To verify the usefulness of a fluoroscopy guided cervical interlaminar epidural steroid injection (CIESI) in patients with neck pain and cervical radiculopathy and to evaluate outcome predictors. We retrospectively analyzed 91 patients from July 2004 to June 2005 in whom CIESI was initially performed for neck pain and cervical radiculopathy. Therapeutic effects were evaluated 2 weeks after the administration of CIESI, and CIESI effectiveness was graded using a five-point scale, namely, whether the pain had disappeared, was much improved, slightly improved, the same, or aggravated. We also used a visual analog scale (VAS) for the clinical evaluation. According to documentation and follow-up charts, we categorized treatments as effective or ineffective. Possible outcome predictors, namely, diagnosis (spinal stenosis vs herniated disc), primary symptoms (neck pain vs radiculopathy vs both), age, gender, and duration of pain (more or less than 6 months) were also analyzed. Fisher's exact test, the chi-square test, and multiple logistic regression analysis were used for the statistical analysis. After their medical records had been reviewed, 76 patients were included in this study. Inclusion criteria were: the availability of a cross-sectional image, such as a CT scan or an MR image, and a follow-up record after injection. The medical records of 76 patients (male:female = 41: 35) of mean age 53.1 years (range 32 years to 82 years) were reviewed. Two weeks after injection, 55 patients (72.4%) had experienced effective pain relief. Patients with herniated discs had significantly better results than patients with spinal stenosis (86.1% vs 60.0%) (P < 0.05). Other non-significant predictors of an improved outcome included: a symptom duration of <6 months, a young age, and the presence of cervical radiculopathy. Multiple regression analysis showed that the only factor that was significantly associated with outcome was the cause of the pain, i.e., herniated disc or spinal

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)

Full Text Available Background: Treatment effectiveness and clinical outcome of patients with cervical carcinoma FIGO stage IA1 and IA2 are analyzed in three different time period at the Department of Obstetrics and Gynecology Rijeka, Croatia. Method: Retrospective analysis of the hospital chart of all cervical cancer patients between 1991 and 2005 was conducted with five-year follow up. Results: Data on cervical cancer distribution by stage and five-year survival are presented. Separately analyzed age, histology type and treatment modalities in stage FIGO IA1 and IA2 during three consecutive five-year periods are presented. Conclusions: Conservative surgical approach – conization alone in stage IA1 of the squamous cell car- cinoma is reasonable and safe treatment option for reproductive active women. During observed periods conization became the most used surgical technique applied in almost two third of FIGO IA1 cervical cancer patients. Lymph vascular space invasion in stage IA1 lead to adjunct pelvic lymphadenectomy with unclear clinical benefit. In cervical cancer patients stage IA2 simple hysterectomy and pelvic lymphadenectomy could be accepted as a standard treatment. In these patients further studies are recommended to evaluate other less radical surgical techniques – simple and radical trachelectomy with or without pelvic lymphadenectomy. Radical hysterectomy in both stages IA1 and IA2, based on personal experience and literature data represents a surgical overtreatment and should be abandoned.

Introduction of human papillomavirus (HPV) vaccination programs raises some important questions about the future organization of cervical screening programs. Two studies - from NZ and Canada - have addressed the question of what combination of vaccination and screening strategies might be most cost......-effective in preventing cervical cancer. Both studies indicate that some modifications to existing screening programs may be desirable as immunized females enter these programs. Variables in HPV vaccination that are likely to be particularly important for determining the future cost-effectiveness of cervical screening...... programs include: vaccine uptake rate, compliance with full doses, timely completion of doses, duration of protection, male vaccination and HPV infection rate. If value for money is to be achieved, it is important that the appropriate data are collected so that policy makers can consider the combined...

To design and implement a case study on the cervical cancer screening program in Botswana to teach public and global health competencies to undergraduate nursing students. The case study was developed following a review of the literature on the epidemiology and health policies of cervical cancer in Botswana, and an interview with an obstetrician/gynecologist engaged in both clinical practice and research in Botswana. The case study has been implemented over seven semesters to students enrolled in the Nursing in the Community course at the University of Pennsylvania. Approximately 75-100 students are enrolled each semester. Student's perceptions of epidemiologic skills gained and group functioning. Students responded to an open-ended question about lessons learned and offered suggestions to improve the learning experience. Faculty assessment of student deliverables demonstrated that students achieved the learning objectives and mastered necessary competencies. More than 70% (n = 69) of the students indicated that they acquired relevant skills at greater than a satisfactory level. Generally, students had great experiences working in groups measured across five dimensions: engagement/contribution, creativity/resilience, on task/works independently, social interaction/communication, and preparedness. However, isolated cases of poor group functioning were reported for engagement/contribution, and creativity/resilience. The case study, which has been revised with respect to length, content and group processes, has been valuable in educating undergraduate nursing students in a more engaging way that mimics real life public health nursing scenarios. Students achieved both public and global health competencies through participation in the case study. © 2018 Wiley Periodicals, Inc.

AIM: To determine if the use of request guidelines can achieve a sustained reduction in the number of radiographic examinations of the cervical spine, lumbar spine and knee joints performed for general practitioners (GPs). METHODS: GPs referring to three community hospitals and a district general hospital were circulated with referral guidelines for radiography of the cervical spine, lumbar spine and knee, and all requests for these three examinations were checked. Requests that did not fit the guidelines were returned to the GP with an explanatory letter and a further copy of the guidelines. Where applicable, a large-joint replacement algorithm was also enclosed. If the GP maintained the opinion that the examination was indicated, she or he had the option of supplying further justifying information in writing or speaking to a consultant radiologist. RESULTS: Overall the number of radiographic examinations fell by 68% in the first year, achieving a 79% reduction in the second year. For knees, lumbar spine and cervical spine radiographs the total reductions were 77%, 78% and 86%, respectively. CONCLUSION: The use of referral guidelines, reinforced by request checking and clinical management algorithms, can produce a dramatic and sustained reduction in the number of radiographs of the cervical spine, lumbar spine and knees performed for GPs

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

Purpose: Human papillomavirus is a dominant cause of cervical dysplasia with possible transition to cervical cancer. The main purpose of the study was to make a qualified forecast of the potential of vaccination using a bivalent vaccine on the incidence of cervical dysplasia and cervical cancer as well as disease-related mortality in the Slovak Republic. Methods: The method of evaluation was the use of the Markov model that is strictly based on either epidemiological data from official institutions such as the National Oncology Register of the Slovak Republic, Statistic Office of the Slovak Republic, or the data from health insurance companies and the opinion of the experts´ panel of the Society of Gynaecology and Obstetrics. Results: Results obtained by modelling suggest that the introduction of HPV vaccination into the national immunization programme would result in a reduction of at least 84 deaths of women during the monitored period. Every cervical cancer death averted means 31 life years saved on average. Depending on the vaccination coverage in the cohort, HPV vaccination would cause a reduction of registered cervical dysplasia by 26,900 to 131,808 cases, a reduction of registered carcinoma in situ by 1,371 to 6,714 cases, and a decrease of registered invasive cervical carcinoma by 1,645 to 8,058 cases. Conclusion: The results of the analysis confirmed that HPV vaccination in 12-year old girls has the potential to significantly reduce both the incidence of cervical dysplasia and cervical cancer and mortality due to cervical cancer, whereby this form of primary intervention is also cost-effective. Vaccination also enhances the effect of standard secondary prevention realized by age dependant screening. (author)

The objective of this study was to determine whether cervicitis in dairy cows is an independent disease or occurs concomitantly with inflammation of the uterus, and to clarify possible effects of cervicitis on reproductive performance. Dairy cows (n = 416) from 33 dairy farms were examined by rectal palpation and vaginoscopy between 42 and 50 days postpartum. Inclusion criteria for this study were absence of abnormal vaginal discharge and abnormalities of the uterus (fluctuation) at rectal palpation. Cervicitis was diagnosed when the second cervical fold was swollen and prolapsed with (C2) or without (C1) reddening. Cytobrush samples from the uterus (n = 370) and the cervix (n = 402) were collected, and the percentage of neutrophils in the uterus (PMNU) and the cervix as indicators of inflammation (threshold: ≥5%) was determined. In addition, endometrial biopsies for histology were collected, 300 of which were suitable for evaluation. Cervicitis (C1/C2) was diagnosed in 253 of 416 (60.8%) of cows. Of these, the prolapsed cervical mucosa was hyperemic (C2) in 29.1% of cases. Of 370 available uterine cytology samples, 221 cows had a clinical cervicitis; however, 170 (76.9%) had PMNU less than 5%. Of 300 uterine histologic examinations, 82 (27.3%) did not reveal any abnormalities; the remaining cows either had uterine inflammation and/or degenerative uterine changes such as endometriosis and angiosclerosis. Furthermore, of 300 biopsied animals, 184 revealed a cervicitis (C1/C2); however, 30.4% of these animals had no histopathologic uterine findings. For further analysis, only animals either without histopathologic findings and normal uterine cytology or with solely endometritis (defined as PMNU ≥ 5% and/or positive histopathology of the uterine tissue) were evaluated (n = 157). Of these, 95 cows had cervicitis. Unexpectedly, 63 of 95 (66.3%) cows had cervicitis without endometritis. With regard to reproductive performance, days to first service were

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

Cervical cancer is one of the most common gynecologic cancers. The role of apolipoprotein B mRNA-editing catalytic polypeptide-like protein-3G (APCBEC-3G) in cervical cancer has yet to be elucidated. This study intends to explore the effect of APCBEC-3G on cervical cancer cell proliferation and invasion. In vitro, the cervical cancer cell line Hela was transfected by APCBEC-3G plasmid. The mRNA and protein expression levels of APCBEC-3G were detected by Real-time PCR and Western blot, respectively. Cervical cancer cell proliferation was determined by MTT. Transwell assay was applied to measure the effect of APCBEC-3G on cell invasion. APCBEC-3G mRNA and protein increased significantly after transfection (P3G serves as a suppressor of cervical cancer cell proliferation and invasion. Our research provides theoretical basis for further investigation APOBEC-3G effect in cervical cancer occurrence and development.

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

Effects of irradiation for cervical cancer on subsequent breast cancer

Previous research suggests that cervical cancer patients have a lower risk of breast cancer than women in the general population. Possible explanations include opposing risk factors for cervical cancer and breast cancer, the effect of irradiation used to treat cervical cancer, or both. The purpose of this study was to explore the relationship between irradiation for cervical cancer and the subsequent development of breast cancer. There was no statistically significant relationship between radiation to the ovarian area and the risk of breast cancer in this study. However, the results were consistent with a 19% reduction in risk for women irradiated for cervical cancer when compared to nonirradiated women. In a dose-response analysis, there was a nonsignificant trend of decreased risk of breast cancer with increased radiation up to 1800 rad. There was no consistent pattern for higher doses. The trend, although nonsignificant, differed by age. Women <60 years of age at irradiation were generally at a lower risk of breast cancer than nonirradiated women. Women over 59 years were at an increased risk. There are some potentially important findings from this study which might influence medical care. These should be examined in the larger International Radiation Study

The effectiveness of intralesional sclerotherapy of lymphangiomas and ranulas with OK-432 (Picibanil) has been proved in several clinical studies. The aim of our study was to review the effectiveness of sclerotherapy of benign cervical cysts with Picibanil as an alternative method to surgical excision. Between March 2002 and March 2006, a prospective observational study was carried out to assess the effects of Picibanil on cervical cysts. Between 2002 and 2006 we treated 14 patients having cervical cysts through intralesional application of Picibanil with a dose of 0.01 mg/ml. So far we used Picibanil with 13 patients achieving a high success rate. In eight cases we observed, both clinically and ultrasonographically, a nearly complete regression, and a complete regression of the cysts in three cases. In two cases the cysts atrophied. In these cases only residual findings could be observed. In one case we extirpated the remaining cyst. If there is no clear reaction of the cyst to the treatment, an excision is indicated 6 weeks after the injections to gain meaningful histological examination. No significant complication after sclerotherapy with Picibanil was observed. According to our results the application of OK-432 (Picibanil) is a safe and effective primary method for sclerotherapy of benign cervical cysts which can replace surgical extirpation in special cases. However, the risk of malign diseases has to be excluded before the commencement of the Picibanil treatment.

Premature rupture of membranes is a normal occurrence of labor and can occur before or after the onset of contractions. The clinical factors associated with premature rupture of membranes include: low socioeconomic status, low body mass index, prior preterm pregnancies, smoking, sexually transmitted infections and urinary tract, conization, cervical cerclage and amniocentesis. To evaluate whether prolonged release of the vaginal insert of PGE2 is superior to dinoprostone gel to achieve cervical ripening in patients with term pregnancy that occur with premature rupture of membranes. Randomized clinical trial in the surgical unit of play in a period of 6 months, with an estimated sample of 50 patients was randomized by block table. After assessment confirming rupture of membranes, Bishop Score and meeting inclusion criteria, group A was applied PGE2 intracervical gel 0.5 mg with a maximum of 3 doses, every 6 hours. Group B was administered at vaginal insert of PGE2 single dose for 24 hours, the patient was left to sleep 30 minutes cardio toco-monitoring chart for at least 2 hours after application. The average time to maturity was 310.59 minutes with a standard deviation of 198.7 and concluded that there was no significant difference between the onset of uterine activity and the onset of labor among the prolonged release dinoprostone and alternatives such as the gel cervical for cervical ripening. Either this is a good choice to ripen the cervix in patients with term pregnancy and premature rupture of membranes.

Purpose: To compare rigosertib versus cisplatin as an effective radiosensitizing agent for cervical malignancies. Methods and Materials: Rigosertib and cisplatin were tested in cervical cancer cell lines, HeLa and C33A. A 24-hour incubation with rigosertib and cisplatin, before irradiation (2-8 Gy), was used for clonogenic survival assays. Cell cycle analysis (propidium iodide staining) and DNA damage (γ-H2AX expression) were evaluated by fluorescence-activated cell sorter cytometry. Rigosertib was also tested in vivo in tumor growth experiments on cervical cancer xenografts. Results: Rigosertib was demonstrated to induce a G 2 /M block in cancer cells. Survival curve comparison revealed a dose modification factor, as index of radiosensitization effect, of 1.1-1.3 for cisplatin and 1.4-2.2 for rigosertib. With 6-Gy irradiation, an increase in DNA damage of 15%-25% was achieved in both HeLa and C33A cells with cisplatin pretreatment, and a 71-108% increase with rigosertib pretreatment. In vivo tumor growth studies demonstrated higher performance of rigosertib when compared with cisplatin, with 53% longer tumor growth delay. Conclusions: Rigosertib was more effective than cisplatin when combined with radiation and caused minimal toxicity. These data support the need for clinical trials with rigosertib in combination therapy for patients with cervical carcinoma

To assess the effectiveness of elective history-indicated cervical cerclage according to obstetrical history. We analyzed pregnancy outcome of a retrospective cohort of women who have had history-indicated McDonald's cerclage. Principal outcome was gestational age (GA) at delivery. Between January 2003 and December 2013, 205 women were included. We analyzed population in two risk groups: 1- Low-risk (≤2 prior preterm birth (PTB)/second trimester loss (STL), or prior success of cerclage), 2- High risk (≥3 prior PTB/STL, or prior failure of cerclage). In the high-risk group, there was a higher frequency of deliveries before 37 weeks (47.5% vs. 24.5%, P=0.001, OR=2.79, 95% CI [1.49-5.23]). Fifty percent of women (n=6/12) delivered before 37 weeks in case of three or more prior PTB/STL, and 51% (n=24/47) in case of prior failure of cervical cerclage. Elective cervical cerclage may be indicated for women with≤2 prior PTB/STL, or prior successful cerclage. For women with≥3 prior PTB/STL, trachelorraphy or cervico-isthmic cerclage could be possible alternatives to cervical cerclage. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Full Text Available Abstract Background Human papillomavirus (HPV infection has been shown to be a major risk factor for cervical cancer. Vaccines against HPV-16 and HPV-18 are highly effective in preventing type-specific HPV infections and related cervical lesions. There is, however, limited data available describing the health and economic impacts of HPV vaccination in Taiwan. The objective of this study was to assess the cost-effectiveness of prophylactic HPV vaccination for the prevention of cervical cancer in Taiwan. Methods We developed a Markov model to compare the health and economic outcomes of vaccinating preadolescent girls (at the age of 12 years for the prevention of cervical cancer with current practice, including cervical cytological screening. Data were synthesized from published papers or reports, and whenever possible, those specific to Taiwan were used. Sensitivity analyses were performed to account for important uncertainties and different vaccination scenarios. Results Under the assumption that the HPV vaccine could provide lifelong protection, the massive vaccination among preadolescent girls in Taiwan would lead to reduction in 73.3% of the total incident cervical cancer cases and would result in a life expectancy gain of 4.9 days or 8.7 quality-adjusted life days at a cost of US$324 as compared to the current practice. The incremental cost-effectiveness ratio (ICER was US$23,939 per life year gained or US$13,674 per quality-adjusted life year (QALY gained given the discount rate of 3%. Sensitivity analyses showed that this ICER would remain below US$30,000 per QALY under most conditions, even when vaccine efficacy was suboptimal or when vaccine-induced immunity required booster shots every 13 years. Conclusions Although gains in life expectancy may be modest at the individual level, the results indicate that prophylactic HPV vaccination of preadolescent girls in Taiwan would result in substantial population benefits with a favorable cost-effectiveness

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.

Hydronephrosis is frequently encountered in advanced stage cervical cancers, and may be associated with mortality. In the present study, we aimed to demonstrate the effect of hydronephrosis on survival in patients with inoperable advanced stage cervical cancer. The study data were acquired by retrospective analysis of the patient records belonging to 165 women with FIGO (International Federation of Gynecology and Obstetrics) stage-IIIB or more advanced cervical cancer, which were not surgical candidates. Parameters including patient age, pathological diagnosis, disease stage, pelvic sidewall extension, presence of hydronephrosis and administration of chemoradiation were analyzed. Further, the effects of these variables on survival were assessed. P values less than 0.05 were considered statistically significant. The distribution of the study patients according to disease stage was as follows: 131 (79.4%) had stage-IIIB, 18 (10.9%) had stage-IVB and 16 (% 9.7) patients had stage-IVA disease. Hydronephrosis was not evident in 91 (55.2%) of these patients, whereas 41 (24.8%) had unilateral and 33 (20%) patients had bilateral hydronephrosis. When compared to mean survival in patients who did not have hydronephrosis, survival was significantly shortened in patients who had bilateral and unilateral hydronephrosis (phydronephrosis (p>0.05). Although patient age, pathological type, pelvic involvement, and chemotherapy treatment rates were similar (p>0.05), radiotherapy requirement rate and disease stage were significantly different among the study groups (pHydronephrosis was found to be a significant predictor of poor survival in patients with advanced stage cervical cancer, irrespective of unilateral or bilateral involvement.While waiting for future studies with larger sample sizes, we believe that the FIGO stages in advanced cervical cancer could further be stratified into subgroups according to presence or absence of hydronephrosis.

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

Aberrant activation of the Wnt/β-catenin signaling pathway is common in human cervical cancers and has great potential therapeutic value. We show that tigecycline, a FDA-approved antibiotic drug, targets cervical squamous cell carcinoma through inhibiting Wnt/β-catenin signaling pathway. Tigecycline is effective in inducing apoptosis, inhibiting proliferation and anchorage-independent colony formation of Hela cells. The inhibitory effects of tigecycline are further enhanced upon combination with paclitaxel, a most commonly used chemotherapeutic drug for cervical cancer. In a cervical xenograft model, tigecycline inhibits tumor growth as a single agent and its combination with paclitaxel significantly inhibits more tumor growth throughout the duration of treatment. We further show that tigecycline decreases level of both cytoplasmic and nuclear β-catenin and suppressed Wnt/β-catenin-mediated transcription through increasing levels of Axin 1 in Hela cells. In addition, stabilization or overexpression of β-catenin using pharmacological and genetic approaches abolished the effects of tigecycline in inhibiting proliferation and inducing apoptosis of Hela cells. Our study suggests that tigecycline is a useful addition to the treatment armamentarium for cervical cancer and targeting Wnt/β-catenin represents a potential therapeutic strategy in cervical cancer. - Highlights: • We repurposed the antibiotic drug tigecycline for cervical cancer treatment. • Tigecycline is effectively against cervical cancer cells in vitro and in vivo. • Combination of tigecycline and paclitaxel is synergistic in targeting Hela cells. • Tigecycline acts on Hela cells through inhibiting Wnt/β-catenin signaling.

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.

The vaginal smear specimens of the patients who received operative therapy, irradiation or chemotherapy for cervical carcinoma were examined. Long-term follow-up vaginal cytology following treatment of cervical carcinoma is effective for the detection of local recurrence in an early stage. Serial cytology is also useful in evaluation of the effects of irradiation and chemotherapy for cervical carcinoma. Radiosensitive and prognostic significance of vaginal smears before and after radiation therapy was discussed. (author)

Patients with cervical spondylosis myelopathy (CSM) and complicated with hypertension are often experiencing a blood pressure decrease after taking cervical decompressive surgery in clinical observations, but how this blood pressure reduction is associated with the surgery, which cut cervical sympathetic nervous, has never been rigorously assessed. Thus, the purpose of this study is to investigate the effect of cervical decompressive surgery on blood pressure among CSM patients with hypertension. The study will be a time series cohort study. Fifty eligible patients will be selected consecutively from the Peking University First Hospital. Two 24-h ambulatory blood pressure measurement (ABPM) will be taken before the surgery, apart by at least 3 days. The patients will be followed up for another two ABPMs at 1 and 3 months after the surgery. We will recruit subjects with cervical spondylosis myelopathy meeting operation indications and scheduled for receiving cervical decompressive surgery, aged 18-84 years, have a history of hypertension or office systolic blood pressure ≥140 mmHg on initial screening, and willing to participate in the study and provide informed consent. Exclusion criteria includes a history of known secondary hypertension, visual analogue scale (VAS) score ≥4, and unable to comply with study due to severe psychosis. The change in systolic ABPs over the four times will be analyzed to observe the overall pattern of the blood pressure change in relation to the surgery, but the primary analysis will be the comparison of systolic ABP between the 2(nd) and 3(rd), 4(th) measurements (before and after the surgery). We will also calculate the regression-to-the-mean adjusted changes in systolic ABP as sensitivity analysis. Secondary endpoints are the changes in 24 h ABPM diastolic blood pressure, blood pressure control status, the use and dose adjustment of antihypertensive medication, and the incidence of operative complications.

Cytology-based screening has reduced cervical cancer mortality in countries able to implement, sustain and financially support organized programs that achieve broad coverage. These ongoing secondary prevention efforts considerably complicate the question of whether vaccination against Human Papillomavirus (HPV) types -16 and 18 should be introduced. Policy questions focus primarily on the target ages of vaccination, appropriate ages for a temporary “catch-up” program, possible revisions in screening policies to optimize synergies with vaccination, including the increased used of HPV DNA testing, and the inclusion of boys in the vaccination program. Decision-analytic models are increasingly being developed to simulate disease burden and interventions in different settings in order to evaluate the benefits and cost-effectiveness of primary and secondary interventions for informed decision-making. This article is a focused review on existing mathematical models that have been used to evaluate HPV vaccination in the context of developed countries with existing screening programs. Despite variations in model assumptions and uncertainty in existing data, pre-adolescent vaccination of girls is consistently found to be attractive in the context of current screening practices, provided there is complete and lifelong vaccine protection and widespread vaccination coverage. Questions related to catch-up vaccination programs, potential benefits of other non-cervical cancer outcomes and inclusion of boys are subject to far more uncertainty, and results from these analyses have reached conflicting conclusions. Most analyses find that some catch-up vaccination is warranted but becomes increasingly unattractive as the catch-up age is extended, and vaccination of boys is unlikely to be cost-effective if reasonable levels of coverage are achieved in girls or coverage among girls can be improved. The objective of the review is to highlight points of consensus and qualitative

Women with polycystic ovary syndrome (PCOS) have increased risk of preterm delivery. Shortening of the cervix is a sign of preterm delivery. This study aimed to investigate potential effect of metformin on cervical length and whether androgen levels correlate with cervical length in PCOS pregnancies. This was a sub-study of a randomized, placebo-controlled, multicenter study (The PregMet study) performed at 11 secondary or tertiary centers from 2005 to 2009. Two-hundred sixty-one pregnancies of 245 women with PCOS, age 18-42 years participated. Participants were randomly assigned to metformin or placebo from first trimester to delivery. We compared cervical length and androgen levels in metformin and placebo groups at gestational weeks 19 and 32. We also explored whether cervical length correlated with androgen levels. We found no difference in cervical length between the metformin and the placebo groups at gestational week 19 and 32. Dehydroepiandrosterone (DHEAS) tended to be higher in the metformin group. There were no correlations between androgens and cervical length at week 19. At gestational week 32, androstenedione (P = .02) and DHEAS (P = .03) showed a trend toward negative correlation to cervical length. High androstenedione level correlated with shortening of cervical length from week 19 to 32 when adjusted for confounders (P = .003). T (P = .03), DHEAS (P = .02), and free testosterone index (P = .03) showed a similar trend. Metformin in pregnancy did not affect cervical length in women with PCOS. High maternal androgen levels correlated with cervical shortening from the second to the third trimester of pregnancy, as a sign of cervical ripening.

The advantages and disadvantages of titanium mesh cages (TMCs) assisted by anterior cervical plates (ACPs) for interbody fusion following cervical corpectomy were investigated. Between January 2002 and September 2006, 17 patients with cervical radiculomyelopathy caused by metastasis-induced pathologic fractures were selected for anterior corpectomy. TMCs were inserted into the post-corpectomy defect and stabilized by placement of ACPs filled with Triosite. Post-operative plain X-ray films indicated maintenance of spinal stability. No ceramic, donor site or surgery-related complications were observed. True trabeculation was observed in axial and reconstructive CT scans in all surviving patients one year after surgery. Neurological recovery, pain control, and good quality of life were achieved. Short hospital stays, minimal blood loss, short operation times and brief periods of bed confinement were also observed. We conclude that a TMC assisted by an ACP is safe and effective for interbody fusion following cervical corpectomy for pathological fractures resulting from cervical vertebral metastases.

To observe the effects of two different therapies on patients whose cervical function were restricted due to cervical spondylotic radiculopathy. Form April 2008 to October 2009, 71 cases with cervical spondylotic radiculopathy were divided into group A (36 cases) and group B (35 cases). Among them, 22 cases were male and 49 cases were female, ranging in age form 45 to 65 years with an average of 52.27 years, course of disease was from 3 days to 5 years. The patients in group A were treated with rotation-traction manipulation, neck pain particles and cervical rehabilitation exercises; and the patients in group B were treated with cervical traction, Diclofenac sodium sustained release tablets and wearing neck collar. Theapeutic time was two weeks. The cervical anteflexion, extension, left and right lateral bending, left and right rotative activity were measured by helmet-style activities instrument before and after treatment (at the 1, 3, 5, 7, 9, 11, 13 days and 1 month after treatment respectively). There were no difference between two groups in cervical activity in all directions before treatment (P > 0.05). Compared with the beginning, cervical anteflexion and extension showed significant difference at the 5th day after treatment in group A (P cervical anteflexion showed significant difference at the 13th day after treatment (P 0.05); cervical extension showed significant difference at the 7th day after treatment compared with the beginning (P cervical anteflexion, left and right lateral bending, left and right rotative activity showed significant difference at the 1 month after treatment (P pain particles and cervical rehabilitation exercises in treating cervicalspondylotic radiculopathy have quick effect to improve the activities of cervical anteflexion, extension, left lateral bending, and have durable effect to improve the activities of cervical spine in all directions.

With the availability of a low-cost HPV DNA test that can be administered by either a healthcare provider or a woman herself, programme planners require information on the costs and cost-effectiveness of implementing cervical cancer screening programmes in low-resource settings under different models of healthcare delivery. Using data from the START-UP demonstration project and a micro-costing approach, we estimated the health and economic impact of once-in-a-lifetime HPV self-collection campaign relative to clinic-based provider-collection of HPV specimens in Uganda. We used an individual-based Monte Carlo simulation model of the natural history of HPV and cervical cancer to estimate lifetime health and economic outcomes associated with screening with HPV DNA testing once in a lifetime (clinic-based provider-collection vs a self-collection campaign). Test performance and cost data were obtained from the START-UP demonstration project using a micro-costing approach. Model outcomes included lifetime risk of cervical cancer, total lifetime costs (in 2011 international dollars [I$]), and life expectancy. Cost-effectiveness ratios were expressed using incremental cost-effectiveness ratios (ICERs). When both strategies achieved 75% population coverage, ICERs were below Uganda's per capita GDP (self-collection: I$80 per year of life saved [YLS]; provider-collection: I$120 per YLS). When the self-collection campaign achieved coverage gains of 15-20%, it was more effective than provider-collection, and had a lower ICER unless coverage with both strategies was 50% or less. Findings were sensitive to cryotherapy compliance among screen-positive women and relative HPV test performance. The primary limitation of this analysis is that self-collection costs are based on a hypothetical campaign but are based on unit costs from Uganda. Once-in-a-lifetime screening with HPV self-collection may be very cost-effective and reduce cervical cancer risk by > 20% if coverage is high

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.

The authors' aim was to evaluate the effect of balance training on cervical joint position sense in people with subclinical neck pain. Thirty-four participants were randomly assigned to balance training or to stay active. Sensorimotor function was determined before and after 5 weeks of training by assessing the ability to reproduce the neutral head position and a predefined rotated head position. After balance training, the intervention group showed improved joint repositioning accuracy and decreased pain whereas no effects were observed in the control group. A weak correlation was identified between reduced neck pain intensity and improved joint repositioning. The present data demonstrate that balance training can effectively improve cervical sensorimotor function and decrease neck pain intensity.

Full Text Available AbstractBackground and Aim: Using cervical collars is one of the treatment methods for releaving cervical pain. The effect of limb orthotics on proprioception and postural stability has been suggested. There is not sufficient studies about the effect of cervical collars on static and dynamic stability, and the effect of soft and hard collars have not been compared with one another. The objective of this study is investigating and comparing the immediate effect of soft and hard cervical collars on static postural stability in healthy young subjects. Methods & Materials: In standing position on firm surface with closed eyes, both soft and hard collars decreased the stability and there was not any significant difference among collars. In standing positions on soft surface with closed and opened eyes, using none of the soft and hard collars did not change the stability. This quasi experimental study through repeated measure method has been conducted on 65 healthy young male and female college students. Static stability was evaluated by modified Clinical Test for Sensory Interaction and Balance (CTSIB in conditions without collar and by soft and hard cervical collars and were compared between the conditions. Results: Conclusion: Our results suggest that in static conditions, without vision, both collars decrease the stability in healthy young subjects. So considering the evaluation of stability and prevention of balance disturbance during the collar prescription seems to be necessary.

To assess the health and economic outcomes of various screening and vaccination strategies for cervical cancer prevention. Cost-effectiveness analysis from a societal perspective. Thailand. Females aged 9 years and older. Using a mathematical model of human papillomavirus (HPV) infection and cervical cancer, calibrated to epidemiological data from Thailand, we estimated the cost-effectiveness of pre-adolescent HPV vaccination, screening [visual inspection with acetic acid (VIA), HPV DNA testing, and cytology] between one and five times per lifetime in adulthood, and combined pre-adolescent vaccination and screening. Vaccine efficacy, coverage, cost, and screening frequency were varied in sensitivity analyses. Incremental cost-effectiveness ratios, expressed as cost per year of life saved (YLS). Assuming lifelong efficacy and 80% coverage, pre-adolescent HPV vaccination alone was projected to reduce the lifetime risk of cervical cancer by 55%, which was greater than any strategy of screening alone. When cost per vaccinated girl was I$10 (approximately $2 per dose) or less, HPV vaccination alone was cost saving. Pre-adolescent vaccination and HPV DNA testing five times per lifetime, starting at age 35 years, reduced the lifetime cervical cancer risk by 70%, and had a cost-effectiveness ratio less than Thailand's GDP per capita (I$8100), provided the cost per vaccinated girl was I$200 or less. Low cost pre-adolescent HPV vaccination followed by HPV screening five times per lifetime is an efficient strategy for Thailand. Costs may need to be lower, however, for this strategy to be affordable. If vaccination is not feasible, HPV DNA testing five times per lifetime is efficient. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

To determine if a particulate steroid which has a risk for embolic infarct would be more effective than a non-particulate steroid for transforaminal epidural steroid injection (TFESI). The purpose of this study was (1) to compare the effect of cervical TFESI using particulate (e.g., triamcinolone) and non-particulate (e.g., dexamethasone) steroids and (2) to evaluate the effectiveness of cervical TFESI in general. From January 2006 to August 2008, 159 consecutive patients [male:female (M:F) 89:70; mean age 53 years, range 33-75 years] who underwent cervical TFESI were included in this non-randomized study. For cervical TFESI, triamcinolone was injected into 97 patients and dexamethasone into 62 patients. Short-term follow-up was conducted within 1 month. The outcome was classified as effective or ineffective. Fisher's exact test was used to analyze the difference of outcome according to the injected steroid (triamcinolone vs dexamethasone). Other possible outcome predictors, such as age, gender, duration of radiculopathy, predominant symptom, attack of radiculopathy, cause of radiculopathy, number of nerve root compression levels, previous operation, and failure of previous interlaminar epidural injection, were also analyzed. Cervical TFESI using triamcinolone (78/97, 80.4%) was slightly more effective than that using dexamethasone (43/62, 69.4%), which was not significant (P = 0.129). In general, cervical TFESIs were effective in 121 of 159 patients (76.1%) at short-term follow-up. The only significant outcome predictor was whether the patient had had a previous operation (6/13, 46/2%) or not (115/146, 78.8%) (P = 0.015). There was no significant difference between particulate or non-particulate steroid for the effect of cervical TFESI. Cervical TFESI was effective in managing cervical radiculopathy in general.

The aim of this study was to evaluate the effectiveness and safety of emergency cervical cerclage in women with advanced cervical dilatation and bulging of fetal membranes. The study included 158 women who underwent emergency cervical cerclage because of cervix dilatation and protruding membranes in mid-trimester at Sun Yat-sen Memorial Hospital of Sun Yat-sen University. Pregnancy outcomes and pregnancy outcome related to clinical features were analyzed retrospectively. Analysis revealed that the placement of emergency cerclage led to the delivery of live infants with a success rate of 82.28%. The mean interval between cerclage and delivery was 52.16.±26.62 days, with a mean gestation at delivery of 30.3±4.7 weeks and a mean birth weight of 1934.69±570.37 g. No severe maternal complications such as maternal death, hematosepsis, and hysterorrhexis occurred after the operation. Two women (1.25%) had laceration of the cervix, 1 woman (0.61%) suffered pulmonary edema, and 2 women (1.25%) developed deep vein thrombosis (DVT). There were significant correlations between the pregnancy outcome and risk factors, including any presenting symptoms, cervical dilatation, postoperative white blood cell count, and C-reactive protein (CRP) value. No significant difference was found in women with good vs. poor outcome in terms of maternal age and obstetric histories. Emergency cervical cerclage is effective in prolonging pregnancy and improving neonatal outcome in women with cervical incompetence. It should be considered a viable option for women with a dilated cervix in mid-trimester.

Full Text Available QuikClot combat gauze is a synthetic hemostatic dressing used for hemorrhage control. There is a paucity of data describing the clinical use and hemostatic results of combat gauze in the obstetric and gynecologic setting. This case series demonstrates the use of combat gauze as an effective hemostatic agent when used as vaginal packing in cervical and vaginal hemorrhage. Hemostasis was achieved rapidly in all cases and further interventions were avoided. The combat gauze remained in place for a mean time of 15 h with no adverse side effects observed. The use of combat gauze as vaginal packing may provide an alternative option in the treatment of cervical and vaginal hemorrhage when other traditional conservative and surgical interventions fail or are unavailable.

Cervical high-velocity low-amplitude (HVLA) manipulation technique is among the oldest and most frequently used chiropractic manual therapy, but the physiologic and biomechanics effects were not completely clear. This review aims to describe the effects of cervical HVLA manipulation techniques on range of motion, strength, and cardiovascular performance. A systematic search was conducted of the electronic databases from January 2000 to August 2016: PubMed (n = 131), ScienceDirect (n = 101), Scopus (n = 991), PEDro (n = 33), CINAHL (n = 884), and SciELO (n = 5). Two independent reviewers conducted the screening process to determine article eligibility. The intervention that included randomized controlled trials was thrust, or HVLA, manipulative therapy directed to the cervical spine. Methodological quality was assessed using the Cochrane risk-of-bias tool. The initial search rendered 2145 articles. After screening titles and abstracts, 11 articles remained for full-text review. The review shows that cervical HVLA manipulation treatment results in a large effect size (d > 0.80) on increasing cervical range of motion and mouth opening. In patients with lateral epicondylalgia, cervical HVLA manipulation resulted in increased pain-free handgrip strength, with large effect sizes (1.44 and 0.78, respectively). Finally, in subjects with hypertension the blood pressure seemed to decrease after cervical HVLA manipulation. Higher quality studies are needed to develop a stronger evidence-based foundation for HVLA manipulation techniques as a treatment for cervical conditions.

Cervical cancer continues to be a significant health burden worldwide. Globally, the majority of cancers are locally advanced at diagnosis; hence, radiation remains the most frequently used therapeutical modality. Currently, the value of adding cisplatin or cisplatin-based chemotherapy to radiation for treatment of locally advanced cervical cancer is strongly supported by randomized studies and meta-analyses. Nevertheless, despite these significant achievements, therapeutic results are far from optimal; thus, novel therapies need to be assayed. A strategy currently being investigated is the use of newer radiosensitizers alone or in combination with platinum compounds. In the present work, we present preclinical information on known and newer cytotoxic agents as radiosensitizers on cervical cancer models, as well as the clinical information emanating from early phase trials that incorporate them to the cervical cancer management. In addition, we present the perspectives on the combined approach of radiation therapy and molecular target-based drugs with proven radiosensitizing capacity

Paediatric patients with suspected cervical spine injury (CSI) are routinely immobilised on a firm surface using a hard collar, which results in excessive flexion of the cervical spine due to the relatively large size of the occiput. The objective of this study was to determine whether the use of a thoracic elevation device (TED) results in a more neutral cervical spine position and reduces the occurrence of cervical spine hyperflexion. A prospective cohort study was conducted at two Emergency Departments (sites A and B) from January 2006 to May 2007. Children TED and those at site B did not. x-Rays from both sites were analysed for flexion, extension or neutrality of the cervical spine as defined by the Cobb angle. A total of 76 patients were identified at site A and site B. There were four exclusions at each site for poor quality images. 51 patients in the site A group were found to be in neutral position (71%), compared to 29 patients in the site B group (43%) (p=0.001). One patient (1%) who had a TED was found to be hyperflexed (>10 degrees), whereas 12 (18%) patients at site B were hyperflexed (p=0.001). The use of a TED appears to produce a greater proportion of neutral cervical spine films in children < or =10 years of age presenting for suspected CSI.

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.

2017-06-01

Full Text Available Background: Neck pain has been reported as a prevalent musculoskeletal disorder globally with more than half of the general population being affected once or more within their life span. Methods: A randomized clinical trial research design was used which investigated the immediate effect of cervical manipulation on neck pain and cervical range of motion among patients with chronic mechanical neck pain. 20 male and female participants between the ages of 26 to 60 years with chronic mechanical neck pain attending physiotherapy clinics were recruited. They were randomly assigned into two groups (A and B of 10 patients each. Group A received soft tissue massage, and cervical manipulation and group B served as the control group, and they received only soft tissue massage. There were two outcomes measured; Pain intensity was rated using visual analog scale (VAS before and immediately after the intervention. Pre and Post intervention measurements of cervical spine range of motion using Goniometer were also taken. Results: Findings of the study revealed significant immediate improvement of pain and Cervical Range of Motions (p<0.05 in all dimensions in the experimental group while Pain, flexion and right side Cervical flexion significantly improved in the control group. It was also found out after comparing the outcomes between the two groups that, the experimental group had significantly (p<0.05 better improvement than the control group in post-intervention pain, cervical flexion, cervical extension and cervical (right and left lateral rotations. Conclusion: Cervical manipulation is effective in immediate pain relief and improvement in cervical range of motion in patients with mechanical neck pain

Full Text Available Despite declines in cervical cancer mortality in developed countries, cervical cancer incidence and mortality rates remain high in Jamaica due to low levels of screening. Effective interventions are needed to decrease barriers to preventive behaviors and increase adoption of behaviors and services to improve prospects of survival. We enrolled 225 women attending health facilities in an intervention consisting of a pre-test, educational presentation and post-test. The questionnaires assessed attitudes, knowledge, risk factors, and symptoms of cervical cancer among women. Changes in knowledge and intention to screen were assessed using paired t-tests and tests for correlated proportions. Participants were followed approximately six months post-intervention to determine cervical cancer screening rates. We found statistically significant increases from pre-test to post-test in the percentage of questions correctly answered and in participants’ intention to screen for cervical cancer. The greatest improvements were observed in responses to questions on knowledge, symptoms and prevention, with some items increasing up to 62% from pre-test to post-test. Of the 123 women reached for follow-up, 50 (40.7% screened for cervical cancer. This theory-based education intervention significantly increased knowledge of and intention to screen for cervical cancer, and may be replicated in similar settings to promote awareness and increase screening rates.

This study aims at evaluating and comparing the effects of cervical stability training to combined cervical and core stability training in patients with neck pain and cervical disc herniation. Fifty patients with neck pain and cervical disc herniation were included in the study, randomly divided into two groups as cervical stability and cervical-core stability. Training was applied three times a week in three phases, and lasted for a total duration of 8 weeks. Pain, activation and static endurance of deep cervical flexor muscles, static endurance of neck muscles, cross-sectional diameter of M. Longus Colli, static endurance of trunk muscles, disability and kinesiophobia were assessed. Pain, activation and static endurance of deep cervical flexors, static endurance of neck muscles, cross-sectional diameter of M. Longus Colli, static endurance of trunk muscles, disability and kinesiophobia improved in both groups following the training sessions (p training methods revealed that the cervical stability group produced a greater increase in the right transverse diameter of M. Longus Colli (p training provided benefit to patients with cervical disc herniation. The addition of core stability training did not provide any additional significant benefit. Further research is required to investigate the efficacy of combining other techniques with cervical stability training in patients with cervical disc herniation. Both cervical stability training and its combination with core stability training were significantly and similarly effective on neck pain and neck muscle endurance in patients with cervical disc herniation. © 2017 European Pain Federation - EFIC®.

2010-12-01

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.

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.

S Rajasekaran

2010-01-01

Full Text Available Background: Cervical pedicle screw fixation is challenging due to the small osseous morphometrics and the close proximity of neurovascular elements. Computer navigation has been reported to improve the accuracy of pedicle screw placement. There are very few studies assessing its efficacy in the presence of deformity. Also cervical pedicle screw insertion in children has not been described before. We evaluated the safety and accuracy of Iso-C 3D-navigated pedicle screws in the deformed cervical spine. Materials and Methods: Thirty-three patients including 15 children formed the study group. One hundred and forty-five cervical pedicle screws were inserted using Iso-C 3D-based computer navigation in patients undergoing cervical spine stabilization for craniovertebral junction anomalies, cervico-thoracic deformities and cervical instabilities due to trauma, post-surgery and degenerative disorders. The accuracy and containment of screw placement was assessed from postoperative computerized tomography scans. Results: One hundred and thirty (89.7% screws were well contained inside the pedicles. Nine (6.1% Type A and six (4.2% Type B pedicle breaches were observed. In 136 levels, the screws were inserted in the classical description of pedicle screw application and in nine deformed vertebra, the screws were inserted in a non-classical fashion, taking purchase of the best bone stock. None of them had a critical breach. No patient had any neurovascular complications. Conclusion: Iso-C navigation improves the safety and accuracy of pedicle screw insertion and is not only successful in achieving secure pedicle fixation but also in identifying the best available bone stock for three-column bone fixation in altered anatomy. The advantages conferred by cervical pedicle screws can be extended to the pediatric population also.

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

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

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.)

Malignant cervical tumors occupy the leading position among malignant neoplasms of reproductive system in women, second only to breast cancer, despite having far more effective screening compared with this disease. On predictive expert estimates (taking into account population growth and the expected increase in life expectancy by 2020 in developing countries, the rising incidence and prevalence of cervical cancer is 40%, while in developed countries - 11%. If we do not perform timely interventions for prevention and treatment of cervical cancer, after 2050 cervical cancer every year in the world will become sick 1 million women. In the last decade inRussiathere has been a gradual increase in the incidence of cervical cancer: average annual growth rate of 2.21%, General 25,18%. Cervical cancer is one of nosological forms that meet all the requirements of population-based screening.

The Faroe Islands have had nationally organised cervical cancer screening since 1995. Women aged 25-60 years are invited every third year. Participation is free of charge. Although several European overviews on cervical screening are available, none have included the Faroe Islands. Our aim was to provide the first description of cervical cancer screening, and to determine the screening history of women diagnosed with cervical cancer in the Faroe Islands. Screening data from 1996 to 2012 were obtained from the Diagnostic Centre at the National Hospital of the Faroe Islands. They included information on cytology and HPV testing whereas information on histology was not registered consistently. Process indicators were calculated, including coverage rate, excess smears, proportion of abnormal cytological samples, and frequency of HPV testing. Data on cervical cancer cases were obtained from the Faroese Ministry of Health Affairs. The analysis of the screening history was undertaken for cases diagnosed in 2000-2010. A total of 52 457 samples were taken in 1996-2012. Coverage varied between 67% and 81% and was 71% in 2012. Excess smears decreased after 1999. At present, 7.0% of samples have abnormal cytology. Of all ASCUS samples, 76-95% were tested for HPV. A total of 58% of women diagnosed with cervical cancer did not participate in screening prior to their diagnosis, and 32% had normal cytology in the previous four years. Despite the difficult geographical setting, the organised cervical cancer screening programme in the Faroe Islands has achieved a relatively high coverage rate. Nevertheless, challenges, e.g. consistent histology registration and sending reminders, still exist.

Cervical and thoracic spinal manipulative therapy has shown positive impact for relief of pain and improve function in non-specific mechanical neck pain. Several attempts have been made to compare their effectiveness although previous studies lacked a control group, assessed acute neck pain or combined thrust and non-thrust techniques. To compare the immediate effects of cervical and thoracic spinal thrust manipulations on mechanosensitivity of upper limb nerve trunks and grip strength in patients with chronic non-specific mechanical neck pain. Randomized, single-blinded, controlled clinical trial. Private physiotherapy clinical consultancy. Eighty-eight subjects (32.09±6.05 years; 72.7% females) suffering neck pain (grades I or II) of at least 12 weeks of duration. Participants were distributed into three groups: 1) cervical group (N.=28); 2) thoracic group (N.=30); and 3) control group (N.=30). One treatment session consisting of applying a high-velocity low-amplitude spinal thrust technique over the lower cervical spine (C7) or the upper thoracic spine (T3) was performed, while the control group received a sham-manual contact. Measurements were taken at baseline and after intervention of the pressure pain threshold over the median, ulnar and radial nerves. Secondary measures included assessing free-pain grip strength with a hydraulic dynamometer. No statistically significant differences were observed when comparing between-groups in any of the outcome measures (P>0.05). Those who received thrust techniques, regardless of the manipulated area, reported an immediate increase in mechanosensitivity over the radial (both sides) and left ulnar nerve trunks (Ppain perception over the radial nerve also improved (P≤0.025). Low-cervical and upper-thoracic thrust manipulation is no more effective than placebo to induce immediate changes on mechanosensitivity of upper limb nerve trunks and grip strength in patients with chronic non-specific mechanical neck pain.

Full Text Available Abstract Objective: The aim of this study was to investigate the effectiveness of Kinesio Taping and sham Kinesio Taping on pain, pressure pain threshold, cervical range of motion, and disability in cervical myofascial pain syndrome patients (MPS. Methods: This study was designed as a randomized, double-blind placebo controlled study. Sixty-one patients with MPS were randomly assigned into two groups. Group 1 (n = 31 was treated with Kinesio Taping and group 2 (n = 30 was treated sham taping five times by intervals of 3 days for 15 days. Additionally, all patients were given neck exercise program. Patients were evaluated according to pain, pressure pain threshold, cervical range of motion and disability. Pain was assessed by using Visual Analog Scale, pressure pain threshold was measured by using an algometer, and active cervical range of motion was measured by using goniometry. Disability was assessed with the neck pain disability index disability. Measurements were taken before and after the treatment. Results: At the end of the therapy, there were statistically significant improvements on pain, pressure pain threshold, cervical range of motion, and disability (p 0.05. Conclusion: This study shows that Kinesio Taping leads to improvements on pain, pressure pain threshold and cervical range of motion, but not disability in short time. Therefore, Kinesio Taping can be used as an alternative therapy method in the treatment of patients with MPS.

We investigated the incidence and clinical appearance of late adverse intestinal effects in 88 patients treated with postoperative radiotherapy and 46 patients treated with radiotherapy alone for uterine cervical cancer. In the postoperative radiotherapy group, colitis, ileus and bowel fistules were seen in 13 patients (14.8%), 8 (9.1%), and 3 (3.4%) of the patients, respectively. Of these patients, 11 (12.5%) needed to have surgical therapy for these adverse effects. In the radiation alone group, 18 patients (39.1%) had colitis and 2 (4.3%) had ileus; of them, 2 patients (4.3%) needed to have surgical therapy. The higher incidence of so severe adverse effects as to require surgical therapy in the postoperative radiotherapy group indicates that adhesion caused by operation might have caused the occurrence of these adverse effects. Four of a total of 134 patients died of causes which might be attributable to irradiation. In 61 patients treated by radical hysterectomy without postoperative radiotherapy, intestinal adverse effects were not found. These results indicate that late intestinal adverse effects after radiotherapy are likely to occur in some cases very severely; therefore, careful consideration is necessary in the decision to use radiotherpay for uterine cervical cancer.

Ochronotic arthropathy related to alkaptonuria is a rare condition. Cervical spine involvement with myelopathic features has been even more rarely described, particularly related to atlantoaxial instability. As such, little is known about the optimal surgical management in these patients. We described the first case, to our knowledge, of a patient with alkaptonuria and related cervical spondylotic myelopathy from pannus formation at the atlantoaxial joint. We describe our choices in surgical management of this rare condition in a patient with an excellent outcome. Ochronotic cervical spondylotic myelopathy is a rare condition and may require additional considerations in surgical treatment compared to more common causes of cervical spondylotic myelopathy. In our case, we elected for decompression with posterior occipitocervical screw fixation and were able to achieve neurologic recovery with no complications, currently at 2-year follow-up.

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

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.

To observe the effectiveness of acupuncture applied to the cervical region of patients with upper extremity radicular symptoms due to cervical spondylotic radiculopathy (CSR). 15 subjects diagnosed with CSR and with upper extremity pain and/or paraesthesiae for 13.1±18.0 months were selected. The 15 patients had 16 affected limbs and scored a total of 17 symptom scores of pain and/or paraesthesiae. All patients were treated with acupuncture once a week for 4 weeks at up to 10 sites in the cervical paraspinal region centred on the affected area. The severity of the symptoms was recorded using a visual analogue scale (VAS) and functional evaluation was conducted using a Neck Disability Index (NDI). A significant reduction over time was seen for both mean VAS (pCSR.

Several countries are implementing a transition to HPV testing for cervical screening in response to the introduction of HPV vaccination and evidence indicating that HPV screening is more effective than cytology. In Australia, a 2017 transition from 2-yearly conventional cytology in 18-20 to 69 years to 5-yearly primary HPV screening in 25 to 74 years will involve partial genotyping for HPV 16/18 with direct referral to colposcopy for this higher risk group. The objective of this study was to determine the optimal management of women positive for other high-risk HPV types (not 16/18) ('OHR HPV'). We used a dynamic model of HPV transmission, vaccination, natural history and cervical screening to determine the optimal management of women positive for OHR HPV. We assumed cytology triage testing was used to inform management in this group and that those with high-grade cytology would be referred to colposcopy and those with negative cytology would receive 12-month surveillance. For those with OHR HPV and low-grade cytology (considered to be a single low-grade category in Australia incorporating ASC-US and LSIL), we evaluated (1) the 20-year risk of invasive cervical cancer assuming this group are referred for 12-month follow-up vs. colposcopy, and compared this to the risk in women with low-grade cytology under the current program (i.e. an accepted benchmark risk for 12-month follow-up in Australia); (2) the population-level impact of the whole program, assuming this group are referred to 12-month surveillance vs. colposcopy; and (3) the cost-effectiveness of immediate colposcopy compared to 12-month follow-up. Evaluation was performed both for HPV-unvaccinated cohorts and cohorts offered vaccination (coverage ~72%). The estimated 20-year risk of cervical cancer is ≤1.0% at all ages if this group are referred to colposcopy vs. ≤1.2% if followed-up in 12 months, both of which are lower than the ≤2.6% benchmark risk in women with low-grade cytology in the current

Impaired cervical joint position sense is a feature of chronic neck pain and is commonly argued to rely on abnormal cervical input. If true, muscle vibration, altering afferent input, but not mental interventions, should have an effect on head repositioning acuity and neck pain perception. The aim of the present study was to determine the short-term effects of neck muscle vibration, motor imagery, and action observation on cervical joint position sense and pressure pain threshold in people with chronic neck pain. Forty-five blinded participants with neck pain received concealed allocation and were randomized in three treatment groups. A blinded assessor performed pre- and post-test measurement. Patients were recruited from secondary outpatient clinics in the southwest of Germany. Chronic, non specific neck pain patients without arm pain were recruited for this study. A single intervention session of 5 minutes was delivered to each blinded participant. Patients were either allocated to one of the following three interventions: (1) neck muscle vibration; (2) motor imagery; (3) action observation. Primary outcomes were cervical joint position sense acuity and pressure pain threshold. Repeated measures ANOVAs were used to evaluate differences between groups and subjects. Repositioning acuity displayed significant time effects for vibration, motor imagery, and action observation (all Ppain threshold demonstrated a time*group effect (P=0.042) as only vibration significantly increased pressure pain threshold (P=0.01). Although motor imagery and action observation did not modulate proprioceptive, afferent input, they nevertheless improved cervical joint position sense acuity. This indicates that, against the common opinion, changes in proprioceptive input are not prerequisite to improve joint repositioning performance. However, the short-term applications of these cognitive treatments had no effect on pressure pain thresholds, whereas vibration reduced pressure pain

Full Text Available We investigated the significance of high- mobility group box1 (HMGB1 and T-cell-mediated immunity and prognostic value in cervical cancer. HMGB1, forkhead/winged helix transcription factor p3 (Foxp3, IL-2, and IL-10 protein expression was analyzed in 100 cervical tissue samples including cervical cancer, cervical intraepithelial neoplasia (CIN, and healthy control samples using immunohistochemistry. Serum squamous cell carcinoma antigen (SCC-Ag was immunoradiometrically measured in 32 serum samples from 37 cases of squamous cervical cancer. HMGB1 and SCC-Ag were then correlated to clinicopathological characteristics. HMGB1 expression tends to increase as cervical cancer progresses and it was found to be significantly correlated to FIGO stage and lymph node metastasis. These findings suggest that HMGB1 may be a useful prognostic indicator of cervical carcinoma. In addition, there were significant positive relationships between HMGB1 and FOXP3 or IL-10 expression (both p < 0.05. In contrast, HMGB1 and IL-2 expression was negatively correlated (p < 0.05. HMGB1 expression may activate Tregs or facilitate Th2 polarization to promote immune evasion of cervical cancer. Elevated HMGB1 protein in cervical carcinoma samples was associated with a high recurrence of HPV infection in univariate analysis (p < 0.05. HMGB1 expression and levels of SCC-Ag were directly correlated in SCC (p < 0.05. Thus, HMGB1 may be a useful biomarker for patient prognosis and cervical cancer prediction and treatment.

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.

To compare the effects of cranio-cervical flexion vs cervical proprioception training on neuromuscular control, pressure pain sensitivity and perceived pain and disability in patients with chronic neck pain. Twenty-eight volunteers with chronic non-specific neck pain were randomly assigned to 1 of 2 interventions and undertook 6 physiotherapist-supervised sessions over a period of 2 months. Both groups performed daily home exercise. Performance on the cranio-cervical flexion test, pressure pain thresholds and reported levels of pain and disability were measured before and immediately after the first treatment session, 1 month after starting treatment and 2 months after starting treatment (at completion of the intervention). At 2 months, both groups improved their performance on the cranio-cervical flexion test (p  0.05). Both groups showed a reduction in their pain at rest and disability at 2 months, but this was also not different between groups (p > 0.05). Pressure pain sensitivity did not change for either group. Both specific cranio-cervical flexion training and proprioception training had a comparable effect on performance on the cranio-cervical flexion test, a test of the neuromuscular control of the deep cervical flexors. These results indicate that proprioception training may have positive effects on the function of the deep cervical flexors.

Operative Outcomes for Cervical Myelopathy and Radiculopathy

Full Text Available Cervical spondylotic myelopathy and radiculopathy are common disorders which can lead to significant clinical morbidity. Conservative management, such as physical therapy, cervical immobilisation, or anti-inflammatory medications, is the preferred and often only required intervention. Surgical intervention is reserved for those patients who have intractable pain or progressive neurological symptoms. The goals of surgical treatment are decompression of the spinal cord and nerve roots and deformity prevention by maintaining or supplementing spinal stability and alleviating pain. Numerous surgical techniques exist to alleviate symptoms, which are achieved through anterior, posterior, or circumferential approaches. Under most circumstances, one approach will produce optimal results. It is important that the surgical plan is tailored to address each individual's unique clinical circumstance. The objective of this paper is to analyse the major surgical treatment options for cervical myelopathy and radiculopathy focusing on outcomes and complications.

Human vagus nerve branching in the cervical region.

Directory of Open Access Journals (Sweden)

Niels Hammer

Full Text Available Vagus nerve stimulation is increasingly applied to treat epilepsy, psychiatric conditions and potentially chronic heart failure. After implanting vagus nerve electrodes to the cervical vagus nerve, side effects such as voice alterations and dyspnea or missing therapeutic effects are observed at different frequencies. Cervical vagus nerve branching might partly be responsible for these effects. However, vagus nerve branching has not yet been described in the context of vagus nerve stimulation.Branching of the cervical vagus nerve was investigated macroscopically in 35 body donors (66 cervical sides in the carotid sheath. After X-ray imaging for determining the vertebral levels of cervical vagus nerve branching, samples were removed to confirm histologically the nerve and to calculate cervical vagus nerve diameters and cross-sections.Cervical vagus nerve branching was observed in 29% of all cases (26% unilaterally, 3% bilaterally and proven histologically in all cases. Right-sided branching (22% was more common than left-sided branching (12% and occurred on the level of the fourth and fifth vertebra on the left and on the level of the second to fifth vertebra on the right side. Vagus nerves without branching were significantly larger than vagus nerves with branches, concerning their diameters (4.79 mm vs. 3.78 mm and cross-sections (7.24 mm2 vs. 5.28 mm2.Cervical vagus nerve branching is considerably more frequent than described previously. The side-dependent differences of vagus nerve branching may be linked to the asymmetric effects of the vagus nerve. Cervical vagus nerve branching should be taken into account when identifying main trunk of the vagus nerve for implanting electrodes to minimize potential side effects or lacking therapeutic benefits of vagus nerve stimulation.

OBJECTIVE Depression and anxiety have been demonstrated to have negative impacts on outcomes after spine surgery. In patients with cervical deformity (CD), the psychological and physiological burdens of the disease may overlap without clear boundaries. While surgery has a proven record of bringing about significant pain relief and decreased disability, the impact of depression and anxiety on recovery from cervical deformity corrective surgery has not been previously reported on in the literature. The purpose of the present study was to determine the effect of depression and anxiety on patients' recovery from and improvement after CD surgery. METHODS The authors conducted a retrospective review of a prospective, multicenter CD database. Patients with a history of clinical depression, in addition to those with current self-reported anxiety or depression, were defined as depressed (D group). The D group was compared with nondepressed patients (ND group) with a similar baseline deformity determined by propensity score matching of the cervical sagittal vertical axis (cSVA). Baseline demographic, comorbidity, clinical, and radiographic data were compared among patients using t-tests. Improvement of symptoms was recorded at 3 months, 6 months, and 1 year postoperatively. All health-related quality of life (HRQOL) scores collected at these follow-up time points were compared using t-tests. RESULTS Sixty-six patients were matched for baseline radiographic parameters: 33 with a history of depression and/or current depression, and 33 without. Depressed patients had similar age, sex, race, and radiographic alignment: cSVA, T-1 slope minus C2-7 lordosis, SVA, and T-1 pelvic angle (p > 0.05). Compared with nondepressed individuals, depressed patients had a higher incidence of osteoporosis (21.2% vs 3.2%, p = 0.028), rheumatoid arthritis (18.2% vs 3.2%, p = 0.012), and connective tissue disorders (18.2% vs 3.2%, p = 0.012). At baseline, the D group had greater neck pain (7.9 of

The aim of this study was to investigate the effectiveness of Kinesio Taping and sham Kinesio Taping on pain, pressure pain threshold, cervical range of motion, and disability in cervical myofascial pain syndrome patients (MPS). This study was designed as a randomized, double-blind placebo controlled study. Sixty-one patients with MPS were randomly assigned into two groups. Group 1 (n=31) was treated with Kinesio Taping and group 2 (n=30) was treated sham taping five times by intervals of 3 days for 15 days. Additionally, all patients were given neck exercise program. Patients were evaluated according to pain, pressure pain threshold, cervical range of motion and disability. Pain was assessed by using Visual Analog Scale, pressure pain threshold was measured by using an algometer, and active cervical range of motion was measured by using goniometry. Disability was assessed with the neck pain disability index disability. Measurements were taken before and after the treatment. At the end of the therapy, there were statistically significant improvements on pain, pressure pain threshold, cervical range of motion, and disability (pdisability (p>0.05). This study shows that Kinesio Taping leads to improvements on pain, pressure pain threshold and cervical range of motion, but not disability in short time. Therefore, Kinesio Taping can be used as an alternative therapy method in the treatment of patients with MPS. Copyright © 2016 Elsevier Editora Ltda. All rights reserved.

Cervical disc arthroplasty: Pros and cons.

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.

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.

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.

Purpose: The aim of this study was to evaluate efficacy of gynecologic examination under general anesthesia with cervical biopsies after (chemo) radiation for cervical cancer to identify patients with residual disease who may benefit from salvage surgery. Methods and Materials: In a retrospective cohort study data of all cervical cancer patients with the International Federation of Gynecology and Obstetrics (FIGO) Stage IB1 to IVA treated with (chemo) radiation between 1994 and 2001 were analyzed. Patients underwent gynecologic examination under anesthesia 8 to 10 weeks after completion of treatment. Cervical biopsy samples were taken from patients judged to be operable. In case of residual cancer, salvage surgery was performed. Results: Between 1994 and 2001, 169 consecutive cervical cancer patients received primary (chemo) radiation, of whom 4 were lost to follow-up. Median age was 56 years (interquartile range [IQR], 44-71) and median follow-up was 3.5 years (IQR, 1.5-5.9). In each of 111 patients a biopsy sample was taken, of which 90 (81%) showed no residual tumor. Vital tumor cells were found in 21 of 111 patients (19%). Salvage surgery was performed in 13 of 21 (62%) patients; of these patients, 5 (38%) achieved long-term, complete remission after salvage surgery (median follow-up, 5.2 years; range, 3.9-8.8 years). All patients with residual disease who did not undergo operation (8/21) died of progressive disease. Locoregional control was more often obtained in patients who underwent operation (7 of 13) than in patients who were not selected for salvage surgery (0 of 8 patients) (p < 0.05). Conclusions: Gynecologic examination under anesthesia 8 to 10 weeks after (chemo) radiation with cervical biopsies allows identification of those cervical cancer patients who have residual local disease, of whom a small but significant proportion may be salvaged by surgery

Randomized clinical trial. To compare the effectiveness of cervical spine thrust manipulation to that of Kinesio Taping applied to the neck in individuals with mechanical neck pain, using self-reported pain and disability and cervical range of motion as measures. The effectiveness of cervical manipulation has received considerable attention in the literature. However, because some patients cannot tolerate cervical thrust manipulation, alternative therapeutic options should be investigated. Eighty patients (36 women) were randomly assigned to 1 of 2 groups: the manipulation group, which received 2 cervical thrust manipulations, and the tape group, which received Kinesio Taping applied to the neck. Neck pain (11-point numeric pain rating scale), disability (Neck Disability Index), and cervical-range-of-motion data were collected at baseline and 1 week after the intervention by an assessor blinded to the treatment allocation of the patients. Mixed-model analyses of variance were used to examine the effects of the treatment on each outcome variable, with group as the between-subjects variable and time as the within-subjects variable. The primary analysis was the group-by-time interaction. No significant group-by-time interactions were found for pain (F = 1.892, P = .447) or disability (F = 0.115, P = .736). The group-by-time interaction was statistically significant for right (F = 7.317, P = .008) and left (F = 9.525, P = .003) cervical rotation range of motion, with the patients who received the cervical thrust manipulation having experienced greater improvement in cervical rotation than those treated with Kinesio Tape (Pcervical spine range of motion for flexion (F = 0.944, P = .334), extension (F = 0.122, P = .728), and right (F = 0.220, P = .650) and left (F = 0.389, P = .535) lateral flexion. Patients with mechanical neck pain who received cervical thrust manipulation or Kinesio Taping exhibited similar reductions in neck pain intensity and disability and similar

The aim of this study was to determine the effect of a clinical education initiative on the appropriate utilization of screening cervical spine CT in the emergency department. The purpose was to assess if clinical education can produce stricter adherence to the ACR Appropriateness Criteria and improve the utilization of screening CT examinations in the emergency department. Institutional review board approval was obtained for this HIPAA-compliant study. All adult patients presenting to a level 1 trauma center with blunt trauma prompting screening cervical spine CT were eligible. For each study, the requesting clinician completed a survey selecting all clinical indications. CT examinations were evaluated by a board-certified radiologist blinded to survey data. Results were compared with retrospective and prospective studies performed before the institution of the education initiative. Of the 388 cervical spine CT examinations performed, 12 (3.1%) were positive for acute cervical spine injury, compared to only 1.0% before the clinical education program (phase 2). Of the 376 examinations without injury, 13% met all 5 National Emergency X-Radiography Utilization Study criteria for nonimaging (down from 16.1% in phase 2), and 15 (4%) required no imaging when both National Emergency X-Radiography Utilization Study and abbreviated Canadian cervical spine rule criteria were applied. Implementation of a clinical education initiative resulted in improved adherence to ACR Appropriateness Criteria and improved clinical effectiveness of the studies by increasing fracture detection rate. Initiatives such as these could potentially influence imaging overutilization without burdening emergency department clinicians with excessive roadblocks to image ordering.

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.

There are many environmental considerations which may or may not lead to the development of faulty cervical mechanics. The design of near vision lenses could contribute to the development of such cervical dysfunction and consequently neck pain. Decision making regarding proper type of lens prescription seems important for presbyopic individuals. To investigate the effect of unifocal and multifocal lenses on cervical posture. Thirty subjects (18 females and 12 males) participated in the study with an age range from 40 to 64 years. Each subject wore consequently both unifocal and multifocal lenses randomly while reading. Then lateral cervical spine X-ray films were taken for each subject during each lens wearing. X-ray films were analyzed with digital software (Autocad software, 2 D) to measure segmental angles of the cervical vertebrae (Occiput/C1, C1/C2, C2/C3, C3/C4, C4/C5, C5/C6, C6/C7, C3/C7, C0/C3, and occiput/C7). Higher significant extension angle in the segments C0/C7, C1/C2, C5/C6, C6/C7, and C3/C7 (p<0.05) during multifocal lenses wearing were observed in contrast with higher flexion angle between C3/C4 and C4/C5 (p<0.05) with unifocal lenses wear. Multifocal lens spectacles produces increased extension in the cervical vertebrae angles when compared with the use of unifocal lenses.

Introduction: It is very common for patients with cervical cancer to be referred to the radiotherapy when the disease is in advanced stages, this fact determines high rates of locoregional recurrence. Radiation treatment causes actinic morphological changes, not only in neoplastic epithelial cells, but also in normal cells. These changes induced by radiation, often make difficult the differential diagnosis of the residual lesion, resulting in a dilemma in cytopathological follow-up. Objective: To describe the actinic cytopathologic changes in patients submitted to radiotherapy for cervical cancer. Methodology: The re-evaluation of cytopathologic smears and description of actinic cytopathic effects were performed. This information was complemented by the cytopathological report of the smears, available in the archives of the Division of Pathology (DIPAT) / INCA. Results: The most frequent cytopathological changes observed were: nuclear activation, cytoplasmic enhancement, cytoplasmic vacuolisation, eosinophilia, polychromasia, multinucleated giant cells, binucleation, nuclear vacuolisation, prominent nucleoli, as well as presence of leukocyte exudate. Conclusion: The cytopathological diagnosis of tumor persistence or recurrence after radiotherapy is always a great challenge for the professional, even the experienced one. Studies and reports in the literature on actinic cytopathologic changes and radiotherapy are scarce

Science.gov (United States)

Akhtar, Nida; Pathak, Kamla

2018-04-02

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.

To analyze the clinical characteristics and the surgical treatment strategy of cervical kyphosis. From March 2006 to October 2009, 31 cases of cervical kyphosis were treated. According to the clinical features and imaging findings, different treatment methods were used. There were 9 patients in operation group, including 4 male and 5 female patients, aged from 17 to 72 years (average age of 35 years). Among them, 5 cases were idiopathic kyphosis and 4 cases were caused by laminectomy or other reasons. There were 22 patients in conservative treatment group, including 11 male and 11 female patients, aged from 14 to 40 years (average age of 29 years), who were all idiopathic cervical kyphosis. Before and 1 week after operation, clinical assessment were taken for the patients in operation group using Spinal Cord Injuries Classification Standard of American Spinal Injury Association (AISA). During the periodic review, the anteroposterior, normal sagittal films of cervical spine were taken. At 1 week and every 6 months after operation, MRI films were also taken. These films were studied to evaluate the effects of the operations. In the conservative group, assessment of treatment results by studying anteroposterior and normal lateral views of cervical spine were were taken every month. The clinical characteristics and the surgical treatment strategies of these patients were analyzed. In operation group, 9 cases were followed up for 6 to 18 months, all patients did not failed in internal fixation and fusion. AISA neurological score and neurological function significantly improved. Three days after operation the average Cobb angle was -1.29 ° (preoperative 54.24 °). In conservative group, the average Cobb angle was -5.41 ° (before treatment 11.20 °) 4 months after the treatment. The symptoms of neck shoulder and back pain disappeared, and all patients were followed up for 3 to 24 months, with no recurrence of symptoms. In the early period of cervical kyphosis, adopt

Peng, Baogan; Pang, Xiaodong; Li, Duanming; Yang, Hong

2015-03-01

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.

To evaluate the skeletal maturation of male children with orofacial clefts using the cervical vertebral maturation (CVM) method. Case-control study. The School of Stomatology, Peking University. Subjects were 443 boys with cleft lip and/or cleft palate (CL/P) aged 8 to 16 years who were compared with 1772 boys without clefts in an age-matched control group. The 8- to 10-year-old boys of both groups were in CS1. Most of the 11- to 14-year-old boys without CL/P were in CS3 and CS4, though it was not so obvious in boys with CL/P. Most 15- to 16-year-old boys without CL/P were in CS5 and CS6, while there were a lot of boys with CL/P who were still in cervical stages before CS5. Clefts had a significant effect on growth, and boys without CL/P were 1.737 times more likely to have achieved higher cervical stages. From Mann-Whitney test of every age phase, the difference existed in each year of the age range of 11 to 16 years, except from 12 to 13 years (p  =  .100). In these age phases, the cervical stages of boys with CL/P were lower than those for boys without CL/P. By the age of 14, children with CL/P had a 4.679 times higher risk of delayed CS3, and the 95% confidence interval for the odds ratio was 2.129 to 10.286. Boys with CL/P are at a higher risk of delayed growth period and retarded pubertal growth peak.

Isometric cervical flexor system exercise (ICF) and isometric cervical extensor system exercise (ICE) are cervical stabilization techniques that have been used to restore cervical crossed syndrome (CCS)-associated forward head posture. However, the therapeutic effects and underlying motor control mechanisms remain elusive. The purpose of present study was investigating the concurrent therapeutic effects of ICF and ICE on muscle size, muscle imbalance ratio, and muscle recruitment sequence using ultrasound imaging and electromyography. A total of 18 participants (7 females; age=24±4.0 years) with CCS associated with forward head posture underwent ICF and ICE. Paired t-test analysis was used for statistical analysis. Paired t-test analysis showed that sternocleidomastoid thickness was greater during ICF than ICE. Similarly, cross-sectional area and horizontal thickness of the longus colli were greater during ICE than ICF. The upper trapezius/lower trapezius muscle imbalance ratio and the pectoralis major/lower trapezius muscle imbalance ratio were significantly decreased during the application of ICE compared to ICF. These results provide compelling, mechanistic evidence as to how ICE is more beneficial for the restoration of neuromuscular imbalance than ICF in individuals with CCS.

Spinal involvement is a common presentation of multiple myeloma (MM); however, the cervical spine is the least common site of myelomatous involvement. Few studies evaluate the results of percutaneous vertebroplasty (PV) in the treatment of MM of the spine. The purpose of this series is to report on the use of PV in the treatment of MM of the cervical spine and to review the literature. From January 1994 to October 2007, four patients (three men and one woman; mean age, 45 years) who underwent five PV for painful MM in the cervical spine were retrospectively reviewed. The pain was estimated by the patient on a verbal analogic scale. Clinical follow-up was available for all patients (mean, 27.5 months; range, 1-96 months). The mean volume of cement injected per vertebral body was 2.3 ± 0.8 mL (range, 1.0-4.0 mL) with a mean vertebral filling of 55.0 ± 12.0% (range, 40.0-75.0%). Analgesic efficacy was achieved in all patients. One patient had a spinal instability due to a progression of spinal deformity noted on follow-up radiographs, without clinical symptoms. Cement leakage was detected in three (60%) of the five treated vertebrae. There was no clinical complication. The present series suggests that PV for MM of the cervical spine is safe and effective for pain control; nonetheless, the detrimental impact of the disease on bone quality should prompt close radiological follow-up after PV owing to the risk of spinal instability.

Objective: To study the effects of extrinsic Smac gene transfection and its over-expression on radiotherapeutic sensitivity of cervical cancer cells, in order to explore a novel strategy for ameliorating radiotherapy of cervical cancer. Methods: After Smac gene was transferred into cells of cervical cancer cell line HeLa, the subclone cells were obtained by persistent G 418 selection. Cellular Smac gene expression was determined by RT-PCR and Western blot. After treatment with X-ray irradiation, cellular growth activity in vitro was investigated by MTT colorimetry. Cellular apoptosis and its rate were determined by electron microscopy, Annexin V-FITC and propidium iodide staining flow cytometry. Cellular Caspase-3 protein expression and its activity were assayed by Western blot and colorimetry. Results: RT-PCR and Western blot demonstrated that Smac mRNA and protein levels of HeLa/Smac cells, the selected subclone cells of cervical cancer cell line, were significantly higher than those of HeLa cells (P<0.01). After treated with 8 Gy X-ray irradiation, growth activity of HeLa/Smac cells reduced by 10.19%(P<0.01), as compared with that of HeLa cells. Partial HeLa/Smac cancer cells presented characteristic morphological changes of apoptosis under electron microscope, with an apoptosis rate of 16.4%, which was significantly higher than that of HeLa cells(6.2%, P<0.01). Compared with HeLa cells, Caspase-3 expression level in HeLa/Smac was improved significantly (P<0.01), while its activity was 3.42 times as much as that of HeLa cells (P<0.01). Conclusion: Stable transfection of extrinsic Smac gene and its over-expression in cervical cancer cell line could significantly enhance cellular caspase-3 expression and activity, ameliorate apoptosis-inducing effects of radiation on cancer cells, which would be a novel strategy to improve radiotherapeutic effects for cervical cancer.

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

Human papillomavirus (HPV) is one of the most widely publicized and researched pathogenic DNA viruses. For decades, HPV research has focused on transforming viral activities in cervical cancer. During the past 15 years, however, HPV has also emerged as a major etiological agent in cancers of the head and neck, in particular squamous cell carcinoma. Even with significant strides achieved towards the screening and treatment of cervical cancer, and preventive vaccines, cervical cancer remains the leading cause of cancer-associated deaths for women in developing countries. Furthermore, routine screens are not available for those at risk of head and neck cancer. The current expectation is that HPV vaccination will prevent not only cervical, but also head and neck cancers. In order to determine if previous cervical cancer models for HPV infection and transformation are directly applicable to head and neck cancer, clinical and molecular disease aspects must be carefully compared. In this review, we briefly discuss the cervical and head and neck cancer literature to highlight clinical and genomic commonalities. Differences in prognosis, staging and treatment, as well as comparisons of mutational profiles, viral integration patterns, and alterations in gene expression will be addressed.

Chronic persistent neck pain with or without upper extremity pain is common in the general adult population with prevalence of 48% for women and 38% for men, with persistent complaints in 22% of women and 16% of men. Multiple modalities of treatments are exploding in managing chronic neck pain along with increasing prevalence. However, there is a paucity of evidence for all modalities of treatments in managing chronic neck pain. Cervical epidural injections for managing chronic neck pain are one of the commonly performed interventions in the United States. However, the literature supporting cervical epidural steroids in managing chronic pain problems has been scant. A systematic review of cervical interlaminar epidural injections for cervical disc herniation, cervical axial discogenic pain, cervical central stenosis, and cervical postsurgery syndrome. To evaluate the effect of cervical interlaminar epidural injections in managing various types of chronic neck and upper extremity pain emanating as a result of cervical spine pathology. The available literature on cervical interlaminar epidural injections in managing chronic neck and upper extremity pain were reviewed. The quality assessment and clinical relevance criteria utilized were the Cochrane Musculoskeletal Review Group criteria as utilized for interventional techniques for randomized trials and the criteria developed by the Newcastle-Ottawa Scale criteria for observational studies. The level of evidence was classified as good, fair, and limited based on the quality of evidence developed by the U.S. Preventive Services Task Force (USPSTF). Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to December 2011, and manual searches of the bibliographies of known primary and review articles. The primary outcome measure was pain relief (short-term relief = up to 6 months and long-term > 6 months). Secondary outcome measures were improvement in functional status

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.

2018-01-01

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.

Artificial cervical disc replacement is expected to maintain normal cervical biomechanics. At present, the effect of the Prestige LP prosthesis height on cervical biomechanics has not been thoroughly studied. This finite element study of the cervical biomechanics aims to predict how the parameters, like range of motion (ROM), adjacent intradiscal pressure, facet joint force, and bone-implant interface stress, are affected by different heights of Prestige LP prostheses. The finite element model of intact cervical spine (C3-C7) was obtained from our previous study, and the model was altered to implant Prestige LP prostheses at the C5-C6 level. The effects of the height of 5, 6, and 7 mm prosthesis replacement on ROM, adjacent intradiscal pressure, facet joint force, as well as the distribution of bone-implant interface stress were examined. ROM, adjacent intradiscal pressure, and facet joint force increased with the prosthesis height, whereas ROM and facet joint force decreased at C5-C6. The maximal stress on the inferior surface of the prostheses was greater than that on the superior surface, and the stresses increased with the prosthesis height. The biomechanical changes were slightly affected by the height of 5 and 6 mm prostheses, but were strongly affected by the 7-mm prosthesis. An appropriate height of the Prestige LP prosthesis can preserve normal ROM, adjacent intradiscal pressure, and facet joint force. Prostheses with a height of ≥2 mm than normal can lead to marked changes in the cervical biomechanics and bone-implant interface stress. Copyright © 2018 Elsevier Inc. All rights reserved.

We aimed to investigate the diagnostic and therapeutic approaches in pharyngoesophageal perforation (PEP) following anterior cervical spine intervention (ACSI). We reviewed the records of four patients with PEP after ACSI. Symptoms, physical examination findings, imaging results, treatment, and follow-up characteristics were evaluated. All four patients had undergone ACSI for either cervical trauma or cervical disc herniation with cervical cage reconstruction. Symptoms developed within the first 10 days of the postoperative period in three patients, and in the eighth month in one patient. Mucosal defects were detected during neck exploration in three patients. Reconstruction with primary suture and a local muscle flap was utilized in two patients. Three patients were discharged 3-8 weeks after surgical treatment. In cases of PEP after ACSI, a good prognosis can be achieved when symptoms are detected in the early period and reconstruction with local muscle flap is applied.

Tan, Lee A; Straus, David C; Traynelis, Vincent C

2015-05-01

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

The overall aim of the work was to increase participation by Māori and Pacific women in the National Cervical Screening Programme (NCSP) in New Zealand using a social marketing informed approach. Key objectives for this target group included: increasing awareness, understanding and discussion of cervical cancer and cervical screening; increasing telephone calls to the NCSP's 0800 number; and increasing uptake of cervical screening. A social marketing intervention with mixed qualitative and quantitative evaluation. Focus groups with priority women and key stakeholder interviews were used to identify a set of key messages from which television, radio and print media advertisements were developed. The advertising campaign was one element of a broader programme of activity, which involved changes to service delivery and improvement to access to services, particularly for the target groups. The campaign was evaluated in three ways: quantitative surveys conducted before, during and after the intervention; monitoring the number of calls to the NCSP's 0800 number; and monitoring NCSP monthly coverage statistics. The social marketing intervention achieved measurable behavioural impacts with its primary target audiences, delivering significant increases in screening uptake by Māori (6.8%) and Pacific women (12.7%) after 12 months. In addition, there was a secondary positive impact on other women (not the immediate target audience) whose rate of update also increased (2.7%). Overall, the intervention helped to reduce inequalities and delivered substantial increases in awareness, understanding and discussion of cervical cancer and cervical screening amongst the target groups. The results demonstrate that social marketing can be effective in targeting marginalized or under-represented groups. The intervention has not only changed the way in which women in New Zealand talk about a previously 'taboo' subject, but it has also provided a platform for significant behaviour change

The potential to accurately perform cervical movements during more challenging tasks might be of importance to prevent dysfunctional motion characteristics. Although sensorimotor function during dual-task conditions are of increasing interest in biomedical and rehabilitation research, effects of such conditions on movement consistency of the neck have not yet been investigated. In this crossover MiSpEx(Medicine in Spine Exercise)-diagnostic study, we aimed to explore differences between single and dual-task conditions on cervical movement variability. Nineteen healthy participants (9 male; 24.5 ± 3.3 y) performed 10 repetitive maximal cervical movements in (1) flexion/extension and (2) lateral flexion, during one single- and during two dual-task test conditions (cognitive, motor) in a randomised and cross-over sequence. Latter consisted of a working memory n-back task (n= 2) and a repetitive ankle movement task. Range of motion (RoM) was assessed using an external three-dimensional ultrasonic movement analysis system. Coefficient of variation (CV) for repetitive RoM was analysed for differences between conditions and controlled for variances in intra-individual movement characteristics. Friedman and post-hoc Bonferroni-adjusted confidence intervals for differences from single- to dual-task values revealed changes in CV in flexion/extension from single-task to motor dual-task (+0.02 ± 0.02 (97.5%CI: 0.01; 0.03); pdual-task condition (+0.01 ± 0.02 (97.5%CI: 0.003; 0.02)) nor for lateral flexion (p> 0.05). Pearson regression analyses revealed a linear negative (pdual-task (R=2 0.55). Results for lateral flexion are comparable, baseline CV negatively impacts differences to cognitive (R=2 0.2) and motor dual-task performance (R=2 0.76; pdual-task conditions while participants with a higher variability remained almost stable or showed a decrease. The results point toward a complex interrelationship of motion patterns and adaptation processes during challenging tasks

Patients with advanced or recurrent cervical cancer have poor prognosis, and their 1-year survival is only 10%-20%. Chemotherapy is considered as the standard treatment for patients with advanced or recurrent cervical cancer, and cisplatin appears to treat the disease effectively. However, resistance to cisplatin may develop, thus substantially compromising the efficacy of cisplatin to treat advanced or recurrent cervical cancer. In this article, we systematically review the recent literature and summarize the recent advances in our understanding of the molecular mechanisms underlying cisplatin resistance in cervical cancer.

Full Text Available Abstract Background Screening tests for cervical cancer are effective in reducing the disease burden. In Thailand, a Pap smear program has been implemented throughout the country for 40 years. In 2008 the Ministry of Public Health (MoPH unexpectedly decided to scale up the coverage of free cervical cancer screening services, to meet an ambitious target. This study analyzes the processes and factors that drove this policy innovation in the area of cervical cancer control in Thailand. Methods In-depth interviews with key policy actors and review of relevant documents were conducted in 2009. Data analysis was guided by a framework, developed on public policy models and existing literature on scaling-up health care interventions. Results Between 2006 and 2008 international organizations and the vaccine industry advocated the introduction of Human Papillomavirus (HPV vaccine for the primary prevention of cervical cancer. Meanwhile, a local study suggested that the vaccine was considerably less cost-effective than cervical cancer screening in the Thai context. Then, from August to December 2008, the MoPH carried out a campaign to expand the coverage of its cervical cancer screening program, targeting one million women. The study reveals that several factors were influential in focusing the attention of policymakers on strengthening the screening services. These included the high burden of cervical cancer in Thailand, the launch of the HPV vaccine onto the global and domestic markets, the country’s political instability, and the dissemination of scientific evidence regarding the appropriateness of different options for cervical cancer prevention. Influenced by the country’s political crisis, the MoPH’s campaign was devised in a very short time. In the view of the responsible health officials, the campaign was not successful and indeed, did not achieve its ambitious target.

The aim of the study was to develop and validate measures of awareness of symptoms and risk factors for ovarian and cervical cancer (Ovarian and Cervical Cancer Awareness Measures). Potentially relevant items were extracted from the literature and generated by experts. Four validation studies were carried out to establish reliability and validity. Women aged 21-67 years (n=146) and ovarian and cervical cancer experts (n=32) were included in the studies. Internal reliability was assessed psychometrically. Test-retest reliability was assessed over a 1-week interval. To establish construct validity, Cancer Awareness Measure (CAM) scores of cancer experts were compared with equally well-educated comparison groups. Sensitivity to change was tested by randomly assigning participants to read either a leaflet giving information about ovarian/cervical cancer or a leaflet with control information, and then completing the ovarian/cervical CAM. Internal reliability (Cronbach's α=0.88 for the ovarian CAM and α=0.84 for the cervical CAM) and test-retest reliability (r=0.84 and r=0.77 for the ovarian and cervical CAMs, respectively) were both high. Validity was demonstrated with cancer experts achieving higher scores than controls [ovarian CAM: t(36)= -5.6, pcancer leaflet scored higher than those who received a control leaflet [ovarian CAM: t(49)=7.5, pcancer awareness in the general population.

Uterine cervical cancer is still the second largest cancer in women worldwide, despite of effective screening methods. Radiotherapy is used to treat all the stages of cervical cancer and more than 60% of cervical cancer patients receive radiotherapy. New therapeutic targets or approaches are needed to further increase the results of radiotherapy. In the present study, we demonstrated the radiation induced overexpression and nuclear export of FTS in cervical cancer cells.

Decision-analytic modeling to evaluate the long-term effectiveness and cost-effectiveness of HPV-DNA testing in primary cervical cancer screening in Germany

Directory of Open Access Journals (Sweden)

Krämer, Alexander

2010-01-01

Full Text Available Background: Persistent infections with high-risk types of human papillomavirus (HPV are associated with the development of cervical neoplasia. Compared to cytology HPV testing is more sensitive in detecting high-grade cervical cancer precursors, but with lower specificity. HPV based primary screening for cervical cancer is currently discussed in Germany. Decisions should be based on a systematic evaluation of the long-term effectiveness and cost-effectiveness of HPV based primary screening. Research questions: What is the long-term clinical effectiveness (reduction in lifetime risk of cervical cancer and death due to cervical cancer, life years gained of HPV testing and what is the cost-effectiveness in Euro per life year gained (LYG of including HPV testing in primary cervical cancer screening in the German health care context? How can the screening program be improved with respect to test combination, age at start and end of screening and screening interval and which recommendations should be made for the German health care context? Methods: A previously published and validated decision-analytic model for the German health care context was extended and adapted to the natural history of HPV infection and cervical cancer in order to evaluate different screening strategies that differ by screening interval, and tests, including cytology alone, HPV testing alone or in combination with cytology, and HPV testing with cytology triage for HPV-positive women. German clinical, epidemiological and economic data were used. In the absence of individual data, screening adherence was modelled independently from screening history. Test accuracy data were retrieved from international meta-analyses. Predicted outcomes included reduction in lifetime-risk for cervical cancer cases and deaths, life expectancy, lifetime costs, and discounted incremental cost-effectiveness ratios (ICER. The perspective of the third party payer and 3% annual discount rate were

ALDO CALADO

Full Text Available ABSTRACT Objectives: To quantify the changes in cervical sagittal alignment of patients with adolescent idiopathic scoliosis (AIS who underwent surgical treatment. Methods: Retrospective study of radiographic data analysis. Data were collected from 25 radiographs of patients with AIS, and 18 cases were included. The mean age was 15.2 years (13-17 years; all subjects were female, operated from March 2010 to October 2015. Pre and postoperatively, cervical lordosis (C2-C7, thoracic kyphosis (T5-T12 and lumbar lordosis (L1-S1 were measured. Scoliotic curves were analyzed and measured in anterior posterior views by the Cobb method and classified according to the Lenke classification. Results: Eighteen adolescent patients were evaluated with a mean follow-up of 31.3 months. There was a negative correlation (-0.613 between post-surgical and pre-surgical cervical lordosis variation, that is, the largest the angulations obtained, on average, the greatest the reductions. Thus, the correlation becomes positive when compared to postoperative period (0.579. Conclusion: We concluded that the correction of adolescent idiopathic scoliosis did not bring about statistically significant changes in the cervical spine, with respect to angle values. Lordotic cervical curves with greater angular value showed a greater variation in the postoperative period, resulting in a better biomechanical balance.

Objective : To evaluate the skeletal maturation of girls with orofacial clefts using the cervical vertebral maturation method. Design : Case-control study. Setting : The School of Stomatology, Peking University. Patients : A total of 173 girls with cleft lip and/or palate from 8 to 16 years old were compared with 1038 age-matched girls without clefts. Results : In the 8- to 9-year-olds, most of the girls from both groups were in cervical stage 1. In the 14- to 15-year-olds and 15- to 16-year-olds, almost all the girls from both groups were in cervical stages 5 and 6, and most of the 15- to 16-year-old girls were in cervical stage 6. Differences existed in each year for 9- to 14-year-olds, which was confirmed by statistical analysis. After ordinal logistical regression of data from girls 9 to 14 years of age, girls of the same age in the non-cleft lip and/or palate group were associated with 1.559 times the odds of having achieved higher cervical stages than those in the cleft lip and/or palate group. Most girls without cleft lip and/or palate were in cervical stages 3 and 4 in the 11- to 12-year-olds; whereas, it was not so obvious in the girls with cleft lip and/or palate. By the age of 12, girls with cleft lip and/or palate had 2.667 times the risk of delayed cervical stage 3, and the 95% confidence interval for the odds ratio was 1.013 to 7.019. Conclusions : Girls with cleft lip and/or palate are at a higher risk of delayed pubertal growth.

The application of picosecond pulsed electric field (psPEF) is a new biomedical engineering technique used in cancer therapy. However, its effects on cervical cancer angiogenesis are not clear. Therefore, the aim of the present study is to investigate the effects of psPEF on angiogenesis in cervical cancer xenograft models. Xenograft tumors were created by subcutaneously inoculating nude mice (athymic BALB/c nu/nu mice) with HeLa cells, then were placed closely between tweezer-type plate electrodes and subjected to psPEF with a gradually increased electric field intensity (0kV/cm, 50kV/cm, 60kV/cm, 70kV/cm). The direct effect on tumor tissue was observed by hematoxylin and eosin (H&E) staining and transmission electron microscopy (TEM). The changes of blood vessels and oxygen saturation (sO2) of tumors were monitored in vivo by photoacoustic tomography (PAT). The microvessel density (MVD), vascular endothelial growth factor (VEGF) and hypoxia-inducible transcription factors (HIF-1α and HIF-2α) were detected by immunohistochemical technique (IHC). Their protein expressions and gene transcription levels were evaluated using western blot (WB) and quantitative reverse transcription and polymerase chain reaction (RT-PCR). PsPEF induced obvious necrosis of cervical cancer tissue; with the increasing of electric field intensity, the MVD, vascular PA signal and sO2 values declined significantly. The protein expression and gene transcription levels of VEGF, HIF1α and HIF2α were significantly decreased at the same time. PsPEF exhibited dramatic anti-tumor and anti-angiogenesis effects in cervical cancer xenograft models by exerting direct effect on cancer cells and vascular endothelial cells and indirect effect on tumor angiogenesis-related factors.

Does pain relief by CT-guided indirect cervical nerve root injection with local anesthetics and steroids predict pain relief after decompression surgery for cervical nerve root compression?

Science.gov (United States)

Antoniadis, Alexander; Dietrich, Tobias J; Farshad, Mazda

2016-10-01

The relationship of pain relief from a recently presented CT-guided indirect cervical nerve root injection with local anesthetics and steroids to surgical decompression as a treatment for single-level cervical radiculopathy is not clear. This retrospective study aimed to compare the immediate and 6-week post-injection effects to the short- and long-term outcomes after surgical decompression, specifically in regard to pain relief. Patients (n = 39, age 47 ± 10 years) who had undergone CT-guided indirect injection with local anesthetics and steroids as an initial treatment for single cervical nerve root radiculopathy and who subsequently needed surgical decompression were included retrospectively. Pain levels (VAS scores) were monitored before, immediately after, and 6 weeks after injection (n = 34), as well as 6 weeks (n = 38) and a mean of 25 months (SD ± 12) after surgical decompression (n = 36). Correlation analysis was performed to find potential associations of pain relief after injection and after surgery to investigate the predictive value of post-injection pain relief. There was no correlation between immediate pain relief after injection (-32 ± 27 %) and 6 weeks later (-7 ± 19 %), (r = -0.023, p = 0.900). There was an association by tendency between immediate pain relief after injection and post-surgical pain relief at 6 weeks (-82 ± 27 %), (r = 0.28, p = 0.08). Pain relief at follow-up remained high at -70 ± 21 % and was correlated with the immediate pain amelioration effect of the injection (r = 0.37, p = 0.032). Five out of seven patients who reported no pain relief from injection had a pain relief from surgery in excess of 50 %. The amount of immediate radiculopathic pain relief after indirect cervical nerve root injection is associated with the amount of pain relief achieved at long-term follow-up after surgical decompression of single-level cervical radiculopathy

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.

Cytotoxic effects of alkaloids on cervical carcinoma cell lines: a review

2016-07-01

Full Text Available Cervical cancer is the fourth type of women neoplasia, with thousands of new cases annually. It is closely related to human papillomavirus (HPV infection, which has more than 13 oncogenic types, among them HPV 16 and 18 are implicated in 70% of cervical carcinoma cases. Alkaloids are nitrogenated and naturally occurring compounds, showing several uses in medical treatment, including cytotoxic and antineoplastic activities. In this work we aim to evaluate the cytotoxic and chemotherapeutic potential of alkaloids against cervical cancer. In order to accomplish this purpose, we have made a survey of potentially effective alkaloids with cytotoxic activities over HPV-16+ and HPV-18 + cells (HeLa cells. Through a literature review between the years of 1980 and 2015, we described the major alkaloid sources, distribution in nature and also discussed the mechanisms of action for their cytotoxicity. We found that alkaloids showed efficacy as cytotoxic agents, inhibiting cell growth of the HPV-transformed cells in vitro and in vivo by means of activation of intrinsic and extrinsic pathways of apoptosis, which included the clivage of caspases and PARP-1 (Poli-Adenosyl- Ribose Protease 1, increase in p53 expression, release of cytochrome C and increase of cell death receptors expression like Fas, mainly observed in HeLa (HPV- 18 + cell lines. Moreover, these secondary metabolites helped in modulating the MDR (Multi-Drug Resistance against the cell lines studied, which lead us to suggest their possible use as chemotherapeutic agents on the lesions caused by these virusesKeywords: Cervical cancer.

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.

2008-12-02

Human papillomavirus (HPV) vaccines provide an opportunity to reduce the incidence of cervical cancer. Optimization of cervical cancer prevention programs requires anticipation of the degree to which the public will adhere to vaccination recommendations. To compare vaccination levels driven by public perceptions with levels that are optimal for maximizing the community's overall utility, we develop an epidemiological game-theoretic model of HPV vaccination. The model is parameterized with survey data on actual perceptions regarding cervical cancer, genital warts, and HPV vaccination collected from parents of vaccine-eligible children in the United States. The results suggest that perceptions of survey respondents generate vaccination levels far lower than those that maximize overall health-related utility for the population. Vaccination goals may be achieved by addressing concerns about vaccine risk, particularly those related to sexual activity among adolescent vaccine recipients. In addition, cost subsidizations and shifts in federal coverage plans may compensate for perceived and real costs of HPV vaccination to achieve public health vaccination targets.

Full Text Available Abstract Background The cervical cancer screening program implemented in Hungary to date has not been successful. Along with screening, vaccination is an effective intervention to prevent cervical cancer. The aim of this study was to assess the cost-effectiveness of adding vaccination with the human papillomavirus 16/18 vaccine to the current cervical cancer screening program in Hungary. Methods We developed a cohort simulation state-transition Markov model to model the life course of 12-year-old girls. Eighty percent participation in the HPV vaccination program at 12 years of age was assumed. Transitional probabilities were estimated using data from the literature. Local data were used regarding screening participation rates, and the costs were estimated in US $. We applied the purchasing power parity exchange rate of 129 HUF/$ to the cost data. Only direct health care costs were considered. We used a 3.7% discount rate for both the cost and quality-adjusted life years (QALYs. The time horizon was 88 years. Results Inclusion of HPV vaccination at age 12 in the cervical cancer prevention program was predicted to be cost-effective. The incremental cost-effectiveness ratio (ICER of adding HPV vaccination to the current national cancer screening program was estimated to be 27 588 $/QALY. The results were sensitive to the price of the vaccine, the discount rate, the screening participation rate and whether herd immunity was taken into account. Conclusions Our modeling analysis showed that the vaccination of 12-year-old adolescent girls against cervical cancer with the AS04-adjuvanted human papillomavirus 16/18 vaccine would be a cost-effective strategy to prevent cervical cancer in Hungary.

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

Purpose: To estimate dose-volume effects in the rat cervical spinal cord with protons. Methods and Materials: Wistar rats were irradiated on the cervical spinal cord with a single fraction of unmodulated protons (150-190 MeV) using the shoot through method, which employs the plateau of the depth-dose profile rather than the Bragg peak. Four different lengths of the spinal cord (2, 4, 8, and 20 mm) were irradiated with variable doses. The endpoint for estimating dose-volume effects was paralysis of fore or hind limbs. Results: The results obtained with a high-precision proton beam showed a marginal increase of ED 50 when decreasing the irradiated cord length from 20 mm (ED 50 = 20.4 Gy) to 8 mm (ED 50 = 24.9 Gy), but a steep increase in ED 50 when further decreasing the length to 4 mm (ED 50 = 53.7 Gy) and 2 mm (ED 50 = 87.8 Gy). These results generally confirm data obtained previously in a limited series with 4-6-MV photons, and for the first time it was possible to construct complete dose-response curves down to lengths of 2 mm. At higher ED 50 values and shorter lengths irradiated, the latent period to paralysis decreased from 125 to 60 days. Conclusions: Irradiation of variable lengths of rat cervical spinal cord with protons showed steeply increasing ED 50 values for lengths of less than 8 mm. These results suggest the presence of a critical migration distance of 2-3 mm for cells involved in regeneration processes

To report extremely rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Only six cases of thoracic ligamentum flavum hematomas and three cases of cervical ligamentum flavum hematomas have been reported so far. Two patients presented with tetraparesis and one patient presented with radicular pain and paresthesias in the T3 dermatome. MRI was performed in two patients, which showed a posterior intraspinal mass, continuous with the ligamentum flavum. The mass was moderately hypointense on T2-weighted images and hyperintense on T1-weighted images with no contrast enhancement. The third patient underwent cervical myelography because of a cardiac pacemaker. The myelography showed an intraspinal posterior mass with compression of the dural sac at C3/C4. All patients underwent a hemilaminectomy to resect the ligamentum flavum hematoma and recovered completely afterwords, and did not experience a recurrence during follow-up of at least 2 years. This case series shows rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Surgery achieved complete recovery of the preoperative symptoms in all patients within days.

The rheumatoid cervical spine: Signs of instability on plain cervical radiographs

International Nuclear Information System (INIS)

Roche, Clare J.; Eyes, Brian E.; Whitehouse, Graham H.

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.

Issues in cervical cancer incidence and treatment in HIV.

Cervical disease burden continues to be especially high in HIV-infected women, even in the era of effective antiretroviral medications. This review discusses the multiple issues surrounding HIV-associated cervical cancer. Also, the unique treatment-related issues in HIV-associated cervical cancer are addressed. The incidence of invasive cervical cancer has remained stable in industrialized nations; however, it is only estimated in developing countries secondary to a relative lack of data collection and registries. Trends in HIV-associated cervical cancer have changed in the highly active antiretroviral therapy (HAART) era. Recent molecular pathways suggest that the natural progression of human papillomavirus infection, the causal agent in all cervical cancers, may be related to immune system dysfunction as well as HIV/human papillomavirus synergistic mechanisms. When highly active retroviral therapies are used, invasive cervical cancer treatments are impacted by concomitant drug toxicities that could potentially limit therapeutic benefit of either HAART or the standard of care treatment for locally advanced cervical cancer, concomitant chemoradiotherapy. The significance and care of the patient with invasive cervical cancer is becoming a geographically relevant phenomenon such that it may be time to re-address the global definition. Further studies in treatment issues and drug-drug interactions with cervical cancer treatments in the setting of HIV are paramount.

Full Text Available Minoo Robati, David Holtz, Charles J DuntonDepartment of Obstetrics and Gynecology, Main Line Gynecologic Oncology, Lankenau Hospital, Wynnewood, PA, USAAbstract: Treatment of advanced, recurrent or persistent cervical cancer includes radiotherapy and chemotherapy. Radiation has been the primary treatment modality for locoregionally advanced cervical cancer. Concomitant systemic cisplatin chemotherapy and radiation have shown high response rates with improvements in durable remissions and overall survival. Cisplatin has been the standard medication for the treatment of advanced cervical cancer. Combinations with other chemotherapeutic agents have been the subject of clinical trials with varying results. The toxicity of combination chemotherapy and tolerability of patients are other factors that should be considered in the management of patients with advanced disease. Recently topotecan, in combination with cisplatin, achieved increased response and overall survival rates without further compromising the patients’ quality of life. This review focuses on the mechanism of action and toxicities of topotecan, as well as its role as a radio-sensitizer and chemotherapeutic agent in the management of advanced, recurrent, or persistent cervical cancer. Other combination modalities and dosages are also discussed.Keywords: topotecan, combination chemotherapy, advanced cervical cancer

Abstract The aim of the study was to evaluate the role of the longus colli muscles in cervical vertigo. We retrospectively analyzed 116 adult patients who underwent anterior cervical discectomy and fusion (ACDF) during 2014 in our department. Patients were assigned to the vertigo group or the nonvertigo group. Demographic data were recorded. Inner distance and cross-sectional area (CSA) of longus colli were measured using coronal magnetic resonance imaging (MRI). The vertigo group (n = 44) and the nonvertigo group (n = 72) were similar in demographic data. Mean preoperative Japanese Orthopaedic Association (JOA) score was higher in the vertigo group than in the nonvertigo group (P = 0.037), but no difference postoperatively. Mean JOA scores increased significantly postoperatively in both groups (P = 0.002 and P = 0.001). The mean vertigo score decreased significantly from pre- to postoperatively in the vertigo group (P = 0.023). The mean preoperative Cobb angle was significantly smaller in the vertigo group than in the nonvertigo group (P vertigo group (P vertigo group (P vertigo group than in the nonvertigo group. Mean Miyazaki scores were significantly higher in the vertigo group at C3/4 and C4/5 (P = 0.044 and P = 0.037). Moreover, a shorter inner distance and smaller CSA were related to a higher Miyazaki score. Inner distance and cross-sectional area (CSA) of longus colli are associated closely with cervical vertigo. Shorter inner distance and smaller CSA of the longus colli muscles might be risk factors for cervical vertigo. ACDF provided a good resolution of cervical vertigo. PMID:28328822

This study aimed to describe the case of a 3-year-old girl with old bilateral facet dislocation on cervical vertebrae 6 and 7, who had spinal cord transection, received surgical treatment, and achieved a relative satisfactory therapeutic effect. A 3-year-old girl was urgently transferred to the hospital after a car accident. DIAGNOSES:: she was diagnosed with splenic rupture, intracranial hemorrhage, cervical dislocation, spinal transection, and Monteggia fracture of the left upper limb. The girl underwent emergency splenectomy and was transferred to the intensive care unit of the hospital 15 days later. One-stage anterior-posterior approach surgery (anterior discectomy, posterior laminectomy, and pedicle screw fixation) was performed when the patient stabilized after 45-day symptomatic treatment. The operation was uneventful. The reduction of lower cervical dislocation was satisfactory, with sufficient spinal cord decompression. The internal fixation position was good, and the spinal sequence was well restored. The girl was discharged 2 weeks later after the operation and followed up for 2 years. The major nerve function of both upper limbs was recovered, with no obvious retardation of the growth of immature spine. A satisfactory therapeutic effect was achieved for a pediatric old subaxial cervical dislocation with bilateral locked facets using anterior discectomy, posterior laminectomy, and pedicle screw fixation. The posterior pedicle screw fixation provided a good three-dimensional stability of the spine, with reduced risk and complications caused by anterior internal fixation. The growth of immature spine was not obviously affected during the 2-year follow-up.

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.

Analysis of right anterolateral impacts: the effect of trunk flexion on the cervical muscle whiplash response

2006-05-01

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.

In dressage, the head and neck position has become an issue of concern as certain extreme positions may imply a welfare risk for the horse. In man, extension and flexion of the cervical spine cause a decrease and increase in intervertebral foramina dimensions, respectively. However, in horses, the influence of flexion and extension on foramina dimensions and its possible interference with peripheral nerve functioning remains unknown. To determine the effect of ex vivo flexion and extension on intervertebral foramina dimensions in the equine cervical spine. Computed tomography was performed on 6 cadaver cervical spines from adult Warmblood horses subjected to euthanasia for reasons unrelated to cervical spine abnormalities, in a neutral position, in 20 and 40° extension, and in 20 and 40° flexion. Multiplanar reconstructions were made to obtain transverse images perpendicular to the long axis of each pair of intervertebral foramina from C2-T1. Intervertebral foramina dimensions were measured in the 5 positions. Compared to the neutral position, 40° extension caused a decrease in foramina dimensions at segments C4-C5, C5-C6, C6-C7 (P dimensions at segments C5-C6 (P dimensions at segments C4-T1, similar to that found in man. In vivo extension of the cervical spine could possibly interfere with peripheral nerve functioning at segments C4-T1. This effect may be even more profound in patients with a reduced intervertebral foramina space, for example in the presence of facet joint arthrosis. © 2010 EVJ Ltd.

Professional responsibility in relation to cervical spine manipulation.

Manipulation of the cervical spine is one of the few potentially life-threatening procedures performed by physiotherapists. Is it worth the risk? A comparison of risks versus benefits indicates that at present, the risks of cervical manipulation outweigh the benefits: manipulation has yet to be shown to be more effective for neck pain and headache than other interventions such as mobilisation, whereas the risks, although infrequent, are serious. This analysis is of particular concern because the conditions for which manipulation is indicated are benign and usually self-limiting. Because physiotherapists have legal and ethical obligations to the community to avoid foreseeable harm and provide optimum care, it may be prudent to determine who in our profession should perform cervical manipulation. That is, the profession could restrict the practice of cervical spine manipulation. Although all registered physiotherapists in Australia are entitled to perform cervical manipulation, few choose to use this intervention. Therefore, it might be feasible to encourage those practitioners who wish to use cervical manipulation to undertake formal education programs. Such a requirement could be embodied in a code of practice that discourages those without formal training from performing cervical manipulation. By taking such measures, we could ensure that our profession exercises wisdom in its monitoring and use of cervical manipulation.

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

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.

Estonia has high cervical cancer incidence and low screening coverage. We modelled the impact of population-based bivalent, quadrivalent or nonavalent HPV vaccination alongside cervical cancer screening. A Markov cohort model of the natural history of HPV infection was used to assess the cost-effectiveness of vaccinating a cohort of 12-year-old girls with bivalent, quadrivalent or nonavalent vaccine in two doses in a national, school-based vaccination programme. The model followed the natural progression of HPV infection into subsequent genital warts (GW); premalignant lesions (CIN1-3); cervical, oropharyngeal, vulvar, vaginal and anal cancer. Vaccine coverage was assumed to be 70%. A time horizon of 88years (up to 100years of age) was used to capture all lifetime vaccination costs and benefits. Costs and utilities were discounted using an annual discount rate of 5%. Vaccination of 12-year-old girls alongside screening compared to screening alone had an incremental cost-effectiveness ratio (ICER) of €14,007 (bivalent), €14,067 (quadrivalent) and €11,633 (nonavalent) per quality-adjusted life-year (QALY) in the base-case scenario and ranged between €5367-21,711, €5142-21,800 and €4563-18,142, respectively, in sensitivity analysis. The results were most sensitive to changes in discount rate, vaccination regimen, vaccine prices and cervical cancer screening coverage. Vaccination of 12-year-old girls alongside current cervical cancer screening can be considered a cost-effective intervention in Estonia. Adding HPV vaccination to the national immunisation schedule is expected to prevent a considerable number of HPV infections, genital warts, premalignant lesions, HPV related cancers and deaths. Although in our model ICERs varied slightly depending on the vaccine used, they generally fell within the same range. Cost-effectiveness of HPV vaccination was found to be most dependent on vaccine cost and duration of vaccine immunity, but not on the type of vaccine

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

[Purpose] The purpose of this study was to examine the effects of cervical traction treatment, cranial rhythmic impulse treatment, a manual therapy, and McKenzie exercise, a dynamic strengthening exercise, on patients who have the neck muscle stiffness of the infrequent episodic tension-type (IETTH) headache and frequent episodic tension-type headache(FETTH), as well as to provide the basic materials for clinical interventions. [Subjects] Twenty-seven subjects (males: 15, females: 12) who were diagnosed with IETTH and FETTH after treatment by a neurologist were divided into three groups: (a cervical traction group (CTG, n=9), a cranial rhythmic contractiongroup (CRIG, n=9), and a McKenzie exercise group (MEG, n=9). An intervention was conducted for each group and the differences in their degrees of neck pain and changes in muscle tone were observed. [Results] In the within-group comparison of each group, headache significantly decreased in CTG. According to the results of the analysis of the muscle tone of the upper trapezius, there was a statistically significant difference in MEG on the right side and in CRIG on the left side. According to the results of the analysis of the muscle tone of the sternocleidomastoid muscle, there was a statistically significant difference in MEG on the right side and in CRIG on the left side. [Conclusion] In the comparison of the splenius capitis muscle between the groups, there was a statistically significant difference on the right side. Hence, compared to the other methods, cervical traction is concluded to be more effective at reducing headaches in IETTH and FETTH patients.

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

Methods for evaluating cervical range of motion in trauma settings

Directory of Open Access Journals (Sweden)

Voss Sarah

2012-08-01

Full Text Available Abstract Immobilisation of the cervical spine is a common procedure following traumatic injury. This is often precautionary as the actual incidence of spinal injury is low. Nonetheless, stabilisation of the head and neck is an important part of pre-hospital care due to the catastrophic damage that may follow if further unrestricted movement occurs in the presence of an unstable spinal injury. Currently available collars are limited by the potential for inadequate immobilisation and complications caused by pressure on the patient’s skin, restricted airway access and compression of the jugular vein. Alternative approaches to cervical spine immobilisation are being considered, and the investigation of these new methods requires a standardised approach to the evaluation of neck movement. This review summarises the research methods and scientific technology that have been used to assess and measure cervical range of motion, and which are likely to underpin future research in this field. A systematic search of international literature was conducted to evaluate the methodologies used to assess the extremes of movement that can be achieved in six domains. 34 papers were included in the review. These studies used a range of methodologies, but study quality was generally low. Laboratory investigations and biomechanical studies have gradually given way to methods that more accurately reflect the real-life situations in which cervical spine immobilisation occurs. Latterly, new approaches using virtual reality and simulation have been developed. Coupled with modern electromagnetic tracking technology this has considerable potential for effective application in future research. However, use of these technologies in real life settings can be problematic and more research is needed.

Full Text Available Necrotizing fasciitis is a severe and potentially fatal soft tissue infection, but involvement of the head and neck is rare. We report on 4 cases of cervical necrotizing fasciitis arising from tonsillitis. One patient was diabetic and one had received steroids before disease development. One patient developed acute respiratory failure and died of septic shock. Three patients recovered, helped by early recognition, aggressive surgical intervention, appropriate broad-spectrum antibiotics, and supportive therapy. The common bacteria found in all abscess samples were Streptococcus sp., but mixed flora with anaerobic organisms was seen in all but 1 case. Tonsillitis and peritonsillar abscess must be suspected as a cause of cervical necrotizing fasciitis and a successful result can be achieved with immediate aggressive treatment.A fasceite necrotizante cervical é uma infecção grave de partes moles do pescoço. Trata-se de entidade rara, porém quando presente tem como principal origem um foco infeccioso odontogênico.

Um dos pacientes era portador de Diabetes Melittus não insulino- dependente e outro paciente havia recebido corticoterapia antes do desenvolvimento da infecção. Em um dos casos ocorreu mediastinite, insuficiência respiratória e o paciente evolui para o óbito em decorrência de choque séptico. Durante o tratamento, 3 pacientes evoluíram satisfatoriamente devido ao diagnostico precoce, tratamento cirúrgico agressivo e utilização de antibiótico terapia de largo espectro. A bactéria mais comumente encontrada foi o Streptococcus sp, mas flora mista com germes anaeróbios foi encontrada em 3 dos casos descritos. CONCLUSÕES: Deve-se suspeitar de tonsilite e abscesso peritonsilar como causa de fasceite necrotizante cervical para que tratamento agressivo e

Full Text Available Making an accurate diagnosis of tuberculous cervical lymphadenitis (TCL has been a problem to clinicians because it is a versatile masquerader and is often confused with lymphomas or cervical metastases. Ultrasound (US has advantages over other examination modalities in that it is noninvasive, inexpensive, time-saving, and able to guide procedures such as fine-needle aspiration and core-needle biopsy. It is increasingly being recognized as a primary tool for the evaluation of cervical lymph nodes. In this article, we present six cases with microscopically and/or pathologically confirmed TCL and illustrate the US features. A literature review was also conducted. The key US features of TCL include hypoechogenecity, strong internal echoes, echogenic thin layers, nodal matting, soft tissue changes, and displaced hilar vascularity. US is a reliable and effective tool in assessing cervical lymphadenopathies. When TCL is suspected under US, US-guided procedures such as fine-needle aspiration or core-needle biopsy can be conducted concomitantly to obtain the microscopic or pathological proof.

Review article. To review the indications, operative strategy, and complications of revision cervical spine reconstruction. With many surgeons expanding their indications for cervical spine surgery, the number of patients being treated operatively has increased. Unfortunately, the number of patients requiring revision procedures is also increasing, but very little literature exists reviewing changes in the indications or operative planning for revision reconstruction. Narrative and review of the literature. In addition to the well-accepted indications for primary cervical spine surgery (radiculopathy, myelopathy, instability, and tumor), we have used the following indications for revision surgery: pseudarthrosis, adjacent segment degeneration, inadequate decompression, iatrogenic instability, and deformity. Our surgical goal for pseudarthrosis is obviously to obtain a fusion, which can usually be performed with an approach not done previously. Our surgical goals for instability and deformity are more complex, with a focus on decompression of any neurologic compression, correction of deformity, and stability. Revision cervical spine reconstruction is safe and effective if performed for the appropriate indications and with proper planning.

Full Text Available Background: Women’s beliefs are one of the main reasons for not undergoing Pap-test for cervical cancer prevention. Health education programs could help change these beliefs and motivate women to adopt a preventive health behavior.Objectives: This study aims to assess the modification in women’s beliefs and behavior about cervical cancer prevention after the implementation of a health education intervention.Methodology: A health education intervention for cervical cancer prevention was implemented to 300 women in two prefectures of southern Greece. The experimental group received a 120-minute health education intervention, based on the Health Beliefs Model (HBM including a lecture, discussion and leaflets. The hypotheses were a will this brief intervention change women’s beliefs (perceived susceptibility to cervical cancer, benefits and barriers ofundergoing the Pap-test? b will this change in beliefs sustain in six months follow-up period? and c will women undergo pap-test in six months period? The women filled in an anonymous questionnaire, based on the Health Belief Model (HBM, before, immediately after and six months after the program.Results: The health education intervention significantly modified women’s beliefs and behaviors towards pap-test. The greater changes in women’s beliefs were observed in their sense of susceptibility towards the disease and the benefits of prevention which were sustained or improved after six months. Perceived barriers to undergo the Paptest, pain, embarrassment, and worry for the results decreased immediately after the program but started relapsingin the six month follow up period. Moreover, 88.1% of the women answered that they had underwent a Pap-test during the following six months.Conclusions: This health education intervention modified women’s beliefs and behavior about cervical cancer prevention. Short, low cost, health education interventions for breast cancer prevention to women can be

Purpose Cervical cancer screening is an effective method for reducing the incidence and mortality of cervical cancer, but the screening attendance rate in developing countries is far from satisfactory, especially in rural areas. Wufeng is a region of high cervical cancer incidence in China. This study aimed to investigate the issues that concern cervical cancer and screening and the factors that affect women’s willingness to undergo cervical cancer screening in the Wufeng area. Participants and Methods A cross-sectional survey of women was conducted to determine their knowledge about cervical cancer and screening, demographic characteristics and the barriers to screening. Results Women who were willing to undergo screenings had higher knowledge levels. “Anxious feeling once the disease was diagnosed” (47.6%), “No symptoms/discomfort” (34.1%) and “Do not know the benefits of cervical cancer screening” (13.4%) were the top three reasons for refusing cervical cancer screening. Women who were younger than 45 years old or who had lower incomes, positive family histories of cancer, secondary or higher levels of education, higher levels of knowledge and fewer barriers to screening were more willing to participate in cervical cancer screenings than women without these characteristics. Conclusion Efforts are needed to increase women’s knowledge about cervical cancer, especially the screening methods, and to improve their perceptions of the screening process for early detection to reduce cervical cancer incidence and mortality rates.

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.

Science.gov (United States)

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.

To investigate whether the concomitant presence of anterior cervical osteophytes can influence the severity and outcome of patients with poststroke dysphagia. Retrospective case-control study. Hospital. A total of 40 participants were identified (N=40). Patients with poststroke dysphagia with anterior cervical osteophytes (n=20) were identified and matched by age, sex, location, and laterality of the stroke lesion to a poststroke dysphagia control group with no anterior cervical osteophytes (n=20). Not applicable. Videofluoroscopic swallowing study, Functional Oral Intake Scale (FOIS), and Penetration-Aspiration Scale results assessed within the first month of stroke were analyzed. The FOIS at 6 months was recorded, and severity of dysphagia was compared between the 2 groups. The case group had larger degrees of postswallow residues in the valleculae and pyriform sinuses (P=.020 and Pdysphagia (OR=15.375; 95% CI, 3.195-infinity). The presence of anterior cervical osteophytes, which may cause mechanical obstruction and interfere with residue clearance at the valleculae and pyriform sinuses and result in more postswallow aspiration, may influence initial severity and outcome of poststroke dysphagia. The presence of anterior cervical osteophytes may be considered an important clinical condition that may affect poststroke dysphagia rehabilitation.

Rey, Diego; Angel, David; Oberti, Giovanni; Baccetti, Tiziano

2008-03-01

In this cephalometric investigation, we compared the treatment and posttreatment effects on patients undergoing an initial phase of mandibular cervical headgear (MCH) therapy followed later by comprehensive edgewise therapy with untreated Class III controls. The treated sample consisted of 21 patients treated consecutively with MCH before the pubertal growth spurt (average age, 10 years 2 months at the beginning of treatment). At the final observation period (average age, 15 years 3 months), all patients were in decelerative growth phases as determined by the cervical vertebral maturation method. Active treatment and posttreatment effects were evaluated in the treated group with nonparametric statistical analysis for paired samples. The treated sample was compared with a nonparametric statistical test for independent samples with 20 untreated Class III subjects who were matched for malocclusion, sex, and stage of cervical vertebral maturation to the treatment group. MCH therapy followed by fixed appliances was shown to be an effective treatment for the correction of skeletal Class III malocclusion at postpubertal observation. The favorable skeletal effects consisted mainly of smaller increases in mandibular length and advancement with respect to the controls, with the final outcome of significant improvements in the sagittal skeletal (+4 mm for the Wits appraisal) and dental (+2.7 mm for overjet, -4.4 mm for molar relationship) parameters. This treatment protocol also induced significant downward rotation of the mandible (2.8 degrees ).

Cervical radiculopathy (CR) is a disease of the cervical spine and a space-occupying lesion that occurs because of pathological problems with cervical nerve roots. Nerve root injury to produce functional disability. The purpose of this study was to examine the effects of neural mobilization with manual cervical traction (NMCT) compared with manual cervical traction (MCT) on pain, functional disability, muscle endurance, and range of motion (ROM) in individuals with CR patients. A blinded randomized clinical trial was conducted. Thirty CR patients were divided into two groups - those who received NMCT and those who received MCT. The intervention was applied three times per week for eight weeks. It was measured in order to determine the pain and functional disability in patients with CR. The numeric pain rating scale (NPRS), neck disability index (NDI), ROM, and deep flexor endurance of patients were measured prior to the experiment, four weeks, and eight weeks after the experiment to compare the time points. A repeated-measures analysis of variance was used to compare differences within each group prior to the experiment. And Bonferroni test was performed to examine the significance of each time point. There were significant differences within each group prior to the intervention, four weeks after the intervention, and eight weeks after the intervention in NPRS, NDI, ROM, and deep flexor endurance (Ppain relief, recovery from neck disability, ROM, and deep flexor endurance for patients with CR.

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. 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. 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). 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.

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

1988-08-15

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

To investigate the "window" surgical exposure strategy of the upper anterior cervical retropharyngeal approach for the exposure and decompression and instrumentation of the upper cervical spine. From Jan. 2000 to July 2008, 5 patients with upper cervical spinal injuries were treated by surgical operation included 4 males and 1 female with and average age of 35 years old ranging from 16 to 68 years. There were 2 cases of Hangman's fractures (type II ), 2 of C2.3 intervertebral disc displacement and 1 of C2 vertebral body tuberculosis. All patients underwent the upper cervical anterior retropharyngeal approach through the "window" between the hypoglossal nerve and the superior laryngeal nerve and pharynx and carotid artery. Two patients of Hangman's fractures underwent the C2,3 intervertebral disc discectomy, bone graft fusion and internal fixation. Two patients of C2,3 intervertebral disc displacement underwent the C2,3 intervertebral disc discectomy, decompression bone graft fusion and internal fixation. One patient of C2 vertebral body tuberculosis was dissected and resected and the focus and the cavity was filled by bone autografting. C1 anterior arch to C3 anterior vertebral body were successful exposed. Lesion resection or decompression and fusion were successful in all patients. All patients were followed-up for from 5 to 26 months (means 13.5 months). There was no important vascular and nerve injury and no wound infection. Neutral symptoms was improved and all patient got successful fusion. The "window" surgical exposure surgical technique of the upper cervical anterior retropharyngeal approach is a favorable strategy. This approach strategy can be performed with full exposure for C1-C3 anterior anatomical structure, and can get minimally invasive surgery results and few and far between wound complication, that is safe if corresponding experience is achieved.

A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately. This synthesis of the literature on radiation therapy for cervical cancer is based on data from 1 meta-analysis and 34 randomized trials. In total, 35 scientific articles are included, involving 7,952 patients. The results were compared with those of a similar overview from 1996 including 34,024 patients. The conclusions reached can be summarized in these points: There are limited scientific data supporting that postoperative pelvic radiotherapy improves disease-free survival in early cervical cancer. No firm conclusion can be drawn. There is moderate scientific evidence that external beam radiotherapy combined with brachytherapy gives a similar disease-free and overall survival rate as radical hysterectomy in early cervical cancer. There is strong scientific evidence that concomitant radiochemotherapy improves disease-free and overall survival compared to radiotherapy alone in early cervical cancer. The NCI has recently published an announcement stating that cisplantin-based chemotherapy should be used concomitantly with radiotherapy in cervical cancer. No solid documentation for this statement can be found concerning locally advanced stages (>IIB). There is a strong scientific evidence that cisplatin-based chemotherapy given concomitantly with radiotherapy is superior to concomitant chemotherapy with hydroxyurea. There is no scientific evidence to show that neoadjuvant chemotherapy followed by radiotherapy improves disease-free or overall survival compared to radiotherapy alone in patients with localized cervical cancer. There is moderate scientific evidence that high-dose-rate brachytherapy gives the same local control rate as low-dose-rate brachytherapy but with fewer rectal complications.

Combining antitumor agents with bioactive compounds is a potential strategy for improving the effect of chemotherapy on cancer cells. The goal of this study was to elucidate the antitumor effect of the flavonoid, fisetin, combined with the multikinase inhibitor, sorafenib, against human cervical cancer cells in vitro and in vivo. The combination of fisetin and sorafenib synergistically induced apoptosis in HeLa cells, which is accompanied by a marked increase in loss of mitochondrial membrane potential. Apoptosis induction was achieved by caspase-3 and caspase-8 activation which increased the ratio of Bax/Bcl-2 and caused the subsequent cleavage of PARP level while disrupting the mitochondrial membrane potential in HeLa cells. Decreased Bax/Bcl-2 ratio level and mitochondrial membrane potential were also observed in siDR5-treated HeLa cells. In addition, in vivo studies revealed that the combined fisetin and sorafenib treatment was clearly superior to sorafenib treatment alone using a HeLa xenograft model. Our study showed that the combination of fisetin and sorafenib exerted better synergistic effects in vitro and in vivo than either agent used alone against human cervical cancer, and this synergism was based on apoptotic potential through a mitochondrial- and DR5-dependent caspase-8/caspase-3 signaling pathway. This combined fisetin and sorafenib treatment represents a novel therapeutic strategy for further clinical developments in advanced cervical cancer.

Cervicogenic dizziness is a disabling condition commonly associated with cervical dysfunction. Although the growing interest with the importance of normal sagittal configuration of cervical spine, the missing component in the management of cervicogenic dizziness might be altered structural alignment of the cervical spinal region itself. To investigate the immediate and long-term effects of a 1-year multimodal program, with the addition of cervical lordosis restoration and anterior head translation (AHT) correction, on the severity of dizziness, disability, cervicocephalic kinesthetic sensibility, and cervical pain in patients with cervicogenic dizziness. A randomized controlled study with a 1 year and 10 weeks' follow-up. University research laboratory. Seventy-two patients (25 female) between 40 and 55 years with cervicogenic dizziness, a definite hypolordotic cervical spine and AHT posture were randomly assigned to the control or an experimental group. Both groups received the multimodal program; additionally, the experimental group received the Denneroll™ cervical traction. Outcome measures included AHT distance, cervical lordosis, dizziness handicap inventory (DHI), severity of dizziness, dizziness frequency, head repositioning accuracy (HRA) and cervical pain. Measures were assessed at three time intervals: baseline, 10 weeks, and follow-up at 1 year and 10 weeks. Significant group × time effects at both the 10 week post treatment and the 1-year follow-up were identified favoring the experimental group for measures of cervical lordosis (Ppain intensity, and HRA; DHI scale (P=0.5), severity of dizziness (P=0.2), dizziness frequency (P=0.09), HRA (P=0.1) and neck pain (P=0.3). At 1-year follow-up, the between-group analysis identified statistically significant differences for all of the measured variables including anterior head translation (2.4 cm [-2.3;-1.8], Pcervical lordosis (-14.4° [-11.6;-8.3], Ppain (4.97 [-5.3;-4.3], Pcervical extension traction to

To review the relevant literature on cervical facet joint dysfunction and determine findings regarding its anatomy, etiology, prevalence, clinical features, diagnosis, and treatment. A computer-aided search of several databases was performed, including Medline (1966 to present), Ovid (1966 to present), and the Cochrane database (1993 to present). Selected articles had the following criteria: (1) all articles analyzed cervical facet joint pain-anatomy, prevalence, etiology, diagnosis, treatment; (2) only full, published articles were studied, not abstracts; and (3) all articles were published in English. All articles were critically evaluated and included the following categories: randomized controlled trials, meta-analyses, uncontrolled clinical trials, uncontrolled comparison studies, nonquantitative systematic reviews, and literature-based reviews. We examined 45 references that consisted of 44 journal articles and relevant sections from 1 textbook. Cervical facet joints have been well established in the literature as a common nociceptive pain generator, with an estimated prevalence that ranges from 25% to 66% of chronic axial neck pain. No studies have reported clinical examination findings that are diagnostic for cervical facet mediated pain. Overall the literature provides very limited information regarding the treatment of this condition, with only radiofrequency neurotomy showing evidence of effectively reducing pain from cervical facet joint dysfunction.

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

Purpose: Worldwide, particularly in developing countries, many women present with advanced stage cervical cancer for which palliative radiotherapy is the treatment of choice or may be the only available treatment. The purpose of this study was to determine from the literature the optimal palliative radiation scheme for the treatment of advanced cervical cancer. Design: A systematic literature review up to January 2010 was performed in Medline, Embase, the Cochrane database, CinHL and Google Scholar using a combination of synonyms for: cervical cancer, palliative treatment and radiation therapy. No limitations were applied for language or study types. For included papers data were extracted and described. Results: Only eight papers were identified and none compared the results of different fractionation schemes. Most used observational retrospective study design with considerable sources of bias. No studies used validated endpoints for symptom relief nor did they include measures of the quality of life. Several papers described the experience with single or multiple monthly 10 Gy doses or with a higher total dose delivered in 2-4 fractions within 48 h to 1 week. Studies report varying amounts of relief from bleeding. The effect on other symptoms such as pain and discharge is not evaluable. Acute and late toxicity is poorly documented. Conclusion: There is a dearth of information in the current literature to guide selection of an optimal palliative radiation schedule for treatment of patients with advanced cervical cancer. Based on this review and information from other solid tumors, there is no evidence to support the common belief that better and longer palliation is achieved with a high dose delivered in multiple smaller fractions. There is a clear need for comparative studies of different radiation fractionation schedules in order to identify an optimal palliative radiation scheme. These studies require the use of validated endpoints to measure specific symptom

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

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

Current cervical total disc replacement (TDR) designs incorporate a variety of different biomaterials including polyethylene, stainless steel, titanium (Ti), and cobalt-chrome (CoCr). These materials are most important in their utilization as bearing surfaces which allow for articular motion at the disc space. Long-term biological effects of implanted materials include wear debris, host inflammatory immune reactions, and osteolysis resulting in implant failure. We review here the most common materials used in cervical TDR prosthetic devices, examine their bearing surfaces, describe the construction of the seven current cervical TDR devices that are approved for use in the United States, and discuss known adverse biological effects associated with long-term implantation of these materials. It is important to appreciate and understand the variety of biomaterials available in the design and construction of these prosthetics and the considerations which guide their implementation.

To explore the effect of clinical application of stand-alone MC+PEEK cage in anterior cervical fusion. From January 2011 to January 2014,50 patients were treated with the MC+PEEK cage filled with autogenous cancellous illic-bone graft after anterior cervical discectomy. There were 22 patients with cervical spondylosis,26 patients with traumatic cervical disc herniation, 2 patients with cervical instability in these patients. There were 32 males and 18 females, aged from 30 to 79 years old with an average of 53.30 years old. There were 32 patients with single segment, 15 patients with double segments and 3 patients with three segments. Cervical AP and lateral and the flexion-extension X-rays were regularly taken in order to assess the cervical physiological curvature, the graft fusion and internal fixation related complications. Nerve function, clinical effect and bone fusion were respectively evaluated according to Japan Orthopedic Association (JOA), Otani grade and Suk method. All patients were followed up from 6 to 36 months with an average of 20 months. No correlated surgical complications were found and all patients obtained bony fusion with an average time of 4.30 months. JOA score had significantly improvement after surgery (P cervical fusion can obtain satisfactory clinical effect with less operation injury and reduce the complications. It is a better fusion method in anterior cervical fusion.

Cervical cancer is the leading cause of cancer death among women in El Salvador. Utilizing data from the Cervical Cancer Prevention in El Salvador (CAPE) demonstration project, we assessed the health and economic impact of HPV-based screening and two different algorithms for the management of women who test HPV-positive, relative to existing Pap-based screening. We calibrated a mathematical model of cervical cancer to epidemiologic data from El Salvador and compared three screening algorithms for women aged 30-65 years: (i) HPV screening every 5 years followed by referral to colposcopy for HPV-positive women (Colposcopy Management [CM]); (ii) HPV screening every 5 years followed by treatment with cryotherapy for eligible HPV-positive women (Screen and Treat [ST]); and (iii) Pap screening every 2 years followed by referral to colposcopy for Pap-positive women (Pap). Potential harms and complications associated with overtreatment were not assessed. Under base case assumptions of 65% screening coverage, HPV-based screening was more effective than Pap, reducing cancer risk by ∼ 60% (Pap: 50%). ST was the least costly strategy, and cost $2,040 per year of life saved. ST remained the most attractive strategy as visit compliance, costs, coverage, and test performance were varied. We conclude that a screen-and-treat algorithm within an HPV-based screening program is very cost-effective in El Salvador, with a cost-effectiveness ratio below per capita GDP. © 2015 UICC.

Objective: To investigate the frequency and effective treatment of ulcers and sinuses in cases of tuberculous cervical lymphadenitis (TCL). Patients and Methods: A hundred cases of histopathologically confirmed cases of tuberculous cervical lymphadenitis of more than six weeks of duration were included in the study. Overall frequency of the complication as well as the efficacy of treatment regime was considered. Results: Out of 100 patients, 8 (8%) were found to develop ulcers and/or sinuses during the process of development of TCL which were effectively treated (100% cure rate). Mode of treatment was surgical excision of ulcers/sinuses along with affected underlying lymph nodes, followed by short course of anti-tubercular chemotherapy. Not a single case recurred during their follow-up period. Conclusion: In this series there was a low frequency of formation of ulcers/sinuses during the process of development of TCL. Surgical excision of ulcers/sinuses along with affected underlying lymph nodes, followed by short course of anti-tubercular chemotherapy is the effective methods of their treatment. (author)

The present work discusses effect of infrared (IR) femtosecond laser irradiation on neoplasm of white mice with experimental cervical cancer- 5 (CC-5 on the 20th and 30th days after tumor transplantation). Tumor tissue was irradiated by femtosecond erbium doped fiber laser: the wavelength is 1.55 μm, average and peak powers are1,25 mW and 6kW, respectively, irradiation trials n=10. The average energy density (energy dose) on a tissue for two groups of animals was 0,24 J/cm2 and 0,36 J/cm2 for a single trial. Irradiation was followed by biochemical determination of LPO AOS parameters ("Lipid peroxidation-antioxidants" system): malondialdehyde (MDA), activity of superoxide dismutase (SOD), catalase and glutathione-reductase (GR), glutathione-S-transferase (GST). A subsequent morphological study of tumor tissue was performed. Mathematical analysis of data demonstrates a weak dependence of the studied parameters on energy dose. The latter implies the trigger effect of IR femtosecond laser irradiation on redox-dependent processes in neoplasm at experimental cervical cancer.

Cervical insufficiency is characterized by premature, progressive dilation and shortening of the cervix during pregnancy. If left unattended, this can lead to the prolapse and rupture of the amniotic membrane, which usually results in midtrimester pregnancy loss or preterm birth. Previous studies have shown that proinflammatory cytokines such as interleukin-1β, interleukin-6, interleukin-8, and tumor necrosis factor alpha are up-regulated in normal parturition but are also associated with preterm birth. Studies evaluating such markers in patients with cervical insufficiency have evaluated only their diagnostic potential. Even fewer studies have studied them within the context of cerclage surgery. The objective of the study was to evaluate the impact of local and systemic inflammatory markers on the pathogenesis of cervical insufficiency and the effect of cerclage surgery on the local immune microenvironment of women with cervical insufficiency. We recruited 28 pregnant women (12-20 weeks' gestation) diagnosed with insufficiency and referred for cerclage surgery and 19 gestational age-matched normal pregnant women as controls. Serum and cervicovaginal fluid samples were collected before and after cerclage surgery and during a routine checkup for normal women and analyzed using a targeted 13-plex proinflammatory cytokine assay. Before surgery, patients with cervical insufficiency had higher levels of interleukin-1β, interleukin-6, interleukin-12, monocyte chemoattractant protein-1 and tumor necrosis factor alpha in cervicovaginal fluid compared to controls, but after surgery, these differences disappeared. No differences were found in serum of insufficiency versus control women. In patients with insufficiency, the levels of interleukin-1β, interleukin-6, interleukin-8, monocyte chemoattractant protein-1, and interferon gamma in cervicovaginal fluid declined significantly after cerclage compared with before intervention, but these changes were not detected in serum

2018-05-23

Targeting mitochondrial respiration has been documented as an effective therapeutic strategy in cancer. However, the impact of mitochondrial respiration inhibition on cervical cancer cells are not well elucidated. Using a panel of cervical cancer cell lines, we show that an existing drug atovaquone is active against the cervical cancer cells with high profiling of mitochondrial biogenesis. Atovaquone inhibited proliferation and induced apoptosis with varying efficacy among cervical cancer cell lines regardless of HPV infection, cellular origin and their sensitivity to paclitaxel. We further demonstrated that atovaquone acts on cervical cancer cells via inhibiting mitochondrial respiration. In particular, atovaquone specifically inhibited mitochondrial complex III but not I, II or IV activity, leading to respiration inhibition and energy crisis. Importantly, we found that the different sensitivity of cervical cancer cell lines to atovaquone were due to their differential level of mitochondrial biogenesis and dependency to mitochondrial respiration. In addition, we demonstrated that the in vitro observations were translatable to in vivo cervical cancer xenograft mouse model. Our findings suggest that the mitochondrial biogenesis varies among patients with cervical cancer. Our work also suggests that atovaquone is a useful addition to cervical cancer treatment, particularly to those with high dependency on mitochondrial respiration. Copyright © 2018 Elsevier Inc.

The majority of studies examining the role of cervical muscles on head-neck kinematics focused on musculoskeletal attributes (e.g. strength). Cervical neuromuscular response to perturbation may represent a divergent construct that has not been examined under various perturbation conditions. This study examined the association between cervical musculoskeletal attributes and cervical neuromuscular response of the sternocleidomastoid (SCM) to perturbation. Furthermore, this study examined the effect of anticipation and preload on the SCM neuromuscular response. Nineteen participants completed measurement of SCM muscle size, cervical flexion maximal voluntary isometric contraction, and the neuromuscular response of the SCM to cervical perturbation. Cervical perturbation was delivered by dropping a 1.59 kg mass from a loading apparatus. The impulsive load was delivered under four conditions: (1) Anticipated perturbation with no preload (A-NP), (2) Unanticipated perturbation with no preload (U-NP), (3) Anticipated perturbation with preload (A-P), and (4) Unanticipated perturbation with preload (U-P). None of the cervical musculoskeletal attributes were correlated with the SCM cervical neuromuscular response. This study demonstrated significant effect of preloading and anticipation on baseline EMG amplitude and EMG onset latency for the SCM. Furthermore, there was a significant effect of preloading on average EMG response amplitude for the SCM. The findings of this study indicate that cervical neuromuscular response of the SCM is different from musculoskeletal attributes and is influenced by perturbation conditions. These findings provide conceptual support to examine the neuromuscular response of the SCM in mitigating head-neck kinematics. Copyright © 2018 Elsevier Ltd. All rights reserved.

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.

Ultrasound Guided Nerve Root Injection in Patients with Cervical Spondylytic Radicular Pain

Directory of Open Access Journals (Sweden)

LT Choong

2009-05-01

Full Text Available Selective cervical nerve root injection using a mixture of corticosteroid and lignocaine is a treatment option for managing cervical radiculopathic pain. The procedure is usually performed under image guided fluoroscopy or Computerized Tomograhy. Ultrasound-guided cervical nerve root block does not expose the patients and personnel to radiation. During injection, the fluid is mostly visualized in a real-time fashion. This retrospective study reviewed the effectiveness of ultrasound in guiding cervical peri-radicular injection for pain relief in patients with recalcitrant cervical radiculopathy. There were no complications reported in this series.

de Sanjosé, S; Bosch, F X; Muñoz, N; Shah, K

1997-01-01

In this chapter we first describe the variation of cervical cancer in relation to social class. Thereafter we examine the causes for the occurrence of socioeconomic differences in invasive cervical cancer, using data from two case-control studies carried out in Colombia and Spain. Cervical cancer is the most common cancer in developing countries and the sixth most common in developed countries. In all areas, it is more frequent among women of low socioeconomic status, it is associated with multiple sexual partners and early age at first sexual intercourse, and both incidence and mortality are reduced by screening. According to population-based surveys in industrialized countries, men of low socioeconomic status report fewer sexual partners than men of high socioeconomic status but there is no clear indication that the same is true of women of low socioeconomic status. In the case-control studies in Spain and Colombia, the human papillomavirus and all other sexually transmitted diseases were more prevalent among women in low socioeconomic strata. Number of sexual partners and particularly contacts with prostitutes were higher among husbands of women of low socioeconomic status. Other potential risk factors for the disease, such as smoking and oral contraceptive use, and also cervical cancer screening (Pap smears), were more common in women of high social strata. Women with no schooling had a threefold higher risk in Spain and a fivefold higher risk in Colombia of having cervical cancer compared with women who had achieved a higher educational level. After adjustment for sexual behaviour, HPV DNA status, history of Pap smears and husband's contact with prostitutes, this association was considerably reduced. These results are indicative that socioeconomic differences in the incidence of cervical cancer can be partly explained by differences in the prevalence of HPV DNA. Men's sexual behaviour and particularly contacts with prostitutes might be a major contributor to

Full Text Available Background HPV-test is more effective than Pap test in preventing cervical cancer. HPV-based screening will imply longer intervals and a triage test for HPV positive women. It will also permit the use of self-sampling devices. These innovations may affect population coverage, participation, and compliance to protocols, and likely in a different way for less educated, poorer, and disadvantaged women. Aim To describe the impact on inequalities, actual or presumed, of the introduction of HPV-based screening. Methods The putative HPV-based screening algorithm has been analysed to identify critical points for inequalities. A systematic review of the literature has been conducted searching PubMed on HPV screening coverage, participation, and compliance. Results were summarised in a narrative synthesis. Results Knowledge about HPV and cervical cancer was lower in women with low Socio-economic status and in disadvantaged groups. A correct communication can reduce differences. Longer intervals will make it easier to achieve high-population coverage, but higher cost of the test in private providers could reduce the use of opportunistic screening by disadvantaged women. There are some evidences that inviting for HPV test instead of Pap increases participation, but there are no data on social differences. Self-sampling devices are effective in increasing participation and coverage. Some studies showed that the acceptability of self-sampling is higher in more educated women, but there is also an effect on hard-to-reach women. Communication of HPV positivity may increase anxiety and impact on sexual behaviours, the effect is stronger in low educated and disadvantaged women. Many studies found indirect evidence that unvaccinated women are or will be more probably under-screened. Conclusions The introduction of HPV test may increase population coverage, but non-compliance to protocols and interaction with opportunistic screening can increase existing

2015-01-01

Full Text Available Current cervical total disc replacement (TDR designs incorporate a variety of different biomaterials including polyethylene, stainless steel, titanium (Ti, and cobalt-chrome (CoCr. These materials are most important in their utilization as bearing surfaces which allow for articular motion at the disc space. Long-term biological effects of implanted materials include wear debris, host inflammatory immune reactions, and osteolysis resulting in implant failure. We review here the most common materials used in cervical TDR prosthetic devices, examine their bearing surfaces, describe the construction of the seven current cervical TDR devices that are approved for use in the United States, and discuss known adverse biological effects associated with long-term implantation of these materials. It is important to appreciate and understand the variety of biomaterials available in the design and construction of these prosthetics and the considerations which guide their implementation.

Nelfinavir is effective against human cervical cancer cells in vivo: a potential treatment modality in resource-limited settings

Full Text Available Mitzie-Ann Davis,* Joe R Delaney,* Chandni B Patel, Ryan Storgard, Dwayne G Stupack Division of Gynecologic Oncology, Department of Reproductive Medicine, Rebecca and John UCSD Moores Cancer Center, La Jolla, CA, USA *These authors contributed equally to this work Objective: The standard treatment for cervical cancer in developed countries includes surgery and chemoradiation, with standard of care lagging in developing countries. Even in the former case, treatment frequently yields recalcitrant tumors and women succumb to disease. Here we examine the impact of nelfinavir, an off-patent viral protease inhibitor, which has shown promise as an antineoplastic agent. Methods: We evaluated the morphological and proliferative effects of the autophagy-stressing drug nelfinavir in normal and cisplatin-resistant cervical cancer cells. Immunofluorescent validation of autophagy markers was performed and the impact of nelfinavir in an in vivo model of tumor growth was determined. Results: Nelfinavir exhibits cytotoxicity against both cisplatin-sensitive and -resistant ME-180 human cervical cancer cells in vitro and in vivo. Immunoblotting and immunofluorescence showed an expression of the autophagy marker LC3-II in response to nelfinavir treatment. Conclusion: Nelfinavir, now available as an inexpensive generic orally dosed agent (Nelvir, is cytotoxic against cervical cancer cells. It acts by burdening the autophagy pathway to impair tumor cell survival and a modest induction of apoptosis. While further studies are needed to elucidate the optimal method of application of nelfinavir, it may represent an appealing global option for the treatment of cervical cancer. Keywords: cervical cancer, nelfinavir, cisplatin resistance, autophagy, responsible medicine

Kampusch, Stefan; Kaniusas, Eugenijus; Széles, Jozsef C

2015-10-01

Primary cervical dystonia is characterized by abnormal, involuntary, and sustained contractions of cervical muscles. Current ways of treatment focus on alleviating symptomatic muscle activity. Besides pharmacological treatment, in severe cases patients may receive neuromodulative intervention such as deep brain stimulation. However, these (highly invasive) methods have some major drawbacks. For the first time, percutaneous auricular vagus nerve stimulation (pVNS) was applied in a single case of primary cervical dystonia. Auricular vagus nerve stimulation was already shown to modulate the (autonomous) sympathovagal balance of the body and proved to be an effective treatment in acute and chronic pain, epilepsy, as well as major depression. pVNS effects on cervical dystonia may be hypothesized to rely upon: (i) the alteration of sensory input to the brain, which affects structures involved in the genesis of motoric and nonmotoric dystonic symptoms; and (ii) the alteration of the sympathovagal balance with a sustained impact on involuntary movement control, pain, quality of sleep, and general well-being. The presented data provide experimental evidence that pVNS may be a new alternative and minimally invasive treatment in primary cervical dystonia. One female patient (age 50 years) suffering from therapy refractory cervical dystonia was treated with pVNS over 20 months. Significant improvement in muscle pain, dystonic symptoms, and autonomic regulation as well as a subjective improvement in motility, sleep, and mood were achieved. A subjective improvement in pain recorded by visual analog scale ratings (0-10) was observed from 5.42 to 3.92 (medians). Muscle tone of the mainly affected left and right trapezius muscle in supine position was favorably reduced by about 96%. Significant reduction of muscle tone was also achieved in sitting and standing positions of the patient. Habituation to stimulation leading to reduced stimulation efficiency was observed and

Objective: This study aimed to determine the effectiveness of an educational intervention to prevent cervical cancer among marginalized Iranianwomen based on the Protection Motivation Theory (PMT) as a theoretical framework. Methods: This quasi-experimental study was carried out on 143 women of Kermanshah City in western Iran during 2017. Participants were recruited through cluster and simple random sampling and randomly divided into experimental (n=72) and control groups (n=71). All completed a self-administered questionnaire including PMT constructs and demographic variables. An intervention over six sessions was then applied to the experimental group. Reassessment was conducted three months after the intervention, with data was analyzed with SPSS-16 using chi-square, McNemar, paired T- and independent T-tests. Results: The mean scores for the constructs of PMT, and cervical cancer screening behavior showed no significant differences between the two groups before the intervention (P>0.05). The educational manipulation had significant effects on the experimental groups’ average response for perceived vulnerability, perceived severity, perceived reward, self-efficacy, response efficacy, response cost and protection motivation (all p health centers were significantly increased after 3 months in the experimental (P=0.048), but notthe control group (P>0.05). Conclusions: The results show that applying an educational intervention based on PMT might help prevent cervical cancer and improve regular Pap smear testing. Creative Commons Attribution License

Pharmacokinetics of adriamycin vaginal suppository on uterine cervical cancer

Noda, Tsuneo; Kiyozuka, Yasuhiko; Katakami, Yoshiaki

1986-01-01

Vaginal suppositories of Adriamycin (ADM, 5 mg), for reducing the capacity for repair from sublethal damage of X-ray-irradiated cells, were prepared using Wipepsol S-55 as the vehicle, and were intravaginally administered to patients with advanced uterine cervical cancer, and their pharmacokinetics and clinical effects were studied. The ADM concentration in the uterine cervical cancer tissues indicated high levels (17 to 566 μg/g), and migration into the cardinal ligament and regional lymph nodes was noted. However, little ADM was detected in serum (0 to 0.14 μg/g), probably because of its molecular weight and excellent tissue absorbance, and no side effects, such as cardiotoxicity and myelosuppression due to consecutive administration were detected. Histologically, the effect obtained when administered alone was limited, administration in combination with radiotherapy being more effective. Accordingly, radiotherapy of advanced uterine cervical cancer with concomitant administration of ADM vaginal suppositories seems to bring about a more powerful antitumoral effect with fewer systemic side effects.

Mironov, A.M.

1979-01-01

The classical ways of subarachnoid puncture - lumbal and suboccipital - require a considerable quantity of air in performing segmental cervical pneumomyelography. An examination technique is described, based on the recently suggested lateral subarachnoid puncture within the interarcus space at C 1 -C 2 level. Emphasis is laid on the possibilities of carrying out various neuro-roentgenological studies through contrast medium introduction in the fashion described, namely: pontocerebellar cistemography and cervical myelography with AMIPAQUE - a water soluble contrast medium. On the basis of literature data and personal experience it is stated that the risk in lateral subarachnoid puncture is by no means higher than in suboccipital puncture. The main advantages of selective cervical myelography effected by contrast medium injection through lateral subarachnoid puncture include the possibility to perform investigation with a minimum amount of air (4-8 cm 3 ) and to study patients with fixed, direct skull fraction after Crutchfield under maximum sparing conditions.

Objective: To assess the clinical efficacy and complications of CT-guided percutaneous vertebroplasty in the treatment of metastases of the cervical spine, and to discuss the proper needle path for different cervical vertebra. Methods: CT-guided percutaneous vertebroplasty was performed in 17 patients with cervical vertebral metastatic neoplasm, and the results of the treatment were retrospectively analyzed. Close observation was carded out after the procedure and a follow-up of 3-17 months was conducted. A comparison of the visual analogue pain scale (VAS) and Frankel's classification between pre-and post- operation was made. The occurrence of complications was recorded. The optimal needle path was summarized. Results: (1) The successful puncture was achieved in all 17 cases. The needle pathway included: the front of carotid sheath (n=4), between carotid sheath and vertebral artery (n=11) and behind the vertebral artery and carotid sheath (n=2). (2) Before the procedure the VAS was 7.24 ± 1.01, and at the time of one hour, one week and three months after the procedure it was decreased to 3.24 ± 1.09, 2.40 ± 0.80 and 1.82 ± 0.53 respectively. Wilcoxon signed-rank test showed that the difference in VAS between pre-and post- operation was statistically significant (T=76.5, P 2 =4.52, P=0.033 and P<0.05 when Kruskal-Wallis test was adopted. (3) CT scanning immediately after the procedure showed that slight leakage of cement to the adjacent disc, epidural fat, parosteal tissue or to the needle path occurred in 35.3% with no serious complications. In a follow-up period of 3-17 months, the metastatic lesions remained stable in 14 cases (82.4%). Conclusion: (1) The optimal needle path for upper cervical vertebrae is posterolateral transpedicular approach while for the lower cervical vertebrae it is more reasonable to puncture via the front carotid sheath or between carotid sheath and vertebral artery. Nevertheless, the puncture pathway should be devised individually

To examine the effect that breast and/or cervical cancer screening programmes for ethnic minority women have on their knowledge of and beliefs about breast or cervical cancer and screening, and on their screening intentions and uptake rates. Recommendations are also made for the format and content of such programmes, based on existing evidence. A comprehensive literature search was carried out both manually and by means of five electronic databases. The findings are summarised and synthesised in narrative fashion. The ten RCTs included here were conducted among ethnic minority women in the United States or Canada, where breast or cervical cancer screening programmes have led to improvements in screening intentions, knowledge of cervical cancer and pap test uptake. The Breast Cancer Screening Belief Scale and self-reporting were the methods commonly used to measure outcomes. The shared characteristics of both countries' programmes were that they were theory- and language-based, the instruction took place in a community setting, the materials were culturally relevant, the content highlighted key messages about breast or cervical cancer and screening measures, and there were multiple intervention strategies. Breast or cervical cancer screening programmes in Western countries have demonstrated improvements in knowledge of the disease, screening intentions and pap test uptake, although evidence on the effectiveness of the interventions has been limited. The common characteristics of programmes are identified, but a comprehensive model is still needed to link these characteristics with other factors and mediators influencing outcomes.

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.

Cervical Vertigo: Historical Reviews and Advances.

Science.gov (United States)

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.

Focal Dystonia in Hemiplegic Upper Limb: Favorable Effect of Cervical Microsurgical DREZotomy Involving the Ventral Horn - A Report of 3 Patients.

Science.gov (United States)

Sindou, Marc; Georgoulis, George

2016-01-01

Focal dystonia in hemiplegic upper limbs is poorly responsive to medications or classical neurosurgical treatments. Only repeated botulinum toxin injections show efficacy, but in most severe cases effects are transient. Cervical DREZ lesioning, which has proven efficacious in hyperspasticity when done deeply (3-5 mm) in the dorsal horn, may have favorable effects on the dystonic component when performed down to, and including, the base of the ventral horn (5-6 mm in depth). Three patients underwent deep cervical microsurgical DREZotomy (MDT) for focal dystonia in the upper limb. Hypertonia was reduced, and sustained dystonic postures were suppressed. Residual motor function (hidden behind hypertonia) came to the surface. Cervical MDT may be a useful armamentarium for treating refractory focal dystonia in the upper limb. © 2016 S.

Karas, Steve; Olson Hunt, Megan J

2014-05-01

Randomized clinical trial. To determine the effectiveness of seated thoracic manipulation versus targeted supine thoracic manipulation on cervical spine pain and flexion range of motion (ROM). There is evidence that thoracic spine manipulation is an effective treatment for patients with cervical spine pain. This evidence includes a variety of techniques to manipulate the thoracic spine. Although each of them is effective, no research has compared techniques to determine which produces the best outcomes. A total of 39 patients with cervical spine pain were randomly assigned to either a seated thoracic manipulation or targeted supine thoracic manipulation group. Pain and flexion ROM measures were taken before and after the intervention. Pain reduction (post-treatment-pre-treatment) was significantly greater in those patients receiving the targeted supine thoracic manipulation compared to the seated thoracic manipulation (Pmanipulation group. The results of this study indicate that a targeted supine thoracic manipulation may be more effective in reducing cervical spine pain and improving cervical flexion ROM than a seated thoracic manipulation. Future studies should include a variety of patients and physical therapists (PTs) to validate our findings.

The rebirth of the cervical cap.

Cappiello, J D; Grainger-Harrison, M

1981-01-01

In an effort to dispel myths surrounding the cervical cap, the historical and political factors affecting the cap's use in the U.S. are described. Clinical aspects of cap fitting are also included. The cervical cap has found only limited acceptance in the U.S. Skepticisms on the part of physicians may be the result of 2 factors: confusion of the cervical cap with intracervical devices used for artificial insemination and confusion with stem pessaries; and the lack of clinical research and statistical evaluation of efficacy rates. The latter factor prompted Tietze et al. to conduct the only U.S. statistical study of the cap in 1953. Of the 143 women studied, the pregnancy rate was 7.6/100 years of use. Of the 28 unplanned pregnancies, 6 were related to faulty technique or omission of a spermicide and 10 were instances of admittedly irregular use. When these failures are omitted, the theoretical effectiveness rate is about 98%. Some practitioners are concerned about an increased incidence of cervical erosion with cap use. Possibly currently conducted studies will show that cap and spermicide users have a lower incidence of cervical erosion than women using no contraceptive method. Study findings suggest that the cervical cap may afford protection without any spermicidal supplement, but the use of spermicides continues to be recommended to clients. Advantages of the cervical cap include the following: it can be left in place longer than a diaphragm without additional applications of spermicide in the vagina; and the insertion of the cap is unrelated to the time of intercourse. Despite research on toleration of the cap for 3 weeks at a time, it is recommended that the cap be worn for only a few days at a time. At this time there are no manufacturers of cervical caps for contraceptive use in the U.S. The cap is now being imported from England and it costs $6.00. A factor that has made the cap unpopular with many physicians is the lengthy time required for fitting. An

Cervical spine injuries in Rugby Union are a concerning issue at all levels of the game. The primary aim of this retrospective analysis conducted in a professional Rugby Union squad was to determine whether a 26-week isometric neck strengthening intervention program (13-week strengthening phase and 13-week maintenance phase) was effective in reducing the number and severity of cervical spine injuries. The secondary aim was to determine whether at week five, where the program had been the similar for all players, there was increased isometric neck strength. All 27 players who were common to both the 2007-2008 and 2008-2009 seasons were included in this analysis and data was extracted from a Sports Medicine/Sports Science database which included the squad's injury records. Primary outcome variables included; the number of cervical spine injuries and the severity of these injuries as determined by the total number of days lost from training and competition. Secondary outcome variables included isometric neck strength in flexion, extension and left and right lateral flexion. Using non-parametric statistical methods, no significant differences were evident for the total number of cervical spine injuries (n = 8 in 2007-2008, n = 6 in 2008-2009) or time loss due to these injuries (100 days in 2007-2008, 40 days in 2008-2009). However, a significant (p = 0.03) reduction in the number of match injuries was evident from 2007-2008 (n = 11) to 2008-09 (n = 2). Non-significant increases in isometric neck strength were found in all directions examined. A significant reduction in the number of match injuries was evident in this study. However, no other significant changes to primary outcome variables were achieved. Further, no significant increases in isometric neck strength were found in this well-trained group of professional athletes. Key Points While many authors have proposed that neck strengthening could be an effective strategy in preventing cervical spine injuries in

Cyclin-dependent kinase inhibitor 2A (CDKN2A is a well-documented tumor suppressor gene and is commonly methylated in cervical cancer. However, the relationship between methylated CDKN2A and carcinogenesis in cervical cancer is inconsistent, and the diagnostic accuracy of methylated CDKN2A is underinvestigated. In this study, we attempted to quantify the association between CDKN2A methylation and the carcinogenesis of cervical cancer, and its diagnostic power.Methods: We systematically reviewed four electronic databases and identified 26 studies involving 1,490 cervical cancers, 1,291 CINs, and 964 controls. A pooled odds ratio (OR with corresponding 95% confidence intervals (95% CI was calculated to evaluate the association between methylated CDKN2A and the carcinogenesis of cervical cancer. Specificity, sensitivity, the area under the receiver operating characteristic curve, and the diagnostic odds ratio were computed to assess the effect of methylated CDKN2A in the diagnosis of cervical cancer.Results: Our results indicated an upward trend in the methylation frequency of CDKN2A in the carcinogenesis of cervical cancer (cancer vs control: OR =23.67, 95% CI =15.54–36.06; cancer vs CIN: OR =2.53, 95% CI =1.79–3.5; CIN vs control: OR =9.68, 95% CI =5.82–16.02.

Cervical mucus properties stratify risk for preterm birth.

Full Text Available Ascending infection from the colonized vagina to the normally sterile intrauterine cavity is a well-documented cause of preterm birth. The primary physical barrier to microbial ascension is the cervical canal, which is filled with a dense and protective mucus plug. Despite its central role in separating the vaginal from the intrauterine tract, the barrier properties of cervical mucus have not been studied in preterm birth.To study the protective function of the cervical mucus in preterm birth we performed a pilot case-control study to measure the viscoelasticity and permeability properties of mucus obtained from pregnant women at high-risk and low-risk for preterm birth. Using extensional and shear rheology we found that cervical mucus from women at high-risk for preterm birth was more extensible and forms significantly weaker gels compared to cervical mucus from women at low-risk of preterm birth. Moreover, permeability measurements using fluorescent microbeads show that high-risk mucus was more permeable compared with low-risk mucus.Our findings suggest that critical biophysical barrier properties of cervical mucus in women at high-risk for preterm birth are compromised compared to women with healthy pregnancy. We hypothesize that impaired barrier properties of cervical mucus could contribute to increased rates of intrauterine infection seen in women with preterm birth. We furthermore suggest that a robust association of spinnbarkeit and preterm birth could be an effectively exploited biomarker for preterm birth prediction.

Full Text Available Objective: To study the effect of Twist, Snail and YB-1 gene expression in cervical cancer tissue on cell invasion and epithelial-mesenchymal transition. Methods: Cervical cancer tissue samples and tissue samples adjacent to carcinoma were collected from 138 patients with radical operation for cervical cancer, fluorescence quantitative PCR method was used to detect the mRNA expression of Twist, Snail and YB-1 genes, cell invasion-related genes and epithelial-mesenchymal transition marker genes, the Pearson test was used to analyze the correlation of Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue with cell invasion and epithelial-mesenchymal transition. Results: Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue were higher than those in tissue adjacent to carcinoma, the invasion genes STAT3, YAP1, TUG1, FoxM1 and Rab11 mRNA expression were higher than those in tissue adjacent to carcinoma, and the epithelial-mesenchymal transition markers E-cadherin and β-catenin gene mRNA expression were lower than those in tissue adjacent to carcinoma while vimentin gene mRNA expression was higher than that in tissue adjacent to carcinoma. Pearson test showed that Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue were directly correlated with cell invasion and epithelial-mesenchymal transition. Conclusion: Twist, Snail and YB-1 genes are highly expressed in cervical cancer tissue, and their abnormal expression directly leads to the increased tumor cell invasion activity and the aggravated epithelial-mesenchymal transition.

Full Text Available Tricyclic antidepressants (TCAs, such as amitriptyline, have many side effects. But extrapyramidal tract symptom is an uncommon side effect of these drugs. Here, we report a case of a 28-year-old male who is suffering from amitriptyline induced cervical dystonia. Though rare, this side effect is an uncomfortable condition and may influence drug compliance. So clinicians should be aware of this side effect while treating a patient with amitriptyline.

Cervical cancer remains a global health related issue among females of Sub-Saharan Africa, with over half a million new cases reported each year. Different therapeutic regimens have been suggested in various regions of Africa, however, over a quarter of a million women die of cervical cancer, annually. This makes it the most lethal cancer amongst black women and calls for urgent therapeutic strategies. In this study we compare the anti-proliferative effects of crude extract of Cannabis sativa and its main compound cannabidiol on different cervical cancer cell lines. To achieve our aim, phytochemical screening, MTT assay, cell growth analysis, flow cytometry, morphology analysis, Western blot, caspase 3/7 assay, and ATP measurement assay were conducted. Results obtained indicate that both cannabidiol and Cannabis sativa extracts were able to halt cell proliferation in all cell lines at varying concentrations. They further revealed that apoptosis was induced by cannabidiol as shown by increased subG0/G1 and apoptosis through annexin V. Apoptosis was confirmed by overexpression of p53, caspase 3 and bax. Apoptosis induction was further confirmed by morphological changes, an increase in Caspase 3/7 and a decrease in the ATP levels. In conclusion, these data suggest that cannabidiol rather than Cannabis sativa crude extracts prevent cell growth and induce cell death in cervical cancer cell lines.

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.

To investigate the frequency and effective treatment of ulcers and sinuses in cases of tuberculous cervical lymphadenitis (TCL). Observational cross-sectional study. Department of ENT, Head and Neck Surgery of Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal, during the period of two years from March, 2000 to February, 2002. A hundred cases of histopathologically confirmed cases of tuberculous cervical lymphadenitis of more than six weeks of duration were included in the study. Overall frequency of the complication as well as the efficacy of treatment regime was considered. Out of 100 patients, 8 (8%) were found to develop ulcers and/or sinuses during the process of development of TCL which were effectively treated (100% cure rate). Mode of treatment was surgical excision of ulcers/sinuses along with affected underlying lymph nodes, followed by short course of anti-tubercular chemotherapy. Not a single case recurred during their follow-up period. In this series there was a low frequency of formation of ulcers/sinuses during the process of development of TCL. Surgical excision of ulcers/sinuses along with affected underlying lymph nodes, followed by short course of anti-tubercular chemotherapy is the effective methods of their treatment.

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

Full Text Available Spinal injury following direct loading of the head and neck is a rare sequel of bicycle crashes. Fatal head injuries following bicycle crashes have been described in great detail and safety measures such as bicycle helmets have been developed accordingly. Less frequently, however, potentially severe cervical spine injuries have been described. We present the case of a middle-aged female who sustained an ultimately fatal cervical spine injury following a collision with a car whilst biking wearing a helmet. We discuss the literature regarding the protective effects of bicycle helmets, the relevance to cervical spine injury and legislation on mandatory use of helmets for injury prevention.

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

Objective: To explore the value of MR imaging-guided percutaneous cervical discectomy and discolysis with oxygen-ozone mixture for treatment of cervical disc herniation. Methods: Eight herniated cervical discs in 7 patients were diagnosed by MRI, inclluding 5 discs of lateral protruding type, 2 discs of paramedian protruding type and one disc of central protruding type. All patients underwent MR imaging-guided percutaneous cervical discectomy and discolysis with oxygen-ozone mixture. The procedures were guided by a set of 0.23 T open MR system mounted with iPath 200 optical tracking system. The herniated portion of the disc was punctured with a 14 G MR-comparible needle in the healthy side via anterolateral oblique route. The interventional steps were as follows: firstly, cut herniated part with percutaneous discectomy probe and inject 2ml oxygen-ozone mixture of 60 μg/ml; secondly, retreat the needle to the disc center, resect nucleus pulposus, and inject 2 ml oxygen-ozone mixture of 60 μg/ml; secondly, retreat the needle to the disc center, resect nucleus pulposus, and inject 2 ml oxygen-ozone mixture of 60 μg/ml. All patients were followed up for 6 months, with 4 patients by telephone and 3 patients in outpatient clinic. The effect of treatment was evaluated according to Williams postoperative assessment standard. Results: All procedures were performed successfully. The clinical outcome was evaluated as excellent in 5 cases, good in 1 cases and fair in 1 case. The total ratio of excellent and good was 85.7%. No serious complication occurred expect 1 case with intraoperative paroxysmal pain. Conclusion: MR imaging-guided percutaneous cervical discectomy and discolysis with oxygen-ozone mixture was a safe, effective and minimally invasive method for the treatment of cervical disc herniation.

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.

Lessons learned from successful Papanicolaou cytology cervical cancer prevention in the Socialist Republic of Vietnam.

2012-04-01

In 1996, we documented that the burden of cervical cancer in Vietnam was associated with troop movements during the Vietnam War. Subsequently, establishment of Papanicolaou screening in southern Vietnam was associated with reductions in cervical cancer incidence from 29.2/100,000 in 1998 to 16/100,000 in 2003. This is one of the first English-language reports of a real-world cervical cancer prevention effort associated with a decisive impact on health outcomes in a contemporary developing country. if our ideological commitment is to improve health outcomes as rapidly as possible among as many people as possible, then Papanicolaou screening (with or without HPV or visual screening) must be implemented without further delay in any setting where cervical screening is appropriate but unavailable; consideration must be given to HPV vaccination after, rather than before, full coverage of target demographic groups by screening services has been achieved and/or the possibility has been excluded that HPV vaccination may be ineffective for cancer prevention. Competing ideological commitments engender imprudent yet commercially useful alternative strategies prone to decelerate global reductions in mortality by suppressing the more-rapid uptake of less-expensive open-source technology in favor of the less-rapid uptake of more-expensive proprietary technologies with uncertain real-world advantages and unfavorable real-world operational limitations. Global cervical cancer prevention efforts will become more effective if global health leaders, including the Bill & Melinda Gates Foundation, embrace an ideological commitment to improving health outcomes as rapidly as possible among as many people as possible and assimilate the policy implications of that commitment.

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.

Appropriate warming of the periocular or posterior cervical skin has been reported to induce autonomic or mental relaxation in humans. To clarify the effects of cutaneous warming on human sleep, eight male subjects with mild sleep difficulties were asked to try three experimental conditions at home, each lasting for 5 days, in a cross-over manner: warming of the periocular skin with a warming device for 10 min before habitual bedtime, warming of the posterior cervical skin with a warming device for 30 min before habitual bedtime, and no treatment as a control. The warming device had a heat- and steam-generating sheet that allowed warming of the skin to 40 °C through a chemical reaction with iron. Electroencephalograms (EEGs) were recorded during nocturnal sleep using an ambulatory EEG device and subjected to spectral analysis. All the participants reported their sleep status using a visual analog scale. We found that warming of the periocular or posterior cervical skin significantly improved subjective sleep status relative to the control. The EEG delta power density in the first 90 min of the sleep episode was significantly increased under both warming of the periocular or posterior cervical skin relative to the control. These results suggest that warming of appropriate skin regions may have favorable effects on subjective and objective sleep quality.

Cervical cancer is currently the leading cause of cancer mortality among women in South Vietnam and the second leading cause of cancer mortality in North Vietnam. Human papillomavirus (HPV) vaccination has the potential to substantially decrease this burden. The World Health Organization (WHO) recommends that a cost-effectiveness analysis of HPV vaccination is conducted before nationwide introduction. The Papillomavirus Rapid Interface for Modeling and Economics (PRIME) model was used to evaluate the cost-effectiveness of HPV vaccine introduction. A costing study based on expert panel discussions, interviews and hospital case note reviews was conducted to explore the cost of cervical cancer care. The cost of cervical cancer treatment ranged from US$368 - 11400 depending on the type of hospital and treatment involved. Under Gavi-negotiated prices of US$4.55, HPV vaccination is likely to be very cost-effective with an incremental cost per disability-adjusted life year (DALY) averted in the range US$780 - 1120. However, under list prices for Cervarix and Gardasil in Vietnam, the incremental cost per DALY averted for HPV vaccination can exceed US$8000. HPV vaccine introduction appears to be economically attractive only if Vietnam is able to procure the vaccine at Gavi prices. This highlights the importance of initiating a nationwide vaccination programme while such prices are still available.

The presence of endogenous acids from bacteria acting on a suitable substrate combined with sources of exogenous biocorrosives such as exogenous acids and proteolytic enzymes in areas of stress concentration are hypothesized to lead to the development and progression of cervical and root caries (RC). Quantifying the effects of each of the mechanisms (stress and biocorrosion) is a daunting task to investigate since so many factors are involved at various times in the etiology of noncarious cervical lesions (NCCLs), cervical caries (CC), and RC. Frictional action of the tongue has a cleansing effect and lingual serous saliva, which has a high flow rate buffering capacity from bicarbonates seem to account for the paucity of lingual NCCLs, cervical, and RC in these areas of teeth. Future studies are indicated to determine the effects of stress and biocorrosion and their factors in the etiology of CC and RC. This manuscript presents hypothetical and literary information that the combined effects of stress concentration and biocorrosion contribute to the formation as well as progression of cervical and root caries. © 2018 Wiley Periodicals, Inc.

Objective: To investigate cytotoxic and radiosensitizing effect of Artemisinin on cervical carcinoma cell line HeLa. Methods: In order to measure the optimized effective time, cytotoxic effect of Artemisinin on HeLa cell line was investigated with MTT assay. The radiosensitization effect of different doses and different treatment duration of Artemisinin on HeLa cell line were evaluated by MTT test, the SER is 1.17 and radiosensitizing effect was measured with multi-target single hit model through SER of HeLa cell. Cell cycles in different groups were calculated by flow cytometry. Results: The 50% inhibition concentration of Artemisinin interacted with HeLa cells for 24 h is 600.19 nmol/ml, and for 48 h is 160.71 nmol/ml. The HeLa cells'surival ratio is 93.51%, 91.87%, and 87.28% after adding Atemisinin of 110.69 nmol/ml and 1 Gy radiation exposure. There are three groups: the chemotherapy only group, the radiotherapy only group and the combination group. The result of the cell cycles showed that cells in G 2 /M period decreased in the combination group. Conclusion: Artemisinin has radiosensitization effect on cervical carcinoma HeLa cells, whichshows dose and time dependent. Artemisinin can inhibit the G 2 /M block by ionizing radiation. (authors)

Hart, William; Albarracín, Dolores

2009-12-01

This research examined the hypothesis that situational achievement cues can elicit achievement or fun goals depending on chronic differences in achievement motivation. In 4 studies, chronic differences in achievement motivation were measured, and achievement-denoting words were used to influence behavior. The effects of these variables were assessed on self-report inventories, task performance, task resumption following an interruption, and the pursuit of means relevant to achieving or having fun. Findings indicated that achievement priming (vs. control priming) activated a goal to achieve and inhibited a goal to have fun in individuals with chronically high-achievement motivation but activated a goal to have fun and inhibited a goal to achieve in individuals with chronically low-achievement motivation.

Objective: To discuss the clinical therapeutic effect and side reaction of superselective uterine arterial chemoembolization therapy for the treatment of cervical cancer. Methods: Bilateral uterine arterial chemoembolization was performed in 33 patients with pathologically-proved cervical cancer. The infusion drugs included DDP or L-OHP, EADM, MMC and 5-Fu. The Gelfoam particle was employed as embolic agent. The therapeutic effect evaluated by observing the improvement of clinical symptoms and the volume reduction of the tumor. Results: Of the total 33 patients with pathologically-confirmed cervical cancer, squamous cell carcinoma was seen in 29 and adenocarcinoma in 4. Based on FIGO classification (established by Federation International of Gynecology and Obstetrics), 6, 23 and 4 patients were classified in stage Ⅰ, Ⅱ and Ⅲ respectively. The angiography conducted during the procedure showed that the uterine arteries were markedly dilated, and spiral tumor-feeding arteries as well as tumor stain were also observed. Technical success together with perfect chemoembolization was achieved for 57 uterine arteries in 33 patients. Among the 33 patients, the interventional treatment was carried out three times in 2, two times in 2 and single time in 29. One week after the initial interventional procedure the remission rate of the clinical symptoms was 96% for squamous cell carcinoma and 100% for adenocarcinoma. One month after the treatment, the mean tumor volume was decreased by 30%, the tumor volume reduction for squamous cell carcinoma was 27.6% and was 50.0% for adenocarcinoma. Surgical resection after interventional therapy was carried out in 21 cases and additional radiotherapy after surgery or interventional procedure was adopted in 11 cases. The main adverse reactions after interventional procedure included fever, leucocytopenia, nausea, vomiting, abdominal pain, etc. Conclusion: Superselective uterine arterial chemoembolization is one of effective

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.

Multicenter retrospective case series. To determine the rate of thoracic duct injury during cervical spine operations. A retrospective case series study was conducted among 21 high-volume surgical centers to identify instances of thoracic duct injury during anterior cervical spine surgery. Staff at each center abstracted data for each identified case into case report forms. All case report forms were collected by the AOSpine North America Clinical Research Network Methodological Core for data processing, cleaning, and analysis. Of a total of 9591 patients reviewed that underwent cervical spine surgery, 2 (0.02%) incurred iatrogenic injury to the thoracic duct. Both patients underwent a left-sided anterior cervical discectomy and fusion. The interruption of the thoracic duct was addressed intraoperatively in one patient with no residual postoperative effects. The second individual developed a chylous fluid collection approximately 2 months after the operation that required drainage via needle aspiration. Damage to the thoracic duct during cervical spine surgery is a relatively rare occurrence. Rapid identification of the disruption of this lymphatic vessel is critical to minimize deleterious effects of this complication.

2012-01-01

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

Optimising population-based cervical screening policies is becoming more complex due to the expanding range of screening technologies available and the interplay with vaccine-induced changes in epidemiology. Mathematical models are increasingly being applied to assess the impact of cervical cancer screening strategies. We systematically reviewed MEDLINE®, Embase, Web of Science®, EconLit, Health Economic Evaluation Database, and The Cochrane Library databases in order to identify the mathematical models of human papillomavirus (HPV) infection and cervical cancer progression used to assess the effectiveness and/or cost-effectiveness of cervical cancer screening strategies. Key model features and conclusions relevant to decision-making were extracted. We found 153 articles meeting our eligibility criteria published up to May 2013. Most studies (72/153) evaluated the introduction of a new screening technology, with particular focus on the comparison of HPV DNA testing and cytology (n = 58). Twenty-eight in forty of these analyses supported HPV DNA primary screening implementation. A few studies analysed more recent technologies - rapid HPV DNA testing (n = 3), HPV DNA self-sampling (n = 4), and genotyping (n = 1) - and were also supportive of their introduction. However, no study was found on emerging molecular markers and their potential utility in future screening programmes. Most evaluations (113/153) were based on models simulating aggregate groups of women at risk of cervical cancer over time without accounting for HPV infection transmission. Calibration to country-specific outcome data is becoming more common, but has not yet become standard practice. Models of cervical screening are increasingly used, and allow extrapolation of trial data to project the population-level health and economic impact of different screening policy. However, post-vaccination analyses have rarely incorporated transmission dynamics. Model calibration to country

Preterm birth (PTB) presents a serious medical heath concern in both economically developed and developing nations, with incidence rate from 15%-11% respectively. Changes in cervical collagen bundle orientation and distribution may prove to be a predictor of PTB. Polarization imaging is an effective means to measure optical anisotropy in birefringent biological tissue such as those rich in collagen. Non-invasive, full-field Mueller Matrix polarimetry (MMP) imaging methodologies, optical coherence tomography (OCT), and second harmonic generation (SHG) microscopy were used to assess cervical collagen content and structure in non-pregnant cervices. In vivo studies using a Mueller Matrix colposcope are underway. Further studies of cervical collagen orientation throughout pregnancy are needed to understand if Mueller matrix polarimetry can effectively identify at-risk conditions for PTB.

To undertake a cost-effectiveness analysis that compares positron emission tomography - computed tomography (PET-CT) imaging plus standard practice with standard practice alone in the diagnosis of recurrent or persistent cervical cancer during routine surveillance and follow-up of women who have previously been diagnosed and treated. Model-based economic evaluation using data from a systematic review, supplemented with data from other sources, and taking a UK National Health Service (NHS) perspective. Secondary Care in England. Women at least 3 months after the completion of treatment, with either recurrent or persistent cervical cancer. A state transition (Markov) model was developed using TreeAge Pro 2011. The structure of the model was informed by the reviews of the trials and clinical input. In the model, two diagnostic strategies were examined. A one-way sensitivity analysis, probabilistic sensitivity analysis, and a value of information analysis were also carried out. Cost-effectiveness based on incremental cost per quality-adjusted life year (QALY). Adding PET-CT to the current treatment strategy of clinical examination and scanning [magnetic resonance imaging (MRI) and/or CT scan] during the routine surveillance and follow-up of women with recurrent or persistent cervical cancer is significantly more costly, with only a minimal increase in effectiveness. The incremental cost-effectiveness ratio (ICER) for the strategy of PET-CT as an adjunct to the standard treatment strategy that included clinical examination, MRI, and/or CT scan, compared with the usual treatment alone, was over £1 million per QALY. The results of the current analysis suggest that use of PET-CT in the diagnosis of recurrent or persistent cervical cancer is not cost-effective. Current guidelines recommending imaging using PET-CT as a diagnostic or surveillance tool need to be reconsidered in light of these results. This study did not specifically investigate the use of PET-CT in women

O'Ryan, Miguel; Valenzuela, María Teresa

Molecular, clinical and epidemiological studies have established beyond doubt that human papiloma viruses (HPV) cause cervical cancer. The virus is also associated with genital warts and other less common cancers in oropharynx, vulva, vagina and penis. Worldwide, VPH genotypes 16 and 18 are the most common high risk genotypes, detected in near 70% of women with cervical cancer. The discovery of a cause-effect relationship between several carcinogenic microorganisms and cancer open avenues for new diagnostic, treatment and prevention strategies. In this issue of Revista Médica de Chile, two papers on HPV are presented. Guzman and colleagues demonstrate that HPV can be detected in 66% to 77% of healthy male adolescents bypolymerase chain reaction and that positivity depends on the site of the penis that is sampled. These results support the role of male to female transmission of high risk HPVs in Chile and should lead to even more active educational campaigns. The second paper provides recommendations for HPV vaccine use in Chile, generated by the Immunization Advisory Committee of the Chilean Infectious Disease Society. To issue these recommendations, the Committee analyzes the epidemiological information available on HPV infection and cervical cancer in Chile, vaccine safety and effectiveness data, and describes cost-effectiveness studies. Taking into account that universal vaccination is controversial, the Committee favors vaccine use in Chile and it's incorporation into a national program. However, there is an indication that the country requires the implementation of an integrated surveillance approach including cross matching of data obtained from HPV genotype surveillance, monitoring of vaccination coverage, and surveillance of cervical cancer. The final decision of universal vaccine use in Chile should be based on a through analysis of information.ev Mid Chile

Caudal epidural anesthesia during intracavitary brachytherapy for cervical cancer

2015-01-01

It has been suggested that pain control during intracavitary brachytherapy for cervical cancer is insufficient in most hospitals in Japan. Our hospital began using caudal epidural anesthesia during high-dose-rate (HDR) intracavitary brachytherapy in 2011. The purpose of the present study was to retrospectively investigate the effects of caudal epidural anesthesia during HDR intracavitary brachytherapy for cervical cancer patients. Caudal epidural anesthesia for 34 cervical cancer patients was performed during HDR intracavitary brachytherapy between October 2011 and August 2013. We used the patients' self-reported Numeric Rating Scale (NRS) score at the first session of HDR intracavitary brachytherapy as a subjective evaluation of pain. We compared NRS scores of the patients with anesthesia with those of 30 patients who underwent HDR intracavitary brachytherapy without sacral epidural anesthesia at our hospital between May 2010 and August 2011. Caudal epidural anesthesia succeeded in 33 patients (97%), and the NRS score was recorded in 30 patients. The mean NRS score of the anesthesia group was 5.17 ± 2.97, significantly lower than that of the control group's 6.80 ± 2.59 (P = 0.035). The caudal epidural block resulted in no side-effects. Caudal epidural anesthesia is an effective and safe anesthesia option during HDR intracavitary brachytherapy for cervical cancer. (author)

Cervical screening in HPV-vaccinated populations.

Science.gov (United States)

Canfell, K

2018-06-01

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

Cervical 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.

To present the results from the clinical presentation, the imaging diagnostics, surgery and postoperative status of 17 patients with cervical spine metastases, to analyse all data and make the respective conclusions and compare them with the available data in the literature. The study analysed data obtained by patients with metastatic cervical tumours treated in St George University Hospital over a period of seven years. All patients underwent diagnostic imaging tests which included, separately or in combination, cervical x-rays, computed tomography scan and magnetic-resonance imaging. Severity of neurological damage and its pre- and postoperative state was graded according to the Frankel Scale. For staging and operating performance we used the Tomita scale and Harrington classification. Seven patients had only one affected vertebra, 4 patients--two vertebrae, one patient--three vertebrae, 2 patients--four vertebrae, and in the other 3 patients more than one segment was affected. Surgery was performed in 12 patients. One level anterior corpectomy was performed in 6 patients, three patients had two-level surgery, and one patient--three-level corpectomy; in the remaining 2 cases we used posterior approach in surgery. Complete corpectomy was performed in 4 patients, subtotal corpectomy was used in 6 patients and partial--in 2 patients. Anterior stabilization system ADD plus (Ulrich GmbH & Co. KG, Ulm, Germany) was implanted in 2 patients; in 8 patients anterior titanium plate and bone graft were used, and in 1 patient--posterior cervical stabilization system. Because of the pronounced pain syndrome and frequent neurological lesions as a result of the cervical spine metastases use of surgery is justified. The main purpose is to maximize tumor resection, achieve optimal spinal cord and nerve root decompression and stabilize the affected segment.

Full Text Available Aspirin and other nonsteroidal anti-inflammatory drugs show efficacy in the prevention of cancers. It is known that they can inhibit cyclooxygenases, and some studies have shown that they can induce apoptosis. Our objective in this study was to investigate the mechanism by which aspirin exerts its apoptosis effects in human cervical cancer HeLa cells. The effect of aspirin on the gene expression was studied by differential mRNA display RT-PCR. Among the isolated genes, mu-type calpain gene was upregulated by aspirin treatment. To examine whether calpain mediates the antitumor effects, HeLa cells were stably transfected with the mammalian expression vector pCR3.1 containing mu-type calpain cDNA (pCRCAL/HeLa, and tumor formations were measured in nude mice. When tumor burden was measured by day 49, HeLa cells and pCR/HeLa cells (vector control produced tumors of 2126 mm3 and 1638 mm3, respectively, while pCRCAL/HeLa cells produced markedly smaller tumor of 434 mm3 in volume. The caspase-3 activity was markedly elevated in pCRCAL/HeLa cells. The increased activity levels of caspase-3 in pCRCAL/HeLa cells, in parallel with the decreased tumor formation, suggest a correlation between caspase-3 activity and calpain protein. Therefore, we conclude that aspirin-induced calpain mediates an antitumor effect via caspase-3 in cervical cancer cells.

The purpose of this study was to evaluate the efficacy of concurrent chemoradiation with intra-arterial docetaxel-nedaplatin infusion to metastatic cervical lymph nodes in oral cancers. Sixteen patients with advanced oral cancer accompanied by cervical lymph node metastasis were treated between 2003 and 2009 at Hirosaki University Hospital. A total of 66 Gy of external beam irradiation concurrent with 2 to 3 courses of intra-arterial chemotherapy infusion via the femoral artery with a combination of docetaxel (40 mg/m 2 ) and nedaplatin (80 mg/m 2 ) was conducted. Amongst the 16 patients, 6 received a total anticancer drug delivery to the primary tumor and 10 received a partial delivery to the nodal disease. The feeding artery to the nodal disease was the facial artery in 3 patients and the occipital artery in 3 patients. The remaining 4 patients received anticancer drug infusion to the external carotid artery with arterial redistribution technique where embolization was applied in order to achieve an antitumor effect due to a high local concentration. Treatment effect was evaluated by computed tomography (CT), magnetic resonance imaging and positron emission tomography-CT (PET-CT). Metastatic cervical lymph nodes disappeared in 15 out of the 16 patients (93.8%) post-treatment. Neck dissection was performed for the patient with residual nodal disease. One patient had neck recurrence at level V in ipsilateral neck. The three-year overall survival rate was 74.6% with a median follow-up duration of 27 months. Intra-arterial docetaxel-nedaplatin infusion concurrent with radiotherapy is an effective treatment not only for primary disease but also for metastatic cervical lymph nodes. (author)

Balance chiropractic therapy for cervical spondylotic radiculopathy: study protocol for a randomized controlled trial.

Yang, Feng; Li, Wen-Xiong; Liu, Zhu; Liu, Li

2016-10-22

Cervical spondylosis is a very common disorder and cervical spondylotic radiculopathy (CSR) is the most common form of spinal degenerative disease. Its clinical manifestations focus on pain and numbness of the neck and arm as well as restricted movement of the neck, which greatly affect the patient's life and work. The orthopedic of traditional Chinese medicine (TCM) theory holds that the basic pathologic change in spinal degenerative diseases is the imbalance between the dynamic system and the static system of the cervical spine. Based on this theory, some Chinese physicians have developed a balance chiropractic therapy (BCT) to treat CSR, which has been clinically examined for more than 50 years to effectively cure CSR. The purpose of this study is to evaluate the therapeutic effect and safety of BCT on CSR and to investigate the mechanism by which the efficacy is achieved. We propose a multicenter, parallel-group, randomized controlled trial to evaluate the efficacy and safety of BCT for CSR. Participants aged 18 to 65 years, who are in conformity with the diagnostic criteria of CSR and whose pain score on a Visual Analog Scale (VAS) is more than 4 points and less than 8 points, will be included and randomly allocated into two groups: a treatment group and a control group. Participants in the treatment group will be treated with BCT, while the control group will receive traction therapy (TT). The primary outcome is pain severity (measured with a VAS). Secondary outcomes will include cervical curvature (measured by the Borden Index), a composite of functional status (measured by the Neck Disability Index, NDI), patient health status (evaluated by the SF-36 health survey) and adverse events (AEs) as reported in the trial. If BCT can relieve neck pain without adverse effects, it may be a novel strategy for the treatment of CSR. Furthermore, the mechanism of BCT for CSR will be partially elucidated.

Many refugees in the United States emigrated from countries where the incidence of cervical cancer is high. Refugee women are unlikely to have been screened for cervical cancer prior to resettlement in the U.S. National organizations recommend cervical cancer screening for refugee women soon after resettlement. We sought to identify health and social service providers' perspectives on promoting cervical cancer screening in order to inform the development of effective programs to increase screening among recently resettled refugees. This study consisted of 21 in-depth key informant interviews with staff from voluntary refugee resettlement agencies, community based organizations, and healthcare clinics serving refugees in King County, Washington. Interview transcripts were analyzed to identify themes. We identified the following themes: (1) refugee women are unfamiliar with preventive care and cancer screening; (2) providers have concerns about the timing of cervical cancer education and screening; (3) linguistic and cultural barriers impact screening uptake; (4) provider factors and clinic systems facilitate promotion of screening; and (5) strategies for educating refugee women about screening. Our findings suggest that refugee women are in need of health education on cervical cancer screening during early resettlement. Frequent messaging about screening could help ensure that women receive screening within the early resettlement period. Health education videos may be effective for providing simple, low literacy messages in women's native languages. Appointments with female clinicians and interpreters, as well as clinic systems that remind clinicians to offer screening at each appointment could increase screening among refugee women.

Although cervical cancer can be prevented through screening and follow-up, Latinas' rate of Pap tests remains low due to knowledge gaps and cultural and attitudinal factors. This study used a single-group pre-/post-test design to evaluate the effectiveness of Mujer Sana, Familia Fuerte (Healthy Woman, Strong Family), an intervention intended to improve Latinas' cervical cancer prevention knowledge, attitudes, self-efficacy to obtain a Pap test, and intention to get tested. The intervention is delivered through a single session by promotores de salud, who use a culturally competent, linguistically appropriate toolkit. A total of 5,211 Latinas participated in the study. The evaluation indicated that participants had increases in knowledge, positive attitudes, self-efficacy, and intention to test. Latinas have a low rate of cervical cancer screening but a high rate of cervical cancer, and Mujer Sana, Familia Fuerte shows promise as a public health practice for use with this population.

Treatment results of neck dissection with the preservation of cervical nerves for hypopharyngeal cancer were analyzed retrospectively by comparing neck dissection with the preservation of cervical nerves and that with the resection of cervical nerves. Pharyngolaryngectomy or pharyngolaryngoesophagectomy with bilateral neck dissection was performed in 76 hypopharyngeal cancer cases between January 1992 and November 2001. Neck dissection with the resection of cervical nerves was performed on 42 sides of the neck in 21 cases (the cervical nerve-resected group). In 55 cases we attempted to employ neck dissection with the preservation of cervical nerves, but in 9 cases the cervical nerves were resected because of their nodal adhesion or involvement Neck dissection with the preservation of cervical nerves was performed on 92 sides of the neck in 46 cases (the cervical nerve-preserved group). There were significant differences between background factors of two groups about age, sex, induction chemotherapy, preservation of accessory nerve, and pN classification. The 5-year cumulative control rates of cervical lymph nodes were 81.3% for the cervical nerve-resected group and 79.7% for the cervical nerve-preserved group. There was no significant difference between the two groups. It was suggested that neck dissection with the preservation of cervical nerves for cases whose cervical nerves were able to be preserved from metastatic lymph nodes under induction chemotherapy and post-operative irradiation was as effective to control cervical lymph nodes as neck dissection with the resection of cervical nerves.

To introduce the outcomes of tracheal resection with primary end to end anastomosis for benign cervical tracheal stenosis, and to discuss the strategy for prevention of surgical complications. A retrospective analysis was performed in 12 patients diagnosed as benign cervical tracheal stenosis from October 2009 to June 2012. Laryngo-tracheal endoscopic examination and computed tomography (CT) were used to assess the degree of stenosis, the grade of inflammation and edema of the subglottis and trachea, and the extent of stenosis and the remaining linear amount of normal airway. The Meyer and Cotton grading system was used to categorise the clinical severity of the stenoses. All patients underwent tracheal resection with primary end to end anastomosis. The length of cervical tracheal stenosis ranged from 2.3 to 4.1 cm. Grade II stenosis was present in three patients, Grade III stenosis was present in seven patients and grade IV stenosis in two patients. Successful extubation was achieved in all 12 cases. After surgery, temporary hoarseness occurred in 1 patient (8.3%); unilateral pulmonary atelectasis with pleural effusion occurred in 1 patient (8.3%); subcutaneous emphysema with infection occurred in 1 patient (8.3%); mild dysphagia occurred in 3 patients (25.0%); a slight deepening of the tone of voice occurred in 5 patients (41.7%), granulation tissue growth near the suture occurred in 3 patients (25.0%), and suture dehiscence did not occur in any patient. The follow-up period ranged from 6 months to 38 months, no patient developed restenosis. It presents a high success rate and good functional result of tracheal resection with primary end-to-end anastomosis. Therefore, it is an effective and reliable approach for the management of benign cervical tracheal stenosis. To avoid complications, the preoperative assessment, patients selection and postoperative management should be emphasized.

The objective of this study was to compare the clinical outcomes of the cervical interlaminar epidural steroid injection (CIESI) for unilateral radiculopathy by the midline or paramedian approaches and to determine the prognostic factors of CIESI. We retrospectively analyzed 182 patients who underwent CIESI from January 2009 to December 2012. Inclusion criteria were no previous spinal steroid injection, presence of a cross-sectional image, and presence of follow-up records. Exclusion criteria were patients with bilateral cervical radiculopathy and/or dominant cervical axial pain, combined peripheral neuropathy, and previous cervical spine surgery. Short-term clinical outcomes were evaluated at the first follow-up after CIESI. We compared the clinical outcomes between the midline and paramedian approaches. Possible prognostic factors for the outcome, such as age, gender, duration of radiculopathy, and cause of radiculopathy were also analyzed. Cervical interlaminar epidural steroid injections were effective in 124 of 182 patients (68.1%) at the first follow-up. There was no significant difference in the clinical outcomes of CIESI, between midline (69.6%) and paramedian (63.7%) approaches (p = 0.723). Cause of radiculopathy was the only significant factor affecting the efficacy of CIESI. Patients with disc herniation had significantly better results than patients with neural foraminal stenosis (82.9% vs. 56.0%) (p < 0.001). There is no significant difference in treatment efficacy between the midline and paramedian approaches in CIESI, for unilateral radiculopathy. The cause of the radiculopathy is significantly associated with the treatment efficacy; patients with disc herniation experience better pain relief than those with neural foraminal stenosis.

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.

The HPV types that cause cervical cancer are sexually transmitted, but there is little evidence that infection can be avoided by behavioural changes, such as condom use. In contrast, prophylactic vaccines against HPV infection are likely to have high efficacy. In principle, the effectiveness of HPV vaccination as a strategy for cervical cancer control can be measured either by monitoring secular trends in cervical cancer incidence or by conducting randomized trials. The former approach is unl...

FZUImageReg: A toolbox for medical image registration and dose fusion in cervical cancer radiotherapy.

Directory of Open Access Journals (Sweden)

Qinquan Gao

Full Text Available The combination external-beam radiotherapy and high-dose-rate brachytherapy is a standard form of treatment for patients with locally advanced uterine cervical cancer. Personalized radiotherapy in cervical cancer requires efficient and accurate dose planning and assessment across these types of treatment. To achieve radiation dose assessment, accurate mapping of the dose distribution from HDR-BT onto EBRT is extremely important. However, few systems can achieve robust dose fusion and determine the accumulated dose distribution during the entire course of treatment. We have therefore developed a toolbox (FZUImageReg, which is a user-friendly dose fusion system based on hybrid image registration for radiation dose assessment in cervical cancer radiotherapy. The main part of the software consists of a collection of medical image registration algorithms and a modular design with a user-friendly interface, which allows users to quickly configure, test, monitor, and compare different registration methods for a specific application. Owing to the large deformation, the direct application of conventional state-of-the-art image registration methods is not sufficient for the accurate alignment of EBRT and HDR-BT images. To solve this problem, a multi-phase non-rigid registration method using local landmark-based free-form deformation is proposed for locally large deformation between EBRT and HDR-BT images, followed by intensity-based free-form deformation. With the transformation, the software also provides a dose mapping function according to the deformation field. The total dose distribution during the entire course of treatment can then be presented. Experimental results clearly show that the proposed system can achieve accurate registration between EBRT and HDR-BT images and provide radiation dose warping and fusion results for dose assessment in cervical cancer radiotherapy in terms of high accuracy and efficiency.

Cervical spinal cord injuries in patients with cervical spondylosis.

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

1986-02-01

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

MicroRNA-373 functions as an oncogene and targets YOD1 gene in cervical cancer

2015-01-01

miR-373 was reported to be elevated in several tumors; however, the role of miR-373 in cervical cancer has not been investigated. In this study we aimed to investigate the role of miR-373 in tumorigenicity of cervical cancer cells in vivo and in vitro. The expression of miR-373 was investigated using real-time reverse transcription-polymerase chain reaction assay in 45 cervical specimens and cervical cancer cell lines. The role of miR-373 in tumorigenicity of cervical cancer cells was assessed by cell proliferation, colony formation in vitro as well as tumor growth assays in vivo with the overexpression of miR-373 or gene silencing. The functional target gene of miR-373 in cervical cancer cells was identified using integrated bioinformatics analysis, gene expression arrays, and luciferase assay. We founded that the expression of miR-373 is upregulated in human cervical cancer tissues and cervical carcinoma cell lines when compared to the corresponding noncancerous tissues. Ectopic overexpression of miR-373 in human cervical cancer cells promoted cell growth in vitro and tumorigenicity in vivo, whereas silencing the expression of miR-373 decreased the rate of cell growth. YOD1 was identified as a direct and functional target of miR-373 in cervical cancer cells. Expression levels of miR-373 were inversely correlated with YOD1 levels in human cervical cancer tissues. RNAi-mediated knockdown of YOD1 phenocopied the proliferation-promoting effect of miR-373. Moreover, overexpression of YOD1 abrogated miR-373-induced proliferation of cervical cancer cells. These results demonstrate that miR-373 increases proliferation by directly targeting YOD1, a new potential therapeutic target in cervical cancer. - Highlights: • The expression of miR-373 is upregulated in human cervical cancer tissues. • miR-373 effects as oncogenic miRNA in cervical cancer in vitro and in vivo. • miR-373 increases proliferation of cervical cancer cells by directly targeting YOD1

Although the cervical plexus block generally provides adequate analgesia for carotid endarterectomy, pain caused by metal retractors on the inferior surface of the mandible is not prevented by the cervical block. Different pain relief methods can be performed for patients who experience discomfort in these areas. In this study, the authors evaluated the effect of mandibular block in addition to cervical plexus block on pain scores in carotid endarterectomy. A prospective, randomized, controlled trial. Training and research hospital. Patients who underwent a carotid endarterectomy. Patients scheduled for carotid endarterectomy under cervical plexus block were randomized into 2 groups: group 1 (those who did not receive a mandibular block) and group 2 (those who received a mandibular block). The main purpose of the study was to evaluate the mandibular block in addition to cervical plexus block in terms of intraoperative pain scores. Intraoperative visual analog scale scores were significantly higher in group 1 (p = 0.001). The amounts of supplemental 1% lidocaine and intraoperative intravenous analgesic used were significantly higher in group 1 (p = 0.001 and p = 0.035, respectively). Patient satisfaction scores were significantly lower in group 1 (p = 0.044). The amount of postoperative analgesic used, time to first analgesic requirement, postoperative visual analog scale scores, and surgeon satisfaction scores were similar in both groups. There was no significant difference between the groups with respect to complications. No major neurologic deficits or perioperative mortality were observed. Mandibular block in addition to cervical plexus block provides better intraoperative pain control and greater patient satisfaction than cervical plexus block alone. Copyright © 2017 Elsevier Inc.

To assess the effect of implementation of a newly developed e-learning module on the quality of cervical-length measurements. With the introduction of cervical-length (CL) measurement in a research setting, a CL measurement e-learning module (CLEM) was developed with the purpose to enhance the knowledge and skills of experienced ultrasonographers. CLEM was designed specifically for ultrasonographers who perform ultrasound in a general obstetrical practice but who do not regularly perform CL measurements. CLEM consists of five theoretical questions and three caliper-placement tests to learn the CL measurement technique. The quality of the CL measurements of CLEM participants was compared with images of non-participants using a CL measurement image score (CIS), defined as the sum of six items which assess the quality of the image. Each CLEM participant submitted five CL images and the images of non-CLEM participants were selected randomly from an ultrasound database. The CIS of the CLEM participants (n = 61) were significantly higher than those of non-CLEM participants (n = 23) (164.9 vs 155.6, respectively; P = 0.03). Visualization of the internal os and positioning of the calipers on the internal and external ora were found to have significantly higher CIS among the CLEM participants than among the non-CLEM participants (P = 0.001 and P < 0.001, respectively). Introducing CLEM may improve the quality of CL measurements obtained by trained and untrained sonographers. Copyright © 2014 ISUOG. Published by John Wiley & Sons Ltd.

This study aimed to assess the effects of body mass index (BMI) on survival in cervical cancer patients who had undergone surgery and radiotherapy (RT). We retrospectively reviewed the medical records of 70 cervical cancer patients who underwent surgery and RT from 2007 to 2012. Among them, 40 patients (57.1%) had pelvic lymph node metastases at the time of diagnosis. Sixty-seven patients (95.7%) had received chemotherapy. All patients had undergone surgery and postoperative RT. Median BMI of patients was 22.8 kg/m2 (range, 17.7 to 35.9 kg/m2). The median duration of follow-up was 52.3 months (range, 16 to 107 months). Twenty-four patients (34.3%) showed recurrence. Local failure, regional lymph nodal failure, and distant failure occurred in 4 (5.7%), 6 (8.6%), and 17 (24.3%) patients, respectively. The 5-year actuarial pelvic control rate was 83.4%. The 5-year cancer-specific survival (CSS) and disease-free survival (DFS) rates were 85.1% and 65.0%, respectively. The presence of pelvic lymph node metastases (n = 30) and being overweight or obese (n = 34, BMI ≥ 23 kg/m2) were poor prognostic factors for CSS (p = 0.003 and p = 0.045, respectively). Of these, pelvic lymph node metastasis was an independent prognostic factor (p = 0.030) for CSS. Overweight or obese cervical cancer patients showed poorer survival outcomes than normal weight or underweight patients. Weight control seems to be important in cervical cancer patients to improve clinical outcomes

To investigate the relationship between neuron density of the superior cervical sympathetic ganglia and pupil diameter in subarachnoid hemorrhage. This study was conducted on 22 rabbits; 5 for the baseline control group, 5 for the SHAM group and 12 for the study group. Pupil diameters were measured via sunlight and ocular tomography on day 1 as the control values. Pupil diameters were re-measured after injecting 0.5 cc saline to the SHAM group, and autologous arterial blood into the cisterna magna of the study group. After 3 weeks, the brain, superior cervical sympathetic ganglia and ciliary ganglia were extracted with peripheral tissues bilaterally and examined histopathologically. Pupil diameters were compared with neuron densities of the sympathetic ganglia and ciliary ganglia which were examined using stereological methods. Baseline values were; normal pupil diameter 7.180±620 ?m and mean neuron density of the superior cervical sympathetic ganglia 6.321±510/mm3, degenerated neuron density of ciliary ganglia was 5±2/mm3 after histopathological examination in the control group. These values were measured as 6.850±578 ?m, 5.950±340/mm3 and 123±39/mm3 in the SHAM group and 9.910±840 ?m, 7.950±764/mm3 and 650±98/mm3 in the study group. A linear relationship was determined between neuron density of the superior cervical sympathetic ganglia and pupil diameters (p < 0.005). Degenerated ciliary ganglia neuron density had an inverse effect on pupil diameters in all groups (p < 0.0001). Highly degenerated neuron density of the ciliary ganglion is not responsible for pupil dilatation owing to parasympathetic pupilloconstrictor palsy, but high neuron density of the pupillodilatatory superior cervical sympathetic ganglia should be considered an important factor for pupil dilatation.

Cervical cancer is a very common malignancy amongst women worldwide. Pap smear is an effective and inexpensive screening test in asymptomatic women. The aim of this paper was to assess the prevalence of Pap smear screening for cervical cancer among Lebanese women and to determine associated sociodemographic and psychosocial characteristics. This national survey included 2255 women, selected by multi-stage random cluster sampling across Lebanon. A questionnaire about practices and perceptions related to cervical cancer screening was developed based on the "Health Belief Model". The weighted national prevalence of "ever-use" of the Pap smear for screening purposes was 35%. Most important determinants of screening behavior were: residence within Greater Beirut, higher socio-economic status and educational attainment, marriage status, presence of a health coverage, awareness of Pap smear usefulness, knowing someone who had already done it, and a balance between perceived benefits and perceived barriers to Pap smear screening. Regular information campaigns regarding the availability and effectiveness of the test should be devised, targeting in priority the sexually vulnerable women in Lebanon. Moreover, healthcare providers should be encouraged to discuss with their patients the opportunity of obtaining a Pap smear. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

In this study the effectiveness of computed tomographic discography (CTD) in diagnosing cervical soft disc hernia was evaluated. Twenty-five intervertebral discs of 15 cases with cervical soft disc hernia were examined with a discography and then a CT scan. Results of the CT scan were as follows: three discs were protruded, 12 discs were prolapsed, 6 discs were extruded, and 4 discs were sequestrated. The findings were helpful in determining the location of soft disc hernias between the median and posterolateral discs. They were also valuable in classifying types of hernias and surgical approaches.

This review provides a summary of the cost-effectiveness, clinical utility, performance, and interpretation of screening helical cervical spine CT for trauma patients. Recent evidence supports the use of helical CT as a cost-effective method for screening the cervical spine in high-risk trauma patients. Screening cervical spine CT can be performed at the time of head CT to lower the cost of the evaluation, and when all short- and long-term costs are considered, CT may actually save money when compared with traditional radiographic screening. In addition to having higher sensitivity and specificity for cervical spine injury, CT screening also allows more rapid radiological clearance of the cervical spine than radiography. Patients who are involved in high-energy trauma, who sustain head injury, or who have neurological deficits are candidates for CT screening. Screening with CT may enhance detection of other potentially important injuries of the cervical region. (orig.)

To investigate the role of radiotherapy (RT) in and to suggest radiotherapeutic strategies for patients presenting with disseminated cervical cancer. We retrospectively analyzed 50 patients diagnosed as the disseminated cervical cancer with distant lymph nodal or visceral organ metastasis between September 1980 and August 2012. Patients were divided into two subgroups according to visceral organ metastasis: 35 patients diagnosed with distant lymph node metastasis only (group A) and 15 patients with visceral organ metastasis (group B). All patients received external beam RT to the pelvis (median dose 45 Gy) and high-dose rate intracavitary RT (median dose 30 Gy). Thirty-nine patients (78%) received chemotherapy. Median follow-up time was 74 months. The 5-year pelvic control rate (PCR) was 85.8%, and the progression-free survival (PFS), and overall survival (OS) rates were 28.7%, and 36.2%, respectively. The major treatment failure was systemic progression (32 patients, 64%). The 5-year PCRs in groups A and B were 87.4% and 74.7%, respectively (p > 0.05). Meanwhile, PFS and OS rates for group A were significantly better than those for group B (35.3% vs. 13.3%, p = 0.010; and 46.3% vs. 13.3%, p = 0.009, respectively). Our data revealed considerable prognostic heterogeneity in disseminated cervical cancer. Even though a high PCR was achieved in patients treated with definitive RT, survival outcomes were dependent on progression of visceral organ metastasis. Therefore, personalized RT and chemotherapy treatment strategies according to the presence of visceral organ metastasis in disseminated cervical cancer patients may help improve clinical outcomes

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

Full Text Available The paradigm of preventing human papilloma virus (HPV infection through currently approved vaccines, namely, Gardasil, manufactured by Merck and Co., Inc. (Whitehouse Station, NJ and Cervarix, manufactured by GlaxoSmithKline (GSK, Philadelphia holds tremendous promise for the developing countries in decreasing the burden of HPV infection and its sequelae, such as cervical cancer, genital warts and anogenital cancers. Effective screening programs that have reduced the burden of this killer disease in the developed countries are still lacking in India, despite the high incidence of cervical cancer and the implementation of the National Cancer Control Programme since 1975. The recent breakthrough in the global war against cervical cancer will provide new insight for meeting the future challenge of the prevention of cervical cancer in India.

Patients with cervical compression myelopathy were studied to elucidate the mechanism underlying boomerang deformity, which results from the migration of the cervical spinal cord between split laminae after laminoplasty with median splitting of the spinous processes (boomerang sign). Thirty-nine cases, comprising 25 patients with cervical spondylotic myelopathy, 8 patients with ossification of the posterior longitudinal ligament, and 6 patients with cervical disc herniation with developmental canal stenosis, were examined. The clinical and radiological findings were retrospectively compared between patients with (B group, 8 cases) and without (C group, 31 cases) boomerang sign. Moderate increase of the grade of this deformity resulted in no clinical recovery, although there was no difference in clinical recovery between the two groups. Most boomerang signs developed at the C4/5 and/or C5/6 level, where maximal posterior movement of the spinal cord was achieved. Widths between lateral hinges and between split laminae in the B group were smaller than in the C group. Flatness of the spinal cord in the B group was more severe than in the C group. In conclusion, the boomerang sign was caused by posterior movement of the spinal cord, narrower enlargement of the spinal canal and flatness of the spinal cord.

Cervical and lumbar range of motion limitations are usually associated with musculoskeletal pain in the neck and lower back, and are a major health problem among nurses. Physical exercise has been evaluated as an effective intervention method for improving cervical and lumbar range of motion, and for preventing and reducing musculoskeletal pain. The purpose of this study was to investigate the effects of a home-exercise therapy programme on cervical and lumbar range of motion among intensive care unit nurses who had experienced mild to moderate musculoskeletal pain in the neck and or lower back during the previous six months. A quasi-experimental study was conducted among intensive care unit nurses at Tartu University Hospital (Estonia) between May and July 2011. Thirteen nurses who had suffered musculoskeletal pain episodes in the neck and or lower back during the previous six months underwent an 8-week home-exercise therapy programme. Eleven nurses without musculoskeletal pain formed a control group. Questions from the Nordic Musculoskeletal Questionnaire and the 11-point Visual Analogue Scale were used to select potential participants for the experimental group via an assessment of the prevalence and intensity of musculoskeletal pain. Cervical range of motion and lumbar range of motion in flexion, extension, lateral flexion and (cervical range of motion only) rotation were measured with a digital goniometer. A paired t-test was used to compare the measured parameters before and after the home-exercise therapy programme. A Student's t-test was used to analyse any differences between the experimental and control groups. After the home-exercise therapy, there was a significant increase (p cervical range of motion in flexion, extension, lateral flexion and rotation, and in lumbar range of motion in lateral flexion. Cervical range of motion in flexion was significantly higher (p cervical and lumbar range of motion among intensive care nurses. Further studies are

It has a good application prospect to predict effects of radiotherapy by examining radiosensitivity of patients with cervical cancers before their radiotherapy. Prediction of tumor cell radiosensitivity according to their level of gene expression and gene therapy to reverse radio-resistance prior to radiation on cervical cancers are heated researches on tumor therapy. The expression of some proliferation-related genes, apoptosis-related genes and hypoxia-related genes can inerease the radiosensitivity of cervical cancer. Microarray technology may have more direct applications to the study of biological pathway contributing to radiation resistance and may lead to development of alternative treatment modalities.

Full Text Available Introduction: Cervical cancer is the second prevalent cancer in developing countries and the sixth prevalent cancer in USA. Since conventional treatment methods are associated with detrimental side effects, searching for new drugs using natural ingredients is very important. Previous studies have shown that melittin (main component of honey bee venom has anticancer properties along with the effect on cell membrane and activation of apoptosis. In this study, inhibitory effects of melittin on the viability and proliferation of cervical cancer cell line (HeLa was investigated. Methods: Melittin was purified from honeybee venom using reversed-phase HPLC method. Then, biological activity of melittin was examined by hemolytic activity analysis on the red blood cells. In order to investigate whether melittin inhibits proliferation of HeLa cell, MTT assay was performed. HeLa cells were plated in a 96-well plate and treated with serially diluted concentrations of melittin for 12 and 24 hours. The viability of the cells was measured via MTT assay at 540nm. Results: Melittin showed a strong hemolytic activity (HD50=0.5 µg/ml which can be reduced by FBS(HD50=2 µg/ml. Results of MTT assay indicated that melittin shows cytotoxic effect on cervical cancer cells with IC50 = 1.2 ug/ml at 12h incubation period. Conclusion: In this study, biological activity of melittin and inhibitory effect of FBS on hemolysis were determined via hemolytic activity analysis. MTT assay indicated that melittin induced cytotoxic effects in a dose dependent manner on cervical cancer cells and it also revealed dependence on incubation time as well.

Reference dose levels provide a framework to reduce doses variability and aid in the optimization of radiation protection.This study was performed in Khartoum Teaching Hospital in period of January to June 2014. This study performed to assess the entrance surface dose ( ESD) received in Cervical Vertebrae radiographic examination and to analyze effective dose distributions among radiological departments under study. The study was performed in Khartoum Teaching Hospital, covering two x-ray units and a sample of 64 patients. The following parameter were recorded; age, weight, height, body mass index (BMI) derived from weight (kg) and height (m) and exposure factors. The dose was measured for Cervical Vertebrae x-ray examinations, the entrance surface dose (ESD) values were estimated from the x-ray tube output parameters for Cervical Vertebrae AP and lateral examinations. The ESD values were then calculated using IAEA calculation methods. The results of ESD values calculated showed than patient exposure were within the normal range of exposure. The mean ED values calculated were ( 3.85 ±0.04) and (4.02 ±0.05) mGy for Cervical Vertebrae AP and lateral examinations, respectively in department Na1 and (3.99± 0.15) and (4.23± 0.34) mGy, for Cervical Vertebrae Ap and lateral examinations respectively in department Na2, the IAEA standard value of ESD for cervical equal (7), (20) mGy AP and LAT, Further studies are recommended with more number of patients and using more than two modalities for comparison.

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

Close to 20 genotypes of HPV, of the 75 that have been identified, infect the femine genital tract, but four subtypes (16, 18, 31 and 45 have been associated in close to 80% of cervical cancers. this article proposes that in order to design an effective prophylactic vaccine against HPV infection, an adequate immune response should be guaranteed through four goals; a activation of antigens present in the cell; b overcoming the host response and viral genetic variability in the T cell response; c generation of high levels of T and B memory cells; and d persistence of antigens.El potencial uso de vacunas de virus del papiloma humano (VPH en la prevención y tratamiento del cáncer cervical posiblemente será implementado durante los próximos años. Cerca de los 20 genotipos de VPH de los 75 que se encuentran identificados infectan el tracto genital femenino, pero son cuatro subtipos: 16, 18, 31 y 45 los que se han asociado en cerca de 80% a cáncer cervical. En este ensayo se plantea que para poder diseñar una vacuna profiláctica contra la infección de VPH, efectiva, se debe garantizar una adecuada respuesta inmune a través de cuatro metas: a activación de antígenos presentes en la célula; b superar la respuesta del huésped y la variabilidad genética viral en la respuesta de células T; c generación de altos niveles de células T y B de memoria, y d persistencia de antígenos.

Cervical spondylosis anatomy: pathophysiology and biomechanics.

Science.gov (United States)

Shedid, Daniel; Benzel, Edward C

2007-01-01

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.

The objective of this study was to identify the effect of planned follow-up visits on married women's health beliefs and behaviors concerning breast and cervical cancer screenings. The study was conducted using the single-group pre-test/post-test and quasi-experimental study designs. The sample of the study included 153 women. Data were collected using a Personal Information Form, the Health Belief Model (HBM) Scale for Breast Cancer Screening, the HBM Scale for Cervical Cancer Screening, and a Pap smear test. Data were collected using the aforementioned tools from September 2012 to March 2013. Four follow-up visits were conducted, nurses were educated, and telephone reminders were utilized. Friedman's test, McNemar's test, and descriptive statistics were used for data analyzing. The frequency of performing breast self-examination (BSE) at the last visit increased to 84.3 % compared to the pre-training. A statistically significant difference was observed between the pre- and post-training median values in four subscales except for the subscale of perceived seriousness of cervical cancer under "the Health Belief Model Scale for Cervical Cancer and the Pap Smear Test" (p < 0.001). The rate of performing BSE significantly increased after the training and follow-up visits. Also, the rate of having a Pap smear significantly increased after the follow-up visits.

In Japan, the cervical cancer screening rate is extremely low. Towards improving the cervical cancer screening rate, encouraging eligible people to make an informed choice, which is a decision-making process that relies on beliefs informed by adequate information about the possible benefits and risks of screening, has attracted increased attention in the public health domain. However, there is concern that providing information on possible risks of screening might prevent deter from participating. In total, 1,912 women aged 20-39 years who had not participated in screening in the fiscal year were selected from a Japanese urban community setting. Participants were randomly divided into 3 groups. Group A received a printed reminder with information about the possible benefits of screening, group B received a printed reminder with information about possible benefits and risks, and group C received a printed reminder with simple information only (control group). Out of 1,912 participants, 169 (8.8%) participated in cervical cancer screening. In the intervention groups, 137 (10.9%) participated in cervical cancer screening, compared to only 32 (4.9%) of the control group (p < 0.001). In addition, logistic regression analysis revealed that there was no significant difference in screening rate between group A and group B (p = 0.372). Providing information on the possible risks of screening may not prevent people from taking part in cervical cancer screening among a Japanese non-adherent population.

Cervical epidural anesthesia has been used widely for surgery of upper limbs. Although cervical epidural anesthesia with local anesthetic of 2% lidocaine (plain) has demonstrated the safety in respiratory function in spite of unavoidable phrenic and intercostal palsies to certain extent, the replacement of local anesthetics with 2% lidocaine plus epinephrine has not been investigated yet. I conducted this study to look into the effect of 2% lidocaine plus epinephrine on respiratory function. I collected data from 50 patients with mean age of 24 +/- 3 yrs, mean weight of 65 +/- 10 kg, ASA status: I-II without preoperative pulmonary dysfunction undergoing orthropedic open-reduction with internal fixation because of fractures of upper limbs. Cervical epidural space (C7-T1) was approached by hanging-drop method, using a 17G Tuohy needle. A catheter was inserted craniad to a distance of 12 cm. Pulmonary function measurement and arterial blood gas data were obstained before, 20 min, 50 min and 105 min after injection of 12 mL 2% lidocaine with 1:200,000 epinephrine. The anesthesia levels were between C3-T3 and obtained 15 +/- 2 min after injection. Mean arterial blood gas analysis showed mild respiratory acidosis at 20 min (PaCO2: 48 +/- 3 mmHg) and 50 min (PaCO2: 44 +/- 2 mmHg). The measured values of inspiratory vital capacity (IVC), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), peak expiratory flow (PEF) when compaired with control values, were decreased about 18.0% and 12.1% of the control values at 20 min and 50 min respectively. The ratios of FEV1/VC, FEV1/FVC were still within normal limits (> 80%). The results were significantly compatible with the criteria of mild restrictive type of pulmonary function. Cervical epidural anesthesia with 2% lidocaine plus epinephrine could reduce lung volumes and capacities, resulting from partially paralytic intercostal muscles and diaphragm innervated respectively by thoracic

Advanced-stage diagnosis is among the primary causes of mortality among cervical cancer patients. With the wide use of Pap smear screening, cervical cancer advanced-stage diagnosis rates have decreased. However, disparities of advanced-stage diagnosis persist among different population groups. A challenging task in cervical cancer disparity reduction is to identify where underserved population groups are. Based on cervical cancer incidence data between 1995 and 2008, this study investigated advanced-stage cervical cancer disparities in Texas from three social domains: Race/ethnicity, socioeconomic status (SES), and geographic location. Effects of individual and contextual factors, including age, tumor grade, race/ethnicity, as well as contextual SES, spatial access to health care, sociocultural factors, percentage of African Americans, and insurance expenditures, on these disparities were examined using multilevel logistic regressions. Significant variations by race/ethnicity and SES were found in cervical cancer advanced-stage diagnosis. We also found a decline in racial/ethnic disparities of advanced cervical cancer diagnosis rate from 1995 to 2008. However, the progress was slower among African Americans than Hispanics. Geographic disparities could be explained by age, race/ethnicity, SES, and the percentage of African Americans in a census tract. Our findings have important implications for developing effective cervical cancer screening and control programs. We identified the location of underserved populations who need the most assistance with cervical cancer screening. Cervical cancer intervention programs should target Hispanics and African Americans, as well as individuals from communities with lower SES in geographic areas where higher advanced-stage diagnosis rates were identified in this study.

Results from clinical trials in the 1990s led to changes in the recommended treatment for the standard therapy for stage IIB-IVA cervical cancer from radiotherapy alone to chemo-radiotherapy. We conducted the first population-based study in Canada to investigate temporal treatment patterns for cervical cancer and long-term survival in relation to these changes in the treatment guidelines. Detailed information on stage and treatment for 1085 patients diagnosed with cervical cancer in 1984–2008 and identified from the population-based Manitoba Cancer Registry (MCR) in Canada was obtained from clinical chart review and the MCR. Factors associated with receiving guideline treatment were identified using logistic regression. All cause and cervical cancer specific survival were compared in patients who were and were not treated as recommended in the guidelines, using Cox proportional hazards models. The median follow-up time was 6.4 years (range: 0.05–26.5 years). The proportion of women who received guideline treatment was 79 % (95 % confidence interval [CI]: 76–81 %). However, the likelihood of being treated according to the guidelines over time was modified by age (p < 0.0001) and tumour stage at diagnosis (p = 0.002). Women who were treated according to the guidelines after the change in recommended clinical practice (1999–2008) had a significantly lower risk of death from all causes and from cervical cancer. This was driven by lower mortality rates in cases with stage IIB-IVA tumours (all causes of death: hazard ratio [HR] = 0.60, 95 % CI: 0.43–0.82, p = 0.002; cervical cancer related death: HR = 0.64, 95 % CI: 0.44–0.93, p = 0.02). The management of cervical cancer patients in Manitoba, Canada was in good agreement with treatment guidelines although reasons for departure from the guideline recommendations could not be examined further due to lack of data.

The article reports on injuries of the cervical spine occurring during sports activities. An attempt is made to reconstruct the movements which led to the cervical spine injuries in question. 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.

Full Text Available PURPOSE: Human papillomavirus (HPV type 16 is one of the major etiologic factors of cervical cancer. Our study aims to investigate the potentiality of the antiviral clustered regularly interspaced short palindromic repeat (CRISPR/CRISPR-associated Cas9 system (CRISPR/Cas9 targeting the E6 and E7 oncogenes of HPV16 as a potential chemosensitizer of cisplatin (cis-diaminedichloroplatinum II; CDDP for cervical cancer. METHODS: Specifically, the therapeutic efficacy of combination of CDDP and HPV16 E6 + E7-CRISPR/Cas9 was assessed in cervical cancer cells and cervical cancer xenograft models. RESULTS: In vitro experiments showed that long-term exposure of SiHa cells to the HPV16 E6 + E7-CRISPR/Cas9 induced apoptosis, and its pro-apoptosis effect became more obvious when combined with CDDP. In vivo study found the efficacy of the combination of HPV16 E6 + E7-CRISPR/Cas9 and CDDP were superior to either of the treatments in term of apoptosis induction and metastasis inhibition. CONCLUSION: Collectively, our results suggested that HPV16 E6 + E7-CRISPR/Cas9 could be an effective sensitizer of CDDP chemotherapy in cervical cancer.

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

Effective female education on cervical cancer prevention has been shown to increase awareness and uptake of screening. However, sustaining increase in uptake poses a challenge to control efforts. Peer health education has been used as an effective tool for ensuring sustained behavior change. This study was undertaken to assess the effectiveness of peer health education on perception, willingness to screen and uptake of cervical cancer screening by women. A before and after intervention study was undertaken in 2 urban cities in Enugu state, Nigeria among women of reproductive age attending women's meeting in Anglican churches. Multistage sampling was used to select 300 women. Peer health education was provided once monthly for 3 consecutive sessions over a period of 3 months. Data was collected at baseline and after the intervention using pre-tested questionnaires. Descriptive statistics and tests of significance of observed differences and associations were done at p-value of education, employment status and parity (p education is an effective strategy for increasing women's perception of benefits of early detection of cervical cancer through screening. It is also effective for increasing their practice of screening for cervical cancer.

Objective: To evaluate the effectiveness of CT-guided periradicular therapy (PRT) in cervical and lumber radicular syndromes. Methods: Seventy two cases of cervical and lumbar radicular syndromes were treated by CT-guided PRT. During PRT, 10-20 mg of Triamhexal and 3-4 ml of Carbostesin 0.25%(Bupivacainhydrochlorid) were injected into the space around the corresponding spinal root, once a week, all together six times as a course. Results: Four hundreds and forty six PRT procedures were carried out in 72 patients having a successful puncture and a satisfying spread of Triamhexal and Carbostesin around the spinal nerve root space for every time. After 6 to 24 months follow up, 62 patients showed a significant pain reduction or complete disappearance. Moderate improvement was not noted in 6 and no improvement in 4. The effective rate was 94.4% without any correlative complication. Conclusions: CT-guided PRT is an effective, easy and safe procedure to treat patients with refractory cervical or lumbar radicular pain syndromes. (authors)

2008-06-01

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 establish a new predictor of outcome for human cervical carcinoma treatment, the relationship between WAF1 mRNA levels during treatment, human papilloma virus (HPV) infection and tumor radiosensitivity were investigated. Forty patients with uterine cervical carcinoma were treated with definitive radiotherapy. Only those patients who beard wild-type p53 were included into present clinical trial. p53 status was investigated using SSCP analysis. HPV E6 was determined by PCR, WAF1 mRNA was estimated by RT-PCR. Twenty-one patients achieved complete response (CR), 11 patients achieved partial response (PR), and 8 patients had no change (NC). The increase in WAF1 mRNA after irradiation at 10.8 Gy positively correlated both with better treatment response and improved survival. Although the infection by HPV did not directly influence on the survival rate, it decreased the inducibility of WAF1. p53-dependent activation of WAF1 gene expression during treatment may be a strong determinant of the efficacy of cervical cancer radiotherapy.

The surgical treatment of cervical radiculopathy has centered around anterior cervical discectomy and fusion (ACDF). Alternatively, the posterior cervical laminoforaminotomy/microdiscectomy (PCF/PCM), which results in comparable outcomes and is more cost-effective, has been underutilized. Here, we compared the direct/indirect costs, reoperation rates, and outcome for ACDF and PCF vs. PCM using PubMed, Medline, and Embase databases. There were no significant differences between the re-operative rates of PCF/PCM (2% to 9.8%) versus ACDF (2% to 8%). Direct costs of ACDF were also significantly higher; the 1-year cost-utility analysis demonstrated that ACDF had $131,951/QALY while PCM had $79,856/QALY. PCF/PCM for radiculopathy are safe and more cost-effective vs. ACDF, and have similar clinical outcomes.
