Full Text Available Introduction: The infections of female genital tract, especially the cervix are asymptomatic in presentation and pose a diagnostic challenge. Vaginal infections can lead to cytoplasmic and nuclear abnormalities in the epithelial cells. Additionally, these infections could augur an inflammatory response of varying nature. The most common flora include Candida albicans, Gardnerella vaginalis, Trichomonas vaginalis, Human Papilloma Virus (HPV, Human Herpes Virus (HHV and Actinomyces sp. Aim: This study seeks to measure the role of Papanicolaou smear in detection of pathologic flora: Candida albicans, Gardnerella vaginalis, Trichomonas vaginalis, HPV, HHV and Actinomyces; in a rural health care set up amongst women in the reproductive and menopausal age group. Materials and Methods: A retrospective study of cervical smears by Papanicolaou method, over a 14 month period was carried out in a tertiary care centre including a total number of 150 patients. Results: Of the total of 150 samples examined, Candida species was the most frequently detected (8.7% followed by Trichomonas vaginalis (5.3% and Gardnerella vaginalis species (4.7%. HPV-induced changes were noted in a mere 2% of cases. Actinomyces species was noted in less than 1% of cases. Conclusion: The Papanicolaou test for examining cervical smear has definite uses in detecting vaginal microorganisms. Apart from detection of the usual pathogenic flora, the test has utility in defining the degree of inflammation and additional reparative changes.

The PAPNET System is the only device with a neural-network-based-artificial intelligence to detect and show the images of abnormal cells on the monitor to be evaluated in an interactive way. We effectively used the PAPNET in rescreening of conventional cervical smears and we detected its advantages and its disadvantages. In this paper, we report our results from PAPNET-assisted primary screening performed on 20,154 conventional smears. The smears were classified as Negative or as Review. The Negative cases were rapidly rescreened mainly near the coverslip edges, which are the slide areas not analyzed by automated devices because of focusing problems. The Review cases were fully reanalyzed by the optic microscope. In summary, 140 positive smears were detected: 57 cases showed changes due to HPV, 63 LSIL, 15 HSIL, and 5 carcinomas. Therefore, the PAPNET System was confirmed as useful in primary screening of conventional cervical samples as well as rescreening.

Full Text Available OBJECTIVE: The purpose of this paper is to describe some of the results of the Morelos HPV Study. The main objective of the Morelos HPV Study is to evaluate the use of human papillomavirus (HPV DNA testing, as compared to the Papanicolaou (Pap test, for cervical cancer (CC screening. MATERIAL AND METHODS: The Morelos HPV Study is currently being conducted in Mexico, to examine the possibility of using HPV testing for CC screening. The HPV testing of self-collected vaginal and clinician-collected cervical specimens was evaluated as part of this study. The acceptability of the HPV testing of self-collected specimens was compared to that of the Pap test. A cost-effectiveness analysis (CEA and cost-benefit analysis (CBA was also performed. RESULTS: The Morelos HPV Study results indicate that HPV testing has a greater sensitivity to detect cervical intraepithelial neoplasia (CIN 2/3 and CC than the Pap test. Our results also indicate an over-all lower acceptability of the Pap test as compared to the self-collected procedure. The results of the CEA and CBA indicate that screening women between the ages of 20-80 for CC using some type of HPV testing is always more cost-effective than screening for CC using the Pap test. CONCLUSIONS: Our results suggest that self- and clinician-collected HPV testing could be used in CC prevention programs, as an effective complement or substitute for the Pap test.OBJETIVO: Describir algunos de los resultados del Estudio de VPH en Morelos.

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.

Increasing Cervical Cancer Screening in Underserved Populations.

Science.gov (United States)

Dorsainvil, Merlyn A

The incidence of cervical cancer has declined dramatically due to Papanicolaou smear testing. However, some minority populations continue to suffer with high incidences and/or death rates of cervical cancer, due to lack of screening. This article updates on cervical cancer screening and prevention and discusses cultural impacts on screening. Knowledge deficits disproportionately affect ethnic minority groups and contribute to cancer incidence, whereas lack of healthcare coverage and low socioeconomic status contribute to screening disparities. Although minority women have cultural beliefs and practices that influence screening, recommendation and/or education from a provider often lead to screening.

The aim of this study was to investigate the clinical performance of high risk (HR) HPV E6/E7 mRNA assay in detecting cervical high-grade intraepithelial neoplasia and cancer among women with atypical squamous cells of undetermined significance (ASCUS) Papanicolaou (Pap) smears. A total of 160 patients with ASCUS who underwent HR-HPV DNA assay, HR-HPV E6/E7 mRNA assay and colposcopy biopsy at Third Affiliated Hospital of Zhengzhou University, China, from December 2015 to March 2017, were enrolled. Logistic regression analysis was used to evaluate the relationship between pathological results with clinical biologic factors. Univariate analysis showed that the qualitative results of HR-HPV DNA, qualitative results of HR-HPV E6/E7 mRNA and expression levels of HR-HPV E6/E7 mRNA were risk factors of high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer (all P HPV E6/E7 mRNA was associated with high-grade CIN and cervical cancer (OR = 8.971, 95% CI = 2.572-31.289, P = 0.001). An optimal cut-off value of ≥ 558.26 copies/ml was determined using receiver operating characteristic curve, and specificity of cut-off value were higher than E6/E7 mRNA qualitative assay and DNA qualitative assay. HPV E6/E7 mRNA quantitative assay may be a valuable tool in triage of ASCUS pap smears. A high specificity of E6/E7 mRNA quantitative assay as a triage test in women with ASCUS can be translated into a low referral for colposcopy.

New technologies in cervical cancer precursor detection.

Soler, M E; Blumenthal, P D

The current literature reflects three routes toward improving cervical cancer screening. The first is to improve the test qualities of cytology-based screening. The use of liquid-based cytology and computerized analysis of Papanicolaou tests are examples of attempts at this approach. Secondly, through various combinations of parallel or sequential tests, either the sensitivity or the specificity of a given test could be improved depending on the tests chosen and the order in which they were performed (eg, Papanicolaou test followed by human papillomavirus [HPV] or vice versa). Several excellent studies have been published this year on the use of HPV DNA testing as a primary screening modality and as an adjunct to the triage of mildly abnormal cytologic findings. The recent literature also reflects increasing interest in visual inspection of the cervix and self-collected samples for HPV testing as an equally effective and viable alternative to cytology in low-resource settings. A third possibility is to make use of advances in digital and spectroscopic techniques. In these cost-conscious times, a significant number of articles address the cost-effectiveness of these technologies and the real value of cervical cancer screening. This article reviews the current literature concerning both the advent of new cervical cancer screening technologies and the rediscovery of old ones.

Early detection of cervical cancer improves the chances of successful treatment. The aim of this study was to determine the effect of education about cervical cancer and human papillomavirus on the healthy lifestyle, behavior, and beliefs of Turkish women who were without cancer, using the PRECEDE education model. This qualitative and quantitative study was conducted as a prospective, randomized, 2-group (intervention and control) trial at a community training center in north Turkey. A total of 156 Turkish women who were without cancer participated in this study. The semistructured interview form, the SF-36 Health Status Questionnaire, the Health Belief Model Scale for Cervical Cancer and Pap Smear Test, and the Healthy Lifestyle Behavior Scale II were used. The subdimension scores of the Health Belief Model Scale for Cervical Cancer and Pap Smear Test were found to be higher among women in the study group (cervical cancer seriousness, P = .001; health motivation, P = .001) as compared with the control group after the education program. The SF-36 Health Status Questionnaire domain scores for physical role limitations, mental role limitations, and general health perceptions increased in the study group after the intervention. The posteducation health motivation of women in the study group was improved, the women's perceptions of obstacles to Papanicolaou testing decreased, and through increased knowledge and awareness, the rate of Papanicolaou testing increased. Educational programs aimed at motivating women to increase their awareness of cervical cancer, preventing cervical cancer, and having Papanicolaou testing are necessary and beneficial in this sample.

Molecular techniques for human papillomavirus (HPV) detection have a good performance as screening tests and could be included in cervical cancer early detection programs. We conducted a population-based trial comparing HPV detection and Papanicolaou as primary screening tests, in a public health service in Santiago, Chile. To describe the experience of implementing this new molecular test and present the main results of the study. Women aged 25 to 64 enrolled in three public health centers were invited to participate. In all women, samples were collected for Papanicolaou and HPV DNA testing, and naked-eye visual inspection of the cervix with acetic acid was performed. Women with any positive screening test were referred to the local area hospital for diagnostic confirmation with colposcopy and biopsy of suspicious lesions. Screening results were obtained for 8265 women, of whom 931 (11.3%) were positive to any test. The prevalence of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) was 1.1%; nine women had invasive cervical cancer. Sensitivities for the detection of CIN2+ were 22.1% (95% confidence interval (CI) 16.4-29.2) for Papanicolaou and 92.7% (95% CI 84.4-96.8) for HPV testing; specificities were 98.9% (95% CI 98.7-99.0) and 92.0% (95% CI 91.4-92.6) respectively. This experience showed that the implementation of a molecular test for cervical cancer screening is not a major challenge in Chile: it was well accepted by both the health team and the participants, and it may improve the effectiveness of the screening program.

The Conference was organized to celebrate the 50th anniversary of the cervical smear test, commonly referred to as the `Pap test` after its creator, George Nicholas Papanicolaou. The reports present the development of the test, its worldwide application, and its performance as the screening test for the detection of cervical cancer. Pap smear screening for precursors of carcinoma of the cervix has led to dramatic decrease in the incidence and deaths from this cancer. The test represents one of the greatest achievements in preventive medicine.

To investigate the prevalence of abnormal cervical cytological findings and local risk factors in Ibadan, Nigeria. All women aged ≥15 years in each household in Idikan, Ibadan, were invited to participate in a population-based study. Structured questionnaires were administered to all consenting women. Conventional cervical Papanicolaou smears obtained from sexually active women were classified using the 2001 Bethesda system. The diagnoses were correlated with sociodemographic data and risk factors. Of 2,870 women aged ≥15 years estimated to live in Idikan, 1,204 sexually active women consented to pelvic examination and cervical smears. Results were available for 1,104 women (mean age: 39.8 years). Mean ages at menarche, first sexual intercourse and first pregnancy were 16.1, 20.3 and 20.7 years, respectively. Cytological results were categorized into atypical squamous cells of undetermined significance and atypical glandular cells 22 (1.99%); low-grade 43 (3.89%) and high-grade squamous intraepithelial lesions (HSIL) 17 (1.54%); invasive cancer 2 (0.18%) and normal 593 (53.8%) and reactive changes 427 (38.7%). The prevalence of epithelial abnormalities is 7.6%. Significant host-related factors in those with HSIL and invasive cancer included older age (mean 56.2 years), high parity and gravidity, lack of formal education and being divorced (p prevalence data and local risk factors for abnormal cervical cytology in a Nigerian population, which will be useful for planning future cervical cancer control programs.

The objective of the study was to determine whether the Toyota production system process improves Papanicolaou test quality and patient safety. An 8-month nonconcurrent cohort study that included 464 case and 639 control women who had a Papanicolaou test was performed. Office workflow was redesigned using Toyota production system methods by introducing a 1-by-1 continuous flow process. We measured the frequency of Papanicolaou tests without a transformation zone component, follow-up and Bethesda System diagnostic frequency of atypical squamous cells of undetermined significance, and diagnostic error frequency. After the intervention, the percentage of Papanicolaou tests lacking a transformation zone component decreased from 9.9% to 4.7% (P = .001). The percentage of Papanicolaou tests with a diagnosis of atypical squamous cells of undetermined significance decreased from 7.8% to 3.9% (P = .007). The frequency of error per correlating cytologic-histologic specimen pair decreased from 9.52% to 7.84%. The introduction of the Toyota production system process resulted in improved Papanicolaou test quality.

Full Text Available Introduction: Co-testing performance for detection of high grade Cervical Intraepithelial Neoplasia (CIN has not been adequately addressed from Low Resource Countries (LRCs. Where isolated tests do not have adequate performance, further explorations are recommended. Aim: To evaluate the co-testing of conventional cervical screening tests such as Papanicolaou (Pap and Visual Inspection Cervix with Acetic Acid (VIA, with care HPV on Cervical Samples (CHPV or on Vaginal Samples (VHPV in the detection of high grade CIN. Materials and Methods: The cross-sectional study was conducted on ever married women of age 30 to 59 years in a rural community of Dadri. Women were screened by CHPV, VHPV, and Pap and VIA methods. Confirmation of screen positives was done by histology. Sensitivity, Specificity and likelihood ratios of different combinations of test determined to evaluate the performance. Results: Total eligible women, 66.2% (5032/7604 responded for screening. Analysis was performed on 4658, after excluding those who did not complete all screenings. Co-testing of CHPV (OR=246 or VHPV (OR=278 with Pap had highest association. Positive likelihood ratios of CHPV and VHPV with Pap in CIN II+ detection rates were 13.0 and 11.8 and in CIN III+ the detection rates were 18.0 and 16.0 respectively. Higher sensitivities and specificities were observed in co-testing for CIN III+ detection as against CIN II+ lesions. Conclusion: Choice of co-testing in a pair of tests for detection of high grade CIN is likely to depend on whether screening is targeted for developed or low resource country. VIA in isolation might not yield optimal results for LRCs.

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.

Full Text Available Evidence for the clinical utility of human papillomavirus (HPV DNA testing has increased over the years and has now become very convincing. Some specific uses of HPV detection are a triage of women with cytological determinations of atypical squamous cells of undetermined significance (ASC-US and related management strategies, b as a marker for test of cure post-treatment, and c most importantly, as an adjunct to cytology in routine cervical disease screening programs. There are many studies that support each of these applications and include 8 studies on ASC-US triage, 10 on test of cure and 13 on adjunctive or stand-alone HPV screening. The most notable investigation of ASC-US triage was ALTS, a randomized controlled trial of 3 488 women. With respect to routine HPV screening the combined studies included 77 000 women, providing as a histological endpoint more than 1 000 cases of high-grade cervical intraepithelial neoplasia (CIN or cancer. Testing methods were either the Hybrid Capture 2 (HC2 test or the polymerase chain reaction (PCR test. HPV testing of women with ASC-US cytology had on average a higher sensitivity (90% and specificity (70% than repeating the cytological test (sensitivity 75%, specificity 60% and was also more sensitive than colposcopy for follow-up. As an adjunct to the Papanicolaou (Pap cytology test in routine screening, HPV DNA testing was a more sensitive indicator for prevalent high-grade CIN than either conventional or liquid cytology. A combination of HPV DNA and Papanicolaou testing had almost 100% sensitivity and negative predictive value. The specificity of the combined tests was slightly lower than the specificity of the Papanicolaou test. One "double-negative" HPV DNA and Papanicolaou test indicated a higher prognostic assurance against risk of future CIN 3 than three subsequent negative conventional Papanicolaou tests and may safely allow three-year or longer screening intervals for such low- risk women.

Human papillomavirus (HPV is known to be associated with cervical intraepithelial neoplasia (CIN and cancer. The objective of the present study was to determine the rate of HPV infection among the Bangladeshi women with different grades of CIN and cancer. Methods: Women aged 20 to 55 years, diagnosed as a case of chronic cervicits, cervical intraepithelial neoplasia (CIN or invasive cancer by Papanicolaou (Pap smear and colposcopy directed biopsy were enrolled in the study. High and intermediate risk oncogenic HPV were detected in cervical samples by real time PCR (rt-PCR. Results: Seventy two women with chronic cervicitis and different grades of CIN were included in the study. Out of 72 cases, 28 (38.9% and 44 (61.1% had chronic cervicitis and CIN respectively. Overall, the HPV infection rate was 43.1% (95% CI= 32%-54% among the study population. CIN cases had significantly high (p<0.01 HPV infection (78.6%; 95% CI=60%-89% compared to cases with chronic cervicitis (18.2%; 95% CI=11.1%-34.5%. Women between the age of 20-30 years had the highest positive rate (50.0% followed by 31-40 years age group (43.6%. All CIN grade 2 and 3 had HPV infection. Conclusion: The study showed that HPV was strongly associated with different grades of CIN. Specific HPV types should be determined to find out the most prevalent HPV types among the Bangladeshi women with CIN and cervical cancers. IMC J Med Sci 2016; 10(1: 29-32

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.

We sought to develop and validate a decision-analytic model for the natural history of cervical cancer for the German health care context and to apply it to cervical cancer screening. We developed a Markov model for the natural history of cervical cancer and cervical cancer screening in the German health care context. The model reflects current German practice standards for screening, diagnostic follow-up and treatment regarding cervical cancer and its precursors. Data for disease progression and cervical cancer survival were obtained from the literature and German cancer registries. Accuracy of Papanicolaou (Pap) testing was based on meta-analyses. We performed internal and external model validation using observed epidemiological data for unscreened women from different German cancer registries. The model predicts life expectancy, incidence of detected cervical cancer cases, lifetime cervical cancer risks and mortality. The model predicted a lifetime cervical cancer risk of 3.0% and a lifetime cervical cancer mortality of 1.0%, with a peak cancer incidence of 84/100,000 at age 51 years. These results were similar to observed data from German cancer registries, German literature data and results from other international models. Based on our model, annual Pap screening could prevent 98.7% of diagnosed cancer cases and 99.6% of deaths due to cervical cancer in women completely adherent to screening and compliant to treatment. Extending the screening interval from 1 year to 2, 3 or 5 years resulted in reduced screening effectiveness. This model provides a tool for evaluating the long-term effectiveness of different cervical cancer screening tests and strategies.

Computed tomography (CT) of the cervical spinal column was carried out in 42 patients using a General Electric CT/T of a Toshiba TCT60 Type A scanner. There were 22 cervical disk lesions, 4 spinal neoplasms, 6 narrow spinal canals with or without ossification of posterior longitudinal ligament, 2 syringomyelias, 6 traumas and 2 Arnold-Chiari malformations. In all patients, CT-examination followed conventional spinal X-ray studies. Correlation between the CT and conventional X-ray findings revealed the better diagnostic capability of the CT. For example, the measured midline sagittal diameter of the spinal canal in a patient with the narrowest canal in this series was 7.4 mm on the CT and 9.6 mm on the conventioned plain film at the C/sub 5/ level. To know the precise sagittal diameter of the cord itself, CT myelography (CTM) is indispensable. CTM is useful in determining the nature of the disease, the risk and approach of surgery, and for evaluation after the surgical procedure. Although the range of motion of cervical joints and intervertebral foramen are visible with conventional films, the size and extension of a tumor, the degree of bony errosion and the spinal subarachnoid space can be precisely identified only by CT. CT study of the spine and spinal cord is a simple procedure and less likely to produce complication, even with CTM, although there are certain limitations in the examination which are also presented.

The aim of this study was to assess the prevalence and risk factors predictive of dysplasia among women seen in a gynecologic oncology service with the cytologic diagnosis of atypical squamous cells of undetermined significance (ASCUS) on Papanicolaou smears obtained by the ThinPrep method. Patients with ASCUS ThinPrep Papanicolaou smears seen at the Division of Gynecologic Oncology, University of Vermont, between 1997 and 1999 were identified. The cytologic smears were reviewed and subtyped into reactive or suggestive of squamous intraepithelial lesion (SIL). The charts of these patients were reviewed and the following information was abstracted: age, gravidity, parity, menopausal status, use of hormonal replacement therapy, smoking, history of pelvic cancer, history of radiation therapy, history of abnormal Papanicolaou smear and its treatment, history of human papillomavirus (HPV) infection, and follow-up information including results of repeat Papanicolaou smears, colposcopy, and biopsies. The prevalence of dysplasia was calculated. The demographic features of women with ASCUS, reactive, were compared with those with ASCUS, SIL, using a two-sample t test, chi(2), and Fisher's exact test. Risk factors predictive of dysplasia were calculated using the odds ratio and the 95% confidence interval. P ASCUS on ThinPrep Papanicolaou smear were identified; 63 patients had ASCUS, reactive, and 63 patients had ASCUS, SIL. The demographic features of both groups were similar. The overall prevalence of dysplasia was 15.9% and was significantly higher among women with ASCUS, SIL, than among women with ASCUS, reactive (25.4% versus 6.4%, P = 0.003). The type of ASCUS cytology (reactive versus SIL), smoking, and history of HPV were significant risk factors for dysplasia (P = 0.003, 0.037, and 0. 042, respectively). The prevalence of dysplasia among women seen in a gynecologic oncology service with ASCUS cytology on ThinPrep Papanicolaou smears is 15.9%. Women with ASCUS favor

It is widely accepted that cervical screening has significantly reduced the incidence of cervical cancer worldwide. The primary screening test for cervical cancer is the Papanicolaou (Pap) test, which has extremely variable specificity and sensitivity. There is an unmet clinical need for methods to aid clinicians in the early detection of cervical precancer. Raman spectroscopy is a label-free objective method that can provide a biochemical fingerprint of a given sample. Compared with studies on infrared spectroscopy, relatively few Raman spectroscopy studies have been carried out to date on cervical cytology. The aim of this study was to define the Raman spectral signatures of cervical exfoliated cells present in liquid-based cytology Pap test specimens and to compare the signature of high-grade dysplastic cells to each of the normal cell types. Raman spectra were recorded from single exfoliated cells and subjected to multivariate statistical analysis. The study demonstrated that Raman spectroscopy can identify biochemical signatures associated with the most common cell types seen in liquid-based cytology samples; superficial, intermediate, and parabasal cells. In addition, biochemical changes associated with high-grade dysplasia could be identified suggesting that Raman spectroscopy could be used to aid current cervical screening tests.

Primary human papilloma virus (HPV) screening is more effective than cytology in reducing the risk of cervical cancer, but screening intervals should be extended in HPV-negative women. However, some Markov models predicted that long intervals are associated with an excess risk of cervical cancer. The aim of this analysis was to estimate the real-life risks and benefits of annual Papanicolaou (Pap) screening in HPV-negative women with normal cytology. Women with negative Hybrid Capture 2 (HC2) results and normal cytology at the time of inclusion in the Hannover HPV screening trial underwent annual Pap smears for 5 years. A subgroup was randomly selected for retesting with cytology, HC2, and colposcopy 60–68 months after recruitment. Of 4236 women included, 3406 had at least one Pap smear, but only 1185 attended all five annual screening visits. The proportion of women with at least one abnormal smear was 14.4% in 60 months. The probability of abnormal smears increased continuously over time. No case of ≥ CIN2+ was observed during 5 years. Of 605 women selected for subgroup analysis, 292 agreed to be retested (48.3%). The rate of high-risk HPV at 60–68 months was 3.0% (9/296). The long-term risk of high-grade neoplasia after an initial negative HC2 test and normal cytology result was low, while the rate of false-positive abnormal Pap smears was significant and increased constantly over time. Pap smear screening of HPV-negative women more frequently than every 5 years could be potentially harmful and seems to be of little clinical value

Aim of the study. The purpose of this prospective study was to analyze and compare acute and late side-effects observed in patients with cervical and endometrial cancer treated with conventional 2-dimensional (2D) and conformal 3-dimensional (3D) pelvic radiotherapy. Patients and method. 50 patients treated with conventional pelvic radiotherapy and 50 patients treated with conformal pelvic radiotherapy at the Clinical Department of Gynecological Radiotherapy of the Lower Silesian Oncology Center between November 2004 and October 2005 were entered into a prospective study. We assessed Radiotherapy side-effects according to EORTCIRTOG, performance status according to the WHO, Body Mass Index and hematologic parameters during radiotherapy and one year after treatment. Results. Performance status acc. to the WHO was significantly better in the conformal arm. Anemia and nausea were more frequent in the conventional arm. In both the study groups acute gastrointestinal and genitourinary morbidity was more frequent than late morbidity and performance status was better after than before radiotherapy. Mean BMI was lower after radiotherapy than before treatment. Conclusions. Conformal pelvic radiotherapy in patients with cervical and endometrial cancer is less toxic than conventional pelvic radiotherapy which is also confirmed by the performance status. (authors)

There are few population-based data on the disease burden of cervical cancer from developing countries, especially South Pacific islands. This study aimed to determine the incidence and mortality associated with cervical cancer and the coverage of Papanicolaou (Pap) cervical cytology in 20- to 69-year-old women in Fiji from 2004 to 2007. National data on the incident cases of histologically confirmed cervical cancer and the associated deaths, and on Pap smear results were collected from all pathology laboratories, and cancer and death registries in Fiji from 2004 to 2007. There were 413 incident cases of cervical cancer and 215 related deaths during the study timeframe. The annualised incidence and mortality rates in 20- to 69-year-old Melanesian Fijian women, at 49.7 per 100?000 (95% confidence interval (CI): 43.7-56.4) and 32.3 per 100?000 (95% CI: 26.9-38.4) respectively, were significantly higher than among 20- to 69-year-old Indo-Fijian women at 35.2 per 100?000 (PFiji is high, whereas Pap smear coverage is very low. Greater investment in alternative screening strategies and preventive measures should be integrated into a comprehensive, strategic cervical cancer control program in Fiji.

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.

to evaluate the validity (sensitivity, specificity, and accuracy) of three screening methods used in the early detection of the cervical carcinoma versus the histopathology diagnosis. a selected sample of 107 women attended in the Opportune Detection of Cervicouterine Cancer Program in the Hospital de Zona 46, Instituto Mexicano del Seguro Social in Durango, during the 2003 was included. The application of Papa-nicolaou, acetic acid test, and molecular detection of human papillomavirus, and histopatholgy diagnosis were performed in all the patients at the time of the gynecological exam. The detection and tipification of the human papillomavirus was performed by polymerase chain reaction (PCR) and analysis of polymorphisms of length of restriction fragments (RFLP). Histopathology diagnosis was considered the gold standard. The evaluation of the validity was carried out by the Bayesian method for diagnosis test. the positive cases for acetic acid test, Papanicolaou, and PCR were 47, 22, and 19. The accuracy values were 0.70, 0.80 and 0.99, respectively. since the molecular method showed a greater validity in the early detection of the cervical carcinoma we considered of vital importance its implementation in suitable programs of Opportune Detection of Cervicouterino Cancer Program in Mexico. However, in order to validate this conclusion, cross-sectional studies in different region of country must be carried out.

Given the importance of papanicolaou (Pap) test in the early detection and timely treatment of cervical cancer, present study was designed to determine predictors of a sample of Iranian women's intention to first Pap test practice based on the protection motivation theory (PMT) variables. In this cross-sectional study, a total of 240 women referral to the 30 primary health care clinics were selected. They completed a developed scale based on PMT variables including intention, perceived vulnerability and severity, fear, response costs, response efficacy and self-efficacy. Path analysis was used to determine the association between predictive factors and intention. The results showed that PMT had goodness of fit with a χ2/df = 2.37, df = 28, P= 0.001 and RMSEA = 0.076. PMT explained 42% of the variance in women's intention to get first Pap smear test. Self-efficacy (b = 0.55, Ptheory-based educational interventions associated with Pap testing among women.

The objective of this study was to analyze the diagnostic performance of a newly established immunocytochemical dual-stain protocol, which simultaneously detects p16(INK4a) and Ki-67 expression in cervical cytology samples, for identifying high-grade cervical intraepithelial neoplasia (CIN2+) in women with Papanicolaou (Pap) cytology results categorized as atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesions (LSIL). Residual liquid-based cytology material from 776 retrospectively collected ASCUS/LSIL cases that were available from a recent study evaluating p16 cytology and HPV testing were subjected to p16/Ki-67 dual staining. The presence of 1 or more double-immunoreactive cell(s) was regarded as a positive test outcome, irrespective of morphology. Test results were correlated to histology follow-up. Sensitivity of p16/Ki-67 dual-stain cytology for biopsy-confirmed CIN2+ was 92.2% (ASCUS) and 94.2% (LSIL), while specificity rates were 80.6% (ASCUS) and 68.0% (LSIL), respectively. Similar sensitivity/specificity profiles were found for both age groups of women aged aged ≥30 years. Dual-stain cytology showed comparable sensitivity, but significantly higher specificity, when compared with human papillomavirus (HPV) testing. The results of this study show that p16/Ki-67 dual-stain cytology provided a high sensitivity for the detection of underlying CIN2+ in women with ASCUS or LSIL Pap cytology results, comparable to the rates previously reported for HPV testing and p16 single-stain cytology. However, the specificity of this morphology-independent interpretation of p16/Ki-67 dual-stain cytology testing was further improved compared with the earlier p16 single-stain cytology approach, which required morphology interpretation, and it is significantly higher when compared with HPV testing.

Currently, a comprehensive program for screening and early detection of cervical cancer does not exist in Iran. This study aimed to determine the prevalence of abnormal Papanicolaou (Pap) smears and some related factors among women living in Zanjan, Iran. This cross-sectional study was conducted in 2012 in Zanjan on 4274 married women aged 20-65 years. The study participants were selected through two-stage cluster sampling. After obtaining written consent, demographic and fertility questionnaires were completed. Samples from cervix were obtained through a standard method using the Rover Cervex- Brush. Evaluation and interpretation of the samples were reported using the Bethesda 2001 method. Data were statistically analyzed using chi-square and logistic regression models. Most inflammatory changes in the samples were mild (37.4%). Abnormal atypical changes in the epithelial cells were found in 4.04%. The highest percentage of abnormal changes in the epithelial cells was atypical squamous cells of undetermined significance (ASCUS) (1.9%). Abnormal results of Pap smear was significantly and independently associated with age, papillomavirus infection, and lack of awareness about Pap smear tests. Given the high prevalence of inflammatory and precancerous changes in this study, compared to other studies in Iran and other Muslim countries, and the effect of demographic variables and individual factors on abnormal results, increasing the awareness of women and their families regarding the risk factors for cervical cancer, preventive measures such as screening, and timely treatment seem necessary.

South Asian (SA) immigrants (from Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka) constitute the fastest growing of all Asian American immigrants to the United States, with a growth rate of 106% from 1990 to 2001. Data are lacking on health behaviors of this population subgroup, including cancer-related information. : The purpose of this study was to assess rates and correlates of breast and cervical cancer screening in a community sample of SAs. Participants were recruited from among attendees of 3 community-based agency programs. Data were collected in English, Hindi, and Gujarati from a convenience sample of 198 participants. Two-thirds of the sample (n = 127, 65.5%) had ever had a mammogram, whereas only a third (n = 65, 32.8%) had ever had a Papanicolaou smear or vaginal examination. Several predisposing factors (eg, country of birth, years in the United States, acculturation, age, and acknowledged barriers to screening) were significant predictors of breast and cervical screening, whereas the only enabling factor was past screening behavior. Additional study is warranted on cultural aspects of cancer screening behaviors. These data are formative on facilitators and barriers to mammogram and Papanicolaou test completion among these understudied minority women. Nurses who practice in primary care may begin to target health education based on sociodemographics of SA women and emphasize discussion of barriers to screening.

This study aimed to investigate the value of diffusion-weighted imaging (DWI) in combination with conventional magnetic resonance imaging (MRI) for improving tumor detection in young patients treated with fertility-sparing surgery because of early cervical carcinoma. Fifty-four patients with stage Ia or Ib1 cervical carcinoma were enrolled into this study. Magnetic resonance examinations were performed for these patients using conventional MRI (including T1-weighted imaging, T2-weighted imaging, and dynamic contrast-enhanced MRI) and DWI. The apparent diffusion coefficient (ADC) values of cervical carcinoma were analyzed quantitatively and compared with that of adjacent epithelium. Sensitivity, positive predictive value, and accuracy of 2 sets of MRI sequences were calculated on the basis of histologic results, and the diagnostic ability of conventional MRI/DWI combinations was compared with that of conventional MRI. The mean ADC value from cervical carcinoma (mean, 786 × 10 mm/s ± 100) was significantly lower than that from adjacent epithelium (mean, 1352 × 10 mm/s ± 147) (P = 0.01). When the threshold ADC value set as 1010 × 10 mm/s, the sensitivity and specificity for differentiating cervical carcinoma from nontumor epithelium were 78.2% and 67.2%, respectively. The sensitivity and accuracy of conventional MRI for tumor detection were 76.0% and 70.4%, whereas the sensitivity and accuracy of conventional MRI/DWI combinations were 91.7% and 90.7%, respectively. Conventional MRI/DWI combinations revealed a positive predictive value of 97.8% and only 4 false-negative findings. The addition of DWI to conventional MRI considerably improves the sensitivity and accuracy of tumor detection in young patients treated with fertility-sparing surgery, which supports the inclusion quantitative analysis of ADC value in routine MRI protocol before fertility-sparing surgery.

The aim of this study was to investigate spinal cord structure in patients with cervical spondylosis where conventional MRI fails to reveal spinal cord damage. We performed a cross-sectional study of patients with cervical spondylosis without conventional MRI findings of spinal cord damage and healthy controls. Subjects were studied using spinal diffusion tensor imaging (DTI), precision grip and foot force-tracking tasks, and a clinical examination including assessment of neurological signs. A regional analysis of lateral and medial spinal white matter across multiple cervical levels (C1-C5) was performed. DTI revealed reduced fractional anisotropy (FA) and increased radial diffusivity (RD) in the lateral spinal cord at the level of greatest compression (lowest Pavlov ratio) in patients (p < 0.05). Patients with spondylosis had greater error and longer release duration in both grip and foot force-tracking. Similar spinal cord deficits were present in patients without neurological signs. Increased error in grip and foot tracking (low accuracy) correlated with increased RD in the lateral spinal cord at the level of greatest compression (p ≤ 0.01). Spinal DTI can detect subtle spinal cord damage of functional relevance in cervical spondylosis, even in patients without signs on conventional T2-imaging and without neurological signs. (orig.)

Cervical Papanicolaou smears and paraffin sections of biopsy specimens obtained from women attending dysplasia clinics were examined for viral DNA sequences by in situ hybridization technique using 35 S-labeled cloned recombinant DNA probes of human papillomavirus (HPV) types 6, 11, and 16. These and one unrelated DNA probe complementary to measles virus RNA were labeled by nick translation using either one or two 35 S-labeled nucleotides. Paraffin sections and cervical smears were collected on pretreated slides, hybridized with the probes under stringent or nonstringent conditions for 50 h, and autoradiographed. Additional cervical specimens from the same women were examined for the presence of genus-specific papillomavirus capsid antigen by the immunoperoxidase technique. Preliminary results may be summarized as follows. The infecting virus could be identified in smears as well as in sections. Viral DNA sequences were detected only when there were condylomatous cells in the specimen and in only a proportion of the condylomatous cells. Even under stringent conditions, some specimens reacted with both HPV-6 and HPV-11. In some instances, the cells did not hybridize with any of the three probes even when duplicate specimens contained frankly condylomatous, capsid antigen-positive cells. In situ hybridization of Papanicolaou smears or of tissue sections is a practical method for diagnosis and follow-up of specific papillomavirus infection using routinely collected material

Cervical cancer incidence rates have decreased dramatically since the implementation of the Papanicolaou (Pap) smear. Nevertheless, the American Cancer Society (ACS) estimates for 2013 predicted more than 12,000 new cases of cervical cancer in the United States. Given that some subpopulations in the United States are at a higher risk for cervical cancer than others, efforts to increase screening adherence are warranted. Many studies have explored the demographics of underscreened women, but no systematic reviews of screening demographics in adult US women were identified in the past 10 years, after release of the 2002 ACS cervical cancer screening guidelines. Knowledge of adherence to these guidelines becomes important as new guidelines were developed and released in 2012. The purpose of this systematic review of relevant studies was to identify factors that predict the use of cervical cancer screening in US women. Variables found to be significantly associated with adherence to screening included education, financial status, acculturation, psychosocial issues, and marital status. Using this information, nurse practitioners and other providers can target specific at-risk populations to increase screening by educating women about the need for cervical cancer screening and ensuring access to methods for prevention and early detection of the disease.

Cervical smear is the most economic and efficient diagnostic tool for the screening of cervical cancer. However, since plastic bags have been used in Guanajuato to transport and store smears, we have observed cytological abnormalities which difficult the diagnosis and lead to false negatives. To describe those abnormalities. Out of 340 women registered in a primary care center in Mexico, 68 were selected through systematic random sampling during 2007. A cervical smear was obtained and placed on two slides. The first sample was allowed to dry but the second one was placed into the plastic bag immediately after fixation. After 15 days all the smears were stained with the Papanicolaou technique. A certified pathologist, blinded about the variable of study, interpreted the samples according to the Bethesda system, and evaluated the presence of necrosis, edema, holes, and opportunistic microorganisms. Of the 68 smears exposed to a humid storage, 36 (53%) were inadequate for diagnosis (Fisher's exact probability plastic bags.

Factors associated with colposcopy-histopathology confirmed cervical intraepithelial neoplasia among HIV-infected women from Rio De Janeiro, Brazil.

Full Text Available INTRODUCTION: Despite the availability of preventive strategies (screening tests and vaccines, cervical cancer continues to impose a significant health burden in low- and medium-resourced countries. HIV-infected women are at increased risk for infection with human papillomavirus (HPV and thus development of cervical squamous intraepithelial neoplasia (CIN. METHODS: Study participants included HIV-infected women enrolling the prospective open cohort of Evandro Chagas Clinical Research Institute, Oswaldo Cruz Foundation (IPEC/FIOCRUZ. At cohort entry, women were subjected to conventional Papanicolaou test, HPV-DNA test and colposcopy; lesions suspicious for CIN were biopsied. Histopathology report was based on directed biopsy or on specimens obtained by excision of the transformation zone or cervical conization. Poisson regression modeling was used to assess factors associated with CIN2+ diagnosis. RESULTS: The median age of the 366 HIV-infected women included in the study was 34 years (interquartile range: 28-41 years. The prevalence of CIN1, CIN2 and CIN3 were 20.0%, 3.5%, and 2.2%, respectively. One woman was found to have cervical cancer. The prevalence of CIN2+ was 6.0%. Factors associated with CIN2+ diagnosis in the multivariate model were age < years compared to ≥ 35 years (aPR  =  3.22 95%CI 1.23-8.39, current tobacco use (aPR  =  3.69 95%CI 1.54-8.78, nadir CD4 T-cell count <350 cells/mm3 when compared to ≥ 350 cells/mm3 (aPR  =  6.03 95%CI 1.50-24.3 and concomitant diagnosis of vulvar and/or vaginal intraepithelial lesion (aPR  =  2.68 95%CI 0.99-7.24. DISCUSSION: Increased survival through wide-spread use of highly active antiretroviral therapy might allow for the development of cervical cancer. In Brazil, limited cytology screening and gynecological care adds further complexity to the HIV-HPV co-infection problem. Integrated HIV care and cervical cancer prevention programs are needed for the prevention of cervical

In this study, we identified the factors influencing behavioral intention to undergo Papanicolaou testing among Japanese and Korean women in early adulthood. Their behavioral intentions were compared in this cross-sectional descriptive study. In total, 887 women (Japanese = 498, Korean = 389) aged 20-39 years participated in this study. Using a self-report questionnaire, knowledge, attitudes, subjective norm, perceived behavioral control, and behavioral intention were surveyed. There were significant differences between Japanese and Korean women's scores on all main variables. For Japanese women, all the variables moderately correlated with behavioral intention. In comparison, for Korean women, all independent variables, except for knowledge, moderately correlated with behavioral intention. Through a multiple regression analysis, age, undergoing Papanicolaou testing, attitudes, subjective norm, and perceived behavioral control were identified as significant predictors of behavioral intention among Japanese women. Among Korean women, job status, undergoing a Papanicolaou test, attitudes, subjective norm, and perceived behavioral control were demonstrated as significant predictors of behavioral intention. Health professionals should consider these factors to encourage Papanicolaou testing in women in early adulthood. © 2017 John Wiley & Sons Australia, Ltd.

Background Data from Egyptian studies provide widely varying estimates on the prevalence of pre-malignant and malignant cervical abnormalities and human papilloma virus (HPVs) infection. To define the prevalence and risk factors of pre-invasive and invasive cervical cancer (cacx), a community based full-scale cross sectional, household survey including 5453 women aged between 35 and 60 years was conducted. Methods The study period was between February 2000 and December 2002. Initially, conventional Papanicolaou (Pap) smears were evaluated using the Bethesda system (TBS), followed by colposcopic guided biopsy (CGB) for all epithelial abnormalities (EA). In a third step, HPV was tested on all EA by in-situ hybridization (ISH) using first the broad spectrum HPV probe recognizing HPVs 6, 11, 16, 18, 30, 31, 35, 45, 51 and 52 followed by subtyping with probes 6/11, 16/18 and 31/33. Lastly, unequivocal cases were immunostained for herpes simplex type-2 (HSV-2), cytomegalovirus (CMV), and human immunodeficiency virus (HIV). Results EA representing 7.8% (424/5453), were categorized into atypical squamous cell of undetermined significance (ASCUS) (34.4%), atypical glandular cell of undetermined significance (AGCUS) (15.3%), combined ASCUS and AGCUS (3.1%), low grade squamous intraepithelial lesions (SIL) (41.0%), high grade SIL (5.2%) and invasive lesions (1%). CGB of EA (n = 281) showed non neoplastic lesions (12.8%), atypical squamous metaplasia (ASM) (19.2%), cervical intraepithelial neoplasia I (CIN) (44.4%), CIN II (4.4%), CINIII (2.8%), endocervical lesions (5.2%), combined squamous and endocervical lesions (10.0%), invasive squamous cell carcinoma (SCC) (0.02%) and extranodal marginal zone B cell lymphoma (MZBCL) (0.02%). The overall predictive value of cytology was 87% while the predictive value for high grade lesions was 80%. On histological basis, HPVs were present in 94.3% of squamous lesions while it was difficult to be identified in endocervical ones. ISH

African American youth are among those at greatest risk for experiencing violence victimization. Notably, the mortality rate of cervical cancer for African American women is also twice that of white women. To date, we know of no literature using longitudinal data to examine how violence victimization relates to Papanicolaou (Pap) smear results or cervical cancer in this population. Our study examines how violence victimization during adolescence (age 15 to 18) influences psychological distress, perceived social support, heavy substance abuse, and sexual risk behaviors during emerging adulthood (age 20 to 23), and subsequent Pap smear outcomes during young adulthood (age 29 to 32). This study is based on 12 waves of data collected in a longitudinal study of 360 African American women from mid-adolescence (ninth grade, mean age = 14.8 years) to young adulthood (mean age = 32.0 years). We used structural equation modeling analysis to examine the hypothesized model. Violence victimization during adolescence had a direct effect on decreased social support, increased psychological distress, and increased heavy cigarette use during emerging adulthood. Better social support was also associated with fewer sexual partners during emerging adulthood and lower odds of abnormal Pap smear results during young adulthood. The effect of violence victimization on abnormal Pap smear was mediated by social support. Our results show that violence victimization during adolescence has long-term negative effects through multiple pathways that persist into adulthood. Our findings also suggest that social support may help to compensate against other risk factors. Interventions designed to address the perceived support may help victims cope with their experience.

Attitudes toward cervical cancer and participation in early detection and screening services are well known to be profoundly affected by cultural beliefs and norms. This study explored the attitudes and sociocultural beliefs on cervical cancer screening among Malaysian women. In this qualitative study, in-depth interviews were conducted with 20 Malaysian women, ages 21 to 56 years, who have never had a Papanicolaou (Pap) smear. Respondents generally showed a lack of knowledge about cervical cancer screening using Pap smear, and the need for early detection for cervical cancer. Many believed the Pap smear was a diagnostic test for cervical cancer, and since they had no symptoms, they did not go for Pap screening. Other main reasons for not doing the screening included lack of awareness of Pap smear indications and benefits, perceived low susceptibility to cervical cancer, and embarrassment. Other reasons for not being screened were related to fear of pain, misconceptions about cervical cancer, fatalistic attitude, and undervaluation of own health needs versus those of the family. Women need to be educated about the benefits of cervical cancer screening. Health education, counseling, outreach programs, and community-based interventions are needed to improve the uptake of Pap smear in Malaysia.

Objective To assess the knowledge, attitudes and practices of medical students for health promotion, primary prevention and early detection of breast neoplasm and uterine cervical neoplasm, as well as to make recommendations for improving the Public Health curriculum at the Universidad de los Andes. Methodology This study utilized a survey of medical knowledge, attitudes and practices applied to fifth year Colombian medical students attending the Universidad de los Andes in the first semester of 2013. Results 64/76 students answered the surveys (response rate 84.2 % ): 62.5 % (40/64) and 37.5 % (24/64) response rates from students in their ninth and tenth semesters, respectively; and 64.1 % (41/64) and 35.9 % (23/64) response rates from female and male students, respectively. Knowledge: clinical breast exam (CBE), breast self-examination (BSE) and mammography were recommended by 95.3 % (61/64) of students, 96.9 % (62/64) of medical students and 90.7 % (58/64) of students, respectively. Attitude: the most effective tests to reduce mortality in women aged ≥ 50 years were the Papanicolaou test according to 90.6 % (58/64) of students and mammography according to 82.8 % (53/64) of students. Practice: 55.0 % (35/64) of students had received training in the guidelines and protocols for breast neoplasm and uterine cervical neoplasm screening. Discussion To promote early detection of cervical and breast cancer, knowledge, attitudes and practices must be improved to enhance clinical practices (e.g. Papanicolaou test) and medical student training guidelines or protocols for these two cancers. Overall, with induced demand and support from research communities and institutions seeking to make these improvements, we collaborate to decrease missed opportunities in medical research and Public Health.

The newly gained knowledge of the viral etiology in cervical carcinogenesis has prompted industrial interests in developing virology-based tools for cervical cancer prevention. Due to the long incubation period from viral infection to developing an invasive cancer, a process whose outcome is influenced by numerous life-style and genetic factors, the true efficacy of the genotype-specific human papillomavirus (HPV) vaccines in cervical cancer prevention cannot be determined for another 30 years. Most HPV DNA test kits designed to replace the traditional Papanicolaou (Pap) smears for precancer detection lack the analytical sensitivity and specificity to comprehensively detect all potentially carcinogenic HPVs and to perform reliable genotyping. The authors implemented the classic nested PCR and Sanger DNA-sequencing technology for routine HPV testing. The results showed a true negative HPV PCR invariably indicates the absence of precancerous cells in the cytology samples. However, 80.5% of single positive HPV-16 tests and 97.3% of single positive HPV-18 tests were associated with a negative or a largely self-reversible Pap cytology. Routine sensitive and reliable HPV type-specific or perhaps even variant-specific methods are needed to address the issues of persistence of HPV infection if a virology-based primary cervical screen is used to replace the Pap cytology screening paradigm

Has the ThinPrep method of cervical screening maintained its improvement over conventional smears in terms of specimen adequacy?

LENUS (Irish Health Repository)

Treacy, A

2009-04-01

Liquid-based cytology (LBC) has replaced conventional smear assessment in many centers over recent years. In our laboratory this transfer took place in 1999. At that time we performed a split sample study comparing the conventional method of cervical smear evaluation with the ThinPrep system. This split sample study identified a dramatic improvement in specimen adequacy with LBC. While 11% of conventional preparations were reported as unsatisfactory and almost 9% were reported as suboptimal, evaluation of the same cases using LBC saw this combined figure reduced to 2.3%. AIM: To evaluate whether this dramatic fall in unsatisfactory smears has been maintained with the use of LBC. The database for all smears reported for 2005 (100% LBC) was interrogated. The number of unsatisfactory reports was calculated. The reason for an unsatisfactory report was recorded for each case. The overall unsatisfactory rate was compared with that reported in the 1999 split sample study. A total of 41,312 smear tests were reported in 2005. 1,342 (3.25%) were reported as unsatisfactory. Our findings support the ongoing value of LBC in a routine cervical screening laboratory in terms of continuing to maintain a low rate of unsatisfactory smears.

Cervical cancer incidence in the US-Affiliated Pacific Islands (USAPIs) is double that of the US mainland. American Samoa, Commonwealth of Northern Mariana Islands (CNMI), Guam and the Republic of Palau receive funding from the Centers for Disease Control (CDC) National Breast and Cervical Cancer Early Detection Program (NBCCEDP) to implement cervical cancer screening to low-income, uninsured or under insured women. The USAPI grantees report data on screening and follow-up activities to the CDC. We examined cervical cancer screening and follow-up data from the NBCCEDP programs in the four USAPIs from 2007 to 2015. We summarized screening done by Papanicolaou (Pap) and oncogenic human papillomavirus (HPV) tests, follow-up and diagnostic tests provided, and histology results observed. A total of 22,249 Pap tests were conducted in 14,206 women in the four USAPIs programs from 2007-2015. The overall percentages of abnormal Pap results (low-grade squamous intraepithelial lesions or worse) was 2.4% for first program screens and 1.8% for subsequent program screens. Histology results showed a high proportion of cervical intraepithelial neoplasia grade 2 or worse (57%) among women with precancers and cancers. Roughly one-third (32%) of Pap test results warranting follow-up had no data recorded on diagnostic tests or follow-up done. This is the first report of cervical cancer screening and outcomes of women served in the USAPI through the NBCCEDP with similar results for abnormal Pap tests, but higher proportion of precancers and cancers, when compared to national NBCCEDP data. The USAPI face significant challenges in implementing cervical cancer screening, particularly in providing and recording data on diagnostic tests and follow-up. The screening programs in the USAPI should further examine specific barriers to follow-up of women with abnormal Pap results and possible solutions to address them. Published by Elsevier Ltd.

Background Subjective visual assessment of cervical cytology is flawed, and this can manifest itself by inter- and intra-observer variability resulting ultimately in the degree of discordance in the grading categorisation of samples in screening vs. representative histology. Biospectroscopy methods have been suggested as sensor-based tools that can deliver objective assessments of cytology. However, studies to date have been apparently flawed by a corresponding lack of diagnostic efficiency when samples have previously been classed using cytology screening. This raises the question as to whether categorisation of cervical cytology based on imperfect conventional screening reduces the diagnostic accuracy of biospectroscopy approaches; are these latter methods more accurate and diagnose underlying disease? The purpose of this study was to compare the objective accuracy of infrared (IR) spectroscopy of cervical cytology samples using conventional cytology vs. histology-based categorisation. Methods Within a typical clinical setting, a total of n = 322 liquid-based cytology samples were collected immediately before biopsy. Of these, it was possible to acquire subsequent histology for n = 154. Cytology samples were categorised according to conventional screening methods and subsequently interrogated employing attenuated total reflection Fourier-transform IR (ATR-FTIR) spectroscopy. IR spectra were pre-processed and analysed using linear discriminant analysis. Dunn’s test was applied to identify the differences in spectra. Within the diagnostic categories, histology allowed us to determine the comparative efficiency of conventional screening vs. biospectroscopy to correctly identify either true atypia or underlying disease. Results Conventional cytology-based screening results in poor sensitivity and specificity. IR spectra derived from cervical cytology do not appear to discriminate in a diagnostic fashion when categories were based on conventional screening

To assess the usefulness of magnetic resonance angiography (MRA) in evaluation of stenosis of carotid and large cerebral vessels and cerebral aneurysm. Twenty-seven patients with either arterial stenosis in cervical or intracranial major vessels (n = 18) or cerebral aneurysm (n = 8) or both (n 1) were examined with both MRA and conventional angiography (CA). MRA was performed with 3D TOF technique with magnetization transfer suppression at 1.5T system (Magnetom, Siemens, Germany); both intracranial MRA and cervical MRA in 16 patients, intracranial MRA only in the remaining patients. For evaluation of arterial stenosis, 32 carotid bifurcations and 383 segments of intracranial major vessels were assessed in blind fashion, and were compared with those of CA. Each arterial segment was arbitrarily classified into one of five grades (< 10, 10-49, 50-74, 75-99, 100%) for carotid bifurcation and one of four (< 10, 10-49, 50-99, 100%) for intracranial vessels. For aneurysm, its location, size shape and direction were compared. For arterial stenosis, concordance rate between MRA and CA was 88% (28/32) in carotid bifurcation and 89% (340/383) in intracranial vessels. All discordant cases were overgraded on MRA. For aneurysm, 7 of 9 were demonstrated on both MRA and CA, one of which was partially demonstrated on MRA. One of the other two patients showed aneurysm only on MRA, whereas the remaining one revealed aneurysm only on CA. MRA may be performed as a screening test for occlusive disease of cervical and major intracranial vessels and cerebral aneurysm

Significantly elevated rates of cervical cancer and low rates of Papanicolaou (Pap) smear screening have been documented among HIV-infected women. However, little is known about women’s perceptions of cervical cancer screening utilization. Hence, this study describes barriers and facilitators related to cervical cancer screening in a sample of HIV-infected women seeking care at an integrated HIV clinic in Houston, Texas. Using an inductive qualitative methodological approach, data were obtained from five focus group discussions with a total of 33, HIV-infected women. The majority of the study sample consisted of women who self-identified as Black (69.7%), and reported heterosexual contact as the mode of HIV acquisition (75.8%). Barriers to cervical cancer screening were described as pain and discomfort associated with receiving Pap smears and subsequent procedures; lack of awareness of cervical cancer as a preventable disease; limited transportation access; and systemic issues as it relates to scheduling gynecological appointments. Facilitators were described as awareness of HIV-infected women’s increased risk of cervical cancer and strong provider-patient relationships. To address disparities in cervical cancer screening among low-income HIV-infected women, programs should capitalize on the identified facilitators and alleviate modifiable barriers using multi-level strategies.

Korean adolescent girls are unprepared for cervical cancer prevention due to the lack of a mandatory policy regarding human papilloma virus (HPV) vaccination and school health education regarding cervical cancer. The aim of this study was to determine how aware mothers are about cervical cancer prevention in their adolescent daughters, with a view to developing strategies for expanding primary cervical cancer prevention for adolescent girls through the mothers' involvement. A qualitative design was employed. Nine mothers with adolescent daughters participated in this study and were interviewed using open-ended questions. The themes were extracted by content analysis. A general living area in Seoul, South Korea. The snowball method was used to select mothers. Five themes emerged. In general, the mothers' awareness of cervical cancer was not clear, and they exhibited a lack of awareness of the importance of having a regular Papanicolaou screening test. The mothers recognised that they were role models for their daughters, and realised and accepted the necessity of educating their daughters regarding cervical cancer; however, they perceived barriers related to the prevention of cervical cancer in their daughters. The mothers recommended enforcing sex education in schools and the provision of financial support for HPV vaccination. The mothers' awareness and preparedness with respect to the prevention of cervical cancer in their adolescent daughters were low and inadequate. Mothers should be informed and motivated to play a role in the education of their daughters regarding cervical cancer prevention. Strategies for disseminating information regarding early cervical cancer prevention for adolescent girls are recommended by communicating with both the girls and their mothers and providing them with education regarding cervical cancer prevention.

Atypical squamous cells of undetermined significance (ASCUS) are a cervical cytologic finding category suggestive but not definitive of squamous intraepithelial lesions. ASCUS remains an incompletely described entity and accounts for even 5%-10% of reported Papanicolaou (Pap) smears. The management of women with such cytologic findings remains controversial. The aim of this study was to evaluate the cytology laboratory findings with regards to ASCUS diagnosis, using cervical Pap smears, and colposcopic biopsies, as well as their management. This is a retrospective study of patients with ASCUS Pap smears taken during the period January 2010 - December 2010 in the Second Department of Obstetrics and Gynecology, Aretaieion Hospital. During the study period, 657 Pap smears were examined at the Aretaieion Hospital; moreover, seven patients, whose Pap smears were cytologically diagnosed with ASCUS, were referred from other clinics, providing a total of 42 cases with a descriptive diagnosis of ASCUS for review. Of the 42 cases, eight were not studied because they were either lost in follow-up or they did not have available data. The remaining 34/42 patients were evaluated by colposcopic examination and directed biopsies where necessary. The ratio of ASCUS to low-grade squamous intraepithelial lesion (LGSIL), high-grade squamous cell intraepithelial lesion (HGSIL) or squamous cell carcinoma (SCC) was 5/34, 1/34, and 0/34, respectively. In the 34 ASCUS cases evaluated by colposcopy, the age distribution varied from 22 to 54 years. Eight of 34 cases did not have a child, 7/34 were primigravida, 18/34 were secondi-gravida, and 1/34 had four children. Four out of 34 cases were postmenopausal, 3/34 referred no history of abnormal bleeding, 21/34 were smokers, 6/34 used oral contraceptives, 2/34 used intrauterine devices, 1/34 took replacement of hormones, 4/34 had prior abnormal Pap smears human papillomavirus (HPV), or 1/34 had previous cancer (breast cancer).

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.

Introduction. Cervical cancer is one of the most commonly diagnosed cancers among women in China. The World Health Organization (WHO) recommends routine screening for cervical cancer, and the WHO Global Monitoring Framework suggests that every nation monitors cervical cancer screening. However, little information is available on cervical cancer screening behavior among women in China. Methods. We used data from the 2010 China Chronic Disease and Risk Factor Surveillance System that included 51,989 women aged 18 years and older. We report the proportion of women who reported ever having had a Papanicolaou (Pap) test, stratified by sociodemographic characteristics and geographic region. Multivariable logistic regression modeling was performed to adjust for potential confounders. Results. Overall, 21% of 51,989 women reported having ever had a Pap test. The highest proportion was reported among women aged 30–39 years (30.1%, 95% confidence interval, 26.8%–33.4%). In all geographic regions, women in rural areas were consistently less likely than women in urban areas to report having had a Pap test. Among women who reported ever having a Pap test, 82% reported having the most recent test in the past 3 years. Factors associated with reporting ever having a test were being aged 30–49 years, higher education, being married, and having urban health insurance. Conclusion. Our results indicate that screening programs need to be strengthened along with a more intense focus on specific demographic groups. National cervical cancer screening guidelines and comprehensive implementation strategies are needed to make screening services available and accessible to all women. Implications for Practice: This study is the largest nationwide and population-based assessment of self-reported history of Pap test for cervical cancer screening in China. This article describes cervical cancer screening behavior among women and examines key demographic and geographic factors. Only one

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).

Cervical cancer is the fourth most common malignancy in women worldwide. However, screening with human papillomavirus (HPV) molecular tests holds promise for reducing cervical cancer incidence and mortality in low- and middle-income countries. The performance of the Abbott RealTime High-Risk HPV test (AbRT) was evaluated in 83 cervical smear specimens and compared with a conventional nested PCR coupled to high-throughput sequencing (HTS) to identify the amplicons. The AbRT assay detected at least one HPV genotype in 44.57% of women regardless of the grade of cervical abnormalities. Except for one case, good concordance was observed for the genotypes detected with the AbRT assay in the high-risk HPV category determined with HTS of the amplicon generated by conventional nested PCR. The AbRT test is an easy and reliable molecular tool and was as sensitive as conventional nested PCR in cervical smear specimens for detection HPVs associated with high-grade lesions. Moreover, sequencing amplicons using an HTS approach effectively identified the genotype of the hrHPV identified with the AbRT test.

Full Text Available Summary: Purpose: The purpose of this study was to evaluate the contributions and limitations of the cervical cancer screening test with accuracy in Korea. Methods: This was a retrospective observational study. The study population consisted of all participants who underwent cervical cancer screening test from 2009 to 2014. The data were obtained from National Health Information Database (NHID which represents medical use records of most Koreans. As the indices for contributions and limitations of the screening test, crude detection rate, incidence rate of interval cancer, sensitivity, specificity, and positive predictive value were used. Results: The crude detection rate of screening test per 100,000 participants increased from 100.7 in 2009 to 102.1 in 2014. The incidence rate of interval cancer per 100,000 negatives decreased from 13.0 in 2009 to 10.2 in 2014. The sensitivities of screening test were 88.7% in 2009 and 91.2% in 2014, and the specificities were 98.5% in 2009 and 97.7% in 2014. The positive predictive value of screening decreased from 6.2% in 2009 to 4.3% in 2014. Conclusion: The Korean national cervical cancer screening program has improved in accuracy and has contributed to detection of early stage of cervical cancer over the years. Along with efforts to promote participation in cancer screening programs, quality control over the screening program should be enhanced.

The objective of this study was to compare conventional and conformal techniques of external beam radiotherapy (EBRT) in terms of the dose distribution, tumor response, and side effects in the treatment of locally advanced cervical cancer patients. A retrospective cohort study was conducted on cervical cancer patients who underwent EBRT before brachytherapy in the Radiotherapy Department of Cipto Mangunkusumo Hospital. The prescribed dose distribution, tumor response, and acute side effects of EBRT using conventional and conformal techniques were investigated. In total, 51 patients who underwent EBRT using conventional techniques (25 cases using Cobalt-60 and 26 cases using a linear accelerator (LINAC)) and 29 patients who underwent EBRT using conformal techniques were included in the study. The distribution of the prescribed dose in the target had an impact on the patient’s final response to EBRT. The complete response rate of patients to conformal techniques was significantly greater (58%) than that of patients to conventional techniques (42%). No severe acute local side effects were seen in any of the patients (Radiation Therapy Oncology Group (RTOG) grades 3-4). The distribution of the dose and volume to the gastrointestinal tract affected the proportion of mild acute side effects (RTOG grades 1-2). The urinary bladder was significantly greater using conventional techniques (Cobalt-60/LINAC) than using conformal techniques at 72% and 78% compared to 28% and 22%, respectively. The use of conformal techniques in pelvic radiation therapy is suggested in radiotherapy centers with CT simulators and 3D Radiotherapy Treatment Planning Systems (RTPSs) to decrease some uncertainties in radiotherapy planning. The use of AP/PA pelvic radiation techniques with Cobalt-60 should be limited in body thicknesses equal to or less than 18 cm. When using conformal techniques, delineation should be applied in the small bowel, as it is considered a critical organ according to RTOG

In Mexico, a woman dies of cervical-uterine cancer every 2 hours, indicating a low impact by the national program for early detection of this cancer, principally because of problems related to quality and coverage. Through a qualitative study, we identified the principal barriers to use of the detection program from the point of view of actual and potential program users. Four focus groups were organized in standard conditions in Mexico City (urban, developed) and in the southern state of Oaxaca (rural, economically disadvantaged area). Participants were either women with at least one previous Papanicolaou (Pap) test or women who had never had the test. Barriers to Pap test use included (1) lack of knowledge about cervical-uterine cancer etiology, (2) not knowing that the Pap test exists, (3) the conception that cancer is an inevitably fatal disease, (4) problems in doctor/medical institution-patient relationships, (5) giving priority to unmet needs related to extreme poverty, (6) opposition by the male sexual partner, (7) rejection of the pelvic examination, (8) long waits for sample collection and receiving results, and (9) perceived high costs for care. To increase coverage of the early detection program for cervical-uterine cancer in Mexico, the needs, perceptions, and beliefs of women and their partners must be taken into account when developing policy and planning, given the role these factors play in the decision-making process that leads to their participation or nonparticipation in this program.

Repeated measures of cervical motion in asymptomatic subjects. To introduce a virtual reality (VR)-based assessment of cervical range of motion (ROM); to establish inter and intratester reliability of the VR-based assessment in comparison with conventional assessment in asymptomatic individuals; and to evaluate the effect of a single VR session on cervical ROM. Cervical ROM and clinical issues related to neck pain is frequently studied. A wide variety of methods is available for evaluation of cervical motion. To date, most methods rely on voluntary responses to an assessor's instructions. However, in day-to-day life, head movement is generally an involuntary response to multiple stimuli. Therefore, there is a need for a more functional assessment method, using sensory stimuli to elicit spontaneous neck motion. VR attributes may provide a methodology for achieving this goal. A novel method was developed for cervical motion assessment utilizing an electromagnetic tracking system and a VR game scenario displayed via a head mounted device. Thirty asymptomatic participants were assessed by both conventional and VR-based methods. Inter and intratester repeatability analyses were performed. The effect of a single VR session on ROM was evaluated. Both assessments showed non-biased results between tests and between testers (P > 0.1). Full-cycle repeatability coefficients ranged between 15.0 degrees and 29.2 degrees with smaller values for rotation and for the VR assessment. A single VR session significantly increased ROM, with largest effect found in the rotation direction. Inter and intratester reliability was supported for both the VR-based and the conventional methods. Results suggest better repeatability for the VR method, with rotation being more precise than flexion/extension. A single VR session was found to be effective in increasing cervical motion, possibly due to its motivating effect.

The authors cloned the DNA from a novel human papillomavirus (HPV) present in a cervical condyloma. When DNA from this isolate was hybridized at high stringency with HPV types 1 through 50 (HPV-1 through HPV-50), it showed weak homology with HPV-6 and -16 and stronger homology with HPV-26. A detailed restriction endonuclease map was prepared which showed marked differences from the maps for other HPVs that have been isolated from the female genital tract. Reassociation kinetic analysis revealed that HPV-26 and this new isolate were less than 10% homologous; hence, the new isolate is a noel strain of HPV. The approximate positions of the open reading frames of the new strain were surmised by hybridization with probes derived from individual open reading frames of HPV-16. In an analysis of 175 genital biopsies from patients with abnormal Papanicolaou smears, sequences hybridizing under highly stringent conditions to probes from this novel HPV type were found in 4.2, 6.1, and 2.4% of biopsies containing normal squamous epithelium, condylomata, and intraepithelial neoplasia, respectively. In addition, sequences homologous to probes from this novel isolate were detected in one of five cervical carcinomas examined

The Pap smear unquestionably is a successful screening test for cervical cancer. However, recent advances in technology have raised questions regarding whether the conventional Pap smear is still the standard of care. This article relates issues of screening and cost-effectiveness to the state of the art in thin layer preparations, cytology automation, human papillomavirus screening, human papillomavirus vaccines, and other cervical screening adjuncts. Perhaps nowhere in medicine is clinical decision making being more strongly influenced by market and other external forces than in cervical cytopathology.

We present 2 cases of Cokeromyces recurvatus in routine, liquid-based Papanicolaou tests (ThinPrep). Patient 1 is a healthy, asymptomatic, 26-year-old woman with no pertinent past medical history. Patient 2 is a healthy, asymptomatic, 47-year-old woman with no pertinent past medical history. The Papanicolaou tests from both patients showed many fungal-like elements as globose, yeastlike forms measuring 10 to 30 µm in diameter with multiple, narrowly attached apparent "daughter" buds. This morphology was consistent with Paracoccidioides brasiliensis. However, broad-range fungal polymerase chain reaction and deoxyribonucleic acid sequence analysis performed with GenBank Basic Local Alignment Search Tool showed an exact match for C recurvatus. Our cases highlight the importance of molecular techniques to prevent misdiagnosis of C recurvatus as P brasiliensis, based on morphology alone. There have been 8 previously published cases of C recurvatus infection in humans, 3 of which were reported in the female genital tract.

Pioneers of exfoliative cytology in the 19th century: the predecessors of George Papanicolaou.

The purpose of our study was to summarize the knowledge on exfoliative cytology during the 19th century and to track down Papanicolaou's predecessors. A thorough study of texts, medical books and reports, together with a review of the available literature in PubMed, was undertaken. The study of cytological preparations as a diagnostic procedure can be traced back to the work of the famous French microscopist Alfred François Donné. However, the systematic study and the criteria for the diagnosis of malignant cells should be attributed to Johannes Müller. The increasing interest in the cytological examination of various fluids of the human body can be confirmed by a plethora of studies published during this period. By the end of the 19th century, the invention of new techniques in pathology, such as the introduction of cell block techniques, tissue sections and new staining methods which provided the opportunity to study surgical specimens in three dimensions, led to a decrease in the interest in exfoliative cytology, which was re-discovered by George Papanicolaou almost three decades later. © 2013 John Wiley & Sons Ltd.

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%.

To evaluate the waiting times before obtaining the first colposcopic examination for women with abnormal Papanicolaou smears. Retrospective cohort study conducted on patients who required a colposcopic examination to clarify an abnormal pap test, between 2002 January and 2008 August, in a metropolitan region of Brazil. The waiting times were defined as: Total Waiting Time (interval between the date of the pap test result and the date of the first colposcopic examination); Partial A Waiting Time (interval between the date of the pap test result and the date of referral); Partial B Waiting Time (interval between the date of referral and the date of the first colposcopic examination). Means, medians, relative and absolute frequencies were calculated. The Kruskal-Wallis test and Pearson's chi-square test were used to determine statistical significance. A total of 1,544 women with mean of age of 34 years (SD=12.6 years) were analyzed. Most of them had access to colposcopic examination within 30 days (65.8%) or 60 days (92.8%) from referral. Mean Total Waiting Time, Partial A Waiting Time, and Partial B Waiting Time were 94.5 days (SD=96.8 days), 67.8 days (SD=95.3 days) and 29.2 days (SD=35.1 days), respectively. A large part of the women studied had access to colposcopic examination within 60 days after referral, but Total waiting time was long. Measures to reduce the waiting time for obtaining the first colposcopic examination can help to improve the quality of care in the context of cervical cancer control in the region, and ought to be addressed at the phase between the date of the pap test results and the date of referral to the teaching hospital.

The purpose of this study was to develop and validate a questionnaire to examine women's beliefs about cervical cancer and the Pap test in Chilean women. The questionnaire, developed following the guidelines by Robert de Vellis, is based on the Health Belief Model. The content validity index was 0.93 upon review by 10 Chilean experts. A cross-sectional design was implemented to validate the questionnaire. The sample included 333 women recruited from a women's healthcare center in Santiago, Chile. Exploratory factor analysis was used to evaluate validity and coefficient α to evaluate reliability. After six models were computed, the questionnaire was reduced from 53 to 28 items. The new questionnaire, CPC-28 (in Spanish, Creencias, Papanicolaou, Cancer -28), includes six domains: the barriers domain to take a Pap test, the cues to action domain, the severity domain, the need to have a Pap test domain, the susceptibility to cervical cancer domain, and the benefit domain. The unexpected salient factor "need to have a Pap test" was found as part of the susceptibility domain proposed in the initial questionnaire. This finding is an important topic for future research. The CPC-28 questionnaire explained 49% of the total variance, and the reliability was .735. It was concluded that the CPC-28 questionnaire will have important implications on research, education, and administration across disciplines. Nursing curricula and healthcare providers must stress the importance and reinforce the importance of prevention of cervical cancer and regular Pap test screenings. © 2013 Sigma Theta Tau International.

Full Text Available Background: The role of Papanicolaou (Pap test in cervical cancer screening need not be overemphasized. While most Western countries have adopted the liquid-based cytology (LBC, which is considered superior, many developing countries are still using the conventional Pap smear (CPS technique. Objective: To compare the staining and cytomorphological features on conventional versus liquid-based cervicovaginal smears. Materials and Methods: One hundred and forty cervicovaginal smears prepared by the standard conventional and LBC techniques were interpreted as per the Bethesda system of reporting cervicovaginal smears. Twelve parameters were studied, compared, and statistically analyzed. A P value <0.05 was considered to be statistically significant. Results: 129/140 (92% of CPSs and 130/140 (93% LBC smears were satisfactory. LBC had a significantly shorter screening time (2.0 ± 0.08 vs 4.0 ± 0.65 and better representative material than that of CPS (50% vs 42%. Neutrophils were significantly more in CPS than LBC (96% vs 92% with a P value <0.05 while hemorrhagic background and red blood cells (RBCs were more prominent in CPS. LBC showed significant artifactual changes in squamous epithelial cells. Epithelial abnormalities ranging from atypical squamous cells of undetermined significance (ASCUS to high grade squamous intraepithelial lesion (HSIL were seen in 3% (4 and 2% (2 of CPSs and LBCs, respectively. Organisms were better picked up in CPS (99% in CPS vs 73% LBC with a value of P = 0.0001. Conclusion: Although a shorter screening time and cleaner background are the major advantages of LBC, CPS is not inferior to LBC. Considering the high cost, rather than the advantages associated with LBC, we feel that CPS is a better option for developing countries.

Nuclear magnetic resonance tomography of the cervical canal

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.

Full Text Available OBJECTIVE:To analyze factors associated with cervical cancer screening failure. METHODS:Population-based cross-sectional study with self-weighted two-stage cluster sampling conducted in the cities of Fortaleza (Northeastern Brazil and Rio de Janeiro (Southeastern Brazil in 2002. Subjects were women aged 25-59 years in the last three years prior to the study. Data were analyzed through Poisson regression using a hierarchical model. RESULTS: The proportion of women who did not undergo the Pap smear test in Fortaleza and Rio de Janeiro was 19.1% (95% CI: 16.1;22.1 and 16.5% (95% CI: 14.1;18.9, respectively. Higher prevalence ratios of cervical cancer screening failure in both cities were seen among women with low education and low per capita income, old age, unmarried, who never underwent mammography, clinical breast examination, and blood glucose and cholesterol level testing. Smokers also had lower screening rates compared to non-smoker women and this difference was only statistically significant in Rio de Janeiro. CONCLUSIONS:The study findings point to the need of intervention focusing particularly women in worse socioeconomic conditions and access to healthcare, old-aged and unmarried. Education activities must prioritize screening of asymptomatic women and early diagnosis for symptomatic women and access to adequate diagnostic methods and treatment should be provided.OBJETIVO:Analizar factores asociados a la no realización del examen de Papanicolaou.

Objective: The purpose of the study was to find out the efficacy of Neuromobilization in the treatment of cervical radiculopathy. Methodology: The research is a randomised clinical trial. The duration of the study was 6 months and the research participants were recruited through purpose sampling technique. A sample of 30 patients was taken and assigned to 2 groups randomly i.e. treatment and control group. Conventional treatment consisted of intermittent cervical traction, moist hot pack, isometric neck exercises, was provided to both groups. Participants in the experimental group received neural mobilization as an additional treatment. The measurements were taken in the form of visual analog scale (VAS), and neck disability index (NDI). Results: The result showed the p value (0.00<0.05) of total score of Neck disability index (NDI) means there is a significant difference in both groups. Hence the neural mobilization combined with conventional physical therapy is effective in relieving pain, and reducing disability in subjects with cervical radiculopathy. Conclusions: The study concluded that Neurodynamics together with conventional treatment is an effective treatment approach in treating cervical Radiculopathy. It is recommended that more research work is needed to find out which kind of musculoskeletal problems can have more benefit from this treatment. (author)

Purpose: To assess local control and acute and chronic toxicity with intensity-modulated radiation therapy (IMRT) as adjuvant treatment of cervical cancer. Methods and Materials: Between April 2002 and February 2006, 68 patients at high risk of cervical cancer after hysterectomy were treated with adjuvant pelvic radiotherapy and concurrent chemotherapy. Adjuvant chemotherapy consisted of cisplatin (50 mg/m 2 ) for six cycles every week. Thirty-three patients received adjuvant radiotherapy by IMRT. Before the IMRT series was initiated, 35 other patients underwent conventional four-field radiotherapy (Box-RT). The two groups did not differ significantly in respect of clinicopathologic and treatment factors. Results: IMRT provided compatible local tumor control compared with Box-RT. The actuarial 1-year locoregional control for patients in the IMRT and Box-RT groups was 93% and 94%, respectively. IMRT was well tolerated, with significant reduction in acute gastrointestinal (GI) and genitourinary (GU) toxicities compared with the Box-RT group (GI 36 vs. 80%, p = 0.00012; GU 30 vs. 60%, p = 0.022). Furthermore, the IMRT group had lower rates of chronic GI and GU toxicities than the Box-RT patients (GI 6 vs. 34%, p = 0.002; GU 9 vs. 23%, p = 0.231). Conclusion: Our results suggest that IMRT significantly improved the tolerance to adjuvant chemoradiotherapy with compatible locoregional control compared with conventional Box-RT. However, longer follow-up and more patients are needed to confirm the benefits of IMRT

Caudal cervical spondylomyelopathy is a common neurologic disorder of Doberman pinschers which has a number of striking similarities to cervical spondylotic myelopathy in humans. Diagnosis of this human disease is facilitated considerably by the use of computed tomographic (CT) myelography. Sixteen Doberman pinscher dogs with caudal cervical spondylomyelopathy were studied by conventional myelography followed by CT myelography. A close correlation was noted between the CT myelographic appearance of the cervical spinal cord in these dogs, and that reported for human cervical spondylotic myelopathy. Five dogs had atrophy of the spinal cord, and in another there was an accumulation of contrast medium within the spinal cord. These features are often associated with a poor response to surgical decompression in humans with cervical spondylotic myelopathy. The CT examination provided information that could not be obtained by conventional myelography alone and should be considered as an additional diagnostic procedure in dogs with caudal cervical spondylomyelopathy

Objective: Dose prescription and definition of target volume in brachytherapy of cervical and endometrial cancer are calculated to standard points as Manchester point A or point My(ometrium) in most centers. Calculation of doses to organs at risk mainly relies on ICRU-report 38. But standard dose prescription neglects individual patient anatomy. While MRI and CT had widespread impact on individual planning in external beam radiotherapy, there is still a minor influence on brachytherapy. The impact of individual anatomy on dose distribution in target volume and organs at risk demonstrates the objective of individual brachytherapy planning. Materials and Methods: 8 patients with cervical and 4 patients with endometrial carcinoma underwent MRI of the pelvis with in-situ applicators (ring-tandem applicators for cervical carcinoma and modified Heyman-capsules for endometrial carcinoma). T1w slices were angulated coronal and sagittal to get rectangular reproductions to applicator axis. Orthogonal or isocentric X-ray films for conventional treatment planning were done. MRI-information on target and organs at risk was transformed into coordinates relative to applicator axis and dose calculation on the database of conventional treatment planning was performed by Nucletron Planning System PLATO. Isodoses were projected into MRI slices. Prescribed dose to patients with cervical cancer was 8.5 Gy to point A resp. 10 Gy to point My (2cm below fundal myometrium and 2cm lateral applicator axis) in endometrial cancer. Results: Dose prescription to Manchester point A or point My represented in only 50% of cases uterine serosa. Instead of 2cm lateral of applicator axis, uterine surface ranged from 1.0 cm to 3.9 cm at the level of point A (mean 2.25 cm coronal and 1.77 cm sagittal) and from 1.5 cm to 4.4 cm at the level of point My (mean 2.7 cm coronal and 2.1 cm sagittal). Uterine volume ranged from 69 cc to 277 cc, mean volume was 150cc. Dose-volume histograms of patients with

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.

Marcus Vinicius Von Zuben

Full Text Available CONTEXT AND OBJECTIVE: In the northern region of Brazil, cervical cancer is the most important cause of cancer-related deaths among women. There is considerable likelihood, however, that official incidence and mortality figures are greatly underestimated. The aim of this study was to estimate the repercussions from improvement in cervical cancer screening programs on the incidence of pre-invasive and invasive cervical lesions in a municipality in this region. DESIGN AND SETTING: This was a quasi-experimental study that assessed process dimensions relevant to the program objectives. The study comprised a sample of 2,226 women seen at primary healthcare units in Cruzeiro do Sul, a small city in the Brazilian Amazon region, from April 2003 to July 2004. METHODS: Women were recruited through local radio advertisements and by oral communication from the investigators. The women answered a structured questionnaire and underwent pelvic examination, which included Papanicolaou (Pap smears and naked-eye inspection of the cervix after applying diluted acetic acid. Women with positive Pap smears or abnormal gynecological examination were referred for colposcopy and possible biopsy, diathermic large loop excision of the transformation zone or conization. RESULTS: The results obtained were compared with historical official data retrieved from the Brazilian Ministry of Health’s database. Intervention resulted in a 40% increase in positive Pap smears and detection of cancer was nine times higher than had been observed in routine screening. CONCLUSIONS: Detection of pre-invasive and invasive cervical lesions in the intervention group was remarkably higher than among women seen during routine screening.

Full Text Available The cervical-vaginal cytology can be interpreted after many classifications, starting from Babeú- Papanicolaou and ending with the Bethesda system, but no matter what the interpretation manner is it is really important to have a good quality of the smears and an experienced cytologist. If we refer to the total number of cases from the lot presented - 16732 cases, the results are satisfactory; 83% smears having normal limits, 10.14% MCB, 2.71% L-SIL, 0.82% H-SIL, 2.77% ASCUS, 0.10% AGC. In Iaúi there are significantly more patients with benign cell changes and L- SIL, while in Buzău there are significantly more patients with a normal smear, but there is also a higher frequency of theatypical squamous cells with an undetermined significance. Classically specialists say that 50-75% of the false negative results are due to the errors made when harvesting the sample. In conclusion we estimate that considering the present conditions in our country where the lack of interest and financial possibilities do not allow an action of detecting the lesions of the cervix organized nationwide, we can still make a selection of the cases with a high risk by making a free Pap smear for all the patients that come to a specialized service, either state or private, provided they respect the protocol of harvesting the cervical secretions, of preparing and reading/interpreting the smears.

This study aims to develop a prediction model for spontaneous regression of cervical intraepithelial neoplasia grade 2 (CIN 2) lesions based on simple clinicopathological parameters. The study was conducted at Maastricht University Medical Center, the Netherlands. The prediction model was developed in a retrospective cohort of 129 women with a histologic diagnosis of CIN 2 who were managed by watchful waiting for 6 to 24months. Five potential predictors for spontaneous regression were selected based on the literature and expert opinion and were analyzed in a multivariable logistic regression model, followed by backward stepwise deletion based on the Wald test. The prediction model was internally validated by the bootstrapping method. Discriminative capacity and accuracy were tested by assessing the area under the receiver operating characteristic curve (AUC) and a calibration plot. Disease regression within 24months was seen in 91 (71%) of 129 patients. A prediction model was developed including the following variables: smoking, Papanicolaou test outcome before the CIN 2 diagnosis, concomitant CIN 1 diagnosis in the same biopsy, and more than 1 biopsy containing CIN 2. Not smoking, Papanicolaou class predictive of disease regression. The AUC was 69.2% (95% confidence interval, 58.5%-79.9%), indicating a moderate discriminative ability of the model. The calibration plot indicated good calibration of the predicted probabilities. This prediction model for spontaneous regression of CIN 2 may aid physicians in the personalized management of these lesions. Copyright © 2016 Elsevier Inc. All rights reserved.

The incidence of cervical cancer is expected to rise sharply in China. A reliable routine human papillomavirus (HPV) detection and genotyping test to be supplemented by the limited Papanicolaou cytology facilities is urgently needed to help identify the patients with cervical precancer for preventive interventions. To this end, we evaluated a nested polymerase chain reaction (PCR) protocol for detection of HPV L1 gene DNA in cervicovaginal cells. The PCR amplicons were genotyped by direct DNA sequencing. In parallel, split samples were subjected to a Digene HC2 HPV test which has been widely used for “cervical cancer risk” screen. Of the 1826 specimens, 1655 contained sufficient materials for analysis and 657 were truly negative. PCR/DNA sequencing showed 674 infected by a single high-risk HPV, 188 by a single low-risk HPV, and 136 by multiple HPV genotypes with up to five HPV genotypes in one specimen. In comparison, the HC2 test classified 713 specimens as infected by high-risk HPV, and 942 as negative for HPV infections. The high-risk HC2 test correctly detected 388 (57.6%) of the 674 high-risk HPV isolates in clinical specimens, mislabeled 88 (46.8%) of the 188 low-risk HPV isolates as high-risk genotypes, and classified 180 (27.4%) of the 657 “true-negative” samples as being infected by high-risk HPV. It was found to cross-react with 20 low-risk HPV genotypes. We conclude that nested PCR detection of HPV followed by short target DNA sequencing can be used for screening and genotyping to formulate a paradigm in clinical management of HPV-related disorders in a rapidly developing economy

To determine the functional relevance of diffusion tensor imaging (DTI) metrics and conventional MRI (signal intensity change in T2, compression ratio) by measuring the correlation of these parameters with clinical outcome measured by the modified Japanese Orthopedic Association (mJOA) score. A total of 20 cervical myelopathy (CM) patients participated in this prospective cohort study. The severities of CM were assessed using the mJOA score. Conventional MRIs (T2-weighted images) measuring the signal changes of spinal cords and the degree of compression at the lesion level and DTI metrics [fractional anisotropy (FA), apparent diffusion coefficient (ADC)] at each lesion and below each lesion (C7/T1) level were acquired using a 3-T Achieva MRI. These parameters were correlated with the mJOA scores to determine the functional relevance. Ninety percent of CM patients showed signal changes and 30 % of patients noted a more than 40% canal compression ratio in conventional MRIs at the lesion level; however, these findings were not correlated with the mJOA score (p < 0.05). In contrast, FA values on DTI showed high sensitivity to CM (100%), which was well correlated with the mJOA score (p = 0.034, r = 0.475) below the lesion level (C7/T1). This study showed a meaningful symptomatic correlation between mJOA scores and FA values below the lesion levels in CM patients. It could give us more understanding of the pathological changes in spinal cords matched with various clinical findings in CM patients than the results from conventional MRI. (orig.)

Imaging the cervical spine following rugby related injury

Rugby Union and Rugby League are popular sports with high participation across the world. The high impact nature of the sport results in a high proportion of injuries. Rugby has an association with cervical spine injury which has potentially catastrophic consequences for the patient. Anecdotal evidence suggests that radiographers find it challenging to visualise the cervicothoracic junction on the lateral supine cervical spine projection in broad shouldered athletes. This paper intends to analyse the risk factors for cervical spine injuries in rugby and discuss the imaging strategy in respect to radiography and CT scanning in high risk patient groups such as rugby players who are suspected of suffering a cervical spine injury. - Highlights: • Rugby as a participation sport represents a risk of cervical spine injury. • Conventional radiography lacks sensitivity in identifying cervical spine injury. • The body habitus of rugby players makes the imaging of the cervicothoracic junction challenging. • CT scanning should replace radiography in the event of serious suspicion of cervical spine injury. • The notion of CT being a high dose modality should be questioned.

Purpose: To compare selenium-based digital radiography with conventional screen-film radiography of the cervical spine. Materials and Methods: In a prospective study X-ray images of the cervical spine were obtained in 25 patients using selenium-based digital radiography and conventional screen-film radiography. All images were clinically indicated. Selenium-based digital radiography and conventional screen-film radiography were used in a randomized order. Four radiologists independently evaluated all 50 examinations for the visibility of 76 anatomic details according to a five-level confidence scale (1=not visible, 5=very good visibility). From the evaluation of these anatomic details scores for the upper and middle cervical spine, the cervicothoracic junction and the cervical soft tissues were calculated. The scores for selenium-based digital radiography and conventional screen-film radiography were compared using Wilcoxon's signed rank test. Results: From a total of 15,200 observations (608 per patient) the following scores were calculated for selenium-based digital radiography and for screen-film radiography, respectively: Upper cervical spine 3.88 and 3.94; middle cervical spine 4.60 and 4.48; cervico-thoracic junction 3.64 and 2.62; cervical soft tissue 4.47 and 3.46.

The Papanicolaou test generates pain and embarrassment, and cytology screening has limited sensitivity for detection of cervical neoplasia. These factors urge the use of another screening test that can overcome these limitations. We explore a completely noninvasive method using detection of human papillomavirus (HPV) DNA in women's menstrual blood (MB). The participants were divided into 3 cohorts: (i) 235 patients with cervical intraepithelial neoplasia 3 (CIN 3) (n = 48), CIN 2 (n = 60), CIN 1 (n = 58), or condyloma acuminatum (CAC) (n = 69) before treatment or remission; (ii) from the first cohort of patients, 108 CIN 3 or CIN 2 patients after treatment and 62 CIN 1 or CAC patients after remission; and (iii) 323 apparently normal subjects (ANS) without any cervical disease. The HPV genotypes of the infected patients were confirmed by direct sequencing. Quantitative real-time PCR (QRT-PCR) was used to measure the MB HPV16 load for 15 infected patients. Results showed that the sensitivity, specificity, and positive and negative predictive values for detection of MB HPV DNA in samples from patients with CIN or CAC were 82.8%, 93.1%, 90.0%, and 87.9%, respectively. Moreover, MB HPV DNA was found in samples from 22.2% of CIN 3 or CIN 2 patients after treatment, 0.0% of CIN 1 or CAC patients after remission, and 8.1% of ANS, 4 of whom were found to have CIN 1 or CAC. Furthermore, QRT-PCR showed that the normalized MB HPV16 DNA copy numbers in samples from patients with CIN 1 to CIN 3 were significantly increased. These preliminary results suggested that MB HPV DNA is a potential noninvasive marker for these premalignant cervical diseases.

Their mean age at disease onset was 41.4 + 13.4 years (range of 18-73)and mean duration of disease was 9.1+-6.28 years (range of 2-34). Their demographic data including rheumatoid factor status was obtained. Standard conventional radiographs cervical spine were obtained to study the cervical spine changes. Cervical radiographic changes were found in 34 patients (27 females and 7 males) 10 had subluxation (7 with atlanto-axial subluxation,2 with sub-axial subluxation,and one with lateral subluxation ). No vertical impaction was seen. Erosion of odontoid process was seen in one patient .All were rheumatoid seropositive Cervical spine changes in patients with rheumatoid arthritis are common, in particular subluxation in the upper cervical spine. Our study showed somewhat lesser prevalence of these changes. These were clinically correlated with disease duration, female sex, and rheumatoid factor, but were not clinically significant. (author)

Moreover, MB HPV DNA was found in samples from 22.2% of CIN 3 or CIN 2 patients after treatment, 0.0% of CIN 1 or CAC patients after remission, and 8.1% of ANS, 4 of whom were found to have CIN 1 or CAC. Furthermore, QRT-PCR showed that the normalized MB HPV16 DNA copy numbers in samples from patients with CIN 1 to CIN 3 were significantly increased. These preliminary results suggested that MB HPV DNA is a potential noninvasive marker for these premalignant cervical diseases. PMID:20089764

To assess the diagnostic efficacy of magnetic resonance (MR) imaging in the detection of a vertebral artery injury occurring from major cervical spine trauma. Conventional MR findings of 63 patients and 63 control subjects were compared to detect a possible change in the vertebral arteries resulted from trauma. Plain films, CT and clinical records were also reviewed to correlate the degree of cervical spine injury with vascular change. Nine cases of absent flow signals in vessel lumen were observed in eight patients and one was observed in the control group. Patients more frequently demonstrated other abnormalities such as intraluminal linear signals (n=3) or focal luminal narrowing (n=9) but there was no statistical significance. There was a close relationship between degree of cord damage and occlusion of the vertebral artery. Conventional MR imaging is useful in the detection of vertebral artery occlusion resulting from cervical spine trauma.

The so-called 'myelopathy hand', or characteristic finger paralysis, often recognized in cervical compression myelopathy, has been considered a unique manifestation of cervical myelopathy. We used our original grip and release test, a 15-second test in which finger motion is captured with a digital camera, to investigate whether cervical radiculopathy has the same characteristics as myelopathy hand. Thirty patients with pure radiculopathy, id est (i.e.), who had radiating arm pain and evidence of corresponding nerve root impingement on X-ray images or MRI scans, but did not have spinal cord compression, served as the subjects. In contrast to other radiculopathies, C7 radiculopathy was manifested by a significant reduction in the number of finger motion cycles on the affected side in comparison with the unaffected side, the same as in myelopathy hand. Uncoordinated finger motion was significantly more frequent on the affected side in C6 radiculopathy than on the unaffected side. These findings contradict the conventional notion that myelopathy hand is a unique manifestation of cervical myelopathy, but some radiculopathies manifested the same kinds of finger paralysis observed in myelopathy hand.

Cervical cancer is a leading cause of death in underserved areas of Brazil. This prospective randomized trial involved 200 women in southern/central Brazil with abnormal Papanicolaou tests. Participants were randomized by geographic cluster and referred for diagnostic evaluation either at a mobile van upon its scheduled visit to their local community, or at a central hospital. Participants in both arms underwent colposcopy, in vivo microscopy, and cervical biopsies. We compared rates of diagnostic follow-up completion between study arms, and also evaluated the diagnostic performance of in vivo microscopy compared with colposcopy. There was a 23% absolute and 37% relative increase in diagnostic follow-up completion rates for patients referred to the mobile van (102/117, 87%) compared with the central hospital (53/83, 64%; P = 0.0001; risk ratio = 1.37, 95% CI, 1.14-1.63). In 229 cervical sites in 144 patients, colposcopic examination identified sites diagnosed as cervical intraepithelial neoplasia grade 2 or more severe (CIN2+; 85 sites) with a sensitivity of 94% (95% CI, 87%-98%) and specificity of 50% (95% CI, 42%-58%). In vivo microscopy with real-time automated image analysis identified CIN2+ with a sensitivity of 92% (95% CI, 84%-97%) and specificity of 48% (95% CI, 40%-56%). Women referred to the mobile van were more likely to complete their diagnostic follow-up compared with those referred to a central hospital, without compromise in clinical care. In vivo microscopy in a mobile van provides automated diagnostic imaging with sensitivity and specificity similar to colposcopy.

Acute injuries of the cervical spine are the most common causes of severe disability following trauma, yet the diagnosis of these injuries are often delayed and the treatment, inadequate. Traumatic injuries of the cervical spine are diagnosed by radiological examinations. And complete evaluations of bony structures and soft tissue changes on conventional radiograms are very important for determining the therapeutic plans and prognoses of the injuries patients. During the period of 5 years from June 1976 to May 1981, the radiological and clinical evaluation had been made on 38 patients suffered from acute cervical spinal injuries which were confirmed by the radiological examinations. The results were as follows. 1. Age distribution of total 38 patients was broad ranging from 19 years to 72 years. 2. The most common cause of injury was traffic accident, next fall down, other accident respectively. 3. Levels of the cervical spinal injuries were as follows: Upper cervical spine in 15.8%, lower cervical spine in 84.2%, and the most common injuries level was C 5. Most of the lower cervical spinal injuries were located in the vertebral body and spinous process. 4. Anatomical sites of the cervical spinal injuries were as follows; vertebral body in 55.5%, spinous process in 23.7%, neural arch in 15.8%, and locked facet in 18.4%, etc. 5. Most of the patients with severe mental changes were injuries in upper cervical spine rather than lower. And most of the patients with quadriplegia or paraplegia were shown marked disruption of spinal canal.

Full Text Available This objective of our study was to determine the prevalence of a Trichomonas vaginalis diagnosis in routine Papanicolaou smears and whether it is seasonal. We reviewed the diagnosis rendered for 93,681 Papanicolaou smears evaluated at a medical school hospital laboratory between 1992 and 1997. The occurrence of a diagnosis of T. vaginalis was analyzed by year, by quarter, and by month using a generalized linear regression model. The prevalence of a T. vaginalis diagnosis during the 6-year study period was 3.1%. The between-month and between-quarter comparisons of prevalence were not statistically different. In the population reported here, the prevalence of a Papanicolaou smear diagnosis of T. vaginalis was low and no seasonal difference in making this diagnosis was identified.

Computerized tomographic study of human cadavers undergoing traction and flexion-extension bending. To investigate the feasibility of using computerized tomography techniques to quantify relative vertebral motions of the cervical spine and cervicothoracic junction (CTJ), and to define normative CTJ kinematics. Despite developing an understanding of the mechanical behavior of the cervical spine, little remains known about the cervicothoracic junction. The CTJ is more difficult to image than other cervical regions given the anatomic features of the surrounding bones obstructing CTJ visualization. As such, limited data have been reported describing the responses of the CTJ for motions and loading in the sagittal plane, confounding the clinical assessment of its injuries and surgical treatments used at this region. Helical CT images of the cervical spine and CTJ were acquired incrementally during each of flexion, extension, and cervical traction. Vertebral surfaces were reconstructed using the specialized image analysis software, 3DVIEWNIX. A mathematical description of relative vertebral motions was derived by computing rigid transformations. Euler angles and translations were calculated. Regional spine stiffness was defined for traction. The CTJ was found to be much stiffer (779 N/mm) than the cervical spine (317 N/mm) in tension. In flexion-extension bending, the CTJ was similar to the lower cervical spine. The CTJ demonstrated significantly less coupled motion than the cervical spine. The CTJ, as a transition region between the cervical and thoracic spines, has unique kinematic characteristics. This application of kinematic CT methods is useful for quantifying unreported normative ranges of motion for the CTJ, difficult by other conventional radiologic means.

The purpose of this study was to investigate the clinical feasibility of FDG-PET(Positron Emission Tomography) scan in patients with clinically no evidence of disease after treatment of cervical cancer. One hundred and one patients with clinically NED(no evidence of disease) state after treatment of cervical cancer underwent PET scan. FDG-PET scan was obtained with a GE Advance Scanner, beginning at 50 minutes after injection of 370-555 MBq(10-15 mCi) of 18F FDG. Regional scan was also obtained with emission image. Uptake exceeding 3.0 SUV was determined as a positive finding. Recurrence was confirmed by CT, MRI, and needle biopsy if possible. Among 101 patients showing no evidence of disease, 17 patients(16.8%) showed abnormal PET scan findings. Clinically, 8 patients(7.9%) were confirmed to have recurrent lesion by CT, MRI or by needle biopsy. PET scan could detect recurrent lesions in the mediastinum or lung(10/17), pelvis(7/17), and supraclavicular lymph node(2/17). The sensitivity and specificity of PET scan in patients with cervical cancer showing no evidence of disease were 100% and 90.3%, respectively. The positive predictive value, negative predictive value and false positive rate were 47.1%, 100% and 52.9%. PET scan could detect 7.9% of early recurrence in patients with cervical cancer with NED status. FDG-PET scan may be a useful method in detecting metastases or recurrence of a cervical cancer showing no evidence of disease by routine conventional imaging studies

Método : estudio transversal en el cual se utilizó la escala de conocimientos, actitudes y prácticas, en junio y octubre de 2013, con 240 mujeres de entre 24 y 59 años. Resultados : se observaron deficiencias en el conocimiento, porque a pesar de tener información sobre el examen, este era practicado sólo para la detección de enfermedades de transmisión sexual. En el ítem práctica, se percibió que las mujeres solteras de hasta 29 años presentaban mayores chances de práctica inadecuada cuando comparadas con aquellas mayores/casadas, lo que aumenta la probabilidad de desarrollar cáncer de cuello uterino. La mayor dificultad para el examen se debió a la falta de materiales (68,1%. Conclusión : la explicación a las mujeres sobre el examen requiere de una comunicación efectiva entre los usuarios y los profesionales de la salud, así como la garantía y soporte continuo de la atención por parte de los administradores.

SU-F-T-633: Cyberknife Boost Versus Conventional Tandem and Ovoid Treatment for Cervical Cancer

Energy Technology Data Exchange (ETDEWEB)

Santoro, J; Witten, M; Haas, J [Winthrop University Hospital, Lynbrook, NY (United States)

Purpose: Brachytherapy has been the standard of care for cervical cancer for 100 years. The treatment can be administered using an HDR (high dose rate) remote afterloader with a {sup 192}Ir source in an outpatient setting, a PDR afterloader with a {sup 192}Ir source, or with LDR manually loaded or a remote afterloader utilizing {sup 192}Ir or {sup 137}Cs sources in an inpatient setting. The procedure involves the placement of a tandem and ovoid, tandem and ring, or tandem and cylinder applicator in an operating room setting with the patient under general anesthesia. Inaccuracies introduced into the process occurring between placement of the applicator and actual delivery can introduce uncertainty into the actual dose delivered to the tumor and critical organs. In this study we seek to investigate the dosimetric difference between an SBRT-based radiotherapy boost and conventional Brachytherapy in treating cervical cancer. Methods: Five HDR tandem and ovoid patients were planned using the Brachyvision treatment planning system and treated in four fractions using the Varian Varisource afterloader (Varian Medical Systems). For the same cohort, the patient planning CTs were imported into Multiplan (Accuray Inc) and a dose/fractionation-equivalent CyberKnife SBRT plan was retrospectively generated. Dosimetric quantities such as target/CTV D90, V90, D2cc for rectum, bladder, and bowel were measured and compared between the two modalities. Results: The CTV D90 for the tandem and ovoid was 2540cGy (90.7%) and 3009cGy (107.5%) for the CyberKnife plan. The D2cc for the rectum, bladder, and bowel were 1576cGy, 1641cGy, and 996cGy for the tandem and ovoid and 1374cGy, 1564cGy, and 1547cGy for CyberKnife. Conclusion: The D2cc doses to critical structures are comparable in both modalities. The CTV coverage is far superior for the CyberKnife plan. The dose distribution for CyberKnife has the advantage of increased conformality and lower maximum CTV dose.

Background: High dose irradiation of the posterior cervical lymph nodes usually employs applied electron fields to treat the target volume and maintain the spinal cord dose within tolerance. In the light of recent advances in elective lymph node localisation we investigated optimization of field shape and electron energy to treat this target volume. Methods: In this study, three sequential hypotheses were tested. Firstly, that customization of the electron fields based on the nodal PTV outlined gives better PTV coverage than conventional field delineation. Using the consensus guidelines, customization of the electron field shape was compared to conventional fields based on bony landmarks. Secondly, that selection of electron energy using DVHs for spinal cord and PTV improves the minimum dose to PTV. Electron dose-volume histograms (DVHs) for the PTV, spinal cord and para-vertebral muscles, were generated using the Monte Carlo electron algorithm. These DVHs were used to compare standard vs optimized electron energy calculations. Finally, that combination of field customization and electron energy optimization improves both the minimum and mean doses to PTV compared with current standard practice. Results: Customized electron beam shaping based on the consensus guidelines led to fewer geographical misses than standard field shaping. Customized electron energy calculation led to higher minimum doses to the PTV. Overall, the customization of field shape and energy resulted in an improved mean dose to the PTV (92% vs 83% p = 0.02) and a 27% improvement in the minimum dose delivered to the PTV (45% vs 18% p = 0.0009). Conclusions: Optimization of electron field shape and beam energy based on current consensus guidelines led to significant improvement in PTV coverage and may reduce recurrence rates

Full Text Available Bacground/Aim. Diagnostic protocol for patients with degenerative diseases of the cervical spine demands, in parallel with neuroimaging methods, functional evaluation through neurophysiological methods (somatosensitive and motor evoked potentials and electromyoneurography aiming to evaluate possible subclinical affection of spinal medula resulting in neurological signs of long tract abnormalities. Considering diversities of clinical outcomes for these patients, complex diagnostic evaluation provides a prognosis of the disease progression. Methods. The study included 21 patients (48.24 ± 11.01 years of age with clinical presentation of cervical spondylarthropathy, without neuroradiological signs of myelopathy. For each patient, in addition to conventional neurophysiological tests (somatisensory evoked potentials - SSEP, motor evoked potentials - MEP, electromyoneurography - EMG, nerve conduction studies, we calculated central motor conduction time (CMCTF, as well the same parameter in relation to a different position of the head (maximal anteflexion and retroflexion, so-called dynamic tests. Results. Abnormalities of the peripheral motor neurone by conventional EMNeG was established in 2/3 of the patients, correponding to the findings of root condution time. Prolonged conventional CVMPF were found in 29% of the patients, comparing to 43% CVMPF abnormalities found with the dynamic tests. In addition, the SSEP findings were abnormal in 38% of the patients with degenerative diseases of the cervical spine. Conclusion. An extended neurophysiological protocol of testing corticospinal functions, including dynamic tests of central and periheral motor neurons are relevant for detection of subclinical forms of cervical spondylothic myelopathy, even at early stages. In addition to the conventional neurophysiological tests, we found usefull to include the dynamic motor tests and root conduction time measurement in diagnostic evaluation.

Cervical cancer screening with liquid-based cytology (LBC) has been developed as an alternative to the conventional Papanicolaou (CP) smear. Cost-effectiveness is one of the issues when evaluating LBC. Based on the results of a Dutch randomised controlled trial, we conducted cost-effectiveness threshold analyses to investigate under what circumstances manually screened ThinPrep LBC is cost-effective for screening. The MISCAN-Cervix microsimulation model and data from the Dutch NETHCON trial (including 89,784 women) were used to estimate the costs and (quality-adjusted) life years ((QA)LYs) gained for EU screening schedules, varying cost-effectiveness threshold values. Screening strategies were primary cytological screening with LBC or CP, and triage with human papillomavirus (HPV) testing. Threshold analyses showed that screening with LBC as a primary test can be cost-effective if LBC is less than 3.2 more costly per test than CP, if the sensitivity of LBC is at least 3-5 % points higher than CP, if the quality of life for women in triage follow-up is only 0.39, or if the rate of inadequate CP smears is at least 16.2 %. Regarding test characteristics and costs of LBC and CP, only under certain conditions will a change from CP to manually screened ThinPrep LBC be cost-effective. If none of these conditions are met, implementation of manually screened ThinPrep LBC seems warranted only if there are advantages other than cost-effectiveness. Further research is needed to establish whether other LBC systems will be more favorable with regard to cost-effectiveness.

Full Text Available OBJECTIVE: To determine the coverage and focus of cervical cancer screening (Pap smears in a population-based sample in Brazil. METHODS: Cross-sectional cluster survey covering 1 730 women aged 20 years or older with a history of sexual activity. Information was collected on social, demographic and behavioral variables, knowledge of and use of the Pap test. RESULTS: Of women aged 25-59 years, who are the target population of the national cervical cancer screening program, 78.7% had had at least one Pap test in their lifetime, and 68.8% had had a Pap test in the last 3 years. Statistics for focus of the program showed that of the 637 women who reported having a Pap test in the last year, only 20.6% actually required one. The remainder were either outside the age range or had had another test less than 30 months previously. Prevalence of not having been tested in the previous 3 years was highest among black (41.7% and low-income women (64.3%, and among those at greatest risk for cervical cancer (62.3% for women with three or more risk factors. Focus was inversely related to socioeconomic status. CONCLUSION: Coverage rates were similar to those reported in other national studies, but this is the first report to examine the focus of the national program. We show that 8 of every 10 Pap tests were not necessary. Coverage levels remain unacceptably low among women of low socioeconomic status and those at greatest risk for cervical cancer.OBJETIVO: Determinar la cobertura y la concentración poblacional del tamizaje del cáncer cervicouterino (con la prueba de Papanicolaou en una muestra poblacional en el Brasil.

Recently, attempts have made to use radiotherapy in combination with chemotherapy in various solid tumors including cervical cancer. Twenty-four patients with locally advanced cervical cancer were treated with concurrent Carboplatin (16-24 mg/m 2 /day) or Nedaplatin (20 mg/m 2 /week) and conventional radiotherapy. Of 13 evaluable patients, there were nine complete responders and four partial responders. There was no renal damage or grade 4 hematological toxicity. Gastrointestinal adverse reactions were mild. One patient had grade 3 dermatologic toxicity after delayed radiation therapy. This pilot study suggests that daily Carboplatin or weekly Nedaplatin administered with standard radiation therapy is safe, well-tolerated, and thus may be useful as a radiation sensitizer in the treatment of locally advanced cervical cancer.

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

The aim of this study was to evaluate osseointegration and crestal bone height in implants with a triangular cervical design in comparison with a standard rounded cervical design. The control group consisted of 24 implants with a standard cervical design, and the test group of 24 implants with a triangular cervical design. The implants were inserted in healed bone in six American Foxhounds. Crestal bone height and tissue thickness in the cervical portion were measured after 12 weeks healing. Data analysis found mean crestal bone loss of: 0.31 ± 0.24 mm on the buccal side, 0.35 ± 0.14 mm on the lingual in the test group, and 0.71 ± 0.28 mm buccal loss, and 0.42 ± 0.30 mm lingual in the control group; with statistically significant differences on the buccal aspect ( p = 0.0019). Mean tissue thickness in the test group was 1.98 ± 0.17 mm on the buccal aspect, and 2.43 ± 0.93 mm in the lingual; in the control group it was 2.48 ± 0.61 mm buccal thickness, and 2.88 ± 0.14 mm lingual, with significant differences on both aspects ( p = 0.0043; p = 0.0029). The results suggest that greater thickness of peri-implant tissue can be expected when the triangular cervical implant design is used rather than the standard cervical design.

Cervical cancer screening in women younger than 30 years relies on cervical cytology because of the poor performance of human papillomavirus (HPV) DNA testing in this age group. To determine the performance of in-cell HPV E6, E7 mRNA quantification (HPV OncoTect) for the detection of high-grade cervical intraepithelial neoplasia in women younger than 30 years. We analyzed 3133 cytology specimens from a screening population of women aged 19-75 years investigate HPV OncoTect as a triage/secondary screening test for atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesion (LSIL) cytology in women younger than 30 years. Test results were compared to histology in 246 cases. The sensitivity of E6, E7 mRNA was 89% for CIN 2+ and 100% for CIN 3+ lesions in women 30 years and older. In women younger than 30 years, the sensitivity of E6, E7 mRNA for CIN 2+ lesions was 88% for CIN 2+ and 92% for CIN 3+ lesions. Abnormal cytology (≥ASCUS) exhibited a sensitivity of 89% for CIN 2+ and 100% for CIN 3+ in women 30 years and older and 96% sensitivity for CIN 2+ and 93% sensitivity for CIN 3+ in women younger than 30. The specificity of E6, E7 mRNA was >80% for CIN 2+ and CIN 3+ in both groups of women compared to a specificity of abnormal cytology of ASCUS/LSIL triage in women including those younger than 30 years.

To determine the weighted average sensitivity of magnetic resonance (MR) imaging in the prospective detection of acute neck injury and to compare these findings with those of a comprehensive conventional radiographic assessment. Conventional radiography and MR imaging were performed in 199 patients presenting to a level 1 trauma center with suspected cervical spine injury. Weighted sensitivities and specificities were calculated, and a weighted average across eight vertebral levels from C1 to T1 was formed. Fourteen parameters indicative of acute injury were tabulated. Fifty-eight patients had 172 acute cervical injuries. MR imaging depicted 136 (79%) acute abnormalities and conventional radiography depicted 39 (23%). For assessment of acute fractures, MR images (weighted average sensitivity, 43%; CI: 21%, 66%) were comparable to conventional radiographs (weighted average sensitivity, 48%; CI: 30%, 65%). MR imaging was superior to conventional radiography in the evaluation of pre- or paravertebral hemorrhage or edema, anterior or posterior longitudinal ligament injury, traumatic disk herniation, cord edema, and cord compression. Cord injuries were associated with cervical spine spondylosis (P < .05), acute fracture (P < .001), and canal stenosis (P < .001). MR imaging is more accurate than radiography in the detection of a wide spectrum of neck injuries, and further study is warranted of its potential effect on medical decision making, clinical outcome, and cost-effectiveness.

Full Text Available El artículo se propone explorar algunas características de la visión que las mujeres tienen respecto a su sexualidad, ya que existe información que vincula la cultura sexual de la población con la incidencia del cáncer cérvico uterino. Se exploran la valorización del placer sexual, del ejercicio de la sexualidad tras la menopausia, y las formas de prevenir el cáncer cervical, a través de las respuestas de un grupo de mujeres beneficiarias de Consultorios de Atención Primaria de Santiago de Chile, atrasadas en su examen de Papanicolaou por lo menos un año. Se observa que la valoración expresada por las mujeres de su sexualidad es más positiva que en estudios anteriores en Chile, y que hay disposición de las mujeres a aprender más sobre su cuerpo, aún cuando un grupo minoritario mantiene visiones negativas sobre la sexualidad. Esto abre perspectivas para una acción educativa de los servicios de salud, referida no sólo a mejorar las coberturas del examen de Papanicolaou, sino a mejorar la calidad de vida de las mujeres.The purpose of the study is to explore some characteristics of women's perspectives on their sexuality, as there is information that associates the population's sexual culture with the incidence of cervical cancer. The value of sexual pleasure, sexual activity after menopause, and ways of preventing cervical cancer are explored. Data were obtained from a group of women attending primary care clinics in Santiago, Chile, and who were at least a year late for their Pap smear. The value women ascribed to sexuality was more positive than in previous studies performed in Chile. Women want to learn more about their bodies, although a minority still have negative perspectives concerning their sexuality. These results offer health services the opportunity to carry out educational activities with the purpose not only of increasing the number of women who have Pap smears but also of improving their quality of life.

Resection of cervical vagal schwannoma via a post-auricular approach.

Roh, Jong-Lyel

2006-03-01

Cervical vagal schwannomas are extremely rare and gross total resection is the standard treatment modality. However, because the conventional cervical approach leaves an incision scar in a visible area, other approaches need to be developed for young women who want the postoperative scar to be invisible. A 28-year-old female underwent complete resection of a 4x4 cm tumor in her right upper neck via a post-auricular approach using an inverted V-shaped incision along the post-auricular sulcus and hairline. The tumor was a schwannoma originating from the right cervical vagus nerve. Postoperatively, right vocal cord paralysis developed despite careful dissection but completely recovered within 6 months after surgery. The patient was satisfied with an invisible external scar which was hidden by her auricle and hair. A cervical vagal schwannoma can be successfully removed by making an incision in a potentially invisible area.

Infections of face and neck represent serious and potentially life threatening conditions that are sometimes difficult to differentiate from neoplasic tumours, especially in subacute clinical forms. Conventional radiographic techniques offer interest for cervical masses, except Ultra-Sonographic examen, in sites regarding vascular axes, but carries little value for evaluating their spread the into different cervical spaces. On the other hand, C.T. is valuable to precise the location and the extent and to determine its inflammatory nature by studying the fats and the aponeurosis around it. It helps in the analysis of associated adjacent signs: soft tissue swelling, extensive obliteration of adjacent fats, swelling of cervical aponeurosis, thickening of adjacent muscles. These findings are documented by the study of fourteen patients, admitted in St-Antopine hospital. All abcesses, except one, were easy to diagnose because of their low central attenuation. False negative cases are possible and noted by other authors. So, in absence of response to appropriate therapy, surgery is necessary to eliminate a misdiagnosed abcess. Furthermore, it's sometimes possible to suspect an etiology (foreign body, tuberculosis) [fr

Objective To compare the accuracy of liquid based cytology using the computerised ThinPrep Imager with that of manually read conventional cytology. Design Prospective study. Setting Pathology laboratory in Sydney, Australia. Participants 55 164 split sample pairs (liquid based sample collected after conventional sample from one collection) from consecutive samples of women choosing both types of cytology and whose specimens were examined between August 2004 and June 2005. Main outcome measures Primary outcome was accuracy of slides for detecting squamous lesions. Secondary outcomes were rate of unsatisfactory slides, distribution of squamous cytological classifications, and accuracy of detecting glandular lesions. Results Fewer unsatisfactory slides were found for imager read cytology than for conventional cytology (1.8% v 3.1%; Pcytology (7.4% v 6.0% overall and 2.8% v 2.2% for cervical intraepithelial neoplasia of grade 1 or higher). Among 550 patients in whom imager read cytology was cervical intraepithelial neoplasia grade 1 or higher and conventional cytology was less severe than grade 1, 133 of 380 biopsy samples taken were high grade histology. Among 294 patients in whom imager read cytology was less severe than cervical intraepithelial neoplasia grade 1 and conventional cytology was grade 1 or higher, 62 of 210 biopsy samples taken were high grade histology. Imager read cytology therefore detected 71 more cases of high grade histology than did conventional cytology, resulting from 170 more biopsies. Similar results were found when one pathologist reread the slides, masked to cytology results. Conclusion The ThinPrep Imager detects 1.29 more cases of histological high grade squamous disease per 1000 women screened than conventional cytology, with cervical intraepithelial neoplasia grade 1 as the threshold for referral to colposcopy. More imager read slides than conventional slides were satisfactory for examination and more contained low grade cytological

Locoregional anaesthetic techniques can facilitate certain surgeries being performed under standing procedural sedation. The second and third spinal cervical nerves (C2, C3) are part of the cervical plexus and provide sensory innervation to the peri-laryngeal structures in people; block of these nerves might permit laryngeal lateralisation surgery in horses. To describe the anatomical basis for an ultrasound-guided cervical plexus block in horses. To compare this block with conventional local anaesthetic tissue infiltration in horses undergoing standing prosthetic laryngoplasty. Cadaveric study followed by a double-blinded prospective clinical trial. A fresh equine cadaver was dissected to characterise the distribution of C2 and C3 to the perilaryngeal structures on the left side. A second cadaver was utilised to correlate ultrasound images with the previously identified structures; a tissue marker was injected to confirm the feasibility of an ultrasound-guided approach to the cervical plexus. In the clinical study, horses were assigned to two groups, CP (n = 17; cervical plexus block) and INF (n = 17; conventional tissue infiltration). Data collection and analyses included time to completion of surgical procedure, sedation time, surgical field conditions and surgeon's perception of block quality. We confirmed that C2 and C3 provided innervation to the perilaryngeal structures. The nerve root of C2 was identified ultrasonographically located between the longus capitis and the cleidomastoideus muscles, caudal to the parotid gland. The CP group was deemed to provide better (Pblock is a viable alternative to tissue infiltration and it improves the surgical field conditions. © 2018 EVJ Ltd.

According to the third cancer plan, organised screening (OS) of cervical cancer (CC) among women aged 25-65 years should be implemented in France in the forthcoming years. The most efficient way to implement OS in the French healthcare system is yet to be determined. A microsimulation model was developed adopting a collective 'all payers' perspective. A closed cohort of women eligible for CC screening and representative in terms of age and participation in individual screening (IndScr) by annual Papanicolaou (Pap) testing every 3 years was modelled on a lifetime horizon. Different OS strategies, additive to IndScr with a 61.9% participation rate based on mailed invitations to non-participant women to perform OS were assessed. Similar modalities were applied to OS and IndScr participants. Strategies implied different screening tests (Papanicolaou (Pap) test, human papillomavirus (HPV) test and p16/Ki67 double staining) and OS periodicity. Compared with IndScr only, all OS strategies were associated with decreased cancer incidence/mortality (from 14.2%/13.5% to 22.9%/25.8%). Most strategies generated extra costs ranging from €37.9 to €1607 per eligible woman. HPV testing every 10 and 5 years were cost saving. HPV tests every 10 and 5 years were the most efficient strategies, generating more survival at lower costs than Pap-based strategies. Compared to IndScr only, an HPV test every 10 years was cost saving. The most effective strategies were p16/Ki67 as primary or HPV positive confirmation tests, with respective incremental cost-effectiveness ratios of €6 541 250 and €101 391 per life year. Pap-based strategies generated intermediary results. OS strategies based on the HPV test appear highly efficient. However, our results rely on the assumption that women and practitioners comply with the recommended OS periodicities (3, 5, 10 years). Implementing these OS modalities will require major adaptations to the current CC screening organisation. Pap test

To compare Papanicolaou (Pap) and May-Grünwald Giemsa (MGG) stain as 2 techniques for staining for buccal mucosal cells to detect micronuclei (MN) infield studies. Eighty cytologic smears (2 per individual) were taken from the buccal mucosa of 40 cigarette smokers recruited at a rural village in Egypt. Forty smears were stained with Pap stain and 40 with MGG stain. All were assessed for cellularity and scored for MN. Pap stain was faster and easier to process and transport in the field study than was MGG stain. Regarding MGG smears, bacteria and cell debris masked the MN as compared to Pap smears, in which the fixative destroyed the bacteria and made the cell boundaries clearly demarcated. Using Pap stain, MN were seen easily in transparent cytoplasm. Pap stain is the preferred method infield studies for scoring and detecting MN in cells of buccal mucosa.

The cervical lead shield was compared with the conventional lead apron with regard to efficiency of protection against radiation during a full-month survey (fourteen periapical and two bitewing radiographs). The study was performed on a Temex tissue-equivalent human phantom, and thermoluminescent dosimetry was used to measure radiation absorption in the ovaries, testes, and thyroid gland areas. Results showed that the cervical shield significantly reduces the amount of radiation to the skin in all three areas and is equally as effective as the combination of lead apron and thyroid shield. It is therefore recommended as a protective measure during intraoral radiography

Purpose: To compare the radiation dose of whole-body multislice CT (MSCT) and conventional radiography with organ-specific CT in polytrauma. Materials and Methods: The whole-body MSCT encompassing brain, neck and midface, chest, abdomen and pelvis was performed on a Somatom Volume Zoom (Siemens). Conventional radiography consisted of chest and cervical, thoracic and lumbar spine in two views as well as pelvis. Polymat, Siemens. Three combinations of organ specific CT were chosen: CT examination of (1) head and cervical spine, (2) head, cervical spine and chest, (3) head, cervical spine and abdomen. The effective doses of whole-body MSCT and conventional radiography with organ-specific CT were calculated. Results: Effective doses were 20 mSv for whole-body MSCT, 2 mSv for conventional x-ray, and 5 mSv for combination (1), 8 mSv for combination (2) and (3) 16 mSv for combination (3) of the organ-specific CT. The ratio of radiation dose between whole-body MSCT and radiography was 10: 1. This ratio was reduced to 3: 1, 2: 1 and 1: 1 when a combination of radiography and CT was performed. Conclusions: Whole-body MSCT in polytrauma compared to conventional radiography with organ-specific CT induces a threefold increased dose in unfavorable situations and no increased dose in favorable situations. Nevertheless, routine use of whole-body MSCT should be critically evaluated and should be adapted to the clinical benefit. (orig.) [de

Different US practice guidelines have conflicting recommendations for when women should return after a screening result of human papillomavirus (HPV)-negative with an equivocal Papanicolaou (Pap) result of atypical squamous cells of undetermined significance (ASC-US) (ie, return in either 3 or 5 years). One way to determine management is to compare the risk of precancer/cancer after an HPV-negative/ASC-US result with the risks after other negative screening results. For example, if the risk after an HPV-negative/ASC-US result was similar to the risk after a negative Pap test, a 3-year return would be preferred because guidelines agree that women with negative Pap test results should return in 3 years. Alternatively, if the risk after an HPV-negative/ASC-US result is similar to that after a cotest-negative result (HPV negative/Pap test negative), a 5-year return would be preferred because guidelines agree that women testing cotest negative should return in 5 years. The authors compared risks of cervical intraepithelial neoplasia of grade 3 or higher (CIN3+) and cervical cancer among women aged 30 years to 64 years at Kaiser Permanente Northern California with the following test results from 2003 through 2012: 17,191 women testing HPV negative/ASC-US; 980,268 women testing Pap test negative (regardless of HPV result); and 892,882 women testing cotest negative. The 5-year CIN3+ and cancer risks after an HPV-negative/ASC-US result were closer to the risks after a negative Pap test result (CIN3+: 0.48% vs 0.31% [P =.0019]; and cancer: 0.043% vs 0.031% [P =.4]) than after a negative cotest (CIN3+: 0.48% vs 0.11% [P<.0001]; and cancer: 0.043% vs 0.014% [P =.016]). Women testing HPV negative/ASC-US were found to have precancer/cancer risks that were more closely aligned with women with negative Pap test results, suggesting that women testing HPV negative/ASC-US should be managed similarly to women testing negative on Pap tests with a 3-year return for screening. © 2014

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.

The aim of this study was to review published studies to identify and describe barriers to Papanicolaou (Pap) smear screening among women in sub-Saharan Africa. Guided by Cooper's integrative review methodology, studies published between 2006 and 2015 were identified by searching electronic databases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, MEDLINE, ProQuest, and PsycINFO using specified search terms. Using this strategy, 224 articles were identified and screened for duplication and by reading titles, abstracts, and full texts. Seventeen articles met the inclusion criteria and were appraised using relevant tools for qualitative and quantitative designs. No relevant articles published in 2006, 2007, and 2014 were found. All 17 articles had good methodological quality and were included in the review. The studies were from 10 sub-Saharan countries and from different settings. Content analysis of the data revealed three major themes coded as client, provider, and system barriers. The most common client barriers were lack of knowledge and awareness about Pap smear screening, fear of cancer, belief of not being at risk for cervical cancer, and that a Pap smear is not important unless one is ill and cultural or religious factors. Provider barriers were failure to inform or encourage women to screen. Major system barriers were unavailability and inaccessibility of the Pap test. The review provided evidence of barriers to Pap smear screening among sub-Saharan women. Although there were some variations from country to country, sub-Saharan countries share similar constraints to Pap smear screening. These findings have important implications for practice and policy. Understanding the client, provider, and system barriers to cervical cancer screening could guide development of effective interventions. © 2016 Sigma Theta Tau International.

Full Text Available Objective. The objectives were to show the feasibility of a wireless microelectromechanical system inertial measurement unit (MEMS-IMU to assess the time-domain characteristics of cervical motion that are clinically useful to evaluate cervical spine movement. Methods. Cervical spine movements were measured in 18 subjects with wireless IMUs. All rotation data are presented in the Euler angle system. Amount of coupling motions was evaluated by calculating the average angle ratio and the maximum angle ratio of the coupling motion to the primary motion. Reliability is presented with intraclass correlation coefficients (ICC. Results. Entire time-domain characteristics of cervical motion were measured with developed MEMS-IMU system. Cervical range of motion (CROM and coupling motion range were measured with high ICCs. The acquired data and calculated parameters had similar tendency with the previous studies. Conclusions. We evaluated cervical motion with economic system using a wireless IMU of high reliability. We could directly measure the three-dimensional cervical motion in degrees in realtime. The characteristics measured by this system may provide a diagnostic basis for structural or functional dysfunction of cervical spine. This system is also useful to demonstrate the effectiveness of any intervention such as conventional medical treatment, and Korean medical treatment, exercise therapy.

We review the pathophysiology and imaging findings of acute traumatic spinal cord injury (SCI), cervical spondylotic myelopathy, and briefly review the much less common cord herniation as a unique cause of myelopathy. Acute traumatic SCI is devastating to the patient and the costs to society are staggering. There are currently no "cures" for SCI and the only accepted pharmacologic treatment regimen for traumatic SCI is currently being questioned. Evaluation and prognostication of SCI is a demanding area with significant deficiencies, including lack of biomarkers. Accurate classification of SCI is heavily dependent on a good clinical examination, the results of which can vary substantially based upon the patient׳s condition or comorbidities and the skills of the examiner. Moreover, the full extent of a patients׳ neurologic injury may not become apparent for days after injury; by then, therapeutic response may be limited. Although magnetic resonance imaging (MRI) is the best imaging modality for the evaluation of spinal cord parenchyma, conventional MR techniques do not appear to differentiate edema from axonal injury. Recently, it is proposed that in addition to characterizing the anatomic extent of injury, metrics derived from conventional MRI and diffusion tensor imaging, in conjunction with the neurological examination, can serve as a reliable objective biomarker for determination of the extent of neurologic injury and early identification of patients who would benefit from treatment. Cervical spondylosis is a common disorder affecting predominantly the elderly with a potential to narrow the spinal canal and thereby impinge or compress upon the neural elements leading to cervical spondylotic myelopathy and radiculopathy. It is the commonest nontraumatic cause of spinal cord disorder in adults. Imaging plays an important role in grading the severity of spondylosis and detecting cord abnormalities suggesting myelopathy. Copyright © 2016 Elsevier Inc. All rights

suspected cervical neoplasia and to compare it with young adult women. METHODS: a cross-sectional, retrospective study that analyzed 366 medical records of females referred to clarify diagnosis of the suspected cervical neoplasia. The patients had been classified into two groups defined by age. The Adolescent group was composed of 129 females between 13 and 19 years and the Adult group was composed of 237 females between 20 and 24 years. Data were analyzed statistically by the prevalence ratio (PR, respective confidence intervals (CI at 95% for each variable, chi2 test, or Fisher exact test used to compare proportion. RESULTS: the first sexual intercourse coitarche occurred on average at 15.0 years in the Adolescent group and 16.6 years in the Adult group. The possibility of diagnosis of cytological alterations in the first Papanicolaou smears (PR=2.61; CI 95%: 2.0-3,4, the condition of non-clarified cervical intraepithelial neoplasia (CIN (PR=1.78; CI 95%: 1.26-2,52, and the colposcopic impressions of low grade (PR=1.42; CI 95%: 1.08-1.86 were statistically significant in the Adolescent group. The histopathologic analysis did not show differences at any grade of CIN. However, two cases of microinvasive carcinoma, one in each group, and three cases of clinical invasive carcinoma in the Adult group were identified. CONCLUSION: our study suggests that cervical cancer is rare among adolescents, but we verified that alterations associated with it occurred even in younger women. The evaluation of cervical intraepithelial neoplasia with the careful application of the same tools used for adult women was appropriate also in adolescence.

Cervical spinal canal narrowing and cervical neurologi-cal injuries

Full Text Available 【Abstract】Cervical spinal canal narrowing can lead to injury of the spinal cord and neurological symptoms in-cluding neck pain, headache, weakness and parasthesisas. According to previous and recent clinical researches, we investigated the geometric parameters of normal cervical spinal canal including the sagittal and transverse diameters as well as Torg ratio. The mean sagittal diameter of cervical spinal canal at C 1 to C 7 ranges from 15.33 mm to 20.46 mm, the mean transverse diameter at the same levels ranges from 24.45 mm to 27.00 mm and the mean value of Torg ratio is 0.96. With respect to narrow cervical spinal canal, the following charaterstics are found: firstly, extension of the cervical spine results in statistically significant stenosis as compared with the flexed or neutral positions; secondly, females sustain cervical spinal canal narrowing more easily than males; finally, the consistent narrowest cervical canal level is at C 4 for all ethnicity, but there is a slight variation in the sagittal diameter of cervical spinal stenosis (≤14 mm in Whites, ≤ 12 mm in Japanese, ≤13.7 mm in Chinese. Narrow sagittal cervical canal diameter brings about an increased risk of neurological injuries in traumatic, degenerative and inflam-matory conditions and is related with extension of cervical spine, gender, as well as ethnicity. It is hoped that this re-view will be helpful in diagnosing spinal cord and neuro-logical injuries with the geometric parameters of cervical spine in the future.

Papanicolaou (Pap) testing rates among Chinese women remain low compared with their Caucasian counterparts despite extensive efforts to raise awareness of the importance of regular screening. We examined three potential predictors of Pap testing behaviour in Chinese women: acculturation, cervical cancer screening belief accuracy, and intergenerational transmission. Caucasian (n = 78) and Chinese (n = 93) female university students and their mothers completed questionnaires concerning acculturation, Pap testing beliefs, and behaviours. Ethnic group comparisons revealed that Chinese daughters and mothers had lower Pap testing rates and less accurate beliefs regarding cervical cancer screening. Among women who had had at least one Pap test, there was no ethnic difference in the proportion of women who adhered to the recommended screening frequency. Among the Chinese women, lower heritage acculturation was correlated with higher cancer screening belief accuracy in both the daughters and their mothers. Maternal Pap testing behaviour was predicted by level of cancer screening belief accuracy, whereas daughters' Pap testing behaviour was predicted by previous experience of sexual intercourse and heritage acculturation. No intergenerational transmission of Pap testing beliefs or behaviours was found. The accuracy of cancer screening beliefs, level of acculturation and experience of sexual intercourse may be predictors of Pap testing behaviour in Chinese women. Contrary to our prediction, we found no support for intergenerational transmission, suggesting that Pap testing beliefs and behaviours of Chinese women are independent of the beliefs and behaviours of their mothers.

2014-01-01

Full Text Available Background & objectives: Staging of cervical carcinoma is done clinically using International Federation of Obstetrics and Gynecology (FIGO guidelines. It is based on physical examination findings and also includes results of biopsy, endoscopy and conventional radiological tests like chest radiograph, intravenous urography and barium enema. These conventional radiological investigations have largely been replaced by computed tomography (CT and magnetic resonance imaging (MRI at present. FIGO staging system does not consider CT and MRI mandatory; however, use of these modalities are encouraged. This prospective study was conducted to determine the role of CT in staging work up in women diagnosed with cervical carcinoma. Methods: Fifty three women diagnosed with cervical carcinoma were evaluated with contrast enhanced CT scan of abdomen and pelvis. CT scan images were especially evaluated to determine tumour size, invasion of parmetrium, pelvic walls, rectum, urinary bladder and ureters, pelvic or retroperitoneal lymphadenopathy and distant metastases. CT findings were associated with clinical findings and staging, including findings from cystoscopy and sigmoidoscopy. Results: There was a poor agreement between clinical and CT staging of cervical carcinoma. Primary tumour was demonstrated on CT in 36 (70% of 53 patients. CT underestimated the parametrial, vaginal and pelvic wall invasion when compared with physical examination. CT overestimated the urinary bladder and rectal invasion when compared with cysto-sigmoidoscopy, however, CT had 100 per cent negative predictive value (NPV to exclude bladder and rectal involvement. CT detection of lymph node enlargement and lung metastases influenced the management. Interpretation & conclusions: Our findings show that CT scan does not reliably correlate with clinical FIGO staging of cervical cancer. However, it can detect urinary obstruction as well as nodal or distant metastases and thus improves the

Full Text Available p16 immunohistochemistry is used to evaluate for HPV-associated cervical intraepithelial neoplasia. The diagnostic performance of p16 in HIV infection is unclear.Between June-December 2009, HIV-infected women underwent Papanicolaou (Pap smear, human papillomavirus (HPV testing, visual inspection with acetic acid (VIA, and colposcopy-directed biopsy as the disease gold standard at a HIV clinic in Kenya. Pap smears were evaluated for p16 expression. Sensitivity, specificity, positive predictive value (PPV, and area under the receiver operating characteristic curve (AUC of p16 to detect CIN2/3 on histology and the impact of immunosuppression and ART was assessed.Of 331 cervical samples with p16 expression, p16 sensitivity and specificity to detect CIN2/3 was 54.1% and 72.4% respectively, which was lower than Pap and HPV in sensitivity, but higher in specificity than Pap, HPV, and VIA. Combining tests and p16 reduced sensitivity and increased specificity of Pap from 90.5% to 48.7% and 51.4% to 81.7%; of VIA from 59.5% to 37.8% and 67.6% to 89.9%; and of HPV from 82.4% to 50.0% and 55.3% to 84.8%. Combination p16 increased the PPV of Pap from 34.9% to 43.4%; of HPV from 34.7% to 48.7%; and VIA from 34.9% to 51.9%. Adjunctive p16 did not change AUC (P>0.05. P16 performance was not altered by immunosuppression or ART use. Combining p16 with HPV and VIA reduced the variation in HPV and VIA performance associated with CD4 and ART.As an adjunctive test in HIV-infected women, p16 immunohistochemistry increased specificity and PPV of HPV and VIA for CIN2/3, and was not altered in performance by immunosuppression, ART, or age.

Full Text Available Conventional, cytology based Cervical cancer screening programmes used in the developed world is often not practical in developing countries. Training of health care work force on a feasible, low-tech, screening methods is urgently needed in low resource settings. Twenty providers including doctors and nurses participated in a 2-days training workshop organized by a Community Health Center in rural South India. The pre-post-training assessment showed significant improvement in knowledge about cervical cancer, ‘low tech’ screening, treatment options and counseling among the participants.  Twenty volunteers screened at the workshop, 2 women (10% tested positive and one had CINIII lesion and the other had cervical cancer stage IIIB. After the training, the participants felt confident about their ability to counsel and screen women for cervical cancer.

Barriers to adoption of recent technology in cervical screening

Full Text Available Abstract The Pap smear is one of the modern success stories in the field of preventive medicine. Since its introduction as a screening test, there has been a dramatic reduction in the incidence of cervical cancer. However, the search for a better screening test continues. The new technologies, including liquid-based cytology (LBC, Human Papilloma Virus (HPV testing and automated or machine-assisted screening have been introduced. However, there is continuous debate about whether society's limited resources are better spent on reaching the underserved rather than on these technologies. Another question is whether these technologies create yet another kind of disparity in delivering preventive care. For example, despite the wide use of LBC (99% of tests submitted to our laboratory are LBC, conventional Pap smears are still used to screen/follow up some women. It is not clear why some providers continue to prefer conventional smear over LBC and what are the barriers for adopting LBC in cervical cancer screening. We hypothesize the lower cost of conventional compared to LBC Pap testing, patient's lower socio-economic indices, a patient's medical history and provider's subspecialty/training all appear to play a role in the choice of using conventional Pap testing rather than LBC. Unintentionally, this choice results in repeat testing, delayed treatment and potentially higher costs than intended. The ultimate goal of this review article is to understand and explore possible barriers and disparities to adopting new technology in cancer screening.

A very rare case of HPV-53-related cervical cancer, in a 79-year-old woman with a previous history of negative Pap cytology.

The introduction of organized cervical cancer (CC) screening programs has drastically reduced the prevalence of CC. However the incidence is still too high, especially among elderly women. All guidelines strongly recommend a regular Papanicolaou (Pap) testing for young and middle-aged patients. On the other hand, many international professional societies no longer advise screening in women who have undergone hysterectomy, and in women aged 65 years and above, who have a previous history of regular Pap smears. Here we report the case of poorly differentiated CC, involving the pelvic lymph nodes and urinary bladder, occurring in a 79-year-old woman who regularly underwent Pap tests, with no reported cytological abnormalities. In this very rare case, the CC cells, as well as cells from metastatic lymph nodes and cells from urinary specimens, molecularly showed human papilloma virus (HPV)-53. With the limitations of a single case, this report brings important information to prevent CC in elderly patients: the utility of molecular tests to increase sensitivity of Pap smears in postmenopausal women; the importance of HPV-53 as one of the four "emergent" genotypes having a possible role in oncogenesis; and the presence of HPV-53 in lymph node metastases from cervical carcinoma, which would support the role of this virus in the maintenance of malignant status.

To test the hypothesis that improvement of cervical lordosis in cervical spondylotic radiculopathy (CSR) will improve cervical spine flexion and extension end range of motion kinematics in a population suffering from CSR. Thirty chronic lower CSR patients with cervical lordosis lordosis (p lordosis in the study group was associated with significant improvement in the translational and rotational motions of the lower cervical spine. This finding provides objective evidence that cervical flexion/extension is partially dependent on the posture and sagittal curve orientation. These findings are in agreement with several other reports in the literature; whereas ours is the first post treatment analysis identifying this relationship.

Guilcher, Sara J T; Newman, Alice; Jaglal, Susan B

2010-01-01

Previous qualitative and survey studies have suggested women with spinal cord injury (SCI) are screened less often for cervical cancer compared with the general population. We investigated whether cervical cancer screening rates differ between population-based women with and without traumatic SCI, matched for age and geography. A double cohort design was used, comparing women with SCI to the general population (1:4) using administrative data for Ontario, Canada. Women with SCI, identified using the Discharge Abstract Database for the fiscal years 1995-1996 to 2001-2002, were female residents of Ontario between the ages of 25 and 66, admitted to an acute care facility with a traumatic SCI (ICD-9 CM code 806 or 952). Women in the general Ontario population were randomly matched by age and geography. Screening rates were calculated from fee codes related to Papanicolaou (Pap) smear tests for a 3-year period preinjury and postinjury. There were 339 women with SCI matched to 1506 women in the general Ontario population. Screening rates pre-SCI were 55% for women with SCI and 57% during this same time period for matched women in the general population; post-SCI rates were 58% for both the two groups. Factors predicting the likelihood of receiving a Pap test for SCI cases included younger age and higher socioeconomic status. Utilization data suggest that there are no significant differences in screening rates for women with SCI compared with the general population. However, screening rates for women with SCI were significantly influenced by age as well as income.

2016-01-01

Full Text Available Introduction: Cervical cancer is the most common malignancy diagnosed during pregnancy. In developing countries where organized screening programmes are lacking, antenatal clinics may provide an opportunity for screening. Objectives: The aim of this study was to analyse the prevalence and management of abnormal cervical cytology in pregnancy. Methodology: This was a prospective study conducted at the Meenakshi Medical College and RI, Kancheepuram, India, from July 2013 to June 2014. Convenience sampling technique was used. After adequate counselling, 300 antenatal mothers between 12 and 34 weeks of gestation were screened with conventional Pap smear. Colposcopy directed biopsy was taken where and when necessary. Results: Among the 300 pregnant women, 90 (30% were primigravidae and 210 (70% were multigravidae. 80% were between 21 and 30 years of age. 290 (96.6% women have never had a pap smear in the past. Conventional Pap smear was taken at 21 weeks of gestation in 20% of cases. ASCUS , LSIL and HSIL were reported in one case each. In those with LSIL and HSIL , Colposcopy directed biopsy was reported as CIN 1 and CIN 2 respectively. These two cases were kept under observation during the antenatal period. The CIN II lesion persisted on postpartum follow up and was treated with LLETZ. Conclusion: In countries like India Pap smear screening during pregnancy is worthwhile and the antenatal clinics provide ample opportunities for the screening.

The Bethesda system (TBS) has been used for cervical cytological diagnosis in Japan since 2008. Evaluation of specimen adequacy is the most important aspect of quality assurance and for precise diagnosis in TBS. A systematic review and meta-analysis were carried out to assess the unsatisfactory specimen rate in the primary cervical cancer screening setting in Japan. Ovid Medline and Ichushi-Web databases were searched from inception through to May 2017. Prospective and retrospective studies that reported the proportion of unsatisfactory specimens in healthy asymptomatic Japanese women in a cervical cancer screening program were eligible for inclusion; 17 studies were included in the meta-analysis. The random-effects model meta-analysis calculated summary estimates of the unsatisfactory rate of 0.60% (95% confidence interval [CI], 0.18-1.96%; I 2 = 99%) for conventional cytology and 0.04% (95% CI, 0.00-0.35%; I 2 = 99%) for liquid-based cytology (LBC). However, comparative results between conventional and liquid-based cytology, based on four direct and nine comparative studies, showed no significant difference (summary odds ratio = 3.5 × 10 -2 favoring LBC [95% CI, 6.9 × 10 -4 -1.7]; I 2 = 98%). In the subgroup analyses and meta-regressions, use of non-cotton devices for conventional cytology and use of a particular platform for LBC were associated with lower unsatisfactory rates. Meta-regression also suggested chronological improvement in unsatisfactory rates for both tests. In Japanese cervical cancer screening programs, conventional cytology remains prevalent. Future research needs to focus on evaluating the impact of screening programs using LBC by comparing the accuracy, performance, and cost-effectiveness with conventional cytology in the Japanese population. © 2018 The Authors.

Full Text Available Objective. To evaluate cytology laboratories and the performance of cytotechnologists for establishing efficient external quality control for Mexico's National Program for the Prevention and Control of Cervical Cancer. Material and Methods. During January and February 1998, an on-site evaluation of all cytology laboratories of the Ministry of Health found that only 70% of the microscopes were in adequate working conditions, reagents were out of date, and working conditions were sub-optimal. A program for external quality control based on proficiency testing was established for cytotechnologists. Fifty slide sets with 20 Papanicolaou slides and 10 photographic slides were prepared. The sets were given to the cytotechnologists for evaluation and again one year later by courier. Results. Twenty-one percent of microscopes were repaired and 9% replaced; reagents were distributed and laboratory facilities improved. Only 16% of cytotechnologists passed the initial proficiency test. Cytotechnologists received a refresher training course: one year later 67% of them passed the proficiency test. To ascertain that each slide was correctly diagnosed, 41 sets were rescreened by expert cytopathologists or cytologists and their diagnoses compared to the original ones. Thirty-seven sets had 86% to 96% concordance. Conclusions. This new system for external quality control of cervical cytology allowed the opportune and reliable evaluation of the performance of cytotechnologists.Objetivo.

Purpose: The squamous cell carcinoma (SCC) antigen is still considered the most accurate serologic tumor marker in cervical carcinoma. We assessed the contribution of the SCC assay to the detection of recurrences in patients treated with radiotherapy. Methods and Materials: The pattern of recurrence and follow-up data were prospectively recorded for 135 patients. Of the 135 patients, 103 (76.3%) had primary cervical carcinoma and 32 (23.7%) had already experienced disease recurrence that had been successfully treated with surgery (n = 2), surgery plus radiotherapy (n = 2), radiotherapy (n = 5), or concomitant chemoradiotherapy (n = 23). The follow-up evaluations (chest X-ray, abdominopelvic magnetic resonance imaging, gynecologic examination with colposcopy, Papanicolaou smear, and SCC assay) were performed at 6-month intervals; the evaluation was done earlier if recurrent disease was suspected. The median follow-up time was 29 months (range, 6-131). The SCC serum levels were assayed, and a cost analysis was done. Results: A total of 481 SCC determinations were performed. Of the 135 patients, 43 (31.8%) experienced disease recurrence. The SCC levels were higher in those with recurrent disease than in the disease-free patients. Elevation of SCC was documented in 34 (79.1% sensitivity) of 43 recurrences before symptoms appeared. Of the 38 patients with serum SCC elevation, 34 developed a recurrence (positive predictive value, 89.5%). Of the 97 patients with negative SCC serum levels, 88 had negative findings at the clinicoradiologic evaluation (negative predictive value, 90.7%). A simplified approach (SCC plus gynecologic examination) was evaluated. Compared with the complete follow-up program, the rate of missed recurrence was 2.2%. The total projected cost per patient for 5 years of follow-up for the simplified procedure was approximately 12.2-fold lower than the standard approach. Conclusions: Our results have shown that a simplified diagnostic approach, including

Abstract Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis. PMID:25761188

Full Text Available OBJECTIVE: To carry out a situational analysis of cervical cancer prevention activities in Argentina, specifically regarding (a the organizational framework of cervical cancer prevention activities; (b Pap-smear coverage; (c cytology laboratory organization; and (d follow-up/treatment of women with abnormal lesions. METHODS: A situational analysis of provincial cervical cancer programs using data from an ad-hoc questionnaire sent to the leaders of cervical cancer prevention programs in Argentina's 24 provinces. In addition, the provinces' program guidelines, statistical reports, laws, and program regulations were reviewed and certain key leaders were personally interviewed. RESULTS: Data were obtained for 19 of Argentina's 24 provinces. Four of the 19 provinces had no formal program framework. Conventional cytology was the most commonly used screening test. Screening was mainly opportunistic. The recommended interval between normal tests was 3 years in most provinces. The eligible age for screening ranged from 10-70 years of age; however, annual or biannual screening was the usual practice after becoming sexually active. None of the provincial programs had data available regarding Pap-smear coverage. Most of the cytology laboratories did not have a quality control policy. The number of smears read varied greatly by laboratory (650-24 000 per year. A log of events related to screening and treatment did not exist in most provinces. CONCLUSIONS: Screening in Argentina is mainly opportunistic, characterized by an estimated low coverage, coexisting with over-screening of women with access to health services, and an absence of quality control procedures. Policies for cervical cancer screening in the provinces vary and, most often, deviate from the national recommendation of one Pap smear every 3 years for women 35-64 years of age. Ensuring compliance with national program guidelines is an essential step toward significantly reducing the burden of

Computerized tomography (CT) of the cervical spinal column was carried out in 39 patients using a GE.CT/T or Toshiba TCT60A scanner. There were 22 cervical disk lesions, 4 spinal neoplasms, 5 narrow spinal canals with or without ossification of the posterior longitudinal ligament, 2 syringomyelias, 5 traumas, and one Arnold-Chiari malformation. In all the patients, tomography was done after conventional spinal X-ray studies. The correlation between the CT findings and conventional X-ray films revealed the excellent capability of the CT. The measurement of the midline sagittal diameter of the spinal canal in the patient with the narrowest canal in this series showed 7.4 mm when done by CT and 9.6 mm when done by the conventional plain film at the C/sub 5/ level. To ascertain the precise sagittal diameter of the cord itself, CT myelography is indispensable after the intrathecal injection of metrizamide A; metrizamide CT myelogram is useful in determining the nature of the disease, the risk of and best approach to surgery, and the evaluation after a surgical procedure. Although the range of motion of cervical joints and intervertebral foramen are visible with the conventional films, the size of the spinal tumors, the degree of bony change, and the tumor extension to the paraspinal connective tissue can be precisely demonstrated only by CT. A CT study of the spine is a simple procedure and is less likely to produce complication, even with a metrizamide CT myelogram, though there are certain limitations in the examination.

Cancer is one of the contagious diseases that become a public health issue, both in the world and in Indonesia. In the world, 12% of all deaths caused by cancer and is the second killer after cardiovascular disease. Early detection using the IVA is a practical and inexpensive (only requiring acetic acid). However, the accuracy of the method is quite low, as it can not detect the stage of the cancer. While other methods have a better sensitivity than the IVA method, is a method of PAP smear. However, this method is relatively expensive, and requires an experienced pathologist-cytologist. According to the case above, Considered important to make the cancer cervics detector that is used to detect the abnormality and cervical cancer stage and consists of a digital microscope, as well as a computer application based on artificial neural network. The use of cervical cancer detector software and hardware are integrated each other. After the specifications met, the steps to design the cervical cancer detection are: Modifying a conventional microscope by adding a lens, image recording, and the lights, Programming the tools, designing computer applications, Programming features abnormality detection and staging of cancer.

Chan, Dorothy N S; So, Winnie K W

Cervical cancer can be prevented by effective screening using Papanicolaou tests, but the utilization rate is lower among ethnic minorities than in the general population. Understanding the factors influencing minorities' use of such screening can aid the design of an appropriate intervention to increase their uptake rate. The aims of this study were to examine the factors that influence ethnic minority women in using cervical cancer screening and the similarities and differences in associated factors across different groups and to explore the interrelationships between the factors identified. A literature search was conducted using Ovid MEDLINE, Cumulative Index to Nursing and Allied Health Literature Plus, Scopus, PsycINFO, and PubMed. Furthermore, 1390 articles were retrieved, of which 24 met the inclusion criteria. Critical appraisal was performed by means of a quality assessment tool. The findings were summarized in tabular and narrative forms. The findings showed that certain factors commonly affected ethnic minority women's screening behavior, including knowledge, attitude and perceptions, physician's recommendation, quality of care and service, language, and acculturation. Culture-related factors, religion, and acculturation exhibited close interrelationships with the attitude and perceptions factor, resulting in behavioral change. The review sheds light on how common or unique are the factors across ethnic minorities and how these factors interact to influence behavior. Further studies are warranted to develop and test empirically a comprehensive model leading to a better understanding of the interrelationships between multiple factors. The model should be useful in informing policy makers about appropriate resource allocation and in guiding the development of culturally relevant programs to increase screening uptake.

Objective: To evaluate target-volume coverage and organ at risk (OAR) protection achieved with conventional radiotherapy (CRT), three dimensional conformal radiotherapy (3DCRT), and intensity-modulated radiotherapy(IMRT) through dosimetric comparison in patients with cervical cancer after hysterectomy. Methods: The planning CT scans of 10 patients treated with pelvic radiation after hysterectomy for cervical cancer were used to generate CRT, 3DCRT and IMRT plans for this study. Clinical target volume(CTV) was contoured on the individual axial CT slices of every patient. The CTV was then uniformly expanded by 1.0 cm to create the planning target volume (PTV). The small bowel, rectum, bladder, bone marrow, ovaries, and femoral heads were outlined for the organ at risk (OAR) evaluation. The CRT, 3DCRT and IMRT plans were generated using commercial planning software. CRT plan was prescribed to deliver 45 Gy to the reference point, while IMRT and 3DCRT plans were 45 Gy to 95% of the PTV. Isodose line and dose volume histograms(DVH) were used to evaluate the dose distribution in CTV and OAR. Results: For 10 patients, the average volume of CTV receiving the prescribed dose of CRT was significantly lower than 3DCRT(Q=8.27, P<0.01) and IMRT(Q=8.37, P<0.01), respectively. Comparing with the CRT plan, the 3DCRT and IMRT plans notably reduced the volume of bowel at 30 and 45 Gy levels. The IMRT plan significantly spared rectum and bladder at 30 and 45 Gy levels comparing with the CRT (P<0.01) and 3DCRT(P<0.05) plans, while the 3DCRT plan significantly spared rectum and bladder at 45 Gy level comparing with the CRT(P<0.01) plans. For 4 patients with ovarian transposition, the average doses of ovary over 3 Gy were 2 patients with the 3 DCRT and IMRT plans, and 2 with all three plans. Conclusions: IMRT and 3DCRT are superior to CRT in improving dose coverage of target volume and sparing of OAR, while IMRT being the best. The superiority of IMRT and 3DCRT is obvious in sparing

Dynamic magnetic resonance imaging of cervical lymph nodes in patients with oral cancer. Utility of the small region of interest method in evaluating the architecture of cervical lymph nodes

Our purpose was to evaluate the utility of the small region of interest (ROI) method to detect the architecture of cervical lymph nodes and the specificity of time-intensity curves for tissue present in cervical lymph nodes. Specimens were taken from 17 lymph nodes of eight patients (ten sides of the neck) with oral squamous cell carcinoma who underwent dynamic contrast-enhanced magnetic resonance imaging (MRI) and neck dissection between 2005 and 2007 at our hospital. Two methods of constructing time-intensity curves were compared: the conventional method that uses relatively large ROIs, and a new method that uses small ROIs. Curves made with the small ROI method were then compared to histopathological findings for dissected lymph nodes. The small ROI method allowed differences in signal intensity to be discerned at the tissue level, which was not possible with the conventional large ROI method. Curves for normal lymphoid tissue tended to be type I, those for tumor cells tended to be type II, and those for keratinization/necrosis tended to be types III and IV, indicating that time-intensity curves can be specific to tissue type within lymph nodes. The small ROI method was useful for evaluation of the architecture of cervical lymph nodes. (author)

System theory in medical diagnostic devices: an overview.

Science.gov (United States)

Baura, Gail D

2006-01-01

Medical diagnostics refers to testing conducted either in vitro or in vivo to provide critical health care information for risk assessment, early diagnosis, treatment, or disease management. Typical in vivo diagnostic tests include the computed tomography scan, magnetic resonance imaging, and blood pressure screening. Typical in vitro diagnostic tests include cholesterol, Papanicolaou smear, and conventional glucose monitoring tests. Historically, devices associated with both types of diagnostics have used heuristic curve fitting during signal analysis. However, since the early 1990s, a few enterprising engineers and physicians have used system theory to improve their core processing for feature detection and system identification. Current applications include automated Pap smear screening for detection of cervical cancer and diagnosis of Alzheimer's disease. Future applications, such as disease prediction before symptom onset and drug treatment customization, have been catalyzed by the Human Genome Project.

Purpose: Postoperative cervical cancer patients with large target volume and the target shape is concave, treatmented with static intensity-modulated radiotherapy (IMRT) is time consuming. The purpose of this study is to investigate using constant dose rate and gantry speed arc therapy(CDR-CAS-IMAT) on conventional linear accelrator, by comparing with the IMRT technology to evaluate the performance of CDR-CAS-IMAT on postoperative cervical cancer patients. Methods: 18 cervical cancer patients treated with IMRT on Varian 23IX were replanted using CDR-CAS-IMAT. The plans were generated on Oncentra v4.1 planning system, PTV was prescribed to 50.4 Gy in 28 fractions. Plans were evaluated based on the ability to meet the dose volume histogram. The homogeneity index (HI), conformity index (CI) of target volume, the dose of organs at risk, radiation delivery time and monitor units were also compared. SPSS 19.0 software paired T-test analysis was carried out on the two sets of data. Results: Compared with the IMRT plans PTV’s CI (t= 3.85, P =0.001), CTV’s CI, HI, D90, D95, D98, V95, V98, V100 (t=4.21, −3.18, 2.13, 4.65, 7.79, 2.29, 6.00, 2.13, p=0.001, 0.005, 0.049, 0.000, 0.000, 0.035, 0.000, 0.049), and cord D2 and rectum V40 (t=−2.65, −2.47, p= P =0.017, 0.025), and treatment time and MU (t=−36.0, −6.26, P =0.000, 0.000) were better than that of IMRT group. But the IMRT plans in terms of decreasing bladder V50, bowel V30 (t=2.14, 3.00, P =0.048, 0.008) and low dose irradiation volume were superior to that of CDR-CAS-IMAT plans. There were no significant differences in other statistical index. Conclusion: Cervical cancer patients with CDR-CAS-IMAT on Varian Clinical 23IX can get equivalent or superior dose distribution compared with the IMRT technology. IMAT have much less treatment time and MU can reduce the uncertainty factor and patient discomfort in treatment.

Full Text Available Background: It is difficult to visualise the larynx using conventional laryngoscopy in the presence of cervical spine immobilisation. Airtraq® provides for easy and successful intubation in the neutral neck position. Objective: To evaluate the effectiveness of Airtraq in comparison with the Mc Coy laryngoscope, when performing tracheal intubation in patients with neck immobilisation using hard cervical collar and manual in-line axial cervical spine stabilisation. Methods: A randomised, cross-over, open-labelled study was undertaken in 60 ASA I and II patients aged between 20 and 50 years, belonging to either gender, scheduled to undergo elective surgical procedures. Following induction and adequate muscle relaxation, they were intubated using either of the techniques first, followed by the other. Intubation time and Intubation Difficulty Score (IDS were noted using Mc Coy laryngoscope and Airtraq. The anaesthesiologist was asked to grade the ease of intubation on a Visual Analogue Scale (VAS of 1-10. Chi-square test was used for comparison of categorical data between the groups and paired sample t-test for comparison of continuous data. IDS score and VAS were compared using Wilcoxon Signed ranked test. Results: The mean intubation time was 33.27 sec (13.25 for laryngoscopy and 28.95 sec (18.53 for Airtraq (P=0.32. The median IDS values were 4 (interquartile range (IQR 1-6 and 0 (IQR 0-1 for laryngoscopy and Airtraq, respectively (P=0.007. The median Cormack Lehane glottic view grade was 3 (IQR 2-4 and 1 (IQR 1-1 for laryngoscopy and Airtraq, respectively (P=0.003. The ease of intubation on VAS was graded as 4 (IQR 3-5 for laryngoscopy and 2 (IQR 2-2 for Airtraq (P=0.033. There were two failures to intubate with the Airtraq. Conclusion: Airtraq improves the ease of intubation significantly when compared to Mc Coy blade in patients immobilised with cervical collar and manual in-line stabilisation simulating cervical spine injury.

This study investigates the impact of isometric contraction of anterior cervical muscles on cervical lordosis. 29 volunteers were randomly assigned to an anterior head translation (n=15) or anterior head flexion (n=14) group. Resting neutral lateral cervical x-rays were compared to x-rays of sustained isometric contraction of the anterior cervical muscles producing anterior head translation or anterior head flexion. Paired sample t-tests indicate no significant difference between pre and post anterior head translation or anterior head flexion. Analysis of variance suggests that gender and peak force were not associated with change in cervical lordosis. Chamberlain's to atlas plane line angle difference was significantly associated with cervical lordosis difference during anterior head translation (p=0.01). This study shows no evidence that hypertonicity, as seen in muscle spasms, of the muscles responsible for anterior head translation and anterior head flexion have a significant impact on cervical lordosis.

However the incidence is still too high, especially among elderly women. All guidelines strongly recommend a regular Papanicolaou (Pap testing for young and middle-aged patients. On the other hand, many international professional societies no longer advise screening in women who have undergone hysterectomy, and in women aged 65 years and above, who have a previous history of regular Pap smears. Here we report the case of poorly differentiated CC, involving the pelvic lymph nodes and urinary bladder, occurring in a 79-year-old woman who regularly underwent Pap tests, with no reported cytological abnormalities. In this very rare case, the CC cells, as well as cells from metastatic lymph nodes and cells from urinary specimens, molecularly showed human papilloma virus (HPV-53. With the limitations of a single case, this report brings important information to prevent CC in elderly patients: the utility of molecular tests to increase sensitivity of Pap smears in postmenopausal women; the importance of HPV-53 as one of the four “emergent” genotypes having a possible role in oncogenesis; and the presence of HPV-53 in lymph node metastases from cervical carcinoma, which would support the role of this virus in the maintenance of malignant status.Keywords: old women, molecular tests, cervical cancer screening, HPV-DNA test, HPV genotypingA Letter to the editor has been received and published for this articleCorrigendum for this paper has been published

Predictors of persistent cytologic abnormalities after treatment of cervical intraepithelial neoplasia in Soweto, South Africa: a cohort study in a HIV high prevalence population

2008-07-01

Full Text Available Abstract Background In the presence of both HIV infection and cervical intraepithelial neoplasia (CIN, the risk of cancer development despite treatment may be greater. We investigated clinical predictors of persistent cytological abnormalities in women who had had a large loop excision of the transformation zone (LLETZ. Methods Women with high grade squamous intraepithelial lesions or worse (HSIL, less severe abnormalities which persisted and any abnormality in women who are HIV-infected, were referred to the colposcopy clinic. HIV infection was ascertained by self-report. A LLETZ was performed on all patients with HSIL or higher on Papanicolaou (Pap smear or colposcopy, LSIL or higher in patients who are HIV-infected, where the colposcopy is inadequate, and when there was a discrepancy between colposcopy and cytology by one or more grades. Women with abnormal follow-up smears were compared to those with normal smears. We examined the association between abnormal follow-up smears and demographic and clinical predictors using logistic regression Results The median time between LLETZ and first follow-up Pap smear was rather short at 122 days. Persistent cytological abnormalities occurred in 49% of our patients after LLETZ. Predictors of persistence included the presence of disease at both margins and HIV infection. Among the latter, disease at the excision margins and CD4+ cell count were important predictors. In these women, disease at the endocervical margin, both margins, and disease only at the ectocervical margin were associated with increased odds of persistent abnormalities on follow-up cervical smear. Conclusion We showed extremely high risk of cytological abnormality at follow-up after treatment more so in patients with incomplete excision and in the presence of immunocompromise. It remains uncertain whether recurrent CIN is a surrogate marker for invasive cervical cancer.

OBJECT The cervical interfacet spacer (CIS) is a relatively new technology that can increase foraminal height and area by facet distraction. These offer the potential to provide indirect neuroforaminal decompression while simultaneously enhancing fusion potential due to the relatively large osteoconductive surface area and compressive forces exerted on the grafts. These potential benefits, along with the relative ease of implantation during posterior cervical fusion procedures, make the CIS an attractive adjuvant in the management of cervical pathology. One concern with the use of interfacet spacers is the theoretical risk of inducing iatrogenic kyphosis. This work tests the hypothesis that interfacet spacers are associated with loss of cervical lordosis. METHODS Records from patients undergoing posterior cervical fusion at Rush University Medical Center between March 2011 and December 2012 were reviewed. The FacetLift CISs were used in all patients. Preoperative and postoperative radiographic data were reviewed and the Ishihara indices and cervical lordotic angles were measured and recorded. Statistical analyses were performed using STATA software. RESULTS A total of 64 patients were identified in whom 154 cervical levels were implanted with machined allograft interfacet spacers. Of these, 15 patients underwent anterior-posterior fusions, 4 underwent anterior-posterior-anterior fusions, and the remaining 45 patients underwent posterior-only fusions. In the 45 patients with posterior-only fusions, a total of 110 levels were treated with spacers. There were 14 patients (31%) with a single level treated, 16 patients (36%) with two levels treated, 5 patients (11%) with three levels treated, 5 patients (11%) with four levels treated, 1 patient (2%) with five levels treated, and 4 patients (9%) with six levels treated. Complete radiographic data were available in 38 of 45 patients (84%). On average, radiographic follow-up was obtained at 256.9 days (range 48-524 days

Cervical cancer being the cancer of cervix is caused by the aberrant cell growth that acquires an ability to spread/ invade to other body parts as well. It has been reported to be the second most commonest cause of death and cancer as well among women. Based on the severity of the disease, treatment aspect needs to be explored more in order to overcome the limitations acquired by conventional treatment. Recently, nanocarriers based drug delivery systems including liposomes, nanofibres, metallic NPs, polymeric NPs, dendrimers, polymeric micelles, antibody-drug conjugates etc. have been explored to target and treat cervical cancer. This review highlights numerous recent research and patent reports as well on nanocarriers based systems. Patents viz US, EP and WIPO have been retrieved using sites www.uspto.gov/patft and www.freepatentsonline.com to collect literature on nanocarriers. Various research reports and patents revealed nanocarriers to be effective in treating cervical cancer and these carriers are observed to be safer than the conventional treatment. Nanocarriers results in transforming drug distribution that can overpower drug resistance. Further, nanocarriers based drug delivery systems can particularly target drugs to cellular, subcellular and tissue sites. By enhancing the drug's bioavailability at the desired site, these systems result in therapeutic benefits like enhanced safety and efficacy. Also, in combination with other treatment approaches like radiation, photothermal and gene therapy, nanocarriers are reported to be quite effective and can define novel strategies to combat cervical cancer.

Full Text Available BACKGROUND Cancer of cervix is a global health problem and is a leading cause of morbidity and mortality of women in India. It is one of the most preventable and curable of all cancers. Simple, noninvasive screening procedures like Papanicolaou smears can help in detection and quick and effective timely treatment. The objective of the study is to assess the role of Pap smear in detecting premalignant, malignant and nonneoplastic lesions of cervix in our institute. MATERIALS AND METHODS This is a one year prospective and four year retrospective study of 1,349 women in age group of 20-80 years carried over a period of 5 years from January 2012-December 2016 in the cytology wing of Department of Pathology, Tripura Medical College. Patients clinically presenting with dyspareunia, postcoital bleeding, vaginal bleeding, frothy vaginal discharge with itching and pain in hypogastrium were included in the study. Samples were collected under direct vision of Cusco’s speculum and transferred to glass slides, fixed and stained by Papanicolaou stain and were examined and reported. Reporting was done as per Bethesda system. RESULTS A total of 1,349 number of cases were screened, out of which 639 number of patients had abnormal Pap smears and 13.63% had unsatisfactory or inadequate samples. LSIL was the most common premalignant lesion with 113 (8.37% number of cases, SCC in 39 (5.2% number of cases, ASCUS in 15 (1.11% and adenocarcinoma in 2 (0.14% number of cases. CONCLUSION It was found that premalignant and malignant lesion in cervix is not uncommon in our setup and Pap smear appears to be an elementary, economical, safe and yet highly sensitive screening test for early detection of various cervical lesions.

Women who delay or do not attend Papanicolaou (Pap) screening are at increased risk for cervical cancer. Trials in countries with organized screening programs have demonstrated that mailing high-risk (hr) human papillomavirus (HPV) self-sampling kits to under-screened women increases participation, but U.S. data are lacking. HOME is a pragmatic randomized controlled trial set within a U.S. integrated healthcare delivery system to compare two programmatic approaches for increasing cervical cancer screening uptake and effectiveness in under-screened women (≥3.4years since last Pap) aged 30-64years: 1) usual care (annual patient reminders and ad hoc outreach by clinics) and 2) usual care plus mailed hrHPV self-screening kits. Over 2.5years, eligible women were identified through electronic medical record (EMR) data and randomized 1:1 to the intervention or control arm. Women in the intervention arm were mailed kits with pre-paid envelopes to return samples to the central clinical laboratory for hrHPV testing. Results were documented in the EMR to notify women's primary care providers of appropriate follow-up. Primary outcomes are detection and treatment of cervical neoplasia. Secondary outcomes are cervical cancer screening uptake, abnormal screening results, and women's experiences and attitudes towards hrHPV self-sampling and follow-up of hrHPV-positive results (measured through surveys and interviews). The trial was designed to evaluate whether a programmatic strategy incorporating hrHPV self-sampling is effective in promoting adherence to the complete screening process (including follow-up of abnormal screening results and treatment). The objective of this report is to describe the rationale and design of this pragmatic trial. Copyright © 2017 Elsevier Inc. All rights reserved.

1985-01-01

Thirty patients underwent functional cervical myelography, i.e. radiographs in the lateral view were obtained in extension as well as in flexion of the neck. Sagittal tomography was performed in both positions. Narrowing of the subarachnoid space and increased sagittal diameter of the spinal cord due to shortening were demonstrated in the lateral view in extension. In flexion a widening of the subarachnoid space was seen in almost all. In some cases with advanced narrowing or spinal block in extension, such widening in flexion resulted in better diagnostic images by providing passage of the contrast medium caudally. Although iohexol (Omnipaque, Nyegaard and Co., Oslo) was regularly forced into the posterior cranial fossa by the movements, the frequency of side effects was approximately the same as in our former trials with iohexol in conventional cervical myelography. EEG changes occurred in two patients (7%). A sitting position for 3-4 min after the examination followed by an elevated head end of the bed was probably important for preventing side effects from the contrast medium. Specific questioning revealed twice as many subjective side effects as reported after general questions alone. (orig.)

The aim of the present study was to evaluate the reliability of the Cartesian Optoelectronic Dynamic Anthropometer (CODA) motion system in measuring the cervical range of motion (ROM) and verify the construct validity of the CODA motion system. A total of 26 patients with cervical spondylosis and 22 patients with anterior cervical fusion were enrolled and the CODA motion analysis system was used to measure the three-dimensional cervical ROM. Intra- and inter-rater reliability was assessed by interclass correlation coefficients (ICCs), standard error of measurement (SEm), Limits of Agreements (LOA) and minimal detectable change (MDC). Independent samples t-tests were performed to examine the differences of cervical ROM between cervical spondylosis and anterior cervical fusion patients. The results revealed that in the cervical spondylosis group, the reliability was almost perfect (intra-rater reliability: ICC, 0.87-0.95; LOA, -12.86-13.70; SEm, 2.97-4.58; inter-rater reliability: ICC, 0.84-0.95; LOA, -13.09-13.48; SEm, 3.13-4.32). In the anterior cervical fusion group, the reliability was high (intra-rater reliability: ICC, 0.88-0.97; LOA, -10.65-11.08; SEm, 2.10-3.77; inter-rater reliability: ICC, 0.86-0.96; LOA, -10.91-13.66; SEm, 2.20-4.45). The cervical ROM in the cervical spondylosis group was significantly higher than that in the anterior cervical fusion group in all directions except for left rotation. In conclusion, the CODA motion analysis system is highly reliable in measuring cervical ROM and the construct validity was verified, as the system was sufficiently sensitive to distinguish between the cervical spondylosis and anterior cervical fusion groups based on their ROM.

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.

To compare the radiation dosage and costs in conventional and digital technologies. The study dealt with transverse sections. The dosage applied with conventional technology was measured in 254 patients who intertwined 402 explorations of 6 anatomic regions in 4 Radiodiagnostic Services. The dosage applied with digital technology was measured in 57 patients who underwent 95 explorations of the same anatomic region in one Radiodiagnostic Service. The costs of the 6 types of conventional and digital explorations performed were calculated for two Radiodiagnostic Service. The doses administered (mGy) using convectional/digital technology were as follows: chest PA 0.2/0.1; chest LAT 0.7/0.3; breast CC 7.0/8.4; breast LAT 7.0/7.8; breast OB 7.0/10.5; cervical spine AP 9.6/9.0; cervical spine LAT 21.9/29.6; pelvis AP 7.3/7.1; plain abdominal 6.5/2.2. The costs incurred (1992 pesetas) with the convectional/digital technologies: chest AP and LAT 1,393/2,973; portable chest 2,027/3,714; mammography 2,357/3,486; phlebography 12,718/14,023; hysterosalpingography 4,876/6,701; bone scientigraphy 1,633/2,839. Compared with conventional technology, digital imaging reduces the radiation doses received by the patients, except in the case of mammography. The costs associated with the use of digital technology are greater than those incurred with conventional technology, mainly due to the costs of amortization. the use of digital technology is more justified when: 1) it is very necessary to reduce the dosage; 2) studies of chest and abdomen predominant; 3) the volume of utilization is high; 4) staff management is flexible , and 5) the cost of purchasing the equipment is lower.

Cervical-cancer screening strategies that involve the use of conventional cytology and require multiple visits have been impractical in developing countries. We used computer-based models to assess the cost-effectiveness of a variety of cervical-cancer screening strategies in India, Kenya, Peru, South Africa, and Thailand. Primary data were combined with data from the literature to estimate age-specific incidence and mortality rates for cancer and the effectiveness of screening for and treatment of precancerous lesions. We assessed the direct medical, time, and program-related costs of strategies that differed according to screening test, targeted age and frequency, and number of clinic visits required. Single-visit strategies involved the assumption that screening and treatment could be provided in the same day. Outcomes included the lifetime risk of cancer, years of life saved, lifetime costs, and cost-effectiveness ratios (cost per year of life saved). The most cost-effective strategies were those that required the fewest visits, resulting in improved follow-up testing and treatment. Screening women once in their lifetime, at the age of 35 years, with a one-visit or two-visit screening strategy involving visual inspection of the cervix with acetic acid or DNA testing for human papillomavirus (HPV) in cervical cell samples, reduced the lifetime risk of cancer by approximately 25 to 36 percent, and cost less than 500 dollars per year of life saved. Relative cancer risk declined by an additional 40 percent with two screenings (at 35 and 40 years of age), resulting in a cost per year of life saved that was less than each country's per capita gross domestic product--a very cost-effective result, according to the Commission on Macroeconomics and Health. Cervical-cancer screening strategies incorporating visual inspection of the cervix with acetic acid or DNA testing for HPV in one or two clinical visits are cost-effective alternatives to conventional three

Methods/materials: We conducted a cross-sectional pilot study in rural Uganda. We explored associations between women's characteristics and acceptance of VIA testing. We collected samples for Papanicolaou (Pap smear testing in a random subset of women and used results from this test as a comparator for assessing VIA performance. Results: We enrolled 625 women of whom 571 (91.4% accepted and 54 (8.6% refused CC screening. In the univariate model, age (Odds Ratio (OR=1.10; p-value<0.001 and employment status (OR 2.00; p-value=0.019 were significantly associated with acceptance of VIA screening. In the multivariate model, no characteristic was independently associated with acceptance of VIA screening after adjusting for other factors. Compared to reference Pap smear, CC screening with VIA had a sensitivity of 50% and a specificity of 97.7%. Conclusions: CC screening with VIA is highly acceptable in the setting of rural immunization clinics in Uganda. Studies to assess which screening method would be the most effective and cost-effective are needed before stakeholders can consider adopting screening programs at scale.

Cervical cancer screening is one of the most effective cancer prevention strategies, but most women in Africa have never been screened. In 2007, the Cameroon Baptist Convention Health Services, a large faith-based health care system in Cameroon, initiated the Women's Health Program (WHP) to address this disparity. The WHP provides fee-for-service cervical cancer screening using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC), prioritizing care for women living with HIV/AIDS. They also provide clinical breast examination, family planning (FP) services, and treatment for reproductive tract infection (RTI). Here, we document the strengths and challenges of the WHP screening program and the unique aspects of the WHP model, including a fee-for-service payment system and the provision of other women's health services. We retrospectively reviewed WHP medical records from women who presented for cervical cancer screening from 2007-2014. In 8 years, WHP nurses screened 44,979 women for cervical cancer. The number of women screened increased nearly every year. The WHP is sustained primarily on fees-for-service, with external funding totaling about $20,000 annually. In 2014, of 12,191 women screened for cervical cancer, 99% received clinical breast exams, 19% received FP services, and 4.7% received treatment for RTIs. We document successes, challenges, solutions implemented, and recommendations for optimizing this screening model. The WHP's experience using a fee-for-service model for cervical cancer screening demonstrates that in Cameroon VIA-DC is acceptable, feasible, and scalable and can be nearly self-sustaining. Integrating other women's health services enabled women to address additional health care needs. The Cameroon Baptist Convention Health Services Women's Health Program successfully implemented a nurse-led, fee-for-service cervical cancer screening program using visual inspection with acetic acid-enhanced by digital cervicography in

2002-01-01

The cervical spine is a common focus of destruction from rheumatoid arthritis, second only to the metacarpophalangeal joints. Joint, bone and ligament damage in the cervical spine leads to subluxations which can cause cervical cord compression resulting in paralysis and even sudden death. Because many patients with significant subluxations are asymptomatic, the radiologist plays a key role in recognizing the clinically important clues to instability on plain radiographs of the cervical spine-often difficult in rheumatoid arthritis when the bony landmarks are osteoporotic or eroded. This review focuses on the signs of instability on plain radiographs of the cervical spine, using diagrams and clinical examples to illustrate methods of identifying significant subluxations in rheumatoid arthritis.

Marcel Machado da Motta

Full Text Available ABSTRACT Objective: To correlate the radiographic parameters of sagittal cervical alignment with quality of life and functional capacity in patients with cervical spondylosis under conservative treatment. Methods: This is an observational and prospective study in patients with cervical spondylosis under conservative treatment and without indication for surgery. The 52 patients included were divided into three groups: axial pain, radiculopathy, and cervical myelopathy. The radiographic parameters considered were cervical lordosis (CL, cervical sagittal vertical axis (CSVA, T1 slope (TS and the discrepancy between TS and CL (TS-CL. Quality of life and functional capacity were evaluated by the Neck Disability Index (NDI questionnaire. Pain was assessed by the Visual Analogue Scale (VAS. The correlation between the radiographic parameters and the clinical scores was evaluated by the Pearson correlations coefficient. Results: There was no difference in cervical radiographic parameters between the three groups. In the total of the sample, the mean value of the CSVA was 17.8o (±8.3o, CL, 22.4° (± 8.8°; TS, 29.3° (±6.6°, and TS-CL, 7.0° (±7.4°. Significant inverse correlation (r= -0.3, p=0.039 was observed between NDI and CL, but there was no significant correlation between CL and VAS. CSVA (p=0.541, TS (p=0.287 and TS-CL (p=0.287 had no significantly correlated with NDI or VAS. Conclusion: Considering patients with cervical spondylosis not candidates for surgery, the only sagittal parameter that correlated with functional capacity was LC. In these patients, the correlation between cervical alignment and quality of life needs to be better characterized.

Full Text Available Introduction: Cervical cancer is one of the most common causes of death in women worldwide. [1] The introduction of cervical cytology in screening programs is an effective way for early detection and treatment of cervical precancerous lesions. Conventional screening of cervical cytology slides is still considered the current "gold standard" for the assessment of proficiency in becoming a cytotechnician, but diagnosis using digital whole slide images (WSI may offer many advantages. Materials and Methods: In this study, we have used a selection of WSI from thin-layer specimens of the most common cervical infections and (pre neoplastic lesions, and hypothesized that weekly WSI based case-meetings would help to obtain optimal acceptance of the new digital workflow in daily pathology practice. A questionnaire, before and after the test period was used to study the effect of our approach. Results: The participants clearly had to go through a learning curve to get accustomed to viewing WSI. In the beginning, there was a little self-confidence in recognizing classical cervical cytomorphological features in the WSI, and there were complaints about the speed of viewing and insufficient Z-resolution for cell groups. Adjusting the Z-stack settings resulted in better three-dimensional information due to better focusing options. Weekly meetings appeared to be instrumental in the implementation process, as participants had to select and present WSI from thematic cases themselves, and thereby, got used to viewing WSI. Some WSI were replaced by better ones until a final set of 45 representatives WSI remained. Eventually, the consensus was reached among all participants that cytomorphological features in WSI from thin-layers cervical specimens could comparably be appreciated in WSI as by conventional microscopy. The selection of 45 WSI was now used to create a digital WSI based reference atlas to support further studies. Conclusion: We have obtained consensus

Full Text Available OBJECTIVE: To assess cost-effectiveness of conventional cytology and HPV DNA testing for cervical-cancer screening in Colombia. MATERIAL AND METHODS: The National Cancer Institute of Colombia (NCIC in 2007 developed a Markov model on the natural history of cervical cancer; no screening, conventional cytology, and HPV DNA testing were compared. Only direct costs were used. Outcomes comprise cervical cancer mortality, years of life saved, and lifetime costs. Discounted incremental cost-effectiveness ratios were estimated and sensitivity analyses were conducted for key parameters. RESULTS: Depending on the screening strategy a 69-81% mortality reduction might be expected. The HPV DNA testing every five years is a cost-effective strategy (Incremental Cost-Effectiveness Ratio (ICER: USD$44/YLS if the cost per test is under USD$31. The effectiveness was sensitive to coverage and primarily to follow-up. CONCLUSIONS: HPV DNA testing is a cost-effective alternative for screening in Colombia. Not only high coverage but high follow-up rates are critical for successful screening programs.OBJETIVO: evaluar el costo-efectividad de la citología convencional y la prueba de ADN-VPH para tamización de cáncer cervical en Colombia.

Objective: This presentation's goal is to define the indications of the procedure, to describe a new way to access to the foramen, and to evaluate the results. Material and method: Between November 2000 and October 2004, we performed 12 blockades of cervical nerves roots in 11 patients (5 female and 6 males, aged from 37 to 62 years old) with cervical pain without resolution under conventional treatment. The cause of the symptoms included: 7 patients with cervical disc protrusion and 4 patients with cervical degenerative processes diagnosed by previous Magnetic Resonance Imaging (MRI) studies. The levels of the procedure were: 1 in C3, on the right side (8.3%); 2 in C5, on the left side (16.6%); 6 in C6 (5 on the right side and 1 on the left), (50%); and 3 in C7 (25%), under CT guidance alone, with a posterior-lateral access. Results: The first clinical control after 1 hour showed a complete pain remission in all the 11 patients (100%). The second control (15 days after) showed 9 patients (81.9%) without pain, one patient (9,1%) with partial pain relief without medication, and one patient (9,1%) with pain relapse. Finally, in the third control (3 months later) based on ten patients (one of them was not yet on the period of the third control), 7 of them (70%), continued without pain, one patient (10%) showed a partial resolution of the pain without medication, one patient (10%) presented a partial resolution with medication, and one patient (10%), continued with pain and was treated surgically. There was no complication of the procedure in our patients. Conclusion: The cervical nerves root blockade with steroids and anesthetic under CT guidance, with posterolateral access is a safe, minimally invasive procedure, with no complications, that provides a quick solution to the cervical pain. Therefore, this procedure must be considered as a preliminary step before other aggressive treatments such as surgical therapy in a medical decision context. (author)

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)

While (Pap)anicolaou screening has helped to decrease cervical cancer incidence in Canada, First Nations women continue to have a higher burden and mortality relative to mainstream populations. Many First Nations women may feel uncomfortable with the invasiveness of this test, contributing to this statistic. Implemented from 2009 to 2015 in 10 Northwest Ontario First Nations communities, the Anishinaabek Cervical Cancer Screening Study (ACCSS) uniquely addressed this Indigenous health inequity through a mixed methods approach. Our goal was to offer an alternative test which the women could do themselves: human papillomavirus (HPV) testing based on self-sampling. We investigated whether First Nations women preferred HPV self-sampling over healthcare provider (HCP)-administered Pap screening. Participatory action researchinformed by the ethical space concept has guided all stages of the ACCSS. We conducted qualitative interviews with 16 HCPs and 8 focus group discussions with 69 female community members followed by a cluster-randomised controlled trial (RCT). Here, we draw on the qualitative field data and an end-of-study community update gathering to disseminate and contextualise research findings. Informant data were evaluated using thematic analysis. We discuss factors influencing participants' strong preference for HPV self-sampling over physician-conducted Pap screening. Key arguments included enhanced accessibility and more personal control, less physical and emotional discomfort and fewer concerns regarding privacy of test results. For future implementation of HPV self-sampling, study participants emphasised the need for more culturally sensitive education addressed to community members of all genders, starting at school, clarifying that HPV causes cervical cancer. Further, HPV infection should be de-stigmatised by accentuating that it affects men and women alike. Here we show that self-sampling in conjunction with community engagement and culturally sensitive

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

Pathophysiology of cervical myelopathy.

Baptiste, Darryl C; Fehlings, Michael G

2006-01-01

Cervical myelopathy is a group of closely related disorders usually caused by spondylosis or by ossification of the posterior longitudinal ligament and is characterized by compression of the cervical spinal cord or nerve roots by varying degrees and number of levels. The decrease in diameter of the vertebral canal secondary to disc degeneration and osteophytic spurs compresses the spinal cord and nerve roots at one or several levels, producing direct damage and often secondary ischemic changes. Clinicians who treat cervical myelopathy cord injuries should have a basic understanding of the pathophysiology and the processes that are initiated after the spinal cord has been injured. Literature review. Literature review of human cervical myelopathy and clinically relevant animal models to further our understanding of the pathological mechanisms involved. The pathophysiology of cervical myelopathy involves static factors, which result in acquired or developmental stenosis of the cervical canal and dynamic factors, which involve repetitive injury to the cervical cord. These mechanical factors in turn result in direct injury to neurons and glia as well as a secondary cascade of events including ischemia, excitotoxicity, and apoptosis; a pathobiology similar to that occurring in traumatic spinal cord injury. This review summarizes some of the significant pathophysiological processes involved in cervical myelopathy.

Context: Prior studies have shown common use of post-operative bracing, despite advances in modern day instrumentation rigidity and little evidence of brace effectiveness. To document current practice patterns of brace use after degenerative cervical spine surgeries among members of the Cervical Spine Research Society (CSRS), to evaluate trends, and to identify areas of further study. A questionnaire survey METHODS: A 10 question survey was sent to members of the Cervical Spine Research Society to document current routine bracing practices after various common degenerative cervical spine surgical scenarios, including fusion and non-fusion procedures. The overall bracing rate was 67%. This included 8.4% who used a hard collar in each scenario. Twenty-two percent of surgeons never used a hard collar, while 34% never used a soft collar, and 3.6% (3 respondents) did not use a brace in any surgical scenario. Bracing frequency for specific surgical scenarios varied from 39% after foraminotomy to 88% after multi-level corpectomy with anterior & posterior fixation. After one, two and three level anterior cervical discectomy & fusion (ACDF), bracing rates were 58%, 65% and 76% for an average of 3.3, 4.3 and 5.3 weeks, respectively. After single level corpectomy, 77% braced for an average of 6.2 weeks. After laminectomy and fusion, 72% braced for an average of 5.4 weeks. Significant variation persists among surgeons on the type and length of post-operative brace usage after cervical spine surgeries. Overall rates of bracing have not changed significantly with time. Given the lack evidence in the literature to support bracing, reconsidering use of a brace after certain surgeries may be warranted. Copyright © 2018. Published by Elsevier Inc.

Full Text Available OBJECTIVE: To assess the impact of health care access and socioeconomic determinants on Pap smear screening in Latin America. METHODS: Individual-level data was collected from the Demographic and Health Surveys in Bolivia, Brazil, Dominican Republic, Ecuador, Guatemala, Nicaragua, Peru, and Trinidad and Tobago between 1987 and 2008. Multivariate logistic regression analyses were used to identify socioeconomic and health care determinants of two outcomes: knowledge of Pap smears and recent Pap smear screening. RESULTS: In all countries, the proportion of women with a recent Pap smear screening remained below 55%. Key determinants of knowledge of Pap smears were age, education, and recent doctor's visit. For recent Pap smear screening, key determinants were wealth and recent doctor's visit. Women were between 1.47 and 3.44 times more likely to have received a recent Pap smear if they had a recent doctor's visit. Even the poorest women with a recent doctor's visit were more likely to screen than the richest women without a recent visit. CONCLUSIONS: These data suggest that visiting a doctor is an important determinant of cervical cancer screening in Latin America. Because screening may coincide with other medical visits, physicians could effectively encourage screening.OBJETIVO: Evaluar las repercusiones del acceso a la atención de salud y de los determinantes socioeconómicos sobre la detección sistemática del cáncer cervicouterino con la prueba de Papanicolaou en América Latina.

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.

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

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.

Chronic neck pain: making the connection between capsular ligament laxity and cervical instability.

Science.gov (United States)

Steilen, Danielle; Hauser, Ross; Woldin, Barbara; Sawyer, Sarah

2014-01-01

The use of conventional modalities for chronic neck pain remains debatable, primarily because most treatments have had limited success. We conducted a review of the literature published up to December 2013 on the diagnostic and treatment modalities of disorders related to chronic neck pain and concluded that, despite providing temporary relief of symptoms, these treatments do not address the specific problems of healing and are not likely to offer long-term cures. The objectives of this narrative review are to provide an overview of chronic neck pain as it relates to cervical instability, to describe the anatomical features of the cervical spine and the impact of capsular ligament laxity, to discuss the disorders causing chronic neck pain and their current treatments, and lastly, to present prolotherapy as a viable treatment option that heals injured ligaments, restores stability to the spine, and resolves chronic neck pain. The capsular ligaments are the main stabilizing structures of the facet joints in the cervical spine and have been implicated as a major source of chronic neck pain. Chronic neck pain often reflects a state of instability in the cervical spine and is a symptom common to a number of conditions described herein, including disc herniation, cervical spondylosis, whiplash injury and whiplash associated disorder, postconcussion syndrome, vertebrobasilar insufficiency, and Barré-Liéou syndrome. When the capsular ligaments are injured, they become elongated and exhibit laxity, which causes excessive movement of the cervical vertebrae. In the upper cervical spine (C0-C2), this can cause a number of other symptoms including, but not limited to, nerve irritation and vertebrobasilar insufficiency with associated vertigo, tinnitus, dizziness, facial pain, arm pain, and migraine headaches. In the lower cervical spine (C3-C7), this can cause muscle spasms, crepitation, and/or paresthesia in addition to chronic neck pain. In either case, the presence of

We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance (ρ > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury

They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance ({rho} > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury.

Objectives. Digital impressions are increasingly used and have the potential to avoid the problem of inaccurate impressions. Only a few studies to verify the accuracy of digital impressions have been performed. The purpose of this study was to compare the marginal and internal fit of 3-unit tooth supported fixed dental prostheses (FDPs) fabricated from digital and conventional impressions. Methods. Ten FDPs were produced from digital impressions using the iTero system and 10 FDPs were produced using vinyl polysiloxane (VPS) impression material. A triple-scan protocol and CAD software were used for measuring and calculating discrepancies of the FDPs at 3 standard areas: mean internal discrepancy, absolute marginal gap, and cervical area discrepancy. The Mann-Whitney U test was used for analyzing the results. Results. For conventional and digital impressions, respectively, FDPs had an absolute marginal gap of 147  μ m and 142  μ m, cervical area discrepancy of 69  μ m and 44  μ m, and mean internal discrepancy of 117  μ m and 93  μ m. The differences were statistically significant in the cervical and internal areas (P digital impression technique is more exact and can generate 3-unit FDPs with a significantly closer fit compared to the VPS technique.

Cervical cancer mortality is high along the US–Mexico border. We describe the prevalence of a recent Papanicolaou screening test (Pap) among US and Mexican border women. We analyzed 2006 cross-sectional data from Mexico’s National Survey of Health and Nutrition and the US Behavioral Risk Factor Surveillance System. Women aged 20–77 years in 44 US border counties (n = 1,724) and 80 Mexican border municipios (n = 1,454) were studied. We computed weighted proportions for a Pap within the past year by age, education, employment, marital status, health insurance, health status, risk behaviors, and ethnicity and adjusted prevalence ratios (APR) for the US, Mexico, and the region overall. Sixty-five percent (95 %CI 60.3–68.6) of US women and 32 % (95 %CI 28.7–35.2) of Mexican women had a recent Pap. US residence (APR = 2.01, 95 %CI 1.74–2.33), marriage (APR = 1.31, 95 %CI 1.17–1.47) and insurance (APR = 1.38, 95 %CI 1.22–1.56) were positively associated with a Pap test. Among US women, insurance and marriage were associated (APR = 1.21, 95 %CI 1.05–1.38 and 1.33, 95 %CI 1.10–1.61, respectively), and women aged 20–34 years were about 25 % more likely to have received a test than older women. Insurance and marriage were also positively associated with Pap testing among Mexican women (APR = 1.39, 95 %CI 1.17–1.64 and 1.50; 95 %CI 1.23–1.82, respectively), as were lower levels of education (≤8th grade or 9th–12th grade versus some college) (APR = 1.74; 95 %CI 1.21–2.52 and 1.60; 95 %CI 1.03–2.49, respectively). Marriage and insurance were associated with a recent Pap test on both sides of the border. Binational insurance coverage increases and/or cost reductions might bolster testing among unmarried and uninsured women, leading to earlier cervical cancer diagnosis and potentially lower mortality.

To investigate the effect of artesunate on radio-sensitivity of human cervical cancer cells in vitro. The human cervical cancer cells HeLa and Siha were used as the experimental cells. MTT assay was used to determine the most appropriate drug concentration in the subsequent experiment, and the effect of human cervical cancer cells treated with artesunate and irradiation of 60 Co γ-rays was studied by using conventional chromosomal aberration analysis and cytokinesis block method (CB method). The results show that when the concentration of artesunate in this experiment was 2.0 μmol/L for HeLa cell and 4.0 μmol/L for Siha cell respectively, the chromosome aberration, micronuclei cell and micronuclei rates of HeLa cells treated with artesunate were more serious than that of the only irradiation, but there is almost no change with Siha cells.

Inverse association between methylation of human papillomavirus type 16 DNA and risk of cervical intraepithelial neoplasia grades 2 or 3.

Directory of Open Access Journals (Sweden)

Long Fu Xi

Full Text Available The clinical relevance of human papillomavirus type 16 (HPV16 DNA methylation has not been well documented, although its role in modulation of viral transcription is recognized.Study subjects were 211 women attending Planned Parenthood clinics in Western Washington for routine Papanicolaou screening who were HPV16 positive at the screening and/or subsequent colposcopy visit. Methylation of 11 CpG dinucleotides in the 3' end of the long control region of the HPV16 genome was examined by sequencing the cloned polymerase chain reaction products. The association between risk of CIN2/3 and degree of CpG methylation was estimated using a logistic regression model.CIN2/3 was histologically confirmed in 94 (44.5% of 211 HPV16 positive women. The likelihood of being diagnosed as CIN2/3 increased significantly with decreasing numbers of methylated CpGs (meCpGs in the 3' end of the long control region (P(for trend = 0.003. After adjusting for HPV16 variants, number of HPV16-positive visits, current smoking status and lifetime number of male sex partners, the odds ratio for the association of CIN2/3 with ≥4 meCpGs was 0.31 (95% confidence interval, 0.12-0.79. The proportion of ≥4 meCpGs decreased appreciably as the severity of the cervical lesion increased (P(for trend = 0.001. The inverse association remained similar when CIN3 was used as the clinical endpoint. Although not statistically significant, the ≥4 meCpGs-related risk reduction was more substantial among current, as compared to noncurrent, smokers.Results suggest that degree of the viral genome methylation is related to the outcome of an HPV16 cervical infection.

The objective of this study was to examine the association between inadequate functional health literacy in Spanish among low-income Latinas aged 40 and older and cervical cancer screening knowledge and behavior. Spanish-speaking Latinas aged 40-78 of various nationalities (n = 205) participated in a study that included a survey on cervical cancer knowledge and behavior administered in Spanish and the Spanish version of the Test of Functional Health Literacy in Adults. Compared to those with adequate and marginal health literacy, women with inadequate functional health literacy in Spanish were significantly less likely to have ever had a Papanicolaou (Pap) test (odds ratio, 0.12; 95% confidence interval [CI], 0.04-0.37) or in the last three years (odds ratio, 0.35; 95% CI, 0.18-0.68) and were significantly more likely to have had their last Pap test at a local public hospital (odds ratio, 2.43; 95% CI, 1.18-4.97). Even when controlling for other factors, women with inadequate health literacy were 16.7 times less likely (adjusted odds ratio, 0.06; 95% CI, 0.01-0.55) to have ever had a Pap test. Almost half of the population we studied will have difficulty interpreting written medical materials, even in Spanish. When developing efforts to reach women who have not been screened, programs and service providers need to be aware that the women most in need of information about screening may be more likely to be unable to read any written materials provided to them, regardless of the language or level of simplicity of the materials. Programs and strategies need to be implemented to increase screening prevalence and to minimize the identified gaps in regular screening for Latinas who have low health literacy.

Participation in Human Papillomavirus (HPV) vaccination and Papanicolaou Screening (Pap smears) is low among ethnic minorities in the Netherlands and hardly any information is available about the cervical cancer prevention methods of Somali women living in the diaspora. This qualitative study, based on the Health Belief Model (HBM) and an intersectionality-based framework, explores the perceptions of Somali women living in the Netherlands regarding measures to prevent cervical cancer. Semi-structured interviews have been conducted with young Somali women aged 17-21 years (n = 14) and Somali mothers aged 30-46 years (n = 6). Two natural group discussions have been conducted with 12 and 14 Somali mothers aged 23-66 years. The collected data has been analyzed thematically for content. In this study, we have identified perceived barriers to the use of preventive measures across three major themes: (1) Somali women and preventive healthcare; (2) Language, knowledge, and negotiating decisions; and (3) Sexual standards, culture, and religion. Many issues have been identified across these themes, e.g., distrust of the Dutch health care system or being embarrassed to get Pap smears due to Female Genital Mutilation (FGM) and having a Dutch, male practitioner; or a perceived low susceptibility to HPV and cancer because of the religious norms that prohibit sex before marriage. Current measures in the Netherlands to prevent women from developing cervical cancer hardly reach Somali women because these women perceive these kinds of preventative measures as not personally relevant. Dutch education strategies about cervical cancer deviate from ways of exchanging information within the Somali community. Teachers can provide culturally sensitive information to young Somali women in schools. For Somali mothers, oral education (e.g., poetry or theater) about the Dutch health care system and men's roles in HPV transmission may be useful. An intersectional approach, grounded in

Usefulness of 18FDG PET in the management of cervical cancer

2002-01-01

Cervical carcinoma is the second most common gynaecological cancer worldwide. Despite substantial advances in screening the pre-invasive forms, the management of women suffering from invasive cervical carcinomas remains problematic. In pre-treatment staging, the evaluation of the loco-regional and distant extent of the disease, according to the international federation of gynecology and obstetrics, has shown to be sub-optimal. After treatment, the routine surveillance protocol, based on a physical examination at the control visits and clinically oriented conventional imaging procedures, most often fails to accurately detect a recurrent disease. Its sensitivity is particularly low for asymptomatic women. On the other hand, the clinical value of positron emission tomography using 18 F-fluorodeoxyglucose in the field of oncology is nowadays firmly established. In many tumour types, including the gynaecological cancers such as breast cancer and ovarian cancer, the metabolic imaging has proved to play a determinant role in both the pre-treatment and post-treatment evaluation. In the present review-article, we analyse in the light of the literature data and our experience, the potential contribution of positron emission tomography using 18 F-fluorodeoxyglucose in the management of cervical cancer.

Full Text Available Abstract Introduction Cervical necrotizing fasciitis is an aggressive infection with high morbidity and mortality. We present a case of cervical necrotizing fasciitis and descending mediastinitis in a healthy young man, caused by unilateral tonsillitis with a successful outcome without aggressive debridement. Case presentation A 41-year-old man was admitted to our unit with a diagnosis of severe acute unilateral tonsillitis. On admission, he had painful neck movements and the skin over his neck was red, hot and tender. Computed tomography scan of his neck and chest showed evidence of cervical necrotizing fasciitis and descending mediastinitis secondary to underlying pharyngeal disease. He was treated with broad-spectrum intravenous antibiotics. His condition improved over the next 3 days but a tender and fluctuant swelling appeared in the suprasternal region. A repeat scan showed the appearance of an abscess extending from the pretracheal region to the upper mediastinum which was drained through a small transverse anterior neck incision. After surgery, the patient's condition quickly improved and he was discharged on the 18th day of admission. Conclusion Less invasive surgical techniques may replace conventional aggressive debridement as the treatment of choice for cervical necrotizing fasciitis and descending necrotizing mediastinitis.

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

EPIDERMAL GROWTH FACTOR RECEPTOR (EGFR AND HUMAN PAPILLOMAVIRUS (HPV L1 CAPSID PROTEIN IN CERVICAL SQUAMOUS INTRAEPITHELIAL LESIONS

Directory of Open Access Journals (Sweden)

Balan Raluca

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

The aim of this study was to estimate the effect of cervical screening in the prevention of invasive cervical cancer among age groups, using a population-based case-control study in the province of Ontario, Canada. Exposure was defined as cervical cytology history greater than 3 months before the diagnosis date of cervical cancer (index date). Cases were women who were diagnosed with cervical cancer between January 1, 1998, and December 31, 2008. Controls were women without a diagnosis of cervical cancer on, or before, December 31, 2008. Two controls were matched to each case on year of birth and income quintile, as of the index date. Conditional logistic regression was used to estimate the odds ratio for having been screened among those with cervical cancer. Cervical cancer screening performed between 3 and 36 months before the index date was protective against invasive cervical cancer in women aged 40 through 69 years. In women younger than 40 years, cervical cancer screening performed 3 to 36 months before the index date was not protective. Cervical screening is associated with a reduced risk for invasive cervical cancer among women older than 40 years. Cervical cancer resources should be focused on maximizing the risk reduction.

Intraoperative irradiation in advanced cervical cancer

Conventional treatment of cervical cancer, such as radical hysterectomy with lymphadenectomy or pelvic exenteration, is limited to the pelvis. Standard radio-therapeutic treatment is a combination of external-beam radiotherapy to the pelvis and intracavitary applications. However, there is a group of patients for whom external radiotherapy alone has limitations. This group consists primarily of patients with large pelvic lymph nodes containing metastatic cancer, metastatically involved paraaortic lymph nodes outside the usual pelvic radiation field, or large central tumors with parametrial involvement. In patients with cancer of the cervix, the incidence of metastasis to paraaortic lymph nodes is high. Attempts to treat paraaortic nodes with external radiotherapy have resulted in high complication rates because the treatment field includes the highly sensitive gastrointestinal tract. External radiation therapy after retroperitoneal exploration of lymph nodes does not seem to improve survival. In an attempt to circumvent the morbidity and mortality associated with conventional external-beam irradiation, the authors initiated a pilot study of intraoperative electron-beam irradiation of the paraaortic nodes and of the large metastatic lymph nodes in the pelvis. The intraoperative boost was followed by conventional fractionated external-beam irradiation. The theoretical advantages of this procedure include a higher radiation tumor dose without a concomitant increase in treatment morbidity and mortality

Objective: To evaluate the safety and effectiveness of CT-guided cervical interlaminar epidural steroid injection for the treatment of cervical radiculopathy. Methods: CT-guided cervical interlaminar epidural steroid injection was performed in 32 patients with cervical radioculopathy, encountered during the period of Dec. 2006 to June 2008, as the patients failed to respond to the conservative treatment in 2 weeks. The clinical data and the imaging findings were retrospectively analyzed. Before and after the procedure, visual analogue scale (VAS) and Odom criteria were used to evaluate the pain of the patient. Results: Three months after the injection, improvement judged by Odom criteria was seen in 28 patients (87.5%), and the mean pain relief value of VAS was 5.88 ± 1.10. No significant difference in effective rate and in VAS score (P>0.05) was found between protrusion group and degenerative group, between the group with the course over 6 months and the group with the course below 6 months, also between the group receiving one injection and the group receiving the second injection. Conclusion: CT-guided fine needle (23 gauge) puncture epidural steroid (Decadron) 'target spot' injection is an ideal alternative for the treatment of cervical radiculopathy, especially for the patients who fails to respond to the conservative treatment.

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

Playing the violin can lead to asymmetric postures which can affect the cervical range of motion, cervical core strength and scapular stability. The objective of the study was to assess the cervical range of motion, cervical core strength and scapular dyskinesia in violin players and non-players of the same age group. An inclinometer was used to assess the cervical range of motion, pressure biofeedback was used to assess cervical core strength and scapular dyskinesia was also assessed in 30 professional violin players (18-40 years) compared with 30 age-matched non-players. Analysis was done using an unpaired t test. Significant change was seen with respect to extension (p = 0.051), cervical core strength (p = 0.005), right (Rt) superior angle 0° (p = 0.004), Rt superior angle 45° (p = 0.015) and Rt inferior angle 90° (p = 0.013). This study shows a significant difference in extension range of motion and cervical core strength of violin players. Also, there was scapular dyskinesia seen at 0° and 45° right-side superior angle of the scapula and 90° right-side inferior angle of the scapula.

Cervical cancer is the predominant cancer among women in Kenya and second most common in women in developing regions. Population-based cytological screening and early treatment reduces morbidity and mortality associated with the cancer. We determined the occurrence of cervical precancerous changes and cervical microbial infections (Trichomonas vaginalis, Candida albicans, Neisseria gonorrhea and Actinomyces) among women attending Family Health Option Kenya (FHOK) clinic in Thika. This was a hospital based cross sectional study among women attending reproductive health screening clinic from November 2013 to January 2014. Cervical Intraepithelial Neoplasia (CIN) I, II, III, cervical cancer and microbial infection (Actinomyces, Trichomonas vaginalis and Yeast cells) diagnosis was based on Pap smear screening test and High Vaginal Swab wet preparation microscopy. Neisseria gonorrhea was diagnosed through Gram staining. Socio-demographic and reproductive health data was collected using a structured questionnaire administered to the study participants and analyzed using Epi Info version 3.5.1. Of the 244 women screened, 238 (97.5%) presented with cervical inflammation, 80 (32.8%) cervical microbial infections and 12 (4.9%) cervical precancerous changes; 10 (83.3%) with CIN I and 2 (16.7%) CIN II. Of the 80 cervical microbial infections, 62 (77.5%) were yeast cell and 18 (22.5%) T. vaginalis. One thirty four (55%) participants had no history of Pap smear screening of which 84 (62.7%) were 20-40 years. Use of IUCDs (OR: 2.47, 95% CI 1.3-4.6) was associated with cervical inflammation. CIN I was the predominant cervical precancerous change. There is need to scale up cervical screening test to capture all categories of women.

Multidetector-row computed tomography (MRCT) has advantages in comparison to conventional helical computed tomography, such as reduction of study time, lower radiation doses, fewer metallic artifacts and high quality multiplanar reformatting and three dimensional reconstructions. We reviewed 150 cervical spine examinations and selected the most illustrative cases including congenital anomalies, degenerative lesions, spinal infections, neoplasms, traumatic injuries and postoperative abnormalities. The quality of multiplanar reformatting and volume reconstructions of the MRCT made the detection and evaluation of most of cases with complex anatomy easier and more precise. (author)

1984-01-01

The convention used in the display of the transverse sections of the human body in the plans for radiotherapy follows the editorial policy of the Journal of Computer Assisted Tomography. For the purpose of this Compendium the convention is defined as: The ''seen from above'' convention is used for the head and upper neck, in which is included the oropharynx. This is the 'anatomical convention' now used with the computed tomography (CT) head scanner and is accepted generally by neuroradiologists, neurosurgeons and neurologists. This convention is also employed in the display of isotope scans of the head. The ''seen from below'' convention is used for the rest of the body, i.e. below the level of the lower border of the third cervical vertebral body; this includes the hypopharynx, larynx and thyroid. This is the usual 'radiological convention', i.e. the patient's right is on the observer's left. This is the convention generally used in total body CT scanning of the thorax and abdomen; the same convention is used in isotope and ultrasonic imaging

Cervical Vertigo: Historical Reviews and Advances.

Peng, Baogan

2018-01-01

Vertigo is one of the most common presentations in adult patients. Among the various causes of vertigo, so-called cervical vertigo is still a controversial entity. Cervical vertigo was first thought to be due to abnormal input from cervical sympathetic nerves based on the work of Barré and Liéou in 1928. Later studies found that cerebral blood flow is not influenced by sympathetic stimulation. Ryan and Cope in 1955 proposed that abnormal sensory information from the damaged joint receptors of upper cervical regions may be related to pathologies of vertigo of cervical origin. Further studies found that cervical vertigo seems to originate from diseased cervical intervertebral discs. Recent research found that the ingrowth of a large number of Ruffini corpuscles into diseased cervical discs may be related to vertigo of cervical origin. Abnormal neck proprioceptive input integrated from the signals of Ruffini corpuscles in diseased cervical discs and muscle spindles in tense neck muscles secondary to neck pain is transmitted to the central nervous system and leads to a sensory mismatch with vestibular and other sensory information, resulting in a subjective feeling of vertigo and unsteadiness. Further studies are needed to illustrate the complex pathophysiologic mechanisms of cervical vertigo and to better understand and manage this perplexing entity. Copyright © 2017 Elsevier Inc.

Nerve-sparing radical hysterectomy (NSRH) was introduced with the aim to reduce pelvic dysfunctions related to conventional radical hysterectomy (RH). Here, we sought to assess the effectiveness and safety of NSRH in a relatively large number of the patients of cervical cancer (CC) patients undergoing either primary surgery or neoadjuvant chemotherapy (NACT) followed by surgery. Outcomes of consecutive patients undergoing NSRH and of a historical cohort of patients undergoing conventional RH were retrospectively reviewed. This study included 325 (49.8%) and 327 (50.2%) undergoing NSRH and RH, respectively. Via a multivariable model, nodal status was the only factor predicting for DFS (hazard ratio [HR]=2.09; 95% confidence interval [CI]=1.17-3.73; p=0.01). A trend towards high risk of recurrence was observed for patients affected by locally advanced cervical cancer (LACC) undergoing NACT followed by surgery (HR=2.57; 95% CI=0.95-6.96; p=0.06). Type of surgical procedures (NSRH vs. RH) did not influence risk of recurrence (p=0.47). Similarly, we observed that the execution of NSRH rather than RH had not a detrimental effect on OS (HR=1.19; 95% CI=0.16-9.01; p=0.87). Via multivariable model, no factor directly correlated with OS. No difference in early complication rates was observed between the study groups. Conversely, a significant higher number of late complications was reported in RH versus NSRH groups (p=0.02). Our data suggested that NSRH upholds effectiveness of conventional RH, without increasing recurrence and complication rates but improving pelvic dysfunction rates. Copyright © 2018.

Since the introduction of the Papanicolaou smear and colposcopy, cervical cancers can be diagnosed and treated easily in their preinvasive state. Although theoretically cancer of the cervix should be detected and treated before becoming invasive disease, there are still too many women who develop invasive cancer of the cervix and require radical surgery and/or radiation therapy. The management of patients with recurrent or advanced disease is difficult and challenging.36 references

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

Enterobiasis is one of the most common human parasitic infections. It is considered an intestinal parasite, but cases of extra-intestinal affections exist, notably infections of the female genital tract. Enterobius vermicularis (EV) eggs (or ova) have been found in the cervical smears of two patients in our institute during the last 16 years. No gynaecological or gastrointestinal symptoms were reported, and there was no known intestinal infection in these two cases. A review of the available literature revealed rare cases of vaginal enterobiasis, with a wide range of clinical presentations, many patients being asymptomatic. The diagnosis may sometimes be difficult, mainly because of the lack of clinical suspicion. However, cytological identification of EV in cervico-vaginal smears is important, especially when considering the risk of ascending infections of the genital tract associated with severe complications. © 2017 Wiley Periodicals, Inc.

In a previous article, we used the PMMA cervical cage in the treatment of single-level cervical disk disease and the preliminary clinical results were satisfactory. However, the mechanical properties of the PMMA cage were not clear. Therefore, we designed a comparative in vitro biomechanical study to determine the mechanical properties of the PMMA cage. The PMMA cervical cage and the Solis PEEK cervical cage were compressed in a materials testing machine to determine the mechanical properties. The compressive yield strength of the PMMA cage (7030 +/- 637 N) was less than that of the Solis polymer cervical cage (8100 +/- 572 N). The ultimate compressive strength of the PMMA cage (8160 +/- 724 N) was less than that of the Solis cage (9100 +/- 634 N). The stiffness of the PMMA cervical cage (8106 +/- 817 N/mm) was greater than that of the Solis cage (6486 +/- 530 N/mm). The elastic modulus of the PMMA cage (623 +/- 57 MPa) was greater than that of the Solis cage (510 +/- 42 MPa). The elongation of PMMA cage (43.5 +/- 5.7%) was larger than that of the Solis cage (36.1 +/- 4.3%). Although the compressive yield strength and ultimate compressive strength of the PMMA cervical cage were less than those of the Solis polymer cage, the mechanical properties are better than those of the cervical vertebral body. The PMMA cage is strong and safe for use as a spacer for cervical interbody fusion. Compared with other cage materials, the PMMA cage has many advantages and no obvious failings at present. However, the PMMA cervical cage warrants further long-term clinical study.

Despite the undisputed and impressive success which has been achieved since the 1960s by cervical cytology in the fight against cervical cancer and its precursor stages, during which the mortality rate in industrialized countries over the last 40 years has been reduced by two-thirds to three-quarters, a perfect and error-free screening procedure is still a long way off and will probably never be reached. There are two main reasons for this, the lack of adequate coverage and suboptimal quality and assessment of smears. Two screening procedures are in use Europe, an opportunistic and an organized system. Both systems have many advantages but also disadvantages. In organized programs the coverage is higher (up to 80%), although similar numbers are also achieved by non-organized programs over a 3-year cycle, even if they cannot be so exactly documented. The decision on which system is used depends on the health system of the country, public or non-public, and many other national circumstances. However, in both systems prerequisites for a satisfactory result is a high quality in the sampling technique, the processing and the assessment. Therefore, several guidelines have been introduced by state and medical societies for internal and external quality assurance. New technologies, such as thin-layer cytology or automation for replacement or support of conventional cytology liquid-based cytology proved not to be superior enough to justify the high costs of these systems. The recognition of the strong causal relationship between persistent infection with high-risk human papillomavirus (HPV) types and cervical cancer and its precursors has resulted in the development of comparably simple tests. Primary screening using HPV typing alone is not recommended in opportunistic screening due to the low specificity but high sensitivity because it leads to many clinically irrelevant results which place women under stress. In organized screening HPV testing is always and only possible

A discogenic cervical headache is a subtype of cervicogenic headache (CEH) that arises from a degenerative cervical disc abnormality. The purpose of this study was to evaluate the clinical outcome of percutaneous endoscopic cervical discectomy (PECD) for patients with chronic cervical headache due to soft cervical disc herniation. Seventeen patients underwent PECD for intractable headache. The inclusion criteria were soft disc herniation without segmental instability, proven by both local anesthesia and provocative discography for headache unresponsive to conservative treatment. The mean follow-up period was 37.6 months. Fifteen of the 17 patients (88.2%) showed successful outcomes based on the Macnab criteria. Pain scores on a visual analog scale (VAS) improved from a preoperative mean of 8.35±0.79 to 2.12±1.17, postoperatively (P<0.01). The mean disc height decreased from 6.81±1.08 to 5.98±1.07 mm (P<0.01). There was no newly developed segmental instability or spontaneous fusion on follow-up radiography. In conclusion, PECD appears to be effective for chronic severe discogenic cervical headache under strict inclusion criteria. (orig.)

Objective: To evaluate the stability of the goat's cervical spine after PCD (percutaneous cervical diskectomy). Methods: Ten adult goats were studied. Seven had PCD at C 3-4 , and three at C 4-5 . The cervical spine of the goat was studied with MR using axial, corona land sagittal images and with anteroposterior and lateral radiographs before and after PCD. The height of the disk, the disk space angle and dislocation were measured respectively before and after PCD. The data were examined by t-test. Results: The disk space (7 cases, 70%) became narrow obviously, and hyperostosis (5 cases, 50%) disk bulging (4 cases, 40%) appeared after PCD, but there was no obvious dislocation or angulation between the adjacent vertebral bodies. Conclusions: The stability of the goat's cervical spine is not affected after PCD. Indicating that this might also hold true for human cervical spine

Oncogenic human papilloma virus and cervical pre-cancerous lesions in brothel-based sex workers in India

Directory of Open Access Journals (Sweden)

Kamalesh Sarkar

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

Purpose: To determine the usefulness of CT angiography (CTA) and MR angiography (MRA) for evaluation of dissection in cervical vessels. Material and methods: Dissection of cervical vessels was revealed by conventional angiography in 4 patients (two female, two male) of 30-62 years of age. Dissection was located in the carotid artery (n=3) and in the vertebral artery (n=1). In two patients CTA and in two patients MRA was performed. Results: Diagnosis of dissection was possible by CTA (internal carotid artery: n=2) and by MRA (internal carotid artery and vertebral artery). Imaging of the dissection membrane of the vessel wall was possible in one case with MRA. Conclusion: CT and MR angiography was successful for detection of typical morphology of dissection in all cases. If results in a greater number can be obtained it seems to be conceivable that both methods can be used in primary diagnosis. (orig.) [de

Full Text Available Objectives. Digital impressions are increasingly used and have the potential to avoid the problem of inaccurate impressions. Only a few studies to verify the accuracy of digital impressions have been performed. The purpose of this study was to compare the marginal and internal fit of 3-unit tooth supported fixed dental prostheses (FDPs fabricated from digital and conventional impressions. Methods. Ten FDPs were produced from digital impressions using the iTero system and 10 FDPs were produced using vinyl polysiloxane (VPS impression material. A triple-scan protocol and CAD software were used for measuring and calculating discrepancies of the FDPs at 3 standard areas: mean internal discrepancy, absolute marginal gap, and cervical area discrepancy. The Mann-Whitney U test was used for analyzing the results. Results. For conventional and digital impressions, respectively, FDPs had an absolute marginal gap of 147 μm and 142 μm, cervical area discrepancy of 69 μm and 44 μm, and mean internal discrepancy of 117 μm and 93 μm. The differences were statistically significant in the cervical and internal areas (P<0.001. Significance. The results indicated that the digital impression technique is more exact and can generate 3-unit FDPs with a significantly closer fit compared to the VPS technique.

To evaluate whether or not an educational intervention would lead to a change in knowledge and attitudes about human papillomavirus (HPV), HPV vaccines, and cervical cancer. The HPV status was also investigated for interested participants. We provided HPV and cervical cancer education to urban American Indian (AI) women 18 and older using a pre and post-knowledge exam to assess knowledge and attitudes. Women were also given the option to perform vaginal self-tests for high risk HPV (hrHPV) analysis immediately after the education. Ninety-six women participated in our educational sessions. Improvement in performance on a knowledge exam increased from 61.6 to 84.3 percent. Ninety-three women performed the vaginal self-test with 63.1 percent of women preferring vaginal self-testing over conventional screening methods. Thirty-five out of 91 women (38.5 percent) had hrHPV types with 12 of the 35 harboring multiple hrHPV types (13 percent overall). HPV and cervical cancer education was beneficial for urban AI women with the majority of women preferring vaginal self-testing. HPV self-testing may be a strategy to improve screening rates for cervical cancer. Urban AI women had high rates of hrHPV compared to rural AI populations as reported in previous studies.

Weakness of cervical extensor muscles causes loss of cervical lordosis, which could also cause neck pain. The aim of this study was to investigate the impact of fat infiltration in cervical extensor muscles on cervical lordosis and neck pain. Fifty-six patients who suffered from neck pain were included in this study. Fat infiltration in cervical extensor muscles was measured at each level of C2-3 and C6-7 using axial magnetic resonance imaging. The visual analogue scale (VAS), 12-Item Short Form Health Survey (SF-12), and Neck Disability Index (NDI) were used for clinical assessment. The mean fat infiltration was 206.3 mm 2 (20.3%) at C2-3 and 240.6 mm 2 (19.5%) at C6-7. Fat infiltration in cervical extensor muscles was associated with high VAS scores at both levels ( p = 0.047 at C2-3; p = 0.009 at C6-7). At C2-3, there was a negative correlation between fat infiltration of the cervical extensor muscles and cervical lordosis (r = -0.216; p = 0.020). At C6-7, fat infiltration in the cervical extensor muscles was closely related to NDI ( p = 0.003) and SF-12 ( p > 0.05). However, there was no significant correlation between cervical lordosis and clinical outcomes (VAS, p = 0.112; NDI, p = 0.087; and SF-12, p > 0.05). These results suggest that fat infiltration in the upper cervical extensor muscles has relevance to the loss of cervical lordosis, whereas fat infiltration in the lower cervical extensor muscles is associated with cervical functional disability.

METHOD: We present the evaluation of the arthrodesis' rate and cervical alignment in 48 patients with cervical degenerative disease (CDD submitted to anterior cervical discectomy with interposition of polymethylmetacrylate (PMMA. Odom and Nürick scales were used to evaluation of functional status before and after surgery. Cervical spine X-rays were used to access arthrodesis and alignment, at least 2 years after the procedure. RESULTS: Excellent and good results (Odom I and II were obtained in 91% of the patients with radiculopathy and in 69% of those with myelopathy. Using the chi square test of independence (1% of significance, there was no association between excellent and good clinical results with the presence of arthrodesis verified in cervical X-rays. The presence of cervical alignment had association with good results, whereas the misalignment was associated with unfavorable outcomes. Two patients died: one cervical hematoma and other from graft migration with cord compression. CONCLUSIONS: Cervical alignment was more important than fusion to achieve good surgical results in CDD.TEMA E OBJETIVO: O tratamento cirúrgico da radiculopatia cervical com ou sem mielopatia é um tema controverso, embora a discectomia por via anterior seja uma das formas mais comuns de tratamento.

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.

Retrospective study. To assess the relationship between sagittal alignment of the cervical spine and patient-reported health-related quality-of-life scores following multilevel posterior cervical fusion, and to explore whether an analogous relationship exists in the cervical spine using T1 slope minus C2-C7 lordosis (T1S-CL). A recent study demonstrated that, similar to the thoracolumbar spine, the severity of disability increases with sagittal malalignment following cervical reconstruction surgery. From 2007 to 2013, 38 consecutive patients underwent multilevel posterior cervical fusion for cervical stenosis, myelopathy, and deformities. Radiographic measurements included C0-C2 lordosis, C2-C7 lordosis, C2-C7 sagittal vertical axis (SVA), T1 slope, and T1S-CL. Pearson correlation coefficients were calculated between pairs of radiographic measures and health-related quality-of-life. C2-C7 SVA positively correlated with neck disability index (NDI) scores (r = 0.495). C2-C7 lordosis (P = 0.001) and T1S-CL (P = 0.002) changes correlated with NDI score changes after surgery. For significant correlations between C2-C7 SVA and NDI scores, regression models predicted a threshold C2-C7 SVA value of 50 mm, beyond which correlations were most significant. The T1S-CL also correlated positively with C2-C7 SVA and NDI scores (r = 0.871 and r = 0.470, respectively). Results of the regression analysis indicated that a C2-C7 SVA value of 50 mm corresponded to a T1S-CL value of 26.1°. This study showed that disability of the neck increased with cervical sagittal malalignment following surgical reconstruction and a greater T1S-CL mismatch was associated with a greater degree of cervical malalignment. Specifically, a mismatch greater than 26.1° corresponded to positive cervical sagittal malalignment, defined as C2-C7 SVA greater than 50 mm. 3.

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 vertigo is characterized by vertigo from the cervical spine. However, whether cervical vertigo is an independent entity still remains controversial. In this narrative review, we outline the basic science and clinical evidence for cervical vertigo according to the current literature. So far, there are 4 different hypotheses explaining the vertigo of a cervical origin, including proprioceptive cervical vertigo, Barré-Lieou syndrome, rotational vertebral artery vertigo, and migraine-associated cervicogenic vertigo. Proprioceptive cervical vertigo and rotational vertebral artery vertigo have survived with time. Barré-Lieou syndrome once was discredited, but it has been resurrected recently by increased scientific evidence. Diagnosis depends mostly on patients' subjective feelings, lacking positive signs, specific laboratory examinations and clinical trials, and often relies on limited clinical experiences of clinicians. Neurological, vestibular, and psychosomatic disorders must first be excluded before the dizziness and unsteadiness in cervical pain syndromes can be attributed to a cervical origin. Treatment for cervical vertigo is challenging. Manual therapy is recommended for treatment of proprioceptive cervical vertigo. Anterior cervical surgery and percutaneous laser disc decompression are effective for the cervical spondylosis patients accompanied with Barré-Liéou syndrome. As to rotational vertebral artery vertigo, a rare entity, when the exact area of the arterial compression is identified through appropriate tests such as magnetic resonance angiography (MRA), computed tomography angiography (CTA) or digital subtraction angiography (DSA) decompressive surgery should be the chosen treatment.

The Biomechanics of Cervical Spondylosis

Directory of Open Access Journals (Sweden)

Lisa A. Ferrara

2012-01-01

Full Text Available Aging is the major risk factor that contributes to the onset of cervical spondylosis. Several acute and chronic symptoms can occur that start with neck pain and may progress into cervical radiculopathy. Eventually, the degenerative cascade causes desiccation of the intervertebral disc resulting in height loss along the ventral margin of the cervical spine. This causes ventral angulation and eventual loss of lordosis, with compression of the neural and vascular structures. The altered posture of the cervical spine will progress into kyphosis and continue if the load balance and lordosis is not restored. The content of this paper will address the physiological and biomechanical pathways leading to cervical spondylosis and the biomechanical principles related to the surgical correction and treatment of kyphotic progression.

Purpose: In the context of evaluating dosimetric impacts of a variety of uncertainties involved in HDR Tandem-and-Ovoid treatment, to study the correlations between conventional point doses and 3D volumetric doses. Methods: For 5 cervical cancer patients treated with HDR T&O, 150 plans were retrospectively created to study dosimetric impacts of the following uncertainties: (1) inter-fractional applicator displacement between two treatment fractions within a single insertion by applying Fraction#1 plan to Fraction#2 CT; (2) positional dwell error simulated from −5mm to 5mm in 1mm steps; (3) simulated temporal dwell error of 0.05s, 0.1s, 0.5s, and 1s. The original plans were based on point dose prescription, from which the volume covered by the prescription dose was generated as the pseudo target volume to study the 3D target dose effect. OARs were contoured. The point and volumetric dose errors were calculated by taking the differences between original and simulated plans. The correlations between the point and volumetric dose errors were analyzed. Results: For the most clinically relevant positional dwell uncertainty of 1mm, temporal uncertainty of 0.05s, and inter-fractional applicator displacement within the same insertion, the mean target D90 and V100 deviation were within 1%. Among these uncertainties, the applicator displacement showed the largest potential target coverage impact (2.6% on D90) as well as the OAR dose impact (2.5% and 3.4% on bladder D2cc and rectum D2cc). The Spearman correlation analysis shows a correlation coefficient of 0.43 with a p-value of 0.11 between target D90 coverage and H point dose. Conclusion: With the most clinically relevant positional and temporal dwell uncertainties and patient interfractional applicator displacement within the same insertion, the dose error is within clinical acceptable range. The lack of correlation between H point and 3D volumetric dose errors is a motivator for the use of 3D treatment planning in

Objectives. Reproductive health screenings are a necessary part of quality health care. However, sexual minorities underutilize Papanicolaou (Pap) tests more than heterosexuals do, and the reasons are not known. Our objective was to examine if less hormonal contraceptive use or less positive health beliefs about Pap tests explain sexual orientation disparities in Pap test intention and utilization. Methods. We used multivariable regression with prospective data gathered from 3821 females aged 18 to 25 years in the Growing Up Today Study (GUTS). Results. Among lesbians, less hormonal contraceptive use explained 8.6% of the disparities in Pap test intention and 36.1% of the disparities in Pap test utilization. Less positive health beliefs associated with Pap testing explained 19.1% of the disparities in Pap test intention. Together, less hormonal contraceptive use and less positive health beliefs explained 29.3% of the disparities in Pap test intention and 42.2% of the disparities in Pap test utilization. Conclusions. Hormonal contraceptive use and health beliefs, to a lesser extent, help to explain sexual orientation disparities in intention and receipt of a Pap test, especially among lesbians. PMID:23763393

Full Text Available Abstract Background The cervical muscles are considered a potential site of whiplash injury, and there is a need to understand the cervical muscle response under non-conventional whiplash impact scenarios, including variable body position and impact direction. There is no data, however, on the effect of occupant position on the muscle response to frontal impacts. Therefore, the objective of the study was to measure cervical muscle response to graded right anterolateral impacts. Methods Twenty volunteers were subjected to right anterolateral impacts of 4.3, 7.8, 10.6, and 12.8 m/s2 acceleration with their trunk flexed forward 45 degrees and laterally flexed right or left by 45 degrees. Bilateral EMG of the sternocleidomastoids, trapezii, and splenii capitis and acceleration of the sled, torso, and head were measured. Results and discussion With either direction of trunk flexion at impact, the trapezius EMGs increased with increasing acceleration (p Conclusion When the subject sits with trunk flexed out of neutral posture at the time of anterolateral impact, the cervical muscle response is dramatically reduced compared to frontal impacts with the trunk in neutral posture. In the absence of bodily impact, the flexed trunk posture appears to produce a biomechanical response that would decrease the likelihood of cervical muscle injury in low velocity impacts.

Cervical cancer is the fourth most common malignancy diagnosed in women worldwide. Nearly all cases of cervical cancer result from infection with the human papillomavirus, and the prevention of cervical cancer includes screening and vaccination. Primary treatment options for patients with cervical cancer may include surgery or a concurrent chemoradiotherapy regimen consisting of cisplatin-based chemotherapy with external beam radiotherapy and brachytherapy. Cervical cancer causes more than one quarter of a million deaths per year as a result of grossly deficient treatments in many developing countries. This warrants a concerted global effort to counter the shocking loss of life and suffering that largely goes unreported. This article provides a review of the biology, prevention, and treatment of cervical cancer, and discusses the global cervical cancer crisis and efforts to improve the prevention and treatment of the disease in underdeveloped countries.

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.

Expansive open-door laminoplasty (EOLP) is a useful technique for multiple-level cervical spondylotic myelopathy. The common postoperative complications of EOLP include moderate to severe neck pain, loss of cervical lordosis, decrease of cervical range of motion, and C5 palsy. We modified the surgical technique to lessen these complications. This study is aimed to elucidate the efficacy of modified techniques to lessen the complications of traditional procedures. We collected data from 126 consecutive patients treated at our institution between August 2008 and December 2012. Of these, 66 patients underwent conventional EOLP (CEOLP) and the other 60 patients underwent modified EOLP (MEOLP). The demographic and preoperative data, axial pain visual analog scale scores at 2 weeks and 3 months postoperatively, clinical outcomes evaluated using Nurick score and Japanese Orthopedic Association recovery rate at 12 months postoperatively, and radiographic results assessed using plain films at 3 months and 12 months postoperatively for both groups were compared and analyzed. There were no significant differences regarding the preoperative condition between the CEOLP and MEOLP groups (p > 0.05). The Japanese Orthopedic Association recovery rate of the MEOLP group was 70.3%, comparable to the result of the other group (70.2%). Postoperative axial neck pain, loss of range of motion, and loss of lordosis of cervical curvature decreased significantly in the MEOLP group (p cervical spondylotic myelopathy, which decreases postoperative complications effectively.

Full Text Available Involvement of the cervical spine is common in rheumatoid arthritis. Clinical presentation can be variable, and symptoms may be due to neck pain or compressive myeloradiculopathy. We discuss the pathology, grading systems, clinical presentation, indications for surgery and surgical management of cervical myelopathy related to rheumatoid arthritis in this paper. We describe our surgical technique and results. We recommend early consultation for surgical management when involvement of the cervical spine is suspected in rheumatoid arthritis. Even patients with advanced cervical myelopathy should be discussed for surgical treatment, since in our experience improvement in function after surgery is common.

Purpose: To evaluate the magnitude of cervix regression and motion during external beam chemoradiation for cervical cancer. Methods and Materials: Sixteen patients with cervical cancer underwent computed tomography scanning before, weekly during, and after conventional chemoradiation. Cervix volumes were calculated to determine the extent of cervix regression. Changes in the center of mass and perimeter of the cervix between scans were used to determine the magnitude of cervix motion. Maximum cervix position changes were calculated for each patient, and mean maximum changes were calculated for the group. Results: Mean cervical volumes before and after 45 Gy of external beam irradiation were 97.0 and 31.9 cc, respectively; mean volume reduction was 62.3%. Mean maximum changes in the center of mass of the cervix were 2.1, 1.6, and 0.82 cm in the superior-inferior, anterior-posterior, and right-left lateral dimensions, respectively. Mean maximum changes in the perimeter of the cervix were 2.3 and 1.3 cm in the superior and inferior, 1.7 and 1.8 cm in the anterior and posterior, and 0.76 and 0.94 cm in the right and left lateral directions, respectively. Conclusions: Cervix regression and internal organ motion contribute to marked interfraction variations in the intrapelvic position of the cervical target in patients receiving chemoradiation for cervical cancer. Failure to take these variations into account during the application of highly conformal external beam radiation techniques poses a theoretical risk of underdosing the target or overdosing adjacent critical structures

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).

Purpose: To perform an intracavitary radiotherapy (ICR) plan comparison between the conventional point A plan (conventional plan) and computed tomography (CT)-guided clinical target volume-based plan (CTV plan) by analysis of the quantitative dose-volume parameters and irradiated volumes of organs at risk in patients with cervical cancer. Methods and Materials: Thirty plans for 192 Ir high-dose-rate ICR after 30-40-Gy external beam radiotherapy were investigated. CT images were acquired at the first ICR session with artifact-free applicators in place. The gross tumor volume, clinical target volume (CTV), point A, and International Commission on Radiation Units and Measurements Report 38 rectal and bladder points were defined on reconstructed CT images. A fractional 100% dose was prescribed to point A in the conventional plan and to the outermost point to cover all CTVs in the CTV plan. The reference volume receiving 100% of the prescribed dose (V ref ), and the dose-volume parameters of the coverage index, conformal index, and external volume index were calculated from the dose-volume histogram. The bladder, rectal point doses, and percentage of volumes receiving 50%, 80%, and 100% of the prescribed dose were also analyzed. Results: Conventional plans were performed, and patients were categorized on the basis of whether the 100% isodose line of point A prescription dose fully encompassed the CTV (Group 1, n = 20) or not (Group 2, n = 10). The mean gross tumor volume (11.6 cm 3 ) and CTV (24.9 cm 3 ) of Group 1 were smaller than the corresponding values (23.7 and 44.7 cm 3 , respectively) for Group 2 (p = 0.003). The mean V ref for all patients was 129.6 cm 3 for the conventional plan and 97.0 cm 3 for the CTV plan (p = 0.003). The mean V ref in Group 1 decreased markedly with the CTV plan (p < 0.001). For the conventional and CTV plans in all patients, the mean coverage index, conformal index, and external volume index were 0.98 and 1.0, 0.23 and 0.34, and 3.86 and

Cervical spinal cord injuries in patients with cervical spondylosis.

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.

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

Acute cervical spinal cord injury (SCI) has been observed in some patients after a minor trauma to the cervical spine. The discrepancy between the severity of the trauma and the clinical symptoms has been attributed to spinal canal stenosis. However, to date, there is no universally established radiological parameter for identifying critical spinal stenosis in these patients. The spinal canal-to-vertebral body ratio (Torg-Pavlov ratio) has been proposed for assessing developmental spinal canal stenosis. The relevance of the Torg-Pavlov ratio for predicting the occurrence and severity of acute cervical SCI after a minor trauma to the cervical spine has not yet been established. To investigate the Torg-Pavlov ratio values of the cervical spine in patients suffering from acute cervical SCI after a minor trauma to the cervical spine and the use of the Torg-Pavlov ratio for identifying patients at risk of cervical SCI and predicting the severity and course of symptoms. Retrospective radiological study of consecutive patients. Forty-five patients suffering from acute cervical SCI and 68 patients showing no neurologic symptoms after a minor trauma to the cervical spine. Midvertebral sagittal cervical spinal canal diameter and the sagittal vertebral body diameter. Calculation of the Torg-Pavlov ratio values. Conventional lateral radiographs of the cervical spine (C3-C7) were analyzed to determine the Torg-Pavlov ratio values. Receiver operating characteristic curves were calculated for evaluating the classification accuracy of the Torg-Pavlov ratio for predicting SCI. The Torg-Pavlov ratio values in the SCI group were significantly (pPavlov ratio cutoff value of 0.7 yielded the greatest positive likelihood ratio for predicting the occurrence of SCI. However, there were no significant differences in the Torg-Pavlov ratio values between the different American Spinal Injury Association Impairment Score groups and between patients with complete, partial, and no recovery of

Cervical cancer is a major disease with high mortality. All cervical cancers are caused by infection with human papillomaviruses (HPV). Although preventive vaccines for cervical cancer are successful, treatment of cervical cancer is far less satisfactory because of multidrug resistance and side effects. In this review, we summarize the recent application of nanotechnology to the diagnosis and treatment of cervical cancer as well as the development of HPV vaccines. Early detection of cervical cancer enables tumours to be efficiently removed by surgical procedures, leading to increased survival rate. The current method of detecting cervical cancer by Pap smear can only achieve 50% sensitivity, whereas nanotechnology has been used to detect HPVs with greatly improved sensitivity. In cervical cancer treatment, nanotechnology has been used for the delivery of anticancer drugs to increase treatment efficacy and decrease side effects. Nanodelivery of HPV preventive and therapeutic vaccines has also been investigated to increase vaccine efficacy. Overall, these developments suggest that nanoparticle-based vaccine may become the most effective way to prevent and treat cervical cancer, assisted or combined with some other nanotechnology-based therapy.

Moatz, Bradley; Tortolani, P Justin

2012-01-01

Cervical disc arthroplasty has emerged as a promising potential alternative to anterior cervical discectomy and fusion (ACDF) in appropriately selected patients. Despite a history of excellent outcomes after ACDF, the question as to whether a fusion leads to adjacent segment degeneration remains unanswered. Numerous US investigational device exemption trials comparing cervical arthroplasty to fusion have been conducted to answer this question. This study reviews the current research regarding cervical athroplasty, and emphasizes both the pros and cons of arthroplasty as compared with ACDF. Early clinical outcomes show that cervical arthroplasty is as effective as the standard ACDF. However, this new technology is also associated with an expanding list of novel complications. Although there is no definitive evidence that cervical disc replacement reduces the incidence of adjacent segment degeneration, it does show other advantages; for example, faster return to work, and reduced need for postoperative bracing.

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

Most of the cases of ischaemic stroke in our setting are of atherothrombotic origin. Detecting intracranial and cervical carotid artery stenosis in patients with ischaemic stroke is therefore essential. Ultrasonography has become the tool of choice for diagnosing carotid artery stenosis because it is both readily accessibility and reliable. However, use of this technique must be validated in each laboratory. The purpose of this study is to validate Doppler ultrasound in our laboratory as a means of detecting severe carotid artery stenosis. We conducted an observational descriptive study to evaluate diagnostic tests. The results from transcranial and cervical carotid Doppler ultrasound scans conducted by neurologists were compared to those from carotid duplex scans performed by radiologists in patients diagnosed with stroke. Arteriography was considered the gold standard (MR angiography, CT angiography, or conventional arteriography). Our sample included 228 patients. Transcranial and cervical carotid Doppler ultrasound showed a sensitivity of 95% and specificity of 100% for detection of carotid artery stenosis > 70%, whereas carotid duplex displayed a sensitivity of 87% and a specificity of 94%. Transcranial carotid Doppler ultrasound achieved a sensitivity of 78% and a specificity of 98% for detection of intracranial stenosis. Doppler ultrasound in our neurosonology laboratory was found to be a useful diagnostic tool for detecting cervical carotid artery stenosis and demonstrated superiority to carotid duplex despite the lack of B-mode. Furthermore, this technique was found to be useful for detecting intracranial stenosis. Copyright © 2017 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U. All rights reserved.

Full Text Available Abstract Background High-risk HPV DNA testing has been proposed as a primary tool for cervical cancer screening (HPV-CCS as an alternative to the Papanicolaou cytology- method. This study describes factors associated with women’s intentions to attend cervical cancer screening if high-risk HPV DNA testing (HPV-CCS was implemented as a primary screening tool, and if screening were conducted every 4 years starting after age 25. Methods This online survey was designed using the Theory of Planned Behaviour to assess factors that impact women’s intentions to attend HPV-CCS among women aged 25–69 upon exit of the HPV FOCAL trial. Univariate and regression analyses were performed to compare the demographic, sexual history, and smoking characteristics between women willing and unwilling to screen, and scales for intention to attend HPV-CCS. A qualitative analysis was performed by compiling and coding the comments section of the survey. Results Of the 981 women who completed the survey in full, only 51.4 % responded that they intended to attend HPV-CCS with a delayed start age and extended screening interval. Women who intended to screen were more likely to have higher education (AOR 0.59, 95 % CI [0.37, 0.93], while both positive attitudes (AOR 1.26, 95 % CI [1.23, 1.30] and perceived behavior control (AOR 1.06, 95 % CI [1.02, 1.10] were significant predictors of intention to screen. Among women who provided comments in the survey, a large number of women expressed fears about not being checked more than every 4 years, but 12 % stated that these fears may be alleviated by having more information. Conclusions Acceptability of increased screening intervals and starting age could be improved through enhanced education of benefits. Program planners should consider measures to assess and improve women’s knowledge, attitudes and beliefs prior to the implementation of new screening programs to avoid unintended consequences.

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.

We collected the samples of cervical intervertebral discs from patients with vertigo to examine the distribution and types of mechanoreceptors in diseased cervical disc. The aim of this study was to determine whether mechanoreceptors are distributed more abundantly in cervical discs from patients with cervical spondylosis, and whether they are related to vertigo. Previous limited studies have found that normal cervical intervertebral discs are supplied with mechanoreceptors that have been considered responsible for proprioceptive functions. Several clinical studies have indicated that the patients with cervical spondylosis manifested significantly impaired postural control and subjective balance disturbance. We collected 77 samples of cervical discs from 62 cervical spondylosis patients without vertigo, 61 samples from 54 patients with vertigo, and 40 control samples from 8 cadaveric donors to investigate distribution of mechanoreceptors containing neurofilament (NF200) and S-100 protein immunoreactive nerve endings. The immunohistochemical investigation revealed that the most frequently encountered mechanoreceptors were the Ruffini corpuscles in all groups of cervical disc samples. They were obviously increased in the number and deeply ingrown into inner annulus fibrosus and even into nucleus pulposus in the diseased cervical discs from patients with vertigo in comparison with the discs from patients without vertigo and control discs. Only three Golgi endings were seen in the three samples from patients with vertigo. No Pacinian corpuscles were found in any samples of cervical discs. The diseased cervical discs from patients with vertigo had more abundant distribution of Ruffini corpuscles than other discs. A positive association between the increased number and ingrowth of Ruffini corpuscles in the diseased cervical disc and the incidence of vertigo in the patients with cervical spondylosis was found, which may indicate a key role of Ruffini corpuscles in the

Cervical spondylosis anatomy: pathophysiology and biomechanics.

Science.gov (United States)

Shedid, Daniel; Benzel, Edward C

Cervical spondylosis is the most common progressive disorder in the aging cervical spine. It results from the process of degeneration of the intervertebral discs and facet joints of the cervical spine. Biomechanically, the disc and the facets are the connecting structures between the vertebrae for the transmission of external forces. They also facilitate cervical spine mobility. Symptoms related to myelopathy and radiculopathy are caused by the formation of osteophytes, which compromise the diameter of the spinal canal. This compromise may also be partially developmental. The developmental process, together with the degenerative process, may cause mechanical pressure on the spinal cord at one or multiple levels. This pressure may produce direct neurological damage or ischemic changes and, thus, lead to spinal cord disturbances. A thorough understanding of the biomechanics, the pathology, the clinical presentation, the radiological evaluation, as well as the surgical indications of cervical spondylosis, is essential for the management of patients with cervical spondylosis.

Imaging of the cervical articular pillar

The cervical articular pillar, due to the complex anatomical structure of the cervical spine, is not well demonstrated in routine plain radiographic views. Dedicated views have been devised to demonstrate the pillar, yet their performance has abated considerably since the inception of Computed Tomography (CT) in the 1970`s. It is the consideration that CT does not image the articular pillar with a 10 per cent accuracy that poses the question: Is there still a need for plain radiography of the cervical articular pillar? This paper studies the anatomy, plain radiography, and incidence of injury to the cervical articular pillar. It discusses (with reference to current and historic literature) the efficacy of current imaging protocols in depicting this injury. It deals with plain radiography, CT, complex tomography, and Magnetic Resonance Imaging (MRI) of the cervical spine to conclude there may still be a position in current imaging protocols for plain radiography of the cervical articular pillar.

To verify the conventional concept of ''developmental stenosis of the cervical spinal canal'', we performed a morphological analysis of the relations of the cervical spinal canal, dural tube and spinal cord in normal individuals. The sagittal diameter, area and circularity of the three structures, and the dispersion of each parameter, were examined on axial sections of CT myelograms of 36 normal subjects. The spinal canal was narrowest at C4, followed by C5, while the spinal cord was largest at C4/5. The area and circularity of the cervical spinal cord were not significantly correlated with any parameter of the spinal canal nor with the sagittal diameter and area of the dural tube at any level examined, and the spinal cord showed less individual variation than the bony canal. Compression of the spinal cord might be expected whenever the sagittal diameter of the spinal canal is below the lower limit of normal, that is about 12 mm on plain radiographs. Thus, we concluded that the concept of ''developmental stenosis of the cervical spinal canal'' was reasonable and acceptable. (orig.). With 2 figs., 3 tabs

In two cases of accidents occuring during bathing, one football accident and a toboggan accident, the injuries concerned point to hyperextension of the cervical spine as cause of the injury. In another football accident and a riding accident, the changes observed allow us to conclude that the movement leading to the injury must have been a hyperflexion. One accident occurring while jumping on the trampolin resulted in an injury of the upper cervical spine pointing to the action of a compressive force on the cervical spine in addition to the force resulting in hyperflexion.

To provide normative values for cervical range of motion (CROM), isometric cervical and shoulder strength for; International Senior professional, and International Age-grade Rugby Union front-row forwards. Cross-sectional population study. All international level front-row players within a Rugby Union Tier 1 Nation. Nineteen Senior and 21 Age-grade front-row forwards underwent CROM, cervical and shoulder strength testing. CROM was measured using the CROM device and the Gatherer System was used to measure multi-directional isometric cervical and shoulder strength. The Age-grade players had significantly lower; cervical strength (26-57% deficits), cervical flexion to extension strength ratios (0.5 vs. 0.6), and shoulder strength (2-36% deficits) than the Senior players. However, there were no differences between front-row positions within each age group. Additionally, there were no differences between age groups or front-row positions in the CROM measurements. Senior Rugby Union front-row forwards have greater cervical and shoulder strength than Age-grade players, with the biggest differences being in cervical strength, highlighting the need for age specific normative values. Importantly, Age-grade players should be evaluated to ensure they have developed sufficient cervical strength prior to entering professional level Rugby Union. Copyright © 2015 Elsevier Ltd.

2012-09-15

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

Cervical cancer is the second most frequent cancer in woman in developing countries and one of the most crucial health problems in the world. Human Papillomavirus (HPV) is an agent for sexually transmitted disease which is an act of cervical cancer, especially high-risk of HPV type 16 and 18. In this study, we investigated the Pap smear cytology features and identification of HPV types 16 and18 in multiparity women at Aviati Clinic Padang Bulan, Medan. Samples are cervical swabs of 50 multiparity women who met the inclusion criteria (childbirth ≥ three times) was included in the study. Pap smear examination was conducted using Papanicolaou staining and identification of HPV types 16 and 18 using the Polymerase Chain Reactive (PCR) methods.

INTRODUCTION: Preterm cervical shortening and cervical insufficiency may be caused by a constitutional weakness of the cervix. The aim of this study was to assess the cervical collagen concentration in non-pregnant women with a history of cervical insufficiency or of a short cervix in the second...... trimester of pregnancy. MATERIAL AND METHODS: In this case-control study we included non-pregnant women one year or more after pregnancy: 55 controls with a history of normal delivery; 27 women with a history of cervical insufficiency; and 10 women with a history of a short cervix (... women with a history of a long cervix (>95th percentile) at gestational weeks 18-20. We obtained biopsies (3 × 3-4 mm) from the ectocervix and determined the collagen concentration by measuring the hydroxyproline concentration. RESULTS: Women with cervical insufficiency had lower collagen concentrations...

This study was designed to compare the accuracy of magnetic resonance imaging (MRI), myelography and computed tomography in the assessment of degenerative cervical spinal stenosis. We prospectively examined a total of 75 spinal segments in 18 patients with suspected cervical spinal canal stenosis, using sagittal spin-echo and axial gradient-echo sequences generated by a 1.5 Tesla imager, conventional myelography, and computed tomography with intrathecal contrast medium (CT-myelography). The degree of stenosis was often overestimated using MRI. This error was most prominent in cases of severe stenosis but was significant with minor to moderate stenosis. In these cases, the clinical consequences of such an overestimation can be serious, because treatment is misdirected. The error is probably caused by pulsation of the cerebrospinal fluid and truncation artefact (Gibbs phenomenon). MRI at 1.5 Tesla is thus frequently inadequate for diagnostic assessment of degenerative cervical spinal stenosis. Myelography and myelographic CT are still useful for decisions on operative treatment, especially in cases of moderate stenosis. This may, however, not apply to imagers operating at 0.5 Tesla as below. (orig.)

Full Text Available Abstract Background A cautious outlook towards neck injuries has been the norm to avoid missing cervical spine injuries. Consequently there has been an increased use of cervical spine radiography. The Canadian Cervical Spine rule was proposed to reduce unnecessary use of cervical spine radiography in alert and stable patients. Our aim was to see whether applying the Canadian Cervical Spine rule reduced the need for cervical spine radiography without missing significant cervical spine injuries. Methods This was a retrospective study conducted in 2 hospitals. 114 alert and stable patients who had cervical spine radiographs for suspected neck injuries were included in the study. Data on patient demographics, high risk & low risk factors as per the Canadian Cervical Spine rule and cervical spine radiography results were collected and analysed. Results 28 patients were included in the high risk category according to the Canadian Cervical Spine rule. 86 patients fell into the low risk category. If the Canadian Cervical Spine rule was applied, there would have been a significant reduction in cervical spine radiographs as 86/114 patients (75.4% would not have needed cervical spine radiograph. 2/114 patients who had significant cervical spine injuries would have been identified when the Canadian Cervical Spine rule was applied. Conclusion Applying the Canadian Cervical Spine rule for neck injuries in alert and stable patients would have reduced the use of cervical spine radiographs without missing out significant cervical spine injuries. This relates to reduction in radiation exposure to patients and health care costs.

To explore the relationship between cervical spine and the global spine alignment and to postulate the hypotheses that a lordotic alignment of cervical spine is not the only standard to identify asymptomatic subjects, and the degenerative modification of cervical curves depends primarily on their spinal-pelvic alignment. A cohort of 120 cases of Chinese asymptomatic subjects and a cohort of 121 cases of Chinese cervical spondylotic patients were recruited prospectively from 2011 to 2012. Roussouly Classification was utilized to categorize all subjects and patients according to their thoracic spine, lumbar spine and pelvic alignment. The cervical alignments were evaluated as lordosis, straight, sigmoid or kyphosis. Through the lateral X-ray images of neutral cervical and global spine, a number of parameters were measured and analyzed, including pelvic incidence, pelvic tilt, sacral slope, thoracic kyphosis (TK), lumbar lordosis, global cervical angles (angles between two lines parallel with posterior walls of C2 and C7), practical cervical angles (the addition of different cervical end plate angles from C3 to C7, and inter-vertebral angles from C23 to C67), T1 slope, spinal sacral angles (SSA), Hip to C7/Hip to Sacrum and C0-C2 angle. The percentages of cervical lordosis were 28.3% and 36.4% in asymptomatic and spondylotic group, respectively. The cervical spine alignments correlated with Roussouly types of global spine alignment in both asymptomatic and cervical spondylotic group (P inter-vertebral angle in Roussouly Type 2 at C4-5 and C5-6 levels (P = 0.04 and 0.04, respectively), and in Roussouly Type 3 at C6-7 level (P = 0.01). The SSA showed significant difference between Roussouly Type 2 and 4 in asymptomatic subjects (P = 0.00), and between Type 1 and 3, 1 and 4, 2 and 3, 2 and 4 in cervical spondylotic patients (P = 0.01, 0.02, 0.00 and 0.01, respectively). The T1 slope was significantly different among Roussouly types (P = 0.04) with its largest value in

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

Degenerative spondylolisthesis of the cervical spine has received insufficient attention in contrast to that of the lumbar spine. The authors analyzed the functional significance of anterior and posterior degenerative spondylolisthesis (anterolisthesis and retrolisthesis) of the cervical spine to elucidate its role in the development of cervical spondylotic myelopathy (CSM) in the elderly. A total of 79 patients aged 65 or older who eventually had surgical treatment for CSM were evaluated radiographically. Altogether, 24 patients (30%) had displacement of 3.5 mm or more (severe spondylolisthesis group), 31 had displacement of 2.0-3.4 mm (moderate spondylolisthesis group), and 24 had less than 2.0 mm displacement (mild spondylolisthesis group). The severe spondylolisthesis group consisted of 14 patients with anterolisthesis (anterolisthesis group) and 10 patients with retrolisthesis (retrolisthesis group). Patients with severe spondylolisthesis had a high incidence (93%) of degenerative spondylolisthesis at C3/4 or C4/5 and significantly greater cervical mobility than those with mild spondylolisthesis. The anterolisthesis group, but not the retrolisthesis group, had a significantly wider spinal canal than the mild spondylolisthesis group, although the degree of horizontal displacement and cervical mobility did not differ significantly between the anterolisthesis and retrolisthesis groups. Severe cord compression seen on T1-weighted magnetic resonance imaging (MRI) scans and high-intensity spinal cord signals seen on T2-weighted MRI scans corresponded significantly to the levels of the spondylolisthesis. Degenerative spondylolisthesis is not a rare radiographic finding in elderly patients with CSM, which tends to cause intense cord compression that is seen on MRI scans. Greater mobility of the upper cervical segments may be a compensatory reaction for advanced disc degeneration of the lower cervical segments, leading to the development of degenerative

Although cervical spondylosis is a common disorder, dysphagia induced by osteophyte formation is uncommon. Fewer than one hundred cases of cervical osteophyte induced dysphagia have been reported, with little attention to the diagnosis by barium swallow. The radiological features of two cases treated surgically with good results are described. Both cases complained of dysphagia while one had associated respiratory obstruction on forward flexion of his neck. The features on barium study of cervical osteophytes causing dysphagia include deformity at the level of osteophyte formation, in both AP and lateral projections. Tracheal aspirations due to deformity at the laryngeal inlet and interference with epiglottic retroversion may be present. 8 refs., 3 figs

The loss of regional cervical sagittal alignment and the progressive development of cervical kyphosis is a factor in the advancement of myelopathy. Adequate decompression of the spinal canal along with reestablishment of cervical lordosis are desired objective with regard to the surgical treatment of patients with cervical spondylotic myelopathy. A retrospective chart review was conducted in which patients who underwent either a combined anterior/posterior instrumentation and decompression or a posterior alone instrumentation and decompression for the treatment of CSM at our institution were identified. Any patient undergoing operative intervention for trauma, infection or tumors were excluded. Similarly, patients undergoing posterior instrumentation with constructs extending beyond the level of C2-C7 were similarly excluded from this study. A total of 67 patients met the inclusion criteria for this study. A total of 32 patients underwent posterior alone surgery and the remaining 35 underwent combined anterior/posterior procedure. Radiographic evaluation of patient's preoperative and postoperative cervical lordosis as measured by the C2-C7 Cobb angle was performed. Each patient's preoperative and postoperative functional disability as enumerated by the Nurick score was also recorded. Statistical analysis was conducted to determine if there was a significant relationship between improvement in cervical lordosis and improvement in patient's clinical outcomes as enumerated by the Nurick Score in patients undergoing posterior alone versus combined anterior/posterior decompression, instrumentation and fusion of the cervical spine.

Analysis of aberrant methylation of tumor suppressor genes can be used as a prognostic and predictive biomarker for cancer. In this study, we propose a colorimetric method for the detection of DNA methylation of the paired box gene 1 (PAX1 gene in cervical scrapings obtained from 42 patients who underwent cervical colposcopic biopsy. Methods: A thiolated methylation-specific polymerase chain reaction (MSP primer was used to generate MSP products labeled with the thiol group at one end. After bisulfite conversion and MSP amplification, the unmodified gold nanoparticles (AuNPs were placed in a reaction tube and NaCl was added to induce aggregation of bare AuNPs without generating polymerase chain reaction products. After salt addition, the color of AuNPs remained red in the methylated PAX1 gene samples because of binding to the MSP-amplified products. By contrast, the color of the AuNP colloid solution changed from red to blue in the non-methylated PAX1 gene samples because of aggregation of AuNPs in the absence of the MSP-amplified products. Furthermore, PAX1 methylation was quantitatively detected in cervical scrapings of patients with varied pathological degrees of cervical cancer. Conventional quantitative MSP (qMSP was also performed for comparison. Results: The two methods showed a significant correlation of the methylation frequency of the PAX1 gene in cervical scrapings with severity of cervical cancer (n=42, P<0.05. The results of the

Full Text Available Women with high-grade cervical intraepithelial neoplasia (CIN are at increased risk for developing cervical cancer. We examine how women with high-grade CIN perceive their own risk, and about pertinent knowledge concerning human high-risk papillomavirus (HPV, CIN and cervical cancer.All patients who underwent first-time treatment of high-grade CIN (grade 2+ were followed-up at 6-months at the Karolinska University Hospital, Stockholm, Sweden and were invited to participate in the present study. This included completion of a questionnaire examining sociodemographic characteristics, self-perceived risk of cervical cancer without regular gynecologic follow-up, and 14 queries about HPV, CIN and cervical cancer knowledge, inter alia.The participation rate was 96.6%, with 479 women enrolled in this study. Over 75% were age 40 or younger, over half had completed university education. Most were married or co-living with their partner and were gainfully employed. On a scale scored from 10 (highest self-perceived risk of cervical cancer without regular gynecologic follow-up to 1 (lowest self-perceived risk, 64% rated their risk ≥ 7; almost 30% viewed their risk ≤ 6 and 7.5% did not rate their risk. A Specific Knowledge Scale with six of the queries explained 58.3% of the total variance. Nearly 30% of the women answered four or fewer of the six queries correctly. The Specific Knowledge Scale predicted self-perceived cervical cancer risk (Odds ratio = 11.3, 95% Confidence Interval 5.6 - 22.6 after adjusting for age, income and education. Most of the women with low self-perceived cervical cancer risk did not rate their HPV-related knowledge as good. However, 32 predominantly university-educated women, with low self-perceived cervical cancer risk, considered their HPV-related knowledge good.It is vital to effectively convey accurate information about these patients' cervical cancer risk, needed preventive and follow-up measures, together with the relevant

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).

To evaluate the incidence and risk factors for adjacent segment pathology (ASP) after anterior cervical spinal surgery. Fourteen patients (12 male, mean age 47.1 years) who underwent single-level cervical disk arthroplasty (CDA group) and 28 case-matched patients (24 male, mean age 53.6 years) who underwent single-level anterior cervical discectomy and fusion (ACDF group) were included. Presence of radiologic ASP (RASP) was based on observed changes in anterior osteophytes, disks, and calcification of the anterior longitudinal ligament on lateral radiographs. The mean follow-up period was 43.4 months in the CDA group and 44.6 months in the ACDF group. At final follow-up, ASP was observed in 5 (35.7%) CDA patients and 16 (57.1%) ACDF patients (p = 0.272). The interval between surgery and ASP development was 33.8 months in the CDA group and 16.3 months in the ACDF group (p = 0.046). The ASP risk factor analysis indicated postoperative cervical angle at C3-7 being more lordotic in non-ASP patients in both groups. Restoration of lordosis occurred in the CDA group regardless of the presence of ASP, but heterotopic ossification development was associated with the presence of ASP in the CDA group. And the CDA group had significantly greater clinical improvements than those in the ACDF group when ASP was present. In both CDA and ACDF patients, RASP developed, but CDA was associated with a delay in ASP development. A good clinical outcome was expected in CDA group, even when ASP developed. Restoration of cervical lordosis was an important factor in anterior cervical spine surgery.

Full Text Available A formidable threat to the health of women, cervical carcinoma can be prevented in many cases with adequate screening. The current guidelines for cervical carcinoma screening were created as joint recommendations of the American Cancer Society (ACS, the American Society for Colposcopy and Cervical Pathology (ASCCP and the American Society for Clinical Pathology (ASCP in 2012, and later accepted and promoted by the American Congress of Obstetricians and Gynecologists (ACOG. The 2012 recommendations underscore the utility of molecular testing as an adjunct to cytology screening for certain women and provide guidance to clinicians based on different risk-benefit considerations for different ages. This manuscript will review screening techniques and current recommendations for cervical cancer screening and human papilloma virus (HPV testing, as well as possible future screening strategies.

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...

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.

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.

"White Cord Syndrome" of Acute Hemiparesis After Posterior Cervical Decompression and Fusion for Chronic Cervical Stenosis.

2018-05-01

"White cord syndrome" is a very rare condition thought to be due to acute reperfusion of chronically ischemic areas of the spinal cord. Its hallmark is the presence of intramedullary hyperintense signal on T2-weighted magnetic resonance imaging sequences in a patient with unexplained neurologic deficits following spinal cord decompression surgery. The syndrome is rare and has been reported previously in 2 patients following anterior cervical decompression and fusion. We report an additional case of this complication. A 68-year-old man developed acute left-sided hemiparesis after posterior cervical decompression and fusion for cervical spondylotic myelopathy. The patient improved with high-dose steroid therapy. The rare white cord syndrome following either anterior cervical decompression and fusion or posterior cervical decompression and fusion may be due to ischemic-reperfusion injury sustained by chronically compressed parts of the spinal cord. In previous reports, patients have improved following steroid therapy and acute rehabilitation. Copyright © 2018 Elsevier Inc. All rights reserved.

Cervical spine injuries of children, though rare, have a high morbidity and mortality. The pediatric cervical spine is anatomically and biomechanically different from that of adults. Hence, the type, level and outcome of cervical spine injuries in children are different from those seen in adults. Normal developmental variants seen in children can make evaluation of the pediatric cervical spine challenging. This article reviews the epidemiology of pediatric cervical spine trauma, normal variants seen in children and specific injuries that are more common in the pediatric population. We also propose an evidence-based imaging protocol to avoid unnecessary imaging studies and minimize radiation exposure in children. (orig.)

CONCLUSION: We achieved better cervical lordotic angles at the postoperative period by implanting one-level, two-level, three-level or four-level PEEK cage filled with demineralized bone matrix. Also, the causes of cervical root and or medulla spinalis impingement were different in group1 and 2. While extruded cervical disc impingement was the first pathology in group 1, osteophyte formation was the first pathology in group 2.

Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis.

Aim: In many countries, the age-specific pattern of cervical cancer incidence is currently bipolar with peaks at for instance 45 and 65 years of age. Consequently, a large proportion of cervical cancer cases are presently diagnosed in women above the screening age. The purpose of the study...... was to determine whether this bipolar pattern in age-specific incidence of cervical cancer reflects underlying biology or can be explained by the fact that the data come from birth cohorts with different screening histories. Methods: Combination of historical data on cervical screening and population-based cancer...... incidence data from Denmark 1943–2013, Finland and Norway 1953–2013, and Sweden 1958–2013. Results: Since the implementation of screening, the incidence of cervical cancer has decreased for each successive birth cohort. All birth cohorts showed a unipolar age-specific pattern.

Full Text Available HIV-infected women are at increased risk for developing cervical cancer. Women living in resource-limited countries are especially at risk due to poor access to cervical cancer screening and treatment. We evaluated three cervical cancer screening methods to detect cervical intraepithelial neoplasia grade 2 and above (CIN 2+ in HIV-infected women in South Africa; Pap smear, visual inspection with 5% acetic acid (VIA and human papillomavirus detection (HPV.HIV-infected women aged 18-65 were recruited in Johannesburg. A cross-sectional study evaluating three screening methods for the detection of the histologically-defined gold standard CIN-2 + was performed. Women were screened for cervical abnormalities with the Digene HC2 assay (HPV, Pap smear and VIA. VIA was performed by clinic nurses, digital photographs taken and then later reviewed by specialist physicians. The sensitivity, specificity and predictive valves for CIN-2 + were calculated using maximum likelihood estimators.1,202 HIV-infected women participated, with a median age of 38 years and CD4 counts of 394 cells/mm(3. One third of women had a high grade lesion on cytology. VIA and HPV were positive in 45% and 61% of women respectively. Estimated sensitivity/specificity for HPV, Pap smear and VIA for CIN 2+ was 92%/51.4%, 75.8%/83.4% and 65.4/68.5% (nurse reading, respectively. Sensitivities were similar, and specificities appeared significantly lower for the HPV test, cytology and VIA among women with CD4 counts ≤200 cells/mm(3 as compared to CD4 counts >350 cells/mm(3.Although HPV was the most sensitive screening method for detecting CIN 2+, it was less specific than conventional cytology and VIA with digital imaging review. Screening programs may need to be individualized in context of the resources and capacity in each area.

The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years). Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%). On control examinations, there was no finding of instability or cervical kyphosis. Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

We modelled human papilloma virus (HPV) primary screening scenarios compared with Pap cytology to evaluate clinical effectiveness and projected annual costs in Germany. A Markov cohort model was built to compare the budget impact of annual Pap cytology with different 5-yearly HPV screening scenarios: (1) a positive HPV test followed by Pap cytology; (2) a positive HPV test followed by p16/Ki-67 dual-stained cytology; (3) a positive HPV test followed by colposcopy if HPV-16/18-positive or p16/Ki-67 dual-stained cytology if positive for other subtypes; (4) co-testing with HPV and Pap. Screening scenarios were based on a 10-year horizon. All HPV screening scenarios in the model were associated with fewer deaths from missed diagnosis of cervical cancer compared with Pap screening; 10-year totals n=172-344 (1.5-3 per 100,000) versus n=477 (4.1 per 100,000), respectively. Total annual costs were lower with HPV screening than Pap cytology. The projected average annual cost for HPV screening ranged from €117 million to €136 million compared with €177 million for Pap screening, representing annual savings of €41-60 million. The greatest clinical impact was achieved with primary HPV screening (with genotyping) followed by colposcopy for HPV 16/18-positive women or p16/Ki-67 dual-stained cytology for women positive for other HPV subtypes. Screening strategies including primary HPV testing for high-risk subtypes (HPV-16/18) in conjunction with p16/Ki-67 dual-stained cytology can improve the detection of cervical cancer at a lower total annual cost than conventional Pap cytology screening.

Been, Ella; Shefi, Sara; Soudack, Michalle

2017-06-01

Cervical lordosis is of great importance to posture and function. Neck pain and disability is often associated with cervical lordosis malalignment. Surgical procedures involving cervical lordosis stabilization or restoration must take into account age and gender differences in cervical lordosis architecture to avoid further complications. Therefore, the purpose of the present study was to evaluate differences in cervical lordosis between males and females from childhood to adulthood. This is a retrospective descriptive study. A total of 197 lateral cervical radiographs of patients aged 6-50 years were examined. These were divided into two age groups: the younger group (76 children aged 6-19; 48 boys and 28 girls) and the adult group (121 adults aged 20-50; 61 males and 60 females). The retrospective review of the radiographs was approved by the institutional review board. On each radiograph, six lordosis angles were measured including total cervical lordosis (FM-C7), upper (FM-C3; C1-C3) and lower (C3-C7) cervical lordosis, C1-C7 lordosis, and the angle between foramen magnum and the atlas (FM-C1). Wedging angles of each vertebral body (C3-C7) and intervertebral discs (C2-C3 to C6-C7) were also measured. Vertebral body wedging and intervertebral disc wedging were defined as the sum of the individual body or disc wedging of C3 to C7, respectively. Each cervical radiograph was classified according to four postural categories: A-lordotic, B-straight, C-double curve, and D-kyphotic. The total cervical lordosis of males and females was similar. Males had smaller upper cervical lordosis (FM-C3) and higher lower cervical lordosis (C3-C7) than females. The sum of vertebral body wedging of males and females is kyphotic (anterior height smaller than posterior height). Males had more lordotic intervertebral discs than females. Half of the adults (51%) had lordotic cervical spine, 41% had straight spine, and less than 10% had double curve or kyphotic spine. Children had

Pap smears are the most common and inexpensive screening method for cervical cancer. We analyzed micronucleus prevalence in exfoliated cervical mucosa cells, to investigate associations between increased numbers of micronuclei and risk factors for cervical cancer. Analytical cross-sectional study, at Instituto de Pesquisa em Oncologia (IPON). Exfoliated cervical cells were obtained from 101 patients between September 2004 and November 2005. Patients' ages, habits (passive or active smoking, alcoholism and numbers of sexual partners), age at first sexual intercourse, contraceptive methods used, histories of sexually transmitted diseases, use of hormone replacement therapy, numbers of pregnancies and abortions, inflammatory cytology and cervical intraepithelial neoplasia (CIN) were obtained. Cells were collected using Ayre spatulas, transferred to vials containing 0.9% saline solution for micronucleus tests and analyzed at 1000x magnification. The number of micronuclei in 1,000 epithelial cells per patient sample was counted. Comparisons between groups with active (7.9 +/- 7.8) and passive (7.2 +/- 10.6) smoking versus no smoking (3.7 +/- 5.1); with/without alcoholism (7.8 +/- 1.4 and 6.9 +/- 10.1); with/without inflammatory cytology (10.7 +/- 10.5 and 1.3 +/- 1.7); and with CIN I, II and III and no CIN (respectively 4.3 +/- 4.3, 10.6 +/- 5.3, 22.7 +/- 11.9 and 1.3 +/- 1.4) found elevated micronucleus prevalence (P < 0.05). We concluded that the prevalence of micronuclei in exfoliated uterine cervical cells was greater in patients with one or more risk factors for uterine cervical cancer than in patients without risk factors.

The magnetic resonance imaging (MRI) spectrum of acute injury to the cervical spine was illustrated in this pictorial essay. The appearance of the traumatized cord was discussed, including intramedullary hemorrhage, and the causes of spinal cord compression, such as disk herniation, epidural hematoma, fracture, dislocation and underlying spinal stenosis. The ability of MRI to directly reveal the severity of cord injury and simultaneously indicate the cause of cord compression proved particularly useful in the management of incomplete injury, for which surgical intervention may prevent further deterioration. The protocol for MRI of cervical spinal trauma included sagittal T1-weighted and T2-weighted conventional spin-echo sequences. In addition, transverse T2-weighted gradient-echo images were obtained. MRI`s ability to directly reveal the extent of cord injury was said to be a powerful tool in the management of incomplete injuries where further deterioration could be prevented by timely surgical intervention. 7 refs., 12 figs.

The purpose of our study was (1) to explain the relationship between levels of inflammatory cytokines and levels of hyaluronic acid in cervical mucus of pregnant women and (2) to investigate whether cytokines promote hyaluronic acid production by human cervical fibroblasts in vitro. The concentration of hyaluronic acid, interleukin-1beta, and interleukin-8 were measured in cervical mucus of pregnant women, and hyaluronic acid production by cytokine-treated (interleukin-1beta and interleukin-8) cultured fibroblasts was measured. Hyaluronic acid concentrations in the mucus of pregnant women with threatened premature labor were higher than in mucus of normal pregnant women (P hyaluronic acid concentrations and interleukin-1beta (P = .018) and interleukin-8 (P = .003) concentrations in cervical mucus. Cytokines (especially interleukin-8) stimulated hyaluronic acid production by cultured cervical fibroblasts. Cytokines induce hyaluronic acid production by human cervical fibroblasts, which may promote cervical ripening.

2012-02-01

The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970\\'s. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review.

Cervical cancer screening with Pap smear test is a cost-effective method. The Ministry of Health in Turkey recommends that it be performed once every five years after age 35. The purpose of this study was to determine the cervical cancer risk levels of women between 35 and 69, and the intervals they have the Pap smear test, and to investigate the relation between the two. This study was performed on 227 women aged between 35 and 69 living in Balçova District of İzmir province. Using the cervical cancer risk index program of Harvard School of Public Health, the cervical cancer risk level of 70% of the women was found below average, 22.1% average, and 7.9% above average. Only 52% of the women have had Pap smear test at least once in their lives. The percentage screening regularly in conformity with the national screening standard was 39.2%. Women in the 40-49 age group, were married, conformed significantly more (pducation and decreased with the cervical cancer risk level (pducation level, menstruation state of the women and the economic level of the family. Not having the Pap smear test in conformity with the national cervical cancer screening standard in 35-39 age group was 2.52 times more than 40-49 age group, while it was 3.26 times more in 60-69 age group (pducation level might cause not having Pap smear test. Under these circumstances, the cervical cancer risk levels should be determined and the individuals should be informed. Providing Pap smear test screening service to individuals in the target group of national screening standard, as a public service may resolve the inequalities due to age and educational differences.

Diagnosis of skeletal age in adolescents helps orthodontists select and time treatments. Currently this is done using lateral cephalometric radiographs. This study evaluates the application of the conventional method in cone-beam computer tomographic (CBCT) images to bring forth assessment of skeletal maturation in three-dimensions. Ninety-eight lateral cephalometric radiographs and CBCT scans were collected from orthodontic patients between 11 to 17 years of age over an 18-month period. CBCT scans were examined in seven sagittal slices based on cervical vertebral maturation staging (CVMS). Collected CVMS values were compared with those from corresponding lateral cephalometric radiograph. CVMS measured from CBCT and lateral cephalometric radiographs were the same on average. However, they were not consistent with each other and scored interclass correlation coefficient of 0.155 in validity test. Interoperator reliability was weak (0.581). Adaptation of cervical vertebrae maturation staging in CBCT requires further clarifications or modifications to become consistent with lateral cephalometric examinations and to become a reliable method. Alternatively, a completely new method may be developed consisting of maturational indicators or landmarks unique to CBCT imaging. Copyright © 2012. Published by Elsevier Masson SAS.

Anterior cervical discectomy and fusion (ACDF) constitutes the conventional treatment of cervical disc herniation due to degenerative disc disease (DDD). ACDF with plating presents a variety of complications postoperatively and stand-alone cages are thought to be a promising alternative. The aim of this study was firstly, to analyze prospectively collected data from a sample of patients treated with single ACDF using C-Plus self-locking stand-alone PEEK cage system, without the use of plates or screws, in order to evaluate pain levels of patients, utilizing Neck and Arm Pain scale as an expression of visual analogue scale (VAS). Secondly, we aimed to evaluate health-related quality of life, via the short-form 36 (SF-36) and Neck Disability Index (NDI). Thirty-six patients (19 male and 17 female) with mean age 49.6±7 years old who underwent successful single ACDF using self-locking stand-alone PEEK cage for symptomatic cervical DDD were selected for the study. Neck and Arm pain, as well as SF-36 and NDI were estimated preoperatively and 1, 3, 6, and 12 months postoperatively. Patients underwent preoperative and postoperative clinical, neurological and radiological evaluation. The clinical and radiological outcomes were satisfactory after a minimum 1-year follow-up. All results were statistically important (P<0.05), excluding improvement in NDI measured between 6 and 12 months. SF-36, Neck Pain, as well as Arm Pain featured gradual and constant improvement during follow-up, with best scores presenting at 12 months after surgery, while NDI reached its best at 6 months postoperatively. Generally, all scores showed improvement postoperatively during the different phases of the follow-up. Subsequently, ACDF using C-Plus cervical cage constitutes an effective method for cervical disc herniation treatment, in terms of postoperative improvement on pain levels and health-related quality of life and a safe alternative to the conventional method of treatment for cervical DDD.

In the emergency department 65 % of spinal injuries and 2-5 % of blunt force injuries involve the cervical spine. Of these injuries approximately 50 % involve C5 and/or C6 and 30 % involve C2. Older patients tend to have higher spinal injuries and younger patients tend to have lower injuries. The anatomical and development-related characteristics of the pediatric spine as well as degenerative and comorbid pathological changes of the spine in the elderly can make the radiological evaluation of spinal injuries difficult with respect to possible trauma sequelae in young and old patients. Two different North American studies have investigated clinical criteria to rule out cervical spine injuries with sufficient certainty and without using imaging. Imaging of cervical trauma should be performed when injuries cannot be clinically excluded according to evidence-based criteria. Degenerative changes and anatomical differences have to be taken into account in the evaluation of imaging of elderly and pediatric patients.

Objective Prior studies suggest an increased risk of cervical cancer among women with systemic lupus erythematosus. However, the relationship with immunosuppressive drugs is not well studied in US nationwide cohorts. We compared the risk of high-grade cervical dysplasia and cervical cancer among women with systemic lupus erythematosus who started immunosuppressive drugs versus hydroxychloroquine. Methods We identified systemic lupus erythematosus patients initiating immunosuppressive drugs or hydroxychloroquine using claims data from two US commercial health plans and Medicaid (2000-2012). We used a validated claims-based algorithm to identify high-grade cervical dysplasia or cervical cancer. To account for potential confounders, including demographic factors, comorbidities, medication use, HPV vaccination status, and health care utilization, immunosuppressive drugs and hydroxychloroquine initiators were 1:1 matched on the propensity score. We used inverse variance-weighted, fixed effect models to pool hazard ratios from the propensity score-matched Medicaid and commercial cohorts. Results We included 2451 matched pairs of immunosuppressive drugs and hydroxychloroquine new users in the commercial cohort and 7690 matched pairs in Medicaid. In the commercial cohort, there were 14 cases of cervical dysplasia or cervical cancer among immunosuppressive drugs users and five cases among hydroxychloroquine users (hazard ratio 2.47, 95% CI 0.89-6.85, hydroxychloroquine = ref). In Medicaid, there were 46 cases among immunosuppressive drugs users and 29 cases in hydroxychloroquine users (hazard ratio 1.24, 95% CI 0.78-1.98, hydroxychloroquine = ref). The pooled hazard ratio of immunosuppressive drugs was 1.40 (95% CI 0.92-2.12). Conclusion Among women with systemic lupus erythematosus, immunosuppressive drugs may be associated with a greater, albeit not statistically significant, risk of high-grade cervical dysplasia and cervical cancer compared to patients receiving

Cervical spine together with vestibular system,visual system and proprioceptive afferents plays an important role in mentaining balance. Spine damage causes distortions in transmitting informations to the brain,favoring vertigo. The authors point out the occurrence of positional vertigo on 23 patients (20 patients with cervical spondylosis and 3 patients with cervical spine injury) due to blood flow disturbance through vertebral artery. The mechano-receptors located in intervertebral disks and cervical spine muscles are activated by column movement. Changes of blood flow in the vertebral and basilar arteries are showed up by cervical X-Rays, intracranial Doppler ultrasound or angio-MRI, an audiogram marking out the degree of hearing loss or tinnitus occurence. ENT complex treatment outcomes are analyzed and balneo-physio-therapy performed in order to improve vertigo and hearing loss. Stress beside muscle overload and cervical spine injures causes alteration in the ear blood-flow circulation that leads to hearing loss, vertigo and tinnitus. It emphasies the need for collaboration between balneologist and ENT specialist in solving balance and hearing disorders with cervicogenic cause.

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

Full Text Available PURPOSE: The purpose of this study was to describe the epidemiology of cervical spine injury in the patients with cervical trauma and analyze its associated risk factors during the special heating season in North China. METHODS: This cross-sectional study investigated predictors for cervical spine injury in cervical trauma patients using retrospectively collected data of Hebei Provincial Orthopaedic Hospital from 11/2011 to 02/2012, and 11/2012 to 02/2013. Binary logistic regression analysis was used to determine risk factors for cervical fractures/dislocations or cord injury. RESULTS: A total of 106 patients were admitted into this study. Of all, 34 patients (32.1% were treated from 11/2011 to 02/2012 and 72 patients (67.9% from 11/2012 to 02/2013. The mean age was 41.9±13.3 years old; 85 patients (80.2% were male and 82 (77.4% from rural areas. Eighty patients (75.5% were caused by fall including 45 (42.5% by severe fall (>2 m. Sixty-five patients (61.3% of all suffered injuries to other body regions and 32 (30.2% got head injury. Thirty-one patients (29.2% sustained cervical cord injury with cervical fractures/dislocations. Twenty-six (83.9% of cervical cord injury patients were from rural areas and 24 (77.4% of those resulted from fall including 15 (48.4% from severe fall (>2 m. Logistic regression displayed that age (OR, 1.47; 95% CI, 1.05-2.07, head injury (OR, 5.63; 95% CI, 2.23-14.26, were risk factors for cervical cord injury and snowing (OR, 8.25; 95% CI, 2.26-30.15 was a risk factor for cervical spine injury due to severe fall (>2 m. CONCLUSIONS: The elder male patients and patients with head trauma are high-risk population for cervical cord injury. As a seasonal factor, snowing during heating season is of note a risk factor for cervical spine injury resulting from severe fall (>2 m in the patients with cervical trauma in North China.

Objectives Loss of motion following spine segment fusion results in increased strain in the adjacent motion segments. However, to date, studies on the biomechanics of the cervical spine have not assessed the role of coupled motions in the lumbar spine. Accordingly, we investigated the biomechanics of the cervical spine following cervical fusion and lumbar fusion during simulated whiplash using a whole-human finite element (FE) model to simulate coupled motions of the spine. Methods A previously validated FE model of the human body in the driver-occupant position was used to investigate cervical hyperextension injury. The cervical spine was subjected to simulated whiplash exposure in accordance with Euro NCAP (the European New Car Assessment Programme) testing using the whole human FE model. The coupled motions between the cervical spine and lumbar spine were assessed by evaluating the biomechanical effects of simulated cervical fusion and lumbar fusion. Results Peak anterior longitudinal ligament (ALL) strain ranged from 0.106 to 0.382 in a normal spine, and from 0.116 to 0.399 in a fused cervical spine. Strain increased from cranial to caudal levels. The mean strain increase in the motion segment immediately adjacent to the site of fusion from C2-C3 through C5-C6 was 26.1% and 50.8% following single- and two-level cervical fusion, respectively (p = 0.03, unpaired two-way t-test). Peak cervical strains following various lumbar-fusion procedures were 1.0% less than those seen in a healthy spine (p = 0.61, two-way ANOVA). Conclusion Cervical arthrodesis increases peak ALL strain in the adjacent motion segments. C3-4 experiences greater changes in strain than C6-7. Lumbar fusion did not have a significant effect on cervical spine strain. Cite this article: H. Huang, R. W. Nightingale, A. B. C. Dang.

Measurement of cervical motion (CM) is probably the most commonly applied functional outcome measure in assessing the status of patients with cervical pathology. In general terms, CM refers to motion of the head relative to the trunk as well as conjunct motions within the cervical spine. Multiple techniques and instruments have been used for assessing CM. These were associated with a wide variety of parameters relating to accuracy, reproducibility, and validity. Modern measurement systems enable recording, processing, and documentation of CM with a high degree of precision. Cervical motion measures provide substantial information regarding the severity of motion limitation and level of effort in cervically involved patients. They may also be used for following up performance during and after conservative or invasive interventions.

To develop recommendations for practising physicians on the advisability of screening for human papillomavirus (HPV) infection in asymptomatic women. Visual inspection, Papanicolaou testing, colposcopy or cervicography, use of HPV group-specific antigen, DNA hybridization, dot blot technique, Southern blot technique or polymerase chain reaction followed by physical or chemical therapeutic intervention. Evidence for a link between HPV infection and cervical cancer, sensitivity and specificity of HPV screening techniques, effectiveness of treatments for HPV infection, and the social and economic costs incurred by screening. MEDLINE was searched for articles published between January 1966 to June 1993 with the use of the key words "papillomavirus," "cervix neoplasms," "mass screening," "prospective studies," "prevalence," "sensitivity," "specificity," "human" and "female." Proven cost-effective screening techniques that could lead to decreased morbidity or mortality were given a high value. The evidence-based methods and values of the Canadian Task Force on the Periodic Health Examination were used. Potential benefits are to prevent cervical cancer and eliminate HPV infection. Potential harmful effects include the creation of an unnecessary burden on the health care system and the labelling of otherwise healthy people as patients with a sexually transmitted disease for which therapy is generally ineffective. Potential costs would include expense of testing, increased use of colposcopy and treatment. There is fair evidence to exclude HPV screening (beyond Papanicolaou testing for cervical cancer) in asymptomatic women (grade D recommendation). The report was reviewed by members of the task force and three external reviewers who were selected to represent different areas of expertise. These guidelines were developed and endorsed by the task force, which is funded by Health Canada and the National Health Research and Development Program. The principal author (K.J.) was

High and low dose-rate brachytherapy for cervical carcinoma

For the brachytherapy component of the r[iation treatment of cervical carcinoma, high dose rate (HDR) is slowly replacing conventional low dose rate (LDR) due primarily to r[iation safety and other physical benefits attributed to the HDR modality. Many r[iation oncologists are reluctant to make this change because of perceived r[iobiological dis[vantages of HDR. However, in clinical practice HDR appears to be as effective as LDR but with a lower risk of late complications, as demonstrated by one randomized clinical trial and two comprehensive literature and practice surveys. The reason for this appears to be that the r[iobiological dis[vantages of HDR are outweighed by the physical [vantages. (orig.)

Digital colposcopy is an emerging new technology, which can be used as adjunct to the conventional Pap test for staging of cervical cancer and it can improve the diagnostic accuracy of the test. Computer aided diagnosis (CAD) in digital colposcopy has as a goal to segment and outline abnormal areas on the cervix, one of which is an important anatomical landmark on the ectocervix - the transformation zone (TZ). In this paper we proposed a new method for estimation of the local spectrum features of cervical cancer in vivo. We used a 2D method to estimate the energy of the local frequency bands, using a geometric restriction (GR). In the current work we reported up to 12 dB difference between the local power spectral density content of the region of interest (ROI) and (ROI) C for the mid-frequency band. We devised a method to present pseudo-color visual maps of the cervical images, useful for CAD and successful ROI segmentation. (author)

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.

Static X-rays recorded at two planes from the cervical spine of 286 patients were evaluated and were compared to findings obtained from 50 probands without complaints. The patients complained about problems relating to vertebrogenic pain syndrome of the cervical spine, including vertigo of cervical origin. They were grouped by four sets of clinical symptoms (cephalgia, vertigo, locally delimited complaints and cervicobrachial syndrome). No statistically significant differences were found to exist among the groups of probands with regard to radiographic morphology, static condition nor impairment of relations. Particular reference is made in this paper to reversible function disorders and their major role among the multifactorial causes of the cervical syndrome. Indications are derived from these observations for primary X-ray examination of the cervical spine. (orig.) [de

Cervical SPECT Camera for Parathyroid Imaging

Primary hyperparathyroidism characterized by one or more enlarged parathyroid glands has become one of the most common endocrine diseases in the world affecting about 1 per 1000 in the United States. Standard treatment is highly invasive exploratory neck surgery called Parathyroidectomy. The surgery has a notable mortality rate because of the close proximity to vital structures. The move to minimally invasive parathyroidectomy is hampered by the lack of high resolution pre-surgical imaging techniques that can accurately localize the parathyroid with respect to surrounding structures. We propose to develop a dedicated ultra-high resolution (~ 1 mm) and high sensitivity (10x conventional camera) cervical scintigraphic imaging device. It will be based on a multiple pinhole-camera SPECT system comprising a novel solid state CZT detector that offers the required performance. The overall system will be configured to fit around the neck and comfortably image a patient.

Full Text Available By the example of examination of 80 children aged from 4 to 18 with cervical syndrome it is indicated, that the diagnosed abnormalities of hemodynamics in vertebrobasilar basin in patients of all age groups are connected both with bone and vascular pathology of the cervical part of the spine. The pathology has functional or congenital character. Early detection of discicirculatory vascular injuries in the cervical part of the spine in children with cervical syndrome will allow to define the therapeutic management of patients and to prolong juvenile osteochondrosis clinical behaviour.

To determine the association of pre-operative assessment of MRI findings, neurological status and symptoms with postoperative Cloward surgical outcome in cervical disc prolapse. Descriptive study. The Neurosurgery Department of Jinnah Postgraduate Medical Centre (JPMC), Karachi, from May 2008 to May 2009. Patients presenting with neck pain, brachialgia, limb weakness and spasticity were clinically examined for pre-operative neurological status of power, reflexes and sensation. The exclusion criteria were, cervical disc prolapsed patients, planned for smith-Robinson and micro-discectomy, traumatic cervical disc prolapse and cervical spondylosis. Neuroradiological investigations included cervical spine X-rays and MRI. All patients were surgically treated for cervical prolapsed intervertebral disc with anterior cervical discectomy and interbody fusion with Cloward technique. Postoperative neck immobilization was done with cervical collar for 7-8 weeks. Drain was removed on first postoperative day while check plain cervical X-rays were taken on third day. Results were analysed using chi-square test with significance at p cervical disc prolapse were C 5-6 (43.3%) and C 6-7 (23.3%); 26 (86.6%) patients had disc herniation causing thecal effacement with cord compression and 04 (13.3%) patients showed ischemia of cord. Single-level Cloward surgery done in 26 (86.3%) patients while two-level Cloward surgery performed in 04 (13.3%) only. About 83.3% patients improved and 13.3% did not while 01 patient was re-operated. No complications and mortality was related to the surgical procedure. Statistically different variables identified, related to outcome were pre-operative neurological status (p=0.001) and spinal cord involvement on MRI (p=0.001). Cloward technique for cervical disc prolase was simple and safe surgical procedure with favourable results and few complications; 100% fusion occurred after Cloward surgery, even without instrumentation. Outcome was significantly

Full Text Available Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years. Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%. On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

Cervical cancer prevention should be provided as part of primary healthcare services for HIV-infected women but conventional screening programs are difficult to implement in low-resource settings. Here, we evaluate the efficacy among HIV-infected women of a simpler, screen-and-treat strategy in which all women with a positive screening test are treated with cryotherapy. We conducted a randomized clinical trial of two screen-and-treat strategies among 6555 women in Cape Town, South Africa, among whom 956 were HIV-positive. Women were randomized to screen-and-treat utilizing either human papillomavirus DNA testing or visual inspection with acetic acid as the screening method or to a control group. Women were followed for up to 36 months after randomization with colposcopy and biopsy to determine the study endpoint of cervical intraepithelial neoplasia grade 2 or higher. In the control group, HIV-positive women had higher rates of cervical intraepithelial neoplasia grade 2 or higher detected by 36 months (14.9%) than HIV-negative women (4.6%) (P = 0.0006). Screen-and-treat utilizing human papillomavirus DNA testing significantly reduced cervical intraepithelial neoplasia grade 2 or higher through 36 months in both HIV-positive (relative risk = 0.20, 95% confidence interval 0.06-0.69) and HIV-negative women (relative risk = 0.31, 95% confidence interval 0.20-0.50). Reductions in the visual inspection with acetic acid-and-treat group were less marked. Complications of cryotherapy were mostly minor and did not differ in frequency between HIV-positive and HIV-negative women. Screen-and-treat using human papillomavirus testing is a simple and effective method to reduce high-grade cervical cancer precursors in HIV-infected women.

Nowadays, anterior cervical artificial disc replacement (ACDR) has achieved favorable outcomes in treatment for patients with single-level cervical spondylosis. However, It is still controversial that whether or not it will become a potent therapeutic alternation in treating 2 contiguous levels cervical spondylosis compared with anterior cervical decompression and fusion (ACDF). Therefore, we conducted a systematic review and meta-analysis to compare the efficacy and safety of ACDR and ACDF in patients with 2 contiguous levels cervical spondylosis. According to the computer-based online search, PubMed, Embase, Web of Science, and Cochrane Library for articles published before July 1, 2017 were searched. The following outcome measures were extracted: neck disability index (NDI), visual analog scale (VAS) neck, VAS arm, Short Form (SF)-12 mental component summary (MCS), SF-12 physical component summary (PCS), overall clinical success (OCS), patient satisfaction (PS), device-related adverse event (DRAE), subsequent surgical intervention (SSI), neurological deterioration (ND), and adjacent segment degeneration (ASD). Methodological quality was evaluated independently by 2 reviewers using the Furlan for randomized controlled trial (RCT) and MINORS scale for clinical controlled trials (CCT). The chi-squared test and Higgin I test were used to evaluate the heterogeneity. A P bi-level cervical spondylosis, ACDR appears to provide superior clinical effectiveness and safety effects than ACDF. In the future, more high-quality RCTs are warranted to enhance this conclusion.
