Cervical cancer is the third most common gynecological malignancy in Saudi women with an estimated incidence rate of 1.9 cases per 100 000 women-years. More than 40% of cervical cancer cases are diagnosed at advanced stages due to lack of a routine screening program in Saudi Arabia. Thus, national guidelines for routine screening and treatment of precancerous cervical lesions are needed. The Saudi Centre for Evidence-Based Healthcare invited a panel of local experts and partnered them with a team from McMaster University in Canada for methodological support, to develop national clinical practice guidelines on the screening and treatment of precancerous lesions for cervical cancer. After the panel identified key clinical questions, the McMaster University working group updated existing systematic reviews that had been used for the 2013 WHO Guidelines for screening and treatment of precancerous lesions for cervical cancer prevention. Recommendations were based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach. Those recommendations took into account the available evidence, patient values and preferences, and resource use in the Saudi context. The panel provided recommendations on two major issues: screening for precancerous lesions (cervical intraepithelial neoplasia 2 & 3) and treatment of those lesions to prevent cervical cancer in women who tested positive after screening. The Saudi expert panel recommends using the HPV DNA test followed by colposcopy or cytology (Pap test) followed by colposcopy to screen for CIN2+ in women at risk of cervical cancer. The panel recommends cryotherapy or loop excision electrosurgery procedure (LEEP) over cold knife cone biopsy to treat women at risk of cervical cancer that tests positive for CIN2+. Universal screening for precancerous cervical dysplasia in women in Saudi Arabia is recommended using HPV testing and or cytology. Either cryotherapy or LEEP are preferred for treatment. National

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

Introduction Cervical cancer is a malignancy originating in the transformation zone of the cervix, most commonly in the squamous cells. It is the fourth most common cancer in women worldwide, and the third most common cause of female cancer death. Genital human papilloma viruses (HPV) are sexually transmitted and approximately 630 milion people worldwide are infected. More than 200 genotypes, subtypes and variants have been reported, 13-15 being oncogenic type, which could be responsible for cervical intraepithelial lesions (CIN) or cancer. Aim Aim of this study was to evaluate the prevalence of this infection and to identify specific types of human papiloma virus in cervical intraepithelial lesions and cervical cancer in Macedonian women. Material and methods The study was conducted at the University Clinic for Obstetrics and Gynecology, Skopje, Macedonia, in a period of four years. The study was performed on a cohort of 1895, 18 - 73 year old patients who during primary examination had already abnormal PAP smear test. Cervical cells were collected in the lithotomy gynecological position of the patient, using endocervical cytobrush and cotton-tipped swab, and both were placed in sterile test tube with phosphate buffered saline. Samples were stored at temperature of 2 - 8 °C and Human Pappiloma Virus (HPV) genotyping was analyzed within 7 days by multiple Polymerase Chain Reaction (PCR) methods. Results The mean age of enrolled women was 40,8 years±10.36 SD(minimum of 18 and maximum 73 years. Among the patients, the presence of HPV by using PCR was detected in 40,68 % (769 patients) and was highly associated with cervical abnormalities. The prevalence of HPV was highest (82,1%) in women aged 20-years or less and it decreased with age and was lowest (19,9%) among patients older than 50 years. The prevalence of oncogenic types of the virus was higher if the cytologic diagnosis is CIN 3/Carcinoma in situ (CIS). In these patients detection of high risk HPV was in 79

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

To characterize histopathological status, high-risk human papillomavirus (hr-HPV) infection status, and associated risk factors in patients with atypical squamous cells of undetermined significance (ASCUS). Cervical biopsies obtained from 130 ASCUS patients were subjected to histopathological examination and hr-HPV testing. Associations between advanced lesions and hr-HPV load or age were analyzed, and the confounding factors for high-grade cervical lesions were identified. Cervical biopsies from ASCUS patients had a wide range of pathological states, ranging from normal to invasive cervical carcinoma. High-risk HPV infection was significantly associated with advanced cervical lesions in ASCUS patients; hr-HPV infection and the number of gestations were risk factors for developing advanced cervical disease. A significant portion of ASCUS patients harbor advanced cervical lesions. The number of gestations and hr-HPV infection can increase the risk of developing advanced cervical lesions in ASCUS patients.

The high burden of cervical cancer in Zambia prompted the Ministry of Health and partners to develop the cervical cancer prevention program in Zambia (CCPPZ) in 2006. Despite this intervention more women continue to die from the disease and there is little understanding of factors that may be linked with abnormal cervical lesions in the general population. We therefore examined if educational attainment is associated with abnormal cervical lesions among Zambian women aged 15 to 49 years. This study used data from the cervical cancer prevention program in Zambia, where a total of 14,294 women aged 15 to 49 years were screened for cervical cancer at nine health facilities between October 2013 and September 2014. The data represents women from six provinces of Zambia, namely Southern, Central, Copperbelt, Luapula, North-western and Eastern provinces. Step-wise logistic regression analysis using the Statistical Package for the Social Sciences (SPSS) version 21 was used to estimate adjusted odds ratios (AOR) and 95% confidence intervals (CIs) for educational attainment with presence of abnormal cervical lesions as outcome. Multiple imputation was further used to obtain the imputed stabilized estimates for educational attainment. The prevalence of abnormal cervical lesions, using the Visual Inspection with Acetic-acid (VIA) test was 10.7% (n = 1523). Educational attainment was inversely associated with abnormal cervical lesions (AOR = 0.75; 95% CI:0.70-0.81, AOR = 0.74; 95% CI:0.68-0.81 and AOR = 0.46; 95% CI:0.41-0.51) among women with primary, secondary and tertiary education, respectively, compared to those with no formal education. We find reduced likelihood of abnormal cervical lesions in educated women, suggesting a differential imbalance with women who have no formal education. These findings may be a reflection of inequalities associated with access to cervical cancer screening, making the service inadequately accessible for lower educated groups. This

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 prevalence in Rwanda has not been well-described. Visual inspection with acetic acid or Lugol solution has been shown to be effective for cervical cancer screening in low resource settings. The aim of the study is to understand the prevalence and risk factors for cervical cancer and pre- cancerous lesions among Rwandan women between 30 and 50 old undergoing screening. This cross-sectional analytical study was done in 3 districts of Rwanda from October 2010 to June 2013. Women aged 30 to 50 years screened for cervical cancer by trained doctors, nurses and midwives. Prevalence of pre-cancerous and cancerous cervical lesions was determined. Bivariate and multivariate logistic regressions were used to assess risk factors associated with cervical cancer. The prevalence of pre-cancer and invasive cervical cancer was 5.9% (95% CI 4.5, 7.5) and 1.7% (95% CI 0.9, 2.5), respectively. Risk factors associated with cervical cancer in multivariate analysis included initiation of sexual activity at less than 20 years (OR=1.75; 95% CI=(1.01, 3.03); being unmarried (single, divorced and widowed) (OR=3.29; 95% CI=( 1.26, 8.60)); Older age of participants (OR= 0.52; 95% CI= (0.28, 0.97)), older age at the first pregnancy (OR=2.10; 95% CI=(1.20, 3.67) and higher number of children born (OR=0.42; 95%CI =(0.23, 0.76)) were protective. Cervical cancer continues to be a public health problem in Rwanda, but screening using VIA is practical and feasible even in rural settings.

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.

Abfraction is believed to be caused by biomechanical loading forces. It may be due to flexure and ultimate fatigue of tooth tissues that occur away from the point of occlusal loading. Other possible causes of cervical lesions include toothbrush abrasion and erosion. The purpose of this study was to investigate the characteristics and prevalence of abfraction-like lesions in a population of U.S. veterans. The authors evaluated 103 teeth with noncarious cervical lesions in 32 subjects and characterized them based on the surface on which the lesion was located, history of toothbrush abrasion, size of the lesion, presence of plaque, surface texture, and presence and size of occlusal wear facets. Clinical examination revealed that adjacent control teeth had a significantly lower percentage of surfaces with plaque than did teeth with cervical lesions. Control teeth also had significantly less gingival recession than did affected teeth. Seventy-five percent of subjects reported a history of using a firm toothbrush, and 78.1 percent reported using a brushing technique that is known to cause toothbrush abrasion in the affected area. Affected teeth had neither significantly different occlusal wear facets nor occlusal contacts than control teeth. No significant correlations were found between cervical lesion dimensions and facet area. Toothbrush abrasion is strongly suspected as contributing to the formation of the majority of wedge-shaped lesions in this group of subjects. A small subset of lesions is thought to have resulted from some other phenomenon. Although the presence or contribution of occlusal stresses in the direct formation of these lesions could not be measured directly, the possibility of abfraction could not be eliminated. Because the existence of abfraction could not be ruled out in about 15 percent of the cases, teeth with noncarious, wedge-shaped lesions warrant careful occlusal evaluation, with the possible need for occlusal adjustment or bitesplint therapy

Objective To evaluate the diagnostic accuracy of the 2011 International Federation for Cervical Pathology and Colposcopy (IFCPC) colposcopic terminology. Methods The clinicopathological data of 2262 patients who underwent colposcopy from September 2012 to September 2016 were reviewed. The colposcopic findings, colposcopic impression, and cervical histopathology of the patients were analyzed. Correlations between variables were evaluated using cervical histopathology as the gold standard. Results Colposcopic diagnosis matched biopsy histopathology in 1482 patients (65.5%), and the weighted kappa strength of agreement was 0.480 (Pterminology can improve the diagnostic accuracy for all lesion severities. The categorization of major changes and minor changes is appropriate. However, colposcopic diagnosis remains unsatisfactory. Poor reproducibility of type 2 transformation zone and the significance of leukoplakia require further study. PMID:29507681

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

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.

Cervical cancer is the commonest cancer among Indian women. High-risk human papilloma virus (HPV) detection holds the potential to be used as a tool to identify women, at risk of subsequent development of cervical cancer. There is a pressing need to identify prevalence of asymptomatic cervical HPV infection in local population. In our study, we explored the prevalence of HPV genotypes and their distribution in women with cervical lesions. Scrape specimens were obtained from 100 women (study group) with cervical abnormalities. HPV was detected with amplicor HPV tests, and the individual genotypes in these specimens were identified by Hybribio Genoarray test kit. Fifty specimens were also collected from females with healthy cervix (control group). The present study also aimed to determine the status of HPV prevalence and its association with different sociodemographic factors. Out of the total number of 100 samples, 10 (10 %) women tested positive for HPV DNA. Among them, HPV 18 was observed in 6, HPV 16 in 2, HPV 52 and HPV 39 in one each. Fifty specimens collected from patients with healthy cervix were not infected with any of the HPV genotype. Our study generates data of HPV prevalence in patients with cervical lesions visiting tertiary care institute. The data generated will be useful for laying guidelines for mass screening of HPV detection, treatment, and prophylaxis.

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

We describe the technique and the results of the percutaneous aspiration biopsy (PAB) in a series of 9 patients presenting with neck pain and different degrees of myelopathy, in whom the cervical spine X-ray demonstrated lytic lesions of unknown origin. PAB is a useful, relatively safe technique, and leads to histological diagnosis between metastatic and inflammatory processes. Furthermore, in inflammatory lesions with negative hemoculture, PAB may help in detecting the micro-organism responsible and therefore allow a better antibiotic treatment. (orig.).

2010-09-01

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

Objective: To evaluate the clinical value of ultrasonic elastography and ultrasonography comprehensive scoring method in the diagnosis of cervical lesions. Methods: A total of 116 patients were selected from the Department of Gynecology of the first hospital affiliated with Central South University from March 2014 to September 2015.All of the lesions were preoperatively examined by Doppler Ultrasound and elastography.The elasticity score was determined by a 5-point scoring method. Calculation of the strain ratio was based on a comparison of the average strain measured in the lesion with the adjacent tissue of the same depth, size, and shape.All these ultrasonic parameters were quantified, added, and arrived at ultrasonography comprehensive scores.To use surgical pathology as the gold standard, the sensitivity, specificity, accuracy of Doppler Ultrasound, elasticity score and strain ratio methods and ultrasonography comprehensive scoring method were comparatively analyzed. Results: (1) The sensitivity, specificity, and accuracy of Doppler Ultrasound in diagnosing cervical lesions were 82.89% (63/76), 85.0% (34/40), and 83.62% (97/116), respectively.(2) The sensitivity, specificity, and accuracy of the elasticity score method were 77.63% (59/76), 82.5% (33/40), and 79.31% (92/116), respectively; the sensitivity, specificity, and accuracy of the strain ratio measure method were 84.21% (64/76), 87.5% (35/40), and 85.34% (99/116), respectively.(3) The sensitivity, specificity, and accuracy of ultrasonography comprehensive scoring method were 90.79% (69/76), 92.5% (37/40), and 91.38% (106/116), respectively. Conclusion: (1) It was obvious that ultrasonic elastography had certain diagnostic value in cervical lesions. Strain ratio measurement can be more objective than elasticity score method.(2) The combined application of ultrasonography comprehensive scoring method, ultrasonic elastography and conventional sonography was more accurate than single parameter.

To evaluate the short-term consequences and cost-effectiveness associated with the use of novel biomarkers to triage young adult women with minor cervical cytological lesions. Model-based economic evaluation using primary epidemiological data from Norway, supplemented with data from European and American clinical trials. Organised cervical cancer screening in Norway. Women aged 25-33 years with minor cervical cytological lesions detected at their primary screening test. We expanded an existing simulation model to compare 12 triage strategies involving alternative biomarkers (i.e. reflex human papillomavirus (HPV) DNA/mRNA testing, genotyping, and dual staining) with the current Norwegian triage guidelines. The number of high-grade precancers detected and resource use (e.g. monetary costs and colposcopy referrals) for a single screening round (3 years) for each triage strategy. Cost-efficiency, defined as the additional cost per additional precancer detected of each strategy compared with the next most costly strategy. Five strategies were identified as cost-efficient, and are projected to increase the precancer detection rate between 18 and 57%, compared with current guidelines; however, the strategies did not uniformly require additional resources. Strategies involving HPV mRNA testing required fewer resources, whereas HPV DNA-based strategies detected >50% more precancers, but were more costly and required twice as many colposcopy referrals compared with the current guidelines. Strategies involving biomarkers to triage younger women with minor cervical cytological lesions have the potential to detect additional precancers, yet the optimal strategy depends on the resources available as well as decision-makers' and women's acceptance of additional screening procedures. Women with minor cervical lesions may be triaged more accurately and effectively using novel biomarkers. © 2016 Royal College of Obstetricians and Gynaecologists.

To determine the potential clinical utility of tumor markers CEA, TPA, and SCC-Ag for early detection of cervical precancerous lesions. A case-control study was carried out on 120 women (46 patients with histologically confirmed cervical precancerous lesions and 74 healthy controls). The significance of serum selected tumor markers in early detection of cervical intraepithelial neoplasia (CIN) were assessed. Of the case group, the rates of CIN I, II, III, was 69.6%, 23.9%, and 6.5%, respectively. According to the manufacturer's cut-off values of 2 ng/ml, 5 ng/ml, and 70 U/ml for SCC-Ag, CEA and TPA tests, in that order, SCC-Ag test had a sensitivity of 13%, but CEA and TPA tests could not distinguish between case and control groups. The diagnostic sensitivities were highest at cut-off values of 0.55 ng/ml for SCC-Ag, 2.6 ng/ ml for CEA, and 25.5 U/ml for TPA which were 93%, 61%, and 50%, respectively. However, the area under the receiver operating characteristic curve was the largest for SCC-Ag (0.95 vs. 0.61 and 0.60 for CEA and TPA, respectively). Moreover, there was a highly significant direct correlation between SCC-Ag concentration and the degree of cervical precancerous lesions (r=0.847, ptumor marker in Iranian patients with CIN and it needs to be more evaluated by studies with larger populationa.

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 describe the case of a 39-year-old woman with signs and symptoms suggesting cauda equina syndrome. Lumbosacral magnetic resonance imaging (MRI) demonstrated no lesion at this level, while cervical MRI showed a T2-hyperintense lesion in the middle-right anterolateral region of the cervical spinal cord, which may explain the symptoms by involving the anterior spinothalamic tract. We suggest that in cases with cauda equina syndrome presentation and normal lumbosacral MRI, a cervicodorsal lesi...

Cervical cancer represents the second leading cause of malignant neoplasm mortality in women globally. Cervical cytology is the most important screening study. It is therefore of interest to know the prevalence of cytological alterations in the Mexican population. In this study the objective was to calculate the prevalence of intraepithelial lesion in cervical screening cytology. An observational, descriptive and cross-sectional study was developed; the sample was 379 patients from 21 to 64 years of age; we included patients who underwent cervical screening cytology registered in the Detección Oportuna de Cáncer Cervicouterino (DOC-CACU) program database. A descriptive analysis of the data was performed. A prevalence of intraepithelial lesion of 4.49% was found. The 3.17% corresponded to LIEBG and 1.32% to LIEAG. No reports of invasive carcinoma were found. Of these patients, 64.71% corresponded to the age group from 41 to 60 years. 52.94% had had their last cytology in the previous 3 years or more and 35.29% were in postmenopause. A prevalence consistent with what was described in the literature was found. More than half of the affected patients had their last cytology in the previous 3 or more years and corresponded to the age group from 41 to 60 years. A high proportion of patients were in postmenopause.

Background The association of trigeminal neuralgia with pontine lesions has been well documented in multiple sclerosis, and we tested the hypothesis that occipital neuralgia in multiple sclerosis is associated with high cervical spinal cord lesions. Methods We retrospectively reviewed the records of 29 patients diagnosed with both occipital neuralgia and demyelinating disease by a neurologist from January 2001 to December 2014. We collected data on demographics, clinical findings, presence of C2-3 demyelinating lesions, and treatment responses. Results The patients with both occipital neuralgia and multiple sclerosis were typically female (76%) and had a later onset (age > 40) of occipital neuralgia (72%). Eighteen patients (64%) had the presence of C2-3 lesions and the majority had unilateral symptoms (83%) or episodic pain (78%). All patients with documented sensory loss (3/3) had C2-3 lesions. Most patients with progressive multiple sclerosis (6/8) had C2-3 lesions. Of the eight patients with C2-3 lesions and imaging at onset of occipital neuralgia, five (62.5%) had evidence of active demyelination. None of the patients with progressive multiple sclerosis (3/3) responded to occipital nerve blocks or high dose intravenous steroids, whereas all of the other phenotypes with long term follow-up (eight patients) had good responses. Conclusions A cervical spine MRI should be considered in all patients presenting with occipital neuralgia. In patients with multiple sclerosis, clinical features in occipital neuralgia that were predictive of the presence of a C2-3 lesion were unilateral episodic symptoms, sensory loss, later onset of occipital neuralgia, and progressive multiple sclerosis phenotype. Clinical phenotype predicted response to treatment.

Chromosome 3 amplification affecting the 3q26 region is a common genomic alteration in cervical cancer, typically marking the transition of precancerous intraepithelial lesions to an invasive phenotype. Though potential 3q encoded target genes of this amplification have been identified, a functional correlation of potential oncogenic function is still missing. In this study, we investigated copy number changes and the expression level of SEC62 encoded at 3q26.2 as a new potential 3q oncogene in dysplastic cervical lesions and analyzed its role in cervical cancer cell biology. Expression levels of Sec62 and vimentin were analyzed in liquid based cytology specimens from 107 women with varying grades of cervical dysplasia ranging from normal cases to cancer by immunofluorescence cytology. Additionally, a subset of 20 representative cases was used for FISH analyses targeting SEC62. To further explore the functional role of Sec62 in cervical cancer, HeLa cells were transfected with a SEC62 plasmid or SEC62 siRNA and analyzed for their proliferation and migration potential using real-time monitoring and trans-well systems as well as changes in the expression of EMT markers. FISH analyses of the swabbed cells showed a rising number of SEC62 gains and amplifications correlating to the grade of dysplasia with the highest incidence in high grade squamous intraepithelial lesions and squamous cell carcinomas. When analyzing the expression level of Sec62 and vimentin, we found a gradually increasing expression level of both proteins according to the severity of the dysplasia. In functional analyses, SEC62 silencing inhibited and SEC62 overexpression stimulated the migration of HeLa cells with only marginal effects on cell proliferation, the expression level of EMT markers and the cytoskeleton structure. Our study suggests SEC62 as a target gene of 3q26 amplification and a stimulator of cellular migration in dysplastic cervical lesions. Hence, SEC62 could serve as a potential

To explore the value of whole-lesion apparent diffusion coefficient (ADC) histogram and texture analysis in predicting tumor recurrence of advanced cervical cancer treated with concurrent chemo-radiotherapy (CCRT). 36 women with pathologically confirmed advanced cervical squamous carcinomas were enrolled in this prospective study. 3.0 T pelvic MR examinations including diffusion weighted imaging (b = 0, 800 s/mm 2 ) were performed before CCRT (pre-CCRT) and at the end of 2nd week of CCRT (mid-CCRT). ADC histogram and texture features were derived from the whole volume of cervical cancers. With a mean follow-up of 25 months (range, 11 ∼ 43), 10/36 (27.8%) patients ended with recurrence. Pre-CCRT 75th, 90th, correlation, autocorrelation and mid-CCRT ADC mean , 10th, 25th, 50th, 75th, 90th, autocorrelation can effectively differentiate the recurrence from nonrecurrence group with area under the curve ranging from 0.742 to 0.850 (P values range, 0.001 ∼ 0.038). Pre- and mid-treatment whole-lesion ADC histogram and texture analysis hold great potential in predicting tumor recurrence of advanced cervical cancer treated with CCRT.

Full Text Available Aims: We aimed to investigate the immunocytoexpression profiles of a novel assay ProEx C for topoisomerase II alpha (TOP2A and minichromosome maintenance protein 2 (MCM2 in abnormal interpreted smears. Settings and Design: Screening programs with Papanicolaou smear and high risk group human papilloma virus testing have yielded a dramatic reduction of cervical cancer incidence. However, both of these tests have limited specificity for the detection of clinically significant cervical high grade lesions. ProEx C for topoisomerase II alpha (TOP2A and minichromosome maintenance protein 2 (MCM2 has been considered to have tight association with high grade intraepithelial lesions. Materials and Methods: A total number of 54 SurePath cervical cytology specimens of patients previously interpreted as atypical squamous cells-undetermined significance (ASC-US, atypical squamous cells-cannot exclude high grade squamous intraepithelial lesion (ASC-H, low grade squamous intraepithelial lesion (LSIL, and high grade squamous intraepithelial lesion (HSIL were included in our study. Results and Conclusions: ProEx C was positive in 14 of HSILs (100%, 3 of 19 LSILs (16%, 2 of 4 ASC-Hs, and none of ASC-USs (0%. The ProEx C test showed very intense nuclear staining in all cytologically abnormal cells. Further studies are indicated to evaluate the diagnostic role of ProEx C.

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

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

Thyroglobulin in the needle washout (Tg-FNA) and cytology of fine needle aspiration (cyto-FNA) are recommended for diagnosis of metastatic lymphadenopathies and recurrence of differentiated thyroid cancer. The objective of this study was to assess the value of these procedures in 16 cervical masses from patients with thyroid cancer of the follicular epithelium (TC). The study included six patients with TC and cervical lymphadenopathies evaluated before initial thyroid surgery and 10 patients followed up after TC surgery with cervical lumps discovered. FNA was performed in all 16 masses. Results of cyto-FNA, Tg-FNA and of the combined tests were compared to the final diagnosis of each lesion. Among 10 lesions proven to be malignant at surgery, cyto-FNA, Tg-FNA and the combination of both allowed for adequate diagnosis in 7, 9, and 10 cases respectively. Among 6 lesions considered to be benign, cyto-FNA was able to confirm diagnosis in 4, was non-diagnostic in one, and was falsely negative in the remaining case, while Tg-FNA was below the established cut-off value (to consider malignancy) in all cases. In patients with TC and suspect cervical masses, Tg-FNA improved the diagnostic yield of cyto-FNA alone, thus warranting its routine recommendation when FNA is performed. However, universal standardization of the technique and definition of valid cut-off thyroglobulin values (depending on the immunoassay used) above which the lesion should be considered to be malignant are still pending.

Sciatica-like leg pain can be the main presenting symptom in patients with cervical cord compression. It is a false localizing presentation, which may lead to missed or delayed diagnosis, resulting in the wrong plan of management, especially in the presence of concurrent lumbar lesions. Medical history, physical findings and the results of imaging studies were reviewed in two cases of cervical cord compressions, which presented with sciatica-like leg pain. There was multi-level cervical spond...

Full text: Introduction: Characterization of neck lesions is usually not possible without histopathological examination. Objective: To evaluate whether adhesion diffusion coefficient (ADC) values calculated from diffusion weighted magnetic resonance imaging can be used to characterize neck lesions. Material and methods: Diffusion-weighted echo planar MR imaging with b factors of 0, 500 and 1000 sec/mm 2 was prospectively performed with a 1.5 T MR unit in 119 neck lesions in 119 patients. ADC values were measured by 2 radiologists independently on an independent workstation console. Intraclass correlation coefficients were calculated. The mean ADC values were compared using Mann-whitney u test. Results: There was a statistically significant difference between the mean ADC values of benign and malign solid lesions (1.13±0.62 x 10 -3 mm 2 /s and 0.82±0.21 x 10 -3 mm 2 /s respectively). There was no malign lesion with an ADC value more than 1.15 x 10 -3 mm 2 /s. The mean ADC value of malignant lymphomas (0.61±0.14 x 10 -3 ) was significantly smaller than the mean ADC values of other cervical lymphadenopathies. But there was no statistically significant difference between the mean ADC values of reactive, granulomatous and metastatic lymph nodes. Conclusion: ADC values cannot totally distinguish the histopathological subgroups of the neck lesions but shows significant differences between malign and benign lesions.

Although the natural history of cervical and oral human papillomavirus infection has been intensively investigated in the past years, the ability of this virus to infect oral and genital mucosae in the same individual and its potential to co-infect both cervical and oral mucosa are still unclear. The aim of the authors was to assess the presence of oropharyngeal human papillomavirus infection in women with cervical lesions in the South-Eastern Hungarian population. The total of 103 women have been included in the study between March 1, 2013 and January 1, 2015. Brushing was used to collect cells from the oropharyngeal mucosa. Human papillomavirus DNA was detected using polymerase chain reaction, and Amplicor line blot test was used for genotyping. Oropharyngeal human papillomavirus infection was detected in 2 cases (3%). The detected genotypes were 31, 40/61 and 73 in the oropharyngeal region. The results indicate that in women with cervical lesions oropharyngeal human papillomavirus infection rarely occurs.

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

Objective: To study the prevalence of high-risk HPV (HR HPV) in women who accepted cervical cancer screening in Beijing and its distribution in cervical precancerous lesions. Methods: From January 2014 to March 2015, all women aged 35-64 years old and received free screening in institutions of cervical cancer in Beijing were recruited. Stratified cluster random sampling method was used in selecting 31 091 women for gynecological examination and genotyping of HR-HPV. Those positive for HR-HPV (except for HPV 16/18) were examined for cervical cell. For those atypical squamous cells of uncertain significance (ASCUS) and above, who were positive for HPV 16/18 and with uncertain results for cervical cell, were transferred for colposcopy examination. For those with suspicious or abnormal results for colposcopy, were transferred for histopathology. The prevalence of HR-HPV, cervical cancer and precancerous lesions among the participants were analyzed. Results: Totally 31 091 women aged from 35-year-old to 64-year-old, with 44.3% (13 780 women) in the 35-49 age group and 55.7% (17 311 women) in the 50-64 age group. 66.1% (20 536 women) were rural women. The infection rate of HR-HPV was 7.4%(2 305 cases) among the women. High-risk infection rates of HPV except HPV 16/18 were 5.7% (1 758 cases), and multi-infection rate was 1.5% (477 cases). The highest infection rate was 7.9% (1 044 cases) among the 45-49 year-old and 50-54 year-old age groups (χ(2)=14.07, P= 0.015). The rate in rural women was significantly higher than that of the urban women (6.2%, 507 cases; 7.9%, 1 798 cases) (χ(2)=25.75, Page group.

In patients with spinal cord injury after blunt trauma, several studies have observed a correlation between neurologic impairment and radiologic findings. Few studies have been performed to correlate spinal cord injury with ligamentous injury. The purpose of this study was to retrospectively evaluate whether ligamentous injury or disk disruption after spinal cord injury correlates with lesion length. We retrospectively reviewed 108 patients diagnosed with traumatic spinal cord injury after cervical trauma between 1990-2011. Plain films, CT, and MR imaging were performed on patients and then reviewed for this study. MR imaging was performed within 96 hours after cervical trauma for all patients. Data regarding ligamentous injury, disk injury, and the extent of the spinal cord injury were collected from an adequate number of MR images. We evaluated anterior longitudinal ligaments, posterior longitudinal ligaments, and the ligamentum flavum. Length of lesion, disk disruption, and ligamentous injury association, as well as the extent of the spinal cord injury were statistically assessed by means of univariate analysis, with the use of nonparametric tests and multivariate analysis along with linear regression. There were significant differences in lesion length on T2-weighted images for anterior longitudinal ligaments, posterior longitudinal ligaments, and ligamentum flavum in the univariate analysis; however, when this was adjusted by age, level of injury, sex, and disruption of the soft tissue evaluated (disk, anterior longitudinal ligaments, posterior longitudinal ligaments, and ligamentum flavum) in a multivariable analysis, only ligamentum flavum showed a statistically significant association with lesion length. Furthermore, the number of ligaments affected had a positive correlation with the extension of the lesion. In cervical spine trauma, a specific pattern of ligamentous injury correlates with the length of the spinal cord lesion in MR imaging studies

The cervical syndrome refers to a set of disorders caused by the changes in the cervical spine and the soft-tissue surrounding it, with pain as the predominant symptom. Sore neck has been a common problem among a large section of today`s population. The factors contributing to this issue include the modern lifestyle, prolonged sitting and incorrect, fixed or constrained working postures. The root of these difficulties is found in the mechanical disorders of the cervical spine structures, poor body posture and jerky body movements. In the Scandinavian countries neck pain is considered to be a public health problem. The study evaluated 25 patients with an established diagnosis of cervical syndrome. The research was conducted at the PI Institute of Occupational and Sports Medicine of Zenica-Doboj Canton. Each patient received twenty physical therapy treatment sessions. The study included 25 patients suffering from the cervical syndrome. The statistical analysis of gender distribution indicated that 36% of the patients were male, while 64% were female. The mean age of study participants was 46.76±4,23. The patients ranged in age from 39 to 54 years, with no statistically significant difference in the mean age of male and female patients, p=0.691. Analysing the types of occupational activities performed by the patients, the study found a positive relation between neck pain and prolonged sitting at work. The patients who performed office work made up 76% of the total number. Each method of physical therapy applied in the treatment of neck pain patients proved useful. However, the combination of electrotherapy, kinesiotherapy and manual massage proved to be most effective. The cervical syndrome is a common medical condition primarily affecting adult population, with prevalence being higher among women and office workers. The condition places a considerable socioeconomic burden on the afflicted. Cervical pain ranges greatly in severity - from moderate to unbearable, thus

2000-01-01

Full Text Available Eighty-nine patients with lower cervical spine fractures or dislocations were evaluated for risk factors of neurological lesion. The age, sex, level and pattern of fracture and sagittal diameter of the spinal canal were analysed. There were no significant differences on the age, gender, level and Torg's ratio between intact patients and those with nerve root injury, incomplete or complete spinal cord injuries. Bilateral facet dislocations and burst fractures are a significant risk factor of spinal cord injury.

2017-12-29

Objective: Cervical cancer is one of the most common cancers among women all over the world, and main cause is persistent infection with high risk human papillomavirus (HPV) strains. It has been reported that the distribution and prevalence of HPV types varies by geographical region, so that this is important for prevention by type-specific vaccines. The aim of current study was to determine the genotype distribution of HPV using the INNO-LiPA genotyping assay in Zanjan province, North West Iran. Methods: A total of 112 formalin-fixed paraffin embedded (FFPE) tissue samples from cases of low-grade intraepithelial lesion (LSIL), high-grade intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC) were collected. The polymerase chain reaction (PCR) was used to amplify DNA for genotyping. Results: Among the 112 samples from females (ranging from 20 to 69 years, mean age 43.8 ± 10.1) tested for HPV DNA, 50 samples were positive. Based on results of genotyping, most common HPV genotypes were HPV18 (48%) followed by HPV-6 (24%), HPV73 (16%), HPV-51(8%), HPV-31(8%), HPV-16 (8%), HPV-56 (4%), HPV-44 (4%). Conclusion: While HPV infection is the major etiological factor for cervical cancer, presence was relatively low in our survey. In the positive cases, however, HPV18 was the most common in line with many other populations. The fact that types vary among different populations must clearly be taken into account in design of vaccines for our country. Creative Commons Attribution License

Cervical intraepithelial lesions in females attending Women′s Health Clinics in Alexandria, Egypt

2015-01-01

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 Summary: A community-based cross-sectional study was conducted in brothel-based sex workers of West Bengal, Eastern India, to determine their oncogenic human papillomavirus (HPV status and the presence of pre-cancerous lesions. A total of 229 sex workers from three districts of West Bengal participated in the study. All the study participants were interviewed with the aid of a pre-tested questionnaire to determine their sociodemographics, risk behaviour and risk perceptions after obtaining informed verbal consent. The interview was followed by collection of cervical cells from all participants using a disposable vaginal speculum and cervical cytobrush. Oncogenic HPV DNA was detected by real-time polymerase chain reaction (PCR. A simultaneous Papanicolaou test (‘Pap smear’ was performed to detect cervical cytological abnormalities. Overall, the prevalence of oncogenic HPV was found to be 25% (58/229 among the studied population. A subset (n = 112 of the sample was tested separately to determine the existence and magnitude of HPV genotypes 16 and 18. The results showed that genotype 16 was prevalent in 10% (11/112, genotype 18 in 7% (8/112 and both genotype 16 and 18 in 7% (8/112. The HPV prevalence rate showed a decreasing trend with age, being 71.4% in the 10–19 years age group, 32.3% in the 20–29 years age group, 18.3% in the 30–39 years age group and 2.5% in the ≥40 years age group (statistically significant differences, P ≤ 0.00001. Considering the duration of sex work, oncogenic HPV prevalence was found to be 55% (n = 21 and 19% (n = 35 in sex workers with a sex working duration of ≤1 year and >1 year, respectively. This difference was found to be statistically significant both by univariate and multivariate analysis. In this study, it was observed that sex workers with an average number of daily clients of six or more had an HPV prevalence of 67% (n = 6, those with four to five clients had a prevalence of 45% (n

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

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

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

Full Text Available 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.

Although there is a high prevalence of noncarious cervical lesions (NCCLs), the etiology of these lesions remains contentious. To evaluate the combined effects of cyclic fatigue stress and biocorrosion activity on NCCLs. Extracted premolar teeth were allocated into four groups (N = 10). Two groups were cyclically fatigue loaded (100 N; 72 cycles per minute; 9,200 cycles) and placed in either hydrochloric acid gel (pH = 0.1) or orange juice (pH = 4). The other two groups were stored in identical chemical solutions without fatigue load. The buccal-lingual width of each tooth was measured before and after testing. The depth of biocorrosion, normalized by the percentage change in buccolingual width, normalized by time (hour) was calculated. The data were analyzed using a two-way analysis of variance and Tukey's HSD multiple comparison test (α = 0.05). Mean (SD) of the depth of biocorrosion values were as follows: teeth receiving fatigue loading with hydrochloric acid gel exposure (1.003%/hour [0.063]) revealed a significantly higher depth of biocorrosion than the fatigue-loaded group with orange juice exposure (0.511%/hour [0.281]) (p biocorrosion than the group with orange juice (0.009%/hour [0.004]) (p biocorrosion than either group without fatigue loading (p biocorrosion had a significant effect on the depth of the NCCLs. In order to manage the destructive NCCLs lesions properly, it is essential to understand the etiology of these lesions. The present study indicated that the combined mechanisms of cyclic fatigue stress and biocorrosion could contribute to the formation of NCCLs. © 2013 Wiley Periodicals, Inc.

To assess the diagnostic value of cervical cytology and HPV HR DNA testing for the diagnosis of low grade and high-grade squamous intraepithelial lesions across different age groups. The study included 1103 patients, age 25-70 years. All patients underwent in-depth diagnostic tests following either an abnormal Pap test result or a clinically suspicious cervical lesion. In all women the following examinations were performed: a molecular test detecting 14 high-risk types of HPV, a colposcopy examination, as well as directed-biopsy of the cervix. The studied population was subdivided into four age groups. It was observed that the percentage of high grade squamous intraepithelial lesions (HSIL) and cancers increased with women's age. Sensitivity of both methods for detecting high-grade squamous intraepithelial lesions was highest for women aged 40-49 years. Sensitivity values of HPV testing was higher than that of cervical cytology among women under age 50. Specificity of HPV testing increased significantly with age of women and was several fold higher across all age groups than the specificity of cervical cytology.

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.

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

2011-01-01

Background Cervical cancer is a major public health problem worldwide. While Romania has the highest incidence of cervical cancer in Europe, the prevalence of HPV has not been evaluated. We report the first data on HPV prevalence and type distribution in Northeast Romania. Methods HPV prevalence and genotype distribution was investigated in 514 consecutively women with or without cervical lesions in Northeast Romania. Genotyping was performed with Linear Array Genotyping/Roche kit. Results In our study group, 192/514 (37.4%) patients were positive for HPV (infected with single and with multiple HPV types). Most frequent types were: 16 (10.5%), 53 (5.44%), 51 (5.05%), 52 (4.08%) 18 (2.91%) and 31 (2.73%). Conclusions Infection with high risk types of HPV is common in Northeast Romania. Enhanced and systematic screening for cervical cancer is needed. Our results call for the implementation of a National HPV vaccine program in Romania. PMID:22192090

Cervical cancer is an important cause of mortality among women in developing countries, especially in the Latin America and Caribbean (LAC) region. Infection with high-risk (HR) human papillomavirus (HPV) has been identified as the primary cause of cervical cancer. The aim of this study was to determine the frequency of HR-HPV genotypes in low-grade and high-grade squamous intraepithelial lesions (LSIL, HSIL) and cervical carcinoma (CC) among Venezuelan women. Subjects with histopathological diagnosis of LSIL, HSIL, and CC (LSIL=200; HSIL=100; CC=150) were enrolled in the study after obtaining informed consent. Biopsy samples of these subjects were analyzed to determine the lesion type. HPV detection and typing was done using polymerase chain reaction (PCR) and reverse hybridization. HPV type specific prevalence was determined in subjects with single and multiple infections. HPV DNA was detected in 68%, 95%, and 98.7% of LSIL, HSIL, and CC cases, respectively. HR-HPV and low-risk oncogenic HPV (LR-HPV) was observed in 66.9%/11.8% of LSIL cases, 87.3%/3.2% of HSIL cases, and 91.2%/0.7% of CC cases. HPV types -16/-18 (65%) were the most common high-risk HPV types observed, followed by types -52, -33, -45, and -31. Cervical cancer burden in Venezuelan women is substantial. HPV types -16/-18 were the most common types prevalent among Venezuelan women followed by types -52, -33, -45, and -31 (prevalence, ~90.1%). The results of this study provide baseline information on the HPV type distribution, which may facilitate the development of a cervical cancer prevention and control program in Venezuela.

Human papillomavirus (HPV) E2 and L1 proteins are expressed in cervical cells during the lytic stage of infection. Overexpression of p16 INK4A is a biomarker of HPV-associated cervical neoplasia. This study investigated antibodies to HPV16 E2, HPV16 L1, and p16 INK4A in sera from women with no squamous intraepithelial lesion (No-SIL) of the cervix, low-grade SIL, high-grade SIL, and cervical squamous cell carcinoma (SCC). HPV DNA was detected by polymerase chain reaction. Anti-E2, -L1, and -p16 INK4A antibodies in sera were determined by western blot. Among 116 samples, 69 (60%) were HPV DNA-positive. Percentages seropositive for anti-E2, -L1, and -p16 INK4A antibodies were 39.6, 22.4, and 23.3%, respectively. Anti-E2 antibody was significantly correlated with HPV DNA-positive cases. Eighty-seven women (75%) were regarded as infected with HPV, having at least one positive result from HPV DNA, L1, or E2 antibody. Antibody to p16 INK4A was associated with HPV infection (odds = 5.444, 95% CI 1.203-24.629, P = 0.028) and precancerous cervical lesions (odds = 5.132, 95% CI 1.604-16.415, P = 0.006). Interestingly, the concurrent detection of anti-E2 and -p16 INK4A antibodies was significantly associated with HPV infection (odds = 1.382, 95% CI 1.228-1.555, P = 0.044). These antibodies might be good candidate biomarkers for monitoring HPV-associated cervical lesion development to cancer.

Full Text Available It is important to distinguish among squamous intraepithelial lesions (SIL those associated with increased risk cervical cancer. Our aim was to evaluate if the expression level of gen E2 in women with SIL and evidence of viral integration is associated to the grade of lesion. Cervical scrapes HPV16 positive from 19 women with normal histology, 45 women with low-grade SIL (LSIL and 45 women with high-grade SIL (HSIL were analyzed. Real-time PCR was used to quantify the mRNA of E2 and E2 and E6 genes to calculate viral load (E6 and the ratio E2/E6 to assess viral integration. Similar frequencies of E2 expression were found in LSIL and HSIL15/45 (33 %, the frequency in women without SIL was lower 3/19 (15.8 %, and all cases with E2 gene expression had mixed episomal and integrated viral DNA. The viral load increased significantly with the grade of SIL (p= 0.049, while E2/E6 ratio decreased (p=0.049. The ROC analysis showed low capacity of the three viral parameters analyzed to distinguish between low and high grade SIL. In conclusion although SIL with mixed and integrated viral DNA with E2 expression could be at lower risk of progression, and viral load and integration were associated with higher severity of the lesion, its clinical value as biomarkers of HSIL is limited.

Materials and Methods: 85 patients with cytologic and histologic proven cervical carcinoma, HGSIL, LGSIL, ASCUS and 178 patients with totally benign (normal or infecton smear results as a control group who attented to Atatürk Training and Research Hospital 3rd Obstetrics and Gynecology Clinics between the dates of January 2006- July 2008 were included to our study. Within these patients age, first sexual intercourse, age, smoking habit, number of sexual partners, age of menarche and contraception methods were recorded. Pap smears and smears for detection of high risk HPV were taken concurrently from cervical transformation zone and external cervical ostium and the incidence of high risk HPV-DNA were examined. Results: High risk HPV DNA rate was detected as 65.2% positive in cervical carcinoma patients in our study. High risk HPV-DNA was positive in 54.8% of patients with HGSIL while it was positive in 25% of patients with LGSIL. High risk HPV-DNA was positive in 5% of patients with benign cervical cytology results. Discussion: The positivity rates of high risk HPV-DNA results in cervical carcinoma, HGSIL, LGSIL patients and in patients with benign cervical cytologies were statistically significant. When the age of menarche and contraception method were considered the HPV-DNA positivity rates’ differences were statistically insignificant.The differences for the age of first sexual intercourse, number of sexual partners, age and smoking habits were statistically significant.

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

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 lesions were

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.

The objective of this study was to estimate the prevalence of cytological abnormalities of the anal mucosa in women with positive cervical cytology, but without macroscopic anal lesion. Ultimately we postulated if the anal mucosa may be a reservoir of HPV, which would allow the reinfection of cervix. Forty-nine patients with abnormal cervical cytology were selected for this work. In a period not exceeding one week of collecting cervix cytology, two swab specimens of the anal canal were also collected. Women diagnosed with cervical HSIL by Pap smear were referred for colposcopy with biopsy of the lesions, to confirm the cytologic diagnosis and ablation of the lesion. We demonstrated a high prevalence of anal squamous intraepithelial lesions in patients with cervical squamous intraepithelial lesions (29 of the total of 49 patients = 59.2%). Of the 20 cases of cervical LSIL, 11 (55%) had abnormal anal cytology. Of the 26 cases with cervical HSIL, 16 (61.5%) had abnormal anal cytology. So, there was a discrete higher prevalence of abnormal anal cytology in cases of high-grade cervical squamous lesions (cervical HSIL). These results help to support the hypothesis that the anal mucosa is a reservoir of HPV, which can be a source of re-infection for the cervix. However, there was no significant association between the practice of anal sex and the prevalence of anal cytological abnormalities. These facts are epidemiologically important for future programs for population eradication of cervical lesions related to HPV. Diagn. Cytopathol. 2011;39:323-327. © 2010 Wiley-Liss, Inc.

Cervical cancer (CC) is the fourth cause of mortality by neoplasia in women worldwide. The use of immunomarkers is an alternative tool to complement currently used algorithms for detection of cancer, and to improve selection of therapeutic schemes. Aberrant expression of Ezrin and E-cadherin play an important role in tumor invasion. In this study we analyzed Ezrin and E-cadherin expression in liquid-based cervical cytology samples, and evaluated their potential use as prognostic immunomarkers. Immunocytochemical staining of Ezrin and E-cadherin was performed in cervical samples of 125 patients. The cytological or histological diagnostic was performed by Papanicolaou staining or H&E staining, respectively. HPV genotyping was determined using INNO-LIPA Genotyping Extra kit and the HPV physical status by in situ hybridization. Ezrin expression in HaCaT, HeLa and SiHa cell lines was determined by immunocytochemistry, immunofluorescence and Western blot. High Ezrin expression was observed in cervical cancer samples (70%), samples with multiple infection by HR-HPV (43%), and samples with integrated viral genome (47%). High Ezrin expression was associated with degree of SIL, viral genotype and physical status. In contrast, low E-cadherin expression was found in cervical cancer samples (95%), samples with multiple infection by HR-HPV/LR-HPV (87%) and integrated viral genome (72%). Low E-cadherin expression was associated with degree of SIL and viral genotype. Interestingly, Ezrin nuclear staining was associated with degree of SIL and viral genotype. High Ezrin expression, high percent of nuclear Ezrin and low E-cadherin expression behaved as risk factors for progression to HSIL and cervical cancer. Ezrin and E-cadherin expression profile in cervical cytology samples could be a potential prognostic marker, useful for identifying cervical lesions with a high-risk of progression to cervical cancer.

In 386 selective angiograms of cervical vessels fibromuscular dysplasia was revealed in 4 female patients in the age of 30-54 years. FMD was located in the carotid artery (n=5) and in the vertebral artery (n=2) with a total of 8 lesions. 6/8 of the lesions of the seven cervical vessels were located typically in the mid cervical portion of the vessels and 2/6 lesions were located in the atlas loop of the vertebral artery. 4 lesions showed moderate stenosis and 4 vessels showed only mild stenosis. These patterns which demonstrated the typical morphology of fibromuscular dysplasia with alternating irregular zones of widening and narrowing were evaluated well with MR angiography, the others were missed.

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.

The burden of cervical cancer remains huge globally, more so in sub-Saharan Africa. Effectiveness of screening, rates of recurrence following treatment and factors driving these in Africans have not been sufficiently studied. The purpose of this study therefore was to investigate factors associated with recurrence of cervical intraepithelial lesions following thermo-coagulation in HIV-positive and HIV-negative Nigerian women using Visual Inspection with Acetic Acid (VIA) or Lugol's Iodine (VILI) for diagnosis. A retrospective cohort study was conducted, recruiting participants from the cervical cancer "see and treat" program of IHVN. Data from 6 sites collected over a 4-year period was used. Inclusion criteria were: age ≥18 years, baseline HIV status known, VIA or VILI positive and thermo-coagulation done. Logistic regression was performed to examine the proportion of women with recurrence and to examine factors associated with recurrence. Out of 177 women included in study, 67.8 % (120/177) were HIV-positive and 32.2 % (57/177) were HIV-negative. Recurrence occurred in 16.4 % (29/177) of participants; this was 18.3 % (22/120) in HIV-positive women compared to 12.3 % (7/57) in HIV-negative women but this difference was not statistically significant (p-value 0.31). Women aged ≥30 years were much less likely to develop recurrence, adjusted OR = 0.34 (95 % CI = 0.13, 0.92). Among HIV-positive women, CD4 count thermo-coagulation occurs in a significant proportion of women. HIV-positive women with low CD4 counts are at increased risk of recurrent lesions and may be related to immunosuppression.

Stress Analysis of Occlusal Forces in Canine Teeth and Their Role in the Development of Non-Carious Cervical Lesions: Abfraction

2012-01-01

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

Full Text Available Background Dysphagia, is a significant sign of many different lesions in upper digestive system especially in proximal esophagus. Tumors, gastroesophageal reflux, achalasia and extrinsic compressions are the most common causes that may lead to dysphagia in geriatric population. Cervical osteophyte induced dysphagia, is one of the uncommon reasons of dysphagia, therefore other causes of dysphagia must be excluded to establish the exact diagnosis. Eagle syndrome is one of the considerable reason which may lead to misdiagnosis in patients with cervical osteophytes. In this case report, we represent four patients who had dysphagia due to anteriorly located cervical osteophytes and evaluate the patients with special reference to Eagle syndrome. Material and methods After a detailed anamnesis and ENT examination, cervical plain radiographs in four projections and Towne radiographs were obtained for every patient. After that, magnetic resonance imaging (MRI of cervical spine and barium swallowing studies were performed to evaluate the presence of esophageal compression. Results Eagle syndrome was excluded due to absence of other symptoms and physical signs, eventhough unilateral or bilateral elongation of styloid processes was found in all of the patients. Conclusion Cervical osteophytes induced dysphagia is a rare clinical entity, diagnosis should be done by a careful examination, intensive radiologic evaluation. Moreover, all the other causes like Eagle syndrome should be excluded during the diagnosis of cervical osteophyte induced dysphagia.

Hitherto, noncarious cervical lesions (NCCLs) of teeth have been generally ascribed to either toothbrush-dentifrice abrasion or acid "erosion." The last two decades have provided a plethora of new studies concerning such lesions. The most significant studies are reviewed and integrated into a practical approach to the understanding and designation of these lesions. A paradigm shift is suggested regarding use of the term "biocorrosion" to supplant "erosion" as it continues to be misused in the United States and many other countries of the world. Biocorrosion embraces the chemical, biochemical, and electrochemical degradation of tooth substance caused by endogenous and exogenous acids, proteolytic agents, as well as the piezoelectric effects only on dentin. Abfraction, representing the microstructural loss of tooth substance in areas of stress concentration, should not be used to designate all NCCLs because these lesions are commonly multifactorial in origin. Appropriate designation of a particular NCCL depends upon the interplay of the specific combination of three major mechanisms: stress, friction, and biocorrosion, unique to that individual case. Modifying factors, such as saliva, tongue action, and tooth form, composition, microstructure, mobility, and positional prominence are elucidated. By performing a comprehensive medical and dental history, using precise terms and concepts, and utilizing the Revised Schema of Pathodynamic Mechanisms, the dentist may successfully identify and treat the etiology of root surface lesions. Preventive measures may be instituted if the causative factors are detected and their modifying factors are considered. © 2011 Wiley Periodicals, Inc.

This study aimed to provide more information for cancer prevention strategies by determining the distribution of human papilloma virus (HPV) genotype prevalence in invasive cervical carcinoma (ICC) and precancerous lesion patients in the Yangtze River Delta area in China. This multi-centre descriptive cross-sectional study involves four university hospitals in the Jiangzhehu area. Women with histologically confirmed cervical intraepithelial neoplasia (CIN) 1, CIN2, CIN3 or ICC who were diagnosed and treated in the four selected hospitals between February 2012 and April 2014 were eligible for recruitment. The average age of the patients was 40.93 ± 11.87 years old, among whom the youngest was 17 years old and the oldest was 76 years old.Those with immunodeficiency diseases or a previous history of cancer or CIN were excluded. HPV genotyping was performed by a central laboratory. The distribution and age and disease specificity of the HPV genotype prevalence were analysed. Of the 2181 collected samples, 251 were ICC and 1930 were CIN. The mean age of cervical cancer and CIN patients was 40.93 ± 11.8 years (range, 17-76 years). The five most commonly identified HPV types in each lesion class were as follows: CIN1: 52, 58, 16, 33, and CP; CIN2: 16, 58, 52, 33, and 31; CIN3: 16, 58, 33, 52, and 31; and ICC: 16, 58, 18, 52, and 33. CIN1 had an earlier age of onset (30-40 years) than CIN2, CIN3, and cervical cancer. The age of onset of cervical cancer exhibited two peaks at 40-44 and 50-54 years of age. In all infected patients, the frequency of HPV infection with a single type was 62.9%, and with multiple types, it was 38.1%. There was no difference in the frequencies of multiple types amongst the different cervical lesions. The most prevalent genotypes in the investigated area (52, 58, 16 and 18) justify the necessity of anti-HPV vaccination in teenagers and young girls under 24 years old in the Yangtze River Delta area in China.

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.

The aim of the present study was confront the results of the cytological examination with hybrid capture II in the diagnosis of induced cervical intraepithelial lesion-HPV, correlating the cytological findings with biomoleculares. The research was carried through in a group of 160 sexually active women who had espontaneamente looked its gynecologists for consultation of routine, having been submitted to the collection of cervicovaginal material for cytology and for examination of hybrid capture II in the Centro de Patologia Clínica and the Hospital e Maternidade Promater, in the city of the Natal-RN. The results had shown to relatively high numbers of positive cases for HPV using hybrid capture II (41.87%) and the cytology (23.75%). The agreement between the two studied methods relatively was raised (59.38%). It was evident also that the viruses with high oncogênico potential had presented found in the compatible cytology with Lesion of low risk (11.88%), followed of Lesion of high risk (NIC II and III); already the viruses with low oncogênico potential were more associates the Lesion of low risk (6.25%), followed of Lesion of high risk. The cytology, exactly with its limitations, is an important method in the detention of attributable patologias to the HPV, emphasizing that the molecular method comes to complement it and to consolidate the cytological findings.

Extensive gingival recessions associated with cervical abrasions are common among the population. Several different surgical and/or restorative therapies have been proposed to correct these lesions. This manuscript reports the treatment of multiple gingival recessions associated to cervical abrasions. The procedure involved the utilization of subepithelial connective tissue graft (SCTG) combined with coronally advanced flap onto a previously restored root surface. At the postoperative follow-up visits, the success of the restorative/surgical approach was confirmed by the absence of bleeding to probing and periodontal pockets as well as presence of gingival tissue with normal color, texture and contouring. After 18 months of follow-up, the clinical conditions are stable with satisfactory root coverage and periodontal health. An excellent esthetical outcome was achieved and the patient is satisfied with case resolution. PMID:19826605

The association of human papillomavirus (HPV) types to neoplastic lesions increase as a function of their oncogenicity and the duration of the infection since lesion severity progresses from low-grade to high-grade and cancer. In an outbreak, the prevalence of the HPV type involved would increase and the proportion of the associated low-grade lesions would predominate over severe lesions. In this study, the prevalence of HPV types and their association to neoplastic lesions was determined in women subjected to colposcopy in San Luis Potosí, Mexico. DNA from high-risk (HR) and low-risk (LR) HPV types was identified by E6 nested multiplex PCR in cervical scrapes from 700 women with normal cytology, atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesions (LSIL), high-grade squamous intraepithelial lesions (HSIL) or invasive cervical cancer (CC). Overall HPV-DNA prevalence was 67.7 %, that of HR-HPV was 63.1 %, and that of LR-HPV was 21.3 %. The highest prevalence (78.2 %) occurred in the 15-24 year group, whereas that of single infections was 52 % and that of multiple infections (i.e., by 2-6 HPV types) was 48 %. The most prevalent HR types were HPV33 (33.1 %), HPV16 (16.6 %), HPV18 and HPV51 (6.7 % each). HR-HPV prevalence was 29.6 % in normal cytology, 26.7 % in ASCUS, 63.3 % in LSIL, 68.2 % in HSIL, and 90.5 % in CC. Three prevalence trends for HR-HPV types were found in neoplastic lesions of increasing severity: increasing (LSIL  CC) for HPV33. Two-thirds of the women subjected to colposcopy from 2007 to 2010 in San Luis Potosí have HPV infections which predominate in the 15-24 years group. Around half of the infections are by one viral type and the rest by 2-6 types. HPV33 is the most prevalent type, followed by HPV16. Overall HR-HPV prevalence increases with the severity of neoplastic lesions. HPV33 prevalence is highest in LSIL and its U-shaped trend with progressing neoplastic lesions

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

Full Text Available Cervical cancer is not only the most frequently reported cancer among women, but also the most common female genital tract neoplasm in Taiwan. Early detection is effective, because the development, maintenance and progression of precursor lesions (cervical intraepithelial neoplasia [CIN] evolve slowly into invasive cancer, typically over a period of more than 10 years. It is now recognized that human papillomavirus (HPV infection is a necessary cause for over 99% of cervical cancer cases. Advances in the understanding of the causative role of HPV in the etiology of high-grade cervical lesions (CIN 2/3 and cervical cancer have led to the development, evaluation and recommendation of HPV-based technologies for cervical cancer prevention and control. The prevention of HPV infection before the onset of CIN is now possible with recently available prophylactic HPV vaccines, e.g. the quadrivalent Gardasil (Merck & Co., NJ, USA and bivalent Cervarix (GlaxoSmithKline, London, UK. This review article provides an up-to-date summary of recent studies and available information concerning HPV and vaccination in cervical cancer.

Human papillomavirus (HPV) inactivates the retinoblastoma 1 (RB1) gene by promoter methylation and reduces cellular E-cadherin expression by overexpression of DNA methyltransferase 1 (DNMT1). The Epstein-Barr virus (EBV) is an oncogenic virus that may be related to cervical carcinogenesis. In gastric cancer, it has been demonstrated that E-cadherin gene (CDH1) hypermethylation is associated with DNMT1 overexpression by EBV infection. Our aim was to analyze the gene promoter methylation frequency of RB1 and CDH1 and verify the association between that methylation frequency and HPV and EBV infection in cervical lesions. Sixty-five samples were obtained from cervical specimens: 15 normal cervices, 17 low-grade squamous intraepithelial lesions (LSIL), 15 high-grade squamous intraepithelial lesions (HSIL), and 18 cervical cancers. HPV and EBV DNA testing was performed by PCR, and the methylation status was verified by MSP. HPV frequency was associated with cervical cancer cases (p = 0.005) but not EBV frequency (p = 0.732). Viral co-infection showed a statistically significant correlation with cancer (p = 0.027). No viral infection was detected in 33.3% (5/15) of controls. RB1 methylated status was associated with cancer (p = 0.009) and HPV infection (p = 0.042). CDH1 methylation was not associated with cancer (p = 0.181). Controls and LSIL samples did not show simultaneous methylation, while both genes were methylated in 27.8% (5/18) of cancer samples. In the presence of EBV, CDH1 methylation was present in 27.8% (5/18) of cancer samples. Only cancer cases presented RB1 promoter methylation in the presence of HPV and EBV (33.3%). The methylation status of both genes increased with disease progression. With EBV, RB1 methylation was a tumor-associated event because only the cancer group presented methylated RB1 with HPV infection. HPV infection was shown to be significantly correlated with cancer conditions. The global methylation frequency was

Congenital cervical anomalies are essential to consider in the clinical assessment of head and neck masses in children and adults. These lesions can present as palpable cystic masses, infected masses, draining sinuses, or fistulae. Thyroglossal duct cysts are most common, followed by branchial cleft anomalies and dermoid cysts. Other lesions reviewed include median ectopic thyroid, cervical teratomas, and midline cervical clefts. Appropriate diagnosis and management of these lesions requires a thorough understanding of their embryology and anatomy. Correct diagnosis, resolution of infectious issues before definitive therapy, and complete surgical excision are imperative in the prevention of recurrence. Copyright © 2012 Elsevier Inc.

Therapeutic Vaccination for HPV Induced Cervical Cancers

Directory of Open Access Journals (Sweden)

Joeli A. Brinkman

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.

2008-01-01

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.

Full Text Available Non-carious cervical lesions are characterized by structural loss near the cementoenamel junction, without the presence of caries. Anumber of theories have arisen to explain the etiology of such lesions, although the real causes remain obscure, as is reflected by the contradictory terminology used in the literature. In addition to describing acidic and abrasive processes documented as etiological factors, attention is given to the role of mechanical stress from occlusal load, which is the most accepted theory for the development of abfraction lesions. Considering that tensile stress leads to the failure of restorations in the cervical region and that this is a fruitful area for future research, the present study has highlighted diagnosis, prognosis and the criteria for treatment.

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.

Cervical chondrocutaneous branchial remnants are rare and not well known lesions. Histologically the lesion per definition presents as a Choristoma. Choristoma is the pathohistological term for a developmental tumor-like anomaly consisting of tissues foreign to the site at which it is located. Treatment is complete surgical removal as promptly as possible in order to get an exact histopathological diagnosis. A case of a 4-month-old boy with cervical chondrocutaneous branchial remnants anterior to the sternocleidomastoid muscles on both sides is presented. According to literature search this appears to be the second case published on such a bilateral lesion.

Tinnitus can be related to many different aetiologies such as hearing loss or a noise trauma, but it can also be related to the somatosensory system of the cervical spine, called cervicogenic somatic tinnitus (CST). Case studies suggest a positive effect of cervical spine treatment on tinnitus complaints in patients with CST, but no experimental studies are available. To investigate the effect of a multimodal cervical physical therapy treatment on tinnitus complaints in patients with CST. Randomized controlled trial. Patients with a combination of severe subjective tinnitus (Tinnitus Functional Index (TFI): 25-90 points) and neck complaints (Neck Bournemouth Questionnaire (NBQ) > 14 points). All patients received cervical physical therapy for 6 weeks (12 sessions). Patients were randomized in an immediate-start therapy group (n = 19) and a 6-week delayed-start therapy group (n = 19). TFI and NBQ-scores were documented at baseline, after the wait-and-see period in the delayed-start group, after treatment and after 6 weeks follow-up. The Global Perceived Effect (GPE) was documented at all measuring moments, except at baseline. In all patients (n = 38) TFI and NBQ-scores decreased significantly after treatment (p = 0.04 and p tinnitus. This effect was maintained in 24% of patients after follow-up at six weeks. Cervical physical therapy can have a positive effect on subjective tinnitus complaints in patients with a combination of tinnitus and neck complaints. Larger studies, using more responsive outcome measures, are however necessary to prove this effect. NCT02016313. Copyright © 2016 Elsevier Ltd. All rights reserved.

Clinical and pathological heterogeneity of cervical intraepithelial neoplasia grade 3.

Full Text Available Cervical intraepithelial neoplasia grade 3 (CIN3, the immediate cervical cancer precursor, is a target of cervical cancer prevention. However, less than half of CIN3s will progress to cancer. Routine treatment of all CIN3s and the majority of CIN2s may lead to overtreatment of many lesions that would not progress. To improve our understanding of CIN3 natural history, we performed a detailed characterization of CIN3 heterogeneity in a large referral population in the US.We examined 309 CIN3 cases in the SUCCEED, a large population-based study of women with abnormal cervical cancer screening results. Histology information for 12 individual loop electrosurgical excision procedure (LEEP segments was evaluated for each woman. We performed case-case comparisons of CIN3s to analyze determinants of heterogeneity and screening test performance.CIN3 cases varied substantially by size (1-10 LEEP segments and by presentation with concomitant CIN2 and CIN1. All grades of CINs were equally distributed over the cervical surface. In half of the women, CIN3 lesions were found as multiple distinct lesions on the cervix. Women with large and solitary CIN3 lesions were more likely to be older, have longer sexual activity span, and have fewer multiple high risk HPV infections. Screening frequency, but not HPV16 positivity, was an important predictor of CIN3 size. Large CIN3 lesions were also characterized by high-grade clinical test results.We demonstrate substantial heterogeneity in clinical and pathological presentation of CIN3 in a US population. Time since sexual debut and participation in screening were predictors of CIN3 size. We did not observe a preferential site of CIN3 on the cervical surface that could serve as a target for cervical biopsy. Cervical cancer screening procedures were more likely to detect larger CIN3s, suggesting that CIN3s detected by multiple independent diagnostic tests may represent cases with increased risk of invasion.

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

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

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.

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.

To assess the work performance and productivity impact of human papillomavirus (HPV). A cross-sectional study compared 94 employed women with clinically significant HPV-related cervical lesions with 118 healthy controls. Data were collected by self-administered web-based questionnaire. At-work performance limitations and productivity loss (presenteeism) and absenteeism were measured. Univariate and multivariate case-control group and clinical subgroup differences were tested. Based on adjusted mean scores, the HPV group had significantly more at-work limitations and productivity loss than controls (P = 0.009), higher absence rates (P = 0.002), and significantly more productivity loss because of absences (P = 0.007). At-work limitations varied in association with martial status (P = 0.025); at-work productivity loss was associated with years of education (P = 0.039). HPV is costly for working women, their employers, and the economy.

Non-carious cervical lesions (NCCL) are defined as the loss of tooth substance at the cemento-enamel junction and are caused by abrasion, erosion and/or occlusal overload. In this paper we proved that our fast swept source OCT system is a valuable tool to track the evolution of NCCL lesions in time. On several extracted bicuspids, four levels of NCCL were artificially created. After every level of induced lesion, OCT scanning was performed. B scans were acquired and 3D reconstructions were generated. The swept source OCT instrument used in this study has a central wavelength of 1050 nm, a sweeping range of 106 nm (measured at 10 dB), an average output power of 16 mW and a sweeping rate of 100 kHz. A depth resolution determined by the swept source of 12 μm in air was experimentally obtained. NCCL were measured on the B-scans as 2D images and 3D reconstructions (volumes). For quantitative evaluations of volumes, the Image J software was used. By calculating the areas of the amount of lost tissue corresponding to each difference of Bscans, the final volumes of NCCL were obtained. This swept source OCT method allows the dynamic diagnosis of NCCL in time.

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

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.

Pap testing is considered to be the best screening tool for cervical cancer but there is currently great interest in the possible application of human papilloma virus (HPV) testing to supplement Pap screening for cervical cancer. To determine the prevalence of high-risk HPV types in the studied population and to explore the association between high-risk HPV types and cervical dysplasia. Cross-sectional study conducted at the Iasi Cuza Voda Obstetrics-Gynecology Hospital and Suceava County Hospital. 332 women who underwent colposcopy for cervical lesions between 2006 and 2011 were included in this study. The overall prevalence of HPV was 57.23%. HPV prevalence differs significantly in the three age groups up to 50 years. It was highest in patients below the age of 40 and progressively lower with advancing age. The overall prevalence of cervical dysplasia was 56.62%. The prevalence of cervical dysplasia was highest in the age groups up to 40 years. The most important determinant of HPV infection is age. Persistence of HPV appears to be associated with progression to squamous intraepithelial lesion. Dysplasia is often missed in a cervical sample either because of human error in screening and interpretation, or because of suboptimal quality of Pap smear. Incorporation of HPV testing into the present Pap screening program has the potential of making screening for cervical cancer more effective, and a necessary prelude to assessing this is by determining the prevalence of the high-risk types.

To evaluate the clinical performance of Scotchbond Universal (3M Oral Care) and Prime & Bond Elect (Dentsply Sirona) in the restoration of noncarious cervical lesions (NCCLs). This was a randomized controlled clinical trial involving 63 subjects. Two hundred and three NCCLs were restored using Scotchbond Universal and Prime & Bond Elect using both an etch-and-rinse and a self-etch technique. Lesions were notch-shaped NCCLs, and the restorations were placed without any mechanical retention. Restorations were finished immediately after placement and scored with regard to retention, marginal discoloration, marginal adaptation, and secondary caries. Similar assessment of the restorations was performed 18 months after placement. Logistic regression was performed for each outcome separately with a compound symmetric variance-covariance structure assumed to consider a correlation of restorations within subjects. All analyses were conducted using SAS version 9.4 (SAS Inc). One hundred and fifty-eight teeth (77.8% of the restorations placed) in 46 subjects (73% of subjects enrolled) were available for the 18-month follow-up. A statistically significant difference was reached only for the comparison Scotchbond Universal/self-etch (SU_SE) and Prime & Bond Elect/etch-and-rinse (PBE_E&R) groups ( p=0.01), where a restoration with SU_SE was 66% less likely to maintain a score of Alpha for marginal discoloration than a restoration performed with PBE_E&R. Scotchbond Universal and Prime & Bond Elect presented acceptable clinical performance after 18 months of clinical service. However, Scotchbond Universal, when applied with a self-etch approach, did demonstrate a relatively high level of marginal discoloration when compared to the other groups.

'Do not touch' lesions of the skull base

International Nuclear Information System (INIS)

Dobre, Mircea C.; Fischbein, Nancy

2014-01-01

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

An equivalence randomized controlled trial within the subject was organized to evaluate the clinical long-term success of a new 2-step etch & rinse adhesive and a new nano-filled ormocer. 50 subjects, 21 males and 29 females aged between 21 and 65, were randomized to receive 150 restorations, 100 with the new restorative material, 50 with the composite as control, placed in non-carious cervical lesions with the same bonding system. The main outcome measure was the cause of failure at 8 years. Randomization was number table-generated, with allocation concealment by opaque sequentially numbered sealed and stapled envelopes. Subjects, examiner, and analyst were blinded to group assignment. Two interim analyses were performed. Data were analyzed by ANOVA and Cox test (P failures in the experimental group and four failures in the control group. The cumulative loss rate was 7% for both restorative materials, with the annual failure lower than 1%, without any statistically significant difference. There were two key elements of failure: the presence of sclerotic dentin and the relationship between lesion and gingival margin.

Retrospective review. To determine the correlation of Patient-Reported Outcomes Measurement Information System (PROMIS) physical function with Neck Disability Index (NDI) and Modified Japanese Orthopedic Association (mJOA) scores in the surgical cervical myelopathy patient population. Outcome measures such as NDI and mJOA are essential for analyzing treatments for cervical myelopathy. Administrative burdens impose limits on completion of these measures. The PROMIS group developed an outcome measure to improve reporting of patient symptoms and function and to reduce administrative burden. Despite early success, NDI and mJOA have not been compared with PROMIS in patients with cervical myelopathy. This study determines the correlation of NDI and mJOA with PROMIS in surgical patients with cervical myelopathy. A total of 60 patients with cervical myelopathy undergoing surgery were included. PROMIS, NDI, and mJOA were collected preoperatively, and in the first 6 months postoperatively. Correlations between NDI, mJOA, and PROMIS were quantified using Pearson correlation coefficients. Students t tests were used to test significance. All 60 (100%) of patients completed preoperative questionnaires. Fifty-five (92%) of patients completed initial follow-up questionnaires within the first 6 months. PROMIS physical function and NDI demonstrated a strong negative correlation at baseline and in initial follow-up (R = -0.69, -0.76). PROMIS and mJOA demonstrated a strong positive correlation at baseline and in initial follow-up (R = 0.61, 0.72). PROMIS physical function has a strong negative correlation with NDI and a strong positive correlation with mJOA at baseline and in the early postoperative course in patients undergoing surgery for cervical myelopathy. Surgeons may factor these outcomes into the delivery and interpretation of patient-reported outcome measures in this population. Use of PROMIS may improve completion of outcome measures in the office and reduce

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.

Pregnancy and cervical carcinoma occurring concomitantly causes therapeutic and ethical dilemmas. The management for this situation will depend on the gestational age at the time of diagnosis, disease staging, size of the lesion and the patient’s wish to maintain pregnancy and fertility. Review of the literature suggest that pregnancy does not seem to influence the prognosis of cervical cancer. (author)

Identification of high-risk HPV genotypes in patients is essential for vaccination and prevention programs while the geographic distribution of cervical cancer varies widely. HPV 16 is the major cause of cervical cancer followed by HPV 18, HPV 31, HPV 52, or HPV 58 depending on geographic area. In this study, the distribution of HPV genotypes in cervical specimens from women living in Thailand was analyzed by HPV testing with electrochemical DNA chip and PCR direct sequencing. The 716 specimens were grouped according to their cytological grades; 100 normal, 100 low-grade squamous intraepithelial lesions, 100 high grade squamous intraepithelial lesions, and 416 specimens of cervical cancer. The results showed that HPV 16, HPV 18, HPV 52, and HPV 58 are the most common HPV genotypes in Thailand, respectively. With respect to age, women below the age of 26 years were almost negative for high-risk HPV DNA exclusively. Conversely, high prevalence of high-risk HPV DNA and abnormal cytology were usually found in women between 26 and 45 years while cervical cancer was detected mainly in women above the age of 45 years. To increase protection efficiency, a vaccine including HPV 52 and HPV 58 should be offered to Asian women, and primary HPV screening should start at 26-30 years of age. © 2013 Wiley Periodicals, Inc.

The association between some specific human papilloma virus (HPV) types and cervix cancer is well known. However, the genetic conditions that favor the development of cervical cancer are less well known. To determine the presence of satellite instability (MSI) in preneoplastic and neoplastic lesions of the cervix and correlate these findings with HPV genotypes. Biopsy samples of cervical lesions were studied. Sixteen had low grade lesions, 22 had high grade lesions and 28 had an epidermoid cancer. Viral types were identified with polymerase chain reaction, dot-blot hybridization and restriction fragment length polymorphism. MSI was determined using a panel of eight highly informative microsatellites. Microsatellite instability in at least one locus was observed in 91, 56 and 69% of low grade lesions, high grade lesions and epidermoid carcinomas, respectively. MSI-High grade, MSI-Low grade instability and microsatellite stability were observed in 5, 60 and 46% of samples, respectively. Two of three samples with high grade instability had HPV 52 genotype. Other viral subtypes had frequencies that ranged from 78% to 100%, with the exception of HPV16 that was present in only 53% of samples with low grade instability. Two thirds of biopsy samples from cervical lesions had MSI, mechanism that can be involved in the first stages of cervical carcinogenesis. The low frequency of high grade instability, its association with HPV52 and the low frequency of HPV16 in samples with low grade instability, suggest different coadjutant mechanisms in cervical carcinogenesis.

This paper reports on cervical hyperextension injuries that are common and often show minimal radiographic abnormalities, even with severe or unstable lesions. MR images and clinical records of 14 patients scanned within 4 months of hyperextension cervical injuries were reviewed. Clinical, radiographic, and MR findings were correlated. Nine patients had acceleration hyperextension whiplash injuries, four with acute cervical disk herniations developing radiculopathy after several weeks. Five patients injured by direct frontal head trauma presented with myelopathy and had MR evidence of cord injury, and four had acute disk herniation

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.

To examine the relationship between cancer-related fatigue (CRF) and physical activity in daily living in premenopausal disease-free cervical and endometrial cancer survivors. A physical activity monitor was used to collect objective data on daily physical activity. CRF and related variables were measured using self-report scales in a cross-sectional manner. The average age was 44.9 years among 64 women. The higher CRF group comprised 22 women (34%), 10% of whom had severe fatigue. The participants had higher physical activity levels compared with the findings in previous studies, and reported an average of 40 min/day of moderate to vigorous activity. Moderate to vigorous levels of physical activity were derived from essential social activities rather than leisure time exercise. There were no significant differences in physical activity levels between the lower and higher CRF groups. Our study results suggested that the higher level of physical activity in daily living itself had no relationship with decreasing CRF among premenopausal cervical and endometrial cancer survivors. It would be better to focus on cognitive and psychological factors before introducing physical activity programs and be careful of the characteristics of the participants' physical activity among this population in daily basis.

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.

The quadrivalent human papillomavirus vaccine has been provided in Australia through the National Human Papillomavirus Vaccination Program since April 2007. National registry data demonstrates good coverage of the vaccine, with 73% of school-aged girls having received all three doses. To evaluate the effectiveness of the program, we propose a two-pronged approach. In one (sub study A), the prevalence of the vaccine-targeted human papillomavirus genotypes in a population cohort is being estimated, and will be analysed in relation to vaccination status, cervical cytology screening status, demographic, social, behavioural, medical and clinical factors. In sub study B, the distribution of human papillomavirus genotypes detected in high grade cervical intraepithelial neoplastic lesions from vaccine eligible women is being assessed. Sub Study A involves the recruitment of 1569 women aged 18-25, residing in Victoria, Australia, through Facebook advertising. Women who are sexually active are being asked to provide a self-collected vaginal swab, collected at home and posted into the study centre, where human papillomavirus DNA detection and genotyping is performed. Participants also complete an online questionnaire regarding sexual history, experience with, knowledge of, and attitudes towards human papillomavirus, the human papillomavirus vaccine, and cervical screening.Sub Study B will involve the collection of 500 cervical biopsies, positively identified as containing high grade cervical intraepithelial neoplastic lesions and/or adenocarcinoma in situ. Five serial sections are being taken from each case: sections 1 and 5 are being assessed to confirm the presence of the high grade cervical intraepithelial neoplastic lesions or adenocarcinoma in situ; human papillomavirus genotyping is performed on sections 2 and 3; single lesions are excised from section 4 using laser capture microdissection to specifically define causality of a human papillomavirus genotyping of each

Untreated SurePath specimens were tested with the cobas HPV test. PreservCyt specimens were assessed for cytology and tested with AHPV. High-grade cervical intraepithelial neoplasia lesions served as the reference standard. Excellent agreement (95.5%; k=0.91 was observed for ATS-treated SurePath specimens between Tigris and Panther systems and between the PreservCyt and ATS-treated SurePath specimens (91.1%, k=0.81 with the AHPV assay on Tigris. Agreement between the AHPV and cobas assays with SurePath specimens was substantial (89.9%, k=0.80. AHPV sensitivity for CIN2+(n=147 was 91.2% for SurePath and PreservCyt. Cobas HPV sensitivity was 93.9% for SurePath specimens. AHPV testing of SurePath specimens was more specific (59.4% than cobas (54.7% (p<0.001. Detection and genotyping showed similar absolute and relative risks. ATS-treated SurePath specimens tested with AHPV and AHPV-GT assays showed similar performance with greater specificity than cobas HPV on SurePath specimens. Similar overall results were seen using a CIN3 disease endpoint. Keywords: Human papillomavirus, SurePath, PreservCyt, Cervical intraepithelial neoplasia, CIN2+, Aptima transfer solution (ATS

To compare the clearance rate of HPV infection among women aged older than 30 years with biopsy-confirmed cervical low-grade squamous intraepithelial lesions (LSIL) 1 year after cryotherapy with the spontaneous clearance rate (observation). HPV DNA typing by polymerase chain reaction and reverse line blot hybridization were used to identify 14 high-risk types and 23 low-risk types. HPV DNA sequencing was also used for other types. Between December 2007 and March 2009, 100 women were recruited to the study and 60 cases had positive results on HPV testing. Twenty-nine patients were randomly allocated to the cryotherapy group and 31 to the observation group. At 1 year, 89.7% (26/29; 95% CI, 78.6-100%) of the cryotherapy group and 90.3% (28/31; 95% CI, 79.9-100%) of the observation group had negative results on HPV testing (0.6% difference; 95% CI, -15.8 to 14.6%, P=0.94). Cryotherapy failed to increase the clearance of prevalent HPV infections among women with LSIL, although in both arms the clearance rates were above 80%. However, in coupling with visual inspection with acetic acid as a single visit approach, its effect on prevention of HSIL and cervical cancer is still promising. Therefore, cryotherapy should not be withdrawn from such programs. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

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

To estimate efficacy of a visual triage of human papillomavirus (HPV)-positive women to either immediate cryotherapy or referral if not treatable (eg, invasive cancer, large precancers). We evaluated visual triage in the HPV-positive women aged 25 to 55 years from the 10,000-woman Guanacaste Cohort Study (n = 552). Twelve Peruvian midwives and 5 international gynecologists assessed treatability by cryotherapy using digitized high-resolution cervical images taken at enrollment. The reference standard of treatability was determined by 2 lead gynecologists from the entire 7-year follow-up of the women. Women diagnosed with histologic cervical intraepithelial neoplasia grade 2 or worse or 5-year persistence of carcinogenic HPV infection were defined as needing treatment. Midwives and gynecologists judged 30.8% and 41.2% of women not treatable by cryotherapy, respectively (P cryotherapy. The proportion of women judged not treatable by a reviewer varied widely and ranged from 18.6% to 61.1%. Interrater agreement was poor with mean pairwise overall agreement of 71.4% and 66.3% and kappa's of 0.33 and 0.30 for midwives and gynecologists, respectively. In future "screen-and-treat" cervical cancer prevention programs using HPV testing and cryotherapy, practitioners will visually triage HPV-positive women. The suboptimal performance of visual triage suggests that screen-and-treat programs using cryotherapy might be insufficient for treating precancerous lesions. Improved, low-technology triage methods and/or improved safe and low-technology treatment options are needed.

Nuclear magnetic resonance tomography of the cervical canal

Terwey, B.; Koschorek, F.; Jensen, H.P.

1985-12-01

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

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. 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. 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%). This study suggests that buccal HPV16 infection is associated with CIN progression.

The purpose of this study is to determine whether a Stener lesion can be created while testing stability of the ulnar collateral ligament (UCL) of the thumb. Testing was performed in a manner that reproduced clinical examination. Six fresh frozen hand and forearm specimens underwent sequential sectioning of the accessory UCL, the proper UCL, and the ulnar sagittal band. Measurements of radial deviation of the metacarpophalangeal (MCP) joint were taken with the thumb in neutral rotation, pronation and supination, both with 0 degrees and with 30 degrees of flexion of the MCP joint. Visual examination was performed to assess the presence of a Stener lesion. No Stener lesion was created in any position as long as the fascial origin of the ulnar sagittal band at the adductor pollicis longus remained intact. After creating a defect in the ulnar sagittal band, a Stener lesion was created in two specimens, but only when the thumb was flexed and supinated. Pronation provided more stability, and supination provided less stability, with one or both components cut, especially when testing at 30° of flexion. Compared to both components cut without flexion or rotation, there was a statistically significant difference in angulation with the 30 degrees of MCP joint flexion in both neutral rotation in supination. Performing a physical examination to assess the amount of instability of an ulnar collateral ligament injury did not create a Stener lesion if the exam was performed in a controlled, gentle manner with the thumb held without rotation. If the thumb is held in neutral rotation during the exam, an iatrogenic Stener lesion should not be created.

The aim of this study is to determine the impact of visual inspection with acetic acid (VIA) plus immediate cryotherapy on the prevalence of VIA-detected cervical squamous intraepithelial lesion (SIL). Women in four rural communities in Southeast Nigeria were screened with VIA. Women who tested positive to VIA were offered either immediate cryotherapy or large loop excision of the transformation zone based on predetermined eligibility criteria. Cervical biopsies were taken before cryotherapy and examined by consultant histopathologists. All participants were rescreened 1 year later. The main outcome measures were population prevalence of cervical precancers before and after intervention, cure rates, and over-treatment rates. A total of 653 women participated in the study. The prevalence of cervical SIL before the intervention was 8.9% (58/653). The prevalence 1 year later was 1.4% (9/649). This gave an 84.3% reduction in the population prevalence of SIL. The reduction in cervical SIL prevalence was statistically significant (P = 0.0001). The prevalence of high-grade SIL reduced significantly from 4.1% (27/653) preintervention to 0.5% (3/649) 1 year postintervention (P = 0.0001). This gave an 87.8% reduction in the population prevalence of high-grade SIL. Cryotherapy provided a cure rate of 87.9% (95% confidence interval: 76.82-94.33). Population cervical cancer prevention using VIA plus immediate cryotherapy leads to significant reduction in the population prevalence of cervical SIL. This has the potential of being an acceptable supplement to cervical cytology for cervical cancer prevention in low-income populations.

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.

Full Text Available 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.

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

Knowledge of differences in human papillomavirus (HPV)-type prevalence between high-grade cervical intraepithelial neoplasia (HG-CIN) and invasive cervical cancer (ICC) is crucial for understanding the natural history of HPV-infected cervical lesions and the potential impact of HPV vaccination...... on cervical cancer prevention. More than 6,000 women diagnosed with HG-CIN or ICC from 17 European countries were enrolled in two parallel cross-sectional studies (108288/108290). Centralised histopathology review and standardised HPV-DNA typing were applied to formalin-fixed paraffin-embedded cervical...... higher in ICC than in HG-CIN. The difference in age at diagnosis between CIN3 and squamous cervical cancer for HPV18 (9 years) was significantly less compared to HPV31/33/'other' (23/20/17 years), and for HPV45 (1 year) than HPV16/31/33/'other' (15/23/20/17 years).

Full Text Available While the mortality rates for cervical cancer have been drastically reduced after the introduction of the Pap smear test, it still is one of the leading causes of death in women worldwide. Additionally, studies that appropriately evaluate the risk of developing cervical lesions are needed. Therefore, we investigated whether intracellular signaling entropy, which is measured with microarray data, could be useful for predicting the risks of developing cervical lesions. We used three datasets, GSE63514 (histology, GSE27678 (cytology and GSE75132 (cytology, a prospective study. From the data in GSE63514, the entropy rate was significantly increased with disease progression (normal < cervical intraepithelial neoplasia, CIN < cancer (Kruskal-Wallis test, p < 0.0001. From the data in GSE27678, similar results (normal < low-grade squamous intraepithelial lesions, LSILs < high-grade squamous intraepithelial lesions, HSILs ≤ cancer were obtained (Kruskal-Wallis test, p < 0.001. From the data in GSE75132, the entropy rate tended to be higher in the HPV-persistent groups than the HPV-negative group. The group that was destined to progress to CIN 3 or higher had a tendency to have a higher entropy rate than the HPV16-positive without progression group. In conclusion, signaling entropy was suggested to be different for different lesion statuses and could be a useful biomarker for predicting the development of cervical intraepithelial neoplasia.

Full Text Available 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.

Full Text Available Handedness is one of the most recognized lateralized behavior in humans. Usually, it is associated with manual superiority regarding performance proficiency. For instance, more than 90% of the human population is considered more skilled with the right hand, which is controlled by the left hemisphere, than with the left. However, during the performance of bimanual tasks, the two hands usually assume asymmetric roles, with one hand acting on objects while the other provides support, stabilizing the object. Traditionally, the role of the two hands is viewed as fixed. However, several studies support an alternate view with flexible assignments for the two hands depending on the task. The supporting role of the hand depends on a closed loop pathway based on proprioceptive inputs from the periphery. The circuit’s efferent arm courses through the dorsal corticospinal tract (dCST in rodents and terminate on spinal cord interneurons which modulate the excitability of motoneurons in the ventral horn. In the present work, we developed an experimental model of unilateral lesion targeting the cervical dCST with microinjections of the vasoconstrictor endothelin-1 (ET-1 to evaluate the degree of flexibility of forelimb assignment during a food manipulation task. Our results show that just 3 days after unilateral corticospinal tract (CST injury in the cervical region, rats display severe motor impairment of the ipsilateral forepaw together with a remarkable reversal of motor assignment between the forelimbs.

Is screen-and-treat approach suited for screening and management of precancerous cervical lesions in Sub-Saharan Africa?

Science.gov (United States)

Fokom-Domgue, Joël; Vassilakos, Pierre; Petignat, Patrick

2014-08-01

The World Health Organization guidelines for screening and management of cervical precancerous lesions updated in 2013 made an emphasis on the use of the 'screen-and-treat' approach for cervical cancer prevention. In order to facilitate scaling-up in low income settings, most of these screen-and-treat strategies do not involve confirmatory biopsy. This yields a certain rate of overtreatment. In other words, a majority of people undergoing screen-and-treat intervention who are treated does not necessarily benefit from the treatment. Therefore, the issue of potential short term and long term complications of the recommended treatment procedures (cryotherapy and Loop Electrosurgical Excision Procedure) arises. This question has seldom been studied in resource poor countries, particularly in Sub-Saharan Africa where Human Immunodeficiency Virus infection is rampant in an epidemic fashion and where the procreative capacities are socially rewarding for women. We draw the attention of the scientific community and policy makers to the fact that the lack of evidence supporting the safety of these treatment procedures in African populations may have an impact on the acceptability of these strategies and therefore on the effectiveness of screening programs.

Full Text Available Objective: To study the effect of hrHPV infection on anti-apoptotic gene and pro-apoptotic gene expression in cervical cancer tissue. Methods: A total of 56 patients with cervical cancer, 94 cases of patients with cervical intraepithelial neoplasia and 48 cases of patients with chronic cervicitis who were treated in our hospital from May 2013 to December 2015 were selected for study and included in malignant group, precancerous lesion group and benign group respectively. hrHPV infection as well as the expression of anti-apoptotic genes and proapoptotic genes in cervical tissue were detected. Results: hrHPV infection rate and viral load in cervical tissue of malignant group were significantly higher than those of precancerous lesion group and benign group; P27 and p16 levels in cervical tissue of malignant group were significantly lower than those of precancerous lesion group and benign group, and K-ras, c-myc, Prdx4 and TNFAIP8 levels were significantly higher than those of precancerous lesion group and benign group; the greater the HPV virus load, the lower the p27 and p16 levels and the higher the K-ras, c-myc, Prdx4 and TNFAIP8 levels in cervical tissue. Conclusions: hrHPV infection can result in tumor suppressor genes p27 and p16 expression deletion and increase the expression of proto-oncogene and apoptosis-inhibiting genes, and it is associated with the occurrence and development of cervical cancer.

Full Text Available Background and objectives:Cervical cancer due to Human papillomavirus (HPV is one of the leading causes of morbidity and mortality in women. Testing of HPV can identify women who are at risk of cervical cancer. Nowadays, molecular methods like real time polymerase chain reaction (PCR and hybrid capture technique are applied for detecting HPV in cervical specimens. The objective of the present study was to determine the rate of HPV infection in women with chronic cervicitis and cervical intraepithelial neoplasia (CIN by a commercial real time polymerase chain reaction test kit and by a hybrid capture HPV DNA test. Methods:Women aged between 20 to 55 years with chronic cervicitis and CIN were enrolled in the study after obtaining informed consent. Cervical specimen was collected by using cervical brush and stored in transport medium until used. HPV was detected by High Risk Screen Real-TM Quant 2x (Sacace, Biotechnologies SrI, Italy real time PCR kit (HR RT-PCR and by Hybrid Capture-2 High-Risk HPV DNA (Hc-2; Digene Corporation, USA test. Results: Total 72 women with chronic cervicitis and CIN of different grades were included in the study. Out of this, HPV infection detected by HR RT-PCR was 31 (43% and by Hc-2 was 14 (19.4%. Both the tests were able to detect HPV infection in all the CIN 3 cases and in most of the CIN 2 cases. However, HR RT-PCR detected higher number of HPV in chronic cervicitis and CIN1 cases. Conclusion:The study has shown that HR RT-PCR and Hc-2 tests are equally effective in detecting HPV infection in patients with CIN 2 and CIN 3 lesions. However, HR RT-PCR is more sensitive test for detecting HPV in chronic cervicitis and early CIN lesions and, therefore can be used in epidemiological study to detect presence of HPV in general population.

Full Text Available Abstract Background There is scant information on whether Human Immunodeficiency Virus (HIV seropositivity has an influence on the outcome of treatment of precancerous cervical lesions using cryotherapy. We studied the prevalence of cervical abnormalities detectable by visual inspection and cervical lesions diagnosed by colposcopy according to HIV serostatus and described the outcomes of cryotherapy treatment. Methods Trained nurses examined women not previously screened for cervical cancer using visual inspection with acetic acid (VIA and Lugol's iodine (VILI in two family planning/post natal clinics in Kampala, Uganda, from February 2007 to August 2008. Women with abnormal visual inspection findings were referred for colposcopic evaluation and HIV testing. Women with precancerous cervical lesions detected at colposcopy were treated mainly by cryotherapy, and were evaluated for treatment outcome after 3 months by a second colposcopy. Results Of the 5 105 women screened, 834 presented a positive screening test and were referred for colposcopy. Of these 625 (75% returned for the colposcopic evaluation and were tested for HIV. For the 608 (97.5% women in the age range 20-60 years, colposcopy revealed 169 women with cervical lesions: 128 had inflammation, 19 had low grade squamous intraepithelial lesion (LGSIL, 13 had high grade squamous intraepithelial lesion (HGSIL, 9 had invasive cervical cancer and 2 had inconclusive findings. Detection rates per 1 000 women screened were higher among the older women (41-60 years compared to women aged 20-40 years. They were accordingly 55% and 20% for inflammation, 10% and 2% for LGSIL, 5% and 2% for HGSIL, 6% and 1% for invasive cervical cancer. Of the 608 women, 103 (16% were HIV positive. HIV positivity was associated with higher likelihood of inflammation (RR = 1.7; 95% CI: 1.2-2.4. Conclusions Detection rates were higher among older women 41-60 years.

In the cervical disc disease, computed tomography (CT) myelographic and conventional myelographic findings were surgically confirmed. The authors classified the disc protrusion into two types, and demonstrated the characteristic features of these two types in CT myelography and conventional myelography. Moreover, the correlation with the localization of the disc protrusion and the laterality of the myelopathy are discussed. All cases were obtained using a late generation scanner and the patient in the supine position with the neck in the neutral position. Using conventional myelography, all examinations were obtained with the neck in a flexion, neutral and extended positions. Twenty-two patients with cervical disc disease operated on by an anterior approach were studied by CT myelography and conventional myelography. According to the style of the compression on the spinal cord, the cervical disc protrusion was classified into two main groups, the subligamentous type and epiligamentous type. This study included 10 patients of the subligamentous type and 12 patients of the epiligamentous type. The localization of the disc protrusion and the laterality of the myelopathy often corresponded with each other. Not only the localization of the lesion, but also the pincer effect, especially the oblique pincer effect, which is reinforced by dynamic factors, are important in the understanding of the manifestations of myelopathy. In the subligamentous type, the main cause of the myelopathy is considered to be the mechanical pressure by the prolapsed nucleus pulposus. In the epiligamentous type, on the other hand, it is believed to be the pincer effect, reinforced by dynamic factors. (author)

Objectives To estimate efficacy of a visual triage of human papillomavirus (HPV)– positive women to either immediate cryotherapy or referral if not treatable (eg, invasive cancer, large precancers). Methods We evaluated visual triage in the HPV-positive women aged 25 to 55 years from the 10,000-woman Guanacaste Cohort Study (n = 552). Twelve Peruvian midwives and 5 international gynecologists assessed treatability by cryotherapy using digitized high-resolution cervical images taken at enrollment. The reference standard of treatability was determined by 2 lead gynecologists from the entire 7-year follow-up of the women. Women diagnosed with histologic cervical intraepithelial neoplasia grade 2 or worse or 5-year persistence of carcinogenic HPV infection were defined as needing treatment. Results Midwives and gynecologists judged 30.8% and 41.2% of women not treatable by cryotherapy, respectively (P cryotherapy. The proportion of women judged not treatable by a reviewer varied widely and ranged from 18.6%to 61.1%. Interrater agreement was poor with mean pairwise overall agreement of 71.4% and 66.3% and κ ’s of 0.33 and 0.30 for midwives and gynecologists, respectively. Conclusions In future “screen-and-treat” cervical cancer prevention programs using HPV testing and cryotherapy, practitioners will visually triage HPV-positive women. The suboptimal performance of visual triage suggests that screen-and-treat programs using cryotherapy might be insufficient for treating precancerous lesions. Improved, low-technology triage methods and/or improved safe and low-technology treatment options are needed. PMID:19509579

The purpose of this investigation was to establish a baseline of physical therapist education on temporomandibular disorders (TMD)-related topics during credentialed orthopedic manual physical therapy fellowship training and compare it to cervical spine disorders education. An online survey was distributed electronically to each fellowship program credentialed by the American Physical Therapy Association (APTA) and recognized by the Academy of Orthopedic Manual Physical Therapists (AAOMPT). Data were analyzed to compare overall exposure to TMD educational content, including a direct comparison of TMD and cervical spine disorders education. The response rate was 79%. Thirteen programs (87%) reported providing both didactic and clinical training on both TMD and cervical spine disorders. Didactic education for cervical spine disorders ranged from 16-20 hours to over 25 hours, whereas TMD hours ranged from 0 to 6-10 hours. Clinical education for cervical spine disorders ranged from 11-15 hours to over 25 hours, whereas TMD hours ranged from 0 to 6-10 hours. The number of hours of exposure during didactic training and the number of patients exposed to during clinical training were significantly different when comparing TMD to cervical spine disorders exposure (P<0.0001). The data indicate a lack of uniformity between credentialed fellowship programs in orthopedic manual physical therapy with respect to the extent to which programs expose trainees to evaluation and management of TMD. There is consistency in that all programs provided more training on cervical spine disorders than TMD. Despite a high level of clinical specialization, fellows-in-training receive minimal TMD education.

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.)

Purpose  Shoulder pain and disability pose a diagnostic challenge owing to the numerous etiologies and the potential for multiple disorders to exist simultaneously. The evidence to support the use of clinical tests for superior labral anterior to posterior complex (SLAP) is weak or absent. The purpose of this study is to determine the diagnostic validity of physical examination maneuvers for SLAP lesions by performing a methodologically rigorous, clinically applicable study. Methods  We recruited consecutive new shoulder patients reporting pain and/or disability. The physician took a history and indicated their certainty about each possible diagnosis ("certain the diagnosis is absent/present," or "uncertain requires further testing"). The clinician performed the physical tests for diagnoses where uncertainty remained. Magnetic resonance imaging arthrogram and arthroscopic examination were the gold standards. We calculated sensitivity, specificity, and likelihood ratios (LRs) and investigated whether combinations of the top tests provided stronger predictions. Results  Ninety-three patients underwent physical examination for SLAP lesions. When using the presence of a SLAP lesion (Types I-V) as disease positive, none of the tests was sensitive (10.3-33.3) although they were moderately specific (61.3-92.6). When disease positive was defined as repaired SLAP lesion (including biceps tenodesis or tenotomy), the sensitivity (10.5-38.7) and specificity (70.6-93.8) of tests improved although not by a substantial amount. None of the tests was found to be clinically useful for predicting repairable SLAP lesions with all LRs close to one. The compression rotation test had the best LR for both definitions of disease (SLAP tear present = 1.8 and SLAP repaired = 1.67). There was no optimal combination of tests for diagnosing repairable SLAP lesions, with at least two tests positive providing the best combination of measurement properties (sensitivity 46.1% and

This prospective study was approved by the institutional review board, and written informed consent was obtained. Seventy-three patients with cervical cancer (33-69 years old; 35 patients with International Federation of Gynecology and Obstetrics stage IB cervical cancer) and 38 patients (38-61 years old) with normal cervix or cervical benign lesions (control group) were enrolled. All patients underwent 3-T diffusion-weighted imaging (DWI) with b values of 0 and 800 s/mm(2). ADC values of the entire tumor in the patient group and the whole cervix volume in the control group were assessed. Mean ADC, median ADC, 25th and 75th percentiles of ADC, skewness, and kurtosis were calculated. Histogram parameters were compared between different pathologic features, as well as between stage IB cervical cancer and control groups. Mean ADC, median ADC, and 25th percentile of ADC were significantly higher for adenocarcinoma (p = 0.021, 0.006, and 0.004, respectively), and skewness was significantly higher for squamous cell carcinoma (p = 0.011). Median ADC was statistically significantly higher for well or moderately differentiated tumors (p = 0.044), and skewness was statistically significantly higher for poorly differentiated tumors (p = 0.004). No statistically significant difference of ADC histogram was observed between lymphovascular space invasion subgroups. All histogram parameters differed significantly between stage IB cervical cancer and control groups (p histogram analysis may help to distinguish early-stage cervical cancer from normal cervix or cervical benign lesions and may be useful for evaluating the different pathologic features of cervical cancer.

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.

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.)

Brain metastasis from uterine cervical cancer is rare, with an incidence of 0.5%, and usually occurs late in the course of the disease. We report a case of uterine cervical cancer with brain metastasis as the initial site of presentation. A 50-year-old woman with headache, vertigo, amnesia and loss of appetite was admitted for persistent vomiting. Contrast enhanced computed tomography showed a solitary right frontal cerebral lesion with ring enhancement and uterine cervical tumor. She was diagnosed with uterine cervical squamous cell carcinoma with parametrium invasion and no other distant affected organs were detected. The cerebral lesion was surgically removed and pathologically proved to be metastasis of uterine cervical squamous cell carcinoma. The patient underwent concurrent chemoradiotherapy, followed by cerebral radiation therapy, but multiple metastases to the liver and lung developed and the patient died 7 months after diagnosis of brain metastasis. © 2015 The Authors.

Until now, serum tumor markers, physical examination, and conventional imaging modalities, such as CT of MRI, have been used in assessment of recurrence of cervical cancer after treatment. However, CT and MRI provide only anatomical data, which makes analysis of post treatment change difficult. This study aims to explore the effectiveness of PET/CT, a new scanning device that combines PET and CT, in evaluation of cervical cancer lesions in patients with suspected recurrence. We studied 51 patients suspected of recurrence among those who underwent F 18 FDG PET/CT for cervical cancer follow up at Gachon University Gil Hospital between June 2006 and August 2009. Patients were considered to be at risk for recurrence if they reported symptoms that were clinically suggestive of recurrence, or if physical examination showed abnormalities, serum tumor marker levels rose, or follow up images revealed changes, such as new lesions or swelling of previous sites. Sensitivity, accuracy, specificity, and positive and negative predictive values of PET/CT were measured. A total of 37 patients were confirmed with recurrence or metastasis, 13 of whom were diagnosed histologically. Measured across all patients, PET/CT scored 97.3% on sensitivity, 71.4% on specificity, a positive predictive value of 90%, a negative predictive value of 90.9%, and an accuracy of 90.2%. PET/CT yielded only one false negative diagnosis and four false positives. As F 18 FDG PET/CT has high sensitivity and negative predictive value in diagnosis of recurrent cervical cancers, it is expected that it will be useful for clinical determination of recurrence and prevention of unnecessary additional treatments. The hope is that a future study on a larger scale will contribute further to determination of the efficacy of PET/CT

We evaluated the feasibility of “screen and treat approach” for cervical cancer prevention and the performance of different screening tests among FSWs.Methods: Women were screened using cytology, VIA (visual inspection with acetic acid, and VILI (visual inspection with Lugol’s iodine and underwent colposcopy, biopsy, and immediate treatment using cold coagulation, if indicated, at the same visit.Results: We screened 300 FSWs of whom 200 (66.67% were HIV uninfected and 100 (33.34% were HIV infected. The overall prevalence of CIN 2–3 lesions was 4.7%. But all women with CIN 2–3 lesions were HIV infected, and thus the prevalence of CIN 2–3 lesions in HIV-infected FSWs was 14/100 (14%, 95% confidence interval: 7.2–20.8. All of them screened positive by all three screening tests. Cold coagulation was well tolerated, with no appreciable side effects.Conclusion: Cervical cancer prevention by “screen and treat” approach using VIA, followed by ablative treatment, in this high-risk group of women is feasible and can be implemented through various targeted intervention programs.

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.

Cervical cerclage aims to strengthen not only the mechanical properties of the cervix, but also its immunological and anti-infectious functions. The demonstration of a strong interrelation between cervical insufficiency as well as decreased cervical length at endo-vaginal ultrasonography and infection has changed the indications cerclage. Actually we can distinguish three indications for cerclage: prophylactic, for obstetrical history; therapeutic, for shortened cervical length at ultrasonography in patients at risk and; emergency cerclage in case of threatening cervix at physical examination. The McDonald's technique is the most recommended. In case of failure, it is proposed to realize cerclage at a higher level on the cervix either by vaginal or abdominal route.

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

Themba G Ginindza

Full Text Available Human papillomavirus (HPV has proven to be the cause of several severe clinical conditions on the cervix, vulva, vagina, anus, oropharynx and penis. Several studies have assessed the costs of cervical lesions, cervical cancer (CC, and genital warts. However, few have been done in Africa and none in Swaziland. Cost analysis is critical in providing useful information for economic evaluations to guide policymakers concerned with the allocation of resources in order to reduce the disease burden.A prevalence-based cost of illness (COI methodology was used to investigate the economic burden of HPV-related diseases. We used a top-down approach for the cost associated with hospital care and a bottom-up approach to estimate the cost associated with outpatient and primary care. The current study was conducted from a provider perspective since the state bears the majority of the costs of screening and treatment in Swaziland. All identifiable direct medical costs were considered for cervical lesions, cervical cancer and genital warts, which were primary diagnoses during 2015. A mix of bottom up micro-costing ingredients approach and top-down approaches was used to collect data on costs. All costs were computed at the price level of 2015 and converted to dollars ($.The total annual estimated direct medical cost associated with screening, managing and treating cervical lesions, CC and genital warts in Swaziland was $16 million. The largest cost in the analysis was estimated for treatment of high-grade cervical lesions and cervical cancer representing 80% of the total cost ($12.6 million. Costs for screening only represented 5% of the total cost ($0.9 million. Treatment of genital warts represented 6% of the total cost ($1million.According to the cost estimations in this study, the economic burden of HPV-related cervical diseases and genital warts represents a major public health issue in Swaziland.

Multiple-integrations of HPV16 genome and altered transcription of viral oncogenes and cellular genes are associated with the development of cervical cancer.

Directory of Open Access Journals (Sweden)

Xulian Lu

Full Text Available The constitutive expression of the high-risk HPV E6 and E7 viral oncogenes is the major cause of cervical cancer. To comprehensively explore the composition of HPV16 early transcripts and their genomic annotation, cervical squamous epithelial tissues from 40 HPV16-infected patients were collected for analysis of papillomavirus oncogene transcripts (APOT. We observed different transcription patterns of HPV16 oncogenes in progression of cervical lesions to cervical cancer and identified one novel transcript. Multiple-integration events in the tissues of cervical carcinoma (CxCa are significantly more often than those of low-grade squamous intraepithelial lesions (LSIL and high-grade squamous intraepithelial lesions (HSIL. Moreover, most cellular genes within or near these integration sites are cancer-associated genes. Taken together, this study suggests that the multiple-integrations of HPV genome during persistent viral infection, which thereby alters the expression patterns of viral oncogenes and integration-related cellular genes, play a crucial role in progression of cervical lesions to cervix cancer.

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.

Trichomonas vaginitis (TV) infection has obviously been implicated in gynecological morbidity but still unclear in cervical lesions. To evaluate the risk of hr-HPV infection and cervical intraepithelial neoplasia grade 2 or worse (CIN2 + ) by TV infection. The pooled study was conducted among 12 population-based, cervical cancer screening studies throughout China (N = 24,054). HPV was detected by Hybrid Capture ® 2 (HC2) test. Past TV infection was measured by self-reporting, current TV infection was diagnosed by liquid-based cytology (LBC), cervical lesions was diagnosed by histopathology. Respective prevalence of hr-HPV and CIN2+ were 17.4% and 3.3%. Out of 24,054 women, 14.6% reported past TV infection, and out of 11,853 women, 9.9% had current TV infection. Current TV-positive women had an increased risk for hr-HPV (OR 1.31, 95%CI: 1.11-1.56). The risk of CIN2+ decreased for hr-HPV positive women with current TV infection (adjusted OR 0.50, 95% CI: 0.30-0.84) and past TV infection (adjusted OR 0.68, 95% CI: 0.54-0.86). Among hr-HPV negative women, no significant associations were observed between past or current TV infection and risk of CIN2+. Women infected with HPV are more likely to be infected by other types of sexually transmitted diseases. Current TV-positive women had an increased risk for hr-HPV infection compared to currently TV-negative women. Both past and current TV-positive women had a decreased risk for CIN2+, especially among high-risk HPV positive women. More direct investigation into the interaction between TV, HPV, inflammatory signals, and risk of carcinogenesis are further needed. Copyright © 2017. Published by Elsevier B.V.

Full Text Available BACKGROUND Neoplastic lesions of uterine cervix is one of the most common malignant neoplasms in women. The tremendous success in giving a confirmed diagnosis of the disease by doing histopathological examination is of prime importance in giving the most appropriate treatment and to understand the prognosis. The aim of the study is to study the incidence and age-wise distribution of the neoplastic lesions of the uterine cervix in peri and postmenopausal women by doing histopathological examination of neoplastic lesions and by doing correlation of clinical findings with histopathological examination. MATERIALS AND METHODS The study included 803 cases of total cervical specimens, out of which 180 cases of neoplastic cervical lesions were found, out of which 150 cases were found in the peri and postmenopausal age groups, i.e. above 40 years of age. The study was done in Gauhati Medical College and Hospital, Guwahati, from the period 1 st June, 2013, to 1 st June, 2014. The specimens that were included in the study were punch biopsies, hysterectomies and polypectomies and cervical specimens were studied by doing histopathological examinations. RESULTS Out of the 150 cases of neoplastic lesions in the peri and postmenopausal women, the most common neoplastic lesion was cervical intraepithelial neoplasia, i.e. CIN (8.3% of the cervix, followed by malignant (5.6% and benign (4.7% lesions of the cervix in this study group of patients. CONCLUSION Histopathological examination of the cervix is an effective method of giving a confirmed diagnosis of all the noncancerous, precancerous and cancerous lesions of uterine cervix, which helps in giving the most appropriate treatment and also helps in understanding the prognosis.

Full Text Available Background: Cervical carcinoma is a common cause of death in India. It is presented by spectrum of precancerous lesions, called cervical intraepithelial neoplasia (CIN. Cervical cytological screening is designed to detect over 90% of cytological abnormalities. It has been established that cervical cancers can be diagnosed at the pre-invasive stage with adequate, repetitive cytological screening. Keeping in view of the importance of cervical PAP abnormalities & by classifying them by Bethesda terminology; correlation with clinical findings & histopathological findings was done. Methods: All cervical Pap smears reported in Department of Pathology from 1st August 2015 to 31st July 2016, were prospectively studied and classified according to revised Bethesda terminology, 2014. Also cytoradiological and clinico-cytological, cytohistological correlation was studied. Results: Due to increasing awareness among masses inculcated by social workers, most of the patients for PAP smear cytology came for routine screening to rule out cervical lesions followed by clinical finding of per-vaginal discharge. The 350 screened patients were in the third and fourth decades of life. 99/350 cases were subjected to USG study, with maximum number of cases (34 cases showing normal study, followed by cases with ovarian cysts and fatty liver disease. Negative for intra-epithelial lesion (NILM without any denotable organism was the pre-dominant cytological finding of PAP smear study followed by cases of NILM with bacterial vaginosis (30 cases with two malignancies. Intra-epithelial lesions (IELs were noted in 16.86%. ASCUS comprised 12.29%, ASC-H comprised 1.14%, L-SIL comprised 1.71%, HSIL comprised 1.43%, Atrophic cervical smears comprised 5.14%, Squamous cell carcinoma comprised 0.29% cases. ASC/LSIL ratio was 7.8 and inadequacy rate for PAP smear study was 7.43%. Cytologyhistopathology correlation was possible in 62 cases. Conclusion: Classification of cervical PAP

Cervical spinal cord injuries in patients with cervical spondylosis.

Regenbogen, V S; Rogers, L F; Atlas, S W; Kim, K S

1986-02-01

Eighty-eight patients over age 40 with traumatic cervical spinal cord injuries were clinically and radiographically evaluated, and comparison was made with 35 spinal cord injury patients under age 36. While most older patients sustained obvious bony and/or ligamentous damage commensurate with their neurologic findings, 25 (28%) of the 88 patients had no demonstrable bony abnormalities and 17 (20%) of the 88 patients had only minimal evidence of bony injury. Of particular interest are the patients with severe cord injuries, yet no bony abnormalities, who seem to form a distinct subgroup of the cervical spinal cord injury patient on the basis of radiographic and clinical features. Of these 25 patients, 24 (96%) had severe cervical spondylosis. Fourteen (56%) of the 25 patients were injured in falls, five (36%) of these 14 being of a seemingly trivial nature. Of the 42 patients with minimal or no demonstrable bony abnormalities, 33 (79%) were evaluated with plain tomography and no occult fractures or other significant pathology was demonstrated. Pantopaque myelography in 27 (64%) of the 42 cases revealed no extruded disk or other surgical lesion in any patient. In large measure, these injuries can be attributed to cervical spondylosis, which narrows the canal and makes the cord more susceptible to compression by the bulging ligamenta flava during hyperextension.

High HPV-51 prevalence in invasive cervical cancers: results of a pre-immunization survey in North Sardinia, Italy.

Directory of Open Access Journals (Sweden)

Andrea Piana

Full Text Available BACKGROUND: Human Papilloma virus (HPV is recognized as the etiological agent of benign and malignant ano-genital lesions. The most prevalent genotypes associated with cervical carcinoma are HPV-16 and -18 worldwide. However, recent studies have emphasized the role of other genotypes, such as HPV-51, in the pathogenesis of cervical dysplasia. The aim of the study was to estimate the burden of HPV-51 infection in invasive cervical malignant lesions in Northern Sardinia, Italy. METHODS/PRINCIPAL FINDINGS: An observational, retrospective, prevalence, mono-center study was carried out to evaluate the presence of HPV genotypes in tissues biopsies of cervical lesions (CIN-1, CIN-2, CIN-3 and invasive carcinoma gathered from 1996 to 2009. Biological samples were collected from women admitted consecutively to a tertiary university hospital situated in Sassari, Italy. Molecular methods were used to identify 28 oncogenic HPV types. A total of 155 formalin-fixed and paraffin-embedded cervical tissue samples were analyzed. Approximately half of the cervical lesions were classified as invasive carcinoma. HPV-DNA was detected in 71% of the samples, with a higher frequency (100% in those categorized as invasive neoplasia. Mono- or co-infections were demonstrated in 45.8% and 25.8% of the cervical samples, respectively. Overall, the most prevalent HPV types were -16 (49% and -51 (19.4%, with an increased frequency of detection associated with the severity of the cervical lesions. CONCLUSIONS/SIGNIFICANCE: This survey highlights for the first time the relevant role of HPV-51 infection in the pathogenesis of invasive cervical cancer prior to the introduction of a vaccination program. Although a selection bias could have influenced the results, other recent studies have described the impact of HPV-51. This remarkable epidemiological element should be carefully evaluated, particularly in the view of opting for preventive vaccines, whose cross-protection patterns

Most non-screen-detected cervical cancers are advanced stage. We assess the potential for cytology to expedite diagnosis when used outside of routine call and recall screening for cervical cancer. Two cohorts of women with cytology that did not appear to have been taken as part of routine screening, nested within a census of cervical cytology, in England between April 2007 and March 2010 were studied: 93,322 women aged 40-69 at first cytology, and 14,668 women aged ≥70. The diagnostic performance of high grade cervical squamous intraepithelial lesion (HSIL) or worse cytology was estimated. We also estimated case-fatality from stage distribution in women aged ≥66 with and without cytology in the year prior to diagnosis. There were 259 cancers diagnosed in women aged 40-69 at first cytology, and 78 in women aged ≥70. The sensitivity of cytology ≥ HSIL for cancer was 89% and 83% respectively, and the number of women needed to test to identify one cancer was 404 (95% confidence interval [CI]: 355-462) and 226 (95% CI: 177-292) respectively. Women aged ≥66 with cytology within a year of diagnosis had earlier stage cancers than those without, corresponding to a 17-22% reduction in case fatality. Cervical cytology is an excellent identifier of cancer among women tested outside routine screening call and recall. Its use as a triage tool, for instance in women with vague gynaecological symptoms, could facilitate earlier stage diagnosis and reduce cervical cancer mortality. © The Author(s) 2015.

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

Full Text Available Introduction: Since the pioneering days of the anterior cervical approach introduced by Cloward et al. in the early 1950s, anterior cervical discectomy and fusion (ACDF has been the standard procedure for most discogenic and degenerative cervical spinal lesions. Although traditional interbody fusion using iliac bone can maintain the patency of the neuroforamen and ensure solid fusion, selection of patients, and of surgical procedure for ACDF is a continuous challenge. Aim: The aim of this study was to assess the results of cervical discectomy and fusion with cervical cages in treatment of cervical radiculopathy clinically and radiologically. Materials and Methods: Eighteen patients suffering from cervical radiculopathy were operated upon using this technique. They were 15 males and 3 females. Clinical and radiological assessment, visual analog scale (VAS for neck and arm and modified Oswestery neck disability index (NDI were done preoperatively and at 4 weeks, 3, 6, and 12 months postoperatively. Polyetheretherketone (Peek cages filled with iliac bone graft were used after cervical discectomy. The levels operated upon were C 5-6 in 16 patients and C4-5 in 2 patients. Results: Marked clinical improvement as regard arm and neck pain, and NDI was observed. The pre and post operative mean and standard deviations (SD of the various scores were as follows. VAS for pain in arm reduced from mean of 8 (SD 1.76 to mean 0.4 (SD 0.4, VAS for neck pain reduced from mean of 3.5 (SD 1.58 to mean of 0.8 (SD 0.47, and NDI from mean of 20.2 (SD 0.89 to 2.1(SD 1.05. Fusion occurred in all patients. Subjectively 79% of the patients reported marked improvement in neck pain, and 95% reported marked reduction in arm pain. Conclusion: Anterior cervical discectomy and cage fusion resulted in high fusion rate with minimal preservation of lordosis.

Non-carious cervical lesions (NCCLs) are often encountered in clinical practice and their aetiology attributed to toothbrush abrasion, erosion and tooth flexure. This paper aims to determine the prevalence and severity of NCCLs in a sample of patients attending a university clinic in Trinidad and to investigate the relationship with medical and dental histories, oral hygiene practices, dietary habits and occlusion. Data were collected via a questionnaire and clinical examination. Odds ratios were used to determine the association of the presence of lesions and the factors examined. One hundred and fifty-six patients with a mean age of 40.6 years were examined of whom 62.2% had one or more NCCLs. Forty five per cent of the lesions were sensitive to compressed air. Younger age groups had a significantly lower correlation with the presence of NCCLs than older age groups. Other significant factors included patients who reported heartburn, gastric reflux, headaches, bruxism, sensitive teeth and swimming or had a history of broken restorations in the last year. There was also significant correlation of NCCLs in patients who brushed more than once a day or used a medium or hard toothbrush. Patients with vegetarian diets and those who reported consuming citrus fruits, soft drinks, alcohol, yoghurt and vitamin C drinks were associated with the presence of lesions. Significant associations were also found in patients with group function, faceting, clicking joints or those who wore occlusal splints.

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

To evaluate the clinical significance of atypical squamous cells of undetermined significance (ASCUS) in PAP test in post-menopausal women and compare with reproductive age women. A total of 367 patients who referred to our gynecologic oncology clinic were included to the study between September 2012 and August 2013. Data for 164 post-menopausal (group 1) and 203 pre-menopausal (group 2) women with ASCUS cytology were evaluated retrospectively. Immediate colposcopy and endocervical curettage was performed for both groups and conization for all women with a result suggestive of CIN2-3. Histopathological results and demographic features of patients were compared between the two groups. Mean age of the patients was 54.6±6.5 years in group 1 and 38±6.6 years in group 2. Some 14 (8.5%) of post- menopausal women and 36 (17.7%) of pre-menopausal women were current smokers (p=011). Totals of 38 (23.2%) post-menopausal and 64 (31.5%) pre-menopausal women were assessed for HPV-DNA. High risk HPV was detected in 7 (4.3%) and 21 (10.3%), respectively (p=0.029). Final histopathological results recorded were normal cervix, low grade cervical intra-epithelial neoplasia (CIN 1), and high grade cervical intra-epithelial neoplasia (CIN2-3). In group 1 results were 84.8%, 12.2% and 1.8%, respectively, and in group 2 were 71.9%, 23.2% and 4.9%. There were no cases of micro invasive or invasive cervical carcinoma in either group. Two cases were detected as endometrial carcinoma in the menopausal group (1.2%). In current study we found that preinvasive lesions were statistically significantly higher in pre-menopausal women than post- menopausal women with ASCUS. Cervicitis was more common in menopausal women. Therefore, we think that in case of ASCUS in a post-menopausal woman there is no need for radical management.

Occipital neuralgia is a common form of headache that is characterized by paroxysmal severe lancinating pain in the occipital nerve distribution. The exact pathophysiology is still not fully understood and occipital neuralgia often develops spontaneously. There are no specific guidelines for evaluation of patients with occipital neuralgia. Cervical spine, spinal cord and posterior neck muscle lesions can induce occipital neuralgia. Brain and spine imaging may be necessary in some cases, according to the nature of the headache or response to treatment. We report a case of cervical myelitis presenting as occipital neuralgia.

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.

Cervical cancer remains the most common malignancy in women living in low- and middle-income countries, despite the decline of the disease in countries where cervical cytology screening programs have been implemented. To review the current incidence of cervical cancer in low-resource countries, the availability and types of screening programs, and the treatment options. Literature review through PubMed, Internet search, and personal communication. Although data are incomplete, available figures confirm that the rate of cervical cancer deaths and the availability of cervical cancer screening programs are inversely proportional and vary, in general, by the wealth of the nation. Despite the success of cervical cytology screening, many major health care organizations have abandoned screening by cytology in favor of direct visualization methods with immediate treatment of lesions by cryotherapy provided by trained, nonmedical personnel.

Objective: The purpose of this study was to evaluate the clinical value of 18 F-fluorode-oxyglucose (FDG) PET/CT for staging and re-staging cervical cancer cases. Methods: This retrospective study included 88 patients. Of the 88 patients, 19 were primary cervical cancer, 11 were benign cervical tumor and 58 were cervical cancer patients with post-treatment surveillance. All had either whole body or abdominal-pelvic FDG PET/CT imaging. The diagnosis was established according to the pathologic results of surgery or biopsy, and(or) multi-modality imaging and clinical follow-up for at least six months. Results: For initial diagnosis of cervical cancer, the sensitivity, specificity and accuracy of FDG PET/CT were 17/19 (89.5%), 10/11 (90.9%) and 27/30(90.0%) respectively. For re-staging cervical cancer, the sensitivity, specificity and accuracy of FDG PET/CT were 10/11 (90. 9%), 47/47 (100. 0%) and 57/58 (98.3%) respectively. In all, 41 had metastases. The sensitivity, specificity and accuracy of FDG PET/ CT detecting metastases were 92.7%, 88.9% and 90.9% respectively. Of the metastatic sites, 66.3% were abdominal-pelvic lymph nodes, 26.8% of the metastatic lymph nodes were detected with diameters less than 1.0 cm. Twenty-two of twenty seven (28.6%) patients were identified to have extra-pelvic lesions after PET/CT and were then changed their treatment plans. Conclusions: 18 F-FDG PET/CT is useful in staging and re-staging cervical cancer patients. PET/CT is of great value in identifying small lesions and also in detecting extra-pelvic lesions. (authors)

Full Text Available OBJECTIVES To know the incidence and aetiological factors of cervical lymphadenopathy. To know the most common group of lymph nodes enlarged. To assess the response to management. MATERIALS AND METHODS This study includes 50 patients who attended the Surgical OPD, studied taking detailed clinical history, after physical examination and arriving at clinical diagnosis, confirmation was done by FNAC and biopsy. RESULTS Tuberculous lymphadenopathy is the commonest cause of cervical lymphadenopathy with 68% followed by chronic nonspecific lymphadenopathy with 32%. There was no case of sarcoidosis in this series. Disease commonly affected the 2 nd and 3 rd decades with 19% and 18% respectively. There is comparatively an increased incidence of tuberculous cervical lymphadenopathy in females than males. The average age of presentation was 30.5 years. There was no definite history of contact with tuberculosis in 82% of cases. In this study series, 44% of the patients belonged to the low income group, 46% belonged to the middle income group. There was only unilateral involvement of node in 72% of cases right side was affected in 32% and left side was affected in 40% of cases. Bilateral involvement was seen in 14% of the cases. The lymph nodes were associated with other groups of lymph nodes in 10% of cases. Chest radiography findings showed the evidence of coexisting active tuberculosis lesions in 8 out of 50 cases (16% and normal was 42(84%. CONCLUSION Knowledge about clinico-demographic perspectives of cervical lymphadenopathy in respect to their cytopathological diagnosis will help to detect/refer the respective cases early for investigations and treatment. Surgical intervention is definitely required in many cases, though most of the cases are medically curable.

The clinically validated high-risk human papillomavirus (hrHPV) Hybrid Capture 2 (HC2) and GP5+/6+-PCR assays were analyzed on an Indicating FTA Elute cartridge (FTA cartridge). The FTA cartridge is a solid dry carrier that allows safe transport of cervical samples. FTA cartridge samples were compared with liquid-based samples for hrHPV and high-grade cervical intraepithelial neoplasia (CIN) detection. One cervical sample was collected in a liquid-based medium, and one was applied to the FTA cartridge. DNA was eluted directly from the FTA cartridge by a simple elution step. HC2 and GP5+/6+-PCR assays were performed on both the liquid-based and the FTA-eluted DNA of 88 women. Overall agreement between FTA and liquid-based samples for the presence of hrHPV was 90.9% with GP5+/6+-PCR and 77.3% with HC2. The sensitivity for high-grade CIN of hrHPV testing on the FTA cartridges was 84.6% with GP5+/6+-PCR and only 53.8% with HC2. By comparison, these sensitivities on liquid-based samples were 92.3% and 100% for GP5+/6+-PCR and HC2, respectively. Therefore, the FTA cartridge shows reasonably good overall agreement for hrHPV detection with liquid-based media when using GP5+/6+-PCR but not HC2 testing. Even with GP5+/6+-PCR, the FTA cartridge is not yet capable of detecting all high-grade CIN lesions.

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

Reduce morbidity and death rates of women with cervical cancer in Guinea. This was a five-day cross-sectional study carried out in two successive years (2012 and 2013) at the CERFFO-PCG in Conakry. The target population was women aged 25-49. Approximately 500 women for 2012 and 900 women were expected in these cervical screening campaigns by visual methods (IVA and IVL) with immediate treatment of precancerous lesions. After histologic confirmation of the cancer lesions, the management was carried out according to the protocols in force in the country. We performed a simple descriptive analysis and the results expressed as a percentage and on average. The target population represented 60.4% in 2012 and 76.2% in 2013, of the total number of women received. The incidence rate of high-grade intraepithelial lesions and cancers increased from 2.6% in 2012 to 0.9% in 2013. In 2012, the 57 precancerous lesions were treated with immediate treatment and 10 cases of cancers out of the 16 had a surgical treatment. Also in 2013, all precancerous lesions were treated immediately and 2 cancers out of the 4 benefited from surgery. Our research shows that, with creativity, flexibility, good organization and efficient use of resources, morbidity and death rates of women with cervical cancer in a very resources can be significantly reduced.

Cervical cancer remains a major health problem, especially in developing countries. Colposcopic examination is used to detect high-grade lesions in patients with a history of abnormal pap smears. New technologies are needed to improve the sensitivity and specificity of this technique. We propose to test the potential of fluorescence confocal microscopy to identify high-grade lesions. We examined the quantification of ex vivo confocal fluorescence microscopy to differentiate among normal cervical tissue, low-grade Cervical Intraepithelial Neoplasia (CIN), and high-grade CIN. We sought to (1) quantify nuclear morphology and tissue architecture features by analyzing images of cervical biopsies; and (2) determine the accuracy of high-grade CIN detection via confocal microscopy relative to the accuracy of detection by colposcopic impression. Forty-six biopsies obtained from colposcopically normal and abnormal cervical sites were evaluated. Confocal images were acquired at different depths from the epithelial surface and histological images were analyzed using in-house software. The features calculated from the confocal images compared well with those features obtained from the histological images and histopathological reviews of the specimens (obtained by a gynecologic pathologist). The correlations between two of these features (the nuclear-cytoplasmic ratio and the average of three nearest Delaunay-neighbors distance) and the grade of dysplasia were higher than that of colposcopic impression. The sensitivity of detecting high-grade dysplasia by analysing images collected at the surface of the epithelium, and at 15 and 30 μm below the epithelial surface were respectively 100, 100, and 92 %. Quantitative analysis of confocal fluorescence images showed its capacity for discriminating high-grade CIN lesions vs. low-grade CIN lesions and normal tissues, at different depth of imaging. This approach could be used to help clinicians identify high-grade CIN in clinical

Cervical Microbiome and Cytokine Profile at Various Stages of Cervical Cancer: A Pilot Study.

Directory of Open Access Journals (Sweden)

Astride Audirac-Chalifour

Full Text Available 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.

In primary studies with 3 T Magnets, phase sensitive reconstruction of T1-weighted inversion recovery (PSIR) have showed ability to depict the cervical multiple sclerosis (MS) lesions some of which may not be detected by short tau inversion recovery (STIR). Regarding to more availability of 1.5 T MRI, this study was designed to evaluate the eligibility of PSIR in 1.5 T for detection of spinal cord MS lesions. In a study between September 2016 till March 2017 the patients with proven diagnosis of MS enrolled to the study. The standard protocol (sagittal STIR and T2W FSE and axial T2W FSE) as well as sagittal PSIR sequences were performed using a 1.5 T magnet. The images were studied and the lesions were localized and recorded as sharp or faint on each sequence. Of 25 patients (22 females and 3 males, with mean age of 33.5 ± 9.8 years and mean disease duration of 5.4 ± 3.9 years) 69 lesions in STIR, 53 lesions in T2W FSE, 47 lesions in Magnitude reconstruction of PSIR (Magnitude), and 30 lesions in phase sensitive (real) reconstruction PSIR were detected. A Wilcoxon signed-rank test showed STIR has a statistically significant higher detection rate of the plaques rather than other three sequences. (STIR and T2W FSE, Z = -4.000, p definition of the plaques rather than other three sequences. This study shows that in the setting of a 1.5 T magnet field, STIR significantly has a superiority over both of the PSIR reconstructions (i.e. real and magnitude) for the detection as well as the boundary definition of the cervical cord lesions of MS. These results have a good relevance to clinical practice by using MRI scanners and sequences routinely available, however, it is discrepant with other reports performed by 3 T Magnet fields.

In order to observe the radiobiological characteristics of cervical cancer, the author carried out irradiation of 60 Co in 16 cases of cervical cancer. The primary lesion of each case was exposed to radiation of 100 R once a day, 40 times in sequence, totaling 4,000 R. To evaluate this results, the vaginal smears were obtained everyday and examined for changes in cancerous cells caused by the irradiation. The results of our study showed that cervical cancer could be classified into three groups according to the radiosensitivity of its cancerous cells. In the group of low-radiosensitivity (11 cases of 16), the cancerous cells decreased gradually, and enlargement of the nuclei of the cancerous cells was observed from 2,000 R of irradiation, but the majority of the cancerous cells were those of nucleus after the irradiation of 4,000 R. In all of the 5 uterus removed, residual cancer lesion was noted. The radiocuability was unfavourable. In the group of high-radiosensitivity (4 cases of 16), the cancerous cells decreased remarkablly. Enlargement of nucleus was noted from 1,000 R of the irradiation, the cancerous cells of small-sized nucleus appeared with the irradiation of 3,000 R but the cancerous cells almost disappeared with the irradiation of 4,000 R. The radiocuability was favourable. In the group of combination of high-radiosensitivity and low-radiosensitivity portions (one case of 16), the cancerous cells decreased remarkablly until the exposure to the radiation of 2,000 R but thereafter did slowly. In a removed uterus, the cancer lesion was noted, but the prognosis was favourable. The foregoing results suggest that changes in the nuclear diameter of the cancerous cells in vaginal smears during irradiation can tell the radiosensitivity of the cancerous cells. (Kanao, N.)

The aim of this study was to compare the performance of multimodal hyperspectral spectroscopy (MHS), which combines fluorescence and reflectance spectroscopy, with that of conventional laboratory-based screening tests, such as the Papanicolaou (Pap) smear test and human papilloma virus (HPV) DNA test, for detecting precancerous lesions of the cervix. The study utilized a cross-sectional design, and the kappa test was used in the analytical assessment. MHS scans were obtained from a sample of 70 consecutive patients, followed by sample collection for Pap and HPV DNA analysis and colposcopy referral, if indicated. Of the 70 patients evaluated, the results of cervical spectroscopy were normal in 38 (54.3%) patients, and they were abnormal in 32 (45.7%) patients. Based on the cytology results, 45 (64.3%) samples were normal, and 25 (35.7%) samples were abnormal. According to the results of the HPV DNA test, 47 (67.14%) samples were normal, and 17 (24.28%) samples were abnormal. Based on the results of the kappa test, the agreement between MHS and cytology was 0.793 (p < 0.001). The agreement between MHS and the HPV DNA test was 0.195 (p = 0.086), and the agreement between MHS and colposcopy was 0.479 (p < 0.001).

This study aims to evaluate and to compare the performance of cervical digital photography (CDP) to the visual inspection with acetic acid (VIA) and visual inspection with Lugol's iodine (VILI) methods for screening the uterine cervix cancer and its precursor lesions in developing countries. A cross-sectional study was performed in Brazil. 176 women were evaluated by VIA, VILI, CDP with acetic acid and CDP with Lugol's iodine. Kappa statistic was used to estimate the interobserver and intermethod agreement. Sensitivity, specificity and diagnostic accuracy of the four methods (VIA, VILI, CDP with acetic acid, CDP with Lugol's iodine) was calculated. Interobserver agreement for CDP with acetic acid was K = 0.441 and for CDP with Lugol's iodine was K = 0.533; intermethod agreement of VIA and CDP with acetic acid, K = 0.559; and of VILI and CDP with Lugol's iodine, K = 0.507. Sensitivity and specificity of CDP with acetic acid were 84.00 and 95.83 %, and of CDP with Lugol's iodine were 88.00 and 97.26 %, respectively. The diagnostic accuracy of CDP with acetic acid and CDP with Lugol's iodine was 92.78 and 94.90 %, respectively. This was the first study to assess the CDP with Lugol's iodine performance, which had similar performance to the CDP with acetic acid. CDP is considered a promising method for screening the uterine cervix cancer and its precursor lesions in developing countries.

The change in transcription pattern induced by post-transcriptional RNA splicing is an important mechanism in the regulation of the early gene expression of human papilloma virus (HPV). The present study was conducted to establish a method to specifically amplify HPV-16 E6-associated transcripts. The E6-related transcripts from 63 HPV-16-positive cervical tumor tissue samples were amplified, consisting of eight cases of low-risk intraepithelial lesions, 38 cases of high-risk intraepithelial lesions and 17 cases of cervical cancer (CxCa). The appropriate amplified segments were recovered following agarose gel electrophoresis, and subjected to further sequencing and sequence alignment analysis. Six groups of E6 transcription patterns were identified from HPV-16-positive cervical tumor tissue, including five newly-discovered transcripts. Different HPV-16 E6-associated transcription patterns were detected during the development of CxCa. Over the course of the progression of the low-grade squamous intraepithelial lesions to CxCa, the specific HPV-16 E6-associated transcription patterns and the dominant transcripts were all different. As indicated by this study, the transcription pattern of the E6 early gene of HPV-16 was closely associated with the stages of cervical carcinogenesis, and may also be involved in the development of CxCa.

More information is needed about time between sexual initiation and human papillomavirus (HPV) infection and development of cervical precancer. The objectives were to investigate the time between first sexual activity and detection of first cervical HPV infection or development of first cervical intraepithelial neoplasia (CIN), and associated factors in women from the double-blind, multinational, 4-year PATRICIA trial. PATRICIA enroled women aged 15-25 years with no more than 6 lifetime sexual partners. Women were randomized 1:1 to the HPV-16/18 AS04-adjuvanted vaccine or to control, but only women from the control arm who began sexual intercourse during the study or within 6 months before enrolment, and had no HPV infection detected before the recorded date of their first sexual intercourse, were included in the present analysis. The time between onset of sexual activity and detection of the first cervical HPV infection or development of the first CIN lesion was analyzed using Kaplan-Meier and univariate and multivariable Cox proportional-hazards models. A total of 9337 women were enroled in the control arm of PATRICIA of whom 982 fulfilled the required inclusion criteria for analysis. A cumulative total of 28%, 44%, and 62% of the subjects had HPV infection within 12, 24, and 48 months, respectively. The overall incidence rate was 27.08 per 100 person-years. The most common oncogenic types associated with 6-month persistent infection were HPV-16 (incidence rate: 2.74 per 100 person-years), HPV-51 (2.70), HPV-52 (1.66), HPV-66 (1.14), and HPV-18 (1.09). Increased infection risk was associated with more lifetime sexual partners, being single, Chlamydia trachomatis history, and duration of hormone use. CIN1+ and CIN2+ lesions were most commonly associated with HPV-16, with an overall incidence rate of 1.87 and 1.07 per 100 person-years, respectively. Previous cervical HPV infection was most strongly associated with CIN development. More than 25% of women were

Full Text Available Abstract Background We have previously reported activating mutations of the gene coding for the fibroblast growth factor receptor 3 (FGFR3 in invasive cervical carcinoma. To further analyze the role of FGFR3 in cervical tumor progression, we extended our study to screen a total of 75 invasive tumors and 80 cervical intraepithelial neoplasias (40 low-grade and 40 high-grade lesions. Results Using single strand conformation polymorphism (SSCP followed by DNA sequencing, we found FGFR3 mutation (S249C in all cases in 5% of invasive cervical carcinomas and no mutation in intraepithelial lesions. These results suggest that, unlike in bladder carcinoma, FGFR3 mutation does not or rarely occur in non invasive lesions. Compared to patients with wildtype FGFR3 tumor, patients with S249C FGFR3 mutated tumors were older (mean age 64 vs. 49.4 years, P = 0.02, and were more likely to be associated with a non-16/18 HPV type in their tumor. Gene expression analysis demonstrated that FGFR3 mutated tumors were associated with higher FGFR3b mRNA expression levels compared to wildtype FGFR3 tumors. Supervised analysis of Affymetrix expression data identified a significant number of genes specifically differentially expressed in tumors with respect to FGFR3 mutation status. Conclusion This study suggest that tumors with FGFR3 mutation appear to have distinctive clinical and biological characteristics that may help in defining a population of patients for FGFR3 mutation screening.

To determine whether the number of words displayed in the word prediction software (WPS) list affects text input speed (TIS) in people with cervical spinal cord injury (SCI), and whether any influence is dependent on the level of the lesion. A cross-sectional trial. A rehabilitation center. Persons with cervical SCI (N=45). Lesion level was high (C4 and C5, American Spinal Injury Association [ASIA] grade A or B) for 15 participants (high-lesion group) and low (between C6 and C8, ASIA grade A or B) for 30 participants (low-lesion group). TIS was evaluated during four 10-minute copying tasks: (1) without WPS (Without); (2) with a display of 3 predicted words (3Words); (3) with a display of 6 predicted words (6Words); and (4) with a display of 8 predicted words (8Words). During the 4 copying tasks, TIS was measured objectively (characters per minute, number of errors) and subjectively through subject report (fatigue, perception of speed, cognitive load, satisfaction). For participants with low-cervical SCI, TIS without WPS was faster than with WPS, regardless of the number of words displayed (Pwords displayed in a word prediction list on TIS; however, perception of TIS differed according to lesion level. For persons with low-cervical SCI, a small number of words should be displayed, or WPS should not be used at all. For persons with high-cervical SCI, a larger number of words displayed increases the comfort of use of WPS. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Cervical cancer incidence in western Africa is among the highest in the world. To investigate human papillomavirus (HPV) infection in Guinea, we obtained cervical specimens from 831 women aged 18-64 years from the general population of the capital Conakry and from 77 locally diagnosed invasive cervical cancers (ICC). Human papillomavirus was detected using a GP5+/6+ PCR-based assay. Among the general population, the prevalence of cervical abnormalities was 2.6% by visual inspection and 9.5% by liquid-based cytology. Fourteen of 15 high-grade squamous intraepithelial lesions were visual inspection-negative. Human papillomavirus prevalence was 50.8% (32.1% for high-risk types) and relatively constant across all age groups. Being single or reporting > or =3 sexual partners was significantly associated with HPV positivity. HPV16 was the most common type, both among the general population (7.3%) and, notably in ICC (48.6%). HPV45 (18.6%) and HPV18 (14.3%), the next most common types in ICC, were also more common in ICC than in HPV-positive women with normal cytology from the general population. The heavy burden of HPV infection and severe cervical lesions in Guinean women calls for new effective interventions. Sixty-three per cent of cervical cancers are theoretically preventable by HPV16/18 vaccines in Guinea; perhaps more if some cross-protection exists with HPV45.

Objective: To condcut preliminary study of the value of DTI(diffusion tensor imaging) in human cervical spinal cord. Methods: Twenty-one patients suffering from cervical spondylotic myelopathy and twenty volunteers without any clinical symptoms underwent routine MRI and DTI examination. DTI was performed in six non-collinear directions with single-shot fast spin echo echo, planar imaging sequence(b value = 400 s·mm -2 ). ADC(apparent diffusion coefficient) and FA(fractional anisotropy)values were measured by ROIs(regions of interest) in 4 different level segment spinal cord (C 2/3 , C 3/4 , C 4/5 , C 5/6 ) in normal volunteers, in lesions and normal segmental spinal cord in clinical cases respectively. DTI original images were automatically processed by using IDL (Version 5.6) soft- ware to produce color tensor images. SPSS11.0 software for windows was used for t-test and one-way ANOVA analysis. The difference was considered statistically significant if P 2/3 , C 3/4 , C 4/5 , C 5/6 , were analyzed and it was found that FA value between them had a significant difference by ANOVA, F=159.24, P 2/3 level. However, ADC value between 4 segments had no significant difference(F=2.191, P>0.05). (2)In patients of cervical spondylotic myelopathy, routine MRI T2WI showed abnormal signal in 9 cases, and showed no abnormal signal in 12 dases. In sixteen cases it was found that abnormal patchy green signal on colorized tensor maps appeared on the normal blue spinal cord. Also, in patients of cervical spondylotic myelopathy, there was significant difference in ADC and FA value between lesions and normal spinal cord (paired t test, for ADC, t=2.88, P 2/3 level segment spinal cord in normal volunteers (0.85 ± 0.03) is the highest among other segments. FA value decreases gradually along cervical spinal cord towards the caudal direction. However, the difference of ADC values amongst 4 segments is not significant. DTI colorized tensor maps can show more lesions than routine MRI

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.

Patients who are ventilator dependent as a result of combined cervical spinal cord injury and phrenic nerve lesions are generally considered to be unsuitable candidates for diaphragmatic pacing due to loss of phrenic nerve integrity and denervation of the diaphragm. There is limited data regarding efficacy of simultaneous nerve transfers and diaphragmatic pacemakers in the treatment of this patient population. A retrospective review was conducted of 14 consecutive patients with combined lesions of the cervical spinal cord and phrenic nerves, and with complete ventilator dependence, who were treated with simultaneous microsurgical nerve transfer and implantation of diaphragmatic pacemakers. Parameters of interest included time to recovery of diaphragm electromyographic activity, average time pacing without the ventilator, and percent reduction in ventilator dependence. Recovery of diaphragm electromyographic activity was demonstrated in 13 of 14 (93%) patients. Eight of these 13 (62%) patients achieved sustainable periods (> 1 h/d) of ventilator weaning (mean = 10 h/d [n = 8]). Two patients recovered voluntary control of diaphragmatic activity and regained the capacity for spontaneous respiration. The one patient who did not exhibit diaphragmatic reinnervation remains within 12 months of initial treatment. Surgical intervention resulted in a 25% reduction (p nerve transfers and pacemaker implantation can result in reinnervation of the diaphragm and lead to successful ventilator weaning. Our favorable outcomes support consideration of this surgical method for appropriate patients who would otherwise have no alternative therapy to achieve sustained periods of ventilator independence.

2015-01-01

Chondromyxoid fibroma is a rare benign cartilaginous neoplasm that mostly affects the metaphyseal region of the long bones. The tibia, small tubular bones of the foot, the distal femur and pelvis are common locations, but involvement of the vertebral bones, especially the cervical vertebra, is very rare. Radiographic features show typical characteristics and this tumor often presents as a lobulated, eccentric radiolucent lesion with no periosteal reaction. In addition, geographic bone destruction is seen in all cases. We present an adult female with a one-year history of neck pain, and ultrasound findings that suggest a right paravertebral muscular lesion due to inflammatory or neoplastic origins. The histopathological studies confirmed that the biopsied specimen was a chondromyxoid fibroma of the cervical vertebrae laminae and spinous processes (C3 and C4) with abutting soft tissue. Despite the unusual location and soft tissue presentation, a chondromyxoid fibroma should be considered in the differential diagnosis of a cervical bone lesion

Full Text Available Objective: To find out different grades of cervical intraepithelial lesions of cervix with visual inspection of cervix with acetic acid (VIA. Methods: VIA was carried out in 540 eligible women attending Gynaecology Outpatient Department for gynecological problems. The women underwent a complete clinical evaluation. All screened women (540 were evaluated by colposcopy and biopsies which were taken from different quadrants of the cervix. The final diagnosis was based on histology, which allowed direct estimation of sensitivity, specificity, and predictive values of VIA and colposcopy. Those with abnormal lesions diagnosed by histology were considered as true positive. Results: Out of 540 patients screened, 212 (39.27% were VIA positive. More patients with cervical lesions were detected by VIA than colposcopy. There were 63 (11.67% women with histologic cervical intraepithelial neoplasia (CIN I, which was found in 150 (27.78% by VIA and 138 (25.56% by colposcopy. VIA and colposcopy yielded high grade CIN II in the same number of patients. Biopsy proven cancer was found in 24 (4.45% which was detected in 18 (3.33% by VIA and colposcopy. Sensitivity and specificity of VIA were 68.50% and 70.45% respectively. Positive predictive value was 41.04% and negative predictive value was 90.85%. Conclusions: VIA can differentiate a normal cervix from a precancerous cervix with reasonable accuracy. The sensitivity and specificity of VIA are comparable to the other studies. So VIA may reduce the cervical intraepithelial lesions both in urban and rural areas.

The characteristic features of Papanicolaou (Pap) tests collected from female-to-male (FTM) transgender patients on androgen therapy have not been well defined in the literature. FTM transgender patients require cervical cancer screening with the same recommended frequency as cis-gender females. Dysplasia remains challenging to differentiate from atrophy. Without pertinent history, the atrophic findings in younger transgender patients can be misinterpreted as high-grade dysplasia. A review of all cervical Pap tests of transgender patients receiving androgen therapy (2010-2017) was performed. Bethesda diagnosis, cytomorphological features, HPV testing and cervical biopsy results were reviewed. Eleven transgender patients receiving androgen therapy were identified with 23 cervical Pap tests, 11 HPV tests and five cervical biopsies performed. A review of the Pap tests demonstrated: 57% negative for intraepithelial lesion; 13% unsatisfactory; 13% atypical squamous cells of undetermined significance; 13% atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion; and 4% high-grade squamous intraepithelial lesion. The rates of abnormal tests were higher than our age-matched cis-gender atrophic cohort rates of unsatisfactory (0.5%), atypical squamous cells of undetermined significance (7%), atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (0%) and high-grade squamous intraepithelial lesion (0.5%). The cytological findings from liquid-based preparations included dispersed and clustered parabasal-type cells, scattered degenerated cells, smooth evenly dispersed chromatin, and occasional mild nuclear enlargement and irregularity. Dysplastic cells had larger nuclei, hyperchromatic clumped chromatin, and more irregular nuclear contours. The evaluation of dysplasia can be challenging on Pap tests from transgender patients on androgen therapy. The cohort evaluated had higher rates of unsatisfactory and abnormal Pap tests

Cervical insufficiency is a medical condition during pregnancy in which the uterine cervix softens and begins to dilate before reaching full term, usually between 18 and 22 weeks gestation. It is the most common cause of second trimester pregnancy loss. One clinical technique used to treat cervical insufficiency is the cervical cerclage, a procedure to close the cervix with a purse-string stitch. There are conflicting findings on the efficacy of a cerclage, with most studies relying on statistical evidence. The purpose of this investigation is to examine the mechanical limitations of a cervical cerclage by pressurizing a stitched, synthetic cervix until rupture. A synthetic model of the cervix is generated using ultrasound images collected by clinical collaborators and fabricated with silicon to imitate physiological properties. Medical residents from The George Washington University Hospital stitch the synthetic cervixes using clinical techniques. Pressure transducers record the maximum force on the stitch before rupture. The results of this study will provide insight into the most effective clinical interventions and the mechanism of their success.

Arteriovenous malformation (AVM) of the cervical spinal cord has been known to constitute 5-13% of all spinal AVMs. In contrast to the AVMs located in thoracic or thoraco-lumbar regions, cervical AVM has several characteristic features such as preponderance in younger generation, high incidence of subarachnoid hemorrhage, intramedullary location of the nidus usually fed by the anterior spinal arterial system. We reported three cases of cervical AVMs, which located intramedullary at the levels of C 4 -C 6 , C 1 -C 4 and C 1 -C 2 , respectively. Although selective angiography (vertebral artery, thyrocervical artery, costocervical artery) was essential for the diagnosis of these lesions, computerized tomographic (CT) study with both intrathecal injection of metrizamide and intravenous infusion of contrast material (dynamic and static study) was found to be extremely advantageous in detecting the topography of AVMs in the concerned horizontal planes of the spinal cord. Removal of AVM was given up in one case because of its possible involvement of the anterior spinal artery and central artery shown by CT scan. Removal of AVMs were performed in other two cases. A lateral approach was tried in one case with the AVM located in C 1 -C 2 level, in which CT scan revealed not only an intramedullary but the associated extramedullary AVM in ventrolateral surface of the spinal cord. This operative approach was found to involve less bone removal and markedly reduce spinal cord manipulation necessary to deal with ventrally situated high cervical lesions, compared with a posterior approach with laminectomy.

Full Text Available Background: Carcinoma of cervix is the most common malignancy in female and a major public health problem worldwide. It is the leading cause of death from cancer among women in low resource settings. In Bangladesh, mortality rate is high as most of the cases with cervical cancer are diagnosed in advanced stage. World Health Organization considers cervical cancer as a preventable disease as it can be identified in preinvasive stage. Considerable efforts have been given in detection and treatment of the condition all over the world. A number of cervical cancer screening tests are available. Among them, visual inspection of cervix with acetic acid is rational and can be competently performed by physicians with proper training. Objective: To find out the feasibility of the visual inspection of cervix with acetic acid for the detection of the precancerous lesions of the cervix in our country. Materials and Methods: This cross sectional, analytical study was carried out among the patients attending the outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU who were VIA positive and sent for colposcopy in the colposcopy clinic in the department of Obstetrics and Gynecology in BSMMU from June to December 2004. Two hundred samples were considered for this study. Results: Out of 200 cases, colposcopically 85% had CIN and invasive lesions, 4% had inflammatory lesions while 11% had normal findings. Colposcopy directed punch biopsy revealed positive lesions in 81%, 4% had inflammatory lesions while 15% had normal findings. Conclusion: The study concluded that VIA and colposcopy are the important methods in the evaluation of cervical premalignancy. VIA may be an important tool for screening of cervical cancer in low resource settings as it is simple, easy to perform and cost-effective. After screening, VIA positive cases must be referred for colposcopic evaluation. We can screen cervical cancer by VIA all over the country and thus reduce

Matulic, M.; Soric, J.

1994-01-01

Eighty-four biopsies derived from cervical tissues were analyzed for the presence of human papillomavirus (HPV) DNA types 6, 16 and 18 using Southern blot hybridization. HPV 6 was found in none of the cervical biopsies, and HPV types 16 and 18 were found in 44% of them. The rate of HPV 16/18 positive samples increased proportionally to the severity of the lesion. In normal tissue there were no positive samples, in mild and moderate dysplasia HPV 16/18 was present in 20% and in severe dysplasia and invasive carcinomas in 37 and 50%, respectively. In biopsies from 13 cases with squamous cell carcinoma of the uterine cervix and CIN III lesions HPV 16 was integrated within the host genome. It was concluded that the virus could be integrated at variable, presumably randomly selected chromosomal loci and with different number of copies. Transcription of HPV 16 and 18 was detected in one cervical cancer in HeLa cells, respectively. These results imply that HPV types 16 and 18 play an etiological role in the carcinogenesis of human cervical epithelial cells. (author)

Prophylactic human papillomavirus (HPV) vaccine is the most promissory public health tool for primary prevention of cervical cancer. Immunization of females before the acquisition of HPV infection has the greatest impact in preventing pre-neoplasic lesions and cervical cancer. Current HPV vaccines do not eliminate cervical cancer risk, therefore, screening should continue covering vaccinated as well as women that do not get the vaccine. The strategies that include combination of high-coverage...

Background: Cervical spine and intervertebral discs are potentially prone to functional disorders. Objectives: This study sought type and distribution of different pathologies in the cervical spine and a possible relationship between the MRI findings and the probable risk factors of the degenerative disorders. Materials and Methods: This descriptive cross-sectional research was carried out from october 2000 to january 2002 in three referral centers in Tehran. All the patients had referred for cervical MRI for neck pain and/or radicular pain. Results: Totally 342 patients entered the study. Sixty percent of patients were male. The mean age was 55.1± 12.1 years. Seventy-nine percent of patients had abnormal MRI findings (238 patients (70%) had signs of degenerative processes and 31 patients (9%) had the other findings ) with a total 308 pathologies. The most common findings were disc bulging /protrusion (%21.1), disc dehydration (%20.1), disc herniation (%18.1), and canal stenosis (%17.5). Older age, male gender and history of neck trauma were associated with increasing probability of degenerative changes (P-values<0.05). Conclusion: Types of cervical spine pathologies are comparable to other reports. The anatomical distribution of disc bulging and protrusion in our study are similar to other reports. Likewise age, gender and a history of trauma the neck were closely associated with the degenerative signs on the MR images

Cervical cancer can be successfully prevented by effective treatment. Analyse of success of cryotherapy in LSIL and ASCUS. In retrospective study between January 2016 to March 2017, 3244 PAP test were analysed. 257 patients who had been diagnosed with LSIL and ASCUS from PAP smear were divided in two groups: women who had HPV positive, colposcopic positive and cytologic finding of LSIL or ASCUS treathed with cryotherapy and women with LSIL, ASCUS and negative colposcopy. χ 2 test was used for statistical analysis of data. Analysis of 3244 PAP smears showed negative for intraepithelial lesion or malignancy (NILM) in 90,10% (N-2923), and abnormal in 9,8% (N-321) of women. ASCUS was found in 4,8% (N-156) and ASC-H in 0,2% (N-6), LSIL in 3,1% (N-101), HSIL in 0,64% (N-21). The average age of patients with ASCUS lesion was 41 ± 12 years. After cryotherapy, HSIL had progression in 1,5% (N-1), persistence in 6,3% (N-4) and regression in 91,7% (N-58). Progression occured in 10,5% (N-4) of HSIL, persistence in 52,6% (N-20) and regression in 36,7% (N-14) in 38 women with LSIL lesion after repeated PAP test. Progression occured in 8% (N-10) of LSIL and 4% HSIL (N-5), persistence in 58% (N-72) and regression in 29,8% (N-37) in 124 women with ASCUS lesion after treatment and repeated PAP test. Difference in progression lesions in HSIL between women with cryotherapy (1,5%) and follow-up (10,5%) after LSIL is not significant, but progression to CIN II occured after cryotherapy. CIN III or cervical cancer was not found. Cryotherapy prevents progression of LSIL in HSIL and in cervical cancer. Because of that cryotherapy is successful method in prevention of cervical cancer.

To observe the distribution and potential distribution patterns of osteolytic and sclerotic vertebral involvement in a representative collective of multiple myeloma patients. A total of 66 consecutive patients with a diagnosis of multiple myeloma at initial diagnosis or during follow-up were examined by multidetector reduced-dose computed tomography to evaluate the distribution of bone lesions along the spine with focus on size, location, and lesion character. Confirmation of diagnosis was performed by comparison to follow-up computed tomography or magnetic resonance tomography. If >50 % of all detected malignant lesions occurred in one spinal segment, the distribution pattern was called cervical, thoracic, lumbar, or sacral, otherwise a ''mixed'' pattern was classified. Of a total number of 933 osseous spine lesions, 632 (67.7 %) were classified as malignant (98.9 % of them osteolytic) and 293 (31.5 %) as benign. The distribution pattern analysis yielded two patients (3.8 %) with a cervical, 26 (50 %) with a thoracic, 4 (7.7 %) with a lumbar, one (1.9 %) with a sacral pattern, and 19 cases (36.6 %) showed a mixed distribution pattern. Segment-wise, the mean lesion size was 6.52 ± 2.76 mm (cervical), 8.97 ± 5.43 mm (thoracic), 11.97 ± 7.11 mm (lumbar), and 17.5 ± 16.465 (sacral), whilst, related to the vertebra size, the lesion/vertebra size ratio is decreasing through the whole spine beginning from the top. Multiple myeloma bone lesions occur preferably and are larger in the thoracic and lumbar spine. Moreover, a specific distribution pattern is present in about 60 %. (orig.)

Full Text Available BACKGROUND Textile industry workers face so many health-related challenges compared to the general population. Lymphadenopathy is one of the most common presenting symptoms of these people. This study is done in inhabitants of Tiruppur, a major textile industry area in the state of Tamil Nadu, India, where people work in garment factories for low wages. The aim of the study is to- 1. Evaluate the usefulness of Fine Needle Aspiration Cytology (FNAC as a diagnostic tool in cases of cervical lymphadenopathy. 2. Analyse the various cytomorphological presentations of tuberculous lymphadenopathy. MATERIALS AND METHODS In this study, a spectrum of lesions was diagnosed by fine needle aspiration of lymph nodes of 56 patients presenting with cervical lymphadenopathy. The diseases were categorised into suppurative lymphadenitis, granulomatous lymphadenitis, metastatic tumour deposits and lymphoproliferative disorder. Various morphological presentations of tuberculous lymphadenitis were also analysed. RESULTS From this study, it is observed that the most common diagnosis of cervical lymphadenopathy is reactive lymphadenitis (34%, followed by granulomatous lymphadenitis (30%. Also, among the tuberculosis cases, it is found that majority of cases had only granulomas (45% followed by caseous necrosis with granulomas (28%. CONCLUSION Knowing the usefulness of FNAC, it is concluded that it is a valuable, noninvasive, reliable and cost-effective technique in such a high-risk population. It also helps the clinician to start treatment based on FNAC findings and do the necessary at the earliest.

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 A/sub 2/, N/sub 2/, M/sub 0/ (Pl/sub 0/). 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.

To assess the diagnostic value of integrated PET/MRI for whole-body staging of cervical cancer patients, as well as to investigate a potential association between PET/MRI derived functional parameters and prognostic factors of cervical cancer. The present study was approved by the local institutional review board. Twenty-seven patients with histopathologically confirmed cervical cancer were prospectively enrolled in our study. All patients underwent a whole-body PET/MRI examination after written informed consent was obtained. Two radiologists separately evaluated the PET/MRI data sets regarding the determination of local tumor extent of primary cervical cancer lesions, as well as detection of nodal and distant metastases. Furthermore, SUV and ADC values of primary tumor lesions were analyzed and correlated with dedicated prognostic factors of cervical cancer. Results based on histopathology and cross-sectional imaging follow-up served as the reference standard. PET/MRI enabled the detection of all 27 primary tumor lesions of the uterine cervix and allowed for the correct determination of the T-stage in 23 (85 %) out of the 27 patients. Furthermore, the calculated sensitivity, specificity and diagnostic accuracy for the detection of nodal positive patients (n = 11) were 91 %, 94 % and 93 %, respectively. PET/MRI correctly identified regional metastatic disease (N1-stage) in 8/10 (80 %) patients and non-regional lymph node metastases in 5/5 (100 %) patients. In addition, quantitative analysis of PET and MRI derived functional parameters (SUV; ADC values) revealed a significant correlation with pathological grade and tumor size (p < 0.05). The present study demonstrates the high potential of integrated PET/MRI for the assessment of primary tumor and the detection of lymph node metastases in patients with cervical cancer. Providing additional prognostic information, PET/MRI may serve as a valuable diagnostic tool for cervical cancer patients in a pretreatment setting

2018-03-14

Radiofrequency cervical rhizotomy has been shown to be effective for the relief of chronic neck pain, whether it be due to soft tissue injury, cervical spondylosis, or post-cervical spine surgery. The target and technique have traditionally been taught using an oblique approach to the anterior lateral capsule of the cervical facet joint. The goal is to position the electrode at the proximal location of the recurrent branch after it leaves the exiting nerve root and loops back to the cervical facet joint. The standard oblique approach to the recurrent nerve requires the testing of both motor and sensory components to verify the correct position and ensure safety so as to not damage the slightly more anterior nerve root. Bilateral lesions require the repositioning of the patient's neck. Poorly positioned electrodes can also pass anteriorly and contact the nerve root or vertebral artery. The direct posterior approach presented allows electrode positioning over a broader expanse of the facet joint without risk to the nerve root or vertebral artery. Over a four-year period, direct posterior radiofrequency ablation was performed under fluoroscopic guidance at multiple levels without neuro-stimulation testing with zero procedural neurologic events even as high as the C2 spinal segment. The direct posterior approach allows either unipolar or bipolar lesioning at multiple levels. Making a radiofrequency lesion along the larger posterior area of the facet capsule is as effective as the traditional target point closer to the nerve root but technically easier, allowing bilateral access and safety. The article will review the anatomy and innervation of the cervical facet joint and capsule, showing the diffuse nerve supply extending into the capsule of the facet joint that is more extensive than the recurrent medial sensory branches that have been the focus of radiofrequency lesioning.

Full Text Available Epstein–Barr virus (EBV belongs to the group of gamma-herpes viruses and was the first recognized human oncovirus. EBV is responsible for infectious mononucleosis and multiple lymphoid and epithelial malignancies including B-cell lymphomas (Burkitt lymphoma, Hodgkin lymphoma, and post-transplant lymphoproliferative disorder, various T-cell/NK lymphoproliferative disorders, nasopharyngeal carcinoma, and gastric carcinoma, respectively. In addition, the presence of EBV has been documented in other cancers including breast, prostate, oral, and salivary gland carcinomas. The presence and role of EBV in cervical cancer and its precursor lesions (CIN have also been described, but the results from the literature are inconsistent, and the causal role of EBV in cervical cancer pathogenesis has not been established yet. In the present review, we briefly surveyed and critically appraised the current literature on EBV in cervical cancer and its variants (lymphoepithelioma-like carcinoma as well as its precursor lesions (CIN. In addition, we discussed the possible interactions between EBV and human papilloma virus as well as between EBV and immune checkpoint regulators (PD-L1. Though further studies are needed, the available data suggest a possible causal relationship between EBV and cervical cancer pathogenesis.

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

Riboflavin deficiency can cause a variety of metabolic problems that lead to skin and mucosal disorders. Limited evidence suggests that high intake of riboflavin may reduce overall risks of cancer. However, association of this deficiency with cervical cancer and precancerous lesions are still not definitively known. In this study, we characterized the relationship between plasma and tissue riboflavin levels and C20orf54 protein expression in patients with cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC) as well as the relationship of these levels with human papillomavirus virus 16, 18 (HPV16/18) infections. High-performance liquid chromatography (HPLC) was used to measure blood riboflavin levels in patients with CIN and CSCC, and an enzyme-linked immunosorbent assay (ELISA) was used to determine tissue riboflavin levels in patients with CSCC and matched normal mucous epithelia. The expression of C20orf54 in fresh CSCC and matched tissues were detected by qRT-PCR and western blot, respectively. And it was further confirmed by immunohistochemistry (IHC) with formalin-fixed, paraffin-embedded CIN and CSCC. An HPV genotyping chip was used to analyze HPV infection and typing. The results showed that patients with CIN and CSCC had decreased plasma riboflavin levels as compared with normal controls. There was also significantly decreased riboflavin in tissues from CSCC patients, when compared with normal cervical epithelia. C20orf54 expression were significantly up-regulated in CSCC compared to matched control on both mRNA and protein level. Tissue riboflavin levels were significantly lower in HPV16/18 positive tissue compared with HPV16/18-negative tissue, and an inverse association was found between tissue riboflavin levels and C20orf54 mRNA and protein expression in CSCC. Additionally, C20orf54 was significantly correlated with tumor stages. In conclusion, C20orf54 tend to play a protective role in Uyghur cervical carcinogenesis of

Raman spectroscopy measures the inelastically scattered light from tissue that is capable of identifying native tissue biochemical constituents and their changes associated with disease transformation. This study aims to characterize the Raman spectroscopic properties of cervical tissue associated with the multi-stage progression of cervical precarcinogenic sequence. A rapid-acquisition fiber-optic near-infrared (NIR) Raman diagnostic system was employed for tissue Raman spectral measurements at 785 nm excitation. A total of 68 Raman spectra (23 benign, 29 low-grade squamous intraepithelial lesions (LSIL) and 16 high grade squamous intraepithelial lesions (HSIL)) were measured from 25 cervical tissue biopsy specimens, as confirmed by colposcopy-histopathology. The semi-quantitative biochemical modeling based on the major biochemicals (i.e., DNA, proteins (histone, collagen), lipid (triolein) and carbohydrates (glycogen)) in cervical tissue uncovers the stepwise accumulation of biomolecular changes associated with progressive cervical precarcinogenesis. Multi-class partial least squares-discriminant analysis (PLS-DA) together with leave-one tissue site-out, cross-validation yielded the diagnostic sensitivities of 95.7%, 82.8% and 81.3%; specificities of 100.0%, 92.3% and 88.5%,for discrimination among benign, LSIL and HSIL cervical tissues, respectively. This work suggests that the Raman spectral biomarkers have identified the potential to be used for monitoring the multi-stage cervical precarcinogenesis, forming the foundation of applying NIR Raman spectroscopy for the early diagnosis of cervical precancer in vivo at the molecular level.

Full Text Available Background: Extensive screening programme of cervical Pap smear examination can detect the precancerous and cancerous lesions at an early stage and mortality & morbidity due to these lesions can be reduced. HPV infection is a known etiological agent for cervical cancer. HIV infected women are at higher risk of contracting HPV infection due to immune compromised status. Objective: Present study has been undertaken mainly to detect precancerous & cancerous lesions as well as inflammatory lesions in female patients living with HIV & to emphasize the fact that Pap smear examination should be established as a part of routine protocol for examination in HIV infected women. Methods: The study was carried out on 369 HIV infected females attending Integrated Counselling &Testing Centre of government institute. As controls, 142 females (not falling under high risk category, attending the Obstetrics& Gynaecology OPD with various gynaecological complaints were taken & results were compared. Results: Squamous cell abnormalities were found about four times high as compared to control group. High incidences of squamous cell abnormalities were noted in patients with high parity (parity three or more. Conclusion: Regular gynaecological examination including Pap smear examinations is highly recommended for HIV infected females. Pap smear examination is a simple, cheap, safe & practical diagnostic tool for early detection of cervical cancer in high risk population.

The aim of the present study was to gather information regarding the molecular epidemiology of Human papillomavirus (HPV) and related risk factors in a group of women with low- and high-grade cervical lesions and cancer from the coastal region of Ecuador. In addition, we studied the evolution of HPV variants from the most prevalent types and provided a temporal framework for their emergence, which may help to trace the source of dissemination within the region. We analyzed 166 samples, including 57 CIN1, 95 CIN2/3 and 14 cancer cases. HPV detection and typing was done by PCR-sequencing (MY09/MY11). HPV variants and estimation of the time to most recent common ancestor (tMRCA) was assessed through phylogeny and coalescence analysis. HPV DNA was found in 54.4% of CIN1, 74.7% of CIN2/3 and 78.6% of cancer samples. HPV16 (38.9%) and HPV58 (19.5%) were the most prevalent types. Risk factors for the development of cervical lesions/cancer were the following: three or more pregnancies (OR=4.3), HPV infection (OR=3.7 for high-risk types; OR=3.5 for HPV16), among others. With regard to HPV evolution, HPV16 isolates belonged to lineages A (69%) and D (31%) whereas HPV58 isolates belonged only to lineage A. The period of emergence of HPV16 was in association with human populations (tMRCA=91052 years for HPV16A and 27000 years for HPV16D), whereas HPV58A preceded Homo sapiens evolution (322257 years). This study provides novel data on HPV epidemiology and evolution in Ecuador, which will be fundamental in the vaccine era. Copyright © 2017 Asociación Argentina de Microbiología.

Full Text Available AIM: Cytological evaluation carries a great significance for the early detection and treatment of invasive cervical carcinoma precursors. Pap-smear test are considered as a quite effective screening method for this purpose. This screening can be easily performed at the first step health care centers without causing an economic burden if only selected patients were referred to second and third step medical care centers. In this program we aimed to perform a cross-sectional survey for cervix cancer in Trabzon center and surrounding area using cervical smears obtained at first step health care centers. MATERIAL-METHOD: A total number of 3000 cases with an age range of 25-64 were screened between March and May of 2007. This program was supported by USIDER. Smears obtained with cytological brushes were prepared with conventional methods and stained with Papanicolaou dye. Pap smears were reviewed by two pathologists according to 2001 Bethesda classification. RESULTS: A great majority of the smears (93.3 % were found to be satisfactory, while only 6.7 were found to be insufficient. Analysis of satisfactory cervical smears revealed cervical epithelial cell anomalies in 73 cases (2.4%; of these cases 57 (1.9% had atypical squamous cell of undetermined significance (ASC-US, 11 (0.4 % had low grade squamous intra-epithelial lesion (LSIL, 3 (0.1% high grade squamous intra-epithelial lesion (HSIL, and 2 (0.07 % had squamous cell carcinoma. CONCLUSION: Smears obtained at the first step health care centers were found to be satisfactory in a major proportion of the cases. Screening programs play a great role in the declining of cancer incidence. These screening programs should be included in national health politics. First step health care centers might be used for this purpose concerning the health economics.

The purpose of this study was to identify the prevalence of cervical dentin hypersensitivity in a cross-sectional investigation of Greek adults. Seven hundred and sixty-seven subjects were examined. Participants were patients processed for first examination in the Clinic of Oral Diagnosis and Radiology at the Faculty of Dentistry, University of Athens. The evaluation of hypersensitivity was performed using two methods: for each tooth, the response to a) tactile stimulus and b) air-blast stimulus was measured. Additional factors such as smoking habits, oral health behaviour, consumption of acidic foods, type of toothbrush, daily use of fluoride solution and of desensitising toothpaste, gingival recession and non-carious cervical lesions were recorded and evaluated as causative factors. Descriptive statistics on the demographics of the study sample, of oral health behaviour characteristics and of oral examination findings were performed. Comparisons of these characteristics in the presence or absence of hypersensitivity were conducted with the chi-square test. Data were further analysed using multiple logistic regression modelling. Among study participants, 21·3% had at least one cervical dentin hypersensitivity reaction to the tactile stimulus, and 38·6%, to the air-blast stimulus. Multivariate analysis detected association of the hypersensitivity in tactile or air-blast stimulus with the non-carious lesions and with the gingival recessions. Additionally, a relation between hypersensitivity and air-blast stimulus with gender (female) was found. There was no association between the hypersensitivity in both of the stimuli and the level of education, smoking, consumption of acidic foods, type of toothbrush and daily use of fluoride solution or desensitising toothpaste. The overall prevalence of cervical dentin hypersensitivity in the adult population in Athens ranged from 21·3% to 38·6% depending on the type of stimuli. Cervical non-carious lesions and gingival

Thiryayi, Sakinah A; Marshall, Janet; Rana, Durgesh N

2009-05-01

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

In this study, 44 patients with the ossification of posterior longitudinal ligament, 34 men and 10 women, ranging in age from 38 to 76 years (mean 61) were investigated. They were classified into three categories by the cervical MRI sectional image, Boomerang-type, Triangle-type and Tear-drop-type, and the relationship between these three types and clinical symptom or the results of the surgery was examined. The patients in the Triangle-type were suffered for long term and had many lesions extended over whole interspines. As a result, their spinal cords were in the decrease in the cervical cross-sectional area, so-called in atrophy, and was not expected to improve cross-sectional area or the symptom even in postoperation. On the other hand, the Boomerang-type and the Tear-drop-type were suffered for relatively short term, had the lesion on single spine and were expected, in the excellent reversibility, to improve the cross-sectional area of the spinal cord and the symptom.

A micronucleus is an additional small nucleus formed due to chromosomes or chromosomal fragments fail to be incorporated into the nucleus during cell division. In this study, we assessed the utility of micronucleus counting as a screening tool in cervical precancerous lesions in Thinprep cytological test smears under oil immersion. High risk HPV was also detected by hybrid capture-2 in Thinprep cytological test smears. Our results showed that micronucleus counting was significantly higher in high-grade squamous intraepithelial lesion (HSIL) and invasive carcinoma cases compared to low-grade squamous intraepithelial lesion (LSIL) and non-neoplastic cases. Receiver operating characteristic (ROC) curve analysis revealed that micronucleus counting possessed a high degree of sensitivity and specificity for identifying HSIL and invasive carcinoma. Cut-off of 7.5 for MN counting gave a sensitivity of 89.6% and a specificity of 66.7% (P = 0.024 and AUC = 0.892) for detecting HSIL and invasive carcinoma lesions. Multiple linear regression analysis showed that only HSIL and invasive cancer lesions not age, duration of marital life and number of pregnancy are significantly associated with MN counting. The positive rate of high risk HPV was distinctly higher in LSIL, HSIL and invasive cancer than that in non-neoplstic categories. In conclusions, MN evaluation may be viewed as an effective biomarker for cervical cancer screening. The combination of MN count with HPV DNA detection and TCT may serve as an effective means to screen precancerous cervical lesions in most developing nations.

Full Text Available Cervical cancer is a deadly cancer that clutches lives of the women in most of the cases due to lack of consciousness about the disease in the developing countries. It remains a threat which is second only to breast cancer in overall disease burden for women throughout the world. Cervical cancer is almost a preventable disease by prophylactic vaccine and routine screening. Both Cervarix and Gardasil vaccines have been effective in preventing persistent infection with targeted HPV types and in preventing cervical intraepithelial lesions. It is safe and nearly 100% effective if given before onset of sexual activity. This review article is aimed to explore different aspects of this vaccine as well as to develop awareness among health professionals of different disciplines.

The cervical spine may be specifically involved in crystal-associated arthropathies. In this article, we focus on the three common crystals and diseases: hydroxyapatite crystal deposition disease, calcium pyrophosphate dihydrate (CPPD) deposition disease, and monosodium urate crystals (gout). The cervical involvement in crystal-associated diseases may provoke a misleading clinical presentation with acute neck pain, fever, or neurological symptoms. Imaging allows an accurate diagnosis in typical cases with calcific deposits and destructive lesions of the discs and joints. Most of the cases are related to CPPD or hydroxyapatite crystal deposition; gout is much less common. (orig.)

2013-04-19

Cytomegalovirus (CMV) infection in immunocompetent hosts is generally asymptomatic or may present as a mononucleosic syndrome. Its association with acute cervicitis and vulvovaginitis has rarely been reported. A 24-year-old woman presented with pelvic pain, vulvodynia, abnormal vaginal discharge, burning with urination, fatigue, fever, vomiting and diarrhoea. The vulva and cervix were red with vesicular lesions on the cervix. Genital herpes simplex infection (HSV) was suspected and valacyclovir was given orally. However, serial viral cultures performed 7 weeks apart did not isolate HSV as suspected, but CMV was confirmed by immunofluorescence and early antigen research. Blood tests confirmed an acute CMV infection. Typical inclusions were found at histology. Symptoms resolved slowly with persistence of cervical lesions at 7 weeks from diagnosis. The frequency of CMV genital infection is probably underestimated. The infection is not always asymptomatic and might be confused with genital HSV infection. The clinical course is longer.

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.

Cervical spondylotic myelopathy is usually a chronic and progressive disease. In a few cases, however, dramatic tetraplegia sometimes occurs after even minor injury. We report seven patients (6 males, 1 female, aged from 41 to 63), who suffered from acute myelopathy after an injury. In 5 cases, the injury revealed the cervical spondylotic myelopathy. A hyperextension of the cervical spine was found in 5 cases. The injury was severe in only one case, but there was no bony abnormalities, except arthrosis. The most common cause was a fall. In contrast, severe tetraplegia was found in 4 cases. Spontaneous, but incomplete, recuperation occurred in 4 patients. In all 7 cases, CT scan and MRI showed congenital cervical stenosis associated with cervical spondylosis. The level of disco-osteophytic changes was mainly in C4, C5, C6. On T2-weighted spin-echo image, an increased signal intensity was present in the cord of 3 patients, but was not correlated with the severity of the symptoms, nor with improvement. Surgical treatment was performed in 6 cases: 3 laminectomies, 3 anterior or antero-lateral approaches. Improvement after operative decompression was observed in all but one case, even when the motor or sensory deficit persists for more than one year. Motricity of the inferior limbs improved better than the other deficits, perhaps because of the location of non-reversible lesions in the spinal gray matter. The acute medullary syndrome of cervical spondylotic myelopathy is serious and can cause major handicaps. This complication justifies a preventive surgical attitude when medullar signs are moderate, and cervical imagery shows a spondylotic compression of the cord with congenital stenosis.

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).

Full Text Available Background/Aim. In patients with premalignant cervical lesions, human papillomavirus (HPV infection, at any moment, may be spontaneously eliminated, or may persist or transform cervical epithelium from a lower to a higher degree. Due to that, it is necessary to wisely select the patients who are at high risk of cancer development. The aim of the study was to establish the interdependence between a suspicious Papanicolaou (Pap test and colposcopy with the infection caused by high-risk genotypes of human papillomavirus and the presence of premalignant cervical lesions. Methods. This prospective study used cytological, colposcopy, real-time polymerase chain reaction (PCR of high-risk genotypes of human papillomavirus and histopathological analysis of cervical biopsy specimen. Out of 2,578 female patients sent to cytological analyses in Clinical Center of Montenegro, during 2012, 2013 and 2014, the study included 80 women who had to submit their biopsy specimens due to a suspicious Pap test and atypical colposcopy results. Results. In the group of 80 (3.1%; n = 80/2,578 of the selected female patients with suspicious Pap test and colposcopy, 2/3 or 56 (70% of them had cervicitis, and 1/3 or 24 (30% had cervical intraepithelial neoplasia. The most common type in cervical intraepithelial neoplasia was HPV16 in 8 female patients, ie 61.53% out of the number of infected, or 33.33% out of the total number of premalignant lesions. Conclusion. Patients with suspicious Papanicolaou test, colposcopy results and infection which is caused by high-risk HPV infection (HPV 16 in particular often have premalignant cervical lesions. In these cases, histopathological confirmation of lesions is mandatory, since it serves as a definitive diagnostic procedure.

An estimated 70% of cervical cancers worldwide are attributable to persistent infection with human papillomaviruses (HPV) 16 and 18. Vaccination against HPV 16/18 has been shown to dramatically reduce the incidence of associated precancerous and cancerous lesions. The aims of the present analyses were, firstly, to estimate the clinical and economic burden of disease attributable to HPV in Malaysia and secondly, to estimate long-term outcomes associated with HPV vaccination using a prevalence-based modeling approach. In the first part of the analysis costs attributable to cervical cancer and precancerous lesions were estimated; epidemiologic data were sourced from the WHO GLOBOCAN database and Malaysian national data sources. In the second part, a prevalence-based model was used to estimate the potential annual number of cases of cervical cancer and precancerous lesions that could be prevented and subsequent HPV-related treatment costs averted with the bivalent (HPV 16/18) and the quadrivalent (HPV 16/18/6/11) vaccines, at the population level, at steady state. A vaccine efficacy of 98% was assumed against HPV types included in both vaccines. Effectiveness against other oncogenic HPV types was based on the latest results from each vaccine's respective clinical trials. In Malaysia there are an estimated 4,696 prevalent cases of cervical cancer annually and 1,372 prevalent cases of precancerous lesions, which are associated with a total direct cost of RM 39.2 million with a further RM 12.4 million in indirect costs owing to lost productivity. At steady state, vaccination with the bivalent vaccine was estimated to prevent 4,199 cervical cancer cases per year versus 3,804 cases for the quadrivalent vaccine. Vaccination with the quadrivalent vaccine was projected to prevent 1,721 cases of genital warts annually, whereas the annual number of cases remained unchanged with the bivalent vaccine. Furthermore, vaccination with the bivalent vaccine was estimated to avert RM 45

Despite the potential severity of the lesions, the patient had a favorable outcome, and no surgical approach was necessary. CONCLUSIONS: This case illustrates, by the imaging tests, the complex anatomy of the cervical fasciae and deep neck spaces, and confirms the possibility of conservative management in a great number of laryngeal and hypopharygeal traumatic lesions.

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.

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 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 -3 mm 2 /s, and that of normal cervix tissue was 1.79±0.24 x 10 -3 mm 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.)

A preliminary study to compare cervical lordosis by means of cervical cephalometric analysis, before and after six months of continuous mandibular advancement appliance (MAA) use, and to show how physical therapy posture re-education would improve the cervical lordosis angle. Twenty-two female patients with temporomandibular disorders (TMD) and cervical pain with lordosis 0·05; Shapiro Wilk Test), so the paired comparison of the cephalometric measurements was made by t-test for dependent samples. Angle 1 (OPT/7CVT); angle 3 (CVT/EVT) and angle 4 (2CL/7CL) showed a significant increase in the cervical lordosis. Angle 2 (MGP/OP), angle 5 (HOR/CVT) and the distances C0-C2 and Pt-VER, presented no significant changes. The increase in cervical lordosis implies that six months of continuous MAA use, together with a program of postural re-education, promotes the homeostasis of the craniocervical system.

Introduction: Cervical cancer can be successfully prevented by effective treatment. Aim: Analyse of success of cryotherapy in LSIL and ASCUS. Materials et methods: In retrospective study between January 2016 to March 2017, 3244 PAP test were analysed. 257 patients who had been diagnosed with LSIL and ASCUS from PAP smear were divided in two groups: women who had HPV positive, colposcopic positive and cytologic finding of LSIL or ASCUS treathed with cryotherapy and women with LSIL, ASCUS and negative colposcopy. χ2 test was used for statistical analysis of data. Results: Analysis of 3244 PAP smears showed negative for intraepithelial lesion or malignancy (NILM) in 90,10% (N-2923), and abnormal in 9,8% (N-321) of women. ASCUS was found in 4,8% (N-156) and ASC-H in 0,2% (N-6), LSIL in 3,1% (N-101), HSIL in 0,64% (N-21). The average age of patients with ASCUS lesion was 41 ± 12 years. After cryotherapy, HSIL had progression in 1,5% (N-1), persistence in 6,3% (N-4) and regression in 91,7% (N-58). Progression occured in 10,5% (N-4) of HSIL, persistence in 52,6% (N-20) and regression in 36,7% (N-14) in 38 women with LSIL lesion after repeated PAP test. Progression occured in 8% (N-10) of LSIL and 4% HSIL (N-5), persistence in 58% (N-72) and regression in 29,8% (N-37) in 124 women with ASCUS lesion after treatment and repeated PAP test. Difference in progression lesions in HSIL between women with cryotherapy (1,5%) and follow-up (10,5%) after LSIL is not significant, but progression to CIN II occured after cryotherapy. CIN III or cervical cancer was not found. Conclusion: Cryotherapy prevents progression of LSIL in HSIL and in cervical cancer. Because of that cryotherapy is successful method in prevention of cervical cancer. PMID:28974850

Cervical cancer is a major public health problem in resource-limited settings, particularly among HIV-infected women. Given the challenges of cytology-based approaches, the efficiency of new screening programs need to be assessed. Community and hospital-based clinics in Gaborone, Botswana. To determine the feasibility and efficiency of the "see and treat" approach using visual inspection acetic acid (VIA) and enhanced digital imaging (EDI) for cervical cancer prevention in HIV-infected women. A 2-tier community-based cervical cancer prevention program was implemented. HIV-infected women were screened by nurses at the community using the VIA/EDI approach. Low-grade lesions were treated with cryotherapy on the same visit. Women with complex lesions were referred to our second tier specialized clinic for evaluation. Weekly quality control assessments were performed by a specialist in collaboration with the nurses on all pictures taken. From March 2009 through January 2011, 2175 patients were screened for cervical cancer at our community-based clinic. Two hundred fifty-three patients (11.6%) were found to have low-grade lesions and received same-day cryotherapy. One thousand three hundred forty-seven (61.9%) women were considered to have a normal examination, and 575 (27.3%) were referred for further evaluation and treatment. Of the 1347 women initially considered to have normal exams, 267 (19.8%) were recalled based on weekly quality control assessments. Two hundred ten (78.6%) of the 267 recalled women, and 499 (86.8%) of the 575 referred women were seen at the referral clinic. Of these 709 women, 506 (71.4%) required additional treatment. Overall, 264 cervical intraepithelial neoplasia stage 2 or 3 were identified and treated, and 6 microinvasive cancers identified were referred for further management. Our "see and treat" cervical cancer prevention program using the VIA/EDI approach is a feasible, high-output and high-efficiency program, worthy of considering as an

Sympathectomy has been achieved by a variety of methods but each has its limitations. These include lack of tissue specificity, incomplete lesioning, and the age range of susceptibility to the lesioning. To circumvent these drawbacks, an immunotoxin was constructed using a monoclonal antibody against the noradrenergic specific enzyme dopamine beta-hydroxylase (D beta H) coupled via a disulfide bond to saporin, a ribosomal inactivating protein. Three days after intravenous injection of the anti-D beta H immunotoxin (50 micrograms) into adult Sprague-Dawley rats, 66% of neurons in the superior cervical ganglia were chromatolytic. Superior cervical ganglia neurons were poisoned in 1 day old and 1 week old (86% of neurons) neonatal rats following subcutaneous injection of 3.75 and 15 micrograms, respectively. The anti-D beta H immunotoxin will be a useful tool in the study of the peripheral noradrenergic system in adult and neonatal animals.

Full Text Available Tafazzin (TAZ is often aberrantly expressed in some cancers, including rectal cancer and thyroid neoplasms. However, the function of TAZ in cervical cancer cells remains unknown. This study aims to explore the expression and function of TAZ in cervical cancer cells. Here, we determined the expression of TAZ protein in normal cervical tissue (NC, n = 27, high-grade squamous intraepithelial lesions (HSIL, n = 26 and squamous cervical carcinoma (SCC, n = 41 by immunohistochemistry, the expression of TAZ protein gradually increased from NC to HSIL to SCC. TAZ was overexpressed or down-regulated in cervical cancer cells by stably transfecting a TAZ-expressing plasmid or a shRNA plasmid targeting TAZ. In vitro, the cell growth curves and MTT assays showed that TAZ may promote the growth and viability of cervical cancer cells. In vivo, xenografts experiment showed that TAZ may increase tumor-forming ability. The percentage of apoptosis cells analyzed by FACS and TUNEL assays consistently showed that TAZ inhibits apoptosis in cervical cancer cells. Furthermore, the Cleaved Caspase 9 and Cleaved Caspase 3 were down-regulated by TAZ in cervical cancer cells. Taken together, this study demonstrated that TAZ is overexpressed in cervical cancer and may promote tumorigenicity of cervical cancer cells and inhibit apoptosis.

Purpose: To investigate the value of diffusion-weighted MR imaging (DWI) in detection of cervical cancer, and to determine the diagnostic accuracy of apparent diffusion coefficient (ADC) values for evaluating cervical cancer before and after chemoradiotherapy. Materials and methods: Thirty-three patients with cervical squamous carcinoma and 20 patients with other pelvic abnormalities underwent diffusion-weighted imaging (DWI) in addition to routine MR imaging. The ADC values of normal cervical tissue, cervical area before and after chemoradiotherapy were measured and compared. Receiver operating characteristic (ROC) analysis was employed to investigate whether ADC values could help in discrimination among normal cervical tissue, cervical cancer before and after therapy, and to obtain the optimal ADC threshold value. Results: Cervical cancer lesion demonstrated obviously hyperintensity on DWI images. The mean ADC value of cervical carcinoma (1.110 ± 0.175 x 10 -3 mm 2 /s) was significantly lower than that of normal cervical tissue (1.593 ± 0.151 x 10 -3 mm 2 /s) (P -3 mm 2 /s) was significantly higher than that before therapy (1.013 ± 0.094 x 10 -3 mm 2 /s) (P -3 mm 2 /s, between cervical area before and after therapy was 1.255 x 10 -3 mm 2 /s, between normal cervical tissue and cervical area after therapy was 1.525 x 10 -3 mm 2 /s. The sensitivity and specificity were 100% and 84.8%, 95.5% and 100%, 70% and 81.8%, respectively. Conclusion: DWI can be applied for the detection of cervical cancer because of its superior disease contrast with normal tissue. The measurement of the ADC values can be a useful tool to monitor the response to therapy for cervical carcinoma.

To investigate the early effectiveness of the Discover cervical artificial disc replacement in treating cervical spondylosis. Qualified for the selective standard, 24 patients with cervical spondylosis were treated between March 2010 and March 2011. Of 24 patients, 13 patients underwent anterior cervical decompression and fusion (ACDF) (ACDF group, between March 2010 and September 2010) and 11 patients underwent Discover cervical artificial disc replacement (CADR group, between September 2010 and March 2011). There was no significant difference in gender, age, disease duration, lesions typing, and affected segments between 2 groups (P > 0.05). The operative time, blood loss, and complications were recorded. Japanese Orthopaedic Association (JOA) scores, Neck Disability Index (NDI) scores, and Odom's scores were used to evaluate the postoperative effectiveness. In CADR group, the cervical range of motion (ROM) in all directions, and prosthesis eccentricity were measured before and after operation. Symptoms disappeared and no complication occurred after operation in the patients of 2 groups. The patients were followed up 12 to 18 months (mean, 15.3 months) in ACDF group and 6 to 12 months (mean, 9.6 months) in CADR group. The NDI scores in CADR group were significantly higher than those in ACDF group at 1, 3, and 6 months (P 0.05). According to Odom's score at last follow-up, the results were excellent in 6 cases, good in 4 cases, and fair in 3 cases with an excellent and good rate of 76.92% in ACDF group, and were excellent in 9 cases, good in 1 case, and poor in 1 case with an excellent and good rate of 90.91% in CADR group, showing no significant difference (chi2 = 3.000, P = 0.223). The patients in CADR group had significant limit of cervical joint ROM in flexion and extension and right bending at 1 month (P value (P < 0.05). Meanwhile, ROM in left bending were bigger than that in right bending in replaced segment and upper segment (P < 0.05), and the ROM

Cervical chondrocutaneous branchial remnants are congenital, benign and rare neck masses. These anomalies are limited in the literature, reported mostly as case reports. Cervical chondrocutaneous branchial remnant is always present at birth, and the lesion is usually unilateral. Understanding and treatment of cervical chondrocutaneous branchial remnants requires knowledge of the related embryology. From January 2005 to December 2008, 17 patients with mean age of 32 months (range from 2 months to 15 years) with CCBRs were treated at the Division of Pediatric Surgery, Department of Plastic and Reconstructive Surgery and Burns at the Institute for Mother and Child Health Care, Belgrade, Serbia. The following objections were recorded: sex, lesion side, surgical data, associated malformations and pathohistology findings. There were 7 females and 10 males, 4 with bilateral presences. Five children had associated anomalies, as follows: vesicoureteral reflux, atrial and ventricular septal defect, ventricular septal defect, branchiootorenal syndrome and preauricular sinus. There was a positive family history in one patient. Fifteen patients (88%) were treated with complete surgical excision and no connections with deep underlying structures of the neck were found. There were no complications at surgery. No recurrence was found during follow-up. Histopathology analysis revealed both, hyaline and elastic cartilage. Cervical chondrocutaneous branchial remnants are rare anomalies arising from branchial arch, probably originally from remnants of first or second arch. Surgical excision is the treatment of choice. From our experience, we suggest surgical treatment early in childhood because of esthetic reason, simplicity of the intervention and low complication rate. Also, the abdominal ultrasound and cardiac examination is recommended because of associated anomalies. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Cervical cancer continues to be a major public health problem in India in the absence of wide spread organised cervical screening programs. Visual inspection of the cervix with acetic acid (VIA is an effective, inexpensive screening test that can be combined with simple treatment procedures for early cervical lesions, provided by trained health workers. We report 7 years experience in early detection of cervical cancer and pre-cancers using the VIA test in a community-based program in rural Andhra Pradesh, India where there are no existing organised cervical screening programs. Materials and Methods: Eligible women aged between 26 and 60 were opportunistically screened by trained health wor kers using the VIA test. Women who tested positive were further evaluated and those with cervical lesions were treated either by cryotherapy in the screening clinic or referred to a higher center. Results: A total of 18,869 women were screened by a single round of VIA testing with a positive rate of 10.75%. Biopsy proven high-grade squamous intraepithelials (HSILs were 90 (0.48% and low-grade squamous intraepithelials (LSILs were 43 (0.28%. The overall prevalence of cervical intraepithelial neoplasia (CIN 2+ lesion rate is 1.05%. A total of 312 (1.65% cryotherapies were done and 49 women underwent hysterectomy. Conclusions: VIA by trained female health workers is a safe, acceptable, and effective test that can save lives from cervical cancer even in remote areas with few resources. These results have important implications for efficient service delivery in cervical screening programs in low-resourced settings.

To evaluate the prevalence of human papillomavirus (HPV) cervical infection in women from the South American Guarani Indian tribe located in the rain forest of Misiones, north-eastern Argentina; a region with a high incidence of cervical carcinoma. A cross-sectional cytological and HPV screening of sexually active Guarani women from nine Indian settlements was conducted. Demographic data, information about sexual behavior, and gynaecological history were recorded. Fresh cervical specimens from 239 patients were collected, of which 207 were included in this study. Cytology and microbiological detection were carried out by the Papanicolaou and Gram stain methods, respectively. HPV detection and typing were analyzed by PCR and RFLP. Pap smears in 96% of all patients showed an inflammatory pattern. A possible etiologic agent was found in 58% of cases: 52% Trichomonas vaginalis, 35% Gardnerella vaginalis and 13% Candida sp. Seven cases had cytological changes compatible with Low Grade Intraepithelial Lesion (LGSIL), one with High Grade Intraepithelial Lesion (HGSIL) and one in situ cervical cancer. The prevalence for generic HPV infection was 64% (133/207). Genotyping gave a 26% prevalence for HPV types 16/18, 13% for types 6/11 and 30% for other types, with nine mixed infections. This work reports for the first time the prevalence of cervical HPV infection in Guarani women. Nearly all Guarani women had some grade of cervical disease. Generic HPV infection prevalence was elevated (64%), with predominance of high risk types 16/18. A large variety of viral types was detected, including high to intermediate risk types not found previously in the region.

Cervical screening with cytology has been the basis for substantial reductions in cervical cancer incidence and mortality in most high-income countries over the last few decades. More recently, there have been two key, parallel developments which have prompted a major re-consideration of cervical screening. The first is the emergence of evidence on the improved sensitivity of human papillomavirus (HPV) DNA testing compared to cytology, and the second is the large-scale deployment of prophylactic vaccination against HPV. A key challenge to be overcome before HPV screening could be introduced into national cervical screening programs was the specificity of an infection, for detection of precancerous lesions. This has been done in three ways: (1) by considering the appropriate age for starting HPV screening (30 years in unvaccinated populations and 25 years in populations with mature vaccination programs and high vaccine uptake) and the appropriate screening interval; (2) via development of clinical HPV tests, which are (by design) not as sensitive to low viral loads; and (3) by introducing effective triaging for HPV-positive women, which further risk-stratifies women before referral for diagnostic evaluation. This review discusses these major developments and describes how the benefits of HPV screening are being optimized in both unvaccinated and vaccinated populations.

Cervical spondylolysis, which is defined as a cleft between the superior and inferior articular facets of the articular pillar, is a rare condition. The sixth cervical vertebra (C6) is the level most commonly affected. Cases involving C2, C3, C4, or C5 have also been reported. However, to date, no case of C7 spondylolysis has been reported. To present a rare case of bilateral spondylolysis of the seventh cervical vertebra (C7) in a 58-year-old man. A case report. A 58-year-old man visited our hospital with chronic posterior neck pain radiating to the left upper extremity. Magnetic resonance imaging (MRI) study revealed left foraminal disc herniations at C5-C6 and C6-C7. Cervical spondylolysis involving C7 was discovered incidentally during computed tomography (CT)-guided transforaminal steroid injection. Plain radiographs, CT images, and MRIs were reviewed thoroughly once again. The patient's symptoms were relieved after he received CT-guided transforaminal steroid injections. Plain radiographs revealed a radiolucent defect in the articular pillar and cleft at the spinous process of C7. Computed tomography confirmed bilateral spondylolysis and spina bifida occulta of the C7 vertebra. Magnetic resonance imaging revealed absence of edema, which was suggestive of a chronic lesion. Involvement of C7 is not exceptional in a case of cervical spondylolysis. Copyright © 2010 Elsevier Inc. All rights reserved.

Multifocal tumors within the same parotid gland are very rare. We treated 13 patients with multiple tumorous lesions within the unilateral parotid gland. We evaluated the multiple nodules by CT-sialography or magnetic resonance imaging (MRI). These imagings showed clearly two or more distinct nodular-appearing lesions. Recurrent pleomorphic adenoma (6 patients) was predominant, followed by Whartin's tumor (3 patients). The other lesions were two differential parenchymal tumors (polymorphous low grade adenoma/adenoma) within the same gland, a malignant lymphoma, a squamous cell carcinoma metastatic to the gland, and a tuberculous lesion. On palpitation, 9 of the patients had an unilateral tumor, one a palpable parotid mass in the gland, and the other four had two or more tumors in the unilateral gland. The patients with intra-parotid lymph node and metastatic lesions had extra-parotid cervical adenopathy. The clinical features and the differential diagnosis of the unilateral multiple tumors lesions of the parotid gland are discussed. (author)

To investigate changes in clinical (physical and psychological) features of individuals with chronic whiplash-associated disorder who had previously undergone cervical radiofrequency neurotomy at the time point when the effects of radiofrequency neurotomy had dissipated and pain returned. Prospective cohort observational trial of consecutive patients. Tertiary spinal intervention centre in Calgary, Alberta, Canada. A total of 53 consecutive individuals with chronic whiplash-associated disorder. Individuals underwent radiofrequency neurotomy and were assessed before radiofrequency neurotomy, at 1 and 3 months postprocedure, and then after the return of pain (approximately 10 months postprocedure). Quantitative sensory tests (pressure; thermal pain thresholds; brachial plexus provocation test), nociceptive flexion reflex, and motor function (cervical range of movement; craniocervical flexion test) were measured. Self-reported disability, psychological distress, pain catastrophization, and posttraumatic stress disorder symptoms also were measured. Upon the return of pain after radiofrequency neurotomy, levels of disability increased (P .22). There were no significant changes in pressure hyperalgesia (P > .054) or craniocervical flexion test performance (P > .07) after the return of pain. Psychological distress and pain catastrophizing increased significantly after the return of pain (P .13). However, there was no difference in number or severity of posttraumatic stress symptoms after the return of pain (P > .30). Physical and psychological features of chronic whiplash-associated disorder are modulated dynamically with cervical radiofrequency neurotomy. These findings indicate that peripheral nociception is involved in the manifestations of chronic whiplash-associated disorder in this cohort of individuals.

2017-01-01

To date, cervical carcinoma complicated with Cushing's syndrome were all diagnosed as small cell carcinoma histo- logically, but not adenosquamous carcinoma. Here the authors present the diagnosis, management, and prognosis of a case of melanocytic cervical adenosquamous carcinoma complicated with Cushing's syndrome. A 28-year-old woman was admitted with the chief complaint of post-coital bleeding for one month. Gynecological examination revealed a nodular yellowish-pigmented vegetation (6x5 cm) on the cervix. Laboratory findings proved the diagnosis of Cushing's syndrome. Histopathological diagnosis showed the adenosquamous carcinoma with melanoma differentiation. Immunohistochemical stainings for melanoma A and anti- adrenocorticotropic hormone (ACTH) were positive in the majority of the tumor cells, which indicated that this melanocytic cervical carcinoma lesion was the source of ectopic ACTH production resulting in Cushing's syndrome. This is a unique case of a rare type of cervical carcinoma.

Rheumatoid arthritis (RA) is a polyarthritis caused by inflammatory overgrowth of synnovium known as pannus. Small joints of hands and feet are most frequently involved, followed by cervical spine, particularly the craniocervical junction. The cervical spine involvement may be a cause of a range of neurological complications. Imaging diagnostics of the spine in RA patients include radiograms, CT and MRI. Their purposes is to evaluate type, extension and advancing of the changes. The following lesions can be found in the cervical spine at least in 30% of RA patients with disease duration more than 10 years: subaxial subluxations, apophyseal joint erosions, odontoid erosions, apophyseal joint sclerosis, intervertebral space narrowing, and osteophytosis.These lesions can be easily detected with radiographic examinations whereas the presence of the pannus can be found only with MRI or contrast enhanced CT. The most dangerous complication of RA in the cervical spine is atlantoaxial subluxation. It can be well demonstrated with MRI.Even it is frequently asymptomatic, there is always the possibility of neurological symptoms from compression of the spinal cord by the odontoid process. Therefore, MRI of the cervical spine should be considered in all RA patients. (author)

Cervical Cancers Require the Continuous Expression of the Human Papillomavirus Type 16 E7 Oncoprotein Even in the Presence of the Viral E6 Oncoprotein

High-risk human papillomaviruses (HPV), such as HPV-16, are etiologic agents of a variety of anogenital and oral malignancies, including nearly all cases of cervical cancer. Cervical cancers arising in transgenic mice that express HPV-16 E7 in an inducible manner require the continuous expression of E7 for their maintenance. However, in HPV-associated cancers in vivo, E6 and E7 invariably are co-expressed. In this study, we investigated whether cervical cancers rely on the continuous expression of E7 in the context of constitutively expressed E6. We placed the inducible HPV-16 E7 transgene onto a background in which HPV-16 E6 was constitutively expressed. In transgenic mice with high-grade cervical dysplastic lesions and cervical cancer, repressing the expression of E7 led to the regression of all cancers and the vast majority of high-grade dysplastic lesions. In addition, cervical cancers were occasionally observed in transgenic mice in which E7 was repressed and then re-expressed. Our findings therefore indicate that even in the presence of constitutively expressed E6, the continuous expression of E7 is required for the maintenance of cervical cancers and most precancerous lesions. These data have important implications for the potential clinical use of drugs designed to inhibit the expression and/or function of E7 to treat HPV-associated cancers. PMID:22700879

To assess the effectiveness of cryotherapy treatment delivered by general practitioners in primary care settings, as part of a screen-and-treat approach for cervical cancer prevention. Women aged between 25 and 49 years residing in San Martin, Peru, who were positive on visual inspection screening were treated, if eligible, with cryotherapy following biopsy. At 12 months post cryotherapy treatment the participants were evaluated for treatment effectiveness and examined by visual inspection and Papanicolaou test and, if positive, referred to a gynecologist for colposcopy and biopsy. Cryotherapy treatment was performed for 1398 women; of these, 531 (38%) had a histology result of cervical intraepithelial neoplasia (CIN). Cryotherapy effectively cured CIN in 418 (88%) women, including 49 (70%) women with a baseline diagnosis of CIN 3. Cryotherapy is an effective treatment for cervical precancerous lesions; it can easily be administered by general practitioners in primary care settings following visual inspection screening.

2014-11-01

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.

A midline cervical cleft (MCC) is a rare congenital anomaly due to failure of fusion of the first and second branchial arches during embryogenesis. It may present as a midline defect of the anterior neck skin with a skin projection or sinus, or as a subcutaneous fibrous cord. This report evaluates the clinical features and surgical management of an MCC. We analyzed a series of 4 patients with an MCC successfully treated at Great Ormond Street Hospital for Children in London. Three male patients and 1 female patient between 4 and 11 months of age were found to have an MCC. Each patient presented with an erythematous, fibrous band of tissue extending between the chin and the suprasternal notch. Treatment comprised surgical excision of the lesion and Z-plasty repair. We present the embryology, common clinical presentation, investigations, differential diagnosis, and histology, along with a literature review, of this uncommon malformation of the anterior neck. An MCC is a differential diagnosis to consider when assessing a child with a midline cervical lesion. Early surgical excision with Z-plasty repair of the soft tissue defect is the treatment of choice to prevent long-term complications.

Human Papillomaviruses (HPVs) are etiologically associated to cervical carcinoma. In order to evaluate HPV infection and its relationship with the high frequency of this neoplasia in Quechua women from Jujuy (Argentina), 271 cervical samples from preneoplastic and neoplastic lesions (biopsies) and normal controls (cytologies) were studied. Detection and typing were performed using PCR-RFLP or PCR-hybridization and the HPV-16 variability in L1 and E6 genes (by PCR-hybridization) was analysed. HPV was detected in 52% of controls, 91% of low-grade lesions, 97% of high-grade lesions and 100% of invasive carcinomas, corresponding 55% to HPV-16. HPV-16 European variants were predominant, most of them being non-prototypic strains. The high frequency of high risk infection types and the raised proportion of HPV-16 non-prototypic variants related to a greater oncogenic potential could explain, in part, the high cervical cancer frequency of this native population. These data may contribute to disease control and vaccinal formulation.

The aim of this study was to examine the association between CD4 count, human papilloma virus (HPV) infection, and the risk of cervical intraepithelial neoplasia among HIV-infected women. A cross-sectional study was conducted among 104 HIV-infected women attending an antiretroviral therapy clinic. They underwent Pap smear and cervical HPV DNA testing. The overall prevalence of HPV infection was 57.7%. HPV 16 was the commonest genotype found (38.5%); HPV 16 and 18 put together contributed to 73.3% of HPV infection; 27.5% of HIV-infected women had squamous cell abnormalities. Cervical intraepithelial neoplasia was less likely among women with CD4 count > 500/mm 3 (12%) and in those without opportunistic infections (17.8%). The prevalence of high-risk HPV infection was higher in women with high-grade squamous intraepithelial lesions or greater lesions (85.7%) as compared to women with normal cytology (52.1%). The high prevalence of HPV infection and cervical intraepithelial neoplasia in HIV-infected women warrants the need for regular Pap smear screening in these women and routine HPV vaccination for adolescents to reduce the burden of cervical cancer in India. © 2016 Japan Society of Obstetrics and Gynecology.

The reproducibility of the histological diagnosis of cervix specimens processed by the Pathology Service of the San Juan de Dios Hospital from January to December 2010 was determined. When operational failures were detected, possible improvement processes were proposed, guided by the study's findings. A moderate concordance for the Bethesda System and poor to moderate for the classification of Cervical Intraepithelial Neoplasia, was obtained after analyzing the diagnoses issued by the observers when comparing the pairs of pathologists. The concordance was moderate when comparing each pathologist with the standard for both classifications. The correlation was excellent when comparing the Classification Cervical Intraepithelial Neoplasia versus the Bethesda System. The categories with highest concordance were high-grade intraepithelial lesion and cervical intraepithelial neoplasia 3 and minor agreement were low-grade intraepithelial lesion and cervical intraepithelial neoplasia 2. The results agree and in some cases the results exceed the reproduction noted in the literature world medical [es

To find cytology changes among women attending obstetrics and gynaecology clinic with complaints of vaginal discharges. This descriptive hospital-based cytological study was conducted at the outpatient clinic of the obstetrics and gynaecology department. Two hundred women with complaints of vaginal discharge were selected. Their detailed histories were documented on a special request form. Pap smears were then obtained and sent for cytological examination to the cytopathology department. All low-grade squamous intraepithelial lesion (LSIL) cases were advised to follow-up with Pap smears in the next 6-12 months. Those with high-grade squamous intraepithelial lesion (HSIL) were further investigated by a cervical biopsy and managed accordingly. The statistical analysis was performed using, the Statistical Package for Social Science (SPSS). Chi-square and cross-tabulation were used in this study. The cytological examination of Pap smears showed no changes (i.e. negative findings) in 88 (44%) cases, while Candida species infection was the most prevalent, which was found in 67 (33.5%) of the cases. Bacterial vaginosis was found in 39 women (19.5%); 6 women (3%) were reported with dyskaryotic changes. Two cases were found to have LSIL and 4 women had HSIL. Infection is common among the illiterate group of women. Women with vaginal discharges should undergo screening tests for evaluation by cervical smear for the early detection of cervical precancer conditions. There is an urgent need to establish a screening program for cervical cancer in Sudan.

Full Text Available BACKGROUND The cytologic diagnosis of cervical smears has become a very important screening test for the detection of pre-invasive and invasive cervical epithelial abnormalities. MATERIALS AND METHODS It is a prospective study conducted for a period of 1 year in 100 women who fulfilled the inclusion criteria. Colposcopy, PAP smear and biopsy were done. RESULTS Majority 70.5% i.e., (12/17 of CIN occurred in the age group of 30-49 years. Among the 9 women who took OCP, 12% (2/17 had CIN. Incidence of CIN in the permanently sterilized group was 59% (10/17 and among IUCD user was 5.9% (1/17. Among women who were diagnosed to have CIN, 70.5% (12/17 complained of excessive vaginal discharge 11.7% (2/17 of women had post-coital bleeding. PAP smear had a sensitivity of 29% and a specificity of 88% which was attributed to the high number of false, negative smears. Colposcopy showed a sensitivity of 82% and a specificity of 81%. Sensitivity was more than pap smear but specificity was less than pap smear. Accuracy of Colposcopy was found to be 82% which was comparatively more accurate than pap smear (78%. CONCLUSIONS COLPOSCOPY offers an excellent tool in evaluating cervical lesions. It is an easy and perspective method and its importance lies in teaching, diagnosis and management of cervical lesions, both neoplastic and non-neoplastic.

Segmental resection and anastomosis of oesophageal lesions are not performed as a routine clinical practice because of complications and associated problems, whereas tracheal resection and anastomosis are a routine clinical practice. In this experimental study, we resected a segment of cervical oesophagus and replaced it with a tracheal segment. In eight dogs (mixed races), weighing 20-30 kg, ageing 1-2 years, under general anaesthesia, through a cervical incision, 5 cm of cervical trachea was separated while preserving its attachments to surrounding fibroareolar tissues. Afterwards, 5 cm of the oesophagus was resected and replaced with a prepared segment of the trachea. Oral liquids were started at the first post-operative day; the animals were kept for 2 months and then euthanized. Quality of swallowing and voice were evaluated. After an autopsy, anastomoses were examined grossly and histopathologically. No complications occurred during surgery. Swallowing function and voice were normal in all eight dogs after the operation. No sign of aspiration was seen in clinical and radiographic examinations after starting oral diet. In autopsy examination, anastomoses were patent without narrowing or abnormal mucosal changes. Remarkable histopathological findings in replaced tracheal segments were squamous metaplasia, atrophy and degeneration of mucosal glands and degeneration of cartilages. Replacement of a segment of the oesophagus with an autogenous tracheal segment is a practical procedure with low complications and can probably be used for the treatment of cervical oesophageal lesions in human beings.

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.

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.

Venous hypertensive myelopathy (VHM) results from spinal vascular malformations of arteriovenous shunting that increases spinal venous pressure, leading to congestive edema and neurologic dysfunction. There has been no report of VHM associated with cervical spondylotic myelopathy (CSM). The aim of this study was to report an extremely rare case of VHM likely due to CSM. This study is a case report and review of the literature. The patient was a 51-year-old man with CSM exhibiting relatively rapid neurologic deterioration with an abnormal expansion of a centromedullary hyperintense lesion on T2-weighted magnetic resonance imaging (MRI) in the absence of traumatic injury. Neurologic examination and radiologic imaging were taken by various means. The patient developed a cervical radiculopathy, followed by gait disturbance and motor weakness. The MRI of the cervical spine demonstrated spinal canal stenosis due to disc bulging and flavum hypertrophy at the C5/C6 and C6/C7 levels as well as hyperintense area over the C5-C7 levels on T2-weighted images. Although decompression surgery was planned, an acute inflammatory process such as transverse myelitis or demyelinating disease other than cord compression was also considered, and the patient received intravenous steroids. His walking improved for several days. However, his symptoms then became significantly worse, and he had difficulty walking. Subsequent MRI demonstrated marked progression of the T2 hyperintense lesion over the C4-T1 vertebral levels. Flow voids were also noted on the dorsal surface of the upper cervical cord on T2-weighted MRI. His lab work, medical history, and the local enhancement on contrast-enhanced MRI indicated low probability of spinal inflammatory diseases. Therefore, the decision was made to perform anterior cervical discectomy and fusion surgery on two levels. Following surgery, his symptoms improved promptly. Our case indicates that VHM could be caused by spondylotic cord compression in the

Full Text Available Cervical cancer that is a disease, in which malignant (cancer cells form in the tissues of the cervix, is one of the fourth leading causes of cancer death in female community worldwide. The cervical cancer can be prevented and/or cured if it is diagnosed in the pre-cancerous lesion stage or earlier. A common physical examination technique widely used in the screening is called Papanicolaou test or Pap test which is used to detect the abnormality of the cell. Due to intricacy of the cell nature, automating of this procedure is still a herculean task for the pathologist. This paper addresses solution for the challenges in terms of a simple and novel method to segment and classify the cervical cell automatically. The primary step of this procedure is pre-processing in which de-nosing, de-correlation operation and segregation of colour components are carried out, Then, two new techniques called Morphological and Statistical Edge based segmentation and Morphological and Statistical Region Based segmentation Techniques- put forward in this paper, and that are applied on the each component of image to segment the nuclei from cervical image. Finally, all segmented colour components are combined together to make a final segmentation result. After extracting the nuclei, the morphological features are extracted from the nuclei. The performance of two techniques mentioned above outperformed than standard segmentation techniques. Besides, Morphological and Statistical Edge based segmentation is outperformed than Morphological and Statistical Region based Segmentation. Finally, the nuclei are classified based on the morphological value The segmentation accuracy is echoed in classification accuracy. The overall segmentation accuracy is 97%.

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.

The purpose of this study is to report an unusual variant of cervical squamous cell carcinoma, not associated with either human papillomavirus infection or antecedent squamous intraepithelial lesions. Five women had a diagnosis of invasive cervical cancer discovered at hysterectomy performed for prolapse (two cases), leiomyoma (one case), or a vaginal fistula (two cases). The women ranged in age from 47 to 78 years (mean 59 years). Four of the five had a history of normal Papanicolaou (Pap) smears; the other had a Pap smear diagnosis of atypical squamous cells of undetermined significance (ASCUS). All had large cervical tumors (two with parametrial involvement and one with vaginal involvement) that showed extensive keratin formation, an inverted pattern of growth, and, except for one case, minimal cytologic atypia. There was extensive hyperkeratosis and parakeratosis adjacent to each tumor; none had evidence of squamous intraepithelial lesion. Human papillomavirus testing by polymerase chain reaction in situ hybridization and reverse-transcribed polymerase chain reaction in situ was negative in each case, compared with a detection rate of 107 of 108 (99%) for squamous intraepithelial lesion-associated cervical squamous cell and adenocarcinomas. Two of the women died of extensive local recurrence; two other women were recently diagnosed. We conclude that highly differentiated keratinizing squamous cell carcinoma of the cervix is a rare entity not associated with human papillomavirus infection or squamous intraepithelial lesion and thus difficult to detect on routine cervical cancer screening.

Compared with computed tomography (CT) and magnetic resonance imaging (MRI), positron emission tomography (PET) may have additional value in the assessment of primary and recurrent cervical cancer. However, the degree of tumour uptake of {sup 18}F-2-fluoro-2-deoxy-d-glucose (FDG) uptake is sometimes influenced by diabetes mellitus (DM). Therefore, we conducted this prospective study to compare the diagnostic ability of FDG-PET in patients with cervical cancer complicated by DM and those without DM. Patients with untreated locally advanced primary or clinically curable recurrent cervical carcinoma were enrolled. Both FDG-PET and MRI/CT scans were performed within 2 weeks. Patients were categorised into the following groups: hyperglycaemic DM (fasting blood sugar >126 mg/dl), euglycaemic DM and non-DM. The lesions were confirmed histologically or by clinical follow-up. The receiver operating characteristic curve method, with calculation of the area under the curve (AUC), was used to evaluate the discriminative power. From February 2001 to January 2003, 219 patients (75 with primary and 144 with recurrent cervical cancer) were eligible for analysis. Sixteen had hyperglycaemic DM, 12 had euglycaemic DM and 191 were in the non-DM group. The diagnostic power of PET in the hyperglycaemic DM, euglycaemic DM and non-DM groups did not differ significantly with regard to the identification of either metastatic lesions (AUC, 0.967/0.947/0.925, P>0.05) or primary tumours/local recurrence (AUC, 0.950/0.938/0.979, P>0.05). Considering all DM patients, PET showed a significantly higher detection power than MRI/CT scans in respect of metastatic lesions (AUC=0.956 vs 0.824, P=0.012). In comparison with its accuracy in non-DM patients, the accuracy of PET in cervical cancer patients with mild to moderate DM was not significantly reduced. (orig.)

proposed method showed that the areas under the receiver operating characteristic curve (AUCs of PAX1 were 0.833, 0.742, and 0.739 for the detection of cervical intraepithelial neoplasms grade 2 and worse lesions (CIN2+, cervical intraepithelial neoplasms grade 3 and worse lesions (CIN3+, and squamous cell carcinoma, respectively. The sensitivity and specificity for detecting CIN2+ lesions were 0.941 and 0.600, respectively, with a cutoff value of 31.27%. The proposed method also showed superior sensitivity over qMSP methods for the detection of CIN2+ and CIN3+ (0.941 vs 0.824 and 1.000 vs 0.800, respectively. Furthermore, the novel method exhibited higher AUC (0.833 for the detection of CIN2+ than qMSP (0.807. Conclusion: The results of thiol-labeled AuNP method were clearly observed by the naked eyes without requiring any expensive equipment. Therefore, the thiol-labeled AuNP method could be a simple but efficient strategy for cervical cancer screening.

There is currently limited information about human papillomavirus (HPV) genotype distribution in women in the South Pacific region. This study's objective was to determine HPV genotypes present in cervical cancer (CC) and precancers (cervical intraepithelial lesion (CIN) 3) in Fiji. Cross-sectional analysis evaluated archival CC and CIN3 biopsy samples from 296 women of Melanesian Fijian ethnicity (n=182, 61.5%) and Indo-Fijian ethnicity (n=114, 38.5%). HPV genotypes were evaluated using the INNO-LiPA assay in archival samples from CC (n=174) and CIN3 (n=122) among women in Fiji over a 5-year period from 2003 to 2007. Overall, 99% of the specimens tested were HPV DNA-positive for high-risk genotypes, with detection rates of 100%, 97.4% and 100% in CIN3, squamous cell carcinoma (SCC) and adenosquamous carcinoma biopsies, respectively. Genotypes 16 and 18 were the most common (77%), followed by HPV 31 (4.3%). Genotype HPV 16 was the most common identified (59%) in CIN3 specimens, followed by HPV 31 (9%) and HPV 52 (6.6%). Multiple genotypes were detected in 12.5-33.3% of specimens, depending on the pathology. These results indicated that the two most prevalent CC-associated HPV genotypes in Fiji parallel those described in other regions worldwide, with genotype variations thereafter. These data suggest that the currently available bivalent and quadrivalent HPV vaccines could potentially reduce cervical cancers in Fiji by over 80% and reduce precancers by at least 60%.

Full Text Available 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.

Given the importance of epidemiological studies on the prevalence of human papilloma virus (HPV) and its subtypes to plan more effective strategies for cervical cancer prevention, the aim of this study was to determine the prevalence of HPV in women with cervical intraepithelial neoplasia and cancer in Isfahan. In this descriptive cross-sectional study, women referred to oncology clinic of Shahid Beheshti Hospital because of abnormal cytology of their cervices within the last year were studied. The 2001 Bethesda system was used for histologic classification. The distribution of different pathologies was as follows: squamous cell carcinoma (SCC) 34.7%, low-grade squamous intraepithelial lesions (LSIL) 30.5%, high-grade squamous intraepithelial lesions (HSIL) 22.8%, atypical squamous cell of undetermined significance (ASCUS) 8.4%, and adenocarcinoma (AC) 3.3%. There was no case of atypical glandular of undetermined significance or cases of adenocarcinoma associated with an early lesion. The presence of HPV infection and its subtypes including HPV 16, 18, 6 and 11 was assessed in different cytological categories of cervical neoplasia, by using polymerase chain reaction method. During this study, 130 patients were studied. Their median age was 52 years (range 29-73 years). HPV was detected in 118/130 patients (90.8%) with abnormal cervical cytology. The prevalence of positive HPV samples was 97.6, 80, 93.1, 92.3, and 66.6% in cases with SCC, AC, HSIL, LSIL, and ASCUS, respectively (P prevalence of HPV type 16 was not significantly different in various cytological categories of cervical neoplasia (P > 0.05). The prevalence of HPV type 16 and 18 was significantly higher than the HPV type 11 or 6 in cervical neoplastic lesions (P prevalence of HPV infection in all categories of cervical neoplasia. This emphasizes the importance of HPV screening and vaccination programs. In order to assess more effective screening programs in Isfahan and evaluate the cost-effectiveness of

In cervical carcinomas, high-risk human papillomavirus (HR-HPV) may be integrated into host chromosomes or remain extra-chromosomal (episomal). We used the W12 cervical keratinocyte model to investigate the effects of HPV16 early gene depletion on in vitro cervical carcinogenesis pathways, particularly effects shared by cells with episomal versus integrated HPV16 DNA. Importantly, we were able to study the specific cellular consequences of viral gene depletion by using short interfering RNAs known not to cause phenotypic or transcriptional off-target effects in keratinocytes. We found that while cervical neoplastic progression in vitro was characterized by dynamic changes in HPV16 transcript levels, viral early gene expression was required for cell survival at all stages of carcinogenesis, regardless of viral physical state, levels of early gene expression or histology in organotypic tissue culture. Moreover, HPV16 early gene depletion induced changes in host gene expression that were common to both episome-containing and integrant-containing cells. In particular, we observed up-regulation of autophagy genes, associated with enrichment of senescence and innate immune-response pathways, including the senescence-associated secretory phenotype (SASP). In keeping with these observations, HPV16 early gene depletion induced autophagy in both episome-containing and integrant-containing W12 cells, as evidenced by the appearance of autophagosomes, punctate expression of the autophagy marker LC3, conversion of LC3B-I to LC3B-II, and reduced levels of the autophagy substrate p62. Consistent with the reported association between autophagy and senescence pathways, HPV16 early gene depletion induced expression of the senescence marker beta-galactosidase and increased secretion of the SASP-related protein IGFBP3. Together, these data indicate that depleting HR-HPV early genes would be of potential therapeutic benefit in all cervical carcinogenesis pathways, regardless of viral

The objective of this study was to review the literature on the epidemiological association between human papillomavirus (HPV), HIV, and cervical neoplasia, and the impact of highly active antiretroviral therapy (HAART) on this association. MEDLINE was searched using the terms 'human papillomavirus', 'HPV', 'HIV', 'cervix', 'neoplasm', and 'antiretroviral' to identify articles published before December 2006. HIV-infection was strongly associated with a higher prevalence, incidence, and persistence of HPV infection and correlated with prevalence, incidence, persistence, and progression of squamous intraepithelial lesions. The association between HIV and invasive cervical carcinoma has been more difficult to establish, but is now fully recognized. HAART seems to have little, if any, beneficial effect on the natural history of intraepithelial lesions in HIV-positive women. Despite this fact, HAART, does increase the life expectancy of HIV-positive women. Therefore, it remains important to closely monitor HPV-related disease in women with HIV who are receiving HAART, particularly in regions of the world where cervical screening is not available routinely.

In response to antigen naive CD8+, T cells differentiate into effector cells, which express Natural killer (NK) receptors, lose CD28 expression, and die by apoptosis. However, in smaller quantities, the cells are retained for subsequent exposure to the same antigen. Knowledge is limited regarding whether the percentages of CD28-, Effector memory (EMRA(null/dim)), and the CD16+/CD56 + CD8+ T cells of women with low-grade cervical lesions are altered at a systemic level. We enrolled in this study women controls and women with Human papilloma virus infection (HPV-I) without associated cellular neoplastic changes and with Cervical Intraepithelial Neoplastic-I (CIN-I). Flow cytometry (FC) was performed for measurement of CD28-, memory subset, and NK-like CD8 + T cells, and IL-17, IFN-gamma, Tumor necrosis factor (TNF)-alpha, Interleukin (IL)-10, IL-6, IL-4, and IL-2. Finally, we genotyped the HPV. The CIN-I group increased the CD8 + CD28- and CD16+/56+ T cell percentage compared with that of HPV-I and controls (p levels among all groups. Increased levels of CD28-, EMRA(null/dim), and CD16+/CD56 + CD8+ T cells of peripheral blood in women with CIN-I may be associated with persistent HPV infection and could exert an influence on progression to cervical cancer.

Paraneoplastic neurological syndromes are rare, and although they are frequently associated with gynecological malignancies, cervical cancer is a rare cause. The symptoms of anti-Ma2 encephalitis are diverse and often present prior to the diagnosis of malignancy. We report a case of a 37-year-old woman with a history of cervical cancer presenting with unexplained weight gain and vertical supranuclear gaze palsy. Magnetic resonance imaging of the brain revealed lesions within the bilateral hypothalami and midbrain. Anti-Ma2 antibodies were eventually found in the serum, prompting a search for malignancy. Recurrent metastatic cervical cancer was found in the retroperitoneal lymph nodes. This is the first report of cervical cancer in association with anti-Ma2 encephalitis, and highlights the need for a high degree of suspicion in patients with a cancer history presenting with neurological symptoms. The symptoms associated with anti-Ma2 encephalitis are diverse and typically precede the diagnosis of cancer in patients, and should trigger a search for an underlying malignancy.

To evaluate the performance of an automated DNA-image-cytometry system as a tool to detect cervical carcinoma. Of 384 liquid-based cervical cytology samples with available biopsy follow-up were analyzed by both the Imager System and a high-risk HPV test (Cobas). The sensitivity and specificity of Imager System for detecting biopsy proven high-grade squamous intraepithelial lesion (HSIL, cervical intraepithelial neoplasia [CIN]2-3) and carcinoma were 89.58% and 56.25%, respectively, compared to 97.22% and 23.33% of HPV test but additional HPV 16/18 genotyping increased the specificity to 69.58%. The sensitivity and specificity of the Imager System for predicting HSIL+ (CIN2-3+) lesions among atypical squamous cells of undetermined significance samples were 80.00% and 70.53%, respectively, compared to 100% and 11.58% of HPV test whilst the HPV 16/18 genotyping increased the specificity to 77.89%. Among atypical squamous cells-cannot exclude HSIL, the sensitivity and specificity of Imager System for predicting HSIL+ (CIN2-3+) lesions upon follow up were 82.86% and 33.33%%, respectively, compared to 97.14% and 4.76% of HPV test and the HPV 16/18 genotyping increased the specificity to 19.05%. Among low-grade squamous intraepithelial lesion cases, the sensitivity and specificity of the Imager System for predicting HSIL+ (CIN2-3+) lesions were 66.67% and 35.71%%, respectively, compared to 66.67% and 29.76% of HPV test while HPV 16/18 genotyping increased the specificity to 79.76%.

To evaluate the impact of policies for removing women before the recommended age of 64 from screening programmes for cervical cancer in the United Kingdom. A mathematical model of the clinical course of precancerous lesions which accounts for the influence of infection with the human papillomavirus, the effects of screening on the progression of disease, and the accuracy of the testing procedures. Two policies are compared: one in which women are withdrawn from the programme if their current smear is negative and they have a recent history of regular, negative results and one in which women are withdrawn if their current smear test is negative and a simultaneous test is negative for exposure to high risk types of human papillomavirus. United Kingdom cervical screening programme. The incidence of invasive cervical cancer and the use of resources. Early withdrawal of selected women from the programme is predicted to give rise to resource savings of up to 25% for smear tests and 18% for colposcopies when withdrawal occurs from age 50, the youngest age considered in the study. An increase in the incidence of invasive cervical cancer, by up to 2 cases/100 000 women each year is predicted. Testing for human papillomavirus infection to determine which women should be withdrawn from the programme makes little difference to outcome. This model systematically analyses the consequences of screening options using available data and the clinical course of precancerous lesions. If further audit studies confirm the model's forecasts, a policy of early withdrawal might be considered. This would be likely to release substantial resources which could be channelled into other aspects of health care or may be more effectively used within the cervical screening programme to counteract the possible increase in cancer incidence that early withdrawal might bring.

Full Text Available Introduction: Despite increasing awareness related to sexual health for cervical cancer survivors, health care providers are passive in addressing their sexual issues. The objectives were to develop and investigate the effect of a sexual nursing intervention packet to mitigate sexual dysfunction among cervical cancer survivors. Method: A sample of 104 survivors were participated consecutively based on required inclusive criteria in this quasi-experimental study. The sexual nursing intervention packet focused on the physical, psychological, and care of relational aspects of sexual health elements. The packet consisted of 6 weekly 2-hour sessions. Results: The participants reported poor sexual satisfaction and sexual function. There were no statistically signi fi cant differences in sexual interest, sexual arousal, orgasm, and vaginal lubrication improvement following the intervention, although all the variables in the intervention group were improved clinically. The sexual nursing intervention packet was effective in increasing sexual satisfaction and decreasing dispareunia among cervical cancer survivors. Discussion: This study suggests that the quality of life in cervical cancer survivors could be improved with the sexual nursing intervention packet provided as part of supportive group care. This program may be more effective if delivered earlier and for a longer period. Implications for Practice: The sexual nursing intervention packet offers an opportunity to facilitate small-group dynamics that lay the ground for further contacts leading to earlier recognition of sexual problems and active involvement for sexual health improvement for cervical cancer survivors and nurses. It could be utilized for survivor education or support groups to increase sexual satisfaction following cancer treatment.

To evaluate a potential correlation of the maximum standard uptake value (SUVmax) and the minimum apparent diffusion coefficient (ADCmin) in primary and recurrent cervical cancer based on integrated PET/MRI examinations. 19 consecutive patients (mean age 51.6 years; range 30-72 years) with histopathologically confirmed primary cervical cancer (n = 9) or suspected tumor recurrence (n = 10) were prospectively enrolled for an integrated PET/MRI examination. Two radiologists performed a consensus reading in random order, using a dedicated post-processing software. Polygonal regions of interest (ROI) covering the entire tumor lesions were drawn into PET/MR images to assess SUVmax and into ADC parameter maps to determine ADCmin values. Pearson's correlation coefficients were calculated to assess a potential correlation between the mean values of ADCmin and SUVmax. In 15 out of 19 patients cervical cancer lesions (n = 12) or lymph node metastases (n = 42) were detected. Mean SUVmax (12.5 ± 6.5) and ADCmin (644.5 ± 179.7 × 10(-5) mm2/s) values for all assessed tumor lesions showed a significant but weak inverse correlation (R = -0.342, p correlation between SUVmax and ADCmin (R = -0.692, p correlation. These initial results of this emerging hybrid imaging technique demonstrate the high diagnostic potential of simultaneous PET/MR imaging for the assessment of functional biomarkers, revealing a significant and strong correlation of tumor metabolism and higher cellularity in cervical cancer lesions.

Background Cervical cancer is a major public health problem in resource-limited settings, particularly among HIV-infected women. Given the challenges of cytology-based approaches, the efficiency of new screening programs need to be assessed. Setting Community and hospital-based clinics in Gaborone, Botswana. Objective To determine the feasibility, and efficiency of the “See and Treat” approach using Visual Inspection Acetic Acid (VIA) and Enhanced Digital Imaging (EDI) for cervical cancer prevention in HIV-infected women. Methods A two-tier community-based cervical cancer prevention program was implemented. HIV-infected women were screened by nurses at the community using the VIA/EDI approach. Low-grade lesions were treated with cryotherapy on the same visit. Women with complex lesions were referred to our second tier, specialized clinic for evaluation. Weekly quality control assessments were performed by a specialist in collaboration with the nurses on all pictures taken. Results From March 2009 through January 2011, 2,175 patients were screened for cervical cancer at our community-based clinic. 253 (11.6%) were found to have low-grade lesions and received same-day cryotherapy. 1,347 (61.9%) women were considered to have a normal examination and 575 (27.3%) were referred for further evaluation and treatment. Of the 1,347 women initially considered to have normal exams, 267 (19.8%) were recalled based on weekly quality control assessments. 210 (78.6%) of the 267 recalled women and 499 (86.8%) of the 575 referred women were seen at the referral clinic. Of these 709 women, 506 (71.4%) required additional treatment. Overall, 264 CIN stage 2 or 3 were identified and treated, and six micro-invasive cancers identified were referred for further management. Conclusions Our “See and Treat” cervical cancer prevention program using the VIA/EDI approach is a feasible, high-output and high-efficiency program, worthy of considering as an additional cervical cancer

American football is a high-energy contact sport that places players at risk for cervical spine injuries with potential neurological deficits. Advances in tackling and blocking techniques, rules of the game and medical care of the athlete have been made throughout the past few decades to minimize the risk of cervical injury and improve the management of injuries that do occur. Nonetheless, cervical spine injuries remain a serious concern in the game of American football. Injuries have a wide spectrum of severity. The relatively common 'stinger' is a neuropraxia of a cervical nerve root(s) or brachial plexus and represents a reversible peripheral nerve injury. Less common and more serious an injury, cervical cord neuropraxia is the clinical manifestation of neuropraxia of the cervical spinal cord due to hyperextension, hyperflexion or axial loading. Recent data on American football suggest that approximately 0.2 per 100,000 participants at the high school level and 2 per 100,000 participants at the collegiate level are diagnosed with cervical cord neuropraxia. Characterized by temporary pain, paraesthesias and/or motor weakness in more than one extremity, there is a rapid and complete resolution of symptoms and a normal physical examination within 10 minutes to 48 hours after the initial injury. Stenosis of the spinal canal, whether congenital or acquired, is thought to predispose the athlete to cervical cord neuropraxia. Although quite rare, catastrophic neurological injury is a devastating entity referring to permanent neurological injury or death. The mechanism is most often a forced hyperflexion injury, as occurs when 'spear tackling'. The mean incidence of catastrophic neurological injury over the past 30 years has been approximately 0.5 per 100,000 participants at high school level and 1.5 per 100,000 at the collegiate level. This incidence has decreased significantly when compared with the incidence in the early 1970s. This decrease in the incidence of

Loss of Dependence on Continued Expression of the Human Papillomavirus 16 E7 Oncogene in Cervical Cancers and Precancerous Lesions Arising in Fanconi Anemia Pathway-Deficient Mice

Full Text Available 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.

Full Text Available OBJECTIVES: Cervical cancer is the leading cause of cancer death among women in developing countries. This study was designed to evaluate whether visual inspection with acetic acid and magnification (VIAM improved confirmation of cervical lesions as compared to confirmation with visual inspection with acetic acid (VIA without magnification when used by physicians. METHODS: From April-December 2004, women in San Martin, Peru, who were referred as VIA-positive by an "obstetriz" (a professional midwife with 6 years of university training were randomized into two groups for confirmatory screening by a physician using either VIA or VIAM with an AviScope,TM a hand-held 4x magnification scope with a green light source. The reference standard for the presence or absence of cervical neoplasia was colposcopy and directed biopsy, as required. RESULTS: A total of 358 women participated in the study; 161 had a confirmatory examination with VIAM and 159 with VIA. Sensitivity for low- or high-grade lesions was 68% with VIA and 77% with VIAM, and specificity was 62% with VIA and 63% with VIAM; however, these differences were not statistically significant. CONCLUSIONS: For settings where physician confirmation of cervical abnormalities identified through visual inspection is required and available, this study demonstrates that VIAM had no significant advantage over VIA.

The purpose of this study was to determine the clinical value of a semiquantitative measure of human papillomavirus viral load by the hybrid capture 2 assay for stratification of the risk of histologic cervical intraepithelial neoplasia grade 3 or carcinoma. The Atypical Cells of Unknown Significance and Low-Grade Squamous Intraepithelial Lesions Triage Study was a randomized clinical trial of 5060 women with 2 years of follow-up to evaluate treatment strategies for women with equivocal or mildly abnormal cervical cytologic condition. The usefulness of the continuous hybrid capture 2 output relative light units/positive controls that were above the positive threshold (1.0 relative light units/positive controls), which was a surrogate for human papillomavirus viral load, for distinguishing between hybrid capture 2 positive women who were diagnosed with cervical intraepithelial neoplasia grade 3 or carcinoma during the study from those who were not diagnosed with cervical intraepithelial neoplasia grade 3 or carcinoma was examined with the use of receiver-operator characteristic analyses. Relative light units/positive controls values did not further discriminate between hybrid capture 2 positive women with cervical intraepithelial neoplasia grade 3 or carcinoma from those with less than cervical intraepithelial neoplasia grade 3 or carcinoma. The use of a cervical intraepithelial neoplasia grade 2 or more severe or carcinoma case definition did not alter our findings. Among women with atypical cells of unknown significance or low-grade squamous intraepithelial lesion cervical cytologic findings, the hybrid capture 2 viral load measurement did not improve the detection of 2-year cumulative cases of cervical intraepithelial neoplasia grade 3 or carcinoma significantly.

Sialyltransferase gene expression is altered in several cancers, including examples in the cervix. Transcriptional regulation of the responsible genes depends on different promoters. We aimed to determine the association of single-nucleotide polymorphisms in the B3 promoter of the ST3GAL4 gene and the P1 promoter of the ST6GAL1 gene with cervical premalignant lesions or cervical cancer. A blood sample and/or cervical scrapes were obtained from 104 women with normal cytology, 154 with premalignant lesions and 100 with cervical cancer. We also included 119 blood samples of random donors. The polymorphisms were identified by sequencing from PCR products. For the B3 promoter, a fragment of 506 bp (from nucleotide -408 to +98) was analyzed, and for the P1 promoter a 490 bp (-326 to +164) fragment. The polymorphism analysis showed that at SNP rs10893506, genotypes CC and CT of the ST3GAL4 B3 promoter were associated with the presence of premalignant lesions (OR=2.89; 95%CI 1.72-4.85) and cervical cancer (OR=2.23; 95%CI 1.27-3.91). We detected only one allele of each polymorphism in the ST6GAL1 P1 promoter. We did not detect any genetic variability in the P1 promoter region in our study population. Our results suggest that the rs10893506 polymorphism -22C/T may increase susceptibility to premalignant and malignant lesions of the cervix.

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

ABSTRACT Objectives The study of cervical muscles and their significance in the development and perpetuation of Temporomandibular Disorders has not been elucidated. Thus this project was designed to investigate the association between cervical musculoskeletal impairments and Temporomandibular Disorders. Material and Methods A sample of 154 subjects participated in this study. All subjects underwent a series of physical tests and electromyographic assessment (i.e. head and neck posture, maximal cervical muscle strength, cervical flexor and extensor muscles endurance, and cervical flexor muscle performance) to determine cervical musculoskeletal impairments. Results A strong relationship between neck disability and jaw disability was found (r = 0.82). Craniocervical posture was statistically different between patients with myogenous Temporomandibular Disorders (TMD) and healthy subjects. However, the difference was too small (3.3º) to be considered clinically relevant. Maximal cervical flexor muscle strength was not statistically or clinically different between patients with TMD and healthy subjects. No statistically significant differences were found in electromyographic activity of the sternocleidomastoid or the anterior scalene muscles in patients with TMD when compared to healthy subjects while executing the craniocervical flexion test (P = 0.07). However, clinically important effect sizes (0.42 - 0.82) were found. Subjects with TMD presented with reduced cervical flexor as well as extensor muscle endurance while performing the flexor and extensor muscle endurance tests when compared to healthy individuals. Conclusions Subjects with Temporomandibular Disorders presented with impairments of the cervical flexors and extensors muscles. These results could help guide clinicians in the assessment and prescription of more effective interventions for individuals with Temporomandibular Disorders. PMID:24422022

Full Text Available OBJECTIVES: Precancerous and cancerous cells can trigger an immune response that may limit tumor development and can be used as a prognostic marker. The aims of the present study were to quantify the presence of B and T lymphocytes, macrophages and cells expressing inducible nitric oxide synthase (iNOS in the cervical stroma of women with grade III cervical intraepithelial neoplasia (CIN III or in the intratumoral and peritumoral tissue of women with stage I invasive carcinoma. METHODS: Cervical tissue specimens were obtained from 60 women (20 each from control tissues, CIN III and invasive carcinomas. The average ages in the control, CIN III and invasive groups were 43.9 (± 4.3, 35.5 (± 9.5, and 50 (± 11.2 years, respectively. The specimens were immunohistochemically labeled with antibodies to identify T lymphocytes (CD3, cytotoxic lymphocytes (CD8, B lymphocytes (CD20, macrophages (CD68 and iNOS. We evaluated the markers in the stroma above the squamocolumnar junction (control, at the intraepithelial lesion (CIN cases, and in the nfiltrating tumor. Two independent observers performed the immunohistochemical analysis. RESULTS: T lymphocytes, B lymphocytes, macrophages and iNOS were present more frequently (P<0.05 in the stroma of peritumoral invasive tumors compared to the controls and intratumoral invasive cancer samples. CD3+ and CD20+ lymphocytes were present more frequently in CIN III patients compared to samples from patients with intratumoral invasive cancer (P<0.05. CONCLUSION: High numbers of T and B lymphocytes, macrophages and iNOS-expressing cells in the peritumoral stroma of the invasive tumors were observed. Cell migration appeared to be proportional to the progression of the lesion.

The purpose of this investigation was to establish an international baseline of the quantity of physical therapist education on temporomandibular disorders (TMD) during post-professional Orthopedic Manual Physical Therapy (OMPT) education. An electronically distributed survey was sent to programs and data analyzed for trends, including a comparison of TMD and cervical spine disorders education. Current data were compared to pre-existing data from the United States. For the current data-set, the Mann-Whitney U test demonstrated statistical significance when comparing TMD and cervical spine disorders education for both the hours of didactic training provided ( p  didactic ( p  didactic ( p  = 0.23) or clinical education ( p  = 0.15) of cervical spine topics. These data again indicate a lack of uniformity between post-professional training programs in OMPT with respect to TMD education. There is, however, consistency in that most programs provided more training on cervical spine disorders than TMD. Based on these findings, further investigations are appropriate to determine if TMD education is adequate during post-professional OMPT education.

To identify the best available evidence for the effect of toothbrushing on the initiation and progression of gingival recession and non-carious cervical lesions (NCCLs). A protocol was developed for the questions: Does traumatic toothbrushing, compared to normal toothbrushing, lead to an increased prevalence of non-inflammatory gingival recession? [FQ1] and NCCLs? [FQ2]. The search covered four electronic databases. Bibliographies of review articles, relevant texts, World and European Workshops were screened. Hand searches were performed of the Journals of Clinical Periodontology, Periodontology, Periodontal Research and IADR abstracts. A meta-analysis included 159 subjects and showed that subjects who used MTBs (manual toothbrush) had greater gingival recession after 12 months when compared with those using PTBs (powered toothbrush). Thirteen cross-sectional studies identified the most frequent toothbrushing factors associated with gingival recession as being toothbrushing frequency, a horizontal or scrub toothbrushing method, bristle hardness, toothbrushing duration and the frequency of changing a toothbrush. The principal toothbrushing factors associated with NCCLs were toothbrushing method and frequency. The data to support or refute the association between toothbrushing and gingival recession and NCCLs remain largely inconclusive. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Thymidine kinase 1 (TK1) is a proliferation biomarker that has been found useful for prognostication in cancer patients. Here we investigate for the first time the use of TK1 expression as a prognostic factor for patients with premalignant and malignant lesions of the uterine cervix. TK1 expression was determined by immunohistochemistry in cervical lesions (cervical intraepithelial neoplasia (CIN), n = 216; invasive cervical carcinoma, n = 84). TK1 and Ki-67 expressions and pathological/FIGO stages and age were correlated with 5-year survival by Kaplan-Meier, log rank and COX hazard uni- and multivariate analyses. TK1 labeling index (LI) was significantly correlated with CIN grades and invasive cervical carcinoma stages, while TK1 labeling intensity was only correlated to CIN grades. TK1 LI was significantly higher compared with Ki-67 LI. TK1 LI correlated significantly to 5-year survival in patients with invasive cervical carcinoma, particularly nuclear TK1 LI. In a multivariate analysis, nuclear TK1 expression was independent prognostic factor in patients with in situ/invasive cervical carcinoma or in invasive cervical carcinoma alone. Interestingly, in invasive cervical carcinoma patients with advanced tumors, nuclear TK1 expression could identify patients with significantly better survival rates (80%), while Ki-67 could not. Nuclear TK1 expression in early grade CIN predicts risk for progression to malignancy. Nuclear TK1 expression is also a prognostic factor for treatment outcome, particularly in patients with advanced cervical carcinomas. Nuclear TK1 expression is more useful than Ki-67 and pathological/FIGO stages

The purpose of this study is to describe the angiographic findings of collateral vessels in cervicofacial vascular lesions with previously ligated carotid arteries and to evaluate the extent of angiographic assessment needed before embolization. We retrospectively reviewed 10 cervicofacial vascular lesions with previously ligated carotid artery, which were 6 cases of arteriovenous malformation, 2 cases of carotid cavernous fistula, 1 case of hemangioma and 1 case of arteriovenous malformation with carotid cavernous fistula. The previously ligated arteries are proximal external carotid artery (n = 5), branches of external carotid artery (n = 2) and common carotid artery (n = 3). Common carotid artery or internal carotid artery (n = 9), vertebral artery (n = 5), ipsilateral external carotid artery (n = 4), contralateral external carotid artery (n = 5), costocervical trunk (n = 2), thyrocervical trunk (n = 2) were assessed by conventional angiography. Angiography of both carotid and vertebral arteries was performed in 5 cases. The collateral vascular channels were inferolateral trunk of internal carotid artery (n = 8), vertebral artery (n = 5), contralateral external carotid artery (n = 5), ipsilateral external carotid artery (n = 4), deep cervical artery (n = 2) and ascending cervical artery (n = 1). Embolization were performed in 9 cases with operative cannulation (n = 4), embolization via collateral branches of ipsilateral external carotid artery (n = 1), embolization via collateral branches of contralateral external carotid artery (n = 3) and balloon occlusion via direct puncture (n = 1). The collateral channels in cervicofacial vascular lesions with previously ligated carotid artery were inferolateral trunk of internal carotid artery, contralateral or ipsilateral external carotid artery, vertebral artery, deep cervical artery and ascending cervical artery on angiography. Complete angiographic assessment of possible collateral channels is mandatory for the

Serial changes of magnetic resonance imaging (MRI) of spinal cord lesions in multiple sclerosis (MS) were demonstrated. Two inpatients of MS were followed-up for 8 and 5 months respectively. The first case was a 38-year-old housewife with lesions in upper cervical cord, medulla oblongata and visual nerve. The second case was a 45-year-old man with middle thracic spinal cord and brain stem lesions. Both cases were successfully induced into the remission by peroral prednisolone therapy. In the first case, in early stage of the disease, low signal (in IR method) and high signal (in T 2 -weighted SE method) intensities with enlarged lower dorsal medulla were demonstrated. The second MRI in this case specially in horizontal sections revealed round high intensity lesions (in T 2 -weighted SE) with clear margins, which appeared to push away the normal spinal cord tissue. In the third MRI, T 2 weighted SE revealed localized narrowing in C 2 and C 3 cervical cord, and even no signal lesions in IR method were shown in the central of the spinal cord. The forth and fifth MRI, however, showed almost normally recovered spinal cord and medulla oblongata. In the second case, the first MRI revealed high intensity lesions in the middle thracic spinal cord in T 2 weight SE, and moreover, the spinal cord looked very enlarged. In IR method, localized patchy low intensity lesions were seen in the enlarged spinal cord, but in this case, the MRI demonstrated that localized patchy high intensity lesions without cord swelling in SE remained long after the clinically complete recovery of the disease.

Premalignant and malignant lesions are not uncommon in Pakistani women, especially in the older age-groups This study was conducted to determine the clinicopathological importance of conventional Papanicolaou (Pap) smears for the diagnosis of premalignant and malignant lesions of the cervix. Pap smears of 1000 women were examined from January 2007 to June 2009. Only cases with neoplastic cytology were included. The overall frequency of normal, inadequate, neoplastic, and infective smears was 50%, 1.8%, 10.2%, and 38.3%, respectively. Most of the patients (67%) were in the postmenopausal age-group, with the mean age being 44.7±15.63 years. The commonest clinical signs/symptoms seen among the 102 patients with neoplastic gynecological lesions were vaginal discharge and abnormal bleeding (93/102;(91.2% and 62/102;60.7%). Of the 102 cases with neoplastic lesions 46 patients (45%) had low-grade squamous cell intraepithelial lesions (LSILs), 22 (21.5%) had high-grade squamous cell intraepithelial lesions (HSILs), 14 (13.7%) had squamous cell carcinoma, and 6 (5.8%) showed features of adenocarcinoma. Ten (9.8%) cases showed cytology of atypical squamous cells of undetermined significance (ASCUS) and four (3.9%) cases had atypical glandular cells of undetermined significance (AGUS). We conclude that cervical smear examination is well suited for diagnosing neoplastic disease. It is clear that cervical neoplastic lesions are becoming a problem in Pakistan.

Secondary hyperparathyroidism (SHPT) treatment includes parathyroidectomy and percutaneous ethanol injection therapy (PEIT), which are invasive procedures. The condition in which benign hyperfunctioning parathyroid tissue is distributed throughout the neck and mediastinum is termed parathyromatosis. Here, we present the case of a 51-year-old woman who began hemodialysis in 1986 due to chronic kidney disease of unknown etiology and developed SHPT in 1999. She underwent 6 rounds of PEIT followed by total a parathyroidectomy with partial forearm autotransplantation. Between 2011 and 2013, surgeons removed several nodules from her pulmonary and cervical regions and the transplanted masses from her forearm; all showed hyperplasia but exhibited no histological evidence of malignancy. Damage to the parathyroid capsule after repeated PEITs may cause local cervical recurrence and pulmonary lesions, although distant lesions are extremely rare in SHPT. This case is of interest due to the possible association between PEIT and parathyromatosis and distal lesions. © 2017 International Society for Hemodialysis.

Epigenetic remodeling of cell adhesion genes is a common phenomenon in cancer invasion. This study aims to investigate global methylation of cell adhesion genes in cervical carcinogenesis and to apply them in early detection of cancer from cervical scraping. Genome-wide methylation array was performed on an investigation cohort, including 16 cervical intraepithelial neoplasia 3 (CIN3) and 20 cervical cancers (CA) versus 12 each of normal, inflammation and CIN1 as controls. Twelve members of clustered proto-cadherin (PCDH) genes were collectively methylated and silenced, which were validated in cancer cells of the cervix, endometrium, liver, head and neck, breast, and lung. In an independent cohort including 107 controls, 66 CIN1, 85 CIN2/3, and 38 CA, methylated PCDHA4 and PCDHA13 were detected in 2.8%, 24.2%, 52.9%, and 84.2% (P < 10 −25 ), and 2.8%, 24.2%, 50.6%, and 94.7% (P < 10 −29 ), respectively. In diagnosis of CIN2 or more severe lesion of the cervix, a combination test of methylated PCDHA4 or PCDHA13 from cervical scraping had a sensitivity, specificity, positive predictive value, and negative predictive value of 74.8%, 80.3%, 73%, and 81.8%, respectively. Testing of this combination from cervical scraping is equally sensitive but more specific than human papillomavirus (HPV) test in diagnosis of CIN2 or more severe lesions. The study disclosed a collective methylation of PCDH genes in cancer of cervix and other sites. At least two of them can be promising diagnostic markers for cervical cancer noninferior to HPV

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.)

Congenital cervical bronchogenic cyst: A case report

Directory of Open Access Journals (Sweden)

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.

In a randomized study, we have evaluated the treatment of cervical human papillomavirus (HPV) lesions by CO2 laser vaporization. Fifty patients with abnormal Papanicolaou smears and histological evidence of cervical HPV infection associated or not with cervical intraepithelial neoplasia (CIN) grade...... I were randomized to either a treatment or a control group. The cervical swabs were obtained every 3 months in both groups and examined for HPV type 16 DNA by the polymerase chain reaction. After a follow-up period of 12 months no significant differences were found between the laser treatment...... in their cervical smears at 12 months' follow-up was identical in the two groups, supporting the hypothesis that HPV is a persistent infection during which the virus is widespread in the vaginal epithelium....

"Low-grade squamous intraepithelial lesion (LSIL), cannot exclude high-grade squamous intraepithelial lesion" (LSIL-H) is an increasingly used, equivocal interpretive category in gynecologic cytology. In an effort to evaluate its potential usefulness as a measure of quality assurance, we studied patterns of use of the LSIL-H diagnosis compared with "LSIL" and "high-grade squamous intraepithelial lesion" (HSIL) with corresponding histologic outcomes for 10 cytopathologists in our practice. In our laboratory, while the overall rate of associated cervical intraepithelial neoplasia 2 or greater on histologic follow-up for LSIL-H was intermediate between that of LSIL and HSIL, the outcomes for individual cytopathologists varied widely. Monitoring this particular utilization-outcome data with periodic confidential feedback to individual cytopathologists offers an opportunity for practice improvement within a laboratory and serves as an additional measure of quality assurance. These data may be useful for establishing and/or realigning the diagnostic criteria for this equivocal cytologic interpretation endorsed by a pathology practice.

The early detection of intraepithelial lesions of the cervix, through the periodic examination of cervical cells, has been fundamental for the prevention of invasive cervical cancer and its related mortality. In this report, we summarise the cervical cancer screening activities carried out in Catalonia, Spain, within the National Health System during 2008-2011. The study population covers over two million women resident in the area. The evaluation includes 758,690 cervical cytologies performed on a total of 595,868 women. The three-year coverage of cervical cytology among women aged between 25 and 65 years was 40.8%. About 50% of first screened women with negative results had not returned to the second screening round. The introduction of high-risk human papillomavirus DNA (HPV) detection, as a primary screening cotest with cytology among women over age 40 with a poor screening history, significantly improved the detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+), being far superior to cytology alone. Cotesting did not improve the detection of CIN2+. The use of the HPV test for the triage of atypical squamous cell undetermined significance (ASC-US) improved the selection of women at high risk of CIN2+. Sampling (both cytology and HPV test) was largely performed by midwives (66.7%), followed by obstetricians (23.8%) and nurses (7%). Over half of the centres (54.8%) had full use of online medical records. During the study period, educational activities for professionals and for women were carried out periodically. The organisation of screening as a population activity in which women are actively called to the screening visit and the introduction of HPV testing as a primary screening tool are strongly recommended to ensure the maximum population impact in the reduction of the cervical cancer burden.

It is estimated that 1%-2% of women develop cervical intraepithelial neoplasia grade 2-3 (CIN 2-3) annually worldwide. The prevalence among women living with HIV is higher, at 10%. If left untreated, CIN 2-3 can progress to cervical cancer. WHO has previously published guidelines for strategies to screen and treat precancerous cervical lesions and for treatment of histologically confirmed CIN 2-3. Guidelines were developed using the WHO Handbook for Guideline Development and the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach. A multidisciplinary guideline panel was created. Systematic reviews of randomized controlled trials and observational studies were conducted. Evidence tables and Evidence to Recommendations Tables were prepared and presented to the panel. There are nine recommendations for screen-and-treat strategies to prevent cervical cancer, including the HPV test, cytology, and visual inspection with acetic acid. There are seven for treatment of CIN with cryotherapy, loop electrosurgical excision procedure, and cold knife conization. Recommendations have been produced on the basis of the best available evidence. However, high-quality evidence was not available. Such evidence is needed, in particular for screen-and-treat strategies that are relevant to low- and middle-income countries. Copyright © 2015. Published by Elsevier Ireland Ltd.

In order to study how the efficiency of the halo vest is affected by different lengths of the vest, an experimental headband was devised that allowed the head of a normal person to be held securely in the halo attachment. The vest was then modified to allow it to be adjusted to three different lengths (Fig. 2): a full vest extended to the iliac crests, a short vest extended to the twelfth ribs, and a half vest extended to the level of the nipples. Twenty normal, healthy adult men participated in the study. For each vest length, radiographs were made of each subject demonstrating rotation, flexion-extension, and lateral bending of the cervical spine. There was no rotation of the cervical spine, regardless of the length of the vest. There was a variable degree of motion in flexion or extension of the upper part of the cervical spine with all vest lengths, but this was not statistically significant. There was definite increase of motion caudad to the level of the fifth cervical vertebra regardless of the length of the vest. We concluded that a lesion of the upper part of the cervical spine can be treated effectively by halo traction with a half vest. This will improve the comfort and care of the patient and avoid the necessity of removing the vest if emergency cardiovascular resuscitation is needed. In the treatment of lesions of the lower part of the cervical spine (caudad to the level of the fourth cervical vertebra), the use of a halo vest that extends caudad to the level of the twelfth ribs does provide additional stability.
