us to assume the formation of a mass lesion at cervical level. Therefore, we performed a magnetic resonance imaging scan and found enhancement of an intramedullary mass lesion at cervical 1-2 level. Diagnosis of neurobrucellosis was confirmed by titer of >1/160 Brucella antibodies both in blood and cerebrospinal fluid. Based on these findings, brucellar granuloma of cervical spine was diagnosed and a combination therapy of doxycyclin, TMP/SMZ and rifampicin was administered for additional 6 months. At the ninth month of treatment, the patient recovered both radiologically and clinically. Our case is unique, in terms of cervical IBG formation. The excellent response to antimicrobial therapy in our patient suggests that, a trial of medical treatment for 6 months may be effective in such cases. PMID:17103231

  16. High Smac/DIABLO expression is associated with early local recurrence of cervical cancer

    International Nuclear Information System (INIS)

    In a recent pilot report, we showed that Smac/DIABLO mRNA is expressed de novo in a subset of cervical cancer patients. We have now expanded this study and analyzed Smac/DIABLO expression in the primary lesions in 109 cervical cancer patients. We used immunohistochemistry of formalin-fixed, paraffin-embedded tissue sections to analyze Smac/DIABLO expression in the 109 primary lesions. Seventy-eight samples corresponded to epidermoid cervical cancer and 31 to cervical adenocarcinoma. The median follow up was 46.86 months (range 10–186). Smac/DIABLO was expressed in more adenocarcinoma samples than squamous tumours (71% vs 50%; p = 0.037). Among the pathological variables, a positive correlation was found between Smac/DIABLO immunoreactivity and microvascular density, a marker for angiogenesis (p = 0.04). Most importantly, Smac/DIABLO immunoreactivity was associated with a higher rate of local recurrence in squamous cell carcinoma (p = 0.002, log rank test). No association was found between Smac/DIABLO and survival rates. Smac/DIABLO expression is a potential marker for local recurrence in cervical squamous cell carcinoma patients

    Full Text Available It is widely accepted that only persistent infection with high risk types of Human Papillomavirus (HPV HR is a significant risk factor for the development of an invasive squamous cervical cancer. The overexpression of viral oncogenes E6/E7 of HPV is considered a necessary process for incurring in a malignant phenotype.A HPV infection can be identified by detection of HPV DNA in biological samples, but the DNAbased tests cannot delineate between transient or persistent and potentially transforming infection. Instead there is many evidence to suggest that detection of HPV gene expression may constitute a more specific approach to highlight a clinically significant infection. Especially seems that the detection of E6/E7 transcripts can be usefully used for identify the women with a persistent HPV infection that will can induce a future cervical cancer. The aim of our study is to investigate if the detection of oncogenic viral gene activity by detecting transcripts of the E6 and E7 genes can be most usefull of HPV-DNA test in the triage of ASCUS or low grade cervical lesions. Our results confirm that HPV E6/E7 mRNA test can be considered a promising method to stratify HPV positive women for risk of future high-grade cervical lesions or cervical intaepithelial neoplasia.

  18. Magnetic resonance imaging of spinal lesions in multiple sclerosis

    International Nuclear Information System (INIS)

    We were able to detect spinal lesions by MRI (magnetic resonance imaging) in three cases of multiple sclerosis with suspected cervical spinal lesions. In two cases MRI was examined during relapse. MRI revealed marked swelling of the spinal cord. The lesions had low MRI-signal intensity in inversion-recovery images and high signal intensity in T2-weighted spin-echo images. As symptoms improved, a later MRI revealed that the spinal cord became thinner and signal intensity normalized. Prolongation of T1 relaxation time is said to be useful in evaluating lesion activity, but from our observations, T2-weighted images were more effective in detecting the earliest lesions of multiple sclerosis. We thought the MRI changes were due to edema because the time course of proton relaxation time resembled that in the experimental studies of brain edema reported previously and because in one case the swelling of the spinal cord and high signal areas on spin-echo image disappeared so rapidly in response to anti-edema therapy. In the last case MRI was examined in the remission phase. Although the spinal cord was almost normal in size, skip lesions of low signal intensity on the inversion-recovery image were detected, and we were still able to find high signal areas on spin-echo image. We supposed these might be lesions full of foamy cells, but further investigation is necessary to clarify the meaning of MRI in remission phase. (author)
